Abstract

PURPOSE:To miniaturize and simplify the whole of a device by using a planet gear mechanism to switch a driving force transmission route and selectively transmitting the driving force of one driving motor to the cassette loading mechanism side and the tape loading mechanism side. CONSTITUTION:The planet gear mechanism consisting of an output member 50, a planet gear 91, a sun gear 92, and an internal gear 111 is freely rotatably attached to a shaft 48A. If the gear 111 and the output member 50 are provided with the cassette loading driving part and the tape loading driving part respectively, the gear 91 turns on its axis there to rotate the gear 111 and a cassette is loaded when rotation of the member 50 is controlled by a position control member 94 and the gear 92 is rotated by the driving force of the driving motor in this state. If the control of the member 50 is released and the gear 111 is controlled, the gear 91 is turned around the gear 91 by the rotating force of the sun gear to rotate the member 50 and a tape is loaded when the sun gear is rotated by the driving force of the driving motor in this state. Thus, the driving force of one driving motor is selectively transmitted to the cassette loading mechanism side and the tape loading mechanism side, and the whole of the device is miniaturized and simplified.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a magnetic recording and reproducing device that records and reproduces tape by winding it around a rotating drum. and a tape loading mechanism for pulling out the tape from the cassette mouth of the cassette loaded into the device and winding it onto the drum, in particular, by a single drive motor, the cassette loading mechanism and the tape loading mechanism The present invention relates to a drive mechanism for cassette loading and tape loading that drives both loading mechanisms.

[Prior Art] Conventionally, in a cassette loading mechanism of a magnetic recording and reproducing device that records and plays back tape by winding it around a rotating drum, when loading a cassette, a cassette inserted from a cassette insertion slot is connected to a cassette guide. match,
After drawing the cassette into the cassette holder as the cassette guide moves forward, the cassette holder is lowered and set at the cassette loading position. Also, when unloading a cassette, after raising the cassette holder,
The cassette is ejected from the cassette holder as the cassette guide retreats.

In addition, the tape loading mechanism of a magnetic recording/playback device is
After the cassette is set at the cassette loading position by the cassette loading mechanism as described below-1-,
By advancing the tape loading member from inside the cassette mouth of this cassette, the tape is pulled out from inside the cassette mouth, wound around the rotating drum, and tape loading is performed. Rotate the reel base,
Tape unloading is in progress.

Furthermore, when driving such a tape loading mechanism, a mode member that switches modes is used to drive and control the tape loading member, thereby reducing the size and size of the tape loading mechanism.
Techniques aimed at simplification have been proposed.

This technology uses a drive motor for mode switching to operate the mode members as appropriate, drive and control various mechanisms such as the tension control mechanism and brake mechanism, and switch to at least three mode positions such as stop, play, and pause. In addition to performing mode switching, this mode member drives and controls the tape loading member to perform tape loading and tape unloading, and is considered promising from the viewpoint of miniaturization and simplification of the entire apparatus.

[Problems to be Solved by the Invention] Incidentally, in a magnetic recording/reproducing device having the above-described cassette loading mechanism and tape loading mechanism, there is a strong demand for reducing the number of drive motors from the viewpoint of downsizing and simplifying the configuration. has been done.

However, the tape loading mechanism and the cassette loading mechanism have completely different operating mechanisms and operating timings, and are not related in terms of mechanical operation, so conventionally they have had to be driven by separate drive motors.

On the other hand, when a mode member that switches modes is used to drive the tape loading mechanism, the operation of the tape loading mechanism is based on the relationship between switching the mode member.
1-1 The operation content is even more different from the operation of a cassette loading mechanism that does not require such switching. Therefore, in this case, it is even more difficult to use the drive motor for both the chip loading mechanism and the cassette loading mechanism.

As mentioned above, in conventional magnetic recording devices, separate drive motors were used for the cassette loading mechanism and the tape loading mechanism, so the mechanism became larger and more complex as the number of drive motors increased. Moreover, the circuit configuration for supplying power to the drive motor becomes complicated.

In addition, in the cassette loading mechanism, the timing of each operation of the cassette holder and the cassette guide is different.2.In particular, since the load applied to the cassette holder is large, the operating stroke of the drive member that operates them becomes large, and the mechanism as a whole The disadvantage was that the operating space was expanded. Furthermore, a stroke absorption mechanism for positioning the cassette guide is required, which has the disadvantage of complicating the configuration.

The present invention was proposed to solve the problems of the prior art as described above, and its purpose is to enable the same drive motor to drive both the cassette loading mechanism and the tape loading mechanism. An object of the present invention is to provide an excellent drive mechanism for cassette loading and tape loading, which can reduce the number of drive motors and contribute to downsizing and simplifying the entire device.

In particular, in a magnetic recording/reproducing device having a tape loading mechanism with a mode switching function, it is possible to load/unload a cassette, load/unload a tape, and switch the modes of various mechanisms using the same drive motor. One of the purposes is to further contribute to the miniaturization and simplification of the entire device and to realize a more practical magnetic recording and reproducing device.

Another purpose is to reduce the operating space in the cassette loading mechanism and to make it possible to omit the stroke absorbing mechanism for guiding the cassette, thereby making the cassette loading mechanism itself more compact and simple.

[Means for Solving the Problems] The drive mechanism for cassette loading and tape loading according to the present invention utilizes a planetary gear mechanism to switch the drive force transmission path, and uses the same drive motor to perform 13. The resulting driving force is selectively transmitted to either the cassette loading mechanism side or the tape loading mechanism side.

That is, the drive mechanism for cassette loading and tape loading according to the present invention includes: a drive motor; a sun gear that is rotatably provided and rotates by the driving force of the drive motor; and a sun gear that is rotatably provided coaxially with and independently of the sun gear. , an internal gear having internal teeth formed to surround the outer periphery of the sun gear; an output member rotatably provided coaxially and independently of the sun gear and the internal gear; and an output member rotatable on the output member. It is supported by the sun gear and the internal gear so that it always meshes with the internal gear, and the operating load on the internal gear is
If it is smaller than the operating load on the output member side, the rotational force of the sun gear causes it to rotate on its own axis and rotate the internal gear.
When the operating load on the internal gear side is larger than the operating load on the output member side, a planetary gear that revolves around the sun gear and rotates the output member by the rotational force of the sun gear; a position regulating member that selectively regulates the rotational position; provided on either the internal gear or the output member, and moves in accordance with the rotation of the internal gear or the output member in one direction; A cassette loading drive section that drives the cassette loading mechanism in the cassette mounting direction and moves according to rotation in the other direction to drive the cassette loading mechanism in the ejection direction; A cheap loading drive that is provided on the member on the side where it is not provided and moves according to the rotation of the internal gear or the output member in at least one direction to drive the tape loading member in the tape loading direction or the tape unloading direction. It is characterized by having a part.

Furthermore, when the tape loading mechanism is driven by the tape loading drive unit, a mode member is provided that moves in an arbitrary direction according to the movement of the cheap loading drive unit, and the loading member is moved in the tape loading direction or tape unloading direction according to the movement of the mode member. It is desirable to have a configuration in which at least one mechanism other than the tape loading mechanism is controlled by the movement of the mode member.

Further, the drive configuration of the cassette loading mechanism by the cassette loading drive section includes a cam plate that reciprocates in any direction according to the movement of the cassette loading drive section, and is configured to drive the cassette holder according to the movement of the cam plate. At the same time, it is desirable to provide a sub-plate so as to overlap the cam plate, to urge the cassette guide by an elastic member in the direction of overlapping the cam plate, and to drive the cassette guide in accordance with the movement of the sub-plate.

[Function] In the present invention having the following configuration, the driving force of the same drive motor is transmitted to the cassette loading mechanism through a planetary gear mechanism consisting of a sun gear, an internal gear, an output member, and a planetary gear. Alternatively, since the signal can be transmitted to the tape loading mechanism by appropriately switching, the same drive motor can drive both the cassette loading mechanism and the tape loading mechanism.

For example, if the internal gear is provided with a cassette loading drive section and the output member is provided with a tape loading drive section, the position regulating member controls the rotation of the output member while the drive motor is driven. By rotating the sun gear by force, the planetary gears rotate on the spot due to the rotational force of the sun gear, rotating the internal gear, and the cassette loading can be performed by the cassette loading drive section of the internal gear.

When this cassette loading is completed, if the restriction of the protruding horn member by the position restriction member is released and the internal gear is restricted instead, and the sun gear is rotated by the driving force of the drive motor in this state, the sun gear will rotate. The force causes the planetary gears to revolve around the sun gear to rotate the output member, and tape loading can be performed by the output member's cheap loading drive.

In addition, in the case of tape unloading and cassette unloading, the rotation direction of the drive motor is reversed, the internal gear is first regulated, and tape unloading is performed, and when tape unloading is completed, the position of the output member is regulated. Cassette unloading can be performed by switching to .

Furthermore, conversely, if the output member is provided with a cassette loading drive section and the internal gear is provided with a tape loading drive section, the same can be done by reversing the side to be regulated by the position regulating member from the above example. Additionally, cassette loading and tape loading, or tape unloading and cassette unloading can be performed successively.

In addition, when driving tape loading, if the tape loading member is configured to be driven and controlled using a mode member that switches modes of other mechanisms, cassette loading Φ unloading, tape loading/unloading, etc. In addition, mode switching of various mechanisms can be performed by the same drive motor, which is more effective.

On the other hand, when driving the cassette loading mechanism, if a cam plate and a sub-plate are provided overlappingly and connected via an elastic member to drive the cassette holder and the cassette guide respectively, the operation timing may be different. Since each movement of the cassette holder and cassette guide can be performed individually, overlapping the movement strokes can contribute to reducing the movement space of the entire mechanism. Since it can be used as an absorption mechanism, it also simplifies the configuration.

■Reel drive system (swing arm mechanism, friction mechanism,
Transmission torque switching mechanism) ...Figures 19 to 26 In Figures 19 to 23, 25A and 25B are the left and right reels, and the left reel 25A is the supply side reel during play. Hereinafter, the reel 25B on the right side will be referred to as the S reel 25A, and since it becomes the reel on the take-up side during play, it will be referred to as the T reel 25B.

As shown in FIG. 24, on the disk 25AaJx of the S reel 25A, an FF idler drive arm (transmission torque switching member) 27 is arranged around the reel shaft. FF
The idler drive arm 27 is rotatably provided by a shaft 27A, and is located at the lock position (19th
21) and a clockwise (left side) release position, and is constantly urged in the locking direction by an elastic member 28. An FF idler gear 29 is attached to the support shaft 27B at one end of the FF idler drive arm 27, and when the FF idler drive arm 27 is in the lock position, the FF idler gear 29 meshes with a friction mechanism 30, which will be described later. It is designed to lock the slip. A cam follower 27C is provided at the other end of the FF idler drive arm 27, and the mode member 6
is inserted into the cam hole 6D of the mode member 6, and is driven in the release direction by the operation of the mode member 6.

In addition, in FIG. 24, 7 indicates a chassis, and this chassis 7 has a rotation support shaft 27B of the FF idler drive arm 27 in order to mesh the FF idler gear 29 with the friction mechanism 30 in a proper state. Holes that regulate the position (
(hereinafter referred to as regulation hole) 7H (Figures 19 to 23)
is provided. Due to the dimensional accuracy of this regulation hole 7H and the shaft 7G of the friction mechanism 30 installed in the chassis 7, the axis distance between the FF idler gear 29 and the friction mechanism 30 is maintained. As shown, the FF idler gear 29 is connected to the friction mechanism 30.
When the FF idler drive arm 27 is engaged with the FF idler drive arm 27, the FF idler drive arm 27 is
By simply rotating the support shaft 27B until it comes into contact with the edge of the regulating hole 7H, a proper meshing state can be automatically achieved.

In FIGS. 19 to 23, 25, and 26, 31 is an idler gear, 32 is a swing arm, and 34 is a pulley.

The pulley 34 is connected to a reel drive motor (not shown), rotates counterclockwise or clockwise, and drives the T-reel 25 via the friction mechanism 30 and idler gear 31.
This is a member that drives the B or S reel 25A. In this case, a motor that can rotate in two directions and switch between high and low speeds is used as the reel drive motor.
It is also used as the capstan motor that drives 1.

The swing arm 32 has a sleeve 32A provided in one direction, and the sleeve 32A is rotatably supported by a shaft 7G implanted in the chassis 7. A support shaft 32C is provided at the free rotation end of the swing arm 32, and the idler gear 31 is rotatably supported by the support shaft 32C.

The friction mechanism 30 is a mechanism that transmits the rotational torque transmitted from the drive gear 34 to the T reel 25B or the S reel 25A via the idler gear 31.
0A1 driven gear 30B1 and sleeve part) fA 30
It is composed of C.

The drive gear 30A is a gear that is always meshed with the pulley 34. This drive gear 30A has a sleeve 30Aa.
is integrally provided, and is rotatably supported by the sleeve 30Aa on the outer periphery of the sleeve 32A of the swinging arm 32, whereby the entire friction mechanism 30 is rotatably supported with respect to the swinging arm 32. ing. Then, on the outer periphery of the sleeve 30Aa of this drive gear 30A,
The sleeve portion $430C1 and the driven gear 30B are removed in sequence.

The driven gear 30B is a gear that is always meshed with the idler gear 31. This driven gear 30B is made of magnetic resin that is magnetized and made into a magnet.
They are arranged so as to overlap below the drive gear 30A. On the other hand, a hysteresis plate 30Ab is provided on the back surface of the drive gear 30A facing the driven gear 30B, and between this hysteresis plate 30Ab and the driven gear 30B made of magnetic resin. Historque that occurs, and
The combined torque of the friction torque generated between the sleeve member 30C and the hysteresis plate 30Ab is the
A is transmitted to the driven gear 30B.

Note that when the FF idler gear 29 is engaged, the drive gear The side diameter is made slightly larger than that of the driven gear to ensure rotational transmission.

Such a composite torque is transmitted from the drive gear 30A to the driven gear 30B when the aforementioned FF idler gear 29 is released in the play state (FIG. 23) or the reverse play state (FIG. 22). That is,
When the FF idler gear 29 is released, the drive gear 3
The driven gear 30B becomes able to slip with respect to 0A, and the driven gear 30B becomes ? >The obtained resultant torque is transmitted to the T-reel 25B or S-reel 25A on the winding side via the idler gear 31, and as a result, the winding speed of the reel is changed according to the winding diameter of the tape. , the reel is wound.

On the other hand, the FF state (Fig. 20) and the REW state (second
1), a large torque is required and there is no need to change the reel winding speed, so the FF idler gear 29 is meshed with the friction mechanism 30 as shown in FIG. 12. In this way, when the FF idler gear 29 is engaged with the friction mechanism 30, the rotational transmission between the drive gear 30A and the driven gear 30B is
Since this is done via the F idler gear 29, the pre-34
The rotational torque of the reel drive motor transmitted through the
T reel 2 via driven gear 30B1 idler gear 31
5B or S reel 25A.

Further, a leaf spring 33 is inserted in a compressed state between the lower end of the sleeve 30Aa of the drive gear 30A and the seat surface of the sleeve 32A of the swing arm 32, and is caused to swing together with the drive gear 30A by the stopper 32B. It is attached to the sleeve 32A of the arm 32. With this configuration, frictional torque is generated between the drive gear 30A and the swing arm 32, and in response to the rotation of the drive gear 30A, the swing arm 32 rotates in the same direction around the shaft 7G. Accordingly, the idler gear 31 is rotated toward either the T reel 25B side or the S reel 25A side, thereby meshing the idler gear 31 with either one of the reels.

In this way, in this embodiment, all the rotational force of the swinging arm 32 is obtained from the drive gear 30A, and the transmitted torque from the driven gear 30B is used as the rotational force of the swinging arm 32. There are no reels, and all of them are efficiently transmitted to the T reel 25B or S reel 25A.

(2) Brake mechanism: FIGS. 27 to 32 As shown in FIGS. 27 to 31, a reel brake 35 is provided in front of the center of both sides of the rills 25A and 25B. Brake pads 36A are provided on both left and right sides of the rear end of the reel brake 35.

36B is installed, and these brake pads 36A,
36B are the reels 25A and 25B on the corresponding side, respectively.
It is designed to come into pressure contact with the The reel brake 35 is provided with a rear guide groove 35A and a front regulation hole 35B, into which fixing pins 37 and 38 fixed to a reel stand mounting plate (not shown) are respectively inserted. In this case, the reel brake 35 is rotatable about the fixing pin 37 in the guide groove 35A and movable in the front and back direction, and the amount of rotation is regulated by the regulation hole 35B.
It moves between the rear double-sided pressure contact position (Fig. 28), the one-side pressure contact position slightly rotated clockwise at the center (Fig. 27), and the front release position (Figs. 29 to 31). It has become. FIG. 32 shows brake pads 36A, 36
It is a figure showing the arrangement angle of B. As shown in FIG. 19, the left and right brake pads 36A, 36B are connected to the center of rotation of the reel brake 35 (the center of the fixing pin 37) and the contact point between the S reel 25A, T reel 25B and the brake pad 36A. , the S reel 25A, and the T reel 25B are arranged so that the angle formed by the rotation center thereof is approximately 120°.

The reel brake 35 is driven by a brake release member 39 and an elastic member 40.

The brake release member 39 is rotatably provided at a support 39A, and a cam follower 39B provided at a portion thereof is inserted into the cam hole 6D of the mode member 6, while a cam follower 39B provided at one end near the cam follower 39B is inserted into the cam hole 6D of the mode member 6. A restriction pin 39C is inserted into an engagement hole 35C provided on the left side of the brake 35. That is, the brake release member 39 is connected to the cam hole 6
D, the rotary free end on the side with the cam follower 39B and the regulating pin 39C is switched to three positions: a release position where it is at the forefront, a one-side pressure contact position in the middle, and a both-side pressure contact position at the rear end. It has a function of switching the brake 35 to three corresponding positions. Further, the elastic member 40 always biases the brake 35 in the pressure contact direction, and this biasing force becomes a pressure contact force of the brake 35, and at the same time, a pressure contact force of the brake release member 39 to the groove cam 6D of the cam follower 39B. It becomes.

By the way, in the pose state, the rills 25A on both sides,
Since it is necessary to stop 25B reliably and wait for the next mode, the pre-ki pads 36A and 36B on both sides
It is necessary to press the reels 25A and 25B into contact with the reels 25A and 25B, whereas in the FF/REW mode, the reels 25 on both sides
It is necessary to rotate A and 25B at high speed, and brake pads 36A and 36B on both sides must be released.

Further, if it is desired to stop at a predetermined position when detecting the tape end or searching for the tape, the tape must be stopped instantaneously because the tape is being fed at high speed in the FF/REW mode.

Therefore, if you switch modes in such a case,
The tape greatly overruns and can only be stopped at a position far beyond the predetermined position, making it impractical.

From the above two points, the brake mechanism is equipped with the following: Before shifting to FF/REW, the brake is released, and by electrically holding this state, the brake operation can be instantaneously controlled by the 0N10FF of the power supply. Make it possible and use FF/
Entering REW mode is required.

Therefore, in this embodiment, from pause mode to FF/
When switching to the REW mode, the mode member 6 in the fast wind/pause position is moved to the reverse play position, the brake release member 39 is moved to the forward release position, and the brake release member 39 is activated by energizing the plunger 45. After holding the mode member 6 in the forward release position, the mode member 6 is returned to the instep winding φ pose position, and as a result,
While holding the mode section If6 in the fast winding/pause position,
The brake release member 39 and the reel brake 35 are configured to be held in the forward release position only by the attraction force of the plunger 45.

In this case, the plunger 45 is arranged near the rear end of the brake release member 39, and a plunger core 41 is arranged opposite to the plunger 45, and this plunger core 41 is connected to a support shaft at one end of the plunger arm 42. 42B, and the other end of the plunger arm 42 is rotatably attached to a shaft 43. The plunger arm 42 is always urged toward the opening side by the elastic portion 1fA' 44A.

An engagement hole 42C is provided in a part of the plunger arm 42 near the plunger core 41, into which the engagement pin 39D of the brake release part 39 is inserted, and the elastic part) f)
are connected via E 44 B, thereby
The plunger arm 42 rotates forward toward the release side as the brake release member 39 rotates to the rear pressure contact position, and rotates toward the plunger contact side as the brake release member 39 rotates toward the release side. It is supposed to be done.

That is, when the mode member 6 is moved from the upper winding/pause position to the reverse play position, the brake release member 39 is moved to the release position, and the plunger arm 4 is moved to the release position.
2 moves to the plunger contact position, and its plunger core 41 comes into contact with the plunger 45. In this way, when the plunger 45 is energized in a state where the brake release member 39 is in the release position, the plunger 1.42 is in the contact position, and the plunger core 41 is in contact with the plunger 45. In this case, the plunger 45 attracts and holds the plunger core 41, and the brake release portion 49 is held in the release position via the plunger arm 42. In this case, the adsorption force by the plunger 45 is set to be much larger than the urging force of the elastic member 40, so that even if the mode member 6 returns to the 11-winding pose position, the brake release member 49 does not return to the pressing position. It is held in the released position by the attraction force of the plunger 45 against the elastic member 40.

■Preload mechanism...Figures 19 to 23 As shown in Figures 19 to 23, the brirod 46 has a shaft 46A.
It is rotatable around the left pressure contact position (22nd
) and the release position on the right side (Figures 19 to 21, 2).
(Figure 3). A felt 46B is attached to the free rotation end of the preload 46,
When the preload 46 is in the pressure contact position, the T reel 25B
The disc 25Ba is brought into pressure contact with the disc 25Ba. The preload 46 is constantly urged in the pressure contact direction by an elastic member 47. In addition, at another end of the Brirod 46,
A cam follower 46C is provided and comes into contact with the cam 6E,
It is designed to be driven to the release side.

Operation of this embodiment* The operation of this embodiment having the following configuration will be described below.

■Cassette loader start state...Figures 2, 8, 11, 14, 19, and 27 In the cassette loader start state, the power motor (not shown) is stopped. As shown in FIGS. 2(A) and 2(B), the internal gear 111 of the planetary gear mechanism
is stopped at the rotational position furthest in the counterclockwise z1 direction (cassette unloading position), and the output member 50 is stopped at the rotational position furthest clockwise (tape unloading position).

Therefore, the drive pin (cassette loading drive unit) 111c of the internal gear 111 is at the frontmost cassette unloading position, and the drive roller (tape loading drive unit) 50A of the output member is at the rightmost tape unloading position. be.

Therefore, first, on the cassette loading mechanism side, as shown in FIGS. 8 and 11, the cam plate 10
1 and sub-plate 1-102 are at the most forward cassette unloading position, the engaging portion 102A of the sub-plate 102 and the engaging roller 103A of the guide arm 103 that is in pressure contact with the engaging portion 102A of the sub-plate 102 are at the front,
is at the most counterclockwise rotation position. Therefore, since the guide groove 103B at the end of the guide arm 103 opposite to the engagement roller 103A is located at the rear, this guide groove 10
3B, the cassette guide 1.04, which is engaged by the engagement roller], 04A, is in the rear cassette unloading position, ie in a standby state for cassette insertion.

Also, the cam roller 107A of the right holder arm 107
However, the cassette holder 110 is located at the rear end of the holding horizontal portion 101Aa of the cam 101A of the cam plate 101, that is, at the most raised position, and is supported by the shirt l-107B that holds this cam roller 107A, not shown. Resisting the biasing force of the elastic member, the cassette is in the raised position, that is, in a standby state for cassette suction.

Next, on the tape loading mechanism side, as shown in FIG. 14, the connecting arm 49 is located most clockwise, and the mode member 6 is located most left at the stop position.
The left and right tape loading drive parts 4A and 4B are unloading parts 5Aa of the groove cams 6A and 6B of the mode member 6, respectively.

6Ba to each cam follower 4Ac.

4Bc is pressed, and the elastic members 5A and 5B are driven and held at the unloading position of J' (after resisting the -J force).

Along with this, the left and right tape loading drive members 4A,
Tape loading members engaged with 4B respectively
A, IB are in the rear tape unloading position (corresponding to the inside of the cassette mouse in the cassette loading state).

Further, the pinch arm 8 is held in a state in which the cam follower 8C is pressed by the unloading portion 6Cb of the grooved cam 6C of the mode member 6, and is driven to the rear unloading position against the biasing force of the elastic member 10. Therefore, the pinch roller 9 and tape guide 12 are in the rear storage position (corresponding to the inside of the cassette mouse in the cassette loading state).

Further, since the left tape loading drive member 4A is at the rear unloading position, the left tape guide support member 13 is not pressed by the tape loading drive member 4A, but is moved backward by the biasing force of the elastic member 15. In the unloading position, the tape guide 14 is therefore in the rear storage position (corresponding to the inside of the cassette mouth in the cassette loading state).

On the other hand, as shown in FIG. 19, the tension arm 16 is
The cam follower 16D is located within the groove of the mode member 6 at 1.6A.
It is in a state where it is mounted on the release part 6Ad and rotated to the left release position against the elastic member 19, and accordingly,
The band brake 18 is a disc 25 of an S reel 25A.
Separated from Aa, the S reel 25A is in a state where it can freely rotate.

Further, the FF idler drive arm 27 has its cam follower 27C connected to the lock portion 6Da of the cam hole 6D of the mode member 6.
Therefore, the FF idler gear 29 meshes with the friction mechanism 30 to lock it, and is directly connected to the pulley 34 to connect the S reel 25A.
Alternatively, it is in a state where it is transmitted to the T-cruise 25B side.

As shown in FIG. 27, the brake release member 39 is in the one-side pressure contact position because its cam follower 39B is located at the one-side pressure contact portion 6DC of the cam hole 6D.

Along with this, the reel brake 35 is also in the pressure contact position on one side, and only the brake pad 36B on the T reel 25B side is in the T reel 25B side.
It is in pressure contact with the reel 25B.

Further, as shown in FIG. 19, the preload 46 is in the release position because its cam follower 46C is located at the release part 6Ea of the cam 6E, and the felt 46B is held at a position away from the disc 258a of the T reel 25B. has been done.

In addition, in the cassette loader start state as described below, as shown in FIG.
B and holds the output member 50 at the most clockwise rotational position (tape unloading position), while the stopper pin 95B contacts the outer peripheral surface of the internal gear 111 to enable its rotation. . In this state, the internal gear 11
1 rotates clockwise by a predetermined stroke until the stopper pin 95B reaches the regulating groove 111B, that is, until just before the completion of the cassette loading mode, which will be described later.
The tape loading mechanism is held stationary.

In addition, in the explanation of item 1, the tape loading mechanism side was explained according to FIG. 14, but this FIG.
To be precise, this is a diagram showing a stop state, which will be described later, which corresponds to a state in which the output member 50 is slightly rotated from the cassette loading state shown in FIG. 2, but the states below the connecting arm 49 are exactly the same. , convenience-L was used.

■Cassette loading mode (and drive switching)...
Figure 2 → Figure 3 - Figure 4, Figure 8 → Figure 9 → Figure 10, Figure 11 → Figure 12 → Figure 13 (Figure 14, Figure 19, Figure 27) When a cassette (not shown) is inserted from the cassette loader start state as shown in FIGS. 2, 8, and 11, and the cassette guide 104 engages with the cassette and moves forward by a predetermined stroke, the cassette detection switch The plate 126 rotates counterclockwise, the cassette detection switch 127 turns off (cassette insertion detection), the power motor starts, and the final gear 93 of the reduction mechanism gear train rotates in the direction of the hour hand.

As the final gear 93 rotates, the sun gear 92 of the planetary gear mechanism rotates in the counterclockwise direction. At this time, as described above, the stopper pin 95A of the stopper plate 95 fits into the regulation groove 50B of the output part 50, and the output part trA' 5
The stopper pin 95B abuts against the outer circumferential surface of the internal gear 111 to enable its rotation. Therefore, the output member 50
does not rotate, and according to the rotation of the sun gear 92, the planetary gear 9
1 rotates clockwise on the spot, and the internal gear 111 starts rotating clockwise.

Due to the rotation of this internal gear 111, the drive pin 111
Since C starts moving backward, the cam plate 101 engaged with the drive pin (cassette loading drive section) IIIC also starts moving backward, and cassette loading starts.

That is, as the drive pin 111C starts to retreat, the cam plate 101 and the sub-plate 102 connected thereto by the elastic member 112 start to retreat together. With this backward movement, the engaging portion 102 of the sub-plate 102
The engagement roller 103A is pressed by A and starts to rotate clockwise, and the guide groove 103B at the other end moves forward.
The cassette guide 104 engaged by 04A is
Advancement is started from the rear cassette unloading position, and suction of the cassette into the cassette holder 110 is started.

In this case, on the cassette holder 110 side, the cam roller 107A of the right holder arm 107 is connected to the holding horizontal portion 101Aal of the cam 101A of the cam plate 101.
-, the cassette holder 110 is held in the cassette raised position.

When the internal gear 111 further rotates clockwise and the cassette guide 104 reaches the forward suction position as shown in FIGS. 9 and 12, the suction of the cassette into the cassette holder 110 is completed. The cassette holder 110 is held at the same position by a position regulating member (not shown), and the guide arm 103 and sub-plate 102 that are interlocked therewith also stop operating.

At this point, as shown in FIG. 12, the cam roller 107A of the right holder arm 107 is connected to the operation switching portion at the tip of the holding horizontal portion 101Aa of the cam 101A of the cam plate 101, that is, the lifting inclined portion 101.
It has reached a position where it touches the rear end of Ab.

Therefore, when the internal gear 111 is rotated clockwise after the cassette suction is completed, the cam play 1
-101 is further retreated, and the cam roller 107A of the right holder arm 107 is moved to the cam 10 of the cam plate 101.
Start descending along the ascending/descending slope 101Ab of 1A,
Along with this, the cassette holder 110 begins to descend, and the cassette begins to descend to the cassette loading position.

In this case, the cassette guide 104, the guide am 103,
The connection structure leading to the cam plate 102 and the sub-plate 102 is fixed as described above, so the cam plate 10 as shown below
1, the sub-plate 102 is moved back against the biasing force of the elastic member 112 that connects both plates 101 and 102.
is carried out independently. Further, the accumulated force of the elastic member 112 expanded by the relative movement stroke of the cam plate 101 with respect to the sub-plate moves the connecting structure including the sub-plate 102, the guide arm 103, and the cassette guide 104 to the suction position. It acts as a holding force.

Immediately before the completion of the lowering of the cassette holder 110, that is, immediately before the completion of cassette loading, the planetary gear mechanism starts drive switching as shown in FIG. 3. That is, when the stopper pin 95B reaches the inclined part of the regulation groove 111B of the internal gear 111, the stopper plate 95 becomes rotatable, and the stopper pin 95A on the opposite side
is pressed against the inclined part of the regulation groove 50B of the output member 50,
The stopper plate 95 rotates clockwise, and the internal gear 1
As the stopper pin 95B continues to rotate, the stopper pin 95B fits into the regulation groove 111B of the internal gear 111, and at the same time, the stopper pin 95A becomes able to ride on the outer circumferential surface of the output member 50 from the inclined part of the regulation groove 50B. Therefore, the output member 50 becomes rotatable and starts rotating counterclockwise.

As a result of such a switching operation, as shown in FIG.
When the output member 50 is completely fitted into the inside B, the output member 50 is held at the most clockwise rotational position (cassette loading position), and the output member 50 becomes rotatable when the stopper pin 95A completely rides on its outer peripheral surface. Drive switching is complete. This drive switching state continues until the output member 50 reverses and rotates in the time=1 direction until the stopper pin 95A reaches the regulating groove 50B again, that is, various tape modes to be described later are performed and the tape unloading mode is completed. After that, the cassette loading mechanism is maintained in the cassette loading state as shown in FIGS. 10 and 13 during tape loading/unloading and various tape modes.

Further, at the time of completion of the drive switching as described in -1- below, as shown in Figs. 10 and 13, the cam pre 1-101
has reached the rear cassette loading position, and the cam roller 107A of the right holder arm 107 has reached the lower end of the ascending/descending inclined portion 101Ab of the cam 101A of the cam plate 101, so that the cassette holder 110 and the cassette holder 110 held by it have reached the rear cassette loading position. The loaded cassette has reached the cassette loading position.

On the other hand, at the time when this cassette loading is completed, the tape loading mechanism is in a stopped state as shown in FIG. 14. The output member 50 rotates slightly due to the above switching operation, and the first drive roller 5
The OA also moves slightly, but as shown in FIGS. 3 and 4, this movement is performed within the relief of the groove 49B of the connecting arm 49, so the connecting arm 49 is not moved. The connecting arm 49 is maintained at the most clockwise position as shown in FIG.
reaches the end of the engaging portion of the groove portion 49B. Furthermore, in this stop state, the states of each member on the tape loading mechanism side, including the mode member 6, are exactly the same as in the cassette loading start state described above, so a description thereof will be omitted here.

Furthermore, when the cassette loading is completed as described above,
When the power motor is stopped, the tape loading mechanism is held in a stopped state; however, in actual use, there is no stopping operation between cassette loading and tape loading when fishing on a boat; is then rotated, and tape loading is performed continuously as described below.

■Tape loading mode...Fig. 4 - Fig. 5, Fig. 14 -> Fig. 15, Fig. 19 -> Fig. 20 (Fig. 21), Fig. 27 - Fig. 28 As mentioned above, cassette loading Upon completion, play J1
1 gear machine (1) After this drive switching is performed, as shown in Fig. 4, the stopper pin 9 of the stopper plate 1/95
5B fits into the regulation groove 111B of the internal gear 111 to hold the internal gear 111 at the most clockwise rotational position, while the stopper pin 95A comes into contact with the outer peripheral surface of the output member 50 to prevent its rotation. It is possible. Therefore, when the power motor rotates further, the final gear 93 rotates clockwise, and the sun gear 92 of the planetary gear mechanism rotates counterclockwise.
The internal gear 111 does not rotate, and as the sun gear 92 rotates, the planetary gear 91 rotates in a clockwise direction and revolves counterclockwise, so the output member 50 starts rotating counterclockwise.

When the output member 50 starts rotating counterclockwise, the mode member 6 moves to the right in the figure via the connecting arm 49. Along with this, tape loading drive units 4A and 4B
The cam followers 4Ac and 4Bc are regulated by the unloading parts 6Aa and 6Ba of the groove cams 6A and 6B due to the urging force of the elastic parts JA'5A and 5B in the direction of the tape loading force. The tape loading section +4'lA, IB is pulled out from inside the cassette mouse and driven in the tape loading direction along the guide grooves 2A, 2B.

In the middle of this tape loading, the brake release part
is in the same one-sided pressure contact position as in the stopped state, so only the T reel 25B is braked. In addition, the tension arm 16 has its cam follower 16D regulated by the release part 6Ad of the groove cam 6A until the tape loading is completed, and the band brake 18 is in a relaxed state. There is no added tension.

Therefore, by the movement of the tape loading members IA and IB in the tape loading direction, the tape 100 applied thereto is pulled forward, and the S reel 25A to which no brake or pack tension is applied rotates slightly, and from this S reel 25A. The tape 100 is smoothly pulled out.

In addition, as the mode member 6 moves to the right, the pinch arm 8 moves its cam follower 8C forward in the direction of the Tebrode ink while being regulated by the unloading portion 6Cb of the groove cam 6C due to the biasing force of the elastic member 10. Rotate. Along with this operation, the pinch roller 9 and tape guide 12
moves forward in the tape loading direction.

Further, as the tape loading drive members 4A and 4B rotate in the tape loading direction, the left tape guide support member 13 has its regulated portion 13b pressed by the regulation pin 4Ad of the tape loading drive member 4A, and the elastic member It is rotated in the tape loading direction against the urging force of 15 in the unloading direction.

■Tape loading completed state (pause state)...Fig. 5, Fig. 15, Fig. 20, Fig. 21, Fig. 28 Mode When the member 6 has moved to the pose position as shown in Fig. 15, Tape loading drive unit 4A, 4
B and the tape loading members 1A, IB have reached the front tape loading position, and the tape loading parts tr)IIA, IB wind the tape 100 pulled out from the S reel 25A around the rotating drum 3, and the tape loading members 2C , 2D. The pressing force in this case is given by the urging force of the elastic members 5A, 5B that have driven the tape loading members IA, 1B to the tape loading position.

In this state, the cam follower 8C of the pinch arm 8 is
The pinch roller 9 is regulated by the separating portion 6Ca of the grooved cam 6C, and the pinch roller 9 is held at the separating position slightly before it comes into pressure contact with the capstan 11.

On the other hand, the left tape guide support member is held at a tape loading position corresponding to the tape loading position of the left tape loading drive member 4A.

Then, at the same time as the tape loading is completed, as shown in FIG.
To reach this point, the brake release member 3 is in the both-side pressure contact position and holds the reel brake 35 in the both-side pressure contact position.

That is, the left and right brake pads 36A, 36B of the reel brake 35 are connected to the corresponding reels 25A, 25B.
(pause state). In this case, in actual operation, the tape loading members IA, IB come into pressure contact with the position regulating parts 2C, 2D, and after a blink, the brake pads 36A, 36B come into pressure contact.

In addition, in such a pause state upon completion of tape loading, the FF idler drive anno. 127 and the preload 46 operate as shown in FIG. 20 or 21.
It continues to be in the same position from the stop state. That is,
Since the FF idler drive foot 27 is in the locked position, the F
The F idler gear 29 meshes with and locks the friction mechanism 30, and is directly connected to the pulley 34.
It is in a state where it can be transmitted to the reel 25A or T-reel 25B side. Further, the preload 46 is at the release position because its cam follower 46C is located at the release portion 6Ea of the cam E.

■Pause state → F'F'/REW mode...Fig. 28 → Fig. 30 - Fig. 29 Fig. 15, Fig. 20, Fig. 21 Next, FF/REW from the pause state shown in Fig. 28 When moving to the mode, it is necessary to release the brake pads 36A and 36B on both sides that are in pressure contact in the pause state. In this case, in this embodiment, the mode member 6 in the fast winding/pause position as shown in FIG.
After moving the brake to the reverse play position as shown in the figure and releasing the brake, and holding the brake release member 39 in the release position by energizing the plunger 45, the mode member 6 is moved again.
By returning to the fast winding/pause position, it is possible to shift to the PF/REW state as shown in FIG.

That is, if the power motor is further rotated from the state shown in FIG. 28, the output member 50 is rotated counterclockwise, and the mode member 6 is moved to the reverse play position as shown in FIG. 30, the brake can be released. Since the cam follower 39B of the member 39 reaches the release part 6De of the cam hole 6D,
The brake release member 39 moves to the release position, and the elastic member 4
0 and hold the reel brake 35 in the release position. Therefore, the brake pads 36A and 36B on both sides are separated from the reels 25A and 25B, respectively.

Further, in this state, since the plunger core 41 is in contact with the plunger 45, the plunger core 41 is attracted by energizing the plunger 45, and thereby the brake release member 39 is released via the plunger arm 42. It is held in the release position by the plunger 45.

After this, the power motor is reversed and the output member 50
Rotate clockwise to return the mode member 6 to the early spring/pause position again. As a result, as shown in FIG. 29, the brake release member 39 is held in the release position only by the attraction force of the plunger 45. In this case, the FF idler gear 29 is released from the friction mechanism 30 because the mode member 6 moves to the reverse play position and the FF idler drive foot 27 cam follower 27C moves to the release part 6Db of the cam hole 6D. However, when the mode member 6 returns to the early spring/pause position again, the cam follower 27C moves to the cam hole 6 again.
Since the reel is moved to the locking distance of D by 6 Da, the reel is again engaged with the friction mechanism 30 as shown in FIG. 29, and the reel can be rotated at high speed with strong torque. Therefore,
In this state, the FF/REW mode can be performed by rotating the reel drive motor at high speed. Also,
To exit FF/REW mode, press FF/REW.
If the plunger 45 is de-energized during the mode,
The brake pads 36A and 36B on both sides can be brought into pressure contact instantly, and the tape can be instantly stopped and returned to the pause state from the FF/REV state without tape slack or overrun.

Note that the FF/REW mode is performed by high-speed rotation of the reel drive motor, and the FF mode and REW mode in this case are
The W mode is selected by selecting the high speed rotation direction of the reel drive motor. That is, the pulley 34 rotates in one direction depending on the rotational direction of the reel drive motor, and the friction mechanism 30 rotates depending on this rotational direction. Then, according to the rotational direction of the friction mechanism 30, the swing arm 32 is rotated in the rotational direction of the friction mechanism 30 by the friction torque generated by the plate spring 33, and the idler gear 31 is rotated to the T reel 25B or the S reel 25A.
meshes with 1 As a result, the high-speed rotational force from the reel drive motor is transmitted to the T reel 25B or the S reel 2 via the pulley 34, friction mechanism 30, and idler gear 31.
5A, FF mode (Fig. 20) or REW
A moto (Figure 21) is performed.

More specifically, when the pulley 34 rotates counterclockwise due to the rotation of the reel drive motor, the friction mechanism 30
The drive gear 30A rotates clockwise, and the swing arm 32
rotates clockwise. Along with this, the idler gear 31
meshes with the T-reel 25B while rotating counterclockwise, and rotates the T-reel 25B clockwise to release the tape 100.
Wind up at high speed. This is the FF mode (Fig. 20).

Further, when the pulley 34 rotates clockwise due to the rotation of the reel drive motor, the drive gear 30A of the friction mechanism 30 rotates counterclockwise, and the swing arm 32 rotates counterclockwise. Accordingly, the idler gear 31 rotates clockwise and meshes with the S reel 25A, rotates the S reel 25A counterclockwise, and rewinds the tape 100 at high speed. This is the REW mode (FIG. 21).

In addition, in the FF mode or REW mode, the reel drive motor that also serves as the capstan motor rotates at high speed as described above, but the tape speed is further controlled by detecting the rotation of both reels and applying a servo. are doing.

■Reverse play mode: The power motor rotates further from the fast winding/pause position as shown in Figures 6, 16, 22, 30 and 15, and the output member 50 is rotated counterclockwise. When rotated,
The mode member 6 moves to the reverse play position as shown in FIG. In this state, the tape loading drive member 4A.

Cam followers 4Ac and 4Bc of 4B are groove cams 6A.

The unloading parts 6Aa and 6Ba of 6B are unregulated, and the tape loading drive parts 4A and 4B and tape loading members IA and 1B are in the pause state and FF/
As in the REW state, it is maintained in the forward tape loading position.

- The binding arm 8 is gradually released from the restricted state by the movement of the opening part 6Ca of the grooved cam 6C, and when the mode member 6 moves to the reverse play position, the biasing force of the elastic member 10 is applied. , the pinch roller 9 is rotated to the forward pressure contact position, and the pinch roller 9 is pressed against the capstan shaft 11 .

Further, as shown in FIG. 22, the tension arm 16 has its cam follower 16D in the pause state, FF/RE
Similar to the W state, the release portion 6A of the groove cam 6A of the mode member 6
d, the band brake 18 is in the release position on the left side, and therefore the band brake 18 is also kept in a loosened state away from the disc 25Aa of the S reel 25A, so that the S reel 25A can be wound. It becomes.

On the other hand, as shown in FIG. 22, the Brirod 46 is
When the mode member 6 moves to the perspective play position, its cam follower 46C enters the tension portion 6Eb of the cam 6E of the mode member 6, so it is rotated to the left tension position by the urging force of the elastic member 47, and the T reel 25B is rotated to the left tension position. The felt 46B is pressed against the disk 25Ba, and the T reel 25
A soft brake is applied to B, that is, pack tension is applied when the tape 100 runs in reverse.

Further, the operation of the brake release unit 39 is as described above in the explanation of the FF/REW mode.

That is, as shown in FIG. 30, when the mode member 6 moves to the reverse play position, the cam follower 39B of the brake release member 39 reaches the release part 6De of the cam hole 6D of the mode member 6, so the brake release member 39 is released. position and against the elastic member 40, the reel brake 3
5 in the release position. Therefore, the brake pads 36A and 36B on both sides are separated from the reels 25A and 25B, respectively.

Furthermore, since the cam follower 27C of the FF idler drive arm 27 moves to the release section 6Db of the mode section fA6D, the FF idler gear 29 is separated from the friction mechanism 30 against the biasing force of the elastic member 28. Yes, drive gear 30A in friction mechanism 30
It is possible to slip between the gear and the driven gear 30B.

In this state, when the reel drive motor is rotated at low speed and the capstan shaft 11 and pulley 34 are rotated clockwise, the tape 100 sandwiched between the pinch roller 9 and the capstan shaft 11 is At the same time, the drive gear 30A of the friction mechanism 30 rotates counterclockwise in accordance with the rotation of the pulley 34, and the idler gear 3
1 meshes with the S reel 25A, the S reel 25A rotates in the counterclockwise direction, and winds up the fed tape 1 100.

In this case, as described above, the friction mechanism 30
Because it is separated from the idler gear 29, the drive gear 3
0A and the driven gear 30B rotate with constant torque while slipping, and the S reel 25A rotates with the tape 10 being fed.
The tape 100 is wound up at a speed of 0 and a rotational speed matching the winding diameter.

In this reverse mode, back tension is applied to the T reel 25B by the preload 46, so
Stable tape running can be performed.

In the FF/REW mode described above, the plunger 45 is energized to hold the reel brake 35 in the release position, but in this reverse playmoto, the reel brake 35 can be held in the release position without energizing the plunger 45. This has the advantage of saving power consumption as much as possible.

■Play mode: FIGS. 7, 17, 23, and 31. When the power motor further rotates from the reverse play position as shown in FIG. 16, and the output member 50 rotates counterclockwise,
The mode member 6 moves to the play position as shown in FIG. In this state, tape loading member I
A and IB are in the front tape loading position as in the reverse play state, and the pinch roller 9 is also in the front pressure contact position as in the reverse play state.

Furthermore, as shown in FIG. 31, the reel brake 35 is also in the forward release position, similar to the reverse play state.
Brake pads 36A and 36B on both sides are on both reels 25A
, 25B.

On the other hand, since the FF idler gear 29 is also released from the friction mechanism 30 as shown in FIG. 23, the rotational force of the pulley 34 is transmitted via the friction mechanism 30.

In contrast, the preload 46
C is rotated to the released state by the release portion 6Ec of the cam 6E of the mode member 6, the back tension applied to the T-reel 25B is released, and the T-reel 25B can be wound with a light torque.

The tension arm 16 also has a cam follower 46
Since C moves to the tension control part 6Ac of the grooved cam 6A of the mode member 6, it is rotated to the right tension control position by the biasing force of the elastic member 19 for the first time at this position, and the band brake is applied to the disc 25Aa of the S gill 25A. 18 are brought into pressure contact, and the state is such that tension can be applied.

In this state, when the reel drive motor is rotated at a low speed and the capstan shaft 11 and pulley 34 are rotated counterclockwise, the pinch roller 9 and the capstan shaft 11 are rotated.
The tape 100 sandwiched between the capstan shaft 11 is fed forward at a tape speed corresponding to the rotation of the capstan shaft 11. At the same time, the friction mechanism 3
The drive gear 30A of No. 0 rotates clockwise, the idler gear 31 meshes with the T reel 25B, the T reel 25B rotates clockwise, and winds up the tape 100 being fed. In this case, the tape is wound through the slip of the friction mechanism 30, similar to the reverse play mode described above.
The tape 100 is wound up at a speed of 00 and a number of rotations according to the winding diameter.

When the tape 100 is fed in the forward direction, the band brake 18 applied to the S reel 25A causes the tape 100 to
Tension is applied to push back the tension post 16A provided on the tension arm 16, rotate the tension arm 16 counterclockwise (to the left), and loosen the band brake 18. Tape tension to loosen this band brake 18 and S reel 25A of band brake 18
Due to the balance of tension, S reel 25A
The tape back tension is controlled to minimize changes in tape back tension due to changes in the amount of tape remaining, allowing for stable tape running.

Note that in such a play mode as well, as in the reverse play mode, the reel brake 35 can be maintained in the release position without energizing the plunger 45, so there is an advantage that power consumption can be saved as much as possible.

■Tape unloading mode...Figure 5 - Figure 4, Figure 15 - Figure 14, Figure 20 (Figure 21) → Figure 19, Figure 28 → Figure 27. By reversing the motor and rotating the output member 50 clockwise,
Return the mode member 6 to the instep/bottom position. After this, the reel drive motor is rotated at low speed, and the pulley 34
By rotating clockwise, the swing arm 32 is rotated toward the S reel 25A, the motor torque is changed to an appropriate state, and the power motor is rotated while tape winding is performed to output the output member. By further rotating clockwise, the mode section vI6 is moved to the left (toward the stop position).
and unload the tape.

The mode member 6 is? When the brake release member 39 starts moving to the left from the winding/pause position, the cam follower 29B of the brake release member 39 first rides on the one-side release portion 6Dc of the cam hole 6D of the mode member 6, and comes into pressure contact with the S reel 25A. Release the brake pad 36A.

Following this, tape loading drive unit 4A, 4B
The cam followers 4Ac, 4Bc ride on the unloading parts 6Aa, 6Ba of the grooved cams 6A, 6B, and rotate in the unloading direction against the force f=J of the elastic members 5A, 5B in the tape loading direction. The tape loading members IA, 1B are housed in the cassette mouth along the guide grooves 2A, 2B provided in the chassis.

As the left tape loading drive member 4A moves in the tape unloading direction, the tape guide 14
is gradually released from its positional restriction, rotates in the tape unloading direction by the biasing force of the elastic member 15 that biases the tape guide support portion 13, and is housed in the cassette mouth.

In addition, the pinch arm 8 also has its cam follower 8C riding on the unloading part 6Cb of the grooved cam 6C, and resists the (=J force) of the elastic member 10 at almost the same timing as the unloading operation of the tape loading drive members 4A and 4B. The tape is then rotated in the tape unloading direction and stored in the cassette mouth.

In the middle of this tape unloading, the planetary gear mechanism changes from the instep 0 winding/pause position as shown in FIG. 5 to the cassette loading position as shown in FIG. rllll is maintained in a state in which the stopper pin 95B is completely fitted into the regulating groove 111B, thereby being held at a predetermined cassette loading position. Further, at the cassette loading position shown in FIG. 4, the output member 50 has reached the end of its outer peripheral surface that contacts the slope of the regulation groove 50B (the riding position during cassette loading).

■Cassette unloading mode (and drive switching)...Figure 4 → Figure 3 - Section 2, Figure 10 → Figure 9 → Figure 8, Figure 13 → Figure 12 → Figure 11 (Figure 10 → Figure 9 → Figure 8) (Fig. 14, Fig. 19, Fig. 27) Furthermore, when the power motor rotates at the cassette loading completion position as shown in Fig. 4, and the output member 50 further rotates clockwise, the planetary gear mechanism Start switching the drive in the opposite direction. That is, since the stopper pin 95A reaches the inclined part of the regulation groove 50B of the output member 50, the stopper plate 95 becomes rotatable, and the stopper pin 95B on the opposite side reaches the internal gear A11.
The stopper plate 95 rotates counterclockwise by being pressed by the inclined portion of the No. 11 regulation groove 111B, and as the output member 50 continues to rotate, the stopper pin 95A fits into the regulation groove 50B of the output member 50. At the same time, stopper pin 9
5B can be mounted on the outer circumferential surface from the inclined part of the regulating groove 111B of the internal gear 111, so the internal gear 111 becomes rotatable and starts rotating in the counterclockwise X1 direction.

As a result of such switching operation, as shown in FIG. 3, the output member 50 is at the most clockwise rotational position (
Tape unloading position), internal gear 1
11, the stopper pin 95B is completely mounted on its outer circumferential surface.
By lifting it up, it becomes rotatable and the drive switching is completed. Note that due to this switching operation, the output member 50 rotates slightly and the second drive roller 50A also moves slightly, but this movement is similar to the switching operation during cassette loading described above, and is similar to that shown in FIGS. As shown in FIG. 4, the connecting arm 49 is not moved because it is carried out within the recess of the groove 49B of the connecting arm 49.
The configuration on the tape loading mechanism side is maintained in the above-mentioned stopped state.

After this switching operation, when the power motor further rotates, the final gear 93 rotates counterclockwise, and the sun gear 92 of the planetary gear mechanism rotates clockwise, the output member 50 does not rotate and the sun gear 92 rotates. According to the rotation, the planetary gear 91 rotates counterclockwise on the spot, and the internal gear 111 starts rotating in the counterclockwise direction.

As the internal gear 111 rotates, its drive pin (cassette loading drive unit) 111C starts moving forward, so that the cam plate 101 engaged with the drive pin 111C also moves backward as shown in FIGS. 10 and 13. Start moving forward from the cassette loading position and start cassette unloading.

Then, as the cam play 1-101 moves forward, the cam roller 107A of the right holder arm 107 starts to rise along the lifting slope 101Ab of the cam 101A of the cam play 1-101, and accordingly, the cassette holder 11
The cassette begins its 0-movement to the cassette loading position.

This operation corresponds to the lowering operation of the cassette holder 110 in the aforementioned cassette loading, and is performed by the movement stroke of the cam plate 101 relative to the sub-plate 1-102. -101 and subplate 1
02 is in an extended state,
Since the subplate 102 is biased rearward, the subplate 102, guide arm 103, and cassette guide 104 are held in the suction position by this biasing force.

Furthermore, the internal gear 111 rotates counterclockwise, and as shown in FIGS.
From the lifting slope part 101Ab of A to the holding horizontal part 101A
When the cassette holder 110 rises to the cassette raised position, the engaging protrusion 101B of the cam plate 101 comes into contact with the rear end of the sub-plate 102.

Therefore, from this point on, the power motor is rotated further,
By rotating the internal gear 111 counterclockwise,
The cam play 1-101 and the sub play 102 advance together, and with this forward movement, the guide arm 103
When the elastic member 113 urges one end of the engaging roller 103A side forward, the cassette guide 104 starts to rotate counterclockwise, and the cassette guide 104 moves from the cassette suction position at the front to the cassette unloading position at the rear. Start moving.

Finally, the internal gear 111 is
When the most counterclockwise rotational position (cassette unloading position) is reached as shown in , the cassette guide 1
04 reaches the cassette unloading position as shown in FIG. 8, and the cassette is ejected. In this case, as the sub-plate 102 moves forward, a cassette eject detection switch (not shown) is turned off, it is determined that ejection has been completed, and the power motor is stopped.

Effects of this embodiment* As explained in -1- below, in this embodiment, the cassette The loading mechanism and tape loading mechanism can be switched and driven as appropriate. In other words, there is no need to use separate drive motors for each mechanism as in the past, and one drive motor (power motor) can drive both the cassette loading mechanism and the tape loading mechanism. The number of drive motors can be reduced. Furthermore, since switching between cassette loading and tape loading is performed mechanically, there is an advantage that a cassette loading completion switch can be omitted. Therefore, it is possible to contribute to the miniaturization and simplification of the entire magnetic recording/reproducing device.

In addition, in this embodiment, the same mode member 6 not only drives and positions the tape loading mechanism, but also drives and positions a plurality of mechanisms including a tension control mechanism, a friction mechanism, a transmission torque switching mechanism, and a brake mechanism. Since it is configured to perform control at the same time, 1
Loading/unloading of cassettes, loading/unloading of tapes, and
It is possible to perform all of the unloading and mode switching of the plurality of mechanisms, and can further contribute to the miniaturization and simplification of the entire magnetic recording and reproducing apparatus.

Furthermore, in this embodiment, when driving the cassette loading mechanism, the power plate 101 and the sub-player 1-102 are connected by an elastic member 112, and the cassette holder 110 and the cassette guide 104 are individually driven. Therefore, the driving operation strokes can be overlapped. Therefore, it is possible to contribute to reducing the operating space of the entire mechanism. In addition, the elastic member 1
12 performs the stroke absorbing function of the cassette guide 104, which has the advantage of simplifying the configuration by eliminating the need for a dedicated stroke absorbing mechanism.

*Other Examples* Note that the present invention is not limited to the above-mentioned Examples,
Contrary to the above embodiment, a configuration in which the output member is provided with a cassette loading drive section and the internal gear is provided with a tape loading drive section is also possible, and similar effects can be obtained.

Further, the specific shape and arrangement configuration of each member can be selected as appropriate, for example, the configuration of a position regulating member that regulates the rotational position of the internal gear or output member and a non-regulating portion on the internal gear or output member side. can be selected as appropriate.

Further, in the present invention, although the mechanism to be subjected to mode switching can be selected as appropriate, the present invention is equally applicable to a tape loading mechanism that does not have a moto switching function.

[Effects of the Invention] As explained above, in the present invention, by using a planetary gear mechanism, the driving force of the same drive motor can be
Since the transmission can be selectively transmitted to either the cassette loading mechanism side or the tape loading mechanism side, the same drive motor can now drive both the cassette loading mechanism and the tape loading mechanism, which were previously driven separately. It is possible to provide an excellent cassette loading and tape loading drive mechanism that can reduce the number of drives and contribute to downsizing and simplifying the entire device.

In addition, if the mode member is configured to drive various mechanisms and control their positions, it will further contribute to the miniaturization and simplification of the entire magnetic recording and reproducing device, and it will be possible to realize a more practical magnetic recording and reproducing device. .

Furthermore, if the cassette I/loading mechanism is constructed so that the cassette guide and cassette holder are individually driven by two plates and an elastic member, the operating space of the cassette loading mechanism can be reduced, and the cassette guide Since the stroke absorption mechanism can be omitted, the side of the cassette loading machine itself can be made smaller and simpler.
