Abstract

PURPOSE:To attain an ejection lever mechanism having high operability by moving back a guide arm to a sucking position in a cassette ejection mode with an ejection lever and an ejection plate kept stationary at the inner positions. CONSTITUTION:When an FF lever 2, for example, is pressed, a taper pressing part 4 presses a pin 7 set at a relief plate 6. This prevents the cassette ejecting action of an ejection plate 1. Instead only an FF or REW action is carried out with the push of an FF or REW lever 2 or 3. When both levers 2 and 3 are pushed at a time, the pressing parts 4 and 5 become V-shapes to push the pin 7 from both sides. Thus the plate 6 is unable to have rotation and moves to the inner side of a tape player together with the plate 1. Then a guide arm 11 interlocking an ejection plate 8 is turned toward the inner side to compress a reaction spring 14 and to shift the fulcrum at the guide arm side to the inner side. As a result, the repulsive power of the spring 14 is applied at the front side of the tape player and push a back stopper 13 forward to eject a cassette.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an eject lever mechanism for ejecting a cassette mounted at a playback position in a cassette tape player.

[Technical background of the invention and its problems] Fast forward (hereinafter referred to as FF) lever and rewind (hereinafter referred to as RE)
In the eject lever mechanism of the type that ejects the cassette when the lever (referred to as W) is pushed in at the same time,
Conventionally, the lever pullout position was the same when the cassette was installed and when it was not installed. As a result, the lever at the front gets in the way when installing a cassette, resulting in poor operating performance.

Also, when selling or transporting a tape player, if the lever is protruded toward the front without a cassette installed, the lever will protrude from the front of the escutcheon, causing the lever to get in the way and look unsightly, or cause the lever to protrude. Other objects may get caught on the lever, causing damage to the lever.

Furthermore, since it is not possible to determine whether a cassette is installed or not by simply looking at the position of the lever, you cannot tell whether a cassette is present or not unless you look inside the tape player through the dustproof door of the cassette insertion slot.
This method is unsuitable for tape players such as car stereos, which require the status of the tape player to be determined in a short period of time.

In order to improve this problem, it is possible to reduce the amount of protrusion of the lever, but if you do this, the amount of push of the lever will be reduced when ejecting the cassette, making it difficult to eject the cassette without malfunction. Become.

[Object of the Invention] The present invention was proposed in order to solve the problems of the prior art as described above.The purpose of the present invention is to locate the tape player at the back of the tape player when the cassette is not installed, and to place the cassette at the back of the tape player when the cassette is installed. To provide an eject lever mechanism configured to be located at the front.

Summary of the Invention The eject lever mechanism of the present invention includes an FF lever and a REW lever.
The levers are formed with tapered pressing parts that form a V-shape when the levers are overlapped in opposite directions, and a relief plate is rotatably disposed above the eject plate, and the pin on the relief plate is connected to the FF- Fits into the tapered pressing part of the REW lever,
Furthermore, by providing an ejection plate having an engaging portion that engages with the engagement pin of the eject plate on the upper side of the relief plate, and further providing a pressing member that rotates the ejection plate in a direction to release this engagement, the cassette The position of the pull lever can be changed when the device is not installed and when it is installed.

[Embodiment of the Invention] An embodiment of the present invention will be specifically described below with reference to FIGS. 1 to 4.

In Fig. 1, an eject plate 1 that reciprocates back and forth is arranged under an FF lever 2 and an RFWFF lever 2, overlapping each other, and the FF and REW levers are arranged in opposite directions and in a V-shape when both levers overlap. Taper-shaped pressing portions 4 and 5 are formed so as to have the following shape. A relief plate 6 is rotatably disposed above the eject plate 1, and a pin 7 is pressed against the relief plate 6 by the tapered suppressing portion 4.5 of the FF and 'REw levers.
is provided. Further, above the relief plate 6, there is disposed an ejection plate 8 that reciprocates in the same direction as the eject plate 1 and moves the cassette forward. This ejection plate 8 is bored with an engagement hole 9 having a tapered engagement part 9a and a relief part on the distal end thereof, and an engagement pin 10 on the eject plate side is inserted into this engagement hole 9. It has been inserted. The ejection plate 8 also has a protrusion that rotates the ejection plate 8 in a direction to release the engagement between the engagement pin 10 and the tapered engagement portion 9a when the FF-REW lever is in the most pushed position. A pressed portion 8a is provided, and the pressed portion 8a is configured to rotate the discharge plate 8 by contacting a pressing member F provided on the base of the tape player. In addition, the discharge plate 8
A rod-shaped link 12 is disposed between the back stopper 13 and the guide arm 11, and transmits the force of a reversing spring 14 provided between the back stopper 13 and the guide arm 11 to the discharge plate 8. Furthermore, a locking mechanism 15 for locking the FF and REW levers during an eject operation is provided at the leading end in the cassette mounting direction.

The operation of the □ eject lever mechanism of this embodiment having such a configuration is as follows.

1) At the time of FF or REW, as shown in Figure 2, press either one of the levers (for example, F
When the F lever 2) is pressed, its tapered pressing portion 4 presses the pin 7 provided on the relief plate 6. However, since the escape plate 6 rotates laterally around the attachment point with the eject plate, even if the FF lever 2 is pushed in, the escape plate 6 and the eject plate 1 connected to it will not move to the back of the tape player. It never moves. Therefore, the cassette is not ejected by the eject plate, and the FF or FI operation is not performed by the FF or REW lever.
Only EW operation is performed.

2) When the cassette is ejected, as shown in FIG. 3, when both the FF and REW levers are pushed in at the same time, the tapered pressing portions 4.5 of both levers overlap in a V-shape, and the pin 7 of the relief plate 6 is pushed from both sides, so the escape plate 6 cannot rotate, but is pushed by both pressing parts and moves to the back of the tape player.

Therefore, the eject plate 1 connected to the escape plate 6 also moves to the inner part.

In this state, the play 1-1 to the ejector 1 and the ejection plate 8 are connected to the tapered engagement portion 9 by a reversing spring provided between the back stopper 13 and the guide arm 11.
Since the discharge plate 8 is biased in one direction, the discharge plate 8 moves together toward the back of the tape player while remaining in the engaged state.

When the ejection plate 8 moves to the back together with the ejection plate 1, the guide arm 11 that interlocks with the ejection plate 8 rotates to the back.
The reversing spring 14 is compressed, and the fulcrum of the reversing spring 14 on the guide arm side moves to the back of the tape player.

When the fulcrum on the guide arm side comes further back than the fulcrum on the back stopper side, the repulsive force of the reversing spring 14 acts on the front side of the tape player, pushes the back stopper 13 toward the front, and ejects the cassette toward the front.

At this time, as the fulcrum of the reversing spring 14 on the guide arm side advances to the back of the tape player, the direction of action of the reversing spring 14 on the ejecting plate 8 changes, and the engagement between the tapered engagement portion 9a of the ejecting plate 8 and the ejecting plate side changes. Matching pin 1
The force to maintain engagement with zero is lost. When the ejection plate 8 moves to the back with the eject plate on the subsequent page, the ejection plate 8 moves to the protruding pressed portion 8 near its most pushed position.
a hits the pressing portion IJF and is forcibly rotated in the opposite direction to the biasing direction of the spring. Note that this rotation is done smoothly because the force (d) of the spring is lost.
As shown in the figure, when the ejection plate 8 rotates, its tapered engagement portion 9a disengages from the engagement pin 10 on the eject plate side, and the ejection plate 8 is moved by a return spring (not shown). ) allows it to move forward as described above. As a result, the back stopper 13 and the guide arm 11 move forward as the cassette is ejected, and the ejection plate 8 also moves forward.

On the other hand, the eject plate 1 that has been pushed in is locked at its most pushed position by the lock mechanism 15, which operates only after the cassette is ejected.

As a result, the F that engages with the eject plate through the elongated hole
The F-REW lever is also prevented from returning to the front side and is locked at the pushed-in position.

3) Attaching the cassette When the cassette is inserted into the deep player, the locking mechanism 15 moves under pressure from the cassette and unlocks the extract plate 1. Then, the eject plate 1 moves forward by the force of the return spring (not shown), and as a result, the eject plate 1 moves forward, and the FF, which was locked at the back of the tape player by the eject plate, moves toward the front.
-, , R, E, W levers also move toward you. As a result, when the cassette is completely installed, the FF-REW lever is in a more protruding state than when it is not installed.

In addition, when the back stopper 13 moves to the back as the cassette is installed, and the fulcrum on the back stopper side of the reversing spring 14 becomes further back than the fulcrum on the guide arm side, the force of the reversing spring 140 is applied to the guide arm 11 and the rod-like link 1.
2 to the ejection plate 8 and urges the ejection plate 8, the ejection plate 1 returns to the front and its engagement pin 10 reaches the position of the tapered engagement portion 9a of the ejection plate 8. Then, the ejecting plate 8 rotates, and both engaging portions engage with each other, so that the ejecting plate 1 and the ejecting plate 8 can be simultaneously moved to the back during the next ejection. (Return to the state shown in FIG. 1) As described above, the present invention includes a relief plate rotatably attached to the eject plate and an FF that presses the relief plate.
- A simple configuration with an ejection plate that moves forward together with the REW lever and eject plate, and after the eject plate is locked at the back, separates from the eject plate and moves forward independently, allows the tape to be removed when a cassette is not installed. It is possible to obtain an eject lever mechanism that is located at the back of the player and is positioned at the front when a cassette is installed. Further, since the reversing spring disposed on the guide arm is used as the spring for maintaining the engagement between the eject plate 1 and the ejection plate 8, there is no need to add new members.

Furthermore, since this spring ensures that the engagement pin 10 of the eject plate is engaged with the tapered engagement portion 9a of the ejection plate 8, there is no problem that only the eject plate is pushed in during ejection, and the operation is smooth. become certain.

Also, release the engagement between the eject plate and the discharge plate, □
Since this is forcibly performed by the pressing member F near the most pushed-in position, the ejecting plate 8 is not left behind together with the ejecting plate 1, and the cassette can be reliably ejected.

Note that the present invention is not limited to the above-described embodiments, and instead of using a reversing spring as a spring for maintaining engagement between the eject plate and the discharge plate, a dedicated spring may be used. Further, a pressing member for forcibly rotating the discharge plate at the most pushed-in position may be provided at another position. Furthermore, the engagement hole having the tapered engagement part may not be provided in the discharge plate, and the engagement part may be provided at the edge of the discharge plate.

[Effects of the Invention] As explained above, according to the eject lever mechanism of the present invention, a relief plate is rotatably attached to the eject lever, and an F[・REW lever that presses a pin on the relief plate,
and the eject lever, and after the eject plate is locked in the push-in position, an eject plate is provided that moves forward independently away from the eject plate, so that when no cassette is loaded, □ is located at the back of the tape player. It is possible to provide an eject lever mm with high operability, which can be located at the front when a cassette is installed.

Detailed Description of the Invention [Technical Field of the Invention] The present invention relates to an eject mechanism for ejecting a cassette installed at a playback position in a cassette tape player. [Technical background of the invention and its problems] Conventionally, eject mechanisms for tape players have been of the type in which the turret is ejected via the eject plate when the fast-forward and rewind levers are pushed in at the same time; Even if the eject lever is provided independently 9
Furthermore, there are devices in which the eject plate is also used as an eject lever, but in any case, the lever pullout position is the same when the cassette is installed and when it is not installed. If the lever protrudes from the front of the chassis when cassette 1 is not installed,
The disadvantage was that the lever at the front got in the way when installing the cassette, making it difficult to operate. Furthermore, when transporting the tape player, other objects may get caught on the protruding lever, causing damage to the lever, and when the tape player A2 is being sold, the lever gets in the way and looks unsightly. Furthermore, since it is not possible to determine whether a cassette is installed or not by simply looking at the position of the lever, you cannot tell whether a cassette is present or not unless you look inside the tape player through the dustproof door of the cassette insertion slot.
This method is unsuitable for tape players such as car stereos, which require the status of the tape player to be determined in a short period of time. Therefore, in a tape player, the eject lever only protrudes toward the front when it is installed, and when it is not installed,
It is desirable to adopt a two-stage system located at the back of the tape player. However, if such a two-stage system is adopted for the adjustment mechanism using the reversing spring 20 as shown in FIGS. 5 to 7, the following problems will occur. That is, the reversing spring 20 is provided between the back stopper 21 that supports the cassette and the guide arm 22, and as shown in FIG. When the back stopper 21 is in front of the fulcrum, the back stopper 21 is biased toward the front, and the fulcrum on the pax 1 to collar 21 side of the reversing spring 20 is aligned with the fulcrum on the guide arm 22 side, as shown in FIG. When moving to the reverse position and moving to the back, back stopper 2
1 is biased towards the back side. In the loading operation, as shown in FIG. 5, when the Pax 1 header 21 and the guide arm 22 are in the front position, the cassette is inserted against the biasing force of the reversing spring 20, and the back stopper 21 is This is done by moving the reversing spring 20 to the rear side.If the reversing spring 20 is rotated manually or by driving force, etc. from the reversing position shown in FIG. The biasing force moves the back stopper 21 to the cassette mounting position as shown in FIG. In addition, the ejecting operation is performed by pressing the eject plate 24, which also serves as an eject lever, which is connected to the guide arm 22 by a rod-shaped link 23, and moves the guide arm 22 as indicated by the chain line in the figure. As shown, by rotating the reversing spring 20 toward the back and positioning the fulcrum on the guide arm 22 side of the reversing spring 20 further back than the fulcrum on the back stopper 21 side, the biasing force of the reversing spring 20 is reversed, and the back stopper 21 returns to the front. At this time, the eject plate 24
5 returns to the front again, so the guide arm 2
2 also returns to the front, returning to the state shown in FIG. 5 before the cassette was installed. In the above configuration, if the eject plate 24 is held at the back position when the cassette is ejected,
The guide arm 22 stops at the back position, making it impossible to eject the cassette. Therefore, it is necessary to return the guide arm 22 to the front position while the eject plate 24 is stopped at the rear position so that the cassette can be ejected. In this case, the reversing spring 2
If the length 0 is made longer, the guide arm 22 returns to the front, but in this case, the suction operation of the guide arm 22 becomes impossible, and therefore, it is not possible to adopt a means of changing the length of the reversing spring 20. Further, such a drawback also exists in tape players of a type that has an independent eject lever or a type of tape player that uses an FF-REW lever as an eject lever. Therefore, it is difficult to position the eject lever and the eject plate toward the back when they are not installed. On the other hand, it is possible to consider a method of reducing the amount of protrusion of the lever when the cassette is not installed, but in that case, the amount of push of the lever when ejecting the cassette will be reduced, and □
A new problem arises in that malfunctions are likely to occur during cassette ejection. [Object of the Invention] The present invention was proposed in order to solve the above-mentioned drawbacks of the prior art, and its purpose is to prevent the eject lever and eject plate from remaining at the rear position when ejecting a cassette. Another object of the present invention is to provide an eject mechanism configured so that the guide arm can be returned to the suction position, so that it protrudes toward the front when the device is attached, and is located at the back when the device is not attached. [Summary of the Invention] The ejecting mechanism of the present invention is a tape player in which a back stopper and a guide arm are connected by a reversing spring, and the ejecting mechanism includes an ejecting plate having an engaging portion that engages with an engaging member of the ejecting plate. an engagement spring that connects the ejection plate to the guide arm and maintains the engagement between the ejection plate and the eject plate; and further rotates the ejection plate in a direction to release the ejection plate from the ejection plate. By providing a pressing member, the positions of the eject plate and the eject lever can be changed when the cassette is not installed and when the cassette is installed. [Embodiments of the Invention] = 7 - Hereinafter, one embodiment of the present invention in which the present invention is applied to an eject lever mechanism that covers an FF-REW lever with an eject lever will be described in detail with reference to FIGS. 1 to 4. In Fig. 1, an FF lever 2 and a REW lever 3 are arranged vertically and overlappingly under the control plate 1 that reciprocates back and forth, and the FF lever 2 and the REW lever 3 are arranged in opposite directions and both levers. Tapered pressing parts 4 and 5 are formed so as to form a V-shape when they overlap.A relief plate 6 is rotatably disposed on the upper side of the eject plate 1. A pin 7 is provided on the plate 6 to be pressed against the tapered pressing portions 4 and 5 of the FF and REW levers.Furthermore, on the upper side of the escape plate 6,
An ejection plate 8 is provided which reciprocates in the same direction as the ejection plate 1 and moves the cassette forward. This discharge plate 8 is bored with an engagement hole 9 having a tapered engagement part 9a and a relief part on the distal end thereof. A dowel pin 10 is inserted. Further, the ejection plate 8 is provided with the engagement pin 10 and the tapered engagement portion 9a at the most pushed position of the FF-REW lever.
A protruding suppressed part 8a is provided to rotate the ejecting plate 8 in a direction to release the engagement with the tape player, and this suppressed part 8a comes into contact with a suppressing member F provided on the base of the tape player to eject the tape. It is configured to rotate the plate 8. Further, a rod-shaped link 12 is disposed between the discharge plate 8 and the guide arm 11, and transmits the force of the reversing spring 14 provided between the pax 1 to the collar 13 and the guide arm 11 to the discharge plate 8. ing. Furthermore, a locking mechanism 15 is provided at the leading end in the cassette mounting direction for locking the FF and REW levers during an eject operation. The operation of the eject lever mechanism of this embodiment having such a configuration is as follows. 1) At the time of FF or REW, as shown in Figure 2, press either one of the levers (for example, F
When the F lever 2) is pressed, its tapered pressing portion 4 presses the pin 7 provided on the escape plate 6. However, since the relief plate 6 is attached to the eject plate by rotating laterally around the part, even if the FF lever 2 is pushed in, the relief plate 6
And the eject plate 1 connected thereto does not move to the back of the tape player. Therefore, the cassette is not ejected by the eject plate, and only the FF or REW operation is performed by the pressed FF or REW lever. 2) When cassette i is ejected, as shown in FIG. Since the pin 7 is pushed from both sides, the relief plate 6 cannot be rotated, but is pushed by both pressing parts and moved to the back of the tape player. Therefore, the eject plate 1 connected to the escape plate 6 also moves to the inner part. In this state, the eject plate 1 and the eject plate 8 are
Since the discharge plate 8 is biased in the direction in which the tapered engaging portion 9a and the engaging pin 10 are engaged by the reversing spring provided between the back stopper 13 and the guide arm 11, the engaged state Move together toward the back of the tape player. When the ejection plate 8 moves to the back together with the ejection plate 1, the guide arm 11 that interlocks with the ejection plate 8 rotates to the back.
The reversing spring 14 is compressed, and the fulcrum of the reversing spring 14 on the guide arm side moves to the back of the tape player. When the fulcrum on the guide arm side comes further back than the fulcrum on the back stopper side, the repulsive force of the reversal spring 14 acts on the front side of the tape player, pushes the back stopper 13 toward the front, and ejects the cassette toward the front. At this time, as the fulcrum of the reversing spring 14 on the guide arm side advances to the back of the tape player, the direction of action of the reversing spring 14 on the ejecting plate 8 changes, and the engagement between the tapered engaging portion 9a of the ejecting plate 8 and the ejecting plate side changes. Matching pin 10
The force required to maintain the engagement is lost. When the ejection plate 8 moves to the back with the eject plate on the subsequent page, the ejection plate 8 moves to the protruding pressed portion 8a near its most pushed position.
hits the pressing member F and is forcibly rotated in the opposite direction to the biasing direction of the spring. Note that this rotation is performed smoothly since the biasing force of the spring is lost. As shown in FIG. 4, when the discharge plate 8 rotates, its tapered engagement portion 9
A is disengaged from the engagement pin 10 on the eject plate side, and the ejection plate 8 can be moved forward as described above by the force of the return spring (not shown). As a result, the discharge plate 8 also moves forward together with the back stopper 13 and the guide arm 11, which move forward with the discharged cassette. On the other hand, the eject plate 1 that has been pushed in is locked at its most pushed position by the lock mechanism 15, which operates only after the cassette is ejected. As a result, the F that engages with the eject plate through the elongated hole
The F-REW lever is also prevented from returning to the front side and is locked at the pushed-in position. 3) Attaching the cassette When the cassette is inserted into the tape player, the locking mechanism 15 moves under pressure from the cassette and unlocks the eject plays 1-1. 1-rudo, = 12
- The eject plate 1 is moved forward by the force of its return spring (not shown), and as a result, the eject plate 1 is locked at the back of the tape player.
The F-REW lever also moves toward you. As a result, when the cassette is completely installed, the FF-REW lever is in a more protruding state than when it is not installed. In addition, when the back stopper 13 moves to the back as the cassette is installed, and the fulcrum on the back stopper side of the reversing spring 14 becomes further back than the fulcrum on the guide arm side, the force of the reversing spring 14 is applied to the guide arm 11 and the rod-shaped link. 12 to the ejection plate 8 and urges the ejection plate 8, the plate 1 returns to the front side of the ejector 1, and the engagement pin 10 moves to the position of the tapered engagement portion 9a of the ejection plate 8. When the ejection plate 8 reaches the position, the ejection plate 8 rotates and both engaging portions engage with each other, so that the ejection plates 1 to 1 and the ejection plate 8 can be moved to the rear at the same time during the next ejection. (Return to the state shown in Figure 1) Above) As mentioned above, in this embodiment, the eject plate is rotatably attached to the eject plate. Move forward and after eject play 1- is locked at the back,
The eject lever mechanism is equipped with an eject plate that moves forward independently away from the eject plate.The simple structure of [2] allows the eject lever mechanism to be located at the back of the tape player when no cassette is installed, and located at the front when a cassette is installed. can be obtained. Furthermore, since the reversing spring 14 ensures the engagement state between the engagement pin 10 of the eject plate and the tapered engagement portion 9a of the ejection plate 8, there is no inconvenience such as only the eject plate being pushed in during ejection, and the operation becomes certain. Furthermore, since the engagement between the eject plate and the ejection plate is forcibly released by the pressing member F near the most pushed position, the ejection plate 8 is not left in the back together with the eject plate 1, and the ejection plate is reliably released. The cassette can be ejected. Note that the present invention is not limited to the above-described embodiment, and instead of using a reversing spring as an engagement spring for engaging the eject plate and the ejection plate, a dedicated spring can be used. Also, a pressing member for forcibly rotating the discharge plate at the most pushed-in position may be provided at another position.Furthermore,
The engagement hole having the tapered engagement part may not be provided on the ejection plate, and the engagement part may be provided on the edge of the ejection plate.In addition, the present invention does not necessarily apply to a type in which the FF-REW lever is used as an eject lever. The present invention is not limited to the present invention, and can be similarly applied to a type having an independent eject lever or a type having a dual use as an eject plate and an eject lever.
□ [Effect of the invention] □ As explained above, according to the eject lever mechanism of the present invention, after the eject lever and the eject plate are locked at the pushed-in position, the ejection plate separates from the eject plate and moves forward independently. By arranging
When the cassette is not installed, it is located at the back of the tape player.
It is possible to provide an eject mechanism with high operability that can be positioned in front when a cassette is installed. 4.
