Abstract

PURPOSE:To simplify the insertion operation of a tape cassette by providing a blinder abutting part on a cassette in an adapter moving means, and setting a cassette insertion opening at an open state. CONSTITUTION:An adapter 50 is provided with a tape draw-out means, and draws out the tape in a small tape cassette so as to be nearly equal to the tape feed path of a large tape cassette 74. Thereby, the adapter 50 can be mounted on a tape driving mechanism 19 without disturbing the operation of the cassette 74 by a mounting means. And the mechanism 19 is moved to a left side, and the adapter 50 confronts with the tape cassette insertion opening 18 via a turning means. At this time, a part not confronting with a small tape cassette holder 23 at the insertion opening 18 is covered with a covering means, and the position of the insertion opening 18 can be easily discriminated. Also, at the insertion opening 18, a blinder 35 is abutted with the adapter 50, and the insertion opening 18 can be easily inserted by the blinder 35. The mechanism 19 is moved reciprocally, and mounting and insertion are repeated, and the cassette can be held with the cassette holder corresponding to the cassette large or small in size.

The operation of the conventional magnetic recording/reproducing apparatus configured as described above will be described below.

The small tape cassette adapter 16 is inserted into the adapter housing T located at position A in FIG. 9 from the adapter (standard type tape cassette) insertion opening 3. The adapter housing 7 into which the adapter 15 for a small tape cassette is inserted is connected between the position A shown in FIG. is driven and guided by guide grooves 12, 13, and 14, and moves through the small tape cassette storage/retrieval position C shown in FIG.

At position C, the small tape cassette insertion position of the small tape cassette adapter 15 inserted into the adapter housing 7 faces the small tape cassette insertion opening 6 of the top plate 4, so the small tape cassette is inserted at this position C. Cassettes can be replaced.

Problems to be Solved by the Invention However, with the above configuration, when a large tape cassette is installed in the device, the adapter inserted in the device must be removed from the device and stored outside the device. Furthermore, when using a small tape cassette, there was a problem in that the adapter had to be stored outside the device and then inserted into the device, resulting in poor operability.

In view of the above-mentioned problems, the present invention provides a tape drive device that has a built-in adapter for a small tape cassette for mounting a small tape cassette to the device, thereby improving operability.

Means for Solving the Problems In order to solve the above problems, the tape drive device of the present invention has the following features:
A tape cassette insertion slot into which a tape cassette is inserted; a cassette holder that holds a large tape cassette inserted from the tape cassette insertion slot; A blinder that opens and closes, a blinder rotating means that rotates the blinder, a small tape cassette holder that holds a small tape cassette inserted from a tape cassette insertion slot, and a tape in the small tape cassette that is arranged along the tape running path of the large tape cassette. an adapter having a tape drawer means for pulling out tapes equally, a mounting means for mounting either one of the adapters holding a large tape cassette or a small tape cassette on a tape drive mechanism, and a small tape cassette holder attached to a tape cassette insertion slot. means for substantially covering the portion of the tape cassette insertion slot that does not face the small tape cassette holder when facing each other;
The adapter is moved back and forth between a first position where the mounting means does not interfere with the mounting operation of the large tape cassette and a second position where the small tape cassette holder faces the tape cassette insertion slot, and the adapter is brought into contact with the blinder at the second position. , and an adapter moving means having a blinder abutting portion for opening the cassette insertion port.

Effects of the present invention With the above configuration, when a large tape cassette is installed in a device as in the conventional case, the adapter inserted in the device is detached from the device and stored outside the device.
Also, when using a small tape cassette, there is no need to insert an adapter stored outside the device into the device, and when using a standard tape cassette,
A large tape cassette can be attached to the device simply by inserting it into the cassette insertion slot, or if a small tape cassette is used, it can be easily attached to the device by inserting the small tape cassette into the adapter inside the device. Furthermore, the complexity of the mechanism for opening and closing the blinder when inserting the cassette can also be eliminated.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIG. 7 is a perspective view showing the external appearance of a one-shot example of the magnetic recording/reproducing apparatus of the present invention. This magnetic recording/reproducing apparatus 16 has a tape cassette insertion slot 18 in the front spring /L/17. 1 to 4 are incorporated into the device 16. FIGS. 1 to 3 are left side views of essential parts showing the large tape cassette mounting mechanism and the small tape cassette mounting mechanism. 6 is a side view taken from arrow A in FIG. 6. FIG.

In FIGS. 1 to 5, vertical support plates 20, 21 are arranged approximately perpendicularly to the left and right sides of the tape drive mechanism 19 of the apparatus.
A cassette holder 23 is movably provided between the two. Protrusions 24, 25 and 26 of the cassette holder 2301 pair.
27 is slidably engaged in guide grooves 28 and 29 provided in the vertical support plate 20.21. Vertical support plate 20.
A pair of drive arms 31 and 32 are press-fitted into both ends of the shaft 30 supported by the shaft 21 in the same phase, and rotate together.

The protrusion 24.25 fits into the groove 33. of the drive arm 31.32.
34 in a slidable manner.

The blinder 35 is provided immediately after the cassette insertion slot,
A pair of support shafts 36 are rotatably supported by the vertical support plate 20.21.

In Figure 4, a motor for driving the cassette (not shown)
The rod 37 moves in conjunction with the motor as the motor rotates.
The drive arm 32 meshed with the rack portion rotates about the shaft 30, and the drive arm 31 also rotates in synchronization with the shaft 30. The tip of the rack portion of the rod 37 meshes with the cam gear 38, causing the cam gear 38 to rotate. Cam part 3 of cam gear 38
9, the blind opener 41 contacts a part 42 of the blind and opens the cassette insertion opening 18 from the position indicated by the dashed line in FIG. In the open state, the large tape cassette is moved from the position where it is attached to the tape drive mechanism 19 to the position shown by the solid line, where it can be attached to and removed from the cassette holder, and to the position shown by the two-dot chain line, where there is no problem in transporting the cassette. Drive and hold the blinds. The cam gear 38, the repari, and the blind opener 41 constitute blinder rotating means.

When the drive arm 31 rotates counterclockwise in FIG. 1, the cassette holder 23 is guided by the grooves 43 and 44, and moves first horizontally and finally vertically to release the tape as shown by the dotted line in FIG. The user approaches the drive mechanism 19 and attaches a large tape cassette or a small tape cassette to the tape drive mechanism 19 as described later. A shaft 45 provided on the vertical support plate 20
A pinion 46 is attached to the foot, and when the pinion 46 rotates, an elevator 48 having a rack 47 meshing with the pinion 46 moves up and down. As shown in FIG.
Since the upper half 51 is engaged with a groove 52 provided on the side surface of the upper half 51, the rotation of the pinion 46 causes the upper half 51 to move up and down.

Similarly, a pinion 64 is attached to the shaft 63 provided on the vertical indicator plate 20.
The lower half 57 of the adapter 50 is attached to the elevator 66, which has a rack 66 that engages with the pinion 64.
is mounted, so that when the pinion 54 rotates, the elevator 56 and the lower half 67 move up and down.

The vertical support plate 21 also has the same configuration as the vertical support plate 20. Elevators 48,56 constitute adapter moving means.

FIG. 6 shows the main structure of the lower half 57 of the adapter 50 built into the device. The gear 68 rotatably supported by the lower part 767 is attached to the vertical support plate 20 shown in FIG.
When the adapter 6o moves from the state shown in FIG. 3 to the left in FIG. When moving to the right, the gear 58 rotates counterclockwise.

The internal structure of the adapter 50 is well known from the VH3 type VH8-C outlet adapter, etc., so I will not go into details, but in FIG. 6, when the gear 58 rotates clockwise, the The magnetic tape 64 is pulled out from the small tape cassette 63 by the pull-out pin 6o and the pull-out pin 62 on the rotating arm e1, and -
As shown by the dotted chain line, it is configured to form a tape loop 65 similar to the tape loose of a large tape cassect. Also, when the gear 68 rotates counterclockwise,
The rotating arm 69 and the rotating arm 61 move from the state shown by the dashed line to the state shown by the solid line and the broken line, and the tape loop is shortened, and the gear 66 moves the take-up le/L'67 in the small tape cassette 63. The magnetic tape is driven to store a magnetic tape in a small tape cassette 63.

As shown in FIG. 5, the adapter 50 has a structure that can be divided into an upper half 1-761 and a lower half 67.
The structure is such that the relative position in the horizontal direction does not shift due to the bosses 68 and 69 planted at the bottom and the shafts 0 and 71 planted at the bottom 1 and 6 ends. The upper half 51 is a small tape cassette 63
A small tape cassette holder 72 holding the tape cassette holder 72 is arranged so as to be slidable in the left-right direction in FIG. The lower half 57 includes a tape pull-out mechanism including the above-mentioned rotating arm 59.61 and pull-out pin 60.62, and a small tape cassette 63 at a predetermined position of the reel drive mechanism holder γ2 for driving the tape reel of the small tape cassette 63. After inserting the upper half 51 and lower half 57, the pull-out pins 60 and 62 are positioned on the back side of the mouse magnetic tape 64 of the small tape cassette 63, as shown in FIG.

Adapter 5 when the upper half 51 and lower half 67 are combined
The external dimensions of the tape cassette are approximately equal to those of the large tape cassette.

Further, as shown in FIG. 5, when the small tape force set holder 72 faces the cassette insertion slot 18 shown by the dotted chain line, the rear wall 73 of the upper half 51 is attached to the small tape cassette holder 72 of the cassette insertion slot 18. Since the part not facing the small tape cassette holder 72 is substantially covered, there is no possibility of erroneous operation of inserting the small tape forceps or other objects into the space other than the small tape cassette holder 72.

Next, each operation will be explained with reference to the drawings.

The case where the large tape cassette 4 is installed in the device will be described. When the large tape cassette 74 is inserted into the cassette insertion slot 18 in FIG.
Rotate it to the position shown by the solid line. When the large tape cassette 74 is inserted into the cassette holder 23 shown by the solid line, a switch (not shown) is turned on and the cassette holder drive motor starts, causing the drive arm 31 to rotate counterclockwise in FIG. As the cassette holder 23 moves and reaches the position indicated by the dotted line, the cassette holder 23 is also guided by the grooves 43 and 44 and slides.
Move the cassette holder 23 to the position indicated by the dotted line in Figure 1.
The large chip cassette 74 held in the tape drive mechanism 19 is attached to the tape drive mechanism 19 as shown by the dotted line in FIG. When transporting the large tape cassette 4 from the position where it is attached to the tape drive mechanism 19 to the position where it can be attached to and detached from the cassette holder 23 as shown by the solid line, the blinder rotating means rotates the blinder 36 and the large tape cassette 74. To avoid collision, the blinder 36 is rotated and held at the position shown by the two-dot chain line in the middle of the conveyance path. The blinder 36 is biased by a spring in a direction to close the cassette insertion port 18. And always,
In FIG. 1, it is positioned in contact with a stopper (not shown) at the position indicated by the dashed-dotted line.

Next, the case where the small tape cassette 63 is installed in the apparatus will be described.

When you press the small tape cassette switch (not shown),
As shown in FIG. 2, a cassette holder drive motor (not shown) rotates so that the cassette holder 23 moves to an intermediate position.

By means of the blinder rotation means interlocked with the drive arm 32 shown in FIG. 4, the blinder 36 is moved from the position where the cassette insertion port 18 is in the closed state to the intermediate position of the cassette holder 23 shown in FIG. Cassette insertion slot 18 shown in
is opened and rotated and held in a position that does not hinder the transportation of the large tape cassette.

Thereafter, the motor (not shown) rotates, the pinion 46 rotates counterclockwise in FIG. From the first position shown in Figure 1,
The upper half 61 of the adapter 60 is shown in FIG. The small tape cassette holder 72 is raised to the second position facing the cassette insertion slot 18 . At this time, the blinder abutting portion 76 at the upper end of the elevator 48 abuts a part of the blinder 36 and holds the blinder 35 in the position shown in FIGS. 2 and 3.

Next, the pinion 54 also rotates counterclockwise, and the elevator 66 and the lower half 57 of the adapter 60 also rise to the position shown in FIG. 2 via the rack 66.

The height positional relationship between the upper half 51 and the lower half 57 shown in FIG. 1 is the same as that shown in FIG.
The height positional relationship is such that the magnetic tape e4 does not come into contact with the magnetic tape 62.

In addition, the small tape cassette holder 72 is in the state shown in FIG.
It was moved to the right side in FIG. 2 within the upper half 61 in order to receive it. Of course, as can be seen from FIG. 6, the cassette insertion opening 18 is substantially covered by the wall 73 on the cassette insertion opening side of the upper half 51, except for the small tape cassette holder 72, so that the small tape cassette 63 can be inserted therein. The location can be easily determined.

In the state shown in FIG. 2, when the small tape cassette 63 is inserted into the small tape cassette holder 72 through the cassette insertion slot 18, a switch (not shown) is turned on, and the small tape cassette holder drive mechanism (not shown) operates to reduce the size of the tape cassette. The tape cassette holder 72 moves to the left in FIG. 2 while holding the small tape cassette 63, and the planar positional relationship between the small tape cassette 63 and the lower half 57 becomes as shown in FIG. At this time, the magnetic tapes 64 pass through the drawers 60 and 62, but as described above, they are in a height relationship that does not abut each other. Thereafter, the pinion 64 further rotates counterclockwise in FIG. 2, and the upper half 61 and the lower half 67 are combined as shown in the third factor. At this time, the pull-out pins 60 and 62 are inserted into the back side of the mouse magnetic tape 64 of the small tape cassette 63. In addition, since the outer dimensions of the combined adapter 50 are approximately equal to the outer dimensions of the large-sized chip cassette 74, in this state, the cassette holder drive motor (not shown) is reversely rotated to move the drive arm 31 clockwise from FIG. When the adapter 60 is rotated, the adapter 60 is inserted into the cassette holder 23 as shown in FIG.

The position of the cassette holder 23 shown in FIG. 3 is close to the position of the cassette holder 23 shown in FIG. 1D. Therefore, the blinder 36 attempts to rotate to a position that closes the cassette insertion port 18, but since it is held in contact with the elevator 48, as shown in FIG.

Maintain the open state shown in Figure 3. Thereafter, when the drive arm 31 again rotates the cassette holder drive motor (not shown) counterclockwise in FIG. 3, the cassette holder 23 moves in exactly the same manner as when the large tape cassette 74 is mounted. This time, the cassette holder 23 holds the small tape cassette 6.
It holds adapter 5o with built-in adapter 3, and adapter 6
0 is attached to the tape drive mechanism 19. Therefore, the small tape cassette 63 is attached to the tape drive mechanism 19.

Of course, from the state shown in Fig. 3, the cassette holder 23 is
When moving to the left in the figure, use the pull-out pin 60 as described above.
．． 62 is indicated by the dashed line in FIG.

Since the magnetic tape running path on the front side of the adapter 50 before installation is almost the same as the tape running path of a large tape cassette, the same problem will occur even if the adapter 6o is installed in the tape drive mechanism 19. does not occur.

Note that the relationship between the tape reel in the small tape cassette 63 and the reel drive mechanism of the tape drive mechanism 19 is almost the same as in the conventional device, so details will be omitted.

Next, due to the state in which the adapter 50 is attached to the tape drive mechanism 19, the adapter 50 is attached to the elevator 4 constituting the adapter drive means.
8.56, when the blinder 35 is transported to the position shown in FIG.
Since it is held as shown in the figure, it will not collide with the adapter 50 being conveyed. FIG. 5 shows its front view.

As described above, the magnetic recording/reproducing apparatus of this embodiment can use both large tape cassettes and small tape cassettes. It also eliminates the complexity of the mechanism for opening and closing the blinder when two types of cassettes, a large tape cassette and a small tape cassette, are inserted through a single cassette insertion opening.

Although the present embodiment has been explained using a magnetic recording/reproducing device, the present invention can be similarly applied to a device that records/reproduces information on a tape by mechanical, electrical, or optical means. is clear.

Furthermore, in order to install the large tape cassette or adapter and the tape drive mechanism relative to each other, the standard tape cassette or adapter was moved, but it is obvious that the same effect can be obtained by moving the tape drive mechanism. be.

Furthermore, when the cassette insertion slot and the small tape cassette holder face each other, the part of the cassette insertion slot that does not face the small tape cassette holder is covered by the rear wall of the upper half; It is also obvious that the same effect can be obtained by using a wall provided in the cassette or a shutter means that partially covers the cassette insertion port.

Effects of the Invention As described above, the present invention includes a tape cassette insertion slot into which a tape cassette is inserted, a cassette holder that holds a large tape cassette inserted from the tape cassette insertion slot, and a rotatable structure immediately after the tape cassette insertion slot. A blinder supported and provided to open and close the tape cassette insertion slot, a blinder rotation means for rotating the blinder, a small tape cassette holder for holding the small tape cassette inserted from the tape cassette insertion slot, and a small tape cassette holder for holding the small tape cassette inserted from the tape cassette insertion slot; an adapter having a tape pull-out means for pulling out the tape so as to be approximately equal to the tape running path of the large tape cassette; and a mounting means for mounting either the large tape cassette or the adapter holding the small tape cassette to the tape drive mechanism. , a small tape cassette holder has tape power.

When facing the tape cassette insertion slot, there is a means for substantially covering the part of the tape cassette insertion slot that does not face the small tape cassette holder, and a first position that does not interfere with the mounting operation of the large tape cassette by the mounting means; an adapter moving means having a blinder abutting portion for reciprocating the adapter to a second position facing the small tape cassette holder and abutting the blinder at the second position to open the cassette insertion port; With this feature, large tape cassettes and small-layer tape cassettes can be installed in the device simply by inserting them into the cassette insertion slot, and a mechanism for opening and closing the blinder when large and small tape cassettes are inserted into one cassette insertion slot. This eliminates the complexity of Furthermore, when inserting a small tape cassette, the cassette insertion slot is covered with a size that allows the small tape cassette to be inserted, making it extremely easy to operate without making mistakes. It has outstanding reliability and appearance that is invisible to the eye.
