Means for Solving the Problems F In order to solve the problems, the tape drive device of the present invention includes:
A tape cassette insertion slot for inserting a tape cassette. a cassette holder for holding a large tape cassette inserted from the tape cassette insertion slot; a blinder rotatably supported and provided immediately after the 0M tape cassette insertion slot for opening and closing the tape cassette insertion slot; and a blinder for opening and closing the tape cassette insertion slot; an adapter having a small tape cassette holder for holding a small tape cassette inserted from a cassette insertion slot; and a tape pull-out means for drawing out the tape in the small tape cassette so as to be approximately equal to the tape running path of the large tape cassette; The adapter holds a tape cassette or a small tape cassette. a mounting means for mounting on the tape drive mechanism; 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 an adapter moving means for reciprocating the large tape cassette, and when the large tape cassette is mounted on the tape drive mechanism by the mounting operation, the adapter moving means is driven to move a part of the blinder from the first position. It is provided with means for moving it to a predetermined intermediate position to prevent it from being released.

Effect Due to the above configuration, when attaching a large tape cassette to the device as in the past, it is not necessary to remove the adapter inserted into the device and store it outside the device, or to use a small tape cassette. When using a large tape cassette, you can simply insert the large tape cassette into the cassette insertion slot without having to insert an adapter stored outside the device into the device. If a small tape cassette is used, it can be easily installed in the device by inserting the small tape cassette into an adapter inside the device. Furthermore, when a large tape cassette is installed, the cassette insertion slot is locked in the closed state by a blinder.
Even if a small tape cassette or a large tape cassette is further inserted into the cassette insertion slot due to malfunction, it can be prevented from being inserted.

After all, the upper half 27 is raised and lowered by the rotation of the pinion 22.

Similarly, a pinion 30 is attached to a shaft 29 provided on the vertical support plate 5, and a lower half 33 of the adapter 26 is placed on an elevator 32 having a rack 3l that engages with the pinion 30, so that the pinion 30 rotates. Then, the structure is such that the elevator 32 and the lower half 33 move up and down.

The vertical support plate 6 is also provided with the same configuration as described above. Here, the elevator 24.32 constitutes an adapter moving means.

FIG. 7 shows the main structure of the lower half 33 of the adapter 26 built into the device. The gear 34 rotatably supported by the lower gear 733 is engaged with a rack portion (not shown) of the vertical support plate 5 shown in FIG.
When moving from the state shown in the figure to the left in Fig. 5, the gear 34
rotates clockwise, and when adapter 26 moves to the right in FIG. 5, gear 34 rotates counterclockwise. The internal structure of the adapter 26 is well known from VHS system VHS-C cassette adapters, etc.
Although I will not go into details, in FIG. 7, when the gear 34 rotates clockwise, the pull-out pin 36 on the rotating arm 35 and the pull-out pin 38 on the hill of the rotating arm 37 are shown.
, the magnetic tape 40 is transferred from the small tape cassette 39.
is pulled out to form a table loop 4l similar to the table loop of the large table cassette l, as shown by the two-dot chain line. Further, when the gear 34 rotates counterclockwise, the rotating arm 35 and the rotating arm 37
moves from the state shown by the two-dot chain line to the state shown by the solid line, shrinks the table loop, and drives the take-up reel 43 in the small tape cassette 39 by the gear 42, so that the magnetic tape 40 is moved into the small tape cassette 39. It is designed to store.

The adapter 26 has a structure that can be divided into an L half 27 and a lower half 733 as shown in FIG.
Boss 44.45 planted at 7 and t planted at lower 8th floor 33
The structure is such that the relative positions in the horizontal direction do not shift due to the shafts 46 and 47. The E-har 727 has a fourth small tape cassette holder 48 that holds a small tape cassette 39.
It is arranged to be able to slide freely in the left and right directions in the figure. lower half 33
The above-mentioned rotating arm 35.37% pull-out pin 36.
Tape drawer mechanism including 38 and small tape cassette 3
A reel drive mechanism for driving the table reels of 9 is provided. And as shown in Figure 6, L-har 727
When the small tape cassette 39 is inserted into the predetermined position of the small tape cassette holder 48 with the upper half 27 and the lower half 733 separated, and the upper half 27 and the lower half 733 are combined, the seventh
As shown in the figure, pull-out pins 36 and 38 are positioned on the back side of the mouse magnetic tape 40 of the small tape cassette 39. The outer dimensions of the adapter 26 when the upper half 727 and the lower half 33 are combined are approximately equal to the outer dimensions of the large tape cassette.

In addition, as shown in FIG. 6, a small tape cassette holder 48
When facing the cassette insertion slot 3 shown by the dashed line, the rear wall portion 49 of the half 27 on the cassette insertion slot side substantially covers the portion of the cassette insertion slot 3 that does not face the small tape cassette holder 48. Therefore, an erroneous operation such as inserting a small tape cassette or other object into a space other than the small tape cassette holder 48 does not occur.

Next, each operation will be explained with reference to the drawings. The case where the large tape cassette 20 is installed in the apparatus will be described. When the large tape cassette 20 is inserted into the cassette insertion slot 3 in FIG. 1, the front L end 6'r of the cassette, indicated by the dashed line, comes into contact with the blinder l5, and the blinder l5 is rotated to the position indicated by the solid line. Large tape cassette 2
0 is inserted into the cassette holder 7 indicated by the solid line to the mounting position, a switch (not shown) is turned on, the cassette holder drive motor starts, and the drive arm 13a is moved counterclockwise in FIG. 1 via the rod 16. As it rotates and reaches the position indicated by the two-dot chain line, the cassette holder 7 also has grooves 1ga and lia.
The large tape cassette 20 is guided by the tape drive mechanism 4 and slides to the position indicated by the two-dot chain line in FIG. 1, and is held by the cassette holder 7. It is installed like a conventional device. At this time, the blinder 15 is released from the hold by the blind opener 19 by the cam gear 17a, and at the same time is biased by a spring (not shown) in the direction of closing the cassette insertion slot 3, so that It is positioned in contact with a stopper (not shown) at the position indicated by the dashed line, and the cassette insertion port 3 is closed. Then, almost simultaneously with the installation of the large tape cassette 20, the cassette installation detection switch (not shown) is activated, the adapter lifting motor (not shown) is rotated, and the pinion 16 is rotated counterclockwise at the 11th point. Rotating, the elevator 24 and the hill half 27 of the adapter 26 are also raised via the rack 23 from the first position to the intermediate position in FIG. When the blinder 15 rotates, the height L rises up to the height where the tip of the blinder 15a comes into contact with the tip side surface 24a of the elevator 24 and the rotation is blocked. In the state shown in FIG. 2, even if another small tape cassette 39 or large tape cassette 20 is mistakenly inserted into the cassette insertion slot 3, the blinder 15 will come into contact with the end side surface 24a of the elevator 24 and will not be able to rotate. , insertion is prevented.

Next, the large tape cassette 20 is attached and detached from the position where it is attached to the tape drive mechanism 4 to the cassette holder 7 shown by the solid line.
・When transporting the machine to a position where it can be moved. The blinder rotating means shown in FIG. 3 includes a blinder 15 and a large tape cassette 20.
The blinder 15 is rotated and held at the position shown by the two-dot chain line in FIG.

Next, the case where the small tape cassette 39 is installed in the apparatus will be described. When the small tape cassette switch (not shown) is pressed, the cassette holder drive motor (not shown) rotates so that the cassette holder 7 moves to a position intermediate between the guide grooves 10a and llb, as shown in FIG. At this time, the blinder 15 is moved from the position where the cassette insertion opening 3 is closed to the intermediate position of the cassette holder 7 as shown in FIG. Cassette insertion slot 3 as shown in Figure 4.
Open the tape cassette and rotate it in a position that does not interfere with the transportation of the large tape cassette.

After that, the adapter lifting motor (not shown) rotates,
Binion 22 rotates counterclockwise in FIG.
3, the elevator 24 moves the L half 27 of the adapter 26 toward the cassette insertion slot 3 shown in FIG. 4 from the first position shown in FIG. Increase by 1 to the second position. At this time, the blinder contact surface 24b at the upper end of the elevator 24 contacts a part of the blinder 15. The blinder 15 is held in the position shown in FIGS. 4 and 5.

Next, the binion 30 also rotates counterclockwise, and the elevator 32 and the lower harness 73 of the adapter 26 are connected to each other via the rack 31.
3 also rises to the second position shown in FIG. The height positional relationship between the upper har 727 and the lower har 733 shown in FIG. 4 is the same as that shown in FIG.
The height position relationship is such that the magnetic tape 40 does not come into contact with the magnetic tape 38.

Further, in the state shown in FIG. 4, the small tape cassette holder 48 has been moved to the right side in FIG. 4 within the top half 27 in order to receive the small tape cassette 39 from the cassette insertion opening 3. Of course, as can be seen from FIG.
9 covers all parts other than the small tape cassette holder 48, so the insertion position of the small tape cassette 39 can be easily determined.

In the state shown in FIG. 4, when the small tape cassette 39 is inserted into the small tape cassette holder 48 through the cassette insertion slot 3, a switch (not shown) is turned on and the small tape cassette holder is activated! The lJa mechanism (not shown) operates, and the small tape cassette holder 48 moves to the left in FIG. 4 while holding the small tape cassette 39.
The planar positional relationship between the lower bar 733 and the lower bar 733 is as shown in FIG. At this time, the magnetic tapes 40 pass through the pull-out pins 36 and 38, but as described above, they are set in a height relationship such that they do not come into contact with each other. Thereafter, the binion 30 is further rotated counterclockwise in FIG. 4, and the old half 727 is combined with the lower half 33 as shown in FIG. At this time, the drawer bin 36.38
is inserted into the back of the mouse magnetic tape 40 of the small tape cassette 39. In addition, since the outer dimensions of the combined adapter 26 are approximately equal to the outer dimensions of the large table cassette 20, in this state, the cassette holder drive motor (not shown) is reversed and the drive arm 13a is rotated clockwise from FIG. 5, the adapter 26 is inserted into the cassette holder 7 as shown in FIG.

The position of the cassette holder 7 shown in FIG. It is close to the position of the cassette holder 7 shown in FIG. Therefore, the blinder 15 tries to rotate to the position where the cassette insertion port 3 is closed, but the blinder contact surface 24b of the elevator 24
The open state shown in FIGS. 4 and 5 is maintained by the t-clam held in contact with the Thereafter, when the cassette holder drive motor (not shown) again rotates the drive arm 13a counterclockwise in FIG. 5, the cassette holder 7 moves in exactly the same way as when the large tape cassette 20 is attached. .

This time, the cassette holder 7 holds an adapter 26 containing a small tape cassette 39, and the adapter 26 is attached to the tape drive mechanism 4. Therefore, the small tape cassette 39 is attached to the tape drive mechanism 4. Of course, when the cassette holder 7 moves to the left in FIG. 5 from the state shown in FIG. 5, the pull-out pin 36. 3
8 moves to the position shown by the two-dot chain line in FIG. No problem will occur even if 26 is attached to the side 4 of the tape drive machine. Note that the relationship between the table reel in the small tape cassette 39 and the reel drive mechanism of the tape drive mechanism 4 is almost the same as that of the conventional device, so the details will be omitted.

Next, from the state where the adapter 26 is attached to the tape drive mechanism 4, the adapter 26 is attached to the elevator 24. which constitutes the adapter drive means.
32, when the blinder l5 is transported to the position shown in FIG.
Since it is held on the blinder abutting surface 24b as shown in the figure, it will not collide with the adapter 26 being conveyed.

As mentioned above, the magnetic recording and reproducing device 1 of this embodiment can use both large tape cassettes and small tape cassettes, and can also use two types of tape cassettes, large and small, from one cassette insertion slot. This also eliminates the complexity of the blinking opening/closing mechanism and blinking lock mechanism when inserting a cassette.

In addition. Although the embodiment described in section h has been explained using a magnetic recording and reproducing device, the present invention can be similarly applied to a device that records and reproduces information on a tape by other means such as mechanically, electrically, or optically. is obvious.

Also, in order to install the large tape cassette or adapter and the tape drive mechanism relative to each other, the large 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; however, this is not limiting; It is also obvious that the same effect can be obtained by using a provided wall or a shutter means that partially covers the cassette insertion port.

According to the present invention, a large tape force set and a small tape cassette can be installed in the apparatus simply by inserting them into the cassette insertion slot. In addition, if children malfunction and try to insert a small tape cassette or a large tape cassette when a large tape cassette is installed,
Because a part of the adapter moving means is located behind the blinder and prevents its release, even if you push the blinder with the edge of the cassette to change the cassette insertion slot from the closed state to the open state, rotation is blocked and the cassette cannot be inserted.
