FIG. 2 shows the main structure of the lower half 27 of the adapter 2° built into the device. A gear 28 rotatably supported by the lower half 27 is engaged with a rack portion (not shown) of the vertical support plate 6 shown in FIG.
When the adapter 2o moves to the left in FIG. 4 from the state shown in the figure, the gear 28 rotates clockwise, and when the adapter 2o moves to the right in FIG. 4, the gear 28 rotates counterclockwise. . Since the internal structure of the adapter 2o is well known, we will not go into details, but in Fig. 2,
When the gear 28 rotates clockwise, the pull-out pin 3o on the rotating arm 29 and the pull-out pin 3 on the rotating arm 31
2, the magnetic tape 3 is removed from the small tape cassette 33.
4 is pulled out to form a tape loop 36 similar to the tape loop of a standard tape cassette, as shown by the dashed line. Further, when the gear 28 rotates counterclockwise, the rotating arm 2e and the rotating arm 31
The tape loop is moved from the state shown by the dashed line to the state shown by the solid line and the broken line, and at the same time, the gear 36 moves the take-up reel /l/3 in the small tape cassette 33.
7 is driven to store a magnetic tape in a small tape cassette 33.

The adapter 20 has a structure that can be divided into an upper half 21 and a lower half 27 as shown in FIG.

In the upper half 21, a small tape cassette holder 42 holding a small tape cassette 33 is arranged so as to be slidable in the left-right direction in FIG. The lower nozzle 27 is provided with a tape pull-out mechanism including the aforementioned rotating arms 29, 31 and pull-out pins 30.degree. 32, and a reel drive mechanism for driving the tape reel of the small tape cassette 33. Then, as shown in FIG. 3, with the upper half 21 and the lower half 727 separated, the small tape cassette 33 is inserted into the predetermined position of the small tape cassette holder 42, and then the upper half 21 and the lower half 727 are inserted.
1 and the lower nozzle 27 are combined, the pull-out pins 30 and 32 are located on the back side of the mouse magnetic tape 34 of the small tape cassette 33, as shown in FIG.

When combining the upper half 21 and the lower half 27, the pins 21 & planted on the side of the upper half 21 are connected to the lower half 27.
It enters the guide groove formed on the side of the
The protrusion 21b provided on the side surface of the adapter 21 comes into contact with the inner side surface of the lower half 27 while sliding thereon. It's Nishide.

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

The case where the standard tape cassette 45 is installed in the apparatus will be described. In FIG. 6, when the standard tape cassette 46 is inserted into the cassette insertion slot 3 as shown by the dashed line in the same manner as in the past, a switch (not shown) is turned on and the cassette holder drive motor starts, and the drive arm 13 As the cassette holder 7 rotates counterclockwise and reaches the position indicated by the dotted line in Fig. 6, the cassette holder 7 also slides guided by the grooves 10 and 11, moves to the position indicated by the dotted line in Fig. 5, and is therefore held in the cassette holder 7. The standard tape cassette 46 is mounted on the tape drive mechanism 4 as shown by the dotted line in FIG. 6 in the same manner as in the conventional apparatus.

Next, the case where the small tape cassette 33 is installed in the apparatus will be described.

When you press the small tape cassette switch (not shown),
As shown in FIG. 6, a cassette holder drive motor (not shown) rotates so that the cassette holder 7 moves to an intermediate position.

Thereafter, the motor (not shown) rotates, the pinion 16 rotates counterclockwise in FIG. 6, and the elevator 18 and the upper half 21 of the adapter 20 also rise to the position shown in FIG. 6 via the rack 17. At the same time, the pinion 24 also rotates counterclockwise, and the elevator 26 and the lower half 27 of the adapter 20 also rise to the position shown in FIG. 6 via the rack 25.

The height positional relationship between the upper half 721 and the lower half 27 shown in FIG. 6 is as shown in FIG.
Even if the small tape cassette 33 is inserted into the pin 30°32
The height positional relationship is such that the magnetic tape 34 does not come into contact with the magnetic tape 34.

Further, in the state shown in FIG. 6, the small tape cassette holder 42 is moved to the right in FIG. 6 within the upper half 21 in order to receive the small tape cassette 33 from the cassette insertion slot 3. Of course, as you can see from Figure 3, the cassette insertion slot 3
Since the rear wall 60 of the upper half 21 substantially covers the parts other than the small tape cassette holder 42, the insertion position of the small tape cassette 33 can be easily determined.

In the state shown in FIG. 6, when the small tape cassette 33 is inserted into the small tape cassette holder 42 through the cassette insertion slot 3, a switch (not shown) is turned on and the small tape cassette holder drive mechanism (not shown) is activated. The small tape cassette holder 42 moves to the left in FIG. 6 while holding the small tape cassette 33, and the planar positional relationship between the small tape cassette 33 and the lower flap 27 becomes as shown in FIG. At this time, the magnetic tape 34 passes through the pull-out pins 30 and 32, but as described above, the magnetic tapes 34 are in a height relationship such that they do not come into contact with each other. Thereafter, the pinion 24 further rotates counterclockwise in FIG. 6, and as shown in FIG.
move in the direction of merging.

At this time, as shown in Figure 1 (8) to p, the top...-72
The pins 21a provided on the side wall of the upper half 21 enter into the guide grooves 28 provided on the lower half 21, and the protrusions 21b provided on the side wall of the upper half 21 enter the inner side wall surface of the lower half 21. Combine while sliding.

Further, when the pin 21a enters the guide groove 28, there is a tapered portion 28a in the opening, and the pin 21a smoothly enters the parallel portion 28b and is guided. Further, since a part of the taper ends before the pull-out pin 30° 32 and the magnetic tape 34 overlap in the height direction, a small tape cassette holder 42 holding a small tape cassette 33 is provided by this parallel portion 28b. The longitudinal position of the upper half 21 and the lower half 27 having the cassette positioning pin 52 is regulated, and the drawer pin 30
．． 32 can be reliably inserted into the back of the mouse magnetic tape 34 of the small tape cassette 33.

Furthermore, just before the assembly is completed, the cassette positioning pin 52 provided on the lower half 27 is inserted into the small tape cassette 33.
When engaging the positioning hole (not shown) of the pin 21a
is located in the wide part 2Bc of the guide groove 28, and is a small tape cassette holder 42 holding a small tape cassette 33.
The upper half 21 having the cassette positioning pin 62 and the lower half having the cassette positioning pin 62 have a predetermined width and a degree of freedom in the front-rear direction.
2 is a positioning hole for the small tape cassette 33 (not shown)
enters without resistance, resulting in smooth completion of merging.

Furthermore, since the outer dimensions of the combined adapter 20 are approximately equal to the outer dimensions of the standard tape cassette 45, in this state, the cassette holder drive motor (not shown) is reversed to move the drive arm 13 clockwise in FIG. When the adapter 2o is rotated, the adapter 2o is inserted into the cassette holder 7 as shown in FIG.

After that, the cassette holder drive motor (not shown) is turned on again.
When the drive arm 13 rotates counterclockwise in FIG. 4, the cassette holder 7 moves in exactly the same manner as when the standard tape cassette 46 is mounted. This time cassette holder 7
holds an adapter 2o containing a small tape cassette 33, and the adapter 2o is attached to the tape drive mechanism 4.

Therefore, the small tape cassette 33 is attached to the tape drive mechanism 4. Of course, when the cassette holder 7 moves from the state shown in FIG. 7 to the left in FIG. Therefore, the magnetic tape running path on the front side of the adapter 20 before attachment is approximately the same as the tape running path of a standard tape cassette, and the same problem does not occur even when the adapter 20 is attached to the tape drive mechanism 4.

Note that the relationship between the tape reel in the small tape cassette 33 and the reel drive mechanism of the tape drive mechanism 4 is almost the same as in the conventional device, so the details will be omitted.

As described above, the cassette mounting device of this embodiment can use both standard tape cassettes and small tape cassettes.

In this embodiment, the magnetic recording and reproducing apparatus uses a cassette and tape loading device. It is obvious that the present invention can be similarly applied even if

Furthermore, in order to install the standard 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. It is.

Effects of the Invention As described above, the present invention provides a cassette holder for holding a large tape cassette inserted from a tape cassette insertion slot;
A small tape cassette holding member having a small tape cassette holder that holds a small tape cassette inserted from a tape 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. and a tape drawer member having a small cassette positioning member, and a mounting means for mounting either one of the adapters holding a large tape cassette or a small tape cassette to a tape drive mechanism. By providing a protrusion on one side of the small tape cassette holding member and the tape pull-out member, and providing a guide groove on the other side in which the protrusion can slide, the large tape cassette and A small tape cassette can be attached to the device simply by inserting it into the cassette insertion slot, and when using a small tape cassette, a guide groove regulates the positional relationship between the small tape cassette holding member and the tape pull-out member, allowing the tape to be The pull-out means can be reliably inserted into the back side of the magnetic tape of the mouse of the small tape cassette to avoid tape damage and obtain high reliability of the device.

Furthermore, when the small tape cassette holding member and the tape pull-out member are combined, the guide groove includes a position where the protrusion reaches and the groove width in the vicinity thereof is thicker than the groove width in other parts. When the small tape cassette held in the upper half is regulated by the small cassette positioning member installed in the lower half, play occurs between the upper half and the lower half, and the small cassette is not placed in the specified position relative to the lower half. Since the small tape cassette can be moved within the range of It is possible to reliably unite the tape cassettes, and to obtain high reliability of the apparatus when using small tape cassettes.
