FIG. 6 shows the main structure of the lower half 2a of the adapter 2° built into the device. The 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 20 moves to the left in FIG. 6 from the state shown in the figure, the gear 28 rotates clockwise, and when the adapter 20 moves to the right in FIG. 5, the gear 28 rotates counterclockwise. . The internal structure of adapter 2o is VH3 type V
Since it is well known as an adapter for H8-C cassette, etc., I will not go into details, but in Fig. 6, gear 2
8 rotates clockwise, the magnetic tape 34 is removed from the 4\ type tape cassette 33 by the drawer bin 30 on the rotating arm 29 and the drawer bin 32 on the rotating arm 31.
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 29 and the rotating arm 31 move from the state shown by the dashed-dotted line to the state shown by the solid line and the broken line, and the tape loop is shortened and the gear 36 The configuration is such that a take-up reel 37 inside the small tape cassette 33 is driven to store the magnetic tape inside the 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.
0.41, the structure is such that the relative position in the horizontal direction does not shift. 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 half 27 is provided with the aforementioned rotating arm 29.3j, a tape pull-out mechanism including the pull-out bin 30.32, and a reel drive mechanism for driving the tape reel of the small tape cassette 33. Then, as shown in FIG. 6, with the upper half 21 and the lower half 27 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 27 are separated. When assembled, the pull-out pins 30 and 32 are positioned on the back side of the mouse magnetic tape 34 of the small tape cassette 33, as shown in FIG.

Adapter 2 when upper half 21 and lower half 27 are combined
The external dimensions of o are approximately equal to those of a standard tape cassette.

In addition, as shown in FIG. 7, a small tape cassette holder 42
When the cassette insertion port 3 is opposed to the cassette insertion port 3 shown by the dashed line, the rear wall portion 60 of the upper half 21 substantially covers the portion of the cassette insertion port 3 that is not opposed to the small tape cassette holder 42.

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

The case where the standard tape cassette 46 is installed in the apparatus will be described. When the standard tape cassette 45 is inserted into the cassette insertion slot 3 as shown in FIG. As it rotates counterclockwise and reaches the position indicated by the dotted line, the cassette holder 7 also moves into groove 1.
The standard tape cassette 46, which is guided by the tape drive mechanism 4 and moved to the position indicated by the dotted line in FIG. It is installed in the same way as a conventional device.

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. 3, a cassette holder drive motor (not shown) rotates so that the cassette holder 7 moves to an intermediate position. When the detection switch 62 detects that the cassette holder 7 has moved to the intermediate position, the cassette holder drive motor (not shown) is stopped.

Thereafter, the motor (not shown) rotates, the pinion 16 rotates counterclockwise in FIG. 3, and the elevator 18 and the upper half 21 of the adapter 2o also rise via the rack 17 to the position shown in FIG. 4. At the same time, the pinion 24 also rotates counterclockwise, and the elevator 26 and the lower half 27 of the adapter 2o also rise to the position shown in FIG. 4 via the rack 26.

The height positional relationship between the upper...-721 and the lower...-727 shown in Fig. 4 is as shown in Fig. 7.
Even if the small tape cassette 33 is inserted into the bin 30.3
The height positional relationship is such that the magnetic tape 34 does not come into contact with the magnetic tape 2.

Further, in the state shown in FIG. 4, the small tape cassette holder 42 is moved to the right in FIG. 4 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 7, the cassette insertion slot 3
Since the rear wall 60 of the upper half 21 substantially covers the parts other than the small tape horn set holder 42, the insertion position of the small tape cassette 33 can be easily determined.

In the state shown in Fig. 4, 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) operates to reduce While holding the small tape cassette 33, the tape cassette holder 42 moves to the left in FIG.
- The plane positional relationship with F2 ends as shown in FIG. At this time, the magnetic tape 34 passes through the pull-out pins 30 and 32, but as described above, they are in a height relationship where they do not come into contact with each other.

Thereafter, the pinion 24 is further rotated counterclockwise in FIG. 4, and the upper half 21 and the lower half 21 are combined with each other as shown in FIG. 6. At this time, the drawer bin 30, 32 is inserted into the back side of the mouse magnetic tape 34 of the small tape cassette 33. The outer dimensions of the combined adapter 20 are still approximately equal to those of the standard tape cassette 46, so in this state, the cassette holder drive motor (not shown) is reversed and the drive arm 13 is rotated clockwise in FIG. When rotated to the 6th
As shown in the figure, the adapter 20 is inserted into the cassette holder 7.

After that, the cassette holder drive motor (not shown) is turned on again.
When the drive arm 13 rotates counterclockwise in FIG. 5, the cassette holder 7 moves in exactly the same manner as when the standard tape cassette 46 is mounted. Now cassette holder 7
holds an adapter 20 containing a small tape force set 33, and the adapter 20 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. 5 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 no similar problem occurs 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 according to one embodiment of the present invention can use both standard tape cassettes and small tape cassettes.

Although the above embodiments have been explained using a magnetic recording and reproducing device, the present invention is equally applicable to devices that record and reproduce information on a tape mechanically, electrically, or optically by means of the same ground. It is obvious that it can be done.

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 has 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 small tape cassette inserted from the tape cassette insertion slot. An adapter that has a small tape cassette holder that holds a tape cassette, a tape pull-out means that pulls 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 an adapter that holds a large tape cassette or a small tape cassette. The adapter is reciprocated between a first position where the small tape cassette holder faces the tape cassette insertion slot and a second position which does not interfere with the mounting operation of the large tape cassette by the mounting means. By including the adapter moving means for moving the adapter and the detecting means for detecting that the cassette holder is in a position that does not prevent the adapter moving means from reciprocating the adapter between the first position and the second position,
Standard tape cassettes and small tape cassettes can be installed in the device simply by inserting them into the cassette insertion slot. In addition, when changing the state of the device from a standard cassette usage state to a small cassette usage state, the operation timings of the cassette mounting means and the adapter movement means, which are driven by separate motors, can be accurately separated. It is possible to provide a highly reliable cassette mounting device that is free from damage to the device due to contact with the adapter moving means.
