The drive arm 13 is slidably engaged with the groove 14 of the drive arm 13 supported by the drive arm 13 .

The drive arm 13 is configured to rotate around the shaft 12 by rotation of a cassette holder drive motor (not shown).

When the drive arm 13 rotates counterclockwise in FIG. 2, the cassette holder 7 is guided by the alo and 11, moves horizontally at first, and finally moves vertically, as shown by the dotted line in FIG. , and attach a standard tape cassette or a small tape cassette to the tape drive mechanism as described below. A pinion 16 is attached to a shaft 15 provided on the vertical support plate 5 (6), and when the pinion 16 rotates, an elevator 18 having a rack 17 meshing with the pinion 16 is raised and lowered. Elevator 18 as shown in Figure 6
The protrusion 19 on the upper part of the pinion 16 is engaged with the groove 22 provided on the side surface of the upper half 21 of the adapter 20.
The upper half 21 is raised and lowered by the rotation of the upper half 21.

Similarly, a pinion 24 is attached to a shaft 23 provided on the vertical support plate 5 (6), and a rack 2 that engages with the pinion 24
Since the lower half 27 of the adapter 20 is placed on the elevator 26 having the lower half 5, when the binion 24 rotates, the elevator 26 and the lower half 27 move up and down.

FIG. 5 shows the main structure of the lower half 27 of the adapter 20 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 moving from the state shown in the figure to the left in Figure 4, the gear 28
rotates clockwise, and when adapter 20 moves to the right in FIG. 4, gear 28 rotates counterclockwise. The internal structure of the adapter 20 is well known from the VH3 type VH3-C outlet adapter, so I will not go into details, but in FIG. 5, when the gear 28 rotates clockwise, the rotating arm 29 The magnetic tape 34 is pulled out from the small tape cassette 33 by the pull-out pin 30 on the top and the pull-out pin 32 on the rotary arm 31, and the tape loop 35 is similar to the tape loop of the standard tape cassette, as shown by the dashed line.
It is configured to form a. Further, when the gear 28 rotates counterclockwise, the rotating arm 29 and the rotating arm 31 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 36 The magnetic tape is configured to be stored in the small tape cassette 33 by driving the take-up reel 37 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 7) holder 42 for holding a small tape cassette 33 is arranged so as to be slidable in the left-right direction in FIG. The lower half 27 has the aforementioned rotating arms 29, 31. A tape pull-out mechanism including pull-out pins 30 and 32 and a reel drive mechanism for driving the tape reel of the small tape cassette 33 are provided.

Then, as shown in FIG. 6, the upper half 21 and the lower half 27
When the small tape cassette 33 is inserted into the predetermined position of the small tape cassette holder 42 with the two separated, and the upper half 21 and the lower half 27 are combined, the mouse magnetic tape of the small tape cassette 33 is inserted as shown in FIG. The pull-out pins 30 and 32 are located on the back side of 34.

Adapter 2 when upper half 21 and lower half 27 are combined
The external dimensions of the tape cassette 0 are approximately equal to those of a standard tape cassette.

In addition, as shown in FIG. 6, a small tape cassette holder 4
When 2 faces the cassette insertion slot 3 shown by the dashed line, the rear wall 50 of the upper half 21 substantially covers the portion of the cassette insertion slot 3 that does not face the small tape cassette holder 42. An erroneous operation such as inserting a small tape cassette or other object into a space other than the small tape cassette holder 42 will not occur.
3J and is visible through the cassette insertion slot 3. In other words, the display on rc-VH3J cannot be seen when the upper half 21 is lowered, but when the upper half 2
1 is raised to make it visible when the device is compatible with small tape cassettes.

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. 2, when the standard tape cassette 45 is inserted into the cassette insertion slot 3 as shown by the dashed line in the same manner as before, a switch (not shown) is turned on and the cassette holder drive motor is started, and the drive arm 13 As the cassette holder 7 rotates counterclockwise and reaches the position indicated by the dotted line in Figure 2, the cassette holder 7 also slides guided by the grooves 10 and 11, moves to the position indicated by the dotted line in Figure 2, and is therefore held in the cassette holder 7. The standard tape cassette 45 is mounted on the tape drive mechanism 4 as shown by the dotted line in FIG. 2 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. 3, 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. 3, and the elevator 18 and the upper half 21 of the adapter 20 also rise via the rack 17 to the position shown in FIG. 3. 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. 3 via the rack 25. The height positional relationship between the upper half 21 and the lower half 27 shown in FIG.
．． The height position relationship is such that the magnetic tape 34 does not come into contact with the magnetic tape 32. Further, in the state shown in FIG. 3, the small tape cassette holder 42 is moved to the right in FIG. 3 within the upper half 21 in order to receive the small tape cassette 33 from the cassette insertion slot 3. Of course, as can be seen from FIG. 6, the cassette insertion opening 3 is almost covered by the rear wall 50 of the upper half 21 except for the small tape cassette holder 42, so the insertion position of the small tape cassette 33 is easy. can be determined. And when the upper half 21 rises, 'C-VH3J
The operator can safely insert the small tape cassette into the device.

When the small tape cassette 33 is inserted into the small tape cassette holder 42 through the cassette insertion slot 3 in the state shown in FIG. The tape cassette holder 42 moves to the left in FIG. 3 while holding the small tape cassette 33, and the planar positional relationship between the small tape cassette 33 and the lower half 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, they are in a height relationship where they do not come into contact with each other.

Thereafter, the pinion 24 further rotates counterclockwise in FIG. 3, and the upper half 21 and lower half 27 are combined as shown in FIG. 4. At this time, the extraction pins 30 and 32 are inserted into the back side of the mouse magnetic tape 34 of the small tape cassette 33. Further, 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 reversely rotated to rotate the drive arm 13 as shown in FIG. When rotated in the direction, the fourth
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. 4,
The cassette holder 7 moves in exactly the same way as when the standard tape cassette 45 is mounted. This time, the cassette holder 7 holds an adapter 20 containing a small tape cassette 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. 4 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 problem will occur even if the adapter 20 is attached to the tape drive mechanism 4. The relationship between the tape reel in the tape cassette 33 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.

As described above, the magnetic recording/reproducing apparatus according to 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. Furthermore, when the cassette insertion slot and the small tape cassette holder face each other, the 'CVH3J' display is visible inside the cassette insertion slot, but it is obvious that the same effect can be achieved by color coding, for example. be.

Furthermore, it is obvious that the display section does not need to be located inside the cassette insertion slot.

Effects of the Invention As described above, the present invention includes a tape cassette insertion port for inserting a tape cassette, a cassette holder for holding a large tape cassette inserted from the tape cassette insertion port, and a cassette holder for holding a large tape cassette inserted from the tape cassette insertion port. a small tape cassette holder for holding a small tape cassette; an adapter having tape pulling means for drawing out the tape in the small tape cassette so as to be substantially equal to the tape running path of the large tape cassette; and the large tape cassette or the small tape. A mounting means for mounting one of the adapters holding a cassette on the tape drive mechanism, and a display means for displaying which of the large tape cassette holder and the small tape cassette holder faces the tape cassette insertion slot. With this feature, standard tape cassettes and small tape cassettes can be installed in the device simply by inserting them into the cassette insertion slot.

Furthermore, when the installation becomes compatible with small tape cassettes, the display section allows the user to know at a glance, so the operator does not feel intimidated and the operability is significantly improved.
