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

FIG. 6 is a perspective view showing the appearance of an embodiment of the cassette loading device of the present invention. This cassette mounting device 1 has a tape cassette insertion slot 3 on a front panel 2. 1 to 4 are incorporated into the device 1. FIG. FIG. 3 is a sectional side view of a main part of a standard tape cassette mounting mechanism and a small tape cassette mounting mechanism. In FIGS. 1 to 4, a cassette holder 7 is movably provided between vertical support plates 6.6 disposed substantially perpendicularly to the left and right sides of the tape drive mechanism 4 of the apparatus. Projections 8 and 9 of the cassette holder 7 are slidably engaged in guide grooves 1° and 11 provided in the vertical support plate 5.6;
．． The drive arm 13 is slidably engaged with a groove 14 of a drive arm 13 rotatably supported by a shaft 12 erected on the shaft 6 .

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 groove 10.11 and moves first horizontally and finally vertically to the tape drive mechanism 4 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. Axis 16 on vertical support plate 6.6
A pinion 16 is attached to the holder, and when the pinion 16 rotates, an elevator 18 having a rack 17 meshing with the pinion 16 moves up and down.

As shown in FIG. 7, the protrusion 19 on the upper part of the elevator 18 engages with the groove 22 provided on the side surface of the upper half 21 of the adapter 20, so that the upper half 21 eventually rotates by 160 rotations.
It looks like it's going up and down.

Further, as shown in FIG. 7, at the rear of the elevator 18, when the small tape cassette holder 42 rises to a position facing the cassette H11 population 3, a portion of the cassette insertion slot 3 that does not face the small tape cassette holder 42 is inserted. It is integrally constructed with a wall portion 5o that almost covers it.

Similarly, a pinion 2 is attached to the shaft 23 provided on the vertical indicator plate 5.6.
4 is attached to the rack 25 that meshes with the pinion 24.
The elevator 26 has a lower half 2 of the adapter 2o.
7 is mounted, so that when the pinion 24 rotates, the elevator 26 and the lower half 27 move up and down.

FIG. 6 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 meshes 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 28F
When the adapter 20 rotates clockwise once and moves to the right in FIG. 4, the gear 28 rotates counterclockwise. The internal structure of the adapter 2o is well known from the VH5 type V HS-C cassette adapter, so I will not go into details, but in FIG.
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 29 and the rotating arm 3
1 moves from the state shown by the one-dot chain line to the state shown by the solid line and the broken line, and the tape loop is shortened, and the gear 36
The winding series 37 in the small tape cassette 33 is
The magnetic tape is driven to store the magnetic tape in the small tape cassette 33.

The adapter 2o 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 a tape pull-out mechanism including the aforementioned rotating arms 29, 31 and pull-out pins 30, 32, and a reel drive mechanism for driving the tape reel of the small tape cassette 33.

Then, as shown in FIG. 7, the upper bar 221 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 . The pull-out pins 30 and 32 are positioned on the back side of the tape 34.

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

In addition, as shown in FIG. 7, a small tape cassette holder 42
When the elevator 18 faces the cassette insertion slot 3 shown by the dashed line, the rear wall 5° of the elevator 18 substantially covers the portion of the cassette insertion slot 3 that does not face the small tape cassette holder 42, making it compact. An erroneous operation such as inserting a small tape cassette or other object into a space other than the tape cassette holder 42 does not occur.

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 46 is inserted into the cassette insertion slot 3 in FIG. 1, it is inserted into the cassette holder 7 after coming into contact with the guide member 212L.

Next, after inserting the standard type tape cassette 46 shown in FIG. 2 as shown by the dashed line in the same manner as before, when the standard type tape cassette 45 is pressed, a switch (not shown) is turned on and the cassette holder drive motor is activated. starts, and the drive arm 13 rotates counterclockwise and reaches the position indicated by the dotted line in Fig. 2.The cassette holder also slides guided by the grooves 10 and 11 and reaches the position indicated by the dotted line in Fig. 2. move and therefore the cassette holder 7
The standard cassette tape 46 held in the cassette tape 46 is loaded into the tape drive mechanism 4 as shown by the dashed line in FIG.

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 nof 21 of the adapter 20 also reach the position shown in FIG. Rise. 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. 3 via the rack 25. The height positional relationship between the upper half 21 and the lower half 27 shown in FIG. 3 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. 3, the small tape cassette holder 42 is moved to the right side in FIG. 3 within the upper nozzle 21 in order to receive the small tape cassette 33 from the cassette insertion slot 3. As can be seen from FIG. 7, the cassette insertion slot 3 is substantially covered by the rear wall 6o of the elevator 18 except for the small tape cassette holder 42, so the insertion position of the small tape cassette 33 can be easily determined. .

In the state shown in Fig. 3, 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. 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.
As shown in FIG. 4, the upper half 21 and the lower half 27 are combined. 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.

In addition, since the external dimensions of the combined adapter 2o are approximately equal to the external dimensions of the standard tape cassette 45, in this state, the cassette holder drive motor (not shown) is reversely rotated 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 the adapter 2o containing the 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. 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 the same problem does not occur even when the adapter 2o 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.

Although the above embodiment is explained using a cassette loading device, the present invention is equally applicable to a device that records and reproduces information on a tape mechanically, electrically, or optically. 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 to hold a tape cassette, 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 an adapter that holds a large tape cassette or a small tape cassette. a mounting means for mounting one end of the adapter onto the tape drive mechanism, and reciprocating the adapter 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. a covering means for covering a portion of the tape cassette insertion slot not facing the small tape cassette holder in the second position; and a guide member disposed on the top surface of the adapter for guiding the large tape cassette to the cassette holder. When the large tape cassette is attached to the tape drive mechanism, by moving the adapter from the first position to the second position, the large tape cassette and the small tape cassette can be inserted into the cassette insertion slot. You can attach it to the device by simply doing this. Furthermore, when inserting a large tape cassette into the cassette holder, the large tape cassette is guided by the guide member, so it can be easily inserted, and the operability can be greatly improved.
