It is driven by the pinion 69 and guided by guide grooves 71a, 71b, and 71c, and moves through the small tape cassette storage/takeout position C shown in FIG. 12. At position C, the small tape cassette insertion position of the small tape cassette adapter 72 inserted into the adapter housing 66 faces the small tape cassette insertion opening 64 of the top plate 63, so the small tape cassette is inserted at this position 1c. Cassettes can be replaced.

Problems to be Solved by the Invention However, with the above configuration, when a standard tape cassette is installed in the device, the adapter inserted in the device must be removed from the device and stored outside the device. . Additionally, when using a small tape cassette, an adapter must be stored outside the device and inserted into the device.

In view of the above-mentioned problems, the present invention provides a cassette loading device which has a built-in small tape cassette adapter for loading a small tape cassette into the device, thereby improving operability.

Means for Solving the Problems In order to solve the above problems, the cassette loading device of the present invention includes a tape cassette insertion port into which a tape cassette is inserted;
A cassette holder 5 holds a large tape cassette inserted from the tape cassette insertion slot, a small tape cassette holder holds a small tape cassette inserted from the tape cassette insertion slot, and a large tape cassette holds the tape in the small tape cassette. an adapter having a tape pull-out means for pulling out the tape so as to be drawn out so as to be substantially equal to the tape running path; a mounting means for mounting either one of the adapter holding a large tape force center or a small tape cassette to a tape drive mechanism; an adapter moving means for reciprocating the adapter between a first position that 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; It is constructed with retaining means that can be selectively engaged.

Effects of the present invention With the above-described configuration, when a standard tape cassette is installed in a device as in the past, the adapter inserted into the device can be removed from the device and stored outside the device, or a small tape cassette can be attached to the device. When using a standard tape cassette, insert the standard tape cassette into the cassette insertion slot without having to insert the adapter stored outside the device into the device. If a small tape cassette is used, it can be easily installed in the device by simply inserting the small tape cassette into the adapter inside the device.

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

FIG. 4 is a perspective view showing the appearance of an embodiment of a magnetic recording/reproducing apparatus using the cassette loading device of the present invention. This magnetic recording and reproducing apparatus 1 has a tape cassette insertion slot 3 on a front panel 2. 1 to 3 are side views of essential parts showing a standard tape cassette mounting mechanism and a small tape cassette mounting mechanism incorporated in the apparatus 1. FIG. In FIGS. 1 to 3, a cassette holder 7 is movably provided between vertical support plates 5.6 disposed substantially perpendicularly to the left and right sides of the tape drive mechanism 4 of the apparatus. The protrusions 8 and 9 of the router 7 are slidably engaged with the guide grooves 10 and 11 provided on the vertical support plate 5.6, and the protrusion 8 is attached to the vertical support plate 5.6 and is slidably engaged with a groove 14 on the drive arm rotatably supported on the shaft 12.

The drive arm is configured to rotate about a shaft 12 by rotation of a cassette holder drive motor (not shown). When the drive arm 1 rotates counterclockwise in Figure 1, the cassette holder 7 is guided by the grooves 10 and 11 and moves horizontally at first and then vertically to drive the tape as shown by the dotted line in Figure 1. Approach mechanism 4 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 16 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.

As shown in FIG. 6, 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 2o, so that the rotation of the pinion 16 eventually causes the upper half 21 to
1 goes up and down.

Similarly, a pinion 2 is provided on the shaft 23 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 part of the adapter 20.
27 is mounted, so when the pinion 24 rotates, the elevator 26 and the lower part 727 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 Fig. 3, the gear 28
rotates clockwise, and when the adapter 20 moves to the right in FIG. 3, the gear 28 rotates counterclockwise (F).The internal structure of the adapter 20 is VH3.
The VH8-G cassette adapter is well known, so I will not go into details, but as shown in Figure 5, when the gear 28 rotates clockwise, the rotating arm 29
The magnetic tape 34 is pulled out from the small tape cassette j by the upper pull-out pin 3o and the turn 94, -7 by the pull-out pin 32 on the movable arm 31. It is configured to form a similar tape loop 35.

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 magnetic tape is stored in the small tape cassette by driving the take-up reel 37 inside the small tape cassette.

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. Lower half 27 ld above 10,,-.

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, 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 420, and then the upper half 21 and the lower half 27 are separated.
721 and the lower half 27 are combined, the pull-out pin 3, 0.32 is 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 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 42
When the upper half 21 faces the cassette insertion slot 3 shown by the dashed line, the rear wall 60 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. Tape cassette holder 4
There is no possibility of erroneous operation of inserting a small tape cassette or other object into a space other than 2.

FIGS. 7 to 9 are plan views of the states shown in FIGS. 2 and 3 viewed from above the apparatus.

The latch 53 is supported by the upper half 21 so as to be slidable on shafts 51 and 52 installed on the upper half 21.

The first protrusion 55 of the latch 53 can selectively engage with the engagement part 56 of the elevator 18, and the second protrusion 78 of the latch 53 can selectively engage with the engagement part 76 of the cassette holder 7. There is. The pin 54 installed in the latch 53 is in the state shown in FIG. 2, and engages with the groove 75 of the launch drive member 59, which is installed in the upper plate 77 and is slidably supported by the shaft 57.58. I'm going to be like that. Pin 5 is still in the state shown in Figure 1.
The height 4 is such that it does not interfere with the mounting operation of the tape cassette by the cassette holder 7. Latch drive member 5
Reference numeral 9 denotes a latch which is configured to be able to reciprocate between the state shown in FIG. 8 and the state shown in FIG. 53 also reciprocates to selectively engage with the elevator 18 or the cassette holder 7.

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

When installing the standard tape cassette 45 into the device A
I will explain. In FIG. 1, when a standard tape cassette 45 is inserted into the cassette insertion slot 3 as shown by the dashed line in the same way as in the conventional case, a switch (not shown) is turned on, the cassette holder drive motor starts, and the drive arm 13 In Figure 11, it rotates counterclockwise and reaches the position indicated by the dotted line, so the cassette holder 7
The standard tape cassette 45 held in the cassette holder 7 slides guided by the grooves 10° 11 and moves to the position indicated by the dotted line in FIG. As shown in , it is installed in the same way as the 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. 2, the cassette boulder 7 is in the middle 13A.

The cassette holder drive motor (not shown) rotates to move the cassette holder 7 to the open position, and moves the cassette holder 7 to a position where the adapter 20 and the cassette holder 7 do not overlap in plane, as shown in FIG.

After that, the motor (not shown) rotates, the pinion 16 rotates counterclockwise in FIG. 2, and the elevator 18 and the upper part of the adapter 2o...-721 also rise to the position shown in FIG. 2 via the rack 17. do. 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 via the lever 25 to the position shown in FIG. At this time, the pin 54 of the latch bean engages with the groove 75 of the latch drive member, mini.

The height positional relationship between the upper half 21 and the lower half 27 shown in FIG. 2 is as shown in FIG. It is at a height position (7) where they do not touch each other.

In addition, the small tape cassette holder 42 is in the state shown in FIG.
.

It was moved to the right side in FIG. 2 within the upper half 21 in order to receive it. Of course, as can be seen from FIG. 6, the cassette insertion opening 3 is substantially covered by the rear wall 5o of the upper half 21 except for the small tape force center holder 42, so that the insertion position of the small tape cassette 3 is can be easily distinguished.

In the state shown in Fig. 2, 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. 2 while holding the small tape cassette holder, 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. 2, and the upper half 21 and the lower half 27 are combined as shown in FIG. 3. At this time, the pull-out pins 30 and 32 are inserted into the back side of the magnetic tape 34 of the small tape slot 33 and the -7 slot. The external dimensions of the combined adapter 20 are still the focusing type tape cassette 45.
Since the external dimensions of the cassette holder and the drive motor (not shown) are approximately the same, the cassette holder and drive motor (not shown) are reversed in this state. When the drive arm 13 is rotated clockwise in FIG. 3, the adapter 20 is inserted into the cassette holder as shown in FIG. FIG. 8 is a plan view showing this state. In Figure 8,
When the motor (not shown) rotates, the launch drive member slides to the left in FIG. The latch 53, which is engaged with the launch drive member 59 through the pin 54, also slides to the left in FIG. The protruding portion 78 of the cassette holder 7 engages with the engaging portion 76 of the cassette holder 7, resulting in the state 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. 3, the cassette holder moves in exactly the same manner as when the floating tape cassette 45 is mounted. This time, the cassette holder 7 contains a small tape cassette and holds an adapter 20, 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 to the left in FIG. 3 from the state shown in FIG. Therefore, the magnetic tape running path on the front side of the adapter 9 before installation is approximately the same as the tape running path of a standard tape cassette, and even if the adapter 20 is installed in the tape drive mechanism 4, the side pipe problem will not occur. Lick.

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 mentioned above, the magnetic recording/reproducing apparatus according to the present invention can use both standard tape cassettes and small tape cassettes.

In addition, in the above embodiment, the magnetic recording/reproducing device is based on theory 17.
.

However, it is obvious that the present invention can be similarly applied to an apparatus that records and reproduces news on a tape mechanically, electrically, or optically by uniform means.

However, the same effect can be obtained by attaching the standard tape cassette or adapter and the tape drive mechanism relative to each other, or by moving the standard tape cassette or adapter but moving the tape or drive mechanism more. is self-evident.

Effects of the Invention As described above, the present invention includes: 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;
a small tape cassette holder that holds a small tape cassette inserted from a tape cassette insertion slot; Tape cassette or 1 is an adapter holding a small tape cassette 187
1, -7 A mounting means for mounting either one of them to the tape drive mechanism, a first position that does not interfere with the mounting operation of the large tape cassette by the mounting means, and a second position where the small tape cassette holder faces the tape cassette insertion slot. By having an adapter moving means for reciprocating the adapter and an engaging means for selectively engaging the adapter with the cassette holder or the adapter moving means, standard tape cassettes and small tape cassettes can be inserted into the cassette insertion slot. It is possible to realize a cassette mounting device that can be mounted on a tape drive device simply by inserting the cassette into the tape drive device.

Furthermore, since the adapter can be selectively engaged with the adapter moving means and the cassette holder, a standard cassette and a small cassette can be mounted on the tape drive device using the same cassette mounting means, making it possible to downsize the device. It can also be realized at low cost.
