Next, the regulating means will be explained using FIG. 4.

The restriction arm 35 is rotatable around a support shaft 36, and is provided with a lock portion 37 and a release portion 38. Although not shown, it is biased clockwise by a biasing spring, as shown in FIG. A regulating arm 35, a support shaft 36, and a biasing spring constitute a regulating means. Further, the chassis 31 is provided with a tape drive means 39 for driving the magnetic tape of the standard tape cassette 04 or the small tape cassette 103 (FIG. 6). Vertical support plate 14
A wiper arm 40 is also provided via a synchronizing shaft (not shown), and is adapted to drive the protrusion 13 of the holding means 9 (FIG. 5).

Next, the operation will be explained. First, the operation of inserting the standard tape cassette 104 into the apparatus 1 will be explained. When the standard tape cassette 104 is selected using a cassette selection button (not shown), the motor 26 rotates and the device 1
The state will be as shown in the figure. That is, wiper arm 15
has moved the holding means 9 to the first cassette insertion position. At this time, since the restricting means is in a position where it does not interfere with the rotational movement of the second covering means 3 as shown in FIG. 2, the second covering means 3 is in a rotatable state. In addition, the suppression member 2
9 is retracted at a position that does not interfere with the operation of mounting the standard tape cassette 104 onto the apparatus 1.

When the standard tape cassette 104 is inserted into the cassette insertion slot 2 in this state, the first covering means 4 and the second covering means 3 are rotated, and the tape cassette 104 is mounted in a predetermined position on the holding means 9. Then, the motor 26 starts rotating in the forward direction, and the cam gear 24 rotates. Since the cam follower 23 provided on the slide lever 19 moves according to a cam groove (not shown) provided on the cam gear 24, the slide lever 19 moves in the direction of the arrow in FIG. 2 and rotates the wiper arm 15 clockwise. make it move. Therefore, the standard tape cassette 104 held by the holding means 9 moves along the guide grooves 7 and 8, and the fourth
The attachment to the tape driving means 39 as shown in the figure is completed. Additionally, a cam follower 41 provided on the suppressing member 29
is a cam groove (not shown) provided on the back surface of the cam gear 24
Therefore, the suppressing member 29 rotates slightly before the standard tape cassette 104 is completely attached to the tape drive means 39, and moves the standard tape cassette 104 to the chassis 31.
press against. In this way, the standard tape cassette 104 can be mounted on the tape drive 1 means 39, making it possible to record on and reproduce from the magnetic tape.

Next, the ejection operation of the standard tape cassette 104 will be explained. When a discharge command is sent to the device 1 in the state shown in FIG. 4, the motor 26 starts to rotate in reverse, and the -14 to cam gear 24 also starts to rotate in reverse. Then, the pressing member 2
9 begins to rotate, and then the slide lever 19 moves to rotate the wiper arm 15 and move the standard tape cassette 104 held by the holding means 9 to the position shown in FIG. At this time, although not shown, a covering means release mechanism releases the first covering means 4 and the second covering means 3.
is released to a position where it does not interfere with ejection of the standard tape cassette 104. In the state shown in FIG. 2, the standard tape cassette 104 can be grasped and removed from the apparatus 1. When inserting the standard tape cassette 104 into the device 1 or removing the standard tape cassette 104 from the device 1, the cassette gripping margin is the length Ll in Fig. 2, which is long enough to allow easy operation. ing.

Next, the operation of inserting the small tape cassette 103 into the apparatus 1 will be explained.

When the small tape cassette 103 is selected using a cassette selection button (not shown), the motor 26 rotates in the forward direction, and the apparatus 1 is placed in a state as shown in FIG. That is, wiper arm 15
The holding means 9 is moved to a second cassette insertion position which is outside the device 1 from the first cassette insertion position.

At this time, since the holding means 9 comes into contact with the release part 38 of the regulation arm 35, the regulation arm 35 rotates around the support shaft 36 against the biasing force of the biasing spring (not shown), and the locking part 37 is rotated. Since it comes into contact with the second covering means 3 as shown in FIG. 3, the second covering means 3 is in a state where it cannot rotate.

Further, the pressing member 29 is retracted to a position where it does not interfere with the operation of mounting the small tape cassette 103 onto the apparatus 1. When the small tape cassette 103 is inserted into the cassette insertion slot 2 along the cassette guide groove 5 in this state, the first covering means 4
is rotated and attached to a predetermined position on the holding means 9. The subsequent operation is exactly the same as when using the standard type tape cassette (104), so a description thereof will be omitted.

When inserting the small tape cassette 103 into the device 1 and when removing the small tape cassette 103 from the device 1,
The gripping margin for the cassette is the length L2 in FIG. 3, which is long enough to allow easy operation.

Furthermore, even if an attempt is made to insert the small tape cassette 103 into the device 1 without aligning it with the cassette guide groove 5, the second covering means 3 is prevented from rotating by the regulating means. Accidents in which the device 1 cannot be inserted into the device 1 and is attached to a location other than the predetermined position of the holding means 9 can also be prevented.

In this embodiment, the first covering means that substantially covers the insertion position of the small tape cassette is provided, but the present invention is not limited to this, and only the second covering means may be provided.

Effects of the Invention As described above, the present invention provides a holding means for holding a standard tape cassette or a small tape cassette, and a first cassette into which the standard tape cassette can be inserted into a predetermined position of the holding means from a cassette insertion opening. The holding means is moved back and forth between the insertion position, a second cassette insertion position where the small tape cassette is inserted into a predetermined position of the holding means, and a mounting position where the standard tape cassette or the small tape cassette is mounted on the tape drive means. Since the device is equipped with a moving means, not only standard tape cassettes but also small tape cassettes can be inserted into the device, and when removing the cassette from the device, there is plenty of room to grip the cassette, making the device extremely easy to use. can be provided.

Further, the holding means is movable between an operating position that substantially covers a portion of the cassette insertion slot other than the portion into which the small tape cassette is inserted and a non-operating position that does not prevent the insertion of the small tape cassette into the holding means. Since the regulating means is provided to fix the covering means in the operating position when it is in the second cassette insertion position, the position at which the small tape cassette is inserted into the device can be made clear, and the regulating means regulates the covering means in the operating position. Therefore, even if an attempt is made to insert the small tape cassette into the wrong place, the cover means will not open, and an accident such as inserting the small tape cassette into a place other than the predetermined part of the holding means can be prevented.
