点があつた。 In general, in a so-called front loading type tape storage case mounting device in which the tape storage case is inserted through the insertion slot on the front of the recording/playback device, the tape storage case (hereinafter referred to as a cassette) after recording or playback is ejected. This causes the cassette to be pushed out to an eject position that protrudes beyond the front of the device, ie, to a position where it can be easily grasped when taking the cassette out of the device. In the conventional device, a rotary lever is rotatably supported on both sides of the rear of the holder, and an elastic member is provided at the rear of the rotary lever to urge the rotary lever to rotate in the eject direction. During operation, the end of the rotary lever slides against the cam portion facing the side surface of the holder and rotates, pushing out the cassette as the holder moves. For this reason, a space is required for attaching the rotation lever and the elastic member to the rear of the holder and for rotating the rotation lever, and there is a drawback that the device cannot be made smaller by this space.

Further, the rotating lever 9a is supported within the recess of the side plate 3a and is hidden within the thickness of the side plate 3a. Therefore, the holder 1 does not require extra space for the rotation lever 9a, and is made more compact. The rotating lever 9a includes a leaf spring portion 9B having a sliding contact portion 9A at its tip and bending in the directions of arrows Z 1 and Z 2 , and an arm portion 9D having an engaging portion 9C at its tip. Further, the sliding contact portion 9A of the rotary lever 9a has a sliding contact pin 9A- 1 that projects outward with the plate spring portion 9B as a boundary, and a pressing pin 9A- 2 that projects inward. Incidentally, only the sliding pin 9A- 1 of the rotary lever 9a protrudes outward from the side plate 3a. The engaging portion 9C of the rotary lever 9a engages with the engaged portion 7B of the push-out member 7a that extends vertically from the through hole 3A of the side plate 3a. still,
A through hole 3B is provided in the side plate 3a at a position facing the sliding contact portion 9A of the rotating lever 9a. Therefore, as will be described later, when the holder 1 moves to the mounting position, the through hole 3B is bent by the plate spring part 9B of the rotating lever 9a, so that the pressing pin 9A- at the tip of the plate spring part 9B is bent.

It descends to the mounting position shown by . Furthermore, the sliding contact pin 9A- 1 of the sliding contact portion 9A that protrudes from the side plate 3a of the holder 1 toward the support plate 21a moves along the groove 12a provided inside the support plate 21a, and engages with other members. Therefore, the cassette 2 will not be pushed out of the holder 1 without permission. The pins 18a to 20a of the side plate 3a slide in the guide grooves 22a to 24a of the support plate 21a, and the cassette holder 1 moves stably while maintaining a horizontal state. When the cassette 2 is lowered to the mounting position, the cassette lid 37 is relatively pushed up by the rotation of the cassette lid push-up lever 40. When the cassette 2 descends onto the reel stands 38a, 38b and reaches the mounting position, a motor stop switch (not shown) cuts off the power to the motor 27, and the motor 27 stops.

When the operator performs an eject operation, the motor 27 rotates in the opposite direction and rotates the pinion 36a counterclockwise via each gear. Therefore, the holder 1 is driven by the pinion 36a that meshes with the vertical portion 17a- 2 of the rack gear 17a, and moves upward from the mounting position (indicated by the dashed line in FIG. 2) to the raised position, and then to the insertion position (FIG. 2). (indicated by the middle two-dot chain line).

了して減速されることになる。 After the holder 1 passes through the raised position, the sliding portion 9A of the rotating lever 9a reaches the cam portion 11a provided inside the support plate 21a. At this time, cassette 2
The rear portion 2B of the device has not yet passed through the insertion port 13 and is inside the device. As shown in FIG. 4C and FIG. 5D, as the holder 1 moves in the direction of the arrow
The sliding contact pin 9A- 1 connects to the cam portion 11 without bending to B.
Slide contact a. Therefore, as shown in FIGS. 6A and 6B, while the holder 1 passes through the range l, the sliding contact portion 9A
slides on the cam portion 11a to rotate the rotary lever 9a clockwise, and at the same time separates the pressing pin 9A- 2 from the switch 10a to return it to the OFF state. By rotating the rotating lever 9a in the clockwise direction, the engaging portion 9C at the tip of the arm portion 9D pushes the engaged portion 7B of the pushing member 7a in the direction of arrow X2 . Therefore, the pushing member 7a is pushed in the direction of arrow X2 by the elastic force of the rotating lever 9a and the spring 8a, and the contact portion 7
A pushes out the cassette 2 inside the holder 1 in the direction of the eject position. At this time, the rear part 2 of cassette 2
B passes through the insertion port 13 from inside the recording/reproducing device and is pushed out from the front of the device. Rear 2B of cassette 2
When the holder 1 passes through the insertion opening 13, the holder 1 is being driven by the pinion 36a and is moving in the direction of arrow X2 .
Therefore, the cassette 1 is once accelerated by the moving speed of the holder 1 and the pushing operation of the pushing member 7a. As shown in FIGS. 4D and 5E, when the sliding pin 9A- 1 of the rotating lever 9a finishes sliding on the cam portion 11a, the pushing out operation of the cassette 2 by the pushing member 7a is completed, and the pushing out of the cassette 2 is completed. The eject movement speed becomes the same as the movement speed of the holder 1 again. At this time, the rotating lever 9a rotates counterclockwise due to its own weight, and the switch 10a is in the OFF state.
A pressing pin 9A- 2 is placed on top. Insertion port 13
After passing through the cassette 2, the pushing operation is completed and the cassette 2 is decelerated.

At the eject position (indicated by the dashed-dotted line in Fig. 3), the cassette 2 protrudes from the front surface of the device by the stroke pushed out by the abutting portion 7A of the pushing member 7a from the insertion position (indicated by the dashed-double line in Fig. 3). This is a position where it is easy to grasp the cassette 2 when removing it from the device.

In the moving tape storage case mounting device, a cam portion provided on the recording/playback device main body facing the side surface of the holder;
A rotating mechanism that has a sliding part that slides on the cam part at the end of one arm, an engaging part at the end of the other arm, and is supported on the side so that it can rotate in a plane parallel to the side surface of the holder. A pusher that is movable in the insertion/removal direction of the tape storage case and has a lever, a contact part that contacts the front part of the tape storage case, and an engaged part that is engaged with the engagement part of the rotating lever. During the eject operation, the sliding part of the rotary lever slides against the cam part and the rotary lever rotates, and the engaging part engages with the engaged part to move the push-out member and make contact. Since the tape storage case is configured to be pushed out to the eject position by the part, the installation space for a rotating lever, etc., which conventionally required the tape storage case stored in the holder to be provided further to the rear of the holder, is eliminated. Therefore, the space required for the holder to move from the insertion position to the mounting position can be reduced, and the entire device can be made more compact by eliminating unnecessary space.Moreover, the rotating lever can be mounted on the side of the holder. By attaching the holder so as to be included therein, the holder does not become larger in the side direction, and furthermore, the tape storage case can be smoothly pushed out to the eject position during the eject operation.
