bite into.

The operation of the above-mentioned cassette loading device 1 will be explained using FIGS. 10 to 14.

First, in FIG. 10, the tape cassette 5
1 into the cassette holder 2 through the cassette insertion opening 40, the lid 51a of the tape cassette 51 pushes the cassette pressing member 31d, and the cassette pushing member 31 moves in the opposite direction (C in the figure). direction), and the tape cassette 51 is held at the cassette hold position shown in FIG. Such tape cassette 51
During operation until is held in the cassette hold position,
Since the rear part of the claw part 3c of the side frame 3a and the cassette side of the claw part 31c of the cassette pushing member 31 come into contact,
The cassette holder 2 is moved horizontally by a predetermined distance. When a detection device (not shown) detects that the tape cassette 51 is held at the cassette hold position, the drive motor 6 rotates in the direction of loading the cassette 51, and this rotational force is generated as shown in FIG. Worm 7 → Worm wheel 8 → Gear 9 → Gear 10 → Gear 1
1 → Gear 12 → Right lever 4 via drive gear 13b
b, 5b, and the left drive gear 13a.
The rotational force of the right drive gear 13b is transmitted to the drive gear 13b via the gear 14b, the relay shaft 15, and the gear 14a. As a result, the rotational force of the drive motor 6 in the loading direction is applied to the left and right drive levers 5a and 5b, and the left and right levers 5a and 5b are
The forces a and 5b pull the cassette holder 2 toward the back from the left and right sides via the levers 4a and 4b, and the cassette holder 2 is pulled by the guides of the L-shaped grooves 33 and 34 as shown in FIG.
is moved horizontally in the direction D in the figure.

When the horizontal movement is further completed, the lever 5a,
The force of 5b is applied to the cassette holder 2 via levers 4a and 4b.
14 by pulling the cassette holder 2 downward and vertically moving the cassette holder 2 downward by the guides of the L-shaped grooves 33 and 34.
Set it in the loading position shown. In this case, the lid 51a and the cassette push-out member 31 are rotated by a member (not shown) to a position where the tape is not obstructed from being pulled out from the tape cassette 51.

When ejecting the tape cassette 51,
The rotating shaft 61 of the drive motor 6 rotates in the direction to eject the cassette, and this rotational force is transmitted to the left and right levers 5a and 5b through the same path as described above. The forces of the levers 5a and 5b push the cassette holder 2 upward from the position shown in FIG. 14 via the levers 4a and 4b, causing the cassette holder 2 to move vertically upward. When the vertical movement is further completed, the force of the lever 5 moves the cassette holder 2 via the lever 4 as shown in FIG.
3 in the direction opposite to the direction D in the figure (front direction) to horizontally move the cassette holder 2 to the position shown in FIG. After that, when the cassette holder 2 is moved horizontally, the cassette pushing member 31 is moved as shown in FIG.
The claw portion 31c is pressed by the claw portion 3c, and the cassette pushing member 31 rotates in the forward direction (the direction opposite to the C direction in the figure).
The cassette pressing member 31d presses the lid 51a of the tape cassette 51, and the tape cassette 51 is ejected.

According to this embodiment, since the cassette pushing member 31 can be attached to the cassette holder 2,
The device can be made more compact than the conventional method of attaching the cassette pushing member to the side frame.

FIGS. 15 and 16 show another embodiment of the present invention, with FIG. 15 being an exploded perspective view showing the main parts, and FIG. 16 being an assembled perspective view. The same components as in the embodiment of FIG. 1 are given the same reference numerals.

Cassette loading device 2 of this embodiment
