FIG. 6 shows a side view of the cassette mounting device in a state where the front of the cassette holder 19 is slightly raised above the horizontal. In FIG. 5, 23 is an engagement plate, and the support shaft 10
It is rotatable around c, and has a notch 23b at its tip and a bent portion 23a at its rear end, which abuts the end surface of the guide arm 10. 24 is a cassette lock lever, and a support shaft 24a set on the cassette holder 19 is inserted into the cassette lock lever.

Place the other end into the cassette holder 19.
It is biased clockwise by an attached tension spring 26. 24b is a pin installed in the lock lever 24, and is engaged with the notch 23b.

24c is a convex portion at the tip of the cassette lock lever 24 for preventing the cassette from slipping out. 26t11 This is a hole provided in the cassette holder 19 and the deformation gear 9, and the pin/
24b and the notch 23b are engaged with each other.

The operation of the cassette loading device configured as above will be explained.

First, FIG. 1 shows a side view of the cassette mounted on the reel stand. In FIG. 1, the relay gear 3 rotates clockwise due to the rotation of the drive motor (not shown), and this rotational force is transmitted to the drive gear 7 via the connecting gear 4, the relay gear 6, and the relay gear 6. . As the drive gear 7 rotates clockwise, the deformation gear 9 moves forward while being kept in mesh with the drive gear 7 by the guide roller 8.

At this time, the deformation gear 9 and the cassette holder 19 are supported by the support shaft 10c of the guide arm 10. Furthermore, the engagement between the slide pin 16 and the slider 15 guides the cassette holder 19 so that the bottom surface of the cassette 17 is vertical until the cassette holder 19 moves approximately 20 all forward. The guide arm 1o moves forward in the axial direction of the reel stand while being guided by the long holes 13 and 14. After such action,
The state shifts to the state shown in FIG.

In FIG. 3, the cassette 17 has been removed from the reel stand 22. Also, the guard panel 18 is closed,
. co. 1 Yu, □ Ia 7 A U I engage on pitch line 9b of JA 9. When the drive gear 7 further rotates clockwise, the pitch circle 9c of the deformation gear 9
They engage at the top, and the cassette moves to the state shown in Figure 4. At this time, since the inner wall surface 9a of the deformation gear 9 is restricted from contact with the guide roller 8, the operation proceeds while the teeth of the deformation gear 9 and the drive gear 7 are maintained in mesh.

When the drive gear 7 further rotates clockwise, the drive gear 7
are engaged on the pitch circle 9d of the deformable gear 9, and the front of the cassette holder 19 moves to a state raised about 16 degrees above the horizontal, as shown in FIG. In this state, it is possible to insert and remove the cassette 17, and the cassette 1
7 by hand in the direction of the arrow 3o, and when inserting it, move it in the direction of the arrow 31. Also, when moving from FIG. 4 to FIG. By coming into contact with the end surface, the engagement plate 23 moves the cassette holder 1 around the support shaft 10c.
Rotate clockwise relative to 9. Therefore pin 24
By engaging b and notch 23b, the cassette lock lever
It rotates counterclockwise relative to the 24U cassette holder 17 about the support shaft 24&. Due to this,
The convex portion 24 is removed from the cassette 17, resulting in the state shown in FIG. Note that when the guard panel side of the cassette 17 is raised above the horizontal level, the convex portion 24 has rotated approximately 100 degrees clockwise relative to the cassette holder compared to the state shown in FIG. 19 to prevent it from slipping out during the transition. In the above description, the operation from the cassette loading position to the cassette insertion position has been described, but the operation from the cassette insertion position to the cassette loading position is the opposite of the above operation and is exactly the same. 1 and 3 to 6, the same components as shown in the respective figures are driven by the connecting shirt 4a and perform similar operations.

As described above, according to this embodiment, the cassette holder 190
A guide arm 1o that rotatably supports the guide arm 1o and can be moved back and forth is provided on both sides, and a deformation gear 9 fixed to the cassette holder 19 and a drive gear 7 that meshes with the deformation gear 9 and drives the deformation gear 9 are provided. When inserting the cassette into the cassette holder, the cassette tape drawer opening can be inserted from the opening with the opening slightly lower than horizontal, and after the cassette holder is moved, the opening is positioned at the top; That is, the cassette is in an upright state, and moreover, it becomes possible to see through the cassette normally from the front.

Effects of the Invention As described above, according to the present invention, when inserting a cassette into a cassette holder, it can be inserted from the opening for drawing out the tape, and when the cassette is mounted on the reel stand, the cassette can be inserted from the opening for drawing out the tape. is located at the top, and not only can you see through the cassette from the front when the cassette is upright, but you can also see the 9 characters and labels written on the cassette normally, giving it a high quality product. It's a dog.
