両ガイド３ａ，３ｂの位置決めを為している。 Therefore, according to this embodiment, when the drive motor 12 starts rotating during loading after the cassette is attached, the drive gear 13 and the intermediate gear 11
The loading gear 10 is driven clockwise through. Therefore, the loading gear 1
0 causes the rack plate 6 to slide at a slow speed in the direction of arrow A in the figure, and at the same time rotate the loading disk 5 clockwise at a high speed. As the rack plate 6 slides, the second support block 4
The upper two guides 4a and 4b move in the direction of arrow A while pulling out the tape, thereby winding the tape around one side of the guide cylinder 1, and before the sliding of the rack plate 6 is completed, the second engagement Stop block 15
The second support block 4 is brought into contact with the second support block 4, and when the sliding is completed, the conical notch 4c is formed in the protrusion 15b.
Also, the second upright guide 4a is pressed into contact with the V-shaped notch 15a, so that both guides 4a,
4b, the rack plate 4 is slid extra on the second placement lever 8, and the placement lever 8 is pulled toward the second locking block 15 by the second spring 8b. energize. On the other hand, when the loading disk 5 rotates, it first moves the tape pull-out pin 9a to the outside of the cassette 2, and then the two guides 3 on the first support block 3 move.
a and 3b along the loading disk 5, and winding a tape around the other circumferential surface of the guide cylinder 1, the loading disk 5 is moved.
Before the rotation is completed, the first support block 3 is brought into contact with the first locking block 14, and after the rotation is completed,
In the same manner as the second support block 3, the first upright guide 3a is pressed against the V-shaped notch 14a, and the conical notch 3c is pressed against the protrusion 14b to position both guides 3a and 3b. There is.

できる。 Therefore, the locking blocks 14 and 15 insert the spherical tip protrusions 14b and 15b, whose protrusion amounts are adjusted by the tightening screws 14c and 15c, into the conical notches 3c and 4c of the support blocks 3 and 4. The support blocks 3 and 4 are brought into contact with each other and supported with a small amount of room for rotation up and down and left and right, and the V-shaped notch 14
By regulating the upright guides 3a and 4a with a and 15a, the guides 3a, 3b and 4a, 4b can be reliably supported and fixed when loading is completed.
