The rotation can be controlled by a driving gear 15 that is driven to rotate. Timing pulley 17
Is rotated by an external force, the timing belt 20 is rotated.
And the core 2 inscribed in a part of the timing belt 20
1 is also rotated.

Next, the operation of winding the film 1 by the magazine of this embodiment will be described. First, the film 1 is inserted from the film guide 40 toward the timing pulley 17 while rotating the timing pulley 17 and the timing belt 20 in the direction of the arrow in FIG. Film 1
Is pulled between the timing belt 20 on the timing pulley 17 and the core 21 and is taken in the tangential direction of the timing pulley 17 and the core 21. Then
The entire film 1 is wound around the outer periphery of the core 21,
It is stored between the outer peripheral surface of the core 21 and the timing belt 20 wound on the core 21. further,
When subsequent films are inserted one after another following the wound film 1, all of the films are stored between the core 21 and the timing belt 20. In this case, the roll body R sandwiched between the core 21 and the timing belt 20 is also rotated via the timing belt 20 by the rotating action of the timing pulley 17. By the above operation, as shown in FIG. 5, on the outer periphery of the core 21, a roll body R composed of an aggregate of wound films is formed. In this roll body R, the first inserted film 1 is always
(From the innermost position of the roll R and in contact with the core 21) to the last inserted film (the outermost position of the roll R and in contact with the timing belt 20). The order of insertion is maintained.

As described above, the pair of timing pulleys 17 and 18 hold the roll R obtained by winding the film 1 and simultaneously rotate the roll R. Further, since the roll body R is always pressed against the pair of timing pulleys 17 and 18, even if the outer diameter of the roll body R changes according to the total length of the film to be stored, the film at the film entrance and exit of the magazine 11 can be removed. The attitude, that is, the angle at which the film 1 enters the film guide 40 as a film passage path and the angle at which the film 1 is discharged to the film guide 40 do not change. Further, the roll R of the film 1 sandwiched between the timing belt 20 and the core 21 has a magazine 11 irrespective of the outer diameter of the film roll R which changes according to the amount of the film 1 to be stored.
The film 1 can be stably held in the inside. Even when the roundness of the outer shape of the roll R is low, the roll 1 is constantly pressed centrifugally by the timing belt 20 from the outer periphery of the roll R.
It can be held stably in the interior. In addition, the film 1 is not directly pressed by a roller member or the like in order to maintain the shape of the roll body R of the film 1, so that the film 1 is
There is little possibility that friction occurs between the magazine 11 and the film 1 when the film 1 is taken in and out. Then, the film 1 is stored by rotating the roll body R of the formed film with a force from the outer peripheral side thereof.
Unlike the method in which the film 1 is wound around the spool by forcibly rotating the spool with external force, the film 1 is squeezed from the inside by the spool, causing a circumferential displacement with friction between the film surfaces. Absent.

As shown in FIG. 5, when the amount of film to be stored is large and the total length is long, the outer diameter of the roll R is also increased. As a result, a larger portion of the timing belt 20 is It will be wound. However, the extra length of the timing belt 20 is supplied by the bracket 24 and the tension pulleys 22a and 22b being separated from the film guide 40 against the tensile force of the coil spring 26 having the urging mechanism. A stable tension can always be maintained without excessive tension acting on the timing belt 20.

The bracket 24 is provided with a pair of arms 27a and 27b so as to be swingable, and dancer rollers 28a and 28b are rotatably provided at the respective tips of the arms 27a and 27b. Have been. The dancer rollers 28a, 28b project from the bracket 24 toward the film guide 40, respectively. The dancer rollers 28a and 28b are caused to contract by the biasing force of the tension coil springs 29a and 29b provided between the bracket 24 and the arms 27a and 27b. R
And always exerts a pressing force on the pair of timing pulleys 17 and 18 regardless of the diameter of the roll body R.

That is, the dancer rollers 28a and 28b
At the moment when the rotation operation of the roll body R is started and stopped by the timing pulley 17 and the timing belt 20, the core 21 or the roll body R integrated with the core 21 is likely to be swung or shaken due to its own weight. Can be minimized. Furthermore, the dancer rollers 28a and 28b can reduce the tension required for the timing belt 20 by bearing a part of the function of holding the roll body R in a circular shape mainly carried by the timing belt 20. .
