In FIG. 1, the support shaft 18a of the driven cam 18 is connected to the driving googly 11 either directly or via a known driving force transmission mechanism (not shown) such as gears. Therefore, when the drive cam 19 is rotationally driven in the opposite direction by the motor 20, the drive cam 19 rotationally drives the driven cam 18, and the driven cam 18 rotationally drives the driving googly 11. Due to the rotation of the driving googly 11, the timing drum 13 is rotated together with the driven googly 12, and at the same time, the cartridge storage box 15 loaded in the holder 14 is rotated.

The motor 20 is fixed at a predetermined location.

FIG. 7 is an enlarged view showing the engagement state between the drive cam 19 and the roller 21 as seen from the direction of arrow C in FIG. 6, and FIG. , the state in which the roller 21 is engaged with the feed groove 22 is referred to as the roller 21
FIG. 7 is a view taken in the axial direction (FIG. 7) in the direction of the arrow.

Note that in these figures, specific rows 221 are given the symbols 21ay21b+21c for ease of explanation. In both of these figures, assuming that the drive cam 19 is rotating in the direction of arrow E, the roller 21
A p 21 b y 21 c moves in the direction of arrow F relative to the cam 19. The operation of these rows 221 a r 2 l b + 21 c is basically substantially the same as that described in FIG. 3 (prior art example) above. However, in the case of FIG. 3, the roller 21 itself is moved in the outer circumferential direction (circumferential direction) of the driven cam 18, whereas in the case of this embodiment, the roller 21 (21a, 21b
, 21c) itself is moved in a straight line in the vertical direction. That is, in FIG.
