Title:
CAMERA
Document Type and Number:
Japanese Patent JP3472012
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a camera using a thrust type film cartridge.
SOLUTION: The camera is provided with a fork gear 10 for driving the spool 2 of the cartridge 1, a sector gear 6 connected to a door driving shaft 4 for driving the film entrance door 3 of the cartridge 1, a cam plate 31 as an interlocking means for controlling the interlock and non-interlock of the gears 10 and 6 and an operating member 27. The spool 2 and the door 3 are driven with the same drive source. The spool 2 is rotated when the rewinding of the film is completed and then, the door 3 is closed, so that the rotational stopping position of a data disk 16 (fixed to the spool 2) in the cartridge 1 is shifted. At this time, patterns shifted at a fixed angle are formed two by two for each film state display, for instance, patterns 13aa and 13ab, on a phase printed board 13 as a rotational stopping position detecting means for the fork gear 10. Then, the door 3 is closed when the rewinding of the film is completed and then, the fork gear 10 is turned from one of two patterns to the other.
