FILM UNIT WITH LENS
Document Type and Number:
Japanese Patent JP3261622
Kind Code:
B2
Abstract:
PURPOSE: To provide a film unit with a lens whose cost is restrained from rising by simplifying the mechanism of a camera or making use of space, which has high reliability on a film counter mechanism by which reuse can be possible and where shutter charging actions are accurately performed.
CONSTITUTION: A sprocket gear 54 is fixed on a cam member 155 fitted in a camera main body 10 through a hole, and the V-shaped groove of the gear at the tip of a cam shaft 56 meshes with the gear of an index board, so that the index board 71 is moved by one frame with the movement of film and a fan-shaped cam part 55B moves a charging lever 61 to perform shutter charging. A projecting part 62D is fitted in a circumferential groove part 72E provided on the index board 71, and an arm 10P provided in the camera main body 10 presses the cam member 155 to the lever 61, whereby actuation is stabilized.
