发明名称 SAFETY DEVICE FOR WINDING OF CAMERA
摘要 PURPOSE:To prevent cutting of a film or breakage accident of a camera by transmitting driving force to a take-up spool according to changing over from a driving power transmission state to a rewinding shaft to a driving power transmission state to a photographing mechanism energizing means. CONSTITUTION:When a rewinding operation member 60 is reset in order to change over rewinding mode to winding mode, a release lever 69 is turned by a spring 71, and one end part 69b thereof is retreated from the operation region of a tightening lever 36; at the same time, a changeover lever 73 is also released of the contact with a pawl part 60c, and a gear 22 moves along a revolving shaft 25 in such a way as to mesh with a gear 23. At this time a slide lever 66 starts moving to reset the members 66a, 66b. Therefore, a clutch lever 55 and a clutch plate 5 as well as a pawl lever 8 and a gear 6 are again engaged, and the transmission of the driving force of a motor to a take-up spool 10 via a gear 4 is made possible.
