Abstract
PURPOSE: To surely perform moving of belt material at a constant speed by providing a recess for releasing the contact of capstan and gear to the gear provided coaxially to the pinch roller and delaying the pressure-contact timing of the pinch roller with respect to the start timing of the motor.
CONSTITUTION: In the operating device of a pinch roller with moves the recording belt material of a cine camera together with a capstan shaft, a pinch roller is freely rotatably mounted to the shaft 20 at one end of the moving member 19 and a notched gear 25 having a toothless recess 25 at a part is fixed to the shaft 20. When the moving member 19 is turned about a fulcrum axis 21 at the time of moving the belt form member shown by a dot-dash line, the pinch roller 18 moves right upward. This movement causes a switch 30 to go ON to start a motor 12. Then, a flywheel 11, capstan shaft 15 and gear 16 rotate, causing the notched gear 25 and gear 16 to intermesh and rotate. When the toothless recess 25a comes to oppose to the gear 16, the pressure contact blocking state of the capstan 15 and pinch roller 18 is released and both make pressure contact with each other and multually rotate, thereby moving the belt material at a constant speed.
