Abstract
PURPOSE: To reduce rewinding time and achieve higher rewinding speed by so arranging the device that a rewinding shaft is automatically displaced to the direction for engaging to a patrone winding core while turning at the time of rewinding operation and the specified rewinding speed is obtained immediately after the engagement.
CONSTITUTION: When a rewinding lever 1 is turned left, cam plates 2, 13 rotate to left and SW3 goes ON, causing a motor 27 to run reverse. At the same time, a sliding plate 3 is slided in the right direction by the force of a spring 5 and a detaining pin 6 fits into the spiral 7c of a rewinding shaft 7. A gear 23 is fitted to the driven gear 25 of the motor 27 by levers 14, 15, 16, 19, whereby the rewinding shaft 7 is turned clockwise. The shaft 7 is pushed upward by the spiral shaft 7c and a rewinding coupler 12 engages to the pawl part of the winding core on the camera body side while turning. In an engated state, the detaining pin 6 goes from the spiral groove 7c further to the bottom face of the shaft 7, causing the winding core of the film patrone and rewinding coupler to be engaged by the spring 11. The rewinding force of the shaft 7 is then transmitted to the winding core and the rewinding of the film is started.
