Abstract

PURPOSE:To miniaturize a device on the whole by putting all curtains by one operating member. CONSTITUTION:When an operating lever 3 in a set state is swiveled to right by a driving member, an operating member 5 is guided in the long-sized groove 2a of a guide plate 2 because of the fit-in relation between a pin 5a and a long- sized groove 3a to move linearly to the lower part in the figure. A slit-forming curtain 6 is fitted directly to the operating member 5, so it while its attitude is held moves down in parallel. Although auxiliary curtains 7-9 may move in parallel by their weights nearly holding their attitudes as the operating member 5 moves, they move in parallel while nearly holding their attitudes by being pushed at least after the lower end surface of the operating member 5 comes into contact with lower internal surfaces of respective long-sized grooves 7a-9a. Then, the end surfaces of the respective curtains 6-9 meet the stopper part 2c of the guide plate.
