JPS5511219A - Rolled film draw-out device of patrone - Google Patents

Abstract

PURPOSE: To readily and surely draw out the leading end of the film in a patrone through simple operation by holding various parts such as guide plate, draw-out plate, knob, etc. within the body of the draw-out device.

CONSTITUTION: After a draw-out plate 5 is extended up to the leading end position of a guide plate 4 by operating a knob 7, both of these are pushed in until the end part 2A of the body 2 of a draw-out device 1 abuts against the input end 10A of a patrone 10. Next, with the top face of a stopper 3 and the bottom end of the patrone being gripped with one hand, the knob 7 is operated by the other hand to position the leading end 5A of the draw-out plate to the neighborhood of the inlet of the patrone. Since the leading end 5A is curved downward, a space 11 is formed between the same and the guide plate and therefore if the shaft 12 of the patrone is turned counterclockwise, it turns out that the end part 8A of the film positions between the end part 5A and guide plate 4. At this point, the knob 7 is moved left without rotating the shaft 12 to insert and engage the pawl 5C of the draw-out plate in the perforations of the film 8. Hence, if the body 2 is pulled apart from the patrone, the film 8 is surely drawn out.
