JPS5560925A - Buffer device - Google Patents

Abstract

PURPOSE: To automatically convey the leading end of a film along the specified path and surely form the loop of the film by providing a film guide member in the buffer chamber.

CONSTITUTION: When the leaking end of a film is sent in the buffer chamber by feed rollers 51, its leading end first contacts a bent part 54 then advances while making contact to the surface of a movable guide member 54 as shown by the broken line C, thus it is surely guided between discharge rollers 52. Hence, if these discharge rollers 52 are beforehand revolved, the leading end of the film is sent out to outside the buffer chamber. When the discharge rollers 52 are stopped after this and the film is further fed into the buffer chamber by feed rollers 51, the loop F' of the film is formed between the rollers 51 and 52. The bent part 54a of the movable guide member is lifted by this loop and moves to the position shown by the broken line 54' and further to the one shown by 54". In this way, the loop of the film may be surely formed.
