Title:
ROLL FILM CAMERA
Document Type and Number:
Japanese Patent JP3435342
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a roll film camera provided with a film winding mechanism where film is quickly changed by eliminating the need of the shifting of a spool at the time of changing the film.
SOLUTION: A pair of spool chambers 30 and 40 provided at a camera body 20 are respectively provided with the film winding mechanism 50 where roll film is loaded and the film loaded is wound to the other spool chamber at which the film is not loaded. When new film is loaded at one spool chamber after taking out the film exposed before from one spool chamber at the time of changing the film, the loading of the film is detected by the sensors 35 and 45 provided at each spool chamber, and the winding of the film from one spool chamber to the other spool chamber is executed. Operation to shift an empty spool to the spool chamber on an opposite side is unnecessitated at the time of changing the film, so that the film is quickly changed.
