Title:
METHOD AND DEVICE FOR PERMITTING LEGAL RECYCLE BY PREVENTING ILLEGAL RECYCLE OF DISPOSABLE CAMERA
Document Type and Number:
Japanese Patent JP3499637
Kind Code:
B2
Abstract:
PURPOSE: To permit the legal recycle of a camera when one roll of film is exchanged with the other film by recovering a disabled function and permitting the legal recycle of the camera when a reset code is inputted to the camera.
CONSTITUTION: Concerning a counter 55, a shutter/flash synchronizing switch 53 is closed for photographing by a shutter blade 7, and the count of number value of remaining value of one roll of film is decreased just for '1'. When the counter turns to '0', a flash charging circuit 47 is disabled, and the camera can not be illegally recycled. When one roll of non-exposed film is loaded into the camera 1, the reset code selected by an IC 51 is inputted to the IC. The reset code inputted to the IC 51 is coincident with the recovery code of the IC. As a result, the counter 55 increases the selected number of photographed pictures from '0' and the flash charging circuit 47 recovers its function.
