Inventor: SAITO TATSUO
IPC: G03B17/00
Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To properly detect a final end of a film at the time of pre-winding.  <P>SOLUTION: A feed detection switch 41 is constituted of a metallic contact piece which is turned on/off by the rotation of a sprocket at the time of feeding the film. Then, a feed signal in accordance with the state of the switch 41 is inputted in a feed detection circuit 45. A monitoring pulse output circuit 46 outputs two kinds of monitoring pulses whose output interval is different. The detection circuit 45 decides the level of the feed signal based on the monitoring pulse and detects the change of the level of the signal so as to detect a feed pulse. At the time of pre-winding, the monitoring pulses are outputted at the intervals of 30msec, and at the time of feeding the film by one frame after pre-winding, the monitoring pulses are outputted at the intervals of 2msec. At the time of pre-winding, the malfunction of the switch 41 caused by vibration is hardly detected. After finishing pre-winding, the film is accurately fed by one frame.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
