Abstract

PURPOSE: To facilitate operation, by providing a film passing detection means, and a film end detecting means.
CONSTITUTION: A microswitch 25 is provided in a film send-out guide 23 located between a take-up reel 24 and a stabilizer roller 21, and conductive contact point rollers 11, 12 are provided in the vicinity of a supply sprocket 13. In this setting, upon start of operation of a projector 1, when a film 8 is sent by the supply sprocket and passes through the film send-out guide 23, the microswitch 25 closes to operate a control circuit, thereby exciting a control solenoid to press the pinch roller 22 against the stabiliser 21. At the same time, exciting magnetic head 16 and other parts, the record reproduction state is established. The contact point rollers 11, 12 detect the final end of the film 8 to operate the control circuit, thereby de-exciting the control solenoid 28. At the same time, the supply sprocket 13 is rotated in reverse direction, thus rewinding the film automatically.
