Camera with manual film transport has controller that sets film transport speed from counted pulses and reference pulse count corresponding to predefined film transport length at detected transport speed

摘要

A controller sets the film transport speed from the counted pulses and a reference pulse count corresponding to a predefined film transport length at the detected transport speed. The lever is disengaged from the spool when the reference pulse count equals the counted pulse number. The camera has a transport mechanism that transports an unperforated film when a lever on a winding spool is manually actuated. A pulse generator that outputs pulses during film transport movement and a pulse counter are connected to a controller that sets the film transport speed from the counted pulses and a reference pulse count corresponding to a predefined film transport length at the detected transport speed. The lever is disengaged from the spool when the reference pulse count equals the counted pulse number.
