摘要:
A camera using films each having a development processing solution in a solution accommodating bag includes rollers feeding photographed film outside of the camera or into an accommodating chamber, a piezoelectric press member held between an electrode and an elastic member also serving as an electrode presses photographed film and spreads development processing solution in the solution bag over an entire exposing portion. A piezoelectric member vibrated by AC voltages applied to the electrode and elastic member reduces a frictional force of the film caused by the press member. The processing solution is heated by vibrating the press member to generate heat. A camera using films each having a development processing solution accommodated in a solution bag includes a follower roller disposed on the upper side of the film, an ultrasonic motor composed of a vibrator on the lower side of the film, a temperature sensor detecting temperature of the ultrasonic motor, a peripheral temperature measuring circuit for detecting a peripheral temperature and a control circuit controlling drive of the ultrasonic motor based on the results detected by the temperature sensor and the peripheral temperature measuring circuit. The ultrasonic motor also serves as a film feed unit for feeding photographed film outside of the camera or into an accommodating chamber, a press unit for pressing photographed film and spreading development processing solution in the solution bag over an entire exposing portion and a heating unit for heating development processing solution before spreading.
