    • A camera has a back cover movable between a closed state and an open state to enable a film case to be installed in and removed from the camera. A detector detects the transition of the cover between the closed state and the open state. A data register stores control data, and a control circuit receives the control data from the data register for controlling operation of the camera. The control data is transferred temporarily from the data register to an EEPROM when the back cover makes the transition from the closed state to the open state. The control data is then transferred back from the EEPROM to the data register when the back cover makes the transition from the open state to the closed state. By temporarily storing the control data in an EEPROM when the back cover is open, and transferring the control data from the EEPROM back to the data register when the back cover is closed, the adverse effects of static electricity, external noise or resetting of the control circuit are prevented from disrupting the operation of the camera.

    • A printer includes a tractor unit for feeding continuous form paper, encoders driven in synchronization with the tractor unit, and detecting sensors for detecting the encoders to generate feed pulses at a standard interval. The printer further includes a paper top sensor for detecting a leading edge of the continuous form paper to generate paper top signal and is arranged to control the feed of the paper based on the feed pulse generated after the paper top signal. In order to adjust the printing position on the paper in case where the scanning position is misaligned due to a manufacturing error, the position of the detecting sensors is adjustable with respect to the encoders to compensate for the error. Further, the position of the paper top sensor is adjustable with respect to the tractor unit in order to keep the relationship between the feed pulse and the paper top signal unchanged regardless of the adjustment of the detecting sensors.
