Abstract: An electronic timepiece has a thermoelectric element for generating an electromotive force in response to a temperature difference thereacross. A booster circuit boosts the electromotive force generated by the thermoelectric element. A storage mechanism stores electrical power utilizing the electromotive force boosted by the booster circuit. A power monitoring circuit monitors the electromotive force boosted by the booster circuit to detect whether the boosted electromotive force is lower than a threshold value. An oscillation circuit is driven by electrical power stored in the storage mechanism. A dividing circuit frequency-divides a signal output by the oscillation circuit. A display mechanism is driven by a display driving circuit to display time in accordance with an output signal from the dividing circuit. A display drive controlling circuit stops operation of the display driving circuit when the power monitoring circuit detects that the boosted electromotive force is lower than the threshold value.

Abstract: In a light emitting indicator drive circuit which supplies a current to display elements different in display areas, a current control circuit controls the supply current of a constant-current source which is caused by a p-channel MOS-FET which supplies a current to a display element. The current control circuit controls the off-operation of the FET. A signal processing circuit calculates the deterioration data from a deterioration detecting circuit and saved segment area data to decide a supply current value to display elements as a result of the arithmetic operation. With the above operation, a difference in luminance between the display elements and the degradation of luminance caused by the deterioration can be corrected.

Abstract: The film magazine in the invention includes a pair of pinch rollers for pinching a film reeled out from a film roll container against a flat back tray of the magazine. Release means are provided to release the film from the pinch rollers at the time of mounting the film magazine onto the body of the camera. The pinch rollers are urged so as to pinch the film against the back tray after the film magazine is demounted from the body of the camera. This arrangement makes it possible to restrain the film in the film magazine until it is mounted to the body of the camera. Once the film magazine is mounted on the body of the camera, the restraining mechanism is automatically released to allow free movement of the film.
