Abstract: An image signal output device for use in a passive range finder. The device can correct the sensitivities of sensor arrays according to the amount of incident light. The output device has line sensor portions that produce pixel outputs. An A/D converter portion A/D converts these pixel outputs. At this time, the A/D conversion range of the A/D converter portion is modified according to the difference in sensitivity between the line sensor portions.

Abstract: A font pattern to be stored is created by sequentially forming exclusive logical sums neighboring first bit patterns A1-A20 to form a plurality of second neighboring bit patterns B1-B20; designating at least one or more than one bit pattern which appears most frequently in the plurality of second bit patterns as a reference bit pattern, comprising and storing the difference of each bit pattern of the plurality of second bit patterns and the reference bit pattern per each bit pattern, and storing only the bit patterns which differ from the reference bit pattern in the plurality of second bit patterns.

Abstract: A printer includes a printer body and a setting device provided with a plurality of switches which are operable for setting various operating functions of the printer. An interconnection on the printer and the setting device is operable to mechanically and electrically interconnect the setting device to the printer and to provide for mechanically and electrically disconnecting the setting device from the printer.
