    摘要： A motor-driven type exposure adjusting device, such as a diaphragm-shutter device, adapted for a lens incorporating camera, an interchangeable lens, or the like. In the adjusting device, a rotary member has an optical path hole formed in a central portion thereof and is arranged to control the opening and closing actions of a plurality of light shielding blades. A stepping motor servers as a drive source for the rotation of the roatary member and is disposed outside of the optical path hole, and an aperture position detecting means detects a boundary between a given maximum aperture position defined by the light shielding blades and a stopped-down aperture position of the optical path hole. The aperture position of the optical path hole is detected through the rotating angle position of a rotary wheel to which the rotation output of the rotor shaft of the stepping motor is transmitted.

    摘要： A selective switching circuit which is operative to successively switch a plurality of other circuits, one at a time in a predetermined order, into an existing circuit configuration. An embodiment of the invention is described in relation to a magnetic strip card writing device, whereby information to be written on each of a plurality of strips is successively stored in corresponding registers, and later applied to the strips all at one time. Information in any of the registers may be preserved therein, with new information to be recorded being directed into the next ordered register.

    摘要： When a periodic pattern is not included in image data 210, a prediction error encoding unit 204 outputs the variable-length code of a prediction error quantization value 214 generated by prediction encoding as compressed data 215. When the periodic pattern is included in the image data 210, a periodic pattern encoding unit 208 outputs only information about the periodic pattern as the compressed data 215, while the output of the prediction error encoding unit is stopped. On the decompression side, while the copy instruction of a pixel value before one cycle from the compressed data is not detected, the decompression operation in a normal prediction encoding system is executed. When the instruction is detected, the pixel value one cycle before, internally stored is copied and outputted.
