Title: Picture reader, picture reading method and storage medium
Inventor: KASHIWAZAKI ATSUKO
IPC: H04N1/401
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To shorten scan time at previewing and at high speed scanning mode by variably setting displacement quantity per unit time and the number of sampling lines on shading correction data when light is modulated by a reading mode which is set. SOLUTION: Displacement quantity per unit time and the number of sampling lines on shading correction data are variably set when light is modulated by a reading mode which is set. In a device 16, a white reference plate is irradiated with adjusted light quantity and an image sensor 3 reads data so as to obtain the shading correction data. When the sampling of the shading correction data completes, an optical unit 10 is moved to an original reading start position in an auxiliary scanning direction and an original picture is read. When a designated reading mode is a previewing mode or a high speed scanning mode, the original picture is read/scanned while the optical unit 10 is moved at speed faster than in a regular mode.

Abstract: PROBLEM TO BE SOLVED: To provide a chip-type solid-state electrolytic capacitor of resin-mold structure which is free from positional deviation caused by directional deviation that occurs when a negative and a positive outer terminal are bent and possessed of the outer terminals which are easily bent, high in mechanical strength, and excellent in connection reliability, SOLUTION: A negative and a positive outer terminal, 15 and 13, are formed of metal band constant in width. The terminals 13 and 15 are led out of a molded resin body 16 at spots the nearest to a capacitor element 2, bent extending along the surface of the resin body 16, and set to make heir parts after their bends serve as connecting parts connected to the outside. As a distance between the bending spot and the connecting part of a terminal is short, the terminals deviate less in direction. When a terminal is bent upwards along the end face of the resin body 16, it grows wider in contact area with the outside, so that, it can be enhanced in connection reliability. Moreover, a cutout hole is provided to the terminal at a spot distant from a lead-out position in an extending direction, and a projection which is fitted in the cutout hole is provided to the resin body, whereby the terminal is corrected for directional deviation of bending and enhanced in positional accuracy.
