Title: Original reader
Inventor: NAGATA YOSHIHIRO
IPC: H04N1/40
Filed: 1983-03-11
Abstract: PURPOSE:To prolong the service life of a light source and also to obtain stable luminous amounts by decreasing the extinguishing time to suppress the temperature drop of a filament and a tube in controlling the lighting of the light source and the scanning of an image pickup element in matching with the timing of subscanning. CONSTITUTION:When the next subscanning timing is inputted while a reading signal is outputted, the light source is lighted for a prescribed period t1 and then extinguished. Then, after the scanning period t2 and the lighting period t1 are both finished, the next scanning (period t3) is started. A signal of this scanning is an effective reading signal. If a subscanning timing does not come during a scanning period t5 when the effective reading signal is obtained, the light source is lighted when the scanning period t5 having the effective reading signal is obtained is elapsed and the scanning is finished. No restriction is given as to the scanning of an image pickup element 4 until the further subscanning. The scanning is started in the next subscanning timing. A signal in the scanning period t6 is an ineffective signal. The light source is extinguished for a prescribed period t4 (t4=t1) from the start of scanning. The next scanning is started after the end of scanning. A signal at this period t7 is stored between the scanning period t6 and the same period T2 and the light source is lighted for the period t4.

IPC: G06K13/06
Filed: 1994-03-11
Abstract: PURPOSE:To provide a paper feeding device which enables users to handle paper sheets in a comparatively light and easy manner even when the paper sheets are reliably held by a paper sheet feeding mechanism. CONSTITUTION:When a motor 81 is rotated counterclockwise, a two-stage gear 82 wherein a large drive gear 82a is geared with the drive source 81a of the motor 81 and a gear support body 84 are rotated clockwise. A planetary gear 83a for forward feed is geared with a drive pulley gear 85 to rotate the drive pulley gear 85 clockwise. This constitution respectively rotates each driven pulley 87, a timing belt 86, and each rubber roller 65a clockwise to feed a paper sheet in a direction. Meanwhile, when the paper sheet is pulled in a forward direction, rotary members arranged in a range extending from each rubber roller 65a to the drive pulley gear 85 are rotated counterclockwise. Since a planetary gear 83a for a forward feed is dissociated away from the drive pulley gear 85, a paper sheet is lightly handled.

In this case, the extracting operation of the on-state of one or two contacts in the block is allowed; and when the on- state of three or more contacts is extracted, a new contact on-state is not recognized until all contacts in the block are turned off temporarily. Thus, an accurate address is extracted even for the turn-on operation of plural contacts without using a by-pass diode.
