Title: Double feed detecting device for paper form
Inventor: NOGAMI YUTAKA
IPC: B65H5/36
Filed: 1989-12-19
Abstract: PURPOSE:To correctly detect double feed state even for a paper form on which curl is generated, by projecting a lower guide plate in a paper form transport passage which faces to a swing member for detecting the paper form thickness toward a swing member, not toward the front and rear parts. CONSTITUTION:Though a paper form P which passes through a paper form transport part 9 shifts along the upper surface of a lower guide plate 10, the paper form passes slidingly along a projection part 11 installed on a guide plate 10, even if curl is not generated on the paper form. In a part where the paper form thickness is detected by a swing arm 3, the undersurface of the paper form passes in contact with the projection part, in both cases where curl exists and does not exist on the paper form P. Accordingly, in a part where the top edge part of the arm 3 presses the paper form P, the curled part does not push up the arm 3, and the thickness of the paper form P can be detected, correctly. Accordingly, even if the arm 3 does not press the paper form P with a strong force in the thickness detection part, the curled part does not push up the arm 3, and the generation of any trouble that the arm 3 is excessively swung is prevented.

Title: Image pickup device
Inventor: WATANABE TAKESHI
IPC: H04N5/378
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain an image having no unnaturalness over a wide exposure range by providing a means which varies the exposure time range of a solid- state image pickup element to an integral multiple of a vertical synchronizing signal range, and evaluating an exposure quantity and controlling the gain of an amplifier and the exposure time range. SOLUTION: A video signal obtained by an inter-line transfer type CCD 1 is amplified by an AGC amplifier 2 and converted into a digital signal by an A/D converter 3. Then TG/SSG 4 generates a CCD drive signal and various synchronizing signals. A DSP 5 converts a digital video signal into a luminance signal and a color difference signal. An MPU 6 finds the mean value of the luminance signal in one frame to evaluate exposure, performs exposure time control (electronic shutter control) over the CCD 1, and further controls the gain of the AGC amplifier 2. The MPU 6 extends an exposure time fully to one frame when a subject is dark, widens the control range of the exposure time to an integral multiple of a normal range when noise becomes conspicuous as the gain of the AGC amplifier 2 is increased, and continues to send an image of the same frame out during the period.

IPC: G03G15/08
Filed: 1990-11-30
Abstract: PURPOSE:To improve a carrying property with possibility, remaining developers in a bottom part of a casing due to insufficient carrying, eliminated by fitting the shape of a carrying auger to a tapered surface of the casing to make a tapered state. CONSTITUTION:A casing 1 is manufactured by the injection molding of synthetic resin, and has a tapered state expanded to a cover body 1a. Also a carrying auger 3 is made a tapered state in which its tip part is slightly narrow and it is expanded to a base part. Setting a supply device filled with developers causes the engaging of a drive mechanism and an engaging piece 3b to rotate the auger 3. This rotation turns a stirring rotations member 2 via a gear 3a and a driven gear 2c. This rotation of the member 2 stirs the developers, and a part of them is carried in a supply port 4 direction via the auger 3. Consequently the developers are gradually reduced, however are totally discharged from the supply port 4 without remaining in a bottom part because the outer peripheral edge of the auger 3 is parallel to the bottom surface of a housing part 6.
