IPC: G06T7/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To check a printed matter even when its positioning is rough or the form is elastic when the printed matter image is compared with a sample image to detect the stains, the breakage, the wrong characters, etc., of the printed matter. SOLUTION: A check sample and the image of a printed matter to be checked are read via an image input part. Then a positioning pattern is selected at two points based on those read sample and image to calculate the position coordinates, and the address conversion is performed so as to put both images on each other (S1, S2). The edge components of both images are extracted, binarized and divided into blocks (S3 to S5). Then a position where both images put on each other with highest accuracy is decided by shifting the pixels one by one in every block, and the information on both images are compared with each other at the decided position to detects the different points between them (S6, S7).

Title: Optical memory card
Inventor: NAKAHARA TAKASHI
IPC: G11B23/00
Filed: 1986-04-26
Abstract: PURPOSE:To easily discriminate the setting state of a card in loading the card to a device by providing a light transmission part to part of the optical memory card and detecting a light beam transmitted through the light transmission part. CONSTITUTION:A hole 3 is provided to the optical memory card 1 to detect the loading state and the hole 3 is biased to one side from the mid-position of the card 1 with respect to the short side direction of the card 1. When the card 1 is loaded normally in the device, the light flux from a projection side LED 4 is received by a light receiving side LED 5 via the hole 3. Even when the card 1 is loaded by the correct direction, if the card is loaded with wrong side, since no hole 3 comes in the optical parth from the LED 4 to the LED 5, the LED 5 does not receive the light through the hole 3. Thus, the state of the front/rear side of the card 1 is discriminated by having only to check the electric signal from the LED 5.

Abstract: PURPOSE:To improve the precision of scanning light and picture quality with simple constitution by providing partial noncontacting part between a fitting seat and a polygon mirror, and a rigid late body and an adjusting adapter and making those members of only rigid materials. CONSTITUTION:The polygon mirror 10 fitted slantingly to a rotating shaft 11 is adjusted by turning up an adjusting screw 15 so that respective mirror surfaces 10a are perpendicular to the rotating shaft 11. Then, the rigid plate body 13 is used to disperse the one-point concentrated load by the depression of the adjusting screw 15 into a distributed load which presses a surface, thereby reducing the local application of an unreasonable force to the polygon mirror 10. A spacer 14 prevents the gap between the plate body 13 and adjusting adapt er 16 from narrowing down extremely and is reduced in diameter so that there is no hindrance to the adjustment by the adjusting screw 15. This constitution uses no elastic member and use only rigid plate bodies entirely, so there is no variation in heat rotating force and other disturbance.
