Inventor: SUZUKI NORIYUKI
IPC: G01B11/00
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a recognition method in which the three-dimensional position of a sheetlike object can be recognized at low costs and with high accuracy by a method wherein two holes existing in the sheetlike object and two straight lines existing on two side faces are photographed as well as positions of the holes and the straight lines are detected respectively on the basis of photographed images. SOLUTION: A hole 6 existing inside a recognition range 7 on the surface of a sheetlike object 1, a hole 8 existing inside a recognition range 9 on the surface of the object 1, a straight line 10 existing inside a recognition range 11 on the side face of the object 1 and a straight line 12 existing inside a recognition range 13 on the side face of the object 1 are photographed by using TV cameras or the like.

Title: Locking mechanism for cover and information equipment having the same
Inventor: TAN CHEN KYATTO
IPC: E05C21/00
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To easily lock and release a cover. SOLUTION: When a device main body is rotated to a belt, a hook part 29 of a cam lever 26 is locked with or released from a stopper 15, a cover 14 is set in a state which is closely held or a state which can be opened. That is, since a lock mechanism of the cover 14 is set in a releasing state only by rotating the device main body from a vertical direction to horizontal direction, a conventional operation used after an opening/closing key of the cover 14 is eliminated, and usability is improved. Therefore, since the lock mechanism is locked and released only by rotating an entire cabinet as an operating body, it is possible to facilitate lock and release operations, opening and closing motion of the cover 14, and exchange operation of a cassette. Moreover, since a protruding amount of the device main body from a waist part decreases as compared with a case carried with an entire device in a state of a horizontal direction, the device main body when carrying does not become obstructive.
