IPC: A44B11/24
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a band clasp which is excellent in safety and can prevent the clasp main body from floating off the watchband when used. SOLUTION: A push-pin 3 is attached in the middle of an attaching shaft 2 attached to one end 1a of the band 1, and a frame-shaped clasp main body 11 is attached to both ends of the push-pin 3. A socket part 5 for the push-pin 3 is attached to one end of the clasp main body 11, and a presser part 13 to press the surface of the other end 1b of the band 1 is attached to the other end of the clasp main body 11. A presser ring 12 is mounted on the presser part 13, with an engaging protrusion 14 to be engaged with the presser ring 12. Therefore, as the other end 1b of the band 1 and the one end 1a are connected with the other end 1b inserted into the clasp main body 11 engaged with the push-pin 3, and are inserted into the presser ring 12 with the other end 1b laid on top of the one end 1a, the presser part 13 is prevented from floating off the watchband 1 even when the band 1 is curved, and the presser ring 12 will not be detached from the presser part 13 by the engaging protrusion 14 accidentally, so the clasp to be provided can be highly safe.

Abstract: PROBLEM TO BE SOLVED: To detect and correct a position of a board surface, etc., highly accurately and rapidly by selecting a first detection mode wherein measurement is executed during movement of a board or a second detection mode wherein measurement is executed after a specified detection surface is almost positioned in an image space. SOLUTION: In a method which lays stress on speed, step movement is started (S401). Whether or not a board attained a measurement position during movement before an aimed position is judged while an existing position is always read (S402). When it is judged that the board attained there, focus is measured (S403). In a method which lays stress on correction accuracy, step movement is started (S501). Whether or not a board attained a measurement position during movement before an aimed position is judged while an existing position is always read (S502). When it is judged that the board attained there, judgment is repeated successively until the board attains an area near a designated aimed position (S503). When it is recognized that the board attains the area, focus is measured (S504). Two detection modes are used properly in this way and a position, inclination, etc., of a board surface are detected and corrected highly accurately and rapidly.
