Title: Camera
Inventor: HORIUCHI HIROYUKI
IPC: G03B11/04
Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To make obtainable a large overstroke without requiring high accuracy by closing a lens barrier by pulling and moving a 2nd driving member by means of a 1st driving member in the reverse direction by the displacement of a 1st engaging part to a 2nd engaging part when a lens barrel is moved from a photographing position to a non-photographing position. SOLUTION: The lens barrel 12 is extended together with an outer barrel 13 by the rotation of a motor. Therefore, the 1st driving member 24 is extended and a cam pin 24a moves to the front of a cam groove 14d. The end 24b of the notch 24d of the member 24 presses the lower part of the arm part 26a of the 2nd driving member 26, so that the member 26 is rotated counterclockwise. As a result, the lens barrier 21 is rotated counterclockwise centering a hole 21a, and two lens barriers 21 are separated from each other and get in an open state. When the lens barrier 21 is closed from the open state, the member 26 is pulled by a torsion spring 27 by the clockwise rotation of the member 24 and the lens barrier 21 is closed.

Title: Detecting method for focusing point
Inventor: MIYAZAKI IKUHITO
IPC: H01L21/027
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To detect a focusing point easily surely by disposing an original plate for projection in a conjugate position with an object in an observation optical system, while generating a moire fringe on the object surface by projected images themselves. SOLUTION: A first fringe pattern projecting luminous flux and a second fringe pattern projecting luminous flux are adapted to impinge on an objective lens 2 of an observation optical system. These pattern projection negatives 10, 20 are disposed in conjugate positions with an object in the observation optical system, while the original plates are set such that a moire fringe is generated by projection images themselves projected on the object surface. Thus, when focuses approximately coincide with each other, the moire fringe is generated first by two overlapping fringe patterns and further the moire fringe moves according to the adjustment of the focus. When the focuses coincide with each other completely, the moire fringe comes to a specified position.  Namely, the focusing point can be observed as the movement of the moire fringe, not as the presence/absence of the shear of a projected mark so that the focusing point can be easily surely detected.
