摘要： A lens moving device comprises a lens frame to which a lens is attached and a drive mechanism which moves the lens frame along the optical axis of the lens. An arm-receiving opening is formed in a connecting member provided on the lens frame. The drive mechanism has a motor, and an output shaft of the motor is connected to a feed screw, on which a nut is fitted. A moving member is integrally formed on the nut, and first and second arms are provided on the moving member. The first and second arms are inserted into the arm-receiving opening. The first and second arms are arranged in order along the line, in which the lens is moved. A spring force of the first arm is greater than that of the second arm.

摘要： A collision preventing mechanism for preventing a collision between a zoom lens system and a half-speed mirror in a variable scale factor copying apparatus for forming an electrostatic, latent image through the lens system onto a photo-sensitive drum by scanning an original document by a full-speed mirror and the half-speed mirror includes a device for moving the zoom lens system away from the half-speed mirror when an abnormal approach of the half-speed mirror causes the half-speed mirror to be moved into the vicinity of a zone which is occupied by the zoom lens system. This mechanism also includes a detector for detecting the abnormal approach of the half-speed mirror.

摘要： A lens moving device comprises a cam follower which is provided to a lens holding frame supporting a lens, and a cam gear with which the cam follower is engaged. The cam gear is rotated by a stepping motor, so that the lens holding frame and the lens move along the optical axis thereof. The cam gear is molded from synthetic resin and is provided with a stopper at the both ends of a non-operative area, in which the cam follower does not come in contact during a normal operation. The non-operative area has a gate mark, which is formed during the resin molding process. The stopper prevents the cam follower from interfering with the gate mark.

摘要： An optical variable power module has a movable lens unit slidably mounted on a chassis, such that the lens unit is moved along an optical axis defined thereby, and a movable mirror unit slidably mounted on the chassis, such that the mirror unit is moved along the optical axis of the lens unit. The movable mirror unit has a frame, a pair of supporting plates shiftably attached to the frame, and at least one mirror supported by the supporting plates. The chassis has a pair of abutment faces formed thereon such that the supporting plates can be abutted against the abutment faces. The abutment faces define a plane perpendicular to the optical axis of the lens unit, whereby the supporting plates are shifted with respect to the frame such that the longitudinal axis of the mirror supported by the supporting plates is perpendicular to the optical axis of the lens unit.

摘要： An optical module is intended to be assembled in an optical apparatus, and includes a chassis member having an opening therein. A mirror unit is provided in the opening of the chassis member, such that a lower part of the mirror unit protrudes from a lower surface of the chassis member, through the opening thereof. A protecting wall element, extending lower than the mirror unit, is formed along and suspended from at least a part of a periphery of the opening in order to physically protect the lower part of the mirror unit.

摘要： A laser shutter mechanism is provided and fitted to a window in an optical system container of, e.g., an optical scanning unit in a laser beam printer. The shutter comprises a screen member for preventing the laser beam from emitting through a window to a beam receiving unit. The screen member is movable between its operative and inoperative positions, while it is biased to its operative position wherein it closes the window. An operating member is provided on the beam receiving unit for moving the screen member to its inoperative position where the window is allowed to emit the laser beam therethrough. Only when said beam receiving unit is properly positioned against the window, does the operating member moves the screen member.
