摘要： A relative adjustment between an optical disc rotating mechanism and an optical pickup is adjusted by rotating a rotary member against a biasing force of an engaging projection. As the rotary member is rotated, the projection is slid for movement on an inclined surface, changing a relative position between the rotary member and a bottom wall of a subsidiary chassis, causing the subsidiary chassis to have a varied inclination relative to a main chassis. An adjusted condition is maintained by an engaging force between an engaging groove and the engaging projection biased toward the rotary member.

摘要： A distance measuring device for an automatic focusing camera includes a light receiving lens and a multilayer printed circuit board mounted on a holder. A potting frame is provided on the lens-facing side surface of the printed circuit board. An optical sensor and an IC are both mounted within a space enclosed by the potting frame and simultaneously sealed by a protecting resin. Resistors and capacitors of a distance measuring circuit are mounted on the opposite surface of the printed circuit board. The two surfaces of the printed circuit board are connected to each other via a through hole to construct the distance measuring circuit. The protecting resin transmits light having specified wavelengths. The light reflected from a subject to be photographed is received by the optical sensor after passing through the protecting resin, and the distance to the subject is calculated on the basis of the received light data.

摘要： An optical pickup position control method that uses a stepping motor to control the position of the optical pickup, and that makes it possible to reduce the out-of-step noise generated from the motor and to accurately position the optical pickup, has a first procedure that gives the motor a control command to move the optical pickup in the direction toward the maximum feed position by a feed amount that is smaller than the maximum feed amount from base position to the motor's maximum feed position; a second procedure that gives the motor a control command to move the optical pickup in the direction toward base position by the maximum feed amount; and a third procedure that gives the motor a control command to move the optical pickup in the direction toward maximum feed position by the center position feed amount from base position to center position.

摘要： A light-receiving apparatus comprises a light-receiving device positioned relative to an external component with increased accuracy. A sealing frame is mounted on a printed circuit board. One corner of this sealing frame is detectable by image processing. The position inside of the sealing frame at which the light-receiving device should be mounted is determined from the detected position of the corner of the sealing frame. A sealing material is injected inside the sealing frame and cured, thereby sealing the light-receiving device. Pins of the external components are inserted into holes or cutouts in the sealing frame and made stationary when the light-receiving device is mounted to the external component. The mounting of the light-receiving device inside the sealing frame is based on the sealing frame, and the mounting of the apparatus to the external part is based on the sealing frame. Therefore, the light-receiving device can be mounted relative to the external part with high accuracy.

摘要： A drive device has a feed mechanism that causes a control object to move in order to control the positioning of the control object, a motor that serves as the drive source of said feed mechanism, and a control means that controls this motor. The control means has an operation history memory unit that stores the operation history of whether the motor is doing an initial start or a restart, and a command selection unit that selects control commands and outputs them to said motor based on information stored in said operation history memory unit. Because intermittent operation that repeatedly drives and stops the motor occurs when there is a restart, the thermal shutdown associated with overheating of the driver IC is avoided, and any difference between the feed amount due to the control means and the actual feed amount can be prevented.
