Abstract: A lock switch apparatus comprises: a key insertion hole 7; a detection switch unit 9 for detecting the insertion of an operation key 2 in the key insertion unit 7; a lock unit 11 for locking the operation key 2 when the operation key 2 is inserted in the key insertion hole 7; and a lock detection unit 13 for detecting the operation state of the lock unit 11. The lock unit 11 is configured so that the operation key 2 is locked by the attraction of a solenoid 12, a movable system of a solenoid-side movable portion is configured by providing an associatively movable portion which moves in association with the solenoid-side movable portion with respect to the solenoid-side movable portion of the solenoid 12, and vibration/impact absorbing means 14 is provided to provide a balance state of operating forces applied to the movable system.

Abstract: There is provided an optical card processing apparatus comprising: a card holder which is supported to a guiding mechanism so as to be reciprocated and is formed with an optical card holding portion on a lower surface; a card loading/ejecting mechanism, arranged at a card inserting port, for detecting an optical card and for attaching and detaching the optical card to and from the optical card holding portion of the card holder. A card inclination correcting mechanism is arranged for the card holder, for making a track line direction of the optical card coincide with a moving direction of the card holder. A card transfer mechanism in which a pair of pulleys are arranged along a moving path of the card holder, an endless belt is wound between the pair of pulleys, a proper portion of the belt is coupled with the card holder, and one of the pulleys is coupled with a drive motor which rotates in a single direction.

Abstract: The present invention relates to an optical card reader that detects any relative inclination of the card by measuring the relative motion of the optical tracks themselves. The optical card reader comprises a card holding portion, an optical head having the ability follow data tracks on the optical card, and a detector that measures the angle of inclination of the optical card from a tracking signal generated from a one-dimensional relative movement of the card holder and the optical card.

Abstract: An optical card processing apparatus includes a holder feed mechanism (4) for reciprocating a card holder (2) holding an optical card (8), an optical head (5) for recording information on and/or reproducing information from the optical card held by the card holder, and a card holding mechanism provided on the card holder for pressingly holding at least three sides of the optical card. Deformation of the optical card can be corrected and vibration thereof suppressed by the card holding mechanism. As a result, focal-point error due to card curvature and vibration is reduced and optical cards can be fed at a higher speed.

Abstract: An apparatus for locking a movable stage onto a stationary base, the stage being moved in the state floating above the base. The apparatus comprises a cap-like vacuum suction plate fixedly combined with the stage and defining a space in cooperation with the stationary base, wherein the space is selectively connected either to an air supply source or to a vacuum source. To move the stage in the floating stage, the space defined below the vacuum suction plate is connected to the air supply source to thereby form an air bearing between the vacuum suction plate and the base plate, whereby a gap and parallelism is maintained therebetween. Upon completion of positioning of the stage, the space is connected to the vacuum source so that the vacuum suction plate is locked onto the stationary base under the suction effect brought about by evacuation of the space.
