Abstract

PURPOSE:To attain the reciprocating motions of optical cards at high speed and with low power consumption by providing a repulsing means at the termination of a linear movable range for the card tray of a guide means which holds cards and gives the linear reciprocating motions to these cards in the prescribed direction. CONSTITUTION:A movable part 13 where an optical card 1 and a card tray 2 are provided integrally is supported by a guide 3 which guides the part 13 is the reading direction of the card 1. An information read/write pickup 11 for optical cards 1 is set on the surface of the part 13 at the side opposite to the surface where a linear actuator 14 is set. The actuator 14 performs the control so that the tray 2 moves at a comparatively equal speed while the pickup 11 is giving a recording or reading action to the card 11. The tray 2 moves the card 1 from an end through the other end toward the pickup 11 at an approximately equal speed and inverts the moving direction of the card 1. For this purpose, the moving energy of the part 3 is once stored in the form of the strain energy of a spring and then released.

Normally, when recording information on an optical card-shaped recording medium (hereinafter referred to as an optical card), it is recorded as a spiral or circular pit on a disk-shaped optical recording medium, which is widely used in practical applications. Unlike the case, they are recorded on the reflective surface of an optical card as a group of fine holes arranged in a straight line parallel to the edge of the optical card and parallel to each other.

In order to record information in this way, or to read information recorded in this state, a laser beam focused on the reflective surface of an optical card is directed relative to the information hole row. have to be moved. In the case of optical disks that record in a spiral or concentric pattern, a laser beam traces the bits as the disk rotates, but in the case of an optical card, the laser beam traces the information by the reciprocating movement of the optical card. A method of tracing the rows of holes is being considered. Information is recorded on an optical card in a two-dimensional plane as a group of parallel straight lines, but in addition to the reciprocating movement of the optical card mentioned above, an optical pickup that reads information by reflection of laser light is also used to reciprocate the optical card. This is a method that allows information at any position on the optical card to be read by moving in a straight line in the direction of direct firing and parallel to the optical card. In this system, the reciprocating speed of the optical card is an important technical issue that determines the data input/output speed of the entire system. The capacity of optical cards currently being considered is 2 to 4 M hyt.
It has a large capacity of 1.5 t, and the information density handled by the system is also extremely high. Therefore, data must be written or read at a sufficiently practical speed (for example, about 3.75 Hz).

Since the reciprocating motion of the optical card must be performed at a relatively constant speed during writing and reading, the acceleration and deceleration of the reciprocating motion is concentrated at both ends of the transport device. Therefore, the drive mechanism requires a large driving force.

When repeating reverse rotation, a large drive current is required for the drive motor 8, and the speed of reciprocating movement of the card tray 2 cannot be increased sufficiently.

Therefore, in order to reverse the direction of movement of the card tray 2, the movement of the movable part 13 is made to be received by repulsion springs 4 with small internal damping disposed at both ends of the guide 3, which is a movable part guiding means. The kinetic energy is temporarily stored as strain energy in the spring, and then the strain energy in the spring is released as kinetic energy in the opposite direction of the second instantaneously movable part 13. During this process, the guide 3
By adopting a mechanism in which the movement is performed at both ends, the load 4 on the second actuator 14 is only caused by the friction between the movable part 13 and the guide 3. In other words, since the strain energy of the spring is used to reverse the direction of motion of the movable part 13, no load is applied to the linear actuator 14.
