合であつた。``Prior Art'' Conventionally, a plate-shaped body on which information is recorded, such as a compact disk or a magnetic or magneto-optical disk, is stored in a case or tray that also serves as a holder and protects the disk, and is used to read out or reproduce the recorded information. Sometimes there is a method in which the disc is attached to a player and played by a reading head while rotating the disc. For example, in an optical CD player, a plate-like body 1 is placed on an erase or holder 3 as shown in FIG.
The fixed locking piece 5 and the locking piece 4 of the elastic hook part 2 lock the outer periphery of the plate-shaped body and hold it integrally on the holder, which is a simple structure. After the plate-shaped body is attached to the drive rotation shaft, the holder is pulled out manually by pulling the elastic hook with the fingertip to release the engagement with the plate-shaped body, or the holder is pulled out. Another method is known in which the plate-shaped body is pulled away from the locking piece and regenerated in a state where it can rotate freely, but since the elastic member of the locking piece is left tensioned, the elastic body This caused deterioration and damage to the equipment, which was extremely inconvenient.

はならなくなる。 However, if the external dimensions of the regenerator, especially the height, can be minimized so that only a narrow opening in the front can be provided, there is no space to hook a finger onto the elastic hook, so some other method must be taken. It becomes indispensable.

のである。``Problems to be Solved by the Invention'' Therefore, in order to solve the above-mentioned difficulties, the present invention aims to fix the locking piece of the elastic hook part of the holder that locks and holds the plate-like object to the regenerator. This paper proposes a mechanism that uses a small space inside the housing to automatically release the locking and holding state electromechanically by turning on a switch when the holding body is loaded into the housing. .

図で再生機内での配置関係を表わす。``Structure of the invention'' In FIG. 1, a plate-shaped body 1 is placed on a holder 3 as shown by the imaginary dotted line, and its outer periphery is secured by a locking piece 5 and a locking piece 4 of an elastic hook part 2. In the locked and held state, the rotating body 7 is provided with a gear 13 for power transmission on the periphery coaxially with the central shaft 6 on the lower side of the holder, and at least one through rod 8 on a concentric circle.
The central shaft is rotatably inserted into the bearing 9, and the lower end of the penetrating rod is slidable on the top surface 11 of the annular wall 10, the height of which rises at the periphery changes continuously. This is an exploded perspective view illustrating the arrangement in which the penetrating rod is assembled on the stand 12 and the upper end peripheral edge of the penetrating rod abuts the end surface of the locking piece 4 of the elastic hook portion of the holder, showing the arrangement within the reproducing machine.

表わしている。``Operation'' The configuration and arrangement described above are such that transmission force is applied from the power source to the gear 13 carved on the periphery of the rotating body 7, and the penetrating rod 8 is moved along the top surface of the annular wall of the base to the position shown in the figure. The upper end of the penetrating rod moves in the direction of the central axis and in the direction of the plate surface of the rotating body, and the upper end of the through rod is connected to the handle 1 of the holder.
This pattern shows that the elastic hook portion provided on the 4th side comes into contact with the upright side portion 41 of the locking piece 4 and attempts to move further toward the handle side against the elasticity of the elastic hook portion.

何等の拘束を受けない自由状態に保たれる。 FIG. 2A is a top and side view of the device of the present invention at the starting point, and FIG. 2B is a top and side view of the device at its final stage. As the penetrating rod rotates, the direction followed by the upper end of the penetrating rod moves in both the vertical and horizontal directions as shown by the arrow, and comes into contact with the upright side portion 41 of the locking piece 4 of the elastic hook portion, and is further influenced by its elasticity. By pushing against the arrow in the direction of the arrow, the locking piece that is locally engaged with the periphery of the plate is separated, the engagement is released, and the center hole of the plate is released. It is clamped onto a spindle and driven to rotate, making preparations just before reading out recorded information begins. That is, the rotating body further rotates clockwise (as indicated by the arrow) from the state shown in FIG. 2B,
When it returns to its original position, the elastic hook remains free and free from any restraints.

きい。``Effect'' Thus, according to the present invention, the simple principle that the locus of movement of the penetrating rod provided at an eccentric position moves in both the vertical and horizontal directions with one rotation of the rotating disk is utilized, Because of the structure that allows the elastic locking piece to be easily released from the lock, it is possible to easily operate a device that is linked to the engagement of a switch to operate the means for applying rotational driving force to the rotating body, even in a narrow space. In addition, the practical advantages of not causing fatigue, deterioration, or damage to the elastic hook part are very large.
