構成したものである。 In this prior invention, a locking member is disposed at the bottom of the chassis along the movement locus of the optical head, and the locking member is reciprocated between an engagement position and a non-engagement position with respect to an engaging element provided at the bottom of the optical head. A spring for moving the lock member to the engagement position and an electromagnetic device for moving the lock member to the non-engagement position are provided at the lower part of the chassis, and by cutting off power to the electromagnetic device, the lock member can be moved into the spring state. Accordingly, the optical head is moved to the engagement position and engaged with the engaging element, thereby locking the optical head at an arbitrary position on the movement locus.

ある等、実際上大変であつた。 In other words, it is extremely troublesome to supply power to each assembly at this stage, so in an actual assembly line, a worker must open the chassis from the opening for moving the optical head provided on the top surface of the chassis. The optical head is moved by inserting the hand underneath and using the fingertips to move the locking member against the spring to the disengaged position, but this work requires inserting the hand into a narrow space. This was difficult in practice, as it was very dangerous and could easily injure hands and fingers.

ンク23によつて連結されている。 Next, as shown in FIGS. 3A and 3B, an engaging element 12, which is a vertical pin, is fixed to the lower part of one end of the optical head 2. As shown in FIGS. And Figures 1 and 2
As shown in the figure, a long locking member 13 is arranged along the movement locus of the engaging element 12. This locking member 13 is made of sheet metal, for example, and is provided with a sawtooth-shaped engaging portion 14 over the entire range of movement of the engaging element 12. As shown in FIGS. 1 and 1, both ends of the lock member 13 in the longitudinal direction are rotatably supported on a pair of support plates 15 fixed to the lower surface of the chassis 1 via a pair of fulcrum shafts 16. The locking member 13 is in an engagement position in which the engaging portion 15 engages with the engager 12 as shown by a solid line in FIG. 2 and in FIG. 3A, and in an engagement position shown by a dashed line in FIG. As shown in the figure, it is configured to be able to freely reciprocate in the directions of arrows c and d between the disengaged position and the non-engaged position. An arm 17 is integrally provided at one end of the locking member 13, and a spring 20 is engaged between the arm 17 and a pair of spring engaging portions 18 and 19 provided at the bottom of the chassis 1. As shown in FIG. 3A, it is rotated in the direction of arrow c and urged to move to the engagement position. Then, the electromagnetic device 21 for moving the locking member 13 to the non-engaging position is activated by the spring 2.
The suction rod 22 and the arm 17 are connected by a link 23.

ロツクすることが出来る。 Next, for example, when the player is turned off or the AC
When the power is turned off, the power to the electromagnetic device 21 is cut off, so that the locking member 13 is rotated by the spring 20 in the direction of arrow c and moved to the engagement position, as shown in FIG. 3A. The sawtooth-shaped engaging portion 14 is engaged with the engaging member 12, and the optical head 2 is automatically locked. At this time, since the engaging portion 14 can engage the engaging element 12 at any position, the optical head 2 can be locked at any position on the movement trajectory.

体に折曲げられている。 Therefore, in the optical disc player of the present invention, a release lever 26 is attached to the upper part of the chassis 1, as shown in FIGS. 1 and 2. This release lever 26 is rotatably supported on a fulcrum shaft 27 mounted on the chassis 1 in the directions of arrows f and g in FIG. A spring 30 locked between a pair of spring locking portions 28 and 29 rotates in the direction of arrow f in FIG. A protruding piece 26a integrally bent downward from the tip of the release lever 26 is vertically inserted below the chassis 1 through a small opening 31 provided in the chassis 1, as shown in FIGS. 3A and 3B. The projecting piece 26a is inserted into a notch 32 provided at the upper end of the arm 17. In addition, release lever 2
6 has a protruding piece 26b bent upward so that it is easy to put a finger on it.
