再生を行う様にしたものがある。B. Prior Art Recently, devices called optical disk players, which use optical pickup to read out signals from a disk on which signals have been recorded, have become popular.
As shown in Japanese Utility Model Application No. 59-71471, the disk player has an optical pick-up mounted on a support member that slides on two mutually parallel guide rails consisting of a shaft disposed on a chassis. ,
There is a device in which the optical pickup is moved in the radial direction of the disk by driving the support member to perform disk playback.

デイスクプレーヤの輸送時には、前記光ピツクア
ツプを輸送時の衝撃から保護する必要がある。 By the way, in order to reproduce a disc using the optical pickup, it is necessary to correctly project the light beam generated from the optical pickup onto the signal on the disc. Correspondingly, the optical pickup is precisely constructed so as to be driven vertically and horizontally along the track of the disk. Therefore, when transporting an optical disc player, it is necessary to protect the optical pickup from shock during transport.

を駆動する為の駆動機構に悪影響を及ぼさない。 In order to protect the optical pickup from impact during transportation, conventionally, fixing parts such as screws and pins are used to secure the support member on which the optical pickup is placed to the guide rail on which the support member is abutted. The optical pickup was pressed against the upper surface of the optical pickup to increase the contact force and fixed to the chassis, and the movement of the optical pickup was restricted, thereby alleviating the shock during transportation. By doing so, the support member does not slide, so that not only the optical pickup but also the drive mechanism for driving the support member are not adversely affected.

Problems to be solved by the invention In the above method, in order to press the support member against the upper surface of the guide rail when fixing the support member to the chassis, the guide rail is not made of an elastic material such as a synthetic resin material. , the upper surface of the guide rail may be deformed, and in order to finely adjust the height of the optical pickup and adjust the optical axis, the support member is provided with an adjustment member at the part that contacts the guide rail. However, there have been cases where the adjustment member has shifted. Furthermore, since the above-mentioned method uses fixing parts such as screws and pins that are removed from the main body when using the disc player, it is easy to lose the fixing parts, and it is difficult to insert the fixing parts. It was difficult to align the holes, which was inconvenient when retransportation was required.

is in the unlocked position shown by the solid line in FIG. 1, and the sliding part 8 of the support member 5 is placed on the upper surface of the second guide rail 3 as shown in FIG.
b so that it does not come into contact with the second guide rail 3. Therefore, when a disk is played or searched and a motor (not shown) is rotated, the rotation of the motor is transmitted to the pinion 10 via a transmission mechanism (not shown), and the rotation of the pinion 10 is is a rack 11 provided on the side surface of the sliding portion 7 of the support member 5.
Therefore, the support member 5 is slid in the direction of arrow A or arrow B in accordance with the rotation of the pinion 10.

つても支持部材５の摺動は規制される。 On the other hand, during transportation, the support member 5 is first slid to the position closest to the turntable 12 on which the disk is placed, and then the lock member 9 is rotated in the direction of arrow C. When the lock member 9 is rotated, the tapered tip 9b of the lock member 9 is inserted between the sliding portion 8 of the support member 5 and the chassis 4, and the lock member 9 rotates in the direction of arrow C. Along with the movement, the thicker portion of the tip portion 9b is gradually inserted between the sliding portion 8 and the chassis 4. Here, the support member 5 is rotatably supported around the first guide rail 2, and the thickest portion of the tip portion 9b is longer than the distance between the sliding portion 8 and the chassis 4. Since it is thick, the contact force of the tip portion 9b to the sliding portion 8 causes
The support member 5 is pushed upward about the first guide rail 2. When the support member 5 is pushed up by a predetermined amount, the claw 8a of the locking piece 8b comes into contact with the protrusion 3a of the second guide rail 3, as shown in FIG. Rotate. In that state, the support member 5
is fixed by the contact force between the claw 8a of the locking piece 8b and the protrusion 3a of the second guide rail 3, and the locking member 9 is in the locked position shown by the dashed line in FIG. Also, at this time, as shown in the figure, the main body part 9c and the tip part 9b of the locking member 9
Since the protrusion 8c of the sliding part 8 is gripped by the
Even if the contact force between the claw 8a and the protrusion 3a weakens, the sliding movement of the support member 5 is restricted.

外されないので、再輸送時に便利である。Effects of the invention As described above, according to the invention, the support member on which the optical pick-up is placed is fixed during transportation, so that the optical pickup and support member are protected from impact during transportation. It is possible to protect the drive mechanism for Further, the tapered portion formed at the tip of the locking member is displaced upward by the contact force against the support member to bring the locking piece into contact with the guide rail, and the contact force causes the support member to come into contact with the guide rail. Since the disc player is fixed, deformation of the upper surface of the guide rail that comes into contact with the support member and displacement of the optical pickup adjustment member do not occur when the disc player is used. Furthermore, since the parts for fixing the support member are not removed from the main body during use, it is convenient for retransportation.
