[Embodiment] As shown in Fig. 1, a disc 1 records information on a recording medium or reproduces information on the recording medium. The optical disc 1 has a casing 3 and a dish tray 5 which are arranged to be stored in or discharged from the casing to feed the optical disk into the casing 3 or to be taken out from the casing and sent to the outside. When the push button switch 9 (5) 1261815 formed on the front panel 7 on the surface of the outer casing 3 is pressed, the disc tray 5 is instructed to feed the optical disc into the outer casing by a loading mechanism (not shown) formed in the outer casing 3. 3, or taken out from the outer casing and sent to the outside. FIG. 2 is an exploded view showing the main components of the optical disc drive of FIG. 1. As shown in FIG. 2, the optical disc drive 1 has a housing 1 occupying most of the space of the outer casing 3. 1, and the housing 1 1 holds various components and structures. A picking frame 13 is disposed at a specific position of the pick-up mount 15 in the housing 11. The pick-up rack 13 has a motor for holding the optical disc, and when information is read from the optical disc or information is written to the optical disc, the The motor rotates the disc at a specific speed. As shown in Fig. 3, the mounting seat 15 has a pivot pin 15a which, when inserted into a rotating pivot 1 1 a at a specific position of the outer casing, the pivot pin 15 a can directly oppose the integral mounting seat 15 The outer casing 3 is rotated (tilted) by a specific angle (in the case where the pickup frame 13 is mounted). Therefore, when the push button switch 9 issues an instruction to load/send the optical disc, the mount 15 (and the pick-up rack 1 3 fixed to the mount 15) pivots (tilts) along the pivot pin 15 a, and retreats to A specific retreat space in which the disc is placed on the disc tray, the motor and the pickup frame are not in contact with the disc tray 5 and the optical disc. As shown in Figure 4, the pivot pin 15 a presents a split pin structure that is integrally formed with the mount 15 at a particular location of the mount 15 and has a projection that splits into at least two portions (two positions). From 1 5 b, and a slit 1 5 c to make the protrusion elastically deformable. Due to the elastic nature of the material used in the mount 15, the resulting projections are temporarily displaced (elastically deformed) to the split side.

As will be disclosed in Figures 5-7, the force is formed such that at least a portion of the contact is corresponding to the inner wall of the opening. 5-7 illustrate the relationship between the pivot pin 15a of the mount 15 and the pivot pivot 1 1 a of the housing 3 (Fig. 3). In order to simplify the explanation, only the opening (hole) of the rotation pivot 1 1 a of the housing 3 is shown. As shown in FIG. 5, at least the pivot pin 15a on both sides of the contact opening 1 1 a is formed such that the rotation pivot (opening) 1 1 a is a square shape close to a square, and is formed substantially parallel to the sides of the opening 1 a. The slit 1 5 c is obtained by dividing the projection 1 5 b of the pivot pin 15 a.
