Description

  The present invention relates to a front panel mounting position adjusting mechanism of an electronic apparatus equipped with a disk drive device such as a CD or a DVD.

  2. Description of the Related Art Conventionally, in an electronic apparatus equipped with a disk drive device such as a CD or DVD, the disk drive device is fixed to a main body chassis of the electronic device, and an opening of a front panel through which the disk tray of the disk drive device enters and exits; In many cases, the disk tray panel is moved and adjusted in order to make the gap formed between the disk tray panel and the periphery of the disk tray panel uniform.

4 and 5, the disk drive device 54 is fixed to the base 7 via a frame 8 a attached on the bottom chassis 60 inside the electronic device main body. The front panel 51 is first screwed to the sub chassis 59, and the sub chassis 59 is screwed to the side frames 5 standing on both sides of the main body.
A gap between the opening 51a of the front panel 51 and the peripheral surface of the disc tray panel 52 caused by each processing error is a screw hole for fixing to the disc tray 53 of the bracket 57 attached to the back of the disc tray panel 52. And tighten the mounting screw 56 after adjusting the vertical and horizontal positions of the disc tray panel 52 so that the gap between the front panel 51 and the disc tray panel 52 is uniform while tightening the mounting screw 56 with a screwdriver or the like. Yes.

  For this reason, after adjusting the vertical and horizontal positions using the disk tray panel jig 61 in which the driver adjusting hole 61a is drilled in the mounting screw hole position in advance, the lower mounting screw 58 is loosened to loosen the disk tray panel jig. After the 61 was removed, the disc tray panel 52 was replaced with a regular one, and the front and rear positions of the disc tray panel 52 were adjusted before the lower mounting screw 58 was tightened.

Further, in the technical document 1, a substantially flat tray having a disk mounting portion formed in a circular shape at a substantially central portion and a rail for holding the tray so as to be movable back and forth are disposed on the inner surface, and the tray is accommodated. In a disk device having a housing and a panel that serves as a front lid when the tray is housed in the housing, the panel is provided with a contact claw that contacts the housing when the tray is housed in the housing. The position of the panel is determined by the contact portion of the panel contacting the housing. Thereby, since a panel is directly positioned with respect to a housing, the dispersion | variation in the clearance gap between an electronic device and a panel can be reduced.
