Abstract:
1. A disk player comprising: a casing for supporting a tray so as to cause the same to advance and retreat; a drive chassis having a spindle motor with a turntable and an optical pickup mounted thereon; a pair of left and right pressing pieces that are provided so as to protrude from the front part of the casing integrally therewith, for pressing down the front part of the upward moving drive, wherein: a pair of left and right pivotal supporting axes protruding from the base end portion of the drive chassis are inserted into bearings secured at the rear side of the casing and is fitted into a cam hole of a cam plate on which a cam shaft protruding from the tip end portion of the drive chassis is slidably disposed in the left and right direction orthogonal to the forward and rearward direction at the front portion of the casing; the tray is caused to advance on the basis of an unloading signal after the cam plate is caused to slide in one direction and the drive chassis is moved downward around both the pivotal supporting axes; the drive chassis is moved upward on the basis of a loading signal around both the pivotal supporting axes by causing the cam plate to slide in the other direction after the tray is retreated; one of both the pressing pieces is formed so as to be resiliently displaced with a protruding portion erected at the tip end thereof, and the inner side of the protruding portion is made into an inclined pressing plane which is inclined sideward at a prescribed angle so that it is turned downward so as to be widened outwardly; the front part side edge of the upward moving drive chassis is formed so as to be resiliently brought into contact with the inclined pressing plane thereof, and the rear end face of the protruding portion is made into an inclined guide plane that is turned downward at a prescribed angle in the forward direction to be inclined downward so as to be widened outwardly; and the inclined guide plane is devised to be resiliently pressed up from the front edge of the drive chassis incorporated in the casing.
