Patent ID: 7939776

Claim:
A disc device, comprising: a switch provided with a contact point adapted to come out from and to be pressed into a switch body; an information processing section which includes a pickup; a base section in which the information processing section is disposed; and a drive section which drives the base section to swing, the drive section including: a motor, and a cam member in which a rack portion being meshed with a gear mechanism to receive a driving force of the motor via the gear mechanism and a cam portion are formed integrally with each other, the cam member being formed with a cam surface that presses the contact point and non-cam surfaces that allow the contact point to come out and being arranged to reciprocate in directions intersecting with an in-and-out direction of the contact point of the switch, the non-cam surfaces being respectively provided at both ends of the cam surface in a reciprocating direction of the cam surface, wherein: the switch is in one state of “On” and “Off” when the contact point is at a position in contact with the cam surface and is in the other state of “On” and “Off” when the contact point is at positions corresponding to the non-cam surfaces, in the vicinity of the non-cam surfaces, the cam surface is provided with a switching unit that changes a direction of the contact point when reciprocation of the cam member is inverted, the switching unit is a rib which is formed in a rectangular shape, and the contact point has a substantially triangle shape with an end portion which is inclined as the cam member reciprocates.
