ABSTRACT:
A disk player, e.g. for a CD or DVD, generally includes a tray receiving the disk to be scanned and a so-called cam slider moved between an IN-position for purpose of scanning and an OUT-position for purpose of loading the disk. Therein the movements and the end positions of the tray and the cam slider have to be monitored for proper operation. To do this generally several switches or a special complicated switch are needed. It is an object to simplify the means for performing said monitoring operations for movements in different directions and especially to achieve this by means of a single simple switch, only. The cam slider is provided with a chamfer for moving a switch lever of the switch into a first position (a) and further is provided with a control lever including a switch actuating area for moving said switch lever into a second position (b) said control lever being pivotally mounted on the cam slider against the action of a spring. By this solution it is achieved that movements in different directions can be monitored by a single simple switch only.
