PURPOSE:To improve the reliability of a displaying function with simple constitution by providing a slider and terminal plate to a moving part and fixed part respectively for disk reproeuction and by displaying a reproduction position according to their contact position. CONSTITUTION:The moving part and fixed part are provided with slider 20 and terminal plate 21 respectively, and terminal plate 21 is in parallel to the moving direction of the moving part and in freely slidable contact with slider 20. Further, the widths of conductive foil 22 of terminal plate 21 and the part where no conductive foil 22 is provided, and their interval are calculated on the basis of the relation between the extent of the movement of the moving part and the reproduction time of disk 3. Then, a current is flowed through slider 20 and terminal plate 21 and each conductive coil 22 and the adapted time display device of display part 24 are connected together to display the reproduction position of disk 3 or that ot pickup 5 for detecting a signal from disk 3. |
