Abstract
PURPOSE: To reduce the cost as well as to simplify the constitution by sharing the photoelectric conversion element in case the remote control unit is installed to the record player incorporating the optical record disk detector.
CONSTITUTION: Through-holes 2a, 2b and 2c are provided to turntable 1, and the light beams the amplitude of which are modulated to be indentified to each other enter photoelectric conversion element 4 through holes 2aW2c. The light beam sent from luminous element 6 of remote-controlled transmitter 5 is received at element 4 to secure identification for several different types of orders corresponding to the selected modulated frequency via switch group 7. In such constitution, the auto- player can share the light reception part of both the record disk detector and the remote control unit, thus realizing reduction of the component parts number and thus the cost reduction as well.
