Abstract:
1. A television with disc loader comprising: a slot for inserting and ejecting a disc; a slot-in type disc loader for taking in the disc inserted into the slot; a disc detecting section, including a light projecting element and a light receiving element, for detecting the disc when a light from the light projecting element to the light receiving element is interrupted by the disc when the disc is inserted into the slot; a microcomputer for determining an output of the disc detecting section and outputting a display control signal based on the detected result; and a displaying section for displaying a presence of the disc in the slot by a light emitting state of a light emitting diode that is lighted on or lighted out by the display control signal; wherein the light projecting element in the disc detecting section is driven by a continuous signal output from the microcomputer and projects a continuous light when the power of the television is turned ON, and is driven by a pulse signal output from the microcomputer and projects a pulse light when the power of the television is turned OFF, the power of the television being turned ON in response to the interrupting of the pulse light by the disc and the detection of the disc; the microcomputer determines the output of the disc detecting section as the pulse signal when the power of the television is turned OFF and the disc is not detected by the disc detecting section, and outputs the display control signal for lighting out the light emitting diode to the displaying section.
