US Patent 7590033 Optical disc reproducing apparatus

In an optical disc reproducing apparatus, when a stop key is pressed during reproduction of an optical disc, a resume function is activated, and a resume-on indication appears on a display device. When the resume-on indication goes out a predetermined time thereafter, a resume-indicating light-emitting device is lit. Thereafter, when a play key is pressed, resume reproduction is started. If, by mistake, a key other than the play key is pressed, a warning indication appears on the display device to indicate that a resume-on state is currently established, and also, if the pressing of the key is a first-time pressing, the pressing of the key is neglected.
