PURPOSE:To obtain a timer which can record sound or picture over a full range of time set by a timer setter without being influenced by rise time or time error of the drive timer of an audio apparatus. CONSTITUTION:A time required for rising the drive part of an audio apparatus and a time required for compensating timer clock errors are used as correction times to compare 4 a time 2 ahead of a current time by a correction time with a timer start set time 5, and a time 3 behind the current time by the correction time with a timer end set time 6, thereby issuing a control signal to a drive circuit. |
