PURPOSE:To provide a programmable timer which enables the ON or OFF turning by the last source determined finally after selections by providing a last source memory connected to a control circuit and a memory for control sources. CONSTITUTION:When a control circuit 1 rewrites a timer ON time memory 3 by the operation of a keyboard 8, the control circuit 1 reads out and writes the contents of a last source memory 11 into a source controlling memory 10. At this point, the source controlling memory 10 gives the same as the last source memory 11. The last source memory 11 has a source currently selected written thereinto. This memory is equivalent to a tuner, a deck, a player and the like in an audio stereo set and the last source to a band, a frequency and the like currently received in a tuner. This enables the rewriting of the contents of a memory for controlling sources simply by setting the time for turning ON or OFF of a programmable timer with the operation of a keyboard thereby ensuring the turning ON of the timer with the last source when turning ON it. |
