PURPOSE:To prevent voltage changes avoiding duplication of the driving by starting the signaling of time after the driving of a load driving means ends when the starting time of a signaling means is reached during the driving of the load driving means such as printer and lighting apparatus. CONSTITUTION:In a small electric computer with a printer, a CPU1 outputs an R/W signal to an input control section 2, a display control section 3 and a print control section 4 while outputting a print start signal S to the print control section 4 and a busy signal (b) is inputted during the printing operation from the print control section 4. While the print operation is executed at the printing section 7, the melody sound fails to emit. But within 5sec after the time signaling time is reached, the print operation ends and the signaling starts as soon as the output of the busy signal (b) vanishes. In addition, when the print operation is executed when 5sec passes after the regular time is reached, no time signaling is done thereby preventing adverse effect on the time signaling sound or the like. |
