Abstract
PURPOSE: To perform the time-limiting and adjustment of sound volume with a small-sized constitution by shifting and selecting a timer counter and a sound volume counter and making an indicating device, etc. operate correspondingly.
CONSTITUTION: When a shifting switch 1 is connected to the side of a contact point 1b, AND gates 2 and 3 are opened by a high-level output, while the counter 4 for a timer is set to be in the state of nonoperation and a shifting circuit 12 selects the sound volume counter 9. And, corresponding to the operation of switches 7 and 8, the counter conducts up or down counting, thereby sound volume controlling voltage corresponding to setting is generated, while the output of the counter 9 is decoded by a decoder 16 and the prescribed transistors Q1WQ7 of the indicating circuit 18 are made conductive, thus the sound volume is indicated by LEDD1WD7. Meanwhile, when the time-limiting mode is set through the intermediary of the switch 1, the counter 4 which is capable of being set initially is counted down by a pulse outputted by the counter 5 at every 10 minutes through the intermediary of the switches 7 and 8, the remaining time is indicated by LEDD1WD7. Since a part used for two purposes is much, the time-limiting and the adjustment of the sound volume can be performed selectively by a simple and small-sized constitution.
