Abstract

PURPOSE: To facilitate an easy setting of the timer and then securing an accurate analog display of the residual time, by displaying the set time and the residual time bu turning on and off continuously a number of units of LED provided around a knob and in accordance with the setting of rotary movement of the knob.
CONSTITUTION: With turning of the setting knob 1, the switch-ON contacts S1... of each stage of the shift register 7 of 24 stages or the like are shifted. And thus the LED drive transistor T is turned on. As a result, the LEDL1... corresponding to the output of register 7 are turned off by the output of the register 7 and the intermediate output of the divider 4 and via the AND gates A1...; while other LEDL1... corresponding to the switches S1... are turned on continuously. The blinking LEDL1... shift via the register 7 and as the time elapses, and the set time and the residual time are displayed accurately and in an analog and easy-to-see way. In this constitution, the setting of the timer time, the alteration of the time after setting and the like is performed easily in a short time.
