PURPOSE:To obtain a timer device which is capable of exactly showing whether an output state is on or off, namely, the time passing in its state, by providing a dichromatic display element whose color development is switched by existence of an output signal. CONSTITUTION:On a panel face 20 of the front of a body case 19, both an on- time setting control 21 and an off-time setting control 22 are provided, and on its upper part, a dichromatic light emitting LED24 which becomes a dichromatic display element consisting of 10 elements 23 is provided in one lateral row. This dichromatic light emitting LED24 consists of series of LED10-LED19 and LED20-LED29 for selectively displaying red or green, and each element 23 is combined, for instance, such as LED10 and LED20, and LED11 and LED21. By seeing color development of the dichromatic light emitting LED24, an operating state of an output contact is discriminated, and by seeing a position of the element 23 which is emitting light, the time passing in its state is discriminated. A state of an output signal becomes clear by a color, and also the time passing is grasped exactly since the element is made to emit light in order by counting a clock signal which becomes a reference of the output signal. |
