Abstract

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.

The physical circuit and its operation will now be explained based on FIGS. 3 and 4. First, the timer IC (

A constant voltage is generated by the constant voltage circuit 9, which is connected to terminal 18.
It is supplied to each part as VDD from the VDD.

Next, inside the timer ICti4, an oscillation circuit is installed.

Fortunately, terminals 9, 10.11 K are digital & W (to)
is connected to the decoder OIKmi. This digital EW (2) determines the frequency division ratio], and the sign tS・e at a &
Then, the frequency division ratio determined by these levels H and L is as shown in the table below.

Further, a transistor in series with a relay coil is connected to the terminal 12 via a resistor &-, and the relay coil is interlocked with an output contact. The collector of the terminal 12 is connected to the power supply, and the electric power supply I is connected to the two-color light emitting Ia.

Next, a decimal counter (b) is connected to the terminal 14. An initial reset circuit consisting of a resistor and a capacitor Cm is connected to the reset terminal of this decimal counter, and is reset when the power is turned on.

The outputs of the decimal counters 0A-D are converted into outputs of Ego~9010 types by the decoder, and this output is T

In this state 11I, the output Q of the terminal 12 turns off the transistor H (4i people), and the output ζFiH of the terminal 13 turns on the transistor (44B), causing the L
Driving power is given to EDI・～■1・.

Then, the oscillation circuit oscillates with the oscillation period determined by the selected resistor, and an output is generated from the output buffer with the frequency division ratio set by the digital controller (2).

For nine cycles, the oscillation circuit output is 100 x n (h is a variable frequency division number), and one cycle of H and L is repeated. First, the first %0 is H and the decimal counter generates an output, which is output to the 0 terminal of the decoder to cause LKDn to emit light. At the next H of %0, 11 emits light and this is LE

In this state, the output contact - is b-, indicating a connected state.

When the %Q010 repetitions are completed in this way, the Q at the terminal 12 becomes H, and the terminal 18 becomes LK.

This causes the transistor to energize the relay coil and switch the output contact to low.

Turn on the transistor (44A) and turn on LEDm~LID
m is driven, LEIlh~LEDI- becomes non-lit and changes color, the electronic switch (to) is switched, and it oscillates under the condition of the resistance (b) by V& and VRI. The circuit - oscillates. If the oscillation period in this case is made longer than before, the interval between changes in the output becomes wider as shown in FIG. That is, '[@oH, the period of L is much larger than before], and LiDm to LEDm sequentially emit light.

When this cycle continues, the cycle of time control is in, and the same operation is repeated as long as there is input power.

Such an operation can be performed by using the timer 1c (2), and during operation, the color development of the two-color light emitting device (Llij) (Incorporated) is determined by the operating state of the output contact. is determined, and by looking at the position of the emitting element (2), the passage of time in that state can be determined.

As described above, the present invention is provided with a two-color display element in which the output signal is switched and the color of light emitted is different from K to P. Therefore, the state of the output signal is made clear by the color, and also serves as a reference for the output signal. Since the elements are made to emit light one after another by counting clock signals, it is possible to clearly see the passage of time in that state.
