Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an electronic timer such as a digital timer, and more particularly to an electronic timer with a display for displaying a clocked time (prior art). An electronic timer, for example, one that is commonly used as a digital timer, has four electronic timers in the same case.
There is a device that has a 6-digit time display and has one time-limited output.

(Problem to be solved by the invention) Conventional digital timers like this are configured to display a fixed number of digits in the same case, so for example, if you want to use a timer with a large, easy-to-read 2-digit display. In such cases, it is necessary to replace it with the 4- to 6-digit timer mentioned above, or to manufacture a new 2-digit timer as a special response, which increases the cost and makes the display difficult to read. There are some difficulties.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an electronic timer that can easily correspond to arbitrary digits and has an easy-to-read display.

(Means for Solving the Problems) In order to achieve the above object, the electronic timer of the present invention has an input/output unit and a one-digit display section, and the input/output unit is arranged in parallel with the input/output unit. The input/output unit is configured with a timer unit that can be connected to and separated from the unit in multiple stages, and the input/output unit receives a control signal and receives a matching output from all the timer units connected to the input/output unit. The timer unit measures time based on the setting operation and the control signal from the input/output unit, and the one-digit display unit outputs a timer output. It is characterized by displaying the corresponding digit and outputting a matching output to the input/output unit when a set time has elapsed.

(Function) According to the above configuration, by connecting the timer units each having a one-digit display section to the input/output unit in multiple stages according to the desired number of digits, the timer unit having the desired number of digits can be easily set. You will get it.

The electronic timer 1 of this embodiment has a single input/output unit 2.
and first to third timer units 4a to 4C, each having a one-digit display part 38 to 3C, and which can be connected to and separated from the input/output unit 2 in multiple stages, The display units 3a to 3C are capable of displaying a three-digit clock time. Note that the configurations of each timer unit 4a to 4C are the same.

Each timer unit 4a to 4C is provided with a plurality of connection pins 5a to 5C and corresponding jacks so that it can be connected to and separated from the input/output unit 2 in multiple stages. Also provided is a jack to which the pin 5a of the timer unit 4a is connected.

Each of the timer units 4a to 4a has two first . Second setting switches 6a-6c and 7a-7c are provided, respectively.

On the back side of the input/output unit 2, an input terminal for control signals such as a start signal and a reset signal, an output terminal for timer output, and a power supply terminal are provided.

FIG. 3 is a block diagram of this electronic timer l.

The input/output unit 2 includes a human input signal processing circuit 8 that shapes the waveform of control signals such as a start signal and a reset signal input from the outside and outputs the waveforms to each of the timer units 4a to 4C.
It is provided with an output circuit 9 which takes the AND of the coincidence outputs from each timer unit 48 to 4C and outputs a one-shot or bold output as a timer output.

Each timer unit 4a to 4C has an input circuit 10a to 10c to which a control signal from the input/output unit 2 is manually input, and first and second setting switches 6a to 6c, 7a to 7C for time range and time setting. An operation signal corresponding to a setting operation is given, and the input circuits 10a-10c
The L for the timer receives control signals from and performs timekeeping operations and display control of the display sections 3a to 3C based on these signals.
The output circuits 12a-+2C each output a coincidence output when the measured time matches the set time.

Next, the operation of the electronic timer I having the above configuration will be explained based on the time chart shown in FIG.

In this embodiment, when the three timer units 48 to 4C display the number of seconds in three digits, the first timer unit 4a displays the one digit, and the second timer unit 4b displays the number of seconds.
A case will be described in which the 0 digit and the 100 digit are respectively displayed by the third timer unit 4c.

FIGS. 4(A), (C), and (E) show the 3rd. Second. The operations of the first timers 4c, 4b, and 4a are shown in FIGS. 4(B), 4(D), and 4(F). Second. The coincidence outputs of the first timers 4c, 4b, and 4a are shown, and FIG. 4(G) shows the AND signal of the coincidence outputs.
An example is shown in which the set time is 111 seconds.

First, in a state where each timer unit 4a to 4c is connected to the input/output unit 2 as shown in FIG. 1, the first setting switches 63 to 6 for time range setting are turned on.
c, each timer unit 4a to 4c is set to 1, 10,
Each timer unit 4a to 4a is set to 100 times, respectively, and the second setting switches 73 to 7C for time setting are used to set each timer unit 4a to
In 4c, the setting time of the corresponding digit, in this example, is set.

This allows each timer unit 4 to respond to the start signal.
A to 4c start counting time and start displaying each digit.

That is, the first timer unit 4a repeatedly performs the timer operation shown in FIG.
A coincidence output is output as shown in FIG. 4(F).

The second timer unit 4b repeatedly performs the timer operation shown in FIG. 4(C) on a scale of 0 to 100 seconds,
Every time the set time of 10 seconds shown by the broken line is reached, a coincidence output for 10 seconds is output as shown in FIG. 4(D).

The third timer unit 4C performs the timer operation shown in FIG. 4(A) on a scale of 0 to 1000 seconds, and reaches the set time of 100 seconds shown by the broken line.

Then, as shown in FIG. 4(B), a coincidence output is output for 100 seconds.

Further, each timer unit 48 to 4c has display sections 3a to 3.
The clock time of each corresponding digit is displayed in c.

The input/output unit 2, to which the outputs of the timer units 4a to 4C are given, calculates the logical product of each matching output and calculates the timer output based on this logical product, as shown in FIG. 4(G). Output.

By connecting the timer units 43 to 4C having the one-digit display portions 3a to 3C to the turnout crab knit 2 in this manner, it can be used as a timer having a three-digit display portion.

In the above embodiment, the case where the timer is used as a three-digit timer has been explained, but according to the present invention, the input/output unit 2
By arbitrarily selecting the number of timer units 4a to 4C connected to the timer unit, it is possible to easily support a timer with a desired number of digits, such as 1 digit, 2 digits, 4 digits, etc., at low cost. Moreover, even with diffraction, the sizes of the display sections 3a to 3C can be maintained at a constant size that is easy to see.

(Effects of the Invention) As described above, according to the present invention, the electronic timer is composed of an input/output unit and a timer unit having a single-digit display unit that can be connected and separated in multiple stages to the turnout crab unit. Therefore, by connecting the timer units to human output units in multiple stages according to the desired number of digits, an easy-to-read timer with the desired number of digits can be obtained easily and at a lower cost than before. It will be done.
