Description

[Detailed description of the invention] The present invention relates to a display device that alerts an operator to an operator's attention by blinking the screen, and is applicable to a wide range of applications by making the blinking period variable. .

Conventionally, when this type of device blinks the screen, the blink period is fixed by a circuit.
In this case, the way the operator was alerted was changed by using several blink functions with different cycles, but even in that case, the individual blink cycles were fixed.

However, if these blink periods are fixed and the blink period does not suit the purpose,
The desired blink period must be obtained by circuit modification.

The present invention aims to eliminate these drawbacks of conventional devices.

In other words, conventionally, in order to change the blink period,
The frequency divider circuit for the blink signal was changed, but in the present invention, several types of signals divided from this frequency divider circuit are wired, and the blink signals can be easily switched by using a switch or the like. Change of cycle is made variable.

A detailed explanation will be given below with reference to the drawings.

FIG. 1 shows a conventional blink circuit in which a blink signal F is output from a frequency dividing circuit 1 having a fixed frequency division number in accordance with a blink master signal A. Figure 2 shows the blink circuit according to the present invention.
2 is a frequency dividing circuit, 2 is a changeover switch, A is a blink master signal, and B to E are blink signals. According to this circuit, the blink master signal A is input to the frequency dividing circuit 1 and becomes the blink signals B, C, D, and E.
These signals are switched by the blink period changeover switch 2 and output to the display circuit.

In addition, although the case where one type of blink signal is frequency-divided into four ways has been described above, the present invention is not limited to one type of blink signal, nor is it limited to frequency-divided blink signals to be switched. . In short, if it is possible to create several types of blink signals from one blink signal by some means and to switch between them, it can be generally used.

As described above, in the display device according to the present invention, the blink period can be easily changed using a switch or the like, and the display device can perform a blink function according to the purpose of use.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing a conventional blink circuit, and FIG. 2 is a diagram showing an embodiment of the device of the present invention. In the figure,
1 is a frequency dividing circuit, 2 is a changeover switch, A is a blink master signal, and B to F are blink signals.
