DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a recorder,
More particularly, the present invention relates to a recorder that enables a display device to visually recognize the occurrence of a trigger.

[0002]

2. Description of the Related Art FIG. 5 is a block diagram showing an example of a prior art recorder having a printing function and a display function. Some recorders have only a printing or display function. In the figure,
Reference numeral 1 denotes an analog processing / A / D converter for inputting and amplifying a measurement signal and performing A / D conversion. The A / D converted signal is stored in the buffer memory 2 here. The digital signal stored in the buffer memory 2 is sent to the CPU 4 via the input / output port 3, and arithmetic processing such as four rules and Log is performed using a program and an arithmetic expression stored in the memory (ROM) 5. These calculation results are displayed on the display device 7 via the display control unit 6, and
Printing is performed on a recording paper (not shown) by a printing mechanism 9 via a print control unit 8.

Reference numeral 10 denotes a keyboard control unit.
For example, a chart speed, a channel to be displayed, and various parameters input from 1 are set. Reference numeral 15 denotes a trigger control unit, which prints a symbol stored in the memory (RAM) 5 when a trigger is generated by an external contact 16, a timer 17, an alarm 18, a communication input 19, or the like provided on the recorder. Prints on recording paper via

[0004] The symbol corresponding to each of the above-mentioned triggers is, for example, "GAIBU" if it is an external contact.
ON ”, if the timer is used,“ TIMER O
"LIMIT OVE"
R "," POWER DO "
WN ".

The symbol corresponding to such a trigger is written by the operator in the RAM of the memory 5 using the keyboard 11 when the recorder is used, and the occurrence of the trigger is recognized by the trigger controller 15. Then, the image is printed at a predetermined position on the recording paper via the print control unit 8.

[0006]

However, in the above-mentioned prior art, a symbol corresponding to the occurrence of a trigger is only printed on the recording paper, so that if the recording paper is not carefully observed, it will be overlooked. If the operator moves away from the recorder and works elsewhere, the recording paper is fed and folded after a certain period of time even if the trigger occurs, and the trigger is printed even if the symbol indicating the trigger is printed. There was a problem of not being aware of the occurrence. Further, when it is not desired to record the occurrence of the trigger on the recording paper, there is a problem that the occurrence of the trigger cannot be recognized.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a recorder having improved visibility of the occurrence of a trigger by displaying a symbol corresponding to the occurrence of the trigger on a display device when the trigger occurs. The purpose is to provide.

[0008]

According to the present invention, in order to attain this object, according to the first aspect of the present invention, a signal from an object to be measured is input, a predetermined arithmetic processing is performed, and the signal is displayed on a display device. In addition, in a recorder having a trigger function, a symbol corresponding to the type of the trigger is previously determined and stored in a memory, and when the trigger occurs, the symbol is displayed on the display device. And

According to a second aspect of the present invention, there are provided a function of inputting a signal from an object to be measured, performing predetermined arithmetic processing and printing the signal on recording paper, a function of displaying the signal on a display device, and a trigger function. In a recorder having a function, a symbol corresponding to the type of the trigger is stored in a memory in advance, and when the trigger occurs, the symbol is displayed on the display device. is there. Hereinafter, the present invention will be described in detail based on embodiments.

[0010]

FIG. 1 is a flowchart showing a processing flow of a recorder according to the present invention. The configuration of the recorder is described in claim 1.
In this configuration, the dashed line portion (print control unit 8 and print mechanism 9) of FIG. 2 described in the conventional example is removed. Claim 2 is the same as FIG. 2, and the description is omitted here. It is assumed that the symbol corresponding to the trigger is written in the RAM of the memory 5 by the operator using the keyboard at the start of use of the recorder as described above, and that the trigger generation is recognized by the trigger control unit 15. I do.

[0011] In Fig. 1, ~ indicates a processing flow. Here, in a state where no trigger is generated, the recorder performs a normal display. When a trigger occurs, the trigger control unit 15 recognizes the terminal from which the trigger is issued, and notifies the CPU 4 of the occurrence of the trigger. When a symbol is registered in the memory 5 for the trigger, the CPU calls the set symbol and displays it on the display via the display control unit.

For display on a display, for example, the following method can be considered. 1) FIGS. 2A to 2C show an example in which the entire display screen is replaced with trigger symbols, and shows a state in which the screen of the normal display (a) changes to a trigger generation state in (b).
(C) shows an example of a state in which the operator presses the clear key on the keyboard after visually recognizing the occurrence of the trigger and returns to the normal display before the occurrence of the trigger. If the trigger is generated continuously for a short time (for example, several seconds), the operator sequentially replaces another symbol by pressing the clear key.

2) FIGS. 3 (a) to 3 (c) show an example in which a trigger symbol display area is provided in a part of the display screen, and the screen of the normal display (a) is in a trigger generation state in (b). (C) shows two types of trigger symbols that can be displayed. For example, the upper row shows the first trigger symbol and the lower row shows the next trigger symbol. You. In this case as well, the operator presses the clear key on the keyboard after visually recognizing the occurrence of the trigger (a).
Return to the normal display of.

3) FIGS. 4A to 4C show examples in which the measurement results of three channels are digitally displayed on the screen.
The screen of the normal display (a) shows the state changed to the trigger generation state in (b), and in this case, the operator returns to the normal display of (c) by pressing the clear key of the keyboard after visually recognizing the trigger generation. Printing on the recording paper is performed as needed.

[0015]

As described above, according to the present invention, a symbol corresponding to a type of trigger is stored in a memory in advance, and when a trigger occurs, the symbol is displayed on a display device. Therefore, it is possible to realize a recorder with improved visibility of occurrence of a trigger.
