Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a printing control device for a printer that prints various data obtained by measuring instruments, etc. Specifically, the invention relates to a printing control device for a printer that prints various data obtained by measuring instruments, etc. The present invention relates to a printing item setting device for a printer that is capable of printing only items.

[Technical background of the invention]

For example, in measuring instruments that measure electrical characteristics,
Multimeters are available that can measure various characteristics such as current, voltage, and power with a single measuring device. Furthermore, in recent years, meters with built-in printers for storing these various measurement data and meters with terminals for printing output have also been provided.

[Problem that the invention attempts to solve]

Meters equipped with such a printing function are designed to record all measured data sequentially, and especially those with a built-in printer are designed to keep the printer small and make effective use of printing paper. Therefore, as shown in FIG. 4, for example, the printing paper 1 has voltage, current,
Active power (Watt), apparent power (VA), power factor (PF)
etc., multiple channels are printed for each item with narrow intervals between them.

If all of this information is needed, there is no problem, but if only some of the information is needed, it is necessary to extract the necessary information from this, which is not only inconvenient but also has the disadvantage of lengthening printing time and unnecessarily wasting printing paper.

Therefore, the purpose of this invention is to provide a printing item setting device for a printer that has a simple configuration and can print only desired items, thereby making it possible to shorten printing time and save printing paper. .

[Means for solving problems]

This invention is a printing item setting device for a printer that prints any item among a plurality of items each having a plurality of data. A keyboard that emits a position signal for sequentially setting the table position of the table memory and a print instruction signal for instructing printing of data at that position, and a keyboard that sequentially scans the table memory using the position signal and print instruction signal from this keyboard. and a control means for outputting the position information of the table memory and a print instruction signal, a first memory for storing all the data, and a control means for sequentially recalling the data in the first memory and outputting the position information and the print instruction signal from the control means. The present invention is characterized by having a processing circuit for setting data to be printed by the processing circuit, and a second memory for storing the items to be printed and the data from the processing circuit and outputting them to the printer.

[Effect]

For example, the table memory is set in a table in which items are set on the horizontal axis and channels are set on the vertical axis. During a printing operation, the control means first instructs the first channel of the first item. If you use the keyboard to specify whether or not to print this data,
When printing, the information is sent to the processing circuit by the control means. The processing circuit uses this information to
The data of the first channel of the first item in the memory is sent to the second memory and stored therein. If printing is not required, the data is not sent to the second memory. In the case of printing, the next position signal from the keyboard causes the processing circuit to direct the second channel of the same item,
It has an instruction as to whether to print or not, and if printing is not necessary, the processing circuit instructs the first channel of the next item in response to the next position signal from the keyboard. Thereafter, instructions are given as to whether or not to print each item in the same manner. As a result, the second memory stores only the data of items that require printing, and the printing operation of the printer can be performed using this second memory.

〔Example〕

Hereinafter, one embodiment of this invention shown in the drawings will be described. As shown in FIG. A forward button 17 that manually lights up the light emitting diodes 12, 13, 14, 15, and 16 in sequence, a backward button 18 that returns to lighting the previous light emitting diode, and printing data corresponding to the lighted light emitting diode. A print setting button 19 for instructing to print, a print unnecessary setting button 20 for instructing that the data corresponding to the lighted light emitting diode does not need to be printed, and a print operation button 21 for instructing the printing operation of the printer 11 are provided. The printer 11 is also provided with a paper outlet 23 through which printing paper 22 is sent out.

As shown in FIG. 2, the printing item setting device includes a first memory 31 that stores all data from a measuring device (not shown), and a first memory 31 that stores all data from a measuring device (not shown), and a first memory 31 that stores all data from a measuring device (not shown), and according to the items measured by the measuring device and the number of data, A table memory 32 that stores a table with items on the vertical axis and the maximum number of data through each item on the horizontal axis, a forward button 17, a backward button 18, a print setting button 19, a print unnecessary setting button 20, and a print operation button 21. A control means (hereinafter referred to as CPU) 34 composed of a microcomputer etc. that processes instruction signals from a keyboard 33 composed of etc.
It has The CPU 34 sends an instruction signal from the keyboard 33 to the table memory 32, sequentially scans the table of the table memory 32, and sends information from the table memory 32 to the processing circuit 35. The processing circuit 35 sequentially reads the data stored in the first memory 31, determines whether printing is required based on information from the CPU 34, and sends the data required to be printed to the second memory 36. The second memory 36 sends the information stored in the printer 37 to be printed by operating the print operation button 21. table memory 3
2 has light emitting diodes 12, 13, 14, 15,
A light emitting diode drive circuit 36 for lighting the light emitting diode 16 is connected thereto.

It is now assumed that the first memory 31 stores various data such as that recorded on the printing paper 1 shown in FIG. 4 described above. Therefore, table memory 3
2, a table is prepared in which items such as voltage, current, active power, apparent power, power factor, etc. are set on the horizontal axis, and channels and total values are set on the vertical axis. The CPU 34 first starts with this table memory 3.
2, the light emitting diode drive circuit 38 is driven to light the light emitting diode 12. That is, the operator is asked by lighting the light emitting diode 12 whether or not to print the voltage measurement value data.
When printing, the operator presses the print setting button 19 and instructs the CPU 34 to print. CPU3
4 receives this instruction signal, the processing circuit 35
Data representing the voltage is sent from the memory 31 to the second memory 36. Next, when the operator presses the forward button 17, the light emitting diode 13 is turned on to set whether or not to print the numerical data of the voltage channel 1 via the CPU 34, table memory 32, and light emitting diode drive circuit 38. If printing is required, press the print setting button 19 in the same way as above.
Press. This causes the processing circuit 35 to
1 to send the numerical data of voltage channel 1 to the second memory 36. Thereafter, print instructions for channels 2 and 3 are given in the same manner. When the settings for channel 3 are completed, the CPU 34 instructs the table memory 32 to move to the next item, the current print settings. At this time, the light emitting diode 12 lights up again. That is, the light emitting diodes 12, 13, 14, 15, and 16 are used for common display of each item. Printing is then set for this current in the same manner as for the voltage described above. Next, print settings are made for active power. It is assumed that printing is not necessary for the following apparent power. When the light emitting diode 12 lights up again for the fourth time, if you press the no-printing setting button 20, this item will be marked as no-printing.
The CPU 34 instructs the processing circuit 35 not to send the apparent power data to the second memory 36. Next, when the forward button 17 is pressed, the CPU 34 instructs the table memory 32 to move to the next item, power factor print setting. When an instruction is given to print this power factor as well and no need to print the remaining data, the second memory 36 stores voltage, current, active power, and power factor data, and only these data are printed by the printer circuit 37. The information is printed on the printing paper 22 from the output port 23 of the printer as shown in FIG.

In the above embodiment, if the printing unnecessary setting button 20 is pressed, this item is set as unnecessary printing and the CPU 34
However, only the channel of the corresponding item may be made unnecessary to be printed. This makes it possible, for example, to make it unnecessary to print only the data representing each item, or to make it unnecessary to print only the desired channels. In addition, the print setting button 19 is also used as the forward button 17, and the printing unnecessary setting button 20 is also used as the forward button 17.
Unless the button is pressed, it may be processed as a print instruction.

In the above embodiment, the printer is independent, but it may be integrated into the measuring instrument. In this case, the first and second memories 31, 36, table memory 32, CPU 34, and processing circuit 35 are A microcomputer in the measuring instrument may also be used.
