Description

[Detailed description of the invention] [Field of industrial application] This invention is a device with a data processing function that sequentially captures various data, prints the data, performs prescribed processing on the data, and prints the results. The present invention relates to printers, and more specifically, relates to a printer with a data processing function that can cancel part of captured data without performing predetermined processing.

[Conventional technology]

Electrical measuring equipment records the measured values of various samples or the sample identification symbols and measured values using a printer, and calculates their average value, total value, standard deviation value, etc. A printer equipped with a data processing function that prints these numerical values is provided. Measuring equipment equipped with such a printer is convenient when measuring the electrical characteristics of a large number of samples because it not only prints out the individual characteristics, but also automatically calculates and prints out the average value, etc. be.

[The problem that the idea aims to solve]

However, in such printers,
Data that has been entered incorrectly will also be processed, which will affect the calculation of average values, standard deviation values, etc.

Therefore, the purpose of this invention is to provide a printer with a data processing function that has a simple configuration and can cancel the data if an incorrect input is made during data collection, so that the data will not be treated as data for subsequent data processing. .

[Means to solve the problem]

According to this invention, in a printer having a function of sequentially printing out continuously input data and performing predetermined data processing, a storage means for sequentially storing data via the central processing means, and a data storage means are provided. The central processing means includes a central processing means for controlling the storage means to store and erase data and perform predetermined data processing, and a keyboard means for instructing the central processing means to print out data, cancel data, process data, etc. When storing data, the means stores the data by incrementing the address of the storage means in the order of input, and in response to a cancel instruction from the keyboard means, sequentially erases data from the last stored address. , a printer with a data processing function is provided, which is characterized in that the address is controlled to be decremented.

〔Example〕

An embodiment of this invention shown in the drawings will be explained below. Data from a measuring instrument etc. is input to the input terminal 1.
The input/output support (hereinafter referred to as I/O port) 2 is applied to a central processing means (hereinafter referred to as CPU) 3 composed of a microcomputer or the like. The CPU 3 is connected to a ROM 4 that stores information necessary for processing system programs and input data for the CPU 3, and a RAM 5 that stores input data under the control of the CPU 3. I/
Connected to the O port 2 are a keyboard 6 for instructing writing or reading of input data, or data processing of the input data, and a printer 7 for printing out data. The keyboard 6 is
It consists of a print key, a cancel key, a stop key for instructing data processing, etc.

Next, the functions and operations of these structures will be explained with reference to the flowchart shown in FIG. Data from an external device such as a measuring instrument is input to the input terminal 1, and this data is input from the I/O port 2 every time the print key of the keyboard 6 is turned on, and the CPU 3 stores this data in the RAM 5. . Every time CPU3 stores data, it
Control is performed to increment 5. below,
Every time data is applied to input terminal 1, RAM
5, those data are stored while being incremented. On the other hand, the CPU 3 instructs the RAM 5 to store the data and also instructs the printer 7 to sequentially print out the data.

While monitoring the printed data, the operator presses the cancel key on the keyboard 6 when data that seems unnecessary or noise is printed out. Cancel signal is CPU
3 to RAM 5, the last stored data is cleared, and the memory address is decremented. If you press the cancel key again, the previous data will be cleared and the memory address will also be decremented. Next, when the print key of the keyboard 6 is turned on to store new data, the new data is stored in the cleared memory address and printed out. Therefore, erroneously input data can be canceled at that point by monitoring what is printed out by the printer 7, and it is possible to prevent unnecessary data from being processed in subsequent data processing. Once the specified data entry is completed,
If you press the stop key on keyboard 6, CPU 3
performs predetermined data processing, prints out the results, and clears all data stored in RAM 5.

Note that the data from input terminal 1 is stored in RAM 5 along with a serial number representing the input order in the order of input.
and print it out.
Controls CPU3 and when a cancel signal comes,
By printing out the serial number attached to the data and an indication indicating the cancellation, it is easy to find out which data has been cancelled.

[Effect of idea]

As described above, in the printer with data processing function of this invention, when the CPU stores data, the address of the storage means is incremented in the order of input, and in response to a cancel instruction, the data is stored last. Since the control is configured to sequentially erase data starting from the address that was entered and then decrement the address, data that has been entered incorrectly during data processing can be easily removed by operating the cancel key. The data can be erased immediately, and subsequent data processing can be performed using only the desired data.
