Abstract

PURPOSE:To reduce a cost by providing a circuit for measuring a spacing operation, a sheet feeding operation and a printing operation, a memory for storing the measured results, and a display for displaying the stored contents, and controlling the operations by a microprocessor to count and print the stored result. CONSTITUTION:A microprocessor 1 reads data from counters 12, 13 or 14 each time when the operation of a space controller 3, a sheet feed controller 4 or a print controller 5 is finished, integrates it and stores it in a memory. Simultaneously, the content of the counter 12, 13 or 14 is set to zero for preparing next counting. Further, a CPU 1 reads data from a conducting time counter 15, integrates and stores it in a memory 16. Simultaneously, the content of the counter 15 is set to zero for next counting. The CPU 1 reads the corresponding data from the memory 16 according to a signal from a display 17, and the read data is printed on a printing sheet through the controllers 3, 4 and 5. Thus, a printer having high reliability and low price can be obtained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a dot impact serial printer device, and in particular to a spacing operation of a print head and a feed of printing paper.
The present invention relates to a printer device having a function of measuring operation time or number of operations such as operation or printing operation and displaying the results.

[Conventional technology]

In conventional dot impact serial printers, the operation time or number of operations, such as the spacing operation of the print head, the feeding operation of the printing paper, and the printing operation, are stored and displayed using dedicated counters or cages. This is done using

[Problem to be solved by the invention]

As mentioned above, in conventional dot impact serial printers, dedicated counters are used to store and display the operation time or number of operations for each operation such as spacing operation, printing paper feeding operation, and printing operation. Therefore, it has problems of high cost and low reliability.

[Means to solve the problem]

The dot impact serial printer device of the present invention includes a print head, a space motor that performs a spacing operation for the print head, a paper feed motor that performs a print paper feed operation, and a print driver that drives the print operation of the print head. a space motor driver that drives the space operation of the space motor; a paper feed motor driver that drives the paper feed operation of the paper feed motor; a print control unit that controls the operation of the print driver; a space control unit that controls the operation of the driver;
A dot impact serial printer device comprising: a paper feed control unit that controls the operation of the paper feed motor driver; and a microprocessor unit that controls the operations of the print control unit, the space control unit, and the paper feed control unit. a counting circuit that measures the number of operations or operation time of each of the print head, the space motor, and the paper feed shimo motor; a storage unit that stores each data measured by the counting circuit as f*/JI; and a display section that switches and displays the stored contents of the storage section, and is configured so that the contents stored in the storage section are printed on the printing paper by the print head under the control of the microprocessor section.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, an operation control unit 21 controls the operation of each part of the printer device as in the conventional case, and a count display unit 2 has the following functions:
It has a means for counting spacing operations, printing paper feeding operations, and printing operations of the printer, a means for storing the results, and a means for displaying the stored contents. The space control unit 3, paper feed control unit 4, and print control unit 5 control the space motor 9, paper feed motor 10, and print head 11 via the space motor driver 6, paper feed motor driver 7, and print driver 8, respectively. Control behavior. On the other hand, the stitch count circuits 12, 13, and 14 receive signals from the space control section 3, paper feed control section 4, and print control section 5, respectively, and measure the respective operation time or number of operations. The microprocessor (CPU) 1 controls the counting circuit 12 or 1 each time the operation of the space control section 3, paper feed control section 4, or print control section 5 is completed.
3'! or 14, and integrates and stores the data in the storage section. At the same time, each counting circuit 12 or 1
The content of 3 or 14 is set to zero, and the m content is set to zero for the order number of times to enable the next count.

The display section 17 can switch and display the stored contents of the storage section 16 by a human operation.

The CPU 1 controls the storage unit 1 by a signal from the display unit 17.
6, and this read data is sent to the space control section 3 and the paper feed control section 4.6. Then, via the print control section 51, the information is printed on printing paper attached to the printer device.

〔Effect of the invention〕

As explained above, the printer device of the present invention includes a circuit for measuring spacing operation, paper feeding operation, and printing operation;
It has a storage section that stores the measurement results and a display section that displays all the stored contents, and has the effect of being able to control the operation of each section with a microprocessor, count, and print out the stored results. Therefore, it is possible to easily know the operation time or number of operations without using a dedicated counter for each as in the past, which has the effect of providing a printer device with excellent reliability and low cost. be.
