Abstract

PURPOSE:To print date and time independently of a control software of a host computer to perform a history management of paper by a method wherein a real time clock is incorporated in a printer device so that the printing of date and time can be controlled independently by the printer every time when a page feed is conducted. CONSTITUTION:As a date and time setting operation to a real time clock 2, a date and clock setting switch is operated to the present date and time by referring to a date and time indicator on an operation indication part 4. After that, the real time clock 2 starts counting and continues counting. When receiving a page feed control code from a host computer, a control part 1 instructs a printing part 6 to conduct a page feed action, reads the data and time from the real time clock 2 on the first line after the page feed action, instructs the printing part 6 to print the read value, and instructs a line feed action. Printing data received from the host computer through an interface part 5 is printed from the second line.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device, and more particularly to a printer device that has a built-in real-time clock and controls printing of date 1 and time.

[Conventional technology]

Conventionally, this type of printer device does not have a built-in real-time clock, so the date is printed on the printing paper.

When printing the time, the host computer takes the date and time as print data and prints it at a predetermined position.

[Problem to be solved by the invention]

The above-mentioned conventional printer device receives and prints date and time data from a host computer, so it has the disadvantage that it cannot print date and time unless the host computer's control software instructs it to print. be.

[Means to solve the problem]

The printer device of the present invention includes a real-time clock that measures the date 1 time, an operation display section that instructs the setting of the date 1 time of the real-time clock and a print mode for the date 1 time, and a printer device that measures the date 1 time from the operation display section. When the print mode is set and the printing mode is set, the control unit receives the page break control code from the host computer and prints the date and time of the real-time clock on the blank area of the printing paper. There is.

〔Example〕

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

The interface section 5 performs level conversion, such as Centronics, for receiving control codes and print data from the host computer.

The operation display section 4 has a switch for instructing the real-time clock 2 to set the date 1 time and a display device 6 for displaying the date 9 time via the control section 1. It has a print mode switch that instructs printing of date 1 and time.

The control section 1 controls the reception of control codes and print data from the host computer via the interface section 5, and controls the printing section 6 based on the received control code and prints characters and the like based on the received data. Also, the control section 1
reads the date 1 time from real time clock 2,
The date 1 time is displayed on the date 9 o'clock II display of the operation display section 4.

Battery backup section 3 is real time clock 2
DC power is supplied to the printer, and even when the power to the printer is cut off, the timekeeping operation of the real-time clock 2 is backed up by the battery.

Next, the operation of the present invention will be explained.

First, as a setting operation for setting the date 9 time on the real-time clock 2, operate the date setting switch while looking at the date 1 time display on the operation display section 4 to set it to the current date 9 time. Thereafter, the real-time clock 2 shall start and continue its timekeeping operation.

Further, the following explanation assumes that the date 1 hour printing mode switch on the operation display section 4 is pressed to instruct the control section 1 to operate in the date 1 hour printing mode.

When the control unit 1 receives a page break control code from the host computer, it instructs the printing unit 6 to perform a page break operation, reads the date and time from the real-time clock 2 on the first line after the page break operation, and prints the value. After instructing the printing section 6 to print the following, a change operation is instructed.

The print data received from the host computer via the interface section 5 is printed from the second line.

FIG. 2 is an example of printing on the first and second pages, and shows an example in which the date and time are printed on the right corner of the first line of the printing paper 7 after a page break.

〔Effect of the invention〕

As explained above, the present invention has a built-in real-time clock and controls the printer to print the date and time at every page break, thereby printing the date and time independently of the control software of the host computer. Paper history management becomes possible.

Claims (1)

[Claims] In a printer device that prints by receiving control codes and print data from a host computer, a real-time clock that measures date and time, and an operation display unit that instructs the setting of the date and time of the real-time clock and the printing mode of the date and time. When the mode is set to print the date and time from the operation display section, the control code for page break is received from the host computer and the date and time of the real-time clock are printed in the blank area of the printing paper. A printer device characterized by comprising a control section.
