Abstract

PURPOSE:To exchange an ink ribbon establishing the lower limit of the printed character quality of a printer. CONSTITUTION:A memory part 18 for the number of characters within a printing limit is installed, and a hit number determined from printing quality is set. The number of printed characters is output from a printing control part 11, and a control part 13 for counting printed characters stores the accumulated number of printed characters in a memory part 14 for the number of printed characters to display the number on a display part 16 for the number of printed characters. When the accumulated number exceeds the printing limit for the number of printed characters, an alarm signal is displayed on an alarm part 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device, and more particularly to a printer device which uses an ink ribbon impregnated with printing ink to print according to a printing command from an information processing device.

[0002]

2. Description of the Related Art Conventionally, a printer of this type only prints in accordance with a print command from a printer control unit of an information processing apparatus, and visually judges whether or not a print character is thin, and replaces an ink ribbon. It is supposed to do.

[0003]

The above-described conventional printer apparatus has a drawback that the minimum print quality is not constant because there is a difference in the judgment standard because the judgment of the ink ribbon replacement timing depends on the individual feeling. is there.

[0004]

A printer device of the present invention is a printer device for printing using an ink ribbon impregnated with a printing ink, and the number of characters to be printed each time a print command is issued from an information processing device. And a print character number display means for displaying the print character number stored in the print character number storage means, a print limit character number storage means for storing a preset print limit character number, and the print character number. Control means for comparing the accumulated number of characters every time the number of printed characters of the storage means is accumulated with the limit number of characters stored in the print limit character number storage means, and for displaying an alarm when the accumulated number of characters exceeds the limit number of characters. It is constituted by having.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The embodiment shown in FIG. 1 shows a printer device 1 and a workstation 2 which gives a print command to the printer device 1. The printer device 1 includes a print control unit 11, a print mechanism unit 12, a print character number counting control unit 13, and a print character number. The workstation 2 includes a storage unit 14, a clear unit 15, a print character number display unit 16, an alarm unit 17, a print limit character number storage unit 18, and a setting unit 19, and the workstation 2 is configured to include a printer control unit 21. ..

With the above configuration, when the print control unit 11 receives a print command from the printer control unit 21, the print control unit 11 decodes the print command and at the same time gives the character data to the print mechanism unit 12 for printing. On the other hand, the print control unit 11 counts the number of characters and the number of symbols and codes in the character data for each print command, and outputs it to the print character number counting control unit 13. When the print character number counting control unit 13 receives the number from the print control unit 11, the print character number storage unit 1 reads the number stored in the print character number storage unit 14, adds the given number, and again returns the print character number storage unit 1.
4 and the added number is given to the print character number display section 16, and the added number is compared with the number stored in the print limit character number storage section 18, and the added number is stored in this storage section. When the number stored in 18 is exceeded, an output is given to the alarm unit 17. The number-of-printed-characters display unit 16 holds and displays the numerical data given by the liquid crystal numerical display. The alarm unit 17 emits light to call attention while the output is given from the print character counting control unit 13 by the issuing diode. The setting unit 19 is means for setting the number of strokes in the print limit character number storage unit 18 when the limit number of strokes of the ink ribbon is determined. The clear unit 15 is means for clearing the contents of the print character number storage unit 14 to 0 when the ink ribbon is replaced.

[0008]

As described above, according to the present invention, the printer sets a print limit number of characters, a counter for storing the total number of print characters is provided and displayed, and when the total number exceeds the limit number of characters. By displaying the alarm, it is possible to obtain the replacement expectation and the replacement instruction of the ink ribbon, so that it is possible to obtain a constant print quality.
