Abstract

PURPOSE:To confirm the image and a registration code of a registration character by providing a section for displaying a character in 24-dot matrix, a registration character setting section, a registration character buffer for storing the image and registration code of the character, and a control section for converting the image into liquid crystal displaying data and sending it. CONSTITUTION:If a liquid crystal display function mode of a registration character is selected when a select switch at a setting section 101 is deselected, a tile of liquid crystal function is displayed on a display unit 103 for displaying a character in 24-dot matrix, a starting registration code is set therein, and then a resource waiting state sustains until the select switch or an LF switch is depressed. When the select switch is depressed, the printer is released from this function mode. When the LF switch is depressed, data is read from a registration character buffer 104, and converted to a liquid crystal displaying data, and the code, the image of the character are displayed on the unit 103. Then, next registration code is set, and the resource waiting state sustains until the select or LF switch is again depressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer with a liquid crystal display function, and more particularly to a printer with a liquid crystal display function capable of simultaneously displaying an image of a registered character and a registration code on a liquid crystal and confirming the content of the registered character.

[0002]

2. Description of the Related Art Conventionally, this type of printer does not have a function of confirming an image of a registered character and a registered code by displaying on a liquid crystal display panel.

[0003]

Since this conventional printer does not have a liquid crystal display function for registered characters, try sending the code of the registered character that has been confirmed from the host device or printing the registered character once. Without it, there is a drawback that the image of registered characters and the registered code cannot be confirmed. Further, there is also a drawback that the paper for confirming the registered characters is wasted.

[0004]

A printer with a liquid crystal display function of the present invention comprises a display section capable of displaying one character in 24 dots vertically and horizontally, and a setting section for setting a registered character to be displayed in a liquid crystal on this display section. A registered character buffer that stores in advance an image of the registered character and a registration code, and a control unit that reads out the image and the registered code from the registered character buffer, converts the data into liquid crystal display data, and sends the data to the display unit. I have it.

[0005]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a printer showing an embodiment of the present invention.

A liquid crystal display function mode of registered characters and a registered character code to be checked are selected from the setting section 101. The control unit 102 converts the corresponding registered character code into the conversion unit 1.
Then, the control unit 105 controls to transfer the data converted by the conversion unit 105 for liquid crystal display to the display unit 103. The registration character buffer 104 contains registration codes and images of registration characters. The conversion unit 105 reads an image corresponding to the registered character code received from the control unit 102 from the registered character buffer 104 and converts it into liquid crystal display data. Display unit 103
Is a liquid crystal display panel that receives data converted for liquid crystal display from the control unit 102 and displays a code and image of registered characters.

FIG. 2 is a flow chart showing the control operation in FIG. This function is enabled when the registered character LCD display mode is selected during deselection, and the LCD display title is displayed on the LCD panel. At this time, a start registration code is set internally, and a resource waiting state is entered until either the select switch or the LF switch is pressed.

If the select switch is pressed (Ye
At the time of s), it becomes a selection state, exits from this function mode, and ends. When the LF switch is pressed (Yes), the data is read from the registered character buffer and converted into data for liquid crystal display, and the code and image of the registered character are displayed on the liquid crystal display panel. After that, the next registration code is set internally, and the resource standby state is entered until the select switch or the LF switch is pressed again.

FIG. 3 is a partial top view showing an example of an operation panel as a means for selecting the liquid crystal display function mode of the registered character in FIG. The select switch 304 is a switch that switches between a select state and a deselect state each time it is pressed. When the lamp in the switch is lit, the select state is shown, and when it is off, the deselect state is shown. Since various functions can be selected by pressing the function switch 302 in the deselected state, the selection of the liquid crystal display function mode of the registered character can be included in this. The liquid crystal display function mode of the selected registered character can be confirmed by the liquid crystal display panel 301 having a configuration of one character vertical and horizontal 24 dots, and by pressing the LF switch 303, the content of each registered character can be confirmed.

FIG. 4 is a diagram showing an example of the liquid crystal display of the display unit in FIG. 1, and the LF is displayed during the liquid crystal display function mode of the registered character.
Each time the switch 303 is pressed, the liquid crystal display changes. The liquid crystal display 401 is a title display indicating that the liquid crystal display function mode of the registered character is selected.

[0011]

As described above, according to the present invention, the image of the registered character and the registration code are displayed on the liquid crystal at the same time. Therefore, the image of the registered character and the registration code can be easily confirmed without printing on paper. There is an effect. Also,
This also has the effect of preventing loss of paper.
