As disclosed in Japanese Patent No. 386, etc., a card reader reads a member number, a credit company, a business type code, etc. magnetically recorded on a credit card, and the presenter of the credit card is the registered person (member). The transaction processing is started by collating whether or not, and keying in the sales (transaction) amount of the product or the like.

At this time, the input data (numerical value, etc.) such as the sales amount is displayed in a horizontal row on the display unit such as a liquid crystal display panel. The maximum number of digits that can be displayed on this display is
Considering that the operator can easily see the numbers and letters (including letters, letters, letters and letters, etc.) on the display, and the frequency of the number of digits in the input string, It was set to 6 to 8 digits.

When the number of digits of the input character string exceeds the maximum displayable number of digits on the display unit, there is a problem that the input cannot be further performed or the first input character disappears from the display unit in order. It was In order to eliminate this inconvenience, a changeover switch for changing the size (character size) of characters displayed on the display unit and changing the maximum displayable digit number is provided, and the maximum displayable digit in the large-sized font is provided. When inputting a character string having a number of digits larger than the number, it is dealt with by switching to a font of a smaller size and doubling the maximum displayable digit number of the entire display unit.

However, if the size of characters on the display unit is reduced at once, the size of the last input character also becomes smaller, which makes it difficult for the operator to see the characters. In addition, the operator can select the number of digits of the character string to be entered, or decide whether to endure with the large character size or the small character size, and operate the display digit number changeover switch either one in advance. There was also the problem of having to choose.

It is an object of the present invention to provide a display device that solves the above technical problems.

Reference numeral 28 is a display character number counting unit for counting the number of characters to be displayed, and reference numeral 29 is the display unit 1.
A display character string creation controller for determining the size of the character to be displayed in 1 and sequentially sending the character signal of the character to be displayed, and the reference numeral 30 is a character size storage unit that stores data regarding the size of the character. is there. In this embodiment, the character size has two types of character size, full-width and half-width, which will be described below. The character size storage unit 30
Character fonts (characters) such as alphanumeric characters, European characters, and Katakana characters of different sizes are stored in the character size. In this case, the character memory 26 is not provided, and the character size storage unit 30 stores characters of a predetermined size. You may select and pull out a code.

Reference numeral 31 is a liquid crystal element (LCD) panel or electrochromic (ECD) panel in the display unit 11.
In the embodiment, the display element is a panel or the like, and in the embodiment, 6-digit characters (numerals) are arranged in a horizontal row in a standard character size (full-width), and 12-digit characters (numeric) in the case of half-width.
The display light emitting portions are arranged in a matrix dot shape so that they can be arranged. In addition, when displaying a pattern of one full-width character with 16 dots in the vertical direction and 16 dots in the horizontal direction, this number of dots is a half-width character size (the full-width character size is the same as the vertical size, but the horizontal size is half Character), a pattern of one character can be displayed with the number of pixels of vertical 16 dots × horizontal 8 dots.
The number of full-width dots may be 24 × 24 dots. The vertical and horizontal drive circuits 32 and 33 are driven by a signal from the display character string creation controller 29 to display a predetermined character string on the display element 31 in a predetermined character size.

The central processing unit 24 writes / reads data to / from the RAM 27 based on the program of the ROM 25, and at the same time, the display unit 11, the keyboard 4, the printing unit 19 and the analog telephone line modulator / demodulator (modem).
Controls various input / output operations such as. When the central processing unit 24 receives a key input from the ten-key unit of the keyboard 4, the RO
According to the control program of M25, a character input signal is sent to the display character number counting unit 28, and the display character number counting unit 28 counts the display character number and sends the result to the display character string creation controller 29. The display character string creation controller 29 compares the number of characters that can be displayed at present with the number of input digits, and determines how many upper digits of the display digits should be displayed with a smaller character size. And a character size digit selecting means. A character having a size corresponding to the determination is selected from the character size storage unit 30 to create a display character string. The central processing unit 24 displays a predetermined display character string on the display 11.

FIG. 4 is a subroutine flow chart showing a control processing procedure of the embodiment, which will be described below based on this. That is, it is determined whether or not there is a character input from the keyboard 4 after the start (step 401), and if there is an input, it is determined whether or not the display clear key is pressed (step 402), and the display clear key is displayed. Is pressed (yes
In s), the input digit clear and the display character string clear are executed (steps 403 and 404), and the display on the display unit 11 is cleared (step 405).

When the display clear key is not pressed (no) in step 402, the number of input digits is increased by one digit in accordance with the number of input characters in step 401 (step 40).
6), the number of characters that can be displayed in the input digit and full-width size n
(In the embodiment, n = 6) is compared (step 407).
When the number of input digits is less than the number n of characters that can be displayed in the full-width size (no), in order to display all the digits in the display element 31 in the full-width size, the display character string creation controller 29 uses the full-width size character string. (Step 40
8) In response to this, characters such as numbers are displayed in full-width character string in the order entered on the keyboard 4 (step 405). For example, when inputting characters of 6 digits or less,
As shown in FIGS. 5A and 5B, all the characters are displayed in full-width size.

In step 407, when the number of input digits is larger than the number n of character displayable digits in the full-width size (yes
), In step 409, it is determined whether or not the number of digits that can be displayed in half-width size is 2n or less. Here, when it is judged that the value exceeds 2n in the above step, the display is impossible (overflow of the number of digits) even with the half-width size, so an error process is performed (step 410). When it is determined in step 409 that half-size characters can be displayed (yes), in step 411, the digit part of a predetermined digit or more is set to half-size, and the remaining lower digit parts are set to full-size. The calculated display character string is created and displayed on the display 11 (step 405). In the calculation in step 411, for example, the upper digit portion of (input digit number-n) x 2 digits is set to a half-width size, and the lower digit portion of (2n-input digit number) is set to a full-width size. Create a display string. According to this calculation, in the case of a 7-digit display string character, the upper 2 digits are half-width characters, and the remaining lower 5 digits are full-width characters (see FIG. 5 (c)), and in the case of 8 digits Indicates that the upper 4 digits are half-width characters and the remaining lower 4 digits are full-width characters (see FIG. 5D).
In the case of digits, the first 10 digits are half-width characters and only the last digit is full-width characters (see FIG. 5 (e)).

The change control for reducing the character size is performed when the number of digits that can be displayed in the large character size is exceeded.
Except for the last input character, all other characters may be changed to a small character size all at once, or when the number of digits that can be displayed in a large character size is exceeded, the small character size will be changed for all digits. It may be changed all at once. The small character size may be about ⅔ instead of half-width.

Furthermore, the change to a smaller character size may be performed in two steps, such as full-width → half-width → 2/3 square. In another embodiment of the present invention, the present invention can be applied to a display device in various information processing devices, and it is possible to execute not only numbers but also Roman characters and Katakana characters.

[0021]

As is apparent from the above description, when the number of characters of the character string input by the input means is counted and it is determined that the number of input characters exceeds the number of displayable digits in the normal character size. , The character size is automatically determined from which digit, and the character display of other digit parts is automatically reduced accordingly, so that the character size is reduced from the beginning. Compared to the case, the operator can easily confirm the characters, mistakes such as reading mistakes can be reduced, and the character input work can be easily performed as compared with the case where the changeover switch is used in advance.
