Description

[Detailed Description of the Invention] This invention relates to a display device for displaying the reading result in a character reading device that optically reads characters recorded on, for example, a form.

Generally, CRT displays, dot matrix display elements, printers, TTYs, etc. are used as means for expressing characters such as numbers, alphabets, and kana characters.

However, if such a display device as described above is used in a character reading device with a small number of characters to be read, it will be very expensive and impractical.

This idea was made in view of the above circumstances, and its purpose is to display the number without lighting up the decimal point when the reading result is a correctly read number in the character reading device. If it is an alphabetic character or kana character that has been read correctly, the decimal point lights up and the number is displayed.
By displaying unreadable numbers as numbers different from those shown above when unreadable characters occur, we have created a display device that can display readable characters and unreadable characters using only an inexpensive numeric display with a decimal point, reducing costs. This is what we are trying to provide.

An embodiment of this invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a character reading device that optically reads characters recorded on a recording medium, such as a form.

That is, this character reading device 1 reads, for example, a multi-digit character recorded on a form being conveyed by optical scanning, converts it into an electrical signal, and compares the quantized character pattern with a standard character pattern. It is readable by character recognition.

The reading results of the character reading device 1 are supplied to the display device 2 according to this invention.

As shown in FIG. 2, this display device 2 has a plurality of numeric displays arranged in parallel, each consisting of seven display segments (a to g) arranged in a Japanese character shape and a decimal point display segment P. It is what it is.

The display device 2 decodes the reading result from the character reading device 1 using a well-known decoder circuit, and lights up each display segment of the numeric display according to the signals from the decoder circuit.

In other words, when the reading result is a correctly read number,
As shown in FIG. 3a, the numbers are displayed as they are.

For example, if the reading result is the correctly read alphabetic character "A-JJ", the decimal point "," will be lit and the number "1" will be displayed if it is the alphabetic character "A", as shown in the figure, and the alphabetical character rBJ will be displayed. , the decimal point "," lights up and the number "2" is displayed, and the following alphabetic characters rc-Jj similarly light up the decimal point "," and the number "2" is displayed.
3-9,0" is displayed.

When unreadability occurs, an unreadable display is performed as a number different from the above display, as shown in FIG.

Next, the operation in such a configuration will be explained.

For example, when a form is conveyed now, the characters on the form are read by the character reading device 1 as described above, and the reading result is supplied to the display device 2.

As a result, when the reading result is a number, the display device 2 displays only the number, and when the result is an alphabetic character rA-Jj, the decimal point lights up and the corresponding number "1~9°0" is displayed, making it unreadable. When this occurs, a number and an illegible display will be displayed.

In other words, the character you are trying to read is, for example, "123".
45AJ, and if this is read by the character reading device 1, the reading result will be "12345AJ, which is the fourth
It is displayed on the display device 2 as shown in Figure a.

Also, for example, if the reading result of another character is "98 US 765"
If it contains an unreadable character such as BJ, it is displayed on the display device 2 as shown in FIG.

As detailed above, according to this invention, when the reading result is correctly read, the character reading device displays a number without lighting up the decimal point, and the reading result is displayed as a correctly read alphabetic character, kana character, etc. At times, the decimal point lights up to display numbers, and when unreadability occurs, numbers are displayed that are different from the above display and are unreadable. It is possible to provide a display device that can be displayed with just a device and can reduce costs.

[Scope of utility model registration request] In the reading result display device of a character reading device that reads characters recorded on a recording medium, by using a numeric display with a decimal point as an indicator, the decimal point lights up when the reading result is a correctly read number. When the reading result is a correctly read alphabetic character or kana character, the decimal point lights up and the number is displayed, and when the reading result becomes unreadable, it is displayed as a number that is different from the above display and is unreadable.
