Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a reading output monitor printing method for printing reading results or processing results on a form so that it can be confirmed whether characters on the form have been reliably read. .

When reading characters on a form, if the read characters cannot be identified, a process such as rejection is performed, or if the document has a display function, it is displayed as unidentifiable and the characters are corrected using a keyboard, etc. and then input. things are being done.

However, if an incorrect identification is made, the identification result will be sent to the information processing device and processed.

Displaying the identification results of the read characters may be an option to eliminate this drawback, but if there are a large number of characters on the form, it is actually extremely difficult to check whether the characters on the form match the displayed content. It is difficult to

The present invention improves the reliability of reading characters on a form by printing identification characters that have been read and identified in the margins of the form after reading the characters on the form, and also printing content indicating areas that cannot be identified. It also aims to enable reliable character reading through re-input.

Examples will be described in detail below. FIG. 1 is a detailed explanatory diagram of the present invention, in which a form 1 is sent in the direction of the arrow by a feeding mechanism such as a roller 2. In FIG.

The characters on this form 1 are read by the sensor 3, and the read characters are identified by the character identification circuit 4.

The identification result is sent to the processing control circuit 5 and the printing control circuit 7, and the printing section 6 is operated by the output of the printing control circuit T to print identification characters on the form 1.

The results of the statistical calculations are sent from the processing control circuit 5 to the printing control circuit 7, and are printed on the form 1 by the printing section 6.

FIG. 2 shows an example of a form. When the sensor 3 reads the characters in the solid line frame of the line where the line mark 8 is detected, and the form 1 is sent to the printing unit 6, the characters are identified in the dotted line frame. The characters resulting from the identification in circuit 4 are printed.

In addition, if the number and unit price are written, the processing control circuit 5 can calculate the total amount, so the total price can be calculated by the printing unit 6.
printed by.

In addition, for rejects, errors, etc., for example, the character position can be printed by row and column, and when re-inputting, the character at the designated position can be corrected.

Furthermore, when reading characters on a form, a serial number is attached, so the printing unit 6 prints this serial number.

If the characters resulting from the reading and identification are printed above the characters on the form 1, as in the embodiment shown in Fig. 2, it is easy to compare the written characters with the identified characters, and it is possible to immediately identify incorrectly identified characters. can.

Note that it is of course possible to print identification characters below the written characters.

FIG. 3 is a schematic side view of the reading unit and printing unit, and FIG. 4 is a top view thereof, where MR and MP are motors, CDR and CDP are code plates, and DETR and DETP are detectors for detecting the passage of form 1. 3A indicates an optical scanning reading area, and 6A indicates a printing area.

Form 1 is sent in the direction of the arrow by motor MR, and when the leading edge of form 1 is detected by detector DETR, it is determined by counting pulses from code plate C3)H from that position to the position of the written character. The optical scanning reading is performed by the sensor 3 after stopping by detecting a row mark or by stopping by detecting a line mark.

Also, upon completion of reading, form 1 is sent in the direction of the arrow, and detector D
When the passage of form 1 is detected by ETP, code plate C
By counting the pulses from the DP, the form 1 is sent to the printing position by driving the motor MP, and the printing section 6 prints.

MEM is a memory having a capacity to store read character information for one sheet of paper, ALU is an arithmetic unit, REG is a register, PDV is a print drive circuit, and PR is a print mechanism unit.

In addition, R8T is the data of the distance from the edge of the form to the first line or the distance to the current stop line for stopping the characters written on the form at the reading position, and PST is the data of the distance from the edge of the form to the first line for stopping the characters at the printing position. Data on the distance to the first print position or distance from the current print line to the next print line, 1D is instruction data such as serial number and processing date, PRD is print data, fr,

The detection signal detr becomes 1''', and the code plate CD
The pulse signal cdr generated by H is applied to the counter RC1 via the AND circuit A1, and the counter RCI starts counting down.

When the preset contents of the counter RC1 become zero by down-counting, its output becomes 1'', the flip-flop FF1 is reset, and the driving of the motor MR is stopped.

Further, the flip-flop FF2 is set, and the set output causes the optical scanning reader SCN to scan and read the written characters on the form, and applies a read signal to the identification part RC.

The identification result of one line of read characters is stored in buffer register BF1.

Also, upon completion of optical scanning for one line, the flip-flop F F
2 f, i IJ is set, distance data R8T, that is, the distance to the next read line is preset in the counter RC1, and a feed command fr is given.

The feed of the form and the stop position control by the motor MR can also be performed by reading the line marks on the form.
In that case, when a line mark is detected by the line mark detection unit LMD, flip-flop FF1 is reset and flip-flop FF2 is set, the form is stopped at the line mark position, and optical scanning reading is performed.

When the form is further sent and detected by the detector 1) FTP, the detection symbol de tp becomes 1'' and the code plate CD
A pulse signal cdp generated by P is applied to the counter RC2 to start counting down.

When the preset contents become zero, the flip-flop FF3 is reset and the flip-flop FF4 is set, so the drive of the motor MP is stopped and the print data PRD set in the buffer register BF2 is added to the print drive circuit PDV. , is printed on the form by the printing mechanism unit PR.

In that case, the print data PRD follows the orientation of the identification result print command rp1 calculation result print command ap1 instruction data print command dp from the control unit, and when the identification result print command rp is given, the memo IJMEM The read data, that is, the identification character becomes print data.

Therefore, if applied to a character reading device that has a high probability of misreading or inability to identify, such as handwriting reading, the reliability of character reading can be significantly improved, and the situation in which misreading or inability to identify occurs can be significantly improved. Since it is easy to understand, it is very effective for practicing handwriting and for teaching.

Furthermore, when reading printed characters, deterioration in print quality can be immediately detected, so instructions can be given as to when to replace the printed characters or the ink ribbon.
