[Detailed Description of the Invention] "Field of Industrial Application" The present invention allows data such as the payer, place of payment, drawer, place of draw, place of exchange, bank name, store name, account number, etc. to be recorded on promissory notes and checks. This relates to a printing device.

``Prior art'' Promissory notes, checks, etc. have the aforementioned six types of data printed on the paper] 2) A fixed number of sheets are given to the user, and the user writes in the amount and stamps them before issuing them. is common.

In addition, when displaying these data on paper, the symbol l in Figure 3 is used.
Ordinary (visually recognizable) characters such as
Numbers and symbols that are primarily machine readable, such as the number 2 (e.g., special characters made magnetically readable using MICRIC magnetic ink) or barcodes (such as those that can be read optically). symbol) is used in combination.

[Problem to be solved by the invention] By the way, in the case of promissory notes and checks, errors in the above-mentioned display data are absolutely unacceptable, so it is essential to check the printed content after printing. Regarding the above-mentioned MICRIC barcodes that cannot be recognized visually, it is necessary to read and check them with a dedicated reading device, which is a complicated task.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a data printing device for bills and checks that can reliably prevent errors in writing various symbols that are intended to be read by a machine.

"Means for Solving the Problems" In order to achieve the above object, the present invention provides necessary data on paper such as promissory notes and checks supplied from a paper supply unit by visually recognizable characters, figures, or a character printing section that prints the data as a code; a data printing section that prints the data as mechanically recognizable characters, figures, or codes; a reading section that reads the data printed by the data printing section; and the character printing section. paper feeding means for moving the paper in a section between the data printing section, the data printing section, and the reading section, and feeding the paper to a paper stacking section downstream of the data reading section;
It consists of a control section that controls the data printing section, the data reading section, and the paper feeding means, respectively, and the control section controls the data printing range on the paper on the condition that a printing end signal is input from the data printing section. The paper feeding means is operated in the reverse direction to move the leading edge of the data printing range to the "-" direction of the reading means, and the reading is performed while operating the paper feeding means in the forward direction on the condition that the leading edge of the data printing range reaches a predetermined position. Controlling the means to read data and the read data;
The data printing unit is configured to determine whether the printing data matches the printing data supplied to the data printing unit.

[Function j] With the above configuration, after the printing by the data printing means is completed, the paper is moved upstream of the reading means, and then the printed content of the data printing section can be read while passing through the reading means again. By comparing this printed content with the printed data of the data printing means, the data printed content can be confirmed.

"Example" Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

A reading magnetized head 32 and a reading head 33 are provided. That is, the magnetized head 32 magnetizes the printed portion of the M [CR character when the paper passes through the paper, and by reading the pattern of this magnetized portion with the RAD 33, magnetically reads the data corresponding to the M [CR character. is now possible. Note that reference numerals 34 and 35 are backup rollers that press the paper 10 against the heads 32 and 33, respectively.

Then, the paper that has passed through the reading rad 33 is moved by rollers 31 and sent to a downstream stacking section 36.

Next, a control mechanism for controlling the data printing section will be explained with reference to FIG.

Reference numeral 40 denotes a print data store section, and this print data store section 40 is, for example, a terminal device 4 attached to a printing device.

data about the position of the paper fed from
A forward rotation instruction is given to the conveyance motor 43 (for example, a motor with good positioning accuracy such as a stepping motor is used) for driving the paper drive mechanism consisting of the rollers 13, 14, etc. for a predetermined period of time. FW1- FW2
, or outputs a reverse rotation command RVS.

FWI, which is one of the forward rotation commands, is printed RJ+t
7 (generic term for character printing section and data printing section) 44 to control the printing mechanism 44 and operate the heads 19 and 29 along with normal rotation of the transport motor 43.
Characters that can be visually recognized by humans, or M I CR characters, etc. are printed at a predetermined position on the paper lO.

The other normal rotation command FW2 is supplied to a reading mechanism (general term for the magnetized head 32 and reading head 33), causes the reading mechanism 45 to read MICl<character 3, reads the read data, and stores it in the data storage. Part 4
It is designed to be sent to 5.

Furthermore, the data stored in the read data store section 45 is compared in a comparison section 46 to see if it matches the data stored in the print data store section 40. The comparison unit 46 outputs a normal signal or an abnormal signal based on the comparison result, and based on these signals, for example, an alarm device (not shown) is activated in response to the abnormal signal.

In the printing device configured as described above, MICR characters are confirmed as follows.

The paper 10 fed from the paper supply section 11 to the character printing section 15 is sequentially fed into the character printing section 15 and the data printing section 22, and is printed with predetermined character data (reference numeral l in FIG. 3).
Normal characters indicated by 2 and MICR characters indicated by 2) are printed. The above operation is performed by sequentially reading the print data stored in the print data store section 40 and sending it to the conveyance control section 40.
By supplying data about the position (timing of passage) of the paper 10 from the sensor 26, the transport control unit 42 outputs a forward rotation command FWI, and this forward rotation command FWI causes the transport motor 43 and This is done by controlling the printing mechanism 44.

Next, when the output of FWI from the transport control unit 42 is completed, that is, when the printing of predetermined characters l and 2 is completed, the transport control unit 42 issues a reverse rotation command RV to the transport motor 43.
S is supplied, the transport motor 43 reverses, and M I CR
The paper 10 located downstream of the printing mechanism 25 is moved in the opposite direction to a position where at least its leading edge returns upstream of the magnetization head 32.

Next, when it is determined that the paper 10 has moved in the reverse direction to a predetermined position, the transport control unit 42 issues a forward rotation command FW2.
is output. This FW2 is supplied to the conveyance motor 43 and causes the conveyance motor 43 to rotate once in the forward direction, and by this forward rotation, the paper 10 is fed into the reading mechanism 45 from the upstream side, and the pattern of the MICR character 2 on the surface of the paper lO is is read as magnetic data by the reading head 33 after being magnetized by the magnetizing head 32 .

After the read data is temporarily stored in the read data store section 46, it is read out sequentially, and the data stored in the print data store section 40 is also supplied to the comparator section 47, and the comparator section 47ζ compares both data. When compared, the success or failure of the MICR characters 2 on each sheet 10 can be determined each time printing is performed, based on the comparison result, that is, whether a normal signal or an abnormal signal is output from the comparing section 47.

In the above embodiment, a MICR printing mechanism was used as a printing means for mechanically readable data, but it is also possible to use a mechanism for printing optically readable codes such as barcodes. Of course, the present invention can also be applied.

In addition, in order to prevent 2m printing in which the printing operation is performed again on the paper 10 that has already been printed, a magnetized head and a reading head are provided between the rollers 13 and 14 of the paper supply section 11 to detect whether or not printing has been completed. You can also do this.

"Effects of the Invention" As is clear from the above description, according to the present invention, the print data for controlling the printing means for mechanically read data is compared with the data read from the paper after printing. However, the success or failure of data printing can be determined based on the result of this comparison, and therefore, the reliability of data printing on promissory notes, checks, etc. that are provided with data display fields such as MICR characters can be improved. In addition, since the necessary printing is done just before handing it over to the user, there is no need to store bills, checks, etc. for each user, and you can simply store the paper, making management easier. play.
