Description

Detailed Description of the Invention <Industrial Application Field> The present invention is directed to MICR, which prints and reads characters using special ink containing magnetic materials.
( Magnetic Ink Character Recognition ;
The present invention relates to a magnetic ink character recognition (magnetic ink character recognition) system.

<Conventional technology> The MICR system is based on the American Bankers Association (ABA)
It was developed by the company for the purpose of mechanizing and increasing the efficiency of administrative processing such as checks and bills. A dot printer or line printer prints codes, symbols, amounts, etc. in a special character shape (called MICR printed characters) using special ink containing magnetic material on a maximum of 70 characters, which is then read by a magnetic ink character reader. (magnetic ink character reader)
The characters are read by sliding a magnetic head over the magnetic ink characters, and the characters are recognized by comparing the characteristic analog waveform of each character with a standard pattern.Furthermore, the characters are classified using a magnetic sorter (sorter). I'm starting to do that.

At a bank, when a customer brings a check to a counter, certain data such as the amount is written on the check using magnetic ink in a special typeface (an example of MICR printed characters) as shown in Figure 4. It is printed by

The card that prints the MICR characters has an account number, etc., and a check digit is usually added to this account number. This check digit algorithm is stored in a preset or the like.

<Problems to be Solved by the Invention> However, if it becomes necessary to change the check digit algorithm during the operation of printing MICR characters, the algorithm can be changed using the preset means described above. I had to.

Further, this presetting is usually performed by a manager, which requires calling the operator/manager, which takes time.Furthermore, the presetting operation is also very troublesome and time consuming.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a printing device for MICR printed characters in which the check digit algorithm can be easily changed.

<Means for Solving the Problems> In order to achieve the above object, the MICR printing character printing device of the present invention includes an input means for inputting arbitrary data and a check mark at an arbitrary position of the inputted content. a printing means for printing characters with a special shape using magnetic ink, and a storage means for storing a plurality of types of algorithms for generating check digits for input data;
The printing apparatus includes algorithm determining means for selecting and executing any one of the stored algorithms, and control means for generating data to be printed according to the selected algorithm.

<Operation> When inputting data, select an arbitrary algorithm, and based on the selected algorithm,
A check digit is added to the input data and MICR print characters are printed.

<Examples> The present invention will be specifically described below with reference to illustrated examples.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, in which 10 is an input means, 15 is an algorithm determining means, 20 is a storage means, 30 is a control means, and 40 is a printing means. Also, s and d are
3 shows the flow of command signals and data, respectively.

The input means 10 is for specifying fields to be printed, inputting account numbers, amounts, etc., and uses a keyboard.

As shown in FIG. 3, the algorithm determining means 15 extracts an algorithm from a plurality of types of algorithms stored in advance in the algorithm storage section 21 of the storage means 20 by the preset means 11, and selects the algorithm from the selection means 17. An arbitrary one is selected, and a command is sent to the control means 30 together with the printing conditions of the corresponding encode field to add a check digit.

The storage means 20 includes the algorithm storage section 21
In addition, it consists of a storage section 22 for encode field printing conditions and storage sections for various types of data.

The control means 30 controls the encoding operation by calculating check digits, generating encoded data, etc. in response to commands from the input means 10, the algorithm determining means 15, etc.

The printing means 40 prints MICR print characters using magnetic ink, and a printer is used.

Note that the algorithm determining means 15, storage means 20, and control means 30 may be integrated into one by using a one-chip microcomputer.

With the above configuration, the apparatus of the present invention performs encoding processing by performing operations as shown in FIG. In other words, the encode field specified by the field key of the input means is specified, the printing conditions of the encode field are read out from the storage means, the data is taken in from the input means, and the algorithm determining means of the check digit is used to select an arbitrary algorithm. is selected, a check digit is calculated, encoded data is generated, and the printing means performs an encoding operation, that is, prints MICR print characters.

Here, an example of the check date is shown below.
When the input data is 85170669 and the position of the check digit is the 8th digit, the algorithm doubles the number in the odd number digits, multiplies the number in the even number digits by 1, and adds them. Determine the number of check digits so that the total is 70. In this case, the following calculation is performed to calculate the number of check digits.

70-69=1 Therefore, since the check digit is 1, 815170669 is obtained as encoded data as a result of calculating the check digit.

It should be noted that this check digit algorithm may be selected as appropriate, and the more types are stored, the wider the selection range becomes.

<Effects of the Invention> As is clear from the above description of the embodiments, according to the present invention, a large number of check digit algorithms are stored and can be arbitrarily selected by the algorithm determining means. As a result, the check digit algorithm can be easily changed, there is no need to call a manager, etc., and office efficiency can be improved.
