Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic check writer, and more particularly, to an automatic check writer that reads a bar coded and recorded withdrawal amount and reliably prints the read withdrawal amount in the withdrawal amount entry column in increments. Regarding automatic check writers.

[Technical background of the invention and its problems] Today, bills, etc. are increasingly issued by computers. Issuance of bills, etc., performed by this computer is performed by printing the data-managed contents such as the draw date, amount drawn, payment date, payee, etc. onto continuous bill paper.

However, in order to prevent tampering, it is preferable to print only the amount to be withdrawn using a conventional check writer, so-called increment printing (printing divided by fine diagonal increments). Since this increment printing is not possible with normal printer printing, conventional printing has been carried out as follows.

The other contents except the withdrawal amount are printed using a normal printer, and only the withdrawal amount is printed using an ordinary check writer.

Data on bill issuance details is obtained from a floppy disk or online from a general-purpose computer, and a bill issuance machine is used that issues bills based on this data.

If the above method is used, there are disadvantages in that it is time-consuming and that errors are likely to occur because the operation is performed manually.

Furthermore, in the case of performing the above method, the issuing machine must have two printing mechanisms for incremental printing and normal printing, which inconveniences that the device configuration becomes large-scale and the device becomes expensive.

On the other hand, a printer with a barcode reading mechanism that reads and prints barcodes was proposed in Japanese Patent Laid-Open No. 57-6974, and an electronic check writer that automatically prints in increments on checks etc. by inputting information was proposed. Each of these is proposed in Japanese Patent Application Laid-Open No. 56-46757.

By the way, even if the above-mentioned checkwriter is added with the function of reading and printing barcodes from a printer with a barcode printing mechanism, and even if the barcode is read and inputted as information into an electronic checkwriter, the checkwriter will not be able to print it out. Numbers that are printed in increments can be used as money or as evidence of payment of money, so it is absolutely impossible to make a mistake, so the input of that information and the specific increments must match exactly. If there is even the slightest doubt about the reliability of a product, it becomes a major problem.
It was clear that there were concerns about the reliability of the simple addition, since it would be transmitted as a signal as is.

[Object of the Invention] The present invention solves the above-mentioned inconvenience and improves the reliability of the correspondence between the read signal and the printed digits by using an automatic check writer as an issuing device for bills, checks, etc., which does not cause errors in printing the amount to be withdrawn. The purpose is to provide sufficient products and at low cost.

[Summary of the Invention] In order to achieve the above object, the present invention comprises a paper transport path disposed within a machine frame, a printing mechanism provided in contact with the paper transport path, and a printing mechanism disposed at the entrance of the paper transport path. A reading sensor that detects the insertion of paper and optically reads the withdrawal amount recorded on the inserted paper, and a control mechanism that controls a printing mechanism to print the withdrawal amount data read by this reading sensor. The paper conveyance path is composed of a paper guide plate, a conveyance roller, and a pinch roller that contacts the conveyance roller and rotates oppositely, and the printing mechanism has a printing plate for marking in increments on the circumference and is rotated by a pulse motor. The control mechanism rotates the conveyance roller in response to a paper detection signal from a reading sensor, and swings out by the movement of the paper conveyance. The amount data is continued, the printing mechanism is operated based on this withdrawal amount data, and the rotation of the conveying roller is stopped when printing is completed. The present invention is characterized in that an optical mark for specifying the plate is provided and the optical mark is formed so as to be detectable by a mark detection sensor.
