Abstract

PURPOSE:To improve the accuracy of the bar code reading of a sensor by forcibly turning the distance between the sensor and the surface of the bar code to be constant. CONSTITUTION:By pushing up a platen 9, etc., the distance between a sensor 5 and the surface of a bar code 6 is turned to be constant. Namely, the platen 9 is clamped, the passbook 2 is pushed up to be stuck to a form guide 10, and the bar code sensor 5 mounted on a printing carrier 4 performs scanning while carrying the printing carrier 4 by a stepping motor driving. By this operation, the information of the passbook bar code is accurately transmitted to the main body of a reader. Therefore, the malfunction is prevented even when the thickness of media varies according to pages. Thus, the accuracy of reading can be improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a mechanism for keeping the distance between a sensor and a barcode surface constant in an optical sensor reading device of a passbook handling device and a reading method thereof. .

[Conventional technology]

The mechanism for keeping the distance between the barcode sensor and the barcode printed surface of the medium constant is to constantly press the medium against the barcode sensor with a weak spring, as described in Japanese Patent Laid-Open No. 59-106076.

[Problem to be solved by the invention]

In the above conventional technology, as a means to keep the medium and the reading sensor at the same distance, a weak spring is used to push up the medium at 9S'. The difference in thickness could not be fully absorbed, and it was necessary to consider the balance between the conflicting forces of media conveyance resistance and media push-up force.

An object of the present invention is to improve reading reliability by always keeping the distance between the reading sensor and the medium constant even when the media have different thicknesses.

[Means to solve the problem]

In order to achieve the above object, the barcode reading means is configured to keep the distance between the sensor and the barcode surface constant by pushing up a platen or the like and pushing it back against a stopper.

[Effect]

The medium pushing up device holds the conveyed medium between the paper guide and the medium 1 lowering mechanism. As a result, even if the thickness of the medium differs depending on the page, the distance between the medium and the sensor remains constant and no malfunction occurs.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 2 shows a schematic diagram of the mechanism of a passbook printer for a bank terminal, which is an example of the passbook handling device of the present invention. The passbook printer inserts the passbook 2 through the suction/discharge port 1, and presses rollers 3a' to 3b facing conveyance rollers 3a to 3b.
' to transport it to a certain position and stop. The barcode sensor 5 mounted on the print carrier 4 reads the barcode 6 information of the passbook 2, and after completing the predetermined operation, the passbook 2 is conveyed to a certain position and the print head 7 performs the bookkeeping printing process, and then the conveyance roller 3a - 3b and is of the type that is inhaled and discharged into one unit.

The present invention is associated with a barcode reading mechanism,
Details will be explained below with reference to FIG.

In FIG. 3, the bankbook 2 is controlled to stop when it is conveyed to a certain fixed position by conveyance rollers 3a to 3b. Passbook 2 has different thicknesses depending on its pages (Figure 3 a shows the large thickness of the passbook.

b shows the case where the passbook thickness is small. ), Also, paper surface distance variation occurs depending on the height of the conveyance path 8, but in order to eliminate this variation, the platen mechanism of the passbook printer is used, and the platen 9 is clamped so that the passbook @2 is brought into close contact with the paper guide 10. Push up. Then, the barcode sensor 5 mounted on the print carrier 4 drives the print carrier 4 by a stepping motor.]
1J [fl Convey and scan by movement. This operation accurately transmits the information on the passbook barcode 1-6 to the main body of the reading device.

According to this embodiment, in the process of barcode reading operation, by keeping the distance between the sensor and the barcode surface constant, the reading performance is improved and the medium is not damaged. There is.

〔Effect of the invention〕

According to the present invention, by forcing the distance between the sensor and the barcode surface to be constant, there is an effect of improving the bar code reading accuracy of the sensor.

Further, it is possible to provide a barcode reading device with high reliability in reading barcodes.
