Abstract

PURPOSE:To eliminate a retraction mechanism of a tension roller, and to reduce the fitting space, shorten the process time, and lower the cost by providing a booklet conveying means which is driven by a driving source taken from a conveyance system. CONSTITUTION:A bankbook 3 is conveyed by feed rollers 11 and 12, pressure rollers 13 and 14, a setting roller 8 which transmits the turning force of the feed roller 12 by a timing belt 9, and the tension roller 6. Once a transmission type sensor 4 detects the bankbook 3, a bar code read part 5 is triggered in response to the detection to start reading a page bar code out of the bankbook 3, which is conveyed without stopping even after the detection (light shielding) by the transmission type sensor 4. Further, when the transmission type sensor 4 comes into a light passing state after the bankbook 3 passes by the transmission type sensor 4, the read of the page bar code on the bankbook 3 is ended. Namely, the setting roller 8 is driven to rotate at this time, thereby serving as part of the conveyance part.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bar code reading mechanism for a booklet printing apparatus.

[0002]

2. Description of the Related Art FIG. 2 is a diagram showing the construction of a printing apparatus for booklets such as passbooks. Referring to FIG. 2, in this booklet printing apparatus for passbooks, etc., when the passbook is sucked from the suction / discharge port 23,
The barcode reading unit A50 reads the page barcode of the passbook. Next, the magnetic recording / reproducing unit 24 reads the magnetic data (account number, etc.) on the back cover of the passbook. Next, passbook is print head 2
It is conveyed to 1 and printed. When the next page of the passbook is printed, the passbook is conveyed to the page turning unit 22, turned over, and returned to the barcode reading unit B51 for confirmation.
The page bar code can be read. Again, passbook is print head 2
It is conveyed to 1 and printing is performed. Finally, the passbook is returned to the magnetic recording / reproducing unit 24, data is written therein, and the passbook is ejected from the ejection port 23.

3A to 3C are state diagrams in the vicinity of the conventional bar code reading section 5. In FIG. 3A, the passbook 3 is conveyed by the feed rollers 11 and 12 and the pressure rollers 13 and 14. When the transmissive sensor 4 detects the passbook 3 and enters a light-shielding state, the passbook 3 is temporarily stopped. Next, as shown in FIG. 3B, the general-purpose solenoid 15 attracts and the tension roller 6 is raised by the link mechanism and pressed against the setting roller 8. Then, as shown in FIG. 3C, the passbook 3 is conveyed again, and the barcode reading unit 5 starts reading. Passbook 3
When the light passes through the transmissive sensor 4 and becomes a light-transmitting state, the reading ends. The general-purpose solenoid 15 is restored and the tension roller 6 is lowered to complete the operation. In this conventional example, since the setting roller 8 and the tension roller 6 do not have a drive source, if the tension roller 6 is still raised, a jam will occur when a slip or the like having a weak waist is conveyed. Therefore, such a retraction mechanism is necessary.

[0004]

Since this conventional bar code reading mechanism requires a retraction mechanism for the tension roller, it requires a large mounting space and operating time (processing time). It is also a factor of high cost.

[0005]

A bar code reading mechanism of a booklet printing apparatus according to the present invention comprises a booklet conveying means which incorporates a drive source from a conveying system and a bar code reading device which reads each page bar code in the booklet. And means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 2 is a diagram showing a configuration of a booklet printing apparatus such as a passbook. Referring to FIG. 2, in this passbook or other booklet printing apparatus, when the passbook is sucked through the suction / discharge port 23, the barcode reading unit A50 reads the page barcode of the passbook. Next, the magnetic recording / reproducing unit 24 reads the magnetic data (account number, etc.) on the back cover of the passbook. Next, the passbook is conveyed to the print head 21 and printed. When the next page of the passbook is printed, the passbook is conveyed to the page turning unit 22, turned over, returned to the barcode reading unit B51 for confirmation, and the page barcode is read. Again, the passbook is conveyed to the print head 21 and printed. Finally, the passbook is returned to the magnetic recording / reproducing unit 24, data is written therein, and the passbook is ejected from the ejection port 23.

FIG. 1 is a block diagram of an embodiment of the present invention.
Referring to FIG. 1, the bar code reading mechanism of this booklet printing apparatus includes feed rollers 11 and 12, pressure rollers 13 and 14, a setting roller 8 for transmitting a rotational force of the feed roller 12 by a timing belt 9, The passbook 3 is conveyed by the tension roller 6. When the transmissive sensor 4 detects the passbook 3, the barcode reading unit 5 starts reading the page barcode of the passbook 3 by using this as a trigger. The passbook 3 is conveyed without stopping even after the detection (light shielding) by the transmissive sensor 4. When the passbook 3 passes through the transmissive sensor 4 and the transmissive sensor 4 enters the light-transmitting state, the reading of the page barcode of the passbook 3 is completed.

In this embodiment, since the setting roller 8 is driven to rotate and becomes a part of the conveying portion, it does not cause a jam and the retraction mechanism can be eliminated. This saves space, shortens processing time, and reduces costs.

[0009]

As described above, according to the present invention,
By providing the booklet conveying means that takes in the drive source from the conveying system, the tension roller retraction mechanism is eliminated, so that the installation space, processing time and cost can be reduced.
