JPH09330375A - Bar code reader - Google Patents

Abstract

PROBLEM TO BE SOLVED: To distinguish between a read bar code and an unread bar code in a short time, by providing a marking mechanism at a bar code read opening and adding a check mark by the bar code which is already read. SOLUTION: At the time of a marking request command, the driver software 4 for the bar code reader sends a marking request command, which is stored in a bar code reader I/O buffer 5. A bar code reader control program 6 confirms the command. A circuit 7 for request command analysis judges which of a bar code read request command and a marking request command this command is and a marking control program 11 is executed to place a driving control part 12 for a marking pen in operation, and a driving motor part 13 and the marking pen 2 are driven for marking.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a reading port of a bar code reading device of a device connected to a personal computer or the like, and a control method by a control program that controls reading of a bar code.

[0002]

2. Description of the Related Art In the prior art, when a large number of bar codes are read, the read bar code and the unread bar code are confirmed by pairing the bar code data output by the driver with the display device and the printer. I had to confirm with 1. Further, since the barcode cannot be identified even if it is read, it takes a lot of time to search for an unread barcode.

[0003]

In the prior art, it was not possible to easily identify whether a bar code was read or unread, so that it took a lot of time to search for an unread bar code.

An object of the present invention is to provide a system in which a read / unread bar code can be distinguished in a short time by adding a check mark next to the read bar code.

Still another object of the present invention is to provide a control program for adding a check mark to a read bar code.

[0006]

According to the present invention, there is provided a bar code reading apparatus having a bar code reading section and a marking mechanism section.

Further, according to the present invention, there is provided a control program which is provided with a buffer for marking inside the bar code reader and which accesses the buffer to control the marking system.

According to the present invention, the bar code reading section and the marking mechanism section can perform marking on the side of the bar code for confirming that the bar code has been read.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of the bar code reading apparatus.

FIG. 2 shows a control diagram of the bar code reading apparatus.

FIG. 3 is a flow chart showing the control of the bar code reading apparatus.

In order to read a bar code on a personal computer or the like, the bar code reading driver software 4 incorporated in the personal computer is activated and the request command is stored in the I / O buffer 5 in the bar code reading device. .
The bar code reader control program 6 identifies and confirms the command. Next, the request command analysis circuit 7 determines whether this command is a barcode read request command or a marking request command.

In the case of the bar code reading request command, the reading control program 8 is executed and the optical sensor control unit 10 operates to read the barcode by the optical sensor 1. The read data is stored in the reading buffer 9 by the optical sensor control unit 10 and sent to the I / O buffer 5. The I / O buffer 5 returns the read data to the bar code reading driver software 4, and the bar code reading is completed.

In the case of a marking request command, a marking request command is sent from the bar code reading driver software 4 and the request command is stored in the bar code reading device I / O buffer 5. The bar code reader control program 6 recognizes and confirms the command. The request command analysis circuit 7 determines whether this command is a bar code reading request command or a marking request command, the marking control program 11 is executed, the marking pen drive control unit 12 operates, and the motor unit 13 and the marking pen 2 are driven. And mark. After the marking is completed, an end code is returned to the bar code reading device I / O buffer 5, and the I / O buffer 5 returns a marking end command to the bar code reading driver software 4 to complete the marking process.

[0016]

According to the present invention, a check mark is added beside a bar code that has already been read, and it is extremely convenient to visually check a bar code that has not been input when a large amount of data is input.
