Abstract

PROBLEM TO BE SOLVED: To easily identify an optical disk without an error by transferring an order number to a production control system, obtaining a corresponding disk number and discriminating whether the recorded disk number and the disk number read from the bar code printed on the disk are agreed to each other or not. SOLUTION: A control section 11 requests a production control system 8 to read the bar code of an order card with a bar code scanner 7 and to return a corresponding disk number and a screen block number. The section 11 records these numbers in a code recording section 10 and asks the scanner 7 and a bar code reader 6 to read each bar code printed on the screen block of the disk. The section 11 then compares each bar code read and the screen block number and the disk number recorded in the section 10, discriminates whether they are agreed to each other or not and identifies the disk. Thus, the disk, which is exactly ordered, is easily identified.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical disk identification device for identifying whether an optical disk matches a target order.

[0002]

2. Description of the Related Art Many optical disk manufacturing processes include a process of identifying an optical disk. In a conventional optical disk identification device for identifying an optical disk, an operator manually inputs and records a disk number based on an order in the optical disk identification device, reads a bar code stamped on the optical disk, and reads a bar code of the read bar code. The discrimination is made by determining whether the disc number matches the recorded disc number.

[0003]

As described above, in the conventional optical disk identification device, the operator manually inputs the disk number. For this reason, in the case of high-mix low-volume production, the disk number must be frequently input, and the number of operations is increased, and the disk number may be erroneously input.

[0004] It is an object of the present invention to provide an improved optical disc identification device so that an optical disc can be easily identified.

[0005]

According to a first aspect of the present invention, there is provided an order number transferring means for transferring an order number to a production management system, and a production method based on the transfer of the order number. A code recording unit that records the disc number returned from the management system, a barcode reader that reads a barcode imprinted on the optical disc, a disc number that is read by the barcode reader, and the code number that is recorded in the code recording unit. Determining means for determining whether or not the disc numbers match, and discriminating means for distinguishing the optical disc based on the result of the determination by the determining means.

[0006] The order number is transferred to the production management system, the production management system returns the disk number corresponding to the order number, records the disk number, and reads the disk number read from the bar code stamped on the optical disk and the recorded disk. Since the optical disk is identified based on whether or not the numbers match, it is possible to easily identify the optical disk as ordered without errors.

In the invention of claim 2, the order number transferred to the production management system by the order number transfer means is data obtained by reading a barcode written on an order card with a barcode scanner. Since the order number to be transferred to the production management system is transferred by reading the barcode written on the order card with a barcode scanner, the order number can be easily transferred without error.

In the invention according to claim 3, the order number is transferred to the production management system and the disk number is returned from the production management system by radio. Since the transfer of the order number to the production system and the return of the disk number from the production system are performed wirelessly,
A data transfer path between the production system and the optical disc identification device can be easily formed.

[0012] After the optical disk is formed by a molding machine, sputtering and coating of a protective film are performed.
As shown in FIG. 5, a bar code for recording the disc number is stamped inside the data recording area of the disc. The production management system 8 is a system for managing the production of optical discs, and manages the number of products, delivery date, printing screen version, manufacturing machine number, progress status, etc. for each product type. For example, when printing on an optical disc by a printing device, the optical disc number is used. An order card is recorded in which a bar code as shown in FIG. 4 is recorded in addition to the screen plate number to be printed, the number of sheets, and the like.

As shown in FIG. 4, a bar code is also recorded on a screen plate as an original to be printed by the printing apparatus 3. Next, the operation of the embodiment will be described with reference to FIGS. The operation is started by inputting a set command from the input unit 12 to perform initialization.

In step S1, the operator first reads the bar code of the order card described with reference to FIG. In step S2, the control unit 11
Transfers the barcode data of the order card read in step S1 to the production management system 8 via the I / O 14.

In step S3, the production management system 8
Returns the disk number and screen version number corresponding to the barcode data transferred in step S2, and proceeds to step S4 to record the returned disk number and screen version number in the code recording unit 10.

In step S5, the operator causes the bar code scanner 7 to read the screen version of the bar code.
In step S6, the control unit 11 compares the screen version barcode data read in step S5 with the screen version number recorded in the code recording unit 10,
It is determined whether or not they match, and if they do not match, step S
Then, the process proceeds to step S7, and the display unit 9 displays a mismatch, and ends the process.

If they match, the process proceeds to step S8, and the operator sets a screen plate on the printing device 3. When the setting of the screen plate is completed and the operator inputs the screen plate setting completion from the input unit 12, step S9 is started.

In step S9, the controller 11 instructs the transporter 1 to transport the optical disk to the reading device. In step S10, the control unit 11 instructs the barcode reader 6 to read the barcode engraved on the optical disk, and proceeds to step S11 to read the read barcode data and the diskcode recorded in the code recording unit 10. It is determined whether or not the numbers match, and the determination result is Y
In the case of ES, the process proceeds to step S14, and in the case of NO, the process proceeds to step S12.

In step S12, the display unit 9 displays the presence of a mismatched disk.
