Description

The present invention relates to an image data printing method using an optical disk device.

〔Overview〕

According to the present invention, in an image data printing method using an optical disk device, a request from a print request device is classified into optical disk units, data read from the optical disk is temporarily stored, and the stored contents are provided to the printing device in the order of request. The present invention is intended to reduce the frequency of changing optical disks on an optical disk device.

[Conventional technology]

Conventionally, in an image data printing method using a collective optical disk device, an optical disk requested to be searched by a print request device is set in a drive mechanism each time and image data is read.

[Problems to be solved by the invention]

In such a conventional method, it is necessary to change the optical disk every time a print request is made from the print request device. Therefore, when there is a print request from a plurality of print request devices, the change of the optical disk frequently occurs, There is a disadvantage that the system efficiency is extremely reduced.

An object of the present invention is to provide an image data printing method in which the frequency of changing optical disks in a collective optical disk device is relatively low.

[Means for solving the problem]

The present invention relates to a collective optical disk device that reads image data from a mounted optical disk, a print request device that issues a print request related to desired image data, and a printing device that prints an image related to image data. In the printing method, a control device having an optical disk reading unit for classifying a print request coming from the print request device into optical disk units and reading image data from an optical disk on the collective optical disk device according to the classification, and the optical disk reading unit And an auxiliary storage device for temporarily storing the image data read by the control unit. The control device further reads the image data stored in the auxiliary storage device in the order of arrival of the print request, and transfers the image data to the printing device. A transfer unit is provided.

[Action]

Upon receiving a print request from the print request device, the print request is sorted for each optical disk, and the image data read from the collective optical disk device is transferred to the auxiliary storage device. Next, the print image data is transferred from the auxiliary storage device to the printing device in request units.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment. 2 and 3 show an example of print request information, and FIG. 4 shows a result of sorting the print request information.

In this embodiment, as shown in FIG. 1, a collective optical disk device 1, a control device 2 including a print request receiving unit 21, an optical disk reading unit 22, and a print image data transfer unit 23, an auxiliary storage device 3, Requesting devices 4 and 5 and printing device 6
And a local area network 7. That is, in this embodiment, the collective optical disk device 1 reads image data from the mounted optical disk, the print request devices 4 and 5 issue a print request related to desired image data, and the printing device prints an image related to image data. A control device 2 having an apparatus 6 and an optical disk reading unit 22 for classifying print requests received from the print request apparatuses 4 and 5 into optical disk units and reading image data from optical disks on the collective optical disk apparatus 1 according to the classification; The control device 2 further includes an auxiliary storage device 3 for temporarily storing image data read by the optical disk reading section. The control device 2 further reads the image data stored in the auxiliary storage device 3 in the order of arrival of the print request, and Print image data transfer unit 23
Is provided.

Next, the operation of this embodiment will be described. Here, FIG. 2 and FIG.
The operation when the print request shown in FIG.

This print request is received by the print request receiving unit 21 of the control device 2, and is notified to the optical disk reading unit 22. The optical disk reading unit 22 sorts the print requests into optical disk units as shown in FIG. 4, sequentially reads the print image data from the optical disk, and transfers the print image data to the auxiliary storage device 3. As a result of the sorting, the number of times of changing the optical disk is 4 for 6 times.
Times have decreased. When the transfer of all print image data to the auxiliary storage device 3 is completed, the image data is read from the auxiliary storage device 3 in the order of the print requests shown in FIGS.
The data is transferred to the printing device 6 via the local area network 7.

The same procedure is followed when the number of print requesting devices is greater than in this embodiment. The greater the number of printing requesting devices, the greater the possibility of reducing the number of times of changing optical disks.

〔The invention's effect〕

The present invention, as described above, has the effect of minimizing the number of replacements of a collective optical disc and greatly improving system efficiency by sorting print requests in optical disc units.
