Description

  The present invention relates to a disc publisher for writing data to a disc such as a CD or a DVD, and a control method therefor.

  2. Description of the Related Art Conventionally, in order to prevent leakage of confidential data, a system and method for realizing high-security data management by unifying data output to an external recording medium writing device have been proposed. One example of the external recording medium writing apparatus is a disk publisher. The disk publisher writes data specified by the user to a disk such as a CD or DVD, and manages data by grasping creation, distribution and disposal of a data distribution disk. A disk on which data has been written is stored in a stacker in the disk publisher, and is ejected outside the apparatus at an appropriate time.

  Conventional disk publishers are equipped with a USB terminal, which is a dedicated terminal for connecting a numeric keypad keyboard for giving commands for controlling the apparatus.

  However, since a USB-compatible peripheral device can be connected to the USB terminal, it is possible to connect an external input device such as a normal keyboard in addition to the numeric keypad keyboard. The control command of the disk publisher is expressed by a combination of numbers by operating the numeric keypad, and this control command is allowed as an external input command. However, when an ordinary keyboard is connected, an unacceptable command may be input. When such a command is input, an unexpected setting may be performed from the outside.

  An object of the present invention is to eliminate an input of an unacceptable command.

  The present invention relates to a disk publisher comprising a drive for writing data to a disk and a stacker for storing the disk, a command table indicating allowed commands, an externally input command, and the command table. And a determining unit that determines to reject the input of a command when it is determined that a command not included in the command table is input.

  The present invention also provides a method for controlling a disk publisher comprising a drive for writing data to a disk and a stacker for storing the disk, and allows an externally input command and input. A step of collating with a command table indicating a command, and a step of performing a determination of rejecting an input of a command when it is determined that a command not included in the command table is input by the verification.

  According to the present invention, since command input other than commands preset in the command table is rejected, only correct command input can be accepted no matter what external input device is connected.

  In the present invention, the rejection of command input is notified. According to this configuration, it is possible to recognize that an input rejection command is an unacceptable command input by notifying when an unacceptable command is input. Note that the notification means includes the generation of a beep and lighting inside the publisher.

  FIG. 1 is a schematic configuration diagram showing a disk publisher according to an embodiment of the present invention. The disc publisher 100 is mainly composed of a drive 10, a printer tray 20, an autoloader 30, an internal control device 40, a blank disc stacker 50, a created disc stacker 60, a disc ejection stacker 70, and the like. The disk publisher 100 is connected to an operator personal computer (PC) 300, a creator personal computer (PC) 310, and the like via the network 200.

  The drive 10 performs a data writing operation or an erasing operation by overwriting data. The printer tray 20 is a tray for supplying a disk to a printer (not shown) that performs printing processing on the disk surface of the disk, and the disk on which data has been written is conveyed to the printer tray 20 by the autoloader 30. The disc for which the printing process has been completed is conveyed to various stackers described later by the autoloader 30. The autoloader 30 is a transport device for transporting a disk to each part in the disk publisher 100, and acquires, transports, and places a disk by each operation of vertical movement and rotation.

  The internal control device 40 is a control unit that performs overall control of the overall operation of the disk publisher 100, and creates a disk based on a control program preset in the disk publisher 100, an instruction from an external operator PC, and the like. Perform distribution operations and so on. The internal control device 40 stores a command table 41 that lists allowed control commands. Further, when a command is input from the outside, the command table 41 is collated, and the input command is a command. It includes a determination unit 42 that determines whether or not it is included in the table 41, and a notification unit 43 that notifies that the input is rejected because a command that is not in the command table 41 is input. When the input command is not included in the command table 41, the determination unit 42 rejects the input of the command and causes the notification unit 43 to perform notification. The notification unit 43 notifies the user that the input has been rejected by making a beep or turning on illumination (not shown) inside the disc publisher 100 main body.

  The blank disk stacker 50 is a stacker that supplies and accumulates blank disks for writing data. The blank disk 51 is conveyed to the drive 10 by the autoloader 30. The created disk stacker 60 is a stacker for temporarily accumulating disks on which data has been written by the drive 10, and the created disk 61 is stored in the stacker for a predetermined time. It is discharged to 70. The disc discharge stacker 70 is a stacker for distributing the created disc or the overwrite-erased disc 71 to the user. A disk that has been created or erased is directly conveyed from the drive 10 to the disk ejection stacker 70, or a disk that has been temporarily accumulated by the previously created disk stacker 60 is conveyed.

  The operator PC 300 is a terminal for remotely performing various settings for the disk publisher 100. It should be noted that the various settings are preferably configured such that only authorized operators can perform them according to the importance of the settings. On the other hand, the creator PC 310 is a terminal for instructing creation of a disk to be distributed. It is preferable that the external output of data is strictly managed by performing predetermined authentication or the like for the disc creator.

  FIG. 2 is a flowchart showing a control operation procedure of the disk publisher in the embodiment of the present invention. The disk publisher 100 waits for a command input from the outside via the operator PC 300, creator PC 310, or the like (step S101). When a command is input (Yes in step S101), the determination unit 42 of the internal control device 40 collates the command table 41 (step S102) and determines whether or not the input command is included in the command table. Is determined (step S103).

  FIG. 3 is a schematic diagram conceptually showing a configuration example of the command table stored in the disk publisher in the embodiment of the present invention. As shown in the figure, the command table is represented by ASCII codes.

  When the input command is not included in the command table 41 (No in Step S103), the determination unit 42 rejects the input (Step S104) and causes the notification unit 43 to notify that the input is rejected (Step S105). In the present embodiment, an input refusal is notified by the generation of a beep sound and / or lighting of the inside of the disc publisher 100 main body. The operator of the disk publisher can recognize that the input key code (command) is not permitted by the sound and lighting.

  On the other hand, when the input command is included in the command table 41 (Yes in step S103), the determination unit 42 accepts the command input (step S106) and executes an operation according to the command content such as start of disk creation. (Step S107).

  With the above control operation procedure, it is possible to accept only command inputs permitted in advance regardless of the external input device connected to the USB terminal. Therefore, it is possible to prevent an unexpected setting from the outside.

It is a schematic block diagram which shows the disk publisher in embodiment of this invention. It is a flowchart which shows the control operation procedure of the disk publisher in embodiment of this invention. It is a schematic diagram which shows notionally the structural example of the command table stored in the disk publisher in embodiment of this invention.
