DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device in which a disk serving as a recording medium is mounted on a tray provided to be able to enter and leave the apparatus main body and the disk is loaded into the apparatus main body. This makes it possible to set the disk device to an inoperable state by a simple operation.

[0002]

2. Description of the Related Art Conventionally, in a personal computer having a built-in disk device, for example, in order to substantially conceal a disk in which contents harmful to young people are recorded,
A key or computer whose power cannot be turned on by a key, or a character or a figure registered in advance as password data, unless a character or figure input from an input device matches the registered password data. Some are configured so that the computer does not operate normally.

[0003]

However, in the above-described configuration, the one that locks the key is easy to lose a small key, cares about its management, and when unlocked, it is difficult to store it. was there. Further, the method of using the password data has a problem that the password data is forgotten or known to others.

Further, in the conventional configuration, the entire computer including the disk device becomes inoperable. For example, if there is a disk which the user does not want to show, if only the disk device is inoperable, the computer will not operate. For some purposes, it can be convenient for others to use freely.

[0005]

In order to solve the above-mentioned problems, a disk device having a tray according to the present invention mounts a disk, which is a recording medium, on a tray provided so as to be capable of entering and leaving the device body. In the disk device, the tray is detachably attached to the apparatus main body, a unique code is formed on the tray, and the apparatus main body is provided with a recognition unit for recognizing the code, and the code recognized from the recognition unit is provided. Only when matches the predetermined code,
The disc is configured to be playable.

According to this configuration, the tray itself is a substantial key, and when the disk device is not locked in a non-uniform state, the tray is used as a disk device, so there is no risk of loss. Even when it is locked and removed, it is relatively large, so that it can be easily stored.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention according to claim 1 of the present invention is directed to a disk device in which a disk serving as a recording medium is mounted on a tray provided so as to be able to be inserted into and removed from the apparatus main body, and the tray is attached and detached. Attached to the apparatus main body as possible, a unique code is formed on the tray, and the apparatus main body is provided with a recognition unit for recognizing the code, and the code read from the recognition unit matches a predetermined code. A disk device having a tray characterized in that the disk can be reproduced only when the disk device is operated. According to this configuration, the tray itself serves as a substantial key, and the disk device is operated in an inactive state. When not locked, it is used as a disk device, so there is no danger of loss.When it is locked and removed, it is relatively large. Storage management is made easier.

According to the invention described in claim 2 of the present invention, the code can be easily read by using reading means using optics as the recognition means.

According to a third aspect of the present invention, the apparatus main body is connected to a computer, and when the tray is removed from the apparatus after a predetermined operation, the reading means is provided. 2. The disk device having a tray according to claim 1, wherein the computer is configured to be operable only when a code read from the computer matches a predetermined code. The computer can be operated, but it is convenient to select the case where only the disk device is made inoperable and the case where the computer is also set to be inoperable by a simple operation.

(Embodiment) Hereinafter, a first aspect of the present invention will be described.
An embodiment of the invention described in claim 3 will be described with reference to the drawings. FIG. 1 shows an overview of a computer having a built-in disk device for loading a disk by a tray. A disk device 12 having a tray 13 is built in the front of a computer 11.

When the ejection switch 14 is pressed, the tray 13 is ejected as shown in FIG. In this embodiment, the tray 21 is further pulled out from this state by hand, so that the tray can be taken out from the disk device 12 by itself as shown in FIG.

As shown in FIG. 3, an ID code 33 unique to each tray is provided on the back surface 31 of the tray 13. An auxiliary power switch 15 is provided on the front surface of the tray 13. When the auxiliary power switch 15 is pressed after the tray 13 is turned on to a regular position, the switch 32 formed on the rear surface of the tray 13 rotates. A computer auxiliary switch (not shown) provided on the surface facing the back of the tray is turned off, and is turned on when pressed again.

Next, this operation will be described. In the case of using a disk device, the disk is placed on the tray 13, and when the tray 13 is inserted to a regular position, the ID code 33 is optically read by a reading device provided on the surface facing the rear surface of the tray. When the ID code matches the ID code registered in advance, the disk device performs a normal operation.

Therefore, if the tray 13 is removed,
Even if another tray is inserted, the disk device does not perform a normal operation. If the computer auxiliary switch is turned off by operating the power auxiliary switch 15 before removing the tray, the computer does not operate normally even if the main power switch normally used for the computer is turned on. That is, the computer can be set to the unusable state. FIG. 4 is a flowchart showing these operations. When the main power of the computer is turned on (S1), first, it is checked whether or not the tray is inserted in a proper position in the disk device (S2). If it is inserted, the ID code formed on the back of the tray is read, and it is checked whether the ID code matches the registered normal ID code (S3). All the devices can be operated normally (S4). If not, disable all computers and disk units
(S4). If the tray is not inserted, it is checked whether the computer auxiliary switch is ON or OFF (S5). If the computer auxiliary switch is ON, the computer itself is brought into a normal operable state except for the disk device (S6). If the computer auxiliary switch is in the OFF state, all of the computer and the disk device are disabled (S7).
FIG. 5 is a flowchart in the case where the tray is removed from the disk device in order to lock the disk device in an inoperable state. First, when the tray discharge switch 14 is pressed to discharge the tray (S2), it is checked whether the computer auxiliary switch is turned ON or OFF by operating the power auxiliary switch 15 (S3). If the computer auxiliary switch is in the ON state, the tray is ejected as usual (S4), and the tray can be manually extracted from the ejected state. Therefore, in this case, the disk device is inoperable, but the computer is operable. On the other hand, if the computer auxiliary switch is in the OFF state in S4, it is determined that the computer does not operate normally after the tray is removed.
A message to be communicated to the user is displayed (S5), and confirmation of the user is requested. Only when the confirmation is obtained (S6), the tray is ejected. When the confirmation is not obtained, the tray is not ejected (S6).
8).

[0015]

As described above, according to the present invention, an ID code unique to the disk device is provided on the tray of the disk device.
The disk device does not operate unless the ID code of the device and the tray coincide with each other. Therefore, by removing the tray from the disk device main body, the disk device is rendered inoperable and substantial disk media can be concealed. The tray itself is the key, and it is used as a disk when the disk unit is not locked in a non-operational state.Therefore, there is no danger of loss. Because of its large size, its storage management is easy.
