Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a disk device for recording and / or reproducing information on various optical disks.
[0002]
[Prior art]
In general, an information device such as a personal computer (hereinafter referred to as a personal computer) or a DVD recorder records information on an optical disk or reproduces information from the optical disk. Therefore, the disk device is indispensable and is built in these information devices. Or, it is connected as a so-called external cable.
[0003]
Such optical discs that are exclusively used for reproduction are CDs (Compact Discs), CD-ROMs (Read Only Memory), DVDs (Digital Versatile Discs), and DVD-ROMs (Read Only Memory), while recording There are optical discs such as CD-R (Recordable), CD-RW (ReWriteable), DVD-R, and DVD-RW that can be (added to).
[0004]
FIG. 9 shows a disk device 100 for driving such an optical disk D built in a desktop personal computer 101. A transport mechanism for loading / unloading the disk tray 103 is built in the housing 102. In addition, a drive mechanism such as a pickup base that operates when the disc tray 103 is loaded is incorporated (for example, Patent Document 1).
[0005]
As described above, the disk device built in the personal computer normally includes an optical pickup that is compatible with the above-described various optical disks, so that recording and reproduction of information on the optical disk can be processed alone. . The same applies to information equipment other than a personal computer with a built-in disk device, for example, a DVD recorder, and a single disk device is provided to record and reproduce information.
[0006]
In an information device incorporating a single disk device as described above, when information recorded on one optical disk is to be recorded on another optical disk, the information optical disk is first driven by the disk device. A record is temporarily held in a hard disk device or the like in the device body. Next, a recording optical disk is loaded into the disk device, the recording information of the hard disk device is read, and the information is written to the recording optical disk. As is clear from this, in order to be able to simultaneously process the recording / reproduction of the optical disk, it is provided with two disk devices for recording and reproduction, and the optical disk can be operated at the same time without having to replace the optical disk. Can be recorded simultaneously with playback.

According to a second aspect of the present invention, in the first aspect of the present invention, push buttons for loading / unloading the disc tray are provided at both side ends of the bezel.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0013]
FIG. 1 is a plan view of a disk device A having a configuration for realizing the present invention, and FIG. In the figure, reference numeral 1 denotes a chassis case serving as a housing of the disk device A, which accommodates a disk tray 3 integrated with the bezel 2, and chassis case 1 based on instructions for loading / unloading the disk tray 3. It has a built-in transport mechanism that moves forward and backward.
[0014]
The top surface of the chassis case 1 is formed with slits 1a penetrating inside at both end portions thereof, and the heads of the mounting screws when the disk device A is a two-stage set as will be described later. A recessed portion 1b is formed to avoid contact with the. On the other hand, a screw hole 1 c is formed at a position corresponding to the recessed portion 1 b on the bottom plate surface of the chassis case 1.
[0015]
FIG. 3 is a single side view of the disk device A, in which a screw hole 1d is formed at a position corresponding to the screw through hole of the inner housing formed in the information device main body P such as a personal computer. The screw hole 1d of the chassis case 1 and the screw hole 1d of the chassis case 1 are screwed at the same time, and the disk device A is fixed to the information device main body P. The chassis case 1 thus formed has a thickness H of 19 mm or more and 20.65 mm or less so that it can be disposed in a half-height drive bay, and a lateral width W of 145.5 mm or more and 146.5 mm or less. To do.
[0016]
Push buttons 4 for controlling loading / unloading of the disk tray 3 are disposed on the front face at both end portions of the bezel 2 fixed to the front end surface of the disk tray 3. Can be loaded / unloaded. The disk apparatus A also includes a turntable that rotatably supports the optical disk, a spindle motor that rotationally drives the turntable, an optical pickup that reads / writes information from / to the optical disk, and the optical pickup in the radial direction of the optical disk. It has a drive mechanism that moves it.
[0017]
Next, an assembly state when the disk device A configured as described above is integrated in a two-stage set will be described with reference to FIG. As shown in the figure, when the upper disk device is A1, and the lower disk device is A2, the bottom plate surface of the upper disk device A1 and the top plate surface of the lower disk device A2 are structurally connected. In this embodiment, the connecting member 5 is used in order to achieve the above state.
[0018]
The connecting member 5 is formed in a plate shape, and screw holes 5a and angle pieces 5b are formed at both ends thereof. The connecting member 5 thus formed is first fixed to the bottom plate surface of the upper disk device A1 by the mounting screw 6 so that the angle piece 5b protrudes. Next, the angle piece 5b is inserted into the slit 1a of the lower disk device A2 and slid to hold the top plate surface of the lower disk device A2 with the angle piece 5b. They are integrated as shown in FIG. In order to prevent displacement of the disk devices A1 and A2 assembled in this way, integration is further ensured by providing means such as further fixing the connecting member on the back surface thereof.
[0019]
When the thicknesses of the disk devices A1 and A2 integrated in this way are 20 mm and the thickness of the connecting member 5 is 1 mm, the total thickness by integration is 41 mm, which is exactly a half-height drive. Adaptable to the bay. Then, it can be arranged as shown in FIG. 6 by being fixed to the inner housing of the personal computer main body B by the screw hole 1d of the upper or lower disk device.
[0020]
The connecting member 5 is formed so that its width dimension is equal to or smaller than the width dimension of the disk device, and does not protrude to the side of the disk device when integrated with the disk device. Therefore, even in the case of a single unit or in the combined state, the width dimension does not change, so in any case, it can be installed in the half-height drive bay and can be attached to the information device P without any problem. . When separate disk devices are integrally configured in a two-stage set as described above, it is possible to arbitrarily set, for example, the upper row is a disk device dedicated to reproduction and the lower row is a disk device dedicated to recording. .
[0021]
By the way, when the disk device is configured in a two-stage set as described above, both disk devices are in close contact with each other, and when the disk tray 3 of the upper disk device A1 is unloaded as shown in FIG. The bezel 2 of A2 is hidden. On the other hand, when the disk tray 3 of the lower disk apparatus A2 is unloaded as shown in FIG. 8, this disk tray 3 becomes an obstacle to the operation of the upper disk apparatus A1.
[0022]
Due to such problems, in the present invention, push buttons for loading / unloading the disk tray 3 are provided on both sides of the bezel 2. Thereby, even when the disk tray of one disk device is unloaded, the usability of the other disk device can be prevented from being lowered.
[0023]
In addition, when the disk device of the present invention is disposed alone in a half-height drive bay, a gap is generated at the upper or lower portion of the disk device. In this case, an attachment member that covers the gap is prepared, and this is used. By wearing, the appearance of the front face can be maintained.
[0024]
【The invention's effect】
As described above in detail, according to the invention described in claim 1 of the present invention, the outer shape of the casing portion is set to a thickness of 19 mm or more and 20.65 mm or less, and a lateral width of 145.5 mm or more and 146.5 mm or less. Since the disk device is configured, it can be arranged in a half-height drive bay alone or in a two-stage set. Since separate disk devices can be integrated by the connecting member, it is possible to arbitrarily determine that the disk device for reproduction or recording is an upper stage or a lower stage. The configuration can be made highly flexible.
[0025]
According to the second aspect of the present invention, the push button for loading / unloading the disk tray is provided at both end portions of the bezel, so that even when the disk tray of one of the disk devices is unloaded, The usability of the other disk device is not lowered.
