Description

  The present invention relates to a disk device for reproducing data recorded on a disk medium or recording data on the disk medium by rotating the disk medium.

  In recent years, thinning of disk devices has been desired. As the disk device becomes thinner, vibrations caused by rotating the disk media become a problem. In addition, static electricity may be generated when the user operates the disk device, causing electrostatic breakdown and a sense of incongruity for the user.

Patent Document 1 proposes a technique for pressing a drawer at two locations to control vibration. However, this proposal was not a proposal for solving the above-mentioned static electricity problem.
Japanese Patent Laid-Open No. 11-25558 (FIGS. 2, 3, 4, and 5)

  Accordingly, the present invention has been made in consideration of the above circumstances, and an object thereof is to prevent static electricity that causes electrostatic breakdown and a user's uncomfortable feeling.

  A disk device according to the present invention includes an electrically conductive casing in which a disk tray is accommodated, a disk tray on which the disk medium is placed, the disk medium is rotated to extract information recorded on the disk medium, A disk device main body that is provided on the disk tray and has electrical conductivity that suppresses vibration generated when the disk medium rotates by being pressed against the housing, and is electrically connected to the pressing member. And a bezel provided on the device.

  According to the configuration described above, it is possible to prevent static electricity that causes electrostatic breakdown and a sense of discomfort to the user.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an embodiment of the present invention and is an external view of a disk tray according to a disk device.

  Reference numeral 1 is a drawer, reference numeral 2 is a bottom plate, reference numeral 3 is a pickup, reference numeral 4 is a spindle motor, reference numeral 5 is a control pressing member 1, reference numeral 6 is a control pressing member 2, reference numeral 7 is a traverse mechanism, and reference numeral 8 is Reference numeral 9 denotes a bezel (front panel), reference numeral 9 denotes a switch, reference numeral 10 denotes a metal plate, and reference numeral 11 denotes an FPC (flexible printed circuit).

  In a thin disk device, the disk tray is configured by a pickup 3, a spindle motor 4, a mechanism for moving the pickup, and the like, and a traverse mechanism 7 for reading / writing data is attached to the drawer 1.

  When exchanging a disc medium such as a DVD or a CD, this portion of the disc tray protrudes forward, and the disc media is directly attached to and detached from the traverse mechanism. During playback or recording, the drawer 1 moves backward, is stored in a predetermined position in the housing, and rotates the disk media.

  As described above, the drawer 1 is configured to be movable in the front-rear direction. For this reason, in order to ensure the slidability, a certain amount of clearance (so-called looseness) is given to the housing.

  However, when the disk medium is rotated during reproduction or recording, vibration occurs. This vibration causes noise due to the clearance with respect to the housing, and has an adverse effect on reproduction and recording.

  Therefore, for vibration suppression (vibration suppression), mechanisms (control pressing member 1 and control pressing member) for pressing the drawer 1 against the side surface are provided at two locations inside the housing.

  In the disk device according to the present invention, the disk tray is configured to be storable and transferred to a casing (chassis) described later.

  A bezel (front panel) 8 is formed on the front side of the disc tray.

  The movement of the disc tray is driven by a user's hand or driven by a motor (not shown). The bezel 8 is provided with a switch (drive button) 9 and is configured to function as a trigger when the disk tray is pulled out from the housing.

  When the disc tray is configured to be driven by the user's hand, the disc tray is mechanically locked to the housing in a state where the disc tray is accommodated in the housing. When the user operates the switch (drive button) 9, the lock is released, and the disc tray is protruded from the housing by a predetermined amount by a spring (not shown). Further, when the user pushes the disk tray into the housing, the disk tray is mechanically locked to the housing.

  When the transfer of the disc tray is driven by a motor, the motor is driven by the user pressing a switch (drive button) 9 and the disc tray is pulled out from the housing. Further, when the user presses the disc tray by a predetermined amount by hand or presses the switch (drive button) 9, the motor is driven and accommodated in the housing.

  Further, the disk tray is provided with a drawer (disk storage unit) 1 in which a disk medium is stored, and a groove part in which a pickup 3 having a diode for irradiating a laser moves. The pickup 3 is transported in the radial direction of the disk accommodated by a transport mechanism (not shown) provided on the back side of the drawer (disc housing portion) 1.

  A signal read from the disk medium using the pickup 3 is output as a video signal or an information signal. The video signal and information signal output here are not particularly shown, but are displayed on a display device such as a liquid crystal or a cathode ray tube, or transmitted to an arithmetic device such as a personal computer.

  That is, the housing in which the disc tray is stored has electrical conductivity. The disc tray mounts the disc media, rotates the disc media, and uses the pickup 3 to extract information recorded on the disc media. The pressing member 1 (5) is configured to have electrical conductivity. The pressing member 1 (5) is provided on the disk tray and suppresses vibrations generated when the disk medium rotates by being pressed against the housing. The switch 9 is disposed near the bezel (front panel) 8. As will be described later, the bezel (front panel) 8 includes metal, and the casing electrically forms a ground. For example, static electricity generated in the bezel (front panel) 8 during user operation is pressed against the member 1 (5). It is configured to conduct to the housing through. As a result, electrostatic breakdown starting from the switch 9 can be prevented.

  FIG. 2 shows an embodiment of the present invention and is a diagram for explaining the configuration of a disc tray.

  The same components as those described above are denoted by the same reference numerals and description thereof is omitted.

  Here, the drawer 1 which is a part of the disc tray is stored in a predetermined position in the housing for reproducing the disc media or recording on the disc media. At this time, the drawer 1 is urged to the left by a vibration-suppressing pressing member 2 (6) constituted by a leaf spring or the like provided on the back side of the housing. Moreover, it is urged | biased on the left side also by the damping member 1 (5) comprised by the leaf | plate spring of the near side of drawing.

  Here, the vibration control mechanism on the near side (vibration control member 1 (5)) is provided for the convenience of the size of a general thin drive. And the space through which the disk media pass may conflict, so it must be installed on the drawer 1 side.

  Although the leaf spring (damping member 1 (5)) shown in FIG. 2 is hidden behind the drawer 1, it is not actually visible, but is shown for convenience of explanation. When the drawer 1 is housed in the housing, the leaf spring (the vibration damping member 1 (5)) is pushed in the C direction by the convex portion B of the housing. The leaf spring (damping member 1 (5)) pushes the casing in the direction A in the figure, and the drawer 1 is urged leftward by the reaction force. Thereby, the drawer 1 is damped. At this time, the leaf spring (damping member 1 (5)) and the bottom plate 2 are in an electrically conductive state.

  A metal plate 10 is disposed on the bezel (front panel) 8 so as to cover the front surface of the switch unit 9. It is desirable that one end of the metal plate 10 is in strong contact with the plate spring (damping member 1 (5)) by means of springiness, adhesion, screwing, soldering, etc. (D section). With these configurations, the metal plate 10, the leaf spring (vibration control member 1 (5)), and the bottom plate 2 are in an electrically conductive state, for example, electrostatic breakdown that occurs when the user touches the vicinity of the switch unit 9, Problems such as leakage of electromagnetic waves to the outside of the housing can be reduced.

  FIG. 3 shows another embodiment of the present invention, and is a diagram for explaining the configuration of a disc tray.

  Here, the torsion spring (damping member 1 (5)) shown in FIG. 3 is configured on the back side of the drawer 1 and is not actually visible, but is shown for explanation.

  When the drawer 1 is housed in the housing, the torsion spring (vibration control member 1 (5)) is pushed in the C direction by the convex portion B of the housing. Here again, due to the springiness of the torsion spring (vibration control member 1 (5)), the drawer 1 is urged leftward by the reaction force. As a result, the drawer 1 is damped. At this time, the torsion spring (damping member 1 (5)) and the bottom plate 2 are electrically connected. A metal plate 10 is disposed on the bezel 8 so as to cover the front surface of the switch unit 9. It is desirable that one end of the metal plate 10 is in strong contact with the torsion spring (damping member 1 (5)) by means such as springiness, adhesion, screwing, soldering (D portion). With these configurations, the metal plate 10, the torsion spring (damping member 1 (5)), and the bottom plate 2 are in an electrically conductive state, and electrostatic breakdown that occurs when the user touches the vicinity of the switch unit 9, It is possible to reduce problems such as leakage of electromagnetic waves to the screen.

  By configuring as described above, in the present invention, the vibration damping function and its own holding function are integrated. For this reason, there is an effect that the number of parts can be reduced, and it is possible to provide a structure that is inexpensive and reduces problems such as electrostatic breakdown and leakage of electromagnetic waves to the outside of the housing.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by variously modifying the constituent elements without departing from the spirit in the implementation stage.
