Description

The present invention relates to an optical disc apparatus having a built-in VCR.

  There are optical disc media that can record / reproduce data such as video and audio by irradiating a recording surface with laser light. As the optical disc media, CD media that mainly records / reproduces audio data and DVD media that mainly records / reproduces video data are used. These optical disc media are formed in a disk shape having a diameter of about 12 cm, and are rapidly spreading due to high portability, space saving, and almost no deterioration.

  On the other hand, video cassettes, which are tape media, have been used as video data recording media. Many users still record old video data in video cassettes, and VCRs are also used. In recent years, with the widespread use of DVD players / recorders, there is an increasing demand for dubbing old video data recorded in video cassettes onto DVD media.

  Therefore, an optical disk device incorporating a VCR has been developed. In the case of the VCR-integrated optical disk apparatus, since many parts such as a VCR unit and an optical disk unit are housed in a case, the articles are closely packed. In addition, wiring may be complicated.

  FIG. 7 is a plan view of a VCR integrated DVD recorder which is an example of a conventional VCR integrated optical disk apparatus. As shown in FIG. 7, the VCR integrated optical disc apparatus D incorporates a VCR unit 91, a DVD recorder unit 92, and an HDD unit 93 inside a housing 90. The housing 90 is provided with a back panel 901 protruding to the back side and a cooling fan 902 attached to the back panel 901.

  The VCR unit 91 includes a drive motor 911 for outputting a cassette medium insertion / ejection driving force, and an optical sensor 912 for determining insertion / ejection start / end timing.

  The DVD recorder unit 92 is attached with a flat cable 921 for transferring data. The flat cable 921 is connected to a control board 920 attached to the upper part of the DVD recorder unit 92, and is arranged so as to cut the gap between the DVD recorder unit 92 and the VCR unit 91 vertically.

  As shown in FIG. 7, the rotation shaft 910 of the drive motor 911 and the terminal 913 protruding from the optical sensor 912 substrate are arranged to protrude in the gap with the DVD recorder unit 92. In the VCR integrated DVD recorder C, when the operation time becomes long, the rotating shaft 910 and the terminal 913 may generate heat. In addition, the VCR integrated DVD recorder D is provided with a plurality of motors including a drive motor 911 and a plurality of members serving as vibration sources such as a cooling fan 902, and vibration is also generated.

  The signal flat cable 921 vibrates due to vibrations propagated from the plurality of vibration sources. When the flat cable 921 vibrates and comes into contact with the rotary shaft 910 or the terminal 913, the covering of the flat cable 921 is peeled off, and the signal line is short-circuited, resulting in malfunction or failure. Further, a large hole is formed in a portion where the cooling fan 902 is attached in order to distribute more air. The VCR unit 91 may malfunction because light enters the inside through the hole and the light is detected by the optical sensor 912.

  Therefore, in order to suppress the flat cable 921 from coming into contact with the rotating shaft 910 and the terminal 913 and to enter the cooling fan 902 through the mounting hole but not reach the optical sensor 912, the VCR unit 91 and the DVD recorder A partition plate 94 is erected in the gap between the units 2 to prevent the flat cable 921 from moving to the VCR unit 91 side and to block light from the mounting hole of the cooling fan 902 (Japanese Patent Laid-Open No. 5-94681). Issue).

On the other hand, the DVD recorder unit 92 is provided with an optical pickup for irradiating the DVD medium with laser light. The VCR-integrated DVD recorder C has a larger number of members that generate heat than the DVD recorder or a single VCR device, and is closely mounted, so that it is designed so that a large amount of cooling air flows. As the amount of cooling air increases, the amount of inflow of minute foreign matter such as external dust increases. The optical pickup provided in the DVD recorder unit 92 may cause a significant decrease in performance or cause a failure due to such foreign matter flowing in. Therefore, a dust cover is attached to the lower surface of the DVD recorder unit 92 to suppress foreign matter from flowing into the DVD recorder unit 92, thereby preventing the occurrence of problems due to foreign matter in the optical pickup.
See Japanese Patent Laid-Open No. 5-94681

  However, when the dust cover is attached, the space for attaching the partition plate 94 becomes small, and the attachment of the partition plate 94 is difficult. Even if the partition plate 94 can be attached, the number of parts increases. As the number of parts increases, it takes time and effort to mount the parts, and the gap between the parts of the VCR-integrated DVD recorder C is narrowed, resulting in reduced cooling performance.

  Accordingly, the present invention provides a VCR integrated optical disc apparatus having a structure capable of suppressing the flat cable from coming into contact with the high temperature portion of the VCR and suppressing light entering from the outside from reaching the optical sensor. For the purpose.

  Further, since the flat cable can be suppressed without adding a member, a sufficient gap can be formed, and a cooling air flow passage can be secured. This makes it possible to protect the electronic device from heat.

  Furthermore, since the light incident from the cooling fan is blocked by the guard part and the flat cable held by the guard part, it is possible to suppress the light from entering the sensor and causing malfunction.

  In the above configuration, the guard portion has an engaging portion integrally projecting from the tip portion toward the optical disc unit, and the engaging portion is a support portion erected orthogonally from the guard portion. And an engaging claw portion formed orthogonally from the front end side of the support portion, and the upper end portion of the flat cable is engaged and held by the support portion and the engagement claw portion. It may be. According to this configuration, it is possible to hold the flat cable more stably.

  As the high temperature portion, a rotation axis of a drive motor that outputs a driving force for inserting / ejecting the video cassette, or a timing for inserting / ejecting a video cassette mounted on a substrate standing in the gap is measured. The terminal which protruded from the said board | substrate of the sensor can be mentioned.

  The said structure WHEREIN: The said dust cover may be equipped with the reinforcement rib currently formed integrally while orthogonally crossing the said guard part.

  The VCR unit 1, the DVD recorder unit 2, the hard disk unit 3 and the like generate heat when driven. Since the VCR unit 1 and the DVD recorder unit 2 malfunction or break down due to heat generation, the cooling fan 102 provided on the rear panel 101 is driven, and the cooling air inside the VCR integrated DVD recorder A is driven. And the VCR unit 1 and the DVD recorder unit 2 are cooled. The greater the inflow of cooling air, the higher the cooling capacity.

  The DVD recorder unit 2 records / reproduces the DVD medium Dv by irradiating the DVD medium Dv with laser light. The DVD recorder unit 2 has an optical pickup (not shown) that outputs laser light. Optical members such as a laser light source, an objective lens, a collimator lens, and a photodiode are attached to the optical pickup. The laser light source of the optical pickup generates a lot of heat, and the DVD recorder unit 2 needs to be cooled compared to the VCR unit. The hard disk unit 3 also generates a large amount of heat.

  The cooling fan 102 is attached at a position closer to the DVD recorder unit 2 than the gap 103 of the rear panel 101 so that the cooling air flows through the gap 103 and more cooling air is blown to the DVD recorder unit 2. . The cooling fan 102 is fixed by being fitted into and fixed to a through hole 106 formed in the back panel 101.

  Since the optical pickup of the DVD recorder unit 2 is provided with an optical member, if foreign matter such as dust or dust adheres to the optical pickup, the performance may be degraded or the operation may not be performed. The DVD recorder unit 2 is often formed with the optical pickup exposed from the bottom. Furthermore, by introducing cooling air into the VCR integrated DVD recorder A, foreign matters such as dust and dust contained in the installation place atmosphere flow into the VCR integrated DVD recorder A.
