  Further, as shown in FIGS. 2 and 3, the rear panel 17 is cut at a part of the outer peripheral portion of each hole 173 by being bent perpendicularly to the hole 173 toward the RCA jacks 12-14. A raised rectangular cut-and-raised portion 175 is formed. When each rear panel 17 is attached to the chassis 10 with screws, the cut and raised portions 175 come into contact with the corresponding grounding portions 122, 132, and 142 and are electrically connected to each other.

  In each cut-and-raised part 175, the length L from the surface of the surface 176 facing the RCA jacks 12 to 14 of the rear panel 17 to the front end is such that the rear panel 17 is greatly bent when the rear panel 17 is attached to the chassis 10. In order to prevent this, the thickness of the conductive member forming the rear panel 17 is approximately the same. Note that the length L is such that when the rear panel 17 is attached to the chassis 10, each cut-and-raised portion 17 comes into contact with the grounding portions 122, 132, 142 of the corresponding RCA jacks 12 to 14 and the chassis 10 of the rear panel 17. As long as the entire apparatus can be mounted, the length of the entire apparatus satisfies the radio wave standard and the electrostatic test standard. Further, the cut-and-raised portion 175 of each hole 173 is produced in the same process as the cut-and-raised portion 177 of the opening 174 described later.

  The rear panel 17 has an opening 174 larger than the outer shape of the connector 16 into which the connector 16 is inserted when the rear panel 17 is mounted on the chassis 10. Further, as shown in FIG. 2, in the rear panel 17, a rectangular cut-and-raised portion 177 is formed on a part of the outer peripheral portion of the opening 174 so as to be bent and formed substantially vertically toward the connector 16. ing. The cut-and-raised portion 177 guides the connector 16 so that it can be easily inserted into the opening 174 when the rear panel 17 is attached to the chassis 10.

  Next, attachment of the rear panel 17 to the chassis 10 will be described below. It is assumed that a front panel (not shown) is already attached to the front side of the chassis 10 facing the rear panel 17. As shown in FIG. 1, first, jack portions 121, 131 a, 131 b, 141 a, 141 b and connectors 16 of RCA jacks 12 to 14 and connectors 16 are inserted into openings 172, 174 of the corresponding rear panel 17, respectively. It is attached to the back side. Subsequently, the hole 103a of the chassis 10 and the hole 171 of the rear panel 17 are positioned so as to coincide with each other, and the hole 103a of the chassis 10 and the hole 171 of the rear panel 17 are screwed by screws (not shown). The After that, a cover (not shown) made of a conductive member such as iron and covering the upper surface and both side surfaces of the apparatus is attached, and the cover is screwed to the chassis 10.

  Next, the contact between the grounding portions 122, 132, 142 of the RCA jacks 12-14 when the rear panel 17 is screwed to the chassis 10 and the corresponding cut-and-raised portions 175 of the rear panel 17 will be described below. In the following, for convenience of explanation, the contact between the grounding portion 122 of the RCA jack 12 and the corresponding cut-and-raised portion 175 of the rear panel 17 will be described as a representative. Further, the contact between the grounding portions 132 and 142 of the RCA jacks 13 to 14 and the corresponding cut-and-raised portions 175 of the rear panel 17 is the same as described below. FIG. 4 is a diagram for explaining the contact between the grounding portion 122 of the RCA jack 12 and the cut-and-raised portion 175 of the rear panel 17 corresponding thereto. FIG. 4 is a schematic diagram when the back side of the DVD recording / reproducing apparatus is viewed from the top side. In order to facilitate understanding of the invention, the raised portion 175 shown in FIG. 4 is described so that the length from the surface 176 to the tip of the rear panel 17 is longer than the thickness of the rear panel 17.

  As shown in FIG. 4, screws 18 are inserted into the holes 103 a of the chassis 10 and the corresponding holes 171 of the rear panel 17, and the rear panel 17 is screwed to the chassis 10. At this time, the rear panel 17 is electrically connected to the chassis 10 by contacting the rear panel 17 and the chassis 10 by screws and / or via the screws 18. Further, in order to fix the RCA jack 12 to the rear panel 17 and bring the rear panel 17 and the grounding portion 122 of the RCA jack 12 into contact with each other, a screw 19 is inserted into the hole portion 173 of the rear panel 17 and the hole portion 123 of the RCA jack 12, The rear panel 17 and the RCA jack 12 are screwed with screws 19. The screws 18 and 19 are made of a conductive member.

  At this time, as shown in FIG. 4, even if the screw 19 is loose, the rear panel 17 is attached to the chassis 10 by being fastened to the screw, and the raised portion 175 is formed on the outer peripheral portion of the hole 173 of the rear panel 17. Therefore, the cut-and-raised part 175 reliably contacts the grounding part 122 of the RCA jack 12, and the grounding part 122 of the RCA jack 12 is electrically connected to the rear panel 17 through the cut-and-raised part 175 and grounded. Is done. At this time, even if the screws 19 are loose, the RCA jacks 12 are fixed to the chassis 10 by the screws 19 so that the RCA jacks 12 are detached from the printed wiring board 11 due to vibration. Inconveniences such as end are prevented.

  Furthermore, even if the RCA jack 12 does not need to be fixed to the rear panel 17 and the screw 19 is not used, the rear panel 17 is similarly screwed to the chassis 10 with the screw 18 and the outer periphery of the hole 173 in the rear panel 17 is used. Since the cut-and-raised part 175 is provided in the part, the cut-and-raised part 175 reliably contacts the grounding part 122 of the RCA jack 12, and the grounding part 122 of the RCA jack 12 is connected to the rear panel 17 via the cut-and-raised part 175. It is electrically connected and grounded to the rear panel 17.

  Therefore, as described above, in the DVD recording / reproducing apparatus of the present embodiment, when the rear panel 17 is screwed to the chassis 10 with the screws 18, the RCA jacks 12 to 14 are fixed to the rear panel 17, and the rear panel 17 Even if the screws 19 for contacting the grounding portions 122, 132, 142 of the RCA jacks 12-14 are loose, the cut-and-raised portions 175 are provided on the outer peripheral portions of the respective holes 173 of the rear panel 17, Each cut-and-raised part 175 securely contacts the grounding parts 122, 132, 142 of the corresponding RCA jacks 12-14, and the grounding parts 122, 132, 142 of the RCA jacks 12 are electrically connected to the rear panel 17 to be sure. Can be grounded. As a result, even if the screw 19 is loose, the radio wave standard and the electrostatic test standard can be satisfied.

  In addition, when the rear panel 17 is attached to the chassis 10 with screws, the RCA jacks 12 to 14 are fixed to the rear panel 17 and the rear panel 17 and the grounding portions 122, 132, and 142 of the RCA jacks 12 to 14 are in contact with each other. Even when the screws 19 are not required, since the cut-and-raised portions 175 are provided on the outer peripheral portion of the hole 173 of the rear panel 17, each cut-and-raised portion 175 is connected to the grounding portion of the corresponding RCA jack 12 to 15. 122, 132, 142 can be surely contacted, and the grounding portions 122, 132, 142 of the RCA jacks 12-14 can be electrically connected to the rear panel 17 and reliably grounded. Thereby, even when the screw 19 is not required, it is possible to satisfy the radio wave standard and the electrostatic test standard.

  Moreover, since the cut-and-raised portion 175 of each hole 173 is manufactured in the same process as the cut-and-raised portion 177 of the opening 174, the number of processes does not increase due to the production of the cut-and-raised portion 175.

  In the above embodiment, the shape of the cut-and-raised portion 175 that contacts the grounding portions 122, 132, and 142 of the RCA jacks 12 to 14 is rectangular.
