[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric device for receiving a remote control signal, and particularly to an improvement in the arrangement of remote control signal receiving means.

[0002]

[Prior art]

 In recent years, devices operated by remote control signals emitted from remote controls have become widespread. Therefore, electric devices that receive remote control signals have been in high demand. In particular, in the field of in-vehicle equipment that requires excellent operability, its use has been focused and various improvements have been made in the past.

Here, a conventional example of an electric device for receiving a remote control signal will be described with reference to FIG. The electric device is adopted on the main body side of the device operated by the remote controller 5. The remote controller 5 emits a remote control signal R such as infrared rays.

The electric device has a frame 1. An escutcheon 2 is provided on the front surface of the frame 1. The escutcheon 2 is formed with a reception window 3 through which the remote control signal R passes. A light receiving section 4 is arranged as a means for receiving the remote control signal R on the back side of the receiving window 3. A device (not shown) operated by the remote control signal R is connected to the light receiving unit 4.

In order for the light receiving section 4 to obtain a wide light receiving range, it is necessary to arrange the light receiving section 4 facing the operation direction of the remote controller 5. Therefore, conventionally, the substrate 6 for the light receiving portion is provided in the frame 1 in the vertical direction. That is, the above need is satisfied by mounting the light receiving portion 4 on the light receiving portion substrate 6.

In the electric device having the above configuration, the remote control signal R emitted from the remote controller 5 passes through the reception window 3 and is received by the light receiving unit 4. At this time, since the light receiving section 4 is attached to the light receiving section substrate 6 and is arranged facing the operation direction of the remote controller 5, a wide light receiving range can be obtained. Therefore, the light receiving unit 4 can reliably receive the remote control signal R from the remote control 5.

[0007]

[Problems to be solved by the device]

 However, the above electric device has the following problems. That is, since the substrate 6 for the light receiving portion is provided, the number of members increases and the manufacturing cost rises. Therefore, it is disadvantageous in terms of man-hour and cost. In addition, the reliability of the device decreased because the number of parts increased.

The present invention has been proposed to solve such a problem, and by eliminating the substrate for the remote control signal receiving means, the number of members is reduced, the cost is reduced, and the reliability is improved. It is an object of the present invention to provide an electric device.

[0009]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to an electric device for receiving a signal radiated from a remote controller, the remote controller signal receiving means provided on a substrate arranged substantially parallel to the lower surface of the frame, and the front surface of the frame. A remote control signal receiving window, and a reflecting member provided on the back side of the remote control signal receiving window so as to direct the remote control signal passing through the remote control signal receiving window to the remote control signal receiving means. Is characterized by. Further, the present invention is characterized in that the reflecting member is a convex mirror.

[0010]

[Action]

 In the present invention having the above configuration, when the remote controller emits a remote control signal, the remote control signal passes through the receiving window and is received by the reflecting means. The reflecting means reflects the received remote control signal and directs it to the remote control signal receiving means side. The remote control signal receiving means receives the remote control signal reflected by the reflecting member.

In this way, since the reflecting member directs the remote control signal to the receiving means side, it is not necessary to dispose the remote control signal receiving means facing the operating direction of the remote control. Therefore, the vertical board for mounting the remote control signal receiving means is not necessary.

Further, by forming the reflecting member as a convex mirror, even if the incident angle of the remote control signal is slightly deviated from the horizontal direction, the convex mirror can accurately direct the remote control signal to the remote control signal receiving means.

[0013]

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2. This embodiment is adopted on the main body side of the device operated by the remote controller 5. Incidentally, the same members as those of the conventional example shown in FIG.

As shown in FIG. 1, in this embodiment, a reception window 3 is formed in the escutcheon 2 as in the conventional example. A horizontal substrate 7 is arranged substantially parallel to the lower surface of the frame 1. The horizontal board 7 is a board on which jack terminals 10 of devices operated by the remote controller 5 are arranged. A light receiving portion 8 is provided on the horizontal substrate 7 as a remote control signal receiving means. The light receiving portion 8 is directly attached to the horizontal substrate 7.

At a side edge portion of the lower surface of the frame 1 near the escutcheon 2, a support portion 11 that is vertically raised is provided. The upper end side of the support portion 11 is inclined upward 45 degrees toward the back side. A reflecting plate 9 serving as a reflecting member is provided on the surface of the inclined portion facing the receiving window 3. The light receiving portion 8 is arranged above the reflecting plate 9. The upper end side of the support portion 11 may be mirror-finished and the reflector 9 may be omitted.

Further, as shown in FIG. 2, metal plates 12, 12 are provided on both left and right sides of the reflection plate 9. The metal plates 12 and 12 are provided so as to guide the remote control signal R reflected by the reflection plate 9 to the light receiving unit 8.

In the present embodiment having the above-described configuration, when the remote controller 5 emits the remote controller signal R, the remote controller signal R passes through the receiving window 3 and is received by the reflector 9. The reflector 9 refracts the incident remote control signal R upward by 90 degrees and emits it. The light receiving section 8 receives the remote control signal R from the reflector 9.

As described above, since the reflector 9 directs the remote control signal R to the light receiving unit 8 side, it is not necessary to arrange the light receiving unit 8 facing the operation direction of the remote controller 5. Therefore, the vertical substrate for the light receiving section is unnecessary. Therefore, it is possible to reduce the number of parts and the manufacturing cost. As a result, it is advantageous in terms of man-hours and cost. Moreover, since the number of members is reduced, the reliability of the device is improved.

Further, in the present embodiment, the metal plates 12, 12 adjacent to the reflection plate 9 guide the remote control signal R to the light receiving unit 8. Therefore, the passage of the remote control signal R in the frame 1 is less affected than the outside. Therefore, the operability of the remote controller 5 is improved, and excellent performance can be secured as an electric device for receiving the remote controller signal R.

Further, in the present embodiment, the light receiving range of the light receiving unit 8 tends to be narrower than in the system in which the light receiving unit 8 is arranged facing the operation direction of the remote controller 5, but the present embodiment is limited. Since it is used in a vehicle, which is used in a limited space, even if the light receiving range is narrowed slightly, the light receiving accuracy itself is not adversely affected. On the contrary, since the light receiving area of the light receiving unit 8 is reduced, there is an advantage that the vehicle-mounted device is less likely to be affected by other external light.

The present invention is not limited to the above-described embodiments, but includes an electric device in which the reflecting member is a convex mirror. This embodiment corresponds to claim 2. According to this embodiment, the convex mirror accurately directs the remote control signal to the remote control signal receiving means even if the incident angle of the remote control signal is slightly deviated from the horizontal direction. Therefore, excellent performance can be exhibited as an electric device that receives the remote control signal R.

A reflective member may be attached to the escalation side of the frame. Further, the shape and size of each member can be selected as appropriate.

[0023]

[Effect of device]

 As described above, according to the electric device of the present invention, by providing the reflecting member for directing the remote control signal to the remote control signal receiving means, the substrate for the remote control signal receiving means can be eliminated, and the number of members can be reduced. We were able to reduce costs and improve reliability.
