  As shown in FIG. 3, in the laminate 20, the conductor 20b and the conductor 20c are opposed to each other through an insulator 20e made of resin or the like, and the conductor 20b is fixed to the flexible insulator 20a. 20c is fixed to the flexible insulator 20d. The laminate 20 is sandwiched between the upper part 21a and the lower part 21b of the holding member 21. A pressing portion 22 is formed in a window portion 21 c provided on the upper portion 21 a of the holding member 21, and the pressing portion 22 can be bent with the upper portion 21 a of the holding member 21 as a fulcrum. When the pressing portion 22 is bent by applying a pressing force, the pressing portion 22 presses the flexible insulator 20a and the conductor 20b. Then, the flexible insulator 20a and the conductor 20b bend, and the conductor 20b and the conductor 20c come into contact with each other to energize. The pressing part 22 and the flexible insulator 20a, the conductor 20b, the conductor 20c, and the flexible insulator 20d located under the pressing part 22 constitute one pressing switch 23, and a plurality of pressing switches 23 are arranged in parallel. A group of switches (for example, 2 to 6) connected together becomes a channel changeover switch G2.

  The channel changeover switch G1 is also a switch aggregate in which a plurality of pressing switches similar to the channel changeover switch G2 are connected in parallel. As will be described in detail later, the channel selector switch G1 and the channel selector switch G2 are connected in parallel via a resistor.

  As shown in FIG. 2, the holding member 21 is wrapped by the exterior member 8, and a display portion 8a indicating that it is a channel changeover switch G2 and a display portion 8b indicating that it is a channel changeover switch G1 are provided on the surface. It has been.

  In the present embodiment, there are a plurality of push-type switches 23 constituting the channel switching switch G2 around the display unit 8a. The same type of channel operation is performed regardless of which of the push-type switches 23 constituting the channel switching switch G2 is operated, so that it becomes easy to reliably instruct the device to perform a desired operation.

  Similarly, in the channel changeover switch G1, a desired operation is performed by pressing any of a plurality of push-type switches constituting the channel changeover switch G1. The same applies to the volume control switches G3 and G4.

  Further, as shown in FIG. 2, the laminated body 20 is extended to form wiring end portions 20g of the channel changeover switches G1 and G2 and the volume control switches G3 and G4. In the present embodiment, the wiring end 20g of the channel changeover switches G1 and G2 and the volume control switches G3 and G4 that are the input means of the present invention, the wiring end 6a of the earphone 6 that is the output means, and the end of the antenna member 7 7 a is fixed to a common support member 9.

  FIG. 4 is a partially exploded perspective view showing another embodiment of the carrying aid according to the present invention. The carrying aid 31 shown in FIG. 4 differs from the carrying aid 5 shown in FIG. 2 in that the antenna member 30 is formed of a flexible flat cable (FFC) instead of being formed of a conductive cable. . Constituent elements common to the carrying aid 5 shown in FIG.

  The FFC having a configuration in which a planar conductor is sandwiched between flexible flexible insulators is attached to the back side of the holding member 21. The back surface side of the holding member 21 is a surface opposite to the surface on which the window portion 21c on which the pressing portion 22 is disposed is formed.

  FIG. 5 is a partial cross-sectional view of the channel selector switch G2 shown in FIG. 4 taken along line 5-5 and viewed from the direction of the arrow. In addition, illustration of the exterior member 8 is abbreviate | omitted in FIG.

  The laminated body 20, the holding member 21, and the press part 22 are the same as FIG. In FIG. 5, an antenna member 30 made of FFC is provided under a lower portion 21b of the holding member 21 via a shield layer 31 made of a conductive material.

  The antenna member 30 is obtained by laminating a flexible insulator 30b, a conductor 30c, and a flexible insulator 30d in this order on a synthetic resin flexible substrate 30a.

  In the present embodiment, since the shield layer 31 is formed between the antenna member 30 and the laminated body 20, noise mixed in the antenna member can be reduced. It is preferable to connect the shield layer 31 to the fourth portion 10 d of the plug terminal 10. In the present invention, all the grounding wirings can be connected to the fourth portion 10 d of the plug terminal 10.

  Although not shown, the laminate 20 is extended to form wiring ends of the channel changeover switches G1 and G2 and the volume control switches G3 and G4. The wiring ends, the wiring ends of the earphones, and the antenna member 30 The end is fixed to a common support member. Furthermore, the wiring end, the wiring end, and the end of the antenna member 30 are connected to a single plug terminal. The configuration of the wiring end is the same as that shown in FIG.

FIG. 6 is a circuit diagram of the carrying aid 5 shown in FIGS.
As described above, the wiring end portion 6a of the earphone 6 is connected to the first portion 10a of the plug terminal 10, the end portion 7a of the antenna member is connected to the second portion 10b of the plug terminal 10, and the wiring end portion 20g is electrically conductive. The body 20 b is connected to the third part 10 c of the plug terminal 10, and the conductor 20 c of the wiring end 20 g is connected to the fourth part 10 d of the plug terminal 10. The fourth portion 10d of the plug terminal 10 is a ground terminal that is grounded.

  The channel changeover switches G1 and G2 and the volume control switches G3 and G4 are all switch assemblies in which a plurality of push-type switches 23 are connected in parallel, and a resistance portion 20f is interposed between these switch assemblies. . For example, a high specific resistance material is formed into a pattern between the switch assemblies to form the resistance portion 20f, and the conductors 20b at the position of the pressing switch 23 are connected to each other via the resistance portion 20f. Alternatively, the pattern of the conductor 20b of the stacked body 20 shown in FIG. 3 can be narrowed between the switch assemblies, and the narrow portion can be used as the resistance portion 20f. The resistance value of the resistance portion 20f is several hundred Ω to several hundred kΩ, and preferably in the range of 1.8 kΩ to 22 kΩ.

 For example, when one of the push-type switches 23 constituting the channel changeover switch G1 is connected, the voltage drop for one resistor 20f is between the third portion 10c and the fourth portion 10d (ground terminal) of the plug terminal 10. It is interpreted that a channel switching operation has been ordered by reading this voltage drop on the portable device side.

  Alternatively, when any one of the push-type switches 23 constituting the volume control switch G3 is connected, a voltage drop corresponding to three resistance portions 20f is generated between the third portion 10c and the fourth portion 10d (ground terminal) of the plug terminal 10. It is interpreted that the volume adjustment operation is ordered by reading this voltage drop on the portable device side.

  Note that the present invention is not limited to carrying aids for portable television receivers, and can be used as carrying aids for all devices having an antenna and an input / output unit, such as mobile phones and personal information terminals (PDAs).
