The plurality of upper operation bodies 15 that are transparent are connected and formed so as to be movable up and down by a substantially dome-shaped thin portion provided below.

  Further, the upper surface of the upper operation body 15 protrudes from the opening hole 4A on the upper surface of the door body 4, and a plurality of through holes 4B are provided on the bottom surface of the door body 4 so as to form a protruding pressing portion formed on the lower surface of the upper operation body 15. 16 protrudes from the through hole 4B toward the lower operation body 12 below.

  Reference numeral 10 denotes a light emitter such as a light emitting diode, which is mounted on the wiring board 3 on the lower surface of the lower operation body 12, and the light of the light emitter 10 illuminates the lower operation body 12 with light transmission from the lower surface. A light guide means is formed so as to illuminate the upper operation body 15 that passes through the body 12 and is light transmissive, thereby constituting a switch device.

  As shown in the plan view of FIG. 2, the plurality of upper operating bodies 15 and 15A housed in the door body 4 are normally used frequently such as turning on / off the power of the electronic device, volume or tuning. On the other hand, the plurality of lower operation bodies 12 and 12A, 12B in the case 1 are used for things with relatively low frequency of use such as mode switching between TV and video and time setting.

  Further, on the upper and lower surfaces of the wiring board 3, there are formed transmission means 7 for transmitting a remote control signal by electronic components such as light emitting diodes, and control means 18 such as a microcomputer connected to a fixed contact or the like via a wiring pattern. At the same time, a detection means such as a detection switch (not shown) is provided between the case 1 and the door body 4 so that the control means 18 determines whether the door body 4 is moving leftward or rightward. A remote control transmitter is configured to detect.

  In the above configuration, as shown in FIG. 1 and FIG. 2A, when the lower operation body 12A protruding from the opening hole 1A on the upper surface of the case 1 is pressed with the door body 4 moved leftward, The substantially dome-shaped thin-walled portion is elastically deformed to move the lower operation body 12A downward, the movable contact on the lower surface comes into contact with the fixed contact, and the switch contact is electrically connected / separated.

  Then, in response to the electrical contact / separation of the fixed contact on the lower surface of the lower operating body 12A, the control means 18 transmits an infrared remote control signal from the transmission means 7 to the electronic device, for example, the mode switching between the TV and the video can be performed remotely. Done by operation.

  Also, as shown in FIG. 2B, when the door 4 is moved to the right and the lower operating body 12 or 12B is pressed, the electrical connection of the fixed contacts on the lower surface of the lower operating body 12 or 12B is similarly performed. For example, the video recording time is set.

  On the other hand, as shown in FIG. 1 and FIG. 2 (a), when the upper operation body 15A protruding from the opening hole 4A on the upper surface of the door body 4 is pressed with the door body 4 moved leftward, The substantially dome-shaped thin-walled portion is elastically deformed to move the upper operating body 15A downward, and the pressing portion 16 protruding from the through hole 4B on the lower surface presses the lower operating body 12B. Electrical contact and separation of the fixed contact on the lower surface of the body 12B is performed.

  However, at this time, the control means 18 detects that the door body 4 is moved in the left direction by a detection means such as a detection switch, and from the transmission means 7, what is the pressing operation of the lower operation body 12B? Different, for example, remote control signals for turning on / off the device are transmitted.

  That is, in addition to the operations of the plurality of lower operation bodies 12A and 12B, the door body 4 is moved left or right, and this is detected by the control means 18, and the lower operation body 12 is defined by the plurality of upper operation bodies 15. By performing different operations, the remote control function is increased and more operations are possible.

  Further, when such a remote control transmitter is used in a dark place such as an automobile, when a separately provided changeover switch (not shown) or a predetermined lower operation body 12 is operated, The control means 18 causes the light emitter 10 such as a light emitting diode on the wiring board 3 to emit light.

  And since the light of this light-emitting body 10 illuminates the lower operation body 12 of milky white, transparent, etc. and light transmissive from below, the entire lower operation body 12 is illuminated and the lower operation protruding from the opening hole 1A of the case 1 The pressing position can be confirmed even in a place where the upper surface of the body 12 shines and the surroundings are dark, and the operation can be easily performed.

  Further, as shown in FIG. 1 and FIG. 2A, in the state where the door body 4 has moved to the left, the light passing through the lower operation body 12 or 12B passes through the pressing portion 16 and the upper operation body 15 or When the entire 15A is moved to the right as shown in FIG. 2 (b), the light that has passed through the lower operation body 12A illuminates the upper operation body 15A and the like. It is possible to easily check the position of the operating body 15.

  That is, by forming a plurality of lower operation bodies 12 and upper operation bodies 15 as light-transmissive light guides that are milky white or transparent as a whole, the light from the light emitter 10 moves down the lower operation body 12 from the lower surface. While illuminating, it passes through the lower operation body 12 and is also configured to illuminate the upper operation body 15 above.

  Therefore, it is not necessary to provide the light emitter 10 or the like for illuminating the upper operation body 15 in the door body 4, and it is not necessary to connect to the wiring board 3 by a lead wire or the like. In addition, a switch device and a remote control transmitter can be formed at a low cost.

  Furthermore, the control means 18 detects the movement of the door body 4 by a detection means such as a detection switch, and the control means 18 controls the light emission of the light emitter 10 in response to this, for example, the door body 4 moves. When only the lower operating body 12 and the upper operating body 15 are illuminated or the door body 4 is not moved for a predetermined time, that is, when the remote control transmitter is not used, light is emitted for power saving. Various illuminations such as turning off the body 10 can also be performed.

  As described above, according to the present embodiment, the light emitting body 10 that illuminates the lower operation body 12 accommodated in the case 1 so as to be movable up and down is provided from below and moved to the lower operation body 12 and the upper surface of the case 1. By forming a light guide on the upper operation body 15 in the door body 4 that can be mounted, the light of the light emitter 10 that illuminates the lower operation body 12 also illuminates the upper operation body 15. 4 does not need to be provided with a light emitter 10, etc., and connection with a lead wire or the like is not required, and an inexpensive switch device capable of illuminating the upper and lower operation bodies with a simple configuration, and remote control transmission using the switch device You can get a chance.

  The plurality of lower operation bodies 12 and upper operation bodies 15 are described as a configuration in which the entire operation body is illuminated by forming the light guide means by making the entire body milky white or transparent and transmitting light. The outer periphery of the lower operation body 12 or the upper operation body 15 is covered by two-color molding, etc., light is transmitted through the light guide means provided therein, and light-transmitting displays such as characters and symbols are provided on the upper surface and side surfaces. It is good also as a structure which illuminates only a part.

  Furthermore, although it demonstrated as a structure which connected the some lower operation body 12 and the upper operation body 15 and was able to move up and down by the substantially thin dome-shaped thin part of the lower part, the separate lower operation body 12 and the upper operation body 15 were demonstrated. In addition to the configuration in which the movable contact on the lower surface of the lower operating body 12 and the fixed contact on the upper surface of the wiring board 3 are opposed to each other, the switch contact is substantially dome-shaped on the fixed contact on the upper surface of the wiring board 3. Various switch contacts may be used such as one in which a movable contact made of a conductive metal thin plate is placed, or one in which a plurality of individual push switches are mounted on the wiring board 3.

  The switch device and the remote control transmitter using the switch device according to the present invention are inexpensive and capable of illuminating the upper and lower operation bodies with a simple configuration, and are useful mainly for operating various electronic devices.
