  The present invention relates to a remote control transmitter mainly used for remote control of various electronic devices.

  In recent years, as various electronic devices such as video, audio, and air conditioning have become highly functional, remote control transmitters that remotely operate these electronic devices can be operated in a variety of ways by increasing the operating functions by opening and closing and moving doors. Is increasing.

  Such a conventional remote control transmitter will be described with reference to FIGS.

  4 is a cross-sectional view of a conventional remote control transmitter, and FIG. 5 is an exploded perspective view thereof. In FIG. 4, 1 is a substantially box-shaped upper case made of insulating resin, 2 is an operating body such as rubber, and the operating body 2 is provided with a plurality of operation portions 2A connected to each other by a substantially dome-shaped thin portion below, and the upper surfaces of the plurality of operation portions 2A can be moved up and down from a plurality of opening holes on the upper surface of the upper case 1. It protrudes.

  Reference numeral 3 denotes a wiring board in which a plurality of wiring patterns (not shown) are formed on the upper and lower surfaces. The operating body 2 is placed on the upper surface, and a plurality of fixed contacts such as carbon are provided on the upper surface of the wiring board 3. 4A is provided, and the fixed contact 4A is opposed to the movable contact 4B made of carbon or the like formed on the lower surface of each operation portion 2A with a predetermined gap therebetween to form a plurality of switch contacts 4.

  In addition, 5 is an insulating resin door body, 6 is a pressing body such as rubber, and the pressing body 6 is provided with a plurality of push button portions 6A connected and formed by a substantially dome-shaped thin portion below, The upper surfaces of the plurality of push button portions 6A protrude from the plurality of opening holes on the upper surface of the door body 5 so as to be vertically movable.

  Further, reference numeral 7 denotes a plate-like cover made of an insulating resin. The cover 7 covers and fixes the lower surface of the door body 5, and the pressing body 6 is accommodated in the door body 5 with the lower surface abutting the upper surface of the cover 7. At the same time, the bottom surfaces of the plurality of push button portions 6A protrude from the plurality of opening holes on the bottom surface of the cover 7.

  The door 5 is attached to the upper case 1 so as to be openable and closable with a shaft hole 5A formed at the left end as a fulcrum, and the door 5 is closed and the upper surface of the operation portion 2A of the operation body 2 is closed. In the state of covering, the bottom surfaces of the plurality of push button portions 6A are in contact with the top surfaces of the plurality of operation portions 2A.

Then, the substantially dome-shaped thin portion is elastically deformed and the operation portion 2A moves downward, the movable contact 4B on the lower surface comes into contact with the plurality of fixed contacts 4A, and the switch contact 4 is electrically connected / separated. .

  Then, the control means 10 transmits a remote control signal from the transmission means 8 according to this electrical contact / separation. At this time, a detection switch (not shown) or the like provided separately between the door body 5 and the wiring board 3 is used. Thus, the control means 10 detects that the door 5 is in an open state, and transmits a remote control signal different from the case where the pressing operation is performed via the push button portion 6A to the electronic device, for example, the air volume or the wind direction. Switching, timer setting, etc. are performed by remote control.

  That is, the control means 10 detects the open / closed state of the door body 5 with a detection switch or the like, determines which of the push button portion 6A and the operation portion 2A is operated, and opens the door body 5 to directly press the operation portion 2A. And when the door 5 is closed and a pressing operation is performed via the push button portion 6A, by transmitting different remote control signals, it is possible to increase the function of remote operation and to perform various operations of the device. It was composed.

As prior art document information related to the invention of this application, for example, Patent Document 1 is known.
