Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control signal transmitting device (hereinafter referred to as a remote control device) that can be used in electronic equipment such as a television receiver.

2. Description of the Related Art In recent years, it has become common for home appliances such as television receivers to be operated at hand, and remote control devices are being used more frequently. Furthermore, there is a high demand for products equipped with remote control devices for various electronic devices other than television receivers, and remote control devices have become widespread in most home appliances.

Hereinafter, an example of the above-mentioned conventional remote control device will be described with reference to the drawings.

Figure 9 is a plan view showing the state in which the conventional remote control device is held naturally, Figure 7 is a plan view showing the state in which the remote control device is used, Figure 7 is a perspective view showing the entire remote control device, and Figure 8
The figure is a side sectional view of the remote control device.

In FIG. 8, 81 is a lower lid that holds a printed circuit board 82 constituting a remote control control circuit, 83 is a button, 84 is a rubber contact plate integrated with the button 83 placed on the printed circuit board 82, and 85 86 is a top cover, and 87 is a light emitting diode (LED) that emits a remote control control signal.
88 is an LED protection molded product that protects the light emitting diode.

In the remote control device configured in this manner, when the button 83 is pressed, a remote control control signal generated in the remote control control circuit (printed circuit board 82) is output from the LED 87.
For example, it emits infrared light.

Problems to be Solved by the Invention In the configuration of such a conventional remote control device, when the remote control device is held naturally with one hand, the angle ( It will emit light in the direction of the arrow). Therefore, in order to emit light upward rather than toward the television receiver 91, it is necessary to lower the wrist a little and angle the remote control device 9Q to be close to horizontal with the floor, as shown in (■) in the same figure. However, there is a problem in that the remote control signal cannot be transmitted to the receiver at the first time and the operation has to be performed again because the operability is not good.

In addition, when controlling both a television receiver and a video tape recorder (VTR) with one remote control device, when controlling a product in which the television receiver and VTR are housed in a single cabinet, , it was necessary to transmit remote control signals by changing the angle of the remote control device relative to the television receiver and VTR. Therefore, even if it would be more convenient to control the television receiver and VTR at the same time, such as by controlling the power switch on/off, the operation cannot be performed in one go and must be repeated. Even if the VTR was turned off, there were problems such as forgetting to turn it off when the VTR was turned on.

The present invention solves the above problems, and an object of the present invention is to provide a remote control device having a plurality of transmission control angles.

Means for Solving the Problems In order to achieve the above object, the remote control device of the present invention has the following features:
The device is equipped with a transmitting element that transmits a remote control control signal with an angular difference in at least one of the horizontal and vertical directions.

Function: The remote control device of the present invention has the above-described configuration, and remote control control signals are transmitted from a plurality of transmitting elements having different transmission directions.

EXAMPLES Hereinafter, examples of the present invention will be described with reference to the drawings.

Figure 3 is a plan view showing how the remote control device is used in the first embodiment of the present invention. The case where it is placed and used is shown. FIG. 1 is a perspective view showing the entire remote control device, and FIG. 2 is a side sectional view of the remote control device.
