An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a remote control main body according to an embodiment of the present invention, and FIG. 2 is an external view thereof.
Since this is the same as the conventional example shown in FIG. 11, the same reference numerals are given to the corresponding portions, and the description thereof will be omitted.

In FIGS. 1 and 2, reference numeral 1 denotes an angular velocity sensor, which is disposed so as to detect an angular velocity in a horizontal direction and an angular velocity sensor 1a for detecting a horizontal direction, and is disposed so as to detect an angular velocity in a vertical direction. A vertical direction detecting angular velocity sensor 1b. Reference numeral 15 denotes a counter, an up / down counter 15a to which a count-up signal 16a from the horizontal direction detecting angular velocity sensor 1a and a count-down signal 17a from the transmission IC 2 are input and a count value 18a to be output, and a vertical direction detecting angular velocity sensor 1b. count-down signal 17b from the count up-signal 16 b and transmission IC2 from is inputted, consists of an up-down counter 15b to count 18b is output.

Next, the operation of the above configuration will be described. In FIG. 2, the user moves the remote control main body 9 to the right 6a direction or the left 6b direction of the horizontal direction 6 or the upper direction 7 of the vertical direction 7.
When the camera shakes once in the direction a or the downward direction 7b, the angular velocity sensor 1a for detecting the horizontal direction moves in the horizontal direction, and the angular velocity sensor 1b for detecting the vertical direction moves in the vertical direction. When the camera shakes a plurality of times, the angular velocity sensor 1a or 1b is connected. The up / down counter 15a or 15b is counted up by the number of times it has swung, and count values 18a and 18b are output. The signal of the count value 18a or 18b is used as the transmission IC 2
Generates a pulse train signal of the corresponding code, outputs a countdown signal 17a or 17b each time transmission is performed, and counts down the up / down counter 15a or 15b. This operation is repeated until the count value output 18a or 18b becomes zero. By this,
A predetermined transmission signal is output from the infrared light emitting element 5 as many times as the user shakes the remote control main body 9. In this embodiment, even if the user shakes the remote control main body 9 earlier than the time required for transmitting the transmission signal, the operation information can be transmitted without malfunction. Here, the transmission IC 2
Many of these are composed of a microcomputer, but a pulse signal train of a predetermined code is generated by an output signal from the angular velocity sensor 1,
An infrared signal is transmitted from the light emitting element 5 via the driving circuit 4. Thereby, remote control of the electric device can be performed.

As described above, if the sensors 1a and 1b for detecting the angular velocities in the horizontal direction and the vertical direction are arranged, the right direction 6a, the left direction 6b of the horizontal direction 6 and the upward direction 7
The transmission IC can detect four parameters such as “a” and “downward” 7b. The size of the moving speed because it detects an analog value, it is possible to transmit and when swung faster, different transmission code by analog value corresponding to the moving speed when shaken Yutsukuri.

For example, if this remote control is used for a VTR, the remote control main body 9 is shaken upward 7a to play, the remote control main body 9 is shaken downward 7b to stop, and the remote control main body 9 is swung rightward 6a to fast forward. Fast forward depends on the speed of shaking,
The speed can be changed. If it shakes in the left direction 6b, it rewinds, and similarly, the speed can be varied according to the swinging speed.

When used in a TV, the upward direction 7a
Is channel up , down 7b is channel down,
Volume up in the right direction 6a, volume down in the left direction 6b,
In the directions 6a and 6b, the step of changing the volume can be changed according to the speed of shaking .
Rukoto is possible and that Do not. Note that the relationship between the swing direction and the operation function is
The staff is displayed on the appropriate part of the remote control body.
Needless to say. Also, the speed of shaking is fast
About two stages, slow or slow, are appropriate.

When the transmission IC 2 detects an angular velocity equal to or greater than a predetermined value, the transmission IC 2 moves the selection display marker 14 on the menu screen 13 displayed on the LCD 11 in the same direction in which the remote control main body 9 is swung. When the selection display marker 14 moves to the right end, the selection display marker 14 moves to the leftmost end of the lower row. In this manner, by swinging the remote control main body 9 in the left and right directions 6a and 6b, a certain function can be selected from the menu screen 13 of the LCD 11 provided in the remote control main body 9.

Next, confirmation is performed by shaking the remote control main body 9 in the up and down directions 7a and 7b, and the transmission IC 2 transmits a pulse train signal of a code corresponding to the selected function to the drive circuit 4.
