2. Description of the Related Art The following are known as input devices for control in remote control systems, microcomputers and the like.

A key input device for inputting by key operation, a mouse input device, a trackball input device for manually rotating a rotatable ball, a jog shuttle input device for manually rotating a rotating plate, and a joystick input device for moving a stick back and forth and right and left.

[0004]

The key input device has one function for each key. For example, two keys are required to move the cursor upward and downward. Therefore, a large installation space is required. Also,
There is a disadvantage that the operation cannot be performed unless the user looks at the hand.

[0005] The mouse input device and the trackball input device can move freely in four directions of up, down, left, and right, so that it is difficult to move the cursor in only one fixed direction. Mouse input devices require moving space.

Further, in order to treat the contents and the like designated by the control input device as valid, it is necessary to enter and execute instructions. To perform such an instruction, the mouse input device, the trackball input device, and the jog shuttle input device need to be separately provided with key switches.

The jog shuttle input device requires two-handed operation in the case of remote control. Furthermore, since the joystick input device generates an output signal with a switch that is turned on in accordance with the position of the stick, it is not suitable for changing the control amount in an analog manner in conjunction with the operation of the stick.

Further, as a control input device used for a device having a display device such as a CRT display, a key input device has been mostly used. Therefore, it is necessary to perform an input operation while viewing both the screen of the display device and a large number of keys.

Accordingly, an object of the present invention is to provide a transmission / reception device which can solve the above-mentioned problems of the conventional control input device.

Another object of the present invention is to provide a transmission / reception apparatus which can easily deal with a change such as an increase in controlled objects.
