FIG. 3 is a block diagram showing the configuration of a control device connected to the rotary key 17 for controlling the operation of each function unit. In FIG. 3, reference numeral 31 denotes a rotary encoder as an encoder member connected to the rotary key 17,
32 is a code conversion device for converting the rotation of the rotary encoder 31 into code data, and 33 is a code conversion means 32
The control unit which analyzes the code data converted in the above and adjusts the operation to various functional units, 34 to 37 correspond to various functional units,
34 is a display function unit, 35 is a CD player, 36 is MD
A player 37 is a volume for volume control. The rotary encoder 31 calculates the amount of rotation of the rotary key 17 and sends a detection signal to the code conversion device 32. The control unit 33 adjusts the operation of the various function units 34 to 37 in accordance with the amount of rotation of the rotary key 17. Also,
The control unit 33 can control so as to adjust the operation of any of a plurality of functional units of the various functional units 34 to 37 in accordance with the amount of rotation of the rotary key 17.

The operation of the control device for an AV device having such a configuration will be described below. The control device basically operates an operation adjustment key (eg, a volume adjustment key 18) for each of various functional units attached to the operation panel 12 of the AV device, so that the operation adjustment key is assigned to the operation adjustment key. A corresponding operation can be instructed or controlled. Here, when the operator selects the control operation using the rotary key 17, the operation of the functional unit can be adjusted by operating the rotary key 17. In the control operation by the rotary key 17, the operation of all the functional units 34 to 37 can be adjusted by one rotary key 17. Therefore, for example, the operator selects a control operation using the rotary key 17 and operates the CD player 3 as a functional unit to be operated.
When 5 is designated, the operation of the rotary key 17 enters a mode for adjusting the operation of the CD player 35. When the rotary key 17 is set to the position of the operation adjustment mode mark 23 on the operation panel 12, for example, the position is determined by the rotary encoder 31 and a position detection signal is sent to the code conversion device 32. The code conversion device 32 analyzes the received position detection signal to code it, and sends this code data to the control unit 33. The control unit 33 generates a command corresponding to the code data, sends a control signal to the CD player, and causes the CD player to perform a reproducing operation. Thereby, reproduction of the CD is performed.

Next, as a function part operated by the operator, the rotary key 17 is kept set in the CD player 35.
Is set to the position of the operation adjustment mode mark 22 on the operation panel 12, for example, the fast-forward operation of the CD is performed by the processing operation of the control device similar to that described above.

Next, when the operator designates another function unit (for example, the display storage unit 34) as the function unit to be operated, the operation of the rotary key 17 enters a mode for adjusting the operation of the display function unit 34. . And in this mode, the rotary key 1
7 is a predetermined operation adjustment mode mark 21 on the operation panel 12
When the positions are adjusted to the positions of .about.24, the operation of the display function unit 34 corresponding to the position is adjusted.

The rotary key 17 can also adjust the operation of any of the various functional units 34 to 37 in accordance with the amount of rotation. For example, the CD player 35 and the display function unit 34 as the function units operated by the operator.
When the rotary key 17 is set to the position of the operation adjustment mode mark 22 on the operation panel 12, for example, the control device performs a fast-forward operation of the CD by the processing operation, and the position of the operation adjustment mode mark 22 becomes Since the display function unit 34 is at the position where the light blinking operation is adjusted, an operation such that the operation adjustment corresponding thereto is performed is also possible.

In the above description, the rotary key 17 has been described as having a rotatable knob button structure. On the contrary, the rotary key 17 can be "rotated". Alternatively, the switching may be performed by a “push” operation, and the switching may be performed by a “down” operation. By doing so, the function of the rotary key 17 can be further increased, and complicated operation adjustment can be performed.
