<Operation> The operation of the dial switch 11 in the operation device having the above-described configuration will be described. Here, in the natural state, the dial type switch 11 is
The balanced state is maintained at the "normal" position as shown in FIG. 3, FIG. 4 (b) and FIG. 5 (b) by urging the flange plate 33 from both sides by 4a and 34b.

(Temperature Adjustment Operation) First, the temperature adjustment operation will be described. When the operator pulls the knob 25 and displaces the dial switch 11 to the "pull" position as shown in FIG. 4A, the rod 31 is displaced in the direction indicated by the arrow in FIG. The first leaf spring contact 32a (1) of the direction displacement switch unit 26 is connected to the second groove contact 31b, and the second leaf spring contact 32b (C) is connected to the third groove contact 3
1c. Here, only the third leaf spring contact 32 c is insulated by the insulating resin 35 on the surface of the tip of the rod 31. As a result, as shown in the “pull” column in FIG.

The switch mode discriminating circuit 41 shown in FIG. 2 includes first and second leaf spring contacts 32a.
(1) Identify that only 32b (C) is short-circuited and transmit it to the control means 18.

In response, the control means 18 determines that the dial switch 11 is in the "pull" position by the mode determination function, and determines that the "temperature adjustment mode" has been instructed. The lamp switching instruction function gives the illumination switching processing circuit 59 an instruction to switch the second display unit 17 (color lamps 56 to 58) in accordance with the determined mode. As a result, the first color lamp 5 of the second display portion 17 disposed behind the front plate 25a of the knob 25
Only 6 lights red, and the side of the knob 25 except the front plate 25a turns red.

Here, the operator changes the knob 2 that has changed to red.
5 is rotated by a desired angle, the rotation displacement switch 27 of the dial switch 11 shown in FIGS.
Since the disk 37 of the (rotary encoder) rotates with the rotation of the rod 31, the signal from the light receiving element 39 is
The rotation amount of the dial switch 11 is transmitted to the control unit 18.

Then, the control means 18 recognizes the adjustment amount corresponding to the rotation amount of the dial switch 11 by the adjustment amount recognition function, and outputs a drive instruction signal to the air mix servo driver 21 by the drive instruction function. The servo motor 61 is driven to adjust the mixing ratio between the cool / warm air and the inside / outside air, thereby adjusting the temperature inside the vehicle.

At the same time, the control means 18 changes the image display on the liquid crystal display panel 45 of the first display unit 16, particularly the room temperature display 51, as specified by the image switching control function. Thereafter, the operator adjusts the rotation of the knob 25 while observing the change of the room temperature display 51 to adjust the temperature inside the vehicle.

(Blowing Position Adjustment Operation) Next, the blowing position adjustment operation will be described. When the operator leaves the knob 25 in the natural state as shown in FIG. 4B and the dial switch 11 is in the "normal" position, the rod 31 is moved to the position shown in FIG.
(B) Since the state is in the middle, the axial displacement switch section 26
Of the first leaf spring contact 32a (1)
a, the second leaf spring contact 32b (C) is connected to the second grooved contact 31b, and the third leaf spring contact 32c
By connecting (2) to the third groove-shaped contact 31c, all the leaf spring contacts 32a to 32c are short-circuited to each other through the inside of the rod 31 ("normal" column in FIG. 6).

Then, the switch mode identification circuit 41 shown in FIG. 2 identifies that all the leaf spring contacts 32a to 32c are short-circuited and transmits it to the control means 18.

In response to this, the control means 18 determines that the dial switch 11 is in the "normal" position and determines that the "blowing position adjustment mode" has been instructed. Then, a switching instruction is given to the illumination switching processing circuit 59, and the knob 25 is turned on.
Only the second color lamp 57 of the second display portion 17 behind the front panel 25a of the knob 25 lights yellow, and the front panel 2 of the knob 25 is turned on.
The side excluding 5a turns yellow.

Subsequently, when the operator rotates the knob 25,
The rotation displacement switch unit 27 (rotary encoder) of the dial switch 11 shown in FIGS. 3 and 7 transmits the amount of rotation to the control means 18, and as shown in FIG. A signal is output to the outlet switching servo driver 22, and the outlet switching servomotor 62 is driven to switch the air outlet position by switching a damper in a duct (not shown).

At the same time, the control means 18 changes the image display on the liquid crystal display panel 45 of the first display section 16, particularly, the blowout position display 53 as specified.

(Air Volume Adjustment Operation) Next, the air volume adjustment operation will be described. The operator operates the knob 25 as shown in FIG.
When the dial type switch 11 is displaced to the "push" position by pressing, the rod 31 is displaced in the direction shown by the arrow in the figure as shown in FIG. 5 (c), so that the second leaf spring contact 32b (C) is moved to the first groove. The third leaf spring contact 3
2c (2) is connected to the second grooved contact 31b. Here, only the first leaf spring contact 32a (1) is insulated by the insulating resin 35 on the surface of the rod 31. as a result,
As shown in the "push" column in FIG. 6, only the second and third leaf spring contacts 32b (C) and 32c (2) are rod 3
Shorted to each other through one internal conductor (not shown).
This is identified by the switch mode identification circuit 41 shown in FIG.

In response to this, the control means 18 determines that the "air volume adjustment mode" has been instructed, and the lighting switching processing circuit 5
9, the third color lamp 58 of the second display unit 17 behind the front plate 25 a of the knob 25 is lit green, and the side of the knob 25 except the front plate 25 a is green. Change.

Here, the operator rotates the knob 25, and based on the signal from the rotary displacement switch section 27 (rotary encoder) of the dial switch 11 shown in FIGS. 3 and 7, as shown in FIG. The encoder signal processing circuit 42 transmits the amount of rotation of the dial switch 11 to the control means 18. Then, the control means 18 outputs a drive instruction signal corresponding to the rotation amount of the dial switch 11 to the blower motor driver 23, and the blower motor 63 is driven to adjust the air volume.

At the same time, the control means 18 turns on the blower motor on display 54 of the image display on the liquid crystal display panel 45 of the first display section 16 by the image switching control function to indicate that the blower motor 63 is operating. At the same time, the air volume is displayed on the air volume display 55.

The rear defogger switch 12 is used to remove the fogging of the rear window, the inside / outside air changeover switch 13 is used to switch between the outside air introduction and the inside air circulation, and the air control switch is used to operate the compressor. If you want to keep the temperature inside the vehicle constant by activating thermistor, solar radiation sensor, etc.
When the user presses 5 respectively, the control means 18 performs appropriate control.

As described above, the "temperature adjustment mode" is set when the dial switch 11 is in the "pull" position, and the "blowing position adjustment mode" is set when the dial switch 11 is in the "normal" position. When the expression switch 11 is at the “push” position, the “air volume adjustment mode” is selectively set, and the adjustment is performed by rotating the dial switch 11 in each mode, as shown in FIG. It is not necessary to provide a dial switch for each of the modes selectively set as in the conventional example. Therefore, the operability of the operation device as a whole can be improved by reducing the occupied area of the three types of switches for temperature adjustment, blowing position adjustment and air volume adjustment.

<Modifications> (1) In the above embodiment, the switching of the axial position of the dial switch 11 is performed in three positions of "pull", "normal" and "push".
It is good also as many switching more than a position.

(2) In the above embodiment, a rotary encoder is used as the rotary displacement switch unit 27. However, any rotary encoder capable of converting a rotation angle into an electric signal, such as a rotary potentiometer using a resistor, is used. Such a thing may be used.

(3) In the above embodiment, the mode is set by illuminating the second display section 17 from behind the front plate 25a of the knob 25 of the dial-type switch 11 with lamps 56 to 58 of different colors. Although the operator is informed, for example, in the same liquid crystal area as the first display unit 16, the second display unit 17 blinks the display 51 to 55 corresponding to the item for which the mode is specified. Alternatively, the color of only the item may be changed.

(4) In the above embodiment, the winding spring 34
Has a structure that balances to the "normal" position, but this structure is abolished and the "normal" and "pull"
And a structure for holding each position of “push”.
