An object of the present invention is to provide an operating device that can be downsized and that is easy to operate.

Means for Solving the Problems The present invention has a pair of guide members having guide elongated holes intersecting with each other, and a rotary shaft extending in the longitudinal direction and fixed to both end portions in the longitudinal direction of each guide member. Then, a variable resistor for deriving an electric signal corresponding to the angular displacement of the rotating shaft, a push button whose switching mode is changed by a longitudinal force acting on the guide member, and an operation commonly inserted through the guide slot A rod, a push-lock mechanism attached to the base end of the operating rod, which alternately holds the operating rod at a first position and a second position in the axial direction of the operating rod each time the pressing operation is performed; An operation including means for allowing mutual displacement of the operating rod and the guide member when in the first position, and preventing mutual displacement of the operating rod and the guide member when in the second position. It is a device.

Action According to the present invention, the operation rod and the guide member are allowed to displace each other when the operation rod is in the first position by the action of the push-lock mechanism. Therefore, by displacing the operating rod along the guide elongated hole of the guide member, the rotary shaft of the guide member and thus the variable resistor is angularly displaced with its longitudinal direction as an axis. Therefore, the resistance value of the variable resistor changes.

Another locking protrusion 47 is formed. This locking protrusion
47 can be locked in the notch 48 formed in the guide long hole 31 of the guide member 16 in the second position. In such a locked state of the locking projections 46, 47 with the guide members 15, 16, the mutual displacement of the operating rod 25 and the guide members 15, 16 is blocked. In the first position, the locking projections 46, 47
Are below the guide members 15 and 16 in FIG. 4 and are not in contact with each other. At the first position of the operating rod 25, the locking protrusion
The notch 49 of the angular displacement prevention member 48 is locked to the 47. The base end of the angular displacement prevention member 48 is the casing of the variable resistor 26.
It is fixed to 26a. Therefore, the rotational force around the axis of the operating rod 25, that is, the locking member 45, which is generated by the swinging operation of the operating rod 25, is caused by the locking projection 47 being locked in the notch 49 of the angular displacement blocking member 48. Be blocked.

FIG. 12 is a sectional view of the push-lock mechanism 27. In the push-lock mechanism 27, the shaft 57 partially inserted in the housing 56 is a casing 26a of the variable resistor 26.
This shaft 57 has an axis line on a straight line passing through the axes of the operating rod 25 and the shaft 28. Axis 28 is housing 56
Stuck to. The shaft 57 is biased in the housing 56 by a spring 58 upward in FIG. A moving protrusion 59 is fixed to the shaft 57. The moving protrusion 59 faces the driving member 60, and the driving member 60 is moved by the spring 61.
Is biased to the side.

FIG. 13 is a front view of the driving member 60 facing the moving protrusion 59,
FIG. 14 (1) is a sectional view taken along section line AA of FIG. 13, and FIG. 14 (2) is a sectional view taken along section line BB of FIG. FIG. 14 (3) is a section line C- of FIG.
It is sectional drawing seen from C. When the moving protrusion 59 is at the moving position 63 of the drive groove 62 formed in the drive member 60,
The operating rod 25 is in the second position.

By pressing the knob 36, the moving protrusion 59 at the moving position 63 reaches the moving position indicated by the reference numeral 65 from the moving position indicated by the reference numeral 64. After that, when the pressing operation of the knob 36 is released, the shaft 57 is moved by the spring force of the spring 58, and thus the moving protrusion 59 reaches the position 67 via the step 66, and is stabilized in this state, and the operating rod 25 It is in the first position.

To move the operating rod 25 from the first position to the second position, the knob 36
Press again. As a result, the moving protrusion 59 at the moving position 67 becomes the moving position indicated by reference numeral 68. Then, when the pressing operation by the knob 36 is released, the moving protrusion 59 returns from the moving position 69 to the moving position 63 via the step 70 by the spring force of the spring 58. Thus, the operating rod 25 is in the second position. Therefore, the push-lock mechanism 27 alternately holds the operating rod 25 and thus the locking member 45 at the first and second positions each time the knob 36 is pressed.

Due to the operation of the push-lock mechanism 27, the operation rod 25
As shown in FIGS. 10 and 10, when in the first position,
The sliding contact pieces 52, 53 are in sliding contact with the notches 41, 48 formed in the guide elongated holes 30, 31 of the guide members 15, 16. Therefore, a feeling of moderation can be obtained in the rocking operation of the operating rod 25 by the knob 36, and the rocking operation of the operating rod 25 can be performed. By the swinging operation of the operating rod 25, the rotary shafts 32 to 35 are angularly displaced, which changes the resistance values of the variable resistors 17 to 20. When the operation rod 25 swings, the rotary shafts 32 to 35 are urged outward in the axial direction by a large spring force.
32-35 do not displace in their axial direction. Therefore, the switching mode of the push buttons 21 to 24 does not change.

The angular displacement blocking member 48 is locked to the locking projection 49 at the first position of the operating rod 25. Therefore, when the operating rod 25 is angularly displaced around its axis by operating the knob 36, the variable resistance is changed. The rotary shaft 37 of the container 26 is angularly displaced. This allows variable resistors
26 resistance changes.

When the knob 36 is pressed to move the operating rod 25 to the second position, the locking projections 46 and 47 are locked to the notches 41 and 48 formed in the guide members 15 and 16, and the locking member 45 is used. Gatsute Operation Rod 25
And the mutual displacement of the guide members 15 and 16 is prevented. That is, when the operating rod 25 is in the first position, the sliding contact pieces 52, 53 are locked in the notches 41, 48, and in this state, the knob 36 is placed to bring the operating rod 25 to the second position. By pressing, the locking projections 46, 47 are locked in the notches 41, 48 in which the sliding contact pieces 52, 53 were locked. In this way, the sliding contact piece 5
The reference numerals 2 and 53 serve to obtain a feeling of moderation at the time of the above-described operation, and also to enable the locking projections 46 and 47 to be smoothly locked in the notches 41 and 48.

In the second position of the operating rod 25, when the locking projections 46, 47 are respectively locked in the notches 41, 48 of the guide members 15, 16 and the knob 36 is operated to swing the operating rod 25. , The rotary shafts 32 to 35 are displaced in the axial direction. These rotation axes
The switching mode of the push buttons 21 to 24 is changed by the displacement of the buttons 32 to 35.

The variable resistors 17 to 20 can be used to adjust the left and right balance and the front and rear fades of four speakers provided in the vehicle compartment in an on-vehicle audio device. Further, the push buttons 21 to 24 can be used for raising and lowering the reception frequency when receiving a radio broadcast, and for switching between amplitude modulation broadcast and frequency modulation broadcast. The second position can also be used for fast-forwarding, rewinding, stopping, ejecting, and a predetermined program reproducing operation of the magnetic tape during the magnetic tape reproducing operation.

With respect to the push-lock mechanism 27, push buttons having different switching modes may be attached at the first position and the second position.
