The signal transmission from the switch elements 9, 10 and 11 to the control / drive circuit to the display elements D5 and D6 is performed through a circuit pattern (not shown) formed on the circuit board 5.

The first and second switch elements 9 and 10
Are fixed so that one side surface thereof faces the plate surface of the circuit board 5 through a metal frame (not shown). Further, the contact portions 12 and 13 of the first and second switch elements 9 and 10 have cutout portions 51 formed in the circuit board 5.
They are arranged so as to face each other with a pinch in between. The contact portions 12 and 13 may be arranged so as to face each other through the cutout portion 51 when the circuit board 5 is viewed from above.

The third switch element 11 is the circuit board 5
The contact portion 14 is located between the cutout portion 51 and the through hole 52, and protrudes in a direction orthogonal to a line (a plate surface of the circuit board 5) connecting the contact portion 12 and the contact portion 13.

At this time, the contact portions 12 and 13 are turned on to output a switching signal by rotating the knob S in the first direction R or the second direction L to release the rotation of the knob S. As a result, it returns to the normal position (turns off). Further, the contact portion 14 is turned on by outputting the switching signal by pushing the knob S in the direction of the arrow B,
It is designed to return (turn off) to the normal position by releasing the pushing motion of.

The knob S is made of, for example, black synthetic resin and extends toward the housing H and is exposed to the outside.
Shaft portion 15, a disc portion 16 extending from the first shaft portion 15 in an outer peripheral direction orthogonal to the axial direction, and the disc portion 1
A second shaft member 6 extending continuously from the first shaft member 15 and coaxially with the first shaft member 15.
Shaft portion 17 of

The disc portion 16 is housed in the penetrating portion 41 of the case body 4 (see FIG. 2), and the disc portion 16 has a third portion.
The flange portion 18 that extends toward the circuit board 5 (notch portion 51) side while covering the front of the switch element 11 and the elastic piece 19 that extends in the same direction as the flange portion 18 are integrally formed. In this case, the elastic piece 19 has the flange portion 18
Is provided above (the case body 4 side).

The flange portion 18 is formed of a stepped prism and has a pushing portion 20 facing the third switch element 11 when the knob S is in the normal position, and extends outward from the pushing portion 20. At the same time, it is provided with a rotation pushing portion 21 protruding toward the cutout portion 51. In this case, the rotary pusher 21
Is located between the first and second switch elements 9 and 10. Then, the first shaft portion 15 exposed to the outside by the user
When the portion is rotated in the first direction R, the rotary pusher 21 of the flange 18 activates the first contact portion 12 of the first switch element 9, and when rotated in the second direction L, the rotary pusher 21 is rotated. When the moving portion 21 actuates the second contact portion 13 of the second switch element 10 and the knob S is in the normal position, the first shaft portion 15 is pushed in the direction of arrow B to push the flange portion 18. The part 20 is adapted to actuate the contact part 14 of the third switch element 11.

The elastic piece 19 extends in a rod shape from above the side surface of the disc portion 16 toward the groove portion 42 side of the case body 4, and extends at the tip thereof in a direction substantially orthogonal to the axial direction thereof, and the groove portion 42. An elastic projection 22 is formed so as to be fitted along. The elastic projection 22 is formed in a cylindrical shape having upper and lower surfaces having a spherical shape, and when the first shaft portion 15 is rotationally operated, the flange portion 18 that is rotationally moved in conjunction with this is normally operated by releasing the rotational operation. It has a function as a return spring for returning to the position.

That is, since the elastic piece 19 is provided along the flange portion 18, when the flange portion 18 is rotated by the rotation operation of the first shaft portion 15 in the first direction R, the elastic piece 19 is formed. It tries to rotate in the first direction R in conjunction with the lunge portion 18. However, in the case of the present embodiment, the elastic protrusion 2 held in the groove 42 of the case body 4 is used.
The rotational movement of 2 is restricted, and the flange 1
The elastic piece 19 bends in a bow shape in a state where 8 operates the first contact portion 12 of the first switch element 9. Therefore, an elastic return force that acts to return the flange portion 18 to the normal position (normal position in the rotation direction) by rotating the flange portion 18 in the second direction L side acts on the elastic piece 19, and when the rotation operation is released, the flange portion 18 is released. Return to normal position. This allows
The flange portion 18 is arranged apart from the first and second switch elements 9 and 10, so that the knob S can be smoothly rotated.

The second shaft portion 17 has a pair of hook portions (not shown) formed on the tip side thereof, and between the hook portions, a first hook portion is formed along the axis of the first shaft portion 15. Shaft 1
A slit 23 extending to the 5 side is formed. The hook portions are inserted into the through holes 52 of the circuit board 5 and penetrate the circuit board 5, and the through holes 5 are formed on the back surface of the circuit board 5.
It is engaged with the outer peripheral edge of 2. An elastic member 24 made of a metallic coil spring that expands and contracts along the axis is provided on the outer peripheral portion of the second shaft portion 17 in the disk portion 16 and the through hole 52.
Has been inserted between and.

The elastic member 24 constantly urges the knob S in the counter-pushing operation direction (direction of arrow C) by its elastic return force, whereby the pushing portion 20 of the knob S is moved to the third switch. After the contact portion 14 of the element 11 is pushed, the knob S can be returned to the normal position (the pushing direction normal position), and after the knob S is returned, the knob S is moved by the elastic return force. It is designed to be held on the circuit board 5.

In such a structure, the first shaft portion 15
When is rotated in the first direction R, as shown in FIG. 5 (a), the rotation pusher 21 actuates the contact portion 12 of the first switch element 9, and the ON operation of this contact portion 12 causes the display element D6 to be turned on.
For example, the display of the time displayed in “11: 00 → 12:
00 ”. Then, when this rotation operation is released, the elastic piece 19 separates the rotary pushing portion 21 from the contact portion 12 by its elastic return force, whereby the rotary pushing portion 21 corresponds to the cutout portion 51 (normal position). It is designed to return to (see Fig. 4).

When the first shaft portion 15 is rotated in the second direction L, the rotation pushing portion 21 moves to the second position as shown in FIG. 5 (c).
The contact portion 13 of the switch element 10 is activated, and the ON operation of the contact portion 13 causes the display of the time displayed on the display element D6 to return to, for example, “11: 00 → 10: 00”. Then, when this rotation operation is released, the elastic piece 19 separates the rotary pushing portion 21 from the contact portion 13 by its elastic restoring force, whereby the rotary pushing portion 21 corresponds to the cutout portion 51 (normal position). It is supposed to return to. Therefore, the flange portion 18 extends in one direction from the side surface of the disk portion 16 and is arranged between the first and second switch elements 9 and 10, so that the flange portion can be aligned with the axis line of the knob S as in the conventional case. While it was sandwiched and formed in both directions (two directions),
In the present invention, since the knob S is formed to extend in one direction from the axis of the knob S, the knob S can be downsized.

When the first shaft portion 15 is pushed in the direction of arrow B, the pushing portion 20 actuates the contact portion 14 of the third switch element 11 as shown in FIG. When the section 14 is turned on, the display of the traveling distance displayed on the display element D5 is reset. When the pushing operation is released, the elastic restoring force of the elastic member 24 returns the knob S to the normal position, and at the same time, the pushing portion 20 is separated from the contact portion 14 so that the pushing portion 20 returns to the normal position. There is. As described above, according to the present invention, the rotary pusher 21 is attached to the flange 18.
And the pushing portion 20 are integrally provided, and the switch elements 9, 10 and 11 are centrally arranged around the flange portion 18. Therefore, for example, the third switch element 11 is provided on the flange portion 1
A dedicated flange portion, which is required when the knob S is provided at a position deviated from 8, is not necessary, and the flange portion 18 has a simple shape, and the knob S can be miniaturized.

Further, in the present embodiment, the operation direction restricting means F for restricting the operation direction of the knob S is provided so that the rotating operation and the pushing operation of the knob S described above cannot be operated at the same time. That is, as shown in FIGS. 5A and 5C, the first shaft portion 15 is rotated in the first direction R or the second direction L, and the rotary pushing portion 21 moves the contact portion 12 or the contact portion 13. In the activated state, the bottom surface 25 of the rotary pushing portion 21 is located on the plate surface 53 of the circuit board 5. At this time, the gap between the bottom surface 25 of the rotary pushing portion 21 and the plate surface 53 is set to be narrower than the gap between the bottom surface 27 of the pushing portion 20 and the contact portion 14, so that the first shaft portion 15 is indicated by the arrow B. When the pushing operation is performed in the direction, the bottom surface 25 of the rotary pushing portion 21 contacts the plate surface 53 of the circuit board 5. As a result, since the pushing operation of the knob S is restricted and the contact portion 14 cannot be pushed, only the rotating operation functions and the rotating operation and the pushing operation cannot be performed at the same time.

On the contrary, as shown in FIG. 5B, when the first shaft portion 15 is pushed in the direction of arrow B and the pushing portion 20 actuates the contact portion 14, the rotary pushing movement is performed. The portion 21 is inserted into the cutout portion 51. Therefore, the first shaft portion 15 is rotationally operated in the first direction R or the second direction L (FIG. 5).
(See (a) and (c)), and the first and second rotary pusher 21
The side surface 26 facing 9 and 10 contacts the inner side surface (side surface) of the cutout 51. As a result, the rotation operation of the knob S is restricted and the contact portion 12 or the contact portion 13 is restricted.
Since it is not possible to operate, the pushing operation only functions and the rotating operation and the pushing operation cannot be operated at the same time, so that the certainty of the operation of the knob S can be enhanced.

As described above, in the present embodiment, the knob S extending in a column shape, the display element D6 for displaying predetermined information, and the display element D6 by rotating the knob S in the first and second directions R, L. 1st and 2nd contact part 1 which switches the display information of
The first and second switch elements 9 and 10 having the second and the third parts 13 are provided, and the knob S is provided with the first and second contact portions 12 and 13 through rotation in the first direction R or the second direction L. By providing a flange portion 18 to be operated, and by arranging the first and second contact portions 12 and 13 so as to face each other through the flange portion 18, the flange portion is provided on each of the two switch elements as in the conventional case. Since it is unnecessary to extend the knob S, the knob S can be downsized.

Further, in this embodiment, the knob S is provided with the elastic piece 19 for returning the flange portion 18 to the normal position, so that after the rotation operation is released, the first and second switch elements 9 and 10 are flanged. The knob 18 is separated from the portion 18 to improve the operability of the rotation of the knob S.

Further, in this embodiment, the third and third switch elements 9 and 10 are provided in the vicinity of the flange portion 18 in the vicinity thereof.
By disposing the third switch element 11 having the contact portion 14 of the above, and by providing the pushing portion 20 for operating the third contact portion 14 by pushing the knob S on the flange portion 18, There is no need to provide a dedicated flange part for operating the contact part 14, and the knob is pushed.
It is possible to concentrate the rotary pushing operation part in one place.

Further, in this embodiment, when the knob S is rotated in the first direction R or the second direction L, the movement of the knob S in the pushing direction is restricted, and when the knob S is pushed, the knob S is moved. By providing the operation direction restricting means F for restricting the movement in the rotation direction, it is possible to prevent the rotating operation and the pushing operation from functioning at the same time, and to enhance the reliability of the knob operation.

Further, in this embodiment, the operation direction regulating means F
Since the operation direction can be regulated only by the knob S and the circuit board 5 by providing the between the flange portion 18 and the circuit board 5, a separate member is not required and the structure can be simplified. The operation direction restricting means F is not limited to this, and for example, the case body 4 may be integrally formed with a protrusion or the like that restricts the operation direction of the flange portion 18.

In the present embodiment, the elastic piece 19 is formed so as to extend in a rod shape, but the shape of the elastic piece 19 can be appropriately changed. For example, the elastic piece 19 may be formed to have a continuous curved shape. Good.

In this embodiment, the flange portion 18 is provided so as to face the first and second switch elements 9 and 10 at the normal position, but the present invention is not limited to this.
It suffices that the first and second switch elements 9 and 10 have a positional relationship in which they face each other via the flange portion 18 when the knob S is viewed from the axial direction. For example, the operation direction regulating means is abolished, the knob S is pushed and then the knob S is rotated, and thereby the first
The switch element 9 or the second switch element 10 may be operated. In this case, normally, the flange portion 18 of the knob S is not in the positional relationship of facing the first and second switch elements 9 and 10, but when the knob S is pushed, the flange portion 18 is moved to the first and second positions. 2 switch elements 9, 1
When the knob S is rotated in this position, the first switch element 9 or the second switch element 10 is activated.

In this embodiment, the knob S is operated in the first direction R or the second direction L to operate the first and second contact portions 12 and 13 for the purpose of downsizing the display device. A structure in which the flange portion 18 is provided and the first and second contact portions 12 and 13 are arranged so as to face each other via the flange portion 18 is adopted, but the operation direction of the knob S is not particularly aimed at downsizing. For the purpose of regulation only, the above-described miniaturization achievement configuration is achieved by "rotating the knob S in the first direction R or the second direction L through the first and second contact portions 1".
It is optional to employ a configuration in which a flange portion 18 for actuating the second and the third portions 13 is provided, and the first and second contact portions 12 and 13 are arranged to face each other via the flange portion 18.
In this case, “the first direction R or the second direction L of the knob S is
The operation direction restricting means F is provided for restricting the movement of the knob S in the pushing direction when rotating the knob S, and restricting the movement of the knob S in the rotating direction for pushing the knob S. " It may be performed. That is, conventionally, the operation direction of the knob S is regulated by a predetermined part such as a case body separately arranged from the knob itself and the circuit board. However, this makes the shape of the case body complicated. However, there is a problem that the manufacturing cost and the processing cost of the molding die are increased and the cost is increased. Therefore, by adopting the above-described operation direction regulation structure, it is not necessary to form a shape on the case body for regulating the operation direction, and the knob operation direction can be regulated by the knob itself and the circuit board. , The structure can be simplified.
