After using the jig 21 in which the 1b is erected and fixed, it is assembled in the following procedure.

First, the two positioning pins 21 of the jig 21
The mounting plate 17 is mounted on the jig 21 by inserting the two through holes 18c formed in the rear wall 18 of the mounting plate 17 into the b. Next, the two positioning pins 21 b of the jig 21 are inserted into the two through holes 16 c formed in the rear end of the moderating plate 16, and the moderating plate 16 is mounted on the jig 21.

Since the position of the moderating plate 16 with respect to the mounting plate 17 is determined by the two positioning pins 21b, when the moderating plate 16 is brought into contact with the rear wall 18 of the mounting plate 17, the position of the moderating plate 16 with respect to the mounting plate 17 is reduced. When the moderating plate 16 is not displaced, when the pair of projections 3c of the support member 2 are inserted into the pair of locking holes 16d and 18d of the moderating plate 16 and the mounting plate 17, they are strongly fitted. Even when the rotary encoder 1 is assembled, the pair of protrusions 3c of the support member 2 can be easily inserted into the pair of locking holes 16d and 18d of the moderating plate 16 and the mounting plate 17 after the rotary encoder 1 is assembled. Since it is locked by fitting, there is no play in attaching the moderating plate 16 to the attaching plate 17, and there is no shift in the attaching position.

The rotary encoder 1 constructed and assembled as described above is used, for example, by attaching it to a circuit board 22 on which a circuit pattern (not shown) is formed as shown in FIG. That is, three terminal insertion holes 22a and two attachment holes 22b are formed in the circuit board 22, and the rotary encoder 1 is attached to each of the attachment holes 22b by locking the attachment legs 19b. Hole 22a
Are electrically connected to the circuit pattern by solder 23 for use.
At this time, since the mounting leg 19b is not soldered, the rotary encoder 1 is in a state where it can be tilted in the direction of arrow A with the contact portion P3 between the extending portion 18e and the circuit board 22 as a fulcrum. In addition, no load is applied to the margins 5a, 6a, 7a provided at the terminals 5, 6, 7, and the terminals have the natural length S1.

A relief hole 22c is formed in the circuit board 22, and a push button switch 24 is mounted on the opposite side of the relief hole 22c from the rotary encoder 1 so as to face the rotary encoder 1. The push button switch 24 includes an actuator 25 a provided on a main body 25 connected and fixed to the circuit board 22.
A coil spring 26 is attached to one end of the main body 25. As shown in FIG.
Is formed.

A disc-shaped operating body 28 is disposed between the rotary encoder 1 and the push button switch 24, and a part thereof is located in the escape hole 22c.
The operating shaft 29 having a hexagonal cross section corresponding to the hole 12 of 0
It penetrates and is fixed to the central part of the operating body 28, and both ends thereof are fitted into the hole 12 of the rotating member 10 and the long hole 27 a of the push button switch 24, respectively, and rotate integrally with the operating body 28 and the rotating member 10. It is supported so as to be tiltable only in the vertical direction (arrows B and C directions) of the long hole 27a with the small diameter portion 12b (the rear end of the tapered portion 12a) of the rotating shaft 11 as a fulcrum.

A bush 3 is provided at one end of the operation shaft 29.
0, the coil spring 26 and the actuator 25a contact the bush 30 to hold the operating shaft 29 in parallel with the circuit board 22. As in the prior art, the bush 30 is connected to the main body of the push button switch 24. 25 and a distance H, and the distance between one end of the main body 25 and one end of the rotating shaft 11 of the rotating member 10 is set to a distance L1.

When the operator rotates the operating body 28 with his / her fingers, the projection 16b of the moderating plate 16 is
The rotating member 10 rotates integrally with the operation shaft 29 in the same direction as the rotation of the operating body 28 while generating a click feeling by alternately elastically contacting the concave portion 15a and the convex portion 15b. Accordingly, the three sliding pieces 14a and the plurality of conductive portions 8 come into contact with and separate from each other to generate a pulse signal. The pulse signal is used as a rotation amount detection signal of the operating body 28 at the terminal 5,
The signals are output from 6, 6 and input to the circuit board 22.

When the operator presses the operating body 28 with his / her finger, the operating shaft 29 has one end where the bush 30 is fitted around the small diameter portion 12b (the rear end of the tapered portion 12a) of the rotating shaft 11 as a fulcrum. In the direction indicated by arrow C, the bush 30 is lowered by the distance H against the resilience of the coil spring 26 and tilts, and the bush 30 presses the actuator 25a of the push button switch 24 to turn on the push button switch 24 as shown in FIG. , OFF, and the ON / OFF signal of the push button switch 24 is input to the circuit board 22. At this time, the small-diameter portion 12b of the rotating shaft 11 serving as a tilting fulcrum is located on a side of the one end of the rotating shaft 11 opposite to the push button switch 24 and further away from the one end of the rotating shaft 11 by a distance L2. Since the stepped portion 12d is provided and the inclination of the tapered portion 12a is set to about 3 ° as described above so that the inclination of the operation shaft 29 is not hindered by contact with a portion other than the small-diameter portion 12b of the rotary shaft 11, the rotary While the arrangement relationship between the encoder 1 and the push button switch 24 is the same as that of the prior art, the inclination angle θ of the operation shaft 29 is
1 is tan ^-1 (distance H ÷ (distance L1 + distance L2)), which can be made smaller than the inclination of the prior art, and the other end of the operation shaft 29 is received by the tapered portion 12a to stabilize the inclined operation shaft 29. I can support it.

Therefore, when the operating shaft 29 is tilted, FIG.
As shown in the figure, the small diameter portion 12b of the rotating member 10 and the operating shaft 2
9, an upward force F1 and a downward force F2 are generated at the contact point with the other end, respectively. The magnitude of the upward force F1 and the downward force F2 is smaller than that of the prior art because the inclination of the operation shaft 29 is small. Since the reaction force of these forces F1 and F2 received by the operation shaft 29 becomes small, the operation shaft 29 can be tilted smoothly. In addition, since the upward and downward forces F1 and F2 can be kept small, the moment in the direction of arrow A applied to the rotary encoder 1 decreases, and the amount of tilt of the rotary encoder 1 in the direction of arrow A decreases. , 6, 7 and the circuit board 22 (the portion to which the solder 23 is attached) can be reduced. In addition, since the inclination of the operation shaft 29 is small, the diameter of the large-diameter portion 12c of the rotation shaft 11, which is provided to avoid contact with the operation shaft 29, can be reduced. Encoder 1
Can be reduced in size. Further, since both the hole 12 of the rotating member 10 and the operation shaft 29 fitted into the hole 12 are regular hexagons, the tilting operation of the operation shaft 29 can be smoothly performed at any rotation angle position of the rotation member 10. You can do it.

Further, the operating shaft 29 is engaged at the central portion of the rotating member 10, and the operating shaft 29 is moved in the radial direction by about (L3 / 2) tan θ1 near both the open ends of the hole 12. In this sense, the diameter of the large-diameter portion 12c of the rotary shaft 11 provided to avoid contact with the operation shaft 29 can be made smaller than in the past. 1 can be reduced in size. The small-diameter portion 12a is formed with a flat surface to ensure the fitting with the operation shaft 29. Therefore, the rotating member 10 tends to tilt as the operation shaft 29 tilts. However, in the present embodiment, the operation shaft 29
Is engaged at the center of the rotating member 10 in the direction of the rotation axis R, and abuts on the bearing via the rotating shaft 11 of the rotating member 10.
Thus, the damage to the supporting portion of No. 0 can be suppressed.

As shown in FIG. 18, the rotary encoder 1 is tilted in the direction of arrow A by tilting the operation shaft 29. At this time, the rotary encoder 1 has the protrusion 16b of the moderating plate 16 Since the rotary member 10 is fitted into the concave portion 15a of the radial uneven portion 15, the contact portion P3 between the extended portion 18e formed integrally with the rear wall 18 of the mounting plate 17 and the circuit board 22 does not rotate. Is tilted smoothly with the fulcrum as a fulcrum, and a gap t is formed between the circuit board 22 and the clearances 5 of the three terminals 5, 6, 7.
a, 6a and 7a are reduced from the natural length S1 to the reduced length S2 to absorb the tilt amount of the rotary encoder 1. As a result of this absorption, the load applied to the connection portions between the terminals 5, 6, 7 and the circuit board 22 due to the tilt of the rotary encoder 1 is eliminated, and the connection state between the terminals 5, 6, 7 and the circuit board 22 is improved. Can be maintained.

When the operator stops pressing the operating body 28, the operating body 28 and the operating shaft 29 return to the state before the pressing (in the direction of arrow C) by the resilient force of the coil spring 26, and the terminals 5, 6 , 7 allow the rotary encoder 1 to return to the state before pressing (the direction opposite to the arrow A) due to the resilient force of the margins 5a, 6a, 7a. Thus, the rotation amount detection signal of the operating body 28 input to the circuit board 22 and the push button switch 24
Are turned on and off by a CPU (not shown) on the circuit board 22.
After the calculation is performed, the data is input to a display device (not shown), and control such as screen scrolling and a cursor on a display (not shown) is executed.

In this embodiment, the detection member 20 is provided on the rotating member 10 and the detection member 9 is provided on the support member 2.
The detecting member 9 may be provided on the rotating member 10 and the detected object 20 may be provided on the supporting member 2. In this embodiment, a pulse signal generating unit that generates a pulse signal by rotation of the rotating member 10 is slid. Although the present invention is configured by a combination of the detection target 20 including the moving element 14 and the detection target 9 including the plurality of conductive portions 8, the present invention is not limited to this. It is also possible to configure a combination of a slider and a resistor such as a variable resistor or a combination of a magnet and a Hall element.
