554362 A7 ____ B7 V. Description of the invention (2) The above-mentioned conventional rotary pulse switch is provided with an A-phase contact pattern, a B-phase contact pattern, and a general electrode pattern on one surface (graphic surface) of the substrate. If these three patterns are arranged on the same circumference, the diameter of the pattern surface will increase. Therefore, it has been difficult to achieve the required miniaturization. In addition, in order to accurately set the phase difference between the A-phase signal and the B-phase signal, it is necessary to accurately determine the relative positional relationship of the three patterns on the same surface. Therefore, there is also a case where a metal plate is formed by insert molding. When the individual patterns and the substrate form a whole, complicated position alignment work must be performed, which reduces the problem of operating efficiency. Furthermore, if the contact patterns and the general-purpose electrode patterns are arranged in a concentric circle shape on one surface of the substrate, the pattern surface diameter is significantly increased, which is not suitable for miniaturization. The present invention has been made in view of the actual situation of such a prior art, and an object thereof is to provide a rotary pulse switch suitable for miniaturization and easy to manufacture. Means for Solving the Problem In order to achieve the above object, the rotary pulse switch of the present invention includes: a second substrate provided with an A-phase contact pattern and a B-phase contact pattern; a second substrate provided with a universal electrode pattern; and The slider supports a movable body on a freely rotating drive shaft, and the slider is sandwiched between the first substrate and the second substrate, so that the slider is always kept in contact with the universal electrode pattern. The contact portion provided on the slider can be brought into sliding contact with the above-mentioned A-phase and B-phase contact patterns and can be separated. The rotary pulse switch constructed in this way can be used because the A-phase and b-phase contact patterns and general electrode patterns are set on different substrates and face each other, so -5-This paper size applies the Chinese National Standard (CNS ) A4 size (210X297mm) '~

Reducing the diameter of the pattern surface of each substrate facilitates miniaturization of the entire switch. In addition, it is not necessary to align the A-phase and B-phase contact patterns and the general-purpose electrode pattern on the same plane, and only the relative positional relationship between the A-phase contact pattern and the B-phase contact pattern can be considered, so the graphic surface is easy Formation operations. In the above structure, the slider has a mounting portion fixed to the drive shaft, and a pair of wrist portions protruding from the mounting portion toward the first substrate side and providing the contact portion on the protruding end portion. When the pair of wrists is set in a symmetrical positional relationship with the drive shaft as the center, the two contact portions of the pair of wrists that are in elastic contact with the first substrate will always be arranged around the drive shaft in a balanced manner. The shaft is not easy to tilt with respect to the first substrate, and can operate in a constantly stable state. At this time, as long as the slider is set to have a pair of protrusions, the protrusions protrude toward the second substrate side near the mounting portion, and often come into contact with the general electrode pattern, and the pair of protrusions are symmetrical about the drive shaft as a center. The positional relationship is preferable because the contact state between the slider and the second substrate is also stable. Furthermore, in the above-mentioned structure, a circular-cylindrical operation knob provided by the operator for turning operation, and the drive shaft is connected to one end side in the axial direction of the operation knob, which is advantageous for achieving a miniaturized rotary pulse switch.

Thereby, the rotary pulse switch 6 and the combination body 22 (the frame body 2 and the click mechanism part 3) are assembled to the entire movable part of the composite operation type electronic part on both ends of the operation knob 5 to allow a state of shaking Is held on the mounting plate 1 so that the protrusions 2 C and 2 d can move up and down in the coupling holes 1 b and 1 c. The operation of the composite operation type electronic component configured as described above will be described below. Now, if the operator performs the turning operation on the operation knob 5, the entire driving shaft 14 is rotated by clicking the shaft body 4. Therefore, the contact points 17 a, 1 8 a and A in the slider 15 are in contact with each other. 1 〇a And the Japanese phase contact pattern 丨 〇b for contact or separation.

For example, as shown in the same figure (a), the contact portions 17 a, 1 8 a and any of the contact patterns 1 0 a,! 〇 When neither b is in contact, neither the A-phase signal nor the B-phase signal is output. However, if the slider 15 is rotated to the position shown in the same figure (b), although the contact portion 17a is not in contact with any of the contact patterns 103 and 10b, the contact portion 18a will be in phase A. The contact pattern 10a is in contact, so the contact pattern i0a and the general-purpose electrode pattern 13 are turned on, and only the output of the a-phase signal is switched from "separated," to "connected."

When the slider 15 is further rotated to reach the position shown in the same figure (c), the contact portion 17a is in contact with the B-phase contact pattern 10b, and the contact portion 18a is still in contact with the A-phase contact pattern 10a. Therefore, the output of the a-phase signal remains on, and the output of the B-phase signal is also switched from "separated," to "on,". When the slider 15 is further rotated to reach the position shown in the same figure (d), the contact portion 17a remains in contact with the B-phase contact pattern 10b, but the contact portion 18a leaves the A-phase contact pattern. 10a, so the output of the a-phase signal is switched from ON to "separated", and the output of the B-phase signal remains on. In addition, if the slider 15 further rotates and reaches the position shown in the same figure (e), the contact portion 17a leaves the B-phase contact pattern 101), and the contact portion 18a is not in contact with any of the contact patterns 10. Phases a and 10b are in contact, so the output of phase a and phase B signals is turned off again. Thereafter, the same on and off are repeated as the slider 15 linked with the operation knob 5 rotates. Therefore, a rectangular wave is output from the a-phase signal and the 6-phase signal with a predetermined phase difference, and the rotation angle (rotation amount) and the rotation direction of the operation knob 5 can be measured based on the pulse signal. In addition, on the flange portion 4 a of the click shaft body 4, six click cam peaks 4 b corresponding to the respective contact patterns 丨 0 a and 丨 0b are formed, and the output of the phase A or phase B signal is performed every time.
