Figure 10b touches and leaves. Bo Yue * Zhou Dandan Sliding Contact Hull-11-This paper size applies Chinese National Standard (CNS) A4 (210X 297 mm) 554364 A7 B7 V. Description of the invention (9) 1 5 for dogs 1 6 a, 1 6 b is always in contact with the common electrode pattern 1 3. The A-phase contact pattern 10a and the B-phase contact pattern 10b on the first substrate η form a pattern shape as shown in FIG. 13 'for example, as shown in the figure (a), in the contact portion 7a, 1 仏In a state where neither of the contact patterns 10a and 10b is in contact, the output of both the a-phase signal and the β-phase signal is turned off. However, when the sliding contact 15 is rotated to the position shown in the figure (b), the contact portion 17a does not contact the contact patterns 10a and 10b. However, since the contact portion 18a is in phase A The contact pattern 10a is in contact, so the contact pattern 10 & and the common electrode pattern 1j are conducting, but the output of the A-phase signal is switched from off to on. When the sliding contact 15 rotates again and reaches the position shown in the figure (c), the contact portion 17a is in contact with the B-phase contact pattern i0b, while the contact portion 18a is still in contact with the a-phase contact pattern 10a.
