Abstract
전지의 삽입극성에 무관하게 항상 일정한 전압 극성을 세트에 공급하기 위한 전지 극성 자동절환 전환 공급회로는, 전지 케이스(12)의 제1 접속판(13)을 제1, 4스위칭 트랜지스터(Q1,Q2)의 각 베이스와 제 2,3 스위칭 트랜지스터(Q2,Q3)의 각 에미터에 공통으로 연결하고, 상기 전지 케이스(12)의 제2 접속판(14)을 제2,3스위칭 트랜지스터(Q2,Q3)의 각 베이스와 제1,4스위칭 트랜지스터(Q1,Q2)의 각 에미터에 공통으로 연결하여, 상기 제1,2스위칭 트랜지스터(Q1,Q2)이 공통 콜렉터에서는 +전압이, 상기 제3,4스위칭 트랜지스터(Q3,Q4)의 공통 콜렉터에서는 -전압이 출력되게 한다.The battery polarity automatic switching switching supply circuit for supplying a constant voltage polarity to a set at all times irrespective of the insertion polarity of the battery includes the first and fourth switching transistors Q 1 , Q 2 ) is commonly connected to each base of the second and third switching transistors Q 2 and Q 3 , and the second connection plate 14 of the battery case 12 is second and third switching. The first and second switching transistors Q 1 and Q 2 are connected in common to each base of the transistors Q 2 and Q 3 and the emitters of the first and fourth switching transistors Q 1 and Q 2 . The + voltage is output from the common collector and the-voltage is output from the common collector of the third and fourth switching transistors Q 3 and Q 4 .
