Title (EN) SIGNAL TRANSMISSION CIRCUIT AND ENDOSCOPE
(FR) CIRCUIT DE TRANSMISSION DE SIGNAL ET ENDOSCOPE
(JA) 信号伝送回路及び内視鏡装置
Abstract:
(EN) A signal transmission circuit and an endoscope in which communication by a plurality of differential signals of different signal standards can be achieved through a simpler arrangement than before. The signal transmission circuit comprises a pulse transformer (52) including a primary winding consisting of coils (52a, 52b) connected in series and a secondary winding consisting of coils (52c, 52d) connected in series, a switch (53a) having one end connected with a predetermined potential and the other end connected with the joint of the coils (52a, 52b), a switch (53b) having one end connected to the ground side and the other end connected with the joint of the coils (52c, 52d), a pair of first signal lines being connected with the opposite ends of the primary winding, respectively, a pair of capacitors (54) being connected with the opposite ends of the secondary winding, respectively, and a pair of second signal lines being connected with the other end of the pair of capacitors (54), respectively.
(FR) La présente invention concerne un circuit de transmission de signal et un endoscope dans lesquels une communication par une pluralité de signaux différentiels de différentes normes de signaux peut être obtenue au moyen d'un agencement plus simple qu’avant. Le circuit de transmission de signal comprend un transformateur d'impulsion (52) comprenant un enroulement principal consistant en des bobines (52a, 52b) raccordées en série et un enroulement secondaire consistant en des bobines (52c, 52d) raccordées en série, un commutateur (53a) ayant une extrémité raccordée à un potentiel prédéterminé et l'autre extrémité raccordée au joint des bobines (52a, 52b), un commutateur (53b) ayant une extrémité raccordée à la terre et l'autre extrémité raccordée au joint des bobines (52c, 52d), une paire de premières lignes de signal raccordées aux extrémités opposées de l'enroulement principal, respectivement, une paire de condensateurs (54) raccordés aux extrémités opposées de l'enroulement secondaire, respectivement, et une paire de secondes lignes de signal raccordées à l'autre extrémité de la paire de condensateurs (54), respectivement.
(JA)  信号規格が各々異なる複数の差動信号による通信を、従来に比べて簡易な構成により可能とする信号伝送回路及び内視鏡装置を提供する。本発明の信号伝送回路は、直列接続されたコイル52a及びコイル52bにより構成された一次巻線と、直列接続されたコイル52c及びコイル52dにより構成された二次巻線と、を含んで構成されたパルストランス52と、一端が所定の電位に接続され、他端が上記コイル52a及び上記コイル52bの接続点に接続されたスイッチ53aと、一端が接地側に接続され、他端が上記コイル52cと上記コイル52dの接続点に接続されたスイッチ53bと、上記一次巻線の両端にそれぞれ接続する一対の第1の信号線と、上記二次巻線の両端にそれぞれ接続する一対のコンデンサ54と、上記一対のコンデンサ54の他端にそれぞれ接続する一対の第2の信号線と、を具備する。
