To provide a method by which a circuit controller is improved for an adjustment of a user adjustable part of the device to be more readily adjusted than conventional about a position detecting cam of the circuit controller included in a railroad crossing blockade unit.SOLUTION: In a railroad crossing blockade unit 100 which has a blockade rod holding part (15), a motor (31), a main shaft (12), a driving mechanism for a drive (32), a driving mechanism for a detection to transfer an axle rotation of the main shaft (12) to a follower shaft (53, 73), a detection part (60) provided with plural position detection cams 61 to 66 installed in the follower shaft, a control part (40) to control rotations of the motor (31) in response to a rotation position detecting signal of the main shaft (12) by a train entering signal (TER) and position detection cams 61 to 66 and a housing 11 including the driving mechanism for a detection 50 and the detection part (60), the plural position detection cams 61 to 66 are arranged in left and right sides of the main shaft 12 seen in an axial direction of the main shaft 12 and among them, the upper and lower positions detection cams 61, 62 are together arranged in one side of the main shaft 12 and the other cams 63 to 66 are arranged in the other side of the main shaft 12.SELECTED DRAWING: Figure 1
【課題】踏切しゃ断機に内蔵されている回路制御器の位置検出用カムのユーザ調整可能部分に係る調整が現状よりも気軽に行えるように回路制御器を改良する。【解決手段】遮断桿保持部(15)と、モータ(31)と、主軸(12)と、駆動用伝動機構(32)と、主軸(12)の軸回転を従動軸53,73に伝達する検出用伝動機構と、従動軸に装着された複数の位置検出用カム61~66を具備した検出部(60)と、列車入信号(TER)と位置検出用カム61~66による主軸(12)の回転位置検出信号とに応じてモータ(31)の回転を制御する制御部(40)と、検出用伝動機構50や検出部(60)を内蔵する筐体11とを備えた踏切しゃ断機100について、複数の位置検出用カム61~66を主軸12の軸方向から見て主軸12の左右に分けて配設し、そのうち上下位置検出用カム61,62は共に主軸12の一方に位置させ、他のカム63~66は主軸12の他方に位置させる。【選択図】 図1
