<P>PROBLEM TO BE SOLVED: To enable a gate arm to smoothly and reliably respond to the detection of parking. <P>SOLUTION: A drive shaft 19 and a driven shaft 29 are rotatably supported at both upper and lower ends of a frame body 7. One end of a gate arm 21 that opens and closes an entrance of a parking base frame is supported by an end of the drive shaft 19 protruding from one side of the frame body 7 so as to be swung with the rotation of the shaft. The rear end of a lock plate having a lock hole at the center of the front end is attached to an anchoring collar part fastened to the center of the drive shaft 19. A support mechanism 40 that holds and releases the lock plate in an unlock position with the gate arm 21 rotated to a vertical direction is attached to a partition plate 11 fastened in the frame body 7. A lock mechanism that locks the lock plate in a lock position with the gate arm 21 rotated to a horizontal direction is attached to a support plate 12 perpendicularly fastened to one side of the partition plate 11. A parking detection sensor, the support mechanism 40 and the lock mechanism which are all fastened to one side of the frame body 7, a detection switch, and an accounting device are electrically connected so that the gate arm 21 is locked or unlocked. <P>COPYRIGHT: (C)2012,JPO&INPIT |
