<p><P>PROBLEM TO BE SOLVED: To solve problems of a conventional high-cost door driving device requiring periodical dust removing and greasing work of a motor power transmission system component and having a complicated power transmission system. <P>SOLUTION: In this automatic ticket gate door driving device, a bevel gear set 24 converting horizontal power from a lateral motor 21 into vertical power is surrounded by a sealing case 42, and for rotationally opening/closing a door shaft 29 arranged in parallel to an output shaft 24 of the bevel gear set 24, a crank mechanism 34 is constructed of a driving lever 28 attached to a driven shaft 27 connected via a coupling to the output shaft 25, a driven lever 30 attached to the door shaft 29, and a coupling rod 31 installed between both levers. In this way, a manufacturing cost and a maintenance cost for the automatic ticket gate door driving device can be lowered. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
