<p><P>PROBLEM TO BE SOLVED: To solve problems in a conventional high-cost door driving device in which a power transmission system is complicated because a door shaft is installed vertically while a motor shaft is installed horizontally. <P>SOLUTION: In this door driving device for an automatic ticket gate using a motor as a driving source and opening/closing the door attached to the door shaft by turning the vertically arranged door shaft by 180°, the motor shaft 45 for the motor 32 is arranged in parallel to the door shaft 24, and a belt transmission mechanism 40 having a timing belt 43 extending perpendicular to the door shaft 24 is arranged in the power transmission system connecting the motor shaft 47 and the door shaft 24 together. As the motor shaft is arranged in parallel to the door shaft, the both shafts can be connected together by means of the simple belt transmission mechanism, and consequently, cost for the power transmission system part can be lowered. The motor shaft and the door shaft arranged in parallel to each other are connected together by a belt transmission mechanism. The belt transmission mechanism is constructed of a pair of pulleys and the timing belt suspended between them, and can be operated without any oil supply. Therefore, the belt transmission mechanism can be continuously operated even if the inside of the main body casing is contaminated by dust or waste. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
