<p><P>PROBLEM TO BE SOLVED: To provide an original pressing plate opening and closing device for OA equipment, capable of being manufactured at lower cost by reducing the number of extra parts, thereby simplifying a configuration. <P>SOLUTION: The device includes: an attachment member having a cylindrical attachment leg part provided with a storage hole whose upper part is opened in the axial direction of the central part; a supporting member attached to both side plates provided in the upper part of the attachment member, turnably through a hinge pin; and a rotation control means provided between the supporting member and the attachment member. The rotation control means includes an elastic means comprising a compression coil spring stored in the storage hole of the attachment leg part; a roller provided in the supporting member, to face the elastic means; and a cylindrical spring guide attached between the roller and the compression coil spring, while the cylindrical spring guide covers the compression coil spring. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
