Title: Sheet conveying device
Inventor: TOMOE TETSUO
IPC: G03G15/20
Filed: 1992-07-13
Abstract: PURPOSE:To enable release of the pressure contact in a small force, as well as to form the device in a compact size, by releasing the pressure contact of two sheet conveying surfaces by the rotation of a cam member provided at the periphery of a rotary shaft. CONSTITUTION:In the condition that an imaging unit 11 is installed to the device, the tip of the lever part 65c of a pressure contact release lever 65 is abutted to the bottom surface of a unit case 30, and the lever part 65c is rotated clockwise against the energizing force of a spring 66. In such a condition, a cam 65b is separated from the bearing projection 62a of a pressure roller 51. As a result, the pressure roller 51 is brought into pressure-contact with a heat roller 50 by a spring 63. When the paper sheets generate a jamming at a fixing and conveying device 16 part, the bottom surface of the unit case 30 is separated from the front end of the lever part 65c by opening the upper case, and thereby, the pressure contact release lever 65 is rotated counterclockwise, the pressure roller 51 is separated from the heat roller 50 by pressing the cam 65b, and the paper sheets in the jamming can be picked out easily.
