<p>PURPOSE:To enable drawing of a sheet from a tray side by releasing a nip of a transfer roller device of a register device automatically when a sheet fed from a manual inserting tray is jammed in a register device. CONSTITUTION:In an image forming device, a manual inserting tray is provided at the side of an image forming device main body to feed sheets to an image transfer section by merging to a sheet feed path from a main body sheet feed section. In a register device positioned just before the image transfer section, a mechanism to separate and contact a pinch roller 25 of a transfer roller device 15 with a drive roller 21 is provided. When any jamming is produced in the register device, a solenoid 32 is energized to raise a pinch roller 25 using an arm member 30, and nip of sheets is released to form a clearance between two rollers so that the sheet can be drawn from the manual inserting tray side.</p> |
