PURPOSE:To enable a simply constituted paper feed equipment of absorbing moisture in sheets of paper and preventing malfunction by mounting a heater at a part of the stacking board of said equipment and using the current supply cable of said heater as insulators. CONSTITUTION:Sheets of paper P stucked on a tray 22 are delivered one by one from the top sheet by a feed roller 23 to a feed part 24. The elevation of the tray 22 is controlled according to the sheets of paper left on the tray 22 so that the top sheet always comes in the suitable position for the feed roller 23. If the tray 22 becomes empty or sheets of paper are jammed in the equipment, the tray 22 is lowered. A resistor 30 is attached to the lower face of the tray 22. The resistor 30 is supplied with voltage from a power supply circuit inside a base frame 27 to generate heat so that the tray 27 is heated to prevent the sheets of paper P from sucking moisture. A cable 29 which is elastic and flexible posses the insulator function. By preventing the sheets of paper from absorbing moisture, the generation of faulty image can be prevented. |
