<p>PURPOSE:To provide a paper feeder of a little feeding load without folding the front end of a decalcomania paper sheet by exciting a solenoid at a point where the front end of rite decalcomania paper sheet reaches a nip, thereby separating a bottom place from a feeding roller, and by canceling the abutting pressure between the paper sheet loaded on the bottom plate and the feeding roller. CONSTITUTION:A feeding cassette part mainly comprises a bottom plate, on which a plurality of decalcomania paper sheets 1 are loaded, the one end of which is crossed with a rotational shaft 2, and the other end of which is energized upward by a spring 3. A feeding roller 5 is arranged on the front end of the decalcomania paper sheer 1 so that the roller can be freely rotated and lifted/lowered, while a reverse roller 6 is arranged on the feeding roller 5 so that the reverse roller 6 can be abutted on the feeding roller 5. An armature of a solenoid 7 is mounted on the front end of the under surface of the bottom plate. When feeding is to be carried out, the feeding roller 5 and the reverse roller 6 are rotated, and only the uppermost one of the decalcomania paper sheets is fed by the frictional force of the feeding roller 5, and the uppermost one is sandwiched in a nip 9 and is thus fed out. A solenoid is driven after a specified period of time passes since the decalcomania paper sheet 1 is started to be fed, to separate the bottom plate from the feeding roller 5.</p> |
