Abstract

PURPOSE:To stabilize the sending of papers by preventing the movement of a paper-feed shaft by a method in which gears energized by a coil spring are engaged with the paper-feed knob slidably with gears fixed to the tractor shaft of a paper feeding mechanism and the paper-feed shaft is separated from the knob. CONSTITUTION:When feeding papers manually, a knob 5 is pulled in the direction of arrow, whereupon a clutch projection 4A and a clutch recession 5A are opened and the transmission path from a motor 1 is opened. In this case, the knob 5 is fixed by a screw 16, and the knob shaft 7 set in parallel with the tractor shaft 7 slides on the inside of a hub 18 combined with a side plate 17. A gear 6 fixed to the other end of the knob shaft 7 is also slid together. When the knob 5 is turned under the condition, the feeding of papers can be performed under the condition that the motor 1 is separated. After the feeding of papers, when the knob 5 is separated, the clutched state is restored by a coil spring 20 between the side plate 17 and the gear 6.

、噛台数か少ないため、噛合が不確実であった。Conventional configuration and its problems Conventional printing devices transmit the rotation from the motor to a clutch built into the manual paper feed knob that is directly connected to one drive shaft of the paper feed tractor. In the above, when the clutch was released by operating the knob, the drive shaft that rotated the paper feed tractor supported by the printer side plate moved in the axial direction. This was because the centers of the shaft and bearing were not aligned and required a large amount of force to operate the knob, resulting in poor operability.Furthermore, the clutch diameter was small and the number of teeth was small, resulting in unreliable engagement.

The purpose of this is to eliminate the negative effect of paper feed on paper feeding and to improve clutch engagement by changing the clutch diameter.
