らず、非常に煩わしい作業を行つていた。 However, with conventional automatic paper feeders, the range in which the platen can reverse itself while holding paper is limited to
Since the paper on the paper feed stacker is in pressure contact with the paper feed roller, it is possible to give the paper a slight deflection, and after the paper has been caught by the paper ejection roller, the platen must be reversed. It is not possible to backfeed the paper in the paper feeding direction, and it is not possible to backfeed the paper in the paper feeding direction. graph. For complex printing such as vertical text processing, operators had to insert sheets of paper into the platen one by one and print without using an automatic paper feeder, which was a very troublesome task.

の状態で印字を開始する。 When the print start signal is input, the solenoid 16
is excited and the paper feed roller 7 is brought into pressure contact with the paper p on the paper feed stacker 6, and then rotated by the driving means, the uppermost paper p is separated into one sheet by the separating claw 10, and is moved along the paper feed guide plate 17. transported.
Thereafter, when the leading edge of the paper is detected by the sensor 22 provided in the printing device, the plunger 20 of the solenoid 16 moves to position c after a predetermined period of time, and thereby the paper feed roller 7 is moved to the paper feed stacker 6. It is located at an intermediate position c, which is separated from the upper paper pressure contact feeding position. Further, the fed paper p is loaded onto the platen 3 by rotation of the platen 3. At this time, the time when the paper p is loaded onto the platen and the timing when the paper feed roller 7 is separated to the intermediate position are set to be approximately the same. Furthermore, the paper p is fed as the platen 3 rotates, and the paper p is fed to the next sensor 2.

ばよい。 In this embodiment, the paper feed roller 7 is placed at a position where it presses against the paper p on the paper feed stutter, at a position where it presses against the discharge roller 14, and at a position where it presses against the paper p on the paper feed stacker. Although the paper feed roller 7 was configured to be selectively positioned at an intermediate position where it does not touch any of the ejection rollers 14 and used as both the separation feed roller and the paper ejection roller, it is possible to use the paper feed roller 7 only as a separation roller. The ejection roller may be configured as a pair of rollers, each of which separates from the paper, and the roller that separates from the paper is the paper feed roller. It is not limited to the paper ejection roller; for example, a paper relay roller disposed at an appropriate position depending on the paper size may be configured so that it can be disengaged from the paper when the paper is loaded on the platen 3. In short, any configuration that allows the paper to move freely after the paper is loaded onto the platen 3 is sufficient.
