A block diagram showing the transfer control circuit, and FIG. 4 is a time chart in FIG. 3. In the figure, 1a and 1b are side frames, 2 is a line feed motor, 3 is a platen, 9a and 9b are second sprocket wheels, 10a and 10b are first sprocket wheels, 11 is a micro switch, and 12 is a plunger. Magnet 15 indicates a bale roller.

Claims

[Scope of utility model registration request]

(1) A platen, a paper transport mechanism that supplies printing paper to the platen, a bail roller that rotates in contact with the surface of the platen to bring the transferred printing paper into contact with the printing area on the platen surface, and a platen. a drive source that swings the bail roller between a first position in contact with the surface of the platen and a second position away from the surface of the platen, and a drive source provided downstream of the paper transport mechanism in the paper transport direction, a paper detecting section that detects the leading edge of the paper being moved by the paper transport mechanism, and when the leading edge of the paper is detected by the paper detecting section, the bail roller is positioned at a second position by the drive source. Further, after the paper is transferred by a predetermined amount from the time of the detection, the drive source positions the bail roller at the first position to bring the transferred paper into contact with the surface of the platen. Automatic setting mechanism.

(2) The drive source moves the bail roller from the second position to the first position.
The automatic sheet setting mechanism in a printer according to claim 1, wherein the automatic paper setting mechanism is controlled so as to temporarily return to the second position in the process of swinging to the second position.
