摘要： It is an object of the present invention to prevent a sheet of continuous-form paper from slackening when it is fed back in a printer capable of feeding both sheets of continuous-form paper and cut-form paper. According to the method for feeding back a sheet of continuous-form paper (6) of the present invention, in a paper feed unit including a pin feed device (7) arranged in an upstream of the continuous-form paper feed passage and also including a friction feed device (4, 5) in which both the pin feed device (7) and the friction feed device (4, 5) feed the sheet of continuous-form paper (6) and a circumferential speed of the friction feed device (4, 5) is a little higher than that of the pin feed device (7), a first amount of feed is set by which the sheet of continuous-form paper is not loosened between the friction feed device (4, 5) and the pin feed device (7) and also a second amount of feed is set which is larger than a difference between an amount of feed of the friction feed device (4, 5) and an amount of feed of the pin feed device (7) when the sheet of continuous-form paper is fed back by the first amount of feed, and the sheet of continuous-form paper is fed back by the first amount of feed when both the friction feed device (4, 5) and the pin feed device (7) are simultaneously reversed, and the friction feed device (4, 5) is normally rotated by the second feed amount under the condition that the pin feed device is stopped. The sheet of continuous-form paper (6) is fed back by repeating the above reverse and the normal rotation.

摘要： A paper feed unit having a paper tray or hopper where recesses or windows are formed on a bottom surface of the tray upon which the sheets of paper will rest. The recesses are at positions which can correspond to the positions of a plurality of roller pieces mounted on a roller shaft thereabove. The recesses enable the pressing force of each roller piece of the roller against the upper surface of the uppermost sheet of paper to be uniform.
