Abstract
During the forward driving of a recording motor, a platen roller is forwardly rotated and a de-curl shaft is rotated so as to bear against a recording sheet and at this time, a cutter is not driven. During the reverse driving of the recording motor 31, the cutter 17 is first driven to cut the recording sheet 14, whereafter the platen roller 15 is reversely driven and the de-curl shaft 27a becomes spaced apart from the recording sheet 14.
Claims26
A recording apparatus, comprising:
- a conveying member for conveying a sheet;
- recording means for recording an image on the sheet conveyed by said conveying member;
- a cutter disposed downstream of said recording means for cutting the sheet conveyed by said conveying member;
- a drive source rotatable in a forward and a reverse direction;
- drive force transmitting means for transmitting a drive force to said conveying member during the forward rotation of said drive source, and transmitting the drive force to said conveying member after a predetermined amount of reverse rotation of said drive source so as to await cutting of the sheet by said cutter;
- a one-way clutch which does not transmit the drive force to said cutter during the forward rotation of said drive source, and transmits the drive force to said cutter to operate said cutter during the reverse rotation of said drive source;
- and
- curl correcting means to correct for curling of the sheet, including means for shifting said curl correcting means to an operating position in response to the forward rotation of said drive source to correct for curling of the sheet, and for shifting to a non-operating position in response to the reverse rotation of said drive source so as not to correct for the curling of the sheet.

A sheet conveying apparatus, comprising:
- a conveying member for conveying a sheet;
- a cutter for cutting the sheet conveyed by said conveying member;
- a drive source rotatable in a forward direction and a reverse direction;
- drive force transmitting means for transmitting a drive force to said conveying member during the forward rotation of said drive source, and transmitting the drive force to said conveying member after a predetermined amount of reverse rotation of said drive source so as to await cutting of the sheet by said cutter;
- an one-way clutch which does not transmit the drive force to said cutter during the forward rotation of said drive source, and which transmits the drive force to said cutter to operate it during the reverse rotation of said drive source;
- and
- curl correcting means to correct for curling of the sheet, including means for shifting said curl correcting means to an operating position in response to the forward rotation of said drive source to correct for curling of the sheet, and for shifting to a non-operating position in response to the reverse rotation of said drive source so as not to correct for the curling of the sheet.
