Abstract:
A roll sheet conveying device, comprising:a spool arranged to be rotatable while holding a roll-shaped sheet; sheet conveying means for driving and conveying the sheet; and load generating means for generating a rotation load to act on said spool, wherein, when the sheet is sent out from said spool by driving said sheet conveying means, the rotation load of said load generating means is caused to act on said spool, and when the sheet is rewound onto said spool by driving said spool, the rotation load of said load generating means is prevented from acting on said spool; and wherein said spool is arranged to hold a core member of the roll-shaped sheet, and further comprising control means for detecting whether or not a slip takes place between the sheet and the core member in at least one of sending out the sheet and rewinding the sheet for, upon detection of the slip, restraining driving of at least one of said sheet conveying means and said spool.
