Abstract
A roll sheet conveying device includes a spool arranged to be rotatable while holding a roll-shaped sheet, a sheet conveying roller for driving and conveying the sheet, and a spool brake mechanism for generating a rotation load to act on the spool, wherein, when the sheet is sent out from the spool by driving the sheet conveying roller, the rotation load of the spool brake mechanism is caused to act on the spool, and when the sheet is rewound onto the spool by driving the spool, the rotation load of the spool brake mechanism is prevented from acting on the spool.
