A sheet attaching apparatus includes a non-adhesive guide sheet for leading the peeled sheet to the attaching position while keeping away from the substrate; a stopper to which forward edges of the substrate and the sheet contact, movable between a position across the feed path and a position off the feed path; a movable press roller for pressing the forward portion of the sheet onto the forward portion of the substrate to attach the sheet onto the substrate at the attaching position; and a feed roller arranged facing the press roller and for discharging the adhered sheet and substrate from the attaching position. The guide sheet has slits extending in the feed direction at the forward portion. The press roller presses the forward portion of the sheet to the forward portion of the substrate through the slits so as to attach the sheet S onto the substrate.
