PROBLEM TO BE SOLVED: To enable a recording action to be always correctly performed on a roll sheet by controlling the action of each of parts based on the detection results by a sheet type-detection mechanism for detecting the type of a roll sheet by the position of a flange contact member, and a sheet presence-detection mechanism and a sheet tip detection mechanism. SOLUTION: When a web 6 consisting of the desired various types of roll sheet 6a is loaded on a web retaining mechanism, a sliding table on a sheet type detection mechanism 11 is moved and the contact face of a flange contact member 17 is pressed into contact with the outer peripheral edge of a flange 6c. Further, three photosensors are turned ON/OFF in accordance with a stop position for the sliding table under a state in which the contact face of the flange contact member 17 is pressed into contact with the outer peripheral edge of the flange 6c. In addition, the type of the sheet is detected depending upon the combination of the three photosensors. CPU entering an output signal from a sheet presence detection mechanism 36 and a sheet tip detection mechanism 41, in addition to an output from the sheet type detection mechanism 11, controls the action of a printer and an image process based on the results of interpreting the type of the sheet, its presence and detecting the tip of the sheet. |
