According to one or more embodiments, a sheet conveying device includes a reading device, a roller, a downstream guide, and a transition guide. The reading device reads a surface of the sheet. The roller faces the reading device. The downstream guide is downstream of the roller in the sheet conveyance direction. The transition guide guides the sheet at least during a sheet transition from the reading position to s an upstream end of the downstream guide.

A cutting plotter includes a driving roller, a rotating shaft, pinch rollers, a cutter, and a press roller. The driving roller extends in a direction of a first axis and rotates around the first axis. The rotating shaft extends in a direction of a second axis parallel to the first axis, and is configured to be rotatable around the second axis. A passage through which a cutting target passes is formed between the driving roller and the rotating shaft. The pinch rollers are provided on the rotating shaft. The cutter is selectively pressed to the cutting target. The press roller is provided on the rotating shaft between the pinch rollers, and presses the cutting target against the driving roller. The press roller is formed by a coil spring into which the rotating shaft is inserted.

Web guides including a roller, a control surface assembly, and a fin actuator. The roller is configured to mount to a drive shaft. The roller includes a tube wall. The tube wall defines an interior space, an exterior surface, and slots. The slots are circumferentially spaced around the tube wall. The slots pass through the tube wall from the interior space to the exterior surface. The control surface assembly is disposed within the interior space. The control surface assembly includes fins. The fins are aligned with the slots and adapted to selectively move between a retracted position contained within the roller and an extended position protruding beyond the exterior surface of the roller. The fin actuator is configured to selectively move the fins between the retracted position and the extended position.
