Abstract
A detection device includes: a transport unit that stops transportation of a medium on which a first image is formed, the transport unit restarting the transportation of the medium toward an image forming unit after the medium has been in a stopped state, the image forming unit forming a second image on the medium; and a detection unit that detects an edge portion of the medium while the medium is in the stopped state.
Claims20
A detection device comprising:
- a transporter that stops transportation of a medium on which a first image is formed, the transporter restarting the transportation of the medium toward an imager after the medium has been in a stopped state, the imager forming a second image on the medium;
- and
- a detector that detects an edge portion of the medium while the medium is in the stopped state,
- wherein the transporter stops the transportation of the medium in a predetermined transporting direction, and
- wherein the detector includes:
- a pair of sensors, each sensor sensing one of a downstream edge portion and an upstream edge portion of the medium in the predetermined transporting direction;
- and
- a sensor positioned between the pair of sensors in side view and sensing a side edge portion of the medium.
