A transportation device includes: a transportation section that transports a continuous paper; and an imaging unit that detects a transportation amount of the continuous paper which is transported by the transportation section. The imaging unit includes a lens barrel; a light irradiation unit disposed in the lens barrel and capable of radiating light on the continuous paper; a condensing lens which is disposed in a position farther than the light irradiation section with respect to the continuous paper in the lens barrel and condenses a reflected light when the light is radiated from the light irradiation section to the continuous paper; and an imaging element which is disposed in a position farther than the condensing lens with respect to the continuous paper P in the lens barrel and captures an image by receiving the reflected light condensed by the condensing lens.

A printing apparatus includes a control unit that calculates a transport amount (an actual transport amount) during a transport period based on a captured image of a medium by an imaging unit and controls a transport unit. In addition, the control unit calculates the transport amount (the actual transport amount) during the transport period by calculating the transport amount at each calculation interval (a divided transport amount) and integrating the transport amount at each calculation interval (the divided transport amount). Then, the control unit causes the calculation interval to be longer in a case where the transporting speed of the medium is low than in a case where the transporting speed of the medium is high.

A transportation apparatus comprises: a transportation section that transports continuous paper in a transportation direction intersecting with a shaft direction of a transportation roller by operating the transportation roller; an imaging section that includes plural photoreceptor elements and captures an image of the continuous paper transported by the transportation section, the photoreceptor elements being arranged in a first direction and a second direction, the first direction intersecting with the shaft direction, the second direction intersecting with the first direction; and a transportation amount acquisition section that acquires a transportation amount of the continuous paper in the transportation direction on the basis of the image captured by the imaging section, wherein the transportation amount acquisition section acquires the transportation amount of the continuous paper by correcting a movement amount of the continuous paper in the first direction with a correction value that changes in accordance with orientation of the first direction.
摘要:
A printing apparatus includes a supporting member, a printing section, an image capturing section, and a receiver. The supporting member is configured to support a continuous form. The printing section is configured to cause ink to adhere to the continuous form supported by the supporting member, thus performing printing. The image capturing section is disposed in the supporting member, with a gap between the image capturing section and the supporting member. The image capturing section is configured to capture an image of the continuous form. The receiver is configured to receive ink. The receiver is disposed below the gap.
摘要:
A transportation device includes a transportation unit that transports continuous paper, and an image capturing unit that has a light irradiator capable of irradiating the continuous paper which is transported by the transportation unit with light and detects a transportation amount of the continuous paper based on reflected light of the light irradiated onto the continuous paper by the light irradiator. The light irradiator is arranged so as to irradiate the continuous paper with light obliquely with respect to the detection region of the continuous paper from the width direction side of the continuous paper, which is orthogonal to the transportation direction of the continuous paper.
