A target transport apparatus includes a transport roller pair that has a plurality of segmented roller members disposed at intervals in a width direction that intersects with a transport direction of continuous paper and that imparts a transport force on the continuous paper by the segmented roller members pinching the continuous paper; and an image capturing unit, disposed in a location that corresponds to a pinched area in the width direction of the continuous paper that is pinched by the segmented roller members and to the pinched area along the transport direction, that detects, without making contact with the continuous paper, an amount by which the continuous paper is transported by the transport roller pair.

Target transport apparatus and liquid ejecting apparatus

After the control section of a printer (liquid discharge apparatus) discharges ink on the basis of a print job, the control section waits for an input of the next print job while causing the discharge section to perform flushing. If the next print job is input before the elapsed time Te from the end of the ink discharge on the basis of the print job exceeds the waiting time Tw, the control section causes ink to be discharged on the basis of the next print job. On the other hand, if the next print job is not input before the elapsed time Te exceeds the waiting time Tw, the control section causes the cap to be subjected to capping.

Liquid discharge apparatus

A transportation apparatus includes a transportation section that transports continuous paper in a transportation direction intersecting with a shaft direction of a transportation roller. An imaging section includes plural photoreceptor elements and captures an image of the continuous paper transported by the transportation section. The photoreceptor elements are arranged in a first direction and a second direction, the first direction intersecting with the shaft direction, and the second direction intersecting with the first direction. A transportation amount acquisition section acquires a transportation amount of the continuous paper in the transportation direction on the basis of the image captured by the imaging section. 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.

Transportation apparatus, printing apparatus, and transportation amount acquisition method

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.

Printing apparatus

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.

Transport device and printing apparatus

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.

Transportation device and recording apparatus

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 target transporting device includes a pair of transport rollers that applies a transport force to a continuous-form sheet toward a downstream side from an upstream side while pinching the continuous-form sheet; a guide member that applies a tension force to the continuous-form sheet being pinched by the pair of transport rollers toward the upstream side in a transport direction of the continuous-form sheet; and an image capturing unit that is disposed at a location upstream of the pair of transport rollers on a transport path of the continuous-form sheet so as to detect a transport amount of the continuous-form sheet to which the tension force is being applied by the guide member without contact.

Target transporting device and liquid ejecting apparatus

A pair of transportation rollers is configured such that a transportation driven roller is disposed at a position which is displaced downstream with respect to a position vertically above a transportation driving roller and feeds out the paper sheet guiding in obliquely downward direction. The entering direction of the paper sheet fed out from the pair of transportation rollers is determined so as to intersect the plane of the holding surface of the support table. A translucent glass that serves as a detection window of an imaging unit disposed at a position opposite to the paper sheet with respect to the holding surface is located downstream in the transportation direction with respect to an intersection position between the entering direction of the paper sheet and the holding surface. Specifically, the translucent glass is located in the proximity of an abutment position where the paper sheet abuts against the holding surface.

Medium transportation device and recording apparatus

A transportation device includes a transportation unit that transports a transportation target material, a supporting surface that supports the transported transportation target material, a first suction hole that opens in the supporting surface in order to suck the transportation target material which is supported by the supporting surface, a light transmission portion that is exposed in the supporting surface and through which light is permitted to pass, a detector that has a light irradiator capable of irradiating the transportation target material which is supported by the supporting surface with light through the light transmission portion and detects a transportation amount of the transportation target material based on reflected light of the light with which the light irradiator has irradiated the transportation target material, and a second suction hole that opens in the supporting surface at least one of the positions adjacent to the light transmission portion.

The invention provides a transportation apparatus for transporting a transportation target medium in a predetermined transportation direction. The transportation target medium transportation apparatus according to an aspect of the invention includes: a transport driving roller that is operated rotationally; a transport driven roller that is urged against the transport driving roller and follows the rotary movement of the transport driving roller; and a control unit that controls the movement of the transport driven roller between a contact position at which the transport driven roller is in contact with the transport driving roller and a non-contact position at which the transport driven roller is not in contact with the transport driving roller. In such a configuration of the transportation target medium transportation apparatus, the control unit moves the transport driven roller to the non-contact position at which the transport driven roller is not in contact with the transport driving roller when the thickness of the transportation target medium is at least a predetermined value, and then moves the transport driven roller to the contact position at which the transport driven roller is in contact with the transport driving roller when the length of time period in which the transport driven roller continues to be at the non-contact position exceeds a predetermined time period.
