A liquid ejecting apparatus includes an ejecting unit which can eject liquid in an ejecting region: and a medium support unit which can support a medium on a downstream side in a transport direction of the medium compared to the ejecting region, in which the medium support unit has a first region which has at least one face, and a second region which is located between the ejecting region and the first region, and has a plurality of bent portions, and in which the length of a face between the bent portions in the second region in the transport direction is shorter than the length of a face included in the first region in the transport direction.

Liquid ejecting apparatus

A liquid ejecting apparatus includes a heating unit; a detecting unit capable of detecting the energies of plural detection areas in a heating area to be heated by the heating unit; and a controller that controls the heating unit on the basis of the energies of the plural detection areas detected by the detecting unit. The controller controls the number of detection areas which are used in control of the heating unit in a case where a medium has been transported to a position where the medium overlaps with at least one of the plural detection areas so that the number is larger than the number of detection areas which are used in the control of the heating unit in a case where a medium has been transported to a position where the medium does not overlap with at least one of the plural detection areas.

Liquid ejecting apparatus and heating unit control method

A liquid discharge apparatus includes a support portion that supports a sheet that is transported and a discharge unit that includes a carriage that is freely movable in scanning directions that intersect with a transport direction of the sheet and a liquid discharge head that is mounted on the carriage and that discharges ink to the sheet. End portions of the discharge unit in the scanning directions are provided with a plurality of ribs that are protruded along the scanning directions and that are provided so as to be juxtaposed with intervals in the transport direction. The ribs press a bend of the sheet toward the support portion as the carriage moves along the scanning directions.

Liquid discharge apparatus

A liquid discharging apparatus includes a head that discharges a liquid onto a medium, a medium supporting portion that supports the medium, a heater that heats the medium supported by the medium supporting portion, and a detecting unit that performs sensing and detects energy. The radiation energy of the heater is controlled on the basis of the energy detected by the detecting unit. The medium supporting portion is provided with a sensing target portion that can be sensed by the detecting unit.

A liquid discharging apparatus includes a discharge unit that is capable of discharging a liquid, a heating unit that is capable of heating a medium onto which the liquid is discharged, a detection unit that detects an energy that is emitted from a detection range, a control unit that is capable of changing an output of the heating unit on the basis of an energy that the detection unit detects, and a sensing target portion, which has a sensing target surface from which an energy is detected by the detection unit, and the sensing target surface is processed in order to reduce mirror reflection of input light.

Liquid discharging apparatus and heating unit control method

A liquid discharging apparatus includes a discharge unit that is capable of discharging a liquid, a medium support unit in which an opening portion is provided, and which supports a medium onto which the liquid is discharged, a heater that is capable of applying heat to the medium, a sensor that detects an energy in a detectable region, a control unit that is capable of changing an output of the heater on the basis of the energy, and a detectable portion whose energy is detected by the sensor, and which is provided in a position that is within the opening portion and is within the detectable region.

A recording apparatus includes a sound pickup unit that is arranged on a plurality of spots, and an output unit that is capable of outputting comparative information between a sound which is picked up by the sound pickup unit, and each sound pickup unit at a time of picking up the sound. By the recording apparatus of such a configuration, a cause of an abnormality can be estimated, regarding the abnormality which is generated in the recording apparatus.

Recording apparatus and method for estimating cause of abnormality of recording apparatus

A recording apparatus includes a setting unit which sets a recording medium; a transport unit which transports the recording medium; a detection unit which is provided in a transport path of the recording medium and detects the recording medium; and a control unit which controls the transport unit. The transport unit includes a drive roller which is provided to be capable of contacting a first surface of the recording medium and applies a sending force to the first surface, and a blowing unit which is provided in a position opposing the drive roller and is capable of blowing onto a second surface of the recording medium. When the detection unit detects the recording medium, the control unit controls the transport unit so as to cause air to be blown from the blowing unit.

A medium holding member that is attached to a medium supporting portion includes a fitting portion that is fit into the medium supporting portion and that is located at each of at least one portion in an upstream side edge portion of the medium holding member in a medium transportation direction.

Medium holding member and recording apparatus

A medium supporting device includes a flexible medium supporting section that supports a medium, a supporting base that supports the medium supporting section in contact with a first contact section and a second contact section, and a tension applying section that applies tension to the medium supporting section between the first contact section and the second contact section. The first contact section and the second contact section extend in a cross direction, intersecting with the tension applying direction.

Medium supporting device and liquid ejecting apparatus

There is provided a recording apparatus including a movement unit that reciprocates while sliding along guide shafts and sound collection units that are disposed in the movement unit so as to collect a sound generated due to sliding of the guide shafts. According to the recording apparatus configured in this way, it is possible to perceive a change in a sliding state in the movement unit which reciprocates while sliding along the guide shafts.

Recording apparatus

A recording device includes a head unit that ejects ink onto a target recording medium, and transport units that transport the target recording medium. The transport units are provided with driving rollers that are provided so as to come into contact with a first surface of the target recording medium, and that generate a delivery power in the target recording medium, and air delivery units that push the target recording medium against the driving rollers by applying air pressure to the driving rollers from a side of a second surface of the target recording medium.

Recording device

A recording apparatus includes a transportation section that transports a recording target medium, and a control section that controls the transportation section. The transportation section includes a drive roller that is provided so as to be contacted with a first face of the recording target medium and that applies a forwarding force piece to the first face, and an air blowing section that is provided at a position opposite the drive roller and that blows air onto a second face of the recording target medium. The air blowing section performs an adjustment of an amount of air blown from the air blowing section itself under the control of the control section.
