A liquid ejecting apparatus includes: a liquid ejecting head that includes a nozzle surface on which a nozzle is open and that ejects a liquid through the nozzle; a housing that accommodates the liquid ejecting head; a moving mechanism that moves the liquid ejecting head relative to the housing in a moving direction intersecting the nozzle surface; and a duct in which a fluid flows, in which the duct includes a first coupling section coupled to the housing and a second coupling section coupled to the liquid ejecting head and is configured to expand and contract in the moving direction.

Liquid ejecting apparatus

A liquid ejecting device includes: a printing unit including a liquid ejecting head configured to eject a liquid to a medium and a head holder configured to form an air cooling path, and a cooling mechanism configured to cause air in the air cooling path to flow therethrough to air-cool the liquid ejecting head, wherein the printing unit is provided so as to be movable with respect to a transport path along which the medium is transported, the cooling mechanism includes a first air hole and a second air hole that are configured to be coupled to the air cooling path, and the air cooling path is coupled to one of the first air hole and the second air hole corresponding to a position of the printing unit.

Liquid ejecting device

A recording device includes a recording unit configured to perform recording on a recording target medium, a first conveyance path that is a conveyance path of the recording target medium including an opposite position that faces the recording unit, and conveyance of the recording target medium in a first direction, a second conveyance path being coupled to the first conveyance path at a position downstream of the recording unit in the first direction, the second conveyance path being coupled to the first conveyance path also at a position upstream of the recording unit in the first direction and configured for conveyance of the recording target medium to the first conveyance path with a surface of the recording target medium inverted, and an insertion port configured to enable insertion of a recording target medium as an insertion material to the second conveyance path from outside.

Recording device with front side insertion port

A control section of a recording apparatus is configured to execute control of overlapping transportation in which a preceding medium and a following medium are transported in a state in which a rear end region of the preceding medium and a leading end region of the following medium overlap at least in a partial section in an upper transport route, and determines an overlapping dimension Lk that is a dimension, by which the rear end region of the preceding medium and the leading end region of the following medium overlap, in accordance with a route dimension Ld from a third feed roller pair to an edge of an introducing port in a second direction, when executing the control of the overlapping transportation.

Recording apparatus

A recording apparatus includes a reverse path for reversing a surface of a medium, a second medium transport path for guiding the medium on which recording has been performed to the reverse path, a third medium transport path which is positioned vertically below the second medium transport path and guides the medium on which recording has been performed to the reverse path, in which a first path forming portion that forms the reverse path, a second path forming portion that forms a part of an upper side of the second medium transport path, and a third path forming portion that forms a part of an upper side of the third medium transport path are constituted to be attachable and detachable as a unit body, and a part of the second medium transport path and a part of the third medium transport path are exposed by removing the unit body.

A recording apparatus which is capable of suppressing or avoiding a concern on a defect such as a paper jam, deterioration of recording quality, or the like at the time of performing an overlapping transportation is provided.

There is provided a printing device which can reduce the frequency at which a consecutive overlap-feeding operation is performed in a state where an overlap error in which a preceding medium and a following medium are overlapped in reverse order is not corrected.

Printing device

There is provided a printing device which can suppress a decrease in printing quality with respect to a following medium which is generated when performing a consecutive overlap-feeding operation of transporting a preceding medium and a following medium together to a printing start position of the following medium in a state where the preceding medium and the following medium partially overlap each other.

A printing device includes a printing unit, a pair of transporting rollers (a pair of rollers) that is disposed right before the printing unit and that transport a medium to the printing unit, and a transportation direction changing mechanism that is disposed on an upstream side of the pair of transporting rollers and that changes a transportation direction of the medium before the medium is nipped by the pair of transporting rollers. The transportation direction changing mechanism changes a transportation direction of a following medium such that a leading end portion of the following medium overlaps a preceding medium when the printing unit performs printing in a state where the preceding medium is nipped by the pair of transporting rollers.

A recording apparatus includes: a carriage that has a housing in which a recording head is provided; a guide member that guides the carriage; a gap adjusting unit that adjust a gap between the medium and the recording head; and a cap member by which the recording head is capped. The gap adjusting unit includes a sliding member that slides over the guide member, a cam member that is interposed between a part of the housing and the sliding member and has a shape with which the housing is caused to shift in the direction in which the gap is changed, by moving in the first direction relative to the housing and the sliding member, and a pressing member that presses the cam member to the housing of the carriage in a second direction intersecting with the first direction and the direction in which the gap is changed.

A liquid ejecting apparatus and a method for detecting a medium edge position are provided wherein the edge position of the medium can be comparatively more accurately detected even when the sensitivity of an optical sensor has changed due to fouling or the like.

Liquid ejecting apparatus and method for detecting medium edge position in liquid ejecting apparatus

To provide a liquid ejecting apparatus and a method for detecting a medium edge position in a liquid ejecting apparatus whereby a decline in the accuracy of detecting an edge position of a medium caused by fouling of an optical sensor can be minimized, a reference reflecting surface, used in order to acquire a sensitivity determination value for determining the timing of switching the sensitivity of a sheet width sensor provided to a carriage, is irradiated with light and the output voltage of a light-receiving unit receiving the reflected light thereof is acquired; the output voltage is subtract from a power source voltage to measure a reference surface voltage.

To provide a liquid ejecting apparatus and a method for detecting a medium edge position in a liquid ejecting apparatus, whereby the position of an edge of a medium can be detected while also avoiding an event where a protrusion present in a region targeted for detection by an optical sensor is erroneously detected as being the medium, a carriage is moved so as to traverse a sheet of paper in the width direction, and a determination is made as to whether or not an output voltage of a sheet width sensor provided to the carriage has crossed over a first threshold value.

This is to provide a liquid ejecting apparatus and a sensor sensitivity setting method in a liquid ejecting apparatus making it possible to keep low any fluctuations in the reflectance of a reflecting part used to measure the sensitivity of an optical sensor provided to a carriage, and to enhance the accuracy of measurement sensitivity, thus making it possible to ensure the required sensitivity even in spite of progressive deterioration of the optical sensor.
