Abstract: There is provided an air conditioner capable of displaying sufficient cooling ability in each indoor unit by allowing a sufficient amount of refrigerant to flow into indoor units where cooling ability cannot be displayed. By executing refrigerant amount balance control, since degrees of opening of indoor expansion valves are narrowed in indoor units whose refrigerant superheating degrees are smaller than an average refrigerant superheating degree, amounts of refrigerant flowing into the indoor expansion valves are decreased. In the indoor unit where the refrigerant superheating degree is higher than the average refrigerant superheating degree, since refrigerant pressure on a downstream side of the indoor expansion valve is also decreased due to the degrees of opening of the indoor expansion valves being narrowed, the difference in pressure between the upstream side and the downstream side of the indoor expansion valve increases and an amount of refrigerant flowing into the indoor unit is increased.

Abstract: A liquid discharge apparatus includes a liquid discharge head including a discharge port configured to discharge liquid and a discharge port surface provided with the discharge port. A head cleaning member including a contact portion contacts the discharge port surface, and is configured to cause the contact portion to contact the discharge port surface and to move relative to the discharge port surface in order to clean adherents attached to the discharge port surface. The discharge port includes a plurality of protrusion portions extending toward a discharge port inner side. The contact portion includes a fiber, and the fiber in the contact portion includes a portion having a size greater than a minimum protrusion distance among protrusion distances between the protrusion portions.

Abstract: If the refrigerant amount balance control is executed, since degrees of opening of indoor expansion valves are narrowed in indoor units whose refrigerant superheating degrees are smaller than an average refrigerant superheating degree, amounts of refrigerant flowing into the indoor expansion valves are decreased. On the other hand, in the indoor unit where the refrigerant superheating degree is higher than the average refrigerant superheating degree, since refrigerant pressure on a downstream side of the indoor expansion valve is also decreased due to the degrees of opening of the indoor expansion valves being narrowed, the difference in pressure between the upstream side and the downstream side of the indoor expansion valve increases and an amount of refrigerant flowing into the indoor unit is increased. Accordingly, cooling ability of the indoor unit increases.

A control unit stops conveyance and fixes the relative position between the detection surface and the print medium to the first state, using the fixing unit, in a case in which the reading unit reads the image, and changes the relative position between the detection surface and the print medium from the first state to the second state, using the fixing unit, and resumes conveyance after image reading by the reading unit is complete.

Abstract: In a printing apparatus according to an embodiment of the present invention, it is possible to inspect an image of a printed product where an image is printed accurately without scratching a print medium as the printed product. In the printing apparatus, first, a reading unit reads the image on the print medium conveyed by a conveyance unit, and a fixing unit fixes the print medium to a reading area by the reading unit. Then, control is performed so as to stop conveyance by the conveyance unit and fix the print medium by the fixing unit at the time of image reading, and release fixing of the print medium by the fixing unit and resume conveyance by the conveyance unit if the image reading is complete.

Abstract: When fixing is not necessary in a printing apparatus including a fixing unit, a sheet to be conveyed is allowed to avoid the fixing unit. Specifically, a fixing unit-bypass path is provided on a conveying path corresponding to the fixing unit. Further, when a surface treatment material is not applied to a sheet from a surface treatment material applying head, that is, when fixing processing is not performed by the fixing unit, a sheet is conveyed along a fixing unit-bypass path. Since a sheet is conveyed along an bypass path when fixing processing is not performed as described above, it is possible to prevent a sheet from being affected by heat or the like while the sheet passes through the fixing unit.

Abstract: In a printing system capable of selectively performing duplex printing and simplex printing, a switching unit switches a sheet travel path between a first path and a second path parallel to each other, and reverses the sides of a sheet that passes along the first path. In the duplex printing, a sheet is printed on a first side by a first printing apparatus, reversed by the switching unit, and printed on a second side reverse of the first side by a second printing apparatus. In the simplex printing, only one side of a sheet is printed by the first printing apparatus and/or second printing apparatus. First and second input units introduce sheets into the first and second paths, respectively; and first and second output units receive printed sheets that have traveled along the first and/or second paths.

Abstract: In a printing system capable of selectively performing duplex printing and simplex printing, a first input unit and a second input unit are adjacent to each other. A first output unit and a second output unit are adjacent to each other. In duplex printing, a sheet supplied from the first input unit is printed on a first side thereof in a first printing apparatus and the traveling direction thereof is changed at a changing unit while the sheet is reversed, and then the sheet is printed on a second side thereof in a second printing apparatus and output to the second output unit. In simplex printing, a sheet supplied from the first or second input unit is printed on one side thereof and the traveling direction thereof is changed at the changing unit, and then the sheet is output to the first or second output unit.
