摘要： An image forming apparatus having a plurality of functional units includes a power failure detection circuit configured to detect a power failure of an external power supply for the image forming apparatus, a rechargeable battery unit, and a control unit. The control unit switches the power supply source of the image forming apparatus from the external power supply to the rechargeable battery unit, and selects one or more of the functional units to power through the rechargeable battery unit based on a remaining capacity of the rechargeable battery unit, when the power failure of the external power supply is detected.

摘要： A printing apparatus that has a plurality of functions including a printing function and is capable of executing printing with resolution of 300 dpi or more includes a plurality of operating units including a printing unit and a power supply unit. The power supply unit includes a substrate, an input terminal that receives an alternating voltage, a smoothing capacitor that smooths the alternating voltage, a thermistor that detects a temperature, and a comparator that compares a signal output from the thermistor with a standard signal and outputs a notification signal. The input terminal, the smoothing capacitor, the thermistor, and the comparator are mounted on the substrate. The supply of power from the power supply unit is stopped based on the state of the notification signal. A gap between the input terminal and the thermistor is longer than a gap between the input terminal and the smoothing capacitor.

摘要： In an inkjet printer, from one side of a main scanning direction, first through fourth ultraviolet irradiation devices arrayed in the main scanning direction at least partially overlap first and second recording heads. A distance in the main scanning direction between a middle position in the main scanning direction of the first recording head and a middle position in the main scanning direction of the first ultraviolet irradiation device is equal to a distance in the main scanning direction between the middle position of the first recording head and a middle position in the main scanning direction of the second ultraviolet irradiation device. A distance in the main scanning direction between a middle position in the main scanning direction of the second recording head and a middle position in the main scanning direction of the third ultraviolet irradiation device is equal to a distance in the main scanning direction between the middle position of the second recording head and a middle position in the main scanning direction of the fourth ultraviolet irradiation device.

摘要： A print device includes a first print portion, a first discharge portion, a second print portion, a second discharge portion, and a user interface portion. The first discharge portion is configured to discharge a first medium printed by the first print portion. The second discharge portion is configured to discharge a second medium printed by the second print portion. The user interface portion is disposed on a front side portion of the print device. A main scanning direction of the first print portion and a main scanning direction of the second print portion are substantially parallel to an up-down direction. A length in the up-down direction of the second print portion is shorter than a length in the up-down direction of the first print portion. The second print portion is disposed to the front of the first print portion.

摘要： 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.
