A mobile device configured to be coupled to a counterpart device includes a driving section configured to be driven by electric power, a coupling section configured to be coupled to the counterpart device, and an accommodation section configured to accommodate an all-solid-state battery. When the counterpart device is coupled to the coupling section, the driving section is driven by electric power supplied from the counterpart device, and when the counterpart device is not coupled to the coupling section, the driving section is driven by electric power supplied from the all-solid-state battery.

Power required for a printing operation can be supplied while supplying power to a connected external device. A printer 1 connects to a smart device 2, and has: a power circuit 14; a USB interface 15 capable of supplying power to the smart device while communicating by wire with the smart device 2; a print unit 16 that prints; and a controller 11 that controls the print unit 16 to print in a power conservation mode when information instructing printing by the print unit 16 is received by the interface 15 from the smart device 2 while supplying power from the power circuit 14 to the smart device 2.

A recording apparatus includes a carriage which is capable of moving along a first direction, a first sliding section that is provided in the carriage, on one side in a second direction, which intersects the first direction, a second sliding section that is provided, in an arm section, which extends from the other side, protruding in the second direction, a tube that supplies the liquid, which is delivered from a liquid accommodation section, to the carriage, extends in a direction that intersects the second direction by extending out from the carriage, and extends in an opposite direction by turning back in a vertical direction, in which the tube extends in the direction that intersects the second direction by passing at least one of above and below the arm section.

Provided are a recording apparatus and a motion unit drive method that determines a stop rotation torque of a CR motor indicating stop of a carriage by a stopper and, within a predetermined period after the determination of the stop rotational torque, supplies to the CR motor the drive signal that causes a rotational torque of the drive motor to be a low rotational torque having a smaller torque value than the stop rotational torque.

To operate a printing apparatus with small power, the printing apparatus for printing an image on a print medium using power of an electric storage charged by power input from an external power supply performs the following control. An operation sequence for printing on the print medium is divided into a plurality of sequences. Each of the divided sequences is executed by discharging power charged in the electric storage. Next, power is charged in the electric storage during a standby time of the operation sequence after execution of one divided sequence ends. An electric storage amount charged in the electric storage is compared with a predetermined threshold. Then, control is performed to execute the next sequence in a case where the electric storage amount becomes larger than the predetermined threshold.
