A print system includes a head, a conveyance motor, a first connector, and a second connector, a power supply circuit. When a first power source is connected to the first connector and a second power source is connected to the second connector, the power supply circuit supplies at least some of a first power to the head and supplies at least some of a second power to the conveyance motor. The first power is a power of the first power source. The second power is a power of the second power source.

A power receiving device includes a storage and a computer. The computer stores a first operating condition indicating a past operating condition of the power receiving device in the storage. The computer detects a power supplying capacity within which a power supplying device can supply power and identifies a specific value in relation to the first operating condition from the storage. The computer sets an incoming power based on both the detected power supplying capacity and the identified specific value, thereby allowing the power supplying device to send the set incoming power.

A printer includes a printing unit powered from a battery which is charged by a charge IC, and a processor. The processor sets a mode of the printer to a print mode, and sets the mode to a low-power mode in which total power consumption of the printer is lower than that in the print mode, in a state that the printing unit stops printing. In a case where the processor sets the mode to the low-power mode, the processor sets the mode to a first low-power mode, in which the charge IC is driven at a first SW frequency, when the charge IC works to charge the battery, and sets the mode to a second low-power mode, in which the charge IC is driven at a second SW frequency lower than the first SW frequency, when the charge IC stops the charge of the battery.

A printing apparatus connectable to an external power supply having outputtable voltage information, including: a printing head performing printing by electric power supplied from the external power supply; a resistor having an electric resistivity based on the printing head; a detector detecting a substantial voltage; and a controller configured to: obtain the voltage information from the external power supply; decide a tentative voltage; request the external power supply to output the tentative voltage; energize the resistor with the tentative voltage; decide the substantial voltage if a voltage corresponding to each of the obtained voltage information is supplied based on a result of the detector during the energizing of the resistor; decide an electric power supply voltage based on the substantial voltage; and request the external power supply to output the electric power supply voltage.

A display device, configured to display an image photographed by a camera mounted on a remotely controlled mobile object, includes a display part which is mountable on a head of a user and capable of displaying an image, a receiving part configured to receive a photographed image and position information of the mobile object transmitted from the mobile object, a position detection part configured to detect a position of the display part, a direction detection part configured to detect a direction of the display part, and a controller configured to control image displaying on the display part, determine whether the mobile object exists in the direction of the display part and within a particular range with respect to a position of the display part, and switch images to be displayed on the display part depending on whether the mobile object exists within the particular range or not.

Display device and display control method

A head-mounted display includes a mounting fixture mounted on a user's head, an image display device including an image light unit that generates image light, a half mirror, and a casing, a connection fixture that mounts the image display device with respect to the mounting fixture, a first ball joint that connects the mounting fixture and the connection fixture, and a second ball joint that connects the image display device and the connection fixture. The connection fixture holds the image display device in front of a user's eyes. The second ball joint extends in right and left directions, and rotatably supports the image display device with respect to the connection fixture in a state in which a rotational axis, disposed on a rear side of the image display device, is set as a supporting point. The second ball joint changes a direction of image light that is emitted.

A tamper prevention system includes a mounting unit, a portable terminal device, a first data input unit, an authentication unit, a detecting unit, and a setting unit. The portable terminal device enables a user to input operation data, performs an operation in accordance with the operation data when a first mode is set, and fails to perform the operation when a second mode is set. The first data input unit enables the user to input first data. The authentication unit authenticates the user when the first data matches authentication data. The setting unit sets the portable terminal device to the first mode when the authenticating unit has authenticated the user, and sets the portable terminal device to the second mode when the authenticating unit has failed to authenticate the user and the detecting unit has detected that the portable terminal device is removed from the mounting unit.
