Abstract: First terminals are usable as input terminals or output terminals and second terminals are usable as input terminals. A switching unit switches the first terminals between input and output, based on an instruction indicating the number of first terminals to be used as output terminals. If at least one first terminal is used as an output terminal, a first signal is output to the first terminals used as output terminals. A storage unit (stores second and third signal values, the second signal value being a value of a second signal input from the input terminal, the third signal value being a value obtained by arraying a plurality of the second signal values based on the value of the first signal. A setting unit reads the second signal value or the third signal value based on the instruction signal, and acquires information on the value of the second signal input.

Abstract: A display device includes a display panel, a detachable light source, a lighting device, and a display controller. The lighting device includes an attaching and detaching slot in one side surface. The display controller is configured to control driving of the display panel so that an orientation of the image with the display device set in a first position in which the attaching and detaching slot faces toward a first side of a first direction corresponds with an orientation of the image with the display device set in a second position in which the attaching and detaching slot faces toward a second side of the first direction and the display device is inverted from the first position. The first direction is in which attachment and the detachment of the detachable light source is performed. The orientations are with respect to a second direction perpendicular to the first direction.

Abstract: A power supply unit for an electronic device comprises a three-terminal regulator in a high voltage connection line between a high voltage terminal of a DC power supply circuit and a microcomputer for reducing voltage from the high voltage terminal to a lower first voltage. A low voltage connection line between a low voltage terminal of the power supply circuit and the microcomputer is connected to the high voltage connection line at a connection point on output side of the regulator. In standby mode, voltage from the high voltage terminal, set higher than the first voltage, is reduced by the regulator to the first voltage and supplied to the microcomputer. In power-on mode, voltage from the low voltage terminal, set higher than the first voltage, is applied to the connection point so as to inactivate the regulator and supply the voltage from the low voltage terminal to the microcomputer.
