Abstract: An image forming apparatus includes a rotatable operation portion including a switchable display screen portion, a frame holding the display screen portion; a light-emitting diode to light up, flashes, or turns off; a light source substrate provided with the light emitting diode; a light guide member which is fixed to an edge on a front side of the main assembly with respect to the display screen portion and which is provided with an emission opening through which the light emitted by the light emitting diode is directed to an outside. The light guide member is fixed such that a plane of the light emission opening of the light guide member is within a range of 45°±15° with respect to the display screen portion. The emission opening of the light guide member faces the light emitting surface of the light emitting diode.

Abstract: An apparatus includes a reading unit configured to read an image of a document set on a reading surface, a pressing plate capable of opening and closing relative to the reading surface, and an operation device provided on an upper surface of the pressing plate and including a plurality of capacitance touch switches each having a backlight. A control unit of the apparatus changes states of the backlights according to operation modes.

Abstract: There is provided a power conversion system, and a photovoltaic inverter includes a communication unit that broadcast-transmits a setting request signal of a predetermined communication address. The photovoltaic inverter includes a display unit that displays the predetermined communication address indicated by the setting request signal, and an address setting unit that generates a setting completion signal indicating that the predetermined communication address has been set as the communication address of the photovoltaic inverter if an input accepting unit accepts an input such that the predetermined communication address is set. An address management unit of the photovoltaic inverter generates a setting request signal indicating a communication address other than the predetermined communication address if the setting completion signal for the predetermined communication address is received.
