摘要： An image forming apparatus includes a first detector detecting an operation sound based on a sound wave received by a receiver; a second detector detecting basis weight of recording material based on an ultrasonic wave transmitted from a transmitter and received by the receiver; a switching unit that switches destination of a reception signal from the receiver between a first path to the first detector and a second path to the second detector; and a controller that controls the switching unit such that the reception signal is output to the first path at a first timing and to the second path at a second timing. When a predetermined condition is satisfied, the controller controls the switching unit such that the reception signal is output to the second path at the first timing or to the first path at the second timing.

摘要： A photoelectric conversion apparatus is provided. The apparatus comprises a substrate including two light receiving regions in which light receiving devices are arranged; electrode pads arranged on the substrate; and a readout circuit arranged on the substrate and configured to read out signals from the light receiving regions. The electrode pads include an output pad for outputting a signal, and a power supply pad for supplying power to the light receiving regions or the readout circuit. Each of the light receiving regions has a shape in which a first direction is taken as a longitudinal direction, the light receiving regions are arranged along a second direction with an interval therebetween, the second direction intersecting the first direction, and one or more pads of the electrode pads is sandwiched by the light receiving regions in the second direction.
