Abstract: A charge control device uses external electricity to charge a plurality of battery devices. A constant current source uses the external electricity to generate and adjust an output current amount to a constant target value. A selector selects one battery device from the plurality of battery devices and supplies output current from the constant current source to the one battery device. A measurer measures an amount of actual current flowing from the constant current source to the one battery device. An instructor monitors a measured value provided by the measurer and instructs the selector, when the measured value meets a condition for a reduction of charging current amount to be regarded as having occurred, to change a destination to which the output current of the constant current source is supplied from the one battery device to a different battery device.

Abstract: A sheet feeder picking up and transporting sheets includes a transport unit transporting sheets along a sheet transport path one by one, a gap occurrence detection unit detecting, within a predetermined section of the sheet transport path, occurrence of a gap between sheets, and a controller controlling a timing of the transport of sheets according to a result of the detection. The gap occurrence detection unit includes a first detection unit and a second detection unit. The first detection unit is configured to detect light that is emitted toward the predetermined section, reaches a converging surface thereof across the predetermined section, and converged on a receiving element thereof. The second detection unit is configured to detect light reflected by a sheet passing through the predetermined section. The occurrence of the gap is detected based on outputs from the first detection unit and the second detection unit.
