Abstract: An overhead image-reading apparatus includes an imaging unit integrally formed with a light source, and a light amount adjusting unit that adjusts a light amount so as to keep luminance of a surface of a medium to be read constant based on a correction value of the light amount corresponding to an object-image distance.

Abstract: According to the charge control method of the present invention, as an electric storage means, a group of capacitors is used that include 2n (where n is an integer of 2 or more) electric double layer capacitors, from first to 2n-th electric double layer capacitors, having an equal electrostatic capacity, and that is configured such that adjacent electric double layer capacitors are connected either in series or in parallel by a switch and the 2n-th electric double layer capacitor and the first electric double layer capacitor are connected in parallel by a switch. Among the 2n capacitors Ci constituting the electric storage unit 21, adjacent capacitors are sequentially switched from a series connection to a parallel connection, or the 2n-th capacitor C2n and the first capacitor C1 are switched to a parallel connection state, whereby variations in the inter-terminal voltages of the capacitors are suppressed.
