Abstract: An electronic device includes a touch panel having a power reception unit that receives power from a power transmission device in a contactless manner and a touch sensor, a driving frequency change unit that changes, in a case where it is detected that the power reception unit is being charged in a contactless manner, a driving frequency of the touch panel from a first frequency to a second frequency, and a threshold change unit that changes, in a case where it is detected that the power reception unit is being charged in a contactless manner, a minimum detection value of the touch panel from a first threshold to a second threshold, which is smaller than the first threshold.

Abstract: A mobile information terminal has: an operating position detecting part 37 that detects an operating position of a user on the basis of an output of an electrostatic capacitance sensor 30 that includes a thin film having a plurality of electrodes and detects an electrostatic capacitance of each of the electrodes; a direction input control part 31 that senses movement of the operating position on the basis of an output of the operating position detecting part, and generates a direction input signal; a key input part 32 that detects a pressing operation of the user on a pressing face of an operation key, and generates a key input signal; a display 22 having a display screen; and a display control part 34 that controls a display position of image information in the display screen on the basis of the direction input signal.

Abstract: An image forming apparatus includes a sheet ejection sensor 4 disposed immediately downstream of a fixing device 3 that detects the passage of a sheet P, time measurement means 61 that measure a time T4 from when a print start signal is transmitted during an margin adjustment to when the sheet is detected by the sheet ejection sensor, time storage means 62 that store a proper setting time T5 that is considered as an appropriate time from when the print start signal is transmitted to when the sheet is detected by the sheet ejection sensor so as to set predetermined end margins, and control means 63 that automatically corrects an signal transmission timing of the print start signal so as to achieve a match between the measured time measured by the time measurement means and the proper setting time stored by the time storage means.
