Abstract: A control device includes a processor. The processor controls an electric power supply to an operating part, and charging and discharging of a secondary battery; estimates electric power being supplied to the operating part and the secondary battery; acquires a charge state for a case of charging the secondary battery; and when a determination is made that the electric power estimated by the processor and being supplied to the operating part and the secondary battery is less than electric power required for a predetermined action to be executed by the operating part and, also, the charge state of the secondary battery is a predetermined charge state, controls so as to limit the predetermined action.

Abstract: An operation state detecting apparatus includes the following. An electronic device includes an operation surface and can detect whether there is contact in a plurality of positions. A sheet material can be attached to and detached from the operation surface. The sheet material includes a projecting portion which deforms to change a contact state on the operation surface according to strength of external force. A processor of the electronic device detects whether there is contact in a plurality of positions in an individual detecting region on the operation surface on which a contact state changes by the projecting portion deforming in a state with the sheet material attached to the operation surface. The processor performs a specific process according to strength or speed of an operation applied to the projecting portion judged based on a detected result of whether contact is detected in the plurality of positions.
