To provide a charge reception device which has a push button and a touch panel, improves its own reliability by using the touch panel as a redundant system in consideration of the breakage of the push button, and reduces a failure rate during execution of work as much as possible.

A push button and a touch panel are arranged together as an input part, in consideration of the breakage of the push button which is frequently used in usual operation work. Even if the push button is broken during an operation, the input part is changed from the push button to the touch panel by a screen-changing button to use a touch panel button having a function equivalent to that of the push button displayed on the touch panel as a redundant system. At that time, the touch panel button corresponding to the push button to be displayed on the touch panel is determined based on data which are registered with a table stored in a storage of a charge reception device.
