Abstract
A portable electronic device includes a main unit which has operation switches, and an operation panel which has operation buttons that press the operation switches and which is rotatably mounted on the main unit. The operation panel can be freely attached to and detached from the main unit and can be replaced with another operation panel if needed. The ability to replace the operation panel makes it possible to have multiple types of operation panels available and to select operation panels whose operation buttons are different and mount them on the main unit.
