PROBLEM TO BE SOLVED: To easily change an optical characteristic in a personal digital assistance device having camera function. SOLUTION: This personal digital assistance device having camera function is provided with an enclosure 10 in which an imaging module 16 comprised of a lens and an imaging device are arranged. A cover member 12 wherein an adaptor optical system 26 different from the lens is provided at a specified position is joined with the enclosure 10 in a first state where the optical axis of the lens is nearly aligned with that of the adaptor optical system 26 and in a second state where, when the adaptor optical system 26 is reversed, the optical axis of the lens is nearly aligned with that of the adaptor optical system 26. The optical characteristic of a synthetic optical system between the lens and adaptor optical system 26 in the first state, optical characteristic of the synthetic optical system in the second state, and a first optical system are made different from each other. |
