PROBLEM TO BE SOLVED: To provide a data processor having no anxiety of false detection even if the number of kinds of externally-connected apparatuses is increased. SOLUTION: The data processor 10 includes an A-function part 12a, a B-function part 12b or the like, and includes an external interface connector 11. ID data are set in an A-external apparatus 21a, a B-external apparatus 21b or the like selectively connected to the external interface connector 11, and the ID data are previously registered in an ID data storage part 16 in the data processor 10. When the A-external apparatus 21a is connected to the external interface connector 11, for example, the data processor 10 detects the ID data by an ID data detection part 14, collates them with registration data of the ID data storage part 16 in an ID data collation part 15, changes over selectors 13a, 13b based on a collation result thereof, and connects the A-external apparatus and the A-function part 12a corresponding to the A-external apparatus 21a.
