PROBLEM TO BE SOLVED: To enable simply attaching a desired optional apparatus to a main body case of an electronic apparatus without applying modification to the main body case. SOLUTION: A main body side attaching part 4 for attaching an optional apparatus is formed on the case body 2 of the electronic apparatus 1 for a POS, and an attaching part cover 5 is attached on the attaching part 4. On various kind of optional apparatuses to be attached on the case body 2, e.g. on an optional apparatus 10, an optional apparatus side attaching part 13 which has interchangeability with the attaching part cover 5 is formed. As a result, the optional apparatus can be attached by simple work wherein the attaching part cover 5 is detached and the attaching part 13 of the optional apparatus 10 is attached on the main body side attaching part 4 instead of the cover 5, so that it is unnecessary to apply modification to the case body 2.
