PROBLEM TO BE SOLVED: To easily and efficiently carry out a recycle process by displaying recycle information related to parts fixed by a double-coated adhesive tape. SOLUTION: In a paper feed unit, a thin film 21 is fixed by a double-coated adhesive tape 22 to a surface of a plate material 20 constituting a paper feed cassette 10. In the paper feed unit, a mark (R) 23 showing that the thin film 21 can be peeled in a good state is impressed on the surface of the plate material 20 in the vicinity of the thin film 21. A worker can judge, by seeing the mark 23, that the thin film 21 is allowed to be peeled.
