PROBLEM TO BE SOLVED: To provide an item selection input device on which a customer easily executes the selection input of an item without mistakes on an extension of a conventional menu book having photographs. SOLUTION: Menu sheet parts 20A to 20C are connected to a common electronic circuit part 10 with common connectors 15 and 25, and a customer switches the parts 20A to 20C in attachable and detachable manners as necessary. The part 10 which is relatively expensive is permanently used. On the other hand, because the part 20A which carries many cooking pictures in a large area uses paper as material and forms in internal circuit pattern 23 with silk screen printing, it is inexpensively offered. Also, it inexpensively copes with seasonal menu changes and the addition of a new menu. |
