Furthermore a keyboard 4 is added to the front part of the tool 1 together with a stage part 5 formed between a higher place of the front edge of the part 3 and the rear end of the keyboard 4. Then a hook shape part 6 etends upward from the side part of the part 3 and has its upper end part bent inside like a hook. Thus the wrist of an operator can be fitted close to the part 3.
