PROBLEM TO BE SOLVED: To prevent miss operation of an operation button and a reset button for selecting processing content, and to operate the operation button for selecting the processing content with a light force and the reset button with a strong force. SOLUTION: A front descending slant face 8 mounted on the upper face of a main body case 1 is provided with the operation button 9 and the reset button 10 for selecting the processing content. The operation area of the operation button 9 for selecting the processing content is made larger than that of the reset button 10. An operation force for operating the reset button 10 is made larger than that for operating the operation button 9 for selecting the processing content. The operation button 9 for selecting the processing content is placed on the front lower part of the front descending slant face 8. The reset button 10 is placed on the rear upper part of the front descending slant face 8. The slant of the portion of the rear upper part of the front descending slant face 8 laid out with the reset button 10 is made gentler than that of the front lower part of the front descending slant face 8 laid out with the operation button 9 for selecting the processing content.
