CONSTITUTION:A keyboard housing section 11 connected with an electric parts housing space 4 through an opening port section 12 is formed on a main body cover 1. The keyboard housing section 11 is formed by denting the upper surface of a cover 3 to mount a keyboard section 6 on a top cover 3. At the bottom of the keyboard housing section 11, the opening port section 12 is formed, and the section 11 is communicated with the space 4 through the section 12. The keyboard section 6 is mounted on the keyboard housing section 11 freely detachably by covering the opening port section 12. In this case, when the maintenance is performed by removing a flat keyboard 6F and normal keyboard 6N from the keyboard housing section 11, it can be smoothly performed without the restriction of the top cover 3. |
