<p>PROBLEM TO BE SOLVED: To prevent the deterioration of the sound quality of a voice output device due to the input of a cursor key button by suppressing any wrong operation of the cursor key button. SOLUTION: The front face of the case body of a computer main body 1 is provided with a recessed part 8, and a cursor key button 5 and an input key button 6 are arranged on the recessed part 8 so that any possibility that those key buttons are depressed by mistake can be reduced. Also, a speaker and a voice output port 4 are not integrally formed with the cursor key button 5, and fixed to the case body of the computer main body 1. Thus, even when the cursor key button 5 is depressed, and the direction of the cursor key button 5 is changed, the voice output direction of the speaker is fixed.</p> |
