<p><P>PROBLEM TO BE SOLVED: To provide a foldable electronic device which can increase an assembling efficiency by reducing the number of components necessary for an opening/closing button. <P>SOLUTION: An opening/closing button 4 comprises a button main body 10 arranged to be moved within a lower case 8, a hook 12 releasably engaged with an engagement extrusion of a lid case, a button member 14 inserted in an opening 13 of the lower case 8 to be moved thereinto or therefrom, resilient arms 15 provided at both sides of the button main body 10 for energizing the main body 10, and pinch-holders 18 provided at tip ends of the resilient arms 15 to be releasably engaged with mounting ribs 17 of the lower case 8. These components are integrally assembled into the button 4. Thus, not only the number of components necessary for the opening/closing button 4 can be remarkably reduced, but the pinch-holders 18 provided at the tip ends of the resilent arms also enables the button 4 to be reliably held in the lower case 8. Consequently, even when the lower case 8 is tilted or located upside down during assembling works, positional deviation or coming off of the opening/closing button 4 can be prevented, thereby increasing an assembling efficiency. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
