<p>In the left and right sides of a bezel (40), guide grooves (42) are made, extending straight in the front-back direction. A cap (50) has hinge pins (52), which are fitted in the guide grooves and which can slide along the guide grooves. Control pins (44) protrude inward from the left and right sides of the bezel, and may abut on the back of the cap covering the opening of the bezel. If the cap is pushed, sliding the hinge pins along the guide grooves, the back of the cap slides on the control pins, and the cap swings around the hinge pins. As a result, the cap jumps up and is stored into the bezel.</p> |
