Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem that it is difficult to secure sufficient shock resistance against an external force such as the bending moment.SOLUTION: A window member 50 formed of a transparent synthetic resin is stuck to a rear cover 40 (housing) while blocking an aperture of the rear cover. The rear cover 40 has an annular groove 40m1 on its back side surface, and an annular groove 40m2 on its front side surface, and the two annular grooves are formed all over the circumference of the aperture along an outer periphery of the aperture of the rear cover 40. When the external force is applied to the window member 50, a beam 40n put between the two annular grooves 40m1 and 40m2 which are opened on opposite surfaces (front surface and back surface) functions as a damper so as to make the bend of the rear cover and absorb a shock caused by the external force, thereby protecting the window member.
