<p>PURPOSE: To apply ultrasonic wave welding to a transparent indicator for an attention raising lamp for an incoming call signal from a portable telephone set. CONSTITUTION: In the portable communication equipment having a swollen step section 11 formed by a major object other than lamp display for a speaker area to an upper part of a front side of a cabinet 1, the transparent indicator 3 for an attention raising lamp for an incoming call signal or the like is mounted so that the indicator is almost mated to a height of the surface of a contour part while being fitted to a mount hole 13 penetrated between the front side and the rear side of the cabinet on the contour part of the swollen step section 11 toward a cabinet ceiling plate and open at least from the front face of the cabinet 1 in connection to the upper side. Then a mount face is formed to the inner face of the cabinet while enclosing the through mount hole 13 over the entire circumference on the same face by forming a welding section extended outward on the same plane at the circumferential ridge of the end of the indicator in the cabinet. The welding section of the indicator 3 is welded to the mount face by using an ultrasonic wave.</p> |
