PURPOSE:To cope easily with assembling, maintenance and design change by forming a decoration plate of a dial operating section as a different component from a housing of a handset and mounting circuit elements of the dial operating section, a control section and a display section onto a combined flexible printed board. CONSTITUTION:The printed board 16 has a construction combining the dial switch section 16A, the control section 16B and the display section 16C. Stepped sections 10a, 10b are formed at the inside of a housing 10, a photoconductive plate 13 is fitted to the lower stepped section 10a by bonding at first and then, the decoration plate 11 is fitted to the upper stepped section 10b by bonding similarly. Further, a seal plate 14 where a dial button 15 is inserted to a projection 14a is inserted from the lower side of the housing 10, and then the printed board 16 is assembled. Notches 16a, 16b of the printed board 16 are engaged with claws 11e, 11f of the decoration plate 11 and then, a screw hole 21 is screwed to a screw seat 15b of the photoconductive plate 13 through a screw 16c, and moreover, a screw 22 is screwed to a screw seat 10b of the housing 10 through a screw hole 16d to assemble the handset. |
