<p>PURPOSE:To prevent the reduction of the air flow rate of an air intake part by securing a constitution where the air intake part is slid with handset when the handset is loaded/unloaded and therefore the dust, etc., attached to the air intake part are removed away. CONSTITUTION:An air intake part 30 where the outside air is supplied via a cooling fan device 16 incorporated in an equipment main body 1 is set opposite to a handset 2 attached to the main body 1. Therefore the dust-proof net of the part 30 is slid with a call reception part 3b and cleaned when the handset 2 is loaded into and unloaded out of an upper half 9. Thus the dust, etc., are never stuck to the dust-proof net and this net is free from the clogging. Consequently, the flow rate of air passing through the dust-proof net is never reduced and the device 16 can always secure the satisfactory cooling effect.</p> |
