<p>PURPOSE:To provide an information processor formed into an air hole lattice which prevents clogging between lattice of an air hole due to dust included in air discharged from a cooling fan even at the time of using the processor for a long period. CONSTITUTION:On the constitution of the whole of an information processor 1, a storage device 4, an auxiliary storage device 5, and a power source 7 on which a control substrate 6 is arranged and which devices rear parts 6 and 5, etc., are provided. Since heat is generated from the power source 7, the substrate 6, etc., during the operation of the processor, a cooling fan 17 is provided on the rear part of the power source 7 as a processor inside cooling method. The fan 17 is directly fixed to a back plate 18 in the rear part by screws 21. Air is discharged from the fan 17 through an air hole 23, and the air hole 23 is provided on a position determined in consideration of the air discharge efficiency and the form of a back cover 22 made of a synthetic resin. An air discharging guide 20 is provided on all peripheries of the air hole 23 and forms a slope 34 toward a hole 33 together with a transversal lattice 31 of the air hole and a longitudinal lattice 32 reinforcing this lattice 31 and is abutted on the back plate 18 with a prescribed force to be held.</p> |
