PROBLEM TO BE SOLVED: To provide on-vehicle electronic equipment capable of securing on-vehicle performance such as reduction of weight, vibration resistance, electromagnetic shield performance and dust-proof performance.SOLUTION: By using a resin housing 40, weight can be reduced and, by forming the housing in a cylindrical shape, strength as the housing can be secured and a media drive circuit substrate assembly 2 can be protected from dust, water and an attachment handling to a vehicle. By using a metal holder 30 having an area of the bottom surface or more of a media drive 10, substrate ground is reinforced, an electromagnetic noise occurring from a circuit substrate 20 can be reduced and an electromagnetic noise occurring from an FPC 12 and the media drive 10 can be shielded. Further, metal brackets 50, 60 retain the media drive 10 as a heavy weight matter, therefore, a load burden to the resin housing 40 is reduced and vibration resistance can be secured. Further, the sheet metal housing of the media drive 10 is connected to vehicle ground via the metal brackets 50, 60 and, thereby, the electromagnetic shield performance is improved. |
