PURPOSE:To provide a device which is strong to oscillations and dust by mounting a supporting member via an oscillation absorbing mechanism to a body casing of a mechanical device, and mounting the internal mechanism of the mechanical device, to said supporting member. CONSTITUTION:An optical mechanism part and a photosensitive drum are supported by one piece of a support plate 6, and this plate 6 is mounted to body frames 701, 702 via a rubber vibration isolators 801-804, whereby the large oscillations produced in a printing mechanism part 2 are so set as to be transmitted at the same level to a photosensitive drum 201 and an optical mechanism part 3, and are prevented from giving adverse influence upon the image. The isolators 801, 803 in the lower part absorb the osicllations in the vertical direction of the plate 6 and the isolators 802, 804 in the upper part absorb the oscillations mainly in the lateral directions. |
