Abstract

PURPOSE: To make a device small-size, light-weight, and snexpensive by providing a supporting material, which is provided with a seal material which can seal the aperture of a bottom plate of a cartridge case, on a substrate fitted with a spindle.
CONSTITUTION: Supporting material 4 is fixed onto substrate 1 fitted with spindle 2, and ring-from seal material 15 which can seal aperture 7 of bottom plate 6a of cartridge case 6 is fitted to the upper face of material 4. Gap A between the inside face of seal material 15 and spindle frange 3 is made as narrow as possible. Clean air is fed into case 6 by blowing mechanism 20 to make the inside pressure higher than the outside pressure, so that dust is prevented from entering into case 6. As a result, the device is made small-size, light-weight, and unexpensive.
