The objective of this invention is to prevent dust from entering a case. The solution of this invention is that: a tape-shaped sealing stripe is provided and having a length capable of crossing on a top of a platform for sealing an opening, an sealing stripe guide part is in contact with the tape-shaped sealing stripe while the tape-shaped sealing stripe crosses on the top of the platform so as to bend the tape-shaped sealing stripe, thus an elastic thrust is generated for fixing the portion of the tape-shaped sealing stripe, which does not cross the top of the platform, to an adhesion component, and a slide sheet seals gaps formed between a platform cover and the top of a lateral cover and the tape-shaped sealing stripe while the tape-shaped sealing stripe crosses the top of the platform. |
