摘要： A recording and/or reproducing apparatus and a magnetic disk cassette having a flexible magnetic disk and a cover for containing the magnetic disk. The cover has a driving hole for driving the flexible magnetic disk from outside of the cover, a recording opening for exposing a recording surface of the flexible magnetic disk, and a cut-out portion provided on one side of the cover for detecting correct installation of the flexible magnetic disk cassette into a recording and/or reproducing apparatus. A shutter is slidably provided on the cover for selectively exposing the recording surface through the recording opening and the cut-out portion when the flexible magnetic disk is ready for use. The recording and/or reproducing apparatus for the flexible magnetic disk cassette includes a driving member engaged with the flexible magnetic disk through the driving hole of the cover for rotating the flexible magnetic disk. A transducing head is contacted with the recording surface of the flexible magnetic disk through the recording opening when the shutter is in an operative position. A projection is provided in the apparatus in facing relation to the cut-out portion of the cover when the flexible magnetic disk cassette is installed correctly.

摘要： The invention provides a resin-sealing apparatus that is operated with a low pressure and with a low clamping force without void generation and that is favorable for shortening the molding time and reduction of sealing resin consumption. In the resin-sealing apparatus of the present invention, a resin injection inlet of a pot has an opening at the center of the cavity surface of a cavity of a bottom mold that is a component of a mold unit, and a plunger for injecting molten resin in the pot from the opposite side to the resin injection inlet side is provided slidably and airtightly with the inside wall of the pot.
