Abstract: An apparatus having a flexible mounting mechanism according to the present invention includes a storage section, a casing accommodating and holding the storage section, a protective housing accommodating and protecting the casing, a supporting member provided between the casing and the protective housing for supporting the casing, and a maintaining member supporting the protective housing. The supporting member and the maintaining member have different vibration damping characteristics.

Abstract: A data recording device, using a disc, wherein it is easy to handle respective audio signals independently and which receives digital data got by multiplexing plural audio signals is provided.

Abstract: An data recording apparatus in accordance with the present invention is configured so as to determine whether a received data block is of the same data to a previously received data block or not on the basis of the data block particular information in the data block transmitted from the outside and stored in a buffer thereby determining the recording-or-not into a disk drive, or so as to determine whether it is to be recorded into the disk drive or not on the basis of the information transmitted from the outside.

Abstract: A storage apparatus of the present invention has an HDA of a storage portion, a box frame for containing the HDA and fixed to the HDA by bolts, and a protection box for incorporating at least the HDA and the box frame. A plurality of supporting members are arranged between the box frame and an inner surface of the protection box, so that the supporting members elastically support the HDA and the box frame in the protection box.

Abstract: A charging device for charging a movable object to be charged. A charging member contacts the object to be charged. A power source applies a voltage to the charging member, wherein the power spectrum PS satisfies the following relation when the space frequency of the profile of the surface of the charging member is analyzed.In the section of 10.ltoreq.f.ltoreq.100 (cycles/mm):PS.ltoreq.-2.5.times.log(f/2)(.mu.m.sup.2)In this way, the charging device prevents charge unevenness due to undulations on the surface of the charging member and charges uniformly while generating very little ozone.

Abstract: A charging device for charging a moving photoconductor. The charging device includes a charging member, an electric power supply for applying a voltage to the charging member, and a light exposing device, such as a LED for exposing surfaces of the charging member and the photoconductor in a closing region where the surfaces of the charging member and the photoconductor move closer to each other. The charging member is a blade having a transparent layer for guiding a light beam from the LED to the closing region and a shading layer for shading the light beam to a contacting region and a separating region. The contacting region is where the surfaces of the charging member and the photoconductor contact, and the separating region is where the surfaces of the charging member and the photoconductor gradually separate from each other.
