摘要:
A sheet conveying device, which is included in an image forming apparatus and an optional device attachable to the image forming apparatus, includes a sheet container, a sheet feeder, a separator, a guide, and a projection. The sheet container loads multiple sheets. The sheet feeder feeds a sheet out of the multiple sheets in the sheet container. The separator separates the sheet from another sheet fed together with the sheet. The guide having a guide surface to guide the sheet passing the separator such that the sheet is fed in a predetermined sheet conveying direction. An upstream end in the sheet conveying direction of the guide surface of the guide is located lower than a downstream end in the sheet conveying direction of the separator. The projection is disposed facing the separator at the upstream end in the sheet conveying direction of the guide surface.

An amorphous core transformer is provided which is capable of effectively suppressing influences, fluctuation, displacement or the like of a coil caused by an electromagnetic mechanical force or the like. In an amorphous core transformer 100 including an amorphous core 101, a plurality of coils 102 in which the amorphous core 101 is inserted and a fixing metal frame 110 that assembles the coils 102 and the amorphous core 101, the inter-coil member 106 is interposed between the neighboring coils 102 and the inter-coil member 106 is positioned and held by a positioning member 107. Thus, it is possible to prevent the coils 102 from being deformed or displaced beyond the inter-coil member 106 and maintain the shape of the coils 102.

Disclosed is a wound iron core (3) for a static apparatus in which magnetic paths in the inside of the wound iron core are subdivided to improve iron core characteristics. The iron core (3) is configured by using two or more kinds of magnetic materials (11 to 14) with different magnetic permeabilities to form laminated blocks with single plates or a plurality of laminated plates and by alternately arranging the laminated blocks with different magnetic permeabilities from the inner circumference. An iron core material (14) with large magnetic permeability out of iron core materials with different magnetic permeabilities is arranged on the inner circumference side. Further, when the iron core materials with different magnetic permeabilities are alternately arranged, the iron core materials (11) with the same magnetic permeability are configured to gradually change in thickness to ease an excessive magnetic flux density distribution in the iron core. A ring-shaped iron core is configured such that a plurality of block-like laminated members, which are each formed by laminating a plurality of strip-like amorphous material thin plates, are laminated and formed into a ring shape and a sheet-like non-magnetic insulation material is arranged between the n-th (n: an integer of two or more) layer of the ring-shaped block-like laminated members from the most inner circumference side and the (n+1)-th layer of the ring-shaped block-like laminated members from the most inner circumference side.
