Abstract: With a mounting operation of a supply container, a supported portion 11b of a developer receiving portion 11 is supported by a receipt supporting portion 30c of a lifting portion 30. With further mounting operation, a shutter sliding portion 30b of the lifting portion 30 slides on a shutter inclined portion 4f of a shutter 4. The developer receiving portion 11 is displaced so as to bring a receiving opening into communication with a discharge opening by operating, using the shutter 4, the lifting portion 30 supporting the supported portion 11b of the developer receiving portion 11. By this, a load required for movement of the developer receiving portion 11 is reduced to achieve smooth mounting of the supply container.

Abstract: A coil holding apparatus for laying a concentrated wound cassette coil in which a wire is laminated in multi layers, including a plurality of supporting parts configured to support the concentrated wound cassette coil, in which the plurality of the supporting parts include a first supporting part having a first height in the vertical direction and a second supporting part having a second height different from the first height in the vertical direction. The concentrated wound cassette coil includes an upper surface and a lower surface, each of the plurality of the supporting parts includes a supporting surface that is brought into contact with the lower surface and that supports the concentrated wound cassette coil.

Abstract: To provide a processing apparatus for a flat wire adapted to suppress adhesion of a shaft and improve durability. A processing apparatus includes: a holder including a rotation axis for rotating in a bending direction of a flat wire; and a clamp including the rotation axis for rotating in the bending direction and configured to restrain the flat wire by clamping it with the holder, in which the clamp includes: a flange that restrains the flat wire between it and the holder; a shaft connected to the flange and disposed so as to pass through a penetrating hole formed in the holder; and a coating film formed on a surface of the shaft, and in which a hardness of the shaft and a hardness of the coating film are greater than a hardness of the holder.
