The conveyance path merging section comprises a conveyance roller pair that conveys the sheet fed from the first conveyance path and the second conveyance path through a nip; a variable mechanism that makes an arrangement angle of one roller of the conveyance roller pair to the other roller thereof variable; and a transmission mechanism that transmits a driving force from the upstream side roller provided in one of the first conveyance path and the second conveyance path to the variable mechanism.

Sheet feed device and image forming apparatus

An image forming device includes an image forming unit, a roller unit, a static elimination brush, a moving unit, and a control unit. The static elimination brush eliminates static electricity of the printing medium. The moving unit moves the static elimination brush between a first position that does not intersect a first conveyance path on a downstream side of the roller unit in the conveyance path and a second position that intersects the first conveyance path. The control unit controls the moving unit during the conveyance of the printing medium, positions the static elimination brush at a position different from the second position until a front end of the printing medium passes an intersection position at which the static elimination brush and the first conveyance path intersect if the static elimination brush is positioned at the second position, and moves the static elimination brush to the second position after the front end of the printing medium passes the intersection position until a rear end of the printing medium passes the intersection position.

It is an object of the present invention to provide sheet supplying apparatus. The sheet supplying apparatus has a tray; a guide mechanism; a movement conversion mechanism; a rotary member; a cam and slider mechanism and a compression spring. The movement conversion mechanism converts an up and down motion of the tray to a rotational motion. The rotary member comprises a transmitted portion configured to receive a rotational motion converted from the up and down motion of the tray in cooperation with the movement conversion mechanism and a driven portion configured to receive a rotational driving force to lift the tray. The cam and slider mechanism converts the rotational motion of the rotary member to a linear motion of a linearly movable member. The compression spring elastically presses the linearly movable member of the cam and slider mechanism in the rotational axis direction to lift the tray.

In accordance with one embodiment, an image forming apparatus is equipped with a conveyance device configured to include a rotatable first pulley and a rotatable second pulley arranged side by side, a belt hung on a first pulley and a second pulley and a conveyance roller connected with the belt on the outer periphery of the first pulley and rotating together with the belt, and sandwich and convey a recording medium at a nip part between the conveyance roller and the belt. The axis of the second pulley of the conveyance device is rotated by the rotating mechanism by taking the axis of the first pulley as a fulcrum.

After applying an ultraviolet ray hardening resin compositeon a print patternof dry state and also permeating the resin composite through the print pattern to thereby reproduce the adhesion of the print pattern, the print patternis transferred under water pressure onto the surface of articleto form the decoration layerD on the surface of the article. Then, the preliminary irradiation of ultraviolet ray permeating only near the surface of this decoration layerD is performed to form a fine surface height variation portionby shrinkage of ink in the surface of the ink printing portion of the decoration layerD. Thereafter, the complete irradiation of ultraviolet ray permeating through the total thickness of the decoration layerD is performed to completely harden the total thickness of the decoration layerD while maintaining the surface height variation portion. This enables the matting of the decoration layer in a controlled state without applying a topcoat.
