Abstract
The main body of the image-forming machine is provided with an image-forming unit and a conveying unit disposed opposite to the image-forming unit. The conveying unit supports a mounting and detaching unit so that it is selectively movable to a set position or a non-set position. A locking means is provided between the mounting and detaching unit and the main body of the image-forming machine. When the mounting and detaching unit is held at the non-set position, the lock means is cancelled, and the conveying unit can be drawn from the main body of the image-forming machine. As a result, a large space is created beneath the image-forming unit, and jamming can be easily disposed of.
Claims15
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the mounting and detaching unit is provided with a paper conveying means including a driving shaft to be driven by a driving means, and the mounting and detaching unit is supported by the conveying unit so that it can be moved selectively using the driving shaft as a fulcrum.
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the conveying unit is provided with a mounting and detaching means for moving the mounting and detaching unit selectively, and wherein said mounting and detaching means is supported on the conveying unit and includes a rotating shaft having an operating lever fixed to its one end, and a mounting and detaching lever fixed to the rotating shaft, the end portion of the mounting and detaching lever having provided therein a roller, said roller being in contact and engaged with the under surface of the mounting and detaching unit.
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the locking means includes an engaging piece provided in the mounting and detaching unit and an engaging hole provided in the main body of the image-forming machine, said engaging piece, when the mounting and detaching unit is at the set position, engages the engaging hole to hamper the movement of the conveying unit in the drawing direction, and when the mounting and detaching unit is at the non-set position, the engagement of the engaging piece with the engaging hole is cancelled to permit the movement of the conveying unit in the drawing direction.
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the image-forming unit is supported so that it can be alone drawn from the main body of the image-forming machine, and between the mounting and detaching unit and the image-forming unit, another lock means is provided so that in interlocking relation to the selective movement of the mounting and detaching unit, it hampers and permits the movement of the image-forming unit in the drawing direction.
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the image-forming machine supports a cassette for holding papers so that the papers may be drawn, a holding means being provided between the cassette and the conveying unit which can hold, and does not hold, the cassette at the set position, and when the lock means provided between the mounting and detaching unit and the main body of the image-forming machine is cancelled, the cassette is drawn integrally with the conveying unit from the main body of the image-forming machine.
A conveying unit in an image-forming machine comprising
- an image-forming unit supported on the main body of the image-forming machine, and
- a conveying unit disposed opposite to the image-forming unit, said conveying unit being supported on the main body of the image-forming machine so that it can be drawn from the main body of the image-forming machine, said conveying unit supporting a mounting and detaching unit so that it is supported selectively movably at a set position or a non-set position with respect to the image-forming unit, a locking means being provided between the mounting and detaching unit and the main body of the image-forming machine for hampering or permitting the movement of the conveying unit in the drawing direction in interlocking relation to the selective movement of the mounting and detaching unit,
- wherein the image-forming unit has provided therein a residual toner discharge opening for discharging a residual toner recovered from the image-bearing member by the cleaning device, and said conveying unit has a residual toner recovery container for recovering the residual toner discharged from the residual toner discharge opening of the image-forming unit, said residual toner recovery container being supported by a supporting means and being constructed such that in interlocking relation to the selective movement of the mounting and detaching unit, the residual toner recovery container is positioned between a residual toner recovery position connected to the residual toner discharge opening and a retired position separated from the residual toner discharge opening.
