摘要:
In a switching node, high-speed and advanced service protocol processing function is achieved by utilizing an external control server without affecting performance of conventional service protocol processing. Specifically, a forwarding engine has PCI express and an LAN interface. Depending on a type of an input packet, destination of the packet is switched to the PCI express side for conventional network service and to the LAN interface side for extended network service that cooperates with the external control server. A CPU having the PCI express and the LAN interface is provided ahead of the LAN interface. The CPU performs communication of service inquiry with the external control server at high speed via the LAN interface. After response from the control server is obtained, setting of the forwarding engine is performed through the PCI express.

A cleaning device for cleaning a printhead of an ink-jet printer. The cleaning device includes, a cleaning unit provided with a cleaning blade, and a traveling unit that carries the cleaning unit. The traveling unit reciprocates between first and second positions to perform a cleaning cycle of the printhead. The cleaning blade is held by the cleaning unit perpendicular to an ink ejecting surface of the printhead to clean the ink ejecting surface when the traveling unit moves in one direction. Further, The cleaning blade is inclined against the ink ejecting surface to avoid being rubbed against the ink ejecting surface when the traveling unit moves in an opposite direction.

An ink-jet printer includes a belt conveyor mechanism, an ink-jet head having at its lower face a nozzle face where many nozzles are formed, and a maintenance unit that maintains the ink-jet head. Within the maintenance unit arranged are a blade, a wiping roller, an ink receiving member, and a purge cap, in this order from the near side to the head. The maintenance unit is first moved to a purge position at which the purge cap confronts the nozzle face of the ink-jet head, where a purge operation is performed. After the purge operation, attendant upon movement of the maintenance unit to get apart from the head, the ink receiving member, the wiping roller, and the blade successively confront the nozzle face in this order. With the movement of the maintenance unit, receiving ink with the ink receiving member and wiping ink up with the wiping roller and the blade are performed in order.

An inkjet recording apparatus includes a recording head, a recovery unit, a reception member, and an arrangement mechanism. The recording head ejects ink therefrom to perform recording on a recording medium. The recovery unit causes the recording head to perform a purge process. The reception member receives the ink ejected in the purge process and has flexibility. The arrangement mechanism stores the reception member, which is in a wound state, outside a recoding area where the recording head performs the recording on the recording medium. The arrangement mechanism pulls out the reception member when the recovery unit causes the recording head to perform the purge process.

Disclosed is a method of recording a picture onto a photosensitive and pressure-sensitive paper, which comprises the steps of: forming in advance a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to information of the picture; exposing the photosensitive and pressure-sensitive paper through the mask original form to thereby form a latent image on the photosensitive and pressure-sensitive paper; and pressure-fixing the photosensitive and pressure-sensitive paper carrying the latent image formed thereon. Further disclosed is an apparatus for carrying out the above method, which comprises: a mask forming means for forming a mask original form of a film having a light-transmitting portion and a non-light-transmitting portion corresponding to picture information of an original picture; an exposure means for exposing the photosensitive and pressure-sensitive paper through the mask original form formed by the mask forming means; and a pressure-fixing means for pressing the photosensitive and pressure-sensitive paper having a latent image formed by the exposure means to thereby perform pressure-development.

An image forming apparatus may include a sheet conveying belt that conveys a sheet to a position opposed to an image carrier, and a cleaning unit that cleans the sheet conveying belt. The sheet conveying belt may be driven by a first driving unit such as a first motor while the cleaning unit may be driven a second driving unit such as a second motor. In one or more arrangements, the second driving unit is independent from the first driving unit. Additionally or alternatively, the first driving unit may also be configured to drive an image carrier and/or a developing unit.
摘要:
An image forming apparatus is swung with a stopper which is swingable simultaneously with a switching member, and which allows rotation of an output gear by being disengaged from the output gear with a swinging movement of the switching member to an ON side, and which stops the rotation of the output gear by being engaged with the output gear with a swinging movement of the switching member to an OFF side. When the switching member is swung to the OFF side, the stopper is engaged with the output gear at the same time as the switching member is disengaged from the triggering member or before the switching member is disengaged from the triggering member. Accordingly, a descent of a pressing plate at the time of stopping the pressing plate is prevented without using a one-way clutch.
