Abstract: In an inkjet recording apparatus, a recording head has an ink ejection port through which ink is ejected, a cleaning liquid supplying portion has a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface having the ink ejection port, is supplied, and a cleaning member cleans the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface. The cleaning liquid supplying portion includes a main body portion and a protruding portion. The main body portion is disposed on an upstream side of the recording head in a moving direction of the cleaning member. The protruding portion protrudes from the main body portion toward a downstream in the moving direction, and covers, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.

Abstract: A head cleaning mechanism of the disclosure includes a recording head and a wiper. The recording head includes an ink ejection surface in which an ink ejection area with a plurality of ink ejection ports opened therein is provided. The wiper wipes the ink ejection surface in a specified direction. The recording head includes an inclined surface placed on an upstream side of the ink ejection surface in a wiping direction that is a direction in which the wiper wipes the ink ejection surface, the inclined surface being inclined downward toward a downstream side of the wiping direction. A plurality of cleaning liquid supply ports for supplying cleaning liquid are provided on a wiping-direction upstream side of a position in the inclined surface with which the wiper makes contact during wiping operation.

Abstract: A head cleaning mechanism includes a recording head and a wiper. The recording head has an ink ejection surface in which ink ejection ports are opened. The wiper wipes the ink ejection surface. The recording head has a cleaning liquid supply ports disposed on an upstream side of the ink ejection port in a wiping direction, and an inclined surface inclined downward toward a downstream side in the wiping direction, a tip of the wiper being in pressure contact with the inclined surface in the wiping operation. The inclined surface has a pressure contact start position at which the wiper starts the pressure contact in the wiping operation, and a water repellent region formed at least from the pressure contact start position to a position on an upstream side of the cleaning liquid supply port in the wiping direction.

Abstract: Provided is a recording head recovery system, which includes a recording head and a wiper. The recording head includes an ink ejection surface provided with an ink ejection region in which ink ejection ports are formed. The recording head is disposed on a wiping direction upstream side of the ink ejection region, and a cleaning liquid supply region in which cleaning liquid supply ports for supplying cleaning liquid are formed. A height position of a lower end part of the wiper when passing the cleaning liquid supply region is lower than a height position of the lower end part of the wiper when wiping the ink ejection region.

Abstract: A recording head is provided with an ink ejection surface and a cleaning liquid supply surface. The ink ejection surface includes a nozzle region in which a plurality of ink ejection nozzles for ejecting ink onto a recording medium are open. The cleaning liquid supply surface is provided, with respect to the nozzle region, on an upstream side in a wiping direction in which a wiper wipes the ink ejection surface, and a plurality of cleaning liquid supply ports for supplying a cleaning liquid are open through the cleaning liquid supply surface. On the cleaning liquid supply surface, at least in a region including the cleaning liquid supply ports, a hydrophilic region having wettability with respect to water higher than that of the ink ejection surface is formed substantially evenly across an entire region in a width direction thereof orthogonal to the wiping direction.

Abstract: A recording head recovery system has a recording head, a tank, and a control portion. The control portion can perform a recovery operation of the recording head including a cleaning solution feeding operation where cleaning solution is fed through cleaning solution feed ports by locating the tank such that the solution surface of the cleaning solution in the tank is above a first position which is the height of the cleaning solution feed ports, a wiping operation where a wiper wipes an ink ejection surface, and a non-feeding operation where the cleaning solution is sucked into the cleaning solution feed ports by locating the tank such that the solution surface of the cleaning solution in the tank is below the first position.

Abstract: In an inkjet recording apparatus, a recording head has an ink ejection port through which ink is ejected, a cleaning liquid supplying portion has a cleaning liquid supply port through which cleaning liquid for cleaning an ink ejection surface having the ink ejection port, is supplied, and a cleaning member cleans the ink ejection surface by the cleaning liquid by moving while in contact with the ink ejection surface. The cleaning liquid supplying portion includes a main body portion and a protruding portion. The main body portion is disposed on an upstream side of the recording head in a moving direction of the cleaning member. The protruding portion protrudes from the main body portion toward a downstream in the moving direction, and covers, from below, lower ends of side surfaces of the recording head and the main body portion that face each other in the moving direction.

Abstract: An inkjet recording apparatus includes an ink ejection surface and a cleaning liquid nozzle. The ink ejection surface has an ink ejection port through which ink is ejected. The cleaning liquid nozzle has a cleaning liquid supply port through which cleaning liquid for cleaning the ink ejection surface is supplied. In the cleaning liquid nozzle, a concave meniscus is formed on a surface of the cleaning liquid.

Abstract: There is provided an operation mechanism including an operation part that is slidable with respect to a fixed part, a plurality of operation-feeling generating members configured to generate different operation feelings on the operation part, and a switching part configured to switch the plurality of operation-feeling generating members independently from each other to switch to one of the operation-feeling generating members that is to act on the operation part.
