20100149289 | LIQUID APPLICATION MECHANISM AND INKJET RECORDING APPARATUS - A liquid application mechanism includes a liquid application unit that applies liquid to an application medium, and a liquid supply unit that supplies the liquid to the liquid application unit from a storage unit. The liquid supply unit recovers a portion of the liquid to the storage unit, the portion of the liquid being a portion that has been supplied to the liquid application unit and has not been applied to the application medium. At a bottom portion of the storage unit, a plurality of trap space sections separated from each other by ribs are formed. The trap space sections have continuous rectangular shapes, and are open upward in the direction opposite to gravity. The rib height of the trap space sections is equal to or greater than 3 mm, and the rib interval of the trap space sections is in the range from 2 mm to 10 mm. | 06-17-2010 |
20100295889 | INKJET PRINTING APPARATUS, LIQUID APPLICATION MECHANISM AND METHOD OF CONTROLLING THE LIQUID APPLICATION MECHANISM - Even if a liquid is attached and solidified on a peripheral surface of a coating roller, application of the liquid on a medium is uniformly performed. At least a part of contacting member is separated from the coating roller and the coating roller is rotated in a second direction as a reverse direction to a first direction to pull out the liquid from a liquid retaining space onto the coating roller. Next, by interrupting the above separation and rotating the coating roller in the first direction, a liquid reservoir is formed in the periphery of a contacting portion between the coating roller and the contacting member. | 11-25-2010 |
20110133397 | SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS - A sheet feeding apparatus including sheet feeding unit; a pressure plate on which sheets are stacked and which is biased so that an uppermost sheet of the stacked sheets comes in pressure contact with the sheet feeding unit; a first pressing-down mechanism which presses down the pressure plate to separate the uppermost sheet and the sheet feeding unit by a constant distance when the sheet feeding unit is not operated; a second pressing-down mechanism which is adopted to press down the pressure plate when an amount of the sheets stacked on the pressure plate is smaller than a predetermined amount, and is given a load from the pressure plate depending on a position of the pressure plate; and sheet stacking amount detecting unit which measures the load and detects a stacking amount of the sheets stacked on the pressure plate on the basis of the measured load. | 06-09-2011 |
20110140353 | SHEET FEEDING APPARATUS - A printer has a separating unit, such as a depressing cam and a depressing slider, which presses a middle plate against the biasing force of a spring and separates a sheet on the middle plate from a sheet feeding roller by a predetermined distance, a separation driving unit, such as a DC motor, which moves the separating unit, a measuring unit which measures the driving load applied to the separation driving unit when the separation driving unit drives the separating unit, and a load imparting unit, such as a brake plate, which imparts load to the middle plate, the separating unit, or the like. The brake plate or the like imparts load when a sheet is separated from the sheet feeding roller by the separating unit, and the brake plate or the like changes the load to be imparted, according to the turning angle of the middle plate. | 06-16-2011 |
20110140354 | RECORDING MEDIUM SUPPLY DEVICE AND RECORDING APPARATUS - A recording medium supply device includes a cassette attachable to and detachable from a main body and capable of stacking recording medium thereon, a feeding roller which feeds the uppermost recording medium to the main body from a leading end of the recording medium, a regulating member which is arranged forward in the direction in which the cassette is removed from the main body as seen from the feeding roller, and a projection preventing member attached adjacent to the tip portion of the cassette facing the leading end of the recording medium. The position of the lower end of the regulating member is higher than the cassette attached to the main body, and lower than the lower end of the feeding roller, and the position of the upper end of the projection preventing member is higher than the position of the lower end of the regulating member. | 06-16-2011 |
20130044159 | INK JET RECORDING APPARATUS - An inkjet recording apparatus includes a carriage with a recording head, a wiper holder that holds a wiper to wipe a discharge port surface of the recording head, a latch member arranged on the wiper holder that moves between a latch position where the wiper holder is held at a wiping position and a release position where the wiper holder is released, and a latch release member that moves the latch member from the latch position to the release position. | 02-21-2013 |
20130044161 | RECORDING APPARATUS AND CARRIAGE UNIT - A movable carriage unit on which a head for discharging ink is mountable includes a fixing member movable between a fixing position for fixing the head to a mounting position and a releasing position for releasing the fixation of the head, and a moving unit including an operation portion. The moving unit is configured to move the fixing member from the fixing position to the releasing position. A guide configured to guide the head to the mounting position when the fixing member is moved to the releasing position by an operation of the operation portion is formed on the operation portion. | 02-21-2013 |
20130207337 | RECORDING MEDIUM SUPPLY DEVICE AND RECORDING APPARATUS - A recording medium supply device includes a cassette attachable to and detachable from a main body and capable of stacking recording medium thereon, a feeding roller which feeds the uppermost recording medium to the main body from a leading end of the recording medium, a regulating member which is arranged forward in the direction in which the cassette is removed from the main body as seen from the feeding roller, and a projection preventing member attached adjacent to the tip portion of the cassette facing the leading end of the recording medium. The position of the lower end of the regulating member is higher than the cassette attached to the main body, and lower than the lower end of the feeding roller, and the position of the upper end of the projection preventing member is higher than the position of the lower end of the regulating member. | 08-15-2013 |
