Abstract: A cap sheet metal (and pivot sheet metal) is configured to be able to move linearly with a cap arm (and an arm stay) via engagement between an engagement hole and a fitting shaft. Furthermore, the cap sheet metal (and the pivot sheet metal) can move pivotally with respect to the cap arm (and the arm stay) using the fitting shaft, which engages with the engagement hole, as a pivotal shaft. Thus, even if, for example, the direction of biasing toward the applying roller deviates or a positional relationship with the applying roller deviates slightly, the liquid holding member moves and pivots in the bias direction depending on the deviation. As a result, the contacting pressure of a contacting portion on the applying roller can be made uniform.

Abstract: An object of the present invention is to provide a liquid applying apparatus that enables the viscosity of a liquid to be applied and the condition of supply of the liquid to be detected using conventional mechanisms and without the need for a viscometer or the like, thus allowing prevention of improper application of the liquid to a medium and mitigation of wear of an applying roller or the like, the apparatus having an inexpensive configuration. Thus, according to the present invention, a driving load on an applying roller driving motor is detected when an applying roller is driven. If the driving load is equal to or more than a preset threshold, an operation of re-supplying the liquid is performed by a pump, or an operation of the roller driving motor is stopped.

Abstract: There is provided a liquid application apparatus capable of performing stable application without providing a new mechanism, by efficiently removing an application liquid increased in viscosity and fixedly adhered to an abutting portion between an application member and a liquid supplying member. A liquid application apparatus includes an application member that applies a liquid supplied to an applied face to a printing medium by rotating an application roller and a liquid holding member that abuts against the applied face to form a liquid holding space for holding the liquid, and the amount of liquid that is held in the liquid holding space and makes contact with the application member in unit time is larger before an applying operation for applying the liquid to the printing medium than in the applying operation.

Abstract: The invention is to provide a recording apparatus and a recording method, capable of automatically specifying a type of a recording medium by a simple and inexpensive structure, thereby automating a sheet type setting operation and avoiding an error of user in such sheet type setting operation. The apparatus is equipped with first detectors for detecting a width dimension of a recording medium, a second detector for detecting a surface characteristic of the recording medium, and a discriminator for discriminating the type of the recording medium based on the results of the first and second detectors.

Abstract: The recording paper is transported to a paper inversion unit in such a manner that, when recording of a first surface of a recording paper is performed, the recording paper is transported to a position where a rear end of the recording paper is released from a pair of sheet transport rollers, the sheet transport roller and a pinch roller are released at the position, the recording paper is transported in a direction opposite to the direction in the first surface recording to the pair of sheet transport rollers by a pair of sheet discharge rollers, the sheet transport roller is pressed against the pinch roller again, and the transport of the recording paper in the reverse direction is further continued.

Abstract: In both-side recording, wherein the fed recording sheet is conveyed to the recording portion and after the recording is executed on a face side surface, the recording sheet is conveyed to a sheet reversing portion where both sides are reversed, and is sent to the recording portion again where the rear side surface is recorded, a clearance between the recording head and the recording sheet can be changed when recording on the face side or the rear side surface. A first clearance suitable for the recording sheet having a standard thickness and material, and a second clearance greater than the first clearance, can be selected. When there is a possibility that the recording head can come into contact with the recording sheet due to influences from warping and the like, the second clearance is selected, and when there is less possibility of contact, a first clearance is selected.

Abstract: A recording apparatus is capable of reducing the operations to be executed by a user in a case of employing a thick recording sheet for a recording operation, thereby improving the operability of the recording apparatus. A thick sheet guide, which is mountable on the recording apparatus, is capable of assuming a first state for guiding a recording sheet in a case of supply of the recording sheet to a recording portion from a downstream side in a normal conveying direction, and a second state retracted from a conveying path in a case of conveying of the recording sheet in the normal direction. In the recording apparatus, a pinch roller is separated from a sheet conveying roller when a sensor detects that the thick sheet guide is shifted from the second state to the first state.

Abstract: In a recording apparatus including an inversion unit for inverting a recording sheet recorded on a side in a recording unit by conveying along a predetermined path and returning the recording sheet to the recording unit, the possibility of peeling of recording material from the recorded surface or re-deposition of the recording material onto the recording sheet can be reduced. The recording sheet subjected to recording on a side in the recording unit having a recording head is conveyed to the inversion unit, which includes, at a recorded side of the recording sheet, two both-side rollers which are driven and are formed of an elastic material, and, at a non-recorded side, two both-side pinch rollers which are formed of a non-elastic material. The inversion unit conveys the recording sheet along a turnaround path with the recorded side inside, thereby inverting and returning the recording sheet to the recording unit.

Abstract: When a both-side recording is executed by using a recording sheet where a warp has developed, a contact between a recording portion and the recording sheet is prevented, thereby obtaining a stable recording dignity. In both-side recording, wherein the fed recording sheet is conveyed to the recording portion and after the recording is executed on a face side surface, the recording sheet is conveyed to a sheet reversing portion where both sides are reversed, and is sent to the recording portion again where the rear side surface is recorded, a clearance between the recording head and the recording sheet can be changed when recording on the face side surface and when recording on the rear side surface. A first clearance suitable for the recording sheet having a standard thickness and a material, and a second clearance longer than the first clearance, can be arbitrarily selected.
