A recording apparatus for recording on a recording medium comprises a movable recording member facing a recording medium to record on said recording medium by serially moving with respect to the recording apparatus main body; a movement mechanism for serially moving said movable recording member; and plural flexible members for connecting the movable recording member and the recording apparatus main body, which are connected with the movable recording member from the sides opposite to each other with the movement path of the movable recording member between them, hence making it possible to reduce the influence on the positional precision of the movable recording member and the movement precision thereof as well, which is exerted by force given to the movable recording member by the flexible members.

Recording apparatus

An image recording apparatus comprises a roller, and a bearing fixed to the apparatus main body to rotatably support the roller through the shaft portion of the roller. The bearing is provided with at least two contact portions to be in contact with the shaft portion of the roller, and the shaft portion of the roller is biased to each of the contact portions. With the structure thus arranged, it becomes possible for this apparatus to enhance the sheet conveyance precision or to make the roller smaller at lower costs.

Image recording apparatus

A recording member feeding device feeds a recording member such as a sheet in an image recording apparatus such as a copying machine. The recording member feeding device has a feeding rotary unit, a driving unit for driving the feeding rotary unit, and a driving power transmitting unit for transmitting he power of the driving unit to the feeding rotary unit. The recording member feeding device further has a rotation detecting unit for detecting the number of rotations of a rotary part in the rotary driving unit or in the driving power transmitting unit. The feeding rotary unit feeds the recording member by a length which is determined by the number of complete rotations detected by the rotation detecting units.

An ink jet recording apparatus comprises a recording area where a recording sheet is conveyed substantially in a horizontal direction to a position opposite to a discharge port for discharging ink, and recording is performed by discharging ink from the discharge port downwardly substantially in a vertical direction to the recording sheet and a sheet-exhausting area where the recording sheet is conveyed from the recording area and exhausted. The sheet-exhausting area has a first sheet conveyor for introducing the recording sheet from the recording area to the sheet-exhausting area and a second sheet conveyor for holding the recording sheet introduced from the recording area to the sheet-exhausting area by the first sheet conveyor substantially in the horizontal direction or above the substantially horizontal direction and exhausting the recording sheet substantially in the horizontal direction or above the substantially horizontal direction.

Ink jet recording apparatus

In a serial recording apparatus having three recording modes, i.e., normal, high-quality, and high-speed recording mode, sheet feed control satisfying requirements in these modes is performed. More specifically, high-speed sheet feed control is performed in the normal or high-speed recording mode, and low-noise sheet feed control with improved precision is performed in the high-quality recording mode although the speed is low.

An ink jet recording apparatus for discharging ink from a recording head to a recording material to thereby effect recording has a contacting member for cleaning the discharging surface of the recording head. The contacting member is rotatable until immediately before it contacts with the discharging surface, and the rotation of the contacting member is fixed when the contacting member contacts with the discharging surface.

Ink jet recording apparatus provided with an improved cleaning mechanism

An ink jet recording apparatus, which forms images on a recording medium using an ink jet recording head to discharge ink onto the medium to record the image. The recording material is carried and ink mist generated at the time of image recording flows along an air path in a specific direction. Electric field formation members arranged for the wall faces of the air path. With the structure thus arranged, effective mist collection is possible Without making the pressure loss of the air flow unduly large. stains that would otherwise result in the interior of the recording apparatus can be prevented, hence avoiding the deposition of ink mists on parts that may cause the defective operation particularly due to the deposition of such stains. Then, it becomes possible to record images stably for a long time, and the reliability of the ink jet recording apparatus is enhanced significantly.

An ink jet recording apparatus for recording onto a recording medium using an ink jet recording head which discharges ink, comprises a conveyor which conveys a recording medium, a mount for mounting an ink jet recording head, and an air flow generator. The air flow generator generates an air flow for transporting ink mist generated when ink is discharged from the ink jet recording head, floating in the inside of the ink jet recording apparatus and unused for recording. The head mount mounts the recording head such that ink is discharged toward a recording region located downward of the head mount, and is arranged forwardly of supporting members that support the head mount, and the air flow generator forms an air flow directed downwardly from above and forwardly of the supporting members.

Precision of detecting existence/non-existence of a liquid container and a liquid level in the container is improved even if the detection is performed by a single sensor, or even if the S/N ratio of the detection is low, the detected results can be discriminated from one another. For this, a concave polyhedron is provided in the center of the bottom surface of an optical prism in order to reduce the amount of light reflected on the bottom surface of the optical prism and returned to a photoreceptor. Moreover, a reflection curved surface having a quadratic surface e.g. spherical surface or paraboloid, is provided on the bottom surface of an ink tank, for reflecting light emitted by an optical unit consisting of a light emission device and a photoreceptor. By virtue of this, even in a case where an arrangement angle or position of the optical unit is deviated to some extent, sufficient amount of light for the photoreceptor can be received, making it possible to accurately detect existence/non-existence of ink and/or existence/non-existence of an ink tank.
