摘要:
A recording apparatus is capable of preventing both contamination on a recording surface due to a contact of a recording medium on an ink discharging surface even when recording on the recording medium with a concave/convex portion and an ill-discharged state of an ink. The recording apparatus has a feeding unit for feeding a recording medium and a recording head as a recording unit for recording an image on the recording medium fed by the feeding unit. A first guide member (shaft) and a second guide member that serve as a correcting mechanism are provided upstream in a feeding direction from the recording head, for correcting the concave/convex portion of the recording medium.

An ink jet recording apparatus for recording on a recording medium using an ink jet recording head that records by discharging ink from ink discharge ports thereof. The ink jet recording apparatus includes a carriage that carries the ink jet recording head and reciprocally moves the head in a manner such that the recording head is opposite the recording medium, and the carriage includes a temperature stabilization portion contactable with the ink jet recording head carried on the carriage, wherein the temperature stabilization portion radiates heat generated by the ink jet recording head.

The present invention provides an image recording apparatus with an image recording unit for recording an image on a recording medium, a first conveyor for conveying the recording medium to an image recording portion of the image recording unit while bending the recording medium along a drive convey roller by means of the drive convey roller, and a second conveyor for conveying an elongated recording medium having a plurality of pin holes to the first conveyor. A guide capable of changing a contact area between the recording medium and the drive convey roller at a curved portion of the recording medium along the drive convey roller is also provided.

The present invention provides a sheet conveying apparatus for conveying a sheet comprising a convey member for applying a conveying force to a sheet, a drive source for driving the convey member, and a drive transmitting means for transmitting a drive force from a first drive transmitting member attached to the drive source to a second drive transmitting member attached to the convey member through one or more speed reduction members stepwisely. Among the first drive transmitting member, second drive transmitting member and speed reduction members, manufacturing accuracy of the speed reduction member disposed at a front stage of the second drive transmitting member is greater than manufacturing accuracies of the other members.

The present invention relates to a sheet supplying apparatus for selecting and supplying a sheet from a plurality of sheet supply portions. Each of the sheet supply portion comprises a sheet supporting means for supporting the sheets, a rotatable sheet supply means for feeding out the sheet supported by the sheet supporting means, a drive source for driving the rotatable sheet supply means, a drive transmitting means for transmitting or not transmitting a driving force of the drive source to the rotatable sheet supply means, and a control means for controlling the transmission and non-transmission of the drive transmitting means.

According to an image forming apparatus, a simple arrangement is used to switch the transmission of drive forces, produced by drive sources that are used in common by multiple drive mechanisms, without depending on the movement of a carriage, for example. The drive force produced by a line feed (LF) motor to drive feed rollers is transmitted to a pump cam in a recovery system via a pendulum drive force transmission mechanism, which is provided at one end close to the feed rollers. And the drive force produced by another motor to drive paper supply rollers is transmitted via the same pendulum drive force transmission mechanism to the paper supply rollers, or to a blade holder and a cap holder in the recovery system. Therefore, the transmission of the drive forces can be switched by controlling the rotational directions of the motors.
摘要:
A recording apparatus which includes a first and second discharge members located downstream from a recording head for discharging a sheet, and first and second auxiliary discharge members also located downstream from the recording head for discharging the sheet, where the first and second auxiliary discharge members are urged against the first and second discharge members, respectively, at a first position, and where the first auxiliary discharge member is substantially urged against the second discharge member at a second position.

A recording apparatus includes a head set lever which fixes a head cartridge to a carriage section. The head set lever is movable between a first position at which the head cartridge is fixed to the carriage section and a second position at which mounting and removal of the head cartridge on and from the carriage section is permitted. Attachment of an ink tank to the head cartridge is inhibited when the head cartridge is mounted on the carriage section and the head set lever is arranged at a position other than the first position.
