Abstract: 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.

Abstract: An ink jet recording method forms an ink jet image on a recording medium by serially moving an ink jet recording head having a plurality of ink discharge ports arranged in an array along a conveyance direction of the recording medium. The method includes the step of providing a platen having a planar section upstream in the conveyance direction and a slant section slanted downstream in the conveyance direction and in a direction parting from the ink discharge ports, opposed to an array of the ink discharge ports when the ink jet recording head serially moves. The method further includes the step of forming an ink jet image on the recording medium by ink discharge from the ink discharge ports when the ink jet recording head moves at least three times across a same area of the recording medium, a reverse side of which is supported by the platen.

Abstract: A recording apparatus capable of making the image formation without reduction in recording quality is embodied. The recording apparatus comprises holding means for detachably holding a recording head for forming image on the recording medium, and positioning means for positioning the recording head at a predetermined position of the holding means in mounting the recording head on said holding means, characterized in that the positioning means has a first fitting meand for restraining the recording head in a first direction, and a second fitting means for restraining the recording head in a second direction, wherein restraining means is provided for fitting the second fitting means prior to the first fitting means in mounting the recording head on the holding means.

Abstract: This invention provides a discharged ink treating method for destroying or dispersing ink deposit created on a discharged ink receiving portion side, by the use of a mechanically operated member. A method of treating discharged ink from an ink using portion using liquid ink has the step of destroying or dispersing ink deposit created in a discharged ink path along which the discharged ink passes from the ink using portion to a discharged ink receiving portion and on the discharged ink receiving portion side, by the use of a mechanically operated member.
