The present invention provides a horizontally set recording apparatus provided with a sheet inserting and discharging holes at the upper surface, wherein substantially linear recording sheet transporting route passing through the recording section is formed, and an automatic sheet feeding apparatus can be removably attached thereon. The recording sheet is delivered into an inlet opening of said transporting route.

Recording apparatus

In an ink jet recording device having an ink tank integrated type jet recording head and a carriage for mounting the head thereon, good electrical connection is obtained wherein the electrical pad of the connecting terminal of the recording head and the electrical pad of the connecting terminal of the carriage are connected to each other while rubbing against one another. Further, also by specifying the arrangement position of the positioning member, more accurate electrical conduction is effected and also breaking of the positioning member is prevented, thereby providing an ink jet recording device having high reliability in aspects of both recording and durability.

Ink jet cartridge and ink jet recording apparatus

An ink jet cartridge has a recording head with a substrate, a head portion with a discharge port surface on the substrate, a discharge port provided on the discharge port surface, and an ink tank, the substrate having a leading end line. The ink tank has a substantially rectangular parallelopipedal shape and can contain ink. The ink tank includes a front surface, side surface, and opposing surface opposed to the side surface, the recording head is disposed on the side surface of the ink tank, and the opposing surface has a front end line. Plural positioning portions are provided on and project from the substrate of the head and part of the ink tank. The positioning portions project only within a space enclosed by a plane, the front surface of the ink tank, and the substrate. The leading end line of the substrate of the recording head and the front end line of the surface opposed to the side surface of the ink tank on which the recording head is disposed lie in the plane.

Ink jet cartridge having protected positioning portions

An ink jet recording apparatus wherein ink is ejected on a recording medium to effect recording includes a platen for regulating a recording surface of the recording medium; a confining member contactable to the platen to confine the recording medium; and an elastic member, disposed at a bottom of the apparatus, for urging the confining member to the platen.

Ink jet recording medium discharging mechanism including resilently

An ink jet recording apparatus has means for heating a recording medium guide member disposed near the ink recording area by a recording head for discharging ink, and means for changing the rate of heat imparted to the unit length of the recording medium with respect to the direction of conveyance thereof by the heating means in conformity with a parameter changing the environmental condition of the ink recording area.

Ink jet recording apparatus provided with fixating means

In a serial recording apparatus wherein a recording head is carried on a carriage movable in the direction of a print column and the recording head is driven on the basis of printing data while scanning by the recording head, to thereby form a dot image on a sheet, piezoelectric elements are joined to a vibration plate provided on the underside of the carriage and the vibration plate is slidably urged against the surface of a fixed member by a resilient force to thereby constitute a travelling wave type ultrasonic motor. A travelling wave is generated in the vibration plate by the piezoelectric elements being driven to thereby control the movement of the carriage.

Serial recording apparatus

A recording device wherein ink is deposited on recording materials to effect recording including first and second feeders for feeding the recording materials to a recorder, and a discharger for discharging the recording materials from the recorder such that the recording device can be placed horizontally and vertically in use. When the device is placed horizontally the recording materials are conveyed in a generally U-shaped path, and when the device is placed vertically the recording materials are conveyed in a generally rectilinear path.

A recording apparatus for effecting recording on a recording medium has a recording head for effecting recording on the recording medium, conveying rollers for conveying the recording medium, a first and a second case for covering the recording head and the conveying means, and a mechanism for effecting relative movement of the first case and the second case.

Compact ink jet recording apparatus with particular design for recording

A carriage, movable along a predetermined path, for detachably mounting thereon an ink jet recording head includes an abutment portion for positioning the recording head in a horizontal direction; an engageable member, disposed at a side of the carriage facing in a movement direction thereof, for engaging with the recording head, the engageable member is rotatable and translatable; and an operating lever, disposed at a side of the carriage facing in the movement direction, for translating and rotating the engageable member to abut the recording head to the abutment portion, and for rotating the recording head about the abutment portion; a second abutment portion for abutment with the rotating recording head to stop it in one rotational direction; and an urging member for urging the recording head to the second abutment portion, wherein the recording head is mounted on and dismounted from the carrier by moving the operating lever in one direction and by moving it in the opposite direction, respectively.

Ink jet recording head carriage and an apparatus with same

An ink tank for storing recording ink comprises an ink storage section including an ink holding member for holding ink and substantially entirely occupying an ink storage space and a ventilation section having a vent hole communicating with the interior of the ink tank with atmosphere, the ventilation section including an ink-repellent member having an ink-repellent character. The ink holding member can be formed of one porous member or two porous members, one of high and one of low porosity. The member with high porosity is provided adjacent an ink supply port. An ink jet recording head also comprises the same ink tank and an ink jet recording head section including an ink discharge port for discharging ink, an ink passage communicating with the ink discharge port and an energy generation element for generating energy utilized for ink discharged. Further an ink jet recording apparatus includes the same ink jet recording head.

A method of cleaning a discharge port surface of an ink jet recording apparatus includes wiping the surface using a blade having a certain contact area with the surface and rubbing the surface using a rubbing member having a larger contact area with the surface than the blade. The wiping and rubbing operations are performed independently of each other so that their different purposes can be better accomplished. For example, since rubbing the surface need not be done as often as wiping, they can both be performed at optimum intervals. The rubbing member can be removably mounted to a replacement ink cartridge so that the rubbing member can be conveniently replaced at the same time as the cartridge.

A recording apparatus including a body having a case, a first feeding device, a guide portion, a second feeding device, and a cover. The first feeding device feeds a record sheet to a recording position by frictional force. The guide portion guides a continuous record sheet supplied from a record paper source disposed outside of the apparatus. The second feeding device accepts the record sheet from the guide portion and feeds the record sheet to the recording position through the first feeding device. The second feeding device includes at least one pin which is adapted to engage a hole in the record sheet. The cover has a free end including a guide for guiding a non-continuous record sheet from outside the apparatus to the recording position through the first feeding device. The cover further has an engagement portion on the opposite end of the cover from the guide, for rotatably attaching the cover to the case.
