There is provided an ink-jet recording apparatus which includes a recording portion, and a contact portion configured to come into contact with an upper surface of the sheet. The contact portion has a storage portion provided on a side of the recording portion and configured to store an ink, and a protruding portion provided between both ends in a width direction intersecting the transporting direction of the storage portion, and which is protruded toward the recording section, and an upper end of the protruding portion is the highest in the contact portion.

Ink-jet recording apparatus

An image forming apparatus may include a mechanism for forming a corrugated shape in a sheet to be conveyed. The mechanism may include various components include one or more pressing portions, one or more ribs, one or more discharge rollers, a switching mechanism and the like. In one arrangement, ribs and pressing portions configured to create the corrugated shape may be disposed at various locations upstream or downstream of the platen, recording portion and/or nozzles thereof. In one example, pressing portions may be disposed both upstream and downstream of the nozzles of the recording portion to maintain a corrugated shape in the conveyed sheet. Various other configurations may be used.

Inkjet recording apparatus

There is provided an image recording apparatus including a transporting path, a recording section, a first and second rollers pinching the recording medium therebetween, a supporting member which rotatably supports the second roller, a holding member which is movable along a transporting direction of the recording medium, a bias applying member which applies a bias on the holding member, in an opposite direction opposite to the transporting direction and a load member which generates a load in the opposite direction, with respect to the recording medium.

Ink-jet printer

An image recording apparatus includes a recording unit configured to record an image on a sheet conveyed in a conveyance direction; a first wavy shape applying mechanism provided downstream in the conveyance direction from the recording unit and configured to allow the sheet to be in a wavy state in a width direction; and a guide member configured to guide the sheet to the first wavy shape applying mechanism. The first wavy shape applying mechanism includes first spur rollers configured to abut against a first surface of the sheet respectively; abutment members provided between the mutually adjoining first spur rollers respectively and configured to abut against a second surface of the sheet; and second spur rollers configured to abut against the first surface of the sheet downstream of the first spur rollers in the conveyance direction.

Image recording apparatus

There is provided a sheet tray including: first, second and third trays. The second tray moves between a first position and a second position in which an overlapping area is smaller than that obtained in the first position. The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

Sheet tray, conveyance unit and image recording apparatus

There is provided a sheet conveyance apparatus, including: a casing; a sheet support unit including a first surface inclined to a placement surface; a separation unit arranged in the sheet support unit on a side of the placement surface and abutting against edges of the sheets supported by the first surface; a first plate member including a second surface arranged in the sheet support unit on a side opposite to the separation unit and faces in the same direction as the first surface; and a feed unit which feeds the sheet supported by the first surface and the distal end of the second surface to the conveyance path while slidably moving the sheet with respect to the separation unit.

Sheet conveyance apparatus and image recording apparatus

A sheet tray includes a first tray and a second tray each including a first friction portion or a first contact portion, and a second friction portion or a second contact portion. In a process of movement of the second tray from a first position to a second position, the first friction portion contacts the first contact portion to deform the first contact portion and starts returning the first contact portion from a deformed shape to an original shape when the second tray is located at a position spaced apart from the second position in a second direction. The second friction portion contacts the second contact portion when the second tray moved from the first position in a first direction has reached the second position, and the second friction portion deforms the second contact portion when the second tray is moved from the second position in the first direction.

Sheet tray

A first roller is driven, by a conveying motor rotating in a normal direction and in a reverse direction, to rotate in a forward direction and in a backward direction, respectively. The first roller and a second roller convey a sheet in a conveying direction by rotating in the forward direction. The transmission unit transmits a driving force of the conveying motor to the second roller and includes a first rotary member. The transmission unit has such play that when the conveying motor is switched from rotation in a normal direction to rotation in a reverse direction, rotation of the second roller in a backward direction is delayed by a predetermined time period from rotation of the first roller in the backward direction. The predetermined time period is greater than a time period corresponding to one tooth of the first rotary member.

There is provided a feed apparatus including: a support unit supporting a sheet; a feed roller; a first arm; a recess portion; a second arm; a biasing member; an operation lever; and an engagement portion. The engagement portion is configured to be separated from the second arm at the first position in a case that the feed roller abuts against the support surface. The engagement portion is configured to be engaged with the second arm in a case that the first arm swings in a direction in which the feed roller is separated from the support surface. The second arm is configured to swing from the first position to the second position in conjunction with swing of the first arm in a direction in which the feed roller is further away from the support surface.

Feed apparatus and image recording apparatus

An image recording apparatus includes: an apparatus casing in which a transport path for transporting a sheet is formed; a first sheet support unit having a first support surface configured to support the sheet; a feed unit configured to feed the sheet supported by the first support surface to the transport path; a second sheet support unit having a second support surface configured to support the sheet; a transport unit configured to transport the sheet from the first and second sheet support units via the transport path; and a recording unit configured to record an image on the sheet transported by the transport unit in the transport path. The first and second sheet support units are arranged on one side surface of the apparatus casing, and the first and second support surfaces are configured to incline with respect to a placement surface on which the apparatus casing is placed.

There is provided a conveyance apparatus including: a conveyance roller; a plurality of driven rollers; a plurality of roller holders; an biasing member biasing each of the roller holders toward a first position; and a movable member having a plurality of cam portions. Each of the cam portions has: a first inclined surface abutting against one of the roller holders from a side of one of the driven rollers, during a movement process of the movable member from a third position to a fourth position, to thereby move one of the roller holders from the first position toward a second position; and a second inclined surface arranged upstream of the first inclined surface in a moving direction, and abutting against one of the roller holders from the side of one of the driven rollers, during the movement process of the movable member from the third position to the fourth position.
