Abstract: A recording apparatus includes: a recording unit that performs recording on a recording medium wound on a roll, the roll including a first flange that is attached to one end and has a shaft hole and a first receiving portion, and a second flange that is attached to the other end and has a shaft hole; a first holder movable along a rotation axis of the roll, the first holder including a first shaft insertable into the shaft hole in the first flange, and a first flange-support surface that is in contact with an outer periphery of the first flange to support the first flange when the first shaft is not fitted in the shaft hole in the first flange and that has a first engaging portion; a second holder including a second shaft insertable into the shaft hole in the second flange.

Abstract: A roll medium supporting apparatus includes: a base body portion to be inserted into a hollow shaft portion of a rolled medium; a plurality of contact supporting portions provided circumferentially of the base body portion so as to be capable of being displaced radially of the hollow shaft portion, having a plurality of predetermined positions within the displaceable range, and coming into contact with the inner peripheral surface of the hollow shaft portion and supporting the same; and a stabilizing mechanism configured to stabilize the contact supporting portions at the plurality of predetermined positions.

Abstract: A recording apparatus has a recording head, a platen, and a first hole. The recording head includes a dot formation element array, and the platen holds a recording medium opposite the recording head. The first hole is disposed in an area of the platen opposite a downstream portion of the dot formation element array and guides ink discarded outside an end of the recording medium when the end is printed without a margin. Alternatively or additionally, a second hole is formed in an area of the platen opposite an upstream portion of the dot formation element array, and the platen guides ink, which is discarded outside an end of the recording medium when the end is printed without a margin, to the second hole.

Abstract: A recording head has a dot formation element array including a pluarlity of dot formation elements arranged in a first direction. A platen is operable to hold a recording medium in a position opposite to the recording head. The platen has a hole formed in a substantially center area in the first direction of the platen.

Abstract: A sheet feeding device is adapted to feed a recording medium including a first medium provided as a cut-sheet form and a second medium provided as a rolled-sheet form to a recording section at which a recording operation is performed with respect to the recording medium, by ejecting ink droplets thereto. A first sheet feeder is operable to feed the first medium stacked thereon to the recording section. A second sheet feeder is adapted to be detachably attached the first sheet feeder, and operable to feed the second medium to the recording section.

Abstract: An auxiliary roller is disposed in the proximity of sides of feed rollers and in the proximity upward from a separation pad. At the print time, the auxiliary roller is slightly projected toward the side of print sheet from roller faces of the feed rollers. The auxiliary roller is displaced as paper is displaced in a stack direction of the paper, and can be freely rotated. A hopper is moved up, paper is pressed against the feed rollers, and the separation pad abuts the feed rollers. Then, the feed rollers and a transport roller are rotated forward for feeding the paper to the transport roller. Further, the paper is sent from the transport roller at a distance equal to or greater than the length along the feeding path between the position of the front end of paper placed in a paper feed tray and the abutment center point of the separation pad and the feed rollers. Subsequently, the feed rollers and the transport roller stop, the hopper is moved down, and the separation pad is brought away from the feed rollers.

Abstract: Springs 34 and 35 are located on the back face of a paper cassette, between a movable plate 32 and a bar 31, coupled with a side edge aligner 27. A slot extending in the direction in which a spring load is generated is formed in the movable plate, and a hook portion is formed at the end of the spring in the direction in which the spring is extended or contracted. The length of the slot and the length of the spring end in the direction in which the spring load is generated differ for the individual springs, and correspond to the distance the movable plate is displaced. That is, a size difference is defined for each spring until the spring load is applied. During the insertion of the paper cassette, the movable plate is displaced by the mechanism constituted by the groove cam 41 and the boss 36a, and in accordance with the displacement, different spring loads are multiply applied the paper side edge aligning member via the bar.

Abstract: A mechanism for selectively switching two drive transmission systems by one driving source is provided and a rocking lever which can be rocked between a first drive transmission gear of a first drive transmission system and a first drive transmission gear of a second drive transmission system respectively located on both sides of a drive shaft is provided. A rocking gear located between both drive transmission gears and selectively engaged with both drive transmission gears for transmitting driving force from the driving source is attached to the rocking lever and a locking means mocks the rocking lever in a state that the locking means is engaged with either of the both drive transmission gears. The first drive transmission system and the second drive transmission system are connected to a drive unit normally and reversely rotated. At least one flat side is formed in the above locking means and a flat side which can come in contact with the flat side of the locking means is formed in a fitting part.
