The sub roller 151 sandwiches the cut sheet with the driven rollers 152a, 152b, and 152c and reverses it into a U shape in order to discharge the cut sheet fed from the sheet feeding tray 201 to the sheet discharge tray 202. It is designed to be transported. The sub-roller 151 is configured to sandwich and convey the roll-shaped paper together with the driven roller 152c in order to eject the roll-shaped paper fed from the paper feeding unit 130 to the paper ejection tray 202. .

  The paper feed roller 153 sandwiches the cut paper that has been reversely conveyed or the roll-shaped paper that is fed together with the driven roller 154 and feeds it to the platen 163. The paper discharge roller 155 supports the paper passing through the platen 163 alone and discharges it onto the paper discharge tray 202. The detection sensor 157a detects the transport amount when the skew of the cut paper that is fed is taken. The detection sensor 157b is configured to detect a conveyance amount when cueing a cut sheet that is reversely conveyed or a roll-shaped sheet that is conveyed.

  In the recording unit 160, a carriage 161, a recording head 162, a platen 163, and the like are disposed. The carriage 161 is connected to a carriage belt (not shown). When the carriage belt is operated by a carriage driving device (not shown), the carriage 161 is entrained by the movement of the carriage belt and guided by a guide shaft (not shown) to reciprocate on the paper in the conveyance orthogonal direction. It is supposed to move. Furthermore, the carriage 161 is mounted with a recording head 162 that can eject ink droplets toward a lower sheet.

  The recording head 162 includes, for example, a plurality of black ink recording heads that eject two types of black ink, and a plurality of color inks that respectively eject six ink droplets of yellow, dark yellow, cyan, light cyan, magenta, and light magenta. Recording head. The recording head 162 is provided with a pressure generation chamber and a nozzle opening connected to the pressure generation chamber. The ink is stored in the pressure generation chamber and pressurized at a predetermined pressure to control the recording head 162 from the nozzle opening toward the sheet on the platen 163. Ink droplets of a specified size are ejected. The platen 163 supports and guides the paper transported from the paper feed roller 153 and the driven roller 154 toward the paper discharge roller 155 on the recording guide surface 163a which is the upper surface thereof.

  Next, details of the paper feed guide 210 and the paper discharge guide 220, which are characteristic parts of the present invention, will be described with reference to FIGS. The paper feed guide 210 includes a fixed guide member 211 that guides one side edge of the paper and a movable guide member 212 that guides the other side edge of the paper. The fixed guide member 211 is formed in a bar shape having an I-shaped cross section. Then, one end of the I-shape is fixed so as to be along one side end (the right end shown in FIG. 1) of the paper feed tray 201.

  The movable guide member 212 has an I-shaped cross section and is formed in a rod shape shorter than the fixed guide member 211. One end of the I-shape is along the other side end (left side end shown in FIG. 1) of the paper feed tray 201, and along the upper surface between the other side end and one side end of the paper feed tray 201 in FIG. It is arranged so as to be slidable in the c direction. Further, the movable guide member 212 is disposed such that the front end portion in the longitudinal direction is in the vicinity of the paper feed roller 142.

  The paper discharge guide 220 includes a fixed guide member 221 that guides one side edge of the paper and a movable guide member 222 that guides the other side edge of the paper. The fixed guide member 221 is formed in a bar shape with an L-shaped cross section. The L-shaped one end is fixed to the inside of the paper discharge tray 202, and the other end of the L-shaped is fixed along one side end (the right end shown in FIG. 1).

  The movable guide member 222 has a L-shaped cross section and is formed in a rod shape shorter than the fixed guide member 221. Then, one end of the L shape faces the inside of the discharge tray 202, that is, the direction facing the one end of the L shape of the fixed guide member 221, and the other end of the L shape is the other end of the discharge tray 202 (shown in FIG. 1 is provided so as to be slidable in the direction c in FIG. 1 along the upper surface between the other side end and one side end of the discharge tray 202. Further, the movable guide member 222 is disposed such that the front end portion in the longitudinal direction is in the vicinity of the paper discharge roller 155.

  The movable guide member 212 of the paper feed guide 210 and the movable guide member 222 of the paper discharge guide 220 are connected by a connecting member 230. The connecting member 230 is formed in a rod shape, and the upper end of the movable guide member 212 of the paper feed guide 210 and the paper discharge guide 220 are passed through a belt-like slit 202a formed in the paper discharge tray 202 and extending in the direction c of FIG. The lower end of the movable guide member 222 is connected. A connecting method using the connecting member 230 will be described with reference to the drawings.

  FIG. 4 is a diagram illustrating a connecting method using the connecting member 230. 4A, both ends of the connecting member 230 are always connected to the upper end of the movable guide member 212 of the paper feed guide 210 and the lower end of the movable guide member 222 of the paper discharge guide 220 by an adhesive, a claw, a screw or the like. An example is shown. In FIG. 4B, the connecting member 230 is divided into two, one connecting member 231 is formed with a telescopic connecting portion 231a, and the other connecting member 232 is formed with a hole 232a into which the connecting portion 231a can be fitted. Has been. The connecting member 231 is fixed to the upper end of the movable guide member 212 of the paper feed guide 210, and the connecting member 232 is fixed to the lower end of the movable guide member 222 of the paper discharge guide 220, and can be arbitrarily connected and detached. Is shown.

  4C, the lower end of the connecting member 230 is fixed to the upper end of the movable guide member 212 of the paper feed guide 210, the magnet 233 is fixed to the upper end of the connecting member 230, and the movable guide member 222 of the paper discharge guide 220 is fixed. A magnet 234 is fixed to the lower end. The movable guide member 212 of the paper feed guide 210 to which the coupling member 230 is fixed and the movable guide member 222 of the paper discharge guide 220 are coupled via magnets 233 and 234, and can be arbitrarily coupled and detached. ing.

  The magnets 233 and 234 may be arranged apart from each other as shown in FIG. In the example shown in FIGS. 4B and 4C, a paper feed cassette housing can be arranged instead of the paper feed tray 201. In this case, the paper feed tray 202 shown in FIG. A slit similar to the belt-like slit 202a extending in the c direction is also provided on the upper surface of the paper feed cassette casing.

  According to the paper feed guide 210 and the paper discharge guide 220 including the connecting member 230 having such a configuration, when the paper is set in the paper feed tray 201, the movable guide member 212 of the paper feed guide 210 is moved along the slit 202a. Since the movable guide member 222 of the paper discharge guide 220 can be set by sliding along the slit 202a at the same time as setting by sliding, the paper discharge trouble due to forgetting setting of the movable guide member 222 of the paper discharge guide 220 can be set. Can be prevented.

  Since the distance between the movable guide members 212 and 222 and the fixed guide members 211 and 221 can be freely changed, the width direction of the paper to be fed and ejected can be defined, and a paper feed such as a jam can be performed. Errors and paper discharge errors can be prevented. Further, since the movable guide member 222 and the fixed guide member 221 have L-shaped cross sections, the height direction of the discharged paper can also be defined.

  Furthermore, since the movable guide members 212 and 222 are provided compactly on the rear side of the paper feed tray 201 and the paper discharge tray 202, the operability of the movable guide members 212 and 222 can be kept good and the material cost can be reduced. In addition, the paper can be stably fed and discharged even when the inkjet printer 100 is inclined. A groove corresponding to the slit 202a is formed in the paper feed tray 201, and a protrusion that fits and slides in the groove is formed on the movable guide member 212, so that the movable guide members 212 and 222 can be interlocked more smoothly. be able to.

  An operation in the case of recording on a normal cut sheet with the ink jet printer 100 in such a configuration will be described. First, the cut sheets are stacked and stored in the paper feed tray 201 mounted on the paper feed / discharge unit 140, and the movable guide member 212 of the paper feed guide 210 is slid to move the cut paper in the width direction. It is sandwiched between the member 212 and the fixed guide member 211. At this time, the movable guide member 212 of the paper discharge guide 220 can be slid at the same time as the movable guide member 212 of the paper discharge guide 220 connected to the connecting member 230 can be slid. A paper discharge trouble due to forgetting to set 222 can be prevented.

  The cut sheet is pressed against the sheet feed roller 142 by the hopper 141 being raised by the restoration of the compression spring 144 in which the sheet bundle is mechanically synchronized with the rotation of the sheet feed roller 142, and only the uppermost cut sheet is separated. The paper is separated by the member 143 and fed to the transport unit 150. When the cut sheet to be fed reaches the contact point 151a between the sub roller 151 and the driven roller 152a, the cut sheet is skewed.

  This skew removing method is different depending on the sheet thickness. That is, in the case of a thin cut sheet of plain paper or less, the front end of the cut sheet is slightly bitten between the sub-roller 151 and its driven roller 152a, and then the rollers 151 and 152a are reversed and cut. By bending the cut paper, a method is adopted in which the front ends of the cut paper are aligned and the skew is removed.

  On the other hand, in the case of paper that has been cut thicker than plain paper, the leading edge of the cut paper is abutted against the contact point 151a between the sub-roller 151 and its driven roller 152a, and the paper feed roller 142 is slipped. A method of removing skew by aligning the leading ends of the paper is employed. The amount of biting and the amount of butting are detected by the detection sensor 157a, and the skew removal is controlled according to the detection amount.

  In this way, the skew removal method varies depending on the paper thickness because the thin cut paper is not stiff, and the paper feed roller 142 sends out the cut paper without slipping on the cut paper. This is because the thick cut paper has a structure in which the thin cut paper is bonded, and may peel off when the rollers 151 and 152a are reversed. is there.

  The cut sheet after skew removal is sandwiched between a sub-roller 151 driven by a paper feed motor (not shown) and its driven rollers 152a, 152b, and 152c and reversed in a U-shaped path, that is, in a direction opposite to the paper feeding direction. It is conveyed to. When the leading edge of the cut sheet reaches the detection position of the detection sensor 157b, cueing that is a recording start positioning of the cut sheet is performed.

  That is, the conveyance amount is detected by the detection sensor 157b until the leading edge of the cut paper reaches the cueing position from the detection position through the paper feed roller 153 and the driven roller 154, and according to this detection amount. Cueing is controlled. The conventional cueing is performed by the detection sensor 157a disposed on the upstream side of the sub-roller 151, but this cueing is performed by the detection sensor 157b disposed on the downstream side of the sub-roller 151. The amount can be reduced, and particularly the cueing error due to the paper thickness can be eliminated and the cueing accuracy can be improved.

  Thereafter, the cut sheet that has been cued is sandwiched between a paper feed roller 153 and a driven roller 154 that are driven by a paper feed motor (not shown) and conveyed to the recording unit 160. Accordingly, the nipping of the cut paper by the sub roller 151 and its driven rollers 152a, 152b, and 152c causes the conveyance accuracy to deteriorate, so that each of the driven rollers 152a, 152b, and 152c is released from the sub roller 151.

  The cut sheet conveyed is sucked and flattened on a platen 163 by a suction pump (not shown), and is recorded by a recording head 162 mounted on a carriage 161 scanned by a carriage motor and a timing belt (not shown). The control unit of the ink jet printer 100 supplies each color ink from a total of seven ink cartridges, for example, yellow, light yellow, magenta, light magenta, cyan, light cyan, and black, to the recording head 162, and discharge timing of each color ink. In addition, the driving of the carriage 161 and the paper feed roller 153 is controlled to execute highly accurate ink dot control, halftone processing, and the like. Then, the cut paper that has been recorded is pulled by a paper discharge roller 155 driven by a paper feed motor (not shown), discharged to the paper supply / discharge section 140, and stacked on the paper discharge tray 202. The

  In the above-described embodiment, the paper feed tray 201 is disposed on the lower side, and the paper discharge tray 202 is disposed on the upper side. However, the present invention can be similarly applied to an inkjet printer having a reverse arrangement. . In addition, the paper feed guide 210 is formed in an I-shaped bar shape, and the paper discharge guide 220 is formed in an L-shaped bar shape. It may be formed in a rod shape. The ink jet printer 100 that reverses when the paper moves from paper feed to paper discharge has been described, but the same applies to an ink jet printer that reversely feeds, that is, switches back when the paper moves from paper feed to paper discharge. Can be applied to.

  As described above, according to the ink jet printer 100 of this embodiment, the movable guide member 212 of the paper feed guide 210 and the movable guide member 222 of the paper discharge guide 220 integrated by the connecting member 230 are connected to the paper feed roller 142 and the movable guide member 222. Since it can be disposed in the vicinity of the paper discharge roller 155, that is, on the rear side of the paper feed tray 201 and the paper discharge tray 202, it is small in size, has high operability, and has low material cost. A paper guide 220 can be configured.

  Any recording apparatus provided with a medium supply tray and a discharge tray can be applied to, for example, a facsimile apparatus, a copying apparatus, and the like. In addition to the recording apparatus, the meaning of a liquid ejecting apparatus that ejects a liquid corresponding to its use from a liquid ejecting head onto an ejected medium instead of ink and attaches the liquid to the ejected medium is, for example, a liquid crystal display or the like Color material jet head used for manufacturing color filters, electrode material (conductive paste) jet head used for electrode formation for organic EL display and surface emitting display (FED), bio-organic matter jet head used for biochip manufacturing, precision pipette The present invention can also be applied to an apparatus equipped with a sample ejection head or the like.
