It is a space region formed between the front side wall surface.

  The conveyance path 37 communicates with a conveyance path 39 formed in front of the conveyance path 37. As for the conveyance path 39, one (upper) conveyance path wall surface is comprised by the lower surface in the structural member 12b of the apparatus main body 12, and the other (lower) conveyance path wall surface is comprised by the upper surface of the structural member 12a. Accordingly, the paper P sent out to the transport path 37 is transported to a transport path 39 communicating with the transport path 37, whereby a paper feed roller 65 as a pair of transport rollers rotatably supported by the apparatus main body 12. 66, and is conveyed to the recording unit 20. As a result, the driving roller 61 and the driven roller 63 that send the paper P to the transport path 37 function as a sending unit that sends the paper P to the recording unit 20. Thereafter, the paper P on which recording on the recording surface has been completed in the recording unit 20 is conveyed in the sub-scanning direction Y by a pair of paper discharge rollers 67 (only one is shown in FIG. 3) rotatably supported by the apparatus main body 12. And discharged from the outlet.

  Further, in the present embodiment, in the reversing unit 50, a conveyance path 38 as a paper conveyance path in addition to the conveyance paths 35, 36, and 37 is continuously formed from the conveyance path 37 to the lower rear side of the driving roller 61. The transport path 38 is used for reverse transport of the paper P when the recording apparatus 11 performs double-sided recording on the paper P. That is, the paper feed rollers 65 and 66 are rotated in the reverse direction by a drive source (not shown). By this reverse rotation, the sheet P is recorded on one side (front surface) in the recording unit 20 and then returned to the rear, which is the direction opposite to the sub-scanning direction Y, and a pair of rollers of the driving roller 61 and the driven roller 64. Is transported to the transport path 38 by being pinched by.

  In the transport path 38, one (lower) transport path wall surface is constituted by the upper surface of the frame member 57 and the front surface of the frame member 58, and the other (upper) transport path wall surface is the outer peripheral wall surface of the driving roller 61 and the width of the paper P. It is comprised by the frame member not shown formed in the direction both sides. In this conveyance path 38, for example, when recording is performed on both front and back sides of the paper P such as double-sided printing, the paper P is conveyed from the front to the rear.

  The recording apparatus 11 further includes a manual paper feed mechanism 40 in the reversing unit 50 in which the paper conveyance path is formed in this way. That is, the manual paper feed mechanism 40 joins the paper P (P2) inserted from the insertion port 42 in the middle of the transport path of the paper transport path, and passes the manual feed path having a common path with the paper transport path. Form. In other words, in the present embodiment, the manual feed path is in the middle of the transport path in the transport path 36 and communicates with the insertion port 42 on the upstream side in the transport direction with respect to the driven roller 63, thereby joining the transport path 36. To do. Therefore, the sheet P1 has a path on the downstream side in the transport direction in the transport path 36 after the merge, which is the same path as the transport path of the sheet P1. As a result, the insertion port 42 and the conveyance path 36a (see FIG. 5) on the downstream side in the conveyance direction after joining the conveyance path 36 correspond to a manual supply path. Further, in the present embodiment, the insertion port 42 in the manual feed path is formed in an oblique direction from the antigravity direction side to the gravity direction side, and above the curved shape of the transport path 36, the transport direction of the paper P1 and the paper Merges from an oblique direction in which the conveyance direction of P2 forms an acute angle with each other.

Next, operations (operations) of the recording apparatus 11 and the manual paper feed mechanism 40 in the present embodiment configured as described above will be described.
First, the operation of supplying the paper P1 from the paper feeding cassette 30 will be described with reference to FIG. 4, and then the operation of supplying the paper P2 by the manual paper feeding mechanism 40 will be described with reference to FIG. In the following description, components already described with reference to FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 4, when the paper P1 is supplied from the paper feed cassette 30, the paper P1 is sent from the paper feed cassette 30 to the transport path 35 by the paper feed roller 34 and rotated in the direction of the arrow in the figure. It is sandwiched between the roller 61 and the driven roller 62 and is conveyed from the conveyance path 35 to the conveyance path 36. In the conveyance path 36, it moves along the wall surface (lower surface) of the flap member 53 and a part of the wall surface (lower surface) of the flap member 54, and is sandwiched between the drive roller 61 and the driven roller 63 that function as a sending unit. As indicated by the arrow, the sheet is sent from the conveyance path 36 to the conveyance path 37.

  Thereafter, the sheet P1 moves from the conveyance path 37 to the conveyance path 39, and the leading end in the conveyance direction is the roller of the paper feed rollers 65 and 66 in a state where the nipping state between the driving roller 61 and the driven roller 63 is maintained. It is sent out to the recording unit 20 by being sandwiched between the pairs. Then, the fed paper P1 is transported in the sub-scanning direction Y in the recording unit 20. Accordingly, in the reversing unit 50, the paper P <b> 1 is transported from the transport paths 36 and 37 to the transport path 39 by the driving roller 61 and the driven rollers 62 and 63 until the paper P <b> 1 is sandwiched and transported by the paper feed rollers 65 and 66. Conveyed continuously. When double-sided recording is performed, as indicated by a two-dot chain line in the figure, the paper P1 is conveyed from the recording unit 20 in the reverse direction (broken line arrow in the figure) and sent out to the conveyance path 38. Then, the sheet P conveyed on the conveyance path 38 swings the frame member 58 around the rotation shaft 58a provided on the frame member 57, and is sent out again to the conveyance path 35, so that the conveyance path 36 has a curved shape. Is moved again by the rotation of the driving roller 61. In the movement in the conveyance path 36, the movement direction of the paper P is reversed from the rear to the front, and when it is sent again to the conveyance path 37, the front and back are reversed.

  Next, as shown in FIG. 5, when the paper P2 is supplied by the manual paper feed mechanism 40, the user opens the opening / closing lid 41 and inserts the leading end of the paper P2 into the insertion slot 42 that is exposed. Then, the leading end of the inserted paper P2 moves in the direction of gravity due to its own weight, the flap member 53 is pushed downward by the paper P2, and the gap between the flap member 53 and the flap member 54 is opened. An opening is formed in which the conveyance path 36a corresponding to the space area portion on the downstream side in the conveyance direction and the insertion port 42 communicate with each other.

  The insertion port 42 is formed in an oblique direction from the antigravity direction side to the gravity direction side. Then, the insertion port 42 and the conveyance path 36 are arranged so that the paper P2 inserted from the insertion port 42 enters the conveyance path 36 from a direction that makes an acute angle with the conveyance direction of the paper P1 conveyed in the conveyance path 36. It merges through the formed opening.

  Accordingly, the paper P2 inserted into the transport path 36 (transport path 36a) from the insertion port 42 through the formed opening is inserted into the transport path 36 obliquely with respect to the transport path 36, so that the transport path It smoothly enters the conveyance path 36 without being caught on the wall surface 36. In the conveyance path 36, it moves between a part of the wall surface (lower surface) of the flap member 54 and the driving roller 61, and is sandwiched between a pair of rollers of the driving roller 61 and the driven roller 63 that function as a sending unit. Sent out.

  Thereafter, as indicated by a two-dot chain line in the figure, the sheet P2 moves from the conveyance path 37 to the conveyance path 39, and is nipped between the driving roller 61 and the driven roller 63, and the leading end in the conveyance direction is fed to the paper. By being sandwiched between the rollers 65 and 66, the recording unit 20 is transported in the sub-scanning direction Y. In other words, the length L in the transport direction of the paper P2 supplied by the manual paper feed mechanism 40 is determined by the transport between the driving roller 61 and the driven roller 63 and the transport between the paper feed rollers 65 and 66. However, it is possible to transport a short sheet having at least a length that is performed simultaneously. Of course, when double-sided recording is performed on the paper P2, the paper P2 is conveyed in the reverse direction from the recording unit 20, and has a length that can be conveyed again to the conveyance path 35 via the conveyance path 38. Have.

  6A and 6B show the operation in the recording apparatus 11 of the present embodiment in which the sheet conveyance path is formed in the reversing unit 50 that is a detachable member that can be attached to and detached from the apparatus main body 12, that is, jam processing. Will be described with reference to FIG.

  As shown in FIG. 6A, when the paper P jammed in the paper transport path is to be jammed, the operator pulls the reversing unit 50 rearward and removes it from the apparatus main body 12. The reversing unit 50 is pulled out of the apparatus main body 12 by releasing the locked state to the apparatus main body 12 by sliding the operation portion 50 a formed on the frame member 52. By pulling out the reversing unit 50, the space area SP occupied by the reversing unit 50 is exposed in the apparatus main body 12. Therefore, the operator inserts his / her hand into the formed space region SP while visually checking the paper P in the jammed state in the conveyance path 39 and the paper feed rollers 65 and 66 in the exposed space region SP. Processing can be performed. Of course, the operator inserts and installs the reversing unit 50 in the apparatus main body 12 after the jam processing.

  Alternatively, when the paper P is jammed in the paper conveyance path formed in the reversing unit 50, the reversing unit 50 is pulled out from the apparatus main body 12 to perform jam processing. For example, as shown in FIG. 6B, the paper P that is jammed in the conveyance path 37 is exposed in a state in which the reversing unit 50 is pulled out from the apparatus main body 12, so that the operator is in the jammed paper. Jam processing can be performed while viewing P. Of course, the paper P that is jammed in the transport path 36 and the transport path 35 can be similarly processed.

According to the above embodiment, the following effects can be obtained.
(1) The paper P2 is used by utilizing the weight of the paper P2 with respect to the paper transport path normally used when the paper P1 placed in the paper feed cassette 30 is transported and inserting the paper P2 obliquely. Can be smoothly inserted into the normal sheet conveying path from the manual feed path. Accordingly, the paper P2 can be smoothly supplied to the recording unit 20 in the same manner as the paper P1.

(2) The manual feed path and the sheet conveyance path can be easily merged by the component of the conveyance path that is displaced on the outer side surface of the conveyance path 36 that is a curved path.
(3) When the paper P2 is not supplied to the recording unit 20, the paper P1 can be smoothly transported along the transport path 36 by closing the manual feed path.

  (4) Since the gap between the flap member 53 and the flap member 54 is opened by being pushed by the paper P2, the manual feed path can be opened by the leading end portion of the paper P2 moving by its own weight. Accordingly, the paper P2 can be smoothly inserted into the paper transport path.

  (5) A short length corresponding to the distance between the drive roller 61 provided in the paper conveyance path normally used when the paper P1 is conveyed and the paper feed rollers 65 and 66 that supply the paper P to the recording unit 20 Even the paper P2 can be smoothly supplied to the recording unit 20.

  (6) The opening / closing lid 41 can prevent foreign matter other than the paper P2 from entering the insertion port 42 (manual supply path). Further, the appearance can be improved by covering the insertion port 42.

  (7) Since the paper transport path is formed in the reversing unit 50 that can be attached to and detached from the recording apparatus 11, even if the paper P2 is jammed in the paper transport path, such a paper transport path itself is reversed. Since it is detached from the recording apparatus 11 as a part of the unit 50, the jammed paper P2 can be easily removed and jammed.

(8) The recording apparatus 11 that can smoothly supply the paper P2 to the recording unit 20 in the same manner as the paper P1 conveyed from the paper feed cassette 30 can be provided.
In addition, you may change the said embodiment as follows.

  In the above embodiment, the sheet conveyance path does not necessarily have to be formed in the reversing unit 50 that can be attached to and detached from the recording apparatus 11. For example, the recording apparatus 11 in which the reversing unit 50 is not attached to or detached from the apparatus main body 12 may be used. Alternatively, apart from the reversing unit 50 to be attached and detached, a paper conveyance path where the manual feed path joins may be formed in the apparatus main body 12.

  In the above embodiment, the recording apparatus 11 may not have a function of recording on both the front and back sides of the paper P. In this case, the detachable member may be a member other than the reversing unit 50. For example, in the case of a recording apparatus having a configuration that does not reverse the paper P, a conveyance path forming member that constitutes a conveyance path may be provided in a portion corresponding to the reversing unit 50, and the conveyance path forming member may be attached and detached.

  In the above-described embodiment, an opening / closing lid 41 that covers the insertion port 42 so as to be openable / closable is not necessarily provided at the upstream end in the conveyance direction of the paper P2 conveyed through the manual feed path, that is, the upstream end of the insertion port 42. It does not have to be.

  In the above embodiment, the paper conveyance path does not necessarily have to join the conveyance path 36 from an oblique direction that forms an acute angle with respect to the conveyance path 36 that is conveyed while the paper P1 is curved. For example, a right angle may be used as long as the sheet P2 is smoothly conveyed.

  In the above embodiment, the manual feed path does not necessarily have to merge with the paper transport path on the upstream side in the transport direction with respect to the roller pair of the driving roller 61 and the driven roller 63. For example, when the paper P2 can be conveyed in a state where the bending is suppressed by the conveyance path 36 and the conveyance path 37, there is no problem even if the feeding unit does not exist on the downstream side in the conveyance direction after merging.

  In the above embodiment, the loading medium and the manual feeding medium are not limited to paper, and may be a plate-like member made of a metal plate, a resin plate, a cloth, or the like. That is, any member that can be transported along the transport path and can be recorded by the recording unit 20 can be used as a mounting medium and a manual feeding medium.
