A drive lever 78 is provided at one end of the rotation shaft 76. The rotation shaft 76 is rotatably attached to the device main body 12. Then, when the drive lever 78 is rotated around the rotation shaft 76 by a drive means (not shown) provided in the apparatus main body 12, the rotation shaft 76 also rotates. As a result, the medium return lever 64 also rotates around the rotation shaft 76 in accordance with the rotation of the rotation shaft 76.

As shown in FIG. 6, the medium return lever 64 protrudes from the medium support portion 32 into the medium transport path 80 for transporting the medium P and retracts from the medium transport path 80 in response to the rotation of the rotation shaft 76. The posture (not shown) can be switched. Here, referring to FIGS. 2 and 14, when the medium P is sent downstream from the medium supporting portion 32 in the feeding direction, the medium supporting portion 32 is switched from the second state to the first state, and the feeding roller 34 It swings in the direction in contact with. Then, the feeding roller 34 comes into contact with the uppermost medium P placed on the medium supporting portion 32, and feeds the highestmost medium P to the downstream side of the feeding path. At this time, the next and subsequent media P are separated from the uppermost medium P by the separation roller 36, and the medium return lever 64 projects into the medium transport path 80, so that the separated next and subsequent media P is the medium. It is returned to the support portion 32 to prevent the next and subsequent media from being inadvertently fed to the downstream side of the medium transport path 80. The medium transport path 80 is a medium transport path from the medium support portion 32 to the recording head 26 via the feed roller 34, the separation roller 36, and the transport roller pair 46.

Hereinafter, with reference to FIGS. 15 to 18, the path through which the medium passes when recording is performed on both sides of the medium fed from the rear feeding unit 28 will be further described.
When recording is performed on both sides of the medium, the medium fed from the medium support unit 32 constituting the rear feeding unit 28 is recorded by the recording head 26 and then recorded by the transfer roller pair 46. Is conveyed in the direction opposite to the conveying direction (direction of arrow f1 in FIG. 15) and enters the medium reversing unit 30. In FIG. 15, reference numeral S1 indicates an example of a medium directed to the reversing roller 38 (curved path around the reversing roller 38) of the medium reversing unit 30.
Reference numeral 90 is a path forming member forming the lower side of the transport path of the medium from the transport roller pair 46 to the reversing roller 38.

Then, the medium is curved and inverted by the reversing roller 38, and as shown in FIG. 16, the medium moves downstream from the nip position of the reversing roller 38 and the driven roller 40. In FIG. 16, reference numeral S2 indicates an example of a medium whose tip passes through the nip position of the reversing roller 38 and the driven roller 40 and heads toward the downstream side.
Reference numeral 41 is a driven roller provided on the upstream side of the driven roller 40, which is not shown in FIGS. 2, 6, and 14. Like the upstream roller 42, the driven roller 41 is housed in the occupied area of the reversing roller 38 in the device depth direction (Y direction), and the dimension of the device in the depth direction is suppressed.

As is clear from the contents shown in FIGS. 15 and 16, the medium inverted by the medium inversion unit 30 is a part of the back surface of the back feed unit 28, more specifically, a part of the back surface of the support frame 62. It is fed to the transport roller pair 46 through the transport path formed by the path forming portion 62a.
That is, in other words, the back feed unit 28 itself forms a transport path for the medium that is inverted by the medium reversing unit 30 and sent to the transport roller pair 46, so that the back feed unit 28 and the medium reversing unit 30 are combined. In the configuration provided, it is possible to reduce the number of parts and suppress the increase in size of the device.

The medium transported in the f1 direction) enters the medium reversing unit 30 through the lower side of the roller support member 68, and is again fed to the transport roller pair 46 through the lower side of the roller support member 68.
That is, in other words, the back feed unit 28 itself forms a transport path for the medium from the transport roller pair 46 to the medium reversing unit 30, and is inverted by the medium reversing unit 30 and fed to the transport roller pair 46. Since the medium transport path is formed, it is possible to suppress the reduction in the number of parts and the increase in size of the device in the configuration including the rear feed unit 28 and the medium reversal unit 30.

The gap between the roller support member 68 and the path forming member 90 (reference numeral 92 in FIG. 17) is the rotation of the feeding roller 34 (that is, the feeding of the medium from the rear feeding unit 38) as shown in FIG. ) Narrows down. That is, the roller support member 68 can swing around the swing shaft 68b, and the separation roller 36 is urged in the direction toward the feeding roller 34 by the urging means 72 (FIG. 2). When not feeding, as shown in FIG. 15, the flat portion of the feeding roller 34 faces the separating roller 36, whereby the roller supporting member 68 is in the raised position, and the roller supporting member 68 and the path forming member 90 The gap (width of the transport path) formed between and is widened.

When the feeding roller 34 rotates from this state and the feeding of the medium is started, the arc portion of the feeding roller 34 pushes down the separation roller 36, the roller support member 68 takes a lowering position, and the roller The gap (width of the transport path) formed between the support member 68 and the path forming member 90 is narrowed. In this state, since the medium is being fed from the rear feeding unit 28, the medium is not transported from the transport roller pair 46 to the medium reversing unit 30.

As shown in FIG. 18, the medium is located at the nip position between the reversing roller 38 and the driven roller 40, that is, at the outlet of the curved path around the reversing roller 38 and the lower side of the roller support member 68. A space Ar capable of forming the deflection of the space Ar is provided. This space Ar is used when skewing the medium. That is, when skew correction is performed on the medium (reference numeral S3 in FIG. 18) transported from the reversing roller 38 toward the transport roller pair 46, the tip of the medium is rotated by the reversing roller 38 with respect to the transport roller pair 46 whose rotation has been stopped. Hit by rotation.
At this time, by forming a deflection in the medium between the transport roller pair 46 and the reversing roller 38, the tip of the medium is made to imitate the nip of the transport roller pair 46. Since the space Ar is provided in the medium transport path between the outlet of the curved path in the medium reversing unit 30 and the lower side of the roller support member 68, skew is performed on the upstream side of the transport roller pair 46. ) The deflection for correction can be formed appropriately, and the skew correction can be appropriately performed.

Attempt, the roller 84 comes into contact with the uppermost medium P in the plurality of media P.

Then, when the feeding is started in the plurality of media P supported by the medium supporting portion 32 and the auxiliary tray 44, the feeding is performed from the highest-level medium P to the downstream side in the feeding direction. Here, when the uppermost medium P is nipped into the feeding roller 34 and the separating roller 36 and pulled into the apparatus main body 12, the roller 84 rotates according to the movement of the uppermost medium P. As a result, the transport load at the time of feeding the top-level medium P is reduced, and it is possible to reduce the damage to the top-level medium P when the top-level medium P is fed.

Further, referring to FIG. 11, when the air supply port cover 18 is closed with respect to the device main body 12, the roller 84 is housed in the device main body 12. Here, for example, if the feed port cover 18 is not provided with the roller 84, the feed port cover 18 comes into contact with the medium P supported by the medium support portion 32 and the auxiliary tray 44, and the transport load becomes large. The medium P may be scratched when it is fed. Therefore, if the auxiliary tray 44 is provided with a rib for supporting the feed port cover 18 so that the feed port cover 18 does not come into contact with the medium P supported by the medium support portion 32, the auxiliary tray 44 is provided in the apparatus main body 12. The storage space of the auxiliary tray 44 increases according to the height dimension of the rib. As a result, the size of the printer 10 becomes large. In this embodiment, since the roller 84 is provided on the air supply port cover 18, the storage space of the auxiliary tray 44 can be reduced, and the device size can be reduced.

Further, when the auxiliary tray 44 is switched from the used state to the stored state, the auxiliary tray 44 is also completely stored in the apparatus main body 12. As a result, as shown in FIG. 11, the upper surface and the back surface of the printer 10 are in a flat state, and the design is excellent.
