About.

  A recording apparatus such as a so-called ink jet printer is provided with an automatic feeding apparatus for feeding a recording medium such as plain paper or photographic paper to a recording means. However, a recording medium such as board paper or cardboard (hereinafter referred to as “thick paper”) or a tray on which an optical disk is set has high rigidity and cannot be bent. It is often difficult to feed to the means.

  As an example of the prior art capable of solving such problems, a highly rigid recording medium is inserted substantially horizontally through a guide (hereinafter referred to as “manual feeding guide”) provided on the front side of the apparatus. In addition, a recording apparatus including a manual feeding unit that enables feeding to the recording unit is known (see, for example, Patent Document 1 or 2).

  According to the recording apparatus including such a manual feeding unit, it is possible to perform recording on a recording medium such as cardboard which is difficult to be fed by the automatic feeding apparatus. It is also possible to perform recording on the label surface of the optical disk mounted on the disk tray.

It is supposed to be done. Thereby, it is possible to prevent the leading end of the recording medium from entering and being caught between the auxiliary guide 11 and the second discharge driving roller 29. Note that the arrangement position of the guide piece 38 in the medium width direction coincides with the guide piece 37 in the present embodiment.

  Furthermore, in this embodiment, guide rollers 35 and 36 are provided at the upstream end and the downstream end of the guide surface 11a in the auxiliary guide 11 (FIG. 2). Thereby, the feeding load when feeding the recording medium manually is reduced.

  In the embodiment described above, a portion that overlaps in the manual feeding direction is provided between the manual feeding guide 10 and the auxiliary guide 11, and the manual feeding path (more specifically, the manual feeding path). The continuity of the guide member) is ensured. However, the present invention is not limited to this configuration, and the continuity of the manual feed path (guide member that supports the paper) between the manual feed guide 10 and the second medium discharge means 28 (second discharge drive roller 29). Can be prevented from being caught between the manual feed guide 10 and the second medium discharge means 28 (second discharge drive roller 29).

  For example, the guide member that forms the support surface of the recording medium between the manual feed guide 10 and the second medium discharge means 28 (second discharge drive roller 29) is not limited to the auxiliary guide 11 alone, and includes a plurality of guide members. It may be a member. Further, the support surface of the recording medium is not interrupted at all between the manual feed guide 10 and the second medium discharge means 28 (second discharge drive roller 29), and may be configured to be continuous.
