As a restricting portion, a first protrusion portion 36 is provided on the bottom surface of the first storage portion 34 so as to protrude upward and extend along the paper feeding direction (arrow A direction) (FIGS. 5 and 6). a) and FIG. 8 (a)). The first protrusions 36 also function as reinforcing ribs in the auxiliary support member 33, and can increase the rigidity of the auxiliary support member 33. Two (a pair) of first protrusions 36 are provided side by side in the width direction on the downstream side of the sheet feeding direction (arrow A direction) on the bottom surface of the first storage portion 34. The number of the first protrusions 36 is not limited to this number, but it is desirable that the number of the first protrusions 36 be plural in order to restrict the bending of the paper P and stably support it.

  The discharge auxiliary tray 35 is provided with a long hole 37 into which the first protrusion 36 can be loosely fitted at the storage position, and the discharge auxiliary tray 35 is stored in the first storage portion 34. Sometimes, the upper end of the first protrusion 36 slightly protrudes from the elongated hole 37 (see FIGS. 6B and 7B). In other words, the discharge assist tray 35 is folded. In this state, it is arranged within the height of the first protrusion 36, so that the occupied space in the height direction can be made compact. By providing the bottom side of the first storage portion 34 on the downstream side in the paper feeding direction (in the direction of arrow A), the long hole 37 formed in the paper discharge auxiliary tray 35 can be separated from the pivot 38 serving as a pivot point of rotation. The rigidity of the discharge auxiliary tray 35 is prevented from being lowered.

  The auxiliary support member 33 has a rectangular shape in plan view, and the bottom plate 31 can slidably hold both side portions along the paper feeding direction (arrow A direction) of the auxiliary support member 33 and can accommodate the auxiliary support member 33. The 2nd accommodating part 39 is formed (refer FIG.5, FIG.6 (a) and FIG.8 (a)). The auxiliary support member 33 is attached to the second storage portion 39 by forming the upper surface of the auxiliary support member 33 on a flat surface that is flush with the both side portions, and the both side portions are provided on the inner side surface of the second storage portion 39 as they are. The structure is fitted in the slide groove 40, and the cost is reduced by a simple shape. Therefore, in this embodiment, the upper surface of the auxiliary support member 33 is slightly lower than the upper surface of the bottom plate 31.

  And the 2nd protrusion 41 which protrudes upwards and extends along a feed direction is provided in the outer side of the width direction rather than the area | region of the 1st accommodating part 34 in this auxiliary | assistant support member 33. As shown in FIG. The height of the upper surface of the second ridge 41 is substantially flush with the height of the upper surface of the first ridge 36 and the height of the upper surface of the bottom plate 31 of the sheet feeding cassette 3. Strictly speaking, as shown in FIGS. 6A and 7A, the auxiliary support member 33 slides slightly with respect to the bottom plate 31 in the paper feeding direction (arrow A direction). Since the slide groove 40 is provided, the upper surface of the first protrusion 36 and the upper surface of the second protrusion 41 on the downstream side in the paper feeding direction (arrow A direction) when the auxiliary support member 33 is pulled out. Is substantially flush with the upper surface of the bottom plate 31 (see FIG. 7A), and in a state where the auxiliary support member 33 is housed in the second housing portion 39, the feeding direction of the second protrusion 41 (arrow) (A direction) It is comprised so that the upper surface of an upstream side may become substantially flush with the upper surface of the baseplate 31 (refer FIG.7 (b)). Accordingly, even when the auxiliary support member 33 is stored in the second storage portion 39, the paper P on the bottom plate 31 is supported by the second protrusion 41 without being bent toward the upper surface side of the auxiliary support member 33. ing.

  The second protrusion 41 is longer in the paper feeding direction (arrow A direction) than the first protrusion 36, and in this embodiment, two (a pair) are provided with the first protrusion 36 in between. However, the number of the second protrusions 41 is not limited to this.

  In addition, at least each downstream end of the first protrusion 36 and the second protrusion 41 in the sheet feeding direction (arrow A direction) is located inside the notch 43 of the sheet discharge tray 10b in plan view. The taper has a height that gradually decreases toward the downstream side, that is, a so-called chamfered shape. That is, the taper-shaped part 36a is provided in the 1st protrusion part 36, and the taper-shaped part 41a is each provided in the 2nd protrusion part 41 (refer FIG.5, FIG.6 (a) and FIG.7 (a)). For example, when the paper P is a relatively small size such as a postcard size, even if the downstream end in the paper discharge direction (arrow B direction) falls downward from the notch 43, the paper P The first protrusion 36 and the second protrusion 41 are designed so as not to get caught in the downstream corner of the sheet feeding direction (arrow A direction).

  According to the above configuration, when the sheet P having a long length in the sheet feeding direction (arrow A direction) such as the legal size is accumulated and accommodated in the sheet feeding cassette 3, the user opens the grip opening of the sheet feeding cassette 3. 42, the auxiliary support member 33 is pulled out from the second storage portion 39 of the bottom plate 31, and a finger is put on the turning notch portion 46 of the auxiliary support member 33, so that the discharge auxiliary tray 35 is removed from the first storage portion 34. The rotation is released, and the discharge assist tray 35 is moved to the extended position where it is inclined (see FIGS. 5, 6A and 7A).

  Based on the image recording command, the sheets P placed on the bottom plate 31 of the sheet feeding cassette 3 are separated one by one in the sheet feeding direction (arrow A direction), and a substantially U-shaped path is passed. It is conveyed to the recording unit 7 through the feeding path 9 that includes it. Then, the paper P that has passed through the recording unit 7 is discharged from the paper discharge unit 10 along the paper discharge direction (arrow B direction) and is deposited on the paper discharge tray 10b.

  Since the length of the paper P is long, when the rear end (upstream end of the paper discharge direction) of the paper P is released from contact with the paper discharge roller 28, the front end (downstream of the paper discharge direction). The end portion is conveyed to a position protruding from the paper discharge tray 10b. At this time, the paper discharge auxiliary tray 35 has the paper feed cassette 3 positioned below the paper discharge tray 10b as the base end side, and the front end side protrudes upward to substantially the same height as the paper discharge tray 10b. The front end of the paper P protruding from the paper discharge tray 10b is received by the paper discharge auxiliary tray 35 without hanging down (see FIG. 1). Thus, the paper P discharged from the paper discharge unit 10 is supported across the paper discharge tray 10b and the paper discharge auxiliary tray 35, and the discharged paper P is sequentially and stably stacked and deposited. There is no fear of dropping the tray 10b causing the inconvenience that the order of deposition is disturbed.

  On the other hand, in the first storage section 34 of the paper feed cassette 3, since the discharge auxiliary tray 35 is in the extended position, the concave surface is exposed on the bottom plate 31, and the upper surface of the auxiliary support member 33 is lower than the bottom plate 31. Yes. However, since the first protrusion 36 and the second protrusion 41 are provided so as to be substantially flush with the bottom plate 31, the paper P is supported as shown in FIG. It is possible to prevent the sheet P from falling and bending inside the first storage portion 34 or the upper surface of the auxiliary support member 33.

  Temporarily, when the 1st protrusion part 36 and the 2nd protrusion part 41 are not provided, as shown in FIG.8 (b), the paper P is the inside of the 1st accommodating part 34, or the auxiliary | assistant support member 33. It falls on the top surface and bends. As a result, the paper P stored in the paper feed cassette 3 for a long time has a bending wrinkle, so that the paper feeding means 6 double feeds the paper P or causes paper jam or paper jam (paper jam) during the transportation. There are concerns about the occurrence. Further, when the sheet is conveyed to the recording unit 7 with a bending wrinkle, the distance between the upper surface of the paper P and the recording head 4 is partially different, particularly when the recording head 4 is an ink jet type as in this embodiment. This will have a large adverse effect on the recording quality.

  Further, when the paper cassette 3 stores, for example, A4 size, letter size, postcard size paper P, etc., the paper discharge auxiliary tray 35 is stored in the first storage portion 34, and the auxiliary support member 33 is the first support member 33. 2 is stored in the storage unit 39. If necessary, the auxiliary support member 33 is stored in the second storage portion 39 while the discharge auxiliary tray 35 is in the extended position, or the auxiliary support member 33 is set while the discharge auxiliary tray 35 is in the storage position. May be pulled out, and these can be set in combination as appropriate.

  In the embodiment described above, the discharge auxiliary tray 35 is provided on the auxiliary support member 33 of the paper feed cassette 3. However, as shown in FIG. 9, the auxiliary support member 33 is provided on the paper feed cassette 3. If not, the auxiliary discharge tray 35 may be directly attached to the bottom plate 31 of the paper feed cassette 3. In FIG. 9, the same reference numerals are given to the same components as those of the paper feed cassette 3 of the above embodiment.

  Further, in the above embodiment, the discharge auxiliary tray 35 is moved by rotation, but may be configured to slide. In that case, an elongated cutout is formed instead of the elongated hole 37.

  In addition, the present invention is not only applied to a configuration in which the paper feed cassette described above is only one stage, but also in an image recording apparatus having a plurality of paper feed cassettes on the upper and lower sides, the uppermost stage closest to the paper discharge unit. You may apply to a paper feed cassette.
