The operation unit 5 is provided with hard keys such as a start key in addition to the touch panel 51. The operation unit 5 is rotatably supported by an exterior member of the image forming apparatus 100. For example, the operation unit 5 includes a first posture (see FIGS. 1 to 3) in which the surface of the operation unit 5 (the surface of the touch panel 51) is parallel to the vertical plane and a second posture in which the touch panel 51 is parallel to the horizontal plane. It can be rotated between.
　シート排出装置６は、鉛直方向に並設された複数のシート排出トレイ７を備える。シート排出装置６は、画像形成装置１００の画像形成部３による画像形成後のシートを複数のシート排出トレイ７のうち予め設定されるシート排出トレイ７に排出することが可能である。例えば、画像形成装置１００のユーザーごと又はユーザーの部署ごとに使用されるシート排出トレイ７が予め設定されていることが考えられる。 The sheet discharge device 6 includes a plurality of sheet discharge trays 7 arranged in parallel in the vertical direction. The sheet discharge device 6 can discharge a sheet after image formation by the image forming unit 3 of the image forming apparatus 100 to a preset sheet discharge tray 7 among the plurality of sheet discharge trays 7. For example, it is conceivable that the sheet discharge tray 7 used for each user of the image forming apparatus 100 or for each user department is set in advance.
　そして、シート排出装置６は、画像形成装置１００の制御部（不図示）からの制御指示に従ってシートを複数のシート排出トレイ７のいずれかに排出する。このときのシートのシート排出トレイ７への排出方向（図１～図３における左方向）をシート排出方向Ｄ１４と称する。 Then, the sheet discharge device 6 discharges the sheet to one of the plurality of sheet discharge trays 7 in accordance with a control instruction from a control unit (not shown) of the image forming apparatus 100. The discharge direction of the sheet to the sheet discharge tray 7 at this time (left direction in FIGS. 1 to 3) is referred to as a sheet discharge direction D14.
　シート排出トレイ７は、図２及び図３に示されるように、シート排出装置６により回動可能に支持されている。これにより、ユーザーは、シート排出トレイ７からシートを取り出す際に、そのシート排出トレイ７の上方に一又は複数のシート排出トレイ７が存在する場合に、その一又は複数のシート排出トレイ７を回動させて間隔を広げることが可能である。 The sheet discharge tray 7 is rotatably supported by a sheet discharge device 6 as shown in FIGS. As a result, when the user takes out the sheet from the sheet discharge tray 7, if one or more sheet discharge trays 7 exist above the sheet discharge tray 7, the user rotates the one or more sheet discharge trays 7. It can be moved to widen the interval.
［シート排出トレイ７］
　次に、図４～図７を参照しつつ、シート排出トレイ７について詳細に説明する。ここに、図４及び図５は、シート排出トレイ７の斜視図である。また、図６は、図４におけるＶＩ－ＶＩ断面図であり、図７は、図４におけるＶＩＩ－ＶＩＩ断面図である。図４にはシート排出トレイ７の上面側が表れており、図５にはシート排出トレイ７の下面側が表れている。図４～図７に示されているように、シート排出トレイ７は、載置部７１、回動支持部７２、上壁部７３、下壁部７４、及びリブ７５を備える。 [Sheet discharge tray 7]
Next, the sheet discharge tray 7 will be described in detail with reference to FIGS. 4 and 5 are perspective views of the sheet discharge tray 7. 6 is a sectional view taken along line VI-VI in FIG. 4, and FIG. 7 is a sectional view taken along line VII-VII in FIG. 4 shows the upper surface side of the sheet discharge tray 7, and FIG. 5 shows the lower surface side of the sheet discharge tray 7. As shown in FIGS. 4 to 7, the sheet discharge tray 7 includes a placement portion 71, a rotation support portion 72, an upper wall portion 73, a lower wall portion 74, and a rib 75.
　載置部７１は、表面７１Ａ及び裏面７１Ｂを有する。載置部７１の表面７１Ａには、画像形成部３による画像形成後、予め定められたシート排出方向Ｄ１４に沿って排出されるシートが載置される。また、載置部７１は、シート排出方向Ｄ１４に沿って第１領域７６Ａ及び第２領域７６Ｂを有する。第１領域７６Ａは、載置部７１のシート排出方向Ｄ１４における上流側の領域である。第２領域７６Ｂは、載置部７１のるシート排出方向Ｄ１４における第１領域７６Ａの下流側の領域であって、第１領域７６Ａよりも上壁部７３からの長さが短い。即ち、載置部７１では、シート排出方向Ｄ１４における下流側の一部が上流側に比べて上壁部７３側（画像形成装置１００の後方側）に退避している。 The mounting portion 71 has a front surface 71A and a back surface 71B. A sheet discharged along the predetermined sheet discharge direction D <b> 14 after the image formation by the image forming unit 3 is placed on the surface 71 </ b> A of the placement unit 71. The placement unit 71 includes a first region 76A and a second region 76B along the sheet discharge direction D14. The first area 76 </ b> A is an upstream area of the placing portion 71 in the sheet discharge direction D <b> 14. The second region 76B is a region on the downstream side of the first region 76A in the sheet discharge direction D14 of the placement unit 71, and the length from the upper wall portion 73 is shorter than the first region 76A. That is, in the loading unit 71, a part of the downstream side in the sheet discharge direction D14 is retracted to the upper wall 73 side (the rear side of the image forming apparatus 100) compared to the upstream side.
　例えば、第１領域７６Ａのシート排出方向Ｄ１４に垂直な幅方向Ｄ１５の長さは、画像形成装置１００における予め定められた最大印刷可能サイズのシートが排出される際のそのシートの幅方向Ｄ１５の長さに対応する。また、第１領域７６Ａのシート排出方向Ｄ１４の長さは、前記最大印刷可能サイズのシートが排出される際のそのシートのシート排出方向Ｄ１４の長さよりも短い。一方、第２領域７６Ｂのシート排出方向Ｄ１４に垂直な幅方向Ｄ１５の長さは、前記最大印刷可能サイズのシートが排出される際のそのシートの幅方向Ｄ１５の長さよりも短い。 For example, the length in the width direction D15 perpendicular to the sheet discharge direction D14 of the first region 76A is set in the width direction D15 of the sheet when the predetermined maximum printable size sheet is discharged in the image forming apparatus 100. Corresponds to the length. The length of the first region 76A in the sheet discharge direction D14 is shorter than the length of the sheet in the sheet discharge direction D14 when the maximum printable size sheet is discharged. On the other hand, the length in the width direction D15 perpendicular to the sheet discharge direction D14 of the second region 76B is shorter than the length in the width direction D15 of the sheet when the maximum printable size sheet is discharged.
　そのため、少なくとも前記最大印刷可能サイズのシートが、第１領域７６Ａ及び第２領域７６Ｂによって支持される際、前記シートにおける画像形成装置１００の前面側の一部が支持部７１に支持されていない浮遊状態となる。従って、ユーザーは、シート排出トレイ７に載置されたシートの浮遊箇所を画像形成装置１００の前面側から掴んで容易に取り出すことが可能である。なお、第１領域７６Ａ及び第２領域７６Ｂのサイズは、ここで説明したものに限らず、画像形成装置１００から排出されるシートサイズのうち予め定められた一又は複数の所定サイズのシートの取り出しが容易となるように予め定められていればよい。 Therefore, when at least the maximum printable size sheet is supported by the first region 76A and the second region 76B, a part of the sheet on the front side of the image forming apparatus 100 is not supported by the support unit 71. It becomes a state. Therefore, the user can easily take out the floating portion of the sheet placed on the sheet discharge tray 7 from the front side of the image forming apparatus 100. Note that the sizes of the first area 76A and the second area 76B are not limited to those described here, and one or a plurality of predetermined-size sheets that are predetermined from among the sheet sizes discharged from the image forming apparatus 100 are taken out. It suffices if it is determined in advance so as to be easy.
　回動支持部７２は、シート排出トレイ７のシート排出方向Ｄ１４の上流側端部において、シート排出方向Ｄ１４に垂直な幅方向Ｄ１５の両端部に設けられている。そして、シート排出トレイ７は、回動支持部７２がシート排出装置６で回動可能に軸支されることにより、回動支持部７２を軸に回動可能である。なお、回動支持部７２は、シート排出装置６の筐体内で軸支されており、図１～図３に示されているように外部には露出していない。 The rotation support portions 72 are provided at both ends of the sheet discharge tray 7 at the upstream end in the sheet discharge direction D14 and in the width direction D15 perpendicular to the sheet discharge direction D14. The sheet discharge tray 7 is rotatable about the rotation support portion 72 as the rotation support portion 72 is pivotally supported by the sheet discharge device 6. The rotation support portion 72 is pivotally supported in the housing of the sheet discharge device 6 and is not exposed to the outside as shown in FIGS.
　上壁部７３は、載置部７１におけるシート排出方向Ｄ１４に垂直な幅方向Ｄ１５の一方の端部に設けられ、載置部７１の表面７１Ａから上方に向けて突出している。より具体的に、上壁部７３は、シート排出装置６が画像形成装置１００に装着された状態で、画像形成装置１００の予め定められた後方側の端部に位置する。なお、画像形成装置１００の前後方向Ｄ１３において、ユーザーによって操作される操作部５が設けられている側が画像形成装置１００の前方側である。 The upper wall portion 73 is provided at one end portion in the width direction D15 perpendicular to the sheet discharge direction D14 in the placement portion 71, and protrudes upward from the surface 71A of the placement portion 71. More specifically, the upper wall portion 73 is located at a predetermined rear end of the image forming apparatus 100 in a state where the sheet discharge device 6 is mounted on the image forming apparatus 100. In the front-rear direction D13 of the image forming apparatus 100, the side on which the operation unit 5 operated by the user is provided is the front side of the image forming apparatus 100.
　一方、シート排出トレイ７の幅方向Ｄ１５における上壁部７３とは反対側の端部には、載置部７１の表面７１Ａから上方に向けて突出する壁部が設けられていない。即ち、シート排出装置６が画像形成装置１００に装着された状態で、シート排出トレイ７の載置部７１の表面７１Ａは、画像形成装置１００の前方側が開放された状態である。 On the other hand, the end of the sheet discharge tray 7 opposite to the upper wall 73 in the width direction D15 is not provided with a wall that protrudes upward from the surface 71A of the mounting portion 71. That is, with the sheet discharge device 6 mounted on the image forming apparatus 100, the front surface 71 </ b> A of the placement portion 71 of the sheet discharge tray 7 is in a state where the front side of the image forming apparatus 100 is open.
　このように、シート排出トレイ７の載置部７１の表面７１Ａでは、画像形成装置１００の前方側に上方に突出する壁部が設けられていない。そのため、ユーザーは、シート排出トレイ７に載置されているシートを画像形成装置１００の前方側から容易に取り出すことが可能である。より具体的に、ユーザーは、シート排出トレイ７の載置部７１に載置されたシートを前方に滑らせて取り出すことが可能である。 Thus, on the front surface 71A of the placement portion 71 of the sheet discharge tray 7, a wall portion protruding upward is not provided on the front side of the image forming apparatus 100. Therefore, the user can easily take out the sheet placed on the sheet discharge tray 7 from the front side of the image forming apparatus 100. More specifically, the user can slide the sheet placed on the placement unit 71 of the sheet discharge tray 7 forward and take it out.
　なお、シート排出トレイ７の載置部７１の表面７１Ａにおいて、仮に上壁部７３も省略される構成では、ユーザーがシートを取り出す際に、前記シートが後方側に移動することがあり、前記シートが取り出しづらくなるおそれがある。しかしながら、本実施形態に係るシート排出トレイ７では、画像形成装置１００の後方側の端部には上壁部７３が設けられている。そのため、ユーザーがシートを取り出す際、前記シートの後方側への移動が上壁部７３によって制限されるため、ユーザーによるシートの取り出し作業が容易である。 In the configuration in which the upper wall portion 73 is also omitted on the surface 71A of the placement portion 71 of the sheet discharge tray 7, the sheet may move rearward when the user takes out the sheet. May be difficult to remove. However, in the sheet discharge tray 7 according to the present embodiment, an upper wall portion 73 is provided at the rear end portion of the image forming apparatus 100. For this reason, when the user takes out the sheet, the movement of the sheet to the rear side is restricted by the upper wall portion 73, so that the user can easily take out the sheet.
　下壁部７４は、シート排出トレイ７の幅方向Ｄ１５における上壁部７３とは反対側の端部に設けられ、載置部７１から下方に向けて突出している。より具体的に、下壁部７４は、シート排出装置６が画像形成装置１００に装着された状態で、画像形成装置１００の前方側に位置する。これにより、シート排出トレイ７の幅方向Ｄ１５における上壁部７３とは反対側の端部が下壁部７４によって補強される。 The lower wall portion 74 is provided at an end of the sheet discharge tray 7 opposite to the upper wall portion 73 in the width direction D15 and protrudes downward from the placement portion 71. More specifically, the lower wall portion 74 is located on the front side of the image forming apparatus 100 in a state where the sheet discharge device 6 is mounted on the image forming apparatus 100. As a result, the end of the sheet discharge tray 7 opposite to the upper wall 73 in the width direction D15 is reinforced by the lower wall 74.
　また、シート排出トレイ７では、上壁部７３が載置部７１の裏面７１Ｂから下方にも突出しており、シート排出方向Ｄ１４の下流側端部にも載置部７１から下方に突出する下壁部７４Ａ（図５及び図６参照）が設けられている。このように、シート排出トレイ７の載置部７１の裏面７１Ｂには、上壁部７３、下壁部７４、及び下壁部７４Ａによって、幅方向Ｄ１５の両端部とシート排出方向Ｄ１４の下流側端部とに亘って連続する下壁部が形成されており、シート排出トレイ７が補強されている。 In the sheet discharge tray 7, the upper wall portion 73 protrudes downward from the back surface 71 </ b> B of the placement portion 71, and the lower wall protrudes downward from the placement portion 71 to the downstream end portion in the sheet discharge direction D <b> 14. A portion 74A (see FIGS. 5 and 6) is provided. As described above, the upper surface 73, the lower wall 74, and the lower wall 74A are provided on the back surface 71B of the placement portion 71 of the sheet discharge tray 7 so that both ends in the width direction D15 and the downstream side in the sheet discharge direction D14. A lower wall portion continuous to the end portion is formed, and the sheet discharge tray 7 is reinforced.
　さらに、シート排出トレイ７では、シート排出トレイ７のシート搬送方向Ｄ１４における上流側端部において、載置部７１の裏面７１Ｂ側に、幅方向Ｄ１５の両端部の上壁部７３及び下壁部７４を接続する下壁部７４Ａ（図５参照）が設けられている。即ち、シート排出トレイ７には、シート排出トレイ７の全周に亘って載置部７１の裏面７１Ｂから下方に突出する上壁部７３、下壁部７４、下壁部７４Ａ、及び下壁部７４Ｂ各々を含み、シート排出トレイ７を補強する補強部が設けられている。 Further, in the sheet discharge tray 7, the upper wall portion 73 and the lower wall portion 74 of both end portions in the width direction D15 are disposed on the back surface 71 </ b> B side of the placement portion 71 at the upstream end portion in the sheet conveyance direction D <b> 14 of the sheet discharge tray 7. A lower wall portion 74A (see FIG. 5) is provided. That is, the sheet discharge tray 7 includes an upper wall portion 73, a lower wall portion 74, a lower wall portion 74 </ b> A, and a lower wall portion that protrude downward from the back surface 71 </ b> B of the placement portion 71 over the entire circumference of the sheet discharge tray 7. Reinforcing portions for reinforcing the sheet discharge tray 7 are provided including each of 74B.
　リブ７５は、図５及び図６に示されているように、載置部７１の裏面７１Ｂにおいて幅方向Ｄ１５に所定間隔で複数並設されている。リブ７５は、載置部７１の裏面７１Ｂから下方に突出して設けられており、シート排出方向Ｄ１４に長尺状である。具体的に、リブ７５は、図５及び図７に示されているように、シート排出方向Ｄ１４に沿って下壁部７４Ａ及び下壁部７４Ｂに接続されている。これにより、シート排出トレイ７は、複数のリブ７５によっても補強されている。 As shown in FIGS. 5 and 6, a plurality of ribs 75 are arranged in parallel in the width direction D <b> 15 on the back surface 71 </ b> B of the placement portion 71. The ribs 75 are provided so as to protrude downward from the back surface 71B of the placement portion 71, and are long in the sheet discharge direction D14. Specifically, as shown in FIGS. 5 and 7, the rib 75 is connected to the lower wall portion 74 </ b> A and the lower wall portion 74 </ b> B along the sheet discharge direction D <b> 14. Thereby, the sheet discharge tray 7 is also reinforced by the plurality of ribs 75.
　また、シート排出装置６では、下方に配置されたシート排出トレイ７にシート排出方向Ｄ１４に沿って排出されるシートがその上方に配置されたシート排出トレイ７の下壁部７４Ａに接触し、前記シートの正常な搬送が阻害されるおそれがある。これに対し、シート搬送装置６では、図５及び図７に示されているように、リブ７５の下端位置がシート搬送方向Ｄ１４の下流端部の下壁部７４Ａの下端位置と同じである。即ち、下壁部７４の下端が、リブ７５の下端から下方に突出していない。これにより、下方に配置されたシート排出トレイ７に排出されるシートは、その上方に配置されたシート排出トレイ７のリブ７５によって下壁部７４Ａへの接触が抑制される。なお、リブ７５の下端位置は、下壁部７４Ａの下端位置と同じ場合に限らず、下壁部７４Ａの下端位置よりも下方に位置していてもよい。 Further, in the sheet discharge device 6, the sheet discharged along the sheet discharge direction D14 to the sheet discharge tray 7 disposed below contacts the lower wall portion 74A of the sheet discharge tray 7 disposed above the sheet discharge tray 7, The normal conveyance of the sheet may be hindered. On the other hand, in the sheet conveying apparatus 6, as shown in FIGS. 5 and 7, the lower end position of the rib 75 is the same as the lower end position of the lower wall portion 74A of the downstream end portion in the sheet conveying direction D14. That is, the lower end of the lower wall portion 74 does not protrude downward from the lower end of the rib 75. Thereby, the sheet discharged to the sheet discharge tray 7 disposed below is prevented from contacting the lower wall portion 74A by the ribs 75 of the sheet discharge tray 7 disposed above. The lower end position of the rib 75 is not limited to the same as the lower end position of the lower wall portion 74A, and may be located below the lower end position of the lower wall portion 74A.
