Because construct disk body 54 and extension dish 59 in this mode, so extension dish 59 can slide along first direction 36 and second direction 37 with respect to disk body 54.When extension dish 59 is contained in state (referring to Fig. 9 and Figure 10) the disk body 54 when second direction 37 is pulled out from it, the paper placement surface of sheet feed stacker 29 is extended.On the contrary, when extension dish 59 from its state (for example, Fig. 6 to Fig. 8) that is drawn out disk body 54 with respect to disk body 54 when first direction 36 pushes, the paper placement surface withdrawal of sheet feed stacker 29.

Figure 11 is the schematic perspective view that demonstrates the face side of paper disc 21, and shows the state that extension dish 61 is pulled out along second direction 37 with respect to disk body 56.Figure 12 is the schematic perspective view that is presented at the back side of paper discharge tray 21 under the state shown in Figure 11.Figure 13 is the schematic perspective view that demonstrates the face side of paper disc 21, and shows the state that extension dish 61 pushes along first direction 36 with respect to disk body 56.Figure 14 is the schematic perspective view that is presented at the back side of paper discharge tray 21 under the state shown in 13.Figure 11～14 demonstrate the state of paper disc 21 from sheet feed stacker 29 dismountings.

The width setup of disk body 56 and extension dish 61 is to be shorter than two distances between the side guide plate 78.Owing to this reason, when disk body 56 was supported by disk body 54, paper discharge tray 21 was arranged on the inboard of sheet feed stacker 29 on its Width.

From planimetric map, disk body 56 is spill (referring to Figure 12 and Figure 14) basically.Shown in Figure 11～14, rotating shaft 35 is arranged on the disk body 56.Rotating shaft 35 is separately positioned on the two ends of the front end 84 of disk body 56 on its Width (horizontal direction 74 among Fig. 6).When rotating shaft 35 was inserted in the support holes 66 (referring to Fig. 7 etc.) respectively, axially going up that supported paper discharge tray 21 can extend around the Width along sheet feed stacker 29 rotated.

Figure 15 is the enlarged drawing of the part XV among Figure 11.Figure 16 is the enlarged drawing of the part XVI among Figure 11.

As Figure 15 and shown in Figure 16, the end face of disk body 56 has the guide groove 115 that xsect is the U font.Formed guide groove 115 makes the surface of disk body 56 can be recessed towards its back side.Guide groove 115 is arranged on the whole zone of disk body 56 and along first direction 36 and second direction 37 and extends.When the lug 58 (referring to Figure 12) of extension dish 61 inserted in the guide groove 115 respectively, the glide direction of extension dish 61 was adjusted to first direction 36 and second direction 37.

As Figure 15 and shown in Figure 16, the end face of disk body 56 is equipped with guide rail 98.Guide rail 98 is alternately arranged along the Width of disk body 56 with guide groove 115.Guide rail 98 is erect from the Surface Vertical of disk body 56.Guide rail 98 is arranged on the whole zone of disk body 56 and along first direction 36 and second direction 37 and extends.By guide rail 98 being inserted the guide groove 86 (referring to Figure 12) of extension dish 61, the glide direction of extension dish 61 is adjusted to first direction 36 and second direction 37.

Shown in Figure 11～14, extension dish 61 is the long rectangle of its Width.Extension dish 61 comprise the smooth planar section of formed end face 114 and with respect to planar section 114 towards the downward-sloping sloping portion 106 of first direction 36.

Planar section 114 has the opening 120 (referring to Figure 11 and Figure 23) that is arranged on rear end 122.Rear end 122 is extension dish 61 ends in opening 16 (referring to a Fig. 1 and Fig. 2) side.Opening 120 is arranged on the rear end 122 to end face 95 at the center on its Width from rear end surface 117.As Figure 12 and shown in Figure 14, the holding portion 127 that holds bracket panel 63 is arranged on the behind of planar section 114.The supporting slice 135 that holding portion 127 has sidewall 124 and extends along first direction 36 and second direction 37.Supporting slice 135 from the following distal process of sidewall 124 to the central authorities of planar section 114 on its Width.

Bracket panel 63 is rectangular, and the length of length of its Width (horizontal direction 74) and depth direction (first direction 36 and second direction 37) each other about equally.Bracket panel 63 is contained in the holding portion 127 and by supporting slice 135 and supports from the below.Bracket panel 63 is arranged to and can be slided along second direction 37 with respect to extension dish 61 from the state shown in Figure 12.Though do not show among the figure, by pulling out from extension dish 61 along second direction 37, bracket panel 63 is outstanding from rear end surface 117.Therefore, the paper placement surface in the extension dish 61 is extended towards second direction 37.

As Figure 12 and shown in Figure 14, form recess 129 on the back side of planar section 114.Recess 129 is the laterally long rectangle along disk body 114.Recess 129 is positioned at 122 places, rear end in the end of second direction 37 1 sides, and this recess open-ended in first direction 36 1 sides.The protuberance 113 (referring to Figure 12 and Figure 14) that is arranged in the disk body 56 is contained in respectively in the recess 129.Therefore, extension dish 61 by disk body 56 from supported underneath.

As shown in figure 12, the lug 58 (referring to Figure 11 and Figure 13) in the guide groove 115 of insertion disk body 56 is arranged on the back side (referring to Figure 11 and Figure 13) of the front end 96 of sloping portion 106.Formed lug 58 is outstanding downwards from the back side of front end 96.Position that lug 58 forms and the shape that has can be inserted in the guide groove 115 it respectively.

As shown in figure 12, the xsect guide groove 86 that is reverse U shape is formed on front end 96 1 sides at sloping portion 106 back sides.The guide rail 98 of disk body 56 (referring to Figure 11 and Figure 13) inserts respectively in the guide groove 86.Therefore, guide groove 86 is arranged on the position corresponding to guide rail 98.The lug 58 of extension dish 61 inserts respectively in the guide groove 115 of disk body 56, and the guide rail 98 of disk body 56 inserts respectively in the guide groove 86 of extension dish 61.Glide direction with extension dish 61 is adjusted to first direction 36 and second direction 37 like this.

Because in this mode disk body 56 and extension dish 61 are set, extension dish 61 can slide along first direction 36 and second direction 37 with respect to disk body 56.That is to say that the rear end 122 of extension dish 61 is configured to and can slides along first direction 36 and second direction 37.When extension dish 61 from its state (referring to Figure 13 and Figure 14) that is pushed into disk body 56 when second direction 37 is pulled out, the paper placement surface of paper discharge tray 21 obtains extending.On the contrary, when extension dish 61 from its state (referring to Figure 11 and Figure 12) that is drawn out disk body 56 with respect to disk body 56 when first direction 36 pushes, the paper placement surface withdrawal of sheet feed stacker 21.

Rotating shaft 35 allows disk body 56 to rotate up and down around the axle that along continuous straight runs 74 (referring to Fig. 6) extends by support holes 66 supportings.Because extension dish 61 is arranged in the disk body 56, can rotate towards sheet feed stacker 29 around the axle that along continuous straight runs 74 extends under the state that is not supported by rear end 112 rear end 122 of extension dish 61.

For example, when instruction in the composite set 10 began to read file, the image of file was read by scanning element 12.Print unit 20 is carried out print processing based on this document image.This print processing is carried out as follows.That is, the driving force of LF motor 85 (referring to Fig. 5) optionally is passed to paper feed roller 25, transfer roller 67 and exit roller 68.Therefore, the recording chart that is contained in the sheet feed stacker 29 transmits along transfer path 23.During recording chart transmitted, image was recorded on the recording chart by image recording unit 24, and this recording chart is discharged to space 40 (referring to Fig. 2) towards opening 16 then.

Figure 17 A and Figure 17 B are the side views of paper feeding cassette 52, and particularly, Figure 17 A demonstrates the state that paper disc 21 is in first attitude, and Figure 17 B demonstrates the state that paper disc 21 is in second attitude.Figure 18 is the schematic perspective view that shows paper feeding cassette 52, and wherein the attitude of paper discharge tray 21 changes second attitude into.Figure 19 A～19D shows that pushing extension along first direction 36 coils the attitude of 61 o'clock paper discharge tray 21 becomes the state of second attitude from first attitude synoptic diagram.

Because disk body 56 and extension dish 61 are constructed as described above, the attitude of paper discharge tray 21 can change between first attitude and second attitude.First attitude is that the end face 95 of rear end 122 of paper discharge tray 21 is basically by the state of horizontal support (for example, referring to Fig. 2,6,17A and Figure 19 A).In the present embodiment, under first attitude, the extension dish 61 of paper discharge tray 21 is arranged on end face 105 (referring to Fig. 7) top of sheet feed stacker 29.When rear end 122 was supported by rear end 112, paper discharge tray 21 kept first attitude.At length, when rear end 122 placed the end face 105 (referring to Fig. 7) of rear end 112 to go up, paper discharge tray 21 kept first attitude.In other words, when the bottom surface 99 of rear end 122 (for example, referring to Figure 11) during near end face 105, paper discharge tray 21 keeps first attitude.That is to say that first attitude is the mobile adjusted state of rear end 122 towards sheet feed stacker 29.

Second attitude be the state that moves to sheet feed stacker 21 from above-mentioned first attitude of end face 95 (for example, referring to Figure 17 B, 18 and 19D).In the present embodiment, under second attitude, the bottom surface 99 of rear end 122 is positioned at end face 105 belows.Hereinafter will be described in detail second attitude.

Keep under the state of first attitude at paper discharge tray 21, recording chart can be discharged on the paper discharge tray 21.For example, as shown in Figure 6, under first attitude, the top of sheet feed stacker 29 is covered by paper discharge tray 21.Owing to this reason, prevent to enter sheet feed stacker 29 such as the dust that adheres to the paper powder on the recording chart that is contained in the paper discharge tray 21.

In the composite set 10 according to present embodiment, recording chart of document image is discharged to space 40 from the rear side (Figure 17 A is to the right side of 17C) of print unit 20 towards opening 16 on it.Owing to this reason, be used under the situation of print processing at undersized recording chart (hereinafter to be referred as " small size paper ") such as postcard, this small size paper places on the paper discharge tray 21 position (referring to Figure 17 A and 19A) away from opening 16.Under this situation, when the user pushes extension and coils 61 with respect to opening 16, take out the small size paper from paper discharge tray 21 and become easy.

Shown in Figure 17～19, extension dish 61 can push with respect to opening 16.Because disk body 56 is supported by disk body 54, thus extension dish 61 with respect to disk body 56 along first direction 36 slide (referring to Figure 19 A and 19B).When rear end 122 than rear end 112 further when first direction 36 slides (that is, extension dish 61 slides along first direction 36, makes rear end 122 be positioned at the downstream of rear end 112 with respect to first direction 36), the support of 112 pairs of rear ends 122, rear end is removed.Under small size paper was contained in state in the sheet feed stacker 29, opening 16 1 sides in the sheet feed stacker 29 produced the space 87 (referring to Figure 19) of not placing small size paper.Because extension dish 61 is arranged in the disk body 56, this extension dish can rotate towards sheet feed stacker 29 around the axle (referring to Fig. 6) that along continuous straight runs 74 extends.When the support of 112 pairs of rear ends 122, rear end was removed, disk body 56 can rotate towards sheet feed stacker 29, and extension dish 61 turns to space 87 (referring to Figure 19 B to 19D).Consequently, paper discharge tray 21 is in second attitude, and wherein the end face 95 of rear end 122 moves to sheet feed stacker 29, and its bottom surface 99 places end face 105 belows (referring to Figure 17 B, 18 and 19D) of rear end 112.When extension dish 61 with this mode with respect to the extension dish 59 of sheet feed stacker 29 when first direction 36 relatively moves, the attitude of paper discharge tray 21 can become second attitude from first attitude.

When the attitude of paper discharge tray 21 in the above described manner when first attitude becomes second attitude, extend downwards in the space of paper discharge tray 21 tops in the opening 16.In other words, allowing the user to put his/her hand into extends downwards with the space that taking-up is expelled to the recording chart of paper discharge tray 21.Shown in Figure 17 A and 17B, when the attitude of paper discharge tray 21 changed second attitude into, the height in the space in the opening 16 became H2 from H1 (paper discharge tray 21 is in the height under the state of first attitude).Based on this reason, the user can put his/her hand into ratio open 16 a darker side.Consequently, even the recording chart that is discharged on the paper discharge tray 21 is a small size paper, the user still can easily take out recording chart from paper discharge tray 21.Therefore, the user can not run into the inconvenience that is difficult to from paper discharge tray 21 taking-up recording charts, and height (height of the cover 31) step-down by making opening 16, can make the composite set 10 of scanning element 12 and print unit two-layer setting about in the of 20 minutes thinner.The image recording structure that this point is equally applicable to according to this embodiment is the situation of single function printer.

(first modification of first embodiment)

Ring spring 131 (promoting the example (referring to Figure 19 A) of member) can be set in extension dish 59.Ring spring 131 flexibly promotes paper discharge tray 21, thereby the attitude of paper discharge tray is changed into first attitude from second attitude.The outside of the paper placement surface of second direction 37 1 side ends of 93 (referring to Fig. 7) bottom ring spring 131 is arranged on.Ring spring 131 does not show in figure such as Fig. 7.

Extension dish 61 can below shift space 87 in the sheet feed stacker 29 onto so that the user takes out small size paper (referring to Figure 19 A～19D) from paper discharge tray 21.That is, the attitude of paper discharge tray 21 is by becoming second attitude to its externally applied forces from first attitude.Ring spring 131 is compressed along with extension dish 61 descends, and gathers the spring force of releasing paper disc 21.When thereby the user discharges his/her hand when removing external force from extension dish 61, extension dish 61 rises because of the spring force that ring spring 131 gathers.When removing external force like this, paper discharge tray 21 recovers first attitude.

Though not shown, flipper guide 163 can be equipped with the tooth bar that extend at the center on Width.This tooth bar with cover be located at sheet feed stacker 160 on its Width in the heart pinion wheel be meshed.When any one the flipper guide along continuous straight runs 152 in two flipper guides 163 slided, another flipper guide slided along the direction opposite with the glide direction of this flipper guide in the mode of interlocking.Therefore, under the situation of the width that is positioned over the recording chart 247 on the sheet feed stacker 160 than the distance weak point between two flipper guides 163, slide by making one of flipper guide 163, these two flipper guides 163 promptly move simultaneously.Therefore, the center of recording chart 247 on its Width basically with the said reference position consistency.That is to say, even the recording chart 247 in being contained in sheet feed stacker 160 is under the situation of large scale paper 250 or small size paper 251, the center of recording chart 247 on its Width also basically with the said reference position consistency.

＜back guide 165 〉

As Figure 29 and shown in Figure 31, sheet feed stacker 160 is equipped with the back guide 165 (example of first adjustment means) of the align member that serves as the 4th embodiment.Back guide 165 is tabular component and edge conduct horizontal direction 152 extensions longitudinally.Back guide 165 has L-shaped basically vertical (directions of arrow 154 indications) xsect.Back guide 165 is regulated the recording chart 247 that is contained in the sheet feed stacker 160 and is moved towards opening 206 (directions of arrow 154 indications).In other words, back guide 165 near the tail end that is contained in the recording chart 247 in the sheet feed stacker 160 to regulate the position of this tail end.Though not shown, the bottom surface of sheet feed stacker 160 is equipped with the slit that extends along vertical (left side of Figure 29 and Figure 31, the right) of sheet feed stacker 160.Back guide 165 inserts this slit and therefore is configured to and can slide along this slit.The height of back guide 165 is arranged to make its upper end can be positioned at than protuberance 164 more near paper discharge tray 180 places (being positioned at protuberance 164 tops).Therefore, be arranged at back guide 165 under the state of primary importance (state shown in Figure 29), back guide 165 near the protuberance 185 of bracket panel 183 to support bracket panel 183.

When back guide 165 slided to the tail end 247 of recording chart, the tail end 247 of recording chart was near the guide surface of back guide 165.Therefore, the tail end 247 of recording chart is in alignment with each other.As Figure 29 and shown in Figure 31, recording chart 247 is contained in the sheet feed stacker 160, makes its tail end can be near back guide 165.Therefore, the front end of recording chart 247 is positioned at the precalculated position of sheet feed stacker 160, and is irrelevant with the size of recording chart 247.

＜the primary importance and the second place 〉

Back guide 165 is configured to and can moves between the primary importance and the second place.As shown in figure 29, primary importance is the position of large scale paper 250 with respect to sheet feed stacker 160 location.When the tail end of large scale paper 250 was regulated by the back guide 165 that is arranged at primary importance, this paper was positioned to make its front end can be near hang plate 222.As shown in figure 31, the second place is the position of small size paper 251 with respect to sheet feed stacker 160 location.When the tail end of small size paper 251 was regulated by the back guide 165 that is arranged on the second place, this paper was positioned to make its front end can be near hang plate 222.Back guide 165 slides according to the size that is contained in the recording chart 247 in the sheet feed stacker 160 and is arranged on the primary importance or the second place.Therefore, recording chart 247 is positioned at the position of its front end near hang plate 222, and is irrelevant with the size of recording chart.

＜paper discharge tray 180 〉

Shown in Figure 27 and Figure 29～31, paper discharge tray 180 has disk body 181 and is arranged on bracket panel 183 (example of bracket panel) in the cut-out 189 of disk body 181 (example of first disk body).

＜disk body 181 〉

When the part cut (referring to Figure 27 and Figure 30) of disk body 181 in opening 206 1 sides (directions of arrow 154 indications), formed disk body 181 is spill basically on planimetric map.Though not shown, disk body 181 is equipped with rotating shaft.This rotating shaft is separately positioned on the two ends of disk body 181 at the front end 187 of its Width (horizontal direction 152).When rotating shaft was inserted in the support holes that is provided with in the sidewall 167 of sheet feed stacker 160 respectively, axially going up that supported paper discharge tray 181 can extend around the Width along sheet feed stacker 160 rotated.The width setup of disk body 181 is for approximating the distance between the two side 167 greatly.Owing to this reason, under the state that disk body 181 falls with respect to sheet feed stacker 160, disk body 181 is stably supported by sidewall 167.

＜bracket panel 183 〉

Bracket panel 183 has almost the shape identical with cut-out 189 on planimetric map, and forms and be slightly smaller than cut-out 189.Bracket panel 183 is arranged to make the width of its along continuous straight runs 152 can be greater than the width (referring to Figure 33) of small size paper 251.Bracket panel 183 is arranged in the cut-out 189 of disk body 181 (referring to Figure 27).Rotating shaft 184 projects to the outside of bracket panel 183 on its Width, and 152 ends (referring to Figure 27) that are arranged on bracket panel 183 in the horizontal direction.Though not shown, the support holes of supporting revolving shaft 184 is arranged at the position corresponding to the rotating shaft in the disk body 181 184 rotationally.When rotating shaft 184 was supported by support holes, bracket panel 183 was arranged in the disk body 181 and can rotates towards sheet feed stacker 160.Omitted rotating shaft 184 among Figure 30.

Shown in Figure 29 and 31, recess 186 is arranged on the back side of bracket panel 183.Formed recess 186 makes the front end (right side of Figure 29 and Figure 31) of bracket panel 183 can be recessed towards the end face of bracket panel 183.Therefore, under the state that sheet feed stacker 160 is rotated, a part that is arranged at the back guide 165 of the second place is contained in (referring to Figure 31) in the recess 186 at bracket panel 183.Protuberance 185 is arranged on the back side of bracket panel 183.Formed recess 186 makes the front end (left side of Figure 29 and Figure 31) of bracket panel 183 can be recessed towards the end face 160 of bracket panel.Protuberance 185 is arranged on the position corresponding to the protuberance 164 that is provided with on the sheet feed stacker 160.

By above-mentioned structure, paper discharge tray 180 is configured to make the attitude of bracket panel 183 to change between first attitude and second attitude.First attitude is the state that the end face 193 of the rear end 196 (corresponding to the second end of opening one side) of bracket panel 183 is supported on predetermined altitude (referring to Figure 27).In this first attitude, the height of the end face 193 of the rear end 196 almost height with the end face 191 of disk body 181 is identical.That is to say that end face 193 and end face 191 form same flat surface.Second attitude is that the end face 193 of the rear end 196 of bracket panel 183 has moved the state of (referring to Figure 30) towards sheet feed stacker 160 with respect to first attitude.

＜the first attitude 〉

Under large scale paper 250 was contained in situation in the sheet feed stacker 160, back guide 165 was arranged at primary importance (referring to Figure 29).Under this state, as shown in figure 29, the protuberance 185 of bracket panel 183 is near the end face of back guide 165, and bracket panel 183 is supported by back guide 165.So just regulate of the rotation of the rear end 196 of bracket panel 183, therefore keep bracket panel to be in first attitude towards sheet feed stacker 160.Be arranged in this mode under the state of primary importance at back guide 165, bracket panel 183 changes adjusted from the attitude of first attitude to the second attitude.

＜the second attitude 〉

Under small size paper 251 was contained in situation in the sheet feed stacker 160, the back guide 165 that is arranged at primary importance slidably moved to the second place (referring to Figure 29 and Figure 31).Along with moving of back guide 165, the support of 165 pairs of bracket panels 183 of back guide is removed.Only the rotating shaft 184 of bracket panel 183 is supported by disk body 181 rotationally.In addition, the recess 186 that can hold the back guide 165 that is arranged at the second place is arranged at the back side of bracket panel 183.Owing to this reason, bracket panel 183 is owing to its weight is rotated towards sheet feed stacker 160.When bracket panel 183 when sheet feed stacker 160 is rotated, as shown in figure 31, protuberance 185 is near protuberance 164.Consequently, bracket panel 183 is in second attitude by protuberance 164 supports of sheet feed stacker 160.When back guide 165 was arranged at the second place in this mode, the attitude of the bracket panel 183 of paper discharge tray 180 became second attitude because of the weight of bracket panel 183 from first attitude.Along with this attitude changes, the situation when keeping first attitude with bracket panel 183 is compared, and end face 193 moves (Figure 27 and 30) towards sheet feed stacker 160.

The operating effect of＜present embodiment 〉

Figure 32 is the schematic perspective view that shows paper feeding cassette 150 when large scale paper 250 is discharged to paper discharge tray 180.Figure 33 is the schematic perspective view that shows paper feeding cassette 150 when small size paper 251 is discharged to paper discharge tray 180.Figure 34 A and 34B are the longitudinal sectional views of paper feeding cassette 150, and particularly, Figure 34 A shows that bracket panel 183 keeps the state of first attitude, and Figure 34 B shows that bracket panel 183 keeps the state of second attitude.

For example, when instruction in the composite set 200 began to read file, the image of file was read by scanning element 202.Print unit 20 is carried out print processing based on the image of this document.This print processing is carried out as follows.That is, the driving force of LF motor optionally is passed to paper feed roller shown in Figure 28 231, transfer roller 233 and exit roller 235.Therefore, the recording chart 247 that is contained in the sheet feed stacker 160 transmits along transfer path 223.During the transmission of recording chart 247, image is recorded on the recording chart 247 by image recording unit 224, and recording chart 247 is discharged to space 260 (referring to Figure 34) towards opening 206 then.

Shown in Figure 32 and Figure 34 A, be discharged under the situation of paper discharge tray 180 at large scale paper 250 as recording chart 247, recording chart 250 is contained in the paper discharge tray 180 under its part is exposed to the state in opening 206 outsides.Therefore, the user can easily take out the large scale paper 250 that is contained in the paper discharge tray 180 from paper discharge tray 180.

Be arranged at back guide 165 under the state of primary importance, the rotation of the rear end 196 of bracket panel 183 is regulated by back guide 165, and bracket panel 183 keeps first attitude.When back guide 165 was arranged at the second place, bracket panel 183 can rotate towards sheet feed stacker 160.Be discharged under the situation of paper discharge tray 180 at the small size paper 251 as recording chart 247, shown in Figure 33 and Figure 34 B, recording chart 251 is discharged to depth one side of opening 206.When back guide 165 was arranged at the second place, paper discharge tray 180 turned in the sheet feed stacker 160.Therefore, extend to the below of cut-out 189 in the space of paper discharge tray 180 tops.In other words, allowing the user his/her hand to be put into so that take out the space of the small size paper 251 that is expelled to paper discharge tray 180 extends downwards.

Shown in Figure 34 A and Figure 34 B, when the attitude of bracket panel 183 changed second attitude into, the height in the space in the opening 206 became H12 from H11 (bracket panel 183 is in the height under the state of first attitude).Owing to this reason, the user can be put into farther depth one side of ratio open 206 to his/her hand.Consequently, even the recording chart 247 that is discharged on the paper discharge tray 180 is a small size paper 251, the user also can easily take out small size paper 251 from paper discharge tray 180.Therefore, the user can not run into the inconvenience that is difficult to from paper discharge tray 180 taking-up recording charts 247, and can make scanner and printer divide the device of two-layer setting up and down to do thinlyyer by the height reduction that makes opening 206.Even at composite set 200 is only to have under the situation of single function printer of printing function also can show same effect.

As under the situation of recording chart 247, under the state that sheet feed stacker 160 is rotated, small size paper 251 is discharged to paper discharge tray 180 at bracket panel 183 at small size paper 251.The width of bracket panel 183 along continuous straight runs 152 direction of paper surface (among the Figure 34 perpendicular to) is greater than the width of small size paper 251.In addition, because the small size paper 251 that is contained in the sheet feed stacker 160 carries out the center alignment by flipper guide 163, small size paper 251 of document image is discharged to paper discharge tray 180 center on 152 in the horizontal direction on it.Owing to this reason, the both sides of small size paper 251 be can't help that disk body 181 supports and are only supported by bracket panel 183.The small size paper 251 of therefore, being discharged slides towards opening 206 along the bracket panel 183 that tilts.Consequently, the taking-up of small size paper 251 becomes than being easier to.

In addition, be arranged in this mode under the state of the second place (referring to Figure 31) at back guide 165, bracket panel 183 keeps second attitude because of its deadweight.That is to say that under small size paper 251 was contained in situation in the sheet feed stacker 160, always moved towards sheet feed stacker 160 rear end 196 of bracket panel 183.Compare with the situation of discharging large scale paper 250, so just improved from the visuality of fuselage 205 outsides to opening 206 inside.Consequently, the user can confirm easily that the small size paper 251 that is expelled to depth one side in opening 206 is contained in the paper discharge tray 180, need not observe the inboard of opening 206.In addition, bracket panel 183 is not in not corresponding with the size of recording chart 247 attitude.That is to say that under large scale paper 250 was contained in state in the sheet feed stacker 160, bracket panel 183 kept first attitude by the back guide 165 that is arranged at primary importance.In addition, under small size paper 251 was contained in state in the sheet feed stacker 160, bracket panel 183 kept second attitude because back guide 165 is arranged at the second place.Based on this reason, the user can determine the size of recording chart 247 from the attitude of bracket panel 183.

Bracket panel 183 can comprise spring (example of elastic component), so that the attitude of bracket panel 183 can change to first attitude from second attitude.For example, the rotating shaft 184 of bracket panel 183 is equipped with the torsion ring spring respectively.Under this situation, because bracket panel 183 keeps first attitude because of the elastic force of torsion ring spring, the attitude of bracket panel is by becoming second attitude to its externally applied forces from first attitude.Since bracket panel 183 by from the second attitude resiliency urged to first attitude, when external force is removed, bracket panel 183 recoveries first attitude.Based on this reason, bracket panel 183 only just is in second attitude under by the situation that pushes away under the user.Under another state, the end face of sheet feed stacker 160 is covered to prevent that dust from entering sheet feed stacker 160.

(the 5th embodiment)

Hereinafter will be described the fifth embodiment of the present invention.Except the local difference of the structure of paper feeding cassette 150, have and the 4th embodiment identical construction according to the composite set 200 of the 5th embodiment.Based on this reason, omit description to other structures outside the paper feeding cassette 150.In the 4th embodiment, back guide 165 has the function of align member, and in the 5th embodiment, then is that flipper guide 263 plays align member.

＜disk body 254 〉

As shown in figure 36, disk body 254 has and disk body 181 (referring to Figure 27) shape much at one.As Figure 38, shown in 39,42 and 43, disk body 254 has the recess 272 that forms at its back side.Recess 272 is the vertically relatively long rectangle along disk body 254.As Figure 36, Figure 39 and shown in Figure 43, disk body 254 is equipped with from the outstanding sidewall 287 in the below of the two side direction disk bodies 254 of disk body on its Width (horizontal direction 152).As Figure 36, Figure 38 and shown in Figure 42, disk body 254 is equipped with the antetheca of giving prominence to the below of disk body 254 in the end of opening 206 1 sides (directions of arrow 154 indications) from disk body 288.Under the state that disk body 254 falls with respect to sheet feed stacker 160, sidewall 287 supports (referring to Figure 35) by sidewall 167, and antetheca 288 is supported by antetheca 168.About this disk body 254, the center of disk body 254 (side (referring to Figure 36) of cut-out 169) is not equipped with wall surface.Based on this reason, as shown in figure 39, keep at bracket panel 256 under the state of first attitude (referring to Figure 35 and 37), an arm 269 and a part of 270 are contained in the recess 272.

＜the primary importance and the second place 〉

Flipper guide 263 is configured to and can moves between the primary importance (referring to Figure 35 and 14) and the second place (referring to Figure 40 and 43).Shown in Figure 35 and 39, primary importance is the position of large scale paper 250 with respect to sheet feed stacker 160 location.The both sides of large scale paper 250 on its Width are regulated by the flipper guide 263 that is arranged at primary importance.Therefore, the position of recording chart 247 on its Width is consistent with predetermined reference position (being the center of sheet feed stacker 160 on its Width in the present embodiment) basically.Shown in Figure 40 and 43, the second place is the position of small size paper 251 with respect to sheet feed stacker 160 location.The both sides of small size paper 251 on its Width are regulated by the flipper guide 263 that is arranged at the second place.Therefore, the position of small size paper 251 on its Width basically with the said reference position consistency.Flipper guide 263 is arranged on the primary importance or the second place according to the size that is contained in the recording chart 247 in the sheet feed stacker 160.Therefore, recording chart 247 is defined in the center of sheet feed stacker 160 on its Width in the position on its Width, and is irrelevant with the size of recording chart.

Paper discharge tray 180 in the present embodiment is configured to make the attitude of bracket panel 256 to change between first attitude and second attitude.First attitude is the state that the end face 193 of the rear end 196 of bracket panel 256 is supported on predetermined altitude (referring to Figure 35,37 and 39).In this first attitude, as shown in figure 39, the height of the height of the end face 193 of rear end 196 and the end face 191 of disk body 254 much at one.That is to say that end face 193 and end face 191 form same flat surface.Second attitude is that the end face 193 of the rear end 196 of bracket panel 256 has moved the state of (referring to Figure 40,41 and 43) towards sheet feed stacker 160 with respect to first attitude.

＜the first attitude 〉

Under large scale paper 250 was contained in situation in the sheet feed stacker 160, flipper guide 263 was arranged at primary importance (referring to Figure 35).Under this state, as shown in figure 39, the arm 269 of

bracket panel

256 and 270 supports near the end face of flipper guide 263 and by flipper guide 263.So just regulate of the rotation of the rear end 196 of bracket panel 256, therefore keep bracket panel to be in first attitude towards sheet feed stacker 160.Like this, be arranged at flipper guide 263 under the state of primary importance, bracket panel 256 changes adjusted from first attitude to the attitude of second attitude.

＜the second attitude 〉

Under small size paper 251 was contained in situation in the sheet feed stacker 160, the flipper guide 263 that is arranged at primary importance slidably moved on to the second place (referring to Figure 35,39,40 and 43) from primary importance.Along with moving of flipper guide 263,263 pairs of arms 269 of flipper guide and 270 support are removed.Only the rotating shaft 184 of bracket panel 256 is supported rotationally by disk body 254.Owing to this reason, bracket panel 256 rotates towards sheet feed stacker 160 because of its weight.When bracket panel 256 when sheet feed stacker 160 is rotated, as shown in figure 43, the protuberance 259 of bracket panel body 267 is near the end face 263 of flipper guide.Consequently, bracket panel 256 is in second attitude by flipper guide 263 supports of sheet feed stacker 160.When flipper guide 263 was arranged at the second place in this mode, the attitude of the bracket panel 256 of paper discharge tray 180 became second attitude because of the weight of bracket panel 256 from first attitude.

The operating effect of＜present embodiment 〉

Figure 44 A and 44B are the longitudinal sectional views of paper feeding cassette 150, and particularly, Figure 44 A shows that bracket panel 256 keeps the state of first attitude, and Figure 44 B shows that bracket panel 256 keeps the state of second attitude.

Shown in Figure 44 A and Figure 44 B, be discharged under the situation of paper discharge tray 180 at large scale paper 250 as recording chart 247, large scale paper 250 is contained in the paper discharge tray 180 under its part is exposed to the state in opening 206 outsides.Therefore, the user can easily take out the large scale paper 250 that is contained in the paper discharge tray 180 from paper discharge tray 180.

Be arranged at flipper guide 263 under the state of primary importance, the rotation of the rear end 196 of bracket panel 256 is regulated by flipper guide 263, and bracket panel 256 keeps first attitude.When flipper guide 263 was arranged at the second place, bracket panel 256 can rotate towards sheet feed stacker 160.Shown in Figure 44 B, be discharged under the situation of paper discharge tray 180 at small size paper 251 as recording chart 247, small size paper 251 is discharged to depth one side of opening 206.When flipper guide 263 was arranged at the second place, paper discharge tray 180 turned in the sheet feed stacker 160.Therefore, extend to the below of cut-out 169 in the space of paper discharge tray 180 tops.In other words, allowing the user his/her hand to be put into so that take out the space of the small size paper 251 that is expelled to paper discharge tray 180 extends downwards.

Shown in Figure 44 A and Figure 44 B, when the attitude of bracket panel 256 changed second attitude into, the height in the space in the opening 206 became H14 from H13 (bracket panel 256 is in the height under the state of first attitude).Owing to this reason, the user can be put into farther depth one side of ratio open 206 to his/her hand.Consequently, even the recording chart 247 that is discharged on the paper discharge tray 180 is a small size paper 251, the user also can easily take out small size paper 251 from paper discharge tray 180.Therefore, the user can not run into the inconvenience that is difficult to from paper discharge tray 180 taking-up recording charts 247, and can make scanner and printer divide the device of two-layer setting up and down to do thinlyyer by the height reduction that makes opening 206.Even at composite set 200 is only to have under the situation of single function printer of printing function also can show same effect.

In addition, under the state that sheet feed stacker 160 is rotated, small size paper 251 is discharged to paper discharge tray 180 at bracket panel 256.The width of bracket panel 256 is greater than the width of small size paper 251.In addition, because the small size paper 251 that is contained in the sheet feed stacker 160 carries out the center alignment by flipper guide 163, small size paper 251 of document image is discharged to the paper discharge tray 180 almost center on 152 in the horizontal direction on it.Owing to this reason, the both sides of small size paper 251 are not supported by disk body 254, and are only supported by bracket panel 256.Owing to this reason, the small size paper 251 of being discharged slides towards opening 206 along bracket panel 256.Consequently, the taking-up of small size paper 251 becomes than being easier to.

In addition, be arranged at flipper guide 263 under the state of the second place, bracket panel 256 keeps second attitude because of its deadweight.That is to say that under small size paper 251 was contained in situation in the sheet feed stacker 160, always moved towards sheet feed stacker 160 rear end 196 of bracket panel 256.Compare with the situation of discharging large scale paper 250, so just improved from the visuality of fuselage 205 lateral openings 206 inside.Consequently, the user can confirm easily that the small size paper 251 that is expelled to depth one side in opening 206 is contained in the paper discharge tray 180, need not to observe the inboard of opening 206.In addition, bracket panel 256 is not in and the not corresponding attitude of the size of recording chart 247.That is to say, be contained at large scale paper 250 that bracket panel 256 keeps first attitude under the state in the sheet feed stacker 160, and be contained at small size paper 251 that bracket panel 256 keeps second attitude under the state in the sheet feed stacker 160.Owing to this reason, the user can determine the size of recording chart 247 from the attitude of bracket panel 256.

Bracket panel 256 can comprise spring (example of elastic component), so that the attitude of bracket panel 256 can change to first attitude from second attitude.For example, the rotating shaft 184 of bracket panel 256 is equipped with the torsion ring spring respectively.Under this situation, because bracket panel 256 keeps first attitude because of the elastic force of torsion ring spring, the attitude of bracket panel is by becoming second attitude to its externally applied forces from first attitude.Since bracket panel 256 by from the second attitude resiliency urged to first attitude, therefore when external force is removed, bracket panel 256 recoveries first attitude.Based on this reason, bracket panel 256 only just is in second attitude under by the situation that pushes away under the user.Under another state, the end face of sheet feed stacker 160 is covered to prevent that dust from entering sheet feed stacker 160.

Further, though in the 4th and the 5th embodiment, described paper discharge tray 180 parts towards sheet feed stacker 160 rotate and its attitude from first attitude become second attitude aspect, paper discharge tray 180 can be configured to keep its horizontal attitude when sheet feed stacker 160 falls.For example, the paper discharge tray of describing among the 4th embodiment 180 can be configured to make disk body 181 and bracket panel 183 integrally to move towards sheet feed stacker 160.For example, the paper discharge tray of describing among the 5th embodiment 180 can be configured to make disk body 254 and bracket panel body 256 integrally to move towards sheet feed stacker 160.That is to say that in the present invention, paper discharge tray 180 is not limited to the rotation of paper discharge tray 180 from first attitude to the attitude change of second attitude, and can be the slip of paper discharge tray 180 towards sheet feed stacker 160.

In addition, the width of bracket panel 183,256 along continuous straight runs 152 is less than the width of small size paper 251.Yet, in as the foregoing description, making under the situation of width greater than the width of small size paper 251 of bracket panel 183,256 along continuous straight runs 152, small size paper 251 slides towards opening 206.Consequently, taking out small size paper 251 from paper discharge tray 180 becomes and is easier to.Therefore, the width of best bracket panel 183,256 along continuous straight runs 152 is greater than the width of small size paper 251.

In addition, allow to be arranged on for example side of main frame body 205 from the opening 206 that paper discharge tray 180 takes out recording chart 247.Yet for the ease of taking out recording chart 24, preferably opening 20 is arranged on the front 156 of the main frame body 205 that is provided with guidance panel 204.
