Connection unit 23 comprise flexibility (flexible) coupling part 24 and can bias voltage manual feed tray 21 can be lifted to the biased sections 25 of printer body 101 side (apparatus body side).The coupling part 24 of present embodiment is the coupling mechanism be made up of the first coupling components 24a and the second coupling components 24b, one end of described first coupling components is supported rotationally by printer body 101, and described second coupling components is connected to the other end of the first coupling components 24a.Biased sections 25 is made up of biasing spring (biasing member) 26 and slide mechanism 27, described biasing spring is connected to the other end of the second coupling components 24b, and described slide mechanism makes the other end of the second coupling components 24b slide with being basically parallel to the stack surface 21c of manual feed tray 21.Biasing spring 26 is coil springs.
One end of first coupling components 24a is supported on the top of the dish rotating shaft 21a of manual feed tray 21 rotationally by printer body 101.The other end of the first coupling components 24a is connected flexibly by coupling spindle 28 one end with the second coupling components 24b.One end (first end) of biasing spring 26 is connected to the other end of the second coupling components 24b, and the other end of biasing spring 26 is connected to the end 21b of manual feed tray 21.Then, biasing spring 26 by the second coupling components 24b bias voltage so that towards manual feed tray 21 end 21b layback move.Therefore, the coupling part 24 be made up of the first and second coupling components 24a and 24b is configured so that coupling part 24 can bend when door 102 and manual feed tray 21 are opened/closed or extend.
As mentioned above, the first end of biasing spring 26 is fixed to printer body 101 by coupling part 24, and the second end of biasing spring is fixed to manual feed tray 21, to make biasing spring 26 upwards pull manual feed tray 21 when door 102 is opened, as hereinafter by describing in detail.In other words, manual feed tray 21 is drawn to printer body side by the biasing force produced when the state Xiamen 102 be opened in manual feed tray 21 is opened by biasing spring 26, and at least when door 102 is opened to the first pivot angle α, the pivot angle that manual feed tray 21 and door 102 are formed is reduced to the pivot angle being less than the second pivot angle β.Therefore, the biasing force of biasing spring 26 is stronger, more tends towards stability in the position of manual feed tray 21.But, if biasing force is too strong, manual feed tray 21 may with open door 102 operations linkage takeoff.Thus, the biasing force of biasing spring 26 is set to that making the position of manual feed tray 21 can maintain sheet material S is fully loaded the state in manual feed tray 21.Such as, the power of about 30N using enough as the maximum load weight of the weight and sheet material S that upwards pull manual feed tray 21 total weight needed for power, and the biasing force of biasing spring 26 is arranged on 30N in the present embodiment.
The projection 27a that the other end that slide mechanism 27 is included in the second coupling components 24b is arranged and slide unit 27b, slide unit 27b is formed sliding tray 27c, and the manual feed tray 21c that projection 27a (other end of the second coupling components 24b) is basically parallel to manual feed tray 21 by sliding tray 27c slides.Although slide unit 27b is attached to manual feed tray 21, slide unit 27b can be integrally formed with manual feed tray 21.
Next, except Fig. 1, the operation (action) of the manual feed tray 21 when the state Xiamen 102 be opened in manual feed tray 21 is opened is described with reference to Fig. 5 to 7.Fig. 5 is the schematic cross sectional views of equipment, illustrate that sheet material S is stacked on the state in the manual feed tray 21 of chopping machine 100, Fig. 6 is the schematic cross sectional views of equipment, illustrate that the state Xiamen 102 be opened in the manual feed tray 21 of stacking sheet material S is opened the state of about half, and Fig. 7 is the schematic cross sectional views of equipment, the state that the state Xiamen 102 be opened in the manual feed tray 21 of stacking sheet material S is opened is shown.
As shown in Figure 1, under the state that manual feed tray 21 is stored in door 102, the first and second coupling components 24a and 24b bend at coupling spindle 28 place, and are configured in the storage not disturbing manual feed tray 21 near position each other.Biasing spring 26 shrinks and projection 27a (other end of the second coupling components 24b) is positioned at the front edge side of sliding tray 27c.
When from this state pull-out manual feed tray 21, the rotation of the second coupling components 24b and manual feed tray 21 is rotated in linkage centered by coupling spindle 28, and when the end on manual dish 21 side of arm member 20A1 of coiling pivot angle restricted part 20A slides into the slip restriction site on reveal as shown in Figure 5, the rotation of manual feed tray 21 is stopped.Biasing spring 26 also at this moment shrinks and projection 27a (other end of the second coupling components 24b) is positioned at the front edge of sliding tray 27c.Coupling part 24 remains in case of bending, because the dish rotating shaft 21a of the door pivot 103 of door 102 and manual feed tray 21 is positioned at same position with regard to the horizontal direction (horizontal direction in Fig. 4) of printer body 101.In other words, when manual feed tray 21 is just opened/closed, the slewing area of manual feed tray 21 does not have coupled unit 23 to limit and connection unit 23 does not disturb the rotation of manual feed tray 21.
In this state, the first and second coupling components 24a and 24b bend and coupling spindle 28 is located close to the manual feed tray 21c of manual feed tray 21.In other words, the first coupling components 24a to locate and the second coupling components 24b locates along manual feed tray 21 along printer body 101.Therefore, the first and second coupling components 24a and 24b do not disturb user stacking sheet material S in manual feed tray 21.
When door 102 rotates from this state along opening direction, the first and second coupling components 24a and 24b stretch when manual feed tray 21 is separated with printer body 101.This is because the dish rotating shaft 21a of manual feed tray 21 separates along the right-hand side (right-hand side in Fig. 4) of printer body 101 gradually relative to the door pivot 103 of door 102.Thus, the first and second coupling components 24a and 24b be bent substantially straighten gradually during door 102 is opened to its maximum opening angle, that is, extend to extreme length.When door 102 rotates further from the state that the first and second coupling components 24a and 24b straighten substantially, the other end (projection 27a) of the second coupling components 24b moves to dish rotating shaft 21a side by the biasing force of resisting biasing spring 26 along sliding tray 27c and pulls biasing spring 26.
When door 102 be opened as illustrated in fig. 6 about half (α/2) time, rotate together with the moving down of manual feed tray 21 and door 102 under the state that manual feed tray 21 is limited in specific angle (70 °) by dish pivot angle restricted part 20A.At this moment, the first and second coupling components 24a and 24b stretch from case of bending, and connection unit 23 is stretched over its extreme length.Until when connection unit 23 is stretched over its extreme length, opening the inclination of the dish pivot angle restricted part 20A limit manual feed tray 21 arranged in door 102, because the first and second coupling components 24a and 24b are configured to the opening operation not disturbing manual feed tray 21.Thus, the relative angle between manual feed tray 21 and ground is opened due to door 102 and reduces.Although this relative angle also depends on the relation between first and second coupling components 24a and 24b etc., the relative angle that manual feed tray 21 and ground are formed changes in the present embodiment in the scope of 20 ° to 5 °.
Note, although be maximized in the be opened length of about one half connection unit 23 of door 102 as illustrated in fig. 6 in the present embodiment, when connection unit 23 is stretched over its extreme length, the opening angle of door 102 is not limited to this.When connection unit 23 is stretched over its extreme length, the opening angle of door 102 can be set as any angle, as long as it is less than the angle when door 102 is opened to maximum.
As shown in Figure 7, when door 102 rotates further, because connection unit 23 has been stretched over its extreme length, the other end (projection 27a) of the second coupling components 24b moves to the cardinal extremity of sliding tray 27c (dish rotating shaft 21a side).Biasing spring 26 stretches due to this movement of the projection 27a of the second coupling components 24b.
When biasing spring 26 is stretched over its extreme length, namely, when connection unit 23 is stretched over its extreme length, by the biasing force (elastic force) of biasing spring 26, power acts in manual feed tray 21 along making manual feed tray 21 to coil the direction being lifted to door 102 side centered by rotating shaft 21a.Thus, manual feed tray 21 strongly rises, thus than original state (state in Fig. 7) more near door 102.When manual feed tray 21 rises, even if sheet material S stacking in manual feed tray 21 is offset also move to manual donor rollers to 22 sides.
As mentioned above, chopping machine 100 according to the present embodiment, because biasing spring 26 is arranged in connection unit 23, so manual feed tray 21 can by suitably lifting before door 102 is opened to finally.Thus, the sheet material S in manual feed tray 21 can not drop when door 102 is opened, even and if the stacked position of sheet material S offset from supply position, sheet material S also can turn back to supply position.Thus, the supply jam caused by the skew of the supply position of sheet material S can be prevented.
And, by arranging biasing spring 26 in connection unit 23, the vibrations acted on when user strongly opens door 102 in manual feed tray 21 can be cushioned.Therefore, reliably can prevent the sheet material S in manual feed tray 21 from dropping, and reduce the position skew occurring sheet material S.
By arranging biasing spring 26 in connection unit 23, the operation that also can make to perform when switching the moving direction of manual feed tray 21 operation of manual feed tray (when upwards the rotating from the state shown in Fig. 7 in the present embodiment) is carried out smoothly.Therefore, unnecessary sound and vibrations can be reduced.
The chopping machine 100 of present embodiment uses slide unit 27b and the first and second coupling components 24a and 24b as coupling part 24.Therefore, the first and second coupling components 24a and 24b such as will not disturb user stacking sheet material S in manual feed tray 21.
The other end (other end of connector group) that the chopping machine 100 of present embodiment is configured so that the second coupling components 24b is slidably and by along a direction bias voltage.Therefore, connector can be made a response flexibly and strictly can not be limited in the position of the center of turn of the length of connector, corresponding component etc.In other words, connector makes it possible to the restriction tackled flexibly about part design and particularity.
As mentioned above, no matter the chopping machine of present embodiment 100 is that the opening/closing operation of door 102 can the pivot angle of suitably limit manual feed tray 21, and can prevent dropping and position skew of sheet material S stacking in manual feed tray 21.
Although present embodiment of the present invention has been described, the present invention has been not limited to present embodiment described above.And the beneficial effect described in present embodiment of the present invention only enumerates the most suitable effect brought by the present invention, and effect of the present invention is not limited to the description in present embodiment of the present invention.
Such as, although by utilizing manual supply portion 20 to describe present embodiment as sheet-stacking part, the present invention has not been limited to this.When the discharge sheet-stacking dish (sheet-stacking dish) of stacking sheet material S (image has been formed on sheet material S and sheet material S discharges from equipment) be arranged on can the door inside exposure device body time, sheet-stacking part described above can be applied to the discharge sheet-stacking part having and discharge sheet-stacking dish.
