Synchronous change paper feeding track.Hereinafter, this is described in detail in combination with Fig. 7~Fig. 9.It should be noted that in order to make it easy to understand,
Image forming part 130, the first paper sheet cassette 123,124 first paper supply support of the second paper sheet cassette are only schematically illustrated in figure 6
Disk 125 and the second paper supply tray 126, and in order to make it easy to understand, omitting the diagram of these components in the other drawings.
As shown in fig. 7, in the case of normal paper feeding, hand send the angle of paper supply tray 101 when being 0 °, the paper transported
Either thin paper or ground paper, paper can carry out paper feeding operation normal through upper paper feeding track 103.At this point, paper along
Upper paper feeding track 103 (such as along direction shown in dotted arrow in figure), from hand send paper supply tray 101 via feeding-in roll 100,
Feeding-in roll pair 106 reaches usual transport path 102, is finally transported to image forming part 130.
When failure has occurred such as paperboard or device surrounding space deficiency leads to not make hand in upper paper feeding track 103
When the angle of paper supply tray 101 being sent to remain 0 °, the angle that hand send paper supply tray 101 can be adjusted, control unit control at this time is removed
Send portion's synchronous change paper feeding track.Such as shown in Fig. 8, hand send the angle of paper supply tray 101 to be changed to 30 °, at this point, sending confession with hand
The angle change of paper pallet 101 is corresponding, and control unit controls feeding-in roll 100 and 106 synchronous rotary of feeding-in roll pair and is moved to
The position opposed with middle paper feeding track 104.Paper along middle paper feeding track 104 (such as along shown in dotted arrow in figure side
To), it send paper supply tray 101 to be transported to feeding-in roll pair 107 via feeding-in roll 100, feeding-in roll pair 106 from hand and advances to paper supply
Carton side.Paper changes direction of advance later, is returned to usual transport path 102, last edge via feeding-in roll pair 107 again
It usual transport path 102 and is transported to image forming part 130.
Space further reduces need to further change hand send the angle of paper supply tray 101 in the case of, such as Fig. 9 institutes
Show, hand send the angle of paper supply tray 101 to be changed to 65 °, at this point, sending the angle change of paper supply tray 101 corresponding with hand, controls
Portion controls feeding-in roll 100 and 106 synchronous rotary of feeding-in roll pair and is moved to the position opposed with lower paper feeding track 105.Paper
Along lower paper feeding track 105 (such as along direction shown in dotted arrow in figure), send paper supply tray 101 via feeding-in roll from hand
100, feeding-in roll pair 106 is transported to feeding-in roll pair 108 and advances to paper sheet cassette side.Paper changes direction of advance later, then
It is secondary to be returned to usual transport path 102 via feeding-in roll pair 108, it is transported to image finally along usual transport path 102
Forming portion 130.
It should be noted that feeding-in roll pair 106 send paper supply tray 101 to link and rotates synchronously with hand.Concrete example is as shown in Figure 10,
Feeding-in roll pair 106 is connect by linkage belt 110 with the drive shaft 111 for driving hand that paper supply tray 101 is sent to rotate, and paper supply is sent in hand
Pallet 101 rotate when, drive shaft 111 via linkage belt 110 drive feeding-in roll pair 106 rotate synchronously to corresponding carrying channel
The corresponding position of diameter.But not limited to this, can also increase other feeding-in rolls pair in the position of corresponding angle, so as to
Feeding-in roll pair 106 is set to send the angle of paper supply tray 101 no longer to correspond with hand.
So, for example, when it is 30 ° that hand, which send the angle of paper supply tray 101, paper can not only walk middle paper feeding
Track 104 can also actually go on paper feeding track 103, and control unit individually controls the position of feeding-in roll pair 106 and above send at this time
Paper track 103 is opposed.Equally, when it is 65 ° that hand, which send the angle of paper supply tray 101, paper can not only go down paper feeding rail
Road 105 can also walk middle paper feeding track 104, can also go on paper feeding track 103.In the case where paper is thin paper, paper
Suppleness is preferable, so even be passed through zig zag transport path also there is no problem.For this paper mold, as described above
If changing paper feeding track, transport path can not only be shortened, save the time, and can reduce and draw because transport path is long
The problem of failure rate (paperboard probability etc.) of hair rises.
Equally, control unit not only can individually control feeding-in roll pair 106, feeding-in roll 100 can also individually be controlled, to reality
Existing said effect.
In addition, according to Fig. 6~Fig. 9 and above-mentioned discussion it is found that as the second transport path middle paper feeding track 104 and
Lower paper feeding track 105 includes a part for usual transport path 102, also, as the middle paper feeding track 104 of the second transport path
And lower paper feeding track 105 includes the load paper region 127,128 (with reference to Fig. 6) of paper sheet cassette, it should be noted that load paper region 127,
128 refer to the interior zone of paper sheet cassette (i.e. the first paper sheet cassette 123 and the second paper sheet cassette 124), is for loading paper
, in the present embodiment, the composition of paper feeding track 104 and lower paper feeding track 105 as in of load paper region 127,128 is wanted
Element participates in conveyance paper.However, being not limited to the load that middle paper feeding track 104 and lower paper feeding track 105 include paper sheet cassette
Paper region 127,128, middle paper feeding track 104 and lower paper feeding track 105 as the second transport path can not also include to supply
The load paper region 127,128 of paper carton.
In addition, here, for as the butterfly 109 of switching part, this design is described in detail.In paper in
Paper feeding track 104 or lower paper feeding track 105 are transported to middle paper feeding track 104 or lower paper feeding track 105 and usual transport path
When 102 intersection's (at butterfly 109), the butterfly 109 rotate and make paper normal through.When paper is via paper feeding
When roller pair 108 is returned, in preventing paper from returning among paper feeding track 104 or lower paper feeding track 105, makes it into and usually remove
It send in path 102.
It should be noted that its set-up mode can be changed for the butterfly 109 as switching part, so that image forms dress
Setting 10 has new function.Specifically, making image forming apparatus 10 for the thin and thick of paper and transporting pattern and thickness with thin paper
Paper transports pattern, as shown in figure 11, butterfly 109 is spun upside down setting and becomes and transports pattern and thickness according to thin paper
Paper transports pattern to switch the switching part of transport path.Pattern is transported for thin paper, the second transport path has thin paper carrying channel
Diameter, the thin paper transport path include usual transport path 102；Pattern is transported for ground paper, the second transport path is removed with ground paper
Path is sent, which includes the load paper region of paper sheet cassette.It is thin paper conveyance pattern that control unit, which is based on conveyance pattern,
Or ground paper conveyance pattern is opened and closed to control switching part, and controls the operation that conveying unit implements conveyance paper.
For example, when the paper transported is thin paper, the suppleness of paper is preferable, so even having passed through zig zag
Also there is no problem for transport path, and for this paper mold, control unit control butterfly 109 slightly rotates and selects thin paper carrying channel
Diameter, even if paper is directly entered usual transport path 102, thus, it is possible to shorten the conveyance time.For example, in the second transport path
In, for the preferable thin paper of suppleness, either use 30 ° or 65 °, in other words, paper feeding track 104 in either using
Or lower paper feeding track 105 is used, thin paper transport path can be selected come defeated by controlling butterfly 109 and slightly rotating
Send thin paper.
And when the paper transported is ground paper, the suppleness of paper is poor, therefore preferably passes through the carrying channel of slow turning
Diameter, if ground paper has passed through the transport path of zig zag, paper will collide with the turning of transport path,
Or the friction of strength occurs, this will be likely to result in, and paper is impaired, and for this paper mold, control unit controls butterfly
109 significantly rotate and select ground paper transport path, even if paper is introduced into the load paper region of paper sheet cassette, thus, it is possible to realize
Lossless conveyance.For example, in the second transport path, for the ground paper that suppleness is poor, paper is impaired in order to prevent, it is preferred to use
65 °, in other words, it is preferable that using lower paper feeding track 105, and select ground paper by controlling butterfly 109 and significantly rotating
Transport path conveys ground paper.
