Detailed description of the invention
Below, with reference to accompanying drawing, illustrative embodiment of the present invention is described in detail.
(1. the 1st illustrative embodiment)
［ structure of 1-1. medium separating and discharging mechanism ］
First, the 1st illustrative embodiment is described.Medium separating and discharging mechanism 1 is in the past shown in fig. 19 a, the medium separating and discharging mechanism 100 in the 1st illustrative embodiment is shown in fig. 19b.About medium separating and discharging mechanism 100, compared with medium separating and discharging mechanism 1 in the past, although side guides 10 is replaced by side guides 110, other structures are identical.
The length L11 of the transport direction of the side guides 110 and length W11 of Width is shorter than the length L1 of the transport direction of the side guides 10 and length W1 of Width.
Specifically, the length L11 of the transport direction of the side guides 110 and length W11 of Width determines as following.
As shown in figure 20, by build up in side guides 110 accumulation region 111, the transport direction of longer in the direction of the width rectangular medium P, Width and cornerwise length is set as length PW, PH and PD respectively.
In addition, angle θ a will be set as relative to the skew angle of Width: 1 pair of diagonal angle of medium P abuts with the side of side guides 110 respectively under the following state of medium P, and medium P angle abuts with the back side 110a of side guides 110 and cannot be crooked further, and namely medium P there occurs crooked to greatest extent in accumulation region 111.
Further, by the position abutted with the back side 110a of side guides 110 from medium P to being set as length W12 in the side of side guides 110 from the side away from this position, length W13 is set as by deducting the value that length W12 obtains from length W11.
In this case, the angle formed about medium P and back side 110a and θ a, the relation of following formula (1) is set up.
θa＝θb-θc···（1）
Further, θ b is the angle consisted of the diagonal line at angle that abuts with back side 110a and back side 110a of medium P, and θ c is the angle that the diagonal line of medium P and long limit are formed.
In addition, about θ c, the relation of following formula (2) ~ formula (5) is set up.
tanθc＝PH/PW···（2）
θc＝tan -1（PH/PW）···（3）
sinθc＝PH/PD···（4）
PD＝PH/sinθc···（5）
If formula (3) is substituted into formula (5), be then expressed as
PD＝PH/sin{tan -1(PH/PW)}···（6）
And then about θ b, the relation of following formula (7) and formula (8) is set up.
sinθb＝L11/PD···（7）
θb＝sin -1（L11/PD）···（8）
Further, if formula (6) is substituted into formula (8), be then expressed as
θb＝sin -1{L11÷{PH/{sin{tan -1(PH/PW)}}}}···（9）
＝sin -1{L11×{sin{tan -1(PH/PW)}}÷PH}···（10）
Therefore, θ a adopts formula (1), formula (3) and formula (10) to be expressed as
θa＝sin -1{L11×{sin{tan -1(PH/PW)}}÷PH}-tan -1（PH/PW）···（11）
On the other hand, about θ a, the relation of formula (12) ~ formula (15) is set up.
cosθa＝W12/PW···（12）
W12＝PW×cosθa···（13）
sinθa＝W13/PH···（14）
W13＝PH×sinθa···（15）
Because the length W11 of the Width of side guides 110 is expressed as,
W11＝W12＋W13···（16）
Therefore, if formula (13) and formula (15) are substituted into formula (16), be then expressed as
W11＝PW×cosθa＋PH×sinθa···（17）
In addition, about θ b, the relation of formula (18) and formula (19) is set up.
sinθb＝L11/PD···（18）
L11＝PD×cosθb···（19）
If formula (1) is substituted into formula (19), be then expressed as
