(Tray for paper use main part)

As shown in Figure 1, Tray for paper use 10 is a kind of cap 40 to be installed in structure on the Tray for paper use main part 12 (below be also referred to as main part 12) removably.And, in the main part 12,, be formed with and continue to use the rib 20b that paper carrying direction is extended in upper surface side with paper trucking department 20, utilize the upper surface of rib 20b to accept the paper of using that is handled upside down.In addition, as shown in Figure 1, a part is carried out the local holding element 50 that keeps with paper be installed in removably on the Tray for paper use main part 12.As shown in Figure 4, this with paper trucking department 20 with the both sides of paper carrying direction (specifically, both sides (transverse ends side) when the direction conduct vertical with carry direction with paper of using paper trucking department 20 is horizontal), be provided with respect to the side wall portion of generally perpendicularly holding up with the Width of paper trucking department 20 22,22.Main part 12 constitutes with the shape of paper Width as length direction, distolateral with paper carrying direction downstream, form a pair of installation that is used to be installed on the paper feeding mechanism 100 and uses engagement section 28,28.Install with forming on the engagement section 28 at each and to install with engaging pawl 28a, as shown in Figure 3, engage with the portion that is stuck 7 on being arranged on paper feeding mechanism 100 with engaging pawl 28a by this installations, Tray for paper use 10 and paper feeding mechanism 100 are fixed.

(ways)

And as shown in Figure 4, being provided with at main part 12 can be around a pair of

ways

30,30 of turning cylinder (with the symbol R1 represent) rotation vertical with carry direction (D1 represents with symbol) with paper.Here, with the turning cylinder of ways 30, set for with the paper Width promptly the length direction of this Tray for paper use 10 as axial.This

ways

30,30 is at Width (length direction) side end with paper trucking department 20, disposes in abutting connection with ground with the inboard of side wall portion 22,22.By this structure,

ways

30,30 stably can be located on the paper Width.And,

ways

30,30, between with the two

side portion

22,22 of paper trucking department 20 to the guiding position of leading (with reference to Fig. 6, then chat) with can not carry out set positions to dodging on the position (with reference to Fig. 7, then chat) of leading with paper with paper.The Tray for paper use 10 of this example, by the set positions of this

ways

30,30, can carry out with 2 kinds with the cooresponding width setup of paper.Like this, a side the plate face that constitutes

tabular ways

30,30 is by the supporting of the medial surface of side wall portion, and the opposing party's plate leads in the face of the lateral margin with paper of carrying, thereby for paper size, can tackle the small difference of thickness of slab degree.

Specifically, in this example, Tray for paper use 10 can be tackled these 2 kinds of sizes of letter size that A4 size that width is 210.0mm and width are 215.9mm.Tray for paper use 10 is at both sides'

ways

30,30 and can utilizes the mail size when dodging the position, and both sides'

ways

30,30 can utilize the A4 size when being in the guiding position.That is, the interval of inner face 22c, the 22c of two

side wall portions

22,22 becomes the size roughly the same with the width of letter size, and as shown in Figure 4, the width that is in the

ways

30,30 of guiding during the position becomes roughly and the measure-alike size of A4.In this example, the shape that both sides'

ways

30,30 is identical each other, the width t1 of a side ways is identical with the width t2 of the opposing party's ways.Therefore, the line of centers between the line of centers between two side wall portion 22c, the 22c and two

ways

30,30 both sides' inner face 30a, the 30a becomes same position.Fig. 4 represents its line of centers C, no matter use which kind of size, all is to use paper with carrying movably along line of centers C with the center of the Width of paper.

As Fig. 5 A, Fig. 5 B and shown in Figure 7, ways 30 is being dodged the position, the lower position that is maintained at upper surface 20a with paper trucking department 20 (specifically being arranged on the face of minute widths of the upper end of rib 20b) (promptly, dodging the position, the end of ways 30 is not outstanding from the upper surface of rib 20b).In this example, as shown in Figure 7, the maintenance by being stuck portion 26 engages with the lower end of projection 26e and the arm 30d of ways 30, and ways 30 remains on dodges the position.In addition, as shown in Figure 6, ways 30 guiding positions are provided with the stop part 32 that engages with other members (specifically being stuck portion 26).By stop part 32, ways 30 stably can be remained on the guiding position.Fig. 8 A be see from the front be in the such guiding position of Fig. 6 the time the figure of ways 30.Fig. 8 B represents the installing condition of ways 30, shown in Fig. 8 B, under the such installing condition of Fig. 8 B, on stop part 32, be provided with respect to imaginary plane F and have the tapering 32a on bevelled surface and have support 32b with respect to the upper surface 26a of rotary motion trace approximate vertical along the rotary motion trace of ways 30.

On the other hand, shown in Fig. 9 A and Fig. 9 B,, be provided with the portion that is stuck 26 that engages with the stop part 32 of ways 30, but this is stuck portion's 26 elastically deformables, to become the non-fastening state that does not engage with stop part 32 with paper trucking department 20.Specifically, shown in Fig. 9 A and Fig. 9 B, be stuck portion 26 and form and roughly continue to use cantilever-shaped that paper carrying direction extends, by operating free end 26c side, can be towards Width deflection with the paper trucking department.In addition, shown in Fig. 9 A and Fig. 9 B, be stuck the lower position that portion 26 is configured in the upper surface (the upper surface 20a of rib 20b specifically) of using paper trucking department 20, and, can make the operation of elastic deformation from the dorsal part of this usefulness paper trucking department 20.According to this structure, when supplying with the paper carrying or with paper, being stuck portion 26 can not become obstacle, is stuck portion 26 and is difficult for by maloperation.For operation from dorsal part, no matter operate any part can, but, then carry out deflection easily and operate if the maintenance of the bottom that is arranged on the portion of being stuck 26 is operated with projection 26e.That is, can be by the fastening state of easy arrangement uncouples ways 30.

Be stuck portion 26 in the guiding position shown in Fig. 8 B, engage, so that ways 30 is limited (that is, be constrained to ways 30 is rotated towards the below) to the displacement of dodging the position with ways 30.On the other hand, shown in Fig. 8 C, the operator removes engaging by being stuck portion's deflection, then allows ways 30 to dodging position displacement (that is, ways 30 rotates from the state of Fig. 8 C) downwards.Ways 30 is removed the condition that is operating as with the operator to the engaging that is stuck portion 26, can carry out displacement to the position of dodging shown in Figure 7 from the guiding position shown in side's side of Fig. 6, and, can carry out displacement for the operation of ways 30 according to the operator from dodging location guide when displacement is carried out in the position.That is, ways 30 is in guiding during the position, as not carrying out operation is removed in the engaging that is stuck portion 26, and ways 30 can be to not dodging position displacement, so can not become the structure that is suitable for stable maintenance because of impacting or maloperation causes that ways comes off.On the other hand, from dodging location guide when the position displacement, as long as this ways 30 is operated just movable, displacement easily.

That is, on ways 30, the tapering that has the bevelled surface with respect to the imaginary plane F along the rotary motion trace of this ways 30 is set, being stuck portion 26 can be towards the direction displacement that intersects with imaginary plane F.In this example, to be the center with support 25 rotate around support 25 ways 30, so can set axially (Width of usefulness paper trucking department promptly) the vertical imaginary plane F with support 25.And in Fig. 8 B, C, for the position of imaginary plane F, conceptually represent with long and short dash line.

On the other hand, ways 30 from dodge location guide when the position displacement (, ways for side's side of Fig. 7, during state) from the replying state of Fig. 7 to Fig. 6, according to the rotation of ways 30, be stuck the surface below 26b and the tapering 32a butt of portion 26, and, be deformed into by this tapering 32a towards and the shape of direction (the arrow Y direction) release that intersects of imaginary plane F, cross this tapering 32a.Cross at tapering 32a under the state of the portion of being stuck 26, shown in Fig. 6 (also with reference to Fig. 8 B), be stuck portion's 26 elastic recoverys once more, be set on the clamped position that the below of ways 30 is supported by the upper surface 26a that is stuck portion 26.

In this example, as shown in Figure 6, a pair of

ways

30,30 that is same shape is separately positioned on the both side ends of using paper trucking department 20, and each ways 30 is in the guiding position, and its side is by the medial surface 22c supporting of side wall portion.Ways 30 constitutes tabular, and a side plate face 30b is by the medial surface 22c of side wall portion 22 supporting, and the plate face 30a by the opposing party leads to the lateral margin of being carried with paper trucking department 20 with paper.
