(structure of recording paper dish 50)
Then describe the structure of recording paper dish 50 in detail.As shown in Figures 1 and 2, recording paper dish 50 has: as the disc main body 60 of an example of main body, as the pair of engage members 70 of the example of support component and support component A.Shown in Fig. 2 (A), the pair of rotary shafts 61 that each strutting piece 70 can be provided with disc main body 60 left and right directions two ends is that the center rotates respectively.Shown in Fig. 1, Fig. 2 (A), strutting piece 70 can to side-prominent use location, direction of transfer (paper feeding direction) upstream one of recording paper 3, and Fig. 2 (B) shown in variable condition between collecting position overlapping on the disc main body 60.
Further, disc main body 60 can load and unload and be arranged on swingably on the loam cake 2, be configured under the state of collecting position at each strutting piece 70, by resembling shown in Fig. 2 (C), close, thereby play a role as the lid that covers paper insertion mouth 6, recording paper exit roller 15, original copy insertion mouthful 26 (with reference to Fig. 1).Therefore, under the situation that disc main body 60 plays a role as lid, can suppress dust well and enter near paper insertion mouth 6, recording paper exit roller 15, the original copy insertion mouth 26.And when not using disc main body 60, disc main body 60 is deformed into closes original copy and inserts mouthfuls 26 under strutting piece 70 is configured in the state of described collecting position, thereby can make disc main body 60 densifications.That is, can make picture unit 1 densification on the whole.
Fig. 3 is the perspective view that expression strutting piece 70 is installed to the mounting structure of disc main body 60, the back side one side of surface one side of Fig. 3 (A) indicating panel main body 60 (placed side one side of recording paper 3), Fig. 3 (B) expression strutting piece 70, surface one side of Fig. 3 (C) expression strutting piece 70.In addition, the upside among Fig. 3 (A) is direction of transfer upstream one side (below be also referred to as front end one side) of recording paper 3.And, only represented the left part of disc main body 60 and the structure of left side strutting piece 70 among Fig. 3, the right side is same structure except left-right symmetric.
Shown in Fig. 3 (A), rotating shaft 61 is from the surface of disc main body 60 to be given prominence to and integrally formed cylindricly.The part of rotating shaft 61 is by adding otch at the direction of principal axis of rotating shaft 61, and becomes the 61A of spring portion of the elastically deformable that makes progress in the footpath of rotating shaft 61.The front end of the 61A of spring portion forms to the outstanding hook portion 61B of peripheral direction.
Corresponding with it, shown in Fig. 3 (B), the hole portion 71 that rotating shaft 61 can insert circle wherein is set on the strutting piece 70, form near the internal face of hole portion 71 and can suppress the thickness that strutting piece 70 relative rotation axis 61 tilt.And shown in Fig. 3 (C), on the surface of strutting piece 70, the slot part 72 of accepting hook portion 61B links to each other with hole portion 71 and forms.Therefore, when making the 61A of spring portion strain rotating shaft 61 is inserted into hole portion 71, then hook portion 61B can be chimeric with slot part 72.
Further, shown in Fig. 3 (A), (B), the surface of disc main body 60 forms cam 63, and the back side of strutting piece 70 forms cam 73.Cam the 63, the 73rd, an example of moving range limiting part, when strutting piece 70 is configured in the use location toward each other.Therefore, make strutting piece 70 from collecting position shown in Fig. 4 (A) when move the use location shown in Fig. 4 (B), cam 73 is stepped up cam 63, with strutting piece 70 to surface direction pushing and rise.At this moment, hook portion 61B and slot part 72 are chimeric, and so, strutting piece 70 is positioned at the front end of rotating shaft 61, and can suppress rotating shaft 61 and give prominence to and the transmission of obstruction recording paper 3 from the surface of strutting piece 70.In addition, as Fig. 3 (A) (B) shown in, processed curved chamfering 63A, 73A (R) in the cam 63 and 73, make cam 63 be easy to step up cam 73.
And, as shown in Figure 3, Figure 4, in front end one side of disc main body 60, the retainer 65 of an integrally formed example as the 1st rotation restricting unit and moving range restriction accessory.Retainer 65 has: the 65A of platform portion, and one side supported configurations is at the strutting piece 70 of use location from the back side; Protuberance 65B, outstanding from the 65A of this, when strutting piece 70 is configured in the use location, chimeric with the recess 75 at the back side that is arranged on this strutting piece 70; Protuberance 65C when strutting piece 70 is configured in the use location, cooperates with the end edge of this strutting piece 70.Further, in the integrally formed plate spring part 77 in end near hole portion 71 1 sides of strutting piece 70.Plate spring part 77 is examples of the 2nd rotation restricting unit, when strutting piece 70 is configured in collecting position, cooperates with the rib 67 of disc main body 60, can remove this cooperation by strain.
Therefore, when strutting piece 70 is configured in collecting position, shown in Fig. 4 (A), cooperate with rib 67 by plate spring part 77, can suppress strutting piece 70 because deadweight etc. moves from regular collecting position.For example, open loam cake 2 replacing China inks from state shown in Fig. 2 (C) and be with the situation that exists disc main body 60 shown in Fig. 2 (B), to open at 11 o'clock owing to deadweight.Shown in Fig. 2 (A), move to the use location even also can suppress strutting piece 70 in this case like that.
And when strutting piece 70 was configured in collecting position, shown in Fig. 4 (A), cam 63,73 was no longer relative each other, and strutting piece 70 can move on the direction of principal axis of rotating shaft 61.Therefore, as described below, can be with two strutting pieces, the 70 overlapping surfaces that are housed in disc main body 60.Fig. 5 (A) is the vertical view of the recording paper dish 50 of the overlapping state of accommodating strutting piece 70 of expression, and Fig. 5 (B) is its B-B line sectional view, and Fig. 5 (C) is its C-C line sectional view.And Fig. 5 (D) is the enlarged drawing of the D part of Fig. 5 (C), and Fig. 5 (E) is the enlarged drawing of the E part of Fig. 5 (C).Shown in Fig. 5 (D), the strutting piece 70 that is configured in collecting position described direction of principal axis movably distance A greater than the thickness B of strutting piece 70.Therefore,, make another strutting piece 70 be configured in the chimeric position of hook portion 61B and slot part 72, then can be as Fig. 5 (A)～(C) overlappingly accommodate two strutting pieces 70 if a strutting piece 70 is contacted with disc main body 60 surface as Fig. 5 (E).
On the other hand, when strutting piece 70 is configured in the use location, remove the cooperation of plate spring part 77 and rib 67 by rotary support member 70.And by being further rotated strutting piece 70, the protuberance 65C butt of the end edge of strutting piece 70 and retainer 65 therefore can be with strutting piece 70 correctly, easily be configured on the use location.And at this moment, the protuberance 65B of retainer 65 and the recess 75 of strutting piece 70 are chimeric, therefore can suppress strutting piece 70 and move from regular use location because of deadweight waits.In addition, at strutting piece 70 from collecting position to the use location rotation midway, two strutting pieces 70 of overlap condition are to nonoverlapping state exchange.
Further, at this moment, one side supports strutting piece 70 from the back side by the 65A of platform portion.The height of the height of the 65A of this and cam 63,73 and about equally, by by the 65A of platform portion strutting piece 70 being supported, the strutting piece 70 that can further suppress to be configured in the use location well tilts.
And the protuberance 65C of retainer 65 has the more outstanding height in surface than the strutting piece 70 that is configured in the use location.Therefore, can be by end edge to the Width (direction vertical) of the side-prominent 65C leader record paper 3 in the surface one of strutting piece 70 with the direction of transfer of recording paper 3.
(effect of present embodiment)
As mentioned above, in the present embodiment, when strutting piece 70 is configured in the use location, cam 63,73 is relative, and when strutting piece 70 was configured in collecting position, cam 63,73 was not relative, by this simple structure, can only make strutting piece 70 removable on described direction of principal axis at collecting position.Therefore, need not the application of force of spring etc., simplify the structure and accommodate or use the operation of strutting piece 70 also to become easy.Further, make strutting piece 70 when collecting position moves, utilize the pressure under the situation of spring need not be applied to strutting piece 70, can suppress to constitute the situation of the resin albefaction of strutting piece 70 well.
