As shown in Figure 1, in the chopping machine 11 of present embodiment, be equipped with automatic paper feeding device 13 as feedway in the rear side of main body 12, this automatic paper feeding device 13 is used to supply the paper P as recording medium.Paper guide 17 as mounting portion is installed on automatic paper feeding device 13, and this paper guide 17 has paper supply tray 14, hopper 15 and edge guide member 16.In addition, automatic paper feeding device 13 has and is supplied to paper supply driver train (omitting diagram) in the main body 12 one by one be positioned in paper P on the paper guide 17 with stacked state.
In main body 12, be provided with carriage 18 at main scanning direction (left and right directions among Fig. 1) reciprocating action, and, header record 19 had as recording portion in the bottom of carriage 18.Printing to paper P is undertaken by alternately repeating following action: promptly, make carriage 18 spray the operation of recording of ink from header record 19 towards paper P in the process that main scanning direction moves; And with the paper feeding action of paper P towards the computed carrier amount of sub scanning direction (the place ahead to) conveyance regulation.Paper P after the printing is discharged from from the ejection port 20 in the front side of main body 12 lower openings.
Below, in conjunction with Fig. 2 automatic paper feeding device 13 is described.
As shown in Figure 2, be bearing in the rear side of base portion 21 with the lower end side of the paper supply tray 14 of the skewed back side portion that is configured in main body 12, and, near the upper face side of paper supply tray 14 and central authorities, be provided with hopper 15 at left and right directions.And, between the lower end side of hopper 15 and paper supply tray 14, clamped compression spring 22.It can be that move between paper supply position shown in Figure 2 and retreating position (with reference to Fig. 3) at the center with an axle 15a who is located at upper end side that hopper 15 constitutes, thereby this retreating position is to compare compression spring 22 to be compressed the lower end side that makes hopper 15 towards position that anticlockwise direction moves with state shown in Figure 2.
It can be the state that the center rotates with S. A. 24 that near the lower end of the hopper 15 that is positioned at the paper supply position the place ahead, side observe that the paper feed roller as output block (conveying roller) 23 roughly be the D word shape is configured to.Paper feed roller 23 has matrix part 23a and bearing surface and forms parts 25, and described matrix part 23a is formed by the resin material with rigidity etc., and described bearing surface forms parts 25 and formed by rubber-like rubber, and the outer circumferential side of covering matrix part 23a.And the bearing surface of paper feed roller 23 forms parts 25 with following outer peripheral face that forms paper feed roller 23: is the periphery 25a as bearing surface of radius with the axle center C of distance S. A. 24 apart from r1; And apart from the axle center C of S. A. 24 apart from r2 (r2＜as the on-circular face r1) than the short tabular surface 25b of distance of periphery 25a apart from the axle center C of S. A. 24.And then paper feed roller 23 is accompanied by the rotation driving of S. A. 24 and rotates, and carries out the paper supply action (carrying action) of paper P thus.
And, in the following manner the axle center C of setpoint distance S. A. 24 apart from r1, r2: be configured at hopper 15 under the state of paper supply position, when paper feed roller 23 rotations, tabular surface 25b not with paper P butt, but periphery 25a and paper P butt, further paper P is compressed the application force of spring 22 and is urged on periphery 25a.And then, under the state of periphery 25a and paper P butt, when paper feed roller 23 rotation and the friction force that produces between the paper P be configured to bigger than the friction force that produces each other at stacked paper P.Therefore, if the periphery 25a that become bearing surface of paper feed roller 23 in formed the outer peripheral face that parts 25 form by bearing surface is connected to the state rotation on the paper P, then the application force of compression spring 22 becomes vertical resistance, and the friction force that produces between periphery 25a and paper P becomes conveyance power, thereby paper P is exported.
In base portion 21, the position in the downstream of the hopper 15 that is configured in the paper supply position with being positioned on the conveyance direction of the paper P shown in the arrow in Fig. 2 is equipped with separating component 29.Be formed with dip plane 29a on separating component 29, the paper P that exports from paper supply tray 14 can collide with predetermined angular with this dip plane 29a.That is, dip plane 29a fixed configurations in Fig. 2 with the downstream of the paper guide 17 on the throughput direction of the paper P shown in the arrow.And, in base portion 21, be formed with the guide portion 21a that below the front side, extends obliquely in the more front side of separating component 29.
Separating component 29 with the central authorities of the tabular surface 25b of paper feed roller 23 near do not form parts 25 under the opposed situation and contact with the bearing surface of the outer peripheral face that forms paper feed roller 23, but with the opposed situation of periphery 25a under with bearing surface formation parts 25 butts of the outer peripheral face of formation paper feed roller 23.And then, under the situation that forms the periphery 25a butt in the outer peripheral face that parts 25 form by bearing surface of separating component 29 and paper feed roller 23, bearing surface forms parts 25 to form the mode elastic deformation of the degree of parts 25 stack 0.5mm with bearing surface, and the part of the stack of separating component 29 is born the elastic restoring force that bearing surface forms parts 25.
And when conveyance of sheets P, after the right-hand revolution and periphery 25a and separating component 29 butts as bearing surface of paper feed roller 23 in Fig. 2, hopper 15 moves to the paper supply position from retreating position.And then, if paper P is output by the paper feed roller 23 that is further rotated, the dip plane 29a of the front end of then uppermost paper P and separating component 29 collision.
And then, while thereby the uppermost paper P after front end and the dip plane 29a collision pushes forming periphery 25a that parts 25 form by bearing surface and making bearing surface form parts 25 elastic deformations and overcome elastic restoring force that bearing surface forms parts 25 and form the gap be transferred between periphery 25a and separating component 29 of paper feed roller 23.That is, set the collision angle of separating component 29 and uppermost paper P and elasticity that bearing surface forms parts 25 and bounce-back property in the mode that only between periphery 25a and separating component 29, forms the gap that to pass through for uppermost paper P by pressing force by the uppermost paper P of paper feed roller 23 output.
In addition, when paper feed roller 23 was exported uppermost paper P, the paper P of its lower floor also moved towards throughput direction together because of the friction force that produces each other at paper P sometimes.In this case, bear the elastic restoring force that bearing surface forms parts 25 with the paper P of the lower floor of the dip plane 29a of separating component 29 collision via uppermost paper P, do not overcome the conveyance power that this elastic restoring force enters the degree between periphery 25a and the separating component 29 but do not have.Therefore, even under the situation that the paper P of lower floor is pulled by the uppermost paper P by paper feed roller 23 outputs because of friction force, the paper P of lower floor is prevented from its conveying of stage that the dip plane 29a with separating component 29 collides, thereby separates with uppermost paper P.
Below, according to Fig. 3～Fig. 5 the effect of the automatic paper feeding device 13 of formation is in the above described manner described.
For paper feed roller 23, opposed near the central authorities of tabular surface 25b at reset position shown in Figure 3 with separating component 29, and hopper 15 is configured in the retreating position that leaves from paper feed roller 23.
And then, if thereby S. A. 24 begins to rotate and drives the right-hand revolution of paper feed roller 23 in Fig. 3, and then form the periphery 25a that parts 25 form and be connected on the separating component 29 by the bearing surface of paper feed roller 23.Then, hopper 15 moves to the paper supply position from retreating position, and uppermost paper P is connected on the periphery 25a of paper feed roller 23.
If paper feed roller 23 is further rotated, then collide by the front end of the uppermost paper P of paper feed roller 23 output dip plane 29a with separating component 29.And then, thereby make bearing surface form parts 25 elastic deformations by the periphery 25a that pushes paper feed roller 23, thus, periphery 25a and separating component 29 between form gap on one side, the front end that makes uppermost paper P on one side is by separating component 29.At this moment, though the friction force that the paper P of lower floor also produces at paper P each other with uppermost paper P one cause and being output, but the paper P of lower floor is prevented from its conveying of stage that the dip plane 29a with separating component 29 collides, and separates with uppermost paper P as shown in Figure 4.
And then, be accompanied by the rotation of paper feed roller 23, pass through separating component 29 while only uppermost as shown in Figure 5 paper P makes bearing surface form parts 25 elastic deformations, thereby be transported to header record 19 sides.
First embodiment according to the above description can access following effect.
(1) by the uppermost paper P of the dip plane 29a of paper feed roller 23 outputs and front end and separating component 29 collision, its periphery 25a that pushes paper feed roller 23 on one side makes bearing surface form parts 25 elastic deformations, and overcome elastic restoring force that bearing surface forms parts 25 and between periphery 25a and separating component 29, form the gap that only uppermost paper P can pass through and be transferred on one side, carry out the separating of paper P of uppermost paper P and its lower floor thus, can prevent overlapping conveying.And then therefore the configuration because separating component 29 is fixed can keep the collision angle of paper P and dip plane 29a constant.Therefore, can prevent the overlapping conveying of paper P accurately.

(second embodiment)
Below, according to Fig. 6 second embodiment of the ink-jet printer that liquid injection apparatus of the present invention is embodied as serial mode is described.
Present embodiment is identical with first embodiment at following point: promptly, in the automatic paper feeding device 13 that the chopping machine 11 as recording device is possessed, paper feed roller 23 is cooperated with separating component 29 and is carried out separating of paper P, but, the guide reel 23 of present embodiment has via the spring members of sliding part to bearing surface formation parts 25 application of forces, and this point is different with first embodiment.
Below, be that the center describes with the point different with first embodiment.
As shown in Figure 6, the inside of the matrix part 23a in paper feed roller 23, S. A. 24 and bearing surface form between the parts 25 and when carrying out the separation of paper P and the part of separating component 29 butts be formed with reception hole 23b.And then, in reception hole 23b, take in and be configured in the spring members 36 that bearing surface forms the sliding part 35 of parts 25 sides and is configured in S. A. 24 sides.Sliding part 35 can move with the direction of leaving S. A. 24 towards approaching in reception hole 23b, and, often be bearing surface and form the end of parts 25 sides and the state that bearing surface forms parts 25 butts.And then under the part of taking in sliding part 35 of paper feed roller 23 was configured in situation with separating component 29 opposed positions, spring members 36 was compressed, and 36 pairs of bearing surfaces of spring members form parts 25 towards the direction application of force near separating component 29.
Below, the effect of the automatic paper feeding device 13 of formation is in the above described manner described.
For paper feed roller 23, when beginning rotation, S. A. 24 drives, when the Zhou Fangxiang in the outer peripheral face of bearing surface formation parts 25 and cooresponding part of reception hole 23b (being the part of taking in sliding part 35 in the paper feed roller 23) and separating component 29 butts, bearing surface forms parts 25 separated parts 29 and pushes and elastic deformation.So sliding part 35 moves towards the direction near S. A. 24, spring members 36 is compressed.At this moment, bearing surface forms parts 25 bear spring members 36 via sliding part 35 application force.
If paper feed roller 23 is further rotated, then collide by the front end of the uppermost paper P of paper feed roller 23 output dip plane 29a with separating component 29.And then uppermost paper P pushes the periphery 25a of paper feed roller 23, and the application force that overcomes spring members 36 makes bearing surface form parts 25 elastic deformations.And then bearing surface forms the elastic restoring force of parts 25 and the application force of spring members 36 forms the gap between periphery 25a and separating component 29 Yi Bian overcome, Yi Bian by separating component 29.At this moment, though the friction force that the paper P of lower floor also produces at paper P each other with uppermost paper P one cause and being output, but the paper P of lower floor is prevented from its conveying of stage that the dip plane 29a with separating component 29 collides, thereby separates with uppermost paper P.
And then, if being accompanied by the rotation of paper feed roller 23 takes in the part of sliding part 35 and leaves from separating component 29 on Zhou Fangxiang, after this uppermost paper P passes through separating component 29 while the elastic restoring force of bearing bearing surface formation parts 25, and is transported to header record 19 sides.And, in this case,, bearing surface is connected on the matrix part 23a with rigidity because forming the inner peripheral surface side of parts 25, therefore keep elastic restoring force fully towards separating component 29 sides, can suppress the overlapping conveying of the paper P of lower floor.
According to above second embodiment that has illustrated, (1) in first embodiment～(3), can also obtain following effect.
(4) by bearing surface being formed parts 25 towards spring members 36 near the direction application of force of separating component 29, make bearing surface form parts 25 by with the dip plane 29a collision of separating component 29 after uppermost paper P push and during elastic deformation, can access the application force that becomes the load that is directed to the paper P that pushes periphery 25a.Therefore,, also can replenish its elastic restoring force, can prevent the overlapping conveying of paper P accurately even for example form under the situation that the hardness etc. of parts 25 changes at the inferior bearing surface of hot environment.
(5) utilize 36 pairs of bearing surfaces of spring members to form parts 25 application of forces via sliding part 35, can reliably effort be formed on the parts 25 at bearing surface.And, by utilizing spring members 36 application of forces, can suppress to be accompanied by the variation of environmental factors such as temperature and the variation that occurs, can set application force accurately.
In addition, the respective embodiments described above also can change to the embodiment of following other.
The paper supply action is not limited to the rotation realization by paper feed roller 23, for example also can be by the mobile realization of conveyance band.
Force application part is not limited to spring members, for example also can possess and have high bounce polyurethane etc.Thus, if for example between the outer peripheral face of matrix part 23a and bearing surface form the inner peripheral surface of parts 25, spread all over the cooresponding Zhou Fangxiang of periphery 25a field filled polyurethane etc., then can be to periphery 25a integral body towards the radiation direction application of force.
