embodiment 2 〉
In above-mentioned embodiment 1, following structure is illustrated: utilize cam 71 that guide member 293 is moved and be located, thereby realized taking into account the inhibition of knocking sonud and suitable carrying with paper at retreating position and guide position.In the present embodiment, thus suppress knocking sonud and realize that the suitable structure of carrying with paper describes utilizing elastomeric element to absorb the bump of kowtowing when hitting guide member 293 with paper.
In addition, for fear of the repetition of explanation, the inscape identical with embodiment 1 given same numeral and omitted explanation.
Fig. 7, Fig. 8, Fig. 9 are the figure of summary structure that the conveying road 29 of present embodiment is shown, Fig. 7 is illustrated in and is formed with crooked state from paper supply carton 21 paper supplies with paper, state when the bending that Fig. 8 illustrates Fig. 7 is eliminated, Fig. 9 illustrate front end and guide member 293 state of contact with paper from manual paper feeding plate 25 paper supplies.
One side's of compression spring 81 (first elastomeric element) end be linked to guide member 293 with the faces of carrying road 29 opposition sides, the opposing party's of compression spring 81 end is fixed in the fixed partss such as framework 82 of chopping machine 100 main bodys.
In addition, in Fig. 8 and Fig. 9, be shown in broken lines the guide member 293 among Fig. 7 and the position of compression spring 81.
When from the shown in Figure 7 state that is being formed with paper after crooked status transition to bending shown in Figure 8 is eliminated, guide member 293 is from bearing the thrust towards the interior side direction of bending with paper.And then by this thrust, compression spring 81 is compressed, and guide member 293 shakes towards the interior side direction of bending, thereby moves to retreating position shown in Figure 8.At this moment, because above-mentioned thrust is absorbed by compression spring 81, therefore, kowtow the power of hitting guide member 293 with paper and weakened, the result can suppress knocking sonud.And then after deviating from from carton delivery section 220 (holding part of outlet roller 22 and separate roller 26) with the paper rear end, above-mentioned thrust disappears, and by the elastic force of compression spring 81, guide member 293 turns back to position shown in Figure 7.
With paper by under the situation of manual paper feeding plate 25 paper supplies, when be admitted to from manual paper feeding delivery section 270 carry in the road 29 with paper S by when timing roller is carried 24, as shown in Figure 9, use the front end of paper S to contact with guide member 293.At this moment, because stiffness with paper S, guide member 293 bears thrust towards the interior side direction of bending from the front end with paper S, the result, compression spring 81 compressions, but, the thrust of this moment is the instantaneous thrust littler than the thrust under the situation shown in Figure 8, with the front end of paper S just with after guide member 293 contact, promptly on the surface of guide member 293 to towards timing roller to 24 direction slip, above-mentioned thrust weakens sharp, thereby compression spring 81 is little in the displacement of compression direction, therefore, the displacement towards the curved interior direction of guide member 293 is also little, can not hinder 293 pairs of guide members with paper S towards timing roller to 24 suitable guiding.
And, thereby begin to slide above-mentioned thrust when weakening sharp when front end on the surface of guide member 293 with paper S, by the elastic force of compression spring 81, guide member 293 is pushed to be got back among Fig. 9 with the position shown in the dotted line.Thus, pushed back towards the interior side direction of carrying the road (crooked lateral direction) with the fore-end of paper S, with paper S by more reliably towards timing roller to 24 guiding.And, use spring as compression spring 81 with following elasticity modulus: the amount of compression of this compression spring 81 when above-mentioned front end with paper S contacts with guide member 293 can not hinder usefulness paper S towards timing roller to 24 the conveying that suits.
Further, consider if guide member 293 can be towards more keeping out of the way to a certain degree by crooked interior side direction than guide position shown in Figure 7, thereby the thrust of the paper that then can absorb to use by oneself suppresses knocking sonud to a certain extent, therefore, for the elasticity modulus of compression spring 81, being not limited to when crooked the elimination as shown in Figure 8, guide member 293 retreats into the elasticity modulus that is the position of straight condition with paper S.
As described above like that, according to the structure of present embodiment, can use compression spring 81 to realize taking into account the inhibition of knocking sonud and suitable carrying with paper.And, owing to do not use, therefore can suppress to guide the action sound of motor 72 and consume electric power as the propulsion source that guides motor 72, and, because replacement guiding motor 72 and cam 71 use cheap compression spring 81, therefore help the cost reduction.
<embodiment 3 〉
In above-mentioned embodiment 1 and 2, to up to timing roller 24 carton being carried the road, constituted the structure that the guide surface single-piece guide member 293 of crooked inboard moves to retreating position and be illustrated from carton delivery section 220.But existing not is the whole situation about contacting with paper S during with crooked elimination of the guide surface of inboard of above-mentioned bending yet, movablely can suppress knocking sonud even if only make to become with the part that contacts with paper S yet.In the present embodiment, become movable to the part of the guide member of the inboard that makes above-mentioned bending and realize taking into account the inhibition of knocking sonud and the suitable structure of carrying with paper describes.

And, thereby begin to slide above-mentioned thrust when weakening sharp when front end on the surface of guide member 296 with paper S, by the elastic force of compression spring 81, guide member 296 is pushed to be got back among Figure 12 with the position shown in the dotted line.Thus, pushed back towards the interior side direction of carrying the road (crooked lateral direction) with the fore-end of paper S, with paper S by more reliably towards timing roller to 24 guiding.And compression spring 81 uses the spring with following elasticity modulus: the amount of compression of this compression spring 81 when above-mentioned front end with paper S contacts with guide member 296 can not hinder usefulness paper S towards timing roller to 24 the conveying that suits.
Further, consider if guide member 296 can be towards more keeping out of the way to a certain degree by crooked interior side direction than guide position shown in Figure 10, thereby the thrust of the paper S that then can absorb to use by oneself suppresses knocking sonud to a certain extent, therefore, for the elasticity modulus of compression spring 81, being not limited to when crooked the elimination as shown in figure 11, guide member 296 retreats into the elasticity modulus that is the position of straight condition with paper S.
As described above like that, according to the structure of present embodiment, can use compression spring 81 to realize taking into account the inhibition of knocking sonud and suitable carrying with paper.And, same with embodiment 2, owing to do not use as the propulsion source that guides motor 72, therefore can suppress to guide the action sound of motor 72 and consume electric power, and,, therefore help cost to reduce owing to replace guiding motor 72 and cam 71 to use cheap compression spring 81.Further, in the present embodiment, it is movable only making when eliminating with the bending of paper S the guide member of the part that contacts with sweep with paper S, thus, can dwindle the space of the displacement that is used to allow guide member 296, the result helps the miniaturization and of device.
