In an embodiment of the utility model, as shown in figure 3, disclosing a kind of original copy feedway 12, the original copy
Feedway 12 includes the original copy pallet 121 for placing original copy, with respect to the two sides of original copy conveying direction on original copy pallet 121, is divided
It is not provided with the side plate 122 of adjustable relative distance, one of side plate 122 is height-adjustable combined type side plate 2, is such as schemed
Shown in 4, which includes upward guide piece 21, upward guide piece 22 and spring 23, and upward guide piece 22 is the bulk of rectangle,
The sliding groove 123 for the opposite sliding of two blocks of side plates 122 is provided on original copy pallet 121, upward guide piece 22 passes through sliding groove 123
It is slidably mounted on original copy pallet 121, the shape of upward guide piece 21 is identical as the shape of upward guide piece 22, but it is opened for one end
The hollow box body of mouth, can be covered completely outside the outer surface of upward guide piece 22 by open end, and spring 23 is with respect to original copy pallet 121
It is vertically installed in upward guide piece 22, and the upper end of spring 23 can will cover on upward guide piece 22 in the state of uncompressed
Upward guide piece 21 jacked up to the direction far from upward guide piece 22, the superposition of upward guide piece 21 and upward guide piece 22 after jack-up is high
Degree is equal to the height of conventional side plate 122.
After structure using combined type side plate 2, when original copy pallet 121 conveys large-sized original copy, due to spring 23
The height of supporting role, combined type side plate 2 can be identical as the height holding of another block of side plate 122, it can be achieved that large scale original
The normal holding action of original text；It, can be in clamping process or after clamping, by group when original copy pallet 121 conveys the original copy of small size
The upward guide piece 21 of box-like side plate 2 overcomes the elastic force of spring 23 to be pressed on upward guide piece 22, the combined type side plate 2 after declining at this time
Height, will not influence can in the operating process to small size original copy to the operation of small size original copy of centre clamping
So that upward guide piece 21 is in down state always, unclamps again upward guide piece 21 after the completion.
Present embodiment passes through the combined type side plate that can change height at any time, when can keep normally conveying large scale original copy
Highly, additionally it is possible to reduce height when conveying small size original copy, to facilitate the operation to small size original copy, substantially improve original copy
The transaction capabilities of feedway.
To improve the stability of combined type side plate 2, as shown in figure 5, installation spring 23 can be arranged in upward guide piece 22
Through hole 221, as shown in fig. 6, simultaneously in upward guide piece 21 at position corresponding with spring 23 be arranged can be inserted into spring 23
Interior fixed column 211.Upward guide piece 22 can be equally hollow structure, and through hole 221 is then by hollow tubular at through hole
221 can be set two, and each through hole 221 runs through upward guide piece 22 (under i.e. in the short transverse of upward guide piece 22 respectively
Guiding piece is perpendicular on the direction of original copy pallet).After spring 23 is mounted in through hole 221, bottom end can passed through by setting
Annular convex platform in perforation 221 is stuck in through hole 221, avoids being dropped out by the lower openings of through hole 221, the upper end of spring 23
Protrude through the upper opening in hole 221.The diameter of fixed column 211 is less than the internal diameter of spring 23, therefore can be in upward guide piece 21
Be inserted into upward guide piece 22 when be directly inserted in spring 23, make 21 sets of upward guide piece on upward guide piece 22 after structure it is more stable.
Further, to make upward guide piece 21 be able to maintain the state in pressure, the length of the fixed column 211 can be big
In the height of upward guide piece 22, i.e., after upward guide piece 21 is covered completely on upward guide piece 22, fixed column 211 can be by upward guide piece 22
Through hole 221 lower openings at stretch out, the end of fixed column 211 be provided with diameter be greater than shaft diameter stop platform
212, the sliding groove that twice are slided for upward guide piece 22 to 122 direction of side plate of the other side is provided on original copy pallet 121
123, after upward guide piece 22 is mounted in sliding groove 123, two through holes 221 thereon respectively with two 123 positions of sliding groove
Corresponding, when fixed column 211 in through hole 221 by being pierced by, the stop platform 212 of end can guide instantly across sliding groove 221
When part 22 is moved to the end of sliding groove 123, the plane that the relatively fixed column 211 of stop platform 212 protrudes can be by the side of sliding groove 123
Side bumper lives to deviate from, and so as to make upward guide piece 21 be fixed on current depressed state, and then protects combined type side plate 2 always
It holds in present level, preferably to operate the small size original copy of clamping.
For the disengaging for preferably preventing fixed column 211, as shown in fig. 7, the end of sliding groove 123 can be arranged to shrink
Diminution portion 124, end here refer to sliding groove 123 close to the end of another block of side plate 122, the sky of sliding groove 123 at this time
Gap width is greater than the diameter of stop platform 212, and the gap length in diminution portion 124 is then less than the diameter of stop platform 212 and is greater than solid
The shaft diameter of fixed column 211, when the upward guide piece 22 under compressive state is moved to diminution portion 124, the shaft of fixed column 211 can
To enter diminution portion 124, and the stop platform 212 of end is then reduced portion 124 and blocks, as shown in figure 8, can by diminution portion 124
More stably stop platform 212 to be limited in sliding groove 124.
Under aforementioned structure, the diameter of stop platform 212 needs to be less than the internal diameter of spring 23.
In an embodiment of the utility model, on the one side that upward guide piece 22 clamps original copy, interval setting
Protrusion and perpendicular to the raised line of original copy pallet 121 222, raised line 222 can be directly to be suppressed by the side of upward guide piece 22 and be formed,
The one side that raised line 222 is contacted with original copy is plane, while being arranged corresponding with 222 position of raised line on upward guide piece 21 and can accommodate
The open slot 213 of raised line 222.
At 21 sets of upward guide piece when on upward guide piece 22, the fixed column 211 in upward guide piece 21 is inserted in positioned at lower guidance
In the through hole of part 22 in 221 spring 23, and the open slot 213 of upward guide piece 21 is then by the two sides of raised line 222 by raised line
The insertion of 222 clampings, the outer surface of the raised line 222 after installation is parallel with the outer surface of upward guide piece 21, which can make
Guiding piece 21 is installed more stable.
In addition, to avoid tangling original copy, the corner for the one side that upward guide piece 22 and upward guide piece 21 contact original copy is all used
Chamfered, making corner all is smooth arc, avoids tangling original copy.
Although the description of the several embodiments of the utility model, but these embodiments are intended only as example and propose
, it is not intended to limit the scope of the utility model.These new embodiments can be implemented with various other ways,
In the range of not departing from the main idea of utility model, it is able to carry out various omissions, displacement, combination and change.These embodiments
It is all contained in the scope of the utility model and main idea, and is contained in originally practical new documented by claims with its deformation
In type and its equivalency range.
