Background technology
Existing Plate making printing all-in-one sweep mechanism is the imageing sensor CIS (contact image sensor) of row's scanning element for the row's sensing element that has consistent with scanning width.The imageing sensor of the scanning of width makes its cost very high because of manufacture difficulty is high greatly.In addition, realize the higher scanning of precision, improve quality of scanning, also need strengthen the density of sensing element on same imageing sensor, this also increases manufacture difficulty and manufacturing cost undoubtedly greatly.
Goal of the invention
The objective of the invention is to: design a kind of method and simple in structure, can realize extending and improve the Plate making printing all-in-one scan method of scanning accuracy and realize the sweep mechanism of this method.
The present invention is a method of utilizing imageing sensor short or that sensor element density is lower to realize increasing scanning width or improve scanning accuracy, its technical scheme comprises the imageing sensor that has sensing element, it is characterized in that: it adopts at least two row's sensing elements, it is overlapped that each arranges at least a portion of sensing element, between two adjacent sensing elements of two row's sensing elements of lap along with the distance of row's sensing element direction more than or equal to 0, smaller or equal to the distance between two adjacent sensing elements in row's sensing element, utilize sensing element to scan.
In said method, can only make and respectively arrange in the sensing element some and carry out overlappingly, also can be all overlapping.
In addition, each can be arranged sensing element widens along the scanning direction, it is overlapping promptly to adopt the two row or multi-row sensing element to carry out, and respectively arrange between sensing element along with the distance of row's sensing element direction greater than 0, less than with the distance between two adjacent sensing elements in row's sensing element, this method can realize on the whole along the increase with row's sensing element direction sensing component density, thereby improve scanning accuracy.
Realize the sweep mechanism of said method, comprise the imageing sensor that has sensing element, it is characterized in that: it has at least two row's sensing elements, it is overlapped that each arranges at least a portion of sensing element, between two adjacent sensing elements of two row's sensing elements of lap along with the distance of row's sensing element direction more than or equal to 0, smaller or equal to the distance between two adjacent sensing elements in row's sensing element.Wherein, each is arranged in the sensing element can be that part is overlapped, also can be all overlapping.Utilize partly overlapping method further each row's sensing element to be designed to the overlapping mode of head and the tail successively, realize the increasing of scanning width thus.
When improving scanning accuracy, each row's sensing element is overlapping, and make respectively arrange between sensing element along with the distance of row's sensing element direction greater than 0, less than with the distance between two adjacent sensing elements in row's sensing element.
In addition, the present invention can adopt existing imageing sensor to realize, promptly each imageing sensor has row's sensing element, also can adopt the imageing sensor that contains a few row's sensing elements, and each imageing sensor is connected by support.
This shows, utilize structure of the present invention can utilize lower-cost imageing sensor to realize improving scanning accuracy or increasing sweep limits.
