Description

Cylindrical contact picture and text sensor

The utility model relates to a kind of sensor, especially for the sensing device of photo scanning imaging and facsimile recorder.

One of critical component in photo scanning imaging devices such as facsimile recorder, scanner is exactly a sensor, and used in the drum type scanner that occurs at present and some facsimile recorders be exactly the contact image sensor (hereinafter to be referred as CIS) of cuboid.Use on the flat glass of this sensor carrying manuscript and be pressed with a rotating round roller, when the circle roller rotates, drive manuscript and move, like this can be to the manuscript scanned imagery.But because glass is a static plane, when the circle roller rotates will to manuscript produce a resistance or resistance inhomogeneous, phenomenon such as cause paper to be blocked or paper feed is crooked.Also have, the single page manuscript can only be faxed or scan to this sensor, then seems powerless for the books that can not at will take apart.

The purpose of this utility model is exactly at the deficiency described in the above-mentioned background technology, solves paperboard or paper feed is crooked and the picture and text sensor that can scan books and provide a kind of.

To achieve these goals, the utility model proposes the corresponding techniques solution:

This cylindrical contact picture and text sensor is fixed on lens and leaded light bar on support, fixing in the circuit board with respect to the sensitization crystal grain that lens are provided with, it is that mainly cylinder is connected with axis by digital disk and bearing.Be provided with photocurrent generator and photelectric receiver in the both sides of digital disk.Said support, lens, leaded light bar, sensitization crystal grain and wiring board all are positioned at cylinder, and its medium-height trestle and axis are fixed.Also a digital counting device can be set in a side of digital disk, on digital disk, be provided with reflector plate.

Below with reference to drawings and Examples the utility model is done a description.

As shown in Figure 1 and Figure 2, the utility model mainly is to be made of cylinder 1, axis 8, digital disk 3, bearing 6 and support 7, lens 9, leaded light bar 10, sensitization crystal grain 11, wiring board 12.Wherein, cylinder 1 is the hollow cylinder shape of being made by light transmissive material such as glass or organic glass etc.One end of cylinder 1 is fixed with digital disk 3 (referring to Fig. 3).Be respectively equipped with photocurrent generator 2 and photelectric receiver 5 in the both sides of digital disk 3, they both can correspondence be fixed on the axis 8, also photocurrent generator 2 can be fixed on the support 7 that is positioned at cylinder 1, and photelectric receiver 5 is fixing with axis 8.Said support 7 and the lens 9, leaded light bar 10, sensitization crystal grain 11, the wiring board 12 that are fixed on the support 7 all are positioned at cylinder 1, and support 7 links to each other with axis 8.Said cylinder 1 directly with after digital disk 3 links to each other joins by bearing 6 and axis 8 again, so, when in the enterprising line scanning of manuscript, although how cylinder 1 rolls on manuscript, and axis 8 and the support 7, lens 9, leaded light bar 10, sensitization crystal grain 11, the wiring board 12 relative cylinders 1 that link to each other with axis 8 are actionless.The irradiate light that is penetrated by leaded light bar 10 reflects behind the manuscript surface again and enters lens 9, can be with the visual scioptics 9 on the manuscript and imaging on sensitization crystal grain 11, after handling by a series of circuit on the wiring board 12 then facsimile signal is directly inputed in computing machine and the corresponding apparatus by axis 8 places.

Also cylinder 1 and digital disk 3 can be fixed on simultaneously link to each other with axis 8 again on the bearing 6 (referring to Fig. 2).

Also a digital counting device 13 can be set in a side of digital disk 3, on digital disk 3, be interval with reflector plate 16.The irradiate light of sending by power valve 14 in the digital counting device 13 reflected back receiving tube 15 again behind the reflector plate 16 that is positioned on the digital disk 3, receiving tube 15 receives the reflected signal of interruption, and input to and carry out data processing in the follow-up relevant device, thereby tally function of finishing (referring to Fig. 4).

When cylinder 1 rolls on manuscript gradually, coupled digital disk 3 also rotates synchronously, hole 4 promptly produces blocking-up at interval to light or the electric signal that is sent by photocurrent generator 2, and photelectric receiver 5 receives to input to behind conductings and the disabling signal and carries out data processing in the follow-up relevant device, to carry out the out of Memory of data processing in the displacement that draws this sensor and the relevant device.

Hole 4 on the digital disk 3 can be made into multiple geometric configuratioies such as circle, square, rectangle, ellipse, triangle.

Two above-mentioned said sensors are used simultaneously, also can the picture and text on manuscript two sides be scanned simultaneously, more accelerated the speed and the efficient of scanning.

Ingenious, the novel structure of the utility model design, by relatively rotating of the relative sensing element of rotatingcylindrical drum, Both solved deficiency described in the prior art, this device can have been taken out from scanner again and hand-held scanning books literary composition Original text, the record efficiency height is directly imported computer with the picture and text information of scanning gained and is carried out corresponding processing.
