Abstract
The utility model relates to a contact image sensor relating to an image reading apparatus. A light source is arranged above a frame, a lens is arranged at the middle of the frame, and a basal plate is arranged under the frame. A plurality of sensors are uniformly arranged on the basal plate. One side of the frame is provided with a socket. The sensors are uniformly arranged on the basal plate in a staggered way. Because the sensors are uniformly arranged on the basal plate in a staggered way, the interval between two light openings of the adjacent ends of two adjacent sensors is same as the interval between two adjacent light openings on the sensors. Thus, corresponding original information between the two light openings of the adjacent ends of the two adjacent sensors are correctly and totally reflected. The utility model can read images with high density and is suitable for various contact image sensors.
Description
Technical field the utility model relates to image read-out, says it is a kind of contact-type image sensor in detail.
We know background technology, the employed contact-type image sensors of pattern recognition device such as existing facsimile machine, scanner, be above framework, to be provided with light source, the framework middle part is provided with lens, the framework below is provided with substrate, be the even some transducers of cloth of straight line on the substrate, be the even some light mouths of cloth of straight line on the transducer, the framework side is provided with socket, during work, the light that sends from light source arrives original copy, and reverberation arrives transducer after lens focus, and transducer converts light signal to the signal of telecommunication and exported by socket as image information.This contact-type image sensor, because some transducers are the even cloth of straight line on substrate, make the spacing of facing mutually between two light mouths that two transducers face end mutually greater than two spacings of facing mutually between the light mouth on the transducer, cause and face two transducers mutually and face mutually that pairing original copy information can not correctly reflect fully between two light mouths of end, to high-density reading images.
The technical problem that summary of the invention the utility model solves is, solve some transducers and on substrate, be the even cloth of straight line, make the spacing of facing mutually between two light mouths that two transducers face end mutually greater than two spacings of facing mutually between the light mouth on the transducer, cause and face two transducers mutually and face mutually that pairing original copy information can not correctly reflect fully between two light mouths of end, the problem of reading images to high-density, provide a kind of spacing of facing mutually between two light mouths that two transducers face end mutually identical with two spacings of facing mutually between the light mouth on the transducer, make and face two transducers mutually and face mutually that pairing original copy information can correctly reflect fully between two light mouths of end, to high-density the contact-type image sensor of reading images.
The technical solution of the utility model is, the framework top is provided with light source, and the framework middle part is provided with lens, and the framework below is provided with substrate, the even some transducers of cloth on the substrate, and framework one side is provided with socket, and its primary structure characteristics are that transducer is staggered even cloth on substrate.
The beneficial effects of the utility model are, because transducer is staggered even cloth on substrate, the spacing of facing mutually between two light mouths that two transducers face end mutually is identical with two spacings of facing mutually between the light mouth on the transducer, make and face two transducers mutually and face mutually that pairing original copy information can correctly reflect fully between two light mouths of end, to high-density reading images.The utility model is applicable to various contact-type image sensors.
Appended drawings is a kind of schematic diagram of the present utility model, also is the schematic diagram of a kind of embodiment.Fig. 1 is a front view, Fig. 2 be a kind of A of Fig. 1 to partial enlarged drawing, Fig. 3 be the another kind of A of Fig. 1 to partial enlarged drawing, be labeled as A
1To.
Execution mode as can be seen from Figure 1, framework 6 tops are provided with light source 2, framework 6 middle parts are provided with lens 5, framework 6 belows are provided with substrate 4, the even some transducers 3 of cloth on the substrate 4, and framework 6 one sides are provided with socket 1, during work, the light that sends from light source 2 arrives original copy, and reverberation arrives transducer 3 after lens 5 focus on, and transducer 3 converts light signal to the signal of telecommunication and exported by socket 1 as image information.Transducer 3 is staggered even cloth on substrate 4, as can be seen from Figure 2, the staggered even cloth of transducer 3 biserial on substrate 4, as can be seen from Figure 3, the staggered even cloth of transducer 3 multiple row on substrate 4, because transducer 3 is staggered even cloth on substrate 4, the spacing of facing mutually between two light mouths that two transducers 3 face end mutually is identical with two spacings of facing mutually between the light mouth on the transducer 3, make and face two transducers 3 mutually and face mutually that pairing original copy information can correctly reflect fully between two light mouths of end, to high-density reading images.
Claims (3)
1, a kind of contact-type image sensor, the framework top is provided with light source, and the framework middle part is provided with lens, and the framework below is provided with substrate, the even some transducers of cloth on the substrate, framework one side is provided with socket, it is characterized in that: transducer is staggered even cloth on substrate.
2, contact-type image sensor according to claim 1 is characterized in that: the staggered even cloth of said transducer biserial on substrate.
