Description

Image input bare engine module and drive mechanism device

The utility model relates to a kind of image input bare engine module and drive mechanism device, relates in particular to described bare engine module and is provided with the drive mechanism that can supply transmission and guide function, to become modularization and to reach the innovative device that reduces cost.

Flat bed color image scanners (Flat Bed Image Scanner) is very universal now computer peripheral equipment, that is, it can be with data such as literal such as file, magazine, books, picture, chart and pictures, with in the scanning input computer apace and handled again; Moreover this flat bed color image scanners owner will be made up of members such as image input media, gearing, image-processing circuit, transparent scanning window and housings; So, flat bed color image scanners system causes the image input media and the gearing that wherein take up space towards light, thin, short, little development now, the main object that makes its minimizing take up room even if become the research and development improvement.

As shown in Figure 1, known image input media 1a comprises members such as light source, reflector group, camera lens and image sensor, in addition, gearing 2a then comprises members such as step motor 20a, gear set 21a, idle pulley 22a, endless-belt 23a and sliding guide 24a.

Moreover the principle of work of general flat bed color image scanners is as follows:

At first, the file of desire scanning input is positioned on the transparent scanning window, after the light source irradiation by image input media 1a, even the reflected light that is produced is via reflector group and camera lens, and reach to image sensor, and this image sensor system delivers to image-processing circuit with signal of video signal and is quantized, and imports computing machine then and does to handle further; And after image sensor was finished a row signal of video signal, this gearing 2a was about to image input media 1a and moves to next district to be scanned, until whole image read finish till.

Again, as shown in Figure 1, aspect power system, the step motor 20a of this gearing 2a and gear set 21a system all are fixed on the scanner housing, and this gear set 21a system is connected in the end of annular belt 23a, and the other end of this annular belt 23a then is connected on the idle pulley 22a, and by the driving of this annular belt 23a, and make this image input media 1a do moving of translation along sliding guide 24a, to finish the action of image scan.

This image input media 1a and this gearing 2a are the design that is separated into two parts, and this gearing 2a system is arranged on the scanner housing, thereby cause the waste of the inner space of scanner housing, and not quick detachable or assembling, so, on reality is used, obviously have inconvenience and exist, and await being improved with defective.

And, along with scanner is constantly weeded out the old and bring forth the new, its resolution and image quality also constantly promote, so, the fieriness of market free competition causes the scanner price constantly to glide, and in the face of grow up day by day competition with price of market, and how to shorten man-hour and reduce cost the target that reality reaches for the relevant required effort of dealer.

In view of this, the clever thought that the special utilization of the utility model people is original and the application of scientific principle, and accumulation is engaged in relevant professional development and production and sales experience for many years, and several times trial-production is done with real, can develop eventually a kind of assembling and maintenance man-hours of reducing to reach the innovative product that reduces cost.

The utility model purpose is to provide a kind of image input bare engine module and drive mechanism device, it mainly is designed to bare engine module (Optical Module) and drive mechanism the modular unit of one, with part and the program of simplifying its assembling, and then the man-hour of reducing assembling and maintenance, and to reach the purpose that reduces cost.

In order to achieve the above object, the utility model system provides a kind of image input bare engine module and drive mechanism device, and it includes a bare engine module, a transmission component group and a guide member group; Wherein, described transmission component group cording has a step motor, and it is set up on the described bare engine module, and described step motor system is arranged with a driving gear, and described driving tooth train is engaged in first follower gear, and the described first driven tooth train is engaged on the tooth bar; Again, described guide member group is to be provided with second follower gear that is engaged in described first follower gear, and the described second driven tooth train meshes another on another tooth bar, and by the action that is meshing with each other between above-mentioned follower gear and two tooth bars, with the function with transmission and guiding; In addition, described guide member group also can be made as a female guide seat and and cooperate the public guide seat that operates for described female guide seat, with the guiding as described bare engine module; By this, bare engine module of the present utility model is to can be a kind of modular design with transmission and guide function, to reach the effect that reduces cost.
