Abstract
The utility model relates to the technical field of image scanning of transmission papers, consisting of a reflector with two reflective surfaces. The reflector is arranged in a shell. The included angle between the two reflective surfaces in elevation view is 90 DEG, while the included angle between the reflective surfaces and a side elevation is 1DEG to 5 DEG. Both ends of a soleplate of the shell are respectively provided with a beam entrance port and a beam exit portal. The utility model has the advantages of simple structure, low price, excellent image quality, etc. Moreover, the utility model can directly image the reflection paper beam into transmission paper beam without any modification to the structure of a current scanner, so that the utility model can be used for a common home-use reflective scanner to realize scanning of transmission papers.
Description
Technical field:
The utility model belongs to the image scanning technical field of transmission original text, and particularly a kind of conversion equipment that utilizes reflective scanning mode instrument scanning transmission manuscript base picture is generally used for the scanning to film base negative film or positive.
Background technology:
Main scanner is two kinds of nontransparent original text scanner and transmission original text scanners for the reflection original text on the market, and its structure as shown in Figure 1.The light source 2 that wherein reflects the original text scanner is arranged on the below that is scanned image, and light shines from reflection original text light source 2 and is scanned on the reflection original text 1, and light reflected reflects through reflective mirror, shines on the photoelectric sensor, thereby realizes image scanning.And transmission original text 1 needs transmission original text light source 3 sides disposed thereon, and light shines on the transmission original text 1 that is scanned from transmission original text light source 3, and light passes transmission original text 1, and the light after the transmission shines on the photoelectric sensor 5 through reflective mirror 4 reflections, realizes image scanning.
Because to transmission manuscript base picture accurately and the market demand of scanning clearly bigger, so existingly realize that the solution of transmission original text scanning is more.Mainly comprise following several.
One, reflection of two fluorescent tubes and transmission original text scanner: this scheme is mainly used in high-grade professional scanner, and it utilizes two fluorescent tubes respectively as reflection original text light source and transmission original text light source, thus realize can the scanning reflection original text also can the scanning transmission original text.
This scheme needs two cover gearings, and a cover drives reflection original text light source 25 and moves, and another set of drive transmission original text light source 27 moves.The structure of this device as shown in Figure 2, mainly comprise by motor 21, gear set 22, the two cover kinematic trains that guide rail 23, the scanning headstock 24 and belt 26 are formed are though this scheme can realize the scanning of transmission manuscript base picture, but it is comparatively complicated that weak point is a structure, part is more, and cost is higher, can only be applicable to the professional scanner that some are senior.
Two, single fluorescent tube sweeping scheme: utilize the light source of reflection original text scanning, promptly the light that will reflect original text light source 1 by methods such as reflections shines on the transmission original text from the top of transmission original text, thereby provides the light source that scans for the transmission original text.As shown in Figure 3, catoptron 33 will reflect illumination that original text light source 31 sends and be mapped in the light guide plate 32 after the homogenising light source as scanning transmission original text 34.This scheme weak point is that the light guide plate material price that adopts is higher, and the light intensity uniformity coefficient is relatively poor, and the transmission manuscript base is not high as quality of scanning.As the adapter of normal domestic use scanner transmission original text scanning, image quality is general and it is on the high side.
Summary of the invention:
The purpose of this utility model is for overcoming the weak point of prior art, provide a kind of price lower, and the higher transmission original text scanning adapter of image quality.In the normal domestic use reflective scanning mode instrument that can be used for generally using, have simple in structure, price is lower, advantages such as image quality is better, and need not carry out any modification to the structure of existing scanner, can be transmission original text light source directly, be applicable to the scanning of normal domestic use reflective scanning mode instrument realization the transmission original text with reflection original text source imaging.
A kind of transmission original text scanning adapter of the utility model design, it is characterized in that, comprise the refractive body that is installed in the housing with two reflective surfaces, said two reflective surfaces are 90 degree at the angle of front elevation, reflective surface is 1 to spend to 5 degree at the angle of side view and surface level, these housing base plate both ends have the entrance port and the exit portal of light beam respectively
The anchor clamps of clamping film base can be installed under this base plate.
The original screen panel that has horizontal raster also can be installed by exit portal place at said housing base plate.
The technical solution of the utility model is single fluorescent tube sweeping scheme, its principle is to utilize A4 breadth reflective scanning mode instrument, the scanning fabric width is the characteristics of 220mm, the light that reflection original text light source during the scanning of reflection original text sends enters the transmission original text scanning adapter of the present utility model from a side, scan the reflection of the refractive body in the adapter again by the transmission original text, light penetrated from the opposite side of transmission original text scanning adapter shine on the transmission original text, thereby the light source of scanning is provided for the transmission original text.
At the characteristics of the headstock in the reflective scanning mode instrument, light path of the present utility model as shown in Figure 4 and Figure 5.
Fig. 4 shows the front elevation of light path in the transmission original text scanning adapter, reflect original text light source (luminous lamp tube) 41 as seen from the figure and be imaged as luminous lamp tube as 43 by reflective surface 42, luminous lamp tube is imaged as luminous lamp tube as 44 by reflective surface 45 again as 43, then luminous lamp tube just becomes the light source that is scanned the transmission original text as 44, and its light that sends has just shone on the scanning copy 46.Wherein reflective surface 42 is 45 degree with the angle of reflection original text light source (luminous lamp tube) 41, and reflective surface 2 is 90 degree with the angle of reflective surface 5.
Fig. 5 shows the lateral plan of the light path in the transmission original text scanning adapter and the scanner headstock, reflection original text light source (luminous lamp tube) 41 is imaged as transmission original text light source (luminous lamp tube picture) 42 by reflective surface 43, thereby make its light that sends pass transmission original text 44 accurately, be irradiated in the scanner headstock, the optical system 45,46,48,49,50 in the headstock is imaged onto on the photoelectric sensor 47.Wherein the angle of reflective surface 43 and surface level be generally 1 spend to 5 the degree.
Characteristics of the present utility model:
1) simple in structure, so the low needs that are applicable to normal domestic use of price
2) directly will reflect the original text source imaging is transmission original text light source, so image quality is better near professional transmission original text scanner
3) need not carry out any modification to the structure of existing scanner, as long as the transmission original text of additional this patent scanning adapter just can be realized the scanning to the transmission original text.
