Description

543318 V. Description of the Invention (1) [Field of the Invention] The present invention relates to a scanning light source module, and more particularly, to a light source module that scans through manuscripts. [Inventor's back: For the regular person, according to the shooting and wearing objects are anti-objects and wearing, and still need to be equipped with a photo-mechanical platform platform type scanning traditional type, the moving element element moving plate 'light source is complicated, The backlight of a piece of backlight type is a whole piece of backlight progress and the lack of pictures must be light, for example, film, cast through the manuscript source can be installed behind the manuscript to facilitate the focus. The light source uses a movable mask. The area of the lamp tube bears the shaft rod. The lamp is usually used. The scanning technology requires the text to be unavailable. Scan the light from the top to provide a penetrating group to achieve the design of the group scanner. Provide a mask. The backlight will be distributed at least. At the same time, the mask will be produced. At the same time, a mask is required to emit light. However, market demand Data into a backup tool. The same reaction can be used for photos, printed videos, plus and minus light sources in addition to scanning. However, the cost is constantly changing. The electronic document editor will scan the originals and various films and slides. How to design the scanner is the goal of the scanner. The methods can be divided into moving-type and backlight-type tube design. The scan will use a backlight field that emits light as a whole. However, the mechanism within the moving-type photomask involves subtle issues such as load-bearing components, two shaft rods, and the parallelism of the driving horse: components such as acrylic, reflective sheets, etc. make the cost higher and there will be uneven light source distribution. Scanner processing is divided into anti-opaque and other light-transmitting sources, and a photomask must be installed inside to become 543318.

Equality issues. [Objective and Summary of the Invention] In view of this, the objective light source module of the present invention uses a simple mechanism to light the light source to reduce the internal mechanism of the photomask.

Transmissive scanning light source module; is a mechanism module installed in the photomask 100, which provides scanning light source for light source; penetrating scanning light source module includes: scanning lamp tube group, reflective lens group 106 and motor mechanism 108. The scanning lamp group is fixed to the photomask 100 and provides a light source; as shown in Fig. I, the scanning lamp group has two lamp groups respectively arranged on the left and right sides, and the first lamp 丨 02 It is fixed to the left side of the mask housing ΐ (π and connected to the first lamp reflection sheet 102a, and the second lamp 104 is fixed to the right side of the mask housing 101 and connected to the second lamp reflection sheet l 〇4a. The reflection lens group 106 is located between the first lamp tube 102 and the second lamp tube and is slightly higher than the first lamp tube 102 and the second lamp tube 104. The reflection lens group 106 and the motor The mechanism 108 is coupled and can be rotated by the drive of the motor mechanism 108. Its rotation angle is less than one hundred and eighty degrees. Please refer to Figs. 2A and 2B at the same time, and show a side perspective of a scan penetrating through the manuscript. Figure and its light path. The device for scanning through the manuscript includes a mask 200 and a scanner body 210. The mask 200 is arranged above the scanner body 21 and is electrically connected to the scanner body 210. To be scanned The penetrating manuscript gig is placed on the glass 214 of the scanner body 210, and the penetrating manuscript 216 is covered when the mask 2000 covers the scanner body 210. It can be flatly fixed between the photomask 200 and the scanner body 210. A transmissive scanning light source module is provided in the photomask 200, and the photosensitive module 2 1 2 is disposed on the scanner body 2 10. The penetrating scanning light source module has a scanning lamp tube group, and the first lamp tube 202 and the second lamp tube 204 are fixed to the left end of the mask housing 201 and the right of the mask housing 201, respectively. Side end, ^

543318 V. Description of the invention (4) A reflecting lens group 20 6 is arranged on the upper plane between the first lamp tube 202 and the second lamp tube 204. The reflection lens group 206 is coupled to the motor mechanism 208, and can be coupled in a coaxial manner as shown in FIG. 1 or can be indirectly connected by using transmission elements such as a transmission belt 209. The motor mechanism 208 controls the rotation angle of the reflection lens group 206 according to the moving position of the photosensitive module 212, so that the light emitted by the scanning lamp tube group can pass through the rotation and reflection of the reflection lens group 206. One end of the transparent manuscript 216 is irradiated to the other end of the transparent manuscript 216 to completely scan the transparent manuscript 216. In Figure 2A, the position of the photosensitive module 2 1 2 is closer to the first light tube 202 on the left side. At this time, the mirror surface of the reflective lens group 20 6 is biased to the left, and the light received by the penetrating manuscript 216 is mainly Department from the first light tube 202. When the first lamp tube 202 emits light, the brightness of the light is increased through the first lamp tube reflection sheet 202a, and the light will be irradiated to the reflection lens group 206, and then the reflection lens group 206 will focus the light to penetrate Manuscript 2 1 6, where the light-concentrating position can correspond to the position of the photosensitive module 2 1 2, so light can penetrate the manuscript 2 丨 6 to reach the photosensitive module 2 1 2. In Figure 2B, the position of the photosensitive module 2 1 2 is closer to the second lamp tube 2 0 4 at the right end. At this time, the mirror surface of the reflective lens group 2 6 is biased to the right, penetrating the one received by manuscript 216. The light mainly comes from the second lamp tube 204. When the second lamp tube 204 emits light and the brightness of the light is increased through the second lamp reflection sheet 204a, the light will be irradiated to the reflection lens group 206, and the reflection lens group 206 will focus the light to penetrate Manuscript 2 1 6 'Where the light-concentrating position can correspond to the position of the photosensitive module 2 1 2, so light can pass through the manuscript 2 1 6 to reach the photosensitive module 212. Since the light reflected by the reflection lens group 206 to the penetrating draft 216 is mainly from the lamp tube at the side closer to the position of the photo-sensitive module 2 1 2,

543318, description of the invention (5)-The lamp on the side can be selectively turned off until the photosensitive module 2 1 2 moves and approaches the other side, and then the lamp on the other side is turned on. During the scanning process, the photosensitive module 2 1 2 moved from one end (left side) to the other end (right side) of the scanner, and the motor mechanism 2 08 also synchronously driven the reflective lens group 2 6 (in a counterclockwise direction). Rotating not only allows the light-sensitive module 2 1 2 to accurately receive the transmitted light, but also uniformly provides the backlight light source required for scanning through the manuscript. [Effects of the Invention] # The penetrating scanning light source module disclosed in the above embodiments of the present invention can provide a backlight source required for scanning through manuscripts by using a simple mechanism, which can not only reduce the complexity of the internal mechanism of the photomask, but also It can reduce the problem of micro-production of the mechanism, and the simple cost of the simple mechanism design can reduce the cost of the desktop scanner and achieve the goal of easy assembly. It has been disclosed in the preferred embodiment that any person skilled in the art can make various modifications and retouches without departing from it. Therefore, the scope of the patent application is defined as above, although the invention is not intended to limit the invention.
