Description
Technical field
The utility model relates to scanner field, be specifically related to a kind of for LED lamp the large format scanner as scanning light source.
Background technology
Traditional large format scanner is all to adopt negative electrode cold light source to irradiate to be scanned, and this scanner has following deficiency:
1, after start, need the warm-up time through about 20 minutes, could normally use;
2, the life-span of light source short, need often to change light source;
3, negative electrode cold light source manufacture craft difficulty, thus draw high cost of manufacture;
4, brightness is low.
Utility model content
The purpose of this utility model is to provide a kind of large format scanner, realized start without preheating, save energy consumption, large format scanner that cost is low.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of large format scanner, comprise pedestal, the bilateral symmetry of described pedestal is provided with leading screw frame, the described leading screw frame leading screw that is rotatably connected, described leading screw is fixedly connected with motor by shaft coupling, described motor is fixedly connected with pedestal by motor cabinet, described threads of lead screw connects scan table, the both sides of described scan table are respectively equipped with probe and lamp bracket, in described lamp bracket, the position of corresponding described probe is provided with reflective mirror, the angular range of described reflective mirror is that 30 degree are to 60 degree, the top of described reflective mirror is provided with cavity, the top bilateral symmetry of described lamp bracket is provided with some LED lamps, the top of described LED lamp is provided with transparent panel, the two bottom sides of described lamp bracket is equipped with balance plate.
Further, described LED lamp be shaped as strip.
Further, between described LED lamp, be parallel to each other.
Further, the quantitative range of described LED lamp is 1-3, is preferably 2.
Further, the top of described transparent panel is provided with the silicagel pad of horizontal positioned.
Further, the angle of described reflective mirror is 45 degree.
The beneficial effects of the utility model are:
1, realized start and directly used, without preheating;
2, improve the useful life of scanner light source;
3, energy-conservation, reduce costs;
4, increase brightness, scan to obtain definition thereby improved.
Brief description of the drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the side-looking structure chart of sweep optical square described in the utility model embodiment;
Fig. 2 be in Fig. 1 A to enlarged drawing;

Embodiment
As Figure 1-3, a kind of sweep optical square described in the utility model embodiment, comprise pedestal 1, the bilateral symmetry of described pedestal 1 is provided with leading screw frame 2, described leading screw frame 2 connects leading screw 3 by bearing rotary, described leading screw 3 is fixedly connected with motor 4 by shaft joint, and described motor 4 is fixedly connected with 4, motor, and 4, described motor is fixedly connected with pedestal 1.
Described leading screw 3 scan table 5 that is threaded, the bottom surface, both sides of described scan table 5 is arranged with balance plate 12, for supporting scan table 5, prevents that scan table 5 from tilting; The upper surface, both sides of described scan table 5 is respectively equipped with probe 6 and lamp bracket 7, described probe 6 is located on the center line of described scan table 5, in described lamp bracket 7, being provided with angle is the reflective mirror 8 of 45 degree, described reflective mirror 8 is located at the center of described lamp bracket 7, for reflection ray, will reflect to probe 6 with the image of scanned copy; The top of described reflective mirror 8 is provided with the cavity 9 passing through for the folded light beam of reflective mirror 8.
The top bilateral symmetry of described lamp bracket 7 is provided with 2 mutually different LED lamps 10 of light direct projection angle, described LED lamp 10 be shaped as strip, between described LED lamp 10, be parallel to each other, for increasing the direct projection scope of LED lamp 10, make phase complementary light between LED lamp 10, thereby realized on to be scanned of being irradiated to of homogenizer.
The top of described LED lamp 10 is provided with the transparent panel 11 for placing to be scanned, and the top of described transparent panel 11 is provided with the silicagel pad 13 of horizontal positioned, for flattening to be scanned, has the function of shading simultaneously.
When concrete use, opening power, first lies on transparent panel 11 to be scanned, then silicagel pad 13 is pressed in to be scanned above, flattens to be scanned, launch computer scanner, make motor 4 drive leading screw 3 to rotate, scan table 5 moves horizontally, and probe 6 obtains scan image by reflective mirror 8 reflections simultaneously, and LED lamp 10 throws light on, increase exposure, make image brighter, probe 6 is transferred to computer by data wire by scan image, computer editing's picture.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
