Abstract
The utility model relates to an improved driving device of an optical scanner, which utilizes a simple ring-shaped structure to achieve the purpose of keeping the optical path unchanged. The utility model is mainly composed of a driving gear, a plurality of driven rolling wheels, a group of deceleration rollers, a group of idle pulleys and an annular driving element; the annular driving element is connected with the driving gear, the driven rolling wheels, the deceleration rollers and the idle pulleys to drive a lamp tube loading device and a reflector seat, and therefore, when the lamp tube loading device moves forward by one unit distance, the reflector seat moves forward simultaneously by 1/2 unit distance.
Description
The utility model is a kind of gearing of optical scanner, refers to a kind of annular gear that is applied to two bogeys especially.
The kind of drive of known platform-type optical scanner can be divided into single bogey and two bogey generally.Single bogey is for to be installed in all optics modules on the same bogey, so its volume is bigger.For making its volume-diminished, be the design that two bogeys are arranged.
Two bogeys refer to fluorescent tube bogey and the mirror unit in the optical scanner.For the light path kept in the scanner is constant, when the design of its gearing must make the fluorescent tube bogey take a step forward, mirror unit was taken half a step forward before only.Therefore, known two bogeys, just as the very complicated precision of the gearing of ball slide bar type or cable wire roller type, and involve great expense.Referring to the just complexity of its structure as can be known of Fig. 1.
Fig. 1 shows the gearing of a cable wire roller type.As shown in Figure 1, optical element such as fluorescent tube 102 are fixed on the fluorescent tube bogey 101, and catoptron then is installed on the catoptron bogey 103.Its roller 104,105,106,107 be positioned at board around, and connect fluorescent tube bogey 101 and catoptron bogeys 103, so that fluorescent tube bogey 101 is kept suitable distance and direction with advancing of catoptron bogey 103 with cable wire 108.As shown in Figure 1, constant for keeping light path, the structure of the element of the scanner of two bearing-types is very complicated, and because spare part is many, and its assembling is quite time-consuming, and maintenance is difficult for.
Fundamental purpose of the present utility model, makes the optical scanner of two bearing-types be easy to assembling and maintenance, and then reduces cost to simplify the actuated element of two bogeys at the gearing that proposes a kind of optical scanner simple in structure, improves production capacity.
Another purpose of the present utility model is proposing a kind of annular gear, improving two bearing-type drive mechanisms of known complexity, and makes advancing of fluorescent tube bogey and mirror unit more smooth-going.
For achieving the above object, the utility model mainly drives element by a driving gear, a plurality of passive rolling, one group of reduce roll, one group of idle pulley and an annular and is formed, wherein should connect this driving gear, passive roller, reduce roll, reach idle pulley with circular pattern by annular drive element, to drive fluorescent tube bogey and mirror unit, when making this fluorescent tube bogey advance a unit distance, mirror unit is simultaneously with marching forward 1/2 unit distance.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the drive mechanism figure of known cable wire roller type.
Fig. 2 is the side view of annular gear of the present utility model.
The emphasis of the utility model design is utilizing the arrangement of roller, cooperates the actuated element of annular, so that the fluorescent tube bogey advances during a unit distance, mirror unit can be simultaneously with marching forward 1/2 unit distance, and is constant to keep light path.And actuated element of the present utility model can make assembling and keep in repair more convenient all in the same side of body.
Structure of the present utility model as shown in Figure 2.Fig. 2 shows the side structure of a platform-type scanner, and the board 201 of platform-type scanner is a square structure, and there is a transparent file base station 202 top, to place file.Board inside mainly comprises a fluorescent tube bogey 203, a mirror unit 204, an image fetch device 205, reaches an annular gear 206.
The power resources of full annular gearing are from a driving gear 215.Driving gear 215 and connects a motor (not being shown in figure) between the first passive roller 207 and the 4th passive roller 210, changed the direction of rotation by the driving of motor.Driving gear 215 connects and driving actuated element 206.During scanning, driving gear 215 rotates to clockwise direction, drives the 4th passive roller 210 simultaneously, makes it to counterclockwise rotating, and also makes fluorescent tube bogey 203 unit distance of advancing simultaneously.The 4th passive roller 210 drives first reduce roll 213, because the principle that pulley reduces by half, first reduce roll 213 is to counterclockwise rotating, and drives mirror unit 204 1/2 unit distance of advancing simultaneously in the same way.In like manner, when fluorescent tube bogey 203 was return original position, driving gear 215 drove the 4th passive roller 210 simultaneously to counterclockwise rotating, and it is rotated to clockwise direction, also made fluorescent tube bogey 203 return a unit distance simultaneously.Because the principle that pulley reduces by half, first reduce roll 213 rotates to clockwise direction, drives mirror unit 204 in the same way simultaneously and retreats the half unit distance.In order to make actuated element 206 when rotating, keep suitable pulling force, install a spring 216 in the place of the contiguous second passive roller 208, to keep the tension force of actuated element.
With regard to its light path, file is positioned on the file base station 202 during scanning, and the lamp source is upwards irradiation from fluorescent tube bogey 203.The reflection image penetration microscope base 204 and with the reflection image be delivered to image fetch device 205, to change image into digital signals.Because can making fluorescent tube bogey 203 and mirror unit 204 advance, actuated element 206 keeps suitable distance, so can guarantee that light path is constant.
Of the present utility model simple in structure, can reach really and keep the constant purpose of light path.The structure of annular not only can make advancing of fluorescent tube bogey and mirror unit more smooth-going, and can reduce the error of light path.In addition, this actuated element all is positioned at the same side of board, and spare part is few, and is easy to assembly, can improve production capacity, advances face and reduces cost.The above only is preferred embodiment of the present utility model, and has reached practical effect widely, and all equalizations of doing according to the utility model change and modify, and should think still to belong in the scope that the utility model patent contains.
