Description

Mobile scanning

The utility model relates to a kind of scanner that is used for scanning image, object etc., especially a kind of mobile scanning.

Existing scanner commonly used generally can be divided into hand-held motion scan instrument and desk-top scanning constant instrument two big classes, the former moves forward into line scanning by manpower, cost is lower, can under the cooperation of drive software, adopt the method for " blocked scan, abandon dress up total " to realize scanning to the large format image, but must be during because of scanning by manpower motion scan instrument, be difficult to realize straight line, uniform speed scanning, easily cause pattern distortion; The latter can be in certain breadth scope by motor-driven carry out at the uniform velocity, rectilinear scanning, though can realize undistorted scanning, cost is higher, limited by breadth and can not scan plan view image other object outward.Now also has a kind of self-propelled hand held scanner, can carry out at the uniform velocity plan view image, rectilinear scanning, but it needs to contact and could walk with plan view image, makes its scope of application limited: can not scan the on-plane surface image, can not the plan view image that should not directly contact be scanned.

The purpose of this utility model provides a kind of mobile scanning that does not need directly to contact with sweep object and can carry out rectilinear scanning.

The utility model is achieved in that on the scanner main body of being made up of light source, scanner head, sweep signal treatment circuit and holding components thereof etc. sets up one group of wheel that is no less than two, and a pair of guide rail that has race that is propped up placement that part supports, parallel by guide rail is set, above-mentioned wheel moves along the race of this guide rail, thereby makes the scanner main body carry out rectilinear motion along guide rail.

The further purpose of the utility model is to make above-mentioned scanner can also realize uniform speed scanning.

Its implementation is as follows: driven wheel is installed as driving wheel on the axle of at least one wheel in above-mentioned one group of wheel, and on the scanner main body, further set up the power source that can drive this driving wheel uniform rotation, as mechanical clockwork spring, motor and driving circuit thereof etc., this power source is meshed with driven wheel on the above-mentioned drive sprocket axle by the gear on its turning axle, power can be passed to driving wheel and make its uniform rotation, carry out linear uniform motion along guide rail thereby drive the scanner main body.

Further, an activity can be set cover the spire lid, when scanning, this top cover be covered on scanner main body and the guide rail, to shield extraneous parasitic light in order to weaken of the influence of extraneous parasitic light to the scanning effect.

The utility model has the advantages that:, do not carry out linear uniform motion and do not need directly to contact, admittedly can realize contactless, undistorted scanning to sweep object with sweep object along above-mentioned guide rail because of the scanner main body can be under the driving of above-mentioned power source.

Below in conjunction with accompanying drawing the utility model is described in detail:
