Abstract

The present invention relates to a curve type scanner which comprises a main body, a transmission mechanism, a curve type transmission shaft, a curve type file stand and an optical sensing module. When the curve type scanner scans a file, the optical sensing module runs in a curved surface mode; a horizontal divided axle movement vector which is needed by the optical sensing module is short, so the volume of the scanner can be reduced; the curve type scanner can also scan an object with a curved surface in the curve mode; the scanner can also be flatly, or vertically or obliquely put on the table surface.

Description

The shaped form scanner

Technical field

The present invention relates generally to a kind of optical scanner, particularly a kind of scanister of making the curvilinear style scanning document that drives with interlinked mechanism; It connects an optical sensor by an interlinked mechanism, and and then promote optical sensor and on a curyilinear file platform, move, reach the purpose of a file of scanning; Characteristics of the present invention mainly are, improve the waste usage space that platform-type scanner caused and the awkward shortcoming of the great volume of known benzene, and then be modified into curyilinear optical scanning way, reach and save usage space and with getting with collecting purpose easily with use, in addition, in volscan flourish today, the design of curved surface scan mode can more meet stereo article, makes scanning can reach more accurate requirement.

Background technology

See figures.1.and.2, Fig. 1 and Fig. 2 are known plat form type scanning apparatus stereographic maps, the general big portion of known platform formula scanister is the desk-top platform-type CCD optical scanner that is placed on desktop, and when using, the body 11 with this plat form type scanning apparatus is positioned on the desktop earlier, then, file to be scanned is placed on this scanning area, cover loam cake 12 after, connect to go up main frame with connecting line again, pegging graft afterwards to go up on the power supply bonnet hides, and can begin scanning by initiating key.

But the platform-type desk-top optical scanner of conventional known and circuit structure of the present invention mainly all are a kind of main frames of line, and by the optical reader scanister of this Computer Processing picture signal output; It mainly is CCD (CHARGE COUPLE DEVICE) the driver induction driving by image sensing device, and via the multiplexer of establishing in that simulates, then, asynchronous output simulates signal, then amplify by a CCD again and adjust conversion equipment enlarged image signal, offset flip-flop, is storable data image signal through analog-digital commutator with asynchronous output analog signal conversion, at last, via buffer storage data image signal is stored successively again, and the control reflective mirror of the position control by file to be scanned and lamp strip position scan file to be scanned, in a word, this known optical scanning technique is that a kind of CCD of utilization driver induction drives, and the simulation multiplexer of establishing in warp induction drives asynchronous output simulating signal, by voltage adjuster flip-flop is offset (offset) to obtain more accurate waveform, believe interference by the enlarged image signal in order to avoid mix, analog signal conversion is stored as data image signal, by buffer storage storage data image signal, by position control control reflective mirror and lamp strip position to cooperate the scanning of file to be scanned.

Structure for mechanism, the Scan Architecture of the platform-type scanner of conventional known is an a placement desk-top optical scanning structure on the table, and known Flatbed scanner is to be the main body of CCD (the CHARGE COUPLE DEVICE) optical scanner of light source as scanning document with the cathode tube; Though present scanner uses general designation CIS (Contact Image Sensor) to replace the scanning optical element of CCD, but still just like structurally its space and the restriction used of the platform-type scanner of conventional known, as take usage space, must be placed on desktop and carry inconvenience or the like, therefore the special proposition of inventor the present invention, this characteristic feature of an invention promptly be to improve the heavy and large volume of the benzene of conventional known platform-type scanner the waste usage space and use the inconvenient shortcoming of collection, promptly as shown in Figure 2, the structure of conventional scanners needs with platform-type placement on the table, through after the driving of driving element 22, make optical sensor 24 do the scanning of orthoscopic according to the transmission shaft 23 of orthoscopic by drive unit 21.

Based on the shortcoming in the platform-type scanner structure design of above-mentioned conventional known, fundamental purpose of the present invention is to utilize curyilinear optical scanning structural design, makes its scanning usage space during reduced scanning significantly.Can not be subjected to the influence of paper size and cause the length and width of scanner itself to be subjected to great restriction, for example when the file of scanning long strip type, the scanner board of stock size is the file of single pass Great Britain and America letter size fully just, and this is the shortcoming of the scanister of traditional line scanning motion.

Particularly general user's table for computer plane space up and down is limited, can the break traditions external form of scanner of the present invention, and scanning machine is extended to three-dimensional top, the rectilinear motion that promptly changes scanning becomes the shaped form motion, thereby saves the utilization of the finite space.And because the volume of curvilinear style scanner is less and easy to carry and it is simple to make, therefore, the present invention also can reach and use collection convenient and save the secondary objective of manufacturing cost.

In addition, the shaped form scanner can design special interlinked mechanism and drive optical sensor, therefore also can scan article with particular curve, particularly around the solid of this object, carry out scanning motion, remove in addition, the present invention also can reach many curvilinear style scannings of continuity and non-continuity.

Summary of the invention

Based on above goal of the invention and solve known shortcoming, save the space for reaching, use that collection is convenient, file, the successional shaped form article of scanning that can scan big specification and save under the preceding topic of purposes such as cost, special improvement project of the present invention proposed; The present invention is a kind of shaped form scanister, comprise a body housing, a curvilinear style file platform, be connected in this body housing, one be scanned object in order to place, a gear train is connected in a curvilinear style transmission shaft, and one the optical sensing module be that this curvilinear style transmission shaft drives, and this curvilinear style file platform is done the curvilinear style scanning motion, be positioned at the file of the file platform other end with scanning.

Wherein optimal way is, this optical sensing module also comprises a base, an optical sensor and a contact element in addition.

Optimal way is that this optical sensing module also comprises a flexible member, is arranged between this optical sensor and this base, utilizes the elastic force effect that the optical sensing module is slided along curvilinear style file platform closely.

Optimal way is, this contact element comprises a transparent cover and a saddle, makes this optical sensor can receive the light signal of scanning, and can be smooth-going slip over curvilinear style file platform.

Optimal way is, this saddle is a plurality of projectioies, and it extends from the glass top.

Optimal way is that this flexible member is a spring.

Another optimal way is that gear train of the present invention is a cam-type gear train, can make the optical sensing module do continuous curved surface scanning motion along a cam.

An optimal way is again, and gear train of the present invention is a piston rod formula gear train, can make this optical sensing module because of the mutual motion of a piston and a connecting rod and produce discrete curved surface scanning motion.
