In the existing hand held scanister, because rolling cylinder 31 can only be along the longitudinal movement, in other words, only can know scanister positional information longitudinally during scanning, the information of transverse direction (left and right directions of file) has no way of learning.Therefore during the prior art scanning document, need carry out repeatedly the scanning of longitudinal direction, above-mentioned repeatedly scanning inswept file extent lap must be arranged, and then connect assembly to rebuild whole file by software.
In addition, if the mistake of occurred level direction is offset, because existing scanister can't be learnt the information of horizontal direction, the result of mistake appears easily during scanning.
When connecing with software when piecing together scanning document, identical part in the essential image of differentiating twice scanning because the mistake skew of GTG (gray level) difference and horizontal direction, make connect piece together inaccurate or connect piece together difficult.
The purpose of this utility model is to provide a kind of hand held scanister of piecing together scanning document that need not connect.
Another purpose of the present utility model is to provide a kind of hand held scanister that computer mouse uses that can be used as.
The purpose of this utility model is achieved in that promptly provides a kind of hand held scanister, has lighting mechanism, the file at place, the described scanister of uniform irradiation place; The image reading mechanism is accepted the light of described lighting mechanism, reads the image on the file and converts thereof into electric signal; Travel mechanism, it moves described scanister operator's mat; Perception mechanism is connected in described travel mechanism, the position of perception scanister, and convert thereof into electric signal; Electronic mechanism is connected in described image reading mechanism and described perception mechanism, handle the electric signal from described image reading mechanism and described perception mechanism, and the data that will handle is received host computer through external communication device; Shell mechanism constitutes described scanister shell; Described travel mechanism moves freely described scanister to any position on the two dimensional surface of scanning document, described perception mechanism detects described scanister position on two dimensional surface.
The advantage of the utility model device is, its travel mechanism can make the operator the plane of scanning motion laterally with vertically all can move freely, perception mechanism can the perception scanister in any position of the above-mentioned plane of scanning motion, it does not need to connect the assembly scanning document, scanning is convenient, and quality of scanning is good.
Below in conjunction with accompanying drawing, the utility model embodiment is described, wherein:
Fig. 1 is the vertical view of the utility model hand held scanister;
Fig. 2 is the side view of the utility model hand held scanister;
Fig. 3 is the part of the utility model hand held scanister perception mechanism and the embodiment of travel mechanism;
Fig. 4 is an embodiment enlarged drawing shown in Fig. 3;
When Fig. 5 was mobile the utility model hand held scanister, its perception mechanism detected the displacement synoptic diagram of directions X and Y direction;
Fig. 6 is the vertical view of existing hand held scanister;
Fig. 7 is the side view of existing hand held scanister.
Fig. 1 and Fig. 2 represent the vertical view and the side view of the utility model hand held scanister respectively, and it comprises: lighting mechanism 0, and the file extent 1 at place, irradiation scanister place is with so that it has uniform illumination; Image reading mechanism, the light of accepting lighting mechanism 0 to be reading the image on the file, and convert thereof into electric signal; Travel mechanism is with so that the operator is convenient to the motion scan device; Perception mechanism is connected in travel mechanism, in order to the position of perception scanister, and converts thereof into electric signal; Electronic mechanism is connected in earlier figures as reading mechanism and perception mechanism, and in order to handle the electric signal from image reading mechanism and perception mechanism, the data that aforementioned processing is crossed is received host computer through external communication device again; And shell mechanism 6, constitute whole scanister shell.Travel mechanism of the present utility model can make the operator move freely scanister to any position on the two dimensional surface of desiring scanning document, and perception mechanism can detect the position of scanister at the two dimensional surface of file.
As scheme shown in the l, the embodiment of aforementioned travel mechanism comprises: a rolling ball 33, mat ball 33 roll on file and are convenient to move whole scanister; Two strong points 32 provide two points that contact with the desire scanning document, and the point that cooperates aforementioned ball 33 to contact with file forms a plane, and its purpose is to make scanister stably to move on file.
Aforementioned perception mechanism comprises horizontal perception mechanism and vertical perception mechanism, and Fig. 3 represents to feel mechanism's one preferred embodiment.Wherein laterally perception mechanism mainly comprises: contact cylinder 411, barrel surface is cut in the point 331 in the spherical travel mechanism 33, when spherical travel mechanism 33 rotated, contact cylinder 411 can be driven and be rotated, and its rotational angle size is proportional to the displacement of scanister along transverse direction; Slit disk 431, interlock has equally distributed slit in contact cylinder 411 on it; Sensor 441, be located at slit disk 431 1 sides, in order to detect the contact cylinder 411 the rotational angle size, thereby know the displacement of scanister along transverse direction, vertically perception mechanism is similar to horizontal perception mechanism, comprising: contact cylinder 412 (being cut in the point 332 on the ball 33); Slit disk 432; And sensor 442, its principle of work is with laterally perception mechanism is identical.
Above-mentioned contact cylinder 411 and 412 also respectively can be through gear set drive slit disk 431 and 432, and its benefit is to increase speed ratio.The relation of above-mentioned point 331, point 332 and 333 3 in the centre of sphere forms the angles of 90 degree as shown in Figure 4.
As shown in Figure 5, when mobile the utility model palm scanister, before supposing to represent to move with solid line and the dotted line respectively and position of moving the back scanister, and the position of scanister is (X0 before supposing to move, Y0), then move the back and moved (Δ X, Δ Y) respectively at directions X and Y direction because perception mechanism detects, be (X0+ Δ X, Y0+ Δ Y) so learn the position of moving the back scanister.
With reference to figure 1 and Fig. 2, the preferred embodiment of image reading mechanism comprises again: mirror 21, and in order to change the direct of travel that lighting mechanism 0 impinges upon file extent 1 formed light signal, the scope that light signal is advanced is limited to less space; Lens 22 are in order to dwindle optical imagery; Charge-coupled device (CCD) 23, acceptance converts thereof into electric signal, and then delivers to electronic mechanism through the optical image signal that lens 22 dwindle.And aforementioned lighting mechanism 0 also comprises light modulation portion, in order to regulate the brightness size as required.
In addition, the utility model hand held scanister also can use as computer mouse separately, as long as the function key of lighting mechanism and image reading mechanism is turned off.
In sum, the utility model hand held scanister, the travel mechanism that provides a kind of operator of making can on the two dimensional surface of scanning document, move freely this scanister, and this scanister of energy perception is in the perception mechanism of any position of the above-mentioned plane of scanning motion.This hand held scanister need not connect the file of piecing together scanning document and rebuilding scanning, facility simple to operate.In addition, the utility model device also can be made computer mouse and use, and only uses the Port of a computer can realize scanner and mouse function simultaneously.
