It should be noted that in the drawing of the present application, the direction of arrow Y meaning is that original copy 1 is passed by contact type image
Direction of motion when sensor.Original copy 1 is the coin with relief pattern in embodiments herein, wherein such as Fig. 1 and Fig. 2
Shown, the recessed face of original copy 1 is 1a, projecting surface 1b.
Be specifically described below contact-type image sensor 200 provided by the present application compared with the prior art in contact figure
As sensor can more effectively obtain the working principle of the relief pattern information on original copy 1.
Fig. 1 shows the structure of contact-type image sensor in the prior art, and is shown in detail concave-convex to having
The working principle when original copy 1 of pattern is scanned；Specifically, as shown in Figure 1, contact type image in the prior art senses
Device includes illuminating source 20 ', lens 30 ', (the i.e. photosensitive integrated electricity of photographic department 42 ' for being used for the converged light of receiving lens 30 '
Road), the sensor base plate 41 ' that carries the light sensitive integrated devices being arranged in a straight line, accommodate illuminating source 20 ', be lens 30 ', photosensitive
The light-transmitting plate 50 ' that is used to carry original copy 1 of the frame 10 ' and setting of portion 42 ' and sensor base plate 41 ' on frame 10 '；Its
In, the lens 30 ' of contact-type image sensor in the prior art are arranged along the vertical direction, i.e., the axis of lens 30 ' perpendicular to
The plane of scanning motion of original copy 1.
As shown in Figure 1, the principle of existing contact-type image sensor scan image is, the light that illuminating source 20 ' issues
Line is irradiated on original copy 1, and light is scattered or is reflected into lens 30 ' by original copy 1, is converged on photographic department 42 ' through lens 30 ',
To convert optical signals into electric signal, the scan image of original copy 1 is obtained after subsequent processing, during the scanning process, 1 meeting of original copy
It is moved along Y-direction.01 ', 02 ', 03 ' in Fig. 1 is respectively three light issued along the main optical path of illuminating source 20 ', point
It is not irradiated on 3 points of A, B, C of original copy 1.M, n is respectively the axis for scanning the lens 30 ' when arriving A, B two o'clock and C point.From Fig. 1
In as can be seen that when contact-type image sensor scanning is to D point, the point position C of original copy 1, due to the key light of illuminating source 20 '
Road favours the plane of scanning motion of original copy 1, and the light that direct irradiation enters in D point to the region of E point on original copy 1 is seldom, therefore, D
There will be biggish luminance difference between point and C point (C point brightness is apparently higher than D point).And contact-type image sensor scans
To original copy 1 in A point and the point position B, the light of A point and B point scattering all some can along lens 30 ' axis into
Enter lens 30 ', therefore, does not just have apparent luminance difference between point A point and B point.It follows that using existing contact
Imaging sensor is scanned the original copy 1 with relief pattern, cannot effectively scan the concave portion and protrusion of original copy 1
Profile between part, therefore, existing contact-type image sensor can not obtain the complete relief pattern information of original copy 1,
And then it is unable to reach the ideal scan effect to the original copy 1 with relief pattern, being unable to satisfy false distinguishing or identification to original copy 1 needs
It asks.

Show the working principle when being scanned to the original copy 1 with relief pattern；Specifically, as shown in Fig. 2, the application
Contact-type image sensor 200 is that lens 30 are configured to greatest improvement of the existing contact-type image sensor in structure
It favours horizontal plane and is tilted towards 20 side of light-source structure；I.e. the plane of scanning motion of the axis 31 of lens 30 and original copy 1 hangs down in non-
Straight angled relationships.
As shown in Fig. 2, 01,02,03 in figure is respectively three light issued along the main optical path of light-source structure 20, point
It is not irradiated on 3 points of A, B, C of original copy 1.When D point, the point position C of the scanning of contact-type image sensor 200 to original copy 1, by
The plane of scanning motion of original copy 1 is favoured in the main optical path of light-source structure 20, direct irradiation enters in D point to the region of E point on original copy 1
Light it is seldom, therefore, will there is biggish luminance difference between D point and C point (C point brightness is apparently higher than D point).And it contacts
Formula imaging sensor 200 scans postponing in A point and B point to original copy 1, each point in A point to the region of F point on original copy 1
The light of scattering or reflection largely cannot be introduced into lens 30, and the light through reflecting or scattering at B point largely enters lens
30, therefore, between A point and B point can also there be biggish luminance difference (B point brightness is apparently higher than A point)；And D point and C point and
It is exactly the profile between the concave portion and protrusion minute on original copy 1, i.e. recessed face 1a and projecting surface at the position of A point and B point
Contour line between 1b, thus can have apparent luminance difference between recessed face 1a and projecting surface 1b, it is therefore, provided by the present application
Contact-type image sensor 200 can effectively obtain the complete relief pattern information of original copy 1, and then reach with bump maps
The ideal scan effect of the original copy 1 of case meets false distinguishing and identification demand to original copy 1.
In order to facilitate the setting of lens 30, and contact-type image sensor 200 is made to distinguish the concave-convex sense of original copy 1 and obtain
Relief pattern information is taken, and then reaches the false distinguishing and identification requirement met to the ideal detection effect of original copy 1 to original copy 1.It is optional
, the angle between the axis 31 and horizontal plane of lens 30 is more than or equal to 10 degree and is less than or equal to 80 degree.
As shown in Fig. 2, photosensitive unit 40 includes sensor base plate 41 and the sensitive chip being arranged on sensor base plate 41
42, sensitive chip 42 is for converting optical signals to electric signal and obtaining the relief pattern information on original copy 1.
