Embodiment
The first embodiment of the present invention is please consulted Fig. 2 A and Fig. 2 B simultaneously, image read-out 3 of the present invention includes scan module 30 and light-shielding mechanism 31 at least shown in the figure, wherein the structure of scan module 30 is identical with the scan module 15 (in Fig. 1) of conventional images reading device 1, comprises light source 301, image sensing element 302, catoptron 303 and amasthenic lens 304 etc. at least; And light-shielding mechanism 31 is the devices that can move vertically for, and the user can move light-shielding mechanism 31 by the mode of pulling easily, pressing or reverse vertically, covers this light or does not cover this light with switching; Details are as follows for the principle of work of image read-out 3:
When image read-out 3 of the present invention during in standby, scan module 30 can be by the drive of a driving mechanism (not shown), move to a default position of readiness, be the position of scan module 30 shown in Fig. 2 A, the light that the light source 301 of scan module 30 is produced, the energy direct irradiation is in light-shielding mechanism 31, and light-shielding mechanism 31 generally can select for use white lighttight material to make, so the time light via light-shielding mechanism 31 reflection after, produce an optical imagery, via a plurality of catoptron 303 reflections, focus on by amasthenic lens 304 again, learn image earlier and be convenient to imaging on the image sensing element 302, image sensing element 302 is transformed into a simulating signal with the optical imagery of institute's sensing, the simulating signal 310 on the left side of this simulating signal such as Fig. 3 A and Fig. 3 B; When user's desire startup image read-out 3 scans, can be by the mode of directly pulling easily, pressing or reverse, make light-shielding mechanism 31 move to B position among Fig. 2 B by the A position among Fig. 2 A, at this moment, because light-shielding mechanism 31 is when the B position, can it can't be moved on shield lights, image sensing element 302 in the scan module 30 just sensing less than any optical imagery, therefore export another simulating signal, the simulating signal 311 on the right of this simulating signal such as Fig. 3 A and Fig. 3 B; Image read-out 3 is just based on the difference of image sensing element 302 gained simulating signals, directly start a default action, as start driving mechanism (not shown) driven sweep module 30 and scan, or startup software driver, after allowing the user set some parameter values, restart scanning, thereby reach the purpose of user's scanning document.
The second embodiment of the present invention is please consulted Fig. 4 A and Fig. 4 B simultaneously, the principle of present embodiment is all identical with first embodiment with original paper, the position of different is light-shielding mechanism 41 is the C positions that are arranged in Fig. 4 A, light-shielding mechanism 41 is pulling through the user, after pressing or reversing, the position that makes light-shielding mechanism 41 is moved to D position among Fig. 4 B by the C position among Fig. 4 A, at this moment, because light-shielding mechanism 41 is when the D position, can it can't be moved on shield lights equally, image sensing element 302 in the scan module 30 also sensing less than any optical imagery, produce the effect identical with first embodiment, image read-out 3 is similarly based on the difference of image sensing element 302 gained simulating signals, directly start a default action, as start driving mechanism (not shown) driven sweep module 30 and scan, or start software driver, allow the user set some parameter values after, restart scanning, thereby reach the purpose of user's scanning document.
The third embodiment of the present invention is please consulted Fig. 5 A and Fig. 5 B simultaneously, the principle of present embodiment is all identical with second embodiment with original paper, the position of different is light-shielding mechanism 41 is arranged in the E position of Fig. 5 A, light-shielding mechanism 41 is pulling through the user, after pressing or reversing, to make light-shielding mechanism 41 move to F position among Fig. 5 B in rotary manner by the E position among Fig. 5 A, at this moment, because light-shielding mechanism 41 is when the F position, can it can't be moved on shield lights equally, reach the effect identical with second embodiment, image read-out 3 is similarly based on the difference of image sensing element 302 gained simulating signals, directly start a default action, as start driving mechanism (not shown) driven sweep module 30 and scan, or startup software driver, after allowing the user set some parameter values, restart scanning, thereby reach the purpose of user's scanning document.
Among above-mentioned each embodiment, its principle all is to make scan module in the image read-out when standby, move to a default position of readiness, the user utilizes the mode of pulling, pressing or reverse then, make light-shielding mechanism energy shield lights, light can't be entered in the image sensing element in the image read-out, the simulating signal that causes image sensing element to produce has tangible change, carry out a default action thereby start image read-out, reach the purpose of user's scanning document; Certainly, if scan module is when standby, Schilling light-shielding mechanism is with light-shielding, allow the user move light-shielding mechanism again, make light can reenter image sensing element, and the simulating signal that makes generation has tangible change, and is just opposite with the aforesaid way program, also can reach the effect that starts an action of presetting; So, image read-out of the present invention can save when wanting to reach identical purpose in existing, the object cost (as button, button base plate and signal line or the like) that must bear, moreover, more can save the time cost of the above-mentioned object of assembling, also make the image read-out weight can be lighter.
According to above-mentioned conception, embodiments of the invention can also provide several different light-shielding mechanisms, can cover the light of different sections respectively, make image read-out can start different deliberate action respectively, as scanning, fax, xerox or conduct electricity sub-mail or the like; Its principle is described below:
See also Fig. 6, this figure is an image sensing element principle of work synoptic diagram, after an object 6 to be scanned reflects (not shown) through light shown in the figure, after focusing on by amasthenic lens 304 again, can imaging on image sensing element 302, wherein image sensing element 302 is by a plurality of sensor pixel a1, a2, a3, a4, a5, an forms, and the directions X in Fig. 6 is arranged in line, can sense a plurality of section a1 ' in the object 6 to be scanned respectively, a2 ', a3 ', a4 ', a5 ', the image of an ', utilize above-mentioned principle, on the opticpath that the present invention can utilize certain some particular section to reflect light-shielding mechanism is set, for example: light-shielding mechanism can be arranged on the opticpath that section a1 '～a50 ' reflected, as zone 61, that is to say, when the zone in 61 the light-shielding mechanism action and during shield lights, will make sensor pixel a1～a50 sensing less than light, thereby drive a default action; Another group light-shielding mechanism also can be arranged on the opticpath that a51～a100 reflects, thereby drives another default action; By that analogy, by the light-shielding mechanism of diverse location is set respectively, can arrange respectively to drive different default actions, as scanning, fax, xerox or conduct electricity sub-mail or the like, to reach purpose of the present invention.
Abovely disclosed the present invention in conjunction with preferred embodiment; this embodiment only be used for the explanation but not in order to limit claim of the present invention; protection scope of the present invention is defined by following claim; all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
