Abstract
The present invention relates to a scanning device, including a shell body, its upper portion possesses a transparent platform for placing file to be scanned, a guide screw fixed in the shell body and arranged according to forward and backward direction, a scanning module positioned on the guide screw, a gear device placed on the guide screw, its inner side at least possesses a convex tooth for interaction with guide screw and a motor positioned at one side of gear device for forward and backward driving said gear device and making it move synchronously. When the gear device is drive by the motor, the convex tooth can be moved on the guide screw to make the gear device forward and backward move along the guide screw to drive scanning module to scan the file positioned in shell body.
Description
The invention provides a kind of scanister, refer to a kind of scanister that is provided with lead screw especially.
Along with soft, hardware development of technology, scanner is being played the part of very important role in the input of figure and picture.In various scanners, platform-type scanner is the most frequently used a kind of scanner.In platform-type scanner, to be the below that is installed on a transparent platform in the mode that can spur back and forth place file on the transparent platform with scanning to scanning module.Because scanning module itself does not have any power, therefore need by gear train, the strap lug or the cable wire that for example are installed on a plurality of circle wheels are kept the balance on its horizontal direction, the direction of glue file scanning, and drive back and forth is with the file on the scanning transparent platform.The structure of these gear trains is all very complicated usually, waste time and energy very much in system assembles and maintenance, and strap lug or cable wire can't firmly maintain scanning module on one trapped orbit.In addition, motor generally is used for drive transmission device, makes gear train drive scanning module, therefore very expends electric power.
Therefore, fundamental purpose of the present invention is to provide a kind of scanister, be provided with a lead screw simplifying the structure of gear train, and make scanning module be able to move forward and backward by the motor driven scanning module to reduce power consumption, to address the above problem along lead screw.
For achieving the above object, the invention provides a kind of scanner, wherein include: a housing, its top is provided with a transparent platform and is used for placing file to be scanned; The lead screw that one fore-and-aft direction is provided with is fixed in the described housing, and the surface of described lead screw is provided with a ring shaped thread; The one scan module is located on the described lead screw, is used for moving forward and backward to scan described file along described lead screw; One toothed gearing is located on the described lead screw, and its inboard is provided with at least one double wedge, be used for described lead screw on ring shaped thread act on mutually; And a motor, be located at a side of described toothed gearing, drive before and after being used for described toothed gearing and with the same moved further of described toothed gearing; Wherein when the described toothed gearing of described motor driven, the double wedge of described toothed gearing can move along the ring shaped thread on this lead screw so that described toothed gearing is able to move forward and backward along described lead screw, and described toothed gearing can be in promoting described scanning module on the described lead screw so that described scanning module scans described file before and after being able in described housing.
Fig. 1 is the synoptic diagram of scanner of the present invention.
Fig. 2 is that the scanning module in Fig. 1 scanner is socketed on the synoptic diagram on the lead screw.
Fig. 3 is that the toothed gearing in Fig. 1 scanner is socketed on the synoptic diagram on the lead screw.
Fig. 4 is the element figure of Fig. 3 toothed gearing.
Fig. 5 is the synoptic diagram of the gear pressing plate of Fig. 4 toothed gearing.
Consult Fig. 1 and Fig. 3.Fig. 1 is the synoptic diagram of scanner 10 of the present invention, and Fig. 2 is that the scanning module 12 in the scanner 10 are socketed on the synoptic diagram on the lead screw 14, and Fig. 3 is that the toothed gearing 16 of scanner 10 is socketed on the synoptic diagram on the lead screw 14.
As shown in Figure 1 to Figure 3, scanner 10 includes a housing 18, its top is provided with a transparent platform 20 and is used for placing file to be scanned 22, the lead screw 14 of one fore-and-aft direction setting is fixed in the housing 18, one scan module 12 is located on the lead screw 14 to move forward and backward with scanning document 22 along lead screw 14, one toothed gearing 16 is located on the lead screw 14, and a motor 24 is located at a side of toothed gearing 16, before and after being used for drive gear arrangement 16 and with toothed gearing 16 same moved further.
See also Fig. 4 and Fig. 5, Fig. 4 is the element figure of toothed gearing 16, and Fig. 5 is the synoptic diagram of the gear pressing plate 28 of toothed gearing 16.Toothed gearing 16 includes teeth parts 26, one gear pressing plates 28 and a gear lining 30, is used for teeth parts 26 and gear pressing plate 28 are incorporated on the lead screw 14.The surface of lead screw 14 is provided with a ring shaped thread 34, and the inner surface of gear pressing plate 28 is provided with two double wedges 32, be used for lead screw 14 on ring shaped thread 34 act on mutually, and motor 24 contacts drive gear arrangement 16 with teeth parts 26.
When motor 24 drive gear arrangement 16, double wedge 32 on the inner surface of gear pressing plate 28 can move so that toothed gearing 16 is able to move forward and backward along lead screw 14 along the ring shaped thread 34 on the lead screw 14, and toothed gearing 16 can be in promoting scanning module 12 on the lead screw 14 so that scanning module 12 be able to front and back scanning document 22 in housing 18.
Within the scope of the invention, two double wedges 32 of the inner surface of gear pressing plate 28 can be replaced by a double wedge or most double wedges, even these a plurality of double wedges one-tenth one ring shaped thread capable of being combined, the ring shaped thread 34 that it corresponds on the lead screw 14 is used for acting on mutually with the lip-deep ring shaped thread 34 of lead screw 14.In addition, lead screw 14, toothed gearing 16 and motor 24 not only can be located at an end of scanning module 12 as Fig. 2, also can be located at middle part or other positions of scanning module 12, as long as can front and back driven sweep module 12.
Compared to known scanner, the scanning module 12 of scanner 10 of the present invention moves forward and backward along lead screw 14, so scanning module 12 very firmly moves in housing 18.And because 24 device driven of motor are toothed gearings 16, but not lead screw 14, so the electric power of motor 24 required supplies is very limited.
Though above in conjunction with the accompanying drawings detailed description has been made in a preferred embodiment of the present invention; but those of ordinary skill in the art is appreciated that; in the present invention conceives scope; can also make multiple variation and remodeling to this embodiment; will be understood that these variations and remodeling all will drop in the protection domain of appended book qualification.
