Embodiment
Below with specific embodiment, each form content that the utility model is disclosed is described in detail.
Fig. 2 a and Fig. 2 b show the synoptic diagram of scanner of the present utility model, and as existing scanner, the device and the assembly that constitute scanner of the present utility model also all are arranged in the housing, will repeat no more.Scanner of the present utility model comprises transparency cover 23, sensing apparatus, guide rod 25 and base 27.In the present embodiment, sensing apparatus comprises image sensor 22 and bearing assembly 24, and image sensor 22 be contact image sensor (Contact Image Sensor, CIS).
Please the primary structure of scanner of the present utility model be described simultaneously referring to Fig. 2 a and Fig. 2 b.Can place object to be scanned (not showing on the figure, for example can be paper, photo etc.) on the transparency cover 23.Bearing assembly 24 is arranged on transparency cover 23 belows, inside is provided with image sensor 22, and image sensor 22 scans across 23 pairs of objects of transparency cover, simultaneously, bearing assembly 24 is provided with contact member 28 and contacts with transparency cover 23, and this contact member 28 can be a wear-resistant gasket.Base 27 is based on guide rod 25, and supporting bearing assembly 24 in relocatable mode, makes bearing assembly 24 replace transparency cover 23, and then makes the above-mentioned object of image sensor 22 scannings.
Above-mentioned base 27 comprises main body 271, float portion 272 and elastic component 273, and in the present embodiment, main body 271 is a sleeve, and float portion 272 is an arc plate, and elastic component 273 is an extension spring.Float portion 272 has two first connecting portions 274,274, be to be extended by the two edges of arc plate, and main body 271 has two second connecting portions 275,275, is to be extended by the outer peripheral edges of main body 271 both sides.Assembling is during base 27, and float portion 272 is arranged on body 271 inside haply, and strides and be located on the guide rod 25 that is fixed in the housing, but two first connecting portions the 274, the 274th protrude in outside the main body 271, and is corresponding with two second connecting portions 275,275 respectively.Connect the two groups of first relative connecting portions 274 and second connecting portion 275 by two elastic components 273,273 again, simultaneously, main body 271 is affixed with bearing assembly 24, has so far just finished the assembling of base 27.Therefore, from the above, the weight of image sensor 22, transparency cover 23 and bearing assembly 24 can be applied on the guide rod 25 via main body 271, elastic component 273 and float portion 272.
See also Fig. 3 a and Fig. 3 b again, it shows the cut-open view of scanner of the present utility model.Scanner of the present utility model before unassembled transparency cover 23 shown in Fig. 3 a, the weight of image sensor 22 and bearing assembly 24, put on the guide rod 25 via main body 271, elastic component 273 and the float portion 272 of base 27, in other words, guide rod 25 is to support image sensor 22 and bearing assembly 24 by base 27, at this moment, the top of the contact member 28 of bearing assembly 24 is to be higher than the position that transparency cover 23 is about to assembling.
Therefore, when transparency cover 23 shown in the arrow among Fig. 3 a and when assembling, see also Fig. 3 b, transparency cover 23 will compress the contact member 28 of bearing assembly 24, then the main body 271 of bearing assembly 24 pushing bases 27 moves down, because this moment, float portion 272 was the guide rods 25 that reclining, and guide rod 25 is fixing, therefore, to force elastic component 273 to be stretched and produce elastic deformation of aforementioned body 271 to bottom offset, that is to say, make elastic component 273 have elastic restoring force by assembling transparency cover 23, at this moment, the elastic restoring force of elastic component 273 will spur second connecting portion 275 and move up, be that main body 271 will make bearing assembly 24 can replace transparency cover 23 to top offset.Thus, scanner of the present utility model just can make bearing assembly 24 closely connected transparency cover 23 in whole scanning process, make that the position of object is to be positioned on the focal length of image sensor, to guarantee the optical quality of scanner, drive bearing assembly 24 by drive unit 26 more afterwards, the float portion 272 that bearing assembly 24 just drives base 27 moves axially along guide rod 25, makes image sensor 22 can finish scanning sequence.
