Embodiment
Below with specific embodiment, each form content that the utility model is disclosed is described in detail.
Referring to Fig. 2, describe scanner of the present utility model in detail.Similarly, scanner of the present utility model also has housing, and all devices and the assembly that constitute scanner are to be arranged in the housing, will not give unnecessary details.Fig. 2 shows scanner internal structure three-dimensional exploded view of the present utility model, and scanner of the present utility model comprises transparency cover 23, sensing apparatus, elastic component 25 and sliding component 27.In the present embodiment, sensing apparatus comprises bearing assembly 24 and image sensor (showing on the figure), and image sensor be contact image sensor (Contact Image Sensor, CIS).
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, and inside is provided with image sensor, and image sensor scans across 23 pairs of objects of transparency cover.Connecting portion 241 and pivot 242 are arranged at bearing assembly 24 bottoms, and the belt 261 of drive unit 26 is connected with the connecting portion 241 of bearing assembly 24, so drive unit 26 can drive bearing assembly 24.Sliding component 27 has flat body 271, two 272,272 and two flanges 273,273 of lug, two lugs the 272, the 272nd are extended by two sides of body 271, and also being two sides by body 271, extend two flanges 273,273, the direction of two flange 273,273 extensions is opposite with the direction that two lugs 272,272 extend, one hole 274 is arranged on each lug 272, and the pivot 242 of above-mentioned bearing assembly 24 passes hole 274 to articulate bearing assembly 24 and sliding component 27.And in the present embodiment, elastic component 25 is a long strip type shell fragment, and two flanges 273,273 of sliding component 27 just clamp the dual-side of elastic component 25.
Scanner of the present utility model is via after the above-mentioned assembling, elastic force by elastic component 25, can make sliding component 27 promote that bearing assemblies 24 are replaced, closely connected transparency cover 23, the distance that image sensor in the bearing assembly 24 just can be maintained fixed with object, so guarantee to as if be positioned on the focal length of image sensor.Simultaneously, bearing assembly 24 can move along elastic component 25 by the driving of drive unit 26, makes image sensor can scan whole object.
Please cooperate again referring to Fig. 3 a, Fig. 3 b and Fig. 3 c, Fig. 3 a shows the synoptic diagram when bearing assembly 24 is connected with elastic component 25, the unassembled transparency cover 23 of this fashion, so elastic component 25 is not out of shape, the upper surface of bearing assembly 24 is to be higher than the position that transparency cover 23 is about to assemblings.Again, also being provided with contact member 244 on bearing assembly 24, for example is a wear-resistant gasket, and bearing assembly 24 contacts with transparency cover 23 by contact member 244.Fig. 3 b shows after transparency cover 23 assemblings, bearing assembly 24 by transparency cover 23 to lower compression, the position of elastic component 25 drops to solid line position by the dotted line position on the figure, that is to say, elastic component 25 produces distortion because of pressing down of transparency cover 23, thereby producing a recovery elastic force that makes progress, the utility model is by this recovery elastic force, forces bearing assembly 24 replacing transparency cover 23.See also Fig. 3 c again, after showing that assembling is finished, transparency cover 23 is uneven state with elastic component 25, and the sliding component 27 between bearing assembly 24 and the elastic component 25, passed the hole 274 of sliding component 27 and articulated by the pivot 242 of bearing assembly 24, therefore the recovery elastic force that just can utilize elastic component 25 to be produced still can contact bearing assembly 24 with transparency cover 23 keeping parallelisms.Thus, scanner of the present utility model just can make bearing assembly 24 closely connected in transparency cover 23 in whole scanning process, makes the position of object be positioned on the focal length of image sensor, to guarantee the optical quality of scanner.Again by the driving of drive unit 26, bearing assembly 24 is moved along elastic component 25 afterwards, make image sensor can finish scanning sequence.
