Abstract

A scanner includes a groove and an automatic paper feeder. The groove is arranged on the side of the scanner. The automatic paper feeder is provided with a hook and a force-applying part, the hook is used to buckle with the groove so that the automatic paper feeder and the scanner are combined, and applying force on the force-applying part can make the automatic paper feeder and the scanner separate. The scanner may also include a guide slope, which is arranged above the groove, and the hook can be buckled with the groove through the guide slope.

Description

The fixture of automatic paper feeder

Technical field

The present invention relates to a kind of fixture of automatic paper feeder, particularly relate to a kind of fixture that is applied to the automatic paper feeder in the scanner.

Background technology

Scanner is a kind of device of pick-up image, in order to scanned photograph, literal page or leaf, figure and artistic illustration etc., even three-dimensional objects such as coin or textile, and convert it to the number format that computer can show, edits, stores and export.The work that scanner can be finished is very many, for example: hereof in conjunction with fine arts figure and photo; Textual scan is input in the document process software, saves the time of typewriting again; Fax paper scanning is input in database or the document process software stores; In multimedia, add active lively image; The data of integrating image in bulletin makes it can more effectively express theme etc.

Numerous advantages make scanner for general PC user or company's row number, become integral peripheral equipment.And the example wherein especially of the paper feed type scanning device with automatic paper feeder.Automatic paper feeder not only makes paper to be scanned be able to be admitted to automatically and easily on the scanning platform of scanner, and the speed of scanner scans file is out of shape fast.

The operation principle of paper feed type scanning device is, by being disposed at automatic paper feeder on the scanner with file feed-in scanner platform to be scanned.Then by relatively moving between file to be scanned and the optical module, light source in the optical module is emitted beam be radiated on the file to be scanned and reflective light.Receive this reflected light signal by optical module more afterwards, converting signal of telecommunication processing to, to finish scanning work.

Generally speaking, optical length has decisive influence for the quality of scan-image.And the distance between file to be scanned and the optical module (being the depth of field) is relevant with optical length again.Therefore, how to make the depth of field become a suitable and changeless value, so that scan-image has best quality, just becoming the paper feed type scanning device needs the urgent problem that solves most.And between automatic paper feeder and the scanner if a kind of preferable fixed form that couples is arranged, just can make to have a suitable and constant depth of field between file to be scanned and optical module.

Summary of the invention

The object of the present invention is to provide a kind of fixture of automatic paper feeder, to reach purpose with a suitable and changeless depth of field.

According to purpose of the present invention, a kind of fixture of automatic paper feeder is proposed.Wherein, arrangements of grooves is in the side of scanner.The side of automatic paper feeder then disposes trip and force section, this trip in order to the groove snapping, so that automatic paper feeder is able to combine with scanner, forces in the force section the trip on the automatic paper feeder side and the snapping of the groove on the scanner side are opened.This scanner also can include the guide ramp on the side that is disposed at scanner, and this guide ramp is disposed at the top of groove, and trip can be interlockingly connected by guide ramp and groove.

Description of drawings

Figure 1A is held on the stereogram of scanner for the automatic paper feeder of preferred embodiment of the present invention;

The generalized section that Figure 1B separates with scanner for the automatic paper feeder corresponding to Figure 1A;

Fig. 1 C is the schematic diagram behind trip and the groove snapping;

Fig. 1 D forces in the force section can make trip break away from the schematic diagram of groove.

Embodiment

The fixture of automatic paper feeder provided by the present invention utilizes the trip snapping be disposed on the automatic paper feeder to be disposed at groove on the scanner, so that automatic paper feeder can effectively be fixed on the scanner.And therefore plant fixed form, and can obtain a suitable and changeless depth of field, to improve the scanning quality of scan-image.

Please refer to Figure 1A, what it illustrated is the stereogram that is held on scanner according to the automatic paper feeder of preferred embodiment of the present invention.The both sides of automatic paper feeder 100 have trip 110 and force section 120.The both sides of scanner 130 then have guide ramp 140 and groove 150.

Automatic paper feeder 100 and scanner 130 original states for separating.Automatic paper feeder 100 combines by pushing automatic paper feeder 100 with scanner 130, makes trip 110 be able to descend along the guide ramp 140 with angle of inclination, and is interlockingly connected with the groove 150 that is positioned at guide ramp 140 belows and combines.

In the process that guide ramp 140 moves down, trip 110 is along with to the increase of bottom offset and strutted gradually a little at trip 110.Treat that trip 110 slides onto groove 150 places, trip 110 promptly fastens groove 150 securely, and makes that automatic paper feeder 100 and scanner 130 are combined.

Force section 120 on the automatic paper feeder 100 has the function that makes automatic paper feeder 100 disengaging scanners 130.That is, the application of force is pushed force section 120, can make trip 110 be able to be strutted by the application of force.Trip 100 after being strutted by the application of force is because no longer be subjected to the restriction constraint of groove 150, and then can make automatic paper feeder 100 self-scanning devices 130 on breaking away from if the application of force is upwards mentioned automatic paper feeder 100 again this moment.

Please refer to Figure 1B, it illustrated is the generalized section that the automatic paper feeder corresponding to Figure 1A separates with scanner.The trip 110 that automatic paper feeder 100 is had is to be interlockingly connected by the groove 150 of guide ramp 140 with scanner 130, to reach the purpose that automatic paper feeder 100 combines with scanner 130.

Illustrate the schematic diagram behind trip 110 and groove 150 snappings among Fig. 1 C, Fig. 1 D then illustrates and executes an application of force F and 120 can make trip 110 break away from the schematic diagram of grooves 150 in the force section.

In the above-mentioned preferred embodiment, the structure that guide ramp 140 and groove 150 all can be formed in one with scanner 130.The structure that trip 110 then can be formed in one with automatic paper feeder 100.

The position of groove 150 is to be fixed on the scanner 130 and can not change.Therefore, as long as trip 110 is lived with groove 150 snappings, the relative position that automatic paper feeder 100 and scanner are 130 can be determined and can not change.So the depth of field between between file to be scanned (not showing among the figure) and optical module (not showing among the figure) can be fixed motionless.And, can establish each file to be scanned of 100 feed-ins of automatic paper feeder that is if this depth of field is the suitable depth of field, the scan-image that is scanned for scanner 130 all can have best scanning quality.

The fixture of the disclosed automatic paper feeder of the above embodiment of the present invention is applied in the scanner, and its advantage has a suitable and constant depth of field for making between file to be scanned and optical module.In view of the above, scanner can scan the scan-image of image quality the best according to the file to be scanned of automatic paper feeder institute feed-in.

In sum; disclosed the present invention in conjunction with an above preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention; can be used for a variety of modifications and variations, so protection scope of the present invention should be with being as the criterion that claims were defined.
