Description

Scanner

Technical field

The invention relates to a kind of scanner, and particularly relevant for a kind of scanner with curved printing opacity loading end.

Background technology

In the middle of numerous peripheries of PC, scanner one of the basic outfit of can saying so.

Please refer to Fig. 1, it illustrates is the structural representation of traditional scanner.Traditional scanner 100 mainly has printing opacity load plane 110 (being parallel to the X-Y plane shown in the diagram), ray machine 120 and guide member 130.120 of ray machines have radiation source 140.

File to be scanned (not showing among the figure) is placed on the printing opacity load plane 110.In the process that scanning is carried out, the radiation source 140 on the ray machine 120 is in order to launch an irradiates light 150, to be used for shining the file to be scanned that is placed on the printing opacity load plane 110.Then by guide member 130 guidings, the direction of the scanning direction Y shown in the diagram of edge moves ray machine 120, to scan file to be scanned.

The area of printing opacity load plane 110 must equal the area (for example being the area of A4) of file to be scanned at least.Therefore, the projected area of scanner 100 on X-Y plane just must equal the area of file to be scanned at least.And though paper feed type scanning device shared area on X-Y plane can come for a short time by general scanner, the paper feed type scanning device can only scan paper and can't scan books.

On the other hand, the ray machine 120 of scanner 100 needs to be moved by guide member 130 guidings, so need dispose guide member 130 in the scanner 100; And, CCD plate (not showing among the figure) in the ray machine 120 and the distance that is fixed between motherboard (not showing among the figure) in the scanner 100 are fixing because of moving of work ray machine 120, former needs use one transmission lines comes the signal between transmission of CCD plate and motherboard, therefore except being easy to generate the problem of EMI, also having the too much problem of connector number and produce.

By above as can be known, traditional scanner, the shortcoming that is had is:

One, scanner body projected area in the plane is excessive, causes the waste of the plane space of putting scanner.

Two, transmission line causes the problem of EMI, the inferior quality of scan-image.

Three, need use guide member, transmission line and more connector, therefore required cost is higher.

Summary of the invention

Purpose of the present invention is providing a kind of scanner exactly, and purpose is as follows:

The plane space that the scanner body is occupied is effectively dwindled, the quality of scanner scans image is able to cost preferable, scanner and is minimized.

According to above-mentioned purpose, the present invention proposes a kind of scanner, is summarized as follows with regard to its architectural feature now:

A kind of scanner, in order to scan file to be scanned, this scanner comprises at least: printing opacity loading end and rotation ray machine.The printing opacity loading end is to be curved surface, and the printing opacity loading end is to be disposed on the scanner, in order to put file to be scanned; The rotation ray machine then is disposed in the scanner, and is to be placed in file to be scanned on the printing opacity loading end with scanning around pivot rotation.Wherein, the rotation ray machine is to be driven and rotated by an actuator, and this actuator then can be a stepper motor.

A kind of scanner, in order to scan a file to be scanned, this scanner comprises at least:

One printing opacity loading end is a curved surface, and this printing opacity loading end is disposed on this scanner, in order to put this file to be scanned; And

One rotation ray machine is disposed in this scanner, and this rotation ray machine is to rotate this file to be scanned that is placed in scanning on this printing opacity loading end around a pivot.

Described scanner, wherein this rotation ray machine is to be driven and rotated by an actuator.

Described scanner, wherein this actuator is a stepper motor.

For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below.

Description of drawings

It is the structural representation of traditional scanner that Fig. 1 illustrates;

It is structural representation according to the scanner of preferred embodiment of the present invention that Fig. 2 illustrates.

Embodiment

Scanner provided by the present invention is that printing opacity load plane with traditional scanner changes with printing opacity carrying curved surface and replaces, and will portable originally ray machine to change be the ray machine of a rotary type that rotates around fixed axis.

Please refer to Fig. 2, it illustrates is structural representation according to the scanner of preferred embodiment of the present invention.Scanner 200 of the present invention is in order to scanning a file to be scanned, and scanner 200 comprises at least: printing opacity carrying curved surface 210 and rotation ray machine 220.220 of ray machines of rotation have a radiation source 240.

Printing opacity carrying curved surface 210 is disposed on the scanner 200, is used for putting file to be scanned (not showing among the figure).220 of ray machines of rotation are disposed in the scanner 200, and be around with diagram in 250 rotations of the equidirectional pivot of directions X.In this simultaneously, radiation source 240 emission irradiates lights 260 are placed in file to be scanned on the printing opacity carrying curved surface 210 with scanning on file to be scanned.

Wherein, rotation ray machine 220 can and rotate by actuator driving, and this actuator then can be a stepper motor.

Scanner 200 is in the process of scanning file to be scanned, and the light path of irradiates light 260 can turn to different scanning areas along with rotation ray machine 220, and coup to some extent.Because it is known that printing opacity carrying curved surface 210 is at the beginning of design, thus the change in optical path length of irradiates light 260 just can add by the angle variation of rotation ray machine 220 rotations in the hope of.After the variation of light path is tried to achieve, can correspond to a focal length Adjustment System that is arranged in the scanner 200 again and adjust focal length, and make the image quality of the file to be scanned that scanner 200 is scanned, can not change to some extent and not good because of the light path of irradiates light 260.

Scanner 200 is for a curved surface (printing opacity carrying curved surface 210), so the projected area of printing opacity load plane is come for a short time in the scanner 100 that the projected area on X-Y plane can be more traditional in order to the printing opacity loading end of putting file to be scanned.So the plane space that scanner 200 is occupied just can than scanner 100 occupied less, and can reach the purpose of saving placing space.

And rotation ray machine 220, except for being design in response to printing opacity carrying curved surface 210 designs, be for not moving also in addition because of it, so in scanner 200, extra guide member need be set, and the CCD plate in it be set and be arranged between motherboard in the scanner 200 and do not need to be provided with again a transmission line yet with transmission signals function.The expense that the benefit of transmission line then is to save transmission line and connector etc. need not be set, can reduce the cost of scanner.And there is not transmission line also can effectively avoid EMI to produce the problem that makes the scan-image bad.

Therefore, the disclosed scanner of the above embodiment of the present invention, the advantage that has is:

One, scanner body projected area in the plane can be less, the unlikely waste that causes the plane space of putting scanner.

Two, there is not transmission line, so can not cause EMI to produce the problem of the bad of scan-image.

Three, need not use guide member, transmission line and many connectors, therefore the required cost that expends can reduce.

In sum, though the present invention discloses as above with embodiment, so it is not in order to limit the present invention.
