Description

The present invention relates to a scan module, particularly to a scan module that maintains scan quality when scanning paper.

See FIG. The conventional scanner 200'is provided with a paper feed transport path 10'that communicates with the outside, and the paper feed transport path 10'is connected to a horizontal paper scan transport path 20'for passing paper, and is connected to the paper scan transport path 20'. 20'is connected to the paper ejection transport path 30'. The bottom of the paper scan transport path 20'is the scan glass 50', and the brush 70 is provided on the upper side. When the scanner scans the paper, dust is accumulated in the scan glass 50'of the paper scan transport path 20', and the dust adheres due to the static electricity of the scan glass 50'. .. When the paper passes through the paper scan transport path 20', the paper is ejected along the scan glass 50' toward the paper discharge transport path 30'. However, the paper scan transport path 20'is a horizontal transport path, and when the paper passes through the paper scan transport path 20', the movement path becomes horizontal, so that it becomes difficult for the paper to come into close contact with the scan glass 50'. , Is discharged from the paper scan transport path 20'with only some dust. Moreover, since the remaining dust remains on the scan glass 50'due to static electricity, the brush 70 on the upper side of the paper scan transport path 20'is rotated during paper scanning to remove the dust on the scan glass 50'. Needs to be removed from 20'.

However, in such a dust removing method, the installation space for the internal parts of the scanner 200'is increased, and the motor for rotating the brush 70 must be further added. Therefore, the power consumption of the scanner 200'is increased as a whole. Volume and noise will increase.

Therefore, it is necessary to provide a scan module that saves space, reduces noise, and removes dust while reducing the number of internally required parts.

An object of the present invention is to provide a scan module that maintains scan quality when scanning paper.

In order to realize the above object, in the present invention, a scan module provided in the scanner, which is provided in front of the paper scan transport path and the paper scan transport path, and is connected to the paper scan transport path. It is erected on the upper side of the transport path and the paper scan transport path, and has a storage space inside. The opening of the accommodation space is higher on the side closer to the paper feed transport path than on the side far from the paper feed transport path. The fixed bracket that opens in an inclined state as described above, and the fixed bracket and the opening of the accommodation space that form an oblique transportation path when the paper scan transfer path faces substantially parallel to the opening of the accommodation space. A scan module is disclosed that includes a scan glass that is provided, covers the accommodation space, and exhibits an inclined state together with the paper scan transport path.

As described above, the scan glass is tilted together with the paper scan transport path, so that when the paper passes through the paper scan transport path, the tilted arrangement causes dust on the glass to be in close contact with the scan glass. Is discharged with. In this way, the scan quality of the scan module for the paper can be maintained by eliminating the need for extra cleaner parts and preventing dust from accumulating in the paper scan transport path.

It is a perspective view which shows how the scan module of this invention is attached to a scanner. It is sectional drawing of the line II-II of FIG. It is an enlarged view when the paper in the circle III in FIG. 2 enters the paper scan transport path. It is an enlarged view after the paper in the circle IV in FIG. 2 has entered the paper scan transport path. It is sectional drawing of the conventional scan module.

Hereinafter, the technical content, structure and features of the present invention, the purpose to be achieved, and the effect to be achieved will be described in detail with reference to the drawings with examples.

See FIGS. 1 and 2. In the present invention, the scan module 100 is disclosed, and the scan module 100 is provided in the scanner 200. The scan module 100 of the present invention scans the paper 300, and is provided with a paper feed transfer path 10 that communicates with the outside. In the present invention, the side on which the paper 300 is supplied is defined as the front side, and the side opposite to the side on which the paper 300 is supplied is defined as the rear side. Behind the paper feed transport path 10, a paper scan transport path 20 for passing the paper 300 connected to the paper feed transport path 10 is provided. Behind the paper scan transport path 20, a paper discharge transport path 30 connected to the paper scan transport path 20 is provided. The scan module 100 is provided with a scan glass 50.

The scan module 100 includes a fixing bracket 40 that extends laterally. The fixed bracket 40 has an accommodating space 41, and the opening of the accommodating space 41 opens in an inclined state, and the inclination is such that the side closer to the paper feed transport path 10 is higher than the side farther from the paper feed transport path 10. is there. The scan glass 50 is provided in the opening of the accommodation space 41 and covers the accommodation space 41. A plurality of light source generators 60 and a plurality of photoelectric sensors (not shown) are provided in the accommodation space 41. Since the plurality of light source generators 60 and the plurality of photoelectric sensors are both arranged perpendicular to the scan glass 50, the depth setting of the scanner can be maintained. Since the opening of the accommodation space 41 is provided unevenly on the paper feed transfer path 10, the scan glass 50 is in an inclined state, and the plurality of light source generators 60 and the plurality of photoelectric sensors are not parallel to the bottom surface of the scan module 100. It will be provided. Each of the plurality of light source generators 60 is for emitting a light source to the paper 300 of the paper scan transport path 20 via the scan glass 50, and the paper 300 is used for each of the plurality of photoelectric sensors via the scan glass 50. Reflect the light source. In this way, the paper 300 is scanned.

See FIGS. 3 and 4. When the scan module 100 of the present invention is used, dust 400 is generated in the paper scan transport path 20, and the dust 400 is generated on the scan glass 50 by static electricity caused by friction between the scan glass 50 and the paper. Adhere to. Since the scan glass 50 is in an inclined state, the paper scan transport path 20 between the scan glass 50 and the bottom surface of the scan module 100 is an oblique transport path that is inclined toward the rear lower side. Since the paper scan transport path 20 is an oblique transport path that is inclined toward the lower rear side, when the paper 300 enters the paper scan transport path 20 from the paper feed transport path 10, the front end of the paper scan transport path 20 comes first. By contacting the scan glass 50, which is the top surface of the paper, and controlling the movement path by the downward slope of the scan glass 50, the paper is discharged to the paper ejection transport path 30 while being in close contact with the scan glass 50. At this time, the dust 400 adheres between the scan glass 50 and the paper 300, and is discharged from the scan glass 50 as the paper 300 moves due to the frictional force generated by the paper 300 and the glass. By removing the dust 400 in the paper scan transport path 20 in this way, the scan quality of the scan module 100 for the paper 300 can be maintained.

As described above, the scan glass 50 is tilted together with the paper scan transport path 20, so that the paper 300 is in close contact with the scan glass 50 when passing through the paper scan transport path 20, and dust is present on the glass 50. Ejected with 400. In this way, the scan quality of the scan module 100 for the paper 300 can be maintained by eliminating the need for extra cleaner parts and preventing dust 400 from accumulating in the paper scan transport path 20.
