Description

Scanning module

Technical Field

The utility model relates to a scanning module especially relates to a can be when the paper scans, maintain scanning module of scanning quality.

Background

Referring to fig. 5, the conventional scanner 200 'has a paper feeding path 10' communicating with the outside, the paper feeding path 10 'is connected to a horizontal scanning path 20' for passing paper, and the scanning path 20 'is connected to a paper discharging path 30'. The bottom of the scanning channel 20 ' is a scanning glass 50 ', and a brush 70 is disposed above the scanning channel 20 '. When the scanner scans the paper, dust is accumulated on the scanning glass 50 ' of the scanning passage 20 ', and the dust is attracted by the electrostatic force on the scanning glass 50 '. When the paper passes through the scanning channel 20 ', the paper advances along the scanning glass 50 ' toward the paper discharging channel 30 ', and since the scanning channel 20 ' is a horizontal channel, the paper moves along the horizontal path when passing through the scanning channel 20 ', and thus is harder to tightly contact with the scanning glass 50 ', so that the paper can only carry a part of the dust out of the scanning channel 20 ', and the remaining dust remains on the scanning glass 50 ' due to the influence of the electrostatic force, and at this time, in the neutral position of the paper, the brush 70 above the scanning channel 20 ' needs to rotate to clean the dust on the scanning glass 50 ' out of the scanning channel 20 '.

However, this method of cleaning the dust increases the volume of the internal components of the scanner 200 ', and requires a motor to rotate the brush 70, which additionally increases the power consumption of the scanner 200', the overall design volume, and the noise generation.

Therefore, there is a need for a scanning module that can save the required parts inside, save space, reduce noise, and keep the effect of cleaning dust.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can be when the paper scans to the defect that prior art exists with not enough, maintain the scanning module of scanning quality.

In order to achieve the above object, the present invention discloses a scanning module, which is disposed in a scanner and includes a paper feeding passage, a fixing bracket and a scanning glass. A scanning channel connected with the paper feed channel is arranged behind the paper feed channel; the fixed support is arranged above the scanning channel and matched with the scanning channel, an accommodating space is arranged in the fixed support, an opening of the accommodating space is formed in an oblique direction, the oblique direction is formed towards the paper feeding channel, and the scanning channel forms an oblique channel; the scanning glass is arranged at the opening of the accommodating space and covers the accommodating space, and the scanning glass and the scanning channel are in an inclined state.

As a further improvement, a plurality of light source emitters and a plurality of photoelectric sensors are arranged in the accommodating space.

As described above, by setting the scanning glass and the scanning channel to be in an oblique state, when the paper passes through the scanning channel, the paper can be forced to be in close contact with the scanning glass by the oblique state design, so that the paper can simultaneously carry away dust on the scanning glass, and thus, redundant cleaning components can be omitted, and the dust can be prevented from being accumulated in the scanning channel, so as to maintain the scanning quality of the scanning module on the paper.

Detailed Description

For the purpose of illustrating the technical content, the constructional features, the achieved objects and the effects of the invention in detail, reference is made to the following detailed description of the embodiments taken in conjunction with the accompanying drawings.

Referring to fig. 1 and 2, the present invention discloses a scanning module 100, wherein the scanning module 100 is disposed in a scanner 200. The utility model discloses scanning module 100 is used for scanning paper 300, and inside is equipped with one and the paper feed passageway 10 of outside UNICOM, and the direction of definition paper 300 feed-in is the place ahead, and the opposite direction with the paper 300 feed-in is the rear, the rear of paper feed passageway 10 is equipped with the scanning passageway 20 that the paper supply that is connected with paper feed passageway 10 passes through, and the rear of scanning passageway 20 is equipped with one and scans the play paper passageway 30 that passageway 20 is connected. The scanning module 100 is provided with a scanning glass 50.

The scanning module 100 includes a fixing bracket 40 extending transversely, the fixing bracket 40 has an accommodating space 41 therein, an opening of the accommodating space 41 is opened in an oblique direction, and the oblique direction is toward the paper feeding path 10. The scanning glass 50 is disposed at the opening of the accommodating space 41 and covers the accommodating space 41. The accommodating space 41 is provided with a plurality of light emitters 60 and a plurality of photo sensors (not shown). The light emitters 60 and photosensors are arranged normal to the scanning glass 50 so that the depth of field of the scanner can be maintained. Since the opening of the accommodating space 41 is disposed to be deviated from the paper feeding path 10, the scanning glass 50 is in an inclined state, so that the plurality of light source emitters 60 and the plurality of photosensors are not disposed to be horizontal to the bottom surface. The light emitters 60 are respectively configured to emit a light through the scanning glass 50 onto the paper 300 passing through the scanning passage 20, and the paper 300 reflects the light through the scanning glass 50 and into the photosensors. The scanning operation for the paper 300 is thus performed.

Referring to fig. 3 and 4, when the scanning module 100 of the present invention is used, dust 400 is generated in the scanning channel 20, and the dust 400 is adsorbed on the scanning glass 50 by electrostatic force generated by friction between the scanning glass 50 and paper. Since the scanning glass 50 is in an oblique state, the scanning channel 20 between the scanning glass 50 and the bottom surface is an oblique channel which is inclined downwards. Therefore, when the paper 300 enters the scanning path 20 from the paper feeding path 10, since the scanning path 20 is a downward inclined path, the front end of the paper 300 contacts the scanning glass 50 as the top wall of the scanning path 20 first, and the moving path of the paper 300 is limited by the downward inclined surface of the scanning glass 50, so that the paper 300 can closely adhere to the scanning glass 50 and move forward to the paper discharging path 30, and at this time, the dust 400 is between the scanning glass 50 and the paper 300, and the dust 400 is carried away from the scanning glass 50 along with the movement of the paper 300 due to the friction force generated by the paper 300 and the glass. Thus, the dust 400 in the scanning channel 20 can be removed to maintain the scanning quality of the paper 300 by the scanning module 100.

As mentioned above, by setting the scanning glass 50 and the scanning channel 20 in an oblique state, when the paper 300 passes through the scanning channel 20, the paper 300 can be brought into close contact with the scanning glass 50, so that the paper 300 can be simultaneously taken away from the dust 400 on the scanning glass 50, thereby omitting an extra cleaning component, preventing the dust 400 from being accumulated in the scanning channel 20, and thus maintaining the scanning quality of the paper 300 by the scanning module 100.
