Description

Mouse having scanning function {Mouse having scanning funtion}

The present invention relates to a mouse equipped with a scanning function.

In general, a mouse is a type of computer input device and performs functions such as selecting a program through a click operation, loading, operating, stopping, and opening / closing a screen. Recently, a convergence mouse that combines a scanning function in addition to a conventional mouse function has emerged as a convergence concept.

A mouse equipped with a scanning function is also called a handheld scanner because it performs a scan operation by moving a hand. At present, as disclosed in Korean Patent Laid-Open Publication No. 10-2006-0044271, a mouse having a scanning function having a function of recognizing an image such as a bar code has been released.

However, the conventional scanner mouse such as the above-described patent has the following problems due to its structural characteristics.

First, since the camera is a structure that photographs the scan area in a straight line from above, the height of the camera must be secured in order to focus clearly. As a result, the height of the mouse is increased, and the overall size of the mouse is increased.

Second, since the light source is located next to the camera, the ghost phenomenon that light emitted from the light source hits the scan area and then is reflected and projected to the camera causes blurry photo shadows to occur in the camera lens portion.

Third, the light source is located directly above the scan window, so that the light emitted from the light source does not diffuse sideways and the light is concentrated in the center of the light source, resulting in a hot spot phenomenon. That is, the light emitted from the light source does not spread evenly to the area, the brightness of the edge of the scan window is darker than the central area, the brightness unevenness occurs, and furthermore, the scanning performance is deteriorated due to the difference in brightness of the scanning target surface.

The present invention has been proposed to improve the above problems.

Mouse equipped with a scanning function according to an embodiment of the present invention for achieving the above object, in the mouse with a scanning function, the base including a scan window, and a cover member coupled to the upper surface of the base A case; A scan button provided on one surface of the case; And a scanner housed in the case and seated in the scan window, wherein the scanner comprises: a housing defining an optical path therein; A glass mounted on a bottom surface of the housing and fitted into the scan window; A glass frame supporting the glass; A mirror mounted obliquely on an upper side of the housing; A camera mounted on a side of the housing that is opposite to the mirror and having an image reflected from the mirror; And a light source assembly installed obliquely on an upper side of the housing spaced apart from the camera, and a reflective layer is formed on at least a portion of the inner circumferential surface of the glass frame.

According to the mouse with a scanning function according to an embodiment of the present invention constituting the above configuration has the following advantages and effects.

First, there is an advantage that a light source is installed at a position spaced apart from the photographing area of the camera, thereby preventing a phenomenon that the light source is scanned together.

Second, since the light source is installed at a sufficient distance from the scan window, and the reflective layer for light diffusion is coated on the inner side area of the scan window, the light is uniformly irradiated to the scan area, thereby maintaining the brightness uniformly.

Third, since the camera is installed in the inner side region of the mouse, the overall volume of the mouse is reduced, so that the grip sensitivity of the user is improved.

Fourth, since the reflective layer for the optical acid is formed, not only diffuses the light emitted from the light source but also increases the utilization of light, there is an advantage that can be effective light intensity with a small number of light sources.

In addition, since the light is evenly spread by the reflective layer, there is an effect of blocking the ghost phenomenon generated by the light reflected toward the camera while the light is concentrated in a specific area.

Fifth, the diffusion lens for light diffusion is provided on the front of the light source, the light diffusion area is wider, evenly irradiated to the scan area, there is an advantage that can be effective light intensity with a small number of light sources.

Sixth, by installing a supporter on the rear surface of the mirror which reflects the image of the scanning area and sends it to the camera lens and makes the mirror adhere to the front surface of the supporter, it does not press a specific part of the mirror, so that the scan screen due to the bending of the mirror There is an advantage that the distortion does not occur. In addition, since the bending of the mirror is prevented, there is an advantage of preventing the ghost caused by the diffuse reflection of light inside the scanner.

1 is an external perspective view of a mouse provided with a scanning function according to an embodiment of the present invention, Figure 2 is an exploded perspective view of the mouse.

1 and 2, a mouse 10 according to an embodiment of the present invention includes a case forming an appearance and a plurality of parts mounted inside the case.

In detail, the case includes a base 16 on which a viewing window 161 is formed, and a cover coupled to an upper surface of the base 16, wherein the cover includes an upper cover 11, a middle cover 12, and A lower cover 13.

In addition, the mouse 10 includes a main substrate 15 attached to the upper surface of the base 16, a scanner 20 seated on the viewing window 161, and a front upper surface of the main substrate 15. It further includes a scroller 14 to be placed, a scan button 17 mounted on the side of the case for inputting a scan command, and a mouse sensor 18 mounted on the front end and the bottom of the base 16, respectively. . The mouse sensor 18 may be mounted to face the upper end of the base 16 at a lower end or face to the diagonal.

In detail, the main substrate 15 is provided to cover the bottom region of the base 16 except for the viewing window 161. In addition, the scanner 20 is seated on the viewing window 161. In addition, the plurality of mouse sensors 18 are provided to accurately recognize the scan target even when the movement of the mouse 10 is irregular. When only one mouse sensor 18 is mounted, there is a problem in that the mouse 10 does not detect the movement when the mouse 10 is curved or moved in a left or right direction but obliquely up and down without moving in a left and right direction. However, when at least two mouse sensors 18 are mounted at positions facing each other, two-dimensional coordinates may be accurately recognized to accurately recognize a movement trajectory of the mouse. That is, even if the mouse does not move in the horizontal direction (two-dimensional X-axis movement) on the scan object but moves obliquely or moves in a curve, the photographed scan screen does not overlap or be distorted and can be scanned accurately.

Hereinafter, a scanner mounted on the mouse 10 will be described in detail with reference to the accompanying drawings.

3 is a perspective view of a scanner according to an embodiment of the present invention, Figure 4 is an exploded perspective view of the scanner.

3 and 4, the scanner 20 according to the embodiment of the present invention includes a housing 21, a glass frame 22 mounted on the bottom of the housing 21, A mirror 24 mounted obliquely on one side of the upper surface of the housing 21, a light source assembly obliquely mounted on the other side of the upper surface of the housing 21 and one side of the housing 21 opposite to the mirror 24; Camera 27 to be mounted.

In detail, a hole for mounting the glass 23 is formed in the bottom of the glass frame 22, and a reflecting layer 221 is coated on the inner circumferential surface of the glass frame 22. The glass 23 may be mounted on the bottom of the glass frame 22, or may be mounted on the viewing window 161 of the base 16. However, dust or foreign matter may enter the scanner 20. In order to prevent the inflow is preferably mounted on the bottom of the glass frame 22.

The reflective layer 221 is provided to evenly spread the light irradiated from the light source assembly on the entire surface of the glass 23, and is coated through a silk printing or optical printing method. As the reflective layer 221 is formed, light does not reach the edge region of the glass 23, that is, the edge region of the scan region, or the light does not reach the opposite side of the side from which the light is irradiated from the light source. Can not prevent the phenomenon. To this end, the light source assembly is mounted at a distance such that light is diffused from the light source assembly and the irradiation area irradiated onto the glass 23 is larger than the area of the glass 23. In addition, the light that escapes the glass 23 impinges on the reflective layer 221 and is then reflected back into the glass 23. Then, the light that is irradiated and hit from the light source assembly is reflected by the reflective layer 221 is irradiated to the opposite side. Therefore, since the light is sufficiently transmitted to the region opposite to the region where the light is irradiated from the light source, there is an advantage that the luminance is uniform throughout the scan region.

On the other hand, the mirror 24 is mounted on the stepped portion 212 which is surrounded by the edge of the mirror hole 211, is assembled in the form covered by the supporter 241. The stepped portion 212 is formed so that the front edge of the mirror 24 is in close contact with a predetermined width, so that a force is not applied to a specific portion of the mirror 24. The entire back surface of the mirror 24 is pressed by the supporter 241 with uniform force, and as a result, the four edges of the mirror are pressed with uniform force. Therefore, the mirror is not bent and the scan screen is not distorted.

In addition, the light irradiated from the light source assembly is reflected a plurality of times in the internal space of the scanner 20, that is, the optical path. In this process, when light emitted from the light source assembly is projected onto the camera 27, a ghost phenomenon may occur due to diffuse reflection of light. In order to block such a phenomenon, the inner circumferential surface of the housing 21, that is, the surface exposed to light is textured, and the glass 23 and the mirror 24 are subjected to an anti reflection coating (ARC) process. Minimize secondary reflections.

The light source assembly may include a light source 25, a substrate 251 on which the light source 25 is mounted, a diffusion lens 26 covering the front surface of the light source 25, and the light source 25. Wrapping includes a light source cover 252.

In detail, the light source 25 may include LED elements, and may be mounted on the left and right sides one by one. In addition, the diffusion lens 26 is mounted to increase the diffusion angle of the light emitted from the light source 25, which will be described in detail with reference to the accompanying drawings. In addition, the light source cover 252 has a shape in which the longitudinal section is recessed to form a substantially triangular shape. This is to prevent the light source 25 from being photographed by the camera 27 by mounting the light source 25 at a position spaced apart from each other. The substrate 251 is mounted at an angle to the glass 23 so that the light reaches the glass 23 sufficiently. Since the light source 25 is mounted obliquely at a point spaced laterally from the right side of the glass 23, the light travel distance is longer than the case where the light source 25 is located directly above the glass 23. Volume has the advantage of minimizing.

In addition, the camera 27 is mounted on the side of the housing 21 corresponding to the opposite side of the mirror 24 in the state of being mounted on the front of the back cover 271. Accordingly, the scan object under the glass 23 is reflected by the mirror 24 to form an image on the camera 27.

Hereinafter, a process in which the movement of light and the image of the scan target formed inside the scanner 20, that is, on the optical path, are formed on the camera will be described in detail with reference to the accompanying drawings.

5 is a cross-sectional view taken along the line II of FIG. 3.

Referring to FIG. 5, light emitted from the light source 25 diffuses while passing through the diffusion lens 26 and is mostly irradiated toward the glass 23. The area of light irradiated from the light source 25 to the upper surface of the glass 23 by the diffusion lens 26 is larger than the area of the glass 23. That is, part of the light diffused by the diffusion lens 26 is also irradiated to the reflective layer 221. In addition, the light irradiated onto the reflective layer 221 is reflected to the edge region of the glass 23, so that the luminance is uniformly maintained without a dark region inside the glass 23.

In addition, since the inner circumferential surface of the housing 21 is textured, and an anti-reflection film is formed on the glass 23 and the mirror 24, the light hitting the inner circumferential surface of the housing 21 or the glass 23 or the Light directly irradiated onto the mirror 24 is reflected back to prevent the phenomenon of forming on the camera 27. Therefore, the ghost phenomenon that the light blurring does not occur.

On the other hand, according to the structure of the scanner 20 according to the embodiment of the present invention, because the scan object is reflected only once through the mirror 24 and formed on the camera 27, there is an advantage of minimizing image distortion. And, as described above, since the camera 27 is mounted on the side of the scanner 20, it is possible to minimize the volume increase of the mouse (10).

6 is a front perspective view of a diffuser lens mounted to a light source of a scanner according to an exemplary embodiment of the present invention, and FIG. 7 is a bottom perspective view of the diffuser lens.

6 and 7, the diffusion lens 26 includes a lens part 261 that is convexly rounded so as to diffuse light emitted from the light source 25, and a fastening extending from an edge of the lens part. Part 262 is included. The light source accommodating part 263 in which the light source 25 is accommodated is recessed in the center of the bottom of the lens part 261.

In detail, the lens unit 261 may be provided in a shape in which two spherical lenses overlap. The light source accommodating part 263 may be formed in a hemispherical shape in an area where two spherical lenses overlap. In addition, the diffusion lens 26 may be manufactured as a free-form lens, which has recently been in the spotlight.

As illustrated, when the diffusion lens 26 is mounted on the front surface of the light source 25, the light emitted from the light source 25 is primarily refracted while passing through the light source accommodating part 263. Secondary refraction is performed while passing through the lens portion 261. The refraction direction is refracted in the direction in which light spreads. Therefore, compared with the case where there is no diffusion member in the front surface of the light source 25, the diffusion angle is increased, there is an advantage that the light is irradiated to a large area.
