[0028] Referring to Figures 2 to 4, the main body 110 of the multi-functional document processing device 100 according to this embodiment has a structure that incorporates a document scanning unit 111, which has a fixing surface 111a formed on its upper surface that can securely attach a document to be scanned. In addition, a document ejection port 112a is formed on one side from a printing output unit 112 installed inside, and a screen output unit 120 is attached to the upper surface on one side of the upper part by a hinge structure 113 so that it can be folded.

[0029] Depending on the circumstances, a manual input unit 114 may be further mounted on the upper surface of the main body 110 adjacent to the mounting surface.

By wirelessly connecting to the user's smart device via the wireless communication module 115, the system can receive document information provided by the user's smart device and then perform document editing tasks required by the user based on the received data. More preferably, an application that can control the operation of the multifunctional document processing device 100 can be installed on the user's smart device, allowing the operation of the multifunctional document processing device 100 to be controlled remotely.

[0031] On the other hand, the screen output unit 120 in this embodiment is mounted on one side of the upper part of the main body 110 by a hinge structure 113. In this case, the screen output unit 120 is a structure to which Mopic Light Field 3D technology is applied, which can output a three-dimensional image or video in response to a control signal transmitted from the screen output control unit 150. It is an electrostatic touchscreen structure that senses the user's touch on the screen and transmits the touch coordinate values ​​to the screen output control unit 150.

[0032] In this embodiment, the screen output control unit 150 is configured to be mounted inside the main unit 110 and can control the operation of the screen output unit 120 based on data acquired from the screen output unit 120, the first motion sensing unit 131, and the translation processing unit 152.

[0033] Specifically, the screen output control unit 150 can output a three-dimensional image or video to the screen output unit 120 so that the screen, separated into multiple work windows, can be arranged by the user's finger touch. The screen output control unit 150 can output character information acquired from the document scanning unit 111, translated character information, or a dictionary corresponding to the language selected by the user to the aforementioned three-dimensional image or video. In addition, the screen output control unit 150 can output a keyboard image to the three-dimensional image that can receive control values ​​required by the user.

[0034] In this embodiment, the translation processing unit 152 is configured to be mounted inside the main unit 110, and can recognize character information based on document information acquired via the document scanning unit 111, translate the character information into a language selected by the user, and then transmit the processed information to the screen output control unit 150.

[0035] On the other hand, the first motion sensing unit 131 according to this embodiment, as mentioned above, is configured to be mounted in a structure that continuously surrounds the frame 121 of the screen output unit 120, as shown in Figures 2 and 3. It is formed to protrude from the surface of the screen output unit 120 by a predetermined height, and is structured to recognize when a finger approaches the surface of the screen output unit 120 by a predetermined distance and to detect the input coordinate value.

[0036] Specifically, as shown in Figure 3, the first motion sensing unit 131 has a structure that forms a width equal to a predetermined distance D from the surface of the screen output unit 120. At this time, it can recognize a finger approaching the surface of the screen output unit 120 and detect the coordinates of the finger. Furthermore, the three-dimensional image or video formed by the screen output unit 120 is formed at a predetermined height Dd from the surface of the screen output unit 120, as shown in Figure 3, and the user can be guided to touch a position that is a predetermined height away from the surface of the screen output unit 120.

[0037] In this embodiment, the RealSense camera unit 140 is mounted on the upper part of the frame of the screen output unit 120 and has a structure that detects the position and direction information of the user's fingers and pupils and transmits it to the screen output control unit 150.

[0038] Specifically, as shown in Figure 2, the RealSense camera unit 140 may be configured to include a second motion sensing unit 132 and a third motion sensing unit 133 that perform specific roles. The second motion sensing unit 132 of the RealSense camera unit 140 is configured to be mounted on the upper part of the frame of the screen output unit 120, and can capture the position of the user's arm and hand in real time to detect the position information of the arm and hand. The third motion sensing unit 133 of the RealSense camera unit 140 is also configured to be mounted on the upper part of the frame of the screen output unit 120, and can capture the user's pupil in real time to detect the direction information of the pupil.

[0039] In this embodiment, the coordinate correction unit 151 is configured to be mounted inside the kiosk main body 110, and can correct the first coordinate result value based on the data acquired via the second motion sensing unit 141 and the third motion sensing unit 142, calculate the second coordinate result value, and transmit it to the screen output control unit 150.

[0040] At this time, the screen output control unit 150 according to this embodiment calculates a first coordinate result value based on the touch sensing coordinate value obtained from the screen output unit 120 and the input coordinate value obtained from the first motion sensing unit 130, and then controls the screen output unit 120 to output a corresponding 3D image or video based on the first coordinate result value, and can control the operation of the screen output unit 120 based on the data obtained from the coordinate correction unit 151.

[0041] Depending on the circumstances, a wireless communication module (not shown) may be built into the screen output unit 120 and the coordinate correction unit 151, allowing them to be controlled wirelessly in conjunction with the operator's portable smart device S. Specifically, the content output to the screen output unit 120 can be mirrored and output to the operator's portable smart device S, and the content output from the screen output unit 120 can be changed according to the operator's intentions by changing the correction setting value of the coordinate correction unit 151. In addition, data stored on the operator's portable smart device S can be used to output to the screen output unit 120.

[0042] In this case, according to this embodiment, by providing a first motion sensing unit 131, a second motion sensing unit 132, a third motion sensing unit 133, and a real sense camera unit 140 with a specific structure, errors in the data acquired via the first motion sensing unit 131 can be removed in real time, and as a result, the control command value that the user intends to select can be accurately detected, and the operation of the document scanning unit 111, the printing unit output unit 112, and the translation processing unit 152 can be easily operated based on the control command value, thereby providing a multi-functional document processing device.

[0043] Figure 5 shows a block diagram illustrating a multifunctional document processing apparatus according to another embodiment of the present invention, and Figure 6 shows a perspective view illustrating a multifunctional document processing apparatus according to another embodiment of the present invention. Figure 7 shows a longitudinal cross-sectional view illustrating the hologram output section of the multifunctional document processing apparatus according to another embodiment of the present invention, and Figures 8 to 11 show conceptual diagrams illustrating the principle by which the hologram optical section used in the hologram output section shown in Figure 7 forms multiple screen images. Figure 12 also shows a longitudinal cross-sectional view illustrating the hologram output section of the multifunctional document processing apparatus according to another embodiment of the present invention.

[0044] Referring to these drawings, the kiosk device 100 according to this embodiment may further include a hologram output unit 160 that can output a hologram image onto the upper and side space of the frame of the screen output unit 120.

[0045] In this embodiment, the hologram output unit 160 is mounted on the upper and side surfaces of the frame of the screen output unit 120, and can output command word information selected by the user, operating status information of the document scanning unit 111, and operating status information of the printing unit output unit 112 as a hologram stereoscopic image, separated by a predetermined distance from the frame of the screen output unit 120.

[0046] Specifically, as shown in Figure 6, the hologram output unit 160 according to this embodiment may be configured to include an upper output unit 160a, a left-side output unit 160b, and a right-side output unit 160c, each playing a specific role. The upper output unit 160a is mounted on the upper surface of the frame 121 of the screen output unit 120 and outputs a hologram stereoscopic image in front of the user's face. The hologram stereoscopic image may include emoticons and characters corresponding to command word information selected by the user. The left-side output unit 160b is mounted on the left side of the frame of the screen output unit 120 and outputs a hologram stereoscopic image to the left front of the user. The hologram stereoscopic image may include emoticons and characters corresponding to the operating status information of the document scanning unit 111. The right-side output unit 160c is mounted on the right side of the frame of the screen output unit 120 and outputs a hologram stereoscopic image to the right front of the user. The hologram stereoscopic image may include emoticons and characters corresponding to the operating status information of the printing unit output unit 112.

[0047] The hologram output unit 160 in this embodiment may include a lighting unit 161 of a specific structure, a hologram optical unit 163, a display panel 164, and an optical path conversion unit 162.

[0048] The illumination unit 161 of the hologram output unit 160 has a structure consisting of multiple light source units that are sequentially driven on / off. At this time, the hologram optical unit 163 has a structure in which, when light from the illumination unit 161 is incident, light is reproduced that forms multiple screen images in space that are spaced apart in the depth direction.

[0049] In this embodiment, the display panel 164 of the hologram output unit 160 modulates the light reproduced by the hologram optical unit 163 with a video signal, dividing one frame of video into multiple subframes equal to the number of light source units, and sequentially modulating multiple subframe videos that are imaged at positions separated in the depth direction.

[0050] At this time, the optical path conversion unit 162, which is positioned in the optical path between the illumination unit 161 and the hologram optical unit 163, changes the path so that the light illuminated by multiple light source units enters the hologram optical unit 163 at different angles of incidence, and has a structure that includes a Fresnel lens.

[0051] Specifically, the hologram output unit 160 in this embodiment can light up in a specific color and display a two-dimensional or three-dimensional screen image, and by utilizing the displayed screen image, it can effectively display menu images and alarm functions to kiosk users.

[0052] Specifically, the hologram output unit 160 in this embodiment sequentially reproduces light from a hologram element to form multiple screen images in a space separated by a predetermined height from the upper surface of the kiosk body unit 110. Then, it divides one frame of video into multiple subframes and modulates the sequentially reproduced light with the corresponding video signals to display a three-dimensional image that can be recognized by the naked eye of an elevator passenger or someone waiting to board.

[0053] The hologram optical unit 163 in this embodiment includes an illumination unit 161, the hologram optical unit 163, and a display panel 164. An optical path conversion unit 162 may be further provided between the illumination unit 161 and the hologram optical unit 163. A control unit C is also provided to control the driving of the illumination unit 161 and the display panel 164.

[0054] The lighting unit 161 includes a plurality of light source units, for example, a first light source unit 161a and a second light source unit 161b.

[0055] The number of light source units constituting the illumination unit 161 is the same as the number of screen images formed by the hologram optical unit 163. Light-emitting diodes, laser diodes, or general projector lamps can be used as light sources for the first light source 161a and the second light source unit 161b. The first light source unit 161a and the second light source unit 161b are turned on / off by the control unit C and are turned on / off alternately in synchronization with the time-division drive of the display panel 164, as will be described later.

[0056] The hologram optical unit 163 is provided to form multiple screen images that are spaced apart in space. For this purpose, the hologram optical unit 163 includes multiple hologram elements, each of which a plurality of screen images are recorded, so that it can reproduce the light that forms the plurality of screen images, and includes, for example, a first hologram element 163a and a second hologram element 163b.

[0057] The principle by which the first hologram element 163a and the second hologram element 163b form multiple screen images spaced apart in space is explained as follows.

[0058] Figures 8 and 9 show the process of fabricating the first hologram element 163a by recording a hologram corresponding to the screen image on the hologram medium 163a', and then reproducing the screen image from it. The hologram corresponding to the screen image can be formed, for example, by recording the image of the diffuser 10 on the hologram medium 163a'. The hologram medium 163a' is formed from a photosensitive medium such as a photoresist or photopolymer, and can store image information by optical interference fringes between object light containing image data and reference light that does not contain data. That is, when light is shone on the diffuser 10, object light Lo containing the image data of the diffuser 10 is emitted from the diffuser 10, and interference fringes formed by the interference of this object light Lo and reference light Lr1 that does not contain any image data are recorded on the hologram medium 163a'. At this time, a laser beam with good coherence is used as the light that forms the reference light Lr1. Figure 9 shows that the first hologram element 163a has recorded an image hologram of the diffuser 10, which is located at a distance d1 from the hologram medium 163a'. When the same reference light Lr1 used for recording is shone on the first hologram element 163a, the reference light Lr1 undergoes diffraction due to the hologram formed on the first hologram element 163a, thereby restoring the object light Lo. The restored object light Lo shows the diffuser image, which is equivalent to the formation of a screen S1 in space at a distance d1 from the first hologram element 163a.

[0059] Figures 10 and 11 show the process of fabricating a second hologram element 163b by recording a hologram corresponding to the screen image on the hologram medium 163b', and then reproducing the screen image. In this case, the diffuser 10 is moved a distance d2 away from the hologram medium 163b', and then object light Lo, which includes the image of the diffuser 10, and reference light Lr2, which does not include the image data, are irradiated onto the hologram medium 163b'. At this time, the angle at which the reference light Lr2 is incident on the hologram medium 163b' is different from the reference light Lr1 in Figures 8 and 9. Interference fringes formed by the interference of object light Lo and reference light Lr2 are recorded on the hologram medium 163b'. Figure 11 shows that the second hologram element 163b thus has the image hologram of the diffuser located at a distance d2 recorded on the hologram medium 163b'. When the reference light Lr2 used for recording on the second hologram element 163b is irradiated, the object light Lo is restored, and a screen S2 is formed at a distance d2 away from the second hologram element 163b.

[0060] The hologram output unit 160 of this embodiment employs a first hologram element 163a and a second hologram element 163b manufactured using this principle, and utilizes the characteristic that, in principle, a hologram is reproduced only at the angle of the reference light used for recording. That is, a hologram shows maximum efficiency when reproduced at the same angle as the reference light used for recording, and this angle is called the Bragg angle, but beyond this angle, the diffraction efficiency decreases sharply. When reproducing the holograms recorded on each of the first hologram elements 163a and the second hologram element 163b, if the angle of the illumination light is adjusted to match the respective Bragg angles, even if the first hologram element 163a and the second hologram element 163b overlap, the images recorded on each can be reproduced without interference between them.

[0061] The first light source unit 161a and the second light source unit 161b sequentially illuminate the first hologram element 163a and the second hologram element 163b with light at angles corresponding to the reference light for each of them. As a result, light is sequentially regenerated from the first hologram element 163a and the second hologram element 163b, which are imaged at different positions from each other.

[0062] As the holographic medium for forming the first holographic element 163a and the second holographic element 163b that constitute the holographic optical unit 163 described above, a holographic polymer dispersed liquid crystal (HPDLC) can be used. A polymer dispersed liquid crystal (PDLC) is a material formed by dispersing a polymer in a liquid crystal cell and has the property of being controlled between a transparent state and a diffused state by electrical control. In particular, it is known that when recording a hologram on HPDLC formed by dispersing a photopolymer in a liquid crystal cell, the holographic image can be electrically switched.

[0063] The display panel 164 modulates the light reproduced in the hologram optical unit 163 according to the video signal to form an image, and can be composed of, for example, a liquid crystal panel. Since the first hologram element 163a and the second hologram element 163b are located behind the display panel 164, the display panel 164 modulates the light reproduced by the first hologram element 163a and the second hologram element 163b according to the video signal. The display panel 164 divides one frame of video into multiple images and displays them alternately in a time-multiplexing manner. For example, one frame of video is divided into two subframe images, and the display panel 164 modulates the light according to the corresponding video signal for each. The two subframe images may consist of a background image I1 and a foreground image I2. The period in which the display panel 164 alternately displays the background image I1 and the foreground image I2 is shorter than the blink of the user's eye and is perceived as one frame of video, for example, shorter than 1 / 120 of a second. As shown in the diagram, the background image I1 creates a sense of depth for the user corresponding to the difference d between d2 and d1 in relation to the foreground image I2, thereby allowing the user to perceive a three-dimensional image.

[0064] The optical path conversion unit 162 is positioned in the optical path between the illumination unit 161 and the hologram optical unit 163, so that the light from the first light source unit 161a and the second light source unit 161b enters the hologram optical unit 163 at different angles. For example, the optical path conversion unit 162 converts the optical path so that the light from the first light source unit 161a and the second light source unit 161b has the same angle as the reference light used during hologram recording to the first hologram element 163a and the second hologram element 163b. To this end, the optical path conversion unit 162 may consist of a Fresnel lens positioned at an angle with respect to the fixed plate 161c on which the first light source unit 161a and the second light source unit 161b are mounted. The Fresnel lens plays a role in focusing and collimating light, and as shown in the figure, it is positioned at an angle to the fixed plate 161c, so that the light from the first light source unit 161a and the second light source unit 161b enters the Fresnel lens at different angles of incidence. Therefore, the light from the first light source unit 161a and the second light source unit 161b has paths that enter the hologram optical unit 163 at different angles to each other after passing through the Fresnel lens 121. The degree to which the Fresnel lens is tilted with respect to the fixed plate 161c can be appropriately determined by considering the reference light angle during hologram recording to the first hologram element 163a and the second hologram element 163b. In the drawing, one Fresnel lens is used as an example in the optical path conversion unit 162, but multiple path conversion members can be used, each positioned on the optical path from the first light source unit 161a and the second light source unit 161b, and other components such as multiple focusing lenses may also be provided. Furthermore, by mounting rotational drive units 161d and 162a on the fixed ends of the fixed plate 161c and the optical path conversion unit 162, the tilt of each can be adjusted to an optimal state. (See Figure 12)

[0065] The control unit C controls the operation of the illumination unit 161 and the display panel 164. For example, it controls the on / off switching of the first light source unit 161a and the second light source unit 161b in synchronization with the sequential modulation of video signals corresponding to two subframe images on the display panel 164. Furthermore, as described above, if the first hologram element 163a and the second hologram element 163b are made of holographic polymer dispersed liquid crystal, the control unit C controls the switching of each of the first hologram element 163a and the second hologram element 163b in synchronization with the illumination signal and the video signal.

[0066] As described above, the hologram optical unit 163 forms multiple screen images, and through the synchronized driving of the display panel 164 and the illumination unit 161, the user sees two images I1 and I2 with a difference of depth d, thereby perceiving a three-dimensional image. Furthermore, it is also possible to realize a typical two-dimensional image by using only one of the multiple light source units 161a and 161b that make up the illumination unit 161 and modulating the light with a two-dimensional video signal in the display panel 164.

[0067] In this case, according to this embodiment, by providing a hologram output unit 160 with a specific structure, it is possible to output holographic stereoscopic images including emoticons and characters independently to the front and left and right sides relative to the user's face, so that the command word information selected by the user, the operating status information of the document scanning unit 111, and the operating status information of the printing unit output unit 112 can be intuitively understood. As a result, a multi-functional document processing device can be provided that maximizes ease of use.

However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather includes all variations, equivalents, and substitutes that fall within the spirit and scope of the invention as defined by the appended claims.

[0069] In other words, the present invention is not limited to the specific embodiments and descriptions described above, and any person with ordinary skill in the art to which the present invention belongs can carry out various modifications without departing from the gist of the invention as claimed in the claims, and such modifications should be included within the scope of protection of the present invention.
