Background Art

[0002] Recently, with the development of office automation technology, the demand for office equipment has been increasing, and various devices having various functions, for example, a device called a multi-function copier having a structure as shown in FIG. 1, have been introduced in various ways.

[0003] The multi-function copier shown in FIG. 1 is a device that has all the functions of a facsimile, a copier, a printer, and a scanner, and includes a scanner, a print engine, and a host PC interface to execute various functions.

[0004] Generally, a scanner is an optical character reader that acquires characters recorded on a paper surface or the like as image information, reconverts the acquired image information into data corresponding to the characters by using a method such as optical character recognition (OCR), and then outputs the character information to a display device.

[0005] Recently, it has also been possible to receive color films, original color photos, pictures, etc. at high resolution and perform color separation, and it is positioned as an essential tool for video processing and electronic publishing.

Further, the screen output control unit 150 can output a keyboard image that can receive a control value required by the user from the user for the 3D image.

[0034] The translation processing unit 152 according to the present embodiment is configured to be mounted inside the main body unit 110. Based on the document information acquired through the document scanning unit 111, it recognizes character information, translates the character information into the language selected by the user, and then can transmit the processed information to the screen output control unit 150.

[0035] On the other hand, as shown in FIGS. 2 and 3, the first motion sensing unit 131 according to the present embodiment is configured to be mounted in a structure that continuously surrounds the frame 121 of the screen output unit 120. It protrudes from the surface of the screen output unit 120 by a predetermined height. When a finger approaches the surface of the screen output unit 120 by a predetermined distance, it recognizes this and detects the input coordinate value.

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

[0037] The real-sense camera unit 140 according to this embodiment is configured to be 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 finger and pupil and transmits it to the screen output control unit 150.

[0038] Specifically, as shown in FIG. 2, the real-sense camera unit 140 may include a second motion sensing unit 132 and a third motion sensing unit 133 that play specific roles. The second motion sensing unit 132 of the real-sense 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 positions of the user's arm and hand in real time and detect the position information of the arm and hand. Also, the third motion sensing unit 133 of the real-sense 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 user's pupil in real time and detect the direction information of the pupil.

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

[0040] At this time, the screen output control unit 150 according to this embodiment calculates the 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 three-dimensional 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] In some cases, a wireless communication module (not shown) is built into the screen output unit 120 and the coordinate correction unit 151, and can be controlled in wireless linkage 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 correction setting value of the coordinate correction unit 151 can be changed to change the content output from the screen output unit 120 according to the operator's intention. Also, the data stored in 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 the first motion sensing unit 131, the second motion sensing unit 132, the third motion sensing unit 133, and the real sense camera unit 140 of a specific structure, the error of the data acquired through 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 a multifunctional document processing apparatus can be provided that can easily operate the operations of the document scanning unit 111, the printing unit output unit 112, and the translation processing unit 152 according to the control command value.

[0043] FIG. 5 shows a block configuration diagram of a multifunctional document processing apparatus according to another embodiment of the present invention, and FIG. 6 shows a perspective view of a multifunctional document processing apparatus according to another embodiment of the present invention. Also, FIG. 7 shows a longitudinal sectional view of a hologram output unit of a multifunctional document processing apparatus according to another embodiment of the present invention, and FIGS. 8 to 11 show conceptual diagrams for explaining the principle by which the hologram optical unit employed in the hologram output unit shown in FIG. 7 forms a plurality of screen images. Also, FIG. 12 shows a longitudinal sectional view of a hologram output unit of a 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 be configured to further include a hologram output unit 160 that can output a hologram image on the upper and side spaces of the frame of the screen output unit 120.

[0045] The hologram output unit 160 according to this embodiment is configured to be mounted on the upper surface and the side surfaces of the frame of the screen output unit 120, and can output the command word information selected by the user, the operation state information of the document scanning unit 111, and the operation state information of the printing unit output unit 112 as a holographic three-dimensional image separated by a predetermined distance from the frame of the screen output unit 120.

[0046] Specifically, as shown in FIG. 6, the hologram output unit 160 according to this embodiment may include an upper output unit 160a, a left-side output unit 160b, and a right-side output unit 160c that play specific roles. The upper output unit 160a is mounted on the upper surface of the frame 121 of the screen output unit 120 and outputs a holographic three-dimensional image in front of the user's face. The holographic three-dimensional image may include emoticons and characters corresponding to the command word information selected by the user. The left-side output unit 160b is mounted on the left side surface of the frame of the screen output unit 120 and outputs a holographic three-dimensional image in front of the user's left side. The holographic three-dimensional image may include emoticons and characters corresponding to the operation state information of the document scanning unit 111. Further, the right-side output unit 160c is mounted on the right side surface of the frame of the screen output unit 120 and outputs a holographic three-dimensional image in front of the user's right side. The holographic three-dimensional image may include emoticons and characters corresponding to the operation state information of the printing unit output unit 112.

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

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

[0049] The display panel 164 of the hologram output unit 160 according to this embodiment modulates the light reproduced by the hologram optical unit 163 with a video signal, and a video of one frame is divided into a plurality of the same number as the number of light source units, and a plurality of sub-frame videos imaged at positions separated in the depth direction can be sequentially modulated.

[0050] At this time, the optical path conversion unit 162 disposed in the optical path between the illumination unit 161 and the hologram optical unit 163 changes the path so that the light illuminated by the plurality of light source units enters the hologram optical unit 163 at different incident angles, and has a structure including a Fresnel lens.

[0051] Specifically, the hologram output unit 160 according to this embodiment lights up in a specific color and can embody a two-dimensional screen video or a three-dimensional screen video, and uses the embodied screen video to effectively execute a menu video and an alarm function for a kiosk device user.

[0052] Specifically, the hologram output unit 160 according to this embodiment sequentially reproduces light for imaging a plurality of screen videos in a space separated by a predetermined height from the upper surface of the kiosk main body unit 110 from the hologram element, and then divides a video of one frame into a plurality of sub-frame videos, and modulates the light sequentially reproduced by corresponding video signals to display a three-dimensional video recognizable by the naked eyes of an elevator passenger or a person waiting to board.

[0053] The hologram optical unit 163 according to this embodiment includes an illumination unit 161, a hologram optical unit 163, and a display panel 164, and an optical path conversion unit 162 can be further provided between the illumination unit 161 and the hologram optical unit 163. Also, a control unit C for controlling the driving of the illumination unit 161 and the display panel 164 is provided.

[0054] The illumination 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 a plurality of screen images formed by the hologram optical unit 163. As the light sources of the first light source 161a and the second light source unit 161b, a light emitting diode or a laser diode can be adopted, or a general projector lamp can be adopted. The first light source unit 161a and the second light source unit 161b are driven on / off by the control unit C, and as will be described later, they are alternately turned on / off in synchronization with the time-division driving of the display panel 164.

[0056] The hologram optical unit 163 is provided to form a plurality of screen images that are spatially separated. For this purpose, the hologram optical unit 163 includes a plurality of hologram elements in which a plurality of screen images are respectively recorded so that the light forming the plurality of screen images can be reproduced. For example, it includes a first hologram element 163a and a second hologram element 163b.

[0057] Here, the principle by which the first hologram element 163a and the second hologram element 163b form a plurality of screen images that are spatially separated is as follows.

[0058] Figures 8 and 9 show the process of recording a hologram corresponding to a screen image on the hologram medium 163a’ to fabricate the first hologram element 163a, and then playing back the screen image. 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 of a material such as photoresist or photopolymer as a photosensitive medium sensitive to light, and can store video information by optical interference fringes of object light containing video data and reference light not containing data. That is, when light irradiates the diffuser 10, object light Lo containing diffuser 10 video data exits from the diffuser 10, and interference fringes formed by the interference of this object light Lo and reference light Lr1 not containing any video data are recorded on the hologram medium 163a’. At this time, a laser beam with good coherence is used as the light forming the reference light Lr1. Figure 9 shows that the first hologram element 163a has recorded the video hologram of the diffuser 10 located at a distance d1 from the hologram medium 163a’ in this way. When irradiated with the same reference light Lr1 used when recording on the first hologram element 163a, the reference light Lr1 is diffracted by the hologram formed on the first hologram element 163a, whereby the object light Lo is restored. The restored object light Lo shows the diffuser image, which is similar to the formation of the screen S1 in the space separated by the distance d1 from the first hologram element 163a.

[0059] Figures 10 and 11 show the process of recording a hologram corresponding to the screen video on the hologram medium 163b’ to fabricate the second hologram element 163b, and then playing back the screen video. This time, after separating the diffuser 10 from the hologram medium 163b’ by a distance d2, the object light Lo including the diffuser 10 video and the reference light Lr2 not including video data are irradiated onto the hologram medium 163b’. At this time, the angle at which the reference light Lr2 enters the hologram medium 163b’ is made different from that of the reference light Lr1 in FIGS. 8 and 9. The interference fringes formed by the interference of the object light Lo and the reference light Lr2 are recorded on the hologram medium 163b’. Figure 11 shows that the second hologram element 163b has recorded the video hologram of the diffuser located at a distance d2 on the hologram medium 163b’ in this way. When irradiated with the reference light Lr2 used when recording on the second hologram element 163b, the object light Lo is restored, and a screen S2 is formed at a location separated from the second hologram element 163b by a distance d2.

[0060] The hologram output unit 160 of this embodiment employs the first hologram element 163a and the second hologram element 163b fabricated based on such a principle, and in principle, utilizes the characteristic that the hologram is reproduced only by the angle of the reference light used for recording. That is, the hologram exhibits the maximum efficiency when reproduced at the same angle as the reference light during recording, and this angle is referred to as the Bragg angle. However, when exceeding this angle, the diffraction efficiency rapidly decreases. When reproducing the holograms recorded on the respective first hologram element 163a and 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 interfering with each other.

[0061] In the first light source unit 161a and the second light source unit 161b, light is sequentially illuminated so that light enters the first hologram element 163a and the second hologram element 163b at angles corresponding to the reference light of the first hologram element 163a and the second hologram element 163b, respectively. As a result, light imaged at different positions from each other from the first hologram element 163a and the second hologram element 163b is sequentially reproduced.

[0062] As the hologram medium forming the first hologram element 163a and the second hologram element 163b constituting the hologram optical unit 163 described above, holographic polymer dispersed liquid crystal (HPDLC) can be used. The 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 to a transparent state and a diffused state by electrical control. In particular, when a hologram is recorded on an HPDLC formed by dispersing a photopolymer in a liquid crystal cell, it is known that the hologram video can be electrically switched.

[0063] The display panel 164 modulates the light reproduced in this manner by 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 arranged 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 the video of one frame into a plurality of videos and alternately realizes them in a time multiplexing manner. For example, the video of one frame is divided into two sub-frame videos, and the display panel 164 modulates light according to the corresponding video signal. The two sub-frame videos can consist of a background video I1 and a front video I2. When the period in which the display panel 164 alternately realizes the background video I1 and the front video I2 is shorter than the blink of the user's eye, it is recognized as the video of one frame. For example, it is shorter than 1 / 120 second. The background video I1 forms a depth sense of only d corresponding to the difference between d2 and d1 for the user with respect to the front video I2 as shown in the drawing, and thereby, a three-dimensional image can be recognized.

[0064] The optical path conversion unit 162 is disposed on 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 respectively. 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 angles of the reference light used at the time of hologram recording with respect to the first hologram element 163a and the second hologram element 163b. For this purpose, the optical path conversion unit 162 may be composed of a Fresnel lens disposed so as to be inclined 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 serves to collect and collimate light, and as shown in the figure, since it is disposed so as to be inclined with respect to the fixed plate 161c, the light from the first light source unit 161a and the second light source unit 161b enters the Fresnel lens at different incident angles respectively. 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 after passing through the Fresnel lens 121. The degree to which the Fresnel lens is inclined with respect to the fixed plate 161c can be appropriately determined in consideration of the reference light angles at the time of hologram recording with respect to the first hologram element 163a and the second hologram element 163b. In the drawings, one Fresnel lens is illustrated and described as the optical path conversion unit 162, but a plurality of path conversion members respectively disposed on the optical paths from the first light source unit 161a and the second light source unit 161b can be adopted, and further, a plurality of condenser lenses and the like may be provided. Also, rotation drive units 161d and 162a are mounted on the fixed end of the fixed plate 161c and the optical path conversion unit 162, and the respective inclination degrees can be adjusted to an optimal state. (See FIG. 12)

[0065] The control unit C controls the driving of the lighting unit 161 and the display panel 164. For example, in synchronization with sequentially modulating video signals corresponding to two sub-frame videos on the display panel 164, the on / off states of the first light source unit 161a and the second light source unit 161b are controlled. Further, as described above, when the first hologram element 163a and the second hologram element 163b are made of holographic polymer dispersed liquid crystal, each of the first hologram element 163a and the second hologram element 163b is controlled to be switched in synchronization with the illumination signal and the video signal.

[0066] As described above, while the hologram optical unit 163 forms a plurality of screen videos, due to the synchronized driving of the display panel 164 and the lighting unit 161, the user comes to see two videos I1 and I2 with a depth difference of d, and thus perceives a three-dimensional video. Also, by using only one of the plurality of light source units 161a and 161b constituting the lighting unit 161 and modulating light with a two-dimensional video signal on the display panel 164, it is also possible to embody a general two-dimensional video.

[0067] In this case, according to this embodiment, by providing the hologram output unit 160 with a specific structure, it is possible to independently output a holographic three-dimensional video including emoticons and characters to the front and each of the left and right sides based on the user's face, so that the command word information selected by the user, the operation state information of the document scanning unit 111, and the operation state information of the printing unit output unit 112 can be intuitively understood. As a result, it is possible to provide a multifunctional document processing apparatus that can maximize the convenience in use.

[0068] In the above detailed description of the present invention, only specific embodiments thereof have been described. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, and includes all modifications, equivalents, and alternatives within the spirit and scope of the present invention defined by the appended claims.

[0069] That is, the present invention is not limited to the specific embodiments and descriptions described above, and any person having ordinary knowledge in the technical field to which the present invention pertains can implement various modifications without departing from the gist of the present invention claimed in the claims, and such modifications should be included within the protection scope of the present invention.
