As the side area, there is an area corresponding to the machine operation input and an area corresponding to the input. The wood processing unit 42 obtains a movie image obtained by the photographing unit 41 at 9/30 201205354 every designated time. The processing unit 42 obtains a difference between the captured image and the captured image in the initial state (the state in which the input is not operated) in each of the detection regions, and obtains the detection region. The total of the difference 値 within each. The processing unit 42 compares the total of the difference 値 with the threshold 値. When the total sum of the difference values is larger than the threshold ,, the processing unit 42 determines that there is a handle corresponding to the Detective area. When the total of the difference values is equal to or less than 闾値, the processing unit 42 determines that there is no operation input corresponding to the tilting area. The processing unit 42 performs such a determination in each detection area. As described above, the processing unit 42 is configured to detect the machine operation input when it is determined that there has been a machine operation input for each detection area, and to detect the position change operation input when it is determined that there has been a position change operation input. The information input by the machine operation detected by the processing unit 42 is output from the processing unit 42 to the determination unit 5. The information input by the position changing operation detected by the processing unit 42 is output from the processing unit 42 to the distance adjusting unit 6. The determination unit 5 includes a storage unit 51, a processing unit 52, and an output unit 53. The memory unit 5 pre-memorizes the correspondence between the machine operation input of the user p and the operation content of the machine 9. The processing unit 52 uses, for example, a microprocessor of a computer as a main constituent element, and the memory unit 5] acquires and determines an operation content corresponding to the machine operation input detected by the detecting unit 4. The processing unit 52 controls the output unit 53 to output the information of the determined operation content to the device 9. The distance adjustment unit 6 includes a fixed plate 61, a linear motion guide, a feed screw 63, a pulley 64, a pulley belt 65, a motor 66, and a control unit 67, and is configured to move the monitor. Drive. The monitoring benefit 1 is fixed to the fixed plate 61. The linear motion guide 62 is supported by the fixing plate 61 10/30 201205354. The motor 66 is an electronic motor that is driven from the adjustment unit 6. The pulley 64 and the pulley belt 65 transmit the rotational driving force of the motor 66 to the feed screw 63. The control unit 67 uses, for example, a microprocessor of a computer as a main component, and controls the motor 66 in accordance with information input from the detecting unit 4. As described above, the distance adjusting unit 6 converts the rotational driving force generated by the motor 66 into a linear motion by the feed screw 63, thereby realizing the movement of the monitor 1 in the vertical direction (the direction of the arrow in Fig. 1). Further, the computer used for the control unit 67 may be a general-purpose computer such as a personal computer or a dedicated computer. As described above, when the information input by the position changing operation is input by the detecting unit 4, the distance adjusting unit 6 can move the monitor 1 up and down in accordance with the information input operation of the position changing operation. Once the monitor 1 moves up and down, the optical distance a (refer to FIG. 14) between the operation face A on the monitor 1 and the concave mirror 2 changes, and the optical distance b between the real image B of the face and the concave mirror 2 is operated. (Refer to Figure 14) will change. However, the range of movement of the monitor 1 is limited to the optical distance a between the operation face A and the concave mirror 2, which is longer than the focal length f of the concave mirror 2. Specifically, when the position change operation input for bringing the real image B of the operation face closer to the user P side is performed, the distance adjustment unit 6 moves the monitor 1 to be lower than the current state, and causes the operation face A and The optical distance a between the concave mirrors 2 is shortened. Thereby, the optical distance b between the real image B of the operation face and the concave mirror 2 becomes long, and the real image B of the operation face is displayed closer to the user P side than is conventionally known. On the other hand, when the position change operation input for moving the real image B of the operation face away from the user P is performed, the distance adjustment unit 6 moves the monitor to be higher than the current state, and the optical distance a is made longer. Thereby, the optical distance b becomes shorter, and the real image B of the operation screen is displayed farther away from the user P than is conventionally known. 11/30 201205354 " Next, the operation of the operation of the present embodiment will be described. First, the monitor 丨 shows the operation face Λ 'Concave sharp 2 is formed so that the operation: the face image 丨 3 appears in the space and is displayed to the user). After that, ^ = 1) looks at the real image of the operation screen, and touches the touch panel's essentials. The detecting unit 4's processing unit 42 detects the input of the user using the photographic image of the photographing unit 。. After the decision: 'The processing unit 52 is the operation content of the machine operation input obtained by the Chengsuke 5并 and the mosquito dragon detected by the detective. The information of the determined operation contents is output from the output unit 53 to the machine 9. Further, the processing unit 42 of the detecting unit 4 outputs the information input from the position changing operation to the distance adjusting unit 6 when the positional change operation input is detected by the photographing image of the photographing unit 4. The control unit 67 of the distance adjusting unit 6 moves the monitor in accordance with the information input from the position changing operation of the detecting unit 4, and the user P can automatically solve the position of the real image β of the operation screen to suit his or her own vision state. position. - Next, an example of use of the operating device of the present embodiment will be described. First, the first use example will be described using the circle 3, and the operation device of the present embodiment is used in the case of a bathroom or a shower room. In other words, the third example of use is the warm water of the shower (four) device _ bathroom with a payout. The operating device is built into the wall w of the bathroom (Lin bathroom). According to the first use example, the water from the shower head S passes through the front of the user p, and even if the operating device is not disposed near the user P, the operation surface can be formed closer to the installation location of the operating device. Real image B. Thereby, even if the user p does not wear glasses or the visibility of the contact lens is low, the information of the operation face A can be understood by viewing the real image B of the face. Next, the use example of 苐2 will be described using FIG. 4', and the present embodiment 12/30 201205354 昍二-device is used in the kitchen. In other words, the second use case is meant to be a device. In the kitchen, the device is required near the conditioner (user Ρ): air and high temperature. In addition, the conditioner is in direct contact with the fout in the conditioning. However, the operation in accordance with the present embodiment is sufficient to operate the operation of the operation, such as the temperature of the furnace, without directly contacting the operation device. In addition, the shell image B of the dough can also display recipes for cooking. The use case of 0, 3, and 3 will be described using FIG. 5. However, the present embodiment is used for, for example, an ATM of a bank or an authentication device of a self-locking door, etc., and the device displays: information of high confidentiality' In order to carry out the password round of dreams, the wood is recognized. According to the third use example, the user P can operate at a position closer to the operation than the π position, and since the real image package of the county f picture = high directionality, it can be set so that others cannot easily see the operation surface. Resources and input. According to the operation device of the present embodiment, the real image β of the operation can be called the space between the installation place of the operation device and the user P, and therefore the information frequency of the operation specifying device 9 can be used. It is closer to the position of the user ρ than the above-mentioned setting place. In this way, the user ρ can be operated in the vicinity with the user's ρ. According to the operation device of the present embodiment, the directivity of the operation screen can be improved, so that the real image angle of the operation screen can be visually recognized, and the information of the operation screen can be displayed only to the user. Further, in accordance with the operation of the present embodiment, the optical distance a between the distance adjusting portion operation screen A and the concave mirror 2 is changed within a range longer than the focal length f of the concave surface, whereby the operation of the face can be made. Easy to move, so can you follow the user? And the change operation is written in 13/30 2〇12〇5354. The detected device can change the actual image of the operation according to the preference of the measurement unit 4, and the operation device of the user's face mirror can be used to allow the user to P by the half mirror 3 and the concave Identifying the image of the operation screen: : Preventing the operation of the face A itself becomes an obstacle.七:: 'The operation of the goods in the form of operation 1 contact operation 尽 Λ to operate ^ m user ^ _ not straight is difficult to directly touch the operation screen Λ, or two prisoners use * P can not touch operation 4 " In the case where the money operation wheel is born, it can also be used as follows: the chemical person's operation device does not have an unnecessary function. The dragger makes a round and changes the optical distance a. <• The operation μ of the bit change example of the real image B is also the ^== of the present tilt mode. The real image of the real image appears on the operation == gate:: Therefore, the above setting place for operating the designated machine 9 can be made closer. The location of the user's embarrassment, the user P can operate and input in the vicinity. Moreover, the <two fruit' is the directivity of the real image B of the picture, so it is possible to limit the angle of view of the recognizable gold = image B In the following embodiments 2 and 3, the following can be seen as a variation of the embodiment, and a planar object such as paper is operated instead of the operation. Picture A:=:y 9 information display ", can also use stereo objects. Ping 2 =: 14/30 201205354 Connected or indirectly installed at a sufficient distance. Even when a flat object or a fixed plate of 3 or 6 is used, the operational split can be formed so that the real image of the moon is visible. Operating device; body (planar object, vertical space, so that information for operating the position 9 closer to the user P can be displayed than the user P can be displayed near the user P, It shows the directivity of the real image of the media. Therefore, because it can view the real image of the media, it can display the information of the identifiable information to the use of I i. 'Q颂 The information that the media has only Display: Use the following. The following forms: 2. The distance between the 3D and the concave mirror 2 between the three-dimensional distance and the concave mirror 2, and the three methods of the concave mirror 2. Operate the device and only move the monitor i. As a case of carving the door, you can also use Ff for you. The mirror drive unit replaces the distance word 6 or the distance surface. The operation of this variation By moving the concave image 2 to move the real image of the operation screen β. _, in order to enable the user to correctly observe the real image, the user's eye is relatively concave, and the 2: position is limited to a certain position. Therefore, when the concave mirror 2 is moved, the user's eye position must also be moved. Therefore, the above three methods are only the best and most practical when the monitor is moved. In other words, there is no need to move. In the eye position of the user, the distance adjusting unit 6 of the present embodiment is more excellent than the concave mirror driving unit, and the same applies to the second and third embodiments. Λ 15/30 201205354 In the variation, the monitor 1 can also be set to 1 differently from the operation device 1. According to the operation device of the present modification, the same operation as that of the operation of the present embodiment can be performed by using a commercially available monitor 作. The following embodiments 2 and 3 are also the same. (Embodiment 2) The operation device according to the second embodiment can change the optical distance a between the operation screen Λ and the concave surface sharp 2 in accordance with the visual condition of the user P, and in this case, the relationship between the system and the product.

It is to be noted that the same components as those of the operation device in the form of the goods are denoted by the same reference numerals and will not be described. The operation device of this embodiment includes a visual force measuring unit 7 as shown in Fig. 6 . The visual force measuring unit 7 is, for example, an infrared refractometer (automatic refractometer) or the like, which measures the visual state of the user P. The so-called visual acuity has a focus adjustment function (visual power) or a mesh hole reaction, and a converence. The so-called focus y function 'changes the refractive power of the crystal according to the distance between the crystal and the visual target' so that the image is always imaged on the web. The term "reaction" means that the pupil is adjusted in accordance with a stimulus such as a change in the amount of light. The so-called light wheel means that when the near-sighted visual target is viewed, the eye muscles are concentrated toward the inner side (nasal side) for the focus of the focus. The information of the visual state measured by the visual force measuring unit 7 is output to the distance adjusting unit 6. The memory unit 68 of the distance adjusting unit 6 of the present embodiment preliminarily stores the correspondence relationship between the optical distance a between the operation screen A and the concave mirror 2 and the visual state of the user p. In the control unit 67' of the present embodiment, when the self-viewing force measuring unit 7 inputs the attribute of the visual state, the unit 68 obtains the distance corresponding to the distance a of the optical (16) 201205354 of the upper (four) signal. Thereafter, the control unit 67 causes the monitor 値 to move the 取得 obtained by the memory unit 68 at the optical distance a. As a result, the optical distance a between the operation screen A and the concave mirror 2 changes in accordance with the visual state measured by the visual force measuring unit 7. Next, the operation of the operating device of this embodiment will be described. First, when the monitor 1 displays the operation face A, the concave mirror 2 is formed such that the real image B of the operation face appears in the space and is displayed to the user P. Thereafter, the visual force measuring unit 7 measures the visual state of the user P. The information of the visual state measured by the visual force measuring unit 7 is output from the visual force measuring unit 7 to the distance adjusting unit 6. The control unit 67 of the distance adjustment unit 6 acquires the optical distance a値 corresponding to the information input from the self-view strength measuring unit 7 by the storage unit 68. Thereafter, the control unit 67 moves the monitor 1 so that the actual optical distance a becomes the enthalpy obtained from the memory unit 68. Thereafter, the user P views the real image B of the operation face and performs an operation input. In the detecting unit 4, the processing unit 42 detects the machine operation input of the user P from the photographing image of the photographing unit 41. Thereafter, the decision unit 5 processing unit 52 acquires and determines the operation content corresponding to the machine operation input detected by the detecting unit 4 from the storage unit 51. The information of the determined operation contents is output from the output unit 53 to the machine 9. The use example of the operation device of the present embodiment is the same as the first to third use examples of the first embodiment, and the operation device can be used for an ATM or a self-locking door of a building in a bathroom or a kitchen or a bank. As described above, according to the operating device of the present embodiment, the distance adjusting unit 6 changes the optical distance a between the operation surface A and the concave mirror 2 in accordance with the visual state measured by the visual force measuring unit 7, whereby the real image B of the operation screen is changed. Move to a position suitable for the visual state of the user P. 17/30 201205354 In addition, as a variant of this embodiment, it is not necessary to operate the function of the optical distance a. In other words, the operating device of the present modification changes the light step distance a between the operation screen A and the concave mirror 2 only in accordance with the vision state of the visual acuity f measuring portion 7. Even if the 曰 is the position of the present modification, the adjustment unit 6 can change the _ optical distance 3 of the operation mirror a 盥 the concave mirror 2 according to the (four) vision state measured by the force detection unit 7 so that the operation f surface The position of the read b moves to a niche suitable for the visual state of the user P.

It is also easy to recognize the operation and thus the operability of the user P. 18/30 201205354 (Embodiment 4) As shown in Fig. 8, the operation device of the fourth embodiment is in the same manner as the operation of the first embodiment (the dotted line in Fig. 8). It is to be noted that the same components as those in the first embodiment will be denoted by the same reference numerals and will not be described. In the monitor 13 of the present embodiment, the operation screen A: the surface U is displayed as a non-planar (the 曰_:, brother " imaging operation image of the 昼 surface compared to the case where the display surface is flat. The distortion of the mi ' & visual & ia is formed to face the spherical surface with a half mirror. In addition, as long as the operation can be reduced, the distortion of the display surface can be The spherical surface as described above; non: = concave mirror 23 and half mirror of the application form. In other words, the concave mirror 2a; 1 and the center of the mirror surface 21 of the mirror 2a are arranged so as to be projected into the concave surface. In the second view, the reflected light 33 is tilted on the upper side of Fig. 8). In other words, the direction is tilted. The half mirror 3a is divided into, and the Γ γ axis is opposite to the mirror 21 facing the normal 21 of the counterclock mirror, and the concave mirror half 3 is recessed 1aS, £;, : 3ι The angle formed by the optical axis of a is the sum of the light 33 projected onto the pupil of the concave mirror 2a. In addition, the middle: 22 reflects his splitter to replace the half mirror 3a. Lang has a concave shape of the + _ split surface and {it ^ ^ 戈 a spoon mirror 21 is formed into an elliptical surface (not '9/30 201205354 spherical surface'), which can reduce the poor image of the operation picture more than the spherical surface丨 3 twisted. In other words, the concave mirror 2a of the present embodiment is more capable of lowering the operation than the case of the spherical mirror, i is a shape in which the real image B is distorted, that is, a mirror (aspherical mirror). Further, the mirror surface 2 of the concave mirror 2a does not have to be an elliptical surface as described above, and may be an aspheric surface which is capable of reducing the distortion of the real image B of the operation screen more than the spherical surface. In the operation device of the present embodiment, as shown in FIG. 9, a monitor 丨a is disposed, and the monitor 1a can be two degrees L1 from the lowest position of the concave mirror 丨 82 mm to 丨85 面The length L2 of the concave mirror in the x-axis direction is 160 mm, and the length L3 in the Z-axis direction is 丨2 〇 mm. In the X-axis direction, the distance L4 between the concave mirror 23 (center point 22) and the half mirror 33 (point 32) is 50 mm. The distance L5 between the concave mirror 2a (center point 22) and the observation point 8 is 800 mm. Further, the height u, the lengths L2 and L3, and the distances L4 and L5 described above are merely examples, and are not limited to the above, and may be appropriately set depending on the application. As shown in Fig. 10, the real image (solid line in Fig. 1A) of the operating device of the present embodiment is flat compared to the display surface 9n of the monitor 91 as shown in Fig. 6 (refer to Fig. 7 Line) 'can reduce distortion. The half mirror 93 shown in Fig. 6 is raised from the half mirror 3 in the direction opposite to the mirror surface 921 (2丨) of the concave mirror 92 (2a) (the left side of Fig. 16). The half mirror 93 divides the light emitted from the monitor 91 into reflected light and transmitted light by a plane dividing surface 931. In addition, Fig. 0 is an example of the present embodiment, and shows that the radius of curvature of the display surface of the monitor 丨a is 50 mm, the constant of the conic curve k is -5.0, and the radius of curvature of the mirror surface 2 of the concave mirror 2a is 250 mm. The lattice distortion of the image when the conic constant k is -0.3. Fig. 〇(a) shows a case where the viewing distance L6 is 400 mm, and Fig. 10(b) shows a case where the viewing distance L6 is 4 mm 0 mm. 20/30 201205354 The radius of curvature and the conic constant k of the objective lens a and the concave mirror 2a are not limited to the above, and can be appropriately set according to the purpose. The dotted lines of Fig. 10 and Fig. 7 show the lattice distortion displayed by the display surface 1]. By the above description, when the half mirror 3a is configured to be projected to the reflected light 33 at the center point 22 of the mirror surface 21 of the concave mirror 2a, and the alignment normal 23 is tilted toward the monitor la side, by the monitor 〖a In the case where the display surface u is set to be a non-planar (spherical surface) 'the monitor 9 that is flat on the display surface 911', it is possible to reduce the distortion of the image B of the shank. As described above, in the operation device of the present embodiment, the concave mirror 2a and the half mirror 3a are arranged such that the reflected light 33 projected to the center point 22 of the mirror surface 21 of the concave mirror 2a is inclined toward the monitor 1 side with respect to the normal line 23, and is monitored. The display 11 of the device]a is formed as a non-planar surface. As a result, in the operating device of the present embodiment, the twist W1 of the device can be made thin without increasing the distortion of the real image B of the operation surface. In other words, the operation device of the present embodiment can display the image B closer to the operation face A as a visual target without causing the user p to find the distortion of the visual target, and at the same time, compared with the implementation of the shape The width W2 of the operating device (dotted line in Fig. 8) of 1 can make the width W1 of the device thin. In the operation of the present embodiment, the display surface 11 of the monitor &&> is oriented in a convex shape on the side opposite to the half mirror 3a, whereby the torsion oil of the visual target can be more easily reduced.

The split surface 3 of the half mirror 3b of the present embodiment is formed to be non-planar (curved surface) in comparison with the case where the split surface is flat to reduce the distortion of the image B of the operation face imaged by the concave mirror 2b. Specifically, the split surface 3 of the half mirror 3b faces the opposite side of the concave mirror 2b and is formed into a convex spherical surface. Further, the division surface 31 may be a non-planar surface other than the spherical surface as long as it is a distortion that can reduce the real image B of the operation surface. The concave mirror 2b and the half mirror 3b of this embodiment are arranged as shown in Fig. 。. In other words, the concave mirror 2b and the half mirror 3b are arranged to be reflected light 23 projected to the center point 22 of the mirror surface 2 of the concave mirror 2b, and aligned with the normal 23 in the center point 22 toward the monitor side (upper side of FIG. 11) Come to tilt. In other words, the reflected light 33 is around the Y-axis of Fig. ,, and the normal 23 is inclined toward the counterclockwise direction. The split surface 31 of the half mirror 3b is erected in a direction (left side in Fig. 1A) opposite to the mirror surface 2' of the concave mirror 2b than the half mirror 3. The half mirror 3b is disposed as described above for the concave mirror 2b, and is disposed relative to the monitor 为 at an angle Θ2 between the line 34 of the dividing surface 31 and the optical axis of the monitor 1 at the point 32 of the dividing surface 31. Below 45°. The point 32 on the dividing surface 31 is a point generated by the reflected light 33 projected to the center point 22 of the mirror surface 2] of the concave mirror 2b. Alternatively, another splitter having a split face of the above shape may be employed instead of the half mirror 3b. The mirror surface 21 of the concave mirror 2b of the present embodiment is formed into an elliptical surface (aspherical surface) so that the real image B distortion of the operation surface can be reduced more than the spherical surface. In other words, the concave mirror 2b of the present embodiment is a shape that is distorted by the real image B of the spherical mirror, that is, the elliptical mirror (aspherical ball: in addition, the mirror surface 21 of the concave mirror 2b does not have to be as As described above, the circular surface of the operation surface can be reduced in comparison with the spherical surface. The operation device of the present embodiment, as shown in Fig. 12, is equipped with a visual state 1 's monitor. The la system can be moved between 182 s and 185 mm from the lowest position L1 of the concave mirror 2|3, and the length L2 of the concave mirror % = direction is 16 〇 mm, and the length L3 of the Z-axis direction is 丨 2 〇 m In the X-axis direction, the distance L4 between the concave mirror 2b (center point 22) and the half mirror 3b (point 32) is 50 mm, and the concave mirror 2b (center point 22) and the observation point 8 are 800 mm from the tank L5. The height l], the long-length L], and the distances L4 and L5 are only examples, and are not limited to the above-mentioned conditions, and can be appropriately set according to the use of the display. As shown in Fig. 13, the embodiment is The real image in the operation device (the solid line in FIG. u) is flat compared to the division surface 931 of the half mirror 93 shown in FIG. 16 (refer to The solid line of 17 can reduce the distortion. In addition, in the present embodiment, the split surface 3 of the half mirror 3b is displayed: the radius of the radius is 500 〇 mm, the conic constant k_5 〇〇, the concave mirror 沘The curvature radius of the = 2 is 250 mm, the conic constant k is _ 〇 78: the lattice distortion of the real image, Fig. 13 (8) is the case where the viewing distance L6 is 4 〇〇 mm, and Fig. 13 (8) is the viewing distance Lu4 〖 0 mm. The curvature radius and the _curve constant k of the monitor 1 and the concave mirror 2b are not limited to the above-described enthalpy, and are appropriately set according to the application. The broken lines in FIGS. 13 and 17 show the lattice displayed by the display surface 11. According to the above, when the half mirror 3b is configured to be projected to the reflected light 33 at the center point 22 of the mirror surface 23/30 201205354 2丨 of the concave mirror 2b, and the alignment normal 23 is tilted toward the side of the monitor, The case where the split surface 3丨 of the semi-sharp 3b is a non-planar (spherical surface) is smaller than the case where the split surface 93 is a flat half mirror 93. The distortion of the image B of the operation surface can be reduced. In the operating device of this embodiment, the concave mirror 2b and the semi-sharp 3b are arranged to be projected to the concave The reflected light 33 of the center point 22 of the mirror surface 2 of the mirror 2b is inclined toward the monitor 丨恻, and the dividing surface 3丨 of the half mirror 3b is formed to be non-planar. Thereby, the operating device of the present embodiment The width W of the device can be thinned without increasing the distortion of the real image B of the operation surface. In other words, the operation device of the present embodiment can detect the distortion of the visual target without letting the user know. The real image B closer to the operation screen A is displayed as a visual target, and the width w/1 of the apparatus can be made thinner than the width W2' of the operation device (the broken line in the figure) of the embodiment. In particular, in the operation device of the present embodiment, the division surface 31 of the half mirror 3b is formed in a convex shape toward the side opposite to the concave mirror 2b, whereby the distortion of the visual target can be more easily reduced. Further, in the operating device of the present embodiment, the mirror surface 21 of the concave mirror 2b is aspherical, whereby the distortion of the visual target can be more easily reduced. Further, in the present embodiment, the distance adjusting unit 6 can also change the optical distance between the image formed by the half mirror 3b and the concave mirror 2b within a range longer than the focal length of the concave mirror 2b. The detecting unit 4 of each embodiment can also detect the user by using the output of two position detecting sensors (not shown). The 3-dimensional coordinates in the actual space at the position where the finger is operated. For example, when the camera is used as a position detecting sensor, the detecting unit 4 recognizes the fingertip portion of the user p in the image with 24/30 201205354 images for each of the two images captured by the respective cameras, and seeks The coordinates of the fingertip part in the image. The detecting unit 4 of the coordinate in the image is obtained by determining the coordinate range corresponding to the coordinate of the obtained coordinate in the actual space according to the arrangement of the camera or the characteristics of the lens, and the actual image is obtained for the two images. The position where the coordinate range on the space is repeated is set as the 3-dimensional coordinate of the position where the user p operates with the finger in the intersecting space.
