DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An example of a working apparatus according to the present invention will be described in detail below with reference to the drawings. Note that the isolator 1, which is an example of a working apparatus according to the present invention, described below is an example of the working apparatus according to the present invention, and the present invention is not limited to the embodiments described below.

[0010] [Embodiment 1] An isolator 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 6. The isolator 1 corresponds to an example of a working device.

[0011] 1 is a perspective view showing a schematic diagram of an isolator 1. The isolator 1 is installed, for example, in an institution (specifically, a research institute, a university, a hospital, etc.) that studies cells or microorganisms. Hereinafter, the institution in which the isolator 1 is installed is referred to as the installation target institution. The place in which the isolator 1 is installed is not particularly limited.

[0012] 2, when working, the user U stands in front of the isolator 1. Next, the user U puts on the gloves 22 of the isolator 1 and inserts his / her hands into the working area 203 of the isolator 1. Then, the user U performs a desired task within the working area 203.

[0013] In the following explanation, when explaining the structure of the isolator 1 and each of the members that make up the isolator 1, a Cartesian coordinate system (X, Y, Z) shown in each drawing may be used. The X direction corresponds to the front-to-rear direction of the isolator 1. The + side of the X direction corresponds to the front side of the isolator 1. The - side of the X direction corresponds to the rear side of the isolator 1.

[0014] Moreover, the Y direction corresponds to the left-right direction and width direction of the isolator 1. The + side of the Y direction corresponds to the right side when the isolator 1 is viewed from the front of the isolator 1. The - side of the Y direction corresponds to the left side when the isolator 1 is viewed from the front of the isolator 1.

[0015] The Z direction corresponds to the up-down direction of the isolator 1. The + side of the Z direction corresponds to the upper side of the isolator 1. The - side of the Z direction corresponds to the lower side of the isolator 1.

[0016] The isolator 1 includes an isolator body 2 and a non-contact input device 3 .

[0017] The isolator body 2 mainly includes a housing 20 , a partition wall 21 , and a globe 22 .

[0018] The housing 20 has a leg portion 201 and a working portion 202 .

[0019] The legs 201 are provided on the lower half of the housing 20. The legs 201 are installed on the floor of the engine in which the device is to be installed.

[0020] The working section 202 is provided in the upper half of the housing 20. The working section 202 is box-shaped and has an opening on the front surface.

[0021] The working section 202 has an upper wall portion 202a, a lower wall portion 202b (see FIG. 3), a right wall portion 202c, a left wall portion 202d, and a rear wall portion 202e.

[0022] The working section 202 has a working area 203 which is a space surrounded by an upper wall 202a, a lower wall 202b (see FIG. 3), a right wall 202c, a left wall 202d, and a rear wall 202e. The working area 203 has an opening at the front.

[0023] The partition wall 21 is a transparent plate-like member. The partition wall 21 closes the opening of the working area 203. In the present embodiment, the working area 203 is a space isolated from an external space 304 by the upper wall portion 202a, the lower wall portion 202b (see FIG. 3), the right wall portion 202c, the left wall portion 202d, the rear wall portion 202e, and the partition wall 21.

[0024] The partition 21 can also be regarded as a front wall of the housing 20. The material of the partition 21 may be, for example, glass or synthetic resin (for example, acrylic resin).

[0025] The partition section 21 is disposed between the working area 203 and a user U (see FIG. 2). In other words, the partition section 21 separates the external space 304 of the isolator 1 from the working area 203.

[0026] 2, during work, the user U is present in the external space 304 of the isolator 1 and in front of the isolator 1. The user U can view the work area 203 from the external space 304 through the partition wall 21.

[0027] Partition unit 21 has at least a portion thereof a reflection suppression area 210. Reflection suppression area 210 is the portion marked with diagonal grid in Figs. 3 and 4. Reflection suppression area 210 is an area in partition unit 21 that is disposed between user U and aerial image G1. Reflection suppression area 210 is an area for suppressing reflection by partition unit 21 to make it easier for user U to view aerial image G1 (see Figs. 3 and 4) within working area 203.

[0028] The reflection suppression region 210 may be a region in which reflection suppression treatment is applied to the surface of the partition portion 21. The reflection suppression treatment may be, for example, a moth-eye treatment. That is, the reflection suppression region 210 may have a moth-eye structure.

[0029] The anti-reflection treatment may be applied to either the front surface or the rear surface of the partition portion 21. In other words, the anti-reflection region 210 may be a region in which the anti-reflection treatment is applied to either the front surface or the rear surface.

[0030] The reflection suppressing region 210 may be a region in which an antireflection film (not shown) is provided on the surface of the partition portion 21. The antireflection film may be in the form of a film. Alternatively, the antireflection film may be formed of a film coated on the surface of the partition portion 21.

[0031] The material of the antireflection film may be a transparent material such as glass, a crystalline material, or a resin material (such as plastic).

[0032] Specifically, the material of the antireflection film may be optical glass such as FK03, FK5, BK7, SK20, SK14, LAK7, LAK10, LASF016, LASF04, SFL03, LASF08, NPH2, TAFD4, S-FPL53 (registered trademark), S-PSL5 (registered trademark), S-BSL7 (registered trademark), S-BAL50 (registered trademark), S-BSM14 (registered trademark), S-LAL7 (registered trademark), and S-LAL10 (registered trademark), Pyrex (registered trademark) glass, quartz, blue plate glass, white plate glass, Lumicera (registered trademark), Zerodur (registered trademark), fluorite, sapphire, acrylic, polycarbonate, polyethylene terephthalate, APEL (registered trademark), ZEONEX (registered trademark), ARTON (registered trademark), or the like.

[0033] The reflection suppression region 210 may be provided on the entire front or rear surface of the partition portion 21. In addition, different reflection suppression means may be implemented on the front and rear surfaces of the partition portion 21 in the reflection suppression region 210. For example, the reflection suppression region 210 may have an antireflection film on the front surface of the partition portion 21. In this case, the reflection suppression region 210 may have an antireflection treatment such as a moth-eye treatment applied to the rear surface of the partition portion 21.

[0034] Glove 22 is provided in partition 21. In the present embodiment, glove 22 has a left hand glove 221 and a right hand glove 222. Glove portions 22a (see FIG. 3) of left hand glove 221 and right hand glove 222 are each provided on the working area 203 side of partition 21. Insertion openings 22b of left hand glove 221 and right hand glove 222 open to the exterior space 304 side of partition 21.

[0035] 2, the user U inserts the left hand LH and the right hand RH of the user U into the insertion openings of the left glove 221 and the right glove 222 from the external space 304 side. The user U can access the working area 203 via the left glove 221 and the right glove 222. The user U performs a desired task in the working area 203 via the left glove 221 and the right glove 222.

[0036] The isolator 1 of this embodiment has various configurations that general isolators have in addition to the configurations described above. The isolator 1 has an adjustment means (not shown) for adjusting the environment of the working area 203 to a desired environment.

[0037] The adjustment means may include, for example, a temperature adjustment means (specifically, a heater). The temperature adjustment means has a function of adjusting the temperature of the working area 203 to a desired temperature.

[0038] The adjusting means may include, for example, a humidity adjusting means (specifically, a humidifier and a dehumidifier). The humidity adjusting means has a function of adjusting the humidity in the working area 203 to a desired humidity.

[0039] The adjusting means may include, for example, a concentration adjusting means. The concentration adjusting means has a function of adjusting the gas concentration (for example, oxygen concentration, carbon dioxide concentration, and nitrogen concentration) in the air of the working area 203 to a desired concentration.

[0040] The conditioning means may include, for example, an air conditioning means. The air conditioning means has a function of purifying the air in the work area 203. The air conditioning means maintains the work area 203 in a so-called clean state. The air conditioning means may include, for example, an exhaust means and an intake means.

[0041] The exhaust means exhausts air from the work area 203 to the external space 304. The exhaust means may have a filter that purifies the air from the work area 203. The intake means takes air from the external space 304 into the work area 203. The intake means may have a filter that purifies the air from the external space 304.

[0042] The isolator 1 may also include a disinfecting and cleaning means. The disinfecting and cleaning means has a function of disinfecting and cleaning the working area 203. The disinfecting and cleaning means disinfects the working area 203 by spraying, for example, hydrogen peroxide vapor into the working area 203.

[0043] The disinfecting and cleaning means also disinfects the working area 203 by, for example, irradiating the working area 203 with ultraviolet light. The disinfecting and cleaning means disinfects the working area 203 by, for example, heating the air in the working area 203 with a heater.

[0044] Next, a description will be given of the non-contact input device 3. The non-contact input device 3 forms an aerial image G1 that accepts input from the user U in the working area 203. The non-contact input device 3 corresponds to an example of an image forming device.

[0045] The non-contact input device 3 is supported by a housing 20. A specific configuration of the non-contact input device 3 will be described with reference to Fig. 4.

[0046] The non-contact input device 3 is a device equipped with a so-called aerial display. The aerial display can project information and images in the air.

[0047] Such a non-contact input device 3 is used as a terminal for the user U to input information or a terminal for the user U to obtain information.

[0048] In this embodiment, non-contact input device 3 is used as a terminal for user U to control the display of display 36 described below. User U can input to control the display of display 36 via aerial image G1 displayed in work area 203. .

[0049] In addition, the description of the non-contact input device 3 also uses the orthogonal coordinate system (X, Y, Z) shown in Fig. 4. The orthogonal coordinate system (X, Y, Z) shown in Fig. 4 corresponds to the orthogonal coordinate system (X, Y, Z) shown in Figs. 1 to 3.

[0050] The X direction corresponds to the front-rear direction of the non-contact input device 3. The +X direction side corresponds to the front side of the non-contact input device 3. The -X direction side corresponds to the rear side of the non-contact input device 3.

[0051] Moreover, the Y direction corresponds to the left-right direction and the width direction of the non-contact input device 3. The + side of the Y direction corresponds to the right side when the non-contact input device 3 is seen from the front of the non-contact input device 3. The - side of the Y direction corresponds to the left side when the non-contact input device 3 is seen from the front of the non-contact input device 3.

[0052] The Z direction corresponds to the up-down direction of the non-contact input device 3. The +Z direction side corresponds to the upper side of the non-contact input device 3. The -Z direction side corresponds to the lower side of the non-contact input device 3.

[0053] The non-contact input device 3 includes a housing 31, a display unit 32, an imaging element 33, a light adjustment unit 34, an input detection unit 35 (see FIG. 5), a display 36, and a control unit 37.

[0054] The non-contact input device 3 according to this embodiment is a so-called horizontally placed non-contact input device. In the case of a horizontally placed non-contact input device, the aerial image G1 is displayed above the non-contact input device 3, as shown in FIG. 4. In this embodiment, the horizontally placed non-contact input device is disposed below the user U in FIG. 4. The aerial image G1 is displayed above the non-contact input device 3. However, the horizontally placed non-contact input device may be disposed above the user U in FIG. 4. In this case, the aerial image G1 may be displayed below the non-contact input device 3. Note that the non-contact input device is not limited to the horizontally placed non-contact input device.

[0055] The non-contact input device may be a so-called vertically-placed non-contact input device. A vertically-placed non-contact input device has a configuration similar to that of the non-contact input device 3 shown in Fig. 4, rotated 90° clockwise in Fig. 4 and turned upside down. In the case of a vertically-placed non-contact input device, the aerial image G1 is displayed in front of the non-contact input device 3.

[0056] The vertically-placed non-contact input device may be disposed on the left side as viewed by the user U in Fig. 4. In this case, the aerial image G1 may be displayed on the right side of the non-contact input device 3. The vertically-placed non-contact input device may be disposed on the right side as viewed by the user U in Fig. 4. In this case, the aerial image G1 may be displayed on the left side of the non-contact input device 3.

[0057] The housing 31 is box-shaped and is a member for housing or supporting the elements 32 to 37 that constitute the non-contact input device 3. In the case of this embodiment, the housing 31 is in the shape of a rectangular parallelepiped that is long in the front-rear direction.

[0058] The housing 31 is disposed below the working section 202 of the isolator body 2. Specifically, the housing 31 is disposed below the bottom wall section 202b of the working section 202. The top surface of the bottom wall section 202b and the top surface of the imaging element 33 described below are disposed on approximately the same plane.

[0059] However, the shape of the housing is not limited to the shape of the housing 31 of this embodiment. The shape of the housing may be appropriately determined depending on the environment in which the non-contact input device 3 is installed. The shape of the housing 31 is not limited to a box shape. The shape of the housing 31 may be various shapes that can accommodate or support each of the elements 32 to 37 that configure the non-contact input device 3.

[0060] Moreover, the case 31 may be omitted. Instead of the case 31, the housing 20 may house or support the elements 32 to 37 that constitute the non-contact input device 3.

[0061] The display unit 32 may be, for example, various displays (for example, a liquid crystal display) that display images. The display unit 32 is supported by the housing 31 via a support portion 310. The display unit 32 faces diagonally upward and rearward toward the imaging element 33 described below.

[0062] Specifically, the display unit 32 is supported by the support portion 310 in a state in which the front end of the display unit 32 is inclined at a predetermined angle θ1 in a direction approaching the imaging element 33 described below with respect to a virtual line α1 parallel to the horizontal direction. In the case of this embodiment, the predetermined angle θ1 is 45°.

[0063] The light of the display image displayed by display unit 32 is focused as an aerial image G1 on imaging surface S by imaging element 33, which will be described later. Aerial image G1 corresponds to an example of a real image. Imaging surface S is a virtual area that exists in the air outside housing 31. In this embodiment, imaging surface S exists in working area 203.

[0064] The position of imaging plane S (i.e., the position of aerial image G1) in working area 203 is not particularly limited. However, the position of imaging plane S (i.e., the position of aerial image G1) is preferably a position in working area 203 that does not interfere with the work of user U.

[0065] Furthermore, the position of imaging plane S (i.e., the position of aerial image G1) is desirably a position in working area 203 that can be reached by the hand of user U. If user U is right-handed, the position of imaging plane S (i.e., the position of aerial image G1) is desirably a position in working area 203 that can be reached by the right hand RH of user U (see FIG. 6).

[0066] Furthermore, if user U is left-handed, the position of imaging plane S (that is, the position of aerial image G1) is desirably a position in working area 203 that can be reached by user U's left hand LH (see FIG. 6).

[0067] Of the light of the display image displayed by display unit 32, the light that is imaged as aerial image G1 on imaging surface S by imaging element 33 is also referred to as image-target light. The light of the display image displayed by display unit 32 also includes light other than the light that is imaged as aerial image G1 on imaging surface S by imaging element 33 (hereinafter also referred to as non-image-target light).

[0068] The imaging surface S may be regarded as a virtual area having a size sufficient to form at least the aerial image G1. The area on the imaging surface S where the aerial image G1 is formed may also be referred to as an aerial image area.

[0069] Moreover, the imaging surface S is a virtual region that exists at a position that is plane-symmetrical to the display unit 32 with respect to the imaging element 33 (in other words, the virtual line α2). The virtual line α2 is a virtual line that passes through the imaging unit 33 and is parallel to the horizontal direction. The virtual line α2 also passes through the imaging element 33 and indicates a plane that is parallel to the imaging element 33.

[0070] Specifically, the imaging surface S is a virtual area inclined at a predetermined angle θ2 with respect to a virtual line α3 parallel to the horizontal direction in a direction in which the front end of the imaging surface S approaches the imaging element 33. In the case of this embodiment, the predetermined angle θ2 is 45°.

[0071] The display operation of the display unit 32 is controlled by a later-described control unit 37. The control process of the display unit 32 by the control unit 37 will be described later.

[0072] As shown in Fig. 4, imaging element 33 is a plate-shaped member. Imaging element 33 is arranged parallel in the front-rear and left-right directions. Imaging element 33 focuses the display image of display unit 32 on an aerial image region on imaging plane S as aerial image G1.

[0073] In this embodiment, imaging element 33 has a plurality of light reflecting surfaces (not shown). As shown in Fig. 4, light of a display image on display unit 32 is incident on imaging element 33 from the direction indicated by arrow A1. Hereinafter, the light of the display image incident on imaging element 33 may be referred to as "incident light related to the display image".

[0074] The incident light related to the display image includes light that is imaged as aerial image G1 on imaging surface S by imaging element 33 (i.e., light to be imaged). The incident light related to the display image also includes light other than the light to be imaged (i.e., light not to be imaged). Light not to be imaged may be considered as light that is not imaged as aerial image G1 on imaging surface S by imaging element 33.

[0075] Furthermore, the light of the display image emitted from the imaging element 33 may be referred to as "emitted light related to the display image."

[0076] The outgoing light related to the display image includes light that is imaged as aerial image G1 on imaging surface S by imaging element 33 (i.e., light to be imaged). The outgoing light related to the display image also includes light other than the light to be imaged (i.e., light not to be imaged). Light not to be imaged may be considered as light that is not imaged as aerial image G1 on imaging surface S by imaging element 33.

[0077] The incident angle of the light to be imaged in the incident light with respect to the display image is equal to the inclination angle θ1 with respect to the virtual line α1 of the display unit 32. In this embodiment, the incident angle of the light with respect to the display image is 45°.

[0078] In addition, the emission angle of the light to be imaged in the outgoing light for the display image is equal to the incidence angle of the light to be imaged in the incoming light for the display image. In this embodiment, the emission angle of the light to be imaged in the outgoing light for the display image is 45°.

[0079] The light adjustment unit 34 suppresses leakage of light other than the light to be imaged in the emitted light related to the display image into the air through the imaging element 33. Note that the light adjustment unit 34 does not need to suppress leakage of all light other than the light to be imaged in the emitted light related to the display image.

[0080] In addition, the light adjustment unit 34 passes light to be imaged in the emitted light related to the display image. In addition, the light adjustment unit 34 blocks light directed from the display unit 32 toward the user U in a using state (i.e., the user U in FIG. 4). The light directed from the display unit 32 toward the user U in a using state (i.e., the user U in FIG. 4) also corresponds to an example of light other than light to be imaged.

[0081] The light adjustment unit 34 is provided on the surface (sometimes referred to as the first surface) on the air side of the imaging element 33. Specifically, the light adjustment unit 34 is configured by a louver film. However, the light adjustment unit 34 is not limited to a louver film.

[0082] The configuration of the louver film is substantially the same as that of a conventionally known louver film, and therefore a detailed description thereof will be omitted. The light adjustment portion may be any of various members capable of realizing the same function as the louver film.

[0083] 4, light to be imaged out of the light that is emitted from imaging element 33 and enters light adjustment unit 34 is emitted from light adjustment unit 34. Then, the light to be combined that is emitted from light adjustment unit 34 is imaged on imaging surface S as aerial image G1.

[0084] On the other hand, light that is not to be combined out of the light that is emitted from the imaging element 33 and enters the light adjustment section is absorbed by the light adjustment section . That is, the light that is not to be imaged does not exit from the light adjustment section .

[0085] Furthermore, light directed from the display unit 32 toward the user U in use (that is, the user U in FIG. 4) is absorbed by the light adjustment unit . Therefore, the light directed from the display unit 32 toward the user U is not emitted from the light adjustment unit .

[0086] In this way, light directed from display unit 32 to user U is blocked by light adjustment unit 34, so that display unit 32 cannot be seen by user U in use. This makes it easy for user U to view aerial image G1. As a result, the work efficiency of user U is improved.

[0087] Input detection unit 35 (see FIG. 5) detects information (hereinafter referred to as operation input information) regarding an operation input to aerial image G1 from user U (see FIG. 4). In this embodiment, user U inputs an operation input for controlling the display of display 36 via aerial image G1.

[0088] 5, the input detection unit 35 sends the detected operation input information to the control unit 37. The input detection unit 35 is supported by the housing 31.

[0089] Input detection unit 35 is configured with a plurality of sensors (not shown). Input detection unit 35 detects, for example, information about a position in aerial image G1 operated by user U (also referred to as position information) as operation input information.

[0090] The position information may be, for example, information about coordinates in the aerial image G1 (also referred to as coordinate information). The coordinate information may be three-dimensional coordinates including coordinates in the X direction, coordinates in the Y direction, and coordinates in the Z direction.

[0091] Furthermore, input detection unit 35 may detect information regarding the input depth of a fingertip when user U operates aerial image G1 (also referred to as input depth information). The input depth information may include a distance that user U's fingertip passes through aerial image G1 when user U operates aerial image G1. Input detection unit 35 sends the detected input depth information to control unit 37.

[0092] The configuration of the input detection unit 35 is not particularly limited. The configuration of the input detection unit 35 may be various configurations that can realize the above-mentioned functions. In addition, the position where the input detection unit 35 is provided is also not particularly limited. The input detection unit 35 may be provided in various positions that can realize the above-mentioned functions. The operation input information, the position information, the coordinate information, and the input depth information may be collectively referred to as first information.

[0093] The internal display unit 36 ​​displays information. The internal display unit 36 ​​may be, for example, a liquid crystal display or an organic EL display. The internal display unit 36 ​​displays information related to the work. The internal display unit 36 ​​is supported by the casing 31 or the housing 20.

[0094] The internal display unit 36 ​​may be housed in a case (not shown). The case is preferably made of a material that is resistant to hydrogen peroxide and / or ultraviolet light. The internal display unit 36 ​​may also be embedded in the rear wall 202. In this case, the surface (i.e., the front surface) of the rear wall 202 and the surface (i.e., the front surface) of the light adjustment unit 34 or the imaging element 33 may be located on the same plane.

[0095] The information about the work may include, for example, information about the procedure of the work, information about the progress of the work, and information about the work area.

[0096] The information on the work procedure may include a detailed explanation of the work to be performed in each step. The user U can reliably perform the work correctly by performing the work while looking at the information on the work procedure displayed on the internal display unit 36. As a result, the safety and efficiency of the work are improved.

[0097] Furthermore, the information on the progress of the work may include information on the current progress of each step. By looking at the information on the progress of the work displayed on the internal display unit 36, the user U can recognize the current progress.

[0098] Furthermore, the information about the work area may include information about the environment of the work area 203. The information about the environment of the work area 203 may include, for example, the temperature of the work area 203, the humidity of the work area 203, the gas concentration of the work area 203, and the air condition of the work area 203 (in other words, the cleanliness level).

[0099] The user U can recognize the environment of the work area 203 by looking at the information about the work area displayed on the internal display unit 36. If the environment of the work area 203 deviates from the desired environment, the user U may drive the adjustment means of the isolator 1 so that the environment of the work area 203 becomes the desired environment.

[0100] The adjustment means may be the above-mentioned temperature adjustment means, humidity adjustment means, concentration adjustment means, and air adjustment means. The user U may input an operation input for driving the adjustment means via the aerial image G1. In other words, the aerial image G1 may be an operation input unit through which the user U inputs an operation input for controlling the adjustment means.

[0101] In this embodiment, the internal display unit 36 ​​is configured with a liquid crystal display or an organic EL display. However, the internal display unit 36 ​​may be an aerial image formed by an image forming device.

[0102] 5, the control unit 37 controls the operation of the display unit 32. The control unit 37 also controls the operation of the internal display unit 36. The control unit 37 is supported by the housing 31. The control unit 37 may actually be configured in such a way that a CPU, a ROM, a RAM, a HDD, etc. are connected via a bus, or may be configured as a one-chip LSI, etc. The control executed by the control unit 37 will be described below.

[0103] Controller 37 executes display control of aerial image G1. That is, controller 37 controls the display operation of display unit 32. Specifically, controller 37 executes display control of aerial image G1 based on information related to an operation input by user U of non-contact input device 3 to aerial image G1.

[0104] The control unit 37 acquires information regarding the operation input of the user U of the non-contact input device 3 to the aerial image G1 from the input detection unit 35. The information regarding the operation input of the user U of the non-contact input device 3 to the aerial image G1 is first information detected by the input detection unit 35 (specifically, operation input information, position information, coordinate information, and input depth information).

[0105] Control unit 37 controls the display operation of internal display unit 36. Specifically, control unit 37 executes display control of internal display unit 36 ​​based on information related to an operation input by user U of non-contact input device 3 to aerial image G1.

[0106] As described above, control unit 37 controls the display operation of display unit 32 and the display operation of internal display unit 36. Control unit 37 switches the control target depending on the type of aerial image G1.

[0107] Specifically, when aerial image G1 is an image that accepts input for controlling the display operation of display unit 32, the control target of controller 37 is display unit 32. On the other hand, when aerial image G1 is an image that accepts input for controlling the display operation of internal display unit 36, the control target of controller 37 is internal display unit 36.

[0108] Below, the operation of the non-contact input device 3 will be briefly described, and the functions and effects of the isolator 1 according to this embodiment will be described.

[0109] When the power of the non-contact input device 3 is turned on, the control unit 37 controls the display operation of the display unit 32. Then, a predetermined image is displayed on the display unit 32. The light of the image displayed on the display unit 32 is incident on the imaging element 33. Then, the light is emitted from the imaging element 33.

[0110] Then, the light emitted from imaging element 33 (specifically, the light to be imaged) is imaged as aerial image G1 on imaging surface S. In this embodiment, aerial image G1 is displayed at a predetermined position in working area 203.

[0111] 2, during work, the user U is present in the external space 304 of the isolator 1 and in front of the isolator 1. The user U inserts the left hand and the right hand of the user U into the insertion openings of the left glove 221 and the right glove 222 from the external space 304 side.

[0112] The user U can access the work area 203 via the left glove 221 and the right glove 222. Then, the user U performs a desired work in the work area 203 via the left glove 221 and the right glove 222.

[0113] While working, the user U visually recognizes the work area 203 from the external space 304 through the partition unit 21. In particular, in the case of this embodiment, the user U visually recognizes the work area 203 from the external space 304 through the reflection suppression area 210 of the partition unit 21.

[0114] 6 is a diagram showing a schematic view seen by a user U working. The user U looks at the work area 203 from the front and above the isolator 1 (in other words, the non-contact input device 3) as shown in FIG.

[0115] In this embodiment, the aerial image G1 is displayed slightly behind the area where the user U works, as shown in Fig. 6. The position of the aerial image G1 is within reach of the right hand RH and left hand LH of the user U. Thus, the user U can operate the aerial image G1 with the right hand RH or left hand LH. In this embodiment, the user U can input information in a non-contact manner via the aerial image G1 while working.

[0116] Incidentally, aerial image G1 is formed on imaging plane S (see FIG. 4) above imaging element 33 in working area 203. Imaging element 33 is indicated by a dashed line in FIG. 6. If another member (in other words, an obstacle) exists between imaging element 33 and imaging plane S, aerial image G1 will not be formed on imaging plane S.

[0117] Therefore, in this embodiment, isolator 1 may have a configuration that suppresses the installation of obstacles that impede the formation of aerial image G1 by non-contact input device 3 (specifically, imaging element 33). Such a configuration corresponds to an example of a suppression means.

[0118] Specifically, isolator 1 may have a configuration in which the space present above imaging element 33 in working area 203 is surrounded by a wall (not shown) as a suppression means. The height of the wall is preferably such that it does not interfere with the work of user U and does not reduce the visibility of aerial image G1.

[0119] Furthermore, the isolator 1 may have a configuration in which the imaging element 33 is arranged at an angle as a suppression means. If the imaging element 33 is arranged at an angle, the user U is less likely to place a device that will become an obstacle above the imaging element 33. As a result, it is possible to suppress the placement of an obstacle above the imaging element 33 that would prevent the imaging unit 33 from forming the aerial image G1.

[0120] As a suppression means, the isolator 1 may have a configuration in which the imaging element 33 is disposed on a side wall (specifically, the right wall portion 202c, the left wall portion 202d, or the rear wall portion 202e) of the working section 202. With such a configuration, it is possible to suppress the placement of an obstacle between the imaging element 33 and the imaging surface S that would prevent the imaging element 33 from forming the aerial image G1.

[0121] Furthermore, the isolator 1 may have a configuration in which a transparent cover that covers the imaging element 33 from above is provided above the imaging element 33 as a suppression means. The cover is preferably, for example, mountain-shaped or hemispherical. The cover is preferably configured so as not to interfere with the imaging of the aerial image G1 by the imaging element 33. If a mountain-shaped cover is placed above the imaging element 33, the user U is less likely to place a device that will become an obstacle above the imaging element 33. As a result, it is possible to suppress the placement of an obstacle above the imaging element 33 that will interfere with the imaging of the aerial image G1 by the imaging element 33.

[0122] Furthermore, the isolator 1 may have a configuration as a suppression means in which the imaging element 33 is disposed at a position higher than the portion of the working area 203 where the user U works. In the case of such a configuration, the user U is also less likely to place a device that will become an obstacle above the imaging element 33. As a result, it is possible to suppress the placement of an obstacle above the imaging element 33 that would prevent the imaging element 33 from forming the aerial image G1.

[0123] Furthermore, the isolator 1 may have, as a suppression means, a notification means for notifying the user U of the position of the imaging element 33. Specifically, the notification means may be configured to surround the position of the imaging element 33 with a laser or a light. Furthermore, the notification means may be configured to notify the user U by voice or display that an obstacle is placed above the imaging element 33.

[0124] The position of aerial image G1 may be, for example, right region 203a at the right end of working area 203 (see FIG. 6) or left region 203b at the left end of working area 203.

[0125] In this embodiment, internal display unit 36 ​​is disposed slightly behind the position at which aerial image G1 is displayed. The position of internal display unit 36 ​​may be determined as appropriate.

[0126] As described above, the user U visually recognizes the working area 203 from the external space 304 through the reflection suppression area 210 of the partition portion 21.

[0127] Reflection-suppressed area 210 is an area where reflection by partition section 21 is suppressed. This allows user U to clearly view aerial image G1 within working area 203. That is, according to isolator 1 of the present embodiment, the visibility of aerial image G1 can be improved. As a result, user U can work efficiently.

[0128] Moreover, while working, the user U can visually confirm information related to the work displayed on the internal display unit 36. Various information for improving work efficiency is displayed on the internal display unit 36. This allows the user U to work efficiently.

[0129] User U can also change the display of internal display unit 36 ​​while working by operating aerial image G1. In other words, user U can input an operation input for operating the display of internal display unit 36 ​​via aerial image G1.

[0130] Aerial image G1 then accepts operation input from user U. The operation input inputted via aerial image G1 is sent to control unit 37. Control unit 37 controls the display of internal display unit 36 ​​based on the received operation input.

[0131] Thus, in this embodiment, aerial image G1 is an operation input unit through which user U inputs operation input for controlling the display operation of internal display unit 36. User U does not need to directly operate the device when changing the display of internal display unit 36. Such a configuration can suppress contamination of devices in working area 203 and cross-contamination via equipment.

[0132] (Additional Note) Furthermore, isolator 1 may have an external display unit 5 (see FIG. 1) outside working area 203. The display operation of external display unit 5 may be controlled by control unit 37 of non-contact input device 3. External display unit 5 may display the same image as aerial image G1.

[0133] The external display unit 5 may be a contact-type touch screen. Alternatively, the external display unit 5 may be an aerial image formed by an image forming device. When the aerial image G1 in the working area 203 displays an image for controlling the display of the internal display unit 36, the external display unit 5 also displays an image for controlling the display of the internal display unit 36.

[0134] While working, the user U operates the external display unit 5 to input operation inputs to control the display on the internal display unit 36. The external display unit 5 sends the received operation inputs to the control unit 37. The control unit 37 controls the display on the internal display unit 36 ​​based on the operation inputs received from the external display unit 5.

[0135] In this way, user U can control the display of internal display unit 36 ​​by operating aerial image G1 or external display unit 5. With such a configuration, user U does not need to put on or take off gloves 22 in order to control the display of internal display unit 36.

[0136] Furthermore, the external display unit 5 may display the same image as the image displayed by the internal display unit 36 ​​in the work area 203. In this case, the external display unit 5 may be a liquid crystal display or an organic EL display. Furthermore, the external display unit 5 may be an aerial image formed by an image forming device. Furthermore, the isolator 1 may have an operation input unit (not shown) around the external display unit 5 that controls the display of the external display unit 5. The operation input unit may be a contact-type operation input unit or a non-contact type operation input unit such as an aerial image. Furthermore, the external display unit 5 may be controlled based on an operation input input input by the user U via the aerial image G1 displayed in the work area 203.

[0137] Furthermore, when implementing isolator 1 according to the above-described embodiment, it is preferable that working unit 202 and the inner surface of housing 31 are surfaces that are less reflective. Such a configuration makes it easier for user U to view aerial image G1. It is preferable that the inner surface of working unit 202 is made of a material that is less reflective and enhances contrast, such as black stainless steel.

[0138] The non-contact input device 3 may also have a fan (not shown) for cooling the display unit 32. The housing 31 may also have an opening (not shown) for discharging air heated in the housing 31 to the outside. The support part 310 for supporting the display unit 32 is preferably made of a material with good thermal conductivity. Instead of a fan for cooling the display unit 32, circulating air within the working device may also be used. For example, the display unit 32 may be cooled using an airflow formed by the exhaust means and / or intake means as the air adjustment means described above.

[0139] Furthermore, the working device according to the present invention is not limited to the isolator described in the above embodiment, and may be any of a variety of working devices in which a transparent partition is provided between a user and a working area in which the user performs work.

[0140] The working area does not have to be completely isolated from the external space. The working area may be in communication with the external space. Examples of working apparatuses in which the working area is not completely isolated from the external space include a safety cabinet and a clean bench. The partition may be disposed between the user and the working area during work. The partition may be housed in the housing of the working apparatus except during work. [Industrial Applicability]
