Title: Booth

Description:
TECHNICAL FIELD 
     The present invention relates to a booth. 
     Priority is claimed on Japanese Patent Application No. 2019-191478, filed Oct. 18, 2019, the content of which is incorporated herein by reference. 
     BACKGROUND ART 
     There is a technique in which a partition wall is provided around a desk top plate, of which an upper surface includes a work surface, to improve a work environment on a desk (for example, refer to Patent Document 1). However, in a configuration as disclosed in Patent Document 1, no partition wall is provided behind a worker who works while facing the desk top plate. Therefore, in a case where, for example, a monitor device is used on the desk top plate, contents displayed on the monitor device may be viewed by another person behind the worker. 
     With regard to this, Patent Document 2 discloses a booth that includes a partially cylindrical screen in which an entrance is formed, and a top plate attached to an inner side of the screen. In such a configuration, a space in which the top plate is provided is surrounded by the screen except for a portion corresponding to the entrance. Therefore, contents displayed on a monitor device used on the top plate are less likely to be viewed from behind a worker.

     Patent Document 2: Japanese Unexamined Patent Application, First Publication No. 2018-84032 
     SUMMARY OF INVENTION 
     Technical Problem 
     The booth as disclosed in Patent Document 2 can have a shape along a regular hexagonal prism, a shape along a regular octagonal prism, a shape along a circular column, or the like as a whole. In a case where the booth has a shape along a regular hexagonal prism, a regular octagonal prism, a circular column or the like, a dead space is formed between the booth and other fixtures, a wall surface or the like in a room where the booth is installed, which hinders effective use of an installation space where the booth is installed. 
     In addition, Patent Document 2 also discloses that the booth can have a shape along a rectangular parallelepiped or a cube. However, even when the booth has a shape along a rectangular parallelepiped or a cube, effective use of the installation space where the booth is installed is hindered if the size of the booth is increased for improvement of usability inside the booth. On the other hand, if the size of the booth is reduced, a space inside the booth decreases, which leads to a decrease in usability for a user. 
     An object of the present invention is to provide a booth in which it is possible to increase a space use efficiency in an installation space and to improve usability while limiting a workspace on a top plate from being viewed from behind a user. 
     Solution to Problem 
     In order to obtain the above object, an aspect of the present invention is a booth including: a booth main body that includes a first panel, a second panel, and a third panel, the first panel being erected on a floor surface, and the second panel and the third panel being connected to two end portions in a width direction of the first panel and extending in a thickness direction of the first panel in a state where the second panel and the third panel face each other in the width direction; a top plate that is provided in the booth main body and of which an upper surface includes a work surface; and an inclined panel that is connected to a first end portion of the third panel positioned on a side of the third panel distant from the first panel in a plan view, extends to be inclined to become farther from the first panel toward the second panel in the width direction, and forms an entrance into the booth main body between the inclined panel and a first end portion of the second panel positioned on a side of the second panel distant from the first panel. The top plate includes a panel side edge portion that extends along the first panel and the second panel, and a front edge portion that includes a first edge portion extending in a direction such that the first edge portion becomes closer to the first panel from a first end of the front edge portion positioned on the second panel side of the front edge portion toward the third panel in the width direction. 
     As described above, the front edge portion is provided with the first edge portion that becomes closer to the first panel from the first end on the second panel side of the front edge portion toward the third panel in a state where the panel side edge portion of the top plate extends along at least the first panel and the second panel. Accordingly, a user who uses the work surface on the top plate while facing the first edge portion of the top plate does not straight face the first panel and is caused to face a corner portion between the first panel and the second panel in the plan view. In this state, since the inclined panel is provided behind the user, a workspace on the top plate is limited from being viewed from behind the user. 
     In addition, since the booth main body has a rectangular shape in the plan view that is formed by the first panel, the second panel, and the third panel, a dead space can be limited from being formed between the booth main body and other fixtures, walls, and the like provided in an installation space for the booth. 
     In addition, since the inclined panel is inclined in the same direction as the first edge portion of the front edge portion of the top plate in the plan view, a decrease in the distance between the inclined panel and the front edge portion of the top plate is limited, and thus accessibility with respect to the inside and the outside of the booth main body is made favorable. Furthermore, the work surface of the top plate extends diagonally from the front edge portion toward the corner portion between the first panel and the second panel, and thus a large depth on the work surface as seen from the user can be secured. In addition, in a case where the user uses the work surface of the top plate while sitting on a chair, a space for accommodation of the legs of the user that is under the top plate can also be secured diagonally and widely from the front edge portion of the top plate to the corner portion between the first panel and the second panel. Accordingly, even if the booth main body is reduced in size, usability in the booth can be improved. 
     Therefore, it is possible to increase a space use efficiency in an installation space and to improve usability while limiting the workspace on the top plate from being viewed from behind the user. 
     In the booth of the aspect of the present invention, in the plan view, a first virtual line may connect the first end and a second end of the front edge portion positioned closest to the first panel, a second virtual line may be orthogonal to the first virtual line and may pass through a corner portion between the first panel and the second panel, and the inclined panel may be disposed on the second virtual line. 
     According to such a configuration, the inclined panel is positioned behind the user who uses the work surface on the top plate while facing the first edge portion of the top plate. Therefore, it is possible to reliably prevent the workspace on the top plate from being viewed from behind the user. 
     In the booth of the aspect of the present invention, the second end of the front edge portion may be separated from the third panel in the width direction, and the front edge portion may include a second edge portion that extends from the second end toward the third panel. 
     According to such a configuration, a work surface that extends between the second edge portion and a rear edge portion being along the first panel is formed on the third panel side of the top plate as seen from a worker who is positioned to face the first edge portion of the top plate. Accordingly, the space on the work surface of the top plate is widened, and usability for the worker is improved. 
     In the booth of the aspect of the present invention, the first end of the top plate may be disposed to be closer to the first panel than the first end portion of the second panel. 
     According to such a configuration, the second panel protrudes in a direction farther from the first panel than the first end of the top plate. Thereby, a line of sight from an area close to the second panel as seen from the worker can be blocked. Accordingly, usability for the worker is improved. 
     In the booth of the aspect of the present invention, the first edge portion of the top plate and the inclined panel may extend linearly in the plan view. 
     According to such a configuration, the first edge portion of the top plate and the inclined panel can be easily manufactured, and thus the booth can be provided at a lower cost. 
     In the booth of the aspect of the present invention, the inclined panel may extend to be parallel with the first edge portion of the top plate in the plan view. 
     According to such a configuration, since the inclined panel and the first edge portion of the front edge portion of the top plate are parallel with each other, a decrease in the distance between the inclined panel and the front edge portion of the top plate is limited, and thus a decrease in accessibility with respect to the inside and the outside of the booth main body can be limited. 
     In the booth of the aspect of the present invention, a panel width of the inclined panel from the first end portion of the third panel may be less than a width of the first edge portion of the top plate. 
     According to such a configuration, it is possible to limit a decrease in the distance between the inclined panel and the first end portion of the second panel caused by the panel width of the inclined panel being made excessively large. Accordingly, a decrease in accessibility with respect to the inside and the outside of the booth main body can be limited. 
     In the booth of the aspect of the present invention, each of the first end portion of the second panel and a tip end portion of the inclined panel positioned on the second panel side of the inclined panel may be inclined such that a panel width decreases from an outer surface facing an outside of the booth main body to an inner surface facing an inside of the booth main body in the plan view. 
     According to such a configuration, interference with respect to an inner surface side end portion of the tip end portion of the inclined panel or an inner surface side end portion of the first end portion of the second panel can be limited when an entrance into the booth main body or an exit from the booth main body is performed through the entrance. As a result, a decrease in accessibility with respect to the inside and the outside of the booth main body can be limited. 
     Effects of Invention 
     According to the aspect of the present invention, it is possible to increase a space use efficiency in an installation space and to improve usability while limiting a workspace on a top plate from being viewed from behind a user.

       FIG.  1    is a perspective view showing the overall configuration of a booth  1  according to the embodiment of the present invention.  FIG.  2    is a plan view of the booth  1 . 
     As shown in  FIGS.  1  and  2   , the booth  1  includes a booth main body  10 , an inclined panel  14 , and a top plate  20 A. 
     The booth main body  10  is installed on a floor surface F. The booth main body  10  is configured by combining a facing panel (a first panel)  11 , a right-side panel (a second panel)  12 , and a left-side panel (a third panel)  13 . The facing panel  11 , the right-side panel  12 , and the left-side panel  13  are erected in a direction orthogonal to the floor surface F. 
     In the following description, a right-left direction when the facing panel  11  is horizontally seen in a direction orthogonal to an inner surface  11   f  (a surface that faces the inside of the booth main body  10 ) thereof is referred to as a width direction Dw, a direction (a thickness direction of the facing panel  11 ) that is orthogonal to the inner surface  11   f  of the facing panel  11  and that is parallel with a horizontal plane is referred to as a front-rear direction Df, and a direction that is orthogonal to the width direction Dw and the front-rear direction Df is referred to as a vertical direction Dv. Furthermore, in the front-rear direction Df, the facing panel  11  side of the booth main body  10  is referred to as a rear side, and the opposite side thereto is referred to as a front side. In addition, in the following description, a “plan view” represents a case where the booth main body  10  is seen in a direction downward from above. 
     The facing panel  11  is erected on the floor surface F in the vertical direction Dv that is orthogonal to the floor surface F. The facing panel  11  has a rectangular plate shape that is long in the vertical direction Dv. 
     The right-side panel  12  is disposed on a first side (a right side) in the width direction Dw of the facing panel  11 . The right-side panel  12  has a rectangular plate shape that is long in the vertical direction Dv and is erected on the floor surface F. The right-side panel  12  is connected to a right end portion  11   a  of the facing panel  11 . The right-side panel  12  extends forward from the end portion  11   a  of the facing panel  11 . 
     The left-side panel  13  is disposed on a second side (a left side) in the width direction Dw of the facing panel  11 . The left-side panel  13  has a rectangular plate shape that is long in the vertical direction Dv and is erected on the floor surface F. The left-side panel  13  is connected to a left end portion  11   b  of the facing panel  11 . The left-side panel  13  extends forward from the end portion  11   b  of the facing panel  11 . In the present embodiment, the right-side panel  12  and the left-side panel  13  are orthogonal to the inner surface  11   f  of the facing panel  11  in a plan view and extend in parallel with each other. However, it is sufficient that the right-side panel  12  and the left-side panel  13  extend in the front-rear direction Df in a state where the right-side panel  12  and the left-side panel  13  face each other in the width direction Dw. 
     Each of the facing panel  11 , the right-side panel  12 , and the left-side panel  13  is configured of a panel body P having a similar structure. The panel body P includes, for example, a rectangular panel main body (not shown), frame materials Pe provided along the four sides of the panel main body, and a leg portion (not shown) provided on a lower side frame material and grounded on the floor surface F. Note that the material and the structure of the panel body P are not limited in any way, and a configuration other than a configuration as described above can be appropriately adopted. In addition, the facing panel  11 , the right-side panel  12 , and the left-side panel  13  may be integrated. 
     Inside the booth main body  10 , a booth interior space  100  with an opening  100   k  that faces forward is formed by being surrounded by the facing panel  11 , the right-side panel  12 , and the left-side panel  13 . In the present embodiment, the facing panel  11 , the right-side panel  12 , and the left-side panel  13  have an equal panel width Sp on a side thereof facing the booth interior space  100 . As a result, the booth main body  10  has a square shape in the plan view. However, the panel widths Sp of the panels  11 ,  12 , and  13  may be different from each other. 
     The top plate  20 A is provided in the booth main body  10 . The top plate  20 A has a plate shape and is provided along a horizontal plane orthogonal to the vertical direction Dv. An upper surface of the top plate  20 A constitutes a flat work surface  20   f.    
     As shown in  FIG.  2   , the top plate  20 A includes a panel side edge portion  21  and a front edge portion  22 A. The panel side edge portion  21  includes a rear edge  21   a  that extends in the width direction Dw along the inner surface  11   f  of the facing panel  11 , a right edge  21   b  that extends in the front-rear direction Df along an inner surface  12   f  of the right-side panel  12 , and a left edge  21   c  that extends in the front-rear direction Df along an inner surface  13   f  of the left-side panel  13 . The top plate  20 A is fixed by a bracket (not shown), a leg (not shown) standing up from the floor surface F, or the like in a state where the panel side edge portion  21  is aligned with the facing panel  11 , the right-side panel  12 , and the left-side panel  13 . Note that the panel side edge portion  21  may not be in contact with the inner surfaces  11   f  to  13   f  of the panels  11  to  13  facing the panel side edge portion  21  as long as the panel side edge portion  21  is close to the inner surfaces  11   f  to  13   f.    
     The front edge portion  22 A of the top plate  20 A includes a first edge portion  22   a  and a second edge portion  22   b.  The first edge portion  22   a  is positioned on a right side (the right-side panel  12  side) of the front edge portion  22 A with respect to the second edge portion  22   b.    
     The first edge portion  22   a  extends to be inclined rearward to become gradually closer to the facing panel  11  from a first end  22   e,  which is a right end, toward a second end  22   f,  which is a left end. In the present embodiment, the first edge portion  22   a  extends linearly in the plan view from the first end  22   e  to the second end  22   f.  The first end  22   e  of the first edge portion  22   a  constitutes a right end of the entire front edge portion  22 A. That is, the first end  22   e  is joined to the front end of the right edge  21   b.  In contrast, the second end  22   f  of the first edge portion  22   a  is separated from the left-side panel  13  in the width direction Dw. Note that the first end  22   e  is disposed behind a front-end portion (a first end portion)  10   b  (hereinafter, referred to as a booth right front-end portion  10   b ) of the right-side panel  12  by a predetermined length. 
     The second edge portion  22   b  extends leftward from the second end  22   f  of the first edge portion  22   a.  The second edge portion  22   b  extends linearly in the width direction Dw in the plan view and is orthogonal to the inner surface  13   f  of the left-side panel  13 . Note that the second end  22   f  of the first edge portion  22   a  and the second edge portion  22   b  constitute a rearmost portion of the front edge portion  22 A and are closest to the facing panel  11 . 
     The front edge portion  22 A of the top plate  20 A is formed such that a width W 1  thereof in a direction (a direction connecting the first end  22   e  and the second end  220  in which the first edge portion  22   a  extends is greater than a width W 2  of the second edge portion  22   b  in a direction (the width direction Dw) in which the second edge portion  22   b  extends. 
     In addition, the top plate  20 A is provided with, for example, a wire insertion portion  25  through which various wires that are connected to electric devices to be used on the work surface  20   f  are inserted. In addition, a lighting device  26  is provided above the work surface  20   f  of the top plate  20 A. The lighting device  26  is fixed to, for example, the facing panel  11  of the booth main body  10 . Note that the top plate  20 A or the booth main body  10  can be provided with various optional members other than the wire insertion portion  25  and the lighting device  26 . 
     In the booth interior space  100 , a chair C is provided at a position facing the first edge portion  22   a.  The chair C is configured to be rotatable around an axis extending in the vertical direction Dv. The chair C may be fixed to, for example, the floor surface F or may be able to travel on the floor surface F by casters or the like. In addition, the chair C may be supported by an arm or the like extending from the booth main body  10 . 
     The inclined panel  14  is connected to a front-end portion (a first end portion)  10   a  (hereinafter, referred to as a booth left front-end portion  10   a ) of the left-side panel  13 . The inclined panel  14  extends to be inclined forward (in a direction farther from the facing panel  11 ) and rightward from the booth left front-end portion  10   a.  A tip end portion  14   s  (an end portion distant from the booth left front-end portion  10   a ) of the inclined panel  14  is disposed with a distant from the booth right front-end portion  10   b.    
     Accordingly, an entrance  100   e  for entering and exiting the booth interior space  100  is formed between the tip end portion  14   s  of the inclined panel  14  and the booth right front-end portion  10   b.    
     In the present embodiment, the inclined panel  14  extends linearly in the plan view. The inclined panel  14  extends to be parallel with the first edge portion  22   a  of the top plate  20 A in the plan view. 
     A first virtual line L 1  connects the first end  22   e  and the second end  22   f  of the first edge portion  22   a  of the front edge portion  22 A, a second virtual line L 2  is orthogonal to the first virtual line L 1  and passes through a corner portion  10   c  between the facing panel  11  and the right-side panel  12 , and the inclined panel  14  is positioned on a second virtual line L 2 . In the present embodiment, the second virtual line L 2  intersects the inclined panel  14  at a portion positioned close to the tip end portion  14   s.  That is, the second virtual line L 2  intersects the inclined panel  14  at a portion that is closer to the tip end portion  14   s  than the middle portion in a direction in which the inclined panel  14  extends. However, it is sufficient that the second virtual line L 2  intersects the inclined panel  14  within a panel width S 1  of the inclined panel  14  (a length on an outer surface  14   g  of the inclined panel  14 ). Here, the inclined panel  14  and the top plate  20 A (the first edge portion  22   a ) may be formed such that an angle θ equal to or less than, for example, 45° is formed between the second virtual line L 2  and the inner surface  12   f  of the right-side panel  12  in the plan view. 
     In addition, the tip end portion  14   s  of the inclined panel  14  is formed to be inclined such that the length of the inclined panel  14  in the direction (a panel width direction) in which the inclined panel  14  extends gradually decreases from an end portion  14   u  of the tip end portion  14   s  on the outer surface  14   g  (a surface that faces the outside of the booth main body  10 ) side of the inclined panel  14  toward an end portion  14   t  of the tip end portion  14   s  on an inner surface  14   f  (a surface that faces the inside of the booth main body  10 ) side of the inclined panel  14 . Accordingly, the tip end portion  14   s  is provided with a tip end inclined surface  14   m  that is inclined with respect to the direction in which the inclined panel  14  extends. In an example shown in the drawing, the tip end inclined surface  14   m  extends in the front-rear direction Df. However, in the tip end inclined surface  14   m,  the end portion  14   t  on the inner surface  14   f  side may be positioned on the left of the end portion  14   u  on the outer surface  14   g  side and may be positioned on the right of the end portion  14   u  on the outer surface  14   g  side. 
     The booth right front-end portion  10   b  of the booth main body  10  is formed to be inclined such that a panel width of the right-side panel  12  in a direction (the front-rear direction Df) in which the right-side panel  12  extends gradually decreases from an end portion  12   u  of the booth right front-end portion  10   b  on an outer surface  12   g  (a surface that faces the outside of the booth main body  10 ) side of the right-side panel  12  toward an end portion  12   t  of the booth right front-end portion  10   b  on the inner surface  12   f  (a surface that faces the inside of the booth main body  10 ) side of the right-side panel  12 . Accordingly, the booth right front-end portion  10   b  is provided with a front-end inclined surface  10   t  of which the end portion  12   t  on the inner surface  12   f  side is positioned behind the end portion  12   u  on the outer surface  12   g  side. Note that the tip end portion  14   s  of the inclined panel  14  and the booth right front-end portion  10   b  may be flat surfaces extending in directions orthogonal to respective extending directions thereof. 
     In addition, the inclined panel  14  may be provided such that the panel width S 1  on the outer surface  14   g  from the booth left front-end portion  10   a  is less than the width W 1  of the first edge portion  22   a  of the top plate  20 A. In addition, the panel width S 1  of the inclined panel  14  may be equal to or less than ½ of the panel width Sp of the facing panel  11 . Accordingly, the width of the entrance  100   e  between the tip end portion  14   s  of the inclined panel  14  and the booth right front-end portion  10   b  is secured widely. 
     A user of the booth  1  as described above enters and exits the booth main body  10  (the booth interior space  100 ) through the entrance  100   e  formed between the tip end portion  14   s  of the inclined panel  14  and the booth right front-end portion  10   b.  The user sits on, for example, the chair C in the booth  1  and uses the work surface  20   f  on the top plate  20 A in a state of facing the first edge portion  22   a  of the top plate  20 A. At this time, the user does not straight face the facing panel  11  but straight faces the first edge portion  22   a  of the top plate  20 A. As a result, the user is caused to face a right end portion (the corner portion  10   c  between the facing panel  11  and the right-side panel  12 ) of the facing panel  11  in the plan view. 
     In this state, the inclined panel  14  is provided behind the user to block a view from behind the user. In addition, since the entrance  100   e  is formed in the right of the user, a feeling of blockage felt by the user can be limited. In addition, the user can visually recognize a person approaching from the right easily through the entrance  100   e.  In addition, the user inside the booth  1  is visually recognized easily when being viewed from the outside of the booth  1  through the entrance  100   e.    
     As described above, in the present embodiment, the booth  1  includes the booth main body  10  including the facing panel  11 , the right-side panel  12 , and the left-side panel  13 , the top plate  20 A, and the inclined panel  14  that extends from the booth left front-end portion  10   a  of the booth main body  10  to be inclined. The top plate  20 A includes the front edge portion  22 A including the first edge portion  22   a  that extends in a direction to become closer to the facing panel  11  from the first end  22   e  on the right-side panel  12  side of the front edge portion  22 A toward the left-side panel  13 . 
     According to such a configuration, since the front edge portion  22 A of the top plate  20 A is provided with the first edge portion  22   a,  the user who faces the first edge portion  22   a  of the top plate  20 A faces the corner portion  10   c  between the facing panel  11  and the right-side panel  12 . In this case, as seen from the user of the top plate  20 A, the inclined panel  14  is provided behind the user, and thus a workspace on the top plate  20 A is limited from being viewed from behind the user. 
     In addition, since the booth main body  10  has a rectangular shape in the plan view, a dead space being formed between the booth main body  10  and other fixtures, walls, and the like provided in an installation space in which the booth  1  is installed can be limited. 
     In addition, since the inclined panel  14  is inclined in the same direction as the first edge portion  22   a  of the front edge portion  22 A of the top plate  20 A, a decrease in the distance between the inclined panel  14  and the front edge portion  22 A of the top plate  20 A is limited, and thus accessibility with respect to the inside and the outside of the booth main body  10  is made favorable. Furthermore, the work surface  20   f  of the top plate  20 A extends diagonally from the front edge portion  22 A toward the corner portion  10   c,  and a large depth D (in a direction along the second virtual line L 2 ) on the work surface  20   f  as seen from the user can be secured. In addition, in a case where the user uses the work surface  20   f  of the top plate  20 A while sitting on the chair C, a space for accommodation of the legs of the user that is under the top plate  20 A can also be secured diagonally and widely from the front edge portion  22 A of the top plate  20 A toward the corner portion  10   c.  Accordingly, even if the booth main body  10  is reduced in size, usability in the booth  1  can be improved. 
     Therefore, according to the booth  1 , it is possible to increase a space use efficiency in an installation space and to improve usability while limiting a workspace on the top plate  20 A from being viewed from behind the user. 
     In the present embodiment, the inclined panel  14  is configured to be disposed on the second virtual line L 2  that is orthogonal to the first virtual line L 1  connecting the first end  22   e  of the front edge portion  22 A and the second end  22   f  of the front edge portion  22 A that is positioned to be closest to the facing panel  11 , and the second virtual line L 2  passes through the corner portion  10   c.    
     According to such a configuration, the inclined panel  14  is positioned behind the user who uses the work surface  20   f  on the top plate  20 A while facing the first edge portion  22   a  of the top plate  20 A. Therefore, it is possible to more reliably prevent the workspace on the top plate  20 A from being viewed from behind the user. 
     In the present embodiment, the front edge portion  22 A is configured to include the second edge portion  22   b  that extends from the second end  22   f  toward the left-side panel  13 . 
     According to such a configuration, the work surface  20   f  that extends leftward further than the second end  22   f  is formed on a left side of the top plate  20 A as seen from a worker facing the first edge portion  22   a.  Accordingly, a space on the work surface  20   f  of the top plate  20 A is widened, and usability for the worker is improved. 
     In the present embodiment, the first end  22   e  of the top plate  20 A is configured to be disposed in front of the booth right front-end portion  10   b  of the booth main body  10 . 
     According to such a configuration, the right-side panel  12  of the booth main body  10  protrudes rearward further than the first end  22   e  of the top plate  20 A. Thereby, a line of sight from an area close to the right-side panel  12  as seen from the worker can be blocked by the right-side panel  12 . Accordingly, usability for the worker is improved. 
     In the present embodiment, the first edge portion  22   a  of the top plate  20 A and the inclined panel  14  are configured to extend linearly in the plan view. 
     According to such a configuration, the first edge portion  22   a  of the top plate  20 A and the inclined panel  14  can be easily manufactured, and thus the booth  1  can be provided at a lower cost. 
     In the present embodiment, the inclined panel  14  is configured to extend to be parallel with the first edge portion  22   a  of the top plate  20 A in the plan view. 
     According to such a configuration, a decrease in the distance between the tip end portion  14   s  of the inclined panel  14  and the front edge portion  22 A of the top plate  20 A is limited, and thus a decrease in accessibility with respect to the inside and the outside of the booth main body  10  can be limited. 
     In the present embodiment, a configuration in which the panel width S 1  of the inclined panel  14  from the booth left front-end portion  10   a  is less than the width W 1  of the first edge portion  22   a  of the top plate  20 A is adopted. 
     According to such a configuration, it is possible to limit a decrease in width of the entrance  100   e  caused by the panel width S 1  of the inclined panel  14  being made excessively large. Accordingly, a decrease in accessibility with respect to the inside and the outside of the booth main body  10  can be limited. 
     In the present embodiment, the booth right front-end portion  10   b  of the right-side panel  12  and the tip end portion  14   s  of the inclined panel  14  are configured to be inclined such that the panel widths of the panels  12  and  14  decrease from the outer surfaces  12   g  and  14   g  toward the inner surfaces  12   f  and  14   f  in the plan view. 
     According to such a configuration, interference with respect to the end portion  14   t  on the inner surface  14   f  side of the tip end portion  14   s  of the inclined panel  14  or the end portion  12   t  on the inner surface  12   f  side of the booth right front-end portion  10   b  is limited at the time of an entrance into the booth main body  10  or an exit from the booth main body  10 , and thus a decrease in accessibility with respect to the inside and the outside of the booth main body  10  can be limited. 
     (Modification Examples of Embodiment) 
     Next, modification examples of the booth according to the present invention will be described. Note that in each modification example described below, the configuration of a front edge portion of a top plate is different from that of the front edge portion  22 A described in the above embodiment. 
     FIRST MODIFICATION EXAMPLE 
       FIG.  3    is a plan view of a booth  1 B according to a first modification example of the embodiment of the present invention. 
     As shown in  FIG.  3   , a second edge portion  22   c  of a front edge portion  22 B of a top plate  20 B provided in the booth  1 B extends to be inclined forward and leftward from the second end  22   f  of the first edge portion  22   a.  The second edge portion  22   c,  for example, extends to be orthogonal to the first edge portion  22   a  in the plan view. Note that a direction in which the second edge portion  22   c  extends may not be orthogonal to the first edge portion  22   a  in the plan view. 
     Even in a case where the front edge portion  22 B is formed in a V shape in the plan view as described above, it is sufficient that the inclined panel  14  is disposed on the second virtual line L 2  that is orthogonal to the first virtual line L 1  connecting the first end  22   e  and the second end  22   f  of the first edge portion  22   a,  and the second virtual line L 2  passes through the corner portion  10   c  between the facing panel  11  and the right-side panel  12 . In the first modification example of the present embodiment, a space on the work surface  20   f  of the top plate  20 A is widened on the left-side panel  13  side of the top plate  20 A as seen from a worker who is positioned to face the first edge portion  22   a  of the top plate  20 B, and thus usability for the worker is improved. 
     SECOND MODIFICATION EXAMPLE 
       FIG.  4    is a plan view of a booth  1 C according to a second modification example of the embodiment of the present invention. 
     As shown in  FIG.  4   , a front edge portion  22 C of a top plate  20 C provided in the booth  1 C has an arc shape protruding rearward in the plan view. Specifically, the front edge portion  22 C includes a first edge portion  22   p  and a second edge portion  22   q.  The first edge portion  22   p  is formed on a right side of the front edge portion  22 C with respect to the second edge portion  22   q.    
     The first edge portion  22   p  extends rearward to become gradually closer to the facing panel  11  from a first end  22   h,  which is a right end, toward a second end  22   i,  which is a left end, in the width direction Dw. In the present embodiment, the first edge portion  22   p  extends to be curved rearward from the first end  22   h  to the second end  22   i.    
     The second edge portion  22   q  extends to be curved forward from the second end  22   i  of the first edge portion  22   p  toward the left-side panel  13 . Therefore, the second end  22   i  of the first edge portion  22   p  is a portion of the front edge portion  22 C that is closest to the facing panel  11 . Note that the first edge portion  22   p  and the second edge portion  22   q  are formed to have an equal radius of curvature. However, the radiuses of curvature of the first edge portion  22   p  and the second edge portion  22   q  may be different from each other. 
     A first virtual line L 3  connects the first end  22   h  and the second end  22   i  of the front edge portion  22 C, a second virtual line L 4  is orthogonal to the first virtual line L 3  and passes through the corner portion  10   c  between the facing panel  11  and the right-side panel  12 , and the inclined panel  14  is disposed on the second virtual line L 4 . 
     THIRD MODIFICATION EXAMPLE 
     In addition, in the above-described embodiment and the two modification examples, the front edge portions  22 A to  22 C include the first edge portions  22   a  and  22   p  and the second edge portions  22   b,    22   c  and  22   q.  However, the present invention is not limited thereto. 
       FIG.  5    is a plan view of a booth  1 D according to a third modification example of the embodiment of the present invention. 
     As shown in  FIG.  5   , a front edge portion  22 D of a top plate  20 D provided in the booth  1 D includes only a first edge portion  22   s.  The first edge portion  22   s  extends rearward to become gradually closer to the facing panel  11  from a first end  22   j,  which is a right end, toward a second end  22   k,  which is a left end, in the width direction Dw. In this case, the second end  22   k  is a portion of the front edge portion  22 D that is closest to the facing panel  11 . In addition, in the present modification example as well, the first virtual line L 1  connects the first end  22   j  and the second end  22   k,  the second virtual line L 2  is orthogonal to the first virtual line L 1  and passes through the corner portion  10   c  between the facing panel  11  and the right-side panel  12 , and the inclined panel  14  is disposed on the second virtual line L 2 . 
     Other Embodiments 
     Hereinbefore, practical examples of the present invention and modification examples thereof have been described. However, the present invention is not limited to the practical examples and the modification examples. Configurations may be added, omitted, replaced or modified within the scope of the present invention. The present invention is not limited by the above description but only by the appended claims. 
     For example, in the above-described embodiment, each of the first edge portions  22   a,    22   p  and  22   s  of the top plate  20 A has a linear shape or a curved shape. However, the shape thereof may be, for example, a wavy shape or a curved shape protruding rearward in the plan view instead of the linear shape or the curved shape of the above embodiment. 
     In the above-described embodiment, a configuration in which the first ends  22   e,    22   h  and  22   j  of the top plates  20 A,  20 B,  20 C and  20 D are disposed behind the booth right front-end portion  10   b  has been described. However, the present invention is not limited thereto. The first end  22   e  of the top plate  20 A may be disposed at the same position as the booth right front-end portion  10   b  in the front-rear direction Df. 
     In the above-described embodiment, a configuration in which the panel side edge portion  21  of each of the top plates  20 A,  20 B,  20 C and  20 D includes the rear edge  21   a,  the right edge  21   b,  and the left edge  21   c  has been described. However, the present invention is not limited thereto. It is sufficient that the panel side edge portion  21  includes at least the rear edge  21   a  and the right edge  21   b  with the corner portion  10   c  interposed therebetween. 
     In the above-described embodiment, for example, a configuration in which the work surface  20   f  of the top plate  20 A is flat along a horizontal plane has been described. However, the present invention is not limited thereto. For example, the work surface  20   f  of the top plate  20 A may be inclined downward and toward the front edge portion  22 A, which is a user side edge portion. That is, it is sufficient that in the front edge portion  22 A, the first edge portion  22   a  extends to be inclined rearward to become gradually closer to the facing panel  11  from the first end  22   e,  which is a right end, toward the second end  22   f,  which is a left end, in the plan view. In addition, for example, the top plate  20 A may be configured to be able to be moved up and down. 
     In the above-described embodiment, the first edge portions  22   a  and  22   s  of the top plate  20 A and the inclined panel  14  are provided to be parallel with each other. However, the present invention is not limited thereto. The first edge portions  22   a  and  22   s  of the top plate  20 A and the inclined panel  14  may not be parallel with each other. 
     In the above-described embodiment, a configuration in which the inclined panel  14  is connected to the left-side panel  13  has been described. However, the inclined panel  14  may be connected to the right-side panel  12 . 
     In the above-described embodiment, the booth main body  10  has a square shape in the plan view. However, the booth main body  10  may have a rectangular shape that is long in the width direction Dw or the front-rear direction Df in the plan view. 
     In addition, it is possible to appropriately replace a component in the above-described embodiment with a well-known component within the scope of the present invention, and the above-described modification examples may be appropriately combined with each other.
