In the following description, the same reference numerals are assigned to similar components. 【0011】 <Overall Configuration> Referring to Figures 1 to 4, a stationary device 1 according to one embodiment will be described. The stationary device 1 is a device used by being placed on a mounting surface such as a table, floor, or shelf. The stationary device 1 is also a device having a display. Specifically, the stationary device 1 is, for example, a desk clock, a music player, a television, a game console, a smartphone, a tablet PC, or a monitor device. 【0012】 In this embodiment, the stationary device 1 is a desk clock equipped with a rectangular display 5. Therefore, the current time is displayed on the display 5 of the stationary device 1. The current time may be displayed in any format, such as numbers, hour and minute hands, or an image corresponding to that time. The current time may also be displayed by physical hour and minute hands superimposed on the display 5. The shape of the display 5 may be any shape other than a rectangle, such as a quadrilateral (trapezoid, parallelogram, etc.), a polygon, or an ellipse. 【0013】 In this specification, the direction in which the display 5 is provided for a stationary device 1 placed on a mounting surface is referred to as the front, and the direction opposite to the direction in which the display 5 is provided is referred to as the rear. Users can see the content displayed on the display 5 from at least the front. Furthermore, when viewing the display 5 of the stationary device 1 placed on a mounting surface from the front, the upward, downward, left, and right directions are referred to as the upper, downward, left, and right sides of the stationary device 1, respectively. 【0014】 Figure 1 is a schematic perspective view of the stationary device 1. Figure 2 is a cross-sectional view of the stationary device 1 taken from the right along plane Y of Figure 3, which will be described later. Figure 3 is a front view of the stationary device 1. Figure 4 is a six-view drawing of the stationary device 1. As shown in Figures 1 to 4, the stationary device 1 comprises a main body 10 equipped with a display 5 and an operating assembly 30 provided above the main body 10. In particular, the operating assembly 30 (especially the operating unit 31) is positioned so as to overlap the main body 10 when viewed from above. The main body 10 houses a circuit board 20 on which a non-contact sensor 21 and an optical sensor 22 are mounted, a control unit 40 (see Figure 10), and a speaker 6. 【0015】 <Main unit configuration> The main body 10 is a box-shaped member that houses electronic components. In this embodiment, the main body 10 is made of resin. As shown in Figures 1 and 2, in this embodiment, the main body 10 has a circular front surface 10a, a circular rear surface 10b provided on the opposite side of the front surface 10a, and a substantially cylindrical side surface 10c configured to connect the front surface 10a and the rear surface 10b. In particular, in this embodiment, the rear surface 10b is formed as a circle with a smaller diameter than the front surface 10a, and therefore the main body 10 is formed so that its cross-sectional area gradually decreases from front to rear. In other words, the side surface 10c of the main body 10 is formed as a truncated cone with a cross-sectional area that decreases from front to rear. 【0016】 Furthermore, the main body 10 may have any shape as long as one of its surfaces is positioned so as to be visible to the display 5. Therefore, the main body 10 can be any three-dimensional shape, such as a rectangular parallelepiped or a semi-cylindrical shape. 【0017】 As shown in Figure 2, the main body 10 comprises a housing 11, a support member 12 that supports the display 5, an outer frame 13 that extends along the outer circumference of the housing 11 at the front of the housing 11, and a cover 14 that is positioned on the front (display surface) of the display 5. 【0018】 The housing 11 has a substantially cylindrical (or truncated cone) side wall 11a and a disc-shaped rear wall 11b. The side wall 11a is configured such that its axis X (the same as the axis X of the main body 10) extends substantially in the front-rear direction. In particular, in this embodiment, the side wall 11a is configured such that its axis X is slightly inclined downward toward the rear. The rear wall 11b is coupled to the side wall 11a so as to close the rear of the side wall 11a. The outer circumferential surface of the side wall 11a constitutes the side surface 10c of the main body 10, and the rear surface of the rear wall 11b constitutes the rear surface 10b of the main body 10. Electronic components such as a speaker 6, a control unit 40, and a circuit board 20 are housed inside the housing 11. 【0019】 In this embodiment, the support member 12 is a plate-like member formed of an opaque resin and is substantially circular in shape. The support member 12 is positioned in front of the side wall 11a of the housing 11. In particular, in this embodiment, the support member 12 is positioned to close off the front of the side wall 11a of the housing 11. 【0020】 Furthermore, the support member 12 has a groove 12a on its front surface that is recessed to the rear. The display 5 is positioned within this groove 12a. The groove 12a is formed as a rectangle with its longer side extending in the left-right direction. Therefore, in this embodiment, as shown in Figure 3, the display 5 is formed as a rectangle with its longer side extending in the left-right direction when viewed from the front. 【0021】 In addition, the support member 12 has a through hole 12b below the groove 12a that penetrates in the front-to-back direction. In this embodiment, the through hole 12b is located in the center of the support member 12 in the left-to-right direction, and therefore in the center of the front surface 10a of the main body 10 in the left-to-right direction (the same position as the openings 14b2 and 14d2 in Figure 3). Also, in this embodiment, as shown in Figure 3, the through hole 12b is located in the center between the display 5 and the outer frame 13 in the up-to-down direction and is formed in a substantially circular shape (located in the same position as the openings 14b2 and 14d2 in Figure 3 and formed in a similar shape to the openings 14b2 and 14d2). However, the through hole 12b may be formed in any position and shape as long as it is located in a position corresponding to the placement position of the optical sensor 22, which will be described later. 【0022】 The outer perimeter frame 13 is an annular member that extends in front of the housing 11 along the outer circumference of the housing 11. The outer perimeter frame 13 is positioned around the support member 12, enclosing the support member 12. Therefore, the outer perimeter frame 13 extends along the outer circumference of the main body 10 on the front surface 10a of the main body 10. The outer perimeter frame 13 is attached to the front of the side wall 11a of the housing 11 and is connected to the support member 12. Therefore, the outer perimeter frame 13 fixes the support member 12 to the housing 11. 【0023】 Furthermore, in this embodiment, the outer peripheral frame 13 protrudes forward from the front surface of the cover 14 that constitutes the front surface 10a of the main body 10, all the way around. In particular, in this embodiment, as shown in Figure 2, the outer peripheral frame 13 is formed so that its front surface protrudes forward as it moves radially outward. Therefore, the outer peripheral frame 13 constitutes a protruding portion that protrudes forward from the part of the main body 10 (such as the cover 14) around the outer peripheral frame 13, and thus the protruding portion is provided on the periphery of the front surface 10a of the main body 10. 【0024】 In this embodiment, the housing 11, support member 12, and outer frame 13 are configured as separate components. However, some or all of these components may be integrally formed. For example, the support member 12 and the outer frame 13 may be integrally formed, or the side wall 11a of the housing 11 and the outer frame 13 may be integrally formed. 【0025】 The cover 14 is a nearly circular plate-like member, mainly made of transparent or translucent resin. The cover 14 is positioned in front of the support member 12 and the display 5, covering the support member 12 and the display 5. Therefore, the cover 14 extends from the outer circumference of the display 5 to the outside of the display 5 (in a direction perpendicular to the front-to-back direction). Thus, when viewed from the front, the cover 14 is configured to overlap with the display 5 and extend to the outside of the display 5. In this embodiment, the cover 14 is also positioned on the front surface of the support member 12 and the front surface of the display 5, in contact with these front surfaces. Therefore, the front surface of the cover 14 constitutes the front surface 10a of the main body 10. 【0026】 Figure 5 is a schematic diagram showing the configuration of the cover 14. As shown in Figure 5, the cover 14 comprises a transparent or translucent resin circular plate 14a and a plurality of coating layers 14b to 14d. The circular plate 14a may be a polarizing plate that transmits only light in a certain vibration direction, or it may be a plate that does not have a polarizing function. Alternatively, the circular plate 14a may be a light guide plate. 【0027】 As shown in Figure 5, the first coating layer 14b is a layer formed of black paint with low light transmittance and is applied to the rear surface of the circular plate 14a on the display 5 side (rear). The first coating layer 14b also has a first aperture 14b1 in the area corresponding to the display 5 (the area that overlaps with the display 5 when viewed from the front). In addition, the first coating layer 14b has a second aperture 14b2 in the area corresponding to the through hole 12b (light sensor 22) (the area that overlaps with the through hole 12b or the light sensor 22 when viewed from the front). Note that the color of the first coating layer 14b is not limited to black as long as it has low light transmittance. 【0028】 The third coating layer 14d is a layer formed of white paint and is applied behind the first coating layer 14b, overlapping with the first coating layer 14b. Similar to the first coating layer 14b, the third coating layer 14d has a first aperture 14d1 in the area corresponding to the display 5 and a second aperture 14d2 in the area corresponding to the through hole 12b (light sensor 22). By forming the black first coating layer 14b in front of the white third coating layer 14d, the black color appears beautiful when viewed from the front. 【0029】 The second coating layer 14c is a layer formed of paint with a higher transmittance to infrared rays or visible light of certain frequencies than the first coating layer 14b, and is applied to the rear surface of the circular plate 14a. On the other hand, the second coating layer 14c has a lower transmittance to visible light of other frequencies than the aforementioned infrared rays or visible light of certain frequencies, and is formed of paint with a transmittance similar to that of the first coating layer 14b. In particular, the second coating layer 14c is formed in the region corresponding to the through hole 12b (optical sensor 22). Therefore, the second coating layer 14c is formed within the opening 14b2 formed in the first coating layer 14b, or within the opening 14d2 formed in the third coating layer 14d, or both. 【0030】 In Figure 3, the openings 14b2 and 14e2 are depicted as being visible in the area corresponding to the through-hole 12b (optical sensor 22) when viewed from the front. However, because a second coating layer 14c with low transmittance of visible light of certain frequencies is provided, the openings corresponding to the through-hole 12b formed in the first coating layer 14b are difficult to see when viewed from the front by the user, thus preventing the user from unnecessarily recognizing the presence of the optical sensor 22. On the other hand, due to the high transmittance of infrared light or visible light of certain frequencies, the optical sensor 22 can detect light around the stationary device 1. 【0031】 In this embodiment, the first coating layer 14b to the third coating layer 14d are provided behind the circular plate 14a, but they may also be provided in front of the circular plate 14a. Furthermore, if the display 5 itself is provided with a polarizing plate, a plate-shaped member that does not have a polarizing function may be used instead of the circular plate 14a. In addition, at least some of the first coating layer 14b to the third coating layer 14d may be omitted. 【0032】 In this embodiment, the support member 12 and the cover 14 overlap and extend between the display 5 and the outer frame 13. The support member 12 and the cover 14 between the display 5 and the outer frame 13 constitute a surrounding portion 16 that is provided between the display 5, the outer frame 13, and the display, enclosing the display 5. In this embodiment, the support member 12 is configured to overlap with the entire cover 14 when viewed from the front, and therefore the surrounding portion 16 is composed of both the support member 12 and the cover 14. However, the support member 12 may only be provided partially between the display 5 and the outer frame 13, in which case the majority of the surrounding portion 16 will be composed of the cover 14. 【0033】 Furthermore, the cover 14 does not have to be provided. In this case, the display 5 and the support member 12 constitute the front surface of the main body 10. Also in this case, the surrounding portion 16 will consist only of the support member 12. 【0034】 <Configuration of the circuit board and sensor> The substrate 20 is a component housed within the main body 10 and on which various electronic components are mounted. In this embodiment, as shown in Figure 2, the substrate 20 is positioned in an area close to the front surface 10a of the main body 10, i.e., at the front of the main body 10. In this embodiment, the substrate 20 is positioned immediately behind the front surface 10a of the main body 10. Specifically, the substrate 20 is positioned immediately behind the support member 12 and is attached to the support member 12. As shown in Figure 2, in this embodiment, the substrate 20 is positioned to extend in a direction perpendicular to the front-rear direction, i.e., to extend parallel to the front surface 10a of the main body 10. As shown in Figure 2, a non-contact sensor 21 and an optical sensor 22 are mounted on the substrate 20. 【0035】 The non-contact sensor 21 is a sensor that detects objects around the stationary device 1, particularly in front of it, without contact. For example, the non-contact sensor 21 is a sensor that detects the presence or absence of an object in front of the stationary device 1 and, if an object is present, its position. In this embodiment, the non-contact sensor 21 is a millimeter-wave sensor that emits a millimeter-wave signal and receives a signal reflected from a surrounding object, and detects the position of the surrounding object based on the emitted signal and the received signal. The non-contact sensor 21 detects that the surrounding object has moved when the position of the surrounding object changes over time. Note that the detection of the position or movement of an object based on the detection results of the non-contact sensor 21 may be performed not by the non-contact sensor 21 itself, but by the control unit 40 that receives the output signal of the non-contact sensor 21. 【0036】 The non-contact sensor 21 can be any sensor that can detect an object without contact. Therefore, the non-contact sensor 21 is not limited to a millimeter-wave sensor, but may be, for example, an infrared sensor, an ultrasonic sensor, a Doppler sensor, or a temperature sensor. The visible light sensor is a sensor that has a light emitter and detects the position of an object based on the reflected light waves emitted from the light emitter. The temperature sensor is a sensor that detects the temperature of objects around the stationary device 1, and detects, for example, that surrounding objects have moved when a high-temperature area moves. 【0037】 Figure 6 is an enlarged cross-sectional view of the upper front part of the main body 10, in the same cross-section as in Figure 2. As shown in Figure 6, the non-contact sensor 21 is positioned on the front surface of the substrate 20. Therefore, the non-contact sensor 21 is positioned at the front of the main body 10. Furthermore, the non-contact sensor 21 is positioned above the display 5 and below the outer frame 13. Therefore, the non-contact sensor 21 is positioned such that the support member 12 and cover 14 are located in front of it. That is, when viewed from the front, the non-contact sensor 21 is positioned so as to overlap with the support member 12 and cover 14, and in particular so as to overlap with the surrounding portion 16. The non-contact sensor 21 transmits and receives millimeter waves by passing through the support member 12 and cover 14 positioned in front of it. The non-contact sensor 21 then detects the movement of an object located within a predetermined angular range centered on the direction toward the front from the non-contact sensor 21. 【0038】 Furthermore, Figure 3 shows the position where the non-contact sensor 21 is located when viewed from the front, indicated by a dashed line. As can be seen from Figure 3, the non-contact sensor 21 is located in the center (not necessarily exactly in the center, but including the vicinity of the center) of the front surface 10a of the main body 10 when viewed from the front. In this embodiment, the non-contact sensor 21 is positioned to intersect with a surface Y that extends vertically through the axis X of the main body 10. 【0039】 The light sensor 22 is a sensor that detects the light surrounding the stationary device 1. In particular, the light sensor 22 is an illuminance sensor that detects the illuminance in front of the stationary device 1. However, the light sensor 22 can be any sensor that can detect the intensity and / or color of the light surrounding the stationary device 1, or the intensity and / or color of the light in a specific area around the stationary device 1. Furthermore, the light sensor 22 may be able to continuously detect the light intensity, or it may be able to detect it in two or more stages. 【0040】 Figure 7 is an enlarged cross-sectional view of the lower front part of the main body 10, in the same cross-section as in Figure 2. As shown in Figure 7, the optical sensor 22 is located on the front surface of the substrate 20. Therefore, the optical sensor 22 is located at the front of the main body 10. Furthermore, the optical sensor 22 is located below the display 5 and above the outer frame 13. Therefore, the optical sensor 22 is positioned such that the cover 14 is located in front of it. That is, when viewed from the front, the optical sensor 22 is positioned so as to overlap with the cover 14, and in particular with the surrounding portion 16. In addition, the optical sensor 22 is located below the non-contact sensor 21. 【0041】 Furthermore, Figure 3 shows the position where the light sensor 22 is installed when viewed from the front, indicated by a dashed line. As can be seen from Figure 3, the light sensor 22 is positioned in the center (not necessarily exactly in the center, but including the vicinity of the center) in the left-right direction of the front surface 10a of the main body 10 when viewed from the front. In this embodiment, the light sensor 22 is positioned to intersect with a surface Y that extends vertically through the axis X of the main body 10. In particular, in this embodiment, the light sensor 22 is positioned to overlap with the second opening 14b2 of the first coating layer 14b and the second opening 14d2 of the third coating layer 14d when viewed from the front. 【0042】 In addition, the light sensor 22 is positioned so as to overlap the through-hole 12b of the support member 12 when viewed from the front. As shown in Figure 5, in this embodiment, a light guide lens 23 is provided in front of the light sensor 22 and within the through-hole 12b. The front end of the light guide lens 23 faces the cover 14, and the rear end faces the light sensor 22. At its front end, the light guide lens 23 focuses light over a wide angular range in front of the stationary device 1 and directs the focused light towards the light guide lens 23. Therefore, the front end of the light guide lens 23 functions as a light-gathering section for the light sensor 22. If the light guide lens 23 is not provided, the front end of the light sensor 22 may function as a light-gathering section for the light sensor 22. 【0043】 Furthermore, in this embodiment, the light-gathering portion (the front surface of the light guide lens 23) and the main body 10 are configured such that a portion of the main body 10 is positioned on a line segment connecting the light-gathering portion and any point on the operating section 31 of the operating assembly 30, which will be described later. Figure 2 shows the line segment Zf that extends furthest forward and the line segment Zr that extends furthest backward among these line segments. Both of these line segments Zf and Zr intersect with components that make up the main body 10. By positioning a portion of the main body 10 on the line segment connecting the light-gathering portion and the operating section 31, the influence of light emission from the operating section 31 on the light sensor 22 can be suppressed. 【0044】 In this embodiment, the non-contact sensor 21 and the optical sensor 22 are mounted on the same substrate 20. However, the non-contact sensor 21 and the optical sensor 22 may be mounted on separate substrates. Alternatively, the non-contact sensor 21 and the optical sensor 22 may not be mounted on a substrate but be connected to the substrate via wiring. 【0045】 <Configuration of the operating assembly> Figure 8 is an enlarged cross-sectional view of the operation assembly 30, showing the same cross-section as in Figure 2. Figure 9 is an exploded perspective view of the operation assembly 30. The operation assembly 30 is for the user to operate various functions of the stationary device 1. Therefore, when the user performs operations such as pushing, pulling, tilting, touching, or rotating on the operation section 31 of the operation assembly 30, the stationary device 1 operates in response to these operations. Specifically, the display on the display 5 changes, sound is output from the speaker 6, and the illumination pattern of the operation assembly 30 changes in response to these operations. The operation assembly 30 is also configured so that the operation section 31 operated by the user can emit light. 【0046】 As shown in Figures 8 and 9, the operating assembly 30 comprises an operating section 31, a base member 32, an annular member 33, an elastic member 34, and an operating section substrate 35. The base member 32 is fixed to the upper part of the housing 11, and the operating section 31 is mounted so as to be rotatable and slidable in the direction of the base member 32's axis Z. A light-emitting element 36 is provided on the operating section substrate 35, and the operating assembly 30 is configured such that when the light-emitting element 36 emits light, the operating section 31 appears to light up. 【0047】 The operating unit 31 is positioned above the main body 10, and as shown in the plan view of Figure 4, it is positioned so as to overlap the main body 10 when viewed from above. The operating unit 31 is also positioned behind the light sensor 22, and in particular the light-gathering unit for the light sensor 22. The operating unit 31 includes an internal member 31a, an outer peripheral member 31b provided above and to the side of the internal member 31a so as to surround the internal member 31a, a fixing member 31c attached below the internal member 31a, and a magnet 31d positioned below the center of the internal member 31a. 【0048】 The encapsulating member 31a is formed of a light-diffusing material. The encapsulating member 31a is formed of a resin containing a dispersed diffusing agent. When the light-emitting body 36 emits light and that light is incident on the encapsulating member 31a, it diffuses the light around it. As shown in Figure 8, the encapsulating member 31a is formed in a cylindrical shape with the center of its upper surface bulging upwards. The outer peripheral member 31b is arranged to surround the encapsulating member 31a and is formed of a hard, transparent resin that can be grasped by the user. The fixing member 31c is formed of a hard, transparent resin in a circular plate shape. In this embodiment, the fixing member 31c has an inwardly recessed notch 31e at one location on its outer circumference. The fixing member 31c is also fixed below the encapsulating member 31a by fasteners 31f such as screws. In particular, in this embodiment, the fixing member 31c is fixed to the inner member 31a such that a groove 31g recessed radially inward is formed on the side surface of the operating part 31 by the inner member 31a and the fixing member 31c. The magnet 31d is positioned between the central lower surface of the inner member 31a and the central upper surface of the fixing member 31c. Specifically, the magnet 31d is positioned so that its magnetic field lines extend in a direction perpendicular to the vertical direction (the axial direction of the operating part 31). 【0049】 The base member 32 has a cylindrical portion 32a, a flange 32b projecting inward from the cylindrical portion 32a, and leg portions 32c projecting inward and downward from the cylindrical portion 32a. The cylindrical portion 32a is fixed to the upper part of the side wall 11a of the housing 11 and projects substantially upward from the upper surface of the side wall 11a (i.e., the upper side surface 10c of the main body 10). In this embodiment, the cylindrical portion 32a is formed such that the rear side is higher than the front side in the axial Z direction of the base member 32. 【0050】 Furthermore, the flange 32b protrudes inward near the upper end of the cylindrical portion 32a, and the flange 32b fits into a groove 31g formed in the operating portion 31. As a result, the operating portion 31 is connected to the base member 32 so that it can rotate around the axis of the base member 32. Also, since the vertical thickness of the flange 32b is sufficiently smaller than the vertical width of the groove 31g, the operating portion 31 can slide vertically (more precisely, in the axial direction of the base member 32) relative to the base member 32. 【0051】 Two leg portions 32c are provided on the cylindrical portion 32a and are positioned symmetrically with respect to the axis Z of the base member 32. The leg portions 32c protrude inward from the inner surface of the cylindrical portion 32a. In addition, the upper end of the leg portion 32c is located below the upper end of the cylindrical portion 32a in the direction of the axis Z, and the lower end of the leg portion 32c is configured to protrude downward from the lower end of the cylindrical portion 32a in the direction of the axis Z. 【0052】 The annular member 33 is positioned inside the cylindrical portion 32a and below the operating portion 31. In this embodiment, the annular member 33 has two inwardly recessed notches 33a on its outer circumference. These two notches 33a are positioned symmetrically with respect to the axis Z. The annular member 33 is positioned within the base member 32 such that the leg portion 32c is located within its notches 33a. The annular member 33 is also positioned so that it cannot rotate around the axis Z of the base member 32. Therefore, when the operating portion 31 rotates, the lower surface of the fixing member 31c of the operating portion 31 slides against the upper surface of the annular member 33. In addition, the annular member 33 is biased upward by the elastic member 34. Therefore, the annular member 33 biases the operating portion 31 upward, causing the upper surface of the fixing member 31c of the operating portion 31 to contact the lower surface of the flange 32b, as shown in Figure 8. 【0053】 The elastic member 34 biases the annular member 33 upward (in the axial direction of the cylindrical portion 32a and away from the operating unit base plate 35). In particular, the elastic member 34 is provided between the annular member 33 and the operating unit base plate 35 and biases the annular member 33 away from the operating unit base plate 35. Specifically, as shown in Figure 9, the elastic member 34 has a plurality of protrusions 34a that project upward in the axial Z direction of the base member 32. In this embodiment, the elastic member 34 is provided with three protrusions 34a, one of which is provided on the front side of the elastic member 34 and the remaining two protrusions 34a are provided on the rear side of the elastic member 34. These three protrusions 34a bias the annular member 33 away from the operating unit base plate 35. As a result, when the operating unit 31 is not pressed by the user, the upper surface of the fixing member 31c contacts the lower surface of the flange 32b of the base member 32. 【0054】 Furthermore, a plate-shaped conductor 34b is provided on the lower surface of the projection 34a. In this embodiment, the conductor 34b is provided on the lower surface of one projection located on the front side of the elastic member 34. When the operating part 31 is not pressed by the user, the lower surface of the projection 34a is separated from the upper surface of the operating part substrate 35. 【0055】 The elastic member 34 biases the operating part 31 with a force such that the operating part 31 moves downward when the operating part 31 is pushed downward by the user. Therefore, when the operating part 31 is pushed downward by the user, the operating part 31 moves downward, the elastic member 34 deforms (in particular the projection 34a deforms), and as a result, the conductor 34b of the operating part 31 provided on the lower surface of the projection 34a comes into contact with the contact 35b (described later) of the operating part substrate 35. 【0056】 Furthermore, in this embodiment, the elastic member 34 has two inwardly recessed notches 34c on its outer circumference. These two notches 34c are positioned symmetrically with respect to the axis Z. The annular member 33 is positioned within the base member 32 such that its leg portion 32c is located within its notches 34c. In addition, the elastic member 34 is fixed to the operating unit substrate 35 and therefore cannot rotate around the axis Z of the base member 32. 【0057】 The control panel circuit board 35 is housed within the main body 10 and is a component on which various electronic components are mounted. In this embodiment, the control panel circuit board 35 is positioned below the elastic member 34 and fixed to the housing 11 of the main body 10. The control panel circuit board 35 is positioned to extend in a direction perpendicular to the axis of the control panel 31. As shown in Figure 8, the control panel circuit board 35 is also provided with a magnetic sensor 35a, a contact 35b, and a light-emitting element 36. 【0058】 Furthermore, in this embodiment, the operating section substrate 35 has two inwardly recessed notches 35c on its outer circumference. These two notches 35c are positioned symmetrically with respect to the axis Z. The operating section substrate 35 is placed within the base member 32 such that the leg portions 32c are located within the notches 35c. 【0059】 The magnetic sensor 35a is a sensor that detects the direction and magnitude of a magnetic field. The magnetic sensor 35a is positioned on the upper surface of the operating unit substrate 35, on the axis of the operating unit 31. Therefore, the magnetic sensor 35a is positioned in close proximity to the magnet 31d of the operating unit 31 and detects the direction of the magnetic field lines generated by the magnet 31d. When the operating unit 31 rotates, the direction of the magnetic field lines generated by the magnet 31d changes. By detecting the direction of these magnetic field lines, the magnetic sensor 35a can detect the rotation of the operating unit 31 and its angle. In particular, in this embodiment, by utilizing the magnet 31d and the magnetic sensor 35a, the rotation of the operating unit 31 and its angle can be detected while allowing the operating unit 31 to move in its axial direction. 【0060】 The contact 35b is formed of a metallic conductor. The contact 35b is positioned below the conductor 34b of the elastic member 34 and contacts the conductor 34b when the front projection 34a of the elastic member 34 deforms. The contact 35b is electrically connected to the control unit 40 and is configured such that the electrical signal sent to the control unit 40 differs depending on whether the conductor 34b and the contact 35b are in contact or not. As described above, when the operating unit 31 is not pressed by the user, the conductor 34b and the contact 35b are separated, and when the operating unit 31 is pressed by the user, the conductor 34b and the contact 35b are in contact. Therefore, it is possible to determine whether or not the operating unit 31 is being pressed by the user based on the conductor 34b and the contact 35b. 【0061】 The light-emitting element 36 is a device that emits light according to an electrical signal from the control unit. The light-emitting element 36 is, for example, an LED (Light Emitting Diode). The light-emitting element 36 is positioned below the operating unit 31 and on the upper surface of the operating unit substrate 35. In particular, the light-emitting element 36 is positioned so that it overlaps with the operating unit 31 when viewed from above. The light emitted from the light-emitting element 36, positioned in this manner, enters the operating unit 31 through the central opening of the annular member 33 and is diffused in the enclosed member 31a. As a result, when light is emitted from the light-emitting element 36, the entire operating unit 31 appears to glow. 【0062】 In this embodiment, the operating assembly 30 is formed such that the rear side of the cylindrical portion 32a is higher than the front side in the Z-axis direction of the base member 32. Furthermore, a conductor 34b is provided only on the front projection 34a of the elastic member 34. Therefore, when the user presses the operating unit 31, the operating unit 31 moves downward with the rear upper end of the cylindrical portion 32a as the pivot point, causing the front projection 34a of the elastic member 34 to deform and the conductor 34b to come into contact with the contact 35b. Here, for example, if a conductor were provided on all the projections and the cylindrical portion was formed at the same height overall in the Z-axis direction, when the user presses the operating unit, depending on how the user presses, the front side of the operating unit may lower first, followed by the rear side of the operating unit. In this case, the conductor of the front projection would come into contact with the contact, and then the conductor of the front projection would move away from the contact, and the conductor of the rear projection would come into contact with the contact, resulting in a double sensation when the user presses the operating unit, and potentially causing two unintended inputs. In contrast, in this embodiment, the configuration described above prevents the user from experiencing a double press sensation or unintentionally performing two inputs. 【0063】 Furthermore, in this embodiment, the annular member 33, the elastic member 34, and the operating part substrate 35 are provided with notches 33a, 34c, and 35c, respectively, so that these members do not interfere with the leg portion 32c. Also, the fixing member 31c is positioned above the leg portion 32c in the axial Z direction, so it does not interfere with the leg portion 32c. However, the fixing member 31c has only one notch 31e. This makes it possible to easily assemble the fixing member 31c to the internal member 31a by first fitting the portion without the notch 31e above one leg portion 32c, and then moving the portion with the notch 31e upward along the other leg portion 32c. Furthermore, since the fixing member 31c has only one notch 31e, the feel during rotational operation by the user is improved compared to when multiple notches 31e are provided. 【0064】 In this embodiment, the operating assembly 30 is configured so that the user can push in and rotate the operating part 31. However, the operating assembly 30 may be configured so that the user can only push in or rotate the operating part 31, or the operating assembly 30 may be configured so that it cannot be operated by the user. However, in any case, the operating assembly 30 must be configured to emit light. Furthermore, the operating assembly 30 may be formed in a form different from the above-described form, as long as it can emit light. Therefore, the operating assembly 30 may not have a light-emitting body 36, and the operating part 31 may be coated with a light-emitting paint. Also, in this embodiment, the entire operating part 31 emits light, but only a part of it may emit light. 【0065】 Furthermore, in this embodiment, the operating assembly 30 is formed to be inserted into the upper surface of the main body 10. However, the operating assembly 30 may be formed separately from the main body 10 and placed on the upper surface of the main body 10 (i.e., on the side surface 10c such that the operating assembly 30 is positioned on top of the main body 10 when the main body 10 is viewed from above). 【0066】 Furthermore, in this embodiment, a conductor 34b is provided on the underside of only one of the front protrusions 34a. However, the conductor 34b may be provided on any of the protrusions 34a, including the two rear protrusions 34a, and contacts 35b may be provided at corresponding positions on the operating section substrate 35. In addition, two or more protrusions 34a may be provided on the elastic member 34. 【0067】 <Configuration of electronic components> Next, the configuration of the electronic components in the stationary device 1 will be described with reference to Figure 10. Figure 10 is a block diagram schematically showing the configuration of the electronic components in the stationary device 1. As shown in Figure 10, the stationary device 1 includes a display 5, a speaker 6, a light-emitting element 36, a non-contact sensor 21, an optical sensor 22, a magnetic sensor 35a, a contact 35b, and a control unit 40. In addition, the stationary device 1 further includes a battery (not shown) that supplies power to the display 5 and the control unit 40, etc. In this embodiment, the display 5, speaker 6, light-emitting element 36, non-contact sensor 21, optical sensor 22, magnetic sensor 35a, contact 35b, and control unit 40 are housed in the main body 10, but some of them do not have to be housed in the main body 10, and may be housed, for example, in the operating assembly 30. 【0068】 The display 5 is electrically connected to the control unit 40 and displays an image according to the image signal from the control unit 40. The display 5 displays an image according to the computer program executed by the control unit 40. The display 5 is, for example, a liquid crystal display, an electroluminescent (EL) display, or a plasma display. 【0069】 Speaker 6 is electrically connected to the control unit 40 and outputs sound according to the audio signal from the control unit 40. Speaker 6 also outputs sound according to the computer program being executed by the control unit 40. 【0070】 The light-emitting element 36 is electrically connected to the control unit 40 and emits light in response to a control signal or power supply from the control unit 40. The light-emitting element 36 may be configured to emit light in a single color or in multiple different colors. The light-emitting element 36 may also be configured to allow its light emission intensity to be changed in steps or continuously. 【0071】 The non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contact 35b are electrically connected to the control unit 40. The output signals from the non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contact 35b are input to the control unit 40. Specifically, the non-contact sensor 21 inputs an output signal indicating the presence and position of an object in front of the stationary device 1. The optical sensor 22 inputs a signal indicating the illuminance in front of the stationary device 1. Furthermore, the magnetic sensor 35a inputs a signal indicating the direction and magnitude of the magnetic field. In addition, the contact 35b inputs a signal indicating whether or not the conductor 34b has made contact with the contact 35b. 【0072】 <Configuration and operation of the control unit> The control unit 40 transmits control signals to the display 5, speaker 6, and light-emitting element 36, etc., according to the running computer program, based on signals received from the non-contact sensor 21, optical sensor 22, magnetic sensor 35a, and contact 35b. The control unit 40 includes a communication interface 41, a memory 42, and a processor 43. The communication interface 41, memory 42, and processor 43 may be separate circuits or may be configured as a single integrated circuit. 【0073】 The communication interface 41 is a circuit for connecting the control unit 40 to other electronic components in the main unit 10. The memory 42 is a storage medium for storing data. The memory 42 may be, for example, a volatile semiconductor memory or a non-volatile semiconductor memory. In addition, the memory 42 may have removable media such as a memory card or optical disc. The memory 42 stores computer programs executed by the processor 43. The memory 42 also stores various data used by the running program, such as output signals from the non-contact sensor 21. 【0074】 The processor 43 has one or more CPUs (Central Processing Units) and their peripheral circuits. The processor 43 may further have other arithmetic circuits such as a logic unit or a numerical unit. The processor 43 executes various processes based on a computer program stored in the memory 42. For example, the processor 43 executes control processing for the display 5, speaker 6 and light-emitting element 36, and generates and outputs control signals to be output to the display 5, speaker 6 and light-emitting element 36. 【0075】 Furthermore, the processor 43 controls the functions of the stationary device 1 based on the output signals from the non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contact 35b. 【0076】 In this embodiment, the processor 43 controls several functions of the stationary device 1 based on the output signal of the non-contact sensor 21. For example, the processor 43 controls the illumination of the operating assembly 30 (i.e., illumination of the light-emitting element 36), the brightness of the display 5 screen, the content displayed on the display 5, and the audio output from the speaker 6, based on the output signal of the non-contact sensor 21. The processor 43 may control only one function of the stationary device 1 based on the output signal of the non-contact sensor 21. Furthermore, the processor 43 may control only some of the illumination of the operating assembly 30, the brightness of the display 5 screen, the content displayed on the display 5, and the audio output from the speaker 6, or it may control all of these functions. 【0077】 Specifically, for example, the processor 43 may change the light emission mode of the operating assembly 30 when the output signal of the non-contact sensor 21 indicates that an object in front of the stationary device 1 has moved from within a predetermined area to outside a predetermined area. The processor 43 may also change the brightness of the display 5 screen based on whether or not the output signal of the non-contact sensor 21 has detected a large movement of an object. Furthermore, for example, if sound such as an alarm is being output from the speaker 6, and the output signal of the non-contact sensor 21 indicates that an object in front of the stationary device 1 is moving, the processor 43 may consider that a person in front of the stationary device 1 has woken up and therefore stop the sound output from the speaker 6. Also, for example, if sound such as an alarm is being output from the speaker 6, and the output signal of the non-contact sensor 21 continues to indicate that an object in front of the stationary device 1 is not moving at all, the processor 43 may consider that there is no person in front of the stationary device 1 and therefore stop the sound output. 【0078】 Furthermore, the processor 43 controls the brightness of the display 5 screen based on the output signal of the light sensor 22. In this embodiment, the processor 43 brightens the display 5 screen when the output signal of the light sensor 22 indicates that it is bright around the stationary device 1, for example, when the illuminance detected by the light sensor 22 is high. On the other hand, the processor 43 dims the display 5 screen when the output signal of the light sensor 22 indicates that it is dark around the stationary device 1, for example, when the illuminance detected by the light sensor 22 is low. The output signal from the light sensor 22 may be the illuminance itself, or it may be binary information indicating whether or not it exceeds a specific reference value. 【0079】 Furthermore, if the processor 43 controls the brightness of the display 5 screen based on the output signal of the light sensor 22, it does not need to control the area around the stationary device 1 to correspond linearly to the brightness. Therefore, for example, if the output signal of the light sensor 22 indicates that the area around the stationary device 1 has suddenly become dark, the processor 43 may gradually dim the screen of the display 5, or dim the screen of the display 5 after a certain period of time has elapsed since the area around the stationary device 1 suddenly became dark. In addition, in this embodiment, the processor 43 controls only the brightness of the display 5 screen based on the output signal of the light sensor 22, but it may also control other functions of the display 5 screen based on the output signal of the light sensor 22. For example, the processor 43 may change the brightness at which the operation assembly 30 is illuminated based on the output signal of the light sensor 22. 【0080】 Furthermore, the processor 43 controls several functions of the stationary device 1 based on the output signal from the magnetic sensor 35a and the output signal from the contact 35b. For example, if the output signal from the magnetic sensor 35a and the output signal from the contact 35b indicate that the operation unit 31 is being operated in a predetermined manner, the processor 43 sets the time at which an alarm or other sound should be output from the speaker 6 and stores it in the memory 42. Also, for example, if the output signal from the magnetic sensor 35a and the output signal from the contact 35b indicate that the operation unit 31 is being operated in another predetermined manner, the processor 43 sets the color at which the operation assembly 30 should be illuminated and stores it in the memory 42. 【0081】 The following describes the specific control when the light emission mode of the operating assembly 30 is changed when the output signal of the non-contact sensor 21 indicates that an object in front of the stationary device 1 has moved from within a predetermined area to outside that area, with reference to Figure 11. 【0082】 First, we will describe a method for determining whether an object in front of the stationary device 1 has moved from within a predetermined area to outside of a predetermined area, for example, whether a user has moved from within a predetermined bed area to outside of a predetermined bed area, based on the output signal of the non-contact sensor 21, which is a millimeter-wave sensor. Figure 11 is a schematic diagram showing the detection range of the non-contact sensor 21 when the stationary device 1 is installed next to the bed B where the user sleeps. In the example shown in Figure 11, the stationary device 1 is installed next to the bed B so that the front surface 10a of the stationary device 1 faces the bed B. As shown in Figure 11, the detection range of the non-contact sensor 21 extends over a certain angular range (the area shown in gray in the figure). In addition, the non-contact sensor 21 can detect objects up to a distance that is well beyond the size of a typical bed B (the area shown in gray in the figure). Therefore, the non-contact sensor 21 can detect the movement of objects up to a distance beyond the bed B within this angular range. 【0083】 Furthermore, in this embodiment, the processor 43 pre-sets the area where the bed B is located, i.e., the area where the user lies, as a predetermined bed area within the detection range of the non-contact sensor 21. The processor 43 sets the bed area, for example, based on the user's operation of the operation unit 31 of the operation assembly 30. Alternatively, the processor 43 may set the area where movement of an object is detected (for example, an area where movement is detected by the user deliberately moving around on the bed) as the bed area when the stationary device 1 is set to bed area detection mode. 【0084】 Here, as shown in Figure 11, consider the case where the user moves from inside bed B to outside bed B within the detection range of the non-contact sensor 21, that is, when the user moves in the direction indicated by the white arrow in Figure 11. In such a case, the output signal of the non-contact sensor 21 will change from indicating that a large object movement, such as the user's movement, is within the preset bed area to indicating that it is outside the bed area. Therefore, the processor 43 determines that the output signal of the non-contact sensor 21 indicates that an object in front of the stationary device 1 has moved from within a predetermined area to outside the predetermined area, when the output signal of the non-contact sensor 21 indicates that an object has moved from within the bed area to outside the bed area. 【0085】 On the other hand, as shown in Figure 11, consider the case where the user moves from inside bed B to outside bed B outside the detection range of the non-contact sensor 21, that is, when the user moves in the direction indicated by the shaded arrow in Figure 11. In such a case, the output signal of the non-contact sensor 21 indicates that there is no movement of objects outside the bed area. On the other hand, when the user is on bed B, the output signal of the non-contact sensor 21 indicates that there is some small movement, such as movement due to the user breathing. However, when the user moves in the direction indicated by the shaded arrow, the output signal of the non-contact sensor 21 indicates that there is no movement at all after the user moves. Therefore, in this embodiment, the processor 43 determines from the output signal of the non-contact sensor 21 that, after a large movement occurred within the bed area, no movement of objects within the bed area occurred for a predetermined reference time, indicating that the object in front of the stationary device 1 has moved from inside a predetermined area to outside a predetermined area. 【0086】 In this embodiment, the processor 43 causes the operating assembly 30 to emit light in a predetermined color for a predetermined period of time if the output signal from the non-contact sensor 21 indicates that an object in front of the stationary device 1 has moved from within a predetermined area to outside that area. As a result, the user can confirm that the stationary device 1 has recognized that they have left the bed B. 【0087】 Furthermore, if the output signal from the non-contact sensor 21 indicates that an object in front of the stationary device 1 has moved from within a predetermined area to outside that area, the processor 43 may change the illumination mode of the operation assembly 30 to a mode different from the illumination mode in such a case, and the operation assembly 30 may illuminate in any manner. For example, in such a case, the processor 43 may make the operation assembly 30 blink, or make the operation assembly 30 illuminate in a way that gradually changes color. Also, if the operation assembly 30 had been illuminating up to that point, the processor 43 may stop illuminating it. 【0088】 Next, the control of the brightness of the display 5 screen based on the output signals of the non-contact sensor 21 and the light sensor 22 will be described. The processor 43 brightens the screen of the display 5 as the illuminance detected by the light sensor 22 increases. This makes the screen of the display 5 easier for the user to see, regardless of the ambient light around the stationary device 1. 【0089】 Furthermore, the processor 43 changes the brightness of the display 5 screen depending on whether the output signal of the non-contact sensor 21 indicates that there is movement of an object within the bed area. When the output signal of the non-contact sensor 21 indicates that there is significant movement of an object, the screen of the display 5 is made brighter than when the output signal of the non-contact sensor 21 indicates that there is no significant movement of an object. In this way, when the user is active in front of the stationary device 1, the screen of the display 5 becomes brighter, improving the user's visibility. On the other hand, when the user in front of the stationary device 1 is sleeping or there is no user in front of the stationary device 1, the display 5 becomes dim, thus preventing the screen of the display 5 from becoming too bright during the user's sleep, which could disturb their sleep, or unnecessarily increasing power consumption. 【0090】 Furthermore, when the illuminance detected by the light sensor 22 is above a predetermined level, the brightness of the display 5 screen does not need to be changed depending on whether or not there is a large movement of an object. This prevents situations where, when the area around the stationary device 1 is bright, the moving hand covers the light sensor 22, causing the screen to dim and making it difficult for the user to identify the displayed content. 【0091】 In this embodiment, the brightness of the display 5 screen is changed depending on whether or not a large movement of an object is detected. However, for example, if no large movement of an object has been detected for a certain period of time, the display 5 screen will be brightened when a large movement of an object is detected. However, if the period during which no large movement of an object was detected is shorter than the aforementioned certain period of time, the display 5 screen does not need to be brightened even if a large movement of an object is detected. This prevents the brightness of the display 5 from being changed too frequently depending on whether or not a large movement of an object is detected. 【0092】 <Effects and variations> The effects of the stationary device 1 configured as described above will now be explained. In the stationary device 1 according to the above embodiment, the operation unit 31 provided above the stationary device 1 is configured to emit light. Furthermore, in the stationary device 1 according to the above embodiment, the optical sensor 22 is provided below the non-contact sensor 21. As a result, the optical sensor 22 is positioned further away from the operation unit 31 than the non-contact sensor 21, and thus the detection result of the optical sensor 22 is suppressed from being affected by the light emitted from the operation unit 31. Therefore, with the stationary device 1 according to the above embodiment, the optical sensor 22 can perform its function more easily. In other words, with the stationary device 1 according to the above embodiment, the operation unit 31 can emit light without considering the effect on the optical sensor 22. 【0093】 Furthermore, since the non-contact sensor 21 is positioned above the optical sensor 22, the non-contact sensor 21 is positioned relatively high on the stationary device 1. It is conceivable that some kind of obstacle may be placed in front of the stationary device 1, but by positioning the non-contact sensor 21 at a high position, the detection by the non-contact sensor 21 is less likely to be hindered by such obstacles, making it easier to accurately detect objects in front of the stationary device 1, especially the movements of the user. Therefore, according to the stationary device 1 of the above embodiment, the non-contact sensor 21 is able to perform its function more easily. 【0094】 In particular, in the above embodiment, the optical sensor 22 is positioned below the display 5, and the non-contact sensor 21 is positioned above the display 5. As a result, the optical sensor 22 is positioned further away from the operation unit 31, and the influence of light emission from the operation unit 31 on the detection results of the optical sensor 22 is further suppressed. In addition, the non-contact sensor 21 is positioned higher, and thus the influence of obstacles can be further reduced. 【0095】 In particular, in the above embodiment, the light sensor 22 is positioned in the surrounding area 16 between the outer frame 13 and the display 5, so as to overlap with the cover 14 when viewed from the front. As a result, the light sensor 22 is positioned relatively close to the display 5. As described above, since the brightness of the display 5 is changed based on the output signal of the light sensor 22, the brightness of the display 5 can be changed more appropriately according to the illuminance around the display 5. Furthermore, the area of ​​the surrounding area 16 between the outer frame 13 and the display 5 is a necessary area even without providing these sensors 21 and 22, so there is no need to separately provide a place for these sensors 21 and 22 in the stationary device 1, and the stationary device 1 can be made compact. 【0096】 Furthermore, in the stationary device 1 according to the above embodiment, both the non-contact sensor 21 and the optical sensor 22 are positioned in the center of the front surface 10a of the main body 10 in the left-right direction (lateral direction), intersecting with surface Y. By positioning the non-contact sensor 21 and the optical sensor 22 in the center in the left-right direction in this way, biased detection of the movement of objects in front of the stationary device 1 and the brightness in front of the stationary device 1 is suppressed. 【0097】 In addition, in the stationary device 1 according to the above embodiment, the main body 10 is configured such that a part of it is located on a line segment connecting an arbitrary point on the operation unit 31 and the light-gathering unit for the light sensor 22. Therefore, even when the operation unit 31 emits light, the light is suppressed from directly entering the light-gathering unit, and thus the detection result of the light sensor 22 is further suppressed from being affected by the light emitted from the operation unit 31. In addition, in the stationary device 1 according to the above embodiment, the outer frame 13 forms a protruding portion that projects forward from the front surface of the cover 14, and the operation unit 31 is positioned behind the light sensor 22. As a result, when the operation unit 31 emits light, the light is further less likely to enter the light-gathering unit for the light sensor 22, and the detection result of the light sensor 22 is further suppressed from being affected by the light emitted from the operation unit 31. 【0098】 The outer frame 13 may be configured to protrude forward at the top of the main body 10 (i.e., above the optical sensor 22, which will be described later), but not to protrude forward in other areas (such as the bottom of the main body 10). 【0099】 Alternatively, the outer perimeter frame 13 may be configured to protrude radially outward from the side wall 11a of the housing 11 that constitutes the side surface 10c of the main body 10. In this case, at the upper part of the main body 10, the outer perimeter frame 13 constitutes a protruding portion that protrudes radially outward from the part of the main body 10 around the outer perimeter frame 13 (such as the side wall 11a of the housing 11). Furthermore, the outer perimeter frame 13 may be configured to protrude upward (i.e., radially outward) at the upper part of the main body 10 (i.e., above the light sensor 22), but not to protrude radially outward in other areas (such as the lower part of the main body 10). The direction of protrusion of the outer perimeter frame 13 is not limited to forward and upward, but may be any direction as long as it suppresses the detection result of the light sensor 22 from being affected by the light emission at the operation unit 31. 【0100】 Furthermore, in the stationary device 1 according to the above embodiment, the illumination of the operation unit 31 is controlled based on the output signal of the non-contact sensor 21. In particular, in the above embodiment, when the non-contact sensor 21 determines, based on the output signal, that an object has moved from within a predetermined bed area to outside the bed area, the illumination pattern of the operation unit 31 is changed. As a result, when the movement of an object is detected by the non-contact sensor 21, the illumination pattern of the operation unit 31, which is positioned in a conspicuous location on the top of the stationary device 1, changes, so that the user can easily visually confirm that the movement has been detected correctly. 【0101】 While preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to these embodiments, and various modifications and changes can be made within the scope of the claims.
