DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, the embodiments will be described in detail with reference to the drawings. In the following description, like components are designated by like reference numerals.

[0011] <Overall structure> A stationary device 1 according to one embodiment will be described with reference to Figs. 1 to 4. The stationary device 1 is a device that is placed on an installation surface such as a table, floor, or shelf. The stationary device 1 is also a device that has a display. Specifically, the stationary device 1 is, for example, a desk clock, a music player, a television, a game device, a smartphone, a tablet PC, or a monitor device.

[0012] In this embodiment, the stationary device 1 is a table clock equipped with a rectangular display 5. Therefore, the display 5 of the stationary device 1 displays the current time. The current time may be displayed in any display form, such as numbers, hour and minute hands, or an image corresponding to the time. The current time may also be displayed using 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 quadrangle (e.g., trapezoid, parallelogram), polygon, or ellipse.

[0013] In this specification, the direction in which the display 5 is provided with respect to the stationary device 1 placed on the installation 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. A user can view the content displayed on the display 5 at least from the front. Furthermore, the upward, downward, left, and right directions when viewing the display 5 of the stationary device 1 placed on the installation surface from the front side are referred to as the upward, downward, left, and right directions of the stationary device 1, respectively.

[0014] FIG. 1 is a perspective view that schematically shows a stationary device 1. FIG. 2 is a cross-sectional view of the stationary device 1 as seen from the right side along plane Y in FIG. 3, which will be described later. FIG. 3 is a front view of the stationary device 1. FIG. 4 is a six-view diagram of the stationary device 1. As shown in FIGS. 1 to 4, the stationary device 1 includes a main body 10 that includes a display 5, and an operation assembly 30 that is provided above the main body 10. In particular, the operation assembly 30 (particularly the operation unit 31) is disposed so as to be positioned overlapping the main body 10 when viewed from above. The main body 10 houses a board 20 on which a non-contact sensor 21 and an optical sensor 22 are mounted, a control unit 40 (see FIG. 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 formed of resin. As shown in FIGS. 1 and 2 , the main body 10 in this embodiment 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 between the front surface 10a and the rear surface 10b and connecting the front surface 10a and the rear surface 10b. In particular, in this embodiment, the rear surface 10b is formed into a circle with a smaller diameter than the front surface 10a, and therefore the main body 10 is formed so that the cross-sectional area gradually decreases from the front to the rear. In other words, the side surface 10c of the main body 10 is formed into a truncated cone shape whose cross-sectional area decreases from the front to the rear.

[0016] The main body 10 may have any shape as long as one surface thereof is visible on the display 5. Therefore, the main body 10 may have any three-dimensional shape, such as a rectangular parallelepiped or 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 peripheral frame 13 that extends along the outer periphery of the housing 11 in front of the housing 11, and a cover 14 that is positioned on the front surface (display surface) of the display 5.

[0018] The housing 11 has a substantially cylindrical (or frustoconical) side wall 11a and a disk-shaped rear wall 11b. The side wall 11a is configured so that its axis X (which is the same as the axis X of the main body 10) extends substantially in the front-to-rear direction. In particular, in this embodiment, the side wall 11a is configured so that its axis X slopes slightly downward toward the rear. The rear wall 11b is connected to the side wall 11a so as to close the rear of the side wall 11a. The outer peripheral surface of the side wall 11a forms the side surface 10c of the main body 10, and the rear surface of the rear wall 11b forms the rear surface 10b of the main body 10. Electronic components such as the speaker 6, the control unit 40, and the circuit board 20 are accommodated inside the housing 11.

[0019] In this embodiment, the support member 12 is a substantially circular plate-like member made of opaque resin. The support member 12 is disposed in front of the side wall 11a of the housing 11. In particular, in this embodiment, the support member 12 is disposed so as to block 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 rearward. The display 5 is disposed in this groove 12a. The groove 12a is formed in a rectangular shape with its long sides extending in the left-right direction. Therefore, in this embodiment, as shown in FIG. 3, the display 5 is formed in a rectangular shape with its long sides extending in the left-right direction when viewed from the front.

[0021] Additionally, the support member 12 has a through-hole 12b penetrating in the front-rear direction below the groove 12a. In this embodiment, the through-hole 12b is located at the center of the support member 12 in the left-right direction, and therefore at the center of the front surface 10a of the main body 10 in the left-right direction (the same position as the openings 14b2 and 14d2 in FIG. 3). Also, in this embodiment, as shown in FIG. 3, the through-hole 12b is located at the center between the display 5 and the outer peripheral frame 13 in the up-down direction and is formed in a substantially circular shape (it is located at the same position as the openings 14b2 and 14d2 in FIG. 3 and has a similar shape to the openings 14b2 and 14d2). However, the through-hole 12b may be formed in any position and in any shape as long as it is located at a position corresponding to the position of the optical sensor 22 described below.

[0022] The outer peripheral frame 13 is an annular member that extends in front of the housing 11 along the outer periphery of the housing 11. The outer peripheral frame 13 is disposed around the support member 12 so as to surround the support member 12. Therefore, the outer peripheral frame 13 extends along the outer periphery of the main body 10 on the front surface 10a of the main body 10. The outer peripheral 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 peripheral frame 13 fixes the support member 12 to the housing 11.

[0023] In this embodiment, the outer peripheral frame 13 protrudes forward over the entire circumference beyond the front surface of the cover 14 that constitutes the front surface 10a of the main body 10. In particular, in this embodiment, as shown in Fig. 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 forms a protruding portion that protrudes forward beyond the portion of the main body 10 around the outer peripheral frame 13 (such as the cover 14), and therefore 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, the support member 12, and the outer peripheral frame 13 are configured as separate bodies. However, these components may be formed integrally in part or in whole. For example, the support member 12 and the outer peripheral frame 13 may be formed integrally, or the side wall 11a of the housing 11 and the outer peripheral frame 13 may be formed integrally.

[0025] The cover 14 is a substantially circular plate-like member, and is mainly made of transparent or translucent resin. The cover 14 is disposed in front of the support member 12 and the display 5 so as to cover the support member 12 and the display 5. Therefore, the cover 14 extends from the outer periphery of the display 5 to the outside of the display 5 (in a direction perpendicular to the front-to-rear direction). Therefore, when viewed from the front, the cover 14 is configured to overlap the display 5 and extend to the outside of the display 5. Furthermore, in this embodiment, the cover 14 is disposed on the front surface of the support member 12 and the front surface of the display 5 so as to be 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] Fig. 5 is a diagram schematically illustrating the configuration of cover 14. As shown in Fig. 5, cover 14 includes circular plate 14a made of transparent or translucent resin and multiple coating layers 14b to 14d. Circular plate 14a may be a polarizing plate that transmits only light vibrating in a certain direction, or may be a plate without a polarizing function. Circular plate 14a may also be a light guide plate.

[0027] 5, the first coating layer 14b is a layer formed of black paint with low light transmittance, and is applied to the surface (rear surface) of the circular plate 14a facing the display 5 (rear side). The first coating layer 14b has a first opening 14b1 in an area corresponding to the display 5 (an area overlapping with the display 5 when viewed from the front). In addition, the first coating layer 14b has a second opening 14b2 in an area corresponding to the through-hole 12b (the optical sensor 22) (an area overlapping with the through-hole 12b or the optical sensor 22 when viewed from the front). The color of the first coating layer 14b is not limited to black as long as it has low light transmittance.

[0028] The third painted layer 14d is a layer formed of white paint and is applied to the rear of the first painted layer 14b in an overlapping manner. Similar to the first painted layer 14b, the third painted layer 14d has a first opening 14d1 in an area corresponding to the display 5 and a second opening 14d2 in an area corresponding to the through-hole 12b (optical sensor 22). By forming the black first painted layer 14b in front of the white third painted layer 14d, the black color appears beautiful when viewed from the front.

[0029] The second coating layer 14c is a layer formed of a paint having a higher transmittance for 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 is formed of a paint having a lower transmittance for visible light of other frequencies than the above-mentioned infrared rays or visible light of certain frequencies, for example, a transmittance similar to that of the first coating layer 14b. In particular, the second coating layer 14c is formed in an area corresponding to the through-hole 12b (optical sensor 22). Therefore, the second coating layer 14c is formed in the opening 14b2 formed in the first coating layer 14b, or in the opening 14d2 formed in the third coating layer 14d, or both.

[0030] 3, the openings 14b2 and 14e2 are depicted so as to be visible in the region corresponding to the through-hole 12b (optical sensor 22) when viewed from the front. However, since the second paint layer 14c, which has a low transmittance of visible light of some frequencies, is provided, the opening corresponding to the through-hole 12b formed in the first paint layer 14b is difficult to see when viewed from the front by a user, which prevents the user from unnecessarily noticing that the optical sensor 22 is provided. On the other hand, the high transmittance of infrared light or visible light of some frequencies allows the optical sensor 22 to detect light around the stationary device 1.

[0031] In this embodiment, the first to third painted layers 14b to 14d are provided behind the circular plate 14a, but they may be provided in front of the circular plate 14a. If the display 5 itself is provided with a polarizing plate, a plate-like member without a polarizing function may be used instead of the circular plate 14a. At least some of the first to third painted layers 14b to 14d may not be provided.

[0032] In this embodiment, the support member 12 and the cover 14 extend between the display 5 and the outer peripheral frame 13, overlapping each other. The support member 12 and the cover 14 between the display 5 and the outer peripheral frame 13 constitute an enclosure 16 that is provided between the display 5, the outer peripheral frame 13, and the display and surrounds the display 5. In this embodiment, the support member 12 is configured to overlap the entire cover 14 when viewed from the front, and therefore the enclosure 16 is made up of both the support member 12 and the cover 14. However, the support member 12 may be provided only partially between the display 5 and the outer peripheral frame 13, in which case the majority of the enclosure 16 would be made up of the cover 14.

[0033] Also, the cover 14 does not have to be provided. In this case, the display 5 and the support member 12 form the front surface of the main body 10. In this case, the enclosure 16 is formed only by the support member 12.

[0034] <Board and sensor configuration> The board 20 is a member housed within the main body 10 and on which various electronic components are mounted. In this embodiment, as shown in FIG. 2, the board 20 is disposed in an area close to the front surface 10a of the main body 10, i.e., in the front portion of the main body 10. In this embodiment, the board 20 is disposed immediately rearward of the front surface 10a of the main body 10. Specifically, the board 20 is disposed immediately rearward of the support member 12 and attached to the support member 12. As shown in FIG. 2, in this embodiment, the board 20 is disposed so as to extend in a direction perpendicular to the front-rear direction, i.e., so as to extend parallel to the front surface 10a of the main body 10. As shown in FIG. 2, a non-contact sensor 21 and an optical sensor 22 are mounted on the board 20.

[0035] The non-contact sensor 21 is a sensor that detects objects around the stationary device 1, particularly in front of the stationary device 1, 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 millimeter-wave signals and receives signals reflected by surrounding objects, and detects the position of surrounding objects based on the emitted and received signals. The non-contact sensor 21 detects movement of surrounding objects when the positions of the objects around the stationary device 1 change over time. Note that such detection of the position or movement of an object based on the detection result 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 may be any sensor that can detect an object without contact. Therefore, the non-contact sensor 21 is not limited to a millimeter-wave sensor, and may be, for example, an infrared sensor, an ultrasonic sensor, a Doppler sensor, or a temperature sensor. The visible light sensor has a light projector and detects the position of an object based on the reflected wave of light projected from the light projector. The temperature sensor detects the temperature of an object around the stationary device 1, and detects the movement of a surrounding object when, for example, a high-temperature area moves.

[0037] FIG. 6 is an enlarged cross-sectional view of the upper front portion of the main body 10, taken along the same cross section as FIG. 2. As shown in FIG. 6, the non-contact sensor 21 is disposed on the front surface of the substrate 20. Therefore, the non-contact sensor 21 is disposed in the front portion of the main body 10. The non-contact sensor 21 is also disposed above the display 5 and below the outer peripheral frame 13. Therefore, the non-contact sensor 21 is disposed so that the support member 12 and the cover 14 are located in front of it. That is, the non-contact sensor 21 is disposed so as to overlap the support member 12 and the cover 14, particularly the enclosure 16, when viewed from the front. The non-contact sensor 21 transmits and receives millimeter waves that pass through the support member 12 and the cover 14 located in front of it. The non-contact sensor 21 detects the movement of an object located within a predetermined angular range centered on the direction forward from the non-contact sensor 21.

[0038] 3, the position where non-contact sensor 21 is provided when viewed from the front is indicated by a dashed line. As can be seen from Fig. 3, non-contact sensor 21 is disposed in the center (not necessarily exactly in the center, but including a location near the center) in the left-right direction of front surface 10a of main body 10 when viewed from the front. In this embodiment, non-contact sensor 21 is disposed so as to intersect with plane Y that passes through axis X of main body 10 and extends in the up-down direction.

[0039] The light sensor 22 is a sensor that detects light around 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 may be any sensor that can detect the intensity and / or color of light around the stationary device 1, or the intensity and / or color of light in a specific area around the stationary device 1. Furthermore, the light sensor 22 may be capable of detecting the light intensity continuously, or may be capable of detecting it in two or more stages.

[0040] FIG. 7 is an enlarged cross-sectional view of the same cross section as FIG. 2, enlarging the lower front portion of the main body 10. As shown in FIG. 7, the optical sensor 22 is disposed on the front surface of the substrate 20. Therefore, the optical sensor 22 is disposed in the front portion of the main body 10. The optical sensor 22 is also disposed below the display 5 and above the peripheral frame 13. Therefore, the optical sensor 22 is disposed so that the cover 14 is located in front of it. In other words, the optical sensor 22 is disposed so as to overlap with the cover 14, particularly the enclosure 16, when viewed from the front. In addition, the optical sensor 22 is disposed below the non-contact sensor 21.

[0041] 3, the position where the optical sensor 22 is provided when viewed from the front is indicated by a dashed line. As can be seen from FIG. 3, the optical sensor 22 is disposed in the center (not necessarily exactly in the center, but including a location near 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 optical sensor 22 is disposed so as to intersect with a plane Y that passes through the axis X of the main body 10 and extends in the up-down direction. In particular, in this embodiment, the optical sensor 22 is disposed in a position that overlaps with the second opening 14b2 of the first paint layer 14b and the second opening 14d2 of the third paint layer 14d when viewed from the front.

[0042] In addition, the optical sensor 22 is disposed at a position overlapping the through-hole 12b of the support member 12 when viewed from the front. As shown in FIG. 5 , in this embodiment, a light guide lens 23 is provided in front of the optical sensor 22 and inside the through-hole 12b. The front end of the light guide lens 23 faces the cover 14, and the rear end faces the optical sensor 22. The light guide lens 23 collects light over a wide angle range in front of the stationary device 1 at its front end and directs the collected light toward the light guide lens 23. Therefore, the front end of the light guide lens 23 functions as a light collecting portion for the optical sensor 22. Note that if the light guide lens 23 is not provided, the front end of the optical sensor 22 may function as a light collecting portion for the optical sensor 22.

[0043] Furthermore, in this embodiment, the light collecting portion for the light sensor 22 (the front surface of the light guide lens 23) and the main body 10 are configured so that a portion of the main body 10 is located on a line segment connecting the light collecting portion and an arbitrary point on an operation unit 31 of the operation assembly 30, which will be described later. Of these line segments, line segment Zf extending furthest forward and line segment Zr extending furthest rearward are shown in FIG. 2. Both line segments Zf and Zr intersect with components that make up the main body 10. By having a portion of the main body 10 located on the line segment connecting the light collecting portion and the operation unit 31, the effect of light emitted from the operation unit 31 on the light sensor 22 can be reduced.

[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 may be connected to the substrate via wiring.

[0045] <Configuration of operation assembly> FIG. 8 is an enlarged cross-sectional view of the operation assembly 30 taken along the same cross section as FIG. 2. FIG. 9 is an exploded perspective view of the operation assembly 30. The operation assembly 30 is used by the user to operate various functions of the stationary device 1. When the user pushes, pulls, tilts, touches, rotates, or performs other operations on the operation unit 31 of the operation assembly 30, the stationary device 1 operates in response to the operation. Specifically, in response to the operation, the display on the display 5 changes, sound is output from the speaker 6, or the light-emitting mode of the operation assembly 30 changes. The operation assembly 30 is configured so that the operation unit 31 operated by the user can emit light.

[0046] 8 and 9, the operation assembly 30 includes an operation unit 31, a base member 32, an annular member 33, an elastic member 34, and an operation unit substrate 35. The base member 32 is fixed to the upper part of the housing 11, and the operation unit 31 is attached to the base member 32 so as to be rotatable relative to the base member 32 and slidable in the direction of the axis Z of the base member 32. In addition, an illuminant 36 is provided on the operation unit substrate 35, and the operation assembly 30 is configured so that when the illuminant 36 emits light, the operation unit 31 appears to emit light.

[0047] Operation unit 31 is disposed above main body 10, and as shown in the plan view of Fig. 4, is disposed so as to overlap main body 10 when viewed from above. Operation unit 31 is also disposed behind optical sensor 22, particularly the light condensing portion for optical sensor 22. Operation unit 31 has internal member 31a, outer peripheral members 31b provided above and to the sides of internal member 31a so as to surround internal member 31a, fixing member 31c attached below internal member 31a, and magnet 31d disposed below the center of internal member 31a.

[0048] The internal member 31a is made of a material that diffuses light. The internal member 31a is made of a resin that contains a dispersed diffusing agent. When light is emitted from the light emitter 36 and incident on the internal member 31a, the internal member 31a diffuses the light to its surroundings. As shown in FIG. 8, the internal member 31a is formed in a cylindrical shape with the center of the top surface bulging upward. The outer peripheral member 31b is arranged to surround the internal member 31a and is made of a hard, transparent resin that can be held by a user. The fixing member 31c is made of a hard, transparent resin in a circular plate shape. In this embodiment, the fixing member 31c has a notch 31e recessed inward at one location on its outer periphery. The fixing member 31c is fixed below the internal member 31a by a fastener 31f such as a screw. In particular, in this embodiment, fixing member 31c is fixed to contained member 31a so that contained member 31a and fixing member 31c form groove 31g recessed radially inward on the side surface of operating unit 31. Magnet 31d is disposed between the central lower surface of contained member 31a and the central upper surface of fixing member 31c. In particular, magnet 31d is disposed so that its magnetic field lines extend in a direction perpendicular to the up-down direction (the axial direction of operating unit 31).

[0049] The base member 32 has a cylindrical portion 32a, a flange 32b protruding inward from the cylindrical portion 32a, and legs 32c protruding inward and downward from the cylindrical portion 32a. The cylindrical portion 32a is fixed to an upper portion of the side wall 11a of the housing 11 and protrudes 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 so that the rear side is higher than the front side in the direction of the axis Z of the base member 32.

[0050] Furthermore, flange 32b protrudes inward near the upper end of cylindrical portion 32a, and flange 32b fits into groove 31g formed in operating unit 31. As a result, operating unit 31 is connected to base member 32 so as to be able to rotate about the axis of base member 32. Furthermore, because the thickness of flange 32b in the vertical direction is sufficiently smaller than the width of groove 31g in the vertical direction, operating unit 31 can slide in the vertical direction relative to base member 32 (to be precise, in the axial direction of base member 32).

[0051] Two legs 32c are provided on the cylindrical portion 32a and are positioned symmetrically with respect to the axis Z of the base member 32. The legs 32c protrude inward from the inner surface of the cylindrical portion 32a. In addition, the upper end of the leg 32c is positioned lower than the upper end of the cylindrical portion 32a in the direction of axis Z, and the lower end of the leg 32c protrudes downward from the lower end of the cylindrical portion 32a in the direction of axis Z.

[0052] The annular member 33 is disposed inside the cylindrical portion 32a and below the operating unit 31. In this embodiment, the annular member 33 has two inwardly recessed notches 33a on its outer periphery. These two notches 33a are disposed symmetrically with respect to the axis Z. The annular member 33 is disposed within the base member 32 so that the legs 32c are positioned within the notches 33a. The annular member 33 is disposed so as not to rotate around the axis Z of the base member 32. Therefore, when the operating unit 31 rotates, the lower surface of the fixing member 31c of the operating unit 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 unit 31 upward, causing the upper surface of the fixing member 31c of the operating unit 31 to contact the lower surface of the flange 32b, as shown in FIG. 8.

[0053] The elastic member 34 biases the annular member 33 upward (in the axial direction of the cylindrical portion 32a and in a direction away from the operation unit substrate 35). In particular, the elastic member 34 is provided between the annular member 33 and the operation unit substrate 35 and biases the annular member 33 so as to move away from the operation unit substrate 35. Specifically, as shown in FIG. 9 , the elastic member 34 has a plurality of protrusions 34a that protrude upward in the axial Z direction of the base member 32. In this embodiment, three protrusions 34a are provided on the elastic member 34, 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 so as to move away from the operation unit substrate 35. As a result, when the operation 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 protrusion 34a. In this embodiment, the conductor 34b is provided on the lower surface of one of the protrusions provided on the front side of the elastic member 34. When the operation unit 31 is not pressed by the user, the lower surface of the protrusion 34a is spaced apart from the upper surface of the operation unit substrate 35.

[0055] The elastic member 34 biases the operation unit 31 with a force sufficient to move the operation unit 31 downward when the user presses the operation unit 31 downward. Therefore, when the user presses the operation unit 31 downward, the operation unit 31 moves downward and the elastic member 34 is deformed (particularly, the protrusion 34a is deformed), and as a result, the conductor 34b of the operation unit 31 provided on the underside of the protrusion 34a comes into contact with a contact point 35b (described later) of the operation unit substrate 35.

[0056] In this embodiment, the elastic member 34 has two inwardly recessed notches 34c on its outer periphery. These two notches 34c are positioned symmetrically with respect to the axis Z. The annular member 33 is placed in the base member 32 so that the legs 32c are positioned in the notches 34c. In addition, the elastic member 34 is fixed to the operation unit substrate 35 and therefore cannot rotate around the axis Z of the base member 32.

[0057] The operation unit board 35 is a component housed within the main body 10 and on which various electronic components are mounted. In this embodiment, the operation unit board 35 is disposed below the elastic member 34 and fixed to the housing 11 of the main body 10. The operation unit board 35 is disposed so as to extend in a direction perpendicular to the axis of the operation unit 31. As shown in FIG. 8, the operation unit board 35 is provided with a magnetic sensor 35a, a contact point 35b, and a light emitter 36.

[0058] In this embodiment, the operation unit substrate 35 has two inwardly recessed notches 35c on its outer periphery. These two notches 35c are positioned symmetrically with respect to the axis Z. The operation unit substrate 35 is placed in the base member 32 so that the legs 32c are positioned in 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 arranged on the upper surface of the operation unit substrate 35, on the axis of the operation unit 31. Therefore, the magnetic sensor 35a is arranged close to the magnet 31d of the operation unit 31 and detects the direction of the magnetic field lines generated by the magnet 31d. When the operation unit 31 rotates, the direction of the magnetic field lines generated by the magnet 31d changes. The magnetic sensor 35a can detect the rotation and angle of the operation unit 31 by detecting the direction of these magnetic field lines. In particular, in this embodiment, by using the magnet 31d and the magnetic sensor 35a, it is possible to detect the rotation and angle of the operation unit 31 while allowing the operation unit 31 to move in the axial direction.

[0060] The contact 35b is formed of a metal conductor. The contact 35b is disposed below the conductor 34b of the elastic member 34 and comes into contact with the conductor 34b when the front protrusion 34a of the elastic member 34 is deformed. The contact 35b is electrically connected to the control unit 40, and is configured so that different electrical signals are sent to the control unit 40 depending on whether the conductor 34b and the contact 35b are in contact with each other. As described above, when the operation unit 31 is not pressed by the user, the conductor 34b and the contact 35b are separated, and when the operation unit 31 is pressed by the user, the conductor 34b and the contact 35b come into contact with each other. Therefore, it is possible to determine whether the operation unit 31 is being pressed by the user using the conductor 34b and the contact 35b.

[0061] The light emitter 36 is a device that emits light in response to an electrical signal from the control unit. The light emitter 36 is, for example, an LED (Light Emitting Diode). The light emitter 36 is disposed on the upper surface of the operation unit substrate 35 below the operation unit 31. In particular, the light emitter 36 is disposed at a position that overlaps with the operation unit 31 when viewed from above. Light emitted from the light emitter 36 disposed in this manner enters the operation unit 31 through the central opening of the annular member 33 and is diffused by the inner member 31a. As a result, when light is emitted from the light emitter 36, the operation unit 31 appears to be illuminated as a whole.

[0062] As described above, in the operation assembly 30 of this embodiment, the cylindrical portion 32a is formed so that its rear side is higher than its front side in the axial Z direction of the base member 32. Furthermore, the conductor 34b is provided only on the front protrusion 34a of the elastic member 34. Therefore, when a user presses the operation unit 31, the operation unit 31 moves downward around the rear upper end of the cylindrical portion 32a as a fulcrum, deforming the front protrusion 34a of the elastic member 34, and causing the conductor 34b to contact the contact point 35b. Here, for example, if conductors are provided on all protrusions and the cylindrical portion is formed at the same height overall in the axial Z direction, when a user presses the operation unit, depending on how the user presses it, the front side of the operation unit may move down first, and then the rear side of the operation unit may move down. In this case, the conductor of the front protrusion may contact the contact point, and then the conductor of the front protrusion may separate from the contact point and the conductor of the rear protrusion may contact the contact point. This may result in the user feeling a double pressing sensation on the operation unit and the user potentially performing two unintended inputs. In contrast to this, the present embodiment has the above-described configuration, which prevents the user from feeling a double pressing sensation and prevents unintended two-time input.

[0063] In this embodiment, annular member 33, elastic member 34, and operation unit substrate 35 are provided with notches 33a, 34c, and 35c, respectively, so that these members do not interfere with leg 32c. Furthermore, fixing member 31c is positioned higher than leg 32c in the direction of axis Z, so does not interfere with leg 32c. However, fixing member 31c has only one notch 31e. This allows fixing member 31c to be easily attached to internal member 31a by first fitting the portion without notch 31e above one leg 32c, and then moving the portion with notch 31e upward along the other leg 32c. Furthermore, since only one notch 31e is provided in the fixed member 31c, the user feels a better sensation when rotating the fixed member 31c than when a plurality of notches 31e are provided.

[0064] In this embodiment, the operation assembly 30 is configured so that the user can press and rotate the operation unit 31. However, the operation assembly 30 may be configured so that the user can only press and rotate the operation unit 31. Alternatively, the operation assembly 30 may be configured so that it cannot be operated by the user. In either case, the operation assembly 30 needs to be configured to emit light. Furthermore, the operation assembly 30 may be formed in a form different from the form described above as long as it can emit light. Therefore, the operation assembly 30 may not have the light-emitting body 36, and the operation unit 31 may be coated with luminous paint. Furthermore, in this embodiment, the operation unit 31 emits light as a whole, but only a portion of it may emit light.

[0065] In this embodiment, the operation assembly 30 is formed to be inserted into the upper surface of the main body 10. However, the operation 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 so that the operation assembly 30 is located on the main body 10 when the main body 10 is viewed from above).

[0066] In this embodiment, the 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 operation unit substrate 35. Two or four or more protrusions 34a may be provided on the elastic member 34.

[0067] <Electronic component configuration> Next, the configuration of electronic components in the stationary device 1 will be described with reference to FIG. 10 . FIG. 10 is a block diagram that schematically shows the configuration of electronic components in the stationary device 1. As shown in FIG. 10 , the stationary device 1 includes a display 5, a speaker 6, a light emitter 36, a non-contact sensor 21, an optical sensor 22, a magnetic sensor 35 a, contacts 35 b, and a control unit 40. In addition, the stationary device 1 further includes a battery (not shown) that supplies power to the display 5, the control unit 40, and the like. In this embodiment, the display 5, the speaker 6, the light emitter 36, the non-contact sensor 21, the optical sensor 22, the magnetic sensor 35 a, the contacts 35 b, and the control unit 40 are housed in the main body 10; however, some of them may not be housed in the main body 10 and may be housed in the operation assembly 30, for example.

[0068] The display 5 is a device electrically connected to the control unit 40 and displays an image according to an image signal from the control unit 40. The display 5 displays an image according to a computer program executed by the control unit 40. The display 5 is, for example, a liquid crystal display, an EL (Electro Luminescence) display, or a plasma display.

[0069] The speaker 6 is a device that is electrically connected to the control unit 40 and outputs sound in accordance with an audio signal from the control unit 40. The speaker 6 also outputs sound in accordance with a computer program being executed by the control unit 40.

[0070] The light emitter 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 emitter 36 may be configured to emit light in a single color, or in a plurality of different colors. The light emitter 36 may also be configured so that its light emission intensity can be changed stepwise or continuously.

[0071] The non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contact point 35b are electrically connected to the control unit 40. Output signals from the non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contact point 35b are input to the control unit 40. Specifically, the non-contact sensor 21 inputs an output signal indicating the presence or absence of an object in front of the stationary device 1 and its position. 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 a magnetic field. In addition, the contact point 35b inputs a signal indicating whether the conductor 34b has come into contact with the contact point 35b.

[0072] <Configuration and operation of the control unit> The control unit 40 transmits control signals to the display 5, speaker 6, light emitter 36, etc. in accordance with a running computer program based on signals received from the non-contact sensor 21, the optical sensor 22, the magnetic sensor 35a, and the contacts 35b. The control unit 40 has a communication interface 41, a memory 42, and a processor 43. The communication interface 41, the memory 42, and the 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 within the main body 10. The memory 42 is a storage medium for storing data. The memory 42 includes, for example, a volatile semiconductor memory or a non-volatile semiconductor memory. In addition, the memory 42 may include removable media such as a memory card or an optical disk. 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 central processing units (CPUs) and their peripheral circuits. The processor 43 may further have other arithmetic circuits such as a logic operation unit or a numerical operation unit. The processor 43 executes various processes based on computer programs stored in the memory 42. For example, the processor 43 executes control processes for the display 5, the speaker 6, and the light emitters 36, and generates and outputs control signals to be output to the display 5, the speaker 6, and the light emitters 36.

[0075] The processor 43 also controls the functions of the stationary device 1 based on the output signal from the non-contact sensor 21, the output signal from the optical sensor 22, the output signal from the magnetic sensor 35a, and the output signal from 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 light emission of the operation assembly 30 (i.e., the light emission of the light emitters 36), the brightness of the screen of the display 5, the content displayed on the display 5, the audio output by the speaker 6, and the like based on the output signal of the non-contact sensor 21. Note that 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 light emission of the operation assembly 30, the brightness of the screen of the display 5, the content displayed on the display 5, and the audio output by the speaker 6, or may control all of these.

[0077] Specifically, for example, the processor 43 may change the light emission mode of the operation 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 the predetermined area. The processor 43 may also change the brightness of the screen of the display 5 based on whether the output signal of the non-contact sensor 21 detects a large movement of the object. For example, when an alarm or other sound 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 stop the sound output from the speaker 6, since it is considered that a person in front of the stationary device 1 has woken up. For example, when an alarm or other sound 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 stop the sound output, since it is considered that no person is in front of the stationary device 1.

[0078] The processor 43 also controls the brightness of the screen of the display 5 based on the output signal of the light sensor 22. In this embodiment, when the output signal of the light sensor 22 indicates that the area around the stationary device 1 is bright, for example, when the illuminance detected by the light sensor 22 is high, the processor 43 brightens the screen of the display 5. On the other hand, when the output signal of the light sensor 22 indicates that the area around the stationary device 1 is dark, for example, when the illuminance detected by the light sensor 22 is low, the processor 43 darkens the screen of the display 5. The output signal of the light sensor 22 may be the illuminance itself, or may be binary information indicating whether or not the illuminance exceeds a specific reference value.

[0079] Note that the processor 43 does not need to control the brightness of the screen of the display 5 so as to linearly correspond to the brightness around the stationary device 1, as long as it controls the brightness based on the output signal of the optical sensor 22. Therefore, for example, when the output signal of the optical sensor 22 indicates that the area around the stationary device 1 has suddenly become dark, the processor 43 may gradually darken the screen of the display 5, or may darken the screen of the display 5 after a certain period of time has passed 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 screen of the display 5 based on the output signal of the optical sensor 22, but the processor 43 may also control something other than the brightness of the screen of the display 5 based on the output signal of the optical 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 optical sensor 22.

[0080] Furthermore, the processor 43 controls several functions of the stationary device 1 based on the output signal of the magnetic sensor 35a and the output signal from the contact 35b. For example, when the output signal of the magnetic sensor 35a and the output signal from the contact 35b indicate that a predetermined operation is being performed on the operation unit 31, the processor 43 sets the time at which to output a sound such as an alarm from the speaker 6 and stores the time in the memory 42. Also, when the output signal of the magnetic sensor 35a and the output signal from the contact 35b indicate that another predetermined operation is being performed on the operation unit 31, the processor 43 sets the color at which the operation assembly 30 is to be illuminated and stores the color in the memory 42.

[0081] Hereinafter, with reference to FIG. 11, a specific control will be described 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 the predetermined area.

[0082] First, a method for determining whether an object in front of the stationary device 1 has moved from within a predetermined area to outside the predetermined area, for example, whether a user has moved from within a predetermined bed area to outside the bed area, based on an output signal from the non-contact sensor 21, which is a millimeter-wave sensor, will be described. FIG. 11 is a diagram schematically illustrating the detection range of the non-contact sensor 21 when the stationary device 1 is installed next to a bed B where a user is sleeping. In the example illustrated in FIG. 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 illustrated in FIG. 11, the detection range of the non-contact sensor 21 covers a certain angular range (the area indicated in gray in the figure). Furthermore, the non-contact sensor 21 can perform detection up to a distance from the non-contact sensor 21 that is sufficiently larger than the size of a typical bed B (the area indicated in gray in the figure). Therefore, the non-contact sensor 21 can detect the movement of an object up to a distance beyond the bed B within this angular range.

[0083] Furthermore, in this embodiment, the processor 43 preliminarily sets, within the detection range of the non-contact sensor 21, an area where the bed B is located, i.e., an area where the user sleeps, as a predetermined bed area. The processor 43 sets the bed area based on, for example, the user's operation of the operation unit 31 of the operation assembly 30. Alternatively, when the stationary device 1 is set to the bed area detection mode, the processor 43 may set, as the bed area, an area where object movement is detected (for example, an area where movement is detected due to the user intentionally moving around on the bed).

[0084] 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, i.e., the case where the user moves in the direction indicated by the white arrow in FIG. 11. In such a case, the output signal of the non-contact sensor 21 indicates that a large object, indicating the user's movement, is within a predetermined bed area, and then changes to indicate that the object is outside the bed area. Therefore, when the output signal of the non-contact sensor 21 indicates that the object has moved from inside the bed area to outside the bed area, the processor 43 determines that the output signal of the non-contact sensor 21 indicates that the object in front of the stationary device 1 has moved from inside the predetermined area to outside the predetermined area.

[0085] On the other hand, as shown in FIG. 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, i.e., the case where the user moves in the direction indicated by the shaded arrow in FIG. 11 . In such a case, the output signal of the non-contact sensor 21 indicates that there is no movement of an object 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 small movement, such as movement due to the user's 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 even small movement after the user's movement. Therefore, in this embodiment, the processor 43 determines that the movement of an object in front of the stationary device 1 is indicated as having occurred from inside the predetermined area to outside the predetermined area when it is detected from the output signal of the non-contact sensor 21 that there has been no even small movement of an object within the bed area for a predetermined reference time after a large movement within the bed area.

[0086] In this embodiment, 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 the predetermined area, the processor 43 causes the operation assembly 30 to emit light in a predetermined color for a predetermined period of time. As a result, the user can confirm that the stationary device 1 has recognized that the user has left the bed B.

[0087] 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 the predetermined area to outside the predetermined area, the processor 43 may change the light emission mode of the operation assembly 30 to a mode different from the light emission mode in such a case, and may emit light in any light emission mode. Therefore, for example, in such a case, the processor 43 may make the operation assembly 30 flash, or may make the operation assembly 30 emit light so that the color gradually changes. Furthermore, if the operation assembly 30 had been emitting light up until then, the processor 43 may stop the light emission.

[0088] Next, control of the brightness of the screen of the display 5 based on the output signal of the non-contact sensor 21 and the output signal of the optical sensor 22 will be described. The processor 43 makes the screen of the display 5 brighter as the illuminance detected by the optical sensor 22 increases. This makes it easier for the user to see the screen of the display 5 regardless of the brightness around the stationary device 1.

[0089] The processor 43 also changes the brightness of the screen of the display 5 depending on whether the output signal of the non-contact sensor 21 indicates that an object is moving within the bed area. When the output signal of the non-contact sensor 21 indicates that an object is moving significantly, the screen of the display 5 is brighter than when the output signal of the non-contact sensor 21 indicates that an object is not moving significantly. In this way, when the user is active in front of the stationary device 1, the screen of the display 5 is brighter, improving the user's visibility. On the other hand, when the user is sleeping in front of the stationary device 1 or when there is no user in front of the stationary device 1, the display 5 is darkened, thereby preventing the screen of the display 5 from becoming too bright while the user is sleeping, which would disturb the user's sleep or increase power consumption unnecessarily.

[0090] Furthermore, when the illuminance detected by the optical sensor 22 is equal to or greater than a predetermined illuminance, the brightness of the screen of the display 5 does not need to be changed depending on whether or not there is a large movement of an object. This prevents a situation in which, when the area around the stationary device 1 is bright, a moving hand covers the optical sensor 22, causing the screen to become dark and making it difficult for the user to distinguish the displayed content.

[0091] In this embodiment, the brightness of the screen of the display 5 is changed depending on whether a large object movement is detected or not. However, for example, if a large object movement has not been detected for a certain period of time, the screen of the display 5 may be brightened when a large object movement is detected. However, if the period during which no large object movement has been detected is shorter than the certain period of time, the screen of the display 5 may not be brightened even if a large object movement is detected. This prevents the brightness of the display 5 from being changed frequently depending on whether a large object movement is detected or not.

[0092] <Effects and Modifications> The effects of the stationary device 1 configured as described above will be described. 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. 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 disposed farther from the operation unit 31 than the non-contact sensor 21, thereby reducing the influence of the light emitted from the operation unit 31 on the detection result of the optical sensor 22. Therefore, the stationary device 1 according to the above embodiment makes it easier for the optical sensor 22 to perform its function. In other words, in the stationary device 1 according to the above embodiment, the operation unit 31 can be made to emit light without considering the influence on the optical sensor 22.

[0093] Furthermore, since the non-contact sensor 21 is disposed above the optical sensor 22, the non-contact sensor 21 is disposed at a relatively high position in the stationary device 1. It is conceivable that some obstacle may be disposed in front of the stationary device 1, and by disposing the non-contact sensor 21 at a high position, it is possible to prevent detection by the non-contact sensor 21 from being hindered by such an obstacle, making it easier to accurately detect objects in front of the stationary device 1, particularly the movement of the user. Therefore, the stationary device 1 according to the above embodiment makes it easier for the non-contact sensor 21 to perform its function.

[0094] In particular, in the above embodiment, the optical sensor 22 is disposed below the display 5, and the non-contact sensor 21 is disposed above the display 5. As a result, the optical sensor 22 is disposed at a position farther away from the operation unit 31, which further reduces the influence of light emitted from the operation unit 31 on the detection result of the optical sensor 22. Furthermore, the non-contact sensor 21 is disposed at a higher position, which further reduces the influence of obstacles.

[0095] In particular, in the above embodiment, the optical sensor 22 is disposed in the enclosure 16 between the outer peripheral frame 13 and the display 5 so as to overlap with the cover 14 when viewed from the front. As a result, the optical sensor 22 is disposed relatively close to the display 5. As described above, the brightness of the display 5 is changed based on the output signal of the optical sensor 22, so the brightness of the display 5 can be changed more appropriately in accordance with the illuminance around the display 5. Furthermore, the area of ​​the enclosure 16 between the outer peripheral frame 13 and the display 5 is a necessary area even without providing these sensors 21, 22. Therefore, there is no need to provide a separate space in the stationary device 1 for arranging these sensors 21, 22, and the stationary device 1 can be formed compactly.

[0096] Furthermore, in the stationary device 1 according to the above embodiment, the non-contact sensor 21 and the optical sensor 22 are both arranged in the center in the left-right direction (horizontal direction) of the front surface 10a of the main body 10 so as to intersect with the plane Y. By arranging the non-contact sensor 21 and the optical sensor 22 in the center in the left-right direction in this way, the movement of an object in front of the stationary device 1 and the brightness in front of the stationary device 1 are prevented from being detected unevenly.

[0097] Additionally, in the stationary device 1 according to the above embodiment, the main body 10 is configured so that a portion thereof is located on a line segment connecting an arbitrary point on the operation unit 31 and the light-condensing portion of the optical sensor 22. Therefore, even when the operation unit 31 emits light, the light is prevented from directly entering the light-condensing portion, thereby further preventing the detection result of the optical sensor 22 from being affected by the light emitted by the operation unit 31. Additionally, in the stationary device 1 according to the above embodiment, the outer peripheral frame 13 forms a protrusion that protrudes forward from the front surface of the cover 14, and the operation unit 31 is disposed behind the optical sensor 22. As a result, when the operation unit 31 emits light, the light is further prevented from entering the light-condensing portion of the optical sensor 22, thereby further preventing the detection result of the optical sensor 22 from being affected by the light emitted by the operation unit 31.

[0098] In addition, the outer peripheral frame 13 may be configured to protrude forward at the upper part of the main body 10 (i.e., above the optical sensor 22 described later), and not protrude forward in other areas (such as the lower part of the main body 10).

[0099] Alternatively, the outer peripheral frame 13 may be configured to protrude radially outward beyond the side wall 11a of the housing 11 that constitutes the side surface 10c of the main body 10. Therefore, in this case, at the upper part of the main body 10, the outer peripheral frame 13 forms a protruding portion that protrudes radially outward beyond the portion of the main body 10 around the outer peripheral frame 13 (such as the side wall 11a of the housing 11). Also, the outer peripheral 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 optical sensor 22), but not protrude radially outward in other areas (such as the lower part of the main body 10). The protruding direction of the outer peripheral frame 13 is not limited to forward and upward, and may be in any direction as long as it is possible to prevent the detection result of the optical sensor 22 from being affected by the light emitted from the operation unit 31.

[0100] Furthermore, in the stationary device 1 according to the above embodiment, the light emission 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 it is determined based on the output signal of the non-contact sensor 21 that an object has moved from within a predetermined bed area to outside the bed area, the light emission mode of the operation unit 31 is changed. As a result, when the non-contact sensor 21 detects the movement of an object, the light emission mode of the operation unit 31, which is located in a conspicuous position on the top of the stationary device 1, changes, allowing the user to easily visually confirm that the movement is being detected correctly.

[0101] Although the preferred embodiments according to 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. [Explanation of symbols]
