[0040] Figure 5 is a schematic external perspective view showing an example of the configuration of a frame member 121 according to one embodiment of the present disclosure. The details of the configuration of the frame member 121 constituting the neck pillow 12 will be mainly described with reference to Figure 5.

[0041] The frame member 121 has a base portion 121b that extends along the circumferential direction D1 of the frame member 121. The base portion 121b has an annular shape along the circumferential direction D1, with a portion of it cut out at the front of the frame member 121. The base portion 121b has a first free end E1 and a second free end E2 that are spaced apart from each other in the circumferential direction D1 at the front of the frame member 121.

[0042] The base portion 121b is positioned to surround the user's neck when the frame member 121 is placed around the neck of a user wearing the napping device 10. At this time, the base portion 121b is positioned such that the first free end E1 and the second free end E2 are located, for example, diagonally in front of the user's neck, and the cut-out portion of the base portion 121b is positioned in front of the user's neck.

[0043] The frame member 121 is positioned on the base 121b and has a mounting portion 121c to which the face shield 11, which covers the user's face when the frame member 121 is positioned around the user's neck, is attached. The mounting portion 121c has a clamping structure that supports the face shield 11 by sandwiching it. As also shown in Figure 2, the mounting portion 121c supports the entire face shield 11 by sandwiching and holding the attachment portion 111 of the face shield 11 (described later) from both sides in the thickness direction of the face shield 11.

[0044] The mounting portion 121c extends inward along the circumferential direction D1 from each of the first free end E1 and the second free end E2 of the base portion 121b. In this disclosure, "inward" corresponds, for example, to the direction toward the center of the frame member 121. However, it is not limited to this, and "inward" does not have to be a direction toward the center perfectly, but may correspond to a direction toward the center at a slight angle. "Outward" is the opposite of "inward".

[0045] Each of the pair of mounting portions 121c located at the front of the base portion 121b extends along the circumferential direction D1 from near the diagonal front of the user's neck to the front of the user's neck when the frame member 121 is positioned around the neck of a user wearing the napping device 10. The pair of mounting portions 121c hold the pair of mounting portions 111 of the face shield 11, described later, from both sides in the thickness direction of the face shield 11, thereby positioning the face shield 11 in front of the user's face so that it covers the user's face.

[0046] The frame member 121 has a support portion 121d that extends from the base portion 121b along the height direction D2 intersecting the circumferential direction D1 of the frame member 121. The support portion 121d extends symmetrically from the base portion 121b on both sides in the height direction D2, while inclining outward from the base portion 121b. The support portion 121d has a first portion that extends diagonally upward from the base portion 121b toward the outside of the base portion 121b, and a second portion that extends diagonally downward from the base portion 121b toward the outside of the base portion 121b. For example, the first portion and the second portion are the same size and have shapes that are symmetrical with respect to the base portion 121b. For example, the first portion and the second portion extend from the base portion 121b on both sides in the height direction D2 at the same angle to each other.

[0047] The frame member 121 has multiple support portions 121d. The multiple support portions 121d are arranged symmetrically in the circumferential direction D1 of the frame member 121 at the base portion 121b. For example, one support portion 121d is placed at the first free end E1 and the second free end E2 located at the front of the base portion 121b, and one is placed between the side and rear of the base portion 121b, for a total of four support portions along the circumferential direction D1.

[0048] The four support portions 121d extending from the base portion 121b along the height direction D2 are symmetrically positioned around the user's neck when the frame member 121 is placed around the neck of a user wearing the napping device 10. For example, the two support portions 121d located at the first free end E1 and the second free end E2, respectively, are positioned near the front of the user's neck. For example, the two support portions 121d located between the side and rear of the base portion 121b, respectively, are positioned near the rear of the user's neck.

[0049] The vibrating parts 121a of the frame member 121 are positioned on at least one of the sides and rear of the base 121b, causing the frame member 121 to vibrate. For example, multiple vibrating parts 121a are arranged symmetrically on the base 121b in the circumferential direction D1 of the frame member 121. For example, one vibrating part 121a is positioned on each side of the base 121b, two are positioned at the rear of the base 121b, and a total of four are positioned along the circumferential direction D1.

[0050] The four vibrating parts 121a are arranged symmetrically around the user's neck when the frame member 121 is placed on the neck of a user wearing the napping device 10. For example, two of the four vibrating parts 121a located on either side of the base 121b are positioned relative to both sides of the user's neck. For example, two of the four vibrating parts 121a located at the rear of the base 121b are positioned relative to the rear of the user's neck.

[0051] Figure 6 is a schematic external perspective view showing an example of the configuration of a face shield 11 according to one embodiment of the present disclosure. The details of the configuration of the face shield 11, which constitutes the napping device 10 together with the neck pillow 12, will be mainly described with reference to Figure 6. In the following description using Figure 6, the front / back, left / right, and up / down directions are based on the directions of the arrows in Figure 6. The up / down direction in Figure 6 corresponds to the height direction D2 in Figure 5.

[0052] As shown in Figure 2, the face shield 11 is attached to the mounting portion 121c of the frame member 121. The face shield 11 has an overall symmetrical shape in the left-right direction.

[0053] The face shield 11 used in the napping device 10 has a mounting portion 111 that is attached to the mounting object when the face shield 11 covers the user's face. In this disclosure, “mounting object” includes, for example, an object that supports the face shield 11 attached via the mounting portion 111 and allows the face shield 11 to cover the user's face. The mounting object is, for example, to which the mounting portion 111 of the face shield 11 is attached and which is positioned around the user's neck. For example, the mounting object includes a neck pillow 12. In this case, the vibrating portion 121a is positioned on the neck pillow 12 as the mounting object and vibrates the user's neck.

[0054] The mounting portion 111 includes a portion that protrudes downward from the other parts of the front of the face shield 11. One mounting portion 111 is located on each side of the front of the face shield 11. The pair of mounting portions 111 are arranged symmetrically in the left-right direction on the front of the face shield 11. The pair of mounting portions 111 are attached to a pair of mounting portions 121c on the frame member 121 of the neck pillow 12. The face shield 11 has a notch 112 located at the bottom of the front of the face shield 11. The notch 112 is located between the pair of mounting portions 111 along the left-right direction and is configured in a substantially V-shape.

[0055] The face shield 11 has a self-supporting shape when the attachment portion 111 is attached to the neck pillow 12 to which it is to be attached. In this disclosure, "self-supporting shape" includes a three-dimensional shape that is maintained independently without using, for example, support columns such as a frame as structural members for the face shield 11. The face shield 11 has fold lines 113 that maintain the self-supporting shape. Multiple fold lines 113 are arranged on the face shield 11. The multiple fold lines 113 are arranged symmetrically in the left-right direction.

[0056] The face shield 11 has a folding structure that transitions between a first state in which the entire structure is self-supporting and a second state in which the entire structure is folded along a fold line 113. In this disclosure, "first state" means, for example, the state shown in Figure 6. "Second state" means, for example, the state in which the face shield 11 has a folded shape when it is folded into a thin, flat shape.

[0057] As shown in Figures 2 and 6, the face shield 11 has a reflective portion 114 located on the inner surface of the face shield 11 when it maintains its self-supporting shape, which reflects only blue light into the interior of the face shield 11. In addition, as shown in Figures 1 and 6, the face shield 11 has a light-shielding portion 115 laminated on the reflective portion 114 and located on the outer surface of the face shield 11, which blocks light from the outside.

[0058] The face shield 11 has a laminated structure including at least two layers, with a reflective portion 114 placed in the innermost layer and a light-shielding portion 115 placed in the outermost layer. The reflective portion 114 includes blue film and sheets, etc. The light-shielding portion 115 includes, for example, a black-based material that absorbs and blocks light. The light-shielding portion 115 includes, for example, black film and sheets, etc. However, it is not limited to these, and each of the reflective portion 114 and the light-shielding portion 115 may have any configuration that can achieve its function. For example, the light-shielding portion 115 may be made of woven fabric, cloth, and sponge, etc.

[0059] Figure 7A is a schematic diagram showing an example of the arrangement of the irradiation unit 15 of the napping device 10 in Figure 3. Figure 7B is a schematic diagram showing an example of the function of the irradiation unit 15 of the napping device 10 in Figure 3. Note that in Figure 7B, the arrangement of the irradiation unit 15 is shown conceptually for ease of understanding, and differs from the actual arrangement of the irradiation unit 15 schematically shown in Figure 7A. Referring to Figures 7A and 7B, we will mainly explain an example of the arrangement and function of the irradiation unit 15 when a user is wearing the napping device 10.

[0060] The illumination unit 15 of the napping device 10 is positioned, for example, on the inner surface of the face shield 11, i.e., on the surface of the reflective part 114. The illumination unit 15 is positioned directly above the user's eyes when the face shield 11 is positioned on the user's face in a self-supporting shape, and it illuminates the reflective part 114 and the user's eyes with white light. The illumination unit 15 operates, for example, when it receives a control signal from the control unit 19 to wake up a napping user. At this time, the illumination unit 15 illuminates the user's eyes with white light at an optimal intensity that allows the user to perceive a moderate brightness even with their eyes closed.

[0061] As shown on the left side of Figure 7A, if the irradiating unit 15 is positioned directly in front of the user's eyes, the user will receive strong white light even with their eyes closed, causing glare and discomfort. Conversely, as shown in the center of Figure 7A, if the irradiating unit 15 is positioned diagonally behind and above the user's eyes, the user will receive weak white light with their eyes closed and will not perceive brightness. On the other hand, as shown on the right side of Figure 7A, by positioning the irradiating unit 15 directly above the user's eyes, it irradiates the user's eyes with white light at an optimal intensity that allows the user to perceive moderate brightness even with their eyes closed.

[0062] As shown in Figure 7B, the irradiating unit 15 emits white light not only to the user's eyes but also to the reflecting unit 114. The reflecting unit 114, located on the inner surface of the face shield 11, reflects only the blue light from the white light emitted by the irradiating unit 15 into the interior of the face shield 11. For example, white light emitted from the irradiating unit 15 toward the reflecting unit 114 becomes blue light in the reflecting unit 114 and is emitted to the user's eyes located inside the face shield 11. When the user's eyes are closed, they primarily perceive the white light emitted directly from the irradiating unit 15 into their eyes. On the other hand, when the user's eyes are open, they primarily perceive the blue light emitted indirectly from the irradiating unit 15 to their eyes via the reflecting unit 114, in addition to or instead of the white light emitted directly from the irradiating unit 15 into their eyes.

[0063] Figure 8 is a flowchart illustrating an example of the operation of the nap device 10 shown in Figure 3. Referring to Figure 8, we will mainly explain an example of the processing flow performed by the control unit 19 of the nap device 10 shown in Figure 3. Figure 8 shows a series of processing steps performed by the control unit 19 when, for example, a user who is napping while wearing the nap device 10 is woken up.

[0064] In step S101, the control unit 19 of the napping device 10 acquires biological information related to the sleep of the user who is napping using the sensor unit 17.

[0065] In step S102, the control unit 19 of the nap device 10 measures the user's sleep state based on the biological information acquired by the sensor unit 17 in step S101. In this disclosure, "sleep state" means, for example, the depth of sleep, such as REM sleep and non-REM sleep.

[0066] In step S103, the control unit 19 of the nap device 10 determines whether or not to start a wake-up control based on the sleep state measured in step S102. For example, if the control unit 19 determines that the user is about to transition from light REM sleep to deep non-REM sleep, it starts a wake-up control. For example, if the control unit 19 determines that the numerical value of the biometric information acquired in step S101 has fallen within a predetermined range relative to the boundary value between REM sleep and non-REM sleep, it starts a wake-up control. If the control unit 19 determines to start a wake-up control, it executes the process in step S104. If the control unit 19 determines not to start a wake-up control, it repeats the process from step S101.

[0067] In step S104, if the control unit 19 of the napping device 10 determines in step S103 that it has started control for waking up, it activates at least one of the irradiation unit 15, the vibration unit 121a, and the output unit 16.

[0068] For example, the control unit 19 activates the irradiation unit 15 to emit white light from the light source of the irradiation unit 15 when waking the user. For example, the control unit 19 activates the vibration unit 121a to apply vibrations with a predetermined vibration pattern to the user's neck when waking the user. For example, the control unit 19 activates the output unit 16 to output sound from the speaker of the output unit 16 when waking the user. For example, the control unit 19 activates the output unit 16 to output a scent from the diffuser of the output unit 16 when waking the user.

[0069] In step S105, the control unit 19 of the sleeping device 10 determines whether or not it has received a request from the user to stop the operation. For example, the control unit 25 of the user's own terminal device 20 receives input operations via the input unit 23 to stop the operation of each component of the sleeping device 10 that was operated in step S104. The control unit 25 transmits the operation stop request information obtained by the input unit 23 to the sleeping device 10 via the communication unit 21. When the control unit 19 of the sleeping device 10 receives the request information from the terminal device 20 via the communication unit 13, it determines that it has received a request from the user to stop the operation. If the control unit 19 determines that it has received a request from the user to stop the operation, it executes the process in step S106. If the control unit 19 determines that it has not received a request from the user to stop the operation, it repeats the process from step S105 again.

[0070] In step S106, if the control unit 19 of the napping device 10 determines that it has received a request from the user to stop operation in step S105, it stops the operation of each component that was operated in step S104.

[0071] The face shield 11 and napping device 10 according to the above embodiment offer improved convenience. For example, the convenience of the face shield 11 and napping device 10 is improved when a user is napping while seated. The face shield 11 used in the napping device 10 has a mounting portion 111 that is attached to the mounting object when the face shield 11 covers the user's face. The face shield 11 has a self-supporting shape when the mounting portion 111 is attached to the mounting object.

[0072] As a result, the face shield 11 can conceal the user's face while they are napping, preventing others around them from seeing their sleeping face. In addition, due to its self-supporting shape, the face shield 11 can be positioned away from the user's head, which helps to maintain the user's hair and makeup. Thus, the convenience of the face shield 11 is improved.

[0073] The face shield 11 has fold lines 113 that maintain its self-supporting shape. As a result, the face shield 11 can easily achieve a self-supporting shape by the fold lines 113 without using rigid strength members made of materials such as metal and resin as a frame. Therefore, the face shield 11 can avoid harm such as the strength members breaking and piercing the user's face. The face shield 11 can improve safety for users who are napping.

[0074] The face shield 11 has a folding structure that transitions between a first state in which the entire structure is self-standing and a second state in which the entire structure is folded along the fold line 113. This allows the face shield 11 to be folded compactly, making it easy for the user to carry. When the face shield 11 is not in use by the user, it can be folded along the fold line 113 to allow for space-saving storage. The user can easily use the face shield 11 by unfolding it and attaching it to the object to be attached when taking a nap.

[0075] The face shield 11 has a notch 112 located at the bottom of its front surface. This allows the user to see outside the face shield 11 through the notch 112, even when their face is covered by the face shield 11. The user can easily see outside the face shield 11 simply by lowering their gaze. Therefore, the user can feel a sense of openness even when their face is covered by the face shield 11. In addition, the face shield 11 can have a gap created by the notch 112 so that the user does not have difficulty breathing. This reduces breathlessness and allows the user to take a nap comfortably even when their face is covered by the face shield 11.

[0076] The face shield 11 has a reflective part 114 located on the inner surface of the face shield 11 when it maintains its self-supporting shape, which reflects only blue light into the interior of the face shield 11. As a result, when a user opens their eyes immediately after waking up with their face covered by the face shield 11 and looks at the inner surface of the face shield 11, they can perceive the blue light of a simulated blue sky. The face shield 11 can also make a user who has just woken up from a nap and opened their eyes perceive blue light, giving them a feeling similar to looking at a blue sky, and thus helping them wake up comfortably.

[0077] The face shield 11 has a light-shielding portion 115 that is laminated on the reflective portion 114 and located on the outer surface of the face shield 11, blocking light from the outside. This reduces the visibility of the inside of the face shield 11 when viewing it from the outside. Therefore, the face shield 11 can hide the face of a user who is napping so that others around them cannot see their sleeping face.

[0078] The napping device 10 has a vibrating unit 121a that is positioned on the mounting object and applies vibration to the user's neck. When waking the user, the napping device 10 operates the vibrating unit 121a to apply vibration having a predetermined vibration pattern to the user's neck. In this way, the napping device 10 can apply vibration to the neck of a user wearing a neck pillow 12, for example, which is made of a frame member 121, and make the user feel vibration having a predetermined vibration pattern. Therefore, the napping device 10 can also, for example, apply vibration having a predetermined vibration pattern to the user's neck when waking a napping user, and wake the user comfortably by the vibration they feel.

[0079] A similar effect applies to the irradiation unit 15 and output unit 16 controlled by the control unit 19 of the napping device 10 in step S104 of Figure 8. For example, the napping device 10 can irradiate the user with white light from the light source of the irradiation unit 15, allowing the user, who is napping with their eyes closed, to perceive brightness from the white light as pseudo-sunlight. The napping device 10 can also, for example, irradiate the user's closed eyes with white light when waking a napping user, allowing the user to wake up comfortably with brightness similar to what they perceive as sunlight.

[0080] The illumination unit 15 is positioned directly above the user's eyes when the face shield 11 is positioned on the user's face in a self-supporting shape, and it illuminates the reflective unit 114 and the user's eyes with white light. As a result, the napping device 10 can illuminate the user's eyes with white light at an optimal intensity that allows the user to perceive a moderate level of brightness even with their eyes closed. Therefore, the napping device 10 can also comfortably wake up a napping user.

[0081] For example, the napping device 10 emits white light from the light source of the illumination unit 15 and emits blue light to the user via the reflector unit 114, thereby allowing the user, who has just woken up and opened their eyes, to experience the blue light of a simulated blue sky. The napping device 10 can also, for example, emit blue light into the user's eyes, which are open immediately after waking up from a nap, giving the user a sensation similar to looking at a blue sky, thus helping the user wake up comfortably.

[0082] For example, the napping device 10 can stimulate the hearing of a napping user by emitting sound from the speaker of the output unit 16. The napping device 10 can also stimulate the user's own hearing and help them wake up smoothly from their nap by playing a sound to the user when waking them up.

[0083] For example, the napping device 10 can stimulate the sense of smell of a napping user by emitting a scent from the diffuser of the output unit 16. The napping device 10 can also stimulate the user's sense of smell by having them smell a scent when waking them up, thus facilitating a smooth and comfortable awakening from their nap.

[0084] The napping device 10 can also stimulate the user's sight, hearing, smell, and touch in an integrated manner by combining light, sound, smell, and vibration. Therefore, the user can wake up smoothly and comfortably from a nap while stimulating multiple senses simultaneously.

[0085] The nap device 10 measures the user's sleep state based on biometric information acquired by the sensor unit 17, and determines whether or not to initiate control to wake the user based on the measured sleep state. This allows the nap device 10 to monitor the user's sleep state and initiate control to wake the user just before the user transitions from light REM sleep to deep non-REM sleep. Therefore, the nap device 10 can smoothly and comfortably wake the user from a nap before the user transitions to deep non-REM sleep.

[0086] The attachment targets include the neck pillow 12. This allows the napping device 10 to be configured as a neck pillow 12 to which the face shield 11 is attached via the attachment part 111. Therefore, the napping device 10 allows the user to conceal their face with the face shield 11 so that others around them cannot see their sleeping face. In addition, the napping device 10 can also stably position the user's head without it wobbling by using the neck pillow 12. Furthermore, the napping device 10 can also position the face shield 11 away from the user's head by using the neck pillow 12, which helps to maintain the user's hair and makeup without disturbing them. As a result, the convenience of the neck pillow 12 and the napping device 10 is improved.

[0087] It will be apparent to those skilled in the art that this disclosure can be implemented in other predetermined forms besides the embodiments described above without deviating from its spirit or essential features. Therefore, the prior description is illustrative and not limiting. The scope of the disclosure is defined not by the prior description but by the added claims. Any modifications within their equivalent scope are included therein.

[0088] For example, the shape, pattern, size, arrangement, orientation, type, and number of each component described above are not limited to those shown in the above description and drawings. The shape, pattern, size, arrangement, orientation, type, and number of each component may be configured arbitrarily as long as they can achieve their function. The frame member 121, neck pillow 12, face shield 11, and napping device 10 shown are functional concepts, and the specific form of each component is not limited to those shown.

[0089] For example, the functions included in each component or step can be rearranged in a logically consistent manner, and multiple components or steps can be combined into one or separated.

[0090] In the above embodiment, the face shield 11 was described as having a fold line 113 that maintains its self-supporting shape, but it is not limited to this. The face shield 11 does not have to have a fold line 113. The face shield 11 may maintain its self-supporting shape by any other configuration in place of or in addition to the fold line 113.

[0091] In the above embodiment, the face shield 11 was described as having a folding structure that transitions between a first state in which the entire structure is self-supporting and a second state in which the entire structure is folded along the fold line 113, but it is not limited to this. The face shield 11 does not have to have a folding structure. The face shield 11 may have a structure that maintains a self-supporting shape without folding not only when in use, but also when carrying and storing.

[0092] In the above embodiment, the face shield 11 was described as having a notch 112 located at the lower front surface, but it is not limited to this. The notch 112 of the face shield 11 may be located at a different position from the lower front surface. Alternatively, the face shield 11 may not have a notch 112.

[0093] In the above embodiment, the face shield 11 was described as having a reflective portion 114 located on the inner surface of the face shield 11 when maintaining its self-supporting shape, which reflects only blue light into the face shield 11. However, it is not limited to this. The reflective portion 114 of the face shield 11 may reflect light of other colors into the face shield 11 instead of, or in addition to, blue light. Alternatively, the face shield 11 may not have a reflective portion 114.

[0094] In the above embodiment, the face shield 11 was described as having a light-shielding portion 115 that is laminated on the reflective portion 114 and located on the outer surface of the face shield 11 to block light from the outside, but it is not limited to this. The light-shielding portion 115 of the face shield 11 may be arranged relative to the reflective portion 114 in any manner other than lamination. The face shield 11 is not limited to a laminated structure including at least two layers, with the reflective portion 114 arranged in the innermost layer and the light-shielding portion 115 arranged in the outermost layer, and may have any other structure that can achieve its function. Alternatively, the face shield 11 may not have a light-shielding portion 115.

[0095] In the above embodiment, the napping device 10 was described as having a face shield 11 positioned in a self-supporting shape relative to the user's face, positioned directly above the user's eyes, and having an illuminating unit 15 that irradiates a reflective unit 114 and the user's eyes with white light. However, it is not limited to this. The illuminating unit 15 of the napping device 10 may be positioned offset from directly above the user's eyes when the face shield 11 is positioned in a self-supporting shape relative to the user's face. The illuminating unit 15 may irradiate only one of the reflective unit 114 and the user's eyes with white light. The illuminating unit 15 may irradiate light of another color in place of or in addition to white light. Alternatively, the napping device 10 may not have an illuminating unit 15. In this case, any other light source device different from the napping device 10 may irradiate the reflective unit 114 and the user's eyes with white light.

[0096] In the above embodiment, the napping device 10 was described as measuring the user's sleep state based on biometric information acquired by the sensor unit 17 and determining whether or not to start control to wake the user based on the measured sleep state, but it is not limited to this. The napping device 10 may perform other processes in lieu of or in addition to such determination processing. For example, the napping device 10 may start control to wake the user when a predetermined time has elapsed, such as a timer function. For example, the napping device 10 may start control to wake the user when a predetermined time is reached, such as an alarm function. The napping device 10 may implement a timer function or an alarm function by, for example, acquiring timer time information or alarm time information input using the input unit 23 of the terminal device 20 used by the user from the terminal device 20. In such cases, the napping device 10 does not need to have a sensor unit 17 that acquires biometric information related to the sleep of the napping user.

[0097] In the above embodiment, the napping device 10 was described as having a vibrating part 121a that is positioned on the mounting object and vibrates against the user's neck, but it is not limited to this. The napping device 10 does not have to have a vibrating part 121a. Alternatively, the vibrating part 121a may be positioned in the napping device 10 at a location different from the mounting object. For example, the vibrating part 121a may be positioned in the face shield 11.

[0098] In the above embodiment, the napping device 10 was described as activating the vibration unit 121a to wake the user and applying vibrations having a predetermined vibration pattern to the user's neck, but it is not limited to this. The napping device 10 does not need to activate the vibration unit 121a to wake the user. Alternatively, the napping device 10 may apply simple vibrations without a vibration pattern to the user's neck.

[0099] In the above embodiment, the mounting object was described as including the neck pillow 12, but is not limited thereto. The mounting object may include any other object to which the mounting portion 111 of the face shield 11 is attached. The mounting object may include an object positioned at a location other than the user's neck. For example, the mounting object may include a chair. The chair may be, for example, positioned on an office desk, or installed inside a train, vehicle, or airplane. In this case, the face shield 11 may be able to transition between a usage state in which it covers the user's face from the front, using the mounting portion 111 attached to the chair as a pivot point, and a retreat state in which it is positioned above the user's head and does not cover the user's face.

[0100] In the above embodiment, the napping device 10 is described as operating at least one of the vibration unit 121a, the irradiation unit 15, and the output unit 16 when waking up a user who is napping, but it is not limited to this. The napping device 10 may also operate at least one of the vibration unit 121a, the irradiation unit 15, and the output unit 16 when the user is falling asleep, in order to facilitate the user falling asleep and smoothly transitioning to napping.

[0101] In the above embodiment, the napping device 10 was described as receiving a request from the user to stop its operation via the terminal device 20, but it is not limited to this. The napping device 10 may have an input unit such as a switch for stopping the operation of each component that was operated in step S104 of Figure 8. The napping device 10 may stop the operation of each component that was operated in step S104 of Figure 8 based on the user's operation of the input unit.

[0102] In the above embodiment, the napping system 1 was described as having a napping device 10 and a terminal device 20, but it is not limited to this. The napping system 1 may consist only of the napping device 10 without the terminal device 20. In this case, the functions that are realized using the terminal device 20 as described in the above embodiment may be realized by the napping device 10 itself.

[0103] Figure 9A is a schematic external perspective view showing the high state of the frame member 121 according to the first modified example. Figure 9B is a schematic external perspective view showing the low state of the frame member 121 of Figure 9A. An example of the configuration and function of the frame member 121 according to the first modified example will be mainly described with reference to Figures 9A and 9B.

[0104] In the above embodiment, as shown in Figure 5 for example, the overall height of the frame member 121 is constant, but is not limited thereto. The overall height of the frame member 121 may be variable. In this case, the frame member 121 may further have an adjustment part 121e located on the base 121b that changes the height of the frame member 121. For example, the adjustment part 121e is arranged to extend from a support part 121d located at the front of the frame member 121 to a support part 121d located at the rear of the frame member 121, centering on the portion where the vibrating part 121a is located on each of the sides of the base 121b.

[0105] The adjustment section 121e has a divided structure that divides the support section 121d in the height direction D2 into a first part extending from the base 121b to one side in the height direction D2 as shown in Figure 5, and a second part extending from the base 121b to the other side in the height direction D2. The divided structure of the adjustment section 121e includes a support column 121f that extends along the height direction D2. The adjustment section 121e changes the distance in the height direction D2 between the first and second parts of the support section 121d by tilting the three support columns 121f of the divided structure, which are located on each side of the base 121b, at an angle with respect to the height direction D2.

[0106] For example, the overall width of the adjustment section 121e along the height direction D2 is largest when the three support columns 121f are arranged parallel to each other along the height direction D2, as shown in Figure 9A. On the other hand, the overall width of the adjustment section 121e along the height direction D2 is smallest when the three support columns 121f are inclined most diagonally with respect to the height direction D2, as shown in Figure 9B. The adjustment section 121e changes the overall width along the height direction D2 continuously or in steps between, for example, the high state of the frame member 121 shown in Figure 9A and the low state of the frame member 121 shown in Figure 9B.

[0107] The frame member 121 further includes an adjustment part 121e that changes the height of the frame member 121, allowing the frame member 121 to be adjusted to an appropriate height according to the user's neck length. Generally, neck lengths vary from user to user. Even in such cases, the frame member 121 can adjust the height of the frame member 121 to suit each user, providing a consistent sense of stability when supporting the user's head for a variety of users.

[0108] In the first modified example described above, the adjustment section 121e is described as having the divided structure shown in Figures 9A and 9B, but is not limited thereto. The adjustment section 121e may have a folding structure that folds in a straight line, such that the first and second parts of the support section 121d move parallel to each other along the height direction D2 while facing each other along the height direction D2, thereby changing the height of the frame member 121.

[0109] Figure 9C is a schematic external perspective view showing the folded state of the frame member 121 in Figure 9A. Referring to Figure 9C, other examples of the configuration and function of the frame member 121 according to the first modified example will be mainly described.

[0110] In the above embodiment, for example, as shown in Figure 5, the frame member 121 does not have a folding structure, but is not limited thereto. As shown in Figure 9C, the frame member 121 may have a folding section 121g that transitions between an assembled state in which the entire structure is assembled and a folded state in which the entire structure is folded.

[0111] For example, as shown in Figure 9A, the folding part 121g is located in the center of the rear of the base part 121b. The folding part 121g has an asymmetrical axis of rotation R that is inclined with respect to the central axis of the frame member 121, and enables the folding of the frame member 121 by twisting one half of the frame member 121 toward the other half. The folding part 121g enables the folding of the frame member 121 so that one half and the other half do not overlap in the height direction D2, compared to when the frame member 121 is folded so that one half and the other half overlap in the height direction D2 by a symmetrical axis of rotation that coincides with the central axis of the frame member 121.

[0112] The frame member 121 has a folding section 121g, which allows it to be folded compactly, making it easy for the user to carry the frame member 121. When the frame member 121 is not in use by the user, it can be folded at the folding section 121g, enabling space-saving storage. The folding section 121g has an asymmetrical axis of rotation R that is inclined with respect to the central axis of the frame member 121, which allows the frame member 121 to be folded so that one half and the other half do not overlap in the height direction D2, thereby achieving a more compact fold.

[0113] In the first modified example described above, the folding portion 121g is described as having an asymmetrical axis of rotation R inclined with respect to the central axis of the frame member 121, but it is not limited to this. The folding portion 121g may also have a symmetrical axis of rotation that coincides with the central axis of the frame member 121.

[0114] Figure 10A is a schematic external perspective view showing an example of the configuration of the frame member 121 according to the second modified example. Figure 10B is a front view of the frame member 121 in Figure 10A. Figure 10C is a side view of the frame member 121 in Figure 10A. An example of the configuration and function of the frame member 121 according to the second modified example will be mainly described with reference to Figures 10A to 10C.

[0115] In the above embodiment, the frame member 121 was described as having the shape shown in Figure 5, but it is not limited to this. The frame member 121 may have a shape similar to a neck corset, for example, as shown in Figures 10A to 10C.

[0116] The frame member 121 according to the second modified example has a base portion 121b extending along the circumferential direction D1 of the frame member 121, and a mounting portion 121c disposed on the base portion 121b to which a face shield 11 covering the user's face is attached when the frame member 121 is positioned around the user's neck. In addition, the frame member 121 has a vibrating portion 121a disposed on at least one of the side and rear of the base portion 121b to vibrate the frame member 121. For example, the multiple vibrating portions 121a are arranged symmetrically on the base portion 121b along the circumferential direction D1 of the frame member 121. For example, one vibrating portion 121a is disposed on each side of the base portion 121b, and one is disposed on the rear of the base portion 121b, for a total of three vibrating portions along the circumferential direction D1.

[0117] The frame member 121 according to the second modification further includes, in addition to the components common to the embodiment described above, a belt 121h that connects the first free end E1 and the second free end E2 of the base 121b along the circumferential direction D1. The belt 121h is intended to increase the gap between the first free end E1 and the second free end E2 so that the corset shape of the frame member 121 does not compress the user's neck.

[0118] The frame member 121 in the second modified example may be configured to have a variable height, similar to the first modified example. In this case, the frame member 121 may be, for example, a pair of members having a similar corset shape, which are arranged on the inside and outside along the circumferential direction D1 and bonded together. The frame member 121 may be configured to have a variable height by offsetting one of the pair of members in the height direction D2 relative to the other so that they can be bonded together.
