Description

Technical Field

[0001] The present invention relates to a ring-type device for operating an information processing device. Background Art

[0002] As a device for operating an information processing device, a ring-type operating device worn on a finger has appeared (WO 2023 / 286316), and has attracted attention in recent years as an operation input unit to replace a conventional mouse, keyboard, touch panel, etc.

[0003] From the viewpoint of reducing the burden on the finger, it is preferred that such a ring-type device is as light as possible. In addition, the fit when worn on the finger is also important. That is, it is important, for example, to ensure that a stable posture can be maintained when worn on the finger and to prevent the finger or hand from being forced into an unnatural posture or feeling a sense of discomfort during wearing. In addition, whether various operations are easy to perform when worn on the finger, that is, operability is also important. Summary of the invention

[0004] A ring-type device that is operated while being worn on a finger needs to have operability that allows various input operations to be performed by relying on the feel of the finger without looking at the hand wearing the ring-type device. On the other hand, from the perspective of wearability on the finger, the ring-type device is designed to be as small as possible (especially a configuration with a narrow width in the insertion direction of the finger), and the size of the operating part such as a button for input operation must also be small. Therefore, a device that allows the user to identify the operating part only by the touch of a finger without looking at the ring-type device is needed. In particular, when a plurality of operating parts are provided, it is necessary to allow the user to distinguish the configuration and difference of the operating parts only by the touch of a finger, and to prevent erroneous operations such as erroneously operating one operating part while operating another operating part.

[0005] An object of the present invention is to provide a technology capable of improving the operability of an operating portion in a ring-type device having a plurality of operating portions.

[0006] To achieve the above object, the ring-shaped device of the present invention comprises:

[0007] an annular body having an inner surface surrounding the wearing space and an outer surface opposite to the inner surface;

[0008] A first operating portion, which is disposed on the outer surface;

[0009] a second operating portion provided on the outer surface at a position different from that of the first operating portion; and

[0010] A rib is provided on the outer surface between the first operating portion and the second operating portion.

[0011] To achieve the above object, the ring-shaped device of the present invention comprises:

[0012] A main body having an outer surface and an inner surface, wherein an operation unit is arranged on the outer surface and the inner surface forms a wearing space;

[0013] a first arm connected to a first end of the main body in a direction surrounding the wearing space and facing the inner surface across the wearing space; and

[0014] a second arm connected to a second end of the main body opposite to the first end in the direction and facing the inner surface across the wearing space, wherein

[0015] The first arm and the second arm are both rotatably attached to the body at a variable relative distance from the inner surface, and

[0016] A tip of the first arm when closest to the inner surface is closer to a rotation axis of the second arm than a tip of the second arm when closest to the inner surface.

[0017] Further features of the present invention will become apparent from the following description of exemplary embodiments with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In the following examples, embodiments of the present disclosure will be described by way of example. However, the configurations disclosed in the following examples (such as the functions, materials, shapes, and relative configurations of components) illustrate examples of forms related to the scope of the claims, and are not intended to limit the scope of the claims to the configurations disclosed in these examples. In addition, the problems solved by the configurations disclosed in the following examples or the operations or effects obtained from the disclosed configurations are not intended to limit the scope of the claims.

[0047] First embodiment

[0048] Will refer to Figures 1A to 25B A ring-type device 1 according to a first embodiment of the present invention is described.

[0049] Overview of Ring Type Device

[0050] Figures 1A to 1C : is a schematic diagram showing the configuration of a ring-type device 1 according to a first embodiment of the present invention. Figure 1A This is a front view of the ring-type device 1 when the ring-type device 1 is viewed in the insertion direction of the finger. Figure 1B is from Figure 1A The top view of the ring-type device 1 observed by the arrow A in FIG. 1 shows the structure of the operating surface of the ring-type device 1 . Figure 1C is from Figure 1A A side view of the ring-type device 1 as viewed from the direction of arrow B in FIG.

[0051] like Figure 1AAs shown, the ring-type device 1 of the present embodiment has a generally annular outer shape and is configured so that a user can insert a finger F into a center hole. More specifically, the ring-type device 1 includes a main body 2, a first arm 3, and a second arm 4, which are connected in a ring shape to form a wearing space FS into which the user's finger F can be inserted (they form an annular body surrounding the wearing space FS).

[0052] Here, in this specification, the term "annular" refers not only to an annular structure that completely closes the periphery of the wearing space FS, but also a shape structure that is partially interrupted and discontinuous (such as a roughly C-shape) but has a roughly annular shape is also referred to as an annular shape.

[0053] The main body 2 has an outer cover 20 that is substantially arc-shaped, and the outer cover 20 has a concave arc-shaped inner surface 21 that forms a wearing space FS and an outer surface 22 that is opposite to the inner surface 21 .

[0054] The first arm 3 is connected to the first end 23 which is one end of the main body 2 in the direction surrounding the wearing space FS, and extends in a substantially arcuate manner along one direction (first direction) in the surrounding direction from the first end 23 of the main body 2. The first arm 3 has a concave arcuate inner surface 31 forming the wearing space FS, and the inner surface 31 faces the inner surface 21 of the main body 2 across the wearing space FS. The first arm 3 is rotatably attached to the first end 23 of the main body 2 in such a manner that the relative distance between the inner surface 31 and the inner surface 21 of the main body 2 can be changed.

[0055] The second arm 4 is connected to the second end 24 which is the other end of the main body 2 in the direction surrounding the wearing space FS, and extends in a substantially arcuate manner along the other direction (second direction) in the surrounding direction from the second end 24 of the main body 2. The second arm 4 has a concave arcuate inner surface 41 forming the wearing space FS, and the inner surface 41 faces the inner surface 21 of the main body 2 across the wearing space FS. The second arm 4 is rotatably attached to the second end 24 of the main body 2 in such a manner that the relative distance between the inner surface 41 and the inner surface 21 of the main body 2 can be changed.

[0056] In the direction of closing the wearing space FS, that is, in the direction of narrowing the relative distance relative to the inner surface 21 of the main body 2, the first arm 3 is urged by the torsion coil spring 32s as the first urging member, and the second arm 4 is urged by the torsion coil spring 42s as the second urging member. Therefore, the first arm 3 and the second arm 4 can each rotate relative to the main body 2 according to the thickness (diameter) of the finger F inserted into the wearing space FS. In other words, the relative distance between the first arm 3 and the second arm 4 and the inner surface 21 of the main body 2 changes according to the thickness (diameter) of the finger F inserted into the wearing space FS, and the width of the wearing space FS can be changed.

[0057] Here, the rotation axis 32x of the first arm 3 relative to the rotation axis 32 of the main body 2 and the rotation axis 42x of the second arm 4 relative to the rotation axis 42 of the main body 2 are both oriented along the insertion direction ID of the finger F relative to the wearing space FS. In the present embodiment, the rotation axis 32x, the rotation axis 42x, and the insertion direction ID are configured to be parallel to each other, but the present invention is not limited to this configuration. As long as the same effect as that of the present embodiment can be obtained, that is, the width of the wearing space FS can be changed without affecting the wearability and operability, the rotation axis 32x, the rotation axis 42x, and the insertion direction ID can be configured to be inclined to each other within a predetermined range instead of being parallel to each other.

[0058] The structure of the main body

[0059] The main body 2 has a touch sensor 5 and a button switch 6 built into the outer surface 22 of the outer cover 20. The touch sensor 5 and the button switch 6 are arranged side by side in a direction surrounding the wearing space FS. Figure 1B As shown, the button switch 6 is symmetrically arranged in the insertion direction ID of the finger F. A first finger rest 223 and a second finger rest 224 are arranged on both sides of the operating portion of the outer surface 22 in which the touch sensor 5, the button switch 6, etc. are arranged in the surrounding direction. The first finger rest 223 and the second finger rest 224 are formed in a concave shape so that, for example, a finger adjacent to the finger inserted into the wearing space FS can be placed on the finger rest. In addition, an inertial sensor 71, a geomagnetic sensor 72, a vibration element 8, a communication unit 9, a control unit 10, a power supply 11, etc. are arranged inside the main body 2 (inside the outer casing 20).

[0060] The details of the touch sensor 5 and the button switch 6 will be described later.

[0061] The inertial sensor 71 includes an acceleration sensor for detecting the position and speed of the ring-type device 1 equipped with the inertial sensor 71, a gyro sensor (angular velocity sensor) for detecting the posture and orientation of the ring-type device 1, etc. The detection data of the earth's magnetic force from the geomagnetic sensor 72 is used to correct the detection data of the inertial sensor 71.

[0062] The vibration element 8 is used to generate vibration in the ring-type device 1 and provide the vibration as tactile information to the user's finger F. The communication unit 9 includes, for example, a wireless module, a wireless antenna, etc., and can communicate with an external device through wireless communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark).

[0063] Control unit 10 includes, for example, a CPU as a calculation processing unit, a ROM, a RAM, etc. as a storage unit for storing programs, calculation parameters, etc., and controls the overall operation of ring type device 1. Power supply 11 supplies power to each component of ring type device 1.

[0064] Overview of Information Processing Systems

[0065] Reference Figure 2A , Figure 2B and Figure 3 , an overview of the information processing system 100 in which the ring-type device 1 according to the present embodiment is used will be described.

[0066] Figure 2A , Figure 2B and Figure 3 The information processing system 100 shown in FIG. 1 is a system that provides a so-called MR (mixed reality) space to a user using an HMD (head mounted display) 101. The HMD 101 is equipped with a camera 113 for capturing an image of a space in front of a user wearing the HMD 101 and a display 114 for displaying a video image seen by the user wearing the HMD 101. The control unit 110 is equipped with, for example, a CPU as a calculation processing unit, a ROM, a RAM, etc. as a storage unit for storing programs, calculation parameters, etc., and controls the overall operation of the HMD 101. The display 114 displays a video image (in which an image of a non-entity virtual object or the like generated by signal processing in the HMD 101 is superimposed) on the real space captured by the camera 113.

[0067] The ring-type device 1 and the HMD 101 are connected to each other via wired or wireless communication through the communication unit 9 and the communication unit 109 , and can transmit and receive data with each other.

[0068] The user can use the ring-type device 1 to perform various input operations on a virtual object or the like displayed on the display 114. For example, various input operations can be performed by changing the orientation of the ring-type device 1, operating the touch sensor 5 or the button switch 6 provided on the operating portion of the ring-type device 1, or by combining these operations in various ways.

[0069] exist Figure 2A In the example shown, three virtual objects O1 to O3 are arranged side by side in front of the eyes of the user wearing the HMD 101. A virtual light beam L is projected on the display 114 from the ring-type device 1 worn on the user's finger in a manner extending forward in a direction corresponding to the orientation of the ring-type device 1. The virtual light beam L is a so-called laser pointer type user interface.

[0070] Figure 2BThe state when the user operates the ring-type device 1 and selects the virtual object O2 from the three virtual objects O1 to O3 is shown. The user can perform the operation of selecting the virtual object O2 by changing the position or orientation of the ring-type device 1 so that the virtual light beam L hits the virtual object O2 and, for example, tapping the touch sensor 5 of the operation part. By selecting the virtual object O2, various information displays related to the virtual object O2 and menu displays for performing various input operations on the virtual object O2 are displayed as a virtual object M next to the virtual object O2. Various input operations can also be performed on the virtual object M using the ring-type device 1.

[0071] In addition, in a system that can recognize a real three-dimensional structure from an image captured by the camera 113, a virtual input operation can be performed on the recognized three-dimensional structure using the ring-type device 1.

[0072] In addition, the speaker 115 outputs a sound corresponding to the operating state of the ring-type device 1 and the state in the MR space displayed on the display 114, and auditory information is provided to the user together with the visual information. In addition, the vibration element 8 generates vibrations corresponding to the operating state of the ring-type device 1 and the state in the MR space displayed on the display 114, and transmits the vibrations to the finger or hand wearing the ring-type device 1. That is, tactile information corresponding to the visual information and the auditory information is provided to the user.

[0073] Here, the above-mentioned information processing system 100 is a system using a so-called video see-through method, but the ring-type device 1 according to the present embodiment can also be used for a system using an optical see-through method. That is, the information processing system 100 is a system configured to project a real space directly to the user's eyes through a lens provided in the HMD 101 instead of an image displayed by the display 114, and to display a virtual object or the like on the lens. Alternatively, the ring-type device 1 according to the present embodiment can also be used for a system that projects a video onto the user's retina to allow the user to visually recognize a virtual object.

[0074] The above-mentioned information processing system 100 can also be used to display a VR (virtual reality) space generated only by signal processing in the HMD 101 on the display 114 without using the image captured by the camera 113. In other words, the information processing system 100 can be used as a system for providing a VR (virtual reality) space to the user, and various input operations can be performed in such a VR space using the ring-type device 1 of the present embodiment.

[0075] Details of the ring-shaped device (structure of the operating part)

[0076] The touch sensor 5 detects the contact of the finger F and sends an input signal to the control unit 10, and is configured to be able to send various types of input signals to the control unit 10 by changing the way the finger F contacts. Specifically, examples of input operations include: a tap operation, in which the finger F briefly contacts the touch sensor 5 in a tapping manner and then releases; and a swap operation, in which the finger F contacts the touch sensor 5 in a sliding manner, thereby changing the contact position of the finger F on the touch sensor 5. Through such various input operations, a virtual object selection operation, a scroll operation, etc. can be performed. In addition, an operation of maintaining a predetermined state only when the finger F touches the touch sensor 5 is feasible. For example, an operation of maintaining a state of emitting a virtual light beam L only when the finger F touches the touch sensor 5 and no longer emitting the virtual light beam L when the finger F is removed from the touch sensor 5 is feasible. Alternatively, an operation of maintaining a selection state of a virtual object only when the finger F touches the touch sensor 5 and releasing the selection state of the virtual object when the finger F is removed from the touch sensor 5 is feasible.

[0077] For example, when performing an alternative selection operation or a reverse selection operation, a pair of push button switches 6L and 6R may be used. Figure 2B As shown, in a state where the virtual object O2 is selected, when the button switch 6L is pressed, the selected object can be changed to the left virtual object O1, and when the button switch 6R is pressed, the selected object can be changed to the right virtual object O3.

[0078] Details of the ring-type device (how to wear it)

[0079] Figure 4A is a schematic diagram showing a first wearing mode which is an example of a wearing mode when the ring-type device 1 is used. Figure 4B is a schematic diagram showing the second wearing mode which is another example of the wearing mode when the ring-type device 1 is used. Figure 4C is a schematic diagram showing a third wearing mode which is an example of a wearing mode when the ring-type device 1 is not used. Note that the wearing mode shown here is only an example, and the wearing mode of the ring-type device 1 of the present embodiment is not limited to the following.

[0080] Figure 4A The first wearing mode shown is a wearing mode when the ring-type device 1 is worn on the index finger. That is, it is a wearing mode in which the index finger is inserted into the wearing space FS and various operations are performed with the thumb. In this wearing mode, the thumb can be placed on the first finger rest 223.

[0081] Figure 4BThe second wearing mode shown is a wearing mode when the ring-type device 1 is worn on the middle finger. That is, in this wearing mode, the middle finger is inserted into the wearing space FS, and various operations are performed mainly with the thumb. In this wearing mode, the thumb can be placed on the first finger rest 223, and the index finger can be placed on the second finger rest 224.

[0082] Figure 4C The third wearing mode shown is a wearing mode for a case where the ring-type device 1 is not used but is to be kept, for example. Figure 4C As shown, the third wearing mode is the gripping mode, in which Figure 4A and Figure 4B The wearing modes shown maintain the orientation of the ring-type device 1 differently. The ring-type device 1 is configured so that the volume of the main body 2 is relatively large compared to the first arm 3 and the second arm 4. In the third wearing mode, the first arm 3 and the second arm 4 are grasped in the palm. On the other hand, in the first wearing mode and the second wearing mode, a part of the main body 2 is grasped in the palm. That is, in the third wearing mode, the volume of the ring-type device 1 on the palm side is reduced compared to the first wearing mode and the second wearing mode, making it easier to grasp and hold the ring-type device 1, and preventing the ring-type device 1 from interfering with other tasks.

[0083] Details of the ring-type device (arm structure)

[0084] Will refer to FIG. 5A to FIG. 5C as well as Fig. 6A and Figure 6B The construction of the first arm 3 and the second arm 4 of the ring-type device 1 is described. FIG. 5A to FIG. 5C Schematic diagram showing changes in the postures of the first arm 3 and the second arm 4 due to the difference in thickness of the finger F. Here, description will be made on the case where the first arm 3 and the second arm 4 are worn on the finger F1 of the first thickness ( Figure 5B ), when worn on finger F2 having a second thickness greater than the first thickness ( Figure 5A ) and when worn on a finger F3 having a third thickness greater than the second thickness ( Figure 5C ) of a ring-shaped device 1. Fig. 6A 1 is a bottom view of the ring-type device 1 viewed in a direction opposite to the arrow A in FIG. 1 . Figure 6B The ring-type device 1 is a modified example in which the width of the first arm 3 is changed. Fig. 6A Same bottom view.

[0085] like Fig. 6AAs shown, the first arm 3 and the second arm 4 are arranged so that their positions in the insertion direction ID of the finger F relative to the wearing space FS overlap each other. In addition, the lengths of the first arm 3 and the second arm 4 from the main body 2 in the direction around the wearing space FS are lengths such that their end side areas interfere with each other according to the thickness of the finger F to be placed. That is, the end of one of the first arm 3 and the second arm 4 when closest to the inner surface 21 of the main body 2 is positioned closer to the rotation axis of the other arm than the end of the other arm when closest to the inner surface 21.

[0086] like Figure 1A As shown, when the device is worn on a finger F4 having a fourth thickness which is thicker than the third thickness, the first arm 3 and the second arm 4 are at a large angle relative to the body 2 and do not interfere with each other. FIG. 5A to FIG. 5C As shown, when the wearing space FS corresponding to the fingers F1 to F3 is formed, the areas on the tip side of the first arm 3 and the second arm 4 interfere with each other. Therefore, the first arm 3 and the second arm 4 cannot contact the fingers F1 to F3 at the same time, and one of the arms contacts the fingers F1 to F3, while the other arm applies force to the one arm to make it press against the fingers F1 to F3 (support it from the back). That is, the area including at least the tip of the other arm when it is closest to the inner surface 21 of the body 2 is positioned closer to the outside of the wearing space FS than the one arm when it is closest to the inner surface 21.

[0087] The wearing posture is necessarily formed such that the smaller the thickness of the finger F is, the larger the space between the finger F and the wearing space FS is, and the wider the gap between the placed finger F and the adjacent finger F is. In other words, there is a concern that the smaller the thickness of the finger F is, the easier it is for the wearing posture of the ring-type device 1 on the finger F to become unstable.

[0088] Here, in the ring-type device of the present embodiment, as described above, one arm that contacts the finger F is supported from behind by the other arm. In addition, the region where the other arm contacts one arm, that is, the region OR where one arm and the other arm overlap each other when viewed in a direction perpendicular to the rotation axis of one arm or the rotation axis of the other arm, is configured to become wider as the finger F becomes thinner. FIG. 5A to FIG. 5C As shown, the contact area between one arm and the other arm widens in the order of areas OR3, OR2, and OR1 from finger F3 to finger F1. By widening the contact area, the area on which the applied force received by one arm from the other arm acts widens, and the force of one arm holding the finger F between the one arm and the inner surface 21 of the body 2 increases, resulting in a stable wearing state.

[0089] With the above configuration, when the thickness of the finger F to be placed is thin, the contact area between the first arm 3 and the second arm 4 is expanded, making it possible to prevent the wearing posture of the ring-type device 1 on the finger F from becoming unstable.

[0090] In this way, the wearing space FS can be changed to correspond to the width of the fingers F1 to F4 of various sizes (diameters), and the holding force acting on the finger F can be changed according to the thickness of the finger F. In this way, even if the size of the inserted finger F is different, the main body 2, the first arm 3, and the second arm 4 can be stably wrapped around the periphery of the finger F. In other words, regardless of the size of the finger F inserted into the wearing space FS, the ring-type device 1 is worn and held on the user's finger F in a stable posture.

[0091] In the present embodiment, the first arm 3 is arranged inside the second arm 4 and directly contacts the finger F, while the second arm 4 supports the first arm 3 from behind. However, the opposite configuration may be used. That is, the second arm 4 may be arranged inside the first arm 3 and directly contacts the finger F, while the first arm 3 may support the second arm 4 from behind.

[0092] The applied force (spring constant of the torsion coil spring) applied to the first arm 3 and the second arm 4 is preferably set to a size that does not cause misalignment between the finger F and the ring-type device 1 for users with thin fingers F. For example, the spring constant of the torsion coil spring can be set by adjusting the number of turns so that an applied force of 10N*mm or more is generated. On the other hand, for users with thick fingers F, if the applied force is too strong, pain may occur during wearing, so it is preferable to set the applied force to a level that does not increase the load on the finger F. For example, the spring constant of the torsion coil spring can be set by adjusting the number of turns so that the applied force is suppressed to 45N*mm or less. Although it depends on the device configuration, it is preferable to set the spring constant to at least 15N*mm and not more than 30N*mm. The range of the upper and lower limits of such applied force can be found, for example, by experiment, and the spring constants of the torsion coil spring 32a and the torsion coil spring 42a can be appropriately set.

[0093] In addition, the applied force (spring constant of the torsion coil spring 32a) applied to the first arm 3 and the applied force (spring constant of the torsion coil spring 42a) applied to the second arm 4 can be set to the same level. However, this is not limited to this, for example, in the case where the arm on the inner side and the arm on the outer side relative to the wearing space FS are predetermined, the applied force acting on the inner arm and the applied force acting on the outer arm can be different to enhance the wearing stability.

[0094] For example, the arm on the outside of the first arm 3 and the second arm 4 relative to the wearing space FS can be made wider than the arm on the inside in the insertion direction ID, and the number of turns of the torsion coil spring can be relatively increased, thereby increasing the applied force compared to the arm on the inside. Alternatively, the inner diameter of the inner surface of the outer arm can be made larger than the inner diameter of the inner surface of the inner arm without making the spring constant different.

[0095] In the present embodiment, the wearing space FS is configured to have a width that can accommodate an imaginary circle with a predetermined diameter range (i.e., a finger with a thickness equivalent to the imaginary circle) when viewed in the insertion direction ID. Specifically, the width is the width that can accommodate an imaginary circle with a diameter of 12.8 mm (the thickness of the finger F1 is equivalent to this) to an imaginary circle with a diameter of 25.4 mm (the thickness of the finger F4 is equivalent to this), that is, a width of at least 12.8 mm and not more than 25.4 mm. Figure 1A As shown, the basis for the change in the size of the imaginary circle is the deepest part of the concave arc (concave curve) inner surface 21 of the body 2. That is, the imaginary circle of each size is configured to pass through the point of the deepest part, and the spatial area corresponding to the size of the imaginary circle is used as a basis for measuring the width of the wearing space FS.

[0096] like Figure 6B As shown, in the insertion direction ID of the finger F relative to the wearing space FS, the width of the inner arm contacting the finger F may be narrower than the width of the outer arm. Figure 4C As shown, it is feasible to hold the gripping mode of the ring-type device 1 by changing the orientation of the ring-type device 1. In this wearing state, the side of the finger F facing the arm is the inner side (palm side) of the finger F, which is the side that is concave when the joint of the finger F is bent. In the present embodiment, the width W3 in the insertion direction ID of the first arm 3 which is the inner arm in contact with the finger F is narrower than the width W4 in the same direction of the second arm 4 which is the outer arm away from the finger F, so that the finger F can be easily bent. In this way, it becomes easier to take the posture of gripping the finger to hold the ring-type device 1. For example, when other tasks are performed while holding the ring-type device 1, the operation is prevented from being hindered, and the efficiency of the operation can be improved. In addition, the procedures for wearing and taking off the ring-type device 1 can be reduced, so that the efficiency of a series of operations can be improved.

[0097] In addition, the first arm 3 and the second arm 4 are configured so that the width in the insertion direction ID gradually narrows toward the end. Here, in particular, the width in the insertion direction ID of the end surface of the arm entering the inner side of the wearing space FS is preferably 20 mm or less, or less than the width of the main body 2 in the insertion direction ID. More preferably, the width is 8 mm or less, which is suitable for accommodating the first arm 3 and the second arm 4 between the first joint and the second joint of the finger F. Alternatively, in the area where the first arm 3 and the second arm 4 overlap each other, the width of the inner arm in the insertion direction ID may fall within the above range.

[0098] Fig. 7A is a schematic diagram of the first arm 3, and Figure 7B It is along Fig. 7A2 is a cross-sectional view taken along the arrow C in FIG. Here, only the first arm 3 will be described, but the second arm 4 is configured in the same manner, so the description will be omitted.

[0099] The inner surface 31 is a portion of the first arm 3 that contacts the finger F, and preferably, the surface of the inner surface 31 is particularly smooth. Fig. 7A and Figure 7B As shown, the first arm 3 may be constructed with two members, namely, a first member 30a on the inner surface 31 side and a second member 30b on the opposite outer surface 34 side. In the case of such a configuration, when the first arm 3 is manufactured by combining a plurality of members, the parting line between the first member 30a and the second member 30b may be positioned away from the inner surface 31, and the inner surface 31 may be smoothly formed. In addition, the parting line between the first member 30a and the second member 30b is preferably positioned as close to the outer surface 34 as possible in order to more effectively prevent the finger F from being caught. The inner surface 31 is a gently smooth concave surface, which prevents the finger F from being caught when the finger F is inserted, and also makes cleaning easier.

[0100] In addition, if Fig. 7A As shown, the end surface 33 (first end surface) of the first arm 3 may be configured to have a tapered surface shape so as to prevent the finger F from being caught when the finger F and the ring-type device 1 rotate relative to each other. That is, the end surface 33 of the first arm 3 has an inner distance (first inner distance) Li from the rotation axis (first rotation axis) 32x of the first arm 3 to the end surface 33 on the inner surface (first inner surface) 31. In addition, the end surface 33 has an outer distance (first outer distance) Lo from the rotation axis 32x to the end surface 33 on the outer surface (first outer surface) 34. The end surface 33 is inclined relative to an imaginary plane vp perpendicular to the extension direction of the first arm 3 in such a manner that the inner distance Li is shorter than the outer distance Lo.

[0101] In addition, if Figure 7B The cross section (along Fig. 7A As shown in the cross section of the arrow C in FIG. 1 , the inner surface 31 is configured so that both sides in the insertion direction ID are tapered surfaces ts1 and ts2 symmetrically inclined relative to the insertion direction ID. With this configuration, the finger F is prevented from being caught on the inner surface 31, and the finger F is smoothly guided to be inserted into the wearing space FS and removed from the wearing space FS.

[0102] like Figure 8As shown, the lengths of the first arm 3 and the second arm 4 from the main body 2 are preferably set so that when the thickest finger F4 worn thereon is allowed to be inserted, the ring-type device 1 does not slip off the finger F4. For example, the gap Ws1 between the end surface 33 and the end surface 43 of each arm when the first arm 3 and the second arm 4 are opened to insert the thickest finger F4 can be set to half or less of the distance Ws2 corresponding to the maximum diameter of the thickest finger F4. In this way, the ring-type device 1 can be prevented from slipping off the finger when used by a user with a thick finger F.

[0103] like Fig. 9 As shown, preferably, when the first arm 3 and the second arm 4 are opened to the movable limit, the gap Ws3 between the end surface 33 and the end surface 43 of each arm is set to be slightly larger than the maximum diameter of the corresponding thickest finger F4. In the case of this configuration, when the ring-type device 1 is removed from the thickest finger F4, the ring-type device 1 can be removed in a direction perpendicular to the insertion direction ID.

[0104] In addition, in the present embodiment, the lengths of the first arm 3 and the second arm 4 from the main body 2 are substantially the same, but they may be different.

[0105] like Fig.10 As shown, for example, the length of the first arm 3 is made shorter than the length of the second arm 4, and the rotatable range (maximum opening angle) of the first arm 3 relative to the main body 2 is made larger than the rotatable range (maximum opening angle) of the second arm 4 relative to the main body 2. In this way, when the finger F is removed from the wearing space FS, the moving direction of the finger F can be guided to the side where the applied force is weak, and the second arm 4 can be controlled to close before the first arm 3. At this time, it is preferable to set a tapered surface on the outer surface side of the end of the second arm 4 that is closed first and comes to the inside relative to the wearing space FS. Due to the effect of the tapered surface, when the end of the second arm 4 collides with the end of the first arm 3, the second arm 4 can easily enter the inside.

[0106] like Fig.11 As shown, the inner surface 21 of the body 2 may be a concave surface in which a plurality of planes 21f1 and 21f2 are connected at gradually changing angles. In the above-described embodiment, the inner surface 21 of the body 2, the inner surface 31 of the first arm 3, and the inner surface 41 of the second arm 4 are all formed by concave curved surfaces having a curvature corresponding to the maximum diameter of the thickest finger F4, but the present invention is not limited to this configuration. Fig.11 As shown, the concave surface may be formed by planes 21f1 and 21f2 including tangent lines of an imaginary circle (imaginary cylindrical surface) corresponding to the maximum diameter of the thickest finger F4.

[0107] like Fig.12As shown, preferably, the center FC of the imaginary circle corresponding to the finger Fb of the smallest diameter accommodated in the wearing space FS is constructed to be located on the imaginary line vl passing through the rotation center of the first arm 3 and the rotation center of the second arm 4, or is located closer to the main body 2 than the imaginary line vl. In addition, a third finger rest 213 and a fourth finger rest 214 are preferably provided, and the fingers Fa and Fc on both sides of the finger Fb can be placed on the third finger rest 213 and the fourth finger rest 214, respectively, on the outside of the first arm 3 and the second arm 4. According to this construction, Figure 4C In the third wearing mode shown, the first arm 3 and the second arm 4 are prevented from interfering with the grip of the fingers.

[0108] like Fig.13 As shown, a limiting portion 29 is provided on the inner side of the outer casing 20 of the main body 2. The limiting portion 29 is provided so as to be able to contact the outer surface 34 of the rotation axis 32 around the first arm 3 so as to limit the maximum rotation angle (rotation range) of the first arm 3. The outer casing 20 is a member requiring strength in the device structure, and is configured so that the limiting portion 29 that limits the rotation of the first arm 3 is provided as a part of the outer casing 20. By improving the strength of the device and suppressing the occurrence of breakage during long-term use, the life of the device can be extended. This rotation limiting structure is also provided for the second arm 4. For the first arm 3 and the second arm 4, the rotation limiting range may be the same, or may be different.

[0109] Details of the ring-type device (configuration of the vibrating element)

[0110] Will refer to Figures 14 to 17 The configuration of the vibration element 8 in the ring-type device 1 of the present embodiment will be described in detail. Fig.14 1 is a schematic front view of the ring-type device 1 according to the present embodiment, showing the arrangement of the vibration element 8 . Fig.15A is a schematic front view of a ring-type device 1b according to a first comparative example. Fig. 15B is a schematic side view of a ring-type device 1c according to a second comparative example. Fig.16A : is a schematic cross-sectional view (a cross section perpendicular to the insertion direction ID) of the vibrating element 8 and its surroundings in the ring-type device 1 according to the present embodiment. Fig. 16B It is along Fig.16A A schematic cross-sectional view taken along the arrow D in FIG. Fig. 16C is a schematic partial cross-sectional view of the ring-type device 1 according to the present embodiment, showing a state when the power source 11 is expanded. Fig.17 1 is a side view of the ring-type device 1 according to the present embodiment, and shows the arrangement of the vibration element 8 .

[0111] The manner in which the vibration generated by the vibration element 8 is transmitted to the user may vary depending on the configuration of the vibration element 8 in the ring-type device 1. That is, depending on the position and orientation of the vibration element 8 in the ring-type device 1, the vibration of the vibration element 8 may not be well transmitted to the finger wearing the ring-type device 1, and the user may not have a desired sensory experience. In addition, when the ring-type device is configured so that it can be worn on a finger in various ways, the user's perception of the vibration may differ depending on the way it is worn (for example, when the finger wearing the device changes).

[0112] In addition, the vibration element 8 is a component that consumes a large amount of power among the components mounted on the ring-type device 1, and needs to vibrate efficiently with as little power as possible. It is difficult to install a large-capacity battery on the ring-type device 1, and it is necessary to transmit vibration efficiently with a small amount of power. On the other hand, if the vibration does not have a certain degree of amplitude, it may be difficult for the user to perceive it.

[0113] In addition, the configuration of the vibration element 8 must take into account the effect of vibration on the operation of other built-in devices. For example, the ring-type device 1 of this embodiment is equipped with an inertial sensor 71, and depending on the configuration of the vibration element 8, vibration may be transmitted to the inertial sensor 71, resulting in erroneous detection.

[0114] Vibration direction of the vibration element 8

[0115] In the ring type device 1 of the present embodiment, the vibration element 8 is arranged in a predetermined configuration so that the user wearing the ring type device 1 can more reliably sense the vibration of the vibration element 8. Specifically, the vibration element 8 is configured so that its vibration direction is toward the finger inserted into the wearing space FS.

[0116] As a configuration in which the vibration direction of the vibration element 8 is toward the finger inserted into the wearing space FS, as Fig.14 As shown, a configuration may be adopted in which an imaginary line VL passing through the vibration element 8 along the vibration axis VX of the vibration element 8 passes through the wearing space FS. That is, the imaginary line VL passes through the inner surface of an annular body surrounding the wearing space FS, and the outer surface opposite to the inner surface, the annular body being composed of the main body 2, the first arm 3 connected to one end of the main body 2, and the second arm 4 connected to the other end of the main body 2. In the present embodiment, the imaginary line VL passes through the inner surface 21 of the outer cover 20 of the main body 2 and the inner surface 31 of the first arm 3 as the inner surface of the annular body, and passes through the outer surface 22 of the outer cover 20 of the main body 2 and the outer surface opposite to the inner surface 31 of the first arm 3 as the outer surface of the annular body. One end of the vibration element 8 in the extending direction of the vibration axis VX is located on the side close to the inner surface 21 of the outer cover 20 of the main body 2 as the inner surface of the annular body, and the other end is located on the side close to the outer surface 22 of the outer cover 20 of the main body 2 as the outer surface of the annular body.

[0117] Fingers of various sizes can be placed in the wearing space FS. The size of the finger can vary greatly depending on the person or even the part of the finger. In order to accommodate different finger sizes, for example, if different components such as replacement components for each finger size are used to fill the gap between the device and the finger, the wearing operation becomes complicated and the number of components increases. In addition, for example, in a configuration in which an elastic component such as a rubber band is provided to follow the finger size (finger diameter), the fit (wearing stability) may be different depending on the finger size or the wearing position on the same finger. In other words, regardless of the difference in finger size, the ring-type device is required to be stable and operable during wearing. Therefore, it is preferable to configure the vibration element 8 so that the vibration of the vibration element 8 is reliably sensed by the user regardless of the size of the finger placed. Therefore, in the present embodiment, the imaginary line VL is configured to pass through the center F2C of the imaginary circular cross section corresponding to the finger F2 as the reference center position of the finger inserted into the wearing space FS. In the present embodiment, the center F2C is used as a center position that allows the user to sense the vibration of the vibration element 8 even when a finger F1 smaller than the finger F2 is placed, or when a finger F3 or F4 larger than the finger F2 is placed.

[0118] The reference center position of the wearing space FS for determining the vibration direction of the vibration element 8 is not limited to the above-mentioned center F2C, and can be appropriately determined according to the configuration of the device. For example, the center position of an imaginary circular cross section corresponding to an average size of a finger within the range of finger sizes that can be inserted into the wearing space FS can be used as the reference center position for determining the vibration direction of the vibration element 8. Alternatively, for example, the center of curvature of the concave arc surface constituting the inner surface 21 can be used as the reference center position.

[0119] In addition, it is preferable to arrange the vibration element 8 so that the above-mentioned imaginary line VL passes through the vicinity of the deepest part of the concave inner surface 21. The deepest part of the inner surface 21 may be the part where the fingers F1 to F4 of all sizes come into contact with the outer cover 20, such as Figure 1A By configuring the vibration of the vibration element 8 to be directly transmitted to such a portion, the user can easily sense the vibration of the vibration element 8 regardless of the size of the finger inserted into the wearing space FS.

[0120] Here, in the present embodiment, the vibration element 8 is a so-called linear vibration actuator. That is, the vibration element 8 is equipped with a movable part and a coil, the movable part is equipped with a magnet and supported by a shaft and a spring in a manner that it can reciprocate in a predetermined axial direction, and current can be applied to the coil from the outside. The movable part is integrally provided with a counterweight, and due to the excitation of the coil by the application of current and the magnetic force of the magnet arranged in the movable part, the movable part overcomes the applied force of the spring and reciprocates along the shaft in a predetermined axial direction (vibration axis direction). The reciprocating motion of the movable part generates vibrations in a predetermined vibration direction in the vibration element 8. In the vibration element 8 of the present embodiment, for example, an axis parallel to the axial direction of the shaft and passing through the center of the movable part can be set as the vibration axis VX, and the direction along the vibration axis VX can be set as the vibration direction of the vibration element 8.

[0121] The ring-type device 1 of this embodiment can be used in a wearing mode in which it is held between the finger inserted into the wearing space FS and another finger, such as FIG. 4A to FIG. 4C As shown. Therefore, by generating vibrations of the vibration element 8 along the finger and the arrangement of the fingers touching the ring-type device 1 (particularly the outer case 20), the vibrations can be more easily felt by the user. Therefore, for example, preferably, the vibration element 8 is configured so that the above-mentioned imaginary line VL passes through at least one of the first finger rest 223 and the second finger rest 224 of the outer case 20.

[0122] In this embodiment, if Fig.14 As shown, the vibration element 8 (or the second finger rest 224) is configured so that the imaginary line VL passes through the second finger rest 224. Therefore, the vibration element 8 can be located between the finger F2 inserted into the wearing space FS and the finger Fn placed on the second finger rest 224, and the vibration can be efficiently and effectively transmitted to each of the finger F2 and the finger Fn.

[0123] More preferably, the vibration element 8 is configured so that the imaginary line VL passes through an area of ​​the inner surface 21 that is particularly in contact with the finger inserted into the wearing space FS and an area of ​​the second finger rest 224 that is particularly in contact with the finger placed on the second finger rest 224. The concave shape of the inner surface 21 and the peripheral shape of the finger inserted into the wearing space FS generally do not completely match, and the periphery of the finger does not necessarily contact the entire area of ​​the inner surface 21. Similarly, the concave shape of the second finger rest 224 and the peripheral shape of the finger placed on the second finger rest 224 generally do not completely match, and the periphery of the finger does not necessarily contact the entire area of ​​the second finger rest 224. Therefore, for example, by configuring the vibration element 8 so that the imaginary line VL passes through the above-mentioned area of ​​the inner surface 21 and passes through the center of the finger inserted into the wearing space FS, vibration can be efficiently and effectively transmitted to the finger inserted into the wearing space FS. Similarly, by configuring the vibration element 8 so that the imaginary line VL passes through the above-mentioned area of ​​the second finger rest 224 and passes through the center of the finger placed on the second finger rest 224, vibration can be efficiently and effectively transmitted to the finger placed on the second finger rest 224.

[0124] In addition to the first finger rest 223 and the second finger rest 224, the outer surface 22 of the outer cover 20 as a contact portion that contacts a finger other than the finger inserted into the wearing space FS is also provided with a button switch 6 and a touch sensor 5 as operating members. Therefore, for example, in a ring-type device as a modified form of the present embodiment, the vibration element 8 may be configured so that the above-mentioned imaginary line VL passes through the button switch 6 and the touch sensor 5. In addition, if there is a concern that an erroneous operation may occur due to the vibration of the vibration element 8, the touch sensor 5 may be arranged at a position other than the above-mentioned imaginary line VL passing through the vibration element 8. In the present embodiment, as described later, the touch sensor 5 is arranged at a predetermined distance from the vibration element 8 in the circumferential direction around the center F2C of the imaginary circle corresponding to the finger F2 (as the center of the wearing space FS).

[0125] according to Fig.15A The ring-type device 1b of the first comparative example shown has a configuration of the vibration element 8 that is different from that of the ring-type device 1 according to the present embodiment. Specifically, in the ring-type device 1b, the vibration axis VX of the vibration element 8 is perpendicular to the vibration axis VX of the vibration element 8 in the ring-type device 1, and is perpendicular to the insertion direction ID of the finger into the wearing space FS. Therefore, in the first comparative example, the imaginary line VL passing through the vibration element 8 along the vibration axis VX does not pass through the wearing space FS, and there is a concern that the vibration of the vibration element 8 is not sufficiently transmitted to the finger wearing the ring-type device 1b.

[0126] In addition, in the first comparative example, the vibration direction of the vibration element 8 is along the circumferential direction around the finger, so there is a concern that the vibration of the vibration element 8 acts to cause the ring-type device 1b and the finger inserted into the wearing space FS to move relative to each other in the circumferential direction. In other words, there is a concern that the vibration of the vibration element 8 will cause the ring-type device 1b to rotate relative to the finger (the wearing position of the ring-type device 1b may shift in the direction around the outer circumference of the finger).

[0127] Fig. 15B The ring-type device 1c according to the second comparative example shown is different from the ring-type device 1 according to the present embodiment in the configuration of the vibration element 8, as in the ring-type device 1b according to the first comparative example. Specifically, in the ring-type device 1c, the vibration axis VX of the vibration element 8 is perpendicular to the vibration axis VX of the vibration element 8 in the ring-type device 1 according to the present embodiment, and is along the insertion direction ID of the finger entering relative to the wearing space FS. Therefore, in the second comparative example, the imaginary line VL passing through the vibration element 8 along the vibration axis VX does not pass through the wearing space FS, and there is a concern that the vibration of the vibration element 8 is not sufficiently transmitted to the finger wearing the ring-type device 1c.

[0128] In addition, in the second comparative example, since the vibration direction of the vibration element 8 is along the insertion direction ID of the finger into the wearing space FS, there is a concern that the vibration of the vibration element 8 acts to cause the ring-type device 1b and the finger inserted into the wearing space FS to move relative to each other in the insertion direction ID. In other words, there is a concern that the vibration of the vibration element 8 may cause the ring-type device 1c to move relative to the finger in the insertion direction ID (the wearing position of the ring-type device 1b relative to the finger may shift in the insertion direction ID).

[0129] Compared with the first comparative example and the second comparative example, the ring-type device 1 according to the present embodiment can effectively transmit the vibration of the vibration element 8 to the finger wearing the ring-type device 1. In addition, the ring-type device 1 according to the present embodiment can obtain a stable wearing state without the concern that the vibration of the vibration element 8 may affect the wearing state of the ring-type device 1 on the finger as in the first comparative example and the second comparative example.

[0130] Arrangement of the vibration element 8 in the outer casing 20

[0131] The vibration element 8 is preferably arranged near a portion of the outer cover 20 forming the outer surface 22 in a manner of contacting the portion, on which the first finger rest 223, the second finger rest 224, the button switch 6, and the touch sensor 5 are arranged. By making the vibration strongly transmitted to the outer side portion of the outer cover 20, the vibration is easily transmitted not only to the finger inserted into the wearing space FS but also to other fingers, making it easier for the user to feel the vibration.

[0132] like Fig.16A and Fig. 16B As shown, the outer casing 20 includes an inner outer casing 210 as a first shell and an outer outer casing 220 as a second shell. The inner outer casing 210 has an inner surface 21 that forms a wearing space FS. The outer outer casing 220 has an outer surface 22, on which a first finger rest 223, a second finger rest 224, a button switch 6, a touch sensor 5, etc. are arranged. The inner outer casing 210 and the outer outer casing 220 are joined to each other by screws or the like to form a roughly arc-shaped storage space (internal space of the outer casing 20) therebetween for accommodating built-in devices such as an inertial sensor 71, a geomagnetic sensor 72, a vibration element 8, a communication unit 9, a control unit 10, and a power supply 11.

[0133] The vibration element 8 is mounted on the mounting portion 208, and the mounting portion 208 is provided on the inner surface of the outer outer casing 220 forming the above-mentioned storage space of the outer casing 20. Since the vibration of the vibration element 8 is directly transmitted to the outer outer casing 220, the vibration is easily transmitted to the finger touching the first finger rest 223, the second finger rest 224, the button switch 6, the touch sensor 5, etc. provided on the outer outer casing 220.

[0134] Meanwhile, the inner surface of the inner outer casing 210 forming the above-mentioned storage space of the outer casing 20 is provided with a mounting portion 201 and a mounting portion 211, on which the control board 111 having a control IC as the control unit 10 mounted thereon is mounted, and on which the communication unit 9 and the power supply 11 are mounted. Although not shown in the figure, the inner surface of the inner outer casing 210 is also provided with the following mounting portions: a board is mounted thereon, on which the inertial sensor 71 and the geomagnetic sensor 72 are mounted.

[0135] In other words, the vibration element 8 is configured in the above-mentioned storage space of the outer casing 20 separately from other built-in devices (installed away from the board on which other built-in devices are installed). The operation of the vibration element 8 (applying current to the coil) is controlled by a control signal from the control unit 10, but the vibration element 8 is arranged separately from the board 111 on which the control unit 10 is installed, and is connected to the board 111 through a flexible cable 18. The vibration element 8 is also separated from other boards installed on the inner outer casing 210 of the outer casing 20. In this way, the vibration of the vibration element 8 is prevented from being directly transmitted to various devices arranged on the inner outer casing 210.

[0136] In addition, when it is important for the vibration of the vibration element 8 to be transmitted to the finger inserted into the wearing space FS, for example, the mounting portion 208 can be extended to a position close to the inner exterior 210, and the vibration element 8 can be configured to be closer to the inner surface 21 rather than the outer surface 22.

[0137] In addition, the mounting portion 211 on which the communication unit 9 and the power supply 11 are mounted is configured to form a gap space ES as a shared space for the communication unit 9 and the power supply 11. The communication unit 9 includes a wireless module 90, a wireless antenna 91, and a wireless board 92 on which the wireless module and the wireless antenna are mounted. In addition, in the present embodiment, the power supply 11 is a lithium-ion battery, which is prone to expansion under abnormally high temperature conditions, and is provided with, for example, an exhaust valve for exhausting gas when the battery expands. In order to ensure sensitivity, it is desirable to avoid placing obstacles that may interfere with the reception of radio waves around the wireless antenna 91 as much as possible, and in particular, it is desirable to exclude conductors, and a space for ensuring sensitivity is usually provided around the wireless antenna 91. In addition, the power supply 11, which is a lithium-ion battery, requires space around it to allow expansion under the above-mentioned abnormal conditions.

[0138] like Fig.16A As shown, the mounting portion 211 is configured to support the wireless board 92 and the power supply 11 so that a gap space ES is formed between the wireless board 92 and the power supply 11 of the communication unit 9. Fig. 16C As shown, the gap space ES provides a space that allows the above-mentioned expansion of the power source 11, and also provides a space around the wireless antenna 91 to ensure sensitivity. That is, the gap space ES is a space shared by the communication unit 9 and the power source 11, and by sharing the space required by the communication unit 9 and the power source 11, the space of the exterior 20 can be reduced and the degree of freedom of layout of the internal space of the exterior 20 can be improved.

[0139] In addition, if Fig.14 and Fig.17 As shown, the vibration element 8 is configured so that its longitudinal direction is aligned with the insertion direction ID of the finger F. The vibration element 8 provided in the ring-type device 1 of the present embodiment has a substantially rectangular outer shape, and by aligning its longitudinal direction with the insertion direction ID of the finger F, it can be configured so as not to occupy the circumferential space in the substantially arc-shaped space inside the outer case 20. Therefore, the degree of design freedom can be increased in the shape design of the outer case 20 that follows the outer circumference of the finger.

[0140] It should be noted that if Fig.17 As shown, in the present embodiment, the vibration element 8 is configured so that the extension direction of the vibration axis VX of the vibration element 8 is perpendicular to the insertion direction ID of the finger into the wearing space FS, but it does not necessarily have to be perpendicular. In other words, it can be an intersecting direction with a slight angle relative to the vertical direction, as long as the vibration of the vibration element 8 can be sufficiently transmitted to the finger inserted into the wearing space FS or the finger placed on the first finger rest 223 and the second finger rest 224, etc.

[0141] The configuration relationship between the vibration element 8 and other built-in devices, etc.

[0142] like Fig.14 and Fig.16A As shown, in the ring-type device 1 of the present embodiment, in addition to the vibration element 8, built-in devices such as the communication unit 9, the control unit 10, the power supply 11, the inertial sensor 71, and the geomagnetic sensor 72 are attached to the inner exterior 210. In addition, the vibration element 8 and the other built-in devices are arranged inside the exterior 20 at a distance from each other in the circumferential direction around the center F2C of the imaginary circle corresponding to the finger F2 (which is the center of the wearing space FS).

[0143] like Fig.14 As shown, in the configuration structure observed along the insertion direction ID of the finger, the axis CX is an axis parallel to an imaginary line passing through the rotation center of the first arm 3 (rotation axis 32x) and the rotation center of the second arm 4 (rotation axis 42x) and passing through the center F2C as the reference center position. In addition, the axis CY is an axis perpendicular to the axis CX and passing through the center F2C. In the coordinate system formed by the axes CX and CY, the inertial sensor 71, the geomagnetic sensor 72 and the touch sensor 5 are located in the first quadrant, the vibration element 8, the communication unit 9 and the power supply 11 are located in the second quadrant, and the control unit 10 is positioned to span the first quadrant and the second quadrant. The communication unit 9, the control unit 10 and the power supply 11 included in the second quadrant same as the vibration element 8 are configured in a circumferential positional relationship around the center F2C at a position that does not overlap with the imaginary line VL passing through the vibration element 8 (a position offset from the vibration element 8 when observed in the vibration direction of the vibration element 8).

[0144] It is to be noted that the area where the first arm 3 and the second arm 4 are opened and closed is around the boundary between the third quadrant and the fourth quadrant in the coordinate system formed by the axes CX and CY, and is an area opposite to the area where various built-in devices including the vibration element 8 are arranged across the axis CX. That is, the first arm 3 and the second arm 4 hold the finger from the side opposite to the vibration element 8, and push the finger from the third and fourth quadrants toward the first and second quadrants, that is, toward the body 2, so that the vibration of the vibration element 8 is easily transmitted to the finger.

[0145] As described above, the vibration element 8 in the present embodiment is configured to operate by passing an electric current through a coil, and there is a concern that the magnetic force and magnetic field generated by the electric current passing through the coil may affect the operation of other built-in devices. For example, there is a concern that the magnetic force and magnetic field generated by the vibration element 8 may be detected as noise by the inertial sensor 71 and the geomagnetic sensor 72. In addition, the communication unit 9 includes a wireless module 90 and a wireless antenna 91, but the magnetic force and magnetic field generated by the vibration element 8 may also become noise in the wireless antenna 91, and there is a concern that the metal material constituting the vibration element 8 may affect the sensitivity of the wireless antenna 91. In addition, as described above, there is a concern that the vibration of the vibration element 8 may cause erroneous operation of the touch sensor 5.

[0146] The geomagnetic sensor 72 is arranged at a certain distance from the vibration element 8 in a manner forming an angle of at least 60 degrees or greater, preferably 90 degrees or greater, in the circumferential direction around the center F2C. The separation distance between the geomagnetic sensor 72 and the vibration element 8 can be determined, for example, by the shortest distance between the geomagnetic sensor 72 and the vibration element 8 in the circumferential direction around the center F2C. For example, an imaginary line passing through the portion of the geomagnetic sensor 72 that is closest to the vibration element 8 in the circumferential direction and the center F2C is defined as L72. In addition, an imaginary line passing through the portion of the vibration element 8 that is closest to the geomagnetic sensor 72 in the circumferential direction and the center F2C is defined as L8a. The geomagnetic sensor 72 and the vibration element 8 can be arranged so that the angle R1 formed by the imaginary line L72 and the imaginary line L8a around the center F2C falls within the above-mentioned angle range.

[0147] Similar to the geomagnetic sensor 72, the inertial sensor 71 is arranged at a certain distance from the vibration element 8 in a manner forming an angle of at least 60 degrees or greater, preferably 90 degrees or greater, in the circumferential direction around the center F2C. Similar to the geomagnetic sensor 72, the separation distance between the inertial sensor 71 and the vibration element 8 can be determined by the shortest distance between the inertial sensor 71 and the vibration element 8 in the circumferential direction around the center F2C. For example, an imaginary line passing through the portion of the inertial sensor 71 closest to the vibration element 8 in the circumferential direction and the center F2C is defined as L71. In addition, an imaginary line passing through the portion of the vibration element 8 closest to the inertial sensor 71 in the circumferential direction and the center F2C is defined as L8a. The inertial sensor 71 and the vibration element 8 can be arranged so that the angle R2 formed by the imaginary line L71 and the imaginary line L8a around the center F2C falls within the above-mentioned angle range.

[0148] The communication unit 9 is arranged so that the wireless antenna 91 is separated from the vibration element 8 by a certain distance in a circumferential direction around the center F2C in a manner forming an angle of at least 30 degrees or more, preferably 90 degrees or more. The separation distance between the wireless antenna 91 and the vibration element 8 can be determined, for example, by the shortest distance between the wireless antenna 91 and the vibration element 8 in the circumferential direction around the center F2C. For example, an imaginary line passing through the portion of the wireless antenna 91 closest to the vibration element 8 in the circumferential direction and the center F2C is defined as L91. In addition, an imaginary line passing through the portion of the vibration element 8 closest to the wireless antenna 91 in the circumferential direction and the center F2C is defined as L8b. The wireless antenna 91 (communication unit 9) and the vibration element 8 can be arranged so that the angle R3 formed by the imaginary line L91 and the imaginary line L8b around the center F2C falls within the above-mentioned angle range.

[0149] The touch sensor 5 is arranged at a certain distance from the vibration element 8 in a manner forming an angle of at least 30 degrees or more, preferably 90 degrees or more, in the circumferential direction around the center F2C. The separation distance between the touch sensor 5 and the vibration element 8 can be determined, for example, by the shortest distance between the touch sensor 5 and the vibration element 8 in the circumferential direction around the center F2C. For example, an imaginary line passing through the portion of the touch sensor 5 closest to the vibration element 8 in the circumferential direction and the center F2C is defined as L5. In addition, an imaginary line passing through the portion of the vibration element 8 closest to the touch sensor 5 in the circumferential direction and the center F2C is defined as L8a. The touch sensor 5 and the vibration element 8 can be arranged so that the angle R4 formed by the imaginary line L5 and the imaginary line L8a around the center F2C falls within the above-mentioned angle range.

[0150] Here, the center position of the wearing space FS for determining the circumferential separation distance between the vibration element 8 and other built-in devices, the touch sensor 5, etc. is not limited to the above-mentioned center F2C, and can be appropriately determined according to the configuration of the device. For example, the center position of an imaginary circular cross section corresponding to a finger having an average size in the size range of fingers that can be inserted into the wearing space FS can be used as a reference. Alternatively, for example, the center of curvature of the concave arc surface constituting the inner surface 21 can be used as a reference.

[0151] In addition, in the present embodiment, an example has been described in which a so-called linear vibration actuator is used as the vibration element 8, but other vibration actuators may be used as the vibration element 8. For example, a vibration actuator using a piezoelectric element or a vibration actuator using an eccentric motor may be used.

[0152] Details of the ring-shaped device (structure around the operating part)

[0153] Will refer to Figures 18 to 25B A configuration for improving operability in the ring-type device 1 of the present embodiment will be described.

[0154] Fig.18 1 is a top view showing the configuration of the operating surface of the ring-type device 1. Fig.18 As shown, the ring-type device 1 of the present embodiment has an operation surface located on the outer surface 22 of the outer casing 20 of the main body 2, and the operation surface is provided with a touch sensor 5 and button switches 6R and 6L as an operation portion. It is expected that the ring-type device 1 is used in such a manner that the user performs various input operations without looking at the hand wearing the ring-type device 1. That is, the user grasps and recognizes the touch sensor 5 and the button switches 6R and 6L by relying on the feeling of the fingers touching the operation surface, and performs the desired input operation. Therefore, the ring-type device 1 needs to be able to reliably grasp the positions of the touch sensor 5 and the button switches 6R and 6L without looking at the operation surface, and to be able to smoothly operate the touch sensor 5 and the button switches 6R and 6L without erroneous operation.

[0155] Here, the touch sensor 5 and the button switches 6R and 6L on the operation surface are configured so that the touch sensor 5 is configured on the wrist side of the hand wearing the ring-type device 1 and the button switches 6R and 6L are configured on the fingertip side, as shown in FIG. FIG. 4A to FIG. 4C That is, the touch sensor 5 is arranged on the front side along the circumferential direction around the finger insertion direction relative to the finger inserted into the wearing space FS, and the button switches 6R and 6L are arranged on the rear side. In the generally assumed operation mode, a finger other than the thumb (usually the index finger or the middle finger) is inserted into the wearing space FS, and the touch sensor 5 and the button switches 6R and 6L are operated by the thumb extending from the front side to the rear side of the touch sensor 5. It should be noted that although FIG. 4A to FIG. 4C A case where the ring-type device 1 is worn on the right hand is shown, but the ring-type device 1 may be worn on the left hand.

[0156] The first finger rest 223 is a finger rest (first recess) arranged on the front side of the outer casing 20 of the main body 2. For example, when the touch sensor 5 and the button switches 6R and 6L are not operated, the thumb can be placed on the first finger rest 223. The second finger rest 224 is a finger rest (second recess) arranged on the rear side of the outer casing 20 of the main body 2. For example, Figure 4B As shown, in the wearing mode in which the middle finger is inserted into the wearing space FS, the index finger can be placed on the second finger rest 224. This allows the ring-type device 1 to be held in a state in which a part of the ring-type device 1 is wrapped in the palm and the index finger presses the main body 2, thereby stabilizing the wearing posture of the ring-type device 1. In addition, the first finger rest 223 and the second finger rest 224 provide a place for the fingers to retreat when not operating, which prevents the fingers from accidentally touching the operating part, thereby preventing erroneous operation.

[0157] In addition, in the ring-shaped device 1 of this embodiment, Fig.18 The width Wd of the main body 2 shown (the width of the main body 2 in the insertion direction ID of the finger into the wearing space FS) is set to about 25.0 mm. This setting corresponds to the joint spacing of the finger inserted into the wearing space FS or the width of the thumb operating the touch sensor 5 and the button switches 6R and 6L.

[0158] In the ring-type device 1 of the present embodiment, the touch sensor 5 and the button switches 6R and 6L are constructed to have a predetermined size, shape and configuration, and are provided with a first boundary identification rib 25 and a second boundary identification rib 26 to be described later, on the premise that the device is operated by the thumb. Since the thumb is the widest finger on a human hand, the touch sensor 5 and the button switches 6R and 6L as the operating portion need to be easily pressed separately even if a sufficient size cannot be provided to them.

[0159] Boundary Identification Rib

[0160] like Fig.18 As shown in the other figures, the ring-type device 1 of the present embodiment has a first boundary identification rib 25 and a second boundary identification rib 26 as a configuration that allows the user to identify the difference and configuration of the touch sensor 5 and the button switches 6R and 6L only by the feeling of touching the operation surface with a finger. The first boundary identification rib 25 as the first rib and the second boundary identification rib 26 as the second rib are configured as part of the exterior 20. In addition, the shape and configuration of the touch sensor 5 and the button switches 6R and 6L as the operation portion are also configured to be suitable for operation only by the tactile sense of the finger.

[0161] The first boundary identification rib 25 is an annular rib configured to surround the outer circumference of the touch sensor 5. The first boundary identification rib 25 allows the user to recognize that the touch sensor 5 is located inside by making the finger feel the annular convex shape. In the present embodiment, the touch sensor 5 has a shape that protrudes higher than the first boundary identification rib 25. Therefore, the user can recognize that the convex-shaped portion that protrudes more from the annular convex shape is the touch sensor 5 by feeling the convex-shaped portion inside the annular convex shape with his / her finger.

[0162] In addition, a portion of the annular first boundary identification rib 25 is arranged between the touch sensor 5 and the button switches 6R and 6L. Therefore, the positional relationship between the first boundary identification rib 25 and the second boundary identification rib 26 described later allows the user to recognize the boundary between the touch sensor 5 as the first operating portion and the button switches 6R and 6L as the second operating portion.

[0163] The second boundary identification rib 26 is provided to extend along the circumferential direction between the button switches 6R and 6L arranged in the insertion direction ID of the finger into the wearing space FS of the ring-type device 1 on the outer surface 22 of the outer casing 20 of the main body 2. The second boundary identification rib 26 protrudes higher than the upper surface of the button switches 6R and 6L. Therefore, by touching the raised shape extending along the circumference (around the insertion direction of the finger) of the finger inserted into the wearing space FS with a finger, the user can recognize that the low parts adjacent to both sides of the raised shape in the insertion direction ID of the finger are the button switches 6R and 6L. That is, the second boundary identification rib 26 allows the user to recognize the boundary between the button switch 6R as the first operating part and the button switch 6L as the second operating part.

[0164] In addition, in the present embodiment, the first boundary identification rib 25 is arranged on the front side of the second boundary identification rib 26 in the circumferential direction of the finger, and the pair of push button switches 6R and 6L are arranged symmetrically with respect to the second boundary identification rib 26 in the finger insertion direction ID. It can be said that these configurations arranged around the second boundary identification rib 26 have a function of giving certainty that the convex shape extending in the circumferential direction that the user feels with the finger is the second boundary identification rib 26.

[0165] That is, the annular convex shape of the first boundary identification rib 25 is a characteristic shape that is easily recognized by touching with a finger alone, and is a shape that is easily recognized by the user. By making the user feel with his / her finger that the convex shape extending in the circumferential direction exists on the circumferential rear side of the finger of the annular convex shape, the user can confidently recognize that the convex shape in the circumferential direction is the second boundary identification rib 26.

[0166] Furthermore, by making the user feel that the convex shape extending in the circumferential direction of the finger is symmetrical on both sides of the finger insertion direction ID, the user can confidently recognize that the convex shape in the circumferential direction is the second boundary identification rib 26. Furthermore, the user can confidently recognize that the right side of the symmetrical shape of the convex shape in the circumferential direction on both sides of the finger insertion direction ID is the button switch 6R, and the left side is the button switch 6L.

[0167] Dimensional relationship etc. of the first boundary recognition rib 25

[0168] Fig.19 It is along Fig.18 The schematic cross-sectional view taken along the arrow E in FIG. 1 shows the height relationship among the touch sensor 5, the button switches 6R and 6L, the first boundary identification rib 25, etc. Fig.19As shown, the height H5 of the touch sensor 5 is higher than the height H25 of the first boundary identification rib 25. The height H6 of the button switches 6L and 6R is equal to or higher than the height H22 of the outer surface 22 of the outer casing 20 of the main body 2. The height H25 of the first boundary identification rib 25 is equal to or higher than the height H6 of the button switches 6L and 6R. In other words, the heights of the outer surface 22 of the outer casing 20 of the main body 2, the touch sensor 5, the button switches 6R and 6L, and the first boundary identification rib 25 are configured to satisfy the relationship H22≤H6≤H25<H5.

[0169] Here, in the present embodiment, the height difference (H25-H6) of the first boundary identification rib 25 relative to the button switches 6L and 6R is configured to be 0.3 mm or greater. In addition, in the present embodiment, the width W25 of the first boundary identification rib 25 (the difference between the inner diameter and the outer diameter of the first boundary identification rib 25) is configured to be 1.5 mm or greater.

[0170] The height H25 and the width W25 of the first boundary identification rib 25 are set from the perspective of preventing erroneous operation during blind operation. If the height H25 is too low or the width W25 is too narrow, it may be difficult to identify the first boundary identification rib 25. On the contrary, if the height H25 is too high or the width W25 is too wide, the operation of the touch sensor 5 may be hindered. The numerical range of each dimension described above is merely an example and may be appropriately set to a suitable numerical value from the perspective of operability according to the configuration of the device.

[0171] The first boundary identification rib 25 is disposed between the button switches 6R and 6L and the touch sensor 5 , thereby preventing the touch sensor 5 from being unintentionally operated when the button switches 6R and 6L, which are push buttons, are pressed.

[0172] The touch sensor 5 is a so-called optical pointing device, and includes an optical sensor unit 5c having a detection window at the center of a circular upper surface 5b of a button portion 5a. By moving a finger on the optical sensor unit 5c (moving the finger in a plane), a pointing operation, a flicking operation, etc. can be performed. It is to be noted that the touch sensor 5 is not limited to an optical pointing device, and may be, for example, a capacitive pointing device.

[0173] The touch sensor 5 is also configured so that the button 5a can move up and down, and the input operation of pressing the circular upper surface 5b of the button 5a is also feasible. That is, the button 5a is arranged to be movable so that the amount of depression relative to the first boundary identification rib 25 around its periphery can be changed, and the input state can be generated by pressing the circular upper surface 5b to be depressed inside the annular first boundary identification rib 25. The button 5a is applied by a force applying unit such as a spring (not shown) so as to be positioned at a height (original position) protruding from the first boundary identification rib 25 unless a specific external force is applied. The user can perform an input operation by pressing the circular upper surface 5b of the button 5a by overcoming the applied force of the force applying unit. When the finger is released and the pressed state (input state) of the button 5a is released, the applied force of the force applying unit causes the button 5a to return to the height (original position) protruding from the first boundary identification rib 25.

[0174] Here, preferably, the height of the circular upper surface 5b of the button portion 5a for generating the input state by the pressing operation is lower than the height of the first boundary identification rib 25. In this way, the button portion 5a can be configured so that the button portion 5a does not easily enter the input state even if the finger touches the button portion 5a while checking the first boundary identification rib 25 with the finger. In other words, the erroneous operation of the button portion 5a being erroneously placed in the input state can be suppressed.

[0175] In addition, an annular surface area of ​​the circular upper surface 5b around the periphery of the optical sensor unit 5c and an inclined area 25b extending from the base to the top 25a of the first boundary identification rib 25 are arranged between the top 25a of the first boundary identification rib 25 and the optical sensor unit 5c. In this way, a predetermined distance is ensured between the top 25a of the first boundary identification rib 25 and the optical sensor unit 5c. In this way, the occurrence of a false operation (an operation of a finger that checks the first boundary identification rib 25 by touching is detected as an input to the optical sensor unit 5c) can also be suppressed.

[0176] The outer periphery of the circular upper surface 5b of the button portion 5a is configured to have an inclined surface 5d whose diameter is expanded in a conical manner, and a distance is also provided between the top 25a of the first boundary identification rib 25 and the circular upper surface 5b. In this way, it is possible to prevent the movement of the finger that checks the feeling of the first boundary identification rib 25 from causing the operation of pressing the button portion 5a of the touch sensor 5. In other words, the occurrence of an erroneous operation can be suppressed.

[0177] The dimensional relationship and the like of the second boundary recognition rib 26

[0178] Fig. 20A and Fig. 20B It is along Fig.18 A schematic cross-sectional view taken along the arrow F in FIG. Fig. 20A and Fig. 20BAs shown, the second boundary identification rib 26 protrudes outward (upward) from the upper surface of each button switch 6R and 6L, and in the present embodiment, the protrusion height H26 is configured to be in the range of at least 0.3 mm and not more than 1.0 mm. In addition, in the present embodiment, the width (width in the finger insertion direction ID) W26 of the second boundary identification rib 26 between the button switches 6R and 6L is configured to be in the range of at least 1.0 mm and not more than 2.5 mm.

[0179] The protruding height H26 and width W26 of the second boundary identification rib 26 are set from the perspective of preventing erroneous operation during blind operation. If the protruding height H26 is too low or the width W26 is too narrow, it may be difficult to identify the second boundary identification rib 26. On the contrary, if the protruding height H26 is too high or the width W26 is too wide, the pressing operation of the button switches 6R and 6L may be hindered. The numerical ranges of the above-mentioned respective dimensions are merely examples and may be appropriately set to appropriate numerical values ​​from the perspective of operability according to the configuration of the device.

[0180] Here, the button switches 6R and 6L have curved (convex arc-shaped) end portions 6cR and 6cL outside the flat portions 6pR and 6pL along the finger insertion direction ID. The end portions 6cR and 6cL are located upstream (radially outward relative to the reference center of the wearing space FS) in the pressing direction of the button switches 6R and 6L relative to the corner portions 20eR and 20eL between the outer peripheral surface and the side surface of the outer cover 20 of the main body 2.

[0181] In other words, the ends 6cR and 6cL of the button switches 6R and 6L are configured to form a part of the corner between the outer peripheral surface and the side surface of the main body 2. In the case of this configuration, the user can press the button switches 6R and 6L as if the user presses the corner of the generally arc-shaped structure including the outer cover 20 of the main body 2 and the button switches 6R and 6L. In the case of this configuration, the button switches 6R and 6L can be easily pressed even in a small-sized main body 2. In particular, the corner of the structure has a shape that is easily perceived by the touch of a finger in a blind operation, and the pressing operation can be performed by relying on the touch of the corner, thereby improving operability.

[0182] In the present embodiment, the end portions 6cR and 6cL are end portions having curved surfaces with respect to the flat portions 6pR and 6pL, but they may be corner portions formed by straight surfaces.

[0183] Dimensional relationship between touch sensor 5 and switches 6R and 6L, etc.

[0184] Fig.211 is a top view showing the configuration of the operation surface of the ring-type device 1, and is a diagram illustrating the shape and configuration relationship of the touch sensor 5 and the button switches 6R and 6L. The sizes and configuration of the button switches 6R and 6L are determined by various sizes based on the center 5e (center of the annular shape of the first boundary recognition rib 25) of the touch sensor 5 (optical sensor unit 5c) when the operation surface of the body 2 is observed in a plan view.

[0185] For example, the combined width BD of the button switches 6R and 6L in the finger insertion direction ID is configured to be 25.0 mm or less, preferably 10.0 mm or less. In addition, the shortest distance SD between the touch sensor 5 and the button switches 6R and 6L is configured to be 1.5 mm or more, and the longest distance LD is configured to be 20.0 mm or less. It should be noted that this numerical range is suitable for the ring-type device 1 of the present embodiment. In other words, this numerical range is merely an example and can be appropriately set so as to minimize the amount of finger movement between the touch sensor 5 and the button switches 6R and 6L and to keep the amount of finger movement used for operation within a reasonable range.

[0186] The width DD of the button switches 6R and 6L in the circumferential direction (direction from the front side to the rear side) of the main body 2 is configured to be 8.0 mm or more even in the narrowest area. The size and shape of the button switches 6R and 6L are preferably configured so that: when used by a person with large fingers, the button switches 6R and 6L can be easily pressed with the ball of the thumb when the finger is inserted until the base of the finger is in the wearing space FS. It is to be noted that the above numerical range is only an example and can be appropriately set according to the device configuration.

[0187] The first finger rest 223 and the second finger rest 224 are configured to have concave curved surfaces in the present embodiment, but may also be configured to have flat surfaces, and at least one of the width in the finger insertion direction ID and the width in the circumferential direction of the body 2 is configured to be 10.0 mm or larger. In particular, the size and shape of the first finger rest 223 are preferably set so that it provides enough space for the thumb, which is the largest finger.

[0188] Fig. 221 is a schematic front view of a ring-type device 1d according to a modified example. The ring-type device 1d is provided with a structure for preventing the user from wearing the ring-type device 1d in a manner in which the front and rear sides are reversed. Specifically, the ring-type device 1d is provided with a protrusion 22e4 as a structure for giving the user a sense of strangeness when the ring-type device 1d is worn incorrectly. The protrusion 22e4 is the rear end portion of the operation surface 22o and is provided between the operation surface 22o and the second finger rest 224, and the touch sensor 5 and the button switches 6R and 6L are arranged on the operation surface 22o along the circumference of the main body 2. The front end portion of the operation surface 22o on the opposite side, that is, the portion between the operation surface 22o and the first finger rest 223, is configured as a flat portion 22e3. That is, the rear end portion and the front end portion of the operation surface 22o are configured to be asymmetrical in shape.

[0189] When the ring-type device 1d is incorrectly worn in a manner in which the front and rear sides are reversed, the thumb is placed on the second finger rest 224, and during operation, the thumb moves back and forth between the second finger rest 224 and the operation surface. Therefore, by providing the protrusion 22e4 having a shape that prevents the thumb from moving back and forth between the second finger rest 224 and the operation surface as described above, when the device is normally worn, the smooth movement of the thumb is hindered, so that the user can feel a sense of strangeness. This allows the user to recognize that the device is in a state of being incorrectly worn.

[0190] When the device is worn incorrectly, the configuration that gives the user a sense of strangeness is not limited to the above-mentioned protrusion 22e4. For example, the shapes of the first finger rest 223 and the second finger rest 224 can be made different from each other to give the user a sense of strangeness. For example, by configuring the first finger rest 223 into a concave shape and configuring the second finger rest 224 into a flat shape, the stable thumb placement state when worn normally can give the user a sense of strangeness that the thumb is not properly fitted, thereby making the user aware of incorrect wearing.

[0191] It is also assumed that the user may want to wear the ring-type device in a manner that the button switches 6R and 6L are on the front side and the touch sensor 5 is on the back side. That is, there may be quite a few users who wear the ring-type device in a manner that the front and back sides are reversed. In this case, the control unit 10 can be configured to process the input to the touch sensor 5 and the button switches 6R and 6L in a manner that the input signal is vertically and horizontally reversed to meet the user's needs.

[0192] Circumferential configuration of the operating part

[0193] Reference FIG. 23A to FIG. 25B , the relative configuration of the touch sensor 5 and the button switches 6R and 6L in the ring-type device 1 of the present embodiment with respect to the contact position of the finger on the inner surface 21 of the exterior 20 of the main body 2 will be described.

[0194] Fig.23A 1 is a schematic front view of the ring-type device 1 of the present embodiment, showing a state when the user presses the button switches 6R and 6L with the finger FO. Fig. 23B 1 is a schematic front view of the ring-type device 1 according to the present embodiment, and shows a state when a user presses the touch sensor 5 with a finger FO.

[0195] like Fig.23A As shown in other figures, when the ring-type device 1 is observed in the insertion direction ID of the finger into the wearing space FS, the imaginary line along the operation surface 22o (the surface on which the touch sensor 5 and the button switches 6R and 6L are arranged along the circumferential direction of the main body 2) of the outer surface 22 of the outer casing 20 of the main body 2 is defined as AL. In addition, an imaginary line (imaginary reference line) passing through the deepest part P of the inner surface 21 of the outer casing 20 of the main body 2 and perpendicular to the imaginary line AL is defined as FL. In the ring-type device 1 of the present embodiment, when observed from the insertion direction ID of the finger, the touch sensor 5 and the button switches 6R and 6L arranged in the circumferential direction of the main body 2 are arranged on opposite sides of the imaginary line FL (symmetrical in the circumferential direction relative to the imaginary line FL). That is, the touch sensor 5 is located on the front side (one side, the first side) of the main body 2 relative to the imaginary line FL, and the button switches 6R and 6L are located on the rear side (the other side, the second side) of the main body 2 relative to the imaginary line FL.

[0196] The deepest portion P of the inner surface 21 for determining the imaginary line FL may be defined as a position where the finger FI inserted into the wearing space FS is always in contact with the inner surface 21. Alternatively, the imaginary line FL may be an imaginary line passing through the reference center F2C of the finger inserted into the wearing space FS and perpendicular to the imaginary line AL. Alternatively, the deepest portion P may be defined as a position included in an area of ​​the inner surface 21 that is located opposite to an area where the first arm 3 and the second arm 4 overlap relative to the reference center F2C of the finger inserted into the wearing space FS.

[0197] The ring-type device 1 of the present embodiment is configured so that the touch sensor 5 as the first operating part and the button switches 6R and 6L as the second operating part are arranged along the circumference of the main body 2. Therefore, the force received by the touch sensor 5 from the finger FO through the pressing operation may include a component force that generates a moment with the contact area of ​​the finger FI and the inner surface 21 including the deepest part P as the base point relative to the main body 2. Similarly, the force received by the button switches 6R and 6L from the finger FO when being pressed may include a component force that generates a moment with the contact area of ​​the finger FI and the inner surface 21 including the deepest part P as the base point relative to the main body 2. Due to the layout in which the touch sensor 5 and the button switches 6R and 6L are arranged along the circumference of the main body 2, such a moment is inevitably generated. However, by arranging the touch sensor 5 and the button switches 6R and 6L arranged close to each other in the circumference of the main body 2 on opposite sides of the imaginary line FL, the magnitude of the generated moment can be minimized.

[0198] Fig.24A is a schematic front view of the ring-type device 1e of the third comparative example, showing a state when the user presses the button switches 6R and 6L with the finger FO. Fig. 24B 1 is a schematic front view of the ring-type device 1 e according to the third comparative example, showing a state when the user presses the touch sensor 5 with the finger FO.

[0199] like Fig.24A and Fig. 24B As shown, the ring-type device 1e of the third comparative example is configured so that the touch sensor 5 and the button switches 6R and 6L are configured so that the touch sensor 5 overlaps with the imaginary line FL when viewed in the finger insertion direction ID. That is, the touch sensor 5 and the button switches 6R and 6L arranged along the circumference of the main body 2 are arranged close to the rear side in the circumference of the main body 2 (biased toward the rear side relative to the imaginary line FL). In this configuration, as shown in FIG. Fig. 24B As shown, the magnitude of the above-mentioned moment when the touch sensor 5 is pressed can be reduced.

[0200] However, if Fig.24A As shown, when the button switches 6R and 6L are pressed, the magnitude of the torque generated cannot be reduced, and a force that moves the main body 2 toward the rear side in the circumferential direction may act on the main body 2. This may cause the ring-type device 1e to rotate relative to the finger FI inserted into the wearing space FS, and the wearing state of the ring-type device 1e relative to the finger FI may become unstable.

[0201] In the ring-type device 1e of the third comparative example, the button switches 6R and 6L are arranged away from the rear side in the circumferential direction relative to the finger FO. Since the finger FO approaches the layout of the button switches 6R and 6L from the front side to the rear side in the circumferential direction, the direction of the pressing force of the finger FO when pressing the button switches 6R and 6L approaches the direction from the front side to the rear side in the circumferential direction. As a result, the magnitude of the above-mentioned moment generated in the main body 2 increases, and it is easy to generate a force that rotates the ring-type device 1e relative to the finger FI inserted into the wearing space FS.

[0202] Fig.25A is a schematic front view of the ring-type device 1f of the fourth comparative example, showing a state when the user presses the button switches 6R and 6L with the finger FO. Fig.25B 1 is a schematic front view of a ring-type device 1f according to a fourth comparative example, showing a state when a user presses the touch sensor 5 with a finger FO.

[0203] like Fig.25A and Fig.25B As shown, the ring-type device 1f of the fourth comparative example is constructed so that the touch sensor 5 and the button switches 6R and 6L are arranged so that the button switches 6R and 6L overlap with the imaginary line FL when viewed in the insertion direction ID of the finger. That is, the touch sensor 5 and the button switches 6R and 6L arranged along the circumference of the main body 2 are arranged close to the front side in the circumference of the main body 2 (biased toward the front side relative to the imaginary line FL).

[0204] As described above, the finger FO (especially when the finger FO is a thumb) is in a posture approaching the touch sensor 5 and the button switches 6R and 6L from the front side toward the rear side in the circumferential direction of the main body 2. Therefore, the direction of the pressing force of the finger FO tends to include an angle from the front side to the rear side, so even when the touch sensor 5 or the button switches 6R and 6L are pressed, the magnitude of the torque generated is reduced.

[0205] However, if Fig.25B As shown, when pressing the button switches 6R and 6L arranged near the front side of the main body 2, unless the angle of the finger FO is adjusted (especially when the finger FO is the thumb), it is difficult to press the button switches 6R and 6L, and the posture during the pressing operation becomes uncomfortable. Therefore, the wearing state of the ring-type device 1f on the finger FI may become unstable, which may cause erroneous operation.

[0206] Compared with the third and fourth comparative examples, the ring-type device 1 of the present embodiment can stabilize the wearing state of the ring-type device 1 on the finger FI, and can also obtain stable operability without forcing the finger FO to take an unnatural posture during the pressing operation.

[0207] In the present embodiment, the second boundary identification rib 26 is a single rib extending continuously in the circumferential direction of the finger, but is not limited to this configuration. For example, the rib may be divided in the circumferential direction, that is, a plurality of ribs extending in the circumferential direction may be arranged continuously in the circumferential direction. Alternatively, a plurality of protrusions may be arranged continuously in the circumferential direction.

[0208] In the present embodiment, the first boundary identification rib 25 is a single rib formed in a continuous annular shape, but is not limited to this configuration. For example, it may not be a completely closed annular shape, but may be a roughly C-shaped rib in which a portion of the circle is interrupted. Alternatively, for example, a plurality of ribs each extending in a circular arc shape may be continuously configured in an annular shape. Alternatively, a plurality of protrusions may be continuously configured in an annular shape. In addition, the annular shape is not limited to a perfect circle as in the present embodiment, but may be an ellipse. Alternatively, it may be a polygonal shape instead of a circle.

[0209] Second embodiment

[0210] Reference FIG. 26A to FIG. 28 A ring-type device 1g according to a second embodiment of the present invention is described. Here, the configuration of the second embodiment that is different from the configuration of the first embodiment will be described. The same reference numerals will be used to represent the configuration of the second embodiment that is common to the configuration of the first embodiment, and the description thereof will be omitted.

[0211] In this embodiment, when viewed in the direction of the rotation axis 32x of the first arm 3b or the rotation axis 42x of the second arm 4b, the first arm 3b closest to the inner surface 21 of the body 2 and the second arm 4b closest to the inner surface 21 have an overlapping area.

[0212] like FIG. 26A to FIG. 27A As shown, in the ring-type device 1g of this embodiment, at least the distal ends of the first arm 3b and the second arm 4b are offset from each other in the insertion direction ID. That is, the ring-type device 1g is worn in such a manner that both the first arm 3b and the second arm 4b are in contact with the finger F. FIG. 26A to FIG. 26C As shown, when viewed in the direction along the insertion direction ID or the rotation axis 32x or 42x, the overlapping area between one arm and the other arm gradually widens in the order of areas OR3, OR2, and OR1 from the finger F3 to the finger F1.

[0213] In this way, the first arm 3b and the second arm 4b are alternately arranged in the insertion direction ID, so that compared with the ring-type device 1 of the first embodiment, the external shape of the ring-type device 1g in the direction perpendicular to the insertion direction ID is compressed, and the ease of grasping when worn on the finger F can be improved.

[0214] like Fig.27AAs shown, the first arm 3b and the second arm 4b may be configured to have a shape that is substantially symmetrical in the insertion direction ID. Fig.27A The first arm 3b and the second arm 4b shown are configured so that the width in the insertion direction ID gradually narrows as they approach the distal end. According to this configuration, for example, Figure 4C In the third wearing mode shown, the first arm 3b and the second arm 4b are prevented from interfering with the grip of the fingers.

[0215] like Fig.27A As shown, the distance Wt from the outer end of the distal surface of the first arm 3b to the outer end of the distal surface of the second arm 4b in the insertion direction ID may be 20 mm or less, or may be equal to or less than the width of the body 2 in the insertion direction ID. More preferably, the distance Wt is 8 mm or less, which is suitable for accommodating the first arm 3b and the second arm 4b between the first joint and the second joint of the finger F.

[0216] In addition, if Fig.27B As shown, the width in the insertion direction ID may be different between the first arm 3c and the second arm 4c. That is, the width W3 in the insertion direction ID at the end side of the first arm 3c is configured to be larger than the width W4 in the insertion direction ID at the end side of the second arm 4c. For example, the width may be set according to the difference between the applied force of the torsion coil spring 32s and the applied force of the torsion coil spring 42s so that the force applied to the finger F by the first arm 3c and the force applied to the finger F by the second arm 4c are uniform.

[0217] like Fig.28 As shown, the first arm 3d and the second arm 4d can be arranged in a comb-like shape in a staggered manner in the insertion direction ID. That is, the second arm 4d has a first half arm 4d1 and a second half arm 4d2 in a pair, and the first arm 3d is arranged between the first half arm 4d1 and the second half arm 4d2 in the insertion direction ID. The combined structure of the first arm 3d and the second arm 4d is symmetrical about the insertion direction ID, and the finger F can be inserted into the wearing space FS in the same manner from the left or right side of the insertion direction ID. That is, when the ring-type device 1g is worn on the finger F, there is no need to worry about the insertion direction, and the wearability can be improved.

[0218] The above-mentioned embodiments can be combined with each other as much as possible.

[0219] According to the present invention, the operability of a ring-type device having a plurality of operating parts can be improved.

[0220] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
