DETAILED DESCRIPTION

[0017] Reference Figure 1A , Figure 1B to Figure 3 , an embodiment of the wrist-worn device of the present invention is described. In this embodiment, the case where the wrist-worn device is a watch is exemplified.

[0018] In the embodiments described below, various technically preferred limitations are added in order to implement the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0019] Figure 1A and Figure 2A This is a front view of a wristwatch serving as a wrist-worn device according to this embodiment. Figure 1B and Figure 2B This is a side view of a wristwatch serving as a wrist-worn device according to this embodiment.

[0020] in addition, Figure 3 This is a block diagram showing the main parts of the control structure of the wristwatch according to this embodiment.

[0021] like Figure 1A , Figure 1B as well as Figure 2A , Figure 2B As shown, the wristwatch 100 of the present embodiment includes a case (hereinafter referred to as a “watch case 1 ” in the embodiment).

[0022] The watch case 1 is formed of, for example, metal such as stainless steel or titanium, ceramics, various synthetic resins, etc. The material forming the watch case 1 is not limited to the materials exemplified here.

[0023] The watch case 1 of the present embodiment is formed in a hollow short column shape that is open at the top and bottom in the thickness direction.

[0024] A windproof member (not shown) made of, for example, transparent glass is attached to the opening on the front side (visible side) of the watch case 1 to block the opening on the front side. The opening on the back side of the watch case 1 is closed by a back cover (not shown).

[0025] A plurality of operation buttons 11 (a first operation button 11, a second operation button 11, ...) are provided on the side surface of the watch case 1 (the outer periphery of the watch case 1), and the plurality of operation buttons are used to input various operation instructions such as instructions for time alignment, instructions for switching the display screen 124 described later, instructions for switching modes, etc.

[0026] In this embodiment, four operation buttons 11 are arranged at approximately equal intervals (in the example shown in the figure, they are arranged at the 2 o'clock side, the 4 o'clock side, the 8 o'clock side, and the 10 o'clock side of the analog clock, respectively). The number and arrangement of the operation buttons 11 are not limited to the example shown in the figure. The operation button 11 may be one or more than five.

[0027] In this embodiment, the operation button 11 is an operation detection unit (controller) that detects input operation, and constitutes the first input unit 10 (see Figure 3 ). The operation button 11 is, for example, a push button that generates an input operation signal by being pressed. The first input unit (first controller) 10 is not limited to the operation button 11 being a push button, and may include, for example, a crown (not shown) that generates an input operation signal by being pulled out and rotated.

[0028] In the state where the first switch contact 10a is connected (see Figure 3 When the CPU 41 as the control unit receives the input operation signal generated by the operation button 11,

[0029] The watch case 1 is attached with the watch band 2 so that the watch body including the watch case 1 can be worn on the wrist.

[0030] In addition, a dial 120 is provided on the surface side (visual recognition side) of the watch 100 and below the windshield member, and the dial 120 is provided with a pointer 123 of the display unit 12, a display screen 124, etc. The layout of the dial 120 is not limited to the illustrated example. Figure 1A In the examples, the case where two hands 123 are provided is illustrated, but the hands 123 may include three hands of a second hand, a minute hand, and an hour hand or other various functional hands.

[0031] Furthermore, the various components of the display unit 12, a watch module (not shown), etc. are housed inside the watch case 1. The watch module operates the various components of the watch 100, such as the display unit 12. The watch module includes, for example, a CPU 41, a memory 42, various circuits, etc. (see Figure 3 ) and mounted on a substrate not shown in the figure.

[0032] Furthermore, on the surface side (the side on which the watch is viewed) of the watch case 1 of the present embodiment, an annular bezel 3 is provided so as to surround the windshield member.

[0033] The bezel 3 has an upper surface portion 31 disposed on the surface side of the watch case 1 (the side viewed from the watch) and around the windshield member, and a side surface portion 32 provided perpendicularly from the upper surface portion 31 and disposed along the peripheral surface of the watch case 1 .

[0034] like Figure 1B and Figure 2B As shown, the window portions 33 are formed at four locations on the side surface portion 32 corresponding to the operation buttons 11 .

[0035] In the present embodiment, in the watch 100 as a wrist-worn device, the frame 3 functions as a cover member that can take a first position that exposes the operation button 11 as the first input unit (first controller) 10 and a second position that covers the first input unit 10 .

[0036] The bezel 3 is configured to be rotatable at least by a certain angle along the outer circumference of the watch case 1 , and can take a first position and a second position by rotating.

[0037] The bezel 3 only needs to be rotatable at least to a certain angle along the outer circumference of the watch case 1 , and its shape and the like are not limited to the illustrated example.

[0038] The rotation direction of the bezel 3 can be either clockwise or counterclockwise, or can be rotated in both directions. Figure 2A As shown by the hollow arrow in FIG. 1 , the case where the bezel 3 rotates clockwise is illustrated.

[0039] In the present embodiment, the window portion 33 is arranged at a position corresponding to the operation button 11 as the first input unit 10 ( Figure 1A as well as Figure 1B The state shown in FIG. 1 is a state in which the bezel 3 is located at the first position in which the operation button 11 is exposed. In addition, the bezel 3 is rotated so that the portion other than the window portion 33 is arranged at a position corresponding to the operation button 11 as the first input portion ( FIG. 10 ). Figure 2A as well as Figure 2B The state shown in FIG. 1 is a state in which the bezel 3 is located at the second position covering the operation button 11.

[0040] As described above, in this embodiment, a plurality of operation buttons 11 are provided as the first input unit, and when the bezel 3 as the cover member is in the second position, the plurality of operation buttons 11 are covered by the bezel 3 .

[0041] The bezel 3 may expose the operation button 11 as the first input unit at the first position and cover the first input unit at the second position, and its shape and the like are not limited to the illustrated example.

[0042] For example, a portion (window portion 33) for exposing the operation button 11 is provided according to the position of the first input portion. In the illustrated example, the operation button 11 as the first input portion is arranged at four locations on the side of the watch case 1, so the window portion 33 is also provided on the side portion 32 of the watch frame 3, but in the case where the operation button 11 is arranged on the surface side of the watch case 1 (the visual recognition side of the watch), the window portion 33 is also provided on the upper portion 31 of the watch frame 3.

[0043] Next, refer to Figure 3 The functional structure of the wristwatch 100 will be described.

[0044] like Figure 3 As shown, the wristwatch 100 includes a CPU 41 (Central Processing Unit) as a control unit, and a memory 42 composed of a ROM (Read Only Memory) and a RAM (Random Access Memory) (not shown).

[0045] The CPU 41 performs various calculations as a processor and comprehensively controls the overall operation of the wristwatch 100 .

[0046] The memory 42 stores various programs executed by the CPU 41 and various data used in the various programs. The CPU 41 reads out and executes and uses these programs and data as needed.

[0047] The wristwatch 100 also includes an oscillation circuit 43 , a frequency division circuit 44 , and a timing circuit 45 (timing unit).

[0048] The oscillation circuit 43 generates a predetermined frequency signal and outputs it to the frequency division circuit 44. The frequency division circuit 44 divides the frequency signal input from the oscillation circuit 43, generates a signal of a frequency set according to a control signal from the CPU 41, and outputs it to the CPU 41. In addition, the frequency division circuit 44 generates a predetermined frequency signal (for example, a 1-second signal) and outputs it to the timing circuit 45.

[0049] The timer circuit 45 is a counter that counts the input frequency signal to count the date and time (current time). The counter is not limited to a counter circuit having a hardware configuration, but may be a RAM or the like that stores the date and time counted by the CPU 41 in software.

[0050] As described above, the watch 100 is provided with a display unit 12 (in this embodiment, an analog display unit 12a and a digital display unit 12b). The CPU 41 controls each part of the display unit 12, and displays the date and time (current time) counted by the timing circuit 45 on the dial 120.

[0051] The date and time (current time) may be displayed in an analog format or a digital format, or in a combination of the analog format and the digital format.

[0052] The analog display unit 12 a includes a stepping motor 121 , a motor drive circuit 122 , a gear train mechanism (not shown), the above-mentioned pointer 123 , and the like.

[0053] The motor drive circuit 122 outputs a drive pulse to the stepping motor 121 based on a control signal input from the CPU 41 .

[0054] The stepping motor 121 is driven in a stepping manner (rotates at a predetermined step angle) based on the voltage waveform of the driving pulse input from the motor driving circuit 122 .

[0055] The rotation of the stepping motor 121 is transmitted to the pointer 123 via the gear train mechanism as a gear train, whereby the pointer 123 (e.g., the hour hand, the minute hand) moves (rotates) in the forward direction or the reverse direction by a predetermined angle each time. Thus, the pointer 123 indicates the date and time (current time) on the dial 120.

[0056] The digital display unit 12 b includes a display screen 124 , a display control circuit 125 , and the like.

[0057] The display screen 124 is composed of a liquid crystal display (LCD: Liquid Crystal Display), an organic EL display (OEL: organic electro-luminescent Display), or other flat panel displays.

[0058] The display control circuit 125 controls the display of the display screen 124 based on the control signal input from the CPU 41 , thereby displaying the date and time (current time) and the like on the display screen 124 provided on the dial 120 .

[0059] In addition, the CPU 41 as a control unit receives input operations from the first input unit (first controller) 10 and the second input unit (second controller) 20 .

[0060] The first input unit 10 includes at least one operation button 11 (in the present embodiment, four operation buttons 11 as described above), and when the user operates each operation button 11, an input operation signal corresponding to the operation is generated.

[0061] The second input unit 20 includes a motion detection unit 21 that detects the user's input operation and generates an input operation signal corresponding to the detection result. The motion detection unit 21 is, for example, an acceleration sensor that detects the acceleration of the watch 100 as a wrist-worn device. The motion detection unit 21 is not limited to an acceleration sensor. As long as it is a unit that can detect the movement of the watch 100 that can be converted into an input operation, it can also be other sensors such as a gyro sensor that detects the rotation of the watch 100.

[0062] Here, the user input operation detected by the acceleration sensor or the like as the motion detection unit 21 is a predetermined motion such as swinging the arm once, swinging the arm twice quickly, etc. Which motion corresponds to which input operation is set and registered in advance.

[0063] When detecting such a predetermined motion, the motion detection unit 21 detects an input operation corresponding to the motion and generates an input operation signal.

[0064] In addition to the case where the user performs a predetermined action, the acceleration sensor or the like as the action detection unit 21 also continuously detects the acceleration or the like of the watch 100 at any time. The acceleration data or the like detected by the acceleration sensor or the like as the action detection unit 21 is output to the CPU 41 as the control unit at any time, and the CPU 41 receives the data and reflects it on the display of the display unit 12 or the like.

[0065] When the bezel 3 as the cover member is located at the first position where the operation button 11 as the first input unit is exposed, that is, when the operation button 11 is exposed from the window 33 , the user can operate the operation button 11 .

[0066] In this state, the first switch contact 10a is turned on ( Figure 3 The input operation signal generated by the operation button 11 is received by the CPU 41. Figure 1A As shown, characters "OFF" or the like may be displayed on the display screen 124 of the digital display unit 12b, which indicates that the input operation of the operation button 11 is valid and the input operation from the motion detection unit 21 is invalid (OFF).

[0067] In contrast, when the frame 3 is in the second position covering the operation button 11 and protecting the operation button 11 from external forces, that is, when the operation button 11 is covered by a portion other than the window portion 33, the user cannot operate the operation button 11 and the operation button 11 cannot be accessed from the outside.

[0068] In this state, the second switch contact 20a is switched on, and the input operation signal generated from the second input unit 20 (motion detection unit 21 such as an acceleration sensor) is received by the CPU 41. Figure 2A As shown, characters “ON” and the like may be displayed on the display screen 124 of the digital display unit 12 b , indicating that the input operation from the motion detection unit 21 is valid (ON).

[0069] Thus, in this embodiment, when the operation button 11 is protected and cannot be touched, the input operation detected by the second input unit (second controller) 20 as a controller other than the operation button 11 becomes valid. Thus, the input operation can be performed without performing the operation of returning the bezel 3 to the first position.

[0070] Next, refer to Figure 1A and Figure 1B , Figure 2A and Figure 2B The operation of the wristwatch 100 according to this embodiment will be described.

[0071] exist Figure 1B and Figure 2B In FIG. 1 , the operation button 11 which is covered by the side surface portion 32 of the bezel 3 and cannot be actually seen is indicated by a dotted line.

[0072] When the user wants to operate the watch 100 by using the operation button 11, the position of the bezel 3 is adjusted to the first position where the operation button 11 is exposed from the window 33. At this time, all the operation buttons 11 (four operation buttons 11 in this embodiment) provided on the watch 100 are exposed from the window 33 and are in an operable state.

[0073] When the user appropriately operates the operation button 11 to perform an input operation corresponding to an action such as switching the display screen 124 to a desired display, an input operation signal corresponding to the operation is input to the CPU 41. Thus, an action corresponding to the input operation signal such as switching the display screen 124 is performed.

[0074] When the user does not want to touch the operation button 11, or wants to protect the operation button 11 to avoid external contact, the position of the bezel 3 is adjusted so that the portion other than the window portion 33 is arranged at a position corresponding to the operation button 11, and the operation button 11 is covered by the bezel 3 (the side portion 32 of the bezel 3). At this time, all the operation buttons 11 (four operation buttons 11 in this embodiment) provided on the watch 100 are covered by the bezel 3 (the side portion 32 of the bezel 3) and become inoperable.

[0075] When the bezel 3 is in the second position, the connection is switched from the first switch contact 10a being on to the second switch contact 20a being on, and the input operation signal from the second input unit 20 (second controller, acceleration sensor, etc. motion detection unit 21) becomes valid.

[0076] For example, when the motion detection unit 21 is an acceleration sensor, if an acceleration corresponding to a predetermined motion among the accelerations of the watch 100 is detected, the motion detection unit 21 generates an input operation signal corresponding to the motion. Furthermore, when the bezel 3 is located at the second position, the CPU 41 receives the input operation signal from the second controller, i.e., the motion detection unit 21.

[0077] Specifically, for example, by associating different operation instruction contents with predetermined actions such as slowly swinging the watch 100, swinging it once quickly, swinging it twice slowly, and swinging it twice quickly, an input operation signal corresponding to the acceleration detected by the acceleration sensor is generated and received by the CPU 41. Thus, desired operations such as switching the display screen 124 can be performed.

[0078] For example, each time the watch 100 is swung significantly once, the content displayed on the display screen 124 can be switched to time display, step count, calories burned, etc., or the time display mode can be switched to the stopwatch mode, and the start / stop operation can be performed by quickly swinging the watch 100 twice.

[0079] The correspondence between the acceleration information of the watch 100 detected by the motion detection unit 21 and the input operation signal generated by the motion detection unit 21 (i.e., what kind of input operation is assumed to exist when what kind of motion is detected) can be set by default or arbitrarily set by the user. In addition, when there is a default setting, the user can also reset it appropriately for customization.

[0080] Thus, even after the bezel 3 is temporarily rotated to the second position where the operation button 11 is covered and protected, input operations can be performed through the second input unit 20 (second controller, acceleration sensor, etc. motion detection unit 21) without returning the bezel 3 to the first position.

[0081] As described above, according to the present embodiment, the watch 100 as a wrist-worn device comprises: an operation button 11 as a first input unit 10 (i.e., a first controller for detecting input operations); a second input unit 20 different from the first input unit 10 (i.e., an action detection unit 21 such as an acceleration sensor as a second operation detection unit for detecting input operations); a bezel 3 as a cover part, which is capable of taking a first position in which the first input unit 10 is exposed and a second position in which the first input unit 10 is covered; and a CPU 41 as a control unit, which receives input operations detected by the first input unit 10 and the second input unit 20, and when the bezel 3 is in the second position, the CPU 41 makes the input operation detected by the second input unit 20 (the action detection unit 21 such as an acceleration sensor as a second controller for detecting input operations) valid.

[0082] Thus, even after the bezel 3 is temporarily rotated and moved to the second position where the operating button 11 is covered, there is no need to return the bezel 3 to the first position, and input operations can be performed through the second input unit 20 (motion detection unit 21 such as an acceleration sensor) that is different from the operating button 11, thereby realizing a watch 100 with excellent operability.

[0083] In addition, in this embodiment, the second input unit (second controller) 20 includes a motion detection unit 21 such as an acceleration sensor for detecting the acceleration of the watch 100. When the watch frame 3 is in the second position, the CPU 41 accepts input operations corresponding to the acceleration detected by the motion detection unit 21, i.e., the acceleration sensor.

[0084] Thus, the user can easily operate the watch 100 by performing a predetermined action such as swinging the arm wearing the watch 100 a predetermined number of times at a predetermined speed (ie, slowly or quickly), thereby achieving excellent operability.

[0085] In addition, the cover member of the present embodiment is the bezel 3 which is set to be rotatable at least by a certain angle, and the bezel 3 is configured to be able to take the first position and the second position by rotating.

[0086] This eliminates the need to provide a separate cover member, and allows the bezel 3 mounted on the watch 100 to be used as a cover member. Therefore, the watch 100 can be provided with good operability without increasing the number of components or compromising the design.

[0087] In addition, in the present embodiment, the first input unit (first controller) 10 includes a plurality of operation buttons 11 (first button and second button), and these plurality of operation buttons 11 are all covered by the bezel 3 (side surface 32 of the bezel 3) when the bezel 3 is in the second position.

[0088] Thus, by rotating the bezel 3 only once, the plurality of operation buttons 11 can be brought into a covered state where they are protected at the same time, and the first position and the second position can be switched with minimal operation.

[0089] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments.

[0090] Of course, various modifications can be made without departing from the gist of the invention.

[0091] For example, in this embodiment, setting Figure 3The first switch contact 10a and the second switch contact 20a shown in the figure switch the connection state between the first switch contact 10a and the second switch contact 20a and the CPU 41 by rotating the watch frame 3, thereby mechanically switching the connection / disconnection of the first input unit 10 and the second input unit 20. However, the connection / disconnection of the first input unit 10 and the second input unit 20 is not limited to mechanical switching.

[0092] For example, it is possible to switch under what circumstances the input operation signal from which of the first input unit (first controller) 10 and the second input unit (second controller) 20 is processed as valid by software processing. In this case, there is no need to set Figure 3 The first switch contact 10a and the second switch contact 20a shown in the figure simplify the device structure.

[0093] In the present embodiment, the display unit 12 is constituted by the analog display unit 12a that displays the time using the pointer 123 and the digital display unit 12b having the small window-like display screen 124, but the structure of the display unit 12 is not limited to this.

[0094] For example, Figure 4A and Figure 4B As shown, the display screen 124 of the digital display unit 12 b may be provided on the entire surface of the dial 120 .

[0095] In this way, when characters or the like are displayed in a large area of ​​the dial 120, the position of the pointer 123 can be moved so that the pointer 123 of the analog display portion 12a does not interfere with the digital display.

[0096] For example, when the digital display unit 12b is used as the main display unit, it is possible to display the digital display unit 12b independently of the actual time. Figure 4B As shown in FIG. 1 , the pointer 123 is arranged so as to divide the dial 120 into a horizontal line shape up and down and move the pointer 123. In addition, the arrangement of the pointer 123 is not limited to Figure 4B In the example shown, the pointer 123 can be moved by arranging the pointer 123 so as to divide the dial 120 into left and right vertical lines.

[0097] In addition, for example, Figure 5A and Figure 5B As shown in FIG. 1 , the display unit 12 may be composed of only the digital display unit 12 b without the analog display unit 12 a. Figure 5A As shown, the digital display unit 12b can display a time display screen using hands like an analog clock.

[0098] And, if Figure 4A as well as Figure 4B , Figure 5A as well as Figure 5B As shown, when the display screen 124 of the digital display unit 12 b is provided in a relatively large area of ​​the dial 120 , the touch panel 22 may be formed on the display screen 124 .

[0099] When the touch panel 22 is provided, the touch panel 22 may replace the motion detection unit 21 such as an acceleration sensor, or may be included in the second input unit (second controller) 20 together with the motion detection unit 21 .

[0100] In this case, the CPU 41 as the control unit enables the input operation performed through the touch panel 22 when the watch frame 3 is located at the second position.

[0101] The CPU 41 may receive an input operation performed through the touch panel 22 as a valid operation when the bezel 3 is located at any one of the first position and the second position.

[0102] When the touch panel 22 is provided, it is possible to easily perform detailed input / setting operations that are the same as or more detailed than those of the operation buttons 11. This makes it possible to realize a wristwatch 100 that is more user-friendly.

[0103] In addition, in addition to being able to obtain a first position in which the input operation of the operation button 11 serving as the first input unit (first controller) 10 is valid and a second position in which the input operation detected by the action detection unit 21 serving as the second input unit (second controller) 20 is valid, the frame 3 serving as a cover part can also obtain a third position in which input from either the first input unit 10 or the second input unit 20 is not accepted.

[0104] In this case, when the user wants to set the operation button 11 to a protected covered state but does not want to make any changes to the display screen or mode, etc., erroneous operation due to unintended arm movement or the like can be avoided.

[0105] In addition, in the case where the second input unit 20 different from the first input unit 10 includes multiple input units such as a motion detection unit 21 and a touch panel 22, for example, when the frame 3 is in the second position, the input operation of all the input units constituting the second input unit 20 can be made valid, and when the frame 3 is in the third position, only the input operation of the touch panel 22 among the input units constituting the second input unit 20 can be made valid, etc., and the input unit can be switched to be valid.

[0106] In this way, input operations that meet the user's preferences or needs can be performed, and the operability of the wristwatch 100 is improved.

[0107] And, if Figure 4A as well as Figure 4B , Figure 5A as well as Figure 5B As shown, when the cover member (bezel 3) is located at the first position, the display content of the display unit 12 can be switched compared to when it is located at the second position.

[0108] For example, in a case where the input operation performed through the touch panel becomes effective when the cover part (table frame 3) is in the second position, when the cover part (table frame 3) is in the second position, the display content of the display unit 12 can be automatically changed to a layout that facilitates input operations through the touch panel.

[0109] In addition, in the present embodiment, the case where the cover part is a bezel 3 that rotates along the outer circumference of the watch case 1 is taken as an example, but the cover part is not limited to the bezel as long as it can take a first position that exposes the first input part (first controller) 10 and a second position that covers the first input part 10.

[0110] For example, the cover member may be a lid member or a baffle that can take a first position that exposes the first input unit 10 and a second position that covers the first input unit 10 by sliding movement or the like.

[0111] In this case, the cover member does not need to rotate along the outer circumference of the watch case 1. Therefore, the watch case 1 is not limited to Figure 1A The circular shape when viewed from above shown in the figure may be a polygon such as a quadrilateral or octagon when viewed from above.
