[First embodiment]
An example of a wristwatch band according to the first embodiment will be described with reference to FIGS. 1 to 4. FIG. 1 is a diagram showing an example of a wristwatch according to the first embodiment. FIG. 2 is a diagram showing an example of a computer and a circuit installed in the wristwatch band according to the first embodiment. As shown in FIG. 1, the wristwatch 100 includes a watch case 10, a spring bar 20, and a wristwatch band 30.

The watch case 10 is a housing that houses a mechanical movement, an hour hand, a minute hand, a second hand, etc., and is connected to a watch band 30 by a spring bar 20.

The watch band 30 includes a ticking sensor 301, an amplifier 302, a filter 303, an environment sensor 304, an oscillation circuit 305, a frequency dividing circuit 306, a ROM (Read Only Memory) 307, and a RAM (Random Access Memory). ) 308, a CPU (Central Processing Unit) 309, and a communication section 310.

The tick sensor 301 is a device that detects ticks generated inside the wristwatch 100 and generates tick data indicating the ticks. The ticking sound referred to here is, for example, a sound generated by the operation of an escapement included in the wristwatch 100. That is, the ticking sound referred to here is, for example, a sound generated when the escape wheel and pallet of the wristwatch 100 come into contact with each other. Further, the tick sensor 301 is, for example, a piezoelectric element or a microphone. Furthermore, the ticking sensor 301 is in contact with the spring bar 20 attached to the wristwatch 100.

The ticking sensor 301 detects ticking by detecting vibrations transmitted through the watch case 10 and the spring bar 20 of the wristwatch 100. Alternatively, the ticking is detected by detecting vibrations transmitted through the watch case 10 of the wristwatch 100 and the air. The engraving sensor 301 converts the detected engraving into engraving data, which is data in analog or digital format, and transmits the data to the amplifier 302 . The amplifier 302 amplifies the amplitude of the tick waveform indicated by the tick data. The filter 303 removes noise included in the waveform of the ticking sound amplified by the amplifier 302 and transmits the ticking data to the CPU 309 .

The environment sensor 304 detects a physical quantity indicating the environment outside the wristwatch 100, and generates environmental data indicating the physical quantity. The environmental sensor 304 is, for example, an acceleration sensor, a temperature sensor, an atmospheric pressure sensor, or a magnetic sensor. Further, the physical quantities indicating the external environment mentioned here include, for example, the acceleration of the wristwatch 100, the temperature around the wristwatch 100, the atmospheric pressure, and the magnitude of the magnetic field. Furthermore, the environmental data is data associated with the ticking data.

Further, as a factor that changes the magnetic field around the wristwatch 100, for example, a magnet embedded in the opening/closing part of a bag placed around the wristwatch 100 can be cited.

The oscillation circuit 305 generates a signal having a predetermined frequency, for example, 32768 Hz, and transmits it to the frequency dividing circuit 306. The frequency dividing circuit 306 divides the frequency of the signal received from the oscillation circuit 305 to generate a clock signal that serves as a reference for time measurement, and transmits it to the CPU 309 .

The ROM 307 stores a program read and executed by the CPU 309, for example, the data transmission program 3070a shown in FIG. FIG. 3 is a diagram illustrating an example of a data transmission program executed by the CPU according to the first embodiment. As shown in FIG. 3, the data transmission program 3070a includes a data acquisition function 3071a, an accuracy data generation function 3072a, and a data transmission function 3073a.

Further, the data acquisition function 3071a may further acquire environmental data generated using the environmental sensor 304. The accuracy data generation function 3072a generates accuracy data indicating the accuracy of the time displayed by the wristwatch 100, including at least one of the rate of the wristwatch 100 and the swing angle of the balance wheel included in the wristwatch 100, based on the ticking data. It is a function. Specifically, the accuracy data generation function 3072a compares the frequency of the tick waveform indicated by the tick data with the frequency of the clock signal generated by the frequency dividing circuit 306, and calculates the rate and swing angle from the difference between the two. This is a function to calculate. The accuracy data is data used in other devices to evaluate the accuracy of the time displayed by the wristwatch 100 and to notify the contents and timing of repairs based on the evaluation results. Also, the other devices mentioned here are smartphones and tablets. The data transmission function 3073a is a function of transmitting accuracy data to another device using the communication unit 310, which will be described later. Furthermore, the data transmission function 3073a may further transmit environmental data to other devices using the communication unit 310, which will be described later.

The RAM 308 stores the above-described engraving data, environment data, and accuracy data.

The CPU 309 reads and executes the data transmission program 3070a shown in FIG. As a result, the CPU 309 uses the engraving sensor 301, amplifier 302, and filter 303 to acquire engraving data, and uses the accuracy data generation function 3072a, oscillation circuit 305, and frequency dividing circuit 306 to generate accuracy data. , transmits the accuracy data to other devices using the data transmission function 3073a and the communication unit 310. Further, the CPU 309 appropriately controls each component of the wristwatch band 30 by reading and executing various programs stored in the ROM 307 .

The communication unit 310 transmits the accuracy data generated by the CPU 309 to other devices. Furthermore, the communication unit 310 may periodically transmit the accuracy data stored in the RAM 308 to other devices, or transmit the ticking data to other devices each time the accuracy data is stored in the RAM 308. You may.

The communication unit 310 may further transmit the environmental data generated by the CPU 309 to other devices.

Furthermore, the wristwatch band 30a includes a contact member 42a having a cross section taken along a plane passing through the central axis of the spring bar 20a that is convex toward the spring bar 20a. Thereby, the wristwatch band 30a can easily insert the spring bar 20a into the housing 41a even when the contact member 42a is biased toward the position where the spring bar 20a is inserted. That is, the wristwatch band 30a can be easily assembled even when the contact member 42a is biased toward the position where the spring bar 20a is inserted.

In the third embodiment, the end piece 40a is taken as an example of the end piece included in the wristwatch band 30a, but the present invention is not limited to this. For example, an example of an end piece included in a wristwatch band is an end piece 40b shown in FIG. 13. FIG. 13 is a diagram showing an example of the structure of an end piece of a wristwatch band according to another embodiment when viewed from the -Y direction side.

As shown in FIG. 13, the end piece 40b includes a housing 41b assembled from a first container 411b and a second container 412b. The housing 41a is assembled by matching the edges of the first container 411b and the second container 412b. The first container 411b and the second container 412b are connected in a swingable manner by a shaft 44b. Note that the first container 411b and the second container 412b may be assembled in another manner to form the housing 41a.

Further, when the wristwatch band includes the end piece 40b, the spring bar 20a is fixed with the spring bar housing 21a sandwiched between the edge of the first container 411b and the edge of the second container 412b. In this case, when the contact member 42a is strongly biased toward the position where the spring bar 20a is inserted, or when the cross section of the contact member 42a along the YZ plane is not bent toward the spring bar 20a, etc., it may be possible to open the first container 411b and the second container 412b to incorporate the spring bar 20a.

Further, in the third embodiment, an example is given in which the wristwatch band 30a is a metal band, but the present invention is not limited to this. For example, even if the wristwatch band 30a is made of leather, urethane, silicone, etc., it may not have a built-in structure similar to the end piece 40a shown in FIG. 11 or the end piece 40b shown in FIG.

[Fourth embodiment]
An example of a wristwatch band according to the fourth embodiment will be described with reference to FIGS. 21 and 22. In the following description, the left half of FIGS. 21 and 22 will be described as an example. The right half of FIGS. 21 and 22 is similar to the left half of FIGS. 21 and 22.

FIG. 21 is a diagram illustrating an example of the structure of the spring bar and end piece before the watch case and end piece according to the fourth embodiment are connected by the spring bar, as viewed from the +Z direction side. As shown in FIG. 21, the spring bar 20g includes a spring bar housing 21g, a protrusion 222g, and a sealing device 24g.

The spring bar housing 21g is a cylindrical housing whose central axis coincides with the Y axis and whose bottom surface is parallel to the ZX plane. The bottom surface of the spring bar housing 21g is provided with a circular protrusion hole 212Hg whose center is located on the Y axis. Further, a spring insertion hole 25g is formed in the side surface of the spring bar housing 21g.

The protrusion 222g protrudes from the protrusion hole 212Hg to the outside of the spring bar housing 21g, and is a cylindrical member whose central axis coincides with the Y-axis. Furthermore, in the portion of the protruding portion 222g located inside the spring bar housing 21g, at least a portion of the dimension in the ZX plane is larger than the diameter of the protruding hole 212Hg. Further, the protruding portion 222g includes a circular collar 2220g projecting from the side surface. The collar 2220g contacts the watch case 10a when the spring bar 20g is attached to the watch case 10a.

The end piece 40g includes a housing 41g, a spring 42g, and a ticking sensor 43g.

The housing 41g houses a spring 42g and a ticking sensor 43g, into which a spring bar 20g is inserted. Moreover, it is preferable that the housing 41g is composed of a first container and a second container, as shown in FIG. 13. Furthermore, as shown in FIG. 21, the space between the housing 41g and the spring bar 20g may be sealed by a sealing device 50g. The sealing device 50g is a seal that seals between the housing 41g and the spring bar 20g.

The spring 42g is an elastic member whose one end is connected to the housing 41g, the other end is inserted into the spring insertion hole 25g, and pushes the protrusion 222g toward the outside of the spring bar housing 21g. The elastic member referred to here is, for example, a leaf spring. FIG. 22 is a diagram illustrating an example of the structure of the spring bar and end piece when the watch case and end piece according to the fourth embodiment are connected by the spring bar, as viewed from the +Z direction side. As shown in FIG. 22, the spring 42g is bent inward on the spring insertion hole 25g side when the watch case 10a and the end piece 40g are connected by the spring bar 20g. The tick sensor 43g is attached to the spring 42g.

The wristwatch band according to the fourth embodiment has been described above. A ticking sensor 43g included in the wristwatch band is attached to a spring 42g. As a result, the watch band acquires vibrations caused by the ticking generated inside the watch case 10a and transmitted to the watch case 10a by the protrusion 222g alone, and transmits the vibrations to the spring 42g and the ticking sensor 43g. Therefore, the wristwatch band can acquire ticking data indicating more accurate ticking.

The wristwatch band also includes a sealing device 50g that seals between the spring bar 20g and a housing 41g in which the spring bar 20g is housed. Thereby, the wristwatch band can suppress moisture such as sweat of the user wearing the wristwatch from entering between the housing 41g and the spring bar 20g.

The wristwatch band also includes a sealing device 24g that seals between the protrusion hole 212Hg and the protrusion 222g. Thereby, the wristwatch band can suppress moisture such as sweat of the user wearing the wristwatch from entering between the protrusion hole 212Hg and the protrusion 222g.

Further, the programs described in the first embodiment and the second embodiment may be programs that implement all or part of the functions described above. Note that the program that implements some of the above-mentioned functions may be a so-called difference program, which is a program that can implement the above-mentioned functions in combination with a program recorded in advance in the computer system.

Although the mode for implementing the present invention has been described above using the embodiments, the present invention is not limited to these embodiments, and various combinations, modifications, and changes may be made without departing from the gist of the present invention. Substitutions can be added.
