［概要］
図１は、本実施形態におけるバンド取付け装置を備える装着機器である時計をアナログ時計における６時側から見た要部斜視図である。図２は、図１に示す時計の要部分解斜視図である。なお、時計１００の１２時側も６時側から見た場合とほぼ同様であることから図１及び図２等では図示を省略している。
図１及び図２に示すように、本実施形態の装着機器である時計１００は、本体ケース１と、本体ケース１に連結されるバンド２と、本体ケース１にバンド２を取り付けるバンド取付け装置６（図７参照）とを含んでいる。
本実施形態では、本体ケース１及び本体ケース１に装着されるベゼル部材３（外装部材）等を含んで時計本体１０が構成されており、バンド２は本体ケース１に連結されることで時計本体１０に取り付けられる。 [overview]
Fig. 1 is a perspective view of the main parts of a watch, which is a wearable device equipped with a band attachment device in this embodiment, seen from the 6 o'clock side of an analog watch. Fig. 2 is an exploded perspective view of the main parts of the watch shown in Fig. 1. Note that the 12 o'clock side of the watch 100 is almost the same as when viewed from the 6 o'clock side, so it is not shown in Figs. 1 and 2.
As shown in Figures 1 and 2, a watch 100, which is a wearable device of this embodiment, includes a main case 1, a band 2 connected to the main case 1, and a band attachment device 6 (see Figure 7) that attaches the band 2 to the main case 1.
In this embodiment, a watch body 10 is constituted by including a main case 1 and a bezel member 3 (exterior member) attached to the main case 1, and the band 2 is attached to the watch body 10 by connecting it to the main case 1.

後述するように本実施形態のバンド２は、バンド２の幅方向（図１及び図２においてｘ方向）に貫通する第１の貫通孔２２を備えるバンド側取付け部２１を有している。本体ケース１は、バンド側取付け部２１を挟んで配置され、取付け状態において第１の貫通孔２２と連通する第２の貫通孔１４を備える本体側バンド取付け部１１（第１の本体側取付け部１２ａ）を有している。バンド側取付け部２１に形成されている第１の貫通孔２２及び本体側バンド取付け部１１（第１の本体側取付け部１２ａ）に形成されている第２の貫通孔１４には、連結ピン５が一方側（本実施形態では図１及び図２においてｘ方向右側）から挿入される。これにより、バンド側取付け部２１と本体側バンド取付け部１１（第１の本体側取付け部１２ａ）とが連結された連結部分である連結部６０（図７参照）の連結状態が維持される。そして、バンド側取付け部２１及び本体側バンド取付け部１１（第１の本体側取付け部１２ａ）を連結ピン５により連結させた状態で、連結部分（連結部６０）のうち少なくとも連結ピン５が挿入される一方側をカバー部３２により覆うことで、連結ピン５が抜けないように押さえる構成となっている。 As described later, the band 2 of this embodiment has a band-side mounting portion 21 having a first through hole 22 penetrating the width direction of the band 2 (x direction in Figs. 1 and 2). The main body case 1 has a main body-side band mounting portion 11 (first main body-side mounting portion 12a) that is arranged on either side of the band-side mounting portion 21 and has a second through hole 14 that communicates with the first through hole 22 in the mounted state. The connecting pin 5 is inserted from one side (the right side in the x direction in Figs. 1 and 2 in this embodiment) into the first through hole 22 formed in the band-side mounting portion 21 and the second through hole 14 formed in the main body-side band mounting portion 11 (first main body-side mounting portion 12a). This maintains the connected state of the connecting portion 60 (see Fig. 7), which is the connecting portion that connects the band-side mounting portion 21 and the main body-side band mounting portion 11 (first main body-side mounting portion 12a). Then, with the band side attachment part 21 and the body side band attachment part 11 (first body side attachment part 12a) connected by the connecting pin 5, at least one side of the connecting part (connecting part 60) where the connecting pin 5 is inserted is covered by the cover part 32, so that the connecting pin 5 is held in place so that it does not come loose.

このように本実施形態では、本体側バンド取付け部１１（特に第１の本体側取付け部１２ａ）と、バンド側取付け部２１と、連結ピン５と、カバー部３２とを含んでバンド取付け装置６（図７参照）が構成されている。
以下、バンド取付け装置６を構成する各構成部、及びバンド取付け装置６を備える時計１００（装着機器）について詳説する。 In this manner, in this embodiment, the band mounting device 6 (see Figure 7) is configured to include the body side band mounting portion 11 (particularly the first body side mounting portion 12a), the band side mounting portion 21, the connecting pin 5, and the cover portion 32.
Below, each component that makes up the band attachment device 6 and the watch 100 (wearing device) that is equipped with the band attachment device 6 will be described in detail.

［構成］
まず時計本体１０を構成する本体ケース１は、中空の短柱形状に形成されている。
本体ケース１を形成する材料は特に限定されないが、例えばポリアリレート（ＰＡＲ）等のスーパーエンジニアリング・プラスチックやポリアセタール（ＰＯＭ）等のエンジニアリング・プラスチック等の硬質の合成樹脂又はチタンやステンレス鋼（ＳＵＳ）等の金属等の硬質材料で形成されている。
図示はしないが、本体ケース１の内部には、時計モジュールが設けられている。時計モジュールは、例えば指針を運針させて時刻を指示する時計ムーブメント、時刻等の情報を表示する表示部、これらを駆動して制御する回路部等、時計機能に必要な各種の部品を含んでいる。 [composition]
First, a main body case 1 constituting a watch main body 10 is formed in a hollow short column shape.
The material from which the main body case 1 is formed is not particularly limited, but it is formed from a hard material such as a hard synthetic resin, such as a super engineering plastic such as polyarylate (PAR) or an engineering plastic such as polyacetal (POM), or a metal, such as titanium or stainless steel (SUS).
Although not shown, a clock module is provided inside the main body case 1. The clock module includes various parts necessary for clock functions, such as a clock movement that moves hands to indicate the time, a display unit that displays information such as the time, and a circuit unit that drives and controls these.

図３は、本体ケースとバンドとが連結される様子を示す要部斜視図である。
図３に示すように、本体ケース１の外側部であってアナログ方式の時計における６時側及び図示は省略するが１２時側に対応する位置には、それぞれ本体ケース１にバンド２を連結させるための本体側バンド取付け部１１が設けられている。
本体側バンド取付け部１１は、バンド２の連結時に連結ピン５が挿入される一方側（図３においてｘ方向の右側、アナログ方式の時計における３時側、なお１２時側に位置する本体側バンド取付け部１１の場合には９時側）に設けられた第１の本体側取付け部１２ａと、バンド２の連結時においてバンド２に設けられた後述するバンド側取付け部２１を挟んで他方側（図３においてｘ方向の左側、アナログ方式の時計における９時側、なお１２時側に位置する本体側バンド取付け部１１の場合には３時側）に設けられた第２の本体側取付け部１２ｂと、を含んでいる。 FIG. 3 is a perspective view of the essential parts, showing how the main case and the band are connected to each other.
As shown in FIG. 3, on the outer side of the main case 1, at positions corresponding to the 6 o'clock side of an analog watch and to the 12 o'clock side (not shown), there are provided main case band attachment portions 11 for connecting the band 2 to the main case 1.
The body-side band attachment portion 11 includes a first body-side attachment portion 12a provided on one side (the right side in the x direction in FIG. 3, the 3 o'clock side in an analog watch, or the 9 o'clock side in the case of the body-side band attachment portion 11 located on the 12 o'clock side) where the connecting pin 5 is inserted when the band 2 is connected, and a second body-side attachment portion 12b provided on the other side (the left side in the x direction in FIG. 3, the 9 o'clock side in an analog watch, or the 3 o'clock side in the case of the body-side band attachment portion 11 located on the 12 o'clock side) across a band-side attachment portion 21 described later provided on the band 2 when the band 2 is connected.

第１の本体側取付け部１２ａ及び第２の本体側取付け部１２ｂは、本体ケース１の外方に突出する左右一対の脚部である。第１の本体側取付け部１２ａと第２の本体側取付け部１２ｂとの間は、バンド側取付け部２１を受け入れる受入れ凹部１３となっている。
本体側バンド取付け部１１のうち、連結ピン５が挿入される側である一方側（図１～図３においてｘ方向右側）に設けられている第１の本体側取付け部１２ａには、時計１００の幅方向（Ｘ方向、図３に示す３時－９時方向）に貫通する第２の貫通孔１４が形成されている。 The first body side mounting portion 12a and the second body side mounting portion 12b are a pair of left and right legs that protrude outward from the main body case 1. A receiving recess 13 that receives the band side mounting portion 21 is formed between the first body side mounting portion 12a and the second body side mounting portion 12b.
Of the body side band attachment portion 11, the first body side attachment portion 12a is provided on one side (the right side in the x direction in Figures 1 to 3) where the connecting pin 5 is inserted, and is formed with a second through hole 14 that penetrates in the width direction of the watch 100 (X direction, the 3 o'clock to 9 o'clock direction shown in Figure 3).

本実施形態では、本体側バンド取付け部１１の受入れ凹部１３内にバンド側取付け部２１を配置することで、本体側バンド取付け部１１とバンド側取付け部２１との連結部分である連結部６０が形成される。そして、後述する本体側バンド取付け部１１に形成された貫通孔（第２の貫通孔１４）及びバンド側取付け部２１に形成された貫通孔（第１の貫通孔２２）に一方側（図１～図３においてｘ方向右側）から連結ピン５を挿入することで、この連結部６０における連結状態が維持される。
なお、連結ピン５を連結部６０の右側から挿入する構成とすることで、特にユーザが右利きの場合に連結作業がしやすくなる。 In this embodiment, a connecting portion 60 is formed as a connecting portion between the main body side band mounting portion 11 and the band side mounting portion 21 by arranging the band side mounting portion 21 in the receiving recess 13 of the main body side band mounting portion 11. Then, the connecting pin 5 is inserted from one side (the right side in the x direction in FIGS. 1 to 3 ) into a through hole (second through hole 14) formed in the main body side band mounting portion 11 and a through hole (first through hole 22) formed in the band side mounting portion 21, which will be described later, to maintain the connected state at this connecting portion 60.
Incidentally, by configuring the connecting pin 5 to be inserted from the right side of the connecting portion 60, the connecting operation becomes easier, particularly for right-handed users.

また、本体側バンド取付け部１１のうち、受入れ凹部１３に受け入れられたバンド側取付け部２１を挟んで他方側（図１～図３においてｘ方向左側）に設けられている第２の本体側取付け部１２ｂにおける内側の面（受入れ凹部１３側の面）であって、第１の本体側取付け部１２ａの第２の貫通孔１４に対応する位置には、他方側（図１～図３においてｘ方向左側）に貫通しない穴である凹部１５が形成されている。 The second body-side mounting part 12b, which is provided on the other side (the left side in the x-direction in Figs. 1 to 3) of the body-side band mounting part 11 and sandwiches the band-side mounting part 21 received in the receiving recess 13, has a recess 15, which is a hole that does not penetrate to the other side (the left side in the x-direction in Figs. 1 to 3), formed on its inner surface (the surface on the receiving recess 13 side) at a position corresponding to the second through-hole 14 of the first body-side mounting part 12a.

図４は、本体ケースとバンドとの連結部分に連結ピンを取り付ける様子を示す要部斜視図である。
図４等に示すように、第２の貫通孔１４は、連結ピン５が挿入される一方側（図１～図４においてｘ方向右側）の開口端部分を第１径部１４１としたときに、この第１径部１４１に連続して形成された第２径部１４２の内径が、第１径部１４１の内径よりも小さくなっている。そして、第１径部１４１と第２径部１４２との境界には、段部１４３が形成されている。 FIG. 4 is a perspective view of the essential parts, showing how a connecting pin is attached to the connecting portion between the main case and the band.
4 and other figures, when the open end portion of the second through hole 14 on one side (the right side in the x direction in FIGS. 1 to 4) where the connecting pin 5 is inserted is defined as a first diameter portion 141, the inner diameter of a second diameter portion 142 formed contiguous to this first diameter portion 141 is smaller than the inner diameter of the first diameter portion 141. A step portion 143 is formed at the boundary between the first diameter portion 141 and the second diameter portion 142.

後述するように第２の貫通孔１４に挿入される連結ピン５は、ピン頭部５１と、ピン頭部５１よりも径の小さい軸部５２とを有し、ピン頭部５１と軸部５２との境界部分に当接面５１３を有している。連結ピン５が一方側から挿入された際、連結ピン５の当接面５１３が段部１４３に突き当てられて位置決めされる。このように、段部１４３は連結ピン５の当接面５１３を受ける受け面として機能する。 As described below, the connecting pin 5 inserted into the second through hole 14 has a pin head 51 and a shaft portion 52 with a smaller diameter than the pin head 51, and has an abutment surface 513 at the boundary between the pin head 51 and the shaft portion 52. When the connecting pin 5 is inserted from one side, the abutment surface 513 of the connecting pin 5 abuts against the step portion 143 and is positioned. In this way, the step portion 143 functions as a receiving surface that receives the abutment surface 513 of the connecting pin 5.

連結ピン５を精度高く位置決めするために、段部１４３は硬質な材料で形成されている本体ケース１の本体側バンド取付け部１１に設けられることが好ましく、ピン頭部５１からあまり離れない位置である第１の本体側取付け部１２ａ内に設けられることがさらに好ましい。なお、段部１４３を設ける位置は図示例に限定されない。また、受け面として機能するのは段部１４３に限定されない。例えば連結ピン５の軸部５２の先端部分の端面を当接面とし、第２の本体側取付け部１２ｂにおける凹部１５がこの当接面を受ける受け面として機能してもよい。この場合には第２の貫通孔１４の途中に段部１４３を設ける必要がない。 In order to position the connecting pin 5 with high precision, the step 143 is preferably provided in the main body side band mounting portion 11 of the main body case 1, which is made of a hard material, and more preferably in the first main body side mounting portion 12a, which is located not far from the pin head portion 51. The position where the step 143 is provided is not limited to the illustrated example. The step 143 is not limited to function as a receiving surface. For example, the end face of the tip portion of the shaft portion 52 of the connecting pin 5 may be used as an abutment surface, and the recess 15 in the second main body side mounting portion 12b may function as a receiving surface that receives this abutment surface. In this case, there is no need to provide the step 143 in the middle of the second through hole 14.

第１の本体側取付け部１２ａ及び第２の本体側取付け部１２ｂにおける外側の面には、外装部材である後述するベゼル部材３に係止される係止凸部１６が形成されている。係止凸部１６はベゼル部材３に設けられる後述の係止凹部３２２（図５参照）に係止されるものであり、係止凸部１６の位置や形状、大きさ等はベゼル部材３の係止凹部３２２の位置や形状、大きさ等に対応するものが設けられる。本実施形態において係止凸部１６は、図４等に示すように、下に向って広がる形状の係止爪となっている。 A locking protrusion 16 is formed on the outer surface of the first body side mounting portion 12a and the second body side mounting portion 12b to be locked to the bezel member 3, which is an exterior member and will be described later. The locking protrusion 16 is locked to a locking recess 322 (see FIG. 5) provided on the bezel member 3, which will be described later, and the position, shape, size, etc. of the locking protrusion 16 correspond to the position, shape, size, etc. of the locking recess 322 of the bezel member 3. In this embodiment, the locking protrusion 16 is a locking claw that widens downward, as shown in FIG. 4, etc.

また時計本体１０を構成するベゼル部材３は、例えばポリウレタン(ＰＵＲ；polyurethane)等の柔軟性のある合成樹脂により形成されている。なお、ベゼル部材３を形成する材料はこれに限定されない。部分ごとに異なる材料で形成されたものであってもよい。
図５は、図２における矢視V方向から見たベゼル部材の要部斜視図である。
図５に示すように、ベゼル部材３は、少なくとも本体ケース１の視認側の外周縁を覆うように配置されるベゼル本体３１と、ベゼル本体３１におけるｙ方向の両端側（すなわちアナログ時計における６時側及び１２時側）にそれぞれ連設された一対のカバー部３２とを有している。 The bezel member 3 constituting the watch body 10 is made of a flexible synthetic resin such as polyurethane (PUR). Note that the material from which the bezel member 3 is made is not limited to this. Each part of the bezel member 3 may be made of a different material.
5 is a perspective view of a main part of the bezel member as viewed in the direction of the arrow V in FIG. 2. FIG.
As shown in Figure 5, the bezel member 3 has a bezel main body 31 that is arranged to cover at least the outer peripheral edge of the viewing side of the main case 1, and a pair of cover portions 32 that are respectively connected to both ends of the bezel main body 31 in the y direction (i.e., the 6 o'clock side and the 12 o'clock side on an analog watch).

図１等に示すように、本実施形態におけるベゼル本体３１は、本体ケース１の視認側の外周縁から本体ケース１の側面までを覆う形状となっている。
またカバー部３２は、バンド側取付け部２１及び本体側バンド取付け部１１を連結させた状態で、連結部分（すなわち、連結部６０）のうち少なくとも連結ピン５が挿入される一方側（図１～図４においてｘ方向右側）を覆うものである。本実施形態におけるカバー部３２は、ほぼコ字状に形成されており、連結部６０の上面と一方側（図１～図４においてｘ方向右側）の側面及び他方側（図１～図４においてｘ方向左側）の側面とを覆っている。 As shown in FIG. 1 and other figures, the bezel body 31 in this embodiment has a shape that covers from the outer peripheral edge of the main body case 1 on the viewing side to the side surface of the main body case 1 .
Furthermore, the cover portion 32 covers at least one side (the right side in the x-direction in FIGS. 1 to 4) of the connecting portion (i.e., connecting portion 60) into which the connecting pin 5 is inserted when the band side mounting portion 21 and the main body side band mounting portion 11 are connected. The cover portion 32 in this embodiment is formed in a substantially U-shape, and covers the top surface and the side surface on one side (the right side in the x-direction in FIGS. 1 to 4) and the side surface on the other side (the left side in the x-direction in FIGS. 1 to 4) of the connecting portion 60.

カバー部３２において連結部６０の一方側（図１～図４においてｘ方向右側）の側面を覆う部分の内側面には、収容凹部３２１が形成されている。収容凹部３２１は、第１の貫通孔２２及び第２の貫通孔１４に連結ピン５が挿入された際に、連結ピン５のピン頭部５１（図６参照）に対応する位置に設けられ、ピン頭部５１（少なくともピン頭部５１の鍔部５１１）を収めることのできるものである。 A storage recess 321 is formed on the inner surface of the portion of the cover 32 that covers one side of the side of the connecting portion 60 (the right side in the x direction in Figs. 1 to 4). The storage recess 321 is provided at a position corresponding to the pin head 51 (see Fig. 6) of the connecting pin 5 when the connecting pin 5 is inserted into the first through hole 22 and the second through hole 14, and is capable of storing the pin head 51 (at least the flange portion 511 of the pin head 51).

例えば図２に示すように連結部６０の上方からカバー部３２を被せて、収容凹部３２１内にピン頭部５１（少なくともピン頭部５１の鍔部５１１）を配置させるとカバー部３２によって連結ピン５のピン頭部５１側が押さえられ、連結ピン５が第１の貫通孔２２及び第２の貫通孔１４から抜けるのを防ぐことができる。
なお、収容凹部３２１は、できるだけピン頭部５１のうち、連結部６０の側部から外部に突出している部分（本実施形態ではピン頭部５１の鍔部５１１）の形状に沿う形状、大きさのものであることが好ましい。これにより、カバー部３２の本体ケース1への密着性が向上し、カバー部３２が連結部６０から浮き上がりにくく、外れにくい構成とすることができる。 For example, as shown in Figure 2, when the cover portion 32 is placed from above the connecting portion 60 and the pin head 51 (at least the flange portion 511 of the pin head 51) is positioned within the accommodating recess 321, the pin head 51 side of the connecting pin 5 is pressed down by the cover portion 32, thereby preventing the connecting pin 5 from slipping out of the first through hole 22 and the second through hole 14.
Incidentally, it is preferable that the accommodating recess 321 has a shape and size that conforms as closely as possible to the shape of the portion of the pin head 51 that protrudes outward from the side of the connecting portion 60 (in this embodiment, the flange portion 511 of the pin head 51). This improves the adhesion of the cover portion 32 to the main body case 1, making it difficult for the cover portion 32 to float up from the connecting portion 60 and become detached.

また前述のように、本実施形態において連結部６０の外側面となる本体ケース１の本体側バンド取付け部１１の外側面（第１の本体側取付け部１２ａの右側面及び第２の本体側取付け部１２ｂの左側面）には、爪状の係止凸部１６（図４等参照）が設けられており、カバー部３２において連結部６０の一方側（図１～図４においてｘ方向右側）の側面及び他方側（図１～図４においてｘ方向左側）の側面を覆う部分の内側面には、本体ケース１の係止凸部１６に対応する位置に、係止凸部１６の形状等に対応する形状の係止凹部３２２（図５参照）が形成されている。なお係止凸部１６が連結部６０の一方側及び他方側の両外側面に設けられていることは必須ではない。例えば連結ピン５のピン頭部５１が突出している連結部６０の一方側にだけ係止凸部１６が設けられていてもよい。この場合にはカバー部３２の係止凹部３２２も係止凸部１６に対応する位置にだけ設ければよい。 As described above, the outer surface of the main body side band attachment portion 11 of the main body case 1, which is the outer surface of the connecting portion 60 in this embodiment (the right side surface of the first main body side attachment portion 12a and the left side surface of the second main body side attachment portion 12b), is provided with a claw-shaped locking protrusion 16 (see FIG. 4, etc.), and the inner surface of the portion of the cover portion 32 that covers the side surface on one side (the right side in the x direction in FIGS. 1 to 4) and the other side (the left side in the x direction in FIGS. 1 to 4) of the connecting portion 60 is formed with a locking recess 322 (see FIG. 5) having a shape corresponding to the shape of the locking protrusion 16 at a position corresponding to the locking protrusion 16 of the main body case 1. Note that it is not essential that the locking protrusion 16 is provided on both the outer surfaces of the connecting portion 60 on one side and the other side. For example, the locking protrusion 16 may be provided only on one side of the connecting portion 60 from which the pin head 51 of the connecting pin 5 protrudes. In this case, the locking recess 322 of the cover part 32 only needs to be provided at a position corresponding to the locking protrusion 16.

係止凸部１６がベゼル部材３のカバー部３２に形成されている係止凹部３２２に係止されると、カバー部３２がより強く本体ケース1側に密着し、カバー部３２が捲れたり外れたりしにくくなる。
なお、カバー部３２及び本体ケース１のいずれかに係止凸部を設け、本体ケース１及びカバー部３２のいずれかに係止凸部を係止させる係止凹部が形成されていればよく、係止凸部がカバー部３２側に設けられ、本体ケース１側にこれを受ける形状の係止凹部が設けられていてもよい。 When the locking protrusion 16 is locked in the locking recess 322 formed in the cover portion 32 of the bezel member 3, the cover portion 32 adheres more firmly to the main case 1 side, making the cover portion 32 less likely to be turned up or come off.
In addition, it is sufficient that a locking protrusion is provided on either the cover part 32 or the main body case 1, and a locking recess is formed on either the main body case 1 or the cover part 32 to lock the locking protrusion, or the locking protrusion may be provided on the cover part 32 side, and a locking recess shaped to receive it may be provided on the main body case 1 side.

図４等に示すように本実施形態では、本体ケース１の本体側バンド取付け部１１のうち、第１の本体側取付け部１２ａの外側面であって、連結ピン５の挿入される第２の貫通孔１４が開口している近傍位置に係止凸部１６が設けられている。
連結ピン５の挿入位置に近い部分でカバー部３２を本体ケース１に係止させることにより、カバー部３２が連結ピン５のピン頭部５１を押さえつける押さえつけ力も向上する。 As shown in Figure 4 etc., in this embodiment, a locking protrusion 16 is provided on the outer surface of the first body side mounting portion 12a of the body side band mounting portion 11 of the main body case 1, in a position near where the second through hole 14 through which the connecting pin 5 is inserted is opened.
By engaging the cover portion 32 with the main case 1 at a portion close to the insertion position of the connecting pin 5, the pressing force with which the cover portion 32 presses the pin head portion 51 of the connecting pin 5 is also improved.

図６は、本実施形態の連結ピンを示す斜視図である。
図６に示すように、連結ピン５は、ピン頭部５１と、ピン頭部５１に連設される軸部５２とを有している。
連結ピン５は、例えばステンレス鋼（ＳＵＳ）等の金属で形成されている。なお、連結ピン５を形成する材料はこれに限定されない。 FIG. 6 is a perspective view showing the connecting pin of the present embodiment.
As shown in FIG. 6 , the connecting pin 5 has a pin head portion 51 and a shaft portion 52 connected to the pin head portion 51 .
The connecting pin 5 is made of a metal such as stainless steel (SUS), but the material for forming the connecting pin 5 is not limited to this.

ピン頭部５１は、軸部５２よりも径の大きな部分であり、連結ピン５を第１の貫通孔２２及び第２の貫通孔１４に挿入したとき、少なくともピン頭部５１の一部が連結部６０の側部から外部に突出する。この外部に突出する部分が前述の収容凹部３２１内に収容される鍔部５１１である。鍔部５１１に連設される部分は、頭部本体５１２となっている。頭部本体５１２の径は第１の本体側取付け部１２ａの第２の貫通孔１４における第１径部１４１の内径に対応する径となっている。 The pin head 51 is a portion having a larger diameter than the shaft portion 52, and when the connecting pin 5 is inserted into the first through hole 22 and the second through hole 14, at least a portion of the pin head 51 protrudes outward from the side of the connecting portion 60. This protruding portion is the flange portion 511 that is housed in the aforementioned housing recess 321. The portion connected to the flange portion 511 is the head body 512. The diameter of the head body 512 corresponds to the inner diameter of the first diameter portion 141 in the second through hole 14 of the first body side mounting portion 12a.

ピン頭部５１における連結部６０の一方側の外側面（すなわち第１の本体側取付け部１２ａの外側面）に対向する面は、周方向の少なくとも一部に連結部６０から離れる方向に傾斜する傾斜面５１４を有している。本実施形態では、鍔部５１１における挿入側の面が連結ピン５の周方向の全周に亘ってテーパ状に傾斜しており、このテーパ面が傾斜面５１４となる。本体ケース１とバンド２との連結状態において、傾斜面５１４と連結部６０の外側面との間には隙間が形成される（図７及び図８参照）。 The surface of the pin head 51 facing the outer surface of one side of the connecting portion 60 (i.e., the outer surface of the first body-side mounting portion 12a) has an inclined surface 514 that is inclined in a direction away from the connecting portion 60 in at least a portion of the circumferential direction. In this embodiment, the insertion side surface of the flange portion 511 is inclined in a tapered manner around the entire circumferential direction of the connecting pin 5, and this tapered surface becomes the inclined surface 514. When the main body case 1 and the band 2 are connected, a gap is formed between the inclined surface 514 and the outer surface of the connecting portion 60 (see Figures 7 and 8).

軸部５２は、連結時に連結部６０内に挿入され、挿入状態においてその先端部分が第２の本体側取付け部１２ｂの凹部１５内に配置される。
軸部５２の径は、ピン頭部５１の頭部本体５１２よりも径が小さく、第１の本体側取付け部１２ａの第２の貫通孔１４における第２径部１４２の内径に対応する径となっている。
頭部本体５１２と軸部５２との境界部分は当接面となっており、連結ピン５を第２の貫通孔１４内に挿入した際に受け面である段部１４３に突き当たり、位置決めされる。 The shaft portion 52 is inserted into the connecting portion 60 when connected, and in the inserted state, its tip portion is disposed in the recess 15 of the second main body side mounting portion 12b.
The diameter of the shaft portion 52 is smaller than the diameter of the head body 512 of the pin head portion 51 and corresponds to the inner diameter of the second diameter portion 142 in the second through hole 14 of the first body side mounting portion 12a.
The boundary between the head body 512 and the shaft portion 52 forms an abutment surface, and when the connecting pin 5 is inserted into the second through-hole 14, it abuts against the step portion 143 which is a receiving surface, and is positioned.

本実施形態においてバンド２は、例えばポリウレタン(ＰＵＲ；polyurethane)等の柔軟性のある合成樹脂、エンジニアリング・プラスチックやスーパーエンジニアリング・プラスチック等の硬質の合成樹脂で形成されている。なおバンド２を形成する材料はこれに限定されず、例えばチタンやステンレス鋼（ＳＵＳ）等の金属で形成されたものであってもよいし、各種の革等で形成されたものであってもよい。また複数種類の異素材を組み合わせて形成されたもの等であってもよい。バンド２は、各種の樹脂材料等により一つながりに形成されたものでもよいし、複数のバンド駒を連結することで所定の長さに形成されるものでもよい。
本実施形態では、バンド２が本体ケース１に対してユーザの操作により着脱可能な状態で連結されている。このため、例えば異なる材料で形成されたバンド２が複数種類用意され、ユーザが好みや状況に応じてバンド２を適宜付け替えられるようにしてもよい。 In this embodiment, the band 2 is formed of a flexible synthetic resin such as polyurethane (PUR), or a hard synthetic resin such as engineering plastic or super engineering plastic. The material forming the band 2 is not limited to these, and the band 2 may be formed of a metal such as titanium or stainless steel (SUS), or may be formed of various types of leather, or may be formed by combining multiple types of different materials. The band 2 may be formed as a single piece from various resin materials, or may be formed to a predetermined length by connecting multiple band links.
In this embodiment, the band 2 is connected to the main case 1 in a detachable state by a user operation. For this reason, for example, a plurality of types of bands 2 made of different materials may be prepared so that the user can change the band 2 as appropriate according to preference or situation.

いずれの構成の場合にも、バンド２は、本体ケース１への取り付け側端部２０に、バンド側取付け部２１を有している。図３等に示すように、バンド側取付け部２１は、本体ケース１の本体側バンド取付け部１１に形成された受入れ凹部１３内に受け入れられる凸部である。 In either configuration, the band 2 has a band-side attachment portion 21 at the attachment end 20 to the main case 1. As shown in FIG. 3, etc., the band-side attachment portion 21 is a protrusion that is received in a receiving recess 13 formed in the main case 1's main case-side band attachment portion 11.

バンド側取付け部２１は、バンド２の幅方向（図１等においてＸ方向）に貫通する第１の貫通孔２２を備えている。図２及び図３等に示すように、第１の貫通孔２２の内部にはバンドパイプ４が配置されている。バンドパイプ４は例えばステンレス鋼（ＳＵＳ）等の金属で形成されており、本体ケース１とバンド２との連結部分を補強するものである。第１の貫通孔２２内にバンドパイプ４を配置することで、バンド２と本体ケース１とが連結されている部分である連結部６０（図７参照）に対して、特にねじり方向の力が加わった際の強度を高めることができる。 The band side attachment portion 21 has a first through hole 22 that penetrates the width direction of the band 2 (X direction in FIG. 1, etc.). As shown in FIG. 2 and FIG. 3, etc., a band pipe 4 is arranged inside the first through hole 22. The band pipe 4 is made of a metal such as stainless steel (SUS), and reinforces the connection part between the main body case 1 and the band 2. By arranging the band pipe 4 inside the first through hole 22, it is possible to increase the strength of the connection part 60 (see FIG. 7), which is the part where the band 2 and the main body case 1 are connected, especially when a force in the torsional direction is applied.

［作用］
次に、本実施形態のバンド取付け装置６及びバンド取付け装置６を備える装着機器である時計１００の作用について説明する。
本体ケース１にバンド２を取り付ける際には、まず、図２に示すように、バンド２のバンド側取付け部２１内にバンドパイプ４を挿入する。そして図２及び図３に示すように、本体ケース１に形成されている本体側バンド取付け部１１における第１の本体側取付け部１２ａと第２の本体側取付け部１２ｂとの間の受入れ凹部１３内に、バンド２のバンド側取付け部２１を嵌め合わせる（図４参照）。 [Action]
Next, the operation of the band attachment device 6 of this embodiment and the watch 100, which is a wearable device equipped with the band attachment device 6, will be described.
When attaching the band 2 to the main body case 1, first, as shown in Fig. 2, the band pipe 4 is inserted into the band side attachment portion 21 of the band 2. Then, as shown in Figs. 2 and 3, the band side attachment portion 21 of the band 2 is fitted into the receiving recess 13 between the first body side attachment portion 12a and the second body side attachment portion 12b of the main body side band attachment portion 11 formed on the main body case 1 (see Fig. 4).

図４に示すように本体側バンド取付け部１１とバンド側取付け部２１とを嵌め合わせたら、両者の連結部分の一方側（ｘ方向右側、アナログ時計における３時側）から第１の貫通孔２２及び第２の貫通孔１４に連結ピン５を軸部５２側から挿入する。第１の貫通孔２２内では、連結ピン５はバンドパイプ４を介して第１の貫通孔２２内に配置される。また、軸部５２が第１の貫通孔２２及び第２の貫通孔１４に挿通されると、軸部５２の先端部分が凹部１５内に挿入される。
この状態において、第２の貫通孔１４の第２径部１４２内には連結ピン５の軸部５２が配置されるとともに、第２の貫通孔１４の第１径部１４１内には連結ピン５のピン頭部５１の頭部本体５１２が配置され、連結ピン５の当接面５１３が受け面としての第２の貫通孔１４内の段部１４３に突き当たって位置決めされる。 4, after the main body side band attachment part 11 and the band side attachment part 21 are fitted together, the connecting pin 5 is inserted from the shaft part 52 side into the first through hole 22 and the second through hole 14 from one side of the connecting part between them (the right side in the x direction, the 3 o'clock side of the analog watch). Inside the first through hole 22, the connecting pin 5 is disposed in the first through hole 22 via the band pipe 4. When the shaft part 52 is inserted into the first through hole 22 and the second through hole 14, the tip part of the shaft part 52 is inserted into the recess 15.
In this state, the shaft portion 52 of the connecting pin 5 is positioned within the second diameter portion 142 of the second through hole 14, and the head body 512 of the pin head portion 51 of the connecting pin 5 is positioned within the first diameter portion 141 of the second through hole 14, and the abutment surface 513 of the connecting pin 5 abuts against the step portion 143 in the second through hole 14, which serves as a receiving surface, and is positioned.

本体側バンド取付け部１１及びバンド側取付け部２１の連結部分である連結部６０が連結ピン５により連結されると、本体ケース１とバンド２との連結状態が維持される。
連結ピン５が第２の貫通孔１４内に位置決めされた状態では、連結ピン５のうち、ピン頭部５１の鍔部５１１だけが連結部６０の外側に配置される。そして、鍔部５１１における連結部６０の外側面と対向する側に形成されたテーパ状の傾斜面５１４と連結部６０の外側面との間には、治具や爪等を引っ掛けることができる程度の隙間が形成される。 When the connecting portion 60, which is the connecting portion between the main body side band attachment portion 11 and the band side attachment portion 21, is connected by the connecting pin 5, the connected state between the main body case 1 and the band 2 is maintained.
When the connecting pin 5 is positioned within the second through-hole 14, only the flange 511 of the pin head 51 of the connecting pin 5 is disposed outside the connecting part 60. Then, between the outer surface of the connecting part 60 and a tapered inclined surface 514 formed on the side of the flange 511 facing the outer surface of the connecting part 60, a gap large enough to hook a jig, a claw, or the like is formed.

連結部６０に連結ピン５が挿入された状態となると、本体ケース１の上（図１～図４におけるＺ方向上側）からベゼル部材３を取り付ける。これにより時計本体１０が完成する。
図７は、ベゼル部材３が取り付けられた状態の連結部６０とその周辺を示す模式的な要部断面図である。図８は、図７において一点鎖線で囲んだVIII部分の拡大断面図である。
図７に示すように、本実施形態では、カバー部３２によって連結部６０の上面及び両側面が覆われた状態となる。そしてこの状態において、図７及び図８に示すように、連結部６０の外側に突出している連結ピン５の鍔部５１１がカバー部３２の収容凹部３２１内に収容され、カバー部３２により連結ピン５が外れないように外側から押さえつけられた状態となる。 Once the connecting pin 5 is inserted into the connecting portion 60, the bezel member 3 is attached from above the main case 1 (the upper side in the Z direction in FIGS. 1 to 4). This completes the watch body 10.
Fig. 7 is a schematic cross-sectional view of a main part showing the connecting portion 60 and its periphery in a state where the bezel member 3 is attached. Fig. 8 is an enlarged cross-sectional view of a portion VIII surrounded by a dashed line in Fig. 7.
As shown in Fig. 7, in this embodiment, the top surface and both side surfaces of the connecting part 60 are covered by the cover part 32. In this state, as shown in Figs. 7 and 8, the flange part 511 of the connecting pin 5 protruding outward from the connecting part 60 is accommodated in the accommodation recess 321 of the cover part 32, and the connecting pin 5 is pressed down from the outside by the cover part 32 so as not to come off.

さらに、本実施形態では、本体側バンド取付け部１１における、連結ピン５の鍔部５１１が突出している部分の近傍に、係止凸部１６が設けられている。係止凸部１６は、ベゼル部材３のカバー部３２に形成されている係止凹部３２２に係止されるため、連結ピン５を外側から押さえている部分においてベゼル部材３（ベゼル部材３のカバー部３２）の本体ケース１への密着性が高くなる。 Furthermore, in this embodiment, a locking protrusion 16 is provided in the vicinity of the portion of the main body side band attachment portion 11 where the flange portion 511 of the connecting pin 5 protrudes. The locking protrusion 16 is locked to the locking recess 322 formed in the cover portion 32 of the bezel member 3, so that the bezel member 3 (cover portion 32 of the bezel member 3) adheres closely to the main body case 1 in the portion pressing the connecting pin 5 from the outside.

なお、バンド２を時計本体１０（時計本体１０の本体ケース１）から取り外す際には、まず、図示しないベゼル部材取外し用の治具等を用いてベゼル部材３を本体ケース１から取り外す。具体的には、例えば本体ケース１とベゼル部材３との間に治具を差し込んで、カバー部３２を含むベゼル部材３を引っ掛ける等により取り外す。
カバー部３２が本体ケース１（本体ケース１とバンド２とが連結されている部分である連結部６０）から外されると、連結ピン５の鍔部５１１が突出している部分が露出する。この状態で、連結ピン５の鍔部５１１に形成されたテーパ状の傾斜面５１４と連結部６０の外側面との間の隙間に治具や爪等を引っ掛けることにより、連結ピン５を本体側バンド取付け部１１とバンド側取付け部２１との連結部分から引き抜く。
これにより、本体ケース１とバンド２との連結が解除され、ユーザは、特別な道具等を用意しなくても、比較的容易に本体ケース１からバンド２を取り外すことができる。 When removing the band 2 from the watch body 10 (the body case 1 of the watch body 10), first, a jig for removing a bezel member (not shown) is used to remove the bezel member 3 from the body case 1. Specifically, for example, a jig is inserted between the body case 1 and the bezel member 3, and the bezel member 3 including the cover portion 32 is hooked and removed.
When the cover portion 32 is removed from the main body case 1 (the connecting portion 60 which is the portion connecting the main body case 1 and the band 2), the protruding portion of the flange portion 511 of the connecting pin 5 is exposed. In this state, by hooking a jig, a claw, or the like into the gap between the tapered inclined surface 514 formed on the flange portion 511 of the connecting pin 5 and the outer surface of the connecting portion 60, the connecting pin 5 is pulled out from the connecting portion between the main body side band attachment portion 11 and the band side attachment portion 21.
This releases the connection between the main case 1 and the band 2, allowing the user to remove the band 2 from the main case 1 relatively easily without having to prepare any special tools or the like.

［効果］
以上のように本実施形態におけるバンド取付け装置６は、バンド２に設けられ、バンド２の幅方向に貫通する第１の貫通孔２２を備えるバンド側取付け部２１と、本体ケース１に設けられ、バンド側取付け部２１を挟んで配置されて、取付け状態において第１の貫通孔２２と連通する第２の貫通孔１４を備える本体側バンド取付け部１１と、第１の貫通孔２２及び第２の貫通孔１４に一方側（本実施形態では、ｘ方向右側）から挿入され、バンド側取付け部２１と本体側バンド取付け部１１との連結部分に取り付けられる連結ピン５と、バンド側取付け部２１及び本体側バンド取付け部１１を連結させた状態で、連結部分のうち少なくとも連結ピン５が挿入される一方側を覆うカバー部３２と、を有している。
これにより、本体ケース１にバンド2を容易に固定することができる。また、カバー部３２（本実施形態では、ベゼル部材３全体）を外せば容易に本体ケース１とバンド２とを連結させている連結ピン５にアクセスすることができる。このため、専用の道具（治具）等を持っていないユーザでも、比較的容易にバンド２の付け替え等を行うことができる。
そしてこのようなバンド取付け装置６によって本体ケース１にバンド２を取り付けることで、時計１００等の装着機器において、バンド２の着脱、交換を簡易に行うことができ、例えば場所や用途に応じてバンド２を付け替え、気軽に楽しむことも可能となる。 [effect]
As described above, the band attachment device 6 in this embodiment comprises: a band side attachment portion 21 that is provided on the band 2 and has a first through hole 22 that penetrates in the width direction of the band 2; a body side band attachment portion 11 that is provided on the main body case 1 and arranged on either side of the band side attachment portion 21 and has a second through hole 14 that communicates with the first through hole 22 in the attached state; a connecting pin 5 that is inserted into the first through hole 22 and the second through hole 14 from one side (in this embodiment, the right side in the x direction) and is attached to the connecting portion between the band side attachment portion 21 and the body side band attachment portion 11; and a cover portion 32 that covers at least one side of the connecting portion into which the connecting pin 5 is inserted when the band side attachment portion 21 and the body side band attachment portion 11 are connected.
This allows the band 2 to be easily fixed to the main case 1. In addition, by removing the cover portion 32 (in this embodiment, the entire bezel member 3), it is possible to easily access the connecting pin 5 that connects the main case 1 and the band 2. Therefore, even a user who does not have a dedicated tool (jig) can relatively easily replace the band 2.
By attaching the band 2 to the main case 1 using this type of band attachment device 6, the band 2 can be easily attached, detached, and replaced in a wearable device such as a watch 100, and it can be easily enjoyed by changing the band 2 depending on the location or purpose, for example.

また、連結ピン５は、一方側（本実施形態では、ｘ方向右側）の端部に、連結部６０よりも外方に突出するピン頭部５１（ピン頭部５１の鍔部５１１）を有し、カバー部３２は、少なくともこの突出部分（ピン頭部５１の鍔部５１１を覆っている。
これにより、カバー部３２を取り付けた状態では連結ピン５が抜けることが防止される。このため、本体ケース１とバンド２との連結状態を簡易な構成で維持させることができる。 The connecting pin 5 has a pin head portion 51 (a flange portion 511 of the pin head portion 51) at an end portion on one side (the right side in the x direction in this embodiment) that protrudes outward beyond the connecting portion 60, and the cover portion 32 covers at least this protruding portion (the flange portion 511 of the pin head portion 51.
This prevents the connecting pin 5 from coming loose when the cover portion 32 is attached, and therefore the connected state between the main case 1 and the band 2 can be maintained with a simple structure.

また、ピン頭部５１における連結部６０に対向する面は、周方向の少なくとも一部（本実施形態では軸周りの全周）に連結部６０から離れる方向に傾斜する傾斜面５１４を有し、傾斜面５１４と連結部６０との間に隙間が形成されている。
これにより、隙間に治具や爪を引っ掛けることができ、連結ピン５を連結部６０から引っ張り出すことができる。このため、容易に本体ケース１とバンド２との連結状態を容易に解除することができる。 In addition, the surface of the pin head 51 facing the connecting portion 60 has an inclined surface 514 that inclines in a direction away from the connecting portion 60 over at least a portion of the circumferential direction (the entire circumference around the axis in this embodiment), and a gap is formed between the inclined surface 514 and the connecting portion 60.
This allows a jig or a claw to be hooked into the gap, and the connecting pin 5 can be pulled out from the connecting portion 60. Therefore, the connected state between the main case 1 and the band 2 can be easily released.

また、第２の貫通孔１４は、連結ピン５が挿入される一方側（本実施形態では、ｘ方向右側）の第１径部１４１と、第１径部１４１に連続して形成され記第１径部１４１の内径よりも内径の小さい第２径部１４２と、第１径部１４１と第２径部１４２との境界に形成された段部１４３と、を有しており、連結ピン５は、段部１４３に当接する当接面５１３を有し、段部１４３は、連結ピン５の当接面５１３を受ける受け面として機能する。
これにより、比較的硬質な材料で形成されている本体側バンド取付け部１１内において連結ピン５を受けて、高精度に位置決めすることができる。 In addition, the second through hole 14 has a first diameter portion 141 on one side (in this embodiment, the right side in the x-direction) into which the connecting pin 5 is inserted, a second diameter portion 142 formed continuously with the first diameter portion 141 and having an inner diameter smaller than the inner diameter of the first diameter portion 141, and a step portion 143 formed at the boundary between the first diameter portion 141 and the second diameter portion 142, and the connecting pin 5 has an abutment surface 513 that abuts against the step portion 143, and the step portion 143 functions as a receiving surface that receives the abutment surface 513 of the connecting pin 5.
This allows the connecting pin 5 to be received within the main body side band attachment portion 11, which is made of a relatively hard material, and can be positioned with high precision.

また、バンド側取付け部２１の第１の貫通孔２２内に配置されるバンドパイプ４をさらに有し、連結ピン５はバンドパイプ４を介して第１の貫通孔２２内に配置される。
バンド２はバンド側取付け部２１を含めて、例えばポリウレタン(ＰＵＲ；polyurethane)等の柔軟性のある合成樹脂等で形成されている。このため比較的強度が低く、本体ケース１とバンド２との連結部分では特にねじり方向の力が加わった際の強度を高める必要がある。
この点、金属等で形成されたバンドパイプ４を第１の貫通孔２２内に配置することで、本体ケース１との連結部分を補強することができる。 The band pipe 4 is further disposed in the first through hole 22 of the band side attachment portion 21 , and the connecting pin 5 is disposed in the first through hole 22 via the band pipe 4 .
The band 2, including the band side attachment portion 21, is made of a flexible synthetic resin such as polyurethane (PUR), etc. For this reason, its strength is relatively low, and it is necessary to increase the strength of the connecting portion between the main case 1 and the band 2, especially when a torsional force is applied.
In this regard, by disposing a band pipe 4 made of metal or the like in the first through hole 22, the connection portion with the main case 1 can be reinforced.

また、本体側バンド取付け部１１は、連結ピン５が挿入される一方側（本実施形態では、ｘ方向右側）に設けられた第１の本体側取付け部１２ａと、バンド側取付け部２１を挟んで他方側に設けられた第２の本体側取付け部１２ｂと、を含み、第２の貫通孔１４は第１の本体側取付け部１２ａに形成され、第２の本体側取付け部１２ｂには、他方側に貫通しない凹部１５が形成されている。
連結ピン５を挿入する孔を連結部６０の一方側にだけ開口させ、他方側を閉塞することにより、ユーザにとって連結ピン５を挿入する向きが分かりやすく、誤って逆側から挿入しようとすることを防止することができる。 In addition, the body side band mounting portion 11 includes a first body side mounting portion 12a provided on one side (in this embodiment, the right side in the x direction) where the connecting pin 5 is inserted, and a second body side mounting portion 12b provided on the other side across the band side mounting portion 21, and a second through hole 14 is formed in the first body side mounting portion 12a, and a recess 15 that does not penetrate to the other side is formed in the second body side mounting portion 12b.
By opening the hole for inserting the connecting pin 5 only on one side of the connecting portion 60 and blocking the other side, it is easy for the user to understand the direction in which to insert the connecting pin 5, and it is possible to prevent the user from accidentally inserting it from the opposite side.

また、本実施形態のカバー部３２は、本体ケース１の視認側に配置される外装部材（本実施形態では、ベゼル本体３１）と一体的に形成されている。
バンド取付け装置を構成するカバー部３２を外装部材と一体に形成することで、部品点数を少なくすることができ、構成を簡易なものとすることができる。 Moreover, the cover portion 32 in this embodiment is formed integrally with an exterior member (in this embodiment, the bezel main body 31 ) that is arranged on the visible side of the main case 1 .
By forming the cover portion 32 constituting the band attachment device integrally with the exterior member, the number of parts can be reduced and the structure can be simplified.

［変形例］
なお、以上本発明の実施形態について説明したが、本発明は、かかる実施形態に限定されず、その要旨を逸脱しない範囲で、種々変形が可能であることは言うまでもない。 [Modification]
Although the embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to such an embodiment, and various modifications are possible without departing from the gist of the present invention.

例えば本実施形態では、連結ピン５がピン頭部５１から軸部５２まで金属材料等で一体的に形成させている場合を例示したが、連結ピンの構成はこれに限定されない。
例えば図９に示すように、金属材料等で形成された軸部５２に、各種樹脂等で形成されたピン頭部５３を取り付けて一体化させた連結ピン５ａであってもよい。ピン頭部５３を形成する材料は特に限定されないが、例えばポリウレタン(ＰＵＲ；polyurethane)等が適用される。
なお、ピン頭部５３と軸部５２とは別個に形成してから軸部５２にピン頭部５３を取り付けて一体化させてもよいし、金属材料と合成樹脂との異素材を一体成型することで一体化されたものであってもよい。 For example, in the present embodiment, the connecting pin 5 is integrally formed from the pin head portion 51 to the shaft portion 52 using a metal material or the like, but the configuration of the connecting pin is not limited to this.
9, a connecting pin 5a may be used in which a pin head 53 made of various resins or the like is attached to a shaft 52 made of a metal material or the like to form an integrated structure. The material from which the pin head 53 is made is not particularly limited, but polyurethane (PUR) or the like is used, for example.
In addition, the pin head 53 and the shaft portion 52 may be formed separately and then integrated by attaching the pin head 53 to the shaft portion 52, or they may be integrated by integrally molding different materials, such as a metal material and a synthetic resin.

図１０は、図９に示す連結ピンを用いて本体ケースとバンドとを一体化させた場合のバンド取付け装置及びその周辺の模式的な要部断面図である。
図１０に示すように、この場合も、連結ピン５ａのうち、ピン頭部５３の一部が連結部６０の外側に突出する。そして、この突出部分がカバー部３２に形成された収容凹部３２１内に収容される。 FIG. 10 is a schematic cross-sectional view of the essential parts of a band attachment device and its periphery when the main case and the band are integrated using the connecting pin shown in FIG.
10, in this case as well, a part of the pin head 53 of the connecting pin 5a protrudes outside the connecting portion 60. This protruding portion is accommodated in the accommodation recess 321 formed in the cover portion 32.

この構成では、収容凹部３２１内に収容されるピン頭部５３がポリウレタン等の樹脂で形成されているため、カバー部３２の着脱を繰り返してもカバー部３２に傷が付きにくい。例えばカバー部３２が透明又は半透明の材料で形成されるデザインであるような場合、収容凹部３２１内等に傷が付くと目立ってしまい好ましくない。
この点、ピン頭部５３が樹脂で形成されている場合には、収容凹部３２１が傷つくのを防ぐことができる。また、ピン頭部５３に鮮やかな色合いの樹脂等を採用することで、挿し色としてデザインを楽しむこともできる。 In this configuration, since the pin head 53 accommodated in the accommodation recess 321 is made of a resin such as polyurethane, the cover part 32 is less likely to be scratched even if the cover part 32 is repeatedly attached and detached. For example, if the cover part 32 is designed to be made of a transparent or translucent material, scratches inside the accommodation recess 321, etc., are noticeable, which is not preferable.
In this regard, when the pin head 53 is made of resin, it is possible to prevent damage to the accommodation recess 321. In addition, by using a brightly colored resin or the like for the pin head 53, it is possible to enjoy the design by adding an accent color.

なお、この場合、ピン頭部５３と軸部５２との境界の面５３３が、第２の貫通孔１４の段部１４３に当接する当接面となり、段部１４３が当該面５３３を受ける受け面として機能する。
なお、この場合にも連結部６０の外側面との間に隙間を形成するような傾斜面を備えてもよい。 In this case, the boundary surface 533 between the pin head 53 and the shaft 52 serves as an abutment surface that abuts against the step 143 of the second through hole 14 , and the step 143 functions as a receiving surface that receives the surface 533 .
In this case, too, an inclined surface may be provided so as to form a gap between the outer surface of the connecting portion 60 and the inclined surface.

また傾斜面を備える代わりに、又は傾斜面を備えるとともに、バンド側取付け部２１を挟んで第１の本体側取付け部１２ａとは反対の「他方側」（本実施形態では、ｘ方向左側）に設けられた第２の本体側取付け部１２ｂに、第１の貫通孔２２及び第２の貫通孔１４と連通し「他方側」に貫通する第３の貫通孔１７が形成されてもよい（図１０参照）。
「他方側」に貫通する第３の貫通孔１７を設けることで、連結ピン５ａを連結部６０から外す場合には、例えば「他方側」の貫通孔（第３の貫通孔１７）の開口部から針金状のものを挿入し、連結ピン５ａを軸部５２の先端側から押し出すことが可能となる。この場合にはピン頭部の側に傾斜面を設けて連結部６０との間に治具や爪を引っ掛ける隙間を確保する必要がない。例えばピン頭部５３がポリウレタン等の樹脂で形成されている場合、治具等によってピン頭部５３を引っ掛ける構成としないことで、ピン頭部５３が治具等で傷つくのを防ぐことができる。 In addition to or instead of providing an inclined surface, a third through hole 17 that communicates with the first through hole 22 and the second through hole 14 and penetrates to the "other side" may be formed in the second body side mounting portion 12b, which is provided on the "other side" (in this embodiment, the left side in the x-direction) opposite the first body side mounting portion 12a across the band side mounting portion 21 (see Figure 10).
By providing the third through hole 17 penetrating to the "other side", when removing the connecting pin 5a from the connecting part 60, for example, a wire-like object can be inserted from the opening of the through hole (third through hole 17) on the "other side" and the connecting pin 5a can be pushed out from the tip side of the shaft part 52. In this case, it is not necessary to provide an inclined surface on the pin head side to ensure a gap between the connecting part 60 and a jig or claw to hook it. For example, when the pin head 53 is made of a resin such as polyurethane, the pin head 53 can be prevented from being damaged by the jig or the like by not configuring the pin head 53 to be hooked by the jig or the like.

さらに、ピン頭部５１に図７に示すような傾斜面５１４を備える構成とした場合でも、図１０に示したような第１の貫通孔２２及び第２の貫通孔１４と連通し「他方側」に貫通する第３の貫通孔を、第２の本体側取付け部１２ｂに形成してもよい。この場合には、連結ピンを取り外す際、連結ピンと連結部６０との間に治具や爪を引っ掛けて、ピン頭部側から引き出してもよいし、第３の貫通孔から針金等を挿入して軸部５２の先端側から押し出してもよく、ユーザのやりやすい手法で取り出せばよい。 Even if the pin head 51 is configured to have an inclined surface 514 as shown in FIG. 7, a third through hole that communicates with the first through hole 22 and the second through hole 14 as shown in FIG. 10 and penetrates to the "other side" may be formed in the second body side mounting portion 12b. In this case, when removing the connecting pin, a jig or claw may be hooked between the connecting pin and the connecting portion 60 and pulled out from the pin head side, or a wire or the like may be inserted through the third through hole and pushed out from the tip side of the shaft portion 52, and the user may remove it by any method that is easy for them.

また、本実施形態では、カバー部３２が本体ケース１の視認側に配置される外装部材（本実施形態では、ベゼル本体３１）と一体的に形成されている場合を例示したが、カバー部の構成はこれに限定されない。
例えば図１１に示すように本体ケース１の視認側に配置される外装部材（ベゼル）７と、図１２に示すようなカバー部８とを別体で形成してもよい。 In addition, in this embodiment, an example is given of the case where the cover portion 32 is formed integrally with an exterior member (in this embodiment, the bezel main body 31) that is arranged on the visible side of the main body case 1, but the configuration of the cover portion is not limited to this.
For example, as shown in FIG. 11, an exterior member (bezel) 7 arranged on the viewing side of the main case 1 and a cover portion 8 as shown in FIG. 12 may be formed separately.

この場合にもカバー部８における連結ピンの突出部分（例えば鍔部５１１）に対応する部分には突出部分を収容する収容凹部８１を設ける。また図示は省略するが、この収容凹部８１の近傍位置でカバー部８を本体ケース１側に係止させるために、カバー部８及び本体ケース１のいずれかに係止凸部を設け、本体ケース１及びカバー部８のいずれかに係止凸部を係止させる係止凹部を形成することが好ましい。これにより、カバー部８の本体ケース１への密着性が上がり、カバー部８を外れにくくすることができる。 In this case, too, a storage recess 81 for storing the protruding portion is provided in a portion of the cover portion 8 that corresponds to the protruding portion of the connecting pin (e.g., flange portion 511). Although not shown, in order to lock the cover portion 8 to the main body case 1 at a position near this storage recess 81, it is preferable to provide a locking protrusion on either the cover portion 8 or the main body case 1, and to form a locking recess on either the main body case 1 or the cover portion 8 for locking the locking protrusion. This improves the adhesion of the cover portion 8 to the main body case 1, making it difficult for the cover portion 8 to come off.

このように外装部材（ベゼル）７とカバー部８とを別体で構成した場合には、バンド２を着脱する際にはカバー部８のみを着脱すればよく、外装部材（ベゼル）７を取り外す必要がない。これにより、外装部材（ベゼル）７のデザインの自由度等が向上する。 When the exterior member (bezel) 7 and the cover portion 8 are constructed as separate bodies in this way, only the cover portion 8 needs to be attached and detached when attaching and detaching the band 2, and there is no need to remove the exterior member (bezel) 7. This improves the freedom of design of the exterior member (bezel) 7.

また本実施形態では、本体側バンド取付け部１１のうち、ｘ方向右側（アナログ時計における３時側）に設けられた第１の本体側取付け部１２ａに第２の貫通孔１４が設けられ、連結ピン５がｘ方向右側から連結部６０に挿入される場合を例示したが、連結ピン５の挿入方向はこれに限定されない。
例えばｘ方向左側（アナログ時計における９時側）に設けられた第２の本体側取付け部１２ｂに第２の貫通孔が設けられ、連結ピン５がｘ方向左側から連結部６０に挿入される構成としてもよい。
また、右利き用、左利き用等、機種によって異なる設定のものを用意してもよい。 In addition, in this embodiment, a second through hole 14 is provided in the first body side mounting portion 12a, which is provided on the right side in the x direction (the 3 o'clock side on an analog watch) of the body side band mounting portion 11, and an example is shown in which the connecting pin 5 is inserted into the connecting portion 60 from the right side in the x direction, but the insertion direction of the connecting pin 5 is not limited to this.
For example, a second through hole may be provided in the second body side mounting portion 12b located on the left side in the x direction (the 9 o'clock side in an analog clock), and the connecting pin 5 may be inserted into the connecting portion 60 from the left side in the x direction.
Also, different settings may be provided depending on the model, such as for right-handed and left-handed users.

また例えば本実施形態では、装着機器が腕時計である時計１００である場合を例示したが、本発明のバンド取付け装置６が適用可能な装着機器は時計に限定されない。
本体ケースにバンドを取り付けて用いる機器であれば広く適用可能であり、例えば各種のスマートウォッチ、スポーツウォッチ等の電子機器、時刻の他、心拍や血流の情報等の生体情報を取得するウェアラブル機器等の装着機器に広く適用することが可能である。 In addition, for example, in the present embodiment, the case where the wearable device is a watch 100 is exemplified, but the wearable device to which the band attachment device 6 of the present invention can be applied is not limited to watches.
The device can be widely applied to any device that uses a band attached to the main case, such as various electronic devices such as smart watches and sports watches, and wearable devices that collect biometric information such as heart rate and blood flow in addition to the time.

以上本発明のいくつかの実施形態を説明したが、本発明の範囲は、上述の実施の形態に限定するものではなく、特許請求の範囲に記載された発明の範囲とその均等の範囲を含む。 Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-mentioned embodiments, but includes the scope of the invention described in the claims and its equivalents.
