　図１は関連する携帯型電子機器を正面側から見た斜視図であり、図２は図１に示される携帯型電子機器を背面側から見た斜視図である。図３は、図１および２に示されるＡ－Ａ面で携帯型電子機器を切断したときの断面図である。 FIG. 1 is a perspective view of a related portable electronic device as seen from the front side, and FIG. 2 is a perspective view of the portable electronic device shown in FIG. 1 as seen from the back side. FIG. 3 is a cross-sectional view of the portable electronic device cut along the AA plane shown in FIGS.
　図１ないし３に示すように、携帯型電子機器１は、電子機器本体２および電気部品３を備える。電子機器本体２は、正面側筐体部品４および背面側筐体部品５からなる筐体６に収納されている。 1 to 3, the portable electronic device 1 includes an electronic device body 2 and an electrical component 3. The electronic device main body 2 is housed in a housing 6 including a front housing component 4 and a back housing component 5.
　筐体６には凹み部７が形成されており、凹み部７に電気部品３が着脱自在に収納されている。図４は、凹み部７を説明するための断面図である。 A recess 7 is formed in the housing 6, and the electrical component 3 is detachably accommodated in the recess 7. FIG. 4 is a cross-sectional view for explaining the recess 7.
　図４に示されるように、背面側筐体部品５は、中空の略直方体の隣り合う２つの側面によって形成される１つの角部を除去するとともに、当該２つの側面のうちの一方にのみ隣接する一側面を除去して開放した形状を有する。背面側筐体部品５の、一側面を除去することで解放された側が正面側筐体部品４によって塞がれるように背面側筐体部品５が正面側筐体部品４に固定されている。 As shown in FIG. 4, the back-side casing component 5 removes one corner formed by two adjacent side surfaces of a hollow substantially rectangular parallelepiped and is adjacent to only one of the two side surfaces. One side surface is removed to have an open shape. The back-side housing component 5 is fixed to the front-side housing component 4 so that the side released by removing one side surface of the back-side housing component 5 is closed by the front-side housing component 4.
　凹み部７は、正面側筐体部品４の、背面側筐体部品５を向く面、および背面側筐体部品５の内側面によって区画されている。また、背面側筐体部品５の、正面側筐体部品４と対向する面の縁５ａと、背面側筐体部品５の、正面側筐体部品４に隣接する部位の縁５ｂと、背面側筐体部品５の、縁５ａ，５ｂの両端をそれぞれ結ぶ２つの縁と、によって凹み部７の開口が形成されている。 The recess 7 is defined by the surface of the front housing part 4 facing the back housing part 5 and the inner surface of the back housing part 5. Moreover, the edge 5a of the surface which opposes the front side housing component 4 of the back side housing component 5, the edge 5b of the site | part adjacent to the front side housing component 4 of the back side housing component 5, and the back side The opening of the recessed portion 7 is formed by two edges that connect both ends of the edges 5 a and 5 b of the housing component 5.
　電気部品３（図３）は、凹み部７の開口を介して凹み部７から出し入れされる。電気部品３は、凹み部７から着脱される着脱方向Ｘに移動することによって電子機器本体２から取り外される。 The electrical component 3 (FIG. 3) is taken in and out from the recess 7 through the opening of the recess 7. The electric component 3 is detached from the electronic device main body 2 by moving in the attaching / detaching direction X that is attached / detached from the recess 7.
　また、携帯型電子機器１は、凹み部７の開口を覆うカバー部材８を備える。カバー部材８は、筐体６と着脱自在に組み合わせられている。図５および６は、カバー部材８が取り外された携帯型電子機器１の斜視図および背面図である。なお、図６には、背面側筐体部品５の一部を切り欠いた背面図が示されている。 Moreover, the portable electronic device 1 includes a cover member 8 that covers the opening of the recess 7. The cover member 8 is detachably combined with the housing 6. 5 and 6 are a perspective view and a rear view of the portable electronic device 1 with the cover member 8 removed. FIG. 6 shows a rear view in which a part of the rear-side casing component 5 is cut away.
　図５および６に示すように、携帯型電子機器１は、電気部品３の着脱方向Ｘへの移動を規制するロック部材９を有する。電子機器本体２には、着脱方向Ｘと交わる方向Ｙに沿って掘られた穴１０が形成されており、ロック部材９は穴１０に突出可能に配置されている。 As shown in FIGS. 5 and 6, the portable electronic device 1 has a lock member 9 that restricts the movement of the electrical component 3 in the attaching / detaching direction X. The electronic device main body 2 is formed with a hole 10 dug along a direction Y intersecting with the attaching / detaching direction X, and the lock member 9 is disposed so as to protrude into the hole 10.
　穴１０は凹み部７よりも着脱方向Ｘ側に位置しており、ロック部材９が穴１０から突出している場合にはロック部材９は電気部品３の着脱方向Ｘへの移動を規制する。電気部品３を着脱方向Ｘへ移動させる際にはロック部材９は穴１０へ押し込まれる。 The hole 10 is located closer to the attachment / detachment direction X than the recess 7, and when the lock member 9 protrudes from the hole 10, the lock member 9 restricts the movement of the electrical component 3 in the attachment / detachment direction X. When the electric component 3 is moved in the attaching / detaching direction X, the lock member 9 is pushed into the hole 10.
　図３および６に示すように、電気部品３は外周面に接続端子（以下、部品側端子１１）を備えており、電子機器本体２は凹み部７の内部に接続端子（以下、本体側端子１２）を備えている。電気部品３が凹み部７に収納されると、部品側端子１１が本体側端子１２と接触して電気部品３は電子機器本体２と電気的に接続される。ロック部材９によって電気部品３の着脱方向Ｘへの移動が規制されることで、電気部品３はより確実に電子機器本体２と電気的に接続される。 As shown in FIGS. 3 and 6, the electrical component 3 includes a connection terminal (hereinafter, component-side terminal 11) on the outer peripheral surface, and the electronic device main body 2 has a connection terminal (hereinafter, body-side terminal) inside the recess 7. 12). When the electrical component 3 is accommodated in the recessed portion 7, the component-side terminal 11 comes into contact with the body-side terminal 12, and the electrical component 3 is electrically connected to the electronic device body 2. By restricting the movement of the electric component 3 in the attaching / detaching direction X by the lock member 9, the electric component 3 is more reliably electrically connected to the electronic device main body 2.
　また、カバー部材８は凹み部７の開口およびロック部材９を覆うように筐体６と組み合わせられているため、電気部品３やロック部材９が露出されず、携帯型電子機器１の外観が向上する。 Moreover, since the cover member 8 is combined with the housing 6 so as to cover the opening of the recess 7 and the lock member 9, the electrical component 3 and the lock member 9 are not exposed, and the appearance of the portable electronic device 1 is improved. To do.
　さらに、カバー部材８にはパッキン１３が設けられており、カバー部材８およびパッキン１３によって凹み部７への液体の流入が防止される。図７は、図３に示される携帯型電子機器１のカバー部材８付近の拡大断面図である。図８はカバー部材８を背面側から見た斜視図であり、図９はカバー部材８を正面側から見た斜視図である。図１０は、図８および図９に示されるカバー部材８を黒塗り矢印ａないしｆで示された方向から見た六面図である。図１１は、電子機器本体２の一部、電気部品３、カバー部材８、部品側端子１１および本体側端子１２の斜視図である。 Further, the cover member 8 is provided with a packing 13, and the cover member 8 and the packing 13 prevent liquid from flowing into the recess 7. FIG. 7 is an enlarged cross-sectional view of the vicinity of the cover member 8 of the portable electronic device 1 shown in FIG. FIG. 8 is a perspective view of the cover member 8 as seen from the back side, and FIG. 9 is a perspective view of the cover member 8 as seen from the front side. FIG. 10 is a six-sided view of the cover member 8 shown in FIGS. 8 and 9 as seen from the directions indicated by the black arrows a to f. FIG. 11 is a perspective view of a part of the electronic device body 2, the electrical component 3, the cover member 8, the component-side terminal 11, and the body-side terminal 12.
　図７ないし９に示すように、カバー部材８にはパッキンを保持するためのパッキン保持部１４が形成されている。パッキン保持部１４は、カバー部材８の、凹み部７の開口を覆う面のうち方向Ｙを向く面８ａから方向Ｙに向かって伸びている、断面が長方形形状を有する筒状の部材である。パッキン保持部１４の、着脱方向Ｘ側に位置する側壁は、パッキン保持部１４の、着脱方向Ｘとは反対の側に位置する側壁よりも方向Ｙに関して長く形成されている。 7 to 9, the cover member 8 is formed with a packing holding portion 14 for holding the packing. The packing holding part 14 is a cylindrical member having a rectangular cross section that extends in the direction Y from the surface 8a facing the direction Y in the surface of the cover member 8 that covers the opening of the recess 7. The side wall of the packing holding part 14 located on the attaching / detaching direction X side is formed longer in the direction Y than the side wall of the packing holding part 14 located on the side opposite to the attaching / detaching direction X.
　パッキン１３は、パッキン保持部１４の開口形状に合わせてパッキン保持部１４の外側面に配置されている。カバー部材８が筐体６に取り付けられることによってパッキン１３が筐体６の方向Ｙに沿う面に押し付けられ、カバー部材８と筐体６との間の隙間が塞がれる。したがって、携帯型電子機器１の外部から凹み部７内への液体の流入を抑制することができる。 The packing 13 is arranged on the outer surface of the packing holding part 14 in accordance with the opening shape of the packing holding part 14. By attaching the cover member 8 to the housing 6, the packing 13 is pressed against the surface along the direction Y of the housing 6, and the gap between the cover member 8 and the housing 6 is closed. Therefore, the inflow of the liquid from the outside of the portable electronic device 1 into the recessed portion 7 can be suppressed.
　なお、図１１に示される白抜き矢印は、カバー部材８がパッキン１３を押し付ける方向を示している。 Note that the white arrow shown in FIG. 11 indicates the direction in which the cover member 8 presses the packing 13.
　しかしながら、図１ないし１１に示される防水構造では、パッキン１３の一部は着脱方向Ｘとは反対のＤ１方向（図１１参照）へカバー部材８によって押し付けられている。そのため、例えば落下時の衝撃といった、携帯型電子機器１に比較的大きな衝撃が加えられた場合、防水性能が低下する虞があった。 However, in the waterproof structure shown in FIGS. 1 to 11, a part of the packing 13 is pressed by the cover member 8 in the direction D1 (see FIG. 11) opposite to the attaching / detaching direction X. For this reason, when a relatively large impact is applied to the portable electronic device 1 such as an impact at the time of dropping, the waterproof performance may be deteriorated.
　具体的には、電気部品３は、携帯型電子機器１の落下衝撃により着脱方向Ｘへ向かって移動しようとする。落下の衝撃が比較的大きい場合には、電気部品３は一時的にロック部材９を着脱方向Ｘへ押し曲げてカバー部材８に着脱方向Ｘの衝撃を加える。その結果、パッキン１３の一部に加えられていたＤ１方向の力が一時的に弱まり、カバー部材８と筐体６との間に隙間が形成されて防水性能が低下してしまう。 Specifically, the electrical component 3 tends to move in the attaching / detaching direction X due to a drop impact of the portable electronic device 1. When the impact of dropping is relatively large, the electrical component 3 temporarily pushes and bends the lock member 9 in the attaching / detaching direction X and applies the impact in the attaching / detaching direction X to the cover member 8. As a result, the force in the direction D1 applied to a part of the packing 13 is temporarily weakened, and a gap is formed between the cover member 8 and the housing 6 to deteriorate the waterproof performance.
　このような問題点を解決する防水構造を備えた携帯型電子機器が特開２００３－１４２８４１号公報（以下、「特許文献１」と称す）に開示されている。図１２を用いて特許文献１に開示されている携帯型電子機器について説明する。なお、図１ないし１１に示される構成要素と同一の構成要素には同一の符号を付し、その説明は省略する。 A portable electronic device having a waterproof structure that solves such problems is disclosed in Japanese Patent Laid-Open No. 2003-142841 (hereinafter referred to as “Patent Document 1”). A portable electronic device disclosed in Patent Document 1 will be described with reference to FIG. The same components as those shown in FIGS. 1 to 11 are denoted by the same reference numerals, and the description thereof is omitted.
　図１２は、特許文献１に開示されている携帯型電子機器の一部を示す斜視図である。図１２に示すように、特許文献１に開示されている携帯型電子機器１５のカバー部材８は、凹み部７の開口を覆う側に、筐体６の凹み部７に挿入可能に形成されたパッキン受け１６を備える。カバー部材８はヒンジピン１７を介して回転自在に筐体６に連結されており、ヒンジピン１７を中心にカバー部材８が回転することによって凹み部７にパッキン受け１６が挿抜される。 FIG. 12 is a perspective view showing a part of the portable electronic device disclosed in Patent Document 1. FIG. As shown in FIG. 12, the cover member 8 of the portable electronic device 15 disclosed in Patent Document 1 is formed on the side covering the opening of the recess 7 so as to be insertable into the recess 7 of the housing 6. A packing receiver 16 is provided. The cover member 8 is rotatably connected to the housing 6 via a hinge pin 17, and the packing receiver 16 is inserted into and removed from the recessed portion 7 as the cover member 8 rotates around the hinge pin 17.
　特許文献１の防水構造では、パッキン１３は、パッキン受け１６の外周面のうち、パッキン受け１６が凹み部７に挿入された際に凹み部７の内側面と対向する領域に配置されている。すなわち、パッキン受け１６が凹み部７に挿入された状態では、パッキン１３は着脱方向Ｘと交わる方向に押し付けられておりパッキン受け１６に着脱方向Ｘの衝撃が加えられてもパッキン受け１６がパッキン１３を押し付ける力は変化しない。したがって、携帯型電子機器１５に比較的大きな衝撃が加えられても、携帯型電子機器１５の防水性能は低下しない。 In the waterproof structure of Patent Document 1, the packing 13 is disposed in a region of the outer peripheral surface of the packing receiver 16 that faces the inner surface of the recess 7 when the packing receiver 16 is inserted into the recess 7. That is, in a state where the packing receiver 16 is inserted into the recess 7, the packing 13 is pressed in a direction crossing the attaching / detaching direction X, and the packing receiver 16 is not affected by an impact in the attaching / detaching direction X. The force of pressing does not change. Therefore, even if a relatively large impact is applied to the portable electronic device 15, the waterproof performance of the portable electronic device 15 does not deteriorate.
特開２００３－１４２８４１号公報JP 2003-142841 A
　しかしながら、特許文献１に開示されている防水構造では、図１２に示すように、パッキン受け１６を有するカバー部材８がヒンジピン１７を介して筐体６に連結されている。そのため、カバー部材８におけるパッキン受け１６の位置や、筐体６へのカバー部材８の連結位置によっては、凹み部７内におけるパッキン受け１６の位置が偏る。その結果、パッキン１３に加えられる力が偏り、防水性能が低下してしまう。 However, in the waterproof structure disclosed in Patent Document 1, the cover member 8 having the packing receiver 16 is connected to the housing 6 via the hinge pin 17 as shown in FIG. Therefore, depending on the position of the packing receiver 16 in the cover member 8 and the connecting position of the cover member 8 to the housing 6, the position of the packing receiver 16 in the recessed portion 7 is biased. As a result, the force applied to the packing 13 is biased and the waterproof performance is reduced.
　また、特許文献１に開示されている防水構造では、凹み部７に挿入されるパッキン受け１６がカバー部材８に直接固定されている。そして、カバー部材８の回転がロック部材１８を用いて規制されることでパッキン受け１６の着脱方向Ｘへの移動が規制される。ロック部材１８をカバー部材８で覆うことができないため、ロック部材１８が露出せざるを得ない。その結果、携帯型電子機器１５の外観が煩雑に見える。 In the waterproof structure disclosed in Patent Document 1, the packing receiver 16 inserted into the recess 7 is directly fixed to the cover member 8. Then, the movement of the packing receiver 16 in the attaching / detaching direction X is restricted by restricting the rotation of the cover member 8 using the lock member 18. Since the lock member 18 cannot be covered with the cover member 8, the lock member 18 must be exposed. As a result, the appearance of the portable electronic device 15 looks complicated.
　そこで、本発明の目的の一例は、外観品位が低下することなくより確実に防水することが可能な防水構造、および防水方法を提供することにある。 Therefore, an example of the object of the present invention is to provide a waterproof structure and a waterproof method capable of waterproofing more reliably without deteriorating the appearance quality.
　上記目的を達成するために、本発明の一つの態様は、筐体と、閉塞部材と、パッキンと、ロック部材と、カバー部材と、を備える。筐体は凹み部を有する。閉塞部材は凹み部に着脱自在に配置され、凹み部の開口を塞いでいる。パッキンは、閉塞部材の、閉塞部材の凹み部への着脱方向と交わる方向を向く側面と、前記凹み部の、該側面に対向する内側面との間の隙間を塞いでいる。ロック部材は、筐体に設けられ、閉塞部材の着脱方向への移動を規制する。カバー部材は、着脱自在に筐体と組み合わせられ、凹み部に配置された閉塞部材、および該閉塞部材の着脱方向への移動を規制した状態のロック部材を覆っている。 In order to achieve the above object, one aspect of the present invention includes a housing, a closing member, a packing, a lock member, and a cover member. The housing has a recess. The closing member is detachably disposed in the recessed portion and closes the opening of the recessed portion. The packing blocks a gap between a side surface of the closing member facing in a direction intersecting with the attaching / detaching direction of the closing member to the recessed portion and an inner surface of the recessed portion facing the side surface. The lock member is provided in the housing and restricts movement of the closing member in the attaching / detaching direction. The cover member is detachably combined with the housing, and covers the closing member disposed in the recess and the lock member in a state where movement of the closing member in the attaching / detaching direction is restricted.
　また、本発明の一つの態様は、筐体に形成された凹み部の防水方法に係る。防水方法は用意ステップと配置ステップと閉塞ステップと規制ステップと被覆ステップとを含む。用意ステップは、凹み部に着脱自在に形成された閉塞部材と、パッキンと、閉塞部材の移動を規制するロック部材と、筐体に着脱自在に形成されたカバー部材と、を用意するステップである。配置ステップは、閉塞部材の凹み部への着脱方向と交わる方向に向いた閉塞部材の側面と、閉塞部材が凹み部に配置された際に該側面に対向する凹み部の内側面と、の間の隙間を塞ぐ位置にパッキンを配置するステップである。閉塞ステップは、閉塞部材を凹み部に挿入して閉塞部材およびパッキンで凹み部の開口を閉塞するステップである。規制ステップは、ロック部材を用いて着脱方向への閉塞部材の移動を規制するステップである。被覆ステップは、カバー部材を筐体に取り付けて、凹み部に配置された閉塞部材、および閉塞部材の着脱方向への移動を規制した状態のロック部材を覆うステップである。 Also, one aspect of the present invention relates to a method for waterproofing a recess formed in a housing. The waterproofing method includes a preparation step, an arrangement step, a closing step, a regulating step, and a covering step. The preparing step is a step of preparing a closing member that is detachably formed in the recess, a packing, a lock member that restricts movement of the closing member, and a cover member that is detachably formed on the housing. . The disposing step is between the side surface of the closing member facing in the direction intersecting with the attaching / detaching direction to the recessed portion of the closing member and the inner surface of the recessed portion facing the side surface when the closing member is disposed in the recessed portion. This is a step of arranging the packing at a position for closing the gap. The closing step is a step of inserting the closing member into the recess and closing the opening of the recess with the closing member and the packing. The restricting step is a step of restricting the movement of the closing member in the attaching / detaching direction using the lock member. The covering step is a step of attaching the cover member to the housing and covering the closing member disposed in the recess and the locking member in a state where movement of the closing member in the attaching / detaching direction is restricted.
　本発明によれば、外観品位が低下することなくより確実に防水することができる。 According to the present invention, waterproofing can be performed more reliably without deteriorating the appearance quality.

FIG. 15 is a cross-sectional view of the portable electronic device cut along the BB plane shown in FIGS.
　図１３ないし１５に示すように、本実施形態例に係る携帯型電子機器１９は、電子機器本体２、電気部品３、筐体６およびカバー部材８を備える。電気部品３としては、電池が挙げられる。 As shown in FIGS. 13 to 15, a portable electronic device 19 according to this embodiment includes an electronic device body 2, an electrical component 3, a housing 6, and a cover member 8. As the electrical component 3, a battery is used.
　筐体６は正面側筐体部品４および背面側筐体部品５からなり、正面側筐体部品４および背面側筐体部品５が組み合わせられることによって電気部品３を収納するための凹み部７が形成されている。図１６は、凹み部７を説明するための断面図である。 The housing 6 includes a front-side housing component 4 and a back-side housing component 5, and a recess 7 for housing the electrical component 3 is obtained by combining the front-side housing component 4 and the back-side housing component 5. Is formed. FIG. 16 is a cross-sectional view for explaining the recess 7.
　図１６に示されるように、背面側筐体部品５は、中空の略直方体の隣り合う２つの側面によって形成される１つの角部を除去するとともに、当該２つの側面のうちの一方にのみ隣接する一側面を除去して開放した形状を有する。背面側筐体部品５の、一側面を除去して解放されている側を塞ぐように背面側筐体部品５が正面側筐体部品４に固定されている。 As shown in FIG. 16, the back-side housing component 5 removes one corner formed by two adjacent side surfaces of a hollow substantially rectangular parallelepiped and is adjacent to only one of the two side surfaces.

　電気部品３（図１５）は、背面側筐体部品５の、正面側筐体部品４によって塞がれていない開口を介して凹み部７に出し入れされる。電気部品３は凹み部７から着脱される着脱方向Ｘに移動することによって電子機器本体２から取り外される。 The electrical component 3 (FIG. 15) is taken in and out of the recessed portion 7 through the opening of the rear side casing component 5 that is not blocked by the front casing component 4. The electric component 3 is detached from the electronic device main body 2 by moving in the attaching / detaching direction X to be attached / detached from the recess 7.
　正面側筐体部品４には、ディスプレイ部２０が配置されている。ディスプレイ部２０は、携帯型電子機器１９に予め記憶された画像や、携帯型電子機器１９の外部から携帯型電子機器１９へ取り込まれた画像などを表示する。 The display unit 20 is disposed on the front casing part 4. The display unit 20 displays an image stored in advance in the portable electronic device 19 or an image taken into the portable electronic device 19 from the outside of the portable electronic device 19.
　カバー部材８は着脱自在に筐体６と組み合わせられている。図１７および図１８は、カバー部材８が取り外された携帯型電子機器１９の斜視図および背面図である。なお、図１８では、背面側筐体部品５の一部を切り欠いた背面図が示されている。図１９は、携帯型電子機器１９の、カバー部材８が組み合わせられる部分の拡大図である。図２０は、図１９に示される部分を着脱方向Ｘに並行かつ正面側筐体部品４および背面側筐体部品５を横切る面で切断した状態の断面図である。 The cover member 8 is detachably combined with the housing 6. 17 and 18 are a perspective view and a rear view of the portable electronic device 19 with the cover member 8 removed. In addition, in FIG. 18, the rear view which notched some back side housing components 5 is shown. FIG. 19 is an enlarged view of a portion of the portable electronic device 19 where the cover member 8 is combined. FIG. 20 is a cross-sectional view of the state shown in FIG. 19 taken along a plane parallel to the attachment / detachment direction X and across the front-side casing component 4 and the back-side casing component 5.
　図１７ないし２０に示すように、携帯型電子機器１９は電気部品３の着脱方向Ｘへの移動を規制するロック部材９を有する。ロック部材９は、正面側筐体部品４および背面側筐体部品５の、凹み部７の開口よりも着脱方向Ｘ側に形成された穴１０であって、着脱方向Ｘと交わる方向Ｙに深さを有する穴１０に突出可能に配置されている。 17 to 20, the portable electronic device 19 has a lock member 9 that restricts movement of the electrical component 3 in the attaching / detaching direction X. The lock member 9 is a hole 10 formed in the attachment / detachment direction X side of the opening of the recessed portion 7 in the front-side housing component 4 and the back-side housing component 5 and deep in the direction Y intersecting the attachment / detachment direction X. It is arrange | positioned so that it can protrude in the hole 10 which has thickness.
　穴１０は略直方体形状を有しており、略直方体形状の長手方向は着脱方向Ｘおよび方向Ｙと交わる方向を向いている。穴１０の、着脱方向Ｘに対向する２つの側面には方向Ｘに沿って突出する突起１０ａがそれぞれ形成されている。２つの突起１０ａはその突出方向の延長線上に位置している。 The hole 10 has a substantially rectangular parallelepiped shape, and the longitudinal direction of the substantially rectangular parallelepiped shape faces the direction intersecting with the attaching / detaching direction X and the direction Y. On the two side surfaces of the hole 10 facing the attaching / detaching direction X, protrusions 10a protruding along the direction X are formed. The two protrusions 10a are located on an extension line in the protruding direction.
　ロック部材９は穴１０の形状に対応した略直方体形状を有する。ロック部材９の、突起１０ａに対応する位置には凹み９ａが形成されている。突起１０ａは凹み９ａに嵌っており、ロック部材９は穴１０から脱落しない。 The lock member 9 has a substantially rectangular parallelepiped shape corresponding to the shape of the hole 10. A recess 9a is formed at a position of the lock member 9 corresponding to the protrusion 10a. The protrusion 10 a is fitted in the recess 9 a, and the lock member 9 does not fall out of the hole 10.
　また、２つの突起１０ａがその突出方向の延長線上に位置しているため、ロック部材９は２つの突起１０ａを結ぶ軸を中心に回転することができる。ロック部材９が当該軸を中心に回転することによって、ロック部材９が穴１０から突出する状態と、ロック部材９が穴１０に押し込まれる状態と、が切り替えられる。 Further, since the two protrusions 10a are located on the extension line in the protruding direction, the lock member 9 can rotate around the axis connecting the two protrusions 10a. When the lock member 9 rotates about the axis, the state in which the lock member 9 protrudes from the hole 10 and the state in which the lock member 9 is pushed into the hole 10 are switched.
　ロック部材９が穴１０から突出している場合には、ロック部材９は、凹み７から着脱方向Ｘへ向かったところに位置し、電気部品３の着脱方向Ｘへの移動を規制する。ロック部材９が穴１０へ押し込まれると、ロック部材９は凹み７から着脱方向Ｘへ向かったところに位置しなくなり、電気部品３を着脱方向Ｘへ移動させることが可能になる。図２１および２２は、ロック部材９が穴１０に押し込まれた状態の携帯型電子機器１９の斜視図および断面図である。 When the lock member 9 protrudes from the hole 10, the lock member 9 is located in the direction from the recess 7 in the attaching / detaching direction X, and restricts the movement of the electric component 3 in the attaching / detaching direction X. When the lock member 9 is pushed into the hole 10, the lock member 9 is no longer positioned in the attachment / detachment direction X from the recess 7, and the electric component 3 can be moved in the attachment / detachment direction X. 21 and 22 are a perspective view and a cross-sectional view of the portable electronic device 19 in a state in which the lock member 9 is pushed into the hole 10.
　図１５および１７に示すように、電気部品３は外周面に部品側端子１１を備えており、電子機器本体２は凹み部７の内部に本体側端子１２を備えている。電気部品３が凹み部７に収納されると部品側端子１１が本体側端子１２と接触し、電気部品３は電子機器本体２と電気的に接続される。 As shown in FIGS. 15 and 17, the electrical component 3 includes a component-side terminal 11 on the outer peripheral surface, and the electronic device main body 2 includes a body-side terminal 12 inside the recessed portion 7. When the electrical component 3 is housed in the recess 7, the component-side terminal 11 comes into contact with the body-side terminal 12, and the electrical component 3 is electrically connected to the electronic device body 2.
　さらに、図１５ないし図１８に示すように、携帯型電子機器１９は凹み部７の開口を塞ぐ閉塞部材２１を備える。閉塞部材２１は、凹み部７に着脱自在に形成され、凹み部７の、電気部品３とロック部材９との間に配置されている。ロック部材９が穴１０から突出している状態においては、閉塞部材２１の着脱方向Ｘへの移動はロック部材９によって規制される。 Furthermore, as shown in FIGS. 15 to 18, the portable electronic device 19 includes a closing member 21 that closes the opening of the recess 7. The closing member 21 is detachably formed in the recess 7 and is disposed between the electrical component 3 and the lock member 9 in the recess 7. When the lock member 9 protrudes from the hole 10, the movement of the closing member 21 in the attaching / detaching direction X is restricted by the lock member 9.
　ロック部材９による閉塞部材２１の着脱方向Ｘへの移動が規制されていない状態では、携帯型電子機器１９のユーザは電気部品３および閉塞部材２１を筐体６から取り外すことができる。図２３および図２４は、凹み部７から電気部品３および閉塞部材２１が引き出された状態の携帯型電子機器１９の斜視図及び断面図である。 In a state where movement of the closing member 21 in the attaching / detaching direction X by the lock member 9 is not restricted, the user of the portable electronic device 19 can remove the electrical component 3 and the closing member 21 from the housing 6. 23 and 24 are a perspective view and a cross-sectional view of the portable electronic device 19 in a state where the electrical component 3 and the closing member 21 are pulled out from the recess 7.
　閉塞部材２１の構造について、図２２ないし図２６を用いて説明する。図２５は閉塞部材２１の六面図であり、図２６は携帯型電子機器１９の電気部品３、部品側端子１１、本体側端子１２および閉塞部材２１の斜視図である。 The structure of the closing member 21 will be described with reference to FIGS. FIG. 25 is a six-sided view of the closing member 21, and FIG. 26 is a perspective view of the electrical component 3, the component-side terminal 11, the body-side terminal 12, and the closing member 21 of the portable electronic device 19.
　図２２ないし図２６に示すように、パッキン１３は、閉塞部材２１の外側面のうちの、着脱方向Ｘと交わる方向を向く側面に配置されている。すなわち、閉塞部材２１が凹み部７内に配置された状態では、パッキン１３は着脱方向Ｘと交わる方向（図２６の白抜き矢印方向）に押し付けられ、凹み部７の内側面と閉塞部材２１との間の隙間を塞ぐ。 As shown in FIGS. 22 to 26, the packing 13 is disposed on the side surface of the outer surface of the closing member 21 that faces the direction intersecting with the attaching / detaching direction X. That is, in a state where the closing member 21 is disposed in the recessed portion 7, the packing 13 is pressed in a direction intersecting with the attaching / detaching direction X (the direction of the white arrow in FIG. 26), and the inner surface of the recessed portion 7 and the closing member 21 are Block the gap between.
　電気部品３は、凹み部７と閉塞部材２１とで形成された空間内に収納されており、当該空間内で電子機器本体２と電気的に接続されている。したがって、電気部品３と電子機器本体２との間の電気接続部に液体が付着することがなく、携帯型電子機器１９の故障を抑制することができる。 The electrical component 3 is accommodated in a space formed by the recessed portion 7 and the closing member 21 and is electrically connected to the electronic device main body 2 in the space. Therefore, no liquid adheres to the electrical connection portion between the electrical component 3 and the electronic device main body 2, and the failure of the portable electronic device 19 can be suppressed.
　パッキン１３が着脱方向Ｘと交わる方向に押し付けられているため、閉塞部材２１に着脱方向Ｘの衝撃が加えられても、閉塞部材２１がパッキン１３を押し付ける力は変化しない。 Since the packing 13 is pressed in the direction crossing the attaching / detaching direction X, even if an impact in the attaching / detaching direction X is applied to the closing member 21, the force with which the closing member 21 presses the packing 13 does not change.
　仮に、電気部品３および閉塞部材２１に加えられる衝撃がロック部材９を一時的に押し曲げる程度に大きい場合であっても、閉塞部材２１が凹み部７から抜けない限りパッキン１３は凹み部７の内側面とパッキン抜け１９との間の隙間を塞ぎ続ける。そのため、携帯型電子機器１９の防水性能は維持される。 Even if the impact applied to the electrical component 3 and the closing member 21 is large enough to temporarily push and bend the lock member 9, the packing 13 is not in the recessed portion 7 as long as the closing member 21 does not come out of the recessed portion 7. The gap between the inner surface and the packing removal 19 is continuously closed. Therefore, the waterproof performance of the portable electronic device 19 is maintained.
　また、閉塞部材２１は、凹み部７内に着脱自在に形成されている。すなわち、閉塞部材２１は、筐体６およびカバー部材８から独立しているため、凹み部７内における閉塞部材２１の位置は偏らない。したがって、閉塞部材２１はパッキン１３を均等に凹み部７の内側面に押し付け、防水性能の低下が抑制される。 Further, the closing member 21 is detachably formed in the recessed portion 7. That is, since the closing member 21 is independent from the housing 6 and the cover member 8, the position of the closing member 21 in the recessed portion 7 is not biased. Therefore, the closing member 21 presses the packing 13 evenly against the inner surface of the recessed portion 7, and the deterioration of the waterproof performance is suppressed.
　さらに、カバー部材８は筐体６に着脱自在に形成されている。したがって、ロック部材９は、カバー部材８の筐体６への着脱を規制することなく閉塞部材２１の着脱方向Ｘへの移動を規制することができる。その結果、カバー部材８は、凹み部７内に配置された閉塞部材２１、および閉塞部材２１の着脱方向Ｘへの移動を規制した状態のロック部材９を覆うことができ、携帯型電子機器１９の外観品位が向上する。 Further, the cover member 8 is detachably formed on the housing 6. Therefore, the lock member 9 can restrict the movement of the closing member 21 in the attachment / detachment direction X without restricting the attachment / detachment of the cover member 8 to / from the housing 6. As a result, the cover member 8 can cover the closing member 21 disposed in the recess 7 and the lock member 9 in a state where the movement of the closing member 21 in the attaching / detaching direction X is restricted, and the portable electronic device 19. The appearance quality of is improved.
　閉塞部材２１は、凹み部７から突出した突出部２２を含んでいてもよい。携帯型電子機器１９のユーザは、突出部２２をつまむことによって閉塞部材２１を凹み部７から容易に引き出すことができる。 The closing member 21 may include a protruding portion 22 protruding from the recessed portion 7. A user of the portable electronic device 19 can easily pull out the closing member 21 from the recess 7 by pinching the protrusion 22.
　また、パッキン１３は、閉塞部材２１の外側面でなく、凹み部７の内側面に配置されていてもよい。すなわち、パッキン１３は、閉塞部材２１の、着脱方向Ｘと交わる方向に向いた側面と、当該側面に対向する凹み部７の内側面との間の隙間に配され、当該隙間を塞いでいればよい。 Further, the packing 13 may be disposed not on the outer surface of the closing member 21 but on the inner surface of the recessed portion 7. That is, the packing 13 is disposed in a gap between the side surface of the closing member 21 facing in the direction intersecting with the attaching / detaching direction X and the inner side surface of the recessed portion 7 facing the side surface, and closes the gap. Good.
　続いて、筐体６に形成された凹み部７の防水方法について図１３ないし図２６を用いて説明する。 Subsequently, a waterproofing method for the recess 7 formed in the housing 6 will be described with reference to FIGS.
　防水方法は、用意ステップを含む。用意ステップは、凹み部７内に着脱自在に形成された閉塞部材２１と、パッキン１３と、閉塞部材２１の移動を規制するロック部材９と、筐体６に着脱自在に形成されたカバー部材８と、を用意するステップである。 Waterproofing method includes a preparation step. The preparation step includes a closing member 21 detachably formed in the recess 7, a packing 13, a lock member 9 for restricting movement of the closing member 21, and a cover member 8 formed detachably on the housing 6. And a step of preparing
　各種部材が用意されたところで、着脱方向Ｘと交わる方向を向く閉塞部材２１の側面と、閉塞部材２１が凹み部７内に配置された際に該側面に対向する凹み部７の内側面と、の間の隙間を塞ぐ位置にパッキン１３が配置される（配置ステップ）。 When various members are prepared, the side surface of the closing member 21 facing the direction intersecting the attaching / detaching direction X, the inner surface of the recessed portion 7 that faces the side surface when the closing member 21 is disposed in the recessed portion 7, The packing 13 is disposed at a position that closes the gap between them (arrangement step).
　パッキン１３が前記位置に配置され後、閉塞部材２１が凹み部７内に挿入されて閉塞部材２１およびパッキン１３で凹み部７の開口が閉塞され（閉塞ステップ）、ロック部材９を用いて閉塞部材２１の着脱方向Ｘへの移動が規制される（規制ステップ）。その後、カバー部材８が筐体６に取り付けられることで、カバー部材８は凹み部７内に配置された閉塞部材２１、および閉塞部材２１の着脱方向Ｘへの移動を規制した状態のロック部材９を被覆する（被覆ステップ）。 After the packing 13 is disposed at the above position, the closing member 21 is inserted into the recessed portion 7, and the opening of the recessed portion 7 is closed by the closing member 21 and the packing 13 (closing step). 21 is restricted from moving in the attachment / detachment direction X (regulation step). Thereafter, the cover member 8 is attached to the housing 6, so that the cover member 8 is disposed in the recess 7, and the lock member 9 is in a state in which movement of the closure member 21 in the attaching / detaching direction X is restricted. Is coated (coating step).
　電子機器本体２および電気部品３は、閉塞部材２１を用いて凹み部７の開口を閉塞する前に筐体６および凹み部７にそれぞれ収納されていればよい。 The electronic device main body 2 and the electrical component 3 may be accommodated in the housing 6 and the recessed portion 7 before closing the opening of the recessed portion 7 using the closing member 21, respectively.

That is, in a state in which the electrical component 3 is inserted into the recessed portion 7, the packing 13 is pressed in a direction intersecting with the attaching / detaching direction X and closes the gap between the inner surface of the recessed portion 7 and the outer peripheral surface of the electrical component 3.
　パッキン１３の各部位が着脱方向Ｘと交わる方向に押し付けられているため、電気部品３に着脱方向Ｘの衝撃が加えられても、電気部品３がパッキン１３を押し付ける力は変化しない。 Since each part of the packing 13 is pressed in a direction crossing the attaching / detaching direction X, even if an impact in the attaching / detaching direction X is applied to the electrical component 3, the force with which the electrical component 3 presses the packing 13 does not change.
　仮に、電気部品３に加えられる衝撃がロック部材９を一時的に押し曲げる程度に大きい場合であっても、電気部品３の、パッキン１３が配された部分が凹み部７から抜けない限りパッキン１３は凹み部７の内側面と電気部品３の外周面との間の隙間を塞ぎ続ける。そのため、携帯型電子機器２３の防水性能は維持される。 Even if the impact applied to the electrical component 3 is large enough to temporarily push and bend the lock member 9, the packing 13 as long as the portion of the electrical component 3 where the packing 13 is disposed does not come out of the recess 7. Keeps closing the gap between the inner surface of the recess 7 and the outer peripheral surface of the electrical component 3. Therefore, the waterproof performance of the portable electronic device 23 is maintained.
　また、電気部品３は凹み部７内に着脱自在に形成されている。すなわち、電気部品３は筐体６およびカバー部材８から独立しているため、凹み部７内における電気部品３の位置は偏らない。したがって、電気部品３はパッキン１３を均等に凹み部７の内側面に押し付け、防水性能の低下が抑制される。 The electrical component 3 is detachably formed in the recess 7. That is, since the electrical component 3 is independent of the housing 6 and the cover member 8, the position of the electrical component 3 in the recess 7 is not biased. Therefore, the electrical component 3 presses the packing 13 evenly against the inner surface of the recessed portion 7, and a decrease in waterproof performance is suppressed.
　さらに、本実施形態例では、第１の実施形態例に係る携帯型電子機器１９が備える閉塞部材２１に相当する部材を必要としないため、部品点数の削減を図ることができるとともに、電気部品３の大型化を図ることが可能になる。 Further, in the present embodiment example, since a member corresponding to the closing member 21 provided in the portable electronic device 19 according to the first embodiment example is not required, the number of components can be reduced and the electrical component 3 can be reduced. Can be made larger.
　電気部品３は、着脱方向Ｘを向く面に凹み部７から突出する突出部２４を含んでいてもよい。携帯型電子機器１９のユーザは突出部２４をつまむことによって電気部品３を凹み部７から容易に引き出すことができる。 The electrical component 3 may include a protruding portion 24 protruding from the recessed portion 7 on the surface facing the attaching / detaching direction X. A user of the portable electronic device 19 can easily pull out the electrical component 3 from the recess 7 by pinching the protrusion 24.
　また、パッキン１３は、電気部品３の外側面でなく、凹み部７の内側面に配置されていてもよい。すなわち、パッキン１３は、電気部品３の、着脱方向Ｘと交わる方向を向く側面と、当該側面に対向する凹み部７の内側面との間の隙間に配され、当該隙間を塞いでいればよい。 Further, the packing 13 may be disposed not on the outer surface of the electrical component 3 but on the inner surface of the recess 7. That is, the packing 13 is disposed in a gap between the side surface of the electrical component 3 facing in the direction intersecting with the attaching / detaching direction X and the inner side surface of the recessed portion 7 facing the side surface, and the packing 13 may be closed. .
