Description

電子機器、電池パック、及び粘着シートElectronic device, battery pack, and adhesive sheet
　本発明は、薄型電池を電源として内蔵する電子機器と、この電子機器に内蔵される電池パック及び粘着シートに関する。 The present invention relates to an electronic device incorporating a thin battery as a power source, and a battery pack and an adhesive sheet incorporated in the electronic device.
　携帯型の電子機器は、電源として内蔵する薄型電池からなる電池パックによって外装ケースを薄くできる。携帯型の電子機器は、携帯電話、スマートフォン、タブレット、電子ブック、ノート型パソコン、ゲーム機や音楽プレーヤーなどがある。さらに近年の電子機器は、電池パックをユーザーが脱着して交換できない構造として、外装ケースをさらに薄くする傾向にある。この電子機器は、外装ケース内の収納スペースに両面接着テープを介して電池パックを固定している。両面接着テープは、電池パック背面と収納スペース底面との間に配置されて、電池パックを収納スペースに固定する。（特許文献１、２参照） In portable electronic devices, the outer case can be made thin by a battery pack made of a thin battery built in as a power source. Examples of portable electronic devices include mobile phones, smartphones, tablets, electronic books, notebook computers, game machines and music players. Furthermore, recent electronic devices tend to have a thinner outer case as a structure in which the user cannot remove and replace the battery pack. In this electronic device, a battery pack is fixed to a storage space in an exterior case via a double-sided adhesive tape. The double-sided adhesive tape is disposed between the back surface of the battery pack and the bottom surface of the storage space, and fixes the battery pack to the storage space.

This electronic device has the feature that the battery pack can be fixed extremely firmly in the storage space. However, when repairing or disposing of the electronic device, even the service factory or the manufacturer cannot easily take out the battery pack. . The battery pack is removed from the storage space by inserting a flathead screwdriver or the like into the gap between the outer periphery and the storage space. Since the bottom surface of the battery pack is bonded to the bottom surface of the storage space with a double-sided adhesive tape, the double-sided adhesive tape cannot be peeled unless the thin battery is damaged or pulled up so hard that it bends.

　以上の電子機器と電池パックは、薄型電池を安定して確実に収納スペースに固定しながら、取り出すときにはこれを損傷することなく、簡単に電子機器から速やかに取り外しできる特徴がある。損傷することなく簡単に取り外しできるのは、薄型電池の露出面に接着している剥離シート部を剥離して、摘みシート部のツマミ部を引っ張って、収納スペースから取り出しできるからである。とくに、剥離シート部を剥離する状態で、薄型電池の背面に接着している摘みシート部のツマミ部を引っ張って収納スペースから取り出されるので、薄型電池は背面から持ち上げられて、すなわち、収納スペースから最も確実に取り出される方向に引き上げられて取り出しされるので、簡単かつ確実に、しかも速やかに損傷することなく取り出される。さらに、薄型電池は表面の露出面に接着される剥離シート部を介して収納スペースに固定される。 The above electronic devices and battery packs have the feature that a thin battery can be easily and quickly removed from an electronic device without damaging the thin battery while it is securely fixed in a storage space. The reason why the sheet can be easily removed without being damaged is that it can be taken out of the storage space by peeling the release sheet part adhered to the exposed surface of the thin battery and pulling the knob part of the knob sheet part. In particular, in the state where the release sheet portion is peeled off, the knob portion of the knob sheet portion adhered to the back surface of the thin battery is pulled out of the storage space, so that the thin battery is lifted from the back surface, that is, from the storage space. Since it is pulled up and taken out in the direction of taking out most reliably, it is taken out easily, reliably and quickly without being damaged. Further, the thin battery is fixed to the storage space via a release sheet portion bonded to the exposed surface.
　薄型電池の露出面に接着される剥離シート部は、取り出し時に剥離できる程度の接着で露出面に接着しながら、薄型電池を安定して確実に収納スペースに固定できる特徴がある。それは、図１３に示すように、振動などで薄型電池が収納スペースから外れようとする外れ力（Ｆ）が作用する状態で、剥離シート部には接着面と平行な擦れ力（Ｆ１）が作用するからである。剥離シート部は、接着面に直交する方向に剥離力が作用して、露出面から簡単に剥離されても、接着面と平行な擦れ力（Ｆ１）に対して簡単には剥離されない。したがって、剥離シート部を剥離できる程度の接着力で露出面に接着しながら、収納スペースに確実に固定できる特徴がある。ちなみに、薄型電池が両面接着テープを介して収納スペースの底面に固定される従来の固定構造は、外れ力（Ｆ）が両面接着テープを剥離する方向に作用する。両面接着テープは、接着面と直交する剥離方向に作用する力では剥離しやすい。このため、従来の固定構造は、振動などで薄型電池が収納スペースから外れないように、極めて強固な接着力の両面接着テープで薄型電池を収納スペースに固定している。このため、薄型電池を収納スペースから簡単に取り外すときには、簡単に取り出しできない欠点があった。 The release sheet portion that is bonded to the exposed surface of the thin battery is characterized in that the thin battery can be stably and securely fixed to the storage space while being bonded to the exposed surface with an adhesive that can be peeled off when taken out. As shown in FIG. 13, the peeling sheet portion is subjected to a rubbing force (F1) parallel to the adhesive surface in a state in which a detaching force (F) is applied to the thin battery due to vibration or the like. Because it does. Even if the release sheet portion is peeled easily from the exposed surface due to a peeling force acting in a direction perpendicular to the bonding surface, the peeling sheet portion is not easily peeled against the rubbing force (F1) parallel to the bonding surface. Therefore, there is a feature that it can be securely fixed in the storage space while adhering to the exposed surface with an adhesive force that can peel the release sheet portion. Incidentally, in the conventional fixing structure in which the thin battery is fixed to the bottom surface of the storage space via the double-sided adhesive tape, the detachment force (F) acts in the direction of peeling the double-sided adhesive tape. The double-sided adhesive tape is easily peeled off by a force acting in the peeling direction perpendicular to the adhesive surface. For this reason, in the conventional fixing structure, the thin battery is fixed to the storage space with a double-sided adhesive tape having an extremely strong adhesive force so that the thin battery is not detached from the storage space due to vibration or the like. For this reason, when the thin battery is easily removed from the storage space, there is a drawback that it cannot be easily removed.

　図１と図２に示す携帯型の電子機器１は、外装ケース２内に設けた収納スペース３に取り出し自在に電池パック４を配置している。電池パック４は、収納スペース３に配置される薄型電池５を有し、この薄型電池５を収納スペース３に取り出しできるように粘着シート６で固定している。 1 and FIG. 2, a battery pack 4 is disposed in a storage space 3 provided in an exterior case 2 so as to be freely taken out. The battery pack 4 has a thin battery 5 disposed in the storage space 3 and is fixed with an adhesive sheet 6 so that the thin battery 5 can be taken out into the storage space 3.
　図１と図２の携帯型の電子機器１は、外装ケース２の内部に、電池パック４を収納するための凹部を設けて、凹部を収納スペース３としている。凹部の収納スペース３は、その内形を薄型電池５の外形よりもわずかに大きくしている。この収納スペース３は、薄型電池５を内側に配置する状態で、薄型電池５外周との間に狭い隙間、たとえば、１ｍｍ以下の隙間を設けている。電子機器１は、できる限り外形を小さくするために、内部の無駄なスペースを少なくしている。このことから、収納スペース３と薄型電池５外周との隙間もできる限り狭く、薄型電池５を挿入でき、かつできる限り小さく設計される。 The portable electronic device 1 shown in FIGS. 1 and 2 has a recess for storing the battery pack 4 inside the outer case 2, and the recess serves as a storage space 3. The recessed storage space 3 has an inner shape slightly larger than the outer shape of the thin battery 5. The storage space 3 is provided with a narrow gap, for example, a gap of 1 mm or less, between the thin battery 5 and the outer periphery of the thin battery 5 with the thin battery 5 disposed inside. The electronic device 1 has a small internal space in order to make the outer shape as small as possible. Therefore, the gap between the storage space 3 and the outer periphery of the thin battery 5 is also as narrow as possible, so that the thin battery 5 can be inserted and designed as small as possible.
　電池パック４の薄型電池５は、外形を四角形とする角形電池である。この電池パック４を配置する収納スペース３は四角形の凹部で、薄型電池５との間の隙間をできる限り狭くする状態で薄型電池５を挿入して、粘着シート６で固定できる形状とされる。 The thin battery 5 of the battery pack 4 is a rectangular battery having a rectangular outer shape. The storage space 3 in which the battery pack 4 is disposed is a quadrangular recess, and is shaped so that the thin battery 5 can be inserted and fixed with the adhesive sheet 6 with the gap between the battery pack 4 and the thin battery 5 as narrow as possible.
　粘着シート６は、透明のプラスチックフィルムである。透明の粘着シート６は、薄型電池５の表面の露出面５Ａに接着する状態で、表面の印刷文字や図形を外部から見ることができる。このため、印刷文字や図形を見える状態として、薄型電池５の表面に広い面積で接着できる。 The adhesive sheet 6 is a transparent plastic film. The transparent adhesive sheet 6 can see the printed characters and figures on the surface from the outside in a state where it adheres to the exposed surface 5A of the surface of the thin battery 5. For this reason, it can adhere to the surface of the thin battery 5 in a wide area in a state where the printed characters and figures can be seen.
　粘着シート６の展開図を図３と図９に示し、これ等の使用状態を図２～図１２に示している。これ等の図に示す粘着シート６は、接着層７を介して収納スペース３に接着される接着シート部８と、薄型電池表面の露出面５Ａに剥離自在に接着される剥離シート部９と、薄型電池５の背面５Ｂに接着されると共に、先端部には薄型電池５の露出面５Ａに突出してなるツマミ部１０Ａを有する摘みシート部１０とを有する。 Developed views of the pressure-sensitive adhesive sheet 6 are shown in FIGS. 3 and 9, and the state of use thereof is shown in FIGS. The adhesive sheet 6 shown in these drawings includes an adhesive sheet portion 8 that is adhered to the storage space 3 via an adhesive layer 7, a release sheet portion 9 that is releasably adhered to the exposed surface 5A of the thin battery surface, It is adhered to the back surface 5B of the thin battery 5 and has a knob sheet portion 10 having a knob portion 10A protruding from the exposed surface 5A of the thin battery 5 at the tip.
　接着シート部８は、接着層７を介して収納スペース３の底面に剥離しない状態で接着される。接着シート部８を収納スペース３の底面から剥離することなく、薄型電池５を収納スペース３から取り出しするからである。したがって、接着層７は、接着シート部８の下面を強く接着する接着剤層を介して収納スペース３の底面に接着され、あるいは強接着する粘着層を介して収納スペース３の底面に接着される。図１の断面図に示す粘着シート６は、接着層７を両面接着テープとし、この両面接着テープを介して接着シート部８を収納スペース３の底面に接着している。両面接着テープは、両面に強粘着層を有するテープで、一方の強粘着層を収納スペース３の底面に、他方の強粘着層を接着シート部８の下面に接着して、接着シート部８を収納スペース３に剥離しない状態で接着する。薄型電池５を収納スペース３から取り出すとき、接着シート部８は薄型電池５と一緒に剥離されずに収納スペース３に残存する。すなわち、両面接着テープの接着層７を剥離することなく、薄型電池５は収納スペース３から取り出される。したがって、接着層７の両面接着テープは、接着シート部８を収納スペース３の底面に接着して、摘みシート部１０を収納スペース３の底面に接着しない。 The adhesive sheet portion 8 is bonded to the bottom surface of the storage space 3 through the adhesive layer 7 without being peeled off. This is because the thin battery 5 is taken out from the storage space 3 without peeling the adhesive sheet portion 8 from the bottom surface of the storage space 3. Therefore, the adhesive layer 7 is adhered to the bottom surface of the storage space 3 via an adhesive layer that strongly adheres the lower surface of the adhesive sheet portion 8, or is adhered to the bottom surface of the storage space 3 via an adhesive layer that strongly adheres. . The pressure-sensitive adhesive sheet 6 shown in the cross-sectional view of FIG. 1 has a double-sided adhesive tape as the adhesive layer 7, and the adhesive sheet portion 8 is bonded to the bottom surface of the storage space 3 through the double-sided adhesive tape. The double-sided adhesive tape is a tape having a strong adhesive layer on both sides. One strong adhesive layer is adhered to the bottom surface of the storage space 3 and the other strong adhesive layer is adhered to the lower surface of the adhesive sheet portion 8 to attach the adhesive sheet portion 8. Adhere to the storage space 3 without peeling. When the thin battery 5 is taken out from the storage space 3, the adhesive sheet portion 8 remains in the storage space 3 without being peeled off together with the thin battery 5. That is, the thin battery 5 is taken out from the storage space 3 without peeling off the adhesive layer 7 of the double-sided adhesive tape. Therefore, the double-sided adhesive tape of the adhesive layer 7 bonds the adhesive sheet portion 8 to the bottom surface of the storage space 3 and does not bond the knob sheet portion 10 to the bottom surface of the storage space 3.
　図３、図４及び図９の粘着シート６は、接着シート部８に、接着層７を設ける接着領域１１を表示している。この粘着シート６は、接着領域１１に接着層７の両面接着テープを接着して、両面接着テープを接着シート部８にのみ接着できる。すなわち、接着層７の両面接着テープが摘みシート部１０にはみ出さないように接着できる。したがって、両面接着テープの強粘着層、すなわち接着層７が摘みシート部１０に強く接着されて、薄型電池５を取り出し難くすることがない。 3, 4, and 9, the adhesive sheet 6 displays an adhesive region 11 in which an adhesive layer 7 is provided on the adhesive sheet portion 8. The pressure-sensitive adhesive sheet 6 can be bonded only to the adhesive sheet portion 8 by bonding the double-sided adhesive tape of the adhesive layer 7 to the adhesive region 11. That is, the double-sided adhesive tape of the adhesive layer 7 can be bonded so that it does not protrude from the knob sheet portion 10. Therefore, the strong adhesive layer of the double-sided adhesive tape, that is, the adhesive layer 7 is strongly adhered to the picking sheet portion 10 and does not make it difficult to take out the thin battery 5.
　接着シート部８は、薄型電池５を収納スペース３から取り出す状態で、収納スペース３から剥離されない。すなわち、接着シート部８を収納スペース３に残して、摘みシート部１０と一緒に薄型電池５が収納スペース３から取り出される。薄型電池５が接着シート部８から分離して収納スペース３から取り出しできるように、接着シート部８は薄型電池５に剥離自在に接着される。 The adhesive sheet portion 8 is not peeled off from the storage space 3 in a state where the thin battery 5 is taken out from the storage space 3. That is, the thin battery 5 is taken out of the storage space 3 together with the knob sheet portion 10 while leaving the adhesive sheet portion 8 in the storage space 3. The adhesive sheet 8 is detachably bonded to the thin battery 5 so that the thin battery 5 can be separated from the adhesive sheet 8 and taken out from the storage space 3.
　粘着シート６は、図１の一部拡大図に示すように、薄型電池５との対向面に、接着層７よりも接着強度の弱い弱接着層１６を設けている。このような弱接着層１６として、接着層７よりも接着強度の弱い粘着層とすることができる。粘着層である弱接着層１６は、剥離自在に薄型電池５の表面に接着される。弱接着層１６は、薄型電池５との対向面の全面、すなわち、接着シート部８と剥離シート部９と摘みシート部１０とに設けられる。弱接着層１６は、薄型電池５の表面に剥離自在に接着されて、薄型電池５を収納スペース３に固定する。この粘着シート６は、薄型電池５の対向面の全面に弱接着層１６を設ける、すなわち、弱接着層１６を設ける領域と設けない領域とを区画する必要がないので、安価に多量生産できる。また、弱接着層１６を介して接着シート部８と剥離シート部９と摘みシート部１０とを薄型電池５の表面に広い面積で接着できるので、薄型電池５を確実に収納スペース３に固定できる。ただ、粘着シート６は、必ずしも全面に弱接着層１６を設ける必要はなく、たとえば、接着シート部８の薄型電池５との対向面に弱接着層を設けることなく、薄型電池５を収納スペース３に固定することもできる。薄型電池５に接着される剥離シート部９が接着シート部８に連続するので、剥離シート部９と接着シート部８とを介して薄型電池５を収納スペース３に固定できるからである。 As shown in the partially enlarged view of FIG. 1, the pressure-sensitive adhesive sheet 6 is provided with a weak adhesive layer 16 having a lower adhesive strength than the adhesive layer 7 on the surface facing the thin battery 5. Such a weak adhesive layer 16 can be an adhesive layer having a lower adhesive strength than the adhesive layer 7. The weak adhesive layer 16 that is an adhesive layer is adhered to the surface of the thin battery 5 in a peelable manner. The weak adhesive layer 16 is provided on the entire surface facing the thin battery 5, that is, on the adhesive sheet portion 8, the release sheet portion 9, and the knob sheet portion 10. The weak adhesive layer 16 is detachably bonded to the surface of the thin battery 5 to fix the thin battery 5 to the storage space 3. The pressure-sensitive adhesive sheet 6 can be mass-produced at low cost because it is not necessary to provide the weak adhesive layer 16 on the entire opposite surface of the thin battery 5, that is, to partition the area where the weak adhesive layer 16 is provided and the area where the weak adhesive layer 16 is not provided. Further, since the adhesive sheet portion 8, the release sheet portion 9, and the knob sheet portion 10 can be bonded to the surface of the thin battery 5 with a wide area via the weak adhesive layer 16, the thin battery 5 can be securely fixed to the storage space 3. . However, the adhesive sheet 6 does not necessarily need to be provided with the weak adhesive layer 16 on the entire surface. For example, the thin battery 5 is accommodated in the storage space 3 without providing the weak adhesive layer on the surface of the adhesive sheet portion 8 facing the thin battery 5. It can also be fixed to. This is because the release sheet portion 9 bonded to the thin battery 5 is continuous with the adhesive sheet portion 8, so that the thin battery 5 can be fixed to the storage space 3 via the release sheet portion 9 and the adhesive sheet portion 8.
　剥離シート部９は、接着シート部８に連続しており、薄型電池表面の露出面５Ａに剥離自在に接着されて、薄型電池５を収納スペース３に固定する。粘着シート６は、薄型電池５の露出面５Ａの両側に所定の幅で接着されて、薄型電池５を収納スペース３に固定する。図２と図１２の薄型電池５は、外周縁部（図において上縁）に凹部５Ｃを有し、剥離シート部９の一部を凹部５Ｃに非接着状態に配置している。この薄型電池５は、四角形の一辺に凹部５Ｃを設けて、ここに剥離シート部９の一端を配置している。リチウムポリマー電池は、四角形の一辺に凹部５Ｃができる。電極体の両側面に配置しているプラスチックフィルムを外周縁で積層し、積層部を加熱溶着して、電極リード１２を引き出して、内部を気密構造としているからである。剥離シート部９の端部を薄型電池５の凹部５Ｃに配置して、端部を薄型電池５の露出面５Ａに接着しない構造は、接着されない部分を摘んで簡単に薄型電池５の露出面５Ａから剥離できる。 The release sheet portion 9 is continuous to the adhesive sheet portion 8 and is peelably bonded to the exposed surface 5A of the thin battery surface to fix the thin battery 5 to the storage space 3. The adhesive sheet 6 is bonded to both sides of the exposed surface 5 </ b> A of the thin battery 5 with a predetermined width to fix the thin battery 5 to the storage space 3. The thin battery 5 of FIGS. 2 and 12 has a recess 5C at the outer peripheral edge (upper edge in the figure), and a part of the release sheet portion 9 is disposed in a non-adhered state in the recess 5C. This thin battery 5 is provided with a recess 5 </ b> C on one side of a square, and one end of the release sheet portion 9 is disposed here. The lithium polymer battery has a recess 5C on one side of the quadrangle. This is because the plastic films arranged on both side surfaces of the electrode body are laminated at the outer peripheral edge, the laminated portion is heated and welded, the electrode lead 12 is pulled out, and the inside has an airtight structure. In the structure in which the end portion of the release sheet portion 9 is disposed in the concave portion 5C of the thin battery 5 and the end portion is not adhered to the exposed surface 5A of the thin battery 5, the exposed surface 5A of the thin battery 5 can be easily obtained by picking the unbonded portion. Can be peeled off.
　摘みシート部１０は、ここを引っ張って薄型電池５を収納スペース３から取り出すので、薄型電池５の背面５Ｂに接着部１０Ｂを接着して、先端部には薄型電池５の露出面５Ａに突出するツマミ部１０Ａを設けている。接着部１０Ｂは、ツマミ部１０Ａを引っ張って薄型電池５から剥離しない強度で薄型電池５の背面５Ｂに接着される。接着部１０Ｂは、薄型電池５の背面５Ｂとの接着力が接着層７よりも弱くても、ツマミ部１０Ａを引っ張って薄型電池５を取り出す状態で、薄型電池５から剥離することはない。ツマミ部１０Ａを引っ張る状態で、接着部１０Ｂには接着面と平行に引張力が作用して、接着部１０Ｂを剥離する方向に引張力が作用しないからである。したがって、摘みシート部１０は、粘着シート６の剥離面全面に設けられる弱接着層１６で薄型電池５に接着されて、ツマミ部１０Ａを引っ張って、薄型電池５を収納スペース３から取り出すことができる。 The picking sheet portion 10 pulls here to take out the thin battery 5 from the storage space 3. Therefore, the adhesive portion 10 </ b> B is adhered to the back surface 5 </ b> B of the thin battery 5, and the tip portion protrudes from the exposed surface 5 </ b> A of the thin battery 5. A knob portion 10A is provided. The bonding portion 10B is bonded to the back surface 5B of the thin battery 5 with a strength that does not peel off the thin battery 5 by pulling the knob portion 10A. Even if the adhesive force with the back surface 5B of the thin battery 5 is weaker than that of the adhesive layer 7, the adhesive part 10B does not peel from the thin battery 5 in a state where the thin battery 5 is taken out by pulling the knob part 10A. This is because, in a state where the knob portion 10A is pulled, a tensile force acts on the bonding portion 10B in parallel with the bonding surface, and no tensile force acts in a direction in which the bonding portion 10B is peeled off. Therefore, the knob sheet portion 10 is adhered to the thin battery 5 by the weak adhesive layer 16 provided on the entire peeling surface of the pressure-sensitive adhesive sheet 6, and the thin battery 5 can be taken out from the storage space 3 by pulling the knob portion 10 </ b> A. .
　図２～図８に示す粘着シート６は、薄型電池表面の露出面５Ａの両側縁部に剥離シート部９を接着して、剥離シート部９の接着領域以外の領域である、図において露出面５Ａの下部にツマミ部１０Ａを剥離自在に接着している。図９～図１２の粘着シート６は、薄型電池表面の露出面５Ａの全面に剥離シート部９とツマミ部１０Ａとを接着している。この粘着シート６は、剥離シート部９と摘みシート部１０との間にミシン目１５を設けて切り離しできるようにして、露出面５Ａの両側部に剥離シート部９を、剥離シート部９の間と下部とに摘みシート部１０を設けている。 The adhesive sheet 6 shown in FIGS. 2 to 8 is a region other than the adhesive region of the release sheet portion 9 by bonding the release sheet portion 9 to both side edges of the exposed surface 5A of the thin battery surface. A knob portion 10A is detachably bonded to the lower portion of 5A. The adhesive sheet 6 of FIGS. 9 to 12 has the release sheet portion 9 and the knob portion 10A bonded to the entire exposed surface 5A of the thin battery surface. The pressure-sensitive adhesive sheet 6 is provided with a perforation 15 between the release sheet portion 9 and the knob sheet portion 10 so as to be separated, and the release sheet portions 9 are provided on both sides of the exposed surface 5A. A tab sheet portion 10 is provided at the bottom and the bottom.
　図４に示す粘着シート６は弱接着層を介して薄型電池５の背面５Ｂの全面に接着され、図９の粘着シート６は、弱接着層を介して薄型電池５の露出面５Ａの全面に接着される。図４の粘着シート６は、薄型電池５の背面５Ｂの全面に接着される部分には、摘みシート部１０と接着シート部８との間にミシン目１３を設けて分離自在に連結している。さらに、この図の粘着シート６は、摘みシート部１０の両側を切断ライン１４で切り離して、図において摘みシート部１０の上縁に沿ってミシン目１３を設けている。図示しないが、この粘着シートは切断ラインを設けている部分をミシン目とすることができ、またミシン目を切断ラインとすることもできる。 The adhesive sheet 6 shown in FIG. 4 is adhered to the entire surface of the back surface 5B of the thin battery 5 via the weak adhesive layer, and the adhesive sheet 6 of FIG. 9 is adhered to the entire exposed surface 5A of the thin battery 5 via the weak adhesive layer. Glued. The adhesive sheet 6 shown in FIG. 4 has a perforation 13 provided between the knob sheet portion 10 and the adhesive sheet portion 8 at the portion to be bonded to the entire back surface 5B of the thin battery 5 and is connected in a separable manner. . Furthermore, the pressure-sensitive adhesive sheet 6 in this figure is provided with a perforation 13 along the upper edge of the knob sheet portion 10 in the figure by cutting off both sides of the knob sheet portion 10 with a cutting line 14. Although not shown in the figure, this adhesive sheet can have a perforation at a portion where a cutting line is provided, and can also be a perforation line as a cutting line.
　図４の粘着シート６は、弱接着層を薄型電池５の表面に接着して、すなわち、接着シート部８と剥離シート部９と摘みシート部１０とを薄型電池５の表面に接着し、接着領域１１に接着層７である両面接着テープを接着し、両面接着テープを介して薄型電池５を電子機器１の収納スペース３に固定される。 The pressure-sensitive adhesive sheet 6 in FIG. 4 has a weak adhesive layer adhered to the surface of the thin battery 5, that is, the adhesive sheet portion 8, the release sheet portion 9, and the knob sheet portion 10 are adhered to the surface of the thin battery 5. A double-sided adhesive tape as the adhesive layer 7 is bonded to the region 11, and the thin battery 5 is fixed to the storage space 3 of the electronic device 1 through the double-sided adhesive tape.

　なお、本実施例において、電子機器１を携帯型の電子機器としたが、携帯式以外の電子機器、例えば、デスクトップパソコンやハードディスクレコーダーなどの据置型の電子機器で、内蔵電池を備えるものとしてもよい。 In the present embodiment, the electronic device 1 is a portable electronic device. However, the electronic device 1 may be a non-portable electronic device, for example, a stationary electronic device such as a desktop personal computer or a hard disk recorder, and provided with a built-in battery. Good.

The weak adhesive layer 16 is an adhesive that adheres the adhesive sheet 6 and the storage space 3. An adhesive layer having a lower adhesive strength than that of the layer 7 may be used. Alternatively, the weak adhesive layer is a layer that can hold the pressure-sensitive adhesive sheet 6 and the thin battery 5 in a close contact state, for example, a contact layer made of gel or liquid that can hold the pressure-sensitive adhesive sheet 6 and the thin battery 5 in a close contact state by surface tension. Or it can also be set as the vacuum contact | adherence layer which adhere | attaches the adhesive sheet 6 and the thin battery 5 in a vacuum state.
　以上の電池パックは、図７に示すように、ツマミ部１０Ａを引っ張って、図８に示すように収納スペース３から取り出される。電池パック４が収納スペース３から取り出された状態で、薄型電池５の接着シート部８との接着部表面に歪みができることがある。歪みのある薄型電池は再使用できないので、剥離するときには歪みが発生させないことが大切である。歪みは、ツマミ部１０Ａを引っ張って電池パック４を収納スペース３から分離するときに、薄型電池表面が接着シート部８に密着されてスムーズに剥離できず、接着シート部８に強く引っ張られて延びることが原因で発生する。薄型電池５は、図１に示すように、スムーズに剥離できるように、接着力の弱い弱接着層１６を介して接着シート部８に接着している。にもかかわらず、薄型電池５はスムーズに接着シート部８から剥離されない。それは、薄型電池５の表面が弱接着層１６によって接着シート部８に吸盤のように吸着状態で密着しているからである。この状態で接着される薄型電池５は、弱接着層１６の接着力（粘着層にあっては粘着力）と、吸盤が空気を排気して吸着する吸着力との両方で接着される。接着力は接着層の接着強度で弱くできるが、吸着力は接着層の接着力では弱くできない。吸着力は、薄型電池と接着シート部との間の空気層によってコントロールできる。 The above battery pack is taken out from the storage space 3 as shown in FIG. 8 by pulling the knob portion 10A as shown in FIG. In a state where the battery pack 4 is taken out from the storage space 3, there may be a case where the surface of the adhesive portion with the adhesive sheet portion 8 of the thin battery 5 can be distorted. Since a strained thin battery cannot be reused, it is important not to cause distortion when peeling. When the battery pack 4 is separated from the storage space 3 by pulling the knob portion 10A, the surface of the thin battery is brought into close contact with the adhesive sheet portion 8 and cannot be peeled off smoothly, and is stretched by being strongly pulled by the adhesive sheet portion 8. It is caused by that. As shown in FIG. 1, the thin battery 5 is bonded to the adhesive sheet portion 8 via a weak adhesive layer 16 having a weak adhesive force so that it can be smoothly peeled off. Nevertheless, the thin battery 5 is not smoothly peeled off from the adhesive sheet portion 8. This is because the surface of the thin battery 5 is in close contact with the adhesive sheet portion 8 in an adsorbed state like a suction cup by the weak adhesive layer 16. The thin battery 5 bonded in this state is bonded by both the adhesive force of the weak adhesive layer 16 (adhesive force in the case of the adhesive layer) and the adsorption force by which the suction cup exhausts and adsorbs air. The adhesive force can be weakened by the adhesive strength of the adhesive layer, but the adsorption force cannot be weakened by the adhesive force of the adhesive layer. The adsorption force can be controlled by an air layer between the thin battery and the adhesive sheet portion.
　図１４は、ツマミ部１０Ａを引っ張って電池パック４が収納スペース３から取り出される状態を示す拡大断面図である。この図は、図２のＩ－Ｉ線の断面に相当する拡大断面図であって、薄型電池５の背面５Ｂを収納スペース３に接着する部分の拡大断面図である。図１４の鎖線は、薄型電池５を収納スペース３から取り出した状態を示している。鎖線で示すように、薄型電池５は摘みシート部１０の接着部１０Ｂを背面５Ｂに接着して、接着シート部８を収納スペース３に残して、すなわち摘みシート部１０の接着部１０Ｂを接着シート部８から切り離して収納スペース３から取り出される。薄型電池５は、接着シート部８との間の弱接着層１６を剥離して収納スペース３から取り出される。ツマミ部１０Ａを引っ張って薄型電池５を接着シート部８の弱接着層１６から剥離するとき、図１４のジグザグ線Ａで示す弱接着層１６の接合面が強く接着されて、スムーズに剥離されない。ジグザグ線Ａで示す弱接着層１６の接合面が、弱接着層１６の接着力と吸着力の両方で強く接着されるからである。このため、収納スペース３から取り出された薄型電池５は、図の鎖線で示すように、接合面で強く引っ張られて延びて歪み２０が発生する。 FIG. 14 is an enlarged cross-sectional view showing a state where the battery pack 4 is taken out from the storage space 3 by pulling the knob portion 10A. This figure is an enlarged sectional view corresponding to the section taken along the line II of FIG. 2, and is an enlarged sectional view of a portion where the back surface 5B of the thin battery 5 is bonded to the storage space 3. FIG. A chain line in FIG. 14 shows a state in which the thin battery 5 is taken out from the storage space 3. As indicated by the chain line, the thin battery 5 has the adhesive portion 10B of the knob sheet portion 10 bonded to the back surface 5B, and the adhesive sheet portion 8 is left in the storage space 3, that is, the adhesive portion 10B of the knob sheet portion 10 is bonded to the adhesive sheet. It is separated from the portion 8 and taken out from the storage space 3. The thin battery 5 is taken out of the storage space 3 by peeling off the weak adhesive layer 16 between the thin battery 5 and the adhesive sheet portion 8. When the thin battery 5 is peeled from the weak adhesive layer 16 of the adhesive sheet portion 8 by pulling the knob portion 10A, the joint surface of the weak adhesive layer 16 indicated by the zigzag line A in FIG. 14 is strongly bonded and not smoothly peeled off. This is because the joint surface of the weak adhesive layer 16 indicated by the zigzag line A is strongly bonded by both the adhesive force and the adsorption force of the weak adhesive layer 16. For this reason, the thin battery 5 taken out from the storage space 3 is stretched by being strongly pulled at the joint surface, as shown by the chain line in the figure, and distortion 20 is generated.
　図１５の斜視図と図１６の拡大断面図に示す粘着シート６は、以上の弊害を防止するために、薄型電池５と接着シート部８との間に、弱接着層１６を設けない弱接着材の非塗布領域１７を設けている。非塗布領域１７は、薄型電池５との対向面であって、接着層７の反対側の面（図１６において接着シート部８の上面）に設けられる。非塗布領域１７は、薄型電池５を接着シート部８の表面に吸着させない空気層となる。弱接着層１６の間に非塗布領域１７を設けているので、非塗布領域１７には弱接着層１６の膜厚に相当する隙間ができるからである。非塗布領域１７は、空気層となって薄型電池５を接着シート部８の表面に吸着しない。また、弱接着層１６が接着することもない。したがって、接着シート部８は、弱接着層１６を介して薄型電池５の表面に接着されるが、非塗布領域１７においては薄型電池５に接着されない。 The pressure-sensitive adhesive sheet 6 shown in the perspective view of FIG. 15 and the enlarged cross-sectional view of FIG. 16 has a weak adhesion in which the weak adhesion layer 16 is not provided between the thin battery 5 and the adhesion sheet portion 8 in order to prevent the above-described adverse effects. A material non-application area 17 is provided. The non-application area | region 17 is a surface facing the thin battery 5, Comprising: It is provided in the surface on the opposite side of the contact bonding layer 7 (upper surface of the adhesive sheet part 8 in FIG. 16). The non-application area 17 becomes an air layer that does not allow the thin battery 5 to be adsorbed on the surface of the adhesive sheet portion 8. This is because the non-application area 17 is provided between the weak adhesion layers 16, and therefore a gap corresponding to the film thickness of the weak adhesion layer 16 is formed in the non-application area 17. The non-application area 17 becomes an air layer and does not adsorb the thin battery 5 to the surface of the adhesive sheet portion 8. Further, the weak adhesive layer 16 does not adhere. Therefore, the adhesive sheet portion 8 is adhered to the surface of the thin battery 5 through the weak adhesive layer 16, but is not adhered to the thin battery 5 in the non-application region 17.
　図１６の断面図に示す粘着シート６は、接着シート部８において、接着層７の反対側の面（図において接着シート部８の上面）であって、薄型電池５との対向面に非塗布領域１７を設けている。この粘着シート６の展開図を図１７に示す。この粘着シート６は、細長い接着層７の長手方向に延びて、所定の幅の帯状の非塗布領域１７を設けている。なお、図１７においては、非塗布領域１７をわかりやすくするために、弱接着層１６を設けた部分を灰色のハッチングで表示している。非塗布領域１７の横幅（Ｗ１）は接着層７の横幅（Ｗ２）よりも狭く、接着層７は非塗布領域１７の外側に配置される。この粘着シート６は、図１６に示すように、非塗布領域１７の両側に設けられる弱接着層１６を薄型電池５に接着する。以上のように、非塗布領域１７の横幅（Ｗ１）を接着層７の横幅（Ｗ２）よりも狭くして、接着層７の幅方向に対して内側に非塗布領域１７を設ける粘着シート６は、非塗布領域１７の両側に設けられる弱接着層１６を薄型電池５に接着して、この部分を接着層７を介して収納スペース３に接着する。 The adhesive sheet 6 shown in the cross-sectional view of FIG. 16 is a surface opposite to the adhesive layer 7 in the adhesive sheet portion 8 (the upper surface of the adhesive sheet portion 8 in the figure), and is not applied to the surface facing the thin battery 5. Region 17 is provided. A developed view of the pressure-sensitive adhesive sheet 6 is shown in FIG.

The lateral width (W 1) of the non-application area 17 is narrower than the lateral width (W 2) of the adhesive layer 7, and the adhesive layer 7 is disposed outside the non-application area 17. As shown in FIG. 16, the pressure-sensitive adhesive sheet 6 adheres the weak adhesive layer 16 provided on both sides of the non-application area 17 to the thin battery 5. As described above, the pressure-sensitive adhesive sheet 6 in which the width (W1) of the non-application region 17 is narrower than the width (W2) of the adhesive layer 7 and the non-application region 17 is provided on the inner side with respect to the width direction of the adhesive layer 7 is The weak adhesive layer 16 provided on both sides of the non-application area 17 is adhered to the thin battery 5, and this portion is adhered to the storage space 3 through the adhesive layer 7.

However, although not shown, the pressure-sensitive adhesive sheet is not necessarily provided with the non-application region 17 on the inner side with respect to the width direction of the adhesive layer 7 and the adhesive layer 7 need to be disposed on both sides of the non-application region 17 as described above. Alternatively, a non-application area can be provided on one side of the adhesive layer.

This knob portion 10 </ b> A has a feature that the peeling portion 18 can be picked and the picking sheet portion 10 can be quickly peeled from the thin battery 5.
　以上の粘着シート６は、図１８に示すように、細長い帯状のプラスチックシート１９を、太線で示す形状に裁断して製作される。なお、図１８においても、非塗布領域１７をわかりやすくするために、弱接着層１６を設けた部分を灰色のハッチングで表示している。図１７の展開図に示す粘着シート６は、図１８に示す帯状のプラスチックシート１９を裁断して、能率よく安価に多量生産しながら、ツマミ部１０Ａの先端に剥離部１８を設けることができる。それは、ツマミ部１０Ａ先端の剥離部１８を、直線状に設けている非塗布領域１７の延長線上に配置するので、プラスチックシート１９を裁断してツマミ部１０Ａの先端に剥離部１８を設けることができるからである。 The above adhesive sheet 6 is produced by cutting an elongated strip-shaped plastic sheet 19 into a shape indicated by a thick line, as shown in FIG. Also in FIG. 18, in order to make the non-application area 17 easy to understand, the portion provided with the weak adhesive layer 16 is displayed in gray hatching.
