Description

本発明は、樹脂封止型受光素子と、樹脂封止型受光素子を囲んで電磁シールドを行うシールドケースとを備える遠隔制御用受光装置、およびこのような遠隔制御用受光装置を備える電子機器に関する。   The present invention relates to a remote-control light-receiving device including a resin-sealed light-receiving element and a shield case that surrounds the resin-sealed light-receiving element and performs electromagnetic shielding, and an electronic apparatus including such a remote-control light-receiving device. .

リモコン送信機（リモートコントローラ）と呼ばれる遠隔制御用送信装置（遠隔制御用発光装置）から送信された赤外光信号を受信する遠隔制御用受信装置（以下、遠隔制御用受光装置と言う）においては、受光素子（ホトダイオードチップ（以下、ＰＤチップと言う））によって、リモコン送信機から送信された赤外光信号を受信する。   In a remote control receiver (hereinafter referred to as a remote control light receiving device) that receives an infrared light signal transmitted from a remote control transmitter (remote control light emitting device) called a remote control transmitter (remote controller) The infrared light signal transmitted from the remote control transmitter is received by the light receiving element (photodiode chip (hereinafter referred to as PD chip)).

そして、受信した赤外光信号に対して信号制御処理用素子（以下、ＩＣチップと言う）によって増幅および波形整形等の各種の信号処理を行い、受信した赤外光信号に応答して各種のオーディオヴィジュアル機器（例：ＴＶ受像機、ＶＴＲ等）、オフィスオートメーション機器（例：パーソナルコンピューター等）の遠隔制御が行なわれる。   The received infrared light signal is subjected to various signal processing such as amplification and waveform shaping by a signal control processing element (hereinafter referred to as an IC chip), and various signals are processed in response to the received infrared light signal. Remote control of audio-visual equipment (eg, TV receiver, VTR, etc.) and office automation equipment (eg, personal computer, etc.) is performed.

リモコン送信機から送信される赤外光信号（デジタル信号）は、ＰＤチップの受光面で受光され、受光された光信号は微弱な電気信号に変換される。そして、微弱な電気信号はＩＣチップ内の増幅回路によって数万倍に増幅され、増幅された電気信号は必要な周波数帯域の信号のみを抽出するフィルタ回路（バンドパスフィルタ（ＢＰＦ））で必要な信号の周波数のみが抽出される。その後、検波回路によって赤外光信号と同様のデジタル信号情報として出力される。   An infrared light signal (digital signal) transmitted from the remote control transmitter is received by the light receiving surface of the PD chip, and the received light signal is converted into a weak electric signal. The weak electric signal is amplified tens of thousands of times by an amplifier circuit in the IC chip, and the amplified electric signal is necessary for a filter circuit (band pass filter (BPF)) that extracts only a signal in a necessary frequency band. Only the frequency of the signal is extracted. Thereafter, it is output as digital signal information similar to the infrared light signal by the detection circuit.

上述した遠隔制御用受光装置は、ＰＤチップとＩＣチップとをリードフレーム上に搭載固着した後、モールド樹脂によって封止することによって形成され、いわゆる複数チップ型受光部品を構成する。   The above-described remote control light-receiving device is formed by mounting and fixing a PD chip and an IC chip on a lead frame and then sealing with a mold resin to constitute a so-called multi-chip type light-receiving component.

また、遠隔制御用受光装置としては、モールド樹脂を外側から金属製ケースによって覆った外部シールド型と、モールド樹脂の内側でＰＤチップおよびＩＣチップをリードフレームで覆った内部シールド型とがある。一般的に、遠隔制御用受光装置の機能として１０ｍ以上の遠隔制御距離が要請されている。したがって、シールド形態に関係なく微弱な電気信号を増幅するために数万倍の信号増幅処理を行なっている。   As remote control light receiving devices, there are an external shield type in which a mold resin is covered with a metal case from the outside, and an internal shield type in which a PD chip and an IC chip are covered with a lead frame inside the mold resin. Generally, a remote control distance of 10 m or more is required as a function of the remote control light receiving device. Therefore, signal amplification processing of tens of thousands of times is performed to amplify a weak electric signal regardless of the shield form.

遠隔制御用受光装置では、非常に高い増幅率での信号処理を施すことから、電磁ノイズ等の信号以外のノイズ成分も増幅回路によって増幅されてしまい、信号とノイズとの強弱の比（ＳＮ比）が確保できなくなり、結果的に必要な信号のみを抽出することができなくなってしまう。   Since the remote control light-receiving device performs signal processing with a very high amplification factor, noise components other than signals such as electromagnetic noise are also amplified by the amplifier circuit, and the signal-to-noise ratio (SN ratio). ) Cannot be secured, and as a result, only necessary signals cannot be extracted.

したがって、ＳＮ比を改善するために、上述したとおり、金属製のシールドケース等でＰＤチップ、ＩＣチップ、およびその周辺を覆って、電磁シールドを施すことが行われている。   Therefore, in order to improve the SN ratio, as described above, an electromagnetic shield is applied by covering the PD chip, the IC chip, and the periphery thereof with a metal shield case or the like.

モールド樹脂を覆う金属シールドケースは製品単品（１個の遠隔制御用受光装置）状態ではモールド樹脂を覆うのみであり、リードフレームのＧＮＤ端子部分のリードとは繋がっておらず、ユーザ側で基板に実装する際にリードフレームのＧＮＤリード部と金属シールドケースとを基板上のパターンを介して同電位に繋ぐのが一般的である。   The metal shield case that covers the mold resin only covers the mold resin in a single product (one remote control light receiving device) state, and is not connected to the lead of the GND terminal portion of the lead frame, and is not connected to the substrate on the user side. When mounting, the GND lead portion of the lead frame and the metal shield case are generally connected to the same potential via a pattern on the substrate.

なお、製品単品状態でＧＮＤリード部と金属シールドケースとを導通させた構造のものがあった。しかしながら、半田付けで導通処理を施す必要がある等の附加作業が必要であるためコストアップの要因となり、単品状態で金属シールドケースを搭載した製品では非導通が主流を占めている。   There is a structure in which the GND lead portion and the metal shield case are electrically connected in a single product state. However, additional work such as the need for conducting treatment by soldering is necessary, which increases costs, and non-conduction is dominant in products with a metal shield case in a single product state.

図６Ａ、図６Ｂ、図７に基づいて従来の遠隔制御用受光装置について説明する。   A conventional remote control light-receiving device will be described with reference to FIGS. 6A, 6B, and 7. FIG.

図６Ａは、従来の樹脂封止型受光素子を製造過程で多連状としている状態を示す説明図であり、平面図および側面図を併せて示してある。   FIG. 6A is an explanatory view showing a state in which a conventional resin-encapsulated light receiving element is formed in a multiple shape in the manufacturing process, and a plan view and a side view are shown together.

従来の樹脂封止型受光素子１１０は、リード部１１５と、受光素子チップ（不図示）が搭載されたリード部１１５の先端を樹脂封止する樹脂封止部１１６とを備える。樹脂封止部１１６には、例えば受光した赤外光を集光するレンズ部１１７が形成されている。
樹脂封止型受光素子１１０は、ガイドフレーム１１１によって多連状に繋がれている。 A conventional resin-sealed light receiving element 110 includes a lead portion 115 and a resin sealing portion 116 that resin-seales the tip of the lead portion 115 on which a light receiving element chip (not shown) is mounted. In the resin sealing portion 116, for example, a lens portion 117 that collects received infrared light is formed.
The resin-sealed light receiving elements 110 are connected in a multiple manner by a guide frame 111.

図６Ｂは、従来の遠隔制御用受光装置を製造過程で多連状としている状態を示す説明図であり、平面図および側面図を併せて示してある。   FIG. 6B is an explanatory view showing a state in which a conventional remote control light-receiving device is formed in a multiple form in the manufacturing process, and a plan view and a side view are shown together.

従来の遠隔制御用受光装置１０１は、樹脂封止型受光素子１１０にシールドケース１３０を被せた形態としてある。シールドケース１３０は、樹脂封止部１１６のレンズ部１１７の側からレンズ部１１７を覆うように装着される。シールドケース１３０は、爪部１３０ｐを樹脂封止部１１６の方へ折り曲げてかしめることによって樹脂封止部１１６に対して固定される。したがって、小さい寸法で形成された爪部１３０ｐに対する「かしめ」作業が必要とされる。   The conventional remote control light receiving device 101 is configured such that a shield case 130 is placed on a resin-sealed light receiving element 110. The shield case 130 is mounted so as to cover the lens unit 117 from the lens unit 117 side of the resin sealing unit 116. The shield case 130 is fixed to the resin sealing portion 116 by bending and crimping the claw portion 130p toward the resin sealing portion 116. Therefore, a “caulking” operation for the claw portion 130p formed with a small size is required.

遠隔制御用受光装置１０１は、金属製のシールドケース１３０で樹脂封止部１１６の部分を包囲することによって、電磁ノイズに対して耐性を確保している。   The remote control light receiving device 101 secures resistance against electromagnetic noise by surrounding the resin sealing portion 116 with a metal shield case 130.

図７は、従来の遠隔制御用受光装置の完成状態を示す説明図であり、平面図、正面図、側面図を併せて示してある。   FIG. 7 is an explanatory view showing a completed state of a conventional remote control light-receiving device, and shows a plan view, a front view, and a side view.

遠隔制御用受光装置１０１は、リードフレーム１１１から個々に分離されて、完成状態（単品状態）となる。つまり、遠隔制御用受光装置１０１は、樹脂封止型受光素子１１０およびシールドケース１３０を備え、入出力端子としてのリード部１１５が外部へ導出されている。   The remote control light receiving device 101 is individually separated from the lead frame 111 to be in a completed state (single product state). That is, the remote control light receiving device 101 includes a resin-sealed light receiving element 110 and a shield case 130, and lead portions 115 serving as input / output terminals are led out to the outside.

電子部品の生産においては、低コスト化、量産化等の効率的な生産の観点から、自動製造装置への対応や海外生産展開が一般的になってきている。したがって、遠隔制御用受光装置１０１に対しても同様に生産の効率化が求められている。   In the production of electronic components, from the viewpoint of efficient production such as cost reduction and mass production, it has become common to deal with automatic manufacturing equipment and overseas production development. Therefore, the remote control light receiving device 101 is also required to increase the production efficiency.

しかしながら、従来の遠隔制御用受光装置１０１では、金属製のシールドケース１３０のケーシング（図６Ｂで、樹脂封止型受光素子１１０にシールドケース１３０を固定する過程）は、細部に関する「かしめ」により実行されている。したがって、生産性を向上させるという効率化の観点からは、一定の限界があり、また、効率化を推進する上でネックとなっていた。つまり、遠隔制御用受光装置１０１をさらに効率的に生産するために、効率的なケーシング方法が求められている。   However, in the conventional remote control light receiving device 101, the casing of the metal shield case 130 (the process of fixing the shield case 130 to the resin-sealed light receiving element 110 in FIG. 6B) is performed by “caulking” regarding details. Has been. Therefore, there is a certain limit from the viewpoint of efficiency improvement to improve productivity, and it has become a bottleneck in promoting efficiency improvement. That is, in order to produce the remote control light receiving device 101 more efficiently, an efficient casing method is required.

また、従来、ＴＶ受像機、ＡＶ機器、エアコン等の大型の電子機器では、遠隔制御用受光装置は電子機器内部での取り付け位置と電子機器の表面に形成された受光窓の位置との間で長い距離があることから遠隔制御用受光装置に対する要求はそれほど厳しくはなかった。また、カメラ、ムービー、カーオーディオなど限られた用途でのみ面実装パッケージ品（面実装部品）が使われていた。   Conventionally, in a large electronic device such as a TV receiver, an AV device, and an air conditioner, the remote control light receiving device is located between the mounting position inside the electronic device and the position of the light receiving window formed on the surface of the electronic device. Due to the long distance, the demand for the remote control light receiving device was not so strict. In addition, surface mount package products (surface mount components) were used only for limited applications such as cameras, movies, and car audio.

しかし、最近のＴＶ受像機の薄型化に伴い、完成品全体の大きさをできるだけ小さくする必要があり、適用される遠隔制御用受光装置に対しても薄型化の要望が増えている。また、生産ラインの自動化を容易に進めるために遠隔制御用受光装置に対しても面実装部品の形状とする要望が増えてきている。   However, with the recent thinning of TV receivers, it is necessary to reduce the overall size of the finished product as much as possible, and there is an increasing demand for thinning the applied remote control light receiving device. Further, in order to facilitate the automation of the production line, there is an increasing demand for the shape of the surface mount component for the remote control light receiving device.

また、従来例として示した遠隔制御用受光装置では、樹脂封止型受光素子はレンズ部を有していることから、シールドケースと樹脂封止型受光素子との間での位置決めはレンズ部によって実行されている。しかし、遠隔制御用受光装置（樹脂封止型受光素子）に対する薄型化の要請があることから、レンズ部を有しない樹脂封止型受光素子に対しても容易かつ高精度にシールドケースの位置決めをできる構成とする必要が生じている。   Further, in the remote control light receiving device shown as the conventional example, since the resin-sealed light receiving element has a lens portion, positioning between the shield case and the resin-sealed light receiving element is performed by the lens portion. It is running. However, since there is a demand for thinning of the remote control light receiving device (resin-sealed light receiving element), the shield case can be easily and accurately positioned even for the resin-sealed light receiving element having no lens portion. There is a need to be able to configure.

また、完成品の薄型化に伴い、レンズを有しない薄型形状の遠隔制御用受光装置（樹脂封止型受光素子）が求められている。したがって、レンズを有さない樹脂封止型受光素子に対するシールドケースの位置決めを容易に行える遠隔制御用受光装置が求められている。   In addition, as a finished product is made thinner, a thin-shaped remote control light-receiving device (resin-sealed light-receiving element) without a lens is required. Accordingly, there is a need for a remote control light-receiving device that can easily position the shield case with respect to a resin-sealed light-receiving element that does not have a lens.

また、部品構造の簡素化による生産性の向上、製造工程の簡略化による製造工数の削減による生産コストの低減が要求されている。   Further, there is a demand for improvement in productivity by simplifying the part structure and reduction in production cost by reducing the number of manufacturing steps by simplifying the manufacturing process.

つまり、先端面対向延長部３２ｐは、折り曲げられて裏面１６ｒに対向し、第１嵌合部３３および第２嵌合部３６は、相互に嵌合させてある。   That is, the front end surface opposing extension portion 32p is bent and faces the back surface 16r, and the first fitting portion 33 and the second fitting portion 36 are fitted to each other.

この構成により、第１嵌合部３３および第２嵌合部３６を相互に嵌合させるという簡単な構造で、シールドケース３０を樹脂封止部１６に容易かつ高精度に取り付けることが可能となり、シールドケース３０をかしめる作業が不要となることから、シールドケース３０を樹脂封止部１６に容易かつ高精度に取り付けることが可能となり、組み立て精度の高い遠隔制御用受光装置１を生産性良く安価に製造することができる。   With this configuration, the shield case 30 can be easily and accurately attached to the resin sealing portion 16 with a simple structure in which the first fitting portion 33 and the second fitting portion 36 are fitted to each other. Since the operation of caulking the shield case 30 is not required, the shield case 30 can be easily and highly accurately attached to the resin sealing portion 16, and the remote control light-receiving device 1 with high assembly accuracy is inexpensive with high productivity. Can be manufactured.

なお、本実施の形態では、樹脂封止型受光素子１０は、リードフレーム１１に実装された受光素子チップ１２および集積回路チップ１３を備える。受光素子チップ１２は、金属製のリードフレーム１１（例：鉄合金）に、絶縁性接着剤１２ｂを介して接着される。集積回路チップ１３は、リードフレーム１１に導電性接着剤１３ｂで接着されている。受光素子チップ１２は、例えばホトダイオード（ＰＤ）で構成される。   In the present embodiment, the resin-sealed light receiving element 10 includes a light receiving element chip 12 and an integrated circuit chip 13 mounted on a lead frame 11. The light receiving element chip 12 is bonded to a metal lead frame 11 (eg, iron alloy) via an insulating adhesive 12b. The integrated circuit chip 13 is bonded to the lead frame 11 with a conductive adhesive 13b. The light receiving element chip 12 is configured by, for example, a photodiode (PD).

受光素子チップ１２は、通常ＰＮ接合構造を有しており、遠隔制御用受光装置１の場合には逆電圧を掛けることから、受光素子チップ１２の裏面側のＮ電極部分に電位が生ずる。したがって、リードフレーム１１の構造上ＧＮＤ電位となる受光素子チップ１２を搭載した領域部分と受光素子チップ１２を搭載した領域部分との間は絶縁状態に保っておく必要があり、リードフレーム１１と受光素子チップ１２との接着には絶縁性フィラーを含んだエポキシ樹脂（絶縁性接着剤１２ｂ）を用いる。   The light receiving element chip 12 normally has a PN junction structure, and in the case of the remote control light receiving device 1, a reverse voltage is applied, so that a potential is generated at the N electrode portion on the back side of the light receiving element chip 12. Therefore, it is necessary to keep an insulating state between the region portion where the light receiving element chip 12 having the GND potential is mounted due to the structure of the lead frame 11 and the region portion where the light receiving element chip 12 is mounted. An epoxy resin (insulating adhesive 12b) containing an insulating filler is used for bonding to the element chip 12.

集積回路チップ１３は、表面で信号処理することから、裏面は、信号処理による影響が無い。したがって、リードフレーム１１との接着は導電性接着剤１３ｂであっても絶縁性接着剤１２ｂのような絶縁性接着剤であっても良い。通常は、作業性に優れて接着力がある導電性接着剤１３ｂ（エポキシ樹脂にＡｇ粉を混ぜ合わせた接着剤等）を使用する。   Since the integrated circuit chip 13 performs signal processing on the front surface, the back surface is not affected by signal processing. Therefore, the adhesion to the lead frame 11 may be a conductive adhesive 13b or an insulating adhesive such as an insulating adhesive 12b. Usually, a conductive adhesive 13b (such as an adhesive in which Ag powder is mixed with epoxy resin) having excellent workability and adhesive strength is used.

集積回路チップ１３の電極１３ｔとリードフレーム１１に配置された入出力端子としてのリード部１５とは、直径が数十μｍのワイヤ１４（例：Ａｕ線（金線））で接続されている。同様に、受光素子チップ１２とリード部１５、集積回路チップ１３と他のリード部１５、受光素子チップ１２と集積回路チップ１３が、ワイヤ１４で接続されている。   The electrode 13t of the integrated circuit chip 13 and the lead portion 15 as an input / output terminal disposed on the lead frame 11 are connected by a wire 14 (eg, Au wire (gold wire)) having a diameter of several tens of μm. Similarly, the light receiving element chip 12 and the lead portion 15, the integrated circuit chip 13 and the other lead portion 15, and the light receiving element chip 12 and the integrated circuit chip 13 are connected by a wire 14.

リードフレーム１１に搭載された受光素子チップ１２および集積回路チップ１３は、赤外線を透過し且つ可視光をカットする染料を混ぜた熱硬化性樹脂（封止樹脂）によって、樹脂封止され樹脂封止部１６を形成される。なお、樹脂封止部１６は、レンズ部１７を有する形態としてあるが、レンズ部１７を有しない形態とすることも可能である。   The light receiving element chip 12 and the integrated circuit chip 13 mounted on the lead frame 11 are resin-sealed with a thermosetting resin (sealing resin) mixed with a dye that transmits infrared light and cuts visible light. Part 16 is formed. In addition, although the resin sealing part 16 has a form having the lens part 17, a form without the lens part 17 is also possible.

樹脂封止後、樹脂封止部１６から露出しているリード部１５に対して、樹脂バリ取り、タイバーカット、リードカット、半田付け処理が施される。タイバーカットおよびリードカットによってリードフレーム１１のリード部１５が互いに分離されて、個々のリード部１５となる。   After resin sealing, resin deburring, tie bar cutting, lead cutting, and soldering are performed on the lead portion 15 exposed from the resin sealing portion 16. The lead portions 15 of the lead frame 11 are separated from each other by tie bar cutting and lead cutting, and become individual lead portions 15.

半田付けが施された樹脂封止型受光素子１０に対して、シールドケース３０によるケーシングが行われる。なお、シールドケース３０は、レンズ部１７の表面位置を覆って受光素子チップ１２に対向するように配置された十文字状の受光素子チップ対向部３１ｄを備える。   A casing by the shield case 30 is performed on the resin-sealed light receiving element 10 to which the soldering is applied. The shield case 30 includes a cross-shaped light receiving element chip facing portion 31d arranged so as to cover the surface position of the lens portion 17 and face the light receiving element chip 12.

本実施の形態では、第１嵌合部３３は、折り曲げられた舌片状の舌片端部３４を備え、第２嵌合部３６は、舌片端部３４が樹脂封止部１６の方から挿入された貫通穴３５ｈを有する枠状部３５を備える。   In the present embodiment, the first fitting portion 33 includes a bent tongue-like tongue piece end portion 34, and the second fitting portion 36 has the tongue piece end portion 34 inserted from the resin sealing portion 16. The frame-shaped part 35 which has the through-hole 35h made is provided.

この構成により、容易に形成することが可能な舌片端部３４および枠状部３５を適用して第１嵌合部３３と第２嵌合部３６との間の嵌合を容易に行わせることが可能となることから、生産性良く安価に製造することが可能な遠隔制御用受光装置１とすることができる。   With this configuration, the tongue piece end portion 34 and the frame-like portion 35 that can be easily formed are applied to facilitate the fitting between the first fitting portion 33 and the second fitting portion 36. Therefore, the remote control light-receiving device 1 that can be manufactured with high productivity and low cost can be obtained.

なお、舌片端部３４は、樹脂封止部１６の側面１６ｓに沿って側面対向部３１ｓより細く形成された側面対向延長部３２ｓの一部を樹脂封止部１６の厚さ方向に延長して形成されている。また、枠状部３５は、先端面対向延長部３２ｐの一部を延長方向と交差する方向に延長して形成され、先端面対向延長部３２ｐが樹脂封止部１６の裏面１６ｒに対向されたとき、舌片端部３４に対向するように予め折り曲げてある。   Note that the tongue piece end portion 34 is formed by extending a part of the side facing extension portion 32 s formed narrower than the side facing portion 31 s along the side surface 16 s of the resin sealing portion 16 in the thickness direction of the resin sealing portion 16. Is formed. Further, the frame-like portion 35 is formed by extending a part of the front end surface opposing extension portion 32p in a direction intersecting the extension direction, and the front end surface opposing extension portion 32p is opposed to the back surface 16r of the resin sealing portion 16. At this time, it is bent in advance so as to face the tongue end portion 34.

したがって、先端面対向延長部３２ｐを裏面１６ｒに対向させるように折り曲げることによって舌片端部３４を枠状部３５に対向させることが可能となる。つまり、舌片端部３４を枠状部３５に嵌合することによって、第１嵌合部３３（舌片端部３４）と第２嵌合部３６（枠状部３５）を容易かつ高精度に嵌合させることが可能となる。   Therefore, the tongue piece end portion 34 can be made to face the frame-like portion 35 by bending the tip surface facing extension portion 32p so as to face the back surface 16r. That is, by fitting the tongue piece end portion 34 to the frame-like portion 35, the first fitting portion 33 (tongue piece end portion 34) and the second fitting portion 36 (frame-like portion 35) are easily and accurately fitted. Can be combined.

すなわち、従来必要であった微小な爪部の折り曲げ作業、「かしめ」作業が不要となり、単に嵌め込む作業を行うだけで良いことから、組み立て作業工程を簡略化し、生産性を向上させることが可能となる。   In other words, it is not necessary to bend the small claws and “caulking” that were required in the past, and it is only necessary to perform the fitting operation, so the assembly process can be simplified and the productivity can be improved. It becomes.

舌片端部３４は、波状に折り曲げられている。したがって、舌片端部３４に弾力性を持たせることが可能となることから、舌片端部３４を枠状部３５へ容易に嵌合させることができる。   The tongue piece end 34 is bent into a wave shape. Accordingly, the tongue piece end portion 34 can be made elastic, so that the tongue piece end portion 34 can be easily fitted to the frame-like portion 35.

また、舌片端部３４は、側面対向部３１ｓの外側表面に対して外側へ突出させた外側突出部３４ｆを根元側に有し、外側突出部３４ｆは貫通穴３５ｈに嵌合させてある。したがって、第１嵌合部３３および第２嵌合部３６の間での嵌合強度を向上させることが可能となることから、第１嵌合部３３（舌片端部３４）と第２嵌合部３６（貫通穴３５ｈ）との嵌合を強固にして機械的に安定したシールドケース３０の取り付けが可能となり、信頼性の高い遠隔制御用受光装置１とすることができる。   Further, the tongue piece end portion 34 has an outer protruding portion 34f protruding outward with respect to the outer surface of the side facing portion 31s on the root side, and the outer protruding portion 34f is fitted in the through hole 35h. Therefore, since it becomes possible to improve the fitting strength between the 1st fitting part 33 and the 2nd fitting part 36, the 1st fitting part 33 (tongue piece edge part 34) and the 2nd fitting The fitting with the portion 36 (through hole 35h) is made strong and the mechanically stable shield case 30 can be attached, and the highly reliable remote control light receiving device 1 can be obtained.

また、舌片端部３４は、側面対向部３１ｓの内側表面に対して樹脂封止部１６の方へ突出させた内側突出部３４ｓを外側突出部３４ｆに隣接して有し、内側突出部３４ｓは樹脂封止部１６を挟む構成としてある。   Further, the tongue piece end portion 34 has an inner protruding portion 34s that protrudes toward the resin sealing portion 16 with respect to the inner surface of the side facing portion 31s adjacent to the outer protruding portion 34f, and the inner protruding portion 34s The resin sealing portion 16 is sandwiched.

この構成により、樹脂封止部１６を内側突出部３４ｓ（舌片端部３４）で挟み込むことが可能となることから、シールドケース３０を樹脂封止型受光素子１０に安定的に取り付けることが可能となり、信頼性の高い遠隔制御用受光装置１とすることができる。   With this configuration, the resin sealing portion 16 can be sandwiched between the inner projecting portions 34 s (tongue piece end portions 34), so that the shield case 30 can be stably attached to the resin-sealed light receiving element 10. The remote control light-receiving device 1 can be made highly reliable.

先端面対向延長部３２ｐは、先端面対向部３１ｐとの境界に折り曲げ用貫通穴４１を備える。したがって、先端面対向延長部３２ｐを先端面対向部３１ｐに対して容易かつ高精度に折り曲げることが可能となるので、先端面対向延長部３２ｐを容易かつ高精度に折り曲げて裏面１６ｒに対向させ、第１嵌合部３３および第２嵌合部３６相互間の嵌合を容易かつ高精度に実現することができる。   The tip surface opposing extension portion 32p includes a folding through hole 41 at the boundary with the tip surface opposing portion 31p. Therefore, the tip-face-facing extension 32p can be easily and highly accurately bent with respect to the tip-face-facing portion 31p. Therefore, the tip-face-facing extension 32p can be easily and highly accurately bent to face the back surface 16r. The fitting between the first fitting part 33 and the second fitting part 36 can be realized easily and with high accuracy.

また、先端面対向部３１ｐと先端面対向延長部３２ｐとの境界に折り曲げ用貫通穴４１の両端から延長させた折り曲げ溝４１ｇを設けることによってさらに容易かつ高精度に先端面対向延長部３２ｐを折り曲げることが可能となっている。   Further, by providing a bending groove 41g extended from both ends of the bending through hole 41 at the boundary between the tip surface facing portion 31p and the tip surface facing extension portion 32p, the tip surface facing extension portion 32p can be bent more easily and with high accuracy. It is possible.

先端面対向延長部３２ｐは、折り曲げ用貫通穴４１と同一形状の放熱用貫通穴４２を備える。したがって、放熱用貫通穴４２を容易に形成することが可能となり、また、樹脂封止型受光素子１０の裏面１６ｒからの放熱を効率的に行わせることが可能となることから、信頼性の高い遠隔制御用受光装置１を生産性良く安価に製造することができる。   The tip-face-facing extension 32p includes a heat dissipation through hole 42 having the same shape as the bending through hole 41. Therefore, the through-hole 42 for heat dissipation can be easily formed, and heat can be efficiently radiated from the back surface 16r of the resin-sealed light receiving element 10, so that the reliability is high. The remote control light-receiving device 1 can be manufactured at low cost with high productivity.

先端面対向延長部３２ｐは、裏面１６ｒの端部に対応させて屈曲され縁取りされた屈曲縁取り部（一般的にリブとも言われる）４３を備える。したがって、先端面対向延長部３２ｐの平面精度を向上させて樹脂封止部１６（裏面１６ｒ）に対する先端面対向延長部３２ｐの位置決めを高精度に行うことが可能となるので、シールドケース３０に対して樹脂封止部１６を高精度に位置決めされた遠隔制御用受光装置１を生産性良く安価に製造することができる。   The tip-surface-facing extension portion 32p includes a bent edge portion (generally referred to as a rib) 43 that is bent and edged corresponding to the end portion of the back surface 16r. Therefore, it is possible to improve the planar accuracy of the tip surface opposing extension portion 32p and position the tip surface opposing extension portion 32p with respect to the resin sealing portion 16 (back surface 16r) with high accuracy. Thus, the remote control light-receiving device 1 in which the resin sealing portion 16 is positioned with high accuracy can be manufactured with high productivity and at low cost.

屈曲縁取り部４３を備えることから、樹脂封止型受光素子１０がレンズ部１７を有しないレンズレスであっても、容易かつ高精度に樹脂封止型受光素子１０とシールドケース３０との位置決めを行うことが可能となる。   Since the bent edge portion 43 is provided, the resin-sealed light receiving element 10 and the shield case 30 can be easily and accurately positioned even if the resin-sealed light receiving element 10 is lensless without the lens portion 17. Can be done.

側面対向部３１ｓは、側面対向部３１ｓから延長されて側面１６ｓと交差する方向で裏面１６ｒの延長方向に突出されたケース耳部４４を備え、ケース耳部４４は対向する一対の側面１６ｓに対して先端面１６ｐからの位置を相互に異ならせてある。   The side facing portion 31s includes a case ear 44 that extends from the side facing portion 31s and protrudes in the extending direction of the back surface 16r in a direction intersecting the side 16s, and the case ear 44 is opposed to a pair of opposing side surfaces 16s. Thus, the positions from the tip surface 16p are different from each other.

したがって、樹脂封止型受光素子１０の製造工程で樹脂封止型受光素子１０を多連状に形成した状態の場合に、樹脂封止型受光素子１０の配置ピッチを最小してシールドケース３０を多連状に配置することが可能となるので、シールドケース３０と樹脂封止型受光素子１０との組み立てを多連状で生産性良く実行することができる。   Therefore, when the resin-sealed light-receiving elements 10 are formed in a multiple form in the manufacturing process of the resin-sealed light-receiving element 10, the shield case 30 is formed by minimizing the arrangement pitch of the resin-sealed light-receiving elements 10. Since it becomes possible to arrange in multiple rows, the assembly of the shield case 30 and the resin-encapsulated light receiving element 10 can be carried out in multiple rows with good productivity.

上述したとおり、遠隔制御用受光装置１は、樹脂封止型受光素子１０およびシールドケース３０を備えることから、電子機器（実施の形態４参照）に取り付けられ、送信機からの赤外線信号を受信して電子機器の動作を制御する制御信号を発生する。   As described above, since the remote control light receiving device 1 includes the resin-sealed light receiving element 10 and the shield case 30, it is attached to an electronic device (see Embodiment 4) and receives an infrared signal from a transmitter. A control signal for controlling the operation of the electronic device.

本実施の形態に係る遠隔制御用受光装置の基本的な構成は実施の形態１の遠隔制御用受光装置１と同様であるので、適宜実施の形態１を援用して主に異なる構成について説明する。   Since the basic configuration of the remote control light-receiving device according to the present embodiment is the same as that of the remote control light-receiving device 1 of the first embodiment, the different configurations will be mainly described with the appropriate use of the first embodiment. .

本実施の形態に係る遠隔制御用受光装置１（実施の形態２としての図示は省略）は、受光素子チップ１２を樹脂封止した樹脂封止部１６および樹脂封止部１６から導出されたリード部１５を有する樹脂封止型受光素子１０（図２Ａ、図２Ｂ参照）と、樹脂封止型受光素子１０を囲んで電磁シールドを行うシールドケース３０（図４Ａおよび図４Ｂ参照）とを備える。   The remote control light-receiving device 1 according to the present embodiment (illustration is omitted as the second embodiment) includes a resin-sealed portion 16 in which the light-receiving element chip 12 is sealed with resin and leads derived from the resin-sealed portion 16 A resin-sealed light receiving element 10 having a portion 15 (see FIGS. 2A and 2B) and a shield case 30 (see FIGS. 4A and 4B) that surrounds the resin-sealed light receiving element 10 and performs electromagnetic shielding.

Further, it is bent in advance so as to face the frame-shaped portion 37. Further, the frame-shaped part 37 is formed by removing a part of the side facing extension part 32 s in the thickness direction of the resin sealing part 16.

本実施の形態では、樹脂封止型受光素子１０を実装先の配線基板へ固定して保持するフック部４０を備え、フック部４０は、側面対向延長部３２ｓを第１嵌合部３３からさらに延長して形成されている。つまり、フック部４０は、シールドケース３０の一部を延長して形成してある。   In the present embodiment, a hook portion 40 is provided for fixing and holding the resin-sealed light receiving element 10 to a wiring board on which it is mounted. The hook portion 40 further includes a side-facing extension portion 32 s from the first fitting portion 33. It is formed to extend.

この構成により、フック部４０を有するディップ型の遠隔制御用受光装置１とすることが可能となり、樹脂封止型受光素子１０の位置決めおよび保持を第１嵌合部３３および第２嵌合部３６の間の嵌合で行うことが可能となるので、位置精度の高いディップ型の遠隔制御用受光装置１を生産性良く安価に製造することができる。   With this configuration, the dip-type remote control light-receiving device 1 having the hook portion 40 can be obtained, and positioning and holding of the resin-sealed light-receiving element 10 can be performed by the first fitting portion 33 and the second fitting portion 36. Therefore, the dip type remote control light-receiving device 1 with high positional accuracy can be manufactured with high productivity and at low cost.

舌片端部３８は、波状に折り曲げられている。したがって、舌片端部３８に弾力性を持たせることが可能となることから、舌片端部３８を枠状部３７へ容易に嵌合させることができる。   The tongue piece end portion 38 is bent in a wave shape. Therefore, the tongue piece end portion 38 can have elasticity, so that the tongue piece end portion 38 can be easily fitted to the frame-like portion 37.

また、舌片端部３８は、側面対向部３１ｓの外側表面に対して外側へ突出させた外側突出部３８ｆを根元側に有し、外側突出部３８ｆは貫通穴３７ｈに嵌合させる構造としてある。したがって、第１嵌合部３３および第２嵌合部３６の間での嵌合強度を向上させることが可能となることから、第１嵌合部３３（貫通穴３７ｈ）と第２嵌合部３６（舌片端部３８）との嵌合を強固にして機械的に安定したシールドケース３０の取り付けが可能となり、信頼性の高い遠隔制御用受光装置１とすることができる。   Further, the tongue piece end portion 38 has an outer protruding portion 38f that protrudes outward with respect to the outer surface of the side facing portion 31s on the root side, and the outer protruding portion 38f is configured to be fitted into the through hole 37h.

図５に基づいて、本実施の形態に係る遠隔制御用受光装置の貫通穴および舌片端部の関係を実施の形態３として説明する。なお、実施の形態１での貫通穴３５ｈおよび舌片端部３４に適用した場合について説明するが、実施の形態２の場合にも同様に適用できる。 <Embodiment 3>
Based on FIG. 5, the relationship between the through hole and the end of the tongue piece of the remote control light receiving device according to the present embodiment will be described as a third embodiment. In addition, although the case where it applies to the through-hole 35h and the tongue piece edge part 34 in Embodiment 1 is demonstrated, it can apply similarly to the case of Embodiment 2.

図５は、本発明の実施の形態３に係る遠隔制御用受光装置でのシールドケースの貫通穴および舌片端部の関係を示す平面図であり、（Ａ）は貫通穴の形状を直線状とした場合を示し、（Ｂ）は貫通穴の形状の一部を円弧状とした場合を示す。   FIG. 5 is a plan view showing the relationship between the through hole of the shield case and the end of the tongue piece in the remote control light receiving device according to Embodiment 3 of the present invention, and FIG. 5 (A) shows the shape of the through hole as a straight line. (B) shows a case where a part of the shape of the through hole is an arc shape.

同図（Ａ）では、貫通穴３５ｈの開口形状は、嵌合された外側突出部３４ｆに対応する側が直線状とされている。したがって、外側突出部は貫通穴に対して面接触で嵌合させることが可能となり、第１嵌合部３３と第２嵌合部３６との嵌合の強度を向上させることが可能となるので、シールドケース３０を樹脂封止型受光素子１０に強固に嵌合させ信頼性の高い遠隔制御用受光装置１とすることができる。   In FIG. 5A, the opening shape of the through hole 35h is linear on the side corresponding to the fitted outer protrusion 34f. Therefore, the outer protruding portion can be fitted to the through hole by surface contact, and the strength of fitting between the first fitting portion 33 and the second fitting portion 36 can be improved. Thus, the shield case 30 can be firmly fitted into the resin-sealed light receiving element 10 to provide a highly reliable remote control light receiving device 1.

同図（Ｂ）では、貫通穴３５ｈの開口形状は、嵌合された外側突出部３４ｆに対応する側が円弧状とされている。したがって、外側突出部３４ｆを貫通穴３５ｈに対して円弧上の２点での点接触で嵌合させることが可能となり、第１嵌合部３３と第２嵌合部３６との嵌合を容易に解除してシールドケース３０を容易に取り外すことが可能となるので、使い勝手の良い遠隔制御用受光装置１とすることができる。   In FIG. 5B, the opening shape of the through hole 35h is an arc shape on the side corresponding to the fitted outer protrusion 34f. Accordingly, the outer protrusion 34f can be fitted to the through hole 35h by point contact at two points on the arc, and the first fitting part 33 and the second fitting part 36 can be easily fitted. Therefore, the shield case 30 can be easily removed, so that the user-friendly remote control light-receiving device 1 can be obtained.
