Description

本発明は、電球や発光ダイオードを発光させるための、あるいは音響装置の音を発生させるための、あるいは動物等の形態を動作させる動作装置を動作させるための電源となる発電装置を内蔵した筆記具に関するものである。   The present invention relates to a writing instrument having a built-in power generation device serving as a power source for causing a light bulb or a light emitting diode to emit light, generating sound of an acoustic device, or operating an operating device such as an animal. Is.

従来、発光ダイオードや電球を具備した照明付の筆記具が多数提案されている。また、音響装置を有し音響効果や、動物等の形態を付設し前記形態を動かす動作効果が得られる機能を付加したものも提案され販売もされている。しかし、前記した機能を作用させるための電源は、ほとんどのものが電池である。   Conventionally, many writing instruments with illumination equipped with light emitting diodes and light bulbs have been proposed. In addition, an audio device having a sound device and a function to which a sound effect and an operation effect of moving the shape by attaching a form such as an animal are proposed and sold. However, most of the power sources for performing the above-described functions are batteries.

しかし、こうした電源を電池とするものでは、電池がなくなると交換しなければならないが、普段予備電池を持ち歩く事はなく、電池が消耗してしまうと（切れてしまうと）、前記した機能を使用することはできないという問題があった。   However, if the power source is a battery, it must be replaced when the battery runs out, but usually the spare battery is not carried around, and when the battery is exhausted (it runs out), the above function is used. There was a problem that you can't.

本発明者はこうした問題を解決するために、電源として電池交換が不要な発電装置を内蔵した筆記具を得ることを考えた。従来、シャープペンシルにおいて、芯を繰り出す構造として軸筒内に重量体を設け、シャープペンシルを振ることで重量体の慣性力により芯タンクが前進し、芯を保持するチャックを開閉する構造に係る考案が、実開昭５４−６１４３号公報や実開平４−２０４９０号公報により提案され、実際に商品化もされており、その構造については良く知られている。本発明者は、こうした筆記具に着目し、筆記具を振ることにより発電可能な発電装置を得ることで前記した問題を解決することを試みた。   In order to solve such problems, the present inventor considered obtaining a writing instrument incorporating a power generation device that does not require battery replacement as a power source. Conventionally, in a mechanical pencil, a weight body is provided in the shaft cylinder as a structure for feeding out the core, and the mechanical tank is moved forward by the inertial force of the weight body by shaking the mechanical pencil to open and close the chuck that holds the core. However, it has been proposed by Japanese Utility Model Laid-Open No. 54-6143 and Japanese Utility Model Laid-Open No. 4-20490 and is actually commercialized, and its structure is well known. The inventor paid attention to such a writing instrument, and tried to solve the above-described problem by obtaining a power generation device capable of generating power by shaking the writing instrument.

従来、筆記具を振ることにより発電可能な発電装置を内蔵した筆記具として、特開平１−２１８８９９号公報により「発電装置内蔵筆記用具」が、また本出願人の先の出願である特開平８−９０９８６号公報により「筆記具」が提案されている。前者の発明は、筆記用具を使用する際の振動で発電し、筆記用具に具備された電気装置に電気を供給することができ、振動によって電気エネルギーを発生する発電機をボールペンの頭部に内蔵したものである。後者の発明は、圧電素子を用いて、移動部材の移動により圧電素子に変位を与えて電圧を得、その電圧を電気装置に供給するものである。   Conventionally, as a writing instrument with a built-in power generation device capable of generating power by shaking a writing instrument, Japanese Patent Laid-Open No. 1-218899 discloses “a writing instrument with built-in power generation device” and Japanese Patent Application Laid-Open No. 8-90986, which is an earlier application of the present applicant. “Writing tools” is proposed in the Gazette. The former invention generates electricity by vibration when using a writing instrument, can supply electricity to the electrical device provided in the writing instrument, and a generator that generates electrical energy by vibration is built in the head of the ballpoint pen It is a thing. The latter invention uses a piezoelectric element to obtain a voltage by applying displacement to the piezoelectric element by the movement of a moving member, and supplies the voltage to an electric device.

しかし、前者においては、発電機についての具体的な記載はない。後者においては、圧電素子を用いるために、発電効果を得るには圧電素子を振動させる必要があり、そのために圧電素子に接触子を設け、移動部材の移動により接触子を振動させる構造としなければならなく、構造も煩雑となる。
実開昭５４−６１４３号号公報 実開平４−２０４９０号公報 特開平１−２１８８９９号公報 特開平８−９０９８６号公報 However, there is no specific description about the generator in the former. In the latter, since a piezoelectric element is used, it is necessary to vibrate the piezoelectric element in order to obtain a power generation effect. For this purpose, a contact is provided on the piezoelectric element, and the contact is vibrated by movement of the moving member. In addition, the structure becomes complicated.

本発明においては、軸筒内に、コイルを固定し磁石を移動可能に配設しても良いし、または、磁石を固定しコイルを移動可能に配設しても良い。また、磁石は、棒形状或いは円筒形状でも良く、特に特定されるものではない。磁石が円筒形状の場合には、コイルは磁石の外側或いは内側のどちらの位置に配設しても良く、コイルが磁石の磁界中を磁束を切って移動することで、または磁石がコイルを貫く磁束を変化するように移動することで発生する起電力が効率良く発生すれば良いのであって、コイルや磁石の配設状態は適宜検討して決めれば良い。また、コイルや磁石の数についても、特に制約があるものではない。   In the present invention, the coil may be fixed and the magnet may be movably disposed in the shaft tube, or the magnet may be fixed and the coil may be movably disposed. Further, the magnet may be rod-shaped or cylindrical, and is not particularly specified. When the magnet has a cylindrical shape, the coil may be disposed either on the outside or inside of the magnet, and the coil moves through the magnetic field of the magnet while cutting the magnetic flux, or the magnet penetrates the coil. The electromotive force generated by moving so as to change the magnetic flux may be generated efficiently, and the arrangement state of the coils and magnets may be determined by appropriate examination. Further, the number of coils and magnets is not particularly limited.

本発明の発電装置を内蔵した筆記具は、発電装置として、コイルが磁石の磁界中を磁束を切って移動することでまたは磁石がコイルを貫く磁束を変化するように移動することで起電力を発生させるもので、従来より良く知られている原理を用いたものである。軸筒を振る等して軸筒内の磁石やコイルを移動させるだけで、電球や発光ダイオードを発光させるための、あるいは音響装置の音を発生させるための、あるいは動物等の形態を動作させる動作装置を動作させるための起電力を発生し、電池を使用することなく前記のような機能を作用させることができた。また、電池を使用していないので電池交換の煩わしさがなく、前記した機能を使用したいときに何時でも使用することができるという利点がある。   The writing instrument incorporating the power generation device of the present invention generates an electromotive force as a power generation device by moving the coil in a magnetic field of the magnet while cutting the magnetic flux or by moving the magnet to change the magnetic flux passing through the coil. This is a principle that is well known in the art.

Further, since no battery is used, there is no need to replace the battery, and there is an advantage that it can be used anytime when the above-described function is desired.

本発明における磁石は、一般的なもので良いが、高い発電効率を得るためにはより高磁性を持つサマコバ磁石を使用することが望ましい。電源回路部としては、一般的に知られているダイオードからなる整流回路とコンデンサで構成され、過電圧で動作装置が誤動作または破壊されることを防ぐために、定電圧ダイオードやチョークコイルで構成されるサージ吸収回路や、発光ダイオード等を安定して発光させるために、電圧を安定させるための安定化回路を設けた方が良い。   The magnet in the present invention may be a general one, but it is desirable to use a Somakoba magnet having higher magnetism in order to obtain high power generation efficiency. The power supply circuit section is composed of a rectifier circuit and a capacitor, which are generally known diodes, and a surge composed of a constant voltage diode or choke coil to prevent the operating device from malfunctioning or being destroyed by overvoltage. In order to make the absorption circuit and the light emitting diode emit light stably, it is better to provide a stabilization circuit for stabilizing the voltage.

本発明の実施例を図面を用いて説明する。便宜上、発光ダイオードを具備した照明付筆記具として説明するが、これに限定されるものではない。同じ部材、同じ箇所を示すものには同じ符号を付してある。
図１に示す第１の実施例は、ボールペン１の場合である。軸筒２内には、インキ（図示せず）が充填され、先端にボールペンチップ３を具備したレフィル４が収容してある。軸筒２の先端には口金部材５が、後端には尾栓６が装着してあり、前記レフィル４の後端を尾栓６に形成した保持孔６ａに挿着して保持している。ボールペンチップ３の先端は、口金部材５の先端開口部５ａより常時突出したものとしてある。 Embodiments of the present invention will be described with reference to the drawings. For convenience, it will be described as a writing instrument with a light emitting diode, but the present invention is not limited to this. The same code | symbol is attached | subjected to what shows the same member and the same location.
The first embodiment shown in FIG. 1 is a case of a ballpoint pen 1. The shaft cylinder 2 is filled with ink (not shown), and a refill 4 having a ballpoint pen tip 3 at the tip is accommodated. A cap member 5 is attached to the front end of the shaft tube 2, and a tail plug 6 is attached to the rear end, and the rear end of the refill 4 is inserted and held in a holding hole 6 a formed in the tail plug 6. . The tip of the ball-point pen tip 3 is assumed to always protrude from the tip opening 5 a of the base member 5.

口金部材５は、軸筒２内に挿入し後方に延びた円筒部７を有している。該円筒部７の後端には閉塞部材８を螺着してあり、円筒部７の前方段部９と円筒部７の開口した後端と閉塞部材８で形成された後方段部１０とで空間部１１を形成してある。レフィル４の外側に、レフィル４に沿って長手方向に移動可能に円筒状に形成した磁石１２を遊嵌して、空間部１１内に配設してある。前記前方段部９と後方段部１０には、磁石１２の移動による衝撃を和らげるためにリング状でゴム製の弾性体１３を付設してある。前記空間部１１に対向する円筒部７の外周面には、凹溝１４を形成してあり、そこに導線を巻いたコイル１５を設けてある。   The base member 5 has a cylindrical portion 7 that is inserted into the shaft tube 2 and extends rearward. A closing member 8 is screwed to the rear end of the cylindrical portion 7, and includes a front step portion 9 of the cylindrical portion 7, an open rear end of the cylindrical portion 7, and a rear step portion 10 formed by the closing member 8. A space 11 is formed. A magnet 12 formed in a cylindrical shape so as to be movable in the longitudinal direction along the refill 4 is loosely fitted on the outside of the refill 4 and disposed in the space portion 11. The front step portion 9 and the rear step portion 10 are provided with a ring-shaped rubber elastic body 13 in order to reduce the impact caused by the movement of the magnet 12. A concave groove 14 is formed on the outer peripheral surface of the cylindrical portion 7 facing the space portion 11, and a coil 15 around which a conductive wire is wound is provided.

前記閉塞部材８の後方の軸筒２内部には、図２に示すような、一般的に知られている整流回路１６、サージ吸収回路１７、コンデンサ１８、安定回路１９、及びスイッチ２０からなる電源回路部２１を有する基板２２を配設してある。電源回路２１は、コイル１５の両端の導線２３、２４を、先ず、整流回路１６に接続し、次に該整流回路１６からサージ吸収回路１７、コンデンサ１８に順次接続され、コンデンサ１８から出力された導線２３、２４は、一方の導線２３にスイッチ２０を設けて、安定回路１９に接続した構成としてある。   As shown in FIG. 2, a power source comprising a generally known rectifier circuit 16, surge absorbing circuit 17, capacitor 18, stabilizing circuit 19, and switch 20 is disposed inside the shaft cylinder 2 behind the closing member 8. A substrate 22 having a circuit portion 21 is disposed. In the power supply circuit 21, the conductive wires 23 and 24 at both ends of the coil 15 are first connected to the rectifier circuit 16, and then sequentially connected from the rectifier circuit 16 to the surge absorbing circuit 17 and the capacitor 18 and output from the capacitor 18. The conducting wires 23 and 24 are configured such that one of the conducting wires 23 is provided with a switch 20 and connected to the stabilization circuit 19.

軸筒２の後端に装着した尾栓６には、保持孔２５を形成して該保持孔２５に保持部材２６により発光ダイオード２７を装着してある。該発光ダイオード２７には、前記安定回路１９から出た導線２８、２９が接続してある。   A holding hole 25 is formed in the tail plug 6 attached to the rear end of the shaft tube 2, and a light emitting diode 27 is attached to the holding hole 25 by a holding member 26. The light emitting diode 27 is connected to conductive wires 28 and 29 from the ballast circuit 19.

従って、軸筒２を振ることにより電源回路部２１のコンデンサ１８に電流が蓄えられ、スイッチを入れることにより、発光ダイオード２７を発光させることができる。電流の蓄えが無くなったら、再度、軸筒２を振ることにより電源回路部２１に電流を蓄えることができ、何時でも発光ダイオード２７を発光させることができる。   Therefore, a current is stored in the capacitor 18 of the power supply circuit unit 21 by shaking the shaft cylinder 2, and the light emitting diode 27 can be caused to emit light by turning on the switch. When the current is no longer stored, the current can be stored in the power supply circuit unit 21 by shaking the shaft cylinder 2 again, and the light emitting diode 27 can be caused to emit light at any time.

図３に示す第２の実施例は、シャープペンシル５１の場合である。軸筒５２には口金部材５３が連結してある。鉛芯を繰り出す構造は従来より良く知られている構造で、口金部材５３及び軸筒５２の内部に、外周に締めリング５４を遊嵌したチャック５５を連結部材５６を介して先端に連結した芯タンク５７を配設してある。口金部材５３の内壁の段部５８に配設したワッシャー５９に前記締めリング５４が当接可能としてある。前記ワッシャー５９と連結部材５６の先端との間にコイルスプリング６０を張架して、前記チャック５５を長手方向後方に付勢してある。これにより、通常時は締めリング５４がワッシャー５９に当接してチャック５５を締め付け、チャック５５は閉じられる。芯タンク５７を前進させることによりチャック５５も前進し、締めリング５４も若干前進するが、締めリング５４は口金部材５３の内壁に形成した小径段部６１に当接することにより前進を妨げられ、チャック５５のみが前進し、締めリング５４の締め付けから解放されチャック５５は開く。   The second embodiment shown in FIG. 3 is the case of the mechanical pencil 51. A base member 53 is connected to the shaft tube 52. The lead feed-out structure is a well-known structure, and is a core in which a chuck 55 in which a fastening ring 54 is loosely fitted on the outer periphery is connected to the tip via a connecting member 56 inside the base member 53 and the shaft tube 52. A tank 57 is provided. The fastening ring 54 can be brought into contact with a washer 59 disposed on a step 58 on the inner wall of the base member 53. A coil spring 60 is stretched between the washer 59 and the tip of the connecting member 56 to urge the chuck 55 backward in the longitudinal direction. Thereby, normally, the fastening ring 54 contacts the washer 59 to fasten the chuck 55, and the chuck 55 is closed. When the lead tank 57 is moved forward, the chuck 55 is also moved forward, and the fastening ring 54 is also moved forward slightly. However, the fastening ring 54 is prevented from moving forward by coming into contact with a small-diameter step portion 61 formed on the inner wall of the base member 53. Only 55 moves forward and is released from tightening of the tightening ring 54 and the chuck 55 is opened.

前記実施例と同様に、口金部材５３は、軸筒５２内に挿入し後方に延びた円筒部６２を有している。該円筒部６２の後端には、芯タンク５７を通す孔６３を有した隔壁部６４を設けた中継パイプ６５が螺着してある。芯タンク５７の外側には該芯タンク５７に沿って長手方向に移動可能に円筒状に形成した磁石６６を、前記鍔部材に衝接可能に遊嵌して配設してある。円筒部６２の後端は、中継パイプ６５の隔壁部６４で閉塞されており、そこに磁石６６の移動による衝撃を和らげるためにリング状でゴム製の弾性体６７を付設してある。円筒部６２の磁石６６が移動可能な範囲の外周面には、凹溝６８を形成してあり、そこに導線を巻いたコイル６９を設けてある。   As in the previous embodiment, the base member 53 has a cylindrical portion 62 inserted into the shaft tube 52 and extending rearward. A relay pipe 65 provided with a partition wall 64 having a hole 63 through which the core tank 57 passes is screwed to the rear end of the cylindrical part 62. On the outside of the lead tank 57, a magnet 66 formed in a cylindrical shape so as to be movable in the longitudinal direction along the lead tank 57 is loosely fitted to the flange member so as to be brought into contact therewith. The rear end of the cylindrical portion 62 is closed by a partition wall portion 64 of the relay pipe 65, and a ring-shaped rubber elastic body 67 is attached thereto in order to reduce the impact caused by the movement of the magnet 66. A concave groove 68 is formed on the outer peripheral surface of the cylindrical portion 62 in a range where the magnet 66 can move, and a coil 69 wound with a conductive wire is provided there.

芯タンク５７の後端には、中継パイプ６５内を移動可能に形成した円筒状のノック体７０が遊嵌して配設してある。中継パイプ６５の後部には、図４に示すように、長手方向に延びた摺動溝７１と該摺動溝７１の前端より周方向後方に傾斜した係止溝７２が形成してあり、ノック体７０の前端部７０ａにコ字型に切欠きを設けて内方に撓み可能とした側片（図示せず）に、前記摺動溝７１及び係止溝７２を摺動可能な係止突起７３を設けて、該係止突起７３を前記摺動溝７１に係止してある。   At the rear end of the lead tank 57, a cylindrical knock body 70 formed to be movable in the relay pipe 65 is loosely fitted. As shown in FIG. 4, a sliding groove 71 extending in the longitudinal direction and a locking groove 72 inclined rearward in the circumferential direction from the front end of the sliding groove 71 are formed at the rear portion of the relay pipe 65. A locking protrusion capable of sliding the sliding groove 71 and the locking groove 72 on a side piece (not shown) provided with a U-shaped notch in the front end portion 70a of the body 70 so as to be bent inward. 73 is provided, and the locking projection 73 is locked to the sliding groove 71.

通常の筆記状態では、中継パイプ６５の隔壁部６４とノック体７０の前端部７０ａに形成した外鍔部７４との間にリターンスプリング７５が張架され、係止突起７３は摺動溝７１後端に偏倚している。従って、ノック体７０の芯タンク５７より後方に形成した内鍔部７６は芯タンク５７の後端より適宜離間するようにしてある。また、ノック体７０の後部には尾栓７７を挿着してあり、該尾栓７７には、保持孔７８を形成して該保持孔７８に、前記実施例と同様の発光ダイオード２７を装着してある。   In a normal writing state, a return spring 75 is stretched between the partition wall portion 64 of the relay pipe 65 and the outer flange portion 74 formed at the front end portion 70 a of the knock body 70, and the locking projection 73 is located after the sliding groove 71. It is biased to the end. Therefore, the inner collar portion 76 formed rearward of the core tank 57 of the knock body 70 is appropriately separated from the rear end of the core tank 57. Further, a tail plug 77 is inserted in the rear part of the knock body 70. A holding hole 78 is formed in the tail plug 77, and the same light emitting diode 27 as that of the above embodiment is mounted in the holding hole 78. It is.

前記中継パイプ６５より後方の軸筒５２内部には、前記実施例と同様の電源回路部２１有した基板２２を配設してあり、コイル６９の両端の導線７９、８０が接続し、前記電源回路部２１から出た導線７９、８０は発光ダイオード２７に接続してある。   Inside the shaft cylinder 52 behind the relay pipe 65, a substrate 22 having a power supply circuit portion 21 similar to that of the above-described embodiment is disposed, and conductive wires 79 and 80 at both ends of the coil 69 are connected to the power supply. Conductive wires 79 and 80 extending from the circuit unit 21 are connected to the light emitting diode 27.

本実施例のシャープペンシルは、通常の筆記状態では、軸筒５２を振ることにより生じる磁石６６の慣性力により芯タンク５７及びチャック５５を前進させて鉛芯８１を繰り出すころができる。また、携帯する場合には、尾栓７７を押圧して前進させ、チャック５５を拡開した後に、尾栓７７を回転してノック体７０を回転させ、係止突起７３を軸筒５２の係止溝７２に嵌め込む。こうした状態では、磁石６６が摺動してもチャック５５が拡開しているために、鉛芯８１の繰り出しは行われない。そして、筆記状態に戻すためには、単に尾栓７７を押圧すれば、係止突起７３が係止溝７２に沿って前進し、係止溝７２より外れて摺動溝７１内に位置される。   In the normal writing state, the mechanical pencil according to the present embodiment can advance the lead tank 81 and the lead lead 81 by advancing the lead tank 57 and the chuck 55 by the inertia force of the magnet 66 generated by shaking the shaft cylinder 52. In the case of carrying, the tail plug 77 is pushed and moved forward, the chuck 55 is expanded, the tail plug 77 is rotated and the knock body 70 is rotated, and the locking protrusion 73 is engaged with the shaft cylinder 52. Fit into the stop groove 72. In such a state, even if the magnet 66 slides, the lead 55 is not extended because the chuck 55 is expanded. In order to return to the writing state, simply press the tail plug 77, the locking projection 73 advances along the locking groove 72, disengages from the locking groove 72, and is positioned in the sliding groove 71. .

従って、本実施例のシャープペンシルでは、軸筒５２を振ってり芯を繰り出す度に電源回路部２１に電流が蓄えられ、前記実施例の場合と同様に、スイッチを入れることにより、発光ダイオード２７を発光させることができる。電流の蓄えが無くなったら、再度、軸筒２を振ることにより電源回路部２１に電流を蓄えることができ、何時でも発光ダイオード２７を発光させることができる。   Therefore, in the mechanical pencil of this embodiment, current is stored in the power supply circuit unit 21 every time the shaft cylinder 52 is swung and the lead is drawn out, and the light emitting diode 27 is turned on by turning on the switch as in the case of the above embodiment.
