〔発明の背景〕  [Background of the Invention]
携帯用電子器機の代表的なものとして携帯電話器がある。 携帯電話器は通信可 能ェリァであれば如何なる場所からも通話できるという大きな利点を持つている。 しかしその一方で、 電源に関する問題を抱えている。 携帯電話器は一定容量の電 池を備えているが、 携帯電話器が小型化する傾向にあることに伴って、 その電池 の容量も小さくなることを避けられない。 そのため使用しょうとする時にたまた ま電池が消耗しきって 、て通話を行なうことができないという現象が多くなる。 このことは携帯電話器の利便性を前提にして行動している場台に思わぬ不利益を 招きかねない。  A typical portable electronic device is a mobile phone.

Although mobile phones are equipped with batteries of a certain capacity, it is inevitable that the capacity of the batteries will be reduced as mobile phones tend to be smaller. As a result, when the battery is exhausted when trying to use it, the phenomenon of being unable to make a call increases. This can lead to unexpected disadvantages for those who operate with the convenience of mobile phones in mind.

〔発明を実施するための形態〕  [Mode for Carrying Out the Invention]
以下に本発明を実施形態に基づいて具体的に説明する。 図 1にその外観を示す ように、 一実施形態による小型偏平発電機は、 発電部を内蔵するケース 1の側面 に操作子として回転摘子 2を突出的に設けた構造を持つ。 そのケース 1は厚みが 例えば 1 c m程度の短円筒状である。  Hereinafter, the present invention will be specifically described based on embodiments. As shown in FIG. 1, the small flat power generator according to one embodiment has a structure in which a rotary knob 2 as an operator is protrudingly provided on a side surface of a case 1 having a built-in power generation unit. The case 1 has a short cylindrical shape with a thickness of, for example, about 1 cm.
ケース 1に内蔵の発電部は、 図 2に見られるように、 マグネット回転子 3と固 定電機子 4とからなる。 マグネッ ト回転子 3は、 偏平な有底円筒状に形成され、 その内周面に多数の磁極 3 pが設けられている。 多数の磁極 3 pは、 N磁極と S 磁極からなり、 これら両磁極が交互に並ぶようにされている。 このマグネッ ト回 転子 3は、 ケース 1に回 可能に支持させてある。 固定電機子 4は、 図 3に見ら れるように、 それぞれ電機子コィル 5力装着された磁極 4 pが一定のピッチで設 けられている。 この固定電機子 4は、 その磁極 4 pがマグネッ ト回転子 3の磁極 3 pと対向するようにマグネッ 卜回転子 3の内側に組み込まれている。 これらマ グネッ 卜回転子 3と固定電機子 4それぞれの磁極の関係は図 4の展開図に示すよ うになる。 磁極の数が多いので図 4にはその一部のみを示してある。 As shown in Fig. 2, the power generation section built in Case 1 is fixed to the magnet rotor 3 Consisting of 4 armatures. The magnet rotor 3 is formed in a flat bottomed cylindrical shape, and has a large number of magnetic poles 3 p on its inner peripheral surface. Many magnetic poles 3 p are composed of N magnetic poles and S magnetic poles, and these two magnetic poles are arranged alternately. The magnet rotator 3 is rotatably supported by the case 1. As shown in FIG. 3, the fixed armature 4 is provided with magnetic poles 4 p to which armature coils 5 are attached at a constant pitch. The fixed armature 4 is incorporated inside the magnet rotor 3 so that its magnetic pole 4 p faces the magnetic pole 3 p of the magnet rotor 3. The relationship between the magnetic poles of the magnet rotor 3 and the fixed armature 4 is as shown in the developed view of FIG. Due to the large number of magnetic poles, only a part is shown in FIG.
回転摘子 2は、 図 2に見られるように、 閉鎖円筒伏に形成され、 軸 7により回 転可能に支持されている。 その軸 7は、 それ自体がケース 1に回転可能に支持さ れている。 回転摘子 2と铀了の間にはぜんまい 8が介在している。 すなわちぜん まい 8は、 軸 7に一端を固定されるとともに他端を回転摘子 2に固定されており、 回転摘子 2に手動で加えられる回転力をその巻き上がりにより蓄積しつつギア群 9を介してマグネッ ト回転子 3に伝える。 ギア群 9は、 軸 7に固定の大ギア 1 1、 ケース 1に回転可能に支持されるとともに大ギア 1 1に嚙合する小ギア 1 2、 こ の小ギア 1 2に嚙合する大ギア 1 3、 及びマグネッ ト回耘子 3に固定されるとと もに小ギア 1 2に嚙合する小ギア 1 4からなり、 この例では 2 0 ~ 3 0倍程度の 增速率を与える。  As shown in FIG. 2, the rotary knob 2 is formed in a closed cylindrical shape, and is rotatably supported by a shaft 7. The shaft 7 itself is rotatably supported by the case 1. A spring 8 is interposed between the rotary knob 2 and the end. In other words, the mainspring 8 has one end fixed to the shaft 7 and the other end fixed to the rotary knob 2. To the magnet rotator 3 via. The gear group 9 includes a large gear 11 fixed to the shaft 7, a small gear 12 supported rotatably on the case 1 and mating with the large gear 11, and a large gear 13 mating with the small gear 12. , And a small gear 14 fixed to the magnet stub 3 and combined with the small gear 12.

図 5に見られるように、 回転摘子 2の外周には一方向回転手段 1 5が設けられ ている。 この一方向回転手段 1 5は、 回転摘子 2の外周に設けられたラチヱッ ト 歯 1 6と、 これに歯合するラチヱッ ト爪を有するラチヱッ 卜レバー 1 7からなる。 ラチヱッ 卜レバ一 1 7は、 ケース 1に揺動可能に取り付けてある。 またラチエツ トレバー 1 7は、 図示せぬばねなどにより回転摘子 2に押接する方向に付勢して ある。  As shown in FIG. 5, a one-way rotating means 15 is provided on the outer periphery of the rotary knob 2. The one-way rotating means 15 includes a ratchet tooth 16 provided on the outer periphery of the rotary knob 2 and a ratchet lever 17 having a ratchet claw meshing therewith. The ratchet lever 17 is swingably attached to the case 1. The ratchet lever 17 is urged by a spring (not shown) in a direction in which the ratchet lever 17 presses against the rotary knob 2.
したがって回転摘子 2を手の指で操作して回転させると、 ぜんまい 8とギア群 9を介してマグネッ ト回転子 3が高速回転する。 この結果、 固定電機子 4の各電 機子コイル 5に起電力が発生し、 図 4における電機子コイル 5の端子 T a、 T b から電力を取り出すことができる。 実験によると、 5ボルト 8 0ミ リアンペアの 出力電圧を得ることができ、 巻き上げたぜんまいのエネルギ一が開放される約 3 0秒の間この出力電圧を継続して得られた。 Therefore, when the rotary knob 2 is operated and rotated with the finger of the hand, the magnetic rotor 3 rotates at high speed via the mainspring 8 and the gear group 9. As a result, an electromotive force is generated in each of the armature coils 5 of the fixed armature 4, and power can be extracted from the terminals Ta and Tb of the armature coil 5 in FIG. Experiments show that 5 volts of 80 ma An output voltage was obtained, and this output voltage was continuously obtained for about 30 seconds when the energy of the wound-up spring was released.
このような小型偏平発電機は、 固定電機子 4の磁極 4 pの幅をマグネッ卜回転 子 3の磁極 3 pの幅と等しくする場合に最も効率的な発電が可能である。 また本 発明による小型偏平発電機は、 固定電機子 4が多数の磁極を有することに一つの 特徴があるが、 このことにより実質的に直流的な発電が可能であり、 得られる電 力をコンデンサなどを介することなく直接に携帯電話器などに供給することを可 能とする。  Such a small flat power generator can generate power most efficiently when the width of the magnetic pole 4 p of the fixed armature 4 is made equal to the width of the magnetic pole 3 p of the magnet rotor 3. The small flat generator according to the present invention has one feature in that the fixed armature 4 has a large number of magnetic poles. It is possible to supply the data directly to mobile phones, etc., without going through any other means.

That is, the output from the small flat generator D is supplied to the mobile phone circuit H via the battery B.
以上の実施形態では、 駆動力蓄積手段にぜんまいを用いていたが、 この他のも のを用いることも可能である。 また駆動力蓄積手段は必ずしも必要でなく、 操作 子に加えられる駆動力をマグネッ卜回転子に直接的に伝えるようにすることもで きる。 また以上の実施形態では、 操作子を回転摘子の形態にしてある力 この他 に例えば揺動構造などとすることも可能である。 さらに操作子を設ける位置も上 記形態に限られず自由に選択することができる。  In the above embodiment, the mainspring is used as the driving force accumulating means. However, other means can be used. Further, the driving force accumulating means is not always necessary, and the driving force applied to the operation element can be directly transmitted to the magnet rotor. Further, in the above embodiment, the operating element is in the form of a rotary knob, and in addition to this force, for example, a swinging structure can be used.
