Description

本考案は自動紙送り器の構造に関し、特にプリンター、スキャナー、コピー機及びファックスなどのオフィス設備に使用される自動紙送り器給紙感知機構に関する。   The present invention relates to a structure of an automatic paper feeder, and more particularly to an automatic paper feeder paper feed sensing mechanism used in office equipment such as a printer, a scanner, a copier, and a fax machine.

図1〜図3が示すように、従来の自動紙送り器は紙を取る場所に紙表面の質量を感知する紙質量感応器150’を設置する。該紙質量感応器150’は紙の光に対する反射の強さを利用し、紙1’の表面の粗さなどを判断することで、コピー機、ファックスなどのオフィス設備が紙に対する処理効果をアップする。自動取紙器は更に紙1’がオフィス設備の給紙感知器に進入したか否かを感知する。該給紙感知器は台座110’及び支え120’を含む。支え120’の上に紙送り感応器180’を設け、該紙送り感応器180’と信号処理機(図に未掲載)は互いに接続する。支え120’の上に揺動台170’を設け、アーム台170’に動力アーム171’及び揺動アーム172’を具有する。支えスタンド120'と揺動台170’の間に、揺動台170’がバランスを保つためのねじりばね190’を設置し、揺動台170’自身の重さとねじりばね190’のひねる力でバランスが保たれる。紙1’が進入する際、揺動台170’の動力アーム171’を押し、動力アーム171’は揺動アーム172’を動かす。紙送り感応器180’は揺動アーム172’の位置の変化を感知し、電気信号を信号処理機に発する。信号処理機は紙1’がオフィス設備に進入したか否かを判断する。   As shown in FIGS. 1 to 3, a conventional automatic paper feeder is provided with a paper mass sensor 150 'that senses the mass of the paper surface at a place where the paper is taken. The paper mass sensor 150 'uses the intensity of reflection of light on the paper to determine the surface roughness of the paper 1', etc., and office equipment such as copiers and fax machines improves the processing effect on the paper. To do. The automatic paper picker further senses whether the paper 1 'has entered the paper feed detector of the office facility. The paper feed sensor includes a pedestal 110 'and a support 120'. A paper feed sensor 180 'is provided on the support 120', and the paper feed sensor 180 'and a signal processor (not shown) are connected to each other. A swing base 170 'is provided on the support 120', and the arm base 170 'has a power arm 171' and a swing arm 172 '. A torsion spring 190 'is installed between the support stand 120' and the swinging base 170 'to maintain the balance of the swinging base 170', and the weight of the swinging base 170 'itself and the twisting force of the torsion spring 190' Balance is maintained. When the paper 1 'enters, the power arm 171' of the swing base 170 'is pushed, and the power arm 171' moves the swing arm 172 '. The paper feed sensor 180 'senses a change in the position of the swing arm 172' and issues an electrical signal to the signal processor. The signal processor determines whether the paper 1 'has entered the office facility.

従来の自動紙送り器は紙の表面質量を感知する紙質量感応器150’と、紙がオフィス設備内に進入したか否かを感知する給紙感知器を別々に設置しているため、自動紙送り器の部品は多い上に複雑な構造となり、製造が困難且つコストが高い。また、アーム台170’はねじりばね190’のひねる力を頼りに自分自身の重さとバランスを保つため、外部よりの震動により、揺動台170’の揺動アーム172’が動きやすく、給紙感知器が自動紙送り器に紙が入ったと誤認することもあり、自動紙送り器など全てのオフィス設備の誤作動を招く。また、揺動台170’の動力アーム171’及び揺動アーム172’の動くスペースを残す必要があるため、台座110’の上に動力アーム171’が動くための溝111’を設置するため、台座110’の構造も複雑となり、改善する必要があった。
特開２００５−４１６９７号公報 The conventional automatic paper feeder has a paper mass sensor 150 'that senses the surface mass of the paper and a paper feed sensor that senses whether the paper has entered the office equipment. The paper feeder has many parts and a complicated structure, making it difficult and expensive to manufacture. Also, the arm base 170 'relies on the twisting force of the torsion spring 190' to maintain its own weight and balance, so that the swing arm 172 'of the swing base 170' is easy to move due to external vibration, and the paper feed The sensor may mistakenly recognize that paper has entered the automatic paper feeder, leading to a malfunction of all office equipment such as the automatic paper feeder. Further, since it is necessary to leave a space for moving the power arm 171 ′ and the swing arm 172 ′ of the swing base 170 ′, in order to install the groove 111 ′ for the power arm 171 ′ to move on the base 110 ′, The structure of the pedestal 110 ′ is also complicated and needs to be improved.

前記従来構造の欠点を解決するために、必要とする部品を少なくし、構造が簡単且つ、製造コストを下げ、作動が正確及び誤作動を避けることのできる自動紙送り器給紙感知機構を提供することを主な課題とする。   In order to solve the drawbacks of the conventional structure, an automatic paper feeder feed sensing mechanism is provided that requires fewer parts, has a simple structure, reduces manufacturing costs, and operates accurately and avoids malfunction. The main issue is to do.

前記課題を達成するために、本考案の自動紙送り器給紙感知機構に含まれるのは本体であり、本体に取紙ルートを具有する。信号発生器アセンブリーを本体に設置する。信号発生器アセンブリーは固定台を含み、固定台の上に給紙感応器を設け、給紙感応器を取紙ルートの上に設置する。 In order to achieve the above object, the automatic paper feeder paper feed sensing mechanism of the present invention includes a main body, and the main body has a paper feeding route. Install the signal generator assembly on the body. The signal generator assembly includes a fixed base, a paper feed sensor is provided on the fixed base, and the paper feed sensor is installed on the paper route.

本考案の自動紙送り器給紙感知機構の、固定台の上に設置する給紙感応器が従来技術の別々に設置する紙質量感応器と給紙感知器の代わりであり、固定台はアーム台の代わりとすることで、構造をシンプルにし、製造コストを低くする。給紙感応器が紙の進入を感知するとき、紙と取紙ルートの背景区域の違いにより判断を行う。従来技術のようにムーブアームの動きに頼るのではないため、誤作動がなくなる。   In the automatic paper feeder paper feed sensing mechanism of the present invention, the paper feed sensor installed on the fixed base is an alternative to the conventional paper mass sensor and paper feed sensor installed separately, and the fixed base is an arm. By replacing the stand, the structure is simplified and the manufacturing cost is reduced. When the paper feed sensor senses the entry of paper, it makes a judgment based on the difference between the background area of the paper and the paper taking route. Since it does not rely on the movement of the move arm as in the prior art, malfunctions are eliminated.

従来技術の別々に設置するペーパー質量感応器と給紙感知器の代わりに、固定台の上に給紙感応器を設置することで、構造をシンプルにし、製造コストを低くする。また、給紙感応器が紙の進入は、紙と取紙ルートの背景区域の違いにより判断を行うため、誤作動がなくなる。また、反射する光の強さにより、紙の進入を判断すると同時に、紙の質量を確定し、様々な紙の質に相応する処理を行うことができる。 The structure is simplified and the manufacturing cost is reduced by installing the paper feed sensor on the fixed base instead of the paper mass sensor and the paper feed sensor installed separately in the prior art. Further, since the paper feed sensor makes a judgment based on the difference between the background area of the paper and the paper collection route, the malfunction does not occur. Further, it is possible to determine the entrance of the paper based on the intensity of the reflected light, and at the same time to determine the mass of the paper and perform processing corresponding to various paper qualities.

本考案による自動紙送り器給紙感知機構の構造を明確に示すために図に沿って詳細な説明を行う。図4が示すように、自動紙送り器給紙感知機構は本体を含み、本体の上に取紙ルート200及び紙回転ルート300を形成する。本体に台座110及び台座110に固定する支えスタンド120を具有する。支えスタンド120の上に信号発生器アセンブリー150を設置する。   In order to clearly show the structure of the automatic paper feeder paper feed sensing mechanism according to the present invention, a detailed description will be given with reference to the drawings. As shown in FIG. 4, the automatic paper feeder paper feed sensing mechanism includes a main body, and forms a paper collection route 200 and a paper rotation route 300 on the main body. The main body has a pedestal 110 and a support stand 120 fixed to the pedestal 110. A signal generator assembly 150 is installed on the support stand 120.

図5が示すように、支えスタンド120はプレートを折り曲げて作った構造である。支えスタンド120の側面を湾曲して延伸する二つの発生器耳121を具有し、二つの発生器耳の上にそれぞれ発生器穴122を設ける。支えスタンド120の上に、一つの発生器耳121の片側にねじりばねフック通り穴124及び、ねじりばねフック通り穴124の上にねじりばねフック穴123スを設置する。   As shown in FIG. 5, the support stand 120 has a structure formed by bending a plate. It has two generator ears 121 that curve and extend the side of the support stand 120, and a generator hole 122 is provided on each of the two generator ears. On the support stand 120, a torsion spring hook through hole 124 is installed on one side of one generator ear 121, and a torsion spring hook hole 123 is installed on the torsion spring hook through hole 124.

図7及び図8が示すように、信号発生器アセンブリー150は固定台151を含み、固定台151は円柱体157を具有し、円柱体157の片端より円柱形のねじりばね軸152を延伸する。ねじりばね軸152の外部端よりねじりばねブロック153を延伸し、ねじりばねブロック153の上にねじりばね端部挿入穴154を設ける。円柱体157の別端と中央部分にピボットブロック155を延伸する。円柱体157中央部分のピボットブロック155の上にピボット156を延伸する。円柱体157の別端にあるピボットブロック155よりピボット柱165を延伸し、ピボット柱165より短ピボット169が延伸し、該短ピボット169はピボット156と同じ軸芯である。円柱体157より延伸したピボットブロック155の片端より長方形の逸脱防止支えブロック166を延伸し、該逸脱防止支えブロック166よりピボット柱165側に逸脱防止土台ブロック167を延伸し、逸脱防止土台ブロック167より逸脱防止ブロック168を延伸する。円柱体157は、ピボット156及び短ピボット169の間より、紙押さえアーム158を延伸し、紙押さえアーム158の端部分に湾曲状を呈す紙押さえ部159を具有し、紙押さえ部159に感応器固定槽161を設ける。感応器固定槽161の中に給紙感応器162を固定し、給紙感応器162は発光部163及び感光部164を含み、給紙感応器162と給紙信号処理機(図に未掲載)は電気接続をしている。   7 and 8, the signal generator assembly 150 includes a fixed base 151. The fixed base 151 includes a cylindrical body 157, and a cylindrical torsion spring shaft 152 extends from one end of the cylindrical body 157. A torsion spring block 153 is extended from the outer end of the torsion spring shaft 152, and a torsion spring end insertion hole 154 is provided on the torsion spring block 153. A pivot block 155 is extended to the other end and the center portion of the cylindrical body 157. The pivot 156 is extended on the pivot block 155 at the center of the cylindrical body 157. A pivot column 165 extends from a pivot block 155 at the other end of the cylindrical body 157, and a short pivot 169 extends from the pivot column 165. The short pivot 169 has the same axis as the pivot 156. A rectangular departure prevention support block 166 extends from one end of the pivot block 155 extending from the cylindrical body 157, and a departure prevention base block 167 extends from the departure prevention support block 166 to the pivot column 165 side. The departure prevention block 168 is extended. The cylindrical body 157 has a paper pressing arm 158 extending between the pivot 156 and the short pivot 169, and has a paper pressing portion 159 having a curved shape at an end portion of the paper pressing arm 158. A fixed tank 161 is provided. A sheet feeding sensor 162 is fixed in a sensor fixing tank 161. The sheet feeding sensor 162 includes a light emitting unit 163 and a photosensitive unit 164. The sheet feeding sensor 162 and a sheet feeding signal processor (not shown) Has an electrical connection.

図4〜図7に示すように、信号発生器アセンブリー150はピボット156及び短ピボット169を支えスタンド120の発生器穴122と嵌合し、逸脱防止ブロック168により信号発生器アセンブリー150が支えスタンド120の発生器穴122から逸脱するのを防止する。支えスタンド120の発生器穴122に信号発生器アセンブリー150を設置する際、発生器耳121及び逸脱防止支えブロック166に具有する弾力性を利用する。台座110の給紙感応器162の下部に黒色区域を設置し、固定台151の紙押さえ部159は該黒色区域の上に押さえる。   As shown in FIGS. 4 to 7, the signal generator assembly 150 fits the pivot 156 and the short pivot 169 to the generator hole 122 of the support stand 120, and the signal generator assembly 150 is supported by the deviation prevention block 168. Deviation from the generator hole 122 is prevented. When the signal generator assembly 150 is installed in the generator hole 122 of the support stand 120, the elasticity of the generator ear 121 and the escape prevention support block 166 is used. A black area is installed below the paper feed sensor 162 of the pedestal 110, and the paper presser 159 of the fixed base 151 presses on the black area.

図4及び図5、図8が示すように、固定台151のねじりばね軸152の上にねじりばね190を設置し、ねじりばね190の片端を固定台151のねじりばね端部挿入穴154の中に挿入する。ねじりばね190の別端よりフック191を延伸し、該フック191は支えスタンド120のねじりばねフック通り穴124を通り、ねじりばねフック穴123に引っ掛ける。固定台151自身の重さは該ねじりばね190が分担するため、該紙押さえ部分159は軽く通る紙1の上を押さえ、紙1が通らない時は、軽く台座110の上の黒色区域を押さえる。   4, 5, and 8, a torsion spring 190 is installed on the torsion spring shaft 152 of the fixing base 151, and one end of the torsion spring 190 is inserted into the insertion hole 154 of the torsion spring end of the fixing base 151. Insert into. A hook 191 is extended from the other end of the torsion spring 190, and the hook 191 passes through the torsion spring hook passage hole 124 of the support stand 120 and hooks into the torsion spring hook hole 123. Since the torsion spring 190 shares the weight of the fixing base 151 itself, the paper pressing portion 159 presses the paper 1 that passes lightly, and lightly presses the black area on the base 110 when the paper 1 does not pass. .

本考案の自動紙送り器給紙感知機構は、紙1の進入がないとき、給紙感応器162の発光部163より発する光は、台座110の上にある黒色区域が吸収した後、微弱な光のみ感光部164に反射する。感光部164は相応する電気信号を発して給紙信号処理器に伝達し、給紙信号処理機は紙1の進入がないと判断する。紙1が取紙ルート200を通るとき、紙1の端が固定台151の紙押さえアーム158を押し上げ、紙押さえ部159の下部を滑り通る。紙1が給紙感応器162の下にたどりついたとき、給紙感応器162の発光部163の発する光は、紙1で反射してから感光部164に入る。紙1の表面質量が異なるため、反射する光線の強弱及び該強弱の分布状況も異なる。感光部164は紙1の表面質量と相応する電気信号を発し、給紙信号処理機に伝達する。給紙信号処理機は紙1の進入を感知し、同時に紙1の表面質量を確認する。紙1の表面質量に基づき、紙1に対する処理(インクの量)など、様々な定数を確定する。オフィス設備が紙1の一面の処理を完成し、再び紙1を後退させ、固定台151の紙押さえアーム158を押し上げ、紙押さえ部159の下よりすべり出ることができる。紙1は紙回転ルート300で回転し、再び固定台151の紙押さえ部159の下を通るとき、該自動紙送り器給紙感知機構は再び元の給紙感知過程に戻る。   In the automatic paper feeder detection mechanism of the present invention, when the paper 1 does not enter, the light emitted from the light emitting unit 163 of the paper supply sensor 162 is weak after the black area on the pedestal 110 is absorbed. Only light is reflected by the photosensitive unit 164. The photosensitive unit 164 generates a corresponding electrical signal and transmits it to the paper feed signal processor, and the paper feed signal processor determines that the paper 1 does not enter. When the paper 1 passes through the paper collection route 200, the end of the paper 1 pushes up the paper pressing arm 158 of the fixed base 151 and slides under the paper pressing portion 159. When the paper 1 arrives under the paper feed sensor 162, the light emitted from the light emitting unit 163 of the paper feed sensor 162 is reflected by the paper 1 and then enters the photosensitive unit 164. Since the surface mass of the paper 1 is different, the intensity of the reflected light and the distribution of the intensity are also different. The photosensitive unit 164 generates an electrical signal corresponding to the surface mass of the paper 1 and transmits it to the paper feed signal processor. The paper feed signal processor senses the entry of paper 1 and at the same time checks the surface mass of paper 1. Based on the surface mass of the paper 1, various constants such as processing (the amount of ink) for the paper 1 are determined. The office equipment completes the processing of one side of the paper 1, retracts the paper 1 again, pushes up the paper pressing arm 158 of the fixed base 151, and can slide out from under the paper pressing portion 159. When the paper 1 is rotated by the paper rotation route 300 and again passes under the paper pressing unit 159 of the fixed base 151, the automatic paper feeder paper feed sensing mechanism returns to the original paper feed sensing process again.

本考案の自動紙送り器給紙感知機構は、固定台151の上に設置する給紙感応器162で紙1がオフィス設備に入ったか否かを感知すると同時に、紙1の表面質量を確定する。公知技術のそれぞれに設置する紙質量感応器150’及び給紙感知器の代わりであり、自動紙送り器給紙感知機構の構造をシンプルにし、製造コストを下げる。給紙感応器162で紙1が入ったか否かを感知するのは、紙1の反射に基づくものであり、従来技術のように揺動アーム172’の動きによるものではないため、紙1の進入状況を更に正確に感知することができる。また、台座110’の上に動力アームが動くための溝111’を設置する必要もなくなる。   The automatic paper feeder paper feed sensing mechanism of the present invention senses whether or not the paper 1 has entered the office equipment with the paper feed sensor 162 installed on the fixed base 151 and at the same time determines the surface mass of the paper 1 . Instead of the paper mass sensor 150 'and the paper feed sensor installed in each of the known technologies, the structure of the automatic paper feeder paper feed sensing mechanism is simplified and the manufacturing cost is reduced. It is based on the reflection of the paper 1 that senses whether or not the paper 1 has entered by the paper feed sensor 162, and is not due to the movement of the swing arm 172 'as in the prior art. The approach situation can be detected more accurately. Further, it is not necessary to install a groove 111 'for moving the power arm on the pedestal 110'.

以上の実施例による本考案の詳細な説明は本考案の範囲を制限するものではない。固定構造の変更及び調整を行うことができ、これらの変更および調整を行っても本考案の重要な意義は失われず、本考案の範囲に含まれる。例えば、台座110にある黒色区域の代わりに高い光反射能力を具有する光反射シート或いは光反射層を使用することができる。この時、給紙信号処理器の“紙有り”及び“紙無し”の認定基準を新たに設定しなおす必要がある。固定台151の紙押さえ部159が台座110の黒色区域を軽く押さえるのを、給紙感応器162が台座110の黒色区域を軽く押さえる、に変更することもできる。   The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. The fixing structure can be changed and adjusted, and even if these changes and adjustments are made, the significance of the present invention is not lost, and is included in the scope of the present invention. For example, a light reflecting sheet or a light reflecting layer having a high light reflecting ability can be used instead of the black area on the pedestal 110. At this time, it is necessary to newly set the certification criteria for “paper present” and “paper absent” for the paper feed signal processor. The paper pressing unit 159 of the fixed base 151 can be changed from lightly pressing the black area of the pedestal 110 to the paper feeding sensor 162 lightly pressing the black area of the pedestal 110.
