Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、印刷装置の用紙検出方式に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a paper detection method for a printing device.
従来、この種の用紙検出方式はマイクロスイッチによる
メカニカルセンス方式、フォトカップラによる光センス
方式がある。Conventionally, this type of paper detection method includes a mechanical sense method using a microswitch and a light sense method using a photocoupler.
メカニカルセンス方式は用紙挿入時に抵抗感があり、単
票用紙を多く使用する、例えばワープロの、業務では使
い難さがあり、無接触な用紙検出ではないという欠点が
ある。The mechanical sense method has the disadvantage that there is a feeling of resistance when paper is inserted, that it is difficult to use in business applications such as word processors that use a lot of cut paper, and that paper detection is not contactless.
一方、元センス方式は無接触検出ではめるが、この方式
はフォトダイオードにより光を用紙に送り、これの反射
光を７オトセンサで検出する方式をとるため、反射率の
悪い用紙はうまく検出できないという欠点を１する。反
射率の悪い用紙とは例えば色のついた用紙、あらかじめ
けい線やワク組みを刷り込んである用紙である。On the other hand, the original sense method uses non-contact detection, but this method uses a photodiode to send light to the paper, and the reflected light is detected by a 7-photo sensor, so paper with poor reflectance cannot be detected properly. Increase the disadvantage by 1. Paper with poor reflectivity is, for example, colored paper or paper on which cross-cut lines or creases have been printed in advance.
本発明の用紙検出方式は、光を送出する光源と、元を受
け取り電気信号に変換する受光素子と、光源および受光
素子と用紙通路に対して反対側に設けられた光を伝達す
る元ファイバを有している。The paper detection method of the present invention includes a light source that sends out light, a light receiving element that receives the signal and converts it into an electrical signal, and a source fiber that transmits the light that is provided on the opposite side of the paper path from the light source and the light receiving element. have.
次に本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例である。１は光源、２は受光
素子、３は元ファイバを示す。第１図は用紙無しの場合
を示し、１を発した光は３を通過して２へ人力し２によ
り電気信号に変換される。FIG. 1 shows an embodiment of the present invention. 1 is a light source, 2 is a light receiving element, and 3 is an original fiber. FIG. 1 shows the case when there is no paper, and the light emitted from 1 passes through 3 and is input to 2, where it is converted into an electrical signal.
第２図は用Ｍ翁９の場合を示す。４は用紙を示し、第１
図における元の伝達糸が遮断される。これにより２へ元
が入力されないので２の出力は、第１図とは違ったもの
となり用紙の有無が判断できる。FIG. 2 shows the case of a working man 9. 4 indicates the paper, the first
The original transmission thread in the figure is interrupted. As a result, the source is not input to 2, so the output of 2 is different from that shown in FIG. 1, and the presence or absence of paper can be determined.
以上説明したように本発明は、光ファイバを使用するこ
とにより、無接触検出で、かつ反射率の恋い用紙を検出
できる効果がある。As explained above, the present invention has the advantage of being able to detect paper with low reflectance through non-contact detection by using an optical fiber.
