Abstract

<P>PROBLEM TO BE SOLVED: To realize detection of a residual ink ribbon and secure detection of loading of the ribbon in a small and low cost device in an image printer using the roll type ink ribbon. <P>SOLUTION: A built-in sensor 10 is positioned opposite to a slit-like hole 9 provided to a compartment section 6. As the plurality of slit-like holes 9 are arranged in the rotary direction of the compartment section 6, the sensor 10 can detect one revolution of a ribbon core 4 by detecting all the slit-like holes 9. By counting an amount of a rotation (the number of steps) of a stepping motor for conveying the ribbon at a time when the ribbon core 4 is rotated for one revolution, a length L of the ribbon drawn for one revolution thereof can be calculated. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明は、ロール状のインクリボンを使用したファクシミリ、プリンター等の画像印刷装置において、インクリボンの残量検出及びリボン装着の確実性検出を小型、及び安価にて実現することに関するものである。   The present invention relates to realizing detection of the remaining amount of ink ribbon and the reliability of ribbon mounting at a small size and at low cost in an image printing apparatus such as a facsimile or printer using a roll-shaped ink ribbon.

ロール状インクリボンを使用したファクシミリ、プリンター等の画像印刷装置では、図４で示す様にインクリボンを、未使用部分を巻きつけた供給側と使用済みリボンを巻き取る側の２本の軸に巻きつけた構造が知られている。   In an image printing apparatus such as a facsimile or a printer that uses a roll-shaped ink ribbon, as shown in FIG. 4, the ink ribbon is placed on two shafts on the supply side where the unused portion is wound and on the side where the used ribbon is wound. A wound structure is known.

上記装置ではインクリボンを記録紙に転写させるためのサーマルヘッドや、プラテンローラー等をリボンの周辺に具備し、印字時にはプラテンローラーにより記録紙をとリボンを圧接しながら紙送りを行い、印字の速度に合わせ、巻き取り側のリボン軸を回転させ使用済みのリボンを連続的に巻き取っていくような構造が一般的である。   In the above device, a thermal head for transferring the ink ribbon to the recording paper, a platen roller, etc. are provided around the ribbon, and during printing, the recording paper is fed to the ribbon while pressing the recording paper against the ribbon, and the printing speed is increased. In general, a structure is used in which a ribbon shaft on the winding side is rotated to continuously wind up used ribbons.

上記装置にてインクリボンの残量を確認するためにはリボンの使用量を何らかの方法により検出する必要がある。   In order to check the remaining amount of the ink ribbon with the above apparatus, it is necessary to detect the amount of ribbon used by some method.

従来はこの使用量を検出するために、リボン軸同軸の外側にリボンの回転を検出するスリット状孔を持つ円盤とセンサーを設けたエンコーダー装置を取り付けることにより、リボンの回転量をカウントし、それを元にリボンの残量を算出している（例えば特許文献１，２参照。）。図５に従来技術の一般的な構造模式図を示す。回転を検出するためのスリット状の孔３を持つ円盤１やセンサー２等の回転量検出装置をインクリボン１が巻回されているリボンコア４とは別体の装置本体５内部に設置されている。   Conventionally, in order to detect this amount of use, the rotation amount of the ribbon is counted by attaching a disk with a slit-like hole that detects the rotation of the ribbon on the outside of the ribbon axis and an encoder device provided with a sensor. Is used to calculate the remaining amount of ribbon (see, for example, Patent Documents 1 and 2). FIG. 5 shows a general structural schematic diagram of the prior art. A rotation amount detection device such as a disk 1 or a sensor 2 having a slit-like hole 3 for detecting rotation is installed inside a device main body 5 separate from the ribbon core 4 around which the ink ribbon 1 is wound. .

又、別方法として、上記と同様のエンコーダー装置を設け、リボンの回転周期の変化（時間）によりリボンの残量を検出する方法がある（例えば特許文献３, ４参照。）。
特開平４−３３１１７８号公報 特開２００１ー４７７１７号公報 特開平６−４７９７７号公報 特開平１０−２４４７２４号公報 As another method, there is a method in which an encoder device similar to the above is provided and the remaining amount of the ribbon is detected based on a change (time) in the rotation period of the ribbon (see, for example, Patent Documents 3 and 4).

ところが、上記の従来の装置では、装置本体内部に上記装置を内蔵するための余分なスペースや回転検出用のスリット状の孔を持つ円板等の余分な部品を設置する必要があり、装置サイズが必要以上に大きくなったり、コスト面でも部品点数増加や精密部品のための製造コストが上がってしまう問題点がある。   However, in the above conventional apparatus, it is necessary to install an extra part such as a disk having an extra space for incorporating the above apparatus inside the apparatus main body or a slit-like hole for detecting rotation. However, there is a problem that the cost becomes larger than necessary, the cost increases, and the manufacturing cost for precision parts increases.

この発明の目的は、リボンが消費されるとリボンの一定回転数当たりの送り量が変化し、それに伴いその送り量からインクリボンの残量を検出するようにして、小型、安価にリボンの残量検出ができるリボン支持構造を提供することにある。   The object of the present invention is to reduce the amount of ribbon remaining at a small size and at low cost by detecting the remaining amount of ink ribbon from the amount of feed when the ribbon is consumed. An object of the present invention is to provide a ribbon support structure capable of detecting the amount.

この発明は、ロール状のインクリボンを回転可能に支持するリボン支持構造において、供給側又は巻き取り側リボンコアの端部に設けられている仕切りに、回転検出用の孔部又は突起を設け、かつ、そのコアを支持するための軸受け内部に、前記回転検出用の孔部又は突起を検出するためのセンサー又はスイッチを設けたことを特徴としている。   The present invention provides a ribbon support structure for rotatably supporting a roll-shaped ink ribbon, wherein a hole provided for rotation detection or a protrusion is provided in a partition provided at an end of a supply-side or take-up-side ribbon core, and In addition, a sensor or a switch for detecting the rotation detection hole or protrusion is provided inside a bearing for supporting the core.

本発明では、センサーやスイッチにより、リボンコア端部に設けられている仕切りの孔部又は突起を検出するようにしているため、リボンの回転数を簡単に検出可能である。したがって、ステッピングモータ等によりリボンの送りを行うようにしておけば、リボンが一定回転数（例えば１回転）だけ回転したときのリボン送り量を簡単に知ることができる。リボン送り量が分かれば、そのときのリボン巻き外径がわかるから、さらに、この外径よりリボン残量を計算により求められる。これにより、スリット状の孔を持つ円板を設けなくても簡単な構造で、リボン残量を簡単に知ることが出来る。また、リボンが一定回転したときのステッピングモータの送り量（ステップ数）により、そのときのリボン残量を絶対的に知ることが出来るため、リボンを装置全体から外して、再び装着したときでも、残量を知ることが出来る利点がある。   In the present invention, since the hole or protrusion of the partition provided at the end of the ribbon core is detected by the sensor or the switch, the rotation speed of the ribbon can be easily detected. Therefore, if the ribbon is fed by a stepping motor or the like, it is possible to easily know the ribbon feeding amount when the ribbon is rotated by a certain number of revolutions (for example, one revolution). If the ribbon feed amount is known, the outer diameter of the ribbon winding at that time can be known, and further, the remaining amount of ribbon can be calculated from this outer diameter. Accordingly, the remaining amount of the ribbon can be easily known with a simple structure without providing a disk having a slit-like hole. Also, since the remaining amount of ribbon at that time can be absolutely known by the feed amount (number of steps) of the stepping motor when the ribbon rotates at a constant speed, even when the ribbon is removed from the entire device and attached again, There is an advantage that the remaining amount can be known.

また、リボンコア端部の仕切りに、回転検出用の孔部又は突起を設けていることにより、検出対象部品を別途設ける必要が無く、構造が簡単になる。   Further, since the rotation detection hole or protrusion is provided in the partition of the ribbon core end portion, it is not necessary to separately provide a detection target component, and the structure is simplified.

さらに、リボンコアが正しくセットされていなければ回転検出用の孔部又は突起を設けていることにより、検出対象部品を別途設ける必要がなく、構造が簡単になる。   Furthermore, if the ribbon core is not set correctly, the rotation detection hole or projection is provided, so that it is not necessary to separately provide a detection target component, and the structure is simplified.

さらに、リボンコアが正しくセットされていなければ回転検出用の孔部又は突起を検出出来ないことになるから、リボンコアが正しくセットされているかどうかを簡単に検出可能である。正しくセットされていないときは警報を行うことにおより、ユーザに知らせることが出来る。   Furthermore, if the ribbon core is not set correctly, the rotation detection hole or protrusion cannot be detected, so it is possible to easily detect whether the ribbon core is set correctly. When it is not set correctly, the user can be notified by issuing an alarm.

この発明によれば、検出装置がインクリボン内部に位置する構成にできるため、装置が小型化される。又、回転検出構造をリボンコアに一体成形することにより装置本体側に同構造を設ける必要が無く、部品点数の削減が図れる。   According to this invention, since the detection device can be configured to be located inside the ink ribbon, the device can be miniaturized. Further, by integrally forming the rotation detection structure on the ribbon core, it is not necessary to provide the same structure on the apparatus main body side, and the number of parts can be reduced.

また、リボンが１回転したときのステッピングモータの送り量（ステップ数）により、そのときのリボン残量を絶対的に知ることが出来るため、リボンを装置本体から外して、再び装着したときでも、残量を正確に知ることが出来る利点がある。   Moreover, since the remaining amount of the ribbon at that time can be absolutely known from the feed amount (number of steps) of the stepping motor when the ribbon rotates once, even when the ribbon is detached from the apparatus main body and attached again, There is an advantage that the remaining amount can be accurately known.

以下に、本発明の実施形態に係るリボン支持装置について図面を参照しつつ詳細に説明する。図１、図２は、それぞれリボン支持構造図とその拡大図を示す。 インクリボン支持構造体は、インクリボン１と、中空のリボンコア４を備えている。インクリボン１は、リボンコア４にインクリボンをロール状に巻回して構成されている。リボンコア４の一端部より内側には仕切部６が設けられている。この仕切部６には、スリット状の孔部９が回転方向に沿って多数設けられている。仕切り部６の外側には、回転検出用反射型センサー１０を内蔵した、リボンコア内径部に嵌合しリボンコア４を支持するためのリボンコア軸受け（スプール）１１が設けられている。該軸受け１１と反対側には着脱自在のリボンコア軸受け（スプール）８が設けられている。   Hereinafter, a ribbon support device according to an embodiment of the present invention will be described in detail with reference to the drawings. 1 and 2 show a ribbon support structure diagram and an enlarged view thereof, respectively. The ink ribbon support structure includes an ink ribbon 1 and a hollow ribbon core 4. The ink ribbon 1 is configured by winding an ink ribbon around a ribbon core 4 in a roll shape. A partition 6 is provided inside the one end of the ribbon core 4. The partition 6 is provided with a large number of slit-shaped holes 9 along the rotation direction. Outside the partition 6, a ribbon core bearing (spool) 11 that fits in the inner diameter of the ribbon core and supports the ribbon core 4 is provided. A removable ribbon core bearing (spool) 8 is provided on the side opposite to the bearing 11.

図２において、リボンコア軸受け１１は、その外径がリボンコアの内径に略等しく設定され、内蔵されているセンサー１０は、仕切り部６の中心からやや偏心した位置に設けられている。また、このセンサー１０はリボンコア４の端部と仕切り板６との間に位置し、リボンコア軸受け１１内に設けられているため、リボン支持装置全体の大きさは大きくなっていない。スリット状孔部９は仕切り部６の回転方向に多数設けられているため、センサー１０がこのスリット状孔部９の全数を検出することでリボンコア４の１回転を検出することが出来る。コア４の１回転のみを検出する場合にはスリット状孔部の数は多くする必要は無い。また、リボンコア４の一定回転検出の場合には、精度を高くするために、このスリット状孔部の数をなるべく多くすることが望ましい。   In FIG. 2, the outer diameter of the ribbon core bearing 11 is set to be substantially equal to the inner diameter of the ribbon core, and the built-in sensor 10 is provided at a position slightly decentered from the center of the partition portion 6. Further, since the sensor 10 is located between the end of the ribbon core 4 and the partition plate 6 and is provided in the ribbon core bearing 11, the overall size of the ribbon support device is not increased. Since many slit-shaped holes 9 are provided in the rotation direction of the partition 6, the sensor 10 can detect one rotation of the ribbon core 4 by detecting the total number of the slit-shaped holes 9. When only one rotation of the core 4 is detected, it is not necessary to increase the number of slit-shaped holes. Further, in the case of detecting the constant rotation of the ribbon core 4, it is desirable to increase the number of slit-like holes as much as possible in order to increase the accuracy.

図３はスリット状孔部９を有する仕切り部６の側面形状を示している。実際の使用時には、まず最初に、前記供給側のインクリボン１に前記軸受け８を差込、次に、そのリボン１を、装置本体に固定されたセンサー１０を内蔵した軸受け１１に差込み装着する。印字を行うときのリボン消費時においては供給側のリボン１は、リボン送りステッピングモータが設けられているリボン送り部１２により一定量ずつ送り出される。このときセンサー１０は、回転中のリボンコア内部にある仕切り部６のスリット状孔部９を検出してリボンコアが回転していることを確認する。このとき、センサー１０の出力がon-offの状態を繰り返していれば正規品である。もし、そうでなければ不正品であるか、又はリボンが正しく装着されていない事になるため、使用者に表示や音などの注意を促す警告を発する。また、スリット状孔部９の数を計数し、その数がリボン１の１回転に達したかどうかを検出する。なお、スリット状孔部９に代えて突起状の段差を設けてもよい。また、この検出には反射型フォトセンサーに代えて、透過型のセンサーやスイッチを用いてもよい。そして、その１回転した時のリボン送り用ステッピングモータの送り量（ステップ数）をカウントする事により、リボン１回転で巻き出されたリボンの長さＬを算出する事が出来る。   FIG. 3 shows a side shape of the partition 6 having the slit-shaped hole 9. In actual use, the bearing 8 is first inserted into the ink ribbon 1 on the supply side, and then the ribbon 1 is inserted into and mounted on a bearing 11 incorporating a sensor 10 fixed to the apparatus main body. When the ribbon is consumed for printing, the ribbon 1 on the supply side is fed out by a certain amount by a ribbon feeding unit 12 provided with a ribbon feeding stepping motor. At this time, the sensor 10 detects the slit-shaped hole 9 of the partition 6 inside the rotating ribbon core and confirms that the ribbon core is rotating. At this time, if the output of the sensor 10 repeats the on-off state, it is a regular product. If not, it is an improper product or the ribbon is not properly attached, so that a warning is issued to call the user attention such as display or sound. Further, the number of slit-like hole portions 9 is counted, and it is detected whether or not the number has reached one rotation of the ribbon 1. In place of the slit-shaped hole 9, a protruding step may be provided. For this detection, a transmissive sensor or switch may be used instead of the reflective photosensor. The length L of the ribbon unwound by one rotation of the ribbon can be calculated by counting the feed amount (number of steps) of the ribbon feeding stepping motor at one rotation.

Ｌ＝ステップ数（モーターの送り量）＊ローラーのモーター１ステップあたりの送り量……（１）
又、このときのリボン巻き外径Ｄは
Ｄ＝Ｌ／π……（２）
リボンの外径が判れば一般的に知られているロール巻きの長さの計算式よりリボン残量ＬＬを算出することが出来る。以下に一般的な算出方法を参考例として示す。 L = number of steps (motor feed) * feed per roller motor step ... (1)
The ribbon winding outer diameter D at this time is D = L / π (2)
If the outer diameter of the ribbon is known, the remaining ribbon amount LL can be calculated from a generally known formula for calculating the winding length of the roll. A general calculation method is shown below as a reference example.

ＬＬ＝（π（Ｄ2 ーd2）／４）／ｔ……（３） Ｄ＝リボン外径、ｄ＝リボンコア外径、ｔ＝リボン厚み
以上の様にしてリボン残量ＬＬを求めこの残量ＬＬが所定値以下になるとユーザに対してブザーや表示により知らせる。本実施形態では、リボンが１回転したときのステッピングモータの送り量（ステップ数）により、そのときのリボン残量を絶対的に知ることが出来るため、リボンを装置本体から外して、再び装着したときでも、残量を知ることが出来る利点がある。 LL = (π (D2−d2) / 4) / t (3) D = ribbon outer diameter, d = ribbon core outer diameter, t = ribbon thickness The ribbon remaining amount LL is obtained as described above, and this remaining amount LL. When the value falls below a predetermined value, the user is notified by a buzzer or display. In this embodiment, since the remaining amount of the ribbon at that time can be absolutely known from the feed amount (number of steps) of the stepping motor when the ribbon makes one rotation, the ribbon is removed from the apparatus main body and mounted again. Even when there is an advantage of knowing the remaining amount.

なお、他の方法として、上記計算によらず、あらかじめリボンの消費量又は残量に対するステッピングモータ送り量ステップ数の関係を実験によりグラフ化しておき、計数したステップ数の留積値より、グラフから消費量又は、残量を読み取る方法もある。図６にグラフ化した場合の実施例を示す。実施例では横軸にステッピングモータの送りステップ数の留積値、縦軸にリボン残量を表している。例えば、リボン残量が１０ｍとなった時に残量表示を表示したい場合、グラフの縦軸１０ｍのところの横軸と交差する縦軸のモータ送りステップ数に達したときに表示をする。本実施形態のリボン支持構造（ロール状の記録紙等の支持構造）は、あらゆる装置に適用可能であって、ロール状の記録紙やリボン残量を高精度に検出可能である。例えばファクシミリに適用した場合、ステッピングモータの１ステップあたりのリボン送り量は１／７．７ｍｍから１／１５．４ｍｍであるが、この長さは、用紙１枚印字する長さに対して充分に小さい為、正確に残量検出を行うことが出来る。   As another method, the relationship between the stepping motor feed amount step number with respect to the consumption amount or remaining amount of the ribbon is graphed in advance by an experiment, and the graph is obtained from the residual value of the counted number of steps. There is also a method of reading the consumption amount or the remaining amount. FIG. 6 shows an embodiment in the case of graphing. In the embodiment, the horizontal axis represents the yield value of the number of feeding steps of the stepping motor, and the vertical axis represents the remaining amount of ribbon. For example, when it is desired to display the remaining amount display when the remaining amount of the ribbon reaches 10 m, the display is performed when the motor feed step number on the vertical axis intersecting the horizontal axis at the vertical axis 10 m of the graph is reached. The ribbon support structure (support structure for roll-shaped recording paper, etc.) of the present embodiment can be applied to any apparatus, and can detect the roll-shaped recording paper and the remaining amount of ribbon with high accuracy. For example, when applied to a facsimile, the ribbon feed amount per step of the stepping motor is from 1 / 7.7 mm to 1 / 15.4 mm, but this length is sufficiently longer than the length for printing one sheet of paper. Since it is small, the remaining amount can be accurately detected.
