った。qll Conventionally, inkjet printers have been equipped with a member that presses the ink bag in the ink cassette in order to detect when the ink in the ink cartridge is running out, and this suppressing member operates a switch when the ink runs out. (Japanese Utility Model Publication No. 54-114956), but since a suppressing member is used, the ink supply side is pressurized.
The problem was that the nozzle part was prone to dripping, and since detection was based on turning on and off a switch, it was impossible to prevent malfunctions.
目 的

する。Purpose The present invention has been made in view of the above circumstances, and there is no fear of liquid dripping at the nozzle portion, and the multi-step detection display of the remaining ink level makes it possible to reduce the risk of ink running out compared to a case where only an ink running out indication is displayed. An object of the present invention is to provide an ink remaining amount detection device for an inkjet printer that is free from display malfunctions.

これが折れ曲がったり、倒れたりしないためのガイドで
ある。FIG. 1 is a diagram showing the overall configuration of the ink remaining amount detection device according to the present invention, in which 1 is an ink cassette receiving part into which ink cartridges 1 and 2 are loaded, 3 is an ink bag stored in the ink cassette 2, Heat seal part 4 on the bottom mating surface of the ink bag
The pattern code imparting plate 5 is formed by vertically bending a part of the plate or by adding another member. Therefore, when the ink in the ink bag 3 decreases due to ink consumption, the pattern code applying plate 5 moves downward and reaches the bottom when the ink is exhausted. Then, the pattern code on the pattern code applying plate 5 is read by a pattern code detection sensor 6 through a notch 7 provided in the ink cartridge 1 to detect the remaining amount of ink. 8, since the pattern code giving plate 5 is extremely thin,
This is a guide to prevent it from bending or falling.
第２図は、第１図のパターンコード付ケ・板の一例を示

構成している。FIG. 2 is a detailed view showing an example of the pattern coded card and plate shown in FIG. 1, and the pattern code is made of magnetic material 11.degree. 12.

サ６に相当する。FIG. 3 is a diagram showing an example of the arrangement of pattern code detection sensors, where ]-3 and 14 are magnetic sensors that detect the magnetic bodies 1, 1 and 12 that constitute the pattern code, and the sensors shown in FIG. Corresponds to 6.

４の出力は表１のようになる。Now, as the ink decreases, the pattern code application plate moves downward, and the time when the magnetic sensors 13 and 14 detect a magnetic substance is expressed by the logical value ], and the time when no magnetic substance is detected is expressed by the logical value O. Table 1 shows the outputs of the sensors 13 and 13-4 when the sensors 13 and 13-4 reach the positions A, B, C, and D shown in FIG.
そして各インクレベルを表１に示すように、′満″。As shown in Table 1, each ink level is 'full'.
″中ｒｚｒｒやや少ｎ、ｕ欠″の４段階に表示すれば、
２個のセンサで４段階のインク残量検知表示ができる。If it is displayed in 4 levels: ``medium rzrr slightly n, u missing'',
The remaining ink level can be detected and displayed in four stages using two sensors.
同様にセンサをｎ個使用すれば２ｎ段階のインク残量表

段階表示が可能となる。Similarly, if n sensors are used, the remaining ink amount can be displayed in 2n stages. In this way, multi-level ink level detection and display is possible, and as compared to the conventional method where only the ink out is displayed, it is possible to eliminate malfunctions in the ink out display. In addition, since it is possible to display ink levels in multiple levels using only a few sensors, it is possible to display multiple levels at low cost.
パターンコードの他の例を第４〜６図に示す。Other examples of pattern codes are shown in FIGS. 4-6.

なる。- As described above, according to the present invention, since the remaining ink level is detected and displayed in multiple stages, the malfunction of the ink out detection display is less likely to occur, compared to the case where only out of ink is detected and displayed. Furthermore, since the coded multi-stage display is used, there is no need to worry about adjustments or malfunctions compared to analog multi-stage displays, and since only a small number of sensors are required, multi-stage display can be performed at low cost.
また従来のようにインク袋抑圧部材を設けていないので
、ノズル部での液ダレの心配もない。Furthermore, unlike the conventional ink bag suppressing member, there is no need to worry about liquid dripping at the nozzle.
