Abstract

본 발명은 잉크 제트 프린터나 팩시밀리 등에 사용되는 잉크 카트리지의 장착 여부와 그 종류, 잉크의 잔량등을 감지하는 잉크 카트리지 감지 장치에 관한 것이다.The present invention relates to an ink cartridge detection device for detecting whether or not an ink cartridge used for an ink jet printer, a facsimile, etc. is mounted and its type, the remaining amount of ink, and the like.

종래에 잉크 카트리지의 장착 여부나 잉크 잔량을 감지하기 위한 장치로서는 카트리지 감지 스위치나 광센서등을 이용하고, 또 잉크를 사용할 때마다 픽셀 카운터를 동작시켜서 픽셀 카운트값을 가지고 잉크 사용량을 계속 연산하여 사용량 대비 잔량을 감지하고 있다.Conventionally, as a device for detecting whether or not an ink cartridge is mounted or a remaining amount of ink, a cartridge detection switch or an optical sensor is used, and a pixel counter is operated every time ink is used, It is detecting the contrast level.

그러나, 상기한 종래의 감지장치 구조에서는 잉크 카트리지의 장착 오차, 상기 발광 및 수광 경로의 차이, 발광된 빔의 퍼짐 등에 의해서 정확한 카트리지 장착 및 종류 검출이나 잉크 잔량 검출을 어렵게 하고 있다.However, in the above conventional sensing device structure, it is difficult to accurately mount a cartridge, to detect a type, and to detect the remaining amount of ink, due to mounting error of the ink cartridge, difference between the light emission and the light receiving path, and spread of the emitted light.

본 발명은 잉크 카티리지 탱크(2)의 장착 유무 검출을 위한 발광소자(4a,4a´)의 광경로(4e,4e´)를 좁혀주고 그 직선성을 확보하여 정확한 검출이 가능하게 하는 한편, 잉크 잔량 검출용 발광조사(4b)의 배치를 수광소자(4c)와 동일한 폭의 광로와 반사층과의 거리를 갖게 배치함으로써, 상기한 종래의 문제점을 해결하고 정확한 잉크 카트리지 탱크의 장착 유무, 종류, 잉크 잔량 검출을 수행할 수 있도록 한 잉크 카트리지 감지 장치를 제공한다.The present invention narrows down the optical paths 4e and 4e 'of the light emitting devices 4a and 4a' for detecting the presence or absence of the mounting of the ink cartridge tank 2 and secures the linearity thereof to enable accurate detection, The disposition of the light emission illuminations 4b for detecting the remaining amount of ink is arranged so as to have a distance between the light path and the reflective layer having the same width as that of the light receiving element 4c, The present invention provides an ink cartridge detection apparatus capable of performing ink level detection.
