본 고안은 전자사진식 복사기에 있어서 현상시 토너(Toner)를 사용하는 복사기에 관한 것으로 특히 현상에 사용된 폐토너의 량을 검지하여 표시하는 장치에 관한 것이다.The present invention relates to a copier using a toner during development in an electrophotographic copier, and more particularly, to an apparatus for detecting and displaying an amount of waste toner used for development.
통상적으로 전자사진식 복사기에는 현상시 수성잉크로 복사물을 현상하는 습식복사기와 현상시건식 토너로 복사물을 현상하는 건식복사기가 있다.In general, an electrophotographic copier includes a wet copier for developing a copy with an aqueous ink during development and a dry copier for developing a copy with a dry toner during development.
상기 건식복사기에는 현상에 사용된 폐토너의 량을 검지하는 종래의 폐토너량 검지장치는 제 1 도와 같이 발광소자(LED1)와 수광소자(DH1)를 폐토너통(10)의 안쪽 상부에 밀착시켜 오거(20)를 통해 빠져나오는 현상에 사용되어 못쓰게된 토너가 폐토너통(10)에 떨어져 수, 발광소자 위치까지 차게되면, 투명프라스틱으로 되어진 폐토너통이 불투명하게 된다.Conventional waste toner amount detection device for detecting the amount of waste toner used for development in the dry copying machine is to close the light emitting element (LED1) and the light receiving element (DH1) to the inner upper portion of the waste toner container 10 as the first degree When the waste toner used in the phenomenon coming out through the auger 20 falls to the waste toner box 10 and fills up to the position of the light emitting device, the waste toner box made of transparent plastic becomes opaque.
그러면 발광소자(LED1)로 부터 발생되는 광신호는 이때 폐토너는 검은색 이므로 폐토너통에서 반사가 되지 않고 빛을 흡수하므로 포토트랜지스터(PH1)에는 광신호가 입력되지 않아 오프상태가 된다. 이때 마이콤(30)은 저항(R2)을 통해 인가되는 제1전원(Vcc)에 의해 하이논리상태를 입력하게 되어 폐토너가 가득찼다는 경고표시로 발광소자(LED2)를 접동시킨다.Then, the light signal generated from the light emitting device LED1 is black because the waste toner is black so that the light is not reflected from the waste toner box and absorbs the light, so the light signal is not input to the phototransistor PH1 and thus is turned off. At this time, the microcomputer 30 enters the high logic state by the first power supply Vcc applied through the resistor R2 and slides the light emitting device LED2 as a warning indication that the waste toner is full.
그러나 상기와 같이 종래의 폐토너량 검지장치는 폐토너가 전부 폐토너통으로 들어가지 못하고 밖으로 새어 나오거나 기계내부에서 토너가 비산 또는 가득찬 토너통을 운용자가 빼내어 폐토너를 버린후 다시 폐토너통을 다시 장착할 경우 폐토너통이 더럽혀지거나 발광 소자와 포토트랜지스터의 센싱부분이 톤로 오염되어 있을때가 많아 광신호가 폐토너통(10)에서 반사되지 못함으로 마이콤(30)은 폐토너통(10)에 폐토너가 가득찬 것으로 인지하여 발광소자(LED2)를 점등시키는 오동작을 하게되는 문제점이 있었다.However, in the conventional waste toner amount detecting device as described above, the waste toner container does not enter the waste toner box entirely and leaks out, or the operator removes the toner container from which the toner is scattered or filled from the inside of the machine and discards the waste toner again. In this case, the waste toner box is dirty or the sensing parts of the light emitting element and the phototransistor are contaminated with tones, so the optical signal is not reflected from the waste toner box 10. Thus, the microcomputer 30 is a waste toner box 10. Recognizing that the waste toner is full, there was a problem that the malfunction to turn on the light emitting device (LED2).
따라서 본 고안의 목적은 폐토너통의 오염이나 토너감지센서의 오염에 무관하게 폐토너통의 폐토너량을 검지하여 경로할 수 있는 폐토너량 검지장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a waste toner amount detection device capable of detecting and routing the waste toner amount of the waste toner box regardless of contamination of the waste toner box or contamination of the toner detection sensor.
이하 본고안을 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본고안의 폐토너량 검지장치로서, 오거(20)를 통해 유입되는 폐토너를 저장하기 위한 폐토너통(10)와, 상기 폐토너통(10)의 상측벽면에 일정간격으로 부착되어 1전원(15)을 제1접속구(13)를 통해 폐토너의 축적상태에 따라 제2접속구(14)를 통해 토너감지 신호를 발생하는 제1, 2금속판(11, 12)과, 상기 제2접속구(14)로 부터 토너감지 신호를 입력하여 소정증율로 증폭하는 증폭기(40)와, 상기 증폭기(40)로 부터 증폭된 토너감지신호를 입력하여 제2전원(16)과 비교하는 비교기(50)와, 폐토너통(10)의 폐토너 회수경보를 발생하는 발광소자(LED1)와, 복사기 시스템을 제어하며 상기 비교기(50)와 출력을 입력하여 검사함으로서 폐토너통(10)의 축적된 폐토너량을 감지한 다음 폐토너의 측적상태에 따라 상기 발광소자를 구동하는 마이콤(30)으로 구성한다.1 is a waste toner amount detection device of the present disclosure, which is attached to the waste toner container 10 for storing the waste toner flowing through the auger 20 and the upper wall surface of the waste toner container 10 at regular intervals. First and second metal plates 11 and 12 generating a toner detection signal through the second connector 14 in accordance with the accumulated state of the waste toner through the first power outlet 15 through the first connector 13, and the second An amplifier 40 for inputting the toner detection signal from the connector 14 and amplifying the toner detection signal at a predetermined increment; and a comparator 50 for inputting the toner detection signal amplified from the amplifier 40 and comparing it with the second power source 16. ), A light emitting device (LED1) for generating a waste toner recovery alarm of the waste toner container (10), a copier system and controlling the comparator 50 and the output to check the accumulation of the waste toner container (10) After sensing the waste toner amount, the waste toner is composed of the microcomputer 30 driving the light emitting device according to the measurement state of the waste toner.
상술한 구성에 의거하여 본고안을 상세히 설명한다.Based on the above-described configuration, the present invention will be described in detail.
복사기 시스템작동시 복사물을 현상하게 되면 현상에 사용된 후 사용이 불가하게된 폐토너는 회전하고 있는 오거(20)를 따라 폐토너통(10)으로 흘러들어가 측적되게 된다.When the copy is developed during operation of the copier system, the waste toner, which is not used after development, flows into the waste toner container 10 along the rotating auger 20 to be measured.
상기 폐토너가 폐토너통의 제1, 2금속판의 위치까지 축적하게 되면 제1전원(15)은 상기 폐토너가 제1금속판(11)과 제2금속판(12)사이에 하나의 저항체로 작용하는 전류통로를 통해 전압 감쇄되어 토너감지 신호를 제1접속구(14)를 통해 증폭기(30)로 인가된다.When the waste toner accumulates to the positions of the first and second metal plates of the waste toner box, the first power source 15 acts as a resistor between the first and second metal plates 11 and 12. The voltage is attenuated through the current path, and the toner detection signal is applied to the amplifier 30 through the first connector 14.
이때 증폭기(40)는 상기 제2접속구(14)를 통해 토너감지 신호를 입력하여 소정 증폭율로 증폭한 다음 비교기(50)로 출력한다. 그러면 상기 증폭기(40)로 부터 증폭되어진 토너감지 신호를 입력하는 비교기(50)는 상기 토너감지 신호를 제2전원(16)의 전압레벨과 비교하여 비교신호를 마이콤(30)으로 출력한다.At this time, the amplifier 40 inputs the toner detection signal through the second connector 14 and amplifies the toner detection signal at a predetermined amplification ratio and then outputs it to the comparator 50. Then, the comparator 50 for inputting the toner detection signal amplified from the amplifier 40 compares the toner detection signal with the voltage level of the second power supply 16 and outputs the comparison signal to the microcomputer 30.
이때 비교신호는 상기 증폭되어진 토너감지 신호가 제2전원(16)보다 클 경우엔 하이논리 상태를 갖게되면 이와 반대로 증폭되어진 토너감지 신호가 제2전원(16)보다 작을 경우에는 로우논리 상태를 갖는다.At this time, the comparison signal has a high logic state when the amplified toner detection signal is larger than the second power source 16 and has a low logic state when the amplified toner detection signal is smaller than the second power source 16. .
상기 비교기(50)로 부터 비교신호를 입력하는 마이콤(30)은 상기 비교신호의 논리상태를 검사하여 폐토너의 축적상태를 감지한 다음 상기 폐토너의 축적상태에 따라 발광소자(LED1)를 구동한다.The microcomputer 30 inputting the comparison signal from the comparator 50 detects the accumulated state of the waste toner by examining the logic state of the comparison signal, and then drives the light emitting device LED1 according to the accumulated state of the waste toner. do.
이때 마이콤(30)은 비교신호의 논리상태가 하이논리상태일 경우엔 폐토너통(10)에 폐토너가 만충되었다고 판단하여 하이논리상태의 경보제어 신호를 출력함으로서 발광소자(LED1)를 점등하여 폐토너를 회수하라는 경보를 한다.At this time, when the logic state of the comparison signal is a high logic state, the microcomputer 30 determines that the waste toner is filled in the waste toner box 10, and outputs a high logic alarm control signal to light the light emitting device LED1. Alerts you to recover the waste toner.
그리고 상기 비교신호의 논리상태가 로우논리상태일 경우 마이콤(30)은 폐토너통(10)에 폐토너가 만충되지 않았다고 판단하여 발광소자(LED1)를 소등한다.When the logic state of the comparison signal is the low logic state, the microcomputer 30 determines that the waste toner is not filled in the waste toner box 10 and turns off the light emitting device LED1.
상기 회중 제1전원(15)은 전류통로 형성시 충분한 전류를 폐토너 축적상태를 알릴수 있는 충분한 직류전압 또는 교류전압을 사용하며, 증폭기(40)는 제2전원(16)의 전압 레벨보다 큰 전압레벨을 갖도록 충분한 증폭율로 토너감지 신호를 증폭한다.The first power source 15 for the congregation uses sufficient DC voltage or AC voltage to inform the waste toner accumulated state when the current path is formed, and the amplifier 40 is larger than the voltage level of the second power source 16. The toner detection signal is amplified at a sufficient amplification rate to have a voltage level.
상술한 바와같이 본고안은 폐토너의 축적상태에 따라 전류통로가 형성되는 가를 감지함으로서 폐토너통(10)의 오염이나 금속판의 오염에 무관하게 폐토너의 축적량을 검지하여 경보할 수 있는 이점이 있다.As described above, the present invention detects whether the current path is formed according to the accumulation state of the waste toner, so that the accumulated amount of the waste toner can be detected and alarmed regardless of contamination of the waste toner box 10 or contamination of the metal plate. have.
