이중 헤드 구조를 가진 잉크젯 프린터의 병렬 구동 장치 및 방법Parallel driving device and method of inkjet printer with dual head structure

본 발명은 이중헤드 구조를 가진 잉크젯프린터에 관한 것으로, 보다 상세하게는 이중헤드를 활용하여 여러 가지 모드로 인쇄할 수 있도록 구성된 병렬 구동장치 및 병렬 구동 방법에 관한 것이다.The present invention relates to an inkjet printer having a double head structure, and more particularly, to a parallel driving device and a parallel driving method configured to print in various modes using a double head.

종래의 잉크젯프린터는 이중헤드를 장착하는 경우, 모노와 칼라를 구분하고 있다.Conventional inkjet printers distinguish between mono and color when a double head is mounted.

모노 인쇄시 모노헤드만을 이용하고, 칼라 인쇄시에는 칼라헤드만을 이용하는 방법으로 위치가 고정되어 있다. 또한 모노와 칼라가 나란히 쌍을 이루도록 구성되어 있다.The position is fixed by using only a mono head for mono printing and only a color head for color printing. It is also configured to pair mono and collar side by side.

또한 이중헤드를 사용할 때 장착 헤드의 위치를 반드시 지켜야 되었다. 즉 모노 자리에는 모노용 카트리지만을, 칼라 자리에는 칼라용 카트리지만을 사용하여야 했다.In addition, the position of the mounting head must be observed when using the double head. In other words, only the mono cartridge and the color cartridge should be used for the mono seat.

따라서 모노 또는 칼라만을 이중으로 프린팅할 수 없었다.Thus mono or color alone could not be printed in duplicate.

본 발명은 이러한 문제점을 해결하기 위한 것으로서, 이중헤드의 장착시 사용자가 임의로 제 1 헤드 및 제 2 헤드를 모노 또는 칼라로 설정할 수 있도록 하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object thereof is to allow a user to arbitrarily set the first head and the second head to a mono or a collar when the double head is mounted.

본 발명의 다른 목적은 사용자가 제 1 헤드 및 제 2 헤드를 동일하게 선택한 경우 2 행인쇄를 실행할 수 있도록 헤드의 배치 구조를 변경하여 사용자가 여러모드로 사용할 수 있도록 함에 있다.Another object of the present invention is to change the arrangement of the heads so that the user can use them in various modes so as to execute two-row printing when the user selects the first head and the second head identically.

본 발명의 또다른 목적은 이중헤드를 사용하므로써 동시에 2 라인을 인쇄하여 인쇄속도를 향상시키는 데에 있다.Another object of the present invention is to improve printing speed by printing two lines at the same time by using a double head.

And a switching means for sensing the size of the pulse and switching means for switching the response pulse to generate a set mode signal for each head to the CPU.

또한 이러한 병렬구동장치를 이용한 병렬 구동방법의 특징은 헤드 체크를 위해 제 1 헤드 및 제 2 헤드의 모드를 체크하는 과정과, 체크된 헤드의 모드를 모노 및 칼라로 등록하는 과정과, 프린터의 수행에 따라 각 헤드의 현재 설정 모드에 따라 모두 칼라인 경우에 칼라로만 동시에 1 라인씩 프린팅하는 과정과, 프린터의 수행에 따라 각 헤드의 현재 설정 모드에 따라 모두 모노인 경우에 모노로만 동시에 1 라인씩 프린팅하는 과정과, 프린터의 수행에 따라 각 헤드의 현재 설정 모드에 따라 모노와 칼라가 혼용된 경우에 각 헤드의 모드에 맞게 모노 혹은 칼라로 동시에 1 라인씩 프린팅하는 과정을 포함하는 점에 있다.In addition, the parallel driving method using the parallel drive device is characterized in that the first head and the second head mode of checking the mode for the head check, the registered mode of the checked head in mono and color, and performing the printer According to the current setting mode of each head, the process of printing one line at a time only in color only, and only one line at the same time only in mono when all heads are mono according to the current setting mode of each head according to the performance of the printer.

도 1은 본 발명에 따른 이중헤드 구조를 가진 프린터의 병렬구동장치를 나타내는 회로도이다.1 is a circuit diagram showing a parallel drive device of a printer having a double head structure according to the present invention.

도시된 바와 같이 CPU(10)의 제어신호를 전달하는 헤드 드라이버(11,12)와, 상기 헤드 드라이버(11,12)에 각각 연결되고, 그 제어신호에 따라 프린트를 수행하는 헤드(21,22)와, 상기 헤드(21,22)에 에노드단이 연결되고, 케소드단에 전원을 공급받아 전달하는 풀-업 저항(R1,R2)이 연결되도록 구성된 다이오드(D1,D2)와 상기 다이오드(D1,D2)의 케소드단과 저항(R1,R2)의 연결점에 접속되어, 인가되는 전압과 기준 전압의 크기여부에 따라 턴-온 여부가 결정되는 제너다이오드(ZD1,ZD2)와, 상기 제너다이오드(ZD1,ZD2)의 전달신호를 각 베이스단에 받고 그 콜렉터단에 풀-업저항(R3,R4)를 통해 VCC전압을 인가받아 스위칭되어 콜렉터단으로 상기 CPU(10)에 스위칭결과를 전달하는 트랜지스터(Q1,Q2)로 구성된다.As shown, the head drivers 11 and 12 which transmit control signals of the CPU 10 and the head drivers 11 and 12 which are connected to the head drivers 11 and 12, respectively, and which perform printing according to the control signals are provided. And a diode (D1, D2) configured to be connected to the head (21, 22), an anode end, and a pull-up resistor (R1, R2) for receiving and transmitting power to the cathode end. Zener diodes ZD1 and ZD2 connected to the cathode terminals of the resistors D1 and D2 and the resistors R1 and R2 and turned on depending on the magnitude of the applied voltage and the reference voltage, and the zener The transfer signals of the diodes ZD1 and ZD2 are received at each base end, and the collector end is applied with the V CC voltage through the pull-up resistors R3 and R4 to be switched to provide the switching result to the CPU 10 at the collector end. It consists of transistors Q1 and Q2 to transfer.

이러한 구성을 갖는 병렬 구동장치는 제 1 헤드(21) 및 제 2 헤드(22)에 장착되는 카트리지가 모노카트리지 인지 혹은 칼라카트리지인지를 구분할 수 있도록 장착된 카트리지가 모노인 경우에만 응답 펄스가 공급되는 회로로 구성된다.The parallel drive device having such a configuration is provided that the response pulse is supplied only when the cartridge mounted to be mono to distinguish whether the cartridge mounted on the first head 21 and the second head 22 is a mono cartridge or a color cartridge. It consists of a circuit.

제 1 헤드(21) 및 제 2 헤드(22)에 카트리지가 장착되면 헤드 체크 펄스가 각각 드라이버(11,12)를 통해 인가된다. 헤드 드라이버(11,12)는 응답펄스를 발생하고 이에 따라 다이오드(D1,D2)가 도통된다.When the cartridges are mounted in the first head 21 and the second head 22, the head check pulses are applied through the drivers 11 and 12, respectively. The head drivers 11 and 12 generate response pulses, so that the diodes D1 and D2 conduct.

상기 다이오드(D1,D2)는 응답 펄스를 후단에 전달하는 역할을 한다. 전달된 응답펄스의 전압레벨이 일정전압 이하이면 제너다이오드(ZD1,ZD2)가 오프된다. 상기 제너다이오드(ZD1,ZD2)가 오프되면 스위칭 트랜지스터(Q1,Q2)는 턴-오프된다. 따라서 응답펄스는 하이를 발생하게 된다.The diodes D1 and D2 serve to transmit a response pulse to the rear end. Zener diodes ZD1 and ZD2 are turned off when the voltage level of the transmitted response pulse is lower than or equal to a predetermined voltage. When the zener diodes ZD1 and ZD2 are turned off, the switching transistors Q1 and Q2 are turned off. Therefore, the response pulse is generated high.

보통, 모노 헤드의 노즐은 N0∼N56으로 구성되며, 칼라 헤드의 노즐의 수는 N0∼N48으로 구성된다. 다시 말해서 모노 헤드 노즐의 수가 칼라 헤드의 노즐의 수보다 많다.Usually, the nozzle of the head is composed of mono-N 0 ~N 56, the number of nozzles of the color head is of a 48 N 0 ~N. In other words, the number of mono head nozzles is larger than the number of nozzles of the color head.

따라서 CPU(10)에서 노즐 N50에 체크 펄스를 보냈을 때 응답펄스가 발생하면 모노 카트리지가 장착되어 있음을 인식할 수 있으며, 응답펄스가 전달되지 않으면 칼라 카트리지가 장착되거나, 카트리지가 장착되지 않은 것으로 간주할 수 있다.Therefore, when a response pulse occurs when the CPU 10 sends a check pulse to the nozzle N 50 , it can be recognized that a mono cartridge is installed.If no response pulse is transmitted, a color cartridge is installed or a cartridge is not installed. Can be regarded as.

이 때 노즐 N0에 체크 펄스를 가하여 응답이 있다면 칼라 카트리지가 장착되었으며, 응답이 없다면 아무 카트리지도 장착되어 있지 않다는 것을 인식할 수 있다.At this time, it is possible to recognize that if there is a response by applying a check pulse to the nozzle N 0 , a color cartridge is installed, and if there is no response, no cartridge is installed.

이러한 방법은 각 헤드에 동일하게 적용되며, 각 헤드에 장착된 카트리지의 모노 혹은 칼라의 모드를 설정상태를 인식할 수 있게 된다.This method is equally applied to each head, and it is possible to recognize the setting state of the mono or color mode of the cartridge mounted on each head.

이와 같이 각 헤드의 모드가 설정된 상태를 이용하여 병렬구동하는 방법에 대하여 도 2를 참조로 설명한다.As described above, a method of parallel driving using the state in which the mode of each head is set will be described with reference to FIG. 2.

상술한 바와 같이 제 1 헤드 및 제 2 헤드의 설정상태를 인식하여 소정의 메모리에 등록한다(S1 과정).As described above, the setting state of the first head and the second head is recognized and registered in the predetermined memory (step S1).

각 헤드의 모드가 설정된 상태에서 프린팅 명령을 전달받으면(S2 과정), 각 헤드의 현재 설정 모드를 읽어 들인다.(S3 과정)If a printing command is received while the mode of each head is set (step S2), the current setting mode of each head is read (step S3).

두 헤드가 모두 칼라인가를 확인하여(S4 과정), 둘 다 칼라 카트리지이면 칼라모드로 각 1 라인씩을 인쇄한다(S5 과정 ).Check that both heads are color (step S4), and if they are both color cartridges, print each line in color mode (step S5).

두 헤드가 모두 모노인가를 확인하여(S6 과정), 둘 다 모노 카트리지이면 모노모드로 각 1 라인씩을 인쇄한다(S7 과정 ).Check that both heads are mono (step S6), and if both cartridges are mono print each line in mono mode (step S7).

두 헤드가 동일 모드가 아닌 경우에는 제 1 헤드가 모노인가를 확인하여(S8 과정), 모노인 경우 제 1 헤드는 모노모드로, 제 2 헤드는 칼라모드로 인쇄한다(S9 과정).If the two heads are not the same mode, it is checked whether the first head is mono (step S8), and if it is mono, the first head is printed in mono mode and the second head is printed in color mode (step S9).

상기 S8 과정에서의 결과가 모노가 아닌 경우에는 제 1 헤드는 칼라모드로, 제 2 헤드는 모노모드로 인쇄한다(S10 과정).If the result of the step S8 is not mono, the first head is printed in the color mode and the second head is printed in the mono mode (step S10).

이러한 과정은 프린팅 종료의 신호가 확인될 때까지 진행된다(S11 과정) .This process is performed until the signal of the end of printing is confirmed (S11 process).

여기에서 상기 S1 과정은 도 3에 나타난 바와 같이 이루어진다.Here, the S1 process is performed as shown in FIG. 3.

헤드의 50 번 노즐에 체크펄스를 인가하여(S1-1 과정) 응답펄스가 있으면 모노 모드로 설정한다(S1-2 과정).A check pulse is applied to nozzle No. 50 of the head (step S1-1), and if there is a response pulse, it is set to mono mode (step S1-2).

이 때 응답이 없으면 헤드의 0번 노즐에 체크펄스를 인가한다(S1-3 과정).At this time, if there is no response, a check pulse is applied to nozzle 0 of the head (step S1-3).

이 때에도 응답이 없으면 카트리지가 장착되지 않았다는 것을 인식한다(S1-4 과정).If there is no response at this time, it is recognized that the cartridge is not installed (step S1-4).

만일 응답이 있다면 칼라 카트리지가 장착되어 있으며 이에 따라 해당 헤드를 칼라 모드로 등록하게 된다(S1-5 과정).If there is a response, a color cartridge is installed and the corresponding head is registered in the color mode (step S1-5).

이러한 각 헤드의 모드 인식과정은 두 헤드에 동일하게 적용된다.The mode recognition process of each head is equally applied to the two heads.

위와 같이 병렬구동되기 위해서는 두 헤드의 구조가 도 4에 나타난 바와 같이 구성되어야 한다.In order to be driven in parallel as above, the two heads must be configured as shown in FIG. 4.

도 4A는 종래의 이중헤드의 배치구조도이고, 도 4B는 본 발명에 따른 이중헤드의 배치구조도이다.4A is a layout diagram of a conventional double head, and FIG. 4B is a layout diagram of a double head according to the present invention.

도시된 바와 같이 본 발명에 의한 헤드의 배치는 종래기술에 따른 헤드의 배치와 달리, 둘중 어느 하나가 다른 하나의 길이만큼 용지와의 접촉면에 대해 아래쪽에 위치하도록 구성됨을 알 수 있다.As shown, it can be seen that the arrangement of the head according to the present invention, unlike the arrangement of the head according to the prior art, is configured such that either one is positioned downward with respect to the contact surface with the paper by the length of the other.

이러한 배치 구성에 따라 2 라인을 동시에 인쇄할 수 있는 것이다.According to this arrangement, two lines can be printed at the same time.
