본 발명은 금전등록기용 프린터의 고속인자방법에 관한 것이다.The present invention relates to a high speed factor method of a cash register printer.

종래의 금전등록기에 있어서, 제 1 도에서와 같이 활자드럽배열의 활자륜을 가진 프린터의 영수증 인자형태는 예로서 제 2 도에 도시되어 있다.In a conventional cash register, the receipt printing form of a printer having letterpress-shaped type wheels as shown in Fig. 1 is shown in Fig. 2 as an example.

제 2 도와 같이, 영수증에 연속해서 데이터를 인자하고자 할때 금전등록기의 프린터는 제 1 라인을 인자한다음 종이를 이송하고, 다음의 제 2 라인은 리세트 펄스에 의해 프린터의 드럼의 구동이 초기화된 다음에 인자되며, 제 3 라인은 상기 리세트펄스에 의해 드럼의 구동이 초기화된 다음에 인자되기 때문에 드럼의 활자륜이 세번 회전되어 인자속도가 느린 결점이 있었다.As with the second diagram, when printing data continuously on a receipt, the printer of the cash register prints the first line and then conveys the paper, and the next second line resets the driving of the drum of the printer by the reset pulse. Printed next, the third line was faulted because the type wheel of the drum was rotated three times because the printing of the drum was initiated after the drum was initialized by the reset pulse.

따라서, 본 발명의 목적은 상기한 결점을 해결하기 위해, 금전등록기의 프린터의 드럼이 초기화되도록 구동하게 하는 리세트펄스를 중앙처리창치에서 인식한 다음 제 1라인을 인자하고, 문자펄스가 입력될 때마다 카운터값을 증가시키면서 종이의 이송동작을 수행하며, 이 카운터값과 제 2 라인에 프린트해야할 테이터를 비교하여 일치할때 제 2 라인의 테이터를 인자하고, 제 2 라인의 프린트방식과 동일하게 제 3 라인의 데이터를인자하여 드럼의 활자륜이 1회전만 회전되어도 3라인분의 데이터를 인자할 수 있는 고속인자방식을 제공하는데 있다.Accordingly, an object of the present invention is to recognize a reset pulse at the central processing window to drive the drum of the printer of the cash register so that the drum of the printer of the cash register is initialized, and then print the first line, and the character pulse can be input. Whenever the counter value is increased, the paper transfer operation is carried out. The counter value is compared with the data to be printed on the second line, and when the data is matched, the second line data is printed, and the printing method of the second line is the same. It is to provide a high-speed factor method that can print the data for the three lines even if the type wheel of the drum is rotated only one rotation by the data of the third line.

다음은 첨부도면에 의거하여 본 발명의 실시예를 상세히 설명한다.Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 3 도는 본 발명에 따른 프린터의 고속인자방법을 적용한 금전등록기의 기능별 블록도로서, 중앙처리창치(1)는 제반장치를 제어하고, 롬(4)는 제어수단인 프로그램이 내장되어 있으며, 램(5)에는 시스템 처리과정에서 필요한 데이터가 보존되고, 키보드(6)는 사용자의 키입력을 인식하며, 부저(7)는 사용자의 키입력과 에러상태를 알려주고, 서랍장치(8)는 거래상 종료되었을때 열리게 되고 아울러 현금을 보관하고, 전원부(9)는 시스템 전체에 전원을 공급하며 정전시에는 배터리 백업(Back Up)장치에 의해 전원을 공급하여 시스템 처리중 발생되는 제반데이터를 메모리에 저장할 수 있도록 하며, 디스플레이(3)는 사용자에게 거래상태를 표시하고, 프린터(2)는 거래된 결과의 영수증을 발행하는 장치이다.3 is a functional block diagram of a cash register to which a high speed factor method of a printer according to the present invention is applied. The central processing unit 1 controls various devices, and the ROM 4 includes a program as a control unit. In (5), data necessary for system processing is preserved, the keyboard (6) recognizes the user's key input, the buzzer (7) informs the user of the key input and error state, and the drawer device (8) is on the transaction. It is opened when it is finished and also stores cash. The power supply unit 9 supplies power to the entire system. In case of power failure, the power supply is supplied by a battery backup device to store all data generated during system processing in a memory. The display 3 displays a transaction state to the user, and the printer 2 is a device for issuing a receipt of the transaction result.

상기 중앙처리장치(1)와 프린터(2)사이에는, 중앙처리장치에서 프린터(2)의 드럼구동용 모터를 제어하는 신호를 제공하는 라인과, 중앙처리장치가 프린터 드럼의 활자륜의 초기치를 인식하게 하는 리세트 펄스를 입력하는 라인과, 중앙처리장치가 활자륜의 현재상태를 알려주는 문자펄스를 입력하는 라인 및 프린터의 종이이송, 리본이송, 인자를 위한 솔레노이드의 구동, 햄머구동을 위한 솔레노이드구동을 제어하기 위한 라인들이 접속되어 있다.Between the central processing unit 1 and the printer 2, a line for providing a signal for controlling the drum driving motor of the printer 2 in the central processing unit, and the central processing unit having an initial value of the type wheel of the printer drum. Line for inputting reset pulse for recognition, Line for inputting pulse for the central processing unit indicating the current state of the wheel, Paper feed, ribbon feed, Solenoid drive for printing, Hammer drive for Lines for controlling solenoid drive are connected.

먼저, 금전등록기의 영수증 발행시 점검 혹은 정산과 같은 경우 또는 사용자가 키입력을 빨리하는 경우 제 2 도와 같이 영수증에 몇개라인의 데이터를 연속해서 프린트해야하는 경우가 많은데, 이를 본 발명에 따른 고속인자방법의 처리순서도인 제 4 도에 의거하여 설명한다.First, in case of checking or settlement of a receipt of a cash register, or when a user inputs a key quickly, there are many cases in which several lines of data must be continuously printed on the receipt as in the second method, which is a fast factor method according to the present invention. A description will be given based on FIG. 4 which is a flowchart of the processing.

롬(4)에 저장된 시스템제어수단인 매인프로그램내에서 프린트의 부프로그램으로 중앙처리장치(1)의 실행이 옮겨가면, 중앙처리장치(1)에서는 모터구동을 온시키는 제어신호를 프린터(2)로 제공된다.When the execution of the central processing unit 1 is transferred to the subprogram of the print in the main program which is the system control means stored in the ROM 4, the central processing unit 1 outputs a control signal for turning on the motor drive to the printer 2; Is provided.

이때부터 모터가 회전되면서 리세트펄스가 발생되는데, 이때에 중앙처리장치는 문자펄스카운터를 클리어시킨 다음 문자펄스가 인터럽트단자 INT1에 인가되기까지 기다리다가 첫번째 문자펄스가 입력되면 마지막 문자펄스인지를 비교한다.At this time, the motor rotates to generate reset pulse. At this time, the CPU clears the character pulse counter and waits for the character pulse to be applied to the interrupt terminal INT1. do.

상기 문자펄스 카운터는 메모리인 램의 특정번지를 이용하여 중앙처리장치에 의해 카운트 동작된다.The character pulse counter is counted by the CPU using a specific address of RAM, which is a memory.

만일, 첫번째 문자펄스가 입력되면 문자펄스 카운터와 프린트메모리의 내용이 모두 "0"이기 때문에 중앙처리장치는 프린터의 드럼을 구동하는 해당 포트를 온시킨다.If the first character pulse is input, since the contents of the character pulse counter and the print memory are all "0", the central processing unit turns on the corresponding port for driving the drum of the printer.

즉, 제 2 도의 제 1 라인에서는 포트 0-포트 11까지가 온되어 12칼럼(Column)을 모두 인자했기 때문에 프린터는 중앙처리장치에 1라인의 종이이송을 한 다음 문자펄스 카운터의 값을 1증가 시킨다.In other words, in the first line of FIG. 2, since ports 0 through 11 are turned on to print all 12 columns, the printer transfers one line of paper to the central processing unit, and then increases the value of the character pulse counter by one. Let's do it.

다시 중앙처리장치는 문자펄스의 입력을 기다리는데, 예를들어 문자펄스가 5번 입력되었다면 중앙처리장치의 문자펄스 카운터의 데이터는 5가 되고, 제 2 도의 제 2 라인을 인자하기 위하여 제 6 도에 도시한 프린트 메모리에는 5가 저장되어 있으므로 각 포트를 이에 따른 포트를 온시킨다.Again, the CPU waits for input of the character pulse. For example, if the character pulse has been input five times, the data of the character pulse counter of the CPU becomes 5, and in order to print the second line of FIG. Since 5 is stored in the illustrated print memory, each port is turned on accordingly.

이렇게 하여, 제 2 라인을 인자하고 그리고 1라인의 종이이송을 한 다음 계속해서 연속인자를 한다.In this way, the second line is printed and one line of paper is transferred, followed by the continuous factor.

결국, 한 라인을 인자하고 종이 이송을 한 다음 연속 프린트요구 플랙이 세트되어 있으면, 모터를 오프시키지 않은 상태에서 문자펄스가 입력될때마다 문자펄스카운터의 데이터는 1식 증가시켜 프린트메모리의 내용과 비교한다.Eventually, if one line is printed, the paper is transferred, and the continuous print request flag is set, the character pulse counter data is increased by one expression each time the character pulse is input without turning off the motor, and compared with the contents of the print memory. do.

상기의 문자펄스 카운터와 프린트 메모리의 테이터가 일치할때 중앙처리창치는 해당되는 포트를 온시켜서 대응되는 데이터를 인자한다.When the character pulse counter and the data of the print memory match, the central processing window turns on the corresponding port and prints the corresponding data.

이상에서 설명한 바와같이, 본 발명에 의한 금전등록기를 종래의 금전등록기의 프린터보다 데이터의 인자속도를 배가시킨 이점이 있다.As described above, there is an advantage that the cash register according to the present invention doubles the printing speed of data than the printer of the conventional cash register.
