Abstract

PURPOSE:To eliminate troublesome operation of setting page ends by a method in which the number of printable lines of a paper is stored in a lead-on memory in advance, and paper feeding operation is made to the end of a paper before printing is made by user. CONSTITUTION:When power source is turned on, an arithmetical control circuit 2 is reset, and a printer 5 is induced through a drive circuit 6 to a printable waiting state by the arithmetical control circuit 2 on the basis of detection signals relevant to the position information of the printer. In the circuit 2, country- classified code signals are read out by the circuit 3 in which country-classified information incorporated in the keyboard 1 is codified, and on the basis of country-classified codified signals, data on printable line number to be obtained from the kinds of country-classified key switches and the sizes of paper are read out from an ROM7 storing the data as units in the circuit 3. In the detection signal conversion circuit 4, the numerical data of printable line number are held in a register in the arithmetical control circuit 2. When printing is made and the end of paper is reached according to the input to key by user, printing beyond the number of printable lines stored is automatically prohibited.

Since the types are different, a circuit 6 that encodes country-specific information is built into the keyboard section 1, and a country-specific code signal is input to the arithmetic control circuit 2 via a line 12. The arithmetic control circuit 2 includes a read-only memory that converts and stores microinstruction information for sequential control into digital signals, converts the information, and discriminates the information, an arithmetic unit that performs arithmetic processing according to information from the read-only memory, and numerical data. It consists of a group of registers that hold the data, an adder for executing the performance, and a control section for performing other controls. 4 is a conversion circuit for the detection signal obtained from the printer 5, which converts the signal so that various information from the printer 5 can be processed by the arithmetic control circuit 2; It is output to. 6 is a drive circuit for the printer 5, which connects the line e4 from the arithmetic control circuit 2.

Next, the operation of the auto page end according to the present invention will be explained according to the flowchart shown in FIG. 2. When the electronic typewriter is powered on, the arithmetic control circuit is reset in step 1, and based on a detection signal related to the printer's position information, the arithmetic control circuit guides the printer to a printable standby state via the drive circuit. . 2, from the circuit that encodes country-specific information built into the keyboard section,
The arithmetic control circuit reads the country-specific code signal, and in step 3, based on the country-specific code signal, data regarding the number of printable lines required from the key switch type and paper size for each country is stored for each country. The numerical data of the number of printable lines (4) is stored in a register in the arithmetic control circuit. Steps 2, 3, and 4 are included in the reset operation of the entire typewriter system, and may be performed before or after the order of operations in step 1. When the resetting operation of the typewriter is completed in this way, the user feeds the paper in step 5 and becomes ready to print.

8 is a judgment instruction for determining whether or not to execute a line feed when a line feed command is input. This judgment is determined from the number of lines that have been line fed since paper feeding in 5 and the size of the standard paper for each country, and the arithmetic control circuit This is done by comparing the number of printable lines held in a register within the line. If the number of line feeds is less than the number of printable lines, the Stella 190 performs a normal paper feed operation to feed a line feed, and returns to the printable state in step B. If the number of lines with reverse pressure line breaks is greater than or equal to the number of printable lines, it is assumed that the printing capacity of the paper has been exceeded, and in step 10 a page end warning is output using a buzzer, display, etc., and printing is stopped. .

As described above, in the present invention, the number of printable lines of the paper is stored in the read-only memory in advance, so before the user prints, the user performs the paper feed operation to the end of the paper, and the end of the page is reached seven times. This eliminates the complexity. In addition, changes in the number of printable lines caused by different paper standard sizes in each country can be selected appropriately for each country from read-only memory using country code signals, making it more automated and superior to the conventional auto page end function. An electronic typewriter can be realized.
