Abstract

PURPOSE:To simultaneously print both surfaces of paper by a method wherein a printing mechanism part having a front printing head part and a rear printing head is provided and the printing data inputted from an external apparatus is divided by one page to be sent out to both printing head parts. CONSTITUTION:The printing data inputted from an external apparatus is distributed by one page by the interface part 1 with the external apparatus so that the printing data of the first page is set to front printing data and that of the second page is set to rear printing data and sent out to a memory part 2 to store the data of two pages in a front printing data memory part 3 and a rear printing data memory part 4 at once. The stored front and rear printing data are successively sent out to the front printing head part 6 and the rear printing head part 7 of a printing mechanism part 5 at the same time. The front and rear printing head parts 6, 7 are cooperated in the direction shown by an arrow and moves on a guide rail 8 to print both surfaces of the printing paper 10 held between both printing heads according to sent printing data. The paper is taken up by a printed paper take-up roller 9 to finish the printing of two pages.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a simple printer.

[Conventional technology]

Conventional simple printers use a single-sided printing head unit to sequentially print one page at a time on only one side of a sheet of paper.

[Problem to be solved by the invention]

Conventional simple printers have a single-sided print head and are designed to print only on one side of the paper, so in order to print one page each on the front and back sides of the paper in order, This method has the disadvantage that it is necessary to manually feed the paper for each page and switch the front and back sides, and that it automatically separates the paper into both sides and cannot print at the same time.

[Means to solve the problem]

The simple printer of the present invention includes an interface unit with an external device and a memory unit for distributing print information read from an external device into front side and back side and sending it to the print head unit, and a memory unit for printing the print information. It has a printing mechanism section having a front side print head section and a back side print head section.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of the configuration of an embodiment of the present invention, FIG. 2 is a fixed top view of the printing mechanism, and FIG. 3 is a sectional view of the printing mechanism.

An example of the present invention is shown below.

The printing information input from the external device is distributed to each page by the interface unit 1 with the external device, with the printing information of the first page as the front side printing information and the printing information of the second page as the back side printing information, Sends to memory section 2, front side print information in memory section 2 memory section 3
The information is stored in the backside print information memory section 4 for two pages at a time.

The front side print information and the back side print information stored in the memory section 2 are simultaneously sent out sequentially to the front side print head section 6 and the back side print head section 7 of the printing machine and the structure section 5. Front print head section 6. The backside print head section 7 moves in the direction of the arrow and prints on both sides of the paper 10 sandwiched between both print heads while moving on the guide rail 8 in accordance with the sent print information.

The paper is rolled up by the printing paper winding roller 9, and when printing for two pages is completed, the printing information for the next two pages is input, and printing is repeated on both sides simultaneously in the same manner.

〔Effect of the invention〕

As explained above, the present invention has a printing mechanism section having a front side print head section and a back side print head section, and print information inputted from an external device is divided into one page each, and the two print heads This has the effect of printing on both sides of the paper at the same time.

Claims (1)

[Claims] A printing mechanism unit has a front side print head unit that prints on the front side of the paper, and a back side print head unit that prints on the back side of the paper, and print information to the front side print head and the back side print head is distributed to the front side portion and the back side portion. A simple device characterized in that it has an interface section with an external device for sending out, and a memory section that stores print information distributed by this interface section, and prints one page at a time on both sides of the paper at the same time. printer.
