Abstract

PURPOSE:To enable printing on both sides of a cut paper to be carried out speedily and efficiently, by providing a cut paper-reversing platen and an other- side printing head mechanism for reversing the cut paper, fed from a platen, face side back and printing on the other side of the cut paper, and a changeover switch for a both-side printing mode. CONSTITUTION:A changeover switch 109 for a both-side printing mode is set for both-side printing, whereby a printer-driving part 102 is controlled by a printer-controlling part 101, and the face side (one side) of a cut paper 201 is printed by a standard platen 108 and a standard head mechanism 104. When printing on the face is finished, the back side (the other side) of the paper 201 is printed by a cut paper-reversing platen 107 and an other-side printing head mechanism 103. Thus, printing on both sides of the cut paper 201 can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device used in a word processor or the like, and more particularly to a printer device that can perform automatic double-sided printing on cut sheets.

[Prior Art] Conventionally, this type of printer device that prints on cut paper has one platen and print head mechanism for printing on cut paper, and the print head is attached to the cut paper wound around the platen. It was printed by a mechanism.

In other words, printing was performed only on one side of the cut sheet.

[Problems to be Solved by the Invention] The conventional printer device described above prints only on one side of the cut sheet, so when attempting to print on both sides of the cut sheet, The disadvantage of this method is that after printing one side of each sheet one by one, it is necessary to manually turn over the slip sheet, which has already been printed on one side of the eaves, and set it in the printer again for printing.

[Means for Solving the Wi Problems] The present invention has been made to solve the above conventional problems.As a means for solving the problems, the printer device of the present invention prints on one side of a cut sheet In a printer device having a platen and a print head mechanism for printing, a platen for reversing a cut sheet sent from the platen and a head mechanism for printing on the other side, and a head mechanism for printing on the other side by reversing the front and back sides of the cut sheet sent from the platen, and double-sided printing. The configuration includes a mode changeover switch.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram of a printer device according to an embodiment of the present invention.

In the figure, 100 is an upper connection line, 101 is a printer control unit, 1
02 is a printer drive unit, 104 is a standard print head mechanism,
106 is a standard head, 108 is a standard platen, and 201 is a cut sheet.

Normally, the printer control unit 101 receives a signal sent from the upper connection line 100 and controls the printer drive unit 102, thereby moving the standard print head mechanism 104 in the lateral direction of the cut sheet 201, and the standard platen 108. By moving , the printing position in the vertical direction is determined, and the standard head 106 prints on one side of the cut sheet 201 in response to a signal from the printer control unit 101 .

This printer device also includes a cut sheet reversing platen 107 for reversing the cut sheet 201 from the standard platen 108, and a cut sheet 201 that has been inverted.
Other side printing head mechanism 1 for printing on the other side of 1
03. 105 is the other side printing head.

Furthermore, in addition to the printing operation described above, by setting the duplex printing mode changeover switch 109 for duplex printing,
The printer drive unit 102 is controlled from the printer control unit 101, and first the front side (one side) of the cut sheet 201 is printed using the standard platen 108 and the standard head mechanism 104. When the front side is printed, the cut sheet is then reversed. By printing on the back side (other side) using the printing platen 107 and the other side printing head mechanism 103, double-sided printing of the cut sheet 201 is made possible.

[Effects of the Invention] As explained above, the printer device of the present invention has a platen and a print head mechanism for printing on one side of a cut sheet, and the printer device has a platen and a print head mechanism for printing on one side of a cut sheet. a platen for reversing a single sheet and a head mechanism for printing on the other side;
Since the configuration is equipped with a switch for duplex printing mode, it is possible to automatically print on both sides of a cut sheet, which was previously possible only by manually replacing each side of the sheet. The effect is that it can be done efficiently in a short period of time.

[Brief explanation of the drawing]

FIG. 1 is a schematic explanatory diagram showing a printer device according to an embodiment of the present invention. 103: Other side printing head mechanism 104: Standard head mechanism 107: Single sheet reversal platen 108: Standard platen 109; Changeover switch 201: Single sheet paper
