Abstract

PURPOSE:To enable to perform lateral writing in a transverse direction and a longitudinal direction and to draw figures, by providing two printing solenoids orthogonally to each other so that a plotter pen can be moved upward and downward, in a disk rotating type printing plate printer. CONSTITUTION:In accordance with a printing or drawing command, pulse motors 1, 11 and 15 are rotated to select a printing position and a type position of a daisy wheel 16, and either of the solenoids 17, 18 provided orthogonally to each other is driven, whereby lateral writing printing in the transverse direction or lateral writing printing in the longitudinal direction is conducted. In addition, by operating a pen solenoid 20, a straight line or a quadric curve can be drawn on the basis of classification of solid line, dotted line, broken line, dot- dash line or the like. Further, by replacing the daisy wheel 16, the kind and the size of characters can be arbitrarily selected. Accordindly, a printer-plotter small in size and weight and capable of printing clearly can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer-plotter having a rotating disc type printing plate (hereinafter referred to as a "Dage"), and particularly relates to a printer-plotter that is capable of creating charts, horizontal printing in the horizontal direction, and horizontal printing in the vertical direction. .

Conventionally, XY plotters have been mainly used as charting machines, but in this type of plotter, the plotter head itself moves in the X and Y directions, so the printing paper must be placed horizontally, which reduces the flat surface area. It has the disadvantage of becoming large and requiring a large space, and also has the disadvantage of being difficult to move.

Diagrams inevitably require explanatory characters, but since lines are drawn with an ink pen in the XY plotter's drawing mechanism, when writing characters, a jagged appearance due to the input step appears in the font, and the shape of the font also changes. There were drawbacks such as the font being unclear due to restrictions in the X and Y directions, and the font being unique and difficult to read. These shortcomings were especially noticeable in small fonts. Furthermore, there was still a major drawback in that the printing speed was extremely slow when writing characters.

Recently, small XY plotters have been developed, but these also have problems, especially in terms of print quality.

The present invention has been made in view of the above-mentioned facts, and it is an object of the present invention to provide a printer-plotter that can create charts and print clear horizontal and vertical writing using printed characters.

The present invention provides a rotary disk type printing plate printer with a plotter pen that is movable in the vertical direction, and two printing solenoids that are placed in positions facing each other at right angles. The printing solenoids are respectively responsible for horizontal horizontal printing and vertical horizontal printing, so that charts can be created and explanatory characters can be printed vertically and horizontally.

Embodiments of the printer plotter according to the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, in which the rotation of a platen pulse motor 1 is transmitted to an X-side platen 4 via timing gears 2, 2' and a timing belt 6. This rotation simultaneously rotates the X-side platen 7 via the timing gears 5, 5' and the timing belt 6. This rotation is transmitted by a sprocket 8 provided on the outer periphery of each platen 4 and 7 through sprocket holes 10 formed on both sides of the printing paper 9 to cause the printing paper 9 to move back and forth in the Y arrow direction. The printing position on the printing paper 9 in the Y direction is selected based on the command.

Further, the rotation of the carriage pulse motor 11 is controlled via the timing gears 12, 12' and the timing belt 16, and the carriage 1, which is fixedly attached to the timing belt 16, is rotated by the carriage pulse motor 11.
4, and the printing position in the X direction is selected based on the print command.

The digitizing pulse motor 15 fixed to the carriage 14 rotates in response to a type position command, and the digitizing pulse motor 15 rotates the digitizing 16 fixed to the rotating shaft to select the type position. It's becoming like this.

In addition, an X-side printing solenoid 17 and a Y-side printing solenoid 18 are fixedly installed on the outer casing 14 of the motor 15.
As shown in FIG. 6, the X-side printing solenoid 17 is arranged at the vertical centerline position of the dage 16, and the Y-side printing solenoid 18 is arranged at the horizontal centerline position offset by 900 degrees counterclockwise. Furthermore, the center distance between the X-side platen 4 and the X-side platen 7 is determined by the inner printing solenoid 1 as shown in FIG.
The mounting centers of plates 7 and 18 are arranged to coincide with the centers of both platens 4 and 7, respectively. Therefore, the X-side printing solenoid 17 is in charge of printing characters in the vertical position of the page 16, that is, printing in the X direction, and as the carriage 14 moves in the X direction, horizontal printing is performed in the horizontal direction. Similarly, the Y-side printing solenoid 18 is in charge of horizontal position printing of the page 16, that is, printing in the Y direction,
As the Rif marking printing paper 9 moves in the Y direction, vertical and horizontal printing is performed.

Further, a metal fitting 19 is fixed to the carriage 14, and a pen solenoid 20 is supported on this metal fitting 19.

This pen solenoid 2o is excited by a drawing command,
Ink pen 21 integrated with this pen solenoid 20
It is designed to move up and down. The tip of this ink pen 21 contacts the surface of the printing paper 9 on the platen 4 toward the center line of the platen 4 in the X direction, and in response to a drawing command, moves the paper 9 in the Y arrow direction and moves the carriage 14. By combining the movements in the direction of the X arrow, a straight line or a quadratic curve is drawn on the printing paper 9.

A ribbon cassette 22 is placed and fixed on the carriage 14, and the ribbon 2M stored in the ribbon cassette 22 is tilted at 900 degrees or any arbitrary angle to cover the printing width on the XY side. , Y are staggered so that the peeling of the ribbon ink caused by the stamping of each print does not overlap. 24 is a paper holding roller.

With the printer plotter according to the embodiment of the present invention configured as described above, the pulse motors 1, 11, and 15 rotate in response to a printing or drawing command to select the print position and the character position of the page 16, The solenoid 17 or 18 performs horizontal horizontal printing or vertical horizontal printing, respectively, and the pen solenoid 20 operates to draw a straight line or a quadratic curve. The type of straight line or quadratic curve described above can be classified into straight lines, dotted lines, broken lines, and chain lines depending on the drawing command. It is also possible to select the type and size of the font by exchanging the digits.

As a result of the above, a chart as shown in FIG. 2 can be created.

According to the present invention, printing quality is improved even though type is used for printing, and the price can be made as low as that of a typewriter. Furthermore, the overall shape is small, making it easy to carry and move.

In this embodiment, only one ink pen 21 is used, but by using a turret type ink pen holding device, it is possible to differentiate by color and wire diameter. As for the method of moving the carriage 14, in this embodiment the timing belt 16 is used, but means such as wire drive and screw feeding may also be used.

Furthermore, the paper 9 can also be a cut paper instead of a continuous paper with sprocket holes. Furthermore, it goes without saying that the present invention can also be applied to a flat plotter.

As described above, the present invention provides a rotary disk type printing plate printer in which the plotter pen is provided so as to be movable up and down, and the two printing solenoids are provided at mutually perpendicular positions. The effect of being able to provide a small, lightweight, and low-cost printer/plotter that can print horizontally in the horizontal direction, horizontally in the vertical direction, and plot straight lines or quadratic curves, and that can also print clearly with type is very effective. .
