JPH02243367A - Color serial printer - Google Patents

Abstract

PURPOSE:To enable printing of documents, etc., including color graphs in a short time by providing a solenoid for pressing a pen against a sheet, a penholder for setting a plurality of pens, a motor for rotating said penholder, and a means for fitting a carrier with one of said pens. CONSTITUTION:A pen 1 is pressed against a platen 5 by a solenoid 2. In said state, SP motor 8 and LF motor 7 are operated so that a line is drawn on a sheet 6 wound around said platen 5. When said pen is replaced with a new one, a carrier 4 moves to a penholder 11 to set a pen 1 on the penholder 11 and thereafter a penholder motor 9 rotates and stops at the position where a desired pen approaches the solenoid 2. Then, the carrier 4 again approaches the penholder 11 to set the pen on said carrier.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a serial printer, and particularly to a dot matrix serial printer capable of graphic mode printing.

[Conventional technology]

Conventionally, this type of serial printer is capable of bidirectional printing when printing normal characters, but has a method of performing unidirectional printing when printing in a graphic mode. Furthermore, since the number of ribbon colors is small in multicolor printers, a method of printing two colors overlappingly is used in order to express many other colors.

[Problem to be solved by the invention]

The above-mentioned conventional serial printer has the disadvantage that it takes a long time to print in the graphic mode.

[Means to solve the problem]

In order to solve the above problem, the color serial printer of the present invention includes a pen located on a carrier, a solenoid for pressing the pen against the paper, and a Ben holder in which a plurality of pens can be set. It has a plurality of pens of different colors, a motor for rotating the pen holder, and a control means having the function of controlling the solenoid pen holder motor.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings.

Referring to FIG. 1, a pen 1 is pressed against a platen 5 by a solenoid 2. In that state, SP motor 8, L
A line is drawn on the paper 6 wrapped around the platen 5 by operating the F momo-7.

When replacing the pen, the carrier 4 moves to the pen holder 11 and sets the pen 1 in the pen holder 11, and then the pen holder motor 9 rotates and stops when the desired pen comes near the solenoid 20. The carrier 4 approaches the pen holder 11 again and places the pen on the carrier.

FIG. 2 is a block diagram showing one embodiment of the present invention. The control means 11 controls the SP motor 12 . LF motor 13, solenoid 14
．． Controls the pen holder motor 15.

〔Effect of the invention〕

As explained above, the present invention enables drawing lines at high speed by pressing the pen on the carrier against the paper and performing spacing and paper feeding operations.Furthermore, since multiple pens can be used, documents including color graphs can be drawn easily. This has the effect that printing such as can be done in a short time.

[Brief explanation of drawings]

FIG. 1 is a top view showing an embodiment of the invention, and FIG. 2 is a block diagram showing an embodiment of the invention.

Claims (1)

[Claims] In a serial printer having a print head for printing characters, a carrier for mounting the print head, a spacing means for moving the carrier, and a paper feeding means for feeding paper, the serial printer is provided replaceably on the carrier. a solenoid for pressing the pen against the paper; a pen holder in which a plurality of pens of different colors are set; a motor for rotating the pen holder; and one of the plurality of pens is attached to the carrier. A color serial printer comprising means.
