Abstract

PURPOSE:To eliminate processing effected in a printer and to shorten a printing time by displaying the screen of a personal computer directly on a liquid crystal panel. CONSTITUTION:A printer device comprises a copying function part 1 to control a copying function, a display control part 2 to control copying display, a connector 4 connected to a personal computer 3 installed to the outside, and a switch 5 connected to a power source. It is further provided with a liquid crystal panel 7 mounted on a copying stand 6 and brought into an achromatic clear state during non-voltage, a cover 8 rotatably mounted in a manner to cover the liquid crystal panel 7, and a white panel 9 mounted on the liquid crystal 7 side of the cover 8. The sheet placing glass surface of a copier utilizing the liquid crystal panel 7 and the copier is replaced with the liquid crystal panel 7, and in this place, screen display is effected by means of a personal computer 3, and by effecting copying, printing is performed. This constitution provides a function as a printer and a function as copying, eliminates processing effected in the printer, and shortens a printing time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer device used in a personal computer or the like.

[0002]

2. Description of the Related Art A conventional page printer takes a long time to print because it processes fonts and the like in the printer according to an output signal from a computer.

[0003]

Since a conventional page printer takes a long time to print and is inconvenient, a liquid crystal panel is used for the copying machine to solve this problem and at the same time, a printer apparatus which can be used as both a printer and a copying machine. I will provide a.

[0004]

According to the present invention, a copy function section for controlling a copy function, a display control section for controlling a copy display, a connector for connecting to an electronic apparatus installed outside, and a power source are connected. A switch, a liquid crystal panel that is placed on a copying table and is in a colorless and transparent state when no voltage is applied, a cover that is rotatably attached to cover the liquid crystal panel, and a white plate that is attached to the liquid crystal panel side of the cover. And a printer device.

[0005]

[Function] A liquid crystal panel and a copy machine are used. The glass surface of the paper holder of the copy machine is replaced with the liquid crystal panel, the screen is displayed by a personal computer or the like, and a copy is made for printing.

[0006]

EXAMPLE An example of the present invention will be described below. FIG. 1 shows a copy function unit 1 for controlling a copy function, a display control unit 2 for controlling a copy display, a connector 4 for connecting to an externally installed personal computer 3, a switch 5 for connecting to a power source, and a copying table 6. A liquid crystal panel 7 which is placed in a transparent state when no voltage is applied, a cover 8 rotatably attached to cover the liquid crystal panel 7, and a white plate 9 attached to the liquid crystal panel 7 side of the cover 8. 1 shows a printer device including

A liquid crystal panel 7 is used instead of the glass surface of a conventional copying machine, and an RS such as a personal computer 3 is used for this.
The screen is displayed on the liquid crystal panel 7 using the -232C output, and printing is performed in the same manner as copying is performed by the copying machine. Also,
If the driving power source of the liquid crystal panel 7 is turned off, the liquid crystal panel becomes colorless and transparent, and normal copying can be performed.

Then, the screen of the personal computer 3 is displayed on the liquid crystal panel 7 and the cover 8 is closed to prevent light from the outside, and printing is carried out in the same manner as normal copying. When it is used as a copying machine, the driving power source of the liquid crystal panel 7 is turned off, an object to be copied is placed on the colorless liquid crystal panel 7, and normal copying is performed.

Screen display data is sent from the personal computer 3 to the display control section 2 using the cable 10 and displayed on the liquid crystal panel 7. Further, the cover 8 for the liquid crystal panel is closed, and printing is performed in the same manner as operating the copier. When used as a normal copying machine, the display controller 2 is turned off, the liquid crystal panel 7 is made colorless and transparent, and the copying machine is operated to perform copying.

[0010]

Since the screen of a personal computer or the like is directly displayed on the liquid crystal panel, the processing in the printer is unnecessary and the printing time can be shortened.
