Abstract

The invention discloses a non-carbon printer. The printer is provided with a laser transmitter. As the printer is provided with the laser transmitter, after a signal output by a computer is subjected to high-frequency modulation by a high-frequency modulation unit of the laser transmitter, a signal output by the high-frequency modulation unit is converted into a character dot matrix signal by a data conversion unit and then a laser beam with character information is directly irradiated onto a paper surface in a mode of centralizing energy by an optical unit, so that the paper surface scanned by the laser beam is instantaneously carbonized into brown writing and no carbon powder printing is realized. Therefore, the non-carbon printer is low-carbon and environmental-friendly.

Example Embodiment

[0018] In order to further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0019] See figure 1 and figure 2 , The carbon-free printer of the present invention includes a cylindrical main body 1 and a brim-shaped paper discharging section 2 extending from one side of the main body 1 outwards. A paper inlet 11 is provided on one side of the paper portion 2, and a plurality of heat dissipation holes 12 arranged in a row are provided on the lower part of the paper inlet 11. A USB interface 13 is provided on one side of the heat dissipation hole 12 at one end of the main body 1. The end of the main body 1 is provided with a switch 14. An arc-shaped paper outlet 21 is provided on the side of the paper ejecting portion 2, and a progress indicator bar 22 made of LED lights is provided on the upper surface of the paper ejecting portion 2.
[0020] See image 3 and Figure 4 A laser transmitter 15 and a paper feeding mechanism 16 are provided in the main body 1, and the laser transmitter 15 is provided with a high frequency modulation unit 151, a data conversion unit 152 and an optical unit 153 which are electrically connected to each other. The high-frequency modulation unit 151 is used for high-frequency modulation of the signal output by the computer. The data conversion unit 152 is used to convert the signal output by the high frequency modulation unit 151 into a character dot matrix signal. The optical unit 153 is provided with a mirror 1531 and a convex lens 1532. The mirror 1531 is used to reflect the laser beam carrying character information to the convex lens 1532, and the convex lens 1532 is used to concentrate the energy of the laser beam. It directly hits the paper surface of the paper 3 placed on the paper feeding mechanism 16. The paper feeding mechanism 16 is provided with a plurality of paper feeding rollers 161 through which the printed paper 3 can be sent out of the printer through the paper outlet 21. The progress of printing can be observed through the progress indicator bar 22.
[0021] In summary, the carbon-free printer of the present invention is equipped with the laser transmitter 15, the high-frequency modulation unit 151 of the laser transmitter 15 performs high-frequency modulation on the signal output by the computer, and then the data conversion unit 152 The signal output by the high-frequency modulation unit 151 is replaced with a character dot matrix signal, and the optical unit 153 concentrates the energy of the laser beam carrying character information directly onto the paper surface, thereby instantly carbonizing the paper surface scanned by the laser beam Brown handwriting can be printed without toner, which is low-carbon and environmentally friendly.
[0022] The above-mentioned embodiment only expresses an embodiment of the present invention, and its description is more specific and detailed, but it should not be understood as a limitation to the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
