The structure and function of the solution of the present application will now be described in detail with reference to fig. 1 to 2.

The first embodiment:

a first embodiment of the present invention provides a printing apparatus including:

the main body frame has a paper path S1.

And a printing unit 2 disposed on the main body frame and configured to perform printing on the printing medium 1 fed along the paper path S1.

And a driving unit disposed on the main body frame and having a paper feed roller 5 for feeding the printing medium 1.

The printing unit 2 is electrically connected to the driving unit.

Wherein the printing unit 2 includes a developing mechanism 3 and a fixing mechanism 4 which are provided in this order in a feeding direction of the printing medium 1; the developing mechanism 3 includes a plurality of light emitting elements 31 arranged in a line, each light emitting element 31 includes a light source capable of emitting light of a different wavelength, and light emitted from different light sources of the same light emitting element 31 is focused on a predetermined plane.

The fixing mechanism 4 has a thermal head 41 capable of heating the printing medium so that the printing medium 1 developed by the developing mechanism 3 can display a corresponding image.

In the present embodiment, the driving unit is disposed in the main body frame, and the driving unit includes a paper feeding roller 5 for feeding the printing medium 1 and a driving member (for example, a stepping motor) for driving the paper feeding roller 5 to rotate to feed the printing medium 1, and the printing medium 1 can be fed in the paper feeding path S1 along a predetermined direction by the driving of the driving member.

In the embodiment, the number of the light emitting assemblies 31 is plural, and the light emitting assemblies 31 are arranged in a straight line and fixed on the strip-shaped supporting frame 34 of the developing mechanism 3, each light emitting assembly 31 can emit light with a predetermined intensity and a predetermined wavelength under the control of the controller of the printing apparatus, and the light is focused on the same line of the printing medium 1. Generally, each light emitting element 31 corresponds to a print dot on the print medium 1, so that the greater the number of light emitting elements 31, the higher the resolution of the printed image.

In the present embodiment, a plurality of pigment layers are provided on the printing medium 1. When the light is focused to a certain point on the printing medium 1, the printing medium 1 can determine which pigments are developed and how much pigments are developed according to the light.

For example, if the printing medium 1 is provided with three pigment layers of Cyan, Yellow and Magenta, the light emitting assembly 31 includes three light sources (the light sources may be UV lamps), which are a UV _ C lamp (generally, the color of the emitted light is also Cyan) for emitting the light for developing Cyan (Cyan), a UV _ M lamp (generally, the color of the emitted light is also Magenta) for emitting the light for developing Magenta (Magenta), and a UV _ Y lamp (generally, the color of the emitted light is also Yellow) for emitting the light for developing Yellow (Yellow). The light source can be fixedly arranged on a base plate. It is understood that in other embodiments, the wavelength or color of the light emitted by each light source may be different according to the pigment layer of the printing medium 1, and the number of light sources included in each light emitting assembly 31 is not limited to 3, which is determined according to the pigment layer of the printing medium 1, and the invention is not limited thereto.

In the present embodiment, the controller of the printing apparatus may control the operation of each light emitting assembly 31 according to the received data to be printed. For example, for a first pixel to be printed, the color of the first pixel is cyan, and the color depth is 50, the controller controls the UV _ C lamp of the light emitting component 31 corresponding to the first pixel to emit light, and the intensity of the light corresponds to 50. For the second pixel point to be printed, the color is green, and the color depth is 20, then the controller controls the UV _ C lamp and the UV _ Y lamp of the light emitting component 31 corresponding to the pixel point to emit light, and the light intensity corresponds to 20. Obviously, the deeper the color depth, the stronger the corresponding light intensity should be.

In the present embodiment, based on the above-mentioned operation, the controller sequentially controls each light emitting assembly 31 according to the data to be printed of the current line, so that each printing point on the printing medium 1 can be photo-developed. After finishing the photo-development, the printing medium 1 is driven by the driving unit to continue to advance along the paper feeding path S1 and enter into the working range of the fixing mechanism 4, the fixing mechanism 4 heats the thermal head 41, so that heat is transferred to the printing medium 1 by the thermal head 41, and the photo-developed printing dots on the printing medium 1 finish the thermal fixing by the heat, i.e. will display the pigment of the corresponding color, wherein, the amount of the displayed pigment is determined according to the light intensity.

It should be noted that the printing unit 2 further includes a transmission mechanism, and the transmission mechanism is connected to the fixing mechanism 4 and can drive the fixing mechanism 4 to move in a direction close to the paper feeding path or away from the paper feeding path under the driving of the driving unit.

When the fixing mechanism 4 is not in operation, the fixing mechanism 4 is located relatively far away from the paper feeding path S1, and when the thermal fixing operation needs to be performed, the fixing mechanism 4 is driven by the transmission mechanism to be located relatively close to the paper feeding path S1, so as to facilitate thermal fixing.

In summary, the printing apparatus provided by the embodiment of the present invention is configured with the developing mechanism 2 and the fixing mechanism 3 sequentially configured along the feeding direction, the developing mechanism 2 performs photo-development on the printing medium 1, and after the photo-development is performed, the fixing mechanism 4 performs thermal fixing on the developed printing mechanism, so that the image to be printed is reproduced on the printing medium.
