Field of the Invention The present invention relates to an image forming apparatus, and more particularly to an image forming apparatus using a thermal sublimation technique and a thermal sublimation type printer using the same. [Prior Art] The familiar imaging technology is widely used in photo printing. The dry solid ink on the color ribbon of the Liuyi 驭丄 boundary layer, that is, the mixture of toner and polymer, is thinly coated on the ribbon. It is divided into yellow, cyan, and magenta, which are slightly larger than the photographic paper size of the paste. When printing, the photographic paper and the ribbon pass through a printing roller at the same time, and are heated under the printing head. 'The single crystal stone with a diameter less than 4 〇μπι on the print head is energized and applied to the ribbon. The dry solid ink melts on it. During the heating process, at about 32 Fahrenheit, the heat separates the polymer molecules. When the head is over, the temperature drops, and the ink changes from a gaseous state to an ink-embedded polymer. The polymer molecules are polymerized in the same way. When a color is printed, the color is formed from the __ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ There are two modes that need to be switched between the two types of papers: paper picking, paper feeding, roll paper color I and 歹J ρ printing. Only one color will be transferred to the paper and will be loaded. Generally, a protective layer must be added, so the paper is printed and printed: two fixed:: four times. In the printing mode, the column and the force are evenly transferred onto the paper. In the advance and retreat machine, in order to achieve the power of the outline, take the paper, to achieve this action to the wheel or other institutions to complete the switch, it will increase production costs and printing time.丄 341796 SUMMARY OF THE INVENTION An object of the present invention is to provide a low-level image forming apparatus that saves printing time and a thermal sublimation type printer that is used in the prefecture.

The lower side, as shown in Fig. 5. In addition, the second end 82 extends in a direction away from the first end 81 to a second portion of the printing roller 30, and the second end 82 The width of the two portions is extended to be greater than the length of the printing roller 30. The second end portion of the second end 82 extends perpendicularly to a sidewall 821, 822 at both ends of the width direction, and the sidewalls 821, 822 can The rollers 31 of the printing roller 30 are in contact with each other, and the side walls 82 are respectively provided with pivot points 825 and 826 for connecting the lifting cardboard 80 to the frame 1B. The pivot points 825 and 826 are respectively arranged. Located on the same level line and two points determine that a line forms an imaginary axis, and the lifting plate 80 can rotate about the imaginary axis formed by the pivot points 825, 826. When the printing roller 30 moves downward, the roller 31 of the printing roller 30 presses the side walls 821, 822 downward, so that the pivot points 825, 826 on the lifting plate 80 are close to the printing roller side. Partially pressed down, due to the principle of leverage, the other side of the upper shaft points 825, 826 of the lifting cardboard 80 is lifted away from the printing roller, that is, the φ portion near the paper cassette, and the paper in the paper cassette can be lifted up. The side wall 82 of the side wall 82 is adjacent to the end of the printing roller 30. A pair of engaging grooves 823 and 824 are disposed. When the printing roller 30 moves downward, the roller 31 can just fall into the engaging grooves 823 and 824. The paperboard 80 is pressed to rotate about the virtual axis formed by the pivot points 825, 826. Specifically, the pivot points 825, 820 may be a card slot structure as shown in FIG. 4, and more specifically, as shown in FIG. 7, the connection of the lifting cardboard 8〇 to the frame 1〇 is via a lining. The sleeve 86 is completed by a rivet 861 fixed to the frame 10, and the lifting cardboard 80 is snapped onto the rivet 861 extending from the frame to the bushing 86 via the card slot structure, and the lifting cardboard 80 can surround the rivet 861 The rivet 861 rotates. Of course, the nail 861 can also be replaced by a shaft extending from the frame 12 1341796; and one of the pivot points 825, 826 can also be a circular hole structure, as long as the lifting cardboard 80 can be attached to the frame. 1 〇 and rotate with it as a fulcrum. Next, as shown in FIG. 6, the thermal sublimation printer includes a paper cassette 200 including a chassis 210, a tray 22 and an upper cover 23, the chassis 210 including a bottom surface.

The paper tray 22 includes a movable end 221 and a fixed end 222 opposite to the movable end 221. The movable end 221 is covered. On the hollowed out portion 212. The first end 81 of the lift plate 80 penetrates into the hollowed out portion 212. When the first end 81 of the paperboard 80 is upturned, the movable end 221 of the paperboard 22 can be lifted. Wherein the force provided by the printing roller shaft forcing the second end 82 of the lifting paper to be lowered is the same during each paper taking process, and the force arms are also the same, so the number of sheets placed on the paperboard 220 At the same time, due to the difference in the total gravity of the paper, the resistance of the first end 81 of the lifting paper 80 is different, and in order to provide a certain paper take-up pressure (ie, the first end 81 is upturned to press the paper on the take-up roller) The force of the present invention is such that the lift plate 80 is divided into a first end 81 and a second end 82, and a torsion spring 84 is disposed between the first end 81 and the second end 82. The structure 'ensifies that the first sheet of paper in the paper pick has the same paper take-up pressure as the last sheet. Continuing to refer to Fig. 3, above the first end 81 of the paperboard 80, the frame 10 is further provided with a pickup roller 50, and the pickup roller 50 is provided with pickup rollers 51, 52. A pair of paper discharge rollers 57, 58 are correspondingly provided above the pickup rollers 51, 52. 13 1341796 The printer includes a transfer unit 'the transfer unit pack-pressing paper-transmission system'. The pair of transport rollers includes a paper feed roller and a :r_: two ==== setting. , :: layer "" can ensure that the paper will be printed back and forth in the same position as shown in Figure 8 and Figure 3. When needed, the front 4C of the twisting axis 4C also rotates clockwise. The first-axis lining, the lower swing' causes the printing roller 3G to move downward, and the roller (four) is embedded in the 823, 824 to press the pivot point 825, 826 on the lifting plate 80 - the side is close to ^ = part of the wheel 3G moves downwards, due to the principle of the lever, the lifting plate 80 is rotated with the pivot points 825, 826 as the fulcrum, that is, the point 825, the other side of the tar, and the first end 81 are up, thereby lifting _ The paper ^ contacts 4 pick-up rollers 5 52. During the paper picking process, the stepping motor can be stopped from being energized. 'Because the full-rod turbine has a self-locking function, the stepping motor is not working 2' the scroll 7〇, the turbine 71, the first gear 72, the The second gear 73 and the printing roller shaft 4G_ are both in a stationary state without being reversed or continued to rotate due to the force of the basin. After the paper is taken, the scroll 70 rotates counterclockwise, and the rotating shaft 4〇 also reverses the 'the first turn 41, 42 to the county, finely moves the noisy 30 to the flat position, and the lifting cardboard 8G is also restored. The flat position, as shown in the ninth riding, is transmitted to the printing area by the transfer unit. The stepping motor 60 can also be deactivated during paper transport. 14 1341796 When the paper is inspected for the fourth (four) printing difficulty (four), the rod % turns 'the shaft 40 also continues to rotate counterclockwise, the scale _ her 4 疋: move' causes the printing roller 3 〇 to contact the print head 2. The printing roller shaft 4G continues to rotate counterclockwise, but since the printing roller 3 of the printing head 20 can no longer move upward, the first axes 41, 2 also stop rotating, and the rotating shaft Continued rotation of 4〇 drives the lining:=, thereby pulling the twisting of the first bushing and the second bushing 43 and the direction of the twisting force of the first hand: the first bushing 41, 42 continue the trend to provide upward printing pressure for the printing roller 3〇. ^ From the 'stop Nago 6G Lai, due to the scroll: the rod 70, the wheel 71, the first -_, the ^ gear 73 U batter _ 4 () axis (four) obstruction 43, 44 to maintain a stable torque To provide stable printing pressure. At the time of printing, the entire sheet of paper on which the image is to be printed is cut, that is, the entire sheet of paper is prepared from the printing, and the stepping motor 6 is started. And control the thirsty rod 7. 'Two over two printing areas, then 疋 ^ The 〇 4 〇 also rotates clockwise, first release 4 torque, and then make the first bushing 4, 4 leave the print head 20, and continue down The & prints the roller 30. At this time, the paper is ejected, and (4) = the position of the flat position as shown in Fig. 9, when the stepping motor 60 is not = color = back - (5) position, the stepping motor 6G is restarted, 胄^ Capture back to print to prepare to print another color. For example, if the wheel 30 resumes the printing position, it is one-person or four times. After the printing of the required 1341796 print on a piece of paper is completed, the paper is completely removed from the machine, and the printing is completed. To the lowest position as shown in Fig. 8, start to take off a piece of paper to prepare for the printing operation. Need special explanation, this embodiment only needs to make the printing roller shaft in the process of switching between the advance and reverse paper and the printing state. 4〇 rotates 35 degrees, and in the printing process, this switching action needs to be done 8 times' Therefore, the device can effectively shorten the printing time. In addition, in the process of taking paper, feeding back and printing and printing, it can be fully profitable (4) The self-locking function of the wheel "stops giving the motor 60 Wei, (4) about energy.
