Description

Technical Field

[0001] The utility model belongs to the technical field of electronic stationery, in particular to a multifunctional copying device. Background Art

[0002] There are three mainstream ways of practicing calligraphy: copying from a copybook, imitating with a copybook and copying with the aid of a model character. Copying from a copybook requires practicing on the transparent practice paper attached to the copybook, which limits the selection of practice paper and reduces the utilization rate of the copybook. When copying from a copybook, it is difficult to master the handwriting and structure of the practiced font, and it is difficult to fully understand the artistic characteristics of the practiced font. When copying with the aid of a model character, due to the concave structure of the model character, the artistic quality of the font is not perfect and rich enough, and the selection of fonts is limited, making it difficult to practice complex fonts.

[0003] When copying paintings, it is difficult to grasp the state and direction of the lines due to the limitations of the painter's touch and understanding of the original work, which affects the realism of the entire work; also when manually copying engineering drawings, accurately grasping the size and position relationship between the lines requires a lot of time, which reduces work efficiency.

[0004] Therefore, the present application proposes a multifunctional copying device which utilizes LED technology to make practicing calligraphy and copying paintings simple and convenient to solve the above problems. Utility Model Content

The touch key screen 101 is supported by an acrylic plate, on which a power on key, an on / off key, a brightness plus / minus control key, and a light effect control key are integrated. Selection keys, etc., the control element board 102 is supported by a printed circuit, and the electronic components mainly include a single-chip microcomputer, resistors and capacitors, etc. The control unit LED board 103 uses an LED light-emitting lamp installed on an aluminum substrate to provide a light source for the control unit 1. The touch key screen 101 is connected to the touch key 106 and the control element board 102. The touch key screen 101 controls the opening and closing of the first LED substrate 202 and the second LED substrate 203 and the adjustment of the brightness. In addition, a display screen 107 is also provided on the light source box 201. The display screen 107 is used to display time, year, etc., and is powered by the power supply terminal 104.

[0041] The diffuser plate 205 is made of a plastic plate with a thickness in the range of 0.8mm to 1.2mm, the light guide plate 206 is made of an acrylic plate with a thickness in the range of 3.8mm to 4.0mm, the dust shield plate 208 is made of a thick cardboard with a thickness in the range of 0.8mm to 1.0mm, and a non-slip rubber pad 210 is also installed at the bottom of the bottom cover 209, and the non-slip rubber pad 210 is made of a foam board with a thickness in the range of 1.6mm to 1.8mm.

[0042] When in use, choose the light pad 402 or the strip frame pad 403 according to the specific situation. The light pad 402 is a soft plastic plate with a thickness in the range of 0.8mm to 1.0mm. The strip frame pad 403 is a soft plastic plate with the same specifications and performance as the light pad 402. The difference between the light pad 402 and the strip frame pad 403 is that the strip frame pad 403 has a grid of different styles. The light pad 402 is suitable for copying paintings and drawing engineering drawings, etc., and the strip frame pad 403 is suitable for practicing calligraphy. The grid style of the strip frame pad 403 is as shown in the attached figure. Figures 13-15 As shown;

[0043] After placing the light pad 402 or the strip frame pad 403 on the diffuser 205, first place the copy work 6, then lay the practice paper 5 on the copy work 6, and then press the laser ruler bar 401 on the edge of the practice paper 5. The laser ruler bar 401 is adsorbed on the built-in magnet 204 through the magnetic metal strip 404 set inside it. The built-in magnet 204 is installed between the diffuser 205 and the light guide plate 206. After the laser ruler bar 401 is adsorbed, turn on the laser ruler bar 401 to project a grid on the practice paper. The touch key screen 101 on the control unit 1 controls the first LED substrate 202 or the second LED substrate 203 in the light source box 201 to be powered on and control its brightness. The first LED substrate 202 and the second LED substrate 203 can also be powered on at the same time. Under the action of the diffuser 205 and the light guide plate 206, the shadow on the copy work 6 is projected on the practice paper 5, and you can copy painting or practice calligraphy on the practice paper 5.

[0044] Embodiment 2, combined Figure 1-Figure 16 The multifunctional plotter of the present embodiment is used to form a smooth transition between the light source box 201 and the desktop when the light source box 201 is placed on the desktop. The height difference between the light source box 201 and the desktop brings inconvenience to writing. The supporting unit 3 forms a smooth transition between the light source box 201 and the desktop. The main chassis card slot 212 is processed on the side wall of the light source box 201. The front supporting frame 301 and the right supporting frame 303 of the supporting unit 3 are connected to the main chassis card slot 212 through the front supporting frame claw 304 and the right supporting frame claw 305. 12 clamping, a corner support frame 302 is also connected between the front support frame 301 and the right support frame 303, and the corner support frame 302 is clamped with the front support frame 301 and the right support frame 303 through the corner support frame claw 306. Under the action of the front support frame 301, the corner support frame 302 and the right support frame 303, a smooth transition is formed between the light source box 201 and the desktop, and the user will not be affected in writing and drawing due to the high height difference between the desktop and the light source box 201 when using it.

[0045] Embodiment 3, combined Figure 1-Figure 16 To illustrate the present embodiment, the multifunctional copying device of the present embodiment has a mounting hole 213 processed on the bottom cover 209, and the expansion screw 214 passes through the mounting hole 213 to fix the bottom cover 209 on the wall 8, and then the light source box 201 and its internal structure are installed, so that the light source box 201 can be hung on the wall to have a lighting effect, and calligraphy practice and copying painting can continue on the light source box 201 placed flat on the wall.

[0046] This embodiment is only an illustrative description of the present application and does not limit its protection scope. Those skilled in the art may also make partial changes thereto, and as long as they do not exceed the spirit of the present application, they are all within the protection scope of the present application.
