  According to the present invention, it is possible to easily and inexpensively implement a carbon fiber pattern that does not have a monotonous design and is rich in color shading.

  The present invention has been briefly described above. Further, details of the present invention will be further clarified by reading through the modes for carrying out the invention described below with reference to the accompanying drawings.

It is a longitudinal cross-sectional view of a part of dial for instrument of embodiment which concerns on this invention. It is a front view of the principal part which shows the printing pattern of the clear printing layer in FIG. It is a perspective view which expands and shows a part of printing pattern of the clear printing layer in FIG. FIG. 4 is a front view showing the appearance of the instrument dial in FIG. 3. It is a front view which shows the dial plate for conventional instruments. It is a longitudinal cross-sectional view which fractures | ruptures and shows a part of instrument dial in FIG.

  Hereinafter, an instrument dial according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of a part of the instrument dial, FIG. 2 is a front view of a print pattern of a clear print layer, and FIG. 3 is an enlarged perspective view showing an enlarged part of the print pattern. FIG. 4 is an enlarged front view of a part of the instrument dial surface. The same components as those shown in FIGS. 5 and 6 are denoted by the same reference numerals.

  First, reference numeral 15 denotes a dial plate that is substantially the same as the dial plate 2 shown in FIG. 5, and the dial plate 15 is a dial cloth formed by a light-transmitting synthetic resin plate such as acrylic resin or polycarbonate resin. It has a layer 9. When the instrument is attached to the dashboard of the automobile, a light source is located behind the dial fabric layer 9, and light emitted from the light source is incident on the rear surface of the dial fabric layer 9. When the light source is not located behind the dial fabric layer 9, a light guide that guides illumination light may be disposed on the rear surface of the dial fabric layer 9.

  Further, a display printing layer 10 representing the shape of the above-described scale 3 and numeral 4 is provided on the surface of the dial material layer 9. The display print layer 10 functions as a color filter when colored ink or paint is formed to a predetermined thickness by screen printing or the like. It is optional to give a predetermined design, for example, a pattern or color, to the scale 3, the number 4, or the characters printed here. The light transmitted through the dial fabric layer 9 described above is incident on the rear surface of the display printing layer 10, and at this time, the display printing layer 10 receives a specific light out of the light transmitted through the dial fabric layer 9. Light having a wavelength is transmitted and emitted from the front surface of the display printing layer 10.

  Further, a light-shielding background print layer 11 having a dark color such as black or gray as a background color is provided on a portion of the surface of the dial fabric layer 9 where the display print layer 10 is not provided. It is given to. As the background print layer 11, for example, a coating layer of a light reflective paint can be used. In this case, the background print layer 11 can reflect light having a different hue from the display by the display print layer 10 such as the scale 3, the number 4, and characters. The light transmitted through the dial material layer 9 described above is incident on the rear surface of the background print layer 11. At this time, the background print layer 11 blocks light propagation to the front surface of the display print layer 10. . The background print layer 11 is also provided on the surface of the end portion of the display print layer 10.

  Further, a clear print layer 12 is provided on the upper surface of the background print layer 11. As shown in FIGS. 2 and 3, the clear print layer 12 is a linear portion A including a plurality of linear bodies 12 a disposed substantially parallel to each other, and is also disposed substantially parallel to each other. It is formed by a linear portion B having a set of a plurality of linear bodies 12b. In FIGS. 2 and 3, a set constituted by five long linear bodies 12 a is represented by a linear part A, and a group constituted by five short linear bodies 12 b is represented by a linear part B. , And. The length of the linear body 12b in the longitudinal direction substantially coincides with the width of the linear portion A constituted by the five linear bodies 12a.

  In addition, one of the linear bodies 12a and 12b of the linear portions A and B has a linear shape, and two linear bodies 12a and 12b on both sides sandwiching the central one are respectively It has an arc shape and is arranged in line symmetry.

  The linear part A and the linear part B are arranged adjacent to the surface of the background printing layer 11 so that the longitudinal directions of the linear bodies 12a and 12b are orthogonal to each other. FIG. 2 shows a state in which a total of four linear portions are arranged, but with respect to one linear portion A, in the longitudinal direction of the linear body 12a of the linear portion A and in the longitudinal direction. It is arranged on the surface of the background printing layer 11 so that four linear portions B are adjacent to each other in the four directions before and after the orthogonal direction (for one linear portion B, four lines are arranged in the above four directions. The shape portion B is adjacent.).

  In FIGS. 2 and 3, the lengths of the linear bodies 12 a and 12 b constituting the linear portions A and B are made different, but this difference in length is not essential to the present invention. It may be the same length. If it is the same length, a uniform checkered carbon fiber pattern can be expressed.

  When light L is incident on the clear printed layer from the front of the meter of the present invention as indicated by the arrows in FIG. 3, even if light L having the same intensity is incident from the same direction, the linear bodies 12a and 12b The traveling direction of reflected and refracted reflected light is not constant. In addition to the phenomenon that the reflected light interferes with the incident light, the brightness of the light is caused by the phenomenon that the reflected lights reflected by the surfaces of the linear bodies 12a and 12b interfere with each other. Therefore, in this embodiment, a texture pattern similar to the carbon fiber pattern can be displayed in a checkered pattern.

  FIG. 4 shows an enlarged part of the carbon fiber pattern P obtained by the clear print layer shown in FIGS. 2 and 3. The carbon fiber pattern P observed by the clear printing layer 12 is a checkered pattern. In this checkered pattern, a light and shade pattern appears as if carbon fibers are braided, and the light and shade changes variously depending on the viewing direction, and a carbon fiber pattern with a different texture can be expressed.

  Various thicknesses, lengths and widths of the layers of the linear bodies 12a and 12b, and shapes (straight lines and curves) and arrangements of the linear bodies 12a and 12b, and how the linear portions A and B are arranged By adjusting, the texture of the carbon fiber pattern expressed by the instrument of the present invention can be further increased to a level close to that of the actual carbon fiber.

  In addition, when the linear portions A and B are alternately arranged so that the linear bodies 12a and 12b are orthogonal to each other, they can be expressed as a pattern similar to a carbon fiber knitted in a checkered pattern, and can be observed respectively. However, when the linear bodies 12a and 12b of the linear portions A and B are both arranged in the same direction, they can be expressed as a pattern similar to a striped carbon fiber.

  In addition, when providing a warning display with a warning display, there are many cases where the temporarily lit area is usually blacked out, but it is also possible to add a pattern to the vacant space. A degree of freedom can be given.

  As mentioned above, according to the dial plate for instruments which concerns on embodiment of this invention, by arrange | positioning the clear printing layer 12 comprised from several linear body 12a, 12b on the surface of the printing layer 11 for background, the linear A difference in brightness occurs due to reflection and refraction of light incident on the bodies 12a and 12b. As a result, the driver who visually recognizes the dial for the instrument looks as if the carbon fiber pattern is reproduced on the instrument.

  In addition, the thickness, length, and width of each linear body 12a and 12b, or the shape (straight and curved) and arrangement of the linear bodies 12a and 12b, and how the linear portions A and B are arranged, etc. By making various adjustments, the texture of the carbon fiber pattern expressed by the instrument of the present invention can be further increased to a level close to that of the actual carbon fiber.

  Further, when the linear portions A and B are alternately arranged so that the linear bodies 12a and 12b are orthogonal to each other, the linear shape of the linear portions A and B is similar to a pattern similar to a carbon fiber knitted in a checkered pattern. When the bodies 12a and 12b are both arranged in the same direction, they can be expressed as a pattern similar to a striped carbon fiber.
