It is a figure for demonstrating the relationship between a dot pattern and a 1st direction. It is a figure for demonstrating the relationship between a dot pattern and a 1st direction.

  A dot pattern display and an instrument device according to an embodiment of the present invention will be described. The instrument device 10 is a vehicular pointer-type instrument mounted on a vehicle, and as shown in FIGS. 1 and 2, a circuit board 20, a pointer 30, a light guide 40, a light source 21, and a pointer drive unit 22, The control unit 23 and the dot pattern display body 100 (here, the instrument panel) are provided. In FIG. 2, all of the light source 21, the pointer driving unit 22, the control unit 23, the pointer 30, and the light guide 40 are omitted from the cross-sectional structure and the hatching representing the cross section.

  The circuit board 20 is formed by forming a predetermined wiring pattern (not shown) on a plate-like base material made of, for example, glass fiber-containing resin, and is mounted with a light source 21, a pointer driving unit 22, a control unit 23, and the like. Yes.

  The light source 21 includes an LED (Light Emitting Diode) and the like, and is electrically connected to the control unit 23 via a wiring pattern formed on the circuit board 20. The light source 21 is lit (emitted) under the control of the control unit 23 and emits light to the light guide 40.

  The pointer driving unit 22 includes a stepping motor and the like, and is electrically connected to the control unit 23 through a wiring pattern formed on the circuit board 20. The pointer driving unit 22 has a rotation shaft 22 a and rotates the rotation shaft 22 a under the control of the control unit 23. A pointer 30 is fixed to the rotary shaft 22a. For this reason, when the rotating shaft 22a rotates, the pointer 30 rotates.

  The control unit 23 includes a microcomputer including a CPU (Central Processing Unit), a predetermined processing circuit, and the like. Predetermined information is supplied from the outside (for example, an electronic control unit (ECU) or the like), and the light source 21 and the pointer driving unit 22 are driven and controlled according to the supplied information. The control unit 23 turns on or off the light source 21. Further, the control unit 23 controls the pointer driving unit 22 to rotate the rotation shaft 22a so as to have a predetermined rotation angle.

  The pointer 30 is formed of synthetic resin or the like, and indicates an indicator unit 100a described later formed on the dot pattern display body 100 by rotating with the rotation of the rotating shaft 22a.

  For example, the control unit 23 controls the pointer driving unit 22 based on vehicle speed information supplied from the ECU to rotate the rotating shaft 22a at a rotation angle corresponding to the vehicle speed information. Along with the rotation of the rotating shaft 22a, the pointer 30 also rotates, and the user is notified of the vehicle speed (such as a driver of the vehicle) by instructing an index unit 100a (vehicle speed scale or the like) described later.

  The light guide 40 is disposed between the dot pattern display body 100 (instrument panel) and the circuit board 20. The light guide 40 is made of a predetermined synthetic resin, is transparent, and guides light. The light guide 40 includes a light receiving unit 41, a reflecting surface 42, a reflecting unit 43, and an emitting unit 44.

  The light receiving unit 41 faces the light source 21 and receives light emitted from the light source 21. The light received by the light receiving unit 41 is guided by being internally reflected by the light guide 40 and proceeds through the light guide 40. The reflection surface 42 is formed by the inner surface of the light guide 40 and reflects the light received by the light receiving unit 41 and guided by the light guide 40 toward the emission unit 44. The light reflected by the reflecting surface 42 is further guided through the light guide 40 and is irregularly reflected toward the emitting portion 44 by the reflecting portion 43 formed of unevenness provided on the surface facing the emitting portion 44. The The irregularly reflected light is emitted from the emitting portion 44 in a planar shape. Thus, the light guide 40 guides the light received by the light receiving unit 41 and emits the light in a planar shape from the emitting unit 44 (see the arrow in the light guide 40 in FIG. 2).

  The emission part 44 is configured to cover an index part 100a described later from the circuit board 20 side. For this reason, the whole indicator portion 100a is illuminated in a planar shape by the light emitted from the emitting portion 44. In FIG. 2, only one light source 21 and light receiving unit 41 are provided, but in actuality, these are provided at appropriate locations together with the reflecting surface 42 and the like, and are emitted from the emitting unit 44 in a planar shape. Make the light more uniform.

  The dot pattern display body 100 includes a base material 111, a diffusion layer 112, and a decoration layer 113.

  The base material 111 is made of a colorless and transparent plate-like member formed from a synthetic resin or the like.

  The diffusion layer 112 is formed on the back surface of the substrate 111 by a predetermined method, and diffuses the light emitted from the emission unit 44. The diffusion layer 112 is a white print layer formed by, for example, printing using a white ink or the like. The diffusion layer 112 emits light emitted from the emission unit 44 to the base material 111 side in a diffused state. Thereby, more uniform planar light is incident on the substrate 111. The diffusion layer 112 may have a shape that covers the indicator portion 100a formed on the decorative layer 113 from the circuit board 20 side.

  The decoration layer 113 is formed on the surface of the base material 111 by printing or the like, decorates the base material 111, and expresses the index portion 100a of FIG. The decorative layer is composed of one or more layers formed by printing or the like with a predetermined ink, and expresses the indicator portion 100a.

  The indicator part 100a is for informing the speed of the vehicle by being instructed by the pointer 30, and is provided in correspondence with each of a plurality of scales and a part of the scales. (Number representing the vehicle speed). In this embodiment, the scale and the numbers are composed of portions that transmit light, and the other portions are composed of portions that block light. Of the scales, the large scale 100aa provided corresponding to the number representing the vehicle speed is expressed in black and white gradation. This gradation is expressed by a dot pattern 105 (see FIG. 3C) described later.

  For example, a black print layer that blocks light is formed on the surface of the base material 111 by printing a solid portion (for example, screen printing) on the surface of the substrate 111 with a black ink or the like, and the large scale 100aa Forms a dot pattern 105 to be described later by printing or the like. The dot pattern 105 is formed in black except for the dot portion. As a result, the scale (dot portion in the large scale 100aa) and numbers are removed from the decorative layer 113, and the diffusion layer 112 is exposed at this portion.

  Since the diffusion layer 112 is white, the scale (dot portion in the large scale 100aa) and the numbers become white due to the exposure of the diffusion layer 112. For this reason, the scale (dot portion in the large scale 100aa) and the number are visually recognized by the user due to the scale (dot portion in the large scale 100aa) and the white color of the number and the black color of the other portions. . When the light source 21 is not lit, the scale (dot portion in the large scale 100aa) and the numbers appear white due to external light, and when the light source 21 is lit, the light emitted from the light source 21 and guided and emitted by the light guide 40 However, by passing through the diffusion layer 112 and the substrate 111, the scale (dot portion in the large scale 100aa) and the numbers appear white.

  Next, the dot pattern of the large scale 100aa will be described. The dot pattern is constituted by the first graphic pattern 120 and the second graphic pattern 130 formed as a part of the decoration layer 113 on the surface of the base material 111.

  The first graphic pattern 120 is formed on the surface of the base 110 by screen printing using black ink or the like, and is black. As shown in FIGS. 3A and 4A, the first graphic pattern 120 is composed of a plurality of first graphics 120a extending along the first direction.

  Each of the first figures 120a is a figure extending linearly along the first direction, and has one end (upper end in FIG. 4A) centered on the center line 120aa along the first direction. From the other end (the lower end in FIG. 4A), the width gradually increases. Each first graphic 120a is arranged along a direction (first orthogonal direction) orthogonal to the first direction at intervals so that the center lines 120aa are parallel to each other. The intervals (pitch) between the center lines 120aa of the adjacent first figures 120a are the same. That is, the first graphics 120a are arranged so that the center lines 120aa are equally spaced. The width of an area sandwiched between adjacent first figures 120a (area where the first figure 120a is not formed) gradually decreases from the one end to the other end.

  The second graphic pattern 130 is formed by screen printing using black ink on the surface of the substrate 110 on which the first graphic pattern 120 is formed, overlaid on the first graphic pattern 120, and becomes black. Yes. As shown in FIGS. 3B and 4B, the second graphic pattern 130 is composed of a plurality of second graphics 130a extending along the second direction. The second direction is set to a direction substantially orthogonal (including orthogonal) to the first direction (see FIG. 4C).

  Each of the second figures 130a is a figure extending linearly along the second direction, and one end (upper end in FIG. 4A) centering on the center line 130aa along the second direction. From the other end (the lower end in FIG. 4A), the width gradually increases. The second figures 130a are arranged along a direction (second orthogonal direction) orthogonal to the second direction with a space therebetween such that the center lines 130aa are parallel to each other. The intervals (pitch) between the center lines 130aa of the adjacent second figures 130a are the same. That is, the second graphics 130a are arranged so that the center lines 130aa are equally spaced. The width of an area sandwiched between adjacent second figures 130a (area where the second figure 130a is not formed) gradually decreases from the one end to the other end.

  The first graphic pattern 120 and the second graphic pattern 130 are formed so as to overlap each other so that the first graphic 120a and the second graphic 130a intersect (see FIG. 5). As a result, the region sandwiched between the first graphic 120a and the region sandwiched between the second graphic 130a (the region where the first graphic 120a and the second graphic 130a are not formed, that is, the decorative layer) 113) is formed, and this region becomes the dot 105a. Here, the dot 105a has a quadrangular shape. On the other hand, the first graphic pattern 120 and the second graphic pattern 130 form a region (background) other than dots. A dot pattern 105 is formed by the plurality of dots 105a and the background (see FIG. 3C).

  In this embodiment, the size of the dot 105a becomes smaller as the dot 105a is positioned in the downward direction in FIG. This is because the width of the first graphic 120a and the second graphic 130a becomes wider toward the lower side, and the first graphic 120a and the second graphic 130a are formed toward the lower side. This is because the area that is not present becomes smaller. In this embodiment, gradation is expressed by changing the size of the plurality of dots 105a formed by the first graphic pattern 120 and the second graphic pattern 130 in this way. For example, if the first graphic pattern 120 and the second graphic pattern 130 are black, the substrate 110 is colorless and transparent, so that the first graphic pattern 120 and the second graphic pattern 130 are formed. As a result, as shown in FIG. 2C, a black gradation with a thin upper side and a dark lower side is expressed.

  As a method for forming the dot pattern 105, for example, after the first graphic pattern 120 is formed on the surface of the base material 111 by screen printing, the first graphic pattern 120 is formed on the surface of the base material 120 on which the first graphic pattern 120 is formed. The first figure 120a and the second figure 130a intersect with each other at a predetermined angle (so that the center line 120aa and the center line 130aa intersect at a predetermined angle). Two graphic patterns are formed by screen printing. At this time, the second graphic pattern 130 may be formed after the first graphic pattern 120 is dried.

  In this embodiment, with the above configuration, in the dot pattern display body 100, the plurality of first figures 120a that extend along the first direction and are arranged in parallel with a gap are formed on the base material 111. A first graphic pattern 120 to be represented, and a second graphic pattern 130 to represent a plurality of second graphics 130a extending in a second direction substantially orthogonal to the first direction and arranged in parallel at intervals. Are overlapped, and a plurality of first graphics 120a and a plurality of second graphics 130a intersect to form a dot 105a in an area where the first graphics 120a and the second graphics 130a are not formed. The dot pattern 105 is displayed. In the present embodiment, with such a configuration, dots are not directly formed by printing or the like, but are formed in an area surrounded by the first graphic 120a and the second graphic 130a. As compared with the case where the ink is formed, etc., an ink reservoir or the like is less likely to be formed, and the dot collapse can be reduced or eliminated.

  In this embodiment, as described above, the first step of preparing the base material 111 and the base material 111 prepared in the first step are arranged along the first direction and spaced apart from each other. A second step of forming a first graphic pattern 120 composed of a plurality of first graphics 120a, a first direction on the substrate 111 on which the first graphic pattern 120 is formed in the second step, and A second graphic pattern 130 composed of a plurality of second graphics 130a extending in an intersecting second direction and arranged at intervals is used as a plurality of first graphics 120a and a plurality of second graphics. By forming the first graphic pattern 120 so as to intersect with the first graphic pattern 120, the dot pattern 105 is formed in which the area where the first graphic 120 and the second graphic 130 are not formed is the dot 105a. Third step , By performing, to form a dot pattern 105 which eliminate or reduce the collapse of the dot 105a.

  In particular, by forming the second graphic pattern 130 after the first graphic pattern 120 is dried, the first graphic pattern 120 and the second graphic pattern 130 can be overlapped so as to be in direct contact, I can clean it.

  In the above-described embodiment, the first graphic pattern 120 and the second graphic pattern 130 are provided so as to overlap each other, but the first graphic pattern 120, the second graphic pattern 130, May be formed simultaneously as one pattern. Even in such a case, since the dot 105a is formed in the area surrounded by the first graphic 120a and the second graphic 130a, the ink reservoir or the like is compared with the case where the dot is formed by direct printing or the like. Are less likely to form, and dot collapse can be reduced or eliminated. A plurality of first figures 120a extending along the first direction and arranged in parallel at intervals, and a plurality of first figures 120a extending along the second direction and arranged in parallel at intervals. By separately providing the second graphic 130a as in the above embodiment, the first graphic 120a and the second graphic 130a can be formed relatively accurately and neatly, so that the dot collapse is further reduced. It can be eliminated. Since the first figure 120a and the second figure 130a are formed in a straight strip and are arranged in parallel, it is easy to print the plurality of first figures 120a and the plurality of second figures 130a. is there.

  In the above-described embodiment, the dot pattern 105 has the above-described configuration, and the first direction and the second direction intersect with the direction in which the gradation changes to gradation, and the plurality of first figures 120a. Each of them is arranged along a first orthogonal direction orthogonal to the first direction, and becomes wider toward one end on the dark side of the gradation, and each of the plurality of second graphics is orthogonal to the second direction. Arranged along the second orthogonal direction, the width is thicker toward one end on the dark side of the gradation. As a result, the size of the dot 105a changes depending on the location, and a monochrome gradation is expressed. As described above, it is not formed directly by printing or the like, but is formed by an area surrounded by the first graphic 120a and the second graphic 130a. Therefore, compared with the case of forming dots by direct printing or the like, Ink reservoirs are not easily formed, and dot gradation can be reduced or eliminated, resulting in a beautiful gradation.

  Note that the dot pattern 105 does not have to represent gradation. In such a case, the width of the first graphic 120a may be constant and the width of the second graphic 130a may be constant. Further, gradation may be expressed by changing the width of either the first graphic 120a or the second graphic 130a.

  Note that the dot pattern 105 may be represented by a predetermined design other than the scale (for example, a frame line of an instrument panel, a number in an indicator portion, or the like).

  In the above-described embodiment, the first graphic 120a and the second graphic 130a are linear figures, and the widths thereof are continuously changed. It may be changed. This also represents a gradation. In addition, at least one of the contour of the first graphic 120a and the contour of the second graphic 130a may be a curved line instead of a straight line as in the above embodiment.

  In the above embodiment, the first graphic 120a and the second graphic 130a are black. However, other colors may be used, and the first graphic 120a and the second graphic 130a may be different colors. Also good. Further, the dot 105a may be set to another color by making the diffusion layer 112 other than white, or making the base 111 colored or transparent or not transparent. Further, for example, after the layer having the color of the dot 105a is formed on the base material 111 by printing or the like, the first graphic 120a and the second graphic 130a are formed on the base material 111 from above the layer. Good. In this case, the layer is exposed through a region where the first graphic 120a and the second graphic 130a are not formed, and the color of the dot 105a becomes the color of the layer. In this way, the color of the first graphic 120a, the color of the second graphic 130a, and the color of the dot 105a can be arbitrarily set. Forming the first graphic pattern 120 and the second graphic pattern 130 on the base material 111 (for example, forming the first graphic pattern 120 and the second graphic pattern 130 on a predetermined surface of the base material 111) As described above, the method also includes forming the first graphic pattern 120 and the second graphic pattern 130 on a predetermined layer formed on the substrate 111. That is, the first graphic pattern 120 and the second graphic pattern 130 are formed on the base material 111 (for example, the first graphic pattern 120 and the second graphic pattern 130 are formed on a predetermined surface of the base material 111). The process includes forming the first graphic pattern 120 and the second graphic pattern 130 via a predetermined object formed on the substrate 111.

  Although the base material 111 is a plate-like member in the above, it may be a plate-like member such as a casing of a predetermined apparatus. In addition, the first graphic 120 a and the second graphic 130 a may be formed on one back surface of the substrate 111. The first graphic 120 a and the second graphic 130 a are not limited to being formed on one surface of the base material 111, and may be formed on each of the front surface and the back surface of the base material 111. The first graphic 120a (first graphic pattern) and the second graphic 130a (second graphic pattern) intersect (overlapping) to represent the dots 105a and the dot pattern 105 when viewed from the viewer. do it.

  Further, gradation may be expressed by changing at least one of the pitch between the plurality of first graphics 120a and the pitch between the plurality of second graphics 130a.

  In the above-described embodiment, the plurality of first figures 120a and the plurality of second figures 130a are arranged so as to be parallel to each other (so that the center lines are parallel). , It does not have to be parallel.

  Any of the first direction and the second direction may be a direction along a curve such as a direction along at least a part of the circumference. For example, the first direction may be a plurality of circumferential directions of a plurality of concentric circles, and the second direction may be a plurality of directions extending radially from the center of the concentric circles (see FIG. 6; Part of the second direction is schematically depicted).

  The intersection angle between the first direction and the second direction, that is, the intersection angle between the first graphic 120a and the second graphic 130a (for example, the intersection angle between the center lines) is between 80 degrees and 100 degrees. It is desirable that This is because if the crossing angle is outside this range, the dot 105a becomes flat and the dot pattern 105 is not displayed neatly.

  At least one (preferably both) of the first direction and the second direction may be inclined approximately 45 degrees (including 45 degrees) with respect to the side constituting the end of the dot pattern. In FIG. 7A, when the first direction is set so as to be inclined approximately 45 degrees with respect to the horizontal direction in the figure (the first direction and the second direction (here, substantially orthogonal to the first direction) FIG. 7B shows a side (one side of the dot pattern) that constitutes the end of the dot pattern. When the first direction is inclined at approximately 45 degrees with respect to (here, since the second direction is substantially orthogonal to the first direction, the second direction is also approximately 45 degrees with respect to the side) The figure is tilted. As shown in FIG. 7, at least one (preferably both) of the first direction and the second direction is approximately 45 degrees (including 45 degrees) with respect to the side constituting the end of the dot pattern. If you tilt it, the edges of the dot pattern will not be rattled and look more beautiful than if you did not.

  In the dot pattern of FIG. 8, in the region A, the first direction and the second direction are inclined by approximately 45 degrees (including 45 degrees) with respect to the side constituting the edge of the dot pattern, In the region B, either the first direction or the second direction is not inclined at approximately 45 degrees (including 45 degrees) with respect to the side constituting the end of the dot pattern. In FIG. 8 as well, the first direction and the second direction are more inclined by about 45 degrees (including 45 degrees) than the side constituting the edge of the dot pattern than when the first direction and the second direction are inclined. The edges of the pattern do not rattle and look beautiful.

  Further, when dots are formed by direct printing or the like, the dots are particularly crushed when the printing method is screen printing. However, according to the present embodiment, the dot is crushed even by screen printing due to the above configuration or the like. Can be reduced or eliminated. Since screen printing can be carried out at a relatively low cost, the formation of the first graphic pattern and the second graphic pattern by screen printing can reduce or eliminate dot crushing at low cost.

  In the above embodiment, the instrument device 10 is mounted on a vehicle, but may be mounted on a vehicle other than the vehicle. Further, the dot pattern display body 100 may be applied other than the instrument panel.

  The present invention is not limited to the above-described embodiment and its modifications, and the above-described configuration can be changed as appropriate (for example, the shape of the component and the application can be changed).
