Description

  This device arranges seven pieces at predetermined positions, and displays numbers 0 to 9 with the predetermined pieces of the seven pieces set in different colors on the front and back sides facing the front. By doing so, the present invention relates to a number display that displays at least one digit.

  For example, when a sports competition such as basketball or tennis is performed at a school or a playground, in order to display a score conventionally, a plurality of pieces of numbers “0” to “9” are individually displayed on the surface. Prepare a number plate and a sign for displaying a specific number by suspending these number plates in an aligned state, and the numbers necessary to display the score as the competition progresses are displayed. Appropriately selected number plates are sequentially suspended from the display. For example, in a basketball game, if the score is 45 to 30, four number plates each representing the numbers “4”, “5”, “3”, and “0” are selected and hung on the display tools. Be held.

  In addition, in gasoline stations, etc., the price of gasoline per liter is displayed at the store so that the driver who is driving can easily recognize the price of gasoline. The price of gasoline on the day is displayed using the number plate and the display tool.

  However, in the method of displaying a specific number using the above-described number plate, it is necessary to prepare number plates of “0” to “9” for each digit, so that the number of number plates increases. Therefore, it is necessary to manage a large number of number plates, and there are problems that the management becomes complicated and the number plates are easily lost. Also, when changing the number to be displayed, it is necessary to suspend each number plate from the display tool and then suspend the other number plates from the display tool, which makes the work complicated. In view of this, various numbers have been proposed as number display tools that can display numbers such as the scores and prices described above and can easily change the displayed numbers (see, for example, Patent Document 1). ).

JP-A-8-54831

  As shown in FIG. 7, the number display tool described in Patent Document 1 includes seven segments 100 a to 100 g that can display numbers from “0” to “9”, and arrangement portions of the segments 100 a to 100 g. And a display substrate 101 on which openings 102a to 102g corresponding to the outer shapes of the segments are formed. Each of the segments 100a to 100g is a plate-like body having a line-symmetric outer shape, and the front and back surfaces have different colors (for example, the front surface is “white” and the back surface is the same as the front surface of the display substrate 101). Is colored. In addition, each of the segments 100a to 100g is provided with two rotation shafts 103 facing outward at the center in the length direction. Both end portions of each rotating shaft 103 are supported by bearings (not shown) provided on the display substrate 101, so that the segments 100 a to 100 g can rotate around the rotating shaft 103.

  In order to display a predetermined number, for example, the number “4”, among the segments 100a to 100g, the segments 100a, 100c, 100d, and 100g constituting the number “4” have a white colored surface. While facing the front, the other segments 100b, 100e, and 100f are manually reversed so that the black colored back faces the front and a predetermined number is displayed.

  However, in the number display tool having the above-described configuration, a desired number can be appropriately displayed by simply pressing and reversing one of the segments, but a hole forming process for forming the openings 102a to 102g in the display substrate 101 is possible. In addition, it is necessary to provide a structure for enabling rotation of each of the segments 100a to 100g. Therefore, there is a problem that the manufacturing is troublesome and the manufacturing cost is high and expensive. In addition, when a plurality of types of numerical indicators having different numbers are manufactured by changing the size of each segment 100a to 100g, an opening corresponding to the size of each segment 100a to 100g is provided for each type. Since it is necessary to create the display substrate 101 provided with the parts 102a to 102g, it is troublesome.

  The present invention has been made by paying attention to the above-described problems, and an object thereof is to provide a number display tool that can be easily changed at a low cost while easily changing the number to be displayed.

  The number display device according to the present invention is composed of three pieces equally arranged in three upper and lower stages and four pieces respectively arranged at both side positions between the pieces, so that one number 8 is formed. By setting the front and back surfaces of each piece to different colors and displaying a number from 0 to 9 with a predetermined piece of the seven pieces facing the table, at least one digit is displayed. The above-mentioned seven plate-like pieces for each number whose front and back surfaces are magnetized, the guide plate with at least the back surface magnetized, and the magnetized surfaces of each piece and the guide plate are magnetically attracted. And a display substrate having a flat display surface. The display surface of the display substrate is set to the same hue as the back surface of each piece, and is divided into display areas for each digit by a guide plate, and the guide plate forms an 8-character outline. And a positioning side in contact with the outer edge of the predetermined piece.

  In the number display tool having the above-described configuration, the number 8 is formed on the display surface of the display substrate by arranging seven pieces for each number of digits at predetermined positions. Each piece has its back side set to the same color as the color set on the display surface of the display board, and the front side is set to a color different from the color set on the display surface of the display board. In response, a predetermined piece is selected and turned to the front, and the other pieces are turned to the back, so that a desired number is displayed.

  Each piece is magnetized on both the front and back sides, and each piece is held on the display surface of the display substrate regardless of whether the front or back surface is directed to the front by magnetic adsorption. There is no need to perform troublesome processing such as forming or turning each piece, and a numeric display can be manufactured easily and inexpensively. Also, if you want to change the size of each piece to produce multiple types of number display tools with different displayed numbers, you only need to change the size of the display board for each type. The production of the display board does not take much time.

  Furthermore, on the display surface of the display substrate, a guide plate having a positioning side for each digit is arranged, and the outer edges of the predetermined pieces constituting the figure 8 shape are brought into contact with the positioning side, respectively. Positioning of each piece is easy, and the outline of the figure 8 is kept in order by the positioning side. Thereby, since each piece is stably held at a predetermined position, it is possible to prevent each piece from being displaced.

   It should be noted that if the display surface of the display substrate is formed to a size capable of forming one of the eight characters, a size capable of forming one digit number and two of the eight characters side by side. If formed, two-digit numbers can be displayed respectively. Furthermore, if the display surface of the display substrate is formed to have a size that allows three or more of the above eight characters to be formed side by side, it is possible to display a number of three or more digits.

  In a preferred embodiment of the present invention, all the pieces have the same shape, and an intermediate portion having a predetermined width and both ends of the tapered shape are integrally formed. According to this embodiment, since all the pieces have the same shape, all the pieces need only be manufactured by the same manufacturing method, so that the manufacturing of the pieces is not troublesome and the parts management is easy.

  In a preferred embodiment of the present invention, the guide plate is composed of four plate-like plate members each having a vertical piece and a horizontal piece, and is formed on the outer edge of the piece at the four corners of the figure 8 outline. Each is provided with a right-angled positioning side that touches. According to this embodiment, when preparing a plurality of types of number display devices having different numbers of displayed numbers by changing the size of each piece, each plate material can also be used. There is no need to prepare a guide plate for each type.

  In another preferred embodiment of the present invention, the guide plate is constituted by a single plate member having a rectangular hole, and the plate member makes one round in contact with the outer edge of the piece on the entire circumference of the figure 8 outline. A positioning edge is provided. According to this embodiment, since the outline of the figure 8 is kept perfectly and does not collapse by the positioning edge that goes around the plate, each piece is held in a state where it does not move to a predetermined position. Therefore, each piece is not displaced, and the displayed number is not deformed at all.

  In a further preferred embodiment of the present invention, the guide plate has a thickness larger than each piece. According to this embodiment, each piece does not get over the guide plate, and each piece can be held in a more stable state at a predetermined position.

  According to this device, both the front and back surfaces of each piece are magnetized, and each piece is stably held on the display surface of the display substrate by magnetic attraction, regardless of whether the front surface or the back surface is directed to the front. Thus, unlike the conventional example, there is no need to perform troublesome processing such as forming an opening in the display substrate or making each piece rotatable, and a numeric display can be manufactured easily and inexpensively. In addition, the positioning edge of the guide plate arranged on the display surface of the display substrate maintains the contour of the figure 8 formed by each piece, so that positioning of each piece is easy and each piece is predetermined. It can be held in a stable state at a predetermined position.

  The number display device according to the present invention can display numbers from 0 to 9, and as shown in FIGS. 1 and 2, the numbers from “0” to “9” are displayed in units of one digit. 7 pieces 1a to 1g for the display, a display substrate 2 having a display surface 20 on which the pieces 1a to 1g are arranged in a plane, and a guide plate 3 disposed on the display surface 20 of the display substrate 2 Has been.

By being arranged vertically at both side positions, the number “8” character 4 is formed on the display surface 20 of the display substrate 2. Each of the pieces 1a to 1g is a flat plate having the same shape, and the outer shapes thereof are formed in line symmetry. Thereby, when each piece 1a-1g is reversed, it will come to the original position. In this embodiment, each of the pieces 1a to 1g is formed by integrally forming an intermediate portion 10 having a predetermined width and both ends 11 and 11 having a tapered shape. It is arranged in the state without.

  The pieces 1a to 1g have different colors on the front surface and the back surface (in this embodiment, the front surface is “white” and the back surface is the same “green” as the color set on the display surface 20 of the display substrate 2 described later). Is set to Among the seven pieces 1a to 1g, for example, as shown in FIG. 1 and FIG. 2, the numbers of the pieces 1c to 1g are directed by facing the front side, and the other pieces 1a and 1b are directed to the back side by facing the numbers. “3” can be displayed. Similarly, the back side of the piece 1c is directed to the front side, and the other pieces 1a, 1b, and 1d to 1g are directed to the front side. it can.

  FIG. 3 shows the structure of each piece 1a-1g. Each piece 1a to 1g has a thickness of about 1 mm, and the cover sheets 13A and 13B made of a synthetic resin sheet such as vinyl chloride are bonded to the front and back surfaces of the thin magnetized plate 12 with an adhesive. Is formed. The surface of one cover sheet 13A is colored white, and the surface of the other cover sheet 13B is colored green.

  The magnetized plate 12 has magnetized surfaces 14 formed on both sides thereof. Each magnetized surface 14 is configured with a strip-shaped magnetic pole array in which, for example, the N and S polarities are alternately reversed. This magnetized plate 12 is made of a permanent magnet material powder such as ferrite magnet powder, which is a raw material, and an elastic material such as rubber or elastic plastic, and then rolled into a thin plate shape, which is attached to both surfaces of the thin plate material. The magnetized surface 14 is formed by applying a magnetic treatment.

  As shown in FIGS. 1 and 2, the display substrate 2 is formed by bonding a magnetic plate 22 such as an iron plate to the surface of a base 21 made of, for example, a synthetic resin plate having a flat rectangular shape. One of the magnetized surfaces 14 on the front and back surfaces of the seven pieces 1a to 1g and the magnetized surface on the back surface of the guide plate 3 to be described later are magnetically attracted to the flat display surface 20 of the surface of the magnetic plate 22. Retained.

  The display surface 20 of the display substrate 2 is set to the same hue (“green” in this embodiment) as the back surfaces of the pieces 1a to 1g. In addition, if the hue of the display surface 20 of the display board 2 and the color of the back surface of each piece 1a-1g are the same, it does not need to be the same to lightness and saturation. Further, in this embodiment, the display surface 20 of the display substrate 2 has a size that allows each piece 1a to 1g to be arranged at a predetermined position to form one number “8” 4. Thus, it is possible to display a one-digit number.

  As shown in FIG. 4, if the display surface 20 of the display substrate 2 is formed to a size that allows the two “8” characters 4 to be formed side by side, a two-digit number can be displayed. Although not shown, if the display surface 20 of the display substrate 2 is formed to a size that can form three or more of the “8” characters 4 side by side, it is a three or more digit number. Can also be displayed.

  On the display surface 20 of the display substrate 2, for each digit, for example, one digit is displayed as in the embodiment of FIGS. 1 and 2, it corresponds to one digit. In the case of displaying a two-digit number as in the embodiment of FIG. 4, the guide plate 3 is arranged corresponding to each of the two numbers. The guide plate 3 is constituted by four plate members 30 having a horizontal shape 31 and a vertical piece 32 and having a bowl shape in plan view. By disposing each plate member 30 at the four corners of the outline of the “8” character 4 so as to follow the outline of the “8” character 4, the display surface 20 of the display substrate 2 is moved by the guide plate 3. It is divided into a display area 20A for each digit.

  Each plate 30 has a thickness (about 4 mm) larger than each piece 1a to 1g, and includes a magnetized surface 42 that is magnetically attracted by the display surface 20 of the display substrate 2 on the back surface. This plate member 30 is formed by joining two magnetized plates (not shown) with an adhesive to form an L shape, and then attaching a surface material (not shown) such as vinyl tape to the entire surface except the back surface. Is formed. The vinyl tape is preferably of a color having the same hue as the color set on the display surface 20 of the display substrate 2 (it is not necessary to have the same brightness and saturation). Things are used. Thereby, the number displayed on the display surface 20 of the display substrate 2 can be shown more clearly.

Each magnetized plate constituting the plate material 30 is made into a plate shape by kneading a permanent magnet material powder such as ferrite magnet powder as a raw material and an elastic material such as rubber or elastic plastic, and is rolled into a plate shape. The magnetized surface 42 is formed by magnetizing one surface.
The plate member 30 is not limited to the structure as in this embodiment, and may be configured with a single magnetized plate formed in an L shape.

  Each plate 30 has a positioning side 36 at the end face along the inner edge forming a right angle. The positioning sides 36 of the plate members 30 are in contact with the outer edges of the six pieces 1a to 1f constituting the outline of the "8" character 4 at the four corners of the outline of the "8" character 4, respectively. Due to the positioning side 36, the outline of the character 4 of “8” is kept in an orderly manner between the plate members 30. As described above, when the outline of the character 4 is maintained, the pieces 1a to 1g are held in a stable state at predetermined positions, so that the pieces 1a to 1g are displaced. Can be prevented.

  FIG. 5 shows another embodiment of the guide plate 3. The guide plate 3 in the illustrated example is composed of four plate members 37 having a rectangular planar shape. Each plate member 37 has a thickness (about 4 mm) larger than each piece 1a to 1g, and is a plate-like magnetized plate magnetized so that the back surface is magnetically attracted to the display surface 20 of the display substrate 2 (see FIG. (Not shown) is formed by attaching a green vinyl tape (not shown) to the entire surface except the back surface. In each plate member 37, an end surface along one side edge constitutes a positioning side 38, and the positioning side 38 abuts against the outer edges of the six pieces 1 a to 1 f constituting the outline of the “8” character 4. Are arranged as follows. Thus, the outline of the character 4 of “8” is maintained.

  FIG. 6 shows still another embodiment of the guide plate 3. The guide plate 3 in the illustrated example is constituted by a single plate member 39 having a rectangular hole 40. The plate member 39 has a thickness (about 4 mm) larger than the pieces 1a to 1g, and a magnetized plate (not shown) magnetized so that the back surface is magnetically attracted to the display surface 20 of the display substrate 2. In addition, a green vinyl tape (not shown) is attached to the entire surface except the back surface. The hole 40 of the plate member 39 is formed in a size that the outline of the “8” character 4 fits, and each piece 1a to 1g fits in the hole 40 in a state of forming the “8” character 4. ing. The peripheral edge of the hole 40 of the plate material 39 constitutes a positioning side 41 that goes around. In a state where the pieces 1 a to 1 g are fitted in the hole 40, the positioning side 41 has an outline of the character 4 of “8”. It abuts on the outer edges of the six pieces 1a to 1f constituting the same.

  In order to display numbers using the number display tool shown in FIGS. 1 to 4, first, all pieces 1 a to 1 g are arranged at predetermined positions on the display surface 2 of the display substrate 2, and the number “8” is displayed. "4" is formed.
