  Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof. FIG. 1 is a perspective view showing a configuration of a game ball according to the present invention. In the figure, reference numeral 1 denotes a sphere forming the main body of the game ball, which is formed from a steel metal material. At the equator position of the sphere 1, there is provided a marking portion 2 in which a character string made up of a plurality of characters, numbers or symbols is stamped in a concave shape. For example, in the example shown in the figure, the character string “-Nanotech-02 • 0003” is marked on the marking portion 2 in a line at the equator position of the sphere 1.

  FIG. 2 is a schematic diagram showing a configuration of a game ball according to the present invention, where (a) shows a case where the sphere 1 is seen from one direction, and (b) is a case where the sphere 1 is seen from the opposite direction. Is shown. The same character string is marked on one side and the opposite side of the sphere 1 in the marking portion 2 of the game ball according to the present invention. That is, the same character, number, symbol, or the like is marked on the marking portion 2 at a position facing the center of the sphere 1 in between. Therefore, in the example shown in the drawing, the character string of “-Nanotech-02 • 0003” is arranged in a row in the marking portion 2 in a manner of being repeatedly marked along the periphery of the sphere 1.

  FIG. 3 is a schematic diagram for explaining a method for forming the marking portion 2 of the game ball. The formation of the marking portion 2 of the game ball is performed using two marking materials 50 and 50. The marking material 50 is a so-called mold having a marking tooth portion 51 which is a convex portion (shape of mirror image) in which characters, numbers, symbols, or the like of a character string to be marked are inverted. When a plurality of characters, numbers, symbols, or the like are marked on the marking portion 2, convex portions such as inverted characters, numbers, symbols, etc. are arranged in a straight line on the marking tooth portion 51. Moreover, the shape of the marking tooth parts 51 and 51 provided in the two marking materials 50 and 50, respectively, is the same.

  The plain sphere 1 on which the marking portion 2 is not formed is sandwiched between the two marking materials 50 and 50 so that the respective marking tooth portions 51 and 51 come into contact with each other, and an equal force is applied to the two marking materials 50 and 50. Then, while pressing the sphere 1, the two marking materials 50, 50 are moved in the opposite direction in parallel (see the white arrow A in the figure). Thereby, the sphere 1 sandwiched between the marking materials 50 and 50 rotates in the direction of the arrow B in the figure, and at the surface of the sphere 1 on which the marking tooth portions 51 and 51 of the marking materials 50 and 50 are pressed, The marking part 2 which is the recessed part of the shape which reversed the marking tooth parts 51 and 51 is formed.

  At this time, in the case where a character string made up of a plurality of characters, numbers, symbols, or the like is marked on the marking portion 2, the shape of the characters, numbers, symbols, etc. The two engraving materials 50 and 50 are configured to move while simultaneously forming a concave portion having the same shape on the surface of the sphere 1. Therefore, the same characters, numbers, symbols, or the like of the character string are marked on the marking portion 2 at opposite positions with the center of the sphere 1 in between, as described above, thereby two marking materials 50 from both sides of the sphere 1. Since the pressing force applied to 50 becomes uniform, the marking portion 2 can be formed with high accuracy and at high speed. In addition, after forming the engraving portion 2, the character string may be colored by applying a paint such as white, yellow, or pink to the formed concave characters, numbers, or symbols.

  The character string to be marked on the marking part 2 of the game ball according to the present invention includes three kinds of character strings of “store name (provider name)”, “prefecture number (region number)” and “store number” in this order. It is the one that is lined up and marked. In the example shown in FIG. 1 and FIG. 2, “Nanotech” is marked as a “store name” indicating the name of a so-called pachinko store such as a provider (providing company) that provides pachinko games, for each prefecture in Japan. “02” is marked as the two-digit “prefecture number” attached, and it is managed or managed by the same provider, and identifies multiple stores that provide pachinko games in the same prefecture “0003” is marked as a four-digit “store number” for this purpose. Symbols such as “-” and “•” are for clarifying the separation of the three character strings, and may be other symbols or may be omitted.

  The “store name” marked on the stamp 2 is an arbitrary character string, and katakana, hiragana, numerals, alphabets, kanji, and the like can be arbitrarily combined. However, it is desirable not to use kanji with a complicated shape because the engraving may become unclear. In FIG. 1 and FIG. 2, “Nanotech” is marked as “Store name” in the stamped portion 2, for example, a game used in a store managed or managed by “Pachinko Nanotech” that provides pachinko games. It will be marked on the sphere. In addition, a mark, a symbol, a figure, or the like that can identify the provider as the “store name” may be marked on the marking unit 2.

  FIG. 4 is a chart showing an example of the prefecture number marked on the marking part 2 of the game ball according to the present invention. “Prefectural number” marked on the stamp 2 is a two-digit number. For example, Tokyo is associated with “01”, Osaka is associated with “02”, and Fukuoka is associated with “03”. ing. In this way, numbers 01 to 47 are associated with 47 prefectures in Japan. In the example shown in FIG. 1 and FIG. 2, since “02” is marked as “prefecture number” in the stamping part 2, it is determined that this game ball is used at a store located in Osaka. Can do.

  FIG. 5 is a chart showing an example of the store number marked on the marking part 2 of the game ball according to the present invention. The “store number” marked on the stamp 2 is a four-digit number, and for each combination of “store name” and “prefecture number”, the “store number” is associated with the store. In the example shown in the figure, the “store number” is “Nanotech” and the “prefecture number” is “02”, that is, the “store number”, that is, “the pachinko / nanotech” is operated in “Osaka”. "Store number" is shown as a list. For example, the central store in Osaka is associated with “0001”, the north store is associated with “0002”, the west store is associated with “0003”, and the east store is associated with “0004”. In this way, a store number is assigned to each store managed by “Pachinko Nanotech” in “Osaka”. In the example shown in FIG. 1 and FIG. 2, “0003” is marked as the store number in the stamping part 2, so this game ball is used in “West store” operated by “Pachinko Nanotech” in “Osaka”. Can be determined.

Another example of a character string to be marked on the stamped portion 2 is shown below.
(1) -Yyukyukyo-01 ・ 0001
(2) ☆ BBB ☆ 03 ・ 0012
(3) ・ MMM ・ 04 ・ 0004
(4) ☆ YH ☆ 05 ・ 0005
(1) is an example of an inscription stamped on a game ball used in the first store managed by “Yukyu Kyo” in “Tokyo”. Further, (2) is an example of an inscription stamped on a game ball used in a twelfth store managed by “BBB” in “Fukuoka”. Since (3) and (4) are the same, description thereof is omitted.

  In addition, for example, in a game ball manufacturing company, it is possible to manage the prefectures to which game balls are delivered based on the “prefecture number” stamped on the stamped part 2, and to set the “store name” and “store number”. Based on this, it is possible to manage the store to which the game balls are delivered. In this case, the correspondence between the “store name”, “store number” and “prefecture number” as shown in FIGS. 4 and 5 and the pachinko game provider, store name, and prefecture name is stored in advance in the computer as a database. Let me. For example, the manager of the manufacturing company inputs the “store name”, “store number”, and “prefecture number” stamped on the stamped part 2 of the defective game ball or the illegally used game ball into the computer. Then, the computer identifies the store where the game ball was used based on the stored database, and outputs the identification result to the manager. There are stores that provide a large number of pachinko games in the whole country, but it is possible to specify a store that used a game ball simply by storing a simple database in the computer. Furthermore, by storing the date of delivery of game balls and the number of deliveries in a computer, it becomes possible to manage information related to game balls in more detail.

  In the game sphere having the above configuration, the store using the game sphere can be identified by examining the character string written in the stamped portion 2. Therefore, for example, game balls brought in from other stores and used illegally, or nonstandard game balls can be monitored at each store. It is also possible to automatically eliminate these game balls by installing a function for identifying the character string of the stamped portion 2 on the pachinko machine. Moreover, since a store can be specified when a game ball is dumped illegally, this can be suppressed.

  In the present embodiment, three character strings of “store name”, “prefecture number”, and “store number” are marked on the stamped portion 2 of the game ball. However, the present invention is not limited to this. For example, another character string may be engraved, such as a production lot number. Further, when a store exists only in one prefecture, the “prefecture number” may be omitted. Further, instead of assigning a number to each prefecture, a number may be assigned to each municipality, or a number may be assigned to other regions. Further, the “prefecture number” is 2 digits and the “store number” is 4 digits. However, the present invention is not limited to this, and any number of digits may be used. Moreover, when forming the marking part 2, it was set as the structure which moves the two marking materials 50 and 50 to the direction of arrow A, respectively, However, it is not restricted to this, One marking material 50 is fixed and the other Only the marking material 50 may be moved.

(Modification 1)
The game ball according to Modification 1 has a configuration in which the marking portion 2 is colored differently for each game ball. FIG. 6 is a chart showing a coloring example of the marking part 2 of the game ball according to the modification 1 of the present invention, and (a) is a case where the marking part 2 is colored with a different color for each manufacturing year of the gaming ball. (B) is a case where the marking part 2 is colored with a different color for each game ball manufacturing factory. For example, in the case of FIG. 6A, if the marking portion 2 of the game ball is colored blue, it is manufactured in 2005, and if it is colored green, it is manufactured in 2006. If it is colored yellow, it can be determined that it was manufactured in 2007. Further, in the case of FIG. 6B, if the stamped portion 2 of the game ball is colored blue, it is manufactured at the Osaka factory, and if it is colored green, it is manufactured at the Hyogo factory. If it is colored yellow, it can be determined that it was manufactured at the Fukuoka Factory.

  Therefore, since the information such as the manufacturing year or the manufacturing factory of the game ball can be acquired from the color of the marking portion 2 of the game ball, it is possible to search for the cause when a failure occurs. In the example shown in FIG. 6, the coloring is different depending on the year of manufacture or the manufacturing factory of the game ball. However, the present invention is not limited to this. For example, the coloring may be different for each lot. It is good also as a structure which performs different coloring according to these conditions.

(Modification 2)
FIG. 7 is a schematic diagram showing a configuration of a game ball according to Modification 2 of the present invention. FIG. 7A shows a case where the sphere 1 is viewed from one direction, and FIG. 7B shows the sphere 1 in the opposite direction. The case seen from FIG. In the engraved part 2 of the game ball according to the modified example 2, a character string “-Nanotech-” is marked on one side of the sphere 1 and a character string “02 · 0003” is marked on the opposite side. . Thus, it is good also as a structure which writes a different character string in the one side and the opposite side of the spherical body 1. FIG. Even in this case, since “Store Name” is marked on one side and “Prefectural Number” and “Store Number” are marked on the opposite side, the game is similar to the game ball shown in FIG. It is possible to uniquely identify the store that used the ball.
