Description

The present invention relates to a method of manufacturing a gaming machine including an obstacle nail maintenance step of performing different types of maintenance on a plurality of obstacle nails provided on a game board of the gaming machine .

  In a pachinko game machine that plays a game by driving a game ball into a game area, a large number of obstacle nails are set in the game area on the game board surface. For example, brass nails or the like are used as such obstacle nails, and are nailed on a game board surface by a nail driver or the like at the time of manufacturing the game board.

  When the nail is driven into the game board by the nailing machine in this way, an error may occur in the angle or the like of the obstacle nail with respect to the game board. Since such an error has a large effect on the winning rate of the game ball, etc., at the time of manufacturing, an image of an obstacle nail placed on the game board is taken, and the set point of the obstacle nail is set based on the image data thus taken. In some cases, maintenance such as measurement of the amount of bending or deviation from the head and correction of the measured amount of bending or deviation is performed. In addition, such maintenance of obstacle nails is not only during the production of the game board, but also collects the pachinko machine used in the game hall, and the angle of the obstacle nail to the game board surface changes due to the impact of the game ball. In some cases, a used game board that has been used up is refurbished for reuse.

  As described above, as a device for maintaining the amount of bending or deviation of an obstruction nail placed on the game board surface, for example, a concave hole of an engagement shaft provided in a manipulator head operated based on a command of a control device. There has been a device in which a head of an obstruction nail is fitted and a bending or displacement is corrected by operating a manipulator (for example, see Patent Document 1).

  These obstacle nails 200 are made of, for example, a brass material, and as shown in FIG. 3B, have a cylindrical body 200a (also referred to as a main body) having a diameter φ1 of about 1.85 mm (φ1 = about 1.85 mm). ) And a spherical head 200b (also referred to as a nail cap) having a diameter Sφ2 formed at one end of the body 200a of about 4.2 mm (Sφ2 = about 4.2 mm). The obstacle nail 200 is erected on the game board surface 2a by being driven into a hole 2d formed in advance on the game board surface 2a by a nailing machine 16, which will be described later. The length L1 up to the portion 200b is about 16.8 mm (L1 = about 16.8 mm). A screw groove 200c is formed on the other end of the body 200a. The screw groove 200c prevents the obstacle nail 200 from falling off the game board 2 due to a frictional force generated between the body 200a inserted into the hole 2d and the inner peripheral surface of the hole 2d.

  As shown in FIG. 9A, the hole 2d for placing the obstacle nail 200 has a predetermined angle θ1 (θ1) directed upward with respect to a Z axis (perpendicular line) perpendicular to the game board surface 2a. (= Approximately 4 degrees). Therefore, the obstacle nail 200 is also erected with the head 200b side inclined upward by about 4 degrees with respect to the Z axis (perpendicular line), so that the game ball P colliding with the obstacle nail 200 moves to the game board 2 side as much as possible. I try to bounce.

  As shown in FIG. 3 (B), for example, the distance L2 on the base side of the torso 200a of the left and right obstacle nails 200 constituting the designated nail 204 is about 10.5 mm (L2 = about 10.5 mm). Since the distance L3 on the tip side is about 12 mm (L3 = about 12 mm), the distance between the left and right trunks 200a gradually increases from the game board surface 2a toward the head 200b. The diameter Sφ of the game ball P is about 11 mm (for example, Sφ = about 11 mm), and the game ball P passes between the body portions 200a of the left and right obstacle nails 200 in contact with the game board surface 2a. Can be done.

  In this embodiment, the distance L2 is about 10.5 mm, and the distance L3 is about 12 mm of the designated nail 204. However, the present invention is not limited to this. The dimensions can be variously changed according to the gauge configuration of the game board 2 (so-called nail arrangement) and the like. Also, the separation dimensions of the other designated nails 205 to 208 can be individually set to values different from those of the designated nail 204 (for example, 11.5 mm as described later).

  Returning to FIG. 1, at the lowermost part of the game area 10, there is provided an out port 11 for taking in a game ball that has not entered any winning port. Speakers 8L and 8R for reproducing and outputting sound effects and the like are provided at upper left and right positions of the gaming machine frame 3, and effect LEDs 9 are provided around the gaming area 10. At the lower right position of the gaming machine frame 3, a hit ball operation handle (operation knob) operated by a player or the like to fire a game ball as a game medium toward the game area 10 is provided.

Is provided with an upper plate 90 (hit ball supply plate) which is held (retained) in the upper plate 90. A lower plate 91 is provided below the gaming machine frame 3 for holding (reserving) excess balls overflowing from the upper plate 90 so as to be able to be discharged to the outside of the pachinko gaming machine 1. The tilting operation of the stick controller 31A attached to the member forming the lower plate 91 is detected by a controller sensor unit (not shown), and is pressed against the push button 31B provided on the member forming the upper plate 90. The operation is detected by a push sensor (not shown).

  Next, a circuit configuration of the pachinko gaming machine 1 will be described. On the back of the pachinko gaming machine 1, for example, a main board (not shown), an effect control board, an audio control board, an LED control board, and a relay for relaying various control signals transmitted between the main board and the effect control board. Various boards such as a board, a payout control board, an information terminal board, a launch control board, and an interface board are arranged.

  The main board (not shown) is a control board on the main side, on which various circuits for controlling the progress of the game in the pachinko gaming machine 1 are mounted. The main board is mainly a sub-side control board including a function of setting a random number used in a special figure game, a function of inputting a signal from a switch or the like disposed at a predetermined position, and a production control board (not shown). It has a function of outputting a control command, which is an example of command information, as a control signal and transmitting it to the address, a function of outputting various information to a hall management computer, and the like. In addition, the main board performs lighting / extinguishing control of each LED (for example, a segment LED) constituting the first special symbol display 4A and the second special symbol display 4B, so that the first special symbol and the second special symbol are displayed. Controlling the fluctuation display of a predetermined display symbol, such as controlling the fluctuation display and controlling the fluctuation of the normal symbol by the normal symbol display 20 by controlling lighting / turning off / coloring of the normal symbol display 20 and the like. It also has a function to do. In addition, various circuits such as a game control microcomputer (not shown), a switch circuit (not shown), and a solenoid circuit are mounted on the main board.

  The main board is connected with wiring for transmitting detection signals from a gate switch for detecting a game ball passing through the passage gate 41, a first starting port switch, a second starting port switch, and a count switch. In addition, display control of the first special symbol display 4A, the second special symbol display 4B, the ordinary symbol display 20, the first reservation display 25A, the second reservation display 25B, the general picture reservation display 25C and the like is performed. For transmitting a command signal for connection.

  The control command transmitted from the main board to the effect control board via the relay board is, for example, an effect control command transmitted and received as an electric signal. The effect control command includes, for example, a fluctuation pattern designation command indicating a fluctuation pattern indicating a fluctuation mode such as a fluctuation time of an effect symbol, a type of a reach effect, and the presence or absence of a pseudo run.

  The game control microcomputer mounted on the main board is, for example, a one-chip microcomputer, and includes a ROM (ReadOnlyMemory) for storing a game control program and fixed data, and a RAM for providing a game control work area. (RandomAccessMemory102), a CPU (Central Processing Unit) that executes a game control program to perform a control operation, a random number circuit that updates numerical data indicating a random value independently of the CPU, and an I / O (Input / Outputport). As an example, in the game control microcomputer, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by the CPU executing the program read from the ROM.

  The effect control board (not shown) is a sub-side control board independent of the main board, receives a control signal transmitted from the main board via the relay board, and displays the effect display device 5, the speakers 8L and 8R. In addition, various circuits for controlling the production operation by the production electric components such as various motors, solenoids, sensors, and light emitting diodes (LEDs) provided in the production LED 9 and other production units are mounted.

  An effect control board (not shown) includes an effect control CPU for performing a control operation according to a program, a ROM for storing an effect control program and fixed data, a RAM for providing a work area for the effect control CPU, A display control unit that executes processing for determining the control content of the display operation in the effect display device 5, a random number circuit that updates numerical data indicating a random number value independently of the effect control CPU, O is mounted. As an example, in the effect control board, the effect control CPU executes the effect control program read from the ROM to execute a process for controlling the effect operation by the effect electric components. In addition, the ROM stores various data tables and the like used for controlling the rendering operation, in addition to the rendering control program.

  Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko gaming machine 1, based on the fact that the game ball has passed through the passing gate 41 provided in the gaming area 10, the ordinary symbol display on the ordinary symbol display 20 is started. After starting the fluctuation of the normal symbol, the predetermined time that is the normal symbol fluctuation time elapses, and if the normal symbol other than the symbol per normal symbol is stopped and displayed, the normal symbol fluctuation display result is `` Normal symbol loss '' Become. When a specific ordinary symbol (a symbol per ordinary symbol) is stopped and displayed, the fluctuation display result of the ordinary symbol becomes "an ordinary symbol", and the enlarged opening control (tilt control) of the ordinary variable winning prize ball device 6B is performed. When the time elapses, the normal opening control that returns to the vertical position is performed.

  After the first starting condition is established due to the game ball winning the first starting winning opening or the like, based on the fact that the first starting condition is established due to, for example, the end of the last special map game or big hitting game state. Then, the special figure game using the first special symbol display 4A is started. In addition, after the second starting condition is established due to the game ball winning the second starting winning opening or the like, the second starting condition is established due to, for example, the end of the last special map game or the big hit game state. Based on this, the special figure game using the second special symbol display 4B is started.

  In the special figure game, after the variable display of the special symbol is started, when the variable display time elapses, the determined special symbol (special figure display result) is derived and displayed. At this time, if a specific special symbol (big hit symbol) is stopped and displayed, the result is a "big hit" as a specific display result, and if a special symbol different from the big hit symbol is stopped and displayed, "miss". After the fluctuation display result in the special figure game becomes “big hit”, the game is controlled to a big hit game state as a specific game state in which a round (also called “round game”) advantageous to the player is executed a predetermined number of times.

  In the big hit game state, the special winning prize opening door of the special variable prize ball device 7 has a predetermined upper limit time (for example, 29 seconds or 0.1 second) or a predetermined number (for example, 9) of prize balls. During the period until the event occurs, the special winning opening is kept open. As a result, a round in which the special variable winning ball device 7 is placed in the first state (open state) which is advantageous for the player is executed.

  The special winning opening door that has the special winning opening opened during the execution of the round receives game balls falling on the surface of the game board 2 and then closes the special winning opening, thereby providing a special variable winning ball device. 7 is changed to a second state (closed state) disadvantageous to the player, and one round is ended. The round, which is the opening cycle of the special winning opening, can be repeatedly executed until the number of executions reaches a predetermined upper limit number (for example, “16”).

  In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, the variation display of the effect symbols is started in response to the start of the special figure game. Then, during the period from the start of the variable display of the effect symbol to the end of the variable display, the variable display state of the effect symbol may reach a predetermined reach state. The reach state is a display in which the effect symbols stopped and displayed in the display area of the effect display device 5 constitute a part of the big hit combination, and the effect symbols which are not yet stopped and displayed are continuously changing. A state or a display state in which all or a part of the effect symbols are synchronously fluctuating while forming all or a part of the jackpot combination.

  As a fixed special symbol in the special figure game, a fixed effect symbol that is a predetermined normal big hit combination (also referred to as a “non-probable variable big hit combination”) of a plurality of types of big hit combinations is stopped and displayed, and the fluctuation display result is “non-probable variable big hit”. , The state is controlled to the big hit state, and after that, the time reduction control (time reduction control) is performed. By performing the time saving control, the fluctuation display time (special figure fluctuation time) of the special symbol in the special figure game is shortened as compared with the normal state. In the time-saving control, a so-called electric chew support, in which the winning frequency of the ordinary symbol is increased and the winning frequency of the ordinary variable winning ball apparatus 6B is increased. In the time-saving control, a predetermined number of times (for example, 100 times) of the special figure game is executed after the end of the big hit game state, and one of the conditions that the variable display result is “big hit” is satisfied first. Sometimes, it should be finished.

  As a confirmed special symbol in the special figure game, a determined effect symbol that is a predetermined probability variable jackpot combination (also referred to as a “variable probability jackpot combination”) among a plurality of types of jackpot combinations is stopped and displayed, and the variable display result is “probability variable jackpot”. If it does, it is controlled to the big hit state, and after that, the probability variation control (probable variation control) is performed together with the time saving control. By performing the certainty change control, the probability that the change display result is “big hit” in each special figure game is improved so as to be higher than that in the normal state. Probable change control is performed when the change display result becomes "big hit" and the condition of controlling the game to the big hit game state is satisfied after the big hit game state ends, and the predetermined number of times (e.g. When the special map game is executed, the probability change control is ended by the probability change lottery executed each time the special map game is started after the big hit game state is ended, and "determinate change has fall" is determined. It may end at time, etc.

  When the time reduction control is performed, the control for reducing the variation time of the ordinary symbol (the ordinary symbol variation time) in the ordinary symbol game is shorter than that in the normal state, and the variation display result of the ordinary symbol in each ordinary symbol game is changed to “ The control for improving the probability of "hit" than in the normal state, and the tilt control time for performing the tilt control of the movable wing piece in the ordinary variable prize ball device 6B based on the fact that the variable display result is "common figure hit", The game ball can easily pass (enter) the second start winning opening, such as control to make it longer than in the normal state and control to increase the number of tilts than in the normal state, and the second start condition can be satisfied. Controls (electric power support control, high opening control) that are advantageous to the player by increasing the performance are performed. As a result, the second starting condition for executing the special figure game using the second special figure is easily satisfied, and the special figure game can be frequently executed. The time until it becomes shorter.

  Next, an operation (action) of the pachinko gaming machine 1 in the present embodiment will be described. In the main board (not shown), when power supply from a predetermined power supply board is started, a game control microcomputer (not shown) is activated, and a CPU (not shown) performs a predetermined process as a game control main process.

  In the special symbol process, the CPU first determines whether there is a first start winning or a second starting winning. If there is a winning, the special figure display result determination, the big hit type determination, the variation pattern Random number values for determination and the like are respectively extracted, and a start winning process is executed in which the random number value is stored at the highest level of an empty entry in the first special figure holding storage device or the second special figure holding storage device.

  Further, the CPU determines whether or not to start the special figure game based on the presence / absence of the reserved data stored in the first special figure reserved storage device or the second special figure reserved storage device, Based on the numerical data indicating the random number value for determination, a special (predetermined) whether or not to make the fluctuation display result of the special symbol or the effect symbol a “big hit” before the fluctuation display result is derived and displayed. The symbol normal processing is executed. In other words, when starting the variation display of the special figure game, the CPU determines whether to derive and display the big hit display result as the display result of the variation display based on the random number value stored when the start winning is generated. The process of determining (lottery) is executed.

  Next, a variation pattern setting process for determining the variation pattern to be one of a plurality of types, a special symbol variation process for performing a setting for varying the special symbol and a process for measuring an elapsed time after the special symbol starts to vary, A special symbol stop process is performed to stop the change of the special symbol and to perform a setting for stopping and displaying (derived) the fixed special symbol. If the result of the fluctuation display is "big hit", a big hit opening pre-process, a big hit opening process, a big hit opening process, and a big hit ending process for opening / closing the big win in the big hit game state are performed.

  Next, the operation of the effect control board (not shown) will be described. First, when power is turned on, the effect control CPU starts executing the main process. When a timer interrupt occurs in the main processing, command analysis processing, effect control process processing, and effect random number update processing are executed.

  In the effect control process process, the hold display updating process for updating the hold storage display in the first hold storage display area 5D and the second hold storage display area 5U of the effect display device 5 to a display corresponding to the storage content of the hold storage buffer. Execute Next, in accordance with the value of the effect control process flag, a fluctuation pattern designation command reception waiting process for confirming whether or not a variation pattern designation command has been received from the game control microcomputer, so that the variation of the effect symbol is started. The control of the switching timing and the like of each variation state (variation speed) constituting the variation pattern according to the process data set in the effect symbol variation start process, the variation symbol process, and the end of the variation time are monitored. Processing during effect design fluctuation, which performs display control of effect display device 5, sound output from speakers 8L and 8R, light emission of effect LED 9 and drive control of effect unit (not shown), stops fluctuation of effect symbol and display result An effect symbol fluctuation stop process for performing control for deriving and displaying (stop symbol) is performed.

  In the big hit display processing, after the end of the fluctuation time, control is performed to display a screen for notifying the effect display device 5 of the occurrence of the big hit. In the big hit game processing, control during the big hit game is performed. In the big hit end effect process, the effect display device 5 performs display control for notifying the player that the big hit game state has ended.

In the manufacturing line 12, in the nailing (step S3), the first maintenance (step S5), the second maintenance (step S7), etc., which will be described later, the nailing by the nailing machine 16 and the maintenance by the obstacle nail maintenance device 300 are performed. Failure may occur.

  In the manufacturing line 12, the supply-side transfer device 13 and the discharge-side transfer device 13 are arranged in parallel, and each nailing machine 16 and each obstacle nail maintenance device 300 are supplied by the robot arm device described above. The game board 2 is arbitrarily taken out from the transfer device 13 on the side of the machine, and is driven or maintained, and thereafter, the game board 2 that has been driven or maintained is returned to the transfer device 13 on the discharge side. Since it is not determined beforehand whether nail maintenance or nailing is performed by the device, the storage history of each game board 2 is stored in the storage device 505, so that the device involved in the production of each game board 2 can be specified. Like that. When the maintenance history information is accumulated, it becomes possible to identify which of the various devices has a large number of maintenance deficiencies. Therefore, the maintenance work of a plurality of devices installed on the manufacturing line 12 can be performed. It is said that it can be easily performed.

  In addition, by storing the maintenance history of each game board 2 in the storage device 505, if a failure of an obstacle nail is found after the final stage of the manufacturing process or after delivery, the maintenance history of the game board 2 is referred to and the game board is referred to. 2 can be identified, that is, a device having a possibility of malfunction can be specified, so that a new game board 2 is not maintained by the device having a possibility of malfunction. As described above, it is possible to cope with the situation at an early stage, such as immediately stopping the driving of the apparatus and performing a maintenance operation.

  Further, in step S2, the seal 15 on which the two-dimensional code 15a is printed is placed below the board 2A (for example, a position where it is not exposed from the outside when it is mounted on the pachinko gaming machine 1; in this embodiment, a lower right position). (See FIG. 2). In addition, a reading camera provided at a predetermined position of the manufacturing line 12 (for example, each nail driving machine 16, each obstacle nail maintenance device 300, the first nail inspection device 17A, the second nail inspection device 17B) is provided on the seal 15. In addition to the two-dimensional code 15a read by the printer, the print date 15g, model code 15b, serial number 15c, gauge number 15d, cell number 15e, bar code information 15f, etc. They are indicated by numerals, symbols, etc. (see FIG. 17).

  In the present embodiment, since the order in which the game board 2 is transported to the first two-dimensional code marking device 14a via the step S1 is not changed in the transport, the game is played in the first two-dimensional code marking device 14a. Although it is not necessary to specify the type of the board 2, the present invention is not limited to this. In the step S1, a one-dimensional code or the like capable of specifying a serial number is pasted on the game board 2 in advance. The type of the game board 2 may be specified based on the serial number specified from the one-dimensional code in the first two-dimensional code marking device 14a.

  In this embodiment, the seal 15 on which the two-dimensional code 15a is printed is attached to the board 2A, and the two-dimensional code 15a can be read by a reading camera (reading device). The present invention is not limited to this, and it is very good that a sticker including an IC chip storing the above-mentioned various information is attached and the information stored in the IC chip can be read by a predetermined reading device.

  When the marking operation of the two-dimensional code 15a is completed on the board 2A, a plurality of obstacle nails 200 are driven into the prepared holes by the nailing machine 16 into the prepared holes processed in the step S1 (step S3). When the nailing machine 16 completes the driving operation of the nail 200, the data of the two-dimensional code 15a read by the reading camera and the temperature and humidity at the time of the operation are displayed together with the device number of the nailing machine 16. The information is transmitted to the management computer 500 as nailing work completion data. Then, the first nail inspection device 17A takes images of the obstacle nails 200 driven into the game board surface 2a by a plurality of cameras 44 described later (see FIG. 16), and based on the captured image data, each obstacle nail 200 A nail image inspection for inspecting the inclination (the position coordinates of the position of the head 200b) with respect to the Z-axis direction orthogonal to the game board surface 2a, the presence or absence of the obstacle nail 200, nail bending, rust, discoloration, etc. is performed (step S4). When the inspection is completed, the first nail inspection device 17A transmits the primary inspection result data to the management computer 500 together with the device number of the first nail inspection device 17A and the read data of the two-dimensional code 15a of the game board 2.

  The management computer 500 (CPU 502) that has received the primary inspection result data, based on the received primary inspection result data, causes each of the obstacle nails 200 to incline about 4 degrees upward in the Z-axis direction orthogonal to the game board surface 2a. It is determined whether or not there is a displacement from the set position of the head 200b of each obstacle nail 200 specified from the gauge data corresponding to the game board 2 in the XY axis direction and the amount of displacement. The set position (coordinate position) of the head 200b of each obstacle nail 200 is a position at which the head 200b is arranged when the obstacle nail 200 is accurately driven into the pilot hole, and corresponds to the type of the game board 2. It is stored in the storage device 505 of the management computer 500 as gauge data.

  Also, an allowable range (accuracy) is set for each set position in consideration of an error in the XY axis directions. When the head 200b is located outside the allowable range, it is determined that the head 200b is abnormal (defective). At the same time, the direction and amount of deviation from the set position are specified. The allowable range can be set to a desired value for each nail 200 as described later (see FIGS. 18 and 19).

  The management computer 500 (CPU 502), which has received the primary inspection result data, finds out that among the obstacle nails 200 driven in step S3, the deviation in the XY axis direction from the set position of the head 200b is out of the allowable range by the inspection in step S4. With respect to the obstacle nail 200 determined to be present, first maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the set position is created, and the first maintenance data is received. The two-dimensional code 15a included in the inspection result data is stored in association with the serial number 15c in the read data. In addition, the first maintenance data is read data including the serial number 15c from the obstacle nail maintenance device 300 that has taken out the game board 2 to which the seal of the two-dimensional code 15a of the serial number 15c has been attached from the transport device 13. Is transmitted (replyed) to the obstacle nail maintenance device 300, and maintenance based on the first maintenance data is instructed.

  In the obstacle nail maintenance device 300, based on the first maintenance data received from the management computer 500, the first maintenance is performed on the obstacle nail 200 in which the abnormality is detected in the step S4 (step S5). When the first maintenance is completed, the first maintenance completion data including the read data of the two-dimensional code 15a and the temperature / humidity information at the time of execution of the first maintenance is stored in the management computer 500 together with the device number of the obstacle nail maintenance device 300. Is transmitted to the management computer 500, and information regarding the first maintenance such as the completion of the first maintenance and the device number and the temperature and humidity information of the obstacle nail maintenance device 300 that has performed the first maintenance is transmitted. .

  For each of the obstacles 200 after the first maintenance, whether or not each obstacle 200 is inclined upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a is determined with respect to the set position of the head 200b. A first inspection is performed based on the direction and the amount of positional deviation in the XY axis direction, and the inspection result of the first inspection reads the device number of the obstacle nail maintenance device 300 and the two-dimensional code 15a. The data is transmitted to the management computer 500 as first inspection completion data together with the data. Note that, in the present embodiment, these first inspections are performed by the obstacle nail maintenance device 300 using the inspection tool 600, similarly to the second inspection described below, but the present invention is not limited to this. Instead, these first inspections may be performed by the second nail inspection device 17B.

  In the present embodiment, the first maintenance completion data and the first inspection completion data are individually transmitted to the management computer 500. However, the present invention is not limited to this. May be transmitted at the same time when the process is completed.

  The first maintenance (S5) and the first inspection (S6) are repeated until all the heads 200b of the obstacle nail 200 after the first maintenance are arranged within the allowable range of the set position (S6 +). However, since the nail 200 placed within the allowable range by the first maintenance is removed from the target of the first maintenance again, as the first maintenance is repeatedly performed, the nail to be repaired is removed. The number of 200 will gradually decrease.

  At the time of these repeated maintenance, the first maintenance data is created again in the management computer 500 based on the inspection result of the first inspection, and nail maintenance is executed based on the created first maintenance data. You. The first maintenance completion data is also transmitted to the management computer 500 every time the first maintenance is repeatedly performed.

  It should be noted that the maintenance contents based on the first maintenance data created by the management computer 500 are to be sequentially different according to the number of times (the number of inspection NGs) determined not to be within the allowable range in the first inspection. Is set. Specifically, as shown in FIG. 6, when the number of times of the inspection NG is the first time, in principle, the maintenance amount (deformation amount) of the obstacle nail 200 determined to be the inspection NG is determined to be the inspection NG. The maintenance content is changed to a maintenance amount (deformation amount) different from the maintenance amount (deformation amount) in the first maintenance before the maintenance. When the number of times of the inspection NG is the second time, in principle, the maintenance content is changed to a tool different from the tool used for the maintenance of the obstacle nail 200 determined as the inspection NG. When the number of times of the inspection NG is the third time, in principle, the maintenance content is changed to the obstacle nail maintenance device 300 different from the obstacle nail maintenance device 300 used for the maintenance of the obstacle nail 200 determined as the inspection NG. You. That is, when the first maintenance in which the tool corresponding to the second inspection NG is changed is performed, the obstacle nail maintenance device 300 that has performed the first maintenance performs the obstacle nail 200 that has performed the first maintenance. The game board 2 having the above is loaded into the transport device 13 by the robot arm device, and the first maintenance is performed by another obstacle nail maintenance device 300 that is taken out of the loaded game board 2 from the transport device 13 by the robot arm device. Be executed. Then, when it is determined that the inspection is NG in the first inspection after the first maintenance is performed by the other obstacle nail maintenance device 300, the gaming board 2 is set as a discharge target from the production line. You. Specifically, in the obstacle nail maintenance device 300 determined as the inspection NG, the obstacle is discharged out of the production line by the robot arm device.

  In other words, the management computer 500 according to the present embodiment, when there is a failure nail 200 of the inspection NG in the first inspection, as shown in FIG. Transmits first maintenance data for performing different repairs.

  In the present embodiment, in the first maintenance, the maintenance is performed only for the nail 200 in which an abnormality is detected in the nail image inspection in the step S4, but the present invention is not limited to this. Instead, the first maintenance may be performed for all the nails 200 regardless of the presence or absence of the abnormality.

  When it is determined in the first inspection that there is no obstacle NG of the inspection NG (N in S6 +), the game board 2 is returned to the transport device 13 by the robot arm device. Then, the game board 2 returned to the transport device 13 is taken out of the transport device 13 by the robot arm device of another obstacle nail maintenance device 300, and designated in advance according to the type of the game board 2 among a plurality of obstacle nails. A second maintenance is performed for placing the head 200b of the obstacle nail 200 (for example, the designated nails 204 to 208) within the allowable range of the designated position. That is, for the obstacle nail maintenance device 300 that has taken out the game board 2 that has completed the first inspection from the transport device 13, the management computer 500 uses the obstacle nail specified in advance according to the type of the game board 2 among the plurality of obstacle nails. For the target 200 (for example, the designated nails 204 to 208), the second maintenance data for arranging the head 200b of the obstacle 200 within the allowable range of the designated position is transmitted to instruct the execution of the second maintenance. I do. The obstacle nail maintenance device 300 that has received the second maintenance data performs the second maintenance for the designated nails 204 to 208 based on the received second maintenance data (step S7).

  As described above, in the present embodiment, by performing the second maintenance in the obstacle nail maintenance device 300 different from the obstacle nail maintenance device 300 that has performed the first maintenance, the bias of the maintenance accuracy due to the difference in the obstacle nail maintenance device 300 is reduced. Although it is possible to prevent this, the present invention is not limited to this, and the first maintenance and the second maintenance may be performed by the same obstacle nail maintenance device 300.

  Specifically, the second maintenance is, for example, gradually widened from the base side to the head 200b side so that the interval between the pair of obstacle nails 200 in each of the designated nails 204 to 208 becomes a desired dimension (FIG. 3B). And FIG. 9B), the head 200b is arranged at a designated position different from the set position. In addition, it also includes maintenance for changing the inclination angle, the inclination direction of each obstacle nail 200, the arrangement mode with other obstacle nails 200, and the like, regardless of whether the maintenance was performed in the first maintenance of the process S5. Done.

  Also, an allowable range (accuracy) is set for each specified position in consideration of an error in the XY axis directions. When the head 200b is located outside the allowable range, it is determined that there is an abnormality and the specified The direction and amount of deviation from the position are specified. The allowable range can be set to a desired value for each nail 200 as described later (see FIGS. 18 and 19).

  These designated nails 204 to 208 relate to the probability of entry of a game ball into each of the winning ports and the passing gate 41 related to the provision of a game value, among a plurality of obstacle nails 200 driven into the game board surface 2a. It is a nail that is highly likely to affect the base value of the pachinko gaming machine 1 due to a slight error or deviation. In addition, the inclination angle and the inclination direction of each obstacle nail 200 and the manner of disposition with other obstacle nails 200 change according to the type of the game board 2. As described later, the designated nail 200 can designate a desired obstacle nail 200 for each game board 2 (see FIG. 20).

  As described above, the first maintenance is performed on the obstacle nail 200 for which the abnormality is detected in the step S4 among the plurality of obstacle nails 200 driven into the game board surface 2a in the step S3. The second maintenance includes the operation of placing the head 200b within the allowable range of the set position, while the second maintenance targets a predetermined designated obstacle nail (for example, the designated nails 204 to 208). The operation includes arranging the head 200b of the obstructed nail 200 within the allowable range of the designated position. That is, in the second maintenance and the step S7 of performing the second maintenance, maintenance different in content from the first maintenance and the step S5 of performing the first maintenance is performed.

  In addition, the second maintenance is a uniform or difficult maintenance in the nailing process by the nailing machine 16 and requires delicate work with higher precision than the first maintenance. By performing the maintenance separately from the first maintenance for the object 200, the maintenance work of the obstacle nail 200 can be performed efficiently. In the case of the game board 2 of the type requiring no second maintenance for the designated nails 204 to 208, the second maintenance in the step S7 may be omitted.

  Then, after performing the second maintenance for the designated nails 204 to 208 for the obstacle nail 200, the final inspection (step S9) by the second nail inspection device 17B using the inspection tool 600 described later is performed. In the method, a second inspection is performed to determine whether or not the obstacle nails 200 of the designated nails 204 to 208 are located within the allowable range of the designated position. The second inspection and the second maintenance are repeatedly performed until the head 200b of the obstacle nail 200 after the second maintenance is located within the allowable range of the designated position (S8 +). However, since the obstacle nail 200 placed within the allowable range by the second maintenance is removed from the target of the second maintenance again, as the second maintenance is repeatedly executed, the obstacle nail to be repaired is performed. The number of 200 will gradually decrease.

  Note that, in the present embodiment, these second inspections are performed by the obstacle nail maintenance device 300 using the inspection tool 600 similarly to the first inspection, but the present invention is not limited to this. The second inspection may be performed by the second nail inspection device 17B.

  At the time of these repeated maintenance, the second maintenance data is created again in the management computer 500 based on the inspection result of the second inspection, and the nail maintenance is executed based on the created second maintenance data. . The second maintenance completion data is also transmitted to the management computer 500 every time the second maintenance is repeatedly performed.

  It should be noted that the maintenance contents based on the second maintenance data created by the management computer 500 are to be sequentially different according to the number of times (the number of inspection NGs) determined not to be within the allowable range in the second inspection. Is set. That is, maintenance of different contents is performed according to the same rules as the first maintenance described above. Specifically, as shown in FIG. 6, when the number of inspection NGs is the first time, the maintenance content is changed in principle to the maintenance amount (deformation amount), and when the number of inspection NGs is the second time, In principle, the maintenance content is changed to a different tool, and when the number of inspection NGs is the third, the maintenance content is changed to a different obstacle nail maintenance device 300 in principle, and the number of inspection NGs is the fourth. Are set as discharge targets and discharged outside the production line.

  In other words, the management computer 500 according to the present embodiment, when there is a failure nail 200 of the inspection NG in the second inspection, as shown in FIG. Transmits the second maintenance data for performing different repairs.

  As described above, when the second maintenance and the second inspection for the designated nails 204 to 208 have been completed, the obstacle nail maintenance device 300 that has performed the second maintenance, together with the device number, sends a message to the reading camera. The second maintenance completion data including the read data of the two-dimensional code 15a, the temperature and humidity information at the time of executing the second maintenance and the second inspection, and the inspection result information of the second inspection (the second inspection result information) is managed. By transmitting the information to the computer 500, the management computer 500 completes the second maintenance and the second inspection, and inspects the device number, the temperature and humidity information of the obstacle nail maintenance device 300 that has performed the second maintenance, and the second inspection. The information about the second maintenance such as the result information is transmitted.

  When it is determined in the second inspection that there is no obstacle NG of the inspection NG (N in S8 +), the gaming board 2 on which the second inspection has been performed is transferred by the robot arm device to the transfer device 13 on the discharge side. It is thrown and transported to the second nail inspection device 17B, and the second nail inspection device 17B performs a final inspection on all the obstacle nails 200 as to whether or not the head 200b of each obstacle nail 200 is at the set position. (Step S9). In the present embodiment, in step S9, the positions of all the obstacle nails 200 on the game board 2 are inspected, but the present invention is not limited to this, and only the designated nails 204 to 208 are used. The inspection may be performed. Further, the game board 2 in which the abnormality is detected in the step S9 is taken out of the production line 12, and is again repaired by the obstacle nail maintenance device 300 or the like different from the production line 12, and also when the repair is completed. Then, the second maintenance completion data is transmitted to the management computer 500 from the nail maintenance apparatus 300 that has performed the repair.

  If there is no abnormality in the final inspection by the second nail inspection device 17B, the work of mounting the guide rail 2b and the windmill 61 using the prepared hole formed in the game board surface 2a is performed (step S10). Then, after attaching other gaming members such as the center decorative frame 51 and various prize devices, it is assembled to the gaming machine frame 3 of the pachinko gaming machine 1 (step S11). Finally, the completed pachinko gaming machine 1 is packed and shipped (step S12).

  In the following, for convenience of explanation, the obstacle nail maintenance device 300 will not be described with reference to the vertical and horizontal directions of the pachinko gaming machine 1, but will be described with reference to the vertical and horizontal directions of FIGS. Also, the gaming board 2 is placed horizontally with the upper side in a state of being assembled to the pachinko gaming machine 1 facing forward in FIGS. 7 and 8.

  As shown in FIGS. 7 and 8, the obstacle nail maintenance device 300 according to the present embodiment includes a maintenance arm 301 for maintaining the obstacle nail 200 and the game board 2 on which the obstacle nail 200 to be maintained is driven. And a table 302 mounted horizontally. The obstacle nail maintenance device 300 includes a robot arm device and the like for taking out and inserting the game board 2 from the transport device 13 as described above. In the following description, these robot arm devices and the like will be described. The omitted nail straightening device will be described as an obstacle nail maintenance device 300.

  The maintenance arm 301 includes a base 310 placed on a floor, a turntable 312 provided to be rotatable around a rotation axis T1 that is perpendicular to the base 310, and a turntable 312. The first arm 313 is provided so as to be rotatable about a rotation axis T2 that is oriented horizontally, and the tip of the first arm 313 is provided so as to be rotatable about a rotation axis T3 that is oriented horizontally. A second arm 314, a third arm 315 rotatably provided at a front end of the second arm 314 via a horizontally-oriented rotation axis T <b> 4, and a turn in a horizontal direction at a tip of the third arm 315. A fourth arm 316 rotatably provided around the dynamic axis T5, a head 317 provided at the tip of the fourth arm 316 to which a maintenance tool 400 described later can be attached, and a maintenance tool attached to the head 317 400 and It has to.

  As described above, the maintenance arm 301 including the multi-joint arm is connected to the management computer 500 described above, and is built in the base 310 and each arm based on a command from the management computer 500 (CPU 502). When a driving source (not shown) such as a motor is driven, the maintenance tool 400 moves the maintenance tool 400 in a horizontal direction (front-rear, left-right direction, XY-axis direction) along the game board surface 2a or in a vertical direction (up and down) perpendicular to the game board surface 2a. (Direction, Z-axis direction) or tilt with respect to the Z-axis.

  In the present embodiment, the maintenance arm 301, which is an example of an operation unit for operating the maintenance tool 400, is configured by an articulated arm. However, the present invention is not limited to this. The tool 400 may be configured by a manipulator other than the articulated arm as long as it can move the tool 400 in the XY-axis direction or the Z-axis direction or tilt the tool 400 with respect to the Z-axis.

  On the upper surface of the table 302, guide pins that can be inserted into respective guide holes formed at predetermined positions of the game board 2 (in this embodiment, four places around the game board 2) are provided upright. The game board 2 is placed on the table 302 by a robot arm device (not shown) so that the guide pins are inserted into the guide holes. A slide clamp 330 is provided at one side edge of the table 302 so as to be movable in the left-right direction of the table 302 and can push the game board 2 placed on the table 302 to the left. As shown in FIG. 8, when the slide clamp 330 pushes the game board 2 placed on the table 302 to the left, the guide pin inserted into the guide hole hits the right side surface of the guide hole. The contact makes it possible to suppress the occurrence of displacement due to the gap (play) between the guide hole and the guide pin.

  As shown in FIG. 8, on the upper surface of the table 302, a mounting portion for mounting a detection pin G for detecting a positional deviation is provided at a front right corner position. The detection pin G mounted on the mounting portion has a constricted portion at the center, and is configured to be easily broken when the upper portion is moved back and forth, right and left, and has a slightly larger diameter than the detection pin G. The maintenance tool 400 is replaced with a position deviation confirmation tool 400 ′ having a proper insertion hole, and the position deviation confirmation tool 400 ′ is vertically moved by the maintenance arm 301 in accordance with the position of the mounting portion where the detection pin G is mounted. When the position is not displaced, the detection pin G is not broken, but when the position is displaced, the detection pin G is broken and the position is shifted. Can be easily recognized. If a position shift has occurred, a predetermined correction process is performed to correct the position shift.

  As shown in FIG. 8, a pair of elevating clamps 320 movably provided in the front-rear direction by a slide mechanism 340 are provided on both side edges of the upper portion of the table 302. The game board 2 is held on the table 302 by holding the game board 2 from above the obstacle nail 200 and holding the game board 2 on the table 302 with the game board surface 2a facing upward so that the obstacle nail 200 faces upward. , Can be fixed.

  As shown in FIG. 8, the lifting clamp 320 of this embodiment is formed of a substantially U-shaped transparent resin plate having a gap formed in the center, and the obstacle nail 200 to be repaired is The elevating clamp 320 is sequentially moved so as to be located immediately below the gap, and the nail close to the obstacle nail 200 to be maintained is held down by the elevating clamp 320 to fix the game board 2, thereby causing a displacement in the maintenance. In addition, the maintenance status of the nail 200 to be repaired can be visually recognized through the transparent lifting / lowering clamp 320 even if the vicinity of the nail 200 to be repaired is pressed.

  As shown in FIG. 7, the maintenance tool 400 includes a rod-shaped part 401 made of a metal rod-shaped member having a diameter φ10 of about 6 mm (φ10 = about 6 mm), and a metal material attached to the lower end of the rod-shaped part 401. 12, the upper end of the rod-shaped portion 401 can be exchangeably attached to the head 317, and there are a plurality of types having different shapes of the holding portion 403 (FIG. 12). As shown in FIG. 8, around the base 310, a predetermined number is exchangeably prepared in advance.

  As a mode of holding and fixing the game board 2 by the lifting clamp 320 in the obstacle nail maintenance device 300 of the present embodiment, a clamp control pattern A shown in FIG. 10A and a clamp control pattern B shown in FIG. Is set, and the control unit 300 ′ controls the position and the pressing pressure of the lifting / lowering clamp 320 based on the set clamp control pattern.

  As shown in FIG. 10 (A), the clamp control pattern A positions the obstacle 200 to be maintained in a substantially U-shaped gap of one of the lifting / lowering clamps 320 and moves the position of the other lifting / lowering clamp 320 forward and backward. This is a clamp control pattern that is arranged at a symmetrical position with respect to the center position in the direction, and controls the game board 2 to be held and fixed with a lower pressure (small force) than the clamp control pattern B.

  As shown in FIG. 10B, the clamp control pattern B applies a higher pressure (larger) to the game board 2 than the clamp control pattern A in a state where both lifting clamps 320 are arranged at the center position in the front-rear direction. This is a clamp control pattern that controls to hold, fix, and hold with force. In the clamp control pattern B, when the lifting nail 320 is placed at the center position in the front-rear direction and the obstacle nail 200 to be repaired is covered by the lifting clamp 320, Is moved to a position where it is not covered by the lifting clamp 320, and the game board 2 is held and fixed.

  In the present embodiment, each of these clamp control patterns is selected according to the maintenance content, as shown in FIG.

  Specifically, when the nail 200 to be repaired is the designated nail 204 to 208, the clamp control pattern B is selected (see FIG. 10B), and the nail 200 to be repaired is designated as the nail 204 to 208. If the obstacle nail 200 is other than the nail 208, the clamp control pattern A is selected (see FIG. 10A).

  In the case where the tool type is the maintenance tool 400 of the tool type A used for maintaining only one obstacle nail 200 in a cylindrical shape in the maintenance, the clamp control pattern A is selected. In the case of the maintenance tool 400 of tool types B and C used for simultaneously maintaining the obstacle nail 200 of the above, the clamp control pattern B is selected.

  In addition, when the variation amount (maintenance amount) in maintenance is equal to or greater than a predetermined threshold value, the clamp control pattern B is selected. When the variation amount (maintenance amount) is less than the threshold value, the clamp control pattern B is selected. Pattern A is selected.

  Note that the relationship between the maintenance content and the clamp control pattern is in principle, and the clamp control pattern B has priority. That is, when the maintenance content includes the maintenance content corresponding to the clamp control pattern B, for example, even if the maintenance content is other than the designated nails 204 to 208 and the maintenance is performed by the tool type A, the variation amount When the (maintenance amount) is equal to or larger than the threshold, the clamp control pattern B is selected.

  As described above, in the present embodiment, the contents of the maintenance include a difference in the type of the nail 200 to be repaired, a difference in the type of the maintenance tool 400 used for the maintenance, and a difference in the amount of fluctuation (the amount of maintenance) in the maintenance. Therefore, the game board 2 can be suitably held, and a plurality of types of maintenance having different maintenance contents can be appropriately performed.

  Next, a description will be given of a maintenance tool 400 used for maintenance in the obstacle nail maintenance device 300. As shown in FIG. 12, there are a plurality of types of maintenance tools 400 having different shapes of the holding portion 403.

  Specifically, the maintenance tools 400 are roughly classified into three types according to the number of obstacle nails 200 to be simultaneously maintained. The tool type A is a maintenance tool 400 used to service only one obstacle nail 200, and the tool type B is a maintenance tool used to service two obstacle nails 200 at the same time. The tool type C is a maintenance tool 400 used for simultaneously servicing the three obstacle nails 200.

  Further, as illustrated in A-1 to A-4 in FIG. 12, there are a plurality of types of the maintenance tools 400 of the tool type A depending on the shape of the distal end portion, the size of the opening, and the like. These tool types A are mainly used for maintenance of guide nails 201L and 201R called continuous nails.

In addition, as illustrated in B-1 to B-4 in FIG.
There are a plurality of types depending on the width and shape of the groove into which the obstacle nail 200 formed in the holding portion 403 is inserted, the thickness of the holding portion 403, and the like. These tool types B are mainly used for maintenance of obstacle nails 200 facing the winning opening called life nails such as designated nails 204 to 208.

  The maintenance tool 400 of the tool type C is a maintenance tool 400 mainly used for maintenance of the designated nail 205. In the present embodiment, an example in which the tool type C is set to two types is illustrated. However, the present invention is not limited to this. Various types may be provided depending on the width and shape of the groove into which the nail 200 is inserted, the thickness of the holding portion 403, and the like.

  28 to 30 show a detailed shape of a typical maintenance tool 400 among the maintenance tools 400 used in the present embodiment. 28 to 30 include a hexahedral view, a cross-sectional view, a reference perspective view, and a use state reference perspective view of the maintenance tool.

  An example of these maintenance tools 400 will be described. For example, as shown in FIG. 9, the maintenance tool 400 of the tool type B-1 has a holding portion 403 for holding the body 200a in a substantially rectangular shape in front view. Are formed on the left and right sides of the front surface, and concave grooves 411L and 411R having left and right dimensions that are wider than the diameter φ1 (outer diameter) of the body 200a are formed in the vertical direction. A bar-shaped portion 401 is connected to the center of the upper surface of the holding portion 403 in the left-right direction, and the holding portion 403 is provided so as to be substantially orthogonal to the bar-shaped portion 401.

  Further, left and right side corners on the rear side of the holding portion 403, inner side corners of the upper and lower openings of the concave grooves 411L and 411R, outer side corners of the lower opening of the concave grooves 411L and 411R, and lower surfaces of the holding portion 403. The left and right side corners are chamfered.

  By performing the chamfering process on the corners of each side as described above, the nail 200 and the game board surface 2a may be damaged when the body portion 200a is nipped by the holding portion 403 and the maintenance work is performed. Has been prevented.

  The obstacle nail maintenance device 300 configured as described above includes the step S4 of the plurality of obstacle nails 200 that have been driven into the game board surface 2a using the maintenance tool 400 in the step S5 in the manufacturing process of the game board 2 described above. The first maintenance is performed based on the first maintenance data, and the second maintenance is performed based on the second maintenance data. The specified nails 204 to 208 are designated in advance in step S7. Do.

  Next, the contents of the second maintenance of the designated nails 204 to 208 performed by the obstacle nail maintenance device 300 in step S7 will be described with reference to FIGS. 9 and 13 to 15. In the following, the second maintenance content of the designated nail 204 will be described as an example, and the second maintenance content of the other designated nails 205 to 208 will be the same, so the description will be omitted.

  As shown in FIG. 9, the left and right obstacle nails 200, which are the designated nails 204, are driven by the nailing machine 16, and the left and right obstacle nails 200 move in the Z-axis direction orthogonal to the game board surface 2 a. It is inclined about 4 degrees upward. In the set position, the distance L2 on the base end side and the distance L3 on the head 200b side of the body 200a of each of the left and right obstacle nails 200 are the same, approximately 10.5 mm (L2 = approximately 10.5 mm, L3 = About 10.5 mm). That is, the left and right obstacle nails 200 are driven so that the body portions 200a thereof are substantially parallel to each other. In the second maintenance, the distance between the obstacles 200 on the left and right of the designated nail 204 is gradually increased from the base side toward the head 200b side, and the head 200b is arranged at a designated position where the separation dimension L3 is about 12 mm. This is done based on the data.

  Based on the second maintenance data received from the management computer 500, the obstacle nail maintenance device 300 operates the holding portion 403 of the maintenance arm 301 by a drive source (not shown) to perform maintenance of the designated nail 204.

  The second maintenance data is based on the humidity / temperature data obtained from the hygrometer / thermometer by the management computer 500 when the designated nail 204 of the game board 2 is maintained. If the material is a plywood board, it includes the plywood board operating pattern data for calculating the moisture content of the plywood board and operating the holding portion 403 of the maintenance arm 301 based on the moisture content. As described above, the designated nails 204 of the plywood game board 2 can be maintained in accordance with changes in the indoor environment (humidity / temperature) in the factory, so that the plywood boards can be prevented from being damaged during the maintenance work of the designated nails 204. , Maintenance accuracy is increased.

  In addition, a plurality of types of maintenance tools 400 having a size and a shape corresponding to the type of the game board 2 and the target obstacle nail 200 are prepared as the maintenance tool 400. It can be exchanged accordingly. The operation of selecting and replacing the maintenance tool 400 is included in the second maintenance data, and the maintenance arm 301 automatically performs the operation according to the nail 200 to be maintained. May be replaced manually.

  The obstacle nail maintenance device 300 drives the maintenance arm 301 in a predetermined operation pattern based on the received second maintenance data, and moves the holding portion 403 from the initial drive position to the arrangement position of the designated nail 204 to be maintained. The holding portion 403 is moved above the game board 2 so as not to contact the obstacle nail 200.

  Next, as shown in FIG. 9A, the holding portion 403 is lowered to the front side of the designated nail 204 such that the openings of the concave grooves 411L and 411R face the designated nail 204 side. Then, as shown in the direction of the white arrow in FIG. 9A, the holding portion 403 is moved rearward, and the body portions 200a of the left and right obstacle nails 200 are fitted into the concave grooves 411L and 411R, respectively. Place at one position. As a result, the trunks 200a of the left and right obstacle nails 200 are clamped by the concave grooves 411L and 411R. In the holding portion 403, at this predetermined position, as shown in FIG. 9A, the rod-shaped portion 401 is inclined upward by a predetermined angle (about 4 degrees) with respect to the Z axis (perpendicular line).

  At the first position, as shown in FIG. 9A, the lower surface of the holding portion 403 is separated from the game board surface 2a, and the separation dimension L4 is about 2.5 mm (L10 = 2.5 mm). That is, the holding portion 403 is arranged at a position closer to the game board surface 2a than the head portion 200b of the body portion 200a on the base side. Further, the bar-shaped portion 401 is arranged in a state of being inclined at a predetermined angle θ1 (θ1 = 4 degrees) upward with respect to the Z axis (perpendicular line) so as to be parallel to the body portion 200a of the obstacle nail 200. The vertical dimension L5 of the pinching portion 403 is shorter than the length L1 from the game board surface 2a to the head 200b of the obstacle nail 200 (L5 <L1). Since the holding portion 403 is separated from the head 200b, the holding portion 403 can be slid toward the head 200b.

  Next, as shown in FIG. 9 (B), the holding portion 403 is divided into a plurality of times while swinging the bar-shaped portion 401 left and right by a predetermined angle with respect to a center position CP in the left-right direction on the lower surface of the holding portion 403. Move to

  Specifically, the bar-shaped portion 401 is inclined rightward by a predetermined angle θ2 (θ2 = approximately 13.15 degrees) with respect to the center position CP in the left-right direction on the lower surface of the sandwiching portion 403. In this state, the operation is stopped for a predetermined period (for example, about 0.6 seconds). Next, the clamping unit 403 is moved from the first position in a direction inclined upward by about 4 degrees with respect to the Z-axis direction by a first movement amount (for example, about 0.35 mm) and arranged at the second position. As shown in FIG. 9 (B), after the holding portion 403 is tilted by a predetermined angle θ2 (θ2 = approximately 13.15 degrees) toward the left side of the bar-shaped portion 401 with respect to the center position CP, and returned to the Z axis, It is inclined at a predetermined angle θ3 (θ3 = approximately 12.25 degrees) toward the left side, and the operation is stopped for a predetermined period (for example, about 0.6 seconds) in the inclined state.

  In this way, the oblique nail 200 on the side in which the bar-shaped portion 401 swings becomes larger in bending angle than the obstruction nail 200 on the other side by tilting the holding portion 403 in the left-right direction with respect to the center position CP. By repeating a plurality of times, the interval between the obstacles 200 of the designated nail 204 is gradually increased from the base toward the head 200b. By such a second maintenance, the head 200b of each of the designated nails 204 is arranged within the allowable range of the designated position.

  Next, the obstacle nail maintenance device 300 performs a second inspection for determining whether or not the head 200b of the designated nail 204 having undergone the second maintenance is located within an allowable range of the designated position. In this second inspection, in addition to whether or not the head 200b of the second repaired obstacle nail 200 is located within the allowable range of the designated position, the bending of the trunk 200a of the obstacle nail 200 is normal. It is determined whether or not.

  In this second inspection, the obstacle nail maintenance device 300 first replaces the maintenance tool 400 with the inspection tool 600 shown in FIG. The inspection tool 600 includes a rod-shaped part 601 made of a metal rod-shaped member having a diameter φ10 of about 6 mm (φ10 = about 6 mm), and a measuring part 602 made of a metal material attached to the lower end of the rod-shaped part 601. It is mainly composed. The measurement unit 602 has a base 602a fixedly installed on the lower end side of the rod 601 and a moving unit 602b provided to be relatively movable with respect to the base 602a. As shown in FIG. 15, the moving part 602b has a plate-like piece extending forward from the lower end of the rod-like part 601. The tip of the plate-like piece has a first contact side 602L and the first contact side 602L. A substantially V-shaped notch 603 in plan view having a second contact side 602R arranged to intersect with the contact side 602L is formed.

  The measuring unit 602 configured in this manner is a so-called force sensor that can measure a shear force on the base 602a and a direction in which the shear force is applied by moving the moving unit 602b in the XYZ-axis directions with respect to the base 602a. (Also referred to as a strain gauge sensor). The valley of the substantially V-shaped notch 603 is a base point RP.

  Next, as shown in FIG. 14, using the inspection tool 600, the XY axis direction at a plurality of locations (two locations of the inspection points P1 and P2 in the present embodiment) of the body 200 a of the obstacle nail 200 in the Z-axis direction. The position (coordinates) of is measured. Then, an arithmetic unit (not shown) provided on the base 602a detects the degree of bending of the obstacle nail 200 based on the position data (coordinate data).

  More specifically, as shown in FIG. 15A, the base point RP of the inspection tool 600 is arranged at an inspection start position corresponding to each of the inspection points P1 and P2. Subsequently, as shown in FIG. 15B, the inspection tool 600 is moved in the XY axis direction (horizontal direction) so that the base point RP is located at the designated position. That is, if the designated nails 204 to 208 are arranged within the permissible range of the designated position by the second maintenance, the inspection of the base point RP is started without the first contact side 602L or the second contact side 602R coming into contact with the body 200a. It can be moved from a position to a specified position.

  However, when the obstacle nail 200 is not located within the allowable range of the designated position, the obstacle nail 200 is placed on one of the first contact side 602L and the second contact side 602R (for example, the second contact side 602R). Upon contact, pressure acts in the direction of the dotted arrow in FIG. 15B, and the moving portion 602b moves with respect to the base 602a. Thus, the shear force on the base 602a and the direction in which the shear force is applied are measured. The obstacle nail maintenance device 300 guides the inspection tool 600 in a direction in which the shearing force and the direction of the shearing force decrease (a direction in which the value becomes a minimum value). The above operation is repeated, and as shown in FIG. 15C, the base point RP of the inspection tool 600 is arranged at a position where it comes into contact with the obstacle nail 200. The obstacle nail maintenance device 300 completes the second maintenance including the above-described second inspection result information including the movement amount and the movement direction of the base point RP of the inspection tool 600 until the base point RP abuts on the obstacle nail 200. The data is transmitted to the management computer 500.

  The management computer 500 (CPU 502) that has received the second inspection result information (second maintenance completion data), based on the second inspection result information, moves the positions of the inspection points P1 and P2 with respect to the designated position in the XY axis direction. Identify the amount of deviation. That is, when the management computer 500 (CPU 502) contacts the first contact side 602L or the second contact side 602R while moving the base point RP of the first contact side 602L and the second contact side 602R toward the designated position. , The degree of bending of the trunk 200a is specified based on the amount of deviation from the designated position at each of the inspection points P1 and P2.

  As described above, the management computer 500 (CPU 502) not only determines the amount of displacement of the head 200b of the obstacle nail 200 with respect to the designated position in the XY axis direction, but also is a position different from the head 200b in the Z axis direction. The degree of deviation of the torso 200a of the obstacle nail 200 is specified by determining the amount of deviation of the torso 200a from the designated position at each of the inspection points P1 and P2 in the XY axis direction.

  The length of the head 200b of the obstacle nail 200 from the game board surface 2a is determined by specifying the degree of bending of the obstacle nail 200 from the amount of displacement of the body 200a from the designated position at the inspection points P1 and P2 in the XY axis directions. The dimensions can be specified. That is, even if the head 200b does not deviate from the set position in the XY axis directions, it is possible to grasp the problem that the trunk 200a is bent, so that the implanted state of the obstacle nail 200 can be inspected with high accuracy.

  For the nail 200 in which an abnormality is detected in the second inspection performed after the completion of the second maintenance in step S7, the management computer 500 (CPU 502) corrects the maintenance data corresponding to the second maintenance data (the second maintenance data). ) Is prepared, and the holding section 403 of the maintenance arm 301 is operated based on the corrected maintenance data. The second maintenance and the second inspection are repeatedly performed until the head 200b of the obstacle 200 after the second maintenance is located within the allowable range of the designated position or the number of times of the second maintenance reaches a predetermined number. Every time the second maintenance and the second inspection are performed, the second maintenance completion data is transmitted to the management computer 500.

  In the present embodiment, in the second inspection, the management computer 500 (CPU 502) moves the first contact side 602L while moving the base point RP of the first contact side 602L and the second contact side 602R toward the designated position. Alternatively, the form in which the degree of bending of the torso 200a is specified based on the amount of deviation from the designated position at each of the inspection points P1 and P2 by the load applied when the second contact side 602R is contacted is described. It is not limited to this, and the deviation from the designated position at each of the inspection points P1 and P2 based on the movement amount and the movement direction (movement trajectory) in which the base point RP has moved from the inspection start position to the position where it comes into contact with the obstacle nail 200 The amount may be measured to determine the degree of bending of the trunk 200a.

  Further, in the present embodiment, the form in which the second inspection is performed using the inspection tool 600 is illustrated, but the present invention is not limited to this, and the second inspection is performed by the camera in the obstacle nail maintenance device 300. You may do so.

  Next, the inspection of the obstacle nail 200 performed by the first nail inspection device 17A and the second nail inspection device 17B in steps S4 and S9 will be described with reference to FIG. 15A is a plan view showing the internal structure of the first nail inspection device and the second nail inspection device in FIG. 4, and FIG. 15B is a cross-sectional view taken along the line BB of FIG. Since the first nail inspection device 17A and the second nail inspection device 17B in this embodiment have the same configuration, only the configuration of the first nail inspection device 17A will be described, and the description of the configuration of the second nail inspection device 17B will be omitted. I do.

  As shown in FIG. 13, inside the first nail inspection device 17 </ b> A, a rectangular frame 43 in a plan view, which is disposed at a predetermined height by a plurality of standing legs 42, and a lower side of the center of the frame 43. That is, a plurality of cameras 44 (six in the present embodiment) fixed along the frame 43 in a state facing diagonally downward are provided, and the lower part of the frame 43 is moved by the above-described transport device 13. The game board 2 passes through. When the game board 2 is conveyed below the frame 43, the first nail inspection device 17A stops the conveyance device 13, and the plurality of cameras 44 photograph the entire game board 2. Then, the image data from the plurality of cameras 44 is transmitted to the management computer 500 together with the device number, the read data of the two-dimensional code 15a, and the like.

  The management computer 500 (CPU 502) integrates the received image data to specify the position (coordinates) of the head 200b of each obstacle nail 200 and the head of each obstacle nail 200 stored in the storage device 505. A check is made with the set position (designated position) of 200b to check whether there is any deviation from the set position.

  As described above, in the first nail inspection device 17A, the entirety of the game board 2 is photographed from the periphery of the game board 2 by the plurality of cameras 44 facing obliquely downward, and the image data is integrated and processed by the management computer 500, and each obstacle nail is In order to identify the position of the obstacle 200, not only the position of the obstacle nail 200 in the front-rear and left-right directions (the position in the X-axis and Y-axis directions) but also the position of the obstacle nail 200 in the height direction (the position in the Z-axis direction) It is possible to grasp and to inspect the implanted state of each obstacle nail 200 with high accuracy.

  In the present embodiment, as an example of grasping the position of each obstacle nail 200, the mode in which each of the obstacle nails 200 is photographed by the plurality of cameras 44 has been described. However, the present invention is not limited to this. As long as the position of each obstacle nail 200 can be grasped, for example, a sound wave sensor or an optical sensor may be used.

  As described above, in the first inspection, the CPU 502 determines whether the head 200b of each obstacle nail 200 is located within the allowable range of the set position based on the image captured by the camera 44 of the second nail inspection device 17B. On the other hand, in the second inspection, the measuring unit 602 (force sensor) provided on the inspection tool 600 arranges the head 200b of each obstacle nail 200 within the allowable range of the designated position. By determining whether or not the nail 200 is in a more accurate state than in the first maintenance, it is possible to perform highly accurate maintenance.

  Next, various data stored in the storage device 505 of the management computer 500 and a method of setting the data will be described with reference to FIGS.

  As shown in FIG. 18, the storage device 505 stores a plurality of model registration information in advance. This model registration information includes an item code, a material (a veneer plate or a synthetic resin plate), a nail position accuracy, a nail height accuracy, a windmill nail position accuracy, a windmill nail height accuracy, and a maintenance nail position accuracy, which are types of the game board 2. (Designated nail position accuracy), maintenance nail height accuracy (designated nail height accuracy), camera setting file, etc. are registered. Here, the nail position accuracy, the nail height accuracy, the windmill nail position accuracy, the windmill nail height accuracy, the maintenance nail position accuracy, and the maintenance nail height accuracy are allowable error ranges (allowable ranges). The type of the game board 2 is various, for example, the game board surface 2a is flat or has undulations (3D specification), and the camera setting file includes the camera 44 described above according to the model of the game board 2. This is data for setting the shooting angle.

  A serial number (unique ID) assigned to the two-dimensional code 15a attached to each game board 2, maintenance data, gauge data to be described later, and the like are stored in association with each item code. Accordingly, when the two-dimensional code 15a is read by the above-described reading camera, the management computer 500 extracts the item code corresponding to the read serial number, and stores the operation pattern data of various devices stored in association with the item code. The gauge data and the like are extracted, and various devices perform the above-described steps S3 to S9 based on the information.

  An interface for referring to the model registration information list is provided with a new addition button for newly registering the model registration information in the storage device 505. When this new addition button is selected, an interface for newly registering model registration information in the storage device 505 as shown in FIG. 19 is displayed on the display device 507. When newly registering model registration information in the storage device 505, the user first inputs an item code using a keyboard (not shown) or presses an automatic input button to select a corresponding item code from a list of item codes (not shown). And enter. Next, gauge data, which is a unique nail arrangement assigned according to the model of the game board 2, is input. This gauge data is inputted by selecting a corresponding gauge data from a gauge data list (not shown) by pressing a reference button. After that, the above-mentioned camera setting file and various nail precisions are input. In addition, the interface for new registration includes buttons for setting maintenance data using various maintenance tools 400 (also referred to as an accurate driver) and maintenance directions and angles of arbitrary nails.

  When an accurate driver maintenance data setting button is selected, an interface for setting accurate driver maintenance data appears as shown in FIG. This interface includes accurate information such as a maintenance location (type of designated nail), a nail number, a center position X, Y (coordinate data of the head 200b), an approach direction of the maintenance tool 400, maintenance data (operation pattern data), and the like. A driver list and a gauge data image (see the lower part of FIG. 20) are displayed. The designated nails can be set by inputting the designated nails 204 to 208 described above into the maintenance location (type of designated nail) displayed on this interface.

  In the column of maintenance data in the accurate driver list, one operation pattern data can be selected from a plurality of operation pattern data by a pull-down method, and a nail number, a center position X, Y (head 200b) (Coordinate data) and the approach direction of the maintenance tool 400 can be set.

  In addition, buttons at the bottom of the accurate driver list, such as a navel setting, a chucker setting, a passage gate setting, and a triangle setting, are arranged. By selecting an arbitrary button, the maintenance location associated with the button can be accurately determined. Selected in the driver list. When an arbitrary maintenance location is selected from the accurate driver list (in this embodiment, a burrow nail is selected), the area around the obstacle 200 selected in the gauge data image is colored, and the maintenance location selected by the operator is selected. It is easier to grasp. In the present embodiment, when an arbitrary maintenance location is selected from the accurate driver list, the area around the obstacle 200 selected in the gauge data image is colored. However, the present invention is not limited to this. If it is easy to grasp whether or not is selected, the area around the obstacle nail 200 selected in the gauge data image or the obstacle nail 200 itself may be turned on or blinking.

  When an operation such as double-clicking is performed in a state where an arbitrary maintenance point is selected from the accurate driver list, as shown in FIG. 21, as shown in FIG. The interface appears. In this interface, a nail swing angle, a nail swing movement amount, a Z-axis movement amount, a stop time, and a nail swing speed can be set for each maintenance data (operation pattern data). As described above, since various maintenance data (operation pattern data) can be set for each maintenance location (type of designated nail), the setting for bringing the specific obstacle 200 into a desired implantation state can be performed. It is simple.

  When the button for setting the maintenance direction and angle of the optional nail is selected in the above-described interface for new registration, an interface for setting the maintenance direction and angle of the optional nail appears as shown in FIG. . This interface includes a list of registrations such as nail numbers, center positions X and Y (coordinate data of the head 200b), height, direction, angle, type of driver (type of maintenance tool), etc., and gauge data images. (Refer to the lower part of FIG. 22). In the gauge data image in this interface, the specific nail 200 is colored, and the nail 200 of the nail number selected in the registration list is distinguished (in this embodiment, it is circled). In addition, the operator can easily grasp the obstacle nail 200 being selected. According to this, regardless of the type of the specific obstacle nail 200, the maintenance can be performed for each one of the obstacle nails 200, so that the specific obstacle nail 200 can be more finely maintained in a desired implantation state. I can do it.

  Next, the correction data of this embodiment stored in the storage device 505 will be described with reference to FIG. The correction data is for improving the maintenance accuracy of the obstacle nail 200. In fact, even if the same maintenance is performed in the obstacle nail maintenance device 300, if the maintenance position is different, a different maintenance result is obtained. In addition, for example, the maintenance result may be biased such that the distance between the obstacle nails 200 is small at a position near the turntable 312 and wide at the position far from the turntable 312. Further, such differences and deviations in the maintenance results depending on the maintenance positions have different tendencies and the like depending on the obstacle nail maintenance device 300, and there are so-called individual differences. Therefore, by eliminating the unevenness of the maintenance result due to the maintenance position or individual difference by using the correction data or the like, the maintenance accuracy of the obstacle nail 200 can be improved.

  Therefore, when the distance between the obstacle nails 200, in particular, the obstacle nails 200 of the designated nails 204 to 208 is set to a desired size, the correction data corrects the desired size so that the desired data can be obtained in the actual second maintenance. This is data to be maintained to have the dimensions described above, and is set based on the measured value of the standard maintenance at each position of the table 302 on which the game board 2 is placed.

  Specifically, as shown in FIG. 23, the area on the table 302 on which the game board 2 which is the maintenance-possible position of the present invention is placed is 10 steps in the front-rear direction and 5 rows A to E in the left-right direction. 50 divided (10 × 5) areas are set, and in each of the divided areas, the conditions of the material, tool, plate temperature, humidity, etc. are changed to set the interval between the obstacle nails 200 to 12. The standard maintenance for performing the maintenance to 00 mm is executed in the obstacle nail maintenance device 300, the distance between the obstacle nails 200 in each area is actually measured, and a correction value is calculated from the actually measured data. It should be noted that the correction value may be calculated from the average value by performing standard maintenance a plurality of times (for example, 10) under the same maintenance conditions (material, tool, plate temperature, humidity, etc.).

  As shown in FIG. 23, for example, as shown in FIG. 23, the interval between the obstacle nails 200 provided as standard in each of these areas may be equal to 12.00 mm, may be smaller than 12.00 mm, or 12. There is an area larger than 00 mm, and the correction data is calculated from the actual interval of the obstacle 200 and 12.00 mm which is the set value of the standard maintenance.

  That is, as an example of these correction data, for example, a value obtained by dividing the set value of 12.00 mm, which is the standard maintenance set value, by the actual measured value can be used. Specifically, if the measured value is 12.05 mm, 0.9959, which is a value obtained by dividing 12.05 mm by 12.05 mm, becomes the correction value data, and the interval to be actually maintained is 11.50 mm. In the case of millimeters, a value obtained by multiplying the correction data by 11.50 millimeters may be set as the interval specified in the maintenance.

  As described above, these correction data are created for each combination of various conditions such as the material of the game board 2, the board temperature, and the humidity, and are stored in the storage device 505.

  Therefore, when performing the second maintenance, the management computer 500 determines, out of the correction data, the correction data that matches the conditions such as the plate temperature and the humidity transmitted from the obstacle nail maintenance device 300, and The second maintenance data is created by correcting the correction data in the area where the position where the obstacle nail 200 is placed is applicable, and correcting the interval indicated by the specified correction data.

  In this embodiment, the correction data as described above is used. However, the present invention is not limited to this, and calculates the ratio (%) of the difference from the actual size. Actually, correction data that makes it easy to calculate the second maintenance data to be created, such as using the ratio (%) as a correction value, may be used.

  In the present embodiment, in the management computer 500, the maintenance method of the second maintenance is performed by either the maintenance method using the above-described correction data or the maintenance method not using the correction data. This can be set on the nail maintenance method setting screen displayed on the display device 507 by executing a predetermined setting operation.

  As shown in FIG. 24, on the nail maintenance method setting screen of this embodiment, check boxes are provided corresponding to the nail maintenance methods “one device complete method” and “multiple device sharing method”. The check box can be exclusively selected.

  The “one device completion system” is a maintenance system in which all the maintenance of one game board 2 is performed in each obstacle nail maintenance device 300 using the correction data described above. In other words, in each of the obstacle nail maintenance devices 300, as illustrated in FIG. 23, a region where good maintenance can be performed is different, and each of the obstacle nail maintenance devices 300 is peculiar. Therefore, for the area other than the area where the good maintenance can be performed, the correction data is used to correct the second maintenance data to be instructed so as to perform the good maintenance. This is a maintenance method in which the second maintenance is completed for the obstacle nail 200 in the area.

  On the other hand, the “plural device sharing method” means that a plurality of obstacle nail maintenance devices 300 share and maintain a second maintenance range, so that each obstacle nail maintenance device 300 has a maintenance habit (error). However, since the obstacles 200 in the same range of each game board 2 are maintained with the same habit (error), this is a maintenance method capable of suppressing variation in the quality of each game board 2.

  Therefore, on the nail maintenance method setting screen, as shown in FIG. 24, in the item of “multiple device sharing method”, the device number of the obstacle nail maintenance device 300 arranged on the production line 12 and the device number The range in which the obstacle nail maintenance device 300 performs the second maintenance can be set by selecting from six ranges R1 to R6. The ranges R1 to R6 are ranges obtained by dividing the range of the game board 2 into six, and when the range is selected, the measurement data of the standard maintenance of the corresponding obstacle nail maintenance device 300 (see FIG. 23). In the above, it is preferable to select an area where the measured interval is within a predetermined reference value from 12.00 mm, for example, ± 0.02 mm. However, it is not necessary to satisfy that all the regions corresponding to these ranges are within the predetermined reference value, and when there is no range in which all the regions are within the predetermined reference value, it is not necessary to satisfy the predetermined reference value. You may make it select the range which has many area | regions satisfying a certain thing. Note that these selections may not be input by the operator through operation, but may be automatically selected by the management computer 500.

  In addition, the reference value is not limited to the above, and may be appropriately determined according to the properties of the product, the type of the obstacle nail 200, and the like.

  As described above, when the “plural device sharing method” is set as the maintenance method on the nail maintenance method setting screen, the management computer 500 issues a message to each obstacle nail maintenance apparatus 300 on the nail maintenance method setting screen. A second maintenance is performed on the obstacle nail 200 in any one of the ranges R1 to R6 set in each obstacle nail maintenance device 300, that is, a range having an area satisfying a predetermined reference value. By transmitting the second maintenance data instructing that the second maintenance is not performed for the obstacle nail 200, each of the obstacle nail maintenance devices 300 performs the second maintenance in a different range. It should be noted that the second maintenance data in the “multiple device sharing system” is not corrected by the correction data unlike the second maintenance data in the “one device completion system”, and thus the management computer 500 creates the second maintenance data. The processing load of the processing to be performed can be reduced, and the second maintenance data can be transmitted to the obstacle nail maintenance device 300 quickly.

  As described above, in the “multi-device sharing system”, all the game boards 2 include the same error even if there is a habit (error) in the maintenance, and there is a variation between the game boards 2. Since this does not occur, as long as the area does not include the area where the maintenance is poor, a range that does not include many areas within the predetermined reference value may be specified.

  In the example shown in FIG. 24, the No. 01 obstacle nail maintenance device 300 installed on the manufacturing line 12 performs the second maintenance on the range R1, the No. 02 obstacle nail maintenance device 300 performs the second maintenance on the range R3, and the No. 03 obstacle nail maintenance device. Setting example in which the obstacle nail maintenance device 300 of No. 2 performs the second maintenance of the range R4, the obstacle nail maintenance device 300 of the No. 05 performs the second maintenance of the range R6, and the obstacle nail maintenance device 300 of the No. 06 performs the second maintenance of the range R5. The example in which six obstacle nail maintenance devices 300 from No. 01 to No. 06 share and perform the second maintenance is illustrated.

  Incidentally, since the habit (error) of maintenance of the obstacle nail maintenance device 300 often changes according to the number of times of performing maintenance, etc., these habits (error) of maintenance are measured again and shared. An item for setting a rotation study maintenance counter is provided to specify the timing of examining the change (rotation) of the range to be performed, and the number of maintenance until the change (rotation) of the range to be shared next time is considered for this item. By inputting, the value of the rotation examination maintenance counter is decremented by 1 each time the second maintenance is executed in each obstacle nail maintenance device 300, and the rotation of one of the obstacle nail maintenance devices 300 sharing the second maintenance is performed. When the examination maintenance counter becomes “0”, the standard maintenance is executed again, and the sharing range is reset. That is, in this embodiment, the measurement (detection) by the standard maintenance is executed every time the rotation examination maintenance counter, which is the execution condition for executing the re-measurement (redetection), becomes “0”.

  In this embodiment, the execution condition for executing the re-measurement (re-detection) is exemplified as the execution number of the second maintenance. However, the present invention is not limited to this. The condition may be executed at a constant cycle every time a predetermined period elapses.

  Next, the nailing data table of the present embodiment stored in the storage device 505 will be described. In the nailing data table of the present embodiment, as shown in FIG. 25, in correspondence with the device number of each nailing machine 16, the serial number of the game board 2 nailed by the nailing machine 16 of that number is stored. Information (data) such as a number, a date at the time of nailing, temperature, humidity, and the like are stored and managed.

  Therefore, the management computer 500 can identify the nailing machine 16 on which the obstacle nail 200 of the game board 2 has been set from the serial number of the gaming board 2 by using the nailing data table. It is also possible to specify the manufacturing conditions such as the date at which the nail 200 was driven and the temperature and humidity at that time.

  These data include temperature and humidity data included in the nailing work completion data transmitted together with the device number and the read data of the two-dimensional code 15a when the nailing machine 16 completes the setting of the obstacle nail 200. However, the present invention is not limited to this, and the data at the time of the data transmission request transmitted when the nailing machine 16 starts the driving includes the temperature and humidity data. The temperature and humidity data included in the data at the time of the request may be stored.

  Although not shown in FIG. 25, the storage device 505 of the management computer 500 is associated with the device number of each obstacle nail maintenance device 300 in the same manner as the nailing data table, and A failure nail maintenance data table that stores and manages information (data) such as the serial number of the game board 2 in which the final second maintenance was performed at 300, the date of maintenance, temperature, humidity, and the like is also stored. From the serial number of the game board 2, the second-managed obstacle nail maintenance device 300 of the obstacle nail 200 of the game board 2 can be specified by the obstacle nail maintenance data table. The second maintenance date and the manufacturing conditions such as temperature and humidity at that time can be specified.

  These data are the temperature and humidity data included in the second maintenance completion data transmitted together with the device number and the read data of the two-dimensional code 15a when the second maintenance described above is completed in the obstacle nail maintenance device 300. Is stored. As described above, in the present embodiment, the serial number and the temperature and humidity data included in the two-dimensional code 15a are associated with the device number of the obstacle nail maintenance device 300 that has performed the second maintenance. Although stored in the data table, the present invention is not limited to this, and similarly to the obstacle nail maintenance data table for the second maintenance, the obstacle nail maintenance device performing the first maintenance From 300, when the first maintenance is completed, the data including the two-dimensional code 15a of the game board 2 that has been subjected to the first maintenance and the temperature and humidity data transmitted together with the device number of the obstacle nail maintenance device 300 are included. Based on the first maintenance completion data, the serial number and temperature / humidity data included in the completion data are correlated with the device number of the obstacle nail maintenance device 300 that has performed the first maintenance. Of by storing the nails maintenance data table, also information about the first development to identify like the second maintenance, may be printed output to nail between measurements document which will be described later.

  Further, in the present embodiment, when the second maintenance (first maintenance) is repeatedly performed, data on the final second maintenance (first maintenance) is stored in the obstacle nail maintenance data table. However, the present invention is not limited to this. When the second maintenance (first maintenance) is repeatedly performed, the data on each second maintenance (first maintenance) is also stored in the obstacle nail maintenance data table. May be stored.

  Further, the maintenance method in the obstacle nail maintenance device 300 may be stored in the obstacle nail maintenance data table. Further, when the “one device completion method” using the correction data is executed as the second maintenance method, the obstacle nail 200 targeted for the second maintenance is used for the maintenance of the obstacle nail 200. The correction data (correction value) may also be stored so that it can be checked later. If the “multiple device sharing method” is executed, the nail nail maintenance that has performed the second maintenance of each of the ranges R1 to R6 is performed. Individual difference information such as an error (individual difference) and correction data (correction value) in the range of the device 300 may be stored so that it can be confirmed later. Further, these maintenance methods and individual difference information may be described in a nail-to-nail measurement report shown in FIG. By doing so, in the obstacle nail maintenance data table, the game board 2 is associated with the serial number serving as identification information that can be individually identified, and the book about the second maintenance of the obstacle nail 200 of the game board 2 is provided. The correction data as the individual difference information of the invention is stored and managed.

  In addition, as shown in FIG. 26, the second image inspection table of the present embodiment associates the first inspection in the second nail inspection device 17B with the corresponding number with the device number of each second nail inspection device 17B. Information (data) such as the serial number of the game board 2 performed, the date at the time of inspection, and the temperature and humidity at the time of the inspection is stored and managed.

  Therefore, the management computer 500 can identify, from the serial number of the game board 2, the second nail inspection device 17 </ b> B that has performed the first inspection of the game board 2 by using the second image inspection table and the second nail inspection device 17 </ b> B. It is also possible to specify manufacturing conditions such as the date of inspection, temperature, humidity, and the like.

  Although FIG. 26 illustrates the second image inspection table, the storage device 505 of the management computer 500 also stores a first image inspection table similar to the second image inspection table. In the 1 image inspection table, the serial number of the gaming board 2 inspected by the first nail inspection device 17A of the corresponding number, the date at the time of inspection, and the like are associated with the device number of each first nail inspection device 17A. Information (data) such as temperature and humidity at the time of inspection is stored and managed, and the first nail inspection device 17A that primarily inspects the game board 2 is subjected to the first image inspection based on the serial number of the game board 2. In addition to being able to be specified by the table, the first nail inspection device 17A can also specify the date of primary inspection, manufacturing conditions such as temperature and humidity.

  In this embodiment, based on various data stored in the storage device 505 of the management computer 500, in the present embodiment, a nail gap measurement report is printed out by the printer 508, and the pachinko machine which is a purchaser of the game board 2 is printed. The game machine 1 is provided to the purchaser.

  As shown in FIG. 27, the front-to-back view of the game board 2 is printed on the left half of the paper, and the devices and conditions for manufacturing and maintenance, and the designated nails are printed on the left half of the paper. Information between the nails and information on a predetermined highly-important obstacle nail 200 are printed.

  More specifically, as shown in FIG. 27, symbols A to F are printed on the front view of the game board 2 so that the user can understand which part of the game board 2 the letters A to F indicate. At the same time, a prescribed value of the size of the winning opening in the portions A to F is printed below the sheet.

  Further, in the front view of the game board 2, all the obstacle nails 200 to be cast on the game board are printed in a circle, and data such as angle and direction of the obstacle nails 200 are required. Obstacle nails 200 with high importance are displayed as black circles, and numbers [1] to [22] are printed in the vicinity.

  Further, on the right side of the display of the prescribed value of the size of the winning opening, an explanatory diagram for explaining which interval of the position in the obstacle nail 200 is which name is printed.

  At the top of the nail-to-nail measurement report, the title of the “nail-to-nail measurement report”, the date printed, and the model name are printed. In the upper right part of the page, item data such as a serial number, a development number, and a nailing data name are printed.

  Further, as shown in FIG. 27, on the right side of the paper, information relating to the nailing of “nailing date”, “nailing machine number”, and “plate thickness” is printed. Below it, after the nail position of “Image inspection date”, “Nail position measuring machine”, “Nail height accuracy MAX”, “Nail height accuracy MIN”, “Temperature”, “Humidity”, “Sheet temperature” The information about the first image inspection is printed.

  Below this, information on nail maintenance, such as “Nail maintenance date”, “Nail maintenance machine”, “Temperature”, “Humidity”, and “Sheet temperature” is printed, and further below that, “Image inspection date” , "Nail position checker", "Temperature", "Humidity", and "Plate temperature" are printed with information on the final image inspection.

  Further, further below, information on the intervals between winning ports A to F shown in the front view on the left side of the paper is printed.

  Further, on the right end of the paper, information regarding the “angle” and “direction” of the obstacle nails 200 [1] to [22] shown in the front view on the left side of the paper is printed in association with the number of each obstacle nail 200. Have been.

  Note that the “angle” is such that the angle perpendicular to the game board surface 2a is “0 degree”, and the angle becomes larger as the tip of the obstacle nail 200 is inclined toward the upper side of the game board surface 2a. And the "direction" is shown in the drawing to indicate that the time indicated by the hands of the clock is indicated by the corresponding direction in the top view of the obstacle nail 200. I have.

  As described above, as shown in FIG. 27, a lot of information on the maintenance of the obstacle nail 200 is printed on the inter-nail measurement report of the present embodiment, but the present invention is not limited to this. Instead, the type, content and display method of the information on the maintenance to be printed can be changed as appropriate. In other words, the information on the maintenance includes information on the maintenance of the nail 200, which device nailed or performed the maintenance, conditions such as temperature and humidity when the nailing or the maintenance was performed, and failures after the maintenance. Only one of the information such as the angle and the direction of the nail 200 and the interval between the winning holes may be used.

  Further, in the present embodiment, as shown in FIG. 27, a form in which a related person such as a purchaser of the pachinko gaming machine 1 outputs a nail-to-nail measurement report that can be directly read, is used. The present invention is not limited to this. For example, the page data of the inter-nail measurement report is stored in the management computer 500 in association with the page identification information such as the serial number of the game board 2 to which the inter-nail measurement report corresponds. The related person outputs only the encrypted information that cannot be directly read, such as a bar code obtained by encoding the page specifying information or a two-dimensional code obtained by symbolizing the page identification information, and outputs the encrypted information. The page identification information is extracted by reading with a predetermined terminal, and the page data of the nail gap measurement book stored in the management computer 500 in association with the extracted page identification information is obtained. It may be Shimesuru so. In addition, the page data of the nail gap measurement book is stored in the specific management server computer instead of the management computer 500 in association with the page identification information such as the serial number of the game board 2, and the specific management server computer , And by inputting the page identification information on the dedicated page, the page data of the nail-measurement report is distributed and displayed on a terminal (for example, a smartphone or a tablet) or the like that can be used by a related person. It may be. As described above, by outputting only the encrypted information that cannot be directly read by the related person, the output information about the maintenance is less likely to be tampered with, thereby improving the security of the information about the maintenance. it can.

  When outputting a bar code or symbolized two-dimensional code obtained by encoding the page specifying information, the bar code or the two-dimensional code is not output, but the two-dimensional code 15a shown in FIG. As described above, along with the barcode and the two-dimensional code, part of the information on the maintenance described in the nail-to-nail measurement report specified from the barcode and the two-dimensional code, for example, By printing out the data of the measured values such as the nail maintenance date and winning opening, the information on the maintenance printed out together with these barcodes and two-dimensional codes can be directly obtained without using a predetermined terminal etc. You may make it readable. By doing so, even when a predetermined terminal cannot be used, information on maintenance can be confirmed.

  As described above, according to the present embodiment, as shown in FIG. 11, in the obstacle nail maintenance device 300, depending on the type of the second maintenance (nail type, maintenance tool type, maintenance deformation amount (maintenance operation)). When different clamp control patterns are determined, different holding control is performed, so that the game board can be suitably held, so that different types of maintenance can be appropriately performed. The types of maintenance are not limited to those illustrated in the present embodiment, and may be different from the types illustrated in the present embodiment. Specifically, instead of the maintenance deformation amount (movement amount of the maintenance tool), the maintenance may be performed at a different moving speed of the maintenance tool, or a difference in a movement path of the maintenance tool or a position where the maintenance tool abuts on the nail 200. .

  Further, according to the present embodiment, in the table 302 of the obstacle nail maintenance device 300, the game board 2 has a guide hole formed in the game board 2 and a guide pin having a smaller diameter than the inner diameter of the guide hole. In this state, since it is urged in the horizontal direction crossing the guide pin, the positional accuracy of the held game board can be improved.

  Further, according to this embodiment, in the first maintenance and the second maintenance, after the first maintenance (primary maintenance) is performed, the state of the repaired nail 200 is detected, and the detected state is determined to be a predetermined appropriate level. It is determined whether or not the vehicle is in a state, and if the vehicle is not in a predetermined proper state, based on the detected state, re-maintenance different from the initial maintenance, specifically, as shown in FIG. In the first re-maintenance, the modified example (maintenance amount), which is an example of the maintenance operation, is changed. In the second re-maintenance, the maintenance tool 400 used is changed. Since the maintenance is performed with the device 300 changed, occurrence of a failure nail with poor maintenance can be prevented.

  In the above-described embodiment, an example is described in which the management computer 500 determines whether or not the detected state is a predetermined appropriate state. However, the present invention is not limited to this. In the case where these determinations are made on the side of each nail maintenance device 300 or the state of the obstacle 200 after maintenance is detected by the first nail inspection device 17A and the second nail inspection device 17B, etc. May be performed by each of the first nail inspection device 17A and the second nail inspection device 17B, that is, by the device that detects the state of the obstacle nail 200.

  Further, according to the present embodiment, even if the re-maintenance is performed a predetermined number of times (three times in the present embodiment), if the state of the obstacle nail 200 is not the predetermined appropriate state, the first maintenance or the second maintenance is performed. Since the maintenance is completed and the target is set as a discharge target from the production line 12, it is possible to prevent the occurrence of inconveniences such as re-maintenance (secondary maintenance) being performed more than necessary and reducing the production efficiency. be able to.

  Further, according to the present embodiment, as shown in FIG. 23, standard maintenance is performed such that the interval between the obstacle nails 200 in different regions (positions) on the game board surface 2a is 12.00 mm which is a standard state ( Standard maintenance process), the interval between the obstacle nails 200 after the standard maintenance is detected in order to detect an individual difference which is an error between the distance between the obstacle nails 200 subjected to the standard maintenance and the standard state of 12.00 mm. (Nail state detection step), correction data for each area is created from the individual difference obtained by the detection, and if the “one-device complete method” is set as the maintenance method in the management computer 500, the maintenance is performed. Since the second maintenance is performed based on the second maintenance data corrected by the correction data corresponding to the area (position) where the target obstacle nail 200 is provided, the failure of the maintenance nail 200 due to the difference in position is generated. It is possible to prevent.

  In addition, according to the present embodiment, as described above, the standard maintenance (standard maintenance process), the individual difference which is an error between the distance between each of the nails 200 subjected to the standard maintenance and the standard state of 12.00 mm. Is detected (nail state detection step), and when the “many device sharing method” is set as the maintenance method in the management computer 500, the individual difference falls within a predetermined reference value for performing the maintenance with a good individual difference. The second maintenance of the obstacle nail 200 is performed for the range (any one of the ranges R1 to R6) to which the area (position) belongs to, and the area (position) not within the reference value, that is, the obstacle nail in the nail maintenance method setting screen is displayed. By not performing maintenance of the obstacle nail 200 in a range not set for the maintenance device 300 (good partial maintenance process), it is possible to prevent the occurrence of the failure of the maintenance nail 200 due to a difference in position.

  In the above-described embodiment, the management computer 500 exemplifies a mode in which the maintenance system can be selected and set from the “one-device-complete system” and the “multiple-device sharing system”, but the present invention is not limited to this. Instead, only one of these maintenance methods may be performed.

  Further, according to the present embodiment, in the obstacle nail maintenance device 300, since the position deviation can be confirmed by the detection pin G and the position deviation confirmation tool 400 ', it is possible to prevent a decrease in maintenance accuracy due to the position deviation. In the above-described embodiment, the detection pin G and the position deviation confirmation tool 400 'are used as the position deviation confirmation means. However, the present invention is not limited to this. The displacement may be confirmed by a method other than the method using the displacement confirmation tool 400 '.

  Further, according to the present embodiment, every time the execution condition (re-detection execution condition) for executing the re-measurement (re-detection) of the individual difference by the standard maintenance is satisfied, the re-measurement (re-detection) by the standard maintenance is executed. Therefore, even if an error (individual difference) changes due to maintenance, maintenance corresponding to the change can be performed.

  Further, according to the present embodiment, individual difference information such as correction data for the second maintenance of the obstacle nail 200 of the game board 2 is stored in association with the serial number of the game board 2 in the obstacle nail maintenance data table. Since it is managed, individual difference information can be managed for each game board 2.

  In the present embodiment, a plurality of obstacle nails 200 provided on the game board surface 2a of the pachinko gaming machine 1 are maintained, and a deviation from a predetermined set position among the plurality of obstacle nails 200 is performed. First maintenance performed in step S5 for the obstacle nail 200 that is out of the allowable range, and in step S7 for a previously designated obstacle nail (for example, designated nails 204 to 208) among the plurality of obstacle nails 200. The second maintenance to be performed can be executed. In the second maintenance, maintenance different in content from the first maintenance is performed. By doing so, in the first maintenance, the deviation from the set position can be uniformly maintained for the plurality of obstacle nails 200, and in the second maintenance, the deviation maintenance can be performed for the previously specified obstacle nail. Can be performed with different contents, so that detailed maintenance can be performed according to the nail arrangement (gauge) of the obstacle nails 200 and the like.

  The obstacle nail maintenance system of the present invention has a nail driving machine 16 for driving a plurality of obstacle nails 200 into the game board surface 2a of the pachinko gaming machine 1 and a deviation from a predetermined setting position for each of the plurality of obstacle nails 200.

The management computer 500 includes a specific obstacle among the obstacle nails 200 provided on the game board surface 2a. Obstacle nail designating means for designating nails (for example, a maintenance location (type of designated nail) displayed on an interface for setting accurate driver maintenance data) and an obstacle nail maintenance device On the other hand, the first maintenance instruction means (00) instructs the first nail inspection device 17A or the second nail inspection device 17B to execute the first maintenance for the obstacle nail whose deviation from the set position is determined to be outside the allowable range. For example, the CPU 502 that has received the inspection result data determines that among the obstacle nails 200 driven in the step S3, the inspection in the step S4 indicates that the deviation in the XY-axis direction with respect to the set position of the head 200b is outside the allowable range. The first maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the set position is created for the obstacle nail 200, and the first maintenance data is stored in the obstacle of the transport destination of the game board 2. A part which transmits to the nail maintenance device 300 and instructs execution of the first maintenance) and instructs the obstacle nail maintenance device 300 to execute the second maintenance for the obstacle nail designated by the obstacle nail designating means. 2 The maintenance instructing means (for example, the CPU 502 targets the obstacle nails 200 (for example, the designated nails 204 to 208, etc.) designated in advance according to the type of the game board 2 among the plurality of obstacle nails) A part that transmits second maintenance data for positioning the head 200b within the allowable range of the designated position to the obstacle nail maintenance device 300 and instructs execution of the second maintenance). Perform maintenance that differs in content from the first maintenance. In this manner, in the first maintenance, the deviation from the set position can be uniformly maintained for the plurality of nails 200, and in the second maintenance, the deviation of the predetermined nail 200 can be maintained in the second maintenance. Since different maintenance can be performed, detailed maintenance according to the nail arrangement (gauge) or the like of the obstacle nail 200 becomes possible.

  The management device according to the embodiment of the present invention is a management computer 500 that controls the obstacle nail maintenance device 300 that maintains the plurality of obstacle nails 200 provided on the game board surface 2a of the pachinko gaming machine 1. Obstacle nail designating means for designating a particular obstruction nail out of a plurality of obstruction nails 200 provided in 2a (for example, a maintenance location (type of designated nail) displayed on an interface for setting accurate driver maintenance data) Then, the first nail inspection device 17A or the second nail inspection device 17B instructs the obstacle nail maintenance device 300 to execute the first maintenance for the obstacle nail whose deviation from the set position is determined to be outside the allowable range. The first maintenance instructing means (for example, the CPU 502 that has received the inspection result data determines which one of the nails 200 that was driven in step S3 has the head 200b The first maintenance data for disposing the head 200b of the obstacle nail 200 within the tolerance of the set position is targeted for the failure nail 200 determined to be out of the tolerance in the XY axis directions with respect to the set position. The first maintenance data is transmitted to the obstacle nail maintenance device 300 at the destination of the game board 2 to instruct execution of the first maintenance) and the obstacle nail designating means The second maintenance instructing means (for example, the CPU 502 determines, among the plurality of obstacle nails, the obstacle nail 200 specified in advance in accordance with the type of the game board 2 (for example, For the designated nails 204 to 208, etc., the second maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the designated position is transmitted to the obstacle nail maintenance device 300 to execute the second maintenance. Instruct And output means (for example, a nail-to-nail measurement report shown in FIG. 27) capable of outputting information related to the obstacle nail including at least the information related to the maintenance transmitted from the obstacle nail maintenance device 300 for each gaming machine. And a printer 508) for performing printout. In the second maintenance, maintenance different from the first maintenance is performed. In this manner, in the first maintenance, the deviation from the set position can be uniformly maintained for the plurality of nails 200, and in the second maintenance, the deviation of the predetermined nail 200 can be maintained in the second maintenance. Since different maintenance can be performed, detailed maintenance according to the nail arrangement (gauge) or the like of the obstacle nail 200 becomes possible.

  In addition, when there are a plurality of obstacle nail maintenance devices 300, the output nail-to-nail measurement report includes, of the plurality of obstacle nail maintenance devices 300, the obstacle nail that has been maintained as described in the nail-to-nail measurement report. By including maintenance device identification information such as a device number that can identify the maintenance device 300, when a defect or the like occurs, a faulty nail maintenance device that has performed the defective maintenance can be easily specified.

  In addition, by performing the second maintenance after performing the first maintenance, the second maintenance can be performed in a state where the gap has been maintained in the first maintenance, so that the second maintenance can be accurately performed.

  In addition, first determining means (for example, the CPU 502 of the management computer 500 determines whether the deviation from the set position of the nail 200 having undergone the first maintenance is within an allowable range. Regarding the later obstacle nail 200, it is determined whether or not each obstacle nail 200 is inclined about 4 degrees upward with respect to the Z-axis direction orthogonal to the game board surface 2a from the gauge data corresponding to the game board 2. A part that is determined based on the direction and amount of misalignment of the head 200b of the obstruction nail 200 with respect to the set position in the XY axis directions) and a designated position predetermined for the obstruction nail 200 that has undergone the second maintenance. The second determining means (for example, the CPU 502 of the management computer 500 determines whether or not the head 200b of the designated nail 204 that has undergone the second maintenance) determines whether the deviation is within an allowable range. A part for determining whether or not it is arranged within the allowable range of the fixed position), and the method of determination by the first determining means and the method of determination by the second determining means are different from each other, so that a method according to the maintenance content is provided. Can be determined efficiently.

  Further, the second determining means determines whether or not the deviation from the designated position is within an allowable range based on the measurement result using the force sensor. I can figure it out.

  Further, the force sensor has a first contact side 602L and a second contact side 602R arranged to intersect with the first contact side 602L, and the first contact side 602L and the second contact side Due to the load applied when contacting the first contact side 602L or the second contact side 602R while moving the base point RP with the designated position 602R toward the designated position, the deviation from the predetermined designated position is within an allowable range. Since it is determined whether or not there is, the state of the obstacle nail 200 that has been maintained can be grasped in detail.

  In the first inspection, the management computer 500 (CPU 502) arranges the head 200b of each of the obstacle nails 200 within the allowable range of the set position based on the image captured by the camera 44 of the second nail inspection device 17B. It is determined whether or not a plurality of cameras 44 are fixed to the predetermined frame 43, so that the state of the obstacle nail can be grasped in detail.

  In addition, it has a measuring means (for example, a hygrometer or a thermometer) capable of measuring the state of the outside air, and performs the first maintenance and the second maintenance based on the measurement result of the measuring means, so that the first maintenance and the second maintenance can be performed. Maintenance accuracy can be improved.

  In the second inspection, the management computer 500 (CPU 502) arranges the head 200b of each obstacle nail 200 within the allowable range of the designated position by the measuring unit 602 (force sensor) provided on the inspection tool 600. Is determined, and the degree of bending of the obstacle nail 200 is determined based on the amount of deviation of the body 200a from the designated position at each of the inspection points P1 and P2 in the X and Y directions, thereby playing the head 200b of the obstacle nail 200. Since the length dimension from the board surface 2a can be specified, the state of the obstacle nail 200 can be grasped in detail.

  Also, a holding portion 403 that can be arranged so as to sandwich the body 200a of the obstacle nail 200, and operating means for operating the holding portion 403 (for example, the CPU 502 of the management computer 500, the maintenance arm 301 of the obstacle nail maintenance device 300, the maintenance) And a driving source of the arm 301 for use), and operating the holding portion 403 by the operating means to maintain the obstacle nail in which the body portion 200a is held by the holding portion 403. The holding portion 403 can be moved in the XY-axis direction, which is a direction along the game board surface 2a, and in the Z-axis direction, which is a direction orthogonal to the game board surface 2a, and the body portion 200a is moved by moving the holding portion 403. , A second step of inclining the holding section 403 in one direction in the XY axis direction at the first position, and placing the holding section 403 in the first position. A third step of tilting in the other direction of the XY-axis direction together by moving the Z-axis direction disposed on the second position away from the game board 2a than the first position from a possible execution. By doing so, not only the operation of tilting the holding portion 403 in one direction of the XY axes but also the operation of returning the holding portion 403 in the other direction can apply a well-balanced force to the body portion 200a. In addition, after the holding portion 403 arranged at the first position is tilted in one direction in the XY axis direction, it is not only returned to the other direction but also moved to the second position, so that only a part of the body portion 200a has a bending force. Since it is possible to avoid acting in a concentrated manner, it is possible to stably maintain the body 200a without bending it halfway.
