As described above, the main control CPU 40a or the sub control CPU 41a serves as an error detection unit that detects various errors occurring in the gaming machine.

  When the error control command is input from the main control CPU 40a or when an error is detected, the sub control CPU 41a of the sub control board 41 specifies the type and time of detection of the error, and the history is used as the error history. Store in the sub-control RAM 41c. Thereby, the sub-control RAM 41c serves as an error storage unit that stores the error history of the detected error.

Next, an error history display method will be described.
An operator who confirms the error history (for example, an administrator of the slot machine 10) first operates the locking device 32 of the front door 12 shown in FIG. 1 and unlocks the locking device 32 to open the front door 12. Open. When the front door 12 is opened, it becomes possible to operate the setting device 33 as setting operation means accommodated in the main body 11. Then, the operator inserts a setting key into the key hole 34 of the setting device 33 and turns it on. As a result, the slot machine 10 transitions to a state where the error history can be confirmed. At this time, the setting value of the slot machine 10 can be changed and can be confirmed. That is, the setting value can be changed by inserting a setting key into the key hole 34 of the setting device 33 and operating a setting button for changing a setting value (not shown) in the ON state. The setting button exists inside the slot machine 10 and is configured not to be operated unless the front door 12 is opened.

  When the setting device 33 is turned on, an operation signal indicating an ON operation is input from the setting device 33 to the main control CPU 40a of the main control board 40. The main control CPU 40 a that has input the operation signal of the setting device 33 outputs the operation signal to the sub control CPU 41 a of the sub control board 41. Thereby, the sub-control CPU 41a can recognize that the setting device 33 has been turned ON.

  When the setting operation button BT1 disposed on the front door 12 is operated by the operator after the setting device 33 is turned on, an operation signal is input from the setting operation button BT1 to the sub control CPU 41a. Then, the sub-control CPU 41a causes the effect display device 14 to display a menu screen indicating items that can be executed by the worker.

FIG. 4 shows an example of the menu screen 35.
The menu screen 35 shows, for example, items for instructing time setting, items for instructing reference to various history information, and the like. Further, an item 36 (error history) relating to display of the error history is shown on the menu screen 35. An item 37 (setting value history) relating to the setting value history is shown on the menu screen 35. Then, the operator can select an item from the menu screen 35 by operating the setting operation button BT1.

  Here, when the item 37 regarding the setting value history is selected, a screen for displaying the setting value history that has been set up to that point is displayed. That is, when the setting key is inserted into the keyhole 34 of the setting device 33 and the item 37 relating to the setting value history is selected in the ON state, the setting value history (including the current setting value) is confirmed. be able to.

Here, when the item 36 relating to error history display is selected, a screen for displaying the error history is displayed.
As shown in FIG. 5, the error history is configured to be displayed for each predetermined display page, and an upper limit is determined in advance for the number of errors that can be displayed on one display page. The portion exceeding the upper limit is configured to be displayed on the next display page, and the operator (administrator) of the amusement shop can arbitrarily set each operation by operating the setting operation button BT1. The display page can be displayed. That is, the error history is configured so that the upper limit number of errors that can be displayed on one display screen is displayed for each predetermined display page, and the detected error number is equal to the upper limit number. When it exceeds, it is displayed over a plurality of display pages.

  In each display page, errors detected in order from the top are arranged according to the detection order. That is, when the error history is displayed on the effect display device 14, the detected and stored errors are arranged in the order of detection and displayed on the display screen. In each error item, the type of error and the time of detection are displayed. Also, the error on the screen is newly detected. Further, when an error is newly detected, it is added to the top row of the latest display page. At this time, regardless of which display page is displayed, the effect display device 14 displays the latest display page and displays the latest error. That is, when the sub control CPU 41a detects a new error while displaying the error history, the sub control CPU 41a updates the error history and displays the new error on the currently displayed display screen. It is supposed to let you. More specifically, the sub-control CPU 41a detects the new error while displaying the error history, and updates the error history, regardless of which display page is displayed. The latest display page with various errors added is displayed.

  The operator (administrator) of the amusement shop can know the number of detected errors, the time of detection, and the type by looking at the error history, and based on this, find out whether there is a malfunction or fraud in the gaming machine. can do. Thereby, the sub-control CPU 41a serves as a display control means for displaying the error history on the effect display device 14 as a display means.

Next, a process when an error occurs while displaying an error history will be described.
As shown in FIG. 6A, when the error history is displayed on the effect display device 14 and any one of the display pages is displayed, if a door open error is detected, the sub-control CPU 41a Is added to the error history, and the stored contents of the sub-control RAM 41c are updated. At this time, when a door close error is detected, the sub control CPU 41a newly adds the error to the error history, and updates the stored contents of the sub control RAM 41c.

  Then, as shown in FIG. 6B, the sub-control CPU 41a displays the latest display page to which the door close error which is the latest error is added, regardless of which display page is displayed. It is displayed on the effect display device 14. Thereby, the operator (administrator) of the amusement shop can recognize the door close error added to the top row of the latest display page.

  The situation where a door close error is detected while the error history is displayed is equivalent to the situation where the key is inserted into the setting device 33 and the front door 12 is opened and closed. For this reason, the front door 12 is closed while leaving a key that can be used to change the setting value inside the main body 11 of the slot machine 10 by recognizing the door close error by the operator (administrator) of the game shop. Can be prevented.

As described above in detail, the present embodiment has the following effects.
(1) If the main control CPU 40a or the sub control CPU 41a detects a new error while displaying the error history, the sub control CPU 41a updates the error history and displays it now. The new error is displayed on the display screen. Accordingly, when an error occurs while the error history is displayed, the operator (administrator) generates a new error without switching the display screen using the setting operation button BT1. You can also know the type. For this reason, it is easy to check the error history, and work can be performed efficiently.

  (2) When the error history is updated while the error history is being displayed, the sub-control CPU 41a is updated with the new error added regardless of which display page is displayed. Display the display page. Thereby, when an error occurs while the error history is being displayed, the operator (administrator) can operate the setting operation button BT1 and perform a new operation without changing the display page. Knows what kind of error occurred and what kind of error it is. For this reason, it is easy to check the error history, and work can be performed efficiently.

(3) Since the error history is displayed on the effect display device 14 with a wide display area in which the game effect is executed, when an error occurs, it can be found immediately.
(4) When the front door 12 is opened or closed with the setting key inserted in the setting device 33 (when a door open error or a door close error is detected), it can be displayed. . For this reason, when the setting key used for changing the setting value is left in the main body 11, the operator (administrator) can immediately find out that the key remains. It is possible to prevent the work from being finished. That is, it is possible to prevent the setting key from being lost.

In addition, the said embodiment can be actualized in another embodiment (another example) as follows.
In the above embodiment, the error history may be continuously displayed on the effect display device 14 while the key is inserted into the setting device 33. Thereby, when the key is inserted in the setting device 33, the game effect is not executed or is hardly performed, and it can be easily found that the key is left in the main body 11.

  In the above embodiment, the setting operation button BT1 may be provided either inside or outside the main body 11 of the slot machine 10. Further, other buttons (for example, stop buttons 23L, 23C, 23R) may be substituted.

  In the above embodiment, the error history display mode and storage mode may be arbitrarily changed. For example, all errors may be displayed on one screen. Further, errors may be sequentially displayed by scrolling the display screen. Further, a predetermined number or more may be deleted. Further, an error that has been detected for a predetermined period or longer may be deleted.

  In the above embodiment, the effect display device 14 displays the error history, but other display means may display the error history. For example, the error history may be displayed on a hall computer connected to the slot machine 10.

-In the said embodiment, it is not necessary to confirm the log | history of a setting value.
In the above embodiment, a setting key may be inserted into the key hole 34 of the setting device 33 so that the set value can be confirmed without being turned on. For example, the current setting value may be confirmed according to the setting state of the setting button.

Next, a technical idea that can be grasped from the above embodiment and another example will be added below.
