  The MPU 41 of the display control board D is for controlling the display of the liquid crystal display device 10 based on the display command transmitted from the main control board C, and is transmitted from the gate array 70 at a predetermined time interval. The usage time of the liquid crystal display device 10 or the like is measured based on the signal. The ROM 42 is a memory for storing various control programs and fixed data executed by the MPU 41. The programs in the flowcharts shown in FIGS. 4 to 8 are stored in the ROM 42 as a part of the control program. . The EEPROM 43 is for storing the total usage time data actually used by the liquid crystal display device 10 and the like, and includes a liquid crystal panel memory 43a, a backlight memory 43b, a display control board memory 43c, and a liquid crystal control board.

In each of the memories 43a to 43d, time data is added at regular intervals by the MPU 41 (for example, time data “1” is added at one hour intervals), and after the addition, updated total usage time data is stored. The The EEPROM 43 is composed of a rewritable nonvolatile memory, and can maintain data storage without a backup power supply even after the pachinko machine 1 is powered off. The EEPROM 43 only needs to be a rewritable nonvolatile memory, and may be constituted by a flash ROM, for example.

The liquid crystal control board L is separably connected to the display control board D via the connector 52, and is separably connected to the liquid crystal panel 53 and the backlight 54 via connectors 55 and 56, respectively.

  Next, each process executed by the pachinko machine 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 4 is a flowchart showing a main process executed on the display control board D of the pachinko machine 1. By this main process, each process necessary for the display control board D, such as control of image display, is executed. In this main process, first, after the power is turned on, an initialization process is executed such that the contents of the work RAM 44 and the like are once cleared to “0” and then set to initial values (S1). However, in this initialization process, the contents of the total usage time data stored in the memories 43a to 43d of the EEPROM 43 are not cleared. After the initialization process of S1, “1” is added to the total use time data stored in each of the memories 43a to 43d of the EEPROM 43, and the total use time data is updated (S2). The total usage time data stored in each of the memories 43a to 43d of the EEPROM 43 is updated by adding the time data “1” to a predetermined time interval as described later. Therefore, every time the power of the pachinko machine is turned off, the usage time from the last update of the total usage time data to the time of power off is not measured, and a measurement error accumulates every time the power is turned off. . Due to this measurement error, the value of the total use time data stored in each of the memories 43a to 43d of the EEPROM 43 is measured less than the actual use time. Therefore, when the liquid crystal display device 10 is reused, there is a problem that the reliability is lowered. Therefore, by executing the process of S2 every time the power is turned on, the measurement error accumulated when the power is turned off can be adjusted, and an accurate total usage time can be measured. After execution of the process of S2, each process executed on the display control board D is repeated (S3).

  FIG. 5 is a flowchart showing an INT interrupt process executed at regular intervals on the display control board D of the pachinko machine 1. This INT interruption process is a process for measuring the usage time of the liquid crystal display device 10 and the like and storing it in the memories 43 a to 43 d of the EEPROM 43. Regarding this INT interrupt processing, the CPU 41 adds “1” to the total use time data stored in each of the memories 43a to 43d of the EEPROM 43, and updates the total use time data (S11). After executing the process of S11, this INT interrupt process is terminated. Since this INT interrupt processing is periodically repeated every time a certain time elapses while the power is turned on, the values of the memories 43a to 43d of the EEPROM 43 are "1" every certain time. The updated value is stored in the EEPROM 43 composed of a non-volatile memory even after the power is turned off. Thereby, the CPU 41 can quantitatively grasp the total use time of the liquid crystal display device 10 and the like by reading the values (total use time data) stored in the memories 43 a to 43 d of the EEPROM 43.

  When the memory for storing the total use time data is configured by the EEPROM as shown in the present embodiment, the fixed time interval at which the above INT interrupt processing is executed is set to about 1 hour, for example. Is desirable. At present, the number of write guarantees of a commonly used EEPROM is about 100,000 times. Therefore, even when the gaming machine is continuously used, the writing process can be executed every hour over a period of 10 years or more, which is sufficient as a period for measuring the usage time of the liquid crystal display device 10 or the like. is there. Further, in the case where the memory for storing the total usage time data is constituted by a ferroelectric memory instead of the EEPROM, the number of times of writing is guaranteed about 10 million times, so that the above-described INT interrupt processing is executed. The fixed time interval may be set to about 10 seconds, for example. In such a case, the measurement error can be reduced by shortening the measurement interval of the usage time of the liquid crystal display device 10 or the like, and more accurate measurement of the total usage time can be executed.

  FIG. 6 is a flowchart of a usage time display process executed on the display control board D of the pachinko machine 1. In this usage time display processing, the total usage time data of the units corresponding to the pressed switches 50a to 50d is read from the memories 43a to 43d of the EEPROM 43 and displayed on the display LED 49, or the total usage time data is cleared. Process. The usage time display process is one of the processes that are periodically and repeatedly executed on the display control board D.

  In the usage time display process, first, it is determined whether any of the switches 50a to 50d has been pressed (S21). As a result, when none of the switches 50a to 50d has been pressed (S21: No), this process ends.

  If it is determined in the process of S21 that any one of the switches 50a to 50d has been pressed (S21: Yes), the pressed switches are the liquid crystal panel switch 50a, the backlight switch 50b, and the display control board switch. Whether it is 50c or the liquid crystal control board switch 50d is confirmed (S22). When the pressed switch is the liquid crystal panel switch 50a (S22: liquid crystal panel switch), the process to be executed is the process of displaying the usage time of the liquid crystal panel 53 on the display LED 49 or the total use of the liquid crystal panel 53. This is a process of clearing data in the liquid crystal panel memory 43a of the EEPROM 43 in which time data is stored. Therefore, in such a case, the display of the usage time of the liquid crystal panel 53 or the clear of the total usage time data is executed by the liquid crystal panel switch process (S23). And after performing the process of S23, this use time display process is complete | finished.

  On the other hand, in the process of S22, when the pressed switch is the backlight switch 50b (S22: backlight switch), the process to be executed is a process of displaying the usage time of the backlight 54 on the display LED 49, or This is a process of clearing the data in the backlight memory 43b of the EEPROM 43 in which the total use time data of the backlight 54 is stored. Therefore, in such a case, display of the usage time of the backlight 54 or clearing of the total usage time data is executed by the backlight switch process (S24). And after performing the process of S24, this use time display process is complete | finished.

  In the process of S22, when the pressed switch 50 is the display control board switch 50c (S22: display control board switch), the process to be executed displays the usage time of the display control board D on the display LED 49. Or clearing the data in the display control board memory 43c of the EEPROM 43 in which the total use time data of the display control board D is stored. Therefore, in such a case, display of the usage time of the display control board D or clearing of the total usage time data is executed by the display control board switch process (S25). And after performing the process of S25, this use time display process is complete | finished.

  In the process of S22, when the pressed switch 50 is the liquid crystal control board switch 50d (S22: liquid crystal control board switch), the process to be executed is a process of displaying the usage time of the liquid crystal control board L on the display LED 49, Alternatively, it is a process of clearing the data in the liquid crystal control board memory 43d of the EEPROM 43 in which the total use time data of the liquid crystal control board L is stored. Therefore, in such a case, the display of the usage time of the liquid crystal control board L or the clearing of the total usage time data is executed by the liquid crystal control board switch process (S26). And after performing the process of S26, this use time display process is complete | finished.

  Here, the liquid crystal panel switch process that is the process of S23 is a process that is executed according to the flowchart shown in FIG. 7, and the backlight switch process that is the process of S23 is a process that is executed according to the flowchart shown in FIG. .

  FIG. 7 is a flowchart showing a liquid crystal panel switch process executed on the display control board D of the pachinko machine 1. The liquid crystal panel switch process (S23) is executed when the liquid crystal panel switch 50a is pressed, and the usage time of the liquid crystal panel 53 is displayed on the display LED 49 or stored in the liquid crystal panel memory 43a of the EEPROM 43. This is a process for clearing 53 total use time data. In the present embodiment, the liquid crystal panel 53 whose lifetime guarantee time is 40,000 hours will be described.

  In the liquid crystal panel switch process, first, the pressed state of the liquid crystal panel switch 50a is confirmed (S31). When the pressing time of the liquid crystal panel switch 50a is less than 5 seconds (S31: No), the value of the total usage time data stored in the liquid crystal panel memory 43a of the EEPROM 43 by the processes of S32, S33, and S34 And the number of LEDs (light emission number) of the display LED 49 is changed by each process of S35, S36, and S37. When the total use time data value of the liquid crystal panel 53 stored in the liquid crystal panel memory 43a of the EEPROM 43 is 40,000 hours or more (S32: Yes), all the LEDs of the display LED 49, that is, the third LED 49c and the second LED 49b. Then, all the first LEDs 49a are turned on (S35, S36, S37), and this state is kept waiting for 5 seconds (S38: No). The operator can confirm that the liquid crystal panel 53 has been used for more than 40,000 hours, which is the guaranteed lifetime, since all the LEDs of the display LED 49 are lit. You can know that it is already time for replacement. When 5 seconds have elapsed since the display LED 49 started to turn on (S38: Yes), each LED of the display LED 49 is turned off (S39), and the liquid crystal panel switch processing is ended.

  On the other hand, when the total use time data value of the liquid crystal panel 53 stored in the liquid crystal panel memory 43a of the EEPROM 43 is 20,000 hours or more and less than 40,000 hours (S32: No, S33: Yes), the display LED 49 Among the LEDs, the second LED 49b and the first LED 49a are turned on (S36, S37), and this state is maintained for 5 seconds (S38: No). Since the two LEDs of the display LED 49 are lit, the operator says that the liquid crystal panel 53 has not reached 40,000 hours, which is the guaranteed lifetime, but has already been used for more than 20,000 hours. I can confirm that. For example, when the liquid crystal display device 10 is reused for another pachinko machine, the liquid crystal panel 53 can be replaced with a new one to prevent problems with the liquid crystal panel. When 5 seconds have elapsed since the display LED 49 started to turn on (S38: Yes), each LED of the display LED 49 is turned off (S39), and the liquid crystal panel switch processing is ended.

  When the total use time data value of the liquid crystal panel 53 stored in the liquid crystal panel memory 43a of the EEPROM 43 is 10,000 hours or more and less than 20,000 hours (S32: No, S33: No, S34: Yes), display is performed. Of the LEDs 49, only the first LED 49a is turned on (S37), and this state is maintained for 5 seconds (S38: No). The operator can confirm that the usage time of the liquid crystal panel 53 is 10,000 hours or more and less than 20,000 hours because only one LED of the display LED 49 is lit. When 5 seconds have elapsed since the display LED 49 started to turn on (S38: Yes), each LED of the display LED 49 is turned off (S39), and the liquid crystal panel switch processing is ended.

  When the total use time data value of the liquid crystal panel 53 stored in the liquid crystal panel memory 43a of the EEPROM 43 is less than 10,000 hours (S32: No, S33: No, S34: No), the display LED 49 is turned on. Without this, the liquid crystal panel switch process is terminated. Therefore, when the operator depresses the liquid crystal panel switch 50a but the display LED 49 does not light, the usage time of the liquid crystal panel 53 is less than 10,000 hours, and the liquid crystal panel 53 has a sufficient remaining life. It can be confirmed.

  In the process of S31, when the pressing time of the liquid crystal panel switch 50a is 5 seconds or more (S31: Yes), the total use time data stored in the liquid crystal panel memory 43a of the EEPROM 43 is cleared to “0” (S40). ). As described above, the total use time data of the liquid crystal panel memory 43a is not cleared unless the liquid crystal panel switch 50a is continuously pressed for 5 seconds or more, so that it is prevented from being cleared by an inadvertent erroneous operation by the operator. it can. For example, when the liquid crystal panel 53 that has reached the end of its life is removed from the liquid crystal display device 10 and replaced with a new liquid crystal panel, the total use time data in the liquid crystal panel memory 43a is cleared to “0” by the above operation. With this clear operation, the usage time of the newly mounted liquid crystal panel can be measured from “0”.

  After executing the process of S40, the first to third LEDs 49a to 49c of the display LED 49 are simultaneously blinked at predetermined time intervals (S41), and the liquid crystal display is kept waiting for 5 seconds while keeping such a state (S38: No). The operator is informed that the total use time data in the panel memory 43a is cleared to “0”. When 5 seconds have elapsed after the blinking of the display LED 49 (S38: Yes), each LED of the display LED 49 is turned off (S39), and this liquid crystal panel switch process is terminated.

  FIG. 8 is a flowchart showing a backlight switch process executed on the display control board D of the pachinko machine 1. The backlight switch process (S24) is executed when the backlight switch 50b is pressed, and the usage time of the backlight switch 54 is displayed on the display LED 49 or stored in the backlight memory 43b of the EEPROM 43. This is a process for clearing the total use time data of the write 54. In this embodiment, the backlight 54 whose lifetime guarantee time is 10,000 hours will be described. Also, the same step numbers are assigned to the same processes as those in the liquid crystal panel switch process shown in FIG. 7, and the description thereof is omitted.

  In the backlight switch process, first, the pressing state of the backlight switch 50b is confirmed (S51). When the pressing time of the backlight switch 50b is less than 5 seconds (S51: No), the value of the total usage time data stored in the backlight memory 43b of the EEPROM 43 by each process of S52, S53, and S54 And the number of LEDs (light emission number) of the display LED 49 is changed by each process of S35, S36, and S37. When the total usage time data value of the liquid crystal panel 53 stored in the backlight memory 43b of the EEPROM 43 is 10,000 hours or more (S52: Yes), all the LEDs of the display LED 49, that is, the third LED 49c and the second LED 49b. Then, all the first LEDs 49a are turned on (S35, S36, S37), and this state is kept waiting for 5 seconds (S38: No). Since all the LEDs of the display LED 49 are lit, the operator can confirm that the backlight 53 has been used for more than 10,000 hours, which is the lifetime guarantee time. You can know that it is already time for replacement. When 5 seconds have elapsed since the lighting of the display LED 49 is started (S38: Yes), each LED of the display LED 49 is turned off (S39), and the backlight switch process is ended.

  On the other hand, when the total use time data value of the backlight 54 stored in the backlight memory 43b of the EEPROM 43 is 4000 hours or more and less than 7000 hours (S52: No, S53: Yes), the LED of the display LED 49 Among them, the second LED 49b and the first LED 49a are turned on (S36, S37), and this state is continued for 5 seconds (S38: No). Since the two LEDs of the display LED 49 are lit, the operator does not reach 10,000 hours, which is the guaranteed lifetime, but has already been used for more than 7000 hours. Can be confirmed. For example, the total usage time of the backlight 54 of each pachinko machine is periodically checked, and when the backlight 54 that has been used for more than 7000 hours is found, it is replaced with a new one. It is possible to prevent a malfunction of the backlight 54. When 5 seconds have elapsed since the lighting of the display LED 49 is started (S38: Yes), each LED of the display LED 49 is turned off (S39), and the backlight switch process is ended.

  When the value of the total use time data of the backlight 54 stored in the backlight memory 43b of the EEPROM 43 is 4000 hours or more and less than 7000 hours (S52: No, S53: No, S54: Yes), the display LED 49 Of the LEDs, only the first LED 49a is turned on (S37), and this state is continued for 5 seconds (S38: No). Since only one LED of the display LED 49 is lit, the operator can confirm that the usage time of the backlight 54 is 4000 hours or more and less than 7000 hours. When 5 seconds have elapsed since the lighting of the display LED 49 is started (S38: Yes), each LED of the display LED 49 is turned off (S39), and the backlight switch process is ended.

  When the total use time data value of the backlight 54 stored in the backlight memory 43b of the EEPROM 43 is less than 4000 hours (S52: No, S53: No, S54: No), the display LED 49 is turned on. The backlight switch process is terminated without any processing. Therefore, when the operator presses the backlight switch 50b and the display LED 49 does not light, the operator confirms that the usage time of the backlight 54 is less than 4000 hours and the backlight 54 has a sufficient remaining life. It can be done.

  In the liquid crystal panel switch processing (see FIG. 7), all the display LEDs 49 are turned on when the total usage time of the liquid crystal panel 53 is 40,000 hours or more. In this case, as described above, all the display LEDs 49 are turned on when the total usage time is 10,000 hours or more. Thus, the ratio between the value of the total usage time of the unit and the number of light emission of the LED to emit light is changed according to the type of unit. Therefore, since the number of LEDs used for the display LED 49 can be reduced, the apparatus can be simplified and the apparatus cost can be reduced.

  On the other hand, in the process of S51, when the pressing time of the backlight switch 50b is 5 seconds or more (S51: Yes), the total use time data stored in the backlight memory 43b of the EEPROM 43 is cleared to “0”. (S55). Then, after the process of S40 is performed, the first to third LEDs 49a to 49c of the display LED 49 are simultaneously blinked at predetermined time intervals for 5 seconds in the same manner as the liquid crystal panel switch process (see FIG. 7) (S41). , S38: Yes), each LED of the display LED 49 is turned off (S39), and the backlight switch process is terminated.

  As described above, the total usage time in which the liquid crystal display device 10 is actually used is displayed on the display LED 49 for each unit. Therefore, the usage time for each unit can be grasped quantitatively, and the liquid crystal display device 10 can be reused efficiently.

  Next, a second embodiment will be described with reference to FIG. In the pachinko machine 1 of the first embodiment, the total use time of each unit is displayed by the display LED 49 configured by LEDs, whereas in the pachinko machine 1 of the second embodiment, the operation is performed by a solenoid. The total usage time of each unit is displayed by a mechanical counter. In addition, the same code | symbol is attached | subjected to the part same as the above-mentioned 1st Example, and the description is abbreviate | omitted.

  FIG. 9 is an exploded perspective view showing the liquid crystal display device 60 mounted on the pachinko machine 1 in the second embodiment for each unit. In FIG. 9, only main constituent units of the liquid crystal display device 60 are illustrated, and the other components are not illustrated for simplicity. As in the case of the first embodiment, the liquid crystal display device 60 is mainly composed of units such as the liquid crystal panel 53, the backlight 54, and the liquid crystal control board L, and each unit is electrically detachable. It is connected. A mechanical counter 61 is detachably juxtaposed with screws on the outer surface (right side in FIG. 9) of the upper case 57a of the case 57 that stores the liquid crystal panel 53 and the like. The mechanical counter 61 is for displaying the total usage time for each unit on the display unit 66. The liquid crystal panel mechanical counter 61a, the backlight mechanical counter 61b, the display control board mechanical counter 61c, and the liquid crystal And a control board mechanical counter 61d. These mechanical counters 61a to 61d are electrically connected to the display control board D in a detachable manner by connectors 62 to 65 provided on the display control board D. When the count-up signal is transmitted from the display control board D, each of the mechanical counters 61a to 61d increases the numerical value of the display unit 66 by the operation of the solenoid, and the display value of the display unit 66 is the power supply It is maintained after the supply is cut off.

  The mechanical counter 61 includes a display unit 66 and a change switch 67. The display unit 66 is for displaying the total usage time of each unit, and includes six rotating rollers on which the numerical values “0 to 9” are printed at predetermined intervals on the outer peripheral surface. A 6-digit numerical value is displayed by rotating by operation. The unit of the numerical value displayed on the display unit is “time”. The reset switch 67 disposed on the side of the display unit 66 (upper side in FIG. 9) is a push button that can be pressed. By pressing the reset switch 67, the numerical value of each digit of the display unit 66 is changed. It can be set to “0”. For example, when it is discovered by regular inspection or the like that the backlight 54 has reached the lifetime guarantee time, and the backlight 54 is replaced with a new one, the reset switch 67 of the backlight mechanical counter 61b is set. Press. By such pressing, the total usage time of the backlight 54 can be newly measured from “0”.

  When the liquid crystal display device 60 removed from the recovered pachinko machine 1 is diverted to another pachinko machine, can the unit be reused by checking the display values of the mechanical counters 61a to 61d? It is possible to determine whether or not (that is, a quantitative value of the remaining lifetime). In this case, the total usage time of each unit is maintained in each of the mechanical counters 61a to 61d even if power is not supplied. That is, the display values of the mechanical counters 61a to 61d are visible without supplying power. For example, when only the liquid crystal panel 53 is diverted to another pachinko machine, the liquid crystal panel mechanical counter 61a that displays the total use time of the liquid crystal panel 53 is also diverted at the same time, so that the value of the total use time of the liquid crystal panel 53 is obtained. Can be diverted while maintaining (memory).

  FIG. 10 is a block diagram showing an electrical configuration of the pachinko machine 1 in the second embodiment. In the second embodiment, the total usage time of each unit is displayed by the mechanical counter 61 instead of the display LED 49 (see FIG. 3) in the first embodiment. Further, since the mechanical counter 61 includes the number of mechanical counters 61a to 61d corresponding to each unit, the EEPROM 43 and the switch 50 in the first embodiment are not provided.

  Similar to the first embodiment, the display control board D mainly includes an MPU 41, a ROM 42, a work RAM 71, a video RAM 45, a character ROM 46, an image controller 47, an input / output port 48, and a gate array 70. And. The input of the input / output port 48 is connected to the output of the main control board C, and the output of the input / output port 48 is connected to the bus line 51 for connecting the MPU 41, ROM 42, work RAM 71, and image controller 47. The mechanical counter 61 and the liquid crystal display device 10 are connected to the output of the input / output port 48 via connectors 62 to 65 and a connector 52, respectively.

  The work RAM 71 is a memory for temporarily storing work data used when various programs are executed by the MPU 41, and includes an interval counter 71a. The interval counter 71a is a memory for storing time data that is added every fixed time by the MPU 41. When this time data exceeds a predetermined value, a count-up signal to the mechanical counter 61 is output by the MPU 41.

  The mechanical counter 61 is for displaying the total usage time of each unit, and includes a liquid crystal panel mechanical counter 61a, a backlight mechanical counter 61b, a display control frame mechanical counter 61c, and a liquid crystal control board mechanical counter 61d. And. Each of the mechanical counters 61a to 61d is detachably connected to the input / output port 48 of the display control board D via connectors 62 to 65, respectively, and when a count-up signal transmitted by the MPU 41 is input, The display value displayed on the display unit 66 (see FIG. 9) of the mechanical counters 61a to 61d increases by “1” (for one hour).

  FIG. 11 is a flowchart showing a main process executed in the display control board D of the pachinko machine 1 in the second embodiment. By this main process, each process necessary for the display control board D, such as control of image display, is executed. The same step numbers are assigned to the same processes as those in the first embodiment. In this main process, first, as in the first embodiment, after the power is turned on, an initialization process is executed such that the contents of the work RAM 44 and the like are once cleared to "0" and then set to an initial value (S1). After execution of the initialization process of S1, “180” is added to the time data stored in the interval counter 71a of the work RAM 71 (S81). As will be described later (see FIG. 12), time data “1” is added every 10 seconds to the interval counter 71a of the work RAM 71, and the time data becomes “360” (one hour) or more. In addition, a count-up signal for increasing the display by one hour is transmitted to each of the mechanical counters 61a to 61d. Therefore, every time the power of the pachinko machine is turned off, time data ("0" to "360") added to the interval counter 71a of the work RAM 71 between the time when the last count-up signal is transmitted and the time when the power is turned off. Will not be measured. Although the value of the time data that is not measured is different every time the power is turned off, the time data corresponding to an average of “180” is not measured, and there is a problem that the reliability of the measured total use time of the liquid crystal display device 10 is lowered. . Therefore, by executing the process of S81 each time the power is turned on, the measurement error accumulated when the power is turned off can be adjusted, and the accurate total usage time can be measured. In the present embodiment, the time data to be added in the process of S81 is the average value “180” of the measurement error (range “0” to “360”) that occurs when the power is turned off. Large time data may be added. For example, when the time data “360” is configured to be added, it is possible to manage the usage time of the unit having a sufficient margin. And after execution of the process of S2, each process performed with the display control board D is repeated (S3).

  FIG. 12 is a flowchart showing an INT interrupt process executed every 10 seconds on the display control board D of the pachinko machine 1 in the second embodiment. This INT interruption process is a process for measuring the usage time of the liquid crystal display device 10 or the like and displaying the total usage time on the mechanical counter 61. Regarding this INT interrupt processing, the CPU 41 adds “1” to the time data stored in the interval counter 71a of the work RAM 71 and updates the time data (S91). After executing the processing of S91, it is determined whether or not the value of the time data stored in the interval counter 71a of the work RAM 71 is equal to or greater than “360” (S92). As a result of the determination, when the value of the time data is “360” or more (S92: Yes), since one hour has passed since the display of each mechanical counter 61a to 61d was updated last time, By outputting a count-up signal to the mechanical counters 61a to 61d (S93), the display of each mechanical counter 61a to 61d is updated for one hour. Thereafter, the value of the time data stored in the interval counter 71a of the work RAM 71 is cleared to “0” (S94), and this INT interrupt process is terminated. This INT interrupt process is periodically repeated every 10 seconds while the power is turned on. Thereby, the display of each mechanical counter 61a-61d is updated every hour, and the total use time of each unit can be grasped | ascertained quantitatively by confirming this display.

  In this way, by providing the mechanical counters 61a to 61d as many as the number corresponding to the unit that determines reuse, it is possible to determine which unit can be reused without supplying power. Can do it.

  Note that the usage time of each unit described in each of the above embodiments refers to the time during which each unit actually operates by supplying power, that is, the energization time.

  The present invention has been described based on the embodiments. However, the present invention is not limited to the above embodiments, and various modifications can be easily made without departing from the spirit of the present invention. It can be guessed.

  For example, in the first embodiment, the measured use time of the liquid crystal display device 10 and the like is accumulated and stored as the total use time in each of the memories 43a to 43d of the EEPROM 43. Instead of this, each memory of the EEPROM 43 is stored. 43a to 43d are stored individually in advance for the guaranteed use time of the liquid crystal display device 10 and the like, and the remaining use time of each device is subtracted from the stored use guaranteed time value. You may comprise so that it may memorize | store as time. In such a case, the number of display LEDs 49 may be configured so that all the LEDs are initially lit, and the number of display LEDs 49 may be decreased as the remaining life time decreases. The operator can easily recognize the remaining lifetime remaining in each device by visually recognizing the number of lighting of the display LEDs 49.

  In each of the above-described embodiments, the display device using liquid crystal has been described as the display device. However, the display device is not necessarily limited to this, and a display device using a CRT (CRT) may be used instead. It is.

  Further, in the first embodiment, the total usage time stored in each memory of the EEPROM 43 is configured to be displayed on the display LED 49, but the total usage time of the unit corresponding to the pressed switch 50 is displayed. Instead of this, it may be configured to be displayed on the liquid crystal display device 10. In this case, the total usage time of all the units stored in each memory of the EEPROM 43 may be displayed simultaneously regardless of which switch 50 is pressed. By utilizing the wide display area of the liquid crystal display device 10, the total usage time of each unit can be displayed at the same time, improving the workability of the operator's confirmation work.

  Further, the timing for displaying the total usage time stored in each memory of the EEPROM 43 is not limited to the case where the switch 50 provided on the display control board D is pressed. Even when it is received, the display on the liquid crystal display device 10 may be executed. That is, by further providing a device capable of transmitting a display command command to the display control board D by operating a switch or the like, the total usage time of each unit can be confirmed while the gaming machine 1 is installed in the gaming hall or the like. Can be executed. A display command command may be transmitted from the main control board C to the display control board D at a predetermined timing. Further, for example, when the power is turned on, the total use time stored in each memory of the EEPROM 43 may be displayed on the liquid crystal display device only for a predetermined time. In this case, the total usage time of each unit of the liquid crystal display device can be confirmed without performing complicated work.

  Further, in the first embodiment, the display LED 49 including three LEDs has been described as a device for displaying the total usage time of each unit, but instead of this, the total use is made by using a 7-segment LED. You may comprise so that time may be displayed as a number. In this case, for example, “1” is displayed when the total use time is less than 10,000 hours, and “2” is displayed when the total use time is 10,000 hours or more and less than 20,000 hours.

  The modification of this invention is shown below. 2. The gaming machine according to claim 1, wherein the display device is composed of two or more units that are electrically connected to each other and are separable, and the usage time storage means is measured by the usage time measurement means. Operates the unit usage time storage means for storing the usage time of the display unit for each unit, the clear means for clearing the usage time of each unit stored in the unit usage time storage means for each unit, and the clear means And a clear operation means for causing the usage time display means to include a unit usage time display means for displaying the usage time of each unit stored in the unit usage time storage means. . Accordingly, since the usage time of the display device can be confirmed for each unit constituting the display device, each unit having a different lifetime can be efficiently reused. For example, when the display device is removed from the collected gaming machine and reused for another gaming machine, it can be confirmed by the unit usage time display device whether the life of each unit has been reached. Therefore, if there is a unit that has reached the end of its life, only that unit can be replaced. In this case, the usage time of the replaced unit is newly measured from zero by clearing only the usage time of the replaced unit from the usage times stored in the unit usage time storage means. Other units can continue to measure their usage time as they can begin. Therefore, the usage time for each unit can be accurately measured.

  In the gaming machine 1, the clear operation means is configured by the same number of clear switches as the unit, and the clear means clears the use time of the unit corresponding to the operated clear switch from the unit use time storage means. A gaming machine 2 characterized by this. Since the clear operation means is provided for each unit, the operator can clear the use time only by operating the clear operation means corresponding to each unit without performing complicated work.

  In the gaming machine 1 or 2, the clearing unit operates when the clear switch is operated continuously for a predetermined time or more. If the clearing means is activated simply by operating the clear switch, the contents stored in the unit usage time recording means are cleared by the clearing means due to careless operation by the operator. On the other hand, the gaming machine 3 is configured such that the clearing unit is activated when the clearing switch is operated for a predetermined time or longer, so that the clearing unit can be operated even if the operator operates the clearing switch by careless operation. Does not operate and the contents of the unit usage time recording means can be retained. Therefore, the operation of the clearing means due to an erroneous operation or the like can be avoided, and the usage time of each unit can be reliably stored.

  In any one of the gaming machines 1 to 3, the unit usage time display means selects a usage time to be displayed from the usage times of each unit stored in the unit usage time storage means, and displays the selected usage time. A gaming machine 4 comprising: unit selection display means for operating and unit selection display operation means for operating the unit selection display means. Since the unit selection display means can select which unit's usage time is to be displayed from among the units, the single unit selection display means can display the usage time of each unit. Therefore, since it is not necessary to provide a device for displaying the usage time for each unit, the device can be simplified and the device cost can be reduced.

  In the gaming machine 4, the display device includes a switch unit that selectively activates the clearing unit and the unit selection display unit, wherein one switching unit includes two units ( Since it is shared as an operation switch for the clearing unit and the unit selection display unit), the device can be simplified and the device cost can be reduced by the amount that one switch unit can be omitted.

  In the gaming machine 5, the switch means is constituted by a push button, the unit selection display means is activated when the push button is continuously pushed for a first predetermined time, and the clear means pushes the push button. A gaming machine 6 that operates when the button is continuously pressed for a second predetermined time longer than the first predetermined time. Since the clearing means can only operate when pressed for a second predetermined time longer than the first predetermined time, the clearing means can be prevented from being easily operated even by an operator's inadvertent misoperation. be able to.

  In any one of the gaming machines 1 to 6, the unit usage time display means includes a plurality of light emitters configured to be capable of emitting light, and the plurality of unit usage time display means according to a value of usage time stored in the unit usage time storage means. A gaming machine comprising a light emission display means capable of increasing or decreasing the number of light emission of the light emitters. Since the usage time is displayed according to the number of light emission of the light emitter, the usage time can be easily recognized by confirming the number of light emission of the light emitter. Further, the apparatus can be simplified and the apparatus cost can be reduced as compared with the case where the usage time is displayed using numerals.

  In the gaming machine 7, the light emission display means includes light emission changing means for changing a ratio between the value of the usage time and the number of light emission of the light emitting body to emit according to the type of the unit for which the usage time is displayed. A gaming machine 8 characterized by that. Even when the lifespan of each unit is greatly different, the usage time of the unit having the longest lifespan can be displayed with a smaller number of light emitters. Therefore, the apparatus can be simplified and the apparatus cost can be reduced by the amount that the increase in the number of light emitters can be prevented.

  In the gaming machine 7 or 8, the light emitter is constituted by an LED. By using an LED having a low cost and excellent lifetime characteristics, the device cost can be reduced and a stable usage time can be displayed.

  In the gaming machine 1, the unit usage time storage means includes addition means for adding a predetermined time to the usage time value stored for each unit when the power is turned on. Machine 9. Since the error in usage time accumulated every time the power is turned off can be adjusted, the usage time can be accurately measured.
