  Command transmission from the main board to the sub board is performed by serial transmission. For this reason, the generated command is once stored in a buffer (register) and then sent to the shift register to perform parallel-serial conversion. If the command is directly written to the shift register by the CPU, the CPU cannot wait during the operation of the shift register, so that the CPU waits and the processing efficiency deteriorates. For this reason, a buffer is used. Although the input side of this buffer is controlled by the CPU and the output side is connected to the shift register, the operations of both are not synchronized. There is a FIFO (First In First Out) as a buffer used when writing and reading are not synchronized. This is a buffer that can sequentially read out written data in the order of writing, and is often used when data is exchanged between subsystems that are not synchronized. The FIFO is suitable as a buffer device for command transmission from the main board to the sub board.

  By the way, in the gaming machine, when the power is turned on without pressing the clear button, the state immediately before the power is turned off is restored. That is, even if the power is turned on / off, the state of the gaming machine such as the winning flag does not change.

  However, the contents of the command transmission buffer (FIFO) are lost due to the power interruption, and are not backed up. If it is data in a memory such as RAM, it is backed up after the power is turned off until the power supply voltage actually drops and the operation of the CPU stops, and the backed up data when the power is turned on is developed in the memory In this case, the state immediately before the power-off can be restored, but this is not done for the command transmission buffer (FIFO). In general, the FIFO has only two terminals, an input end and an output end, and does not have means for backing up data of each of a plurality of registers (latches) in the FIFO. For this reason, the transmission command from the main board to the sub board is not backed up, and the command is lost when the power is turned off. In the conventional gaming machine, the command cannot be restored to the state immediately before the power is turned off.

  An object of the present invention is to provide a gaming machine capable of performing backup at the time of power-off for a command transmission buffer.

This is an apparatus for selecting and removing illegal medals made of an alloy and selecting and eliminating a predetermined number or more of medals that can be inserted per game.

  Further, as shown in FIG. 2, a lead-out path 136 that covers the lower side and communicates with the payout port 135 of the front door 130 is provided below the medal selector 1. The medals distributed by the medal selector 1 are returned to the player from the payout port 135 via the derivation path 136.

FIG. 3 shows a functional block diagram of the slot machine 100 according to the embodiment of the invention.
In this figure, the display about the power supply system is omitted. Although not shown, the slot machine includes a power supply unit for generating a DC power supply (+5 V or the like) from a commercial power supply (AC 100 V).
The slot machine 100 includes a main substrate (processing unit) 10 and a sub substrate 20 that operates in response to a command from the main substrate (processing unit) 10 as main processing devices. At least the main substrate 10 is accommodated inside the case so that it cannot be contacted from the outside, and is sealed so that traces remain when these substrates are removed.

  The main board 10 is used for performing an internal lottery in response to a player's operation, and for performing processing such as rotation / stop of the spinning cylinder and payout of medals. The main board 10 includes a CPU that performs a control operation according to a preset program, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like.

  The sub board 20 is for receiving a command signal from the main board 10 and notifying the result of the internal lottery and performing various effects. The sub-board 20 includes a CPU that performs a control operation in accordance with a preset program corresponding to the command signal, a ROM that is a storage unit that stores the program, and a RAM that temporarily stores processing results and the like. Only one command flows from the main board 10 to the sub board 20, and conversely, no command is issued from the sub board 20 to the main board 10.

  The main board 10 has a bet switch BET, a start switch 134, a stop button 140, a reel (rotating cylinder) unit 203, a hopper driving unit 80, a hopper 81, and a medal detection for counting the number of medals paid out from the hopper 81. The part 82 (these 80, 81, and 82 comprise the above-mentioned hopper apparatus 121) is connected. A peripheral substrate (local substrate) such as a liquid crystal control substrate 200 for controlling the liquid crystal display device, a speaker substrate 201, and an LED substrate 202 is connected to the sub substrate 20.

  A liquid crystal display device LCD shown in FIG. 1 is connected to the liquid crystal control board 200. In the following description, unless otherwise specified, the liquid crystal display device LCD refers to both the liquid crystal control substrate 200 and the liquid crystal display device LCD (in other words, the liquid crystal display device LCD is a liquid crystal control substrate). 200).

  Further, medal sensors S1 and S2 of the medal selector 1 are connected to the main board 10.

  The medal selector 1 is provided with medal sensors S1 and S2 for counting medals. The medal sensors S1 and S2 are provided on the downstream side (near the exit) of a medal passage (not shown) provided in the medal selector 1 (the upstream side of the medal passage communicates with the medal slot 132). The two medal sensors S1 and S2 are arranged side by side at a predetermined interval along the medal traveling direction. The medal sensors S1 and S2 are, for example, photointerrupters that have a light emitting portion and a light receiving portion that face each other, are formed in a U-shaped cross section, and are positioned so that the detection optical axis faces the medal passage from above. . Each photo interrupter detects the passage of a medal sent without being blocked on the way. The reason why two photo interrupters are adjacent is not only to detect the number of medals but also to monitor whether or not the passage of medals is normal. That is, by providing two photo interrupters adjacent to each other, it is possible to detect the passing speed and passing direction of medals, thereby detecting not only the number of medals but also an illegal act moving in the reverse direction.

  The reel unit 203 includes three spinning cylinders 40a to 40c, stepping motors 155a to 155c that respectively rotate these, and spinning cylinder position detectors 159a to 159c that detect their positions, respectively (stepping motor 155a ˜155c may be simply referred to as a motor 155 or a motor).

  The hopper driving unit 80 rotates the hopper 81 and performs an operation of paying out medals of the payout number instructed by the main board 10. The gaming machine includes a medal detection unit 82 that operates every time a medal is paid out, and the main board 10 receives a medal actually paid out from the hopper 81 based on an input signal from the medal detection unit 82. You can manage the number.

  The insertion accepting unit 1050 receives the outputs of the medal sensors S1 and S2 of the medal selector 1, accepts the insertion of medals for each game, and determines that the medal corresponding to the specified number of insertions has been inserted. A process of permitting the rotation start operation of the first cylinder to the third cylinder is performed. Note that the pressing operation of the start switch 134 is an opportunity to start the rotation of the first cylinder to the third cylinder, and is an opportunity to execute the internal lottery. Also, a prescribed number of throws is set according to the gaming state, the prescribed number of throws is set to 3 in the normal state and the bonus established state, and the prescribed number of throws is set to 1 in the bonus state.

  When medals are inserted, the inserted medals are set in a bet state, up to the specified number of insertions according to the gaming state. Alternatively, when the bet switch BET is pressed in a state where medals are credited to the gaming machine, the credited medals are set to the bet state by limiting the specified number of insertions according to the gaming state. The main board 10 controls whether or not to accept a medal. From the point when the start switch 134 is pressed and the rotation of each cylinder starts (game start time), when the three stop switches 140 are pressed and the rotation of each cylinder stops (when the medal payout is completed when winning) (game) When the medal is not accepted (when it is not permitted), the medal sensor S1, S2 does not count the medal and is returned as it is. . Similarly, the main board 10 controls the validity / invalidity of the bet switch BET according to whether or not the medal insertion is accepted. In addition, the bet switch BET is valid from the end of the game to the start of the game, but during other periods (when pressing of the BET switch is not permitted), the bet switch BET is pressed. Even it is ignored.

  The main board 10 incorporates random number generating means 1100. The random number generation means 1100 is a means for generating a random number for lottery. The random value can be generated based on, for example, a count value of an increment counter (a counter that counts a numerical value so as to circulate a predetermined count range). In this embodiment, the “random number value” is not only a value that is randomly generated in a mathematical sense, but even if the generation itself is regular, the acquisition timing and the like are irregular. Includes a value that can function as a random number.

  The internal lottery means 1200 performs an internal lottery in which the player determines whether or not the winning combination is based on a start signal from the start switch 134. That is, a lottery table selection process for selecting a lottery table (not shown) stored in a memory (not shown) of the main board 10, a random number determination process for determining the winning of a random number obtained from the random number generating means 1100, The lottery flag setting process for setting a flag to that effect when a big win or the like is won by the determination result is performed.

  In the lottery table selection process, a lottery table (not shown) stored in a storage unit (ROM) (not shown) is used to determine which lottery table is used for internal lottery. In the lottery table, for each of a plurality of random values (for example, 65536 random values from 0 to 65535), replay, small role (bell, cherry), regular bonus (RB: bonus), and big bonus (BB :), etc., are associated with each other. In addition, a normal state, a bonus establishment state, and a bonus state can be set as the gaming state, and a replay lottery state, a replay low probability state, and a replay high probability state can be set as replay lottery states.

  In the random number determination process, a random value (lottery random number) is acquired from the random number generation means (not shown) for each game based on a start signal from the start switch 134, and the lottery table is referred to for the acquired random value. Then, it is determined whether or not the winning combination is won.

  In the lottery flag setting process, the lottery flag of the winning combination determined to be won based on the result of the random number determination process is changed from the non-winning state (first flag state, off state) to the winning state (second flag state, on Status). When two or more types of winning combinations are won, a lottery flag corresponding to each of the two or more types of winning winning combinations is set to the winning state. The lottery flag setting information is stored in storage means (RAM).

  A lottery flag (possible carryover flag) that can carry over the winning state for the next game until winning, and a lottery flag that is reset to the non-winning state without bringing the winning state to the next game regardless of winning Carry-over impossible flag) may be provided. In this case, there are a regular bonus (RB) and a big bonus (BB) as a combination to which the former carry-over possible flag is associated, and other combinations (for example, small role, replay) correspond to the latter carry-over impossible flag. It is attached.

  In other words, in the lottery flag setting process, if a regular bonus is won by internal lottery, the winning state of the regular bonus lottery flag is carried over until the regular bonus is won, and if the big bonus is won by internal lottery, the big bonus lottery A process of carrying over the winning state of the flag until the big bonus is won is performed. At this time, the main board 10 determines whether or not a role other than the regular bonus and the big bonus (small role and replay) is used even in a game in which the winning state of the regular bonus or big bonus lottery flag is carried over by the internal lottery function. An internal lottery is performed. In other words, in the lottery flag setting process, in a game in which the winning state of the regular bonus lottery flag is carried over, if a small role or replay is won in the internal lottery, the regular bonus lottery flag and the internal lottery already won In a game in which the lottery flags corresponding to two or more types of winning combinations or replay lottery flags won in the win state are set to the winning state and the winning state of the big bonus lottery flag is carried over, it is small in the internal lottery When a winning combination or replay is won, a lottery flag corresponding to two or more kinds of winning combinations including a big bonus lottery flag that has already been won and a small bonus or replay lottery flag that has been won in the internal lottery is set to the winning state Set.

  The spinning cylinder control means 1300 rotates the first to third cylinders with a stepping motor based on a start signal generated by a player pressing the start switch 134 (rotation start operation), and the first to Press operation (stop operation) of the three stop buttons 140 respectively corresponding to the rotating cylinder in a state where the rotation speed of the third cylinder reaches a predetermined speed (about 80 rpm: a rotation speed of about 80 rotations per minute) ) And control to stop the first to third cylinders driven to rotate by the stepping motor according to the lottery flag setting state (internal lottery result).

  In addition, when the player presses the three stop buttons 140 in a state where the pressing operation (stop operation) with respect to the three stop buttons 140 is permitted (validated), Based on the signal, the supply of the drive pulse (motor drive signal) to the stepping motor of the reel unit 203 is stopped, thereby controlling each of the first to third drums.

  That is, each time the three stop buttons 140 are pressed, the spinning cylinder control means 1300 determines the stopping position of the spinning cylinder corresponding to the pressed button among the first to third cylinders. Thus, control is performed to stop the spinning cylinder at the determined stop position. Specifically, referring to a stop control table (not shown) stored in the storage means (ROM), the first time corresponding to the pressing timing, pressing order, etc. of the three stop buttons (mode of stop operation) A stop position of the cylinder to the third cylinder is determined, and control is performed to stop the first cylinder to the third cylinder at the determined stop position.

  Here, in the stop control table, the positions of the first cylinder to the third cylinder (pressing detection position) at the time when the stop button 140 is operated, and the actual stop positions (or pressing detection of the first cylinder to the third cylinder). Correspondence with the number of sliding frames from the position) is set. Depending on the setting state of the lottery flag, a stop control table for determining the stop positions of the first cylinder to the third cylinder may be prepared.

  In the gaming machine, the reel unit 203 includes an index sensor composed of a photosensor, and the spinning cylinder control means 1300 is based on a reference position signal detected by the index sensor every time the spinning cylinder rotates once. By obtaining the rotation angle (the number of rotation steps of the rotation shaft of the step motor) from the reference position (the frame detected by the index sensor), the current rotation state of the drum can be monitored. That is, the main board 10 can obtain the position of the rotating cylinder when the stop switch 140 is operated by obtaining the rotation angle from the reference position of the rotating cylinder.

  The spinning cylinder control unit 1300 performs so-called pull-in processing and kicking processing as control for stopping the spinning cylinder. The pull-in process is a control for stopping the spinning cylinder so that the symbol corresponding to the combination whose lottery flag is set to the winning state is stopped on a valid winning determination line (so that the winning combination can be won). It is processing. On the other hand, the kicking process means that the symbol corresponding to the combination for which the lottery flag is set to the non-winning state does not stop on a valid winning determination line (so that a non-winning combination cannot be won) Is a control process for stopping the process. That is, in the gaming machine of the present embodiment, the lottery flag setting state, the stop button 140 pressing timing, the pressing order, and the stop position of the spinning cylinder that has already stopped (in the display pattern) in order to realize the pull-in processing and kicking processing. The stop control table is set so that the stop position of each cylinder changes according to the type). In this way, the main board 10 can stop the symbol of the combination for which the lottery flag is set to the winning state in a winning form, while the symbol of the combination for which the lottery flag is set to the non-winning state is in the winning form. Control is performed to stop the first to third cylinders so as not to stop.

  In the gaming machine, the first to third cylinders are set to a control state in which the rotating cylinder corresponding to the pressed stop button is stopped within 190 ms from when the stop button 140 is pressed. Yes. That is, in the stop control table for determining the stop position of each rotating cylinder, the number of frames required from when the stop button 140 is pressed until each cylinder stops is in the range of 0 to 4 frames (predetermined pull-in range). Is set in

  The winning determination means 1400 performs a process of determining whether or not a winning combination has been won based on the stopping modes of the first to third cylinders. Specifically, referring to the winning determination table stored in the storage means (ROM), the symbol combination displayed on the winning determination line when all of the first to third cylinders are stopped. It is determined whether or not this is a predetermined winning combination form.

  The winning determination means 1400 executes a winning process based on the determination result. As a process at the time of winning a prize, for example, when a small role wins, the hopper 81 is driven to perform a medal payout control process, or a credit is increased (a predetermined maximum number is increased to 50, for example, When the replay is won, a replay process is performed. When a big bonus or a regular bonus is won, a game state transition control process for shifting the game state is performed.

  The payout control means 1500 performs payout control processing relating to the payout of medals according to the game result. Specifically, when a small combination wins, the number of medals to be paid out in the game is determined based on a payout predetermined for each combination, and the medals corresponding to the determined number of payouts are determined by the hopper driving unit 80. Then, the hopper 81 is driven to pay out. At this time, a current flows through a motor (not shown) built in the hopper 81.

  When medal credits (internal storage) are permitted, instead of actually paying out medals by the hopper 81, the number of credits stored in a credit storage area (not shown) of the storage means (RAM) (not shown) A credit addition process for adding the number of payouts to the number of credited medals is performed to virtually pay out medals.

  When the replay is won, the replay processing means 1600 performs a replay process (regame process) for setting the same preparatory state as the previous game without requiring insertion of medals owned by the player for the next game. When the replay wins, an automatic insertion process is performed in which a medal with the same specified number of insertions as the previous game is automatically set to the bet state without using the player's own medals (including credit medals). The game machine is set in a state of waiting for a rotation start operation (pressing operation of the start switch 134 by the player) in the next game in a state where the same winning determination line as the previous game is validated. The replay lottery states include a replay no lottery state in which replay is excluded from the internal lottery, a replay low probability state in which the replay winning probability is set to about 1 / 7.3, and a replay winning probability of about 1 / A plurality of lottery states such as a high replay probability state set to 6 can be set. By changing the replay lottery state, the winning probability of the replay in the internal lottery is changed.

  Further, the main board 10 may perform control to shift the gaming state between the normal state, the bonus establishment state, and the bonus state (gaming state transition control function). As the game condition transition condition, one condition may be defined, or a plurality of conditions may be defined. When a plurality of conditions are established, transitioning the gaming state to another gaming state based on the fact that one of the plurality of conditions is satisfied or all of the plurality of conditions are satisfied Can do.

  The normal state is a game state corresponding to the initial state among a plurality of types of game states, and a transition from the normal state to the bonus establishment state is possible. The bonus establishment state is a gaming state that shifts when a big bonus or a regular bonus is won in the internal lottery. In the bonus establishment state, when the big bonus is won in the internal lottery in the normal state, the lottery flag corresponding to the big bonus is maintained in the winning state until the big bonus is won, and the regular bonus is won in the internal lottery in the normal state Until the regular bonus is won, the lottery flag corresponding to the regular bonus is maintained in the winning state. In the bonus state, it is determined whether or not the end condition is satisfied based on the total number of medals paid out by the bonus game, and medals exceeding a predetermined payout limit number are paid out according to the type of bonus won. The bonus state is terminated and the gaming state is returned to the normal state.

  10CG is a command transmitter that transmits a command to be sent to the sub-board 20. This command includes a command related to winning combination information, a command related to information on the number of inserted medals and the number of credits (stored number). Since these are well-known, the description is abbreviate | omitted. Specifically, the command transmission unit 10CG is realized by the CPU executing a program written in advance in a ROM mounted on the main board 10.

  The sub-board 20 generates a command (liquid crystal display device command, drawing command) for displaying a predetermined screen on the liquid crystal display device LCD, for example, in accordance with a command from the main substrate 10.

  The 20CR is a command receiving unit that receives commands received from the main board 10. Specifically, the command receiving unit 20CR is realized by the CPU executing a program written in advance in a ROM mounted on the sub-board 20.

  FIG. 4 is a block diagram of command transmitter 10CG according to the embodiment of the invention.

  Reference numeral 101 denotes a command register that accepts the command to be transmitted. The command register 101 sends the command to the transmission data register 102 immediately after receiving the command. The command register 101 temporarily stores one command.

  The command is a set of data of a predetermined bit, for example, a set of data in units of 8 bits, and is created based on a predetermined command system.

  A transmission data register 102 stores a plurality of commands in the accepted order and outputs them in accordance with the accepted order. The internal structure of the transmission data register 102 will be described later.

  Reference numeral 103 denotes a transmission shift register that receives a command output from the transmission data register 102 and transmits it to the sub-board 20.

  A transmission data register reading unit 104 reads data from the transmission data register 102.

  Note that what is read by the transmission data register reading unit 104 is a plurality of commands, but will be referred to as data here. In general, data is binary digital data, but is expressed as data when a plurality of commands are collectively indicated.

  Reference numeral 105 denotes a power-off save data memory that stores data read by the transmission data register reading unit 104. The power-off saving data memory 105 is a storage device that does not lose stored data even when the power is turned off. For example, it is a non-volatile memory element such as a flash memory, or a CMOS memory that is supplied with current from a battery during a power failure.

  A control unit 106 controls the transmission data register reading unit and the power-off / saving data memory. When the power-off detection unit 107 detects the power-off, the control unit 106 reads the data in the transmission data register 102 by the transmission data register reading unit 104, and reads the data read by the transmission data register reading unit 104 into the power-off save data memory When the power-on detection unit 108 detects power-on, the data is read from the power-off save data memory 105, and the read data is set in the command register as a command to be transmitted.

Reference numeral 107 denotes a power-off detection unit that detects power-off.
Reference numeral 108 denotes a power-on detection unit that detects power-on.

  When the power switch of the gaming machine is turned from on to off, a power-off notice signal is output from a power supply unit (not shown). This signal gives an interrupt to the CPU, for example. The power-off detection unit 107 receives a power-off notice signal. Alternatively, it is a circuit that generates a power-off notice signal. A voltage comparator (comparator) can be used as a circuit for generating a power-off notice signal. A battery with a desired voltage (for example, 18V) is prepared, and a power-off notice signal can be generated by comparing this voltage with the power supply voltage of DC24V. This type of circuit is well known and will not be described in detail. There is a commercially available dedicated IC for monitoring the power supply voltage, and it can be used. Or you may make it generate | occur | produce a power-off notice signal using the switch (or contact) linked with a power switch.

  The power-on detection unit 108 is, for example, a device (a switch or a contact that works in conjunction with the power switch) that detects that the power switch is turned on. Similarly to the power-off notice signal, it is possible to detect power-on using a voltage comparator (comparator). Alternatively, a commercially available dedicated IC for monitoring the power supply voltage may be used.

  Even if the power switch is turned off, the power supply voltage does not drop immediately, and after a while after the power switch is turned off, the power supply voltage becomes zero. The voltage does not immediately become zero because of components such as a capacitor provided in the power supply unit and each circuit. Therefore, the CPU can perform a certain process after receiving the power-off signal until the operation is stopped due to a voltage drop (for example, the power-off process in S2 of FIG. 5).

  FIG. 5 is a schematic process flowchart of the main board 10 of the gaming machine. The figure shows only the processes necessary for explaining the operation of the embodiment of the present invention, and the display of other processes is omitted.

  While the power is on, the gaming machine is performing a predetermined game process, and the main board 10 (especially the transmission shift register 103) is performing a command transmission process (S1). This is a process of sending a command related to winning combination information, a medal inserted number, a command related to information related to the number of credits, etc. Since what kind of command is specifically sent, its protocol, and what kind of processing is performed with this command are known, the explanation thereof is omitted.

  When the hall clerk turns off the gaming machine, the main board 10 performs a power-off process (S2). Note that human operations are indicated by dotted lines in the figure. In the power-off process, an interrupt process is performed in response to a known power-off notice signal, and the contents of the memory such as a winning flag (information of winning combination) at that time are written in a battery-backed memory or a nonvolatile memory. . Even when the power is cut off, the power supply voltage does not decrease during this process, and a predetermined backup process can be executed. The power is turned off after the power-off process (the power supply voltage decreases).

  When the hall clerk turns on the switch of the gaming machine, the power supply voltage rises and the processing is started. First, a state return process is executed by the main board 10 (S3). The state return process is a process for expanding the backed up data in a memory area normally used in the game process and returning to the state immediately before the power is turned off.

  FIG. 6 shows a command set process which is a part of the command transmission process (S1) of FIG. The main board 10 transmits the generated command to the sub board 20 by setting it in the command register 101.

  The steps through which the command is transmitted will be described with reference to FIGS. FIG. 7 shows a case in which the transmission data register 102 is empty, and FIG. 8 shows a case in which some commands are held in the transmission data register 102 but are not full and commands can be written. If it is full, writing is prohibited.

  FIG. 7A shows a state in which the command A is set in the command register 101 by S10 of FIG. If the transmission data register 102 can accept data, in other words, if it is not full (if the FIFO is not full), the command A is immediately sent to the transmission data register 102.

  FIG. 7B is a conceptual diagram showing the operation of the transmission data register 102 that has received the command A. The transmission data register 102 can hold a plurality of commands therein. If the transmission data register 102 is empty, the command A input to its input terminal (left side in the figure) quickly moves to the output terminal (right end in the figure) and can be taken out by the transmission shift register 103. In the state of FIG. 7B, a signal notifying that is sent to the transmission shift register 103.

  In response to the signal, the transmission shift register 103 extracts the command A from the output terminal of the transmission data register 102. The state at this time is shown in FIG. Then, parallel-serial conversion is performed and the serial data is transmitted to the sub-board 20.

  In FIGS. 7A and 7C, since the transmission data register 102 is empty, the command is not lost even if the power is cut off at this time. In FIG. 7A, the command A is backed up by the saving process, and in FIG. 7C, the command transmission can be completed before the power supply voltage completely decreases. On the other hand, in the case of FIG. 7B, since the command is backed up by the process of FIG. 9, it is not lost (in other words, if the process of FIG. 9 is not performed, the case of FIG. 7B) The command of the transmission data register 102 is lost).

  FIG. 8A shows a state in which the command D is set in the command register 101 by S10 of FIG. Commands A to C are already held in the transmission data register 102. If the transmission data register 102 can accept data, the command D is immediately sent to the transmission data register 102.

  FIG. 8B is a conceptual diagram showing the operation of the transmission data register 102 that has received the command D. The command D input to the input end (left side in the figure) quickly moves toward the output end (right end in the figure). At the same time, the command A at the output end is sent to the transmission shift register 103. Therefore, data is held in the transmission data register 102 in the order of commands B, C, and D. This order is the order of writing. The transmission data register 102 can be written and read at the input end and the output end at the same time, and the command D can be written and the command A can be read simultaneously.

  When the power supply is cut off in the state of FIG. 8B, the transmission data register reading unit 104 sends the commands B, C, and D of the transmission data register 102 to the power supply interruption save data memory 105 under the control of the control unit 106. Saved (backed up). As in the case of FIG. 7, the command A is transmitted after the power is turned off, and the command E is backed up.

  Then, in the state restoration process at power-on (S 3), the backup data is read from the power-off save data memory 105 and written to the command register 101 under the control of the control unit 106, so that the saved commands B and C , D return to the transmission data register 102 (commands B, C, D are written to the command register 101 in this order, and are again arranged in this order in the transmission data register 102. The command E is a command B, C, Is written to the command register 101 after D). This state is shown in FIG.

  FIG. 9 is a flowchart of the power-off process.

S20: The transmission data register reading unit 104 reads the contents of the transmission data register 102 under the control of the control unit 106.

S21: The control unit 106 determines whether there is an unsent command.
In the states of FIGS. 7A and 7C, there is no untransmitted command (NO), and in the states of FIGS. 7B and 8B, there is an untransmitted command (YES). If yes, the process of S22 is performed.

S 22: The untransmitted command read by the transmission data register reading unit 104 is stored in the power-off save data memory 105 under the control of the control unit 106.
In the example of FIG. 8B, commands B to D are saved.
Examples of data (command) storage formats in the power-off / save data memory 105 are shown in FIGS. Since it is necessary to store the order of transmission together with the command itself, the commands B, C, and D are stored in the order of transmission according to the order of addresses in the memory as shown in FIG. Alternatively, the command and the transmission order of the command are stored as a set in association with the command.

S23: The control unit 106 clears the transmission data register 102.

  FIG. 10 is a flowchart of the state return process. The state recovery process is performed immediately after the power is turned on.

S30: The control unit 106 reads out an untransmitted command from the power-off / save data memory 105.
In the example of FIG. 8, commands B, C, and D are read.

S31: The untransmitted command read by the control unit 106 is set in the command register 101.
As a result, the saved command is taken into the transmission data register 102 again and returns to the state immediately before the power-off as shown in FIG. The order in which the command register 101 is set must be the order of transmission immediately before the power is turned off. In the example of FIG. 11, commands are set in the command register 101 in the order of memory addresses, and in the example of FIG. The command E is set in the command register 101 after the commands B, C, and D are set by a normal return process (the normal return process is well known and its description is omitted).

  According to the embodiment of the invention, it is possible to perform backup at the time of power-off with respect to a command sent from the main board to the sub-board, and the command will not disappear due to the power-off. Even if the power is cut off during command transmission, an untransmitted command can be transmitted at the next startup, and there is no inconvenience in operations such as effects.

  Next, a more specific configuration will be described with some examples.

  FIG. 13 shows an example in which the transmission data register reading unit 104 is configured with a selector that selects and reads one of the outputs of a plurality of registers. Note that FIG. 13 shows only the portion that performs the read operation, and the display of the portion that performs the write operation is omitted (the same applies to FIGS. 14 and 16).

  R1 to RN are N (N = 2, 3,...) Registers constituting the transmission data register 102. The plurality of registers R1 to RN are arranged in the order of transmission. Each of the plurality of registers R1 to RN stores a command. It becomes full (FIFO full) when all of the registers R1 to RN hold commands, and becomes empty (FIFO empty) when all of them do not hold commands.

  P is a read pointer for designating the output order of commands stored in the plurality of registers R1 to RN.

  SEL 1 is a first selector that selects one of the plurality of registers R 1 to RN according to the output of the read pointer P and outputs a command of the selected register to the transmission shift register 103.

  The pointer is generally an instruction for holding the address of the next record to be accessed or a memory area or register for that purpose. The advance of the pointer means that the contents of the pointer are updated to indicate the next address. The read pointer P holds the information of the last register holding the command together with the position of the first register to be read next. Alternatively, the read pointer P holds information on the number of registers holding a command together with the position of the first register to be read next.

  A configuration different from that shown in FIG. 13 may be employed. For example, a transmission data register can be configured by a ring buffer.

  A ring buffer is a control method for managing and operating a buffer in a ring shape and a buffer realized thereby. The ring buffer reserves a certain area of memory and treats the range as if it is a “ring”. For example, the “ring” is rotated in one direction, and a read pointer (read pointer) and a write pointer (write pointer) are prepared as variables. When writing to the ring buffer, the write pointer advances. The read pointer can be read up to the position indicated by the write pointer. Also, the write pointer cannot pass over the read pointer. Writing begins to write into the buffer from the current write pointer. When writing, the write pointer is advanced by one, but if it matches the read pointer, the buffer is full and cannot be written. Reading is sequentially performed from the read pointer. It ends as if all reading has been completed when it coincides with the write pointer. When both the write pointer and the read pointer reach the end of the buffer, they are returned to the top address. This is why it is processed conceptually as if it were a ring.

  SEL2 is a second selector that selects one of the outputs of the plurality of registers R1 to RN of the transmission data register 102, reads a command from the selected register, and outputs the command. The second selector SEL2 constitutes the transmission data register reading unit 104.

  In FIG. 13, the control unit 106 is configured to be able to read the contents of the read pointer P of the transmission data register 102. That is, the control unit 106 has information on the position of the first register to be read next and information on the last register holding the command (or the position of the first register to be read next and the number of registers holding the command). Information) can be read out.

  The control unit 106 performs the following processing.

(1) When power-off detection unit 107 detects power-off, the data in transmission data register 102 is read. At this time, the command output order is obtained by referring to the read pointer P, and the second selector SEL2 selects one of the plurality of registers R1 to RN in accordance with this, and the command of the selected register is stored in the power-off save data memory. Write to 105 in order. According to this process, the save data is written as shown in FIG.

(2) When power-on is detected by the power-on detection unit 108, commands are read from the power-off save data memory 105 in the order of writing and set in the command register 101.

  Note that the following processing may be performed instead of the above (1) and (2).

(1 ') When power-off detection unit 107 detects power-off, data in transmission data register 102 is read. At this time, the second selector selects and reads any of the plurality of registers R1 to RN, reads the contents of the read pointer P, determines the order of the read commands based on the read pointer P, and reads the read commands and the order of the commands. Are written in the power-off / save data memory 105. According to this process, the save data is written as shown in FIG.

(2 ′) When the power-on detection unit 108 detects power-on, the power-off save data memory 105 is checked in order, and the command is read and set in the command register 101 according to the order.

  FIG. 14 shows an example in which the transmission data register reading unit 104 is configured by latches (saving registers) L1 to LN that read the outputs of the plurality of registers R1 to RN, respectively. In FIG. 14, the same reference numerals are given to the same parts as those in FIG. 13, and the description thereof is omitted.

  L1 to LN are save registers (latches) provided in the same number corresponding to the plurality of registers R1 to RN of the transmission data register 102, respectively. The latches L1 to LN constitute a data register reading unit 104.

  BAT is a backup power source for allowing the latches L1 to LN of the data register reading unit 104 to hold data even when the power is cut off. Note that when the latches L1 to LN are configured by a nonvolatile memory, a backup power source is not necessary.

  Also in FIG. 14, the control unit 106 is configured to be able to read the contents of the read pointer P of the transmission data register 102.

  The control unit 106 performs the following processing.

(1) When the power-off detection unit 107 detects a power-off, the data (commands) of the registers R1 to RN of the transmission data register 102 are transferred to the latches L1 to LN. In the example of FIG. 14, since the input ends of the latches L1 to LN are connected to the output ends of the registers R1 to RN, data transfer is performed all at once according to a fetch instruction from the control unit 106. The fetch command is generated in the power-off process. At the same time, the control unit 106 stores the contents of the read pointer P in the power-off / save data memory 105. That is, the control unit 106 has information on the position of the first register to be read next and information on the last register holding the command (or the position of the first register to be read next and the number of registers holding the command). Is stored in the power-off / save data memory 105. In the example of FIG. 14, the command itself is not stored in the power-off / save data memory 105.

(2) When the power-on detection unit 108 detects power-on, the contents of the read pointer stored in the power-off save data memory 105 are read, and the order of saved commands is determined based on the read pointer, and a plurality of commands are determined according to the order. The command is read from the save register and set in the command register. For example, when the commands B, C, and D are held in the registers R1, R2, and R3, the control unit 106 reads out the commands in the order of the latches L1, L2, and L3 and writes them in the command register 101.

  FIG. 15 shows a block diagram of a command transmitter different from FIG. 4 that are the same as those in FIG.

  Reference numeral 109 denotes a transmission data register writing unit that sets data in the power-off / saving data memory 105 and information on the order of transmission thereof in the transmission data register 102.

  In FIG. 15, data is set directly in the transmission data register 102 instead of the command register 101. Since this data includes a plurality of commands, it is necessary to set information on the order of transmission. The information of this order is stored together with the data from the transmission data register 102 in the power-off save data memory 105 at the time of saving.

  FIG. 16 is a block diagram showing a specific configuration of FIG. The same reference numerals are given to the same corresponding parts in FIG. 14, and the description thereof is omitted.

  In FIG. 15 using the configuration of FIG. 16, transmission data reading unit 104 and transmission data writing unit 109 are configured by common latches L1 to LN. In other words, the latches L1 to LN function as both the transmission data reading unit 104 and the transmission data writing unit 109. The input ends of the latches L1 to LN are connected to the output ends of the registers R1 to RN, and the input ends of the registers R1 to RN are connected to the output ends of the latches L1 to LN.

  The control unit 106 performs the following processing.

(1) When the power-off detection unit 107 detects a power-off, the data (commands) of the registers R1 to RN of the transmission data register 102 are transferred to the latches L1 to LN. In the example of FIG. 16, since the input ends of the latches L1 to LN are connected to the output ends of the registers R1 to RN, data transfer is performed all at once according to a fetch instruction from the control unit 106. The fetch command is generated in the power-off process. At the same time, the control unit 106 stores the contents of the read pointer P in the power-off / save data memory 105. In the example of FIG. 16, the command itself is not stored in the power-off / save data memory 105.

(2) When power-on detection unit 108 detects power-on,
Data (commands) of the latches L1 to LN of the transmission data register reading unit 104 / transmission data register writing unit 105 are transferred to the registers R1 to RN of the transmission data register 102. In the example of FIG. 16, since the input ends of the registers R1 to RN are connected to the output ends of the latches L1 to LN, data transfer is performed all at once in accordance with a fetch command from the control unit 106 to the transmission data register 102. The fetch command is generated in the state return process.

  In addition to this, the control unit 106 reads the contents of the read pointer stored in the power-off save data memory 105 and transfers it to the read pointer P of the transmission data register 102.

  With the above processing, the plurality of commands and their transmission order have returned to the state immediately before the power was turned off.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
