FIELD OF THE INVENTION  
      The present invention relates to a game machine such as an arcade game placed in an arcade and the like.  
     RELATED ART  
      Conventionally, multi-player-type game machines for commercial use, wherein numerous players participate, commonly referred to as multi-player game machines, are known. In recent years, there has been a horse-racing game machine as such a multi-player game machine. A multi-player game machine such as this includes, for example, a main game machine body to which a large main display part is provided and a plurality of terminal devices to which sub-display parts which are attached to the main game machine body are provided (Patent Reference 1).  
      These plural terminal devices are provided with seats, respectively, which seat the players, and face the main display part. In this terminal device, each player sits in the seat and performs various operations while watching the sub-display part mounted on the seat.  
      In this multi-player game machine, the race horses and the odds are shown in the main display part and the sub-display part. Each player selects an arbitrary race horse among the race horses shown and bets medals. Then, racing is performed by these race horses in the main display part and medals are paid out to each player according to the results, based on odds set beforehand.  
      In a multi-player game machine such as this, each terminal device is connected to the main game machine body by communication cables, respectively. By performing bidirectional communication via these communication cables, information necessary for the game is exchanged (refer to Patent Reference 1).  
      Incidentally, in a communication game machine, which is a type of a multi-player game machine such as this, seats which are higher in quality than conventional seats are used such that players do not become tired, even when playing for long periods of time. In addition, in a communication game in which the main content of the game is to bet medals on a horse-racing game shown on the main screen and pay out medals based on the odds set by the gaming device, presenting a high-class casino-like atmosphere by giving the seats an expensive appearance is proposed.

      However, the following problems exist in the foregoing multi-player game machine.  
      When seeking further improvement in functionality and a sense of luxury in a terminal device used in a multi-player game such as this, for example, a sub-display part which can change positions according to the position of the player can be provided for each terminal device. Here, the sub-display part can preferably be moved to a position enabling viewing by the player when the game begins and can be stored into the seat such that the player can sit down smoothly.  
      In addition, it is preferable that, in the foregoing, the sub-display part automatically move from a state of being stored within the seat to a state enabling viewing by the player, based on predetermined conditions such as the player being seated, because the sense of luxury is further enhanced.  
      In addition, it is preferable that, in the foregoing, the sub-display part which has been moved to a state enabling viewing by the player be held and a mechanism for preventing vibrations and swaying of the sub-display part be provided, because usability is further improved.

      The seating detector  525  is placed under the seat surface of the seating part  52  and detects that the player is seated. Then, if the seating detector  525  detects that the player is seated, a predetermined control signal is transmitted from the main control device  80  to the sub-control device and the sub-control device  90  controls the driving mechanisms which drive the connection device and the holding device.  
      A sub-monitor storage part  62  is formed in the side unit  60  and a sub-display part  61  is stored within this sub-monitor storage part  62 . A storage part cover  66  is placed to enable opening and closing in the opening part in the upper part of the sub-monitor storage part  62  and, for example, is configured such that the sub-monitor storage part  62  can be opened when the medal insertion detector  735  detects the insertion of a medal, which is a game medium. In other words, the sub-monitor is released from a state prohibiting outward movement from the sub-monitor storage part  62 , by meeting predetermined conditions. Here, other than placing the sub-monitor  613  in a movement prohibited state by the storage part cover  66 , as such, for example, the sub-monitor  613  can be placed in a movement prohibited state by locking the connection device  600 . These movement prohibition mechanisms are controlled based on the status of the game run by the game program, as described hereafter. For example, the movement prohibition mechanisms are controlled to release the movement prohibition state when the game status is a state enabling play.  
      As shown in  FIG. 2  to  FIG. 5 , the sub-display part  61  includes a second support arm  611  which is supported by the side unit  60 , a first support arm  612  which is attached to the tip of the second support arm  611 , and a flat, rectangular sub-monitor  613  which is attached to the tip of the first support arm  612 .  
      The second support arm  611  can be expanded and contracted freely in the direction vertical to the side unit  60 . The first support arm can extend and retract freely and can be fixed to an arbitrary angle to the axis direction of the second support arm  611 . The sub-monitor  613  can be fixed to an arbitrary angle to the axis direction of the first support arm  612 .  
      The sub-display part  61  is described in further detail by  FIG. 13 . The display part  61  includes: a flat, rectangular sub-monitor  613 ; a first axis part  617  for supporting the sub-monitor  613  to enable rotation; a first support arm  612 , of which one end is connected to the first axis part  617 ; a second axis part  616  which is placed on the other end of the first support arm  612  and supports the first support arm  612  to enable turning; and a second support arm of which one end is connected to the second axis part  616  and the other end is connected to the side unit  60  of the terminal device  30 .  
      Furthermore, the sub-display part  61  includes: a rotation driving part  617 A which is connected to the sub-monitor  613  and rotates an image display part  613 A to face the player-side; a turning driving part  616 A which is connected to the first support arm  612  and turns the first support arm  612 ; and an extending and retracting driving part  615 A which is placed in the second support arm  612  and extends and retracts the second support arm  611 .  
      In addition, the sub-display part  61  includes: a first load detection part  617 B, placed in the vicinity of the rotation driving part  617 A, for detecting the load applied to the rotation driving part  617 A; a second load detection part  616 B, placed in the vicinity of the turning driving part  616 A, for detecting the load applied on the turning driving part  616 A; and a third load detection part  615 B, placed in the vicinity of the extending and retracting driving part  615 A, for detecting the load applied to the extending and retracting driving part  615 A. If a load which is greater than the predetermined load is applied to each driving part, each detector transmits a signal notifying the sub-control device  90  not shown that a load greater than the predetermined load has been applied. The sub-control part which received this signal can control respective constituent parts according to the size of the load and the circumstances wherein the load is applied.  
      For example, if the pressing force to the touch-panel part  613 B, placed in the sub-monitor  613 , is large and a load which is greater than the predetermined load (for example, a first load) is detected by the first load detection part  617 B or the second detection part  616 B, a predetermined sound, such as the sound of air being released, is generated and the player is warned that they are pressing the sub-monitor  613  too hard. This is so as not to encourage excessive pressing of the sub-monitor  613  by the player. This predetermined sound, such as the sound of air being released, can be a sound which is physically generated when opening the first safety valve  617   c  or the second safety valve  616   c , described hereafter, or can be a simulated pseudo-sound. Furthermore, a so-called warning sound can be released from the speaker  75 . This warning regarding excessive pressing of the sub-monitor  613  by the generation of this predetermined sound is performed in the stage before the sub-monitor  613  is cleared when excessive pressing force is applied to the touch-panel part  613 B, described hereafter. In order that a situation interfering with the progress of the game, meaning the movement to safety of the sub-monitor  613 , does not occur, this warning is effective in notifying the player that it is a stage prior thereto. In addition, if the sub-monitor  613  continues to be pressed hard, even after warning by the generation of this predetermined sound is received, the sub-monitor  613  and the connection device  600  are moved to safety, described hereafter, in order to prevent damage thereto.  
      In addition, for example, if the pressing force applied to the touch-panel part  613 B, placed in the sub-monitor  613 , is large and the first lead detection part  617 B or the second load detection part  616 B detects a load which is greater than the predetermined load (for example, a second load), as above, the sub-monitor  613  and the like are controlled by the predetermined pressing force reduction mechanism to be cleared in a direction heading away from the player. A detailed example is given hereafter.  
      In addition, for example, if the first load detection part  617 B or the like detects a load which is greater than a predetermined load (for example, a third load) while the sub-monitor  613  is being moved by the connection device  600 , the first safety valve  617   c  or the like are opened. In this way, damage to the sub-monitor  613  and the connection device  600  is prevented. In addition, if the player&#39;s hand is caught between the sub-monitor  613  and the sub-monitor storage part  62  or the like when the sub-monitor  613  is moved to be stored within the sub-monitor storage part  62 , a damper, such as an air damper which is not shown which is placed in the connection device, cooperates to prevent injuries to the player. A detailed example is given hereafter.  
      The sub-monitor  613  includes an image display part  613 A, which is placed in one wide surface thereof, a small CCD camera  614 , and a position sensor  604 . This image display part  613 A is composed of a liquid crystal display, a plasma display, an organic EL (ElectroLuminescent) display or the like.  
      In addition, the image display part  613 A includes a touch-panel part  613 B. By directly touching the tough-panel part  613 B, the player can operate the terminal device or give predetermined instructions during a game. This touch-panel part  613 B is formed by placing a transparent touch-panel sheet on the front surface of the image display part  613 A. Then, if the touch-panel  613 B is formed as such, the game images and the like which are shown in the image display part  613 A on the back surface side can be viewed through the touch-panel part  613 B. In other words, the player can perform predetermined input operations with the touch-panel part  613   b  while viewing the game images shown in the image display part  613 A.  
      Here, although the player performs input operations by pressing the touch-panel  613 B, the sub-monitor  613  and the connection device  600  is damaged if the pressing force is too strong because the sub-monitor is held in a cantilevered-state by the connection device  600 . In order to reduce the influence of such pressing force, a predetermined pressing force reduction mechanism is provided, a detailed example thereof given hereafter.  
      As shown in  FIG. 14 , the sub-monitor  613  is supported to enable turning by a sub-monitor turning axis  660 , provided in the end part of the connection device  600 , via the turn urging part  661 . The turn urging part  661  is rotation-energized by a predetermined urging force F 4 , in the direction opposite of the direction in which the sub-monitor  613  turns, by the pressing operation by the player. During a normal state, the tuning of the sub-monitor  613  by the turn urging part  661  to the player-side is regulated by an un-illustrated locking part not shown. In addition, if load F 3  in the turning direction, generated in the sub-monitor turning axis  660  by the pressing force F applied to the sub-monitor by the player, is greater than the urging force F 4  in the turning direction, provided by the turn urging part  661 , the sub-monitor  613  is turned and cleared to the direction heading away from the player (direction of F 3 ), and damage to the sub-monitor  613  and the connection device  600  and the like due to the pressing force F is prevented. Here, the turn urging part  661  can be configured as a spring formed to be wound around the turning axis or a lock which is released when a load greater than a predetermined load is applied. In addition, the turning driving part  616 A, the rotation driving part  617 A, and the like, which are connection device driving devices, can be controlled and the sub-monitor can be turned and cleared, according to the load detected by the first load detection part  617 B and the second load detection part  616 B.  
      As shown in  FIG. 15 , the connection device connected to the sub-monitor  613  is connected to the bottom part of the sub-monitor storage part  62  to enable sliding by the connection rod sliding mechanism  665 . A sliding part component  667  which is provided on one end of the connection rod in the connection device  600  is placed on a sliding groove  666 , formed on the bottom surface of the sub-monitor storage part  62 , to enable sliding. The urging part  663  which is placed such as to expose one surface thereof from the side surface of the sub-monitor storage part  62  includes a contact part  664  which is in contact with the connection rod and urged the connection rod with urging force F 2  on the player side  668 . The movement of the connection rod to the player-side due to the urging part  663  is regulated by the locking part  668  which is provided in the player-side. In addition, if the load F 1  which is generated in the connection rod by the pressing force F applied to the sub-monitor  613  by the player is greater than the urging force F 1  provided by the urging part  663 , the connection rod is slid and cleared in the direction away from the player (direction of load F 1 ) and damage to the sub-monitor  613 , the connection device  600  and the like due to the pressing force F can be prevented. Here, the urging part can be configured as a spring with a predetermined shape or a lock which is released when a load greater than a predetermined load is applied.  
      Here, if the pressing force reduction mechanism is configured such that the sub-monitor  613 , which has been cleared to the pressing direction, is returned to its original position, for example, because it is not necessary to halt the game or the like due to moving the sub-monitor  613  to safety, when the pressing force reduction mechanism is the urging part  663  or the turn urging part  661 , the player can play the game continuously. Through this, damage to the sub-monitor can be prevented and the player can attain a sense of satisfaction, as well.  
      A CCD camera  614  is placed on the same surface of the sub-monitor  613  as the surface to which the image display part  613 A is placed. This CCD camera  614  is used mainly when creating an avatar in the game field. In addition, the image taken by the CCD camera  614  can be shown constantly in the image display part  613 A of the sub-monitor  613 . Through this, the player can see his own expression during the game, thus increasing enjoyment. In this case, the taken image can be shown in the entire image display part  613 A of the sub-monitor  613  or can be shown in one part thereof. These image displays can be switched by operating the input operation part  72  (described hereafter). Furthermore, the sub-control device  90  analyzes the image taken by the CCD camera  614  and verifies whether the sub-monitor  613  is placed in a position enabling viewing by the player, accordingly.  
      A position sensor  604  is placed on the same surface in the sub-monitor  613  as the surface to which the image display part  613 A is placed. The position sensor  604  detects the position of the player and detects whether the player is in an appropriate position. In other words, the position sensor  604  detects whether the sub-monitor  613  is placed in a position enabling viewing by the player. In addition, if the sub-monitor  613  is in a position enabling viewing by the player, a viewing possible signal which notifies the sub-control device  90  which is not shown that the sub-monitor  613  is in a position enabling viewed by the player is output. The sub-control device  90  which received this viewing possible signal transmits a signal notifying the main control device  80  that this viewing possible signal had been received. The main control device  80 , which receives this signal, transmits an adjustment signal for instructing control that the sub-monitor  613  is placed in a position enabling viewing to the sub-control signal. Furthermore, the sub-control device  90  which receives this adjustment signal controls the connection device driving mechanism for driving the connection device and moves the sub-monitor  613  to a position enabling viewing.  
      When the player is not seated, the sub-monitor  613  is stored to the sub-monitor storage part  62  which is formed in the side unit  60  such that the upper part is open and extends in a vertical direction. When the sub-monitor  613  is in a state of being stored within the sub-monitor storage part  62 , a storage part cover  66  covers the opening part in the upper part and the sub-monitor cannot be moved outward. In addition, for example, if the predetermined conditions regarding when the medal insertion detector  735  detects the insertion of a predetermined number of medals, which are the game media, when a game start input is received from the input operation part  72 , or when the seating detector  525  detects that the player is seated, are met, the storage part cover  66  can be opened manually or automatically by the CPU  91 , described hereafter, and the sub-monitor is moved outward. Furthermore, the sub-monitor  613  is pulled out from the sub-monitor storage part  62 , manually or automatically. If the sub-monitor  613  is automatically pulled out of the sub-monitor storage part  62 , for example, it is movement-controlled to a position enabling viewing by the player, with the foregoing predetermined conditions and the like as a trigger. An example of this operation is described hereafter.  
      Reception of an input instructing the moving of the sub-monitor  613  by the input operation part  72  and detection of the player being seated by the seating detector  525 , for example, can be given as triggers by which the sub-monitor  613  is automatically moved to a position enabling viewing, as is given as the triggers for releasing the movement prohibited state of the sub-monitor  613 . After the sub-monitor  613  is released from the movement prohibited state and can be moved, the main control device  80  transmits a movement signal instructing for the sub-monitor  613  to be moved and controlled into a state enabling play to the sub-control device  90 , as a trigger for predetermined operations and the like, and the sub-control device  90  which receives this movement signal controls the extending and retracting driving part  615 A which is a connection device driving device, the turning driving part  616 A and the rotation driving part  617 A and places the sub-monitor  613  in a state enabling play by movement-controlling to a predetermined position from a state of being stored within the sub-monitor storage part  62 . Detailed operations are described in  FIG. 9  to  FIG. 12 .  
      The sub-display part  61  in  FIG. 9  is in a state of being stored within the sub-monitor storage part  62 . In this state, the storage cover  66  is closed and the sub-monitor  613  cannot be moved outside. The connection device  600  which is connected to the sub-monitor  613  is contracted, and the sub-monitor is stored in a state wherein the surface to which the connection device  600  is connected is the bottom surface and the image display part  613 A (refer to  FIG. 10 ) faces the side of the player not shown who is seated in the seat. After the storage part cover  66  is opened by a predetermined trigger, the sub-display part  61  in a stored state in this  FIG. 9  pulls the sub-monitor  613  outward from the sub-monitor storage part by expanding the second support arm  611  by the extending and retracting driving part  615 A, as shown in  FIG. 10 . Next, the sub-display part  61 , of which the sub-monitor  613  is pulled outward from the sub-monitor storage part  62 , is placed in a state shown in  FIG. 11 , wherein the first support arm  612  is turned by the turning driving part  616 A, and the sub-monitor  613  is moved to the vicinity of the player not shown and is placed such that the image display part  613 A is facing down. Then, the sub-display part  61 , which is moved to the vicinity of the player not shown and is placed such that the image display part  613 A is facing down, is placed in a state shown in FIG.  12 , wherein the sub-monitor  613  is rotated by the rotation driving part  617 A and is placed such that the image display part  613 A faces the player not shown.  
      The position sensor  604  in  FIG. 12  detects the position of the player and detects whether the sub-monitor  613  is placed in a state enabling viewing by the player. Then, if the sub-monitor  613  is not placed in a state enabling viewing by the player, the main control device  80  transmits an adjustment signal instructing for the sub-monitor  613  to be movement-controlled into a state enabling viewing by the player to the sub-control device  90 . Upon receiving this adjustment signal, the sub-control device  90  drive-controls the turning driving part  616 A and the rotation driving part  617 A, which are connection device driving mechanisms and places the sub-monitor  613  in a state enabling viewing by the player.  
      Here, as a prerequisite for the trigger which starts the driving of the sub-display part  61 , detection of the insertion of a medal, which is a game medium, by the medal insertion detector  735  can be given. In other words, the sub-monitor  613  cannot be pulled out of the sub-monitor storage part  62  by merely entering an instruction for the movement of the sub-monitor  613  or by the player sitting down, but rather, the sub-control device is configured to enter a reception enabled state, in which a movement signal from the main control device  80  can be received, only when a medal, which is a game medium, is inserted into a medal insertion part  734 , and this is detected by the medal insertion detector  735 . In this case, for example, when the medal insertion detector  735  detects the insertion of a medal, which is a game medium, the storage part cover  66  can be opened and the sub-monitor enters a state enabling movement. Then, when the seating detector  525  detects that the player is seated, the sub-monitor  613  can be pulled out automatically into a position enabling viewing by the player.  
      Although, as stated above, the sub-monitor  613  is moved automatically from a state of being stored within the sub-monitor storage part  62  into a state enabling play which is a state enabling view by the player, configurations can further be made such that this sub-monitor  613 , which is in a state enabling play, is stored automatically within the sub-monitor storage part  62 . For example, when an input instructing game termination is received by the input operation part  72  or when the seating detector  52  detects that the player has left the seating part  52 , the main control device  80  transmits a storage signal instructing for the sub-monitor  613  to be controlled to be stored within the sub-monitor control device  80  to the sub-control part  90 . Then, after receiving this storage signal, the sub-control device  90  controls the extending and retracting driving part  615 A, the turning driving part  616 A, and the rotation driving part  617 A, which are connection device driving mechanisms and the sub-monitor  613  can be stored automatically within the sub-monitor storage part  62 . Here, the extending and retracting driving part  615 A, the turning driving part  616 A, and the rotation driving part  617 A, which are connection device driving mechanisms, can be directly controlled by transmitting predetermined control signals from the main control device  80  thereto.  
      Although an instance wherein the sub-monitor  613  is placed automatically in a state enabling viewing by the player is described above, the same operations can be performed manually. For example, the player, while seated in the main seat body  50 , slides the sub-monitor  613  upward from the sub-monitor storage part  62 , as shown in  FIG. 10 , from the sub-display part  61  in a stored state in  FIG. 9 , and extends the second support arm  611 . Then, as shown in  FIG. 11 , the sub-monitor  613  is placed in the vicinity of the player by pulling the sub-monitor  613  to the player-side. Next, as shown in  FIG. 12 , the sub-monitor  61  is turned, the relative angles of the first support arm  612  and the sub-monitor  613  are adjusted, and the image display part  613 A can be placed in a position enabling viewing in the player&#39;s line of vision. Even when the sub-monitor  613  is moved manually into a position enabling viewing by the player as such, the sub-monitor  613  becomes mobile when, for example, the game status changes due to a predetermined trigger, such as the medal insertion detector  735  detecting the insertion of a predetermined number of medals, which is a game medium, and the storage part cover is opened according to this game status.  
      In  FIG. 16  and  FIG. 17 , the sub-monitor  613  which is placed in a state enabling viewing by the player, shown in  FIG. 12 , is the sub-display part  61  which is held by the holding device  400 . The holding device  400  in  FIG. 16  includes a holding rod  411 , a holding device storage part  40  for storing the holding rod  411 , and an engaging part  413  which is placed at one end of the holding rod  411 . The holding rod  411  is an accordion-shaped component which can be extended and retracted and is connected on one end to the side of the terminal device  30  which is opposite of the side to which the connection device  600  is fixed, to enable turning. The engaging part  413  is engaged to the engaged part  414  which is formed on a side surface of the sub-monitor  613 , on the surface opposing the surface to which the connection device  600  is connected. Through this, the holding device  400  holds the sub-monitor  613 , which is supported in a cantilevered-state by the connection device  600 , in a position enabling viewing by the player.  
      The holding device further includes: a holding device extending and retracting driving device  415 , which is placed in the holding rod  411 , for extending and retracting the holding rod  411 ; and a holding device turning driving device  416 , which is connected to the holding rod  411 , for turning this holding rod  411 . The holding device extending and retracting driving device  415  extends the holding rod  411  which is stored in the holding device storage part  40  and the holding device turning driving device  416  turns the holding rod  411  such that the engaging part  413  engages with the engaged part  414 .  
      By the foregoing configuration, the holding device  400  can engage with the sub-monitor  613  which is held in a cantilevered-state by the connection device  600  in a state enabling play, automatically, from a state of being stored within the holding device storage part  40  such that the player can be seated separately from the sub-monitor  613  during a normal state, and move the sub-monitor  613  such as to hold this state by the holding device extending and retracting driving device  415  and the holding device turning driving device  416 , which are holding device driving mechanisms for driving the holding device  400 . In addition, the holding device  400  can automatically separate from a state of being engaged with the sub-monitor  613  and be stored within the holding device storage part  40 . Here, the holding device extending and retracting driving device  415  and the holding device turning driving device  416 , which are holding device driving mechanisms, can be controlled directly by transmitting predetermined control signals from the main control device  80 .  
      Here, as a trigger for driving the holding device  400 , the driving of the holding device extending and retracting driving device  415  and the holding device turning driving device  416  can begin when, for example, the position sensor  604  or the like detects that the sub-monitor  613  is placed in a state enabling viewing by the player. For example, if the position sensor  604  detects that the sub-monitor is in a state enabling play, the main control device  80  transmits an engagement signal which instructs the holding device  400  to engage-control and hold the sub-monitor  613  to the sub-control device  90 . Upon receiving this engagement signal, the sub-control device  90  can control the holding device extending and retracting driving device  415  and the holding device turning driving device  416 , which are holding device driving mechanisms, and the engaging part  413  can be engaged with the engaged part  414  which is provided in the sub-monitor  613 .  
      In addition, when an input instructing game termination is received by the input operation part  72 , the main control device  80  transmits a separation signal for instructing the engaging part  413  to be separation-controlled from the engaged part  414  to the sub-control device  90 . Upon receiving this separation signal, the sub-control device  90  can control the holding device extending and retracting driving device  415  and the holding device turning driving device  416 , which are holding device driving mechanisms, and the engaging part  413  can be separated from the engaged part automatically. Here, the holding device extending and retracting driving device  415  and the holding device turning driving device  416  can be controlled directly by transmitting predetermined control signals from the main control device  80 .  
      The holding device  400  in  FIG. 17  includes a holding rod  411 , a holding device storage part  40  for storing the holding rod  411 , and an engaging part  413  which is placed in one end of the holding rod  411 . The holding rod  411  is an accordion-shaped component which can be extended and retracted and is connected on one end to a table  71 , described hereafter, to enable turning. The engagement part  413  is engaged with an engaged part  414  which is formed on the surface on the sub-monitor  613  opposite of the surface on which the image display part  613 A is placed. In this way, the holding rod  411  can hold the sub-monitor  613  in a position enabling viewing by the player and hold the sub-monitor  613  so as to resist the force of pressing on the touch-panel part  613 B which is placed in the image display part  613 A.  
      The driving device for driving the connection device  600  is explained using the block diagram in  FIG. 18 . The rotation driving device  617 C which includes the rotation driving part  617 A is a driving device utilizing air-pressure. The rotation driving device  617 C includes an air-pressure generation part  617   a , a first control part  617   b , a first safety valve  617   c , a first operation part  617   d , and a first ventilation pipe  617   e . Air pressure generated by the air-pressure generation part  617   a  ( 616   a  and  615   a ) which also act as the air-pressure generation part for other driving devices is controlled in the first control part  617   b  at a predetermined pressure. This controlled air-pressure is carried to the first operation part  617   d  thought the first ventilation pipe  617   e . The first operation part  617   d  converts the air-pressure carried by the first ventilation pipe  617   e  into rotation-direction motion and rotation-drives the sub-monitor  613 . The first load detection part  617 B detects the load applied to the rotation driving part  617 A, and if this load is greater than the predetermined load, a signal notifying that a load exceeding the predetermine load is being applied to the rotation driving part  617 A is output to the sub-control device  90 . Upon receiving this signal, the sub-control device  90  transmits a signal for opening the first safety valve  617   c , placed in the first ventilation pipe  617   e , to the first safety valve  617   c . Upon receiving this signal, the first safety valve  617  is opened and reduces the air-pressure carried to the operation part.  
      The turning driving device  616 C which configures the turning device part  616 A includes an air-pressure generation part  616   a , a second control part  616   b , a second safety valve  616   c , a second operation part  616   d , and a second ventilation pipe  616   e . The second operation part  616   d  converts the air-pressure to a rotation-direction motion and turn-drives the first support arm  612 . The extending and retracting device  615 C which configures the extending and retracting driving part  615 A includes an air-pressure generation part  615   a , a third control part  615   b , a third safety valve  615   c , a third operation part  615   d , and a third ventilation pipe  615   e . The third operation part  615   d  converts the air-pressure to an extending and retracting-direction motion and extending and retracting-drives the second support arm  611 . The turning driving device  616 C and extending and retracting device  615 C are controlled in the same way as the foregoing rotation driving device  617 C.  
      By controlling in this way, the air-pressure carries by the driving devices  615 C,  616 C, and  617 C are reduced automatically, even when, for example, the player&#39;s body is caught between the sub-monitor  613  and the terminal device  30  or the like, and thus, injuries to the player can be prevented. As injury prevention, for example, a damper which is not shown, such as an air-damper, may be placed in the vicinity of the extending and retracting driving part  615 A connection device. For example, if an air-damper is placed in the vicinity of the extending and retracting driving part  615 A, the storage speed of the sub-monitor  613  to the sub-monitor storage part  62  can be prevented from becoming excessively fast and injuries such as the player&#39;s hand getting caught by the sub-monitor  613  while storing can be prevented. In addition, if the sub-monitor  613  is configured to release the sound of air being released when storing the sub-monitor  613 , the player will acknowledge that the sub-monitor  613  is being stored and this will effectively prevent injuries to the player.  
      In addition, by controlling as such, excessive loads being applied to the extending and retracting driving part  615 A, turning driving part  616 A, and rotation driving part  617 A can be prevented and malfunctions and the like of the extending and retracting driving part  615 A, turning driving part  616 A, and rotation driving part  617 A can be prevented. Here, as in the foregoing, by controlling respective driving parts according to the size of the load and the circumstances under which the load is applied, warning of excessive pressing of the sub-monitor  613  by the foregoing predetermined sound and reduction of the pressing force can be achieved. For example, if the touch-panel is press-operated and the load applied to any one of the driving parts exceeds the predetermined lead, the sub-monitor  613  can be moved to safety by opening any one of the safety valves. Here, if configurations are made such that the sound of air being released is generated when any one of the safety valves are opened, the foregoing warning through sound and moving of the sub-monitor  613  to safety to reduce the pressing force can be performed simultaneously.  
      A sub-control device  90  which is connected by wireless LAN to the main control device  80  and a plurality of board storage slots  97  which configure this sub-control device  90  are provided within the side unit  60 .

A holder, not shown, for attaching a medal storage container  733  is provided in the medal reception part  732 . For example, predetermined odds are stipulated to the participants of a certain event (win/loss of horse-racing, combat, etc.), much like a book-maker, and the player places a bet on a desired object. Then, medals are paid out according to the odds or the like, based on the win/loss results. The prize resulting from this book-maker is not limited to medals and can be items within the game environment.  
       FIG. 19  is a block diagram showing the entire configuration of the game machine  1 .  
      In this game machine  1 , the main control device  80  of the main game machine body  20  had a wireless communication part  83  and the sub-control device  90  of the terminal device  30  has a wireless communication part  93 . These wireless communication parts  83  and  93  can be interconnected by a wireless LAN, and thus, the transfer of voice data and character data can be performed between the main control device  80  and the sub-control device  90 .  
      Configuration of the Main Control Device  
       FIG. 20  is a block diagram showing the configuration of the main control device  80 .  
      The main control device  80  has a CPU  81  which is the main control part, a memory  78 , a wireless communication part  83  and a database  84  which is a memory part, which are connected to a data bus BUS.  
      The wireless communication part  83  includes a transceiving circuit part (RF)  85  for transmitting and receiving signals with the sub-control device  90 , and a base band processing part  86  for converting RF (Radio Frequency) signals received by the transceiving circuit part  85  into base band signals and also converting base band signals to be transmitted into RF signals.  
      The database  84  is a circuit board which includes a memory part to which a game program is stored or a storage medium (for example, a hard disk or ROM cassette) to which the game program is stored.  
      Specifically, a slot to which these circuit boards and storage mediums can be attached and removed is provided in the main control device  80 . By attaching and removing these circuit boards and storage mediums from the slot, the game program stored to the database  84  can be replaced, accordingly, and other game programs can be executed. Replacing the game program is not limited to that via hardware, as such, and software can be replaced directly by downloading via a communication circuit.  
      CPU  81  transmits and receives data with the sub-control devices  90  of each terminal device  30 , via the wireless communication part  83 , by the procedure below.  
      Specifically, the CPU  81  converts data into packet data when transmitting data to the sub-control device  90  of the terminal device  30 . At this time, the IP address of the identified terminal device  30 , which is the destination, is added to the package data.  
      In addition, the CPU  81  identifies the terminal device which is the transmission source of the data when receiving data from the sub-control device  90  of the terminal device  30 , based on the IP address added to the packed data.  
      The foregoing CPU  81  executes the game program and performs various processing as a result. In other words, the CPU  81  reads the game program stored in database  84  to the memory  82  and runs the game according to this game program.  
      Specifically, the CPU  81  receives data including game input data, described hereafter, respectively, from the plurality of terminal devices  30 , and generates a single game data according to the game program, based on these data. Then, the CPU  81  generates image data which is shared with all of the terminal devices  30 , based on the generated single game data, and outputs this data to the main display device  22 .  
      Here, the single game data includes a plurality of operation character data which can be moved within the single game field generated according to the game program, based on the respective game input data of the plurality of terminal devices  30 , and the positional data of this plurality of operation characters.  
      If a plurality of game input data is received from a plurality of terminal devices  30 , the CPU  81  identifies the terminal device  30  which transmitted the game input data, based on the IP address, and moves the operation character of this identified terminal device  30  based on this game input data.  
      Furthermore, if the positional data of operation character of the identified terminal device  30 , out of the plurality of terminal devices  30 , meets predetermined conditions, the CPU  81  transmits, to the identified terminal device  30 , movement signal data which designates the position of the terminal device  30 .  
      In addition, during the game, the CPU  81  extracts the game program, information expressing the status corresponding to the time-line in the game field at the time (namely, information expressing events and the like occurring in the game field) from the database  84  and transmits this to the terminal device  30 , which is the request source, via wireless LAN. In addition, the CPU  81  receives information expressing the operation results of the player from each terminal device  30  and stores this in the memory  82 .  
      The CPU  81  runs the game and stores the progress results of the game program to the database  84 , based on the information expressing the operation results of the player stored to the memory  82 .  
      Here, the information expressing the operation results of the player are, for example, selection results by the player from a selection shown to the player via the terminal device  30 , based on the progress of the game program, or the results of the operation performed by the player of the character appearing in the game, and is information transmitted from the terminal device  30  as a result of the player operating their respective terminal devices  30 . Other players can check the progress status of the current game stored to this database  84  (for example, high-score information, etc.)  
      Configuration of the Sub-Control Device  
       FIG. 21  is a block diagram showing the configuration of the sub-control device  90 .  
      The sub-control device  90  has a CPU  91 , a memory  92 , a wireless communication part  93 , an input and output part  94  which is the interface with the speaker  75 , and a transmission part  64  which is an interface with the sub-monitor  613 , which are connected to a data bus BUS.  
      The wireless communication part  93  includes a transceiving circuit part (RF)  95  for transmitting and receiving signals with the main control device  80 , and a base band processing part  96  for converting RF (Radio Frequency) signals received by the transceiving circuit part  95  into base band signals and also converting base band signals to be transmitted into RF signals.  
      The CPU  91  transmits and receives data with the main control device  80 , via wireless communication part  93 , by the procedure below.  
      Specifically, the CPU  91  divides data into packet data when transmitting data to the main control device. At this time, the IP address of the terminals device  30  which is the transmitting source is added to the packet data as an identifier for identifying respective terminal devices  30 .  
      In addition, the CPU  91  receives the packet data if the IP address added to the packet data matches the IP address of the terminal device, when receiving data from the main control device  80 , and destroys the packet data if it does not match.  
      The CPU  91  not only transmits and receives signals with the main control device  80 , via the wireless communication part  93 , but also controls the sub-display part  61 , tire driving control device  322 , and tire direction control device  323 , based on the input signals from the input operation part  72 , the CCD camera  614 , and the IC tag detection part  324 .  
      Specifically, the IC tag detection part  324  reads positional information from the IC tag  211  and outputs this as current-positional data. The CPU  91  transmits the game input data (data regarding character information, identified selection information, etc.) according to the input on the input operation part  72 , the face image data taken by the CCD camera  614 , and the current-positional data from the IC tag detection part  324  to the main control device  80 .  
      Furthermore, when receiving movement signal data which designates the position of the terminal device  30  from the main control device  80 , the CPU  81  grasps the position of the terminal device  30  on the play area  21 , based on current-positional data from the IC tag detection part  324 , controls the tire driving control device  322  and the tire direction control device  323  of the traveling part  32 , and moves the terminal device  30  to the position designated by the movement signal data.  
      In addition, the CPU  91  can drive the tire driving control device  322  and the tire direction control device  323  of the traveling part  32 , according to the game input data which is input by operating the input operation part  72 .  
      The CPU  91  executes an operation program which is stored to the memory  92 , according to input from the input reception part, based in the program executed by the CPU  81 , and performs various processing. Here, the input operation part  72 , the touch-panel part  613 B and various switches not shown can be given as examples of the input reception part. In addition, the CPU  91  controls the sub-monitor  613  and the like, based on the status of the game sun be the game program.  
      On other words, when receiving a game program or information expressing the status corresponding to the time-line in the game field at that time from the main control device  80 , after storing information on the game program and the like, transmitted from the main control device  80 , to the memory  82 , the CPU  91  presents the various occurrences, such as events, occurring in the game field at this time, in the image display part  613 A of the sub-monitor  613  and outputs sound effects from the speaker  75 .  
      In addition, by operating the input operation part  72  while viewing the game content (image, letter information, etc.) shown in the image display part  613 A of the sub-monitor  613 , the players using respective terminal devices  30  can operate the characters shown in the main display device  22 , participate in the progress of the game by operations such as selecting from a selection by letters, and move the terminal device  30  to an identified position on the play area  21 .  
      The image data generated in the main control device  80  is output from the sub-monitor  613  by the procedure below. When an RF signal is received from the main control device  80 , the transceiving circuit part  95  applies this RF signal to the base band processing part  96  and converts the RF signal to the base band signal. The base band processing part  96  outputs this base band signal to the sub-monitor  613 , via the transmission part  64 . Then, this base band signal is output and shown as an image in the image display part  613 A.  
      In addition, voice signals from the main control device  80  are output as voice from the speaker  75  by the same operation as the foregoing. In other words, the transceiving circuit part  95  converts the RF signal to a base band signal by the base band processing part  96  when receiving an RF signal from the main control device  80 . The base band processing part  96  outputs this base band signal as voice from the speaker  75  by outputting the signal to the speaker  75 , via the input and output part  84 .  
      In addition, the CPU  91  executes operation programs and the like based on input from the input operation part  72  and external input such as detecting the predetermined number of medals, which is a game medium, inserted by the medal insertion detector  735 . Then, the CPU  91  controls the sub-monitor  613  and the like, based on the status of the game executed by the program. For example, if the medal has not yet been inserted, the game status is set to non-playing state and the movement prohibition mechanism controls the sub-monitor  613  and places it in a movement prohibited state, wherein movement outside the sub-monitor storage part  62  is prohibited. Specifically, control for maintaining the storage part cover  66  in a closed state and control for locking the connection device  600  either physically or electronically such that it cannot be driven are performed. Then, when the medal insertion detector  735  detects the insertion of a predetermined number of medals, which is a game medium, the game status becomes a play state, and the movement prohibition mechanism releases the sub-monitor  613  from its movement prohibited state and controls the sub-monitor  613  to enable movement. Specifically, control for opening the storage part cover, control for enabling the sub-monitor  613  to be moved outside of the sub-monitor storage part  62 , and control for releasing the lock on the connection device  600  and enabling the sub-monitor  613  to move are performed.  
      In addition, as described above, the sub-monitor  613  is controlled such that game images cannot be shown in a non-play state and controlled such that game images can be shown when a play state is entered. Here, external input refers particularly to predetermined signals including input signals from the input operation part  72 , and for example, the detection signal of the insertion of a predetermined number of medals, which is a game medium, from the medal insertion detector  715 , the input signals of various switches, and the detection signal from the seating detector  525  when the seating of the player is detected, are given.  
      In addition, as stated above, by receiving predetermined signals from the main control device  80 , the sub-control device  90  controls the connection device driving mechanism and the holding device driving mechanism, and drives the connection device  600  and the holding device  400 .  
      Configuration of the Game Program  
      Next, a game program provided by the game machine  1  is explained. This game program is a role-playing game which is set in a fictional game field which runs continuously by its own time-line. A plurality of towns exists in this fictional game field, and guilds are formed respectively in each town.  
      Each player becomes an adventurer, visits each town, and aims to clear numerous events (quests) waiting in each guild by operating the avatar.  
      On the other hand, this game program generates a plurality of large events (macroquests) in the game field and forms a large plot to the story. Each player becomes involved in the large events (macroquests), while solving the foregoing events (quests), and solves the macroquest with other players while sometimes cooperating, sometimes fighting, and sometimes competing with each other.  
      This game program changes the plot of the game field by the operations of the terminal devices  30  of the players (game-play). In other words, the accumulation of the game-play (adventures) of each individual player creates the history of this game field.  
      In this way, this game program is a role-playing game wherein a plurality of players can all experience the flow of history in a fictional world. In addition, in this game field, history is created by a unique time-line which cannot be stopped, and therefore, the people appearing within this game field are not immortal, but will grow old as in the real world.  
      The game program is configured to write the name of the player who has solved an event in the macroquest or achieved accomplishments such as winning in a competition against another player to a chronology which is stored to the database  84 . Through this, players who were successful in the macroquest can leave their name in the history of the game field.  
      The operation of the game machine  1  is explained, with reference to the main flow chart shown in  FIG. 22 .  
      In ST 1 , each player selects a terminal device  30  of their choice from the terminal devices  30  placed on the play area  21  and sits in the seat  31  of the selected terminal device  30 . Next, in ST 2 , each player inserts a medal, which is one of the game mediums, into the medal insertion part  734  and presses the start switch. Then, in ST 3 , the storage cover  66  opens and the sub-monitor  613  enters a state enabling movement outside. Then, in ST 4 , the locks of the sub-monitor  613  and the seat  31  of the game machine  1  are released and, in ST 5 , the player can adjust the mode of the seat  31 . Next, the sub-monitor  613  is automatically pulled out from the sub-monitor storage part  62  of the side unit  60  to the front of the player, which is a position enabling viewing by the player. Here, various cards, such as credit cards and prepaid cards, electronic money, and various points are given as examples of game media. In addition, other physical insertion includes predetermined actions equivalent to payment of electrical money or points by a method which can be acknowledged electrically.  
      In ST 6 , the game machine  1  executes a game processing, described hereafter. When the game is completed, in ST 7 , the game machine  1  stores the pulled-out sub-monitor  613  in front of the player into the sub-monitor storage part  62  and also returns the mode of the seat  31  to seat mode.  
       FIG. 23  is a flowchart showing one example of the pull-out operation of the sub-display part  61 .  
      As explained above, in ST 110 , each player selects a terminal device  30  of their choice from the terminal devices  30  placed on the play area  21  and sits in the seat  31  of the selected terminal device  30 . The seating detector  525  detects that the player is seated. Next, in ST 120 , each player inserts a medal, which is one of the game mediums, into the medal insertion part  734  and presses the start switch. Then, in ST 125 , the storage cover  66  opens and the sub-monitor  613  enters a state enabling movement outside. Then, in ST 130 , the sub-monitor  613  of the game machine  1  automatically pulled outward from the sub-monitor storage part  62 , placed in front of the player, which is a position enabling viewing by the player, and rotation-driven such that the image display part  613 A faces the player-side. In ST 140 , the position sensor  604 , placed in sub-monitor  613 , detects the position of the player and detects whether the sub-monitor  613  is placed in a state enabling viewing by the player. If the sub-monitor  613  is not placed in a state enabling viewing by the player, the sub-monitor  613  is driven again to place it in a state enabling viewing by the player. If, in ST 150 , the sub-monitor  613  is determined to be in a state enabling viewing by the player, the holding device  400  is driven to engage with the sub-monitor  613 . If the holding device  400  is engaged with the sub-monitor  613 , the game processing is executed in ST 170 . Here, if the holding device  400  is not driven to engage with the sub-monitor  613 , regardless of the sub-monitor being in a state enabling viewing by the player, the position of where the holding device  400  is placed, the operation method for driving the holding device  400 , and the like are shown in the sub-monitor  613 . In this way, the player is notified that the holding device  400  is not engaged with the sub-monitor  613  and predetermined operations for engaging the holding device  400  with the sub-monitor  613  can be prompted.  
      Although the holding device 400  engages with and holds the sub-monitor  613  automatically, as a rule, if the holding device  400  is not engaged with the sub-monitor  613  automatically because of a malfunction of some sort, the position of the holding device  400  and the operations necessary for engaging the holding rod  411  with the sub-monitor  613  are shown in the image display part  613 A of the sub-monitor  613 , and the player can be prompted to engage the holding device  400  with the sub-monitor  613 . As a means for prompting the engagement of the holding device  400 , an illuminating part not shown, placed in the vicinity of the holding device can be flashed on and off.  
       FIG. 24  is a flowchart of the game processing. When the game is started in ST 11 , the game program creates an avatar of the player on ST 12 .  
      In other words, the game program shows an avatar creating screen in the image display part  613 A of the sub-monitor  613 . In this avatar creation screen, the player creates an avatar, which is an alter-ego of the player, when participating in the game program. When an image of the players face is taken by the CCD camera  614  and the player enters personal information and the name to be used in the game field to the input operation part  72 , the game program creates an avatar based on this information and registers it to the database  84  of the main control device  80 .  
      In ST 13 , the game program places the terminal device  30  in which the player is seated in the default position on the play area  21 .  
      In other words, the towns in the game field are surrounded by the ocean or forests, or are large cities. The play area  21  includes a plurality of sub-areas  212 , such as a city area  212 A, an ocean area  212 B, and a forest area  212 C, as stated earlier. These sub-areas  212  are quasi-spaces corresponding to the environment of the towns in the game field.  
      Therefore, the game program sets the town each player is in, in the game field, and moves the terminal device of the player to the sub-areas  212 , corresponding to the town in which each player is, when the game begins. Alternatively, the terminal device  30  of the player is moved according to the operations of each player of the input operation part  72 , and the town in which the player is in the game field is set according to this movement.  
      As explained hereafter, in ST 14 , the game program runs the game according to a unique time-line, generating macroquests in which a plurality of players participate and quests in which only one player participates, and completed the game in ST 15 .  
       FIG. 25  is a flowchart of each player in the game program.  
      Each player can perform an event chronology processing, guild processing, possessions processing, shop processing, status processing, and party processing.

If the player selects a desired town, the game program moves the player to the selected town. When the game program moves the player to another town, the terminal device of each player is moved to the sub-areas  212  of the corresponding transfer destination town.  
      The player can select menus such as “guild”, “possessions”, and “shop”, even in the transfer destination town.  
      When the player selects “possessions”, the game program performs a possessions processing and shows a possessions (list of contents) screen, of weapons, tools, shoes, and the like in the image display part  613 A of the sub-monitor  613 . If the player selects a specific possession in this possessions (list of contents) screen, the game program shows a plurality of items included in the selected possessions in the image display part  613 A of the sub-monitor  613 . The player selects the desired item from these items and either “wear” or “dispose of” the selected item.  
      When the player selects “shop”, the game program performs a shop processing and shows a shop screen in the image display part  613 A of the sub-monitor  613 . This shop screen is a screen for barter exchanging items in possession or acquiring information from the shop owner, and the player can select either “listen” or “exchange”.  
      When the player selects “exchange” in the shop screen, the game program shows a list of products in the image display part  613 A of the sub-monitor  613 . The player can select a desired item from this product list.  
      When the player selects the desired item, the game program shows the items possessed by the player for exchanging with the selected desired item. When the player selects an item in possession for exchange, the game program shows the item posses by the player and the price thereof in the image display part  613 A of the sub-monitor  613 .  
      When the player selects the desired item for exchange from the items in possession, shown here, the desired items in possession to be exchange are collected, and the player selects “execute”, the game program executes an exchange of the desired item and the desired item in possession to be exchanged.  
      On the other hand, if the player selects “listen” in the shop screen, the game program shows “rumors” in the image display part  613 A of the sub-monitor  613 . The player can acquire information in the game field by the “rumors” shown in this screen.  
      When the player selects “status”, the game program performs a status processing and shows a status screen in the image display part  613 A of the sub-monitor  613 . This status screen shows the results of the player&#39;s accomplishments in the game field, the possessions thereof and the like. Specifically, it shows name, title, fame, power, intelligence, number of monsters slain, number of quests cleared, number of people saved, and the like.

       FIG. 26  is a flowchart of the encounter processing when the player encounters another player on the game field.  
      In the progress of the game in ST 14 , the game program executes an encounter processing when the player encounters another player on the game field.  
      In other words, in ST 21 , an encounter screen is shown in the image display part  613 A of the sub-monitor  613 , and the player is prompted to select whether to make contact.  
      If the player selects “No”, the process returns to ST 24  and the encounter processing is terminated without forming a party. On the other hand, if the player selects “Yes”, the process moves to ST 22 , and the game program transmits mail to the other player, and shows that the player is being invited to become a fellow player in the image display part  613 A of the sub-monitor  613  of this player. Then, the game program prompts the other player to select whether to accept the invitation.  
      If the player receiving the invitation selects “Yes”, the process moves to ST 23  and the game program transmits the selected result to the player who is the inviter, shows that the player has become a fellow player in the image display part  613 A of the sub-monitor  613  of the player who is the inviter, a party is formed and the process is completed.  
      On the other hand, if the player receiving the invitation selects “No”, the game program shows that the player could not be a fellow player to the player who is the inviter in the image display part  613 A of the sub-monitor  613 , and the process moves to ST 24 , and terminates the encounter processing without forming a party.  
       FIG. 27  is a flowchart of the macroquest processing when a macroquest is generated in the game field.  
      If a macroquest involving a plurality of players is generated in ST 3 , the game program executes a macroquest processing.  
      In other words, if a macroquest is generated in ST 31 , the process moves to ST 32 , shows the players involved in this macroquest in the main display device  22 , also moves the terminal devices  30  of the players involved in this macroquest to the city area  212 A in front of the main display device  22 , and places them so that the terminal devices  30  of opposing players are close to and facing each other.  
      Specifically, as shown in  FIG. 28 , there are six terminal devices,  30 A to  30 F, placed on the play area  21 . Of these, the players of terminal devices  30 A,  30 B, and  30  E are one party, and the players of terminal devices  30 C,  30 D, and  30 F are another party. Then, each player in terminal devices  30 A to  30 D are caught in the macroquest in the city area  212 A and are placed such that the parties oppose each other. In contrast, because the players in terminal devices  30 E and  30 F are respectively in the ocean area  212 B and the forest area  212 C, they are not involved in the macroquest, and thus, view the battle between the terminal devices  30 A to  30 D.  
      In order to clear the macroquest, the players caught in the macroquest select whether to call for help from fellow players in ST 33 .  
      If the player selects “No”, the process moves to ST  36 .  
      On the other hand, if the player selects “Yes”, the process moves to ST 34 , the game program transmits mail calling for help to the fellow players, and shows that help is being called for in the image display part  613 A of the sub-monitor  613  in the terminal device  30  of the player. Then, the game program prompts the fellow players to select whether to help the player.  
      If the fellow player whose help is requested selects “Yes”, the process moves to ST 35 , and the game program transmits the selection results to the player requesting help and that the fellow player will participate is shown in the image display part  613 A of the sub-monitor  613  of the player. In addition, the game program shows the status of the gathering of newly participating fellow players in the main display device  22 , and the terminal devices  30  of the newly participating fellow players are moved to the city area  212 A in front of the main display device  22  and placed such that the terminal devices  30  of opposing players are close to and facing each other.  
      On the other hand, if the player whose help is requested selects “No”, the game program shows that help had been denied in the image display part  613 A of the sub-monitor  613  of the player requesting for help, and the process moves to ST 36 .  
      Specifically, as shown in  FIG. 29 , because the player in terminal device  30 E is fellow players with the players in terminal devices  30 A and  30 B, this player&#39;s help is requested by the terminal devices  30 A and  30 B. The player in terminal device  30 E, having agreed to help, is moved to the city area  212 A and is placed in alignment with the terminal devices  30 A and  30 B.  
      On the other hand, although the player in terminal device  30 F is fellow players with the players in terminal devices  30 C and  30 D, and this player&#39;s help is requested by the terminal devices  30 C and  30 D, he refuses to help and, therefore, remains in the forest area  212 C.  
      In ST 36 , each player fights the opposing player or opposing party. Specifically, as shown in  FIG. 29 , the players of terminal devices  30 A,  30 B, and  30 E and the players of terminal devices  30 C and  30 D fight in the city area  212 A.  
      In this way, each player gets caught in a macroquest or are requested to help by fellow players caught in the macroquest, and whether to watch the battle between other players or to personally participate can be selected.
