## Background
1. Field of the Invention

The present invention relates to an air hockey game apparatus with which game players compete with each other in hitting a puck into a goal. Particularly, the invention relates to an air hockey game apparatus that has a puck sliding surface having blowholes for blowing air to float the puck, an air-blower for blowing and sending the air toward the blowholes, a puck-reflecting frame provided on the puck sliding surface, and goals provided on the puck sliding surface.

2. Description of the Related Art

Hitherto, hockey game apparatuses have been suggested and are being sold. For example, Japanese Unexamined Patent Publication No. 8-299584 discloses an air hockey game apparatus that allows game players to hit a puck into a goal at the end of the opponent on a field having a large number of air-blowholes. The apparatus includes installation portions, electrical display units, and an audio output device. The installation portions are individually provided at two lateral portions in the middle of two sides of the field. The electrical display units display scores, and are provided above the field in a central portion of cylindrical support members extending from the installation portions at the two lateral portions. The audio output device produces sounds corresponding to the contents of the game.

However, problems arise in the described configuration. The electrical display units for displaying scores, which are provided above the central portion of the field made of a puck sliding surface, are effective to allow spectators to recognize the game progress status. To the game players however, the display units provide adverse effects.

The display units are ineffective to allow the game players to appropriately recognize the game progress status. The game players keep their eyes on the movement of the puck on the puck sliding surface, and their eyes must turn away from the movement of the puck to look up the electrical display units provided above the puck sliding surface. In other words, displays on the electrical display units hinder the progress of the game by the game players.

Under these circumstances, an object of the present invention is to provide an air hockey game apparatus that allows game players to appropriately recognize a game progress status, thereby effectively improving amusement characteristics of the game.

An air hockey game apparatus of the present invention has a puck sliding surface having blowholes for blowing air to float a puck and at least one transparent portion; an air-blower for blowing and sending air toward the blowholes; a puck-reflecting frame around the puck sliding surface; goals on the puck sliding surface; and display sections provided under the transparent portion, of which the display mode is changeable. Also, the air hockey game apparatus has a display-mode-setting unit for setting the display mode of the display sections, thereby controlling the display sections so as to be in the set display mode.

According to the described arrangement, the display sections under the transparent portion of the puck sliding surface display the display mode set by the display-mode-setting unit and change the display mode as required, thereby allowing game players to appropriately recognize predetermined information.

In the above arrangement, the air hockey game apparatus may further include display-mounting plates under the transparent portion so as to oppose positions where game players stand, wherein the display sections are provided on the display-mounting plates. This allows the game players to effectively view the display sections provided on the installation boards, thereby allowing the game players to appropriately recognize the predetermined information.

Also, an arrangement may be such that the described air hockey game apparatus further includes spaces partitioned by partitions individually having the display-mounting plates, and guide openings on the partitions for guiding the air transferred from the air-blower. According to this arrangement, the air from the air-blower to the aforementioned spaces is guided into guide openings provided on the partitions, and the air is transferred to blow onto the puck sliding surface from the blowholes.

Also, the air hockey game apparatus may further include a puck detector in at least one portion of the puck-reflecting frame, wherein the display-mode-setting unit sets the display modes of the display sections. According to this arrangement, the display modes of the display sections change corresponding to movement of the puck detected by the puck detector provided in at least one portion of the puck-reflecting frame. This provides dynamic characteristics to the game.

Also, the described air hockey game apparatus may further include goal-detecting units for detecting entry of the puck into the goals, wherein the display-mode-setting unit sets the display modes according to detection signals outputted by the goal-detecting units. According to this arrangement, corresponding to detection by the goal-detecting units for entry of the puck into the goals, the display modes of the display sections change. Therefore, the game players can effectively recognize their goal acquirement.

Also, the described air hockey game apparatus may be arranged such that the display sections display scores. This arrangement allows the game players to appropriately recognize the scores displayed in the display sections, thereby allowing an effective improvement in amusement characteristics of the game.

Also, in the describe air hockey game apparatus, the puck detector for detecting movement of the puck may be provided so as to oppose the puck sliding surface, and the display-mode-setting unit may be arranged to set the display modes of the display sections when the puck detector detects movement of the puck. According to this arrangement, the display modes of the display sections change corresponding to movement of the puck detected by the puck detector provided so as to oppose the puck sliding surface. This allows dynamic characteristics to be provided to the game.

Also, the described air hockey game apparatus may be arranged such that the puck detector for detecting passage of the puck is provided so as to oppose one portion of the puck sliding surface, in which the display-mode-setting unit sets the display modes when the puck detector detects passage of the puck. According to this arrangement, when the puck is hit toward the installation portions of the puck detector, the display modes of the display sections change, thereby allowing dynamic characteristics to be provided to the game.

Also, the described air hockey game apparatus may be arranged such that the puck detector is individually made of a plurality of light-sensitive detectors provided under the puck sliding surface, the puck detectors detect the direction in which the puck passes, and the display modes are changed corresponding to the direction in which the puck passes. According to this arrangement, the puck detector detects the direction in which the puck passes, and the display modes of the display sections change corresponding to the direction in which the puck passes. This allows an effective improvement in amusement characteristics of match games to be played by two game players.

Also, in the described air hockey game apparatus, the display-mode-setting unit may be arranged to determine a game status, and the display sections may be arranged to display the game status. According to this arrangement, the display modes of the display sections change corresponding to the game status, thereby allowing the game players to appropriately recognize the game status.

Also, the described air hockey game apparatus may further include a display-mode-setting unit made of a timer, wherein the display modes of the display sections are changed corresponding to time measured by the display-mode-setting unit. According to this arrangement, time measured by the timer is displayed on the display sections, thereby allowing the game players to effectively recognize the time.

Furthermore, in the described air hockey game apparatus, the timer constituting the display-mode-setting unit may be arranged to measure time passing in the game, and the display sections may be arranged to display remaining time of the game corresponding to the time passing in the game. According to this arrangement, the game players can recognize final stages of the game according to the remaining time of the game, thereby providing tension characteristics to the game.

FIGS. 1 and 2 show the overall configuration of an air hockey game apparatus according to the present invention.

The air hockey game apparatus has a base 1, a puck sliding surface 2, a peripheral wall section 3 (puck-reflecting frame), a pair of side blocks 4, and an upper block 6. The puck sliding surface 2 is mounted on the base 1. The peripheral wall section 3 surrounds the puck sliding surf ace 2, thereby forming a puck-reflecting frame. The side blocks 4 are provided at right and left side sections of the peripheral wall section 3. The upper block 6 is supported by supporting frames 5 mounted on the pair of side blocks 4. Goals 7 are individually provided at two ends in the front-to-rear direction on the puck sliding surface 2. The individual goals 7 have openings which oppose each other, toward which the puck is hit.

An air-blower 13 (to be described below) for transferring air toward the puck sliding surface 2 is provided in the base 1. Air transferred by the air-blower 13 blows upward from blowholes 40 formed of many small openings (shown in FIG. 3) on the puck sliding surface 2, thereby floating the puck which is shaped like a disc. With the puck floating, individual game players, each holding a hitting tool called a mallet, hit the puck into the goals 7 at the sides of the game player acting as an opponent, thereby competing for scores.

Score displays 8 for displaying scores of the game players are provided on at least one of the side blocks 4. Also, illuminators (not shown) are provided. The illuminators include, for example, spotlights for emitting light toward predetermined positions on the puck sliding surface 2, such as toward the goals 7. An audio unit 9 includes, for example, speakers for producing sound.

The puck sliding surface 2 is formed of a material, such as an acrylic-resin transparent board, which has transmissive characteristics. Also, as shown in FIGS. 3 and 4, a horizontal plate 11, a pair of sloping plates 12 (display-mounting plates), a pair of sloping plates 28 (partitioning plates), and the air-blower 13 are provided under a central portion 10 of the puck sliding surface 2. The horizontal plate 11 has a predetermined width and extends in a right-to-left direction along a lower surface of the puck sliding surface 2. The individual sloping plates 12 extend diagonally downward from the front and rear ends of the horizontal plate 11. The individual sloping plates 28 extend diagonally upward from ends of the sloping plates 12. The air-blower 13 consists of a blowing fan 41 and a driving motor 42 and is provided under the horizontal plate 11.

The horizontal plate 11 has three large openings 14 serving as air-communicating openings, and two small openings 15 are provided between the large openings 14. Three luminophors 16 (display sections) made of light-emitting diodes are provided so as to face the large openings 14. Four puck detectors 17 individually made of light-sensitive detectors are provided around each of the large openings 14. The puck detectors 17 oppose the puck sliding surface 2 so as to detect the movement of the puck. When the luminophors 16 are turned on to illuminate or to blink, light is emitted upward through the large openings 14 and the puck sliding surface 2 which is transparent. According to this arrangement, the game players can visually recognize the positions where the puck detectors 17 are installed.

Each of the sloping plates 12 has three openings 18 at positions corresponding to the puck detectors 17, and segmented roulette displays 19 are provided so as to face the openings 18. The roulette displays 19 are mounted on the display-mounting plates, i.e., on the sloping plates 12, so as to oppose positions where game players stand at the front end and the rear end of the base 1. Thus, in the above arrangements, the roulette displays 19 are visible through the puck sliding surface 2 which is transparent. Therefore, the game players can see digits or other items displayed on the roulette displays 19.

Also, under the transparent puck sliding surface 2, spaces partitioned by partitioning plates formed of the sloping plates 12, which individually form the display-mounting boards, and the sloping plates 28 are provided. The individual sloping plates 28 have guide openings 48 for guiding air transferred from the air-blower 13. The transferred air is guided into the abovementioned spaces from the guide openings 48 formed on the sloping plates 28 (partitioning plates), the air is then guided to blow up from the puck sliding surface 2 from the blowholes 40 provided on the puck sliding surface 2. In a preferable arrangement, the horizontal plate 11, the sloping plates 12 and 28, the luminophors 16, the puck detectors 17, and the roulette displays 19 are integrated as a single unit. This is preferable because the unit is removable from the base 1.

As shown in FIGS. 5 and 6, each of the goals 7 has an upper cover 43, a puck-passing opening 44, and a goal sensor 35 (goal-detecting unit) (see FIG. 10). The upper cover 43 is provided so as to partly extend inward from the peripheral wall section 3 at positions at the front and rear ends of the puck sliding surface 2, and the puck-passing opening 44 has a cut opening formed. The goal sensor 35, which is made of a passing sensor or the like, is provided in the puck-passing opening 44 and senses the puck hit into the goal 7. For the above, an alternative arrangement may have a goal having a concave section or a convex section on either the puck sliding surface 2 or the peripheral wall section 3. Another alternative arrangement may be such that a goal is simply marked, or a collision sensor or impact sensor may be used as a goal sensor.

Each of the goals 7 also has components such as a supporting bracket 45, a supporting axis 20, a blocking member 21, a driving motor 22, and a power transmission mechanism. The supporting bracket 45 is provided inside the upper cover 43. The supporting axis 20 is symmetric with respect to its right and left sides, extends vertically, and is fitted to the supporting bracket 45. The blocking member 21 is rotatably supported by a vertical axis, that is, the supporting axis 20. The blocking member 21 is formed in an arcuate shape. It has a blocking face spreading as an arc with the vertical axis in the center. The power transmission mechanism consists of components such as a gearbox 23 to be driven by the driving motor 22.

With the above configuration, driving power transferred from the driving motor 22 to the gearbox 23 is transmitted via a driving gear 23a to a driven gear 21a fitted to the blocking member 21. Thereby, the blocking member 21 is allowed to be gradually rotationally displaced from a fully open position shown in FIG. 7 to a semi-open position shown in FIG. 8, and to a completely-shut position shown in FIG. 9.

With the blocking member 21 in the fully open position, an opening 24 provided in the goal 7 becomes fully open, in which state scoring is easiest. In contrast, with the blocking member 21 in the semi-open position, the opening 24 is formed slightly larger than the puck (not shown) in a central portion of the goal 7, thereby causing scoring to be the most difficult. With the blocking member 21 in the completely-shut position, the size of the opening 24 may be set such that the puck cannot enter the goal 7.

The supporting bracket 45 has angle detectors 25 and transmission gears 26. Each of the angle detectors 25 is made of a rotational variable resistor. Each of the transmission gear 26 engages with the driven gear 21a, and is rotationally driven according to the rotational displacement of the blocking member 21. The rotational angle of the blocking member 21 is detected by the angle detector 25. Also, stoppers are provided, each consisting of a rotation-stopping plate 27 mounted on an upper surface of the blocking member 21 and a pair of engaging pins (not shown) provided on the supporting bracket 45 so as to protrude. Also, each of the stoppers restricts the rotational range of the blocking member 21, thereby preventing the blocking member 21 from rotating beyond the range between the fully open position and the completely-shut position of the goal 7.

The described air hockey game apparatus has a control unit 34 (control unit) for outputting control signals to the air-blower 13, thereby controlling the air-blowing condition. The control unit 34 has a handicap-mode controller 32 and a roulette-mode controller 33. The handicap-mode controller 32 controls a handicap mode that differentiates the open sizes of the goals according to a signal inputted via operating selection buttons 31. The handicap-mode controller 32 allows the roulette displays 19 to operate according to movement of the puck, and in addition, controls the roulette mode that changes the open sizes of the goals 7 according to results of operation of the roulette displays 19.

The respective selection buttons 31 are, as shown in FIG. 2, a push button for selecting the handicap mode and a push button for selecting the roulette mode. Before the game is started, a user inputs operations using the selection buttons 31 to set a game mode. For the selection buttons 31, a push button for selecting a normal mode may be provided which is used for playing the air hockey game in a normal mode.

The handicap-mode controller 32 is arranged as described in the following paragraphs.

When the handicap mode is selected according to operations of the selection buttons 31, the handicap-mode controller 32 outputs a control signal to the driving motor 22 that drives the blocking members 21, thereby fully opening the goal 7 provided at one end of the puck sliding surface 2. The abovementioned end is assumed to be the end of a first game player. Concurrently, the handicap-mode controller 32 drives the goal 7 provided at the other end of the puck sliding surface 2 to the completely shut state. The abovementioned end is assumed to be the end of a second game player. In this way, the game is started.

During the game, when a score is recognized according to a detection signal outputted from the goal sensor 35 which is formed of the passing sensor, the handicap-mode controller 32 outputs a control signal to the driving motor 22. The control signal changes the open sizes of the goals 7 so that game players can play a game which is suitably adjusted to the difference in skill of the game players. Concurrently, the handicap-mode controller 32 outputs control signals to configuration members, such as the score displays 8, the audio unit 9, the luminophors 16, and the roulette displays 19.

The roulette-mode controller 33 drives the two goals 7 to the completely shut state when the game is started. When movement of the puck is detected by the puck detectors 17, the roulette-mode controller 33 drives the roulette displays 19 to change digital displays. Then, the roulette-mode controller outputs a control signal that drives the goal 7 at the end of the opposing game player to the fully open state, thereby changing the game mode to a chance mode. Concurrently, the roulette-mode controller 33 outputs control signals to other members, such as the audio unit 9, the luminophors 16, and the roulette displays 19, thereby allowing a predetermined performance to be executed.

Hereinbelow, with reference to a flowchart in FIG. 11, a description will be given of basic control processing to be executed by the control unit 34.

When the basic control processing is started, step ST1 determines if coins are entered in a coin-entry opening provided at a predetermined position of the air hockey game apparatus. If step ST1 determines the condition to be YES, processing control is passed to step ST2. Step ST2 commands the score display 8 and the roulette displays 19 to individually display a selection time Ta for allowing a game mode to be selected.

Subsequently, step ST3 determines if the selection time Ta is less than a reference time A preset to approximately 30 seconds. If the step ST3 determines the condition to be YES, processing control is passed to step ST4. Step ST4 determines if a first selection button for selecting the handicap mode is turned ON. If step ST4 determines the condition to be NO, processing control is passed to step ST5. Step ST5 determines if a second selection button for selecting the roulette mode is turned ON. If step ST5 determines the condition to be YES, processing control is passed to step ST6. Step ST6 controls the handicap mode described below.

If step ST3 determines the condition to be NO, verifying that the time elapses post the reference time A while neither of the first and second selection buttons is turned ON, step ST7 controls the roulette mode. Step ST7 also controls the roulette mode if step ST4 determines the condition to be YES, verifying that the second selection button is turned ON.

Hereinbelow, with reference to a flowchart in FIG. 12, control processing in the handicap mode is described.

Upon starting the control processing, step ST10 performs initialization, resetting various existing values, such as control values. Then, step ST11 causes the goal 7 at the end of a first game player 1P to be in the fully open state. Subsequently, step ST12 outputs a control signal that drives the goal 7 at the end of a second game player 2P to the completely shut state with an opening/closing driving unit made of the driving motor 22.

In step ST13, the air-blower 13 starts blowing air toward the air-communicating openings of the puck sliding surface 2. In step ST14, the roulette displays 19 change numbers digitally displayed. In step ST15, a game time Tg is measured. Subsequently, according to a detection signal outputted by the goal sensor 35, step ST16 determines if one of the first and second game players 1P and 2P has scored a goal. If step ST16 determines the condition to be YES, processing control is passed to step ST17. ST17 controls a goal performance described below. Subsequently, step ST18 determines if the score is lower than a predetermined final score B.

If step ST16 determines the condition to be NO, verifying that no goal has been scored, processing control is passed to step ST19. Step ST19 determines if the game time Tg is less than a predetermined termination time G. Step ST19 also determines the same condition as above if step ST18 determines the condition to be YES, verifying that the score is lower than the predetermined final score B. If step ST19 determines the condition to be YES, it returns processing control to step ST16 so that the described control processing is repeated.

If step ST18 determines the condition to be NO, verifying that the goal score gained by one of the first and second game players 1P and 2P is higher than the final score B, processing control is passed to step ST20. Step ST20 controls an ending performance, and then terminates the control processing. Step ST20 is also performed if step ST19 determines the condition to be NO, verifying that the game time Tg is greater than the termination time G.

Hereinbelow, with reference to a flowchart in FIG. 13, a description will be given of control processing in the goal performance executed in step ST17 in the handicap mode.

Upon starting the control processing, step ST21 determines which one of the first and second game players 1P and 2P has scored the goal. As a result of the determination in step ST21, if the goal score is verified to have been gained by the first game player 1P, step ST22 commands the audio unit 9 to output predetermined sounds, and also, step ST23 commands a first luminophor to blink. The first luminophor is made of light-emitting diodes arranged in the peripheral wall section 3 at the end of the first game player 1P.

Also, step ST24 adds "1" to a score X1 gained by the first game player 1P and displays it on the score displays 8. Then, step ST25 determines if the open size of the goal 7 at the end of the first game player 1P is smaller than in the fully open state, that is, if a handicap H1 of the first game player 1P is smaller than a maximum value Max. If step ST25 determines the condition to be YES, processing control is passed to step ST26. Step ST26 adds "1" to the handicap H1, thereby increasing the open size of the goal 7 at the end of the first game player 1P by one step. This results in an increase in scoring capacity for the second game player 2P.

As a result of the determination in step ST21, if the goal score is verified to have been gained by the first game player 2P, step ST27 commands the audio unit 9 to output predetermined sounds, and also, step ST23 commands a second luminophor to blink. The second luminophor is made of light-emitting diodes arranged in the peripheral wall section 3 at the end of the second game player 2P.

Also, step ST29 adds "1" to a score X2 gained by the second game player 2P and displays it on the score displays 8. Then, step ST30 determines if the open size of the goal 7 at the end of the first game player IP is greater than that in the completely shut condition, that is, if a handicap H1 of the first game player 1P is greater than a minimum value Min. If step ST30 determines the condition to be YES, processing control is passed to step ST31. Step ST31 subtracts "1" from the handicap H1, thereby reducing the open size of the goal 7 at the end of the first game player 1P by one step. This results in a decrease in scoring capacity for the second game player 2P. Subsequently, step ST32 displays scores gained by the first and second game players 1P and 2P on the score displays 8 and the roulette displays 19, and thereafter, processing control is returned so as to perform control for the handicap mode shown in FIG. 12.

Hereinbelow, with reference to a flowchart in FIG. 14, a description will be given of control processing in the ending performance executed in step ST20 in the handicap mode.

Upon starting the control processing, step ST33 resets an ending time Te to zero, step ST34 commands the audio unit 9 to output sounds, and step ST35 stops the air-blower 13 to terminate air-blowing. Subsequently, step ST36 compares a score X1 gained by the first game player 1P and a score X2 gained by the second game player 2P upon completion of the game. If step ST36 verifies the two scores X1 and X2 to be the same, processing control is passed to steps ST37, and then to ST38. Step ST37 commands all the luminophors provided in the peripheral wall section 3 to blink. Step ST38 commands the individual roulette displays 19 to display "END".

If step ST36 verifies that the score X1 gained by the first game player 1P is higher than the score X2 gained by the second game player 2P, that is, the first game player 1P has won the game, processing control is passed to step ST39. ST39 commands the first luminophor at the end of the first game player 1P to blink. Subsequently, step ST40 commands the roulette displays 19 to display "1P" and the like.

If step ST36 verifies that the score X1 gained by the first game player 1P is lower than the score X2 gained by the second game player 2P, that is, the second game player 2P has won the game, processing control is passed to step ST41. Step ST41 commands the second luminophor at the end of the second game player 2P to blink. Subsequently, processing control is passed to step ST42 that commands the roulette displays 19 to display "2P" and the like.

Subsequently, step ST43 commands the score displays 8 to display the respective scores X1 and X2 gained by the first and second players P1 and P2. Step ST44 determines if the ending time Te exceeds a predetermined reference time E. If step ST44 determines the condition to be NO, processing control is passed to ST45. Step ST45 adds "1" to the ending time Te and returns processing control to step ST34 so that the control processing is repeated.

If step ST44 determines the condition to be YES, processing control is passed to step ST46. In step ST46, a control signal for driving the two goals 7 to the fully open state is outputted to the driving motor 22. Subsequently, step ST47 executes termination control including tasks for turning off all the individual displays and so forth, then returns processing control, thereby terminating the control processing.

Hereinbelow, with reference to a flowchart in FIG. 15, a description will be given of control processing in the roulette mode.

Upon starting the control processing, step ST50 performs initialization, resetting various existing control values and commanding the two goals 7 to be in the completely shut condition. Subsequently, step ST51 commands the air-blower 13 to blow air toward air-communicating openings of the puck sliding surface 2, and step ST52 stops the roulette displays 19. Then, step ST53 starts measurement of the game time Tg.

Subsequently, step ST54 determines if one of the first and second game players 1P and 2P has scored a goal according to a detection signal outputted by the goal sensor 35. If step ST54 determines the condition to be YES, processing control is passed to step ST55. Step ST55 controls the goal performance. Thus, the control processing in the goal performance in the roulette mode is the same as the control processing in the handicap mode except for the following. The control processing in the roulette mode does not include a determination of and the changing operations for the handicap H1 which are performed in steps ST25, ST26, ST30, and ST31 in FIG. 13.

Step ST56 determines if the score is lower than a predetermined final score B. If step ST56 determines the condition to be NO, verifying that the score gained by one of the first and second game players 1P and 2P is higher than the final score B, processing control is passed to step ST57. Step ST57 performs the ending performance shown in FIG. 14, then the control processing terminates.

If step ST54 determines the condition to be NO, verifying that no goals are scored, processing control is passed to step ST58. Step ST58 determines if the puck detectors 17 have detected passage of the puck. Step ST58 is also performed if step ST56 determines the condition to be YES, verifying that the score is lower than the final score B.

If step ST58 determines the condition to be YES, processing control is passed to step ST59. Step ST59 performs control for the roulette performance, and passes processing control to step ST60. Step ST60 determines if the game time Tg is less than a predetermined termination time G. If step ST60 determines the condition to be YES, verifying that the game time Tg is greater than the termination time G, processing control is passed to step ST57, and the control processing terminates.

Hereinbelow, with reference to a flowchart in FIG. 16, a description will be given of control processing in roulette performance performed in step ST59 described above.

Upon starting the operation control, step ST61 determines if the puck detectors 17 have detected the puck hit by the first game player 1P. Specifically, step ST61 determines the direction in which the puck passes according to the order in which detection signals are outputted by the puck detector 17 made of the four light-sensitive detectors provided around the large openings 14. According to the direction determined, step ST61 performs the determination described above.

If step ST61 determines the condition to be YES, verifying that the puck detector 17 has detected the puck hit by the first game player 1P, processing control is passed to step ST62. Step ST62 sets a flag P1 for identifying that game player is set to "1P". On the other hand, if step ST61 determines the condition to be NO, verifying that the puck detector 17 has detected the puck hit by the second game player 2P, processing control is passed to step ST63. Step ST63 sets the flag P1 for identifying the game player to "2P".

Subsequently, step ST64 resets an execution time Tr for roulette performance to zero, commands the roulette displays 19 to operate, and passes processing control to step ST65. Step ST65 determines if the execution time Tr is the same as or greater than a predetermined reference time R. If step ST65 determines the condition to be NO, processing control is passed to step ST66. Step ST66 adds "1" to the execution time Tr and passes processing control to step ST66a that awaits an input for a predetermined period of time and returns processing control to step ST65.

Also, an arrangement may be such that the control unit 34 includes a display-mode-setting unit made of a timer, in which the display modes of the display sections are changed corresponding to time measured by the display-mode-setting unit. This arrangement effectively allows the game players to recognize the time measured by the display-mode-setting unit. An example arrangement may be such that the timer measures time passing in the game, and remaining time of the game is displayed. This arrangement allows the game players to recognize, for example, that the game is in a final stage, thereby allowing tension characteristics to be provided to the game.

Also, the described embodiment has the blocking members 21 in the goals 7, sets of opening/closing driving units individually having driving motors 22 that drive the opening/closing driving units to change the open angles of the goals 7, and the controller made of the control unit 34 for controlling the driving motors 22. In this arrangement, the blocking members 21 are individually driven by the driving motors 22, and the goals 7 are individually opened or shut by the driving motors 22, thereby changing the open angles of the goals 7. This provides dynamic characteristics to the game, thereby improving amusement characteristics of the game. Concurrently, the open angles of the goals 7 can be easily changed even during the game.

For example, as in the described embodiment, the open angles of the goals 7 are gradually changed corresponding to scores gained by the game players so that one of the game players who has gained a higher score is placed in a disadvantageous position. This arrangement is advantageous in that the game can be played for fair and strong competition, and thereby, effective improvement in amusement characteristics can be achieved. In the above embodiment, the description has been given of the arrangement in which only the open angle of the goal 7 at the end of the first game player 1P according to scores gained by the first and second game players 1P and 2P in control in the handicap mode. However, there are no restrictions to the above. In this regard, an arrangement may be such that the open angle of the goal 7 at the end of the second game player 2P is changed, or the open angles of the goals 7 at the ends of both the first and second game players 1P and 2P are changed.

Also, although the described embodiment has the pair of goals on the puck sliding surface 2, there are no restrictions to it. For example, only one of the single goals 7 may be provided to allow a single game player to enjoy the game.
