Description

  The present invention relates to an operation device for a game machine that detects the operation amounts of a plurality of operation members using a sensor that outputs a measurement value corresponding to a distance to a detection target.

  When detecting operation of an operation member using a non-contact type sensor such as a magnetic sensor or photoelectric sensor, mechanical error such as shape error or assembly error of the operation member or its related parts, or change in external environment such as temperature or humidity An error occurs in the measured value of the sensor due to the change in sensor characteristics accompanying the. Therefore, in order to correctly detect the operation of the operation member, it is necessary to compensate for the influence of the mechanical error and the change in the external environment on the measurement value of the sensor to ensure the detection accuracy. As an example of realizing such compensation, in the case where the displacement amount of each of a plurality of keys is detected by a light emitting element and a light receiving element, measurement output from the light receiving element in a non-key-pressed state in which the key is not operated. The value is set as an initial value serving as a reference for detection, and the measurement value in the non-key-pressed state is detected at an appropriate time while detecting the key operation amount based on the change amount of the measurement value from the initial value, An operation device that updates an initial value based on the detection result is known (see, for example, Patent Document 1).

Japanese Patent No. 5327673

  FIG. 1 shows an external configuration of a game machine in which an operation device according to one embodiment of the present invention is incorporated. The game machine 1 includes a housing 2, a display device 3 attached to the housing 2, and an input device 4 provided on the front side of the display device 3. As the display device 3, for example, a flat panel display such as a liquid crystal monitor is used. The display device 3 is attached to the housing 2 with its display surface facing obliquely upward. The input device 4 includes a keyboard unit 5. The keyboard unit 5 is positioned at the user's hand when the user stands in front of the housing 2 so as to face the display device 3, and extends from one end portion in the left-right direction of the display device 3 to the other end portion. Is provided. Hereinafter, when the direction is specified with the user as a reference, the direction when the user stands with the display device 3 facing the display device 3 is assumed unless otherwise specified. A pair of left and right speakers 6 are provided on the upper end side of the display device 3 of the housing 2. The input device 4 is provided with various input devices such as a push button switch and a card reader in addition to the keyboard unit 5, and description thereof will be omitted.

  Next, a specific configuration of the keyboard unit 5 will be described with reference to FIGS. As shown in FIG. 2, the keyboard unit 5 includes a base 10 and a plurality of keys 11 as an example of an operation member provided on the base 10. The base 10 functions as a support structure that attaches the keyboard unit 5 to the housing 2. The keys 11 are attached to the base 10 so as to be arranged at regular intervals in the left-right direction of the housing 2 (corresponding to the left-right direction in the figure). Note that FIG. 2 shows a part of the keyboard unit 5 in an enlarged manner. Actually, a larger number of keys 11 are provided in the keyboard unit 5. The shape and size of the key 11 are equal to each other. The upper surface of the key 11 is planar throughout.

  As shown in FIG. 3, the base 10 is attached to a pair of front and rear beams 12 extending in the left-right direction of the housing 2, a top plate 13 attached to the upper surface side of the beams 12, and a lower surface side of the beam 12. The bottom plate 14 is provided. In the base 10, a pair of LEDs 15 for illuminating the key 11 from below is provided. The key 11 has a basic shape that is a long and narrow rectangular parallelepiped shape like the key of a keyboard instrument. The key 11 is disposed on the top plate 13 of the base 10 so that the longitudinal direction (the left-right direction in FIG. 3) coincides with the front-rear direction of the housing 2. FIG. 3 shows a single key 11 and the configuration around the key 11, but the other keys 11 and the configuration around them are the same. The key 11 has a solid block shape in which the inside is clogged. However, the key 11 may be formed in a box shape that is hollow inside and opens downward. The material of the key 11 may be appropriately selected. In this embodiment, since the pressing operation of the key 11 is detected using a magnetic sensor, the key 11 is formed of a nonmagnetic material such as plastic. Moreover, in order to make the key 11 emit light entirely with the illumination light of the LED 15, the key 11 is formed of a material having an appropriate scattering property to diffuse the illumination light.

  A support mechanism 20 is provided between the base 10 and the key 11. The support mechanism 20 includes a coil spring 21 as an example of an elastic body disposed between the front end portion 11 a and the rear end portion 11 b of the key 11 and the top plate 13 of the base 10. A coil spring 21 is provided for each key 11. Therefore, the keys 11 can be individually pushed toward the base 10. The spring characteristics and dimensions of all the coil springs 21 are the same. When the key 11 is pushed downward, the coil spring 21 is bent, and the key 11 is pushed back by the repulsive force against the elastic deformation of the coil spring 21. Since both ends 11a and 11b in the longitudinal direction of the key 11 are supported by the same coil spring 21, the key 11 is pushed in almost in the same manner regardless of the position of the key 11 in the longitudinal direction. It is possible. The support position by the coil spring 21 is as close to the longitudinal end of the key 11 as possible. Therefore, the LED 15 described above is disposed at a position biased toward the longitudinal center side of the key 11 relative to the coil spring 21.

  An upward projecting portion 13 a is provided at the center in the front-rear direction of the top plate 13. The downward movement of the key 11 is restricted by contact between the protruding portion 13a and the lower surface of the key 11. That is, the protrusion 13a functions as a lower stopper when the key 11 is pushed. As shown in FIG. 3, a pair of stopper rods 16 extending downward are provided at positions on the lower surface side of the key 11 that are slightly deviated toward the center in the longitudinal direction from the position where the coil spring 21 contacts. . The stopper rod 16 passes through the top plate 13 and is inserted into the base 10, and a claw 16 a at the tip (lower end) is fitted into a recess 12 a provided in the beam 12. In a state where the key 11 is not pushed in (hereinafter sometimes referred to as an unoperated state), the claw 16a meshes with the upper end of the recess 12a. Thereby, the upward displacement of the key 11 is prevented. That is, the stopper rod 16 and the recess 12a function as an upper stopper that prevents the key 11 from being pulled upward. The elastic body is not limited to the coil spring 21. For example, various elastic bodies such as a sponge-like resin block, rubber, elastomer, and the like may be provided in the support mechanism 20 instead of or in addition to the coil spring 21.

  The keyboard unit 5 is further provided with an operation detection mechanism 30 for detecting the pressing operation of the key 11. The operation detection mechanism 30 includes a magnetic sensor 31 as an example of a sensor attached to the mounting base 17 in the base 10 so as to be positioned below the protruding portion 13 a of the top plate 13, and the magnetic sensor 31 and the top plate 13. And a magnet 32 as an example of a detection target attached to the key 11 so as to face each other. A magnetic sensor 31 is provided for each key 11. The magnet 32 is a permanent magnet. The magnetic sensor 31 outputs a measurement value corresponding to the distance from the magnet 32. The magnetic sensor 31 and the magnet 32 are provided between the positions where the key 11 is supported by the coil spring 21 and the distance between the coil springs 21 is roughly divided into two. That is, the detection position of the pushing operation by the operation detection mechanism 30 is set at the center in the longitudinal direction of the key 11. Even if the key 11 is tilted and pushed in, the central portion in the longitudinal direction is hardly affected. Therefore, if the magnetic sensor 31 and the magnet 32 are arranged at such a position, it is advantageous in suppressing variation in detection sensitivity of the pushing operation. is there. The above-described LED 15 is also attached to the mounting base 17.

  On the lower surface side of the key 11, a pressing rod 18 that extends in the direction of the pressing operation (downward in the illustrated example) is provided. The pressing rod 18 penetrates the base 10 and its tip (lower end) protrudes below the bottom plate 14 when the key 11 is not operated. A click feeling imparting mechanism 40 is provided on the lower surface side of the base 10. The click feeling imparting mechanism 40 includes a micro switch unit 42 attached to the bottom plate 14 of the base 10 via a bracket 41. In the micro switch unit 42, the internal contact is switched from the intermittent state (off) to the conductive state (on) in accordance with the pushing operation of the operation member 42a, and the operation member 42a is clicked in conjunction with the switching of the internal contact. This corresponds to an example of a contact type switch unit to be provided. Various switch units of this type are provided on the market, and an appropriate switch unit may be employed in the click feeling imparting mechanism 40. The micro switch unit 42 is provided such that its operating element 42 a comes into contact with the pressing rod 18 and is pushed downward when the key 11 is pushed. When the operation amount of the pressing operation of the key 11 reaches a predetermined amount, a click feeling is given to the operation element 42a. Since the click feeling imparting mechanism 40 can be provided by using a commercially available microswitch unit, even in a configuration in which a large number of keys 11 are provided, compared to the case where a click feeling imparting mechanism having a unique structure is constructed. A click feeling imparting mechanism can be configured easily and inexpensively.

  Next, the control system of the game machine 1 will be described with reference to FIG. The game machine 1 is provided with a game control device 50. The game control device 50 is a computer unit including a peripheral device such as a CPU and an internal memory necessary for its operation. The game control device 50 is connected to the input device 4 including the keyboard unit 5 described above, and to the display device 3, the sound output device 7, and the storage device 51. Various signals necessary for game control are input from the input device 4. The output of the magnetic sensor 31 of the keyboard unit 5 is also input to the game control device 50. The display device 3 displays a game screen according to the image signal output from the game control device 50. The sound output device 7 includes a speaker 6 and a driving circuit thereof, and reproduces sound, musical sound, sound effect, and the like corresponding to the sound signal output from the game control device 50 from the speaker 6.

  The storage device 51 is a storage device using a nonvolatile storage medium such as a magnetic disk or a flash memory, and functions as an external storage device for the CPU of the game control device 50. In the storage device 51, a game program PG and game data DG are recorded. The game control device 50 appropriately reads the game program PG and the game data DG, and executes various processes for causing the user to play a predetermined game. The game realized by the game program PG may be set as appropriate as long as it involves operation of the keyboard unit 5, but here, it is assumed that a music game is executed. The music game is a type of game in which an operation in accordance with predetermined music is instructed to the user, and the user's operation is evaluated by comparing the instructed operation with the actual operation of the user. In the game data DG, music data DG1 for playing a music piece on the game machine 1 and operation instruction data DG2 in which an operation procedure to be instructed to the user is recorded. The song data DG1 includes data for reproducing each of the plurality of songs. In the operation instruction data DG2, information specifying which key 11 should be operated at what time during the reproduction of the music is recorded. The operation instruction data DG2 includes at least one type of data for each music piece. A plurality of types of data having different difficulty levels for one piece of music may be recorded in the operation instruction data DG2. In addition to the above, various types of image data and sound source data are recorded in the game data DG, but these are not shown.

  When the game machine 1 is activated, the game control device 50 executes various initial settings necessary to operate as the game machine 1, and then reads the game program PG from the storage device 51 and executes it. Thus, an environment for executing the music game is set. By executing the game program PG, the game control device 50 includes an operation instruction unit 52, an operation processing unit 53, and an operation evaluation unit 54 as logical devices realized by a combination of computer hardware and a computer program. Generated. The operation instruction unit 52 instructs the user to perform an operation in accordance with the reproduction of the music selected by the game user based on the operation instruction data DG2. The operation processing unit 53 determines which key 11 the user has operated at what timing (timing) according to the output from the keyboard unit 5 of the input device 4. The operation evaluation unit 54 compares the user operation determined by the operation processing unit 53 with the operation procedure described in the operation instruction data DG2, and evaluates the user operation. Various logical devices other than those shown in the drawing are generated in the game control device 50, but illustrations thereof are omitted.

  FIG. 5 shows an example of an operation instruction screen that the operation instruction unit 52 presents to the user through the screen of the display device 3. FIG. 5 illustrates only a part of the keys 11. First, the basic configuration of the operation instruction screen 100 will be described. In the operation instruction screen 100, a plurality of lanes 102 divided by a plurality of dividing lines 101 in the left-right direction are set. The dividing line 101 may be displayed or may not be displayed. The interval of the lanes 102 matches the arrangement interval (pitch) of the keys 11 in the left-right direction in the keyboard unit 5, and the number of the lanes 102 matches the number of keys 11. That is, the lane 102 and the key 11 have a one-to-one correspondence. When viewed from the user, the position of each lane 102 in the left-right direction substantially matches the position of the corresponding key 11 in the left-right direction.

  In the lane 102, a symbol 103 for designating the position of the key 11 to be operated by the user and the time when the operation should be performed is displayed. The symbol 103 is shown as a note-like shape as an example, but is not limited to this and may be in an appropriate shape. The symbol 103 is displayed on the lane 102 corresponding to the key 11 to be operated by the user. That is, the position where the user should perform the operation is specified depending on which lane 102 the symbol 103 is displayed on. However, the symbol 103 may be displayed with a width corresponding to the plurality of lanes 102. For example, the symbol 103 may be displayed so as to overlap with the lane 102 adjacent in the left-right direction with the lane 102 corresponding to the key 11 to be operated by the user as the center. The symbol 103 appears at the upper end portion of the lane 102 at a predetermined time, and gradually descends the lane 102 as indicated by the arrow D as the music playback progresses. The symbol 103 coincides with the reference area 104 at the lower end of the lane 102 when the key 11 is to be operated. Thereby, the time when the key 11 corresponding to the symbol 103 should be operated is designated. In FIG. 5, the symbol 103 overlaps the reference region 104 in the third lane 102 from the left. If the user operates the key 11 corresponding to the lane 102 on which the symbol 103 is displayed at the timing when the symbol 103 overlaps the reference area 104, the key 11 at the position specified by the symbol 103 is changed to the symbol 103. Can be operated at the specified time.

  The time at which the symbol 103 appears at the upper end of the lane 102 is set to a time earlier by a predetermined number of seconds than the operation time to be specified by the symbol 103. As an example, the appearance time is set to a time preceding the operation time by a time length corresponding to two measures of the music. Therefore, if the center of the reference area 104 of the lane 102 is the current time Ta on the game, the operation timing of the symbol 103 positioned at the upper end of the lane 102 arrives at a time Tb that is a predetermined second after the current time. Is shown. The vertical distance from the reference area 104 to each symbol 103 indicates the time difference ΔT from the current time to the operation time specified by each symbol 103.

  The operation instruction unit 52 shown in FIG. 4 determines an operation whose operation time comes between the current time Ta and a time Tb after a predetermined time based on the operation instruction data DG2, and corresponds to the determined operation position. The position of each symbol 103 is calculated so that the symbol 103 is arranged on the lane 102 at a position away from the reference region 104 by a distance corresponding to the time difference ΔT. By repeating such processing according to the drawing cycle of the operation instruction screen 100, an image in which the symbol 103 gradually descends in each lane 102 of the operation instruction screen 100 and reaches the reference region 104 at the operation time is displayed on the display device 3. Displayed above. Thereby, the operation described in the operation instruction data DG2 is sequentially instructed to the user, and the user plays the game by operating the key 11 in accordance with the instruction. The lane 102 does not necessarily have to be linearly extended in the vertical direction. A part or all of the lane 102 may be defined to draw a curve. The moving direction of the symbol 103 is not limited to the vertical direction. The symbol 103 moves from the back to the front of the screen, the symbol 103 moves in the left-right direction of the screen, or the symbol 103 moves toward the reference region 104 while appropriately changing the moving direction in the screen. The display of the operation instruction screen 100 may be controlled. The moving speed of the symbol 103 is not limited to a constant speed, and the speed may be changed as appropriate. The display of the symbol 103 may be controlled so that the moving speed of the symbol 103 differs between the lanes 102. Furthermore, the display of the operation instruction screen 100 may be controlled so that the symbol 103 is fixedly displayed for every appropriate range of the music, for example, every 2 bars, and the reference area 104 moves according to the progress of the music.

  In parallel with this, the operation processing unit 53 determines whether or not each key 11 is operated based on the output of the magnetic sensor 31 of the keyboard unit 5 while the operation instruction unit 52 instructs the user to perform the operation through the above processing. . The operation evaluation unit 54 evaluates the user's play by comparing the actual operation of the user determined by the operation processing unit 53 with the operation described in the operation instruction data DG2. The higher the degree of coincidence between the operation described in the operation instruction data DG2 and the operation actually performed by the user, the higher the user's play is evaluated. The degree of coincidence is determined from the viewpoint of both the position of the operation and the timing of the operation. The degree of coincidence of the operation time is determined by a plurality of stages based on a deviation amount between the operation time specified in the operation instruction data DG2 and the actual operation time. It is done in the same way. On the other hand, the operation position is determined based on whether or not the designated key 11 has been operated correctly.

  In the above game machine 1, if there is a variation in the amount of operation of the key 11 when it is determined that the key 11 has been operated, the key 11 that is likely to react and the key 11 that is less likely to react are mixed. There is a variation between the feeling of operation and the actual reaction of the game machine 1, which may impair the interest of the game, such as the user feeling uncomfortable. Therefore, it is desirable that the operation amount when it is determined that the key 11 is operated is substantially constant regardless of the key 11. However, in the keyboard portion 5, there are mechanical errors such as manufacturing errors and mounting errors between the keys 11. For example, as shown in FIG. 6, even when the magnetic sensor 31 is attached at a substantially constant height, each key 11 is in an unoperated state if the position of the key 11 has an error in the vertical direction. The distance between the magnetic sensor 31 and the magnet 32 may be nonuniform between the keys 11. In this case, the measured value of the magnetic sensor 31 when each key 11 is in an unoperated state varies between the keys 11. Therefore, the relationship between the operation amount of the key 11 and the measurement value output from the magnetic sensor 31 may not necessarily match between the keys 11. Further, the measurement value of the magnetic sensor 31 changes under the influence of the external environment such as ambient temperature, humidity, or magnetic field. The change in the external environment includes the case where the magnetic field changes due to the temperature change of the magnet 32. Therefore, although the distance between the magnetic sensor 31 and the magnet 32 in the unoperated state has not changed, the measurement value output from the magnetic sensor 31 may change due to the influence of the external environment. Therefore, in order to correctly determine whether or not each key 11 has been operated, the influence of the mechanical error of the key 11 or a change in the external environment on the measurement value of the magnetic sensor 31 is compensated for each magnetic sensor 31, and each key 11 Therefore, it is necessary to correctly adjust the correspondence between the operation amount and the measurement value of the magnetic sensor 31.

  Therefore, the operation processing unit 53 compensates for the influence of the mechanical error of the key 11 and the change in the external environment on the measurement value of the magnetic sensor 31 by the following method to suppress or prevent the variation in the operational feeling. . First, the basic method will be described with reference to FIG. FIG. 7 is an example in which an appropriate time length is set as a sampling period, and a change in the measured value of one magnetic sensor 31 in that period is recorded. In the figure, the horizontal axis represents time, and the vertical axis represents the measurement value of the magnetic sensor 31. Further, the waveform of FIG. 7 shows a change in the measured value Va output from the magnetic sensor 31. It is assumed that the distance between the magnetic sensor 31 and the magnet 32 is adjusted as designed.

  In the example of FIG. 7, as the distance between the magnetic sensor 31 and the magnet 32 decreases, the measurement value Va (measurement value actually output) of the magnetic sensor 31 changes to a smaller value. Therefore, it can be estimated that the key 11 is in the unoperated state during the time t1 to t2 when the measured value Va is held at the maximum value Vmax and during the time t5 to t6. Moreover, since the measured value Va is changing between the times t2 and t5 and between the times t6 and t7, it is estimated that the key 11 is pressed. It can be estimated that the key 11 is pushed to the maximum during time t3 to t4 when the measured value becomes the minimum value Vmin. Furthermore, the difference Δdx between the measured value Vmax and the measured value Va at an arbitrary time tx is the amount of change in the measured value accompanying the pressing operation of the key 11, and the amount of change Δdx is from the unoperated state of the key 11. It can be handled as a physical quantity indicating the manipulated variable.

  The measured value Von in FIG. 7 is a measured value to be output from the magnetic sensor 31 when a click feeling of the micro switch unit 42 occurs. In other words, the measured value Von is a measured value that is expected to be output from the magnetic sensor 31 when the internal contact of the micro switch unit 42 is switched. Hereinafter, the measurement value Von may be referred to as a determination value. When the user presses the key 11 until the user feels a click feeling, in order to determine that the key 11 has been pressed, it is only necessary to determine whether or not the measurement value Va has decreased to a determination value Von or less. It will be. Between the times t2 and t5, since the measured value Da is smaller than the determination value Von, it can be determined that the key 11 has been operated. On the other hand, since the measured value Va is larger than the measured value Von between times t6 and t7, it is not determined that the key 11 has been operated.

  However, as described above, the measured value Vmax in the unoperated state varies between the magnetic sensors 31 due to mechanical errors of the key 11 and the like, and accordingly, the measured value Vmax in the unoperated state varies between the magnetic sensors 31. For example, if the measured value of the magnetic sensor 31 when an arbitrary key 11 is in an unoperated state is shifted to a larger value Vmax ′, the change amount Δdx of the measured value of the magnetic sensor 31 is The amount of change is smaller than the amount of change to be measured corresponding to the actual operation amount. Alternatively, the measured value of the magnetic sensor 31 in an unoperated state also changes when the external environment such as temperature, humidity, and magnetic field changes. Therefore, it is not possible to correctly determine whether or not the key 11 is operated by simply comparing the actual measurement value Va with the determination value Von. Such inconvenience can be solved by the following method.

  First, a common reference value is set for the measurement values of all the magnetic sensors 31. As an example, the measurement value Vmax in FIG. 7 is set as a reference value for all the magnetic sensors 31. Next, it is determined for each key 11 that the key 11 is in an unoperated state based on the measured value Va. For example, when the state where the measured value Va of the magnetic sensor 31 is held at the maximum value within the change range (a state where the measured value does not change) continues for a certain period of time, the magnetic sensor 31 is handled. It can be determined that the key 11 to be operated is in an unoperated state. Next, the measurement value Va of the magnetic sensor 31 when the key 11 is in an unoperated state is acquired, and the difference Cd between the measurement value Va and the reference value Vmax is calculated as a compensation value for the measurement value of the magnetic sensor 31. There are positive and negative correction values. For example, in FIG. 7, the measured value increases as the distance between the magnetic sensor 31 and the magnet 32 increases. For example, when the measured value Va when the key 11 is in an unoperated state is greater than the reference value Vmax, the compensation value is Calculated as a positive value. On the other hand, when the measured value Va when the key 11 is not operated is smaller than the reference value Vmax, the compensation value is calculated as a negative value. If the measured value in the unoperated state is Vmax ′ in FIG. 7, the compensation value is + Cd. When determining whether or not the key 11 is operated, the actual measured value Va is subtracted from the value obtained by adding the correction value Cd to the reference value Vmax, thereby obtaining the measured value of the magnetic sensor 31 corresponding to the key 11. A change amount Δdx is calculated. By comparing the amount of change Δdx with a threshold value Δdth, which is the difference between the reference value Vmax and the determination value Von, it is possible to determine whether or not each key 11 has been operated on a constant basis without variation.

  The above method can be explained by applying more specific numerical values as follows. First, the reference value set for all the magnetic sensors 31 is 100, and the measured value of the magnetic sensor 31 when the specific key 11 (hereinafter referred to as the key A) is not operated is 80. The measured value of the magnetic sensor 31 when the other specific key 11 (hereinafter referred to as the key B) is not operated is 110, and the determination value Von when the operation is determined to be 50 is changed. It is assumed that the threshold value Δdth of the amount Δdx is 50. In this case, the compensation value for key A is 80-100 = -20, and the compensation value for key B is 110-100 = + 10. If the measured value of the magnetic sensor 31 when the key A is operated is 40, the change amount Δdx of the measurement value related to the key A is 100−20−40 = 40, and the change amount Δdx is the threshold value Δ It is less than dth = 50. Therefore, it is determined that the key A has not been pressed. On the other hand, if the measurement value of the magnetic sensor 31 when the key B is operated is 60, the change amount Δdx of the measurement value related to the key B is 100 + 10−60 = 50, and the change amount Δdx is the threshold value Δ It is equal to dth = 50. Therefore, it is determined that the key B has been pressed. If the difference between the reference value and the measured values of A and B is compared with a threshold value without using a correction value, the change amount of the key A is 100-40 = 60 and the key A is operated. It is determined that the change amount of the key B is 100−60 = 40, and it is determined that the key B is not operated. Similarly, when the determination value Von = 50 is simply compared with the measured value, an erroneous determination occurs. In the above description, the reference value is set to the measured value Vmax in FIG. 7, but it is sufficient that the reference value is set to a common value among all the magnetic sensors 31, and an appropriate value may be set as the reference value. .

  Next, a specific configuration and control procedure of the operation processing unit 53 for determining whether or not the key 11 is operated will be described with reference to FIGS. As shown in FIG. 8, the operation processing unit 53 is provided with an operation determination unit 60, an unoperated state detection unit 61, and a correction value calculation unit 62 as further logical devices. In FIG. 8, the magnetic sensors 31 provided for each key 11 are shown separately from each other with the subscripts of sensor numbers # 1 to #N. The operation determination unit 60 calculates the change amount Δdx of the measurement value for each magnetic sensor 31 as the operation amount of the key 11 in accordance with the measurement value Va output from each magnetic sensor 31, and the change amount Δdx is as large as the threshold value Δdth. In comparison, the presence or absence of an operation is determined for each key 11. The calculation result of the operation determination unit 60 is provided to the operation evaluation unit 54 and used for evaluation of the user's operation.

  The unoperated state detection unit 61 detects the unoperated state of the key 11 for each key 11 based on the measured value Va output from each magnetic sensor 31, and the measured value Vmax of the magnetic sensor 31 in the unoperated state. 'Is associated with the sensor number and provided to the correction value calculation unit 62. The compensation value calculation unit 62 calculates the compensation value Cd for each magnetic sensor 31 based on the difference between the measured value Vmax ′ of the magnetic sensor 31 when the key 11 is not operated and a predetermined reference value, and the calculation result Is provided to the operation determination unit 60 in association with the sensor number. The operation determination unit 60 holds correction value data DC in which the sensor number of the magnetic sensor 31 and the correction value Cd are recorded in association with each other. The operation determination unit 60 updates the compensation value data DC so that the compensation value Cd provided from the compensation value calculation unit 62 is reflected in the compensation value data DC.

  FIG. 9 shows the procedure of the compensation value update process executed by the operation processing unit 53 to update the compensation value Cd. The process of FIG. 9 is executed at an appropriate time while the game machine 1 is operating. For example, the process of FIG. 9 is executed at least once while a music game is played by the user. Although FIG. 9 shows a processing procedure corresponding to one magnetic sensor 31, the processing of FIG. 9 is executed at least once for the other magnetic sensors 31 during the play of the music game. By performing the process of FIG. 9 during the game play, the position of the key 11 in an unoperated state is shifted during the play, or the temperature around the magnetic sensor 31 and the temperature of the magnet 32 are raised during the play. Even if a mechanical change or an environmental change that affects the measurement value of the magnetic sensor 31 occurs, the influence of the change on the measurement value of the magnetic sensor 31 is excluded, and whether or not the key 11 is operated. Can be determined correctly.

  It should be noted that the processing during the game play may be repeatedly executed at a constant cycle, or the operation instruction data DG2 or the like is designated in advance at a time when the possibility that the key 11 is not operated is relatively high. Then, the process of FIG. 9 may be executed for each magnetic sensor 31 at the designated time. For example, in a music game, there may be a period in which an operation instruction to a user is temporarily suspended in accordance with a musical break such as a break of a measure or a modulation part of a song. When such a period exists, the timing may be designated in advance by the operation instruction data DG2 or the like, and the process of FIG. 9 may be executed in accordance with the designation. In addition, when the game machine 1 is activated, the process of FIG. 9 may be executed on time such as each of a plurality of time zones in a day. If the process of FIG. 9 is executed at the time of startup, the correction value can be updated in accordance with the temperature, humidity, magnetic field, etc. of the day. Moreover, if the process of FIG. 9 is performed in each of a plurality of time zones, the compensation value can be updated in accordance with the temperature change during the day. Furthermore, the process of FIG. 9 may be executed in accordance with the change in air conditioning at the place where the game machine 1 is installed.

  When the process of FIG. 9 is started, first, the measurement value Va within the sampling period is taken into the non-operation state detection unit 61 from the magnetic sensor 31 (step S11). Next, whether or not an unoperated state exists in the waveform of the obtained measurement value Va is determined by the unoperated state detection unit 61 (step S12). This process is performed by examining whether or not a portion where the measured value Va is held at the maximum value for a predetermined time is present in the measured value waveform within the sampling period. If an unoperated state is not detected, the operation processing unit 53 ends the current process. On the other hand, when the non-operating state is detected in step S12, the measured value Vmax ′ in the non-operating state is provided to the correction value calculating unit 62 in association with the sensor number. In the compensation value calculation unit 62, the difference between the given measured value Vmax ′ and the reference value given in advance is calculated as the compensation value Cd (step S13). The reference value is a value set in common for all the magnetic sensors 31 as described above. When the compensation value Cd is calculated, the compensation value Cd is provided to the operation determination unit 60 in association with the sensor number. The operation determination unit 60 updates the correction value data DC so that the correction value Cd corresponding to the sensor number is replaced with the newly provided correction value Cd (step S14). After the processing in step S14, the operation processing unit 53 ends the current processing in FIG.

  FIG. 10 shows a procedure of an operation determination process executed by the operation determination unit 60 in order to determine the presence / absence of an operation for each key 11 using the correction value Cd. The process of FIG. 10 is repeatedly executed at a predetermined cycle while the music game is being played. FIG. 10 shows the procedure of processing corresponding to one key 11, but the processing of FIG. 10 is executed in the same manner for other keys 11.

  When the operation determination process of FIG. 10 is started, the measurement value Va is first read from the magnetic sensor 31 (step S21). Next, the operation amount of the key 11 is calculated by subtracting the actual measurement value Va of the magnetic sensor 31 from the sum of the reference value given in advance and the correction value Cd recorded in the correction value data DC. (Step S22). The operation amount here is a value corresponding to the actual operation amount from the unoperated state of the key 11. When the amount of change is calculated, it is determined whether or not the amount of change is greater than or equal to a threshold value (step S23). In the example of FIG. 7, the change amount corresponds to Vmax′−Va (= Vmax + Cd−Va), and the threshold value corresponds to Δdth. If the amount of change is equal to or greater than the threshold, it is determined that the determination target key 11 has been turned on, that is, pressed (step S24). On the other hand, if the amount of change is less than the threshold value, it is determined that the key 11 is off, that is, it is not pressed (step S25). After the determination in step S24 or S25, the determination result is notified to the operation evaluation unit 54 (step S26). When it is determined to be on, the operation determination unit 60 notifies the operation evaluation unit 54 of information indicating which key 11 has been operated and information for determining when the key 11 has been operated. Thereafter, the operation processing unit 53 ends the process of FIG. The compensation value Cd used in step S22 is the latest compensation value Cd recorded in the compensation value data DC, and the same compensation is performed until the compensation value data DC is updated with a new compensation value Cd. The value Cd is used in step S22.

  In step S22 in FIG. 10, the change amount Δdx of the measured value of the magnetic sensor 31 is calculated as the operation amount of the key 11. However, the actual distance between the magnetic sensor 31 and the magnet 32 and the magnetic sensor 31 are calculated. The coefficient or function that correlates the measured value Va with the measured value Va is obtained in advance, and the change amount Δdx of the measured value may be converted into a distance according to the coefficient or function. In that case, the threshold value in step S23 of FIG. 10 can be set as the distance between the magnetic sensor 31 and the magnet 32 to be determined that the key 11 has been pressed. That is, the operation amount of the pressing operation of the key 11 is not limited to the actual change amount itself of the distance between the magnetic sensor 31 and the magnet 32, but is a concept including various physical quantities correlated with the change amount of the distance. When the above coefficient or function is different for each magnetic sensor 31, it is necessary to set the coefficient or function for each magnetic sensor 31 and convert the change amount Δdx of the measured value into a distance for each magnetic sensor 31. Furthermore, when the above coefficients or functions change according to the external environment such as temperature, humidity, magnetic field, etc., those external environments are acquired by appropriate means, and the coefficient or function itself is adjusted according to the change. It may be corrected. As an external environment acquisition means, an operator who operates the game machine 1 commercially inputs it, acquires it from a site providing information such as temperature on the Internet, or detects it using a detection means such as an air temperature sensor. Appropriate means such as can be adopted. When acquiring external environment, such as temperature, by such means, the process of FIG. 9 may be performed by using the change as a trigger.

  In the above embodiment, the operation determination unit 60 determines whether or not the key 11 is operated, and the operation evaluation unit 54 evaluates the operation based on when which key 11 is operated. Instead of this, or in addition, a temporal change in an operation amount such as a speed at which the key 11 is operated or an acceleration may be considered in the evaluation in the operation evaluation unit 54. For example, as shown in FIG. 11, a speed calculation unit 63 is added to the operation processing unit 53, and the change amount calculated in step S22 of FIG. 10 is provided to the speed calculation unit 63 to differentiate the change amount. Further, the speed of the pressing operation of the key 11 may be further calculated, and the calculation result may be provided to the operation evaluation unit 54. Instead of or in addition to the speed calculation unit 63, an acceleration calculation unit that differentiates the change amount of the push operation twice to calculate the acceleration of the push operation as a time change amount and provides the calculation result to the operation evaluation unit 54. It may be provided. When calculating the acceleration, the operation force of the pushing operation can be obtained. Therefore, it is possible to determine how much the key 11 is pushed and use the determination result for the operation evaluation. Alternatively, it is possible to add a process of reflecting the result of determining the operation force on the sound effect to be pronounced along with the operation.

  In the above embodiment, the non-operation state detection unit 61 functions as an example of the non-operation state detection unit by executing the process of step S12 of FIG. 9, and the compensation value calculation unit 62 executes the process of step S13 of FIG. Thus, the operation determination unit 60 functions as an example of the operation amount calculation unit by executing the process of step S22 of FIG. 10, and the operation determination unit 60 performs step S23 of FIG. It functions as an example of an operation determination unit by executing the processes of S25. The speed calculation unit 63 functions as an example of a temporal change amount calculation unit.

The operation member is not limited to the push-in operation, and a member that is operated in various modes such as a slide operation, a rotation operation, and a lever operation may be provided as the operation member. The sensor for detecting the operation of the operation member is not limited to a magnetic sensor. For example, in the above embodiment, in place of the magnetic sensor 31 and the magnet 32, a non-contact type sensor that can output a measurement value according to the distance to the detection target, such as a proximity sensor or a photoelectric sensor, is appropriately used. Good. In the above embodiment, the magnet as the detection target is provided on the operation member side and the sensor is provided on the base side.

Alternatively, the detection target may be provided on another member that is displaced in conjunction with the operation member, and the sensor may be provided such that the distance changes according to the displacement.

  In the above embodiment, the threshold value for determining whether or not the key 11 is operated is set in common among all the operation members, but the threshold value may be differentiated among a plurality of operation members. For example, there may be a case where a game is changed by intentionally changing the amount of operation to be performed by the user between the operation members, such as requiring a relatively large operation or a relatively small operation with respect to a specific operation member. is there. In such a case, the threshold value may be differentiated between the operation members according to the operation amount to be requested from the user. The present invention is not limited to game machines that play music games, and can be applied to various game machines.
