Description

Foot switch {FOOT SWITCH}

The present invention relates to a mat-type foot switch configured to detect a step operation by stepping on the sole.

Conventionally, the mat type foot switch 100 as shown in FIG. 15 is known. The foot switch 100 detects this step operation by stepping on the sole, and is applied in various fields such as opening and closing of an automatic door, driving operation of various devices, reflection ability inspection device, or operation of a game device. Fig. 15 shows, as an example, what is applied to the dance game apparatus among these.

As shown in FIG. 15A, the foot switch 100 includes the lowermost rear sheet 101, the lower electrode sheet 102 stacked on the rear sheet 101, and the lower electrode sheet 102. A spacer sheet 103 laminated on the upper layer electrode sheet 104 made of an insulating material laminated on the spacer sheet 103, a makeup sheet 105 laminated on the upper electrode sheet 104, and the decorative sheet 105. The mat main body 110 formed of the six-layer structure which consists of the uppermost transparent non-slip sheet 106 laminated | stacked on the ()), and the terminal member 120 attached to one edge part of this mat main body 110 are comprised. The terminal member 120 is for supplying a current from the signal source to each electrode sheet 102, 104.

The lower electrode sheet 102 is formed of, for example, a synthetic resin whose sheet body is non-conductive, and a plurality of lower electrode 102a made of a conductive material is formed at a predetermined position on the upper surface, while the upper electrode sheet ( 104 is a conductive material is laminated on the entire lower surface.

The spacer sheet 103 is formed to be elastically compressible by the expandable synthetic resin, and a plurality of through holes 103a are drilled and provided at a position corresponding to the lower electrode 102a. Since the spacer sheet 103 is sandwiched between the two electrode sheets 102 and 104, the two electrode sheets 102 and 104 are usually insulated from each other.

A sign indicating the position of the switch is printed on the upper surface of the makeup sheet 105, whereby the player can recognize the position of the lower electrode 102a.

15. (b) of FIG. 15 (b) by laminating | stacking such a several sheet and the periphery part is sewn-attach or welding process, and the mat main body 110 is formed, and the terminal member 120 adheres to the edge part of this mat main body 110. Foot switch 100 as shown in is formed.

According to the foot switch 100 of such a structure, the upper electrode sheet is pushed by pressing the position of the lower electrode 102a (part shown by an outline arrow in the example shown in FIG. 15) from the non-slip sheet 106. The spacer sheet 103 is compressed while the 104 is bent convex downward. Therefore, since the upper electrode sheet 104 elastically deforms and contacts the lower electrode 102a through the through hole 103a, the both electrode sheets 102 and 104 become energized so that the mat body 110 is detected by detecting this. Stepped on is recognized.

However, in the foot switch 100 as described above, since the switch portions are repeatedly severely stepped on, the stacked sheets rub against each other to generate static electricity, and the static electricity is stored on each sheet constituting the foot switch. do. This tendency is remarkable in the spacer sheet 103 made of urethane foam. In addition, when the static electricity is stored in the foot switch 100, the switch may not only malfunction, but also there is a problem that an electric shock may occur when the mat main body 110 is touched by hand.

An object of the present invention is to provide a foot switch capable of reliably preventing power storage to a sheet by releasing the generated static electricity to solve the above problems.

The foot switch is formed by stacking a plurality of sheets including a sheet-shaped switch so that a step operation can be detected, wherein the lowermost sheet is formed of a material having a conductive front surface substantially. It is to be done.

According to the present invention, even if static electricity is accumulated on the sheets by repeatedly pressing the foot switches for the foot switch operation, the static electricity generated by the conductive material of the lowermost layer is mounted on the lowermost sheet. It is quickly grounded to the surface and does not accumulate static electricity in the foot switch. Therefore, even if the foot switch is touched by hand at the time of storing, the problem of electrocution to static electricity is surely avoided.

<Embodiment of the invention>

Hereinafter, the present invention will be described in detail with reference to a foot switch as a controller of a dance game machine, which is a kind of entertainment machine. 1 is an exploded perspective view showing an embodiment of a foot switch according to the present invention, Figure 2 is an assembled perspective view thereof. 3 is a cross-sectional view taken along the line A-A of FIG. In Fig. 1, the X-X direction is referred to as the horizontal direction and the Y-Y direction as the vertical direction. In particular, the -X direction is referred to as the left side, the + X direction as the right side, the -Y direction as the rear, and the + Y direction as the front.

First, as shown in FIG. 1, the foot switch 1 has the mat-shaped switch main body 10 by which several sheets are laminated | stacked, and the terminal member 11 attached to the edge part of this switch main body 10. As shown in FIG. ) Is configured. Then, the electrical signal from the signal source is supplied into the switch main body 10 via the terminal member 11, and it is detected whether or not the foot switch 1 is stepped on by the on / off of the switch described later. have.

In this embodiment, the switch main body 10 is set to approximately 840 mm x approximately 940 mm in plan view, whereby the player freely steps on the switch main body 10 to turn on the switch of the foot switch 1. The off operation can be freely performed.

The switch main body 10 includes a lower back sheet 2, a cushion sheet 3 laminated on the back sheet 2, an electrode protective sheet 4 laminated on the cushion sheet 3, and A lower electrode sheet 5 stacked on the electrode protective sheet 4, a spacer sheet 6 stacked on the lower electrode sheet 5, an upper electrode sheet 7 stacked on the spacer sheet 6, and And the eight-layer structure which consists of the several sheets for expansion (plate-shaped object 8) laminated | stacked on this upper electrode sheet 7, and the makeup sheet 9 laminated | stacked on this sheet | seat 8 for expansion.

In this embodiment, the sheet-shaped sheet according to the present invention has a three-layer structure of the lower electrode sheet 5 and the upper electrode sheet 7 and the spacer sheet 6 sandwiched between the upper and lower electrode sheets 7 and 5. Although the switch is formed, the sheet-shaped switch of the present invention may not only have such a three-layer structure, but may be a one-layer structure using a piezoelectric element, for example, to face the upper and lower electrode sheets 7 and 5 via an air layer. It may be a two-layer structure.

In addition, the sheet body of this invention is another sheet except the lower electrode sheet 5 and the upper electrode sheet 7, In this embodiment, the back sheet 2, the cushion sheet 3, and the electrode protective sheet 4 Although the spacer sheet 6, the swelling sheet 8, and the makeup sheet 9 correspond to the sheet | seat body, in this invention, a sheet body may add not only these sheets but also sheet bodies other than these, and may reduce on the contrary.

In the present embodiment, the back sheet 2 is formed by using EVA (ethylene vinyl acetate copolymer) as a base material and evenly mixing carbon black made of fine particles of carbon therein. By mixing carbon black evenly in this way, the back sheet 2 becomes a so-called conductive polymer to which conductivity is imparted. By giving electroconductivity to the back sheet 2, the static electricity generated by stepping strongly on the switch main body 10 to rub each other between each sheet is grounded, and the electrical storage of the static electricity to the switch main body 10 is prevented.

In addition, carbon black is a fine particle of carbon produced by incomplete combustion or thermal decomposition of organic matter, and its particle diameter is very small (10 nm to 500 nm), which is dispersed within the molten synthetic resin to impart conductivity to the synthetic resin. It is suitable as a material to make. In the present embodiment, such carbon black is dispersed in EVA. However, the dispersed synthetic resin is not limited to EVA, and an olefin-based thermoplastic synthetic resin such as polyethylene or polypropylene can be suitably applied.

If it has such a resistance value that is set lower than the resistance value is 1 × 10 ³ Ω per 1m, the addition amount of carbon black so too much, because being the strength of the sheet 2 weaker when Thus, whereas when it exceeds 1 × 10 ⁴ Ω This is because the amount of carbon black added decreases, resulting in poor conductivity and the inability to properly ground static electricity. However, the resistance value is different depending on the member configuration in which carbon black is evenly mixed, and the present invention is not limited to the above value.

Further, evenly mixed with the EVA substrate may be not only carbon black, but also metal powder such as iron powder or aluminum powder may be evenly mixed, or carbon printing may be performed on the front and back surfaces of the sheet.

Incidentally, the pair of fasteners 141 and 142 roughly circle the periphery of the switch body 10 from the point M just to the left of the terminal member 11 in the switch body 10 to the point N just to the right. While the switch main body 10 is opened by operating the member 14 from the M point to the N point, the switch body 10 is opened and operated by operating the N point from the N point to the M point, but instead of doing so, the switch is operated from the N point to the M point. The main body 10 may be opened.

And by opening the switch main body by the operation of the fastener member 14, it becomes possible to expose the opposing surfaces of the lower side sheet 12 and the upper side sheet 13 to the outside of the front surface, and to the cushion seat storage space 15 Desorption operation of the cushion seat 3 becomes easy.

Next, the packing of the foot switch 1 is demonstrated based on FIG. FIG. 8 is a perspective explanatory view for explaining the packing of the foot switch 1, FIG. 8A is a state in which the cushion seat 3 is extracted from the storage space 15 of the switch main body 10, FIG. 8 (b) shows a state in which the extracted cushion sheet 3 and the switch main body 10 after the extraction thereof are folded and loaded in the packaging box B, respectively.

Separated from the seat 12, the cushion seat 3 is extracted from the cushion seat storage space 15 and divided into three (front partition cushion 31, middle partition cushion 32, and rear partition cushion 33). do.

Subsequently, as shown in Fig. 8B, the divided partition cushions 31, 32, and 33 divided are overlapped, and the switch main body 10 from which the cushion sheet 3 is removed is oriented in the vertical direction. Fold three times. In this case, as shown in FIG. 1, between the rear expansion sheet 8d, the left expansion sheet 8a, and the right expansion sheet 8b, the gap 82 spaced apart from each other in the longitudinal direction is formed, and the front side is formed. A similar gap 82 is also formed between the expanded sheet 8c, the left expanded sheet 8a, and the right expanded sheet 8b, and the upper electrode sheet 7 is folded three times in the vertical direction to adjoin the adjacent expanded sheet ( 8) The lower side sheet 12 and the upper side sheet 13 are folded without any interference with each other by this.

Subsequently, by inserting each of the divided cushions 31, 32, 33 stacked on the folded lower side sheet 12 and the upper side sheet 13 in the laminated state, the foot switch 1 is inserted into the packaging box B. Packing is completed.

FIG. 9: is explanatory drawing seen from the cross section for demonstrating the operation | movement of the sheet | seat 8 for expansion. In performing the amusement, as shown in this figure, the foot switch 1 is placed on the floor, and the foot 8 is pushed down through the makeup sheet 9 with the foot sheet 1 attached to the bottom. The switch (current-carrying layer 52 and upper electrode sheet 7 shown in FIG. 1) formed thereon is turned on and detected, while the switch is turned off by removing the foot from the sheet 8 for expansion. By this on / off operation, predetermined entertainment advances.

Since the switch main body 10 is partitioned by a step because the position where the switch is turned on due to the presence of the swelling sheet 8 and the other position is separated by the step, the player recognizes the step as the foot texture. Therefore, it is possible for the player to recognize the on / off without checking the existence position of the switch by bowing his / her head during execution, so that the player can be immersed in the original entertainment operation such as a dance operation. You can enjoy more.

In addition, when the swelling sheet 8 laminated on the upper electrode sheet 7 is covered by the decorative sheet 9, the decorative sheet is disposed between the edge portion of the swelling sheet 8 and the surface of the upper electrode sheet 7. Since the inclined portion 93 formed by (9) is formed, the sole is guided by the inclined portion 93 even when the sole is slid on the switch main body 10 so that the inclined portion 93 is smoothly on the swelling sheet 8. It becomes possible to move. Therefore, problems such as a stepping over the step and falling down can be reliably avoided.

FIG. 10 is a perspective view showing a state immediately before placing the foot switch 1 on the floor F. FIG. As shown in FIG. 10, the back sheet 2 is laminated | stacked on the back surface (namely, lowermost layer) of the foot switch 1. This back sheet 2 is formed by mixing carbon black having conductivity evenly as a base material of a synthetic resin raw material made of EVA, and is in a state of providing conductivity. Therefore, a large number of sheets containing a foam of synthetic resin are laminated, whereby the player makes a steep step on the switch main body 10 which is in a state where static electricity is very likely to occur, whereby the switch main body 10 Even when a high level of static electricity is generated, since the ground F is grounded through the back sheet 2, a high level of static electricity is stored in the switch main body 10, whereby when the foot switch 1 is stored after the end of entertainment, Problems such as electric shock are reliably avoided.

Next, the amusement machine using the foot switch 1 which concerns on this embodiment is demonstrated based on FIGS.

Can be loaded. In addition, although the foot switch 1 is connected to one of the interface circuits 221 and 222 for the controller 202 mentioned later in this game body 201 (FIG. 12), two controllers 202 are connected. When connecting, both of the interface circuits 221 and 222 can be connected to the controller 202. In that case, the foot switch 1 may be connected to another interface (not shown) of the game machine body 201 (FIG. 12).

12 is an internal block diagram showing an example of an entertainment system by the game machine. As shown in this figure, the game machine body 201 includes a CPU 205, a bus 206 composed of an address bus, a data bus, and a control bus connected to the CPU 205, and the bus 206. It has the basic structure which consists of each kind of component mentioned below connected to.

A graphics data generation processor 207 is connected to the CPU 205. The bus 206 also includes an interface circuit 221, a main memory 209, a ROM 210, an expansion circuit 211, a parallel port 212, a serial port 213, a drawing processor 214, and The buffer 216, the voice processing processor 217 and the buffer 218, the decoder 219 and the buffer 220, the interface circuits 221 and 222, and the memories 223 and 224 are connected.

In addition, a television monitor 203 is connected to the drawing processing processor 214, and a speaker 226 is connected to the audio processing processor 217 through an amplifying circuit 225. In addition, a recording medium driver 227 is connected to the decoder 219. The memory 223 and the controller 202 are connected to one interface circuit 221, while the memory 224 and the foot switch 1 are connected to the other interface circuit 221a.

And the entertainment system of the above-mentioned structure changes the form according to a use. That is, the television monitor 203 and the speaker 226 become separate members from the game console main body when the entertainment machine main body 201 is configured for home use, but the configuration shown in FIG. 12 when the entertainment system is configured for business use. The elements are all housed in one casing and are integrated.

When the entertainment system comprises a personal computer or a workstation as a nucleus, the television monitor 203 corresponds to a computer display, and includes a drawing processing processor 214, an audio processing processor 217, and an expansion circuit 211. ) Correspond to a part of the program data recorded on the recording medium 204 or the hardware on the expansion board mounted in the expansion slot of the computer, respectively, and includes an interface circuit 221, a parallel port 212, a serial port 213, and The interface circuit 221 corresponds to the hardware on the expansion board mounted in the expansion slot of the computer. The buffers 216, 218, and 220 correspond to respective areas of the main memory 209 or the expansion memory (not shown).

Next, each component shown in FIG. 12 is demonstrated. The graphics data generation processor 207 fulfills the role of the CPU 203 as a coprocessor. In other words, the processor 207 has a function of performing coordinate transformation or light source calculation, for example, a fixed-point format matrix or vector by parallel processing, and performing two-dimensional or two-dimensional image data supplied from the CPU 203 or the like. Based on the coordinate data of each vertex in the three-dimensional surface, the movement amount data, and the rotation amount data, an address on the display area of the processing target image is obtained, and the process of returning this address data back to the CPU 203 or virtual It plays a role of performing a process of calculating the brightness of the image in accordance with the distance from the light source set to.

The interface circuit 221 functions as an interface for a peripheral device, for example, a pointing device such as a mouse or trackball. The ROM 210 stores program data as an operating system of the entertainment system. Speaking of a personal computer, it corresponds to a basic input output system (BIOS).

The decompression circuit 211 decompresses a compressed image compressed by intra encoding based on a moving picture engineering group (MPEG) for a moving picture or a joint picture engineering group (JPEG) for a still picture. Examples of the decompression processing include decoding processing (decoding of data encoded by Variable Length Code), inverse quantization processing, Inverse Discrete Cosine Transform (IDCT) processing, or reconstruction processing of an intra image.

The drawing process processor 214 performs the drawing process with respect to the buffer 216 based on the drawing command which the CPU 203 outputs.

The buffer 216 consists of a display area and a non-display area. The display area is an area for data development displayed on the display surface of the television monitor 203.

In the present embodiment, the non-display area is used to store texture data, color palette data, etc. in addition to data defining a skeleton, model data defining a polygon, animation data providing motion to the model, and pattern data representing the contents of each animation. will be.

Here, the texture data is two-dimensional image data. The color palette data is data for specifying colors such as texture data. These data are divided from the recording medium 204 once or plural times in accordance with the progress of the game, and are previously recorded in the non-display area of the buffer 216 by the CPU 203.

As a drawing command, there are a drawing command for drawing a three-dimensional image using a polygon, and a drawing command for drawing a normal two-dimensional image. Here, the polygon is a polygonal two-dimensional image, and in this embodiment, a triangle or a rectangle is used.

As a drawing command for drawing a three-dimensional image using polygons, polygon vertex address data on the display area of the buffer 216, texture address data indicating the storage position on the buffer 216 of texture data adhered to the polygon, and texture data. For example, the color palette address data indicating the storage position on the buffer 216 of the color palette data indicating the color and the luminance data indicating the luminance of the texture may be used.

Among these data, the polygon vertex address data on the display area is determined by the graphics data generation processor 207 based on the polygon amount vertex coordinate data on the three-dimensional space from the CPU 203 based on the movement amount data and the rotation amount data of the screen itself. The transformation replaces the polygon vertex coordinate data in two dimensions.

Further, the luminance data is determined based on the distance between the light sources virtually arranged at the position where the graphics vertex coordinate data after the coordinate transformation from the CPU 203 appears.

The polygon vertex address data represents an address on the display area of the buffer 216, and the drawing processing processor 214 texture data corresponding to the range of the display area of the buffer 216 represented by three or four polygon vertex address data. I am going to fill in.

One object consists of multiple polygons. The CPU 203 stores the coordinate data on the three-dimensional space of each polygon in the buffer 216 in association with the vector data which is a corresponding skeleton. When the character is moved on the display surface by the operation of the controller 202, that is, when the movement of the character itself is expressed or when the viewpoint position at which the character is viewed is changed, the following processing is performed.

That is, the CPU 203 obtains the three-dimensional coordinate data of the vertices of each polygon held in the non-display area of the buffer 216 with respect to the graphics data generation processor 207, and the coordinates of the skeleton and the data of the rotation amount thereof. It is to provide movement amount data and rotation amount data of each polygon.

The graphics data generation processor 207 sequentially calculates three-dimensional coordinate data after the movement and rotation of each polygon based on the three-dimensional coordinate data of the vertices of each polygon, and the movement amount data and the rotation amount data of each polygon.

The horizontal and vertical coordinate data of the three-dimensional coordinate data of the polygons thus obtained are supplied to the drawing processing processor 214 as address data on the display area of the buffer 216, that is, polygon vertex address data. .

The drawing processing processor 214 writes the texture data indicated by the texture address data allocated in advance on the triangular or rectangular display area of the buffer 216 represented by the three or four polygon vertex address data. As a result, an object to which texture data is adhered to a plurality of polygons is displayed on the display surface of the television monitor 203.

A drawing command for drawing a normal two-dimensional image indicates color palette address data indicating a storage position on a buffer 216 of color palette data indicating the color of the vertex address data, the texture address data, and the texture data, and the luminance of the texture. It consists of luminance data. Among these data, the vertex address data is coordinated by the graphics data generating processor 207 based on the movement amount data and the rotation amount data from the CPU 203 on the vertex coordinate data on the two-dimensional plane from the CPU 203. Coordinate data obtained.

The speech processing processor 217 writes the ADPCM data read out from the recording medium 204 in the buffer 218 and uses the ADPCM data stored in the buffer 218 as a sound source. The speech processing processor 217 reads the ADPCM data into a clock of, for example, a frequency of 44.1 Hz.

Then, the speech processing processor 217 performs processing such as pitch conversion, noise addition, envelope setting, level setting, reverb addition, and the like, for the ADPCM data read from the buffer 218.

When the audio data read from the recording medium 204 is PCM data such as CD-DA (Compact Disk Digital Audio), the audio data is converted into ADPCM data by the audio processing processor 217.

In addition, processing by program data for PCM data is performed directly on the main memory 209. The PCM data processed on the main memory 209 is supplied to the voice processing processor 217 and converted into ADPCM data, and then output from the speaker 226 as voice after the above-described various processes are performed.

As the recording medium driver 227, for example, a CD-ROM drive, a hard disk drive, an optical disk drive, a flexible disk drive, a silicon disk drive, a cassette media reader, and the like can be given.

As the recording medium 204, a CD-ROM, a hard disk, an optical disk, a flexible disk, a semiconductor memory, etc. are mentioned, for example.

The recording medium driver 227 reads out image, audio, and program data from the recording medium 204 and supplies the read data to the decoder 219. The decoder 219 performs error correction processing by ECC (Error Correction Code) on the reproduction data from the recording medium driver 227, and the data after this processing is stored in the main memory 209 or the audio processing processor 217. ) To supply.

The memories 223 and 224 are configured by, for example, a holder and a card type memory. The card type memory is to hold various parameters of the game, for example, to maintain the state at the end point.

The controller 202 is provided with the foot switch 1 as an operation means which can be operated externally, and the main button is a start button which instructs the CPU 203 to start game program data loaded from the recording medium 204 as a main thing. 202a, a select button 202b for inputting various types of information about game program data loaded by the player from the recording medium 204 into the main memory 209 to the CPU 203, and the player displaying a character on the screen. For example, it has four character direction keys 202c which provide the CPU 203 with a command to move up, down, left, and right. In addition, the controller 202 is provided with four first operation buttons 202d and four second operation buttons 202e, and a predetermined function is given to the entertainment.

It is output to the speaker 226.

In the step position indication data memory 305, a large number of step position indication data corresponding to a rhythm such as the number of beats (for example, four beats and eight beats) are stored in a table format according to the difficulty. In addition to the number of beats, a table for storing the step position indication data is prepared for other rhythms of the same beat, for example, the kind of music of the song, or the number corresponding to each song. In the case of 4 beats, each step position indication data is composed of one set of four time series instructions, and in the case of eight beats, each step position indication data is composed of one set of eight time series instructions. . One set of data is written in each column of the table. In terms of the rhythm, in the case of four beats, for example, all four beats have the same interval and the first two beats are short, and the latter two beats are prepared. It is preferable that a plurality of types of step position indication data having the same level of difficulty are prepared. Then, a table corresponding to the music designated by the music name selection unit 303 is selected, and in this embodiment, one set of data in the selected table is output to the speaker 226.

The deviation amount detection / integrating unit 306 measures the deviation amount, the timing deviation of both in this embodiment with an internal timer, etc., based on the result of the step operation instruction and the actual step operation, and the step position for one set of data. It is to calculate the accumulated deviation amount for the indication data. The rhythm setting unit 307 is set to two before one with respect to the first set data after the third as described later, according to the result of integration from the deviation amount detection / integrating unit 306 with respect to the first step position indicating data. Evaluation is performed to level up or down the set data by one degree, and output the result as a set signal. The setting signal from the rhythm setting unit 307 is also output to the dance setting unit 309.

Have. The dance image of each table is memorized in plurality according to the difficulty. In addition, it is preferable that a plurality of dance images having the same level of difficulty are prepared. The dance setting unit 309 receives a setting signal corresponding to the difficulty from the rhythm setting unit 307 and reads a dance image for the third set of data from the selected table.

The scroll display control section 310 is for causing scroll display to be performed on the display surface of the television monitor 203. The step position indication data for one set of data set by the rhythm setting unit 307 and read out from the step position indication data memory 305 is replaced with image data (hereinafter referred to as step position indication mark) to mark memory 311. Accept temporarily). In the mark memory 311, two pieces of continuous one set of data are written in the scroll display so that the image of the step position indication mark can be displayed on the display surface of the television monitor 203 without interruption on the way. The scroll display control unit 310 sequentially shifts the read address at predetermined time intervals, and causes the step position indicating mark from the mark memory 311 to be written into the buffer 216 (Fig. 12) as a scroll image. In this manner, the step position indication mark scrolled in addition to the non-scrolling dance image is also sequentially transmitted to the buffer 216, and the contents of the buffer 216 are repeated in a cycle of 1/60 second or the like by known display scanning means. On the display surface of the television monitor 203, the step position indication mark is scrolled and displayed on the display surface, and the dance image is displayed in a moving picture as a background image.

In this figure, when the player plays a game on the foot switch 1, the background of the dance image D is displayed. Step position indicating marks M1 to M4 which are scrolled downward from the upper side of the screen at a predetermined speed are sequentially displayed in the order of M1, M4, M2, M3. The stop marks S1 to S4 representing the marks of the lower left and upper right displayed on the lower side of the display surface give timing instructions, and the state in which the scrolled mark M completely overlaps (matches) the stop mark S guides the step operation timing. At the timing at which the mark M completely overlaps the stop mark S, the display luminance or display color of the stop mark S is temporarily changed to indicate the coincidence of the timing.

In this embodiment, the marks M1 to M4 have the left step position 9a for the left arrow, the mark M4 for the right arrow for the right step position 9b, the front step position 9c for the up arrow, and the down arrow for the marks M1. Mark M2 corresponds to the rear step position 9d. In the figure, the difficulty level of the dance image represents a relatively low level.

The step motion monitoring unit 312 detects whether or not the four front step positions 9a to 9d disposed in the foot switch 1 change from off to on. The step operation monitoring unit 312 processes the on-time of the first on-state of the four front step positions 9a to 9d as detection data, and detects the on-state in each foot switch unit so as to be identified. .

Next, the game operation of the entertainment system will be described. First, when the start button 202a of the controller 202 is detected, the music name selection screen is displayed on the screen of the television monitor 203. In this screen, for example, when a song name is displayed vertically and horizontally, and a desired song is selected by stepping on a predetermined key of the controller 202 or game selection positions 9e and 9f of the foot switch 1, the song name selection unit ( 303 reads the performance data corresponding to the selected song name from the performance data memory 304, temporarily stores it in the buffer 218 (FIG. 12) and outputs it to the speaker 226.

When the introductory performance is started, a table having a rhythm of beat number corresponding to the selected song is designated from the step position indicating data memory 305, and the predetermined position of this table as the first two sets of data, for example, While the step position indication data having the intermediate level of difficulty is set, the dance setting unit 309 sets the dance image of the difficulty level according to the difficulty of the set step position indication data and also according to this rhythm.

When the first two sets of data of the step position indication data are set, the television monitor 203 is displayed as the step position indication mark M in the form of superimposing one set of data on the dance image D in the background. The display is scrolled on the display surface 203a. When the scroll display of each step position indication mark starts, the monitoring process by the deviation amount detection / integrating unit 107 is performed. The monitoring process is performed in units of one set of data, and when the monitoring result for the one set of data is sent to the rhythm setting unit 307, the rhythm setting unit 307 performs evaluation based on the monitoring result.

Then, receiving the evaluation result, the next one set of data (that is, the third one set of data based on the evaluation result based on the monitoring result of the first one set of data) is set and the dance corresponding to the set one set data. The setting of the image D is performed. That is, the step position indication mark for one set of data to be evaluated has already scrolled out on the display surface 203a, and on the display surface 203a, the step position indication mark based on the next one set of data is scrolled and displayed. In this case, one set of data set based on the evaluation result is set to be delayed.

Subsequently, determination of whether or not the game has ended, that is, whether or not the predetermined time has elapsed from the start of the game, whether or not the end of the performance of the selected song, or whether or not the predetermined dance evaluation is maintained above an arbitrary level is determined. Is done. If not, the display of the dance image D and the step position indication mark M on the display surface 203a is continued, and the same processing is repeated for each set of data sequentially.

When it is determined that the game is finished, the evaluation result of the player's dance, which is the final content of the rhythm setting unit 307, is displayed on the display surface 203a to notify the player.

Next, the above-described "monitoring process" will be described in more detail. First, the variable i representing the number of beats of one set of data as an initial value is set to 1, and the forward step positions 9a to 9d actually obtained from the step motion monitoring unit 312 with respect to the position indication mark M of the first beat are shown in FIG. 12. The on-signal from is detected, and the ± time shift at the time of actually stepping down is measured as the shift time data with respect to the timing at which the mark M completely overlaps the stop mark S. FIG. In this measurement, the period of one beat is divided and set by ± 1/2 periods in the time direction (the stroke direction of the mark M) based on the stop mark S, and the mark M is completely placed on the stop mark S within this classified period. This is done by indicating the time difference from the detected actually stepped point relative to the overlapped point in time.

Since the time point at which the mark M completely coincides with the stop mark S is obtained calculationally from the period of one beat, detection of the on-signal inputted on the condition of stepping on the corresponding footrest 13 from the step motion monitoring unit 111. Shift time data is obtained from the viewpoint. In addition, when stepping on the wrong front step positions 9a to 9d, it may be regarded as not stepping, or a more severe, for example, negative rating may be given. Alternatively, the number of incorrect step operations may be counted, and when the number reaches a predetermined number of times, the game may be forcibly terminated.

Then, between the timing at which the half cycle is shifted and the timing at which both the marks M and S are completely superimposed, for example, converted into 0 to 100 points is shown. For example, when the actual step operation is performed at the time when 1/2 cycle is shifted in any of the ± directions, 0 points are 100 points when the actual step operation is performed at the time when both marks M and S are completely overlapped.

When the score conversion of the deviation time data with respect to the mark M for one beat is completed, the variable i is subsequently incremented by one, and it is determined whether the variable i is less than the predetermined number K. The predetermined number K is set in correspondence with the number of beats of the table selected by the step position indicating data memory 305 when the value 5 is set when the set data consists of four beats, and the value 9 is set when the set data consists of eight beats. . At present, if the variable i is less than 5 as one set of data in four beats, the process returns to step ST33 and a score is obtained as described above for the next mark M. FIG.

When the variable i becomes 5, since the score of 4 beats is obtained, a scoring process for multiplying each score in the variables i = 1 to 4 by multiplying the center point coefficient to obtain evaluation for one set of data is performed. For example, the second and fourth beats have a difficult rhythm compared to the first and third beats, so the center coefficient is 12.5% for their scores for the first and third beats. The team scores a score of 100 points by multiplying 25% for the first and 50% for the fourth. In addition, what is necessary is just to allocate suitably the center coefficient in the case of forming one set of data by 8 beats so that it may be 100% in total. In addition, the midpoint coefficient may be set to a desired value, or the coefficient may be set to 25% (4 beats) or 12.5% (8 beats) uniformly.

Next, the said "evaluation process" is demonstrated in detail. Regarding the score obtained as a result of the monitoring process, one of large, medium, and small is judged. The score is when the score is 80-100, the middle is when the score is 21-79 and the small is when the score is 0-20.

If the score is 20 points, one set of data to be set next is set as the difficulty level down by one level for the current level, and the dance image D to be set in the subsequent degree is one degree for the current level. The down one is set. If the score is 21 to 79, the difficulty level of the same grade as this grade is set as one set of data to be set next, and the dance image D to be subsequently set also has the same difficulty level as this grade. In the table of the step position indication data and the table of the dance image D, plural types are stored for the same difficulty level, and different types of data may be set as much as possible in the data setting of the same class. For example, it is good to change in the direction of difficulty within the range of the data of the same grade, or to set at random within the same grade. On the contrary, if the score is 80 to 100 points, one set of data to be set next is set up by one degree of difficulty with respect to the current grade, and the dance image D to be subsequently set also has a difficulty of 1 for this grade. The grade up is set.

When the setting process of next step position indication data and dance image is complete | finished, this time point is converted into an evaluation point and integrated in the evaluation point up to the last.
