Description

  The present invention relates to a foot motion support system that supports a foot motion in which an athlete goes up and down one step at a time on a flat surface such as a floor, a musical tone generator used in the system, and a program for foot motion support processing , And a music distribution method for distributing an accompaniment music of a stepping motion.

  In the modern automobile society, many people are suffering from chronic lack of exercise. For this reason, there are membership-based exercise facilities such as sports gyms and fitness clubs in various places. However, even if you pay a monthly membership fee and become a member of an athletic facility, it is difficult to go on a daily basis for work convenience or private use, and there are many people who unsubscribe on the way. On the other hand, instead of paying a monthly fee, various exercise devices for maintaining health and enhancing physical strength that can be easily used at home have been proposed. Such home exercise equipment can be used at a time convenient for the user, so it can be used even when the return is late for work or private use, or even in bad weather conditions such as heavy snow or typhoons. There is an advantage that it can be used without any problems.

  Many home exercise devices have been proposed to train legs. This is due to the fact that modern lack of exercise is mainly due to not using the foot, and that the foot is a particularly important part of the body as it is said to be the second heart. This is considered to be due to such reasons. In fact, many experts have stated that training their legs can prevent adult diseases such as diabetes. For example, in response to the question “why exercise improves diabetes”, exercise also helps to eliminate obesity and improves the function of insulin. Specifically, there are the following exercise effects. “Insulin sensitivity is improved”, “Glucose is used to save insulin by exercising”, “Insulin functions become active”, “Insulin increases”, “Good cholesterol (HDL) increases” ”Lipids are easily metabolized” (see Non-Patent Document 1).

  In addition, another expert describes that adults such as diabetes can be prevented by training their feet, stating that “walking is a recommended exercise for all”, regardless of gender. The advantage of being easy to adjust is described. In addition, it is stated that the length of walking time is about 30 to 40 minutes. In addition, the energy consumption (kcal) of walking fast per minute for 1 kg of body weight is “0.0747” at 80 m / min, “0.0906” at 90 m / min, “0.1083” at 100 m / min. , “0.1384” for jogging (light) and “0.1561” for jogging (strong) are described. According to this data, the energy consumption is larger when running than walking (see Non-Patent Document 2).

  On the other hand, there is a view that running consumes muscles and bones. According to Mr. Masanari Suzuki, professor of physical education at the University of Tsukuba, the training method is wrong for both professionals and amateurs in Japan. The most important thing is the “resistive exercise” that trains muscles against the load. Running is a representative of “consumable exercise” and has the advantage of increasing endurance, but it also consumes muscles, bones and body fat. “Resistance exercise” is the opposite, and it means that muscles and bones are grown (see Non-Patent Document 3).

In one proposed foot-type training device, a pair of pedals for placing the left and right feet is provided, and the swing angle and gradient of the pedal itself can be selected according to the stepping motion. (See Patent Document 1).
Similarly, in a proposed stepping exercise machine, a pair of pedals on which the left and right feet are placed are provided, and the impact applied to the legs is reduced by a smooth lifting operation, and the operation is easy. (See Patent Document 2)
Furthermore, in a proposed exercise apparatus, four pressing portions each including a foot switch are provided, and when the user jumps and lands on one of the pressing portions, the landing is detected by the foot switch. In addition, the device connected to the foot switch is provided with a 7-segment light-emitting diode that indicates whether or not the instructed pressing portion and the landing pressing portion coincide with each other. Yes. Therefore, the user can quantitatively grasp the improvement in agility and can strengthen the muscles by jumping. (See Patent Document 3)
However, in the foot-operated training device of Patent Document 1 and the foot-operated exercise machine of Patent Document 2, the pedal tilts as the foot is depressed, and a large load is applied to the foot by the oil damper. Moreover, since the exercise apparatus of the said patent document 3 jumps and lands on a press part, very high exercise capability is requested | required. For this reason, there is no problem for a user who is good at exercising or a young user who has physical strength, but it cannot be easily exercised by an elderly person or a user who does not have physical strength.

  By the way, considering the descriptions of Non-Patent Documents 1 to 3, it can be seen that the combination of “walking exercise” and “resistance exercise” is the optimum exercise. As one form of exercise, an exercise of climbing up stairs can be considered. However, since this exercise is quite hard, even a person with physical strength cannot easily do it. In addition, there are risks for children and the elderly. What anyone, including children and the elderly, can easily do is not only to climb up the stairs, but to step up and down one step. In addition to the stairs, for example, a stepping motion to ascend and descend a threshold or a wooden box may be used. The stepping motion that goes up and down on a sill or a wooden box is a much easier exercise than the one that climbs up and down the stairs continuously. It can be easily performed by people without physical fitness, and even if performed by children and the elderly There is no danger.

  For example, in a proposed stepping exercise apparatus, a load measuring unit is provided inside a pair of left and right footrest plates, and the load measuring unit and the display unit are connected by a cable. Then, the foot order setting unit of the display unit sets the number of times of foot order due to alternate left and right stepping or left and right alternating load change due to continuous one foot, and when the load change does not reach the set foot order number, Or issue a warning by sound. (See Patent Document 4)

On the other hand, this kind of stepping exercise can be done easily, but it is extremely monotonous, so it is difficult to maintain the motivation of the athlete. You will feel mental pain. As a countermeasure, if you perform this stepping exercise while listening to music, video and other things in parallel, you will be able to continue the exercise without feeling mental distress.
For example, in a proposed exercise support method and audio data recording medium for exercise support, the platform is moved up and down while listening to music such as rhythm sounds and musical sounds played by a general playback system such as a household radio cassette player or CD player. Do exercise. In addition, a plurality of music selected on the basis of the exercise intensity related to the height of the platform and the tempo is recorded on the recording medium to be reproduced. (See Patent Document 5)
Japanese Patent Laid-Open No. 11-276636 JP 2004-8625 A JP 60-58177 A Japanese Patent Laid-Open No. 11-253575 JP 2004-216142 A Ryuichi Akiba “Diabetes heals comfortably” DHC Publishing Co., Ltd., March 2, 1998, p239-240 Hideki Ito “Books read by people with high blood sugar levels” Shufu to Seikatsu Publishing, October 4, 1999, p106-109 Edited by Asahi Shimbun “The medical record for tomorrow, exercise and body 4” Asahi Shimbun, October 24, 1993, 5 editions of Sunday

  However, Patent Document 4 and Patent Document 5 do not take into consideration the particularity of the stepping motion that raises and lowers the step by step. Different from running exercise such as jogging, climbing stairs, and exercise of stepping on the left and right pedals in Patent Document 1 and Patent Document 2, so-called dominant feet are used in stepping exercises using a platform unless otherwise noted. As a result, the walking habits that preceded the movement will be continued, and the entire weight will be applied only to the foot that is put on the platform first. As a result, a load is applied only to the knee and ankle of the preceding foot and the waist on the preceding foot side. The load is proportional to the product of the height of the platform and the weight of the user. For this reason, the foot load must be evenly applied to each foot. The simplest way is to swap out the leading leg for every climb. However, when actually performed, the daily rhythm of alternately moving the left and right feet breaks down, making it difficult to perform a smooth stepping motion. Rather, it is possible to perform a stepping motion that is smoother by changing the left and right of the preceding foot at a certain number of times or every time, and an equal load is applied to both feet. In this case, if the previous foot is replaced while counting one leg at a time, or the previous foot is replaced at regular intervals while watching the clock, the effect of the step-up / down movement while listening to music as in Patent Document 5 is effective. It will be lost.

  In the above-mentioned Patent Document 4, as shown in FIGS. 17, 18 and 19, the left foot and the right foot on the footrest are independently detected, but the preceding foot is detected. It is not configured to do. For example, after a certain amount of up-and-down movement with the right foot leading, after putting the right foot and lowering the right foot without riding the left foot, and then starting the lifting movement with the left foot leading, the right foot leading was switched to the left foot leading. Can't detect that. In addition, even when a left and right alternating stepping motion is performed after performing one foot continuous as shown in FIG. 19, it is not possible to determine whether the preceding foot is left or right.

  In addition, there are humans who do not have physical strength, such as elderly people and children, and there are humans who have physical strength that have been trained through exercise. In addition, physical fitness varies depending on gender. The difference in physical strength in the stepping exercise affects the stepping tempo and the step height. In particular, the optimal stepping tempo varies from person to person, and even the same person varies depending on, for example, the morning time zone, the daytime time zone, and the night time zone. When stepping exercises are performed using the platform while listening to music, the stepping tempo naturally follows the tempo of the music. However, in Patent Document 5, as shown in FIGS. 7 and 8, there are a plurality of types of tempos recorded in the audio data for exercise support, but each tempo has a fixed value. Therefore, it cannot meet the various demands of users. For this reason, for example, as shown in FIG. 10, a plurality of types of recorded audio data for exercise support are prepared. However, this increases the cost associated with the production of various types and responds to various requests of users. Has its limits.

  The present invention has been made to solve such a conventional problem. In the stepping motion using a stepping platform, the monotonicity of the stepping motion is eliminated, and the foot load is equally applied to each foot. At the same time, it aims to support the stepping exercise by providing the optimum stepping tempo for various users including young and old.

  According to the stepping motion support system of the present invention, the musical sound generator used in the system, the stepping motion support processing program, and the music distribution method, the monotonicity of the stepping motion is eliminated in the stepping motion using the step platform. In addition, there is an advantage in that the foot load is equally applied to each foot and that the optimum footstep tempo is provided to various users including young and old.

Hereinafter, a first to third embodiments of a foot exercise support system according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing an external appearance of a stepping motion support system in the first embodiment. In FIG. 1, a step 1 is connected by a USB cable 4 to a USB connector (not shown) of a desktop holder 3 to which a mobile phone 2 is attached. The cellular phone 2 is supplied with electric power from the platform 1 via the USB connector 4 and the desktop holder 3. In this figure, the mobile phone 2 is disposed on the front side of the step 1. In other words, the exerciser performs a stepping exercise of ascending and descending on the step 1 from the side opposite to the side where the mobile phone 2 is disposed.

  The step 1 is placed on a floor surface, and is used by an exerciser to move up and down one foot at a time and perform a stepping exercise. The structure is easy to separate. In the state shown in FIG. 1, since the upper step 11 having a height h1 and the lower step 12 having a height h2 are overlapped, the height from the floor is (h1 + h2). When the lower step 12 is removed, the height from the floor is h1 of the upper step 11 only. Further, when the removed lower step 12 is made adjacent to the upper step 11 and moved up and down from the lower step 12 to the upper step 11, the height is (h1-h2). In the first embodiment, h1 = 15 cm and h2 = 5 cm. As a result, the height of the step 1 can be set to 20 cm, 15 cm, and 10 cm. Therefore, since the exerciser can easily set the optimum height of the step 1 for himself / herself, it is possible to provide the optimum step height for various users including young and old.

  On the upper surface of the upper step 11, a plate 11a for placing the left foot and a plate 11b for placing the right foot are provided. Although not shown in the drawing, each plate is supported by elastic members such as two springs inside. When a foot is put on each of the plate 11a and the plate 11b, pressure is applied to the corresponding elastic member, and the plate 11a and the plate 11b are displaced downward. The amount of displacement varies depending on the elastic force of the elastic member and the weight of the exerciser. This displacement serves as a cushion when stepping on the foot, so the burden on the knee, ankle and waist of the athlete can be reduced.

  Further, two sensors for detecting that the left foot and the right foot are put on are provided in the upper step 11 corresponding to the plate 11a and the plate 11b, respectively. As a sensor, a piezoelectric ceramic element for detecting vibration and pressure, an induction type piezoelectric element composed of a magnet and a coil, a small spring (separate from the elastic member supporting the plate 11a and the plate 11b) and a weight are displaced by vibration. There are optical switches such as a proximity switch and a photoelectric switch that detect by light that the position of the plates 11a and 11b changes due to a load. Some of these sensors can generate electric power by the pressure of the weight of the athlete on the plate 11a and the plate 11b. In the first embodiment and the subsequent second and third embodiments, pressure sensors using piezoelectric ceramic elements are used. Since the generated current generated by the stepping motion is alternating current, a rectifier circuit for converting to direct current is required in the power generation unit. Although not shown in the figure, the upper step 11 is provided with a power switch, a volume knob for adjusting the volume, and a connector for a power cord for connecting to a household 100 volt outlet. .

  A connector 13 of a USB cable 4 connected to the mobile phone 2 is attached to the front side surface of the upper step 11 of the step 1. Hereinafter, a connector (not shown) on the step 1 side that is coupled to the connector 13 of the USB cable 4 is also referred to as a connector 13. On the front side surface of the step 1 having the connector 13, a light emitting diode 14a that emits an infrared ray IRa toward the mobile phone 2 is provided integrally with a lens such as a rod lens at a position corresponding to the plate 11a, and corresponds to the plate 11b. The light emitting diode 14b that emits the infrared ray IRb toward the mobile phone 2 is provided integrally with the lens at the position where it is placed. An input terminal 15 for inputting a stereo musical sound signal is provided near the left end of the same front side surface. On the other hand, on the left side surface of the upper step 11, a speaker 16a for generating a stereo L channel tone is provided. Furthermore, a headphone terminal 17 for outputting a stereo musical sound signal to a headphone device (not shown) is provided on the left side surface. Although not shown in this figure, a speaker (symbol 16b) is provided on the right side surface of the upper step 11 to generate a stereo R channel tone.

On the other hand, the mobile phone 2 has a foldable structure, a sub-display unit 2a that displays a radio wave state, a remaining battery level, a time, an incoming call notification of a telephone and a mail, and a light emission that flashes to notify an incoming mail or a telephone call. A diode 2b, a headphone terminal 2c for outputting a stereo tone signal, a USB connector 2d, an antenna 2e, and a side switch 2f are provided. Further, although not visible in this figure, a protective member for protecting the light emitting part and the light receiving part provided inside the mobile phone 2 for transmitting and receiving infrared rays is provided in the vicinity of the antenna 2e. In the first embodiment, the headphone terminal 2 c is connected to the input terminal 15 of the step 1 by a stereo cable 18. Further, although not shown in the figure, an external power input terminal (reference numeral is 2 g) that receives power supply from the desktop holder 3, a main display section (reference numeral is 2 h), a plurality of switches, data, etc. are processed. A circuit board on which electronic components of the circuit to be mounted are mounted. An upper body having a sub display 2a, a light emitting diode 2b, a main display 2h, etc., and a lower body having a headphone terminal 2c, a USB connector 2d, an antenna 2e, a side switch 2f, a switch group, a circuit board, etc. It can be opened and closed by a hinge.
The USB connector 2d is composed of four terminals. In addition to the data input terminal and the data output terminal, there are two power input terminals for supplying power from the outside. Therefore, a configuration in which power is directly supplied from the step board 1 by the USB connector 13 and the USB cable 4 without using the desktop holder 3 is also possible.

Next, the electrical configurations of the step 1 and the mobile phone 2 will be described.
FIG. 2 is a block diagram showing an internal configuration of the step platform 1. The pressure sensor 101 generates and outputs a left foot detection signal by pressing the left foot on the plate 11a. The pressure sensor 102 generates and outputs a right foot detection signal by pressing the right foot on the plate 11b. The comparator 103 compares the output of the pressure sensor 101 with a predetermined threshold, converts the left foot detection signal generated by the pressure sensor 101 by pressing the left foot into a binary left foot detection signal pulse, and outputs the pulse. The comparator 104 compares the output of the pressure sensor 102 with a threshold value, converts the right foot detection signal generated by the pressure sensor 102 by pressing the right foot into a binary right foot detection signal pulse, and outputs the pulse. The oscillation circuit 105 generates and outputs a constant frequency signal. The frequency dividing circuit 106 divides the frequency signal output from the oscillation circuit 105 to a lower frequency, and outputs two high frequency signals having different constant frequencies f1 and f2.

  The modulation circuit 107 amplitude-modulates and outputs the high-frequency signal having the frequency f1 by the left foot detection signal output from the comparator 103, and amplitude-modulates the high-frequency signal having the frequency f2 by the binary right foot detection signal output from the comparator 104. Output. The IRLED driver 108 outputs the modulated left foot detection signal output from the modulation circuit 107 to the light emitting diode 14a, and emits the infrared ray IRa toward the mobile phone 2 as shown in FIG. The IRLED driver 109 outputs the modulated right foot detection signal output from the modulation circuit 107 to the light emitting diode 14b, and emits the infrared ray IRb toward the mobile phone 2 as shown in FIG. Although such a circuit configuration is inexpensive, it does not conform to the standard protocol of the industry standard organization IrDA (Infrared Data Association), which is standardized as one of the short-range communication systems, and therefore will be described later. On the telephone 2 side, specific signal processing is required after receiving infrared rays. Note that the modulation method is not limited to amplitude modulation. Frequency modulation, phase modulation, etc. may be used. Or the structure which provides the infrared communication part based on the protocol of the standard of IrDA in the step 1 side may be sufficient. In this case, since the mobile phone 2 is provided with an infrared communication unit compliant with the IrDA standard protocol, no specific signal processing is required on the mobile phone 2 side.

  The stereo amplifier 110 amplifies and outputs an analog stereo signal output from the mobile phone 2 via the cable 18 shown in FIG. The switch unit 111 includes a power switch for turning on / off power from a power supply unit, which will be described later, a volume knob for adjusting the amplification factor of the stereo amplifier 110, and other switches. The output changeover switch 112 switches the output destination of the stereo signal output from the stereo amplifier 110. The main amplifier 113 amplifies the stereo signal obtained from the stereo amplifier 110 via the output changeover switch 112 and supplies the amplified signal to the L channel speaker 16a and the R channel speaker 16b. The output changeover switch 112 is a switch that can be switched mechanically or electrically when a stereo cable is connected to the headphone terminal 17 shown in FIG. That is, the state shown in FIG. 2 is a state in which the headphone device is connected to the headphone terminal 17, and the stereo signal obtained from the stereo amplifier 110 is supplied to the headphone device via the output changeover switch 112. Hereinafter, a sound generation system using the stereo amplifier 110, the main amplifier 112, and the left and right speakers 16a and 16b, and a sound generation system using the stereo amplifier 110 and a headphone device (not shown) are referred to as a sound system.

  As described above, the power generation unit 114 generates power according to the pressure of the left foot and the right foot on the plate 11a and the plate 11b in the upper step 11 and outputs a direct current converted by a rectifier circuit (not shown). The rechargeable battery 115 is composed of a detachable secondary battery, and supplies a constant voltage power source to the above-described circuit section in the step 1 and is charged by an external direct current. That is, when charging is performed by a direct current output from the power generation unit 114 and a household 100 volt AC voltage is connected to the input terminal 116, the AC adapter 117 reduces the 100 volt AC voltage to a low voltage. It is converted into a DC voltage and charged by the DC current. Further, as shown in FIG. 1, the charging battery in the mobile phone 2 connected via the USB connector 13 and the USB cable 4 is connected to the power generation unit 114 and an AC adapter 117 when an AC voltage of 100 volts is connected. The battery is charged by a direct current output from.

  The diodes 118, 119, and 120 are for controlling the charging current. In this embodiment, the output voltage of the power generation unit 114, the rated voltage of the rechargeable battery 115, the output voltage of the AC adapter 117, and the rated voltage of the rechargeable battery of the mobile phone 2 are 6.0 volts. Therefore, when the rechargeable battery 115 and the rechargeable battery of the mobile phone 2 are fully charged to 6.0 volts, the voltage difference of about 0.6 volts, which is the voltage drop of the diodes 118, 119, 120, is caused. Charging battery 115 and charging battery of mobile phone 2 are not charged. When the terminal voltage of the rechargeable battery 115 or the rechargeable battery of the mobile phone 2 drops below 5.4 volts due to power consumption, the rechargeable battery is charged. Even if the output voltage of the power generation unit 114 or the AC adapter 117 drops below 5.4 volts for some reason, the current does not flow back to the power generation unit 114 or the AC adapter 117 due to the reverse characteristics of the diodes 118 and 119. .

  FIG. 3 is a block diagram showing an internal configuration of the mobile phone 2. The CPU 201 is composed of an LSI incorporating a DSP (digital signal processor) dedicated to signal processing. A program ROM 203, work RAM 204, switch unit 205, RF block 206, memory 207, main display driver 208, sub display driver 209, speech synthesis memory 210, and interface 211 are connected to the system bus 202 of the CPU 201. The CPU 201 controls the cellular phone 2 by exchanging commands and data with these units.

  The program ROM 203 stores in advance a control program including a stepping exercise support processing program executed by the CPU 201 and initial values. Further, accompaniment music data of the foot motion is stored. The work RAM 204 is provided with an area for temporarily storing data processed by the CPU 201, and a register and flag area necessary for executing a stepping exercise support processing program and other control programs. The switch unit 205 includes a switch group such as a power switch, an off-hook switch, an on-hook switch, a mail switch, a transmission switch, a cursor switch, a decision switch, a numeric / character input switch, and the side switch 2f shown in FIG. . The RF block 206 is a wireless transmission / reception unit for transmitting / receiving calls and mails to / from a public switched telephone network via the antenna 2e, or connecting to various sites via a network such as the Internet for communication. A wireless signal processing unit (not shown) is provided. The memory 207 includes a rewritable nonvolatile memory such as a flash ROM, and has a detachable structure.

  The main display driver 208 is connected to a main display unit 2h composed of an LCD (liquid crystal display) or the like, and displays a menu screen or the like according to the operation of the switch unit 205. In addition, some of the switches described above include those having the same switch and having a plurality of functions according to the state at that time, and in conjunction with the icon switch displayed on the main display unit 2h, Some perform functions. The function of each switch will be described later. The sub display driver 209 is connected to the sub display unit 2a shown in FIG. The sub display unit 2a also notifies the arrival of an incoming call or mail by turning on the backlight, and when a specific menu described later is selected, the selection menu may be displayed. The voice synthesis memory 210 stores various voice message data.

    The input / output port of the CPU 201 includes a microphone 212, a speaker 213, a vibrator 214, an infrared communication unit 215, and data input lines and data output lines from the light emitting diode 2b, the headphone terminal 2c, and the USB connector 2d shown in FIG. It is connected. The microphone 212 transmits a telephone voice, and the speaker 213 receives a telephone voice and issues a call notification when a telephone call is made. Furthermore, the speaker 213, the vibrator 214, and the light emitting diode 2b notify incoming calls and mails by ringer sound, vibration, and blinking, respectively. From the headphone terminal 2c, an analog stereo signal is sent to the headphone device dedicated to the step 1 or the cellular phone 2 via the cable 18 shown in FIG.

  In the case of the communication mode (MODE = 0) which is a normal mode, the infrared communication unit 215 performs data transfer such as a file or an image with a personal computer or another mobile phone according to an IrDA standard protocol, or Control of home appliances is possible. On the other hand, in the case of the stepping exercise mode (MODE = 1) in the first embodiment, demodulation processing and frequency separation processing are performed so that the amplitude-modulated left foot detection signal and right foot detection signal shown in FIG. 2 can be received. Specific signal processing such as On the other hand, as a modification, when performing data transfer according to the IrDA standard protocol on the step 1 side, even if the stepping motion mode (MODE = 1) is received according to the IrDA standard protocol. Good. In any case, as shown in FIG. 1, the two systems of infrared rays IRa and IRb transmitted from the platform 1 are received according to the protocol and converted into electrical signals, and then the two systems of left foot detection signal IRa and right foot detection are detected. The signal IRb is input to the CPU 201.

The rechargeable battery 216 is a secondary battery that is charged by a direct current supplied from the outside. When the power switch is turned on, the rechargeable battery 216 supplies approximately 4 volts of power to each circuit. The interface 211 is a circuit that controls the charging of the rechargeable battery 216. The interface 211 detects whether the external power supply is present and whether the external power supply is the USB connector 2d or the external power input terminal 2g. And a smooth charging operation is controlled by converting an external voltage of about 6 volts to about 4 volts. The diodes 217 and 218 prevent the current from flowing backward from the rechargeable battery 216 when the voltage of the external power supply becomes lower than 4 volts for some reason.
In the USB connector 2d, the data input terminal and the data output terminal other than the power input terminal are connected to the input / output port of the CPU 201, which will be described later in the second embodiment.

  When the normal mode (MODE = 0) is changed to the stepping mode (MODE = 1) due to the start of the stepping motion, the infrared communication unit 215 transmits to the mobile phone 2 from the stepping platform 1 under the control of the CPU 201 as described above. The two infrared rays IRa and IRb are received and demodulated, and sent to the CPU 201 as a left foot detection signal IRa and a right foot detection signal IRb. FIG. 4 is a diagram for explaining the signal processing operation in the CPU 201.

  FIG. 4A shows the hardware of the CPU 201 that processes the left foot detection signal IRa when the left foot is on the plate 11a of the step 1 and the right foot detection signal IRb when the right foot is on the plate 11b of the step 1. It is the figure shown with the circuit of the wear. Actually, this signal processing is executed by software of a stepping exercise support processing program, but in order to make the operation easy to understand, it will be described as signal processing by the circuit of FIG. The left foot detection signal IRa is input to the data terminal D, the reset terminal R, and the clock terminal CK of the flip-flop 302. The right foot detection signal IRb is input to the data terminal D of the flip-flop 302, the reset terminal R, and the clock terminal CK of the flip-flop 301. Although not shown in the figure, the reset terminals R of the flip-flops 301 and 302 are initially at a low level by the power-on reset, and both the flip-flops 301 and 302 are in a reset state.

Next, the operation of this circuit will be described.
For example, when the left foot is preceded and a stepping motion is performed at a predetermined tempo, the left foot detection signal IRa and the right foot detection signal IRb have waveforms shown in FIG. That is, when the left foot rides on the plate 11a, IRa changes from low level to high level, and when the right foot rides on the plate 11b, IRb changes from low level to high level. Next, when the left foot descends from the plate 11a, IRa changes from the high level to the low level, and when the right foot descends from the plate 11b, the IRb changes from the high level to the low level. Accordingly, in the flip-flop 301, when the left foot rides on the plate 11a and the high level left foot detection signal IRa is input to the data terminal D and the reset terminal R, the reset state is released. Next, in response to the rising of the right foot detection signal IRb input to the clock terminal CK, the high level left foot detection signal IRa input to the data terminal D is latched and output from the output terminal Q of the flip-flop 301. The signal C1 changes from low level to high level. When the left foot is lowered from the plate 11a and the left foot detection signal IRa changes from the high level to the low level, the reset terminal R of the flip-flop 301 changes to the low level. The output signal C1 from the output terminal Q changes from high level to low level. As a result, the output signal C1 from the output terminal Q of the flip-flop 301 becomes a pulse signal synchronized with the tempo of the stepping motion. In the flip-flop 302, when the left foot detection signal IRa input to the clock terminal CK rises, the right foot detection signal IRb input to the data terminal D is always at a low level. Is not changed from the low level state.

  On the other hand, when the stepping motion is performed with the right foot first, the left foot detection signal IRa and the right foot detection signal IRb have waveforms shown in FIG. That is, when the right foot gets on the plate 11b, IRb changes from low level to high level, and when the left foot gets on the plate 11a, IRa changes from low level to high level. Next, when the right foot descends from the plate 11b, IRb changes from the high level to the low level, and when the left foot descends from the plate 11a, the IRa changes from the high level to the low level. Therefore, in the flip-flop 301, when the right foot detection signal IRb input to the clock terminal CK rises, the left foot detection signal IRa input to the data terminal D is always at a low level. The output signal C1 from the terminal Q does not change from the low level state. In the flip-flop 302, when the right foot gets on the plate 11b and the high-level right foot detection signal IRb is input to the data terminal D and the reset terminal R, the reset state is released. Next, in response to the rise of the left foot detection signal IRa input to the clock terminal CK, the high level right foot detection signal IRb input to the data terminal D is latched and output from the output terminal Q of the flip-flop 302. The signal C2 changes from low level to high level. When the right foot is lowered from the plate 11b and the right foot detection signal IRb changes from the high level to the low level, the reset terminal R of the flip-flop 302 changes from the high level to the low level, so the flip-flop 302 is reset. Thus, the output signal C2 from the output terminal Q changes from the high level to the low level. As a result, the output signal C2 from the output terminal Q of the flip-flop 302 becomes a pulse signal synchronized with the tempo of the stepping motion.

  As described above, according to the circuit of FIG. 4 (1), the number of steps in which the left foot is successively preceded and the right foot is successively preceded by detecting the preceding foot in the stepping motion. The number of steps taken can be easily counted. Further, the tempo of the foot can be detected by the period of the output signals C1 and C2. Furthermore, the total number of steps from the start to the end of the stepping motion can be detected by accumulating the pulses of the output signal C1 and the output signal C2.

Next, the operation of the stepping exercise support system of the first embodiment will be described based on the flowchart of the CPU 201 in the mobile phone 2, the screen of the main display unit 2h, and the like.
5 to 7 are flowcharts of the main routine of the CPU 201 in the mobile phone 2. After predetermined initialization (step SA1), a standby screen is displayed on the main display section 2h (step SA2). Then, it is determined whether or not the value of the flag MODE in the work RAM 204 is 0 (normal mode) (step SA3). If the value of MODE is 0, it is determined whether or not the off-hook switch is turned on (step SA4). When this switch is turned on, a number input screen is displayed on the main display section 2h (step SA5), and the input number is displayed on the main display section 2h in response to the number input from the switch section 205 (step ST5). SA6), the input number is transmitted by operating the transmission switch (step SA7). Then, calling notification is performed by the speaker 213 (step SA8), and it is determined whether or not the line connection with the other party is established (step SA9). When the line connection is established, the ringing tone is stopped and the process proceeds to communication processing (step SA10). During communication, it is determined whether or not the on-hook switch is turned on (step SA11). When this switch is turned on, communication termination processing such as line disconnection is performed (step SA12). Then, the process proceeds to step SA2 to display a standby screen.

  In step SA3, if the off-hook switch is not on, it is determined whether or not the menu switch is turned on in the flowchart of FIG. 6 (step SA18). When this switch is turned on, the main menu screen is displayed (step SA19). FIG. 8 shows the main menu screen. The main menu screen displays a number of menus such as “stepping” and “blood glucose level measurement” in addition to “time / charge” as a call history and “sound / vibe” as an incoming call notification mode. The Then, one menu is focused (step SA20). For example, one menu is highlighted with a frame image or a display color change. The menu to be focused may be the first menu “time / charge” on the screen or the previously selected menu. If “stepping” was previously selected, as shown in FIG. 8, the “stepping” menu is focused and highlighted with a frame image.

  Next, it is determined whether or not the cursor switch is turned on (step SA21). When this switch is turned on, the focus position is moved (step SA22). After the focus position is moved or when the cursor switch is not turned on, it is determined whether or not the determination switch is turned on (step SA23). When this switch is turned on, it is determined whether or not the focus position is “stepping” (step SA24). If it is “stepping”, the stepping menu screen is displayed (step SA25). FIG. 9 shows a step menu screen. On the step menu screen, step menus such as “step setting”, “data input”, and “memory read” are displayed. Then, the foot setting is focused (step SA26). Next, it is determined whether or not the cursor switch is turned on (step SA27). When this switch is turned on, the focus position is moved (step SA28). After the focus position is moved or when the cursor switch is not on, it is determined whether or not the determination switch is turned on (step SA29).

If the menu switch is not on in step SA18, it is determined whether or not another switch is turned on (step SA30). If the other switch is turned on, processing corresponding to the switch is performed (step SA30). SA31). Then, it is determined whether or not the return switch is turned on (step SA32). When this switch is turned on, the process proceeds to step SA2 in FIG. 5 to display a standby screen.
If it is determined in step SA30 that the other switches are not on, the process proceeds to step SA3 in FIG. 5 to determine whether MODE is 0 or not.

  In step SA24 of FIG. 6, when the focus position is not “foot”, it is determined whether or not the focus position is blood glucose level measurement (step SA33a). If it is blood glucose level measurement, blood glucose level measurement processing is executed (step SA33b). If the focus position is not blood glucose level measurement, other menu processing is executed (step SA34a). Then, it is determined whether or not the return switch is turned on (step SA34b). When this switch is turned on, the process proceeds to step SA19 to display the main menu screen.

  When the determination switch is turned on in step SA29 in FIG. 6, it is determined in the flowchart in FIG. 7 whether or not the focus is a foot setting (step SA35). If it is a foot setting, step setting processing is executed (step SA36). If the focus is not the foot setting, it is determined whether or not the focus is data input (step SA37). If the focus is on human data input, data input processing is executed (step SA38). If the focus is not data input, it is determined whether or not the focus is memory reading (step SA40). If the focus is memory reading, memory reading processing is executed (step SA40). If the focus is not memory reading, other processing is executed (step SA41). After the memory reading process or other processes, it is determined whether or not the return switch is turned on (step SA42). When this switch is turned on, the process proceeds to step SA25 in FIG. The step menu screen is displayed.

  FIG. 10 is a flowchart of the foot setting process in step SA36 in FIG. First, the setting item frame screen is displayed on the main display section 2h (step SB1), and the setting contents of the memory 207 are read and displayed on the frame screen (step SB2). 11 (1) to 11 (3) are diagrams showing a foot setting screen. This screen is scrolled by a cursor switch. On the foot setting screen, items of the standard number of times, the step time (minutes), accompaniment music designation, tempo designation, and change notice are displayed. Then, as shown in FIG. 11 (1), the setting contents of the previous setting items read from the memory 207 are displayed. Note that the setting contents shown in FIG. 11 are initially default values transferred from the program ROM 203 to the memory 207, and thereafter are values set in the memory 207 in the previous stepping motion.

  In FIG. 11A, each item is focused according to the set content (step SB3). Initially focus on the reference count. The standard number of times refers to the number of steps approaching this setting value when the left foot or right foot performs a continuous stepping motion while matching the musical tone of the accompaniment, and the number of steps This is a reference value for notifying the exerciser of the timing of changing foot by changing the manner of pronunciation of the accompaniment when the set value is reached. In this case, the left foot (or right foot) rides on the platform 1 first, the right foot (or left foot) then rides on the platform 1, the left foot (or right foot) descends from the platform 1 first, and the right foot (or left foot) continues. The state of getting off the step 1 is defined as one step.

  When changing the previous set value, the set value to be changed is selected by the cursor switch in the focused item. That is, it is determined whether or not the cursor switch is turned on (step SB4). When this switch is turned on, the focus position is moved (step SB5). After the focus position is moved or when the cursor switch is not turned on, it is determined whether or not the determination switch is turned on (step SB6). When the determination switch is turned on, it is determined whether or not the return switch is turned on (step SB7). If the determination switch is not on, or if the return switch is not on, it is determined in step SB4 that the cursor switch is on.

  For example, the previous reference number in FIG. 11 (1) is 25. When the right cursor switch is turned on, as shown in FIG. 11 (2), the numerical value of the previous reference number is focused. A menu screen showing other reference value candidates is displayed in a window. Then, the first candidate “35” is focused. Next, when the down cursor switch is turned on, the focus position moves to the next candidate “30”. When the determination switch is turned on here, the reference number is changed from 25 to 30. After this, the focus position moves to the stepping time.

  When the focus position moves to accompaniment music designation by turning on the cursor switch, a menu screen for selecting accompaniment music candidates is displayed in a window as shown in FIG. Accompaniment music candidates include “user music”, “demo music”, “distributed music”, “rhythm”, and “automatic”. Among them, the demo music, rhythm, and automatic accompaniment music are stored in advance in the program ROM 203 together with the stepping motion support processing program. When a demo song is selected, accompaniment songs of a plurality of genres are displayed in a window as shown in the figure. Here, the rhythm is an accompaniment composed of only a rhythm part such as a drum part, a chord part, a bass part or the like without a melody part, or an accompaniment composed only of a simpler metronome sound. Accompaniment with only rhythm is not musical because there is no melody part. However, for example, when you step on foot while watching TV, the lack of musicality does not interfere with viewing. is there. Automatic is a so-called “automatic accompaniment” that automatically selects and reproduces a plurality of appropriate demo songs according to the setting of the reference number. The user song is digital song data that is uniquely stored in the memory 207 by the user. For example, it is a song in which song data of a CD (compact disc) is stored in the memory 207 via a personal computer or the like. The distribution music is an accompaniment music downloaded from a distribution site and stored in the memory 207 via a network such as the Internet. Therefore, initially, the distribution music is not stored in the memory 207.

  The demo songs, distribution songs, and rhythms, except for the metronome sound, are recorded with PCM recordings of the actual performance songs, and then subjected to unique editing processes that are optimal for supporting the stepping movement. Is the same as the CD song data format, 44.1 kHz sampling, 16 bits / sample per one stereo channel. Therefore, in the case of normal reproduction, about 44100 PCM waveform data are read and reproduced per second. In the first embodiment and the subsequent second and third embodiments of the present invention, irregular reproduction is performed not only for demo songs, distributed songs, and rhythms, but also for user songs, which will be described later. To do.

  When an accompaniment piece is designated on the screen of FIG. 11 (3), an accompaniment piece designation screen is displayed. For example, when a marching song in a demo song is selected by the cursor switch and the decision switch, a list of demo songs stored in the program ROM 203 as an accompaniment song is displayed as shown in FIG. The Then focus on the first march in the list. In this state, the accompaniment is selected by operating the cursor switch. For example, when a certain accompaniment is selected by the down cursor switch and the determination switch is turned on, as shown in FIG. 12 (2), the selected accompaniment is repeatedly played, “one song repeat”, or other One of the playback modes of “other songs and sequence” to be played in order including the accompaniment can be selected.

A switch for returning after the playback mode of one song repeat or another song and a sequence is selected and the decision switch is turned on in step SB6 of the stepping setting process of FIG. 10 to determine the selected playback mode. If is not turned on, the screen returns to the foot setting screen of FIG. When a tempo instruction is selected by the cursor switch, candidates for the tempo of the selected accompaniment are displayed in a window as shown in FIG. That is, candidates that can specify an arbitrary tempo are displayed in addition to a fast tempo of 120 per minute to a slow tempo of 80 per minute. In addition, the focus is on the medium tempo 100 instructed last time. When the determination switch is turned on in this state, if the return switch is not turned on, the step setting screen shown in FIG. 11 is displayed again.
It should be noted that if the sense of tempo is not known until after the foot exercise is started, the tempo instruction may not be given. In this case, as will be described later, the tempo of the selected accompaniment is tentatively set as the foot tempo.

  In the foot setting screen, the selection of ON or OFF for the foot change notification changes the musical tone of the accompaniment when the number of steps approaches or reaches the reference number, as described above. Thus, apart from the method of notifying the exerciser of the change timing, the change timing is notified to the exerciser by a voice message read from the speech synthesis memory 210. For example, "It is time to change foot soon" or "Please change your foot to the right foot first", etc. "Let's step on the floor with the accompaniment before starting to step on the platform" A voice message such as is played. The type of voice message to be played back is not fixed. For example, in data input to be described later, the voice message is determined flexibly in consideration of the age of the entered athlete. Alternatively, when the step tempo is delayed from the set tempo of the accompaniment, a voice message such as “Let's rest a little without overdoing” is reproduced. For this reason, although not shown in the drawing, a process of comparing the set tempo of the accompaniment and the actual foot tempo detected from the pulse signal of FIG. 4 is performed.

In step SB7 of FIG. 10, when the return switch is turned on, it is determined whether or not the setting is changed (step SB8). If the setting is changed, the changed data is stored in the memory 207 and updated (step SB7). Step SB9). After the change data is stored in the memory 207 in step SB8 or when there is no setting change in step SB7, the process returns to the main routine.
In addition to setting the reference number of times, the reference time may be set, or the reference number or the reference time may be selected. In the configuration in which the reference time is set, the clock function of the mobile phone 2 is utilized to execute the timer interrupt when the reference time is approached and when the reference time is reached, and the mode of accompaniment pronunciation Is changed, and the exercise timing is notified to the exerciser. Also in this case, as shown in FIG. 4, the process of discriminating the leading foot by the left foot detection signal IRa and the right foot detection signal IRb obtained from the infrared communication unit 215 is naturally necessary. In addition, about the reference | standard frequency | count or reference | standard time, the structure which sets a different value with a left foot and a right foot may be sufficient. According to this configuration, for example, when the knee or ankle of one foot is injured, the reference number or reference time that the foot precedes is set shorter than the reference number or reference time that the other foot precedes. can do.

  FIG. 13 is a flowchart of the data input process in step SA38 in FIG. First, a data input screen is displayed (step SC1). FIG. 14A shows a data input screen. On this screen, focus on the item of the exerciser ID (step SC2). In addition to the ID, this screen includes items for inputting a password, age, height, weight, stepping time, and step height. Next, it is determined whether or not the cursor switch is turned on (step SC3). When this switch is turned on, the focus position is moved (step SC4). Next, it is determined whether or not data is input (step SC5). When data is input, the input data is displayed (step SC6). Next, it is determined whether or not a password has been input (step SC7). If a password has been input, an asterisk (*) is displayed (step SC8). Next, it is determined whether or not the decision switch is turned on (step SC9). When this switch is turned on, data is stored in the RAM 204 (step SC10). If the determination switch is not on, it is determined whether or not the return switch has been turned on (step SC11). If the switch is not on, the process proceeds to step SC3 to determine whether the cursor switch is on. When the return switch is turned on or after storing data in step SC10, the process returns to the flowchart of FIG.

  After the step setting process in step SA36 in FIG. 7 or the data input process in step SA38, a step execution screen is displayed (step SA43). FIG. 14 (2) is a diagram showing a stepping execution screen. As shown in this figure, among the data set in the foot setting process and the data input in the data input process, data excluding ID, password, and age that do not need to be confirmed is displayed as the foot execution screen. Is displayed. In addition, icon switches of “return switch”, “execution switch”, and “stop switch” are displayed. Then, the execution switch is focused. It should be noted that all foot setting data and input data, including data that is not displayed, are stored in the RAM 204.

  After the stepping execution screen is displayed, it is determined whether or not the execution switch is turned on in the flowchart of FIG. 7 (step SA44). When the execution switch is turned on, MODE is set to 1 (step SA45), and the normal mode is changed to the stepping mode. In this case, since the MODE value is determined to be 1 (stepping mode) in step SA3 in FIG. 5, the accompaniment process (step SA13) is executed. Next, it is determined whether or not infrared rays are received from the platform 1 (step SA14). When the infrared ray is received, count processing (step SA15) is performed, and the process returns to step SA3. Then, as long as MODE = 1, the accompaniment process of step SA13 is executed, and if infrared rays are received in step SA14, the count process of step SA15 is executed.

  If the execution switch is not on in step SA44 in FIG. 7, it is determined whether or not the stop switch is turned on (step SA46). If this switch is not on, whether or not the return switch is turned on in step SA42. However, when the cancel switch is turned on, the process proceeds to step SA2 in FIG. 5 to display a standby screen.

  During the stepping motion, as shown in FIG. 14 (3), the message “Stopping footsteps is displayed when the side switch is turned on” is displayed on the sub display 2a of the mobile phone 2. Is displayed. In this state, the light emitting diode 2b may blink in synchronization with the tempo of the stepping motion. In this state, when infrared rays are not received in step SA14 in FIG. 5, it is determined whether or not the cancel switch 2f is turned on (step SA16a). When this switch is turned on, MODE is reset to 0 (step SA16b). If the stop switch is not on, it is determined whether or not MODE is 1 (step SA17a). If MODE is 1, the process proceeds to step SA13 to perform accompaniment processing. After MODE is reset to 0 in step SA16a, or when MODE is 0 in step SA17a, arithmetic processing is performed (step SA17b). After the calculation process, the process proceeds to step SA2 to display a standby screen.

  If the execution switch is not turned on in step SA44 in FIG. 7, it is determined whether or not the stop switch is turned on (step SA46). When this switch is turned on, that is, the stepping execution in FIG. When the icon stop switch is turned on while the screen is displayed, the process proceeds to step SA2 in FIG. 5 to display the standby screen. If the stop switch is not turned on in step SA46 in FIG. 7, it is determined whether or not the return switch is turned on (step SA42). If this switch is turned on, the process proceeds to step SA25 in FIG. The step menu screen is displayed.

  FIG. 15 is a diagram showing data stored in the RAM 204. In this figure, the data with a slash “/” is the default data before the slash and the data set or input after the slash. Here, NULL indicates that there is no data. Data without a slash is data in which default data remains as it is. For example, the standard number of times is set to 30, the tempo is set to 100, the height is set to 168 cm, the weight is set to 60 kg, and the step height is set to 15 cm, but the stepping time is 1000 minutes, which is practically infinite. . In this case, the exerciser turns on the stop switch and ends the stepping exercise. That is, as described above, when the side switch 2f is turned on in the state in which the stepping stop screen of FIG. 14 (3) is displayed on the sub display unit 2a, the stepping motion is ended. On the other hand, when the stepping time is set to, for example, 30 minutes, the footstep movement automatically ends when 30 minutes have elapsed from the start of the stepping, and the side switch 2f is turned on before 30 minutes have elapsed. Then, the stepping motion ends. In FIG. 15, the left foot count number, the right foot count number, and the MODE value 0 or 1 change during the stepping motion.

  If MODE is 1 in step SA3 of FIG. 5, accompaniment processing is executed (step SA13). FIG. 16 is a flowchart of the accompaniment process. First, it is determined whether or not an execution flag EXF indicating whether or not the foot is executed is 0 (step SD1). That is, it is determined whether or not the stepping motion is not yet being executed (EXF = 0). If EXF is 0, it is determined whether or not a flag ACF for determining accompaniment conditions is 0 (undecided) (step SD2). If the ACF is 0, it is determined whether or not the designated accompaniment is a user song (step SD3a). If it is a user song, it is further determined whether the TEMPO value is NULL and there is no tempo (step SD3a). If there is no tempo, the tempo control is not performed, the normal mode reproduction process other than the foot pedal mode is performed, and the process returns to the main routine of FIG. If it is not a user song in step SD3a, it is determined whether the TEMPO value is NULL and there is no tempo (step SD4a). If the tempo is set, the period of the accompaniment clock based on TEMPO is determined (step SD4b). In step SD4a, if the tempo is not specified, the music data is pre-read to detect the music tempo (step SD5a), and the detected tempo value is stored in TEMPO (step SD5b). In step SD4b, the period of the accompaniment clock based on TEMPO is determined. When the period of the accompaniment clock is determined, for example, when the set tempo is 80, 90, 110, 120, the period of the accompaniment clock to be read is 60 ms, 55 ms, 45 ms, and 40 ms, respectively. Therefore, when the tempo is set, the PCM waveform data read rate is automatically determined according to the period of the accompaniment clock.

  The accompaniment clock is a term and definition uniquely created in the present invention, together with the following accompaniment rhythm, and serves as a trigger for advancing the reproduction of an accompaniment rather than a target of pronunciation. As described above, the demo music stored in the program ROM 203 and the distribution music downloaded from the distribution site to be described later are PCM waveform data of 44.1 kHz sampling and 16 bits / sample per one stereo channel. Yes. In the present invention, in addition to the arrangement of PCM waveform data channels (also referred to as parts or voices) of the accompaniment, an accompaniment clock channel and an arrangement of accompaniment rhythm channels to be sounded are provided. Composition of songs and distribution songs.

  FIG. 17 shows an array of accompaniment songs as a plurality of demo songs stored in the program ROM 203 or a plurality of distribution songs downloaded from the distribution site and stored in the memory 207. Accompaniment data is composed of an accompaniment clock for channel (ch) 1, an accompaniment rhythm for channel 2, a melody for channel 3, and a rhythm for channel 4. The rhythm of channel 4 is actually divided into drum, bass, and chord channels, but here it is assumed to be one channel for the sake of simplicity. In FIG. 17, the portion where the melody and rhythm PCM waveform data is recorded is referred to as the middle portion of the song, and the other portion is referred to as the portion between the songs including the beginning of the first song.

  In FIG. 17, an accompaniment clock is arranged at each address in the inter-music part, and accompaniment rhythm waveform data is arranged for every ten accompaniment clocks. On the other hand, in the middle part of the song, although not shown in detail in this figure, an accompaniment clock is arranged at an address for each of 2205 PCM waveform data, and every ten accompaniment clocks as in the inter-music part Rhythm waveform data is arranged. That is, the accompaniment rhythm waveform data is arranged for every 22050 PCM waveform data. Therefore, since 4100 kHz PCM waveform data of 44.1 kHz sampling and 16 bits / sample is reproduced in one second, 44100 PCM waveform data is reproduced. Also, instead of the PCM waveform data, the accompaniment rhythm waveform data is read and pronounced. Therefore, when the accompaniment rhythm waveform data is sounded, the tone color rhythm sound of the waveform data is generated at two tempos per second for every 22050 non-sounding PCM waveform data.

  By the way, a melody-only song without a rhythm sound is not suitable as an accompaniment piece for a foot movement. Some songs with rhythm sounds are not suitable for stepping. For example, songs such as 3-beat waltz and 5-beat jazz are not suitable for stepping. The music suitable for the stepping movement is 4 beats, and as its genre, the marching music shown in FIG. 12 (1) is suitable, as well as the 4 beats of jazz, pops, tango, samba, song, folk song, A lock is suitable. The tempo is a period from the time signature to the next time signature, and the so-called “hand time” is the tempo. Therefore, the arrangement of the accompaniment rhythm is synchronized with the period of the accompaniment beat. In other words, when the accompaniment shown in FIG. 17 is reproduced, the accompaniment rhythm is synchronized with the period of the volume envelope peak of the musical tone signal of the rhythm of the accompaniment, that is, the period of the PCM waveform data at which the rhythm sound has a maximum value. To do. For this purpose, the PCM waveform data of the performance tune is edited so that the cycle in which the volume of the rhythm of the accompaniment maximal is synchronized with the cycle of the accompaniment rhythm. As a result, even when the accompaniment rhythm is reproduced instead of the accompaniment PCM data at the time of arbitrary reproduction, the period of the rhythm sound to be generated, that is, the tempo is the same.

The reason why such editing is necessary will be described below.
The cycle in which the volume of the rhythm of the actual performance is maximized is not constant, and there is fluctuation in the cycle of the rhythm, so that it has a rich musicality. For example, the “Republic Hymn” of the accompaniment shown in FIG. 12 (1) has four quarters in one measure, that is, four quarters, and the tempo of the song is four minutes per minute. The number of half notes is 88-96. In the performance of Leonard Bernstein and New York Philharmonic recorded on October 20, 1970 about this song, the tempo of the second half is slower than the first half, and subtle fluctuations in the tempo of the whole song There is. For this reason, if an accompaniment piece is created as it is based on the PCM waveform data of the played piece, it is difficult to step on at a constant tempo. Therefore, when creating an accompaniment for the stepping motion, the period at which the volume of the rhythm of the performance is maximized is properly synchronized with every 10 accompaniment clocks at the expense of the musicality of the actual performance. Edit and create as follows. That is, the rhythm of the performance music is quantized so as to synchronize with the accompaniment rhythm of a certain period. It is also possible to create waveform data of musical sounds by software instead of PCM waveform data of actual performance. In this case, first, an accompaniment clock and an accompaniment rhythm array are created, and an accompaniment is created by arranging the period in which the volume of the rhythm in the musical tone waveform data is maximized in synchronization with the accompaniment rhythm.

  As shown in FIG. 17, in the inter-music part, when the accompaniment clock address is an integer of 1 or more, accompaniment is performed for every 10 accompaniment clock addresses such as address 1, address 11, and address 21. There is a rhythm. Here, the portion described as NULL indicates an empty state without data. As a matter of course, the melody of channel 3 and the rhythm of channel 4 are NULL in the portion between songs. The accompaniment rhythm can be, for example, a drum-only, bass-only, timpani-only, triangle-only, tambourine-only simple rhythm tone, or a rhythm tone combining two or more percussion instruments, or a metronome "tack", " The tone is composed of the timbre of “tack”, or the non-musical timbre of “pip”, “pip”, etc., which has a short electronic sound.

  Then, when the first song starts from the position of the dotted line, the first maximum value of the rhythm sound does not come to the song start address. For example, the address of the last accompaniment rhythm in the inter-music portion is (10j + 1). ), 10 accompaniment clocks starting from address (10j + 1) are read out, and the PCM waveform of the first maximum value of the rhythm sound of channel 1 of the first song is synchronized with the accompaniment clock of the next address (10j + 11). Data is arranged. Therefore, the period between the sound generation by the waveform data of the accompaniment rhythm at the address (10j + 1) and the sound generation by the waveform data of the first maximum value of the rhythm sound of the accompaniment coincides with the set tempo period. In the middle part of the song after the song starts, many PCM waveform data consisting of the melody of channel 3 and the rhythm of channel 4 are stored between the accompaniment clock and the next accompaniment clock. In the middle of the song, there is no accompaniment clock at each address, there is an accompaniment clock for every 2205 of PCM waveform data, and there is an accompaniment rhythm for every 10 accompaniment clocks.

  If the address (1000j + 1) is the last maximum value of the rhythm sound of the first song, that is, if the address of the last accompaniment rhythm in the song is (1000j + 1), the song d will be at the address d, which is the end of the subsequent song. END, which is data for identifying the end of the song, is stored in channels 3 and 4, and sound effects having a tone different from the melody and rhythm tone of the entire song and the accompaniment rhythm tone are stored in channel 2. ing. This sound effect is read and output at the timing of changing foot. The sound effect is composed of, for example, a metronome “chain” timbre, or a long electronic timbre “peep”. Therefore, the sound effect at the address d is generated at the changeover timing regardless of the middle part and the inter-song part. However, the sound effect at the address d is not pronounced except when the timing of the end of the song is just the timing of changing. The PCM waveform data from when the melody and rhythm of the address (1000j + 1) is pronounced until the volume of the melody and rhythm sounds of the accompaniment decreases from the maximum value and is muted is read and pronounced. After skipping without sounding and finishing the first song, the accompaniment rhythm at the address (1010j + 1), which is a cycle according to the tempo, is read and pronounced, and thereafter the same as the portion between the songs before the first song In addition, the accompaniment rhythm in the inter-music part is read out and pronounced for every 10 accompaniment clocks in a cycle according to the tempo.

  When the inter-song portion ends and the second song is entered, if the address of the accompaniment rhythm that is pronounced at the end of the inter-song portion is (10k + 1), 2 from the address (10k + 1) regardless of the first address e of the second song The period up to the address (20k + 1) of the PCM waveform data of the first maximum value of the rhythm sound of the song is a cycle corresponding to the set tempo. Therefore, (20k−e) PCM waveform data are read and pronounced from the first address e of the second song to the address before the address (20k + 1). In this way, when a plurality of accompaniments are played in order, the middle part of any accompaniment is played at the tempo at which the maximum value of the rhythm sound, that is, the peak of the volume envelope, is set, and the song ends. Until the next accompaniment starts, the accompaniment rhythm waveform data is sounded at the set tempo, and when the next accompaniment starts, the maximum value of the rhythm sound of that accompaniment is set. It is pronounced at a certain tempo. That is, when the tempo is set, the maximum value of the rhythm sound of the accompaniment or the accompaniment rhythm, or the sound effect at the change timing is generated at the set tempo period corresponding to the tempo period. .

  That is, the arrangement of accompaniment music shown in FIG. 17 is an arrangement of channel 3 and channel 4 that are arrangements of waveform data groups of discrete and sequential accompaniment music composing music including melody sounds and rhythm sounds. For each accompaniment waveform data, a predetermined number of accompaniment clocks and every 10 accompaniment clock channels 1 are synchronized with the waveform data of the accompaniment music, before and after the music (or just before the music). Channel 2 of accompaniment rhythm waveform data composed of a specific tone synchronized with the accompaniment clock, and a tone different from the tone of the accompaniment waveform data group at the end of the song (or may be the beginning of the song) It is composed of channel 3 sound effect waveform data and an array of channel 1 accompaniment clocks synchronized with the sound effect waveform data. Further, the period of the accompaniment rhythm and the period of the musical sound waveform data in which the volume of the rhythm sound of the music is maximized are arranged in synchronization. That is, in the reproduced accompaniment, the maximum value that is the peak of the volume envelope of the rhythm sound is edited so as to be synchronized with every 22050 waveform data.

  In step SD3b of FIG. 16, when the tempo of the user song is designated, the accompaniment clock cycle T is determined according to the tempo (step SD6a). Next, the user song data is prefetched (step SD6b). FIG. 18 is a diagram illustrating a start portion of a user song. In FIG. 18 (1), a1, a2,..., A14... Represent accompaniment rhythms, and represent a period 10T corresponding to 10 accompaniment clocks having a period T of b1, b2,. Based on the volume envelope of the pre-read song data, a rhythm pattern that can be synchronized with the accompaniment rhythm period 10T is searched. Specifically, a predetermined number of peaks in the volume envelope of the rhythm sound in which the rhythm sound has the maximum value in the song data is detected, and the number of waveform data between adjacent peaks is averaged to determine the number of waveform data An average value Wa is calculated. Then, the reading rate tr is calculated by 10 T / Wa (step SD7). As a result, as shown in FIG. 18 (2), if the time t1 from the timing of the first rhythm of the music data to the start time ts of the music data is detected and the time difference t2 with respect to the period 10T is calculated, t2 The accompaniment clock and accompaniment rhythm can be combined with the waveform data of the user song so that the accompaniment clock a10 is synchronized with the previous timing, and the user song can be reproduced according to the set tempo. In FIG. 18, the accompaniment rhythm in the portion between the music indicated by the solid line is pronounced, and the accompaniment rhythm in the portion in the music indicated by the dotted line is not pronounced.

  After calculating the reading rate in step SD7 of FIG. 16 or determining the period of the accompaniment clock based on TEMPO in step SD4b, the flag ACF for determining the accompaniment condition is set to 1 (step SD8). After ACF is set to 1, it is determined whether or not it is the accompaniment readout timing (step SD9). When it is not the read timing, the process returns to the main routine, and when the accompaniment process is entered again, since ACF is 1, the process proceeds from step SD2 to step SD9 to determine whether it is the read timing. When the read timing is reached, it is determined whether or not the read data is the start of music (step SD10). If it is the start of music, the first address of the part between music is specified (step SD11). If it is not the start of the song, the accompaniment clock is read (step SD12), and it is determined whether there is an accompaniment rhythm (step SD13). If there is an accompaniment rhythm, a sound generation process for outputting the accompaniment rhythm is performed (step SD14). After the sound generation process or when there is no accompaniment rhythm in step SD13, the process returns to the main routine of FIG. 5 and proceeds to step SA14.

  Therefore, if EXF is 0 in step SD1 and no stepping motion has been performed yet, the accompaniment clock is repeatedly read out at the determined read rate to generate the accompaniment rhythm. For example, in the case of FIG. 17, accompaniment clocks are read in order from address 1, and accompaniment rhythm is pronounced at address 1, address 11, address 21... Address (10j + 1). Then, it returns to address 1 and repeats the accompaniment rhythm. The pronunciation of such accompaniment rhythm is the same in the portion between the first song and the second song. However, in this case, since the stepping motion is started, the inter-music portion is not repeated, and when the inter-music portion is completed, the second music playback is started.

  When the process moves from the accompaniment process to step SA14 in FIG. 5, it is determined whether or not infrared rays are received from the step 1 (step SA14). When the infrared ray is received, the count process is executed (step SA15). FIG. 19 is a flowchart of the counting process. First, a signal determination process for determining a signal obtained from the infrared communication unit 215 is performed (step SE1). That is, as shown in FIG. 4, a signal determination process is performed to determine whether an LC indicating that the left foot is ahead or an RC indicating that the right foot is ahead is received. It is determined whether or not an LC has been received (step SE2). When an LC is received, the left foot count number of FIG. 15 for storing the left foot leading count value is incremented by one (step SE3). Further, the total number of steps TN is incremented by one (step SE4). Then, it is determined whether or not the value of LC has reached the value obtained by subtracting the value of Δ from the reference number N (step SE5). The value of Δ is 5, for example. Therefore, as shown in FIG. 15, when the value of the reference number N is 30, it is determined whether or not the LC value has reached 25. In step SE2, if LC is not received, it is determined whether or not RC is received (step SE6). When RC is received, LC which is the left foot count number of FIG. 15 storing the left foot leading count value is incremented by one (step SE7). Further, TN is incremented by 1 (step SE8). Then, it is determined whether or not the value of RC has reached the value obtained by subtracting the value of Δ from the reference number N (step SE9).

  If the LC value has not reached the reference number N-Δ in step SE5, or if the RC value has not reached the reference number N-Δ in step SE9, is EXF 0? It is determined whether or not (step SE12). That is, it is determined whether or not the first foot of the step is on the step 1. If EXF is 0, EXF is set to 1 (step SE13). Then, the process returns to the main routine of FIG. 5 through step SE21 and step SE24 (these processes will be described later).

  In the main routine of FIG. 5, the process proceeds from step SA3 to step SA13 and the accompaniment process of FIG. 16 is performed. It discriminate | determines (step SD15). When the time of TIME has not elapsed, for example, when the time of TIME is 1000 minutes as a default in FIG. 15, TIME does not elapse until it exceeds 16 hours and 40 minutes. Therefore, the time is virtually infinite, and the stepping time does not pass TIME. In this case, it is determined whether or not the song is in the middle (step SD16).

  The middle of the song is a period from the start of the song to the end of the song, and in FIG. 17, it is a period from the start of the song indicated by the dotted line to the address d where END is in channel 3 and channel 4. If it is not in the middle of the music, that is, if it is an inter-music part before the music starts, it is determined whether or not it is a read timing for reading the accompaniment clock (step SD23). If it is not the read timing, the process returns to the main routine, but if it is the read timing, the accompaniment clock is read (step SD24), and if there is an accompaniment rhythm, a sound generation process is performed to output the accompaniment rhythm (step SD25). . When the start address of the music is reached, the melody of channel 3 and the rhythm of channel 4 are read, and the sound of the accompaniment rhythm is switched to the sound of the accompaniment music.

  In the middle part of the song after the song starts, as described above, a large number of PCM waveform data consisting of melody and rhythm is stored between the accompaniment clock and the next accompaniment clock. Since the waveform data is 44.1 kHz / sec, 2205 melody and rhythm PCM waveform data are read from any accompaniment clock to the next accompaniment clock. Therefore, the read rate period from any PCM waveform data to the next PCM waveform data is about 22.7 μs. In the figure, the OR portion indicates that there are addresses where accompaniment clocks and accompaniment rhythms are stored and NULL addresses that are not recorded.

  In the counting process of FIG. 19, when LC or RC is received and the register LC or RC of the RAM 204 is incremented and TN is incremented, if the value of the register LC or RC does not reach N−Δ, step SE12 In step SE21 and step SE24, the process returns to the main routine of FIG. 5 and proceeds from step SA3 to step SA15. Therefore, in the accompaniment process of FIG. 16, since the music has started, it is determined in step SD16 that the music is in the middle, and it is determined whether or not CHF is 1 (step SD17). At this time, since the value of the register LC or RC does not reach N−Δ, CHF is 0. Therefore, in step SD23, it is determined whether or not it is the reading timing. If it is the reading timing, the PCM waveform data is read (step SD24), and the accompaniment melody and rhythm are pronounced (step SD25). Then, returning to the main routine of FIG. 5, the process proceeds from step SA14 to the count process of step SA15.

  In the counting process of FIG. 19, when LC or RC is received, the register LC or RC of the RAM 204 is incremented, and TN is incremented, the value of the register LC or RC reaches N−Δ. It is determined whether or not a flag CHF indicating a notice of changing the foot to be performed is 0 (step SE10). If CHF is 0, CHHF is set to 1 (step SE11). Thereafter, EXF = 1 is determined in step SE12, and the process returns to the main routine of FIG. 5 through steps SE21 and SE24, and the process proceeds from step SA3 to step SA13.

  In this case, in the accompaniment process of FIG. 16, since CHF is determined to be 1 in step SD17, a change notice accompaniment process is performed (step SD18). In this change notice accompaniment process, if there is no tempo in step SD3b, that is, unless the user song is normally played without tempo control and without tempo control, the address of the accompaniment clock with the next accompaniment rhythm is reached. Then, the melody and rhythm pronunciation of the PCM waveform data at the address is turned off, and the accompaniment rhythm waveform data is read and pronounced. Furthermore, in this sound generation, a musical tone signal of accompaniment rhythm is output to the step 1 so that sound is generated only in the stereo channel on the side opposite to the currently preceding foot. Next, it is determined whether or not the flag JUST indicating the change timing is 1 (step SD19). If JUST is 0, that is, if it is not yet the timing for changing foot, it is determined in step SD23 whether or not it is the read timing. If it is not the read timing, the process returns to the main routine, but at the read timing, the accompaniment rhythm at the current address is read (step SD24) and the sound generation process is performed (step SD25). Then, the process returns to the main routine. Therefore, in the count process, after the value of the register LC or RC reaches N−Δ, when the JUST is 0, the accompaniment rhythm at the current address is read and the sound generation process is repeated.

  In this change notice accompaniment process, as a modification of the embodiment, there is an accompaniment rhythm in a state in which the melody and rhythm pronunciation of the PCM waveform data is turned off while the address is advanced in the same manner as the accompaniment reproduction. The accompaniment rhythm may be generated when the address is reached. After an athlete changes his / her feet, the address at which accompaniment sounding is resumed is determined depending on where the accompaniment sounding is resumed, depending on whether the configuration of the embodiment or the modification is adopted. . In the case of the configuration of the embodiment, pronunciation of the accompaniment is resumed from the time when the change notice is received. In the case of the configuration of the modified example, the address of the accompaniment is advanced from the time when the change notice is received to the time when the change is made, and the pronunciation of the accompaniment is resumed in real time. Since it is thought that which is natural is an exerciser's preference, you may make it the structure which an exerciser can select in the step notification menu of the step setting screen shown in FIG.

  As a result of the step change notice accompaniment process in step SD18, for example, the exerciser performs a stepping exercise with the left foot in advance and the value of the register LC reaches N−Δ. For example, an accompaniment rhythm consisting only of drums and timpani is heard only from the R channel, and it is recognized that the timing for changing foot is approaching. Accordingly, when the reference number is 30, the accompaniment rhythm is heard from the R channel when the step preceding the left foot is 25 times or more.

  In the counting process of FIG. 19, after CHF becomes 1, the process proceeds from step SE10 to step SE14, and it is determined whether or not the value of the register LC or RC has reached the reference number N. When this value reaches the reference number N, a flag JUST for instructing a change of foot is set to 1 (step SE15). Next, it is determined whether or not the right foot (R) or the left foot (L) has been changed by infrared rays from the step 1 (step SE17). If no change is made, the process returns to the main routine of FIG. 5 through steps SE21 and SE24, and the process proceeds from step SA3 to step SA13.

  In this case, in the accompaniment process of FIG. 16, after performing the accompaniment notice accompaniment process of step SD18, it is determined that JUST is 1 in step SD19. At this time, a step change accompaniment process is performed (step SD20). In this change accompaniment process, the address of the sound effect inserted at the end of the song is designated instead of the timbre of the accompaniment rhythm. Next, it is determined whether or not the flag INF for notifying the change by voice message is 1 (voice notification) (step SD21). When INF is 1, voice data stored in the voice synthesis memory 210, for example, voice data such as “Please change to the right foot first” or “Please change to the left foot first” is specified. The voice notification process is performed (step SD22). After the voice notification process, or when the voice notification process is not performed when INF is 0 in step SD21, it is determined whether or not it is the read timing (step SD23). When the period of 10 times the period of the accompaniment clock is reached, that is, at the timing according to the designated tempo, the sound effect is generated (step SD24).

  As a result, for example, after the exerciser performs a stepping exercise with the left foot in advance and the value of the register LC reaches the reference number N, instead of the accompaniment rhythm by the change notice advance accompaniment process, only the stereo R channel is used. Listen to the sound effect and recognize that it is time to change. In this case, a smooth change can be made by stepping on the floor one or several times and then changing to the right foot. Therefore, the pronunciation of the accompaniment rhythm in the step change notice accompaniment processing in step SD18, the step change accompaniment processing in the step change timing of step SD22, and the pronunciation by the PCM waveform data at the address of the maximum value of the rhythm sound of the other accompaniment are as follows: All the sounds are synchronized with the set tempo, and the exerciser always receives the support of the stepping exercise synchronized with the set tempo regardless of whether or not the foot is changed.

  After the sound effect generation process in step SD25, the process returns to the main routine of FIG. 5 and proceeds to the count process. In this case, it is determined in step SE17 of the counting process in FIG. 19 that the right foot (R) or the left foot (L) has been changed. Then, the register LC or RC is cleared to 0 (step SE18), CHF is reset to 0 (step SE19), and JUST is reset to 0 (step SE20). Then, after step SE21 and step SE24, the process returns to the main routine of FIG. 5 and proceeds to accompaniment processing. In this case, the sound of one channel is returned to the sound of the L channel and the R channel. In this case, since CHF is determined to be 0 in step SD17 of the accompaniment process of FIG. 16, the change notice informing process in step SD18 and the change notice process in step SD20 are not performed, and channel 2 of the accompaniment rhythm is set. Switch off, switch on melody channel 3 and rhythm channel 4 to return to the original accompaniment pronunciation.

  When the accompaniment melody is switched to the accompaniment rhythm pronunciation, if the accompaniment rhythm does not exist at the current address, the address is advanced to the position of the accompaniment clock where the accompaniment rhythm exists. For this reason, the address is advanced to the position of a maximum of nine accompaniment clocks. Therefore, 11000 PCM waveform data samples are skipped. However, since it is less than 1 second in time, it is considered that there is no possibility that the exerciser feels uncomfortable. In order to avoid such PCM waveform data skipping, the address of the last accompaniment is temporarily stored in the CPU 201 register and stored when returning from the accompaniment rhythm to the original accompaniment. It is only necessary to read out the address and read out the accompaniment from that address. Also in this case, the change notification in FIG. 11 (1) is performed in the same manner as in the case where the accompaniment is turned off during the change period and the accompaniment is resumed in real time. The configuration may be set by the exerciser.

  By the way, there are cases where the athlete does not change his / her foot even after listening to the sound effect. In this case, the LC or RC value exceeds the reference number N. Accordingly, the value of LC or RC exceeds the value of N in step SE14 of the count process of FIG. In this case, the process proceeds to step SE16 to determine whether the value of LC or RC has not yet reached N + Δ. For example, if the set reference number is 30, it is determined whether the LC or RC value has not yet reached 35. If N + Δ has not been reached, the process returns to the main routine of FIG. 5 through step SE17, step SE21, and step SE24, and proceeds to accompaniment processing. Therefore, in the accompaniment process, the sound effect inserted at the end of the song continues to be generated.

  When the value of LC or RC reaches N + Δ in step SE16 in FIG. 19, JUST is reset to 0 (step SE20), and the process returns to the main routine in FIG. 5 through step SE21 and step SE24. Migrate to In this case, in the accompaniment process of FIG. 16, when the process proceeds from step SD18 to step SD19, JUST is determined to be 0, so that the sound effect is stopped and the sound is returned to the accompaniment rhythm. Therefore, for example, when the reference number is 30, when the value of LC or RC, which is the number of consecutive steps of the left foot leading or right foot leading, reaches 25, the accompaniment melody and rhythm sounds are switched to the accompaniment rhythm. . When the LC or RC value reaches 30, the accompaniment rhythm sound is switched to the sound effect. If the exerciser does not change foot at this time, sound effects will continue to sound until the LC or RC value reaches 35. After the LC or RC value reaches 35, the sound returns to accompaniment rhythm.

  By the way, in the case where the change-accompaniment accompaniment process is being performed and the exerciser makes a quick change before the change timing is reached, the LC or RC value has reached N in step SE14. No, it is determined as NO, and in step SE16, since the value of LC or RC has not yet reached N + Δ, it is determined as YES. Therefore, the process proceeds to step SE17. Accordingly, it is determined in step SE17 that the foot has been changed to the right foot (R) or the left foot (L). As a result, the register LC or RC is cleared to 0 in step SE18, CHF is reset to 0 in step SE19, and JUST is reset to 0 in step SE20. As a result, there is no problem because it becomes the same as in the case of normal change of foot.

  In the embodiment, the timing for switching from the melody and rhythm of the accompaniment to the accompaniment rhythm is the reference number N-Δ, but the value of Δ may be set by the exerciser. Alternatively, the accompaniment rhythm may not be generated, and only a sound effect may be generated at the time of changing foot. In addition, the configuration may be such that the timbre of the accompaniment rhythm and the tone color of the sound effect are set by the athlete. As you become more accustomed to the stepping exercise, you will be able to grasp the timing of changing your foot even if you pronounce a slightly different tone once. Such setting is performed in the change notification menu on the step setting screen shown in FIG. 11 (1), as in the case where the resumption of the accompaniment music is set from above.

  Next, processing when the accompaniment tempo does not match the actual stepping tempo will be described. In step SE21 of the count process of FIG. 19, the value of the variable M is subtracted from the value of TN, which is the total number of steps, and it is determined whether or not the subtraction value has reached 32. The initial value of M is 0. When TN is incremented by 1 from 1 according to the stepping motion, the value of M is 0 at the beginning, so the value of TN-M, which is a subtraction value, is also incremented by 1 from 1. When the value of TN becomes 32 and the subtraction value becomes 32, 32 of TN is stored in M and the value of M is updated from 0 to 32 (step SE22). Next, a tempo adjustment flag ADJ is set to 1 and a variable m is set to 0 (step SE23).

  Next, in the flowchart of FIG. 20, the tempo difference is calculated by subtracting the step tempo value from the set TEMPO value, and the tempo difference is stored in the register A (step SE25). ). The foot tempo value is measured by detecting the rising and falling edges of the left foot detection signal IRa and the right foot detection signal IRb in the foot detection signal shown in FIG. Next, the tempo difference of the register A is added to the register B. The initial value of register B is zero. Then, the value of the variable m is incremented by 1 (step SE27). At this time, it is determined whether or not the value of m has reached 16 (step SE28). If the value of m does not reach 16, the process returns to the main routine of FIG.

  When the main routine shifts again to the counting process of FIG. 19, the value of TN is incremented by one from 32 to 33. Therefore, the value of TN-M is 1, and the process proceeds from step SE21 to step SE24. Since it is determined in step SE24 that ADJ is 1, the process proceeds to step SE25 in FIG. 20 and the loop processing up to step SE28 is repeated.

  When the value of m incremented by the stepping motion by repeating the loop processing reaches 16, the total of the tempo differences for 16 times is stored in the register B. In this case, the value of B is divided by the value of m, that is, 16, and it is determined whether or not the absolute value is larger than 1/20 of TEMPO (step SE29). That is, it is determined whether or not the average absolute value of the tempo difference exceeds 5% of the set tempo. When the difference in tempo exceeds 5%, it is determined that the exerciser does not match the set tempo for some reason, and the set TEMPO value is updated to the exerciser's stepping tempo ( Step SE30).

  Further, it is determined whether or not the value obtained by dividing the value of B by the value of m is greater than one tenth of TEMPO (step SE31). In other words, it is determined whether or not the tempo of the stepping foot of the exerciser is behind 10% of the set tempo. If the tempo delay is more than 10%, it is determined that the athlete is quite tired or unwell, and a warning is sounded by a voice message (step SE32). Is stopped (step SE33), and MODE is reset to 0 (step SE34). If the tempo difference is within 5% in step SE29, the tempo delay is within 10% in step SE31, or after the accompaniment is stopped and MODE is reset to 0 in step SE34, the registers A and B Is cleared to 0 (step SE35), ADJ is reset to 0 (step SE36), and the process returns to the main routine of FIG.

  In this way, every time the number of footsteps has passed, the exerciser's tempo and the set tempo are checked during the 16th footstep period to determine whether or not it is necessary to adjust the tempo or stop the accompaniment. Is determined. Therefore, after an exerciser sets a tempo and starts a stepping exercise, if the tempo does not match his sense of movement, he or she will not stop the stepping exercise unless it is a significant tempo difference. It can be changed to a suitable tempo. Also, if you decide that you are very tired or unwell, you will stop the accompaniment and warn you that you are feeling tired. It is also effective for health management. Furthermore, if healing type music data is stored in the program ROM 203 in advance, the music can be pronounced to relieve the feelings of the exerciser in such a case. The numerical values for 32 times and 16 times are fixed values set in advance by the program, but these numerical values may be changed according to the input age.

  During the stepping exercise, as described above, the step cancellation screen of FIG. 14 (3) is displayed on the sub display unit 2 a of the mobile phone 2. In this state, when the exerciser turns on the side switch 2f of the mobile phone 2, it is determined in step SA16a of the main routine of FIG. 5 that the stop switch has been turned on, MODE is reset to 0 in step SA16b, and step SA17b Shift to the arithmetic processing. Alternatively, in step SD15 of the accompaniment process of FIG. 16, when the time of TIME that is the set footing time has elapsed, MODE is reset to 0 (step SD26), and the accompaniment is stopped (step SD27). Returning to the main routine of FIG. In this case, since MODE is determined to be 0 in step SA17a in FIG. 5, the process proceeds to step SA17b.

FIG. 21 is a flowchart of the calculation process. First, the motion coefficient stored in the program ROM 203 is read (step SF1) and stored in the register k (step SF2). Next, based on the total number of steps of TN, the weight of WT, the height of the HIGH platform converted to meters, and the k coefficient of motion, the calorie consumption C is calculated by the following arithmetic expression and stored in the register C. (Step SF3).
Calorie consumption (kcal) = TN (number of times) * WT (kg) * HIGH (m) * k
Further, based on the weight of the register WT and the height of the HT converted into a meter, a body mass index (BMI) representing the degree of obesity is calculated by the following arithmetic expression (step S146).
BMI (kg / m ² ) = WT (kg) / HT * HT (m ² )
Then, the calorie consumption of C, the total number of footsteps of TN, and the obesity index of BMI are stored in the memory 207 (step SF4) and displayed on the main display section 2h (step SF8). Then, it is determined whether or not the return switch is turned on (step SF9). When this switch is turned on, the process returns to the main routine.

  FIG. 22 is a flowchart of the memory read process in step SA40 in the main flowchart of FIG. First, a data reading screen is displayed on the main display portion 2h (step SH1). FIG. 23 is a diagram showing a data reading screen. In this screen, a selection menu for the previous, date designation, past average, and transition graph is displayed in order to select whether the data to be read is the previous data, the specified date, or the past average. In addition, a frame for entering a password is displayed. Then, the previous menu is focused (step SH2). It is possible to select both the past average and the transition graph.

  Next, it is determined whether or not the cursor switch is turned on (step SH3). When this switch is turned on, the focus position is moved (step SH4). Next, it is determined whether or not a numerical value has been input (step SH5). When the numerical value has been input, the input numerical value is displayed (step SH6). For example, when the date designation is selected, the input year, month and day are displayed, and when the past average or the transition graph is selected, the input designated period is displayed. Further, it is determined whether or not a password has been input (step SH7), and when it is input, an asterisk (*) is displayed (step SH8). Then, it is determined whether or not the determination switch is turned on (step SH9). If the determination switch is not on, the process proceeds to step SH3 to determine whether or not the cursor switch is on.

  When the determination switch is turned on, it is determined whether or not the password is OK (step SH10). If it is not OK, this flow is terminated, but if it is OK, the contents to be displayed are determined. . It is determined whether or not the selected graph is a transition graph (step SH11). If the selected graph is a transition graph, the data is averaged and rounded off during the specified period (step SH12). A bitmap image is created (step SH13). And the data of a transition graph are displayed on the main display part 2h (step SH14). If the transition graph is not selected, it is determined whether or not the selected is a past average (step SH15), and if it is a past average, the data is averaged for a specified period. (Step SH16), the past average data is displayed numerically on the main display section 2h (step SH14). When the past average is not selected, that is, when the previous time or the date designation is selected, the data of the previous time or the designated date is displayed as a numerical value (step SH14). After displaying the data, the process returns to the main routine of FIG.

  FIG. 24 is a diagram illustrating an example of data of a transition graph. In this example, changes in body weight, calorie consumption, BMI, and blood glucose level are displayed in the designated period from January to September 2004. Although not shown in the figure, when the past average is selected, the average value of the weight, calories burned, BMI, and blood glucose level during the specified period is displayed, and when the previous day or date designation is selected. , The weight of the day, calories burned, BMI, and blood glucose level are displayed. Note that the total number of steps in each month may be displayed on this screen.

  FIGS. 25 and 26 are diagrams showing the configuration and operation in the case of performing the blood glucose level measurement process of step SA33b in the main routine of FIG. In FIG. 25, a clip 61 shaped like a clothespin is a plastic device for sandwiching an athlete's earlobe or other part of the body, and can be opened and closed by a rotating shaft 62 at a substantially central position. The clip 61 is urged in a closing direction by a spring 63 provided behind the shaft 62. At the tip of the clip 61, an opening (reference numeral 65a) and an opening 65b are provided at opposing positions in a pair of holding portions 64a and 64b for holding an earlobe or the like. Further, optical fibers 67a and 68b are connected to the holding parts 64a and 64b by optical connectors 66a and 66b, respectively, and an infrared light emitting part and a light receiving part and optical fibers 67a and 67b in the mobile phone 2 are connected by the optical connectors 68a and 68b. Are positioned by mounting angles 69 so as to face each other with a plastic protective member (not shown) interposed therebetween. The mounting angle 69 is made by molding a thin plate-like resin or metal, and is pressed while sandwiching the mobile phone 2 and is positioned by engaging with the antenna 2e through the hole 69a. When the menu for blood glucose level measurement processing is selected, the sub-display unit 2a of the mobile phone 2 performs measurement by turning on the menu display of the blood glucose level measurement and the side switch 2f as shown in FIG. A message to start is displayed.

FIG. 26 (1) is a diagram showing a state where the clip 61 is sandwiched between the ear lobes 7. Moreover, FIG. 26 (2) is a figure which shows the AA cross section of FIG. 25, when the earlobe 7 is pinched | interposed. In FIG. 26 (2), portions 643a and 643b that press the earlobe 7 in the sandwiching portion 64a and the sandwiching portion 64b are made of an elastic member that does not damage the earlobe 7.
In FIG. 26 (2), the optical connector 66a connected to the holding portion 64a is provided with a rod lens 641a that diverges light, and the infrared ray IRd emitted from the light emitting portion of the mobile phone 2 via the optical fiber 67a diverges. Is done. Then, the optical path is refracted by 90 degrees by the prism 642a provided in the holding portion 64a, and enters the earlobe 7 and passes through it. During the passage, light energy is absorbed by the glucose concentration in the blood that changes according to the blood glucose level. For this reason, there is a difference between the light amount of the infrared ray IRd when entering the earlobe 7, that is, the light amount emitted from the light emitting unit and the light amount of the infrared ray IRd after passing through the earlobe 7. The infrared IRd that has passed through the earlobe 7 is refracted by 90 degrees by the prism 642b provided in the other sandwiching portion 64b, and the rod lens that converges the infrared IRd provided in the optical connector 66b connected to the sandwiching portion 64b. Converged. And infrared IRd injects into the light-receiving part of the mobile telephone 2 via the optical fiber 67b.

  Prior to the blood glucose level measurement, the infrared ray IRd emitted from the light emitting part is incident on the clip 61 without the earlobe 7 being sandwiched in advance, and the light receiving part is passed through the rod lens 641a, prism 642a, prism 642b, and rod lens 641b. The amount of light is measured and stored in the memory 207 as a standard value. Then, as described above, the amount of infrared IRd that has passed through the earlobe 7 and entered the light receiving unit is measured and stored in the memory 207 as a measurement value. Therefore, the amount of light absorbed by the glucose concentration in the blood can be measured. If there is a conversion table between the amount of light absorbed and the blood glucose level in the program ROM 203, the measured blood glucose level can be displayed on the main display unit 2h. However, in the embodiment, the measurement result is transmitted to a predetermined medical site, a precise analysis is performed, and an accurate blood glucose level is received from the medical site.

Therefore, it is possible to accurately measure whether or not the blood glucose level has changed as a result of the stepping exercise. Also, as shown in the data of the transition graph of FIG. 24, if the blood glucose level approaches a normal value by the stepping exercise, not only the monotonous stepping exercise will be enjoyed by the accompaniment but also the feet will be trained. There is also an expert opinion that can prevent adult diseases such as diabetes, so that the effect of recognizing that the health has been recovered by specific numerical values can be obtained.
The body part for measuring the glucose concentration in the blood is not limited to the earlobe. Clips such as fingers, inside the wrist, palm or blood vessels on the back of the hand, between the thumb and forefinger of the hand, and around the throat 61 may be any part as long as it is a part that is easily pinched by 61 and has a blood vessel.

  In the embodiment, as shown in FIG. 25, the infrared light emitting part and the light receiving part and the optical fibers 67a and 67b in the mobile phone 2 are sandwiched by a mounting angle 69 with a plastic protective member (not shown) interposed therebetween. Although the position is determined so as to face each other, it is possible to make the protective member openable and closable and to connect the optical connector directly to the infrared light emitting part and the light receiving part. With such a structure, the mounting angle 69 is not necessary, and the optical axis adjustment of the infrared light is easier than the mounting angle 69.

  FIG. 27 is a flowchart of the communication process of step SA10 in the main routine of FIG. It is determined whether or not the user is connected to a distribution site that distributes the accompaniment music (step SJ1). When connected to the distribution site, a request command for distribution music is transmitted (step SJ2). Then, it is determined whether or not a song list such as song name, performer, song number, and fee has been received from the distribution site (step SJ3), and when received, the song list is displayed on the main display section 2h ( Step SJ4). Then, the first song is focused (step SJ5). Next, it is determined whether or not the cursor switch is turned on (step SJ6). When this switch is turned on, the focus position is moved (step SJ7). After the focus position is moved or when the cursor switch is not turned on in step SJ6, it is determined whether or not the determination switch is turned on (step SJ8). When the determination switch is turned on, one or more music lists designated by the focus are stored in the transmission buffer (step SJ9). Then, it is determined whether or not the transmission switch is turned on (step SJ10), and when this switch is turned on, the music list is transmitted to the distribution site (step SJ11). Thereafter, it is determined whether or not song data has been received from the distribution site (step SJ12), and when received, the song data is stored in the memory 207 (step SJ13). Then, the process returns to the main routine.

In step SJ1, if it is not connected to the distribution site, it is determined whether or not it is connected to the medical site (step SJ14). When connected to the medical site, the measurement data is transmitted (step SJ15). The measurement data to be transmitted includes height, weight, calorie consumption, and BMI in addition to the measurement value and standard value of infrared IRd measured with the instrument of FIG. Then, it is determined whether or not blood glucose level data has been received from the medical site (step SJ16), and when received, the received blood glucose level data is stored in the memory 207 (step SJ17). Then, the process returns to the main routine. Actually, since precise analysis at a medical site is necessary, after transmitting measurement data, the line is temporarily disconnected and blood glucose level data is received when an incoming call is received from the medical site. .
If the medical site is not connected in step SJ14, other communication processing is performed (step SJ18). Then, the process returns to the main routine.

  Next, a stepping motion support system according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 28 is a diagram illustrating a connection between a part of the step 1 and the mobile phone 2 in the second embodiment. The same components as those in the first embodiment shown in FIG. As shown in this figure, a holder 19 for mounting the mobile phone 2 is provided on the front side surface of the upper step 11 of the step 1. A USB connector 19a is provided at the lower part of the holder 19, and is configured to be directly inserted into the USB connector (2d in FIG. 1) of the mobile phone 2. When the cellular phone 2 is removed, the two movable pieces 19b of the USB connector 19a are pressed and pulled out as in the general structure. From the light emitting part (not shown) inside the mobile phone 2 attached to the holder 19, the infrared ray IRc is emitted upward through the plastic protective member 2i. In addition, the mobile phone 2 receives not only power supply from the platform 1 but also a left foot detection signal and a right foot detection signal through the USB connector 19a.

  FIG. 29 is a diagram showing the structure of the headphone device 5 that receives the infrared rays from the mobile phone 2 and generates a musical sound. In the headphone device 5, a left speaker 51a and a right speaker 51b are fixed by a support member 52 having elasticity in the left-right direction. Although not shown in the drawing, an adjuster for adjusting the vertical position of each speaker 51a, 51b is provided on the support member 52. In the center of the support member 52, a signal processing unit 53 for processing the PCM waveform data of the accompaniment received from the mobile phone 2 and other data is provided. The signal processing unit 53 is provided with a power switch 53a, an indicator 53b that emits light when the power is turned on, a rechargeable battery 53c that is detachably accommodated, and the like. Further, as shown in FIG. 28, a light receiving unit 54 including a lens and a photodiode is provided below the left speaker 51a in order to receive upward infrared IRc from the mobile phone 2. Further, from the outer surfaces of the left speaker 51a and the right speaker 51b, bars 55a and 55b protrude in front of the left and right sides of the face when the athlete wears the headphone device 5 on the head. Light emitting diodes 56a and 56b that emit visible light such as red and green are provided inside the distal ends of the bars 55a and 55b. These bars 55a and 55b are optional parts for notification of changing foot, and are connected to each speaker 51a and 51b with a connector so as to be detachable. Therefore, a user who does not want to have such bars 55a and 55b next to his / her eyes can be easily removed.

FIG. 30 is a block diagram showing an internal configuration of the signal processing unit 53 in FIG. The CPU 501 is constituted by a one-chip LSI incorporating a signal processing DSP, a program ROM, a work RAM, a D / A converter, and the like. The interface 502 turns on the indicator 53b and supplies power from the rechargeable battery 53c to the circuit of the signal processing unit 5 in response to an ON operation of the power switch 53a. The detachable rechargeable battery 53 c has the same specifications as the detachable rechargeable battery 115 of the step 1 shown in FIG. 2 and can be charged using the step 1. The infrared communication unit 503 receives the infrared IRc from the mobile phone 2 via the light receiving unit 54 by a communication method based on the IrDA protocol or a unique communication method. The amplifier 504 amplifies the analog stereo signal output from the CPU 501 and generates sound from the left and right speakers 51a and 51b. The driver 505 and the driver 506 blink the left and right light emitting diodes 56a and 56b in accordance with the drive signal output from the CPU 501.
Note that the infrared communication unit 503, the amplifier 504, the drivers 505 and 506, and the interface 502 can be incorporated into the CPU 501 and configured as a hybrid IC. In this case, the inside of the signal processing unit 53 can be made extremely light and small.

  Next, the operation will be described. The circuit configuration, signal processing, and other operations of the mobile phone 2 in the second embodiment are almost the same as the operations in the first embodiment. The step 1 is the same as the first embodiment except for a part of the circuit configuration. Therefore, the operation of the second embodiment will be described with appropriate reference to the drawings of the first embodiment. In the second embodiment, as described above, the USB connector 19a receives the left foot detection signal and the right foot detection signal from the step platform 1. Therefore, in the step 1, the left foot detection signal and the right foot detection signal are transmitted by the two terminals of the USB connector 19 a as in the first embodiment, not the USB interface specification by bidirectional communication. Then, the PCM waveform data of the accompaniment, the waveform data of the accompaniment rhythm, and the waveform data of the sound effect are transmitted by the infrared ray IRc emitted upward from the mobile phone 2. The accompaniment clock is used to read out the PCM waveform data of the accompaniment, the waveform data of the accompaniment rhythm, and the waveform data of the sound effect from the program ROM 203 or the memory 207. Therefore, it is not necessary to transmit the accompaniment clock to the headphone device 5.

  In the circuit shown in FIG. 2, the binary left foot detection signal and right foot detection signal pulses are transmitted from the modulation circuit 107, so that the 4-terminal USB connector is used instead of the 2-terminal USB connector 13 shown in FIG. The power supply and the left foot detection signal and the right foot detection signal to the mobile phone 2 are transmitted by 19a. Therefore, the mobile phone 2 receives the left foot detection signal IRa and the right foot detection signal IRb as shown in FIG. However, in the USB interface specification, in order to perform bi-directional data transfer using a two-terminal signal line, data is input from the USB connector 2d (19a in FIG. 28) to the input / output port of the CPU 201 shown in FIG. Line and data output line are connected. Therefore, as shown in FIG. 31, in the CPU 201, the two ports 201a and 201b are switched to the input port or the output port by the control signals STa and STb, respectively. In the stepping mode, both the ports 201a and 201b are set as input ports, and the left foot detection signal and the right foot detection signal are received from the step board 1. However, when the left foot detection signal IRa and the right foot detection signal IRb as shown in FIG. 4 are multiplexed and transmitted on the step 1 side, they can be transmitted to the mobile phone 2 only by the USB data transmission line. Which one to select may be determined according to design cost, manufacturing cost, and the like.

  When the headphone device 5 receives the infrared light carrying the musical tone data of the accompaniment music from the mobile phone 2 by the light receiving unit 54, the infrared communication unit 503 displays the PCM waveform data of the accompaniment music of the stepping motion, the waveform data of the accompaniment rhythm, and the sound effect The waveform data is demodulated and input to the CPU 501. The CPU 501 stores the data input from the infrared communication unit 503 in the work RAM according to the control program in the program ROM. When the stored data is PCM waveform data of accompaniment music, it is converted into stereo musical tone data by the DSP and output to the amplifier 505 as analog L channel and R channel musical tone signals by the D / A converter. On the other hand, if the stored data is accompaniment rhythm or sound effect waveform data, it is converted into one channel L / R channel tone data by the DSP, and the analog L channel / R channel data is converted by the D / A converter. It outputs to the amplifier 505 as a musical sound signal. Further, in synchronization with the received accompaniment rhythm, the light-emitting diode 56b (or 56a) corresponding to the right foot (or left foot) to be preceded instructed by changing foot is blinked with a relatively long cycle (for example, 1 second cycle). The replacement signal is output to the driver 506 (or 505). Further, in synchronization with the received sound effect, the light-emitting diode 56b (or 56a) corresponding to the right foot (or left foot) to be preceded instructed by changing foot is blinked in a short cycle (for example, 0.5 second cycle). The replacement signal is output to the driver 506 (or 505).

As described above, the stepping motion support system according to the second embodiment includes the step 1 for placing on a plane such as the floor and performing the stepping motion, and the mobile phone 2 that outputs the musical tone of the accompaniment for the stepping motion. And a headphone device 5 that receives accompaniment data of the foot movement by infrared rays.
The step platform includes a pressure sensor 101 that generates a left foot detection signal in response to detection of a left foot load applied to the upper plate 11a, and a pressure sensor that generates a right foot detection signal in response to detection of a right foot load applied to the upper plate 11b. 102, and a light emitting diode 14a and a light emitting diode 14b for transmitting the left foot detection signal and the right foot detection signal by infrared rays.
On the other hand, the cellular phone 2 is input from the switch unit 205 and the switch unit 205 that input setting data of the reference number of steps and the tempo of the stepping motion that one of the left foot and the right foot successively precedes according to the operation. RAM 204 for storing setting data, program ROM 203 and memory 207 for storing accompaniment data, infrared communication unit 215 for emitting infrared light to headphone device 5, and the tempo of the foot movement stored in RAM 204 In response, the accompaniment data stored in the program ROM 203 or the memory 207 is read to generate a musical sound, which is transmitted to the headphone device by the infrared communication unit 215 and detected from the step board 1 via the USB connector 19a. The number of consecutive receptions of the signal and the right foot detection signal is stored in the RAM 204. When you reach the number, and a CPU201 for changing the tone of the accompaniment music occurring sound effect.
Therefore, as in the first embodiment, the monotonicity of the stepping motion is canceled by the accompaniment music, and the number of consecutive steps of the preceding foot is notified by the change of the accompaniment music for each reference number. Since the stepping load is equally applied and the accompaniment is generated at the tempo set by the exerciser, the optimum stepping tempo can be achieved for various users including men and women of all ages. Further, since no cable is connected to the headphone device 5, there is no obstacle to the stepping motion.

  Next, a third embodiment of the present invention will be described with reference to FIG. 32 (1) shows that an athlete connects the headphone terminal 2c of the mobile phone 2 housed in a special case 9 fixed to the waist belt 8 and the headphone device 5 with an analog stereo cable 18 to step on the foot. It is a figure which shows a mode that it is exercising. The configuration of the platform 1 is almost the same as that of the first embodiment, but the platform 1 has a Bluetooth communication function, and the left foot detection signal and the right foot detection are detected from the transmitting antenna 20 provided on the front side surface. The signal is transmitted to the mobile phone 2 by a Bluetooth radio signal. Of course, the mobile phone 2 that receives this also has a Bluetooth function. Since Bluetooth is becoming more common as it is already used in mobile phones, detailed explanation is omitted, but data is transmitted and received by frequency hopping spread spectrum short-range wireless communication (LWI). Class 3 covers a transmission range of several meters to 10 meters with a maximum power of 1 mW.

  In the configuration shown in FIG. 32 (1), since the cable 18 is only on the upper body of the exerciser, the stepping exercise is not obstructed. The Bluetooth communication method has not yet become widespread compared to the infrared communication method, but the communication distance is longer than that of the infrared communication method and there is no linear orientation like the infrared communication method. So it is expected as a new near field communication. Therefore, in the near future, it is expected to spread as a general short-range communication of a mobile phone. As a result, if a mobile phone equipped with Bluetooth can be purchased at a low cost, the stepping exercise support system having the configuration shown in FIG. 32A can be realized at low cost.

  32 (2), in the same way as in FIG. 32 (1), the athlete can connect the headphone terminal 2c and the headphone device 5 of the mobile phone 2 accommodated in the special case 9 fixed to the waist belt 8 to the analog case. It is a figure which shows a part in the case of connecting with the cable 18 for stereos and performing a stepping motion. However, the stepping is counted on the step 1 side. The step 1 generates a left foot detection signal in response to detection of a load applied to the upper surface plate 11a, and generates a right foot detection signal in response to detection of a load applied to the upper surface plate 11b. And the reference | standard frequency | count N of stepping is received from the mobile telephone 2 by infrared rays as preset value preset data. When the number of consecutive left foot detection signals or right foot detection signals reaches the reference number N, a foot change signal is transmitted to the mobile phone 2 by infrared IR. However, since the infrared transmission / reception of the cellular phone 2 is performed on the upper side, that is, the antenna 2e side, the cellular phone 2 is accommodated upside down in the special case 9 fixed to the belt 8 as shown in FIG. To do. In this case, a dedicated case 9 corresponding to the protective member 2i of the light receiving unit that receives infrared rays, the headphone terminal 2c, the side switch 2f for starting and stopping the foot, and the sub display unit 2a. An opening is provided in

  In the configuration shown in FIG. 32 (2), as in the case of FIG. 32 (1), since the cable 18 is only on the upper body of the exerciser, the stepping exercise is not obstructed.

  FIG. 33 (9) is a diagram showing an embodiment in which the foot preceding the stepping motion is counted on the step 1 side. In this case, the flip-flop circuit and counter circuit shown in FIG. 4, or a circuit or software having an equivalent function, and a CPU for executing the circuit are provided on the step 1 side. Then, the set reference number N is transmitted from the cellular phone 2 to the platform 1, and a foot change signal EX for generating accompaniment rhythm and sound effects is transmitted from the platform 1 to the cellular phone 2. Therefore, a further modification can be configured by combining the configuration of FIG. 33 (9) and each of FIGS. 33 (1) to 33 (8).

  For example, FIG. 33 (10) shows the count of the foot that precedes the stepping motion on the step 1 side, and shows the mode of the third embodiment shown in FIG. 32 (2). The reference number N is transmitted from the mobile phone 2 to the platform 1 by infrared rays, and the foot change signal EX is transmitted from the platform 1 to the cellular phone 2 by infrared rays. The cellular phone 2 transmits an analog accompaniment to the headphone device 5 via the cable 18 connected to the headphone terminal 2c.

As described above, the stepping motion support system according to the first embodiment of the present invention outputs the musical sound of the accompaniment music for the stepping platform 1 for performing the stepping motion on a flat surface such as a floor. Mobile phone 2 to be provided.
The step 1 is a pressure sensor 101 that generates a left foot detection signal in response to detection of a left foot load applied to the upper plate 11a, and a pressure that generates a right foot detection signal in response to detection of a right foot load applied to the upper plate 11b. The sensor 102 includes a light emitting diode 14a and a light emitting diode 14b that transmit the left foot detection signal and the right foot detection signal with infrared rays.

On the other hand, the mobile phone 2 includes an infrared communication unit 215 that receives the left foot detection signal and the right foot detection signal transmitted from the step platform 1, and the reference number of steps and the foot motion of the foot step that one of the left foot and the right foot is successively preceded. A switch unit 205 for inputting tempo setting data according to an operation, a RAM 204 for storing setting data input from the switch unit 205, a program ROM 203 and a memory 207 for storing accompaniment data, and a RAM 204 The accompaniment data stored in the program ROM 203 or the memory 207 is read out according to the tempo of the stepping motion to generate a musical sound, which is sent to the sound system of the step board 1 via the stereo cable 18, and an infrared communication unit The number of consecutive receptions of the left foot detection signal or the right foot detection signal received by 215 is the RAM. 04 when it reaches the stored reference number includes a CPU201 for changing the tone of the accompaniment music occurring sound effect, a.
Therefore, the monotonicity of the stepping motion is eliminated by the accompaniment music, and the number of consecutive steps of the preceding foot is notified by the change of the accompaniment music for each reference number, so that the foot is equally loaded. In addition, since the accompaniment is generated at a tempo set by the athlete, an optimum stepping tempo is possible for various users including men and women of all ages.

  In addition, a stepping motion support system according to a modified example of the first embodiment includes a step 1 for performing a stepping motion on a flat surface such as a floor, and a mobile phone 2 for outputting musical tones of an accompaniment to the stepping motion. However, as in the third embodiment shown in FIG. 32 (2), the step is counted on the step 1 side. That is, the step 1 generates a left foot detection signal in response to detection of a load applied to the upper plate 11a, and generates a right foot detection signal in response to detection of a load applied to the upper plate 11b. Then, the reference number N of steps is received from the mobile phone 2 as preset data of the count-up value. When the number of consecutive left foot detection signals or right foot detection signals reaches the reference number N, a change signal is transmitted to the mobile phone 2.

  On the other hand, the mobile phone 2 inputs from the switch unit 205 a switch unit 205 that inputs setting data including a reference value of a step and the tempo of the stepping motion that one of the left foot and the right foot successively precedes according to the operation. RAM 204 for storing the set data, a memory 207 for storing accompaniment music data, and a CPU 201 are provided. The CPU 201 transmits a reference value to the step 1, reads out accompaniment data stored in the memory 207 according to the tempo of the stepping motion stored in the RAM 204, generates a musical tone, and Output to the sound system. Further, when the CPU 201 receives a change signal from the platform 1, the CPU 201 controls the mobile phone 2 to change the musical sound of the accompaniment being generated into a sound effect.

Therefore, as in the first embodiment, the monotonicity of the stepping motion is canceled by the accompaniment music, and the number of consecutive steps of the preceding foot is notified by the change of the accompaniment music for each reference number. Since the stepping load is equally applied and the accompaniment is generated at the tempo set by the exerciser, the optimum stepping tempo can be achieved for various users including men and women of all ages.
Further, by simply adding a counter circuit and a flip-flop circuit, which are simple circuits, or a circuit equivalent to these to the step 1, the step can be counted on the step 1 side. As a result, the CPU 201 of the mobile phone 2 is released from the step counting process, so the load is reduced. Furthermore, since a two-way communication is possible with two communication lines, a standard number of times is transmitted from the cellular phone 2 to the platform 1 and a change signal is transmitted from the platform 1 to the cellular phone 2. Can be used.

Further, according to the first embodiment, the CPU 201 of the mobile phone 2 determines that when the number of consecutive left foot detection signals or right foot detection signals received from the platform 1 approaches the reference value N stored in the RAM 204, Control is performed so that the musical tone of the generated accompaniment is changed to a simple drum tone or a timpani tone.
Therefore, an exerciser who is not used to the stepping exercise is notified in advance that the timing of the stepping is near, so that the step change can be performed smoothly.

Further, according to the first embodiment, the CPU 201 of the mobile phone 2 outputs the generated musical sound of the accompaniment music to the sound system provided on the platform 1.
Therefore, the stepping motion can be performed while the accompaniment is pronounced by the speakers 16a and 16b of the step 1. In this case, only by causing the accompaniment to be pronounced from one step 2, a plurality of exercisers can perform a stepping exercise on each step. In addition, the headphone device connected to the headphone terminal 17 of the stepping platform 1 can perform the stepping motion by generating an accompaniment song. In this case, even in an environment where a loud sound can be heard, an accompaniment can be generated and a stepping motion can be performed.

In addition, according to the modification of the first embodiment, the mobile phone 2 outputs the generated analog accompaniment musical sound to the platform 1, and the platform 1 performs signal processing on the musical sound. , Infrared, Bluetooth, and other wireless signals are output to the headphone device.
Therefore, since no cable is connected to the headphone device, the stepping motion is not hindered.

Moreover, according to the said 1st Embodiment and 3rd Embodiment, a musical sound generator is comprised by the mobile telephone 2. FIG.
Therefore, it is possible to use the mobile phone 2 that is very widely used for generations as an accompaniment to the stepping motion. In addition, by using the mobile phone 2 that has established a mass production system, it is possible to construct an extremely inexpensive foot exercise support system.
Further, the mobile phone 2 stores the accompaniment data received from the distribution site via the network in the memory 207.
Therefore, the speed of the communication infrastructure by broadband and optical fiber, and the price competition of the communication charges of each communication company are rapidly progressing, so that favorite music can be obtained from the distribution site quickly and inexpensively as an accompaniment, With the widespread use of audio compression technology such as MP3 (MPEG-3 audio layer 3), many accompaniments can be stored in the memory 207 in a compressed state.

Further, according to the first embodiment, when the stepping exercise is finished, the CPU 201 of the mobile phone 2 calculates the influence of the stepping exercise on the exerciser as a quantitative numerical value.
For example, the CPU 201 calculates the calorie consumption of the exerciser based on the weight of the exerciser and the height of the step 1 in the setting data stored in the RAM 204 and the total number of stepping exercises stored in the RAM 204. To do.
Alternatively, the CPU 201 receives from the light receiving unit that receives the infrared light after the infrared light emitted from the internal light emitting unit is transmitted through a part of the body of the exerciser by the blood sugar level measuring unit 6 illustrated in FIGS. 25 and 26. Based on the obtained infrared light amount after transmission, the blood glucose concentration in a part of the body is calculated. Moreover, the calculated glucose concentration can be transmitted to a medical site, and an accurate blood glucose level can be received by analyzing the glucose concentration.
Therefore, not only the exerciser's stepping motion is supported, but also the health management of the exerciser can be supported by showing the physical state affected by the stepping exercise as a quantitative value.

As shown in FIG. 25, the blood glucose level measuring unit 6 has a shape like a clothespin having two optical cables 67a, 67b including optical connectors 66a, 66b, 68a, 68b, a rotating shaft 62 and a spring 63. As shown in FIG. 26 (1), the clip 61 sandwiches the earlobe and other body parts, and the infrared rays that pass through the earlobe and other body parts are absorbed by the blood glucose concentration and received. By utilizing the fact that the amount of light is smaller than the amount of light emitted, it is used as an index for measuring the blood glucose level. Further, as shown in FIG. 26 (2), after the infrared light emitted from the optical cable 67a is diverged by the rod lens 641a, the light path is changed to a substantially right angle by the prism 642a and irradiated to the earlobe 7, and then transmitted through the earlobe 7. The infrared ray is incident on the rod lens 641b by changing the optical path to a substantially right angle by the prism 642b, and is incident on the optical cable 67b.
Therefore, the blood glucose level can be measured with an instrument with a very simple structure, so that the physical and mental pain of diabetic patients can be eliminated compared to the conventional method of collecting blood by inserting a needle into a finger or earlobe. . Further, since the infrared optical path is changed by 180 degrees as a whole, the optical cables 67a and 67b do not get in the way when the earlobe or other part of the body is sandwiched by the clip 61 as shown in FIG.

Further, according to the first embodiment, the CPU 201 accumulates and stores the calculated calorie consumption and numerical values of the blood glucose level in the memory 207, and inputs a command to display the numerical value transition in the specified period from the switch unit 205. When it is done, based on the cumulative value of the numerical value in the period specified from the memory 207, the change of the numerical value in the specified period is displayed on the main display unit 2h in the form of a graph image.
Accordingly, it is possible to easily grasp the past body transition influenced by the stepping exercise.

  In each of the above-described embodiments and various other embodiments and modifications, accompaniment music data stored in the program ROM 203 or the memory 207 according to the stepping tempo set and stored in the RAM 204 is used. The configuration in which the mobile phone 2 is used as a musical sound generating device that reads out and generates musical sounds and sends them to the sound system of the stepping platform 1 or the headphone device 5 has been described. It is not limited to two. When the stepping exercise is performed, the mobile phone 2 does not transmit / receive a telephone call or mail, so the RF block 206 in FIG. 3 is not used. If there is a USB interface function or infrared communication function, use the communication function of a personal computer to connect to a distribution site or medical site, download a distribution song, and measure the glucose concentration in the blood of the earlobe It is possible to receive the blood glucose level. Therefore, except for the RF block 206, a stepping motion support system can be constructed by a portable musical sound generating device specialized for the stepping motion.

  For example, in the headphone device 5 shown in FIG. 29, instead of the signal processing unit 53, a dedicated musical sound generating device is configured with a configuration other than the RF block 206 in FIG. Then, the left foot detection signal and the right foot detection signal are transmitted from the platform 1 to the headphone device 5 by infrared or Bluetooth radio signals. Alternatively, since wireless communication with the outside is not performed, the left foot detection signal and the right foot detection signal are transmitted from the platform 1 to the headphone device 5 by a unique wireless communication method. In this case as well, as in the third embodiment, the rechargeable battery used in this musical tone generator has the same specifications as the rechargeable battery 115 of the step 1 shown in FIG. Then, a rechargeable battery sufficiently charged by the step 1 is attached to the musical sound generator, and the power of the step 1 is supplied from an indoor outlet via the AC adapter 117. Alternatively, if two rechargeable batteries are attached to the step 1 so that the battery can be charged, and the charged one is attached to the musical sound generator, there is no need to connect to an indoor outlet.

  According to such a dedicated tone generator, most of the electronic parts and other parts of the mobile phone can be used, and the production line of the existing mobile phone can be used, so that the product cost does not increase. On the contrary, in the main routine shown in FIG. 5 of the first embodiment, since the processing of step SA3 to step SA12 is not necessary, the control program in the program ROM 203 is reduced, and the CPU 201 is released from the load of communication processing, and the stepping motion Only processing is required. As a result, a musical sound generator can be realized even with an inexpensive CPU that operates at a relatively low speed. Further, according to this dedicated device, as shown in the first and second embodiments, the lower main body having the switch unit and the upper main body having the main display unit are folded by a hinge so as to be opened and closed. Only by making the shape of the lower main body into a shape that can be integrated with the support member 52 of the headphone device 5 shown in FIG. 29, the structure of the mobile phone can be used as it is. Furthermore, since it is not restricted by standardized communication protocols and interface specifications, it is possible to design with a very high degree of freedom, thereby reducing development cost and development time.

  In each of the above embodiments, the accompaniment music data is PCM waveform data created from a PCM recording of the actual performance music. However, the accompaniment music data is not limited to PCM waveform data. It may be accompaniment data created by software in a musical instrument or the like, or accompaniment music data created by a so-called physical sound source that mimics the structure of an actual acoustic instrument or the structure of a human vocal cord. In short, when multiple accompaniments are played sequentially or when one accompaniment is played repeatedly, the accompaniment clock always has a fixed period according to the set tempo, regardless of the middle part or the inter-song part. It is only necessary that the accompaniment data can be reproduced.

  In each of the above-described embodiments and various other embodiments and modifications, a system in which the CPU 201 executes an exercise support process program stored in the program ROM 203 of the mobile phone 2 is taken as an example. The exercise support processing program for executing the flowcharts in the embodiments is downloaded from a network such as the Internet directly or via a personal computer, or external storage such as a flexible disk, CD, or memory card. It is also possible to read from the medium, install it in the memory 207 or a writable program ROM, and execute it. In this case, the invention of the program is configured.

In other words, the stepping motion support processing program communicates with a stepping platform for performing a stepping motion that goes up and down one foot at a time on a flat surface such as the floor, and outputs an accompaniment musical sound for the stepping motion. A stepping motion support processing program installed in a musical sound generator,

And a third step for storing the setting data input in the second step in the first storage means, and a second storage at a reading speed corresponding to the tempo stored in the first storage means. A fourth step of reading accompaniment music data stored in the means to generate a musical sound signal and outputting it to a predetermined sound generation means; a first detection signal and a second detection signal received in the first step; of When it is detected by the output signal that the number of times or the time that one of the left foot and the right foot precedes in sequence has reached the reference number or time stored in the first storage means, output to the sounding means And a fifth step of changing the manner of pronunciation of the accompaniment being performed.

In addition, the stepping motion support processing program communicates with a stepping platform for stepping up and down one foot on a flat surface such as the floor, and outputs an accompaniment musical sound for the stepping motion. A stepping motion support processing program installed in a musical sound generator,

A second step of transmitting the input reference number or reference time to the platform, a third step of storing the tempo input by the first step in a first storage means, and the first step A fourth step of reading out accompaniment data stored in the second storage means at a reading speed corresponding to the tempo stored in the storage means, generating a musical tone signal and outputting it to a predetermined sounding means. And a first detection signal corresponding to detection of a load applied to the first step position on the upper surface of the step platform and a second detection signal corresponding to detection of a load applied to the second step position on the upper surface.

In addition, as shown in FIG. 27 of the first embodiment, the accompaniment music for the stepping motion can be downloaded from the distribution site to the mobile phone 2 via a network such as the Internet. Therefore, on the distribution site side, an accompaniment suitable for the stepping motion as shown in FIG. 17 is created and distributed. That is, an array of channels 3 and 4 which is an array of waveform data groups of discrete and sequential accompaniment composing a song including melody sounds and rhythm sounds, and an accompaniment piece for each waveform data of 2,205 accompaniment pieces Accompaniment composed of a specific tone color synchronized with a plurality of accompaniment clocks and every ten accompaniment clocks in the arrangement of channel 1 of the accompaniment clock synchronized with the waveform data of the music, and before and after the music (or just before the music) Rhythm waveform data channel 2 array, and channel 3 effect sound waveform data and effects that are different from the timbre of the accompaniment waveform data group at the end of the song (or the beginning of the song) The accompaniment distributed by the arrangement of the accompaniment clock of channel 1 synchronized with the waveform data of the sound is configured.
