In the age setting mode, the contents of the age register AGE are numerically displayed and output on the display unit 4 (step W9), and the up SW 15 or down SW 16 (hereinafter abbreviated as up / down SW 15, 16) is turned on ( It is checked whether or not it has been turned on (step W10). When the up / down SWs 15 and 16 are turned on, the contents of the age register AGE are changed according to the turning on of the up / down SWs 15 and 16 (step W11), and it is checked whether or not the set / start SW 12 is turned on. (Step W12). When the set / start SW12 is not turned on, it is judged that the age setting is not completed, and it is checked whether or not the clear / stop SW14 is turned on (step W13). When the clear / stop SW14 is turned on, It is determined that all the settings have been redone, the registers and flags are cleared, and the process returns to step W1 (step W14). If the clear / stop SW 14 is not turned on in step W13, the process returns to step W8 to continue the age setting mode and perform the same processing. When the up / down SWs 15 and 16 are turned on in step W10 and the contents of the age register AGE are changed in step W11, the changed age value is displayed and output on the display unit 4 in step W9.

That is, the user of the automatic performance device 1 looks at the display on the display unit 4 and turns on (turns on) the up SW 15 or the down SW 16 to set the numerical value displayed on the display unit 4 to his own year. Set to decree.

After that, when the set / start SW 12 is turned on in step W12, it is determined that the age setting mode is completed, and "1" is set in the gender flag register (step W15) to set the gender. Enter the mode.

In the weight setting mode, the contents of the weight register W are numerically displayed on the display unit 4 (step W25). In the weight register W, a general weight, for example, the average weight of the Japanese people is set by the initial process (step W1). Next, it is checked whether or not the up / down SWs 15 and 16 are turned on (step W26), and when the up / down SWs 15 and 16 are turned on, the contents of the weight register W according to the turned-on up SW 15 or down SW 16 Is changed (step W27) to check whether the set / start SW 12 is turned on (step W28). If the set / start SW 12 is not turned on, it is determined that the weight setting mode is not completed, and it is checked whether the clear / stop SW 14 is turned on (step W29). When the clear / stop SW 14 is turned on, After determining that the setting mode has been cleared and clearing the registers and flags (step W30), the process returns to step W1. If the clear / stop switch 14 is not turned on, it is determined that the weight setting mode has not been completed, the process returns to step W24, and the same processing is performed. If the up / down SWs 15 and 16 are not turned on in step W26, it is checked whether the set / start SW 12 is turned on without changing the contents of the weight register W (step W28).

That is, the user of the automatic musical instrument 1 can set his / her weight by turning on the up SW 15 or the down SW 16 in the weight setting mode.

When the set / start SW 12 is turned on in step W28, it is determined that the weight setting mode is completed, and then the "pulse" segment 28 is blinked (step W31) to enter the safe vein setting mode. enter.

In the safe vein setting mode, the contents of the safe vein register AM are displayed numerically (step W32). The CPU 40 reads the maximum pulse rate from the pulse table stored in the ROM 41 on the basis of the set age and sets it in the stable pulse register AM as the safe vein rate.

After that, it is checked whether or not the up / down SWs 15 and 16 are turned on (step W33), and when the up / down SWs 15 and 16 are turned on, the rest depending on the turned-on up SW 15 or down SW 16 is performed. The contents of the pulse register AM are changed (step W34), and the process proceeds to step W35 in FIG. When the up / down SWs 15 and 16 are not turned on, the process directly proceeds to step W35 in FIG. 12 to check whether the set / start SW 12 is turned on. When the set / start SW 12 is not turned on, it is judged that the safety vein setting mode is not completed, and it is checked whether the clear / stop SW 14 is turned on (step W36). When the clear / stop SW 14 is turned on. , It is determined that the setting mode has been cleared, each register and flag are cleared, and the process returns to step W1 (step W37). When the clear / stop SW 14 is not turned ON in step W36, the process returns to step W31 and the vein vein setting process is performed in the same manner.

That is, in the safe vein rate setting mode, by turning on the up SW 15 and the down switch 16 while watching the safe vein rate displayed on the display unit 4, it is possible to set the own rest pulse rate.

When the set / start SW 12 is turned on in step W35, the safe vein setting mode is ended, "1" is set in the training mode flag register (step W38), and the training mode setting mode is entered. .

In the training mode setting mode, first, it is checked whether or not the training mode flag is “1” indicating the general training mode (step W39), and when the training mode flag is “1”, the “general” training segment 1 is selected. 8 is blinked (step W40), and it is checked whether the down SW 16 is turned on (step W42). If the training mode flag is not "1" in step W39, the "reduction" training segment 19 is made to blink (step W41), and it is checked whether or not the down SW 16 is turned on (step W42).

When the down SW 16 is turned on in step W42, the training mode flag is inverted (step W43), and it is checked whether or not the set / start SW 12 is turned on (step W44). When the set / start SW 12 is not turned on, it is judged that the training mode setting mode is not completed, and it is checked whether the clear / stop SW 14 is turned on (step W45). When the clear / stop SW 14 is turned on, When it is determined that the setting mode has been cleared, each register and flag are cleared (step W46), and the process returns to step W1. If the clear / stop SW 14 is not turned on in step W45, the process returns to step W39 and the training mode setting mode is similarly processed.

That is, in the training mode setting mode, the user determines the training mode based on whether the blinking of the segment portion 5 is the “general” training segment 18 or the “weight reduction” training segment 19, and turns on the down SW 16. Therefore, the general training mode and the weight loss training mode can be selected.

Then, in step W44, when the set / start SW 12 is turned on, the training mode setting mode is ended and the training time setting mode is entered.

In the training time setting mode, first, the "time" segment 17 is blinked (step W37), and the contents of the timer register TM are numerically displayed on the display unit 4 (step W48). A general training time, for example, 30 minutes is set in the timer register TM by the initial processing in step W1.

Next, it is checked whether or not the up / down SWs 15 and 16 are turned on (step W51). When the up / down SWs 15 and 16 are turned on, depending on the turned-on up SW 15 or down SW 16, After changing the contents of the timer register TM (step W50), it is checked whether or not the set / start SW 12 is turned on (step W51). If the up / down SWs 15 and 16 are not turned on in step W49, the process directly proceeds to step W51 to check whether the set / start SW 12 is turned on.

When the set / start SW 12 is not turned on in step W51, it is determined that the training time setting mode is not completed, and it is checked whether or not the clear / stop SW 14 is turned on (step W52). When 4 is turned on, it is determined that the setting mode has been cleared, each register and flag are cleared (step W53), and the process returns to step W1. When the clear / stop SW 14 is not turned on in step W52, the process returns to step W47 and the training time setting mode is similarly processed.

That is, in the training time setting mode, the user of the automatic performance device 1 sets the training time to an arbitrary time by turning on the up SW 15 or the down SW 16 while looking at the display contents of the display unit 4. can do.

When the set / start SW 12 is turned on in step W51, the training time setting mode is ended and the pulse range calculation process is started.

In the pulse range calculation process, as shown in FIG. 13, first, based on the contents of the age register AGE, the maximum pulse rate is read from the pulse table shown in FIG. 4 and stored in the register A (step W54), based on the content of the gender flag register, the gender coefficient is read from the gender coefficient table and stored in the register B (step W55). Next, the general training coefficient is stored in the register C and the weight reduction training coefficient is stored in the register D based on the contents of the training mode flag register (step W56). Each coefficient is stored in advance in the ROM 41 or the RAM 42. For example, as a general training coefficient, the upper limit pulse rate is 80% of the maximum pulse rate which is the allowable pulse rate determined by age and sex, and the lower limit is set. The pulse rate is set to 70% of the maximum pulse rate. As the weight loss training coefficient, the upper limit pulse rate is 70% of the maximum pulse rate, and the lower limit pulse rate is 60% of the maximum pulse rate. The gender coefficient is set to 1 for males and 0.6 to 0.7 for females, for example.

Then, based on the contents of the weight register W, the age register AGE and the sex flag, a proportional constant used for calorie calculation which will be described later is calculated and stored in the register K (step W57). Next, the upper limit pulse rate and the lower limit pulse rate are calculated and stored in the upper limit pulse register UM and the lower limit pulse register LM, respectively (steps W58 and W59). The upper limit pulse rate is calculated by multiplying (A × B × C) each value stored in the register C to the register C in the processing of steps W54 to W56, and the lower limit pulse rate is It is calculated by multiplying (A × B × D) the respective values stored in the register A, the register B, and the register D in the processing from step W54 to step W56.

That is, in the pulse calculation process, the upper limit pulse rate and the lower limit pulse rate are calculated, and the proportional constant used in calorie calculation is calculated.

Now, assuming that the user of the automatic performance device 1 is a 35-year-old male, the maximum pulse rate of the 35-year-old man is 185 and the sex coefficient is 1 from FIG. The lower limit pulse rate is: upper limit pulse rate = 185 × 0.7 × 1 = 129.5, lower limit pulse rate = 185 × 0.6 × 1 = 111.

When the pulse calculation process is completed, the tempo setting mode is entered.

In the tempo setting mode, first, the “tempo” segment 21 is made to blink (step W60), and the contents of the tempo counter TC are numerically displayed and output on the display unit 4 (step W61). A general tempo is set in the tempo counter TC by the initial processing in step W1.

Next, it is checked whether or not the up / down SWs 15 and 16 have been turned on (step W62). When the up / down SWs 15 and 16 are turned on, the up / down SWs 15 and 16 are turned on in response to the turned-on up SW 15 or down SW 16. The contents of the tempo counter TC are changed (step W63), and it is checked whether the set / start SW 12 is turned on (step W64). If the up / down SWs 15 and 16 are not turned on in step W62, the contents of the tempo counter TC are not changed and the process proceeds to step W64 to check whether the set / start SW 12 is turned on.

When the set / start SW 12 is not turned on in step W64, it is determined that the tempo setting is not completed, and it is checked whether or not the clear / stop SW 14 is turned on (step W65), and the clear / stop SW 14 is turned on. When turned on, it is determined that the setting mode has been cleared, each register and flag are cleared (step W66), and the process returns to step W1.

If the clear / stop SW 14 is not turned on in step W65, the process returns to step W60 and the tempo setting process is similarly performed.

When the set / start SW 12 is turned on in step W64, it is determined that all the settings have been completed, and the process returns to step W1.

Then, when the mode switch 11 is turned on in step W1, the setting mode flag is inverted to “0” (step W2), and the determination in step W3 becomes NO, and steps W4 and W6 are executed. Then, the SW process ends. When the set / start SW 12 is turned on in step W4, the start mode flag for setting the start of automatic performance is set to "1" (step W5).

In this way, the tempo of the automatic performance can be set according to various conditions by the SW processing.

When the SW process is completed, the process returns to FIG. 7 and the pulse process is performed.

<Pulse Processing> In pulse processing, the pulse of the human body is detected and accumulated at predetermined time intervals, and the accumulated pulse rate is set as the upper limit pulse rate and the lower limit pulse rate at predetermined time intervals. This is a process of setting a flag designating up / down of the tempo by comparing, calculating calories, and outputting the calorie for display.

That is, in the pulse processing, as shown in FIG. 14, first, it is checked whether or not the start flag is "1" (step M1). When the start flag is "0", the automatic performance is not started. Then, the pulse processing is terminated as it is.

When the start flag is "1", it is checked whether or not the value of the pulse measurement time counter n is a predetermined value N set in advance (step M2), and the value of the pulse measurement time counter n becomes the predetermined value N. At this time, it is determined that it is the timing of capturing the pulse, the pulse measurement time counter n is reset to "0" (step M3), and the pulse data m is captured from the pulse detector 47 (step M4). The pulse measurement time counter n is accumulated by the timer processing described in FIGS. 8 and 9.

Next, the value of the pulse data accumulation register M for calorie calculation is added to the captured pulse data m, and the result is stored in the pulse data accumulation register M, and the pulse data for average value calculation is also added. The pulse data m is added to the value of the accumulation register HM and stored in the pulse data accumulation register HM (step M5). Next, the pulse count register P, which stores the number of times the pulse is captured, is incremented by "1" (step M6), and it is checked whether the value of the pulse count register P has reached a preset value L (step S6). Step M7).

When the value of the pulse count register P is the predetermined value L, it is determined that the calorie calculation timing is reached, the value of the pulse data accumulation register HM is multiplied by the predetermined value L, and the average pulse rate is calculated. Is calculated, the multiplication result (HM / L) is stored in the average pulse data register hm (step M8), and the pulse number register P is set to “0” (step M9).

Then, it is checked whether the average pulse rate stored in the average pulse data register hm is larger than the upper limit pulse rate stored in the upper limit pulse register UM (step M10), and the average pulse rate is determined to be the upper limit pulse rate. When the number is larger than the number, it is determined that the training pace is too fast, the tempo down flag register TDF is set to "1" (step M11), and the process proceeds to step M14. In step M10, when the average pulse rate is less than or equal to the upper limit pulse rate, it is checked whether the average pulse rate stored in the average pulse rate data register hm is smaller than the lower limit pulse rate stored in the lower limit pulse rate register LM. If the average pulse rate is smaller than the lower limit pulse rate (step M12), it is determined that the training pace is too slow, and the tempo up flag register TUF is set to "1" (step M13). Transition. If the average pulse rate is equal to or higher than the lower limit pulse rate in step M12, the process directly proceeds to step M14. That is, by comparing the average pulse rate with the upper limit pulse rate and the lower limit pulse rate, the pulse rate of the human body during training is evaluated, and in order to increase or decrease the tempo of the automatic performance according to this evaluation. , The tempo down flag register TDF and the tempo up flag register TUF are set.

In step M14, calorie is calculated by the following equation and stored in the calorie register CAL, and then the "CAL" segment 27 is blinked (step M15).

CAL = (W × M × K) / (13 × M0) Here, M is the total number of pulses during training (value of pulse data accumulation register M), W is weight (value of weight register W) ), M0 is the resting pulse rate per minute (the value of the stable pulse register AM), and K is the proportional constant for correction (determined by the data such as age, gender, and weight input by the above SW processing). Will be done).

This calculation formula is derived from the fact that the energy consumption during training such as jogging is almost proportional to the oxygen consumption.

That is, the blood volume of the human body is approximately equal to one-third of the weight of the person (blood volume ≈ weight ÷ 13), and the whole blood of the human body circulates in the body in about 1 minute at rest. Therefore, the volume of blood delivered by a single heartbeat is calculated by dividing the volume of blood by the resting pulse rate (volume of blood delivered by a single heartbeat = blood volume ÷ resting pulse rate). Since the amount of oxygen bound to hemoglobin in the blood is usually constant, the calorie consumption can be calculated by the above formula.

Then, the calculated value of the calorie register CAL is numerically displayed and output to the display unit 4 (step M16), and the pulse processing is ended.

Then, when the pulse measurement time counter n does not reach the predetermined value N in step M2, it is determined that the pulse acquisition timing has not come, and the process shifts to step M15 to blink the “CAL” segment 27. After that, the calorie value stored in the calorie register CAL is numerically displayed and output to the display unit 4 (step M16). If it is determined in step M7 that the pulse rate register P does not reach the predetermined value L, it is determined that the calorie calculation timing has not come and the process proceeds to step M15 to similarly perform the "CAL" segment 27. After blinking, the calorie value stored in the calorie register CAL is numerically displayed and output on the display unit 4 (step M16).

As described above, in the pulse processing, the pulse is detected and accumulated at each predetermined timing N, the average pulse is calculated at each predetermined timing L, and the average pulse is calculated as the upper limit pulse rate and the lower limit pulse rate. Compare with the number. Then, depending on whether the average pulse rate is higher than the upper limit pulse rate or lower than the lower limit pulse rate, the state of the tempo up flag register TUF and the tempo down flag register TDF for raising and lowering the tempo is set, and The calorie is calculated, and the calculated calorie value is displayed numerically on the display unit 4.

When the pulse processing is completed, next, the rhythm processing shown in FIG. 7 is performed.

<Rhythm Processing> The rhythm processing is processing for setting a tempo (rhythm) to be automatically played according to the tempo up flag register TUF and the tempo down flag register TDF set in the above pulse processing. Processed as shown.

That is, in the rhythm process, first, it is checked whether or not the start mode flag is "1" (step R1), and when the start mode flag is "0", it means that the automatic performance mode has not been entered. The rhythm process ends without making any rhythm settings. When the start mode flag is "1", it is checked whether the warming up flag is "1" (step R2). When the warming up flag is "0", the warming up is in progress and the rhythm is not set. Then, the rhythm process is ended as it is. When the warming up flag is "1", it is judged that the warming up is completed, and it is checked whether the tempo down flag is "1" (step R3).

In step R3, when the tempo down flag is "1", the value of the tempo counter TC is subtracted by a preset predetermined value K, and the subtraction result is stored in the tempo counter TC (step R4). , Set the tempo down flag to "0" (step R5). As a result, the tempo of automatic performance can be lowered.

In step R3, when the tempo down flag is "0", it is checked whether the tempo up flag is "1" (step R6). When the tempo up flag is "1", the value of the tempo counter TC is changed. Only the predetermined value K is added, the addition result is stored in the tempo counter TC (step R7), the tempo up flag is reset to "0" (step R8), and the rhythm process is ended. This can increase the tempo of automatic performance.

Further, when the tempo down flag is “0” in step R3 and the tempo up flag is “0” in step R6, it is determined that the tempo adjustment is not necessary, and the rhythm process is ended as it is. .

As described above, the rhythm process allows the tempo to be adjusted according to the states of the tempo up flag T UF and the tempo down flag TDF set in the pulse process.

When the rhythm process is completed, the tone generation process of FIG. 7 is performed.

<Sound Generation Process> The sound generation process is a process of reading performance data from the performance data card 9 in accordance with the tempo set in the rhythm process and performing an automatic performance while considering the warm-up time. It is processed as shown in.

That is, in the sound generation process, first, it is checked whether the start mode flag is "1" (step H1). If the start mode flag is "1" and the automatic performance mode is set, the first performance data is recorded. Whether or not there is any, that is, whether or not it is the first processing after starting the automatic performance, is checked by whether or not the initial flag is "1" (step S2). When this initial flag is "1", it indicates that it is the first process after starting the automatic performance, and is set to "1" by the initial process of FIG.

Now, assuming that this is the first process after starting the automatic performance, the process moves to step S3, the note length data stored at the first address of the performance data card 9 is read out, and the note length counter reads it. Set (step S3).

Next, it is checked whether or not the tempo of the next musical tone is reached by the value of the time accumulation register Q for tempo and the value of the tempo counter TC (step H4), and the time accumulation is performed. When the value of the register Q does not reach the value of the tempo counter TC, it is determined that the timing of generation of the next note has not come, and the process moves to step H11, and the timer register TM sets the warm-up end time IT. Check if it has become. The warm-up time IT is stored in the ROM 41 or the RAM 42 in advance, but may be set by the SW process. If the timer register TM has not reached the warm-up time IT, it is determined that the warm-up is not completed, and it is checked whether the timer register TM is "0" (step H13), and the timer register TM is set to "0". , It is judged that the automatic performance is not started, that is, the training is not started, and the start mode flag and the warm-up flag are set to “0” and the initial flag is set to “1”. (Step H15), the tone generation processing is ended.

When the timer register TM is not "0" in step H13, it is checked whether the clear / stop SW14 is ON (step H14). When the clear / stop SW14 is turned ON, the automatic performance mode is released. Then, the start mode flag and the warming-up flag are set to "0", the initial flag is set to "1" (step H15), and the tone generation processing is terminated.

When the clear / stop SW 14 is not turned on in step H14, the tone generation processing is ended as it is.

When the value of the time accumulation register Q reaches the value of the tempo counter TC in step H4, it is determined that it is the timing to start the generation of the next note, and the time for the tempo is determined. After resetting the accumulation register Q to "0" (step H5), the time length time accumulation register R is incremented (step H6), and the incremented value of the time accumulation register R is the musical tone currently being sounded. It is checked whether or not the value of the note length counter, which is the note length of, has been reached (step H7). Now, since the first note is being sounded, it is wondering whether the value of the time accumulation register R has become the note length. When the value of the time accumulation register R has not reached the value of the note length counter, the process proceeds to step H11, where it is checked whether the timer register TM has reached the warming up time IT, and the timer register TM does not. When the ming-up time IT has not come, similarly to the above, the process shifts to step H13 and it is checked whether the timer register TM is "0". When the timer register TM is not "0", it is checked whether or not the clear / stop SW 14 is turned on (step H14), and when it is not turned on, the sound generation processing is ended as it is.

Then, in step H7, when the value of the time accumulation register R reaches the value of the note length counter, it is determined that the pronunciation time of the note being sounded has ended, and the time accumulation register R is set to "0". (Step H8), the note length and pitch data of the next note is read from the performance data card 9, the note length data is stored in the note length counter in the same manner as described above, and the initial flag is set to "0". (Step H9). Next, the pitch data and ON data for instructing the start of sound generation are supplied to the sound source 44 to start the sound generation of the next note (step H10). Then, it is checked whether the value of the timer register TM reaches the warm-up time IT (step H11). If the value of the timer register TM does not reach the warm-up time IT, the process proceeds to step H13 and the same as above. To process.

By repeating the above processing in sequence, the notes stored in the performance data card 9 are pronounced with the note length and with the rhythm set in the tempo counter TC in the rhythm processing shown in FIG. Since the value of the timer register TM has not reached the warming-up time IT, the tempo is not raised or lowered in the rhythm process, and the tempo set in the tempo setting process of the SW process is set in the tempo counter TC. It Therefore, during the warm-up time, the tempo set by the SW process is automatically performed.

After that, in step H11, when the value of the timer register TM reaches the warming up time IT, the warming up flag is set to “0” (step H12), and the timer register TM and the clear / stop are set in the same manner as above. SW14 is checked (steps H13 and H14). Here, since the warming up flag is set to "0", the value of the tempo counter TC is increased or decreased in the next rhythm process based on the tempo up flag and tempo down flag set by the pulse process. , When the time accumulation register Q reaches the value of the up or down tempo counter TC, it is confirmed that only the note length of the note currently being pronounced is pronounced, and the pronunciation of the next note is started (step H5-step H10).

Therefore, until the warming-up time is completed, automatic performance is performed at the tempo set by the SW process or at the normal tempo, and when the warming-up time is completed, the pulse rate of the human body during training is detected, and this detection is performed. Based on the pulse rate, the tempo set by the SW process can be raised or lowered to automatically perform the performance. That is, when the detected human body pulse rate exceeds the upper limit pulse rate, the automatic performance tempo is decreased, and when the detected human body pulse rate is lower than the lower limit pulse rate, the automatic performance tempo is increased. You can The tempo of the automatic performance is adjusted by changing the read speed at which the performance data is read from the performance data card 9, so that the performance pitch is not affected and the performance is natural. Can be played.

The method of calculating the energy consumption amount during training is not limited to the above method, and may be calculated based on the moving distance, for example.

That is, it can be calculated by energy consumption = proportional constant × body weight × movement distance, and the movement distance is calculated by speed in jogging × time. Since this speed can be obtained from the stride (step length) of jogging and the pitch per unit time (steps / hours), input the stride, pitch and weight in the above SW process and measure the time. Thus, the energy consumption amount during jogging can be calculated.
