FIG. 4 is a diagram showing the overall flow of the display operation of the display section 2 of the first embodiment. In the time display mode (M=0 and F=0) in figure a, the 25th,
Wednesday, 10pm, 50 minutes and 30 seconds is displayed on display section 2. This time display mode (M=0, F=0)
When the key _S2 is operated, the mode is switched to the time set mode (M=0 and F=1) shown in FIG. 5B, and the time can be set (corrected). When setting (correcting) the time, each digit of the time is selected using the key S _B , and after selecting the desired digit, the desired time can be set (corrected) by operating the key _SA .

Furthermore, when key _S2 is operated in the time set mode, the mode switches to the time display mode again.

Next, in the time display mode (M=0 and F=0), when the key _S1 is operated, the mode is switched to the rhythm sound selection mode (M=1, F=0 and P=0) shown in FIG. In this rhythm sound selection mode, by operating key S _B as described later, rhythm sounds can be selected in the following order: electronic pop → salsa → shuffle → disco → rock → electronic pop →... I can do it. next,
When the key _S2 is operated in the rhythm tone selection mode, the mode is switched to the timer set mode (M=1 and F=1) as shown in d of the figure. In the timer set mode, as in the time set mode, each digit of the timer time can be selected by operating the key S _B , and the desired timer time can be set (corrected) by operating the key S _A. can. Further, in this timer set mode, after setting the desired timer time, by operating the key _S2 , the mode returns to the rhythm sound selection mode.

Rhythm sound selection mode (M=1 and F=0 and P
= 0), by operating key S _A , the mode changes to the timer measurement mode shown in e of the figure, and the rhythm sound selected in the rhythm sound selection mode is generated continuously during the timer time memorized in the timer set mode. do. Furthermore, even in the time display mode, by operating the key S _A , the timer can be started and the generation of rhythm sounds can be started. Note that the mode shown surrounded by a broken line in FIG. 4 is called an exercise mode (M=1 and F=0).

Next, FIG. 5 is a diagram showing the display operation of the above-mentioned exercise mode, where A shows the rhythm sound selection mode of FIG. 4c, and FIG. 5B shows the timer measurement mode of FIG. 4e. There is. However, a in Figure 5A
2 shows the state of the display unit 2 when an instruction is given not to report the rhythm sound during timer measurement, and the mark display body 2b indicating the selected rhythm sound is all unlit. In addition, a timer time of 5 minutes preset in the timer set mode is displayed on the display section 2.
00 seconds is displayed. When the key S _A is operated in this state, timer measurement is started and the mark display body 2d blinks as shown in FIG. At this time, since the rhythm sound is not selected, no rhythm sound is generated during the timer measurement, and when the 5-minute timer period ends, the mark display body 2d changes from blinking to lighting as shown in c of the same figure, and the timer measurement ends. In this way, when an instruction is given not to report the rhythm sound during timer measurement, the mark display body 2c does not light up during timer measurement, and the measurement ends after the timer time expires.

On the other hand, when key S _B is operated in the state shown in figure a, the electronic pop (E.POP) rhythm sound is selected, and the mark display 2b corresponding to electronic pop (E.POP) lights up. (See figure d). When the key S _B is operated again in this state, the next rhythm sound of salsa (SALSA) is selected, and the mark display body 2b corresponding to the rhythm sound of salsa (SALSA) lights up (see e in the figure). Thereafter, by operating the key S _B in the same way, you can sequentially select the rhythm sounds of SHUFFLE, DISCO, and ROCK, and the mark display 2b corresponding to each rhythm sound will light up ( (See f, g, h in the same figure). Further, when the key S _B is operated, the state returns to the state shown in a of the figure again and the rhythm sound is not selected.

In this manner, by operating the key S _B , a desired rhythm sound can be selected, and the selected rhythm sound can be confirmed by lighting the mark display body 2b.

In addition, the electronic pop is selected as the rhythm sound to be sounded during timer measurement.
When key S _A is operated in this state, timer measurement is started as shown in i in the same figure, and output of the rhythm sound of the selected electronic pop is started. As shown in Figure i, the mark display 2c lights up while the rhythm sound is being sounded, and the mark display 2d blinks to indicate that the timer is operating. During timer measurement, the remaining timer time is displayed on the display unit 2 in minutes and seconds.

FIG. 2J is a diagram showing the state of the display section 2 after the timer measurement ends, and the mark display body 2c is turned off.
The mark display body 2d lights up and the timer time is 00.
Minutes 00 seconds are displayed. When the timer measurement ends, an end sound such as a buzzer sound is generated, and then the rhythm sound of salsa is automatically selected as shown in k to l in the same figure, and the mark display 2b corresponding to salsa is lit, indicating that the timer is operating. The mark display 2d indicating this is blinking, and the 5-minute timer measurement starts again, and the salsa rhythm sound is sounded.

When the 5-minute timer measurement of the salsa rhythm sound is completed, the next shuffle rhythm sound is automatically selected as shown in m in the figure, and the shuffle rhythm sound is sounded for 5 minutes. Thereafter, in the same way, rhythm sounds are automatically selected in the order of Shuffle → Disco → Rock, and after the Rock rhythm sound, the electronic pop rhythm sound is automatically selected again.

Furthermore, even if the rhythm sound selected before the timer measurement starts is a rhythm sound other than electronic pop, the next rhythm sound will be automatically selected in sequence after the timer measurement ends, and the rhythm sound notification will continue. It is done.

Next, the above-mentioned display processing operation performed under the control of the microprogram stored in the ROM 4 will be explained based on FIGS. 6 to 8.

FIG. 6 is a flowchart showing the flow of the entire circuit (system) shown in FIG. The system receives a clock signal of a constant period from the frequency dividing circuit 13,
Otherwise, unless a key signal is output from the key input section 12 to the ROM address control section 5, it remains in the HALT state (step _a1 ). and,
When a clock signal of a constant period is output from the frequency dividing circuit 13 to the ROM address control unit 5, an address is output from the ROM address control unit 5 to the ROM 4.
Execution of the time measurement program stored in the ROM 4 is started, and time measurement processing, which will be described in detail later, is performed (step a ₂ ). After the timing process is completed, the display processing program stored in the ROM 4 is executed and the display is displayed on the display unit 2 (step
_a3 ). Thereafter, the process returns to the HALT state (step _a1 ).

On the other hand, in the HALT state, the key
When any of the keys S ₁ , S ₂ , S _A , and S _B is operated, a key signal corresponding to the operated key is output from the key input unit 12 to the ROM address control unit 5 , and the ROM address is The start address of the key processing program is output to the ROM 4 via the control unit 5, and execution of the key processing program is started to perform key processing (step _a4 ). After the key processing is completed, return to step a ₁ and HALT.
state.

Next, FIG. 7 is a flowchart showing the detailed flow of the key processing.

In the same figure, it is first determined in step b ₁ whether or not key S ₁ has been operated. If key S ₁ has been operated, in step b ₂ the value of status flag F is set to "0", that is, the display mode (F =0). Then, display mode (F=
0), it is determined in step _b3 whether the value of the status flag M is "0" or not, and M=0, that is, the time display mode of FIG. 4a (M=0 and F=
0), the value of the status flag M is set to "1" in step _b4 , and the mode is switched to the rhythm tone selection mode (M=1 and F=0) shown in FIG. 4c.

On the other hand, if the value of the status flag M is "1" in step _b3 , that is, the rhythm sound selection mode (M=1 and F=0), the value of the status flag M is set to "0" in step _b5 and the Switch to the time display mode (M=0 and F=0) shown in Figure 4a. Further, if the value of the status flag F is "0" in step _b2 , no processing is performed and the process ends.

That is, by operating the key _S1 , switching is performed between the time display mode (M=0 and F=0) in FIG. 4a and the rhythm sound selection mode (M=1 and F=0) in FIG. 4c. .

On the other hand, the key operated in step b ₁ above is the key
If S ₁ is not the case, the process advances to step b ₆ to determine whether key S ₂ has been operated, and if key S ₂ has been operated, it is determined whether the value of status flag M is "0" in step b ₇ . A determination is made, and if it is the time mode (M=0), it is determined in step _b8 whether the value of the status flag F is "0". And step b ₈
If the value of the status flag F is "0", that is, the time display mode shown in FIG. 4a (M=0 and F=0),
In step _b9 , the value of the status flag F is set to "1" and the time set mode (M=0 and F=
Switch to 1). Further, if the value of the status flag F is "1", the value of the status flag F is set to "0" in step _b10 , and the mode is changed from the time set mode to the time display mode (M =0 and F=
0).

On the other hand, if the value of the status flag M is "1" in step _b7 , the process advances to step _b11 and the status flag F is
It is determined whether the value of P is "0", that is, whether the mode is exercise mode or not. If it is "0", the value of the status flag P is set to "0" in step _b12 .
Determine whether it is. Then, P=0, that is, the rhythm sound selection mode of FIG. 4c (M=1 and F=
0 and P=0), the value of the status flag F is set to "1" in step _b13 , and the mode is switched to the timer set mode (M=1 and F=1) shown in FIG. 4d.
Further, if the value of the status flag P is "1" in step _b12 , no processing is performed and the process ends.

On the other hand, if the value of the status flag F is "1" in _{step b11} , that is, the timer set mode shown in FIG. (M=1 and F=
0 and P=0), in step _b15 , the timer time value set in the timer set mode and stored in the timer storage register T is transferred to and stored in the timer operation register S.

That is, by operating the key _S2 , the time display mode (M=0 and F=0) and the time set mode (M=
0 and F=1), and the _timer set mode (M=
1 and F=1) and rhythm sound selection mode (M=1 and F=0 and P=0).

On the other hand, if it is determined in step b ₆ that key S ₂ has not been operated, it is determined in step b ₁₆ whether key S _B has been operated, and if key S _B has been operated, step b ₁₇ is performed. and status flags M and F
If the exercise mode (M=0 and F=0), the hex counter K is determined at step b ₁₈ .
Add 1 to the value. Each time the hexadecimal counter K is incremented by 1, it changes from 0 → 1 → 2 → 3 → 4 → 5 → 0 → 1 →...
Store the values in order. Next, the process proceeds to step b ₁₉ , and it is determined whether the value of the status flag P is "0", that is, whether the timer is measuring. If the timer is not measuring (P=0), the process proceeds to step b _20.
Transfers the timer time stored in the timer storage register T to the timer operation register S, and executes the step
b The rhythm sound newly selected in ₂₁ (excluding cases where it has not been selected) is sounded for a certain period of time (demonstration sound generation).

On the other hand, in step _b19 , the value of status flag P is “1”
That is, if the timer is measuring, the process is immediately terminated, and the rhythm sound selected in the time measurement process is generated as described later. In this way, when key S _B is operated in exercise mode (M = 1 and F = 0), unless the timer is measuring (P =
0), the new rhythm sounds are electronic pop (K=1) → salsa → (K=2) → shuffle (K=3) → disco (K=4) → rock (K=
5) → unselected (K=0). Since the newly selected rhythm sound is sounded for a certain period of time, the selected rhythm sound can be confirmed. On the other hand, if key S _B is operated during timer measurement, only the rhythm sound is selected (changed) and the value of timer operation register S is not changed, so the newly selected rhythm sound is changed to the current one. The alarm will continue to sound from the timer time.

On the other hand, if it is not the exercise mode (M=1 and F=0) in step _b17 , it is checked in step _b22 whether the value of the status flag F is "1", that is, the time set mode (M=0 and F=1). ) or timer set mode (M=1 and F=1), and if it is time set mode or timer set mode, the set digit in each mode is selected in step _b23 .

That is, time set mode (M=0 and F=
1) or timer set mode (M=1 and F=
By operating key S _B in step 1), the set digit can be selected. Also, the above steps
b If the status flag F is "0" at ₂₂ , that is, if the time display mode (M=0 and F=0), the process ends without performing any processing.

On the other hand, if the key S _B is not operated in step b ₁₆ , that is, if the key S _A is operated, then in step b ₂₄ , the value of the status flag F is "0", that is, the display mode (F=0). If it is the display mode, it is determined in step _b25 whether the value of the status flag P is "1", that is, whether the timer is operating. And the timer is running (P
= 1), the status flag P is reset to "0" (step _b26 ), and if the timer is not operating (P
=0), and the status flag P is set to "1" (step _b27 ).

In other words, the timer operation can be stopped by operating key S _A while the timer is operating.
Operation of the timer is started by operating key S _A while the timer is stopped.

On the other hand, in step _b24 , the value of status flag F is “1”
That is, time set mode (M=0 and F=1)
or timer set mode (M=1 and F=1)
If so, in step _b28 , the data of the set digit is set (corrected) in the selected set mode of the above two set modes.

That is, time set mode (M=0 and F=
1) or timer set mode (M=1 and F=
0), the data of the set digit can be set (corrected) by operating key S _A.

Next, FIG. 8 is a flowchart showing details of the above-mentioned time measurement process. In the figure, first step
c ₁ , the current date (month, day, day of the week, etc.) and current time (hour,
minutes, seconds) and stores the new current date and time in the time register BT. Next, in step _c2 , it is determined whether there is a 1 second carry or not, that is, whether 1 second has elapsed since the previous time.If there is a 1 second carry, the value of the status flag P is set to "1" in step _c3. Determine whether or not.
If the value of the status flag P is "1", that is, the timer is measuring, the value of the timer operation counter S is subtracted by 1 in step _c4 , and the value of S is displayed on the display section 2 (displaying the remaining time of the timer). ). Next step
If the value of the timer operation counter S after the subtraction is not "0" in step _c5 , that is, if the timer measurement is still continuing, it is checked in step _c6 whether the value of the hexadecimal counter K is "0" or not. If the discrimination is not "0", that is, if one of the rhythm tones is selected, then in step _c7 , the tone generator 14 outputs the tone of the rhythm tone corresponding to the value of the hexadecimal counter K (electronic pop-up). (K=1), Salsa (K=2), Shuffle (K=3), Disco (K=4), Rock (K
=5)] (notification processing).

Next, in step _c8 , the mark display body 2c (ⓓ) on the display section 2 is displayed (during alarm display process). On the other hand, if the value of the hexadecimal counter K is "0" in step _c6 , that is, if no rhythm tone is selected, the sound warning process and the sound warning display process in steps _c7 and _c8 are not performed.

That is, if a rhythm sound is selected, the selected rhythm sound is sounded during timer measurement,
A mark display body 2c indicates that the rhythm sound is being sounded.
It is clearly indicated by the symbol (〓).

On the other hand, if the value of the timer operation counter S is "0" in step _c5 , that is, if the timer measurement is completed, a termination sound is generated by the alarm section 14 in step _c9 , and the value of the hexadecimal counter K is determined in step _c10 . is "0", and if the value of K is not "0", that is, if a rhythm sound is selected, the step is executed.
c At _{step 11} , it is determined whether the value of the hexadecimal counter K is "5", that is, whether lock (K=5) is selected, and if lock is selected, the value of the hexadecimal counter K is set to 1 (step c ₁₂ ), if a rhythm sound other than lock (K = 1, 2, 3, 4) is selected, add 1 to the value of hexadecimal counter K (step
_c13 ), and in step _c14 , the timer value stored in the timer storage register T is transferred to the timer operation register S.

In other words, after the rhythm sound of the electronic pop (K=5) ends, the rhythm sound of the next electronic pop (K=1) is automatically played, skipping the rhythm sound unselected state (K=0). When a rhythm sound other than lock is selected and the notification of a rhythm sound other than lock ends, the next rhythm sound is automatically selected. Then, the timer value set in the timer operation register T is automatically set.

On the other hand, if the value of the hexadecimal counter K is "0" in step _c10 , that is, the rhythm sound is not selected, the step
At step _c15 , the timer value stored in the timer operation storage register T is transferred to the timer operation register S, and at step _c16 , the status flag P is reset to "0".

In this way, if timer measurement is performed with a rhythm sound selected, the next rhythm sound will be automatically selected after the timer measurement ends, and the rhythm sound will be sounded continuously. . On the other hand, if the timer measurement is performed while no rhythm sound is selected, the timer measurement ends.

The timer value D _T outputted by No. 3 is input to the timer section 35 and stored. The timer section 35 is a circuit that subtracts the stored timer value C by 1 each time the 1-second signal a is input, and outputs the timer value C to the display switching control section 25 and the 0 detection circuit 36. The 0 detection circuit 36 is a circuit that outputs the detection signal g as an H level to the alarm signal generation circuit 31 and the judgment control section 37 when the value of the timer value C becomes 0.

Next, the judgment control section 37 determines whether the flip-flop 3
4's Q output (control signal f) and the detection signal g from the 0 detection circuit 36 are input, and when the control signal f rises (L level → H level) or the detection signal g is H level, one pulse gate is input. control signal h
This circuit outputs a pulse signal e to open the control gate C _G and outputs a pulse signal e to the rhythm selection counter 29 when the detection signal g is at H level.

FIG. 10 is a diagram showing the internal configuration of the judgment control section 37. The control signal f output from the flip-flop 34 in FIG. 9 is input to the rise detection circuit 37a in FIG.
When detecting the rising edge of the control signal f, a outputs the pulse signal i to the OR circuit 37b. Furthermore, the 3-bit rhythm sound selection data R, R ₀ , R ₁ , R ₂ output from the rhythm selection counter 29 in FIG.
The decoder 37c decodes the value of the rhythm sound selection data R, and when the value of R is 1 to 5, it is input to the decoder 37c in Figure 0.
The outputs of _O1 to _O5 are set to H level. That is, R
When = 0, no output is made, when R = 1, the output of terminal O ₁ is output, and when R = 2, the output of terminal O ₂ is,
When R=3, the output of terminal _O3 becomes H level, when R=4, the output of terminal _O4 becomes H level, and when R=5, the output of terminal _O5 becomes H level.

The decoder 37d outputs the output (O ₁
It is an _AND- type decoder which receives as input the detection signal g output from the 0 detection circuit 36 and the detection signal g output from the 0 detection circuit 36, and when the detection signal g is at H level, the gates G ₆ to _{G 10} are all open. At this time, the output of the decoder 37c
If any of O ₁ to _{O 5} is at H level,
Gates G ₁ to _{G 5} corresponding to the outputs O ₁ to O ₅ are turned on, and pulse signals j, k,
Either l, m, or n is output. Pulse signals j to m are input to OR circuit 37b and OR circuit 37e, and pulse signal n is input to OR circuit 37b and 2-pulse generating circuit 37f. When the two-pulse generating circuit 37f receives the pulse signal n, it generates a two-pulse pulse signal p and inputs it to the OR circuit 37e. That is, at the rising edge of the control signal f or when the detection signal g is at H level and the value of the rhythm sound selection data R is one of 1 to 5, the gate control signal h is applied from the OR circuit 37b to the control gate C _G. Output. Also, the detection signal g is H
level and the value of rhythm sound selection data R is 1 to 5
When either of these is the case, the OR circuit 37e outputs the pulse signal e (however, when the value of the rhythm sound selection data R is 5, the pulse signal e becomes a 2-pulse signal).

Next, the operation of the second embodiment configured as above will be explained with reference to FIGS. 9 and 10. In addition, please also refer to the above-mentioned FIGS. 4 and 5.

First, at the time of initial setting, the Q outputs of the flip-flops 26 and 34 are at L level, and the rhythm selection counter 29 and timer section 35 do not output data.

Therefore, the output of the flip-flop 26 (control signal d) is at H level, and the display switching control section 25 displays the time data B output from the counting circuit 24 on the display section 22, that is, the current date (month, month,
day, day of the week) and the current time (hour, minute, second) are displayed (time display mode: see Figure 4a).

In this state, when key S ₁ is operated, the Q output of the flip-flop 26 is inverted to H level, the output (control signal d) is inverted to L level, and the display switching control unit 25 changes the display of the timer unit 35 instead of displaying the time data B. The timer time data C to be output is displayed on the display unit 22 (rhythm sound selection mode: see FIG. 5a).

In this state, by operating the key _S2 , the output of the AND gate 28 is sent to the timer time storage section 33, and the value of the timer value _DT can be set.

Next, when the key S _B is operated, the output of the AND gate 27 becomes H level, and the value of the rhythm sound data R stored in the rhythm selection counter 29 is added by 1 to become "1". The mark display body 2b corresponding to the E.POP (electronic pop-up) lights up (see FIG. 5d). From then on, every time key S _B is operated, the output of AND gate 27 rises (from L level to H level).
The value of the rhythm sound selection data R stored in the rhythm selection counter 29 is incremented by 1, and under the control of the display switching control circuit 25, the position of the illuminated mark display body 2b is sequentially changed to SALSA,
SHUFFLE, DISCO,
Move to the position indicating ROCK (see Figure 5 e-h). Further, the rhythm sound selection data R output from the rhythm selection counter 29 is also input to the rhythm sound data storage section 30. Since the rhythm sound selection counter 29 is a hexadecimal counter, 0 is stored next to R=5, so if you operate key S _B after ROCK (R=5) is selected, the unselected (R
=0), and all mark display bodies 2b are turned off.

In this way, after switching from time display mode to rhythm sound selection mode by operating key _S1 ,
By operating S _B , it is possible to select a desired rhythm sound to be sounded during timer measurement.

Furthermore, when the key S _A is operated, the Q output of the flip-flop 34 becomes H level, and as described above, the gate control signal h is output from the judgment control section 37, and the timer value output from the timer time storage section 33 is
_DT is input to and stored in the timer section 35, and the stored timer value C is displayed on the display section 22 via the display switching control section 25.

Further, when the control signal f becomes H level, the rhythm sound data D R corresponding to the rhythm sound selection data _R is transmitted from the rhythm sound data storage section 30 to the alarm signal generation circuit 3.
1, the alarm signal generation circuit 31 generates a rhythm sound signal S _R corresponding to the rhythm sound data D _R , and the rhythm sound is outputted via the audio output circuit 32. Further, when the control signal f becomes H level, the 1 second signal a output from the frequency dividing circuit 23 is input to the timer section 35, and the timer value C stored in the timer section 35 is subtracted every time the 1 second signal a is input. Ru. The value of the timer value C is displayed on the display section 22 via the display switching control section 25. Then, when the timer measurement ends and the value of the timer value C becomes "0", the 0 detection circuit 36
The detection signal g becomes H level and is output to the alarm signal generation circuit 31, and the output of the rhythm sound is stopped. At the same time, a buzzer sound signal is output from the audio output circuit 32, and the buzzer sound is output (end sound). output).

The control unit 3 determines that the detection signal g is an H level signal.
7, gates G ₆ , G ₇ , G ₈ , G ₉ , and G ₁₀ open. At this time, if the value of the rhythm sound selection data R is "1" (if the electronic pop rhythm sound is selected), the output of the terminal _O1 of the decoder 37c is at H level, so the gate
_G1 is open, and the pulse signal j is output from the decoder 37d to the OR circuits 37b and 37e. Therefore, the gate control signal h is output from the OR circuit 37b to the control gate _CG , the gate _CG is opened, and the timer value _DT stored in the timer time storage section 33 is stored in the timer section 35. The timer value C stored in the timer section 35 is displayed on the display section 22 via the display switching control section 25 and is also output to the 0 detection circuit 36, and the detection signal g output from the 0 detection circuit 36 is at L level. Become. For this reason,
The gates G ₆ to G ₁₀ of the decoder 37d are closed again. On the other hand, the OR circuit 37e outputs the pulse signal e to the rhythm selection counter 29, and the value of the rhythm sound selection data R stored in the rhythm selection counter 29 is added by 1 to become "2". This rhythm sound selection data R (=2) is output to the rhythm sound data storage section 30, and since the control section f is at the H level, the salsa rhythm sound data D _R corresponding to the rhythm sound selection data R (=2) is It is output to the alarm signal generation circuit 31. The salsa rhythm sound is played until the timer value C stored in the timer section 35 becomes "0" and the detection signal g output from the 0 detection circuit 36 becomes H level.

As explained above, the operation after the timer measurement ends is such that the rhythm sound data R stored in the rhythm selection counter 29 has a value of 2 to 4 (shuffle to disco).
The same is true in the case where the timer measurement ends, the next rhythm sound is automatically selected, and the timer operation and the next rhythm sound start again.

On the other hand, when the timer measurement based on the sound of the lock (rhythm sound data R=5) is completed, the detection signal g output from the 0 detection circuit 36 becomes H level as described above, and both the gates G ₅ and G ₁₀ of the decoder 37d are activated. Since it is open, the signal n is input to the two-pulse generating circuit 37f, and the two-pulse signal P is output from the two-pulse generating circuit 37f and inputted to the rhythm selection counter 29 via the OR circuit 37e. Therefore, the rhythm selection counter 29 counts twice and the value of the rhythm sound data R becomes "1". In this way, after the lock rhythm sound (R=5) ends, the unselected (R
The electronic pop rhythm sound (R=1) is selected instead of R=0).

Once the timer measurement is started by operating the key S _A , the Q output (control signal f) of the flip-flop 34 is always held at the H level during that time, so that the rhythm sound data is stored in the rhythm selection counter 29 from the rhythm sound data storage section 30. Rhythm sound data D _{R corresponding to rhythm sound selection data R} is always output to the alarm signal generation circuit 31. Therefore, each time one rhythm sound ends, the next rhythm sound is automatically selected and is sounded for a certain period of time (timer value _DT ).

In this way, when the timer is started by operating the key S _A , the rhythm sound is continuously emitted with the rhythm sound changing in units of a fixed time unless the timer measurement is stopped.

If you want to stop the timer operation, press key S _A
operate. Then, the Q of flip-flop 34
Since the output is inverted to L level, the rhythm sound data output D _R from the rhythm sound data storage section 30 is stopped, and since the 1 second signal a is no longer output from the AND gate 21, the timer value C by the timer section 35 is stopped. The subtraction is aborted. Therefore, since the detection signal g output from the 0 detection circuit 36 remains at the L level, the operation of the judgment control section 37 is also stopped.

Next, when key S ₁ is operated, flip-flop 2
Q of 6, output is inverted, Q = L level, = H
The current date and time are displayed on the display section 22 by the display switching control section 25 (time display mode: see FIG. 4a).

Also, at this time, both AND gates 27 and 28 are closed, making it impossible to set the timer time or select the rhythm sound by operating the keys S _A and S _B.

Note that the rhythm sound mentioned in this invention is not only a rhythm based on the strength and weakness of a sound consisting of a single frequency, but also
It also refers to melodic sounds made up of individual rhythms. In the first and second embodiments, there are five types of rhythm sounds that can be selected (electronic pop, salsa, shuffle, disco, and rock), but the types and number of rhythm sounds are limited to these. It is possible to make it possible to select a large number of different rhythm tones without having to do so.

Further, in the above embodiment, an example in which the present invention was applied to an electronic wristwatch was described, but the present invention can also be applied to other small electronic devices such as a small electronic computer and a portable radio.

[Effect of idea]

As explained in detail above, the present invention enables an instruction to be made as to whether or not to sound a rhythm sound when measuring with a timer. Since the next rhythm sound will be sounded, once you set the rhythm sound to sound and start the timer, several types of rhythm sounds will be automatically switched without having to operate a switch. Instead, you can concentrate on exercising. This is convenient because it allows you to know the passage of a certain amount of time by switching the type of rhythm sound.

Furthermore, since it is lightweight and small, it has excellent portability.
