[Formula] Display It is made up of the body. this

[Formula] The display body clearly indicates that the information displayed on the time display section 12 is date information, and

The display body clearly indicates that the information displayed on the time display section 12 is the alarm time. Next, the operation of the electronic timepiece configured as described above will be explained with reference to display examples shown in FIGS. 3 and 4. Therefore, FIG. 3 shows the function selection circuit 9.
This figure shows a state in which the display states of the time display section 12 and the function display section 13 are switched according to the set state of the time display section 12 and the function display section 13. First, in a normal state, the function selection circuit 9 constituted by a counter is in a reset state, and time information from the time counting circuit 3 is sent out from the display switching control circuit 6. Each of the flip-flops 24 to 30 has been reset by the end signal e outputted from the musical tone code storage section 49 at the end of the previous musical tone performance. As a result, the side output signals of each of the flip-flops 24 to 30 are applied to the AND circuit 10 via the AND circuit 32, and the gate is released. Therefore, the time information from the time counting circuit 3 sent from the display switching control circuit 6 is supplied to the decoder 11 via the AND circuit 10, decoded there, and then supplied to the time display section 12. As a result, the time display section 12 displays current time information, for example, "10:35:20" as shown in A of FIG. Next, when the function selection switch S ₂ is operated to advance the contents of the function selection circuit 9, the display switching control circuit 6 receives the date information from the date counting circuit 4 and the day of the week information from the day counter 5. It will now be sent. The date information and the day of the week information are decoded by the decoder 11 and then sent to the time display section 12.
is supplied to As a result, the time display section 12 displays the current date and day of the week information, for example, as shown in B in FIG.
“August 20th, MO (Monday)” is displayed. On the other hand, the output content of the function selection circuit 9 is
3, so in the function display section 13,
As shown in Figure 3B,

[Formula] The display body is driven to display and clearly indicates that the information displayed on the time display section 12 is date information. Further, when the function selection switch _S2 is operated to advance the contents of the function selection circuit 9, the display switching control circuit 6 starts to send alarm time information from the time alarm circuit 7. After this alarm time information is decoded, "PM, 3:00" is displayed on the time display section 12, for example, as shown in C of FIG. On the other hand, the contents of the function selection circuit 9 are supplied to the function display section 13, so that the contents of the function selection circuit 9 are displayed in the function display section 13 as shown in C in FIG.

[Formula] The display is driven to display, and the information displayed on the time display section 12 clearly indicates that it is alarm time information. When the time alarm circuit 7 detects a match between the time information of the time counter circuit 3 and the alarm time information, a one-shot pulse match signal f is sent out. At this time, when the content of the day of the week counter 5 is a count value of 0, that is, it corresponds to Sunday, a one-shot pulse output is obtained from the AND circuit 33 and is applied to the initial address generation circuit 47 via the OR circuit 40. Therefore, initial address information of the music corresponding to Sunday is obtained from the initial address generation circuit 47, and is set in the address counter 48. Then, the tone code storage section 49 is addressed based on the address information set in the address counter 48, and the song corresponding to Sunday is specified, and the first tone of the song, for example, the sound related to "Mi" is specified. Long code A, scale code B, and volume code C will be output. The tone length code A is supplied to the tone length control circuit 50, the scale code B to the decoder 51, and the volume code C to the decoder 52. For this reason,
The scale frequency signal selection circuit 54 selects "mi" from among the clock signals from the scale frequency signal generation circuit 53.
selectively outputs a clock signal with a frequency of , and supplies it to the volume control circuit 55. Then, the volume control circuit 55 performs volume control according to the contents of the decoder 52, and provides this output to the speaker 56. Therefore, the first musical tone "mi" is pronounced. This first musical tone is controlled by the tone length control circuit 50 until a predetermined time corresponding to the tone length code A has elapsed.
pronounced. When an output is obtained from the tone length control circuit 50, the count value of the address counter 48 is incremented by +1, and the address in the tone code storage section 49 is converted to the next address. As a result, the tone code storage unit 49 stores the tone length code A for the second tone composing the music, for example, "G",
Output scale code B and volume code C. Therefore, the musical tone "G" is produced from the speaker 56 at a predetermined volume. Thereafter, similar operations are repeated to play the music corresponding to Sunday. Therefore, the content of the day of the week counter 5 is +1 to the count value.
When the alarm time is detected and the coincidence signal f is obtained from the time alarm circuit 7, an initial address is generated via the OR circuit 41 by the output of the AND circuit 34. is applied to circuit 47. As a result, the initial address information of the music corresponding to Monday is obtained from the initial address generation circuit 47, and is set in the address counter 48. Therefore, at the alarm time on Monday, a different piece of music is played than the piece played on Sunday. Similarly, at the alarm time on Tuesday, Wednesday, . . . Saturday, music unique to that day of the week is generated. Therefore, you can tell what day of the week it is by listening to the music being played. FIG. 4 shows a state in which the display state of the time display section 13 is changed in response to the operation of the demonstration switch _S3 . Time display section 12
, when the normal time ``10:36:00'' is displayed, if you want to listen to music played on each day of the week, operate the demonstration switch _S3 . Therefore, the contents of the music selection circuit 15 are
For example, when the count value is 2, if the demonstration switch _S3 is operated, the content of the music selection circuit 15 is set to the count value 3, and after the delay time of the delay circuit 16 has elapsed,
An output is obtained from the delay circuit 16, and a one-shot pulse output from the AND circuit 20 is obtained from the OR circuit 4.
3 to the initial address generation circuit 47. The initial address generation circuit 47 outputs the initial address of the music corresponding to Wednesday and supplies it to the address counter 48. As a result, the music corresponding to Wednesday is addressed in the musical tone code storage section 49, and the first musical tone code composing that musical piece is read out. Therefore, the speaker 56 generates music corresponding to Wednesday. At the same time, the output signal of the AND circuit 20 sets the corresponding flip-flop 27, so that the Q side output signal of the flip-flop 27 is applied to the decoder 11. Therefore, the decoder 11 is the flip-flop 2.
The day of the week information for Wednesday is output based on the Q side output signal of No. 7 and is supplied to the time display section 12. Therefore, "WE" indicating Wednesday is displayed on the time display section 12, as shown in B of FIG. On the other hand, when the performance of the music corresponding to Wednesday ends, the musical tone code storage section 49 outputs an end signal e, which resets all the flip-flops 24 to 30 via the OR circuit 31. As a result, the time display section 12 displays the normal time, for example, "10:36:20" as shown in C in FIG.
is displayed. Also, in this state, the demonstration switch _S3 is operated again. By operating this switch _S3 , a one-shot pulse is obtained, the contents of the music selection circuit 15 are incremented to the count value 4, and the contents of the address counter 48 are reset. Then, after the delay time of the delay circuit 16 has elapsed,
The output of the AND circuit 21 is obtained and applied to the initial address generation circuit 47 via the OR circuit 42.
Therefore, address information corresponding to the output signal of the OR circuit 42 is output from the initial address generation circuit 47 and set in the address counter 48. As a result, the musical piece corresponding to Thursday is specified in the musical tone code storage section 49, and the first musical tone code that composes the musical piece is read out. Therefore, the speaker 56 produces music corresponding to Thursday. On the other hand, at the same time as the music is sounded, the output signal of the AND circuit 21 sets the corresponding flip-flop 28, so that the Q-side output signal of the flip-flop 28 is applied to the decoder 11. Then, the decoder 11 outputs day-of-the-week information for Thursday based on the Q-side output signal of the flip-flop 28, and supplies it to the time display section 12. Therefore, "TH", which clearly indicates Thursday, is displayed on the time display section 12, as shown in D in FIG. In this manner, by operating the demonstration switch _S3 , the music corresponding to the day of the week is generated, and at the same time, the day of the week information of the music that is being generated is displayed. Therefore, by looking at this display, it is possible to know on what day of the week and at what alarm time the music being generated is being emitted. If the demonstration switch _S3 is operated while listening to the song corresponding to Thursday, the contents of the song selection circuit 15 are incremented, and the address counter 48 and each flip-flop 24 to 30 are incremented. is reset. Therefore, the generation of music stops midway, and the day of the week display is also turned off. Then, since the output of the AND circuit 22 is obtained, the speaker 5
From 6 onwards, music corresponding to Friday is generated, and at the same time, the day of the week indicating Friday is displayed on the time display section 12. Furthermore, if the demonstration switch _S3 is operated again while the music corresponding to Friday is being generated, the music corresponding to Saturday will be generated and the day of the week will be displayed to clearly indicate Saturday. In this way, each time the demonstration switch _S3 is operated, the music being played and the day of the week display are switched one after another. Therefore,
You can listen to seven types of songs in a short period of time, and you can also know on what days of the week those songs will be played. In the above embodiment, the music being generated is changed each time the demonstration switch is operated, but this invention is not limited to this. Therefore, seven types of music may be continuously generated. In this case, each time a song is played continuously, the day of the week display corresponding to the song is also sequentially switched. Furthermore, this invention can be widely applied to electronic watches with calculation functions and the like. Further, in the above embodiment, music is generated as the notification sound for the time alarm, but the present invention can also be applied to an arrangement in which music is generated as the notification sound for the time signal. As explained in detail above, this invention is equipped with a music generation function that generates a different music for each day of the week, and it is possible to preview the music for each day of the week by external operation. At this time, the day of the week is displayed to clearly indicate which day of the week the song is being played.
You can memorize the songs that are played every day of the week in a very natural way. Therefore, you can definitely know which day of the week it is just by listening to the music that signals the alarm time.
