Abstract

PURPOSE:To eliminate unnaturalness due to no time casting and allow a time- casting tone to be listened to immediately when the time casing tone is desired by generating a time casting tone immediately when the timepiece is adjusted on the time by turning hands manually. CONSTITUTION:A timer circuit 6 generates an output ''1'' 59min after the start of clocking, and when a switch 5 is closed a little bit before on the time, a pulse from a one-shot pulse generating circuit 13 is passed through a gate circuit 8 to set a flip-flop circuit and a gate circuit 10 is opened. A 1min signal from A frequency dividing circuit 2 is supplied to the gate circuit 10 and the 1min signal on the time is passed through the gate circuit 10 to obtain a time-casting start signal, which is passed through a gate circuit 11 to operate a time signal circuit 14, casting the time. Here, if the switch 5 is closed by rotating the hands manually before the timer circuit 6 reset with the trailing edge of the pulse from the one- shot pulse generating circuit 13 clocks 59min, the pulse from the one-shot pulse generator 13 is passed through a gate circuit 9 to operate the time signal circuit 14, which casts the time.

However, according to this, even if the hands are turned manually to set the hour, the time will not be announced unless a one-minute signal is generated. Even when the user turns the hand and hears the sound of the hour contact point closing with the curtain, the time is not signaled, giving an extremely unnatural impression. Also, when listening to the time signal tone at a store or the like and calling a friend, it was inconvenient that the time signal could not be set immediately.

Then, just before the hour, when the switch 5 is closed as shown in Fig. 2A, a pulse shown in Fig. 2H is generated from the one-shot pulse generating circuit 13, which passes through the gate circuit 8 as shown in Fig. 2. 7
The lip-flop circuit 7 is set and the gate circuit 10 is opened. The gate circuit 10 includes the frequency dividing circuit 2 to 1 in FIG. 2G.
After supplying the minute signal, the one-minute signal on the hour passes through the gate circuit 10 as shown in Fig. 2 H and becomes the time signal start signal, which is further transmitted to the gate circuit as shown in Fig. 2 F. 11, the time signal circuit 14 operates, and the hour is announced. For example, if it is 7 o'clock, the 7th time alarm sound is generated and the time is announced.

・Things that generate output from etc. may also be used. However, in this case, even if you manually turn the hand to set iE for the 2nd, 6th, and 4th minutes of the hour or C, the time will not be announced immediately, but will be synchronized with the 1-minute signal. An announcement will be made at the time.
