Description

[Detailed description of the invention]

The present invention relates to improvements in analog timepieces with hands and analog/digital composite timepieces. More specifically, we propose a method for improving the analog display part of analog watches with hand displays and composite watches, thereby further increasing the product value. Conventionally, in so-called digital watches that use liquid crystal, a part of the liquid crystal is used and combined with the parting plate of the watch. By combining the iris part 2, for example, by making the iris part 2 blink every second, it was possible to propose a clock with an interesting animal animation style. In a digital watch that uses a liquid crystal for display, once the placement of electrodes etc. is determined, blinking of the iris 2 can be done by adding a frequency division signal to the circuit, and in particular, it can be used as a time display. This can be easily achieved without disrupting the hours or minutes. An example of an analog watch with a hand display is a mechanical watch that uses a mainspring, such as a mechanical watch that has some kind of hand attached to the shaft of the pallet handle, so that the reciprocating movement of the pallet wheel creates an interesting reciprocating movement of the hands. As shown in the figure, the mouse 3 is attached to the second hand section 3.
a, the second hand rotates at a constant speed, and an animation is displayed together with the cat picture 5 on the dial 4. However, these methods lack dynamic and interesting animation, and are just a picture of a second hand. The present invention aims to improve this point in analog display watches, especially electronic watches. As one embodiment of the present invention, Fig. 3 is a block diagram, Fig. 4 is a diagram showing the movement of the second hand, Fig. 5 is an electronic circuit diagram, Fig. 6 is a timing chart, and Fig. 7 is an implementation as a clock. Give an example. In FIG. 3, the vibration of a time standard 6 made of a crystal oscillator or the like is divided into a signal every second by a frequency dividing circuit 7 made of a MOS IC or the like, and the waveform is shaped by a motor drive circuit 8 to drive a motor 9. The rotation is transmitted through the wheel train 10, and the rotation is displayed by a hand display 11 consisting of hour, minute, and second hands. A memory circuit 13 is used that counts a part of the signal from the frequency divider circuit 7 using a frequency divider circuit or a counter. The signal from the memory circuit 13 is input to the motor drive circuit 8. Moreover, by providing the external operation member 12,
It is also possible to control the memory circuit 13, but this is not necessary. Before explaining the electronic circuit, FIG. 4 shows the movement of the second hand realized by this method. The horizontal axis represents the true time (time), and the vertical axis represents the current time indicated by the second hand. A solid line 14 is the actual movement of the second hand. Period B is, for example, in the case of a watch that moves every second (it is possible to set the interval of the second hand movement, which has a relatively short period, if necessary).
This is a fast-forward period, and period C is a period during which the movement of the second hand is stopped. Repeat the same thing with D. Period E is a normal hand movement period. Here, the hand moves in steps every second. Next, there is a second hand abnormal movement period of period D. In other words, the second hand was not moving in a constant manner, but rather irregularly. This will be explained using circuit examples shown in FIGS. 5 and 6. In addition, the time standard 6, frequency dividing circuit 7, and
The memory circuit 13, drive circuit 8, and motor 36 each correspond to the block diagram in FIG. The crystal oscillator 21 vibrates at 32 KHz, and the frequency dividing circuit 22 outputs two frequency-divided signals, a 128 Hz signal a and a 4 Hz signal b. Here, frequency dividing circuits 23, 24, 25, and 26 are used as memory circuits for simple processing. That is, 1/4Hz signal e, 1/8Hz
AND gate 27 with signal f and 1/32Hz signal 26
It outputs a signal h. During the period A during which the 1/32Hz signal g is low and not output, the 1/2Hz signal d for driving the motor normally passes through the AND gate 28 and is ORed.
D type flip-flop 31 through gate 30
The signal delayed by 1/128Hz and the gate 32,
A motor drive output j is obtained by a well-known motor signal waveform shaping circuit 33 and inverters 34 and 35, and a rotor 36 made of a permanent magnet is rotated. The period D during which the 1/32Hz signal g is High is:
The AND gate 28 does not output a signal to move the motor every second, and the signal h of the gate 27 is b, ef,
The g signals are combined to form the h signal. Therefore, only during period B, a 4Hz signal (for 8 steps) serving as a fast forward signal is output, and during the remaining period C, a stop signal is output, and the motor does not move and the second hand does not move. This fast forward signal and stop signal are combined to form an abnormal hand movement display signal. Next, when an external operating member, for example, a switch 12 that is linked to a winding stem (not shown), is grounded to +, the frequency dividing circuits 24, 25, and 26 are reset, and e, f, and g are not output, and only the d signal is output. can pass through gate 29, so the hands will move in the same way as normal using the d signal that has passed through OR gate 30.
The gates 28 and 29 constitute a selection circuit 40 that is linked to an external operating member. By controlling such electric signals, the movement of the second hand of the clock shown in Fig. 7 is controlled as shown in Fig. 6.

[Table] is repeated. The signal of period B is a fast forward signal,
When the period C signal is used as a stop signal, the driving cycle of the hands when the fast forward signal and stop signal are combined is the driving cycle of the hands when driven by the normal time reference signal (signal for hand movement every second). Since the setting is the same as that of the pointer, the pointer does not cause any indication error as a whole. Therefore, the mouse 3a attached to the second hand 3 in Fig. 7 runs away quickly as if being chased by the cat 5 drawn on the dial 4, stops and looks at the situation, stops again, and returns to its normal speed. It has become possible to display such dynamic hand movement. Also, to make the hands move every second, use the external operation member.
All you have to do is operate the winding stem 37. In the present invention, the motor has been described in terms of hand movement that includes many repetitions of fast-forwarding and stopping, but it is possible to change the count constant or division ratio of the memory circuit by an animation picture drawn on the dial. It is controlled by a well-known electronic circuit, and the movement speed of the second hand can be changed freely. Also, even if the second hand does not have a rat attached to it, it can be a regular second hand.Furthermore, the second hand itself can be modified by considering a combination with a picture on the dial that can be seen as a baseball bat or ball. When combined with changes, a wide variety of developments are possible, and the parts that correspond to these changes can be easily made by simply changing part of the IC circuit and not replacing mechanical parts such as the wheel train. It has various features, such as being able to match the picture on the dial and adapting to changes in the specifications of the watch. As other examples, Fig. 8 shows a motor drive waveform for reversing the motor, and Fig. 9 shows an example of changing the hand movement using this reversing motor.
For example, in Fig. 7, the mouse second hand runs away, returns, and stops, making it possible to propose an interesting and dynamic clock especially for young children.
