Description

[Detailed Description of the Invention] The present invention relates to a pointer-type clock equipped with alarm functions such as an alarm and a time signal. In the case of an alarm clock, the alarm function sounds when the hour hand matches the guide hand, and in the case of a time signal clock, the alarm function sounds when the minute hand points to zero minutes. It is necessary to mount the watch with the guide hand and hour hand aligned accurately, or the minute hand with the zero minute mark on the dial. For this reason, in the past, it was necessary for a person to slowly rotate the gear train to which the pointer was to be attached by adjusting the needles, find the point of sound, and then attach the pointer. Furthermore, the accuracy of the start of the sound was extremely poor. The purpose of this invention is to eliminate manual labor and improve accuracy. The gist of the invention is to provide a control circuit that inputs the operation of a switch that starts an alarm in conjunction with the pointer section and stops the motor, and a construction section that determines whether or not the control circuit is enabled. It is characterized by The point of sound is detected by the watch itself, and the motor is stopped based on the detection signal, so that a person can safely attach the hands while the motor is stopped. As a result, accuracy is improved, and there is no need for a person to search for the point of sound by adjusting the needles.

The present invention will be explained using drawings. FIG. 1 is a block diagram showing a first embodiment of the present invention. 1 is a motor section, 2 is a motor control section, and 3 is a motor. 4 is a pointer section driven by the motor 3. Reference numeral 5 denotes a switch unit which is interlocked with the pointer unit 4 via a wheel train, and 6 is a switch. Reference numeral 7 denotes an alarm unit which generates sound based on the operation of the switch 6. Reference numeral 8 is an operation unit, and by performing operation 9, the switch 6 is activated.
The structure is such that the operation of the motor 1 can be transmitted to the motor section 1. The motor unit 1 receives this and stops the motor 3. There are several ways to stop the motor 3, such as stopping crystal oscillation and shorting the motor coil to ground. FIG. 2 shows an embodiment of the operating section of FIG. Reference numeral 10 is a switch pad, and a signal indicated by an arrow 11 is inputted from the switch 6. 12 is a stop pad. Reference numeral 13 indicates a pile of solder, and when the solder 13 is piled up across the switch pad 10 and the stop pad 12, the operation of the switch 6 is transmitted in the direction of the arrow 14, and the motor 3 is stopped. Pointers are attached in this stopped state. Next, solder 13 is removed and solder 15 is applied. The switch pad 10 and the alarm pad 12' are connected, the motor 3 starts operating, and if the switch 6 is operated, the clock is transmitted in the direction of the arrow 16 and an alarm sounds, forming a normal clock. The relationship between the switch pad 10, the stop pad 12, and the solder 13 corresponds to the control means of the present invention, and the relationship between the switch pad 10, the stop pad 12, and the alarm pad 1 corresponds to the control means of the present invention.
The relationship 2' corresponds to the switching means. FIG. 3 shows a circuit diagram of a second embodiment of the invention. 17 is a crystal, 18 is an oscillation frequency dividing circuit 19 is a drive circuit, 3
is a motor, and these constitute motor 1. 4 is a pointer section, 5 is a switch section, and 6 is a switch that operates in conjunction with the pointer section 4, which is a guide switch in the case of an alarm clock and a time signal switch in the case of a time signal clock. 7 is the alarm part, and gate 20
and a sound generator 21. 8 indicates an operation section. 22 is a power-on clear circuit, and 23 is a flip-flop (hereinafter abbreviated as FF). In the state where the current time is normally displayed, when the power is turned on, the FF 23 specifies the AND gate 24 to pass the signal from the oscillation frequency dividing circuit 18, and puts the AND gate 20 of the alarm section 7 in a standby state. When the pointer section 4 rotates and the switch 6 operates at a set time, the signal passes through an AND gate 20 and is set to sound a sound generator 21 in synchronization with a signal from an oscillation frequency dividing circuit 18. . 25 is an operation terminal, 26 is an operation signal, and 27 is a differential circuit. Operation signal 26
is connected to the operating terminal 25 and the operating terminal 25 is in one potential state (+ potential in FIG. 3), the FF23
is inverted, selects the AND gate 28, and closes the AND gate 24. In this state, when the pointer section 4 moves and the switch 6 operates, the output of the AND gate 28 passes through the line 29 to reset the drive circuit 19 and stop the motor 3. The motor 3 remains stopped from the moment the switch 6 operates. Since AND gate 24 is closed, sound generator 2
1 never rings. If you have an alarm clock, install it in this position so that the guide hand and hour and minute hands are aligned. If it is a time signal watch, it can be installed in this position so that the hour and minute hands are aligned with the zero minute mark on the dial. To return to a normal watch after setting the hands, use the power-on clear circuit 2.
2, flip FF23 and connect operation terminal 2.
5 may be set as the other potential. Generally, the operation is performed by moving the dry cell vertically with your finger to turn the connection between the dry cell and the battery plate OFF and ON. With such a configuration, it is safe because even if the power supply is shattered due to vibration during use, the AND gate 24 is always selected. Alternatively, a dedicated push button may be provided separately for the recovery operation.

The line 27' is provided so that when an operation is performed and preparations are made to stop, the sound generator 21 emits, for example, a confirmation sound such as a pop to notify that the operation has been completed.

FIG. 4 shows an example of a structure related to the operation signal 26 of FIG. 30 is a main plate, 31 is a pointer shaft, and 32 is a cover. 33 is FF23, drive circuit 1
It is a circuit board equipped with 9 etc. 25 is a pad corresponding to an operation terminal, and 26 is a ground pad. 34 is a contact needle, and 35 is a connecting wire.
36 is a hole opened opposite to the pads 25 and 26. The contact needle 34 is lowered in the direction of arrows 26-1 and 26-2, passes through the hole 36, and hits the pads 25 and 26. Then, the differentiator circuit 27 in Fig. 3 will operate.
FF23 selects AND gate 28 and switches 6
If this occurs, prepare to stop motor 3.

The needle attachment work according to the present invention is as follows.

(1) The watch is operating in the state before switch 6 operates.

(2) Prepare by operating the operation section 8.

(3) If the clock turns and switch 6 is turned on, the clock will stop.

(4) Attach pointers.

(5) Start the clock by moving the battery etc.

According to the present invention, when attaching a guide pointer or a minute hand for time reporting in order to find the point of sound on the watch itself, there is no need for a person to turn the gear train to find the point of sound. It does not take much time to install it, and it requires a very delicate operation by a person to turn the gear train and find the point of sound, and by the time you hear the chirp sound at the point of sound, the needle has already been at the position for several minutes. There is no need to be in an advanced state, and the accuracy of pointer attachment is improved. As a result, a pointer watch with an alarm that does not cause ringing errors can be easily provided, which is not only highly effective in attaching the pointer to a completed watch, but also achieves great effects when selling modules.
