BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece clock that emits different bell sounds at half hour and half hour.

[0002]

2. Description of the Related Art A form related to time reporting other than an alarm sound is
Some sound only on the hour and some sound on the hour and half. The time signal sounds include an electronic sound using an electronic circuit such as a melody IC and a bell sound obtained by striking a metal sounding body such as a bell or a bell (hereinafter simply referred to as "sounding body").

[0003]

The bell sound has a clear tone and is very comfortable to listen to. However, there is a problem that the striking mechanism becomes complicated when trying to sound with different sounds for the hour and the half hour.

Therefore, without changing the conventional striking mechanism,
It is conceivable to obtain different sounds or tones by controlling the driving of the striking motor. However, in this case, means for automatically controlling the driving of the striking motor must be devised. The present invention has been made from the above viewpoint.

[0005]

[Means for Solving the Problems] That is, the timepiece timepiece of the present invention comprises a striking mechanism for rotating the striking motor forward and backward to generate different striking sounds, and a 30-hour hour for every hour and half an hour. , A drive contact mechanism for generating a motor drive start signal for starting the driving of the striking mechanism, a time digit time code corresponding to the pointer time and a specific code different from each time code is formed between all the time codes. When a time code is detected from the time code plate based on the time code plate and the motor drive start signal, one of the forward rotation signal and the reverse rotation signal of the striking motor is output to output the specific code. A forward / reverse rotation discrimination circuit that outputs the other signal when detected, a motor drive start signal of the drive contact mechanism, and an output signal of the forward / reverse rotation discrimination circuit are input and a drive signal is output to the striking motor. Striking bell A configuration driver circuit, comprising a.

[0006]

[Operation] Normally, the striking motor is stopped. The time code is detected when the positional relationship between the time code plate and the sliding contact plate is immediately before any one of the hours from 1 o'clock to 12 o'clock, and when this detection signal is input to the forward / reverse rotation determination circuit, the normal / reverse rotation is detected. From the reverse rotation determination circuit, a normal driving signal for the bell-striking motor is output to the striking mechanism control circuit. When the hour comes thereafter, the drive contact mechanism outputs a motor drive start signal to the striking mechanism control circuit. As a result, the striking motor is rotated in the forward direction, and the hourly striking sound is generated.

When the positional relationship between the time code plate and the sliding contact plate reaches a specific code detection position, a forward / reverse rotation discriminating circuit outputs a backward driving motor for striking to the striking mechanism control circuit. At half hour thereafter, a motor drive start signal is output to the striking mechanism control circuit, and the striking motor is rotated in the reverse direction to generate a half hour belling sound.

FIG. 10 is an enlarged cross-sectional view of a main part, in which 80 is a lower plate, 81 is a circuit board, 82 is an intermediate plate, 83 is an hour wheel, and 8
Reference numeral 4 indicates a minute hand wheel, and 85 indicates a second hand wheel.

Reference numeral 86 is a drive contact mechanism for generating a motor drive start signal S1 for driving the bell-swing motor 1, and a cam wheel 89 having a hour cam projection 87 and a half hour cam projection 88 has a minute hand. The contact plate 90 is integrally mounted on the vehicle 84, and the contact plate 90 faces the cam wheel 89 at half hour and half hour.

The contact plate 90 engages with the cam projections 87, 88 and is elastically deformed, and the projections 87, 8 at half hour or half hour.
When the engagement with 8 is released, it elastically returns to contact with a fixed contact (not shown). As a result, the start signal S1 is generated. As shown in FIG. 1, the start signal S1 is normally set to H level, and becomes L level because the drive contact mechanism 86 is closed at half hour or half hour. When the start signal S1 of L level is input to the striking mechanism control circuit 2, the striking motor 1 starts rotating.

Reference numeral 91 is a position detection wheel which is rotatably supported between the lower plate 80 and the circuit board 81, meshes with the hour hand wheel 83, and rotates in synchronization with the hour hand wheel 83. The position detection wheel 91 has five sliding contacts 92a, 92b, 9 as shown in FIG.
A sliding contact plate 92, in which 2c, 92d, and 92e are linearly arranged, is integrally rotatable.

On the other hand, the circuit board 81 is provided with the code plate 3 shown in FIG. The code plate 3 is composed of a circular conductive portion E and fan-shaped conductive portions A, B, C and D which are concentric with the conductive portion E and are provided on different radii.

The sliding contacts 92a to 92d are code plates 3
The sliding contact 92e and the conductive portion E are always in conduction with the conductive portions A to D of the sliding contact 92e. The conductive portion E is always set to the H level, and the sliding contacts 92a to 92d change the output signals a to d from the conductive portions A to D of the code plate 3 from the L level to the H level.

The conductive portions A to D are radially divided into 24, and the radial region is, as shown in FIG. 13, a time region T1 to T12 representing the hour on the hour, that is, a half-hour period. The time areas M1 to M12 are alternately arranged.

Therefore, when the sliding contacts 92a to 92d are located in the time regions T1 to T12 of the code plate 3, the conductive portions A to
As shown in FIG. 14, D outputs output signals a to d corresponding to the numerical values of 1 to 12 according to the binary system. In addition, sliding contact 9
When 2a to 92d are located in the half-hour regions M1 to M12, the sliding contacts 92a to 92d do not engage with the conductive parts A to D, so that the conductive parts A to D all output H level signals a to d.

The striking motor 1 is set to rotate normally when the output signal S3 from the forward / reverse rotation determining circuit 4 is at L level and reverse when it is at H level.
The reverse rotation technique requires signal processing that specifies the rotation direction. This will be described with reference to FIG.

Output signals a to d from the code plate 3 are input to the forward / reverse rotation discriminating circuit 4 and the striking mechanism control circuit 2. The forward / reverse rotation discriminating circuit 4 is exclusive with the NOR gate 5
It is composed of an OR gate 6, and the output signals a to d are input to the NOR gate 5. Output signal S2 of the NOR gate 5
The start signal S1 of the drive contact mechanism 86 is input to the exclusive OR gate 6.

The striking mechanism control circuit 2 detects the discrimination signal S3 of the forward / reverse rotation discriminating circuit 4, the start signal S1, the output signals a to d from the code plate 3 and the number of times the striking mechanism 100 strikes. The number-of-bells signal S4 from the number-of-times detector 7 is input.

Next, the operation will be described. Immediately before the hour before 1 o'clock to 12 o'clock, due to the engagement state of the sliding contacts 92a to 92d and the conductive portions A to D, the NOR gate 4 has the state shown in FIG.
The output signals a to d corresponding to 1 o'clock to 12 o'clock shown in are input, and the output signal S2 of the NOR gate 5 is all at the L level. After that, when the hour comes, the drive contact mechanism 86 is closed, so that the start signal S1 becomes L level and the determination signal S3 of the exclusive or gate 6 becomes L level. As a result, the striking motor 1 is set to rotate in the clockwise direction, whereby the striking sounds of the striking mechanism 100 can be simultaneously struck.

When the sliding contacts 92a to 92d are in the positions where they do not engage with the conductive portions A to D, the output signals a to d are all H level.
The output signal S2 becomes L level. After that, when it is half an hour, the drive contact mechanism 86 is closed, and when the start signal S1 becomes L level, the determination signal S3 of the exclusive OR gate 6 becomes H level. As a result, the striking motor 1 is set to rotate in the counterclockwise direction, whereby the striking sound of the striking mechanism 100 can be performed in multiple steps (chinching).

The striking mechanism control circuit 2 determines 1 to 12 times on the hour and 1 on the half hour based on the output signals a to d from the code plate 3 and the number of times of striking S4 from the number of times of striking detector 7. It controls the sound of beating the bells once.

[0039]

According to the present invention, it is possible to provide a timepiece clock that automatically produces different bell sounds at the hour and the half hour.
