DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative clock that drives a decorative body by playing music at the hour or the like.

[0002]

2. Description of the Related Art Today, a decorative body clock is used to play music at an hour or the like, open a door to make a decorative body such as a doll appear, and give the appearing doll a movement such as rocking the doll. There are a clock, a clock, and a clock that swing or rotate a decoration as a decorative body attached to the vicinity of the dial, such as around the dial, in accordance with music.

In this decorative body timepiece, in order to drive the decorative body, a mechanical mechanism incorporating a DC motor is often used, and the mechanical mechanism uses various link mechanisms and cam mechanisms to rotate the motor forward and reverse. Reciprocating movement of decorations and doors,
In order to play music, it is common practice to use a melody IC to generate sound from a speaker and control the motor and the melody IC using a microcomputer.

For example, in a decorative clock in which a stage is opened by opening a door, as shown in FIG. 6, music is divided into an opening tune, a main tune, and an ending tune, and the door is opened in accordance with the opening tune and the main tune is opened. In many cases, the decorative body is moved according to the song, and the door is closed according to the ending song. In addition, in the case of operating a movable part as a decorative body attached around the dial, etc., simply play music and give movement to the decorative body, and the stationary position of the decorative body is fixed. With regard to the above, the movable unit is stopped at a predetermined position by using a position detector such as a limit switch and stopping the motor for driving the movable unit by a signal input from the position detector after a predetermined time has elapsed.

[0005]

As described above, a decorative clock in which music is played by the melody IC, the door is opened by the motor for driving the movable portion and the stage appears, and the movable portion such as the door or the decorative body is provided. When the battery is used as a power source for driving, load fluctuations occur due to changes over time such as battery consumption and mechanical resistance of the link mechanism, and the rotational speed of the motor is changed due to changes over time such as battery consumption and load fluctuations. Fluctuates over time, and the time required to open and close the door changes, so that the closing of the door and the end of the ending song could not be matched.

[0006] When the movable part, which is a decorative body arranged near the dial, is driven at every hour or the like, since the decorative body is always visible, the movable part is always kept stationary at a fixed position. Is often requested. However, the rotation speed of the motor for driving the decorative body also fluctuates due to the consumption of the battery and the change in the mechanical resistance, and the end of the operation of the decorative body and the end of the music could not be matched.

[0007] Furthermore, when a plurality of music pieces are played in accordance with the movement of the decorative body, the end of each music piece cannot be matched with the movement of the decorative body. Also, the melody IC using a CR oscillator also changes its oscillation frequency due to fluctuations in the power supply voltage, and the playing time may change even for the same song. However, there is a disadvantage that it is more difficult to match the end of the operation of the door or the ornament with the end of the music. The melody IC and the power supply of the microcomputer for controlling the melody IC and the mechanism, and the door and the ornament of the mechanism. When a different power supply is used as the power supply for the motor for driving the door or the like, the number of cases where the operation end of the door or the decorative body and the end of the music do not coincide with each other further increases, and the operation end of the door or the decorative body is further increased. There is a disadvantage that it is more difficult to match the end of the music.

[0008] When a plurality of melody ICs are used, when different oscillators are used for each melody IC, the end of the music may not coincide. As described above, in the decorative body clock, the decorative body, the door, or the melody IC
When operating various mechanisms such as the above, it is difficult to match the end of the operation of each mechanism as predetermined, and the stage is configured so that the inconsistency of the end of the operation is not noticeable.

The present invention eliminates such drawbacks, makes the end of a predetermined operation coincide with the end of another operation, facilitates the combination of the operations constituting the stage, and widens the range of change of the stage to decorate. The design and the like of the body clock can be further facilitated.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the first embodiment of the present invention, the completion of closing a door as a movable portion in a table clock or wall clock, which is a decorative clock, coincides with the end of music. In this embodiment, a melody IC and a microcomputer as control means of the melody IC are used as a main mechanism. As shown in FIG. 1, music is played, and a door as a slave mechanism is opened in accordance with the opening music. After the door is released, a doll or the like, which is a decorative body, performs a series of operations in accordance with the main song, and then closes the door in accordance with the ending song, thereby terminating the stage, as shown in FIG. When an hour signal is input from the hour contact 13 to the microcomputer 10, the microcomputer 10 outputs a music selection signal and a start signal to the melody IC 21 from the microcomputer 10 which is the control means of the melody IC 21 and the control circuit of the slave mechanism. , An operation signal is output to the power switch 23 of the amplifier 25 and sound is generated from the speaker 27, and a control signal is output to the mechanism mechanism 29. And controls the operation of the opening and closing and decoration of the door to.

When controlling the mechanism 29,
Detection signals from many limit switches for detecting the position of each movable part such as a door as a slave mechanism and a doll as another slave mechanism are input to the microcomputer 10 and a melody IC 21 is input.
A control mechanism that outputs a control signal from the microcomputer 10 which is the control means of the controller and also serves as the control circuit of the slave mechanism
Each of the movable unit driving motors incorporated in 29 is operated.

In this embodiment, when the melody IC 21 is driven, a stable oscillator such as a crystal oscillator or a ceramic oscillator is used, and while a busy signal or the like is input from the melody IC 21 to the microcomputer 10, a selection signal and a start signal are output. Is input to the melody IC21, the opening song is played when the door is opened, the main song of the different song is played according to the time zone according to the movement of the decorative body, and the ending song is played when the door is closed, When closing the door, delay the operation of the door opening / closing drive motor from the start of the ending music by the time difference between the playing time of the ending song and the preset time required for closing the door, and the door opening / closing drive motor. The door is closed by the detection signal from the door closing position detection limit switch from the output of the control signal that activates The time to check those storing the measurement value T2 measured by the microcomputer 10.

When the next hour signal is input or the monitor signal is input by the monitor switch 15, the door is closed after a predetermined time after a start signal for sounding an ending song as a specific music for closing the door is output. A signal is output, and this fixed time is set to match the difference between the set value T1 corresponding to the length of the ending tune when the door is closed and the measured value T2 measured last time.

As described above, in the present embodiment, the melody IC 21 as a main mechanism is operated by using a stable oscillator such as a crystal oscillator to keep the music playing time constant, and when closing the door as a slave mechanism, the door is closed. The time required to close the door is measured each time, the difference between the playing time of the song when closing the door and the time required to close the door is calculated, and the start signal of the song when closing the door and the door are closed Differentiate the output time from the control signal,
Since the control signal for closing the door is output after the output of the start signal, as shown in FIG. 1, the end of the music performance and the stop due to the closing of the door can be matched.

Also, in the above embodiment, the selection signal and the start signal are output to the melody IC 21 in accordance with the opening of the door, the driving of the decorative body, and the closing of the door, so that the tune is changed.
At the beginning of opening the door, a start signal is output to the melody IC 21. As shown in FIG. 3, one tune having a long playing time or a plurality of tunes combined in a medley style is amplified from the melody IC 21 by inputting one start signal. In this case, the time from the output of the start signal to the end of all the performances is set as the set value T1, and the start signal is calculated by the difference between the set value T1 and the measured value T2 in the same manner as described above. It suffices to output a control signal to close the door with a delay from the output of.

As described above, in the decorative body timepiece, when the movable part driving motor is operated, the measured value which is the operation time of the door whose operation end is set relative to the predetermined operation of the melody IC 21 as the main mechanism. T2 is stored, and the closing operation of the door as the slave mechanism is started before reaching the completion of the closing of the door, which is the end of the operation of the slave mechanism set corresponding to the operation of the melody IC21 as the main mechanism. The operation of the door is started before the predetermined operation of the melody IC 21 by the operation time T2 measured at the time of the previous closing operation, so that even if the operation time of the door changes over time, The closing of the door can always be completed in accordance with the end of the song.

The change in the time required to open and close the door due to a load change due to battery consumption or a change in mechanical resistance of a link mechanism or the like generally occurs on a daily or monthly basis, and forms a stage. The end of the song and the stop of the door can always be matched by adjusting to the measured value T2 of the previous measurement with almost no change in one-hour units.

The measurement of the time required to close the door is not limited to the case where the operation time immediately before is always measured by measuring once for every several stages formed, but is always used for the music. The end and the stop of the door can always be matched. Further, in the above embodiment, the measurement is performed when the door is closed, but from when the control signal for opening the door is output to when the detection signal from the open position detection limit switch is input when the door is opened. Is measured to obtain a measured value T2,
The difference between the measured value T2 and the set value T1 may be obtained.

In this case as well, the time required to open the door and the time required to close the door are generally the same time, so that the completion of closing the door and the end of the performance can be made to coincide with each other, so that the battery is consumed and the link is exhausted. Even if the time required for opening and closing the door changes with time due to a load change due to a change in mechanical resistance of the mechanism or the like, it is possible to always match the end of the performance with the completion of closing the door.

As described above, in this embodiment, when the door or the decorative body, which is the movable portion of the decorative body timepiece, is operated by the motor for driving the movable portion, the operating time of the motor is measured and stored as the measured value T2. Since the operation of the motor is started before the time of the measured value T2 from the end time of the music, and the operation time at this time is stored as a new measured value T2, the decorative body clock that drives the door and the decorative body is used. The operation time of the motor for driving the movable portion is stored as a measured value T2, the operation of the motor is started a time corresponding to the measured value T2 from the end time of the music, and the operating time at this time is stored as a new measured value T2. Even if the operating time of the motor for stopping the door or decorative body as a movable part at a predetermined position changes with time, the stop of the movable part should always coincide with the end of the music. Can be.

Since the motor operation time at this time is stored as a new measured value T2, even when the motor operation time changes gradually, the operation of the movable unit is always performed while the stop of the motor and the end of the music are matched. Can be controlled. Also, in the above embodiment, a stable oscillator such as a crystal oscillator or a ceramic oscillator is used.However, when an oscillator such as a CR oscillator whose frequency changes due to voltage fluctuation is used, the playing time of each song is measured every time. By storing the measured time as the set value T1, the end of the music and the stop of the door can always be matched.

As described above, when measuring the performance time of a song together with the drive time of the door, which is a movable portion, not only the preset performance time of each song as the set value T1 of each song but also the time signal In some cases, the performance time is measured by operating only the melody IC 21 in advance using the time when no monitor signal is input. In this preliminary measurement, as shown in FIG. 4, when the microcomputer 10 is reset by replacing the battery or the like, the measurement flag of the set value T1 is turned off in the initial setting, and operation inputs such as an hour signal and a monitor signal are turned off. When there is no song, the measurement flag determines whether or not the measurement of the playing time of each song has been completed.If there is a song for which the playing time has not been measured, whether or not the song length is being measured is determined by the measurement execution flag. When it is determined that the execution flag is not turned on, the execution flag is turned on, and a start signal is output to the melody IC 21 to start measuring the playing time.

In this preliminary measurement, no operation signal is output to the amplifier 25, the speaker 27 is not sounded, and no control signal is output to the mechanism 29, and only the melody IC 21 is used. Is operated. When the execution flag indicates that the music length is being measured, the operation of the melody IC 21 is confirmed by the busy signal from the melody IC 21. When the input of the busy signal stops, the measurement ends and the measurement time is set as the set value T1. In addition to the storage, the execution flag is turned off, and it is determined whether or not the measurement of all songs has been completed.

When the measurement of the performance time of all the music pieces is completed in this way, the performance time is measured when the performance is performed based on the input of the hour signal, and the set value T1 is updated. If an operation signal such as an hour signal is input during the preliminary measurement, the measurement is interrupted and the operation of the stage is controlled. In this operation control, a door selection signal and a start signal are output to the melody IC 21 based on the preset value for the opening / closing of the door and the music performance for the first time, and then a control signal for closing the door with a time difference is output. Yes, when the music length measurement is completed, based on the set value T1 by measurement, and for the unmeasured music, based on the set value T1 by the preset value, after outputting the start signal, appropriately output a control signal based on the detection signal. Outputting the control signal to the mechanism 29 and outputting an appropriate control signal based on the detection signal are the same as in the above-described embodiment.

As described above, when the stage is formed, the performance time of the music, which is the operation time of the main mechanism, is measured and set to T1, and the operation time of the motor for driving the movable portion is also measured. The operating time of the door that has been set as the measured value T2, the time difference between the set value T1 and the measured value T2 is calculated,
After the start of the performance when the stage is formed, a control signal for starting the operation of the movable section driving motor is output after a lapse of a time difference between the set value T1 and the measured value T2, and the performance time and the operation time at this time are measured. The decorative body clock that updates the set value T1 and the measured value T2 to adjust the stop of the movable part always to the end of the music, even when the music playing time or the motor operating time changes over time. Is what you can do.

That is, in this embodiment as well, the operation time of the melody IC 21 as the main mechanism is measured and stored, and the operation time of the closing operation of the door as the slave mechanism is also measured and stored. Since the closing of the door is started with a delay between the two times, the end of the music and the completion of the closing of the door can be matched. The above embodiment is an embodiment in which the decorative body appears by opening the door. However, as shown in FIG. 5, an annular movable portion 25 provided with a pattern or a decorative body is provided around the dial 31 or the like. In the case where the movable portion 25 is returned to the original position and stopped still while being rotated every hour, half of the playing time is required.
In some cases, the motor is rotated forward only and the motor is rotated reversely for the same amount of time.

Also in this case, the mechanism mechanism 29 is a simple mechanism for rotating the movable part 25, and outputs a forward control signal and a reverse control signal of the driving motor from the microcomputer 10 as control signals. At the same time, the melody IC 21 is actuated by a start signal or the like, the playing time is measured and set to the set value T1, and the motor is rotated forward for a half of the set value T1 to rotate the movable portion 25 in one direction. Subsequently, the motor is rotated reversely for half the set value T1 to rotate the movable portion 25 in the reverse direction, and the movable portion 25 is returned to the original position based on the detection signal from the position detector, and is moved. Part 25
Is stopped and the performance of the music ends.

When rotating the motor to one side only for a half of the set value T1, this time is further divided into halves. First, the motor is rotated forward for a quarter of the set value T1. The motor is reversely rotated for a half of the set value T1, and the motor is continuously rotated forward for a quarter of the time again. The forward rotation time and the reverse rotation time are each set to a half of the set value T1. The rest position may be returned to the original position by setting it equal to 1.

The movable portion 25 is not limited to the case where the movable portion 25 is formed in an annular shape around the dial 31, but also the movable portion 25 that swings below the dial 31.
The same applies to the case where the movable section 25 is driven by forward rotation and reverse rotation of the motor. Therefore, when the movable part is operated, the performance time of the music is measured and set to a set value T1, and the performance time is measured again while driving the movable part driving motor at the start of the performance, and the previously measured set value T1 is set. The motor is rotated to one side for half the playing time,
In the case of a decorative body clock in which the set value T1 is updated by rotating the motor in the opposite direction to the above-described direction for the same time, the operation time of the motor for stopping the movable portion at the predetermined position changes over time. Even if it does, the performance time is measured, and the motor is moved in one direction by one half of the performance time.
Since the motor is rotated in the reverse direction for the same time, the movable part can be returned to a predetermined position and stopped, and the movable part can be stopped at the end of the performance. Can be constantly stopped at the end of the performance.

Further, in the above embodiment, the movable portion is rotated or swung, but the pattern or the shape can be stopped by rotating the movable portion by one turn or by rotating it by a fraction of a turn. When the movable part is rotated, the annular movable part 25 is rotated by a predetermined angle in accordance with the start of the operation of the melody IC 21, the time of this first rotation is measured, and a predetermined number of times are intermittently performed at a predetermined angle. The total time required for the movable part to operate is calculated by multiplying the time required for the first rotation of the movable part by an integer, and the difference from the set value T1, which is the operation time of the melody IC 21, is calculated as the number of stops. The stop time in the intermittent operation may be adjusted by dividing to make the end of the final operation coincide with the end of the music.

In this case, it is possible to intermittently rotate the motor in only one direction, or to combine forward and reverse rotations as appropriate. Further, the number of intermittent operations is set to an even number, and half of the total operation time is performed. Rotates the motor in the forward direction,
In one-half, the motor is reversed so that the final stop position of the decorative body is returned to the original position, and the end of the operation may coincide with the end of the music.

In the above embodiment, the operation of the melody IC 21 is mainly performed, and the operation of the door and the decorative body are used. However, the movable portion such as the door and the decorative body is used as the main mechanism to play music. A control circuit for controlling the operation when the melody IC 21 is used as a slave mechanism, or when a plurality of movable parts are used as a main mechanism and a slave mechanism,
Needless to say, a decorative clock having a control circuit for controlling music and music as master and slave can also be provided.
