DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a timepiece in which an electronic melody is emitted at a predetermined time, a bell is hit by a doll in synchronization with the melody, and a consonant sound from the bell is emitted in synchronization with the melody. About.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open Publication No. 2-69397 discloses a timepiece in which a bell is struck and a bell sound is emitted at a predetermined time. Japanese Patent Laid-Open Publication No. Sho 63-68699 discloses a direct hitting mechanism, in which a ball is attached to a leaf spring to which a permanent magnet is fixed, the leaf spring is attracted by energizing the coil, and the leaf spring is restored by interrupting the energization. By force
A mechanism for hitting a hit ball to a bell is disclosed.
In the timepiece according to these disclosures, a heavy and elegant tone of a bell that is actually struck flows on the timepiece that the electronic melody flows, and the timepiece effect can be enhanced.

[0003]

However, according to these disclosed methods, if the doll is to perform a bell-hitting operation, the operation of the doll is a pseudo-bell-hitting operation that does not actually hit the bell, and the operation of the doll is performed. This kind of timepiece that senses through the visual sense is not sufficiently effective.

The present invention has been made in view of such circumstances, and has as its object to synchronize a digital melody issued at a predetermined time with a doll to actually hit a bell, thereby making the doll uncomfortable. An object of the present invention is to provide a timepiece that can play no melody.

[0005]

To achieve the above object, the present invention provides a melody output means for outputting a melody,
A doll that raises and then swings down the hammer to ring a bell, and a driving unit that drives the doll, and at a predetermined time, a melody is emitted from the melody output unit, and at the same time, a synchronization is output from the melody output unit. A signal is used to drive the doll by the driving means, and in synchronization with the melody, the bell is hit by the hammer to generate a bell sound, which is necessary for raising and lowering the hammer. There is provided delay means for delaying the output of the melody from the melody output means by a required time by inserting a pause.

In the timepiece of the present invention, a plurality of the bells are provided corresponding to each scale, and the bell is provided by the synchronization signal.
One of the plurality of bells is selected, and a consonant of the bells of the selected scale is emitted in synchronization with the melody.

According to the timepiece of the present invention, when the melody is output at a predetermined time, the output of the melody from the melody output means is delayed by the delay means in accordance with the insertion of the pause. As a result, the melody is emitted from the melody output means, and at the same time, the doll is driven by the drive means by the synchronization signal output from the melody output means, and the bell is hit by the hammer and the bell sound is emitted in synchronization with the melody. Can be
