Abstract

PROBLEM TO BE SOLVED: To realize a time announcing clock for enabling a doll to strike a bell in synchronization with the melody of an electronic sound emitted at a specific time. SOLUTION: When a specific time has come, a melody generation circuit 10 generates an electronic sound melody and a motor 15 which is driven by a motor drive circuit 12 being controlled by a control circuit 11 by a synchronization signal outputted from the melody generation circuit 10 causes a doll 3 to swing upward and then downward a hammer to ring a bell 5. In this case, the delay means of the melody generation circuit 10 inserts a pause into the melody generation circuit 10 and delays the output of melody from the melody generation circuit 10 by the time required for the doll 3 to swing upward and downward the hammer, thus generating a bell sound obtained after the doll 3 strikes the bell 5 with the hammer completely in synchronization with the melody from a speaker 13.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a timepiece clock in which an electronic melody is emitted at a predetermined time, a bell is struck by a doll in synchronization with this melody, and a consonant sound from the bell is emitted in synchronization with the melody. Regarding

[0002]

2. Description of the Related Art As a timepiece clock in which a bell is struck and a bell sounds at a predetermined time, Japanese Utility Model Laid-Open No. 2-69397 discloses a plunger that is attracted and repelled by a solenoid. In Japanese Utility Model Laid-Open No. Sho 63-68699, a mechanism for directly hitting is mounted with a striking ball on 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 cutting off the energization. By force
A mechanism for hitting a bead on a bell is disclosed.
In the timepiece timepieces according to these disclosures, a heavy and elegant tone color of a bell that is actually struck flows to the timepiece timepiece in which an electronic melody flows, so that the timepiece effect can be enhanced.

[0003]

However, in these disclosed methods, when the doll tries to perform a beating action, the action of the doll becomes a pseudo beating action without actually hitting the bell, and the action of the doll occurs. The time effect is not sufficient for this type of time-of-day clock that senses through the eyes.

The present invention has been made in view of such circumstances, and an object thereof is to make a doll actually hit a bell in synchronism with an electronic melody emitted at a predetermined time, which causes a feeling of strangeness. It is to provide a time signal clock that can play a melody that does not exist.

[0005]

In order to achieve the above object, the present invention provides a melody output means for outputting a melody,
A doll that swings a hammer up and then swings down to ring a bell, and drive means for driving the doll, and at a predetermined time, the melody output means outputs a melody and at the same time, the melody output means outputs synchronization. A time signal timepiece in which the doll is driven by the drive means by a signal, and the bell is struck by the hammer to emit a bell sound in synchronization with the melody, which is necessary for swinging up and down the hammer. There is a delay unit for delaying the output of the melody from the melody output unit by inserting a rest symbol for the required time.

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

According to the time signal clock of the present invention, when the melody is output at the predetermined time, the delay means delays the output of the melody from the melody output means in response to the insertion of the rest mark. As a result, the melody is output from the melody output means, and at the same time, the synchronizing signal output from the melody output means drives the doll by the drive means, and in synchronization with the melody, a bell is struck by a hammer and a bell sound is emitted. To be
