<P>PROBLEM TO BE SOLVED: To provide a bell ringing device which enables an user to enjoy a natural simmering sound of a wind-bell under an environment without natural wind. <P>SOLUTION: A bell ringing device includes: a pendulum 6 which is connected, using a flexible cord 17, to a joint 16 off the rotation center of the joint 16 integrated with the rotation axis 15 of a driving motor 7, and is powered by the driving motor 7 to swing and hit a bell body 1, so that the bell rings; a driving interval setting unit 23 which generates a driving signal for driving the driving motor at a constant time interval; a storage unit 24 which stores a driving pattern of the driving motor which is driven for every driving time specified by the driving interval setting unit 23; a driving control unit 25 which drives the driving motor for every driving time specified by the driving interval setting unit 23 based on the driving pattern stored in the storage unit 24, so that the pendulum 6 swings and hits the bell body and the bell rings. The bell ringing device drives the driving motor at the constant time interval and drives it based on the constant driving pattern for every driving time, so that the pendulum 6 swings and the bell rings. <P>COPYRIGHT: (C)2012,JPO&INPIT |
