Abstract

PURPOSE:To prevent the chattering of time informing device, by providing the contact device which electrically controls the operation of time informing device, hour cam controlling the contact device possible for closing, and contact release cam controlling the contact device in switching operation free. CONSTITUTION:The time informing device is provided with the contact device 10 to electrically control the operation of the electronic tone generator, and the contact device 10 is provided with the moving contact plates 11 and 12. The cam 19 in synchronizing revolution with the clock train wheels is provided to control the switching operation of the contact device 10, and the contact drive force of the hour cam 19 is delivered to the contact device 10 via the switch lever 14. Further, the contact release cam 30 is incorporatedly formed with the hour wheel as shown in figure to simplify the constitution, 12 pieces of cams 31 are formed at the external circumference and each cam is constituted so that it is turned by one pitch revolution in 1hr. Thus, the contact pressure can be kept constant to prevent the chattering.
