Abstract

PURPOSE:To enable the alarm announcement time with high accuracy, by closing the contact unit only when the both of the hour cam wheel and one minute cam wheel can close the contact unit, so that the announcement operation of electric announciator can be made. CONSTITUTION:In synchronizing with the revolution of clock wheel train, the switching operation of the contact 10 is controlled at specified announcement time and the numbering mechanism is provided to the time announcement machainsm to obtain the time announcement in response to this announcement time. The number of time knocks is set corresponding to the announcement time by controlling the number of revolutions of motor. The locking lever 28 is borne flexible on the shaft 30 fixed to the clock bearing plate, and the projection 32 formed at one end is extended so that it can be suitable coupled with the rack gear 34a of the comb gear 34. This locking lever 28 is energized always toward the arrow B direction with the pring 35, and the depression section 36 of circular arc shape is provided so that it can be coupled with the moving contact plate 10a.
