Abstract

PURPOSE:To obtain a contact device having a time announcing mechanism causing no chattering phenomena by electrically controlling the operation of a time announcement device through using a magnetosensitive switch. CONSTITUTION:The cam controlling forces of the 2nd hour cam wheel 33 and a 1min cam wheel 22 are transmitted to a control lever 14 having a magnet 15, and the magnet 15 installed to the lever 14 controls the opening and closing operations of a lead switch 13. In order to control the opening operation of the switch 13, the 1st hour cam wheel 30 rotating synchronously with train wheel is provided. The cam control force of the wheel 30 is transmitted to a rocking lever 1 and the projection 4 of the lever 1 engages with the lever 14 and controls the opening operation of the switch 13. When the switch 13 is closed, an hour striking motor rotates, and an hour striking action takes place. At this time, a feeding cam 10 operating cooperatively with the hour striking motor revolves, and feeds and drives the rack teeth 7 of a rack 6 at every hour striking action per time, thereby performing hour striking of prescribed times.
