POWER SAVING APPARATUS FOR CLASSROOM LINKED TO DOOR-FASTENER

摘要

PURPOSE: A power saving apparatus for a classroom linked to a door locker is provided to make it unnecessary to pay other special attention to power saving because the power is automatically supplied or cut off when the classroom door opens or closes. CONSTITUTION: A switch(SW) switches the power by turning on or off an electric line induced into a classroom. A controller(100) controls turn on-off of the switch. A relay(L) transmits a locking signal of a door lock in the classroom to the controller. A rod(10), whose one end can be inserted into or protruded out of a door, transmits locking signals by making the end contact and press the controller. An elastic body elastically supports the rod for inserting the rod into the door. A pushing unit protrudes the rod out of the door by pushing the other end of the rod when the door lock is locked.
