comprises an upper spool member 68 containing a quantity of recording tape 69 as is evident in the drawing the free end portion of tape 69 passes behind guide post 88 across the curved face of announcement head 89 and is secured to take up reel 63 by a tape fastening peg 81 the actuator arm 82 of a double pole single throw rewind limit switch 83 is received between the upper and lower reel flange members of take up reel 63 mechanical operation of the announcement deck is described in detail in above mentioned u s pat no 3 833 186 summarizing briefly however the motion of a flywheel 40 in the answering device is transmitted by o ring drive belt 45 to a lower cylindrical member 66 of supply reel 62 member 66 is frictionally coupled to upper spool member 68 of the supply reel thus providing a constant motion in the reverse or rewind tape direction so long as fwd a solenoid 87 remains deactuated the condition in which it is shown in fig1 announcement tape 69 is rewound until taut whereupon slippage occurs between upper spool member 68 and lower cylindrical member 66 when fwd a solenoid 87 is energized by an appropriate signal pivotal arm 84 forces take up reel 63 into frictional engagement with a spindle 41 in flywheel 40 causing take up reel 63 to be driven in the forward tape direction the winding of tape on the hub of the take up reel forces actuator arm 82 away from the hub thereby throwing announcement rewind limit switch 83 to the opposite configuration the forces due to the.
