Abstract: A dictating unit has an associated microphone with control buttons for establishing modes of operation and otherwise controlling the unit. The dictating unit is arranged for loading and unloading of a magnetic belt from the side. A transcribing unit has an associated headset and foot control and is arranged for loading and unloading of the magnetic belt from the front of the unit. However, each unit makes use of the same basic frame and common operating mechanisms. For maximum convenience, the common mechanisms are oriented in a preferred direction, differing by 90*, with reciprocable movement of transducer and index means in the dictating unit and transverse movement (at 90*) of the transducer and index means in the transcribing unit.

Abstract: 1,224,910. Dictation machines. INTERNATIONAL BUSINESS MACHINES CORP. 2 Oct., 1969 [14 Oct., 1968], No.- 48403/69. Heading G5R. The Specification describes and claims the manner in which a belt record is loaded into and ejected from a dictation machine generally described in Specification 1,224,909. A lever (10, Figs. 1,4, not shown), is moved to the right to position a belt gripper 50 to receive a belt 2 and in so doing retracts one of two rollers (63, 64) over which the belt is eventually positioned. The belt is inserted between jaws 53, 54 and pivots the upper jaw to free it from a rack 59 which would normally prevent the gripper being retracted. The lever (10) is returned to the left to retract the gripper until the jaw 53 engages a stop 62 to release the belt and to restore the roller (63) to its operational position. The belt has an aperture (2a) to provide for repeatable registration and the head is driven to record a helical track. The belt is ejected by moving lever (10) to the right until the gripper engages a stop 66, Fig. 7b, to cause the upper jaw to initially grip the belt and prevent its complete ejection after which spring 69 returns the gripper slightly to release the belt for manual withdrawal.
