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: A shutter arrangement is disclosed which at pre-selected intervals opens and closes to either permit light to illuminate a document plane or reflect light to the photoconductor of an electrostatic copying machine having the capability of half tone development, thus preventing the toning of unexposed areas of the photoconductor which bear no relation to the document being copied. The control arrangement opens the shutter during the normal scanning portion when a document is exposed to the illumination light and closes the shutter at a point corresponding approximately to the end of the document scan thus reflecting light to the photoconductor as if the photoconductor was receiving light from a white document, to discharge the unused portion of the photoconductor. This prevents excessive toning and the associated cleaning problems since this portion of the photoconductor will not have the toner transferred from it to a copy sheet.

Abstract: The invention concerns a method and apparatus for operating a multibin sheet collator, particularly a copier/collator installation. Additional to the number of sets to be collated, the number of sheets contained in each set is entered into the collator logic. If this number of sheets in a set exceeds the capacity of a single collator bin, adjacent bins are grouped together and treated as one virtual bin with increased capacity, thus extending the collator usage. Sheets exceeding the total capacity of the collator can be fed into additional receptacles.

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.
