SECTION III
TYPE 123 CARD READER
The Type 123 Card Reader processes cards at the rate of
400 cards per minute on a demand-feed basis. The input medium
to the 123 is 80-column cards (standard) or 51-column cards
(optional). Starting with column 1, information is read optically
by means of 12 photocells; all columns are read serially until
column 80 (or 51) has been read. The information contained in
each column is decoded (i. e., translated into a six- bit central
processor character) by the integrated card control and is trans-
ferred by this control to the main memory. Data transfer is
terminated when the last column is read or when a record mark
is sensed in memory, whichever occurs first.
As shown in Figure 3-1, the basic components of the Type 123 Card Reader are an input
hopper, a wait station, a reading station, and an output stacker. The input hopper has a capacity
of 3,000 cards; the output stacker has a capacity of 2,500 cards. Cards may be loaded into the
input hopper or removed from the output stacker while cards are being read. Selected cards or
error cards may be offset-stacked in the output stacker •
