TYPE 214-2 CARD READER/ PUNCH
The Type 214-2 Card Reader/ Punch reads standard 80-
column cards at the rate of 400 cards per minute and punches
80-column cards at a rate which varies from 100 to 400 cards
per minute, depending upon the last column punched. A special
operating mode (called the punch-feed read mode) makes it
possible to read a card, process the information read, and punch
additional information into the same card in a single pass. Type
214-2 card punch operations are identical to those of the Type
214-1 card punch (see Section IV).
For card reading on the Type 214-2, information is read optically by means of 12 photo-
cells, starting with column one. All columns are read serially until column 80 has been read.
The information contained in each column is decoded (i. e., translated into a six-bit character)
by the integrated card control and is transferred by this control to main memory. Data transfer
is terminated when the last column is read or when a record mark is sensed in memory, which-
ever occurs first.
As shown in Figure 5-1, the basic components of the Type 214-2 Card Reader/ Punch are
an input hopper, a wait station, a reading station, a punching station, and an output stacker.
The input hopper has a capacity of 1,200 cards; the output stacker has a capacity of 1,300 cards.
Cards may be loaded into the input hopper or removed from the output stacker during reading or
punching. Selected cards or error cards may be offset-stacked in the output stacker •
