MECHANISM
Positioning the input hopper in a Type 123 reader equipped to handle the optional 51-column
cards is an operator function.
A casework interlock prevents changing the position of the hopper
while the device is running.
The photograph below shows the input hopper in the 51-column posi-
tion.
To change the position of the hopper, the longitudinal piece (which the trailing edges of the
cards rest against while in the input hopper) may be lifted upward and swung in an arc on a me-
chanical linkage to the opposite (80-column) position.
When reading 51-column cards, it is
necessary to use a 51-column card weight in the input hopper.
