Input I would have thought.

If you are refering to the big readers of the 80-column punched card then they are Input devices. But many of these devices were made so that they could also be used for output - ie for punching cards - these are both Input and Output devices.
A card reader is an INPUT (not imput) device.

Whenever you are trying to categorize a device as Input or Output, think of how it looks from the computer.

If the computer is transmitting data to it, it is an Output device.

If the computer is receiving data from it, it is an Input device.
