The Data Station is a device that acts like a card punch, but instead makes disk files.
It looks nothing like the 3720 family, so I'd guess it's the 5280 family. I'd say buckling spring, as the 5280s were in the 1980s, but those keycaps look like double-shot spherical keys, which is a dead giveaway that it's beam spring, if it is the 5280 family.
It's somewhere between a dumb terminal and a keyboard and monitor for a dumb terminal. A little smarter than just a keyboard and monitor, but not much.
