Unlocking large floor cabinets

"Unlocking due to lost key"

It was a library somewhere in Tokyo.This is my first place.The entrance was complicated and I had a hard time finding a common gate.

The place I was guided to was a fairly small office.There was a large cabinet, but it's ITOKI.

(Is this the type that needs to make a key?)

Looking at the carved seal, it is the N model number. (Maybe you can go by picking)

I was able to unlock it by picking. (It was a relief)
