A binder has a device (10) for opening and closing a binder for storing sheets with an elongate mechanism (20) extending on the inside of the binder in the area of the spine (130) of the binder and along the spine. The mechanism comprises two spaced-apart strips (20a, 20b) which are movably connected to each other by at least one common hinge (30), said strips being connected to the inside of the binder. The mechanism further comprises cooperating forks (60, 70, 80, 90) fixed to the strips. |
