Abstract
A lockable cassette (,) having a lid (,) is closed and locked when removed from a cassette casing but is released and unlocked when inserted into the casing by virtue of the actuation of an element (,) which functions to move a lock bolt (,) from a lid-latching starting position to a lid release position. The element includes an electric relay (,) and a two-arm lever (,). A core (,) of the relay is attached to one arm (,) of the two-arm lever and is actuable by a first pressure spring (,), wherein the other arm (,) of the lever forms abutment surfaces or stop surfaces for the lock bolt in its lid latching position when the relay is inactive. The arrangement further includes a second pressure spring (,) which is attached to a counterweight (,) which, when the relay is inactive, lightly abuts, but is not fastened to, the other arm (,) of the two-arm lever for actuation of the lever in a direction opposite to the direction in which the core moves to allow the lock bolt to occupy the release position. The first pressure spring, the second pressure spring and the counterweight are configured to balance the mass of the relay core.
