The invention relates to a cassette particularly for bank notes. The object of the invention is to provide a cassette which will give an indication if it is tampered with. The cassette has a shutter which can be opened to remove the contents and mechanism to move the shutter from a first position to a second position when actuated by an external actuator means. When the external actuator is removed the mechanism automatically returns the shutter to the first position. Means are provided to prevent further movement of the shutter after it has returned to the first position. In the drawings (FIG. 5), shutter 12 is actuated by rods 30 acting against the tension of spring 26. The shutter is held against movement by latch 44 engaging bar 24. When key 57 is turned through 180 DEG , end 51 of bar 50 lifts latch 44 against spring pressure to allow shutter 12 to be opened by rods 30. Bar 50 is held in this position by engagement of rod 46 in slots 52, but is released as the shutter opens and spring 54 returns bar 50 to position shown in FIG. 5. When shutter is closed latch 44 holds it closed and the shutter cannot be opened again thus indicating that it has been used once, or tampered with. |
