Definitions

• the present invention relates to a display means with a removable cassette.
• the patent document US 6, 571 , 496 relates to a portable visual display device with removable cassette.
• the visual display device has a holding member, and the cassette can be removably inserted into and removed from the holding member. This is done from the end of the holding member. The screws holding the outer end cap on one side are removed. Thereafter, the outer end cap is removed. Finally, the cassette slides out.
