Memory card reader unit and corresponding transactional data processing terminal
View Patent ↗A memory card reader unit, which has a generally rectangular parallelepiped shape. The unit includes a memory card insertion face having an insertion recess and an insertion slot for a memory card, which has a lower lip and an upper lip. The lower lip extends longitudinally and parallel to an insertion plane of a memory card in the reader unit, forming an extended insertion lip extending beyond an insertion plane.
1. A memory card reader unit comprising:
a generally rectangular parallelepiped shape; and
a memory card insertion face, said insertion face comprising:
an insertion recess; and
a memory card insertion slot, said insertion slot comprising a lower lip and an upper lip, wherein said lower lip extends longitudinally and parallel to an insertion plane of a memory card in said insertion slot and forms an extended insertion lip extending beyond the upper lip and an insertion plane of the memory card insertion face and wherein said extended insertion lip comprises a surface facing and adjacent to the insertion slot and at least two tabs of predetermined height extending from the surface in a direction generally perpendicular to the surface and the insertion plane of a memory card in said insertion slot, said at last two tabs being disposed under the insertion plane of a memory card in said insertion slot, between lateral side edges of the insertion slot.
2. The memory card reader unit according to claim 1 , wherein the surface of said extended insertion lip is substantially flat and parallel to the insertion plane of a memory card in said insertion slot.
3. The memory card reader unit according to claim 1 , wherein said at least two tabs form a predetermined angle with the surface of the extended insertion lip, the surface being substantially flat and parallel to the insertion plane of a memory card in said insertion slot.
4. The memory card reader unit according to claim 1 , wherein said at least two tabs are spaced apart by a distance substantially equal to the width of a magnetic strip of a memory card.
5. A transactional data processing terminal comprising:
a keyboard for entering personal identification data,
a screen for viewing transactional data,
a transactional data processing module; and
a memory card reader unit comprising:
a generally rectangular parallelepiped shape; and
a memory card insertion face, said insertion face comprising:
an insertion recess; and
a memory card insertion slot, said insertion slot comprising a lower lip and an upper lip, wherein said lower lip extends longitudinally and parallel to an insertion plane of a memory card in said insertion slot and forms an extended insertion lip extending beyond the upper lip and an insertion plane of the memory card insertion face, and wherein said extended insertion lip comprises a surface facing and adjacent to the insertion slot and at least two tabs of predetermined height extending from the surface in a direction generally perpendicular to the surface and the insertion plane of a memory card in the insertion slot, said at last two tabs being disposed under the insertion plane of a memory card in the insertion slot, between lateral side edges of the insertion slot.
