Abstract

A data card housing (32) is provided which has a reading region (34) and a loading region (33). A data card is to be located at a reading position, and the reading region (34) has grooves (36) for guiding the card to the reading position. The loading region (33) has a supporting surface (31), and is arranged such that force can be applied to a major face of the card, to slide the card along the supporting surface (31) and into the guide grooves (36). Further, the reading region (34) is arranged such that force can be applied to the major face of the card to further slide the card to the reading position.

Claims

1. A data card housing for receiving a data card, comprising:

a recess including;

a reading region in which the card is located at a reading position, the reading region including a channel portion of the recess for guiding the card to the reading position and a loading region having a supporting surface, for guiding the card to the channel portion of the recess;

the recess being substantially open to permit access to a major face of the card in the reading region and in the loading region, so that force can be applied to the major face of the card, to slide the card along the supporting surface into the channel portion and so that force can be applied to the major face of the card in the reading region to further slide the card into the reading position.

2. A housing as in claim 1 wherein the supporting surface of the loading region slopes toward a bottom surface of the recess at the channel portion.

3. A housing as in claim 2 wherein the supporting surface of the loading region comprises a ramp.

4. A housing as in claim 2 wherein the open recess permits a force to be applied to the major face of the card to slide the card in an opposing direction for removal of the card from the housing.

5. A housing as in claim 2 comprising means associated with the recess for retaining the card in the reading position.

6. A housing as in claim 5 wherein the retaining means comprises at least one protrusion in the supporting surface of the loading region.

7. An assembly comprising a data card and a data card housing for receiving the data card, wherein:

the housing includes a recess comprising;

a reading region in which the card is located at a reading position, the reading region including a channel portion of the recess for guiding the card to the reading position and a loading region having a supporting surface for guiding the card to the channel portion of the recess;

the recess being substantially open to permit access to a major face of the card in the reading region and in the loading region, so that force can be applied to the major face of the card, to slide the card along the supporting surface into the channel portion and so that force can be applied to the major face of the card in the reading region to further slide the card into the reading position.

8. An assembly as in claim 7 wherein the supporting surface of the loading region slopes toward a bottom surface of the recess at the channel portion.

9. An assembly as in claim 8 wherein the supporting surface of the loading region comprises a ramp.

10. An assembly as in claim 8 wherein the open recess permits a force to be applied to the major face of the card to slide the card in an opposing direction for removal of the card from the housing.

11. An assembly as in claim 7 wherein the data card has data card contacts and wherein the housing at the reading position includes connector contacts for contacting the data card contacts to couple the data card contacts to circuitry.

12. An assembly as in claim 11 wherein the connector contacts are positioned to contact respective data card contacts when the data card is located in the reading position in a first orientation and the connector contacts are positioned so that only one data card contact is contacted by any one of the connector contacts coupled to circuitry when the data card is located at the reading position in a second orientation, 180 degrees rotated from the first orientation.

13. An assembly as in claim 11 wherein the connector contacts are positioned to contact more than two respective data card contacts when the data card is located at the reading position in a first orientation, and wherein only two data card contacts are contacted by the connector contacts when the data card is located in the reading position in a second orientation, 180 degrees rotated from the first orientation.

14. A radiotelephone including a data card housing for receiving a data card, including:

a recess comprising, a reading region in which the card is located at a reading position, the reading region including a channel portion of the recess for guiding the card to the reading position and a loading region having a supporting surface for guiding the card to the channel portion of the recess;

the recess being substantially open to permit access to a major face of the card in the reading region and in the loading region, so that force can be applied to the major face of the card, to slide the card along the supporting surface into the channel portion and so that force can be applied to the major face of the card in the reading region to further slide the card into the reading position.

15. A radio telephone as in claim 14 wherein the supporting surface of the loading region slopes toward a bottom surface of the recess at the channel portion.

16. A radio telephone as in claim 15 wherein the supporting surface of the loading region comprises a ramp.

17. A radio telephone as in claim 15 wherein the open recess permits a force to be applied to the major face of the card to slide the card in an opposing direction for removal of the card from the housing.

18. A radiotelephone as in claim 14 further comprising a detachable battery, which when attached to the radiotelephone covers the data card housing.
