Abstract

A CRT data display comprises a display head of significant weight which may be moved vertically with the aid of constant force springs and which may be tilted to adjust the position of the CRT for operator comfort. The display may be rotated about a vertical axis to permit multiple viewing positions.

Claims

1. A data entry display station comprising:

a base,

a display head,

at least one vertical column defining limits of travel of said display head,

a constant force spring means supported by said column and attached to said display head to support at least a portion of the weight of said head,

means for retaining said head in a plurality of selected positions intermediate said limits of travel relative to said column.

2. The station of claim 1 wherein said means for retaining said head further comprises a latching means for preventing vertical movement of said head with respect to said column and means for permitting and preventing tilting of said head relative to said column.

3. The station of claim 1 wherein said station comprises two columns.

4. The station of claim 3 wherein said columns contain a plurality of constant force springs.

5. The station of claim 3 wherein each of said columns contain therein a plurality of said constant force springs.

6. The station of claim 1 wherein said base is further mounted on a support means.

7. The station of claim 6 wherein said support means further comprises means for allowing rotational movement of said base relative to said support means.

8. A data entry display station for electronic data processing comprising:

a base,

a pair of spaced-apart vertical columns mounted on said base,

a relatively massive positionable display head riding on said columns and vertically adjustable within limits therein,

constant-force (negator) spring means mounted in said columns for counterbalancing the weight of said display head, and

locking means for positively holding the display head at selectable vertical positions on the columns intermediate said limits.

9. The display station of claim 8 wherein said base further comprises means for rotationally supporting said station to permit rotation of said station about a vertical axis.

10. The display station of claim 8 comprising means for adjustably positioning said display head about a horizontal axis therethrough.
