The ornamental design for a data-collection apparatus, as shown and described.
FIG. 1 is a left front perspective view of a data-collection apparatus
showing my new design; and
FIG. 2 is a right rear perspective view of said apparatus.
The recess in the bottom panel, shown at the lower left corner of FIG. 2,
is rectangular in shape, and extends toward the front panel a distance of
four times the height of the adjoining recess in the rear panel.
