A visual presenter 1 comprising a camera head 17 supported on the distal end of an upright support column 13 extending from a base 3, the support column 13 being bent such that it has a vertical portion 13a and a horizontal portion 15, the horizontal portion 15 protruding away from or in front of the base 3 and the vertical portion 13a having a pivot 121 such that the column twists or rotates such that the horizontal portion 15 moves horizontally (figs 5, 6). The column may also pivot vertically (fig 10) and the camera head may be rotatable about the support (fig 6). The base 2 may be magnetically attached to a placement surface 101 using magnetic positioners (6, 7, 102, 104 fig. 11). A return spring (37, fig. 3) and stopper (42, fig 3) may control the vertical movement of the column 13 such that it can be positioned at any tilt angle i.e. they provide free stop motion. |
