For controlling a position indicator, e.g. a cursor, on a visual display, e.g. the monitor screen associated with a personal computer or a laptop computer screen, a position indicator controlling device (1) comprises an indicator position controller (6) in the form of a continuous membrane of elastomeric material (8) stretched, in wrinkle-free manner, around a solid form-keeping core (7) held captive in a housing (2) so that by applying finger pressure in a generally horizontal direction to an uppermost exposed, part-spheroidal, portion of the membrane, the membrane can slide on the core to produce a corresponding output signal from one or more motion detectors (11, 12). The indicator position controller gives the appearance to a user of a spherical ball device (such as is commonly used in a laptop computer), but the special shape of the form-keeping core is such as to reduce the overall height requirement and leads to a heightwise compact construction for the position indicator controlling device (1'). According to two modifications (FIGS. 5 and 6), the indicator position controller (6) is realized by a normally spheroidal thick-walled elastomeric ball (8'), or by a solid elastomeric ball (8'') held in a deformed state by the housing (2). The position indicator controlling device (1) can be designed for use as a ball-type device for a laptop computer or as a mouse for a personal computer.

The film roll carriage is operatively connected to negator spring members by a film roll carriage lift cable, and a holding pawl mechanism is adapted to be movable between ENGAGED and DISENGAGED positions with respect to the film roll carriage lift cable. When the holding pawl mechanism is moved to its DISENGAGED position, the negator spring members cause the film roll carriage to be vertically elevated, whereas when the holding pawl mechanism is disposed at its ENGAGED position, movement of the film roll carriage lift cable, and the film roll carriage, is effectively prevented. The film roll carriage can also be controllably moved in both upward and downward directions so as to achieve bottom-to-top, as well as top-to-bottom, wrapping modes of operation upon palletized loads.
