A mechanical preselection counter having: a counter, which has figure rollers and a zero-setting device for the figure rollers; a preselection unit having that number of preselection rollers and transmission of feed gears corresponding to the number of figure rollers, with the transmission gears being drivingly or operatively connected with the figure rollers; and with setting or adjustment elements associated with each preselection roller for setting or adjusting them, the adjustment elements being held in the rest position by spring force, being connected via a coupling device with the zero-setting device of the counter, and being operable with actuating elements. The preselection unit is provided with keying devices, each of which has at least two axially protruding noses which project through openings in the associated transmission gear, are respectively associated with a recess on the preselection rollers, and are loaded or biased by a releasing rack toward the preselection rollers. The two noses of the keying device, as well as the two recesses, are respectively spaced from each other in such a way that the noses, during a complete rotation of the transmission gear, only fall or drop in one position into the associated recesses of the preselection roller.
