In a hand stamp mount device especially suitable for a preinked stamp impression member that can give great numbers of imprints, the downstroke distance of a substantially rigid, non-rotatable assembly of a handle, a stem and a platen for carrying the impression member is adjustable precisely by turning with one's fingers an adjuster that correspondingly turns a stroke limiting stop member and causes it upon turning to be displaced proportionately lengthwise of the stem. Several ways of effecting the adjustments are disclosed, including some which eliminate all need for screw-threaded parts by making use of a molded ramp member presenting helical ramp surfaces. The platen and a case enclosing it are stiffened to resist stamping forces by an array of integral radiating ribs protruding upwardly from the platen and another array of such ribs protruding downward from the top of the case; and the ribs of the two sets intercalate to occupy vertical space in common when the platen is in normal upward position. A cover closing the case presents structures which limit downward movement of the platen, and structures connecting the cover with the case resist removal of the cover otherwise tha…
