ABSTRACT:
A tennis scoring device is disclosed comprising an elongated body member having a longitudinal axis, with a visible tennis scoring indicia secured on the top surface of the body member and extending along the longitudinal axis thereof. The indicia strip is divided into a plurality of duplicate scoring segments representing the scores of the player and the opponent. A pair of slide members are resiliently slidably mounted on the edges of the body member and extend over the indicia strip. An aperture in each of the slide members provides visible access to a given indicia segment. The width of the body member is greater than the normal width of the slide members so that the slide members are slightly expanded upon being mounted on the body member to resiliently hold the slide members in position on the body member.
