載の自動視力計。[Scope of Claim for Utility Model Registration] (1) In an automatic visual acuity meter that selectively presents one optotype from among a plurality of optotypes to a subject, the presentation time of the selected optotype is selective. 1. An automatic visual acuity meter characterized by having an optotype presentation time control means for controlling. (2) The automatic visual acuity meter according to claim 1, wherein the optotype is selectively displayed by a liquid crystal display means. (3) The optotype presentation time control means includes an optotype presentation time setting device for setting a desired optotype presentation time, a clocking means for timing the presentation time of the optotype, and a setting device configured by the setting device. The present invention is characterized in that it is comprised of a comparing means for comparing the set presentation time set and the time measured by the time measuring means, and an optotype presentation control means for stopping the presentation of the optotype after the set presentation time elapses. An automatic visual acuity meter as set forth in paragraph (1) or (2) of the claims for patent registration.
