Abstract

A timer function hold mode in which the timer continues the timing function is set in a mydriatic fluorescence mode by operating a timer switch for at least a fixed time, or by simultaneously operating a fluorescence filter switch and the timer switch. If the timer function hold mode is set in the mydriatic fluorescence mode, then the timing of the timer is continued even after the photography mode switches to another photography mode e.g. non-mydriatic or mydriatic color mode. When, on the other hand, the timer function hold mode is not set in the mydriatic fluorescence mode, the timer is caused to be stopped or reset when the mode is switched to the non-mydriatic or mydriatic color mode.

Dependent claims

An ophthalmic photographic apparatus having a plurality of photography modes and a timing means for measuring the elapsed time since its start by the command of a user, comprising:

a timer function holing means responsive to a prescribed timer function hold operation in a first photography mode to set a timer function hold mode;
wherein, when the timer function hold mode is set in the first photography mode, the timing means continues measuring the time even after the mode is switched therefrom to a second photography mode, and when the timer function hold mode is not set in the first photography mode, the timing means is caused to be stopped or reset when the mode is switched to the second photography mode.
