ABSTRACT:
A zoom camera has a push button switch that is constituted of a single disc virtually radially divided into sections, and switches disposed behind the sections one by one. The single disc is supported in a center such that the single disc tilts in a different direction when pushed at one of the sections, and returns to a horizontal state by a spring force. One of the switches is actuated to output a signal when a corresponding one of the sections is pushed. The push button switch doubles as a mode setting operation member and a zooming operation member. When the mode setting operation is designated by a manually operable switch, the signals from the switches are used for the mode setting. Otherwise, the signals from the switches are used for zooming.
