  • Patent number: 4281917
    Abstract: An information display device for a camera which comprises a power source, an information display circuit, a timer circuit, and switch means for operating the timer circuit to connect the information display circuit to the power source for a fixed time. The switch means includes a first switch which is turned on while being shifted from an OFF to ON position, a second switch connected in series with the first switch, and a third switch connected in parallel with the second switch and interlocking with the first switch. The third switch is so designed as to be turned on to operate the timer circuit while the first switch is shifted from the OFF to ON position and to be already turned OFF when the first switch is brought to the ON position. Preferably, the first and third switches are rotary switches with a common movable contact, and the second switch is a self-restoring switch, such as a push switch.
