ABSTRACT:
A single lens reflex camera provided with a swing-up mirror which is held in the retracted position while pictures are successively taken. A delay circuit is connected between a shutter release signal generator and a leading shutter blind driving circuit for delaying the transmission of the shutter release signal to the leading shutter blind driving circuit when pictures are normally taken. The delay circuit has a switch which selectively makes the delay circuit functions to delay the signal transmission or nullifies the delay circuit to transmit the signal without delay. The switch is connected with the swing-up mirror to nullify the delay circuit when the swing-up mirror is held in the retracted position to conduct the successive photographing.
