Abstract

The cassette moves parallel to the optical axis, with the image frames changed by a frame selector employing a shutter. A reversible electric motor is used for transport of the cassette, with the motor, a position indicator, for allowing the frame selector to be blocked, and a separation magnet for driving the shutter, connected together, as well as to a comparator circuit. The latter is connected via a memory to a keyboard for input of the characteristics number denoting the image frame to be selected, with a stepping counter placed in circuit with the control motor.
