    • A receiver has an oscillator for generating an oscillating signal at an oscillating frequency in accordance with an oscillation control signal, and receives a radio signal at a tuning frequency corresponding to the oscillating signal to demodulate the received radio signal. The receiver further includes a first frequency control loop system for generating a first control signal indicative of the difference in phase between a comparison signal generated by dividing the oscillating signal on the basis of the information on a channel selection frequency and a reference signal, and a second frequency control loop system for generating a second control signal indicative of a frequency difference between the oscillating frequency of the oscillating signal and the channel selection frequency. Either the first control signal or the second control signal is selectively supplied to the oscillator as an oscillation control signal.

    • A photographic printing apparatus includes a lens unit and a lens mount which are joined to each other in a separable manner. The lens mount includes therein a drive motor and a drive force transmitting mechanism to adjust the focal distance and aperture of the lens unit. A plurality of lens units having different focal distances are provided, from which a lens unit suitable for a printing magnification is automatically selected for printing. Each lens unit is provided with external connection members which are connected to an aperture adjusting mechanism and the focal distance adjusting mechanism of the lens unit. The lens mount to which the lens unit is attached is provided with members which are engaged with the external connection members of the lens unit to displace them. The displacement of these members is effected by motors provided on the lens mount. With this structure, the cost of lens units can be reduced, and the efficiency of the printing operation can be increased.

    • An apparatus for selectively supplies one of a plurality of photosensitive materials having different widths to an exposure unit. The width of the potosensitive material and the exposure unit.The width of the photosensitive material and a width of the image frame are detected. By comparing the detected widths with each other, a control circuit will select the magazine accommodating the photosensitive material having a width corresponding to that of the image frame. If the selected magazine is already supplying the photosensitive material, it continues to feed it. If not, the control circuit will command to cut off the exposed portion of the photosensitive material, rewind its nonexposed portion by the transfer means, and deliver only the printed photosensitive material remained in the exposure unit. Then, the control circuit selects the photosensitive material whose width corresponds to that of the image frame. Thus, the photosensitive material is changed over automatically according to the width of the image frame of the negative film.
