ABSTRACT:
A device for detachably mounting a manuscript on a rotary cylindrical drum for cylinder scanning type facsimiles. The device comprises a cam operating lever rotatable together with a drum cover, a segmental cam provided at its peripheral edge with stepped cam surface portions, and an arm for operating the clamping bar and having one end rotatably supported by a pin threadedly engaged with a shaft which is perpendicular to the pin and rotatable about its axis, the free end of the arm being resiliently urged against the stepped cam surface portions of the segmental cam and having a block piece for selectively operating the clamping bar. The selective operation of the drum cover only permits to raise the clamping bar from the rotary cylindrical drum so as to remove the manuscript and stop the rotary cylindrical drum and lower the clamping bar toward the rotary cylindrical drum so as to clamp the manuscript to the rotary cylindrical drum and rotate the rotary cylindrical drum.
