Abstract

An image-recording drum apparatus includes a rotatably driven clamping drum (100), means (160) for the fastening of a recording medium (M) on the mantle (110) of the clamping drum and a recording unit (200) which is stationary relative to the direction of rotation of the clamping drum and records on the recording medium (M) fastened onto the mantle of the rotating clamping drum (100) image information fed thereto in the form of electrical signals. Mounting means (120) are provided in the interior of the clamping drum (100) for supporting a supply of recording medium (M) wound up into a roll (130). The clamping drum (100) has a slit (140) in its mantle (110) through which the recording medium (M) can be guided from the interior of the clamping drum (100) to its mantle (110) and fastened thereon. The feeding of the recording medium from the interior of the clamping drum is on the one hand constructively especially simple and advantageous and on the other hand permits the cutting of the recording medium only after the recording of the image information to the respectively required exact length without generating clippings. The picture format can thereby be arbitrarily varied within th…
