US 6,204,871 B1 · Recording drum arrangement

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 the available length of the clamping drum circumference which permits a very flexible and economical operation of the recording apparatus (FIG. 1).

Dependent claims

Apparatus for recording image information onto a planar recording medium, comprising:

a rotatably driven clamping drum having a mantle;
means for listening the recording medium on the mantle;
a recording unit stationary relative to the direction of rotation of the clamping drum for recording image information on the fastened recording medium, said image information being fed thereto in the form of electrical signals;
mounting means provided in an interior of the clamping drum for supporting a supply of recording medium wound up into a roll, the clamping drum having a slit in said mantle for permitting passage of the recording medium from the interior of the clamping drum onto the mantle;
and
a drive arrangement stationary relative to the direction of rotation of the clamping drum and engageable with the fastened recording medium in a defined rotational position of the clamping drum for advancing the recording medium on the mantle in the direction of rotation of the clamping drum;
said drive arrangement being movable to the mantle by a mechanism such that the drive arrangement comes into engagement with the recording medium and being moveable from the mantle by the mechanism such that the drive mechanism is lifted off the recording medium.
