Abstract
A photographic apparatus in which strip-shaped material is to be advanced by means of a travelling leader tape, has a carrier for the strip-shaped material, the carrier being formed with a channel. An arrangement is provided by means of which the leader tape can be sprung into the channel in response to a command signal so that a mechanical connection becomes established between the leader tape and the carrier and the latter is taken along by the travelling leader tape.
Claims14
In a photographic apparatus, particularly a developing apparatus, a combination comprising a travelling leader tape having transversely spaced edges;
- a carrier to which material to be advanced by said leader tape is to be attached, said carrier being formed with a channel;
- first means for holding said carrier in position proximal to said leader tape;
- and second means for causing said leader tape to become lodged in said channel in sprung condition, so that the leader tape engages and entrains said carrier, said second means comprising deforming means for deforming said leader tape transversely of its direction of travel so that said edges become spaced from one another by a distance smaller than the width of said channel, effecting entry of said leader tape into said channel, and thereupon terminating said deflection so that said leader tape becomes sprung in said channel and said carrier thus becomes connected to said leader tape for travel with the same, said deforming means including roller means mounted adjacent one major surface of said leader tape for free rotation about a fixed axis, and a presser element mounted adjacent the opposite major surface of said leader tape for movement towards said roller means so as to press said leader tape towards said axis of said roller means.
In a photographic apparatus, particularly a developing apparatus, a combination comprising a travelling leader tape;
- a carrier to which material to be advanced by said leader tape is to be attached, said carrier being formed with a channel;
- first means for holding said carrier in position proximal to said leader tape;
- second means for causing said leader tape to become lodged in said channel in sprung condition, so that the leader tape engages and entrains said carrier, and detecting means arranged adjacent said leader tape upstream of said position of said carrier, as considered in the direction of travel of the tape, for detecting the approach of a tape-end connector and, in response to such detecting, for generating a signal to prevent operation of said second means.
In a photographic apparatus, particularly a developing apparatus, a combination comprising a travelling leader tape having transversely spaced edges;
- a carrier to which material to be advanced by said leader tape is to be attached, said carrier being formed with a channel;
- first means for holding said carrier in position proximal to said leader tape;
- and second means for causing said leader tape to become lodged in said channel in sprung condition, so that the leader tape engages and entrains said carrier, said second means comprising deforming means including a deforming element mounted adjacent one major surface of said leader tape for deforming said leader tape transversely of its direction of travel so that said edges become spaced from one another by a distance smaller than the width of said channel, effecting entry of said leader tape into said channel, and thereupon terminating said deflection so that said leader tape becomes sprung in said channel and said carrier thus becomes connected to said leader tape for travel with the same, said deforming means further including a presser element mounted adjacent the opposite major surface of said leader tape for movement towards said deforming element so as to press said leader tape towards the same.
