An apparatus having a first table and a second table carrying a negative and photosensitive film under a member having an elongated slit. A light source projects light through the slit to expose the film as it moves under the slit. Motion transmitting control structure is operable to move the second table at a speed which is equal to or less than the speed of the first table. The motion transmitting structure has an angularly adjustable arm connected to the first table. A movable member located in a guideway is connected by a cable to the second table and engageable with the arm whereby on movement of the first table the arm moves the movable member which in turn moves the second table. The speed of the second table relative to the speed of the first table depends on the angular position of the arm. The apparatus has an accessory for changing a linear image to an arcuate image. This accessory has a disc located in driving engagement with the first table whereby the disc is rotated on movement of the first table. The negative or film is attached to the disc so that it rotates with the disc and moves arcuately relative to the movement of the first table. A second accessory has a member for carrying a negative or film movably mounted on the first table. An arm secured to a support engages a part of the member so that on movement of the first table the member moves with the first table and relative to the first table. |
