Abstract
A microfilm duplicator for duplicating images received from a microfiche onto a duplicating medium. Images from the master microfiche are transferred to the duplicating medium at an exposure station. A duplicating medium support frame is operator moveable to cause the duplicating medium to be transported to a developing station wherein the duplicating medium is developed. The duplicating medium is then transported to a clearing station wherein unimaged areas are cleared from the duplicating medium and the duplicate is discharged at a discharge station. While one duplicate is being developed, a second duplicate can be exposed at the exposure station thus increasing throughput of the device.
