ABSTRACT:
A film holder receives film chips for developing and enters through an input opening where a transport mechanism carries it into a developer tray having a thermistor for providing a signal representative of the developer temperature. This signal is used to control the development time to be inversely proportional to temperature. At the end of the development cycle the transport mechanism lifts the film holder from the developer tank, carries it to the fixing tank and deposits it in the fixing tank. At the end of the next development cycle, the transport mechanism lifts the film holder from the fixing tank, transports it to the wash tank and deposits it in the wash tank. At the end of the next development cycle, the transport mechanism lifts the film holder from the wash tank and deposits it in the drying chamber where forced hot air dries the developed fixed washed film chips. They may be removed through an exit door.
