Tape-shaped medium`s e.g. cinematographic film, position determining method, involves determining where image counter is incremented or decremented by constant conveying direction signal

摘要: The method involves determining whether a conveying direction (DIR) is constant during specific period or range. A (KDIR) signal indicates and direction. An image pulse created as counting in an counter when the for KDIR determines incremented decremented. independent claim also included device position of tape-shaped medium.
