Separable paper feed device and its separable paper feed performance maintenance manner

摘要

PURPOSE:To prevent deterioration of separating performance by turning a separating belt for a fixed time before starting a separating paper feed when the time of not turning the separating belt reaches the fixed time, in the case of a separating paper feeder by a roller and a belt for a copying machine or the like. CONSTITUTION:Time of not turning a separating belt 7 is measured by a timer 61. On the other hand, signals of a set sensor 6, resist sensor 11, etc., are input to a control means 60. When the set sensor 6 is turned on, only the separating belt 7 is driven for a fixed time before starting a paper feed when the non- turning time of the separating belt 7 reaches the fixed time. Thereafter, the belt is brought into press contact with a separating roller 8 to perform a separating feed.
