Patent ID: 7537213

Claim:
An individual sheet member output control method used in a sheet member dispenser comprising a housing, which accommodates a stack of sheet members and has a sheet member outlet and a sheet member path for guiding said sheet members to said sheet member outlet, a transferring roller set adapted to transfer sheet members forwards to said sheet member path, a dispensing roller set disposed at a top side of said sheet member path and adapted to dispense sheet members from said transferring roller set to said sheet member outlet, and sensor means provided between said dispensing roller set and said sheet member outlet, the individual sheet member output control method comprising the steps of: (A) said sensor means judging whether or not overlapped sheet members have been dispensed; (B) when said sensor means judges that overlapped sheet members have been dispensed, reversing said transferring roller set to move overlapped sheet members backwards wherein an overlapped area is above a predetermined value and then rotating said dispensing roller set forwards to re-dispense the overlapped sheet members; (C) when said sensor means judges that overlapped sheet members are again dispensed after a secondary dispensing by said dispensing roller set, reversing said transferring roller set to move the overlapped sheet members backwards again, wherein said overlapped area is above said predetermined value and then rotating said dispensing roller set forwards to re-dispense the overlapped sheet members again; (D) reversing said transferring roller set to move the overlapped sheet members backwards and shut down said sheet member dispenser after step (C) has been repeated a predetermined number of times; (E) if said overlapped area of overlapped sheet members is below said predetermined value, rotating said transferring roller set forwards to deliver the overlapped sheet members toward said sheet member outlet and then reversing said transferring roller set to move the second sheet member backwards after the first sheet member has been moved out of said sheet member outlet.
