Title: Paper sheet conveying device
Inventor: KIKUCHI MASAYUKI
IPC: B65H7/12
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a detection error of double feed by storing the thickness measured value of a paper sheet in place of the thickness reference value of a paper sheet, stored in a thickness recording part and a file, to update the thickness reference value of the paper sheet in the case of not detecting double feed in a comparing part. SOLUTION: A measuring part 3 measures the thicknes of a paper sheet by the position displacement of a paper sheet feed roller and the detected light quantity of a photosensor and sends the measured value to a control part 4. The control part 4 receives the measured value and examines whether this paper sheet is the first one or not. In the case of indicating the first one, the measured value is stored as the thickness reference value of the paper sheet in a thickness storage part 1, and control is continued. In the negative case, the control part 4 sends the thickness measured value of the paper sheet and an instruction of comparison between the measured value and the reference value to a comparing part 2.  The comparing part 2 subtracts the measured value from the thickness reference value of the paper sheet read from the thickness storage part 1, examines double feed or not on the basis of whether the absolute value from the result of subtraction is larger than the predetermined value and sends the result to the control part 4.

Abstract: PROBLEM TO BE SOLVED: To reduce the load of the routing processing of layer-three packets in an ATM network and to realize high speed transfer. SOLUTION: When the gateway 11a of the entrance-side of an ATM network detects the flow of a packet received from existed LAN, private VC is allocated to the flow and a BIDN message 14a showing flow VC allocation information is transmitted to an adjacent switch 12a to a flow transfer destination. The switch 12a, which has received the BIND message 14a, executes routing by flow information in the BIND message and allocates private VC to the transfer destination against the flow. A BIND message 14b is transmitted to the adjacent switch 12b of the transfer destination. The operation is repeated to the exist-side gateway egress GW 11b and VP/VC is secured. VC of a reception-side and a transmission-side are cell-switched by an ATM switch. Thus, the packet of the flow is transferred at high speed in the cell as it is.
