Filed: 1986-11-29
Abstract: PURPOSE:To detect information excellently by providing signal detectors which read signals from a specific position on a sheet carrying a document at both breadthwise side positions of a document conveyance path. CONSTITUTION:The signal detectors 13 and 14 are installed at the breadthwise side positions of the document conveyance path and sheets are set normally and upside down in the breadthwise direction of the document conveyance path. Then when the sheets 12 are conveyed as they are, the signal detector 13 on one side, for example, corresponds to the information position of the normal mode setting input card and detects its information signal hole 11. The signal detector 14 on the other side corresponds to the information position of the upside-down mode setting input card and detects its information. Consequently, there is no failure in information detection due to the deviation in the information position of a conveyed mode setting input card from the signal detectors 13 and 14 provided at the information positions of the setting input card.

Abstract: PURPOSE:To stop interference by applying frequency modulation to a voltage controlled oscillator controlled in a phase locked loop with a digital signal and providing a means in duplex communication between a sender side and a receiver side when frequency modulation is applied even to a reference signal oscillator. CONSTITUTION:Two methods are considered to attain full duplex communication by applying frequency modulation to a reference signal.

Concretely, the 1st method consists of a subtractor circuit 33 and a cancel signal generator 32 and an interference signal appearing on a loop filter 11 is cancelled at the circuit 33 by using a signal obtained by the generator 32. The 2nd method consists of a cancel signal generator 37, a 2nd local oscillator 38, a subtractor 39 and either of cancellation lines 40, 41.
