Title: Subscriber circuit
Inventor: ISHIZAWA AKIRA
IPC: H04Q3/42
Filed: 1984-03-02
Abstract: PURPOSE:To make a current supply circuit operable and to enable use of two-lines/four- lines conversion circuit in the current supply circuit by controlling a DC feedback circuit in the current supply circuit, by slowing down rise and fall waveforms of feeding, by transmitting a smooth charging pulse and simultaneously by conducting a current between both current supply circuits at the time of the off condition. CONSTITUTION:A current supply circuit detects a voltage across terminals A and B, constituted of operation amplifiers OPA and OPB and feeding transistors TRA and TRB through a DC feedback circuit DC and feeds a direct current with respect to the side of a telephone set by driving a constant current circuit. By controlling a DC feedback signal from a DC feedback control terminal CDC, current feeding is controlled. Two units of current supply circuits are reverse-polarity-connected each other, thereby constituting a subscriber circuit. Since a constant current runs as a minimum current even when a current passing in call lines LN1 and LN2 is zero, an operation can be possible irrespective of the presence or absence of current feeding and that of a current running in a call line. Moreover, reduction filters FIL(N) and FIL(R) are installed, a change in a current control signal is smoothened and the signal is impressed to a current feedback control terminal.

IPC: B65H1/26
Filed: 1985-03-04
Abstract: PURPOSE:To enable a cassette to be easily set by allowing a tongue to be automatically swung accompanied with the movement of a base plate in a device of a copying machine as referred to the titled. CONSTITUTION:When a feed cassette 6 is exchanged, a base plate 10 is pulled toward you, then, both a stationary rack 5 and a pinion 13 are activated allowing a traveling rack 15 to move to the right. This causes a spring 16 to be contracted allowing an arm 17 to swing clockwise with center at a shaft 18. This permits a tongue 19 to swing to the same direction, accordingly, the state of being pressed on the part of a support 7 of a copying machine 6 is released permitting a form to separate from a feed roller 8. Subsequently, when a cassette which is fed with forms, is fitted allowing the base plate 10 to be inserted, each of sections starts operating reversely allowing the tongue 19 to raise up the support plate 7 of the cassette 6. This permits the form to be automatically pressed to the feed roller 8 with pressure. This configuration enables the cassette to be easily set.
