Title:
【発明の名称】自動給紙装置
Document Type and Number:
Japanese Patent JP2513714
Kind Code:
B2
Abstract:
Successive sheets are drawn from a magazine by a gripper which is movably mounted on a drum-shaped rotary conveyor and serves to transfer successive sheets into a gathering machine. The position of the gripper with reference to the conveyor is indicative of the thickness of the sheet or sheets which are transported from the magazine, and such position is ascertained by a monitoring device in cooperation with an input element which is movable with the gripper. The input element can constitute a soft iron core which extends into a coil of an oscillatory circuit constituting the monitoring device, a plate which extends between the plates of a capacitor forming part of the monitoring device, or an arm for a disc bearing encoded information which is monitored by a photoelectronic transducer. The monitoring device transmits signals to a circuit which is adjacent the path of movement of the gripper and includes the transducer or a winding cooperating with a winding of the oscillatory circuit. Signals from the winding or from the transducer are processed by an evaluating circuit and are used to regulate the speed of the conveyor.
