Title: Display unit for quantity of remaining recording paper
Inventor: ITOU HARUHIKO
IPC: G01D15/28
Filed: 1978-10-17
Abstract: PURPOSE: To display the quantity of remaining roll recording paper all the time while preventing it getting loose by interlocking a potentiometer with a pressure body which comes in pressure contact with the roll at its thickness-direction surface.  
     CONSTITUTION: A decrease in thickness of roll recording paper cause potentiometer 10, combined with direct-current power supply 11 to turn, but when its generated voltage increases above one of threshold levels of Schmitt trigger circuits 12aW12e set to different values, the circuit generates an output of "1". On receiving an input of "0" or "1", post-stage NOT circuits 13aW13e generate "1" or "0" and AND circuits 14aW14e generate "1" only when trigger and NOT circuits both output "1". Outputs of AND circuits are supplied to recording-paper remaining quantity display circuit 16, which display the quantity of remaining recording paper corresponding to the generated voltage of the potentiometer. Further, since a pressure body comes in pressure contact the roll of recording paper, it can be prevented from getting lose for definite paper feed.

Abstract: PROBLEM TO BE SOLVED: To prevent a sagging yarn end from touching the roller of a carrying conveyor by providing a yarn sag preventing member so as to prevent the sagging yarn end from being adhered to a conveyor part. SOLUTION: Brushes 1 are arranged on the upper parts of guide members 3 so as to be almost in contact with each other from both sides to the center to prevent a yarn end Y sagging from a package P from touching a roller R. The brushes 1 are arranged obliquely to the traveling direction of a tray T to minimize the resistance to the traveling of the tray T. The brushes 1 are in contact with the neck Tb of the tray T but not in contact with a bobbin B placed on the neck Tb. When the tray T having the package P placed thereon is carried on a carrying conveyor, the tray T is traveled so as to push open the brushes 1 by the neck Tb. The brushes 1 immediately return to the original state after the pass of the tray T by their own elasticity and keep the mutually contact state. Accordingly, the sagging yarn end Y never touches the roller R.
