Abstract
The present invention relates to a device for guiding a paper toward a transfer region disposed in the vicinity of a sensitive member. A lower guide comprises at least two elastic members, the at least two elastic members being adapted to change elastic modulus depending upon a rigidity of the paper being conveyed toward the sensitive member, whereby the paper can be guided toward the sensitive member under the best condition, regardless of the quality of the paper.
Claims9
A device for guiding paper toward a paper transfer region and a sensitive member, said device comprising:
- an upper paper guide to be disposed adjacent the sensitive member;
- a lower paper guide to be disposed below the upper paper guide, said lower paper guide comprising at least two elastic members, each said elastic member having a predetermined modulus of elasticity such that said lower paper guide adapts its overall elasticity according to the rigidity of a paper transferred toward said transfer member, and at least portions of said elastic members contacting the paper when the paper is transferred having the properties of an electrical insulator.
A guide device for guiding a paper in conjunction with an upper paper guide member toward a sensitive member in an electrophotographic copying machine, said guide device comprising:
- a lower paper guide member to be disposed below the upper paper guide member such that the upper and lower paper guide members receive a paper to be transferred toward the sensitive member therebetween;
- and
- resilient means disposed on said lower paper guide member for biasing a paper transferred between the upper and lower guide members in a substantially upward direction, said resilient means having a variable spring constant variable with the rigidity of the paper being transferred, said resilient means comprising at least two elastic members.
