Title: Automatic document conveying device
Inventor: TARUKI TAKASHI
IPC: H04N1/00
Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To suppress the skew conveyance of a document so as to reduce bent conveyance by taking out a document while pressing it by an elastic member in taking out the document from a document placing table by a separative conveying means. SOLUTION: A polyester film 7 with a thickness of 0.1-0.2 mm is partially bonded to the inside of an outer cover 6 and inclined downstream, and the film 7 and a lead- out roller 8 are arranged on a straight line in a conveying direction. The tip part of the film 7 is not in contact with a pressing member 4 in a continuous line position when a document is not placed, but is elastically deformed in contact with the document in a broken line position when the document is fed. The friction coefficient of the film 7 with the document is made slightly higher than the mutual friction coefficient of the documents and considerably lower than the friction coefficient of the roller 8 with the document, so that there is no interference when the document is placed.  Since contact resistance between the pressing plate 4 and the film 7 is small, even if the pressing plate 4 and the film 7 come in contact when the document is not placed, there is no interference when the document is placed. A cross direction skew generated by the deviation of the document abutting position of the roller 8 can be suppressed by the contact of the film 7.

Abstract: PROBLEM TO BE SOLVED: To enable a user to apply the power of the hand with ease for washing more efficiently by providing a section inclined as specified in the inner wall on this side of a washbowl in a washing stand comprising a cabinet and a washbowl fixed on the cabinet. SOLUTION: In a washing stand comprising a cabinet 1 and a washbowl 2 fixed on the cabinet 1, an inclined section 5 with the inclination being 30-45 degrees relative to the floor is formed in the inner wall on this side of the washbowl 2. When the inclination is steeper than 45 degrees, the washing will easily fall to the bottom of the washbowl 2 for producing a long distance from the washing person, forcing the person to take an unnatural attitude with which it is difficult to exercise power properly. When the inclination is gentler than 30 degrees, the water will easily flood over the inclined section 5. Accordingly, the inclination should be in the range of 30-45 degrees, where the washing person can keep the washing nearer and apply power easily to remove stains from the washing without taking any unnatural attitude.
