  • Cleaning sheet for a paper feeding device
    Patent number: 5616386
    Abstract: The present invention is intended to provide a cleaning sheet which is easy to handle and effective to clean a picker roller. A cleaning sheet coated with a cleaning adhesive is placed in a paper feeding cassette. A picker roller rotates thereby being cleaned with the cleaning sheet. The sheet has a certain stiffness so as not to disengage from a claw of the cassette when the picker roller rotates. The sheet is composed of a base sheet with a coat of cleaning adhesive and a releasable cover sheet. The base sheet and the releasable cover sheet are cut off by specified portions allowing for the multiple use of the sheet. A higher cleaning effect is obtained by using an adhesive containing abrasive grains as a cleaning adhesive applied onto the cleaning sheet.
