<p><P>PROBLEM TO BE SOLVED: To provide a slide rule for calculating the discharge amount of carbon dioxide, which can facilitate simple calculation of the discharge amount of carbon dioxide, reading of a content, and an operation. <P>SOLUTION: A slide rule for calculating the discharge amount of carbon dioxide is configured such that a sheet-shaped inner scale on which items of sources discharging carbon dioxide, and the number, time, or amount of the sources discharging carbon dioxide to be disposed or used are indicated is inserted into an outer scale on which the discharge amount of carbon dioxide is indicated and slid, and the discharge amount of carbon dioxide indicated on the outer scale is read. The outer scale is shaped like a transparent flat sheath with both ends open. A plurality of inner scales are prepared per one outer scale. A group of various types of items of sources discharging carbon dioxide (for example, electrical appliances) and the number, time, or amount of sources discharging carbon dioxide to be disposed or used are indicated on the plurality of inner scales, and the inner scales can be replaced. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
