Claims

[Scope of utility model registration request]

An arbitrary reduction ratio setting key for arbitrarily setting the reduction ratio in 1% increments, one fixed reduction ratio selection key for selecting and setting one of multiple fixed reduction ratios, and this selection key. A plurality of indicators, one of which lights up when selected by an operation, a storage means in which fixed reduction ratio data containing the fixed reduction ratio corresponding to each indicator are written, and a fixed reduction ratio written in this storage means. A fixed magnification change instruction key that is operated when changing magnification data, a magnification display means that displays a numerical value corresponding to the set magnification, and a magnification that is arbitrarily set when the setting key is operated. A fixed magnification ratio that causes a display means to display a numerical value corresponding to the numeric value, and also causes a predetermined one of a plurality of indicators to light up when a selection key is operated, and has a fixed magnification ratio that corresponds to the lit indicator. The data is read from the storage means, the corresponding numerical value is displayed on the display means, and when the change instruction key is operated, the fixed magnification data corresponding to the numerical value displayed on the display means is stored by operation of the setting key. A copy/reduction magnification setting device comprising: control means for controlling writing in a portion of the means that corresponds to the indicator that is lit at this time.
