PURPOSE:To prevent copying mistake by allowing a start key for starting operations to discriminate whether copying is available, it is available on a reference condition, or it is available when a setting mode, etc., is changed, and to display a discriminated result. CONSTITUTION:When the copying start key 2 on an operation panel 1 being an operation part is depressed and contact points 3a and 3b come in contact with each other, a signal enters into a CPU and the copying is started. A lamp group 4 using green, red and yellow miniature lamps is arranged under the copying start key 2 in order to illuminate the copying start key 2 and is switched according to the condition of this device. Namely, whether the copying is unavailable, it is available on the reference condition, or it is available on a condition different from the reference condition such that the setting mode, etc., is changed is distinguished and the discriminated result is displayed. Thus, miscopying can be prevented. |
