Title: Copying machine with original carrying device
Inventor: TAMIYA YOSHIYUMI
IPC: G03G21/00
Filed: 1984-05-29
Abstract: PURPOSE:To prevent erroneous operation by setting the interruption mode in accordance with an interruption mode setting command and displaying ''1'' in an original number display means at an interruption mode release time if repeated copying is stopped on the way because of setting of the interruption mode. CONSTITUTION:A control means 1 sets immediately the interruption mode by the interruption mode setting command from an operation means 2. When the interruption mode is set, a discriminating means 3 discriminates whether repeated copying of a set number of copies for an original in an exposure position is performed or not. If repeated copying is performed, a means 4 displays ''1'' on a recopy original number display means 5 at the interruption mode release time. Since the interruption mode is set immediately by the interruption mode setting command from the operation means 2 in this manner, interrupt copying is perfromed urgently. Since ''1'' is displayed on the recopy original number display means 5 at the interruption mode release time if repeated copying is stopped halfway at the interruption mode setting time, an operator discriminates whether repeated copying before interruption is completed or intermitted.
