Patent number: 6788426Abstract: Record sheets on which an image is formed on the basis of image data supplied from a terminal apparatus, are efficiently discharged to a bin. A post-process section of a digital copier which is used in conjunction with at least first to third computers includes first to third bins, fourth and fifth bins, and a sixth bin, respectively, which are designated for the first, second, and third computers. To each of the bins, a priority of discharging to the bin a record sheet which is to be discharged to another bin is assigned. The section is configured so that, for each of the bins, the number of record sheets housed in the bin can be detected. For example, a record sheet on which an image due to the third computer is drawn is usually housed in the sixth bin. If the sixth bin is full, the record sheet is discharged to one of bins which are not the sixth bin and which are not the first and fourth bins respectively dedicated to the first and second computers, i.e., one of the second, third, and fifth bins.Type: GrantFiled: October 17, 1997Date of Patent: September 7, 2004Assignee: Sharp Kabushiki KaishaInventors: Takashi Yamanaka, Toyoaki Nanba, Tomomi Tanaka, Masao Matsui
