Patent JP-S57180541-A (JP)
Title: Paper handling unit
Inventor: ISHIDATE YOSHIYUKI
IPC: B65H3/64
Filed: 1981-04-27
Abstract: PURPOSE:To handle the paper reliably by means of a simple constitution under changes of various conditions by blowing the hot air at the copying paper to make them uneven at an automatic paper-feed unit of a copying machine which blows the air at the end face of the stacked paper to handle the paper. CONSTITUTION:The hot air is blown at the end face 14 of the stacked copying paper 12. Thereby, the copying paper, particularly the protion near the end face 14 of the uppermost sheet is somewhat dried due to the heat and is made uneven, reducing the adhesion among the stacked paper, therefore separation of each sheet can be improved. Accordingly, even if the environmental temperature, humidity, distance between the paper end and an air blow port, blowing pressure, paper quality, etc. are changed, the paper can be handled reliably.

Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To improve the operability of the changeover of a communication mode by providing a remote changeover means for switching the communication mode to a data communication mode in the case of receiving a changeover instruction to a data communication priority mode when the communication mode is a telephone priority mode. SOLUTION: When a call is terminated or originated in a TEL priority mode, after a line is closed, whether or not the value of a remote changeover permission flag F is '1' is judged. In the case that it is not '1', TEL communication is continued. In the case that the value of the remote changeover permission flag F is '1', since it is the state where the remote changeover of the communication mode is permitted, whether or not the changeover instruction to a FAX priority mode is present is checked through a printer interface 15 or a scanner interface 16. In the case that the changeover instruction is present, the communication mode is switched to the FAX priority mode and transition to FAX communication thereafter is performed.
