Title: Image forming device
Inventor: SUZUKI HITOMI
IPC: B41J11/48
Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device, not necessitating a user to retain a sheet paper until the time when a roll paper is retreated to avoid the sheet paper even when the roll paper is located on a common transfer passage, for example, when the sheet paper is inserted. SOLUTION: When a user insert a sheet paper into a sheet paper inserting port 4 under a condition that a roll paper is in a common transfer passage, a sensor S1 detects that and judges that the sheet paper is to be printed next time. Subsequently, the rotation of a fan, not shown in a diagram, is started and air is sucked through a plurality of suction ports 17. The sheet paper is retained at the inserting port by an attracting force generated in this case. Accordingly, the user who has inserted the sheet paper will not be necessitated to retain the sheet paper during the retreating and avoiding operation of the roll paper and is permitted to do some other work.
