Title: Separating device, fixing device, medium conveying device and image forming apparatus
Inventor: OSAKI KOJI
IPC: G03G15/20
Filed: 2010-03-17
Abstract: PROBLEM TO BE SOLVED: To solve the following problem: when sheet winds around a heat roller and cannot be separated from the heat roller, jam of the sheet occurs.SOLUTION: In the fixing device 50, the guide roller 42 is provided on the separating claw 41 at a different position from the rotation fulcrum 41b of the separating claw 41, and the spring 43 generates a relatively small biasing force and allows the rotation of the separating claw 41 when the guide roller 42 is forced by the leading end of the sheet P. With such a configuration, the separating claw end 41a moves apart from the heat roller 31 for a short time period when the leading end of the sheet P passes the guide roller 42. As a result, even when the sheet P is not sufficiently separated from the heat roller 31, the separating claw 41 can separate the sheet P from the heat roller 31. As a result, the occurrence of jam of the sheet P can be prevented. Further, the separating claw end 41a is apart from the heat roller 31 each time the sheet P passes the guide roller 42, and therefore deposition of the toner on the separating claw end 41a is not likely to occur. As a result, a surface and a back surface of the sheet P can be prevented from being smeared with the toner.

Title: Input pen holding device and electronic equipment including the same
Inventor: KAWADA YOSHIHIRO
IPC: G06F3/041
Filed: 2010-03-18
Abstract: PROBLEM TO BE SOLVED: To hold an input pen with a simple structure and to reduce costs.SOLUTION: Protrusions 45a and 45b are provided in a pen piston 41 and the protrusions 45a and 45b are engaged with a groove 23 when the input pen 21 is inserted into a pen holding device, and thereby when the input pen 21 is taken out from the pen holding device, the input pen 21 can be stopped at a position where only the vicinity of a rear end 24 protrudes from a first casing 1 (as shown in Fig.5A). In this state, since the input pen 21 is held by the pen piston 41, even if the side 1b of the first casing 1 is directed vertically downward, the input pen 21 rarely falls down by its own weight. Therefore, since the input pen 21 rarely drops on a floor by mistake, damaging to the input pen 21 and scratching of the floor can be prevented.
