| 20090085994 | LIQUID DISCHARGING APPARATUS - The image forming apparatus includes a liquid discharging head that discharges a liquid; and a damper chamber that is provided in a liquid supply flow channel, the damper chamber being an internal space that is formed by bonding a flexible member to a base member, wherein the flexible member has a bonding surface that is bonded to the base member, an opening that is formed in the bonding surface, and a swollen portion that is three-dimensionally swollen from the edge of the opening to form the damper chamber, the base member has a communicating port, through which the damper chamber and the liquid supply flow channel communicate with each other, in a state where the base member is bonded to the bonding surface of the flexible member and closes the opening, and the flexible member is disposed such that the swollen portion is swollen in a gravity direction. | 04-02-2009 |
| 20090245907 | IMAGE PROCESSING DEVICES AND SHEET FEEDING DEVICES - An image forming apparatus including an image forming portion that forms an image on a surface of a sheet, a feeding device that feeds the sheet in a sheet feeding direction, a sheet receiving portion, and an engagement portion selectively moves between a first position and a second position. When the engagement portion is in the first position, the engagement portion engages the leading end of the sheet. When the engagement portion is in the second position, the engagement portion does not engage the sheet. When the engagement portion is in the first position, the engagement portion engages a leading end of the sheet before a trailing end of the sheet passes the feeding device. The sheet receiving portion receives the sheet after the engagement portion engages the leading end of the sheet. | 10-01-2009 |
| 20100122460 | CHANNEL FORMING METHOD, CHANNEL FORMING BODY, AND ASSEMBLY PARTS OF THE CHANNEL FORMING BODY - A channel forming method includes: forming a first member having a fitting groove and a second member which is to be fitted into the fitting groove; fitting the second member into the fitting groove; and joining joint peripheral portions of the first member and the second member by heating from outside the fitted second member, and a channel is foamed by channel grooves formed in a bottom portion of the fitting groove and a facing surface of the second member facing the bottom portion. | 05-20-2010 |
| 20100123765 | LIQUID JETTING APPARATUS AND LIQUID SUPPLY UNIT OF LIQUID JETTING APPARATUS - A liquid jetting apparatus includes a liquid jetting head; a liquid supply channel which supplies the liquid to the liquid jetting head; an air discharge mechanism which discharges air existing in the liquid, the air discharge mechanism including an air storage portion, an air discharge passage, a valve, and a flexible member. When a negative pressure is generated in the air discharge passage, the flexible member is deformed to open the valve, and to discharge the air inside the air storage portion via the air discharge passage. Accordingly, the size of the apparatus can be made small while making it possible to discharge the air accumulated in the head unit. | 05-20-2010 |
