| 20090257803 | GAP ADJUSTING DEVICE AND IMAGE FORMING APPARATUS - A gap adjusting device includes a moving mechanism having a first member supported by a first object so as to be movable along a first axis, and capable of moving the first object in one direction and its opposite direction along a second axis intersecting the first axis according to the movement of the first member in one direction along the first axis relative to the first object, thereby adjusting a gap between the first object and a second object. | 10-15-2009 |
| 20090262160 | IMAGE FORMING APPARATUS - An image forming apparatus includes a moving mechanism having a first member supported by a recording section so as to be movable along a first axis, and capable of moving the recording section in one direction and its opposite direction along a second axis intersecting the first axis according to the movement of the first member in one direction along the first axis relative to the recording section, thereby adjusting a gap between the recording section and a target; a first drive mechanism which moves the recording section supporting the first member along the first axis; and an abutting member which is arranged in a position capable of abutting on the first member by the movement of the recording section, and moves the first member in one direction relative to the recording section by the abutment on the first member. | 10-22-2009 |
| 20090267284 | TRANSPORT DEVICE AND IMAGE RECORDING APPARATUS - A transport device includes a transport path which connects an inlet and an outlet and is formed between a first curved surface which is convex in a first direction, and a second curved surface which faces the first curved surface via a gap, and along which a sheet-like medium is transported, a protruding portion which is arranged on the first curved surface and protrudes from the first curved surface, and a first roller which is arranged on the second curved surface, and at least a portion of which protrudes from the second curved surface. The protruding portion is arranged in a position where the sheet-like medium which has entered the transport path through the inlet contacts the protruding portion prior to the first roller. | 10-29-2009 |

| 20090079773 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus including a pressure chamber filled with fluid, a pressure generating element that is provided on a surface of the pressure chamber that changes the volume of the pressure chamber, a nozzle that is in fluid communication with the pressure chamber that ejects the fluid, and a control unit that generates a maintenance drive pulse for discharging unnecessary bubbles together with fluid from the pressure chamber, wherein the maintenance drive pulse includes a first pulse portion that causes the pressure chamber to expand into an expanded state, a second pulse portion that maintains the expanded state for a predetermined period of time, and a third pulse portion that causes the pressure chamber to contract, wherein the pulse width of the first pulse portion is set to be equal to or smaller than half the Helmholtz resonance period of the fluid in the pressure chamber. | 03-26-2009 |
| 20090079788 | FLUSHING METHOD FOR FLUID EJECTING APPARATUS - A flushing method for a fluid ejecting apparatus that includes a pressure chamber filled with fluid, a pressure generating element on a surface of the pressure chamber that deforms the surface to change the pressure in the pressure chamber, and a nozzle in fluid communication with the pressure chamber that ejects the fluid, the method including repeatedly performing first flushing process a first period; and repeatedly performing a second flushing process with a second period. The flushing processes include causing the pressure chamber to expand into an expanded state, maintaining the expanded state, and contracting the pressure chamber from the expanded state, causing the fluid to be ejected from the nozzle. The amount of fluid ejected from the nozzle in the second flushing process is larger than the amount ejected in the first flushing process. | 03-26-2009 |
| 20090295853 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus that ejects fluid includes: a pressure chamber that is filled with the fluid; a pressure generating element that deforms a wall face of the pressure chamber to change a volume of the pressure chamber; a nozzle that is in fluid communication with the pressure chamber and that is used for ejecting the fluid; and a control unit that generates a drive pulse for controlling the pressure generating element. The control unit is able to generate a maintenance drive pulse for ejecting a bubble together with the fluid from the pressure chamber. The maintenance drive pulse includes a first pulse portion that drives the pressure generating element to cause the pressure chamber to expand into an expanded state and a second pulse portion that causes the pressure chamber to contract from the expanded state. The width of the second pulse portion is equal to or smaller than half the Helmholtz resonance period of the fluid with which the pressure chamber is filled. | 12-03-2009 |
| 20090295854 | FLUID EJECTING APPARATUS - A fluid ejecting apparatus that ejects fluid includes a control unit that generates a drive pulse and a temperature detection unit that detects at least one of an environment temperature and a temperature of a fluid ejecting head. The control unit is able to generate a maintenance drive pulse for ejecting a bubble together with the fluid from a pressure chamber. The maintenance drive pulse includes a first pulse portion that cause the pressure chamber to expand into an expanded state, a second pulse portion that causes the pressure chamber to contract from the expanded state, and an intermediate pulse portion placed between the first pulse portion and the second pulse portion for holding the expanded state of the pressure chamber. The control unit adjusts the width of the intermediate pulse portion on the basis of the temperature detected by the temperature detection unit. | 12-03-2009 |
