摘要:
In the sheet conveying apparatus, convey force of a convey device is changed according to the load applied to a recording sheet in order to constantly convey the recording sheet reliably. A rotary sheet discharge body has convex and concave portions in order to reliably discharge the recording sheet regardless of resistance applied to the recording sheet. Highly frictional material is provided only around the end portions of the rotary sheet discharge body in order to reduce the manufacturing cost and improve the facility of assembly.

A coating apparatus which comprises a feeding means to feed a coating liquid, a coating liquid applicator having a slot extending in one direction to discharge the coating liquid fed by the feeding means, and a conveying means to move at least either the coating liquid applicator or a substrate to be coated with the coating liquid relatively one to the other, comprising: (a) a first control means which comprises (a-1) a position detecting means to detect positions of the coating liquid applicator or the substrate which is moved by the conveying means, and (a-2) a controller capable of stopping the coating liquid applicator or the substrate which is moved by the conveying means at a position detected by the position detecting means such that a start-of-coating line of the substrate is in register with the slot of the coating liquid applicator and capable of starting the movement of the coating liquid applicator or the substrate which is stopped at the position; and (b) a second control means which comprises a timer controller capable of transmitting a signal to the controller of the first control means for the movement of the coating liquid applicator or the substrate which is stopped at the position after a desired period which begins with commencement of feeding the coating liquid and is needed for forming a coating liquid bead which is in contact with both the exit aperture of the slot of the coating liquid applicator and the substrate at the start-of-coating line.

An ink jet recording apparatus having an image recording area for performing image recording onto a recording medium includes a head holding portion for holding an ink jet recording head, a platen, and a recording medium exhausting device. The platen has planar and facial sections. The planar section supports the recording medium opposed to the ink discharge ports in the image recording area. The facial section is disposed downstream of the image recording area with respect to a conveyance direction of the recording medium, and extends in a direction away from the ink discharge ports toward the conveyance direction. The planar section and the facial section are continuous, and the angle between the extension of the planar section and the facial section is from 3.7 to 7.5 degrees. The recording medium exhausting device, disposed downstream of the facial section of the platen in the conveyance direction, exhausts the recording medium from the recording area by guiding the recording medium from the extension of the planar section of the platen in a direction closer to the facial section of the platen.
摘要:
In a serial recording apparatus having three recording modes, i.e., normal, high-quality, and high-speed recording modes, sheet feed control satisfying requirements in these modes is performed. More specifically, high-speed sheet feed control is performed in the normal or high-speed recording mode, and low-noise sheet feed control with improved precision is performed in the high-quality recording mode, although the speed is low. The apparatus can include a sheet feeder, a designator, a selector and a controller. The sheet feeder feeds a recording sheet relative to a recording head. The designator designates one of the recording modes. The selector selects one of a plurality of patterns for driving the sheet feeder in accordance with the designated recording mode. The controller controls a moving speed of the sheet feeder in accordance with the selected pattern for driving the sheet feeder.

A container for safekeeping an ink jet cartridge is provided with the main body of a container for storing an ink jet cartridge having a recording head unit, and an ink tank unit containing ink to be supplied to the recording head unit, a lid element for covering the inlet and outlet of the main body of the container for storing or removing the ink jet cartridge, an elastic cap member provided in the main body of the container for covering the recording head unit. This container for safekeeping an ink jet cartridge comprises a rib arranged on the inner wall surface of the lid element for exerting pressure on the recording head unit of the ink jet cartridge to press it to the elastic cap member; and a recess arranged on the inner wall surface of the main body of the container in a position corresponding to the location where the elastic cap member is arranged. In this way, it is possible to cap the recording head appropriately in the container to provide a highly reliable safekeeping of the ink jet cartridge, and at the same time, to store and safekeep the ink jet cartridges for monochromatic use and color uses exhangeably.
摘要:
A recording apparatus having a memory for storing recording data, and an address counter for controlling addresses in the memory in the direction of the columns or rows. The address counter controls a read start address for starting a process of reading the memory, thereby compensating for deviations in the longitudinal or widthwise direction of recording paper.
摘要:
The present invention provides a polishing fluid composition which can effectively polish a surface of a semiconductor silicon wafer or a surface of a film comprising silicon to be formed on silicon wafers with a markedly reduced amount of colloidal silica to be used as abrasives, or a polishing fluid composition which is particularly useful for a polishing step after removal of an oxide layer in a two-step polishing method. The former polishing fluid composition comprises an alkaline suspension which contains a water-soluble silicic acid component, colloidal silica and an alkaline component, and which has a pH value of 8.5 to 13. Meanwhile, the latter polishing fluid composition comprises an alkaline solution which contains a water-soluble silicic acid component and an alkaline component, and which has a pH value of 8.5 to 13; and is substantially free of abrasive particles.

A recording apparatus includes a carriage capable of mounting and removing a head member, one side portion provided with a positioning unit for the carriage unit to position the head member, a head holding unit for holding the head member, being relatively movable with respect to the one side portion, an operational unit that engages with the head holding unit to move such head holding unit relatively with respect to the one side portion, a first biasing device for biasing the operational unit in the same direction as that in which the head holding member approaches the one side portion, a stopper arranged on the carriage for regulating the biasing force of the first biasing device in a given position, at the same time, causing the biasing force of the first biasing device not to be exerted on the operational unit in the given position, and a second biasing device for biasing the head holding unit in the direction in which such unit parts further away from the one side portion. With the structure thus arranged, a recording head can be removed from the carriage without any additional power from the user or the like once the operational unit is allowed to move to a given position where the stopper acts. The head removal is reliably executable just by one action.
