摘要:
An ink jet recording apparatus performing recording by discharging ink onto a recording medium is provided with a conveying belt for conveying the recording medium by the attraction of static electricity, an electrode provided to be in contact with the recording medium conveyed by the conveying belt, and a power source capable of charging the electrode with the charge which has the polarity opposite to the charge carried by the conveying belt. The main droplet and satellite split from the ink droplet are impacted on the recording medium to prevent the adhesion of the satellite to the discharging port of the discharging surface of the recording head, thus maintaining desirable recording for a long time.

An image recording apparatus is equipped with a conveying belt member for carrying a sheet member, a recording head holding member for holding a head for recording on the sheet member, and guide members for supporting and guiding the conveying belt member. The first guide member is provided upstream of the recording head holding member, the second guide is provided downstream of the first guide, and the third guide is provided between the first and second guides. The third guide member displaces the conveying belt member toward the recording head holding member.
摘要:
In an ink jet recording apparatus, recording is performed by discharging ink through discharge ports in a recording head onto a recording medium. Ink flows into a housing from an ink storing portion through an ink inlet portion on an upper surface of the housing. The housing contains an impeller on an end of a shaft. An ink outlet portion of the housing is located tangentially with respect to the rotating impeller to supply ink to the recording head.

Disclosed is a recording apparatus that includes a conveying device for conveying a recording sheet in a conveying direction, a recording device confronting the conveying device for recording an image on the sheet being conveyed and a supporting device for shiftably supporting at least one of the conveying device and the recording device for movement between a recording position where the conveying device and the recording device are in parallel contact with the recording sheet therebetween and a non-recording or separated position where the conveying device is separated from the recording device. In one embodiment, the recording device and the conveying device are separated in parallel in the non-recording position and the supporting device causes the at least one of the conveying device and the recording device to be non-parallel during movement from the non-recording position to the recording position. In another embodiment, during movement of the conveying device from the separated position to the recording position, the supporting device first causes a first end of the conveying device to obliquely shift towards the recording device and thereafter, causes a second end of the conveying device to shift toward the recording device.

There is provided a multiimage forming apparatus for forming image data onto photo sensitive drums by an electrophotographic system. This apparatus comprises: an image forming circuit to form different images onto the photo sensitive drums; a transfer device to transfer the images on the drums onto the same transfer paper; a conveying belt to convey the transfer paper; a control circuit to control the image forming circuit so as to form registration marks to match the positions of the images onto the drums; CCD detectors to detect the recording positions of the marks; and a correcting circuit to correct at least two of the positional direction in the conveying direction of the belt, the positional deviation in the direction perpendicular to the belt conveying direction, the magnification of the image, and the inclination of the image on the basis of the detection outputs of the detectors. With this apparatus, the positional deviations of the images which occur during the image formation can be accurately corrected, so that the images can be accurately formed on the transfer paper by reading and matching the position matching registration marks.
摘要:
A method for forming a negative image comprising imagewise exposing a photographic material to provide exposed areas and unexposed areas, said material comprising, on a support, (1) an emulsion layer containing a light-sensitive silver halide, (2) unsensitized silver halide metallic salt grains which are more soluble in a developer than the light sensitive silver halide, and (3) nuclei for physical development, processing said material in the presence of a reducing agent and a solvent for said grains with said developer containing a substance which renders said grains less soluble by adsorbing thereto, said developer rendering said grains in said exposed areas and not in said unexposed areas soluble in said solvent, whereby metal ions are released and deposited on said nuclei.

摘要:
This invention involves a color photographic material which contains a support and a hydrophilic layer containing a dye image wherein the material contains a compound represented by the following formula: ##STR1## wherein R represents an alkyl group, an alkenyl group, a cycloalkyl group, an aryl group or a heterocyclic ring; R.sub.1, R.sub.2 and R.sub.3 individually represent hydrogen, halogen, an alkyl group, an alkylthio group, an alkoxy group, an aryl group, an aryloxy group, an arylthio group, an acyl group, an acylamino group, a diacylamino group, an acyloxy group, a sulfonamido group, an alkylamino group, a cycloalkyl group or an alkoxycarbonyl group; and Z represents an atomic group or groups necessary for forming a chroman or coumaran ring; provided that R and R.sub.1 can cooperatively be cyclized to form a chroman or coumaran ring.
摘要:
A placing member is configured to be supported from an outside by a terminal electrically connected to a terminal electrode, and an X-axis-direction extended portion, a Y-axis-direction extended portion, and a Z-axis-direction extended portion are provided in the terminal. This configuration provides an angular velocity sensor, in which a problem such that Y-axis-direction and Z-axis-direction vibrations applied from the outside cannot be damped is eliminated, and all the vibrations in three axis directions can be damped.
