The first switchback member provided in the first switchback portion transports two document sheets in mutually different directions and the first switchback member has a first switchback path and a first switchback roller pair each for guiding overlapping two document sheets in the mutually different directions or the same direction. The second switchback member provided in the second switchback portion transports two document sheets in mutually different directions.

A sheet transport apparatus is provided with a processing section having a processing position to process a sheet, and a first roller pair and a second roller pair disposed at the front and back of the processing section to transport the sheet to the processing section at a predetermined velocity. Each of driving transmission mechanisms respectively for driving the first roller pair and second roller pair is provided with a rotary shaft for supporting the roller, a rotary member provided with a circular fit hole to fit with the rotary shaft, and a holder member in which a D-shaped press-fit hole is formed to press-fit to the rotary shaft, and to the rotary shaft are attached the rotary member with the circular fit hole formed therein and the holder member with the D-shaped press-fit hole formed therein. Then, in attaching the holder member and rotary member to the rotary shaft, a concave portion of the holder member is fitted with a convex portion of the rotary member so that the rotary member and the holder member are substantially integrally coupled.By this means, since driving transferred to the rotary member from a driving motor is transferred to the rotary shaft from the rotary member through the holder member, without deforming the rotary member by stress of the rotary member in attaching to the rotary shaft, it is possible to transfer driving of the rotary member to the rotary shaft with reliability, and the transport rollers are capable of transporting the sheet at a stable velocity without fluctuations in rotation.

Provided is a document reading apparatus in which an original document fed by feeding means to contact glass having a predetermined reading position is read by reading means. Then, the document reading apparatus is provided with a guide unit having a guide member for guiding the original document to be fed to the contact glass, and a backup unit to back up the original document to be read, and the guide unit is configured to be able to travel between a close position to near the contact glass and an open position to distance from the contact glass. In the guide unit is formed a concave portion for removably accommodating the backup unit, and the backup unit is configured so that an original document guide face of the guide member and an original document guide face in the backup unit form a continuous guide face when the guide unit travels to the close position.Then, the guide unit is moved to the open position to perform cleaning of the backup unit and contact glass. Further, the backup unit is removed to perform maintenance.

A rinsing water supply system for supplying water to a rinsing unit of a developing apparatus in which photosensitive materials are processed and rinsed. The water supply system includes a pipe having a water supply passage through which water is introduced into the rinsing unit from a water source, a solenoid valve for opening and closing the water supply passage, and signal lines arranged along and integrally with the pipe and adapted for transmitting signals for operating the solenoid valve. This arrangement eliminates the necessity for installation of a signal transmission line independently from the water supply passage, for the purpose of transmitting signals for operating the solenoid valve.

A method for processing a silver halide color photographic material is disclosed, which comprises processing an imagewise exposed silver halide color photographic material comprising a support having thereon at least one silver halide emulsion layer comprising silver chloride or silver chlorobromide containing at least 80 mol % of silver chloride with a color developing solution and thereafter processing the material with a bleach-fixing solution, wherein the bleach-fixing solution contains a ferric complex salt of an organic acid and from about 1.times.10.sup.-2 to about 2 mol of bromide ions and/or from about 5.times.10.sup.-4 to about 5.times.10.sup.-2 mol of iodide ions per liter.The method for processing a silver halide color photographic material according to the present invention is excellent in desilvering ability, and enables rapid processing to be conducted.
摘要:
A method of forming an image comprising, after color developmenmt of an exposed silver halide color photographic material, processing the developed silver halide color photographic material with a bath having a bleaching ability and subsequently with a bath having a bleach-fixing ability, wherein the silver halide color photographic material comprises a support having coated thereon at least one silver halide emulsion layer and at least one pyrazoloazole type magenta coupler represented by the following general formula (A): ##STR1## wherein R.sub.22 represents a hydrogen atom of a substituent; X represents a group capable of being split off upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Za, Zb and Zc each represents a methine group, a substituted methine group, .dbd.N-- or --NH--, one of the Za--Zb bond and the Zb--ZC bond being a double bond and the other being a single bond; when the Zb--Zc bond is a carbon-carbon double bond, the Zb--Zc bond may be a part of a condensed aromatic ring; R.sub.22 or X may also form a polymer including a dimer or more; and when Za, Zb or Zc is a substituted methine group, the substituted methine group may form a polymer including a dimer or more. In accordance with the method of forming an image, desilveration is completed in a short period of time and color photographic images having excellent color reproducibility and fastness are obtained without the formation of magenta stain.

摘要:
An object of the present invention is to provide a technique with which an amount of reducing agent adsorbed to a selective reduction type NOx catalyst provided in an exhaust passage of an internal combustion engine can be controlled to a target adsorption amount. In an exhaust gas purification system for an internal combustion engine according to the present invention, when a reducing agent adsorption amount adsorbed on a selective reduction type NOx catalyst is held at a target adsorption amount, a reducing agent supply amount supplied from a supply apparatus per unit time is controlled to an amount obtained by adding a predetermined amount to a reduction consumption amount, which is an amount of reducing agent consumed per unit time by the selective reduction type NOx catalyst for NOx reduction.
