In a digital image forming apparatus, in which images of a document placed on a document table are read through scanning by a scanner unit and electrostatic latent images are formed on a photosensitive body in accordance with data as for the images of the document by a laser scanning unit (LSU) arranged under the scanner unit, the upper box body which accommodates the document table and the scanner unit can be easily opened upwards relative to the lower box body which accommodates the LSU, centering around a hinge unit provided at the back side thereof. In addition, the laser scanning unit is placed and positioned on a plurality of bar-like members which are in parallel to the drive axis center of the photosensitive body.

A box body construction of a digital image forming apparatus divided into an upper box body and a lower box body and having a vibration source at least in either one of the box bodies, in which vibrations occurring from the vibration source can be absorbed by vibration suppressing action of elastic members intervened and arranged between the upper box body and the lower box body. Therefore, respective box bodies are not affected by vibrations from the other box body.

A color image forming apparatus provided with an image sensor making outputs for every primary color of light through reading and resolving color images to the three primary colors thereof, can exclude unnecessary developing operation pertaining to other developing agents than one or two kinds of developing agent, by distinguishing the colors based on the output per primary color from the image sensor when the color image is read, executing the developing operation through operating only the developers to accommodate one or two kinds of developing agent in the case the color distinguished at that time is the color possible to be expressed only with one or two kinds of developing agent, on the time of reproducing the color image through repeating the developing operations by a plurality of kinds of developing agent acording to the output per primary color from the image sensor.

An image processor has a transparent plate on which a document is placed, and a document cover which covers the document placed thereon. The document cover moves freely between a closed position at which it covers the transparent plate and the document placed thereon and an open position at which it permits the transparent plate to be exposed. Provision is further made of a document illumination source which moves relative to the document placed on the transparent plate, and an image sensor which receives light irregularly reflected by the document that is illuminated by the document illumination source. The image processor further has a document detector which detects the region of the transparent plate where the document exists based on an output signal from the image sensor. The document covering surface of the document cover has a regular reflectance of from 1.5 to 40% and gives a relative intensity of irregularly reflected light as received by the image sensor of from N2.5 to N8.5 in terms of lightness in the Munsell color system. The document detector discriminates whether a document exists on the region of the transparent plate or not in a different manner depending upon whether the document cover is at the closed position or whether the document cover is at the open position.

A variable delivery compressor containing a plurality of compression chambers and reciprocatory compression pistons is adapted for use in an air-conditioning circuit of a vehicle. The compressor has a suction chamber communicating with the compression chambers by way of a plurality of suction valves, some of which are capable of being deformed by a valve pressing mechanism from a first position, where the refrigerant is compressed, to a second position where the compression of the refrigerant is partially ineffective. The valve pressing mechanism contains an axially movable spool actuated by an actuating unit controlled by a cooling-load responsive control unit.

An image scanning device of the present invention includes a platen, an image scanning part that scans an image on the manuscript, a light source that irradiates light from the back side of the platen, a platen cover that is allowed to be positioned in a closed state or in an opened state, a light receiving part that is configured to receive light from the manuscript scanning area on the back side of the platen, a range obtaining part that is configured to obtain range between the amount of received light of the light receiving part in the opened state of the platen cover and the amount of received light of the light receiving part in the closed state of the platen cover, and a manuscript detecting part that is configured to detect existence of the manuscript in a manuscript scanning area of the platen based on the range.
摘要:
A reliable optical transmission system with an improved signal control mechanism that avoids abrupt power variations of light beams, thereby preventing optical supervisory channel (OSC) signals from experiencing errors. An optical amplifier amplifies main signals under the control of an optical amplifier controller, which spends a first predetermined time to raise the output power of the optical amplifier up to a desired level. A pump light source produces a pump beam for injection to a fiber-optic transmission line so as to make it serve as an amplifying medium. The pump light source is controlled by a pump light source controller that spends a second predetermined time to raise the pump beam to a desired power level. This stepwise start-up process of the amplifier power and pump beam power prevents OSC signals from experiencing abrupt power variations.

In a horn antenna apparatus for use in an antenna system for radar, some of the excited radio waves in a TE11 mode in a radio-wave input portion 1 are converted to those in a higher mode in a waveguide portion 5. As the inclination of a line of intersection S of the waveguide portion 5 is not fixed but continuously varied, the higher mode such as a TM11 mode and TE12 mode and the like is excited everywhere in the direction of the axis Z of the waveguide portion 5. Then the configuration of the line of intersection is determined so that an amplitude and a phase as the generated quantity of higher mode such as the TM11 mode generated in the waveguide portion 5 conform to desired values with respect to each higher mode.

A variable displacement refrigerant compressor of the variable angle wobble or swash plate type is disclosed. The compressor according to the invention has a displacement control valve which is operable in response to the evaporator pressure so as to restrict the drop thereof by throttling the refrigerant gas flowing through a control port disposed between the evaporator and suction chamber. Crankcase of the compressor is arranged for direct communication with the evaporator so as to keep the crankcase under a pressure which is substantially the same as the evaporator pressure.
