The computer system of the present invention has a plurality of SAS target devices, an SAS initiator device, and a service delivery subsystem that is connected to each SAS target device by means of a physical link that is physical wiring and connected to the SAS initiator device by means of a wide link constituted by a plurality of physical links. The SAS initiator device controls how many physical links in the wide link are allocated to a particular SAS target device, whereby access from the SAS initiator device to the SAS target device is made via a physical link that is allocated to the SAS target device and is not made via a physical link that is not allocated to the SAS target device.

A comparator circuit includes a differential amplifier including load resistors, for amplifying difference between two input voltages of the comparator circuit; an emitter follower circuit for applying positive feedback with respect to a differential amplifier and outputting an output voltage of the comparator circuit; and a grounded-base amplifier, and outputting an output voltage of the comparator circuit, for realizing both voltage output and current output. A grounded-base amplifier includes two transistors each of which has a base supplied with a reference voltage. The differential amplifier includes two load resistors respectively connected to each emitter of the transistors of the grounded-base amplifier. The load resistor flowing a current which is obtained through a collector of the transistor as an output current of the comparator. With this arrangement, it is not necessary to provide a current switch circuit for obtaining current output of the comparator circuit.

Originals are fed onto a platen glass one by one by an automatic original feeder to be read out by a reading system. The originals are converted into digital image data. The image data is transferred to a memory unit. The memory unit is controlled by a CPU. The memory unit is configured of an image memory, a sentence direction recognizing portion, an RAM producing a management table, an original direction (top and bottom direction) recognizing portion, a rotation processing portion, a sign memory and the like. Based on top and bottom directions of original images and directions in which sentences run included in the images, arrangement of images in a 2in1 or 4in1 mode is determined.

An image processing apparatus includes a copying machine and a central processing apparatus provided with a facsimile function. When originals are distributed to a plurality of destinations, a destination list is stored in the central processing apparatus in advance. At this time, as to the destinations to which originals are transmitted through the facsimile, telephone numbers thereof are simultaneously stored. The central processing apparatus controls the copying machine and the facsimile function on the basis of the stored data, so that originals are sent by the facsimile to places to which they should be sent by the facsimile, and also copied originals are sent to places to which they should, respectively.

A dc-stabilized power circuit which has a PNP-type output transistor that is connected between input and output terminals, a base-driving circuit for controlling the driving current of the base of the output transistor in response to the difference between a voltage obtained by voltage-dividing the output voltage from the output terminal and a reference voltage that has been preliminarily determined, and a driving-current suppressing circuit for detecting a voltage between the input and output terminals and for suppressing a driving current released by the driving-current supplying means based upon the result of the detection. The greater the input-output voltage, the further the driving-current suppressing circuit suppresses the driving current from the base-driving circuit to the output transistor, thereby suppressing the output current. Thus, in a dc-stabilized power circuit of a low-loss type which has no current-detecting resistor connected in the output line and which is provided with a control circuit that is constructed as an integrated circuit and that supplies a driving current to the base of the output transistor in response to the output voltage, the power loss due to the output transistor is suppressed to not more than a predetermined level; therefore, it is possible to prevent damage to the output transistor beforehand.

A facsimile apparatus includes a plurality of image reading units, each reading an image and converting the read image into image data, and a main controlling unit for receiving image data through a communication line and transmitting the received image data through another communication line to another facsimile apparatus of a destination. In the main controlling unit of the facsimile apparatus, a selector selects one of the image reading units, and a communication line connection controller connects the main controlling unit through the communication line with the selected one of the image reading units. Further, a data receiver receives image data from one of the image reading units cconnected throught the comunication line by the communication line connection controller.
摘要:
In an image forming apparatus having a two-face copy mode wherein document images are formed on front and back faces of a paper, a direction of an image such as portrait or landscape in a document is set by a user or according to a document size, while a first margin is also set by a size or a document size for a document image on the front face in a reproduced image on a paper. A second margin for another document image on the back face is determined at a position opposite to the first margin. An image memory stores the digital image data. A rotation angle is set according to the document direction and the margin position, so that normal images can be observed in the front and back faces of a paper if the paper is turned over by fixing it at the margin. Then, the digital image data read from said image memory is rotated by the rotation angle. Then, the digital image data is printed on the front and back faces of a paper. If a 2-in-1 copy mode is provided, the rotation angle is determined similarly except the setting or document direction which is set opposite to that of documents for a synthesized image of two document images.

An image forming apparatus comprises a document transport mechanism for transporting a document to a reading station, an image reading unit for reading an image of the document at the reading station and for outputting image data descriptive of the image of the document, a image forming unit for performing an image formation based on the image data, a memory for storing the image data, a data writing unit for transferring and writing the image data to the memory, and a data reading unit for reading the image data from the storage means in readiness for a transfer of the image data to the image forming unit. A control unit is provided for controlling a data write operation, performed by the data writing unit, and a data read operation, performed by the data reading unit, so as to be accomplished independently and in parallel relation with each other.
摘要:
The invention relates to an image reading apparatus for reading images of original documents by moving the original relative to a stationary image reader. A single image reader is used in a first embodiment. When reading the image of a first side, the single image reader is stationary at a first position to read the original. When reading the image of a second side, the single image reader is moved to a second position corresponding to the size of the original, and reads the image of the second side while said image reader is stationary at the second position. The image reading apparatus of the second embodiment uses a stationary first reader for reading a first side of an original, and movable second image reader for reading a second side of an original. The image reading apparatus of the second embodiment changes the positions of the image reader in accordance with the size of the original.
