Abstract: Disclosed is a print control apparatus that makes it possible to conduct the print controlling operations in the interruption printing mode, so as to optimize the beneficial balance between the interrupting side and the interrupted side. The apparatus includes a job-status parameter acquiring section to acquire job-status parameters including a residual printing time of the first print job, a printing time of the second print job, a first priority degree representing an implementation priority of the first print job and a second priority degree representing another implementation priority of the second print job and a controlling section to determine whether or not the interruption printing operation should be allowed, namely, an availability of the interruption printing operation, based on the residual printing time of the first print job, the printing time of the second print job, and at least one of the first priority degree and the second priority degree.

Abstract: A copy machine including: an original reading apparatus having a front and back surface image reading sensors, being capable of setting plural original documents, feeding out one by one, and simultaneously reading both surfaces of the documents; an image forming apparatus; a post processing apparatus for stapling and/or punching; an image processing section which rotates an image; wherein, a control section controls such that: when the memory capacity for image rotation is enough, the documents are read by the front surface image reading sensor; the obtained image data is rotated; and an image is formed on the recording sheet based on the rotated image data; whereas, when the memory capacity is not enough, an indication to re-set the documents is displayed; the re-set documents are fed out to be read by the back surface image reading sensor; an image is formed based on the image data obtained; and the post processing is executed.

Abstract: Access log storing system (20) to save access history from outside the system as log data having a first memory (70) to save log data, a second memory (80) to also save log data and a storage control device (50) to switch the log data storage destination from memory (70) to second memory (80) in situations where log data cannot be saved I first memory (70).

Abstract: There is described an information processing apparatus, which makes it possible to discriminate the injustice inputting operation from the input error simply committed by the authorized user, in order to prevent the correct password from being illegally found by the injustice intruder. The apparatus includes: a storage section to store a first password, which is represented by a plurality of characters; an input section to input a second password which is represented by a plurality of characters; a comparing section to compare the first password with the second password inputted at the input section; a specifying section to specify a position of unmatched character of the second password when the first password and the second password is unmatched; and a time control section to control time for allowing to input a third password at the input section in accordance with the position specified by the specifying section.

Abstract: Access log storing system (20) to save access history from outside the system as log data having a first memory (70) to save log data, a second memory (80) to also save log data and a storage control device (50) to switch the log data storage destination from memory (70) to second memory (80) in situations where log data cannot be saved I first memory (70).

Abstract: In order to encrypt and decode image data at high speed without providing additional special hardware and placing a heavy load on a CPU, image data 10 is compressed by a compression scheme, and a portion of the compressed data 11 is extracted as encryption key data 12 and the portion, from which the encryption key data 12 is extracted, of the compressed data 11 is changed to zero to convert the compressed data 11 to encrypted data 13. The encrypted data 13 cannot be decoded because data in the beginning portion is corrupted. Moreover, since the decoding of the encrypted data is made impossible by utilizing the property of compressed data, the image data can be encrypted and decoded by a simple processing.

Abstract: The present invention provides a color image reader installed on an image reader such as a hand scanner whose reading speed may change during reading. A hand scanner has an encoder sensor which outputs movement amount data to a relative speed monitoring unit.

Abstract: An image forming apparatus includes: an image reading device for reading an image of a document to obtain image data; a data communication device connected with a computer for receiving an image data from the computer; a facsimile device connected with a telephone line for receiving an image data through the telephone line; an image memory for storing the image data obtained through the image reading device, the image data obtained through the data communication device, and the image data obtained through the facsimile device; an image memory controller for mediating an access to the image memory in a predetermined priority order for storing and reading the image data among the image reading device, the data communication device, and the facsimile device; and an image forming device for forming the image according to the image data controlled by the image memory controller.

Abstract: In an image forming apparatus provided with an image reader to read an image on an image surface of a document and to output image data corresponding to the image; an image processor to process the image data; an image forming device to successively form images on sheets on the basis of the processed image data; there are further provided a post processing device having a stapling stand on which the sheets are placed and a stapler to staple at a predetermined position on the stapling stand, wherein the predetermined position locates at only a single side of the sheet placed on the stapling stand; and a stapling position selector to select a stapling position on the image formed on the sheets, wherein the image processor processes the image data so that when the sheets are placed on the stapling stand, the stapling position on the image formed on the sheets selected by the stapling position selector coincides with the predetermined position on the stapling stand.
