    • Data processing can be performed even if a trouble occurs in a hard disk device. If a trouble occurs in a first hard disk device, it is recognized that a spare hard disk device is on standby, and operation of the spare device is checked. The first hard disk device is switched with the spare hard disk device, the data is processed and output. During this process, the first hard disk device is initialized. When the first hard disk device becomes available, the spare hard disk device is switched with the first hard disk device. If the first hard disk device is unavailable, an error is notified to an administrator to request repair or replacement.
    • 即使硬盘设备发生故障,也可以进行数据处理。 如果在第一硬盘装置中发生故障,则认为备用硬盘装置处于待机状态,并检查备用装置的动作。 第一个硬盘设备与备用硬盘设备切换,数据被处理并输出。 在此过程中,第一个硬盘设备被初始化。 当第一个硬盘设备可用时,备用硬盘设备与第一个硬盘设备切换。 如果第一个硬盘设备不可用,则会向管理员通知错误,以请求修复或更换。

    • An image forming apparatus carries out an image processing with respect to a sheet size and image information based on a print request to obtain a write image on a photoreceptor. On the basis of a printing ratio of the write image, the apparatus predicts occurrence of an image elongation. If the apparatus predicts that the image elongation occurs, the apparatus calculates a bending amount of a bended portion based on the difference between peripheral velocities of a photoreceptor and the idle roller, and the apparatus variably controls the peripheral velocity of an idle roller so that the bending amount is adjusted so as not to cause a slip phenomenon. It is possible to avoid the occurrence of a phenomenon of slipping of a sheet with respect to the photoreceptor without lowering image quality, and to surely secure a blank space formed at a rear edge portion of the sheet.
    • 图像形成装置基于打印请求对纸张尺寸和图像信息进行图像处理,以在感光体上获得写入图像。 基于写入图像的打印率,该装置预测图像伸长的发生。 如果该装置预测图像伸长发生,则该装置基于感光体的周向速度与空转辊之间的差异来计算弯曲部分的弯曲量,并且该装置可变地控制空转辊的圆周速度,使得 调整弯曲量,不会产生滑动现象。 可以避免在不降低图像质量的情况下发生片材相对于感光体的滑动现象,并且可靠地确保形成在片材的后边缘部分处的坯料空间。

    • The security of image data is enhanced by utilizing operation keys used in performing image processing and by generating an apparatus-specific encryption key to encrypt the image data with the encryption key. Generation of the encryption key is started when an input is made with a specific operation key. Every input made by operating an operation key on an operation panel is converted into a key code corresponding to that operation key. After sequential repetitions of this process, the key input is finished when an input is made with the specific operation key. The key codes are arranged in the order of operation to generate a key code string, the arrangement of which is then converted. The encryption key is generated based on the key code string.
    • 通过使用在执行图像处理中使用的操作键并且通过生成用于加密密钥对图像数据进行加密的装置专用加密密钥来增强图像数据的安全性。 当使用特定的操作键进行输入时,开始生成加密密钥。 通过操作操作面板上的操作键进行的每个输入被转换成与该操作键相对应的键代码。 在顺序重复此过程之后,当使用特定操作键进行输入时,键输入完成。 密钥代码按照操作的顺序排列以生成密钥代码串,然后转换其安排。 加密密钥是根据密钥代码串生成的。

    • An image recording system includes two image recording apparatuses each capable of recording images independently. A color image recording apparatus is disposed with a bypass transporting path apparatus. A transporting path connecting apparatus is disposed between the front of a monochrome image recording apparatus and the back of the color image recording apparatus. A final processing apparatus that is common to the color and monochrome image recording apparatuses is disposed in the front of the color image recording apparatus. This system includes a process switching portion that switches an image recording process executed by one image recording apparatus to a substitute image recording process of the other image recording apparatus and a switching determining portion that determines whether the switching is executed by the process switching portion, depending on whether a predetermined condition is satisfied.

    • An object of the invention is to allow secure identification of an image forming apparatus from an image on a recording medium on which the black image has been formed, thereby preventing leakage of secret information on the black image securely. A driving roller, a tensioning roller and a supporting member are supported to a frame so as to be movable in upward and downward directions, and a portion spacing mechanism moving an elevating rod in upward and downward directions by rotation of a motor is provided. At a time of the black-image forming process, the driving roller, the tensioning roller and the supporting member are moved downward by the portion spacing mechanism, a transfer conveying belt and transferring devices are spaced from photosensitive drums included in image forming stations for forming magenta and cyan images, and only the image forming process regarding a black image and an image of identification information obtained at image forming stations are made effective.
