    • An image forming device forms an image on a recording sheet by bidirectional recording. In the image forming device, a control part controls the image forming device. The control part includes a distance changing part that changes a sheet transporting distance for transporting the recording sheet after a forward movement of a recording head to a first transport distance and changes a sheet transporting distance for transporting the recording sheet after a backward movement of the recording head to a second transport distance, and a nozzle changing part that determines inactive nozzles which do not discharge a recording liquid among nozzles of the recording head alternately for one of the forward movement and the backward movement of the recording head.

    • A secure processing device having a power saving mode, which is used for built-in apparatuses, calculates a hash value of secure data that needs to be saved when switching to the power saving mode, stores the calculated hash value in a protection storage unit whose data is not lost even in the power saving mode, encrypts the secure data and stores the encrypted data in an external memory when switching to the power saving mode. When switching back to the normal power mode, the secure processing device decrypts the encrypted data, calculates a hash value of the decrypted data and compares the hash value with the hash value stored in the protection storage unit. The decrypted data is restored to the protection storage unit when the hash values are identical, but discarded together with the encrypted data stored in the external memory when the hash values are not identical.
    • 具有省电模式的安全处理装置,用于内置装置,计算切换到省电模式时需要保存的安全数据的哈希值,将计算出的散列值存储在保护存储部中, 即使在省电模式下数据也不会丢失,在切换到省电模式时,加密安全数据并将加密数据存储在外部存储器中。 当切换回正常功率模式时,安全处理装置解密加密数据,计算解密数据的散列值,并将哈希值与存储在保护存储单元中的散列值进行比较。 当哈希值相同时,解密的数据被恢复到保护存储单元,但是当哈希值不相同时,被解密的数据与存储在外部存储器中的加密数据一起被丢弃。

    • An image forming apparatus includes a plurality of image carrier rollers placed on an inner circumferential side of an annular conveying path so as to face the annular conveying path and so as to be juxtaposed in a sheet conveying direction along the annular conveying path. Opposed rollers are provided on the outer circumferential side of the annular conveying path. The respective image carrier rollers and the opposed rollers which are in pressure contact therewith constitute pairs of transfer rollers, respectively. Imaging sections for forming intrinsic color images on surfaces of the respective image carrier rollers are provided. A sheet is introduced to the annular conveying path and is conveyed along the sheet conveying direction sequentially through nip sections of the pairs of transfer rollers, while the images formed on the surfaces of the respective image carrier rollers by the imaging sections are transferred one by one onto the sheet. The sheet with the images transferred thereon is released from the annular conveying path.
    • 图像形成装置包括:多个图像承载辊,其设置在环形输送路径的内周侧,以便与环形输送路径相对并沿着环形输送路径沿片材输送方向并置。 相对的辊设置在环形输送路径的外周侧。 与其压接的各个图像承载辊和相对的辊分别构成成对的转印辊。 提供了用于在各个图像承载辊的表面上形成固有彩色图像的成像部分。 将片材引入到环形输送路径中并沿着片材输送方向顺序地通过成对的转印辊的夹持部分传送,同时通过成像部分形成在各个图像承载辊的表面上的图像被一个接一个地转印 到纸上 具有转印在其上的图像的纸从环形输送路径释放。
