摘要:
Disclosed is a copying machine employing a uni-focus projection lens in which the lens and a mirror for changing the conjugates length are driven to move independently according to a set magnification ratio and the focal length of the lens. Either the lens or the mirror is moved by a stepping motor according to a set first magnification ratio and the focal length of the lens. Calculated from the travel of either the lens of the mirror is a second magnification ratio, and the other one of the mirror and the lens is moved according to the second magnification ratio. In another way, first the lens is moved according to the set magnification ratio and the focal length of the lens. Calculated from the travel of the lens is the theoretical conjugate length at the set magnification ratio, and the mirror is moved according to the theoretical conjugate length. In another way, first the mirror is moved according to the set magnification ratio and the focal length of the lens. Calculated from the travel of the mirror is the theoretical lens forward length at the set magnification ratio, and the lens is moved according to the theoretical lens forward length.
摘要:
A copying machine of the scanning exposure type has a device for entering the position on a copy sheet where a copy image corresponding to a document image is to be formed. According to the input from the device, the operation timing of a feeder is controlled which feeds the copy sheet to a position where an image formed by scanning exposure on a photosensitive member is transferred from the member to the sheet, such that the copy image is formed on the specified position on the sheet. When an edition copy mode is set or the image forming position input is given with the setting of this mode, the scanner is controlled to move a distance which permits a shift of the document image as specified by the position input.

A device for cutting a paper web includes a rotary blade assembly, a stationary or non-rotatable blade in cutting engagement with the rotary blade assembly and being retractable from the rotary blade assembly during the cutting engagement therewith, guide members supporting the non-rotatable blade for sliding movement in the direction of the retraction, and the non-rotatable blade being biased into cutting engagement with the rotary blade assembly.
摘要:
To provide a photocatalyst having high selectivity and carrying out a reductive reaction with light having a longer wavelength. A photocatalyst has a structure in which a semiconductor and a substrate are joined, in which the substrate causes a catalytic reaction by transfer to the substrate of excited electrons, which are generated by applying light to the semiconductor.

A data processing apparatus includes an input portion, an output portion, a plurality of compressing/expanding devices which compress data-to-be-outputted inputted from the input portion and expand compressed data-to-be-outputted, a file memory which stores the data-to-be-outputted compressed by some or all of the plurality of compressing/expanding devices, a data discrimination portion which discriminates whether the data-to-be-outputted inputted from the input portion is data including a small amount of information or a large amount of information, and a transfer controller. In cases where it is discriminated by the data discrimination portion that the data-to-be-outputted is data including a small amount of information, the transfer controller transfers the data-to-be-outputted to the output portion through the plurality of compressing/expanding devices operating in parallel. In cases where it is discriminated by the data discrimination portion that the data-to-be-outputted is data including a large amount of information, the transfer controller transfers the data-to-be-outputted to some or all of the plurality of compressing/expanding devices while transferring the data-to-be-outputted to the output portion.

In order to maintain consistency between stored data and an image formed on a recording medium, an MFP includes an HDD to store data, a data designation portion to designate target data to be an output target from the data stored in the HDD, a prohibition portion to prohibit modification or deletion of the target data, and an image forming portion to generate a composite image by combining the target data with positional information indicating a position in the HDD where the target data is stored and to form the composite image on a sheet of paper.

摘要:
An image processing apparatus includes a compression/expansion device capable of compressing and expanding image data in a form of JBIG format, a nonvolatile memory which stores the image data compressed in the form of the JBIG format by the compression/expansion device, a deleting portion which makes image data-to-be-deleted stored in the memory un-restorable by deleting only head data of each plane having restoration information of the data-to-be-deleted.
摘要:
A data processing apparatus includes one or a plurality of input portions, one or a plurality of output portions, a plurality of compressing/expanding devices which compress data-to-be-outputted included in a job inputted from any one of an input portions and expand the compressed data-to-be-outputted, and a job discrimination portion which discriminates whether the job inputted from any one of the input portions is not required to be outputted without delay. Depending on a discrimination result of the job discrimination portion, a controller controls operation assignment of a plurality of compressing/expanding devices and activates assigned compressing/expanding devices for the job.
