An image forming system according to another embodiment of the present invention includes an image forming apparatus that prints an image on recording paper, an air cleaner that is for cleaning air, and is integrally attached to the image forming apparatus via a support member, and supported above the image forming apparatus by the support member, and a control unit that causes a display unit of the air cleaner to display an operating state of the image forming apparatus.

Abstract: An image forming system is provided with an Image Forming Operation Unit, an Air Cleaning Operation Unit, a power source, and a Control Unit. The Control Unit has a coordinated OFF control function of coordinating a first power supply OFF control for turning off power supply from the power source to the Image Forming Operation Unit and a second power supply OFF control for turning off power supply from the power source to the Air Cleaning Operation Unit, and the coordinated OFF control function is configured to execute the second power supply OFF control when a preset time period elapses after executing the first power supply OFF control. Also, in the image forming system, an air cleaning operation of an air cleaning apparatus is stopped when an image forming apparatus is set to an a night mode or when a fixed time period elapses after the night mode is set. The air cleaning operation of the air cleaning apparatus is restarted when the image forming apparatus is resumed from the night mode.

Abstract: A paper feed cassette incorporates a storage portion for standard-sized paper and a storage portion for small-sized paper that has an area smaller than the standard-sized paper, further includes paper conveyance paths for guiding the standard-sized paper and small-sized paper from the respective storage portions to an image forming portion, and these paper conveyance paths share a common vertical portion.

Abstract: In response to a contents data transmission request from a user terminal, a contents storage server encodes a contents data meeting the transmission request by vector coding or hierarchical coding and transmits the encoded contents data to the user terminal. The user terminal having received the encoded data notifies a charging server of information on a resolution selected by the user and then receives information needed for a corresponding decoding process from the charging server. The charging server carries out a charging process based on the received information on the resolution.

Abstract: An image reading device has a movable platen glass that is rotatably supported, that is substantially a prism having a plurality of read faces, and that is constructed so that rotation of the platen glass can switchably place one of the read faces in the read position. Therefore, even if the platen glass becomes stained, the image reading device makes it possible to start or continue reading document images without requiring labor and time for cleaning the platen glass.

Abstract: An improved document reader is provided, including: a platen for an original document to be placed thereon; and a hold-down member capable of opening and closing relative to the platen and operative to press the original document against the platen so as to make the original document stationary when in a closed state, wherein: the hold-down member includes a plurality of pressing sections arranged adjacent to each other, the pressing sections having respective grips which, except the grip, are engageable with respective notches defined by the pressing sections, respectively.

Abstract: As for read-out image data of a manuscript, image regions not requiring color output are specified as specified regions 1 and 2. Then, it is determined whether the color information of the pixels of the read-out image data outside the specified regions 1 and 2 is achromatic. When it is determined as achromatic, the read-out manuscript is determined as a monochrome manuscript, so that processed image data in which chromatic pixels of the read-out image data in the specified regions 1 and 2 are converted into achromatic pixels is outputted as achromatic (monochrome) data. On the other hand, when it is determined as not achromatic, the read-out manuscript is determined as a color manuscript, so that the read-out image data is outputted intact as chromatic (color) data.

Abstract: When handle region(s) of disengaging lever(s) is/are pulled in direction(s) tending to cause disengagement of engagement between access-controlling body or bodies and main body housing(s), respective action edge(s) of rotating region(s) may rotate about shaft(s) in direction(s) tending to cause disengagement of engagement. Upon rotating in direction(s) tending to cause disengagement of engagement, respective action edge(s) of rotating region(s) may press on and impel support plate(s) of main body housing(s). In accompaniment thereto, disengaging lever(s) may move upward, and respective downwardly directed engagement projection(s) of access-controlling body or bodies may be lifted up and extricated from respective upwardly directed engagement projection(s) of main body housing(s).

Abstract: Print is made on a recording paper by running an ink carriage along the supporting axis in a reciprocating motion. The ink carriage includes ink heads respectively provided with a front ink nozzle and a back ink nozzle facing their respective directions, so that print is made simultaneously at two portions on the recording paper along the transportation direction in which the recording paper is transported through a single transportation path one by one. Consequently, there can be provided an ink jet printer which can improve printing efficiency by increasing a printing rate and printing resolution, and realizing printing of an overstrike character, simultaneous printing of mixed information, double-side printing, etc.

Abstract: When a standby state is released, the attitude detector detects its own attitude, and a display style of key identification images assigned to the respective input keys and an image to be displayed on the display unit is determined based on the detection result. Then, set values fitting the display style are read from a display table and a key arrangement table, and switching of control is performed. Next, when switching of control is determined to be completed, the key identification images and output image are displayed in the set display style, and the display direction is optimized. Thus, the display style of the key identification images that are indicators for identifying input keys and the output image displayed on the display unit is automatically optimized according to the attitude.

Abstract: An image-forming apparatus is provided which includes a document reading section for reading image information from a document, and an image-forming section for forming an image on a sheet of paper based upon the image information of the document read by the document reading section. A space section is formed below the document reading section, which accommodates the image-forming section and serves as a discharge section to which the sheet of paper bearing the image formed in the image-forming section is discharged. The space section is surrounded by peripheral walls of an apparatus main body including the image-forming section. The image-forming apparatus further includes a paper post-treatment section that subjects the sheet of paper bearing the image to post-treatments, such as an adjustment process and a stapling process, in a virtually horizontal state, and that is placed between the document reading section and the space section.
