Abstract: Through the present invention, an image can be formed in which the ink or toner used is properly displayed, without falsification or fraudulent display, even in the case of a printed matter which includes a specific image indicating information relating to ingredients of the ink or toner. An image forming portion (105) of an image forming device (100) forms an image on a recording medium on the basis of image data for forming an image. A specific-image determining portion (106a) distinguishes whether a specific image indicating information relating to ingredients of ink or toner used to form the image is included in the image data for forming the image. A specific-image substitution processing portion (106b) substitutes the specific image with a predetermined ingredient label mark for indicating ingredients of the ink or toner used by the image forming portion (105) when it is determined by the specific-image determining portion (106a) that the image data for forming the image include a specific image.

Abstract: A document reading apparatus includes an integral display portion integrally provided with the area sensor portion and a main CPU for controlling screen display of the integral display portion, in which reflection light from an object placed on a screen of the integral display portion is detected by the area sensor portion. Based on an area of reflection light from the object detected by the area sensor portion, the main CPU determines whether or not the object is a document, and when determined that it is a document, it sets a document reading mode for reading the document placed on the screen by the area sensor portion.

Abstract: An ion generator for generating positive ions and negative ions is externally attached above a main body of an image forming apparatus. A ratio between positive ions and negative ions which are generated by the ion generator is switched between two ratios in accordance with whether the image forming apparatus is in an operating state or a standby state so that more negative ions are emitted during the operating state. This makes it possible to suppress an effect of an exhaust gas which contains chemical emissions such as an odor and a VOC and which is discharged from the image forming apparatus and to purify an indoor air.

Abstract: A document reading apparatus includes an integral display portion integrally provided with the area sensor portion and a main CPU for controlling screen display of the integral display portion, in which a document placed on a screen of the integral display portion is read by the area sensor portion. The integral display portion has an operation area for displaying various operation keys of the document reading apparatus on its screen, and the main CPU detects an area of the document placed on the screen by the area sensor portion and sets an area other than an area where the document is placed as the operation area of the document reading apparatus.

Abstract: A paper clip removing device capable of removing a paper clip made of a shape memory alloy, that has such a shape that a plurality of documents are bound at a normal temperature and a document bundle is released in a heated state, when the paper clip is on any positions on an end side of a document is provided. When a paper clip made of a shape memory alloy, that has such a shape that a plurality of documents are bound at a normal temperature and a document bundle is released in a heated state, is removed, the paper clip removing device detects a position of the paper clip to heat the paper clip and deforms the paper clip into a shape of releasing a document bundle to attract and remove the paper clip, resulting that the paper clip is collected in the collecting box.

Abstract: A sheet transporting device including: a sheet feeding section that feeds plural sheets to a transporting path; three or more roller pairs that are arranged along the transporting path; a double feed detecting section that detects a length of a double feed portion when sheets are fed in an overlapped manner; a selecting section that selects two of the three or more roller pairs based on the length of the double feed portion; and a transport control section that can change a transporting speed of at least one of the selected roller pairs, wherein the selecting section selects two roller pairs that have a space between which the double feed portion can be positioned, and the transport control section controls the transporting speeds of the selected roller pairs such that the speeds differ from each other to separate the delaying sheet from the preceding sheet.

Abstract: A sheet transporting device including: a sheet feeding section that feeds sheets to a transporting path; a pair of upstream transporting rollers and a pair of downstream transporting rollers arranged with a predetermined space; a double feed detecting section that detects a length of a double feed portion; a determining section that determines whether the length of the double feed portion is shorter than the predetermined space or not; and a transport control section that controls the drives of the upstream transporting rollers and the downstream transporting rollers, wherein the transport control section controls speeds of the upstream transporting rollers and the downstream transporting rollers so as to separate the delaying sheet from the preceding sheet of the overlapped sheets, in a case where the determining section determines that the length of the double feed portion is shorter than the predetermined space.

Abstract: A sheet feeder includes: a feeding roller for feeding a sheet; a press member for pressing the sheet against the feeding roller; and a double feed detector for detecting double feed of the sheets when the sheets are fed in superimposition; wherein the feeding roller and the press member are opposed each other at a sheet holding portion for holding the sheet to be fed therebetween, and the double feed detector is placed to be able to detect double feed of the sheets in a region being adjacent to the sheet holding portion, an amplitude of the sheet being suppressed in the region.

Abstract: A main controlling portion controls each portion of a facsimile system, and when a communication controlling portion receives facsimile communication information from a sender indicated by predetermined sender information stored in a storing portion, causes a LAN controlling portion to notify a notify party indicated by notify party information associated with the received sender information of notification information only when determining that a predetermined notification condition is satisfied. It is possible to notify of the notification information only when the predetermined notification condition desired by a user is satisfied, and it is possible to increase convenience. Moreover, consequently, the facsimile system does not execute an operation process of notifying of the notification information when the predetermined condition is not satisfied, so that it is possible to prevent a wasteful operation process.
