A sheet feed roller portion () feeds a plurality of bound sheets (S) to a conveying path (). The ultrasonic sensor () detects a voltage value that changes according to a thickness of the sheet (S) at a measurement position (P) on the conveying path (). A determination processing portion () determines whether or not a voltage difference between voltage values of the sheet (S) detected by the ultrasonic sensor () is equal to or greater than a preset threshold value. A light amount adjustment processing portion () adjusts a light amount of light emitted from a CIS sensor () and irradiated onto the sheet (S) when the determination processing portion () determines that the voltage difference is equal to or greater than the threshold value.

Image reading apparatus, image forming apparatus, and image reading method

A first image reading portion is disposed in a body portion. A conveying device is disposed in a cover portion. A second image reading portion is disposed in the cover portion. An inclination derivation portion derives two inclination angles of a document sheet respectively corresponding to the first image reading portion and the second image reading portion by performing image processing on two read images obtained by the first image reading portion and the second image reading portion. An information output portion outputs inclination correction information based on the difference between the two inclination angles through an information output device.

Image reading apparatus, image processing method

An image processing apparatus includes a fluctuation generating portion, and a connection identifying portion. The fluctuation generating portion fluctuates an output power of a power supply portion that supplies power to a load. The connection identifying portion identifies a connection relationship between the power supply portion and the load based on a correlative relationship between a fluctuation of the output power and a fluctuation of the power supplied to the load.

Image processing apparatus whose main body is electrically connected to expansion device, image processing method and non-transitory recording medium

An electronic device includes an element, a first member, and a second member. An electric current flows in the element. The element is mounted in the first member or the first member is arranged to face the element. In addition, the first member is made of a first resin. The second member is provided adjacent to the first member. In addition, the second member is made of a second resin. In addition, one of the first resin and the second resin has lower non-flammability than the other.

Electronic device including element in which electric current flows, and image forming device including the electronic device

A control section allows a screen of a display section to display a plurality of numeric keys, detects a touch gesture on the individual numeric key through a touch panel to allow an input of a numeric number corresponding to the numeric key subjected to the touch gesture, and detects an action on each of hard keys to accept an instruction to perform a function corresponding to the hard key subjected to the action. When a predetermined action is performed on one or more individuals of the hard keys, the control section assigns numeric numbers to the respective hard keys and detects an action on the individual hard key to allow an input of the numeric number corresponding to the hard key subjected to the action.

Input device

An original document size estimating device includes a first optical sensor and a second optical sensor operable to detect an original document placed on a specified position. The first optical sensor is positioned before the second optical sensor with respect to a forward direction. The first and second optical sensors are moved in both the forward direction and a backward direction opposite to the forward direction by a driver. The driver is controlled in such a manner as to forcibly move the first and second optical sensors in the forward direction further a predetermined additional distance when the first optical sensor generates absence signal and the second optical sensor generates presence signal, and return them after both generating absence signal to measure a length of the original document for size estimation.

Device for estimating a size of an original document

An image forming apparatus comprises a document feeder for feeding a plurality of documents one by one, a copy paper feeder for feeding a copy paper sheet having a front surface and a rear surface onto which document images are transferable, an image transferring assembly for transferring an image of the fed document onto a copy paper sheet, an operable unit for discharging the copy paper sheet or temporarily retaining the copy paper sheet therein to refeed the sheet to the image transferring assembly when a next document is fed, a mode setting key for selectively setting in advance either of a first mode in which the copy paper sheet onto which the last document image is transferred is forcibly discharged or a second mode in which the copy paper sheet onto which the last document image is transferred is temporarily retained in the operable unit, and a CPU. The CPU determines that an image of a last document of the plurality of documents has been transferred onto one of the two surfaces of the copy paper sheet and determines in accordance with the result of the above determination that the last document image is transferred onto a front surface of the copy paper sheet. Further, based on the determination as to whether the last document image is transferred onto the front surface of the copy paper sheet and the mode set by the mode setting key, the CPU controls the operable unit so as to execute one of the operations of discharging the copy paper sheet onto the rear surface of which the image of the document is transferred, discharging the copy paper onto the front surface of which the last document image is transferred in the case where the first mode is selected, and retaining therein the copy paper onto the front surface of which the last document image is transferred in the case where the second mode is selected.
