Abstract: An image forming apparatus as a sheet conveying apparatus comprises a paper feeding roller, an upstream side sensor, and an ultrasonic wave sensor. The paper feeding roller provides a plurality of sheets placed on a document tray in series to a conveying path. The upstream side sensor detects presence or absence of a sheet being conveyed along the conveying path, at a location of a downstream side of the paper feeding roller along the conveying path. The ultrasonic wave sensor detects presence or absence of occurrence of multiple feed, based on intensity of ultrasonic waves received at a location of a downstream side of the upstream side sensor along the conveying path.

Abstract: Provided are an image forming system and a method for detecting glossiness capable of accurately detecting glossiness in various media having different conditions.
The image forming system includes a sensor unit including a light source that irradiates a medium being conveyed with light and a gloss sensor that receives light emitted from the light source and specularly reflected on the medium and detects a diffusion distribution of light in the medium, and a detection condition setting unit that identifies a type of the medium being conveyed and sets a light amount of the light source and/or exposure time of the gloss sensor at the time of glossiness detection in accordance with the type of the medium. The image forming system further includes a glossiness detector that detects glossiness of the medium from a diffusion distribution of light detected by the gloss sensor under the detection condition set by the detection condition setting unit.-

Abstract: A paper sheet sensing device includes: a sheet thickness sensor that includes a reference member and a displacement sensor, and senses a sheet thickness of a conveyed recording medium by bringing the reference member into contact with the recording medium and sensing a position of a height of the reference member with the displacement sensor, the position of the height having changed with the recording medium; a first attacher to which the sheet thickness sensor is attached; a conveyor that nips and conveys the recording medium, and is disposed adjacent to the sheet thickness sensor at a predetermined distance equal to or shorter than a length of the recording medium being conveyed, in a conveyance direction of the recording medium; and a displacement preventer that prevents a change in an output of the displacement sensor due to a shift of a relative position of the height of the reference member.

IPC: G03G15/00
Abstract: A sheet conveying apparatus has a reference roller, a detection roller, and a detection sensor. The detection roller can move, and makes contact with the reference roller, facing the reference roller. The detection sensor outputs a signal corresponding to the displacement of the detection roller. The sheet is conveyed to a nip portion of the pair of rollers. At this time, the timing when an edge portion of the sheet being conveyed passes through the nip portion is detected. In response to the timing detected, the thickness of the sheet is detected, based on the signal output from the detection sensor.

Abstract: An image forming apparatus receives setting of an object to be adjusted, on an adjustment object selection screen when selecting an adjustment mode. After the object to be adjusted is set, camera(s) photograph(s) the object to be adjusted so that the image forming apparatus obtains photographed data of current object to be adjusted. Next, the apparatus searches photographed data of the object to be adjusted in the ideal state thereof from the database. Name of the object to be adjusted and related information in the photographed data agree with those of the photographed data of current object to be adjusted. The higher ranked related information is preferentially searched and it is determined whether or not pieces of the higher ranked related information thus preferentially searched agree with each other.
Abstract translation: 图像形成装置在选择调整模式时，在调整对象选择画面上接收待调整对象的设定。 在设置要调整的对象之后，照相机拍摄要调节的对象，使得图像形成装置获得要调整的当前对象的拍摄数据。 接下来，该装置从数据库中搜索要在其理想状态下调整的对象的拍摄数据。 要被调整的对象的名称和拍摄数据中的相关信息与被调整的当前对象的拍摄数据的名称一致。 优先搜索较高等级的相关信息，并且确定这样优先搜索的较高等级的相关信息的片段是否彼此一致。
