An image reading apparatus includes a sensor, a light source, and an image-capture controller. The sensor has a sensitivity area that is in a predetermined wavelength band, and acquires an image signal in accordance with light from sheet. The light source has a first light emitting unit that emits first light having a wavelength within the sensitivity area of the sensor, and a second light emitting unit that emits second light that has a wavelength which is outside of the sensitivity area of the sensor and that excites a fluorophore applied on the sheet. The image-capture controller irradiates the sheet with the first light and the second light to acquire a first image signal using the sensor, and irradiates, after acquiring the first image signal, the sheet with only the second light to acquire a second image signal using the sensor.

A sheet processing apparatus, comprising a thickness detecting device, the thickness detecting device including:

Sheet processing apparatus and method of detecting thickness of sheet

According to one embodiment, a document handling apparatus includes an image detection unit including a plurality of light sources to irradiate a surface of a paper sheet as an inspection target with light from two different directions, and a light receiving unit configured to receive reflected light from the surface of the paper sheet, and configured to detect an image on the surface of the paper sheet, and a detected information processing unit configured process detected information from the image detection unit and determine a defacement degree of the paper sheet. The detected information processing unit is configured to detect gray contamination of the paper sheet from an image detected by simultaneously turning on the plurality of light sources and to detect wrinkles or folds of the paper sheet from an image detected by turning on one of the plurality of light sources.

Document handling apparatus

A sheet processing machine transmits information indicating a degree of contamination or damage for each sheet detected by a discrimination unit to a teller PC as a discrimination result. The teller PC saves the discrimination result received from the sheet processing machine in a data storage unit. A CPU of the teller PC decides reference levels that can attain good bill ratio designated by the user for respective items required to discriminate good/bad states of a sheet based on the previous discrimination results saved in the data storage unit. The CPU of the teller PC sets the reference levels that can attain the good bill ratio designated by the user in the discrimination unit of the sheet processing machine. The discrimination unit set with such reference levels discriminates good/bad states of sheets based on the reference levels set by the teller PC.

Image identifying apparatus

An automatic mail processing apparatus comprises a physical quantity detection section for detecting physical quantities of mail with a stamp, such as the weight and dimensions of the mail, a postage determining section for determining the valid postage for the mail with reference to a table in which valid charges are previously stored on the basis of the information items indicating physical quantities, and a stamp detection section for detecting the amount paid on the basis of the information on the stamp contained in the image of the mail, and a processing section for verifying the determined postage with the amount paid to detect a surplus or deficit of the amount paid, and to identify the kind of the mail, classify the mail, and compile statistics data on the mail.

Processing apparatus for mail with stamps

An apparatus is capable of reading a character or graphics image on a document at a plurality of reading linear densities. An illuminating device for illuminating the document, a focusing device for focusing the light beam reflected by the document, and a CCD reading sensor for converting the focused light beam into an electric image signal, are integrally assembled together to constitute a carriage device. This carriage device is shifted in a desirable shifting which is determined on the basis of the reading sensitivity of the CCD reading sensor and which corresponds to the linear reading density. The rotation speed of a driving device used for driving the carriage device is reduced to a desirable value by means of a transmission, the conversion ratio of which is determined on the basis of the least common multiple (LCM) of a plurality of reading linear densities. The driving pulses which should be supplied to the driving device can be easily calculated by use of the product of the 'reference pulse ' .phi.p and the 'multiplier unit' Un, which are also determined on the basis of the above least common multiple.

Apparatus for reading character or graphics image on document

An image reading apparatus for reading image formed on a document. The apparatus includes a scanner for scanning the image and forming image data, a driver for driving the scanner, a data processor for processing the image data and outputting information generated from the image data, a memory storing the output information from the data processor and a controller for setting a large thinning rate to be used by the data processor at a rough reading operation.

Image reading apparatus

A line sensor apparatus is adapted to read a character or pattern image on a document. In this apparatus, an illumination device for illuminating the document, a optical lens for focusing the light beam reflected by the document, a CCD line reading sensor for photoelectrically converting the light beam focused by the optical lens into an electric signal, and a holding member for holding the CCD line sensor and the optical lens are assembled as one body in such a manner as to constitute a carriage device. A uniformly radiated heat-radiating plate is in contact with the entire botttom surface of a support for the CCD line sensor, so that the heat generated by the CCD line sensor is radiated from the heat-radiating plate. Further, the CCD line sensor is kept in tight contact with the holding member, so that the heat generated by the CCD line sensor is also radiated from the holding member.
