Abstract:
An image reading apparatus in which the position of the boundary between an image of an original and a background image, as well as a skew and the size of the image of the original, can be accurately detected even with dust on a line image sensor or on an opposing member opposite to the line image sensor. An image formed on an original is read by a reading unit, and an opposing member is arranged at a position opposite to the reading unit. A plate glass distances the original from the opposing member. Shadow portions of the read image is detected from changes in a sub-scanning direction of pixel data of a read image generated based on output from the reading unit, and boundary coordinate data of the image of the original is obtained.
Abstract:
An image reading apparatus including a shading correction mechanism that can be formed by fewer component parts than conventional ones, and is increased in the degree of freedom of design, thereby enabling reduction of the size and weight thereof. A contact glass guides an original to an image reading position. A glass holding member holds the glass. A line image sensor reads an image on the original conveyed to the image reading location, through the contact glass. A reference member is disposed at a location different from the image reading location on the contact glass. A moving mechanism relatively moves the line image sensor and the reference member so that the line image sensor can alternatively read the original conveyed to the image reading location and the reference member. A drive section externally drives the moving mechanism to move the line image sensor and/or the reference member.
Abstract:
A thermal transfer sheet comprising: a substrate; a heat resistant slip layer provided on one side of the substrate; an undercoat layer and a dye layer provided in that order on the other side of the substrate, wherein the undercoat layer is formed by using colloidal inorganic pigment ultrafine particles and a copolymer resin of vinyl pyrrolidone and vinyl acetate as main components.
Abstract:
[PROBLEMS] It is an object to improve the workability in replacing a power storage stack.[SOLVING MEANS] A plug apparatus has a first holding portion 81 holding a stack connecting conductive wire 54, a second holding portion 82 separated from the first holding portion 81 and holding a stack connecting conductive wire 55, and a fixing portion 70 to which the first and second holding portions 81 and 82 are removably fixed, wherein the first and second holding portions 81 and 82 are fixed to the fixing portion 70 and the stack connecting conductive wires 54 and 55 are electrically connected to each other in a first state in which a plug grip 60 is mounted, and the first and second holding portions 81 and 82 are allowed to separate from the fixing portion 70 and the electrical connection between the stack connecting conductive wires 54 and 55 is broken in a second state in which the plug grip 60 is dismounted.
Abstract:
An information reading system comprising an information processing apparatus, a first information reading apparatus which is connected to the information processing apparatus and reads information on a sheet and a second information reading apparatus which is connectable to one of the information processing apparatus and the first information reading apparatus, and reads information on a sheet. The information processing apparatus comprises a control program including a first driver required to control the first information reading apparatus, and a second driver required to control the second information reading apparatus. Control information from the information processing apparatus to the second information reading apparatus is transmitted via the first driver and the second driver.
