A reading device includes a carriage configured to move in a sub-scanning direction with reference to an object placed on a contact glass, an optical sensor attached to the carriage, the optical sensor being configured to scan the object placed on the contact glass to obtain an image of the object, and a reference scale used as a reference when a dimension of the object is computed based on the image obtained by the optical sensor. In the reading device, the reference scale extends in a main scanning direction and a sub-scanning direction with reference to the object, and is disposed outside a range of image acquisition in which the optical sensor scans the object to obtain the image of the object as the carriage moves and inside a maximum movement range in which the carriage is movable and the optical sensor obtains the image of the object.

Provided is a technique for allowing a user to easily check the status of an image scanning apparatus. An image scanning apparatus is configured to transmit original document image data by storing, sequentially in a buffer, line data obtained by line-by-line scanning of an original document and transmitting the stored line data to a host computer sequentially line by line, and includes a control unit configured to perform control to transmit original document image data including notification image data to the host computer in a case where it is detected that the apparatus status of the image scanning apparatus is not normal during processing executed in response to a scan command received from the host computer, the notification image data being a notification of an error occurrence.

A flat panel has a plurality of pixel areas each having a light emitting area, a light transmitting area, and a light sensing area in the light emitting area. The flat panel includes a first support board; a sensing array on the first support board and having a light sensing element corresponding to the light sensing area of each of the pixel areas; a micro lens between the first support board and the light sensing element; a first light shielding wall between the first support board and the light sensing element to correspond to an edge of the light sensing area of each of pixel areas; a light emitting array on the sensing array and having a light emitting element corresponding to the light emitting area of each of the pixel areas; and a second support board on the light emitting array facing the first support board.

A reading apparatus, having a platen glass, a document cover, a conveyer, a reading sensor, a document supporting member, a pressing plate, and a linkage assembly, is provided. The document cover is movable between an open position and a closed position. The document supporting member is movable between a first position, where the document supporting member faces a reading surface of the reading sensor, and a second position, where the document supporting member is separated from the reading surface. The pressing plate is movable between a third position, where the pressing plate is attached to a lower side of the document cover, and a fourth position, where the pressing plate is removed from the lower side. The linkage assembly moves the document supporting member from the first position to the second position in conjunction with the pressing member moving from the third position to the fourth position.

A reading apparatus, having a document tray, an ejection tray, a conveyer path connecting the document tray and the ejection tray and having a curved section, a conveyer to convey an original document in a conveying orientation, a first reading sensor, and a second reading sensor, is provided. The first reading sensor is located upstream in the conveying orientation from the curved section in the conveyer path. The first reading sensor optically reads a first side of the original document from below. The second reading sensor is located upstream in the conveying orientation from the first reading sensor in the conveyer path. The second reading sensor optically reads a second side of the original document from below. The first side and the second side are sides of the original document that face upward and downward, respectively, in the state where an original document is placed on the document tray.

An original reading apparatus includes: a reading unit configured to read an original placed on a platen while moving in a predetermined direction in a housing; a sensor provided in the housing and configured to detect presence of the original in a predetermined position on the platen to identify a size of the original; a holding member movable in the housing and configured to hold the sensor and a cable extending from the sensor; and a cover configured to cover a predetermined space on a rear side of the platen mounted to the housing. A grip portion used by an operator to move the holding member is provided at one end of the holding member extending to the predetermined space through an opening portion in a wall on a rear side of the housing. When the cover is removed, the operator is allowed to grip the grip portion.
