A printing apparatus capable of adding number information differing from copy set to copy set, to a printing target image includes a judging unit configured to judge whether to add user information indicating a current user to a printing target image, and a determination unit configured to determine a position to which the number information is to be added, based on a result of the judgment performed by the judging unit.

A printing apparatus capable of adding information to a printing target image includes an addition unit configured to add the information, a setting unit configured to set an area to which the information is added based on a user operation, a specification unit configured to specify a length of a sheet used for printing in a sheet conveyance direction, and a control unit configured to control, in a case where the length of the sheet in the sheet conveyance direction is not specified, the addition unit to add the information into a leading end side area in the sheet conveyance direction even if a trailing end side area is set by the setting unit as the area to which the information is added.

An image reading device includes a contact glass, a document transport device, a first reading module, a second reading module, a opposite roller, and roller holders. The opposite roller transports a document while keeping it in close contact with an image reading surface of the second reading module arranged inside the document transport device. The roller holders rotatably support the opposite roller, and on their faces facing the second reading module, a pair of patterns for detection is provided to detect the inclination of the opposite roller. The patterns for detection are each formed to be increasingly wide toward a first end side in the axial direction upstream from an intersection in a central part thereof in the document transport direction, and increasingly wide toward a second end side opposite from the first end side downward from the intersection in the document transport direction.

An inspection apparatus which inspects an image determines a type of a printing error based on characteristics of a place where the printing error has occurred, and controls a printing apparatus according to the determined type of printing error.

Disclosed is a preprinting system of secured information connected to a game host device. The preprinting system includes a controller, a printer, a plurality of printer detectors, a housing, a plurality of housing detectors. The controller is configured to communicate with the game host device, and to receive a game information signal and a status checking request signal. The printer is electronically connected to the controller, which is configured to print a game draw of the game program on printable medium, and the printed printable medium is partially revealed to the player while the game result draw thereon is unknown to the player. By preprint game draw of the game program, the possibility of adulteration from the game system is eliminated, the preprinting system also provides reliability, and the verification mechanism provides information security of digital chance games to the players. An preprinting method of secured information is also disclosed.

An image forming apparatus comprises a sensor, a base, a clamping section and a limiting section. The sensor includes a hook having a claw section. The sensor is held on the base. The clamping section and the limiting section are arranged on the base. The claw section is clamped with the clamping section. The limiting section is elastically deformable when the sensor is mounted on the base. When the claw section is clamped with the clamping section, the limiting section faces the hook from the opposite side of the clamping section so as to limit the position of the hook.

In accordance with an embodiment, an image processing apparatus comprises a conveyance section, a first image reading section and a detection section. The conveyance section conveys a sheet in a first scanning direction. The first image reading section reads an image of the sheet conveyed by the conveyance section per line of a second scanning direction orthogonal to the first scanning direction. The detection section, based on an image signal read by the first image reading section, detects a front end portion and a rear end portion of the sheet in the first scanning direction.

An image reading device includes an image reading portion, a restriction portion, a limitation processing portion, and an output processing portion. The image reading portion reads an image of a document sheet. The restriction portion restricts a position of the document sheet in a width direction. The limitation processing portion limits an image reading range in the width direction to a document sheet width corresponding to a position of the restriction portion. The output processing portion reads, when the image reading range is limited to a specific document sheet width, an image of the document sheet, detects a contact end portion that comes into contact with the restriction portion in the document sheet included in a read image obtained by the reading, and clips and outputs, from the read image, a region determined based on the contact end portion and a determination result on a size of the document sheet.

Example implementations relate to print media rollers. For example, implementations can include a device that includes a first roller to receive print media, a first sensor to determine when a leading edge of the print media is at a first location, a second roller to be activated based on a type of the print media and when the leading edge of the print media interacts with the first sensor, a second sensor to determine when the leading edge of the print media is at a second location, wherein the first roller is deactivated based on when the leading edge of the print media interacts with the second sensor.
