A cleaner unit to clean an inkjet head, ejecting ink onto a recording medium, and an ink conveyer tube, conveying the ink to the inkjet head, of an inkjet printer in cleaning liquid, is provided. The cleaner unit includes an air-liquid two-phased cleaner conveyer tube, which conveys air-liquid two-phased cleaner, and a cleaner spout, which is connected to an upstream-side end of the ink conveyer tube and to a downstream-side end of the air-liquid two-phased cleaner conveyer tube with respect to a fluid flow, and through which the air-liquid two-phased cleaner is supplied to the ink conveyer tube.

Obtained are an imaging optical system having a simple structure in which imaging position deviation due to deformation caused by a weight of an off-axial optical element is reduced and an image reading apparatus using the same. According to an imaging optical system for image reading, image information on an original surface is imaged on a sensor, and is read by the sensor. The imaging optical system includes reflection-type off-axial optical elements, each of which has an outer shape whose lengths in directions orthogonal to each other are different from each other and whose thickness is smaller than a length of the outer shape in a short-direction thereof and is made of a resin material. The plurality of off-axial optical elements are disposed such that mirror surfaces thereof are opposed to each other and constructed to satisfy a conditional expression.

An object is to provide an imaging optical system having a very simple structure that can read image while maintaining excellent image quality without suffering from significant asymmetrical aberrations. An imaging optical system for image reading is adapted to form an image of image information on a surface of an original onto a line sensor while changing a relative position of the original surface and the line sensor to allow the line sensor to read the image information. The imaging optical system includes two off-axial reflecting surfaces, and the two off-axial surfaces are a plus deflecting surface and a minus deflecting surface, or a minus deflecting surface and a plus deflecting surface disposed in the mentioned order from the original surface side, where an off-axial reflecting surface that deflects a reference axis beam clockwise is defined as a minus deflecting surfaces and an off axial reflecting surface that deflects the reference axis beam anticlockwise is defined as a plus deflecting surface.

In an image read apparatus which reads an image from a recording medium, such as a film, and outputs image data, and shading correction data is set. Time elapsed since the shading correction data is set is counted. Before performing main scanning, whether or not the elapsed time is longer than a predetermined period is determined, and if it is, the shading correction data is updated. The read image data is processed with shading correction using the shading correction data which is updated as time elapses.

Test environmental programs are prepared using the following steps: Upon application of H/W specification information containing information on the system architecture, a guidance is displayed based on the H/W specification information and the user is caused to input subsystem definition information. The H/W specification information and the subsystem definition table are related to each other to prepare the specification description of system architecture, which is used together with the simulator in a simulator library to generate test environment programs according to a testee designation. In the application-specific hardware simulator, a hardware simulation model simulating the I/O device behavior is prepared as follows: An internal connection analysis table and a definition table defining various system architectures are prepared from the hardware description information describing the I/O device hardware specification in the specification description language. An external I/O interface definition table is thus prepared from an I/O device hardware specification, an interface routine for data conversion between the I/O device and the application-specific hardware simulator and information from the user for designating the correspondence between the I/O device and the interface routine. These various tables are used to generate a source program for the hardware simulation model.
