The guide member assembly includes a guide member, a positioned portion, and a support member. The support member supports the guide member and has a side wall that extends in such a direction as to intersect a line drawn in the width direction and that has a hole through which a support shaft is inserted with some play being present. The guide member assembly is supported by the door with some play being present between the guide member assembly and a base plate and is urged by an urging member. The hole is a long hole having a major axis extending in an opening direction of the door away from a center line of rotation of the door.

An image forming apparatus includes a transfer member onto a front side of which an image is transferred, a rotary member around which the transfer member is wrapped, a guide member provided at an end portion of an axial direction of the rotary member, a regulating member, a first reference mark, a second reference mark, a first detector, a second detector, and a controller. The regulating member is located on a reverse side of the transfer member, and restricts skew of the transfer member by contacting the guide member. The first and second reference marks are on edge sides of the transfer member in the axial direction of the rotary member. The first and second detectors detect the first and second reference marks, respectively. The controller controls alignment of the image on the transfer member in accordance with a detection result of the first and second detectors.

Disclosed is a microanalysis chip adhesive sheet with an adhesive surface, which can be inexpensively but easily bonded to a substrate at a relatively low temperature, with which fabrication of analysis chips is simplified, and which has the capability of fixing a selective bonding substance to the sheet surface. The microanalysis chip is characterized in that a microanalysis chip adhesive sheet, which comprises a plastic sheet provided with an adhesive layer formed from an adhesive that contains a polymer in which monomer structural units that contain carboxyl radicals or acid anhydride radicals constitute 5-25% by weight of the [total] monomer structural units in the polymer, and a substrate, which has protrusions and recesses on the surface thereof, are bonded together so that the surface of the substrate having the projections and concavities and the adhesive layer of the aforementioned microanalysis chip adhesive sheet are on the inside. Gaps at the concave parts of the substrate between the substrate and the adhesive layer of the aforementioned microanalysis chip adhesive sheet form a flow path, a part of which is the aforementioned adhesive layer, and a selective bonding substance is fixed to the adhesive layer surface.

A method of printing a test pattern to form dots on a printing medium. A print head moves relative to the recording medium and the test pattern is used to inspect the printing element. The method has a line printing step for printing a dot line having predetermined length while moving the print head relative to the recording medium in a first direction of the recording medium; and a step of moving the print head relative to the recording medium in a second direction perpendicular to the first direction such that the printing element prints a dot line close to a dot line previously printed in the second direction, wherein the line printing step and the moving step are repeated alternately, and each printing element individually prints a plane image which is a assemblage of a plurality of the dot lines as a component part of the test pattern.

At a predetermined position during the lateral movement of a carriage 10, a gap switching mechanism 30 for switching a gap between a recording head 15 and a recording medium is provided. The recording head 15 is mounted facing downward on the carriage 10. A part close to one side on a lower end of the carriage is slidably and pivotably supported by a guide shaft 11 of a round shaft shape. A switching block member 13 provided with several abutment portions 52 and 53 with different heights, which are positioned so as to be opposed to a slide portion 12a at an upper end of a frame 12 extending in a vertical direction along a back of the carriage. The A switching block member 13 is pivotably supported by the carriage. A first pushing portion 56 is located at a left end of the frame so as to abut against the switching block member 13. A pivotal posture of the first pushing portion is changed due to the abutment to bring the abutment portion 53 into a slide contact relationship with the frame 12, so that a small gap is provided. A second pushing portion 57 is located at a right end of the frame so as to abut against the switching block member 13, a pivotal posture of the first pushing portion is changed according to the abutment to bring the abutment portion 52 into a slide contact relationship with the frame 12, so that a large gap is provided.

A printing device includes a sheet feeding mechanism that feeds the recording sheet by a predetermined amount at a time, a carriage that is movable, substantially at a constant speed, in a direction substantially perpendicular to a sheet feeding direction, and a print head mounted on the carriage. The print head is capable of simultaneously forming a plurality of print lines when the carriage moves. The print head is controlled to print a first print pattern that is formed by part of the plurality of print lines on an upstream side. The recording sheet is fed by the predetermined amount after the first pattern is formed. Thereafter, a second print pattern that is formed by part of the plurality of print lines on a downstream side after the recording sheet is fed. At least a part of the first print pattern overlaps a part of the second print pattern.
