A sheet fastener includes a first fastening member having a long size and a second fastening member having a long size. The first fastening member includes: a first main body portion including a secured surface; a first engagement portion; a plurality of first slit portions formed along an intersecting direction; and a first continuous portion continuous along a longitudinal direction. The second fastening member includes: a second main body portion including a secured surface; a second engagement portion; a plurality of second slit portions formed along an intersecting direction; and a second continuous portion continuous along a longitudinal direction. By using the sheet fastener according to the present invention, the sheet edge portion, which is curved, of the second sheet member can be easily and smoothly fastened with the sheet edge portion, which is curved, of the first sheet member.

There is provided a cover-material fixing tool. A cover-material fixing end member is configured to be attached on a cover-material. A clip is configured to be attached on a cover-material fixing end member. The cover-material fixing end member includes a tape member, a clip locking member, and a plurality of stoppers. The clip includes a locking portion for holding the clip locking member to allow the clip locking member to move in a longitudinal direction, and a locking protrusion protruding toward the clip locking member and configured to abut against the stoppers. The clip is movable between the adjacent stoppers to allow position adjustment thereof.

Skin-material fixing tool

A cover-material fastening clip includes a locking portion having a guide piece and a hook which includes an extension portion and a distal end portion. The guide piece extends includes a bent portion bent and extended toward the distal end portion. An insertion opening having a predetermined gap and allowing a wire to be inserted therethrough is positioned between the bent portion and the distal end portion. A distal end portion of the guide piece extending from the bent portion is an elastic piece portion being elastically deformed to be spaced from the distal end portion and to widen the insertion opening. In a part of the locking portion, which is located within a range, in which the elastic piece portion can be elastically deformed and thus moved, an escape space is provided to allow a distal end of the elastic piece portion to be positioned therein.

Cover material fastening clip

A slide fastener includes a right and left pair of first fastener stringers and second fastener stringer, and a slider. The first fastener stringer and the second fastener stringer each include a fastener tape, a fastener element array, and a restricting unit restricting displacement of right and left cover materials away from each other. The restricting unit is configured to form a space that receives a side periphery of each of the cover materials between the restricting unit and the fastener tape.

An image forming apparatus includes an optical writing device. The optical writing device includes an optical writing unit that emits laser light beams toward image carriers, an outer case that accommodates the optical writing unit, and air supplying devices that supply air into the outer case. The outer case includes openings through which the laser light beams pass. Another image forming apparatus includes an optical writing device that emits laser light beams toward image carriers to form latent images thereon, partition members that are interposed between the image carriers and the optical writing device and that have openings elongating along a scanning direction of the optical writing device, and shutter mechanisms including shutter members to open and close the openings. The laser light beams are emitted from the optical writing device toward the image carriers through the openings.

A housing in which a heat source for heating a member to be heated is disposable includes a first end and a second end in a longitudinal direction. Each of the first end and the second end is linked to a duct. A blowing unit is provided at the first end of the housing and causes an airflow in a space formed in a state in which the heat source is disposed in the housing. The duct linked to the second end of the housing is formed to extend from the second end. A length of the duct linked to the second end of the housing is longer than a hydraulic diameter by a predetermined number of times or more.

Heat exhausting structure and image forming apparatus

An image forming apparatus includes a first frame plate and a second frame plate, which has an extended portion horizontally extending by a predetermined length compared with the first frame plate. The first and second frame plates are oppositely disposed spaced apart by a predetermined width from each other. An open and close unit, which includes a recording medium conveying system, is disposed within an area of the extended portion between the first and second frame plates and is configured to freely open and close with respect to the image forming apparatus. And a drive controlling mechanism is configured to control the recording medium conveying system. The extended portion supports at least a portion of the drive controlling mechanism so as to be separately mounted on a side of the image forming apparatus.
