    摘要: A process unit includes a drum frame supporting a photoconductor drum and a development frame supporting a development roller. The development cartridge is swingably supported by the drum frame at a coupling joint provided at a first side of the development frame and a support portion provided at a second side of the development frame. A center of rotation of the development roller is located in a position shifted from a line segment connecting a center of rotation of the coupling joint and a center of rotation of the photoconductor drum to an upstream side with respect to a direction of rotation of the coupling joint as viewed in an axial direction of the development roller, such that the development roller is pressed against the photoconductor drum by the action of the rotatory force received by the coupling joint.

    摘要: A sheet roll comprises two glass films and a coupling portion, wherein end portions of the glass films are coupled together via the coupling portion and the coupled glass films are rolled into a roll shape. The coupling portion is a sheet-like coupling member formed of a resin film and placed on the end portions of the two glass films in a rolling direction so as to span therebetween. The sheet-like coupling member includes wide joint portions joined respectively to the end portions of the two glass films, and a necked portion which is narrower than the wide joint portions and is formed at a middle portion of the sheet-like coupling member in the rolling direction.

    摘要: A cleaving apparatus holds at least one surface (effective surface) of a band-like glass film in a non-contact state to suppress a situation that wavy portions reach a region in which the band-like glass film is to be cleaved. The cleaving apparatus cleaves the band-like glass film, which is being conveyed in a longitudinal direction thereof, along a conveyance direction thereof using a thermal stress generated through localized heating and cooling of a heated region. The localized heating and the cooling is performed on a preset cleaving line extending along the conveyance direction of the band-like glass film. The cleaving apparatus includes an air knife for supplying air to a front surface of the band-like glass film to retain the film on a conveyor at a position on an upstream side of a cleaving region in the conveyance direction.
