Abstract: A printer includes a medium feeding device that is one of different types of medium feeding devices including a first medium feeding device that feeds an elongate medium from a first print medium including the medium, and a second medium feeding device that feeds the medium from a second print medium including the medium and a plurality of wireless communication elements provided at intervals in the longitudinal direction of the medium, and a printing device including a printing portion that performs printing on the medium fed from one of the medium feeding devices. The printing device includes a connector portion that is selectively connectable to the common connection portion of each of the different types of medium feeding devices. The second medium feeding device includes a wireless communication portion that communicates with the wireless communication elements, and a terminal portion that connects the wireless communication portion to the printing device.

Abstract: A roll support device includes: a shaft portion that supports a center hole of a rolled medium in which a medium is wound; a first guide member with which one end surface of the rolled medium in an axial direction of the shaft portion is in contact; a second guide member that is provided on the shaft portion and regulates, in the axial direction, an inner peripheral side of another end surface of the rolled medium in the axial direction; and a third guide member that regulates, in the axial direction, an outer peripheral side of the other end surface of the rolled medium supported by the shaft portion.

Abstract: A roll supporting device includes: a pair of supporting rollers which support an outer circumferential surface of a rolled medium, and which are provided so as to rotate together with the rolled medium; a side wall which has a reference surface coming into contact with one end surface of the rolled medium in an axial direction along a central axis of the rolled medium; and a pair of restricting members which press another end surface of the rolled medium toward the reference surface. The pair of supporting rollers are disposed on both sides of the central axis of the rolled medium when viewed in the axial direction of the rolled medium. The pair of restricting members are disposed outside a space between the pair of supporting rollers in a circumferential direction of the rolled medium, and are respectively adjacent to the supporting rollers, and are provided so as to be movable independently from each other.

Abstract: A page-turning apparatus comprises a first roller and a second roller, and also a guide located between the first roller and second roller. The guide is supported with a arm. A bankbook is carried by the first roller and the second roller, and the second roller is locked while the first roller is rotated. With the rotation of the first roller, a page of the bankbook is warped and rejected. The guide swings along the warped and rejected page. By carrying the bankbook with the page as it is, the page can be turned over.

Abstract: Disclosed is a page turning apparatus for turning over a page of a medium. This page turning apparatus comprises a drive roller for turning over a page of the medium and carries the medium on a carrier path, a pressing roller, a carrier motor for driving the drive roller, a movable panel for bending the medium, a clamping member for clamping the medium, a driving member for driving the pressing roller, the movable panel and the clamping member, and a control circuit for controlling the driving member and the carrier motor. The control circuit has a page turning mode for retreating the pressing roller, protruding the movable panel and the clamping member, and driving the drive roller, and a carrier mode for pushing the pressing roller against the drive roller, retreating the movable panel and the clamping member, and carrying the medium by the drive roller. The single motor thereby works to turn over the page of the medium and to carry the medium.

Abstract: A process of producing plastic-molded printed circuit boards by injection-molding a heat resistant plastic to form a plastic molding having many perforations and forming a conductive layer on the molding, which comprises molding the heat resistant plastic using a mold for injection-molding obtained by preparing a die set for injection-molding composed of a fixed side metal platen having at least an inlet for molten resin and forming a space for installing mold part(s), a stripper metal platen having, if necessary, an inlet for molten resin connected to the fixed side metal platen and forming a space for installing mold part(s), and a movable side metal platen forming a space for installing mold part(s); and assembling a pair of molds composed of a mold I having a concaved portion for cavity and a mold II having perforations for passing hard pins for forming holes and, if desired, a concaved portion for cavity, said molds being formed by a cured resin composition or a composite of a metal and a cured resin com
