Provided are a printing jig for an inkjet-type printer and a method for manufacturing printed objects therewith, which jig can be easily produced in accordance with the shape and size of an object to be printed and allows the object to be accurately positioned relative to the printer. The printing jig supports an object to be printed, and is placed in an inkjet-type printer when the object is being printed. The printing jig includes a mounting surface on which the object is to be placed, and a positioning part for positioning the object. The positioning part includes a protrusion preformed on the mounting surface so as to be brought into contact with at least part of the object placed on the mounting surface. The protrusion is made of deposited and cured ink used by the inkjet-type printer.

A band comprised of a plurality of link members connected to each other to be able to pivot by pivot shafts, in the band, at least one of the plurality of link members has a sheet member and a wrapped member around which the sheet member is wrapped, the wrapped member has a side part facing an adjoining link member, and at least one end part of the sheet member is arranged between a top end part and bottom end part of the side part in the thickness direction.

Band

Substantially cylindrical head tube body, center tube body and tip tube body threadedly engage each other to thereby construct a tool main body of a tool for wristwatch. The through hole of the center tube body is provided with a partition part having a small-diameter hole and slant face. A hammering member and compression spring are slidably accommodated in the through hole. A trigger shaft includes a small-diameter part which can be inserted in a center hole of the hammering member, and a large-diameter part continuing therefrom through the slant face, which can pass through the small-diameter hole. A deformed coil spring has the large-diameter part of the trigger shaft fitted therein in wound form, and energizes the trigger shaft toward sliding shaft while slanting the trigger shaft so as to cause the small-diameter part to shift toward the inside wall of the tool main body. The sliding shaft at its rear end includes large-diameter head part and at its front end includes an engagement part to which a wristwatch tool component can be replaceably fixed. The engagement part interlocks a small-diameter hole of the tip tube body with a play, and the front end of the engagement part protrudes from the tip tube body.

Tool for wristwatch

A coupling structure of a watch band in which a coupling member such as a coupling pin or a hair pin does not sup from a coupling hole even if a user practices strenuous sports or a rotation and a twist are always applied to the coupling portion due to use for years, and a method of manufacturing a piece member for the band coupling structure. In a coupling structure of a band comprising a plurality of piece members, a projection protruded in a central direction of a coupling hole from an internal wall of the coupling hole is formed on an outer end of the coupling hole in the piece member positioned on an outside in a transverse direction, and a coupling member is inserted in the coupling hole provided in the transverse direction of the piece member and is engaged with the projection, thereby coupling the piece members to each other.

A link is made by bending a metal plate, and comprises a plurality of annular portions (,) and connecting portions (,) between the annular portions. An annular connecting link (,) has a gap through which the connecting portion passes and engaged with the connecting portion. A connecting member (,) having a base (,), a connecting arm (,), and an end portion is provided to be inserted between the link and the connecting link so as to connect the connecting link to the link with the connecting arm. A stopping means (,) is provided for holding and stopping the connecting member within the link. An opening is provided for disclosing an outer surface of the end portion of the connecting member from one of the annular portions at an end thereof, so as to allow a tool (,) to push the connecting member.
