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.

A cord storage device has a base member with two sides, and a plug receptacle extending from one side. The plug receptacle anchors a plug end of an electronic device cord and forms a core about which the cord can be wound. A flexible retaining wall is coupled to the base member and moves between a closed position on the one side and an open position on the other side of the base member. In the closed position, an annular space is formed for the wound cord.

A delivery reel for an elongated sheet, having a disk-shaped flange member on which a sheet roll is positioned; an auxiliary core member of generally cylindrical shape split in the circumferential direction to enable expansion in diameter, and inserted into the inside diameter part of the sheet roll; a main core member fitted into the auxiliary core member which has been inserted into the sheet roll; and a stopper member attached to the circumferential edge of the flange member, and jutting toward the outside in the radial direction. The main core member has a plate spring. In a state in which the auxiliary core member has been inserted into the inside diameter part of the sheet roll, and the main core member has been fitted into the auxiliary core member, the plate spring presses the inside peripheral surface of the auxiliary core member toward the outside in the radial direction.

A trimmer head assembly for a trimming machine. The trimmer head assembly includes a spool. The spool has a central tubular hub. The spool also has a central flange that radially extends from the hub. A trim line conduit is joined to the central flange. The trim line conduit has a first open end. The first open end leads to a first straight section. The first straight section leads to a curved central section. The curved central section leads to a second straight section. The second straight section leads to a second open end. The curved central section passes around the center of the spool. A housing is provided that receives the spool therein. When loading trimmer line into the trimmer head assembly, the shape of the conduit enables the trimmer line to pass around the central opening in the spool without binding.

There are provided a wind-up drum that is easily detached in a state in which a wound tape is fastened, a tape feeder including the wind-up drum, and a component mounting machine capable of mounting the tape feeder. A wind-up drum includes a tape holding member including an insertion hole for inserting a support shaft of a rotating device and configured to hold a wound tape, and a wound member attached to the tape holding member, configured to wind up the tape by rotating the support shaft by the rotating device in a state in which the support shaft is mounted, and including a rotating member that rotates in contact with the support shaft when the wound member is detached from the support shaft in a state in which the tape is wound.

The present disclosure relates to an ergonomic tape holder onto which a roll of tape is mounted and secured. In particular, the ergonomic tape holder is a single-piece and unitary constructed apparatus having vertical towers disposed on a fixed based which prevents the roll of tape from shifting, rolling, or moving about the base.

A binding tape (10) includes an intermediate layer (11), and a first surface layer (16) covering one surface of the intermediate layer (11). The intermediate layer (11) has a plurality of first linear members (12) arranged side by side at an angle with respect to a longitudinal direction (D1) of the binding tape (10).
