Abstract
A binding component holding sheet is configured to detachably hold a binding component obtained by spirally winding a wire rod and includes a holder configured to hold the binding component by insertion of a circumferential portion of the spirally wound binding component. The holder is configured to hold the binding component so that an area greater than a half of the binding component in a circumferential direction protrudes to one side of the binding component holding sheet and an area less than the half of the binding component in the circumferential direction protrudes to the other side of the binding component holding sheet.
Claims21
A binding component holding sheet configured to detachably hold a spirally wound binding component which includes a spirally wound wire rod, with the spirally wound binding component detachable from the holding sheet in a radial direction of the spirally wound binding component, the binding component holding sheet comprising:
- a holder configured to hold the spirally wound binding component with a circumferential portion of the spirally wound binding component inserted through the binding component holding sheet,
- wherein the binding component holding sheet includes a first side and a second side opposite the first side,
- wherein the spirally wound binding component includes an axis about which the wire rod is spirally wound, and a circumference having a circumferential area when viewed in a direction normal to the axis, and wherein the circumferential area includes a first portion and a second portion, and
- wherein the holder holds the spirally wound binding component so that the first portion of the circumferential area protrudes from the first side of the binding component holding sheet and the second portion of the circumferential area protrudes from the second side of the binding component holding sheet, and wherein the first portion of the circumferential area is greater than one-half of the circumferential area and the second portion of the circumferential area is less than one-half of the circumferential area.
A binding component holding sheet configured to detachably hold a spirally wound binding component which includes a spirally wound wire rod, with the spirally wound binding component detachable from the holding sheet in a radial direction of the spirally wound binding component, the binding component holding sheet comprising:
- the binding component holding sheet including a first side and a second side opposite to the first side;
- and
- an escape hole located in the binding component holding sheet and configured to expose the spirally wound binding component in a position protruding from the first side and the second side of the binding component holding sheet with a circumferential portion of the spirally wound binding component inserted through the escape hole,
- wherein the spirally wound binding component includes an axis about which the wire rod is spirally wound, and
- wherein the escape hole has a length in a direction of the axis of the spirally wound binding component corresponding to multiple turns of the spirally wound binding component.
