Laminating apparatus mounted with improved mechanism
View Patent ↗A laminating apparatus is composed of a thermo compression bonding section, a first bobbin holder and a second bobbin holder. The thermo compression bonding section pulls a laminating film having a member for forming a protective film out from a roll of the laminating film, which is wrapped around a core bobbin in a cylindrical shape, and overlaps the protective film on one surface of a card and thermally compresses the protective film against the one surface of the card so as to be bonded. The first bobbin holder includes a reel shaft, a fixed section having a plurality of contacting surface sections, which is fixed to the reel shaft and formed in different positions in a direction along the reel shaft, a movable section, which can selectively contact with one of the plurality of contacting surface sections of the fixed section so as to be movable along the reel shaft, and a mechanism, which links the movable section to the fixed section and is capable of controlling positional fluctuation of a protective film to be bonded on a card. The second bobbin holder includes a shaft and a holder section, which is movable along the shaft and braced up toward the movable section, wherein the first and second bobbin holders support the core bobbin at both end portions respectively so as to be rotatable around an axis of revolution of the core bobbin, and wherein the core bobbin is supported by the movable section and the holder section with being sandwiched between them.
1. A laminating apparatus mounted with an improved mechanism comprising:
(a) a thermo compression bonding section,
wherein the thermo compression bonding section pulls a laminating film having a member for forming a protective film out from a roll of the laminating film, which is wrapped around a core bobbin in a cylindrical shape, and overlaps the protective film on one surface of a card and thermally compresses the protective film against the one surface of the card so as to be bonded;
(b) a first bobbin holder, the first bobbin holder including
(1) a reel shaft,
(2) a fixed section having a plurality of contacting surface sections, which is fixed to the reel shaft, wherein the plurality of contacting surface sections are formed on the fixed section in different positions in the circumferential direction at an equal angular interval in a direction along the reel shaft,
(3) a movable section having positioning protrusions, wherein the positioning protrusions can selectively contact with one of the plurality of contacting surface sections of the fixed section by rotating the movable section around the reel shaft so as to be movable along the reel shaft, and further having a flange section provided with a contacting surface, which enables contact with one end portion of the core bobbin, and
(4) a mechanism, which links the movable section to the fixed section and is capable of controlling positional fluctuation of a protective film to be bonded on a card; and
(c) a second bobbin holder, the second bobbin holder including
(1) a shaft, and
(2) a holder section, which is movable along the shaft and braced up toward the movable section,
wherein the first and second bobbin holders support the core bobbin at both end portions respectively so as to be rotatable around an axis of revolution of the core bobbin, and
wherein the core bobbin is supported by the movable section and the holder section with being sandwiched between them while the one end portion of the core bobbin contacts the contacting surface of the flange section of the movable section.
2. The laminating apparatus as claimed in claim 1 , wherein the mechanism transmits revolution of the fixed section to the movable section and results in rotating the core bobbin.
