[0011] On the other hand, when a transparent touch panel is pasted on the transparent part of the tray-shaped member, the transparent touch panel with a surface-adhesive transparent adhesive sheet is laminated on the transparent part of the tray-shaped member, so it is easy to mix microscopic particles between the two. Air bubbles, mixed air bubbles cause color spots on the display part and become defects

Embodiment Construction
[0029] Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings.
[0030] figure 1 It shows a transparent touch panel as a functional film and a case as a tray-shaped member pasted by the functional film pasting device of the present invention.
[0031] In this figure, the casing 1 is a part that constitutes the display part of the mobile phone. The central part of the transparent touch panel sticking range (hereinafter referred to as the sticking range) S surrounded by dotted lines is transparent, and the outside of the central part and the sticking range are transparent. The outer side of the S can be decorated into a window frame shape by, for example, in-mold molding (Japanese original: インモルドランド) to shield the circuits, components, etc. provided inside the case.
[0032] In addition, S' in the figure represents the pasting surface shape (rectangular planar shape in this embodiment).

A device for sticking a functional film comprising a moving stand (21) arranged to position a tray component (1) with a transparent part and to move substantially in the horizontal direction, a transparent functional film positioning mechanism which positions a transparent functional film with a transparent adhesive sheet with respect to the tray component (1) positioned on the moving stand such that the transparent adhesive sheet faces the transparent part, and a stick mechanism for sticking the transparent functional film to the transparent part of the tray component (1), wherein the sticking mechanism comprises a guide standing substantially in the vertical direction, a movable frame (13) elevating / lowering along the guide, an idle shaft (20b) provided below the movable frame and idling about a horizontal axis in the direction intersecting the moving direction of the moving stand perpendicularly, and a resilient press portion (20c) formed to protrude in the circumferential direction along the outer circumferential surface of the idle shaft, and the resilient press portion is configured to have a developed shape matching the planar shape of the sticking range of the transparent functional film.
Description
technical field [0001] The present invention relates to a device for pasting functional films and a method for pasting functional films. The sticking device and sticking method are suitable for sticking a transparent functional film on the inner surface of a transparent shell constituting a display part of a small electronic device and integrating it with the transparent shell. Background technique [0002] Conventionally, a display device with an input function has been used in which a transparent touch panel is laminated on a display screen such as a liquid crystal display device to arrange it, and an icon or the like displayed on the display screen can be directly selected by touching the transparent touch panel with a finger. desired function. As the transparent touch panel, as described in Japanese Patent Application Laid-Open No. 2003-511799, there are known a resistive film type, a capacitance combination type, and the like. [0003] The capacitance combined type tr...
