Problems solved by technology

However, some devices do not form recesses on panels or sheets due to emphasizing on developing a good appearance design, etc.
making it difficult to remove panels or sheets
Even if the panel or sheet can be removed, it will be damaged
Also, special tools are often required for disassembly, which in some cases increases cost and requires a high level of disassembly skill

[0015] 1A and 1B show the appearance of the foldable cellular phone 1. As shown in FIG. FIG. 1A shows an opened cellular phone 1 viewed from the operation panel side. The cellular phone 1 includes a main body unit 10 and a display unit 20 . The display unit 20 is engaged with the main body unit 10 through the opening / closing unit 61 . The main body unit 10 has many keys 11 . Keys 11 are operated by the user to input various information such as telephone numbers. The microphone 12 is provided at a lower end portion of the main body unit 10 . In addition, the display unit 20 is equipped with a transparent front cover that allows a user to see display contents therethrough. An earpiece 26 for outputting sound is provided on the upper portion of the display unit 20 .

[0016] Figure 1B Shows an open folded cellular phone viewed from the back side. The rear cover 31 of the main body unit 10 of the cellular phone 1 is provided on the rear side of the main body unit 10 , and ...

[0035] Figure 8 is an explanatory diagram of the casing 2 of the display unit 20 of the cellular phone 1 according to the second embodiment. Figure 8 It is shown how the back cover 41 is attached to the base unit 51 of the display unit 20 of FIGS. 1A and 1B . Figure 8 shows from Figure 1B Housing 2 seen from the back side. The double-sided tape 42 is used as an adhesive material for attaching the rear cover 41 to the base unit 51 . In addition, the film tube 43 is used to detach the rear cover 41 from the base unit 51 . The rear cover 41, the double-sided tape 42, and the film tube 43 are the same as those of the first embodiment. The base unit 51 is the same as the first embodiment except that the pipe holding groove 44 is not provided.

[0036] Next, how to assemble the elements located between the rear cover 41 and the base unit 51 will be described. First, the double-sided tape 42 is attached to the bonding surface of the base unit 51 . Then, the film tube 43 is...

Abstract

A casing includes an adhesive member, a pair of casing members bonded together with the adhesive member, and a tube including a fluid inlet and having an elasticity. And the tube expands along with injection of a fluid into the tube from the fluid inlet to detach the bonded casing members based on an expansion force of the tube.

Description

technical field [0001] The present invention relates to a structure for efficiently detaching a case member attached to an electronic device. Background technique [0002] Heretofore, bonding methods using screws, double-sided tapes, or adhesives are often used for the assembly of resin panels or metal sheets of electronic devices. In order to detach the resin panel or metal sheet, a method of loosening a screw and detaching the panel or sheet or a method of directly applying an external force to the panel or sheet to detach the panel or sheet is used. However, in the case of screwing panels or sheets, if a plurality of screws are used for the panels or sheets, it is troublesome to assemble or disassemble the panels or sheets. In addition, this structure of screw connection cannot be applied to small electronic devices. In addition, in the case of directly applying an external force to a resin panel or a metal sheet for detachment, if a concave portion for applying externa...
