Waterproof electronic appliance

A waterproof electronic appliance, comprising:

• a casing including a bottom panel, a top panel, and a side wall, the side wall being divided into an upright wall adjacent to the bottom panel and a vertical wall adjacent to the top panel;
• a first double-sided adhesive tape being adhered on a top end surface of the upright wall;
• a second double-sided adhesive tape being adhered on a bottom end surface of the vertical wall;
• and
• a cable including signal lines and a tube covering the signal lines, the cable extending from inside to outside of the casing through the upright wall and the vertical wall;
• wherein the first and second double-sided adhesive tapes adhere to an outer surface of the tube sandwiched between the upright wall and the vertical wall, and the adhesive tapes adhere to each other in an area adjacent to the sandwiched tube.

A method of waterproofing an electronic appliance, comprising:

• providing a casing including a bottom panel, a top panel, and a side wall;
• dividing at least a part of the side wall into an upright wall adjacent to the bottom panel and a vertical wall adjacent to the top panel;
• surrounding the bottom panel and the top panel with the side wall;
• forming an inner space with the side wall, the bottom panel, and the top panel;
• adhering a surface of a first double-sided adhesive tape to a top end surface of the upright wall;
• extending the first double-sided adhesive tape along the top end surface of the upright wall;
• adhering a surface of a second double-sided adhesive tape to a bottom end surface of the vertical wall;
• extending the second double-sided adhesive tape along the bottom end surface of the vertical wall;
• providing a cable including signal lines;
• extending the cable from an inside to an outside of the casing through the upright wall and the vertical wall;
• sandwiching the cable between the upright wall and the vertical wall;
• providing a tube having a flat shape extending in a direction in which the top end surface of the upright wall and the bottom end surface of the vertical wall extend;
• disposing the tube at a part of the cable sandwiched between the upright wall and the vertical wall;
• covering the signal lines with the tube;
• adhering the first and second double-sided adhesive tape to an outer surface of the tube at the part of the cable sandwiched between the upright wall and the vertical wall;
• and
• adhering the adhesive tape to each other in an area adjacent to the sandwiched part.
