Description

  The present invention relates to a mobile communication device and a manufacturing method thereof, and more particularly to a mobile communication device such as a mobile phone having a housing structure for notifying incoming calls by light and a manufacturing method thereof.

  2. Description of the Related Art In recent years, mobile communication devices represented by mobile phones have been required to have visibility and design properties that are differentiated from other similar products in addition to demands for multi-functionality. On the other hand, in a mobile communication device, as a means for notifying a user of an incoming call by means other than sound or vibration, a light emitting element is blinked, and light from the light emitting element is blinked and displayed through a display window provided on the housing via a diffusion lens. Has been done.

  Here, the above-mentioned general diffusion lens is made of milky white and is fitted or welded to another part of the casing with another piece. In some cases, the back side of the light-transmitting resin is printed to transmit light. In addition, as a recent technique, there is a case where it is manufactured by an in-mold method in which a resin and a printing film are simultaneously formed on a light transmitting portion of a casing.

  However, the structure in which the above light-transmitting resin and printing are combined to display the incoming call blinking is a very standard specification, and there has been no significant difference in visibility and design between companies.

  Therefore, in consideration of the above design requirements, the housing is conventionally formed integrally with the display window portion using the same resin material, which is transparent or translucent, and irregularities are formed on the inner surface excluding the display window portion. 2. Description of the Related Art Conventionally, there has been known a portable communication device provided with light emitting means for diffusing light emitted from a light emitting element that emits light in conjunction with the above-described unevenness to emit light from the entire housing (see, for example, Patent Document 1).
