ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an incoming call indicator for a portable phone, in particular, it relates to an incoming call indicator for a portable phone having an antenna attached to a phone main body, projecting therefrom.
Portable phones comprise an incoming call indicator for visually confirming an incoming call in addition to the advice by a call sound or vibration.
Conventional incoming call indicators have been provided originally either in the front surface or in the upper surface of a portable phone. Although the structure is simple, it also involves a problem in that the incoming call indicator can hardly be seen depending on the state of the portable phone in use. As an incoming call indicator for solving the problem, for example, those disclosed in JP-A-4-121142U and JP-B-4-41643U are known.
FIG. 4
shows an incoming call indicator according to the technique of JP-A-4-121142U, comprising an antenna
51
mounted on a phone main body
50
, projecting therefrom, a light transmissible member
52
provided around the outer periphery of the base end part of the antenna
51
, with the upper part of the light transmissible member
52
projecting from the phone main body
50
as well as the lower part
52
a
disposed inside the phone main body
50
, a light introducing part
53
provided in the lower part
52
a
of the light transmissible member
52
, and a light emitting element
54
disposed facing to the light introducing part
53
. According to the configuration, since the light transmissible member
52
is disposed around the outer periphery of the base end part of the antenna
51
, the entirety of the base end part of the antenna
51
can emit a light. Therefore, the user can observe the light emission from the light transmissible member
52
visually from anywhere as long as the phone main body
50
can be seen.
FIG. 5
shows an incoming call indicator according to the technique of JP-B-4-41643U, comprising a light transmissible member
63
mounted across the upper surface
61
and the front surface
62
of a phone main body
60
. Therefore, the light emission from the light transmissible member
63
can be observed visually even in the case the phone main body
60
is placed on a desk or attached to a belt.
However, according to the incoming call indicator of JP-A-4-121142U, since the light transmissible member
52
is fitted around the outer periphery of the antenna
51
, it is difficult in terms of the structure design.
In contrast, according to the incoming call indicator of JP-B-4-41643U, due to the limitation of the light transmissible member
63
shape, the light can be emitted only to the two directions, that is, to the upper surface
61
and the front surface
62
. Therefore, depending on the state of use, the light emission from the light transmissible member
63
may not be observed visually. That is, the light emission visible range is narrow.
SUMMARY OF THE INVENTION
In view of the above-mentioned problems, an object of the invention is to provide an incoming call indicator for a portable phone with a simple configuration, having a wide light emission visible range for allowing preferable visible observation of the incoming call state.
In order to achieve the above-mentioned object, an incoming call indicator for a portable phone according to the invention comprises an antenna main body projecting from a portable phone main body, a light transmissible member disposed so as to be exposed circumferentially between the base end part of the antenna main body and the portable phone main body, a light guiding member disposed inside the portable phone main body, with a light outputting part provided on one end, facing to the light transmissible member, and a light emitting element disposed facing to a light inputting part provided on the other end of the light guiding member for emitting a light according to an incoming call signal.
Moreover, it is preferable that the light transmissible member comprises an elastic ring-like member having a sealing function for preventing entrance of water from the gap between the antenna main body and the portable phone main body.
Furthermore, it is preferable that the light transmissible member comprises an elastic member having an attachment loosening prevention function in the part with the antenna main body attached to the portable phone main body.
In the above-mentioned configuration, a light from the light emitting element is inputted to the light inputting part of the light guiding member so as to be guided to the other end and outputted to the outside from the light outputting part of the light guiding member via the light transmissible member. Since the light transmissible member is provided circumferentially between the base end part of the antenna main body and the portable phone main body, the outer periphery of the antenna base part emits a light at the time of incoming call according to an incoming call signal. Therefore, the user can easily recognize the light emission from the incoming call indicator visually from anywhere as long as the phone main body can be seen. Moreover, owing to the simple configuration of disposing the light transmissible member between the antenna main body and the portable phone main body and providing the light guiding member in the portable phone main body, the structure design and the assembly operation can be facilitated.
Furthermore, since the light transmissible member comprises a ring-like member having elasticity, such as rubber so as to serve as a sealing member, it can serve also as a rubber ring for providing the watertight structure in the antenna part, and thus increase of the number of components can be prevented. Moreover, since the light transmissible member comprises a member having elasticity, such as rubber, pressure and friction force can be added to the part with the antenna attached, and thus loosening of attachment of the antenna main body can be prevented.
