Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a telephone handset. This handset for telephones is typically used as the slave unit of a cordless telephone device including a master unit and a slave unit.

[0002]

[Prior Art]

 As shown in FIGS. 2, 3, and 4, a telephone handset used as a slave unit of a cordless telephone device generally has a handset body 10 and an antenna 10 ′ protruding from the handset body 10 to the outside.

Referring to FIG. 5 in addition to FIG. 2, FIG. 3, and FIG. 4, a conventional telephone handset is provided in a handset main body 10 and emits illumination light in response to a drive signal. It has a light emitting element 11 that emits light, for example, an LED (light-emitter diode), and an optical display unit 12 that is provided in a predetermined portion of the handset body 10 and that transmits the illumination light. The light emitting element 11 emits blinking light as illumination light when the cordless telephone device is called. In addition, for example, when the slave is talking, continuous light is emitted as illumination light. As the optical display unit 12, for example, a transparent or translucent panel or the like is used.

[0004]

[Problems to be solved by the device]

 The directivity of the illumination light emitted from one light emitting element 11 is limited to a predetermined range as shown in FIG. In the handset for the present telephone, the light emitting element 11 has a directivity center direction D 1 of the illumination light substantially on the inner surface of the optical display unit 12 so that the illumination light in a limited range all enters the optical display unit 12. It is placed so that it is perpendicular to. As described above, in the handset for this telephone, the light emitting element 11 is used as a point light source that emits illumination light in a limited range, and the range 12a where the optical display unit 12 emits surface light is emitted by the point light source. It depends on the illumination light in a limited range. Therefore, in the above-mentioned handset for a telephone using one light emitting element 11, the area 12a where the optical display section 12 emits surface light does not become large, and it cannot be said that the notification effect by the optical display is large. Therefore, as shown in FIG. 6, it is conceivable to use a plurality of light emitting elements 11 to increase the surface emission range 12a of the optical display section 12. However, in this case, since a plurality of light emitting elements 11 are used, the cost is high and the manufacturing process is complicated.

An object of the present invention is to provide a handset for a telephone, which is low in cost and has a large optical notification effect. Another object of the present invention is to provide a handset for a telephone, which is capable of enlarging the range of surface light emission of an optical display unit at low cost.

[0006]

[Means for Solving the Problems]

 According to the present invention, a handset main body, a light emitting element that is provided in the handset main body and emits illumination light in response to a drive signal, and a predetermined portion of the handset main body that transmits the illumination light. In a handset for a telephone having an optical display unit, a reflection provided in the main body of the handset, which reflects the illumination light as reflected light, guides the reflected light to the optical display unit, and transmits the reflected light to the optical display unit. A telephone handset featuring a plate is obtained.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 1, a telephone handset according to one embodiment of the present invention includes similar parts designated with like reference numerals. The telephone handset further includes a reflector 13 provided in the handset body 10. The reflection plate 13 reflects the illumination light emitted by the light emitting element 11 as reflected light, guides the reflected light to the optical display unit 12, and transmits the light to the light display unit 12. The reflection plate 13 is, for example, a white plate or a plate having a reflective surface with a relatively high reflectance.

The optical display unit 12 receives the illumination light emitted by the light emitting element 11 as direct light and the reflected light reflected by the reflection plate 13 as indirect light.

In the illustrated example, the light emitting element 11 and the optical display unit 12 are arranged so that the directivity center direction D of the illumination light emitted by the light emitting element 11 and the inner surface of the optical display unit 12 form an acute angle. It is arranged so that the direct light from the light emitting element 11 is sent out toward the range 12a of the optical display section 12, and the reflected light from the reflection plate 13 is also sent out toward the range 12a of the optical display section 12. ing. That is, in this example, the reflected light (indirect light) is reflected by the light emitting element 11 and the reflector 13 which are arranged so that the direction D of the directivity of the illumination light forms an acute angle with the inner surface of the optical display unit 12. A surface light source that emits light) toward a wide range 12a of the optical display unit 12 is configured. As described above, in the handset for this telephone, the light emitting element 11 and the reflecting plate 13 constitute a surface light source that emits reflected light over a wide area in the optical display section 12, and as a result, one light emitting element is formed. By using the element 11, the range 12a in which the optical display unit 12 emits light can be increased, and the notification effect by the optical display becomes large.

[0010]

[Effect of the device]

 As described above, according to the present invention, it is possible to use not only the direct light of the illumination light emitted by one light emitting element but also the direct light with a simple structure in which a reflector is combined with one light emitting element. In this way, a handset for telephone can be obtained in which the range of surface light emission of the optical display unit is increased and the notification effect by the optical display is large.
