Part, a high-intensity LED that is covered with a transparent cover and emits light when receiving a signal, a power switch and a mode changeover switch that is also used as a power switch, a buzzer or vibrator that rings when receiving a signal, and at least a power supply The above mode is characterized in that sound or vibration can be adopted in addition to the two elements of light emission and character display, and in addition to the power capacity confirmation switch, a time display switch and an alarm switch are arranged in part of the casing. A part of the casing described above is provided with an L for confirming the power capacity. Characterized in that D is provided, the power source described above is characterized in that the power supply by the battery and AC adapter is used.

  The portable receiver according to the present invention is configured as described above. Therefore, the receiver main body can be carried in a pocket or the like, and when an incoming call is received, a vibration or high-brightness LED emits light (flashes), and a message of characters or symbols is displayed. Further, it can be used as a clock at all times, and in addition to checking the time, it can also notify the arrival (elapsed time) of the set time by an alarm, so that it functions as a wake-up.

  Due to the above effects, the use of the system itself mainly for hearing-impaired people can be widely used for healthy people in noisy places, and its application can be broadened. The ease of use is also very good.

  This was realized by configuring as in the embodiment shown in the drawings.

  Next, an example of a preferred embodiment of the present invention will be described with reference to the drawings. 1 is a front view showing a portable receiver embodying the present invention, FIG. 2 is a rear view, FIG. 3 is a plan view, FIG. 4 is a left side view, FIG. 5 is a right side view, and FIG. It is also a block circuit diagram.
