Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a wireless call receiver that receives a call signal from a wireless transmitter and rings a ringing tone.
[0002]
[Prior art]
This type of wireless call receiver has a built-in speaker for ringing and outputting a ringing tone, a commercial power source supplied from the outside is stepped down to operate an internal circuit, and a transformer for lighting a lamp is incorporated. The size of the receiver body is determined by the arrangement state of the speaker and the transformer. For this reason, the wireless call receiver has a problem that if the speaker and the transformer that meet the desired function and design specifications are selected, the entire size becomes large.
[0003]
In addition, when the desk-top type wireless call receiver is made thin, there is a problem that the arrangement position of the transformer is biased, the stability of the transformer is impaired, and it is easy to fall down.
[0004]
[Problems to be solved by the invention]
An object of the present invention is to provide a wireless call receiver which solves the above-described problems, can be downsized, is thin and smart, and has excellent stability.
[0005]
[Means for Solving the Problems]
The present invention has been proposed in order to achieve the above object, and the wireless call receiver according to claim 1 includes a speaker and a step-down transformer built in the receiver body. In a wireless call receiver that receives a ringing signal and rings a ringing tone, the receiver body has a two-piece vertical structure consisting of a front shell and a back shell. In addition to forming a rounded shape so that the thickness of the right side portions is reduced, the speaker is accommodated in a position offset to one side rather than the central portion of the receiver body, and a sound hole is formed. The structure is such that the step-down transformer is formed in a portion excluding the central portion and the step-down transformer is accommodated below the central portion of the receiver body.
[0006]
Therefore, since the outer shell is formed in a rounded shape so that the thickness of the left and right side portions is smaller than that of the central portion, the receiver main body can be made thinner. In addition, the speaker is housed in a position that is offset to one side of the center part of the outer shell, and a sound hole is drilled in the part other than the center part. Regardless, the receiver main body can be made compact, and the heavy step-down transformer is accommodated below the central portion of the receiver main body, so that the stability is good.
[0007]
According to a second aspect of the present invention, there is provided a wireless call receiver according to the first aspect, wherein a plurality of business lamps and a display unit for recording a business are provided in a central portion of the receiver body in combination. The business lamp is configured to be turned on when a call signal is received from a wireless transmitter corresponding to the service lamp.
[0008]
Therefore, the call from the wireless transmitter and the message can be detected by the sound from the speaker and the lighting of the message lamp, especially for the hearing impaired user and the noisy environment. Can detect calls and requests from vessels.
[0009]
According to a third aspect of the present invention, there is provided the wireless call receiver according to the first or second aspect, wherein a call reception lamp that emits light when a call signal is received from the wireless transmitter is provided at an upper central portion of the receiver body. Structure.
Therefore, when the call reception lamp emits light, the call from the wireless transmitter can be reliably detected.
[0010]
The wireless call receiver according to claim 4 is the push button structure according to claim 1 or 2, wherein the call reception lamp includes a light emitting lamp that emits light when receiving a call signal from a wireless transmitter. When the push button is pressed, the ringing tone and the light emission of the light-emitting lamp are stopped.
Therefore, after detecting the light emission of the call reception lamp, the light emission of the light emission lamp is stopped by pressing the push button, and the next call can be dealt with immediately.
[0011]
