INDUSTRIAL APPLICATION FIELD The present invention relates to a mobile phone. Note that the mobile phone used in the specification of the present invention also includes a cordless phone used on a boat.

Needless to say, the ultimate purpose of communication is to be able to immediately convey or exchange intentions or information with anyone at any time, from anywhere, and in addition to traditional fixed point-to-point communication, mobile communication is gradually gaining popularity. It is developing. Mobile communication is communication between mobile bodies such as ships, cars, and aircraft (including people) and general subscriber telephones, offices, etc., and communication between mobile bodies.In recent years, it has become a type of mobile communication. Mobile phones and cordless phones are being actively developed.

Miniaturization of mobile phones is important for operational purposes, and device manufacturing technology has progressed and small and inexpensive parts have been supplied, making it easier to miniaturize. Because of this necessity, ergonomic considerations are required, which in some ways hinders miniaturization. Under these circumstances, it is desired to achieve miniaturization of mobile phones while taking ergonomic considerations into consideration.

Conventional technology Generally, when using a telephone, the receiver is placed close to the ear and the transmitter is placed close to the mouth, so it is necessary to maintain a sufficient distance between the receiver and the transmitter, even for mobile phones. The mobile phone itself was somewhat tall and large.

Problems to be Solved by the Invention As mentioned above, in conventional mobile phones, the distance between the receiving part and the speaking part provided on the main body of the telephone was approximately equal to the distance between the user's ear and mouth. However, there was a problem that miniaturization was not sufficient. In addition, the manufacturing technology for the parts that make up mobile phones has progressed, and smaller and cheaper parts are now available1.
From this point of view, it is relatively easy to miniaturize mobile phones, but there is an ergonomic requirement to ensure approximately the distance between the ear and the mouth between the receiver and transmitter. This was a factor that hindered miniaturization.

The present invention has been made in view of these points, and its purpose is to ensure a sufficient distance between the receiving part and the transmitting part when using the telephone even if the main body of the mobile phone is sufficiently miniaturized. The aim is to provide a mobile phone that can perform

15.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a mobile phone equipped with a power source, a transmitting/receiving circuit, a microphone, and a speaker, in which the speaker is configured from an earphone, and the connection cord of the earphone is connected to the connection cord of the earphone. The cord is retractably housed in a take-up reel equipped with a locking mechanism that locks the cord at that position when the cord is pulled out to an arbitrary length, and an automatic winding mechanism that automatically winds up the connecting cord when the locking mechanism is released. Then, the take-up reel is attached to the phone body by inserting the earphone plug electrically connected to one end of the connection cord into the earphone jack provided on the phone body, and when the connection cord is wound in, the earphone is attached to the case surface of the take-up reel. It is configured by providing a fixing means for fixing it to.

Function When using a mobile phone, it is difficult to maintain a sufficient distance between the microphone and the earphone if the earphone is attached to the take-up reel, so the earphone is usually pulled out from the take-up reel and attached to the ear to make a call. When the telephone is not in use, the locking mechanism is released and the earphone connection cord is automatically wound into the take-up reel and stored. Furthermore, even when the earphones are housed, you can attach your ears to the take-up reel case and make calls just like you would with a regular handset.
