Abstract

PURPOSE:To make the equipment convenient for housing and carrying by devising this equipment such that an earphone-microphone is pulled out from the radio equipment main body when it is in use and the earphone microphone is housed when it is not in use. CONSTITUTION:The earphone-microphone 1 consists of a couple of an earphone 1a and a microphone 1c. A connection cable 2 is taken up to the shaft 9 of a rotary body 8 and the earphone-microphone 1 is housed in a container recessed part 28. When the earphone-microphone 1 is in use, the operation section 35 of a cover 29 is lifted up to escape a projection 33 from a recessed part 32 and turned toward the cover 29 to open a housing port 27. Talking is attained without putting the radio equipment main body 3 in hand by pulling out the earphone microphone. In the case of carrying the radio equipment after it is used, the rotary body 8 is turned to take up the cable 2 onto the shaft 9, the earphone-microphone 1 is housed in the housing recessed part 28, the cover 29 is turned to engage the projection 33 and the recessed part 32 with each other resulting in choking the housing port 27. Thus, the operability is improved and missing of the earphone microphone is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a portable wireless device, and more particularly to a storage device for an earphone microphone thereof.

2. Description of the Related Art As a conventional portable radio device, a configuration is known in which an earphone microphone is separably connected to a jack on the main body of the radio device. Hereinafter, the above conventional example will be explained with reference to the drawings.

FIG. 5 shows a conventional portable radio device, and is a perspective view of the earphone microphone separated from the main body of the radio device. As shown in FIG. 5, the earphone microphone 51 includes a pair of earphones 51a for earmuffs connected by a head-mounted band 51b, and a microphone 51c connected by a support member 51d. This earphone microphone 51 is electrically connected to a plug 52 via a connecting cable 53. On the other hand, a jack 56 is fixed to the casing 55 of the radio main body 54 to be electrically connected to an internal matching board (not shown) and to be electrically connected to the plug 52 by insertion.

Next, the operation of the above conventional example will be explained.

The plug 52, which is electrically connected to the earphone microphone 51 via the connection cable 53, is inserted and connected to the jack 56 of the radio main body 54, the band 51b is worn on the head, and the earphone 51a is placed in the ear. By arranging the microphone 51c at the mouth, it is possible to make a call without holding the main body 54 of the radio. In addition, when carrying a portable radio or not using it, store the portable radio in a pocket etc.
When carrying this stored state, the plug 52 is removed from the jack 56 and the earphone microphone 51 and the like are separated from the radio main body 54, thereby making it easier to store and carry.

Problems to be Solved by the Invention However, in the above-mentioned conventional portable radio device, the plug 52, which is electrically connected to the earphone microphone 51 via the connection cable 53, and the jack 56 of the radio device body 54 are inserted. Therefore, when storing the portable radio in a pocket or the like, it is necessary to separate the radio main body 54 and the earphone microphone 51, which is cumbersome to operate. If the earphone microphone 51 is separated from the radio main body 54, there is a risk of losing the earphone microphone 51, resulting in an extremely inconvenient configuration for the user.

The present invention solves such conventional problems by making it possible to pull out the earphone microphone from the radio body when it is used, and store it inside the radio body when it is not in use. , making it easier to carry, improving operability when using and not using the earphone microphone, and setting the length of the connection cable to suit the intended use of the earphone microphone. It is an object of the present invention to provide a portable wireless device that can be used and furthermore prevent the earphone microphone from being lost.

Means for Solving the Problems In order to achieve the above object, the present invention provides an earphone microphone, a connection cable and connection means for electrically connecting the earphone microphone to a radio main body, and a connection cable and a connection means formed on the radio main body. a recess for storing the earphone microphone and a recess for storing the earphone microphone, rotatably supported by the radio main body, winding up or unwinding the connection cable, and storing the earphone microphone in the storage recess of the radio main body; It is equipped with a rotating body for pulling it out of the storage recess.

and the connecting means is attached to the rotating body,
