[Detailed description of the invention] This invention is small in radio, earphones such as TV.
Conventionally, Jack and Chord's earphones are accessories for the main unit, or jacks are used
by plugging them into the main unit ^ Therefore, when not using the earphones, there is no
storage place for the earphones, and it is time to use it There are many cases in which earphones
are often found searching for Toh, and it is best to lose the earphones in K, and this invention
solves 0 points here, too, and it is a radio in O. (2) The ear water taking-in device is built in the
television main body. A bobbin (21 Kt!) For winding the hn earphone cord (1) which will be
described in this embodiment. Earphones (4) K flowing pager Rt-To convey, the ends of the
earphone cords are connected so that the metal ring (3) 2 憾 is attached to the inner and outer
KIIL 9 and two contacts (i) which are in constant contact with this Housing f6) K mounted h8
bobbin (! ) Is pivoted by the small boat motor (9). Attach the manual switch ()) and limit switch
(8) near the earphone cord (1) outlet on the front of the case% (6). The earphone cord (11 is
wound up and opened to a small m4-tar circuit with a switch (γ). The earphone circuit is also
open because the limit switch (8) is held down by the earphones, and only the main speaker
(turn) works as shown in 2111. When using the F earphone cord, use the earphone (4) by hand!
Il! When the fil switch is turned on, the limit switch works, and the main speaker-1llQ circuit
is opened, and the earphone 3 circuit is closed so that only the earphone works. When the use of
the earphone is stopped, tl is pressed by the finger of the switch (γ) and the circuit of the small
lid motor (9) is closed by the circuit of wL3 and the bobbin (turning of the coil winds the
earphone cord (1) When all the earphone cords are taken up, the earphone (4) automatically

pushes the Bll of the switch (7) to stop the rotation of the small 114-ter (9), and at the same time
the earphone (4) turns the ε switch (押 す 2 Il to push the ship automatically! As shown in the
earphone circuit ars *, the main body speaker circuit is closed and only the main body speaker
(2) works. If KMR is applied so that only the earphone (4) comes out to the outside inside the
front of a television etc., the earphone (4) is always in the foot position and it becomes easy to
use, ie when using earphones, simply earphone t91 When the main body speaker comes out,
only the stop earphone works, when the use of the earphone is stopped, the switch (7 mm S 會
press the ear phone code takes up rt, ** r r and the same 4- to 4- small Il motor (9 ) Only stop
spit main body speaker works!
put out. Easy to use and earphone * 1. There is a fear that earphones may be lost as well. ○ Oa
use in an apartment or hospital etc. is also widely used to benefit from Oa.
