Embodiments of the present invention will be described below with reference to the accompanying drawings. Here, FIG. 1 is a perspective view of an in-ear hearing aid to which the button-type battery housing structure according to the present invention is applied, FIG. 2 is a perspective view of an in-ear hearing aid with a battery holder removed,
FIG. 3 is a partial cross-sectional perspective view of the in-ear hearing aid, FIG. 4 is a perspective view of the in-ear hearing aid in a state where the button battery is placed in the opening,
FIG. 5 is an operation explanatory view of the button-type battery storage structure according to the present invention.

As shown in FIG. 1, in an in-ear hearing aid to which a button-type battery housing structure according to the present invention is applied, a case body 3 is formed by a resin shell 1 and a face plate 2. Battery compartment 5 for storing button-shaped battery 4
Is provided. Further, inside the case body 3, components constituting a hearing aid such as a microphone, a hearing aid processing unit, and an earphone are arranged.

The face plate 2 has an opening 6 for loading the button-type battery 4 into the battery housing 5.
Further, the shaft member 7 erected near the edge 6a of the opening 6 includes
A battery holder 8 that holds the button type battery 4 and stores it in the battery storage section 5 is rotatably attached. Reference numeral 9 denotes a main volume, 10 denotes a semi-fixed trimmer, 11 denotes a microphone cover, 12 denotes a semi-fixed trimmer, and 13 denotes an electrode piece provided in the battery housing 5.

As shown in FIGS. 1 and 3, the battery holder 8 is made of an elastic resin, and has a bottom member 8a which contacts the upper surface 4a or the bottom surface 4b of the button type battery 4, and an outer peripheral surface of the button type battery 4. It has a wall portion 8b provided along the periphery 4c, a rotating groove 8c engaged with the shaft member 7, and a projection 8d for hooking a fingertip to open the battery holder 8. When the battery holder 8 is closed, the wall surface portion 8b covers the opening 6 and functions as a lid of the battery housing portion 5.

The wall portion 8b of the battery holder 8 is formed so as to extend over a half of the outer circumference of the button type battery 4 in order to securely hold the button type battery 4. The button battery 4 is mainly held at both ends 8e and 8f of the wall 8b.

When the battery holder 8 is opened,
When the button-type battery 4 is placed so that its outer peripheral surface 4c covers the opening 6 of the battery housing 5, the outer peripheral surface 4c of the button-type battery 4 is placed on the edge 6b of the opening 6 and the end 8e of the wall surface 8b. Abuts. Further, when the button-shaped battery 4 is pushed into the battery housing 5, the position of the edge 6 b of the opening 6 and the position of the end 8 e of the wall 8 b are adjusted so that the battery holder 4 rotates in the direction of closing. The position of the rotation groove 8c of the battery holder 8 is set.

The end 6b of the opening 6 and the end 8e of the wall 8b are in tapered contact with the outer peripheral surface 4c of the button type battery 4 so that the button type battery 4 slides smoothly. It has been processed.

The loading and unloading operations of the button-type battery 4 in the button-type battery storage structure configured as described above will be described. First, in order to load the button type battery 4 into the battery storage section 5, the battery holder 8 is opened. Then, as shown in FIG. 4 or FIG. 5A, when the button-shaped battery 4 is placed in the opening 6 so as to close the opening 6 with the outer peripheral surface 4c of the button-shaped battery 4, the outer periphery of the button-shaped battery 4 is The surface 4c contacts the edge 6b of the opening 6 and the end 8e of the wall 8b.

Next, when the battery holder 8 is pushed into the battery housing 5 by applying a force with a finger in the direction of arrow A, the button-shaped battery 4 closes the end 6b of the opening 6 as shown in FIG. The end 8e of the battery holder 8 is pushed down while sliding, and the battery holder 8 starts rotating around the shaft member 7. Further, FIG.
As shown in (c), the battery holder 8 starts to hold the button-type battery 4 at both ends 8e and 8f of the wall portion 8b while rotating around the shaft member 7.

Next, when the button type battery 4 is pushed into the battery housing 5 with a fingertip via the wall portion 8b of the battery holder 8,
As shown in FIG. 5D, the battery holder 8 completely holds the button-type battery 4, and the button-type battery 4 is stored in the battery storage unit 5. Therefore, the button-shaped battery 4 is connected to the opening 6.
The button-type battery 4 can be easily stored in the battery storage section 5 with the button-type battery 4 held in the battery holder 8 by simply pressing the button-type battery 4.

Next, in order to take out the button-shaped battery 4 stored in the battery storage section 5, a fingernail is hooked on a projection 8d formed on the battery holder 8, and the battery holder 8 is turned to open. Move. Then, the button-type battery 4 held in the battery holder 8 appears from the battery housing 5.

Further, after the battery holder 8 is completely opened, the button type battery 4 is removed from the battery holder 8. Therefore, the button-shaped battery 4 can be easily taken out of the battery housing 5 by simply rotating the battery holder 8.

The operation for loading the button-type battery 4 into the battery storage section 5 is as follows: after the battery holder 8 is completely opened, the button-type battery 4 is held in the battery holder 8 as in the conventional case. By closing the battery holder 8, the button-shaped battery 4 can be stored in the battery storage unit 5 while being held by the battery holder 8.

Therefore, according to the button-type battery housing structure of the present invention, after the battery holder 8 is opened and the button-type battery 4 is held by the battery holder 8, the battery holder 8 is turned to the closed state. The button-type battery 4 can be easily stored in the battery storage portion 5 by simply performing the operation described above, or the button-type battery 4 can be easily pressed directly into the opening 6 when the battery holder 8 is in the open state. In addition, the button-type battery 4 can be easily stored in the battery storage section 5 while being held in the battery holder 8.

In the embodiment of the invention described above, the case where the button-type battery housing structure according to the present invention is applied to an in-ear hearing aid has been described. However, the present invention
If the button type battery 4 is used, the present invention can be applied to electronic devices other than the in-ear hearing aid.

[0021]

As described above, according to the present invention, even when the battery holder is opened and the button-shaped battery is held in the battery holder, the operation of simply turning the battery holder to the closed state is also possible. Even when the button-shaped battery is simply pushed directly into the opening when the battery holder is in the open state, the button-shaped battery can be easily stored in the battery storage portion with the battery holder 8 held. The loading operation of the battery into the battery housing can be reliably performed.
