As shown in these figures, the IC card of this embodiment includes a card-type device body 1. This device body 1 is
It is composed of a flat frame 1a and a pair of front and back surface panels 1b, 1b attached to both front and back surfaces of the frame 1a in a sticking manner. A storage chamber 2 for the battery B is formed in the device body 1, and a lid 3 for holding the battery B in a fixed position in the storage chamber 2 is detachably provided to the device body 1. ing.

As clearly shown in FIGS. 3 and 4, the storage chamber 2 extends from the edge opening 4 of the device body 1 into the thickness of the device body 1 (that is, between the pair of front panels 1b, 1b). It is formed so as to be recessed so that the battery B can be inserted into the inside of the apparatus main body 1 (in the direction of arrow a) from the edge opening 4. The inner part of the storage chamber 2 is a set part of the battery B, and a pair of contacts 5 and 6 respectively contacting the positive electrode and the negative electrode of the battery B are provided in the inner part. Of these, the contact 5 on the anode side elastically contacts the peripheral portion of the battery B, which is the anode, and presses the battery B in the direction opposite to the insertion direction B.

A portion between the inner portion of the storage chamber 2 and the edge opening 4 is a battery insertion passage 2a. Then, of the respective portions of the front surface panel 1b on the rear surface side, the portion facing the passage 2a is cut out to form an open portion 7 communicating to the outside of the rear surface. This open part 7
Is continuous with the edge opening 4 with the same width as the edge opening 4 and the passage 2a.

In addition, insertion recesses 8 are formed on both sides of the passage 2a for attaching and detaching the lid 3 in the thickness direction b of the apparatus body 1. The insertion recessed portion 8 is formed to a depth reaching from the front surface panel 1b on the back surface side to the other front surface panel 1b, the bottom portion thereof widens toward the edge opening 4, and the locking step is formed at the corner of the widened portion. The part 9 is formed. Reference numerals 10 are guides that regulate the front and back of the inserted battery B, and are provided on both sides of the passage 2a.

The lid 3 is fitted in the passage 2a to close the edge opening 4 and the opening 7, and holds the battery B in the storage chamber 2. The main portion of the lid 3 is large enough to fit in the passage 2a. It has A pressing portion 3a for the battery B is formed on the inner surface of the lid body 3. Further, a pair of protrusions 3b, 3b are formed on both sides of the lid 3 so as to project, and a hook 3c bent toward the outer end side of the lid 3 is formed on a part of the protrusion 3b. ing. The protrusion 3b having the hook 3c can be inserted into the insertion recess 8 on the side of the device main body 1 in the thickness direction b of the device main body 1, and in the state of being inserted into the insertion recess 8, the electronic insertion direction i By displacing in the opposite direction, that is, toward the end edge opening 4 side, the hook portion 3c is inserted and the locking step portion 9 on the insertion recess 8 side.
Is adapted to engage with. Further, a thin plate-shaped insertion edge 3d is provided at the tip of the lid 3, and the insertion edge 3d is provided in a gap 11 formed between the front panel 1b and the frame 1a on the battery set position. It is insertable and closes a part of the opening 7 in a state of being engaged with the front panel 1b.

Next, the operation of the above configuration will be described.

When the battery B is loaded, the battery B is inserted into the storage chamber 2 with a predetermined front and back direction. When the battery B is inserted into the inner part of the storage chamber, the electrodes 5 of the battery B respectively have corresponding contacts 5,
6 contacts. After that, the lid 3 is fitted and the battery B is fixed at a predetermined set position. The lid 3 is fitted as follows.

First, insert the insertion edge 3d of the lid 3 into the gap on the battery set position.
While inserting into 11, the pressing portion 3a is applied to the peripheral portion of the battery B, and the battery B is pushed further in. Since the battery B is received by the contact 5 having a spring property, the battery B is slightly displaced to the inner part of the storage chamber 2 by the pressing of the pressing portion 3a.

When the lid 3 is displaced in the battery insertion direction B while pushing the battery B in this way, the position of the protrusion 3b and the insertion recess 8 on the apparatus main body 1 side are aligned, and the protrusion 3b is inserted into the insertion recess 8. Can be plugged into. Then, the protrusion 3b is inserted into the insertion recess 8. With this, the lid 3 is fitted into the passage 2a to close the passage 2a.

When the protrusion 3b is inserted to the bottom of the insertion recess 8 and the operation force is removed, the lid 3 is moved in the direction opposite to the battery insertion direction i, that is, at the end by the elasticity of the contact 5 acting via the battery B. It is slightly slid to the edge opening 4 side. By this displacement, the hook portion 3c which is a part of the protrusion 3b is engaged with the locking step portion 9 on the passage 2a side. By this engagement, the lid 3 is prevented from slipping out in the thickness direction of the apparatus body. Further, since the protrusion 3b is inserted into the insertion recess 8, the lid 3 does not come out in the direction opposite to the battery insertion direction B.

In this way, the lid 3 is fitted to the device body 1 by two-stage displacement of the device body 1 in the thickness direction (b) and the battery insertion / removal direction. It does not come off from the device body 1. Since the lid body 3 is not displaced in the two steps by the impact from the outside, the lid body 3 does not come off due to the impact from the outside.

When taking out the battery B, first, the lid 3 is slightly slid in the battery insertion direction B. By this displacement, the engagement between the hook portion 3c and the locking step portion 9 is released, and the protrusion 3b can be removed from the insertion recess 8, that is, the lid 3 can be removed from the passage 2a.

Therefore, the lid 3 is pulled outward in the thickness direction of the apparatus body 1. Then, the protrusion 3b comes out of the insertion recess 8, so that the lid 3 can be separated from the apparatus main body 1. When the lid 3 is removed, the passage 2a is opened and the battery B can be taken out.

The present invention is not limited to the IC card, and can be applied to other card type electronic devices that require a battery.

In this embodiment, however, the spring property of the contact 5 makes the lid 3
Although the elastic force is applied in the direction opposite to the battery insertion direction a, the pressing portion 3a of the lid 3 is provided with a portion that is elastically deformed, and the elastic deformation portion causes the lid 3 to move in the battery insertion direction a. May be made to act in the opposite direction.

<Effects of the Invention> As described above, according to the present invention, the lid body is fitted to the device body by two-stage displacement, that is, displacement in the thickness direction of the device body and displacement in the battery insertion / removal direction. Since the body is not displaced in two steps due to the impact from the outside, the lid does not come off due to the impact from the outside, and therefore the battery does not drop off unexpectedly.
