Field of the Invention The present invention relates to a case consisting of an upper case and a lower case, a printed circuit board provided with a predetermined circuit on the lower surface of the upper case, and a button battery housed in the case. And an electronic device such as a remote control device.

[0002]

2. Description of the Related Art Conventionally, such an electronic apparatus is configured as shown in FIG. 3 in a remote control device, for example. That is, in FIG. 3, the remote controller 1 is arranged so as to be in contact with the upper case 2 and the lower case 3, the printed circuit board 4 provided on the inner lower surface of the upper case 2, and the lower surface of the printed circuit board 4. And a battery 5.

On the upper surface of the upper case 2, the upper ends of the operation buttons (not shown) mounted on the printed circuit board 4 are exposed, and the lower surface of the upper case 2 is closed by the lower case 3. It is designed to form a sealed internal space.

As described above, at least one operation button protruding upward is mounted on the printed circuit board 4, and a predetermined circuit required for remote control operation is constituted by a printed conductive pattern and various mounting parts. ing.

The battery 5 is a button battery such as a lithium battery, and has two battery terminals 4a and 4b whose both electrodes are provided on the printed board 4 so as to supply a driving voltage to the printed board 4. Have been touched.

That is, in FIG. 4, the first battery terminal 4a is formed of a conductive material having elasticity so as to project obliquely from the surface of the printed board 4 near the center of the battery housing position of the printed board 4. There is. As a result, when the battery 5 is in the storage position, the battery terminal 4a
Are pressed toward the surface of the printed circuit board 4 by the upper surface of the battery 5. Therefore, the battery terminal 4a is brought into contact with the upper surface of the battery 5 with a predetermined biasing force by the restoring force. Here, since the upper surface of the battery 5 is configured as, for example, a negative electrode, the first battery terminal 4a is connected to the negative electrode of the battery 5.
It will be electrically connected to the pole.

On the other hand, the second battery terminal 4b is formed so as to stand up from the surface of the printed circuit board 4 around the battery accommodation position of the printed circuit board 4, and a contact portion 4c extending in the horizontal direction is formed. It is made of an elastic conductive material so as to project obliquely toward the center of the battery storage position. As a result, when the battery 5 is in the storage position, the contact portion 4c of the battery terminal 4b is pressed outward by the side surface of the battery 5. Therefore, the contact portion 4c of the battery terminal 4b is brought into contact with the side surface of the battery 5 with a predetermined biasing force by the restoring force. Here, since the side surface of the battery 5 is configured as, for example, a + pole, the second battery terminal 4b is electrically connected to the + pole of the battery 5.

According to the remote control device 1 thus constructed, the negative pole of the battery 5 is connected to the first battery terminal 4a which contacts the upper surface of the battery, and the positive pole thereof contacts the side surface of the battery. By connecting to the second battery terminal 4b, power is supplied to the circuit formed on the printed circuit board 4. Therefore, by operating the operation button provided on the printed circuit board 4 from the outside of the case, a predetermined operation signal corresponding to the operated operation button is transmitted to the outside by an appropriate method such as infrared transmission or radio wave transmission. And the desired remote control operation can be performed.

[0009]

By the way, in the remote control device (electronic device) 1 having such a configuration, the battery 5 is used.
At the time of replacement, the lower case 3 is removed from the upper case 2 and the battery 5 is removed from the battery storage position on the printed circuit board 4, and a new battery 5 is attached to the first battery terminal 4a with the upper surface of the battery 5 being attached. The battery 5 is placed in the battery storage position while being in contact with the side surface of the battery 5 with the second battery terminal 4b. Then, the replacement of the battery 5 is completed by attaching the lower case 3 to the upper case 2.

However, when the lower case 3 is attached to the upper case 2, since the battery 5 is not fixed at the battery storage position, the battery 5 may be displaced from the battery storage position. Therefore, the battery 5 runs on the second battery terminal 4b, the lower case 3 cannot be attached to the upper case 2, and the battery 5 needs to be placed in the battery storage position again. There was a problem that the work was troublesome.

In view of the above points, an object of the present invention is to provide an electronic device in which the battery can be fixed at the battery housing position when the battery is replaced.

[0012]

The above object is to provide a case including an upper case and a lower case, a printed circuit board provided with a predetermined circuit on the lower surface of the upper case, and housed in the case. A button battery, and a first battery terminal provided on the printed circuit board so as to elastically contact the upper surface of the battery, and elastically contact the side surface of the battery. An electronic device, comprising: a second battery terminal disposed on a printed circuit board so as to be in contact with the printed circuit board, wherein the second battery terminal includes a protrusion extending along a lower surface of the battery. Is achieved by an electronic device.

[0013]

According to the above construction, the second battery terminal, which comes into contact with the side surface of the battery at the battery storage position, has the extension portion extending along the lower surface of the battery. The battery is inserted between the extension and the surface of the printed circuit board by pushing the battery into the battery storage position from the side opposite to the extension. As a result, the battery at the battery storage position is sandwiched between the printed circuit board surface and the extension portion, and can be fixedly held at the battery storage position. Then, from this state, by attaching the lower case to the upper case, the case is closed without the battery being displaced from the battery storage position.
