A microphone sound collecting hole 4 is also opened on the front side of the apparatus main body 1, and this portable communication apparatus is capable of reporting and talking via the wireless antenna 5.
[0004]
Further, when the front cover 6 disposed on the front side of the apparatus main body 1 is rotated and expanded toward the front side, the call button 7 for emergency notification disposed on the apparatus main body 1 and a wireless communication line are connected. A test button 8 for self-testing whether or not will appear, and these buttons 7 and 8 are operated as necessary.
[0005]
On the other hand, as shown in FIG. 5B, a battery storage chamber 10 for storing a battery 9 serving as a power source is formed on the back side of the apparatus main body 1 so as to penetrate the apparatus main body 1. The storage chamber 10 is closed by being covered with a storage chamber lid 11. In addition, as the battery 9 at this time, a dry battery which is a commercially available product is used.
[0006]
Further, as shown in FIG. 5 (c), in the battery storage chamber 10 which is closed by a removable storage chamber lid 11, there is a telescopic type which is in contact with each of the electrodes 9a and 9b of the battery 9 stored therein. The internal connection terminal 12 and the fixed internal connection terminal 13 are arranged opposite to each other after being in a state along the longitudinal direction L of the battery 9. In the battery storage chamber 10, two batteries 9 are generally stored in a parallel state in which the polarities are opposite to each other.
[0007]
Therefore, in this case, in the battery storage chamber 10, the first electrode 9 a of each battery 9, that is, the extendable internal connection terminal 12 that contacts the minus (−) electrode, and the second electrode 9 b of each battery 9, That is, each of the fixed internal connection terminals 13 that come into contact with the plus (+) electrode is also configured to be opposite in the longitudinal direction of the battery 9 and arranged for each inner wall surface of the battery storage chamber 10.

[Problems to be solved by the invention]
By the way, this type of mobile communication device is generally used for emergency communication to ensure the safety of users such as elderly people and physically handicapped persons, and is in an operable state. It is assumed that it is always carried by the user. Therefore, as a power source for the operation of this portable communication device, a system using a battery that is readily available in daily life, specifically, a normal battery such as a commercially available dry battery is adopted. Yes.
[0010]
On the other hand, in a widely used mobile phone or the like, a dedicated rechargeable battery is incorporated in the phone body, and is generally charged after being connected to a corresponding dedicated charging stand. In addition, rechargeable battery sets are widely sold to prepare for cases where charging of a rechargeable battery occurs at a destination. Therefore, it is conceivable to apply such a charging method to a mobile communication device, that is, a mobile communication device used for emergency communication.
[0011]
However, in the case of a charging-type mobile communication device, the fact that the user is basically a person who is prone to mental and physical abnormalities, it is connected to a dedicated charging stand and charging is in progress. After going out after forgetting, an emergency may occur while going out, and there is a risk that the function that the mobile communication device should originally perform may not be useful. Therefore, it is desirable to adopt a method using a normal battery instead of a charging method in a portable communication device that is required to be always worn by the user.
[0012]
If a rechargeable battery set is to be used at a destination, it is clear that it is easier to purchase a new battery and replace it. Under such circumstances, in mobile communication devices used for emergency communication or the like, a system that normally uses a battery is generally adopted, and the adoption of a charging system is actually being postponed.
[0013]
However, recently, as a power supply source in this type of portable communication device, it is desirable to use a power source other than a normal battery such as a dry battery, for example, another power source that can be expected to be a stable power source such as a cigar power source or an outlet power source of an automobile. The demand is growing. And even in this case, a portable communication device configured to be able to use a stable power source other than the battery while maintaining a basic structure capable of using the conventional battery is realized. It is strongly desired to do so.
[0014]
The portable communication device according to the present invention was created in response to such a demand, and a structure that enables long-term power supply from an external power supply while maintaining a conventional terminal structure for receiving power supply from a battery. The purpose is to provide a portable communication device.
[0015]
[Means for Solving the Problems]
The portable communication device according to the first aspect of the present invention includes a battery storage chamber formed in the device main body, and a storage chamber lid that is detachable and closes the battery storage chamber. The internal connection terminals that come into contact with each of the electrodes of the stored battery are arranged opposite to each other along the longitudinal direction of the battery. And this portable communication device is mounted on the inner surface side of the external power supply storage chamber lid instead of the normal storage chamber lid, and is stored in the battery instead of the battery. Auxiliary parts housed in the room.
[0018]
Furthermore, in the portable communication device according to the first aspect of the present invention, the first and second electrodes of the two batteries housed in the battery housing chamber with opposite polarities are in contact with each other. The first internal connection terminal and the second internal connection terminal are opposed to each other, and the auxiliary component is provided with first and second extension connection terminals that are in contact with the first and second internal connection terminals, respectively.
[0019]
The auxiliary component in this case is in contact with the first internal connection terminal where the first extension connection terminal contacts the first electrode of one of the batteries, and the second extension connection terminal mounted in contact with the second internal connection terminals each other in contact with the second electrode of the other battery is possible.
