[Embodiment of device]

 Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings.

[Embodiment Example of First Invention] FIGS. 1 and 2 are views for explaining a structure of a battery holder according to an example of an embodiment of the invention according to the present invention, in which a part is cut away. Is shown. The following description will be made by taking as an example a case where the battery holders are configured so that they can be housed in such a manner that the polarities of the batteries are opposite to each other so that two batteries are connected in series. However, the present invention is not limited to the above example, and two batteries may be connected in parallel. Furthermore, it goes without saying that a plurality of batteries may be arranged in two rows.

In FIGS. 1 and 2, reference numeral 10 denotes a front wall portion having a battery insertion opening having a diameter slightly larger than the shape of one battery in the vertical direction. The battery insertion opening of the front wall portion 10 corresponds to one battery. A circular battery insertion port (opening) that can be inserted and removed is provided, and this battery insertion port has a substantially circular shape that closes the battery insertion port and has a screw thread on the outer periphery. A female screw with which 20 is screwed is implanted. Reference numerals 11 and 13 denote side wall portions that are arranged in a storage width for two batteries so that the two batteries 51 and 52 can be arranged and stored.

Reference numeral 12 is a battery holding portion in which a contact conductor pattern 45 that comes into contact with the electrode of the battery 52 is arranged at a predetermined position on the surface, and the battery 52 is housed in the side wall portion 11 side to hold one side of the battery. . 14 is the back wall. The back wall 14 does not necessarily have to be provided and can be omitted.

Reference numerals 15 and 16 denote an upper wall portion and a lower wall portion that sandwich the batteries 51 and 52. Reference numeral 20 denotes a lid member on the outer peripheral portion of which a screw 21 which is screwed into a female screw of a battery insertion port provided on the front wall portion 10 is arranged, and at least a tip end portion of which is formed of a conductive material. It is configured to be electrically connected to the conductive pattern 42 which comes into contact with the electrode of 51 and leads electric power from the battery to the outside through the female screw portion of the front wall portion.

In the above description, the lid member 20 and the battery insertion opening are screwed together and fixed. This is to prevent the lid member from being fixed to the battery holder securely and easily. In addition, this configuration also makes it easy to form a liquid-tight configuration.

For example, taking a medical machine such as a Holter electrocardiograph as an example, it is necessary to keep the medical machine clean, and a third party (including a person who uses the apparatus) can easily perform the operation. It is necessary to make it impossible to change the performance of, and to include the power supply carelessly.

In such a case, if the battery holder structure according to the embodiment of the present invention is used, the battery holder portion can be easily made into a liquid-tight structure, and sterilization of the device can be performed very easily to clean the device. It will be easy to keep Further, since the battery cannot be easily removed, it is possible to prevent accidental removal of the battery.

However, the present invention is not limited to the above examples, and when the need for a liquid-tight structure or the like is low, the lid member can be fixed to the battery insertion opening after the battery is stored. The structure does not matter. For example, it may be locked by rotating the lid member by a predetermined angle, or may be locked by pushing the lid member by a predetermined amount or more.

Reference numeral 30 denotes a rotary member having a configuration peculiar to the embodiment of the present invention, and reference numeral 35 denotes a battery suspended between the upper wall portion 15 and the lower wall portion 16 at a substantially central position of the batteries 51, 52. The shaft 40 is a spring which is an elastic member locked at a position of the rotating member 30 facing the battery insertion port.

The rotating member 30 is configured to be rotatable around the shaft 35 as a fulcrum, and the first battery 52 is inserted from the battery insertion port, and the battery is stored in the battery holding portion 12 part. At this time, the rotating member 30 rotates to raise the portion 37 in FIG. 1 upward, so that the battery 52 can be easily positioned and stored in the position shown in FIG.

Next, the next battery 51 is inserted from the battery insertion port. As the battery 51 is inserted, the tip of the battery 51 contacts the spring 40. Then, when the battery 51 is further inserted into the inside against the elastic force of the spring 40, the rotating member 30 rotates, and the portion 37 (contact portion with the battery 52) in FIG. It will be in pressure contact with the electrode of. Then, by closing the battery insertion port with the lid member 20, all the electrodes of the storage batteries 51, 52 are pressed into contact with each other by the elastic force of one spring 40 to hold the battery.

It should be noted that at least the battery 51 contact portion of the spring 40, which is the electrode contact position of the rotating member 30, and the contact portion 37 with the battery 52 are electrically connected by a conductive pattern. Both electrodes of 51 and the battery 52 are electrically connected, and the batteries are connected in series in the illustrated state.

As described above, according to the embodiment of the present invention, the one electrode of the battery is locked by the rotating member 30, and only one spring 40 arranged on the rotating member 30 is provided. Each electrode of the battery can be pressed into contact with the conductive pattern by the elastic force, and each battery can be reliably stored in the holder with a simple structure.

In addition, the space for accommodating the battery need only be a space corresponding to the circumference of the battery, and the space for the accommodating part of the battery can be minimized. For this reason, it is easy to arrange each part of the device having the battery holder, and even in the case where the device is used by connecting to another device or device, for example, the battery can be replaced while being attached to the device. Easy to do.

Furthermore, since the space for inserting the battery is small, it is possible to easily form a liquid-tight structure. Further, in the above description of the embodiment of the second invention, the rotating member is described. The case where the shaft 35 is rotatably attached to the shaft 35 provided between the upper wall portion 15 and the lower wall portion 16 has been described as an example. However, the present invention is not limited to the above example, and for example, rather than providing a shaft between the upper wall portion 15 and the lower wall portion 16 in the embodiment of the first invention described above, the inner wall 1 It is also possible that a substantially central portion of the front surface of 4 is extended downward, a shaft is provided between the extended portion and the lower wall portion 16, and the rotating member is rotatably fixed to the shaft. Alternatively, a substantially central portion of the front surface of the inner wall 14 extends downward, and a substantially central portion of the rear surface also extends downward. A shaft is provided between the extending portions of the front surface and the rear surface, and the rotating member is attached to the shaft. May be pivotally fixed.

With the above-described configuration, it is not necessary to integrally form the upper wall portion 15 or the upper wall portion 15 and the lower wall portion 16 and the shaft. For example, the rear wall 14 is provided with the rotating member and the shaft. Since the upper wall portion 15 or the upper wall portion 15 can be positioned and fixed after mounting, the assembly can be facilitated. A second example of the embodiment of the idea according to the present invention configured as above will be described below with reference to FIG. In the following description, the same components as those in FIGS. 1 and 2 described above are denoted by the same reference numerals and detailed description thereof will be omitted.

In FIG. 3, the lid member 20 is configured to project from the front wall portion 10, and can be directly rotated by hand and screwed to be closed and closed without using an employee or the like. .

Further, the shaft for rotatably stopping the rotating member 130 is not provided between the upper wall portion 15 and the lower wall portion 16, but the front wall or the rear wall of the inner wall 14 is substantially downwardly centered. A shaft is provided in the extending portion 145, and the rotating member 130 is rotatably fixed to the shaft.

With the above configuration, in addition to the function and effect of the embodiment of the first invention described above, the upper wall portion or the upper wall portion and the lower wall portion and the shaft are integrally formed. It is not necessary, and for example, the upper wall portion 15 or the upper wall portion 15 can be positioned and fixed after the turning member and the shaft are attached to the inner wall 14, and the assembling can be facilitated.

[Embodiment of Third Invention] In the above description, an example in which the spring 40, which is an elastic member, is provided at the position opposite to the battery insertion port of the rotating member 130 has been described. However, the present invention is not limited to the above example, and the spring may be provided at the position of the battery housing 12 as long as it is in contact with the electrode of the battery or the battery housing of the rotating member. They may be provided at opposite positions. Further, even if the spring is fixed to the lid member 20, it is possible to similarly obtain a good pressure contact state with each electrode portion of the battery.

Further, the elastic member is not limited to the spring member at all, and may be a sponge member made of a conductive material, for example.

Hereinafter, as a third embodiment of the present invention, an embodiment of the third invention of the present invention, in which a spring is fixed to a lid member among the above-mentioned respective parts, will be described with reference to FIG. And FIG. 5 will be described.

In FIGS. 4 and 5, the same components as those of the embodiment of the second invention shown in FIG. 3 described above are denoted by the same reference numerals and detailed description thereof will be omitted.

4 and 5, the basic structure is the same as the structure shown in FIG. 3 in the above-described second embodiment, but in the third embodiment, the rotating member is sprinkled. Is not formed, and the rotating member 230 is electrically connected by a conductive pattern or a conductive foil plate formed of a conductive material between the electrode contact positions of both batteries when the battery is stored. It is only formed and has a substantially common surface.

As the lid member 220, a spring 225 is arranged at the tip end portion that abuts the battery electrode, and the vicinity of the tip end portion of the spring 225 is used as a storage battery electrode (a positive electrode of the battery in the example of FIG. 5). The battery is pushed in the direction of the rotating member 230 by pressing the battery and screwing it into the battery housing hole provided in the front wall to close the battery. As a result, the electrode abutting portion of the rotating member 230 facing the lid member is pushed up by the elastic force of the spring 225 to rotate, and both electrodes of the battery between the electrode holding portion 12 and the rotating member 230 are pressed together. In this state, the electrodes of all the batteries are brought into pressure contact with each other by the elastic force of one spring 225, so that it is possible to provide a battery holder in a good battery accommodation state.

With the above-described structure, it is possible to achieve the same effects as the effects achieved by the embodiment of the second invention described above. Further, it is not necessary to fix the spring to the rotating member, which facilitates the manufacturing of the rotating member. Further, it is easier to attach the spring to the lid member, and the workability as a whole is improved.

[Effect of device]

 As described above, according to the present invention, the one electrode of the battery is locked by the rotating member, and is slightly arranged on the rotating member or on the other battery electrode contact portion. The elastic force of one elastic member can be distributed to each electrode portion of the battery and pressed against each other, and each battery can be reliably stored in the holder with a simple structure.

Also, a small space is sufficient for the battery storage portion, and the space for the battery storage portion can be minimized. Therefore, it is easy to arrange each part of the device that has the battery holder.For example, in the case where it is used by connecting to another device or device, the battery can be replaced while being attached to the device. Can be done easily.

Further, the battery insertion portion need only be provided with a circular opening for inserting and removing one battery, and this portion can be closed by screwing to easily form a liquid-tight structure. In addition, it is possible to maintain a compact and extremely good storage condition in a small space.
