In the present embodiment, the negative electrode terminal 20b of the dry battery 20 is inserted toward the coil spring 7 disposed on the back side of the main body case portion 1, and the positive electrode terminal 20a of the dry battery 20 is pushed in on the battery cover 10 side to push the dry battery 20. , 20 are stored.

  The inner diameter of the coil spring 6 disposed in front of the opening 3 of the dry cell housing 2 is set slightly larger than the outer diameter of the dry cell 20, and, as described above, the center of the coil spring 6 and the center of the opening 13 are substantially the same. When the dry battery 20 is inserted from the opening 3, the dry battery 20 is housed through the coil spring 6 as shown in FIG. When the battery lid 10 is inserted into the opening 3 after inserting the dry batteries 20, the plate electrode 13 of the battery lid 10 and the coil spring 6 come into contact. When the battery cover 10 is pushed in against the urging force of the coil spring 6 as shown by an arrow (2) in FIG. 4B, the coil spring 6 is compressed and the battery The plate electrode 13 of the lid 10 and the positive electrode terminal 20a of the dry battery 20 in front contact with each other. When the battery cover 10 is further pushed in while the plate electrode 13 of the battery cover 10 and the positive electrode terminal 20a of the front dry battery 20 are in contact with each other, the negative electrode terminal 20b of the rear dry battery 20 contacts the coil spring 7. As shown by the arrow (4), the coil spring 7 is compressed, and the battery cover 10 is inserted into the opening 3. That is, by inserting the battery cover 10 into the opening 3, the positive electrode terminal 20 a of the front dry battery 20 is connected to the electronic circuit of the electronic board 5 via the plate electrode 13 of the battery cover 10 and the coil spring 6. The negative terminal 20 b of the back side dry battery 20 is connected to the electronic circuit of the electronic board 5 via the coil spring 7. As a result, the positive terminal 20a and the negative terminal 20b of the battery 20 are connected to the electronic circuit of the electronic substrate 5.

  Then, as shown by an arrow (5) in FIG. 4C, the battery cover 10 is rotated and the battery cover 10 is held in the opening 3 so that the inserted dry batteries 20, It is stored and held inside. Here, in the present embodiment, two dry batteries 20 are stored in series, but in another embodiment, one dry battery may be stored, or three or more dry batteries may be stored in series.

  Next, a procedure in which the battery lid 10 closes and holds the opening 3 of the dry battery storage section 2 will be described with reference to FIGS. FIG. 5 is a sectional view (side sectional view) taken along the line AA of FIG. 2 (A) of the peripheral portion of the opening 3, and FIG. 6 is a sectional view of FIG. 2 (A) of the peripheral portion of the opening 3. It is BB sectional drawing (top sectional drawing) shown.

  First, as shown in FIG. 5A, after the batteries 20 are inserted, the battery cover 10 is pushed into the opening 3 as shown by an arrow (1) against the urging force of the coil spring 6. As described above, the coil spring 6 is compressed in a state where the plate electrode 13 of the battery lid 10 and the coil spring 6 are in contact with each other (arrow (2) in FIG. 5B), and The plate electrode 13 of the battery lid 10 contacts.

  Here, the outer lid 11a of the battery lid 10 and the first opening 3b of the opening 3 are fitted to each other, and the rear end of the battery lid 10 composed of the inner lid 11e of the battery lid 10 and the guide plates 11g, 11g. The portion (hereinafter, “lock portion”) is adapted to fit with the regulating opening 3d of the opening 3, so that the battery cover 10 is pushed in the direction of the arrow (1) in FIG. As shown in FIG. 5B, the lock portion of the battery cover 10 goes deeper beyond the position of the rear surface 3e of the regulating opening 3d of the opening 3 as shown in FIG. Since the diameter of the second opening 3c is smaller than the diameter of the outer lid 11a of the battery lid 10, the locking portion of the battery lid 10 is located beyond the position of the rear surface 3e of the regulating opening 3d of the opening 3, and 10 is locked by the second opening 3c. In this state, since the lock portion of the battery cover 10 is located behind the rear surface 3e of the regulating opening 3d of the opening 3, the battery cover 10 is rotatable.

  Here, as shown by the arrow (1) in FIG. 6A, when the battery cover 10 is rotated, the guide of the lock portion of the battery cover 10 positioned in the vertical direction (the front-back direction with respect to the drawing). As shown in FIG. 6B, the plates 11g and 11g rotate and move in the horizontal direction (vertical direction with respect to the drawing). Since the diameter of the restricting opening 3d of the opening 3 in the horizontal direction (vertical direction in FIG. 6) is smaller than the diameter including the guide plates 11g, 11g of the lock portion, the guide plates 11g, 11g are formed on the rear surface 3e of the restricting opening 3d. In this position, the coil spring 6 is held by the biasing force. That is, the battery cover 10 is held with the opening 3 closed with the batteries 20, 20 stored in the battery storage section 2. Here, when the lock portion of the battery cover 10 is rotated to the horizontal position, the guide groove 11 d on the side surface of the outer cover portion 11 a of the battery cover 10 is rotated by the rotation restricting rib 3 a of the opening 3. , It is possible to prevent the battery cover 10 from rotating excessively.

  Further, since the outer diameter of the O-ring 12 is slightly larger than the inner diameter of the second opening 3c of the opening 3, when the opening 3 is closed by the battery lid 10, the O-ring 12 becomes the second opening 3c of the opening 3. And the opening 3 is sealed. As a result, the battery storage section 2 can be made waterproof. Note that the O-ring 12 is attached as in the present embodiment when waterproofness is required, but the O-ring 12 may be omitted when waterproofness is not required.

  Further, as shown in FIG. 6, since the positive electrode terminal side of the dry battery 20 is inserted into the coil spring 6, even if the battery cover 10 is rotated as described above, the movement of the coil spring 6 is suppressed. Thus, the dry batteries 20 can be stored in the dry battery storage section 2 in a state where the plate electrode 13 and the coil spring 6 are in stable contact with each other. Further, since the battery cover 10 is biased by the coil spring 6, when the batteries 20 are replaced, the battery cover 10 is detached by the biasing force of the coil spring 6, and the batteries 20 can be easily replaced. .

  Next, prevention of incorrect insertion of the batteries 20 will be described with reference to FIG. FIG. 7A is an enlarged view of the battery cover 10 when the batteries 20 and 20 are normally stored, and FIG. 7B is an enlarged view of the battery cover 10 when the batteries 20 and 20 are stored incorrectly.

  Since the heights of the two protrusions 11h and 11k on the rear surface of the battery lid main body 11 are set lower than the height of the positive electrode terminal 20a of the dry battery 20 to be stored, as shown in FIG. When the dry battery 20 is correctly inserted so that the positive electrode terminal 20a comes to the cover 10, the positive electrode terminal 20a of the dry battery 20 contacts the plate electrode plate 3 of the battery cover 10, but as shown in FIG. If the battery 20 is erroneously inserted so that the negative electrode terminal 20b comes toward the battery lid 10, the negative electrode terminal 20b of the dry battery 20 is connected to the plate electrode plate 3 of the battery lid 10 by the convex portions 11h and 11k. Do not touch. Therefore, even if the dry battery 20 is erroneously inserted, application of a reverse voltage to the electronic circuit of the electronic substrate 5 can be suppressed. That is, it is possible to prevent a problem that may occur due to incorrect insertion of the dry batteries 20, 20.

  Here, the dry cell storage section 2 is an example of a dry cell storage case, the dry cells 20 and 20 are an example of dry cells, the opening 3 is an example of an opening, the battery lid 10 is an example of a lid, and the coil spring 7 is an example.
