It has dry battery support parts 14b and 15b. The battery receiving member 15 has a guide rod 15c protruding in the A2 direction, and the guide rod 15c passes through a hole in the partition wall 17 of the electronic device housing 10 in a state where the coil spring 16 is fitted. . The battery receiving member 15 is urged in the A1 direction by a coil spring 16.

A single dry cell 20 is supported by a single dry cell support portion 14a of a dry cell receiving member 14 and a single dry cell support portion 15a of a dry cell receiving member 15, and has a negative electrode 20a.
Is pressed against the negative electrode terminal plate 12 and the positive electrode terminal plate 13
Is pressed against the positive electrode 20b, and is housed in the dry cell housing space 11 with the lid 19 covering the dry battery housing space 11.

[0004] The new single-cell battery 20 is replaced with the new single-cell battery 20.
When replacing the battery with 0, first, the operation of removing the old single battery 20 from the battery housing space 11 is performed as follows. Open the lid 19. With a finger of one hand, the battery receiving member 15 is slightly pressed and held in the direction A2 to hold the single battery 20 free.
As shown by a two-dot chain line in (B), the finger 25 of the other hand is inserted into the dry cell housing space portion 11 and is brought into contact with the upper end portion 20c on the positive electrode 20b side of the dry cell 20 to pull up the dry cell 20. To do.

After the positive electrode 20b of the single battery 20 is lifted, the finger holding down the battery receiving member 15 is released. The work of installing a new single battery 20 is
Perform as follows. By pushing the dry cell receiving member 15 in the X2 direction with the finger of one hand, the distance between the dry cell receiving member 14 and the dry cell receiving member 15 is increased, and the dry cell receiving member 15 is pressed in this state.

[0007]

As described above, the work for removing and installing the dry battery requires both hands,
Since the operation was performed while holding the dry cell receiving member 15 with one hand, the operation was difficult. In addition, the single-cell battery 20 and the single-cell
Since the fitting position of the dry battery receiving members 14 and 15 is different from that of the dry battery 21, there is a possibility that the operation may be erroneous.

Accordingly, an object of the present invention is to provide a dry cell housing structure that solves the above problems and an electronic device having the same.

[0009]

According to a first aspect of the present invention, there is provided a dry cell accommodating space for accommodating a dry cell, and an upper end of the dry cell in the dry cell accommodating space with the upper surface of the dry cell accommodating space closed. Presser, a lid that is opened when the dry battery is removed, a fixed electrode terminal member and a spring-biased electrode terminal member that are provided facing each other in the dry battery housing space portion, and the above-described dry battery housing space portion. On the side of the fixed electrode terminal member, an unfolded protrusion that is provided to protrude into the dry battery accommodating space portion in a ragged manner, a push-up plate provided in the dry battery accommodating space portion, and a push-up plate that is pushed up. When the lid is opened in a state where the dry battery is housed in the dry battery housing space and the lid is closed, the dry battery moves the fixed electrode terminal member side toward the fixed electrode terminal member. Protruding The electrode terminal member, which is sandwiched and held between the portion and the push-up plate and is biased by spring, is brought into a state of protruding from the dry cell housing space by the push-up plate. .

Since the fixed electrode terminal member side of the dry battery is sandwiched and held between the protruding portion and the push-up plate, the spring-biased electrode terminal member side of the dry battery protrudes from the dry cell housing space.

The positive electrode 20b side of the dry battery 20 is pushed up, the single dry battery 20 becomes oblique, and the upper end portion 20c protrudes from the dry battery housing space 45.

The single battery 20 is held on the side of the negative electrode 20a, and does not fall out of the dry battery housing space 45 and is safe. After the single dry battery 20 is mounted in the remaining dry cell housing space 45 as described above, the lid 35 is pushed and slid in the Y1 direction and locked at the final position to close the dry battery housing space 45.

By sliding the lid 35, the rib 35b pushes the portion of the single battery 20 protruding from the battery housing space 45 from the inclined portion 35c, and the positive electrode 20b side of the single battery 20 is placed in the battery housing space 45. Pushed into. Thus, as shown in FIGS. 7B and 7C,
The single battery 20 has its upper end pressed by the rib 35b and is completely housed in the battery housing space 45.
The negative electrode 20a is pressed against the negative electrode terminal member 42 while the positive electrode 20b is pressed against the positive electrode terminal member 43.

(2) Removal of the single battery 20 As shown in FIG. 8A, the cover 35 is pulled out in the Y2 direction to open the battery housing space 45. When the lid 35 is pulled out, the single-cell battery 20 is released from being pressed by the rib 35b, and the negative electrode 20a side is mainly pressed by the spring force of the first coil spring 48, as shown in FIG. The positive electrode 20b side is held between the protruding portion 40d and the push-up plate 41 and held in the Z1 direction by a portion of the push-up plate 41 near the end in the Y1 direction by the spring force of the second coil spring 49. It is pushed up and rises, and the positive electrode 20b side protrudes from the dry cell housing space portion 45 in an oblique direction, and a finger-hookable portion 2 to which a finger can be hung.
0 g is formed.

Although the single battery 20 can be easily removed, the single battery 20 is safe because it does not fall out of the battery housing space 45 and fall. As shown in FIG. 8B, the operator places the finger 25 of one hand on the finger-holdable portion 20 g and pulls it in the direction indicated by the arrow G. As a result, the single-cell battery 20 becomes the battery shown in FIG.
As shown in (C), the user is lifted up, and the pinch holding by the compressed protrusion 40d and the push-up plate 41 is released.

The operator grasps the single battery 20 with the remaining fingers of the finger 25 on the finger restable portion 20 g and takes it out. The remaining single battery 20 mounted in the battery housing space 45 is also taken out as described above. In addition, the dry cell housing structure portion 37 having the above-described configuration is capable of mounting the AA battery 21 or the AA battery 22.
