A battery cover 30 covering the opening 12 of the battery chamber 10 has a guide protrusion 30a on the back surface which is inserted into an elongated hole (not shown) formed in the plus conductive terminal 28 so as to avoid the plus terminal 27 of the battery 8. When the guide projection 30a is guided to move by the elongated hole of the positive conductive terminal 28, the battery cover 30 moves in the direction intersecting with the protruding direction of the positive terminal 27 as indicated by a two-dot chain line indicated by reference numeral C. It can slide freely. The guide projection 30a also prevents the battery cover 30 from being detached from the positive conductive terminal 28 above.

When the battery cover 30 is located at the closed position indicated by the solid line in FIG. 2C, the battery cover 30 is formed at the outer end of the battery cover 30 corresponding to the outer end of the opening 12 of the battery chamber 10. The engagement projection 32 is engaged with the engagement recess 34 formed at the outer end of the opening 12, and the battery lid 30 holds the engagement of the engagement projection 32 with the engagement recess 34. As described above, the inner end is urged inward by the urging means 36 disposed in the vicinity of the battery chamber 10 inside the main body of the above-described apparatus using a battery.

When the battery cover 30 is closed, the engagement protrusion 3
2 is engaged with the engagement recess 34 of the opening 12 of the battery chamber 10, so that the negative terminal 40 of the battery 8 in the battery chamber 10 is
And is held in the closed position against the elastic force of the negative conductive terminal 42 for the purpose.

The battery cover 30 is opposed to the urging force of the urging means 36 from the closed position shown by the solid line in FIG. 2C and the two points indicated by reference numeral C in FIG. As shown by the dashed line, the guide projection 3 is slid to a position where the engagement of the engagement projection 32 with the engagement recess 34 is released, and further raised upward.
With the positive conductive terminal 28 connected by Oa, it is rotated upward to a position shown by a two-dot chain line indicated by reference numeral D around the rotation center axis 29 to open the opening 12 of the battery chamber 10.

[0011]

[Problems to be Solved by the Invention] In recent years, as devices that use batteries, such as small AV equipment, have been further miniaturized, devices using only one small dry battery, such as AAA, have appeared. The miniaturization of the battery lid of the device is also progressing. Here, it is difficult to use an engaging means using an elastic protruding piece as shown in FIGS. 2A and 2B for a battery lid due to a problem of strength, and FIG. The use of the biasing means for the battery lid is an obstacle to further miniaturization of the device using the battery.

The present invention has been made under the above circumstances, and an object of the present invention is to prevent the battery cover from being opened even when the above-described device using a battery is carried in a bag or a pocket and carried around. By providing a battery storage device that is simple and does not hinder the miniaturization of the external dimensions of the above-described device using a battery, and that can clearly confirm the disposition and movement of the battery cover to and from the closed position. is there.

[0013]

In order to achieve the above object, a battery storage device according to the present invention has a conductive terminal which is electrically connected to a positive terminal of a battery stored in a battery chamber. A battery lid is provided, which is slidable in a direction intersecting with the projecting direction of the plus terminal, and the battery cover is over the same level as the projecting end face of the plus terminal in the direction opposite to the projecting direction of the plus terminal. It is characterized in that it has a projection that moves from one side of the plus terminal to the other side over the projecting end face of the plus terminal as the battery cover slides.

[0014]

When the battery cover is slid from the open position to the closed position, the protrusion of the battery cover rides over the projecting end surface of the positive terminal of the battery in the battery compartment, and the battery cover is locked in the closed position.

Therefore, the same members are denoted by the same reference numerals, detailed description thereof will be omitted, and only different structures will be described in detail. To prevent the drawing from becoming complicated,
In FIG. 1A, the battery cover 30 is illustrated as being transparent for convenience. Details are omitted.

In this embodiment, the urging means 36 for the battery cover 30 is not used, and instead, a click protrusion protruding from the back surface of the battery cover 30 toward the plus terminal 27 of the battery 8 in the battery compartment 10 is used. 50 are formed.

The click projection 50 is inserted into an elongated hole 28a formed in the positive conductive terminal 28 on the back side of the battery cover 30 and extending in the sliding direction of the battery cover 30, so that the battery cover 30 is exposed as shown by a solid line. When the engagement projection 32 at the end is disposed in the closed position in which the engagement projection 32 is engaged with the engagement recess 34 at the outer end of the opening 12 of the battery chamber 10, as shown particularly well in FIG. It is arranged closer to the peripheral surface of the plus terminal 27 on the inner side of the above-described device using the battery than the plus terminal 27 of the battery 8. The protruding end face of the click projection 50
As shown particularly well in FIG. 1B, the battery 8 protrudes slightly inside the battery chamber 10 from the level of the protruding end face of the plus terminal 27 of the battery 8 and faces the peripheral surface of the plus terminal 27 of the battery 8. The protruding end of the click projection 50 is curved or inclined. The elongated hole 28 a of the positive conductive terminal 28 faces the protruding end surface of the positive terminal 27 of the battery 8 and extends in the sliding direction of the battery cover 30.

The battery cover 30 is guided by the movement of the click projection 50 into the elongated hole 28a of the positive conductive terminal 28, or a guide member (not shown) provided on the battery cover 30 itself is connected to the side edge of the positive conductive terminal 28. By being engaged and guided for movement, the battery cover 30 is slidable in a direction intersecting the protruding direction of the plus terminal 27 as indicated by a two-dot chain line indicated by reference numeral C. Provision, or other suitable means, prevents upward disengagement from positive conductive terminal 28.

As a step before rotating the battery cover 30 to an open position indicated by a two-dot chain line indicated by a reference numeral D in FIG. 1B, the engagement of the outer end of the opening 12 of the battery chamber 10 is performed. In order to release the engagement projection 32 of the outer end of the battery cover 30 with the concave portion 34, the battery cover 30 is moved from the closed position shown by a solid line in FIG. ), While sliding to the position indicated by the two-dot chain line indicated by reference symbol C,
