As in the prior art, the lid (2) moves forward and is opened and locked in the retracted position. The upper surfaces of the lid (2) and the stopper (9) are located in substantially the same plane as the upper surface of the case body (1).
[0009]
2 (a) and 2 (b) are plan views of the lid (2), in which (a) shows a closed state and (b) shows an opened state. A bracket (5) is provided on the rear side of the recess (10), and a spring body (4) is provided below the lid (2) from the bracket (5). The spring body (4) is formed by bending a metal plate, and a protrusion (40) is formed upward at the tip of a flat plate (41) extending forward from the bracket (5). The spring body (4) may be formed of resin. The protrusion (91) protrudes forward from the stopper (9), and the lid (2) is closed with the lid (2) closed, and the stopper (9) is rotated as described later. prevent. A recess (20) is formed at the rear end of the lid (2). With the lid (2) open, the recess (20) is fitted to the spring body (4) as described later. To keep the lid (2) open.
[0010]
FIG. 3 is an exploded perspective view of the lid (2) and the case main body (1), and FIG. 4 is a perspective view of the lid (2) attached to the case main body (1) in an opened state. An opening (11) is provided on the bottom surface of the recess (10), and the battery (3) is accommodated in the opening (11). For example, the battery (3) is provided with terminals (30) and (30) on the front surface, and the back surface of the lid (2) is not provided with a terminal plate. The lid (2) is provided with a pivot (21) at the base end and a claw (22) at the tip. A long hole (50) extending in the front-rear direction is formed in the side surface of the bracket (5), the pivot (21) is fitted into the long hole (50), and the lid (2) moves back and forth.
The stopper (9) is configured by urging a claw piece (90) in contact with the upper end of the battery (3) toward the transition path of the battery (3) with a torsion spring (not shown). By energizing the claw piece (90) with a torsion spring to constitute the stopper (9), even if the claw piece (90) is pushed by the side surface of the battery (3) and kept rotating outwardly, The force for urging the nail piece (90) does not change with time. That is, if the stopper (9) is in contact with the battery (3) by the elastic force of the resin as in the prior art, the claw piece (90) is pushed by the side surface of the battery (3) and rotated outward. If it continues for a long time, the elastic urging force of the stopper (9) deteriorates, but this possibility does not occur in this example.
At the tip of the claw piece (90), a slope (92) is formed in contact with the bottom surface of the battery (3) when the battery (3) is inserted. When the battery is inserted, the bottom surface of the battery (3) has a slope (92). Press to rotate the claw piece (90) outward once. When the battery (3) is fitted in the opening (11), the claw piece (90) is restored and contacts the upper surface of the battery (3), thereby preventing the battery (3) from being inadvertently escaped.

The lid (2) can be opened at a position advanced along the long hole (50). To close the lid (2), the lid (2) is rotated counterclockwise around the pivot (21) from the state shown in FIG. 5 (a). As shown in FIG. 5 (b), from the state in which the engaging piece (12) and the claw portion (22) face each other, the user places the finger on the finger hook portion (25) and moves the lid (2) backward. As a result, the engaging piece (12) and the claw portion (22) are engaged, and the lid (2) is locked. The lid (2) covers the projection (91) of the claw piece (90), and the claw piece (90) does not rotate carelessly. The lid (2) also covers the slope (92) of the claw piece (90).
[0012]
(Click feeling when operating the lid)
6A, 6B, and 6C are side views of FIG. 4 viewed from the A direction. In the state where the lid (2) is closed and retracted, the pivot (21) is located behind the protrusion (40) of the spring (4) as shown in FIG. 6 (a). By the protrusion (40), the lid (2) is prevented from being carelessly advanced from the position shown in FIG. 6 (a).
When the user puts his finger on the finger rest (25) (see FIG. 1) and advances the lid (2) against the elastic biasing force of the protrusion (40), the protrusion (40) is pivoted ( 21), the spring body (4) is once bent downward about the base end. When the pivot (21) passes through the protrusion (40), the spring body (4) is elastically restored to the state shown in FIG. 6 (b). Thereby, careless retreat of the lid (2) is restricted, and the lid (2) does not move even if an impact is applied to the case body (1). When the pivot (21) passes through the protrusion (40), the pivot (21) pushes down the protrusion (40), and the moving load of the lid (2) increases once and then decreases. The user's finger feels a click, and it can be seen that the lid (2) is unlocked. That is, inadvertent movement of the lid (2) is restricted by the protrusion (40), and a click feeling when the lid (2) is locked and unlocked is transmitted to the user.
[0013]
From the forward position shown in FIG. 6 (b), the lid (2) is opened by rotating it clockwise by hand. As shown in FIG. 6 (c), the recess (20) of the lid (2) fits into the protrusion (40) to prevent the lid (2) from rotating too much. The spring body (4) bends downward, and the cover body (2) is held in the open completion state shown in FIG. 6 (c) by the elastic biasing force of the spring body (4).
To close the lid (2), the reverse operation is performed. The lid (2) is rotated counterclockwise against the biasing force of the spring body (4) from the state shown in FIG. 6 (c), returned to the state shown in FIG. When 2) is retracted against the protrusion (40), the state shown in FIG. 6 (a) is reached.
As a result, the lid (2) is held at the forward position, the backward position, and the opening completion position, and a click feeling is transmitted to the user when the lid (2) moves back and forth, and the lid (2 ) Is locked and unlocked.
[0014]
6 (a), 6 (b), and 6 (c), the pivot (21) is provided above the spring body (4). However, as shown in FIGS. 7 (a), (b), and (c), the pivot (21) may be provided below the spring body (4). In this case, the protrusion (40) has its bulge directed downward, and a protrusion (23) is formed at the rear end of the lid (2). In the state where the lid (2) is retracted, the pivot (21) is located behind the protrusion (40) as shown in FIG. 7 (a).
When the lid (2) is advanced, the protrusion (40) is pushed by the pivot (21), and the spring body (4) is once bent upward about the base end. When the pivot (21) passes through the protrusion (40), the spring body (4) is elastically restored to the state shown in FIG. 7 (b). When the lid (2) is pivoted and opened by hand, as shown in FIG. 7 (c), the projecting piece (23) of the lid (2) is fitted into the projecting portion (40), The lid (2) is prevented from rotating too much. The spring body (4) bends downward and holds the lid (2) at the position shown in FIG. 7 (c) by the elastic biasing force of the spring body (4).
7 (a), (b), and (c), the lid (2) is held at the forward position, the backward position, and the opening completion position, and the lid (2) is moved back and forth. Click feeling is transmitted to the user.
[0015]
In this example, since the upper surface of the stopper (9) is positioned substantially in the same plane as the upper surface of the lid (2), as shown in FIG. The height of the case main body (1) can be reduced as compared with the conventional configuration located below.
Further, since the stopper (9) is covered with the lid (2) retracted in the closed state, the stopper (9) is not inadvertently detached from the battery (3) due to an external impact or the like. There is no problem that the battery (3) is loose within (1).
