Moreover, the number of assembly steps can be reduced by reducing the number of components. Furthermore, since the protrusion (22) is formed on the back surface of the lid (2), the appearance of the appearance is not impaired.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
(First embodiment)
1 (a) and 1 (b) are perspective views of a digital camera which is an embodiment of the apparatus according to the present invention turned upside down. FIG. 1 (a) shows a state in which the lid (2) is closed. ) Shows the state in which the lid (2) is opened. The lid (2) is provided so as to be slidable back and forth on the cabinet (1). The claw piece (23) is fitted to the tip of the lid (2), and the claw piece (23) is fitted to the cabinet (1). The fitting hole (10) is opened. The claw piece (23) and the fitting hole (10) constitute a locking mechanism for the lid (2). When the closed lid (2) is pushed in the direction B in FIG. 1 (a) and pivoted upward about the pivot (4) located at the base end of the lid (2), the lock is released and the lid is released. The body (2) opens and the battery storage chamber (11) in the cabinet (1) is exposed.
The pivot (4) is fixed to the cabinet (1), and a torsion spring (3) for rotating the lid (2) in the opening direction is fitted to the pivot (4). The pivot (4) is made of metal in view of rigidity, and the lid (2) is made of synthetic resin.

  2 (a) is a cross-sectional view of the lid (2) of FIG. 1 (a) taken along the line AA and viewed from the direction of the arrow, and FIG. 2 (b) is a cross-sectional view of FIG. 2 (a). The state which advanced the cover (2) of this is shown. An arm piece (20) is provided at the base end of the lid (2), and a long hole (21) extending in the front-rear direction is formed in the arm piece (20). The lid (2) is guided to slide back and forth in the long hole (21), and the pivot (4) and the torsion spring (3) do not slide. When the lid (2) is slid forward from the closed state shown in FIG. 2 (a), the claw piece (23) is separated from the fitting hole (10) as shown in FIG. (2) can be opened.

3 is an exploded perspective view of FIG. 1B, and FIG. 4 is a cross-sectional view of FIG. 3 taken along the line C-C and viewed from the direction of the arrow. The arm pieces (20) and (20) are provided on both sides of the lid (2) in the width direction, and a protrusion (22) is formed on the back surface of the lid (2) between the arm pieces (20) and (20). Is done. The torsion spring (3) includes a winding diameter portion (31) fitted to the pivot (4), leg pieces (30) and (30) protruding from both longitudinal sides of the winding diameter portion (31), and a winding diameter portion (31 ) Is integrally formed with a receiving piece (32) projecting in the opposite direction from the leg piece (30) from the longitudinal central portion. The receiving piece (32) is in contact with the upper surface of the cabinet (1).
A rounded contact (33) is formed at the tip of the leg piece (30), and the corresponding contact (33) is applied to the back surface of the lid (2) by the urging force of the leg piece (30). Press contact. As will be described later, when the lid (2) moves back and forth, the contact (33) passes through the protrusion (22), so that the user who slides the lid (2) gets a click feeling.
The torsion spring (3) is not limited to a configuration in which the two leg pieces (30) and (30) are integrated. For example, as described later in FIG. 6, the two torsion springs (3) and (3) are separately provided. It may be provided. Moreover, since the opening load of the lid (2) is determined by the opening angle between the leg pieces (30), (30) of the torsion spring (3) and the receiving piece (32), the opening load of the lid (2) is arbitrary. Can be set.

(When sliding the lid)
5 (a) is a cross-sectional view showing a state in which the lid (2) is retracted in a closed state, (b) is a cross-sectional view showing a state in which the lid (2) is advanced in a closed state, and (c) is a cross-sectional view. It is sectional drawing which shows the state which the cover body (2) advanced forward opened. The torsion spring (3) urges the lid (2) backward until the contact (33) passes through the protrusion (22) when the lid (2) moves forward from the retracted state.
When the user advances the lid (2) by hand from the state shown in FIG. 5 (a) to the state shown in FIG. 5 (b), the protrusion (22) comes into contact with the contact (33). The leg piece (30) is elastically deformed against the urging force of the leg piece (30). When the lid (2) is further slid, the contact (33) gets over the protrusion (22). That is, since the elastic force becomes stronger and then weakens, the user feels a click feeling, and it can be seen that the nail piece (23) is detached from the fitting hole (10) and the lid (2) can be opened. . When the lid (2) is unlocked and the user releases his / her hand from the lid (2), the lid (2) is opened by the biasing force of the torsion spring (3) as shown in FIG. 5 (c).

In this example, the torsion spring (3) and the lid (2) provide a click feeling when the lid (2) is slid. Accordingly, in order to obtain a click feeling as compared with the conventional configuration, the leaf spring (6) and the screws for fastening the leaf spring (6) to the cabinet (1) are unnecessary, and the number of components can be reduced. it can. Moreover, the number of assembly steps can be reduced by reducing the number of components. Furthermore, since the protrusion (22) is formed on the back surface of the lid (2), the appearance of the appearance is not impaired.

(Second embodiment)
With the above configuration, a click feeling was obtained when the lid (2) was slid back and forth with the torsion spring (3). However, there may be a case where a satisfactory click feeling cannot be obtained only with the torsion spring (3), and there is a strong possibility that the torsion spring (3) is particularly small. Therefore, the following ideas have been devised.
FIG. 6 is an exploded perspective view showing another embodiment of the lid (2), and the lid (2) is more proximal than the protrusion (22) between the pair of arm pieces (20) and (20). An intermediate piece (24) is provided on the side, and the leg piece (30) of the torsion spring (3) is fitted into the gap between the arm piece (20) and the intermediate piece (24). Since the intermediate piece (24) is provided, the torsion spring (3) has a shape in which the winding diameter portion (31) extends long along the width direction of the lid (2) as shown in FIG. Can not. Accordingly, two torsion springs (3) and (3) that fit into the gap between the arm piece (20) and the intermediate piece (24) are provided. In FIG. 6, two torsion springs (3) are shown, but any one may be used.

In the long hole (21) formed in the arm piece (20), as shown in FIG. 7, a protrusion (26) protrudes downward. As described above, since the lid (2) is made of synthetic resin, the protrusion (26) is also made of synthetic resin. Further, since the pivot (4) is made of metal, the projection (26) can be elastically deformed in contact with the projection (26). As described above, when the lid (2) moves back and forth, the pivot (4) passes through the projection (26) while being elastically deformed by contacting the projection (26). At this time, the user who moves the lid (2) back and forth gets a click feeling.
Further, instead of forming the protrusion (26) in the long hole (21) or forming the protrusion (26) in the long hole (21), as shown in FIG. 8, the side surface of the intermediate piece (24) In addition, the same click feeling can be obtained by opening a through hole (25) extending in the front-rear direction and passing through the pivot (4), and providing a projection (26) in the through hole (25). 7 and 8, the protrusion (26) protrudes downward, but may protrude upward. The protrusion (26) may be bent and deformed in contact with the pivot (4), and is not limited to being formed in the long hole (21) or the through hole (25). For example, the protrusion (26) may be provided on the side surface of the arm piece (20).
Furthermore, as shown in FIG. 10, in addition to the structure in which the projection (26) is formed in the long hole (21) or the through hole (25), the click feeling when the lid (2) is moved back and forth by the torsion spring (3). You may implement the structure which obtains.
