Also, cover moves carelessly open position, or the cover can be prevented from returning to the inadvertent unloading preparation position, it is possible to improve the convenience when loading and unloading operations of the battery.

  As shown in FIG. 1, a strobe light emitting unit 4 and a lens barrel 5 are provided on the front surface of a main body (device main body) 3 of a digital camera (portable electronic device) 2. A lens 6 and a lens barrier 7 are incorporated. Further, a finder 8 is provided on the front surface of the main body 3, and a release button 9 is provided on the upper surface of the main body 3.

  A cover 10 is provided on the bottom surface of the main body 3. The cover 10 opens and closes an opening 24 (see FIG. 2) for loading and unloading the battery pack 12. The cover 10 has a lock position (position shown in FIG. 3) that is locked to the main body 3 in a state where the opening 24 is closed, and a lock release position that is slid from the lock position and unlocked from the main body 3 (see FIG. 3). (Position shown in FIG. 4). Further, after moving to the unlocking position, the cover 10 can be rotated to an opening position (a position shown in FIG. 6) that opens the opening 24 and allows the battery pack 12 to be loaded and unloaded. The battery pack 12 includes a contact 13. When the battery pack 12 is loaded, the contact 13 is electrically connected to the contact in the main body 3, and power is supplied to the main body 3. Thereby, the main body 3 can be driven.

  As shown in FIG. 2, a battery loading device 20 is provided in the main body 3. The battery loading device 20 includes a base member 21, a cover 10, and a plate-shaped click spring (rotation restricting means) 22.

  The base member 21 is formed in a box shape, and a loading chamber 23 for the battery pack 12 is formed in a part thereof. An opening 24 is formed in a part of the bottom surface of the base member 21, and the opening 24 communicates with the loading chamber 23. The battery pack 12 is loaded into the loading chamber 23 from the opening 24. When the cover 10 is in the locked position, the opening 24 is closed by the cover 10.

  A pair of grooves 25 facing each other are formed on the side wall of the base member 21. The groove 25 is formed linearly and extends horizontally from the side of the loading chamber 23 toward the loading chamber 23.

  A shaft (rotating shaft) 26 of the cover 10 is inserted into the groove 25. On the base side of the cover 10, a bearing portion 10 a that protrudes in the direction in which the battery pack 12 is loaded (the direction of arrow B in the figure) is formed. The upper end of the bearing portion 10a is formed in an arc shape. The bearing portion 10a is formed with insertion holes 10b penetrating through both side surfaces thereof. The shaft 26 is inserted into the insertion hole 10 b inside the base member 21, and both ends thereof are supported by the grooves 25. As a result, the cover 10 rotates about the shaft 26 and slides along the groove 25.

  A cylindrical rib 27 is provided on the bottom surface of the base member 21 at a position farther from the loading chamber 23 than the groove 25. The base side of the click spring 22 is attached to the upper end surface of the rib 27 with a screw 28. When the click spring 22 is attached to the rib 27, the tip side protrudes toward the loading chamber 23. A claw 22 a is provided at the tip of the click spring 22 so as to protrude in the direction of taking out the battery pack 12. The nail | claw 22a is formed in the substantially square shape, and consists of the 1st slope 22b and the 2nd slope 22c which inclined in the mutually opposite direction toward the front end side. The first slope 22b is formed on the root side, and the second slope 22c is formed on the tip side.

  The bearing portion 10a of the cover 10 is formed with a locking hole (first locking portion) 10c on the rear end surface. The locking hole 10c is formed in substantially the same shape as the claw 22a. When the claw 22a is fitted into the locking hole 10c, the cover 10 and the click spring 22 are elastically engaged. Thereby, the cover 10 is restricted from rotating in the opening direction at an extraction preparation position (position shown in FIG. 5) in the middle of rotating from the unlocked position toward the opened position. A locking surface (second locking portion) 10d is formed below the locking hole 10c. The locking surface 10d is formed by chamfering the rear end surface of the bearing portion 10a. The locking surface 10d is pressed by the second inclined surface 22c of the click spring 22 when the cover 10 is located at the open position. Thereby, the rotation of the cover 10 from the open position to the take-out preparation position is restricted.

  The cover 10 is bent into a substantially L shape so that the tip side protrudes toward the inner surface side. The folded portion serves as the battery holding portion 10e. The battery holding part 10e receives the battery pack 12 that falls when the cover 10 is positioned at the preparation preparation position. Further, the cover 10 is formed with a locking claw 10 f that protrudes from the battery holding portion 10 e toward the shaft 26 of the cover 10. A locking hole 21 a is formed in a portion of the side wall of the base member 21 that faces the locking claw 10 f. In a state where the cover 10 is positioned at the lock position, the locking claw 10f is locked in the locking hole 21a. Thereby, the cover 10 is held in the locked position.

  A spring 29 is attached to the inner surface of the cover 10, and the loaded battery pack 12 is urged by the spring 29 in the loading direction. Thereby, when the battery pack 12 is loaded, the contact 13 and the contact in the main body 3 are surely brought into contact with each other.

  Next, the effect | action by the said structure is demonstrated using FIGS. 4 to 6, illustration of the spring 29 is omitted in order to prevent the drawings from becoming complicated.

  As shown in FIG. 3, when the battery pack 12 is loaded on the main body 3, the cover 10 is positioned at the lock position. In this state, the cover 10 closes the opening 24 of the base member 21, and the shaft 26 is positioned closer to the root of the click spring 22 than the claw 22 a.

  As shown in FIG. 4, in order to take out the battery pack 12 from the main body 3, first, the cover 10 is slid from the lock position toward the lock release position. When the cover 10 is slid, the bearing portion 10a pushes up the claw 22a and then moves to the tip side of the click spring 22 from the claw 22a. As a result, the locking between the locking hole 21a and the locking claw 10f is released, and the cover 10 moves to the unlocking position. At this time, it is possible to identify that the cover 10 has moved from the locked position to the unlocked position by the feel (click feeling) when the bearing portion 10a pushes up the claw 22a.

  As shown in FIG. 5, after moving the cover 10 to the unlock position, the cover 10 is rotated in the opening direction (the battery pack 12 removal direction side). When the cover 10 is rotated, the cover 10 moves to the take-out preparation position. Thereby, the claw 22a is elastically engaged with the locking hole 10c, and the battery holding portion 10e of the cover 10 enters the take-out path of the battery pack 12. When the cover 10 moves to the take-out preparation position, the battery pack 12 falls from the loading chamber 23 by its own weight. At this time, the battery pack 12 is received by the battery holding portion 10e and prevented from falling. Thereby, it is possible to prevent the battery pack 12 from being accidentally dropped when the cover 10 is opened. Further, it can be identified that the cover 10 has moved from the unlocked position to the take-out preparation position by the feel when the claw 22a is elastically engaged with the locking hole 10c.

  As shown in FIG. 6, when the cover 10 is rotated in the opening direction from the take-out preparation position, the elastic engagement between the claw 22a and the locking hole 10c is released. When the cover 10 is further rotated from this state, the battery holding portion 10e is retracted from the removal path of the battery pack 12, and the cover 10 is moved to the open position. Thereby, the battery pack 12 can be taken out from the loading chamber 23. At this time, the locking surface 10d of the cover 10 is pressed by the second inclined surface 22c of the claw 22a, and the cover 10 is elastically held in the open position.

  When the battery pack 12 is to be loaded, after the battery pack 12 is loaded into the loading chamber 23, the cover 10 is rotated so as to pass through the open position → the removal preparation position → the lock release position, so that the lock release position is shifted to the lock position. The cover 10 is slid and operated. Thereby, the locking claw 10f is locked in the locking hole 21a, and the cover 10 is held in the locked position.

  Next, a second embodiment will be described with reference to FIGS. In addition, about the member which has the same function as the said 1st Embodiment, description is abbreviate | omitted using the same code | symbol. As shown in FIG. 7, in the second embodiment, a cover 40 having a configuration different from that of the cover 10 used in the first embodiment is used.

  Further, the cover 40 is different from the cover 10 in that the locking hole 10c of the cover 10 is not provided. The cover 40 has the same bearing portion 40a as the bearing portion 10a, the same locking claw 40b as the locking claw 10f, and the same locking surface 40c as the locking surface 10d. It is part of the configuration. A groove (guide means) 41 through which the shaft 26 is inserted extends from the side of the loading chamber 23 to below the battery pack 12.

  As shown in FIG. 7, when the battery pack 12 is loaded in the main body 3, the cover 40 is positioned at the lock position. In this state, the cover 40 closes the opening 24 of the base member 21, and the shaft 26 is positioned closer to the base of the click spring 22 than the claw 22a.

  As shown in FIG. 8, in order to take out the battery pack 12 from the main body 3, first, the cover 40 is slid from the lock position toward the lock release position. When the cover 40 is slid, the elastic engagement between the locking hole 21a and the locking claw 40b is released, and after the bearing portion 40a pushes up the claw 22a of the click spring 22, the cover 40 moves to the unlock position.

  As shown in FIG. 9, after the cover 40 is moved to the unlocking position and the cover 40 is further slid along the groove 41, the shaft 26 and the bearing portion 40 a enter the take-out path of the battery pack 12. As a result, the cover 40 moves to the take-out preparation position. When the cover 40 is rotated in the opening direction (the battery pack 12 removal direction side) at the removal preparation position, the locking surface 40 c is pressed by the second inclined surface 22 c of the click spring 22. As a result, the movement of the bearing portion 40a is restricted, and the movement of the shaft 26 is restricted so that the bearing portion 40a is not removed from the take-out path of the battery pack 12. When the cover 40 moves to the removal preparation position, the battery pack 12 falls from the loading chamber 23 under its own weight. However, since the bearing portion 40a is positioned on the removal path of the battery pack 12, the battery pack 12 is moved by the bearing portion 40a. The fall is blocked. Thereby, it is possible to prevent the battery pack 12 from being accidentally dropped when the cover 40 is opened.

  As shown in FIG. 10, after the cover 40 is taken out and rotated to the preparation preparation position, the cover 26 resists the urging force of the click spring 22 so that the shaft 26 moves to the base side of the click spring 22 from the claw 22a. 40 is pressed. Accordingly, the cover 40 is returned to the original position where the bearing portion 40a is removed from the take-out path of the battery pack 12. When the cover 40 moves to the open position, the battery pack 12 can be removed from the loading chamber 23. In the open position, the first inclined surface 22b of the click spring 22 restricts the movement of the bearing portion 40a, thereby restricting the movement of the shaft 26 so that the bearing portion 40a does not return to the extraction preparation position. This prevents the cover 40 from being inadvertently moved to the take-out preparation position.

  Next, a third embodiment will be described with reference to FIGS. In addition, about the member which has the same function as the said 1st Embodiment, description is abbreviate | omitted using the same code | symbol. As shown in FIG. 11, in the third embodiment, the same cover 40 as in the second embodiment is used. The groove 43 through which the shaft 26 is inserted is formed in a straight line. The groove 43 extends to the side of the loading chamber 23.

  As shown in FIG. 11, when the battery pack 12 is loaded in the main body 3, the cover 40 is positioned at the lock position. In this state, the cover 40 closes the opening 24 of the base member 21, and the shaft 26 is positioned closer to the base of the click spring 22 than the claw 22a.

  As shown in FIG. 12, in order to take out the battery pack 12 from the main body 3, first, the cover 40 is slid from the lock position toward the lock release position. When the cover 40 is slid, the bearing portion 40a pushes up the claw 22a of the click spring 22, and then the shaft 26 moves to the tip side of the click spring 22 from the claw 22a. Thereby, the latching of the main body 3 and the latching claw 40b is released, and the cover 40 moves to the unlocking position.

  As shown in FIG. 13, after the cover 40 is moved to the unlocking position, the cover 40 is rotated in the opening direction (the battery pack 12 removal direction side). As a result, the cover 40 moves to the take-out preparation position. When the cover 40 is rotated to the take-out preparation position, the battery pack 12 falls from the loading chamber 23 by its own weight. At this time, the locking surface 40 c of the bearing portion 40 a is pressed against the second inclined surface 22 c of the click spring 22, and the bearing portion 40 a is biased toward the battery pack 12. In this state, a frictional force is generated between the bearing portion 40a and the battery pack 12, so that the battery pack 12 is prevented from falling. Thereby, it is possible to prevent the battery pack 12 from being accidentally dropped when the cover 40 is opened.

  As shown in FIG. 14, when the cover 40 is rotated in the opening direction from the take-out preparation position, the pressing on the locking surface 40c by the second inclined surface 22c of the click spring 22 is released. Thereby, the cover 40 moves to the open position, and the battery pack 12 can be taken out from the loading chamber 23. In the open position, the bearing portion 40a is pressed by the second inclined surface 22c, and the cover 10 is elastically held in the open position.

  Next, a fourth embodiment will be described with reference to FIGS. In addition, about the member which has the same function as the said 1st Embodiment, description is abbreviate | omitted using the same code | symbol. As shown in FIG. 15, in the fourth embodiment, a cover 45 having a configuration different from that of the cover 10 used in the first embodiment is used. A substantially trapezoidal side wall 45 a is provided at both ends of the cover 45. As shown in FIG. 16, each side wall 45a is provided with a convex portion 45b on the surface facing each other. The battery pack 12 has a recess 12a on the side wall to which the protrusion 45b is engaged. Two recesses 12 a are provided along the sliding direction of the cover 45. The cover 45 is a portion having the same configuration as the cover 10 in that a bearing portion 45c that is the same as the bearing portion 10a and a locking claw 45d that is the same as the locking claw 10f are provided. The groove 46 through which the shaft 26 is inserted is formed in a straight line. The groove 46 extends to the side of the loading chamber 23.

  As shown in FIGS. 15 and 16, when the battery pack 12 is loaded in the main body 3, the cover 45 is located at the lock position (position shown in FIG. 15). In this state, the cover 45 closes the opening 24 of the base member 21, and the shaft 26 thereof is positioned closer to the root of the click spring 22 than the claw 22 a. Further, the convex portion 45 b of the cover 45 is engaged with the concave portion 12 a on the shaft side of the battery pack 12.

  As shown in FIGS. 17 and 18, in order to remove the battery pack 12 from the main body 3, first, the cover 45 is slid from the lock position toward the lock release position. When the cover 45 is slid, the convex portion 45 b of the cover 45 is locked to the concave portion 12 a on the front end side of the battery pack 12. Thereby, the latching of the main body 3 and the latching claws 45d is released, and the cover 45 moves to the unlocking position (position shown in FIG. 17).

  As shown in FIG. 19, after moving the cover 45 to the unlock position, the cover 45 is rotated in the opening direction (the battery pack 12 removal direction side). Thereby, the cover 45 moves to the take-out preparation position. At the take-out preparation position, the battery pack 12 is pulled out of the loading chamber 23 by the engagement between the convex portion 45 b of the cover 45 and the concave portion 12 a of the battery pack 12. At this time, since the convex portion 45b of the cover 45 is engaged with the concave portion 12a of the battery pack 12, it is possible to prevent the battery pack 12 from being accidentally dropped.

  As shown in FIG. 20, when the cover 45 is rotated in the opening direction from the take-out preparation position, the engagement between the convex portion 45b of the cover 45 and the concave portion 12a of the battery pack 12 is released, and the cover 45 is rotated to the open position.

As will be described in detail later, the battery holding portion 53a receives the battery pack 12 that falls when the cover main body 53 is located at the take-out preparation position. Further, the cover main body 53 is formed with a locking claw 53 b that protrudes from the battery holding portion 53 a to the shaft side of the cover 52. A locking hole 51 a is formed in a portion of the side wall of the base member 51 that faces the locking claw 53 b. When the cover main body 53 is located at the lock position, the locking claw 53b is locked in the locking hole 51a. Thereby, the cover main body 53 is held in the locked position.

  A pair of rails 53 c are formed at both ends of the cover body 53. Each of the rails 53c is formed in a substantially L shape, and the tips of the rails 53c face each other. A click spring 54 is inserted into the gap formed by forming the rail 53c. Thereby, the cover main body 53 is slidably held by the click spring 54.

  The click spring 54 is provided with a claw 54a formed by cutting out the periphery thereof. The claw 54a is formed by bending the click spring 54 into a substantially square shape so as to protrude in the battery pack 12 removal direction (arrow B direction in the figure).

  Further, three locking holes 53d to 53f are formed at the center of the upper surface of the cover main body 53. The locking holes 53d to 53f are formed in substantially the same shape as the claw 54a, and the claw 54a can be locked. The locking holes 53d to 53f are arranged along the longitudinal direction of the cover main body 53, that is, along the sliding direction of the cover main body 53 (the axial side of the click spring 54 is the locking hole 53d, and the middle is the locking hole. 53e, the front end side of the click spring 54 is a locking hole 53f). When the click spring 54 is inserted into the gap of the rail 53c, the claw 54a is locked in the locking holes 53d to 53f. Thereby, the cover main body 53 and the click spring 54 are united.

  A spring 29 (see FIG. 22) is attached to the inner surface of the cover 10, and the loaded battery pack 12 is urged by the spring 29 in the loading direction. Thereby, when the battery pack 12 is loaded, the contact 13 and the contact in the main body 3 are surely brought into contact with each other.

  Next, the effect | action by the said structure is demonstrated using FIGS. 22-25. 23 to 25, the spring 29 is not shown in order to prevent the drawings from becoming complicated.

  As shown in FIG. 22, in a state where the battery pack 12 is loaded in the main body 3, the cover 52 is located at the lock position (position shown in FIG. 22). In this state, the cover 52 closes the opening 56 of the base member 51, and the claw 54a is locked in the locking hole 53c.
