Description of the Invention: Technical Field The present invention relates to a cover opening and closing mechanism in which a cover is rotatably supported by a casing to rotate between a closed position and an open position. 'In the closed position, a slot formed in the housing is covered, and in the open position the slot is exposed. [Prior Art] In recent years, a portable small-sized electronic device such as an electronic camera has been popularized. In such an electronic device, a battery of a rechargeable battery or the like is used as a power source and is loaded in a casing of the device. Therefore, the electronic device is provided with a cover for inserting and removing the battery from the device casing. As a mechanism for opening and closing the cover, a known mechanism such as a cover for closing a groove formed in a casing is slid between a locking position and a release position at the lock The cover covers the groove and is held by the case so as not to be opened when the position is fixed, and the cover is released from the case in the release position (for example, see Japanese Patent Laid-Open Publication No. 06-897 10 , 1 0-3 89 3, 2003 - 1 4284 1 and 2004-79543). The cover is rotated to an open position via the release position to expose the slot. The cover opening and closing mechanism of the above publication is provided with a sliding mechanism for projecting the cover from one of the outer sides of the case, and a locking mechanism for preventing rotation of the cover. In this cover opening and closing mechanism, when the cover is slid to protrude to the outside of the case, the lock of the lock mechanism is released to allow the cover to be opened. However, in the cover opening and closing mechanism 200807128 explained in the above publication, since the cover is slid to protrude to the outside of the case, the cover opening lines are formed on the required two surfaces. Therefore, there arises a problem that the constituent parts require complicated processing and the cost increases. Further, the locking mechanism is disposed at a corner of the casing to cause other problems such as impact and the like, which are easily damaged. SUMMARY OF THE INVENTION In view of the above, a main object of the present invention is to open and close a device having a structure for damage due to prevention of dropping or the like. In order to achieve the above and other objects, in accordance with the present invention, the closing device includes a locking mechanism, a latching portion and a rotating cover that are held in a locked position, the locking mechanism blocks the open position, The position is formed in the mouth of one of the surfaces of the shell. The latch retains the cover in the locked position and in a locked release position. When the cover is held in the locked position, the cover is attached to the inner side of the side of the surface. When the cover is held in the lock release position Φ The cover is away from the inside of the side. The rotating mechanism allows the cover to be rotated to the open position near one end of a sliding side thereof when the cover is held in the lock. In a preferred embodiment, the end of the cover defines one of the front ends when the cover is slidably moved to the lock release position. The shaft includes a shaft and a pair of elongated holes. The shaft is disposed on the front of the cover and perpendicular to the sliding direction of the cover. The elongated holes are the front end of the cover and the other of the casing, and the ends of the shaft cooperate with the elongated holes in the sliding direction. In the case of the shell, the cover is opened and constructed by the cover provided by the drop. The release position is directed to the cover, the lock rotation mechanism end and the housing are formed to extend in the middle when the transition to the first stroke is slidably adjacent to the adjacent position. 200807128 w Preferably, the lid opening and closing device further includes an engaging claw portion and an elastic member. The engaging claw portion is disposed adjacent to a position of the mouth portion and a side of the shaft to hold the article loaded in the mouth portion. The elastic member holds the engaging claw portion and is bendable in one direction from which the mouth is withdrawn toward the shaft. Preferably, the opening and closing device further comprises a torsion spring and a sliding surface. The shaft is embedded in the torsion spring and is biased by the spring against the cover toward the open position. One end of the torsion spring is in contact with an inner surface Φ of the cover and the other end is in contact with the outer casing. On the sliding surface, each end of the torsion spring slides thereon when the cover slides between the locked position and the lock release position. The sliding surface is angled to widen the spacing of the cover and the engaging portion toward the shaft. Preferably, the locking mechanism includes a projection, an engagement projection and a plurality of contact surfaces. The protruding portion is formed on an inner side of the cover. The engaging projection is formed on the case, and the engaging projection holds the projection when the cover is held in the locking position. When the cover is moved to the lock release position φ, the engagement projection is disengaged from the projection. The contact surfaces are formed on the projection and the engagement projection. The contact surfaces are in contact with each other when the cover is moved from the open position to the locked release position in which the mouth is covered. The cover is relatively close to the locked position and not to the lock release position. The contact surfaces are inclined such that they are inclined from the cover toward the axis. Preferably, the opening and closing device further includes a catching projection and a stopping member. The stop projection is formed on one of the cover and an inner side of the case. The stop member is disposed on the other of the cover and the inner side of the case. When the cover is held in the locked position, the stopping member holds the 掣 200807128 * the projection to apply a resistance to a sliding operation of the cover. The retaining member is biased from the stop position in the open position to apply pressure to the cover. [Embodiment] An electronic camera 10 shown in Fig. 1 includes different imaging mechanisms in a camera body 11 having a built-in hexahedral shell.

The cover 3 1 is opened and closed when a battery and a memory card are embedded in the body 1 1 and removed from the camera body 1 1 . The cover opening and closing mechanism of the present invention is performed by the cover 31 and the ground. And slidably holding the retainer 32 of the cover 31. As shown in the figure, the container unit 30 includes a shell body 40 and a lid 31 which are parallelepiped. The unit body 40 includes a row of the battery 41 that overcomes the portion and is directed toward a parallel shutter of the camera lens 112 to change the shutter button. The camera has an image and 19 (see 2nd [30] (see 30 by the display unit 30 in the figure, the camera is closed. Used to rotate a unit as shown in Figure 3: and the memory 200807128 • Card 44 ( See Fig. 3) The battery 41 is a power source for driving the various parts of the camera body 11. The memory card 44 is a recording medium for storing image data. The aforementioned holder 32 is formed. a concave portion at the bottom of the unit body 40. As shown in Figs. 4A and 4B, a space having a size larger than that of the cover 31 is formed so that the cover 31 can be configured to be held therein. The inside of the device 32 is slid in the direction indicated by the arrow A. The cover 31 can be held by the holder 32 in a locked position (shown in #4A) and a released position (shown in Figure 4B). In the locked position, the cover 31 is adjacent to an inner wall 32a and the rotation of the cover 31 is prevented by a locking mechanism which will be described later. In the released position, the cover 31 Adjacent to an inner wall 32b, the locking of the securing mechanism is released. The cover 31 is adjacent to The inner side of the lower surface of the camera body 11 is slid. When the cover 31 has been slid from the locked position to the release position, the cover 31 is surrounded by a rotating mechanism in a sliding direction. A φ end of the cover 31 is rotated. As will be described later, the rotating mechanism is composed of a rotating shaft 5 1 and an elongated hole 52. The rotating mechanism will be described below. The rotation shaft 51. Further, the holder 32 is provided with two elongated holes 52' formed in the side wall adjacent to the inner wall 32b and extending in the sliding direction of the cover 31 (indicated by the arrow A). Both ends of the rotating shaft 51 are engaged with the two elongated holes 52. The cover 31 is held by the holder 32 so as to be slidable in the direction of the arrow A and made available in the direction of the arrow B. Rotating. A battery slot 43 and a card slot 45 are formed in a surface 200807128w face 32c of the holder 32. When the cover 31 is closed, the surface 32c faces an inner surface 31a. A mouth of a battery compartment 42 for the unit 41 of the battery unit 41. The card To embed one of the mouths of the memory card 44. At the same time, an engaging claw portion is placed on one side of the rotating shaft 51 to be adjacent to the battery slot 4, and the battery 41 is dropped from the battery chamber. The engaging claw portion 46 complements a head portion of the leaf spring 47 and can be indicated by an arrow A in the sliding direction of the cover.) • When the cover 31 is held in the locked position (displayed in the 4A. Blocked by the locking mechanism. As will be described later, the cymbal includes a projection, an engagement projection and a retaining opening for the projection. The locking mechanism will be described below. The three projections 54 to 5 6 is formed around the cover 31. When the 31 is held in the locked position (shown in Fig. 4A), the hair 54 is embedded in the engagement formed in the inner wall 32a of the holder 32 and is thereby held to prevent the rotation of the cover 31. When the cover φ is moved to the release position (shown in FIG. 4B), the protrusion engaging opening 61 is withdrawn and detached therefrom so that the cover 31 becomes becomes the cover 31 when the cover 31 is held. Position (shown in Fig. 4A) the projection 55 is held by the engaging projection, which engages an inner wall 32d of the retainer to prevent rotation of the cover 31. When moved to the release position ( When shown in Fig. 4B), the protrusion is withdrawn from the engaging projection and is detached therefrom to rotate the cover 3 1. As shown in Figs. 5A to 5C, the retainer 3 2 The Feng's cover 3 1 is embedded in the 4 5 to be equipped with 46 to prevent [fixed to move (by the middle), one of the "fixing mechanism" when the cover is closed, the opening 6 1 31 is moved 54 from the When it is rotatable. In the middle of the cover 31, the cover portion 5 5 becomes visible to the surface -10- 200807128 • 32c is provided with an engaging projection 62 and a position formed at one of the projections 56 Opening 63. When the cover 31 is held in the locked position (shown in FIG. 4A), the protrusion 56 is held by one of the engaging projections 62 as shown in FIG. 5A to block the cover 31. Turn. When the cover 31 is moved to the release position (shown in FIG. 4B), the projection 56 is withdrawn to one side of the opening 63 and protrudes from the engagement as shown in FIG. 5B. The portion 62 is disengaged such that the cover 31 becomes rotatable. As shown in Fig. 3, the projection 56 is disposed closer to one of the levers (rotation shaft 51) than the projections Φ 5 4 and 55. When the rotating shaft 51 is held in a position closer to the locking position than the releasing position (as shown in FIG. 5C) within the range of the elongated hole 52, the protruding portion 56 and the engaging claw portion 62. Contact at the beginning of the rotation of the cover 31 in a closing direction. The contact surfaces 5 6 a and 6 2 a for contacting each other form a slope, so that when the cover 31 is biased in the closing direction, a force acts in the direction of the arrow C with respect to the cover 31. In other words, the contact φ surface 62a of the engaging projection 62 is inclined so as to be inclined from the cover 31 toward the rotating shaft 51, and the contact surface 56a of the protruding portion 56 is inclined so as to start contacting each other' The contact surface 62a is parallel. Therefore, when the cover 31 is closed in the state as shown in Fig. 5C, the force acts in the direction of the arrow c to move the cover 31 to the release position shown in Fig. 5B. The rotating shaft 51 described above is embedded in a torsion spring 53. One end 53a of the twisting spring 53 abuts against the inner surface 31a of the cover 31, and the other end 5 3 b thereof abuts against the opposite surface 3 2 c. With the torsion spring 5 3, the cover 31 is pressed to face the open position shown in Fig. 3. -11- 200807128 • In view of this, after sliding the cover 31 from the locking position (shown in Figure 4A) to the release position (shown in Figure 4B), the cover 31 is not visible One of the positions in FIG. 6A is moved to one of the stomachs shown in FIG. 6B and then the cover 31 is pressed by the torsion spring .53 to a force shown in a position in FIG. 6C. Turn. At this time, when the rotating shaft 51 moves between the positions shown in Figs. 6A and 16B with respect to the elongated hole 52, the other end 53b of the torsion spring 53 slides on the opposite surface 32c. The opposite end surface 32c of the other end 53b is formed with a slope 32e which is inclined to be inclined from the cover 31 toward the inner wall 32b. The tip end of the other end 53b is bent into an arc shape as shown in Fig. 3 to prevent the other end 53b from being caught by the slope 32e when the other end 53b slides on the slope 32e. If the other end 53b of the torsion spring 53 is flat on the surface to be slid, when the cover 31 is rotated in the closing direction, a force acts to move the cover 31 to the locked position (shown in the fourth In the picture A). In this case, the user has to perform two operations, one for performing the closing of the cover 31 and the other for performing the movement of the cover 31 to the release position (shown in Figure 4B). However, in this case, the other end 53b is formed in the region to be slid as the inclined surface 32e as explained above, and when the cover 31 is rotated in the closing direction, the inclined surface 32e prevents the force from acting The cover 31 is moved to the locked position (shown in FIG. 4A) as shown in FIG. 6C. Therefore, the cover 31 is moved to the position shown in Fig. 6B without the cover 31 being moved toward the locking position. Next, a stop mechanism will explain the following. As will be described later, the stop structure is composed of a stop projection 57 and a sheet 66 which is regarded as a stop member 掣 -12· 200807128 *. An opening 65 is formed in the opposing surface 3 2 c. The stop sheet 6 6 is configured to protrude through the opening 65 to the side of the opposing surface 32c. The quenching plate 66 is a leaf spring. One of the curved portions 66a is curved toward the cover side. A curved portion 66a is formed at a front end of the damper sheet 66 as shown in Figs. 7A to 7C. Further, a rear end of the damper sheet 66 is bent to be fixed to a rear portion of the opposite surface 32c at a position closer to the rotation shaft 51 than the opening 65. Further, the stop projections 57 are formed on the inner surface 3 1 a of the cover 3]. When the cover 31 is held in the locked position (as shown in Fig. 4A), the stop projection 57 is located adjacent to a front end of the curved portion 66a as shown in Fig. 7A. At this time, the stopping portion 57 is held by the bent portion 66a. In view of this, a resistance is generated when the cover 31 is slid toward the release position (shown in Fig. 4B). After the sliding operation overcomes the resistance, the stop sheet 66 is elastically deformed and the curved portion 66a is moved upward (toward the opening 6 5) to release the holding state. And φ, as shown in Fig. 7B, the curved portion 66a is in contact with the upper portion of the stop projection 57 (located at the side of the opening 65). At this time, the cover 31 is urged by a restoring force of the damper sheet 66 to rotate toward the open position shown in Fig. 7C. Next, an operation of the container unit 3 having the above structure will be explained as follows. When a user attempts to load the battery 41 and the memory card 44 into the camera body 11, the cover 31 of the container unit 30 is opened. Further, when the user tries to remove the battery 4 1 and the memory card 4 from the camera body 1 1 , the cover 31 is opened. -13- 200807128 • When the cover 31 is held in the locked position (shown in Fig. 4A), the locking mechanism described above prevents the cover 31 from rotating. Therefore, the cover 3 1 is slid from the locked position (shown in Fig. 4A) to the release position (shown in Fig. 4B). Further, when the cover 31 is held in the locked position (shown in FIG. 4A), the squeezing projection 57 is bent as shown by the seventh drawing. 6 6 a keep. The cover 31 is slid by overcoming the resistance of the damper sheet 66. When the cover 31 is moved to the release position (display Φ in Fig. 4B), the squeezing sheet 66 is elastically deformed and the curved portion 66a is as shown in Fig. 7B. 57 moves upward (toward the opening 6 5 ). When the curved portion 6 6 a is moved upward, the restoring force of the damper sheet 6 6 forces the cover 31 to face the open position (shown in Fig. 7C). At this time, the cover 31 is also urged toward the open position by the torsion spring 53. The cover 31 is rotated by the urging force of the damper plate 66 and the torsion spring 53 to the open position as shown in Fig. 3 to expose the battery case 43 and the card slot 45. After that, the battery 41 and the memory card 44 are loaded or removed. Thereby, when the battery 41 is loaded, the engaging claw portion 46 is moved to the outside of the battery groove 43. Similarly, when the battery 41 is removed, the engaging claw portion 46 is moved to the outside of the battery can 43. Incidentally, the engaging claw portion 46 is disposed such that the cover 31 is moved to one side (on the rotating shaft 51) when opened. Since the operation direction is general, good operability can be achieved. When the cover 31 is closed, the force acting in the closing direction is applied to the cover 31 held in the open position (shown in Figs. 6C and 7C). At this time, the end 53b of the torsion spring 53 is brought into contact with the slope 3 2e to prevent the force from acting toward the locking position (shown in Fig. 4A). Therefore, only by applying the force to the cover 3 1 due to the direction of the arrow C, the cover 31 is moved to the release position (shown in Fig. 4B). As a result, it is not necessary to apply the force to move the cover 31 toward the release position, and the cover 31 can be moved to the release position in one step of operation. When the force in the closing direction is applied to the cover 31 such that the rotational axis 51 is in a state where φ is closer to the locked position (shown in FIG. 5A) than to the released position (shown in FIG. 5B) At this time, when the protruding portion 56 and the engaging projection portion 6 2 are in contact with each other, the force of the closing direction is further applied to the cover 31. Thereafter, the force is applied to the cover 3 1 in the direction of the arrow C to move the cover 31 to the release position. In this way, it is possible to move the cover 31 to the release position only by applying the force in the closing direction. Thereafter, the 盍3 1 is moved from the release position (not shown in Fig. 4B) to the lock position (shown in Fig. 4A). And then, the locking mechanism of the holder 32 holds the cover 31 to prevent the rotation of the cover 31. As described above, when the cover 31 is closed, the 盍 31 may be moved to the release position (shown in Fig. 4B) only by applying the force to the cover 31 in the closing direction. Therefore, the operability of closing the cover 31 is improved. Further, as described above, the cover 31 is moved within the range of the holder 32 disposed inside the lower surface of the camera body 11. As a result, the cover 31 moves inside the side wall surface adjacent to the lower surface, so that the locking mechanism of the cover 3 i is prevented from being disposed at a corner of the camera body 11. In the case of -15-200807128, even if an impact is generated at the corner of the camera body 11 due to dropping or the like, the locking mechanism can be prevented from being damaged. Meanwhile, in the case where the cover 31 is slid to the outside of the side wall surface, a cover opening line is formed on the surfaces of the lower and side walls. However, in the case where the cover 31 moves inside the side wall surface adjacent to the lower surface as described in the present invention, it is sufficient to form the cover opening line only on the lower surface. Therefore, a cover member for constituting the camera body 11 can be easily processed and the production cost can be reduced. In addition, the appearance has also improved. In the above embodiment, the rotating mechanism is composed of a rotating shaft attached to the cover and an elongated hole formed in the retainer. However, this rotating mechanism is not unique. An elongated hole to which the shaft can be attached to the retainer and engaged with the shaft can be formed in the cover to constitute another rotating mechanism. In this case, the end of the torsion spring slides on the inner surface of the cover as the cover moves between the locked position and the released position. In view of this, it is preferable that the sliding surface is formed as a slope. In the above embodiment, the stopping mechanism is composed of the damper sheet attached to the holder, and the damper projection formed on the inner surface of the cover. However, this stop mechanism is not the only one. The quenching sheet may be attached to an inner surface of the lid and the quilling projection may be formed on the holder. In the above embodiment, the container portion of the container unit is disposed on the lower surface of the camera body. However, this is not the only one. The container portion is formed integrally with the lower surface of the camera body. In the above embodiment, the cover is disposed on the lower surface of the camera body. However, this is not the only one. The cover may be disposed at any surface of the upper surface and the side wall surface or the like. Further, the sliding direction and rotation of the cover -16 - 200807128 • The direction is not blocked by the above embodiment and can be changed as appropriate. The foregoing embodiments are related to the electronic camera. However, this is not the only one. The invention is applicable to any device that requires a cover. Although the present invention has been fully described by reference to the preferred embodiments thereof, the various modifications and modifications of the invention will be apparent to those skilled in the art. Therefore, unless such changes and modifications depart from the spirit of the invention, it should be inferred to be included.
