Description

  The present invention relates to a technical field of a lid support structure and an electronic device. More specifically, the present invention relates to a technical field for improving usability and downsizing after ensuring the simplification of the mechanism by pressing the lid in a direction different from the sliding direction with respect to the base body to move the lid to the open position.

  Imaging devices such as video cameras and still cameras, image display devices such as televisions, recording and reproducing devices that record and reproduce various information, communication terminal devices such as mobile phones, music reproducing devices, and various electronic devices such as game machines Some devices have a lid that can be opened and closed.

  Such a lid is configured to open and close, for example, a connector for connecting a connection cord, a slot for mounting a recording medium, and the like.

  As a lid body in a conventional electronic device, there is one that is rotatably and slidably supported by a base body that constitutes a part of a housing (see, for example, Patent Document 1).

  The electronic device described in Patent Document 1 has a structure in which the lid is slid and pulled out in the closed position, and then the pulled-out lid is rotated outward to the open position using the hinge mechanism as a fulcrum. .

JP 2001-10649 A

  However, in the imaging apparatus described in Patent Document 1, since the lid is slid once, pulled out, and then rotated, a two-step operation is necessary, and the operation when the lid is opened is troublesome. There is a problem that it is not easy to use.

  Further, since the lid body rotated to the open position exists outside the housing, for example, when the connection cord is connected to the connector section or when the recording medium is installed in the slot, the connection cord or the recording medium is the lid body. There is a risk that it will come into contact with the camera, which will also make it unusable.

  Furthermore, since a hinge mechanism serving as a pivot point is provided on the lid, there is a problem that the number of parts is large and the mechanism is complicated.

  On the other hand, there is a type in which a conventional electronic device is slid in one direction and the lid is opened, but in such a structure in which the lid is slid in one direction, it is the same as the sliding amount of the lid. It is necessary to form a guide groove extending in one direction of length. Therefore, it is necessary to secure a forming space for forming the guide groove in one direction, and there is a problem that the electronic device becomes longer in one direction and becomes larger.

  Accordingly, it is an object of the lid support structure and the electronic device of the present invention to overcome the above-described problems and to improve usability and downsizing while ensuring simplification of the mechanism.

The second guided pin 23 is positioned between the movement operation portion 20a and the operation projection 20b when viewed in plan, and the lid body 19 moves from the closed position to the open position, as will be described later. It becomes a fulcrum in the rotation of the lid 19 when it is started. Further, the second guided pin 23 is located on the right side of the operation projection 20b.

  The lid 19 is slidable by inserting the first guided pin 22 and the second guided pin 23 of the supported surface portion 21 positioned on the upper side into the guide portion 13 of the supporting surface portion 11 positioned on the upper side from below. Is engaged. Further, the lid 19 is inserted from above into the guide portion 13 of the supporting surface portion 11 where the first guided pin 22 and the second guided pin 23 of the supporting surface portion 21 located on the lower side are located. And are slidably engaged. In this way, the first guided pins 22 and 22 and the second guided pins 23 and 23 are slidably engaged with the guide portions 13 and 13, respectively, so that the lid body 19 moves to the base body 10. It is supported freely.

[Elastic member]
In the state in which the lid 19 is movably supported by the base body 10 as described above, the spring hook piece 22a provided on the first guided pin 22 of the lid 19 and the support surface portion 11 of the base body 10 are provided. The elastic member 24 is supported between the spring-hanging projection 11a. As the elastic member 24, for example, a tension coil spring is used.

  In the state where the elastic member 24 is supported between the lid body 19 and the base body 10 as described above, the lid body 19 is moved according to the engagement positions of the second guided pins 23 and 23 with respect to the guide portions 13 and 13. A biasing force in a predetermined direction is applied.

[Base body is placed]
As described above, when the base body 10 that supports the lid body 19 and the elastic member 24 is disposed inside the apparatus main body 2, it corresponds to the arrangement holes 16 a and 16 a formed in the side surface portion 16 of the base body 10. Thus, connectors and slots (not shown) are arranged. A connection cord or the like is connected to the connector, and a recording medium or the like is attached to the slot.

[Operation of lid]
Hereinafter, the operation of the lid 19 will be described (see FIGS. 5 to 12).

  First, a state where the lid 19 is held at the closed position will be described (see FIGS. 5 and 6).

  In the state where the lid 19 is held at the closed position, the arrangement opening 9 formed in the apparatus main body 2 is closed by the lid 19, and the connecting portion 12 of the base body 10 is closed. Therefore, the connection cord or the like to the connector or the recording medium or the like cannot be attached to the slot.

  In the closed position state, the lid body 19 has the first guided pins 22 and 22 engaged with the locking recesses 14a and 14a of the first guide grooves 14 and 14 in the base body 10, respectively. The guided pins 23 and 23 are engaged with substantially central portions in the longitudinal direction of the second guide grooves 15 and 15, respectively.

  Accordingly, the first guided pins 22 and 22 are urged by the elastic member 24 in the direction from the continuous points 13a and 13a toward the locking recesses 14a and 14a, respectively, so that the first guided pins 22 and 22 are The lid 19 is locked in the closed position by being pressed against the opening edges of the locking recesses 14a and 14a, respectively.

  At this time, the end edges of the stopper protrusions 20c and 20c of the lid body 19 are engaged with the front end portions 18a and 18a of the holding protrusions 18 and 18 provided on the front surface portion 17 of the base body 10, respectively (see FIG. 7). ).

  Hereinafter, the operation of the lid 19 from the closed position to the open position will be described.

  In the state in which the lid 19 is held at the closed position as described above (see FIGS. 5 to 7), the moving operation portion 20a of the closed surface portion 20 is pressed to the right (F1 direction shown in FIG. 6). Then, the lid body 19 is rotated about the second guided pins 23 and 23 and the opening operation of the lid body 19 is started.

  When the opening operation of the lid 19 is started, the tip end portions 18a and 18a of the holding projections 18 and 18 are pressed to the right by the stopper projections 20c and 20c, respectively, by the pressing operation on the moving operation unit 20a. The portions 18 and 18 are elastically deformed (see FIG. 8).

  When the lid 19 is rotated about the second guided pins 23, 23, the engagement of the first guided pins 22, 22 with the locking recesses 14a, 14a is released, and the first guided pins are released. The pins 22 and 22 are guided by the first guide grooves 14 and 14 to slide to the continuous points 13a and 13a (see FIGS. 9 and 10).

  At this time, the rotation of the lid 19 is performed against the urging force of the elastic member 24.

  The opening operation of the lid body 19 can also be started by operating the operation projection 20b of the closing surface portion 20 in a state where the lid body 19 is held at the closing position.

  That is, when the operation protrusion 20b is pressed from behind (F2 direction shown in FIG. 6), the second guided pins 23 and 23 are positioned to the right of the operation protrusion 20b as described above. Therefore, a rotational moment in the direction using the second guided pins 23 and 23 as fulcrums is generated in the lid body 19. Accordingly, the lid body 19 is rotated about the second guided pins 23 and 23 and the opening operation of the lid body 19 is started. When the lid 19 is rotated about the second guided pins 23, 23, the engagement of the first guided pins 22, 22 with the locking recesses 14a, 14a is released, and the first guided pins are released. The pins 22 and 22 are guided by the first guide grooves 14 and 14 and are slid to the continuous points 13a and 13a. The position of the lid 19 in which the first guided pins 22 and 22 are slid to the continuous points 13a and 13a is an intermediate position.

  When the lid 19 is moved to the intermediate position, the urging force of the elastic member 24 on the lid 19 is maximized.

  When the first guided pins 22 and 22 reach the continuous points 13a and 13a and the lid body 19 is slightly rotated, the first guided pins 22 and 22 are moved into the second guide grooves 15 and 15 respectively. Engaged. Accordingly, both the first guided pins 22 and 22 and the second guided pins 23 and 23 are engaged with the second guide grooves 15 and 15.

  When both the first guided pins 22 and 22 and the second guided pins 23 and 23 are engaged with the second guide grooves 15 and 15, the lid body 19 is moved to the first by the urging force of the elastic member 24. The guided pins 22 and 22 and the second guided pins 23 and 23 are guided by the second guide grooves 15 and 15 and are slid forward substantially toward the open position.

  When the lid 19 is slid toward the open position by the urging force of the elastic member 24, as described above, the second guide grooves 15, 15 are linearly inclined gently to the right as they go forward. Since it is formed, the lid 19 is inserted into the apparatus main body 2.

  At this time, the operation unit 20a for movement of the lid 19 is inserted into the apparatus main body 2. However, since the operation unit 20a for movement is formed in a planar shape, the lid 19 is inserted into the apparatus main body 2. Insertion can be performed smoothly.

  Further, since the moving operation portion 20a is formed in a flat shape, it is not necessary to secure a large space for inserting the lid 19 inside the apparatus main body 2, and the arrangement space inside the apparatus main body 2 is increased. It becomes possible to do. Therefore, it is possible to effectively utilize the space inside the apparatus main body 2 as the arrangement space for each component arranged inside the apparatus main body 2, and the freedom of arrangement of each component arranged inside the apparatus main body 2. It is possible to improve the degree.

  When the lid body 19 is slid toward the open position and the second guided pins 23, 23 are engaged with the one end portions 15a, 15a of the second guide grooves 15, 15, the sliding of the lid body 19 is stopped. The lid 19 reaches the open position and is held (see FIGS. 11 and 12). When the lid 19 has reached the open position, the elastic member 24 urges the lid 19 in the direction from the intermediate position to the open position, but the elastic member 24 is in a state where the length is the shortest. Yes, the biasing force of the elastic member 24 against the lid 19 is minimized.

  In a state where the lid 19 is held at the open position, a portion excluding the rear end of the lid 19 is inserted into the apparatus main body 2. Therefore, the operation protrusion 20b provided at the rear end of the lid 19 is positioned in the arrangement opening 9, and the operation protrusion 20b can be operated.

  In the state where the lid 19 is held in the open position, the arrangement opening 9 is opened, so that a connection cord or the like can be connected to the connector, and a recording medium or the like can be attached to the slot. At this time, since the cover 19 is inserted into the apparatus main body 2 except for a part thereof, connection work such as a connection cord to the connector, release work thereof, installation work to the recording medium etc. in the slot, and the like The lid 19 does not get in the way of the release work. Further, in these connection operations and the like, it is difficult for the cover 19 to come into contact with the connection cord, the recording medium, or the like.

  Accordingly, it is possible to improve workability in connection work such as a connection cable to a connector and the like, and it is possible to prevent the lid body 19 from falling off the base body 10 and the lid body 19 from being damaged.

  Further, since the lid 19 is inserted into the apparatus main body 2 except for a part in the open position, the lid 19 is hardly affected by an impact caused by an external force and can prevent the lid 19 from being damaged or damaged by the external force. it can.

  Next, the operation of the lid 19 from the open position to the closed position will be described.

  In a state where the lid 19 is held at the open position, when the operation projection 20b of the closing surface portion 20 is pressed backward, the lid 19 resists the urging force of the elastic member 24 and the first object is pressed. The guide pins 22 and 22 and the second guided pins 23 and 23 are guided by the second guide grooves 15 and 15 and are slid rearward substantially toward the closed position.

  As described above, in the state where the lid body 19 is held at the closed position, the urging force of the elastic member 24 against the lid body 19 is minimized. It can be done easily with a small force.

  When the first guided pins 22 and 22 and the second guided pins 23 and 23 are guided by the second guide grooves 15 and 15 and the lid body 19 is slid substantially rearward, the first guided pins are moved. The pins 22 and 22 are positioned at the continuous points 13a and 13a of the guide portions 13 and 13, and the lid 19 reaches the intermediate position (see FIGS. 9 and 10). At this time, the urging force of the elastic member 24 on the lid body 19 is maximized.

  When the lid body 19 reaches the intermediate position, the lid body 19 cannot slide further substantially rearward. Next, the lid body 19 uses the second guided pins 23 and 23 as fulcrums as the first guided pins 22, 22 is rotated in a direction toward the locking recesses 14a, 14a of the first guide grooves 14, 14. Accordingly, the first guided pins 22 and 22 are guided by the first guide grooves 14 and 14 by the urging force of the elastic member 24 and are slid toward the locking recesses 14a and 14a.

  The lid 19 stops rotating when the first guided pins 22, 22 reach the locking recesses 14a, 14a, and the first guided pins 22, 22 are engaged with the locking recesses 14a, 14a. Then, it is locked again in the closed position (see FIGS. 5 and 6).

  In a state in which the lid 19 is locked at the closed position, the end edges of the stopper projections 20c and 20c of the lid 19 are respectively provided on the front surface 17 of the base body 10 and the front end portions 18a of the holding projections 18 and 18 are provided. , 18a (see FIG. 7).

  As described above, in the electronic device 1, the base body 10 is supported by the base body 10 so as to be movable between the open position and the closed position, and has the operation unit 20a for movement, and the lid 19 is opened. And an elastic member 24 that urges toward the front. Further, in the electronic device 1, a guide including a first guide groove 14, 14 and a second guide groove 15, 15 bent with respect to the first guide groove 14, 14 in the base body 10. The first guided pins 22 and 22 and the second guided pins 23 and 23 slidably engaged with the guide portions 13 and 13 are provided on the lid body 19. .

  In the electronic device 1, in the configuration as described above, the first guided pins 22, 22 and the second guided pins 23, 23 are the first guide grooves 14, 14 and the second guide grooves, respectively. The lid body 19 is held in the closed position by being engaged with 15 and 15. Further, when the operation unit 20a for movement of the lid 19 held at the closed position is pressed in a direction different from the sliding direction toward the opening position of the lid 19, the second guided pins 23 and 23 are supported as fulcrums. As the cover body 19 is rotated, the first guided pins 22 and 22 are engaged with the second guide grooves 15 and 15, and the cover body 19 is slid toward the open position by the urging force of the elastic member 24. I am doing so.

  Therefore, in the electronic device 1, the lid body 19 is moved from the closed position to the open position by pressing the movement operation unit 20 a once in a direction different from the sliding direction toward the opening position of the lid body 19. Therefore, the operation when the lid 19 is opened is easy, and the usability can be improved.

  Further, the electronic device 1 does not require a special mechanism such as a hinge mechanism for rotating the lid 19, so that the number of parts can be reduced and the mechanism can be simplified.

  Further, since the lid 19 is not turned outward in the open position, the connection cord to be connected to the connector and the recording medium to be loaded in the slot do not come into contact with the lid 19 and further Usability can be improved.

  In addition, since the opening / closing operation of the lid body 19 includes a continuously rotating operation and a sliding operation, the length of the guide groove formed in the base body 10 in one direction (the sliding direction of the lid body 19) is rotated. It can be shortened by the amount of movement. Therefore, the formation space for forming the guide groove can be reduced in the above-described one direction, and the electronic device 1 can be downsized accordingly.

  In the electronic device 1, the lid 19 is biased in the direction toward the closed position in a state where the first guided pin 22 is engaged with the first guide groove 14, and the first guided pin In a state where 22 is engaged with the second guide groove 15, the lid body 19 is biased in the direction toward the open position. Further, the urging force is maximized in a state where the first guided pin 22 is engaged with the continuous point 13a that is the boundary between the first guide groove 14 and the second guide groove 15.

  Therefore, the direction of the urging force of the elastic member 24 against the lid 19 is reversed according to the position of the first guided pin 22 with respect to the guide portion 13 with respect to the continuous point 13a. The lid 19 can be reliably moved to the position.

  Moreover, in the electronic device 1, since the tension coil spring is used as the elastic member 24, the configuration is simple and the mechanism can be simplified.

  Furthermore, by using a tension coil spring that linearly expands and contracts as the elastic member 24, it is not necessary to secure a large space for moving the spring when using, for example, a toggle spring whose urging direction is reversed as the elastic member. The device 1 can be downsized.

  In the above, an example in which one elastic member 24 is used as a means for urging the lid 19 is shown. For example, a pair of support surface portions 11 and 11 of the base body 10 and a pair of covers 19 The elastic members 24 and 24 may be supported between the support surface portions 21 and 21, respectively. Thus, by arranging the two elastic members 24 and 24 on the opposite sides of the closing surface portion 20 of the lid body 19, the operation between the closed position and the open position of the lid body 19 is facilitated. Can do.

  Moreover, although the example which used the tension | pulling coil spring as the elastic member 24 was shown above, as a means to urge the cover body 19, it is not restricted to a tension coil spring, For example, a toggle spring, a leaf | plate spring, rubber | gum etc. Various elastic members can be used.

  In the electronic apparatus 1, as described above, the lid 19 is provided with the movement operation unit 20 a and the operation projection 20 b, and the lid 19 is moved by a pressing operation on the movement operation unit 20 a or the operation projection 20 b. It is moved from the closed position to the open position.

  Therefore, when the lid 19 is to be moved from the closed position to the open position, it is possible to select a portion to be operated and improve usability.

  In the electronic device 1, a part or all of the operation protrusion 20 b may be inserted into the apparatus main body 2 at the closed position. In this case, the opening operation of the lid body 19 can be started by a pressing operation on the movement operation unit 20a even when the operation protrusion 20b cannot be pressed at the closed position.

  Further, in the electronic device 1, a forward locking concave portion 14 a is formed in the first guide groove 14, and the first guided pin 22 is formed at the opening edge of the locking concave portion 14 a by the urging force of the elastic member 24. Is pressed to lock the lid 19 at the closed position.

  Therefore, since the shape of the locking recess 14a is simple, the lid 19 can be reliably locked at the closed position without causing an increase in manufacturing cost.

  Further, in the electronic apparatus 1, since the first guide groove 14 is formed in a gentle short arc shape, the lid body 19 can be reliably rotated around the second guided pin 23 as a fulcrum. It can be done smoothly.

  In the electronic device 1, since the biasing direction of the elastic member 24 is reversed during the operation in both the opening operation and the closing operation of the lid 19, the operator is informed when the spring is reversed. A so-called click feeling is imparted.

  Therefore, the operator can determine whether or not the lid 19 has moved to the open position or the closed position by providing a click feeling, and can ensure reliable operability and smooth operability.
