JP 2006-350055 A

  However, the opening / closing direction of the slide opening / closing lid and the rotation opening / closing lid is fixed in one direction. That is, in the case of a slide opening / closing type lid body, the lid body can be opened / closed only by advancing / retreating along a predetermined direction. Moreover, if it is a rotation opening-and-closing type lid body, a lid body can be opened and closed only by rotating along a predetermined direction.

  For this reason, when a hard disk drive is attached to the camera body, it may be difficult to open and close the lid depending on the attachment position of the hard disk drive. If the lid cannot be opened and closed due to the installation of the hard disk drive, the setting of the monitoring camera device cannot be executed with the hard disk drive installed, and the hard disk drive must be removed for each installation, which is inconvenient.

  Not only the above-described monitoring camera device but also an electronic device composed of two units may cause a problem that it is difficult to open and close the lid by combining the two units. Also in this case, the unit must be separated for each setting as described above, which is inconvenient.

  Moreover, even in an electronic device configured with one unit, it may be difficult to open and close the lid depending on the installation location. In this case, the electronic device must be moved to a position where the lid can be opened and closed for each setting, which is inconvenient.

  Therefore, an object of the present invention is to avoid that the lid cannot be opened and closed depending on the use mode and installation position of the electronic device.

  An electronic apparatus according to the present invention includes a main body (1) in which an opening (1a) is formed, and a lid (2) for opening and closing the opening (1a) of the main body (1), The main body (1) and the lid body (2) are provided with an engagement mechanism (3) for detachably attaching the lid body (2) to the main body (1). The engagement mechanism (3) can be disengaged by applying an operating force in a direction within a predetermined angle range (θ) to the lid (2) attached to the cover (2). In such an electronic device, the main body (1) and the lid (2) have a pair of sliding contact surfaces (51a, 52a) that are in sliding contact with each other in a state where the lid (2) is attached to the main body (1). ) Is formed at a position different from the engagement mechanism (3), and at least one sliding contact surface extends along a predetermined direction (93) within the predetermined angle range (θ), and the lid The sliding contact surface (52a) of the body (2) can slide in the predetermined direction (93) along the sliding contact surface (51a) of the main body (1).

  According to the electronic device, for some reason, an operating force in a direction within a predetermined angle range cannot be directly applied to the lid attached to the main body, and an operating force in a direction different from the lid direction is applied. Even if it is unavoidable, the operation force generates a component force in the direction of sliding the sliding contact surface of the lid along the sliding contact surface of the main body, that is, a component force in a predetermined direction. The engagement between the main body and the lid by the engagement mechanism is released by the component force. As a result, the lid is opened or the lid is removed from the main body.

  In a specific aspect of the electronic apparatus, the main body (1) and the lid body (2) have a locking mechanism (4) for locking the lid body (2) to the main body (1). It is possible to rotate the lid (2) with the locking position (R1) of the locking mechanism (4) as a fulcrum, and by rotating the lid (2). The operating force in the direction (92) within the predetermined angle range (θ) is applied to the lid (2).

  According to the above specific aspect, an operation force in a direction within a predetermined angle range is applied to the lid attached to the main body by the turning operation of the lid using the locking position of the locking mechanism as a fulcrum. Therefore, the engagement of the engagement mechanism is released, and thus the lid is opened or the lid is removed from the main body. Therefore, it is possible to selectively execute opening and closing of the lid body by the turning operation and opening and closing of the lid body using the sliding contact surface.

  More specifically, the opening (1a) is formed across two surface regions (131, 132) facing different directions from each other on the surface of the main body (1), and the lid (2) is a first lid part (21) along one of the two surface areas (131, 132) and a second lid part along the other surface area (132). (22) A rotation operation portion (211) for rotating the lid (2) with the locking position (R1) as a fulcrum is formed on the surface of the first lid (21). In addition, the pair of sliding surfaces (51a, 52a) is subjected to an operating force in the direction (94) along the surface of the second lid part (22) with respect to the lid (2). Sometimes, the main body (1) so that the sliding surface (52a) of the lid (2) slides in the predetermined direction (93) along the sliding surface (51a) of the main body (1). ) And the lid (2).

  As a result, the lid can be opened and closed by the pivoting operation of the lid, and even if the pivoting operation part is hidden and the lid cannot be opened and closed by the pivoting operation for some reason, By using the contact surface, that is, by applying an operation force in a direction along the surface of the second lid portion and generating a component force in a predetermined direction, the lid body can be opened.

  The said electronic device WHEREIN: The said cover body (2) is connected to the said main body (1) with the connection member (7), The said cover body (7) remains in the connection state by this connection member (7). It is preferable that 2) can be engaged with and disengaged from the main body (1). This prevents the lid from falling off the main body and the lid from being lost.

  According to the electronic device according to the present invention, it is possible to prevent the lid from being unable to be opened and closed depending on the usage mode and installation position of the electronic device.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention implemented in a monitoring camera device will be specifically described below with reference to the drawings.

  As shown in FIG. 1, the monitoring camera device according to the present embodiment includes a camera body 1 and a hard disk drive 6. As shown in FIGS. 1 and 2, the hard disk drive 6 can be detachably attached to the camera body 1. By attaching the hard disk drive 6 to the camera body 1, it is possible to record an image captured by the camera body 1 on the hard disk drive 6.

  As shown in FIG. 3, the camera body 1 includes an imaging mechanism 11 necessary for capturing an image, an operation unit 12 for setting and operating a monitoring camera device, and the like. As shown in FIG. 3, the camera body 1 has an opening 1 a, and the opening 1 a is divided into two surface areas facing different directions, specifically, an upper surface area 131 and a side area 132. Straddling. An operation unit 12 is installed inside the opening 1a.

  As shown in FIGS. 2 and 3, a lid 2 for opening and closing the opening 1a is detachably attached to the camera body 1. The lid body 2 includes a first lid body portion 21 and a second lid body portion 22. The first lid portion 21 and the second lid portion 22 are configured to extend along the upper surface region 131 and the side surface region 132, respectively, when the lid body 2 is attached to the camera body 1. An operation groove 211 is formed on the surface of the first lid portion 21.

  As shown in FIG. 3, the camera body 1 and the lid body 2 are provided with an engagement mechanism 3 for detachably attaching the lid body 2 to the camera body 1. Specifically, the engagement mechanism 3 has the following configuration.

  That is, the camera body 1 is formed with a pair of side walls 141 and 142 at a position on the upper surface region 131 side of the opening 1a. The pair of side walls 141 and 142 extend from the edge of the opening 1a to the inside of the camera body 1 and face each other. The pair of side walls 141 and 142 are provided with engagement holes 311 and 312, respectively.

  Further, the lid 2 is formed with engaging portions 321 and 322 as shown in FIG. Specifically, the engaging portion 321 has flexibility and extends from the back surface 2 b of the lid body 2 substantially in parallel with the first lid body portion 21. A protrusion 321 a is formed at the distal end of the engagement portion 321, and the protrusion 321 a is fitted into the engagement hole 311 and hooked when the lid body 2 is attached to the camera body 1. In addition, the protrusion 321a is formed with a pair of tapered surfaces extending in a C shape from the tip of the protrusion 321a, and the pair of taper surfaces are respectively a distal end side and a proximal end side of the engaging portion 321. Located in.

  Similarly, the engaging portion 322 has flexibility and protrudes from the back surface 2 b of the lid body 2. A protrusion 322 a that fits into the engagement hole 312 and is hooked is formed at the tip of the engagement portion 322. In addition, the protrusion 322a is formed with a pair of tapered surfaces extending from the tip of the protrusion 322a in a C-shape, and the pair of taper surfaces are respectively a distal end side and a proximal end side of the engaging portion 322. Located in.

  According to the engagement mechanism 3, the lid 2 is attached to the camera body 1 as follows. First, when the lid 2 is to be attached to the camera body 1, the protrusions 321a and 322a of the engaging portions 321 and 322 hit the edge of the opening 1a. However, by pushing the lid 2 toward the camera body 1, the protrusions 321a and 322a enter the inside of the opening 1a while bending the engaging portions 321 and 322. At this time, since the projecting portions 321a and 322a are formed with tapered surfaces at positions on the distal ends of the engaging portions 321 and 322, the projecting portions 1a can easily enter the inside of the opening 1a. The protrusions 321a and 322a that have entered the inside of the opening 1a abut against the side walls 141 and 142, respectively, and an elastic force generated by the bending of the engaging portions 321 and 322 is applied toward the side walls 141 and 142.

  Then, by further pushing the lid 2 toward the camera body 1, the protrusions 321 a and 322 a reach the engagement holes 311 and 312, respectively, and fit into the engagement holes 311 and 312 by the elastic force. As a result, the protrusions 321a and 322a are respectively hooked in the engagement holes 311 and 312 (see FIG. 5), so that the lid 2 is engaged with the camera body 1.

  On the other hand, the lid 2 is opened as follows or removed from the camera body 1. First, as shown in FIG. 5, when an operating force in the direction 91 from the distal end to the proximal end of the engaging portions 321 and 322 is applied to the lid body 2, the protruding portions 321 a and 322 a are engaged with the engaging holes 311 and 312. I hit the edge of. However, since the projecting portions 321a and 322a are formed with a tapered surface at a position on the proximal end side of the engaging portions 321 and 322, the projecting portions 321a and 322a are engaged while the engaging portions 321 and 322 are bent. Pull out from the joint holes 311 and 312. Thereby, the engagement between the camera body 1 and the lid body 2 by the engagement mechanism 3 is released, and thus the lid body 2 is opened or removed from the camera body 1.

  Since the projecting portions 321a and 322a are formed with a tapered surface at the base end side positions of the engaging portions 321 and 322, even when an operation force in a direction different from the direction 91 is applied, Is within the predetermined angle range θ, the protrusions 321a and 322a can be pulled out of the engagement holes 311 and 312. That is, in the surveillance camera according to the present embodiment, the engagement of the engagement mechanism 3 can be released by applying an operation force in a direction within a predetermined angle range θ.

  As shown in FIG. 5, the camera body 1 and the lid body 2 are provided with a locking mechanism 4 for locking the lid body 2 to the camera body 1 so as to be rotatable. Specifically, the locking mechanism 4 has the following configuration. That is, as shown in FIGS. 4 and 5, the lid 2 has a locking portion 42 for hooking (locking) to the edge 132 a of the opening 1 a, and the first lid of the second lid portion 22. It is formed at the end 22 a opposite to the body part 21. The camera body 1 is formed with a locking recess 41 at a position near the edge 132a of the opening 1a. The latching recess 41 accommodates the latching portion 42 that is hooked on the edge 132 a, thereby preventing the latching portion 42 from shifting to the inside of the camera body 1.

  When the lid body 2 is attached to the camera body 1, the lid body 2 is engaged with the camera body 1 by the locking mechanism 4 while the locking portion 42 is hooked (locked) on the edge 132 a of the opening 1 a. . Thereby, the lid 2 attached to the camera body 1 is not easily displaced from the opening 1a. In addition, from the viewpoint of preventing the lid 2 from being displaced from the opening 1a, it is preferable that the engagement mechanism 3 is disposed away from the locking mechanism 4. Specifically, in the surveillance camera according to the present embodiment, the engagement mechanism 3 is arranged at a position in the vicinity of the first lid 21 as shown in FIG.

  According to the locking mechanism 4, as shown in FIG. 6, the lid body 2 can be rotated with a position (locking position) R <b> 1 where the locking portion 42 is locked as a fulcrum. When the operator of the monitoring camera actually performs the rotation operation of the lid body 2, the operation groove 211 described above is used. That is, the operator applies an operation force in the direction 91 to the lid portion 2 by placing a finger on the operation groove 211. When the lid 2 tries to move in the direction 91 by the operating force, the latching portion 42 of the latching mechanism 4 is hooked on the edge 132a of the opening 1a, so the lid 2 tries to rotate around the latching position R1. And Therefore, the applied operation force in the direction 91 is decomposed into a force (component force) in the direction 92 for rotating the lid body 2 and a force (component force) in the direction 921 toward the locking position R1.

  Then, the engagement of the engagement mechanism 3 is released by the component force in the direction 92. Further, since the locking portion 42 is pushed toward the locking position R1 by the component force in the direction 921, even after the engagement of the engagement mechanism 3 is released, the locking mechanism 4 at the locking position R1 is released. Locking remains maintained. Therefore, the lid 2 is opened while rotating. In view of the fact that the operation of rotating the lid 2 using the operation groove 211, the operation groove 211 can be grasped as a rotation operation unit.

  As shown in FIG. 5, an interference prevention groove 23 opened to the outside of the camera body 1 is formed between the edge 22a of the lid 2 and the edge 132a of the opening 1a at the locking position R1 serving as a fulcrum. Has been. By forming the interference prevention groove 23 in this way, interference between the edge 22a of the lid 2 and the edge 132a of the opening 1a is prevented when the lid 2 is rotated as shown in FIG.

  As shown in FIG. 5, the camera body 1 and the lid body 2 have a pair of sliding contact surfaces 51 a and 52 a that are in sliding contact with the camera body 1 in a state where the lid body 2 is attached. They are formed at different positions. Each of the pair of sliding contact surfaces 51a and 52a extends along a predetermined direction 93 within a predetermined angular range θ. The sliding contact surface 52a of the lid 2 can slide in a predetermined direction 93 along the sliding contact surface 52a of the camera body 1, as shown in FIG.

  Specifically, as shown in FIGS. 3 to 5, the camera body 1 and the lid 2 are formed with a recess 51 and a protrusion 52 that can be fitted to each other. The pair of slidable contact surfaces 51 a and 52 a are respectively formed on portions of the inner surface of the recess 51 and the side surface of the protrusion 52 that are located on the opposite side of the interference prevention groove 23. In addition, a predetermined direction 93 in which the pair of sliding contact surfaces 51 a and 52 a extends is inclined obliquely with respect to a direction 94 along the surface of the second lid portion 22.

  Therefore, by using the sliding contact surfaces 51a and 52a, the lid body 2 can be opened or removed from the camera body 1 not only by the rotation operation described above but also by the following operation. . That is, when the lid 2 is attached to the camera body 1 (FIG. 5), the operator uses the interference prevention groove 23, specifically, the operator hooks a nail into the interference prevention groove 23, and the lid An operating force in the direction 94 is applied to 2. The direction 94 is a direction outside a predetermined angle range θ in which the engagement mechanism 3 can be disengaged. However, due to the operation force in the direction 94, the component force in the predetermined direction 93 is a pair of directions. It occurs on the sliding contact surfaces 51a and 52a. This is because the pair of sliding contact surfaces 51 a and 52 a extend along a predetermined direction 93 inclined obliquely with respect to the direction 94, and the sliding contact surface 52 a is slid by the operating force in the direction 94. This is because it is pressed against 51a.

  Thereby, the sliding contact surface 52 a of the lid body 2 slides in a predetermined direction 93 along the sliding contact surface 51 a of the camera body 1. Since the predetermined direction 93 is a direction within a predetermined angle range θ in which the engagement mechanism 3 can be disengaged, the sliding of the sliding contact surface 52a causes the sliding as shown in FIGS. The protrusions 321a and 322a of the engagement mechanism 3 come out of the engagement holes 311 and 312. Therefore, the engagement between the camera body 1 and the lid 2 by the engagement mechanism 3 is released.

  Thus, even if the operating force applied to the lid 2 is an operating force in the direction 94 outside the predetermined angle range θ, the lid 2 can be removed from the camera body 1.

  In the surveillance camera according to the present embodiment, as shown in FIG. 3, the lid 2 is connected to the camera body 1 by the connecting member 7 while being able to be engaged with and disengaged from the camera body 1. It is preferable. This prevents the lid 2 from falling off the camera body 1 and the lid 2 from being lost. In the monitoring camera according to the present embodiment, a tape-shaped member is used as the connecting member 7.

  According to the monitoring camera described above, due to some circumstances, specifically, when the hard disk drive 6 is attached to the camera body 1 as shown in FIG. When the operating force in the direction 92 within the predetermined angle range θ cannot be directly applied to the attached lid body 2 and the operating force in the direction 94 different from the direction 92 must be applied, As described above, since the component force in the predetermined direction 93 is generated on the pair of sliding contact surfaces 51a and 52a by the action of the operating force, as shown in FIG. And the lid 2 are disengaged. As a result, the lid 2 is opened as shown in FIG. 11 or the lid 2 is removed from the camera body 1.

  In the above-described monitoring camera, when the hard disk drive 6 is not attached to the camera body 1 (FIGS. 2 and 3), the rotation of the lid 2 with the locking position R1 of the locking mechanism 4 as a fulcrum is performed. The engagement mechanism 3 can be disengaged by a moving operation, so that the lid 2 can be opened or the lid 2 can be removed from the camera body 1.

  Therefore, according to the usage mode of the monitoring camera, the lid body 2 can be selectively opened and closed by the turning operation and the lid body 2 can be opened and closed using the sliding contact surfaces 51a and 52a. Thus, it is avoided that the lid body 2 cannot be opened and closed. Further, according to the monitoring camera described above, the lid body 2 can be opened by using the sliding contact surfaces 51a and 52a even when the rotation operation of the lid body 2 becomes impossible depending on the installation position.

  In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim. In the monitoring camera described above, both the sliding contact surfaces 51a and 52a extend along the predetermined direction 93 within the predetermined angle range θ, but the present invention is not limited to this. For example, as shown in FIG. 12, only the slidable contact surface 51a may extend along the predetermined direction 93, or only the slidable contact surface 52a may be in the predetermined direction as shown in FIG. The aspect extended along 93 may be sufficient. In any embodiment, as in the monitoring camera described above, a component force in a predetermined direction 93 is generated by applying an operation force in the direction 94 along the surface of the second lid portion 22.

  Further, the engagement mechanism 3, the locking mechanism 4, and the connecting member 7 are not limited to those described above, and various types can be employed. And the technique mentioned above is applicable not only to the camera for surveillance but various electronic devices, such as a video camera.
