The electronic equipment 10 includes an elastic body 50 provided at the position of the housing 101 with which a back face of the lid 20 is brought into contact to elastically deflect the lid 20 in the direction to be opened, and a lock mechanism 40 for locking the closed state of the lid 20, and is configured so as to lock the lid 20 with the lock mechanism 40 after absorbing impact caused by energetically closing the lid 20 with the elastic body 50.

Description

  The present invention relates to an electronic device having a lid, and more particularly to an electronic device having a lid that is pivotally supported by a casing of the electronic device and locked in a closed state.

  Electronic devices such as printers and notebook computers are provided with connectors for connecting to external peripheral devices and the like. An openable / closable lid is provided at a portion where the connector is provided to prevent entry of dust and the like.

  Conventionally, as an electronic apparatus having this type of lid, for example, there is one shown in Patent Document 1 (Japanese Patent Laid-Open No. 2000-101264). In the electronic device, a rectangular opening formed on the rear surface of the main body in the electronic device, a connector provided in the opening, a rectangular opening / closing lid that covers the opening, and two opposite sides of the lid And a lid provided with guide pins provided in the vicinity of the respective end portions. On the other hand, a guide groove that guides the guide pin is formed in the vicinity of the opening, and a convex portion that can be overcome by the elasticity of the lid portion is provided inside the guide groove. The lid portion slides when the guide pin is guided by the guide groove, and rotates at a position where the guide pin gets over the convex portion.

  Therefore, the opening / closing operation by the opening / closing lid slides along the guide groove since the guide pin is fitted in the guide groove, and the lid portion is pulled out of the opening portion. At this time, the guide pin once hits the convex portion in the guide groove, but can get over the convex portion by the elastic force of the slit. Thereafter, the movement in the direction of the opening is stopped by the end of the guide groove blocked in an arc shape. Then, at that position, the guide pin is rotated as a fulcrum to close the opening. At this time, the position of the opening / closing lid is maintained because the guide pin is sandwiched between the end portion and the convex portion of the guide groove with almost the same size, and the rotation fulcrum does not move, and the opening / closing operation is stabilized.

  Further, as another conventional technique, for example, there is one shown in the following Patent Document 2 (Japanese Patent Laid-Open No. 2006-202972). The configuration includes a recess formed in the housing of the electronic device, a card insertion slot disposed in the recess, and a lid member provided on the housing that covers the recess so as to be freely opened and closed. The lid member is provided with an arm that integrally extends rearward from lower portions on both sides of the back surface. A pin-shaped projecting shaft projecting outward is formed at the tip of the arm. On the other hand, circular through holes as bearing recesses are formed on both side walls of the recess. The projecting shaft is inserted into the circular through hole, and the lid member is rotatably attached to the housing. Therefore, the opening / closing operation of the recess can be achieved by opening the recess by rotating the lid member forward and closing the recess by pushing the lid member.

  According to the above electronic device having a conventional lid, the portion of the housing provided with the connector or the like can be smoothly opened and closed by the lid, so that the entry of dust or the like into the portion provided with the connector can be prevented. . The configuration is simple with a small number of parts.

JP 2006-202972 A (paragraph [0012], paragraph [0013], paragraph [0017]) JP 2006-202972 A (paragraph [0017], paragraph [0019], paragraph [0022])

  However, in the prior arts shown in Patent Documents 1 and 2, the rebound that occurs when the lid is closed vigorously is not taken into consideration. For this reason, there is a problem that the lid is bounced back and remains in a closed state, and a reliable closed state cannot be obtained.

  Of course, it is conceivable to provide a lock mechanism that locks the closed state of the lid. However, even if the lock mechanism is locked once, the lock mechanism may be released from the lock state due to a strong impact due to rebound. As described above, in the prior art, the problems that occur when the lid is closed vigorously cannot be reliably solved.

  In general, the lid of such an electronic device is molded resin-molded, but it is inevitable that the dimensions of components such as the lid vary. Further, when the ratio of the length of the side in the longitudinal direction of the lid to the length of the other side exceeds a certain range, that is, when the length of the long side is longer than the length of the other side, the lid warps. May occur. For this reason, the lid attached to the casing of the electronic device is rattled. Therefore, there is a problem that when the lid is closed, a gap is generated between the lid and the casing due to rattling, and a reliable closed state cannot be obtained.

  Therefore, the present invention has an object to solve the above-described problems of the prior art and satisfy conventional demands, and in an electronic device having a lid, the lid has a lid that can reliably obtain a closed state with a simple configuration. The object is to provide an electronic device.

  In order to solve the above-mentioned problem, the invention according to claim 1 of the present application is an electronic apparatus having a lid that is pivotally supported by a casing of the electronic apparatus and opens and closes an opening in which a connector or the like is disposed. An elastic means (for example, an elastic body 50 in the embodiment) provided at a position of the casing where the back surface of the lid abuts and elastically biases the lid in the opening direction; and a closed state of the lid. And locking means (for example, a locking mechanism 40 in the embodiment) for locking.

  In the invention according to claim 2 of the present application, the locking means includes a locking protrusion (for example, a locking protrusion 402 in the embodiment) provided on the lid or the casing, and the casing or the lid. The locking protrusion (for example, the locking recess 403 in the embodiment) is provided on the cover, and when the lid is closed, the locking protrusion passes partway through the locking recess and then the elastic means It is configured to be configured so as to come into contact with the inner surface of the locking recess when the lid is returned.

  In the invention according to claim 3 of the present application, the elastic means is a U-shaped slit (for example, a U-shaped slit in the embodiment) formed on a plate-like contact surface provided on the housing side. A base portion (for example, base portion 503 in the embodiment) formed of a slit 502) and a tip portion (for example, tip portion 501 in the embodiment) provided at the end of the base portion so as to protrude toward the back surface of the lid. It is characterized by comprising.

  The attachment mechanism of the present invention has the following excellent effects.

  That is, according to the first aspect of the present invention, an elastic means for elastically biasing the lid in the opening direction is provided at the position of the casing where the back surface of the lid contacts, and the closed state of the lid is locked. Locking means are provided. According to such a configuration, the impact generated by closing the lid vigorously is absorbed by the elastic means, so that the lid does not bounce off the housing side and can be reliably locked by the locking means.

  Further, in the invention according to claim 2, the locking means comprises a locking projection and a locking recess, and when the lid is closed, the locking projection is partway through the locking recess and then the elastic means is used. It is set so as to come into contact with the inner surface of the locking recess when the lid is returned.

  According to such a configuration, when the lid is closed, the locking projection returns to the opening direction after an overstroke state in which the locking projection passes partway through the locking recess. Therefore, even if there are variations in the dimensions of the members constituting the locking means, etc., the locking protrusion reaches the locking recess when the cover is closed. Locking can be performed reliably without generating a locked state.

  Further, in the locked state, the locking projection comes into contact with the inner surface of the locking recess by the elastic force of the elastic means, so that rattling of the lid, the locking means, etc. is absorbed. Therefore, no rattling occurs in the closed state of the lid, so that the opening can be reliably closed with the lid without generating a gap between the lid and the housing.

  Further, in the invention according to claim 3, the elastic means protrudes in the direction of the back of the lid provided at the end of the base and the base having the deflection formed by the U-shaped slit on the plate-like contact surface. And a provided tip portion. For this reason, since a base that generates bending can be obtained simply by forming a slit, the structure of the elastic means is simple and the manufacture is easy.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. However, the embodiments shown below exemplify an electronic device having a lid for embodying the technical idea of the present invention, and the present invention is intended to specify the electronic device having the lid. The present invention is equally applicable to electronic devices having lids of other embodiments included in the scope of claims.

  As shown in FIGS. 1 and 2, the electronic device 10 according to an embodiment of the present invention has a flat box shape, and a lid 20 is disposed on one side surface. The lid 20 is for opening and closing the opening 30 in which the connector and the like of the electronic device 10 are arranged as shown in FIG. The opening 30 is a rectangle formed in the housing 101 (the ratio of the short side to the long side is about 1: 3), and the connector 302 faces the recess 301. The lid 20 has the same shape as the opening 30 and is pivotally supported by the housing 101 so as to be rotatable about one of its long sides, that is, the lower long side as a rotation center. The lid 20 is provided with a knob 201 at the center of the other long side.

  The opening 30 is shown in detail in the cross-sectional views of FIGS. 3, 4, and 5, but the recess 301 is formed by a rectangular box-shaped blindfold cover 303, and the connector 302 faces the bottom surface of the blindfold cover 303. A window 304 is formed. Therefore, the inside of the electronic device 10 is hidden by the blindfold cover 303. Further, the blind cover 303 constitutes a part of the housing 101.

  The lid 20 is pivotally supported around the lower long side as a rotation center, and the mechanism includes an arm 202 provided on the lid 20, a support shaft 305 formed at the tip of the arm 202, and a blindfold. A bearing (not shown) is provided on a side surface of the cover 303 for rotatably mounting the support shaft 305.

  A lock mechanism 40 is provided on the other side of the lid 20, that is, on both sides of the upper long side (near the upper end of the short side). The lock mechanism 40 includes a vertical piece 401 provided on the back surface of the lid 20, a lock projection 402 provided on the outer surface near the tip of the vertical piece 401, and a lock projection 402 provided on the blindfold cover 303. It is comprised from the recessed part 403 for a lock | rock formed so that engagement was possible.

  As shown in detail in FIG. 6, the locking projection 402 has a tapered surface 404. On the other hand, a taper surface 405 is formed in a portion where the locking protrusion 402 abuts on the locking recess 403.

  A plate-like contact surface 306 with which the upper back surface of the lid 20 contacts is provided at the upper edge of the opening 30. Elastic bodies 50 are provided near both ends of the contact surface 306. The elastic body 50 is shown in detail in FIG. 7, but it is bent by a tip 501 protruding from the surface of the contact surface 306 and a slit 502 formed by cutting the contact surface 306 into a U shape. It is comprised from the base 503 currently formed.

  Further, the bending of the base portion 503 is set to a state in which the distal end portion 501 is biased to a position below the contact surface 306 by further pressing the lid 20 after the back surface of the pushed lid 20 hits the distal end portion 501. ing.

  On the other hand, the positional relationship between the locking projection 402 and the locking recess 403 of the locking mechanism 40 in a state where the lid 20 is in contact with the contact surface 306 is such that the locking projection 402 integrated with the lid 20 is the locking recess 403. It is set to be in an overstroke state that passes through the interior partway.

  Next, the operation of the electronic device 10 according to the configuration of the above-described embodiment will be described. When the connector is not connected to the connector 302, the opening 30 is closed by the lid 20 as shown in FIGS. When connecting the connector to the connector 302, as shown in FIG. 3, the lid 20 is opened and the opening 30 is opened, and a predetermined connector is connected to the connector 302 exposed on the housing 101 surface. Here, since the lid 20 is locked by the lock mechanism 40 in the closed state, when the lid 20 is opened, the lid 20 is strongly pulled by the knob 201 to release the locked state of the lock mechanism 40.

  The operation of closing the lid 20 and closing the opening 30 will be described in detail with reference to FIGS. When closing the lid 20, the arm 20 is rotated around the support shaft 305 by pushing the lid 20, and the back surface of the lid 203 is brought into contact with the tip 501 of the elastic body 50. By further strongly pushing, the base portion 503 is bent and the distal end portion 501 is retracted. The lid 20 that has been pushed in is stopped from rotating when the back surface abuts against the contact surface 306.

  On the other hand, as shown in FIG. 6, in the lock mechanism 40, the lock projection 402 moves toward the lock recess 403 indicated by the arrow X by pushing the lid 20. Then, the locking projection 402 hits the outside of the locking recess 403, but when pushed further, the vertical piece 401 is bent in the direction indicated by the arrow Y by the contact of the tapered surfaces 404 and 405. Thereafter, the locking projection 402 reaches the locking recess 403 and passes through it. On the other hand, the vertical piece 401 returns from the bent state when the locking projection 402 is in the locking recess 403. That is, the lock mechanism 40 is in an overstroke state.

  When the lock mechanism 40 is in an overstroke state, the elastic body 50 is in a state in which the base portion 503 is bent and the distal end portion 501 is retracted from the surface of the contact surface 306. As a result, the lid 202 abuts against the contact surface 306 and stops rotating.

  Thereafter, when the pushing of the lid 20 is stopped, the bent base portion 503 is restored, and the lid 20 is rotated in the direction of returning slightly by the distal end portion 501. That is, the lid 20 is slightly pushed back by the elastic force of the elastic body 50 after stopping the pushing operation. As a result, the locking projection 402 slightly returns and its surface hits the inner surface of the locking recess 403, and the return of the lid 20 is stopped (see FIG. 4).

  Therefore, according to the above-described embodiment of the present invention, when the lid 20 is closed with force, the back surface contacts the elastic body 50 and then contacts the contact surface 306. Therefore, the impact force generated when the cover 20 contacts the contact surface 306 is elastic. 50 is absorbed. Therefore, the lid 20 does not bounce off. Therefore, the lock mechanism 40 is not unlocked by rebounding from the locked state.

  In addition, after an overstroke state in which the locking projection 402 passes partway through the locking recess 403, the lid 20 returns to the opening direction. Therefore, due to warpage of the lid 20, variations in the components of the lock mechanism 40, the locking projection 402 does not reach only before the locking recess 403 when the lid 20 is pushed to the end. That is, when the lid 20 is closed, the locking protrusion 402 always reaches the locking recess 403, so that an incomplete locking state of the locking mechanism 40 does not occur and a reliable locking state is obtained.

  In particular, if the lid 20 is a horizontally long rectangle, warpage is likely to occur due to variations in resin molding, but even if this warpage occurs, it is absorbed by the overstroke so that a reliable locked state can be obtained. This is effective when applied to the electronic device 10 in which the opening 30 is rectangular.

  As described above, when the lid 20 is closed, the locking projection 402 returns to the position over the locking recess 403 and then returns due to the elastic force of the elastic body 50. As a result, the locking mechanism 40 is in a locked state with the locking projection 402 elastically contacting the inner surface of the locking recess 403. Therefore, even if the members constituting the lock mechanism 40 have a large variation and the lid 20 is bent or the like, the lid 20 is in an elastic contact state in the lock mechanism 40, so that the lid 20 does not rattle. And no gap between the housing 101 and the housing 101.

  Further, since the elastic body 50 can form the base portion 503 by providing the slit 502 on the contact surface 306, the structure thereof is simple and can be manufactured integrally with the blindfold cover 303 by resin molding.

  In the above embodiment, the lid 20 is rectangular. However, the present invention is not limited to this, and when the opening portion of the opening 30 is square, the shape of the lid 20 is the same, such as a square. Various changes may be made.

  In the above embodiment, the locking mechanism 40 has the locking protrusion 402 on the lid 20 side and the locking recess 403 on the cover side 303, that is, the housing 101 side. However, in the present invention, the locking projection 402 may be provided on the housing 101 side and the locking recess 403 may be provided on the lid 20 side.

  In the above embodiment, the connector 302 is disposed in the opening 30. However, the present invention is not limited to this, and an insertion slot or the like for various cards may be disposed.
