Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a front panel drop-off prevention mechanism and an electronic device including the front panel. The present invention relates to an electronic device including

  An electronic device may employ a structure in which a front panel is opened and closed to open and close a front side opening. For example, as shown in FIG. 8, in a studio single device 100 that is stored and used in a shelf in a broadcasting business or the like, the front panel 110 is removed from the housing 101 in order to prevent erroneous operation. The power switch 102 in the opening 101a is turned on / off.

  As a structure for opening and closing the front side opening, there is a so-called flipper door. The flipper door lifts the lower end of the door body (front panel) that hangs vertically downward and rotates it 90 degrees to make it horizontal, and then slides it into the front side opening together with a member that supports the rotation. As a result, the front side opening can be opened (Patent Document 1). In front panels of in-vehicle audio systems and the like, the lower end moves together with a slider that can slide in the front-rear direction on the slider base in the front side opening, and at the same time, the upper end is in a groove on both sides of the front side opening. The front side opening can be opened and closed by moving up and down (Patent Document 2).

  In these Patent Documents 1 and 2, since the front panel is connected to the front side opening side of the housing so as to be relatively movable and is engaged so as not to be detached, the front panel itself cannot be removed.

  By the way, in the recording paper cassette that is inserted into and removed from the front opening, the recording paper cassette is engaged so as to be placed on a rail fixed to the side surface of the front opening and is slidable in the front-rear direction. It has also been attempted to prevent the rear end portion from being inadvertently dropped by locking the rear end portion to a stopper fixed in the vicinity of the portion. This recording paper cassette can be removed from the engagement with the stopper by being pulled out from the opening on the front side and pulled upward (Patent Document 3).

  However, each time the power switch 102 is turned on / off, such as the front panel 110 of the studio unit 100, it is necessary to remove it from the front opening 101a side of the housing 101. At this time, another operation such as the power switch 102 must be performed while holding the removed front panel 110 with one hand. In such a situation, there is a problem that the front panel 110 may be dropped, another operation is difficult, and workability is poor.

  In addition, since the front panel 110 includes the liquid crystal display unit 111 and various operation buttons 112, the cable 105 is connected to the circuit board on the apparatus main body side. For this reason, if the front panel 110 is dropped, there is a possibility that a tensile stress (load) is applied to the cable 105 unnecessarily and the cable 105 is disconnected. Further, even when the front panel 110 is removed with caution without noticing the cable 105, there is a possibility that an unnecessary pulling load is applied to cause disconnection.

  Therefore, when the adoption of the front panel mounting structure described in Patent Documents 1 and 2 is studied, both are assembled by a complicated mechanism and are not suitable as a structure that is simply attached and detached. Further, the front panel is not completely removed from the front side opening side of the housing, and cannot be employed in a structure in which the front side opening of the studio unit is opened and closed by the front panel.

  That is, in the front panels described in Patent Documents 1 and 2, the front-side opening can be opened and closed only by applying a driving force so as to reciprocate a specified route such as a rail. For this reason, in order to realize opening and closing of the front-side opening, this front panel requires complicated components such as a rail that guides in the horizontal direction and a member that is rotatably supported. In addition, the front panel cannot be easily removed from the front opening side of the housing, and the required complete detachment is impossible.

  Although it is a completely different technical field, even if the technique (rail) described in Patent Document 3 is to be applied, it is only supported so as to be slidable in the horizontal direction. Simply slide toward the inside of the opening. Further, the stopper is a separate member from the rail and has only a function of simply stopping. That is, in the technique described in Patent Document 3, it is necessary to provide two types of a slide function and a stopper function, and it is easy and easy for an electronic device that opens and closes the front side opening of a single studio device with a front panel. It cannot be adopted.

  The present invention has been made in view of the above-described circumstances. While maintaining the front panel in the same manner as when the front panel is completely detached from the front-side opening, the front panel can be easily and completely completed as necessary. An object of the present invention is to provide an electronic device including a front panel drop-off prevention mechanism and a front panel that can be removed.

  In order to solve the above-described problems, the configuration of the present invention includes a case-side member fixed to a device case having an opening on the front side, and a front-side opening that is attached to and detached from the front-side opening of the device case. The panel side member is fixed to the front panel and extends in the opening / closing direction and then bends at the front end side. The casing side member engages with the extension portion of the panel side member and A guide unit that guides movement in the opening and closing direction; and a limiting unit that restricts movement of the bent portion of the panel side member in the separation direction when the front panel is separated from the front side opening by a predetermined distance. The guide portion is open at an upper portion, and is characterized in that the extension portion of the panel side member is received and guided from above so as to be inserted and removed.

  According to the configuration of the present invention, only the two parts of the casing side member and the panel side member are fixed to the equipment casing and the front panel near the front side opening, respectively, and the panel side member is guided to the casing side member while being guided to the front side. The panel can be moved back and forth in the opening / closing direction. Moreover, when the front panel is opened with the front side opening opened, the casing side member restricts the panel side member from further separation when the front panel attempts to separate more than a predetermined distance, and the housing side member completely separates and falls. You can avoid that. And it can also remove completely from a housing | casing side member only by moving a panel side member together with a front panel. Therefore, it is possible to avoid giving an unreasonable load to the cable or the like by holding the front panel in a state equivalent to a state in which the front panel is completely detached from the device housing side and dropping the front panel. While the operator can perform various operations without holding it, it can be completely removed as needed.

Embodiment

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a schematic overall configuration of a single studio device according to an embodiment of the present invention, FIG. 2 is a perspective view showing a front panel drop-off preventing mechanism attached to the single studio device, and FIG. It is a figure which shows the components which comprise a panel drop-off prevention mechanism, (a) is a top view, (b) is a front view, (c) is a side view, FIG. 4 is FIG. 3 which comprises the front panel drop-off prevention mechanism. FIG. 5A is a plan view, FIG. 5B is a front view, and FIG.

  As shown in FIG. 1, for example, the studio unit device (electronic device) 10 according to the present embodiment is engaged horizontally with an engagement rail 12 on the side surface of the housing 11 in a shelf in a studio of a broadcasting office. It is stored by sliding it into The studio unit 10 has an opening on the front side of the housing 11, and a screw (not shown) is inserted into a screw hole 13a of an L-shaped bracket 13 fixed to the outer side surfaces on both sides of the front side opening 11a. It is designed to be fixed to the shelf side with screws.

  The studio unit 10 has a front panel 21 attached to the front side of the housing 11 and operates various operation buttons 23 while confirming the display of the liquid crystal display unit 22 disposed on the front side of the front panel 21. It is supposed to be. The front panel 21 is electrically connected to the main body side circuit board in the housing 11 via a flat cable 24 attached to the back surface side, and is attached to and detached from the front surface side of the housing 11 to be opened on the front surface side 11a. Can be opened and closed. In the studio single device 10, the front panel 21 is removed and the power switch 14 in the front opening 11a is turned on / off, so that it is possible to prevent the power from being turned off by mistake. It is supposed to be.

  The studio unit 10 has a slide block 25 that can be slid left and right by a predetermined distance on both ends of the front panel 21 as a lock mechanism that attaches the front panel 21 to the front opening 11a side of the housing 11 and restricts attachment / detachment. It is attached. The slide block 25 locks the front panel 21 in the attached state when the sheet metal part 13b of the L-shaped metal fitting 13 enters into a not-shown sheet thickness slit and is slid outward. When it is slid toward it, the lock is released. The locking mechanism of the front panel 21 is not limited to the slide block 25, and may be a structure that is simply screwed.

  In the studio unit 10, as a mechanism for preventing the front panel 21 from dropping off from the housing 11 side and dropping, the receiving brackets 19 are fixed to both ends of the front surface side opening 11 a of the housing 11 on the lower surface 11 b side. On the other hand, drawer metal fittings 29 are fixed to both ends on the back side of the front panel 21.

  As shown in FIGS. 2 and 3, the metal fitting 19 is integrally provided with a fixed portion 31, a facing portion 32, and a parallel portion 33 by machining a metal plate material such as cutting and bending. It is made into a shape. The fixed portion 31 is formed in a substantially square shape, and is fixed to the lower surface 11b of the front-side opening 11a of the housing 11 with a rivet 31a. Needless to say, the rivet 31a may be replaced with other fixing means such as screws.

  The facing portion 32 is raised so as to face the back surface of the front panel 21 by extending and bending one end side of the fixed portion 31 parallel to the opening surface of the front-side opening 11 a of the housing 11. The parallel portion 33 is a fixed portion 31 parallel to the direction orthogonal to the opening surface of the front-side opening 11a of the housing 11, in other words, the moving direction of the front panel 21 (opening / closing direction of the front-side opening 11a of the housing 11). The other end side is extended and bent, and is raised so as to face the inner side surface 11c of the front side opening 11a.

  The facing portion 32 and the parallel portion 33 of the metal fitting 19 are integrally formed with the fixed portion 31 so as to be orthogonal to each other, and are larger than the thickness of an extension portion 36 of a drawer fitting 29 described later. The inner surface 33a of the parallel portion 33 is formed so as to be separated from one end side 32a of the facing portion 32 at an interval of.

  As shown in FIGS. 2 and 4, the drawer metal fitting 29 is integrally provided with an extending portion 36, a fixing portion 37, and an orthogonal portion 38 by machining a metal plate material such as cutting and bending. It is made into a shape.

  The extending portion 36 is extended and formed to have a length enough to separate the front panel 21 from the front-side opening 11a of the housing 11 by a distance sufficient to turn on / off the power switch 14. The extending portion 36 is formed with a flange portion 36a that is parallel to the extending direction and has a long side that is bent at a right angle to improve strength. The fixing portion 37 is formed by bending a base end portion in the extending direction of the extending portion 36 into a right-angled flange shape, and is fixed to the back side of the front panel 21 by fixing means such as screwing (not shown). That is, the extending part 36 extends from the back side of the front panel 21 in the opening / closing direction of the front side opening 11 a of the housing 11.

  In the orthogonal part 38, the other end side of the extending part 36 is bent in a direction orthogonal to the extending direction. In other words, the orthogonal portion 38 forms a bent portion and is orthogonal to the moving direction (opening / closing direction) of the front panel 21 that opens and closes the front opening 11a of the housing 11 and the opening surface of the front opening 11a. Face each other in parallel.

  For this reason, the drawer fitting 29 is in an engaged state in which the extended portion 36 is easily inserted and accommodated from the upper opening side between the end 32a of the facing portion 32 of the fitting 19 and the inner surface 33a of the parallel portion 33. can do. In this state, the drawer metal fitting 29 is supported by the extension portion 36 on the fixed portion 31 and guided between the facing portion 32 and the parallel portion 33 of the receiving metal fitting 19, and is inserted into the front side opening 11 a of the housing 11. The front panel 21 can slide freely in the direction of approaching / separating toward the front, and the front panel 21 can slide in a direction to open and close the front side opening 11a of the housing 11. On the other hand, when the front panel 21 is separated from the front-side opening 11 a of the housing 11 by the length of the extending portion 36, the orthogonal portion 38 of the drawer fitting 29 is stopped by the facing portion 32 of the receiving fitting 19. Further slides are limited. Further, the drawer fitting 29 can be easily detached from the upper opening of the facing portion 32 and the parallel portion 33 of the receiving fitting 19 by moving the extending portion 36 upward perpendicular to the opening and closing direction. The panel 21 can be completely easily removed from the housing 11 side. That is, the metal fitting 19 constitutes a guide part composed of the first and second bent parts by the facing part 32 and the parallel part 33, and the facing part 32 also serves as a limiting part. Here, since the receiving metal part 19 has the facing part 32 and the parallel part 33 formed on the orthogonally adjacent end sides of the fixed part 31, respectively, the facing part 32 and the parallel part 33 are in a positional relationship in which they face each other directly. Absent. However, when viewed from the front of the front side opening 11a of the housing 11, the end 32a of the facing portion 32 and the inner surface 33a of the parallel portion 33 face each other and are spaced apart from each other. The opposing part which accommodates the extension part 36 is comprised.

  In addition, the metal fitting 19 has the tip 32b of the facing portion 32 bent toward the inside of the fixed portion 31, and the orthogonal portion 38 of the drawer fitting 29 that makes contact with each other tends to shift upward. Can be limited. For this reason, it is avoided that the drawer fitting 29 is inadvertently detached from the receiving fitting 19 and the front panel 21 is dropped.

  Further, the lead metal fitting 29 is bent to a thickness about the thickness of the end portion 36b on the other end side of the extending portion 36 in the direction toward the orthogonal portion 38, and the inner surface of the front end portion 36b is received by the facing portion of the metal fitting 19 The orthogonal portion 38 can be brought into contact with the facing portion 32 while being displaced in sliding contact with the end side 32a of the 32. For this reason, the drawer fitting 29 can stabilize the state in which the front panel 21 is separated from the front side opening 11a of the housing 11 and the orthogonal portion 38 is opposed to the facing portion 32 of the receiving bracket 19. The front panel 21 can be stably held. Further, when the front panel 21 is brought close to the front opening 11 a of the housing 11, the drawer fitting 29 is slidably brought into contact with the parallel portion 33 of the receiving fitting 19 from the bent surface on the distal end side of the extending portion 36. I can guide you.

  Accordingly, the studio single device 10 is inserted between the facing portion 32 and the parallel portion 33 of the metal fitting 19 so that the extension portion 36 of the drawer metal fitting 29 is slidable, and the front panel 21 is placed in front of the housing 11. The side opening 11a can be approached and closed.

  On the other hand, when operating the power switch 14, the extended portion 36 of the drawer metal fitting 29 is guided and slid between the facing portion 32 and the parallel portion 33 of the metal fitting 19, and the front panel 21 is pulled forward to pull out the housing 11. It can be separated from the front side opening 11a, and can be sufficiently separated to the extent that the orthogonal portion 38 of the drawer fitting 29 is abutted against the facing portion 32 of the receiving fitting 19.

  At this time, the facing portion 32 of the receiving bracket 19 and the orthogonal portion 38 of the drawer fitting 29 function as a stopper that restricts the front panel 21 from being pulled out more than necessary, and an excessive load (tensile stress) is applied to the flat cable 24. It can avoid giving and damaging. In addition, the receiving bracket 19 and the drawer fitting 29 can maintain the state in which the facing portion 32 and the orthogonal portion 38 are hooked while facing each other, and the front panel 21 is inadvertently released even if the hand is released. It can be held in a stable state without falling off.

  Further, the front panel 21 can be easily and easily detached from the receiving metal fitting 19 by simply moving the front panel 21 upward, and can be easily removed from the housing 11 as required.

  As described above, according to this embodiment, the receiving metal 19 is fixed in the front-side opening 11 a of the housing 11 and the drawer metal 29 is fixed on the back side of the front panel 21. Can be smoothly slid to open and close the front-side opening 11a of the housing 11, while the front panel 21 can be prevented from being damaged by pulling or dropping the front panel 21. . Further, it can be easily removed from the housing 11 simply by pulling the front panel 21 upward.

  Further, as another first aspect of this embodiment, as shown in FIG. 5, the extended portion 36 of the drawer metal fitting 29 has a base end portion 41 side where the fixing portion 37 is provided continuously to the main body portion 42 side. On the other hand, a structure may be adopted in which the rotary shaft 43 is pivotally connected. In this case, in the above-described embodiment, the extended portion 36 of the drawer metal fitting 29 rises in accordance with the posture of the front panel 21 and separates from between the facing portion 32 and the parallel portion 33 of the receiving metal fitting 19. However, the main body 42 rotates with its own weight relative to the base end 41 and falls. For this reason, a change in the posture of the front panel 21 is absorbed to some extent, and the extended portion 36 of the drawer metal fitting 29 is located between the facing portion 32 and the parallel portion 33 of the receiving metal fitting 19 and is maintained in an engaged state. Can do.

  As another second aspect of this embodiment, as shown in FIG. 6, the metal fitting 19 is formed in the same shape at a position facing the opposite side of the facing portion 32 instead of the parallel portion 33. The facing portion 52 that functions in the same manner may be formed, and the drawer fitting 29 may be formed with an orthogonal portion 58 that extends to the opposite side of the orthogonal portion 38 of the extending portion 36 and functions similarly in the same shape. . In this case, since the facing portions 32 and 52 of the receiving bracket 19 exist at opposite positions on both sides of the extending portion 36 of the drawer fitting 29, it is possible to restrict the drawer fitting 29 from being shifted left and right. In addition, the orthogonal portions 38 and 58 of the drawer metal fitting 29 can be simultaneously faced and stopped and held in a stable state.

  As another third aspect of this embodiment, as shown in FIG. 7, instead of the receiving metal fitting 19, a receiving metal fitting 61 is fixedly provided on the side surface 11 c of the front side opening 11 a of the housing 11, while the drawer fitting 29 is provided. Instead, a drawer fitting 65 is fixed on the back side of the front panel 21. The metal fitting 61 is formed in a step shape, and includes a fixing portion 62 fixed to the side surface 11c side of the housing 11 and a receiving portion 63 that is bent upward from the fixing portion 62 and then extends upward. I have. The drawer metal fitting 65 has a bar-like extension part 66 extending so as to replace the extension part 36 of the drawer metal fitting 29, and an orthogonal shape in which the tip of the extension part 66 is bent in the orthogonal direction so as to change to the orthogonal part 38. A portion 68 and a fixing portion 67 which is connected to the base end side of the extending portion 66 and bends in the orthogonal direction, is formed in a flat plate shape and is fixed to the back side of the front panel 21. Further, the receiving portion 63 of the receiving metal fitting 61 has a lower side (fixed portion 62 side) on the back side of the front side opening 11a and has an oblique side 63a, and a tip end portion 63b extends from the side surface 11c of the front side opening 11a. It bends in the direction of separation and widens the opening side.

  In this case as well, as in the above-described embodiment, the extending portion 66 of the drawer fitting 65 is opened largely upward between the receiving portion 63 of the receiving fitting 61 and the side surface 11c of the front opening 11a. It can be made into the engagement state which inserts and accommodates easily. In this state, the drawer fitting 65 is freely slidably moved in the direction of approaching / separating toward the front-side opening 11a of the housing 11 while being received and guided by the extending portion 66 and the receiving portion 63 of the fitting 61. The front panel 21 can slide in a direction to open and close the front side opening 11a of the housing 11. On the other hand, when the front panel 21 is separated from the front-side opening 11 a of the housing 11 by the length of the extending portion 66, the orthogonal portion 68 of the drawer fitting 65 is on the oblique side 63 a side of the receiving portion 63 of the receiving fitting 61. It is stopped and further slide and upward movement are restricted. Further, the drawer fitting 65 can be easily detached from the upper opening side of the receiving portion 63 of the receiving fitting 61 by moving the extending portion 66 upward perpendicular to the opening and closing direction, and the front panel 21 can be removed. The casing 11 can be easily removed from the front side opening 11a. Accordingly, even with such a simple structure, similarly, it is possible to avoid that the drawer fitting 65 is inadvertently detached from the receiving fitting 61 and the front panel 21 is dropped.

  As described above, the embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. However, it is included in this invention. For example, the present invention is not limited to a single studio device in which a power switch is provided in the opening on the front side of the housing, and may be an electronic device in which another switch is provided, or simply constructed so that the front panel can be attached and detached. It can also be applied to electronic devices.

  The present invention is not limited to a single studio device installed in a shelf in a studio of a broadcasting office, but can be widely applied to other electronic devices, and is not installed in a shelf. The present invention can also be applied to an electronic device mounted on the apparatus and an electronic device used independently.
