  For example, in the case of equipment that is considered to be upgraded, it is conceivable that at each upgrade, the customer separates a part of the equipment from the main equipment and replaces the internal substrate. The requirement is that the customer can perform the exchange operation, and the separation operation is smooth, and there is work in a situation where the work space is not sufficiently secured, so it is difficult to use a tool with a large or long tool. Even if a special tool is used, if the operation parts are exposed to the outside of the equipment, there is a high possibility that the equipment will be attracted by the customer and receive some operation, and the equipment will be separated against the design intention. It can also cause unnecessary accidents.

  The present invention has been made in view of the above-described problems, and is provided with a lock mechanism that couples a part of a device to a main device so that the user does not operate, so that a component that triggers the release of the lock mechanism is not exposed. It is an object of the present invention to provide a device attachment / detachment device that is loaded inside the device and uses a small magnet for the tool used for the unlocking operation.

  The present invention is an apparatus for attaching and detaching a device comprising a first housing and a second housing, wherein the first housing includes an outer housing into which the second housing can be inserted, and the outer housing Is compressed by insertion of a start plate having a hook for coupling the second housing and a monopolar magnet for unlocking the hook and the second housing, and the second is released when the hook is unlocked. A spring for pushing the housing is provided, and the lock of the hook is released by generating a repulsive force on the magnet of the starting plate from the outside.

  According to the present invention, when a repulsive force is applied to the magnet of the starter plate inside the outer casing by a magnet or the like from the outside, the starter plate operates and the hook is unlocked. It is separated from the outer casing provided in the casing. Since the user who is not informed of this separation method cannot separate the second casing, unnecessary accidents can be prevented from being induced.

  Since the start plate for releasing the lock of the hook is not exposed to the outside of the device, the serviceability is improved and the design is improved without being touched by the user easily. No special tool is required because the repulsive force of the magnet is used when unlocking. Since the strength of the repulsive force depends on the magnetic force of the magnet used as a tool, it can be adjusted by selecting the magnetic force, and can be configured without relying solely on the holding force of the magnet in the device. When the second casing is coupled to the first casing, it can be completed simply by fitting into the outer casing provided in the first casing without using any special tool. Since there is a starter plate between the hook and the second housing, it is possible to reliably perform the detachment operation. Since an electric drive device such as a motor or solenoid is not used, it is advantageous in reducing the power supply capacity, generating no noise, and securing the volume.

  A device attachment / detachment device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a casing of a video signal processing apparatus (hereinafter, equipment) having a top box to which the present invention is applied, FIG. 2 is a perspective view showing a top box inner case and an outer case, FIG. 4 and 5 are a perspective view, a rear view, and a side view showing a configuration of a main part between the inner case and the outer case of the top box with a part of the outer case omitted, and FIG. The side sectional view showing the state of a hook trip board is shown.

  The device 1 includes a base box (first housing) 10 and a top box (second housing) 20, and the base box 10 includes an outer case 30 for detachably attaching the top box 20 to the upper portion. ing. A top box (hereinafter referred to as an inner case) 20 mounted in the outer case 30 has a structure that can be fitted into the outer case 30 from the front, and the inner case 20 is fitted in the outer case 30. The front surface of the inner case 20 is aligned with the front surface of the base box 10 (FIG. 1).

  The base box 10 and the top box (inner case) 20 incorporate a signal processing board therein. When the inner case 20 is fitted into the outer case 30 attached to the upper part of the base box 10, the inner box 20 The connector is electrically connected by a connector between the case 20 and the outer case 30 (not shown).

  The inner case 20 includes an inner case main body 21 and a front panel 22. The inner case main body 21 is made of a non-magnetic material (for example, aluminum material), and the outer width is formed smaller than the inner width of the outer case 30 so as not to hit the starter plate 41 provided in the outer case 30. Is formed slightly lower than the inner height of the outer case 30 so that the hook releasing plate 43 of the starter plate 41 can move along the upper surface of the inner case main body 21. The upper wall 23 of the inner case main body 21 is formed with a hook hook hole 26 with which a hook 36 of a hook plate 35 formed in the outer case 30 can be engaged.

  The outer case 30 is made of a non-magnetic material (for example, aluminum material), and a hook plate 35 is formed on the upper wall 31 of the outer case 30 by a notch 34 so that the hook plate 35 can be bent in the vertical direction. A hook 36 having a tapered surface 36a on the lower surface is formed. A start plate 41 for removing the hook 36 of the hook plate 35 engaged with the hook hole 26 of the inner case 20 is provided inside the side wall 32 of the outer case 30. Inside the wall 33, there is provided an extrusion spring 51 that is pressed by the rear wall 25 of the inner case 20 and pushes the inner case 20 forward when the hook 36 of the hook plate 35 is removed.

  The starting plate 41 includes a left and right arm 42 made of a leaf spring material, and a hook release plate formed on the upper edge of the movable end of the arm 42 and positioned on the upper surface of the hook hooking hole 26 portion of the inner case 20. 43 and a monopolar magnet 44 provided on the outer surface of the movable end of the arm 42, and the base of the arm 42 is attached to the inside of the side wall 32 of the outer case 30 via the spacer 45, and the permanent magnet 44 Is positioned in the vicinity of the inner surface of the side wall 32 of the outer case 30, and when a magnetic force having the same polarity is applied to the magnet 44 from the outside of the outer case 30, the movable end 42a of the arm 42 is moved inward by the repulsive force. It is. The hook trip plate 43 has a substantially right triangle shape, and the rear side is a hypotenuse 43a.

  Below, the operation | movement of attachment / detachment with respect to the outer case 30 of the inner case 20 is demonstrated. First, an operation when the inner case 20 is inserted and coupled to the outer case 30 will be described. In the state where the inner case 20 is separated from the outer case 30, the starting plate 41 provided in the outer case 30 has its magnet 44 positioned in the vicinity of the inner surface of the side wall 32 of the outer case 30, and the hook release plate. The distal end portion of 43 is located below the distal end of the hook plate 35 so that the hook 36 is not pushed upward, and the distal end portion 36 b of the hook 36 is projected downward from the lower surface height position of the hook trip plate 43. There is a state (the inner case 20 is removed from FIG. 6A).

  The inner case 20 is inserted into the outer case 30 in the above state from the front. When the rear part of the inner case 20 enters the outer case 30, the rear upper edge 23a slides the taper part 36a on the lower surface of the hook 36 to warp the hook plate 35 upward, and then warps the hook plate 35 upward on the upper surface of the inner case 20. Then, the rear wall 23 of the inner case 20 compresses the pushing spring 51. At the same time as or immediately before the rear surface 21a of the front panel 21 of the inner case 20 abuts the front end of the outer case 30, the hook 36 of the hook plate 35 warped upward on the upper surface of the inner case 20 is And the hook plate 35 is no longer warped and is locked. In this locked state, since the inner case 20 is urged forward by the compressed pushing spring 51, the hook 36 is pushed forward by the rear edge 26a of the hook hooking hole 26, so that the inner case 20 is 30 (FIG. 6 (A)).

  Next, the operation when separating the combined inner case 20 from the outer case 30 will be described. A magnetic force that generates a repulsive force is applied to the magnet 44 from the outside of the device 1 toward a position where the magnet 44 of the starter plate 41 is located. For example, a magnet M (not shown) having the same polarity as the magnet 44 is opposed to the magnet 44 from the outside of the device. The magnet 44 transmits a repulsive force with the magnet M to the starting plate 41. As a result, the arm 42 of the starter plate 41 warps to the inner case 20 side, the hook tripping plate 43 of the starter plate 41 slides on the upper surface of the inner case 20, and the oblique side 43a of the rear part slides the taper part 36a of the hook 36 and moves the hook 36. The hook plate 35 is pushed up and warped upward, and the hook 36 is removed from the hook hook hole 26 of the inner case 20 (FIG. 6B). When the hook 36 is removed from the hook retaining hole 26, the inner case 20 biased by the pushing spring 51 moves forward by the force of the pushing spring 51, and the hook hanging hole 26 of the inner case 20 moves forward from the position where the hook 36 is located. The unlocking lock is completely released. When the initial repulsive magnetic force of the magnet 44 decreases, the starting plate 41 returns to the steady position by its own spring force. The inner case 20 that has moved forward is pulled out and separated from the outer case 30 by hand.

  According to the above-described embodiment, the inner case 20 can be coupled to the outer case 30 simply by inserting and pushing the inner case 20 into the outer case 30, and the magnet 44 of the starter plate 41 located inside by an external magnet. By applying a repulsive force, the hook 36 is unlocked and the inner case 20 can be separated. The release of the lock is configured such that the oblique side 43a of the hook trip plate 43 slides on the taper portion 36a of the hook 36 to release the lock of the hook 36, and the force applied to the hook trip plate 43 can be small. If the starter plate 41 is formed to be easily warped, the lock can be reliably released even if the repulsive force of the magnet 44 is not so large.

  In the above embodiment, the inner case 20 is inserted / drawn without using a rail / slide. However, since the start plate 41 is provided in the outer case 30, the guide rail guides the inner case 20 to the outer case 30. Etc. are desirable. Moreover, although the starter plate 41 is provided on both sides, it can be provided on only one side.
