Description

  The present invention relates to an opening / closing door for a media slot, and more particularly, to a locking mechanism for an opening / closing door having a hinge structure.

  Many electronic devices such as paperless recorders and personal computers that collect data from field devices have media slots for exchanging data with portable recording media. In general, a cover is attached to the media slot from the viewpoint of dust prevention and design, and an open / close door having a hinge structure is widely used as a cover of the media slot.

  18A and 18B are external views of a conventional paperless recorder provided with an opening / closing door. FIG. 18A shows a state where the opening / closing door is closed, and FIG. 18B shows a state where the opening / closing door is opened. ing.

  As shown in FIG. 18A, the paperless recorder 30 includes a main body 300, a display 310, a front cover 320, an open / close door 330 having a hinge mechanism 331, a push-down knob 332, and operation keys 340. When the push-down knob 332 is operated, the hinge mechanism 331 opens the opening / closing door 330 as shown in FIG. 18B, and the media slot 350 is exposed.

  Although the media slot 350 can be accessed by opening the opening / closing door 330, it is not preferable that the media slot 350 can be freely accessed from the viewpoint of security of recorded data.

  Therefore, Patent Document 1 proposes to add a lock mechanism to the open / close door 330. According to the invention described in Patent Document 1, as shown in FIG. 19, the opening / closing door 330 is provided with a lock plate 333 having a structure for preventing the knob 332 from being pushed down depending on the rotation direction. The lock plate 333 has a shape in which levers are provided on both side surfaces of a disc that rotates on a horizontal plane.

  If the knob 332 cannot be pushed down by the rotation operation of the lock plate 333, the opening / closing door 330 cannot be opened, and the opening / closing door 330 is locked. The lock plate 333 is rotated by inserting a thin rod into a pin hole (not shown).

JP 2007-47061 A

  In the invention described in Patent Document 1, it is possible to restrict free access to the media slot 350 by operating the lock plate 333 in a locked state when the paperless recorder 300 is not used. However, since a space for rotating the lock plate 333 on a horizontal plane is required, the opening / closing door 330 is required to have a certain thickness.

  In recent years, the thickness of the main body tends to increase due to the increase in functionality and multifunction of the paperless recorder 300. In particular, when a touch panel function is added to the display, the thickness increases accordingly. On the other hand, since there is a demand for downsizing and it is necessary to realize a size that can be replaced with a conventional model, it is desirable that the door 330 is thinner.

  Therefore, an object of the present invention is to achieve both maintenance of thinness and a locking mechanism in an opening / closing door of a media slot.

In order to solve the above-described problems, an opening / closing door of a media slot according to the present invention includes an opening / closing door base having a hinge mechanism, and an opening / closing door cover slidable in a first direction with respect to the opening / closing door base. The door cover includes a fixed-side latch formed on a member on the media slot side, a movable-side latch that meshes in the first direction, and a protrusion formed in the vicinity of the movable-side latch. A concave portion corresponding to the protrusion is formed on one side, and a slide plate is provided that is slidable in a direction orthogonal to the first direction so that the side can be switched between a position in contact with the protrusion and a position not in contact with the protrusion. It is characterized by being.
Here, the open / close door base includes an open / close door base side slot into which a security lock can be inserted, and the slide plate is located on the side of the slide plate that overlaps the open / close door base side slot at a position where the one side contacts the protrusion. A slot may be formed.
In addition, the hinge mechanism portion may include a hinge pin formed with an inclination that is lowered toward a direction in which the hinge mechanism portion is fitted to the member on the media slot side in the closed state.

  According to the present invention, it is possible to achieve both maintenance of thinness and a locking mechanism in the opening / closing door of the media slot.

  Embodiments of the present invention will be described with reference to the drawings. Although this embodiment demonstrates the case where the opening / closing door of this invention is applied to a paperless recorder, this invention is not restricted to a paperless recorder, It applies to the various electronic devices provided with the opening / closing door which covers a media slot. Can do.

  FIG. 1 is a diagram illustrating an appearance of a paperless recorder according to the present embodiment. As shown in the figure, the paperless recorder 10 includes a main body 100, a touch panel display 110, a front cover 120, an opening / closing door 130 having a hinge mechanism 131, a security slot 132, a menu key 140, and a knob 161.

  Here, the security slot 132 is a slot into which a general-purpose L-shaped or T-shaped security lock can be attached, and the door 130 cannot be completely opened by inserting and locking the security lock. The security slot 132 can take two states: a state in which a security lock can be inserted (locked state) and a state in which a security lock cannot be inserted (unlocked state). The structure of the security slot 132 will be described later.

  FIG. 2 is a view showing a state in which the opening / closing door 130 is opened by the hinge mechanism 131. As shown in this figure, when the door 130 is opened, the power switch 141, the media slot 142, and the start / stop key 143 are exposed. The menu key 140 passes through the opening / closing door 130 and can be operated even when the opening / closing door 130 is closed.

  On the other hand, the power switch 141 and the start / stop key 143 can be operated only when the door 130 is opened. The power switch 141 is a switch for controlling on / off of the power source, and the start / stop key 143 is a switch for instructing start / stop of data collection, both of which are important from the viewpoint of security of recorded data. Of course, the media slot 142 cannot be accessed unless the door 130 is opened.

  As shown in FIG. 3A, the open / close door 130 includes an open / close door base 150 and an open / close door cover 160. As shown in FIG. 3B, the open / close door cover 160 can slide up and down with respect to the open / close door base 150. Since it slides on a vertical plane, the door 130 can be designed to be thin.

  The opening / closing door cover 160 is normally stable at an upper position by a spring mechanism (not shown) and a guide for restricting movement, and the entire opening / closing door cover 160 moves downward only during a period in which the knob 161 is pressed downward. When the door cover 160 is stable upward, the upper sides of the door cover 160 and the door base 150 are almost aligned, and the moving distance of the door cover 160 when the knob 161 is pushed down is sufficient. . Specifically, it is sufficient that the distance is such that the later-described latch engagement is released.

  The open / close door base 150 includes a hinge pin portion 151 and an open / close door base side slot 152. The hinge pin portion 151 constitutes a part of the hinge mechanism 131, and the open / close door base side slot 152 constitutes a part of the security slot 132.

  FIG. 4 is a view showing the back surface of the open / close door cover 160. As shown in the figure, a movable side latch 162 having a meshing surface on the upper side is formed on the back surface of the door cover 160. As shown in FIG. 5, the movable side latch 162 moves up and down with respect to the door base 150 as the door cover 160 slides up and down by the operation of the knob 161.

  As shown in FIG. 6 schematically showing the engagement surface of the movable side latch 162 from the lateral direction, a fixed side latch 121 having an engagement surface on the lower side at a position corresponding to the movable side latch 162 of the front cover 120. Is formed.

  The fixed side latch 121 is configured such that when the door 130 is closed, the sliding state of the door cover 160 is engaged with the movable side latch 162 in a normal state so that the door 130 does not open in this state. It has become.

  When the door cover 160 is slid downward by operating the knob 161, the meshing state between the fixed side latch 121 and the movable side latch 162 is released, and the door 130 is opened by pulling the knob 161 forward. be able to. Since the movable side latch 162 is inclined, it is sufficient to push the door 130 toward the front cover 120 when closing the door 130.

  An opening / closing door protrusion 163 is provided below the movable side latch 162 of the opening / closing door cover 160. As shown in FIG. 7, a plurality of opening / closing door protrusions 163 can be provided. As described later, the opening / closing door protrusion 163 has a function of suppressing downward sliding of the opening / closing door cover 160 in a locked state, and a movable side latch 162 is provided. It also has a function to reinforce.

  Next, the lock mechanism of the door 130 will be described with reference to FIG. As shown in this figure, the open / close door base 150 is provided with a slide plate 170, and can be slid left and right by operating a slide plate operation unit 178. The slide plate 170 is disposed below the movable side latch 162 of the open / close door cover 160 so that the upper side of the slide plate 170 is in contact with the lower end of the open / close door protrusion 163. Since the slide plate 170 slides on the vertical plane, the open / close door 130 can be designed to be thin.

  FIG. 9 is a view showing the slide plate 170. As shown in the figure, the slide plate 170 includes a V-shaped slide plate cutout portion 172 and a slide plate side slot 171 formed on the upper side on a straight line. The slide plate side slot 171 constitutes a part of the security slot 132 and overlaps the opening / closing door base side slot 152, so that the security slot 132 can be inserted with a security lock.

  It is assumed that the number of the slide plate cutouts 172 matches the number of the opening / closing door protrusions 163 provided at the lower part of the movable side latch 162 of the opening / closing door cover 160. In addition, the interval between the slide plate notches 172 is set to the interval between the opening and closing door protrusions 163.

  As shown in FIG. 10A, when each slide plate notch 172 is in a position corresponding to each opening / closing door projection 163, the slide plate 170 does not interfere with the opening / closing door projection 163. Can slide down. That is, the open / close door 130 is unlocked, and the open / close door 130 can be opened by operating the knob 161.

  On the other hand, when the slide plate 170 is slid sideways and the slide plate notch 172 is shifted from the opening / closing door projection 163 as shown in FIG. The door protrusion 163 comes into contact with the door, and the door cover 160 cannot be slid downward. That is, the open / close door 130 is locked, and the open / close door 130 cannot be opened.

  The slide plate side slot 171 and the open / close door base side slot 152 overlap each other at the position of the slide plate 170 where the open / close door 130 is locked, and the security slot 132 can be inserted into the security lock.

  Therefore, by inserting a security lock into the security slot 132 and locking it, the locked state of the door 130 is held by the security lock. As a result, the security of the recording data becomes robust. Further, by connecting the security lock to the fixed equipment, the paperless recorder 10 itself can be prevented from being stolen.

  The slide movement of the slide plate 170 can be performed by operating a slide plate operation unit 178 that holds the slide plate 170, as shown in FIG. The slide operation of the slide plate operation unit 178 can be performed on the bottom surface 153 of the door base 150 as shown in FIG.

  As described above, the paperless recorder 10 of the present embodiment can make the opening / closing door 130 thinner because the opening / closing door 130 can be locked by the lateral movement of the slide plate 170. That is, the maintenance of the thinness of the door 130 and the lock mechanism are compatible.

  The locked state by the slide plate 170 is stronger and more reliable than the state in which the fixed side latch 121 and the movable side latch 162 are engaged with each other. For example, in MEMA4 which is an American standard, water of 250 L / min is applied as a waterproof test, but the locked state by the slide plate 170 can withstand this impact.

  Furthermore, by holding the locked state by the slide plate 170 with the security lock, only the person who can unlock the security lock can open the door 130. As a result, the recording data and the recording medium are surely protected.

  Note that the slide plate notch 172 of the slide plate 170 is not limited to the V shape, and may be various concave shapes as illustrated in FIG. Further, as shown in FIG. 13B, the slide plate 170 is formed in a disc shape having a notch 172 in a part of the circumference, and the slide operation of the slide plate operation unit 178 is converted into rotation of the slide plate 170. With such a rack-and-pinion structure or the like, the state in which the circumference of the slide plate 170 is in contact with the opening / closing door protrusion 163 may be switched. Also in this case, the slide plate-side slot 171 is formed in the slide plate 170 so that the security slot 132 can be inserted with the security lock while the circumference of the slide plate 170 is in contact with the opening / closing door protrusion 163. To do.

  Moreover, although this embodiment demonstrated the case where the hinge mechanism 131 was formed below the door 130, this invention is applied also when the hinge mechanism 131 is formed above the door 130, and right and left. can do.

  By the way, even if the lock state of the door 130 by the slide plate 170 is strong, if the hinge mechanism 131 seems to be easily removable, the meaning of the lock state is lost. On the other hand, considering productivity, the assembly of the hinge mechanism 131 is also required to be easy.

  For example, if a shaft hinge with a metal shaft passing between the left and right sides of the door 130 is used, sufficient strength of the hinge mechanism 131 can be obtained. However, the assembly is not easy, and the shaft is connected to the slide plate 170 and the slide plate operation unit 178. It is difficult to employ a shaft hinge because of interference. In addition, in the configuration in which one hinge is a fixed pin and the other hinge is a movable pin that sinks with a spring, assembly is easy, but it can be easily removed.

  Therefore, the hinge mechanism 131 of the paperless recorder 10 of the present embodiment has a structure in which the hinge pin portion 151 of the open / close door 130 is fitted into the hinge hole portion 122 provided in the front cover 120 as shown in FIG. The hinge pin part 151 and the hinge hole part 122 are inclined one way. This structure is common to the left and right. At the time of assembly, as shown in the figure, the door 130 can be easily assembled because it can be pushed toward the front cover 120 in the closed state. FIG. 15 is an enlarged view of the hinge mechanism 131.

  As shown in FIG. 16, the hinge pin portion 151 of the open / close door 130 is formed with an inclination that goes down in the direction A in which the hinge pin portion 151 is fitted to the front cover 120 in the closed state. In addition, as shown in FIG. 17, the hinge hole portion 122 of the front cover 120 is formed with an inclined surface that descends in the direction B in which the hinge hole portion 122 is fitted to the open / close door 130.

  At the time of assembly, the opening / closing door 130 is set in the closed state so that the inclined surface formed in the hinge pin portion 151 and the inclined surface formed in the hinge hole portion 122 are in smooth contact with each other, so that the hinge pin portion 151 and the hinge The fitting with the hole 122 can be easily performed.

  After assembly, when the open / close door 130 is closed, the opposite side of the inclined surface of the hinge pin portion 151 and the wall of the hinge hole portion 122 are in contact with each other, and thus cannot be easily removed. For this reason, it is possible to prevent the hinge mechanism 131 from being removed in the locked state in which the open / close door 130 is closed.

  When the open / close door 130 is open, a part of the slope of the hinge pin portion 151 and the wall of the hinge hole portion 122 are in contact with each other, which makes it somewhat easier to remove, but when the open / close door 130 is open, the open / close door is opened. Even if 130 is removed, there is no problem with the security of the recorded data.
