Description

  The present invention relates to a traffic control terminal device that is installed on a column or the like disposed on an outdoor road and houses a circuit board that performs various processes in a traffic control system. In particular, the present invention relates to a traffic control terminal device suitable for accommodating a plurality of relatively large circuit boards while having a small casing body.

  Conventionally, traffic control systems have been widely constructed in order to efficiently manage and control traffic conditions. This system includes traffic control devices such as traffic lights and vehicle detectors arranged on the road side outdoors, and a traffic control center that performs management control of traffic conditions in a centralized manner using data from these devices. The traffic control center collects data from traffic control equipment such as traffic lights, and performs processing such as determining appropriate traffic signal control data based on these data and transmitting new control data to traffic lights With central processing unit. Data transmission / reception between the central processing unit and the traffic control device is usually performed via a terminal device having a communication circuit board accommodated on the road side.

As a conventional terminal device, for example, there is a configuration shown in FIG. Inside the terminal device, it comprises a box-like housing body c having a rectangular opening c _o, and an outer door o for opening and closing the opening c _o of the housing body c, the housing body c The rectangular circuit board b is accommodated in the space. Housing body c comprises a open surface opening c _o is made, and four side surfaces c _s orthogonal to the opening surface, is formed in the back c _b opposite the open face, generally, the short side of the opening surface It is installed vertically so that the horizontal direction and the long side are vertical. The circuit board b is usually housed so that the mounting surface b _f on which the circuit is formed faces the opening _co side of the housing body c, that is, parallel to the opening surface. The back surface of the circuit board b, comprises a connector wires w ₁ is connected (not shown). The wiring w _1, the wiring w ₂ to be connected to devices such as traffic control center of the central processing unit and the signal unit is connected via a connection terminal unit t. This connection enables data transmission / reception between the central processing unit and the traffic light. In addition, a power supply line (not shown) is connected to the circuit board b.

In addition, when the terminal device is inspected, repaired, or exchanged, the circuit board is charged by static electricity charged to the operator when the operator opens the outer door and immediately contacts the circuit board. Since the inner door i is provided on the back side of the outer door o, the operator first touches the inner door i after opening the outer door o. Each of the outer door o and the inner door i is pivotally supported on the housing body c by the vertical rotation shafts h ₁ and h ₂ whose axial direction is the vertical direction, and as shown by an arrow in FIG. Is a side-opening door that opens and closes by rotating in the left-right direction (horizontal direction) in a state where it is installed on a column or the like (the state shown in FIG. 8).

  As another terminal device, there is a configuration in which an antistatic panel is directly attached to a mounting surface of a circuit board without providing an inner door (see Photo 2 of Non-Patent Document 1). Further, the transmitter described in Patent Document 1 is configured to include a cover so as to cover the entire surface of the circuit board (see Patent Document 1 and FIG. 2). In these terminal devices and transmitters, static electricity can be released by the operator first touching the panel or cover.

  Moreover, in the terminal device and transmitter which do not provide the said inner side door, the circuit board is accommodated as follows. First, in the terminal device shown in Non-Patent Document 1, as in the terminal device shown in FIG. 8, the circuit board is accommodated so that the mounting surface of the circuit board is parallel to the opening surface of the housing body. In the transmitter shown in Patent Document 1, the circuit board is accommodated so that the mounting surface of the circuit board is parallel to the side surface, not the opening surface of the housing body, that is, the side surface of the circuit board is parallel to the opening surface. .

  Conventional terminal devices have been mainly used for data transmission / reception as described above. However, in recent years, not only data transmission / reception, but also sensing processing such as calculation, determination, and comparison based on data from a vehicle detector. In addition, it has been demanded to perform many processes such as performing a traffic signal control process based on the result, or performing a vehicle detector or traffic signal control process based on data from the central processing unit. Therefore, in the conventional terminal device, it suffices to have one relatively small circuit board. However, in recent years, since the circuit board has become larger and more and more are required, such a large circuit board is required. Development of a terminal device that can accommodate a plurality of devices is desired.

  In order to accommodate a plurality of large circuit boards, it is easiest to make the casing body thick and large. However, in recent years, in order to improve the aesthetics, the housing body of the terminal device tends to be reduced in size and thickness, and a configuration that can accommodate a plurality of larger circuit boards in a small and thin housing body is desired.

  In the transmitter of Patent Document 1, a plurality of circuit boards such as a data processing unit, a data signal modulation unit, and a high frequency unit are stacked and stored so that the mounting surface is parallel to the side surface of the housing body. By stacking circuit boards in this way, a plurality of circuit boards can be stored. However, since the casing body usually has a larger area on the opening surface than on the side surface, it is difficult to store a circuit board having a large mounting surface in this storage format. In particular, it is more difficult to accommodate a circuit board having a larger mounting surface in consideration of thinning of the casing body. Further, in the case of a configuration in which the entire surface of the circuit board is covered with a cover as in the transmitter of Patent Document 1, the presence of the cover further reduces the storage capacity of the circuit board in the housing body. In addition, since it is covered with the cover in this way, when maintenance such as repair or replacement is performed, the cover must be removed, and workability is not good.

  Therefore, a main object of the present invention is to provide a traffic control terminal device capable of storing a plurality of circuit boards in a smaller casing body. Another object of the present invention is to provide a traffic control terminal device that is excellent in maintenance workability.

The present inventor has made various studies on a storage format that can store a plurality of circuit boards. In the type in which the mounting surface b _f of the circuit board b is stored so as to be parallel to the opening surface of the housing body c as in the terminal device of FIG. 8, a circuit board having a large mounting surface can be stored. In order to store a plurality of circuit boards in this storage format, as shown in FIG. 9, the circuit boards b _{1 to} b ₃ are provided with a connector b _con on the mounting surface b _f and the opposite surface, and the circuit boards are connected to each other. It can be considered that a plurality of circuit boards b _{1 to} b ₃ are stacked and stored so that the mounting surface b _f is overlaid. With this storage format, a plurality of large circuit boards can be stored. Further, since the circuit boards b ₁ and b ₂ are connected to the circuit board b ₃ via the connector b _con, and thus connected to the wiring w ₁ to which the connector con is attached via the circuit board b ₃ , Data transmission is possible. However, this storage type has a problem that workability is not good when performing maintenance such as inspection, repair, and replacement. The circuit board b ₁ arranged on the front side (opening c _o side) of the housing body c can be easily repaired because the mounting surface b _f is visible when the inner door is opened. However, the circuit board b ₂ and the circuit board b ₃ arranged on the back side (rear side c _b side) of the casing body c are the circuit boards b ₁ and b ₃ arranged in front of the circuit boards b ₂ and b ₃ . since the mounting surface b _f is hidden by b _2, when performing such repairs must remove the circuit board b _1, b _2. And the circuit board arrange | positioned in the back | inner side of a housing | casing main body is hard to perform the operation | work taken out from a housing | casing main body.

  On the other hand, the terminal device of Non-Patent Document 1 also accommodates a circuit board having a large mounting surface because the mounting surface of the circuit board is parallel to the opening surface of the housing body, similarly to the terminal device of FIG. can do. However, this terminal device has a configuration in which the panel is directly attached to the mounting surface of the circuit board without providing an inner door. Therefore, when storing a plurality of circuit boards, the circuit board to which the panel is attached is the frontmost of the housing body. It is necessary to store the circuit board so as to be disposed on the side (opening side). Then, as in the case of FIG. 9 above, connectors are provided on the mounting surface of each circuit board and the opposite surface thereof to connect the circuit boards, and the circuit boards are laminated so that the circuit board having the panel is on the opening side. As in the case of FIG. 9, improvement in maintenance workability is desired. Moreover, when inspecting, repairing, or replacing a circuit board having a panel, it is necessary to remove the panel, which is troublesome.

In order to store a circuit board having a large mounting surface in the housing body as described above, the mounting surface of the circuit board is placed on the opening surface of the housing body as in the terminal device of Non-Patent Document 1 or the terminal device of FIG. It is preferable to store in parallel. Therefore, in order to improve maintenance workability in this storage format, the present inventor provides connectors on the circuit board mounting surface and the back surface thereof to connect the circuit boards to each other and connect them to the wiring via one circuit board. instead of, it was investigated be connected by providing a connector b _con on an end face rather than the mounting surface c _f of the circuit board b as shown in FIG. 10, respectively wired to each circuit board b (not shown). In this configuration, when repairing or the like, after removing the laminated circuit board b from the housing body, only the necessary circuit board b can be pulled out of the circuit boards b. Therefore, the operator can perform maintenance work only on the circuit boards b ₂ and b ₃ without removing the circuit boards b ₁ and b ₂ arranged on the front side of the housing body.

However, for example, when the connector b _con is provided on the upper surface of the circuit board b, the circuit board b is pulled upward as shown by the upper arrow in FIG. 10, and the operator tries to perform the drawing work stably. Then, it is necessary to be at a position that is higher than the position where the outer door is opened by the drawing amount of the circuit board, which may not be preferable in consideration of safety. In particular, in recent years, it has been studied to attach the terminal device to a high place such as about 3 m, and it is not preferable from the viewpoint of worker safety to pull out the circuit board as described above. On the other hand, when the connector is provided on the lower surface of the circuit board, the operator can perform the drawing work at a relatively low position, but in this case, the circuit board may be dropped. On the other hand, when the connector is provided on the left end surface of the circuit board, the circuit board b is pulled out to the left as shown by the left arrow in FIG. 10, and the operator opens the outer door and the inner door of the housing body. From the position, the circuit board must be shifted to the left side by the drawing amount of the circuit board, which is not preferable in consideration of safety. In particular, as the mounting surface b _f of the circuit board b increases, the pulling margin increases and the danger increases. The same applies when the connector is provided on the right end surface of the circuit board.

  Furthermore, the present inventor has studied a configuration in which the circuit board is mounted on the back side of the inner door in order to facilitate removal of the circuit board from the housing body. The circuit board is mounted on the inner door by stacking the circuit boards so that the mounting surface of the circuit board is parallel to the opening surface of the housing body so that the circuit board having a large mounting surface can be stored in the housing body. I thought. However, in this type, since the load of the circuit board is applied to the inner door, when the number of circuit boards is increased, the hinge is distorted and the inner door may not be easily closed. In addition, as described above, when the connector is provided on the mounting surface of the circuit board or the opposite surface, it is difficult to perform maintenance work on the circuit board mounted on the inner door side among the stacked circuit boards. If it is provided on a surface other than the mounting surface such as the side surface or end surface of the circuit board, there is a problem in ensuring the safety of the operator.

As a result of the above studies, the present inventor has obtained the following knowledge.
1. When the circuit board is stored in the housing body, it is preferable that the mounting surface of the circuit board is arranged in parallel to the opening surface of the housing body because a relatively large circuit board can be stored.
2. When performing maintenance, it is preferable that the circuit board can be removed without removing it in the vertical direction or the horizontal direction.
3. Having an inner door is preferable because there is no need to remove it like an antistatic cover or panel attached to a circuit board.

  Based on the above findings, the inventor further configured the present invention as a result of further investigation to eliminate the problem when the circuit board is housed in the housing body and when the circuit board is detached from the housing body. It came to do. That is, according to the present invention, the circuit board is rotatably housed in the housing body so that the arrangement state of the circuit board can be changed between the housing body and the housing body when the housing body is housed and detached. This solves the above problem.

  That is, a terminal device for traffic control of the present invention includes a housing body having an opening surface, an outer door that opens and closes the opening surface, a rotating unit that is housed in the housing body and supports the circuit board in a detachable manner, A horizontal rotation shaft is provided parallel to the opening surface and rotatably supports the rotation unit with respect to the housing body. Hereinafter, the present invention will be described in more detail.

  The housing body is a box-shaped container having an opening surface, and has a space in which a rotating unit in which one or more circuit boards can be mounted can be stored. For example, a rectangular parallelepiped container formed by a rectangular front surface having an opening, a back surface facing the opening surface, and four side surfaces orthogonal to the front surface and the back surface can be mentioned. The opening may be all on the front surface or part of the front surface. In the present invention, the surface formed by the opening is defined as the opening surface. If the size of the opening is sufficiently larger than the mounting surface of the circuit board, the mounting surface of the circuit board can be stored so as to be parallel to the opening surface. As a material for forming the casing body and the outer door, since the terminal device of the present invention is disposed outdoors, a material having high strength and excellent corrosion resistance that can withstand severe environmental conditions such as exposure to wind and rain, for example, It is preferably formed of a material such as stainless steel with anticorrosion coating. In addition, when making an opening surface into a rectangular shape, this invention terminal device is normally installed vertically long so that the short side of an opening surface may become a horizontal direction and a long side may become a perpendicular direction.

  In the internal space of the housing body, in addition to the rotating unit described later, wiring connected to a connector provided on the circuit board, wiring connected to a traffic control device, central processing unit, etc., these wiring A connection terminal unit for connecting each other is stored.

  The opening of the housing body is opened and closed by the outer door, and is normally closed, and protects the circuit board housed in the housing body from wind and rain. Further, when the circuit board is stored or when maintenance such as inspection, repair, or replacement is performed, the circuit board is opened and the casing body is opened. The outer door may be formed of a plate-like material having a size that can sufficiently cover the opening of the housing body. Also, the outer door may be a so-called side-opening type that is supported by a vertical rotation shaft whose axial direction is the vertical direction so as to be rotatable with respect to the housing body, and is opened and closed by rotating in the left-right direction (horizontal direction). Alternatively, it may be a so-called vertical opening type that is pivotally supported with respect to the casing main body by a horizontal rotation shaft whose axial direction is the horizontal direction, and is opened and closed by rotating in the vertical direction (vertical direction). Further, when the outer door is closed, packing or the like may be disposed between the outer door and the casing main body so that the inside of the casing main body can be securely held airtight and watertight.

  In the terminal device of the present invention, the circuit board is not housed in the housing body as it is, but a rotating unit on which the circuit board can be mounted is housed so that the circuit board can be rotated. In the terminal device of the present invention, by rotating the rotary unit, the arrangement state of the circuit board, specifically, the orientation of the mounting surface can be changed, so that a larger circuit board can be mounted on the casing body or maintenance can be performed. At this time, the circuit board can be easily attached and detached.

  The rotation unit may be configured to include a circuit board and a support part that detachably supports the circuit board. The support unit is configured to support at least one circuit board. When supporting a plurality of circuit boards, it is preferable that the support unit be supported in a state where the circuit boards are stacked, because the rotating unit can be made smaller. . Further, the support portion may be formed in advance so as to support a plurality of circuit boards, and when using the terminal device of the present invention, a smaller number of circuit boards than the number of circuit boards that can be supported may be accommodated. . Such a support portion is formed so as to have a work surface on which the circuit board is taken in and out (inserted and removed). For example, the support portion may be a cylinder having a rectangular cross section, and a circuit board may be taken in and out from one open surface. At this time, one surface where the circuit board is taken in and out becomes a work surface. As described above, if the circuit board is configured to be able to be taken in and out with respect to the support part, there is a possibility that the circuit board may fall out of the support part. Therefore, in order to more reliably prevent the circuit board from falling from the support part, the circuit board may be fixed to the support part using a fastening member such as a bolt.

  The support part preferably has a protective surface for protecting the circuit board in addition to the work surface. The protective surface is preferably formed, for example, by using a plate-like material as a support member forming member. If the support portion is formed in a frame shape using only the rod-shaped material, the circuit board is likely to come into contact with an operator or a component housed in the housing body, and there is a risk of damage due to this contact. Therefore, the support portion is preferably formed using at least one plate-like material, and is configured to protect the circuit board with this plate-like material, and is formed using a rod-like material and a plate-like material. Alternatively, it may be formed using only a plate-like material. For example, a single plate-like material may be provided so as to be perpendicular to the work surface, and one protective surface may be provided, or the work surface may be perpendicular to the work surface and disposed opposite to the circuit board. You may make it have a pair of plate-shaped material and have two protective surfaces. Such a protective surface is arranged so as to be parallel to the opening surface when the rotary unit is stored. When there is one protective surface, the protective surface is arranged on the opening surface side, and the two protective surfaces are provided. In this case, the first protective surface is disposed on the opening surface side. With this arrangement, when the rotary unit is stored, the circuit board is positioned on the back side of the protective surface, so that the operator can be prevented from coming into contact. In addition, if the protective surface located on the opening surface side is equipped with an antistatic part made of an antistatic material during storage, immediately after the operator opens the outer door during maintenance work, etc. It is possible to prevent contact with the circuit board. The antistatic material may be a material having conductivity that can release static electricity charged to the worker, and examples thereof include stainless steel. The antistatic part may be provided only in at least a part of the protective surface, particularly in a place where the operator can easily contact, or the entire protective surface may be formed of an antistatic material. Moreover, it is preferable to attach a handle to the protective surface located on the opening surface side during storage so that the operator can easily perform the rotating operation of the rotating unit.

  The circuit board may be mounted on the support portion so that the mounting surface is orthogonal to the protective surface, or may be mounted so that the mounting surface is parallel to the protective surface. When mounting a plurality of circuit boards, it is preferable to stack the circuit boards so that the mounting surfaces are parallel to each other. Further, as described above, when the rotating unit is housed, the protective surface is arranged so as to be parallel to the opening surface. Therefore, if the circuit board is mounted so that the mounting surface of the circuit board is parallel to the protective surface, the circuit board mounting surface is arranged to be parallel to the opening surface when the rotary unit is stored, and the circuit with a larger mounting surface. Suitable for storing substrates.

  The rotating unit is disposed in parallel to the opening surface of the housing body, and is supported by a horizontal rotation shaft so as to be rotatable with respect to the housing body. The horizontal rotation axis is a rotation axis whose horizontal direction is the horizontal direction, and the rotation unit can be rotated in the vertical direction (vertical direction) by the horizontal rotation axis. The horizontal rotation shaft may be fixed to the casing body so as to be disposed in the casing body when the rotary unit is rotated, or the casing is exposed to the casing body. It may be fixed to the body body. That is, the former has a configuration in which the horizontal rotating shaft is not exposed from the casing body before and after the rotation of the rotating unit, and a part of the rotating unit is exposed from the casing body by rotating. The latter is a configuration in which, before rotating the rotating unit, the rotating unit pivotally supported by the horizontal rotating shaft is pulled out from the housing body and exposed, and the rotating unit is rotated with the horizontal rotating shaft exposed. Such a horizontal rotation shaft may support the rod-like body in a rotatable manner. Moreover, you may utilize a hinge.

  In the former case, the rotating unit has a work surface that is arranged so as to be orthogonal to the opening surface when the rotating unit is housed so that the rotating surface protrudes from the opening surface after being orthogonal to the opening surface and in a parallel state. It is good to support on a horizontal rotating shaft so as to rotate. That is, the rotation unit is rotated so that the work surface is directed from the horizontal direction to the vertical direction. At this time, the protective surface is preferably arranged on the housing body so as to be rotated from the parallel state to the orthogonal state through the intersecting state, that is, from the vertical direction to the horizontal direction. . In this way, when the rotating unit is stored, the mounting surface is disposed so as to be orthogonal to the opening surface, the protective surface is disposed so as to be parallel to the opening surface, and the mounting portion of the circuit board is parallel to the protective surface. If the rotating unit is rotated so that the mounting surface changes from a state orthogonal to the opening surface to a parallel state after crossing the opening surface, the protective surface passes from the state parallel to the opening surface to the crossing state. With the orthogonal state, the mounting surface is similarly disposed so as to be orthogonal to the opening surface, that is, the mounting surface is in the horizontal direction. Therefore, the terminal device of the present invention can not only accommodate a circuit board having a larger mounting surface as described above, but also the direction in which the circuit board is taken in and out from the work surface by the rotation of the rotating unit in the vertical direction and the horizontal direction. The direction from the back side of the operator toward the near side or the direction from the near side to the far side can be employed. With this configuration, the terminal device of the present invention can be stably operated when the operator removes or inserts the circuit board from the work surface, hardly moving in the horizontal direction or the vertical direction from the position where the outer door is opened. And the safety of the operator can be ensured. In addition, the terminal device of the present invention is less likely to drop the circuit board as compared with the case where it is taken in and out in the vertical direction. In the terminal device of the present invention, the rotating unit is rotated so that the work surface protrudes from the opening surface, so that the circuit board can be easily taken in and out. Therefore, in the terminal device of the present invention, maintenance workability can be improved.

  In the latter case, the rotating unit can be freely inserted into and removed from the casing body so that the rotating unit can be pulled out from the casing body or inserted into the casing body while being supported by the horizontal rotating shaft. It is possible to have a slide mechanism. The rotation unit may be pulled out such that the horizontal rotation shaft and the entire rotation unit are exposed from the housing body, or the horizontal rotation shaft and a part of the rotation unit are exposed from the housing body. Also good. Further, a support mechanism is provided so that the rotating unit drawn out from the housing body can be rotated by the horizontal rotating shaft. The rotating unit is rotated so that the work surface arranged so as to be orthogonal to the opening surface in a state of being pulled out from the housing body together with the horizontal rotation shaft is changed from the orthogonal state to the opening surface in a parallel state. In other words, the horizontal rotation shaft may be pivotally supported so that the work surface rotates in the vertical direction from the horizontal direction. At this time, as in the case of the former described above, when the protective surface is configured to be rotated from the parallel state to the orthogonal state through the intersecting state, the circuit board having a larger mounting surface can be accommodated. Further, in this configuration, when the rotating unit is rotated, the circuit board is exposed from the housing body. Therefore, after rotating the rotating unit, the circuit board can be easily taken in and out, and the maintenance workability is excellent.

  The rotary unit may be configured such that its work surface rotates from above to below like a lower-opening door, or its work surface rotates from below to above like an upper-opening door. You may make it do.

  In the former case, the work surface is arranged so as to face upward in the vertical direction when the rotary unit is stored. Therefore, the work surface starts to be seen from above as the rotating unit rotates. For example, when the terminal device is disposed in a relatively low place, the rotation unit can be easily rotated in this rotation direction, and when the work surface is rotated so as to be parallel to the opening surface, the protective surface disposed on the opening surface side is The circuit board can be reliably supported by being positioned below the circuit board. In order to perform such rotation, the horizontal rotation shaft is provided so as to be positioned on the lower side in the vertical direction of the rotation unit when the rotation unit is stored.

  In the latter case, the work surface is arranged so as to face downward in the vertical direction when the rotary unit is stored. Therefore, the work surface starts to be seen from below as the rotating unit rotates. For example, when the terminal device is arranged at a relatively high place, the rotation unit is easy to rotate in this rotation direction, and when the work surface is rotated so as to be parallel to the opening surface, the protective surface arranged on the opening surface side is By positioning the circuit board above the circuit board, the protective surface can be used for preventing rain. In order to perform such rotation, the horizontal rotation shaft is provided so as to be positioned vertically above the rotation unit when the rotation unit is stored.

  Further, a stopper mechanism may be provided so that the rotation unit can be stopped at a predetermined rotation angle. As the stopper mechanism, for example, a mechanism composed of a hook and a hooking member thereof can be mentioned. At this time, one of the hook and the latch member is provided on the rotary unit, and the other is provided at an appropriate location on the housing body, so that the rotary unit is rotated at a predetermined angle and the stop state is maintained at the rotation angle. Can be made. Rotation angle where the work surface is parallel to the opening surface (rotation angle in the horizontal direction), that is, not only the state in which the rotation unit is rotated 90 ° from the stored state (rotation angle 0 ° state) A plurality of hooks or hooking members may be attached so that they can be stopped at a desired angle of less than 0 °. That is, the rotation angle to be stopped may be provided in multiple stages. Alternatively, a stopper member that can automatically stop the rotation unit at a predetermined rotation angle may be used. As such a stopper member, for example, one having a configuration including an expandable / contractable slider, a guide to which the slider is fitted, and a restricting portion for restricting extension of the slider can be cited. A commercially available stay may be used. Such a stopper member is attached to the rotating unit (supporting portion) so that the slider can expand and contract with the rotation of the rotating unit. By attaching this stopper member, when the rotary unit is rotated so that the work surface is parallel to the crossing state from the state orthogonal to the opening surface, the slider extends along with this rotation, and the extension is restricted by the restricting portion. Thus, the rotating unit can be stopped at a predetermined rotation angle. When a stopper member that can change the regulation of the regulation part in multiple stages is used, it is possible not only to rotate the rotary unit by 90 °, but also to stop at a desired angle of more than 0 ° and less than 90 °. Furthermore, as the stopper member, a structure in which the restriction by the restriction portion is removed when the slider exceeds a predetermined extension amount may be used. In the case of this stopper member, by rotating the rotary unit in one direction so as to extend the slider so as to reach the extension amount from which the restriction is removed, the restriction can be released and the rotation can be easily performed in the opposite direction again. it can.

  Furthermore, you may provide the relaxation mechanism which relieve | moderates the speed at the time of rotating a rotation unit. For example, in the case of a rotating unit in which the work surface is arranged upward in the vertical direction when stored, when the rotating unit is rotated from the stored state to perform maintenance work, the rotating unit has its work surface facing from the top to the bottom. Therefore, the speed at which the rotating unit moves downward due to gravity increases. At this time, if the speed is too high, the rotating unit may collide with a member on the lower side of the housing body, and the circuit board may be damaged. On the other hand, in the case of a rotating unit in which the work surface is arranged downward in the vertical direction during storage, when the rotating unit is rotated so as to be stored after performing maintenance work, the rotating unit is moved upward as described above. Since the circuit board is rotated downward from the upper side, the circuit board may be damaged due to a collision or the like. In order to suppress such damage to the circuit board, it is proposed to provide a relaxation mechanism that slows the rotation of the rotating unit. An example of the relaxation mechanism is to use a damper that suppresses a rapid movement, particularly a rotary damper that suppresses a rapid rotational movement. A commercially available damper may be used.

  Furthermore, a suppression mechanism that suppresses rotation of the rotating unit when the rotating unit is stored may be provided. Suppressing rotation means stopping the rotation of the rotating unit physically, and maintaining the work surface in a state orthogonal to the opening surface during storage, that is, the work surface is stationary while intersecting the opening surface. Including not being in the state. If the rotary unit is rotatable during storage, the rotary unit may swing within the housing body, and the circuit board may be damaged, or the outer door may be difficult to close. Similarly, when the rotating unit is stationary with the work surface intersecting the opening surface, that is, when the stationary unit is stationary with the tilted state, the outer door may be difficult to close. Therefore, as a suppression mechanism, for example, a fixing member is separately prepared, and a fixing method in which the rotation unit is fixed to the housing body by this member, and a fixing member is not used, and the work surface is an opening surface. And a non-fixed type in which the position of the rotary shaft is shifted so that the rotary unit does not stand still in a state where the rotary unit protrudes. Of course you may have both. The former includes fixing the fixing unit to the housing body using a fixing member such as a bolt. The latter includes devising the arrangement position of the rotating shaft as described above. Here, when the horizontal rotation axis is provided on the object, if the center of the rotation axis is positioned on the plane (line) passing through the center of gravity of the object, the object will not rotate unless external force is applied. Quiesce. Therefore, the rotation axis is usually provided so as to be positioned on a plane (line) passing through the center of gravity of the object. On the other hand, the center of gravity of a rectangular parallelepiped object exists on a plane including a bisector of each surface of the object when the mass distribution of the object is uniform. However, when the mass distribution of the rectangular parallelepiped object is not uniform, for example, when it is biased toward one surface side, the center of gravity exists with a deviation from the surface including the bisector. At this time, if the rotation shaft is provided so that the center of the rotation shaft is positioned on the plane including the bisector, the object is stationary in a tilted state. The rotating unit according to the present invention may not have a uniform mass distribution depending on the mounting state of the circuit board, and may be biased toward one surface (for example, a protective surface disposed on the opening surface side). In such a case, if the rotation shaft is provided so that the center of the rotation shaft is positioned on the perpendicular bisector of the protective surface, the work surface is stationary with the work surface crossing the opening surface, that is, the work surface is moved from the opening surface. There is a risk of standing still in the protruding state. Therefore, it is preferable to provide the rotation axis so that the center of the rotation axis is located not on the vertical bisector of the vertical bisector but on a line passing through the center of gravity.

  In the present invention, the circuit board is a rectangular plate member on which circuits for performing various processes related to traffic control are formed, and a commercially available motherboard may be used. The mounting surface on which the circuit is formed is usually the surface with the largest area, and this mounting surface is used for components used in various processes, for example, a CPU for calculating and determining data, and storing data. A memory to be used and a communication component for receiving and transmitting data are mounted. A connector is provided on one end face where the circuit is not formed so that wiring connected to a traffic control device such as a vehicle detector or a traffic light or a central processing unit of a traffic control center is connected. That is, in the present invention, a circuit board to which the wirings can be directly connected is used. That is, the circuit boards are connected in parallel. By using such a circuit board, even when a plurality of circuit boards are accommodated, when performing maintenance work such as repair or component replacement, only a desired circuit board is taken out without removing unnecessary circuit boards. be able to. Therefore, it is preferable to use such a circuit board because of excellent maintenance workability. On the other end surface of the circuit board where the connector is not provided, for example, on the opposite surface of the surface provided with the connector, there is an inspection unit that can confirm whether the mounted components mounted on the circuit board are in a good state. It may be provided. As the inspection unit, for example, a light emitting member such as a light emitting diode (LED) is used, and the light emitting member and the mounting component are electrically connected. Can be grasped, the operator can easily confirm the state of the mounted component by visual observation. When the circuit board is attached to the support part so that the surface having such an inspection part is on the work surface side, the inspection part can be easily confirmed when the work surface starts to be visible by rotating the rotating unit a little. Can do.

  In the terminal device of the present invention in which the rotating unit with the circuit board mounted thereon is housed in the housing body, the rotating unit is rotated so that the state at the time of housing and the state in which the circuit board is rotated to be taken in and out are Thus, the arrangement direction of the circuit board can be changed. For example, when the circuit board is mounted, the mounting surface of the circuit board faces in the vertical direction, and the rotation of the rotary unit can make it horizontal. Therefore, the circuit board can be easily attached and detached. Thus, the terminal device of the present invention can accommodate a larger circuit board in a smaller housing body. Moreover, even if a terminal device of the present invention accommodates a plurality of circuit boards, it is excellent in workability such as repair and replacement. In addition, operations such as repair and replacement can be performed more safely.

Embodiments of the present invention will be described below with reference to the drawings.
<Overall configuration>
FIG. 1 is a perspective view of the traffic control terminal device according to the present invention in an installed state. Hereinafter, the same reference numerals in the drawings denote the same items. This terminal device is a container for storing a circuit board 1 that performs various processes related to a traffic control system, and has an opening 10o on a front surface 10f, and a casing body 10 in which the circuit board 1 is stored, and an opening 10o And an outer door 11 for opening and closing. The most distinctive feature of this terminal device is that the circuit board is not housed in the internal space of the casing body as it is, but the circuit as a rotating unit 12 that can be rotated so that the arrangement position of the circuit board 1 can be changed. The purpose is to accommodate the substrate 1. The rotation unit 12 includes a circuit board 1 and a support portion 13 that detachably supports the circuit board 1.

And four side surfaces 10s orthogonal to the front surface 10f and the back surface 10b. In this example, a rectangular hole is provided in the front surface 10f, a frame is fixed to the hole so as to protrude from the front surface 10f, and a flange is provided on the edge of the frame so as to extend outward. The open space is the opening 10o. The surface formed by the opening 10o is the opening surface. The casing body 10 is installed vertically so that the short side of the opening surface is in the horizontal direction and the long side is in the vertical direction. When the circuit board 1 is normally stored without performing maintenance work such as inspection and repair with respect to the housing body 10 shown in this example, the mounting surface 11 (see FIGS. 2 and 3 described later) of the circuit board 1 is an opening surface. They are arranged in parallel. Therefore, the opening surface is sufficiently larger than the mounting surface of the circuit board 1. In addition, inside the casing body 10, in addition to the rotating unit, wiring (not shown) connected to a connector 1con (see FIG. 3 described later) provided on the circuit board 1, and this wiring and a traffic control device In addition, a wiring (not shown) connected to the central processing unit, a connection terminal unit 100 for connecting these wirings, and the like are stored, and thus a space is provided for storing them. In this example, the rotary unit 12 is housed in the upper side of the internal space of the housing body 1, the connection terminal unit 100 is housed in the lower side, the drive power line for the circuit board 1 is An insertion portion (not shown) into which a wiring connected to a control device or the like is inserted is provided. The casing body 10 and the outer door 11 described later were formed of stainless steel with anticorrosion coating.

<Outside door>
The opening 10 o of the housing body 10 is opened and closed by the outer door 11. The outer door 11 is a so-called side-opening door that is rotatably fixed to the housing body 10 by a hinge (not shown) having a vertical rotation shaft, and opens and closes by rotating in the left-right direction (horizontal direction). . In this example, it is a right-open type that opens by rotating from the left side to the right side and closes by rotating from the right side to the left side. By closing the outer door 11, the circuit board 1 mounted on the rotating unit 12 is prevented from being exposed to wind and rain, and by opening the outer door 11, the rotating unit 12 is rotated at an angle of 0 ° to 90 °. The circuit board 1 can be stored, inspected, repaired, and replaced by rotating the rotating unit 12. In this example, the outer door 11 has a cross-sectional shape (see FIG. 4 described later) and is provided on the front surface 10f so that rainwater can be more effectively prevented from entering the housing body 10. The opening 10o is covered with the outer door 11, and a packing 10p (see FIG. 4 described later) is disposed between the outer door 11 and the housing body 10 (a flange provided on the frame).

<Rotating unit>
<Circuit board>
FIG. 2 is a perspective view schematically showing a rotation unit provided in the terminal device of the present invention, and FIG. 3 is a schematic configuration diagram of a circuit board accommodated in the terminal device of the present invention. The rotation unit 12 includes a circuit board 1 and a support portion 13 that detachably supports the circuit board 1, and is formed in a substantially rectangular parallelepiped shape as shown in FIG. The support part 13 is formed in a cylindrical shape with a rectangular cross section, and the circuit board 1 can be removed from the support part 13 by pulling out or inserting the circuit board 1 from one open surface (work surface 13f), or the support part It can be attached to 13. As shown in FIG. 3, the circuit board 1 is a rectangular thin plate-like member, and a surface having a large area is used as a mounting surface 1l. On the mounting surface 1l, mounting components (not shown) such as a CPU, a memory, and a communication component used for various processes related to traffic control are mounted, and a circuit is formed. In this example, a commercially available motherboard is used as the circuit board 1. A connector 1con is attached to the circuit board 1 side (the short side in this example) so that wiring connected to the traffic control equipment such as vehicle detectors and traffic lights and the central processing unit of the traffic control center is connected. ing. In addition, a plate-like flange 1f is provided on the surface opposite to the surface where the connector 1con is attached, and the circuit board 1 is supported by the flange 1f so as to be in contact with the work surface 13f (see FIG. 3) of the support portion. Attach to. Therefore, when the circuit board 1 is mounted on the support portion, the side on which the connector 1con is attached is arranged on the surface side facing the work surface in the support portion. A pair of knobs 1p are attached to the flange 1f so that the flange 1f can be easily inserted into and pulled out from the cylindrical support portion. Furthermore, the flange 1f is provided with an inspection portion 1c so that it can be visually confirmed whether the mounted components and the circuit are in a good state. In this example, multiple LEDs with different colors were prepared, and these LEDs were electrically connected to the mounted components and circuits so that the status could be confirmed by the lighting color of the LEDs. Such a circuit board 1 may be prepared for each application, for example, for sensing processing that is connected to a vehicle detector to determine the presence or absence of a vehicle, for control processing that is connected to a traffic light and performs signal control, a vehicle Examples include transmission for collecting data from traffic control devices such as detectors and traffic lights and transmitting the data to a traffic control center, and reception for receiving data from the center.

<Supporting part>
In this example, the support portion 13 has a configuration that can be supported in a stacked state so that the mounting surface 11 of the circuit board 1 is parallel as shown in FIG. The support portion 13 has a cylindrical shape with a rectangular cross section, and a pair of protection portions 13a disposed opposite to each other so as to sandwich the circuit board 1 laminated so that the mounting surface 11 is overlapped from above and below. A pair that holds the protective portions 13a and 13b at a constant interval and connects the protective portions 13a and 13b so that a predetermined number of circuit boards 1 can be sandwiched between the protective portions 13a and 13b. And the connecting portion 13c. The protection portions 13a and 13b were formed using a plate-like material having a size that can cover the mounting surface 1l of the circuit board 1. These protective portions 13a and 13b serve as protective surfaces of the rotary unit 12. The connecting portion 13c is also formed using a plate-like material and is disposed so as to face each other. One surface opened in the support portion 13, that is, one rectangular surface surrounded by the protection portions 13a and 13b and the pair of connecting portions 13c is a work surface 13f used for loading and unloading the circuit board 1. The circuit board 1 is arranged in a direction perpendicular to the mounting surface 1l with respect to the work surface 13f, and is attached to or removed from the support portion 13 by taking in and out with the mounting surface 1l facing in the horizontal direction. It can be performed. In this example, the working surface 13f is provided with an abutting portion 13d where the flange 1f of the circuit board 1 abuts, and the circuit board 1 is inserted into the support portion 13 until the flange 1f contacts the abutting portion 13d. Thereafter, the circuit board 1 can be fixed to the contact portion 13d with a fixing bracket such as a bolt.

  FIG. 4 (A) is a front view showing a storage state in which the rotating unit is not rotating in the terminal device of the present invention, and FIG. 4 (B) is a cross-sectional view taken along the line BB in FIG. 4 (A). FIG. 4 shows a state where the outer door is removed (the outer door shown in FIG. 4B is virtual). FIG. 4 shows a state where the circuit board is removed from the rotating unit. When the rotating unit 12 is not rotated (in the state shown in FIG. 4), the rotating unit 12 is positioned on the upper side in the vertical direction and the connection terminal unit 100 is positioned on the lower side in the vertical direction as described above. It is stored in the main body 10. At this time, the protection portions 13a and 13b of the rotary unit 12 are arranged so as to be parallel to the opening surface, and the work surface is orthogonal to the opening surface, that is, parallel to the lower surface 10u of the housing body 10 and facing downward in the vertical direction. Arranged so that. At this time, the circuit board is also arranged so that the mounting surface is parallel to the opening surface. In this stored state, the protective part 13a arranged on the opening surface side is such that when the outer door 11 is opened, the operator immediately contacts the circuit board, and the circuit board is damaged by the charged static electricity. In order to prevent this, the whole was formed of an antistatic material. Specifically, it was formed of stainless steel. Further, the protection unit 13a is provided with a handle 14 so that the rotation unit 12 can be easily rotated. In this example, in order to rotate the rotary unit 12 from below to above as described later, the handle 14 is disposed on the lower side of the protective portion 13a, that is, on the work surface side in the housed state. The support portion 13 shown in this example can store four circuit boards, but may be used by storing one to three circuit boards.

"Axis of rotation"
FIG. 5 (A) is a front view showing a state where the rotating unit is rotated so that the work surface is parallel to the opening surface in the terminal device of the present invention, and (B) is a right side view of (A). FIG. 5 shows a state where the outer door is removed and the circuit board is removed from the rotating unit. As shown in FIGS. 2 and 4, each of the connecting portions 13c is provided with a horizontal rotating shaft 12s of a short rod-like body, and the rotating shaft 12s is rotatably fixed to the housing body 10. The pair of horizontal rotation shafts 12s are arranged such that the axis center lines are on the same straight line. The horizontal rotation shaft 12s rotates from the bottom to the top so that the work surface of the rotation unit 12 changes from the orthogonal state to the crossing state with respect to the opening surface shown in FIG. 4 to the parallel state shown in FIG. It is attached to the rotation unit 12 as follows. More specifically, a horizontal rotating shaft 12s is attached to the upper side of the rotating unit 12 during storage (see FIG. 2). When the rotating unit 12 is rotated, the working surface side of the rotating unit 12 protrudes from the opening 10o as shown in FIG.

  By providing such a horizontal rotation shaft 12s and rotating the rotary unit 12, the circuit board arrangement state can be changed. Specifically, in the storage state shown in FIG. 4, the circuit board is stored in the housing body so that the mounting surface of the circuit board is parallel to the opening surface. For this reason, a large circuit board can be sufficiently accommodated. On the other hand, when the circuit board is removed from or attached to the support portion for repair or replacement, the rotating unit is rotated so that the working surface of the rotating unit is parallel to the opening as shown in FIG. As the unit 12 rotates, the circuit board supported by the support portion 13 is also rotated. Then, as shown in FIG. 5, in a state where the work surface of the rotary unit 12 is rotated so as to be parallel to the opening surface, the mounting surface of the circuit board is orthogonal to the opening surface, that is, the state facing the horizontal direction. Become. At this time, the circuit board can be taken in and out so that the mounting surface faces upward in the horizontal direction so as to go from the back side to the near side of the operator or from the near side to the far side. For this reason, the operator can attach and detach the circuit board without dropping the circuit board and without moving the position in the right and left direction and the up and down direction from the position where the outer door is opened. In particular, since the rotated rotating unit has a work surface protruding from the opening 10o, the circuit board can be easily put in and out without being obstructed by the housing body 10. Further, since the mounting surface of the circuit board faces upward in the horizontal direction, the operator can easily confirm the mounting surface. Therefore, the operator can perform the work of attaching and detaching the circuit board efficiently and more safely. In FIG. 5 (A), since the circuit board is not attached to the support portion 13, a connector con for attaching wiring connected to the connector of the circuit board is visible on the work surface of the rotary unit 12. .

  The horizontal rotation shaft 12s may be attached to the casing body 10 so that the rotating unit 12 can rotate. In particular, in this example, a damper 20 that relaxes the rotation speed is fixed to the casing body 10, and the damper 20 The rotary shaft 12s is pivotally supported on the shaft. When rotating in the vertical direction like the rotating unit 12 shown in this example, the speed when rotating from the upper side to the lower side is increased, and the rotating unit 12 collides with the housing body 10 and the like, and the circuit board. May be damaged. Therefore, in this example, the damper 20 is disposed so that the rotating unit 12 suddenly contacts the casing body 10 to prevent damage. As this damper 20, a general rotary damper was used. Specifically, FTD-47A manufactured by Fuji Latex Corporation was used. The damper 20 is fixed to the damper frame 21 by a fixing bracket such as a bolt, and the damper frame 21 is also fixed to the fixing frame 90 by a fixing bracket such as a bolt. The fixing frame 90 is fixed to the housing body 10 by a bolt 91. Accordingly, the horizontal rotation shaft 12s is pivotally supported on the housing body 10 via the damper 20, the damper frame 21, and the fixed frame 90. The connection terminal unit 100 is also fixed to the fixed frame 90 by a fixing member such as a bolt.

<Stopper mechanism>
Further, in this example, a stopper mechanism 30 is provided so that the rotation unit 12 can be stopped at a predetermined rotation angle. The stopper mechanism 30 is a telescopic slider 31, a guide 32 to which the slider is fitted, and a regulating portion that regulates the extension of the slider 31 to a certain length and removes the regulation when a predetermined extension amount is exceeded. (Not shown), which can regulate the extension of the slider 31 in multiple stages. In this example, a one-touch stay B-1479 manufactured by Takigen Manufacturing Co., Ltd. was used as the stopper mechanism 30. The stopper mechanism 30 is attached to one side (left side) of the connecting portion 13c as shown in FIG. 4 (A). Specifically, one end of the guide 32 is fixed in the vicinity of the horizontal rotation shaft 12s at the connecting portion 13c, and one end of the slider 31 is rotatably supported by the shaft 33 on the work surface side of the connecting portion 13c. By providing such a stopper mechanism 30, the work surface of the rotary unit 12 can be automatically kept parallel to the opening surface when performing work such as repair or part replacement. Can be easily pulled out and inserted. In this example, the stopper mechanism 30 is attached only to one side of the pair of connecting portions 13c, but may be attached to both sides. FIG. 5B shows a state where the stopper mechanism 30 is attached to the right connecting portion 13c so that the stopper mechanism 30 can be seen.

  Since the stopper mechanism 30 used in this example can perform length regulation in multiple stages as described above, the rotation unit 12 is not only in a state where the work surface is parallel to the opening surface as described above, but also the work surface. Can be stopped in a state of crossing the opening surface. That is, not only can the rotating unit 12 be rotated 90 ° from the stored state at the rotating angle of 0 °, but also the rotating unit 12 can be rotated and stopped at a predetermined angle greater than 0 ° and less than 90 °. it can. Further, the restriction of the stopper mechanism 30 is released by rotating the rotary unit 12 so that the slider 31 exceeds a predetermined extension amount. In this example, the stopper mechanism 30 is attached so that the restriction of the slider 31 is released when the rotating unit 12 is rotated more than 90 °. Therefore, when the rotating unit 12 is returned to the retracted state, it is rotated by 90 °, and the working surface is rotated upward so that the rotation angle of the rotating unit 12 exceeds 90 ° from the state where the work surface is parallel to the opening surface. By setting the surface to intersect the opening surface, the restriction of the slider 31 is released, and the rotating unit 12 can be easily rotated from the top to the bottom. In addition, in the present example, the damper 20 is provided as described above, so that when the rotary unit 12 is rotated downward from above, the rotary unit 12 is prevented from rotating rapidly downward. Therefore, after the restriction of the stopper mechanism 30 is released, even if the operator releases his / her hand from the rotary unit 12, the rotary unit 12 can return to the stored state without rapidly rotating downward.

<Rotation suppression mechanism>
The rotary unit 12 shown in this example is in a state of being suspended from the housing body 10 with a horizontal rotary shaft 12s disposed on the upper side thereof. Further, depending on the number of circuit boards attached to the rotation unit 12, the mass of the rotation unit 12 may be biased toward the protection unit 13a or the protection unit 13b. In such a rotational unit that is deviated in weight, depending on the position of the rotary shaft, the rotary unit 12 is stationary with the work surface intersecting the opening surface. Therefore, in this example, the center C of the horizontal rotation shaft 12s is not on the bisector Sc that bisects the connecting portion 13c in the horizontal direction as shown in FIG. A horizontal rotation shaft 12s is provided so as to be positioned on a line S shifted by t on the surface side. By arranging the horizontal rotary shaft 12s so as to be shifted from the bisector Sc in this way, the rotary unit 12 is easy to rest in a state in which the work surface is orthogonal to the opening surface in the stored state, and the outer door 11 is difficult to close. Such a problem is suppressed. In this example, the lower side (working surface side) of the rotating unit 12 is fixed to the housing body 10 (fixed frame 90) using a fixing bracket such as a bolt in order to prevent rotation more reliably in the stored state. I am letting.

<Rotating operation of rotating unit>
The rotation operation of the rotation unit 12 will be described in detail. 6 and 7 are explanatory diagrams for explaining the rotating state of the rotating unit in the terminal device of the present invention, FIG. 6 (A) is a storage state where the rotating unit is not rotating, and FIG. A slightly rotated state, FIG. 7A shows a state in which the rotating unit has rotated 90 °, and FIG. 7B shows a state in which the rotating unit has been rotated more than 90 °.

  When the rotary unit 12 is not rotated (when the rotary unit 12 has a rotation angle of 0 °), the slider 31 of the stopper mechanism 30 is stored in the guide 32 as shown in FIG. It is in a short state. At this time, the work surface of the rotary unit 12 faces downward in the vertical direction and is in a state orthogonal to the opening surface (a state parallel to the lower surface 10u of the housing body 10). When the handle 14 is gripped in this state and rotated so that the rotary unit 12 is lifted upward from below, the work surface intersects the opening surface and protrudes from the opening surface. At this time, as shown in FIG. 6 (B), along with the rotation of the rotary unit 12, the stopper mechanism 30 also rotates around the shaft 33 to bring the stopper mechanism 30 into an appropriate position and the slider 31 starts to slide. Elongate. When the rotary unit 12 rotates so that the slider 31 reaches a predetermined extension amount, extension of the slider 31 is restricted by the restricting portion, so that the rotary unit 12 stops at the rotation angle. That is, in the terminal device shown in this example, even when the rotation angle of the rotation unit 12 is in the range of more than 0 ° and less than 90 ° as shown in FIG. 6 (B), the state stopped at the predetermined rotation angle is maintained. be able to.

  Further, when the outer door 11 is opened, in the housed state shown in FIG. 6 (A), the mounting surface cannot be seen because the circuit board is covered with the protection part 13a. In addition, the work surface of the rotary unit 12 is also invisible because it faces downward, and the flange of the circuit board cannot be seen. However, as shown in FIG. 6 (B), as the rotating unit 12 rotates, the working surface starts to be seen from below, so that the flange of the circuit board also begins to be seen. In particular, in the state shown in FIG. 6 (B), the working surface of the rotary unit 12 protrudes from the housing body 10, so that the flange of the circuit board can be visually confirmed. Therefore, the operator can check the inspection part provided on the flange of the circuit board without removing the circuit board from the support part 13. In addition, since workers other than the worker who is rotating the rotary unit 12 can also check the inspection section from the surroundings, it is possible to perform the inspection work by a plurality of workers. Certainty can be improved.

  Further, the rotation unit 12 is lifted upward so that the work surface is parallel to the opening surface as shown in FIG. 7 (A) (so that the protection portions 13a and 13b are orthogonal to the opening surface). Rotate to be at °. At this time, the circuit board is arranged so that the mounting surface is orthogonal to the opening surface (in parallel with the protection portions 13a and 13b), and this state is maintained by the stopper mechanism 30. Therefore, the circuit board can be taken in and out without the operator supporting the rotating unit 12. Further, in the state shown in FIG. 7A, the upper part of the circuit board is covered with the protective portion 13a, so that rain or the like can be prevented from being applied to the circuit board.

  When removing and inserting the circuit board, the operator grasps the knob 1p, pulls out the desired circuit board from between the protective parts 13a and 13b, and after the work such as repair is completed, inserts it between the protective parts 13a and 13b. Good. In this terminal device, since the circuit boards are not directly connected to each other, only a desired circuit board can be taken out without removing unnecessary circuit boards, and workability such as repair is good. In addition, since the direction of loading and unloading the circuit board is the direction from the back to the near side of the operator, or the direction from the near side to the far side, the operator can move the left and right direction and the up and down direction from the position where the outer door is opened. The circuit board can be taken in and out at that position with little movement. Therefore, it is easy to ensure the safety of the operator. Further, since the circuit board is taken in and out in the above-described direction, it is difficult to drop the circuit board when taking in and out.

  When the work such as repair is completed and the circuit board is inserted between the protective portions 13a and 13b, the rotating unit 12 is rotated from the upper side to the lower side to return to the stored state. At this time, as shown in FIG. 7 (B), the rotary unit 12 is rotated from the state where the rotation angle is 90 ° to the upper direction by lifting the rotation unit 12 so that the rotation angle exceeds 90 °. The slider 31 is set to exceed a predetermined extension amount. By rotating the rotary unit 12 in this way, the control of the restricting portion is released, and the rotary unit 12 can be easily rotated from the upper side to the lower side. In particular, in this example, the damper 20 is provided so that the rotating unit 12 can rotate slowly after the control of the restricting portion is released. Then, when the work surface of the rotation unit 12 is in a state orthogonal to the opening surface (rotation angle 0 °), the lower side of the rotation unit 12 is fixed to the fixed frame 90 with a fixing bracket such as a bolt, and the outer door 11 is closed. Good.

  In this example, the rotary unit is rotated from the bottom upward, but may be rotated from the top downward. At this time, if the connecting terminal connector is disposed above the housing body, the rotating unit is disposed below, and a horizontal rotating shaft is provided below the rotating unit, the rotating operation of the rotating unit is facilitated.

  When constructing a traffic control system, the terminal device of the present invention mediates data transmission between the central processing unit and traffic control devices such as traffic lights and vehicle detectors, and controls traffic control devices. It can be suitably used for storing circuit boards.
