Description

  The present invention relates to a security terminal.

  In recent years, security systems have been widely used in which rooms cannot be entered unless authentication using an ID card or personal authentication such as fingerprints is performed, and security of houses, living rooms, office spaces, and the like has been improved. In such a security system, a configuration is known in which a security terminal for performing security cancellation / setting or authentication work is provided on a wall or a door, and communication is performed with the security system (for example, Patent Document 1).

  When such a security terminal is installed on a wall or the like, a method such as a JIS box that accommodates switch wiring devices has been standardized (see, for example, Patent Document 2). For this reason, the security terminal is also required to be housed in a standard box housed inside such a wall.

Japanese Patent Laid-Open No. 2006-126396 JP 2005-244373 A

  The security terminal may set its operation mode and various operating conditions, and a setting device such as a setting jumper pin or dip switch may be provided. Since these setting devices are related to security, it is desirable to avoid setting them in a place where anyone can access such as the surface of the security terminal. On the other hand, if it is provided on the back surface of the security terminal, that is, in a portion embedded in a wall or the like, it is not dustproof and is not desirable in terms of reliability. However, if a setting device is provided inside the security terminal, the security terminal must be disassembled one by one when changing settings such as operating conditions. Therefore, in security terminals, a desirable arrangement of such setting devices has been demanded.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms.

(1) According to one form of this invention, the security terminal attached to a to-be-attached part is provided. The security terminal includes a main body and a base member for attaching the main body to a predetermined attached portion, and the main body includes an operation unit, a case that houses the operation unit, and the operation unit. And a cover that allows access to the operation unit by moving to the outside of the case, and the base member is capable of inserting the case into the attached portion. The size of the cover in the moving direction when the case and the cover are viewed from the opening having an opening and the cover is in a closed position is larger than the size of the opening in the same direction. When the cover and the cover are not in the closed position, the size of the case and the cover when viewed from the opening is larger than the size of the opening in the same direction.
According to this form, when the cover is in the closed position, the case and the cover can be inserted into the opening, but when the cover is not in the closed position, the case and the cover cannot be inserted into the opening. Forgetting to close the cover prevents dust from entering the operation unit.

(2) In the above embodiment, the case has a guide portion that guides the movement of the cover, and the cover and the guide portion are required to move the cover from the closed position to a position other than the closed position. You may provide the engaging mechanism provided so that force might become larger than the force required for the movement of the said cover in the position except the said closed position.
According to this aspect, the cover can be hardly moved from the closed position by the engagement mechanism when the case is inserted into the opening or after the case is inserted.

(3) In the above aspect, the engagement mechanism is provided on one member of the guide portion and the cover, and is provided on a first protrusion that protrudes toward the other member, and on the other member. A second protrusion protruding toward one of the members, and when the cover is in the closed position, the first protrusion and the second protrusion are engaged with each other so that the cover is outside the case. When the cover is not in the closed position without protruding, the first protrusion may be displaced from the second protrusion, and the cover may protrude outward from the case.
According to this aspect, when the cover is in the closed position, the first protrusion and the second protrusion engage with each other, so that the cover does not protrude beyond the case, and when the cover is not in the closed position, the first protrusion Is displaced from the second protrusion and causes the cover to protrude outward from the case, so that when the case is inserted into the opening, it is possible to notice that the cover has been forgotten to close.

(4) In the above aspect, when the second protrusion has a larger size in the movement direction than the first protrusion, the second protrusion has a recess, and the cover is in the closed position, The engagement between the first protrusion and the second protrusion may be realized by engagement between the first protrusion and the recess.
According to this aspect, when the cover is in the closed position, the first protrusion and the concave portion in the second protrusion are engaged and the engagement is realized, so that the cover is difficult to move from the engaged state.

(5) In the above aspect, the first protrusion may be provided on the guide portion, and the second protrusion may be provided on the cover.
According to this aspect, by changing the size of the second protrusion, the amount of protrusion of the cover from the case when the cover is not in the closed position can be changed, so that it is possible to deal with openings of various sizes.

(6) In the above aspect, the second protrusion may protrude from an end surface of the cover in a direction along the guide portion.
According to this embodiment, the strength of the second protrusion can be increased.

(7) In the above aspect, the cover may have a rib on an end surface of the cover.
According to this form, the strength of the cover can be increased by the rib.

(8) In the above aspect, the case may include a first stopper that locks the cover in the closed position when the cover is closed.
According to this aspect, since the first stopper that locks the cover in the closed position when the cover is closed is provided, it is possible to prevent the cover from being further moved from the closed position and the operation unit from being covered by the cover.

(9) In the above aspect, the case may include a second stopper that locks the cover in a fully opened position where the operation unit can be accessed when the cover is opened.
According to this embodiment, when the cover is opened, the cover is locked by the second stopper, so that the cover can be prevented from being removed from the case.

  The present invention can be realized in various forms, for example, in a form such as a security terminal, a dustproof structure of the security terminal, a dustproof method, and the like.

First embodiment:
FIG. 1 is an explanatory diagram illustrating the security terminal 20 and the attached portion 50 according to the first embodiment. FIG. 2 is a perspective view of the main body 10 of the security terminal 20 as seen from the back side. The security terminal 20 is a part of a security system for authenticating an ID card, and is installed on a wall or a pillar (hereinafter referred to as “wall or the like”) near the door. The security terminal 20 includes a main body 10 and a base member 40. The main body 10 is attached to the attached portion 50 provided on the wall or the like via the base member 40.

  The attached portion 50 is a member attached to a wall or a pillar, and includes a storage portion 51 and a flange portion 52. The storage unit 51 has a hollow box shape that can store a case provided on the back surface of the main body 10 of the security terminal 20. The base member 40 is attached to the flange portion 52. As the attached portion 50, for example, a JIS box which is a standard product may be used.

  The base member 40 is a substantially plate-like member, and has an opening 41 at the substantially center that is a position corresponding to the storage portion 51. The size of the opening 41 will be described later. A standing portion 43 is provided on the outer edge portion 42 around the opening 41. The standing portion 43 is formed with a screw hole 44 for fixing the main body.

  The main body 10 includes a substantially rectangular panel 11, a case 14 provided on the back surface of the panel 11 to form a storage space, and a cover 16 provided on the back surface of the case 14. A reader 12 is provided on the surface of the panel 11. When the ID card is held over, the reader 12 communicates with the ID card and reads data stored in the ID card. The read data is sent to a computer (not shown) and authenticated. The opening / closing of the door is controlled according to the authentication result. Instead of the reader 12, a configuration including a detection unit that detects a fingerprint, a vein, and a palm shape, a touch sensor, and the like may be used. The authentication method is not limited to ID card authentication, and various methods can be adopted.

  A screw hole 13 is provided on the side surface of the panel 11, and the main body 10 is fastened to the screw hole 44 of the base member 40 by a screw 60. The size of the panel 11 is larger than the outer shape of the base member 40. When the main body 10 is attached to the base member 40, the base member 40 is hidden by the panel 11. The screw hole 13 is preferably recessed from the end surface of the panel 11 so that the screw 60 does not protrude from the end surface of the panel 11.

  In the storage space formed by the case 14, electronic devices necessary for the security terminal 20 and the operation unit 142 are stored. On the back surface of the case 14, a plurality of openings 143 are provided at positions corresponding to the operation unit 142. One opening 143 may be provided. The operation unit 142 includes, for example, a jumper pin terminal and a dip switch. The security terminal 20 is set according to the connection of the jumper pin terminal and the state of the dip switch. The cover 16 is provided so as to slide between a position that covers the plurality of openings 143 (“closed position”) and a position that does not cover the plurality of openings 143 (simply referred to as “movement”). ing. When the cover 16 is in a position that does not cover the plurality of openings 143, the opening 143 and the operation unit 142 in the opening 143 can be accessed.

  The case 14 includes a guide portion 144 that guides the movement of the cover 16 and a first stopper 148 around the opening 143. The guide portions 144 are provided in parallel so as to face each other with a distance corresponding to the width of the cover 16 at a position sandwiching the opening 143. A mechanism in which the cover 16 is guided by the guide portion 144 and moves from the closed position, a structure that limits the movement range, and the like will be described later.

  FIG. 3 is an explanatory view showing a state where the cover 16 is in the closed position, and FIG. 4 is an explanatory view showing a state where the cover 16 is in the fully opened position. When the cover 16 is in the closed position, the operation unit 142 and the opening 143 are hidden by the cover 16. Accordingly, dust can be prevented from entering the operation unit 142 and the opening 143. On the other hand, when the cover 16 is not in the closed position, for example, as shown in FIG. 4, when the cover 16 is in the fully open position, the operation unit 142 and the opening 143 are not hidden by the cover 16 and can be accessed. It is.

  When the cover 16 is in the closed position, the end surface 166 of the cover 16 does not protrude beyond the end surface 146 of the case 14 to the outer edge side. On the other hand, when the cover 16 is not in the closed position, the end surface 166 of the cover 16 protrudes to the outer edge side of the end surface 146 of the case 14. However, when the cover 16 is in the closed position, even if the end surface 166 of the cover 16 slightly protrudes from the end surface 146 of the case 14, the relationship described later may be satisfied.

  As can be seen from FIG. 3, when the cover 16 is in the closed position, the first stopper 148 and the end surface 168 of the cover 16 are in contact with each other. That is, when the cover 16 is moved to the closed position, the first stopper 148 locks the cover 16 and restricts the movement range so that the cover 16 does not move too much beyond the closed position. Note that the first stopper 148 may be omitted as long as the cover 16 can be locked in the closed position.

  FIG. 5 is an explanatory diagram showing an enlarged engagement mechanism when the cover 16 is in the closed position (FIG. 4). The engagement mechanism includes a first protrusion 145 provided on the guide portion 144 and a second protrusion 162 provided on the cover 16. The second protrusion 162 is larger in the moving direction of the cover 16 than the first protrusion 145. The second protrusion 162 includes a recess 163 that can be engaged with the first protrusion 145 at a substantially central portion in the moving direction of the cover 16. When the cover 16 is in the closed position, the first protrusion 145 engages with the recess 163 of the second protrusion 162. In the engaged state, in order to move the cover 16 from the closed position to a position that is not the closed position, the first protrusion 145 must exceed the second protrusion 162, and thus a force is required. Therefore, in the closed position, the position of the cover 16 can be maintained so that the cover 16 does not move from the closed position, and the cover 16 can be prevented from opening naturally. Note that this force is greater than the force required to move the cover 16 at positions other than the closed position.

  In the present embodiment, the second protrusion 162 is provided on the end surface of the cover 16 on the guide portion 144 side (also referred to as “the end surface in the width direction of the cover 16”), but on the end surface in the width direction of the cover 16. If it exists, it may be provided anywhere. The first protrusion 145 is provided at a position corresponding to the recess 163 in the closed position of the cover 16. The second protrusion 162 preferably has a shape that facilitates insertion of the first protrusion 145 when the cover 16 is moved from the closed position to the closed position. In the present embodiment, the second protrusion 162 has a slope 169 to facilitate insertion of the first protrusion 145 into the recess 163. The first protrusion and the second protrusion are made of resin. When the first protrusion 145 contacts the slope 169, the first protrusion 164 is deformed outward along the slope 169, and the first protrusion 145 is the recess 163. When the position is reached, the deformation of the first protrusion 145 returns to the original state, and the first protrusion 145 and the second protrusion 162 are engaged. In the present embodiment, the second protrusion 162 has the inclined surface 169 as a shape in which the first protrusion 145 can be easily inserted, but may have a shape other than the inclined surface 169, for example, a curved surface.

  In the present embodiment, of the two side surfaces of the concave portion 163, the side surface 164 on the outer edge side of the first convex portion 145 is a steeper slope than the slope 169. Therefore, even if the cover 16 tries to move to the left from the closed position, the inclined surface 164 restricts the movement of the first convex portion 145, so that the cover 16 can be prevented from moving to the left from the closed position.

  FIG. 6 is an explanatory diagram showing an enlarged engagement mechanism when the cover 16 is not in the closed position. When the cover 16 is not in the closed position, the first protrusion 145 is displaced from the second protrusion 162 so that the first protrusion 145 is positioned on the left side of the second protrusion 162. As a result, the end surface 166 of the cover 16 has moved outward from the closed position for at least the length from the recess 163 to the end of the second protrusion 162. As a result, the end surface 166 of the cover 16 protrudes from the end surface 146 of the case 14 to the outer edge side. Next, the relationship between the size of the opening 41 of the base member 40 and the amount of protrusion of the cover 16 from the case 14 when the case 14 and the cover 160 are not in the closed position will be described.

  FIG. 7 is an explanatory view showing the base member 40. The base member 40 is a substantially plate-like member described above, and includes an opening 41, a standing portion 43, and a screw hole 44. The opening 41 has a size that can accommodate the case 14 of the main body 10. The size of the opening 41 along the moving direction of the cover 16 is L1.

  FIG. 8 is an explanatory view of the main body 10 and the base member 40 viewed from the case 14 side when the cover 16 is not in the closed position. In the present embodiment, the size of the cover 16 in the moving direction when the case 14 and the cover 16 are viewed from the opening 41 when the cover 16 is in the closed position is larger than the size of the opening 41 in the same direction. When the cover 14 is small and the cover 16 is not in the closed position, the size in the same direction when the cover 14 and the cover 16 are viewed from the opening 41 is larger than the size in the same direction of the opening 41. Specifically, the size of the case 14 in the moving direction of the cover 16 is L2, and the amount of protrusion of the end surface 166 of the cover 16 from the end surface 146 of the case 14 when not in the closed position is L3. The relationship of L2 <L1 <L2 + L3 is satisfied. In this case, when the cover 16 is not in the closed position, either the cover 16 or the case 14 is caught by the opening 41, so that the case 14 cannot pass through the opening 41 and the case 14 and the cover 16 are stored in the attached portion 50. Cannot be stored or is extremely difficult to store. As a result, it can be seen that the cover 16 is not in the closed position. That is, forgetting to close the cover 16 can be prevented. On the other hand, when the cover 16 is in the closed position, the case 14 can pass through the opening 41, so that the case 14 and the cover 16 can be stored in the attached portion 50. Here, when the cover 16 is in the closed position, the operation unit 142 and the opening 143 during storage are hidden by the cover 16.

  As described above, according to the present embodiment, when the cover 16 is not in the closed position, the case 14 cannot be stored in the attached portion 50 through the opening 41, so that it is possible to prevent forgetting to close the cover 16. On the other hand, when the cover 16 is in the closed position, the case 14 can be housed in the attached portion 50 through the opening 41, and dust can be prevented from entering the operation portion 142 and the opening 143.

  The present embodiment has a configuration including an engagement mechanism that holds the cover 16 in the closed position, specifically, a first protrusion 145, a second protrusion 162, and a recess 163. As a result, since the cover 16 is held in the closed position, the cover 16 is difficult to move when the case 14 is inserted into the opening 41 or after insertion.

  According to the present embodiment, the first protrusion 145 is provided on the guide portion 144, and the second protrusion 162 is provided on the cover 16. According to this configuration, the amount of protrusion of the cover 16 from the case 14 when not in the closed position can be changed by changing the size of the second protrusion 162. Therefore, it is possible to deal with the openings 41 of various sizes only by changing the size of the second protrusion 162.

  FIG. 9 is an explanatory view showing another shape of the cover 16. The cover 16 is different in that the second protrusion 162 does not protrude from the end surface 168. As described above, the second protrusion 162 may not protrude from the end face 168. This has the same effect as the first embodiment.

Second embodiment:
FIG. 10 is an explanatory diagram illustrating the main body 10 of the security terminal according to the second embodiment. FIG. 10 shows a state where the cover 17 is removed. The difference from the main body 10 of the security terminal of the first embodiment is that the case 14 includes a second stopper 149 that prevents the cover 17 from being opened more than a certain amount and the cover 17 from falling off the case 14.

  FIG. 11 is an explanatory view showing a cover 17 used in the second embodiment. In the second embodiment, the cover 17 is different from the first embodiment in that the four end faces 174 to 177 have ribs that stand substantially vertically from the plane forming the cover 17 toward the case 14. In the second embodiment, since the four end faces 174 to 177 are provided with ribs, the strength of the cover 17 can be increased.

  The cover 17 includes a second recess 178 on the rib of the end surface 174. When the cover 17 is in the closed position, the second stopper 149 just fits in the second recess 178 and prevents dust from entering the operation unit 142.

  Further, when the cover 17 is opened, the second stopper 149 comes into contact with the end surface 175 opposite to the end surface 174 provided with the second recess, so that it is possible to prevent the cover 17 from being opened too much and falling off the case 14. That is, in the present embodiment, the end surfaces 174 to 177 of the cover 17 are provided with ribs facing the direction of the case 14 so that a space through which the second stopper 149 can pass is formed between the cover 17 and the case 14. realizable. Note that the second stopper 149 may not be provided. In this case, the second recess 178 is unnecessary. Intrusion of dust can be suppressed. Further, the second stopper 149 may be provided in the guide part 144. The second protrusion 162 hits the second stopper 149, and the cover 17 can be prevented from falling off.

  FIG. 12 is an explanatory view showing a cross section of the cover 17 shown in FIG. Flange portions 179 are provided on end surfaces 176 and 177 of the cover 17. In the present embodiment, the flange portion 179 and the second protrusion 172 (FIG. 11) are accommodated in the guide portion 144 of the case 14. As a result, even if the guide portion 144 has a thin structure, the height of the rib of the cover 17 can be increased to form a space through which the second stopper 149 can pass. The flange portion 179 may be omitted.

  In each of the above embodiments, the guide portion 144 has the first protrusion 145 and the cover 16 has the second protrusion 162 and the recess 163, but the guide portion 144 has the second protrusion and the recess, and the cover 16 may have a first protrusion. That is, a first protrusion provided on one member of the guide portion 144 and the cover 16 and protruding from the other member, and a second protrusion provided on the other member and protruding from the one member, What is necessary is just to provide the 2nd protrusion larger in the magnitude | size of a moving direction than a protrusion, and the recessed part provided in the 2nd protrusion. Moreover, in each said embodiment, although 2 sets of engagement mechanisms are provided, the structure provided only with 1 set may be sufficient.

  In each of the above embodiments, the engagement mechanism is provided by the engagement of the first protrusion 145 and the recess 163, but the engagement mechanism may be an electromagnetic engagement mechanism. For example, the structure which equips each with the magnet in the position corresponding to a 1st protrusion and a 2nd protrusion, or the metal which attaches to a magnet and a magnet, respectively may be sufficient. Note that the engagement mechanism is not always necessary.

Third embodiment:
FIG. 13 is an explanatory view showing, in an enlarged manner, the engagement mechanism when the cover 16 is in the closed position in the third embodiment. The third embodiment is different from the first embodiment in the shape of the second protrusion 162. The second protrusion 162 of the first embodiment includes a recess 163, but the second protrusion 162 of the third embodiment has a second protrusion 162 at a portion closer to the opening side of the cover 16 than the position corresponding to the recess 163. The part of has been deleted. Also in this embodiment, the cover 16 can be locked in the closed position so that the cover 16 is not opened by the engagement of the first protrusion 145 and the second protrusion 162. In the closed position, the second protrusion 162 has a slope 165 on the first protrusion 145 side. This is because when the force for opening the cover 16 is not applied, the cover is locked so that the cover 16 does not open, and when the force for opening the cover 16 is applied, the second protrusion 162 can easily get over the first protrusion 145. It is.

  In each of the embodiments described above, the cover 16 moves in parallel, but the cover 16 may be configured to rotate about one corner thereof. Even when the cover 16 is rotated, when the cover 16 is not in the closed position, the cover 16 protrudes from the case 14, so the case 14 cannot pass through the opening 41. As a result, forgetting to close the cover 16 can be suppressed.

  The present invention is not limited to the above-described embodiment, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features of the embodiments corresponding to the technical features in each embodiment described in the summary section of the invention are intended to solve part or all of the above-described problems, or part of the above-described effects. Or, in order to achieve the whole, it is possible to replace or combine as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.
