Description

  The present invention relates to a portable device of an electronic key system in which an emergency key is attached to a portable device body.

  2. Description of the Related Art Conventionally, there has been known an electronic key system that performs operations such as locking and unlocking of a vehicle door, start of an engine, and the like by performing wireless communication between a communication target device such as a vehicle and a portable device. In the electronic key system, wireless communication between the portable device and the communication target device can not be performed if the battery of the portable device runs out, the failure of the portable device, or the like occurs. In the conventional portable device, in order to cope with such an emergency, a mechanical key called an emergency key is stored in the portable device body. When wireless communication between the portable device and the communication target device can not be performed, the mechanical operation of the emergency key removed from the portable device body performs operations such as locking and unlocking of the vehicle door and starting of the engine. Can.

  Conventionally, there has been proposed a portable key of an electronic key system in which the emergency key can be attached to and detached from the main body of the portable device by providing the emergency key with a recess and providing a locking member to be inserted into and removed from the recess. When the emergency key is attached to the portable device body, the locking member is inserted into the recess by the force of the spring. The emergency key can be removed from the portable device body by pulling the locking member out of the recess against the force of the spring (see, for example, Patent Document 1).

  Also, conventionally, an electronic key system in which the emergency key is prevented from being detached from the main body of the portable device by providing the release hook slidably on the main body of the portable device and hooking the release hook on a protrusion projecting from the side of the head of the emergency key Portable devices have also been proposed. When the emergency key is attached to the main body of the portable device, the force of the spring holds the release hook hooked on the projection. The emergency key can be removed from the main body of the portable device by sliding the release hook against the force of the spring (see, for example, Patent Document 2).

  However, in the portable device of the conventional electronic key system shown in Patent Document 1, only by performing the operation of pulling out the locking member from the recess, the locking member is released by the force of the spring when the hand is released from the locking member. The emergency key can not be removed from the portable device body. For this reason, it is necessary to remove the emergency key from the portable device body with one other hand while applying force to one side with the lock member in a direction against the force of the spring. Therefore, it takes time and effort to remove the emergency key from the portable device body.

  In addition, even in the portable key of the conventional electronic key system shown in Patent Document 2, the release hook is released by the force of the spring when the hand is released from the release hook simply by removing the release hook from the projection. And the emergency key can not be removed from the portable device body. For this reason, it is necessary to remove the emergency key from the portable device main body with one other hand while applying force with one hand to the release hook in a direction against the force of the spring. Therefore, it takes time and effort to remove the emergency key from the portable device body.

  The present invention has been made to solve the above-described problems, and it is an object of the present invention to provide a portable device of an electronic key system capable of reducing the time and effort when removing an emergency key from the portable device body. I assume.

  The portable key of the electronic key system according to the present invention comprises the portable key body, the detachable member detachably attached to the assembled position of the portable key body, and the emergency key housed in the space surrounded by the portable key body and the detachable member. A release lever provided displaceably on the first part, which is one of the portable device body and the detachable member, interlocked with the release lever, and displaced between the lock position and the release position with respect to the first part Movable portion, an urging body for urging the movable portion to the lock position, a first hook provided on the movable portion, and a second part which is either the portable device body or the detachable member A second hook, the first hook being hooked on the second hook when the movable part is in the locked position, and the displacement of the movable part from the locked position to the release position causes the first hook to be second Hook or not It has a holding mechanism part which comes off, a first guide part provided in the movable part, and a second guide part provided in the second part, and the displacement of the movable part from the lock position to the release position A release mechanism portion is provided for displacing the detachable member from the assembly position in a direction different from the direction in which the movable portion is displaced while guiding the second guide portion to the first guide portion.

  According to the portable device of the electronic key system according to the present invention, the displacement of the movable part from the lock position to the release position causes the release mechanism part to displace the detachable member from the assembled position in a direction different from the displacement direction of the movable part. For this reason, only by displacing the movable portion from the lock position to the release position, the detachable member can be automatically shifted from the assembly position. This makes it possible to prevent the detachable member from being held again in the assembly position. Therefore, it is possible to reduce the time and effort when removing the emergency key from the portable device main body.

A second protrusion 22 is provided as a second stopper on one side cover 10 facing the side surface of the movable portion 14. The first protrusion 21 and the second protrusion 22 are opposed to each other in the direction in which the movable portion 14 is displaced, that is, in the longitudinal direction X of the portable device body 2. The spring 15 is disposed between the first protrusion 21 and the second protrusion 22 in a compressed state. Thus, the spring 15 generates an elastic restoring force that biases the movable portion 14 to the lock position.

  The holding mechanism 16 holds the first cover 3 in the first assembly position when the movable portion 14 is in the lock position. Further, the holding mechanism unit 16 releases the holding of the first cover 3 by the displacement of the movable portion 14 from the lock position to the release position. Further, the holding mechanism portion 16 has a first hook 161 provided to the movable portion 14 and a second hook 162 provided to the first cover 3.

  The first hook 161 is displaced integrally with the movable portion 14 along the longitudinal direction X of the portable device body 2. When the first cover 3 is disposed in the first assembly position, the first hook 161 is hooked on the second hook 162 when the movable portion 14 reaches the lock position.

  The first cover 3 is removed from the first assembled position of the portable device body 2 by being displaced relative to the portable device body 2 along the short direction Y different from the longitudinal direction X. That is, the direction in which the first cover 3 is removed from the first assembly position is different from the direction in which the movable portion 14 is displaced relative to the portable device body 2. When the first hook 161 is hooked on the second hook 162, the displacement of the first cover 3 in the direction away from the first assembly position is prevented. That is, the state in which the first cover 3 is attached to the first assembly position is held by the first hook 161 hooking on the second hook 162.

  The release mechanism unit 17 displaces the first cover 3 relative to the portable device body 2 in a direction in which the first cover 3 is removed from the first assembly position by the displacement of the movable portion 14 from the lock position to the release position. . Further, the release mechanism portion 17 has a first guide portion 171 provided in the movable portion 14 and a second guide portion 172 provided in the first cover 3.

  The first guide portion 171 is displaced integrally with the movable portion 14 along the longitudinal direction X of the portable device body 2. The first guide portion 171 is formed with a first tapered surface 171 a which is inclined with respect to the direction in which the movable portion 14 is displaced, that is, the longitudinal direction X of the portable device body 2. The first tapered surface 171 a is also inclined with respect to the direction in which the first cover 3 is out of the first assembly position, that is, the lateral direction Y of the portable device body 2.

  A second tapered surface 172 a is formed on the second guide portion 172. The second tapered surface 172a is inclined with respect to the longitudinal direction X and the short direction Y of the portable device body 2 in accordance with the inclination of the first tapered surface 171a. When the first cover 3 is disposed at the first assembly position and the movable portion 14 reaches the lock position, as shown in FIG. 5, the first tapered surface 171a and the second tapered surface 172a Are separated from each other in the longitudinal direction X of the portable device body 2. In this example, the second guide portion 172 is integral with the second hook 162.

  The main body portion 7 is provided with a plurality of first blocks 31. Each first block 31 protrudes from the main body 7 toward the first cover 3. The first cover 3 is provided with a plurality of second blocks 32. Each second block 32 protrudes from the first cover 3 toward the main body 7.

  Each first block 31 is provided with a recess 33. The depth direction of each recess 33 coincides with the direction in which the first cover 3 moves away from or approaches the first assembly position, that is, the short direction Y of the portable device body 2. Further, the opening of each recess 33 is provided to the side opposite to the movable portion 14 side.

  Each second block 32 is provided on the first cover 3 in alignment with the position of each first block 31. Further, as shown in FIGS. 3 and 5, the second block 32 has an insertion portion 34 which is a convex portion to be inserted into the concave portion 33 of each first block 31.

  The resisting force generating portion 18 applies resisting force to the first cover 3 when being displaced in the direction away from the first assembly position and in the direction approaching the first assembly position. As a result, when the first cover 3 is displaced along the lateral direction Y of the portable device body 2, the resistance generated by the resistance generation unit 18 is applied to the first cover 3.

  The resistance force generation unit 18 includes any one of the first blocks 31 as a first resistance member 181. Further, the resistance force generation unit 18 includes a second block 32 corresponding to the first resistance member 181 as a second resistance member 182.

  Contact portions 34 a which are protrusions are respectively provided on both side surfaces of the insertion portion 34 of the second resistance member 182. The insertion portion 34 of the second resistance member 182 is pressed into the recess 33 while the contact portion 34 a is in contact with the inner surface of the recess 33 of the first resistance member 181.

  In the state in which the first cover 3 is disposed at the first assembly position, the insertion portion 34 of each second block 32 is inserted into the recess 33 of each first block 31. In a state where the insertion portion 34 of each second block 32 is inserted into the recess 33, the first cover 3 is shorted by the portable device main body 2 by the insertion portion 34 being guided in the depth direction of the recess 33. The portable device body 2 is guided in the hand direction Y. In the state where the insertion portion 34 of each second block 32 is inserted into the recess 33, the displacement of the first cover 3 in the longitudinal direction X of the portable device body 2 is blocked.

  In a state in which the insertion portion 34 of the second resistance member 182 is press-fit into the recess 33 of the first resistance member 181, the contact portion 34a is in contact with the inner surface of the recess 33 along the depth direction of the recess 33. That is, in a state in which the first cover 3 is disposed in the first assembly position, the second resistance member 182 contacts a plane along the lateral direction Y of the portable device body 2 in the first resistance member 181 doing. When the contact portion 34 a is in contact with the inner surface of the recess 33, a frictional force is generated between the inner surface of the recess 33 and the contact portion 34 a. Thereby, when the first cover 3 is displaced in the direction out of the first assembly position, and when the first cover 3 is displaced in the direction approaching the first assembly position, the first resistance member 181 The frictional force generated by the contact between the second resistance member 182 and the second resistance member 182 is applied to the first cover 3 as a resistance. The magnitude of the frictional force between the first resistance member 181 and the second resistance member 182 is such that the insertion portion 34 does not come out of the recess 33 due to the weight of the first cover 3.

  At least one of the first blocks 31 is a guide block. In this example, three first blocks 31 arranged at a position close to the movable portion 14 are used as guide blocks. The first block 31 as a guide block is provided with a guide groove 23 along the direction in which the movable portion 14 is displaced, that is, the longitudinal direction X of the portable device body 2.

  The movable portion 14 has an insertion portion 14 a inserted into the guide groove 23. The movable portion 14 is displaced relative to the portable device body 2 while guiding the insertion portion 14 a to the guide groove 23.

  On one side cover 10 facing the side surface of the movable portion 14, a plurality of guide protrusions 24 which are anti-slip portions are provided. The plurality of guide protrusions 24 are spaced apart from one another in the direction in which the movable portion 14 is displaced. The movable portion 14 as viewed in the direction in which the movable portion 14 is displaced is disposed between the first block 31 as a guide block and the guide protrusion 24. Each guide protrusion 24 receives the side surface of the movable portion 14. Thereby, each of the guide protrusions 24 prevents the displacement of the movable portion 14 in the direction in which the insertion portion 14 a is disengaged from the guide groove 23.

  FIG. 6 is a cross-sectional view showing a state in which the holding of the first cover 3 by the holding mechanism portion 16 of FIG. 5 is released. When the movable portion 14 is displaced from the lock position toward the release position in the direction of the arrow P1 in FIG. 6 in the state where the first cover 3 is disposed in the first assembly position, the first hook 161 is displaced. The second hook 162 is disengaged. As a result, the state in which the first cover 3 is held by the holding mechanism 16 is released. Further, in a state where the first cover 3 is disposed in the first assembly position, when the movable portion 14 is displaced from the lock position toward the release position in the direction of arrow P1 in FIG. The surface 171a contacts the second tapered surface 172a.

  FIG. 7 is a cross-sectional view showing the movable portion 14 of FIG. 6 in the release position. 8 is an enlarged cross-sectional view showing the holding mechanism 16, the release mechanism 17 and the resistance generating unit 18 of FIG. When the movable portion 14 is displaced in the direction of the arrow P1 of FIG. 7 toward the release position in a state where the first tapered surface 171a is in contact with the second tapered surface 172a, the resistance force of the resistance generating portion 18 is counteracted. Thus, while the second guide portion 172 is guided by the first guide portion 171, the first cover 3 is displaced in the direction out of the first assembly position, that is, in the direction of the arrow P2 in FIGS. . The release mechanism section 17 guides the second guide section 172 to the first guide section 171 by the displacement of the movable section 14 from the lock position to the release position, and moves the first guide section 171 away from the first assembly position. The cover 3 is displaced. That is, the release mechanism section 17 displaces the key ring 9 from the first assembly position in the short direction Y different from the longitudinal direction X in which the movable section 14 is displaced by the displacement of the movable section 14 from the lock position to the release position. . When the second guide portion 172 is guided by the first guide portion 171, the second tapered surface 172a is guided along the first tapered surface 171a. In the state where the movable portion 14 has reached the release position, the contact portion 34 a of the second resistance member 182 is separated from the inner surface of the recess 33 of the first resistance member 181.

  FIG. 9 is a cross-sectional view showing a state in which the movable portion 14 of FIG. 8 is displaced from the release position toward the lock position. A first contact surface 161 a is formed on the outer surface of the first hook 161. A second contact surface 162 a is formed on the outer surface of the second hook 162. When the first cover 3 is out of the first assembled position, the first contact surface 161a and the second contact surface 162a can be in contact with each other.

  Each of the first contact surface 161 a and the second contact surface 162 a is a tapered surface which is inclined with respect to the direction in which the movable portion 14 is displaced, that is, the longitudinal direction X of the portable device body 2. The inclination directions of the first contact surface 161a and the second contact surface 162a are the same. Further, each of the first contact surface 161a and the second contact surface 162a is in the direction in which the first cover 3 moves away from or approaches the first assembly position, that is, the short direction Y of the portable device main body 2 It is also inclined against. The inclination direction of the first contact surface 161a and the inclination direction of the first tapered surface 171a are opposite to each other. The inclination direction of the second contact surface 162a and the inclination direction of the second tapered surface 172a are opposite to each other.

  When the first contact surface 161a and the second contact surface 162a are in contact with each other, the displacement of the movable portion 14 from the release position to the lock position, ie, the movable portion 14 in the direction of arrow P3 in FIG. The displacement causes the second hook 162 to be guided along the first contact surface 161a and the second contact surface 162a with respect to the first hook 161, but in a direction out of the first assembled position, ie, in FIG. The first cover 3 is displaced in the direction of arrow P2.

  FIG. 10 shows a state in which the first cover 3 receives a force toward the first assembly position when the first contact surface 161a and the second contact surface 162a of FIG. 9 are in contact with each other. It is a sectional view showing. When the first cover 3 is displaced in the direction of the arrow P4 in FIG. 10 toward the first assembly position with the first contact surface 161a and the second contact surface 162a in contact with each other, Direction of the movable portion 14 against the force of the spring 15 and approaching the release position while the first hook 161 is guided along the first contact surface 161a and the second contact surface 162a with respect to the second hook 162, That is, it is displaced in the direction of arrow P1 of FIG. That is, when the first cover 3 receives a force toward the first assembly position with the first contact surface 161a and the second contact surface 162a in contact with each other, the second hook 162 is a spring. The first cover 3 is displaced to the first assembly position while pushing the first hook 161 against the force of 15. The first hook 161 is engaged with the second hook 162 by the force of the spring 15 when the first cover 3 reaches the first assembly position. In this example, the portable device body 2 is a first component, and the first cover 3 is a second component.

  Next, an operation procedure for removing the emergency key 5 from the portable device 1 will be described. In the state where the first cover 3 is disposed at the first assembly position of the portable device body 2, the insertion portion 34 of the second resistance member 182 is press-fit into the recess 33 of the first resistance member 181. Thereby, a resistance is given to the displacement of the first cover 3 in the direction out of the first assembly position. Further, in a state where the first cover 3 is held at the first assembly position of the portable device body 2 by the holding mechanism portion 16, the movable portion 14 is in the locked position by the force of the spring 15 as shown in FIG. And the first hook 161 is hooked on the second hook 162. The displacement of the first cover 3 in the direction away from the first assembly position is blocked by the hooks 161 being hooked on the second hooks 162.

  When removing the emergency key 5 from the portable device 1, first, the operation unit 131 is operated in the direction of arrow A in FIG. 1. As a result, the movable portion 14 is displaced from the lock position toward the release position against the force of the spring 15.

  When the movable portion 14 is displaced from the lock position toward the release position, the first hook 161 is disengaged from the second hook 162, as shown in FIG. As a result, the holding of the first cover 3 by the holding mechanism 16 is released. After this, the first tapered surface 171 a of the first guide portion 171 contacts the second tapered surface 172 a of the second guide portion 172.

  Thereafter, when the operating portion 131 is further operated in the direction of arrow A in FIG. 6, the movable portion 14 is further displaced toward the release position against the force of the spring 15. Thereby, while the second guide portion 172 is guided along the first tapered surface 171a of the first guide portion 171, the first guide portion 172 is deviated from the first assembly position, that is, in the direction of the arrow P2 in FIG. Cover 3 is displaced. At this time, the first cover 3 receives the frictional force between the contact portion 34 a of the second resistance member 182 and the inner surface of the recess 33 of the first resistance member 181 as a resistance.

  Thereafter, the operating unit 131 is further operated in the direction of the arrow A in FIG. 7 so that the movable unit 14 reaches the release position. As a result, as shown in FIG. 8, the contact portion 34 a of the second resistance member 182 is disengaged from the recess 33 of the first resistance member 181. When it is attempted to displace the first cover 3 in the direction approaching the first assembly position, the contact portion 34a of the second resistance member 182 again contacts the inner surface of the recess 33, and the resistance is reduced to the first It is given to the cover 3 again. This makes it difficult for the first cover 3 to return to the first assembly position.

  After that, when the operator releases the operation unit 131, the movable unit 14 is automatically displaced from the release position toward the lock position while the operation unit 131 is displaced in the direction of arrow B in FIG. Be done. At this time, since the position of the first cover 3 is shifted from the first assembly position in the lateral direction Y, as shown in FIG. 9, the first contact surface 161a of the first hook 161 is the second. Contact the second contact surface 162a of the hook 162 of the

  After that, when the movable portion 14 is further displaced toward the lock position by the force of the spring 15, the second hook 162 is illustrated while the second contact surface 162a is guided along the first contact surface 161a. It is pushed by the first hook 161 in the direction of the arrow P2 of 9. Thereby, the first cover 3 is further displaced in the direction out of the first assembly position. After this, the movable portion 14 reaches the lock position.

  Thereafter, as shown by the arrow P in FIG. 2, the first cover 3 is removed from the portable device body 2 by moving the first cover 3 in the thickness direction Z of the portable device body 2. When the first cover 3 is removed from the portable device body 2, the emergency key 5 is exposed to the outside, and the emergency key 5 can be removed from the portable device body 2.

  When the emergency key 5 is stored in the portable device 1 after using the emergency key 5, the emergency key 5 is first attached to the storage position of the main body 7. Thereafter, the first cover 3 is disposed at a position shifted in the lateral direction Y from the first assembly position, and the first cover 3 is displaced in the direction of arrow P4 in FIG. 10 toward the first assembly position. Let

  At this time, the insertion portion 34 of the second resistance member 182 is press-fit into the recess 33 of the first resistance member 181. Thereby, the first cover 3 is displaced toward the first assembly position while receiving the frictional force between the contact portion 34 a of the insertion portion 34 and the inner surface of the recess 33 as a resistive force. At this time, the insertion portion 34 of each other second block 32 is also inserted into the recess 33 of each other first block 31. Furthermore, at this time, the second hook 162 pushes the first hook 161 against the force of the spring 15 while the second contact surface 162a contacts the first contact surface 161a. Thereby, the first hook 161 once approaches the release position integrally with the movable portion 14 against the force of the spring 15. After that, when the first cover 3 reaches the first assembly position, the contact between the first contact surface 161a and the second contact surface 162a is released, and the force of the spring 15 causes the first hook 161 to move to the second position. Hook 162 automatically. Thereby, the first cover 3 is held in the first assembly position. The emergency key 5 is stored in the storage space 12 surrounded by the portable device body 2 and the first cover 3 by holding the first cover 3 at the first assembly position of the portable device body 2 .

  In such a portable device 1, the release mechanism 17 separates the first cover 3 from the first assembly position in a direction different from the direction in which the movable portion 14 is displaced by the displacement of the movable portion 14 from the lock position to the release position. Displace from Therefore, only by displacing the movable portion 14 from the lock position to the release position, the first cover 3 can be automatically shifted from the first assembly position. Thereby, even if the movable portion 14 returns to the original lock position by the force of the spring 15, the first cover 3 can be kept out of the first assembly position, and the first cover 3 can It is possible to prevent the situation where it is held again in the assembly position of 1. As a result, the first cover 3 can be easily removed from the portable device body 2 simply by displacing the movable portion 14 from the lock position to the release position, and the time and effort when removing the emergency key 5 from the portable device body 2 is reduced. Can be implemented.

  Further, in recent years, the portable device 1 is required to improve the designability by decoration so that the user can obtain the joy of owning the portable device 1. For example, resin parts having been subjected to plating, vapor deposition or the like, or metal die-casting parts made of zinc, aluminum or the like may be used for the main body 2 of the portable device, or resin parts having genuine leather attached to the surface may be used. By using for the covers 3 and 4 or the like, the high-class feeling and the solid feeling of the portable device 1 are produced, and the designability of the portable device 1 is improved.

  In the portable device 1 according to the first embodiment, the release lever 13 can be disposed at a position other than the first cover 3 and the second cover 4. For this reason, it is not necessary to provide a lever opening through which the release lever 13 passes through each of the first cover 3 and the second cover 4. Thereby, the fall of the designability of each of the 1st cover 3 and the 2nd cover 4 can be prevented, and the improvement of the designability of the whole portable machine 1 can be aimed at.

  In addition, a resistance force is applied to the first cover 3 when being displaced in the direction approaching the first assembly position by the resistance force generation unit 18. For this reason, it is possible to avoid the situation where the first cover 3 returns to the first assembly position again after displacing the first cover 3 in the direction of coming out of the first assembly position. As a result, it is possible to reduce the time and effort when removing the emergency key 5 from the portable device body 2 more reliably.

  Further, the resistance force generation unit 18 includes a first resistance member 181 provided in the portable device main body 2 and a second resistance member 182 provided in the first cover 3. Further, when the first cover 3 is displaced in the direction approaching the first assembly position, the first resistance member 181 and the second resistance member 182 contact each other with the first cover 3. The resulting frictional force is given as a resistance. For this reason, the configuration of the resistance generating unit 18 can be simplified, and the cost can be reduced.

  Further, the release mechanism portion 17 has a first guide portion 171 provided in the movable portion 14 and a second guide portion 172 provided in the first cover 3. Further, the second guide portion 172 is guided by the first guide portion 171 in the direction in which the first cover 3 is removed by the displacement of the movable portion 14 from the lock position to the release position. Therefore, the release mechanism portion 17 can be configured simply by providing the first guide portion 171 in the movable portion 14 and providing the second guide portion 172 in the first cover 3. As a result, the configuration of the release mechanism 17 can be simplified, and the cost can be reduced.

  When the first cover 3 is out of the first assembled position of the portable device body 2, the first contact surface 161 a formed on the outer surface of the first hook 161 and the outer surface of the second hook 162 And the second contact surface 162a formed on the lower side can be in contact with each other. Furthermore, each of the first contact surface 161a and the second contact surface 162a is a tapered surface that is inclined with respect to the direction in which the movable portion 14 is displaced. Therefore, when the movable portion 14 is displaced from the release position to the lock position in a state where the first cover 3 is deviated from the first assembly position, the second contact surface 162a is along the first contact surface 161a. While being guided, the first cover 3 can be further displaced in the direction away from the first assembly position. Therefore, the first cover 3 can be more easily removed from the portable device body 2 with certainty, and the time and effort required to remove the emergency key 5 from the portable device body 2 can be further reliably reduced.

  Further, in the first block 31 as a guide block provided in the portable device main body 2, a guide groove 23 along the direction in which the movable portion 14 is displaced is provided. Furthermore, the movable portion 14 has an insertion portion 14 a inserted into the guide groove 23. Further, the guide projection 24 provided on the portable device body 2 prevents the displacement of the movable portion 14 in the direction in which the insertion portion 14 a is disengaged from the guide groove 23. Therefore, it is possible to prevent lateral displacement of the movable portion 14 when being displaced between the lock position and the release position. As a result, the movable portion 14 can be displaced more reliably between the lock position and the release position, and the time and effort required for removing the emergency key 5 from the portable device body 2 can be further reliably reduced.

  Further, the spring 15 is disposed between the first protrusion 21 provided on the movable portion 14 and the second protrusion 22 provided on the portable device main body 2. Therefore, the movable portion 14 can be easily biased toward the lock position with a simple configuration.

  In the above example, although the resistance force that the resistance generation unit 18 applies to the first cover 3 is the frictional force between the first resistance member 181 and the second resistance member 182, It is not limited to. For example, the first protrusion for resistance provided on the portable device main body 2 and the second protrusion for resistance provided on the first cover 3 are made to face each other in the lateral direction Y of the portable device main body 2 A resistance spring, which is an elastic body, may be disposed between the first and second resistance projections. Also in this case, when the first cover 3 is displaced in the direction approaching the first assembly position, the elastic repulsive force of the resistance spring can be applied to the first cover 3 as a resistance.

  Further, in the above example, the common first block 31 is used as the guide block and the first resistance member 181. However, the guide block provided with the guide groove 23 may be provided separately from the first resistance member 181.

When the key ring 9 is attached to the assembled position of the portable device body 2, the emergency key 5 is accommodated in the accommodation space 12 along the longitudinal direction X of the portable device body 2. The emergency key 5 comes out of the storage space 12 as the key ring 9 is displaced in the direction away from the portable device body 2 along the longitudinal direction X of the portable device body 2.

  14 is a cross-sectional view along the line XIV-XIV of FIG. FIG. 15 is a cross-sectional view taken along the line XV-XV in FIG. The release lever 13 and the movable portion 14 are provided on the key ring 9. The movable portion 14 is displaceable with respect to the key ring 9 between a lock position and a release position which are separated from each other in the lateral direction Y of the portable device body 2. That is, the direction in which the movable portion 14 is displaced relative to the portable device body 2 and the direction in which the key ring 9 moves away from or approaches the assembled position of the portable device body 2 are different from each other. Further, a release lever 13 is fixed to the movable portion 14. Thus, the release lever 13 is displaced with respect to the key ring 9 integrally with the movable portion 14. The operation portion 131 of the release lever 13 is displaced in the lever opening 91 along the lateral direction Y of the portable device body 2 by the displacement of the movable portion 14 with respect to the key ring 9.

  The spring 15 is compressed between a first projection 21 which is a first stopper provided on the movable portion 14 and a second projection 22 which is a second stopper provided on the end face of the main body 7. It is arranged in the state. Thereby, the spring 15 biases the movable portion 14 to the lock position.

  The holding mechanism 16 holds the key ring 9 in the assembled position of the portable device body 2 when the movable portion 14 is in the lock position. Further, the holding mechanism unit 16 releases the holding of the key ring 9 by the displacement of the movable portion 14 from the lock position to the release position.

  The first hook 161 of the holding mechanism 16 is displaced integrally with the movable portion 14 along the short direction Y of the portable device body 2. The second hook 162 of the holding mechanism 16 is provided on the end face of the main body 7. When the key ring 9 is in the assembled position, the first hook 161 is hooked on the second hook 162 when the movable portion 14 reaches the lock position. This prevents displacement of the key ring 9 in the direction away from the assembly position.

  The release mechanism portion 17 displaces the key ring 9 in a direction in which the key ring 9 is released from the assembly position by the displacement of the movable portion 14 from the lock position to the release position. That is, the release mechanism section 17 displaces the key ring 9 from the assembly position in the longitudinal direction X different from the lateral direction Y in which the movable section 14 is displaced by the displacement of the movable section 14 from the lock position to the release position. The first guide portion 171 of the release mechanism portion 17 is displaced integrally with the movable portion 14 along the short direction Y of the portable device body 2. The first tapered surface 171 a formed in the first guide portion 171 is inclined with respect to the direction in which the movable portion 14 is displaced, that is, the lateral direction Y of the portable device body 2. The first tapered surface 171 a is also inclined with respect to the direction in which the key ring 9 is out of the assembly position, ie, the longitudinal direction X of the portable device body 2.

  The second guide portion 172 of the release mechanism 17 is provided on the end face of the main body 7. The second tapered surface 172a formed in the second guide portion 172 is inclined with respect to the longitudinal direction X and the lateral direction Y of the portable device body 2 in accordance with the inclination of the first tapered surface 171a. In the state where the key ring 9 is disposed at the assembly position, when the movable portion 14 reaches the lock position, the first guide portion 171 is separated from the second guide portion 172, as shown in FIG. When the movable portion 14 is displaced from the lock position toward the release position, the key ring 9 is displaced in a direction out of the assembly position of the portable device body 2 while the second guide portion 172 is guided by the first guide portion 171. Be done.

  In the storage space 12, a protrusion 185 is provided which bulges from the main body 7 in the thickness direction Z of the portable device body 2. Thus, the dimension in the thickness direction Z of the storage space 12 at the position of the protrusion 185 is narrower than the dimension in the thickness direction Z of the storage space 12 at a position other than the location of the protrusion 185, as shown in FIG. It has become. When the emergency key 5 is stored in the storage space 12, the tip of the emergency key 5 is press-fit between the first cover 3 and the projection 185. In a state where the tip of emergency key 5 is press-fit between first cover 3 and projection 185, the distance between projection 185 and emergency key 5 and between first cover 3 and emergency key 5 Frictional force is generated in each of them. The key ring 9 is displaced in the direction away from the assembled position of the portable device body 2 and in the direction approaching the assembled position of the portable device body 2, the projecting portion 185 and the first cover 3 and the emergency respectively. The frictional force generated by the contact with the key 5 is given as a resistance. That is, the resistance generating unit 18 that generates a resistance to the key ring 9 includes the emergency key 5 as a first resistance member. Moreover, the resistance force generation part 18 has the protrusion part 185 as a 2nd resistance member. In this example, the key ring 9 which is a detachable member is a first component, and the portable device body 2 is a second component. The other configuration is the same as that of the first embodiment.

  Next, an operation procedure for removing the emergency key 5 from the portable device 1 will be described. In the state where the key ring 9 is disposed at the assembled position of the portable device body 2, the tip of the emergency key 5 is press-fit between the protrusion 185 and the first cover 3. As a result, a resistance is given to the displacement of the key ring 9 in the direction out of the assembly position. When the key ring 9 is held at the assembled position of the portable device body 2 by the mounting and demounting mechanism 6, the movable portion 14 has reached the locked position by the force of the spring 15, as shown in FIG. Hook 161 is hooked on the second hook 162. Thereby, the displacement of the key ring 9 in the direction out of the assembled position of the portable device body 2 is prevented.

  When removing the emergency key 5 from the portable device 1, first, the operation unit 131 is operated in the direction of arrow C in FIG. 16. As a result, the movable portion 14 is displaced from the lock position toward the release position against the force of the spring 15.

  When the movable portion 14 is displaced from the lock position toward the release position, the first hook 161 disengages from the second hook 162. Thereafter, as shown in FIG. 16, the first tapered surface 171 a of the first guide portion 171 contacts the second tapered surface 172 a of the second guide portion 172.

  Thereafter, when the operating portion 131 is further operated in the direction of the arrow C in FIG. 16, the movable portion 14 is further displaced toward the release position against the force of the spring 15. Thus, the first guide portion 171 is displaced along the second tapered surface 172 a of the second guide portion 172. As a result, the key ring 9 is displaced in the direction away from the assembled position of the portable device body 2, that is, in the direction of the arrow P5 in FIG. At this time, the key ring 9 receives the frictional force between the emergency key 5 and the protrusion 185 and the frictional force between the emergency key 5 and the first cover 3 as a resistive force, and assembles the portable device body 2. It is displaced in the direction out of position.

  Thereafter, the movable portion 14 reaches the release position by further operating the operation portion 131 in the direction of the arrow C in FIG. As a result, as shown in FIG. 17, the emergency key 5 is disengaged from between the protrusion 185 and the first cover 3. When the key ring 9 is displaced toward the assembled position of the portable device body 2, the emergency key 5 comes in contact with the projection 185 and the first cover 3 again, and resistance is given to the key ring 9 again. As a result, the key ring 9 does not easily return to the assembled position of the portable device body 2.

  After that, when the operator releases the operation unit 131, the movable unit 14 is automatically displaced from the release position toward the lock position while the operation unit 131 is displaced in the direction of arrow D in FIG. Be done. At this time, since the position of the key ring 9 is shifted from the assembly position, as shown in FIG. 18, the first contact surface 161 a of the first hook 161 is on the second contact surface 162 a of the second hook 162. Contact.

  Thereafter, when the movable portion 14 is further displaced from the release position toward the lock position by the force of the spring 15, in the same manner as in the first embodiment, the first contact surface 161a is along the second contact surface 162a. While being guided, the first hook 161 is pushed by the second hook 162 in the direction in which the key ring 9 is removed from the assembled position of the portable device body 2, that is, in the direction of arrow P5 in FIG. As a result, the key ring 9 is further displaced in the direction away from the assembled position of the portable device body 2. After this, the movable portion 14 reaches the lock position. Thereby, the emergency key 5 can be removed from the portable device body 2.

  When the emergency key 5 is stored in the portable device 1 after using the emergency key 5, the key ring 9 is moved toward the assembly position of the portable device body 2 with the emergency key 5 inserted from the opening of the storage space 12. Push in At this time, the tip of the emergency key 5 is press-fitted between the first cover 3 and the projection 185. As a result, the key ring 9 is displaced toward the assembly position while receiving the frictional force generated between each of the first cover 3 and the projection 185 and the emergency key 5 as a resistive force. When the key ring 9 reaches the assembled position of the portable device body 2, the first hook 161 is automatically hooked on the second hook 162 as in the first embodiment. Thereby, the key ring 9 is held at the assembly position. When the key ring 9 is held in the assembled position, the opening of the storage space 12 is closed by the key ring 9. Thereby, the emergency key 5 is stored in the storage space 12.

  In such a portable device 1, when the key ring 9 is displaced in a direction approaching the assembly position of the portable device body 2, the emergency key 5 fixed to the key ring 9, the protrusion 185 and the first cover 3 And when they come into contact with each other, a frictional force is generated, which is applied to the key ring 9 as a resistive force. Therefore, the emergency key 5 can be used also as a component of the resistance generating unit 18, and it becomes unnecessary to provide the key ring 9 with a dedicated member for generating the frictional force. Thereby, simplification of the shape of the key ring 9 can be achieved. Further, since the emergency key 5 is integrated with the key ring 9, the emergency key 5 can be simultaneously removed from the portable device body 2 by removing the key ring 9 from the portable device body 2. For this reason, it is possible to further reliably reduce the time and effort when removing the emergency key 5 from the portable device main body 2.

  Further, the movable portion 14 is fixed to the release lever 13. For this reason, the operating force of the release lever 13 can be more reliably transmitted to the movable portion 14. Thereby, the key ring 9 can be more reliably removed from the portable device body 2. Further, the installation space of the release lever 13 and the movable portion 14 can be reduced. Thus, the portable device 1 can be miniaturized.

  In the above example, although the resistance force that the resistance generation unit 18 applies to the key ring 9 is the friction force between each of the protrusion 185 and the first cover 3 and the emergency key 5, It is not limited. For example, a resistance spring may be disposed in the storage space 12 and the resistance spring may be compressed by the emergency key 5 when inserted into the storage space 12. Also in this case, when the key ring 9 is displaced in the direction approaching the assembly position, the elastic restoring force of the resistance spring can be applied to the key ring 9 as a resistive force.

  Further, in the above-described example, the movable portion 14 provided on the key ring 9 which is a detachable member is fixed to the release lever 13. However, the movable portion 14 of the first embodiment provided in the portable device body 2 may be fixed to the release lever 13.
