  In the present invention, in a state where the insertion portion of the mechanical key portion is housed in the case, the first member is positioned adjacent to the opening of the battery housing portion in the axial direction of the battery housing portion. Therefore, in a state where the insertion portion of the mechanical key portion is accommodated in the case, the battery cannot be visually recognized, and when the lid portion that covers the battery accommodation portion is provided, the lid portion is also visually recognized. I can't.

  On the other hand, in a state where the insertion part of the mechanical key part is not accommodated in the case, the first member is not positioned in the axial direction of the battery accommodation part. Therefore, in the state where the insertion part of the mechanical key part is not accommodated in the case, when there is a battery or a cover part, the cover part can be visually recognized.

  In the configuration of Patent Document 1, since the battery cannot be visually recognized when the mechanical key is used, the motivation to replace the battery is weak. On the other hand, in this invention, when using a mechanical key, a battery or a cover part can be visually recognized. In addition, the battery or the battery lid cannot be visually recognized at the normal time when locking / unlocking is performed using the wireless transmission unit.

  A battery or a battery lid that cannot be visually recognized normally can be visually recognized by using a mechanical key, so that attention is directed to the battery or the battery lid. Therefore, it is difficult for the user to forget to replace the battery.

  In the second aspect of the present invention, the mechanical key portion (10) is separable from the case (20), is connected to the insertion portion, and is held by a user when the insertion portion is inserted into the key cylinder ( 11), the first member is a mechanical key portion, and the battery accommodating portion (14) is provided in the grip portion.

It is formed on the surface (322a) facing the part.

  Generally, when a person moves an object while holding it in his hand, the user performs a moving operation in a direction in which the object can be seen. Therefore, when separating the mechanical key part from the case, it is considered that the user often moves the mechanical key part in a direction in which the mechanical key part can be seen. In the present invention, since the battery housing part is formed facing the grip part of the mechanical key part, if the user moves the mechanical key part in a direction in which the grip part can be seen, The person is highly likely to visually recognize the battery housing part or the lid that covers the battery housing part. This makes it more difficult for the user to forget to replace the battery.

  Moreover, since the battery accommodating part is formed in the protruding part which is a part of the case, both the battery and the wireless transmission part are provided in the case. Therefore, unlike the case where the battery is provided in the mechanical key portion, it is not necessary to provide a terminal for electrically connecting the mechanical key portion and the case.

  In the invention according to claim 5, the grip portion of the mechanical key portion closes the opening of the battery accommodating portion in a state where the insertion portion of the mechanical key portion is accommodated in the case main body portion.

  Even in this configuration, by removing the insertion part of the remote control key part from the case main body part, the battery housing part is simultaneously in a state where the lid is removed. Therefore, since the battery can be visually recognized, it is difficult to forget to replace the battery.

In the invention according to claim 6, the insertion portion of the mechanical key portion (410) can be translated in the longitudinal direction and protruded from the case (420) and accommodated in the case.
The mechanical key portion is connected to the insertion portion, and includes an operation portion (411) to which the user applies an operation force when the insertion portion is translated with respect to the case.
The case is in contact with the operation portion with the insertion portion of the mechanical key portion protruding from the case, and the contact portion that prevents the insertion portion of the mechanical key portion from moving further away from the case ( 421),

  In the present invention, the battery housing portion is provided at a position in the case where the insertion portion of the mechanical key portion protrudes from the case and does not face the operation portion. By projecting the insertion portion from the case, at the same time, when the battery housing portion or the lid portion that closes the battery housing portion is provided, the lid portion can be exposed.

  In the present invention, the case includes a contact portion that contacts the operation portion in a state where the insertion portion of the mechanical key portion protrudes from the case. In this state, the mechanical key portion is further prevented from moving in a direction away from the case. Therefore, in the present invention, the mechanical key portion is not separated from the case. Therefore, it is possible to prevent only the mechanical key from being lost.

  Further, since the mechanical key portion is not separated from the case, the case can be used as a gripping portion of the mechanical key portion in a state where the insertion portion of the mechanical key portion is exposed from the case.

  According to the seventh aspect of the invention, the transparent key portion (16) is provided which is exposed in a state where the insertion portion of the mechanical key portion is not accommodated in the case and closes the opening of the battery accommodating portion.

  According to the present invention, since the lid portion is provided, it is possible to prevent the battery from dropping from the battery housing portion in a state where the insertion portion of the mechanical key portion is not housed in the case. Moreover, since the lid portion is transparent, the battery accommodated in the battery accommodating portion can be visually recognized through the lid portion. Therefore, it can also be suppressed that the effect of making it difficult to forget to replace the battery is reduced.

  According to the eighth aspect of the present invention, the mechanical key portion is exposed in a state where the insertion portion is not accommodated in the case, and includes a lid portion (17) that closes the opening of the battery accommodation portion, and the lid portion is urged to replace the battery. Has been.

<First Embodiment>
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a side view of a remote control key 1 according to the first embodiment. As shown in FIG. 1, the remote control key 1 of the first embodiment includes a mechanical key portion 10 and a case 20. The remote control key 1 of this embodiment is a device provided in the security system, and transmits an unlocking / unlocking signal to a host device provided in the security system.

  The mechanical key part 10 includes a grip part 11 and an insertion part 12. The shape of the holding part 11 is a rectangular parallelepiped shape. The insertion portion 12 is connected to the grip portion 11 and protrudes from one side surface 11a of the grip portion 11 perpendicularly to the side surface 11a. This insertion portion 12 is inserted into a key cylinder provided in the host device or other predetermined device to lock and release.

  A terminal 13 is also provided on the side surface 11a where the insertion portion 12 is provided. As shown in FIG. 2, two terminals 13 are provided. Further, a battery housing portion 14 is formed on the back surface 11 b of the grip portion 11.

  The battery housing part 14 is a bottomed hole that opens to the back surface 11 b of the gripping part 11, and a button type battery for supplying power to the battery housing part 14 to the wireless transmission part 23 provided in the case 20. (Hereinafter simply referred to as battery) 15 is accommodated. Therefore, the battery housing part 14 is a substantially disk-shaped space, and the axial direction of the battery housing part 14 substantially coincides with the axis of the battery 15 housed in the battery housing part 14.

  The battery 15 and the two terminals 13 are electrically connected inside the grip portion 11. In addition, since the mechanical key part 10 is equipped with the battery accommodating part 14, in 1st Embodiment, the case 20 becomes the side which is not equipped with the battery accommodating part 14, ie, a 1st member.

  The case 20 includes a case main body portion 21 and a protruding portion 22. The case main body 21 has a rectangular parallelepiped shape, and the protruding portion 22 is a flat plate protruding vertically from the side surface 21 a into which the insertion portion 12 of the mechanical key portion 10 is inserted in the case main body 21. The protruding portion 22 has a front surface 22 a that faces the back surface 11 b of the grip portion 11, and the back surface 22 b forms the same plane as the back surface 21 b of the case main body portion 21. The front surface 22 a and the back surface 22 b of the protruding portion 22 are a pair of surfaces having the largest area in the protruding portion 22.

  Inside the case main body portion 21, a wireless transmission portion 23 and an accommodation hole portion 24 are formed. A terminal 25 is provided on the side surface 21 a of the case body 21. Two terminals 25 are provided as shown in FIG.

  When the user operates a button provided on the remote control key 1, the wireless transmission unit 23 wirelessly transmits a locking / unlocking signal.

  The accommodation hole portion 24 is a longitudinal hole that accommodates the insertion portion 12 of the mechanical key portion 10, and the opening of the accommodation hole portion 24 is formed in the side surface 21 a of the case main body portion 21.

  As shown in FIG. 2, in the first embodiment, the mechanical key portion 10 does not have the lid of the battery housing portion 14, and the battery 15 is exposed when the mechanical key portion 10 is separated from the case 20. It becomes. Moreover, as shown in FIG. 3, the protrusion part 22 with which the case 20 is provided is a shape from which a planar view becomes a rectangle.

  As shown in FIG. 4, in a state where the insertion portion 12 of the mechanical key portion 10 is accommodated in the accommodation hole portion 24 of the case 20 (hereinafter, key accommodation state), the side surface 11 a of the grip portion 11 of the mechanical key portion 10 and The side surface 21a of the case main body 21 is in contact with each other, and the terminals 13 and 25 formed on the side surfaces 11a and 21a are also in contact with each other.

  Further, in the key storage state, the back surface 11 b of the grip portion 11 and the front surface 22 a of the protruding portion 22 of the case 20 are also in contact. Therefore, the protruding portion 22 of the case 20 functions as a lid for the battery housing portion 14 formed in the grip portion 11.

<Effects of First Embodiment>
As described above, according to the first embodiment described above, in the key housing state shown in FIG. 4, the protruding portion 22 of the case 20 is adjacent to the opening of the battery housing portion 14, in other words, the axial direction of the battery housing portion 14. For example, the protruding portion 22 of the case 20 closes the opening of the battery accommodating portion 14. Therefore, the battery 15 cannot be visually recognized in the key accommodation state.

  On the other hand, in a state where the insertion portion 12 of the mechanical key portion 10 is not accommodated in the case 20 (hereinafter referred to as a key removal state), the protruding portion 22 of the case 20 is not positioned in the axial direction of the battery accommodating portion 14 and protrudes. The part 22 does not block the opening of the battery housing part 14. Therefore, the battery 15 can be visually recognized in the key removal state.

  In the configuration of Patent Document 1, since the battery cannot be visually recognized when using the mechanical key, the motivation to replace the battery is weak. On the other hand, in this embodiment, the battery 15 can be visually recognized when the key is taken out. Moreover, the battery 15 cannot be visually recognized in the key accommodation state, which is a normal state in which the wireless transmission unit 23 is used for locking and unlocking.

  The battery 15 that cannot be visually recognized at normal times becomes visible when the key is taken out, so that attention is directed to the battery 15. Therefore, it is difficult for the user to forget to replace the battery.

  Further, in the present embodiment, the protruding portion 22 of the case 20 functions as a lid for the battery housing portion 14, and when the key is taken out, the lid for the battery housing portion 14 is automatically removed. This also makes it difficult to forget to replace the battery.

  In the key removal state, the user holds the grip portion 11 in his / her hand in order to insert and insert the insertion portion 12 into the key cylinder. Since the battery accommodating portion 14 is formed in the grip portion 11, the user performs a locking / unlocking operation while pressing the battery 15 in order to prevent the battery 15 from falling off. Therefore, it is particularly easy to pay attention to the battery 15. Moreover, when it is troublesome to hold down the battery 15, it is also conceivable to take out the battery 15 from the battery housing part 14 and perform a locking / unlocking operation. The operation of taking out the battery 15 whose voltage has dropped is part of the battery exchange operation. Therefore, when the battery 15 is taken out from the battery housing portion 14 and the unlocking operation is performed, it is difficult to forget to replace the battery.

Second Embodiment
Next, a second embodiment will be described. In the following description of the second embodiment, elements having the same reference numerals as those used so far are the same as elements having the same reference numerals in the previous embodiments unless otherwise specified. Further, when only a part of the configuration is described, the above-described embodiment can be applied to the other parts of the configuration.

  FIG. 5 shows a remote control key 100 of the second embodiment. The remote control key 100 of the second embodiment includes the same case 20 as that of the first embodiment. Moreover, the mechanical key part 110 differs in the structure of the holding part 111 from the holding part 11 of 1st Embodiment.

  The gripper 111 has the same outer shape as the gripper 11 of the first embodiment. The difference between the grip portion 111 and the grip portion 11 of the first embodiment is that the battery housing portion 14 is formed on the inner side in the thickness direction of the grip portion 111 than the first embodiment, and the opening of the battery housing portion 14 is opened. It is a point provided with the cover part 16 to close. In the grip portion 111 of the second embodiment, the position of the battery housing portion 14 is formed on the inner side in the thickness direction of the grip portion 111 than in the first embodiment by the thickness of the lid portion 16.

  The lid portion 16 is made of a colorless and transparent resin. Therefore, as shown in FIG. 6, the battery 15 can be visually recognized through the lid portion 16 in the key removal state.

<Effects of Second Embodiment>
In this 2nd Embodiment, since the cover part 16 is provided, it can prevent that the battery 15 falls from the battery accommodating part 14 in the key extraction state. Moreover, since the lid portion 16 is transparent, the battery 15 can be visually recognized through the lid portion 16. Therefore, it can also be suppressed that the effect of making it difficult to forget to replace the battery is reduced due to the presence of the lid portion 16.

<Third Embodiment>
FIG. 7 shows a mechanical key unit 210 provided in the remote control key of the third embodiment. The mechanical key part 210 of FIG. 7 includes a non-transparent lid part 17 instead of the transparent lid part 16 included in the mechanical key part 110 of the second embodiment. On the lid portion 17, “battery replacement required” is displayed as a display for prompting battery replacement.

  Since the lid portion 17 is opaque, the battery 15 cannot be visually recognized unless the lid portion 17 is removed, but it is difficult to forget to replace the battery because the characters “require battery replacement” are displayed on the lid portion 17. It can also be suppressed that the effect becomes lower. In addition, since the lid portion 17 is provided, it is possible to prevent the battery 15 from dropping out of the battery housing portion 14 in the key removal state.

<Fourth embodiment>
In the remote control key 300 of the fourth embodiment shown in FIG. 8, the grip portion 311 provided in the mechanical key portion 310 does not have an electrical configuration. In the remote control key 300 of the fourth embodiment, the case 320 includes a battery housing portion 321. Therefore, in the fourth embodiment, the mechanical key portion 310 is the first member.

  The battery housing portion 321 is formed to open on the surface 322 a of the protruding portion 322. The protruding portion 322 is thicker than the protruding portion 22 of the previous embodiments so that the battery housing portion 321 can be formed. And since the protrusion part 322 is thick, the thickness of the holding part 311 of the mechanical key part 310 is thinner than the holding part 11 of the previous embodiment.

  As shown in FIG. 9, the battery housing portion 321 is formed at the center of the surface 322 a of the protruding portion 322. Further, no lid is provided to close the battery housing portion 321, and the battery 15 is exposed in the key removal state shown in FIG. 9.

  In the key storage state shown in FIG. 10, the surface of the grip portion 311 that faces the surface 322a of the protruding portion 322 and the surface 322a are in contact with each other. Therefore, the grip portion 311 functions as a lid for the battery housing portion 321.

<Effects of Fourth Embodiment>
Even if the battery accommodating portion 321 is provided on the surface 322a of the protruding portion 322 of the case 320 as in the fourth embodiment, the battery 15 is hidden by the grip portion 311 and cannot be visually recognized in the key accommodating state. When the key is taken out, the grip portion 311 serving as the lid of the battery housing portion 321 is removed, and the battery 15 can be visually recognized. Therefore, it is difficult for the user to forget to replace the battery.

  In general, when a person moves an object while holding it in his hand, the user performs a moving operation in a direction in which the object can be seen. Therefore, when separating the mechanical key part 310 from the case 320, it is considered that the user often moves the mechanical key part 310 in a direction in which the mechanical key part 310 can be seen. Since the portion of the mechanical key portion 310 that can be visually recognized in the key accommodation state is the grip portion 311, it is considered that the mechanical key portion 310 is moved with the grip portion 311 facing upward.

  Since the battery housing portion 321 is formed so as to face the grip portion 311, when the user moves the mechanical key portion 310 in a direction in which the grip portion 311 can be seen, the user moves the mechanical key portion 310 and moves the user. Has a high possibility of visually recognizing the battery housing portion 321. This makes it more difficult for the user to forget to replace the battery.

  Further, since the battery housing portion 321 is formed in the protruding portion 322 which is a part of the case 320, both the battery 15 and the wireless transmission portion 23 are provided in the case 320. Therefore, unlike the case where the battery 15 is provided in the mechanical key portion 310, it is not necessary to provide terminals for electrically connecting the mechanical key portion 310 and the case 320.

<Fifth Embodiment>
FIG. 11 is a plan view of a remote control key 400 of the fifth embodiment, and FIG. 12 is a cross-sectional view taken along the line XII-XII of FIG. The states shown in FIGS. 11 and 12 are key accommodation states.

  The mechanical key part 410 includes an insertion part 12 and an operation part 411. The operation unit 411 is made of a non-transparent resin and includes a base 412 and a projection 413. The base portion 412 has a rectangular flat plate shape, and the insertion portion 12 protrudes from one end surface 412a.

  The convex portion 413 protrudes from the surface 412b of the base portion 412 along the end surface 412c facing the end surface 412a. An operation mark 414 indicating an operation direction is formed on the upper surface of the convex portion 413.

  The case 420 is a rectangular parallelepiped box, and an opening 422 that penetrates in the thickness direction of the upper plate 421 is formed in the upper plate 421 provided with the surface 420a of the case 420. In addition, a housing hole 423 having the upper plate portion 421 as a part of the inner wall surface is formed inside the case 420.

  The shape of the accommodation hole 423 is a shape that can accommodate a part of the insertion portion 12 of the mechanical key portion 410 and a portion of the base portion 412 of the operation portion 411 on the insertion portion 12 side. One end of the accommodation hole 423 opens to the end surface 420b of the case 420, and the other end communicates with the opening 422 of the upper plate portion 421.

  In the fifth embodiment, a battery accommodating portion 425 is formed on an inner bottom portion 424 that forms the inner wall surface of the accommodating hole 423 together with the upper plate portion 421, and the battery 15 is accommodated in the battery accommodating portion 425.

  In the key accommodation state in which the insertion portion 12 of the mechanical key portion 410 is accommodated in the accommodation hole 423, the operation portion 411 of the mechanical key portion 410 faces the battery accommodation portion 425, and the operation portion 411 corresponds to the battery accommodation portion 425. The opening is blocked. Therefore, in the key storage state, the battery 15 stored in the battery storage unit 425 cannot be visually recognized.

  One end of the accommodation hole 423 opens to the end surface 420b of the case 420, and the convex portion 413 of the operation unit 411 does not contact the end of the opening 422 in the key accommodation state. Further, the base portion 412 of the operation portion 411 has a width and a thickness that enter the accommodation hole 423. Therefore, when the user moves the convex portion 413 of the operation unit 411 in the direction of the insertion portion 12 of the mechanical key portion 410, the insertion portion 12 of the mechanical key portion 410 is translated in the longitudinal direction of the insertion portion 12. In this state, it protrudes from the case 420.

  The upper plate portion 421 of the case 420 functions as an abutting portion of claims. When the convex portion 413 of the operation portion 411 contacts the upper plate portion 421 of the case 420, the insertion portion 12 of the mechanical key portion 410 is moved. The length protruding from the case 420 is the maximum and does not move further away from the case 420. Hereinafter, a state in which the protrusion length of the insertion portion 12 of the mechanical key portion 410 is maximum is referred to as a key protrusion state.

  FIG. 13 is a plan view of the remote control key 400 in the key protruding state, and FIG. 14 is a cross-sectional view taken along the line XIV-XIV in FIG. In the key protruding state, the operation unit 411 does not face the battery housing unit 425, and therefore the battery housing unit 425 can be visually recognized from the outside.

<Effect of Fifth Embodiment>
In the remote control key 400 of the fifth embodiment, the battery housing portion 425 is provided in the case 420 at a position that does not face the operation portion 411 in the key protruding state. Therefore, the battery accommodating part 425 can be exposed at the same time by applying an operating force to the operating part 411 to bring the key into a protruding state.

  Further, in the key protruding state, the operation portion 411 is in contact with the upper plate portion 421, and the mechanical key portion 410 is further prevented from moving in a direction away from the case 420. Therefore, the mechanical key part 410 is not separated from the case 420. Therefore, it is possible to prevent only the mechanical key portion 410 from being lost.

  Further, since the mechanical key portion 410 is not separated from the case 420, the case 420 can be used as a gripping portion of the mechanical key portion 410 in a state where the insertion portion 12 of the mechanical key portion 410 is exposed from the case 420.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to the above-mentioned embodiment, The following modification is also contained in the technical scope of this invention, Furthermore, the summary other than the following is also included. Various modifications can be made without departing from the scope.
