[Modes for carrying out the invention]

[0010] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the embodiments described below, common elements are denoted by the same reference numerals, and redundant descriptions of common elements may be omitted. Note that the following embodiments and modifications are only a part of various embodiments of the present disclosure. In addition, the following embodiments and modifications can be variously changed according to design and the like as long as the object of the present disclosure can be achieved. Also, it is possible to appropriately combine the configurations of the modifications.

[0011] Each figure described in the present disclosure is a schematic diagram, and the ratio of the size and thickness of each component in each figure does not necessarily reflect the actual dimensional ratio.

[0012] Note that the "orthogonal (perpendicular)" as used in the present disclosure means not only a state where the angle between two entities is exactly 90 degrees, but also a state where the two entities intersect within a certain range of difference. That is, the angle between two orthogonal entities falls within a certain range of difference (for example, 10 degrees or less) with respect to 90 degrees. That is, the "orthogonal" as used in the present disclosure includes cases where the angle formed by two entities is 80 degrees or more and 100 degrees or less. Similarly, for the "parallel" as used in the present disclosure, it means not only a state where two entities do not strictly intersect, but also a state where the two entities are arranged within a certain range of difference. For example, the "parallel" as used in the present disclosure includes cases where the inclination of one with respect to the other is 10 degrees or less. That is, the "parallel" as used in the present disclosure includes cases where the angle formed by one and the other is -10 degrees or more and 10 degrees or less.

[0013] (Embodiment 1) (1) Overview First, the overview of the control system 1 according to Embodiment 1 will be described with reference to FIG. 1.

[0014] The control system 1 of Embodiment 1 includes a first acquisition unit 251, a second acquisition unit 252, an authentication unit 253, a restriction mechanism 21, a first control unit 254, and a second control unit 255.

[0015] The first acquisition unit 251 acquires first information which is biometric authentication information.

[0016] The second acquisition unit 252 acquires second information, which is information separate from the biometric authentication information.

[0017] The authentication unit 253 performs authentication processing using the first information acquired by the first acquisition unit 251.

[0018] The restriction mechanism 21 restricts the operation of the lever portion 3 (see Figure 2) of the crescent lock 2, rendering the lever portion 3 inoperable.

[0019] The first control unit 254 controls the restriction mechanism 21 to release the restriction when authentication is successful in the authentication process.

[0020] The second control unit 255 controls the limiting mechanism 21 to release the restriction based on the second information acquired by the second acquisition unit 252.

[0021] According to the control system 1 of Embodiment 1, the restriction on the operation of the lever 3 is released only when authentication using biometric authentication information is successful. In other words, since the lever 3 cannot be operated by anyone other than a person whose biometric authentication information has been registered in advance, the security function can be improved. Furthermore, according to the control system 1 of Embodiment 1, for example, by preventing the lever 3 from being operated by a child, it is possible to suppress the occurrence of problems such as a child falling or a child locking their parent out.

[0022] Furthermore, according to the control system 1 of Embodiment 1, it is also possible to release the restriction on the operation of the lever unit 3 based on second information, which is information separate from biometric information. For example, in the event of a disaster, it becomes possible to release the restriction on the operation of the lever unit 3 even for a person whose biometric authentication information has not been registered in advance, making it possible to operate the lever unit 3 more reliably.

[0023] In this disclosure, "disaster" may include, for example, fire, gas leak, earthquake, flood, etc.

[0024] (2) Details The detailed configuration of the control system 1 according to Embodiment 1 will be described below with reference to Figures 1 to 7.

[0025] Embodiment 1 assumes that the control system 1 is installed in a facility that is, for example, a detached house. In other words, in Embodiment 1, the user of the control system 1 is the resident of the detached house, etc. In this disclosure, "facility" includes residential facilities used for living purposes, as well as non-residential facilities such as shops (tenants), offices, welfare facilities, educational facilities, hospitals, and factories. Non-residential facilities also include restaurants, amusement parks, hotels, inns, kindergartens, nurseries, and community centers. In other words, the facility may be a residential facility such as an apartment building, or a non-residential facility such as an office building. Furthermore, the facility may also include facilities in which residential and non-residential facilities are mixed, for example, with shops on the lower floors and residential units on the upper floors.

[0026] Embodiment 1 assumes that the crescent lock 2, which functions as a control system 1, is installed on the interior side of a sliding window 10 in a detached house.

[0027] In the following description, the direction perpendicular to both the left-right and up-down directions is defined as the front-back direction. However, in this disclosure, "left-right direction" simply means the direction in which the lever portion 3 and the base portion 4 are aligned. In this disclosure, "front-back direction" simply means the direction in which the first window 11 and the second window 12 are aligned. In this disclosure, "up-down direction" simply means the direction perpendicular to both the left-right direction and the front-back direction. Note that in Embodiment 1, the "up-down direction" is the direction along the vertical direction. The descriptions of "left-right direction," "front-back direction," and "up-down direction" in this disclosure are not intended to limit the direction in which the crescent lock 2 can be used.

[0028] Furthermore, the direction from lever section 3 towards base section 4 is defined as "rightward," and the direction from base section 4 towards lever section 3 is defined as "leftward." The direction from first window 11 towards second window 12 is defined as "rearward," and the direction from second window 12 towards first window 11 is defined as "forward." Vertical downward is defined as "downward," and vertical upward is defined as "upward." Note that the arrows indicating each direction in the drawing are for illustrative purposes only and do not represent actual objects.

[0029] (2.1) Configuration of the control system The control system 1 is a system that can restrict the operation of the lever portion 3 of the crescent lock 2 and release the restriction on the operation of the lever portion 3 based on acquired biometric authentication information (i.e., first information). Furthermore, the control system 1 can also release the restriction on the operation of the lever portion 3 based on second information, which is information different from the biometric authentication information. The control system 1 of Embodiment 1 has two operating modes: an operation mode and a registration mode. The operation mode is an operating mode in which the operation of the lever portion 3 of the crescent lock 2 is restricted and the restriction on the operation of the lever portion 3 is released based on acquired biometric authentication information. The registration mode is an operating mode in which acquired biometric authentication information is registered or deleted. The operating mode can be switched, for example, by performing a predetermined operation on the biometric authentication sensor 22.

[0030] Furthermore, the control system 1 (or crescent lock 2) of Embodiment 1 has a first mode and a second mode as operating modes separate from the operation mode and the registration mode. More specifically, the control system 1 of Embodiment 1 has four operating modes: a first mode within the operation mode, a second mode within the operation mode, a first mode within the registration mode, and a second mode within the registration mode. The first mode is a mode in which the operation of the second acquisition unit 252 and the second control unit 255 is off, and the second mode is a mode in which the operation of the second acquisition unit 252 and the second control unit 255 is on.

[0031] As described above, the crescent tablet 2 of Embodiment 1 functions as a control system 1. In other words, the crescent tablet 2 of Embodiment 1 has all the components of the control system 1.

[0032] (2.2) Composition of Crescent Tablets As shown in Figure 2, the crescent lock 2 is installed on the sliding window 10. The sliding window 10 has a first window 11 and a second window 12. The first window 11 is located on the interior side of the second window 12. The first window 11 has a glass plate 111 and a left window frame 112. The second window 12 has a glass plate 121 and a right window frame 122. The left window frame 112 is the window frame corresponding to the left side of the glass plate 111. The right window frame 122 is the window frame corresponding to the right side of the glass plate 121. The left window frame 112 and the right window frame 122 overlap in the front-to-back direction when the sliding window 10 is closed. Note that a resin plate may be used instead of the glass plate 111, or a resin plate may be used instead of the glass plate 121. Note that in Embodiment 1, the sliding window 10 is shown as a sliding window on the right front, but the sliding window 10 may be a sliding window on the left front. In other words, while the crescent lock 2 in Embodiment 1 is configured to correspond to the sliding window on the front right, the crescent lock 2 may also be configured to correspond to the sliding window on the front left.

[0033] As shown in Figure 1, the crescent lock 2 comprises a restriction mechanism 21, a biometric authentication sensor 22, a display unit 23, a storage unit 24, a processing unit 25, a battery 26, a monitoring unit 27, an operation switching unit 28, and a release operation unit 6.

[0034] Furthermore, as shown in Figures 2 to 7, the crescent lock 2 comprises a lever portion 3 and a base portion 4.

[0035] The crescent receiver 5 is installed on the right window frame 122 of the second window 12 of the sliding window 10. The crescent receiver 5 has the shape of a rectangular plate bent into a J-shape (or U-shape). When installed on the right window frame 122, the crescent receiver 5 protrudes to the left from the right window frame 122, bends inward (forward), and protrudes to the right. When installed on the right window frame 122, the crescent receiver 5 is J-shaped (or U-shaped) in a plan view. When the crescent part 33 of the lever part 3 is passed through the bent part of the crescent receiver 5, the crescent lock 2 is locked. On the other hand, when the crescent part 33 of the lever part 3 is not passed through the bent part of the crescent receiver 5, the crescent lock 2 is unlocked.

[0036] The lever portion 3 is connected to the base portion 4 so as to be rotatable about the rotation axis Ax1 (see Figure 4). When the crescent lock 2 is installed on the sliding window 10, the rotation axis Ax1 is parallel in the left-right direction. When the restriction mechanism 21 is not in place, the lever portion 3 is configured to be rotatable between a first position and a second position in response to operation on the lever portion 3. The first position of the lever portion 3 is the position in which the crescent lock 2 is locked, and the second position of the lever portion 3 is the position in which the crescent lock 2 is unlocked.

[0037] The lever portion 3 has a lever base 31 and a lever 32. The lever base 31 and the lever 32 are formed in a box shape. The internal space of the lever base 31 and the internal space of the lever 32 are connected. The lever base 31 is connected to the base portion 4 so as to be rotatable about the rotation axis Ax1 (see Figure 4) when not restricted by the limiting mechanism 21. The lever 32 protrudes in one direction from one end of the lever base 31. In the crescent lock 2 of Embodiment 1, when the lever portion 3 is in the first position, the lever 32 protrudes upward from the lever base 31. Also, when the lever portion 3 is in the second position, the lever 32 protrudes downward from the lever base 31.

[0038] Furthermore, the lever portion 3 has a crescent portion 33. The crescent portion 33 is configured to rotate integrally with the lever base portion 31 about a rotation axis Ax1. The shape of the crescent portion 33 is like a rectangular plate bent into an arc. In a side view (or left side view) of the crescent lock 2 installed in the sliding window 10, the shape of the crescent portion 33 is semi-circular. When the lever portion 3 is in the first position, the crescent portion 33 passes through the bent portion of the crescent receiver 5. When the lever portion 3 is in the second position, the crescent portion 33 does not pass through the bent portion of the crescent receiver 5.

[0039] The base portion 4 is formed in the shape of a rectangular plate. The base portion 4 is installed on the left window frame 112 of the first window 11 of the sliding window 10 so that the thickness direction of the base portion 4 is aligned with the left-right direction. More specifically, the base portion 4 is installed on the left surface of the left window frame 112 so that the longitudinal direction of the base portion 4 is aligned with the up-down direction. The base portion 4 is installed on the left window frame 112 by means of screws 42 (see Figure 4), for example.

[0040] The base portion 4 has a connecting portion 41 (see Figure 7). The connecting portion 41 is formed in the center of the base portion 4. The lever portion 3 is connected to the connecting portion 41 in such a way that it can rotate around the rotation axis Ax1.

[0041] The limiting mechanism 21 restricts the operation of the lever portion 3 of the crescent lock 2, thereby preventing the lever portion 3 from being operated. Figures 5 and 6 are plan views of the crescent lock 2 when the lever portion 3 is in the first position. In Figures 5 and 6, a portion of the outer shape of the lever portion 3 is shown by a dashed line. As shown in Figures 5 and 6, the limiting mechanism 21 of Embodiment 1 includes a pin 211, an actuator 214, a disc 215, a protrusion 217, a first plate portion 218, a spring 219, and a second plate portion 220. In Embodiment 1, the pin 211, actuator 214, disc 215, protrusion 217, first plate portion 218, spring 219, and second plate portion 220 are provided on the lever portion 3. More specifically, at least a portion of the pin 211, the actuator 214, the disc 215, the protrusion 217, the first plate portion 218, the spring 219, and the second plate portion 220 are housed in the internal space of the lever 32 of the lever portion 3. However, at least a portion of the pin 211, the actuator 214, the disc 215, the protrusion 217, the first plate portion 218, the spring 219, and the second plate portion 220 may be housed in the internal space of the lever base 31.

[0042] The actuator 214 is connected to the disc 215. The actuator 214 is positioned closer to the lever base 31 than the disc 215. The actuator 214 has a motor. The motor is, for example, a DC motor. The motor converts power supplied from the battery 26 into rotational force (torque) on the motor shaft. In Embodiment 1, the power source for the motor is a primary battery housed in the internal space of the lever portion 3. However, the power source for the motor is not limited to a primary battery, but may be a secondary battery or a solar cell, etc. Also, the power source for the motor does not have to be housed in the internal space of the lever portion 3.

[0043] The actuator 214 further includes a transmission mechanism. The transmission mechanism rotates the disc 215 by transmitting the rotational force of the motor shaft to the disc 215.

[0044] The disc 215 is formed in a disc-shaped plate form. The disc 215 is positioned closer to the tip of the lever 32 than the actuator 214. The thickness direction of the disc 215 is perpendicular to the axial direction of the pin 211.

[0045] The projection 217 is formed in a cylindrical shape. The projection 217 protrudes from the main surface of the disc 215 toward the tip of the lever 32, along the thickness direction of the disc 215. The projection 217 rotates around the center of the disc 215 as the disc 215 rotates. More specifically, the projection 217 rotates between a first position and a second position as the disc 215 rotates. The first position corresponds to the right end of the projection 217's range of motion (see Figure 5), and the second position corresponds to the left end of the projection 217's range of motion (see Figure 6).

[0046] The first plate portion 218 is formed in a rectangular plate shape. The first plate portion 218 is connected to the pin 211. The thickness direction of the first plate portion 218 is aligned with the axial direction (left-right direction) of the pin 211. The first plate portion 218 operates integrally with the pin 211. The first plate portion 218 and the pin 211 may be formed integrally. The first plate portion 218 receives an elastic force from the spring 219 in the rightward direction, causing it to come into contact with the left end of the protrusion 217.

[0047] The second plate portion 220 is formed in a rectangular plate shape. The second plate portion 220 is positioned to the left of the first plate portion 218 so as to face the first plate portion 218 in the left-right direction. The second plate portion 220 is fixed to the lever 32. The second plate portion 220 has a through hole. The shape of the through hole matches the outer shape of the left end of the pin 211, and the left end of the pin 211 is inserted into the through hole in the second plate portion 220.

[0048] Spring 219 is a coil spring. Spring 219 is positioned between the first plate portion 218 and the second plate portion 220. A pin 211 is passed through spring 219.

[0049] The pin 211 is formed in a cylindrical shape. The axial direction of the pin 211 is aligned with the left-right direction. Furthermore, the outer shape (or outline) of the cross-section of the left end portion of the pin 211, including the left end, includes a straight section. In other words, the distance from the center of the cross-section to one point on the outline of the left end portion of the pin 211 may differ from the distance from the center of the cross-section to another point on the outline of the outline. As a result, the pin 211 is supported by the second plate portion 220 without rotating about its axial direction.

[0050] The pin 211 is configured to be displaceable between a first position and a second position in the left-right direction. The position of the pin 211 in the left-right direction is determined by the projection 217. When the projection 217 is in the first position, the pin 211 is in the first position (see Figure 5). When the projection 217 is in the second position, the pin 211 is in the second position (see Figure 6). The first position of the pin 211 is the position where the right end of the pin 211 protrudes furthest towards the base portion 4. In other words, when the pin 211 is in the first position, the state of the pin 211 is the protruding state. The second position of the pin 211 is the position where the right end of the pin 211 is furthest away from the base portion 4. In other words, when the pin 211 is in the second position, the state of the pin 211 is the non-protruding state.

[0051] Furthermore, the pin 211 of Embodiment 1 is configured to be able to be pushed back against the elastic force of the spring 219 in the opposite direction (i.e., left) to the protruding direction (i.e., right). When the pin 211 is pushed back in the opposite direction to the protruding direction, the first plate portion 218 and the protruding portion 217 become non-contact.

[0052] As shown in Figure 7, the limiting mechanism 21 of Embodiment 1 further has two holes 212 and two grooves 213. The two holes 212 and the two grooves 213 are provided in the base portion 4.

[0053] One of the two holes 212 (or the first hole) is located in a position corresponding to the first position of the lever portion 3. Specifically, the first hole is located in a position corresponding to the pin 211 when the lever portion 3 is in the first position. More specifically, the first hole is located in a position that overlaps with the pin 211 in a side view when the lever portion 3 is in the first position. When the lever portion 3 is in the first position (i.e., when the crescent lock 2 is locked), the pin 211 protrudes, causing the pin 211 to be inserted into the first hole, making it impossible to rotate the lever portion 3.

[0054] The other of the two holes 212 (or the second hole) is located at a position corresponding to the second position of the lever portion 3. Specifically, the other of the two holes 212 is located at a position corresponding to the pin 211 when the lever portion 3 is in the second position. More specifically, the other of the two holes 212 is located at a position that overlaps with the pin 211 in a side view when the lever portion 3 is in the second position. When the lever portion 3 is in the second position (i.e., when the crescent lock 2 is unlocked), the pin 211 protrudes, causing the pin 211 to be inserted into the second hole, making it impossible to rotate the lever portion 3.

[0055] In other words, the restriction mechanism 21 of Embodiment 1 is configured to restrict the operation of the lever 3 whether the crescent lock 2 is locked or unlocked. This allows for more reliable restriction of the operation of the lever 3, improving security and preventing problems such as children falling or children locking their parents out.

[0056] The two grooves 213 correspond one-to-one with the two holes 212. In Embodiment 1, the grooves 213 are formed in front of the corresponding holes 212. The grooves 213 extend from the corresponding holes 212 to the front end of the base portion 4. The shape of the grooves 213 follows the movement path of the pin 211 when the lever portion 3 rotates around the rotation axis Ax1. Furthermore, the grooves 213 are formed to become shallower as they approach the corresponding holes 212, that is, as they approach the rear end of the grooves 213. Also, the depth of the front end of the grooves 213 is such that the tip of the pin 211 does not touch the groove when the pin 211 is in the first position.

[0057] As described later, the first control unit 254 moves the pin 211 from the protruding state to the protruding state, and after a first predetermined period (e.g., about 10 seconds) or a second predetermined period (e.g., about 10 minutes) has elapsed since moving the pin 211 from the protruding state to the non-protruding state, it moves the pin 211 from the non-protruding state to the protruding state. Therefore, even when the position of the lever portion 3 is between the first position and the second position, the pin 211 may be in the protruding state. The groove 213 is configured to push back the protruding pin 211 and guide it into the corresponding hole 212, even when the position of the lever portion 3 is between the first position and the second position. As a result, even if the pin 211 is in the protruding state when the position of the lever portion 3 is between the first position and the second position, the operation of the lever portion 3 can be restricted by displacing the lever portion 3 to the first position or the second position, thus more reliably restricting the operation of the lever portion 3. Therefore, the control system 1 of the embodiment can further improve the security function.

[0058] The biometric authentication sensor 22 acquires biometric authentication information from a person (or user). The biometric authentication sensor 22 outputs the acquired biometric authentication information to the first acquisition unit 251. The biometric authentication sensor 22 of Embodiment 1 is a fingerprint authentication sensor that acquires fingerprint information as biometric authentication information from a person's fingertip. According to the control system 1 of Embodiment 1, biometric authentication information can be acquired in a simple way for the user, by touching the biometric authentication sensor 22 with a fingertip, thus improving convenience for the user.

[0059] The biometric authentication sensor 22 is housed in the internal space of the lever base 31, so as to be exposed through the through hole 311 of the lever base 31 of the lever portion 3. In Embodiment 1, the biometric authentication sensor 22 is exposed from the lever base 31 in a left side view when the crescent lock 2 is installed in the sliding window 10. The biometric authentication sensor 22 is also mounted on the rotation axis Ax1 of the lever portion 3.

[0060] The crescent lock 2 of Embodiment 1 includes a release operation unit 6A that functions as a release operation unit 6. The release operation unit 6A is a touch sensor that accepts human touch operation. In this embodiment, the release operation unit 6A is integrally configured with a biometric authentication sensor 22. The release operation unit 6A outputs a signal corresponding to the touch operation to the second acquisition unit 252 of the processing unit 25.

[0061] The display unit 23 notifies the user of the operating status of the control system 1. The "operating status of the control system 1" includes the status of the restriction on the operation of the lever unit 3, the result of the authentication process, the operating mode of the control system 1, or the remaining capacity of the battery 26. In other words, the display unit 23 notifies the user whether the operation of the lever unit 3 is restricted, whether the authentication process was successful, whether the operating mode is the operation mode or the registration mode, and how much capacity remains in the battery 26. This allows the user to be notified of the operating status of the control system 1.

[0062] The display unit 23 in Embodiment 1 is, for example, an LED (Light Emitting Diode). However, the display unit 23 may also be an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display.

[0063] The display unit 23 is housed in the internal space of the lever base 31, and is exposed through the through hole 312 of the lever base 31 of the lever unit 3. In Embodiment 1, the display unit 23 is exposed from the lever base 31 in a left side view when the crescent lock 2 is installed in the sliding window 10. However, the display unit 23 may be installed so as to surround the biometric authentication sensor 22 in a left side view, or it may be installed at the tip of the lever 32 of the lever unit 3. In addition, there may be multiple display units 23.

[0064] The storage unit 24 includes, for example, a semiconductor memory such as ROM (Read Only Memory) or EEPROM (Electrically Erasable Programmable Read Only Memory). The storage unit 24 stores fingerprint information as biometric authentication information of a user that has been registered in advance in registration mode. For example, the storage unit 24 is provided in the internal space of the lever base 31 of the lever unit 3.

[0065] The battery 26 is a primary battery. However, the battery 26 may be a secondary battery. In Embodiment 1, the battery 26 is housed in the internal space of the lever portion 3. The battery 26 supplies power to the actuator 214 of the limiting mechanism 21, the biometric authentication sensor 22 and the release operation unit 6A, the display unit 23, the storage unit 24, and the processing unit 25 monitoring unit 27.

[0066] The monitoring unit 27 monitors the remaining capacity of the battery 26. The monitoring unit 27 outputs power information indicating the remaining capacity of the battery 26 to the second acquisition unit 252 of the processing unit 25. For example, the monitoring unit 27 measures and outputs the battery voltage as power information indicating the remaining capacity. Generally, batteries have the property that the battery voltage decreases as the remaining capacity decreases, so the remaining capacity can be estimated by measuring the battery voltage. Alternatively, the monitoring unit 27 may measure and output the change in capacity by integrating the discharge current over time as power information indicating the remaining capacity. The remaining capacity can be estimated by subtracting the measured change in capacity from the battery capacity before discharge.

[0067] The operation switching unit 28 is a switching unit that switches the operation of the second acquisition unit 252 and the second control unit 255 on or off. As shown in Figure 4, the operation switching unit 28 is provided on the front of the base unit 4. The operation switching unit 28 is a switch configured to slide in the vertical direction. The operation switching unit 28 is configured to slide so as to be displaceable in the vertical direction between a first position (e.g., upper end) and a second position (e.g., lower end). For example, when the operation switching unit 28 is in the first position, the operation of the second acquisition unit 252 and the second control unit 255 is turned off. In other words, when the operation switching unit 28 is in the first position, the operating mode of the crescent lock 2 is the first mode. Also, when the operation switching unit 28 is in the second position, the operation of the second acquisition unit 252 and the second control unit 255 is turned on. In other words, when the operation switching unit 28 is in the second position, the operating mode of the crescent lock 2 is the second mode. The crescent lock 2 is equipped with an operation switching unit 28, which allows the operation of the second acquisition unit 252 and the second control unit 255 to be switched on or off as needed, thereby reducing power consumption.

[0068] The processing unit 25 primarily consists of a computer system having, for example, one or more processors and one or more memories. In the Crescent Lock 2, the functions of the processing unit 25 are realized when one or more processors execute a program stored in memory. The program may be pre-stored in memory, provided via a telecommunication line such as the Internet, or provided on a non-temporary recording medium such as a memory card. For example, the processing unit 25 is located in the internal space of the lever base 31 of the lever part 3.

[0069] As shown in Figure 1, the processing unit 25 includes a first acquisition unit 251, a second acquisition unit 252, an authentication unit 253, a first control unit 254, and a second control unit 255.

[0070] The first acquisition unit 251 acquires biometric authentication information. In Embodiment 1, the first acquisition unit 251 acquires biometric authentication information from the biometric authentication sensor 22. When the operating mode of the control system 1 is registration mode, the first acquisition unit 251 stores the acquired biometric authentication information in the storage unit 24. Also, when the operating mode of the control system 1 is operation mode, the first acquisition unit 251 outputs the acquired biometric authentication information to the authentication unit 253.

[0071] The second acquisition unit 252 acquires second information, which is different from the biometric authentication information (first information). In Embodiment 1, the second acquisition unit 252 acquires second information from the release operation unit 6A (touch sensor).

[0072] The second acquisition unit 252 of Embodiment 1 acquires operation information as second information, which indicates the sequence of operations combining short-press and long-press operations on the touch sensor within a predetermined period (for example, within 20 seconds). Here, a long-press operation is a touch operation in which the time a person spends touching the touch sensor is longer than a short-press operation. More specifically, a short-press operation corresponds to a dot in Morse code, and a long-press operation corresponds to a dash in Morse code. For example, a dash is the length of three dots. In other words, a long-press operation is a touch operation in which the time a person spends touching the touch sensor is three times longer than a short-press operation. The second information of Embodiment 1 is Morse code information combining short-press operations (dots) and long-press operations (dashes).

[0073] Furthermore, the second acquisition unit 252 of Embodiment 1 acquires power information output from the monitoring unit 27 as second information.

[0074] The second acquisition unit 252 outputs the second information acquired when the operating mode of the control system 1 is in operation mode to the second control unit 255. The second acquisition unit 252 may also output the second information acquired when the operating mode of the control system 1 is in registration mode to the second control unit 255.

[0075] The authentication unit 253 performs authentication processing using the biometric authentication information acquired by the first acquisition unit 251. In Embodiment 1, the authentication unit 253 compares the fingerprint information acquired by the first acquisition unit 251 from the biometric authentication sensor 22 with the fingerprint information previously stored in the storage unit 24 and performs authentication processing.

[0076] The first control unit 254 controls the restriction mechanism 21 based on the result of the authentication process performed by the authentication unit 253. If the authentication process performed by the authentication unit 253 is successful, the first control unit 254 controls the restriction mechanism 21 to release the restriction. More specifically, if the authentication process is successful, the first control unit 254 controls the restriction mechanism 21 to make the pin 211 non-protruding. On the other hand, if the authentication process performed by the authentication unit 253 fails, the first control unit 254 does not release the restriction by the restriction mechanism 21.

[0077] The first control unit 254 controls the limiting mechanism 21 to restrict the operation of the lever unit 3 when a first predetermined period has elapsed since the limiting mechanism 21 was released. In other words, when the first control unit 254 releases the limit, the limit is released within the first predetermined period. The first predetermined period is, for example, 10 seconds. However, the first predetermined period can be set as appropriate.

[0078] The second control unit 255 controls the restriction mechanism 21 based on the second information acquired by the second acquisition unit 252. In Embodiment 1, the second control unit 255 controls the restriction mechanism 21 to release the restriction when the sequence of touch operations on the touch sensor (release operation unit 6A) indicated by the second information matches a pre-registered reference sequence. The reference sequence information is pre-stored in the storage unit 24. The reference sequence is Morse code information. According to the control system 1 of Embodiment 1, even a person other than one whose biometric authentication information has been pre-registered can release the restriction by the restriction mechanism 21 by performing a touch operation on the touch sensor (release operation unit 6A) according to the reference sequence. Because the control system 1 of Embodiment 1 releases the restriction of the restriction mechanism 21 using Morse code, the lever unit 3 can be operated more reliably while ensuring security and convenience. Furthermore, since the release operation unit 6A of Embodiment 1 only needs to detect touch operations on one area, the implementation area of ​​the release operation unit 6A can be reduced.

[0079] Furthermore, the second control unit 255 controls the limiting mechanism 21 to release the restriction when the remaining capacity of the battery 26, as indicated in the power information (second information), falls below a threshold capacity. According to the control system 1 of the embodiment, it is possible to suppress the situation in which the limiting mechanism 21 cannot operate and therefore the restriction cannot be released due to the remaining capacity of the battery 26 becoming low. This makes it possible to operate the lever unit 3 more reliably.

[0080] The second control unit 255 controls the limiting mechanism 21 to restrict the operation of the lever unit 3 at a time when a second predetermined period has elapsed from the time the limiting mechanism 21 is released. In other words, when the second control unit 255 releases the limit, the limit is released in a second predetermined period that is different from the first predetermined period. That is, according to the control system 1 of the embodiment 1, the period during which the limiting mechanism 21 is released differs depending on whether the limiting mechanism 21 is released based on first information or based on second information. This makes it possible to select a suitable release period depending on what information the limiting mechanism 21 was released based on.

[0081] In Embodiment 1, the second predetermined period is, for example, 10 minutes. In other words, in Embodiment 1, the period of restriction release is longer when the restriction of the restriction mechanism 21 is released based on the second information. This improves safety, for example, in the event of a disaster, when the restriction of the restriction mechanism 21 is released based on the second information, the restriction is released for a second predetermined period that is longer than the first predetermined period. However, the second predetermined period can be set as appropriate. In other words, the second predetermined period may be shorter than the first predetermined period.

[0082] Furthermore, in Embodiment 1, if the second control unit 255 releases the restriction of the limiting mechanism 21 based on the remaining capacity of the battery 26 being less than the threshold capacity, it does not restrict the operation of the lever unit 3 until the remaining capacity of the battery 26 becomes equal to or greater than the threshold capacity. In other words, even if a second predetermined period has elapsed since the release of the restriction by the limiting mechanism 21, the second control unit 255 in Embodiment 1 does not restrict the operation of the lever unit 3 if the remaining capacity of the battery 26 is less than the threshold capacity. This makes it possible to further suppress the situation in which the limiting mechanism 21 cannot operate and therefore the restriction cannot be released due to the remaining capacity of the battery 26 being low.

[0083] (3) Operation of the control system Next, the operation of the crescent lock 2 (or control system 1) will be described with reference to Figures 8 to 10. Note that the operation shown in Figures 8 to 10 is the operation when the crescent lock 2 is in operation mode. First, with reference to Figure 8, the operation in which the crescent lock 2 releases the restriction of the restriction mechanism 21 based on biometric authentication information (first information) will be described.

[0084] First, the crescent tablet 2 determines whether or not it has obtained biometric authentication information (first information) (step S1). If the crescent tablet 2 determines that it has not obtained biometric authentication information (step S1: No), it repeats the process in step S1. On the other hand, if the crescent tablet 2 determines that it has obtained biometric authentication information (step S1: Yes), it performs authentication processing using the obtained biometric authentication information (step S2).

[0085] Next, the crescent lock 2 determines whether or not authentication was successful (step S3). If authentication was unsuccessful, that is, if the acquired biometric information does not match the biometric information stored in the storage unit 24 (step S3: No), the crescent lock 2 repeats the process of step S1. On the other hand, if authentication was successful, that is, if the acquired biometric information matches the biometric information stored in the storage unit 24 (step S3: Yes), the crescent lock 2 releases the restriction by the restriction mechanism 21. In other words, if authentication is successful, the crescent lock 2 sets the pin 211 of the restriction mechanism 21 to a non-protruding state.

[0086] Next, the crescent lock 2 determines whether a first predetermined time has elapsed since the restriction by the restriction mechanism 21 was released (step S5). If the crescent lock 2 determines that the first predetermined time has not elapsed since the restriction by the restriction mechanism 21 was released (step S5: No), it repeats the process in step 5. On the other hand, if the crescent lock 2 determines that the first predetermined time has elapsed since the restriction by the restriction mechanism 21 was released (step S5: Yes), it controls the restriction mechanism 21 to restrict the operation of the lever part 3 (step S6). In other words, if the crescent lock 2 determines that the first predetermined time has elapsed since the restriction by the restriction mechanism 21 was released, it extends the pin 211 of the restriction mechanism 21. Then, the crescent lock 2 completes the series of processes shown in Figure 8.

[0087] Next, referring to Figure 9, the operation by which the crescent tablet 2 releases the restriction of the restriction mechanism 21 based on the second information will be described. The crescent tablet 2 determines what the current operating mode is (step S11). If the operating mode is the first mode and not the second mode (step S12: No), the process returns to step S11. On the other hand, if the operating mode is the second mode (step S12: Yes), the crescent tablet 2 determines whether or not it has acquired the second information (step S13). If the crescent tablet 2 has not acquired the second information (step S13: No), the process returns to step S11. On the other hand, if the crescent tablet 2 has acquired the second information (step S13: Yes), the crescent tablet 2 determines whether or not the second information satisfies predetermined conditions (step S14). In Embodiment 1, the crescent tablet 2 determines whether or not the order of touch operations indicated by the second information matches the reference order. If the second information does not satisfy predetermined conditions (step S14: No), the process returns to step S11. On the other hand, if the second information satisfies the predetermined conditions (step S14: Yes), the crescent tablet 2 releases the restriction by the restriction mechanism 21 (step S15).

[0088] Next, the crescent lock 2 determines whether a second predetermined time has elapsed since the restriction by the restriction mechanism 21 was released (step S16). If the crescent lock 2 determines that the second predetermined time has not elapsed since the restriction by the restriction mechanism 21 was released (step S16: No), it repeats the process in step S16. On the other hand, if the crescent lock 2 determines that the second predetermined time has elapsed since the restriction by the restriction mechanism 21 was released (step S16: Yes), it controls the restriction mechanism 21 to restrict the operation of the lever part 3 (step S17). In other words, if the crescent lock 2 determines that the second predetermined time has elapsed since the restriction by the restriction mechanism 21 was released, it extends the pin 211 of the restriction mechanism 21. Then, the crescent lock 2 completes the series of processes shown in Figure 9.

[0089] Next, referring to Figure 10, another operation in which the crescent tablet 2 releases the restriction of the restriction mechanism 21 based on the second information will be described. The crescent tablet 2 determines what the current operating mode is (step S21). If the operating mode is the first mode and not the second mode (step S22: No), the process returns to step S21. On the other hand, if the operating mode is the second mode (step S22: Yes), the crescent tablet 2 detects the remaining capacity of the battery 26 (step S23). Next, the crescent tablet 2 determines whether the remaining capacity of the battery 26 is equal to or greater than the threshold capacity (step S24). If the crescent tablet 2 determines that the remaining capacity of the battery 26 is equal to or greater than the threshold capacity (step S24: Yes), it terminates the series of processes shown in Figure 10. On the other hand, if the crescent tablet 2 determines that the remaining capacity of the battery 26 is less than the threshold capacity (step S24: No), it releases the restriction by the restriction mechanism 21 (step S25) and terminates the series of processes shown in Figure 10.

[0090] Note that the flowcharts shown in Figures 8 to 10 are merely examples, and the order of processing may be changed as appropriate, or processes may be added or deleted as appropriate.

[0091] (4) Variations The following are examples of modifications of Embodiment 1.

[0092] (4.1) Variation 1 As shown in Figure 11, the crescent lock 2 of Modified Example 1 is equipped with a release operation part 6B that functions as a release operation part 6. Although the crescent lock 2 of Modified Example 1 is equipped with a release operation part 6B instead of a release operation part 6A, it may also be equipped with a release operation part 6A.

[0093] The release operation unit 6B is a touchpad having multiple (four in the example in Figure 11) areas 61 that accept human touch operation. Each of the multiple areas 61 is labeled with a character. In the modified example 1, each of the multiple areas 61 is labeled with a number, but they may also be labeled with letters such as the alphabet. The release operation unit 6B is located on the front of the lever unit 3.

[0094] The multiple regions 61 include region 61A, region 61B, region 61C, and region 61D. Region 61A is labeled with the number "1". Region 61B is labeled with the number "2". Region 61C is labeled with the number "3". Region 61D is labeled with the number "4". The release operation unit 6B outputs operation information indicating the sequence of touch operations on the multiple regions 61 to the second acquisition unit 252.

[0095] The second acquisition unit 252 acquires operation information as second information, which indicates the sequence of touch operations on multiple areas 61 of the release operation unit 6B within a predetermined period. The second acquisition unit 252 outputs the operation information acquired as second information to the second control unit 255.

[0096] The second control unit 255 controls the restriction mechanism 21 to release the restriction when the order indicated by the second information matches a pre-registered reference order. For example, if the reference order is area 61A, area 61B, area 61C, and area 61D, the second control unit 255 controls the restriction mechanism 21 to release the restriction, provided that touch operations are performed in the order of area 61A, area 61B, area 61C, and area 61D within a predetermined period. As a result, a person who knows the string of characters for releasing the restriction of the restriction mechanism 21 (in the modified example 1, "1234") can release the restriction of the restriction mechanism 21 by performing touch operations in the order of area 61A, area 61B, area 61C, and area 61D within a predetermined period. For a person trying to release the restriction of the restriction mechanism 21, there is the advantage that it is easy to operate because they can release the restriction of the restriction mechanism 21 simply by operating the release operation unit 6B according to the string of characters (reference order). In addition, since the restriction of the restriction mechanism 21 can be released if one knows the string of characters corresponding to the reference order, there is the advantage that the method of releasing the restriction is easy to share.

[0097] (4.2) Modification 2 As shown in Figure 12, the crescent lock 2 of Modified Example 2 is equipped with a release operation part 6C that functions as a release operation part 6. Although the crescent lock 2 of Modified Example 2 is equipped with a release operation part 6C instead of a release operation part 6A, it may also be equipped with a release operation part 6A.

[0098] The release operation unit 6C is a touchpad having multiple (nine in the example in Figure 12) areas 61 that accept human touch operations (or drag operations). In the modified example 2, each of the multiple areas 61 has a square-shaped point in its center. The release operation unit 6C is located on the front of the lever unit 3.

[0099] The multiple regions 61 include regions 61E, 61F, 61G, 61H, 61I, 61J, 61K, 61L, and 61M. Regions 61E, 61F, 61G, 61H, 61I, 61J, 61K, 61L, and 61M are arranged in a 3x3 matrix. In the upper row of the release operation unit 6C, regions 61E, 61F, and 61G are arranged from left to right. In the middle row of the release operation unit 6C, regions 61H, 61I, and 61J are arranged from left to right. In the lower row of the release operation unit 6C, regions 61K, 61L, and 61M are arranged from left to right. The release operation unit 6C outputs operation information to the second acquisition unit 252 indicating the order of drag operations on at least two of the multiple regions 61.

[0100] The second acquisition unit 252 acquires operation information as second information, which indicates the sequence of drag operations on at least two of the multiple regions 61 within a predetermined period. The second acquisition unit 252 outputs the operation information acquired as second information to the second control unit 255.

[0101] The second control unit 255 controls the limiting mechanism 21 to release the restriction when the order indicated by the second information matches a pre-registered reference order. For example, if the reference order is in the order of region 61E, region 61F, region 61G, region 61I, region 61K, region 61L, and region 61M, the second control unit 255 controls the limiting mechanism 21 to release the restriction, provided that the drag operation is performed in the order of region 61E, region 61F, region 61G, region 61I, region 61K, region 61L, and region 61M within a predetermined period. Note that by writing the letter "Z" to the release operation unit 6C, the drag operation can be performed in the order of region 61E, region 61F, region 61G, region 61I, region 61K, region 61L, and region 61M. A person who knows the standard sequence for releasing the restriction of the restriction mechanism 21 can release the restriction of the restriction mechanism 21 by dragging through areas 61E, 61F, 61G, 61I, 61K, 61L, and 61M in that order within a predetermined period. For a person trying to release the restriction of the restriction mechanism 21, there is the advantage that it is easy to operate, as the restriction of the restriction mechanism 21 can be released simply by operating the release operation unit 6C, for example, as if writing characters. Furthermore, since the release operation unit 6C of the modified example 2 has nine areas 61, complex patterns (standard sequences) can be registered in advance, thereby improving security.

[0102] (4.3) Other variations Functions equivalent to the control system 1 according to the above embodiment may be embodied in a control method, a (computer) program, or a non-temporary recording medium on which the program is recorded. One control method according to one embodiment is a method executed in a control system 1 equipped with a crescent lock 2. The crescent lock 2 has a restriction mechanism 21. The restriction mechanism 21 restricts the operation of the lever portion 3 of the crescent lock 2, making the lever portion 3 inoperable. The control method includes a first acquisition step, a second acquisition step, an authentication step, a first control step, and a second control step. In the first acquisition step, first information, which is biometric authentication information, is acquired. In the second acquisition step, second information, which is information different from biometric authentication information, is acquired. In the authentication step, authentication processing is performed using the first information acquired in the first acquisition step. In the first control step, if authentication is successful in the authentication step, the restriction mechanism 21 is controlled to release the restriction. In the second control step, the restriction mechanism 21 is controlled to release the restriction based on the second information acquired in the second acquisition step. A program according to one embodiment is a program that causes one or more processors to execute the above-described control method.

[0103] The entity executing the control system 1 or control method in this disclosure includes a computer system. The computer system mainly consists of a processor and memory as hardware. The processor executes a program recorded in the computer system's memory to realize the function of the entity executing the control system 1 or control method in this disclosure. The program may be pre-recorded in the computer system's memory, provided via a telecommunications line, or provided on a non-temporary recording medium such as a memory card, optical disk, or hard disk drive that is readable by the computer system. The processor of the computer system consists of one or more electronic circuits including semiconductor integrated circuits (ICs) or large-scale integrated circuits (LSIs). The integrated circuits referred to here, such as ICs or LSIs, are named differently depending on the degree of integration and include integrated circuits called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Furthermore, FPGAs (Field-Programmable Gate Arrays) that are programmed after the manufacture of the LSI, or logic devices that allow for the reconfiguration of junction relationships or circuit compartments within the LSI, can also be used as processors. Multiple electronic circuits may be integrated onto a single chip or distributed across multiple chips. Multiple chips may be integrated onto a single device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller also consists of one or more electronic circuits, including semiconductor integrated circuits or large-scale integrated circuits.

[0104] Furthermore, it is not essential for the control system 1 to have multiple functions integrated into a single housing (e.g., the crescent lock 2), and the components of the control system 1 may be distributed across multiple housings. In addition, at least some of the functions of the control system 1, for example, some of the functions of the crescent lock 2, may be implemented by the cloud (cloud computing), etc.

[0105] Embodiment 1 illustrates a case where the pin 211 of the limiting mechanism 21 is provided on the lever portion 3, and the hole 212 and groove 213 of the limiting mechanism 21 are provided on the base portion 4. However, the pin 211 of the limiting mechanism may be provided on the base portion 4, and the hole 212 and groove 213 of the limiting mechanism 21 may be provided on the lever portion 3. In other words, the limiting mechanism 21 only needs to have a pin 211 provided on one of the lever portion 3 and the base portion 4 and configured to protrude from one to the other, and a hole 212 provided on the other of the lever portion 3 and the base portion 4 into which the protruding pin 211 is inserted. Furthermore, if the pin 211 is provided on the base portion 4 and the hole 212 is provided on the lever portion 3, the groove 213 may be provided on the lever portion.

[0106] Embodiment 1 illustrates a case where the biometric authentication sensor 22 and the unlock operation unit 6A are integrated into a single unit. However, the biometric authentication sensor 22 and the unlock operation unit 6A may be separate components.

[0107] Embodiment 1 illustrates a case where the biometric authentication sensor 22 is a fingerprint authentication sensor. However, the biometric authentication sensor 22 may also be a vein authentication sensor that acquires vein information as biometric authentication information from a person. By using a vein authentication sensor as the biometric authentication sensor 22, the reliability of the authentication process can be improved. The biometric authentication sensor 22 may also be an iris authentication sensor or a voiceprint authentication sensor, etc. Furthermore, the biometric authentication sensor 22 may be a camera, and authentication processing such as facial recognition may be performed.

[0108] Embodiment 1 illustrates a case where the first acquisition unit 251 acquires biometric authentication information from the biometric authentication sensor 22. However, the first acquisition unit 251 may also acquire biometric authentication information from other information devices, such as a smartphone equipped with a biometric authentication sensor.

[0109] The first acquisition unit 251 and the second acquisition unit 252 may be configured as a single acquisition unit. Also, the first control unit 254 and the second control unit 255 may be configured as a single control unit.

[0110] (Embodiment 2) (1) Composition As shown in Figure 13, the control system 1 of Embodiment 2 differs from the control system 1 of Embodiment 1 in that it includes a crescent lock 2 and an information device 8 (external device).

[0111] The information device 8 in Embodiment 2 is a smartphone. However, the information device 8 may be a PC (personal computer) or a tablet terminal, etc. The information device 8 in Embodiment 2 has an operating unit that accepts human operation. Furthermore, the information device 8 in Embodiment 2 is configured to communicate with other devices such as the crescent lock 2. As used in this disclosure, "communicable" means that signals can be sent and received directly or indirectly via a network or relay, etc., by an appropriate communication method such as wired communication or wireless communication.

[0112] In the second embodiment, the information device 8 transmits information to the crescent lock 2 to release the restriction of the restriction mechanism 21 when an operation is performed on the operating unit to release the restriction of the restriction mechanism 21.

[0113] The crescent lock 2 further includes a communication unit 29 compared to the crescent lock 2 of Embodiment 1. The communication unit 29 includes an interface that can communicate with the information device 8. In other words, the communication unit 29 is configured to communicate with an external device separate from the crescent lock 2.

[0114] The communication unit 29 communicates with the information device 8 and receives information from the information device 8 to release the restrictions of the restriction mechanism 21.

[0115] The second acquisition unit 252 of Embodiment 2 acquires, as the second information, information for releasing the restriction of the restriction mechanism 21 that the communication unit 29 has received from the information device 8.

[0116] In Embodiment 2, the second control unit 255 controls the restriction mechanism 21 to release the restriction based on the second information acquired by the second acquisition unit 252 via the communication unit 29. According to the control system 1 of Embodiment 2, a person who wishes to release the restriction of the restriction mechanism 21 can release the restriction of the restriction mechanism 21 by, for example, performing an operation to release the restriction of the restriction mechanism 21 on an external device (information device 8) separate from the crescent lock 2. This makes it possible to release the restriction on the operation of the lever unit 3 even for a person whose biometric authentication information has not been registered in advance, and makes it possible to operate the lever unit 3 more reliably. In addition, since an information device 8 separate from the crescent lock 2 is used, the level of security can be improved.

[0117] (2) Variant The following are examples of modifications of Embodiment 2.

[0118] (2.1) Variation 1 In variation 1, the crescent lock 2 and the information device 8 (external device) are located in the same house.

[0119] The information device 8 in Modification 1 has a mechanical operating part for releasing the restriction by the restriction mechanism 21. More specifically, the information device 8 has a push button for releasing the restriction by the restriction mechanism 21. The information device 8 in Modification 1 is installed, for example, in a room where a crescent lock 2 is installed, out of the reach of children. When the push button is pressed by a person, the information device 8 transmits information to the crescent lock 2 for releasing the restriction by the restriction mechanism 21.

[0120] The second control unit 255 controls the restriction mechanism 21 to release the restriction when the second acquisition unit 252 acquires second information indicating that an operation to release the restriction has been performed on the operation unit of the information device 8. In other words, the second control unit 255 controls the restriction mechanism 21 to release the restriction when the push button of the information device 8 is pressed by a person.

[0121] According to the control system 1 of Modified Example 1, it is possible to release the restriction on the operation of the lever 3 even for individuals whose biometric authentication information has not been registered in advance, making the lever 3 more reliable to operate. Furthermore, in the control system 1 of Modified Example 1, the restriction on the restriction mechanism 21 is released simply by pressing a button, making the lever 3 more reliable to operate in the event of a disaster or other emergency.

[0122] (2.2) Modification example 2 In variation 2, the crescent lock 2 and the information device 8 (external device) are located in the same house.

[0123] In Modification 2, the information device 8 is a home controller installed in the house. In Modification 2, the information device 8 is a controller for a HEMS (Home Energy Management System). The information device 8 is a controller for stabilizing the power supply within the house where it is installed. However, the information device 8 may also be an energy monitor for the HEMS, an intercom master unit, or an AI speaker, etc.

[0124] The information device 8 in Modified Example 2 has an operating section that accepts human input. Furthermore, the information device 8 in Modified Example 2 is configured to communicate with other devices such as the crescent lock 2. When an operation is performed on the operating section of the information device 8 in Modified Example 2 to release the restriction of the restriction mechanism 21, the information device 8 transmits information to the crescent lock 2 to release the restriction of the restriction mechanism 21.

[0125] When the second acquisition unit 252 acquires second information indicating that an operation to release the restriction has been performed on the operation unit of the information device 8, the second control unit 255 controls the restriction mechanism 21 to release the restriction.

[0126] According to the control system 1 of modified example 2, it is possible to release the restrictions on the operation of the lever 3 even for individuals whose biometric authentication information has not been registered in advance, making the lever 3 more reliable to operate. Furthermore, since the information device 8 of modified example 2 is a home controller, it is possible to release the restrictions of the restriction mechanism 21 using existing systems installed in the house.

[0127] (2.3) Modification 3 In variation 3, the crescent lock 2 and the information device 8 (external device) are located in the same house.

[0128] The information device 8 in Modification 3 is a device included in an alarm system that detects the occurrence of a disaster and issues an alarm. The information device 8 in Modification 3 is a detector that detects the occurrence of a disaster. However, the information device 8 may also be a repeater or receiver configured to communicate with the detector. The information device 8, which is a detector, has a sensor that detects a specific physical quantity related to the disaster. The sensor may be, for example, a heat sensor, a smoke sensor, an infrared sensor, an ultraviolet sensor, etc., and the specific physical quantity detected by the sensor may be heat (temperature), smoke (particulate matter) concentration, ultraviolet intensity, infrared intensity, etc. That is, the information device 8 may be a so-called heat detector that has a heat sensor and detects heat (temperature rise) due to a fire. The information device 8 may also be a so-called smoke detector that has a smoke sensor and detects smoke or minute combustion products due to a fire. The information device 8 may also be a so-called flame detector that has an infrared sensor or an ultraviolet sensor and detects flames due to a fire. The information device 8 may also be a so-called composite detector that has two or more types of sensors, such as a heat sensor and a smoke sensor, that each detect a physical quantity. Furthermore, the information device 8 may also have sensors for detecting abnormalities in facilities other than fire, such as gas leaks, earthquakes, and flooding.

[0129] In Modification 3, the information device 8 is configured to communicate with the crescent lock 2. When the information device 8 in Modification 3 detects the occurrence of a disaster, it transmits information to the crescent lock 2 to release the restriction of the restriction mechanism 21.

[0130] When the second information acquisition unit 252 acquires second information indicating that a disaster has occurred, the second control unit 255 controls the restriction mechanism 21 to release the restriction.

[0131] According to the control system 1 of modified example 3, the restriction mechanism 21 is automatically released when a disaster occurs, making it possible to operate the lever part 3 more reliably.

[0132] (2.4) Modification 4 As shown in Figure 14, the communication unit 29 in Modification 4 is a card reader. The card reader is configured to communicate with a contactless authentication terminal that stores identification information. The card reader is configured to perform near-field wireless communication with the authentication terminal held over it and to read the identification information from the authentication terminal. In Modification 4, the authentication terminal is an IC (Integrated Circuit) card. Near-field wireless communication is, for example, NFC (Near Field Communication). The card reader may also be configured to perform near-field wireless communication with a mobile terminal such as a smartphone held over it and to read the identification information from the mobile terminal. The card reader outputs the read identification information to the second acquisition unit 252.

[0133] The second acquisition unit 252 acquires the identification information of the authentication terminal (IC card) received by the communication unit 29 (card reader) as second information.

[0134] The second control unit 255 controls the restriction mechanism 21 to release the restriction when the identification information acquired by the second acquisition unit 252 matches a pre-registered reference identification information.

[0135] According to the control system 1 of modified example 4, even for individuals whose biometric authentication information has not been registered in advance, it is possible to remove the restrictions on the operation of the lever unit 3 by using an authentication terminal in which identification information has been registered in advance, thereby enabling the lever unit 3 to operate more reliably.

[0136] (Embodiment 3) (1) Composition As shown in Figure 15, the crescent lock 2 of Embodiment 3 further includes a shape detection unit 9 compared to the crescent lock 2 of Embodiment 1.

[0137] The shape detection unit 9 detects the shape of the object X1 (see Figure 16) used as a key. As shown in Figure 17, the object X1 of Embodiment 3 has a plate-shaped base portion X10 and a plurality of recesses X11 formed on the main surface of the base portion X10. The object X1 of Embodiment 3 is a so-called dimple key.

[0138] As shown in Figure 16, the shape detection unit 9 of Embodiment 3 is provided on the lever unit 3. The shape detection unit 9 has a recess 91 into which the base unit X10 of object X1 can be inserted, and a shape detection mechanism 92.

[0139] The shape detection mechanism 92 includes, for example, a plurality of pins and a click device that displaces the plurality of pins. The plurality of pins are in a first position when nothing is inserted into the recess 91. The plurality of pins are displaced to a second position when the base portion X10 of an object X1 is inserted into the recess 91. The second position differs depending on the shape of the object inserted into the recess 91. More specifically, the second position of each of the plurality of pins differs depending on the shape of the base portion X10 of the object X1 inserted into the recess 91, the arrangement of the plurality of recesses X11, the depth of the recesses X11, etc.

[0140] For example, the shape detection unit 9 of Embodiment 3 outputs the amount of displacement of the multiple pins from the first position to the second position when the base portion X10 of object X1 is inserted into the recess 91 to the second acquisition unit 252 as shape information of object X1.

[0141] The second acquisition unit 252 acquires the shape information detected by the shape detection unit 9 as second information.

[0142] The second control unit 255 controls the limiting mechanism 21 to release the restriction when the shape information acquired by the second acquisition unit 252 matches pre-registered reference shape information. For example, in Embodiment 3, the reference shape information is information on the displacement amounts of multiple pins.

[0143] According to the control system 1 of Embodiment 3, even for individuals whose biometric authentication information has not been registered in advance, the restriction on the operation of the lever 3 can be released, making the lever 3 more reliable to operate. Furthermore, by making the shape of the object X1 used as a key, for example, a dimple key shape, the level of security can be improved.

[0144] (2) Variant Object X1 may be a key other than a dimple key. As shown in Figure 18, object X1 may be a comb-shaped key. The shape of the modified object X1 differs from the shape of object X1 in Embodiment 3. The modified object X1 has a plate-shaped base portion X20 and a plurality of comb teeth X21 protruding from the tip of the base portion X20.
