[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, identical or substantially identical configurations and elements will be designated by the same reference numerals and will not be described repeatedly.

[0010] FIG. 1 shows an example of a door scope 10 installed on a door 101. The door 101 is installed in, for example, an apartment or condominium, and separates the interior from the exterior. The arrow IS shown in the figure indicates the interior side, and the arrow OS shown in the figure indicates the exterior side. Hereinafter, the interior side will be referred to as the interior side IS, and the exterior side will be referred to as the exterior side OS.

[0011] The door 101 has two support portions 102 on one side. A handle 103 is provided near the opposite side of the support portion 102. For example, when a resident presses the handle 103, the door 101 opens in the direction of the arrow shown in the figure. A lens portion (described later) is provided at the top of the door 101, for example, at a position within the resident's line of sight. The resident can view the outdoor side OS from the indoor side IS through the lens portion. In this embodiment, a peephole 10 is installed on the door 101 so as to cover the lens portion.

[0012] Fig. 2 is a diagram showing an example of the front of the patio door 10. Fig. 3 is a diagram showing an example of the side of the patio door 10. Fig. 4 is a diagram showing an example of the back of the patio door 10. The appearance of the patio door 10 as seen from the indoor side IS is the front, and the appearance of the patio door 10 as seen from the outdoor side OS (door 101 side) looking through the door 101 is the back.

[0013] As shown in FIGS. 2 and 3, the peephole 10 includes a housing (described later), a first hole 21 on a first surface 10A of the housing, and a second hole 22 on a second surface 10B opposite the first surface 10A. The peephole 10 is mounted on the door 101 so that the first and second holes 21 and 22 are positioned in the lens 101A of the door 101, with the first surface 10A facing the interior side IS and the second surface 10B facing the exterior side OS (the door 101 side). This allows an occupant on the interior side IS to view the exterior side OS through the lens 101A, first hole 21, and second hole 22 of the door 101. For example, the occupant can view a visitor standing outside the door 101.

[0014] The first hole 21 and the second hole 22 are provided in the center of the patio door 10. A nut 11 is provided on the top of the patio door 10. The nut 11 secures the cover 13 and the bottom 14 together. The cover 13 and the bottom 14 form the housing of the patio door 10. A proximity sensor 12 is provided on the underside of the patio door 10. The proximity sensor 12 detects objects without contact. In this embodiment, the proximity sensor 12 detects an object as an occupant approaching the door 101 from the indoor side IS.

[0015] As shown in Figures 3 and 4, a rectangular recess 10C is provided below the center of the bottom 14, extending in the lateral direction of the door 101. The recess 10C includes a portion of the second hole 22. A slider 32 is provided in the recess 10C. The slider 32 is configured to be, for example, rectangular so as to fit along the recess 10C. The slider 32 is configured so that its position can be adjusted. The slider 32 includes a light sensor 34. The light sensor 34 detects light from the outdoor side OS via the lens 101A.

[0016] The optical sensor 34 is disposed on the slider portion 32 so that a portion of the optical sensor 34 overlaps the first hole 21 and the second hole 22. A portion of the slider portion 32 is connected to the dial 31 via a connecting member 33. A portion of the dial 31 protrudes from the side of the housing of the peephole 10. This allows the resident to turn the dial 31 even after the peephole 10 has been installed on the door 101. For example, when the dial 31 is turned as shown by the arrow in the figure, the slider portion 32 is pulled by the connecting member 33 in accordance with the amount of rotation, causing it to move in the direction of the arrow in the figure.

[0017] Fig. 5 is a diagram showing an example of the internal structure of the door scope 10. Fig. 5 schematically shows the door scope 10 with the cover 13 removed.

[0018] As shown in FIG. 5, a hole 41 for inserting a nut 11 is provided on the upper side of the bottom 14. Magnets 42 and 43 are also attached to the upper side of the bottom 14. The peephole 10 is fixed to the door 101 by the magnetic forces of these two magnets 42 and 43. A blade opening and closing device 50 is attached to the center of the bottom 14 by a fixing member 44. A circuit board 45 is attached to the lower side of the blade opening and closing device 50 by fixing members 45A to 45D. A control unit 46 and a button battery 47 are provided on the circuit board 45. The control unit 46 and other components operate using power supplied from the button battery 47.

[0019] FIG. 6 is a diagram showing an example of the main control configuration of the door viewer 10 including the blade opening and closing device 50. As shown in FIG. 6, the door viewer 10 includes a control unit 46, a proximity sensor 12, an optical sensor 34, and a blade opening and closing device 50. The blade opening and closing device 50 includes an actuator 51, which serves as a threat processing unit and a drive unit, and blades 52. The actuator 51 is electrically connected to the control unit 46. The proximity sensor 12 and the optical sensor 34 are connected to the control unit 46. The blades 52 are connected to the actuator 51 so as to be operated by electromagnetic driving of the actuator 51.

[0020] The control unit 46 receives outputs from the proximity sensor 12 and the optical sensor 34, and applies current to a coil (described later) of the actuator 51 based on the received outputs. The actuator 51 operates the position of the blade 52 according to the amount of current supplied based on instructions from the control unit 46. For example, based on the control of the control unit 46, the actuator 51 operates the blade 52 to a first position where the blade 52 blocks the gap between the first hole 21 and the second hole 22, or to a second position where the blade 52 does not block the gap between the first hole 21 and the second hole 22. Furthermore, the actuator 51 vibrates the blade 52 while maintaining the gap between the first hole 21 and the second hole 22 blocked.

[0021] Next, a mechanism for operating the blades 52 of the blade opening / closing device 50 will be described. 7A and 7B are plan views schematically showing an example of the operation of actuator 51. As shown in FIGS. 7A and 7B, actuator 51 includes yoke 61, arm portions 61A and 61B, coil 63, rotor magnet 64, lever member 65, and engagement portion 66. FIGS. 8A and 8B are plan views schematically showing an example of the position of blade 52. FIGS. 8A and 8B show the position of blade 52 above base member 70 included in blade opening and closing device 50. Note that blade opening and closing device 50 also includes other members, but descriptions of these will be omitted in this embodiment.

[0022] In the actuator 51 of this embodiment, when current is passed through the coil 63 of the actuator 51 through wiring (not shown) on the substrate 45, the arm portions 61A and 61B of the yoke 61 are magnetized to opposite magnetic poles, and the rotor magnet 64 rotates due to the attraction caused by the magnetic force of the arm portions 61A and 61B.

[0023] For example, when current is applied in one direction to the coil 63 of the actuator 51, the arms 61A and 61B of the yoke 61 are magnetized as shown in FIG. 7A. The magnetic poles of the rotor magnet 64 are attracted to the opposite magnetic poles of the arms 61A and 61B of the yoke 61, causing the rotor magnet 64 to rotate clockwise around the axis 71. At this time, the engaging portion 66 of the lever member 65 engages with the cam groove 53 of the blade 52, causing the blade 52 to move in the −X direction and assume the second position shown in FIG. 8A. In this second position, the blade 52 does not block the first hole 21 and the second hole 22, leaving the first hole 21 and the second hole 22 open. In other words, light from outside reaches the indoor side IS through the lens 101A of the door 101 and the peephole 10, allowing the occupant to view the outdoor side OS.

[0024] When current is applied to the coil 63 of the actuator 51 in the opposite direction to that shown in FIG. 7A, the arms 61A and 61B of the yoke 61 are magnetized as shown in FIG. 7B. The magnetic poles of the rotor magnet 64 are attracted to the opposite magnetic poles of the arms 61A and 61B of the yoke 61, causing the rotor magnet 64 to rotate counterclockwise around the axis 71. At this time, the engaging portion 66 of the lever member 65 engages with the cam groove 53 of the blade 52, causing the blade 52 to move in the +X direction to the first position shown in FIG. 8B. In this first position, the blade 52 blocks the gap between the first hole 21 and the second hole 22. This means that light from outside cannot reach the indoor side IS through the lens 101A of the door 101 and the peephole 10, preventing the occupant from viewing the outdoor side OS. Furthermore, even if a visitor to the outside OS takes measures to change the light path using a monocular lens or the like, they will not be able to see the inside IS.

[0025] In this way, the actuator 51 is capable of rotating the rotor magnet 64 between two positions by receiving power from the substrate 45, and moving the blades 52 between the first and second positions via the engagement portion 66 of the lever member 65.

[0026] In this embodiment, the shape of the yoke 61 is adjusted so that the rotor magnet 64 is attracted to the yoke 61 by the magnetic force of the rotor magnet 64 when no current is supplied to the coil 63 of the actuator 51. Specifically, in the state shown in Fig. 7A, even when the supply of current to the coil 63 of the actuator 51 is stopped, the rotor magnet 64 can maintain its position by the magnetic force it exerts on the yoke 61. Similarly, in the state shown in Fig. 7B, even when the supply of current to the coil 63 of the actuator 51 is stopped, the rotor magnet 64 can maintain its position by the magnetic force it exerts on the yoke 61.

[0027] By adjusting the shape of the yoke 61 in this manner, it is possible to prevent the blades 52 from unintentionally moving from the first position or the second position or from stopping between the first and second positions when no current is supplied to the coil 63 of the actuator 51. The shape of the yoke 61 may also be adjusted so that the rotor magnet 64 is held at only one of the first and second positions. In particular, if the rotor magnet 64 can be held at the first position, the first hole 21 and the second hole 22 will be blocked by the blades 52 even when no current is supplied to the coil 63 of the actuator 51, thereby more reliably preventing the possibility of the indoor side IS being photographed.

[0028] Next, a description will be given of energization control when opening and closing blades 52. Fig. 9 is a diagram showing an example of energization control to coil 63 of actuator 51. As shown in Figure 9, when there is no current flowing, the blades 52 are located in the second position (OPEN). When current flowing is started from this state, the blades 52 move to the first position (CLOSE). When the current flow is reversed, the blades 52 move to the second position (OPEN).

[0029] Next, a description will be given of energization control when blade 52 vibrates while blocking the gap between first hole 21 and second hole 22. Fig. 10 is a diagram showing an example of energization control to coil 63 of actuator 51 during vibration.

[0030] 10, when the blades 52 are in the first position (CLOSE), the power supply is controlled so that the blades 52 vibrate in small increments so that they are not in the second position (OPEN). Operating the blades 52 in this manner generates abnormal noise (mechanical operating noise). In this embodiment, when the optical sensor 34 receives light, the vibration operation of the blades 52 is executed.

[0031] 11 is a diagram illustrating the process of adjusting the position of the optical sensor 34 when installing the peephole 10 on the door 101. The position of the slider 32 is adjusted from the initial position where the optical sensor 34 detects light when the peephole 10 is installed to an adjusted position where it no longer detects light.

[0032] More specifically, as shown in FIG. 4, in the default state, the optical sensor 34 is positioned to receive light from the outdoor side OS through the lens 101A of the door 101. Therefore, when the peephole 10 is installed on the door 101 and operation is started, the control unit 46 receives an output from the optical sensor 34 indicating that light is being received. In this case, the control unit 46 executes the power supply control shown in FIG. 10. This causes the blades 52 to vibrate, generating abnormal noise.

[0033] In this state, for example, if a resident turns the dial 31 to move the slider 32 in the direction of the arrow, the position of the optical sensor 34 also moves in the direction of the arrow. This gradually reduces the amount of light received by the optical sensor 34. Then, as shown in FIG. 11 , when the light receiving area of ​​the optical sensor 34 no longer overlaps with the light flux area AR1 of diameter D1, the control unit 46 receives an output from the optical sensor 34 indicating that light is no longer being received. In this case, the control unit 46 stops the vibration of the blades 52. This stops the abnormal noise generated by the blade opening / closing device 50. The resident stops turning the dial 31 when the abnormal noise no longer occurs. In this way, the position of the optical sensor 34 is adjusted. In this way, an installer, such as a resident, can fine-tune the position of the slider 32 on which the optical sensor 34 is mounted to position the slider 32 at the optimal position for the optical sensor 34 to detect light.

[0034] Next, a description will be given of the operation of the blades 52 of the blade opening / closing device 50 of the peephole 10 installed on the door 101. Fig. 12 is a flowchart showing an example of the processing when an occupant approaches the peephole 10 from the room side IS.

[0035] 12, in step ST101, the control unit 46 controls the energization to position the blades 52 at the first position. In the first position, the blades 52 block the space between the first hole 21 and the second hole 22. Therefore, the indoor side IS cannot be photographed from the outdoor side OS, but the outdoor side OS cannot be seen from the indoor side IS either.

[0036] Next, in step ST102, control unit 46 determines whether proximity sensor 12 has detected an object (first object). In this embodiment, the object is a resident. Control unit 46 receives an output from proximity sensor 12 indicating whether an object has been detected. If control unit 46 receives an output indicating that an object has been detected, control unit 46 determines that an object, i.e., a resident, has been detected. If the determination in step ST102 is NO, the process returns to step ST101. That is, the state in which blades 52 are located in the first position continues.

[0037] If the determination in step ST102 is YES, in step ST103, the control unit 46 controls the energization to position the blades 52 at the second position. In the second position, the blades 52 are not positioned between the first hole 21 and the second hole 22. This makes it possible for the outdoor side OS to be seen from the indoor side IS. This allows the occupant to visually recognize the outdoor side OS.

[0038] Next, in step ST104, control unit 46 determines whether or not proximity sensor 12 has detected an object. If the determination in step ST104 is YES, the process returns to step ST103. In other words, if an occupant has been detected, blades 52 continue to be positioned in the second position.

[0039] On the other hand, if the determination in step ST104 is NO, the process returns to step ST101. As a result, the control unit 46 performs power supply control to move the blades 52 from the second position to the first position. In other words, when an occupant is no longer detected, the blades 52 return to the state of being located at the first position. As a result, the indoor side IS will no longer be photographed from the outdoor side OS.

[0040] Thus, when no resident is approaching the peephole 10, the blades 52 are in the first position, preventing the indoor side IS from being seen from the outdoor side OS. On the other hand, when a resident approaches the peephole 10, the blades 52 are in the second position, allowing the outdoor side OS to be seen from the indoor side IS. This prevents the interior of the room from being photographed from outside, and allows the resident to see outside without any effort. For example, even if a resident is unable to use their hands to view the outside, the resident can still peek outside. Therefore, the peephole 10 equipped with the blade opening and closing device 50 can improve accessibility while protecting privacy.

[0041] Next, we will explain the operation of the blades of the blade opening and closing device 50 when a visitor, intending to invade privacy, attempts to photograph the indoor side IS from the outdoor side OS. By overlapping the monocular lens with the lens unit 101A of the door 101, the optical path of the lens unit 101A is changed, making the indoor side IS visible from the outdoor side OS. Using this principle, a visitor may photograph the indoor space by photographing the monocular lens 80 with a smartphone 81 (see FIG. 15 ), thereby invading privacy. In this embodiment, when the resident is not near the peephole 10, the blades 52 are positioned in the first position, preventing the indoor space from being photographed from outside. Furthermore, the peephole 10 can implement the following security measures against visitors.

[0042] FIG. 13 is a flowchart showing an example of a process executed when a visitor from outside tries to invade privacy.

[0043] 13, in step ST201, the control unit 46 determines whether or not the optical sensor 34 has detected light. The optical sensor 34 has been adjusted to a position where it does not detect light by the operation described in FIG. 11, but it detects light in the following cases.

[0044] 14 is a diagram schematically illustrating an example of a light beam incident from outside the room through the lens unit 101A. In this case, the light beam falls within a light beam area AR1 having a diameter D1 (see, for example, FIG. 11). When the light beam is within the light beam area AR1, the optical sensor 34 does not receive the light.

[0045] FIG. 15 is a diagram schematically illustrating an example of a light beam incident from outside the room through the lens unit 101A when the monocular lens 80 is placed on the lens unit 101A. In this case, the light path is changed, and the diameter of the light beam becomes diameter D2, which is larger than diameter D1. FIG. 16 is a diagram illustrating an example of a light beam region AR2 changed by the change of the light path. Compared to the example in FIG. 11, the light beam region becomes light beam region AR2 from light beam region AR1, and the light beam region is expanded. Therefore, the light sensor 34, which did not receive light in FIG. 11, receives light in FIG. 16. In this way, the light sensor 34 receives light. As shown in FIG. 16, the light sensor 34 is, in other words, a sensor that non-contactly detects whether the monocular lens 80 (second object) is approaching from outside the room.

[0046] If the determination in step ST201 is NO, the process returns to step ST201. As a result, blades 52 remain in the first position. If the determination in step ST201 is YES, control unit 46 vibrates blades 52 in step ST202. That is, control unit 46 executes the vibration control described above with reference to FIG. 10. More specifically, when optical sensor 34 detects light at the adjusted position to which the position of optical sensor 34 has been adjusted, in other words, when it detects monocular lens 80, actuator 51 vibrates blades 52 while maintaining the gap between first hole 21 and second hole 22 blocked. This causes abnormal noise to be generated from blade opening / closing device 50. This may discourage visitors from taking pictures of the interior of the room.

[0047] Next, in step ST203, control unit 46 determines whether or not optical sensor 34 detects light. If the determination in step ST203 is YES, the process returns to step ST202. That is, vibration control of blades 52 continues, and the state in which abnormal noise is generated from blade opening / closing device 50 continues.

[0048] If the determination in step ST203 is NO, control unit 46 moves blade 52 to the first position in step ST204. Here, a case in which the determination is NO occurs, for example, when monocular lens 80 that was placed on lens unit 101A is removed. At this time, the light flux area returns from light flux area AR2 shown in FIG. 16 to light flux area AR1 shown in FIG. 11, and optical sensor 34 no longer detects light. Thereafter, the process returns to step ST201. That is, after vibration control of blade 52 is stopped, blade 52 returns to the first position.

[0049] In this way, if a visitor tries to take a picture of the room with smartphone 81 using monocular lens 80, blade opening / closing device 50 can intimidate the visitor by emitting an abnormal noise. When an abnormal noise is generated, blades 52 vibrate, but because blades 52 vibrate while blocking the space between first hole portion 21 and second hole portion 22, it is possible to prevent the room from being photographed even while emitting the abnormal noise. In other words, it is possible to intimidate visitors who engage in privacy-invading behavior while protecting privacy.

[0050] In the present embodiment, the blade opening / closing device 50 operates the blades 52 to generate an abnormal noise to deter intruders. However, the deterrent method is not limited to this. For example, the peephole 10 may include a light-emitting device (e.g., a light-emitting diode) that can emit light toward the outdoor side OS via the optical path of the lens unit 101A, and the light-emitting device may emit light when the optical sensor 34 detects light. Alternatively, the peephole 10 may be provided with a communication device or the like, and an outdoor device located outside the room may be activated when the optical sensor 34 detects light. Examples of outdoor devices include a lighting device and an intercom. When the optical sensor 34 detects light, the lighting device may repeatedly turn on and off, or the intercom may emit a sound.

[0051] In the above embodiment, the peephole 10 has been described as having two sensors, the proximity sensor 12 and the optical sensor 34. However, the peephole 10 may be configured to have either the proximity sensor 12 or the optical sensor 34. For example, if the peephole 10 has only the optical sensor 34, the actuator 51, which is a driving unit, may move the blades 52 from the second position to the first position when the optical sensor 34 detects the monocular lens 80 (second object). At least, the blades 52 may be moved to the first position when the monocular lens 80 is detected. This allows, for example, the blades 52 to be positioned in the second position under normal circumstances, allowing the resident to view the outside at any time. However, if a visitor engaging in privacy-invading behavior brings the monocular lens 80 close to the lens unit 101A, the peephole 10 can move the blades 52 to the first position. Therefore, the peephole 10 can prevent the visitor from taking photographs of the inside of the room. Furthermore, after moving the blades 52 to the first position, the actuator 51 may vibrate the blades 52 based on the vibration control shown in Fig. 10. This makes it possible to further intimidate visitors with the abnormal noise.

[0052] Furthermore, when the peephole 10 has two sensors, the proximity sensor 12 and the optical sensor 34, the blade opening / closing device 50 may be configured to operate as follows. If the optical sensor 34 detects the monocular lens 80 (second object) while the proximity sensor 12 detects an occupant (first object), the actuator 51, which is the driving unit, may move the blade 52 to the first position. When the proximity sensor 12 detects an occupant, the blade 52 moves to the second position, allowing the outside of the room to be viewed. In this state, if the optical sensor 34 further detects the monocular lens 80, the blade 52 moves, for example, from the second position to the first position. This configuration prevents the occupant from viewing the outside of the room through the peephole 10, but it also prevents the monocular lens 80 from being used to photograph the inside of the room when the occupant is approaching the peephole 10.

[0053] Furthermore, if the optical sensor 34 detects the monocular lens 80 (second object) while the proximity sensor 12 detects the resident (first object), the actuator 51, which is the driving unit, may vibrate the blade 52 based on the vibration control shown in Fig. 10. This makes it possible to scare off a visitor who tries to take pictures of the room using the monocular lens 80 while the resident is looking through the peephole 10 by making an abnormal noise.

[0054] Additionally, if the optical sensor 34 detects the monocular lens 80 (second object) while the proximity sensor 12 detects a resident (first object), the actuator 51 may move the blades 52 to the first position and then control the vibration of the blades 52. This allows the peephole 10 to intimidate visitors while preventing the interior of the room from being photographed.
