Embodiment 3 FIG.
The third embodiment will be described using the configuration of the open / close lid detection device 202 shown in FIG. In the third embodiment, the first sensor 206 and the second sensor 208 shown in FIG. 6 are magnetic sensors using detection elements such as MR (Magneto Resistive) elements or Hall elements. The first detection target component 205 and the second detection target component 209 are magnets. In the third embodiment, the storage operation of the opening / closing lid 201 that opens and closes the vent 200 is the same as the storage operation of the opening / closing lid 201 of the second embodiment. In the third embodiment, the posture in which the detection target device 203 is installed is the same as the posture of the opening / closing lid 201 in the second embodiment.

  In the third embodiment, the positional relationship among the first sensor 206, the second sensor 208, the first detection target component 205, and the second detection target component 209 will be described with reference to FIG. The first sensor 206 has a detection range 400 for detecting a change in magnetism of the second detection target component 209. The second sensor 208 has a detection range 401 for detecting a change in magnetism of the first detection target component 205. The first sensor 206 is installed at a position where the magnetic change of the second detection target component 209 can be detected within the detection range 400. The second sensor 208 is installed at a position where the magnetic change of the first detection target component 205 can be detected within the detection range 401. The first sensor 206 and the second sensor 208 have the structure shown in FIG. 8, so that the first sensor 206 and the second sensor 208 are shown in FIG. 7 depending on whether or not the first detection target component 205 and the second detection target component 209 are detected. Storage of the open / close lid 201 can be detected.

  In the third embodiment, a magnetic sensor that detects a change in magnetism when the magnet approaches a distance of 1 mm to 2 mm may be applied to the first sensor 206 or the second sensor 208. By setting the distance between the magnetic sensor and the magnet relatively short, the movement of the panel can be grasped more accurately, and the magnetic flux density is relative to that of a rare earth magnet having a relatively high magnetic flux density. And an inexpensive ferrite magnet can be used. A magnetic sensor using a detection element such as an MR element or a Hall element is easily available, and generally has a configuration for detecting a change in magnetism within a distance range of 1 mm to 2 mm. For this reason, the distance between the magnetic sensor and magnetism is a useful element in configuring the sensor. In the third embodiment, as shown in FIG. 8, the first detection is performed within a distance in which magnetism can be detected without moving the position of the first sensor 206 or the second sensor 208 on the display substrate 207. By arranging the target component 205 or the second detection target component 209, it is possible to detect a change in magnetism. In the third embodiment, the distance for detecting the magnetic change of the first sensor 206 or the second sensor 208 has been described in the range of 1 mm to 2 mm.

The number of In the third embodiment, the number of wirings that are electrically connected to the substrate and the sensor is reduced as compared with the conventional technique, so that the wiring space can be reduced.

  Note that the opening / closing lid detection device 202 shown in FIG. 7 is configured such that when the sensor that detects the magnetism of the detection target component without distinguishing the magnetic poles is applied to the first sensor 206, Sensor 206 may detect the approaching second detection target component 209, and may not be able to accurately detect the position of the open / close lid 201. Therefore, in the third embodiment, Hall elements that can detect and detect the N pole and S pole of a magnet that is a detection target component may be used for the first sensor 206 and the second sensor 208. Specifically, an N pole detection Hall element that can detect the N pole is applied to the first sensor 206. The first detection target component 205 is a magnet that is magnetized so that the magnetic pole detected by the first sensor 206 is an N pole. A magnet magnetized so that the magnetic pole detected by the second sensor 208 is an S pole is applied to the second detection target component 209. In this case, in the second embodiment, the first sensor 206 distinguishes the magnetic poles of the first detection target component 205 and the second detection target component 209, so that the first sensor is closed when the vent 200 is closed. It is possible to prevent erroneous detection when 206 approaches the second detection target component 209.

  FIG. 9 is a diagram illustrating a detection target device 303 including the opening / closing lid detection device 302 according to the third embodiment.

The detection target component 305 is a conductor. 10 is a sectional view taken along line VIII-VIII in FIG. In the detection target device 303 illustrated in FIG. 10, the storage operation of the opening / closing lid 301 that opens and closes the vent 300 is the same as the storage operation of the opening / closing lid 201 of the second embodiment. In the detection target device 303 illustrated in FIG. 10, the posture in which the detection target device 303 is installed is the same as the posture of the opening / closing lid 201 of the second embodiment.

  FIG. 11 is a diagram illustrating an arrangement relationship of the first sensor 306, the second sensor 308, and the first detection target component 305. The first sensor 306 has a detection range 500 for detecting a change in capacitance of the first detection target component 305. The second sensor 308 has a detection range 501 for detecting a change in capacitance of the first detection target component 305. The first sensor 306 is installed at a position where the change in capacitance of the first detection target component 305 can be detected within the detection range 500. The second sensor 308 is installed at a position where a change in capacitance of the first detection target component 305 can be detected within the detection range 501. The first sensor 306 and the second sensor 308 have the structure shown in FIG. 11, and detect the storage of the opening / closing lid 301 shown in FIG. 10 according to whether the first detection target component 305 is detected. be able to.

  In Embodiment 3, a touch sensor that detects a change in capacitance when a conductor approaches a distance of 1 mm to 3 mm is applied to the first sensor 306 or the second sensor 308 shown in FIG. May be. By setting the distance between the touch sensor and the conductor to be relatively short, the movement of the panel can be grasped more accurately. A general touch sensor that detects a change in capacitance when a conductor approaches a distance of 1 mm to 3 mm is easily available. A highly sensitive touch sensor that detects a change in capacitance when a conductor approaches a distance of 10 mm is more expensive than a general touch sensor. In addition, a touch sensor with higher sensitivity than a general touch sensor may erroneously detect that the open / close lid is approached when the user approaches. For this reason, the distance between the touch sensor and the conductor is a useful element in configuring the sensor. In the third embodiment, when a general touch sensor is applied to the first sensor 306, the first detection target component 305 is disposed at a distance of about 1 mm to 3 mm, which is a distance capable of detecting the conductor. Thus, detection of a change in capacitance can be performed. In addition, when a general touch sensor is applied to the first sensor 306, the first sensor 306 is disposed at a distance of about 1 mm to 3 mm, which is a distance capable of detecting the conductor, so that the capacitance can be increased. Change detection can be performed. In Embodiment 3, the distance for detecting the change in capacitance of the first sensor 306 or the second sensor 308 has been described in the range of 1 mm to 3 mm, but is not limited to this range.

  The open / close lid detection device 302 shown in FIG. 9 includes the display substrate 307 on which the first sensor 306 and the second sensor 308 are mounted, so that the number of wirings that are electrically connected to the substrate and the sensor compared to the related art. Decrease. Further, in the open / close lid detecting device 302 shown in FIG. 9, the number of wirings that are electrically connected to the substrate and the sensor is reduced as compared with the conventional technique, so that the wiring space can be reduced.

  Here, by applying a metal such as aluminum or copper to the opening / closing lid 301 shown in FIG. 9, the first sensor 306 and the second sensor 308 are brought close to the opening / closing lid 301 or moved away from the opening / closing lid 301. It is good also as a structure which detects the change of the electrostatic capacitance which arises. In this case, in the third embodiment, since it is not necessary to install the detection target component 305 with respect to the opening / closing lid 301, the man-hour and the number of components for arranging the detection target component 305 can be reduced.

  FIG. 12 is a diagram illustrating a display substrate 307 provided in the open / close lid detection device 302. The display substrate 307 includes a first sensor 306, a second sensor 308, a touch electrode 321, a touch electrode 322, and a control substrate 320.

A conductor is disposed. Further, the second sensor 308 contacts the surface of the second sensor 308 toward the detection target component 305 included in the opening / closing lid 301 when the opening / closing lid 301 for opening the vent 301 is stored.
