Description of the Invention (1) [Background of the Invention] The present invention relates to retroreflective reflection of a light-emitting element to a light-receiving element by a retroreflective plate Type object detection device. Mainly to improve the prevention of misoperation of object detection. In the past, detection devices for detecting human bodies and the like are retroreflective object detection devices disclosed in Japanese "Japanese Patent Application Laid-Open No. 8-2 6 5 130". This detection device is composed of a device main body of a nano-light-emitting element and a light-receiving element, and a retroreflective plate disposed at a fixed distance from the device main body and arranged oppositely. This retro-reflective plate is composed of a reflector such as a corner cube reflector, so as to reflect the incident light of the light-emitting element in the reverse direction of the incident direction (ie, retro-reflection). If there is no object between the main body of the device and the retro-reflection plate, the light is projected: the projected light (infrared, etc.) of the element will be reflected by the retro-reflection plate to the light-receiving element. If an object (or human body, etc.) is present or passed between the device body and the retro-reflective plate, the light projection of the light projection element will be blocked by the object, which will affect the amount of light received by the light reception element. The light-receiving element senses the change in the amount of light received by the light reflected by the retro-reflective plate to detect the presence or absence of an object. In other words, if the light-receiving element cannot receive the light reflected by the retro-reflective plate, the device will send a signal, and the reporting department will issue an alarm to notify the existence of the object. The object detection device is characterized in that the light beam emitted by the light-emitting element needs to be narrow and concentrated, so that the reflected light reflected by the retro-reflective plate can be accurately irradiated on the light-receiving element, so that the light beam is not excessively diffused to prevent the occurrence of false alarms. But this kind of object detection device also has its disadvantages. Due to the narrowness of the light beam, it also responds to small targets that do not need to be detected and emits an alarm.

Description of the invention (2) Human body The device is a detection device, but an alarm is issued because a leaf or an insect passes through the vicinity of the light-emitting element to block light, and it is mistaken for someone to pass by. To eliminate the above disadvantages, both the light projection element and the light receiving element may be increased to two. As shown in FIG. 6 and FIG. 7, a device main body 100 equipped with rain light-emitting elements 1 101 and 101 and light-receiving elements 102 and 102 is provided. FIG. 6 shows that two light-emitting elements 101 and 101 are arranged side by side in the horizontal direction on the upper part of the light-receiving surface 10 of the device main body 100; two light-receiving elements are arranged side by side in the horizontal direction below the light-receiving surface 103. Element 1 〇2, 102. FIG. 7 shows that two light-emitting elements 1 0 1 and 1 0 1 are arranged side by side above and below one side (right side in the figure) of the light-emitting surface 10 3 of the device main body 10; On the other side (left side in the figure), two light-receiving elements 10 and 10 are arranged side by side in the up-down direction (in each figure, the light-emitting direction is indicated by arrows). Due to this configuration, a signal is emitted only when both of the light-emitting elements 10 1 and 101 are blocked. If only one small object blocked by the light-emitting element passes through, it will not emit a signal to avoid the occurrence of a signal. False positives. However, the above apparatus main body 100 still has the following disadvantages. As shown by the dotted line in FIG. 6, when the object 1 0 4 passes near the light-receiving surface 10 3 (such as when the horizontal object 104 falls), the light emitted by the two light-emitting elements 101 and 101 will be simultaneously emitted. Blocking sends a signal, causing the device to alert. In other words, an alarm is also issued when one half of the light receiving surface 103 is blocked. Similarly, when the same element is arranged side by side in the device main body 1 1 0 shown in FIG. 7, and the object 1 0 4 shown in dotted line in FIG. 7 passes near the light-receiving surface 10 3 (such as when an elongated object 10 4 passes in the up-down direction) ), Two paper sizes are applicable to China National Standard (CNS) A4 specifications (210 * 297 mm) II I -------- Ί ------- Order ---- line- -V.

Description of the invention (3) Light-emitting element 101, 101 The light will be blocked at the same time and send a signal 'causing the device to sound an alarm. In other words, when only half of the light-emitting surface 1 0 3 is blocked, an alarm will be issued. To prevent such false alarms, consider using two sets of device main bodies equipped with a light-emitting element and a light-receiving element, and placing them apart a certain distance, so that the two light-emitting elements are blocked by falling or passing objects at the same time. Easy to happen. However, this method requires double operation and two sets of equipment, which will inevitably increase costs. In addition, it is also possible to increase the size of the main body of the device, and arrange components at both ends of the light-emitting surface to increase the distance between the components to prevent false alarms. However, due to the large size of the device main body, this method needs to increase the installation space, cause deterioration in observation, and increase in manufacturing costs. [Objective and Summary of the Invention] The object of the present invention is to effectively prevent false alarms from occurring in a retroreflective object detection device composed of a plurality of light-emitting elements and light-receiving elements without increasing the size of the device. In order to achieve the above-mentioned objective, the retro-reflective object detection device of the present invention is a retro-reflective configuration of a device body equipped with a light-emitting element and a light-receiving element on the light-receiving surface and a fixed distance from the device body. Composed of split processing. The light irradiated by the light-emitting element can be reflected to the light-receiving element through the retro-reflective processing device, and whether the light-receiving element can receive the reflected light of the retro-reflective processing device is used to determine the presence or absence between the device body and the retro-reflective processing device.

Description of the invention (4) A complex array of light-receiving elements consisting of a light element and a light-receiving element. A column contains more than one matrix configuration. The light-emitting elements and light-receiving elements arranged in this matrix configuration can be specified in the row and column directions according to the size of the object to be detected, making small objects that are not to be detected. When passing or existing, unless all the light-emitting elements are blocked, the light emitted by the light-emitting elements cannot be completely blocked. In other words, the size of the detected object must be greater than the horizontal or vertical width of the light-emitting element in order to cover all light-emitting elements. The reflected light is also blocked in the same way. It needs to be equal to or larger than the light receiving element or the reflecting device to cause the reaction. If it is only half blocked (see Figure 6 and Figure 7), no alarm will be issued to avoid malfunction. In the above arrangement, it is better to use the light-emitting elements to be arranged separately in one of the rows and columns of the matrix-the farthest position in the diagonal direction, and then to arrange the light-receiving elements in the other farthest position in the diagonal direction. This configuration can make maximum use of the area of the light-receiving surface, and place each light-emitting element and each light-receiving element separately. In this way, the existence of an object will not be sensed unless two light-emitting elements or two light-receiving elements are blocked by the object at the same time. Therefore, it is possible to reliably prevent the alarm from being issued for small objects that need not be detected. In the above configuration, it is better to set the horizontal distance from the furthest two light-emitting elements and the horizontal distance from the furthest two light-emitting elements to be smaller than the horizontal size of the object to be detected. At the same time, the top and bottom distances of the two farthest projection elements and the top and bottom distances of the two farthest projection elements are set smaller than the top and bottom dimensions of the object to be detected. When configured in this way, the reliability of the device can be improved.

Description of the invention (6) The main body of the device 3 is characterized by the configuration and installation state of each component 5 1, 5 2, 6 1 '6 2. Of the corner portions of the light-receiving surface 3 2, light-emitting elements 5 1 and 5 2 are respectively installed on one corner portion of the diagonal line, and the light-receiving elements 6 1 and 1 are respectively provided on the other corner portions. 6 2. In other words, the light-emitting elements 5 1 and 5 2 are not arranged adjacently in the horizontal or vertical direction (both are diagonally adjacent configurations), and the light-receiving elements 61 and 62 are not arranged adjacently in the horizontal or vertical direction (both are diagonally adjacent configurations) . Specifically, in the upper left corner and the lower right corner of FIG. 2, light-emitting elements 5 1 and 5 2 are respectively disposed, and the upper right corner and the lower left corner are respectively provided with light receiving elements 6 1 and 6 2 (FIG. 2 The arrows indicate the path of the light to be received and received). Another configuration method can also be adopted. As shown in Fig. 2, a light projection element is arranged on the upper right corner and a lower left corner, and a light receiving element is arranged on the upper left corner and the lower right corner. Horizontal distance L 1 値 between the center position points 5 1 1 and 5 2 1 of each light-emitting element 5 1 and 5 2 and horizontal center 6 1 1 and 6 2 1 between each light-receiving element 6 1 and 6 2 The directional interval L 1 値 needs to be set to a size smaller than the width of the human body (such as 100 mm). That is, if anyone is standing in front of the main body 3 of the device, the two light-emitting elements 5 1, 5 2 and the two light-receiving elements 6 1, 6 2 are blocked by the human body, so that the light-emitting elements 5 1, 5 2. The light cannot reach the retro-reflective plate 4. The above is the device 1 for detecting human body, so the horizontal dimension L 1 is specified. When detecting other objects, depending on the situation, the interval between the top and bottom of each element can be set to be smaller than the size of the detected object. ^ The retroreflective plate 4 is a corner cube. -The paper size of the note page of the back Sj 'is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) -9 A7 4 6 8 03 6 B7___ V. Description of the invention (7) reflector) The structure can retroreflect the light emitted from the light projection elements 5 1 and 5 2 (reflect in the opposite direction of the incident direction). This retro-reflective plate 4 can reflect the light emitted by 51, one of the light-emitting elements, to each of the light-receiving elements 61, 62, or the light emitted by 52, one of the light-emitting elements, to each light-receiving element. 61, 62 reflection. As shown in FIG. 1, the device main body 3 is connected to the transmitting unit 7 of the detection device 1. This transmitting unit 7 can receive the signals of the two light receiving elements 6 1, 62. If _ 6 1, 6 2 cannot receive the reflected light of the retro-reflective plate 4, it will send a signal to the transmitting unit 7, which will start the ATM. 2 signal. The detection device 1 constructed as described above detects the human body as an example, and will be described later. When no one approaches the ATM 2, the light rays (infrared, etc.) emitted by the light-emitting elements 5 1, 5 2 are reflected by the retro-reflective plate 4 and hit the light-receiving elements 6 1, 6 2. In this case, the transmitting section 7 will not send a signal, and of course the ATM 2 will not start. If someone approaches the ATM 2, between the device body 3 and the retro-reflective plate 4 (in front of the ATM operating panel), someone intrudes, and the light emitted by the two light-emitting elements 5 1, 5 2 is blocked by the human body, resulting in the light-receiving element. The light receiving amount of 6 1 and 6 2 is changed and a signal is sent to the transmitting section 7. When the transmitting unit 7 receives the signal, it starts the ATM (such as lighting the monitor screen lights, etc.). The two light-emitting elements 5 1 and 5 2 or the two light-receiving elements 6 1 and 6 2. They are not arranged side by side in the horizontal or vertical direction, so the following (A) or (B) erroneous sending will not occur.

Description of the invention (8 ) Condition. (A) As shown by the imaginary line in FIG. 3 (a), when a long horizontal object 70 passes (falls) near the light-receiving surface 32, 5 1 which is one of the light-emitting elements and one of the light-receiving elements 6 1 will be blocked by this object 70, but the other set of light-emitting elements 5 2 and light-receiving element 62 will not be blocked by this object 70, and of course, it will not send a signal "so the reporting unit 7 will not send Signal, the ATM 2 will not cause malfunction. (B) As shown by the imaginary line in Fig. 3 (b), when an object 7 1 with a long vertical direction passes near the light-receiving surface 3 2, 5 2 of one of the light-emitting elements and 6 1 of one of the light-receiving elements will Obstructed by this object 71, the other group of light projection elements 51 and 62 are not blocked by the object 71. Therefore, the transmitting section 7 will not send a signal, and the ATM 2 will not cause malfunction. From the above, it can be seen that if only half of the light-receiving surface 32 is blocked, the transmitting section 7 will not emit a signal. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page) If the detection device 1 has a special shape as shown in Figure 4, a special-shaped object 7 3 will send a signal. When such an object C passes or exists, the two light-emitting elements 5 1 and 5 2 are blocked by the object 7 3. Therefore, the two light-receiving elements 6 1 ′ 6 2 cannot receive the reflected light from the retro-reflective plate 4 and therefore will A signal is sent to the sending section 7, and the sending section 7 sends a signal upon receiving the signal, so the device 1 will activate the ATM or issue an alarm. However, in fact, there are very few special-shaped objects similar to the above-mentioned object 7 3. Under normal circumstances, it should be assumed that the light-receiving surface 3 2 is completely blocked and the device 1 will issue an alarm. As shown in Fig. 6 and Fig. 7, even if the conventional device is equipped with two light-emitting elements and light-receiving elements, when the paper size of the project is applied to the Chinese National Standard (CNS) A4 specification (210 X 297 mm > 4 6 8 03 6 A7 B7 V. Description of the invention (9) The signal will be emitted when half of the light-receiving surface range is blocked. However, even when the light-emitting element 5 1 and 5 2 and the light-receiving element 6 1 and 6 2 are not provided in the device of the present invention ' It is also necessary that the light-receiving surface 3 2 be blocked by all objects (such as the human body) before sending a signal. As described above * The device body 3 of this detection device is equipped with two light-emitting elements 51, 52 and two light-receiving elements 6 1, 62, and two light-emitting elements 5 1 and 5 2 or two light-receiving elements 6 1 and 6 2 are not arranged next to each other horizontally or vertically, so only the light-emitting surface 3 2 is blocked by the human body and the like Only when the device 1 sends out a warning signal. This can avoid the shortcoming that the light-receiving surface is only half-blocked by an object and sends out a warning signal. Therefore, it will not cause false alarms due to the alarm caused by the interference of small objects. In other words, the device body 3 does not Need to increase the volume of the device body, and do not need multiple investment The light element can prevent false alarms. In order to provide a high-reliability detection device without increasing the number of installation devices, manufacturing costs, or appearance of the detection device, the above-mentioned embodiment is a retroreflective object of the present invention The detection device 1 is installed on the ATM 2 as an example, but the application of the present invention is not limited to this.
