The control unit 19 passes, via the optical receiver 15, the first received radiation 7.1 reflected by the surface of the first light field 30 and the second reception reflected by the surface of the second light field 20. Receives radiation 7.2. The control unit 19 determines that the reflected second received radiation 7.2 generated by the monitoring object 9 detected in the monitoring area 3 has changed, and that the monitoring object 9 has made a predetermined change described later. An output signal (SAus) is generated when detected by the received radiation 7.1.

  As shown in FIG. 3, the invisible first light field 30 is composed of a plurality of invisible radiators 32 that are circular or elliptical. The second light field 20 that is visible is located at approximately the center of the first light field 30 and is surrounded by the first light field 30 with a single visible light spot of a predetermined diameter. is there. The second light field 20 is located at a predetermined distance from the first light field 30.

  The monitoring object 9 moving in the two light fields 20 and 30 can be detected by the reflection state of the two light fields 20 and 30. The two light fields 20, 30 are directed in one direction, so that the monitored object 9, ie the user's foot, does not affect the first light field 30 in multiple directions. It can be positioned in the second optical field 20 only by the influence from the above. For example, when an object such as an animal or a ball passes through the monitoring region 3, it passes through the region of the circular first light field 30, so that not only the first light field 30 in the approach direction, The state of reflection passes through the second light field 20 and changes in the first light field 30 in the retracting direction.

This makes it possible to easily assign the reflected first or second received radiation 7.1, 7.2 to the first or second light field 30,20. Accordingly, the second optical transmitter 12 may have a second frequency region that includes frequencies of the invisible or visible light spectrum. This means that the second optical transmitter 12 can generate an invisible second optical field 20 or a visible second optical field 20 on the surface of the monitoring area 3. That is, when the second optical transmitter 12 emits the second transmission radiation 5.2 with an invisible light spectrum, the third optical transmitter 13 marks the position of the second optical field 20; Alternatively, it can be used for visualization.

Here, the individual radiators 32 of the first light field 30 can be set to be located at a predetermined distance from the single radiator of the second light field 20.

  As shown in FIG. 4, the control unit 19 controls the first optical transmitter 11 and the second optical transmitter 12 based on the Helios measurement principle to identify at least one object. The received radiation 7.1, 7.2 received by the optical receiver 15 is evaluated based on the Helios measurement principle.

  For this purpose, the optical measuring device 10 modulates the fourth optical transmitter 14, the first optical transmitter 11 and the second optical transmitter 12 having at least one correction light emitting diode. The first modulator 16, the second modulator 17 for modulating the fourth optical transmitter 14, and the synchronous demodulator 18 are included. In order to apply the Helios measurement principle, the fourth optical transmitter 14 includes a correction light emitting diode (not shown) for the first optical transmitter 11 and the second optical transmitter 12, and this corrected light emission. The diode also operates in the same manner as the first optical transmitter 11 and the second optical transmitter 12 by the time division multiplexing method.

  In this embodiment, in FIG. 10 to FIG. 12, when the change position of the return light in the second display does not coincide with a predetermined ratio before and after the change of the return light in the first display, it is determined in advance. It is determined that the condition is satisfied. Therefore, since the motion input mode can be added to the operation input, operation input with a plurality of patterns is possible.

  Although it is possible to discriminate between normal operation and motion input according to the above conditions, there are cases where it is not possible to discriminate between motion input and foreign object passage only under the above conditions. Therefore, the determination method will be described with reference to FIGS. 13 and 14. FIG. 13 shows the positional relationship of the return light change position group in the second display when entering and retracting when the motion is input, and FIG. 14 is the return light change position group in the second display when the foreign object passes. The positional relationship is shown. From FIG. 13, the distance between the clockwise start points of the return light change position group in the second display that forms a continuous display form before and after the change in the return light in the first display is X. In the case of 14, X ′. Also, from FIG. 13, the distance between the clockwise end points of the return light change position group in the second display which forms a continuous display form before and after the change in the return light in the first display is Y, and similarly In the case of FIG. 14, Y ′. That is, when the foreign object is a ball having the size shown in FIG. 14, there is a difference between the lengths X and Y when the motion is input, but the lengths X ′ and Y ′ when the foreign object passes are almost the same. It will be the same. Therefore, if the above relationship is detected, an abnormal operation due to passage of a foreign object or the like can be detected, and all processing can be prohibited. Therefore, the conventional function can be secured while adding a new function.

  In addition to determining whether or not a foreign object has passed according to the relationship between the direction of motion input and the direction of retraction, the condition may be that the motion input is performed within a predetermined time. That is, on condition that a predetermined motion is input within a predetermined time, for example, even if a small animal accidentally establishes the relationship between the direction of entry and retraction of motion input, Since it is possible to stay on the spot or to pass through quickly, such accidental misoperation can be avoided.

  The processing of the vehicle opening / closing body control device is recorded on a recording medium readable by the computer system, and the program recorded on the recording medium is read into the vehicle opening / closing body control device and executed, thereby executing the vehicle opening / closing body of the present invention. A control device can be realized. The computer system here includes an OS and hardware such as peripheral devices.

  Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW (World Wide Web) system is used. The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.

  The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient.

  The embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to the embodiments, and includes designs and the like that do not depart from the gist of the present invention.
