  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

(Configuration of optical touch panel)
FIG. 1 is a schematic diagram showing a schematic configuration of an optical touch panel according to an embodiment of the present invention. As shown in FIG. 1, the touch detection unit 20 is provided on the surface of the display panel 10 having a display area corresponding to the detection area E.

  The touch detection unit 20 has a rectangular detection area E in a rectangular frame 21. The touch detection unit 20 includes retroreflective plates 22a, 22b, and 22c that generate reflected light on the axis of the input light on the inner side surface of the left frame, the lower frame inner side surface, and the right frame inner side surface of the frame 21, respectively. The touch detection unit 20 includes an upper left detection unit 23a, an upper right detection unit 23b, a lower left detection unit 23c, and a lower right detection unit 23d at the upper left corner, the upper right corner, the lower left corner, and the lower right corner of the frame 21, respectively. Note that the lower left detection unit 23c and the lower right detection unit 23d are disposed at a distance d from the lower frame. This distance d is, for example, a value corresponding to the thickness of dust, snow, etc. deposited on the retroreflective plate 22b.

  The upper left detection unit 23a emits infrared rays toward the retroreflective plates 22b and 22c, and receives the reflected light from the retroreflective plates 22b and 22c. The upper right detection unit 23b irradiates infrared rays toward the retroreflective plates 22a and 22b, and receives reflected light from the retroreflective plates 22a and 22b. The lower left detection part 23c irradiates infrared rays toward the retroreflective plate 22c, and receives reflected light from the retroreflective plate 22c. The lower right detector 23d irradiates infrared rays toward the retroreflective plate 22a and receives reflected light from the retroreflective plate 22a. In addition, the infrared irradiation part of the upper left detection part 23a, the upper right detection part 23b, the lower left detection part 23c, and the lower right detection part 23d is implement | achieved by infrared LED, for example. Moreover, the infrared detection part of the upper left detection part 23a, the upper right detection part 23b, the lower left detection part 23c, and the lower right detection part 23d is implement | achieved by the infrared image sensor, for example. That is, the upper left detection unit 23a, the upper right detection unit 23b, the lower left detection unit 23c, and the lower right detection unit 23d are infrared light receiving and emitting devices.

  The retroreflective plates 22a, 22b, and 22c are striped tapes that reflect infrared incident light as reflected light in the same direction as the incident light, as shown in FIG. As shown in FIG. 2, the specific retroreflecting plates 22 a, 22 b, and 22 c have a large number of fine glass beads 15 that are glass spheres scattered on the surface, and a reflective film 16 is formed on the lower surface of the glass beads 15. doing. The retroreflecting plates 22a, 22b, and 22c can also be realized by a corner cube prism group in which a plurality of corner cube prisms are closely arranged in a plane. In this planar arrangement, it is preferable that the triangular entrance / exit surfaces of each corner cube prism are arranged densely. The corner cube prism is a triangular pyramid prism composed of three 90 degree right angles, and the reflected light always has a function of returning to the direction of the incident optical axis.

  The controller C is connected to the upper left detection unit 23a, the upper right detection unit 23b, the lower left detection unit 23c, the lower right detection unit 23d, and the display panel 10, and is connected to an external device (not shown). The controller C includes an operation determination unit 1 and a display control unit 2. The operation determination unit 1 determines whether or not the operation object has been touched based on the detection image of the operation object by the touch detection unit 20. Note that the operation determination unit 1 specifies the coordinate position on the detection area E where the operation tool is touched. The display control unit 2 performs display processing on the display panel 10 according to the touch position of the operating body determined by the operation determination unit 1.

(Detection operation by touch detection unit)
First, the upper left detection unit 23a and the upper right detection unit 23b can detect the entire surface of the detection region E, respectively. Further, the lower left detection unit 23c can detect a region on the right side of the detection region E with respect to the diagonal line with the upper right detection unit 23b. Moreover, the lower right detection part 23d can detect the area | region of the left side rather than the diagonal with respect to the upper left detection part 23a among the detection areas E. For example, as illustrated in FIG. 1, when an operation tool touches a position P on the right side of the detection region E, the upper left detection unit 23 a can obtain the detection image illustrated in FIG. 3. In this detected image, there is a shadow P1 in which infrared rays do not return due to the presence of the operating tool. Similarly, the upper right detection unit 23b can obtain a detection image in which the shadow P2 exists. Moreover, the lower left detection part 23c can obtain the detection image in which the shadow P3 exists. Note that the lower right detection unit 23d cannot obtain a shadowed detection image because the position P is outside the detection region. The operation determination unit 1 specifies the position P in the detection region E based on the three detection images having shadows P1, P2, and P3. The specification of the position P can be performed by triangulation such as a forward intersection method using two or more detection images having shadows.

(Detection operation when the reflection amount of the retroreflector 22b is reduced)
By the way, as shown in FIG. 4, since the detection area E is a layered space with an open front surface, dust, snow, and the like are likely to accumulate on the retroreflective plate 22b. For this reason, if dust, snow, or the like accumulates on the retroreflective plate 22b, the amount of reflected light from the retroreflective plate 22b is reduced, so that it is difficult to determine the shadow in the detected image, and the detection accuracy decreases. . That is, as shown in FIG. 4, the detection area of the upper left detection unit 23a is only the detection area Ea corresponding to the retroreflective plate 22c. Similarly, the detection area of the upper right detection unit 23b is only the detection area Eb corresponding to the retroreflective plate 22a. Therefore, in the conventional optical touch panel having only the two detection units of the upper left detection unit 23a and the upper right detection unit 23b, when the reflection amount of the retroreflective plate 22b is reduced, the detection regions are the detection regions Ea and Eb. Only the detection area Eab, which is an overlapping area, was provided.

  In this embodiment, a lower left detection unit 23c and a lower right detection unit 23d that do not use the retroreflective plate 22b are provided. As a result, as shown on the upper right side of FIG. 4, detection areas Ec and Ed that are vertically symmetrical with respect to the detection areas Ea and Eb by the two detection units of the upper left detection unit 23a and the upper right detection unit 23b are formed. As a result, as shown in the lower part of FIG. 4, even when the retroreflective plate 22b cannot be used, the four detections of the upper left detection unit 23a, the upper right detection unit 23b, the lower left detection unit 23c, and the lower right detection unit 23d. Two detection images can be obtained for the entire surface of the detection region E by the unit, and the touch position can be detected with high accuracy for the entire surface of the detection region E. Specifically, as shown in the lower part of FIG. 4, the upper area obtained by dividing the detection area E by a diagonal line overlaps the detection areas Ea and Eb, and the left area overlaps the detection areas Eb and Ed. The detection areas Ea and Ec overlap in the area, and the detection areas Ec and Ed overlap in the lower area.

(Detection operation when the reflection amount of the retroreflector 22b is normal)
When the retroreflective plate 22b is normally reflected, as shown in FIG. 5, the upper area E1 obtained by dividing the detection area E by a diagonal line overlaps the detection areas Ea and Eb, and the left area E2 is the detection area. Three regions Ea, Eb, Ed overlap, right region E3 overlaps three detection regions Ea, Eb, Ec, and lower region E4 includes four detection regions Ea, Eb, Ec, Ed. Two areas overlap.

  In this case, in a region where three or more detection regions are overlapped, two detection regions that are preferentially used in the touch position specifying process are set in advance. Then, another detection area is used as an auxiliary to the touch position specifying process. For example, two detection areas in each area shown in the lower part of FIG. 4 are set as priority detection areas. For example, in FIG. 5, in the left region E2, the detection regions Eb, Ed are set as the priority detection regions for the touch position specifying process among the detection regions Ea, Eb, Ed, and the detection region Ea is touched. It is set as an auxiliary detection area for position identification processing. When the auxiliary detection area is used, it is possible to specify a touch position with high accuracy. On the other hand, when performing quick touch position specification, a priority detection area may be used.

  In the above-described embodiment, the retroreflecting plate 22b is provided inside the lower frame. However, at least the retroreflecting plates 22a and 22c are provided, and the four upper left detection units 23a, the upper right detection unit 23b, and the lower left detection are provided. The part 23c and the lower right detection part 23d may be provided at the four corners of the frame 21, respectively. As a result, as shown in FIG. 4, two or more detection images are detected on the entire detection region E by two detection units of the upper left detection unit 23a, the upper right detection unit 23b, the lower left detection unit 23c, and the lower right detection unit 23d. And the touch position of the operating tool can be detected.

  In the above-described embodiment, the detection area E is provided. However, the touch detection unit 20 may be configured in a multi-stage configuration, and a plurality of detection areas E may be formed.

(Adherent removal structure of light emitting / receiving device)
FIG. 6 is a cross-sectional view of the deposit removal structure of the upper right detection unit 23b as a light emitting / receiving device as seen obliquely. FIG. 7 is a schematic diagram showing the flow of wind. As shown in FIGS. 6 and 7, the upper right detection unit 23b is covered with a cover 32a. The cover 32a is shielded from the outside air by sandwiching the upper right detection part 23b with the frame 21. However, the cover 32a has an opening 32b in a portion corresponding to the light emitting surface 40 and the light receiving surface 41 of the upper right detection unit 23b. The cover 32a communicates with a duct 31 that supplies wind. The blower fan 30 supplies wind to the cover 32 a through the duct 31. The cover 32 is a cover that covers the retroreflective plate 22c. The cover 32a also has a duct function.

  The wind A supplied from the duct 31 passes through the front surfaces of the light emitting surface 40 and the light receiving surface 41 and flows toward the opening 32b. Thereby, deposits such as dust and water droplets adhering to the light emitting surface 40 and the light receiving surface 41 are removed. In particular, since the wind A flows away from the light emitting surface 40 and the light receiving surface 41, it is possible to reliably prevent the intrusion of foreign substances from the outside.

(Modified example of deposit removal structure of light emitting / receiving device)
FIG. 8 is a cross-sectional view of a modified example of the deposit removal structure of the upper right detection unit 23b as a light emitting / receiving device as seen from an oblique direction. FIG. 9 is a schematic diagram showing a wind flow according to a modification. As shown in FIGS. 8 and 9, in this modified example, the cover 32a is provided with sub-openings 32c and 32d adjacent to the opening 32b. As a result, the winds A2 and A3 are generated via the sub-openings 32c and 32d in parallel with the wind A1 passing through the opening 32b, and the intrusion of the adhering matter due to the entrainment wind generated in the vicinity of the opening 32b can be reliably suppressed.

(Adherent removal timing)
The adhering matter removal timing may include a clock (not shown) and drive the blower fan 30 for a predetermined time after a predetermined time has elapsed. Furthermore, a rain sensor (not shown) is provided, and the blower fan 30 may be driven during a period in which the rain sensor detects rain. With these configurations, it is possible to save energy and efficiently remove deposits.
