(Configuration of the detection unit 10)
The detection unit 10 is, for example, a touch sensor that detects a position on the operation surface 100 that is touched by an operator's finger. Specifically, the detection unit 10 detects a change in current that is inversely proportional to the distance between a sensor electrode and a finger, which will be described later, due to the finger approaching or touching the operation surface 100. It is a sensor.

  For example, as illustrated in FIG. 2B, the detection unit 10 includes a plurality of sensor electrodes 101 and sensor electrodes 102, a detection control unit 103, and a determination unit 104.

  As an example, the detection unit 10 includes twelve sensor electrodes 101 arranged at equal intervals in parallel to the y axis and six sensor electrodes 102 arranged at equal intervals in parallel to the x axis. Insulated and disposed below the operation surface 100. The number of sensor electrodes 101 and sensor electrodes 102 can be freely changed as necessary. The x-axis direction is the horizontal direction on the paper surface of FIG. 2B, and the y-axis direction is the vertical direction of the paper surface. The origin of the xy coordinate system is the upper left of the operation surface 100 in FIG.

The sensor electrode 101 and the sensor electrode 102 are electrically connected to the detection control unit 103. In the following, the coordinates of the x-axis are indicated as x ₁ to x ₁₂ from the left to the right with a subscript number (1 to 12) appended to x. The y-axis coordinates are indicated by y ₁ to y ₆ from the top to the bottom with a subscript number (1 to 6) added to y. The sensor electrode 101 and the sensor electrode 102 are arranged according to the xy coordinates.

  The sensor electrode 101 and the sensor electrode 102 are formed using, for example, a conductive metal material. This metal material having conductivity is a material containing a metal such as copper or silver. The sensor electrode 101 and the sensor electrode 102 have, for example, a linear shape.

Detection control unit 103, for example, based on the control signal S ₁ output from the control unit 18 switches the connection between the sensor electrode 101 and sensor electrode 102, reads a detection value connected sensor electrode detects, and it is configured to output to the determination unit 104 as a detection value information S _2. Period of readout of the detected values, the time for reading the detected value of the sensor electrode 102 of the sensor electrode ~y ₆ of the sensor electrodes 101, _{y 1} of the sensor electrode 101～X ₁₂ of _{x 1,} as one example, is about 20ms . This detected value is a capacitance.

The detected value information S _2, for example, is configured to include information of the detected value of each sensor electrode of one period.

The determination unit 104 has a threshold value 104a. This threshold value 104a is used to determine whether or not a finger is detected. Determination unit 104, a detection value information _{S 2} acquired from the detector control unit 103 compares the threshold value 104a, and when the detected value is included in the detected value information _{S 2} is greater than the threshold value 104a, the It is determined that the sensor electrode that has detected the detection value has detected the finger.

Determination unit 104, the finger is configured to generate and output the detection information S ₃ containing information associating the detected value and the detected sensor electrode.

(Configuration of Area Calculation Unit 12)
FIGS. 3A and 3B are schematic diagrams for explaining the calculation of the contact area by the area calculation unit of the controller device according to the first embodiment. In FIGS. 3A and 3B, a region surrounded by a solid line and a dotted line indicates a contact region where the operation surface 100 and the finger 9 are in contact with each other. In FIGS. 3A and 3B, the circles described in the vicinity of the end portions of the sensor electrodes indicate the sensor electrodes in which the finger 9 is detected.

Area calculation unit 12, for example, on the basis of the detected information S ₃ obtained from the detecting unit 10 calculates the contact area is the area of the contact region, generating and outputting calculation information S ₄ including information on the calculated contact area Is configured to do. Below, an example of the calculation method of a contact area is demonstrated.

Area calculation unit 12 checks the sensor electrode 101 and sensor electrode 102 where the finger 9 is detected based on the detected information S _3. As shown in FIG. 3A, when the contact region 106 is formed by the finger 9 coming into contact with the operation surface 100, the sensor electrode that detects the finger 9 is included in the contact region 106, x sensor electrode 101 of the _fourth sensor electrode 101~x _7, the sensor electrode 102 of the sensor electrode 102～Y ₅ of _{y 3.}

That is, there are four x-axis sensor electrodes 101 that detect the finger 9, and three y-axis sensor electrodes 102. The area calculation unit 12 is configured to obtain the contact area 106 a of the contact region 106 by adding the number of sensor electrodes 101 and sensor electrodes 102 that have detected the finger 9. Therefore, the contact area 106a shown in FIG. Similarly, the contact area 107a shown in FIG. 3 (b), 2 Tsude sensor electrode 101 included in the contact region 107 _{x 5} and _{x 6,} the sensor electrodes 102, are two of _{y 3} and _{y 4} So it is 4.

(Configuration of change amount calculation unit 14)
The change amount calculation unit 14 is configured to calculate a change amount of the contact area (second contact area) in the (n + 1) period with respect to the contact area (first contact area) in the n period. This n is a positive integer.

  Further, the change amount calculation unit 14 is configured to store the contact area calculated by the area calculation unit 12 as the area information 140.

The change amount calculating unit 14 is configured to generate the variation information S ₅ containing the calculated amount of change.

  This amount of change is, for example, a difference obtained by subtracting the second contact area from the first contact area. Note that the amount of change is not limited to subtraction, and may be a ratio of the second contact area to the first contact area, a difference between detection values, or the like.

(Configuration of the comparison unit 16)
The comparison unit 16 has a change amount threshold 160. The comparison unit 16 is configured to compare the change amount calculated by the change amount calculation unit 14 with the change amount threshold 160.

  This comparison part 16 is comprised so that it may show by comparison whether the change of a contact area is abrupt. For example, when the operator performs an operation of tracing the operation surface 100, the change in the contact area is gentle because the operation is performed so that the finger is not separated from the operation surface 100. However, for example, when the operator releases the finger from the operation surface 100 in order to end the operation, the change in the contact area is larger than the change in the contact area during the operation, and the contact area Changes rapidly.

  In the present embodiment, the change amount threshold 160 is set to 2 as an example because the change amount (difference) in the number of sensor electrodes in which a finger is detected, that is, touched on, is obtained as the change amount. . Specifically, in FIG. 3A and FIG. 3B, the amount of change in FIG. 3A and FIG. 3B is that the number of sensor electrodes that detected the finger is 7, and the finger is detected in FIG. Since the sensor electrode is 4, it is 3. The comparison unit 16 compares the change amount of 3 with 2 of the change amount threshold value 160, and since the change amount> the change amount threshold value 160 holds, it can be determined that the change in the contact area is abrupt. It becomes possible.

  For example, the change amount threshold 160 is set based on the ratio of the second contact area to the first contact area. As an example, this ratio is preferably 70% or less, and more preferably 60% or less. In the present embodiment, as an example, the change threshold value 160 is set to 2 in order to set the rate of rapid change in the contact area to 60% or less.

(Configuration of control unit 18)
4A to 4D are schematic diagrams for explaining a change in the contact area of the finger that contacts the operation surface of the operation device according to the first embodiment. 4A and 4C illustrate how contact between the finger 9 and the operation surface 100 is resolved when the operator releases the finger 9 from the operation surface 100. FIG.

  The control unit 18 includes, for example, a CPU (Central Processing Unit) that performs operations, processing, and the like on acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. It is a microcomputer configured. In this ROM, for example, a program for operating the control unit 18 is stored. For example, the RAM is used as a storage area for temporarily storing calculation results and the like. Further, the control unit 18 has means for generating a clock signal therein, and operates based on this clock signal.

  For example, the control unit 18 has condition information 180, accumulated information 181, an area threshold value 182 and a time threshold value 183 in the RAM. The condition information 180 includes, for example, information on the above-described preset conditions. This preset condition includes, for example, a first condition, a second condition, and a third condition described below.

  The first condition is, for example, a condition where the finger is not detected, that is, the touch is turned off. The second condition is, for example, when the change amount is larger than the change amount threshold 160, the second contact area is set as the first contact area, and the calculated contact area after holding the calculated detection point The condition is that the difference between the first contact area and the second contact area is within a predetermined range, that is, the area threshold value 182 or less. The third condition is, for example, a condition that the retention of the calculated detection point exceeds a predetermined period, that is, longer than the time threshold value 183.

  Here, for example, when the operator performs a tracing operation on the operation surface 100 and separates the finger 9 from the operation surface 100, the contact state of the finger 9 is the belly of the finger 9 as shown in FIG. Changes from a state in which the tip of the finger 9 is in contact with the tip of the finger 9 as shown in FIG.

  While the operator performs the tracing operation, the finger 9 is operated by touching the belly portion of the finger 9, and when the finger 9 is released, the finger 9 moves away from the operation surface 100 in the order of the finger 9's belly to the fingertip. go. That is, as shown in FIGS. 4B and 4D, the contact area moves from the contact area 106 at the abdomen to the contact area 107 at the tip while reducing the area. If the operating device 1 calculates the detection point based on the contact area 106 and the contact area 107, it is calculated based on the contact area 106a of the contact area 106, as shown in FIGS. 4B and 4D. A difference d is generated between the detected point 106b and the virtual detected point 91a calculated based on the contact area 107a of the contact region 107.

  When the operation target of the controller device 1 moves according to the detection point, the operation is simply performed by moving the finger 9 away from the operation surface 100, that is, the operation target is desired not to move. The operation object moves, and this movement is unintended movement for the operator.

  Therefore, when the contact area changes abruptly so that the difference d does not occur, the controller device 1 is calculated based on the contact area 107a (second contact area) of the contact region 107. Instead of using 107b as a detection point, the detection point 106b calculated based on the contact area 106a (first contact area) of the contact region 106 is held as the detection point of the contact region 107.

  The second condition is a condition for releasing the holding of the detection point when the contact area returns to the original contact area, for example. Specifically, the controller device 1 calculates, for example, when the operator performs an operation of moving the contact region from the tip of the finger to the tip and then moving the contact region from the tip to the tip, that is, calculation. If the difference between the contact area calculated after holding the detected point and the second contact area that is the first contact area is within a predetermined range, the operation may be continued. Since it is high, it is configured to release the holding. If the difference between the calculated contact area and the second contact area that is the first contact area is within a predetermined range, the two contact areas are assumed to be equal.

  Further, for example, when the controller device 1 is configured to obtain the absolute value of the amount of change, the contact area suddenly changes when another finger touches the operation surface 100 without intention in the tracing operation. As a result, unintended movement of the detection point can be suppressed.

  The accumulated information 181 is information including, for example, information related to touch-on and touch-off in the previous cycle, information related to the contact area in the previous cycle, and the like.

  The area threshold value 182 is a threshold value related to the above-described predetermined range. As an example, the area threshold value 182 can be determined that the calculated contact area is the same as the second contact area as the first contact area when the change amount is 1 or less. Thus, 1 is set.

  The time threshold value 183 is a threshold value related to the above-described predetermined period. As an example, the predetermined period is 100 to 200 ms.

  Here, the change threshold value 160 and the area threshold value 182 are examples, and depend on the number of sensor electrodes 101 and sensor electrodes 102.

(Configuration of timer unit 20)
Timer unit 20 controls the holding timer 200 in accordance with the timer control signal S ₇ output from the control unit 18 is configured to perform a start and end time of the measurement.

The timer unit 20 is configured to store the time measured by the holding timer 200 as the measured time 201. The timer unit 20 is configured to generate time information S ₈ including information of the measurement time 201 measured by the holding timer 200 and output the time information S ₈ to the control unit 18.

  Below, operation | movement of the operating device 1 of this Embodiment is demonstrated according to the flowchart of FIG.

Control unit 18, when the preset condition is satisfied (S8: Yes), cancels the detection points holding, and outputs a timer control signal S ₇ to the timer unit 20 to stop the holding timer 200 ( S9), the process proceeds to step 1.

Here, in step 2, the control unit 18, when the finger is determined not to be detected (S2: No), generates operation information S ₉ indicating the non-detection state and outputs via the communication unit 22 (S10 ).

Moreover, in step 4, when it is touch-on from touch-off (S4: Yes), the control part 18 calculates a detection point based on the calculated contact area (S11), and operation information S based on the calculated detection point. ₉ is generated and output via the communication unit 22 (S12).

  Furthermore, in step 8, the control part 18 advances a process to step 1, when the preset conditions are not satisfy | filled (S8: No).

(Effects of the first embodiment)
The operation device 1 according to the present embodiment can suppress unintended movement of an operation target and improve operability. Specifically, when the contact area changes rapidly, the controller device 1 does not calculate the detection points for each detected contact area, but holds the detection points calculated before the change suddenly. Further, it is possible to suppress movement of the detection point not intended by the operator, for example, movement of the detection point based on a change in the position of the finger when an operation of pushing the operation surface 100 is performed.

  Further, when the contact area changes suddenly, the controller device 1 does not calculate a detection point for each detected contact area, so that it is possible to use a microcomputer with low processing capability, and the manufacturing cost is reduced.

As an example, the amount of change is preferably 50% or more, and more preferably 40% or less. Therefore, the change amount threshold 160 is set to a value such that the change amount is 40%, for example.
