Configured. The rotary switch 125, the X and Y linear encoders 170, and the push switch 126 are operated in common with the rotary button 120.

  As shown in FIG. 2, the input device 1 is connected to an in-vehicle device 300 whose operation is controlled by the input device 1, and also displays, for example, an operation menu of the in-vehicle device 300 to display the rotary switch 125, X, Y linear. The encoder 170 is connected to a display unit 400 that displays a cursor or the like input on the operation menu.

  The input device 1 includes a base 110, a cover 111 covering the base 110, a rotary button 120 attached so as to protrude from the cover 111 so that an operator can operate, and a rotary switch 125 and a push switch 126 attached to the base 110. A knob shaft 130 having one end supported by a two-dimensional spherical bearing tiltingly supported in the X and Y directions and having a rotary button 120 attached to the other end, abutting the knob shaft 130 in the X direction and the knob shaft in the Y direction. X carriage 140 slidable in the X direction sliding with 130, and can be slid in the Y direction perpendicular to the X carriage 140 and in contact with the knob shaft 130 in the Y direction and sliding with the knob shaft 130 in the X direction Y carriage 150, X carriage 140 and Y carriage 15 Configured to include a voice coil motor 160 that force applied to each mounted, a linear encoder 170 for detecting the respective movement amounts in the X carriage 140 and Y carriage 150, to.

  Here, the X carriage 140 and the Y carriage 150 are supported by linear slide guides 180 attached to the base 110 and capable of sliding in the X and Y directions, respectively.

  The voice coil motor 160 includes a voice coil 161 fixed to the X carriage 140 or the Y carriage 150, and a magnetic circuit 165 formed by a magnet 166 and a yoke 167 made of a soft magnetic material. The voice coil 161 is formed by winding a predetermined conductive wire 162 in a coil shape, and is arranged so that the magnetic flux generated from the magnetic circuit 165 crosses the conductive wire 162. Thus, the voice coil 161 energized to the conductive wire 162 receives electromagnetic force according to Fleming's left-hand rule, and applies a driving force to the X carriage 140 or the Y carriage 150 to give a force sense to the operator. Can do.

  As shown in FIG. 2, the control unit 200 is connected to the rotary switch 125, the X, Y linear encoder 170, and the push switch 126 via an interface (not shown). The control unit 200 includes a CPU (Central Processing Unit), parameters such as threshold values, a storage unit that stores a control program, and the like.

  The rotary switch 125 outputs a signal corresponding to the rotation angle (position information P) in the θ direction of the rotary button 120 to the control unit 200. Alternatively, the detection pulse from the rotary encoder may be output to the control unit 200, and the control unit 200 may calculate the rotation angle by pulse counting. The X and Y linear encoder 170 outputs a pulse to the control unit 200 according to the movement of the rotary button 120 in the X and Y directions, respectively, and the control unit 200 integrates the operation speed V and the movement amount by the pulse count. (Position information P) is calculated. Various push switches 126 can be used as long as they can be turned ON / OFF by being pressed. Here, a device that outputs a steep output signal by ON / OFF operation is used (see FIG. 4A, etc.).

(Operation of the first embodiment)
When the operator moves the rotary button 120 in the X direction and the Y direction, a cursor or the like is displayed on the display unit 400 as indicating the input position. The cursor position on the display unit can also be moved by rotating the rotary button 120 by θ. The operator moves the cursor position on the display unit through the operation as described above, and adjusts the input position. After adjusting the input position, the push switch 126 is turned on by pressing the rotary button 120 in the Z direction to perform position input, and the control unit 200 determines and obtains position information.

Figure 4 operator time _{T 3} in (a) begins to press the push switch 126, as shown in FIG. 4 (b), the push switch 126 is turned ON at time _{T 0.} Here, the cursor position (position information P) may change during ΔT ₃ between times T _{3 and} T ₀ . This is because the XY position adjustment and the rotation adjustment are performed by the rotary button 120, so that the output of the rotary switch 125, the X, Y linear encoder 170 is shifted when the push switch 126 is pressed.

Therefore, as shown in FIG. 4C, the cursor position (position information P) at time T ₀ when the push switch 126 is actually turned on is not used as an input value, but only from ΔT ₁ from time T _0. cursor position in front of the time T ₁ (position information P) as input values. That is, based on the operating conditions of the input device unit (rotary switch 125, X, Y linear encoder 170), the position information a predetermined time before the position input operation is obtained.

  This will be described with reference to a flowchart for obtaining position information P by the control unit 200 (position determining unit) shown in FIG. It is determined whether or not the push switch 126 is turned on. If it is determined that the push switch 126 is turned on, the process proceeds to the next Step 2 (Step 1). If NO, repeat Step1.

  In Step 2, based on the operation conditions of the input device unit (rotary switch 125, X, Y linear encoder 170), a determination is made to obtain position information a predetermined time before the position input operation. When the operation speed V shown in FIG. 6D is equal to or lower than the predetermined threshold Vth, the process proceeds to Step 3, and otherwise, the process proceeds to Step 4.

When the operation speed V shown in FIG. 4D is equal to or lower than the predetermined threshold value Vth, the cursor position (position information P) at time T ₁ before the time T ₀ when the push switch 126 is turned on is used as an input value. (Step 3). Here, when the operation speed V is equal to or lower than the predetermined threshold value Vth, it is assumed that the operator slowly operates the rotary button 120 to perform fine alignment, and therefore the rotary shown in FIG. cursor position with a large time T ₁ of the previous pressing of the button 120 (position information P) is an input value.

On the other hand, when the operation speed V shown in FIG. 6D exceeds the predetermined threshold value Vth, the cursor position (position information P) at the time T ₄ before the time T ₀ when the push switch 126 is turned on is input. (Step 4). Here, when the operation speed V exceeds the predetermined threshold value Vth, it is assumed that the operator operates the rotary button 120 at the fast operation speed V and does not care about subtle misalignment. cursor position with a small time T ₄ of the previous pressing of the rotary button 120 shown in c) (position information P) is an input value.

  Since the position information P is obtained and determined by the control unit 200 as the position determining unit by any one of the above steps, the position can be input to the in-vehicle device 300 (Step 5).

(Second embodiment of the present invention)
The input device 1 according to the second embodiment of the present invention is different from the first embodiment in that the push switch 126 includes a pressure-sensitive sensor in addition to the ON / OFF function, and the other configurations are the same. is there. When the pressure sensor pushes the push switch 126, for example, as shown in FIG. 8A, the output of the pressure sensor increases from zero level to a certain level. In the push switch 126 including the pressure sensor, a threshold value Vth2 for detecting a so-called half-pressed state is set between the zero level and a certain level.

(Operation of the second embodiment)
This will be described with reference to a flowchart for obtaining position information P by the control unit 200 (position determining unit) shown in FIG. FIG. 8 shows signal waveforms during operation of the input device according to the second embodiment, and FIG. 9 is a waveform diagram when the pressure sensor is pressed twice. In the second embodiment using the provided push switch 126, the control can be performed by the flowchart shown in FIG. 7 in any case. Furthermore, even when the pressure sensor is pressed a plurality of times, it can be handled.

  The control unit 200 (position determining unit) determines whether or not the output of the pressure-sensitive sensor exceeds the threshold value Vth2, and if it is determined that the output exceeds the threshold value Vth2, the process proceeds to the next Step 12 (Step 11). If NO, repeat Step 11.

When the output of the pressure sensor exceeds the threshold value Vth2, the position information P is temporarily stored (Step 12). That is, the position information P at the time _{T 5} in FIG. 8 (a) (FIG. 8 (c)), or the control unit the position information P at the time _{T 6} in FIG. 9 (a) (to FIG. 9 (c)) The data is stored in the storage unit included in 200.

  Next, it is determined whether or not the output of the pressure-sensitive sensor has become equal to or less than the threshold value Vth2. If it is determined that the output has become equal to or less than the threshold value Vth2, the process proceeds to Step 14 (Step 13). If NO, the process proceeds to Step 15.

  In Step 14, the position information P once stored in the storage unit is discarded, and the process returns to Step 11.

If it is not less than the threshold value Vth2, it is determined whether or not the push switch 126 has been turned ON. (Step 15). That is, the cursor position (position information P) at time T ₅ or time T ₈ before time T _{0 when} the push switch 126 shown in FIGS. 8C and 9C is turned on is set as an input value. If it is not determined that the push switch 126 is turned on, the process returns to Step 13.

In the above flow, when the position information P at Step12 come back from Step14 are stored is in a state pushed so-called twice, position information at time _{T 8} in FIG. 9 (a) P (FIG. 9 (c) ) Is stored in the storage unit included in the control unit 200.

(Effect of the embodiment of the present invention)
The input device 1 according to the embodiment of the present invention has the following effects.
(1) Since the cursor position (position information P) at the time (T ₁ , T ₅ , T ₈ ) before the time T _{0 when} it is determined that the push switch 126 is turned on is used as the input value, the push switch 126 is Misalignment during pressing is alleviated. Accordingly, an input device that has a rotatable or slidable operation element and a determination button provided integrally therewith, is excellent in input operability, and corrects misalignment during input to provide an input device with high input accuracy. Can do.
(2) In the case of a car navigation device, for example, as the in-vehicle device 300, if the determination button is pressed after fine alignment such as map centering, the selected position at the aligned position is adopted. , It is possible to input at a desired position regardless of the positional deviation at the moment of pressing. This is particularly effective as an input device for an in-vehicle device mounted on a vehicle that is easily affected by vibration or the like.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from or changing the technical idea of the present invention. For example, the movement amount of the input device 1 in the X and Y directions is determined by the linear encoder 170. However, the absolute position may be detected by a potentiometer or the like. In the first embodiment, the operation speed V is detected at a speed that is ΔT ₂ before the time T ₀ when the push switch 126 is turned on, but may be an average speed from the time T ₀ to ΔT ₂ . In addition, in the second embodiment, apart from adding a pressure sensor, the push switch 126 is used as a two-stage moderation switch, and the detection process of the pressure sensor is performed at the first contact point ON and the push switch ON detection is performed at 2 steps. It may be replaced with the contact ON at the stage. Further, the push switch 126 may be eliminated, and the ON detection may be turned on when the detected value of the pressure sensor becomes a larger value. In this case, a larger value than the first detection threshold is set as the ON detection threshold.
