Description

  The present invention relates to a touch-sensitive fader operation element capable of detecting an operation position operated by a part of a body approaching or contacting, and an operation element device including the same.

  Various electronic devices such as electronic musical instruments such as electronic pianos and electronic organs, and acoustic devices such as mixer devices, such as switches for selecting functions such as various acoustic effects and adjusting volume and tone, etc. An operation device having an operation device is provided. In addition, in this type of operation device, in addition to a detection unit such as a switch for detecting various operations, there may be a case where a display unit including a light emitter for visually displaying an operation state is provided. Many. As a conventional example of such an operator device, there is a fader mechanism described in Patent Document 1.

  The fader mechanism described in Patent Document 1 is a mechanical fader mechanism, and a slider knob for moving with a finger is attached based on a linear slide volume (variable resistance) or a linear encoder. It is used to read the resistance value that changes by moving the position of the slider knob on the slide rail and to continuously change the parameters of the device to be operated. The operation amount (level) operated by such manual operation is detected, and for example, the fader gain of the corresponding input channel is adjusted according to the detected level. And in the fader apparatus shown in patent document 1, the lamp | ramp which comprises a display is arranged in the side part (side part with respect to the sliding direction of a slider knob) of an operation element.

  Another conventional example of the operation device is an illuminated operation device described in Patent Document 2. The operating element device described in Patent Document 2 includes an operating element provided on the lower surface side of the transparent panel, the operating element having a recess formed by a partition, and a light detection element at the center of the recess. And an illuminating element for indicating that the operating element has been selected is disposed around the illuminating element, and a light-shielding cylindrical body is provided between the light detecting element and the illuminating element. It will be. The light detecting element of the operation unit is always turned on by receiving light from the upper light source, and a finger is placed on the transparent panel to cover the upper part of the light blocking cylindrical body. This constitutes an optical switch that is turned off when the irradiated light is blocked. A plurality of such operation elements are arranged in a straight line, and a finger slides on the upper surface of the transparent panel along the arrangement direction, so that the movement is continuously detected.

  As another conventional example of the operator device, there is an operator device (operator unit) described in Patent Documents 3 and 4. The operation unit described in Patent Documents 3 and 4 includes a plurality of push button switches arranged in a straight line, and an illumination unit including a light emitting diode (LED) arranged on one side of the push button switches with respect to the arrangement direction. I have. Then, by continuously operating a plurality of pushbutton switches with a finger along the arrangement direction, the movement is detected and the operation state is displayed on the illumination unit.

  However, the conventional operating device has the following problems. That is, in the operation device described in Patent Documents 1, 3, and 4, the display device is arranged on the side portion with respect to the sliding direction of the operation unit. If the display device is arranged away from the side of the operation unit in this way, the operation sensation of the operation unit and the display position of the display unit are difficult to match intuitively and it is difficult to perform sensory operations. is there. Further, if the display device is arranged away from the side of the operation unit, the size in the width direction of the operation device increases accordingly, which hinders the downsizing of the installation area.

  In addition, in the operation device described in Patent Document 2, a plurality of operation portions including a light detection means and a switch for detecting an operation are provided side by side, and they are not continuous along the arrangement direction. In other words, it is arranged in a stepping stone shape. Therefore, the detection signal for the slide operation in which the finger or the like slides linearly becomes a stepped shape, and the slide operation cannot be detected continuously (smoothly).

  In addition, there is a problem that the frequency of erroneous detection is high in the detection of an operation by a light detection unit such as the operation device described in Patent Document 2. Therefore, it is common to perform signal processing with modulation in order to reduce the frequency of erroneous detection. As a result, the configuration may be complicated and the cost of the apparatus may increase.

  Also, instead of the mechanical switches and light detection type controller devices as described above, recently, it has been detected that a part of the body such as a finger has approached or contacted the electrode by a change in capacitance. An operator device composed of a configured capacitance sensor is often used. As an example of an operator device composed of such a capacitance sensor, there is a device disclosed in Patent Document 5. In the apparatus described in Patent Document 5, position information of a finger sliding with an electrostatic capacitance sensor is detected.

  However, the operator device described in Patent Document 5 has a complicated structure or principle and may lead to an increase in size of the device. In addition, in the case of the operation element device including the conventional electrostatic capacity sensor including the operation element device described in Patent Document 5 that is configured to continuously detect the sliding movement of the finger, the detection electrode Is divided in the middle, the detected value becomes stepped. Therefore, the display unit for displaying the operation state cannot be provided inside the sensor region, but is provided outside the sensor region.

On the upper surface 41a side of the fader substrate 41, as shown in FIGS. 4A and 5A, a fader unit 43 for detecting the approach or contact of a finger operating the fader operation element 40 is provided. Yes. The fader unit 43 has an electrode unit 45 formed in a rectangular shape along the longitudinal direction of the fader substrate 41, and the electrode unit 45 detects the operation position of the finger.

  A plurality (13 in the figure) of window portions (openings) 43a are arranged at predetermined intervals along the longitudinal direction at the center in the width direction with respect to the longitudinal direction of the electrode portion 45. The window portion 43 a is a portion having translucency for guiding the light emitted from the LED element 23 installed on the circuit board 20 to the fader portion 43. In this embodiment, the window 43a is made of an opening formed in the fader substrate 41.

  On the other hand, as shown in FIG. 4B, an elastic holding body 46 made of a projecting frame projecting downward is attached to the lower surface 41 b of the fader substrate 41. The elastic holder 46 is a member made of an elastic material such as a synthetic resin material that is bonded and fixed to the lower surface 41 b of the fader substrate 41, and is formed in a rectangular frame shape that follows the outer shape of the fader portion 43. The elastic holding body 46 is formed with a substantially rectangular opening 46a penetrating vertically, and a light guide 47 is fitted and installed in the opening 46a. The light guide 47 is a long square member made of a transparent or translucent synthetic resin material having translucency, and as shown in FIG. The convex part 47a of the shape fitted to the window part 43a of 41 is formed. A plurality of convex portions 47 a corresponding to the window portions 43 a are arranged in a straight line along the longitudinal direction of the light guide 47. On the other hand, a recess 47 b for accommodating and arranging the LED elements 23 on the circuit board 20 is formed on the lower surface of the light guide 47. Each concave portion 47b of the light guide 47 is formed at a position corresponding to each convex portion 47a. The window portion 43 a, the light guide body 47, and the LED element 23 mounted on the circuit board 20 constitute a display portion 48 that displays the operation position of the fader portion 43 by light emission of the LED element 23.

  The fader substrate 41 on which the electrode part 45 is formed is a printed wiring board composed of a multilayer substrate. The width dimension of the electrode part 45 is set to a dimension (for example, about 1.0 to 1.2 cm) of 1/2 or more of the width of the finger to be operated. As shown in FIG. 5A, the electrode unit 45 includes a plurality of electrode patterns M1, M2,... Along a direction in which a finger to be operated slides (hereinafter, this direction is referred to as “slide direction”). M6 is arranged side by side continuously. Between the adjacent electrode patterns M1, M2,..., Strip-like boundary portions (partition portions) L1, L2,. As shown in the partial enlarged side sectional view of FIG. 5C, the electrode pattern Mi is a portion formed by sticking a copper foil 45a on the circuit board 20, and the boundary portion Li is on the circuit board 20. This is a portion where the copper foil 45a is removed (etching). Furthermore, the upper surface of the electrode pattern Mi and the boundary portion Li is covered with a resist layer 44 made of an insulating material, and a cover sheet 42 covering the upper surface is further adhered and covered.

  The boundary portions L1, L2,... Have a shape in which a plurality of linear boundary lines inclined obliquely with respect to the sliding direction are folded back, and a plurality of peak portions and valley portions are continuously formed. It is a letter shape. Therefore, a plurality of boundary portions L1, L2,... Exist at the same position in the sliding direction (for example, the position Q shown in FIG. 5A). That is, there are two adjacent electrode patterns M1, M2, M2, M3,... At the same position crossing one place in the sliding direction (in the illustrated portion, electrode patterns M3 and M4 are present at position Q). It is configured as follows. Further, at that position, a window 43a which is a blank area in which the electrode patterns M1, M2,... Are not formed is provided. That is, at the same position Q in the sliding direction in the fader portion 43, both the window portion 43a which is a blank region and the plurality of electrode patterns M3 and M4 divided by the boundary portion L3 exist.

  Thus, the electrode part 45 becomes a strip | belt-shaped detection part provided continuously along the slide direction. That is, it is possible to acquire position information (position information in the slide direction) of a finger that approaches or contacts with this detection unit based on the principle of electrostatic induction. Details of this detection principle and detection circuit will be described later.

  The cover sheet 42 is formed of a synthetic resin material of a thin plate film and is formed of a black material. The cover sheet 42 does not transmit light having a short wavelength, and the red light emitting LED element 23 that emits long wavelength light below the window 43a emits light. Light is transmitted to the upper surface side.

  As shown in FIG. 5B, the fader operation element 40 including the above-described components includes an elastic holding body 46 and a light guide on the LED element 23 mounted on the circuit board (first circuit board) 20. The fader board 41 is supported separately from the circuit board 20 via the body 47.

  The fader substrate 41 is assembled in advance by attaching the elastic holding body 46 and the light guide 47 to the lower surface side and attaching the cover sheet 42 to the upper surface side. In this state, the female connection terminal 41c provided on the lower surface 41b of the fader board 41 shown in FIG. 4B and the male connection terminal 27 provided on the upper surface of the circuit board 20 shown in FIG. A small protrusion 47c for fitting formed on the lower surface of the light guide 47 shown in FIG. 4B is press-fitted and fixed in a fitting hole (not shown) provided on the upper surface of the circuit board 20. Thereby, the fader board 41 is fixed on the circuit board 20.

  FIG. 6 is a block diagram showing a schematic configuration of an operation detection circuit (position information acquisition means) for detecting an operation on the fader operation element 40 described above. The detection of an operation (operation position) on the fader operation element 40 will be described with reference to FIG. The operation detection circuit 80 shown in the figure includes an oscillator 81 in which the oscillation frequency f is set to a constant value (for example, a fixed value such as 250 kHz, 400 kHz, etc.). , Simply referred to as “finger”.) The signal level extraction amount of the oscillator 81 is adjusted according to the relative distance between the finger and the electrode pattern Mi when the finger is approached. Thus, the operation position (touch position) in the sliding direction of the fader unit 43 is detected.

  That is, in the block diagram of the operation detection circuit 80 shown in FIG. 6, the oscillator 81 is an oscillator that generates a constant frequency, and the output of the oscillator 81 is an operation detection corresponding to each of the electrode patterns M1 to M6 of the electrode unit 45. Are input to the sections 90-1 to 90-6. Here, since the configurations of the operation detection units 90-1 to 90-6 corresponding to the electrode patterns M1 to M6 are common to each other, the following description and illustration of the operation detection unit 90-1 corresponding to the electrode pattern M1 will be given. The illustration and description of the other operation detection units 90-2 to 90-6 are omitted.

  The output of the oscillator 81 input to the operation detection unit 90-1 is input to the touch detection circuit 82. The touch detection circuit 82 inputs the input output V0 of the oscillator 81 to the two delay circuits 82a and 82b. One delay circuit 82a is an RC integration circuit including a resistor R1, an electrode pattern M1, and a capacitance (capacitor capacitance) C1 of a finger of a person who operates the electrode pattern M1, and the other delay circuit 82a includes a resistor R1. This is an RC integration circuit composed of R2 and a capacitor C2. The delay circuit 82a outputs a waveform output V1 obtained by giving a delay proportional to the product of the resistance value R1 and the capacitor capacitance C1 to the rectangular wave of the input output V0, and the delay circuit 82b outputs the input output V0. An output V2 having a waveform in which a delay proportional to the product of the resistance value R2 and the capacitor capacitance C2 is given to the rectangular wave is output. That is, the delay circuit 82a outputs a waveform with a larger delay as the finger approaches the electrode pattern M1 and the capacitor capacitance C1 increases. The output V1 of the delay circuit 82a and the output V2 of the delay circuit 82b are input to an EXOR circuit (exclusive OR) 82c. The EXOR circuit 82c outputs a waveform output V3 representing the phase difference between the waveform input from the delay circuit 82a and the waveform input from the delay circuit 82b. As described above, the output of the oscillator 81 is input to two different types of integration circuits 82a and 82b, the degrees of delay of the two signals output from the two types of integration circuits 82a and 82b are compared, and the difference between them is compared. By extracting the signal, it is possible to extract a signal (PWM signal) having a duty ratio corresponding to the degree of approach or contact of the finger to the electrode pattern M1. Then, the signal output from the EXOR circuit 82c is input to the level detection circuit 85 including an integration circuit and converted into a level value. Thereby, the output value of the level according to the approach degree of the finger | toe with respect to the electrode pattern M1 can be obtained. That is, as the ratio of the high level state increases, the output level of the level detection circuit 85 is increased.

  In this way, in the operation detection units 90-1 to 90-6, the output level value of the level detection circuit 85 is output as a different value depending on the position of the finger in the longitudinal direction of the fader unit 43. For example, as an easy-to-understand example, if the maximum value is 100 and the finger is at the Q position in FIG. 5A, the output value from the electrode pattern M3 is 98, and the output value from the electrode pattern M2 is 5 , Each output value from the electrode pattern M4 is 45. This example is for explaining the tendency of the output value of the electrode pattern Mi, and is not an actually measured value. The relative position of the finger with respect to each of the electrode patterns M1 to M6 is detected based on the level of the output value as described above. Furthermore, the output values output from the six operation detection units 90-1 to 90-6 corresponding to the six electrode patterns M1 to M6 are input to the weighted average value calculation unit (weighted average calculation means) 87, The weighted average value calculation unit 87 calculates a weighted average value of output values corresponding to the electrode patterns M1 to M6. Based on the calculated weighted average value, the position of the finger (the position in the sliding direction) with respect to the electrode unit 45 of the fader operation element 40 is acquired. The procedure for calculating the weighted average value in the weighted average value calculating unit 87 is as follows.

The weighted average value P of the output values of the six electrode patterns M1 to M6 can be calculated by the following equation (1).
P = (0 * m1 + 1 * m2 + 2 * m3 + 3 * m4 + 4 * m5 + 5 * m6) / (m1 + m2 + m3 + m4 + m5 + m6) (Formula 1)
Here, m1 to m6 are output values of the electrode patterns M1 to M6.

Subsequently, a value PP obtained by dividing the weighted average value P calculated by the above equation (1) by the predetermined value S is calculated by the following equation (2). Here, the predetermined value S is a value such that PPMAX, which is a value obtained by dividing the maximum value PMAX of P, is 128. PP is any value (integer value) from 1 to 128.
PP = P / S (Formula 2)
As a specific example of the PP value, the maximum value PMAX of P in the equation (1) can be set to a value of about “10000 to 100000”, and the minimum value PMIN can be set to “0”. .

  The value PP calculated by the equation (2) is acquired as position data (MIDI data) of the operation position in the sliding direction of the fader unit 43.

Here, let's calculate by putting numerical values in the above equations. As an easy-to-understand example, the above values are substituted into (Equation 1).
P = (0 + 5 + 196 + 135 + 0 + 0) / (0 + 5 + 98 + 45 + 0 + 0) = 336 / 148≈2.27
That is, when the center of the finger is at the Q position in FIG. 5A, P = 2.27 is output.
Further, when there is a finger contact such that the maximum value PMAX of P is obtained, that is, when the finger contacts the position corresponding to only the electrode pattern M6 (the right end of the electrode unit 45),
P = (0 + 0 + 0 + 0 + 0 + 500) / (0 + 0 + 0 + 0 + 0 + 100) = 5
It becomes. Therefore, P can take a value in the range of 0-5. As described above, the relative position of the finger in the sliding direction of the electrode portion 45 of the fader operator 40 can be accurately detected.

  Note that due to the configuration of the fader unit 43 as shown in FIG. 5A, the finger is brought into contact so that the maximum value PMAX of P = 5 (that is, the value is detected only by the electrode pattern M6). ) Is difficult, the maximum value PMAX of P is, for example, about 4.5 to 4.99. Even in such a case, since the maximum value of P may be 5, the maximum value of P must be set to 5. However, in that case, a correction process in which an appropriate P value (for example, P = 4.6) in a state where the finger is in contact with the right end of the electrode unit 45 is regarded as the maximum value PMAX of P is described in step ST2 of FIG. -3 and step ST2-4, the process of step ST2-4 may be performed with the P value after performing the correction process.

  FIG. 7 is a flowchart showing a procedure of an operation detection process for the fader operator 40. In the operation detection process for the fader operation element 40 shown in the figure, it is first determined whether or not the processing mode of the music data input device 1 is an input mode that can accept an operation for the fader operation element 40 (step ST2-). 1). As a result, if it is not the input mode (NO), the subsequent processing does not proceed. On the other hand, if the mode is the input mode (YES), the output values of the electrode patterns M1 to M6 of the fader operator 40 (the output values of the corresponding operation detection units 90-1 to 90-6) are set in advance. It is determined whether or not the predetermined threshold value is exceeded (step ST2-2). As a result, if the output values corresponding to all the electrode patterns M1 to M6 are less than the threshold value (NO), the subsequent processing does not proceed. On the other hand, if the output value corresponding to any one of the electrode patterns M1 to M6 is equal to or greater than the threshold (YES), the weighted average value P of the output values corresponding to the six electrode patterns M1 to M6 is expressed by the above equation (1). Calculate (step ST2-3).

  Subsequently, a value PP obtained by dividing the weighted average value P calculated by the equation (1) by the predetermined value S is calculated by the above equation (2). (Step ST2-4). Then, the value PP calculated by the equation (2) is taken into a storage device (such as RAM 103 described later) as position data (MIDI data) of the operation position in the sliding direction of the fader unit 43 (step ST2-5).

  When the operation on the fader unit 43 is performed, the operation position is gradually changed as the finger slides along the sliding direction of the fader unit 43. Therefore, the calculation of the operation position information according to the above procedure is repeated. The operation position is continuously detected. Further, when a slide operation on the fader unit 43 is detected, each LED element 23 of the display unit 48 is turned on based on the detected operation position, thereby displaying the position of the operation position.

  As described above, the fader operation element 40 included in the music data input device 1 according to the present embodiment is a touch-sensitive fader that detects an operation position that is operated when a finger that is a part of the body approaches or contacts. Unit 43, an operation detection circuit (position information acquisition means) 80 for acquiring the position information based on the detection of the operation position by the fader unit 43, and a display for displaying the position of the operation position with respect to the fader unit 43 Part 48. The fader unit 43 is a belt having a predetermined width with the sliding direction in which a part of the body slides along the surface as a longitudinal direction, and the display unit 48 slides in the center in the width direction of the fader unit 43. And a plurality of light-transmitting windows 43a and 43a arranged along the LED 43, and LED elements (light emitters) 23 disposed below and facing each of the windows 43a.

  According to the fader operation element 40 as described above, since the display unit 48 as a level meter is provided in the fader unit 43 (sensor area), it is possible to intuitively understand the operational feeling with respect to the fader unit 43 and the position display of the display unit 48. It is possible to make them coincide. In addition, since the display unit 48 is provided inside the fader unit 43, the installation area in the width direction of the fader operation element 40 is reduced as compared with the conventional configuration in which the display unit is provided on the side portion with respect to the sliding direction of the fader unit. It can be kept small.

  Further, the fader operation element 40 of the present embodiment includes an electrode unit 45 for detecting an operation position, and the operation detection circuit 80 operates based on a change in electrostatic capacitance between the finger and the electrode unit 45. The operation detection unit (circuit) 90 for acquiring the above is provided, and a capacitance type detection means is configured by these.

  Since the above-mentioned capacitance type detection means does not have a mechanical structure portion that is displaced with the operation of a finger, it is longer than the detection means having a mechanical structure portion such as a switch or a contact pattern. The durability against use and repeated use can be increased. Therefore, the probability that a failure such as a failure occurs in the fader operation element 40 can be kept low, and the labor of maintenance can be reduced.

  Further, the fader operation element 40 of the present embodiment extends in a direction in which the boundary portion Li is inclined with respect to the sliding direction, so that a plurality of electrode patterns Mi exist at the same position in the sliding direction in the fader portion 43. It was way. Thereby, even if the window 43a is provided in the center in the width direction of the fader 43, the detected value of the operation position by each electrode pattern Mi is output as a value (intermittent value) that increases / decreases (changes) stepwise. Without being output as a continuous value that smoothly increases and decreases. Therefore, the operation position can be accurately detected by the fader unit 43. In other words, in the present embodiment, the boundary portion Li between the adjacent electrode patterns Mi and Mi is inclined with respect to the sliding direction. For example, one finger is slid along the longitudinal direction of the fader portion 43. Even in such a case, the operation position by the one finger can be sensed simultaneously by the plurality of electrode patterns Mi, and the output of each electrode pattern Mi is output as a value corresponding to the weight (the degree of approach of the finger to the electrode pattern Mi). The Based on the output value, it is determined how much deviation output is produced by the other electrode pattern Mi adjacent to the electrode pattern Mi having the maximum output. The combined output is a value that changes smoothly (linearly) instead of being stepped. Therefore, an accurate operation position with respect to the sliding direction of the fader unit 43 can be obtained. On the other hand, for example, in the switch type detection means described in Patent Documents 3 and 4, since both the input and output of the detection value are stepped values, a continuous output value is obtained and accurate. Position detection cannot be performed.

  Further, in the fader operation element 40 of the present embodiment, even if the window portion 43 a is provided in the center in the width direction of the fader portion 43, a plurality of boundary portions Li are arranged at the same position in the sliding direction of the fader portion 43. Therefore, it is possible to more effectively prevent the output value of the electrode pattern Mi from becoming an intermittent value (a value that increases or decreases in a step function). As a result, the fader operator 40 can obtain an output value that changes more smoothly.

  The fader board 41 is a separate member from the circuit board 20 and is fixedly installed on the circuit board 20. The LED element 23 is mounted at a position corresponding to each window 43a on the circuit board 20. As a result, the fader board 41 provided with the electrode part 45 and the window part 43a, which are constituent elements of the fader operation element 40, the circuit board 20 and the LED element 23 mounted thereon are manufactured in separate processes in advance. By installing the fader board 41 on the circuit board 20, it is possible to easily assemble the fader operation element 40 having the display part 48 inside the fader part 43. Thereby, it is possible to improve the efficiency of the manufacturing process of the electronic component provided with the fader operation element 40. In addition, since it is possible to inspect the components of the fader operator 40 manufactured in a separate process and the circuit board 20 in advance, and to assemble the parts without problems, the final assembly can be obtained. The yield of the electronic component provided with 40 can be improved.

  Further, the fader operation element 40 of the present embodiment includes a support member including an elastic holding body 46 and a light guide 47 for supporting the fader board 41 above the LED elements 23 on the circuit board 20. And the light guide 47 which comprises the support member is provided with the function as a light guide member for guide | inducing the light emission of the LED element 23 to the window part 43a.

  According to this configuration, the supporting member for supporting the fader portion 43 on the circuit board 20 and the light guide member for guiding the light emission of the LED element 43 to the window portion 43a of the fader portion 43 can be combined into one component. As a result, the number of parts of the fader operation element 40 can be reduced accordingly.

  The music data input device (operator device) 1 of the present embodiment includes a fader operator 40 having the above-described configuration, a switch contact pattern 21 formed on the circuit board 20, and a switch contact pattern 21. A switch operator 30 having a plurality of switches 30a each composed of a key top portion (operation part) 33 arranged opposite to each other, and an upper case that is placed on top of the lower case 15 and the lower case 15 11 is provided. The fader operator 40 and the switch operator 30 on the circuit board 20 are accommodated between the lower case 15 and the upper case 11 of the outer case 10. Further, a plurality of LED elements 23 provided on the circuit board 20 are arranged side by side, and the fader portion 43 has a longitudinal direction along the arrangement direction of the LED elements 23 (second LED elements 23b) on the circuit board 20. As shown in FIG.

  In the music data input device (operator device) 1 according to the present embodiment, the upper case 11 includes a frame (first upper case) 12 whose edge 12a overlaps the edge 15a of the lower case 15, and the frame. And a panel plate (second upper case) 13 which is attached to the inside of the body 12 and has openings 13f and 13g for exposing the fader operation element 40 and the switch operation element 30 to the outside of the exterior case 10. ing.

  According to this configuration, it is possible to configure an exterior case that can be used for a plurality of types of music data input devices having different shapes and arrangement configurations on the circuit board 20 simply by changing the shape of the panel board 13. As a result, a plurality of types of music data input devices can be configured by changing the specifications of only the panel board 13 and the switch operator 30 with the lower case 15 and the frame body 12 and the circuit board 20 as common specifications. . Therefore, it is possible to manufacture a variety of music data input devices with a small number of parts.

  In addition, the music data input device 1 of the present embodiment includes a first LED element 23 a provided on the circuit board 20 installed in the case 11, and a switch contact pattern 21 formed around the first LED element 23 a on the circuit board 20. A switch operator 30 having a plurality of switches 30a each including a first LED element 23a and a key top portion (operation part) 33 disposed to face the switch contact pattern 21, and provided on the circuit board 20. The plurality of second LED elements 23 b, the light guide body 47 having a plurality of through holes or light transmitting portions disposed corresponding to the plurality of second LED elements 23 b, and the circuit board 20 via the light guide body 47. Fader board 41 installed on top, touch-sensitive fader section 43 provided on fader board 41, and through holes or holes of light guide 47 in fader section 43. And a fader operator 40 composed of a window portion 43a provided at positions corresponding to the transparent portion. Then, at least one of the plurality of second LED elements 23b included in the fader operation element 40 is provided with the switch contact pattern 21 around the second LED element 23b so that the switch operation element 30 has the same configuration as the first LED element 23a. It can also be used as the first LED element 23a provided.

  As a result, the music data input device 1 of the present embodiment having both the fader operation element 40 and the switch operation element 30 on one type of circuit board 20, and a second embodiment to be described later provided with only the switch operation element 30. It is possible to configure a circuit board that can be used for both of the music data input device 1-2. Therefore, by using a common circuit board in a plurality of types of music data input devices, it is possible to reduce the types of components and increase the manufacturing efficiency of the product.

  Further, according to the fader operation element 40 of the present embodiment, when the finger moving along the sliding direction of the fader portion 43 comes in contact with the plurality of electrode patterns Mi at the same time when straddling the window portion 43a, the operation is performed. The detection value for detecting the position does not have to be an intermittent value. That is, even if a blank area where the electrode pattern Mi is not formed is provided in a part of the electrode part 45 of the fader part 43, information on the operation position by the finger is obtained by the plurality of electrode patterns Mi provided at the same position as the blank area. It can be obtained as a smooth continuous value.

  Further, in the present embodiment, the blank area where the electrode pattern Mi provided in the fader portion 43 is not formed is a window portion 43 a made of an opening formed in the fader substrate 41, and the window portion 43 a is formed of the LED element 23. Although the case where the light emission is a part of the display unit 48 for guiding the light emission to the fader unit 43 is shown, the blank area of the fader unit according to the present invention is not limited to the above-described configuration, but other configurations. May be. As an example, although detailed illustration is omitted, as a blank area of the fader part, a switch part including a window part provided in the fader substrate and a membrane type switch arranged in the window part can be arranged. . The membrane type switch here is two flexible boards (flexible boards) installed at predetermined intervals via spacers at positions corresponding to the windows, and the opposing surfaces of the two flexible boards It can be set as the structure which has a pair of contact pattern formed in this. In this case, when the finger operating the fader operation element along the sliding direction passes through the position of the window portion, the switch can be configured to be turned on when the finger contacts the membrane switch. The membrane-type switch can be assigned a function for locking the slide operation on the fader operator at that position. Furthermore, the switch provided in the window provided on the fader substrate is not limited to the membrane type switch described above, and may be a switch having another configuration such as a push button type switch.

  Further, in the music data input device 1 of the present embodiment, in addition to the plurality of electrode patterns Mi divided by the boundary portion Li existing at the same position in the sliding direction of the fader portion 43, each electrode pattern Mi By acquiring the operation position of the fader unit 43 based on the weighted average value of the capacitance detected in step 1, the operation position (operation position in the slide direction) with respect to the fader unit 43 can be acquired with high accuracy. It becomes possible.

  That is, in the fader operation element 40 provided in the music data input device 1 of the present embodiment, each of the plurality of electrode patterns M1 to M6 provided in the fader unit 43 and each of the fingers that are close to or in contact with them are formed. The weighted average value of the capacitance is calculated, and the operation position information (touch position information) in the sliding direction of the fader operation element 40 is obtained using the weighted average value.

  Here, a preferred usage mode of the fader operator 40 will be briefly described. For example, the fader operation element 40 of this embodiment can be used as an operation element for performing volume control of the total volume in the mixer apparatus. In this case, in the case of real-time control, the calculated value PP is taken into the storage device, and at the same time, output control is performed as the sound source volume. If not real-time control, the calculated value PP is output to the sound source without taking it into the storage device. The fader operation element 40 can be used as an operation element for performing a slide operation during creation of music data. In this case, for example, in the case of the edit mode after recording using three channels such as vocal, guitar, and keyboard, the above calculation is performed if the operation of the fader operator 40 is used to adjust the volume of the vocal channel. The value PP is recaptured in the storage device together with the recording data (time data) so that the volume of the vocal channel increases or decreases. In particular, when processing such as fade-in / fade-out of a vocal channel is performed after recording, it is convenient to perform volume adjustment using the fader operator 40 of the music data input device 1 of the present embodiment.

  Next, the configuration of the control circuit included in the music data input device 1 will be described. FIG. 8 is a block diagram showing the configuration of the control circuit of the music data input device 1. As shown in the figure, the music data input device 1 is controlled by a microcomputer comprising a microprocessor unit (CPU) 101, a read only memory (ROM) 102, and a random access memory (RAM) 103.
