[0027] Below, refer to Figures 1 to 15 One embodiment of the present invention will be described.

[0028] The processing device of this embodiment performs signal processing on the input sound signal (signal related to sound) and then inputs the signal to an external sound processing device. Figure 1 As shown, the processing device 1 has a touch panel 2 and a plurality of physical operating elements 3 , 4 .

[0029] The touch panel 2 has a display surface 2a for displaying various information. The touch panel 2 detects changes in capacitance associated with user operations. The capacitance detected by the touch panel 2 is the capacitance between the display surface 2a of the touch panel 2 and the user's finger. In the touch panel 2, the relative positional relationship between the display surface 2a and the user's finger changes when the user's finger approaches the display surface 2a, thereby changing the detected capacitance.

[0030] The display surface 2a of the touch panel 2 has a first area 2a1 where the first physical operating member 3 described later is configured, and a second area 2a2 where the first physical operating member 3 is not configured. The mechanism for detecting capacitance in the touch panel 2 is the same in the first area 2a1 and the second area 2a2. However, the sensitivity of detecting capacitance in the first area 2a1 is higher than the sensitivity of detecting capacitance in the second area 2a2. The second area 2a2 mainly detects the contact of the user's finger to the second area 2a2 based on the change in capacitance.

[0031] In the first area 2a1, the capacitance is detected in multiple stages. That is, in the first area 2a1, not only whether the user's finger is in contact with the display surface 2a is detected, but also the distance between the display unit 117 and the user's finger is detected in multiple stages.

[0032] The physical operating elements 3 and 4 are operated by the user. The physical operating elements 3 and 4 include a first physical operating element 3 disposed on the display surface 2a and a second physical operating element 4 provided outside the display surface 2a.

[0033] The first physical operator 3 changes the capacitance detected by the touch panel 2 when operated by the user. The first physical operator 3 includes a push switch 10 that can be pressed and an encoder 20 that can be rotated (hereinafter referred to as a first encoder 20).

[0034] like Figure 2 As shown, the push switch 10 includes a key top 11, a support portion 12 placed on a display surface 2a, and a connection portion 13 connecting the key top 11 and the support portion 12. The connection portion 13 holds the key top 11 in a manner that the key top 11 is spaced apart from the display surface 2a when the support portion 12 is placed on the display surface 2a. In addition, the connection portion 13 elastically deforms when the key top 11 is pressed by a user's finger and moves toward the display surface 2a. The user's pressing operation on the push switch 10 is performed by the user pressing the key top 11 toward the display surface 2a with his or her finger. The user releases the pressing of the key top 11, and the key top 11 returns to its original position due to the elastic force of the connection portion 13.

[0035] When the user presses the push switch 10 with his finger, the user's finger contacts the same side as the display surface 2a (at Figure 2 The top surface 11a of the key top 11 is recessed in a concave shape. In addition, the top surface 11a of the key top 11 may be bulged in a convex shape, or may be formed flat, for example.

[0036] The first area 2a1 of the touch panel 2 described above detects the contact of the user's finger with the top surface 11a of the push switch 10 and the pressing of the push switch 10 based on the change in capacitance. For example, if the user's finger contacts the top surface 11a of the key top 11, the capacitance detected in the first area 2a1 changes. In addition, if the user's finger presses the key top 11 toward the display surface 2a from the state of contact with the top surface 11a of the key top 11, the finger approaches the display surface 2a, so the capacitance detected in the first area 2a1 further changes. That is, the first area 2a1 of the touch panel 2 detects the state of the user's finger contacting the key top 11 and the state of the key top 11 being pressed in separately. In addition, the first area 2a1 of the touch panel 2 can also detect, for example, the position where the key top 11 is pressed halfway and the position where the key top 11 is fully pressed in separately. That is, the first area 2a1 of the touch panel 2 can detect the change in the amount of pressing of the key top 11 in multiple stages.

[0037] In the push switch 10 of the present embodiment, the key top 11 is configured as a light-transmitting portion that transmits light. The key top 11 that functions as a light-transmitting portion transmits light without scattering. Therefore, information such as characters, symbols, patterns, and images displayed on the display surface 2a (for example, Fig. 9 , 10 The icons 501 and 502 shown in the figure can be visually confirmed through the key top 11. In the present embodiment, the support portion 12 and the connecting portion 13 of the push switch 10 are formed in an opaque manner so that light does not pass through. In addition, the support portion 12 and the connecting portion 13 can, for example, allow light to pass through while scattering, or can, for example, allow light to pass through without scattering like the key top 11.

[0038] like Figure 3 As shown, the first encoder 20 includes a fixed portion 21 fixed to the display surface 2a of the touch panel 2, a rotation operation portion 22 that can be rotated relative to the fixed portion 21 by a user's finger, and a bearing 23 provided between the fixed portion 21 and the rotation operation portion 22. By interposing the bearing 23 between the fixed portion 21 and the rotation operation portion 22, the rotation operation portion 22 can be smoothly rotated relative to the fixed portion 21. The rotation operation portion 22 is arranged at a distance relative to the display surface 2a. Preferably, the distance between the rotation operation portion 22 and the display surface 2a is small. In addition, the rotation operation portion 22 can be in contact with the display surface 2a, for example.

[0039] In the first encoder 20 of the present embodiment, the rotation operation part 22 is formed into a cylindrical shape. In addition, the first encoder 20 also has a pressing operation part 25 (inner part) arranged inside the rotation operation part 22. The pressing operation part 25 is pressed by the user's finger in the same manner as the above-mentioned push switch 10. That is, the pressing operation part 25 has a key top 26 and a connecting part 27 connecting the key top 26 and the rotation operation part 22. The connecting part 27 holds the key top 26 in a manner that the key top 26 is arranged at a distance from the display surface 2a. In addition, the connecting part 27 elastically deforms when the key top 26 is pressed by the user's finger and moves toward the display surface 2a. The user's pressing operation on the pressing operation part 25 is performed by the user pressing the key top 26 toward the display surface 2a with his finger. By releasing the user's pressing of the key top 26, the key top 26 is restored to its original position by the elastic force of the connecting part 27.

[0040] The first area 2a1 of the touch panel 2 provided with the first encoder 20 detects the user's rotation operation of the first encoder 20 based on the change in capacitance. For example, if the user rotates the rotation operation unit 22 while the user's finger is in contact with the rotation operation unit 22, the position of the user's finger in contact with the rotation operation unit 22 moves, and thus the capacitance detected in the first area 2a1 changes.

[0041] The first region 2a1 detects contact of the user's finger with the first encoder 20 based on a change in capacitance. Specifically, when the user's finger contacts the rotation operation unit 22 or the pressing operation unit 25 of the first encoder 20, the capacitance detected in the first region 2a1 changes.

[0042] Furthermore, the first region 2a1 detects the user's finger pressing the push operation portion 25 based on the change in capacitance. Specifically, when the user's finger presses the key top 26 toward the display surface 2a, the finger approaches the display surface 2a, and the capacitance detected in the first region 2a1 changes.

[0043] In the first encoder 20, the above three types of capacitance change in different ways. Therefore, the first area 2a1 of the touch panel 2 detects the rotation operation of the rotation operation unit 22, the contact of the user's finger to the first encoder 20, and the pressing operation of the pressing operation unit 25 separately. In addition, the first area 2a1 of the touch panel 2 can detect the change in the pressing amount of the key top 26 of the pressing operation unit 25 in multiple stages.

[0044] In the first encoder 20 of the present embodiment, the key top 26 of the pressing operation unit 25 is configured as a light-transmitting unit that transmits light. The key top 26 that functions as a light-transmitting unit transmits light without scattering. Therefore, the information such as characters, symbols, patterns, and images displayed on the display surface 2a is not limited to the color and light displayed on the display surface 2a. Fig. 9 , 10 The icons 501 and 502 shown in the figure can also be visually confirmed through the key top 26. In the present embodiment, the rotation operation part 22 and the fixed part 21 of the first encoder 20 are formed in an opaque manner so that light does not pass through. In addition, the rotation operation part 22 can, for example, allow light to pass through while scattering, or can, for example, allow light to pass through without scattering like the key top 26.

[0045] like Figure 1 As shown, the processing device 1 of this embodiment has a plurality of the above-mentioned push switches 10 (in Figure 1 Specifically, the plurality of key tops 11 are connected by a support portion 12 (see Figure 2 ) and link.

[0046] like Figures 1 to 3 As shown in FIG. 1 , the processing device 1 of the present embodiment further includes a support 5. The support 5 is formed in a plate shape and is arranged to overlap with the first area 2a1 of the display surface 2a.

[0047] The support body 5 integrally supports the plurality of first physical operating members 3 (a plurality of push switches 10, a first encoder 20). Specifically, the support body 5 is fixed to a surface of the support portion 12 that connects the key tops 11 of the plurality of push switches 10, which faces the opposite side to the display surface 2a. In addition, the support body 5 is integrally formed with the fixing portion 21 of the first encoder 20.

[0048] The support body 5 has a plurality of first through holes 51 and second through holes 52 extending in the thickness direction thereof. The key tops 11 of the push switches 10 are inserted into the first through holes 51. The rotational operation portion 22 and the push operation portion 25 of the first encoder 20 are inserted into the second through holes 52.

[0049] The support body 5 is formed in an opaque manner so that light does not pass through. Therefore, various information displayed in the first area 2a1 of the display surface 2a can only be visually confirmed through the first and second through holes 51, 52 of the support body 5, and the key top 11 of the push switch 10 and the key top 26 of the push operation portion 25 inserted therein.

[0050] The support 5 is fixed to the touch panel 2 in a state of being arranged overlapping the first area 2a1 of the display surface 2a. The support 5 is detachable from the touch panel 2. Thus, the first physical operation element 3 is detachable from the display surface 2a of the touch panel 2.

[0051] like Figure 1 As shown, as the second physical operating element 4 of this embodiment, there are an encoder 41 (hereinafter referred to as a second encoder 41) that can be rotationally operated and a fader 42 that can be linearly moved.

[0052] For processing device 1, Figure 1 The lower part of the processing device 1 is located on the side close to the user, and the upper part of the processing device 1 is located on the side away from the user. That is, Figure 1 The up and down direction corresponds to the up and down direction observed from the user. Figure 1 The left and right directions correspond to the left and right directions as viewed from the user. Figure 1 The configuration of the first physical operation element 3 and the second physical operation element 4 will be described with reference to the up-down direction and the left-right direction.

[0053] A plurality of push switches 10 and a first encoder 20 are arranged on the first area 2a1 of the touch panel 2 adjacent to the lower side of the second area 2a2 of the touch panel 2. The push switches 10 are arranged in a plurality in the left-right direction along the lower end of the second area 2a2 of the touch panel 2 (in the left-right direction). Figure 1 In the example, 8 push switches 10 are arranged in the left-right direction. The number of push switches 10 arranged in the left-right direction corresponds to the number of specified channels (for example, the number of input ch 1120 and output ch 1140 described later). In addition, there are 2 push switches 10 arranged in the upper-lower direction in the group of 8 push switches 10 arranged in the left-right direction. One first encoder 20 is arranged on the right side of the 8 push switches 10.

[0054] The plurality of second encoders 41 and the plurality of sliders 42 are arranged on the lower side of the first area 2a1 of the touch panel 2, specifically, on the lower side of the plurality of push switches 10. The plurality of second encoders 41 and the plurality of sliders 42 are arranged at intervals in the left-right direction in the same manner as the push switches 10 (in the left-right direction). Figure 1 The number of the second encoders 41 and the faders 42 arranged in the left-right direction corresponds to the number of channels specified. Each fader 42 is located below the second encoder 41 and is configured to be able to perform linear movement in the up-down direction.

[0055] Two push switches 10, one second encoder 41, and one fader 42 arranged in order from top to bottom constitute one channel strip. In addition, in the processing device 1, eight channel strips are arranged in the left-right direction. The push switch 10 among the first physical operating elements 3 functions as an individual corresponding operating element corresponding to each channel. On the other hand, the first encoder 20 among the first physical operating elements 3 functions as a collective corresponding operating element corresponding to a plurality of channels.

[0056] like Figure 4 As shown, the processing device 1 is a digital mixer, and has a CPU 111, a ROM 112, a RAM 113, a display I / F 114, a detection I / F 115, a communication I / F 116, a DSP (Digital Signal Processor) 120, and an effector 121, which are connected via a communication bus 125. In addition, a display unit 117 is connected to the display I / F 114, an operating element 118 is connected to the detection I / F 115, and a communication input and output unit (I / O) 119 is connected to the communication I / F 116. Furthermore, the processing device 1 also has an AD conversion unit 122, a DA conversion unit 123, and a DD conversion unit 124, which are connected to the DSP 120 and the effector 121 via a voice bus 126.

[0057] The CPU 111 performs overall control of the operation of the processing device 1. The CPU 111 executes a predetermined program stored in the ROM 112 to perform processing such as controlling the display of the display unit 117 via the I / Fs 114 to 116, detecting the operation of the operating element 118, and communication via the communication I / O 119, or controlling signal processing of the DSP 120.

[0058] The ROM 112 is a rewritable nonvolatile storage unit that stores a control program and the like executed by the CPU 111. As the ROM 112, a flash memory and the like can be used.

[0059] The RAM 113 is a storage unit for storing parameter values ​​reflected in the signal processing of the DSP 120 or used as a work memory of the CPU 111 .

[0060] The display I / F 114 is an interface for connecting the display unit 117 to the communication bus 125 and controlling the display content thereof according to the instruction from the CPU 111. The display unit 117 displays a screen showing the current state of the processing device 1, a screen for referring to, changing, saving, etc. of parameters used in signal processing, etc. The display unit 117 corresponds to the function of displaying various information in the aforementioned touch panel 2 on the display surface 2a.

[0061] The detection I / F 115 is an interface for connecting the operating element 118 to the communication bus 125 and detecting the operation content thereof according to the instruction from the CPU 111. The operating element 118 is an operating element 118 for the user to directly operate the processing device 1 to edit parameters, etc. The operating element 118 corresponds to the aforementioned first physical operating element 3 (push switch 10, first encoder 20), the second physical operating element 4 (second encoder 41, fader 42), and the function of detecting the change in capacitance in the touch panel 2.

[0062] Communication I / F 116 is an interface for connecting communication I / O 119 to communication bus 125 and controlling data transmission and reception via communication I / O 119 according to instructions from CPU 111. Communication I / O 119 can communicate with external devices via a network or by peer-to-peer communication.

[0063] The DSP 120 is a signal processing unit including a signal processing circuit, and performs signal processing according to the value of a parameter set in the signal processing on the input sound signal. The effector 121 has a function of applying various effects such as reverberation and chorus to the input sound signal and outputting the result.

[0064] The AD converter 122 has a function of converting analog sound signals input from a plurality of input terminals into digital waveform data and supplying the digital waveform data to the audio bus 126. The DA converter 123 has a function of converting digital waveform data of a plurality of ch (a plurality of channels) obtained from the audio bus 126 into analog sound signals and outputting the digital waveform data from output terminals associated with the waveform data. The DD converter 124 has a function of performing format conversion required for inputting and outputting digital waveform data between the audio bus 126 and the terminals.

[0065] The audio bus 126 can transmit multiple channels of digital waveform data in a time-division manner, and each channel functions as a signal transmission path for transmitting a signal from the output of any processor (including the effector 121) or conversion unit connected to the audio bus 126 to the input of another processor or conversion unit.

[0066] Next, refer to Figures 5 to 8 , which is expressed in more detail in Figure 4 The structure of the signal processing performed in the DSP 120 is shown.

[0067] like Figure 5 As shown, the signal processing in the DSP 120 has an input patch 1110 , an input ch (channel) 1120 , a mixing bus 1130 , an output ch 1140 , a prompt bus 1150 , a prompt output ch 1160 , and an output patch 1170 .

[0068] In the DSP 120 , the input connector 1110 can connect (wire) any one of the input ports prepared in a manner corresponding to the input terminals of the AD converter 122 or the DD converter 124 to each of the N input channels 1120 from the first ( 1120 - 1 ) to the Nth ( 1120 - N ).

[0069] like Figure 6 As shown, each input channel 1120 includes a signal processing unit that performs signal processing on an audio signal input from an input port connected via the input connector 1110 . Figure 6 The input channel 1120 shown has a head amplifier (HA) 1121, a high pass filter (HPF) 1122, an equalizer (EQ) 1123, a dynamics processor (Dynamics) 1124, and a level adjustment unit 1125 as a signal processing unit, which are connected in order from the input connector 1110 side. In addition, the input channel 1120 may have other signal processing units such as an attenuator, a noise gate (GATE), a compressor (COMP), a delay (DELAY), a volume controller (LEVEL), and a sound field localization (PAN).

[0070] In each input channel 1120, after the signal is processed by each signal processing unit, the processed signal is sent to any bus among the M-system mixing buses 1130 from the first to the Mth. In addition, the level and on / off of the output from each channel in the input channel 1120 to each bus in the mixing bus 1130 can be set individually.

[0071] In addition, input ch 1120 can be used to convert Figure 6 The sound signal taken out from any of the take-out positions P1 to P3 set in the three locations is sent as a signal for audition to the prompt bus 1150. The prompt switching switch 1126 switches the take-out positions P1 to P3. In addition, the prompt switching switch 1126 controls the contact point to select which take-out position P1 to P3 is connected to through the CPU 111.

[0072] Only the input ch 1120 selected by the user as the audition target sends a signal to the cue bus 1150. For the unselected input ch 1120, the cue switching switch 1126 selects a contact point that is not connected to any of the fetching positions P1 to P3.

[0073] like Figure 5As shown, in the mixing bus 1130 of each system, the signal input from each input ch 1120 is mixed, and the mixed signal is output to the output ch 1140 having M chs from the first (1140-1) to the Mth (1140-M) corresponding to each system.

[0074] like Figure 7 As shown, each output channel 1140 includes a signal processing unit that performs signal processing on the audio signal input from the corresponding mixing bus 1130 . Figure 7 The output ch1140 shown has an equalizer 1143, a dynamics processor 1144, and a level adjustment unit 1145 as a signal processing unit, which are connected in order from the mixing bus 1130 side. In addition, the output ch1140 may have other signal processing units such as a compressor (COMP), a volume controller (LEVEL), a balancer (BAL), a delay (DELAY), and an attenuator.

[0075] In addition, the output ch 1140 is as follows Figure 7 As shown, it is possible to Figure 7 The sound signal taken out from any of the take-out positions P4 to P6 set in the three locations is sent to the prompt bus 1150 as a signal for audition. The prompt switching switch 1146 is a switch corresponding to the prompt switching switch 1126 for switching the take-out positions P4 to P6. In addition, only the output ch 1140 selected by the user as the audition object sends the signal to the prompt bus 1150. In the output ch 1140 that is not selected, the prompt switching switch 1146 selects a contact that is not connected to any of the take-out positions P4 to P6.

[0076] In addition, as a function of the processing device 1, both the input ch 1120 and the output ch 1140 may be selected as audition objects. However, it is generally assumed that only one of the input ch 1120 and the output ch 1140 is selected as the audition object.

[0077] like Figure 5 As shown, the prompt bus 1150 mixes the signals input from each input ch 1120 and each output ch 1140, and outputs the mixed signal to the prompt output ch 1160.

[0078] like Figure 8 As shown, in the cue output ch 1160, the sound signal input from the cue bus 1150 is subjected to signal processing by the respective signal processing units of the attenuator 1161, the equalizer 1163, the dynamics processor 1164, and the level adjustment unit 1165.

[0079] The output connector 1170 connects each output channel 1140 and the prompt output channel 1160 to an output port prepared in a manner corresponding to an output terminal provided in the DA conversion unit 123 or the DD conversion unit 124, and supplies the signal processed by each output channel 1140 and the prompt output channel 1160 to the output port of the connection destination and outputs it from the output port. In addition, the connection destination of the prompt output channel 1160 is a fixed output port for monitor output.

[0080] The signal processing performed by the above-mentioned parts (input ch 1120, output ch 1140, prompt output ch 1160, etc.) of the DSP 120 can be controlled by setting the value of a specified parameter stored in the memory. In addition, the functions of the above-mentioned parts of the DSP 120 can be realized by software or hardware.

[0081] The processing device 1 of this embodiment includes a control unit that changes / adjusts processing parameters in accordance with changes in the capacitance of the touch panel 2 based on the operation of the first physical operating element 3. In addition, in the processing device 1 of this embodiment, the control unit changes / adjusts a part of the processing parameters based on the operation of the second physical operating element 4.

[0082] The "processing parameters" include contents corresponding to various signal processing units (equalizer, noise gate, compressor, etc.) of the aforementioned DSP 120 input ch 1120, output ch 1140, and prompt output ch 1160. In addition, the "processing parameters" may also include the output level of the signal output from each ch 1120, 1140, 1160 to the subsequent bus 1130, 1150 or output connector 1170, or the switching of the output of the signal on and off, the switching of various display information displayed on the display surface 2a, and the like.

[0083] The control unit changes / adjusts the processing parameters corresponding to the sound signal input to each ch. The control unit may be the CPU 111 (see Figure 4 ) is executed in the program.

[0084] As operations of the first physical operating element 3 that changes the capacitance, there are the contact and pressing of the user's finger on the aforementioned push switch 10, the rotation operation of the user's finger on the rotation operation part 22 of the first encoder 20, and the contact and pressing of the push operation part 25. In addition, as operations of the first physical operating element 3 that changes the capacitance, there is also an operation of sliding the user's finger to sequentially contact multiple first physical operating elements 3. For example, in Figure 1 In the processing device 1 shown, the user's finger is slid so as to sequentially contact a plurality of push switches 10 arranged in the left-right direction.

[0085] The control unit determines whether a sliding operation has been performed, for example, in the following manner. For example, from a state where the user's finger touches the push switch 10 at the left end among the plurality of push switches 10 arranged in the left-right direction, the push switch 10 touched by the finger changes sequentially to the right within a predetermined time, and finally the finger touches the push switch 10 at the right end, whereby the control unit determines that a sliding operation from left to right has been performed. Similarly, the control unit determines whether a sliding operation from right to left has been performed. The control unit may determine the sliding operation when the push switch 10 is pressed in.

[0086] In this embodiment, the control unit changes the processing parameters in accordance with the sliding operation. The change of the processing parameters based on the sliding operation can be, for example, switching of the display on the display surface 2a, changing of the input and output volume, switching of the ch displayed on the display surface 2a, switching of the functional layer, switching of the effect (effect) effect, etc. Here, the channel layer is cited as an example of a functional layer. The channel layer refers to a group divided according to the initial setting of at least one or more channels among all channels, or a group arbitrarily divided by the user. By switching the channel layer, the channel used to change / adjust the processing parameters can be changed using the first physical operating element 3 and the second physical operating element 4.

[0087] The change of the processing parameter performed by the control unit in response to the sliding operation may be different for the sliding operation from left to right and the sliding operation from right to left. For example, the control unit may switch to a functional layer with a larger number (e.g., a channel number) for the sliding operation from left to right, and switch to a functional layer with a smaller number (e.g., a channel number) for the sliding operation from right to left.

[0088] In the processing device 1 of the present embodiment, various icons (such as Fig. 9 , 10 The icons 501, 502 shown in the figure). The icons displayed on the display surface 2a may be characters, symbols, patterns, colors, images (still images), videos (animations), etc. The icons may be displayed, for example, in an area overlapping with the first physical operating element 3, so that they can be visually confirmed through the key tops 11, 26 (light-transmitting portions) of the first physical operating element 3. The display surface 2a displays icons associated with processing parameters for each ch. That is, multiple icons may be displayed on the display surface 2a.

[0089] In addition, on the display surface 2 a of the touch panel 2 , information related to a selected channel among the plurality of channels is displayed in response to input to the touch panel 2 accompanied by a change in capacitance.

[0090] Furthermore, the processing device 1 of the present embodiment has a function selection unit. The function selection unit selects or changes the type of processing parameter and the icon corresponding to the processing parameter in accordance with the input to the touch panel 2 accompanied by the change in capacitance. The input to the touch panel 2 accompanied by the change in capacitance can be an input via an operation to the first physical operating member 3, or a direct input to the touch panel 2 (for example, an input achieved by the user's finger contacting or approaching the display surface 2a). The selection of icons by the function selection unit can be a change in characters, symbols, patterns, colors, images (still images), images (animation), and can also include a change in the display mode of icons such as brightness.

[0091] In addition, the function selection unit of the present embodiment detects the change of capacitance in multiple stages relative to the first area 2a1 of the touch panel 2, and selects or changes the icon along with the change of capacitance in each stage. For example, the capacitance detected in the first area 2a1 changes when the user's finger contacts the key top 11 of the push switch 10, and the function selection unit changes the icon visually confirmed by the key top 11 (for example, changes it to the character "SEL"). In addition, the capacitance detected in the first area 2a1 further changes by pressing the key top 11 into the display surface 2a from the state where the user's finger contacts the key top 11, and the function selection unit further changes the icon visually confirmed by the key top 11 (for example, changes it to the character "ON").

[0092] The function selection unit may be in the aforementioned CPU 111 (refer to Figure 4 ) is executed in the program.

[0093] The first physical operating element 3 receives a user operation corresponding to the type of processing parameter selected in the above-mentioned function selection unit.

[0094] Next, the operation of the processing device 1 of this embodiment configured as described above is exemplified. Fig. 9 and Fig.10 Provide explanation.

[0095] Fig. 9 FIG. 2 shows a first display example of the display screen 2a of the processing device 1 according to the present embodiment. Fig. 9 In the first display example, a plurality of ch names 504 (channel names 504 ) and information 505 of a signal processing unit of a selected ch name 504 are displayed in the second area 2 a 2 of the display surface 2 a .

[0096] A plurality of ch names 504 are arranged in the left-right direction at the lower end of the second area 2a2, and correspond to the plurality of channel strips arranged in the left-right direction. The number of ch names 504 displayed in the second area 2a2 corresponds to the number of channel strips, which is eight.

[0097] exist Fig. 9 The displayed channel name 504 is the aforementioned plurality of input channels 1120 (refer to Figure 5 ), the user can switch to display of other ch names 504 by performing a predetermined operation on the processing device 1. For example, when the number of input ch 1120 of the processing device 1 is 16, the ch names 504 of the plurality of input ch 1120 displayed in the second area 2a2 can be switched to the first to eighth input ch 1120 (CH.1 to 8) and the ninth to sixteenth input ch 1120 (CH.9 to 16) by performing a predetermined operation on the processing device 1 by the user. The switching of the display of the ch name 504 can be performed, for example, by sliding the user's finger in a manner such that the user sequentially touches the plurality of push switches 10 arranged in the left-right direction.

[0098] The plurality of ch names 504 displayed at the lower end of the second area 2a2 may be, for example, output ch 1140 and prompt output ch 1160.

[0099] The signal processing unit information 505 is displayed above the channel name 504 in the second area 2a2. The signal processing unit information 505 is a selected input channel 1120 (in the channel name 504) among the multiple input channels 1120 displayed. Fig. 9 In the ch name 504, the selected input ch 1120 (CH.1) is different from the other input ch 1120 (CH.2 to 8) in a different manner (in Fig. 9 The selection of the input ch 1120 can be performed, for example, by the user's finger touching a predetermined input ch 1120 (for example, CH.1) among the plurality of input ch 1120 displayed in the second area 2a2.

[0100] exist Fig. 9 In FIG. 1 , as information 505 of the signal processing unit, three information of an equalizer (EQ) 505 - 1 , a noise gate (GATE) 505 - 2 , and a compressor (COMP) 505 - 3 of the selected input ch 1120 (CH. 1) are displayed.

[0101] The equalizer 505 - 1 is an equalizer that adjusts the frequency characteristics of the input sound signal. For example, the equalizer 505 - 1 can change / adjust the frequency characteristics of four frequency bands, namely, “HI”, “MIDHI”, “LOWMID”, and “LOW”.

[0102] The noise gate 505 - 2 is a noise gate for cutting off noise, and when the level of the sound signal input to the noise gate 505 - 2 becomes lower than a reference value, the gain of the input sound signal is sharply reduced to cut off the noise. The noise gate 505 - 2 can change / adjust the reference value.

[0103] The compressor 505 - 3 narrows the dynamic range of the input sound signal to prevent the input sound signal from being saturated. The compressor 505 - 3 can change / adjust the dynamic range.

[0104] In addition, the information 505 of the signal processing unit of the input ch 1120 displayed in the second area 2a2 is not limited to the above, and may be, for example, a head amplifier, a high-pass filter, a dynamic processor, a level adjustment unit, etc.

[0105] The above-mentioned parameters (equalizer 505-1, noise gate 505-2, compressor 505-3, etc.) can be changed / adjusted by, for example, the user touching the curve of each parameter displayed in the second area 2a2 and directly operating it, or by, for example, the user operating the second encoder 41, fader 42 (see Figure 1 ) is operated. In addition, the change / adjustment of each parameter can be performed by the user operating the first encoder 20, for example.

[0106] When the first encoder 20 is used, the parameter can be changed / adjusted by the user rotating the rotation operation unit 22. When the first encoder 20 is used, for example, when the user's finger does not press the push operation unit 25 or does not touch the push operation unit 25, the parameter can be roughly changed / adjusted by the user rotating the rotation operation unit 22. In addition, when the user's finger presses the push operation unit 25 or touches the push operation unit 25, the parameter can be finely changed / adjusted by the user rotating the rotation operation unit 22. When the user's finger presses the push operation unit 25 or touches the push operation unit 25, for example, an icon indicating that the parameter is finely changed / adjusted can be visually confirmed through the key top 26 of the push operation unit 25.

[0107] exist Fig. 9In the first display example, icons 501 and 502 corresponding to the plurality of push switches 10 are displayed in the first area 2a1 of the display surface 2a where the push switches 10 and the first encoder 20 are arranged. The icon 501 corresponding to the lower push switch 10 of the two push switches 10 arranged in the vertical direction includes the character "ON" and can be visually confirmed through the key top 11 of the lower push switch 10. In addition, the icon 502 corresponding to the upper push switch 10 includes the character "CUE" and can be visually confirmed through the key top 11 of the upper push switch 10.

[0108] The push switch 10 at the bottom corresponding to the icon 501 including "ON" is pressed to switch the specified input channel 1120 (for example, CH.1) displayed in the channel name 504 to the mixing bus 1130 (see Figure 5 ) is switched on and off. The prescribed lower push switch 10 and the prescribed input ch 1120 corresponding thereto are arranged in the up-down direction. In the present embodiment, the lower push switch 10 is pressed in from the off state to turn on, and then even if the pressing of the lower push switch 10 is released, the on state is maintained. In addition, the lower push switch 10 is pressed in again from the on state to turn off, and then even if the pressing of the lower push switch 10 is released, the off state is maintained.

[0109] The upper push switch 10 corresponding to the icon 502 including "CUE" is assigned to a cue switching switch 1126 (see FIG. 1 ) of a predetermined input channel 1120 (for example, CH.1) displayed in the channel name 504. Figure 6 ). The predetermined upper push switch 10 and the corresponding predetermined input channel 1120 are arranged in the vertical direction. The upper push switch 10 sends a signal to the prompt bus 1150 (refer to Figure 5 ) is switched on and off. In the present embodiment, the upper push switch 10 is pressed in from the off state to turn on, and then the on state is maintained even if the pressing of the upper push switch 10 is released. In addition, the upper push switch 10 is pressed in again from the on state to turn off, and then the off state is maintained even if the pressing of the upper push switch 10 is released.

[0110] In addition, the signal of input ch 1120 is taken out from positions P1 to P3 (refer to Figure 6) can be determined, for example, by the option setting displayed in the second area 2a2 of the display surface 2a. In addition, the extraction positions P1 to P3 of the signal of the input ch 1120 can be determined, for example, by detecting the change in the amount of depression of the push switch 10 in multiple stages. Specifically, when the user's finger only touches the push switch 10 but does not press the push switch 10, the signal extraction position P1 is determined, and when the finger presses the push switch 10 halfway, the signal extraction position P2 can be determined. In addition, when the finger presses the push switch 10 completely, the signal extraction position P3 can be determined.

[0111] Fig.10 A second display example of the display screen 2a of the processing device 1 according to the present embodiment is shown.

[0112] exist Fig.10 In the second display example, a plurality of mixing bus names 511 and output level information 512 of a plurality of input channels 1120 corresponding to each mixing bus 1130 are displayed in the second area 2 a 2 of the display surface 2 a .

[0113] A plurality of mixing bus names 511 are arranged in the left-right direction at the lower end of the second area 2a2, and correspond to the plurality of channel strips arranged in the left-right direction. The number of mixing bus names 511 displayed in the second area 2a2 corresponds to the number of channel strips, which is 8.

[0114] exist Fig.10 The displayed mixing bus name 511 is the aforementioned plurality of mixing buses 1130 (see Figure 5 ) can be switched to display of other mixing bus names 511 by the user performing a predetermined operation on the processing device 1. For example, when the number of mixing buses 1130 of the processing device 1 is 16, the plurality of mixing bus names 511 displayed in the second area 2a2 can be switched to the first to eighth mixing buses 1130 (Mix1 to 8) and the ninth to sixteenth mixing buses 1130 (Mix9 to 16) by the user performing a predetermined operation on the processing device 1. The switching of the display of the mixing bus names 511 can be performed, for example, by sliding the user's finger in a manner such that the user sequentially touches the plurality of push switches 10 arranged in the left-right direction.

[0115] Output level information 512 of a plurality of input channels 1120 corresponding to each mixing bus 1130 is arranged above each mixing bus name 511. In the output level information 512, an output level 513 of each input channel 1120 is indicated by a gauge extending in the left-right direction. The number of input channels 1120 corresponding to each mixing bus 1130 is Figure 5 The number (N) shown in .

[0116] The output levels 513 can be changed / adjusted by, for example, the user touching the output levels 513 displayed in the second area 2a2 and directly operating. In addition, the output levels 513 can be changed / adjusted by, for example, the user operating the first encoder 20.

[0117] When the first encoder 20 is used, the output level 513 can be changed / adjusted by the user rotating the rotation operation unit 22. When the first encoder 20 is used, for example, when the user's finger does not push the push operation unit 25 or does not touch the push operation unit 25, the output level 513 can be roughly changed / adjusted by the user rotating the rotation operation unit 22. In addition, when the user's finger pushes the push operation unit 25 or touches the push operation unit 25, the output level 513 can be finely changed / adjusted by the user rotating the rotation operation unit 22. When the user's finger pushes the push operation unit 25 or touches the push operation unit 25, for example, an icon indicating that the output level 513 is finely changed / adjusted can be visually confirmed through the key top 26 of the push operation unit 25.

[0118] exist Fig.10 In the second example, Fig. 9 Similarly to the first display example, icons 501 and 502 corresponding to the plurality of push switches 10 are displayed in the first area 2a1. In addition, the icon 501 including "ON" corresponds to the lower push switch 10 of the two push switches 10 arranged in the vertical direction, and the icon 502 including "CUE" corresponds to the upper push switch 10.

[0119] The lower push switch 10 corresponding to the icon 501 including "ON" switches on and off the transmission of the signal from the specified mixing bus 1130 (for example, Mix1) displayed in the mixing bus name 511 to the output connector 1170 by pressing it. The specified lower push switch 10 and the corresponding specified mixing bus 1130 are arranged in the vertical direction.

[0120] The upper push switch 10 corresponding to the icon 502 including "CUE" is assigned to the cue switching switch 1146 (see FIG. 1146 ) of the output channel 1140 connected to the subsequent stage of the specified mixing bus 1130 (for example, Mix1) displayed in the mixing bus name 511. Figure 7The upper push switch 10 and the corresponding mixing bus 1130 are arranged in the vertical direction. The upper push switch 10 is pressed to switch the mixing bus 1130 to the prompt bus 1150 ( Figure 5 The operation is performed by switching on and off the sending of the signal of reference).

[0121] Next, refer to Figures 11 to 15 , an example of the relationship between the operation of the push switch 10 by the user's finger F and the change in the display mode of the icon 501 corresponding to the push switch 10 is described.

[0122] For example Fig.11 As shown in FIG. 1 , when the user's finger F touches the top surface 11 a of the push switch 10 , the display mode of the icon 501 is changed in accordance with the change in capacitance between the display surface 2 a and the finger F. Fig.11 In the example shown, the characters and colors of the icon 501 are changed. Specifically, the icon 501 corresponding to the push switch 10 that is not touched by the user's finger F and is in the off state is displayed with the characters "OFF" and in white, and the icon 501 corresponding to the push switch 10 that is in the off state and touched by the user's finger F is displayed with the characters "SEL" and in light gray. By the difference in the display method of the icon 501, the user can recognize that the finger F touches the push switch 10 that is in the off state. The characters "SEL" indicate that the finger F touches the push switch 10 to select the push switch 10, and selects the channel corresponding to the channel strip to which the push switch 10 belongs. At this time, the parameters of the channel selected by the finger F touching the push switch 10 are displayed in the second area 2a2 of the display surface 2a (for example, Fig. 9 Information 505 of the signal processing unit illustrated.

[0123] If the user's finger F touches the top surface 11a of the push switch 10, as shown in FIG. Fig.12 As shown, the push switch 10 is pressed into the display surface 2a by the user's finger F, and the push switch 10 is turned on in accordance with the change in capacitance between the display surface 2a and the finger F, and the display mode of the icon 501 is further changed. Specifically, the icon 501 corresponding to the push switch 10 is changed from "SEL" to the character "ON", and the color of the icon 501 is changed from light gray to dark gray. The icon 501 shown with the character "ON" and dark gray indicates that the push switch 10 is in the on state. By the difference in the display mode of the icon 501, the user can recognize that the push switch 10 has been switched from the off state to the on state.

[0124] In this embodiment, after the push switch 10 is pressed in and switched to the on state, even if the push switch 10 is released from being pressed, the on state of the push switch 10 is maintained. Fig.13 As shown, by releasing the finger F from pressing the push switch 10 in the on state, the display mode of the icon 501 does not change even if the capacitance between the display surface 2a and the finger F changes. The character remains "ON" and the color remains dark gray. Furthermore, even if the finger F leaves the push switch 10, the on state of the push switch 10 is maintained, and the display mode of the icon 501 remains "ON" and the color remains dark gray.

[0125] like Fig.14 As shown in FIG. 1 , when the push switch 10 in the on state is pressed toward the display surface 2a by the user's finger F, the on state of the push switch 10 is maintained. Therefore, even if the capacitance changes with the pressing action of the user's finger F on the push switch 10, the display mode of the icon 501 does not change, the character scale "ON" remains unchanged, and the color remains dark gray.

[0126] Then, if Fig.15 As shown, if the finger F is released from pressing the push switch 10, the push switch 10 changes to the off state in accordance with the change in capacitance between the display surface 2a and the finger F, and the display mode of the icon 501 changes. Specifically, the icon 501 corresponding to the push switch 10 changes from "ON" to the character "SEL", and the color of the icon 501 changes from dark gray to light gray. Furthermore, by removing the finger F from the top surface 11a of the push switch 10, the icon 501 changes from "SEL" to the character "OFF", and the color of the icon 501 changes from light gray to white. By changing the display mode of the icon 501 in this way, the user can recognize that the push switch 10 has been switched from the on state to the off state.

[0127] exist Figures 11 to 15 In the example shown, white, light gray, and dark gray are used as a combination of three colors of the icon 501 indicating the state of the push switch 10, but any combination of colors such as cyan, yellow, and red may be used.

[0128] The relationship between the operation of the push switch 10 by the user's finger F and the change in the display mode of the icon 501 corresponding to the push switch 10 is not limited to the above.

[0129] For example, when the finger F is in the OFF state and the corresponding icon 501 is displayed with the character "SEL" due to the touch of the user's finger F, the icon 501 may be changed from "SEL" to "OFF".

[0130] In addition, for example, when the user's finger F touches the push switch 10 which is in the on state and the corresponding icon 501 is displayed with the character "ON", the icon 501 can be changed from "ON" to the character "SEL". Then, when the finger F is released from the push switch 10, the icon 501 can be changed from "SEL" to "ON".

[0131] As described above, according to the processing device 1 of the present embodiment, the touch panel 2 detects the change in capacitance accompanying the operation of the first physical operating member 3. Therefore, the touch panel 2 can detect different changes in capacitance according to the type of operation of the user on the first physical operating member 3 (for example, the operation of touching the first physical operating member 3, the operation of moving the first physical operating member 3). That is, one first physical operating member 3 can have multiple functions. Thus, the number of first physical operating members 3 provided in the processing device 1 can be reduced. Therefore, the processing device 1 can be made compact. In addition, by reducing the number of first physical operating members 3, the manufacturing cost of the processing device 1 can also be reduced.

[0132] In addition, even if the user does not look at the processing device 1, the user can know where the finger is touching by touching the first physical operation element 3 with his or her finger. For example, when the user touches the first physical operation element 3 with his or her finger, the user can find the right time to operate the first physical operation element 3 while observing other places. Therefore, the usability (ease of use) of the processing device 1 can be ensured.

[0133] Furthermore, in the processing device 1 of the present embodiment, the key tops 11 and 26 of the push switch 10 and the first encoder 20 serve as light-transmitting portions that transmit light. Thus, the user can visually check the icons displayed on the display surface 2a by pressing the key tops 11 and 26 of the push switch 10 and the first encoder 20, thereby being able to easily grasp the functions of the push switch 10 and the first encoder 20.

[0134] In the processing device 1 of the present embodiment, the mechanism for detecting the change in capacitance is the same in the first area 2a1 and the second area 2a2 in the touch panel 2. Therefore, the structure of the touch panel 2 can be simplified compared to the case where the mechanism for detecting the change in capacitance is different between the first area 2a1 and the second area 2a2.

[0135] Furthermore, in the processing device 1 of the present embodiment, in the first area 2a1 where the first physical operating element 3 is configured, the distance between the display surface 2a and the finger of the user who operates the first physical operating element 3 is greater than the distance between the display surface 2a and the finger of the user in the second area 2a2 where the first physical operating element 3 is not configured. Therefore, in the first area 2a1, the capacitance generated between the display surface 2a and the finger of the user becomes smaller than that in the second area 2a2. In contrast, by making the sensitivity of detecting the change in capacitance in the first area 2a1 higher than that in the second area 2a2, the touch panel 2 can accurately detect the change in capacitance based on the operation of the first physical operating element 3 by the user's finger.

[0136] For example, in the case where the first physical operating member 3 is a push switch 10 that can be pressed, even if the change in the amount of pressure pressed by the user's finger on the push switch 10, that is, the change in the distance between the user's finger touching the top surface 11a of the push switch 10 and the touch panel 2 is small, the touch panel 2 can accurately detect the change in the distance.

[0137] In addition, the processing device 1 of this embodiment detects capacitance in multiple stages in the first area 2a1 where the push switch 10 is arranged. Thus, the touch panel 2 can detect changes in the amount of depression of the push switch 10 by the user's finger in multiple stages. For example, the touch panel 2 can detect three stages: the first stage when the user's finger contacts the push switch 10, the second stage when the push switch 10 is halfway depressed, and the third stage when the push switch 10 is fully depressed.

[0138] Furthermore, in the processing device 1 of the present embodiment, the plurality of first physical operating elements 3 are integrally supported by the support body 5. Therefore, the relative positions of the plurality of first physical operating elements 3 are fixed, and the plurality of first physical operating elements 3 can be processed as one operating element module. Thus, the plurality of first physical operating elements 3 can be simultaneously and easily arranged on the display surface 2a.

[0139] In addition, in the processing device 1 of this embodiment, a plurality of push switches 10 are connected. Therefore, the relative positions of the plurality of push switches 10 are fixed, and the plurality of push switches 10 can be processed as one module. Thus, the plurality of push switches 10 can be simultaneously and easily arranged on the display surface 2a.

[0140] Furthermore, in the processing device 1 of this embodiment, the plurality of first physical operating elements 3 can be freely installed and removed relative to the display surface 2a. Thus, the first physical operating elements 3 can be arranged at positions on the display surface 2a that are easy for the user to use. In addition, the first area 2a1 with high capacitance sensitivity in the display surface 2a can be appropriately set to match the position where the first physical operating element 3 is arranged.

[0141] In addition, in the processing device 1 of the present embodiment, the control unit changes the processing parameters by sliding the user's finger in a manner of sequentially touching the plurality of push switches 10. The plurality of push switches 10 arranged on the display surface 2a of the touch panel 2 can be used to change the processing parameters by an intuitive operation such as sequentially touching the plurality of push switches 10. Moreover, by adding a new operation method (function) of sequentially touching the plurality of push switches 10, the number of push switches 10 provided in the processing device 1 can be reduced, thereby further achieving a compact processing device 1 and a reduction in manufacturing cost.

[0142] Furthermore, in the processing device 1 of the present embodiment, the touch panel 2 detects the contact of the user's finger to the push switch 10 and the pressing of the push switch 10 based on the change in capacitance. Thus, one push switch 10 can have at least two functions (contact function and pressing function). In addition, in the present embodiment, multiple push switches 10 can also have the aforementioned new one function (sliding function).

[0143] In addition, in the processing device 1 of the present embodiment, the top surface 11a of the key top 11 of the push switch 10 touched by the user's finger is recessed in a concave shape. Therefore, compared with the case where the top surface 11a is not recessed, the user's finger touching the top surface 11a can be brought closer to the display surface 2a of the touch panel 2. Thus, even if the touch panel 2 has a low sensitivity for detecting a change in capacitance, it is possible to more reliably detect that the user's finger has touched the push switch 10 through a change in capacitance.

[0144] Furthermore, in the processing device 1 of this embodiment, the touch panel 2 detects both the contact of the user's finger with the first encoder 20 and the rotation operation of the first encoder 20 based on the change in capacitance. Thus, one first encoder 20 can have two functions (contact function and rotation function).

[0145] In addition, in the processing device 1 of the present embodiment, the first encoder 20 has a cylindrical rotation operation unit 22 that is rotated by the user's fingers, and a push operation unit 25 that is pushed by the user's fingers. Thus, one first encoder 20 can also have one function (push-in function). In addition, since one first encoder 20 has a rotation function and a push-in function, various operations can be performed. For example, a new operation of rotating the rotation operation unit 22 while pressing the push operation unit 25 can be performed. In addition, an operation of selecting a function or process by rotating the rotation operation unit 22 and determining a function or process by pressing the push operation unit 25 can also be performed.

[0146] Furthermore, in the processing device 1 of the present embodiment, the first encoder 20 includes a fixed portion 21 fixed to the touch panel 2, a rotational operation portion 22 capable of rotational operation relative to the fixed portion 21, and a bearing 23 provided between the fixed portion 21 and the rotational operation portion 22. Thus, the rotational operation portion 22 can be smoothly rotated by the bearing 23.

[0147] In addition, in the processing device 1 of the present embodiment, the function selection unit changes the icon along with the change of the processing parameter based on the operation of the first physical operating element 3. For example, the color of the icon is changed along with the change of the parameter based on the contact operation and the pressing operation of the push switch 10. As described above, the icon visually confirmed by the first physical operating element 3 changes in accordance with the operation of the first physical operating element 3, thereby allowing the user to easily grasp the state of the processing parameter obtained based on the operation of the first physical operating element 3.

[0148] As mentioned above, although this invention was demonstrated in detail, this invention is not limited to the said embodiment, Various changes can be added within the range which does not deviate from the summary of this invention.

[0149] In the present invention, the push switch 10 may include, for example, a switch body and a conductive layer applied on the surface of the switch body. The switch body may be the key top 11 of the above embodiment.

[0150] The conductive layer is applied to the surface of the switch body (key top 11), which means that the area of ​​the switch body touched by the finger and the area facing the display surface 2a are electrically connected through the conductive layer. Therefore, even if the sensitivity of the touch panel 2 to detect the change in capacitance is low, and even if the distance between the finger of the user touching the switch body and the display surface 2a is large, the touch panel 2 can accurately detect the change in capacitance caused by the finger touching and pressing the push switch 10.

[0151] The structure coated with the conductive layer is not limited to the push switch 10 , and can also be applied to the push operation portion 25 of the first encoder 20 , for example.

[0152] In the present invention, the push switch 10 is not limited to being used as an "ON" switch (ON / OFF switch) or a "CUE" switch, and can be used as a "SEL" switch or a user-defined key. In addition, the "SEL" switch can be a switch (selection switch) for selecting a channel whose processing parameters are changed / adjusted by a physical operation element.

[0153] In the present invention, the push switch 10 used as an "ON" switch is not limited to functioning as a simple ON / OFF switch. For example, it can function as "SEL" (select) in response to a finger touching the push switch 10, and function as an ON / OFF switch in response to the push switch 10 being pressed.

[0154] In the present invention, the display form (eg, color) of the icon may be changed in multiple stages according to changes in the amount of depression of the push switch 10 , for example.

[0155] In the present invention, for example, the first encoder 20 may not include the pressing operation portion 25 and may only be capable of rotational operation. Even the first encoder 20 having such a structure may include a light transmitting portion that transmits light.

[0156] In the present invention, the first encoder 20 may be an encoder with no limit on the range of the rotation operation, or an encoder with a limit on the range of the rotation operation. In addition, the value of the processing parameter that changes with the rotation operation of the first encoder 20 may have an upper limit value and a lower limit value, or may not have the upper limit value and the lower limit value.

[0157] In the present invention, for the first physical operating element 3 disposed in the first area 2a1 of the display surface 2a, for example, the following can be applied: Fig.16 , 17 The slider 30 is shown as being operable to be linearly moved along the display surface 2a. In this case, the touch panel 2 detects the linear movement operation of the slider 30 based on the change in capacitance.

[0158] The hair clipper 30 includes a handle 31 and a cover 32. The handle 31 is a portion operated by a user's finger. The cover 32 is disposed on the display surface 2a. The cover 32 includes a guide groove 34. The guide groove 34 is formed in a groove shape extending in a straight line, and the handle 31 is arranged in a straight line direction (in the direction of the hair clipper 30). Fig.16 The cover portion 32 may be guided in the vertical direction. For example, the cover portion 32 may be connected to the support body 5 (see Figures 1 to 3 ) are formed integrally.

[0159] Specifically, the handle portion 31 is disposed on the upper surface 32a of the cover portion 32. The handle portion 31 is integrally formed with an insertion portion 33 that is inserted into the guide groove 34 of the cover portion 32. The front end portion of the insertion portion 33 extending from the handle portion 31 may be as shown in FIG. Fig.17 By inserting the insertion portion 33 into the guide groove 34, the handle portion 31 can be moved along the length direction of the guide groove 34 (in the direction of the guide groove 34). Fig.16 In the middle, it is guided in the up and down directions.

[0160] An elastic body 35 that is elastically deformable is disposed between the handle 31 and the upper surface 32a of the cover 32. Thus, in the hair clip 30, a pressing operation of pressing the handle 31 toward the display surface 2a is also possible. The touch panel 2 detects the pressing of the handle 31 by the user's finger based on the change in capacitance.

[0161] In addition, Fig.16 , 17 In the hair clipper 30 shown in the figure, the cover portion 32 is provided with a width direction of the guide groove 34 (in Fig.16 , 17 In the embodiment of the present invention, a portion 321 adjacent to the cover portion 32 in the left-right direction (in the left-right direction) is formed as a light-transmitting portion through which light can pass. Furthermore, an icon associated with a processing parameter is displayed in a region of the display surface 2a that overlaps with the guide groove 34 in the cover portion 32 and the portion 321 of the cover portion 32 formed as a light-transmitting portion. The icon may be, for example, a meter indicating a gain value of a processing parameter (for example, output speech) output from the input ch 1120 and the output ch 1140. The meter may extend in the length direction of the guide groove 34. In addition, the icon may be, for example, Fig.16 Shown is a scale 521 of processing parameters.

[0162] In addition, Fig.16 , 17 In the illustrated clipper 30 , the handle portion 31 is formed as a light-transmitting portion through which light can pass.

[0163] exist Fig.16 , 17 In the illustrated fader 30, the gain value of the processing parameter (for example, output voice) changed based on the operation of the knob portion 31 can be displayed in an area corresponding to the guide groove 34 or the portion 321 of the cover portion 32 adjacent to the guide groove 34 in the display surface 2a. As a result, the size of the fader 30 in the width direction of the guide groove 34 can be reduced. That is, the fader 30 can be configured compactly.

[0164] In addition, Fig.16 , 17 In the illustrated fader 30, the knob portion 31 is formed as a light-transmitting portion, and thus, by displaying an icon representing the function of the fader 30 in a region of the display surface 2a corresponding to the position of the knob portion 31, it is possible to easily understand the function assigned to the fader 30. Furthermore, even if the function assigned to the fader 30 is changed, the information representing the function of the fader 30 can be simply changed by simply changing the icon displayed on the display surface 2a.

[0165] exist Fig.16 , 17In the illustrated fader 30, the touch panel 2 detects the contact of the user's finger with the knob 31, the pressing of the knob 31, and the linear movement of the knob 31 based on the change in capacitance. Thus, one fader 30 can have multiple functions. For example, by moving the knob 31 linearly while touching the knob 31, the volume of the sound that the user is listening to through headphones or the like can be adjusted. In addition, by moving the knob 31 linearly while pressing the knob 31, the volume of the output sound can be adjusted. In addition, for example, by moving the knob 31 linearly while touching the knob 31, the volume can be roughly adjusted, and by moving the knob 31 linearly while pressing the knob 31, the volume can be finely adjusted.

[0166] In the present invention, Figures 1 to 3 The push switch 10 and the first encoder 20 shown in the example, and Fig.16 , 17 The illustrated faders 30 may be provided in the same processing device.

[0167] In the present invention, for example, the plurality of first physical operating elements 3 may be individually disposed on the display surface 2a of the touch panel 2. In addition, the plurality of first physical operating elements 3 may be individually attachable to and detachable from the display surface 2a of the touch panel 2.

[0168] The processing device of the present invention can also be applied to, for example, an image processing device that performs signal processing on an input image signal (signal associated with an image) and outputs it to the outside. In this case, the icon displayed on the display surface 2a and associated with the processing parameter can be, for example, an animation. In this case, by displaying the icon as a sample animation (thumbnail animation) after processing by the image processing device, the user can easily compare the image with and without processing.

[0169] Furthermore, the processing device of the present invention can also be applied to, for example, electronic musical instruments that output sounds.

[0170] For example, in the case where the processing device of the present invention is applied to a synthesizer as a kind of electronic musical instrument, it can be imagined that various waveforms (sawtooth waves, rectangular waves, recorded sound signals) are input into the channel as signals, and an effector for implementing appropriate sound to the waveform is used as a processing parameter, and a simple image simulating the effector is displayed through a physical operating member as an icon. Thus, the effect can be turned on and off for the waveform in accordance with the user's operation on the physical operating member. In addition, by setting it to detect the capacitance in multiple stages or without stages, the degree of application of the effect can be adjusted, for example, in accordance with the amount of depression of the push switch (the position of the finger relative to the display surface of the touch panel). In addition, by applying special effects that appear only when sliding operations are performed on multiple physical operating members (for example, adding overtones to the input waveform and applying reverberation extremely deeply), a visual performance effect achieved through performance techniques can be obtained.

[0171] In addition, when the processing device of the present invention is applied to a sampler as a kind of electronic musical instrument, it can be imagined that the sampled sound source is associated with each physical operating member, and when the physical operating member is operated, the sound source is input to the channel to produce sound (in this case, the channel corresponds to the output channel). In addition, as a processing parameter, a parameter that determines whether to make the sampled sound source flow through the channel is used. At this time, in the case where the physical operating member accepts the position of the finger at multiple stages, the volume of the sound source can be determined by, for example, the amount of pressure of the push switch (the position of the finger relative to the display surface of the touch panel). In addition, for the sliding operation, special effects can be pre-defined in the same way as in the example of the synthesizer.
