Specification

Operation panel and information equipment

Technical field

[0001] The present invention relates to an operation panel provided in a DJ device or the like and an information device such as a DJ device including such an operation panel.

Background art

[0002] For example, on a CD or DVD, a plurality of music (ie, content data) forces are recorded in association with each other. More specifically, for example, it is recorded as a plurality of data groups distinguished by each music power track number having a predetermined reproduction time. For this reason, the DJ player can perform cue playback that searches and plays back the start address of each music, random playback that arbitrarily changes the playback order of each music piece, and the like. You can also change the volume of the music to be played and change the tempo.

[0003] Furthermore, by using a mixer, it is possible to mix music and the like reproduced by a plurality of DJ players. For example, suppose that music being played by another DJ player is mixed when music being played by one DJ player is flowing from the power. In this case, by operating the crossfader, etc., the music output from the mixer is shifted to the music played by the other DJ player. Music playback can be continued while connecting two different music smoothly. Or, for example, by lowering the volume of music being played by one DJ player while increasing the volume of music being played by another DJ player, Playback can be continued.

[0004] In addition, various effect effects can be imparted to music played back by using an effector. Depending on the function of the effector, for example, it generates a delay sound, generates an echo sound, shakes the sound left and right, adds an effect effect such that the jet machine periodically rises and falls, It can be cut periodically.

Such an operation is executed, for example, when a user operates an operation switch. Specific examples of the operation switch include a slider switch that can slide back and forth (in other words, a slider volume, etc.) and a rotary switch that can rotate (in other words, a rotary volume, etc.).

In addition, the optical disk playback apparatus according to the present embodiment described below is used for continuous playback while adding various special effects (effects) to music data or video data in a ballroom such as a club or disco. Used as DJ equipment used in Note that “DJ” in the present embodiment is intended to indicate that contents in a broad sense including not only music but also video and the like are reproduced using a special technique.

First, the basic configuration of the DJ playback system 1 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram schematically showing the basic configuration of the playback system 1 for DJ according to the present embodiment.

As shown in FIG. 1, a DJ playback system 1 according to the present embodiment includes a plurality of optical disk playback devices 2 (specifically, 2a and 2b) and a mixer 3.

The optical disk playback devices 2a and 2b have a function of playing back video data and music data recorded on the optical disks 100a and 100b, respectively. The reproduced video and music are output to mixer 2. The detailed configuration of the optical disc reproducing apparatus 2 will be described later in detail (see FIG. 2).

[0036] The mixer 3 constitutes a specific example of the "information device" in the present invention, and combines the video data and music data reproduced by the optical disk reproducing devices 2a and 2b, respectively. It has a function to combine video data and music data (mixing function). Further, the mixer 3 has a function of giving predetermined video effect effects and music effect effects to the video data and music data reproduced by the optical disc reproducing apparatuses 2a and 2b, respectively, as necessary. Yes. The video data and music data to which the video effect effect and the music effect effect are added or combined into one by the mixer 3 are output to an external output device such as a display or a speaker. As a result, the video and music are played back on the external output device.

[0037] Next, with reference to FIG. 2, the basic configuration of the optical disc playback apparatus 2 according to the present embodiment will be described. FIG. 2 shows the basics of the optical disc playback apparatus 2 according to the present embodiment. It is a block diagram which shows a structure notionally.

As shown in FIG. 2, the optical disk reproducing apparatus 2 includes an optical pickup (PU: Pick Up) 210, an RF (Radio Frequency) amplifier 211, a spindle motor 212, a servo mechanism 213, and a pickup servo circuit. 214, content data decoding unit 215, decoding unit 216, control data decoding unit 217, spindle servo circuit 218, external output terminal 260, system controller 220, memory 221, operation unit 240, The display unit 250 is provided.

[0039] The optical pickup 210 is for reading content data including video data and music data and control data from the optical disc 100, and also includes a semiconductor laser device, various lenses, an actuator, and the like. More specifically, the optical pickup 210 irradiates the optical disc 100 with the laser beam LB with a predetermined power. In addition, a PD (Photo Detector) sensor for receiving the reflected light of the laser beam LB from the optical disk 100 is provided, and the received reflected light is output to the RF amplifier 211 as a read signal.

The optical pickup 210 is configured to move in the radial direction of the optical disc 100 in accordance with a tracking error signal by an actuator, a slider, etc. (not shown) driven by the control of the servo mechanism 213. The focus is controlled by changing the focus of the laser beam LB in accordance with the focus error signal under the control of the servo mechanism 213.

The RF amplifier 211 generates an RF signal based on the read signal output from the optical pickup 210, and outputs the generated RF signal to each of the content data decoding unit 215 and the control data decoding unit 217. The RF amplifier 211 also controls the focus error signal and the optical pickup 210 for controlling the focus when the optical pickup 210 irradiates the optical disc 100 with the laser beam LB based on the read signal output from the optical pickup 210. Generates an error signal such as a tracking error signal for controlling tracking when the optical disc 100 is irradiated with the laser beam LB. The generated error signal is output to the pickup servo circuit 214.

The spindle motor 212 is configured to rotate the optical disc 100 at a predetermined speed while receiving spindle servo from the spindle servo circuit 218.

[0043] The servo mechanism 213 is a tracking servo output from the pickup servo circuit 214. The optical pickup 210 is moved in the radial direction of the optical disc 100 based on the control signal. Further, based on a focus servo control signal output from the pickup servo circuit 214, the objective lens included in the optical pickup 210 is moved along the optical axis of the laser beam LB.

The pickup servo circuit 214 generates a focus servo control signal and a tracking servo control signal for controlling the servo mechanism 213 based on the error signal output from the RF amplifier 211. The generated focus servo control signal and tracking servo control signal are output to the servo mechanism 213. In other words, the servo mechanism 213 is feedback controlled based on the error signal output from the RF amplifier 211 that suppresses the occurrence of a focus error or tracking error.

The content data decoding unit 215 generates a stream signal including a video stream and an audio stream by decoding the RF signal output from the RF amplifier 211. The generated stream signal is output to the decoding unit 216.

[0046] Decoding section 216 decodes the stream signal and generates a reproduction signal. The generated reproduction signal is output to the mixer 3 via the external output terminal 260.

[0047] The control data decoding unit 217 generates control data for controlling the reproduction of the content data by decoding the RF signal output from the RF amplifier 211. The control data includes, for example, TOC data recorded in the lead-in area of the optical disc 100, synchronization data recorded in the stream signal, and subcode that includes time lapse information when content data is played back. Data is an example. The generated control data is output to the system controller 220 and used to control the reproduction of the content data.

[0048] The spindle servo circuit 218 detects an error in the synchronization data with respect to the rotation speed of the spindle motor 212 instructed by the system controller 220, and feedback-controls the rotation of the spindle motor 212 to suppress the occurrence of the error. .

[0049] The system controller 220 includes a microprocessor (MPU), and centrally controls the operation of the entire optical disc playback apparatus 2 by executing a system program (or firmware or the like) that is set in advance. [0050] The memory 221 includes a RAM area for temporarily storing various data necessary for the operation of the optical disc playback apparatus 2, a ROM area for storing a system program for defining the operation of the system controller 220, and the like. And

In addition, an operation unit 240 and a display unit 250 are connected to the system controller 220. Instruction data from various operation keys provided in the operation unit 240 is output to the system controller 220, and the system controller 220 controls the reproduction of the content data according to the instruction data. Further, the system controller 220 controls the display operation on the display unit 250.

The operation unit 240 includes a jog dial 241, a pulse counter 242, and a display unit 250.

The jog dial 241 is a disk-shaped operation key that is rotatable in both directions. When the user or the like operates the jog dial 241 while appropriately changing the rotation direction and rotation speed, forward playback and reverse playback can be set according to the rotation direction, and further, the speaker or the like can be set according to the rotation speed. Now you can change the tone of music played on headphones!

[0054] Note that the above-mentioned forward reproduction is the same as when the analog record such as LP is rotated in the forward direction to reproduce the image or music, and the content data on the optical disc 100 is recorded in the order in which they are recorded. Say to play. Therefore, as the jog dial 241 is rotated in the clockwise direction, the video is reproduced in the direction along the reproduction time axis, and the music is reproduced as a normal sound. In this embodiment, forward playback is also performed when the jog dial 241 is stopped!

[0055] On the other hand, the reverse playback described above is the reverse of the order in which the content data of the optical disc 100 is recorded, as in the case of playing an image or music by rotating an analog record in the reverse direction. Say to play in order. In other words, since video and music are recorded continuously (analog recording) in analog records, rotating the analog record in the reverse direction will play the video and music in the reverse direction, Unlike the music, onomatopoeia will be played, but if the jog dial 241 is rotated counterclockwise, the individual content data digitally recorded on the optical disc 100 will be reversed. By playing with, the force will also produce the same onomatopoeia as if the analog record was rotated in the opposite direction!

[0056] By providing the same function as that for reverse playback of an analog record in this way, for example, when the user or the like repeatedly rotates the jog dial 241 in the clockwise and counterclockwise directions, It can generate onomatopoeia (sounds such as “Kyukyu” and “Gashagasha”) called scratch sounds. When a so-called disc jockey player operates the jog dial 241 to generate the above-described scratch sound or the like, it is possible to perform editing for generating rap music or the like using CD or DV D. Yes.

[0057] The pulse counter 242 detects the rotational speed (or angular velocity) of the jog dial 241 by counting the pulse width (or the number of pulses, etc.) of the pulses generated as the jog dial 241 is rotated. Power! ] Detect the direction of rotation of the jog dial 241 based on the pulse generated when the jog dial 241 is rotated. The detected rotation direction and rotation speed of the jog dial 241 are output to the system controller 220. As a result, the system controller 220 recognizes the operation amount of the jog dial 24 1 operated by the user or the like.

[0058] The display unit 250 displays various information associated with the reproduction of video and music included in the content data. The display unit 250 includes a display panel such as a liquid crystal display or a fluorescent tube, and displays various types of information under the control of the system controller 220. For example, the display unit 250 displays the track number of the currently played video or music, the elapsed time of the currently played video or music (ie, the current playback time), or the current optical disc playback device 2. The total number of tracks of video and music recorded on the loaded optical disc 100 is displayed. In addition, the display unit 250 displays a wave display of the beat density of music along the playback time axis. Alternatively, the signal intensity for each frequency band of the currently played music may be displayed in waves.

[0059] Of course, the display content on the display unit 250 described here is just a specific example, and it goes without saying that various other information may be displayed.

Subsequently, the basic configuration of the mixer 3 according to the present embodiment will be described with reference to FIG. Here, FIG. 3 is a plan view conceptually showing the basic external structure of the mixer 3 according to the present embodiment. FIG.

As shown in FIG. 3, the mixer 3 includes an input terminal 301, an input terminal 302, an equalizer rotary volume 311, an equalizer rotary volume 312, an equalizer rotary volume 313, and an equalizer rotary volume 314. Rotary volume 315 for equalizer, rotary volume 316 for equalizer, slide fader 321, slide fader 322, crossfader 323 for music, crossfader 324 for video, and rotary volume 331 for effects , Effect rotary volume 332, effect rotary volume 333, effect rotary volume 334, effect ONZOFF switch 336, effect rotary volume 341, and effect rotary A volume 342, and the effect for rotary volume 3 43, and the effect for a rotary volume 344, and the effect ON / OFF switch 346, and a display unit 361.

[0062] The input terminal 301 is a terminal for inputting video and music output from the optical disc playback apparatus 2a. Hereinafter, the video data and music data input to the mixer 3 via the input terminal 301 are referred to as CH1 (channel 1) video data and music data.

[0063] The input terminal 302 is a terminal for inputting video and music output from the optical disc playback apparatus 2b. Hereinafter, the video data and music data input to the mixer 3 via the input terminal 302 are referred to as CH2 (channel 2) video data and music data.

[0064] The equalizer rotary volume 311 is operated by the user in order to adjust the high frequency range of the music data of CH1. For example, turning the equalizer rotary volume 311 clockwise (ie, to the right) can increase the high-frequency range of the CH1 music data. On the other hand, turning the equalizer rotary volume 311 counterclockwise (that is, to the left) can reduce the high frequency level of the CH1 music data.

[0065] The equalizer rotary volume 312 is operated by the user to adjust the mid-range level of the CH1 music data. For example, turning the equalizer rotary volume 312 clockwise (that is, to the right) can increase the mid-range level of CH1 music data. On the other hand, counter rotary volume 312 for equalizer Turning it around (that is, to the left) can reduce the midrange level of the CH1 music data.

[0066] The equalizer rotary volume 313 is operated by the user in order to adjust the bass level of the CH1 music data. For example, if the equalizer rotary volume 313 is turned clockwise (ie, clockwise), the bass level of the CH1 music data can be increased. On the other hand, if the equalizer rotary volume 313 is turned counterclockwise (that is, leftward), the low frequency level of the CH1 music data can be reduced.

[0067] The equalizer rotary volume 314 is operated by the user to adjust the level of the high frequency range of the CH2 music data. For example, if the equalizer rotary volume 314 is rotated clockwise (ie, clockwise), the high frequency level of the CH2 music data can be increased. On the other hand, if the equalizer rotary volume 314 is turned counterclockwise (ie, leftward), the high frequency level of the CH2 music data can be reduced.

[0068] The equalizer rotary volume 315 is operated by the user to adjust the mid-range level of the CH2 music data. For example, turning the equalizer rotary volume 315 clockwise (ie, in the right direction) can increase the mid-range level of the CH2 music data. On the other hand, turning the equalizer rotary volume 315 counterclockwise (that is, to the left) can reduce the level of the midrange of CH2 music data.

[0069] The equalizer rotary volume 316 is operated by the user in order to adjust the low frequency level of the CH2 music data. For example, if the equalizer rotary volume 316 is turned clockwise (ie, clockwise), the bass level of the CH2 music data can be increased. On the other hand, if the equalizer rotary volume 316 is turned counterclockwise (that is, leftward), the bass level of the CH2 music data can be reduced.

[0070] The slide fader 321 is operated by the user to adjust the output level (in other words, volume) of the music data of CH1. For example, slide fader 321 up By driving in the direction, the output level of CHI music data can be increased. On the other hand, if the slide fader 321 is moved downward, the output level of the music data of CH1 can be reduced.

Note that the slide fader 321 may be configured to be operated by the user in order to adjust the output level (for example, luminance) of the CH1 video data.

[0072] The slide fader 322 is operated by the user in order to adjust the output level (in other words, volume) of the CH2 music data. For example, if the slide fader 322 is powered up, the output level of CH2 music data can be increased. On the other hand, if the slide fader 322 is moved downward, the output level of the CH2 music data can be reduced.

Note that the slide fader 322 may be configured to be operated by the user in order to adjust the output level (for example, luminance) of the CH2 video data.

[0074] The music crossfader 323 constitutes one specific example of the "first controller" in the present invention, and in order to adjust the ratio of combining the music data of CH1 and the music data of CH2, Operated by the user. Specifically, the user grabs the knob 325 provided in the music crossfader 323 and slides it to the left and right in Fig. 3 to change the ratio of combining the music data of CH1 and the music data of CH2. Can be adjusted. For example, when music crossfader 323 knob 325 (in other words, handle or knob) 1S knob 32 5 moves to the leftmost of the movable range, CH1 music data and CH2 music data are 100% : Synthesized at a ratio of 0%. That is, only the music data of CH1 is output to the external output device connected to the power mixer 3. After that, as the knob 325 of the music crossfader 323 moves to the left side and right side, the ratio of the music data of CH1 decreases and the ratio of the music data of CH2 increases. For example, when moving to the middle position of the movable range of the knob 325, the knob 325 of the music crossfader 323, the music data of CHI and the music data of CH2 are combined at a ratio of 50%: 50%. In other words, CHI music data and CH2 music data are combined at a ratio of 1: 1, and then output to an external output device connected to mixer 3. For example, when moving to the far right of the movable range of the knob 325 force knob 325 of the music crossfader 323, CH1 Music data and CH2 music data are combined at a ratio of 0%: 100%. In other words, only the music data of CH2 is output to the external output device connected to the mixer 3.

The video crossfader 324 constitutes a specific example of the “second operating element” in the present invention, and is composed of, for example, a touch pad 326. The video crossfader 324 is operated by the user to adjust the ratio of combining the CH1 video data and the CH2 video data. Specifically, in the same manner as when the knob 325 is slid in accordance with the movement of the user's finger moving on the surface of the touch pad 326 included in the video crossfader 324, the video data of CH1 and the CH2 The ratio of combining video data can be adjusted. In other words, the positional force of the finger that contacts the surface of the touch pad 326 provided in the video crossfader 324 corresponds to the position of the knob 325 described above. For example, when the user's finger is on the leftmost surface of the touchpad 326 of the video crossfader 324, the CH1 video data and the CH2 video data are combined at a ratio of 100%: 0%. That is, only the video data of CH1 is output to the external output device connected to the power mixer 3. Thereafter, as the user's finger moves toward the right side of the left side force on the surface of the touch pad 326 of the video crossfader 324, the ratio of the video data of CH1 decreases and the ratio of the video data of CH2 increases. For example, when the user's finger is on the surface near the intermediate position of the touch pad 326 of the video crossfader 324, the video data of CH1 and the video data of CH2 are combined at a ratio of 50%: 50%. In other words, CH1 video data and CH2 video data are combined at a ratio of 1: 1, and then output to an external output device connected to mixer 3. For example, when the user's finger is on the rightmost surface of the touch pad 326 of the video crossfader 324, the CH1 video data and the CH2 video data are combined at a ratio of 0%: 100%. In other words, only the video data of CH2 is output to the external output device connected to the mixer 3.

The effect rotary volume 331 is operated by the user in order to set the type of the video effect effect to be added to the video data. For example, a video effect effect that causes the video to blink periodically, a video effect effect that causes the video to periodically swell, and the like are set. Of course, various other video effect effects may be set. [0077] The effect rotary volume 332 is operated by the user in order to set a channel of video data to which a video effect is applied. In other words, it is operated by the user to select whether to apply the video effect effect to the CH1 video data or to apply the video effect effect to the CH2 video data.

[0078] The effect rotary volume 333 is operated by the user to set the first parameter indicating the degree of the video effect effect to be added to the video data (for example, the strength or periodicity of the effect outside the video effect). . For example, the first parameter may be set larger by rotating the effect rotary volume 333 clockwise. On the other hand, the first parameter may be set smaller by rotating the effect rotary volume 333 counterclockwise.

[0079] The effect rotary volume 334 is operated by the user to set the second parameter indicating the degree of the video effect effect to be added to the video data (for example, the intensity or periodicity of the effect outside the video effect). . For example, the second parameter may be set larger by rotating the effect rotary volume 334 clockwise. On the other hand, the second parameter may be set smaller by rotating the effect rotary volume 334 counterclockwise.

[0080] The effect ONZOFF switch 336 actually displays the video effect effect set by the effect rotary volume 331, the effect rotary volume 332, the effect rotary volume 333, and the effect rotary volume 334. It is operated by the user in order to instruct the timing to give to the data. When the effect ON / OFF switch 336 is pressed, the video effect set by the effect rotary volume 331, the effect rotary volume 332, the effect rotary volume 333, and the effect rotary volume 334 is changed. The video that is actually added to the video data and added with the video effect effect is displayed on the display.

[0081] The effect rotary volume 341 is operated by the user in order to set the type of the music effect effect to be added to the music data. For example, a music effect effect that produces a delay sound, a music effect effect that produces an echo sound, A music effect effect that generates an echo sound is set. Of course, other music effects can be set, of course.

The effect rotary volume 342 is operated by the user in order to set a channel of music data to which a music effect effect is applied. In other words, it is operated by the user to select whether to apply the music effect effect to the CH1 music data or to apply the music effect effect to the CH2 music data.

[0083] The effect rotary volume 343 is operated by the user to set a third parameter indicating the degree of the music effect effect to be added to the music data (for example, the intensity of the effect outside the music effect or the periodicity). . For example, the third parameter may be set larger by rotating the effect rotary volume 333 clockwise. On the other hand, the third parameter may be set smaller by rotating the effect rotary volume 333 counterclockwise.

[0084] The effect rotary volume 344 is operated by the user to set the fourth parameter indicating the degree of the music effect effect to be added to the music data (for example, the intensity or periodicity of the effect outside the music effect). . For example, the fourth parameter may be set larger by rotating the effect rotary volume 334 clockwise. On the other hand, the fourth parameter may be set smaller by rotating the effect rotary volume 334 counterclockwise.

[0085] The effect ONZOFF switch 346 actually reproduces the music effect set by the effect rotary volume 341, the effect rotary volume 342, the effect rotary volume 343, and the effect rotary volume 344. It is operated by the user in order to instruct the timing to give to the data. When the effect ON / OFF switch 346 is pressed, the music effect set by the effect rotary volume 341, the effect rotary volume 342, the effect rotary volume 343, and the effect rotary volume 344 is set. Actually attached to the music data, it flows from the music power speaker with the music effect effect.

[0086] The display unit 361 includes a liquid crystal display, for example, and displays an operation state in the mixer 3. For example, video data and music data input to the mixer 3 Information (for example, BPM, performance time, etc.), information on added video effects and music effects, etc. may be displayed.

[0087] Next, referring to FIG. 4, a perspective view conceptually showing how the music crossfader 323 and the video crossfader 324 included in the mixer 3 according to this embodiment are operated. It is.

[0088] As shown in FIG. 4, the user can hold the knob 325 of the music crossfader 323 using, for example, the thumb and middle finger.

On the other hand, the user can bring the index finger into contact with the surface of the touch pad 326 of the video crossfader 324 by extending the index finger that is not used to hold the knob 325. In other words, holding the knob 325 of the music crossfader 323 enables operation using the music crossfader 323, and at the same time, using the video crossfader 324 can be performed by extending the index finger. become.

As described above, according to the mixer 3 of the present embodiment, the user can compare the music crossfader 323 and the video crossfader 324 with the music cross as compared to the case where each of the music crossfader 323 and the video crossfader 324 includes the knob. There is no need to keep the fader 323 and the video crossfader 324 separately. As a result, the operability of the adjacent music cross-fader 323 and video cross-fader 324 can be improved.

In particular, the finger can be brought into contact with the surface of the touch pad 326 of the video crossfader 324 in accordance with the movement of sliding the knob 325 of the music crossfader 323. For example, if the knob 325 is slid by moving the lower left side force in FIG. 4 toward the upper right side while holding the knob 325, the extended index finger also contacts the surface of the touch pad 326 with the lower left side force toward the upper right side. Move while. Therefore, the user can operate the music crossfader 323 and the video crossfader 324 simultaneously or in the same movement relatively easily. Furthermore, since the video crossfader 324 does not have a knob, the user does not have to hold the two knobs forcibly. In other words, according to the present embodiment, when the knob 325 of the music crossfader 323 is held, the touchpad 326 of the video crossfader 324 is naturally or without any particular difficulty. You can touch your finger. For this reason, for example, the knob of the video crossfader is securely held. As a result, it is possible to suitably prevent the inconvenience in which only the music crossfader 323 is operated and the video crossfader 324 cannot be operated unintentionally.

On the other hand, each of the music crossfader 323 and the video crossfader 324 can be operated independently. At this time, since the touch pad 326 is a planar operator, the touch pad 326 does not interfere with the operation when the knob 325 of the music crossfader 323 is operated. In other words, since the video crossfader 324 does not have a knob, it is preferable that a finger or the like hits the knob of the video crossfader 324 when operating the knob 325 of the music crossfader 323. Can be prevented. Similarly, since it is sufficient to touch the touch pad 326 with a finger, the knob 325 located on the front side of the touch pad 326 does not interfere with the operation.

[0093] In addition, if the user touches the leftmost or right surface of the touchpad 326 of the video crossfader 324 (ie, the surface of the end of the touchpad 326), the video can be switched instantaneously. it can. Specifically, for example, when the video data of CH1 is being output from the mixer 3, if the user touches the surface on the right side of the touch pad 326, the video data output from the mixer 3 is Switch to CH2 video data instantly. On the other hand, for example, when CH2 video data is being output from the mixer 3, if the user touches the surface on the left side of the touch pad 326, the video data output from the mixer 3 will be the video data CH1 video data. Can be instantly switched to.

In the above-described embodiment, an example in which the flat touch pad 326 is applied to the video crossfader 324 has been described, but it goes without saying that the present invention is not limited to this. For example, a flat touch pad may be applied to one of the slide faders 321 and 322. Alternatively, with respect to other operators such as a fader, an operator having a knob or the like is applied to one of the adjacent operators, and an operator having a flat touch pad or the like to the other of the adjacent operators. May be configured to apply.

In addition to the mixer 3, for example, the above-described configuration may be applied to the optical disc playback apparatus 2, or the above-described configuration may be applied to various information devices including adjacent operators. May be. In this case, it is preferable that the operation element is a fader that can move in the longitudinal direction (vertical direction) or the horizontal direction (lateral direction). However, it may be a fader that slides in a curved line, for example, without sliding in a straight line.

[0096] Further, for example, a touch panel may be used as the planar operation element instead of the touch pad 326. Alternatively, other planar operation elements may be used.

[0097] Next, a mixer 4 according to a modification will be described with reference to FIGS. Here, FIG. 5 is a plan view conceptually showing the basic external configuration of the mixer 4 according to the modification, and FIG. 6 is a music crossfader 323 and video for the mixer 4 according to the modification. FIG. 5 is a perspective view conceptually showing a state when each of the crossfaders 324 is operated.

Note that the same components as those of the mixer 3 described with reference to FIGS. 1 to 4 are denoted by the same reference numerals, and detailed description thereof is omitted.

[0099] As shown in FIG. 5, the mixer 4 according to the modified example is similar to the mixer 3 described above, and includes an input terminal 301, an input terminal 302, an equalizer rotary volume 311, and an equalizer rotary volume 312. , Equalizer rotary volume 313, Equalizer rotary volume 314, Equalizer rotary volume 315, Equalizer rotary volume 316, Slide fader 321, Slide fader 322, Music crossfader 323 , Video crossfader 324, effect rotary volume 331, effect rotary volume 332, effect rotary volume 333, effect rotary volume 334, effect ONZOFF switch 336, and effect rotary A volume 341, and the effect for rotary volume 342, and the effect for a rotary volume 343, and the effect for rotary volume 3 44, and the effect ONZOFF switch 346, and a display unit 361.

[0100] The mixer 4 according to the modification particularly includes a position display unit 327. The position display unit 327 constitutes a specific example of the “display unit” in the present invention, and the current position of the user's finger moving on the surface of the touch pad 326 included in the video crossfader 324 is displayed on the LED. Illustrated by lighting. The position display unit 327 is preferably configured by arranging a plurality of LEDs along the sliding movement direction of the knob 325 and by the same length as the touch pad 326. Specifically, as shown in FIG. 6, the LED 327a corresponding to the current position of the user's finger moving on the surface of the touch pad 326 is turned on. As the user's finger moves on the surface of the touchpad 326 of the video crossfader 324 with the left side force on the right side, the LED to be lit also moves with the left side force on the right side. The LED continues to light even when the user's finger touch S touch pad 326 is disengaged. That is, the LED corresponding to the position on the touch pad 326 where the user's finger last touched continues to be lit.

[0102] In other words, when it is assumed that the video crossfader 324 has a knob, the LED corresponding to the position of the knob is turned on.

[0103] This allows the user to determine what force the user is using with the touchpad 326, and where the touchpad 326 has the knob, assuming that the video crossfader 324 has a knob. Or the like can be visually recognized.

Note that the position display unit 327 does not necessarily include an LED. For example, a liquid crystal panel that extends along the direction of sliding movement of the knob 325 and has the same length as that of the tactinod 326 may be provided. In this case, the liquid crystal panel corresponds to the current position of the user's finger moving on the surface of the touch pad 326 included in the video crossfader 324 (or the position on the touch pad 326 where the user's finger last touched). Give the position some indication that can be distinguished from other parts. In short, the current position of the user's finger moving on the surface of the touch pad 326 included in the video crossfader 324 (or the position on the touch pad 326 where the user's finger last touched) is visually indicated to the user. Any means that can be recognized can be used in addition to or instead of the LED.

[0105] The present invention is not limited to the above-described embodiments, but can be appropriately modified within the scope of the claims and the entire specification without departing from the gist or idea of the invention which can be read. Operation panels and information devices are also included in the technical scope of the present invention.
