Description

  The present invention relates to a parameter setting device that sets parameters by operating an operator, and more particularly to a parameter setting device suitable for providing a single operator with a function of setting a plurality of parameters.

  Conventionally, mixing consoles are used in broadcasting stations, recording studios, concert venues, etc., and output various audio signals such as musical instruments and vocals as monitors for players and monitors for mixers. Various controls (signal processing) need to be performed. For this reason, a large number of various operators are arranged on the operation panel, but it is required to improve the operability of the operation panel and reduce the burden on the operator.

  For example, Japanese Patent Laid-Open No. 9-198953 discloses a technique in which a plurality of fader knobs are made different in color such as red, green, and yellow, and the positions of the fader knobs are identified by identifying the colors. It is disclosed. In this way, if the operating elements can be visually identified by color, the burden on the operator can be reduced when operating a large number of operating elements.

  Also, along with the digitization of such a mixing console, input level adjustment, master output adjustment, send level adjustment, or graphic equalizer for one slide volume or a set of slide volumes There are an increasing number of specifications that combine various functions, such as for setting filter characteristics for considerable frequencies.

In the field of electronic musical instruments, it is also widely used to set the tone using the draw bar (slide volume) and to set the musical sound parameters such as volume before and during the performance using the slide-type controller (slide volume). A slide volume is used as the volume on the operation panel. It is also conceivable to transfer such a volume to a plurality of parameter settings.
JP-A-9-198953

  As described above, when one slide volume or a set of slide volumes has a plurality of functions, it is necessary to know what function the slide volume is set to. However, in the conventional technique, the fader picking color is fixed, and it is impossible to grasp the set function.

  It is an object of the present invention to provide a parameter setting device having a structure in which a function set in an operator can be grasped intuitively and easily in a parameter setting device that sets a parameter by operating the operator.

In the parameter setting device according to the first aspect, the operating element moves the moving unit relative to the fixed unit, thereby changing and setting the parameter. A light emitting unit having a multi-color light emitting element is provided on the upper part of the moving unit so that the function set for the operation element in the light emitting unit can be easily identified by the emission color. At this time, the light emitting unit is driven with a color corresponding to the selected function by a table in which a plurality of functions and colors are defined .

In addition to claim 1 , the parameter setting device according to claim 2 forms the detection pattern and the power feeding pattern on one side surface of the movement guide, and the movement with respect to the movement guide that slides and holds the moving portion via the detection pattern. In addition to detecting the movement signal of the part and performing the energization process of the light emitting part via the power feeding pattern , for example, when the sensor is a contact type consisting of a sliding body, the energization part is combined into one in the movement guide Therefore, the device configuration is simplified. As a common energization process, for example, when the sensor is a contact type composed of a sliding body, a sliding energization part is provided in the “moving guide”, and the sensor and the multicolor light emitting element are energized in common through this. To do. When the sensor is not in contact, the sensor and the multicolor light emitting element are energized in close proximity or in common via a lead wire connected to the “moving part”.

In addition to claim 2 , the parameter setting device according to claim 3 detects the movement signal of the moving unit by contacting the detection pattern or the power feeding pattern with the brush contact of the operation element using the side surface of the movement guide as the sliding surface. In addition, the energization process of the light emitting unit was performed.

According to the parameter setting device of the first aspect, in the parameter setting device for setting the parameter by operating the operation element, the function and the color are defined in the table, so that the function set in the operation element by the light emitting unit is changed to the emission color. Since the currently selected function can be intuitively grasped by color, it can be quickly operated and the operability is improved .

According to the parameter setting device of claim 2, as in claim 1, since the currently selected function can be intuitively grasped by color, quick operation can be performed and operability is improved, and one of the movement guides is improved . Since the detection pattern and the power feeding pattern are formed on the side surfaces and the energization parts can be combined into one, the device configuration is simplified.

According to the parameter setting device of the third aspect, the same effect as the second aspect can be obtained.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 8 is an overall view of the panel surface 100 of the mixing console using the slide volume device of the embodiment. In the description of the panel surface 100, directions are shown in the up, down, left, and right directions when the panel surface 100 is viewed from the front. The panel surface 100 includes a volume controller 50 for adjusting the input level of a monaural input channel such as a microphone input or a line input, a channel-on switch operation button 60, a liquid crystal display 70 for displaying input channel installation contents, and the like. A group of slide operators 80 including a plurality of slide operators 61 corresponding to each of the plurality of slide volume devices is provided.

  For example, the slide operator group 80 operates as a graphic equalizer to set frequency characteristics of input signals and output signals, sets parameters corresponding to filter characteristics, and sets input and output levels. Used to set various parameters such as setting parameters as faders to be adjusted. That is, many parameters can be set by selecting and switching the functions of the slide operator group 80 from a plurality of functions. Then, as will be described in detail later, the function currently selected for the slide operator 61 can be confirmed by the light emission color of the light emitting portion of the slide operator 61.

  FIG. 2 is an exploded perspective view of the main part showing an embodiment of the slide volume device. In this slide volume device, side plates 31A and 31B that form a right angle surface on the back side with respect to the panel surface 100 and two U-shaped frames 31Cu and 31Cd in which two U-shaped directions Z and Y are orthogonal to each other. As a result, a frame 31 as a “fixed portion” is formed. The frame 31Cd is attached so as to surround the upper ends and both ends of the side plates 31A and 31B from above, and the frame 31Cu is attached on the frame 31Cd. Then, while the motor 32 is attached to one end of the upper frame 31Cu, the entire frame 31 is attached to the back surface of the front panel 100 by the fasteners 31a and 31b on both sides of the upper frame 31Cu. The side plate 31B is formed with a lead wire outlet 311 for pulling out a flat cable 91 applied to a non-contact type slide volume device described later. A first moving guide 41 and a second moving guide 42 that are parallel to each other along the longitudinal direction X of the side plate 31A are spanned between the end surfaces 31c and 31d at both ends of the lower frame 31Cd. It has been. The first movement guide 41 is a round bar-shaped metal member, and the second movement guide 42 is a square bar-shaped metal member. The first and second movement guides 41 and 42 include a part of the “moving portion”. A moving block 51 is attached so as to be slidable in the longitudinal direction of the moving guides 41, 42.

  A drive pulley 32a is attached to the drive shaft of the motor 32 disposed on one side of the frame 31Cu, and a driven pulley 32b is disposed on the other end of the frame 31Cu. A timing belt 32c is wound around the driving pulley 32a and the driven pulley 32b, and an upper portion of the moving block 51 is attached to one position of the timing belt 32c. As a result, the moving block 51 reciprocates along the first and second moving guides 41 and 42 by forward and reverse rotation of the motor 32. This is, for example, an operation for automatically setting the position of the slide operation element 61 so as to correspond to the parameter when another channel is assigned to the slide volume device (fader) or another function is assigned. .

  FIG. 1 is a perspective view of a main part of the moving block 51, and shows a state seen from the direction of the arrow P in FIG. The moving block 51 is formed with a shaft hole 51 a into which the first moving guide 41 is inserted and shaft holes 51 b and 51 b into which the second moving guide 42 is inserted, and is further away from the second moving guide 42. Thus, the board | substrate accommodating part 51c is formed as a surface depressed rather than the shaft holes 51b and 51b. A substrate 52 is fixed to the substrate accommodating portion 51c, and brush contacts 52a, 52b, 52c, and 52d formed of a conductive member having elasticity are attached to the substrate 52. Further, the three brush contacts 52a, 52b, 52c are connected to conducting wires 52a1, 52b1, 52c1, and these conducting wires 52a1, 52b1, 52c1 serve as “multicolor light emitting elements” attached to the lever 53 through the through holes 51d. The multicolor LED element 54 is connected. As shown in FIG. 2, a slide operator 61 having a light guide 61 a facing the upper light emitting surface of the multicolor LED element 54 is attached to the lever 53. In this embodiment, the moving block 51 and the lever 53 constitute a “moving part”. In addition, the multicolor LED element 54 and the light guide 61a constitute a “light emitting portion”.

  Further, as shown in the two-dot chain line blowing portion in the lower part of FIG. 1 with the left and right reversed with respect to the upper figure, the LED lead pattern 42a, which contacts the brush contacts 52a, 52b, 52c, respectively, on the side surface of the moving guide 42, 42b and 42c, and the conductive wire pattern 42d and the volume resistance pattern 42e that are in common contact with the brush contact 52d are formed over the entire length in the longitudinal direction of the moving guide 42, respectively. The LED conductor patterns 42a, 42b, 42c and the conductor pattern 42d are conductors having substantially zero resistance, and are connected to a circuit (not shown), and brush contacts 52a, 52b, 52c that are always in contact with the LED conductor patterns 42a, 42b, 42c are provided. A driving current is supplied to the multicolor LED element 54 through the multi-color LED element 54. 1, the multicolor LED element 54 is composed of a red LED 54a and a green LED 54b, and the common line 541 is an LED lead pattern via a lead 52a1 and a brush contact 52a. The single wires 54a1 and 54b1 are connected to the LED lead patterns 42b and 42c through the lead wires 52b1 and 52c1 and the brush contacts 52b and 52c, respectively.

  The volume resistance pattern 42e has a predetermined resistance value per unit length, and one ends of the volume resistance pattern 42e and the conductive wire pattern 42d are connected to a voltage detection circuit (not shown). The volume resistance pattern 42e and the conductive wire pattern 42d are always short-circuited at the position of the brush contact 52d by the brush contact 52d, and depending on the distance from the end on the voltage detection circuit side to the position of the brush contact 52d, It functions as a later-described volume circuit V1 indicating the resistance value (see FIG. 3). Accordingly, the position of the brush contact 52d with respect to the second movement guide 42, that is, the position of the slide operation element 61 is detected by the voltage detection circuit. In this embodiment, the volume resistance pattern 42e and the brush contact 52d constitute a contact type “sensor”.

  As described above, the energization process for the multi-color LED element 54 and the energization process for the volume resistance patterns 42d and 42e and the brush contact 52d are performed in common using the side surface of the movement guide 42. Therefore, the conducting portions can be combined into one, and the device configuration is simplified.

  FIG. 3 is a circuit diagram of a parameter setting device using the slide volume device. This circuit is a circuit for switching and setting the slide volume device to a plurality of (three in this example) different functions, and includes switch circuits c1, c2, c3 and selector circuits d1, d2 interlocked with a function selection switch (not shown). Yes. FIG. 3 shows a circuit corresponding to one slide volume device, but the same applies to a plurality of slide volume devices corresponding to the plurality of operators 61 of the slide operator group 80. The same function selected by the function selection switch is set in the other slide volume devices. Hereinafter, one slide volume device will be described.

  One ends of the switch circuits c1, c2, and c3 are grounded (earthed), and the other ends are connected to the selection terminals d11, d12, and d13 of the selector circuit d1, respectively. The volume circuit V1 of the slide volume device is connected between the common contacts of the selector circuits d1 and d2. The selection terminals d21, d22, d23 of the selector circuit d2 are connected in parallel to the reference voltage and the utilization circuit 200. The signal lines d3, d4, and d5 connected in parallel to the utilization circuit 200 respectively send voltage signals to required locations in the utilization circuit 200 according to the functions (1), (2), and (3). It is supplied as a parameter. Further, one end of the red LED 54a and the green LED 54b of the multicolor LED element 54 is connected to a reference voltage, and the other end is grounded via resistors r1 and r2 and switch circuits c1 and c2, respectively, and resistors r3 and r4. Are commonly grounded via the switch circuit c3. Resistors r to r4 are current limiting resistors for the LED.

  When the function (1) is selected, the switch circuit c1 is turned on (closed), and the selection terminal d11 of the selector d1 and the selection terminal d21 of the selector d2 are connected to the volume circuit V1, respectively. When the function (2) is selected, the switch circuit c2 is turned on (closed), and the selection terminal d12 of the selector d1 and the selection terminal d22 of the selector d2 are connected to the volume circuit V1, respectively. Further, when the function (3) is selected, the switch circuit c3 is turned on (closed), and the selection terminal d13 of the selector d1 and the selection terminal d23 of the selector d2 are connected to the volume circuit V1, respectively. Accordingly, a voltage signal corresponding to the resistance value of the volume circuit V1 is generated by the operation of the slide volume device. This voltage signal is changed from the signal line d3 in the function (1) to the signal line d4 in the function (2). To the utilization circuit 200 from the signal line d5 at the time of function (3).

Further, only the red LED 54a is lit when function (1), and only the green LED 54b is lit when function (2). In the case of function (3), both the red LED 54a and the green LED 54b are lit. As a result, the light guide 61a of the slide operation element 61 emits "red" when function (1), "green" when function (2), and "yellow (red + green)" when function (3). It is possible to easily confirm which function is currently selected by the light emission color of the light guide 61a .

  In the above embodiment, the case where the multi-color LED element 54 is two LEDs of the red LED 54a and the green LED 54b has been described. . In this case, by controlling the luminance of each LED, it is possible to develop colors with many colors, which is suitable for selecting a large number of functions. FIG. 4 is a circuit diagram of the parameter setting device when a large number of functions are selected. Switch circuits s1, s2,..., Sn corresponding to a plurality of operators (not shown) for selecting functions are connected in parallel to the reference voltage V. The ON signals of these switch circuits s1, s2,. The OFF signal becomes an L level signal, and these ON / OFF signals are input to the selector b1 and the table b2 as bit signals of a plurality of bits. The switch circuits s1, s2,..., Sn are alternatively turned on by the corresponding operators, and one bit of this bit signal is at the H level and the other bits are at the L level.

  The volume circuit V1 driven by the slide volume device is connected to the reference voltage V, and a voltage signal corresponding to the resistance value of the volume circuit V1 is input to the selector b1. The outputs e1, e2,..., En of the selector b1 correspond to the switch circuits s1, s2,..., Sn, respectively, and this selector b1 outputs e1, e.g. by the bit signals from the switch circuits s1, s2,. Alternatively, e2,..., en are selected, and the voltage signal of the volume circuit V1 corresponding to each function is supplied to the utilization circuit 200.

  On the other hand, the table b2 is a circuit that converts a bit signal input from the switch circuits s1, s2,..., Sn into, for example, three bit signals composed of 3 bits, and the three bit signals output are the switch circuit s1. , S2,..., Sn is a bit signal representing the color assigned to the function selected. The three bit signals of 3 bits are supplied to electronic volume circuits va, vb, and vc that control supply currents to the red LED 54a, green LED 54b, and blue LED 54c, respectively. Thereby, the red LED 54a, the green LED 54b, and the blue LED 54c emit light with the luminance indicated by the corresponding bit signals. In this example, each bit signal is numeric data corresponding to the luminance of “0 to 7” in 3 bits, and is not lit (black) by combining the luminance of the three colors of the red LED 54a, the green LED 54b, and the blue LED 54c. Can emit light in 512 colors.

  The above slide volume device is an example of a contact type, but FIG. 5 is a perspective view of an essential part showing another embodiment of a non-contact type slide volume device. The difference between this embodiment and the embodiment of FIG. 1 is that a magnetic sensor 71 is mounted on a substrate 52 'on a moving block 51', and a magnetic pole pattern M is formed on the first moving guide 41 '. And the point that the flat cable 91 is connected to the substrate 52 ′, and other configurations are substantially the same as those in FIGS. 1 and 2. Accordingly, in FIG. 5, the main part is shown, and the elements corresponding to the elements of the embodiment of FIG.

  In this embodiment, both the first and second moving guides 41 'and 42' are round bar-shaped metal members, and a part of the "moving part" is added to the first and second moving guides 41 'and 42'. Is mounted so as to be slidable in the longitudinal direction of the movement guides 41 'and 42'. Also in this embodiment, the frame 31 composed of the side plates 31A and 31B and the frames 31Cu and 31Cd is a “fixed portion”. In addition, the moving block 51 ′ has a rectangular space (hole) S formed at the center of the upper guide holding portion 5a. The space S facilitates the formation of the moving block 51 ′. It does not have to be.

  As shown in part in the two-dot chain line blowing portion in FIG. 5, holding holes 5a1 penetrating the space S are formed at both ends of the guide holding portion 5a, and holding rings 51a 'and 51a are formed in the holding holes 5a1. 'Is attached. A substrate holding portion 51c ′ is provided below the lower side of the guide holding portion 5a. A holding hole 5b1 is formed in the guide holding portion 5b on the lower side of the substrate holding portion 51c ′ and is held in the holding hole. A ring 51b 'is attached. The first moving guide 41 ′ is fitted and inserted so as to penetrate the guide holding portion 5 a through the holding wheels 51 a ′ and 51 a ′ and the space S. The second moving guide 42 'is fitted and inserted so as to penetrate the guide holding portion 5b via the holding ring 51b'. The inner surfaces of the holding wheels 51a ', 51a', 51b 'are smoothly finished, and move smoothly when the moving block 51' moves along the moving guides 41 ', 42'.

  A substrate 52 'is attached to the substrate holding part 51c', and a magnetic sensor 71 is attached to the substrate 52 '. Further, one end of a flat cable 91 is connected to the substrate 52 'via a terminal portion 91a, and conductive wires 52a1', 52b1 ', and 52c1' are connected. LED holding portions 5d1 and 5d2 having different upper and lower steps are formed on the upper end of the lever 53 '. The LED holding portions 5d1 and 5d2 are provided with multicolor LED elements 54' as "multicolor light emitting elements". It is attached. The conducting wires 52a1 ', 52b1', 52c1 'are adhesively locked to the recesses 5a2, 5a3 provided in the opposing part for the frame 31A of the guide holding part 5a with a rubber adhesive (can be pulled off if pulled) to hold the LED It is led to the part 5d2 and connected to the multicolor LED element 54 '. The lever 53 'is attached with a slide operator 61' having a light guide 61a 'facing the upper light emitting surface of the multicolor LED element 54'. In this embodiment, the moving block 51 ′ and the lever 53 ′ constitute a “moving part”. Further, the multicolor LED element 54 'and the light guide 61a' constitute a "light emitting part". The light guide 61a 'may be omitted, and the multicolor LED element 54' may be exposed as it is.

  A magnetic sensor 71 (or MR sensor) formed of an IC or the like including a Hall element is mounted on the substrate 52 '. The sensing surface of the magnetic sensor 71 is relative to the first moving guide 41'. They face each other with a slight gap (interval). Further, the output line of the magnetic sensor 71 and the conducting wires 52a1 ', 52b1', 52c1 'of the multicolor LED element 54' are connected to the outside through a flat cable 91 attached to the substrate 52 '. . The multi-color LED 54 ′ emits light by the current supplied from the flat cable 91. In addition, the magnetic sensor 71 is energized via the flat cable 91, and a detection signal described later of the magnetic sensor 71 is sent to a circuit (not shown) via the flat cable 91.

  The first moving guide 41 'is manufactured from an alloy in which iron is used as a base material and nickel and cobalt are mixed. As a result, the first moving guide 41 ′ can retain the properties of the iron itself as it is, is not easily broken, and has a spring property that returns to its original state even if it is slightly bent. That is, the moving guide 41 'is less likely to be broken even when a pressing force is applied, and the apparatus can be prevented from being broken, rather than using a ferrite magnet itself that is easily broken.

  Furthermore, as shown in FIG. 6, the first moving guide 41 'is a magnet in which a number of magnetic poles are formed by alternately and finely polarizing N poles and S poles in the longitudinal direction. For example, the magnetic pole is a high-resolution magnet having a pitch of 100 μm between the N and N poles (50 μm between the N and S poles). The magnetic sensor 71 is formed by an IC or the like including a Hall element (or MR sensor), and the sensing surface 71a of the magnetic sensor 71 is formed on the magnetic pole surface 41a 'of the first moving guide 41'. For example, a slight clearance CR (interval) of about 0.1 to 0.2 mm is provided to face each other. And the magnetic field of this magnetic pole surface 41a 'is detected by the magnetic sensor 71, and a detection signal is obtained.

  That is, when the magnetic sensor 71 moves with respect to the magnetic pole surface 41a 'of the movement guide 41' as the moving block 51 'moves, the magnetic sensor 71 detects the polarity of the N pole and the S pole of the magnetic pole surface 41a'. A pulse signal corresponding to the inversion of is output. The moving amount (length) of the moving block 51 ′ can be detected from the number of pulse signals. The magnetic poles of the magnetic pole surface 41a 'are composed of, for example, two rows, the phase of which is shifted in the longitudinal direction of the pattern moving guide 41' of the magnetic poles by 1 / 2π, and the magnetic sensor 71 outputs a pulse signal having a phase shift. Since the data is output, the moving direction of the moving block 51 'is determined by the opposite direction of the phase shift. Alternatively, the magnetic pole pattern is composed of an NSNS... Pattern having no phase shift, and the detection pole portion of the sensor may be arranged with a shift corresponding to 1 / 2π. Further, since the position information of the position before the movement of the moving block 51 ′ is always stored by a control circuit (not shown) or the like, the moving block 51 in the entire slide volume device is determined based on this position information, the moving amount and the moving direction. The position of ', that is, the position of the slide operator 61' is detected.

  When the slide block 61 'is manually operated to move (slide) the moving block 51', the moving block 51 'is generally pressurized in the direction indicated by the arrow Q in FIG. On the other hand, the magnetic sensor 71 senses the moving guide 41 ′ itself that holds the moving block 51 ′ provided with the magnetic sensor 71. Therefore, even if the movement guide 41 'is slightly bent due to a strong pressure and the movement block 51' is lowered, the clearance CR is always constant, so that the influence on the detection accuracy due to the pressure can be eliminated. When the clearance as described above fluctuates, the level of the detection signal changes and the detection accuracy decreases, but this does not occur according to the above embodiment.

  Further, as indicated by the dotted line in FIG. 6, the magnetic pole of the moving guide 41 ′ is formed such that the magnetic pole surface 41a ′ exhibits stronger magnetization than the inside of the moving guide 41 ′. The size may be small. That is, since the clearance CR is constant, the clearance CR itself can be reduced. Therefore, if the sensitivity of the magnetic sensor 71 is set to the same sensitivity as when the clearance is increased, the magnetization itself may be weaker than when the clearance is increased. That is, the magnetization intensity of the magnetic pole surface 41a ′ may be small. The intensity of this magnetization is only required to be magnetized to a minimum magnetic force so that there is no dead zone or non-operating zone of sensing by the magnetic sensor 71 and the magnetic pole surface 41a 'during normal pressure or normal operation. Stable sensing can be obtained even when a strong pressure is applied. In this way, the clearance CR is made small to improve sensitivity and detection accuracy. Note that even if the clearance between the second moving guide 42 'and the moving block 51' is large, the sensitivity and accuracy are not affected. Therefore, the clearance may be designed somewhat rough and the cost can be reduced.

  FIG. 7 is a sectional view showing a modification of the movement guide. The moving guide 41 'in the above embodiment is in the shape of a round bar shown in (I). (II) is an oval bar shape with a flat cross section, (III) is a square bar shape with a square cross section, (IV) is a long plate shape with a vertical cross section, (V ) Shows a long plate shape whose cross section is a horizontal rectangle. The moving block is provided with a holding hole that matches the cross-sectional shape of these moving guides, but in the case of (IV) and (V), only one moving guide may be provided. In other words, the second movement guide 42 'plays an auxiliary role to prevent the movement block 51' from rotating (rolling) around the first movement guide 41 '. However, in the case of the above (IV) and (V), the rotation of the moving block can be suppressed by only one moving guide, and the second moving guide 42 'and the like are not required.

  The first moving guide 41 'is made of an alloy in which iron is used as a base material and nickel and cobalt are mixed, so it is also a moving guide that is not easily broken. You may make it form. In this way, any of (II) to (V) shown in FIG. 7 can be easily made. For example, since the magnetization method only needs to magnetize only the surface facing the magnetic sensor, the lower farite magnet does not decrease in magnetic force due to bonding. For example, the moving guide 41 'is magnetized only in the lower 3%, and the upper surface has almost no magnetic force.

  In the second embodiment, the lower guide holding portion 5b and the holding wheel 51b 'of the moving block 51' are configured to fit over the entire circumference of the second moving guide 42 '. Even if either one of the left and right sides of the guide holding portion 5b (and the holding wheel 51b ') is open with respect to the moving guide 42', the moving guide 42 'may come off the guide holding portion 5b because of the side plate. Absent. Moreover, the lower part of the guide holding | maintenance part 5b (and holding wheel 51b ') may be open | released. This facilitates assembly. Further, the holding guide 51b ′ may not be provided in the lower guide holding portion 5b.

  In addition, since the magnetic detection is performed as in the above-described embodiment, the detection accuracy is reduced even if the sensing surface of the magnetic sensor 71 and the magnetic surface 41a 'become dirty or dust enters the clearance portion. And a slide volume device that is resistant to dirt and dust can be obtained.

  As described above, the energization process for the multi-color LED element 54 ′ and the energization process for the magnetic sensor 71 (and signal derivation) are performed in common by the flat cable 91. Therefore, the conducting portions can be combined into one, and the device configuration is simplified.

  As shown in FIG. 2, the side plate 31B has a vertically long lead wire outlet 311 formed at the center in the moving direction of the moving block 51 '(the center in the longitudinal direction of the side plate 31B). The flat cable 91 connected to the magnetic sensor 71 and the multi-color LED element 54 'is pulled out from the substrate 52' and turned back by 180 °, and further drawn out from the lead wire outlet 311 to the outside of the side plate 31B. That is, since the lead wire outlet 311 is in the center, the length of the portion inside the flat cable 91 from the lead wire outlet 311 may be approximately half of the entire sliding range of the moving block 51 ′, and it is folded back. Therefore, the flat cable 91 can be easily accommodated in the case 31. Therefore, the flat cable 91 can be lightly fixed at the lead wire outlet 311. Even if the moving block 51 'moves, the flat cable 91 is connected to the head of a normal printer as viewed from the outside of the side plate 31B. Since it does not dangle like a cable, the fit of the slide volume device in the device is improved.

  The above embodiment is an example in which a non-contact type is realized by a magnetic method, but may be a non-contact type by an optical method. In this case, for example, in the example of FIG. 5, for example, two rows of black and white barcode-like patterns with a constant period are formed on the lower surface (the surface corresponding to the magnetic surface 41 a ′) of the first moving guide 41 ′. Instead, a photosensor composed of a light emitting diode and a photodiode is provided, and a pulse signal having the phase difference corresponding to the two rows by the black and white pattern is obtained as a detection signal. Also in this optical type, the flat cable 91 is used for energizing the multicolor LED element 54 ′ and energizing the photo sensor. Also in this case, since the first movement guide 41 'itself is sensed by the photosensor even if a pressure is generated, the clearance (gap) between the photosensor and the pattern surface can be kept constant. As with the magnetic type, detection accuracy is ensured.

  In either case of the magnetic type or the optical type, the guide holding part 5a works as a stopper in the pressing direction (arrow Q direction) at the time of operation, and the position of the moving block 51 'in the pressing direction with respect to the moving guide 41' is changed. Since each is regulated to be constant, the operational feeling (sliding feeling) is improved, and measures against vertical load are also taken for the entire apparatus.

  The circuit diagram of the parameter setting device using the above-described magnetic and optical non-contact type slide volume device is also the same as that shown in FIGS. However, in these embodiments, the volume circuit V1 in FIGS. 3 and 4 is an electronic volume whose resistance is set according to a detection signal obtained by the magnetic sensor 71 or the photosensor in the slide volume device. Then, it is possible to easily confirm which function is currently selected for the slide volume device among a plurality of functions, based on the emission colors of the multi-color LED element 54 ′ and the light guide 61 a ′.

  In the above embodiment, the example in which the acoustic parameters are set by the mixing console has been described. However, in other devices, when a plurality of parameters are set, the operator can be identified by color corresponding to the function. be able to.
