Abstract

<P>PROBLEM TO BE SOLVED: To make an adjusting device using a fader device such as a mixer device, which speedily performs startup processing when a main power source is turned on. <P>SOLUTION: The main power source is turned off in different modes with an A switch 87, a B switch 88, and a C switch 89. When the main power source is turned off and on with the A switch 89, initialization processing for an operation value position is performed. When the main power source is turned off by operating the B switch 88 or C switch 89, the operation of an operator 6 of the fader device 10 is monitored even in a power-off state. When the main power source is turned on with the B switch 88, the operator 6 is corrected to the position right before the power source is turned off by a displacement quantity thereof when the operator 6 is operated during the power-off operation. When the main power source is turned on with the C switch 89, a parameter value is corrected by the displacement quantity of the operator 6 when the operator 6 is operated during the power-off operation, and the position of the operator 6 is not corrected. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention provides an incremental encoding type slide operation device that detects the position of an operator by detecting markings such as a magnetic pole pattern and a light and shade pattern on a linear scale by a sensor unit that moves along the linear scale. The present invention relates to a slide type signal conditioner used.

  Conventionally, a slide operation device has been used as a fader device for setting various parameter values in a mixing console, for example, and there is one disclosed in Japanese Patent Laid-Open No. 2003-21541 (Patent Document 1).

The thing of this patent document 1 is a non-contact digital fader, and this fader device uses the manual operation of the operating element or the driving of the motor to move the shading pattern recorded on the linear scale when the operating element (or moving member) moves. The position is read by an optical sensor, the pulse signal associated with the movement of the operation element is counted, and the position on the linear scale is calculated. Then, various parameter values (signal values) of functions assigned to the fader device are used by setting them to values corresponding to the position of the operation element.
JP 2003-21541 A

  By the way, in a mixing console using such a fader device, for example, various parameter values set by the fader device are stored when the power is turned off. Is returned to the position immediately before the power is turned off (operation element position initialization process). This eliminates the fact that it is extremely difficult to return to the same setting state (that is, the same scene) by manual operation, especially when many parameter values are set by a large number of fader devices.

  However, in the case of a fader device that counts pulse signals, that is, an incremental-encode slide operation device, the device cannot recognize the relative position of the operator with respect to the linear scale when the power is turned on. Therefore, the operator is temporarily moved to, for example, the end of the linear scale (reference position, etc.), the pulse signal is counted while moving the operator from the position to the opposite side, and this count value is stored in the set value. It is necessary to align the position of the operator so as to correspond. For this reason, there is a problem that a waiting time is required at the time of restarting when power is turned on, which is inconvenient for the user. Moreover, since many motors are driven at a time for a relatively long time, there is a problem that a large load is applied.

  It is an object of the present invention to reduce waiting time and load when power is turned on again in a slide type signal adjustment device (for example, a mixing console) using an incremental encoding type slide operation device. To do.

  The slide type signal adjustment device according to claim 1 monitors the operation of the operation element of the slide operation device even when the main power supply is cut off by the power off function. Thus, when the main power supply is turned on, the position of the operation element is corrected by the amount of variation, and the operation element position is not initialized when there is no operation of the operation element with the main power supply turned off.

  According to a second aspect of the present invention, there is provided a slide type signal conditioning apparatus according to the first aspect, further comprising a start-up subfunction, wherein the start-up subfunction does not perform initialization processing of the operator position when the main power is turned on. When the operation of the operating element is detected in a state in which is disconnected, the signal value assigned to the slide operating device is corrected according to the variation amount of the position of the operating element. Further, either one of the start-up subfunction and the start-up function for correcting the fluctuation amount of the operation element can be selected.

  It is to be noted that the present invention further includes an all-off function for turning off the main power supply and always initializing the operator position when the main power is turned on. Instead of the raising function and the startup sub-function, selection may be made. In this case, the power-off function, the start-up function, and the start-up sub function may be unilaterally switched to this all-off function.

  The initialization process of the operator position may be a process in which the operator is moved to a position corresponding to the stored signal value after the operator is moved to the reference position.

  The slide operation device may be a magnetic type that detects a magnetic pole pattern of a linear scale with a magnetic sensor, or an optical type that optically detects a shade pattern of the linear scale such as black and white.

  According to the slide type signal conditioner of claim 1, the amount of change is corrected only when the operating element is operated in a state where the main power is cut off, and when the operating element is not operated, the initialization process of the operating element position is performed. Therefore, it is possible to quickly restart the system when the power is turned on, and to reduce the load of driving the motor. Further, even when the operation is performed, it is not an initialization process of the operation element position, but only the fluctuation amount is corrected, and the time and the load can be reduced.

  According to the slide type signal adjustment device of the second aspect, in addition to the effect of the first aspect, the change of the parameter value or the like is performed by operating the operation element in a state where the main power supply is turned off by the user's selection. You can also.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of a main part of a digital mixer as a slide type signal conditioning apparatus of the embodiment, FIG. 2 is a front view of a main part of a panel surface of the digital mixer, and FIG. FIG. In the description of the panel surface 100 in FIG. 2, directions are shown vertically and horizontally when the panel surface 100 is viewed from the front. FIG. 2 illustrates a portion corresponding to an input channel such as a microphone input or a line input, and a plurality of operation elements are provided side by side in the left-right direction with one channel vertically. Each channel includes a pan adjustment operator 81, a selector operator 82, a display screen 83, a valid / invalid setting operator 84, an operator 6, and a test listening switch 85. Further, a display changeover switch 86 for switching the display of the display screen 83 is provided.

  The operation element 6 is an operation element of the fader device 10 disposed on the back surface of the panel surface 100. By operating the operation element 6 in the vertical direction, parameter values (signals) corresponding to functions set in the channel are obtained. Value). The fader device 10 is a motor drive fader, and the operating element 6 moves up and down by driving a motor 2 described later. For the sake of convenience, the movement direction of the operation element 6 is defined as “D direction” for the downward direction and “U direction” for the upward direction. For example, the digital mixer can be connected to a computer or the like (not shown), and can receive sequence data from these external devices and automix input signals. In such a case, the operation element 6 of each channel moves in real time so that the parameter value corresponds to each scene of the sequence. The operation element 6 also moves when the power is turned on or when initial setting is performed by switching the setting of the function assigned to the channel. This function is a function for resetting parameter values in order to reproduce a scene when the power is turned off, and is called a “scene recall function”. The same applies to a fader device for stereo master (not shown).

  The panel surface 100 includes an A switch 87, a B switch 88, and a C switch 89 as switches for turning off and on the main power supply of the digital mixer. Although details will be described later, the A switch 87 is a mechanical switch corresponding to the “off mode A” for performing initialization processing of the operator position when the main power source is turned on. The B switch 88 is a soft switch corresponding to an “off mode B” for correcting the position of the operation element 6 when the main power supply is turned on. Further, the C switch 89 is a soft switch corresponding to an “off mode C” in which the parameter value can be changed by operating the operator 6 while the main power is off. In the later-described processing of this embodiment, when the main power is turned off with the B switch 88 or the C switch 89, the power off state is the same, but when the main power on is designated thereafter, the B switch 88 or By selecting the C switch 89, the main power-on process by the “off mode B” and the main power-on process by the “off mode C” are selected.

  As shown in FIG. 1, the digital mixer of the embodiment includes a CPU 20, a flash memory 30, a RAM 40, an operation unit 50, a signal processing unit 60, a display 70, a PC input / output circuit (I / O) 80, and the fader device 10. , 10,..., 10,..., A main power supply 91 for supplying power to each part of the digital mixer, and a battery 92 as a backup power supply when the power supply by the main power supply 91 is turned off.

  The signal processing unit 60 is configured by a DSP, and a plurality of analog / digital conversion boxes or digital interface boxes (AD / DIO) can be connected to the signal processing unit 60 via input connectors. . Each analog / digital conversion box can have up to eight A / D conversion boards, and the gain and polarity can be set for each analog / digital conversion input. Each digital interface box can have up to eight I / O boards. In addition, a plurality of digital / analog conversion boxes / digital interface boxes (DA / DIO) can be connected to the signal processing unit 60 via output connectors. Each digital / analog conversion box can have up to eight D / A conversion boards, and gain and polarity can be set for each digital / analog conversion output. The signal processing unit 60 performs mixer processing according to various functions set by the CPU 20.

  Further, when the main power supply 91 is turned off due to “off mode B” or “off mode C” described later, the CPU 20 uses the backup power supply of the battery 92 for the pulse signal from the fader device 10 during the power off. The operation to monitor is performed. Even when the main power supply 91 is turned off by an “off mode A” described later, the backup of the time and memory is performed by the backup power supply of the battery 92.

  The operation program executed by the CPU 20 is stored in the flash memory 30. The CPU 20 detects the operation of each of the fader devices 10, 10,... Of the fader group 10A and the operation of the operation unit 50, and the mixer of the signal processing unit 60 Control of processing and display of the display 70 are controlled. Further, the CPU 20 controls the driving of a motor 2 described later of the fader device 10 and controls the position of the operation element 6 in the fader device 10 as described above.

  Next, details of the fader device 10 will be described with reference to FIG. The fader device 10 of this embodiment includes a side plate 1a that forms a right-angled surface behind the panel surface 100, a side plate (not shown) that is paired with the side plate 1a on the front side, A frame is constituted by the frame 1b. The motor 2 is attached to one end of the upper frame 1b, and the entire frame is attached to the back surface of the front panel 100 by fasteners 11A and 11B on both sides of the upper frame 1b. Further, claws 12a, 12a, 12b, 12b are erected by bending at both ends of the side plate 1a, and a moving guide body 3 constituting a "linear scale" is formed between the claws 12a, 12a between the claws 12b, 12b. The auxiliary movement guide body 4 is attached to the. A movement block 5 is attached to the movement guide body 3 and the sub movement guide body 4 so as to be slidable in the longitudinal direction of the movement guide body 3 and the sub movement guide body 4. In addition, a lever 6 a constituting a part of the operation element 6 is attached to the moving block 5.

  With the above configuration, when the operation element 6 is manually reciprocated, the moving block 5 moves along the moving guide body 3 and the sub moving guide body 4. And if the moving block 5 moves to the motor 2 side (D direction) and the lever 6a of the operation element 6 contacts the stopper 11A, the further movement becomes impossible. Further, when the moving block 5 moves to the side opposite to the motor 2 (U direction) and the lever 6a of the operation element 6 contacts the stopper 11B, no further movement is possible. That is, the stoppers 11A and 11B are stopper portions that limit the movement range of the operation element 6 that can be manually operated.

  Although not shown in the drawing, a pulley is attached to each of the drive shaft of the motor 2 and the other end of the upper frame 1b around which a timing belt is wound, and an upper portion of the moving block 5 is attached to the timing belt. It has been. Accordingly, the moving block 5 reciprocates along the moving guide body 3 and the sub moving guide body 4 by forward and reverse rotation of the motor 2, and the position of the operation element 6 is controlled by the CPU 20 as described above. Even when the operating element 6 is moved by driving the motor 2, the rotation of the motor 2 is stopped at the position where the lever 6a is in contact with the stopper 11A or the stopper 11B (the state where the load is detected). Become.

  The moving block 5 is resin-molded, and guide holes 5a and 5a into which the moving guide body 3 is inserted into the upper side of the square-shaped frame, and a sub guide into which the sub moving guide body 4 is inserted into the lower side. Holes 5b and 5b are respectively formed. A substrate 5c is attached to the inside of the frame, and a magnetic sensor 7 as a sensor unit is attached to the substrate 5c. A flat cable 7a for outputting a signal from the magnetic sensor 7 is connected to the substrate 5c.

  The moving guide body 3 includes a shaft portion 31 made of nonmagnetic stainless steel and a scale portion 32 formed by scale magnetizing a permanent magnet material. The scale portion 32 has a magnetic pole formed by alternately polarizing the N pole and the S pole in the longitudinal direction of the scale portion 32 as a marking, for example, with a period (pitch) of 330 μm. The magnetic sensor 7 is disposed opposite to the magnetic sensor 7. The magnetic sensor 7 includes two magnetoresistive elements (MR elements). When the moving block 5 moves along the moving guide body 3 and the sub moving guide body 4 which are linear scales, the magnetic sensor 7 is a scale unit. Detects 32 magnetic poles and outputs a pulse signal. The pulse signal of the magnetic sensor 7 is sent to the CPU 20 and the like via the flat cable 7a.

  That is, as the moving block 5 moves, the magnetic sensor 7 outputs a pulse signal corresponding to the reversal of the polarity of the N pole and S pole of the scale unit 32. The fluctuation amount or movement amount (length) of the moving block 5 (operation element 6) can be detected from the number of pulse signals. Further, the magnetic poles of the scale portion 32 are composed of, for example, two rows, and the phase of this magnetic pole pattern is shifted by 1 / 2π in the longitudinal direction of the scale portion 32, and the magnetic sensor 7 outputs a pulse signal having a phase shift. Therefore, the moving direction of the moving block 5 is determined based on the opposite direction of the phase shift. The magnetic pole pattern of the scale portion 32 is composed of an NSNS... Pattern having no phase shift, and the detection pole portion of the sensor may be arranged with a shift of 1 / 2π.

  In this embodiment, there are three modes of “off mode A”, “off mode B”, and “off mode C” as main power off and main power on modes. In the “off mode A”, all functions are stopped by turning off the main power, and regardless of whether or not the operation element 6 is operated by the fader apparatus 10 during the main power off, Perform initialization processing.

  In the “off mode B”, power supply from the main power supply 91 is stopped by turning off the main power supply, and main functions such as mixing processing are stopped. However, when power is supplied from the battery 92, the CPU 20 performs processing such as monitoring whether the operation element 6 is operated or counting of pulse signals. When the main power is on, if the operation element 6 is operated by the fader device 10 while the main power is off, the operation element 6 is moved by the operation amount in the opposite direction to the operation. That is, the operation amount (variation amount) is corrected (offset). The parameter value corresponding to the corrected operation element 6 is a value (stored value) immediately before the power is turned off. Thereby, even when the operation element 6 is moved carelessly while the main power is off, the state immediately before the power is turned off can be restored.

  In the “off mode C”, main functions such as mixing processing are stopped when the main power is turned off as in the “off mode B”, and the CPU 20 uses the power source from the battery 92 to monitor the presence / absence of operation and count pulse signals. The process is performed. On the other hand, in the “off mode C”, when the main power is on, if the operation element 6 is operated by the fader device 10 while the main power is off, the operation amount (variation amount) of the operation element 6 is corrected. Without performing this, the parameter value (stored value) immediately before the power-off corresponding to the operation element 6 is changed (corrected) by a value corresponding to the operation amount and set. As a result, the user can change and set the parameter value by operating the operator 6 while the power is off.

  The function of turning off the main power supply in “off mode B” or “off mode C” corresponds to the “power off function” in the claims, and the function of turning on the main power supply in “off mode B”. The function corresponding to the “start-up function” and turning on the main power in the “off mode C” corresponds to the “start-up sub-function” in the claims.

  4 is a flowchart of a main process executed by the CPU 20, FIG. 5 is a flowchart of an interrupt process executed in parallel with the main process, and FIG. 6 is a flowchart of a fader initialization process (an operator position initialization process). A specific operation will be described based on the flowchart. For ease of understanding, the fader initialization process in FIG. 6, the interrupt process in FIG. 5, and the main process in FIG. 4 will be described in this order.

  The fader initialization process of FIG. 6 is started when the main switch on is instructed by the A switch 87 or when the function assigned to the fader device 10 is switched. First, the motor 2 of the corresponding fader device 10 is driven in the D direction in step S41, and the operation element 6 is moved to the initial position until the stop of the rotation of the motor 2 is detected in step S42. When it is detected that an abnormal load is applied to the motor 2, the operating element 6 comes into contact with the stopper portion (stopping metal 11A) and the motor 2 is stopped. When the motor 2 stops, the process proceeds to step S43, and the count value of the pulse signal in the fader device 10 is reset to “0”.

  Next, in step S44, the motor 2 is reversed and driven in the U direction. In step S45, the motor 2 is monitored to stop in step S46 while incrementing the reset count value in accordance with a separately detected pulse signal. . When the motor 2 stops, the scale status is calculated in step S47. That is, since the count value of the entire scale has been acquired in steps S43 to S46, if the function parameters assigned to this fader device 10 are, for example, in 64 stages, the total count value is set to “64”. The count value per step of the parameter is obtained by dividing by.

  Next, in step S48, the position (number of pulses) corresponding to the initial value of the function currently assigned to the fader device 10 is calculated. In step S49, the motor 2 is driven in the D direction, and is detected separately in step S50. While the count value is decremented according to the pulse, it is monitored that the count value reaches the position of the pulse calculated in step S51. When the pulse position is reached, the driving of the motor 2 is stopped in step S52, and the process returns to the original routine. As a result, the function assigned to the fader device 10 can be initialized.

  The “interrupt processing” in FIG. 5 is started when the main power is turned on by the A switch 87 (main power is on). If the main power off is instructed by operating the A switch 87, that is, if all functions are stopped in step S16 of the main process described later, this "interrupt processing" is stopped, but "off mode B" Or, when the power is turned off in the “off mode C”, this “interrupt processing” is continued.

  First, the operation state of each of the A switch 87, the B switch 88, and the C switch 89 is determined in steps S21 to S23, and if there is an operation, it corresponds to the switch that has been operated, and in steps S24 to S26. “Off mode A”, “off mode B”, and “off mode C” are notified to the main process (FIG. 4), respectively. In step S27, it is determined whether there is a pulse signal from the fader device 10, and if there is a pulse signal, the processing from step S30 is performed. If there is no pulse signal, it is determined in step S28 whether the mode is "off mode B" or "off mode C". If it is either “off mode B” or “off mode C”, the power is off, and the process returns to the original routine. Otherwise, in step S29, the other switches are scanned and the scan result is obtained. Corresponding processing is performed accordingly, and the process returns to the original routine.

  If there is a pulse signal from the fader device 10 in step S27, the current count value corresponding to the fader device 10 corresponding to the pulse signal is increased or decreased in step S30. Then, “off mode B”, “off mode C”, or other processing is performed. In the case of “OFF mode B” in step S31, the fader initialization flag is turned on in step S32 so that the position of the operator 6 is corrected in the main process, and the process returns to the original routine. If “OFF mode C” in step S33, the value increased or decreased in the signal processing flow in step S34 is recorded, and the process returns to the original routine. Thereby, the parameter setting value of the fader device operated in the main power off state is reflected in the signal processing. If it is neither “off mode B” nor “off mode C”, the signal processing flow in step S35 is notified of the increased / decreased value, and the process returns to the original routine. As a result, the operation of the fader device 10 in the normal operation state in which the main power is on is reflected in the signal processing.

  The “main process” in FIG. 4 is started when the main power is turned on by the A switch 87 (main power on). First, in step S1, other initialization processes such as flag and register reset are performed. In step S2, the fader initialization process (initialization process of the operator position) in FIG. 5 is performed, and the process proceeds to step S3.

  In step S <b> 3, device setting processing (panel setting processing) is performed in accordance with the operation of various controls arranged on panel 100. That is, various controls are scanned in the interrupt process shown in FIG. 6 described later, and the result of the scan is acquired by the panel setting process in step S3. Then, in step S4, various function setting processing in a normal operation state of power-on such as various signal processing relating to mixing or the like is performed according to the acquired contents. In addition, the result of the cancellation of the A switch 87, the B switch 88, and the C switch 89 acquired in step S3 is reflected in the subsequent power-off and power-on processing.

  That is, in step S5, it is determined whether or not “off mode A” is selected, and in step S6, whether or not “off mode B” or “off mode C” is selected is determined. If “OFF mode A” is selected (ie, operation of the A switch 87), the current state is the power-on state, so the device setting state is stored in step S15 and all functions are stopped in step S16. The process is terminated. If “OFF mode B” or “OFF mode C” is not selected in step S6, that is, if there is no operation of either the B switch 88 or the C switch 89, the process returns to step S3 to process the normal operation state. repeat. If “off mode B” or “off mode C” is selected, the processes in and after step S7 are performed.

  In step S7, the main function is stopped. However, this flow executed by the CPU 20 and the interrupt process of FIG. 5 continue. Next, in steps S8 to S10, it is determined whether or not “off mode A”, “off mode B”, and “off mode C” are selected, and if none is selected, the process returns to step S7. That is, the process of repeating Step S7 to Step S10 is the main power supply off state, that is, the standby state in the “off mode B” or “off mode C”, and the corresponding process is performed if each mode is selected.

  When “OFF mode A” is selected in step S8, device setting information corresponding to the operation in the standby state is generated in step S14, the device setting state is stored in step S15, and all functions are performed in step S16. Stop and end processing. This flow is a process of shifting from the standby state in “off mode B” or “off mode C” to “off mode A” to turn off the main power.

  If “off mode B” is selected in step S9, it is an operation of the B switch 88 in the main power off state in “off mode B” (or “off mode C”), and corresponds to “off mode B”. To turn on the main power. Accordingly, in step S12, it is determined whether or not the “initialization flag is on”. If “the initialization flag is not on”, the process returns to step S3 to return to the normal operation state. That is, the initialization process of the operator position is prohibited and the main power supply is turned on. If the “initialization flag is ON”, the position of the operation element 6 that has been operated while the power is off is corrected by the operation amount (variation amount) in step S13, and the process returns to step S3 to return to normal. Return to the operating state. That is, only the position of the operating element 6 is moved by the fluctuation amount, and the time is shortened compared with the normal initialization process of the operating element position, and the load caused by driving the motor 2 is also reduced.

  If “OFF mode C” is selected in step S10, in this case, the main power ON corresponding to “OFF mode C” is instructed by the C switch 89. In step S11, the operation is performed while the power is OFF. The parameter value corresponding to the operation element 6 having the above is changed (corrected) by the value corresponding to the operation amount (variation amount), and the process returns to step S3 to return to the normal operation state. If there is no operation while the power is off, the process returns to step S3 as it is, so that the initialization process of the operator position is prohibited and the main power is turned on.

  In the embodiment, the B switch 88 and the C switch 89 are separate switches. However, for example, when one “B / C switch” is provided and “off mode B” is designated, a short pressing operation, that is, “short pressing” is performed. When “off mode C” is designated, a long (about 1 second) pressing operation, that is, “long pressing” may be performed.

  Further, in the embodiment, an example of a magnetic type has been described, but an optical type may be used. In this case, for example, in the example of FIG. 3, for example, black and white barcode-shaped patterns with a fixed period are formed on the lower surface of the moving guide body 3, and instead of the magnetic sensor 7, a light emitting diode and a photodiode are used. A configured photo sensor is provided, and a pulse signal having the phase difference corresponding to two rows by the black and white pattern is obtained as a detection signal. Further, a variable resistance type may be used in which a slider on the operating element side is brought into contact with a linear scale composed of a resistor, and the position of the operating element is detected by a resistance value via the slider and the linear scale. .
