Multiple output reel module

Abstract
A multiple output reel module includes a reel wheel supporting a plurality of spindles. Mounted to each spindle is a reel. The reel wheel is rotatable to position one of the spindle and reel combinations in a loading position in which output media from a nearby machine is interconnected to the reel. The spindle and reel are rotated to load the reel with output media. A CPU monitors the status of the reel, and stops the loading when the reel is full. The CPU then rotates the reel wheel to position a second spindle and reel combination in the loading position. The output media is automatically positioned over a portion of the second reel, and the output media is automatically interconnected to the second reel with an over-center finger assembly. Then the output media between the two reels is cut and the second reel is loaded with output media.
Description




BACKGROUND




The invention relates to an output reel module for use with taper apparatus for packaging computer chips.




SUMMARY




The present invention provides a multiple output reel module for use with a device that produces a flexible output media. The module includes a base, first and second spindles supported by the base, a reel mounted onto each of the first and second spindles for rotation therewith, and a mechanism for moving the first and second spindles into and out of a loading position. The module also includes an attachment mechanism attaching the output media to the spindles that is in the loading position. The module also includes a reel motor selectively rotating the spindles that is in the loading position, such that the output media is loaded onto the reel in the loading position.




Once the reel on the first spindle is loaded, the module automatically actuates the mechanism for moving the spindles, and moves the first spindle out of the loading position and the second spindle into the loading position. The attachment mechanism automatically attaches the output media to the reel on the second spindle when the second spindle is in the loading position, and the reel motor automatically loads the reel on the second spindle with output media after the output media is attached to the reel.




The module may also include a cutting mechanism for cutting the output media between the reels on the first and second spindles prior to loading the reel on the second spindle with output media. The module permits the automatic loading of a second reel of output media while an operator sees to replacing the full reel on the first spindle with an empty reel.




Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims, and drawings.

DETAILED DESCRIPTION





FIG. 1

illustrates a taper machine


10


that includes a reel


14


of carrier tape


16


, an inspection device


18


, and a reel


22


of cover tape


24


(FIG.


15


). The carrier tape


16


includes recessed pockets or compartments


26


(FIG.


15


). The taper machine


10


inspects electronic components or parts


30


(

FIG. 15

) with the inspection device


18


, and then deposits the parts


30


into the compartments


26


of the carrier tape


16


. The taper machine


10


also affixes the cover tape


24


to the carrier tape


16


such that the compartments


26


are sealed by the cover tape


24


, with the parts


30


trapped in the compartments


26


. The taper machine


10


includes a central processing unit (“CPU”)


34


that controls the operation of the taper machine


10


. It should be noted that, although a taper machine


10


is illustrated, the invention may be used with virtually any machine that outputs a flexible media (e.g., tape, film, rope, cable, etc.) that is to be wound onto reels or spools.





FIGS. 1-3

illustrate a multiple output reel module (“MROM”)


38


embodying the invention. Wires


42


interconnect the MROM


38


to the CPU


34


on the taper machine


10


in the illustrated construction to coordinate operation of the MROM


38


and taper machine


10


. In alternative constructions, a separate CPU may be mounted on-board the MROM


38


, and may communicate with the CPU


34


aboard the taper machine


10


. Additionally, the MROM


38


may be used with other types of taper machines


10


than the one illustrated, and may receive the flexible media from either the right side (as illustrated) or from the left side. In the event the flexible media is fed to the MROM


38


from the left side, the arrangement of parts would be a substantial mirror image of that shown. The MROM


38


includes a system base or pillar


46


, a reel wheel or trunnion


50


rotatably mounted to the base


46


, and a wheel drive assembly


54


mounted to the base


46


.




With reference to

FIGS. 4 and 5

, the wheel


50


includes an axle


58


that is supported for rotation by two bearings


62


in the base


46


. The wheel


50


supports first, second, and third spindle assemblies


71


,


72


,


73


. The spindle assemblies


71


,


72


,


73


are spaced around the wheel


50


in 120° increments. It should be noted that although the illustrated embodiment includes three spindle assemblies, the wheel


50


may carry as few as two or more than three spindle assemblies. Each spindle assembly


71


,


72


,


73


supports a reel


74


as will be discussed in more detail below. In

FIG. 4

, the first spindle


71


assembly is in a loading position, the second spindle assembly


72


is in an on-deck position, and the third spindle assembly


73


is in a change-out position. The spindle assembly in the loading position is spaced from the output of the taper machine


10


a pocket offset distance


78


. The CPU


34


is programmed with the pocket offset distance


78


(FIG.


1


), the significance of which will be discussed below.




As seen in

FIGS. 3-7

, the wheel drive assembly


54


includes a wheel motor


82


mounted to the base


46


and having an output shaft


86


. A worm gear


90


is coupled to the output shaft


86


and is rotatable therewith in response to operation of the wheel motor


82


. A worm gear support block


94


supports the worm gear


90


at each end. A gear/sensor plate assembly


100


is mounted to the wheel's axle


58


, and meshes with the worm gear


90


such that operation of the wheel motor


82


causes rotation of the wheel


50


through the worm gear


90


and gear/sensor plate assembly


100


.




The wheel motor


82


is operable in forward and backward directions to cause counterclockwise and clockwise rotation (as seen in FIG.


1


), respectively, of the wheel


50


. A forked interrupt sensor


104


is mounted to the base


46


, and three detector pins


108


are mounted to the gear/sensor plate assembly


100


at 120° increments. When one of the detector pins


108


is positioned between the arms of the forked sensor


104


, a corresponding one of the spindle assemblies


71


,


72


,


73


is positioned in the loading position. Both the wheel motor


82


and the interrupt sensor


104


are wired to the CPU


34


so that the CPU


34


is informed of the presence of a detector pin


108


within the interrupt sensor


104


.




Referring to

FIG. 8

, the first spindle assembly


71


will be described, it being understood that the second and third spindle assemblies


72


,


73


are substantially identical to the first spindle assembly


71


. The spindle assembly


71


includes a bearing assembly


112


, a spindle


116


, and a key


120


. The bearing assembly


112


includes a housing


124


mounted to the wheel


50


and supporting two bearings


128


. The spindle


116


extends through the bearing assembly


112


and is supported by the bearings


128


in cantilever fashion for rotation with respect to the wheel


50


. The spindle


116


includes an outer end and an inner end on opposite sides of the wheel


50


. The key


120


is supported by the outer end of the spindle


116


and is biased by springs to an extended position (illustrated in FIG.


8


). The key


120


rotationally couples a reel


74


to the spindle


116


(as will be further discussed below), while still allowing for the quick change-out of one reel


74


for another on the spindle


116


.




Referring now to

FIG. 9

, the inner end of the spindle


116


extends through a hole in the wheel


50


, and is coupled to a detent assembly


132


. The detent assembly


132


includes three or more bolts


136


threaded into the wheel


50


and having bolt heads


140


, a compression spring


144


surrounding each bolt


136


, and a brake plate


148


captured between the bolt heads


140


and the springs


144


such that the springs


144


bias the brake plate


148


against the bolt heads


140


. The brake plate


148


includes three detents or depressions


152


spaced 120° from each other. The detent assembly


132


also includes a brake hub


156


that is affixed to the inner end of the spindle


116


with a set screw


160


or other suitable fastener so that the brake hub


156


and spindle


116


rotate together. The brake hub


156


extends through the brake plate


148


and has a flange extending generally parallel to the brake plate


148


. Three ball bearings


164


are housed in the flange of the brake hub


156


at 120° increments and are sandwiched between the brake hub


156


flange and the brake plate


148


. The ball bearings


164


are aligned with the detents


152


such that the detent assembly


132


resists rotation of the spindle


116


when the ball bearings


164


are captured in the detents


152


.




Referring to

FIG. 10

, the MROM


38


has a reel drive assembly


168


that includes a reel motor actuator


172


(e.g., a pneumatic actuator or other suitable actuator) mounted to the base


46


. The reel motor actuator


172


includes a piston rod that is linearly actuable. The reel drive assembly


168


also includes a drive hub assembly


176


, a reel motor


180


, and a flexible coupling


184


. The drive hub assembly


176


includes a substantially vertical plate


188


, a radial bearing assembly


192


, a drive shaft


196


, a drive hub


200


, a rubber ring pad


204


, a bullet nose dowel


208


constructed of hardened steel, and three deflector pins


212


. The radial bearing assembly


192


is mounted to the vertical plate


188


and supports the drive shaft


196


for rotation. The drive hub


200


is rotationally fixed to the drive shaft


196


with a set screw or other suitable fastener. The rubber ring pad


204


is mounted to the face of the drive hub


200


and encircles the bullet nose dowel


208


. The deflector pins


212


extend from the vertical plate


188


alongside the drive hub


200


.




An L-shaped bracket


216


is mounted to the vertical plate


188


. The reel motor


180


is mounted to the downwardly extending portion of the L-shaped bracket


216


. An output shaft of the reel motor


216


extends through a hole in the L-shaped bracket


216


and rotates in response to operation of the reel motor


180


. The reel motor


180


is interconnected with and controlled by the CPU


34


. The flexible coupling


184


interconnects the reel motor output shaft and the drive shaft


196


such that the drive shaft


196


and drive hub


200


rotate together in response to operation of the reel motor


180


.




The reel drive assembly


168


also includes a hardened steel bushing


220


(

FIG. 9

) inside the brake hub


156


and fixed for rotation therewith. The brake hub


156


also includes a machined face


224


surrounding the bushing


220


. The reel drive assembly


168


is positioned adjacent the loading position (i.e., at the top of the wheel


50


). As shown in phantom in

FIG. 10

, the reel motor actuator


172


is actuable under the control of the CPU


34


to move the reel motor


180


and drive hub


200


(along with the vertical plate


188


and L-bracket


216


) toward the spindle assembly


71


,


72


, or


73


in the loading position such that the bullet nose dowel


208


extends into the steel bushing


220


in the brake hub


156


. At the same time, the deflector pins


212


abut the brake plate


148


, deflecting the compression springs


144


and disengaging the brake plate


148


from the ball bearings


164


(i.e., disengaging the detent mechanism). Also, the rubber ring


204


engages the machined face


224


of the brake hub


156


, which couples the spindle assembly


71


,


72


, or


73


to the drive hub assembly


176


and permits the spindle


116


to be rotated by the reel motor


180


. The reel drive assembly


168


therefore operates as a clutch.




With reference to

FIG. 11

one of the reels


74


will now be described, it being understood that the reels


74


are substantially identical to each other. The reel


74


includes a hub portion


228


and a hole


232


extending through the hub portion


228


. The reel


74


also includes three windows


236


. Three radial slots


240


are formed in the hub portion


228


. The radial slots


240


extend along lines that substantially bisect the respective windows


236


. The reel


74


may be loaded on a spindle assembly


71


,


72


, or


73


by simply sliding the spindle


116


through the hole


232


in the hub portion


228


. The key mechanism


120


includes a nose


244


to facilitate sliding a reel


74


onto the spindle


116


. The key


120


in the spindle


116


deflects if not aligned with one of the slots


240


. The hub portion


228


may then be rotated until one of the slots


240


aligns with the key


120


, at which time the spring-biased key


120


snaps into the slot


240


. The key


120


couples the reel


74


to the spindle


116


to cause rotation of the reel


74


and spindle


116


together.





FIGS. 11-17

illustrate a finger assembly


248


. Each spindle assembly


71


,


72


,


73


carries its own finger assembly


248


, and it should be understood that the finger assemblies


248


are substantially identical to each other. The finger assembly


248


includes a proximity arm


252


, and a clamp


256


, counterweight


260


, and latching finger


264


mounted to the proximity arm


252


. The clamp


256


is affixed to the spindle


116


by turning a bolt


268


that closes the clamp


256


around the spindle


116


. The clamp


256


ensures that the finger assembly


248


rotates with the spindle


116


. A slot


272


in the clamp


256


is engaged by the key


120


, which ensures that the latching finger


264


is aligned with a window


236


of the reel


74


.




The latching finger


264


is pivotal with respect to the proximity arm


252


, and is movable between a full up position (FIG.


14


), a middle or tape engaging position (FIG.


15


), and a full down position (FIG.


16


). A spring


276


or other suitable over-center biasing member is attached to the latching finger


264


and acts along a line of force


280


. When the line of force


280


is below the pivot point


284


of the latching finger


264


(i.e., “under center”), the spring


276


biases the latching finger


264


toward the full up position (FIG.


14


). When the line of force


280


is above the pivot point


284


of the latching finger


264


(i.e., “over center”), the spring


276


biases the latching finger


264


toward the middle and full down positions (FIGS.


15


and


16


). The line of force


280


of the spring


276


crosses the pivot point


284


of the latching finger


264


(i.e., is “centered”) when the latching finger


264


is positioned between the full up and middle positions. The latching finger


264


includes a stop member


288


having top and bottom ends, and also includes a manual actuator


292


to facilitate manually cocking the latching finger


264


to the full up position. The latching finger


264


also includes a nose or finger


296


extending through the window


236


in the reel


74


when the latching finger


264


is in the middle position.




A gate


300


is mounted to the base


46


near the loading position, and is mounted to a pneumatic cylinder


304


or other suitable gate actuator that is controlled by the CPU


34


. The gate


300


is generally L-shaped and includes a trigger face portion


308


and a stopping wall


312


. The top of the latching finger stop member


288


engages the stopping wall


312


of the gate


300


when the latching finger


264


is in the full up position, and the bottom of the latching finger stop member


288


engages the stopping wall


312


when the latching finger


264


is in the full down position. However, when the latching finger


264


is in the middle position, the stop member


288


is substantially vertical and does not interfere with the stopping wall


312


.




With specific reference to

FIG. 17

, a proximity sensor


316


is mounted to the base


46


above the gate


300


near the loading position. When the stop member


288


of the latching finger


264


engages the side of the stopping wall


312


, the proximity arm


252


of the finger assembly


248


is positioned in front of the proximity sensor


316


. The proximity sensor


316


is interconnected with the CPU


34


.




As seen in

FIGS. 1 and 19

, the wheel


50


includes three cutter slots


320


evenly spaced around its perimeter. A pair of tape guide posts


324


are mounted to the wheel


50


on opposite sides of each cutter slot


320


. When one of the spindle assemblies


71


,


72


,


73


is in the loading position, one of the slots


320


is positioned in front of a tape cutting or scissors assembly


328


(FIGS.


18


and


19


). As will be described in more detail below, the tape guide posts


324


support a span of tape


16


extending across the slot


320


in front of the tape cutting assembly


328


so that the tape cutting assembly


328


can cut the tape


16


.




The tape cutting assembly


328


is best illustrated in

FIGS. 18 and 19

, and includes a double-acting magnetically-coupled pneumatic actuator


332


or another suitable actuator, which may be a pneumatic actuator or other appropriate actuator. The illustrated actuator


332


includes a cylinder


336


and a movable member


340


movable along the cylinder


336


. The scissors assembly


328


also includes first and second blades


344


,


348


that together act as a pair of scissors. The first blade


344


is mounted to a bearing block


352


that is slidable along a rod


356


. The second blade


348


is pivotally mounted to an extension plate


360


that is mounted to the movable member


340


of the scissors actuator


332


. The actuator


332


is activated by the CPU


34


to selectively move the movable member


340


along the length of the actuator cylinder


336


in forward and reverse directions


361


,


362


.




The second blade


348


is pivotally interconnected with the first blade


344


so that the two blades


344


,


348


move together out of the slot


320


as the scissors actuator


332


moves the movable member


340


forward


361


. When the bearing block


352


runs into a stop


364


, the forward motion of the first blade


344


is stopped. The movable portion


340


of the scissors actuator


332


, however, may continue its forward motion even after the first blade


344


has been stopped. Such forward motion causes the second blade


348


to pivot with respect to both the extension plate


360


and the first blade


344


in a conventional scissors cutting motion. The tape


16


spanning the slot


320


and supported by the tape guide posts


324


is thus cut by the blades


344


,


348


. A return spring


368


separates the blades


344


,


348


as the scissors actuator


332


moves the movable portion


340


in the reverse direction


362


and retracts the blades


344


,


348


through the slot


320


. Interrupt switches


372


and a tab


376


on the movable portion


340


of the scissors actuator


332


are used to inform the CPU


34


when the movable portion


340


of the scissors actuator


332


is in the fully retracted and fully extended positions.




In operation, as seen in

FIG. 22-24

, the first, second, and third spindles


71


,


72


,


73


are in the loading, on-deck, and change-out positions, respectively, and each spindle supports a reel


74


. The latching fingers


264


on each of the three spindles


71


,


72


,


73


are manually moved to the full up position by pressing on the manual actuator


292


. The output tape


16


from the taper machine


10


is positioned against the hub


228


of the reel


74


in the loading position, and the operator manually moves the latching finger


264


on the first spindle


71


to the middle position such that the nose


296


of the latching finger


264


traps the tape


16


against the hub


228


.




The operator then pushes a start button


380


(FIG.


1


), which causes the CPU


34


to begin operation of the MROM


38


and taper machine


10


. The CPU


34


first checks the proximity sensor


316


to ensure that the proximity arm


252


is positioned there. If the proximity arm


252


is detected, the CPU


34


activates the reel drive assembly


168


. The reel motor actuator


172


causes the drive hub assembly


176


to engage the brake hub


156


, and causes the deflector pins


212


to deflect the brake plate


148


and disengage the detent mechanism


132


. Once the drive hub assembly


176


and the brake hub


156


are coupled together by engagement of the rubber ring


204


and the machined face


224


, the CPU


34


activates the reel motor


180


to rotate the first spindle


71


and wind the tape


16


onto the reel


74


in the loading position.




Turning to

FIGS. 20 and 21

, a dancer


384


rests on the length of tape


16


extending between the reel


74


and the taper machine


10


. As the tape


16


becomes slack, the dancer


384


drops under its own weight. A lower limit switch


388


is activated when the dancer


384


falls below a predetermined height, which causes the CPU


34


to activate the reel motor


180


. As the tape


16


is tightened due to the reel


74


taking up more tape


16


than the taper machine


10


is putting out, the dancer


384


reaches a predetermined height (shown in phantom in

FIG. 20

) and activates an upper limit switch


392


. The CPU


34


shuts down the reel motor


180


in response to the dancer


384


activating the upper limit switch


392


.




The CPU


34


keeps track of how much tape


16


has been fed out by the taper machine


10


. The CPU


34


may be programmed to stop loading the reel


74


once a selected amount or “run” of tape


16


has been paid out. The CPU


34


factors in the pocket offset distance


78


in determining when the entire run of tape


16


has been loaded onto the reel


74


on the first spindle


71


. Thus, the CPU


34


will not move the first spindle


71


from the loading position until the taper


10


has produced an entire run plus a length of tape equal to the pocket offset distance


78


. At the end of a run, the CPU


34


also causes the taper machine


10


to pay out a length of empty pockets


26


.




Once the desired amount of tape


16


is wound onto the reel


74


in the loading position, the CPU


34


activates the reel motor actuator


172


to retract the reel motor


180


and disengage the first spindle


71


. The springs


144


of the detent mechanism


132


re-engage the detent mechanism once the reel motor


180


and deflector pins


212


are retracted. The first spindle


71


rotates under the influence of gravity until the ball bearings


164


fall into the detents


152


(i.e., the first spindle


71


rotates less than 120° because there are three detents


152


). The detent mechanism


132


then resists further rotation of the first spindle


71


and unwinding of the tape


16


from the reel


74


on the first spindle


71


.




The CPU


34


then actuates the wheel motor


82


, and causes the wheel


50


to rotate in the forward direction. Once one of the detector pins


108


passes between the arms of the forked sensor


104


, the CPU


34


incrementally steps the wheel motor


82


to cause small rotations of the output shaft


86


in the forward direction. The CPU


34


counts the number of steps required to pass the detector pin


108


entirely through the sensor


104


, and then rotates the output shaft


86


in the reverse direction half of those steps to as closely as possible position the corresponding spindle (the second spindle


72


in this instance) in the loading position.




As seen in

FIG. 23

, the second spindle


72


is now in the loading position, the first spindle


71


is in the change-out position, and the third spindle


73


is in the on-deck position. Because the reels


74


on the first and second spindles


71


,


72


are substantially co-planar, the tape


16


trailing from the reel


74


on the first spindle


71


drapes across the tape guide posts


324


and across the reel


74


on the second spindle


72


. The portion of tape


16


extending between the first and second reels


71


,


72


includes a length of empty tape compartments.




Once the CPU


34


has verified the presence of the proximity arm


252


in front of the proximity sensor


316


, the CPU


34


activates the gate actuator


304


, which moves the gate


300


toward the latching finger


264


. The trigger face


308


of the gate


300


engages the top of the stop member


288


to urge the latching finger


364


toward the middle and full down positions. The nose


296


extends through the window


236


in the reel


74


. The orientation of the window


236


in front of the finger


296


is assured by the engagement of the key


120


in the radial slots


240


of the hub


228


.




Once the latching finger


264


is “over center,” as discussed above, the spring


276


biases the latching finger


264


down against the hub


228


of the reel


74


in the loading position. The nose


296


therefore traps the tape


16


against the hub


228


of the reel


74


on the second spindle


72


. Then the CPU


34


retracts the gate


300


by activating the gate actuator


304


in the opposite direction. The latching finger


264


is left in the middle position with the stop member


288


oriented substantially vertically. In this position, the latching finger


264


clears the stopping wall


312


of the gate


300


and the second spindle


72


may be rotated.




The CPU


34


then activates the cutting assembly


328


, which extends the blades


344


,


348


out of the slot


320


in the wheel


50


. The blades


344


,


348


cut the tape


16


between the first and second spindles


71


,


72


, leaving a tail of tape


16


hanging from both of the reels


74


on the first and second spindles


71


,


72


. The tails of tape


16


each include about half of the empty compartments discussed above. The CPU


34


then retracts the cutting assembly


328


.




The CPU


34


is preprogrammed with the appropriate information (e.g., reel size and cutting position of the scissors) to determine the length of the tail of tape


16


hanging from the reel


74


on the second spindle


72


. The CPU


34


activates the reel drive assembly


168


to rotate the second spindle


72


, but does not activate the taper machine


10


. This causes tension in the tape


16


, and permits the nose


296


to slide along the tape


16


as the second spindle rotates


72


. Once the nose


296


approaches the end of the tape


16


(as seen in FIG.


24


), the CPU


34


stops the reel motor


180


and starts up the taper machine


10


. The reel


74


is now ready to begin winding tape


16


. Because the nose


296


is slid close to the end of the tape


16


, the tape


16


is prevented from bending back on itself during the first rotation of the reel


74


. The reel


74


on the second spindle


72


is loaded in a similar manner as described above for the first spindle


71


.




As the reel


74


on the second spindle


72


is being loaded, the reel


74


on the first spindle


71


may be changed out with an empty reel


74


. The full reel


74


on the first spindle


71


is merely slid off the first spindle


71


, and the nose


296


slides out of the layers of tape


16


that have been wound around it. The operator then manually cocks the latching finger


264


to the full up position by pressing on the manual actuator


292


.




Once the reel


74


is loaded, the CPU


34


rotates the second spindle


72


to the change-out position, and rotates the third spindle


73


into the loading position and the first spindle


71


into the on-deck position. The first spindle


71


should now have a new, empty reel


74


on it. The same finger engaging, cutting, and reel loading procedure just described above for the second spindle


72


is executed for the third spindle


73


. The reel


74


on the second spindle


72


may be changed out for an empty one as described above for the first spindle


71


.




It should be appreciated that the taper


10


and MROM


38


may be run virtually continuously, because an operator is afforded much time to change out the empty reels


74


in the change-out position. In this regard, an operator may work at several different tape machines


10


and MROM's


38


at once. Also, it will be appreciated that the MROM


38


described above may be modified to include only two spindles or more than three spindles depending on the application.




The CPU


34


is programmed with the appropriate logic to step through the operation of the MROM


38


. The CPU


34


is also used to identify potential user errors. For example, if no reel


74


is present on the spindle assembly in the loading position, the latching finger


264


will rotate to its full down position (FIG.


16


), and the bottom of the stop member


288


will engage the stopping wall


312


of the gate


300


. The CPU


34


will sound an alarm if it there is resistance to rotation of the reel


74


in the loading position under these circumstances.




Additional interrupt sensors


396


(seen in

FIG. 1

) are also used to inform the CPU


34


of the status of the spindle assembly in the on-deck position. One of the sensors


396


identifies whether a reel


74


is present or not on the spindle assembly by detecting the presence or absence of the reel's hub


228


. The other sensor


396


is directed below the hub


228


of the reel


74


, and detects the presence of output media on the reel


74


. If there is no reel


74


in the on-deck position, or if the reel


74


is full of output media, the CPU


34


will not permit the wheel


50


to rotate the spindle assembly into the loading position. Also, the CPU


34


may sound an alarm to notify the operator of the error.
