An electronic component mounting device 10 is shown in FIG. The electronic component mounting apparatus 10 includes a mounting machine main body 20, a conveying device 22, a mounting head moving device (hereinafter abbreviated as "moving device") 24, a mounting head 26, a feeding device 28, and a control device 30 (see FIG. 3). ing. The mounting machine main body 20 is composed of a frame 32 and a beam 34 mounted on the frame 32 .

The transport device 22 includes two

conveyor devices

40 and 42. The two

conveyor devices

40 and 42 are arranged on the frame 32 so as to extend parallel to each other and in a predetermined direction. The direction in which the

conveyor devices

40 and 42 extend is called the X-axis direction, and the horizontal direction perpendicular to that direction is called the Y-axis direction. Each of the two

conveyor devices

40 and 42 conveys the circuit board supported on each

conveyor device

40 and 42 by an electromagnetic motor (see FIG. 3) 46 in the X-axis direction. Also, the circuit board is held at a predetermined position by a board holding device (see FIG. 3) 48 .

The moving device 24 is an XY robot type moving device. The moving device 24 includes an electromagnetic motor (see FIG. 3) 52 for sliding the slider 50 in the X-axis direction and an electromagnetic motor (see FIG. 3) 54 for sliding in the Y-axis direction. A mounting head 26 is attached to the slider 50 , and the mounting head 26 is moved to an arbitrary position on the frame 32 by the operation of two

electromagnetic motors

52 and 54 .

The mounting head 26 mounts electronic components on the circuit board. The mounting head 26 has a suction nozzle 60 provided on the lower end surface. The suction nozzle 60 communicates with a positive/negative pressure supply device (see FIG. 3) 62 via negative pressure air and positive pressure air passages. The suction nozzle 60 sucks and holds an electronic component with negative pressure, and releases the held electronic component with positive pressure. The mounting head 26 also has a nozzle lifting device (see FIG. 3) 64 for lifting and lowering the suction nozzle 60 . The mounting head 26 changes the vertical position of the electronic component held by the nozzle lifting device 64 .

The feeding device 28 is arranged at the front end of the frame 32 and has a plurality of tape feeders 70 . Each tape feeder 70 has a reel 72, a delivery device 74 and a stripping device 76, as shown in FIG. 2, and feeds electronic components at the end of the top surface. Specifically, the taped component 78 is wound around the reel 72 , and the reel 72 around which the taped component 78 is wound is housed in the reel housing portion 79 . A taped component 78 is pulled out onto a tape guide 80 from a reel 72 housed in a reel housing portion 79 . The taped component 78 is an electronic component taped, and feed holes (not shown) are formed at a predetermined pitch. A sprocket 82 of the delivery device 74 is meshed with the feed hole. The sprocket 82 is rotated by an electromagnetic motor 84 . With such a structure, the taped component 78 is delivered toward the supply position. Note that the electromagnetic motor 84 is provided with an encoder (see FIG. 3) 85 . The encoder 85 detects the drive position, ie, the rotation angle, of the electromagnetic motor 84 that is the drive source of the delivery device 74 , and the operation of the electromagnetic motor 84 is controlled based on the detected value of the encoder 85 . Incidentally, the encoder 85 is an absolute encoder and detects the absolute rotation angle of the electromagnetic motor. That is, the origin is set in the encoder 85, and the rotation angle from the origin is detected. Therefore, unless the electromagnetic motor 84 rotates, the rotation angle detected by the encoder 85 does not change even after the power supply to the electromagnetic motor is cut off.

The peeling device 76 also has a film peeling mechanism 86 and a gear mechanism 88 . The film peeling mechanism 86 is a mechanism for peeling the top film 90 from the taped component 78 and is arranged in front of an opening 92 formed at the top end of the tape feeder 70 . The gear mechanism 88 is a mechanism that pulls the top film 90 separated from the taped component 78 into the film collection section 94 . With such a structure, the top film 90 is peeled off from the taped component 78 , so that the electronic component housed in the taped component 78 is exposed at the opening 92 , and the exposed electronic component is attached to the mounting head 26 . is sucked and held by the sucking nozzle 60 of . That is, the opening 92 is the electronic component supply position of the tape feeder 70 . A tape guide passage 96 is formed downward on the side surface of the opening 92 in the delivery direction of the taped component 78 . Through this tape guide passage 96, the waste tape 98 from which the electronic components have been removed from the taped components 78 is discharged.

A connector 100 is provided on the side surface of the tape feeder 70 in the delivery direction of the taped components 78 . On the other hand, as shown in FIG. 1, a tape feeder mount 110 is arranged at the front end of the frame 32 . The tape feeder mounting base 110 is composed of a standing surface 112 standing vertically with respect to the frame 32 and a protruding surface 114 protruding from the lower end of the standing surface 112 . A plurality of slide grooves 116 are formed on the projecting surface 114 so as to extend in the Y direction, and connector connecting portions 118 are provided on the standing surface 112 corresponding to each of the plurality of slide grooves 116 . Then, the connector 100 of the tape feeder 70 is connected to the connector connecting portion 118 by fitting the lower end of the tape feeder 70 into the slide groove 116 . Thereby, the tape feeder 70 is mounted on the tape feeder mounting base 110 in a positioned state and electrically connected.

Also, the control device 30 includes a controller 130, a plurality of drive circuits 132, a control circuit 133, and a memory 134, as shown in FIG. A plurality of drive circuits 132 are connected to the

electromagnetic motors

46 , 52 , 54 , 84 , the substrate holding device 48 and the positive/negative pressure supply device 62 . The controller 130 includes a CPU, ROM, RAM, etc., is mainly a computer, and is connected to a plurality of drive circuits 132 . Accordingly, the controller 130 controls the operations of the conveying device 22, the moving device 24, and the like. The controller 130 is connected to the encoder 85 of the tape feeder 70 and controls the operation of the electromagnetic motor 84 of the tape feeder 70 , that is, the feeding device 74 based on the detected value of the encoder 85 . The controller 130 is also connected to the display device 136 via the control circuit 133 . Thereby, controller 130 displays an arbitrary image on display device 136 . In addition, controller 130 is also connected to memory 134 . Thereby, the controller 130 stores various information in the memory 134 and acquires various information from the memory 134 .

In the electronic component mounting apparatus 10, the mounting operation is performed by the mounting head 26 on the circuit board held by the conveying apparatus 22 with the above-described configuration. Specifically, the circuit board is transported to the work position by a command from the controller 130, and is fixedly held by the board holding device 48 at that position. Also, the tape feeder 70 feeds taped components and supplies electronic components at the supply position according to a command from the controller 130 . Then, the mounting head 26 moves above the supply position of the electronic component according to a command from the controller 130 , and the suction nozzle 60 sucks and holds the electronic component. Then, the mounting head 26 moves above the circuit board and mounts the electronic component on the circuit board.

Thus, in the electronic component mounting apparatus 10, electronic components supplied by the tape feeder 70 are mounted on the circuit board. Therefore, it is necessary to appropriately manage the types of electronic components supplied by the tape feeder 70 and identification information for identifying the tape feeder 70 . In other words, it is necessary to appropriately manage the types of electronic components of the taped components wound around the reel 72 housed in the tape feeder 70 and the identification information of the tape feeder. Therefore, when the reel 72 is accommodated in the tape feeder 70, the registration information of the electronic component is registered.

Specifically, the electronic component registration information is registered when taped components are attached to the tape feeder 70 using the loading device 150 shown in FIG. The loading device 150 is composed of a kitting stand 152 and a control device 154 . The kitting stand 152 has a mounting table 160 , a stand 162 and an upper rail 164 . The mounting table 160 supports the bottom surface of the tape feeder, and the bottom surface of the tape feeder is mounted on the top surface of the mounting table 160 . A stand 162 is erected on the upper surface of the mounting table 160 to support the side surface of the tape feeder mounted on the mounting table 160 . An upper rail 164 is provided on the upper end of the stand 162 , and the upper end surface of the tape feeder placed on the mounting table 160 is fitted to the upper rail 164 . The tape feeder is set on the kitting stand 152 in such a posture. A bracket 166 is fixed to the front side edge of the stand 162 so as to cover the front side wall of the tape feeder set on the kitting stand 152, and a connector connecting portion 168 is provided on the bracket 166. It is Therefore, when the tape feeder is set on the kitting stand 152 , the connector 100 of the tape feeder is connected to the connector connecting portion 168 . As a result, the tape feeder 70 is positioned and set on the kitting stand 152 and electrically connected.

Also, the control device 154 is connected to the connector connection portion 168 of the kitting stand 152 and controls the operation of the tape feeder set on the kitting stand 152 . Control device 154 includes controller 170 and drive circuit 172 . The controller 170 includes a CPU, ROM, RAM, etc., is mainly a computer, and is connected to a drive circuit 172 . The drive circuit 172 is connected to the electromagnetic motor 84 of the tape feeder when the tape feeder is set on the kitting stand 152 . Also, when a tape feeder is set on the kitting stand 152, the controller 170 is connected to the encoder 85 of the tape feeder. Thereby, the controller 170 controls the operation of the electromagnetic motor 84 of the tape feeder 70 , that is, the feeding device 74 based on the detection value of the encoder 85 . A code reader 176 is also connected to the controller 170 . The control device 154 is connected to the control device 30 of the electronic component mounting apparatus 10 , and various information is transmitted and received between the control device 154 and the control device 30 .

In the loading device 150 having such a structure, when taped components are attached to the tape feeder 70, electronic component registration information is registered. Specifically, a bar code is attached to the reel 72 around which the taped component is wound. Component information indicating the type of electronic component contained in the taped component wound around the reel 72 is coded in the bar code. Then, the operator reads the bar code of the reel 72 to be stored in the tape feeder using the code reader 176 . Thereby, the controller 170 acquires the part information of the taped part wound around the reel 72 .

Also, when the worker reads the barcode of the reel 72 with the code reader 176 , the reel 72 is stored in the reel storage portion 79 of the tape feeder and the tape feeder is set on the kitting stand 152 . Thereby, the tape feeder is electrically connected to the control device 154 . At this time, the controller 170 acquires tape feeder identification information from the tape feeder. The controller 170 then transmits the component information read by the code reader 176 and the tape feeder identification information acquired from the tape feeder to the control device 30 of the electronic component mounting apparatus 10 . As a result, when receiving the component information and the identification information of the tape feeder, the control device 30 associates the received component information with the identification information of the tape feeder and stores them in the memory 134 as electronic component registration information.

Also, when the tape feeder is set on the kitting stand 152 , the worker pulls out the tip of the taped component from the reel 72 stored in the tape feeder and feeds it along the upper surface of the tape guide 80 . At this time, the worker feeds the taped component until the feed hole at the tip of the taped component meshes with the sprocket 82 of the feeding device 74 . Then, when the worker feeds the taped component until the feeding hole of the taped component meshes with the sprocket 82 of the feeding device 74 , the operator operates an operation button (not shown) provided on the stand 162 . The operation button is a button that activates the electromagnetic motor 84 of the tape feeder while being operated. By operating the electromagnetic motor 84 by operating the operation button, the taped component meshing with the sprocket 82 is moved to the supply position. sent towards. Therefore, the operator operates the operation button while confirming the taped component meshing with the sprocket 82 . Then, when the leading end of the taped component is delivered to a predetermined position, for example, the supply position, the operator stops operating the operation button. As a result, the taped component is attached to the tape feeder 70 in the loading device 150 . Further, when taped components are attached to the tape feeder 70 using the loading device 150, the component information and the identification information of the tape feeder are associated and stored in the memory 134 in the controller 30 of the electronic component mounting apparatus 10. By doing so, the registration information of the electronic component is registered. When the taped components are attached to the tape feeder, there is not only the work of feeding the taped components by the electromagnetic motor 84, but also the work of setting the top film peeled off from the taped components to the film peeling mechanism 86, and the like. , the operation of setting the top film, etc. will be omitted.

In this way, when the taped component is attached to the tape feeder, the taped component is attached to the tape feeder mounting base 110 of the electronic component mounting apparatus 10, whereby the electronic component is transferred from the taped component attached to the tape feeder. is supplied and the component mounting work is executed. Therefore, when the tape feeder is mounted on the tape feeder mounting base 110 of the electronic component mounting apparatus 10, the electronic component verification operation is performed. Specifically, when the tape feeder is mounted on the tape feeder mounting base 110 , the tape feeder is electrically connected to the control device 30 of the electronic component mounting apparatus 10 . At this time, the controller 130 of the control device 30 acquires the identification information of the tape feeder from the tape feeder. Then, the controller 130 extracts the identification information of the tape feeder mounted on the tape feeder mounting base 110 from the identification information of the tape feeders stored in the memory 134 . Subsequently, the controller 130 identifies component information stored in the memory 134 in association with the extracted tape feeder identification information. Then, the controller 130 confirms whether or not the type of the electronic component indicated by the specified component information matches the type of the electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10. Perform verification work on parts. Then, when the type of electronic component indicated by the component information matches the type of electronic component to be mounted in the mounting work by the electronic component mounting device 10, the mounting work by the electronic component mounting device 10 is executed. . This ensures proper component mounting work. Thus, in the electronic component mounting apparatus 10, the verify operation of the electronic component of the tape feeder mounted on the tape feeder mounting base 110 is performed.

However, if the tape feeder is mounted on the tape feeder mounting base 110 immediately after the taped component is mounted on the tape feeder on the kitting stand 152, the possibility that the reel has been replaced is low. On the other hand, when the tape feeder is mounted on the tape feeder mounting base 110 after a certain amount of time has elapsed since the taped components were mounted on the tape feeder on the kitting stand 152, the reel is replaced. likely to be. In other words, there is a high possibility that the reel has been replaced after the registration information of the electronic component was registered. In this way, when the reel is replaced after the registration information of the electronic component is registered, and the tape feeder with the replaced reel is mounted on the tape feeder mounting base 110, the verify operation cannot be performed properly. .

Therefore, in the conventional method, the registration information is erased when a predetermined time has passed after the registration information of the electronic component is registered. For this reason, when a predetermined time has passed after the registration information of the electronic component is registered, the verify operation of the electronic component is performed after re-registering the registration information of the electronic component. In this way, after the registration information of the electronic component is re-registered, the verify operation of the electronic component is executed, thereby ensuring an appropriate verify operation. However, re-registration of registration information of electronic components is a burden on the operator. In particular, if the kitting stand 152 stores the tape feeders after the taped components have been attached to the tape feeders, re-registration of electronic component registration information for many tape feeders is required. This is a heavy burden on workers. Further, some workers may avoid re-registration of registration information of electronic components and may not perform verification work itself.

In view of this, in the electronic component mounting apparatus 10, even after a predetermined period of time has elapsed after the electronic component registration information has been registered, the verification operation is performed without erasing the registration information. However, in order to ensure proper verification work, it is determined whether or not the reel has been replaced based on the detected value by the encoder of the tape feeder.

Specifically, as described above, when the taped components are attached to the tape feeder on the kitting stand 152, the control device 154 transmits the component information and the identification information of the tape feeder to the control device 30, and the control device 30 The part information and the tape feeder identification information are stored in the memory 134 as registration information. At this time, the control device 154 transmits not only the part information and the identification information of the tape feeder, but also the detection value of the encoder 85 when the taped part is attached to the tape feeder to the control device 30 . Specifically, the control device 154 acquires the detection value of the encoder 85 when the attachment of the taped component to the tape feeder is completed (hereinafter referred to as "component attachment detection value"). In other words, when the attachment of the taped components to the tape feeder is completed, the electromagnetic motor 84 does not operate, so the control device 154 acquires the detection value of the encoder 85 after the attachment of the taped components to the tape feeder is completed. do. Then, the control device 154 transmits to the control device 30 the acquired detection value of the encoder 85 , that is, the detection value at the time of component installation, the component information, and the identification information of the tape feeder. Then, in the control device 30, the detection value at the time of component mounting, the component information, and the identification information of the tape feeder are associated with each other and stored in the memory 134. FIG. As a result, the detection value at the time of mounting the component, the component information, and the identification information of the tape feeder are registered as the registration information. This registered information is not erased even after a predetermined period of time has passed.

Further, when the tape feeder is mounted on the tape feeder mounting table 110 of the electronic component mounting apparatus 10 and electrically connected to the control device 30 of the electronic component mounting device 10, the controller 130 of the control device 30 controls the tape from the tape feeder. Get feeder identification information. Further, the controller 130 acquires the detected value of the encoder 85 (described as "detected value at the time of attachment") from the tape feeder. Then, the controller 130 extracts the identification information of the tape feeder mounted on the tape feeder mounting base 110 from the identification information of the tape feeders stored in the memory 134 . Subsequently, the controller 130 identifies the detection value at the time of component attachment stored in the memory 134 in association with the extracted identification information of the tape feeder. Then, the controller 130 compares the component mounting detection value stored in the memory 134 with the mounting detection value acquired from the tape feeder mounted on the tape feeder mounting base 110 . As described above, the encoder 85 is an absolute encoder, so as long as the electromagnetic motor 84 does not rotate, the rotation angle detected by the encoder 85 will remain unchanged even after the power supply to the electromagnetic motor is cut off. ,It does not change. Therefore, if the detected value at the time of component attachment and the detected value at the time of attachment are the same, it is estimated that the electromagnetic motor 84 is not operating. Further, when the reel 72 in the tape feeder is replaced, the taped component of the replaced reel 72 must be attached to the tape feeder, so the electromagnetic motor 84 is operated by feeding the taped component. In other words, when the detected value at the time of component mounting and the detected value at the time of mounting are the same, it is estimated that the reel 72 has not been replaced in the tape feeder. On the other hand, when the detected value at the time of component mounting differs from the detected value at the time of mounting, it is presumed that the reel 72 has been replaced in the tape feeder.

Therefore, if the detected value at the time of component mounting and the detected value at the time of mounting are the same, the controller 130 executes verification work. That is, the controller 130 identifies the component information stored in the memory 134 in association with the tape feeder identification information extracted from the tape feeder identification information stored in the memory 134 . Then, the controller 130 confirms whether or not the type of the electronic component indicated by the specified component information matches the type of the electronic component to be mounted in the mounting operation by the electronic component mounting apparatus 10. Perform verification work on parts. In this way, when the detected value at the time of mounting the component and the detected value at the time of mounting are the same, that is, when it is estimated that the reel 72 has not been replaced in the tape feeder, performing the verifying operation enables an appropriate Verification work can be secured.

On the other hand, if the detected value at the time of component mounting differs from the detected value at the time of mounting, it is estimated that the reel 72 has been replaced in the tape feeder, so the controller 130 displays a warning screen on the display device 136 . This warning screen displays a comment prompting re-registration of the component information because the reel has been replaced in the tape feeder mounted on the tape feeder mounting base 110 . As a result, it is possible to prevent the supply of electronic components from the reel 72 that has been replaced after the component information is registered, and it is possible to secure an appropriate component mounting operation.

Note that the controller 130 of the control device 30 has a first acquisition section 180, a second acquisition section 182, and a determination section 184, as shown in FIG. The first acquisition section 180 is a functional section for acquiring, via the kitting stand 152, the detection value of the encoder 85 when taped components are attached to the tape feeder. The second acquisition unit 182 is a function for acquiring, via the electronic component mounting apparatus 10, the detection value of the encoder 85 when the tape feeder with the taped components mounted thereon is mounted on the tape feeder mounting base 110. Department. The judging section 184 is a functional section for judging whether or not the reel 72 in the tape feeder needs to be replaced based on the detection value at the time of component mounting and the detection value at the time of mounting.

In the first embodiment, whether or not the reel should be replaced is determined based on the detection value of the encoder 85 of the feeding device 74 of the tape feeder. Whether or not the reel needs to be replaced is determined based on the opening and closing. Specifically, in the second embodiment, a tape feeder 200 shown in FIG. 5 is used. Since the tape feeder 200 has almost the same structure as the tape feeder 70 of the first embodiment except for the reel cover 202, the description of the structure other than the reel cover 202 is omitted, and the same reference numerals as the structure of the tape feeder 70 are used. .

A housing 206 of the tape feeder 200 is formed with a reel storage section 79 that opens on the side. The reel cover 202 has a generally flat plate shape, and is arranged so as to block the opening of the reel housing portion 79 to the side surface of the housing 206 . Also, the reel cover 202 is swingably supported by a pair of hinges 208 at its upper end. By swinging the reel cover 202 downward, the reel cover 202 closes and closes the reel housing portion 79 . On the other hand, as shown in FIG. 6, by swinging the reel cover 202 upward, the reel cover 202 is opened and the reel housing portion 79 is opened. Therefore, when the reel 72 is stored in the reel storage portion 79 , the reel 72 can be taken out from the reel storage portion 79 by opening the reel cover 202 . Further, when the reel 72 is not stored in the reel storage portion 79 , the reel 72 is stored in the reel storage portion 79 by opening the reel cover 202 . Then, when the tape feeder 200 housing the reel 72 is used, the reel cover 202 is closed. Therefore, when replacing the reel 72, the reel cover 202 is always opened and closed.

The tape feeder 200 also incorporates a detection sensor 210 that detects opening and closing of the reel cover 202 and a memory 212 that stores the detection result of the detection sensor 210 . Further, the tape feeder 200 also incorporates a battery 214 that supplies power to the detection sensor 210 and the memory 212 . As a result, even when the reel cover 202 is opened and closed in the tape feeder 200 in the non-powered state, the opening and closing of the reel cover 202 is detected by the detection sensor 210, and the detection result of the detection sensor 210 is stored in the memory 212. be done. In the memory 212, when the opening/closing of the reel cover 202 is detected by the detection sensor 210 and the detection result of the detection sensor 210 is stored in the memory 212, the open/close flag is turned ON, and the opening/closing of the reel cover 202 is detected. When not detected by the detection sensor 210, the open/close flag is turned off.

When taped components are attached to the tape feeder 200 having such a structure using the kitting stand 152, the reel cover 202 may be opened and closed. In such a case, the opening and closing of the reel cover 202 is detected by the detection sensor 210 and the detection result is stored in the memory 212 . That is, the open/close flag is turned ON in the memory 212 . Also, when the tape feeder 200 is set on the kitting stand 152 and the barcode attached to the reel is read by the code reader 176, the control device 154 transmits the component information and the identification information of the tape feeder 200 to the control device 30. Send to Thereby, the registration information of the electronic component is registered in the control device 30 . After transmitting the component information and the identification information of the tape feeder 200 to the control device 30 , the control device 154 outputs a command to erase the memory 212 to the tape feeder 200 . Thereby, the detection result by the detection sensor 210 stored in the memory 212 is erased. In other words, after the electronic component registration information is registered, the open/close flag in the memory 212 is turned off. Therefore, the open/close flag of the memory 212 is kept OFF unless the reel cover 202 of the tape feeder 200 is opened/closed after the electronic component registration information is registered. On the other hand, if the reel cover 202 of the tape feeder 200 is opened and closed even once after the electronic component registration information is registered, the open/close flag of the memory 212 is turned ON.

Then, when the tape feeder 200 is mounted on the tape feeder mounting table 110 so as to use the tape feeder 200 for the mounting work in the electronic component mounting apparatus 10 , the controller 130 of the control device 30 acquires identification information from the tape feeder 200 . do. At this time, the controller 130 acquires not only the identification information from the tape feeder 200 but also information stored in the memory 212, that is, information indicating whether the open/close flag is ON or OFF. At this time, if the open/close flag is OFF, the reel cover 202 of the tape feeder 200 has never been opened/closed since the registration information of the electronic component was registered. presumed not. Therefore, when the open/close flag is OFF, the verification work is executed according to the procedure described above. On the other hand, if the open/close flag is ON, it is presumed that the reel cover 202 of the tape feeder 200 has been opened/closed after registration of the electronic component registration information, and that the reel 72 has been replaced in the tape feeder. Therefore, when the opening/closing flag is ON, the warning screen described above is displayed on the display device 136 . As a result, the same effect as in the first embodiment can be obtained in the second embodiment as well.

tape feeders

70 and 200 are employed as feeders for supplying components from taped components, but it is possible to employ various feeders. Specifically, for example, it is possible to adopt various feeders such as a tape feeder that feeds lead components from taped components in which lead components such as axial lead components and radial lead components are taped.

Also, in the above embodiment, the absolute encoder 85 that detects the rotation angle of the electromagnetic motor 84 is employed, but an incremental encoder may be employed. However, since the incremental encoder detects the relative rotation angle of the electromagnetic motor, the tape feeder must be provided with a memory for storing the rotation angle and a battery for supplying power to the memory.

Also, in the above embodiment, a kitting stand 152 is employed as a device for attaching taped components to the tape feeder. In other words, a device is employed in which an operator feeds the tip of the taped component to a predetermined position of the tape feeder and operates an operation button to attach the taped component to the tape feeder. On the other hand, a so-called auto-loading device may be employed that automatically feeds the tip of the taped component to a predetermined position of the tape feeder and also automatically feeds the taped component.

In addition, in the above embodiment, the memory 134 for storing registration information and the like is provided in the control device 30, but it may be provided in the cloud, a host management device that manages the electronic component mounting device 10, or the like.
