Title: Tape feeder, and method for displaying setting information in tape feeder

Description:
TECHNICAL FIELD 
     The present invention relates to a tape feeder used in an electronic component mounting device which mounts electronic component on a board and a method for displaying setting information which displays setting information of a tape feeding operation in the tape feeder. 
     BACKGROUND ART 
     In a component supply part provided in an electronic component mounting device which mounts electronic component on a board, a tape feeder provided with a component feed mechanism which conveys the electronic component held by a carrier tape to a taking out position by a component mounting mechanism is arranged for each of kinds of components (for instance, see patent literature 1). In the tape feeder, since operation parameters such as a feed speed or a feed pitch when the carrier tape is fed pitch by pitch are different respectively depending on the kinds of the components, the operation parameters are stored in a feeder storage part provided in the tape feeder. When a kind of production machine is switched to change the kind of the components as an object to be mounted during an operating process of an electronic component mounting system, the operation parameters of the kind of the components are written respectively in the feeder storage parts of the tape feeders. 
     The electronic component used in a production spot of a mounting board have the same standard for the kind of the component, however, provisions of items relating to the operation parameters for operating the tape feeder such as a material of the carrier tape for holding the component or a component arrangement pitch may be occasionally different. In such a case, in order to decide whether or not the tape feeder can be normally operated, the operation parameters which are already stored need to be recognized. The above-described recognition of the already set operation parameters is usually carried out through a data display function provided in a host system such as a host computer. 
     In recent years, the function of a tape feeder single body is made to be advanced and the tape feeder is used that has a structure provided with an individual display function. For instance, in an example disclosed in patent literature 1, a seven-segment type display device is provided in an operation side by an operator in a tape feeder so that the number of remaining component of the tape feeder or error codes showing contents of occurring errors may be displayed.

     SUMMARY OF THE INVENTION 
     Problems that the Invention is to Solve 
     When the tape feeder is used which has a highly advanced function and a progressive intelligence in view of a control as described above, the individual tape feeder is desired to recognize more versatile information including setting information such as the above-described already set operation parameters. However, in the usual technique including the example of the above-described patent literature, when an operation is to be carried out that the setting information set by the host system and written respectively in the tape feeders is recognized, the data display function provided in the host system needs to be used. Thus, a method inferior in working property is forced to be used that the recognition is separately carried out at a remote position from the actually used tape feeder. 
     Further, such recognition of the setting information is not necessarily limited to a case that all the tape feeders used in one device are set as objects, but there is a case that the setting information is sometimes desired to be recognized only for a part of the tape feeders. However, in the usual technique, when a display operation of the setting information is carried out by the host system, an operation for specifying the tape feeder as an object to be recognized needs to be carried out on a display device of the host system. Accordingly, for instance, when the setting information is desired to be individually displayed for the plurality of tape feeders, the display operation is hardly carried out in a flexible form. 
     Thus, it is an object of the present invention to provide a tape feeder and a method for displaying setting information in a tape feeder which can display the setting information in a flexible form and with a good working property. 
     Solution to Problem 
     According to one aspect of the invention, there is provided a tape feeder arranged in a component feed section of an electronic component mounting device which mounts electronic component on a board to feed a carrier tape holding the electronic component pitch by pitch, the tape feeder including: 
     a feeder control part which controls the tape feeder; 
     a feeder storage part which stores information used in a control process by the feeder control part; 
     a display part which displays information relating to a tape feeding operation by the tape feeder as setting information which is previously set and inputted and stored in the feeder storage part; and 
     a display switching part which switches the setting information displayed in the display part. 
     According to another aspect of the invention, there is provided a display method of setting information that changes setting information relating to a tape feeding operation in a tape feeder arranged in a component feed section of an electronic component mounting device which mounts electronic component on a board to feed a carrier tape holding the electronic component pitch by pitch, the tape feeder including a feeder control part which controls the tape feeder, a feeder storage part which stores information used in a control process by the feeder control part, a display part which displays information relating to the tape feeding operation by the tape feeder as the setting information which is previously set and inputted and stored in the feeder storage part, and a display switching part which switches the setting information displayed in the display part, the display method of the setting information in the tape feeder including: 
     a display process that displays the setting information stored in the feeder storage part in the display part in the tape feeder; and 
     a display switching process that switches the setting information displayed in the display part by the display switching part. 
     Advantage of the Invention 
     According to the present invention, each of the plurality of tape feeders arranged in the component feed section includes the feeder storage part which stores the information used in a control process by the tape feeder, the display part which displays the setting information previously set and inputted and stored in the feeder storage part and the display switching part which switches the setting information displayed in the display part.

     MODE FOR CARRYING OUT THE INVENTION 
     Now, an exemplary embodiment of the present invention will be described below by referring to the drawings. Initially, by referring to  FIG. 1 , a structure of an electronic component mounting system  1  will be described. The electronic component mounting system  1  includes a plurality of the same kinds of electronic component mounting devices (refer them simply as to “devices” in abbreviation, hereinafter) M 1 , M 2 , M 3 , M 4  and M 5  connected in series and has a function for mounting electronic component on a board to produce a mounting board. The board fed from an upstream side (an arrow mark a) to the electronic component mounting system  1  as an object to which the electronic component is mounted is delivered to a board conveying mechanism  3  through a conveying opening part A provided in the device M 1  located in the most upstream side and sequentially conveyed in a direction X (a board conveying direction) in the electronic component mounting system  1 . The loaded board serves as the object of component mounting operations respectively by the devices and the board after the component mounting operation is further unloaded to a device of a downstream side. 
     In the electronic component mounting system  1 , in the device M 1  to the device M 5  respectively, are arranged operation parts  2  in which the devices are respectively operated by machine operators and component feed sections  5  for feeding the electronic component to the devices. To the component feed sections  5 , carriages  8  are attached which hold a plurality of tape feeders  6  as component feeders for feeding the electronic component or tape reels  7  arranged in parallel. The tape feeder  6  feeds a carrier tape which holds the electronic component pitch by pitch to feed the electronic component to a below-described component mounting mechanism. The tape reel  7  winds and accommodates the carrier tape fed to the tape feeder  6 . 
     Now, structures of the device M 1  to the device M 5  will be described below by referring to  FIG. 2 . In  FIG. 2 , on a base  10 , the board conveying mechanism  3  is arranged in the direction X. The board  4  which is fed from an upstream side device and serves as the object of the component mounting operations by the devices is conveyed by the board conveying mechanism  3  and positioned and held in a position of the component mounting operation. In both sides of the board conveying mechanism  3 , the component feed sections  5  are provided. To the component feed sections  5 , a plurality of tape feeders  6  are attached. In one end part of the base  10  in the direction X, a Y-axis moving table  11  provided with a linear driving mechanism is horizontally arranged in a direction Y. To the Y-axis moving table  11 , X-axis moving tables  12  similarly provided with linear moving mechanisms are connected. To the X-axis moving tables  12 , mounting heads  13  are respectively attached so as to be movable in the direction X. 
     The mounting head  13  is a multiple string type head having a plurality (here, eight) of unit mounting heads  14 . The unit mounting heads  14  respectively suck and hold the electronic component by suction nozzles  14   a  (see  FIG. 4 ) attached to lower end parts. The Y-axis moving table  11  and the X-axis moving tables  12  form a head moving mechanism. The head moving mechanism is driven so that the mounting heads  13  move in the direction X and in the direction Y. Thus, the unit mounting heads  14  respectively take out the electronic component from the tape feeders  6  of the component feed sections  5  to move and mount the electronic component on the board  4  positioned by the board conveying mechanism  3 . 
     Accordingly, the Y-axis moving table  11 , the first X-axis moving table  12  and the mounting head  13  serve as a component mounting mechanism  40  (see  FIG. 7 ) which moves the mounting head  13  holding the electronic component by the head moving mechanism to move and mount the electronic component on the board  4 . Between the component feed section  5  and the board conveying mechanism  3 , a component recognition device  16  is arranged. When the mounting head  13  which takes out the electronic component from the component feed section  5  moves above the component recognition device  16 , the component recognition device  16  picks up an image of the electronic component held by the mounting head  13  to recognize the electronic component. 
     To the mounting head  13 , a board recognition camera  15  (see  FIG. 4 ) is attached which is located in a lower surface side of the X-axis moving table  12  and moves integrally therewith. When the mounting head  13  moves, the board recognition camera  15  moves to an upper part of the board  4  positioned by the board conveying mechanism  3  to pick up an image of the board  4  and recognize the board  4 . In a mounting operation of the electronic component on the board  4  by the mounting head  13 , a mounting position is corrected by considering the recognized result of the electronic component of the component recognition device  16  and the board recognized result of the board recognition camera  15 . 
     Now, referring to  FIG. 3 , will be described arrangements of the parts respectively in operating surfaces of the device M 1  to the device M 5 . In the operating surface, the operation part  2  is arranged in a vertical attitude in a side part of the component feed section  5 . In an upper part of the operation part  2 , a monitor  17  is arranged which is formed with a display device such as a liquid crystal panel. The monitor  17  displays previously set prescribed items such as an operation instructing screen. In a lower part of the monitor  17 , an operation panel  18  is provided in which the machine operator inputs an operation to a controller  27  (see  FIG. 7 ). In the operation panel  18 , are arranged operation buttons  18   a  for inputting various kinds of operations or an emergent stop button  18   b.    
     In the component feed section  5 , when the machine operator exchanges the carriage  8  or makes maintenance of the tape feeder  6 , the machine operator operates the tape feeder  6  or the operation button  18   a  in accordance with an instruction of the operation instructing screen. Further, on upper covers of the device M 1  to the device M 5  respectively, signal towers  9  protrude (also see  FIG. 1 ). Owing to a running out of component or an abnormal operation of a machine in each of the devices, when a treatment of the machine operator is necessary, the signal tower  9  turns on a signal lamp in a prescribed display pattern to inform the machine operator of the above-described situation. 
     As shown in  FIG. 4 , to the component feed section  5 , the carriage  8  is set which has the plurality of tape feeders  6  previously attached to a feeder attaching base  8   a . To a fixing base  10   b  provided in the base  10 , the feeder attaching base  8   a  is clamped by a clamp mechanism  8   b  so that a position of the carriage  8  is fixed in the component feed section  5 . In the carriage  8 , the tape reels  7  are held which accommodate the carrier tapes  20  holding the electronic component in winding states. The carrier tapes  20  pulled out from the tape reels  7  are fed pitch by pitch to component suction positions  5   a  by the suction nozzles  14   a  by the tape feeders  6 . 
     Now, referring to  FIGS. 5A ,  5 B and  5 C and  FIGS. 6A and 6B , a structure and a function of the tape feeder  6  will be described below. As shown in  FIG. 5C , the tape feeder  6  includes a feeder main body part  6   a  forming an entire configuration of the tape feeder  6  and an attaching part  6   b  which protrudes downward from a lower surface of the feeder main body part  6   a . Under a state that tape feeder  6  is attached to the feeder attaching base  8   a  with the lower surface of the feeder main body part  6   a  extended along the feeder attaching base  8   a , a connector provided in the attaching part  6   b  is fitted to the feeder attaching base  8   a . Thus, the tape feeder  6  is fixed and attached to the component feed section  5 . The tape feeder  6  is electrically connected to a controller  27  of each of the devices M 1  to M 5 . 
     In the feeder main body part  6   a , a tape travel path  6   c  opened to an upstream end part of the feeder main body part  6   a  in a tape feeding direction is provided to communicate with a suction position by the mounting head  13 . The tape travel path  6   c  has a function for guiding a tape feed of the carrier tape  20  (see  FIG. 5A ) pulled out from the tape reel  7  and introduced to the feeder main body part  6   a  from the upstream side of the feeder main body part  6   a  to the suction position by the mounting head  13 . 
     In the tape feed of the carrier tape  20  by the tape feeder  6 , a tape splicing operation is carried out that a terminal end part of a carrier tape  20 A which is already attached to the tape feeder  6  is joined to a leading end part of a new carrier tape  20 B which is pulled out from a new tape reel  7  replaced due to the running out of component by using a connection tape. Thus, every time that the tape reel  7  is replaced by the new tape reel due to the running out of component, a joint part J is formed by joining the two carrier tapes  20  together, so that the carrier tape  20  is not interrupted and fed by the tape feeder  6 . 
     As shown in  FIG. 5B , the carrier tape  20  includes, in a base tape  20   a  forming a tape main body, component pockets  20   b  which accommodate and hold the electronic component  21  and feed holes  20   d  provided at prescribed pitches for feeding the carrier tape  20  pitch by pitch. An upper part of the base tape  20   a  is sealed by a top tape  20   c  so as to cover the component pockets  20   b  in order to prevent the electronic component  21  from slipping out of the component pockets  20   b.    
     In the feeder main body part  6   a , a pitch feed mechanism  22  is built which feeds the carrier tape  20  pitch by pitch by a sprocket  25  arranged with an axis positioned horizontally in a downstream end part of the feeder main body part  6   a  in the tape feeding direction. The pitch feed mechanism  22  is provided with a tape feed motor  24  which rotates and drives the sprocket  25  and a feeder control part  23  which controls the tape feed motor  24 . When the tape feed motor  24  is driven under a state that feed pins (an illustration is omitted) provided on an outer periphery of the sprocket  25  are engaged with the feed holes  20   d  (see  FIG. 5A ) of the carrier tape  20 , the carrier tape  20  is fed pitch by pitch along the tape travel path  6   c.    
     In a process of the pitch feed operation, when the carrier tape  20  passes a joint detecting part  29 , the joint part J is detected by the joint detecting part  29  and a detected result is transmitted to the feeder control part  23 . The joint detected result shows a lot of the electronic component fed by the tape feeder  6 , namely, a switching timing of a group of component fed for a reel unit, and is not only recorded as component using history data, but also used as a trigger signal for resetting component remaining number data showing the number of component which can be fed by the tape reel  7  of the tape feeder  6 . 
     A front side of the sprocket  25  is a suction position where the electronic component  21  in the component pocket  20   b  is sucked and taken out by the suction nozzle  14   a  of the unit mounting head  14 . In an upper surface side of the feeder main body part  6   a  in the vicinity of the sprocket  25 , a tape pressing member  26  is arranged. In the tape pressing member  26 , a suction opening part  26   a  is provided correspondingly to the suction position by the suction nozzle  14   a . In an upstream end of the suction opening part  26   a , a top tape peeling part  26   b  is provided which peels the top tape  20   c.    
     The carrier tape  20  is fed pitch by pitch under a state that the carrier tape is pressed to the tape travel path  6   c  by the tape pressing member  26 . In a process that the carrier tape  20  travels below the tape pressing member  26 , the top tape  20   c  is turned about the top tape peeling part  26   b  and pulled out to an upstream side. Thus, in the upstream side of the suction position, the top tape  20   c  is peeled from the base tape  20   a . Thus, the electronic component  21  in the component pocket  20   b  (see  FIG. 5B ) is exposed upward in the suction opening part  26   a  so that the electronic component  21  may be taken out by the suction nozzle  14   a . Then, the top tape  20   c  peeled from the base tape  20   a  and turned back in a tape peeling position is guided obliquely downward, which is opposite to a pitch feeding direction, and sent to a tape recovery part (an illustration is omitted) provided in the upstream side of the feeder main body part  6   a  by a top tape feed mechanism  6   d  (see  FIG. 6B ). 
     As shown in  FIG. 6B , in the tape feeder  6 , on an upper surface of a downstream side (a left side in the drawing) to which the operator comes near during an operation, an operation unit  28  is arranged which is operated by the operator or gives information to the operator. As shown in  FIG. 6A , on an upper surface of the operation unit  28 , below described display devices and operating devices are arranged as well as an LED lamp  28   a  showing an operating state. Initially, a display part  28   b  is a simplified display device which can display symbols such as numerical characters or alphabets of about two characters. Here, two display elements of a 7 segment type are combined together. The operation unit  28  is connected to the feeder control part  23  in the tape feeder  6 , so that contents of a display are commanded through the feeder control part  23  by the controller  27  of each of the devices. 
     In the display part  28   b , are displayed previously set and prescribed items which are necessary for monitoring the operation of the tape feeder  6  or maintenance of the tape feeder  6  and can be simply displayed by the symbols. In the present exemplary embodiment, in the display items, are displayed various kinds of parameters in carrying out a mounting operation, that is, information relating to a tape feeding operation by the tape feeder  6  and a component taking out operation from the tape feeder  6  by the mounting head  13  of the component mounting mechanism  40  as setting information which is previously set, input and stored. 
     In the operation unit  28 , an operation input part  28   c  is provided together with the display part  28   b . The operation input part  28   c  has functions for displaying the above-described setting information in the display part  28   b , inputting a display operation for switching the displayed setting information and inputting a modification operation for modifying the displayed setting information as well as a function for inputting an operation for moving the tape feeder  6  by a manual operation. 
     In the present exemplary embodiment, the operation input part  28   c  includes a display switch button  28   d , a tape feed button  28   e , a tape return button  28   f  and a top tape winding button  28   g . The display switch button  28   d  is an operation button which switches an ON/OFF operation of the display part  28   b  or the display items of the above-described displayed setting information. Namely, when the display switch button  28   d  is pressed under a non-display state of the display part  28   b , the display part  28   b  is switched to a display state. After that, when the display switch button  28   d  is pressed in a previously set prescribed pattern, the display items of the setting information displayed in the display part  28   b  are switched. Every time the display switch button is pressed, a next display item is sequentially displayed in accordance with a previously set switching order. 
     Namely, in the present exemplary embodiment, the operation input part  28   c  is provided with the display switch button  28   d  which functions as a display switching button and serves as a display switching part which switches the setting information displayed in the display part  28   b  by operating the display switch button  28   d  by the operator. 
     The tape feed button  28   e  and the tape return button  28   f  are operation buttons which feed the carrier tape  20  in the tape feeder  6  by a manual operation. Namely, when the tape feed button  28   e  having an arrow mark attached in an advancing direction is operated, the carrier tape  20  can be fed in the advancing direction. When the tape return button  28   f  having an arrow mark attached in a retreating direction is operated, the carrier tape  20  can be fed in the retreating direction. The top tape winding button  28   g  is a manual operation button for winding the tap tape  20   c . When the top tape winding button  28   f  is operated, the top tape  20   c  peeled from the base tape  20   a  in the tape peeling position is guided to the tape recovery part by the top tape feed mechanism  6   d.    
     Further, the tape feed button  28   e  and the tape return button  28   f  are used as input buttons for modifying numerical data forming the above-described setting information. Namely, after the display item is selected by the display switch button  28   d , the tape feed button  28   e  and the tape return button  28   f  are operated so that a modification operation for adjusting the numerical data may be carried out. A structure of the display part  28   b  or the operation input part  28   c  in the operation unit  28  is arbitrary and may be suitably selected in accordance with the kind of the setting information or a desired operability. 
     Now, referring to  FIG. 7  and  FIG. 8 , a structure of a control system will be described below.  FIG. 7  shows a control function provided in a management computer  30  and a function of the controller  27  provided in each of the devices M 1  to M 5 . The management computer  30  includes a system control part  31 , a system storage part  32 , a modification process part  33  and an operation input part  34 . The system control part  31  controls an entire part of the electronic component mounting operation by the electronic component mounting system  1 . The system storage part  32  stores data for a production operation such as processing programs necessary for the component mounting operation carried out by the electronic component mounting system  1  or mounting data of the various kinds of boards. The modification process part  33  carries out a process for modifying the data stored in the system storage part  32  such as the data for the production operation in accordance with an instruction input carried out through the operation input part  34 . 
     The management computer  30  is connected to a communication part  35  provided in the controller  27  of the devices M 1  to M 5  through a LAN system L. The controller  27  includes a main body control part  36 , a main body storage part  37 , a display process part  38 , a mechanism driving part  39 , the component mounting mechanism  40 , an operation input part  41  and a modification process part  42 . Further, the devices M 1  to M 5  are respectively connected to the plurality of feeders  6  arranged in their component feed sections  5 . 
     The main body control part  36  is a processing calculator to control below-described parts such as the component mounting mechanism  40  in accordance with various kinds of programs or data stored in the main body storage part  37 . The main body storage part  37  stores information used in the control process by the main body control part  36 . The information includes mounting data  37   a , tape feed data  37   b  and component taking out data  37   c  as well as control process programs for carrying out the component mounting operation. The mounting data  37   a  is data which prescribes kinds of component to be mounted or component mounting positions and is stored for each of the kinds of the boards. 
     The tape feed data  37   b  is previously inputted as the setting information such as the operation parameters which prescribe the tape feeding operation by the tape feeder  6  or property data showing the property of the carrier tape as an object. Here, at least any one of a feed speed, a feed pitch and a material of the carrier tape  20  is included as the tape feed data. The component taking out data  37   c  shows the operation parameters such as a descending position or a descending height of the suction nozzle  14   a  when the electronic part is sucked and taken out from the tape feeder  6  by the suction nozzle  14   a  of the mounting head  13 . The data is previously transmitted from the system storage part  32  of the management computer  30  to each of the devices as the setting information and stored in the main body storage part  37 . 
     The display process part  38  carries out a process which allows the monitor  17  and the display part  28   b  to display prescribed items. The items displayed in the display part  28   b  include the above-described feed speed, the feed pitch and the tape material of the carrier tape  20 . The mechanism driving part  39  is controlled by the main body control part  36  to drive the component feed section  5 , the board conveying mechanism  3  and the component mounting mechanism  40 . Thus, the component mounting operation is carried out that the electronic component taken out from the tape feeders  6  arranged in the component feed section  5  are moved and mounted on the board  4  held by the board conveying mechanism  3 . 
     The operation input part  41  is an input device such as a keyboard or a touch panel provided in the monitor  17  and carries out an operation command for operating the device or an input operation when the already set setting information stored in the main body storage part  37  is modified. The modification process part  42  outputs a signal for modifying the setting information which is newly inputted through the operation input part  41  to the tape feeder  6  belonging to the device or other device and the management computer  30 . 
     Now, referring to  FIG. 8 , a structure of a control system of the tape feeder  6  will be described below. As shown in  FIG. 8 , the tape feeder  6  includes the feeder control part  23  which controls the tape feeder and the above-described operation unit  28 . Further, the feeder control part  23  includes a motor driving part  23   a , a feeder storage part  23   b  and a modification process part  23   c . In the operation unit  28 , the operation input part  28   c  and the display part  28   b  are provided as described above. The motor driving part  23   a  drives the tape feed motor  24  which feeds the carrier tape  20  pitch by pitch. The feeder storage part  23   b  stores information used in a control process by the feeder control part  23 . 
     The display part  28   b  displays the information relating to the tape feeding operation by the tape feeder  6  and the component taking out operation from the tape feeder  6  by the component mounting mechanism  40  as the setting information which is previously set and inputted and stored in the feeder storage part  23   b . The operation input part  28   c  carries out an input of a display operation for displaying the setting information in the display part  28   b  and an input of a modification operation for modifying the displayed setting information. The modification process part  23   c  outputs a signal for modifying the setting information stored in the main body storage part  37  and the feeder storage part  23   b  in accordance with the input of the modification operation. 
     As shown in  FIG. 7  and  FIG. 8 , in the electronic component mounting system  1 , the system storage part  32  arranged in the management computer  30 , the main body storage part  37  provided in each of the devices M 1  to M 5  and the feeder storage part  23   b  provided in each of the feeders  6  form a layered structure having the system storage part  32  set to the highest order. The layers respectively include the modification process part  33 , the modification process part  42  and the modification process part  23   c.    
     According to the structure, when the setting information is desired to be modified by setting the tape feeder  6  as an object of an input operation in each of the devices M 1  to M 5 , may be selected any of the modification of the setting information by setting an entire part of the electronic component mounting system  1  as an object, only the device as an object or only the tape feeder  6  as an object. Namely, the modification process part  23   c  of the tape feeder  6  can set the system storage part  32 , the main body storage part  37  and the feeder storage part  23   b  as the objects to selectively modify the setting information. It is to be understood that any of the management computer  30  or the devices M 1  to M 5  may be set as an object of an input operation to select the object for modifying the setting information in the same way. 
     In the devices M 1  to M 5  forming the electronic component mounting system  1 , the modification of the setting information, which relates to the tape feeding operation by the tape feeder  6  and the component taking out operation from the tape feeder  6  by the component mounting mechanism  40  as the previously set and inputted setting information, is as follows. Initially, in the tape feeder  6 , a display operation is inputted by the operation input part  28   c  to display the setting information stored in the feeder storage part  23   b  in the display part  28   b  arranged in the tape feeder  6  (a display process). 
       FIGS. 9A ,  9 B and  9 C show examples of the setting information displayed in the display part  28   b  as described above. Here, the setting information includes the feed speed, the feed pitch and the tape material of the carrier tape  20 . In  FIGS. 9A ,  9 B and  9 C, are displayed in the 7 segment type the characters, the symbols or the numerical characters respectively showing the feed speed, the feed pitch and the material of the tape. In a left side of  FIG. 9A , an alphabet L showing that the feed speed is low is displayed. In a left side of  FIG. 9B , the numerical character  2  showing the feed pitch is 2 mm is displayed. Further, in a left side of  FIG. 9C , an alphabet P showing that the material of the tape is paper is displayed. 
     Then, the modification of the display is inputted by the operation input part  28   c  to output the signal for modifying the setting information from the modification process part  23   c  (a modification process). In the modification process, any of the system storage part  32  arranged in the management computer  30 , the main body storage part  37  provided in each of the devices M 1  to M 5  and the feeder storage part  23   b  provided in each of the feeders  6  may be set as the object to selectively modify the setting information. Here, as shown in right sides of  FIGS. 9A ,  9 B and  9 C respectively, are displayed an alphabet H showing that the feed speed is modified to a high speed, the numerical character  4  showing that the feed pitch is modified from 2 mm to two times as long as 2 mm and an alphabet E showing that the material of the tape is a resin and embossed type. 
     When data is recognized or modified by setting other setting information as an object, the setting information displayed in the display part  28   b  is switched by the operation input part  28   c  having a function as the display switching part (a display switch process). After that, when the setting information needs to be modified, the same processes are repeatedly carried out. 
     As described above, in the electronic component mounting devices M 1  to M 5  and the tape feeders  6  shown in the present exemplary embodiment, each of the plurality of tape feeders  6  arranged in the component feed section  5  includes the display part  28   b  which displays the information relating to the tape feeding operation by the tape feeder  6  and the component taking out operation from the tape feeder  6  by the component mounting mechanism as the setting information which is previously set and inputted and stored in the feeder storage part  23   b , the operation input part  28   c  which carries out an input of the display operation for displaying the setting information in the display part  28   b  and an input of the modification operation for modifying the displayed setting information and the modification process part  23   c  which outputs the signal for modifying the setting information stored in the main body storage part  37  and the feeder storage part  23   b  in accordance with the input of the modification operation. Thus, the display and the modification operation of the setting information can be carried out in a flexible form and with a good working property. 
     This application is based on Japanese Patent Application (JPA No. 2012-091577) filed on Apr. 13, 2012, and contents thereof are incorporated herein as a reference.
