Description

  The present invention performs preparatory work of blood collection tubes in the blood collection step in the previous step of blood collection inspection, and uses an endless feeding belt to suspend the blood collection tubes (including test tubes). Adopting a modular blood collection tube stocker that is suspended and held and can be easily detached, and selects different types of blood collection tubes from the modular stocker according to a blood collection instruction from a doctor. The present invention relates to a blood collection tube preparation device having a small and simple structure and excellent mobility, which can be attached with a label printed with blood collection information such as instruction contents, and accommodate the blood collection tube after labeling in a tray.

In blood testing departments in hospitals, clinics, and other medical institutions, blood collection workers (such as nurses) collect blood from patients into blood collection tubes and transport them to the examination department. In blood tests, many types of blood collection tubes are prepared according to the blood test items, and usually, a plurality of types of tests are performed on one patient at the same time. Therefore, a plurality of types of blood collection tubes are automatically prepared by a blood collection tube preparation device for one patient. In the blood collection room, it is natural to handle a large number of patients, and each blood collection tube prepared by the blood collection tube preparation device is affixed with a label printed with a barcode such as patient information and blood collection test information. .
In addition, a blood collection reception slip on which a barcode such as a reception number is printed is issued to the patient at the time of blood collection reception. At the time of blood collection work, the contents of these labels and reception slips are read by an optical device such as a barcode reader so that the patient and blood collection tube are not mistakenly taken.

As a technique for automating such blood collection work and supporting the blood collection work, there is a technique disclosed in Patent Document 1. The technique of Patent Document 1 uses an endless belt driving device that is rotationally driven in a vertical direction (vertical direction). In this belt drive device, the belt width is set to be equal to or greater than the length of the blood collection tube, and has a caterpillar-shaped partition plate that protrudes from the belt surface in the outer diameter direction. A single blood collection tube accommodating portion (stock portion) is provided between them, and a large number of blood collection tube accommodating portions are formed on one belt surface. In this case, one belt driving device is set to accommodate the same type of blood collection tube. A stocker mechanism using a belt driving device that accommodates the blood collection tube in such a caterpillar system is arranged in a plurality of stages in the vertical direction so that a plurality of types of blood collection tubes can be handled.
Based on the blood collection order information from the doctor, the blood collection tubes necessary for the patient's blood collection are taken out from the corresponding blood collection tube stocker mechanism, and the information related to the patient's blood collection is printed on the label using the label printing / pasting means. The label is attached to the extracted blood collection tube. Then, the blood collection tube after labeling is transferred to the blood collection tube collection unit by the discharging means, and is stored in the tray for each patient by the blood collection tube collection unit.

In such a blood collection tube preparation device, there is a problem in that the size in the height direction becomes considerable due to the stocker mechanism portion being stacked one above the other, and the device itself is increased in size.
On the other hand, as a method for solving the above-mentioned conventional problems, it is conceivable to use, as a stocker, a technique for conveying a product similar to the shape of a blood collection tube as shown in Patent Document 2 and Patent Document 3 in a hanging manner. . These transport technologies use an annular collar (ring) provided near the mouth of a resin bottle or the like, and an attachment that can engage and support the ring on the transport belt between the two transport belts on the left and right. A ring such as a resin bottle is locked between the pair of attachments and the attachments facing each other and transported in a suspended state.

This makes it possible to supply rarely used blood collection tubes and special-sized blood collection tubes through the opening G individually to the printing and pasting means.

  Next, each device and mechanism constituting the blood collection tube preparation apparatus A will be described individually. First, the blood collection tube stocker 1 will be described with reference to FIGS. 5 is a plan view of the stocker 1, FIG. 6 is a side view thereof, FIG. 7 is a longitudinal sectional view thereof, and FIG. 8 is an enlarged plan view of a stopper. As shown in the longitudinal cross-sectional view of FIG. 7, the blood collection tube stocker 1 according to this embodiment is configured to fold a thin metal plate such as stainless steel, aluminum alloy, steel plate, etc., and to have a U-shaped cross-section passage (groove). ). The entire blood collection tube stocker 1 is configured as a single module M by connecting and connecting the constituent members to the housing. Therefore, replacement and repair of the blood collection tube stocker 1 can be performed in a one-touch manner with the module M as a unit, and remote module maintenance and replacement work can be performed by sending back only the module M. Moreover, it is not necessary to stop the blood collection work by preparing a substitute for the module M in advance. Further, by changing the width dimension of the passage (groove), it is possible to cope with the size (diameter) of the blood collection tube. By preparing a module M for each size, it is possible to It is also possible to respond quickly to various types of blood collection tubes.

As shown in the plan view of FIG. 5, the blood collection tube stocker 1 has an endless feed belt 2 suspended between a driven pulley 8A and a driving pulley 8B that are arranged flat on both ends. The feed belt 2 is a so-called toothed belt in which a large number of protrusions 9 are provided on the inner surface side where the forward feed belt 2A and the return feed belt 2B face each other. By using a toothed belt, slipping between the driving pulley 8B is eliminated, and the driving force of the driving pulley 8B can be reliably transmitted to the feed belt 2. Of course, the feed belt 2 may be a flat belt.

A blood collection tube holding member 3 disposed along the belt is provided in a space region between the forward side feed belt 2A and the return side feed belt 2B of the feed belt 2. Thereby, a space (groove) for accommodating the blood collection tube 4 is formed between the forward feeding belt 2A and the blood collection tube holding member 3. The blood collection tube holding member 3 is a guide frame having a smooth upper end surface such as a rail or plate member, and the height of the upper end surface is the same as the height of the upper end surface of the feed belt 2. Is set.

  Thus, the dimension of the groove width formed between the distal end surface of the projection 9 of the forward feeding belt 2A and the blood collection tube holding member 3 is the same as or slightly larger than the outer diameter of the blood collection tube 4 (maximum (About 1 mm). The interval between the groove widths can be varied according to the size of the outer diameter of the blood collection tube 4 to be stocked. For changing the size, as one method, an attachment stay (not shown) of the blood collection tube holding member 3 is moved to a long hole and a screw so that the blood collection tube holding member 3 can be translated relative to the forward feed belt 2A. It is sufficient to adopt means for fixing to the casing body by the above method, and the dimensions can be adjusted continuously. As another method, modules M having different groove widths may be prepared in advance. The sizes of blood collection tubes 4 are generally 13 mm and 16 mm in diameter for biochemical tests, immunological tests, blood glucose tests, hematology tests, coagulation tests, etc. There are those with a diameter of 8 mm.

As shown in FIGS. 6 and 7, the blood collection tube 4 is composed of a tube-shaped blood collection tube main body 4A and a cap 10, and the lower end surface of the cap 10 has an outer diameter dimension larger than the outer diameter dimension of the blood collection tube main body 4A ( A dimension larger than the groove width). As shown in FIG. 7, the blood collection tube 4 has the lower end surface facing the cap 10 placed on the upper end surface of the feeding belt 2 </ b> A on the forward side and the upper end surface of the blood collection tube holding member 3. Suspended and held. That is, the blood collection tube 4 is stocked in a suspended manner. The driving force of the feed belt 2 is transmitted to the blood collection tube 4 through the joint portion of the lower end surface of the cap 10 placed on the forward feed belt 2A. The lower end surface of the cap 10 on the opposite side only slides between the upper end surface of the blood collection tube holding member 3.

As shown in FIG. 7, on the back side of the forward side feed belt 2A, the members constituting the housing of the module M also serve as a backup member, so that the intermediate belt does not bend. As a backup member for the forward feed belt 2A, a backup member configured in the same manner as the blood collection tube holding member 3 as a guide frame may be used. By backing up the back side of the forward feed belt 2A, the upper end surface of the belt 2A is surely brought into contact with and joined to the lower end surface of the cap of the blood collection tube 4. Accordingly, the forward feed belt 2A does not deviate from the lower end surface of the cap 10, and the forward feed belt 2A can reliably feed (feed) the suspended blood collection tube 4 to the blood collection tube 4. It is.

  On the terminal end side of the blood collection tube holding member 3, a discharge portion 12 for the blood collection tube 4 is provided. The discharge portion 12 is provided in a space region between the terminal end side of the blood collection tube holding member 3 and the pulley 8A. When the blood collection tube 4 reaches the terminal end side of the blood collection tube holding member 3, the lower end surface of the cap 10 is released from the engagement with the blood collection tube holding member 3 and naturally falls due to its own weight.

Incidentally, first and second stoppers 5 and 6 are provided at positions facing the discharge portion 12. These first and second stoppers 5 and 6 are, as best shown in the plan view of FIG. 8, the arms 14 and 15 which are pivotally supported by the same shaft 13 so that the intermediate portion can swing freely. A bifurcated bar-like projection is provided on the lower surface on one end side with 5A, 5B and 6A, 6B standing upright. In the first and second stoppers 5 and 6, the portions where the rod-like protrusions 5A, 5B and 6A, 6B are provided, the portions bent in an L shape in a plan view enter each other and do not interfere with each other. It is made like that. The first stopper 5 is configured to be able to advance and retreat so as to be able to contact the front side of the cap of the leading blood collection tube 4, and the second stopper 6 is a cap for the leading and second blood collection tubes 4, 4. It is configured to be able to advance and retreat with respect to the gap formed between the two.

Further, rods 16A, 17A of solenoids 16, 17 are connected to the lower surfaces of the arms 14, 15 at the other end side. In this case, the solenoids 16 and 17 have the same outer diameter as that of the ballpoint pen for the purpose of miniaturization. When the power is turned on, the rods 16A and 17A retreat, and the arms 14 and 15 are shown in FIG. As shown by a chain line 2, the head is swung to the raised position. The solenoids 16 and 17 are normally set to operate alternately. Return springs (tension springs) 18 and 19 are attached between the pivots 13 of the arms 14 and 15 and the rod-shaped protrusions 5A and 5B and 6A and 6B, respectively. This is for the arms 14 and 15 to return to the horizontal posture by the pulling force of the return springs 18 and 19 when the power of the solenoids 16 and 17 is turned off. The return springs 18 and 19 also serve to prevent the falling blood collection tube 4 from jumping forward.

In this embodiment, as shown in FIGS. 1 and 9, six rows of hanging-type blood collection stockers 1 of the suspension system configured as described above are provided side by side. Below the discharge unit 12, a single conveyor belt 20 disposed in a direction perpendicular to the conveyance direction of the feed belt 2 is disposed, and the blood collection tubes 4 that are dropped and supplied from each of the six rows of stockers 1. Is conveyed from the left side of FIGS. 1 and 9 toward the right side by the conveyance belt 20. At this time, since the engagement of the blood collection tube 4 with the lower end surface of the cap 10 is released on the terminal end side of the blood collection tube holding member 3, the cap 10 side is inclined to the side released from the blood collection tube holding member 3. As a result, as shown by the chain line in FIG. 9, the bottom side of the blood collection tube 4 is always aligned toward the front side in the transport direction, and in this state, is dropped and supplied onto the transport belt 20.

In the embodiment of FIG. 9, the conveyor belt 20 is composed of one continuous belt. However, the conveyor belt 20 is divided into the area of the stocker 1 and the area of the label printing means 7 and is composed of two conveyor belts. It is also possible to enable the blood collection tube 4 to automatically transfer between the two conveying belts. In this case, the blood collection tube preparation device can be separated into a stocker device and a label printing / applying device, so that the stocker device can be used independently and maintenance can be performed separately. Convenient.

  An arrival detection plate 21 for the blood collection tube 4 is provided on the end side of the conveyor belt 20. In a normal state, the arrival detection plate 21 stands by in a slanted posture as shown by a chain line in FIG. 9, and when the blood collection tube 4 is fed, the arrival detection plate 21 is pressed by this to stand upright as shown by a solid line. At the same time, the stop position of the blood collection tube 4 is determined. The arrival detection plate 21 has a U-shaped bent portion, and in an inclined standby state, the irradiation light of a detection sensor (not shown) composed of a light emitter / receiver such as an infrared sensor or a photo sensor is blocked, In the upright state where the blood collection tube 4 has arrived, the light emitted from the projector is received by the light receiver. Further, as shown in FIGS. 9 and 10, a slider 22 for cutting out the blood collection tube 4 that reciprocates in the direction orthogonal to the conveyance direction of the conveyance belt 20 is provided on the side surface portion of the stop position of the blood collection tube 4. In addition, the blood collection tube 4 is pushed out from the conveying belt 20 and dropped and supplied to the attaching position of the label attaching device 7.

  In addition, a direction detection means for detecting the direction of the blood collection tube 4 is provided immediately before the arrival detection plate 21 (not shown). This is so that when the cap 10 is accidentally brought into contact with the arrival detection plate 21 and stopped, the irradiation light from the projector is blocked by the cap 10 and the direction of the blood collection tube 4 can be detected. Is.

  As shown in FIG. 10, the label sticking device 7 has a label supply roll 23 stuck on a continuous release paper and a take-up roll 24 for winding the release paper. The label fed from the supply roll 23 and the release paper are folded back and moved at an acute angle, so that only the strong label (more elastic than the release paper and less likely to break) is peeled from the release paper. The label goes straight and is supplied to the affixing means 29 side, and only the remaining release paper after that is taken up by the take-up roll 24. A printing device 25 for printing patient information and the like on the label is disposed on the upstream side of the peeling portion. The information to be printed is obtained from these databases or hard disks by connecting the control unit of the blood collection tube preparation device to a computer such as a higher-level medical system or a computer terminal of a doctor through an interface of a built-in board computer (CPU). It is made to do. Further, a sticking means 29 including a driving roller 26, a supporting roller 27, and a pressure roller 28 that can be moved forward and backward is disposed in the traveling direction of the label peeled from the release paper. Further, a placing portion for the tray 30 is provided obliquely below the sticking means 29.

  As shown in FIGS. 1 to 3 and 10, a built-in multipurpose printer 31 is disposed at a position facing the tray 30 next to the label sticking device 7 and the printing device 25. The multipurpose printer 31 is for printing out a blood collection instruction and putting it in the tray 30, for example. In addition, if it is unclear whether the patient is ready to collect blood in a hospital ward, etc., the label is not attached to the blood collection tube. Only the printing is performed by the separate printer 31, and the label is discharged to the tray 30. In this case, it is possible to directly collect blood at the bedside of the patient according to the state of the patient, and attach the manual label to the blood collection tube after blood collection. If the patient is unable to collect blood, the hand-pasted label may be left in the tray 30.

  Further, as shown in FIGS. 3 and 10, the label sticking device 7 and the printing device 25 and the multipurpose printer 31 are mounted on the slide table 32 as a unit, and are electrically connected (coupler) and By removing the positioning lock mechanism or the like, it can be pulled out of the apparatus main body 33. Therefore, when the label sticking device 7 and the printing device 25 and the separately placed printer 31 are out of order, there is an advantage that quick repair can be performed only by replacing the failed device. The label sticking device 7 and the printing device 25 and the separately placed printer 31 can use commercially available general-purpose products and have an advantage that they can be supplied at low cost. Further, these devices can be easily maintained because they can be pulled out of the apparatus main body 33 for maintenance.

  Next, an operation mode of the blood collection tube preparation apparatus A configured as described above will be described. First, modules M of the blood collection tube stocker 1 for stocking different types of blood collection tubes are set in the six rows of mounting portions of the stocker installation portion B provided on the upper surface of the apparatus main body 33. The module M may be fixed by a screw fixing method or another fixing method such as a one-touch clip method. Thereafter, different types of collection are performed manually in each groove (stock portion of the collection tube 4) formed between the collection tube holding member 3 of each collection tube stocker 1 and the forward feed belt 2A. The blood vessel 4 is set. In order to set the blood collection tube 4, it is only necessary to insert the blood collection tube 4 into the groove from the bottom side. Thereby, the opposing lower end surface of the cap 10 of each blood collection tube 4 is placed across the upper end surface of the blood collection tube holding member 3 and the upper end surface of the forward feed belt 2A, and is suspended and held by this. In the state before the operation starts, the rod-like protrusions 5A and 5B of the first stopper 5 of the blood collection tube preparation device abut against the front side of the cap 10 of the leading blood collection tube 4 and restrain its forward movement. . Further, the rod-like protrusions 6A and 6B of the second stopper 6 enter the gaps 31 and 31 formed on the left and right side surfaces formed between the caps 10 and 10 of the blood collection tubes 4 and 4 located at the top and second, respectively. The forward movement of the second blood collection tube 4 is restricted.

  In such a state, the power switch of the apparatus main body 33 is turned on, the CPU of the built-in board computer is operated to make the control software function, and blood collection information of a patient to collect blood is obtained from a host computer or a doctor's computer terminal. To do. Note that the control unit (firmware) of the blood collection tube preparation apparatus A has detected that the previous patient's tray 30 has been removed from the tray mounting unit E, and has newly added another for the patient. In a state where the tray 30 is not prepared, each device is not operated. This is in order to prevent the blood collection tube of the next patient from being introduced into the tray 30 of the previous patient so as not to be confused.

Based on the acquired information, the control unit determines the type of blood collection tube to be selected, and rotates the drive pulley 8B of the blood collection tube stocker 1 in which the corresponding type of blood collection tube 4 is stocked. These setting information and information obtained from the host are displayed on the touch panel display 37. By driving the drive pulley 8B, all the blood collection tubes 4 of the stocker 1 receive the feed of the forward feed belt 2A at the lower end surface of the cap 10 joined to the upper end surface of the forward feed belt 2A. . In this state, the movements of the first and second blood collection tubes 4 are restrained by the action of the first and second stoppers 5 and 6, respectively, so that all the blood collection tubes 4 remain stopped.

Next, the control unit of the blood collection tube preparation apparatus A turns on the solenoid 16 of the first stopper 5 of the corresponding stocker 1. As a result, the rod of the solenoid 16 is retracted, and the arm 14 is rotated in the counterclockwise direction in FIG. 10 with the pivot 13 as a fulcrum. Therefore, the rod-like projections 5A and 5B attached to one end side of the arm 14 are separated from the front side of the cap 10 of the leading blood collection tube 4, and the restraint of the leading blood collection tube 4 is released. The leading blood collection tube 4 is in a free state, and starts to advance from the stop position upon receiving the feed from the forward feed belt 2A. Eventually, the leading blood collection tube 4 reaches the discharge portion 12 on the terminal end side of the blood collection tube holding member 3 and the engagement with the blood collection tube holding member 3 is released, so that the cap 10 is removed from the blood collection tube holding member 3. 9 and is cantilevered by the forward feed belt 2A, and finally the engagement with the forward feed belt 2A is also released. As shown by the chain line in FIG. It falls onto the conveyor belt 20 by its own weight in a state where the head 20 is directed in the forward direction.

On the other hand, the solenoid 14 of the first stopper 5 is turned OFF, so that the arm 14 is returned to the original horizontal state by the return spring 18. Subsequently, the solenoid 17 of the second stopper 6 is turned on, and the arm 15 is rotated counterclockwise to the position indicated by the chain line in FIG. As a result, the rod-like protrusions 6A and 6B release the joint with the cap 10 of the second blood collection tube 4. Therefore, all of the remaining blood collection tubes 4 after the second are advanced by receiving the driving force of the forward feed belt 2A, and the new blood collection tube 4 at the head becomes the rod-shaped protrusion 5A of the first stopper 5, The front side of the cap 10 comes into contact with 5B and stops. Finally, the solenoid 17 of the second stopper 6 is turned OFF and returned to the horizontal state by the return spring 19, and the cap 10 between the newly-taken blood collection tube 4 and the second-positioned blood collection tube 4 is exchanged. It waits in this state until it enters the gap and a supply command for the next blood collection tube 4 is issued.

The conveyor belt 20 starts to be driven at the same timing as the solenoid 16 of the first stopper 5 is turned on. Therefore, the blood collection tube 4 dropped and supplied by its own weight is transported from the left direction to the right direction in FIG. 9 by the transport belt 20 and presses and urges the arrival detection plate 21. Even if the blood collection tube 4 is dropped and supplied to the conveyance belt 20 in an upright state, the conveyance belt 20 is driven from the left direction to the right direction in FIG. It will be transported with the side first. The blood collection tube 4 on the conveyor belt 20 has its bottom abutted against and pressed against the arrival detection plate 21 at the end of the conveyance path, and stopped by swinging the arrival detection plate 21 from an inclined posture to an upright posture. To come.
At this stop position, a direction detection sensor for the blood collection tube 4 (not shown) detects the cap 10 of the blood collection tube 4. When the cap is detected, it means that the cap has been transported with the head in the opposite direction. Since the cap is in the reverse direction, an alarm is issued by voice or a flashing signal of the light emitting element to notify the operator. The touch panel display 37 displays an error that the direction of the blood collection tube 4 is reverse. In this case, the operator may take out the blood collection tube 4 and change the direction to continue the operation.

When the arrival detection plate 21 is pressed and urged in an upright posture, arrival detection means such as a light projecting / receiving sensor works to detect that the blood collection tube 4 has been supplied. In response to this arrival detection signal, the slider 22 that reciprocates in the direction perpendicular to the conveying direction of the conveying belt 20 starts to move, pushes the arriving blood collection tube 4 laterally, and falls to the affixing means 29 side of the label affixing device 7. To supply. In the affixing means 29, the pressure roller 28 is in the retracted position, and advances when receiving the blood collection tube 4, and presses and biases the blood collection tube 4 toward the drive roller 26 and the support roller 27, thereby taking the drive force of the drive roller 26. It transmits to the blood vessel 4 and rotates the blood collection tube 4 in the circumferential direction.

On the other hand, the label printing device 25 prints necessary items of blood collection information such as a patient ID, a test item, a blood collection type, and a blood collection amount obtained from a host computer and a doctor's computer terminal on a label fed from the supply roller 23. . The contents to be printed are displayed on the touch panel display 37 and can be confirmed by the operator. As shown in FIG. 10, the label after printing is folded and moved at an acute angle, so that only the strong label goes straight and is naturally peeled off from the release paper. Then, the peeled label enters between the drive roller 26 and the outer peripheral surface of the blood collection tube 4 and is wound up, and is attached to the outer peripheral surface of the blood collection tube 4. After the label is applied, the pressure-collecting tube 4 is released from the affixing portion and dropped by its own weight when the pressure roller 28 is retracted and returned obliquely downward (lower left in FIG. 10), and is accommodated in the tray 30.

  Thus, preparation for one blood collection tube of one tube type is completed. Thereafter, if there is another required blood collection tube, the stocker 1 of that tube type is driven, and the above operation is sequentially repeated to house the blood collection tube 4 in the tray 30. Further, if there is a manually inserted blood collection tube, it may be supplied individually from the manually inserted opening provided on the left side surface of the apparatus main body onto the transport bell 20 and attached to the tray 30 by attaching a label. In this way, when preparation of blood collection tubes for all tube types requested by information from the host computer and doctor's computer terminal is completed, preparation of blood collection tubes for blood collection for one patient is completed. It will be. Thereafter, other patient blood collection tubes may be prepared in the same manner.

  By the way, this invention is not limited to embodiment mentioned above, A suitable change is possible. For example, the feeding belt 2 used for the blood collection tube stocker 1 has been described as a toothed belt, but may be a normal flat belt. Moreover, although the case where six blood-collecting-stockers 1 were provided side by side was demonstrated, six or less, such as 1, 2, 3, etc., may be sufficient and six or more may be sufficient. The number can be arbitrarily set according to the purpose. Since these blood collection tube stockers 1 can be set with respect to the apparatus main body 33 in a modular manner, the size of the blood collection tube can be easily changed even after shipment. In addition, a plurality of types of blood collection tubes 1 are prepared by changing the number of blood collection tubes that can be accommodated, such as 10 modules, 15 modules, and 20 modules. It can also be easily exchanged.

Furthermore, although the solenoids 16 and 17 have been described with respect to the case where the rod retracts during the ON operation, the solenoids 16 and 17 may be reciprocated between protrusion and retraction. In this case, the return springs 18 and 19 can be omitted.

Furthermore, the conveyor belt 20 is divided into the area of the stocker 1 and the area of the label applicator 7 so that the two conveyor belts are continuous so that the blood collection tube 4 can be transferred automatically. It is also possible. In this case, the external cover constituting the housing of the blood collection tube preparation device can be separated into the region of the stocker 1 and the region of the label sticking device 7, and specific maintenance work can be performed in each region. it can. It is also possible to configure the blood collection tube stocker device and the label attaching device 7 separately, sell the blood collection tube stocker device alone, and connect the both as an optional product to configure the blood collection tube preparation device. is there.

Furthermore, although the multipurpose printer 31 has been described as a built-in type, a multipurpose printer (sold separately) is placed on the side of the device A to print out a separate label by communication connection with the device A. Is also possible. The multi-purpose printer is installed next to the main printer 25. However, the multi-purpose printer may be installed in an arbitrary location as long as it does not interfere with other devices in the apparatus main body. The take-out port for the label and the like need not face the tray supply port.

Furthermore, the information and function key assignments and number displayed on the touch panel display 37, examples of button display, display contents of the setting state display unit 38, types of buttons to be selected, functions, and the like can be appropriately changed. Needless to say. In addition, the installation positions and layouts of the touch panel display 37 and the setting state display unit 38 can be appropriately changed.
