Description

[Technical field]

[0001] The present invention relates to a currency processing device. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there has been known a currency processing device that includes an upper unit and a lower unit that are retractably disposed within a housing, in which currency is transferred between the upper unit and the lower unit (see, for example, Patent Document 1).

[0003] In the currency processing device disclosed in Patent Document 1, when the lower layer unit is pulled out from the housing, rollers provided on the underside of the lower layer unit support the weight of the lower layer unit, allowing the lower layer unit to be pulled out stably. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-328479 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the currency processing device disclosed in Patent Document 1, the rollers supporting the lower layer unit are positioned higher than the rollers supporting the housing, so that when the lower layer unit is stored in the housing, the rollers supporting the lower layer unit are not in contact with the installation floor, and when the lower layer unit is pulled out of the housing, the lower layer unit descends under its own weight until the rollers supporting the lower layer unit contact the installation floor. Therefore, if the height gap between the rollers supporting the lower layer unit and the rollers supporting the housing is excessive, there is a risk of applying a load to the slide rails supporting the lower layer unit.

[0006] Therefore, a technical problem arises that must be solved in order to stably support the unit pulled out from the housing, and an object of the present invention is to solve this problem. [Means for solving the problem]

[0007] In order to achieve the above-mentioned objective, the currency handling device of the present invention comprises a housing to be installed on a floor surface, a unit having a currency handling section and capable of being inserted or pulled out from the housing, and a height adjustment mechanism that can collectively adjust the height of multiple casters supporting the unit relative to the floor surface. Effect of the Invention

[0008] In the present invention, when the unit is pulled out from the housing, the height adjustment mechanism lowers all of the casters that do not contact the floor surface when the unit is stored in the housing until they contact the floor surface, allowing the unit to be pulled out stably and approximately horizontally.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] A currency handling device according to an embodiment of the present invention will be described with reference to the drawings. Note that, hereinafter, when referring to the number, value, amount, range, etc. of components, unless otherwise specified or when it is clearly limited to a specific number in principle, the number is not limited to the specific number, and may be more or less than the specific number.

[0011] In addition, when referring to the shape or positional relationship of components, etc., this includes things that are substantially similar or approximate to those shapes, etc., unless otherwise specified or considered to be clearly different in principle.

[0012] In addition, the drawings may exaggerate characteristic parts to make the features easier to understand, and the dimensional ratios of the components may not be the same as the actual ones. In addition, in cross-sectional views, hatching of some components may be omitted to make the cross-sectional structure of the components easier to understand.

[0013] A currency handling device 1 according to one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the exterior of the currency handling device 1. FIG. 2 is a schematic diagram showing the internal structure of the currency handling device 1. FIG. 3 is a block diagram showing the configuration of the currency handling device 1. The currency handling device 1 is placed, for example, around a POS register and is used to deposit sales proceeds, dispense change, etc.

[0014] The currency processing device 1 has a housing 2 that is roughly rectangular in shape, and the right side of the page in Figure 1 is a coin processing device 10 that stores deposited coins and dispenses the stored coins as needed, and the left side of the page in Figure 1 is a banknote processing device 20 that stores deposited banknotes and dispenses the stored banknotes as needed.

[0015] The coin processing unit 10 has a coin deposit port 11, through which coins are inserted, provided on the front surface of the housing 2, and a coin withdrawal port 12, through which stored coins are withdrawn, provided below the coin deposit port 11. The coin withdrawal port 12 also serves as a coin reject port through which rejected coins are dispensed from the housing 2. Since the coin processing unit 10 has a known configuration, a detailed description of the coin processing unit 10 will be omitted.

[0016] The banknote processing unit 20 is provided with a banknote deposit / withdrawal port 21 on the front surface of the housing 2. The banknote deposit / withdrawal port 21 receives banknotes in a stacked state and dispenses banknotes stored in the banknote processing unit 20. The banknote deposit / withdrawal port 21 is provided with a detection sensor (not shown) that detects the presence or absence of banknotes.

[0017] In addition, the banknote processing unit 20 is provided, below the banknote deposit / withdrawal port 21, with a banknote deposit rejection port 22 through which banknotes that cannot be stored in the storage unit 50 described later (banknotes not eligible for storage) are fed out from within the housing 2 during deposit processing, and a banknote withdrawal rejection vault 23 which holds banknotes that cannot be withdrawn from the housing 2 so that they are not fed out during withdrawal processing.

[0018] As shown in FIG. 2, the currency handling device 1 includes a storage unit 50 capable of storing banknotes B, a banknote storage cassette 60, and a transport unit 70 that transports banknotes B within the housing 2.

[0019] The storage unit 50 includes three storage boxes 51 to 53 arranged in order from the front to the rear of the housing 2. The storage boxes 51 to 53 are single-denomination storage stackers that store different denominations of banknotes B. In this embodiment, the storage box 51 stores 1,000 yen notes, the storage box 52 stores 5,000 yen notes, and the storage box 53 stores 10,000 yen notes. The denominations of banknotes B stored in the storage boxes 51 to 53 can be changed as desired, and multiple denominations of banknotes B may be stored in the same stacker, or multiple stackers may store banknotes B of the same denomination. The number of storage boxes installed in the storage unit 50 is not limited to three, and may be two or less, or four or more.

[0020] The storage containers 51 to 53 have the same configuration. Each of the storage containers 51 to 53 has an opening at the top and is formed in a box shape, and can deliver banknotes B to and from the transport unit 70. The received banknotes B can be stored by being stacked in the vertical direction in a horizontal position with the longitudinal direction of the housing aligned with the left-right direction.

[0021] The banknote storage cassette 60 is provided below the banknote processing unit 20 in the housing 2. The banknote storage cassette 60 is configured to be able to store the banknotes B in the storage units 51 to 53. That is, for example, when it is found after a deposit process that the amount of stored banknotes B in any of the storage units 51 to 53 exceeds a predetermined amount, a certain amount of banknotes B can be collected from any of the storage units 51 to 53 as excess banknotes (overflow banknotes) in the banknote storage cassette 60 so as not to affect the subsequent deposit process. Alternatively, in the case of full collection in which all currency in the currency processing unit 1 is collected at the closing time of a store or the like in which the currency processing device 1 is installed, or in the case of residual collection in which the remaining currency is collected while leaving some currency for change the next day, the banknotes B in the storage units 51 to 53 to be collected can be collected in the banknote storage cassette 60. The banknote storage cassette 60 may be configured to be able to feed the banknotes stored therein toward the transport unit 70. That is, in the case of full recovery, since there is no currency in the currency processing device 1, it is necessary to load currency for change into the currency processing device 1 before the opening of the store or the like the next day. For this reason, the banknotes B for change can be fed from the banknote storage cassette 60 to the banknote processing unit 20 and distributed to the storage vaults 51 to 53. When the banknote storage cassette 60 is detachable from the housing 2, it is preferable that a closable shutter is provided at the opening of the banknote storage cassette 60, and the shutter automatically opens when the banknote storage cassette 60 is attached to the housing 2, and the shutter automatically closes when the banknote storage cassette 60 is removed from the housing 2. The number of banknote storage cassettes 60 installed can be changed as long as the number required for various processes can be secured.

[0022] The transport unit 70 includes a main transport path 71 connecting the banknote deposit / withdrawal slot 21 and the storage 53, and a feed roller (not shown) that separates banknotes B inserted into the banknote deposit / withdrawal slot 21 in a stacked state and feeds them one by one to the main transport path 71. The banknotes B are inserted into the banknote deposit / withdrawal slot 21 with their longitudinal direction aligned with the left-right direction of the housing, and are transported within the housing 2 while always maintaining this position even after being fed out to the transport unit 70.

[0023] The conveying section 70 also includes a first branch conveying path 72 that branches off from the main conveying path 71 near the storage facility 51 and is connected to the storage facility 51, and a second branch conveying path 73 that branches off from the main conveying path 71 near the storage facility 52 and is connected to the storage facility 52.

[0024] The transport section 70 also includes a third branch transport path 74 connected from the main transport path 71 to the banknote storage cassette 60, a fourth branch transport path 75 branching off from the third branch transport path 74 near the banknote deposit reject port 22 and connected to the banknote deposit reject port 22, and a fifth branch transport path 76 branching off from the third branch transport path 74 near the banknote withdrawal reject vault 23 and connected to the banknote withdrawal reject vault 23. The third branch transport path 74 extends so as to straddle a second processing unit 200 and a storage unit 300, which will be described later, and is made up of a processing side transport path 74a included in the second processing unit 200 and a storage side transport path 74b included in the storage unit 300.

[0025] The transport route along which the transport unit 70 transports the banknotes B can be arbitrarily switched by opening and closing gates (not shown) provided at the respective branching positions of the transport unit 70.

[0026] The conveying unit 70 is configured such that a conveying roller (not shown) is rotated by driving a conveying motor 77, and the conveying direction of the banknote B can be switched between a deposit direction D1 in which the banknote B is conveyed toward the storage unit 50 and a reverse direction D2 in which the banknote B is conveyed toward the banknote deposit / withdrawal port 21 or the banknote deposit reject port 22 according to the rotation direction of the conveying motor 77. The conveying motor 77 is, for example, a DC brushless motor, an AC motor, a stepping motor, or the like. The conveying speed of the conveying unit 70 may be substantially equal in the reverse direction D2 and in the deposit direction D1, but in order to prevent jamming, it is preferable that the conveying speed in the reverse direction D2 is set slower than the conveying speed in the deposit direction D1. In addition, when there is no risk of jamming and no recognition process of the banknote B is involved, the conveying speed of the conveying unit 70 may be set faster in the reverse direction D2 than in the deposit direction D1.

[0027] The banknote processing unit 20 includes a recognition unit 80 that recognizes banknotes B passing through the main transport path 71. Specifically, when a banknote B passes above the recognition unit 80, the recognition unit 80 recognizes and counts the denomination, authenticity, fitness (presence or absence of folds, cuts, tears, dirt, etc.) and transport abnormality (presence or absence of skewing at a predetermined angle or more, presence or absence of multiple feeds, etc.) of the banknote B. When the recognition unit 80 recognizes the banknote B as a genuine banknote, a proper banknote, and a normally transported banknote, the recognition unit 80 stores the banknote B in a storage unit 91 described later as a storage target banknote that is a banknote to be stored in the storage unit 50, and a banknote B that is not recognized as a storage target banknote by the recognition unit 80 and is recognized as unstorable is stored in the storage unit 91 as a non-storage target banknote.

[0028] For example, when the denomination of the recognized banknote B is any of the three pre-assigned denominations, the recognition unit 80 stores the banknote B in the memory unit 91 as a banknote to be stored. When the denomination of the recognized banknote B is any other denomination than the three pre-assigned denominations, the recognition unit 80 stores the banknote B in the memory unit 91 as a banknote not to be stored. Furthermore, when a specific generation of banknote is set as the banknote to be paid out by the banknote processing unit 20, the banknote of the specific generation is regarded as a banknote to be stored, and the banknote of the other generation (old note) is regarded as a banknote not to be stored. Furthermore, when the storage vaults 51 to 53 in which the denomination of the banknote B recognized by the recognition unit 80 is stored are full and cannot store the banknote B, the banknote B is stored in the memory unit 91 as a banknote not to be stored.

[0029] The recognition of the banknote B by the recognition unit 80 is not limited to being based on the entire banknote B, and may be performed by performing temporary recognition based on the characteristics of a part of the banknote B and then performing final recognition based on the characteristics of the other part of the banknote B. This allows the gate switching of the transport unit 70 to be performed early depending on the result of temporary recognition, and the size of the banknote processing unit 20 can be made compact. If the result of temporary recognition differs from the result of final recognition, the gate switching is performed depending on the result of temporary recognition, and then the transport direction of the transport unit 70 is switched to the reverse direction D2 depending on the result of final recognition to transport the banknote B to the banknote deposit reject port 22. The part of the banknote B that is the basis of temporary recognition may be set to 1 / 2, 1 / 3, or 2 / 3, etc., in terms of area ratio to the entire banknote B. The recognition unit 80 is not limited to being a unit that performs recognition in two stages, temporary recognition and final recognition, and may be a unit that performs recognition only once.

[0030] The operation of the banknote processing unit 20 is controlled by the control unit 90. The control unit 90 controls each of the components constituting the banknote processing unit 20. The control unit 90 is composed of, for example, a CPU, a memory, and the like. The memory of the control unit 90 includes a storage unit 91 in which at least the quantity of banknotes B stored in the storage vaults 51 to 53 is appropriately updated and recorded. The housing 2 is also provided with a display unit 30 such as a liquid crystal screen used for operating the currency processing device 1, and an input unit 40 through which operation input is made. The housing 2 is also provided with a management unit 3 that controls the operation of the currency processing device 1 in response to an instruction from the outside or an input operation via the input unit 40. Instead of a configuration in which the management unit 3 controls the entire currency processing device 1 and the control unit 90 controls the banknote processing unit 20, for example, a configuration in which the entire currency processing device 1 is controlled by one control unit may be used.

[0031] As shown in Figures 4 and 5, the currency handling device 1 includes a first processing unit 100, a second processing unit 200, and a storage unit 300. The first processing unit 100, the second processing unit 200, and the storage unit 300 are configured to be independently inserted or pulled out from the housing 2 via slide rails (not shown) or the like. Hereinafter, the direction in which each of the units 100, 200, 300 is inserted into the housing 2 is referred to as the "insertion direction D3," and the direction in which each of the units 100, 200, 300 is pulled out from the housing 2 is referred to as the "pulling out direction D4."

[0032] The first processing unit 100 is disposed on the upper right side of the housing 2, and the coin processing unit 10 is provided therein. When the first processing unit 100 is pulled out from the housing 2 during maintenance or the like of the coin processing unit 10, the operator of the currency processing device 1 can access the inside of the coin processing unit 10.

[0033] The second processing unit 200 is disposed on the upper left side of the housing 2, and includes therein the banknote processing unit 20, the storage unit 50, and part of the transport unit 70. When the second processing unit 200 is pulled out from the housing 2 during maintenance or the like of the banknote processing unit 20, the operator of the currency processing device 1 can access the inside of the banknote processing unit 20, such as the main transport path 71 and the recognition unit 80.

[0034] The storage unit 300 is disposed below the first processing unit 100 and the second processing unit 200 with a small gap therebetween, and is provided therein with a banknote storage cassette 60 and part of the transport unit 70 as a currency handling unit, a coin storage cassette 301 capable of storing coins transported from the coin processing unit 10, and a coin bar drawer 302 for storing coin bars. When the storage unit 300 is pulled out of the housing 2 to replace the banknote storage cassette 60 or the like, the operator of the currency processing device 1 can access the banknote storage cassette 60. It should be noted that the currency handling unit provided in the storage unit 300 is not limited to the banknote storage cassette 60, the coin storage cassette 301, the coin bar drawer 302, etc. described above.

[0035] As shown in FIG. 6, the storage unit 300 includes a drawer frame 310 and a cassette frame 320.

[0036] Casters 330 are provided at the bottom of the drawer frame 310 to support the drawer frame 310 on the front side in the drawer direction D4. When the drawer frame 310 is inserted into or drawn out from the housing 2, the casters 330 roll smoothly, allowing the drawer frame 310 to move smoothly. The casters 330 are provided on the front wall 311 of the drawer frame 310 via a height adjustment mechanism 340. The specific configuration of the height adjustment mechanism 340 will be described later. Note that reference numeral 2a in FIG. 6 denotes casters provided at the bottom of the four corners of the housing 2, which support the housing 2 movably on the floor surface F.

[0037] The cassette frame 320 is detachably stored in the frame pocket 312 of the drawer frame 310 from above. Comb-tooth-shaped supported portions 322 are formed on the upper portions of the left and right side surfaces 321 of the cassette frame 320. As shown in Fig. 7, the supported portions 322 are engaged with comb-tooth-shaped support portions 313 formed near the opening of the frame pocket 312 with a slight gap g in the drawer direction D4, thereby allowing the cassette frame 320 to move slightly in the drawer direction D4. The cassette frame 320 is also configured to detachably store the banknote storage cassette 60 in the cassette pocket 323 from above.

[0038] Furthermore, horizontal support shafts 324 are respectively provided protruding from the lower portions of the left and right side surfaces 321 of the cassette frame 320, which engage with shaft supports 314 formed in a recessed shape in the drawer frame 310 when the cassette frame 320 is stored in the frame pocket 312. When the cassette frame 320 is stored in the frame pocket 312, as shown in Figures 7 and 8, the cassette frame 320 can swing around the horizontal support shaft 324 by, for example, approximately ±1 degree, that is, between approximately 1 degree toward the rear in the insertion direction D3 and approximately 1 degree toward the front in the drawer direction D4.

[0039] Furthermore, the horizontal support shaft 324 of the cassette frame 320 is provided offset toward the front side in the pull-out direction D4 from the center of gravity G of the cassette frame 320 that stores the banknote storage cassette 60, when viewed from the left-right direction of the housing 2. In other words, when the banknote storage cassette 60 is stored in the cassette frame 320, the center of gravity of the banknote storage cassette 60 and the cassette frame 320 is located on the rear side in the insertion direction D3 from the horizontal support shaft 324. As a result, as shown in Fig. 7, the cassette frame 320 in a state pulled out from the housing 2 is inclined due to its own weight toward the rear side in the insertion direction D3, when viewed from the left-right direction of the housing 2.

[0040] On the other hand, as shown in Figure 9, when the storage unit 300 is inserted into the housing 2 with the banknote storage cassette 60 tilted toward the rear in the insertion direction D3, and as shown in Figure 10, when the rear shoulder 61 of the banknote storage cassette 60 abuts against the positioning portion 201 protruding from the bottom surface of the second processing unit 200, the banknote storage cassette 60 swings toward the front in the withdrawal direction D4 around the horizontal support axis 324.

[0041] That is, in a non-contact state where the banknote storage cassette 60 is not in contact with the positioning portion 201 of the second processing unit 200, the banknote storage cassette 60 is supported by the storage unit 300 in a posture tilted toward the rear side in the insertion direction D3. On the other hand, in a contact state where the banknote storage cassette 60 is in contact with the positioning portion 201 of the second processing unit 200, the banknote storage cassette 60 is supported by the storage unit 300 in a substantially vertical posture.

[0042] At this time, the opening 74c of the third branched transport path 74 (processing side transport path 74a) in the second processing unit 200 and the opening 74d of the third branched transport path 74 (storage side transport path 74b) in the storage unit 300 are provided at positions where the distances from the positioning part 201 and the shoulder part 61 are approximately the same when the shoulder part 61 is in contact with the positioning part 201. Therefore, the banknote storage cassette 60 is positioned with respect to the second processing unit 200 so that the storage side transport path 74b is connected to the processing side transport path 74a in an approximately straight line. Note that "connected in an approximately straight line" is not limited to the case where the processing side transport path 74a and the storage side transport path 74b are connected in a straight line, but also includes the case where one is connected at an angle to the other within a range where banknotes B can be transferred. In this way, the inclination of the storage side conveying path 74b relative to the processing side conveying path 74a is allowed within a specified range in which banknotes B can be transferred, so that the positioning of the storage side conveying path 74b relative to the processing side conveying path 74a can be performed accurately and flexibly without complicated assembly work.

[0043] Furthermore, by the multiple transport guides 202 arranged in a comb-tooth shape near the opening 74c of the processing side transport path 74a and the multiple transport guides 62 arranged in a comb-tooth shape near the opening 74d of the storage side transport path 74b engaging with each other, banknotes B are transferred smoothly without getting stuck near the boundary between the second processing unit 200 and the storage unit 300.

[0044] Incidentally, by providing a biasing means (not shown) for biasing the cassette frame 320 backward in the insertion direction D3, the cassette frame 320 can be prevented from inadvertently swinging forward in the withdrawal direction D4.

[0045] Furthermore, the cassette frame 320 is not limited to being supported by the drawer frame 310 so as to be swingable around the horizontal support axis 324, but may be configured, for example, so that the cassette frame 320 is supported by the drawer frame 310 so as to be freely movable in the insertion direction D3, and is biased toward the rear side in the insertion direction D3 by a biasing means (not shown), and is positioned relative to the second processing unit 200 so that when the shoulder portion 61 abuts against the positioning portion 201, the banknote storage cassette 60 moves to the front side in the drawer direction D4, and then the storage side conveying path 74b is connected in an approximately straight line to the processing side conveying path 74a.

[0046] Furthermore, the banknote storage cassette 60 is not limited to being indirectly stored in the drawer frame 310 via the cassette frame 320, but may be directly stored in the drawer frame 310 without the cassette frame 320, provided that it is capable of moving slightly in the drawer direction D4 relative to the drawer frame 310.

[0047] Next, the height adjustment mechanism 340 for adjusting the height of the casters 330 of the drawer frame 310 will be described with reference to Figures 11 and 12. The height adjustment mechanism 340 comprises a caster module 350 on which the casters 330 are mounted, and a guide module 360 ​​provided on the back surface 315 of the front wall 311 of the drawer frame 310.

[0048] The caster module 350 includes a support plate 351 having two casters 330 arranged side by side at a distance from each other in the left-right direction (horizontal direction) at the lower end thereof, and a link plate 352 connected to the support plate 351.

[0049] Two casters 330 are provided on the support plate 351 at a distance in the left-right direction. Guided surfaces 353 are formed on the left and right sides of the support plate 351, respectively, and are inclined with respect to the left-right direction and the height direction.

[0050] The link plate 352 is provided approximately in the center of the support plate 351. A slit 355 is formed approximately parallel to the guided surface 353 at each end of the link plate 352, and a bolt 354 is inserted through the slit 355. The caster module 350 is positioned by fastening the link plate 352 to the front wall 311, and the multiple caster modules 350 can move collectively relative to the front wall 311 by loosening the bolt 354 fastened to the front wall 311.

[0051] Guide module 360 ​​is fixed to front wall 311 so as to be located above caster module 350. Guide surfaces 361 that come into sliding contact with guided surfaces 353 are formed on the left and right sides of guide module 360. Furthermore, a receiving portion 362 that receives link plate 352 is formed approximately in the center of guide module 360.

[0052] As a result, when the caster module 350 moves relative to the front wall 311, the guided surface 353 comes into sliding contact with the guide surface 361, and the moving direction of the caster module 350 is regulated, so that the height of the caster 330 can be adjusted steplessly and stably, as shown in Figures 11 and 12. Then, after the caster 330 reaches a desired height position, the bolt 354 is tightened to fasten the link plate 352 to the front wall 311, thereby fixing the position of the caster 330.

[0053] 11, by continuously adjusting the amount of descent of the casters 330 in accordance with the unevenness of the floor surface F, the casters 330 are lowered until they come into contact with the floor surface F, so that the drawer frame 310 can be stably drawn out substantially horizontally. Furthermore, the caster module 350 supports the weight of the drawer frame 310 over the entire guided surface 353, so that the drawer frame 310 can be stably supported.

[0054] 12, when the drawer frame 310 is stored in the housing 2, the casters 330 are raised and positioned at a position where they are raised by a few millimeters above the floor surface F. As a result, the casters 330 of the drawer frame 310 do not contact the floor surface, and so when the currency handling device 1 is moved, only the casters 2a of the housing 2 roll on the floor surface F, allowing the currency handling device 1 to be moved smoothly.

[0055] The shape of the guided surface 353 is not limited to a smooth inclined surface as shown in Figures 11 and 12, and may be formed in a step shape in the left-right and height directions as shown in Figures 13 and 14. When the guided surface 353 is formed in a step shape including a horizontal portion and a vertical portion, when the drawer frame 310 is drawn out from the housing 2 and the casters 330 are lowered as shown in Figure 13 to be supported by the casters 330, the caster module 350 supports the weight of the drawer frame 310 on the horizontal portion of the guided surface 353. Therefore, slippage is suppressed and the drawer frame 310 can be supported more stably than when the drawer frame 310 is supported by the inclined guided surface 353 as shown in Figures 13 and 14.

[0056] In this manner, the currency handling device 1 of this embodiment is configured to include a housing 2 that is placed on a floor surface F, a storage unit 300 that has a banknote storage cassette 60 and can be inserted or removed from the housing 2, and a height adjustment mechanism 340 that can collectively adjust the height of multiple casters 330 that support the storage unit 300 relative to the floor surface F.

[0057] According to this configuration, when the storage unit 300 is pulled out from the housing 2, the height adjustment mechanism 340 lowers all of the casters 330, which do not contact the floor surface F when the storage unit 300 is stored in the housing 2, until they contact the floor surface F, so that the storage unit 300 can be pulled out stably and approximately horizontally.

[0058] Furthermore, the present invention can be modified in various ways other than those described above without departing from the spirit of the present invention, and it goes without saying that the present invention extends to such modifications. [Explanation of symbols]
