Field of the Invention The present invention relates to an attachment / detachment device for attaching / detaching a slide loading type box such as a cartridge, a cassette, or a tray to / from an apparatus main body, and in particular, an attachment / detachment device for a slide loading type box that facilitates loading of the box It is about.

  Office machines such as copiers and printers often contain consumables such as paper in cartridges or cassettes, and these boxes are of a slide loading type. For example, in a printer, a paper cassette or a paper tray is a slide loading type, and a paper cassette or the like is generally pulled out from a cassette housing chamber of the main body to replenish paper (Patent Document 1).

Also, in a bind processing machine that automatically attaches a ring-type binder to paper with punch holes formed therein, the ring-type binder is accommodated in a slide-loading type binder cartridge, and the binder cartridge is removed from the cartridge storage chamber of the bind processing machine. The binder is pulled out to replenish the binder to the binder cartridge (Patent Document 2).
Japanese Patent Laid-Open No. 2004-77788 (FIG. 1, paragraph number 0024) JP 2005-059396 A

  Slide-loading boxes such as printer paper cassettes and binder cartridges for bind processing devices are larger and heavier than data media cartridges, staple cartridges, etc. The insertion operation requires attention. However, this type of equipment used for paperwork is not always handled by those who are familiar with the operation, and in many cases it is handled by an unspecified number of people at the actual site. In addition, stress may be applied to the cartridge and the cartridge may be deformed or damaged.

  The present invention is proposed in order to solve the above-described problem, and facilitates the attaching / detaching operation by preventing unnecessary stress from being applied to the slide-loading box and the box-loading chamber when the slide-loading box is attached / detached. And it aims at enabling it to position a box accurately.

  The present invention proposes to achieve the above object, and is a slide loading type in which a slide loading type box such as a cartridge, a cassette, or a tray can be attached to and detached from the box housing unit and can be locked at a loading position. In the box attachment / detachment device, guide bosses are provided at the front and rear portions in the insertion direction of the slide loadable box, and the front and rear guide bosses are engaged with the box housing portion to guide the insertion of the slide loadable box. The guide groove is provided so that the diameter of the rear guide boss is substantially equal to the groove width of the guide groove, the diameter of the front guide boss is made smaller than the groove width of the guide groove, and a cam is mounted on the back end side of the guide groove. The cam is engaged with and locked to the front guide boss of the loaded slide-loading box, and the front guide is pulled out when the slide-loading box is pulled out. Boss The overcoming is to provide a detachable device for forming slides-loading box body as the lock is released.

  Also, a slide loading type box provided with a pressing plate that contacts the upper surfaces of the front and rear guide bosses when the loading of the slide loading type box is completed and eliminates the gap between the slide loading type box and the guide groove. A body attachment / detachment device is provided.

  When inserting the slide loadable box by engaging the guide boss provided at the front of the side of the slide loadable box such as a cartridge, cassette, or tray with the guide groove provided in the box load chamber Since the diameter of the front guide boss is smaller than the width of the guide groove, there is room for the guide groove and the front guide boss, making it easy to insert and not applying excessive force to the guide groove or guide boss. . Further, immediately before the insertion is completed, the rear guide boss of the slide-loading box is engaged with the guide groove, and a spring cam such as a lever type is engaged with the front guide boss and locked. Since the diameter of the rear guide boss is close to the groove width of the guide groove, the rear portion of the slide-loadable box has almost no backlash, and the front guide boss does not rattle due to the cam being elastically contacted. Therefore, there is almost no possibility of damaging the slide loading type box and the guide groove when the box is attached / detached, and the attachment / detachment is easy and the positioning accuracy is good.

  Further, in the state where the box loading is completed, if a pressing plate that contacts the upper surfaces of the front and rear guide bosses is provided, the backlash of the slide loading box is further reduced, and the positioning accuracy is improved.

  The present invention relates to an apparatus for loading and using a slide-loadable box in a box-loading chamber. Guide bosses are provided at the front and rear in the insertion direction on the side surface of the slide-loadable box, and front and rear of the box-loading chamber. A guide groove that engages with the guide boss of the slide guide and guides the insertion of the slide loadable box is provided, the diameter of the rear guide boss is made substantially equal to the groove width of the guide groove, and the diameter of the front guide boss is made the groove of the guide groove. The cam has a smaller diameter than the width, a cam is arranged on the far end side of the guide groove, a spring is inserted into the cam and protrudes onto the guide groove, and the cam is mounted on the front guide boss of the loaded slide-loading box. Engagement locks the front guide boss over the cam when the box is withdrawn so that the lock is released, facilitating box attachment and detachment operations and positioning the slide-loadable box with high precision Achieved the goal of

  FIG. 1 and FIG. 2 show a binder cartridge 1 used in a binding processing apparatus as an example of a slide loading type box, and a slide cover 3 is slidably assembled to a tray 2, and as shown in FIG. The tray 2 can be exposed by sliding 3 backward.

  A pusher 4 for pushing the binder 101 forward is disposed on the tray 2, and the tip of the spiral spring 5 is fixed to the front of the inner surface of the slide cover 3 with screws or pins, as shown in FIG. Further, the coil portion of the spiral spring 5 is locked to the spring holder portion 6 provided on the pusher 4. As a result, when the slide cover 3 is slid rearward, the spiral spring 5 is rewound and the pusher 4 moves backward together with the slide cover 3. When the binder 101 is loaded on the tray 2 and the slide cover 3 is slid forward and closed, the pusher 4 that has advanced with the slide cover 3 comes into contact with the back of the binder in the last row and stops, and the spiral spring 5 is stretched. . The pusher 4 is given a forward force to the spiral spring 5 to push the binder 101 forward, and the pusher 4 and the binder 101 move forward as the binder 101 is consumed.

  FIG. 4 shows the pusher 4, in which a plurality of ring support portions 4 b are arranged at intervals on both upper and lower surfaces of a thin plate 4 a portion covering almost the entire width of the tray 2. A binder 101 in which a large number of ring parts 102 are connected by a spine part 103 has a structure in which the ring is divided into three parts, and as shown in FIG. 5, the ring support part 4b supports the upper and lower ends of the ring part 102 from the back, The arcuate convex portion 4c similar to the inner peripheral surface shape of the 1/3 ring portion supports the binder 101 so as not to be displaced up and down, so that the binder 101 is not tilted back and forth or displaced up and down.

  2 and 3, the tray 2 is provided with three rows of groove-shaped guide rails 7 (hereinafter simply referred to as guide rails 7), and the slide cover 3 is also symmetrical with the guide rails 7 of the tray 2. Three rows of groove-shaped guide rails 8 (hereinafter simply referred to as guide rails 8) are provided. Guide grooves 7a and 8a are formed at the center of the guide rails 7 and 8, and the lower 1/3 ring portion of the binder 101 enters the guide groove 7a groove of the guide rail 7 of the tray 2, and the upper side 1 of the binder 101. The / 3 ring part enters the guide groove 8a of the guide rail 8 of the slide cover 3, and the binder 101 moves straight along the guide grooves 7a and 8a.

  FIG. 6 shows the guide rail 7 at the center of the tray 2 and the guide rail 8 of the slide cover 3. The entire ring portion 102 of the binder 101 enters the guide grooves 7a and 8a of the guide rails 7 and 8 and is positioned in the left-right direction. Is made. In addition, the gap between the guide rail 7 and the guide rail 8 serves as a vertical positioning guide groove, and the spine 103 of the binder 101 is sandwiched between the guide rail 7 and the guide rail 8 to perform vertical positioning.

  FIG. 7 is a front view of the binder cartridge 1, where (a) shows a state in which a large-diameter binder 101 for 100 sheets of A4 paper is loaded, (b) shows a small-diameter binder 111 for 50 sheets of A4 paper, (c) Indicates the state of loading a large-diameter binder 121 for 100 sheets of letter-size paper, and (d) shows a state in which a small-diameter binder 131 for 50 sheets of letter-size paper is loaded, respectively. Positions near both ends.

  FIG. 8 (a) shows a state where the ring portion 102 of the binder 101 is engaged with the guide groove 7a of the guide rail 7 of the tray 2, and FIG. 8 (b) shows the gap between the upper and lower guide rails 7, 8. The state where the spine 103 of the binder 101 is supported by the guide groove is shown.

  As shown in FIG. 9 (a), the width of the guide groove 7a of the guide rail 7 is wider than the ring portion 102 of the binder 101 from the rear end to the vicinity of the front end of the front side, and the width of only the front end is the binder 101. The ring portion 102 is substantially equal to the width of the ring portion 102, and is formed so as to gradually shift from the wide portion to the narrow portion.

  Further, as shown in FIG. 9 (b), the lower end surface of the guide rail 8 of the slide cover 3 is different in height from the rear end to the vicinity of the front end on the front side, and through a gentle slope. A step is provided, and the groove width, which is the gap between the upper and lower guide rails 7 and 8 at the tip, is substantially equal to the vertical width of the spine 103 of the binder 101, and the other portions are wider. In the figure, the change of the groove width is exaggerated from the actual one.

  In this way, the groove width of the guide rails 7 and 8 and the vertical distance of the guide rails 7 and 8 are almost equal to the dimensions of the binder only at the tip, and the other parts have a margin with respect to the dimensions of the binder. Therefore, there is little frictional resistance when a large number of binders stacked in the front-rear direction move forward, and the movement is performed smoothly. Further, when loading the binder into the tray 2, the ring portion of the binder can be easily inserted into the guide groove 7a of the guide rail 7, so that the workability is good.

  Next, the binder remaining amount detection mechanism will be described. As shown in FIG. 3, on the guide rail 7 at the center of the tray 2, four remaining number detection levers 9 projecting upward from the inside of the guide rail 7 are arranged at intervals in the front-rear direction. When a specified amount of binder 101 is loaded in the tray 2, the spine 103 of the binder 101 on the guide rail 7 presses the tip of the remaining number detecting lever 9 downward, and the remaining number detecting lever 9 is placed in the guide rail 7. Die.

  As shown in FIG. 10, the other end portion of the L-shaped remaining number detecting lever 9 is engaged with one end of a link lever 10 that is disposed on the bottom surface of the tray 2 and is rotatable in the horizontal direction. The tip of the remaining number detection lever 9 is projected onto the guide rail 7 by a tension coil spring 11 interposed therebetween.

  A reflection type photosensor 51 facing the lower surface side of the end of the link lever 10 is disposed in a cartridge housing chamber of a bind processing device (not shown) in which the binder cartridge 1 is loaded, and the remaining number detection lever. In the state where the tip of 9 protrudes on the guide rail 7 (the state shown in FIG. 10 (b)), the end of the link lever 10 is at a position off the top of the reflective photosensor 51, and the reflective photosensor 51 The output is off.

  When the binder 101 is loaded into the binder cartridge 1, the remaining number detection lever 9 is pushed by the spine 103 of the binder 101 and sunk in the guide rail 7, and the remaining number detection lever 9 resists the force of the tension coil spring 11. Then, the link lever 10 is rotated, and the end of the link lever 10 is positioned immediately above the reflective photosensor 51 as shown in FIG. 10 (a), and the output of the reflective photosensor 51 is turned on.

  The binding processing device operates to perform the binding process, and as the binder 101 is consumed, the binder 101 and the pusher 4 move forward, and the pusher 4 further moves forward from the position immediately above the remaining number detection lever 9 shown in FIG. As shown in FIG. 10 (b), when the position of the remaining number detecting lever 9 is passed, the remaining number detecting lever 9 whose pressure is released rises to the initial position and the link lever 10 also returns to the initial position. The end of the lever 10 moves directly above the reflective photosensor 51, and the reflective photosensor 51 is turned on.

  In this way, the position of the pusher 4 can be detected by the four remaining number detection levers 9 disposed on the guide rail 7 and the four reflection type photosensors 51 corresponding thereto, and the control unit of the bind processing device has four control units. The remaining number of binders (for example, 30, 20, 10, 0, etc.) is determined according to the on / off state of the reflective photosensor 51. The control unit of the binding processing device divides the number of binding processing executions from the time when the remaining number is detected as well as the remaining number detected from the ON signal of the reflection type photosensor 51 of the remaining amount detection mechanism, by one unit. The remaining number can be detected, and this remaining number is sequentially displayed on the display unit. When the remaining number reaches a certain number, a warning is displayed, and when the remaining number becomes 0, the start of the bind processing device is prohibited. Can be configured.

  Next, the binder loading direction detection mechanism will be described. The binder must be loaded in the normal direction shown in Fig. 3, etc.If the front and back are loaded in reverse, not only the paper cannot be bound, but also the binder may be damaged and the binding mechanism may jam. When a binder cartridge loaded with a binder in the reverse direction is installed, a means for prohibiting the start of the bind processing device is required.

  11 (a) and 11 (b) show the loading direction detection lever 12, which is arranged in the binder cartridge 1 like the remaining number detection lever 9, and can be rotated in the horizontal direction around the vertical shaft portion 12a as the rotation center. 12b is at the side surface position of the ring portions 102, 112 of the binders 101, 111 in the foremost row, and the rear end 12c extends horizontally on the bottom side of the tray 2.

  Fig. 11 (a) shows a case where 50 small-diameter binders 111 are loaded in the normal direction, and Fig. 11 (b) shows a case where 100 large-diameter binders 101 are loaded in the normal direction. In any case, the leading end 12b of the loading direction detection lever 12 is slightly in front of the binders 103 and 113 just below the spine portions 103 and 113 (in the drawing, in the depth direction of the drawing), and the rings of the binders 101 and 111 Since the portions 102 and 112 are curved backward (frontward in the drawing) from the position of the spine portion, the tip 12b of the loading direction detection lever 12 is not in contact with the ring portions 102 and 112. Therefore, the loading direction detection lever 12 maintains the initial state, the rear end 12c is directly above the reflection type photosensor 61 on the binding processing device side, and the light emitted from the light emitting part of the reflection type photosensor 61 detects the loading direction. The light is reflected from the bottom surface of the rear end 12c of the lever 12 and returned to the light receiving unit, and the output state of the reflective photosensor 61 is on.

  FIG. 12 (a) shows a case where 50 small-diameter binders 111 are loaded in the reverse direction, and FIG. 12 (b) shows a case where 100 large-diameter binders 101 are loaded in the reverse direction. In any case, since the direction of the binder is reversed, the front end 12b of the loading direction detection lever 12 contacts the side surfaces of the ring portions 102 and 112 of the binders 101 and 111 and rotates from the initial position, and the rear end 12c The output state of the reflective photosensor 61 is off because the optical path of the reflective photosensor 61 has deviated.

  FIG. 13 shows the front surface of the binder cartridge 1 loaded with 50 small-diameter binders 111. In (a), the binder 111 is in the normal orientation, and (b) shows the binder 111 in the reverse orientation. . (a) shows a state in which the tip 12b of the loading direction detection lever 12 protrudes into the binder passage. In (b), the tip 12b of the loading direction detection lever 12 is pushed by the ring portion 112 to guide rail. Retracted into 7.

  FIG. 14 shows the front surface of the binder cartridge 1 loaded with 100 large-diameter binders 101, where (a) shows the binder 101 in the normal orientation, and (b) shows the binder 101 in the reverse orientation. 13, the tip 12b of the loading direction detection lever 12 protrudes into the binder passage in (a), and the tip 12b of the loading direction detection lever 12 is pushed by the ring portion 102 in the guide rail 7 in (b). Retracted.

  The controller of the binding processing device determines that the binder loading direction is normal when the output of the reflective photosensor 61 of the loading direction detection mechanism is on, and determines that the binder loading direction is reversed when the output is off. By configuring so as to prohibit the starting, it is possible to prevent an accident due to an error in the binder loading direction.

  In addition, the remaining amount detection lever 9 of the remaining amount detection mechanism or a lever for detecting the ring portion is added to the positions of the ring portions at both the left and right ends or one end of the A4 paper binders 101 and 111 shown in FIGS. 7 (a) and 7 (b). Then, the combination of the detection values with the other remaining amount detection lever 9 described above detects 23 ring A4 binders 101 and 111 or 21 ring letter size binders 121 and 131 shorter than A4. be able to.

  Next, the binder ring size detection mechanism will be described. FIGS. 15 (a) and 15 (b) show the ring size detection lever 13, and like the loading direction detection lever 12, can rotate in the horizontal direction around the vertical shaft portion 13a, as shown in FIG. 15 (b). The front end 13b is directly below the ring portion 112 of the frontmost row of small-diameter binders 111, and the rear end 13c extends horizontally on the bottom side of the tray 2. In the initial state, the rear end 13c of the ring size detection lever 13 is directly above the reflection type photosensor 71, and the output state of the reflection type photosensor 71 is on, and as shown in FIG. Even when loaded, the tip 13b of the ring size detection lever 13 does not contact the side surface of the ring portion 112 of the small-diameter binder 111, and the output state of the reflective photosensor 71 remains on.

  On the other hand, as shown in FIG. 15 (a), when the large-diameter binder 101 is loaded, since the vertical dimension of the ring portion 102 is longer than the vertical dimension of the small-diameter binder 111, the tip 13b of the ring size detection lever 13 is The ring size detection lever 13 is rotated on the side surface of the part 102, the rear end 13c thereof is out of the optical path of the reflection type photosensor 71, and the output state of the reflection type photosensor 71 is turned off.

  16 (a) shows the front surface of the binder cartridge 1 loaded with 100 large-diameter binders 101, and FIG. 16 (b) shows the front surface of the binder cartridge 1 loaded with 50 small-diameter binders 111. . (a) shows that the tip 13b of the ring size detection lever 13 is pushed by the ring portion 102 of the large-diameter binder 101 and retracted into the guide rail 7, and (b) shows the ring size detection lever. A state in which the tip 13b of 13 protrudes into the binder passage is shown.

  The control unit of the bind processing device can determine the ring size of the binder in the binder cartridge 1 based on the output state of the reflective photosensor 71 of the ring size detection mechanism, and can display the type of binder on the display unit. . In the case of a system in which the bind processing device is linked with a copying machine, the number of sheets information from the copying machine and the ring size information from the ring size detection mechanism are collated, and the number of sheets to be bound and the ring size of the binder are determined. In the case of non-conformity, it is possible to configure to execute a process of displaying a warning after stopping the binding process.

  As described above, the bind processing device detects the remaining amount and presence of the binder, the loading direction of the binder, the ring size of the binder, the length of the binder, etc. by using the various levers 9, 12, and 13 provided in the binder cartridge 1. However, the presence or absence of the binder cartridge 1 can also be detected from the signals of the remaining amount detection photosensor 51 and the loading direction detection photosensor 61.

  In other words, when the binder cartridge 1 is not loaded in the bind processing device, both the remaining amount detection photosensor 51 and the loading direction detection photosensor 61 on the bind processing device side output because the levers 10 and 12 do not exist on the optical path. Is off. Further, when the binder cartridge 1 that has not been loaded with the binder is loaded into the binding processing apparatus, or when the binder of the binder cartridge 1 is used up, the output of the remaining amount detection photosensor 51 is off, and the loading direction detection lever 12 is Since it is in the initial position shown in FIG. 11, the output of the loading direction detection photosensor 61 is turned on. When the binder cartridge 1 has a binder and the loading direction of the binder is correct, both the remaining amount detection photosensor 51 and the loading direction detection photosensor 61 are turned on. When the loading direction of the binder is reversed, the remaining amount is detected. The quantity detection photosensor 51 is turned on and the loading direction detection photosensor 61 is turned off.

  Contrary to the configuration shown in FIG. 11, when the output of the loading direction detection photosensor 61 is turned off when the loading direction detection lever 12 is in the initial position, the binder cartridge 1 is loaded in the binding processing device. In addition to the case where the binder cartridge 1 is used up, the output of both the remaining amount detection photo sensor 51 and the loading direction detection photo sensor 61 is turned off, so the binder cartridge is used up when the binder cartridge is not installed. In this case, the combination of sensor signals is the same, and the presence or absence of the binder cartridge 1 cannot be determined.

  On the other hand, as shown in FIG. 11, in the configuration in which the output of the loading direction detection photosensor 61 is turned on when the loading direction detection lever 12 is in the initial position, the remaining amount detection photosensor 51 and Both the loading direction detection photosensors 61 are not turned off, and the presence or absence of the binder cartridge 1 can be determined without providing a sensor or switch for detecting the presence or absence of the binder cartridge 1 separately.

  FIG. 17 (a) shows the frame 81 of the bind processing device, and the binder cartridge 1 is inserted into the rectangular opening 82 on the side from the side. Horizontal guide rails 83 are provided in parallel on the left and right inner wall surfaces of the frame 81. When the binder cartridge 1 is fully inserted as shown in FIG. 17 (b), the binder cartridge 1 is fixed by a lock mechanism described later. Is done.

  FIG. 18 shows the binder cartridge 1, and the frame 81 of the bind processing apparatus is loaded with the front opening shown in FIGS. 1 and 2 facing downward as shown. A side cover 14 is attached to the right side surface of the slide cover 3, and a handle 15 is attached to the side cover 14. Two guide bosses 17 and 18 are provided on the top surface (left side surface in the figure) of the front cover 16 (lower side in the figure) on the front and rear sides. The guide boss 17 has a small diameter.

  In addition, as shown in the figure, the side cover 14 is provided with a display board mounting portion 19, and a plate indicating the type of binder (A4 / 100 sheets, LTR / 50 sheets, etc.) is attached to or attached to the display board mounting section 19. In this case, a binder cartridge containing an appropriate binder can be definitely selected. Further, if the slide cover 2 and the side cover 14 are formed of a transparent plastic so as to be a so-called skeleton type, the type and remaining amount of the binder can be visually observed. In addition, if a transparent window or opening is provided in the bind processing device so that the display plate mounting portion 19 of the loaded binder cartridge 1 can be seen, it is convenient that the binder type can be confirmed without removing the binder cartridge. .

  FIG. 19 shows the cartridge holder frame 84 of the bind processing apparatus, and the binder cartridge 1 is loaded from the opening 82 on the right side. A horizontal guide groove 87 is formed in the vicinity of the lower end of the left side surface 85 (front side in FIG. 19) of the cartridge holder frame 84 from the opening 82 to the vicinity of the rear surface 86, and the guide boss 17 provided on the side surface of the binder cartridge 1. Is engaged with the guide groove 87 and pushed into the interior of the cartridge holder frame 84.

  FIG. 20 (a) shows the guide groove 87 of the cartridge holder frame 84. FIG. The vertical width of the guide groove 87 is wider than the diameter of the small-diameter guide boss 17 of the binder cartridge 1, so that the binder cartridge 1 can be inserted smoothly and easily. Press plates 88 and 89 projecting in the lateral direction are cut and raised at the back of the guide groove 87 and the upper edge near the entrance. The ends of the holding plates 88 and 89 in the direction of the opening 82 are inclined upward so that the guide bosses 17 and 18 of the binder cartridge 1 are smoothly guided to the lower surfaces of the holding plates 88 and 89. As shown in FIG. 20 (b), at a position where the binder cartridge 1 is completely loaded, the holding plates 88 and 89 hold the guide bosses 17 and 18 of the binder cartridge 1 from above so that there is no backlash. The cartridge 1 is held.

  As shown in FIG. 19, a cam lever 90 is attached near the back end of the guide groove 87 of the cartridge holder frame 84. As shown in FIG. 21, the rear end of the cam lever 90 formed with an upward angle cam portion 90a in the intermediate portion is engaged with a shaft 91 provided on the side surface of the cartridge holder frame 84, and the front end portion of the cam lever 90 The cam lever 90 is urged upward by a tension coil spring 92 interposed on the side surface of the cartridge holder frame 84.

  The cam lever 90 engages and locks the small-diameter guide boss 17 of the binder cartridge 1. When the binder cartridge 1 is inserted into the cartridge holder frame 84, the small-diameter guide boss 17 that has advanced along the guide groove 87 becomes the guide groove. Immediately before the end of 87, the cam lever 90 comes into contact with the angle cam portion 90a, and the cam lever 90 is pushed down to get over the angle cam portion 90a. When the small-diameter guide boss 17 reaches the end of the guide groove 87, the cam lever 90 rises as shown in FIG. The entire binder cartridge 1 is locked without rattling by sandwiching the small-diameter guide boss 17 from above and below by the plate 88 and the cam lever 90. When removing the binder cartridge 1, as shown in FIG. 21 (b), the small-diameter guide boss 17 pushes down the cam lever 90 to get over the chevron cam portion 90a, and the binder cartridge 1 can be attached and detached without requiring a special unlocking operation. .

  The present invention is not limited to the above embodiment. In the above embodiment, an example in which two guide bosses are arranged before and after the binder cartridge has been described. However, two guide bosses are used instead of two separated guide bosses. A wedge-shaped plate with a boss shape may be provided, and various other modifications are possible within the technical scope of the present invention. Further, the technology of the present invention can be applied not only to the binder cartridge but also to a cassette or storage tray of paper or other consumables, and the present invention naturally extends to those modified ones.
