  By the way, the image forming apparatus mounted on the mounting table as described above has different appearance shape and installation area (area of the installed bottom) for each model. Therefore, in the conventional mounting table, it is necessary to prepare a dedicated mounting table whose specifications are changed for each model of the image forming apparatus, and there is a problem that the manufacturing cost increases. On the other hand, if a large mounting table suitable for the image forming apparatus of the maximum size that can be assumed is prepared, the mounting table can also be used for an image forming apparatus of a smaller size. When mounting a small image forming apparatus on a mounting table, there is a problem that an excess portion of the mounting table becomes an obstacle. In particular, when an image forming apparatus having a plurality of stages of paper feeding units is placed on the mounting table, the mounting table is made larger than the front, rear, left, and right widths of the image forming apparatus in order to prevent the image forming apparatus from tilting together with the mounting table. Therefore, the above-mentioned problem becomes remarkable.

  Therefore, the present invention provides a mounting table even when a small image forming apparatus is mounted while suppressing the mounting table on which a plurality of types of image forming apparatuses having different sizes can be tilted together with the image forming apparatus. The purpose is to suppress the obstruction.

In order to solve the above problems, a mounting table according to the present invention is a mounting table having a mounting surface on which an image forming apparatus is mounted, and a main body unit having a bottom portion having the mounting surface, and the main body unit A first projecting portion projecting upward from the bottom portion, and disposed at a center side of the mounting table before the first projecting portion, and downward from a position projecting upward from the bottom portion. A movable second protrusion, a first position protruding outward from the main body when the main body is viewed from above, and a second position retracted inward from the first position A moving member supported by the main body so as to be possible.
The moving member is configured to move from the second position to the first position in conjunction with an operation in which the second projecting portion moves downward.

  According to this configuration, when a small image forming apparatus is installed in the main body, the mounting table can be made compact by moving the moving member to the second position. At this time, even when the small image forming apparatus installed in the main body part is tilted together with the mounting table, the moving member positioned at the second position is in contact with the ground, so that further tilting can be suppressed. Specifically, when the image forming apparatus is small, if the moving member located at the second position retracted inward from the first position contacts the ground, the inclination can be sufficiently suppressed.

  In addition, since the moving member is located at the first position, the moving member positioned outside the side surface of the main body portion is in contact with the ground even when the large image forming apparatus installed in the main body portion is inclined. Therefore, the inclination beyond that can be suppressed. Specifically, a large image forming apparatus has a larger horizontal distance from the center of tilting to the upper part of the image forming apparatus even if the angle of inclination is the same, because the vertical length is larger than a small image forming apparatus. However, at this time, the moving member that is set to the first position outside the second position is supported by the ground, so that the falling is well suppressed.

  Further, in the above-described configuration, the moving member may be formed with an inclined surface that is inclined downward from the outside toward the inside, and the second projecting portion may be disposed on the inclined surface.

  According to this, since the structure which makes a 2nd protrusion part and a moving member interlock | cooperate can be comprised easily, a mounting base can be made into a simple structure.

  Moreover, in the above-described configuration, a first urging member that urges the moving member toward the second position may be provided.

  According to this, for example, in a configuration in which the second protrusion moves downward by placing the large image forming apparatus on the second protrusion, when the large image forming apparatus is removed from the main body, the moving member is Since the urging force of the one urging member automatically moves from the first position to the second position, the mounting table can be automatically made compact.

  Moreover, in the above-described configuration, a second urging member that urges the second projecting portion upward may be provided.

  According to this, for example, in a configuration in which the second protrusion moves downward by placing the large image forming apparatus on the second protrusion, the second biasing is performed when the large image forming apparatus is removed from the main body. The second protrusion can be automatically returned to the original position by the member.

  In the above-described configuration, the urging force of the second urging member can be greater than the urging force of the first urging member.

  When the urging force of the first urging member is larger than the urging force of the second urging member, the moving member is strongly pressed against the second protrusion by the urging force, and the second protrusion is unlikely to return to the original position. However, according to the above-described configuration, the urging force of the second urging member is made larger than the urging force of the first urging member, so that occurrence of such a problem can be suppressed. .

  Moreover, in the above-described configuration, the main body portion may be configured in a rectangular shape in plan view, and the moving member may be provided on each side surface of the main body portion.

  According to this, since the moving member is provided on each side surface of the main body, even if the image forming apparatus installed in the main body is inclined in any direction, any moving member can suppress further inclination. Can do.

  In the above-described configuration, the bottom portion may be formed in a rectangular shape in plan view, and the first protrusion may be provided only on three side end portions of the four side end portions of the bottom portion.

  In the case where the first projecting portions are provided on all the four side end portions of the bottom portion, the lowermost sheet feeding tray can be pulled out in a state where the sheet feeding unit of the image forming apparatus is installed inside each first projecting portion. In this way, the lower part of the paper feed unit below the paper feed tray is formed to be somewhat larger in the vertical direction, the part is placed in each first protrusion, and the paper feed tray is placed above each first protrusion. Need to be placed in. On the other hand, in the configuration described above, the inner space of the three first protrusions is opened to the outside through a portion where there is no first protrusion, so that the paper feed tray can be pulled out from the opened portion. Can do. Therefore, the lower surface of the paper feed tray can be disposed below the upper ends of the first protrusions, so that the paper feed unit can be downsized in the vertical direction.

  Further, in the above-described configuration, the bottom is configured in a rectangular shape in plan view, the first protrusion is provided at four side end portions of the bottom, and the upper surface of one first protrusion is another You may arrange | position in the position lower than the upper surface of a 1st protrusion part.

  According to this, since the upper surface of one 1st protrusion part is arrange | positioned in the position lower than the upper surface of the other 1st protrusion part among the 4 1st protrusion parts, A space is opened to the outside through a space above the low first protrusion. Therefore, since the paper feed tray can be pulled out using the space above the low first protrusion, the lower surface of the paper feed tray can be arranged below the upper end of each first protrusion, The paper unit can be downsized in the vertical direction.

  Further, in the above-described configuration, one spacer member that separates the lower surface from the installation surface on which the mounting table is installed is provided at each corner of the lower surface of the main body unit. The supported portion that is movably supported may be disposed between the two spacer members on one side of the lower surface of the main body portion.

  When the supported portion of the moving member is arranged above the spacer member, the main body portion needs to be enlarged in the vertical direction in order to secure a portion for attaching the spacer member. By disposing the supported portion between the spacer members, it is possible to suppress an increase in size of the main body portion in the vertical direction.

  Moreover, the above-mentioned structure WHEREIN: The lower surface of the outer edge part among the said moving members may be arrange | positioned in the range of the said spacer member in an up-down direction.

  According to this, since the lower surface of the outer end portion of the moving member can be brought close to the ground, the lower surface of the outer end portion of the moving member can be immediately attached to the ground when the image forming apparatus is tilted. The inclination of the image forming apparatus can be suppressed more favorably.

  In the configuration described above, the lower surface of the outer end portion of the moving member may be wider than the supported portion in the direction along the one side.

  According to this, since the contact area between the moving member and the ground can be increased, the inclination of the image forming apparatus can be suppressed more favorably.

The mounting table according to the present invention is a mounting table on which the first image forming apparatus can be mounted and a second image forming apparatus larger than the first image forming apparatus can be mounted. A main body supporting the first image forming apparatus or the second image forming apparatus from below; a first position protruding outward from a side surface of the main body; and a second position retracted inward from the first position. The moving member that is supported by the main body so as to be movable and the load of the second image forming apparatus is changed to a force in a direction from the second position toward the first position, and the moving member And a force conversion unit to be transmitted.
The moving member is movable to both the first position and the second position when the first image forming apparatus is installed in the main body, and when the moving member is located at the second position. When the second image forming apparatus is installed in the main body, the load of the second image forming apparatus is transferred from the second position to the first position by being transmitted through the force conversion unit. To do.

  According to this configuration, when the small first image forming apparatus is installed in the main body, the mounting table can be made compact by moving the moving member to the second position. At this time, even when the small first image forming apparatus installed in the main body is tilted together with the mounting table, the moving member positioned at the second position is in contact with the ground, thereby suppressing further tilting. it can. Specifically, since the first image forming apparatus is small, if the moving member located at the second position retracted inward from the first position is in contact with the ground, the tilt can be sufficiently suppressed.

  Further, since the moving member is positioned at the first position, the moving member positioned outside the side surface of the main body portion is on the ground even when the large second image forming apparatus installed in the main body portion is tilted. By touching, further inclination is suppressed. Specifically, the large second image forming apparatus has a larger vertical length than the small first image forming apparatus, and the horizontal direction from the center of tilting to the top of the image forming apparatus is the same even though the inclination angle is the same. However, at this time, the moving member that is set to the first position outside the second position is supported by the ground, so that the falling is suppressed well.

  Further, when the second image forming apparatus is placed on the main body when the moving member is positioned at the second position, the load of the second image forming apparatus is transmitted to the moving member via the force conversion unit. The moving member automatically moves from the second position to the first position. Therefore, even if the user forgets to adjust the mounting table to the size of the large second image forming apparatus, the moving member is the first corresponding to the second image forming apparatus only by placing the second image forming apparatus on the mounting table. Can be automatically placed in position.

  Moreover, in the above-described configuration, the force conversion portion may be an inclined surface that is formed on the moving member and is inclined downward as it goes from the outside to the inside.

  According to this, since a force conversion part can be comprised simply, a mounting base can be made into a simple structure.

  Further, in the above-described configuration, the main body portion includes an intermediate member supported on the main body portion so as to be movable in the vertical direction and disposed on the inclined surface of the moving member located at the second position. A bottom portion that supports the first image forming apparatus or the second image forming apparatus from below, and protrudes upward from the bottom portion, and comes into contact with a side surface of the second image forming apparatus, thereby causing a horizontal direction of the second image forming apparatus And the intermediate member is disposed inside the wall and is in contact with a side surface of the first image forming apparatus so as to be in a horizontal direction of the first image forming apparatus. It can be set as the structure which controls a movement.

  According to this, when the first image forming apparatus is installed at the bottom, the movement of the first image forming apparatus is restricted by the side surface of the first image forming apparatus coming into contact with the intermediate member. Can be installed. When the second image forming apparatus is installed at the bottom, the moving member moves from the second position to the first position by pushing down the intermediate member by the second image forming apparatus. Further, when the intermediate member is lowered, the horizontal movement of the second image forming apparatus on the intermediate member is restricted by the wall portion, so that the second image forming apparatus can be installed at a desired location.

  According to the present invention, it is possible to prevent the mounting table on which a plurality of types of image forming apparatuses having different sizes can be placed from being tilted together with the image forming apparatus, and even when a small image forming apparatus is mounted. , The mounting table can be prevented from getting in the way.

Next, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
As shown in FIG. 1, the mounting table 1 is a table on which a small printer unit PU1 as an example of a first image forming apparatus and a large printer unit PU2 as an example of a second image forming apparatus can be mounted. The mounting table 1 includes a main body 10 having a rectangular shape in plan view, four moving members 20 provided on each of the four side surfaces 10A of the main body 10, and an intermediate as an example of a second protrusion provided in the main body 10. The member 30 and four casters 40 as an example of a spacer member are provided. Here, the small printer unit PU1 includes a small printer PU11 and three small paper feed units PU12 connected to the lower portion of the small printer PU11. The large printer unit PU2 is larger than the small printer unit PU1 in the up / down, front / rear, and left / right directions, and includes a large printer PU21 and three large paper feed units PU22 connected to the lower portion of the large printer PU21. ing.

  In the present specification, the direction will be described with reference to the direction shown in FIG. 1, that is, the direction based on the user when using the printer units PU1 and PU2.

  The main body 10 includes a bottom portion 11 having a rectangular shape in plan view that supports the small printer unit PU1 or the large printer unit PU2 from below, and a first projecting portion and a wall projecting upward from the front, rear, left, and right side end portions of the bottom portion 11 It has four side wall parts 12 as an example of a part. As shown in FIGS. 2 and 3, the bottom 11 has a bottom main body 11A formed with a front / rear width and a left / right width larger than the front / rear width and the left / right width of the large printer unit PU2, and upward from the center of the bottom main body 11A. And a bulging portion 11B that bulges. The bulging portion 11B is configured in a rectangular shape in plan view, and its front-rear width and left-right width are slightly larger than the front-rear width and left-right width of the small printer unit PU1. That is, the upper surface of the bulging portion 11B is a first placement surface for placing the small printer unit PU1.

  The side wall part 12 protrudes above the bulging part 11B, and its inner surface 12A is arranged at a position corresponding to the side surface of the large-sized printer unit PU2. Specifically, the interval between the pair of side wall portions 12 arranged in the front-rear direction is slightly larger than the front-rear width of the large printer unit PU2, and the interval between the pair of side wall portions 12 arranged in the left-right direction is larger than the left-right width of the large printer unit PU2. Slightly larger.

  A distance L1 in the vertical direction from the upper surface of the side wall portion 12 to the upper surface of the bulging portion 11B is a distance L2 from the lower surface of the small paper feed unit PU12 shown in FIG. 1 to the lower surface of the paper feed tray T1 of the small paper feed unit PU12. Is smaller than The distance from the lower surface of the small printer PU11 to the lower surface of the paper feed tray T1 of the small printer PU11, the distance from the lower surface of the large printer PU21 to the lower surface of the paper feed tray T2 of the large printer PU21, and the large paper feed unit The distance from the lower surface of the PU 22 to the lower surface of the paper feed tray T2 of the large-size paper feed unit PU22 may be a size equal to or greater than the distance L2. This makes it possible to prevent the paper feed tray T2 from interfering with the side wall portion 12 when the paper feed tray T2 is pulled out.

  In addition, support holes 12B that support the movable member 20 so as to be movable in the horizontal direction are formed in the central portion of the lower portions of the side wall portions 12, respectively. As shown in FIG. 3, 11 C of spring accommodating parts for accommodating the tension coil spring S1 as an example of the 1st biasing member are each formed under each support hole 12B.

  When the main body 10 is viewed from above, the moving member 20 is retracted to the inner side of the first position (the position of FIG. 3B) protruding outward from the side surface 10A of the main body 10 and the first position. However, it is supported by the main body 10 so as to be movable to the second position (position shown in FIG. 3A). In the present embodiment, the moving member 20 protrudes outside the side surface 10A of the main body 10 even at the second position. However, the present invention is not limited to this, and the moving member is the main body at the second position. It may be a position retracted inward from the side surface.

  The moving member 20 includes a supported portion 21 supported by the support hole 12 </ b> B of the main body portion 10, and an extending portion 22 that extends downward from an outer end portion of the supported portion 21. When the movable member 20 is located at the second position, the supported portion 21 has an inner end in contact with the bulging portion 11B.

  An inclined surface 21 </ b> A as an example of a force conversion portion that is inclined downward from the outer side to the inner side in the horizontal direction is formed at the upper portion of the inner end portion of the supported portion 21. 21 A of inclined surfaces are arrange | positioned between the side wall part 12 and the bulging part 11B when the moving member 20 is located in a 2nd position, and are formed ranging from the side wall part 12 to the bulging part 11B.

  The lower surface 22A of the extending portion 22 is disposed within the range of the wheels 41 of the casters 40 in the vertical direction. Specifically, the lower surface 22A is disposed below the horizontal plane FF passing through the rotation axis 41A of the wheel 41. The position of the lower surface 22A should be closer to the installation surface F of the mounting table 1 in order to exert the effect of suppressing the inclination of the printer units PU1 and PU2, but the movement when the mounting table 1 is moved by the casters 40 In consideration of ease of operation, it may be set so as to be separated from the installation surface F as appropriate.

  The extending portion 22 is in contact with the side surface 10A of the main body portion 10 when the moving member 20 is located at the second position. And between the extension part 22 and the main-body part 10, the tension | pulling coil spring S1 which urges | biases the moving member 20 toward a 2nd position is provided.

  As shown in FIG. 1, the intermediate member 30 is a rectangular frame-shaped member, and its four inner surfaces 31 are formed at positions corresponding to the four side surfaces of the small printer unit PU1. Specifically, the distance between the pair of inner surfaces 31 arranged in the front-rear direction is slightly larger than the front-rear width of the small printer unit PU1, and the distance between the pair of inner surfaces 31 arranged in the left-right direction is slightly larger than the left-right width of the small printer unit PU1. It has become.

  Further, the four outer surfaces 32 (see FIG. 3) of the intermediate member 30 are formed at positions corresponding to the four side surfaces of the large-sized printer unit PU2. Specifically, the distance between the pair of outer surfaces 32 arranged in the front-rear direction is slightly larger than the front-rear width of the large printer unit PU2, and the distance between the pair of outer surfaces 32 arranged in the left-right direction is slightly larger than the left-right width of the large printer unit PU2. It has become. That is, the upper surface of the intermediate member 30 is a second placement surface for placing a portion of the large printer unit PU2 that protrudes outward from the first placement surface.

  The intermediate member 30 is supported by the main body 10 so as to be movable in the vertical direction so as to be movable between an upper position shown in FIG. 3A and a lower position shown in FIG. . Specifically, the intermediate member 30 is disposed closer to the center of the mounting table 1 than the side wall portion 12 of the main body portion 10, and is supported so as to be movable in the vertical direction between the side wall portion 12 and the bulging portion 11B. .

  The intermediate member 30 protrudes upward from the bulging portion 11B at the upper position, and the upper surface thereof is flush with the upper surface of the side wall portion 12, and at the lower position, the upper surface is flush with the upper surface of the bulging portion 11B. And the magnitude | size of an up-down direction is set so that the lower surface may contact the upper surface of 11 A of bottom main bodies. The four corners of the intermediate member 30 are supported by four compression coil springs S2 as an example of the second urging member shown in FIGS.

  The compression coil spring S2 is disposed between the intermediate member 30 and the bottom main body 11A, and urges the intermediate member 30 toward the upper position. Specifically, the compression coil spring S2 is housed in a first housing recess 34 formed at one end on the lower surface of the intermediate member 30, and housed in a second housing recess 11D formed at the bottom body 11A. . The biasing force of the compression coil spring S2 is larger than the biasing force of the tension coil spring S1.

  And the intermediate member 30 is arrange | positioned on 21 A of inclined surfaces of the moving member 20 located in a 2nd position by being supported by compression coil spring S2, as shown in FIG. Specifically, a contact surface 33 formed along the inclined surface 21A and in surface contact with the inclined surface 21A is formed on the outer side of the lower portion of the intermediate member 30. One contact surface 33 is provided for each of the four sides of the intermediate member 30 so as to correspond to the four moving members 20.

  Accordingly, as shown in FIGS. 3 and 5, when the intermediate member 30 is pushed down from the upper position to the lower position, a force applied to the intermediate member 30 in the vertical direction is applied to the inclined surface 21 </ b> A via the contact surface 33. Thus, it is converted into a force directed outward in the horizontal direction (force directed from the second position to the first position) and transmitted to the moving member 20, so that the moving member 20 moves outward. That is, the moving member 20 is moved from the second position to the first position in conjunction with the movement of the intermediate member 30 moving downward. When the force applied to the intermediate member 30 at the lower position is released, the intermediate member 30 returns to the upper position by the biasing force of the compression coil spring S2, and the moving member 20 is moved to the second inner position by the biasing force of the tension coil spring S1. To come back.

  As shown in FIGS. 2 and 3, the caster 40 is a member for separating the lower surface of the main body 10 from the installation surface F, and is provided at four corners of the lower surface of the main body 10. And a support mechanism 42 that rotatably supports 41. The support mechanism 42 is a known mechanism configured to be able to change the direction of the wheel 41 in the horizontal direction by 360 °, and is attached to the lower surface of the main body portion 10 by screws or the like (not shown). The supported portion 21 of the moving member 20 described above is disposed between the two casters 40 on each side of the lower surface of the main body portion 10.

Next, a method for using the mounting table 1 will be described.
As shown in FIG. 1, when the small printer unit PU <b> 1 is placed on the mounting table 1, first, the small paper feed unit PU <b> 12 is inserted into the intermediate member 30 and placed on the bulging portion 11 </ b> B of the main body portion 10. As a result, as shown in FIG. 6, the movement of the small paper feed unit PU12 in the front-rear and left-right directions is restricted by contact with the intermediate member 30, so that the small paper feed unit PU12 is placed on the mounting table 1 by a fixture (not shown). Can be prevented from shifting in the front-rear and left-right directions, and the small-size paper feed unit PU12 can be maintained at a desired position.

  When the small paper feeding unit PU12 is set on the mounting table 1 in this way, the intermediate member 30 does not move from the upper position, and thus the moving member 20 does not move from the second position which is the initial position. It remains in position 2. Further, the moving member 20 located at the second position can be moved to the first position by the user pulling it toward the first position by hand, but when the user releases the hand, the moving coil 20 of the tension coil spring S1 is moved. The urging force automatically returns to the second position.

  Thereafter, the remaining small paper feed unit PU12 and the small printer PU11 are stacked on the small paper feed unit PU12 fixed to the mounting table 1, and the small printer PU11 and each small paper feed unit PU12 are not illustrated as appropriate. Fix with a fixture. Through the above operations, the small printer unit PU1 is set on the mounting table 1.

  When the mounting table 1 on which the small printer unit PU1 is set is moved to the right side, for example, the right caster 40 strikes an obstacle on the installation surface F and the small printer unit PU1 is tilted to the right together with the mounting table 1. In such a case, the right-side moving member 20 located at the second position is in contact with the installation surface F, and further inclination is restricted. Specifically, since the small printer unit PU1 is smaller in the vertical direction than the large printer unit PU2, when the moving member 20 located at the second position retracted inward from the first position contacts the installation surface F, the tilt center The amount (horizontal distance) that the upper portion of the small printer unit PU1 protrudes from (for example, the caster 40) is small. Therefore, even the moving member 20 located at the second position can sufficiently suppress the inclination of the small printer unit PU1.

  As shown in FIG. 1, when the large printer unit PU2 is placed on the mounting table 1, first, the large paper feed unit PU22 is placed on the intermediate member 30, and the intermediate member 30 is attached with the compression coil spring S2 together with the large printer unit PU2. Lower down against the forces. As a result, as shown in FIGS. 7 and 3B, the large paper feed unit PU22 enters the four side walls 12, and the large paper feed unit PU22 is supported by the bulging portion 11B and the intermediate member 30. .

  In this way, the large paper feed unit PU22 enters the four side wall portions 12 so that the movement of the large paper feed unit PU22 in the front-rear and left-right directions is restricted by contact with the side wall portions 12. Therefore, when the large paper feed unit PU22 is fixed to the mounting table 1 with a fixture (not shown), it is possible to suppress the position of the large paper feed unit PU22 from being shifted in the front-rear and left-right directions. Can be maintained in the desired position.

  At this time, the load of the large paper feeding unit PU22 is transmitted to the inclined surface 21A of the moving member 20 via the contact surface 33 of the intermediate member 30, so that the direction is changed and transmitted to each moving member 20. Therefore, each moving member 20 moves so as to spread outward against the urging force of the tension coil spring S1 and is positioned at the second position by this load.

  Thereafter, the remaining large paper feed unit PU22 and large printer PU21 are stacked on the large paper feed unit PU22 fixed to the mounting table 1, and the large printer PU21 and each large paper feed unit PU22 are not illustrated as appropriate. Fix with a fixture. Through the above operation, the large printer unit PU2 is set on the mounting table 1.

  When the mounting table 1 on which the large printer unit PU2 is set is moved to the right side, for example, the right caster 40 strikes an obstacle on the installation surface F and the large printer unit PU2 is tilted to the right together with the mounting table 1. In such a case, the right-side moving member 20 located at the first position outside the second position is in contact with the installation surface F, whereby further inclination is restricted. Here, when the position of the moving member 20 is the second position, the angle of the large printer unit PU2 in a state where the moving member 20 is in contact with the installation surface F is the same as the angle when the small printer unit PU1 is inclined. Since the large printer unit PU2 is larger in the vertical direction than the small printer unit PU1, the amount that the upper portion of the large printer unit PU2 protrudes from the tilting center is larger than when the small printer unit PU1 is tilted. There is a risk of falling.

  On the other hand, in the present embodiment, when the large printer unit PU2 is set on the mounting table 1, the moving member 20 is positioned at the first position outside the second position, so the angle of the large printer unit PU2 is set. The angle when the small printer unit PU1 is tilted can be made smaller. As a result, the amount by which the upper portion of the large printer unit PU2 protrudes from the tilt center can be reduced, so that the inclination of the large printer unit PU2 can be satisfactorily suppressed by the moving member 20 located at the second position.

As described above, according to the present embodiment, the following effects can be obtained in addition to the effects described above.
When the small printer unit PU1 is installed on the mounting table 1, since the moving member 20 is disposed at the second position, the mounting table 1 can be made compact.

  Since the tension coil spring S1 that biases the moving member 20 toward the second position is provided, when the large printer unit PU2 is removed from the mounting table 1, the moving member 20 is moved to the first position by the biasing force of the tension coil spring S1. To the second position automatically. For this reason, for example, when the large-sized printer unit PU2 is removed from the mounting table 1 when the office is moved, the mounting table 1 can be automatically reduced to a compact size. Can be easily performed.

  Since the compression coil spring S2 that urges the intermediate member 30 toward the upper position is provided, when the large printer unit PU2 is removed from the mounting table 1, the intermediate member 30 is returned to the original upper position by the urging force of the compression coil spring S2. Can be returned automatically.

  Since the urging force of the compression coil spring S2 is greater than the urging force of the tension coil spring S1, the intermediate member 30 can be reliably returned from the lower position to the upper position. Specifically, if the urging force of the tension coil spring S1 is larger than the urging force of the compression coil spring S2, the moving member 20 is strongly pressed against the intermediate member 30 by the urging force, and the intermediate member 30 is unlikely to return to the original upper position. However, according to the configuration described above, occurrence of such a problem can be suppressed.

  Since the moving member 20 is provided on each side surface 10A of the main body 10, even if the printer units PU1 and PU2 installed on the main body 10 are inclined in any direction, any moving member 20 causes the inclination further. Can be suppressed.

  Since the supported portion 21 of the moving member 20 is disposed between the two casters 40 on each side of the lower surface of the main body portion 10, for example, the supported portion of the moving member is disposed above the caster. Compared with the structure, the main body 10 can be prevented from being enlarged in the vertical direction. Specifically, when the supported portion of the moving member is arranged above the caster, the main body needs to be enlarged in the vertical direction in order to secure a portion for attaching the caster. By comprising in this way, the enlargement to the up-down direction of the main-body part 10 can be suppressed.

  By arranging the lower surface 22A of the extending portion 22 of the moving member 20 within the range of the wheel 41 of the caster 40 in the vertical direction, it can be brought closer to the installation surface F, so that when the printer units PU1 and PU2 are inclined In addition, the moving member 20 can be immediately attached to the installation surface F, and the inclination of the printer units PU1 and PU2 can be satisfactorily suppressed.
