The present invention relates to a sheet loading device applied to an image forming apparatus and including a sheet loading tray on which a plurality of sheets is loaded.
Generally, an image forming apparatus such as a printing apparatus that prints images and characters on sheets or a copy machine that copies images and characters thereon includes a sheet loading device including a sheet loading tray on which a plurality of sheets are loaded.
This type of a sheet loading device is used as a paper feed device that feeds, one by one, a plurality of sheets loaded on the sheet loading tray to the image forming apparatus. Alternatively, the sheet loading device is used as a paper discharge device that sequentially loads, on the sheet loading tray, sheets having the images formed which have been discharged from the image forming apparatus.
An example of the sheet loading device includes a paper discharge device in a stencil printing machine using the sheet loading tray as a paper receiving tray disclosed in Patent Literature 1 (Japanese Patent Application Publication No. 08-208096).
The paper discharge device in the stencil printing machine disclosed in Patent Literature 1 is rotatably mounted with a paper receiving tray (sheet loading tray) on a side of a one side surface of a casing between a sheet loading position (inclined position) and a paper receiving tray storage position (erected position).
When the paper receiving tray is located at the sheet loading position, the paper receiving tray is inclined toward an outside from the one side surface of the casing of the stencil printing machine (described as a printing unit in Patent Literature 1) to thereby allow loading of a plurality of sheets. When the paper receiving tray is located at the paper receiving tray storage position, the paper receiving tray is in a state of being erected along the one side surface of the casing to be stored.
Furthermore, the paper receiving tray is held in a state of being erected with a magnet mounted on the side of the one side surface of the casing at the paper receiving tray storage position. The paper receiving tray is detachable from the side of the one side surface of the casing, with the plurality of sheets loaded at the sheet loading position.
According to the paper discharge device included in the stencil printing machine configured as described above, there is no generation of offset on each sheet, since the paper receiving tray is removed from the casing with a great number of printed sheets loaded and is moved to other storage place, and thus pressure caused by operator's hands and fingers onto printed matter cannot be applied during movement.
Furthermore, a plurality of paper receiving trays is prepared in advance and a new, empty paper receiving tray is mounted to the one side surface of the casing in place of the removed paper receiving tray. Thus, next printing can be instantly started, and the printing can be efficiently performed by elimination of a waste of printing time due to leaving the printed matters behind.
The paper discharge device included in the stencil printing machine described in the Patent Literature 1 uses a magnet as a holding member that holds the paper receiving tray in a state (a state where the paper receiving tray is at the paper receiving tray storage position (erected position)) where the paper receiving tray (sheet loading tray) is erected along the one side surface of the casing.
However, a holding force of the magnet is not stable and, thus, when the holding force thereof is weak, there is a case where the paper receiving tray suddenly falls down by a slight contact, thereby causing danger. Furthermore, there is also a case where the paper receiving tray or parts around it may be damaged by the force of falling down.
On the other hand, when the holding force of the magnet is strong, a great force is required when the paper receiving tray is removed from the casing. Therefore, a dangerous case may occur since an excessively strong force is given when the force is applied.
Accordingly, an object of the present invention is to provide a sheet loading device in which a sheet loading tray that loads a plurality of sheets is rotatably mounted between a sheet loading position and a sheet loading tray storage position on a side of a one side surface of a casing of an image forming apparatus. Further, when the sheet loading tray is configured to be detachable from the side of the one side surface of the casing at the sheet loading position, the sheet loading tray can be reliably locked and held without the use of a magnet in a state where the sheet loading tray is erected along the one side surface of the casing at the sheet loading tray storage position.
The present invention has been made in consideration of the problem described above. A first invention is a sheet loading device in which in which a sheet loading tray that loads a plurality of sheets, between a sheet loading position where the sheet loading tray is inclined outwardly from a one side surface of a casing of an image forming apparatus to load the sheet and a sheet loading tray storage position where the sheet loading tray is erected along the one side surface to be stored, is rotatably mounted on a side of the one side surface of the casing, and furthermore, the sheet loading tray is detachable from the side of the one side surface at the sheet loading position, the sheet loading device comprising:
right and left first brackets whose each side of one-end parts is fixed to each outside of right and left side surfaces on a side of a front side surface of the sheet loading tray facing the one side surface of the casing, and whose each side of other-end parts protrudes toward the one side surface thereof;
a lock pin laterally provided on each side of one-end parts of the right and left first brackets;
a rotational pin laterally provided on each side of other-end parts of the right and left first brackets
right and left second brackets whose each side of one-end parts is fixed to each of right and left one side surfaces of the casing, and whose each side of other-end parts protrudes toward each of right and left side surface sides of the sheet loading tray;
a sheet loading tray lock groove into/from which the each lock pin is inserted/detached with an upper part close to each side of one-end parts being opened in an upper part of each side of the other end parts of the right and left second brackets, and
a sheet loading tray lock groove into/from which the each rotational pin is inserted/detached with an upper part away from each side of one-end parts being opened in an upper part of each side of the other end parts of the right and left second brackets,
wherein, when the sheet loading tray reaches the sheet loading position, the lock pin is made to enter the sheet loading tray lock groove formed on the right and left second brackets to lock and hold the sheet loading tray at the sheet loading tray storage position, along with an action of rotating the sheet loading tray about the rotational pin fitting into the sheet loading tray support groove formed on the right and left second brackets from the sheet loading position to the sheet loading tray storage position.
Furthermore, a second invention is the sheet loading device of the first invention, wherein, between the sheet loading tray support groove and the sheet loading tray lock groove, the right and left second brackets are formed with each curved cam part on which the lock pin slides along with an action of rotating the sheet loading tray from the sheet loading position to the sheet loading tray storage position.
Hereinafter, an embodiment of the sheet loading device according to the present invention will be described in detail with reference to
The sheet loading device according to the present invention is applied to printing apparatuses that print images and characters on sheets, and image forming apparatuses such as copy machines that copy images and characters thereon.
The sheet loading device according to the present invention is used as a paper feed device that feeds, one by one, a plurality of sheets loaded on the sheet loading tray into the image forming apparatus. Alternatively, the sheet loading device is used as a paper discharge device that sequentially loads, on the sheet loading tray, sheets having images formed which have been discharged from the image forming apparatus.
Hereinafter, there will be described, with reference to
First, as illustrated in
In the casing 2, a first opening part 2b1 is opened at an upper site of a one side surface 2b serving as one of side surfaces on which the sheet loading device 10 according to the present invention is provided. A sheet loading tray 11 that loads a plurality of sheets P is rotatably (openably and closably) and detachably mounted facing the first opening part 2b 1 in a state of protruding to the outside of the one side surface 2b of the casing 2.
Note that, in the following description, “front, back, right and left” are defined as those on the basis of a direction in which a side of the one side surface 2b of the casing 2 is viewed from a side of the sheet loading device 10. In other words, “front” and “back” mean “forward” and “backward”, respectively, in a direction toward the side of the one side surface 2b of the casing 2 from the side of the sheet loading device 10. Furthermore, “right” and “left” mean “right side” and “left side” viewed from a front, respectively, when the side of the one side surface 2b of the casing 2 is viewed from the side of the sheet loading device 10.
A second opening part 2c1 is opened at an upper site of the other side surface 2c of the casing 2, which faces the one side surface 2b with the casing 2 therebetween. An external paper feed tray 4 that loads the sheet P for manual paper feed is mounted facing the second opening part 2c1 as necessary in a state of protruding outwardly from the other side surface 2c. Note that, in a substantially similar manner to the sheet loading device 10 according to the present invention, the external paper feed tray 4 may be rotatably (openably and closably) provided on the other side surface 2c of the casing 2. Furthermore, the external paper feed tray 4 may be detachably provided on the other side surface 2c of the casing 2.
Furthermore, the plurality of internal paper feed trays 5A to 5C is provided corresponding to an outer size of the sheet P at a side of the other side surface 2c in the casing 2. The internal paper feed trays 5A to 5C are provided such that they can be pulled out of the casing 2.
Moreover, the casing 2 is provided with a paper feed unit 6 that selectively feeds, one by one, the sheets P on the external paper feed tray 4 or the sheets P in the plurality of internal paper feed trays 5A to 5C, an image forming unit 7 that forms the image on the sheets P conveyed from the paper feed unit 6, a paper discharge unit 8 that discharges the sheets P which have been processed to thereby be formed with the image in the image forming unit 7, and a controller 9 that totally controls the image forming apparatus 1.
In addition, the sheet loading tray 11 mounted outside the one side surface 2b of the casing 2 functions as a paper receiving tray that loads the sheets P with the image formed which have discharged from the paper discharge unit 8.
An end fence plate 12 that restricts a leading end of the sheet P in a sheet discharge direction D is provided movably, on the upper surface 11a of the sheet loading tray 11 (paper receiving tray), in the sheet discharge direction D depending on a length of the sheet P and foldably toward an inside when the sheet loading tray 11 is stored.
Furthermore, a pair of right and left side fence plates 13R and 13L that restrict both side ends of the sheet P in a width direction thereof are provided movably, on the upper surface 11a of the sheet loading tray 11, in the width direction of the sheet orthogonal to the sheet discharge direction D depending on a width dimension of the sheets P, and foldably inwardly with each other when the sheet loading tray 11 is stored.
Moreover, the sheet loading tray 11 is rotatably mounted on the side of the one side surface 2b of the casing 2 between the sheet loading position (inclined position) where the sheet loading tray 11 is inclined up to an angle with which the sheet loading tray is located slightly lower than a horizontal line outwardly from the one side surface 2b of the casing 2 and loads the plurality of sheets P, and the sheet loading tray storage position (erected position) where the sheet loading tray 11 is substantially vertically erected along the one side surface 2b of the casing 2. Furthermore, the sheet loading tray 11 is set detachable from the one side surface 2b of the casing 2, with the sheets P loaded at the sheet loading position.
Here, a configuration of the sheet loading device 10 according to the present invention will be described by the use of
At this sheet loading position, the sheet loading tray 11 rotatably supported at a substantially intermediate site of the one side surface 2b of the casing 2 in a height direction is inclined at a predetermined angle (substantially 100 degrees) to the one side surface 2b of the casing 2.
Then, the sheets P discharged toward the sheet discharge direction D by a pair of paper discharge rollers 8a of the paper discharge unit 8 provided in the casing 2 are sequentially loaded on the upper surface 11a of the sheet loading tray 11.
Furthermore, as described below, since the sheet loading tray 11 is detachably supported on the one side surface 2b of the casing 2 at this sheet loading position, the sheet loading tray 11 can be removed from the side of the one side surface 2b of the casing 2, with the plurality of sheets P loaded on the sheet loading tray 11.
On the other hand,
At this sheet loading tray storage position, the end fence plate 12 and the pair of the right and left side fence plates 13R and 13L which are provided on the sheet loading tray 11 can be each folded inwardly to thereby be capable of being stored in the first opening part 2b1 opened in the one side surface 2b of the casing 2.
Then, the side of the upper surface 11a of the sheet loading tray 11 and the one side surface 2b of the casing 2 are made to face each other, and thus the sheet loading tray 11 is substantially vertically erected.
Therefore, at the time of conveyance of the image forming apparatus 1, or at the time of non-use when the sheet loading tray 11 loads the plurality of sheets P, the sheet loading tray 11 does not become obstructive, and thus the sheet loading device 10 can be made compact.
Returning to
Here, on the upper surface 11a of the sheet loading tray 11, a flat surface 11a1 is formed at a center in the sheet width direction along the sheet discharge direction D, and further, inclined surfaces 11a2 and 11a3 are inclined upward along the sheet width direction at both right and left sides of the flat surface 11a1 to be formed symmetrical bilaterally.
Then, right and left side end parts in the sheet width direction of the sheet P loaded on the upper surface 11a of the sheet loading tray 11 are lifted by the flat surface 11a1 and the right and left inclined surfaces 11a3, 11a2 to be stiffened.
Furthermore, the sheet loading tray 11 is mounted with right and left first brackets 14R and 14L. The right and left first brackets 14R and 14L are mounted respectively at positions of right and left side surfaces 11d and 11c of the sheet loading tray 11, and the positions are located on a side of a front side surface 11b facing the one side surface 2b of the casing 2. Each side of one-end parts of the right and left first brackets 14R and 14L is fixed to the sheet loading tray 11 by the use of a screw 15, and further, each side of other-end parts of the right and left first brackets 14R and 14L protrudes toward the side of the one side surface 2b of the casing 2.
The right and left first brackets 14R and 14L described above are formed in a plate-like shape by the use of a plate material as illustrated in enlarged views in
Moreover, the right and left first brackets 14R and 14L are formed such that each side of one-end parts 14a mounted on the right and left side surfaces 11d and 11c of the sheet loading tray 11 has substantially the same height dimension as those of the right and left side surfaces 11d and 11c, and dimension of each side of the one-end parts 14a in a longitudinal direction is formed longer. In addition, a screw mounting holes 14a1 through which the screws 15 (
Furthermore, the right and left first brackets 14R and 14L are formed such that each side of other-end parts 14b opposite to each side of the one-end parts 14a is higher than each side of the one-end parts 14a, and a leading end of each side of the other-end parts 14b is formed in the R-like shape. In addition, a rotational pin 16 with leading end flange part is laterally provided, outwardly in each side of the other-end parts 14b.
Moreover, the right and left first brackets 14R and 14L are formed such that each of intermediate upper parts 14c between each side of the one-end parts 14a and each side of the other-end parts 14b is slightly higher than each side of the other-end parts 14b, and dimension of the each of the intermediate upper parts 14c in the longitudinal direction is shorter than each side of the other-end parts 14b. In addition, a lock pin 17 with leading end flange part is laterally provided, outwardly in each of the intermediate upper parts 14c.
Furthermore, in the right and left first brackets 14R and 14L, each of intermediate lower parts 14d between each side of the one-end parts 14a and each side of the other-end parts 14b protrudes more downwardly than each side of the one-end parts 14a and each side of the other-end parts 14b. There is formed, in a concave shape, a concave part 14e for engaging a stopper pin which engages with each stopper pin 20 laterally provided in right and left second brackets 18R and 18L (
Then, the right and left first brackets 14R and 14L use the same components to reduce the number of components. However, the rotational pin 16 and the lock pin 17 are laterally provided, outwardly, in a horizontally symmetrical manner, and thus the right and left first brackets 14R and 14L are fixed in the horizontally symmetrical manner on the right and left side surfaces 11d and 11c of the sheet loading tray 11.
Returning to
Then, each one-end side of the right and left second brackets 18R and 18L are fixed by the use of a screw 19 on each inside side surface of the right and left frame members 2R and 2L at a substantially intermediate site in the height direction, and furthermore, each other-end side of the right and left second brackets 18R and 18L protrudes toward each side of right and left side surfaces 11d and 11c of the sheet loading tray 11.
The right and left second brackets 18R, 18L described above are formed by folding a sheet metal material used, as illustrated in an enlargement view in
Furthermore, the right and left second brackets 18R and 18L are formed such that each side of one-end parts 18a mounted on each inside surface at a substantially intermediate site in a height direction of the right and left frame members 2R and 2L is formed to be a square flat surface, and furthermore, a screw tap 18a1, to which screws 19 (
Moreover, the right and left second brackets 18R and 18L are folded such that each side of the other-end parts 18b opposite to each side of the one-end parts 18a protrudes one step more rightward or leftward than each side of the one-end parts 18a, and furthermore, they are formed such that each side of the other-end parts 18b in the height direction is larger than each side of the one-end parts 18a, and longer than each side of the one-end parts 18a in the longitudinal direction to thereby be formed in the plate-like shape. In addition, the upper part of each side of the other-end parts 18b becomes lower as being apart from each side of the one-end parts 18a.
Then, in the upper part at each side of the other-end parts 18b of the right and left second brackets 18R and 18L, a sheet loading tray lock groove 18b1, a curved cam part 18b2 (R part), a first straight-line inclination part 18b3, a sheet loading tray support groove 18b4, a first horizontal straight-line part 18b5, a second horizontal straight-line part 18b6, and a second straight-line inclination part 18b7 are sequentially formed from each side of the one-end parts 18a to each of the other-end back parts.
An upper part of the sheet loading tray lock groove 18b1 is formed such that there can be inserted/detached the lock pin 17 (
In addition, the curved cam part 18b2 is formed in a curved shape (R-like shape) from the sheet loading tray lock groove 18b1 toward the first straight-line inclination part 18b3 located below the curved cam part 18b2, and thus there can be slid the lock pin 17 laterally provided in the right and left first brackets 14R and 14L.
Furthermore, the first straight-line inclination part 18b3 is formed in a straight form in a manner to be inclined toward the sheet loading tray support groove 18b4 located below the first straight-line inclination part 18b3.
Moreover, the sheet loading tray support groove 18b4 is formed such that the rotational pin 16 (
In addition, the first horizontal straight-line part 18b5 is horizontally formed from a leading end of the sheet loading tray support groove 18b4.
Furthermore, the second horizontal straight-line part 18b6 is horizontally formed one step lower than the first horizontal straight-line part 18b5. As described below, when the sheet loading tray 11 reaches the sheet loading position, the lock pin 17 laterally provided on each of the right and left first brackets 14R and 14L can be saved above the second horizontal straight-line part 18b6.
Moreover, the second straight-line inclination part 18b7 is inclined downwardly from the second horizontal straight-line part 18b6 to be formed up to the other-end back part.
In addition, the lower part of each side of the other-end parts 18b of the right and left second brackets 18R and 18L protrudes more downwardly than the lower part of each side of the one-end parts 18a, and furthermore, the stopper pin 20 is laterally provided, inwardly, at a lower central inside of each side of the other-end parts 18b.
Then, the right and left second brackets 18R and 18L also use the same components to reduce the number of the components. However, the stopper pin 20 is laterally provided, inwardly, and thus the right and left second brackets 18R and 18L are fixed in a horizontally non-symmetrical manner on each inside surface of the right and left frame members 2R and 2L as illustrated in
Actions of the sheet loading device 10 according to the present invention configured as described above will be described by the use of
Note that, in
First,
Namely, a one-end part 14a of the left first bracket 14L is fixed to the side surface 11c of the sheet loading tray 11 by the use of two screws 15, and further, a one-end part 18a of the left second bracket 18L is fixed to the inside surface of the left frame member 2L vertically provided on the left side of the one side surface 2b of the casing 2 by the use of two screws 19.
In addition, the rotational pin 16 with leading end flange part laterally provided in the other-end part 14b of the left first bracket 14L is inserted from above to thereby rotatably fit into the sheet loading tray support groove 18b4 formed at the upper part of the side of the other-end part 18b of the left second bracket 18L.
Note that the leading end flange part formed on the rotational pin 16 is meshed with the upper part of the left second bracket 18L in the sheet loading tray support groove 18b4. With this arrangement, the rotational pin 16 is prevented from being horizontally pulled out.
Furthermore, the stopper pin 20 laterally provided in the lower central inside on the side of the other-end part 18b of the left second bracket 18L is engaged with the concave part 14e for engaging the stopper pin formed at a side facing the one side surface 2b of the casing 2 at the intermediate lower part 14d of the left first bracket 14L.
With this arrangement, since the sheet loading tray 11 is inclined up to an angle with which the sheet loading tray 11 is located slightly lower than the horizontal line with respect to the one side surface 2b of the casing 2 to thereby be supported at the sheet loading position, the sheet P can be loaded.
At this point, the lock pin 17 with leading end flange part laterally provided in the intermediate upper part 14c of the left first bracket 14L is saved above the second horizontal straight-line part 18b6 formed at the upper part of the side of the other-end part 18b of the left second bracket 18L.
Furthermore, when the sheet loading tray 11 reaches the sheet loading position, and when the sheet loading tray 11 is manually lifted and the rotational pin 16 laterally provided in the left first bracket 14L is pulled out from the sheet loading tray support groove 18b4 formed on the left second bracket 18L, the sheet loading tray 11 can be removed from the side of the one side surface 2b of the casing 2, with the sheet P loaded on the sheet loading tray 11.
Next,
Namely, in the second state, the sheet loading tray 11 is rotated counterclockwise about the rotational pin 16 fitted into the sheet loading tray support groove 18b4 formed on the left second bracket 18L, toward the side of the one side surface 2b of the casing 2 from the sheet loading position, and accordingly, the lock pin 17 laterally provided in the left first bracket 14L comes into contact with the curved cam part 18b2 formed on the upper part of the side of the other-end part 18b of the left second bracket 18L.
Then, when the lock pin 17 comes into contact with the curved cam part 18b2, a rotational center of the sheet loading tray 11 moves from the rotational pin 16 to the lock pin 17.
In addition, along with the counterclockwise rotation of the sheet loading tray 11, the stopper pin 20 laterally provided in the left second bracket 18L separates away from the concave part 14e for engaging the stopper pin formed on the left first bracket 14L.
Subsequently,
Namely, in the third state, a rotational center of the sheet loading tray 11 has moved from the rotational pin 16 to the lock pin 17. When the sheet loading tray 11 is further rotated in the counterclockwise direction, the lock pin 17 is moved to a side of a top point while sliding on the curved cam part 18b2 formed in the left second bracket 18L. Therefore, the rotational pin 16 fitted into the sheet loading tray support groove 18b4 formed in the left second bracket 18L comes off.
Next,
Namely, when the rotational pin 16 comes off from an inside of the sheet loading tray support groove 18b4 formed on the left second bracket 18L, the lock pin 17 enters the sheet loading tray lock groove 18b1 from the side of the top point of the curved cam part 18b2 formed on the left second bracket 18L to thereby be locked and held in the sheet loading tray lock groove 18b1.
Note that the leading end flange part formed on the lock pin 17 is meshed with the upper part of the left second bracket 18L in the sheet loading tray lock groove 18b1. With this arrangement, the lock pin 17 is prevented from horizontally coming off.
Between the sheet loading tray support groove 18b4 and the sheet loading tray lock groove 18b1, the left second bracket 18L is formed with the curved cam part 18b2 on which the lock pin 17 slides along with an action of rotating the sheet loading tray 11 toward the sheet loading tray storage position from the sheet loading position. Accordingly, the lock pin 17 slides on the curved cam part 18b2 formed on the left second bracket 18L, and thus can securely and smoothly enters the sheet loading tray lock groove 18b1 from the curved cam part 18b2. In addition, while the lock pin 17 slides the curved cam part 18b2, the rotational pin 16 comes off in the sheet loading tray support groove 18b4 and the sheet loading tray 11 is automatically lifted upward. Therefore, the lock pin 17 easily enters the sheet loading tray lock groove 18b1.
Furthermore, when the lock pin 17 enters the sheet loading tray lock groove 18b1, the rotational pin 16 does not come off, and is securely fitted into the sheet loading tray support groove 18b4 again. The sheet loading tray 11 reaches the sheet loading tray storage position in a state of being erected substantially vertically facing the side of the one side surface 2b of the casing 2.
According to the sheet loading device of the present invention described above in detail, when the sheet loading tray 11 loading the plurality of sheets P is rotatably and detachably configured between the sheet loading position and the sheet loading tray storage position on the side of the one side surface 2b of the casing 2 of the image forming apparatus 1, the rotational pin 16 and the lock pin 17 are laterally provided in the right and left first brackets 14R and 14L that are fixed to the right and left side surfaces 11d and 11c of the sheet loading tray 11 respectively, and furthermore, the right and left second brackets 18R and 18L are fixed to the right and left of the one side surfaces 2b of the casing 2. When the sheet loading tray 11 reaches the sheet loading position, the lock pin 17 is made to enter the sheet loading tray lock groove 18b1 formed on the right and left second brackets 18R and 18L to thereby lock and hold the sheet loading tray 11 at the sheet loading tray storage position, along with an action of rotating the sheet loading tray 11 about the rotational pin 16 fitting into the sheet loading tray support groove 18b4 formed on the right and left second brackets 18R and 18L from the sheet loading position to the sheet loading tray storage position.
As a result, it becomes unnecessary to provide a magnet for holding the sheet loading tray 11 in a state of being erected substantially vertically at the sheet loading tray storage position. Since components including a magnet, a magnet mounting plate, and a magnet adsorbing plate for holding the sheet loading tray 11 in the state of being erected substantially vertically at the sheet loading tray storage position are not necessary, the number of components constituting the entire sheet loading device can be reduced.
Furthermore, an unusual action during a series of actions for rotating the sheet loading tray 11 from the sheet loading position to the sheet loading tray storage position is not necessary. During a normal rotational action, the lock pin 17 laterally provided on the right and left first brackets 14R and 14L fixed to the right and left side surfaces 11d, 11c of the sheet loading tray 11 is made to enter the sheet loading tray lock groove 18b1 formed on the right and left second brackets 18R and 18L fixed to the right and left of the one side surface 2b of the casing 2. Thus, since the sheet loading tray 11 is securely locked and held while keeping a posture of being erected at the sheet loading tray storage position, the sheet loading tray 11 can be prevented from sudden falling, thereby not causing danger and not causing fear of breaking components.
Moreover, loading of the sheet loading tray 11 can be dispersed to four pins 16, 17 in the right and left at the sheet loading tray storage position, and can be received with the right and left second brackets 18R and 18L.
As described above, the present invention is not limited to the above described embodiment as it is, but the components can be modified and embodied within the scope not deviating from its gist in a practical stage. Further, by appropriate combination of plurality of components disclosed in the embodiment, various kinds of inventions can be formed. For example, some components may be deleted from all components described in the embodiment.
The present application claims the priority based on the Japanese Patent Application No. 2016-101075 filed on 20 May 2016, and all contents of the present application is incorporated into the present specification as reference.
