Description

[Technical field]

[0001] The present disclosure relates to image forming apparatuses such as copiers, multifunction machines, printers, and facsimile machines. [Background technology]

[0002] 2. Description of the Related Art Image forming apparatuses that include an image forming apparatus main body having a front and a side surface, and an opening / closing cover provided on a part of the side surface of the image forming apparatus main body so as to be openable and closable, are conventionally known.

[0003] 13A and 13B are perspective views showing a closed state and an open state of the opening / closing cover part 130X with respect to the image forming device main body 110X in a conventional image forming device 100X including the image forming device main body 110X and the opening / closing cover part 130X, respectively. Also, FIG. 14 is a perspective view showing the opening / closing cover part 130X in a half-open state in the conventional image forming device 100X shown in FIGS. 13A and 13B. In the drawings, the symbol X indicates the front-rear direction as seen from the front 110a, the symbol Y indicates the left-right direction Y perpendicular to the front-rear direction X, and the symbol Z indicates the up-down direction (vertical direction). This also applies to FIGS. 1A to 11B described later.

[0004] A conventional image forming device 100X includes an image forming device main body 110X having a front surface 110a and a side surface 110b, and an opening / closing cover portion 130X that is openably and closably provided on a portion of the side surface 110b (in this example, the side surface 110b on the right side as viewed from the front surface 110a) of the image forming device main body 110X.

[0005] The image forming apparatus main body 110X is provided with a locking portion (not shown), and the opening / closing cover portion 130X is provided with an operation portion 131X and an engagement portion (not shown). The operation portion 131X is operated when opening the opening / closing cover portion 130X relative to the image forming apparatus main body 110X. When the operation portion 131X is operated, the engagement portion in the opening / closing cover portion 130X is engaged with the locking portion in the image forming apparatus main body 110X in conjunction with the operation portion 131X, and the engagement with the locking portion is released.

[0006] In such an image forming device 100X, the operation unit 131X is often provided on the opening / closing cover portion 130X on the side surface 110b of the image forming device 100X when the image forming device 100X is viewed from the front surface 110a. In this case, it is difficult for a user to visually recognize the operation position of the operation unit 131X.

[0007] On the other hand, when performing an operation such as clearing a jammed sheet of recording paper or the like, after a user opens and closes the opening / closing cover section 130X, the opening / closing cover section 130X may not be securely closed (even if the opening / closing cover section 130X appears to be closed at first glance, the engagement section is not engaged with the locking section), i.e., the so-called half-door state (see Figure 14).

[0008] In this case, if a user mistakenly assumes that the opening / closing cover 130X is closed when it is in a half-open state and performs an image forming operation, a normal image forming operation cannot be performed due to inconveniences such as poor sheet conveyance. For this reason, the image forming device 100X is generally configured to prohibit an image forming operation when the opening / closing cover 130X is in a half-open state. In this case, a situation occurs in which a user cannot perform an image forming operation even though the opening / closing cover 130X appears to be closed (actually, the door is half-open), and therefore the user determines that the image forming device 100X is broken and calls an operator (serviceman). In this case, even though the image forming device 100X returns to normal simply by the user's operation of closing the opening / closing cover 130X, an unnecessary operator's work is required, such as the operator having to go to the installation location of the image forming device 100X of the user.

[0009] Therefore, it is desirable to allow a user to easily recognize whether the engagement portion on the opening / closing cover portion is engaged with the locking portion on the image forming apparatus main body or whether the engagement portion is not engaged with the locking portion and the door is left half-open.

[0010] In this regard, in a conventional configuration, the handle portion of each device has an identifying shape that can be identified by touch, such as a protrusion or depression, and the identifying shape of the handle is the same within each device but different between each device (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0011] [Patent Document 1] JP 2004-45941 A Summary of the Invention [Problem to be solved by the invention]

[0012] However, the configuration described in Patent Document 1 does not allow a user to easily recognize whether the engagement portion is engaged with the locking portion or whether the engagement portion is not engaged with the locking portion and the door is left half-open.

[0013] Therefore, the present disclosure aims to provide an image forming device that allows a user to easily recognize whether the engagement portion on the opening / closing cover portion is engaged with the locking portion on the image forming device main body or whether the engagement portion is not engaged with the locking portion and the opening / closing cover portion is in a half-open state. [Means for solving the problem]

[0014] In order to solve the above problem, the image forming apparatus disclosed herein comprises an image forming apparatus main body having a front and a side, and an opening / closing cover part that is openably and closably provided on a portion of the side of the image forming apparatus main body, wherein the image forming apparatus main body is provided with a locking part, and the opening / closing cover part is provided with an operation part that is operated when opening the opening / closing cover part from the image forming apparatus main body, and an engagement part that engages with the locking part in the image forming apparatus main body in conjunction with the operation part when the operation part is operated, and disengages from the locking part, and is characterized in that, when the image forming apparatus is viewed from the front, the operating position of the operation part is visible, making it possible to distinguish whether the engagement part is engaged with the locking part or the engagement part is disengaged from the locking part. Effect of the Invention

[0015] According to the present disclosure, it is possible for a user to easily recognize whether the engagement portion on the opening / closing cover portion is engaged with the locking portion on the image forming device main body or whether the engagement portion is not engaged with the locking portion and the opening / closing cover portion is in a half-open state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. The names and functions of the components are also the same. Therefore, detailed description thereof will not be repeated.

[0018] (Overall description of image forming apparatus) 1A, 1B, and 1C are respectively a perspective view, a front view, and a cross-sectional view showing an image forming apparatus 100 according to the present embodiment in a closed state with an opening / closing cover section 130. FIG.

[0019] As shown in Figures 1A to 1C, image forming apparatus 100 includes an image reading device 120 and an image forming apparatus main body 110, and forms a monochrome image or a color image on a sheet P such as recording paper by image forming apparatus main body 110 based on image data read by image reading device 120 or image data sent from an external device.

[0020] The image reading device 120 is mounted on the upper surface of the image forming apparatus main body 110. The image reading device 120 includes a document pressing unit 121 and a document reading device 122, and scans a scanning optical system 122b to read a document placed on a document placement table 122a with the document reading device 122, and outputs the image of the read document as image data.

[0021] The image forming apparatus 100 is an electrophotographic image forming apparatus, and is configured so as to have a plurality of image carriers (specifically, photosensitive drums 3) arranged side by side in a predetermined direction (in this example, the left-right direction Y), that is, a so-called tandem type color image forming apparatus. In this example, the image forming apparatus 100 is an intermediate transfer type color multifunction machine capable of forming full-color images. Note that, although the image forming apparatus 100 is a tandem type color image forming apparatus in this embodiment, it may be another type of color image forming apparatus. Also, although the image forming apparatus 100 is a color image forming apparatus, it may be a monochrome image forming apparatus.

[0022] As shown in FIG. 1C, the image forming section 160 in the image forming apparatus 100 includes a fixing device 1, a developing device 2, a photosensitive drum 3, a drum cleaning device 4, a charger 5, an intermediate transfer belt device 7, a secondary transfer device 11, an optical scanning device 12, and a paper feed section 18.

[0023] The image forming apparatus 100 handles image data corresponding to color images using the colors black (K), cyan (C), magenta (M), and yellow (Y), or monochrome images using a single color (e.g., black). The image forming apparatus 100 is provided with four developing devices 2, four photoconductor drums 3, four drum cleaning devices 4, and four chargers 5 for forming four types of toner images, and four image stations Pa, Pb, Pc, and Pd are configured corresponding to black, cyan, magenta, and yellow, respectively.

[0024] The optical scanning device 12 exposes the surface of the photoreceptor drum 3 to light to form an electrostatic latent image. The developing device 2 develops the electrostatic latent image on the surface of the photoreceptor drum 3 to form a toner image on the surface of the photoreceptor drum 3. The drum cleaning device 4 removes and collects residual toner on the surface of the photoreceptor drum 3. The charger 5 uniformly charges the surface of the photoreceptor drum 3 to a predetermined potential. Through the series of operations described above, a toner image of each color is formed on the surface of each photoreceptor drum 3.

[0025] The intermediate transfer belt device 7 includes an intermediate transfer roller 6, an endless intermediate transfer belt 71, an intermediate transfer driving roller 72, an intermediate transfer driven roller 73, and a cleaning device 9. Four intermediate transfer rollers 6 are provided inside the intermediate transfer belt 71 so as to form four types of toner images corresponding to the respective colors. The intermediate transfer rollers 6 transfer the toner images of the respective colors formed on the surfaces of the photosensitive drums 3 onto the intermediate transfer belt 71 which moves in a circulating manner.

[0026] The intermediate transfer belt 71 is stretched around an intermediate transfer drive roller 72 and an intermediate transfer driven roller 73. In the image forming apparatus 100, the toner images of each color formed on the surface of each photoconductor drum 3 are sequentially transferred and superimposed to form a color toner image on the surface of the intermediate transfer belt 71. The cleaning device 9 removes and collects waste toner remaining on the surface of the intermediate transfer belt 71 without being transferred to the sheet P.

[0027] The secondary transfer device 11 sandwiches and transports a sheet P, which has been transported through a sheet transport path 21, in a transfer nip portion TN between the secondary transfer roller 11a and the intermediate transfer belt 71. When the sheet P passes through the transfer nip portion TN, the toner image on the surface of the intermediate transfer belt 71 is transferred to the sheet P, and the sheet P is transported to the fixing device 1.

[0028] The fixing device 1 includes a fixing belt 31 that rotates around an axis and a pressure roller 32. The fixing device 1 sandwiches the sheet P, onto which the toner image has been transferred, in a fixing nip portion FN between the fixing belt 31 and the pressure roller 32, and applies heat and pressure to fix the toner image onto the sheet P.

[0029] The paper feed section 18 includes a paper feed cassette for stacking sheets P used for image formation, and is provided below the optical scanning device 12. The sheet P is pulled out of the paper feed section 18 by a pickup roller 16 and conveyed to a sheet conveying path 21. The sheet P conveyed to the sheet conveying path 21 passes through the secondary transfer device 11 and the fixing device 1, and is discharged to a discharge tray 19 by a discharge roller 17.

[0030] A sheet conveying roller 13, a registration roller 14, and a discharge roller 17 are arranged in the sheet conveying path 21. The sheet conveying roller 13 promotes the conveyance of the sheet P. The registration roller 14 temporarily stops the sheet P conveyed from the paper feed unit 18 in a sandwiched state, and starts conveying the sheet P at a constant speed in synchronization with the secondary transfer device 11.

[0031] When an image is formed on the back side of the sheet P in addition to the front side, the conveying direction of the sheet P is changed by the discharge rollers 17, and the sheet P is conveyed to a reversing sheet conveying path 22. In the reversing sheet conveying path 22, the sheet P is guided to the registration rollers 14 in a state in which the sheet P is reversed by the reversing sheet conveying rollers 15. The image forming apparatus 100 forms an image on the back side of the sheet P guided to the registration rollers 14 in the same manner as on the front side, and discharges the sheet P to the discharge tray 19.

[0032] (First embodiment) In this embodiment, the image forming apparatus 100 includes an image forming apparatus main body 110 having a front surface 110a and a side surface 110b perpendicular to the front surface 110a, and an opening / closing cover section 130 provided on a part of the side surface 110b of the image forming apparatus main body 110 so as to be openable and closable. In this example, the image forming apparatus main body 110 has both side surfaces 110b and 110c perpendicular to the front surface 110a, and a back surface 110d that is deeper than the front surface 110a and parallel to the front surface 110a, and the opening / closing cover section 130 is provided on at least one side of the both side surfaces 110b and 110c (in this example, the side surface 110b on the right side as viewed from the front). Here, the "front surface 110a of the image forming apparatus 100" refers to the surface (front surface) on the side (front side) where the user operates the image forming apparatus 100.

[0033] In this example, the opening / closing cover portion 130 is provided on a part of the side surface 110b of the image forming apparatus main body 110 so as to be freely movable in the left-right direction Y, and when in a closed, obstructed state, a part of it forms a sheet transport path (in this example, a sheet transport path 22 for reversal (see Figure 1C)) for transporting a sheet P during image formation.

[0034] 2A and 2B are a perspective view and a front view, respectively, showing an open state of opening / closing cover section 130 in image forming apparatus 100 according to the present embodiment.

[0035] The opening / closing cover 130 is supported by the image forming apparatus main body 110 by a pair of slide members 140, 140 arranged along the left-right direction Y.

[0036] In detail, the pair of slide members 140, 140 have their fixed portions fixed to the front surface 110a side X1 and the rear surface 110d side X2 at the lower side in the up-down direction Z of the image forming apparatus main body 110, and their movable portions fixed to the front surface 110a side X1 and the rear surface 110d side X2 of the lower part of the opening-closing cover part 130. This allows the opening-closing cover part 130 to reciprocate in the left-right direction Y relative to the image forming apparatus main body 110.

[0037] 3A and 3B are respectively a perspective view and a front view showing a half-open state of the opening / closing cover unit 130 in the image forming apparatus 100 according to the present embodiment. Fig. 4A and Fig. 4B are respectively enlarged front views showing the frame α1 portion shown in Fig. 1B and the frame α2 portion shown in Fig. 3B.

[0038] 5A and 5B are perspective views showing one engaging portion 132 provided on the front surface 110a side X1 of the opening / closing cover portion 130 and the other engaging portion 132 provided on the rear surface 110d side X2 of the opening / closing cover portion 130. Figures 6A and 6B are perspective views of the pair of engaging portions 132, 132 as viewed from the front surface 110a side X1 and the rear surface 110d side X2, respectively.

[0039] 7A to 7C are perspective views showing an engaged state, a disengaged state, and an intermediate state of the engaging portion 132 with the locking portion 111, respectively. Also, Figs. 8A to 8C are cross-sectional views showing an engaged state, a disengaged state, and an intermediate state of the engaging portion 132 with the locking portion 111, respectively. Note that Figs. 7A to 8C show the configuration of one side (front surface 110a side X1) in the front-rear direction X, but the configuration of the other side (rear surface 110d side X2) is similar, and so here only the configuration of one side (X1) is shown as a representative.

[0040] The image forming apparatus main body 110 is provided with a locking portion 111 (see FIGS. 7A to 8C), and the opening / closing cover portion 130 (see FIGS. 5A and 5B) is provided with an operation portion 131 and an engagement portion 132 (see FIGS. 6A and 6B). The operation portion 131 is operated when opening the opening / closing cover portion 130 from the image forming apparatus main body 110. The engagement portion 132 in the opening / closing cover portion 130 is capable of engaging with the locking portion 111 in the image forming apparatus main body 110 in conjunction with the operation portion 131 when the operation portion 131 is operated by a user, and is capable of disengaging from the locking portion 111 (see FIGS. 7A to 8C).

[0041] When the opening / closing cover unit 130 is in a closed state (see FIGS. 1A, 1B, and 4A) in which it is closed relative to the image forming apparatus main body 110, the operation unit 131 is located at a first operation position. When the user performs a disengagement operation on the operation unit 131 to release the engagement of the engagement unit 132 with the locking unit 111 in the image forming apparatus main body 110, the operation unit 131 is located at a second operation position and is maintained at the second operation position (see FIGS. 2A and 2B). At this time, the user performs an opening operation on the opening / closing cover unit 130, so that the opening / closing cover unit 130 can be brought into an open state (see FIGS. 2A and 2B) in which it is open relative to the image forming apparatus main body 110. On the other hand, when the user performs a closing operation on the opening / closing cover unit 130 to bring the opening / closing cover unit 130 into a closed state, the engagement unit 132 is engaged with the locking unit 111, so that the operation unit 131 can be returned to the first operation position.

[0042] The operating part 131 and the engaging part 132 are provided to be rotatable about a rotation axis β along the front-rear direction X with respect to the opening-closing cover part main body 130a. The operating part 131 rotates together with the engaging part 132 about the rotation axis β when operated by a user.

[0043] In detail, the opening / closing cover part 130 includes an operating lever part 139 (see Figs. 5A to 8C). The operating lever part 139 includes an operating part 131, a pair of engaging parts 132, 132, a rotating shaft 133, and a biasing member 134 (a kick spring in this example) (see Figs. 5B, 6A, and 6B).

[0044] The rotating shaft 133 is supported rotatably around a rotation axis β with respect to the opening / closing cover main body 130a (see Figs. 5A and 5B). The operating part 131 is connected to the engaging part 132 on the front surface 110a side X1 of the pair of engaging parts 132, 132. One end of the biasing member 134 is engaged with the opening / closing cover main body 130a and the other end is engaged with the engaging part 132 so as to bias the engaging part 132 in a first rotation direction R1 with the circular part inserted into the rotating shaft 133. Here, the first rotation direction R1 is the rotation direction of the engaging part 132 to the non-engagement side in the rotation direction R about the rotation axis β.

[0045] Rotary shaft support parts 135, 135 (see FIGS. 5A and 5B) are provided on the front surface 110a side X1 and the rear surface 110d side X2 of the opening / closing cover part main body 130a to protrude toward the image forming apparatus main body 110. The rotary shaft support parts 135, 135 are provided with through holes 135a, 135a along the front-rear direction X. The rotary shaft 133 is inserted through the through holes 135a, 135a in the rotary shaft support parts 135, 135 to be rotatable around a rotation axis β.

[0046] The movement of the rotating shaft 133 in the front-rear direction X with respect to the opening-closing cover main body 130a is restricted by stop members 136-136 (E-rings in this example) provided on the rotating shaft 133.

[0047] The operation unit 131 is provided with a through hole 131d (see FIGS. 7A to 7C) along the front-rear direction X. The through hole 131d of the operation unit 131 is inserted through the rotating shaft 133 on the outer side of the rotating shaft support portion 135 (see FIG. 5A) on the front surface 110a side X1.

[0048] The pair of engaging portions 132, 132 are provided with through holes 132c (see FIGS. 8A to 8C) along the front-rear direction X. The through hole 131d of the engaging portion 132 on the front surface 110a side X1 is inserted through the rotating shaft 133 outside the operating portion 131. The through hole 131d of the engaging portion 132 on the rear surface 110d side X2 is inserted through the rotating shaft 133 outside the rotating shaft support portion 135 (see FIG. 5B) on the rear surface 110d side X2.

[0049] The engagement portion 132 on the front surface 110a side X1 is provided with a first restricting portion 132a and a second restricting portion 132b (see Fig. 6A, Fig. 8A to Fig. 8C). The first restricting portion 132a abuts against the first restricted portion 131a (see Fig. 6A, Fig. 8A to Fig. 8C) of the operation portion 131 to restrict the rotational movement of the operation portion 131 in the first rotational direction R1. The second restricting portion 132b abuts against the second restricted portion 131b of the operation portion 131 to restrict the rotational movement of the operation portion 131 in the second rotational direction R2. Here, the second rotational direction R2 is the rotational direction of the engagement portion 132 toward the engagement side in the rotational direction R about the rotation axis β. The pair of engagement portions 132, 132 are fixed to both ends of the rotation shaft 133 in the front-rear direction X by fixing members SC, SC such as screws (see Figs. 5A to 6B, Figs. 8A to 8C). This allows the operating lever portion 139 (operating portion 131 and engaging portion 132) to rotate around the rotation axis β between a first operating position of the operating portion 131, where the engaging portion 132 is located at a predetermined engagement position where it engages with the locking portion 111, and a second operating position of the operating portion 131, where the engaging portion 132 is located at a disengagement position where the locking portion 111 is released.

[0050] The opening / closing cover main body 130a is provided with a restricting portion 130a1 (see FIGS. 8A to 8C) that restricts excessive rotation of the operating portion 131 and the pair of engaging portions 132, 132 in the first rotation direction R1. As a result, the restricting portion 130a1 can abut against the third restricted portion 131c of the operating portion 131 to position the engaging portion 132 at the disengagement position, thereby maintaining the operating portion 131 at the second operating position.

[0051] The locking portion 111 is fixed at a predetermined position of the image forming apparatus main body 110. The engagement portion 132 in the opening / closing cover main body 130a has a protrusion 132d and a recess 132e. The protrusion 132d is provided on the tip side of the main body 1321 extending in a radial direction perpendicular to the front-rear direction X, and protrudes from the main body 1321 in the second rotation direction R2. The recess 132e is provided adjacent to the protrusion 132d between the protrusion 132d of the main body 1321 and the rotation shaft 133. The protrusion 132d has an inclined surface 132f that is inclined so as to become lower in the second rotation direction R2 as it moves away from the base end side of the engagement portion 132 to the tip side. The recess 132e has a first wall surface 132g on the protrusion 132d side, a second wall surface 132h on the rotation shaft 133 side, and an abutment portion 132j ​​that forms a corner between the second wall surface 132h and the top surface 132i. When the engagement portion 132 is in a disengaged state (located at the disengaged position) (see FIG. 8B), the abutment portion 132j ​​is located on the locking portion 111 side of the rotation axis β in the left-right direction Y and above the rotation axis β in the up-down direction Z.

[0052] The locking portion 111 is provided with a locking surface 111a (see FIGS. 7A to 8C) that locks the engaging portion 132 (first wall surface 132g in this example), and a contacted portion 111b (see FIGS. 7A to 8C) that contacts the contact portion 132j ​​on the outer surface opposite to the locking surface 111a in the left-right direction Y. The locking surface 111a is inclined upward [so as to approach the operating portion 131 side as it moves from the lower side (the main body portion 1321 side of the engaging portion 132) to the upper side]. In addition, in the closed state, the opening / closing cover portion 130 is biased in a direction (Y1) away from the image forming apparatus main body 110 in the left-right direction Y by a biasing force of a biasing member such as a spring provided on the sheet conveying roller 15 in the sheet conveying path 22 (see FIG. 1C).

[0053] In the configuration described above, when the opening / closing cover section 130 is in the closed state, the engaging section 132 is engaged with the locking section 111 and the operating section 131 is located at the first operating position (see FIG. 8A). At this time, when the user operates the operating section 131 and rotates the operating section 131 in the first rotation direction R1, the engaging section 132 is disengaged from the locking section 111 and the engaging section 132 is located at the disengaged position. At this time, the operating section 131 is maintained at the second operating position. Next, when the user opens the opening / closing cover section 130 with respect to the image forming apparatus main body 110 [pulling it out to one side in the left-right direction Y (the right side Y1 in this example)], the opening / closing cover section 130 is in the open state with respect to the image forming apparatus main body 110. This allows the user to perform an operation such as removing a jammed sheet P.

[0054] On the other hand, when the user operates the opening / closing cover unit 130 to close (pushes it by hand), the opening / closing cover unit 130 moves to the other side in the left-right direction Y (left side Y2 in this example) relative to the image forming apparatus main body 110, and the opening / closing cover unit 130 closes. At this time, as shown in FIG. 8B, the abutting portion 132j ​​of the engaging portion 132 abuts against the abutted portion 111b of the locking portion 111, and when the opening / closing cover unit 130 further moves to the other side in the left-right direction Y (left side Y2 in this example), the engaging portion 132 rotates in a second rotation direction R2 around the rotation axis β. Then, the first wall surface 132g of the engaging portion 132 faces the locking surface 111a of the locking portion 111. Next, when the user releases the closing operation of the opening / closing cover part 130 (when the hand is released), the opening / closing cover part 130 biased to the right side Y1 in the left-right direction Y moves to the right side Y1 with respect to the image forming apparatus main body 110, and the first wall surface 132g abuts against the locking surface 111a inclined upward. This allows the engaging part 132 to engage with the locking part 111, and thus the opening / closing cover part 130 in the closed state can be locked with respect to the image forming apparatus main body 110. At this time, the upward inclination of the locking surface 111a that engages the engaging part 132 can prevent rotational movement in the first rotation direction R1 due to the biasing force of the biasing member 134. This allows the engaging part 132 to be maintained in the engaging position, that is, the operating part 131 to be maintained in the first operating position.

[0055] However, if a user mistakenly believes that opening / closing cover section 130 is closed when it is in a half-open state and performs an image forming operation, normal image forming operation cannot be performed due to inconveniences such as poor conveyance of sheet P. Here, the "half-open state" refers to a state in which opening / closing cover section 130 is not securely closed after the user performs an opening / closing operation of opening / closing cover section 130 (a state in which engaging section 132 is not engaged with locking section 111 even if opening / closing cover section 130 appears to be closed at first glance). The half-open state is included in the open state.

[0056] For this reason, image forming apparatus 100 is configured to prohibit image forming operations when opening / closing cover section 130 is in a half-open state. This causes a situation in which a user cannot perform image forming operations even though opening / closing cover section 130 appears to be closed (when in fact the door is half-open), and so determines that image forming apparatus 100 is broken and calls an operator (serviceman). In this case, even though image forming apparatus 100 can be restored to normal simply by the user's operation of closing opening / closing cover section 130, the operator must go to the location where image forming apparatus 100 is installed, which results in unnecessary work for the operator.

[0057] In this regard, in the present embodiment, when the image forming apparatus 100 is viewed from the front 110a, the operating position of the operating unit 131 is visible, which enables one to distinguish whether the engaging portion 132 is engaged with the locking portion 111 or whether the engaging portion 132 is disengaged from the locking portion 111 (whether the door is in a half-open state) (see Figures 1B, 2B, 3B, 4A, and 4B).

[0058] Here, the position of the user when "viewing image forming device 100 from front 110a" is a user of standard height (e.g., approximately 150 cm to 185 cm) standing facing front 110a of image forming device main body 110, at the end position of front 110a of image forming device main body 110 on the opening / closing cover section 130 side, or at a position within a predetermined distance (e.g., approximately 1 m) rearward from the end position.

[0059] According to this embodiment, when viewed from the front 110a, the image forming apparatus 100 allows a user to visually recognize the operating position of the operating unit 131, which enables the user to distinguish whether the engagement portion 132 has been disengaged from the locking portion 111 (whether the door is in a half-open state). This allows the user to easily recognize whether the engagement portion 132 in the opening / closing cover portion 130 is engaged with the locking portion 111 in the image forming apparatus main body 110, or whether the engagement portion 132 is not engaged with the locking portion 111 and the opening / closing cover portion 130 is in a half-open state.

[0060] Second embodiment In this embodiment, the operation unit 131 is rotatable about a rotation axis β along the front-rear direction X when viewed from the front surface 110a.

[0061] In this configuration, since the operation unit 131 is rotatable around the rotation axis β, it is easy to realize a configuration in which the operation position of the operation unit 131 can be visually confirmed when the image forming apparatus 100 is viewed from the front 110a.

[0062] Third embodiment However, if the operating position of the operating part 131 when the engagement part 132 is engaged with the locking part 111 is the same as the operating position of the operating part 131 when the engagement part 132 is disengaged from the locking part 111, it is difficult for the user to recognize that the opening / closing cover part 130 is in a half-door state due to the operating position of the operating part 131.

[0063] In this regard, in the present embodiment, the operation unit 131 is located at a first operation position (see Figs. 1B and 4A) when the engagement unit 132 is engaged with the locking unit 111, and is located at a second operation position (see Figs. 3B and 4B) different from the first operation position when the engagement unit 132 is disengaged from the locking unit 111. In this example, the operation unit 131 is rectangular. The rectangular operation unit 131 in the first operation position is aligned along the up-down direction Z, and the rectangular operation unit 131 in the second operation position is inclined with respect to the up-down direction Z so that the upper side is located on the side of the engagement unit 132 and the lower side is located opposite to the engagement unit 132 in the left-right direction Y.

[0064] In this configuration, the operating unit 131 is located in a first operating position when the engaging portion 132 is engaged with the locking portion 111, and is located in a second operating position when the engaging portion 132 is disengaged from the locking portion 111, thereby allowing the user to easily and clearly recognize that the opening / closing cover portion 130 is in a half-open state depending on the operating position of the operating unit 131.

[0065] (Fourth embodiment) Figures 9A and 9B are respectively an enlarged perspective view and a bottom view of the operation unit 131 shown in Figure 1A, and Figures 10A and 10B are respectively an enlarged perspective view and a bottom view of the operation unit 131 shown in Figure 3A.

[0066] In this embodiment, operation unit 131 has a shape (polyhedral shape in this example) having straight sides 1311, 1312. When image forming apparatus 100 is viewed from front 110a, when operation unit 131 is located at a first operation position (see FIGS. 1B, 4A, and 9A), straight sides 1311, 1312 of operation unit 131 are aligned along the vertical direction Z (see FIG. 9A), and when operation unit 131 is located at a second operation position (see FIGS. 3B, 4B, and 10A), straight sides 1311, 1312 of operation unit 131 are inclined with respect to the vertical direction Z (see FIG. 10A).

[0067] In this configuration, when the operating unit 131 is located at the first operating position, the straight sides 1311, 1312 of the operating unit 131 are aligned along the vertical direction Z, and when the operating unit 131 is located at the second operating position, the straight sides 1311, 1312 of the operating unit 131 are inclined with respect to the vertical direction Z, thereby allowing the user to more clearly recognize that the opening / closing cover unit 130 is in a half-open state.

[0068] Fifth embodiment Incidentally, when image forming apparatus 100 is installed in a location with limited installation space, such as a convenience store, it is difficult to apply force when closing opening / closing cover portion 130 onto image forming apparatus main body 110, and it may not be possible to close opening / closing cover portion 130 and reliably bring engagement portion 132 into engagement with locking portion 111 (locked state).

[0069] In this regard, in the present embodiment, the locking portion 111 in the image forming apparatus main body 110 and the engaging portion 132 in the opening / closing cover portion 130 are configured so that the engaging portion 132 engages with the locking portion 111 by performing an operation on the operating portion 131 to return it from the second operating position to the first operating position when the opening / closing cover portion 130 is in a predetermined position relative to the image forming apparatus main body 110 (e.g., the door is half-open).

[0070] In this example, the predetermined position of the opening / closing cover part 130 is a position in which, when the operating part 131 is located in the second operating position, as shown in FIG. 8B, i.e., when the engagement part 132 is inclined so as to be lower on the locking part 111 side than the rotation axis β, the lower end part 111a1 of the locking surface 111 of the locking part 111 is between the upper end part 132g1 and the lower end part 132g2 of the first wall surface 132g in the left-right direction Y.

[0071] When the user operates the operation unit 131 from a predetermined position of the opening / closing cover unit 130 to move it toward the first operation position, and the operation unit 131 and the engagement unit 132 rotate in the second rotation direction R2, as shown in Fig. 8C, the first wall surface 132g of the engagement unit 132 abuts against the lower end 111a1 of the locking surface 111a of the locking unit 111. When the user further operates the operation unit 131 and the operation unit 131 and the engagement unit 132 further rotate in the second rotation direction R2, the first wall surface 132g slides against the locking surface 111a while the engagement unit 132 moves to the other side in the left-right direction Y (the left side Y2 in this example), and thus the opening / closing cover unit 130 moves to the other side (Y2) in the left-right direction Y relative to the image forming apparatus main body 110. When the user further operates the operating portion 131 and the operating portion 131 and the engaging portion 132 further rotate in the second rotation direction R2, the engaging portion 132 engages with the locking portion 111, and the opening / closing cover portion 130 becomes closed, as shown in FIG. 8A.

[0072] In this configuration, when a user operates operating unit 131 to return from the second operating position to the first operating position with opening / closing cover unit 130 in a predetermined position (half-open state), the engagement portion engages with the locking portion and opening / closing cover unit 130 becomes closed, so that even if image forming apparatus 100 is installed in a facility with limited installation space, such as a convenience store, opening / closing cover unit 130 can be closed and engagement portion 132 can be securely engaged (locked) with locking portion 111.

[0073] Sixth embodiment 9A to 10B, in this embodiment, a first inclined surface 130b is provided on the front surface 110a side of the exterior cover member 1301 in the opening / closing cover section 130, the first inclined surface 130b being inclined so as to move away from the image forming apparatus main body 110 as it moves from the front surface 110a side to the rear surface 110d side of the image forming apparatus main body 110. The first inclined surface 130b is inclined in a cross direction S (inclined direction) that crosses both the front-rear direction X and the left-right direction Y.

[0074] A recess 130d (see FIG. 10A) is provided on the first inclined surface 130b. The operation portion 131 is provided in the recess 130d on the first inclined surface 130b.

[0075] Specifically, the first inclined surface 130b extends along the vertical direction Z on the front surface 110a side of the exterior cover member 1301 of the opening / closing cover main body 130a. A recess 130d is formed in the first inclined surface 130b, and an opening 130c is formed at a corner portion between the bottom surface and the top surface of the recess 130d. The operation unit 131 faces the outside from the inside of the opening / closing cover main body 130a through the opening 130c. The recess 130d has two linear edges 130d1 and 130d2 along the vertical direction Z and two linear edges 130d3 and 130d4 along the intersecting direction S. When the operation unit 131 is located at the first operation position, the side 1312 on the front surface 110a side of the operation unit 131 is parallel to and close to the edge 130d2 on the front surface 110a side of the recess 130d. When the operating portion 131 is located at the second operating position, a side 1312 of the operating portion 131 on the front surface 110a side intersects with an edge 130d2 of the recessed portion 130d on the front surface 110a side.

[0076] The first inclination angle θ1 (see FIG. 9B) of the first inclined surface 130b with respect to the imaginary plane γ along the front surface 110a can be, for example, about 40 degrees to 70 degrees, and in this example, the first inclination angle θ1 is set to 60 degrees.

[0077] In this configuration, the operation unit 131 is provided in the recessed portion 130d in the first inclined surface 130b, which allows the user to more easily visually recognize the operation position of the operation unit 131. This allows the user to more easily recognize that the opening / closing cover portion 130 is in a half-open state.

[0078] Seventh embodiment In this embodiment, the operation unit 131 is provided with a first plane 131e, a second inclined surface 131f, and a second plane 131g. When the operation unit 131 is located at the first operation position, the first plane 131e is a surface along the side surface 110b of the image forming device main body 110, the second inclined surface 131f is a surface that inclines so as to move away from the image forming device main body 110 as it moves from the front surface 110a side to the rear surface 110d side of the image forming device main body 110, and the second plane 131g is a surface along the front surface 110a of the image forming device main body 110. In this example, the second inclined surface 131f is formed so as to follow the first inclined surface 130b of the exterior cover member 1301 when the operation unit 131 is located at the first operation position. Of the two straight sides 1311, 1312 of the operating unit 131, one side 1311 is composed of a first plane 131e and a second inclined surface 131f, and the other side 1312 is composed of the second inclined surface 131f and a second plane 131g.

[0079] The second inclination angle θ2 (see FIG. 10B) of the second inclined surface 131f with respect to the virtual plane γ along the front surface 110a can be set to the same angle as that of the first inclined surface 130b, and can be, for example, approximately 40 degrees to 70 degrees. In this example, the second inclination angle θ2 is set to 60 degrees.

[0080] In this configuration, the operation unit 131 is provided with a second inclined surface 131f that inclines from the front surface 110a toward the rear surface 110d so as to move away from the image forming apparatus main body 110 when the operation unit 131 is located at the first operation position, thereby increasing the area through which the user can view the operation unit 131, and therefore making it easier for the user to view the operation position of the operation unit 131. This allows the user to more easily recognize that the opening / closing cover unit 130 is in a half-open state.

[0081] Eighth embodiment In this embodiment, a first index M1 (a first indication label in this example) and a second index M2 (a second indication label in this example) are provided on the first inclined surface 130b and the second inclined surface 131f, respectively.

[0082] The first index M1 and the second index M2 face each other (aligned in the front-to-back direction X) when the operating unit 131 is located at the first operating position (see FIG. 9A), and do not face each other (shifted in the front-to-back direction X) when the operating unit 131 is located at the second operating position (see FIG. 10A).

[0083] This allows the user to more easily visually recognize the operation position of operation unit 131. This allows the user to more easily recognize that opening / closing cover unit 130 is in a half-open state.

[0084] In this example, the first index M1 and the second index M2 are both triangular, with one vertex close to each other when the operation unit 131 is located at the first operation position, and one vertex separated from each other when the operation unit 131 is located at the second operation position. This allows the user to more easily recognize that the opening / closing cover unit 130 is in a half-open state.

[0085] Ninth embodiment 11A and 11B are perspective views, viewed from above on the rear surface 110d side, showing detection states of the detection unit 137 when the engagement unit 132 is engaged with and disengaged from the locking unit 111. Also, Fig. 12 is a block diagram showing a system configuration of the control unit 150, the image forming unit 160, the detection unit 137, and the display unit 170 in the image forming apparatus 100.

[0086] The image forming apparatus 100 further includes a control unit 150 , an image forming unit 160 , a detection unit 137 , a display unit 170 , and a detected member 112 .

[0087] 12, the control unit 150 has a processing unit 151 and a storage unit 152. The processing unit 151 is composed of a microcomputer such as a CPU. The storage unit 152 includes a non-volatile memory such as a ROM and a volatile memory such as a RAM. The control unit 150 controls the operation of various components by the processing unit 151 loading a control program stored in advance in the ROM of the storage unit 152 onto the RAM of the storage unit 152 and executing it.

[0088] The image forming section 160 performs an image forming operation to form an image on the sheet P. The detection section 137 detects whether or not the engagement section 132 of the opening / closing cover section 130 is engaged with the locking section 111 of the image forming apparatus main body 110 at a predetermined engagement position. The detection section 137 is electrically connected to an input system of the control section 150. This enables the detection section 137 to transmit a detection signal indicating whether or not the engagement section 132 is engaged with the locking section at the predetermined engagement position to the control section 150. The display section 170 displays various information on a display screen based on display data.

[0089] In this example, the detection unit 137 is a switch (so-called microswitch) having an actuator unit 137a. The detection unit 137 is fixed to the image forming apparatus main body 110 so that the actuator unit 137a faces downward, and is turned on and off by the actuator unit 137a swinging about a swing axis along the left-right direction Y.

[0090] The detected member 112 is fixed to the image forming apparatus main body 110, and has a detected member main body 112a and a detected portion 112b supported by the detected member main body 112a so as to be able to swing. The detected portion 112b is configured to be able to swing between a first position and a second position. The first position is a position (pressing position) where the detected portion 112b abuts against the engaging portion 132 and moves upward when the engaging portion 132 is located at the engaging position, so that the detected portion 112b presses the actuator portion 137a in the detecting portion 137 upward. The second position is a position (pressing release position) where the detected portion 112b releases its abutment against the engaging portion 132 and moves downward when the engaging portion 132 is located at the disengaging position, so that the pressure of the detected portion 112b against the actuator portion 137a in the detecting portion 137 is released. The detected member main body 112a and the detected portion 112b are integrally formed. The detected part 112b is made of a flexible material (resin material), and is configured to be located at the pressure release position by its own weight and / or a downward biasing force when no external force is applied. When the detected part 112b abuts against the engaging part 132, it swings to the upper first position against its own weight and / or the downward biasing force. At this time, the detecting part 137 is turned on. Furthermore, when the detected part 112b is released from the abutment with the engaging part 132, it returns to the lower second position by the downward biasing force. At this time, the detecting part 137 is turned off.

[0091] In this embodiment, the control unit 150 is configured to prohibit the image forming operation of the image forming unit 160 when it detects that the engagement unit 132 is not engaged with the locking unit 111 based on the detection result of the detection unit 137. Furthermore, when the control unit 150 detects that the engagement unit 132 is not engaged with the locking unit at the engagement position (open state, half-open state) based on the detection result of the detection unit 137, it issues an instruction to close the opening / closing cover unit 130. In this example, the control unit 150 displays a message to close the opening / closing cover unit 130 (for example, a message such as "The opening / closing cover unit is open. Please close the opening / closing cover unit.") on the display unit 170. Note that the control unit 150 may be configured to issue an alert by voice instead of or in addition to displaying the message.

[0092] As in the present embodiment, even if the user opens and closes the opening and closing cover section 130 to remove a jammed sheet P or the like, and the opening and closing cover section 130 is left half-open (see Figs. 3B and 4B), and the image forming operation of the image forming section 160 is prohibited, the user can clearly recognize that the opening and closing cover section 130 is not securely closed due to the operating position of the operating section 131, and is left half-open. This effectively prevents a situation in which a worker (serviceman) needs to be called, and ultimately avoids unnecessary work by the worker, such as the worker having to go to the location where the user's image forming apparatus 100 is installed.

[0093] The present disclosure is not limited to the above-described embodiments, and can be implemented in various other forms. Therefore, the embodiments are merely illustrative in all respects and should not be interpreted as being limited. The scope of the present disclosure is indicated by the claims, and is not restricted in any way by the text of the specification. Furthermore, all modifications and changes within the scope of the claims are within the scope of the present disclosure. [Explanation of symbols]
