DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus such as a copying machine, and more particularly, to an image forming apparatus having an automatic document traveling device for automatically transporting a document, in which document and paper are supplied and ejected in the same direction, and on the operating side of an operator. The present invention relates to an image forming apparatus performed in the above.

[0002]

2. Description of the Related Art Conventionally, a copying machine as an image forming apparatus has been disclosed in Japanese Patent Publication No. 59-9046, for example, in which an operator operates a left or right side of an operating unit in front of the copying machine. There are many types in which a manuscript or copy paper is set, and after the copy is completed, the manuscript or copy paper is discharged from the right or left side of the copier.

However, in such a copying machine, the size becomes large in the left-right direction when viewed from the operation surface side, so that a large installation space for the apparatus is required. , The operation related to copying of the copying machine by the operator becomes complicated.

Japanese Patent Laid-Open Publication No. 51-111332 discloses a configuration in which a document is input from the operation unit side of a copying machine and the document is output to the operation unit side. Therefore,
Original input / output is in the same direction as the copier operation direction, so operability is improved compared to when the original and paper setting direction and discharge direction are separated left and right with respect to the copier operation unit. I do.

However, in the copying machine disclosed in the above publication, since the input / output direction of the copy paper is the left / right direction with respect to the operation unit on the front of the copy machine, the input / output direction of the original and the input / output direction of the copy paper are different. Are orthogonal to each other. As described above, if the document and the paper are set apart from each other, in a case where the paper size is switched for each of a small number of documents and copying is performed, the movement of the hand of the operator becomes complicated, and the operability is reduced. Is decreasing.

For example, Japanese Patent Publication No. 45-36800 discloses a "photoelectrostatic copying machine" in which input / output of a document and input / output of a copy sheet are performed by an operator of the copying machine. ing. Further, Japanese Utility Model Laid-Open No. 55-6986 discloses a "copying machine built-in disk" in which at least a document placing surface or a document insertion port and an operation section of the copying machine are exposed during copying.

In the above two publications, the operator can input and output the original and the copy paper on the same side of the copying machine, so that the input and output directions of the original and the copy paper are orthogonal. The operability can be improved as compared with the case of performing.

[0008]

However, the copying machines disclosed in the above publications can input and output documents and paper in front of the operator in any case. Since the input / output unit and the paper input / output unit are arranged separately to the left or right toward the operator, there is a problem that the apparatus becomes extremely large in the left-right direction with respect to the operation unit. I have.

The copying machines disclosed in the above publications perform input and output of originals and paper from the operation unit side.
Documents and paper are fed in and out from the front end of the main unit, so the space used for input and output of the original and paper must be secured separately from the installation area of the main unit. A space for an operator to operate at the time of formation increases, which causes a problem that a region used for operating the apparatus, that is, a substantial installation area of the apparatus increases.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and has as its object to provide excellent operability by performing input / output of a document and input / output of copy paper in front of an operator.

[0015]

[Embodiment 1] An embodiment of the present invention will be described below with reference to FIGS. In this embodiment, a copying machine will be described as an image forming apparatus. The same applies to the following embodiments.

The copying machine according to the present embodiment is shown in FIGS.
As shown in FIG. 1, the apparatus includes an apparatus main body 1 as an image forming unit, and a document cover device 2 provided on an upper surface side of the apparatus main body 1.
And a stationary document pressing device (document cover) 2a that covers a contact glass (document table) 8 on the upper portion of the apparatus main body 1.

The stationary original pressing device 2a is supported by a support shaft 28 (FIG. 1) at the end of the automatic original traveling device 3 so as to be openable and closable in the directions of arrows X and Y, and opens the stationary original pressing device 2a in the X direction. By doing so, the front side of the apparatus main body 1 (arrow F in the figure)
The document placed on the contact glass 8 is fixed at a predetermined position by closing the stationary document pressing device 2a in the Y direction. .

As shown in FIG. 1, the contact glass 8 has a stationary original reading section 8a formed on the front side (the direction of the arrow F in the figure) of the apparatus main body 1 and a rear side view of the apparatus main body 1 in the figure. A traveling original reading section 8b is formed on the side of arrow R). Thus, the copying machine is capable of reading the image information by placing the original M on the stationary original reading unit 8a, and the original conveyed by the automatic original traveling device 3 onto the traveling original reading unit 8b. That is, copying in the traveling original reading mode for reading image information of the traveling original is enabled.

Generally, the stationary original reading section 8a of the contact glass 8 has a size slightly larger than the maximum original size in order to place the original M stationary, and a relatively large size is required. It is assumed that the traveling original reading unit 8
b may have a certain width for moving the original M to obtain image information, and the dimension in a direction perpendicular to the original traveling direction is almost the same size as the stationary original reading unit 8a. It is sufficient if the width is relatively narrow in the document traveling direction.

For example, if the maximum document size is A3 size (4
20 mm × 297 mm), and when the longitudinal direction of the original is placed in the front-rear direction of the copying machine, the stationary original reading unit 8a
Is formed in a size of about 450 mm × 330 mm, while the traveling original reading section 8b is formed in a size of about 50 mm × 330 mm.

The maximum document size is A4 size (29
7 mm × 210 mm), when the longitudinal direction of the original is placed in the front-rear direction of copying, and when the maximum size of the original is reduced, the stationary original reading unit 8 a
While it is formed to have a size of about 330 mm, the traveling original reading section 8b is formed to be substantially the same as the case where the maximum original size is A3.

Accordingly, when both reading sections are juxtaposed in the document traveling direction and juxtaposed, the size of both reading sections required on the upper surface of the apparatus main body 1 is 500 m when the maximum document size is A3 size.
mx 330mm, 330mm x 330 for A4 size
mm dimensions are required. For this reason, as will be described later, it is possible to set a document from the front side of the apparatus main body 1 to the automatic document feeder 3 and the stationary document reading section 8a on the front side of the apparatus main body 1, so that the operability of setting the document is improved. Does not lead to a decrease.

Static document pressing device 2 of automatic document traveling device 3
A document feed tray 4 on which a document to be supplied to the scanning position of the apparatus main body 1 is placed is provided on the upper side of the arrangement side of a. The document feed tray 4 is provided so as to be inclined in the direction of arrow X so as not to contact the opened static document pressing device 2a.

As shown in FIG. 4, the automatic document feeder 3 has a document feed port 3a formed on the upper portion so as to face the stationary document pressing device 2a, and a document placed on the document feed tray 4. Paper feed roller 29 for feeding M and stationary document pressing device 2
a discharge roller 32 for discharging the original M onto the document a, and a document discharge opening 3b for discharging the original M from the discharge roller 32 to the outside
Is provided between the paper feed roller 29 and the paper discharge roller 32 so as to reverse the document fed by the paper feed roller 29, and is a curved conveyance guide formed as a document conveyance path. 31 and a guide roller 30 for transporting the document M to the transport guide 31 are provided. The paper feed roller 29, the guide roller 30, and the paper discharge roller 32 constitute a document supply / discharge unit.

Thus, the document M placed on the document feed tray 4 of the automatic document feeder 3 is fed by the feed roller 29, and is transported by the guide roller 30 to the transport guide 31.
And is reversed by the transport guide 31. The inverted document is conveyed to the scanning position B in the traveling document reading section 8b of the contact glass 8 of the apparatus body 1 while being conveyed.
It is optically scanned at (the home position of the exposure unit 34 in a scanning original reading mode described later), and is ejected onto the stationary original pressing device 2 a by the ejection roller 32.

Therefore, the automatic document feeder 3 is designed to discharge the discharged document to the upper portion of the stationary document pressing device 2a.
By forming the document discharge port 3b, the static document pressing device 2a can be used as a discharge document discharge tray. This eliminates the need to provide a separate document discharge tray, so that the configuration can be simplified, and as a result, the cost for manufacturing the apparatus can be reduced.

The automatic document traveling device 3 is provided with a paper guide 33 so as to be detachable from the main body of the automatic document traveling device 3 so as to cover the outside of the transport guide 31.
Accordingly, when a trouble such as a paper jam (jam) occurs inside the transport guide 31, the jam can be easily removed simply by removing the paper guide 33.

As shown in FIG. 1, the automatic document feeder 3 and the document feed tray 4 are located above the stationary document reading section 8a of the contact glass 8 which occupies a relatively large size on the upper surface of the apparatus main body 1. The projected space Q1 is provided so as to include at least a part thereof.

In this embodiment, the automatic document feeder 3 and the document feed tray 4 are partially included in the space Q1 in which the stationary document reading section 8a of the contact glass 8 is projected upward. May be completely included.

While scanning, the reflected light from the original M is taken in and guided to a photosensitive drum 18 disposed below the exposure optical device 16. In the exposure scanning by the exposure optical device 16, the exposure scanning unit 17 constituted by the exposure lamp 9, the reflection plate 9a, the mirror 10 and the mirror 11 moves from the standby position (home position) A to the front side to the rear side of the apparatus main body 1. That is, it is performed by moving in the direction of arrow R.
The home position of the exposure scanning unit 17 differs depending on the original reading mode of the copying machine described later.

Around the photosensitive drum 18, there are provided a main charger 19, a developing device 20, a transfer charger 21, a cleaning device 22, and a not-shown static eliminator.

And this guide plate 23
A fixing device 24 including a pair of rollers arranged vertically is provided on the end side in the discharge direction. The above-described paper discharge tray 6 is provided on the paper discharge side of the fixing device 24.

On the other hand, a registration roller 25 for synchronizing the paper feeding with the movement of the exposure lamp 9 for optical scanning is provided near the paper feeding side of the transfer charger 21. Further, below the transfer charger 21, a transport roller 26 for transporting the paper from the manual paper feed tray 7a or the paper feed cassette 7b is provided. A curved conveyance guide 27 is arranged between the registration roller 25 and the conveyance roller 26 so that the sheet conveyed by the conveyance roller 26 is reversed.

The copying machine includes a document feed port 3a and a document discharge port 3b of the automatic document feeder 3, a stationary document pressing device 2a, an operation panel 5, and a sheet feed / discharge port 1 of the apparatus body 1.

The transfer processing unit 43 develops the electrostatic latent image formed on the photosensitive drum 18 by exposure to light from the exposure optical device 16 as a toner image, and transfers the toner image on the paper. Further, the transfer process unit 43 conveys the transferred paper to the fixing device 24, and heats and presses the toner image on the paper with the fixing device 24 to fix the toner image.

The automatic document traveling device 3 and the transfer process section 43 are driven and controlled by a control device 39 described later.

Further, in the copying machine, as described above, a still original reading mode for reading an original placed on the still original reading section 8a of the contact glass 8 and obtaining image information,
A traveling original reading mode for reading an original traveling on the traveling original reading section 8b of the contact glass 8 and obtaining image information can be executed.

The operation of the copying machine in each copy mode will be described below. In the stationary original reading mode, as shown in FIG.
The home position A of the exposure scanning unit 17 is set on the operation panel 5 side of the camera. The exposure scanning unit 17 moves from the home position A in the direction of the arrow and moves on the stationary original reading unit 8a of the contact glass 8. The original placed on the scanner is exposed and scanned.

On the other hand, in the scanning original reading mode, as shown in FIG. 6, the home position B of the exposure scanning unit 17 is set below the automatic original traveling device 3 of the apparatus main body 1, and the exposure scanning unit 17 The original conveyed into the automatic original traveling device 3 is scanned while waiting at the home position B.

The exposure lamp 9 of the exposure scanning section 17
And the reflection plate 9a constitute an exposure unit 34.
As shown in FIG. 7, the exposure unit 34 has a guide bar 3 at an end portion orthogonal to the moving direction of the exposure unit 34.
7 is provided on the lower surface of the guide bar 37. A sliding contact member 37a formed of an elastic body such as rubber or the like sliding on a guide rail 38 provided outside the inside of the apparatus main body 1 is provided. . Therefore, the exposure unit 34 is guided by the guide rail 38 and moves to the home position B in the scanning original reading mode or the home position A in the above-mentioned stationary original reading mode.

The apparatus main body 1 also includes an exposure unit 34.
The exposure unit 3 is located near the home position B
There is provided a home position sensor 35 for detecting the presence of the home position sensor 4. The exposure unit 34 is provided with a detection bar 34 a in parallel with the guide bar 37.
The exposure unit 34 is detected when a reaches the detection area of the detection unit 35a of the home position sensor 35. That is, the exposure unit 34
When the detection bar 34a reaches the detection section 35a of the home position sensor 35, it is detected that the detection bar 34a has reached the home position B which is a standby position in the scanning original reading mode.

Below the home position sensor 35, a solenoid 36 driven based on a detection signal of the home position sensor 35 is provided as shown in FIGS. A substantially inverted L-shaped lock member 36a is provided on the upper portion of the solenoid 36, and the tip of the lock member 36a is located between the detection bar 34a and the guide bar 37 of the exposure unit 34, and the arrow C It is movable in the D direction. By moving the lock member 36a in the direction of arrow C, the tip of the lock member 36a is exposed.
The guide bar 37 is driven by a solenoid 36 so as to contact the upper surface of the guide bar 37 and press the guide bar 37 toward the guide rail 38.

The solenoid 36 drives the lock member 36a based on a detection signal of the home position sensor 35. In other words, when the exposure unit 34 has reached the home position B, a detection signal is output from the home position sensor 35, and therefore, FIG.
As shown in (1), the lock unit 36a is brought into contact with the guide bar 37 of the exposure unit 34, and the slide contact member 37a is pressed against the guide rail 38 via the guide bar 37, thereby fixing, that is, locking, the exposure unit 34. It has become.

On the other hand, if the detection signal is not output from the home position sensor 35, the solenoid 36 shown in FIG.
As shown in (b), the lock member 36a is maintained in a state of being moved in the direction of arrow D. However, when the scanning unit is switched from the scanning original reading mode to the stationary original reading mode while the exposure unit 34 is fixed, the solenoid 36 locks the lock member 36a based on the switching signal.
Is driven in the direction of arrow D, and the sliding member 3 of the guide bar 37 is moved.
The contact between the guide rail 7a and the guide rail 38 is released.

The driving of the solenoid 36 is controlled by a control device 39 described later.

As described above, the exposure unit 34 is fixed at a predetermined position by the lock member 36a of the solenoid 36 in the scanning original reading mode. Exposure scanning can be performed stably without being affected by vibration, and as a result, the quality of a formed image can be improved.

Further, as shown in FIG.
A control device 39 including a CPU or the like as control means is provided. The control device 39 includes a document detection sensor 40 that detects the presence or absence of a document in the document feed tray 4 and the size of the document in the automatic document traveling device 3. An opening detection sensor 41 for detecting whether or not the stationary document pressing device 2a is open, and an exposure unit driving device 42 for driving the exposure unit 34 are connected.

Accordingly, the control device 39 controls the copying process in each scanning mode of the copying machine based on the flowchart shown in FIG.
Here, an explanation will be given assuming that the automatic document feeder 3 is SPF and the stationary document pressing device 2a is OC.

First, when the power of the copying machine is turned on, SP
It is determined whether there is a document of F (S1). At this time, if the detection signal of the document detection sensor 40 is ON, it is determined that the document is present in the SPF, and then it is determined whether or not the OC is open (S2). Here, if the detection signal of the opening detection sensor 41 is OFF, it is determined that the OC has not been opened, and the process proceeds to S3.

In other words, if there is a document in the SPF and the OC is not released, the control device 39 determines the scanning document reading mode, drives the exposure unit driving device 42, and moves the exposure scanning section 17 to the home position. B (FIG. 6) (S3). Next, when the copy button is turned on (S4), the driving of the SPF is started (S5), and the copying process is started (S6).

On the other hand, if it is determined in S1 that there is no original in the SPF, or if it is determined in S2 that the OC is open, the process proceeds to S7.

That is, if there is no document in the SPF or the OC is open, the control device 39 determines that the mode is the static document reading mode, drives the exposure unit driving device 42, and controls the exposure scanning section 17 to operate. It is moved to the home position A (FIG. 5) (S7). Next, when the copy button is turned on (S8), exposure scanning by the exposure optical device 16 is started (S9). Then, the copying process is started (S6).

Next, it is determined whether or not the copying process in each scanning mode has been completed (S10). If it is determined that copying has been completed, the copying machine is set to a copy standby state or the power of the copying machine is turned off. On the other hand, if it is determined that the copying has not been completed, the process proceeds to S1, and the selection of the scanning mode and the copying process are repeated.

Accordingly, if it is determined that the automatic document feeder 3 has a document and the release detection sensor 41 does not detect the release of the stationary document pressing device 2a, the controller 39 scans the exposure unit 34. The exposure unit driving device 42 is driven and controlled so as to move to the home position B in the original reading mode.
If the opening of the stationary document pressing device 2a is detected by
The exposure unit driving device 42 is drive-controlled so that the exposure unit 34 moves to the home position A in the stationary original reading mode.

As described above, according to the copying machine having the above-described configuration, the document feed port 3a and the document discharge port 3b of the automatic document feeder 3, the stationary document pressing device 2a, and the operation panel 5
And the paper supply / discharge port 1a of the apparatus main body 1 are arranged so that their operation directions are the same, so that the movement of the operator in setting and taking out the original / paper can be reduced. This makes it easy to set and take out originals and papers, thereby improving the operability of the apparatus.

Therefore, according to the copying machine of this embodiment,
Improving operability because copying in the static original reading mode and original / paper feeding and various operations in copying in the scanning original reading mode can be performed from the same side of the apparatus body 1 of the copying machine. Can be.

The document feed port 3 of the automatic document feeder 3
a and a document discharge port 3b, a stationary document pressing device 2a,
The operation panel 5 and the paper supply / discharge port 1a of the apparatus main body 1
Since at least a part of each of these members is included in the projection space of the contact glass 8 above the stationary document reading section 8a, the document feeding section and the sheet feeding section are conventionally separated. The width on the front side of the apparatus can be made smaller than when the copier is separately arranged in the left-right direction. Thus, even if a wall or another device is arranged in a direction orthogonal to the operation direction of the device, that is, in the left-right direction of the device main body 1, it is sufficient if there is a space that can be operated only in the operation direction. Installation area can be reduced.

Further, the sheet discharge tray 6 and the sheet feed section 7 are formed such that at least half of the depth thereof is formed inside the apparatus main body 1 at the sheet supply / discharge port 1a rather than the operation panel 5. The operator can take out the paper discharged onto the paper discharge tray 6 without retreating from the operation position of the operation panel 5. As a result, the space for the operator to operate during copying can be reduced, and the actual installation area of the apparatus can be reduced.

Therefore, it is possible to provide an image forming apparatus such as a copying machine which is excellent in the operability of the apparatus and can reduce the size of the apparatus.

Further, in this copying machine, the home position A of the exposure unit 34 in the static original reading mode is set.
Is set on the operation panel 5 side, and the automatic document feeder 3 is disposed on the side opposite to the operation panel 5 with respect to the image reading area (the static document reading section 8a) of the contact glass 8. Thus, the traveling original reading section 8b can be separated from the stationary original reading section 8a on the upper surface of the apparatus main body 1. In addition, by arranging the automatic document feeder 3 so that the document supply / discharge portion faces the operation panel 5, the operability in document supply / discharge can be improved for the operator at the operation panel 5. Can be achieved.

As a result, the automatic document feeder 3 and the stationary document pressing device 2a can be effectively arranged on the apparatus main body 1, so that the size of the apparatus can be reduced.

In this embodiment, as shown in FIG. 3, the stationary document pressing device 2a is rotatably supported by the support shaft 28 at the discharge end of the automatic document traveling device 3. The present invention is not limited to this. For example, as shown in FIG. 11, the end of the stationary original pressing device 2a on the automatic original traveling device 3 side is extended, and the automatic original traveling device 3 is disposed on the stationary original pressing device 2a. May be established. In this case, the automatic document traveling device 3 also rotates in the direction of the arrow with the opening and closing of the stationary document pressing device 2a, so that the position of the automatic document traveling device 3 can be effectively used as the contact glass 8. Therefore, the size of the apparatus main body 1 can be reduced, that is, the size of the entire copying machine can be reduced.

[Embodiment 2] Another embodiment of the present invention will be described with reference to FIGS.
It is as follows. For the sake of convenience, members having the same functions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. The same applies to the following embodiments.

FIG. 12A shows a copying machine according to this embodiment.
As shown in FIG. 1B, an automatic document traveling device 52 is arranged substantially at the center of a stationary document pressing device 53 provided on the apparatus main body 1 so as to be freely opened and closed.

According to the above configuration, the automatic document feeder 52

In particular, in the case of the stationary original pressing device 53 corresponding to a large original M, the automatic original traveling device 52 is arranged close to the operation panel 5 side.
As shown in FIG. 11, it is easier to feed and discharge the original M than when the automatic original traveling device 3 is provided at the end opposite to the operation panel 5 of the stationary original pressing device 2a. Can be.

Further, in this copying machine, FIG.
The presence or absence of a document in the automatic document feeder 52 is detected by the document detection sensor 40, and the opening of the stationary document pressing device 53 is detected by the opening detection sensor 41. I do.
Each of the following embodiments also includes a document detection sensor 40 and an opening detection sensor 41, and is assumed to be driven and controlled by the control device 39.

Therefore, in this copying machine, the opening detection sensor 4
When the release of the static original pressing device 53 is detected by the control unit 1, the exposure unit driving device 42 moves the exposure unit 34 to the home position A in the static original reading mode, as shown in FIG. In the case where the opening of the stationary document pressing device 53 is not detected by the opening detecting sensor 41 and the presence of the document M in the automatic document traveling device 52 is detected by the document detecting sensor 40, FIG.
As shown in FIG. 2B, the exposure unit 34 is moved to the home position C in the scanning original reading mode by the exposure unit driving device 42. Also, the opening detection sensor 41
When the opening of the stationary document pressing device 53 is not detected by the
If the presence of the document M in No. 2 is not detected, the exposure unit drive unit 42 moves the exposure unit 34 to the home position A in the stationary document reading mode.

In this embodiment, the stationary original pressing device 53
Has been described in the case where the automatic document traveling device 52 is disposed substantially at the center of the document. For example, as shown in FIG. 13, the automatic document traveling device 52 is provided on the stationary document pressing device 53 so as to be movable in the directions of arrows F and R. May be. In this case, the automatic document feeder 52 is disposed at the end of the stationary document pressing device 53 in the direction of the arrow R, and is manually operated by an operator.
It is pulled out in the direction of arrow F, and is used.

The apparatus main body 1 is provided with a movement sensor (not shown) so as to detect when the automatic document feeder 52 is pulled out. When the detection signal of the movement sensor is ON, that is, when the automatic original traveling device 52 moves to the operation panel 5 side, the exposure unit driving device 42 moves the exposure unit 34 to the home position in the scanning original reading mode shown in FIG. C is to be moved.

Further, in the case of the above configuration, even in the case where the automatic original traveling device 52 is located at the home position B, copying in the scanning original reading mode or the stationary original reading mode is enabled, and the selection of the scanning mode at this time is as described above. It is assumed that the control is performed based on the control method (the flowchart of FIG. 10).

[Embodiment 3] Still another embodiment of the present invention will be described below with reference to FIGS.

The copying machine according to the present embodiment includes an automatic document traveling device 62 as shown in FIG. 15 in place of the automatic document traveling device 3 of the first embodiment. The automatic document feeder 62 is basically the same in configuration as the automatic document feeder 3 of the first embodiment. However, as shown in FIG. The automatic document feeder 3 differs from the automatic document feeder 3 in that the document feed tray 64 and the stationary document pressing device 63 are provided integrally so as to face each other so as to be parallel to each other. That is, the upper portion of the stationary document pressing device 63 also serves as a discharge tray for the document M.

As described above, since the document feed tray 64 is disposed to face the stationary document pressing device 63, when the static document pressing device 63 is opened, the static document pressing device 63
The original M placed thereon is prevented from dropping by the original feed tray 64.

In the automatic document feeder 62, a document feed path 61 communicating with a document feed port 62a and a document discharge port 62b is formed in a substantially U-shape. As a result, the document M supplied from the document feed port 62a is inverted and discharged onto the stationary document pressing device 63 from the document discharge port 62b.

The stationary document pressing device 63 is supported by the support shaft 28 at the lower side of the automatic document traveling device 62 so as to be freely opened and closed.

The drive of this copying machine is controlled by the same controller 39 as in the first embodiment shown in FIG. Therefore, the opening / closing of the stationary document pressing device 63 is detected by the opening detection sensor 41, and the presence or absence of the document M in the automatic document traveling device 62 is detected by the document detection sensor 40.

When the automatic document feeder 62 is not used, the space formed by the static document pressing device 63 and the document feed tray 64 in the copying machine is designed to accommodate the document M or paper in the static document reading mode. It can be used as a temporary stocker.

As described above, since the document feed tray 64 in the automatic document feeder 62 is disposed on the stationary document pressing device 63 also serving as a document discharge tray, the document feed tray 64 and the static document pressing device 63 And the space between them can be reduced. As a result, the automatic document feeder 62 can be made thinner, so that the entire apparatus can be made thinner.

The document feed tray 64 is provided with document guides 65 and 66 for guiding the document according to the width of the document M to be set, for example, as shown in FIG. The document guides 65 and 66 are moved in the directions of the arrows W and Z in conjunction with each other to adjust to the width of the document M placed on the document feed tray 64. This document guide guide 65
Has an inverted L-shaped cross section as shown in FIG.
The upper surface portion 65a prevents the document M from falling. The document guide 66 has the same structure.

The drive mechanism of the document guides 65 and 66 will be described below with reference to FIG. In this figure, the document feed tray 64 is not shown for convenience of explanation.

The one document guide 65 is arranged as shown in FIG.
As shown in FIG. 7, the other document guide guide 66 is connected to the rack 67 by a support portion 68a, while the other document guide 66 is connected to the rack 68 by a support portion 68a. The racks 67 and 68 are
They are provided in parallel with each other. A rotating gear 69 is provided between the racks 67 and 68. The rotating gear 69 has a gear portion 67b provided on the surface facing the racks 67 and 68.
68b meshes with each other. Thus, the movement of one rack 67 causes the other rack 68 to interlock. Moreover, the gear portion 67b at this time
By setting the number of teeth of 68b to be the same, the racks 67 and 68 move with the same width around the rotation gear 69.

The support portions 67 of the racks 67 and 68
a · 68a, as shown in FIG.
4 is inserted through a guide groove 64a formed in a direction perpendicular to the document feeding direction, thereby moving the document guides 65 and 66 in the directions of arrows W and Z along the guide groove 64a. It has become.

The movement center lines of the document guides 65 and 66 are set such that the center line of the document M supplied to the automatic document feeder 62 becomes the exposure center of the apparatus main body 1. In other words, the center of movement of the document guides 65 and 66 may be determined according to the center position of the document M scanned by the apparatus main body 1.

Therefore, when the center position of the document M scanned by the apparatus main body 1 is shifted from the center of the apparatus main body 1, for example, as shown in FIG.
The document guide 65 may be provided only on one of the upper sides. In this case, a fixed guide 64b is formed at a portion of the document feed tray 64 facing the document guide 65. That is, by moving the document guide 65 along the guide groove 64a of the document feed tray 64, the document M to be set is set.
To fit the width of the.

In this embodiment, originals M of various sizes are used.
Are provided on the document feed tray 64 in accordance with the size of the document, but if the size of the document M to be copied is constant,
It is not necessary to provide the movable document guide 65 described above. For example, as shown in FIG.
4, a stationary document pressing device member 64c may be provided. In this case, since a mechanism for moving the document guide 65 is not required, the configuration can be simplified and the cost of the apparatus can be reduced.

[Embodiment 4] Still another embodiment of the present invention is described below with reference to FIG.

In the third embodiment, as shown in FIG.
Since the stationary original pressing device 63 is supported by the support shaft 28 provided below the automatic original traveling device 62, the stationary original pressing device 63 is opened and closed when the stationary original pressing device 63 is opened and closed.
Also, a part of the document feed tray 64 on the side of the automatic document feeder 62 interferes with the paper guide 33 constituting the document feed path 61 of the automatic document feeder 62.

Therefore, the original conveying path 61 near the supporting portion is formed so as to expand and contract so as not to abut on the stationary original pressing device 63, or the original conveying path 61 is rotatably supported by the paper guide 33 so as to be freely opened. It is considered to prevent the interference between the stationary document pressing device 63 and the document conveying path 61 by interlocking with the opening operation of the document pressing device 63. However, the structure becomes complicated, the number of parts increases, and the cost increases. I do. In addition, since the vicinity of the paper guide 33 has a complicated structure, it is difficult to open the paper guide 33 of the automatic document traveling device 62, and the operability of the automatic document traveling device 62 for jam clearance is reduced. Has been invited.

In the copying machine of this embodiment, as shown in FIG. 21, the paper guide 3 of the automatic document traveling device 62 is such that the stationary document pressing device 63 is located above the automatic document traveling device 62.
3 and the document feed tray 64 are supported by a support portion 70 at a connection portion. Thus, when the static original pressing device 63 is opened, the static original pressing device 63
Original document pressing device 6 at the end of automatic document traveling device 62 side
The contact between the document feed path 3 and the document feed path 61, that is, the interference with the document feed path 61 can be eliminated. Therefore, the paper guide 33 of the automatic document feeder 62 and the document feed tray 64
It is not necessary to provide a special mechanism for preventing the paper guide 33 from coming into contact with the stationary document pressing device 63 at a connection portion between the two, and the configuration in the vicinity of the support portion can be simplified.

Fifth Embodiment Still another embodiment of the present invention will be described below with reference to FIGS.

In the copying machine according to the present embodiment, as shown in FIG. 22, the automatic document feeder 62 is provided with a support shaft 71 at an end opposite to the position where the operation panel 5 on the apparatus main body 1 is disposed. The document cover 63 is supported by the support shaft 71. This stationary document pressing device 63
Is connected to a paper guide 60 that covers the automatic document feeder 62, and the original feed path 61 of the automatic document feeder 62 is opened by opening the stationary document pressing device 63.

Thus, by opening and closing the stationary original pressing device 63, the stationary original can be taken in and out of the contact glass 8 and the jam clearance in the original conveying path 61 of the automatic original traveling device 62 can be easily performed.

Therefore, the configuration can be simplified as compared with the case where the paper guide 33 for jam clearance in the automatic original traveling device 62 and the stationary original pressing device 63 are separately opened, and the jam is reduced. Since the processing can be performed only by opening the stationary document pressing device 63, the document removing operation can be performed quickly.

In this embodiment, the stationary document pressing device 63
And the paper guide 60 are integrated, but the invention is not limited to this. For example, as shown in FIG.
The stationary document pressing device 63 includes support plates 72 and 7 provided on both sides of the paper guide 60 of the automatic document traveling device 62.
2 may be integrated with the paper guide 60 by connecting the supporting members 63 a formed at the end of the stationary document pressing device 63.

In this case, as shown in FIG. 24, one end of the paper guide 60 of the automatic document feeder 62 is fixed to the support plate 72 by a fastening member 71a, and the boss 72a is fixed to the other end. The stationary document pressing device 63 is inserted through the support member 63a. The boss 72a is rotatably supported by the supporting member 63a of the stationary document pressing device 63 so as to be rotatable within a predetermined range.

In this case, up to a predetermined range of the stationary document pressing device 63, the paper guide 6 of the automatic document traveling device 62
0 is not released, and only the stationary original pressing device 63 is rotatable. When the stationary original pressing device 63 is opened beyond a predetermined range, the paper guide 60 is rotated by the support shaft 71 in two steps. To open and close the stationary document pressing device 63 and the paper guide 60.

Therefore, when copying in the stationary original reading mode, only the stationary original pressing device 60 can be opened, and when a jam occurs in the automatic original traveling device 62, the stationary original pressing device 63 is moved to a predetermined range. Since the paper guide 60 can be opened by opening it over, the opening and closing of the stationary original pressing device 63 in the stationary original reading mode is more effective than when the stationary original pressing device 63 and the paper guide 60 are rotated integrally. Requires less force.

[Embodiment 6] Still another embodiment of the present invention is described below with reference to FIGS.

Thus, when the stationary original pressing device 83, which is frequently used, is opened and closed, the stationary original pressing device 83 is opened and closed by the support shaft 85, so that the force required to open and close the stationary original pressing device 83 can be reduced. Therefore, the operability of the copying machine can be improved.

Further, when performing the jam clearance in the automatic document feeder 82, it is not necessary to open the stationary original pressing device 83, but only the paper guide 81, so that the jam clearance can be easily and quickly performed. be able to.

Further, since it is necessary to accurately discharge the document M discharged from the document feed tray 84 onto the discharge tray 83a, the document feed tray 84 of the automatic document feeder 82 is required.
The gap at the connection portion between the paper ejection tray 83a and the stationary document pressing device 83 must be as small as possible.

For this purpose, for example, as shown in FIG. 26, the document feed tray 84 of the automatic document feeder 82 is extended via the discharge rollers 32 to the discharge tray 83a on the stationary document pressing device 83. A structure including the provided paper discharge paper guide 86 is conceivable.

At this time, the document supply / discharge tray 212 extends toward the rear side of the apparatus main body 100 so as to be included in the space in which the traveling document reading unit 110a is projected upward as described above. Absent.

In the copying process, the original M is exposed by the exposure optical device 120, and an image corresponding to the original image is formed on the sheet conveyed by the sheet feeding / conveying device 150 by the recording device 130, thereby forming an image. Paper tray 1
The sheets are sequentially discharged onto 60 and stacked.

After the copying is completed, the document cover 200
Is released to remove the original M on the stationary original reading section 110b, and also remove the sheets stacked on the discharge tray section 160.

Next, the replenishment of paper will be described. When there is no paper in the paper feed cassette 140, the paper discharge tray 160b which can be slid forward and backward is slid to the rear side of the apparatus main body 100 to feed the paper feed cassette 140. After the space for the operation is formed, the end of the sheet cassette 140 exposed from the lower opening 100a of the apparatus main body 100 is gripped, pulled out to the front side of the apparatus main body 100, and the paper is placed again.

The entire length of the original M is the original travel roller section 21.
3, the cover 215 rotatably supported by the opening fulcrum 216 at the end in the F direction of the automatic document feeder 210 is rotated above the cover 215 as shown in FIG. Then, the document M is jammed.

When the leading end of the document M is located on the document traveling roller portion 213, the document cover device 200 is rotated to perform the jam processing of the document M as shown in FIG.

According to the copying machine having the above configuration, the document M is placed, the document M and the paper are removed, and the operation panel 170
Is an operation that must be performed for each copy,
At a position near the upper side of the front side.

Further, in use, replenishment of sheets to the sheet cassette 140 as needed can be performed from the operation panel 170 side because the sheet is disposed in the lower opening 100a on the front side of the apparatus main body 100. .

Further, jam clearance of the document M which occurs irregularly can be performed from the front side of the apparatus main body 100 with respect to the automatic document feeder 210, and paper jam processing can be performed by opening the upper portion of the apparatus main body 100. This can be performed from the front side of the apparatus main body 100 simply by performing the above operation.

As described above, according to the present embodiment, the upper surface and the front surface of the copying machine as the image forming apparatus can be effectively used in the operation, so that the operator can approach the apparatus body 100 more closely. It becomes possible. Further, since it is not necessary to use the side surface of the copying machine, even if other devices or walls exist on both side surfaces of the apparatus main body 100, there is no possibility that the operation of the copying machine will be hindered at all.

In this embodiment, the contact glass 11

However, the present invention is not limited to this. For example, the exposure optical device 120 reads the original M with a CCD (Charge Coupled Device),
Even in a method of forming an image by scanning a photosensitive member based on an image information signal converted into a digital signal, the original M is read and transmitted like a facsimile, and the image information transmitted from another device is transmitted. Output, all that satisfy the configuration of the present invention are included.

[0184]

According to the structure of the present invention, at least a part of the document placing tray, the document discharge tray, the sheet supply unit, and the sheet discharge unit are included in the projection space in which the still image reading unit is vertically projected. With such a configuration, the document placing tray, the document discharge tray, the sheet supply unit, and the sheet discharge unit can be arranged on substantially the same straight line.

Thus, even if a wall or another device is arranged in a direction perpendicular to the operation direction of the device, that is, in the left-right direction of the device main body, it is sufficient if there is a space that can be operated only in the operation direction. In addition, the installation area of the device can be reduced. Further, the width of the front of the apparatus can be reduced as compared with the case where the document supply / discharge unit and the paper supply / discharge unit are separately arranged in the left-right direction of the image forming apparatus main body as in the related art. There can be an effect that the size can be reduced.

Further, since at least half of the sheet placement portions of the sheet supply section and the sheet discharge section are disposed inside the apparatus main body, more than half of the sheets are supplied and discharged on the apparatus body side relative to the operation section. be able to. As a result, the sheet can be set and taken out without the operator having to retreat from the operation section, so that the space for the operator to operate at the time of copying can be reduced. The installation area can be reduced.

Therefore, by performing the input / output of the original and the input / output of the copy paper in front of the operator, the operability is excellent,
Moreover, the size of the apparatus can be reduced, and the space for the operator to operate at the time of image formation can be reduced, thereby providing an effect that the actual installation area of the apparatus can be reduced.

Also, an automatic document feeder comprising a document placing tray, a document discharge tray, and a traveling document feed / discharge means is arranged so that a document feed / discharge portion faces the operation section. There is an effect that operability can be improved in a document reading mode using the automatic document traveling device.

Further, the scanning start position for reading an image by the stationary original reading section is set on the operation section side, and the traveling original reading section operates the image reading area of the stationary original reading section. Because it is located on the opposite side of the copying machine,
Since it can be separated from the stationary document reading section, the item document traveling device and the document cover can be arranged at appropriate positions. In addition, by arranging the automatic document feeder such that the document supply / discharge portion faces the operation section, operability in document supply / discharge for the operator in the operation section is improved. Can be achieved.

In the traveling document supply / discharge means, a document feed port formed toward the operation unit side and into which a document from the document tray is inserted, and a document inserted through the document feed port. And a document discharge port for discharging the document from the document reversing and conveying means to the upper portion of the document cover. Thus, the document cover can be used as a discharge tray for receiving discharged documents. This allows
Since there is no need to separately provide a document discharge tray, the configuration can be simplified, and as a result, the effect of reducing the cost for manufacturing the apparatus can be obtained.

Since the traveling original supply / discharge means is provided on the original cover so as to be movable in the direction of the operation section, the traveling original supply / discharge means moves on the original cover in accordance with the original reading mode. Can be done. For example, when reading a traveling document, the traveling document supply / discharge unit can be moved closer to the operator side by moving the traveling document supply / discharge unit in the direction of the operation unit. As a result, the document can be easily set and removed. It can be carried out. Also, at the time of reading a stationary document, the traveling document supply / discharge unit is moved away from the operation unit to move the traveling document supply / discharge unit away from the operator on the document cover. It is possible to prevent a load when opening and closing the cover.

Therefore, by moving the traveling original supply / discharge means on the original cover in accordance with the original reading mode, the original can be easily set and removed in accordance with each reading mode. The effect that the operability of the device can be improved can be obtained.

An automatic document feeder comprising the document placing tray, the document discharge tray, and the traveling document feeder / discharger is arranged on the operation unit side, and the document feeder / discharger of the automatic document feeder is provided. Since the paper part is arranged so as to face the opposite side to the operation unit, an automatic document traveling device that inserts the document from the opposite side of the operation unit and discharges it from the operation unit side to the opposite side of the operation unit again Since the reversal conveyance path of the original in the automatic original transport device can be arranged on the operation unit side, as a result, the jam clearance in the automatic original transport device can be easily performed.

That is, jam clearance of a document which occurs irregularly can be performed from the front side of the apparatus body with respect to the automatic document feeder, and paper jam processing can be performed only by opening the upper part of the apparatus body. The effect that it can be performed from the front side of the apparatus main body can be obtained.

Therefore, with the above configuration, the top and front surfaces of the copying machine as the image forming apparatus can be effectively used in the operation, so that the operator can approach the apparatus body more closely. Further, since it is not necessary to use the side surface of the copying machine, even if other devices or walls exist on both side surfaces of the apparatus main body, there is an effect that the operation of the copying machine is not hindered at all. .
