Description

  The present invention provides a document by conveying the document to a document discharge unit provided below the document placement unit via a document reading unit that reads the document from a document placement unit on which the document is placed. More particularly, the present invention relates to a document reading apparatus in which a see-through unit capable of viewing the document discharge unit is provided on the document placing unit.
2. Description of the Related Art Conventionally, a document reading device provided in an image forming apparatus such as a copying machine, a facsimile machine, or a multi-function machine has a document reading unit that passes through a document reading unit that reads a document from a document setting unit that loads the document. Is provided with a document conveying device (hereinafter referred to as “ADF”) for conveying a document to a document discharge portion provided below the document discharge unit.
In the document reading apparatus, since the document is transported from the document placement unit to the document discharge unit by the ADF, the user removes the document from the document discharge unit. However, in recent years, when it is desired to reduce the size of the document reading device, the distance between the document placement portion and the document discharge portion provided below the document placement portion is narrow. There is a problem that the discharged document cannot be easily visually observed and the user forgets to remove the document.
Therefore, for example, Patent Document 1 discloses a document reading apparatus in which a transparent member that can see through the document discharge unit is provided on the document placement unit. In the document reading apparatus configured as described above, the document discharged to the document discharge unit can be visually observed through the transparent member.
JP 2003-201046 A
However, there is a problem that it is difficult for the user to recognize that the user has forgotten to remove the original on the original discharge section by simply providing the transparent member on the original placement portion as in Patent Document 1.
Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a document reading apparatus and a document that can make a user easily recognize that he / she has forgotten to take a document from a document discharge unit. An object of the present invention is to provide an image forming apparatus provided with a reading device.
In order to achieve the above object, the present invention provides a document placement section on which a document is placed, a document transport means for transporting a document placed on the document placement section, and the document transport means. An image reading unit that reads an image from the document; and a document discharge unit that is provided below the document placement unit and on which the document ejected from the document transport unit is placed. The present invention is applied to a document reading apparatus in which a see-through unit capable of viewing the document discharge unit is provided, and includes a light irradiation means for irradiating the document discharge unit with light. Configured as a document reading apparatus. Here, the see-through portion is formed by a transparent member or an opening, for example.
According to the present invention, since the light irradiating means emits light to the document discharge portion, it is possible to prompt the user to visually check the document discharge portion, and that the document remains in the document discharge portion. It can be easily recognized. Further, since the original discharge section is illuminated by the light irradiation means, the original placed on the original discharge section can be easily seen.
Further, it may be configured to detect the amount of light in the vicinity of the document discharge portion, and to irradiate the document discharge portion when the detected light amount is equal to or less than a predetermined amount. Thus, power saving can be achieved by limiting the light irradiation by the light irradiation means.
On the other hand, the light irradiating means may always irradiate the original discharge section with light, but from the viewpoint of power saving, the original is discharged from the original conveying section to the original discharge section. It is desirable that the document discharge unit is irradiated with light only until a predetermined time elapses after the detection. In this case, since light irradiation by the light irradiating unit is started when the document is discharged to the document discharge unit, the user can be made aware that the document has been discharged to the document discharge unit. , Forgetting to remove the original can be prevented.
In addition, it is preferable that the user recognizes that the user has forgotten to remove the original by detecting the remaining of the original placed on the original discharge unit and emitting a predetermined light source when the detection continues for a predetermined period of time or longer. .
At this time, it is desirable that the predetermined light source is disposed in the vicinity of the fluoroscopic part, for example. As a result, the fluoroscopic part is illuminated by the predetermined light source, thereby allowing the user to recognize that the document has been forgotten.
Here, if the predetermined light source that emits light of a color different from the light emitted by the light irradiating means is used, the user can more clearly recognize that the document has been forgotten.
By the way, the light irradiation means can be used as the predetermined light source. Accordingly, the present invention can be implemented with one light source reduced. Specifically, the user can be made aware of forgetting to remove the original by blinking the light emitted by the light irradiating means.
The present invention may also be understood as an invention of an image forming apparatus provided with the document reading device.
  According to the present invention, since the light irradiating means emits light to the document discharge portion, it is possible to prompt the user to visually check the document discharge portion, and that the document remains in the document discharge portion. It can be easily recognized. Further, since the original discharge section is illuminated by the light irradiation means, the original placed on the original discharge section can be easily seen.

And is schematically configured.
Here, the configuration of the document reading device 2 will be described with reference to FIG.
As shown in FIG. 2, the document reading device 2 includes a document placement unit 21 on which a document is placed, and an automatic document transportation device (document transportation means) that transports the document placed on the document placement unit 21. (Hereinafter, referred to as “ADF”) 22, an image reading unit 23 (an example of an image reading unit) that reads an image from the document conveyed by the ADF 22, and the document placement unit 21. And a document discharge unit 24 on which a document discharged from the ADF 22 is placed.
In the document reading device 2, the ADF 22 transports a document placed on the document placement unit 21 to the document discharge unit 24 via the image reading unit 23, thereby the image reading unit. 23, the image of the original is read.
  The document discharge unit 24 detects a light amount detection sensor 26 (an example of a light amount detection unit) that detects the amount of light in the vicinity of the document discharge unit 24, and detects whether or not a document is placed on the document discharge unit 24. An optical document detection sensor 27 is provided. The amount of light detected by the light amount detection sensor 26 and the document detection signal by the document detection sensor 27 are input to the control unit 5.
The document placing portion 21 is provided with a see-through portion 25 formed of a transparent member such as transparent acrylic, glass, or transparent resin. As a result, the user can see through the document discharge section 24 from above the document placement section 21 via the see-through section 25. A configuration in which the see-through portion 25 is formed by an opening is also conceivable as another embodiment.
Further, in the vicinity of the fluoroscopic part 25, a light source 28 (an example of a light irradiating unit) that irradiates light to the document discharge part 24, and a light source 29 (an example of a predetermined light source) that irradiates the fluoroscopic part 25 with light. Is provided. The light source 28 and the light source 29 are, for example, a light bulb, a fluorescent lamp, a light emitting diode, etc., and the light source 28 and the light source 29 emit light of different colors. Specifically, the light source 28 emits white light and the light source 29 emits red light. The presence or absence of light emission of the light source 28 and the light source 29 is controlled by the control unit 5 by executing a document reading process (see the flowchart of FIG. 3) described later.
Hereinafter, an example of the procedure of the document reading process executed by the control unit 5 in the copying machine X will be described with reference to the flowchart of FIG. In the figure, S1, S2,... Represent processing procedure (step) numbers.
The document reading process is executed by the control unit 5 when a copy start operation is performed on the operation display unit 1 after a document is placed on the document placing unit 21 by a user, for example.
First, in step S <b> 1, the ADF 22 is driven by the control unit 5, so that conveyance of a document by the ADF 22 is started. As a result, the image reading unit 23 reads an image of a document conveyed by the ADF 22. The image read by the image reading unit 23 is subjected to image processing by the image processing unit 3 and then printed on a sheet by the image forming unit 4. Details of this point are the same as those of the conventional apparatus. Description is omitted because there is no difference.
Next, in step S <b> 2, the control unit 5 determines whether or not a document is discharged from the ADF 22 to the document discharge unit 24. Specifically, the determination is made based on a document detection signal input from the document detection sensor 27. Here, the control unit 5 and the document detection sensor 27 when detecting that the document is discharged from the ADF 22 to the document discharge unit 24 correspond to a document discharge detection unit.
If it is determined that the document has been discharged from the ADF 22 to the document discharge unit 24 (Yes in S2), the process proceeds to step S3, while it is determined that the document has not been discharged (S2). (No side) of step S2 is repeatedly executed.
In step S <b> 3, the control unit 5 starts counting the elapsed time since it is determined that the document is discharged from the ADF 22 to the document discharge unit 24.
Next, in step S4, the control unit 5 determines whether or not the amount of light in the vicinity of the document discharge unit 24 is equal to or less than a predetermined amount. Specifically, the determination is made based on the detected light amount input from the light amount detection sensor 26.
Here, when it is determined that the detected light amount is equal to or smaller than the predetermined amount (Yes side of S4), the process proceeds to step S5, and when it is determined that the detected light amount is larger than the predetermined amount (S4). On the No side), the process proceeds to step S6. That is, when the detected light quantity is not less than the predetermined amount and the original discharge section 24 is sufficiently illuminated by the natural light incident from the fluoroscopic section 25 or the like, the light source 28 in step S5 described later is used. Control is performed so as not to irradiate the original discharge unit 24 with light. As a result, power consumption can be reduced.
  In step S <b> 5, the control unit 5 starts irradiating light to the document discharge unit 24 by the light source 28. As a result, the user can be made aware that the document has been discharged to the document discharge unit 24, and forgetting to remove the document can be prevented. Further, since the document discharge unit 24 is illuminated, the user can easily view the document placed on the document discharge unit 24 through the see-through unit 25. Then, the irradiation of light to the document discharge unit 24 by the light source 28 is terminated by the control unit 5 when a predetermined time (for example, about 10 seconds) has elapsed after the start of the irradiation. . In this way, power consumption can be reduced by irradiating light from the light source 28 for a predetermined time when necessary. In another embodiment, the light emission from the light source 28 to the document discharge unit 24 may be terminated on the condition that the document has been removed in step S6 or step S9 described later. It is done.
Next, in step S6, the control unit 5 determines whether or not the document discharged to the document discharge unit 24 remains. Specifically, the determination is made based on a document detection signal input from the document detection sensor 27. Here, the control unit 5 and the document detection sensor 27 when detecting whether or not a document remains in the document discharge unit 24 correspond to a document remaining detection unit.
If it is determined that the document discharged to the document discharge unit 24 remains (Yes side of S6), the process proceeds to step S7, and the document discharged to the document discharge unit 24 is processed. Is determined not to remain (No in S6), the document reading process ends.
In step S7, the control unit 5 determines whether or not 30 seconds (an example of a predetermined time) has elapsed since the time measured in step S3. That is, in the step S7, it is determined whether or not the document detection by the document detection sensor 27 continues for 30 seconds or more.
If it is determined that the original detection by the original detection sensor 27 continues for 30 seconds or longer (Yes in S7), the process proceeds to step S8, where it is determined that it is less than 30 seconds. If it is (No in S7), the process returns to step S6.
  In step S <b> 8, the fluoroscopic unit 25 is illuminated in red by the control unit 5 starting light emission of the light source 29. Here, the control unit 5 when executing such processing corresponds to the remaining light emission means. As a result, the user can be warned that the original remains in the original discharge unit 24, and forgetting to remove the original can be prevented. In addition, since the light source 29 emits light with a different color from the light source 28, even if the light source 28 emits light at the same time, the user can clearly recognize that the user has forgotten to take a document by the light emission of the light source 29.
In the subsequent step S9, as in step S6, the control unit 5 determines whether or not the document discharged to the document discharge unit 24 remains. Specifically, the determination is made based on a document detection signal input from the document detection sensor 27.
Here, when it is determined that the document discharged to the document discharge unit 24 does not remain (No side of S9), the process proceeds to step S10, while it is determined that the document remains. (Yes in S9), the determination in step S9 is repeatedly executed.
In step S10, the controller 5 ends the light emission of the light source 29, and the document reading process ends.
In the present embodiment, the configuration in which the light source 28 and the light source 29 are provided separately has been described. However, a configuration in which only one common light source that also serves as the light source 28 and the light source 29 is provided is another example. Is considered.
Specifically, when the common light source is used for illuminating the document discharge unit 24 in step S5, the common light source is turned on and used for a warning about missing a document in step S8. It is conceivable to blink the common light source. Thereby, one light source can be reduced.
