Description

  The present invention relates to an image processing system that performs an abnormal process when an earthquake occurs and an image processing apparatus that constitutes the image processing system.

In recent years, with respect to image processing apparatuses (image forming apparatuses such as printers, facsimile apparatuses, multifunction machines, and image reading apparatuses such as scanners), as disclosed in Patent Document 1 and the like, safety is ensured in the event of a disaster such as an earthquake. Technology development is underway. In particular, an electrophotographic image forming apparatus is provided with a fixing device provided with a heater (heating means) that heats and fixes a developer (toner, etc.) on recording paper (recording material). From the viewpoint of safety, it is important to stop or prohibit heating by the fixing device in the event of an earthquake.
For example, Patent Document 2 discloses a technique for detecting the occurrence of vibration associated with an earthquake or the like and stopping heating in the fixing device. In this patent document 2, the posture and vibration state of the main body casing are detected by an abnormal vibration determination function provided in a storage device such as a hard disk device, and when abnormal vibration is detected, power supply to the fixing device is cut off. A technique for performing control is shown.
On the other hand, in recent image processing apparatuses, having a network-compatible function (providing communication means) is a very general configuration. In addition, in companies, etc., there are a small number of high-performance image processing devices (multifunction devices, etc.) equipped with copying functions, color image processing functions, facsimile functions, etc., and a large number of monochrome printing functions that are frequently used. In many cases, an image processing system that uses a low-function image processing apparatus (such as a printer) by network connection (LAN connection) together with a host device such as a personal computer has been introduced. As a result, the load is distributed for low-function image processing that is frequently used while supporting high-function image processing.

However, the conventional image processing apparatus disclosed in Patent Document 2 has the following problems.
One of the problems is that the provision of a special abnormal vibration detecting means such as a hard disk device equipped with an acceleration sensor increases the cost of the device.
The other is that the image processing device may vibrate when a pedestrian comes in contact or when a foreign object is removed when a jam occurs. In such a case, an earthquake (abnormal vibration) occurs. This is a problem that it is erroneously detected and unexpected processing is performed.
Accordingly, the present invention has been made in view of the above circumstances, and the object of the present invention is to increase the apparatus cost associated with the addition of the earthquake response function by effectively utilizing the network support function of the image processing apparatus. An object of the present invention is to provide an image processing system and an image processing apparatus constituting the image processing system that are effective in suppressing or preventing erroneous detection of earthquakes.

In order to achieve the above object, the present invention is applied to an image processing system in which one or a plurality of first image processing devices and one or a plurality of second image processing devices different from the first image processing devices are network-connected. Is.
The first image processing apparatus includes an abnormal vibration (intensity of a predetermined level or more) in the second image processing apparatus notified from the second image processing apparatus (that is, another image processing apparatus) through the network. On the basis of at least the abnormal vibration detection result acquired by the means (other device abnormal vibration status acquisition means) and the abnormal image vibration control of the first image processing apparatus ( Means (first abnormal vibration control means) for performing control for stopping or prohibiting predetermined processing relating to image processing (including the case where both stop and prohibition are performed) are provided.
On the other hand, the second image processing apparatus includes means for detecting abnormal vibration of the second image processing apparatus (abnormal vibration detecting means) and the second image processing apparatus based on the result of detection of abnormal vibration by the means. A means for performing control during abnormal vibration (second abnormal vibration control means) for the image processing apparatus and a result of detection of abnormal vibration by the abnormal vibration detecting means are notified to the first image processing apparatus through the network. Means (abnormal vibration status notifying means). Here, as a typical example of the control at the time of abnormal vibration, a control for stopping or prohibiting a process of heating and fixing a toner image transferred to at least a predetermined transfer material such as a recording paper can be considered.
With such a configuration, the following operational effects can be obtained.

That is, in the first image processing apparatus on the side of obtaining notification of the abnormal vibration detection result, if there is at least one second image processing apparatus provided with abnormal vibration detection means in the network, It is possible to perform control corresponding to an earthquake (control during abnormal vibration) without providing abnormal vibration detection means in the own apparatus.
As a result, the total cost of the entire image processing system can be reduced as compared with the case where the abnormal vibration detecting means is provided for each image processing apparatus connected to the network.
In the first abnormal vibration control means, when the abnormal vibration is detected in a plurality of the second image processing apparatuses (other image processing apparatuses) within a predetermined time, the abnormality is detected. If the configuration is such that the control at the time of vibration is performed, it is possible to prevent unexpected processing at the time of abnormality due to erroneous detection of occurrence of an earthquake (abnormal vibration) by one image processing apparatus.

On the other hand, the first image processing apparatus is also provided with abnormal vibration detection means for detecting abnormal vibration of the apparatus, and the abnormal vibration detection result in the apparatus and the abnormal vibration acquired by the other apparatus abnormal vibration status acquisition means. It is also conceivable that the abnormal vibration control is performed based on the detection result (abnormal vibration state of the second image processing apparatus).
Thus, the first abnormal vibration control means detects abnormal vibration in a plurality of the first image processing apparatus and the second image processing apparatus (other image processing apparatuses) within a predetermined time. In this case, the abnormal vibration control can be performed, and it is possible to solve the problem that unexpected abnormality processing is performed at least due to an erroneous detection of occurrence of an earthquake (abnormal vibration).

By the way, in general, an image processing apparatus is supported in a swingable manner in a conveyance path of a sheet material such as recording paper or an original used for image processing, and a displacement portion that is displaced when contacting the sheet material is displaced by a predetermined amount. One or a plurality of sheet detecting means for detecting this is provided. The displacement part is also swung by the vibration of the image processing apparatus. Therefore, if the abnormal vibration detecting means detects the occurrence of abnormal vibration based on the detection state of the sheet detecting means satisfying a predetermined condition, the abnormal vibration can be detected at low cost by utilizing existing parts. The configuration can be realized.
Of course, an image storage means for recording and reading information by making a movable magnetic head close to a disk-shaped storage medium and recording and reading information, and abnormal vibrations of the image storage means are detected by an acceleration sensor or the like. An image information storage device such as a hard disk device, comprising: a storage unit abnormal vibration detection unit that detects a magnetic head unit; and a head retraction control unit that performs retraction control of the magnetic head unit based on a detection result of the storage unit abnormal vibration detection unit. A configuration is also possible in which the storage unit abnormal vibration detection means is also used as the abnormal vibration detection means. This is suitable when the abnormal vibration detecting means is provided only in the second image processing apparatus having a small number.

According to the present invention, notification of abnormal vibration detection results can be acquired from another image processing apparatus, and control during abnormal vibration can be performed based on the acquired content, thereby reducing the total cost of the entire image processing system. be able to.
In addition, when abnormal vibration is detected in a plurality of other image processing apparatuses within a predetermined time, it is possible to perform control during abnormal vibration. (Abnormal vibration) It is possible to prevent unexpected abnormal processing from being performed due to erroneous detection of occurrence.
On the other hand, if the own device is also provided with abnormal vibration detection means, and control is performed at the time of abnormal vibration based on the detection result of abnormal vibration in the own device and the detection result of abnormal vibration obtained from another device, a predetermined Regarding the problem that abnormal vibration control can be performed when abnormal vibration is detected by multiple devices in time, and at the time of unexpected abnormal processing due to at least false detection of earthquake (abnormal vibration) occurrence can be solved.

First, a schematic configuration of the entire image processing system X according to the embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 1, the image processing system X includes one or a plurality of image processing apparatuses A provided with an abnormal vibration detection unit, which will be described later, and one or a plurality of image processing apparatuses B different from the above. It is a system that is communicably connected via a network N (whether wired or wireless).
The feature of the image processing system X is that each of the image processing apparatuses A and B discriminates the occurrence state of the abnormal vibration of the own apparatus based on the detection result of the abnormal vibration detected by the other image processing apparatus. It is characterized in that it performs processing at the time of an earthquake (when abnormal vibration occurs) according to.
For this reason, the network N in the image processing system X assumes a communication medium within a range (region) in which abnormal vibration is detected almost simultaneously (for example, within a few seconds) when an earthquake occurs. An example is a local area network (LAN). Of course, if the network is used as a network connecting the image processing apparatuses A and B installed in the range (area) where the occurrence of earthquakes is observed almost simultaneously, WAN or the Internet is part or all of the network N. You can use it.

Next, the configuration of each of the image processing apparatuses A and B will be described with reference to the block diagram shown in FIG.

The operation / display unit 11 is an input / output interface for operation provided with an operation input unit and a display unit including a liquid crystal touch panel or the like.
The image reading unit 12 reads an image (original image) formed on a document. For example, a light source that irradiates the document with light, and a light guide unit such as a reflection mirror that guides the reflected light in a predetermined direction. , And photoelectric conversion means for receiving the light guided thereby and performing photoelectric conversion.
The image memory 13 is a memory for temporarily storing the image data when the document image data is processed.
The data storage unit 14 is an image storage device such as a hard disk device that records and reads image information and other information by recording and reading information by bringing a movable magnetic head unit close to a disk-shaped storage medium. It is.

The image processing unit 16 is configured by a dedicated signal processing circuit or a DSP (Digital Signal Processor), etc., performs various image processing on the document image data, and print data (image data, print job, etc.) used for image formation. Generation, generation of image data to be transmitted to the host device (for example, image data subjected to predetermined encoding such as JPEG format) is performed.

Based on the acquired abnormal vibration detection result, predetermined earthquake control (control during abnormal vibration) to be performed when an earthquake occurs is performed.
On the other hand, the image processing apparatus B has a configuration in which the abnormal vibration detection unit 19 is removed from the image processing apparatus A described above, and the other parts are the same except that the processing contents in the control unit 15 are slightly different. It has a configuration.
In the image processing system X described above, the copying machine is shown as an example of the image processing apparatuses A and B. However, the present invention is not limited to this. For example, a facsimile machine without the image forming unit 17 or A configuration in which another type of image processing apparatus such as a printer that does not have the image reading unit 12 is connected to the network, or a configuration in which various image processing apparatuses are mixed and connected to the network is also conceivable.

Next, the procedure of the earthquake response process whose execution is controlled by the control unit 15 provided in each of the image processing apparatuses A and B in the image processing system X will be described with reference to the flowchart shown in FIG. Hereinafter, S11, S12,... Represent the identification code of the processing procedure (step).
<Processing on Image Processing Apparatus A Side>
First, processing in the image processing apparatus A will be described.
In the image processing apparatus A, first, the control unit 15 monitors whether or not abnormal vibration in the own apparatus is detected by the abnormal vibration detection unit 19 (S11), and the occurrence of abnormal vibration in the own apparatus is detected. In this case, the control unit 15 controls the communication unit 18 to notify all other image processing apparatuses A and B connected to the network N of the detection result of the abnormal vibration through the network N (S12). An example of abnormal vibration status notification means). For this notification, for example, a notification destination is registered in advance and stored in the data storage unit 14 or the like, and each notification destination is notified, or when the network N is a LAN, broadcast transmission is performed within the LAN. It may be possible to do so.
In parallel with the processing in step S12, the control unit 15 monitors the communication status of the communication unit 18, so that abnormal vibration is detected in the image processing device A from another image processing device A connected to the network N. A process for acquiring the notification (detection result of abnormal vibration) through the network N is performed (S13, an example of other apparatus abnormal vibration status acquisition means). For convenience, FIG. 3 shows that the processing is performed in the order of steps S12 → S13, but this is not restrictive.
In addition, the control unit 15 causes the number of units (n units: n = 1, 2,...) Previously set by the process of step S13 within a predetermined time (for example, within a few seconds) before and after the notification in step S12. It is determined whether or not the image processing apparatus A has notified that abnormal vibration has been detected in the apparatus (S14).
Here, if it is determined that there is no notification that abnormal vibration has been detected from other n or more image processing apparatuses A (the number is less than n), the process returns to step S11. , The above process is repeated.

On the other hand, when it is determined that there is a notification that abnormal vibration has been detected from n or more other image processing apparatuses A, the control unit 15 performs predetermined processing related to image processing in the image processing apparatus A. , Stop the processing already in progress, execute control during earthquake (control during abnormal vibration) prohibiting future processing (S15), and then end the earthquake response processing in the image processing apparatus A .
Here, the control part 15 performs the following control as control at the time of an earthquake, for example.
First, during image formation, the power supply to the heater of the fixing device provided in the image forming unit 17 is stopped to stop the process of heating and fixing the toner image transferred to the recording paper. Further, the image forming process by the image forming unit 17 is prohibited until a predetermined release operation is performed from the operation / display unit 11. Similarly, when the image is not being formed, the image forming process by the image forming unit 17 is prohibited until the release operation is performed. This prevents abnormal overheating by the heater.
Further, with respect to the data storage unit 14, the magnetic head accessing the disk as a storage medium is retracted, and data access (reading and writing) in the data storage unit 14 is performed until a predetermined release operation is performed from the operation / display unit 11. Is prohibited. This prevents data loss due to the data storage unit 14 being damaged by vibration.
In addition, during the image reading, the light emission of the light source provided in the image reading unit 12 is stopped. Further, image reading processing (that is, light emission of the light source) by the image reading unit 12 is prohibited until a predetermined canceling operation is performed from the operation / display unit 11. This prevents abnormal overheating due to the light source.

As described above, the image processing apparatus A uses the control unit 15 (an example of the first abnormal vibration control unit and the second abnormal vibration control unit) to detect abnormality by the abnormal vibration detection unit 19 of its own device. Using the vibration detection result (the determination result of step S11) and the abnormal vibration detection result of the other image processing apparatus A acquired by the process of step S13 (an example of the process of the other apparatus abnormal vibration status acquisition unit). When the abnormal vibration is detected in the image processing apparatus A and one or a plurality of other apparatuses within a predetermined time, the control at the time of earthquake is performed (S15). As a result, it is possible to prevent unexpected earthquake control due to erroneous detection of the occurrence of an earthquake (abnormal vibration) in the device itself.
Of course, a configuration in which the processing in steps S13 and S14 is not performed, that is, a configuration in which the control at the time of earthquake is performed based only on the abnormal vibration detection result of the own device (an example of the second abnormal time control means) By having a function of notifying the apparatus, there is an effect that contributes to at least an earthquake response process in the image processing apparatus B described later.
As can be seen from the above description, the image processing apparatus A is both an example of the first image processing apparatus and an example of the second image processing apparatus.

<Processing on Image Processing Device B Side>
Next, processing in the image processing apparatus B will be described.
In the image processing apparatus B, first, when the control unit 15 controls the communication unit 18, an abnormality in each image processing apparatus A notified through the network N from another image processing apparatus A connected to the network N. A process of acquiring the vibration detection result is performed (S21, an example of other apparatus abnormal vibration status acquisition means).
Further, the controller 15 (m units: m = 1, 2,...) Image processing apparatuses A (other images) set in advance by the process of step S21 within a predetermined time (for example, within a few seconds). It is determined whether or not there is a notification from the processing device that abnormal vibration has been detected in the device (S22).
If it is determined that there is no notification that abnormal vibration has been detected from the m or more image processing apparatuses A (the number is less than m), the process returns to step S21, and the above-described processing is performed. The process is repeated.

On the other hand, when it is determined that there is a notification that abnormal vibration has been detected from the m or more image processing apparatuses A, the control unit 15 causes the image processing apparatus B to be the same as the image processing apparatus A described above. The control at the time of earthquake is executed (S23), and then the earthquake response process in the image processing apparatus B is terminated.
As described above, the image processing apparatus B uses the control unit 15 (an example of the first abnormal vibration control unit) to acquire an image acquired by the process of step S21 (an example of the process of the other apparatus abnormal vibration status acquisition unit). Based on the detection result of the abnormal vibration of the processing apparatus A (another image processing apparatus), control at the time of earthquake (S23) is performed.
Accordingly, if at least one image processing apparatus A (an example of the second image processing apparatus) including the abnormal vibration detection unit 19 exists in the network N, the abnormal vibration detection unit 19 is not provided in the own apparatus. Therefore, it is possible to perform control corresponding to an earthquake.
When there are a plurality of image processing apparatuses A connected to the network N, the image processing apparatus B can control the control unit 15 (first abnormal vibration control by setting the set number m to 2 or more. According to an example of the means, when an abnormal vibration is detected in a plurality of other apparatuses (image processing apparatus A) within a predetermined time, the control at the time of earthquake (S23) is performed. As a result, it is possible to prevent unexpected control during an earthquake due to erroneous detection of occurrence of an earthquake (abnormal vibration) in one image processing apparatus A.
In particular, when a large number of image processing apparatuses B perform an earthquake control based on the abnormal vibration detection results of a small number of image processing apparatuses A as in the image processing system X, erroneous detection by one image processing apparatus A may occur. Since it affects the processing of a large number of image processing apparatuses B, the effect of performing earthquake control based on the abnormal vibration detection results of a plurality of image processing apparatuses A is great.
As can be seen from the above description, the image processing apparatus B is an example of a first image processing apparatus.

Here, the image processing system X shown in FIG. 1 has a configuration in which a plurality of image processing apparatuses A and a plurality of image processing apparatuses B are connected to a network, but the present invention is not limited to this. A configuration in which the image processing apparatus A (including the abnormal vibration detection unit 19) and one or a plurality of image processing apparatuses B are network-connected (referred to as a second configuration), or only a plurality of the image processing apparatuses A. A network-connected configuration (referred to as a third configuration), a configuration in which a plurality of image processing apparatuses A and one image processing apparatus B are connected to a network (referred to as a fourth configuration), and the like are also conceivable.
According to the second configuration, that is, the configuration in which steps S13 and S14 in the processing of FIG. 3 are removed and the number m in step S22 is one, the abnormal vibration detection unit for each image processing apparatus connected to the network N Compared with the case where 19 is provided, the total cost of the entire image processing system can be reduced.
According to the third configuration, each image processing apparatus A can be prevented from being unexpectedly processed during an earthquake due to an erroneous detection of occurrence of an earthquake (abnormal vibration) by the apparatus (one unit).
Further, the fourth configuration also leads to cost reduction by the amount that the abnormal vibration detection unit 19 is unnecessary in the image processing apparatus B, as in the configuration shown in FIG. 1, and each image processing apparatus A has its own apparatus. It is possible to prevent unexpected processing at the time of an earthquake due to erroneous detection of occurrence of an earthquake (abnormal vibration). Similarly, by setting the number m in step S22 of FIG. 3 to 2 or more, it is possible to prevent unexpected processing during an earthquake due to erroneous detection of abnormal vibration by one image processing apparatus A.

<Example of Abnormal Vibration Detection Unit 19>
Next, an embodiment of the abnormal vibration detection unit 19 provided in the image processing apparatus A will be described.
The image processing apparatus A includes a conveyance path for recording paper (an example of a sheet material) for image formation conveyed from the recording paper storage unit toward the image forming unit 17, and an image reading unit from the automatic document conveyance device (ADF). A sheet detection sensor 22 is provided in the conveyance path of an image reading document (an example of a sheet material) conveyed toward the image 12.
The abnormal vibration detection unit 19 according to this embodiment also uses the sheet detection sensor 22 as an abnormal vibration detection sensor.
FIG. 4 is a diagram illustrating a schematic configuration of the sheet detection sensor 22.
As shown in FIG. 4, the sheet detection sensor 22 includes a main body portion 24, a displacement portion 25, a switch portion 26 that turns on / off electrical contacts, and the like.
The sheet detection sensor 22 is disposed so that the displacement portion 25 overlaps the sheet material conveyance path 3, and the displacement portion 25 swings by being rotatably supported by the main body portion 24 at one end 25 a thereof. It is supported freely.
When the sheet material (recording paper or document) passes through the conveyance path 3, the displacement unit 25 is displaced in the direction of the broken arrow shown in FIG. 4 by contacting the sheet material, and the rotation end 25b is displaced by a predetermined amount. As a result, the switch unit 26 is clicked (pressed), and the ON / OFF state (contact state) of the switch unit 26 is switched. Thereby, it is detected that the sheet material exists in the conveyance path 3 (that is, the displacement portion 25 is displaced by a predetermined amount). Since the displacement part 25 is displaced by the degree of contact with the sheet material, the displacement part 25 is also displaced when abnormal vibration occurs in the image processing apparatus A. In particular, since the weight portion w is provided at the rotating end, the detection sensitivity of abnormal vibration is enhanced.
The contacts that are turned on / off by the switch unit 26 are connected to the control unit 15 through a predetermined I / O port or the like, and the detection state of the sheet detection sensor 22 is acquired by the control unit 15. Then, the control unit 15 determines whether or not the detection state of the sheet detection sensor 22 satisfies a predetermined abnormal vibration detection condition, and detects the occurrence of abnormal vibration based on the determination result. In other words, in this embodiment, the abnormal vibration detection unit 19 is incorporated in the control unit 15.

Hereinafter, an example of the abnormal vibration detection condition will be described.
For example, let us consider a case where conveying rollers 4a and 4b for conveying a sheet material are arranged before and after the sheet detection sensor 22 in the direction along the conveying path 3 (upstream and downstream in the conveying direction of the sheet material).
In such a case, if the control unit 15 detects that the ON / OFF state of the sheet detection sensor 22 has changed when both the transport rollers 4a and 4b are in a non-driven state (stopped state), abnormal vibration is detected. It is detected that has occurred.
In addition, when a plurality of sheet detection sensors 22 are arranged along the conveyance path 3, a combination (detection pattern) of these sheet detection states (ON / OFF) may occur during normal image processing. It is also conceivable to store in advance a combination that does not exist in a ROM or the like provided in the control unit 15 and detect that abnormal vibration has occurred when the detection state of the sheet detection sensor 22 corresponding to such a combination occurs. It is done.

In addition to the examples shown above, as the abnormal vibration detection unit 19, a storage device such as a hard disk device having a function of detecting the abnormal vibration or tilt and performing a retraction control of the magnetic head is adopted as the data storage unit 14, It is also conceivable that the abnormality detection means (including abnormal vibration detection means) provided in the data storage unit 14 is also used as the abnormal vibration detection unit 19 used for the control during the earthquake by the control unit 15.
A storage device that controls the retraction of the magnetic head in the event of abnormal vibration or the like is a well-known storage device that is already on the market, but in brief, a movable magnetic head unit is placed close to a disk-shaped magnetic storage medium. A storage unit that records and reads information (including image information here), an abnormal vibration that detects abnormal vibration and abnormal inclination of the storage unit (that is, the storage device) by an acceleration sensor and an inclination sensor, etc. And a head retraction control unit that performs retraction control of the magnetic head unit when abnormal vibration or abnormal inclination is detected thereby.
Thereby, in order to prevent the loss of image information when an earthquake occurs, when a storage device with a magnetic head retracting function is employed, this can also be used as an abnormal vibration detection means used for earthquake control.

  The present invention can be used for an image processing apparatus.
