## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an image information input/output device and a control system for controlling the image information input/output device using a mobile device. More particularly, the invention relates to a compound image information input/output device having a copy function, a scanner function, a printer function, a facsimile function, a network communication function and the like, and the invention relates to a control system for controlling the image information input/output device using a mobile device
2. Description of the Related Art
Conventionally, there are known an image information input/output device and its control system in which in the image forming device as the above-described image information input/output device for executing a reading input or a print output of image information, if printing is requested for example, or when failure is generated during the print processing, a sender is informed of the fact that the failure was generated through a network, or a relative distance between a client terminal and the image forming device is previously registered, and when the failure is generated, the client terminal having short distance is informed of the failure through the network for restoration of the failure, or a customer engineer is directly informed of the failure depending upon a degree of the failure.
However, such conventional image information input/output device and its control system have a system in which the relative distances between the client terminals and the image forming device are previously registered, and when a failure was generated, the client terminal having short distance is informed of the failure through the network. Therefore, the notification destination is a fixed client terminal, and a person is not always in front of the fixed client terminal, and this notification method is not efficient.
Further, in the conventional image information input/output device and its control system, when the relative distances between the client terminals and the image forming device are previously registered, and when a failure was generated, the client terminal having short distance is informed of the failure through the network, a notification of failure is sent to a user who did not request the printing only because the distance is short, and this notification method leaves much to be desired.
Further, in the conventional image information input/output device and its control system, when the relative distances between the client terminals and the image forming device are previously registered, and when a failure was generated, the client terminal having short distance is informed of the failure through the network. Therefore, there is inconvenience that a distance between the image forming device and a user who is moving is neglected, effective service for intentional processing of a user who approached the image forming device is not provided for that user beforehand from the image forming device.

The original draft fed by the feeding means 23 is transferred from one end side (left end side) to the other end side (right end side) of the original draft stage 5 by the feeding means 23.
Paper-ejecting means 38 provided on a right side portion of the apparatus is provided with a transfer roller 44, a pinch roller 45 for pressing the original draft against the transfer roller 44, a paper-ejection sensor 46 as original draft detecting means for detecting a rear end of an original draft sent in the paper-ejecting direction, and the like.
A paper-ejection roller 48 is disposed downstream from the original draft ejecting path.
The original draft ejecting path is provided with a gate 49 for turning over the original draft and guiding the same to the original draft stage 5, so that the original draft can be copied on both two sides of a sheet of paper.
The scanner 2 as reading means comprises an exposure lamp 6 as a light source, a first carriage 7 on which a mirror 15 is disposed, a second carriage 9 on which mirrors 8a and 8b are disposed for bending optical path, a lens 10, a CCD sensor 11 for receiving reflection light, and an A/D converter (not shown) for converting an output of the CCD sensor 11, i.e., image data (information) from analogue data into digital data.
The first and second carriages 7 and 9 are connected to each other through a timing belt (not shown), and the second carriage 9 moves in the same direction as the first carriage 7 at 1⁄2 speed thereof.
With this arrangement, the first and second carriages 7 and 9 can scan such that a length of optical path to the lens 10 is constant.
The lens 10 moves to a direction of optical axis when magnification is changed while the focus distance is fixed.
In the CCD sensor 11, one pixel of the original draft corresponds to one element of the CCD sensor.

FIG. 4 is a flowchart for explaining a control method in which when the image information input/output device 1 which executes reading input or print output of the image information such as the compound digital copier for example is subject, the image information input/output device 1 having the short distance radio communication system utilizes the short distance radio communication module 207 and finds out, through radio, each mobile radio terminals 200a, 200b, 200c . . . possessed by the plurality of users located at predetermined positions or arbitrary positions away from the predetermined positions, and the image information input/output device 1 calculates a distance between the image information input/output device 1 and each of the found mobile radio terminals 200a, 200b, 200c . . . , and the calculation result is registered in the database of the mobile telephone control module (radio terminal control module) 220.
First, outline of the control method will be explained. In this method, each of the mobile radio terminals 200a, 200b, 200c . . . is found out through radio, a distance between the image information input/output device 1 and each of the found mobile radio terminals 200a, 200b, 200c . . . , and the calculation result is registered in the database of the mobile telephone control module (radio terminal control module) 220.
The processing in which each of the mobile radio terminals 200a, 200b, 200c . . . is found out through radio, a distance between the image information input/output device 1 and each of the found mobile radio terminals 200a, 200b, 200c . . . , and the calculation result is registered in the database of the mobile telephone control module (radio terminal control module) 220 is periodically actuated by a request event of distant measurement or the interval timer 209.
When the mobile radio terminal is again found, the mobile radio terminal having old finding time is deleted from the database of the mobile telephone control module (radio terminal control module) 220, and the information is renewed to the latest one.
First, the send-output of the short distance radio communication module 217 is minimized, and any one of the mobile radio terminals 200a, 200b, 200c . . . existing near is searched (step S1).
Under this condition, if any of the mobile radio terminals 200a, 200b, 200c . . . is found, the distance, the finding time and identification information of the found mobile radio terminals 200a, 200b, 200c . . . of all of the found mobile radio terminals 200a, 200b, 200c . . . are registered in the database of the mobile telephone control module (radio terminal control module) 200 in a format shown in FIG. 5 (Steps S2, S3).
Next, the send-output of the short distance radio communication module 207 is slightly increased, and the mobile radio terminals 200a, 200b, 200c . . . are searched in the same manner.
At that time, the mobile radio terminals 200a, 200b, 200c . . . which have already been found are also detected at the same time, only identification information of the newly found mobile radio terminals 200a, 200b, 200c . . . except already found mobile radio terminals are registered in the database of the mobile telephone control module (radio terminal control module) 220 in the format shown in FIG. 5 (Steps S2, s3).
Subsequently, the mobile radio terminals 200a, 200b, 200c . . . are searched while increasing the send-output of the short distance radio communication module 207 little by little, and if mobile radio terminals are newly found, they are registered in the database of the mobile telephone control module (radio terminal control module) 220 in the format shown in FIG. 5, and this processing is repeated (steps S4, S5).
This processing is repeated until all of the mobile radio terminals 200a, 200b, 200c . . . registered in the mobile terminal control module 220 or the send-output of the short distance radio communication module 207 becomes maximum value (step S6).
FIGS. 7A and 7B are flowcharts for explaining a procedure in which a fact that a user approached a physical position which is necessary to operate the image information device 1 or receive an original draft is detected by searching the mobile radio terminals 200a, 200b, 200c . . . , a setting is switched to a customized setting required by that user, the private printing processing is started, and reception of the print output original draft is completed.
In this case, a user approached a physical position which is necessary to operate the image information device 1 or receive an original draft is detected by the user judging module 215.
That is, as described above, the user judging module 215 detects any of the plurality of users approaches the image information input/output device 1 based on the distance calculated by the distance calculation module 208 whenever communication is carried out with the mobile radio terminals 200a, 200b, 200c . . . of the plurality of mobile radio terminals by the short distance radio communication module 207.
As described above, the user judging module 215 identifies the user who approached the image information input/output device 1 based on the identification information which identifies the mobile radio terminals 200a, 200b, 200c . . . of the plurality of mobile radio terminals managed by the mobile radio terminal control module 210.
Here, processing of switching the customized setting required by the user, starting of private printing processing, and completion of reception of the print output original draft are periodically actuated by the interval timer 209.
First, the user judging module 215 detects whether a user exists within a 1 m radius of the image forming device 1, and if no user exists with in the distance, that user switches the customized setting, and if a request flag of the private printing processing has been set, the request flag is cleared (steps S11, S12).
This is because that when the setting is switched to the customized setting and the user requesting the private printing processing approached the image forming device 1, the image forming device 1 is being used, the printing processing can not be carried out and then, when the printing processing can be carried out, it is detected whether that user exists within the 1 m radius, and if no user exists, that processing is canceled.
Next, after print processing of a certain user has been completed, the setting is switched to the customize setting, and it is checked whether a user who requests the private printing processing exists within the 1 m radius (steps S11, S13).
Next, it is judged whether the reception of the print output original draft of that user has been completed (step S14).
At that time, when original draft receipt requesting notice is carried out in another task, it is possible to detect that this user approached the image forming device 1 and to complete the communication processing (step S15).
Next, it is checked whether the approaching user requests the private printing, and if the private printing is requested, the request flag is set (steps S16, S17).
Next, it is checked whether the approaching user request the switch to the customize setting, and if switch to the customize setting is requested, its request flag is set (steps S18, S19).
Thereafter, it is checked whether the copy function is being used, and if not, the respective processing is started (step S20, S21).
Here, concerning the switch to the customize setting, it is checked whether there exists a plurality of approaching users, and if there exists the plurality of approaching users, a list thereof is displayed on the display 214, and the appropriate user is selected (steps S22, S23).
If the appropriate user is selected before a predetermined time is elapsed, i.e., if a request flag requesting the switch to the customize setting is set, the switch to the customize setting is started (steps S24, S25)
If the appropriate user is not selected even if the predetermined time has been elapsed, the switch is canceled.
As described above, according to the first embodiment of the present invention, operation of a user for setting his or her own customize environment can be omitted, and optimal operation method and screen quality of the user can obtained more easily.
(Second Embodiment)
As a second embodiment of the present invention, a case in which the invention is applied to a system comprising a digital compound device which is one of the image forming device and a client PC terminal disposed on the network will be explained.
In this second embodiment, first, the modules 207, 208, 209, 210 and 215 as hardware of the digital compound device 1 as explained in the first embodiment for realizing the mobile radio terminal and the short distance radio communication system as shown in FIG. 8, and a system constituted by a general PC terminal basic module 219 having a software driver module 218 which operates the modules 207, 208, 209, 210 and 215 and shares data with the mobile radio terminal control module 210 are connected to each other through LAN on the network as shown in FIG. 9.
In FIG. 9, client terminals 1, 2 (200A, 200B) are terminals possessed by a user M.
A client terminal 3 (200C) is not possessed by an individual, but is a terminal of the same group utilizing the digital compound device 1.
Here, each of the client terminals 1, 2 and 3 has the above-described short distance radio communication system.
FIGS. 10A and 10B are flowcharts for explaining control mode including error processing in which the print processing is started by the image forming device 1, necessary notifications are sent to the client terminals 1, 2 and 3, and each user receives the output original draft.
First, as shown in FIG. 10A, if a print request is generated, and the digital compound device 1 is requested to carry out the print processing from the client terminal 2.
The digital compound device 1 receives the print request from the client terminal 2, and starts the print processing, but it is checked whether the request is from a registered client terminal. If the request is from a client terminal who was not registered, the processing is terminated without sending a notification to the client terminal (step S31).
Next, each distance between a mobile radio terminal possessed by the print requester, the digital compound device 1 and the client terminal (here, distance A0 to An when the print was requested) is obtained (step S32).
It is assumed that when a position of the user M at the time of the print request is a position A, a distance A0 from the position A to the digital compound device 1, a distance A1 to the client terminal 1, and a distance A2 to the client terminal 2 are obtained using the short distance radio communication system of each of the terminals 1 and 2.
At that time, a distance to the client terminal 3 is outside the sphere of communication because the user M does not exist in the communication range of the short distance radio communication system.
As described above, each the obtained distance information A0, A1 and A2 is managed as database commonly possessed by the mobile radio terminal control module 210 of the image forming device 1.
Next, printing processing is prepared, and the image forming device 1 actually starts the print output, but if the printing processing is normally completed or canceled, a print completion notification is sent, and if a failure or error such as jam or paper out is generated, a failure/error communication processing is carried out (steps S33, S35).
First, the print completion communication processing will be explained.
If a user exists at a position B after the printing processing was normally completed, a distance B0 from the position B to the digital compound device 1 and a distance B1 to the client terminal 1 are obtained by database commonly used by the mobile radio terminal control module 210 (steps S34, S36).
Similar to the case of print request, the client terminal 3 is outside the sphere of communication because the user M does not exist in the communication range of the short distance radio communication system.
The distances A0 to A2 when the print request was received and the distances B0 to B2 after the print was completed are used as parameters, and they are formed as a table as shown in FIG. 11 for example, and a flow of notification destination, notification method, and notification control are automatically changed in accordance with the table (step S37).
In this case, since the position B is smaller than a minimum value of a distance that can be detected by the short distance radio system of the digital compound device 1, notification is not sent, the original draft is received, and the job is handled as being completed (steps S38, 39).
If the user M sit in front of the position A, notification is sent to the display of the client terminal 2 on a pop-up screen, and if the position was C, a message is sent with incoming sound using the short distance radio terminal from the digital compound device 1.
If the position is D, since the position is outside the sphere of communication of the short distance radio communication system of the digital compound device 1, notification can not be sent directly, and data concerning the message contents and notification method is sent to the client terminal 3 through LAN, and the notification is sent to the user M from the short distance radio communication system of the client terminal 3.
If the position is E, no terminal can send the notification to the user M, the notification is placed on hold, and a terminal that detected the user M first sends the notification.
In this case, since the output original draft is not received, notification is sent after a predetermined time was elapsed, and this is repeated until the original draft is received by the user M.
Next, the failure/error communication processing will be explained with reference to FIG. 10B.
Like the print-completion notification, using the distances A0 to A2 when the print request was received and the distances B0 to B2 after the print was completed as parameters, a table is formed as shown in FIG. 12 for example, the a flow of notification destination, notification method, and notification control are automatically changed in accordance with the table.
Since the urgent degree of the failure/error notice is high, if notification can not be sent by the short distance radio communication system, the notification is not placed on hold, the range of user to be notified is widened or a mobile telephone that can notify to wider region. In this point, the failure/error notice is largely different.
First, it is checked whether notification can be sent to a mobile radio terminal of the user M by the short distance radio communication system of the digital compound device (MPF) 1 with reference to the shared database of the mobile radio terminal control module 210 (Step S41).
If notification can be sent to the mobile radio terminal of the user M from the digital compound device (MPF) 1, the notification is directly sent to the user M from the digital compound device (MPF) 1 (step S42).
If the notification can not be sent directly, it is checked whether the notification can be sent through the client (PC) terminal, and if yes, the communication contents are sent to the client PC terminal through the network, and the notification is sent indirectly (steps S43, S44).
If even indirectly notification is impossible, users to be notified as shown in FIG. 13 is spread from upper user registered in the print request waiting table, and the notification is tried by the short distance radio communication (steps S45, S46).
If even the above method is impossible, public telephone line is finally used to notify to the mobile telephone of the user by sound mail (step S47).
The failure/error notice is sent and the condition is not restored after a predetermined time, notification is sent to the user by the mobile telephone, it is spread to other print request waiting users (steps S48, S49, S50, S51).
As described above, according to the second embodiment of the present invention, appropriate communication method and means can automatically be selected in accordance with locality of a print requester, proceeding state and failure state can swiftly be grasped, availability of the image forming device can be enhanced.
Further, according to the second embodiment of the present invention, it is possible to reduce the possibility that the original draft is left on the tray because the print original draft is not received.
Therefore, as explained above, according to the present invention, it is possible to provide an image information input/output device in which a distance from a user who is moving is not neglected, and effective service is given to a user who approach beforehand, and to provide a control system for the image information input/output device using a mobile device in which a notification of failure when a failure is generated in the image information input/output device is efficiently sent so that the notification of failure which does not leave much to be desired for the user can be realized.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
