In addition to the image forming unit 15, the document pressing unit 27, the first to third paper feeding cassettes 23a to 23c, the manual feed tray 29, and the front cover 30 described above, there are many movable units in the multifunction machine 11.

  The first vibration detection sensor 24a is provided on the front side of the multifunction machine 11, here, beside the operation unit 13. The second vibration detection sensor 24b is provided on the side of the multifunction machine 11. The first and second vibration detection sensors 24a and 24b are respectively movable parts, that is, the document retainer 27, the first to third paper feed cassettes 23a to 23c, the manual feed tray 29, the front cover 30, and other movable parts. Detect the generated vibration. As the first and second vibration detection sensors 24a and 24b, for example, MEMS (Micro Electro Mechanical Systems) sensors are adopted. The first and second vibration detection sensors 24a and 24b may be provided inside the multifunction machine 11, respectively.

  Next, the configuration of the control unit 12 included in the multifunction machine 11 will be described. In FIG. 3, the control unit 12 includes an analysis unit 31, a state grasping unit 32, and a notification unit 33. The analysis unit 31 analyzes the vibration detected by the first and second vibration detection sensors 24a and 24b. The state grasping section 32 grasps the state of the movable section from the analysis result by the analyzing section 31. The notification unit 33 notifies the state of the movable portion grasped by the state grasping unit 32. These configurations will be described later in detail.

  Next, the flow of processing when image formation is performed in the multifunction machine 11 will be described. FIG. 4 is a flowchart showing the flow of processing when image formation is performed using the multifunction machine 11.

  Referring to FIG. 4, the user goes to the place where the multi-function peripheral 11 is installed, carrying a document for image formation, for example, copying. Then, the user opens the document presser 27 so that the multifunction peripheral 11 is in the state shown in FIG. Then, a document is set on the mounting table 26, and the document holder 27 is closed so as to obtain the state shown in FIG. In these series of flows, the first and second vibration detection sensors 24a and 24b detect vibration (in FIG. 4, step S11, hereinafter, “step” is omitted). In this case, the vibrations based on the movement of the document holder 27 are mainly detected. In this case, since the document retainer 27 is opened or closed, vibration due to the movement of the document retainer 27 when it is opened and vibration due to the movement of the document retainer 27 when it is closed occur. To detect. Further, the mounting positions of the first and second vibration detection sensors 24a and 24b are different. That is, the first and second vibration detection sensors 24a, 24b are provided at a distance. Therefore, the vibration detected by the first vibration detection sensor 24a and the vibration detected by the second vibration detection sensor 24b are different.

  After that, the analysis unit 31 analyzes the vibration detected by the first and second vibration detection sensors 24a and 24b (S12). In this case, specifically, the vibrations of the original document holder 27 stored in the hard disk 17 in the normal state when the document holder 27 is opened and when the document holder 27 is closed are detected by the first and second vibration detection sensors 24a and 24b, respectively. The vibrations at the time of opening and the vibrations at the time of closing are compared, and it is determined whether or not the difference between the respective vibrations exceeds a predetermined threshold, and how much the timing for detecting the vibrations is deviated. .. In this way, the document retainer 27 as the movable portion is pulled, and the state of the multifunction machine 11 is grasped (S13).

  If it is determined that the vibration difference exceeds a predetermined threshold value, it is determined to be abnormal, and if it does not exceed the predetermined threshold value, it is determined to be normal. That is, for example, if the state in which the document retainer 27 is attached to the main body of the multifunction peripheral 11 becomes loose due to aging of the connecting portions 28a and 28b, the document retainer 27 may not be properly closed. is there. In such a case, the vibration when the document holder 27 is closed under normal conditions differs from the vibration detected by the first and second vibration detection sensors 24a and 24b. If this difference exceeds a predetermined threshold value, it is determined to be abnormal.

  If it is determined that the state of the multifunction device 11 is abnormal (YES in S14), the notification unit 33 notifies that effect (S15). That is, the fact that an abnormality has occurred is notified. FIG. 5 is a diagram showing an example of the display screen 21 in this case. Referring to FIG. 5, on display screen 21, a message 41 "Please check the state of pressing the document" and a character "OK" are displayed, and the display transitions to the next by pressing. The key 42 to be displayed is displayed. In this case, for example, on the display screen 21, the fact that the state of the document holder 27 is abnormal is displayed in characters to inform the user. On the other hand, if it is determined in S14 that it is not abnormal, that is, normal (NO in S14), no particular operation is performed, that is, nothing is displayed on the display screen 21, and the next vibration is generated. It waits until the detection of (S16).

  With this configuration, the vibration is detected and analyzed, and the state of the movable portion of the multifunction machine 11 is grasped from the analysis result. Therefore, various sensors, such as a sensor for measuring a physical state, The state of the multifunction machine 11 can be grasped without providing a sensor or the like for detecting the amount of magnetism. That is, the first and second vibration detection sensors 24a and 24b that detect vibration also serve as a plurality of detection sensors. Then, such a multifunction device 11 can be appropriately operated with an inexpensive configuration.

  That is, in the present embodiment, the above-described vibration detection sensors 24a and 24b are used in place of the types of detection sensors that must be provided, and various vibrations detected by the vibration detection sensors 24a and 24b are analyzed, It is intended to detect the state of each movable part. According to such a configuration, it is possible to solve the problem caused by the wiring and the skill of the installer based on the use of a large number of sensors without using a large number of sensors.

  Further, the present embodiment is configured to further include the hard disk 17 that stores information on the vibration of the document retainer 27, which is a movable portion in normal times. Then, the analysis unit 31 compares and analyzes the vibration of the movable part at normal time stored in the hard disk 17 and the vibration generated in the movable part detected by the first and second vibration detection sensors 24a and 24b. Therefore, it is possible to more clearly grasp whether or not there is an abnormality.

  Further, in the present embodiment, the first and second vibration detection sensors 24a and 24b are provided in plurality, specifically, two, and the analysis unit 31 detects the two vibration detection sensors 24a and 24b. Since the generated vibration is analyzed, the state of the multifunction machine 11 can be more accurately grasped. That is, even if the vibration detection sensor 24a on one side cannot find a difference in vibration, the vibration detection sensor 24b on the other side can find the difference in vibration and detect the abnormality.

  Further, in the present embodiment, since the notifying unit 33 for notifying the state of the multifunction machine 11 grasped by the state grasping unit 32 is provided, it is possible to inform the abnormal state, for example, when grasping the abnormal state. Therefore, it is possible to avoid that the abnormal state lasts for a long time or is left as it is.

  In the above embodiment, vibration is detected, but the invention is not limited to this, and sound may be detected. That is, the multi-function device 11 includes a movable portion that generates at least one of vibration and sound when moved, and a detection portion that detects at least one of vibration and sound generated by moving the movable portion. A storage unit that stores data of at least one of vibration and sound detected by the detection unit, an analysis unit that analyzes at least one of vibration and sound detected by the detection unit, and an analysis unit It may be configured to include a state grasping unit that grasps the movable state of the movable unit based on the analysis result of. Note that the vibration detection sensors 24a and 24b described above may be configured to also serve as a sensor that also detects sound.

  In the movable part, vibration is generated and sound is generated when the movable part is moved. When the sound is easier to detect, the sound may be detected and analyzed based on the detected sound to grasp the state. In this case, for example, a condenser microphone having a relatively high sensitivity is used as a detection unit that detects a sound generated by the movement of the movable unit. Of course, both vibration and sound may be detected and analyzed. By doing so, the state can be grasped more accurately. When detecting a sound, it is desirable to adopt a configuration that prevents unwanted sounds from being picked up.

  In addition, a vibration generating mechanism that generates vibration at a predetermined timing may be provided in the movable portion that generates vibration. FIG. 6 is a diagram showing a part of a vibration generating mechanism for generating vibration. Here, a part of the vibration generating mechanism provided in the first paper feeding cassette 23a is shown. The upper side in FIG. 6 shows a state in which mating described later is not performed, and the lower side in FIG. 6 shows a state in which fitting is performed.

  Referring to FIG. 6, vibration generating mechanism 43 includes a protrusion 44 provided on first paper feed cassette 23 a and a recess 45 provided on protrusion 44. The vibration generating mechanism 43 also includes a protrusion 47 provided on the main body 46 side of the multifunction machine 11. Both the protrusion 44 and the recess 45 are made of resin, and are provided on the back side of the first paper feed cassette 23a, that is, on the rear side. The projecting portion 47 is provided in the main body 46 at a position where the first paper feeding cassette 23a is provided.

First sheet feeding cassette 23a is inserted in the direction opposite to the direction indicated by an arrow D ₁ of the in Fig. Then, when the first paper feed cassette 23a is set in the main body 46, the recess 45 and the protrusion 47 are fitted together. In this case, it is a snap fit. At the time of this fitting, vibration occurs in the first paper feed cassette 23a. In this case, sound is also generated. That is, the vibration generating mechanism 43 also operates as a sound generating mechanism that generates a sound at a predetermined timing. Further, when the first paper feed cassette 23a is pulled out, vibration and noise are generated when the fitting is released.

  By doing so, even when the vibration due to movement is usually small, the vibration can be detected more appropriately. That is, the vibration generated by the vibration generating mechanism 43 is detected by the first and second vibration detection sensors 24a and 24b, and the difference between the vibrations at the normal time is compared to make the analysis by the analysis unit 31 appropriate. Can be done. Of course, the vibration generating mechanism 43 may have another configuration, in which the protrusions rub against each other or collide with each other due to the movement of the movable part, and the vibration and the sound due to the friction and the collision are detected and analyzed. The analysis by the unit 31 may be performed.

  Further, it may be configured to further include a reception unit that receives the correction of the analysis result by the analysis unit 31. By doing so, it is possible to more accurately grasp the state in which the user's correction is reflected. In this case, for example, it is preferable from the viewpoint of the user interface to adopt a configuration in which a correction inquiry is received by displaying on the display screen 21.

  In addition, the analysis unit 31 may perform analysis by performing at least one of separation of vibration or sound into frequency components by Fourier transform and removal of noise in the region of the base frequency component. By doing so, more accurate analysis can be performed.

  In the above-described embodiment, the identification unit that identifies the user who operates the multi-function peripheral 11 and at least one of the vibration and the sound detected by the detection unit for each user identified by the identification unit. A storage control unit that controls to store data in the storage unit may be provided. By doing so, it is possible to analyze characteristic vibrations and sounds for each user and reflect them in the analysis result. For example, when vibrations and sounds when closing the document holder 27 are different for each user, these are stored in the hard disk 17 for each user and used for analysis by the analysis unit 31. By doing so, the state can be grasped with higher accuracy. Note that the user may be identified by, for example, a user ID or password input via the display screen 21.

  Further, in the above embodiment, a determination unit that determines whether or not the analysis unit 31 can perform analysis based on at least one of vibration and sound detected by the detection unit, and the determination unit causes the analysis unit to perform analysis. If it is determined that the analysis by 31 is impossible, a movable control unit that controls the movable unit to move until the analysis by the analysis unit 31 is possible may be provided. By doing so, the state can be grasped more reliably by performing the analysis. For example, if it is determined that the vibration or sound of the motor for driving the developing device in the image forming unit 15 is small or the detection time is short and analysis by the analysis unit 31 based on the vibration or sound is not possible, the composite The machine 11 itself operates to rotate the motor again to generate vibrations and sounds.

  In the above embodiment, the first and second vibration detection sensors 24a and 24b detect at least one of the vibration and the sound generated by the movement of the movable section at regular intervals. However, the analysis unit 31 may compare and analyze at least one of the vibration and the sound detected in the initial stage and at least one of the vibration and the sound detected periodically. .. For example, in the case of the multi-function peripheral 11 as described above, the vibration and the sound generated by the movement of the movable portion every predetermined period, specifically, every month or every predetermined number of sheets, specifically, every 1000 sheets. At least one of the above is detected. Then, the time-dependent changes of vibration and sound are measured, analyzed, and fed back. With such a configuration, the state of the movable part based on the change over time of the multifunction machine 11 can be appropriately grasped, and it can be useful for maintenance such as notification of the timing of component replacement and notification of the cleaning timing. ..

  Further, the first and second vibration detection sensors 24a and 24b detect at least one of vibration and sound generated by the movement of the movable portion based on the function of the multifunction machine 11, and the analysis unit 31 At least one of vibration and sound detected for each function may be compared and analyzed. As for each function, for example, in the case of the multi-function peripheral 11, each function such as single-sided copy or double-sided copy has a different movable state of the movable section, and the reading section 14 such as reading and copying is movable, but the image forming section 15 is provided. Vibrations and sounds are compared and analyzed for each function that is different in the presence or absence of movement, and for each function due to so-called volume difference, such as small amount printing and large amount printing. By doing so, the state of the multi function peripheral 11 can be grasped more strictly.

  It is to be noted that a movable requesting unit for requesting to move the movable unit is further provided, and the first and second vibration detection sensors 24a and 24b include the vibration and the sound generated by the moving of the movable unit requested by the movable requesting unit. At least one of them may be detected. By doing so, with respect to the acquisition of the vibration or sound data desired by the multifunction device 11 side, the vibration or sound generated by the movable portion that is moved according to the movement request is detected more appropriately, and the analysis unit 31 is performed. The analysis in can be performed more precisely. That is, the vibration or sound data generated in response to the movement request can be stored in association with the operation that has issued the movement request, and can be linked to an appropriate analysis. In this case, for example, the display screen 21 may be required to open and close the back cover, to press the drive roller, to open and close the document holder 27 described above, or to another cover, specifically, for example, , Request opening and closing of the front cover.

  In the above embodiment, the vibration data and the sound data are stored in the hard disk 17. However, the present invention is not limited to this, and the vibration data and the sound data may be stored in the cloud, for example. May be acquired via the network interface unit 18.
