After entering the stay detection range R2, a person (user) who intends to use the image forming apparatus 10 stays in the stay detection range R2 and performs an operation using the user interface 13 or the like.

  The detection of the presence of a person in each of the approach detection range R1 and the stay detection range R2 is performed by analyzing an image captured by the first camera 15 (first camera image). Further, each of the approach detection range R1 and the stay detection range R2 does not need to be set strictly as shown in FIG.

  FIG. 4 is a functional block diagram of the image forming apparatus 10. The image forming apparatus 10 includes a control unit 101, a communication unit 102, an operation unit 103, a display unit 104, a storage unit 105, an image reading unit 106, an image forming unit 107, a photographing / detecting unit 108, , A face registration / authentication unit 109 and a routine processing unit 110.

  The control unit 101 includes, for example, a CPU (Central Processing Unit) and a memory, and controls each unit of the image forming apparatus 10. The CPU executes a program stored in the memory or the storage unit 105. The memory includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores programs and data in advance. The RAM temporarily stores programs and data, and is used as a work area when the CPU executes the programs.

  The imaging / detection unit 108 performs imaging of an imaging target or detection of a moving object. In this example, the photographing / detecting unit 108 is realized by the pyroelectric sensor 14, the first camera 15, and the second camera 16.

  The face registration / authentication unit 109 registers a user who can use the image forming apparatus 10 using a face image of the user in advance. Here, in the registration, a face image of the user is photographed, and a feature amount is extracted from the face image obtained by the photographing. Then, the user ID, the face image of the user, and the feature amount extracted from the face image of the user are stored in association with each other. The face registration / authentication unit 109 performs authentication using the face image of the user when the user attempts to use the image forming apparatus 10. Here, in the authentication, a face image of the user is photographed, and a feature amount is extracted from the face image obtained by the photographing. Then, it is checked whether or not the feature amount obtained by the current shooting matches the already registered feature amount. If there is a match, the use of the image forming apparatus 10 is permitted, and the match is determined. If there is no, the use of the image forming apparatus 10 is prohibited. In the image forming apparatus 10, it is possible to set whether or not to use face authentication. In the image forming apparatus 10 of the present embodiment, it is assumed that the setting for not using the face authentication is performed.

  The standard processing unit 110 generates a standard processing table for causing the image forming apparatus 10 to execute the standard processing, and generates print data including a code image obtained based on the generated standard processing table. I do. Here, in the standard processing, each function (scan, print, copy, facsimile, etc.) executable by the image forming apparatus 10 and various parameters set in association with each function are registered in association with each other. In addition, when the user instructs execution of the routine processing, the function of the routine processing and various parameters are called to execute the processing.

  In the image forming apparatus 10, scan processing, copy processing, print processing, facsimile transmission processing, and facsimile reception processing are performed. The scanning process is a process of reading an image of a document and generating image data. This scanning process is performed by the image reading unit 106.

FIG. 5 is a functional block diagram of the routine processing unit 110 shown in FIG.
The routine processing unit 110 as an example of a setting unit, a first setting unit, a second setting unit, and a registration unit includes a creation unit 111, a storage unit 112, an extraction unit 113, an analysis unit 114, and a collation / setting unit 115. And an instruction unit 116.

  The creating unit 111 creates a routine processing table describing the contents of the routine processing based on the user's instruction received via the user interface 13 or the like. Further, the creating unit 111 instructs the storage unit 112 to register the created routine processing table. Further, the creating unit 111 creates and outputs print data including a code image based on the standard processing table registered in the storage unit 112.

  The storage unit 112 registers (stores) the routine processing table for which registration has been instructed by the creation unit 111. Here, the storage unit 112 is configured by a nonvolatile memory capable of holding stored information without supplying power. Note that the storage unit 112 provided in the image forming apparatus 10 may be used as the storage unit 112 instead of providing the storage unit 112 in the routine processing unit 110.

The extracting unit 113 extracts a code image from an image (first camera image) captured by the first camera 15.
The analysis unit 114 analyzes the code image extracted by the extraction unit 113 and acquires a code included in the code image.
The collation / setting unit 115 performs collation between the code analyzed by the analysis unit 114 and the code registered in the standard processing table registered in the storage unit 112. In addition, when a matching code exists, the matching / setting unit 115 sets various parameters for executing the corresponding routine processing.
The instruction unit 116 outputs an instruction for executing the standard processing set by the collation / setting unit 115 to each unit configuring the image forming apparatus 10.

  Here, the image forming apparatus 10 of the present embodiment operates according to one of two modes having different power consumptions, namely, a normal mode and a sleep mode. When the image forming apparatus 10 operates in the normal mode, power required to execute various processes is supplied to each unit of the image forming apparatus 10. On the other hand, when the image forming apparatus 10 operates in the sleep mode, power supply to at least a part of the image forming apparatus 10 is stopped, and the power consumption of the image forming apparatus 10 becomes smaller than in the normal mode. However, even when the image forming apparatus 10 operates in the sleep mode, power is supplied to the control unit 101, the pyroelectric sensor 14, and the first camera 15, and these units can operate even in the sleep mode. It has become.

  FIG. 6 is a flowchart illustrating a flow of a process regarding control of the mode of the image forming apparatus 10. In this description, it is assumed that the image forming apparatus 10 is set to the sleep mode in the initial state.

  When the image forming apparatus 10 operates in the sleep mode, the control unit 101 monitors the detection result of the amount of infrared rays by the pyroelectric sensor 14 and determines whether a person exists within the detection range F. When the person enters the detection range F, the control unit 101 detects the presence of the person in the detection range F based on the detection result of the pyroelectric sensor 14 (Step 1).

  When detecting the presence of a person in the detection range F, the control unit 101 starts power supply to the first camera 15 and activates the first camera 15 to start photographing the approach detection range R1 (step 2). ). When photographing is started by the first camera 15, the control unit 101 starts a process of analyzing a photographed image (first camera image) acquired from the first camera 15 and detecting a motion of a person (step 3). .

  In the process of detecting the motion of the person started in step 3, the control unit 101 estimates the distance from the image forming apparatus 10 to the person and calculates a motion vector indicating the motion of the person. The process of detecting the movement of the person may be performed by a known method. For example, the control unit 101 may determine the distance from the image forming apparatus 10 to the person based on the size of the body part detected from the captured image. Is estimated. Further, the control unit 101 performs frame processing on the image captured by the first camera 15 and compares the captured images of a plurality of frames in chronological order. At this time, the control unit 101 detects, for example, a toe as a body part of the person, and analyzes a motion of the detected body to calculate a motion vector. For example, the control unit 101 detects the movement of the person after correcting the captured image acquired from the first camera 15 into a planar image (development in planar view).

Next, the control unit 101 determines whether or not the approach of a person within the approach detection range R1 has been detected (step 4). For example, when determining that the person is within the approach detection range R1 and moving in the direction of the image forming apparatus 10, the control unit 101 determines that the approach of the person has been detected (YES in step 4). .
During the period in which the presence of a person is detected by the pyroelectric sensor 14, the control unit 101 performs the process of detecting the movement of the person, and repeats the process of determining the presence or absence of approach in the process of step 4 (step 4). NO in 4).

If an affirmative determination (YES) is made in step 4, the control unit 101 shifts the mode of the image forming apparatus 10 from the sleep mode to the normal mode (step 5). At this time, the control unit 101 instructs each unit of the image forming apparatus 10 to supply power according to the normal mode, and activates each unit of the image forming apparatus 10. At this time, the control unit 101 starts power supply to the second camera 16 and activates the second camera 16.
The control unit 101 does not immediately shift to the normal mode when detecting the presence of a person within the approach detection range R1, but shifts to the normal mode when detecting an approach to the image forming apparatus 10. For this reason, the chance that the image forming apparatus 10 shifts from the sleep mode to the normal mode is reduced when the person has just passed the approach detection range R1.

  Next, the control unit 101 starts a process (stay detection) of detecting whether a person is present (that is, staying) in the stay detection range R2 (step 6). The control unit 101 analyzes the image captured by the first camera 15 to detect a body part of the person, and detects the presence of the person within the stay detection range R2 based on the position and size of the detected part. For example, the control unit 101 estimates the distance from the image forming apparatus 10 to the person based on the size of the detected body part, and specifies the direction in which the person exists based on the detected position of the body part. .

  Next, the control unit 101 determines whether or not a person exists within the stay detection range R2 (step 7). For example, if an affirmative determination (YES) is made in step 7, the stay detection process started in step 6 is continued. Therefore, the control unit 101 repeats the process of detecting the presence of the person in the stay detection range R2 in the normal mode until the presence of the person in the stay detection range R2 is no longer detected.

  Here, it is assumed that the person has moved out of the stay detection range R2 because the work using the image forming apparatus 10 has been completed. In this case, the control unit 101 makes a negative determination (NO) in step 7. Then, the control unit 101 starts counting time using a timer (step 8). That is, the control unit 101 measures the elapsed time from when the person no longer exists within the stay detection range R2 by using the timer.

  Next, the control section 101 determines whether or not a person exists within the stay detection range R2 (step 9). In step 9, after the person no longer exists in the stay detection range R2, the control unit 101 determines whether the presence of the person is detected again. For example, when the person gradually moves away from the image forming apparatus 10 and the person no longer exists in the stay detection range R2, the control unit 101 determines “NO” in step 9 and proceeds to step 10.

  Next, the control unit 101 determines whether or not the time measured by the timer has passed a set period (step 10). The set period is, for example, one minute, but may be set to a time other than one minute. If a negative determination (NO) is made in step 10, the control unit 101 returns to step 9. That is, the control unit 101 determines in steps 9 and 10 whether or not the period during which no person is present in the stay detection range R2 continues for the set period.

  On the other hand, if a positive determination (YES) is made in step 10, the control unit 101 shifts the mode of the image forming apparatus 10 from the normal mode to the sleep mode (step 11). Here, the control unit 101 instructs each unit of the image forming apparatus 10 to supply power in the sleep mode, and stops the operation of each unit of the image forming apparatus 10 to be stopped in the sleep mode. Thereafter, when the control unit 101 stops detecting the presence of a person in the detection range F, the control unit 101 stops the operation of the first camera 15.

Here, it is assumed that the control unit 101 detects the presence of a person again before the set period elapses after the start of time counting by the timer and before the set period elapses after the person no longer exists in the stay detection range R2. In this case, the control unit 101 determines “YES” in step 9 and proceeds to step 12. Next, the control unit 101 stops counting by the timer and resets it (step 12). Then, the control unit 101 stops shifting to the sleep mode due to the person no longer existing in the stay detection range R2, and returns to step 6. That is, the control unit 101 executes the process when the person is within the stay detection range R2 again.
Here, the case where the same person has returned is described as an example, but the control unit 101 also returns “YES” in step 9 when another person has moved into the stay detection range R2. Is determined.

Next, registration of the standard processing by the user using the image forming apparatus 10 will be described.
FIG. 7 is a flowchart for explaining the procedure of the standard processing registration. The processing described below is basically executed by the control unit 101 and the routine processing unit 110 provided in the image forming apparatus 10.

  When the user requests the start of the routine processing registration via the user interface 13, the creating unit 111 causes the touch panel 130 provided on the user interface 13 to display a guidance screen for accepting various inputs regarding the routine processing registration. Then, the creation unit 111 accepts a setting related to the type of the standard processing via the user interface 13 (Step 21). In this example, the type accepted in step 21 is an example of the first process, and here is any of scan, print, copy, and facsimile.

  Next, the creation unit 111 accepts settings related to the parameters of the routine processing via the user interface 13 (Step 22). Here, the parameter is an example of the second processing or the third processing, and is associated with the type set in step 21. For example, in the case of copying, a color mode (color, black and white) is used as a parameter. , Reading resolution, document type (photo document, character document, character / photo document), and the like.

  Subsequently, the creating unit 111 receives an input relating to the name of the standard processing via the user interface 13 (Step 23). Here, the name is a name given by the user to the routine processing, and for example, a word or the like which briefly describes the contents of the routine processing may be adopted.

  Then, the creating unit 111 determines whether or not there is a registration instruction for the standard processing accepted in Steps 21 to 23 via the user interface 13 (Step 24). If a negative determination (NO) is made in step 24, the process returns to step 21 and continues.

  On the other hand, when an affirmative determination (YES) is made in step 24, the creating unit 111 creates a code image including the contents of the standard processing accepted in steps 21 to 23 as code information (step 25). Then, the creation unit 111 performs the routine processing using the type received in step 21, the parameter received in step 22, the name received in step 23, and the code information that is the source of the code image created in step 25. A table is created, and the obtained routine processing table is registered in the storage unit 112 (step 26). The details of the routine processing table will be described later.

  Subsequently, the creating unit 111 creates print data using the code image associated with the standard processing registered in the standard processing table in step 26 and the type and parameter contents associated with the code image. Then, the obtained print data is output to the printer 12 (image forming unit 107) (step 27). Then, the printer 12 that has received the print data forms an image on the recording material based on the print data, and outputs it as a code image recording sheet 50 (see FIG. 10 described later). Thus, a series of processing is completed.

  FIG. 8 is a diagram for explaining an example of a standard processing table created by the standard processing registration shown in FIG. This routine processing table is registered in the storage unit 112 (or the storage unit 105).

  The routine processing table of the present embodiment associates job IDs, names, types, parameters associated with the types, and code information on codes (large code and small code). Here, "type" is set in step 21 shown in FIG. 7, "parameter" is set in step 22 shown in FIG. 7, and "name" is set in step 23 shown in FIG. “Code information” is set in step 25 shown in FIG.

  First, the job ID is assigned by the image forming apparatus 10 for each routine processing. Here, four job IDs (“J0001” to “J0004”) are set. Note that, in this example, a case where four fixed processes are registered is described as an example. However, the number may be three or less, or five or more.

  Here, in the routine processing in which the job ID is set to “J0001”, the type is set to “copy”. In the standard processing of “J0001”, the parameters are “color mode: black and white, reading resolution: 600 dpi, document type: photo, input surface (when reading a document): one side, output surface (when an image is formed): both sides” , (At the time of image formation): 2 pages ". Further, in the standard processing of “J0001”, the name is set to “saving copy”.

  Next, in the standard processing in which the job ID is set to “J0002”, the type is set to “copy”. In the standard processing of “J0002”, parameters are set to “color mode: color, reading resolution: 600 dpi, document type: photograph, input side: both sides, output side: one side, number of pages per sheet: 1”. Have been. Furthermore, in the standard processing of “J0002”, the name is set to “color copy”.

  Subsequently, in the routine processing in which the job ID is set to “J0003”, the type is set to “facsimile (transmission)”. In the standard processing of “J0003”, the parameters are set to “color mode: black and white, reading resolution: 200 dpi, document type: character, input side: one side, destination: 03-XXXX-XXXX”. Further, in the standard processing of “J0003”, the name is set to “FAX order”.

  Finally, in the routine processing in which the job ID is set to “J0004”, the type is set to “scan”. In the standard processing of "J0004", the parameters are set to "color mode: black and white, reading resolution: 600 dpi, document type: text / photo, input side: one side, destination: \ test \ orderbackup". Further, in the standard processing of “J0004”, the name is set to “store order form”.

  Here, the standard processing of “J0001” and the standard processing of “J0002” are common in that the type is “copy”. However, these two standard processes differ in some contents of parameters (here, a color mode, an input surface, an output surface, and the number of pages per sheet).

  In addition, the fixed-type processing of “J0001” and “J0002”, the fixed-type processing of “J0003”, and the fixed-type processing of “J0004” have types of “copy”, “facsimile (transmission)”, and “scan”. Is different. Naturally, the contents of the parameters are different between these four routine processes.

Next, the code information associated with each routine processing will be described.
The code information in this example has large code information for forming a relatively large code image and small code information for forming a relatively small code image. In these examples, the large code information as an example of the first code includes information of a type in the routine processing, and the small code information as an example of the second code includes information of parameters in the routine processing. .

  Therefore, in the standard processing of “J0001” and the standard processing of “J0002” whose types are both set to “copy”, the large code information is set to “A” which is common. However, since the fixed process of “J0001” and the fixed process of “J0002” have different parameters, the small code information of the fixed process of “J0001” is “a1” and the small code information of the fixed process of “J0002” is small. The code information is set to “a2” different from “a1”.

  On the other hand, in the standard processing of “J0003” in which the type is set to “facsimile (transmission)”, large code information is set to “B” different from “copy”. Then, the small code information of the routine processing of “J0003” is set to “b” different from “a1” and “a2”.

  On the other hand, in the standard processing of “J0004” whose type is set to “scan”, large code information is set to “C” different from “copy” and “facsimile (transmission)”. Then, the small code information of the standard processing of “J0004” is set to “c” different from “a1”, “a2” and “b”.

FIG. 9 is a diagram for explaining the configuration of the code image 52 used in the first embodiment.
The code image 52 of the present embodiment has a square shape as a whole. Further, the code image 52 has information in the horizontal direction (horizontal direction) and the vertical direction (vertical direction) by arranging small square dots vertically and horizontally and filling one or more of these dots. It is composed of a two-dimensional code having

  The code image 52 according to the present embodiment has a large code recording area 521 for recording a code (large code) based on large code information and a small code area 521 for recording a code (small code) based on small code information. And a code recording area 522. The code image 52 is a composite two-dimensional code in which a small square code recording area 522 is arranged inside a large square code recording area 521. Here, in the present embodiment, the code image 52 has a function as an example of the first image and the second image, the large code recording area 521 is a recording area of the first image, and the small code The recording area 522 is a recording area for the second image.

  The code image 52 according to the present embodiment is configured by dividing the entire area having a square shape into 7 × 7 areas, and further dividing the 3 × 3 area located at the center thereof into 12 × 12 areas. Have been. Then, in the area divided into 7 × 7, the outer square-shaped area (40 dots) excluding the 3 × 3 area located at the center becomes the large code recording area 521, and the area 3 located at the center is obtained. A 12 × 12 area (144 dots) located in the × 3 area is the small code recording area 522. Here, one reference area (dot) in the large code recording area 521 is referred to as a large code reference area 521a, and one reference area (dot) in the small code recording area 522 is referred to as a small code reference area 522a. . In this example, “the area of the large code reference area 521a> the area of the small code reference area 522a”. Further, “the information amount of the large code recording area 521 <the information amount of the small code recording area 522” is satisfied. In the present embodiment, the size of the large code recording area 521 corresponds to the first size, and the size of the small code recording area 522 corresponds to the second size. Also, in the present embodiment, the area of the large code reference area 521a is the size of the unit cell forming the first image, and the area of the small code reference area 522a is the size of the unit cell forming the second image. Each corresponds.

  FIG. 10 is a diagram for explaining the configuration of the code image recording sheet 50 used in the first embodiment. The code image recording sheet 50 shown in FIG. 10 is output by the printer 12 in the registration of the standard processing shown in FIG.

  A code image recording sheet 50 as an example of a recording medium includes a sheet 51 as an example of a recording material or a medium, and a code image 52, a name image 53, and a parameter image formed on one surface (recording surface) of the sheet 51. 54. Here, the code image recording sheet 50 illustrated in FIG. 10 is created based on the standard processing to which the job ID “J0001” is assigned in the standard processing table illustrated in FIG.

  In this example, the code image 52 is composed of a composite two-dimensional code shown in FIG. Here, the code image 52 has a size occupying more than an upper half of the area of the sheet 51 of, for example, JIS4 size (vertical). In the large code recording area 521 (see FIG. 9) of the code image 52, a code (large code) including the large code information A (see FIG. 8) of the job ID “J0001” is recorded. A code (small code) including the small code information a1 (see FIG. 8) of the job ID “J0001” is recorded in the code recording area 522 (see FIG. 9).

  In the code image recording sheet 50 on which the code image 52 shown in FIG. 9 is recorded, the size of the large code reference area 521a of the large code recording area 521 and the small code reference area 522a of the small code recording area 522 are described above. Are different. Therefore, when the code image recording sheet 50 of the present embodiment is brought closer to the first camera 15, the recorded contents of the large code recording area 521 are read first, and the recorded contents of the small code recording area 522 are later read. Will be read. That is, due to the resolution of the first camera 15, the recorded content of the large code recording area 521 can be determined at a relatively distant position, and the recorded content of the small code recording area 522 can be determined at a relatively close position. It becomes possible.

  Here, when setting processing by manual input to the user interface 13 or the like without using the code image recording sheet 50 or the like, first, the type of the job is selected, and then various parameters relating to the selected type are selected. Will be selected. On the other hand, in the code image recording sheet 50 of the present embodiment, the type of the job which is a relatively higher layer is assigned to a relatively large code (large code recording area 521) in the code image 52. , A parameter that is a relatively lower layer is assigned to a relatively small code (small code recording area 522) in the code image. In the code image recording sheet 50 according to the present embodiment, as described above, the recorded contents of the large code recording area 521 are read first, and the recorded contents of the small code recording area 522 are read later. The device 10 first grasps the type of the job, and subsequently grasps the parameters (detailed settings) of this job.

  The name image 53 as an example of the first character image is arranged below the code image 52. The name image 53 is a name in which the name assigned to the standard processing is represented by characters, and in this example, a “saving copy” (see FIG. 8) which is the name of the job ID “J0001” is recorded.

  Further, the parameter image 54 as an example of the second character image is arranged below the name image 53. The parameter image 54 is a representation of various parameters set in the standard processing in characters. In this example, the parameter set in the job ID “J0001” is “Color mode: black and white. Reading resolution: 600 dpi. -Document type: Photo-Input side: One side-Output side: Both sides-Number of pages per sheet: 2 "(see Fig. 8) is recorded.

  Here, in the name image 53 and the parameter image 54, the characters are arranged so that the user can read them when the code image 52 is positioned above them. It should be noted that the name image 53 and the parameter image 54 are recorded on the code image recording sheet 50 in addition to the code image 52 because the user can grasp the contents of the corresponding standard processing only by looking at the code image 52. This is because it becomes substantially impossible.

  Next, the operation of the image forming apparatus 10 in the normal mode will be described. In the image forming apparatus 10 of the present embodiment, the first processing is executed in the normal mode, and the second processing is executed during the execution of the first processing (step 104 described later).

  FIG. 11 is a flowchart illustrating a flow of a first process related to the operation of the image forming apparatus 10 in the normal mode. The processing described below is basically executed by the control unit 101 and the routine processing unit 110 provided in the image forming apparatus 10.

  In the image forming apparatus 10 operating in the normal mode, the routine processing unit 110 analyzes a captured image (first camera image) acquired from the first camera 15. The routine processing unit 110 monitors the state of entry of the person into the stay detection range R2 (referred to as “stay detection range entry state”) based on the analysis result of the first camera image. However, initially, entry of a person into the stay detection range R2 is not detected (monitoring / not detected) (step 102).

  Next, the routine processing unit 110 determines whether or not the detection of the code image 52 recorded on the code image recording sheet 50 has been completed (whether or not the code has been detected) (step 104). If an affirmative determination (YES) is made in step 104, the routine processing section 110 executes the routine processing specified based on the reading of the code image 52 and the result (step 106), and completes the first processing. I do.

  On the other hand, if a negative determination (NO) is made in step 104, the routine processing section 110 determines whether or not the entry of a person into the stay detection range R2 has been detected (step 108). If a negative determination (NO) is made in step 108, the process returns to step 102 to continue the processing.

  On the other hand, if a positive determination (YES) is made in step 108, the routine processing unit 110 continuously monitors the stay detection range entry state. At this point, the entry of the person into the stay detection range R2 has been detected ( (Monitoring / detected) (step 110).

  Then, the control unit 101 displays, on the touch panel 130 provided on the user interface 13, a guidance screen (normal screen) set for a user who does not use the code image 52 (code image recording sheet 50). (Step 112), a series of processing is completed. Here, the normal screen displays a menu such as “copy”, “scan”, and “facsimile transmission”, for example, in order to receive an operation (selection of a job type and parameter setting related to the selected type) by a user. belongs to.

  FIGS. 12 and 13 are flowcharts showing the flow of a second process relating to the operation of the image forming apparatus 10 in the normal mode. Note that the processing described below is also basically executed by the control unit 101 and the routine processing unit 110 provided in the image forming apparatus 10. Here, the second process described below is executed in step 104 of FIG.

  In the image forming apparatus 10 operating in the normal mode, the routine processing unit 110 analyzes a captured image (first camera image) acquired from the first camera 15. Then, the routine processing unit 110 monitors the approach state of the person with respect to the approach detection range R1 (referred to as “approach detection state”) based on the analysis result of the first camera image. At this point, the entry of the person into the approach detection range R1 is detected (monitoring / detected) (step 202). In step 202, the routine processing unit 110 does not monitor the code image 52 based on the analysis result of the first camera image. Therefore, the detection state of the large code in the code image 52 is undetected (not monitored / not detected), and the detection state of the small code in the code image 52 is also not detected (not monitored / not detected).

  Subsequently, the routine processing unit 110 determines whether or not the approach of a person to the approach detection range R1 has been detected based on the monitoring result of the approach detection state (step 204). If a negative determination (NO) is made in step 204, the routine processing unit 110 sets the approach detection state to “monitoring / not detected”, sets the large code detection state to “not monitored / not detected”, and detects the small code. The status is set to “not monitored / not detected” (step 228), and the process returns to step 204 to continue.

  On the other hand, if an affirmative determination (YES) is made in step 204, the routine processing unit 110 traces (tracks) a person who has detected an approach to the approach detection range R1 and checks whether a code is presented by this person. Is monitored (step 206). Here, the code presentation by a person means that the person approaching the image forming apparatus 10 while holding the code image recording sheet 50 is the recording surface of the code image recording sheet 50 (the surface on which the code image 52 is formed). ) Is directed to the image forming apparatus 10 (first camera 15). Then, the routine processing unit 110 sets the approach detection state to “monitoring / detected”, sets the large code detection state to “monitoring / not detected”, and sets the small code detection state to “monitoring / not detected” ( Step 208).

  Along with this, the routine processing unit 110 causes the touch panel 130 provided on the user interface 13 to display a screen of “during code detection” meaning that the detection of the code image 52 has been started (step 210). Then, the routine processing unit 110 determines whether or not a large code has been detected based on the result of imaging by the first camera 15 (step 212). If a negative determination (NO) is made in step 212, the routine processing section 110 next determines whether or not a person is traced within the approach detection range R1 (step 230). If an affirmative determination (YES) is made in step 230, the process returns to step 210 and continues. On the other hand, if a negative determination (NO) is made in step 230, the process shifts to step 228 to continue the process.

  On the other hand, if a positive determination (YES) is made in step 212, the routine processing unit 110 analyzes the large code detected in step 212 (step 214). Subsequently, the routine processing unit 110 checks the contents of the large code obtained in step 214 with the contents of the routine processing table (see FIG. 8), and determines whether or not this large code is valid (the routine processing table). Is determined (step 216). If a negative determination (NO) is made in step 216, the routine processing unit 110 displays the “code” on the touch panel 130 provided on the user interface 13, which means that the large code is not registered in the image forming apparatus 10. "Detection error" is displayed (step 232), and the process proceeds to step 230 to continue the process.

  On the other hand, if a positive determination (YES) is made in step 216, the routine processing unit 110 sets the approach detection state to “monitoring / detected”, sets the large code detection state to “detected”, and sets the small code detection state to “detected”. Is "monitoring / not detected" (step 218). Then, the routine processing unit 110 determines whether or not a small code is detected based on the result of imaging by the first camera 15 (step 220). If a negative determination (NO) is made in step 220, the routine processing section 110 next determines whether or not a person is traced within the approach detection range R1 (step 234). If an affirmative determination (YES) is made in step 234, the process returns to step 218 and continues. On the other hand, if a negative determination (NO) is made in step 234, the process proceeds to step 228 to continue the processing.

  On the other hand, if a positive determination is made in step 220 (YES), the routine processing section 110 analyzes the small code detected in step 220 (step 222). Subsequently, the routine processing unit 110 compares the contents of the small code obtained in step 222 with the contents of the routine processing table (see FIG. 8), and determines whether the small code is valid (the routine processing table). Is determined (step 224). If a negative determination (NO) is made in step 224, the routine processing section 110 displays the “code” on the touch panel 130 provided on the user interface 13 indicating that the small code is not registered in the image forming apparatus 10. "Detection error" is displayed (step 236), and the process proceeds to step 234 to continue the process.

  On the other hand, if a positive determination (YES) is made in step 224, the routine processing unit 110 sets the approach detection state to “not monitored / detected”, the large code detection state to “not monitored / detected”, and The code detection state is set to "not monitored / detected" (step 226), and the second process is completed.

Now, the second process according to the present embodiment will be described with an example.
FIG. 14 is a diagram illustrating a temporal change in the position of a person H around the image forming apparatus 10 according to the first embodiment.

  First, FIG. 14A shows a state where the person H holding the code image recording sheet 50 has begun to approach the image forming apparatus 10. At this time, it is assumed that the person H faces the recording surface (the surface on which the code image 52 and the like are formed) of the code image recording sheet 50 shown in FIG. However, in the state shown in FIG. 14A, the person H exists in the detection range F but does not enter the approach detection range R1. Therefore, in the state shown in FIG. 14A, a negative determination (NO) is made in step 204.

  Next, FIG. 14B illustrates a state in which the person H holding the code image recording sheet 50 further approaches the image forming apparatus 10 from the position illustrated in FIG. At this time, the person H has entered the approach detection range R1 (not the stay detection range R2), and a positive determination (YES) is made in step 204. Further, in the state shown in FIG. 14B, the large code in the code image 52 recorded on the code image recording sheet 50 held by the person H based on the imaging result (first camera image) by the first camera 15 It is detected (YES in step 212). Here, in this example, the large code in the code image 52 is valid (YES in step 216). In this example, since the large code in the code image 52 indicates a copy (large code information: A), the image forming apparatus 10 starts preparations necessary for the copy operation from this point. Here, in the present embodiment, the positional relationship between the image forming apparatus 10 (first camera 15) and the code image recording sheet 50 (code image 52) shown in FIG. 14B corresponds to the first distance. I have.

  Subsequently, FIG. 14C illustrates a state in which the person H holding the code image recording sheet 50 further approaches the image forming apparatus 10 from the position illustrated in FIG. At this time, the person H continues to enter the approach detection range R1 (has not entered the stay detection range R2). Further, in the state shown in FIG. 14C, the small code in the code image 52 recorded on the code image recording sheet 50 held by the person H is based on the imaging result (first camera image) by the first camera 15. It is detected (YES in step 220). Here, in this example, the small code in the code image 52 is valid (YES in step 224). In this example, since the small code in the code image 52 corresponds to the job ID “J0001” (small code information: a1), the image forming apparatus 10 changes the job ID “J0001” from this point in time. The setting of the corresponding parameters (color mode: black and white, reading resolution: 600 dpi, document type: photograph, input side: one side, output side: both sides, number of pages per sheet: 2) is started. Here, in the present embodiment, the positional relationship between the image forming apparatus 10 (first camera 15) and the code image recording sheet 50 (code image 52) shown in FIG. 14C corresponds to the second distance. I have.

  FIG. 14D shows a state in which the person H holding the code image recording sheet 50 further approaches the image forming apparatus 10 from the position shown in FIG. At this time, the person H has entered the stay detection range R2 from the approach detection range R1 and is in a state where the user interface 13 can be operated (for example, a start button or the like is pressed). Here, in the present embodiment, for example, when the person H enters the stay detection range R2, the image forming apparatus 10 starts executing “saving copy”, which is the standard processing corresponding to the job ID “J0001”. You're ready to go. For this reason, the person H can start the target routine processing (here, saving copy) in the state shown in FIG. 14D.

  In the present embodiment, the composite type two-dimensional code is configured by providing the large code recording area 521 and the small code recording area 522 in one code image 52. However, the present invention is not limited to this. Absent. For example, as the code image 52, a two-dimensional code using a composite method as described in JP-A-2014-85777 may be used.

<Embodiment 2>
In the first embodiment, one code image 52 is a composite two-dimensional code. On the other hand, in the present embodiment, a plurality of code images having different sizes are used. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

FIG. 15 is a diagram for explaining the configuration of the code image 52 used in the second embodiment.
The code image 52 of the present embodiment also has a square shape as a whole. Further, the code image 52 has information in the horizontal direction (horizontal direction) and the vertical direction (vertical direction) by arranging small square dots vertically and horizontally and filling one or more of these dots. It is composed of a two-dimensional code having

  The code image 52 according to the present embodiment has a code recording area 523 for recording a code based on the code information. Unlike the first embodiment, the code image 52 is a non-composite two-dimensional code.

  The code image 52 of the present embodiment is configured by dividing the entire area having a square shape into 7 × 7 areas. Then, the entire area (49 dots) divided into 7 × 7 becomes a code recording area 523. Here, one area (dot) serving as a reference in the code recording area 523 is referred to as a code reference area 523a.

  FIG. 16 is a diagram for explaining the configuration of the code image recording sheet 50 used in the second embodiment. The code image recording sheet 50 shown in FIG. 16 is also output by the printer 12 in the routine processing registration shown in FIG.

  The code image recording sheet 50 of the present embodiment includes a sheet 51 and a large code image 61, a small code image 62, a name image 63, and a parameter image 64 formed on one surface (recording surface) of the sheet 51. Have. Among them, the small code image 62 includes a first small code image 621 and a second small code image 622, and the parameter image 64 includes a first parameter image 641 and a second parameter image 642. Here, the code image recording sheet 50 shown in FIG. 16 is also created based on the routine processing to which the job ID “J0001” is assigned in the routine processing table shown in FIG.

  In this example, the first small code image 621 and the second small code image 622 in the large code image 61 and the small code image 62 are each composed of a non-composite two-dimensional code (code image 52) shown in FIG. ing. Here, the large code image 61 has a size occupying at least an upper half area of the JIS A4 size (vertical) sheet 51, for example. On the other hand, the first small code image 621 and the second small code image 622 constituting the small code image 62 are arranged side by side below the large code image 61, and are each smaller than the large code image 61. It has a size. In this example, the first small code image 621 and the second small code image 622 have the same size. In the large code image 61, a code (large code) including the large code information A (see FIG. 8) of the job ID “J0001” is recorded. On the other hand, among the small code images 62, a part (small code) of the small code information a1 of the job ID “J0001” is recorded in the first small code image 621, and the second small code image 622 Indicates the remaining part (small code) of the small code information a1 of the job ID “J0001”. In this example, “the area of the large code image 61> the area of the first small code image 621 = the area of the second small code image 622”. Also, “the area of the code reference area 523a in the large code image 61> the area of the code reference area 523a in the first small code image 621 = the area of the code reference area 523a in the second small code image 622”. Further, “the information amount of the large code image 61> the information amount of the first small code image 621 = the information amount of the second small code image 622” is satisfied. Here, in the present embodiment, the large code image 61 is an example of the first image, and the first small code image 621 and the second small code image 622 constituting the small code image 62 are each an example of the second image. , Each is working. In the present embodiment, the area of the large code image 61 corresponds to the first size, and the area of the first small code image 621 or the area of the second small code image 622 corresponds to the second size. Further, in the present embodiment, the area of the code reference region 523a in the large code image 61 is determined by the size of the unit cell constituting the first image, the area of the first small code image 621 or the code in the second small code image 622. The area of the reference region 523a corresponds to the size of the unit cell constituting the second image.

  In the code image recording sheet 50 in which the code image 52 shown in FIG. 15 is recorded as one large code image 61 and two small code images 62, the code image reference area 523a in the large code image 61 and the code image in the small code image 62 The size differs from the reference area 523a. Therefore, when the code image recording sheet 50 of the present embodiment is brought closer to the first camera 15, the recorded content of the large code image 61 is read first, and then the recorded content of the small code image 62 is read. Will be. That is, the recorded content of the large code image 61 can be determined at a relatively distant position and the recorded content of the small code image 62 can be determined at a relatively close position due to the resolution of the first camera 15. Become.

  Here, when setting processing by manual input to the user interface 13 or the like without using the code image recording sheet 50 or the like, first, the type of the job is selected, and then various parameters relating to the selected type are selected. Will be selected. On the other hand, in the code image recording sheet 50 according to the present embodiment, the large code image 61 in which the job type of the relatively higher hierarchy is relatively large is allocated to the relatively lower hierarchy. The parameters are assigned to the small code image 62 having relatively small parameters. In the code image recording sheet 50 of the present embodiment, as described above, the recorded content of the large code image 61 is read first, and the recorded content of the small code image 62 is read later, so that the image forming apparatus 10 First, the type of the job is grasped, and then the parameters (detailed settings) of this job are grasped.

  The name image 63 as an example of the first character image is arranged below the large code image 61 and above the small code image 62. The name image 63 is a name in which the name given to the standard processing is expressed in characters, and in this example, a "saving copy" (see FIG. 8) which is the name of the job ID "J0001" is recorded.

  Further, in the parameter image 64 as an example of the second character image, the first parameter image 641 is arranged below the first small code image 621, and the second parameter image 642 is arranged below the second small code image 622. Have been. The parameter image 64 is a representation of various parameters set for the corresponding routine processing in characters. In this example, as the first parameter image 641, a part of the parameters set to the job ID “J0001” is “color mode: black and white, reading resolution: 600 dpi, document type: photograph” (see FIG. 8). Is recorded. Further, in this example, the second parameter image 642 is the remaining part of the parameters set to the job ID “J0001”, which is “input side: one side, output side: both sides, number of pages per sheet: 2 (See FIG. 8). Note that the first small code image 621 includes “• color mode: black and white • reading resolution: 600 dpi • document type: photograph” as a code, and the second small code image 622 includes “• input surface: one side” as a code. -Output side: Both sides-Number of pages per sheet: 2 "is included.

  Here, characters are arranged in the name image 63 and the parameter image 64 so that the user can read the large code image 61 when the large image 61 is positioned above them. In this example, the small code image 62 is composed of two images, but the number of the small code images 62 may be one or three or more.

  Also when the image forming apparatus 10 of the present embodiment operates, the first processing shown in FIG. 11 and the second processing shown in FIGS. 12 and 13 are performed as in the first embodiment. However, in the first embodiment, the routine processing unit 110 extracts a large code and a small code from the first camera image captured by the first camera 15. On the other hand, in the present embodiment, the large code is extracted from the first camera image captured by the first camera 15 and the small code is extracted from the second camera image captured by the second camera 16.

Now, the second process according to the present embodiment will be described with an example.
FIG. 17 is a diagram illustrating a temporal change in the position of the person H around the image forming apparatus 10 according to the second embodiment.

  First, FIG. 17A shows a state where the person H holding the code image recording sheet 50 has begun to approach the image forming apparatus 10. At this time, it is assumed that the person H faces the recording surface (the surface on which the large code image 61 and the like are formed) of the code image recording sheet 50 shown in FIG. However, in the state shown in FIG. 17A, the person H exists in the detection range F but does not enter the approach detection range R1. Therefore, in the state shown in FIG. 17A, a negative determination (NO) is made in step 212.

  Next, FIG. 17B illustrates a state in which the person H holding the code image recording sheet 50 has further approached the image forming apparatus 10 from the position illustrated in FIG. At this time, the person H has entered the approach detection range R1 (not the stay detection range R2), and a positive determination (YES) is made in step 204. In the state shown in FIG. 17B, the large code in the large code image 61 recorded on the code image recording sheet 50 held by the person H based on the imaging result (first camera image) by the first camera 15 Is detected (YES in step 212). Here, in this example, the large code in the large code image 61 is valid (YES in step 216). In this example, since the large code in the large code image 61 means copy (large code information: A), the image forming apparatus 10 starts preparations necessary for the copy operation from this point. . Here, in the present embodiment, the positional relationship between image forming apparatus 10 (first camera 15) and code image recording sheet 50 (large code image 61) shown in FIG. 17B corresponds to the first distance. ing.

  Subsequently, FIG. 17C illustrates a state in which the person H holding the code image recording sheet 50 further approaches the image forming apparatus 10 from the position illustrated in FIG. At this time, the person H has entered the stay detection range R2 from the approach detection range R1 and is in a state where the user interface 13 can be operated (for example, a start button or the like is pressed). In this state, the person H holds the code image recording sheet 50 held by the user H over the user interface 13. At this time, the person H causes the recording surface of the code image recording sheet 50 to face the user interface 13, and the small code image 62 (the first small code image 621 and the second small code image 621) formed on the code image recording sheet 50. The code image 622) is sequentially directed to the second camera 16. Then, in the state shown in FIG. 17C, based on the imaging result (second camera image) by the second camera 16, the small code image 62 (the first small code image 621 and the small code image 621) recorded on the code image recording sheet 50 is obtained. Second small code image 622) is detected (YES in step 220). Here, in this example, the small code in the small code image 62 is valid (YES in step 224). In this example, since the small code in the small code image 62 corresponds to the job ID “J0001” (small code information: a1), the image forming apparatus 10 starts the job ID “J0001” from this point. (Color mode: black and white, reading resolution: 600 dpi, document type: photograph, input side: one side, output side: both sides, number of pages per sheet: 2) are started. Here, in the present embodiment, the positional relationship between the image forming apparatus 10 (second camera 16) and the code image recording sheet 50 (small code image 62) shown in FIG. 17C corresponds to the second distance. ing.

  FIG. 17D shows a state in which the person H holding the code image recording sheet 50 stays at the position shown in FIG. 17C. At this time, the person H is present in the stay detection range R2, and is in a state where the user interface 13 can be operated. At this time, the person H is again holding the code image recording sheet 50 held over the second camera 16 provided on the user interface 13. Here, in the present embodiment, during the transition from the state illustrated in FIG. 17C to the state illustrated in FIG. 17D, the image forming apparatus 10 performs the routine processing corresponding to the job ID “J0001”. The preparation for starting the execution of a certain "saving copy" has been completed. Therefore, the person H can start the target routine processing (saving copy in this case) in the state shown in FIG. 17D.

  In the present embodiment, as shown in FIG. 16, the first small code image 621 and the second small code image 622 constituting the small code image 62 are set for the routine processing of the same job ID.
