Description

  The present invention relates to an image forming apparatus including a lottery system that forms an image on transfer paper based on image data.

  2. Description of the Related Art Conventionally, there are image forming apparatuses that form an image of a document read by a scanner or the like on a transfer sheet, for example, a copying machine, a multifunction machine, and the like.

  In general, a copying machine and a multifunction peripheral are provided in the form of lease from the manufacturer side that performs sales and maintenance management to the user side, or in the form of sales purchased by the user side. The manufacturer not only provides the main body of copiers and multifunction machines, but also provides maintenance management services such as inspection, repair and adjustment of the copiers and multifunction machines provided.

  The above-mentioned maintenance management service fee is based on the number of times the copy is used, and is calculated at a unit price per sheet. For this reason, the copier or multifunction machine provided is usually provided with a counter. Thereby, the manufacturer side calculates the maintenance management service fee by counting the number of copies used in a predetermined period, for example, one month.

  On the other hand, copying machines and multi-function machines are now installed in convenience stores, etc., which perform formation (printing) for the number of sheets instructed by the user and collect a fee according to the number of sheets formed by the user. ing.

  However, with regard to the maintenance management service fee, there are currently many services that reduce the copy unit price if the number of copies used by the user exceeds a certain value. No service is available. Also, copiers and multifunction machines installed in convenience stores and the like simply provide image forming services, but do not provide services that have the effect of attracting customers.

Therefore, Patent Document 1 receives, registers, and registers a lottery number of a sheet when a printer that stores a plurality of sheets and can attach and detach a media pack that holds a plurality of lottery number information performs printing. It is described that a lottery system for drawing lottery numbers and notifying the lottery results allows the user to receive a winning prize by lottery or receive a service for purchasing printer consumables with the winning prize.
JP2002-133023

  In the lottery system disclosed in Patent Document 1, the user cannot participate in the lottery system unless a transfer sheet in which a lottery number is stored in advance is used. Therefore, use the backing paper that is commonly used in current offices (use the back side of the transfer paper once copied as copy paper again), or use inexpensive transfer paper other than the one specified by the manufacturer. In such a case, since the user cannot participate in the lottery system, the user's willingness to draw may be reduced. Further, since all lot numbers written on each transfer sheet are read, registered in the database, and lottery is performed, there is a concern that the control becomes very complicated.

  Accordingly, the present invention provides services suitable for individual users, or has the effect of attracting customers of copy users such as convenience stores, and improves the user or copy user's willingness to draw, and sells the image forming apparatus main body. It is an object of the present invention to provide an image forming apparatus equipped with a lottery system that leads to promotion and sales promotion of consumables such as toner.

  An image forming apparatus of the present invention forms an image on a transfer sheet based on image data, forms an image on the transfer sheet based on image data, and counts the number of image forming operations by the image forming unit. A soft counter means for electrically storing the value, a count value judging means for judging whether or not the count value of the soft counter means is a predetermined value, and making a winning / losing decision based on the judgment of the count value judging means A lottery means, an operation detecting means for detecting execution of an image forming operation by the image forming means, and the lottery means for performing a lottery when the operation detecting means detects execution of the image forming operation of the image forming means. And a control means for making it possible.

  In addition, when the operation detecting unit detects the execution of the image forming operation of the image forming unit, the control unit causes the lottery unit to execute the lottery and then executes the lottery again. It is preferable to determine using a random number table having execution probabilities.

  Further, the lottery means preferably has a plurality of random number tables having predetermined different lottery execution probabilities, and the random number table to be used is preferably made different according to image forming conditions by the image forming means. More preferably, the forming condition is the number of image forming operations, the number of transfer sheets on which images are formed, the size of transfer sheets on which images are formed, or color / monochrome image formation.

  An image forming apparatus according to the present invention includes: a count value determining unit that determines whether or not a count value of a soft counter unit is a predetermined value; a lottery unit that determines whether a win or a loss is made based on the determination of the count value determining unit; An operation detecting means for detecting the execution of the image forming operation by the means, and a control means for causing the lottery means to execute a lottery when the operation detecting means detects the execution of the image forming operation of the image forming means. A person can participate in the lottery system simply by copying. For this reason, the user's willingness to draw is improved, which leads to sales promotion of the image forming apparatus main body and sales promotion of consumables such as toner, and also has an effect of attracting a copy user at a convenience store or the like.

  Furthermore, an image forming apparatus provided with a lottery system can be provided by simple control of determining whether or not the count value of the soft count means originally provided in the image forming apparatus main body is a predetermined value.

  Preferably, when the operation detecting unit detects the execution of the image forming operation of the image forming unit, the control unit causes the lottery unit to execute the lottery and then executes the lottery again with a predetermined lottery execution probability. For example, even though a copier equipped with an automatic document feeder is used, a plurality of copies are intentionally divided into several times and selected. It is possible to prevent fraud that increases the probability.

  The lottery means preferably includes a plurality of random number tables having predetermined different lottery execution probabilities, and the random number table to be used is preferably made different according to the image forming conditions by the image forming means. More preferably, the number of times of image forming operation, the number of transfer sheets on which image formation has been performed, the size of transfer sheet on which image formation has been performed, or color / monochrome image formation is more preferable.

  For this reason, for example, the number of copies from when the user performs lottery after copying until the next lottery can be performed is determined randomly by a random number table, and there are a plurality of random number tables, and the number of transfer sheets on which images are formed. Or a random number table that differs depending on the image forming conditions such as the size of the transfer paper on which the image is formed or color / monochrome image formation, and the number of copies until the next lottery can be made is completely impossible to predict. This makes it possible to prevent unauthorized fraud, and allows the manufacturer to set the user's lottery frequency in accordance with the degree of consumption of consumables such as toner, thereby ensuring sufficient profits.

  Embodiments according to the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view schematically showing an internal configuration of a quadruple tandem type digital full-color multifunction peripheral 1 as an example of an image forming apparatus according to an embodiment of the present invention.

  As main components of the multifunction machine 1, 2 is a housing, 3B, 3Y, 3C, and 3M are image forming units for black, yellow, cyan, and magenta, respectively. 10B, 10Y, 10C, and 10M are the above-described colors. 12 is a paper feed cassette for storing transfer paper 14 as a recording medium, 13 is a paper feed guide, 11a and 11b are transport belt driving rollers, 8 is a transport belt, 9 is a transfer roller, and 17 is fixing. , 15 is a paper discharge guide, and 16 is a paper discharge section. The image forming units 3B, 3Y, 3C, and 3M for each color include a developing device 4, a photosensitive drum 5, a main charger 6, an LED array exposure device 7, a cleaning unit 20, and the like.

  In the multi-function device 1, an electrostatic latent image is formed by the LED array exposure device 7 on the photoreceptor 5 charged by the main charger 6, and developed by the developing device 4 to form a visible image. Such a process is performed for each color. The transfer paper 14 fed from the paper feed cassette 12 is guided by a paper feed guide and is attracted to the upper surface of the conveyor belt 8 rotating in the counterclockwise direction in the drawing, and the image forming units 3B, 3Y for each color. When passing directly below 3C and 3M, the image of each color is sequentially transferred onto the transfer paper 14 by the transfer roller 9. The four-color toners that form a full-color image on the transfer paper 14 in this way are fixed when the paper 14 passes through the fixing unit 17. Thereafter, the transfer paper 14 is guided to the paper discharge unit 16 by the paper discharge guide 15.

  When performing a printer operation, image data is input from an external computer or the like to a printer controller (described later) in the multifunction device 1, and the modulation signal generated based on the image data is converted into laser light by the LED array exposure device 7. Then, the image is output to the photosensitive drum 5, and an electrostatic latent image is formed on the photosensitive drum 5. Thereafter, development, transfer, fixing, and transfer paper conveyance similar to the copy operation are performed.

  FIG. 2 is a functional block diagram showing an outline of the electrical configuration of the multifunction machine 1. The multifunction machine 1 includes a control unit 100 that controls the operation of the entire apparatus.

  The control unit 100 includes a scanner unit 51 capable of reading a document image including an exposure lamp 511 and a CCD 512, a toner image forming unit 111 including a transfer paper transport unit 110, a photosensitive drum 5, a developing device 4, and the like, a transfer unit, and the like. An image forming unit (image forming unit) 140 composed of the roller 9, the fixing unit 17 and the like, and a counter unit (soft counter unit) 300 that electrically stores the number of image forming operations by the image forming hand unit 140 as a count value. And are connected.

  Connected to the control unit 100 is an image memory 150 used as a work area for temporarily storing document data read by the scanner unit 51 and an HDD (internal storage device) 150 capable of storing document data. Has been. The image processing unit 160 performs image processing necessary for image formation on the image data read by the scanner unit 51.

  The operation unit 47 is controlled by the control unit 100. The operation key unit 470 is a general term for a start key 471, a numeric keypad 472, a reset key 474, a stop key 475, a function switching key 477, and the like.

  The control unit 100 also functions as a scanner controller 101, a facsimile controller 102, a printer controller 103, a copy controller 104, and a network controller 105 that control each function that can be executed by the multifunction device 1.

  The scanner controller 101 performs operation control of each unit necessary for the operation of the scanner unit 51.

  The facsimile controller 102 controls the operation of each unit necessary for the facsimile operation, and controls the facsimile communication unit 121 that adjusts data necessary for facsimile communication. The facsimile communication unit 121 includes an NCU (Network Control Unit) that controls connection of a telephone line with a destination facsimile that is a data transmission / reception partner.

  The printer controller 103 performs operation control of each unit necessary for printer operation. The printer controller 103 includes a parallel I / F (Interface) unit 122 that is connected to an external device by parallel transmission that transmits several bits at once using a plurality of signal lines, and a single signal line. A serial I / F unit 123 connected to an external device is connected by serial transmission that sequentially transmits data bit by bit.

  The copy controller 104 controls the operation of each unit necessary for the copy operation.

  The network controller 105 controls data transmission / reception performed between the multifunction machine 1 and a computer on the network. The network controller 105 transmits / receives data to / from the outside via the network I / F unit 124.

  Furthermore, the control unit 100 includes an operation detection unit (operation detection unit) 106 that detects execution of an image forming operation (for example, start or end of an image forming operation) by the image forming unit 140, and the count value of the counter unit is a predetermined value. A count value determination unit (count value determination unit) 107 for determining whether or not, a lottery unit (lottery unit) 108 for determining whether to win or lose based on the determination of the count value determination unit 107, and an e-mail transmission / reception operation via a network It functions as an e-mail transmission unit 109 that controls the above.

  The lottery unit 108 determines whether to win or lose based on whether the count value determined by the count value determination unit 107 is a predetermined value. Predetermined values include numbers that have a count value (111, 222, 555, 888, 999, 3333,...), Delimiters (100, 200, 500, 800, 900, 3000,...), Etc. Can be set arbitrarily. Further, the narrower the predetermined value interval, the higher the winning probability, and the wider the predetermined value interval, the lower the winning probability.

  In addition, since the determination of winning or losing is determined by the numerical value of the counter unit (soft counter means) 300 built in the multifunction device 1, a special transfer in which a lottery number is stored in advance as in Patent Document 1. Even if paper is not used, the user can participate in the lottery system, so that the willingness to draw does not decrease, and the control of the multifunction device 1 does not become complicated.

  Further, the lottery unit 108 uses the random number table stored in the lottery data storage unit 170 to calculate the number of image forming operations by the image forming unit 140 until the lottery is executed again after the lottery is executed. It is preferable to determine.

  The lottery data storage unit 170 stores a plurality of different random number tables determined in advance according to the image forming conditions performed by the image forming unit 140, and is associated with the image forming conditions by the image forming unit 140. It is preferable that the random number table is selected by the lottery unit 108.

  Based on the user ID information input from the user to the operation unit 47, the e-mail transmission / reception unit 109 reads the e-mail address unique to each user stored in the e-mail transmission information storage unit 180 in association therewith, It is possible to transmit document data indicating winning or unsuccessful reading read from the mail transmission information storage unit 180.

  The image data storage unit 190 stores image data for expressing the lottery result by the lottery unit 108. When the lottery unit 108 performs the lottery, the control unit 100 stores the image data from the image data storage unit 190. It is possible to perform control such as reading image data suitable for the lottery result and causing the image forming unit 140 to print on transfer paper or to display on the display unit 473.

  The fee collection device 200 is provided when the multifunction device 1 is installed in a convenience store or the like, and is a coin vendor or the like externally connected to the multifunction device 1 and is controlled by the control unit 100.

  Next, a process when the image forming process and the lottery process are performed in the multifunction machine 1 will be described. FIG. 3 is a flowchart showing processing when image formation and lottery is performed in the multifunction device 1, FIG. 4 is a diagram showing an example of the operation unit 47 when winning is determined, and FIG. 5 is a diagram showing a state where a winning result is printed. It is.

  The multifunction device 1 performs image forming operations such as copying a document by a copy function, printing data stored in a database on an external network by a printer function, sending / receiving data by a facsimile function, etc. In such a case, it is determined whether or not the count value is a predetermined value, and a lottery is performed.

  It is assumed that the end of image formation by the image forming unit 140 is detected by the operation detecting unit 106 by executing the above copying and the lottery is executed by the lottery unit 108 (S1).

  Thereafter, when the operation detection unit 106 detects the end of the image formation by the image forming unit 140 by executing copying or the like (“Yes” in S2), the image formation after the last lottery is executed by the image formation. The control unit 100 confirms the image forming conditions until the current image formation (including the image forming conditions for the current image formation) (S3). The image forming conditions include, for example, the number of image forming operations performed between the image formation in which the previous lottery was executed and the current image formation, the number of transfer sheets on which the image was formed, or the transfer on which the image was formed. These are various conditions such as paper size or color / monochrome image formation. These conditions can be used alone or in combination of two or more.

  Then, the lottery unit 108 selects the random number table having the lottery execution probability corresponding to the confirmed image forming condition from the lottery data storage unit 170 (S4). Then, using the selected random number table, the lottery unit 108 determines whether or not to execute the lottery (S5).

  For example, when the number of transfer sheets on which image formation has been performed from the image formation after the previous lottery execution by image formation to the current image formation is greater than 50, for example, the lottery execution probability If an 80% random number table is used and the number of transfer sheets on which images are formed is 5 or more and 50 or less, a random number table having a lottery execution probability of 40% is used and the number of transfer sheets on which images are formed is 5 If the number is less than the number, control is performed using a random number table with a lottery execution probability of 5%.

  Here, when the number of transfer sheets on which an image is formed is less than 5, the very small value of the lottery execution probability is set to 5%, for example, copying with an automatic document feeder (ADF). Despite the use of the machine, 10 copies were intentionally divided into several copies (1st: 4 copies, 2nd: 3 copies, 3rd: 3 copies), lottery It is possible to increase the execution probability and prevent fraud that makes it easy to win. In addition, since the image forming conditions such as the number of transfer sheets have a positive correlation with the consumption level of consumables such as toner, it is possible for the manufacturer to set the user's lottery frequency according to the consumption level. Profit can be secured.

  On the other hand, in a copier not equipped with an ADF, it seems that the lottery execution probability always decreases when the number of copies per sheet is less than five. However, in the present invention, the control unit 100 checks the number of copies between the image formation in which the previous lottery was executed and the current image formation, and has a lottery execution probability corresponding to the number of copies. A major feature is the use of a random number table. Therefore, in actuality, even if the number of copies this time is less than five, the case where the previous number of copies is less than five by chance continues and the case where the lottery is not executed continues. Since the number of copies is also accumulated and determined, the lottery execution probability may increase. For this reason, since the chance of lottery execution is also largely controlled by chance, the user's willingness to draw increases.

  When two or more of the above image forming conditions are combined, for example, the entire transfer in which the number of images formed on a large size transfer paper such as A3 size is formed between the previous image formation and the current image formation. When it is 10% or more of the number of sheets, or when the number of full-color images formed on the transfer sheet between the previous image formation and the current image formation is 7% or more of the total number of transfer sheets on which the image is formed, It is better to set to increase the lottery execution probability.

  Thereafter, the control unit 100 reads out image data corresponding to the lottery result determined in S6 from the image data storage unit 190, and causes the display unit 473 to display the image data as the lottery result (S6). For example, if the lottery result is a win, image data indicating that the lottery has been won is read out, and a win result screen 4730 is displayed on the display unit 473 as shown in FIG. Recognize that is a winner. On the winning result screen 4730, a print button 4731 and a present unnecessary button 4732 are displayed.

  When the user presses the print button 4731 on the winning result screen 4730 and inputs a print instruction (“Yes” in S7), for example, the control unit displays an image formation result as shown in FIG. 100 causes the image forming unit 140 to print the winning result on the transfer sheet (S8). In this case, an image different from the winning result screen 4730 as shown in FIG. 5 may be printed on the transfer paper, or the winning result screen 4730 displayed on the display unit 473 may be directly printed on the transfer paper. Also good.

  In particular, as shown in FIG. 5, when the winning result is printed on the transfer paper, it is preferable to display the total copy count such as “Total copy count: 1000 sheets”. As a result, the cashier can have evidence that the Total copy count has redeemed 1000 presents. For example, after copying the voucher in advance and redeeming the present, It is possible to prevent fraud such as redeeming a present again using the exchange ticket that has been prepared.

  When there is no print instruction, for example, when the present unnecessary button 4732 is pressed or when there is no print instruction within a predetermined time (“No” in S7), the control unit 100 sets the image forming unit. The process is terminated without causing 140 to print the winning result. Therefore, if the user does not want to exchange prizes by winning, the user can select not to receive prizes by selecting not to print.

  In addition, a specific present product (for example, “one canned coffee”) may be displayed on the winning result screen 4730 displayed on the display unit 473, and it becomes easy to determine whether the present of the user is necessary or not.

  According to the processing of the first embodiment described above, the user prints the winning result on the transfer paper, so that a third party other than the user can easily confirm the winning result. Therefore, it is preferably implemented when the copying machine 1 is installed in a convenience store or the like.

  Next, a second embodiment of image forming processing and lottery processing by the multifunction machine 1 will be described. FIG. 6 is a flowchart illustrating a second embodiment of the image forming process and the lottery process performed by the multifunction machine 1. The second embodiment is characterized in that the lottery result by the lottery unit 108 is transmitted by e-mail to the user's mail address, and the description of the same parts as those in the first embodiment is omitted.

When the next image formation is completed after the lottery is completed (“Yes” in S12), the control unit 100 reads out image data for displaying a message for prompting input of user ID information from the image data storage unit 190. It is displayed on the display unit 473 (S13). When user ID information is input from the operation unit 47 by the user (“Yes” in S14),
In the same manner as in the first embodiment, it is determined whether or not lottery is executed (S17).

  When the user ID is not input by the user (“No” in S14), the process is terminated without performing the lottery by the lottery unit 108 and the mail transmission process described below.

  Subsequently, the e-mail transmission / reception unit 109 associates the user ID input from the operation unit 47 with the user's e-mail address (e-mail transmission destination) stored in the e-mail transmission information storage unit 180 and the winning selection. The document data indicating another is read (S18), and an e-mail having contents indicating the lottery result is transmitted to the e-mail address via the network controller 105 and the network I / F unit 124 (S19).

  According to the processing according to the second embodiment, since the lottery result is transmitted from the multifunction device 1 to the user by e-mail, even if the user moves to a place away from the multifunction device 1 after printing, The user can know the lottery result using a personal digital assistant (PDA), a mobile phone, a personal computer, or the like. In addition, since the lottery and the mail transmission are not performed unless the user inputs the user ID in the process of S13, the user selects whether to perform the lottery by selecting whether to input the user ID. You can choose.

  Next, a third embodiment of image forming processing and lottery processing by the multifunction machine 1 will be described. FIG. 7 is a flowchart illustrating a third embodiment of the image forming process and the lottery process performed by the multifunction machine 1. The third embodiment is characterized in that when winning is determined by a lottery process by the lottery unit 107, a process for reducing the print fee collected from the user is performed, and the description of the same parts as those in the first embodiment is omitted. .

  In the same manner as in the first embodiment, after image formation, it is determined whether or not lottery is executed (S25), lottery processing is performed after image formation, and the lottery result is displayed on the display unit 473 (S26). Here, if the lottery result is a win (“Yes” in S27), the copy fee to be collected from the user by the fee collection device 200 is determined from the regular fee calculated according to the printing conditions such as the total number of copies. Is processed to reduce the amount (S28). For example, processing such as discounting the regular fee at a predetermined rate (30% discount or the like) or subtracting a certain amount from the regular fee is performed. If the lottery result is a loss (“No” in S27), the control unit 100 does not perform the reduction process. Thereafter, the control unit 100 causes the fee collection device 200 to collect a fee corresponding to the lottery result (S29).

  According to the processing of the third embodiment, since the service of reducing the copy fee can be provided to the user simultaneously with the fee collection, it is preferably implemented particularly when the copying machine 1 is installed in a convenience store or the like. Further, since the user only needs to pay the reduced fee when collecting the fee by the fee collecting device 200, the economic burden on the user can be reduced and the effect of attracting customers can be expected.

  In addition, this invention is not restricted to the structure described in the said Embodiment 1-3, A various deformation | transformation is possible. For example, in the above embodiment, the random number table is used for the lottery process by the lottery unit 108, but other lottery processes such as a lottery process using a mathematical formula or the like may be performed.

  Further, when the combination of the first embodiment and the third embodiment is won by a lottery process, the user determines whether the service is to receive a present by performing a printing process or to reduce the copy fee. You may be able to choose.

  In the above-described embodiment, the full-color multifunction peripheral 1 is used as the image forming apparatus according to the present invention. However, the image forming apparatus has a copy function, a printer function, a fax function, or two or more functions. Of course there may be.
