Description

Automatic document feeder, control method, and multifunction device

Technical Field

The present invention relates to an automatic document feeder, a control method, and a multifunction device, and more particularly, to an automatic document feeder, a control method, and a multifunction device for feeding tickets.

Background

Existing copy machines operate by placing a ticket on a glass document surface, for example, when copying taxi tickets or shop receipts. As shown in fig. 1, for example, the copying machine mainly includes a document table cover 1, a document table 2, and an image forming apparatus main body 3. When copying or scanning the receipt 4, the operator places the receipt 4 at a predetermined position on the document table 2, and covers the document table cover 1 to perform the copying operation.

However, in the actual use process, the states of the tickets are various according to different requirements of customers, such as the size of the tickets, the thickness of the paper, the warping degree and the like. When the slip is thin or has a large warping degree, the slip to be copied needs to be placed on the document table, and when the cover plate is closed, the slip is generally displaced due to the wind, for example, from a predetermined position shown by a solid line to a position shown by a broken line in fig. 1, so that the copied image is inclined, and it is difficult to manually copy the image.

When the original document carrying device is used, since the size and shape, the thickness of the paper, the paper type, and the like of the receipt are different from those of the ordinary original document, there is a possibility that the receipt itself is not carried properly or damaged by using the uniform carrying conditions.

In the prior art, a scheme is proposed in which a receipt is placed in a specific film and then the receipt and the film are placed on a copying machine together for copying. However, this technique is cumbersome and time consuming to operate.

Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Further, it will be apparent to those skilled in the art that many alternatives thereof are possible in light of the above disclosure, and that the present invention is not limited to the preferred embodiments described herein.

< receipt conveyance control >

< first embodiment >

The following describes in detail the ticket conveyance control with reference to fig. 16 and 17. Note that, hereinafter, the ticket type information may be simply referred to as ticket information.

Fig. 16 is a flowchart of the slip transport control. As shown in fig. 16, in the ticket transport control, 5 steps of entering the ticket mode (step S01), acquiring the ticket type information (step S02), reading the transport conditions (step S03), transporting (step S04), and ending (step S05) are mainly performed in this order.

In step S01, a "ticket mode" button is provided on the operation panel, and the user enters the "ticket mode" after pressing the "ticket mode" button; in step S02, the ticket information may be acquired by user input or automatic recognition of the ticket information; in step S03, the copier reads the ticket transport conditions (as shown in fig. 22) based on the relationship between the ticket type information and the transport conditions stored in the storage unit; in step S04, the copier transports the slip according to the transport conditions, for example, if the slip is a value added tax slip, the speed V3 is selected to transport the slip from the slip supply unit to the slip discharge unit; in step S05, the slip conveyance is ended.

This will be described in detail with reference to fig. 17. In step S101, a "ticket mode" button is provided on the operation panel, and the user enters the "ticket mode" after pressing the "ticket mode" button (step S101) (step S102), and if the ticket supply unit is a separate unit, the ticket supply station on the automatic document feeder is automatically opened, and if the ticket supply unit and the document supply unit are shared, this step can be skipped, and a ticket type selection prompt, for example, an operation panel interface of the "ticket mode" shown in fig. 19 appears on the operation panel (step S103).

The user selects a prompt according to the type of the receipt, for exampleAs shown in the operation panel interface of "ticket mode" shown in fig. 19, whether the ticket information is manually input or the ticket type information is automatically recognized is selected. Note that the tip note type selection presentation may include only simple tip note information such as a bus note, a taxi note, a high-speed rail (blue note), a high-speed rail (powder note), an airplane note, a shopping invoice, a quota invoice, and a value-added tax invoice as shown in fig. 19, or may include a transport speed (e.g., 52 to 59 g/m) as shown in fig. 17²、60～90g/m²、90～120g/m²) Paper type and examples (e.g. tissue: value-added tax invoice, subway invoice, bus invoice, etc.; plain paper: copying bills, quota invoices, high-speed rails (powder tickets), notes, taxi tickets, shopping invoices and the like by using common paper of a copying machine; and (3) thick paper: postcards, photographs, high-speed rails (blue tickets), business cards, japanese electric tickets, hard tags, airline tickets, and the like; mixed paper) and the like.

For the selected type information of the tickets, the number of sheets (for example, thin paper × + plain paper × + thick paper ×) is set in order (step S104), the operation mode (for example, copying (combination copying on one sheet of paper or one sheet of paper copying), scanning (combination into one pdf or one pdf for one ticket), copying and scanning (combination copying on one sheet of paper while combination into one pdf or one ticket of paper copying while one pdf)) is selected (step S105), and the conveyance condition is selected.

In step S106, the copying machine conveys the tickets with the conveying speed changed according to the user selection (for example, thick paper: paper feed conveying roller speed V1, plain paper: paper feed conveying roller speed V2, thin paper: paper feed conveying roller speed V3, mixed paper: automatic change of paper feed conveying roller speed according to the number of each type of paper) (step S106). The acquisition slip type information step S02 will be described in detail below with reference to fig. 18. Fig. 18 is a flowchart of the step of acquiring the ticket kind information. As shown in fig. 18, the step of acquiring the type information of the tickets mainly includes the following steps:

in step S021, it is determined whether or not user input is required, and if the determination result is yes, the process proceeds to step S022, and if the determination result is no, the slip information is automatically recognized from the information detected by the detection unit (step S028), and the conveyance condition is read (step S03).

In step S022, it is determined whether or not the ticket information is stored in the storage unit in the machine, and if the determination result is yes, the user selects the ticket information stored in the storage unit using the information selection unit on the operation panel (step S023), and further reads the transport condition (step S03), and if the determination result is no, the process proceeds to step S024.

At step S024, it is determined whether or not the user has added ticket information, and if the determination result is yes, the user adds and stores the ticket information in the storage unit in association with the transport condition by the information adding unit on the operation panel (steps S025 and S026), selects the ticket information (step S023), and further reads the transport condition (step S03), and if the determination result is no (for example, if the ticket is not familiar and the user does not intend to add and store the ticket information), the user directly inputs the ticket information by the information input unit on the operation panel (step S027), and further reads the transport condition (step S03).

Fig. 20 is a schematic diagram showing an operation panel interface corresponding to whether or not to add ticket information. As shown in fig. 20, when the ticket information is not stored in the storage unit, the operation interface shown in fig. 20 appears. After the user has input information on the operation panel interface, if the user presses the "save" key, the input information is saved in the storage unit, for example, in a blank frame of an image on the operation panel interface shown in fig. 19, the user selects the corresponding receipt information and copies the receipt information, and if the user presses the "direct copy not save" key, the input information is directly copied without being saved.

Fig. 21 is a schematic diagram showing an additional ticket information list corresponding to the operation panel interface of fig. 20. Fig. 22 is a schematic diagram showing a relationship between the type of the receipt and the transport speed. As shown in fig. 20 and 21, for example, a high-speed iron (blue ticket) is a small ticket having a thickness of "thick" and a size of "medium", and since thick paper is relatively thick, the paper is not easily bent, and the transport speed of the rollers needs to be reduced in order to smoothly feed the leading end of the paper to the roller engagement portion. The bus ticket belongs to a small ticket with thin thickness and small size, the thin paper is thinner and weaker in strength, the carrying speed is reduced, the pulling force between the rollers can be reduced, and the situation that the paper is pulled badly is avoided. In other words, the conveyance speed is defined as shown in fig. 22, i.e., V2 > V1 > V3, depending on the thickness of the paper, and it should be noted that the normal paper has moderate paper bending and tensile strength and the conveyance speed is the fastest, so that the rate of the rated invoice, high-speed rail (powder ticket), taxi ticket, shopping invoice, etc., which are close to the thickness of the normal paper, is the fastest.

As described above, the receipt conveyance control method of the present invention includes: acquiring the information of the receipt; reading transportation conditions from a plurality of types of transportation conditions associated with the plurality of types of ticket information stored in the storage unit, respectively, based on the ticket information; and a step of carrying the tickets according to the carrying conditions, so that the tickets can be carried under the carrying conditions according to the relationship between the ticket information and the carrying conditions stored in the storage part, compared with the manual operation, the operation is simpler, and the poor carrying of the tickets in the carrying process or the damage to the tickets can be avoided.

Further, the receipt information is the type of the receipt, so that the optimum transport condition can be selected according to the type of the receipt, for example, a bus invoice, a taxi ticket, a quota invoice, a train ticket, and the like, and the receipt can be prevented from being damaged during transport.

The transport conditions are not limited to the transport speed, and may be the nip pressure, or the transport speed and the nip pressure, and by selecting the optimum transport conditions, it is possible to prevent the tickets from being damaged during the transport process for different types of tickets. The heavy paper has great self weight and strong bending resistance, so that the paper passing resistance in the paper passing track is large, and the clamping pressure needs to be larger than that of the common paper. The thin paper has small self weight and weak bending resistance, so that the paper passing resistance in the paper passing track is small, and the clamping pressure is required to be smaller than that of the common paper.

Further, the method includes a step of adding ticket information, the step including: inputting the type of the receipt by the user; selecting similar ticket information from the plurality of types of ticket information stored in the storage unit; and a step of storing the kind of the slip in association with the carrying condition of the similar slip information, so that the user can add a new kind of the slip, and can add new slip information different from the slip information already stored in the storage section to the storage section in association with the carrying condition, thereby optimizing the storage content of the storage section and facilitating the subsequent operation.

In addition, the step of obtaining the receipt information further comprises: displaying various ticket information on a display part; and a step in which the user selects the ticket information from the plural kinds of ticket information. Therefore, the user can directly select the ticket information, different carrying conditions are adopted for different types of tickets, and the ticket information can be acquired without adding new components. When the ticket information is difficult to automatically recognize due to the fact that the ticket is old or damaged, a user can directly select correct ticket information, the situation that the ticket is conveyed under wrong conveying conditions is avoided, and diversification of operation can be improved.

In addition, the step of obtaining the receipt information further comprises: the step of acquiring the receipt information by detecting the receipt is not required for the user to input or select the receipt information, thereby improving the working efficiency.

In addition, the receipt supply table can be manually opened, and after the user manually opens the receipt supply table, the copying machine is automatically switched to the receipt mode, so that the receipt mode can be entered through various selections, and the working efficiency is improved.

In addition, when the receipt mode is not used for more than the specified time, the copier automatically closes the receipt supply table and enters the original document mode, so that the receipt supply table can serve as a cover plate after being closed, the phenomenon that the receipt is polluted due to the fact that impurities such as dust are attached to the roller is avoided, and meanwhile, the copier is automatically switched to the original document mode after the receipt supply table is closed aiming at the situation that the probability of copying the receipt is lower than that of copying the original document, and the improvement of the working efficiency is facilitated.

< second embodiment >

Fig. 2 is a schematic configuration diagram of an automatic document feeder according to a second embodiment of the present invention. In fig. 2, for ease of understanding, only main components, for example, various rollers, are illustrated, and other components are not illustrated. As shown in fig. 2, the automatic original document feeder 10 according to the second embodiment includes an original document feeding mechanism and a receipt feeding mechanism.

The document conveying mechanism includes a document copying path (hereinafter, the document may be referred to as plain paper, which includes a4 sheets, A3 sheets, and the like), which corresponds to a document platen, a document supply portion including a document supply roller 101, a document conveying path including a plurality of document conveying rollers (in the present embodiment, 8 document conveying rollers (4 pairs of document conveying rollers, and only the document conveying roller pair 103 is illustrated) are illustrated, but the number of document conveying rollers is not limited thereto, and may be less than 8, for example, two, 4, or more than 8, for example, 10, 12), a document reading portion, and a document discharging portion. Wherein the original document table is a member for placing an original document; the document feeder is a member for taking a document on a document platen and feeding the document to a document conveying path formed by a plurality of document conveying rollers; the reading section is a member for reading an original; the document ejection portion is a member that ejects a document that has been read.

The slip transport mechanism includes a slip copy path on the near side of the copier, a movable restricting plate 105 on the near side, a slip supply unit including a slip supply roller 102, and a slip transport path, a slip reading unit, and a slip ejecting unit, each configured by a plurality of slip transport rollers (in the present embodiment, 8 slip transport rollers (4 pairs of slip transport rollers, and only a slip transport roller pair 104 is illustrated) for transporting a slip, but the number of the slip transport rollers is not limited thereto, and may be smaller than 8, for example, two, 4, or larger than 8, for example, 10, 12). Further, the pitch between the adjacent receipt conveying rollers is smaller than the pitch between the adjacent original conveying rollers.

When a slip is to be copied or scanned, first, the position of the movable restriction plate 105 on the near side is manually or automatically adjusted according to the size of the slip to be copied or scanned, thereby adjusting the slip copy passage to a width corresponding to the size of the slip (for example, when the slip copy passage is large relative to the size of the slip, the movable restriction plate 105 on the near side is moved to the near side to reduce the width of the slip copy passage to a width corresponding to the size of the slip, and conversely, when the slip copy passage is small relative to the size of the slip, the movable restriction plate 105 on the near side is moved to the middle to expand the width of the slip copy passage to a width corresponding to the size of the slip). Next, the tickets are placed in the ticket copying path, the tickets placed in the ticket copying path are carried into the ticket carrying path by the ticket supply roller 102, and the tickets are carried to the ticket reading section by the plurality of ticket carrying rollers. Finally, after reading and copying or scanning the image of the receipt, the receipt is transported by a plurality of receipt transport rollers and discharged through a receipt discharge unit.

Note that the slip transport mechanism is not limited to being provided on the near side of the copying machine as described above, and may be provided at various positions between the near side of the copying machine, the middle of the copying machine, and the near side of the copying machine (or the rear side of the copying machine) as the case may be, the slip transport path may be a part of the original transport path without any gap between the slip transport path and the original transport path, and further, a slip supply roller may be newly provided, an existing original supply roller may be used as the slip supply roller, a plurality of slip transport rollers may be newly provided to constitute the slip transport path, and a new slip transport roller may be added between the existing original transport rollers to constitute the slip transport path, and for example, in the existing automatic original transport device shown in fig. 3, a roller-to-roller roll gap L is relatively large, and thus only a plain paper type (A3, a4, etc.) can be handled as long as a new roller-to add a new roller gap 34 between rollers to make a transport roller gap 391 < L (39592), and thus, a slip transport path configuration is possible as shown in fig. 4.

According to the configuration of the second embodiment, since the tickets are conveyed to the reading position along the ticket conveying path by the ticket conveying roller, it is possible to prevent the tickets from being conveyed poorly or damaged during the conveyance, to make it possible to copy or scan images neatly, and to make the operation simpler than the case of manual operation.

Moreover, the receipt copying channel is constructed by using the wall which is originally positioned on the side and the existing movable limiting plate on the near side under the condition of not changing the paper passing path of the common paper of the existing automatic original document carrying device, so that the traditional operation (paper feeding direction, operation side direction and paper outlet) when copying or scanning is carried out by using the automatic original document carrying device is not changed, the strange feeling is not brought to a user, and the adjustment is convenient and flexible.

In addition, the receipt carrying mechanism is arranged at the near side, so the structure is simple and convenient, and a user can conveniently take and place the receipt.

In addition, the movable regulating plate on the near side can regulate both the plain paper and the receipt, that is, when the movable regulating plate on the near side moves toward the middle, the function of regulating the plain paper can be realized, and when the movable regulating plate moves toward the near side, the function of regulating the receipt can be realized.

In the above configuration, a "receipt copy scan mode" (hereinafter, simply referred to as "receipt mode") and a "document copy scan mode" (hereinafter, simply referred to as "document mode") may be provided on the operation panel. When the user presses the "ticket mode" button, only the roller of the ticket conveying mechanism rotates, and when the user presses the "original mode" button, only the roller of the original conveying mechanism rotates. The pair of rollers that do not rotate can separate a space through which the original passes so as not to affect the conveyance of the original. By rotating the rollers of the slip conveyance mechanism and the rollers of the original conveyance mechanism independently of each other, friction between the rollers can be reduced, the service life of the rollers can be prolonged, and noise can be reduced.

< third embodiment >

Fig. 5 is a schematic configuration diagram of an automatic document feeder according to a third embodiment of the present invention. Fig. 6 is a schematic diagram showing an internal path of an automatic document feeder according to a third embodiment of the present invention. In fig. 5 and 6, for convenience of understanding, only main components, for example, various rollers are illustrated, and other components are not illustrated. As shown in fig. 5 and 6, the automatic document feeder 20 according to the third embodiment includes a slip feeding mechanism in addition to a document feeding mechanism, as in the second embodiment.

The slip transport mechanism includes a slip supply unit 200 including a slip supply roller 201 and a slip supply base 202, and a slip transport path for transporting a slip, which includes a plurality of slip transport rollers (4 slip transport rollers (two pairs of slip transport rollers 205 and 206) are illustrated in the present embodiment, but the number of slip transport rollers is not limited thereto, and may be less than 4, for example, two, or more than 4, for example, 6 or 8). Further, the pitch between the adjacent receipt conveying rollers is smaller than the pitch between the adjacent original conveying rollers.

The slip supply section 200 is provided between the original supply section (the original supply roller pair 210) and the reading section 204, and has an openable and closable cover on the side surface of the automatic original transport device 20 close to the slip supply section 200, and when the cover is opened, the cover itself serves as a slip supply table 202, and when the cover is opened, the slip supply roller 201 moves to the slip supply section 200, whereas when the cover is closed, the slip supply table 202 and the slip supply roller 201 return to the original positions. The slip conveyance path is shorter than the original conveyance path, which is located on the user side and between the slip supply section 200 and the original discharge section (original discharge roller pair 207), and in which a portion between the slip supply section 200 and the reading section 204 is formed linearly.

When a slip is to be copied or scanned, first, a cover provided on a side surface of the automatic document feeder 20 close to the slip supply unit 200 is opened. Next, the tickets are placed in the ticket copying path, and the tickets placed in the ticket copying path are conveyed to the reading section 204 by the ticket supply roller 201. Finally, after reading and copying the images of the tickets, the tickets are transported by the ticket

transport roller pair

205, 206 and discharged to the paper exit tray 209 via the document discharge unit (document discharge roller pair 207). Although the width of the receipt supply section 200 in fig. 5 is smaller than the width of the document supply section, the width is not limited to be smaller than the width of the document supply section, and the width may be as wide as the document supply section, and a movable regulating plate for the receipt may be provided.

Note that, a slip supply roller may be newly provided, or an existing one of the original document transport rollers (for example, the original document transport roller 203 in fig. 6) may be used as the slip supply roller, and a slip transport path may be formed by newly providing a plurality of slip transport rollers, or by adding a new slip transport roller between existing original document transport rollers.

According to the configuration of the third embodiment, since the tickets are conveyed to the reading position along the ticket conveying path by the ticket conveying roller, it is possible to prevent the tickets from being conveyed poorly or damaged during the conveyance, to copy or scan images neatly, and to simplify the operation compared with the case of manual operation.

Further, since at least one of the plurality of original transport rollers transports a receipt when transporting a receipt, in other words, the existing original transport roller also transports a receipt by using the receipt transport roller, it is possible to reduce the number of additional receipt transport rollers and to save the cost.

Further, a receipt-dedicated paper feed path is added to the outer end of the conventional automatic original document carrying device, a receipt supply section is provided between the original document supply section and the reading section, and a receipt carrying path is provided between the receipt supply section and the original document discharge section. In other words, since the slip conveying path is shorter than the original conveying path, it is possible to reduce the number of slips conveyed by an excessive number of rollers, thereby reducing the occurrence rate of paper jam.

In addition, in the receipt carrying path, a portion between the receipt supply portion and the reading portion is formed in a straight line shape. The tickets enter the track in a nearly horizontal state and reach the reading part, so that the situation that the tickets are bent and conveyed in the ticket conveying path can be reduced, the tickets are prevented from warping, the occurrence rate of paper jam is reduced, and the images can be copied or scanned in a land-based manner.

In addition, the receipt supply section has a receipt supply roller. The slip can be conveyed into the slip conveying path by the slip supply roller, and the operation is more stable.

The slip supply unit has a slip supply roller, and an openable and closable cover is provided on a side surface of the automatic original document feeder near the slip supply unit, and the slip supply roller is used for conveying an original document when the cover is closed; when the cover is opened, the receipt supply roller supplies a receipt to the receipt conveyance path. Thus, it is not necessary to newly provide a slip supply table and a slip supply roller, and the original document and the slip can be transported by one openable and closable cover.

The receipt conveyance path is located on the user side of the automatic document conveyance device. Therefore, the receipt can be conveniently taken and put, the operation is convenient, and when the original with the size larger than that of the receipt is read, the original can not pass through the receipt supply part, so that the possibility of paper jam of the original can be reduced.

In the above configuration, the operation panel may be provided with "ticket mode" and "document mode" keys. When the user presses the "ticket mode" button, only the roller of the ticket conveying mechanism rotates, and when the user presses the "original mode" button, only the roller of the original conveying mechanism rotates. The pair of rollers that do not rotate can separate a space through which the original passes so as not to affect the conveyance of the original. By rotating the rollers of the slip conveyance mechanism and the rollers of the original conveyance mechanism independently of each other, friction between the rollers can be reduced, the service life of the rollers can be prolonged, and noise can be reduced.

Hereinafter, in order to further understand the case where the slip conveying roller and the document conveying roller are not shared and the case where the slip conveying path is shared, the details will be described with reference to fig. 8 to 15.

Fig. 8 is a schematic view of a slip conveyance path in which the automatic original document carrying device of the second embodiment employs a mode in which a slip conveyance roller and an original document conveyance roller are not shared, fig. 9 is a schematic view of a slip conveyance path in which the automatic original document carrying device of the third embodiment employs a mode in which a slip conveyance roller and an original document conveyance roller are not shared, fig. 10 is a schematic view of a slip conveyance path in which a modification of the automatic original document carrying device of the third embodiment employs a mode in which a slip conveyance roller and an original document conveyance roller are not shared, and fig. 11 is a schematic view of a slip conveyance path in which a mode in which a slip conveyance roller and an original document conveyance roller are not shared is employed in a combination example of the automatic original document carrying device of the second embodiment and the automatic original document carrying device of the third embodiment. Fig. 12 is a schematic view of a slip conveyance path in which the automatic original document carrying device of the second embodiment employs a method in which a slip conveyance roller and an original document conveyance roller are shared, fig. 13 is a schematic view of a slip conveyance path in which the automatic original document carrying device of the third embodiment employs a method in which a slip conveyance roller and an original document conveyance roller are shared, fig. 14 is a schematic view of a slip conveyance path in which a modification of the automatic original document carrying device of the third embodiment employs a method in which a slip conveyance roller and an original document conveyance roller are shared, and fig. 15 is a schematic view of a slip conveyance path in which a method in which a slip conveyance roller and an original document conveyance roller are shared in a combination example of the automatic original document carrying device of the second embodiment and the automatic original document carrying device of the third embodiment.

In fig. 8 to 15, a or a' indicates the start point of the slip transport path, and B indicates the end point of the slip transport path. The shape of the ticket transport path in fig. 8 to 11 is the same as that in fig. 12 to 15 when viewed from the side, but the original document transport path and the ticket transport path overlap each other when viewed from the side in fig. 8 to 11, but are actually shifted from each other when viewed from above, although all or part of the original document transport path doubles as the ticket transport path in fig. 12 to 15.

For example, although the shape of the ticket transport path in fig. 8 is the same as that of the ticket transport path in fig. 12 when viewed from the side, the ticket supply port and the document supply port are at the same position in fig. 12 and share the same pair of paper feed rollers, while the ticket supply port and the document supply port are at the same position when viewed from the side in fig. 8, but may actually be shifted from each other when viewed from above, for example, the configuration in fig. 2.

In the embodiment of fig. 9 and 13, the movement path of the receipt extends substantially horizontally from the receipt supply portion to the paper discharge tray. Therefore, the moving distance of the receipt can be shortened, the delivery rollers of the receipt can be reduced, and the paper jam probability can be reduced.

Note that the form of the slip conveyance path from the slip supply section to the reading section is not limited to the forms of fig. 9 and 13, and as long as the slip conveyance path is provided downstream of the document supply port as in the forms of fig. 10 and 13, the effects of saving rollers and reducing the possibility of paper jam can be achieved as compared with the forms of fig. 8 and 12.

Further, as shown in fig. 11 in which the mode of fig. 8 is combined with the mode of fig. 9, or as shown in fig. 14 in which the mode of fig. 12 is combined with the mode of fig. 13, the tickets can be supplied from the document supply port position or from the ticket supply port, and the operation can be performed more flexibly.
