Description

The present invention is output from a recording device (printer) as an information output device in, for example, a word processor, a personal computer, or the like, an image forming apparatus such as a copying machine or a facsimile including recording devices of various recording methods, and the like. that the sheet material as a recording medium relates drilling method by recording equipment provided with a punching device portion for drilling a binding hole for file sheets.

In the past, punching of binding holes for filing sheet materials on which information was recorded or images were copied was manually punched with the sheet materials aligned by hand. 2. Description of the Related Art Copiers and the like have come to be provided with an optional punching device unit that continuously processes sheet materials in combination with the copier. ( See Patent Documents 1 to 4 below ).

However, since the punching device section such as a large copying machine is arranged at a position for punching the sheet material after the recording process etc. is completely completed over the entire surface through a long sheet conveyance path in the copying machine, The arrangement requires a longer sheet conveyance path, and the apparatus in which the copying machine and the punching unit are combined is larger than necessary, so that there is a problem that the installation area must be increased ( see Patent Document 4 below). ).

Also, since the sheet material after undergoing process processing such as recording, transfer, fixing, etc. is punched through a long sheet conveyance path in the copying machine, there is a limit to downsizing the punching device ( see the following patent). References 3 and 4) .

Furthermore, since the punching device used in combination with a conventional copying machine is a method of mechanically engaging a plurality of dies and punches simultaneously, it is difficult to change the number of binding holes with a simple operation. ( See Patent Document 4 below ).

As a technique for solving such a problem, there has been proposed a technique of incorporating a one-hole puncher capable of controlling the timing of making a hole in the feeder unit and making a hole in synchronization with the paper feed speed of the feeder. ( See Patent Document 2 below ). Such a punching device is provided in the paper feeding unit, and therefore, paper with a hole is fed to the recording unit. However, when paper with a hole is conveyed into the recording apparatus, the hole is caught in a part of the conveyance path, and therefore the paper jams frequently and the paper is skewed or jammed in the conveyance path. There is a problem that the reliability of the system is greatly reduced.

  Further, the punching device unit 3 includes a punch 22 for punching holes for binding a plurality of recording sheets on which recording has been completed, a die 23 meshing with the punch 22, and the punch 22. After the die 23 is engaged, a leaf spring 24 that returns the punch 22 to its original position, and a push-down cam that pushes down the punch 22 to the engagement position with the die 23 in conjunction with the rotation of the shaft 26 by the punch drive motor 25. 27 is provided.

  A part 24 a of the leaf spring 24 is provided at a position close to the surface of the recording medium S. Accordingly, the leaf spring 24 also serves as a paper guide member that regulates the lifting of the recording medium S due to the punching operation of the punch 22. By restricting the lifting of the recording medium, the punch 22 can make a precise hole at an accurate position on the surface of the recording medium S.

  The chip storage container 28 stores chips of the recording medium S discharged from the die 23 by the punching operation of the punch 22, and the amount of chips inside can be observed from the direction of arrow A on the front of the apparatus. Some or all of them are made of transparent material. Further, the chip storage container 28 can be pulled out in the direction of arrow A from the front of the apparatus in order to discard the waste inside.

  Further, the scrap amount level sensor 29 composed of a photosensor detects whether the amount of chips in the chip storage container 28 is greater than or less than a predetermined level by looking at the reflection of light by the chips. The waste storage container presence / absence detection means 30 detects whether or not the waste storage container 28 is in the apparatus.

  Next, a control method performed by the control means when the chip storage container is put in and out will be described with reference to FIG.

  FIG. 13 is a flowchart showing the flow of control performed by the control means when the chip storage container is taken in and out.

  In FIG. 13, while the recording apparatus is operating, the control means 21 determines whether or not the chip storage container 28 is put in and out, and the scrap amount level of the chip storage container 28 is the scrap amount level sensor 29 and the presence or absence of the chip storage container. Monitoring is performed through a signal from the detection means 30, and when the control means 21 detects that a container is present in step S29 and the amount of chips is below a predetermined level in step S30, the control means 21 can perform a recording operation in step S31. In step S32, the punching operation is enabled.

  When the amount of chips reaches a predetermined level in step S30, a warning sound is generated or a warning is displayed on the display means 19a in step S33, and the amount of scrap in the chip storage container 28 is equal to or higher than a predetermined level. In step S34, the state of the apparatus is set in a recordable state, and only recording is performed without any problem. In step S35, the drilling operation is stopped and chips are overflowed from the container. To prevent.

  On the other hand, if there is no container in step S29, the user is informed that there is no chip storage container 28 in the apparatus by generating a warning sound or displaying a warning on the display means 19a in step S33, as described above. In step S34, the state of the apparatus is set to a state where the recording operation can be performed, and only recording is always executed without any problem. In step S35, the punching operation is stopped to prevent chips from overflowing.

  As described above, according to the control of the present invention, even if the chip storage container is pulled out during the recording operation or the chip storage container is filled with the chip by the drilling operation during the recording operation, the recording operation is performed. The work is performed without stopping, and no hole is formed, but only the recording can be performed completely, and the damage to the user can be reduced.

[Feeding device section and its operation]
In FIG. 1 and FIG. 2, a print setting item displayed on the display device of the host computer is selected and input with the input means such as a mouse for the paper size, the presence / absence of the file binding hole, and the hole type, and instructed to execute printing. Thus, the control means 21 raises the loading table 8 and starts the feeding operation by a signal from the computer.

  The recording medium S that has risen together with the loading table 8 comes into contact with a feeding roller 9 that rotates clockwise. The abutted uppermost recording medium S is separated one by one by the separation claw 10 and is conveyed until it abuts on the meshing position of the conveying roller pair 13 by the subsequent rotation of the feeding roller 9.

  As one of the conveyance controls, the recording medium S that has come into contact with the stationary engagement position of the conveyance roller pair is such that when the conveyance roller pair 13 starts to rotate in the clockwise direction, the leading edge of the recording medium is caught in the conveyance roller pair 13. In rare cases, the leading end of the medium S moves to the position of the distance L0 at which the recording shown in FIG.

  Therefore, the control means 21 controls the rotation amount of the transport roller pair 13 on the basis of the meshing position of the transport roller pair 13 and moves the recording medium S to the recording or punching position.

  In another conveyance control, in FIG. 2, when the photosensor 12 detects the leading edge of the recording medium S conveyed by the rotation of the feeding roller 9 and the conveying roller pair 13, the control means 21 detects the leading edge. The transport roller pair 13 is rotated by a predetermined amount on the basis of the position, and is moved to the position of the distance L1 at which the recording of the recording medium S is started.

  Therefore, the loading table 8 is lowered and the surface of the recording medium S is separated from the feeding roller 9, so that the recording medium S is transported only by the transport roller pair 13 and is in the state shown in FIG.

  In FIG. 2, the rotation of the carriage motor 17a is transmitted to the carriage 17 as a moving force via the transmission belt 17b. When the recording operation is started, the control unit 21 controls the rotation of the carriage motor 17a and the stepping motor 13a to move the main scanning movement of the carriage 17 and the sub-scanning movement of the recording medium S by the conveying roller pair 13. On the other hand, the recording head 18 records an image on the recording medium S by ejecting ink droplets from a plurality of nozzles arranged in the sub-scanning direction based on image data from the host computer while moving together with the carriage 17. It is.

  When the photosensor 12 detects the trailing edge of the recording medium S during the recording operation, the trailing edge of the recording medium S is continuously conveyed to the printing area of the recording head 18 by the discharge roller pair 14 and recording to the trailing edge is performed. When completed, the recording medium S is discharged out of the discharge port 4 b by the discharge operation of the discharge roller pair 14.

[Detailed description of punching device]
The configuration and operation of the perforating apparatus unit will be described in detail with reference to FIGS.

  1 and 2, the punching device section 3 includes a punch 22 for punching holes, a die 23 that meshes with the punch 22, a plate spring 24 that returns the punch 22 to its original position, and a shaft by a punch drive motor 25. A push-down cam 27 that pushes down the punch 22 is provided in conjunction with the rotation of 26. A part 24a of the leaf spring 24 also serves as a paper guide member.

  3 to 8, the rotation of the stepping motor 13a is decelerated by the motor gear 31 having a small number of teeth and the driven gear 32 having a large number of teeth and is transmitted to the conveying roller pair 13.

  3, 4 and 8, the rotation of the punch drive motor 25 is greatly decelerated by the drive gear 33, the two-stage gear 34, and the driven gear 35 having a large number of teeth in order to increase the torque. The support plate 36 and the part 24a of the leaf spring are bent to transmit the pressure to the push-down cam 27 through a shaft 26 rotatably supported by a support plate 37.

  3 and 7, the control means 21 includes a fan-shaped protrusion 35 a provided on the outer periphery of the driven gear 35 between the light emitting element and the light receiving element of the photosensor 38 provided on the arm portion 36 a of the support plate 36. Since the rotation of the punch drive motor 25 is stopped by a signal generated when the next is interrupted after exiting, the cam lift is highest when the push-down cam 27 integrally coupled with the driven gear 35 is rotated once. Stop at position.

  7 and 8, the pin shaft 39 is fixed to the punch 22 in a state of penetrating through the lateral hole on the side surface of the punch 22. The stepped portions 39a and 39b that are narrowed at both ends of the pin shaft 39 are restricted by the guide grooves 36b and 37b of the support plates 36 and 37 from moving back and forth and left and right, and can move only in the vertical direction. Is engaged.

  Further, the tip of the punch 22 is fitted into a bearing portion 24b provided on a paper guide composed of a part 24a of a leaf spring 24.

  Accordingly, even if the head of the punch 22 receives a force other than the direction along the groove by the rotation of the push-down cam 27, the punch 22 is perpendicular to the recording medium S by the pin shaft 39 and the bearing portion 24b. Move to.

  Further, the pin shaft 39 is in contact with the U-shaped thinned portion 24c at the tip of the leaf spring 24, whereby the pin shaft 39 is always urged by the repulsive force of the leaf spring 24 in the upward direction. Yes.

  A sheet lower guide member 36c configured by bending a part of the support plate 36 is provided with a die 23 having a hole that meshes with the punch 22.

[Punching operation of the punching unit]
When the recording medium S reaches the punching position shown in FIG. 2 by the transport roller pair 13 and the discharge roller pair 14, the punch drive motor 25 shown in FIG. It moves from the position of the photo sensor 38 to a position rotated by 180 ° as shown in FIG.

  The rotation of the driven gear 35 causes the push-down cam 27 to rotate 180 ° as shown in FIG. 6 from the position shown in FIG. 5 so that the push-down surface of the cam comes down.

  The punch 22 pressed by the pressing surface of the pressing cam 27 descends against the force of the leaf spring 24 and meshes with the punch 22 to make a hole in the recording medium S.

  As the driven gear 35 further rotates, the pressing surface of the pressing cam 27 rises, and the punch 22 is lifted by the force of the leaf spring 24 while following the pressing cam 27, and the photo sensor 38 is moved to the fan-shaped protrusion. When the rotation of the punch drive motor 25 stops when 35a is detected, the punch 22 returns to its original position.

  The recording medium S in the state of being bitten by the punch 22 floats as the punch 22 rises, but is immediately regulated by the paper guide of the leaf spring 24. Therefore, the stationary position of the recording medium S is not disturbed by the punching operation.

[Setting and control of file format with different number of holes]
In FIG. 2, the distance L2 between the photosensor 12 and the center of the punch 22, the distance between the photosensor 12 and the transported recording medium S is L3, and the distance between the punch 22 and the recording medium S is La. To do.

  Here, as shown in FIG. 9, FIG. 10, and FIG. 11 showing the file formats with different numbers of holes, the hole-to-hole pitch length P of the recording medium S moving in the arrow B direction is partially normalized. The file format is determined by the type of hole number. On the other hand, the value of La is automatically determined when the type of the number of holes and the size of the recording medium S to be used are set, as shown in the table of FIG.

  The value of L3 is calculated by the following equation (1).

L3 (n) = La + (n−1) × P + L2 (1)
La = value calculated from the table of FIG. 12 L2 = design value = constant n = number of holes, and an integer from 1 to N, which is the number of holes indicated.

  In the middle of the recording operation, the control means 21 counts the value of L3 shown in the above equation (1) N times.

  At each time, the control means 21 stops the rotation of the stepping motor 13a that drives the conveying roller pair 13 so that it does not move even when a small external force is applied to the recording medium S. The push-down cam 27 is rotated by the drive motor 25 to push down the punch 22 to make a hole in the recording medium S.

Here, the value of L3 is shown as a specific example. For example, if the recording medium to be used is designed to be A4 size (294 mm × 210 mm), the number of binding holes is 2, and L2 is 50 mm, when La = 108.5 mm and P = 80 are obtained from FIG. )
1st: L3 (1) = 108.5 + 50 = 158.5 mm (2)
Second: L3 (2) = 108.5 + 80 + 50 = 238.5 mm (3)
It becomes. The above calculation is performed by either the CPU of the host computer or the CPU of the control means 21.

  Inkjet and thermal transfer recording heads are provided with a large number of dot forming elements in the sub-scanning direction in order to increase the recording speed.

Assuming that the dot density at the time of M dots per inch (25.4 mm) is K, a recording width L4 performed by a recording head having W dot forming elements in the sub-scanning direction by one carriage movement is:
K = 25.4 / M (4)
L4 = K × W (5)
It becomes. For example, the dot density K and the recording width T of a recording head having a dot density of 400 dots per inch and 100 dot forming elements in the sub-scanning direction are expressed by the following equations (4) and (5).
K = 25.4 ÷ 400 = 0.0635 mm (6)
L4 = 0.0635 × 100 = 6.35 mm (7)
That is, during the recording operation of the head, the recording medium S is conveyed by the conveying roller pair 13 by 6.35 mm.

  Here, the relationship between the value of the dot density K and the value of the L3 will be described.

L3: Length, K: Dot density, W: Number of dot forming elements N1: Batch recording scan number N2: Number of movements per dot unit F: Remainder when L3 is divided by K: Error from L3 value The following relational expression holds.

L3 = K (W × N1 + N2) + F (8)
Further, since F is a remainder when L3 is divided by K, the following relational expression is established.

F <K <1
F / K (9)
L3 = 158.5 obtained from the above equation (2) into the above equation (8),
K = 0.0635 obtained from the above equation (6)
W = 100 obtained from equation (7) above
And N1 = 24 and N2 = 96, and the above equation (8) is
158.5 = 0.0635 ((100 × 24 + 96) +0.004 (10)
Thus, the value of the term of the dot pitch K (0.0635) in the above equation (10) is the actual movement amount, and the recording medium does not move by the amount of 0.004 of the remaining term. This is an error from the value of L3.

From the relationship of the above equation (9), the value of the remainder term F in the above equation (9) is always smaller than the dot pitch density K. Here, if the error in product specifications is ± E,
| ± E | ≧ | ± K |> F (11)
Here, by setting the error E in the product specification so as to satisfy the relationship of the above expression (11), the value of the remainder term F is considered as an error range in the product specification and can be ignored.

Substituting the values in the above equation (10), K = 0.00635, F = 0.004 into the above equation (11),
| ± E = ± 0.1 | ≧ | ± 0.0635 |> 0.004 (12)
Therefore, it is theoretically possible to reduce the value of E to the value of K, but from a practical viewpoint, by examining the above equation (12), for example, the value of E is about ± 0.1 mm. It can be determined that the value is appropriate.

  In FIG. 3, a stepping motor 13a for driving the pair of conveying rollers 13 is a stepping motor in which one rotation consists of a number of step angles and can be stopped at each step angle. The stepping motor 13a is When rotated by one step angle, the transport roller pair 13 moves the recording medium S by a value of 0.0635 mm corresponding to a one-dot movement pitch. Therefore, the reduction ratio between the motor gear 31 and the driven (roller) gear 35 and the transport roller so that one step angle (a plurality of step angles may be used) of the stepping motor 13a may be the amount of movement. The diameter of 13 is set.

[Flow of recording operation and punching operation with movement of recording medium]
Based on FIGS. 1 and 15, the recording medium S has a specified number of hole distances L3 (n) in the above equations (8) and (10) (the number n here indicates the order of the holes). The transporting operation performed by the stepping motor 13a when moving to the perforation position in FIG.

  FIG. 15 is a flowchart showing a flow of a punching operation accompanied by a recording operation.

  Note that the symbols and numerical values in parentheses shown in the flowchart of FIG. 15 are the symbols and numerical values used in the equations (1) to (10).

  In FIG. 15, after information such as the presence / absence of perforations, the number of holes, the shape of the holes, and the size of the recording medium is designated, and printing is instructed in step S1, the designated information is controlled by the control means. 21.

  If there is no perforation in step S2, the carriage 17 performs main scanning movement under the control of the control means 21 in step S3, and at the same time, the recording head 18 performs a recording operation. When the recording operation is finished, in step S4, the stepping motor 13a is rotated by a W (= 100) step angle to convey the recording medium S by L4 (= 6.35) of the batch recording width.

  If the photosensor 12 does not detect the trailing edge of the recording medium S in step S5, the carriage 17 is moved back to step S3, and the recording head 18 performs recording on the stationary recording medium S. The operation is repeated until the photosensor 12 detects the trailing edge of the recording medium S in step S5. When the trailing edge is detected in step S5, a series of discharge operations are performed in step S6, and the recording medium S is discharged outside the apparatus in step S7.

  If the transmitted information is perforated in step S2, then in step S8, X = 1 is instructed to the next step S9. In step S9, the length L3 (x) obtained from the equation (1) is Calculated.

  In step S10, the carriage 17 performs main scanning movement, and at the same time, the recording head 18 performs a recording operation. When the recording operation is finished, in step S11, the stepping motor 13a rotates by a W (= 100) step angle to convey the recording medium S by L4 (= 6.35).

  If the repetition count is not N1 (= 24) in step S12, the operation returns to step S10 and the carriage 17 moves and the recording head 18 performs recording on the stationary recording medium S. If the repeat count is N1 (= 24) in step S12, the process proceeds to the next step S13.

  In step S13, if the designated hole shape is not an ellipse (for example, in the case of a circle), the process proceeds to step S14. In step S14, the stepping motor 13a rotates by one step angle with the carriage 17 not moving. When the medium S is moved by the dot pitch length K (= 0.0635) and the number of movements in the K length unit reaches N2 (= 96) in step S15, the recording medium S is conveyed to the punching position, and the step In S16, the punch 22 operates to make a first hole in the recording medium S.

  In step S17, the stepping motor 13a rotates by one step angle to move the recording medium S by the dot pitch length K (= 0.0635). In step S18, the number of times of the K length movement is counted. Reaches P−N2 (= 4), the moving length from step S14 becomes L4 that can be collectively recorded.

  If the number of holes drilled in the next step S19 has not reached the designated number, the process proceeds to step S20, where X + 1 is instructed to step S9, and the distance L3 (2) of the next hole position is calculated in step S9. .

  In step S10, the head 18 performs recording on the recording medium S using all elements while the carriage 17 moves in the area of the total length L4 moved in steps S17 and S18.

  Subsequently, the steps of performing the recording operation and the punching operation from step S11 to step S19 until X = specified number is repeated.

  When the number of holes reaches the designated number in step S19, the process goes to step S3, where the carriage 17 performs main scanning movement, and at the same time, the head 18 performs a recording operation.

  When the recording operation is finished, the recording medium S is moved by L4 length corresponding to the collective recording width in step S4, and the operation returns to step S3 to perform recording. In step S5, the photosensor 12 moves the rear end of the recording medium S. Repeat until detected. When the trailing edge is detected in step S5, a discharge operation is performed in step S6, and the recording medium S is discharged outside the apparatus in step S7.

  If the hole shape is elliptical in step S13, the process proceeds to step S21, where the recording medium S moves by the pitch length K (= 0.0635), and in step S22, the number of movements with the length of K is N2. When -J (= 96-J) is reached, the punch 22 operates in step S23, and a hole constituting one part of the ellipse is formed in the recording medium S.

  Subsequently, in step S24, the pitch 22 is moved by the pitch length K (= 0.0635). In step S25, when the number of movements in the K length reaches N2 + J (= 96 + J), the punch 22 is operated in step S26, and recording is performed. A hole constituting the other part of the ellipse is formed in the medium S.

In FIG. 14A, the shape of the ellipse formed by the punching operations in steps S21 and S22 and steps S24 and S25 is such that the radius of the punch 22 is R, and the major axis-minor axis = 2 (J × K), For example, if R = 3, J = 4, and K = 0.0635, the length of the major axis of the obtained ellipse is
Major axis = 2R + 2 (J × K) = 2 × 3 + 2 × 4 × 0.0635 = 6.5
Therefore, this ellipse is an ellipse having a minor axis = 6 and a major axis = 6.5.

  In order to increase the major axis of the ellipse, the value of J may be increased. However, as J increases, the overlapping portion 40 pops out, and the substantial minor axis length of the ellipse decreases.

  In such a case, as shown in FIG. 14 (b), if the number of perforations is increased, for example, if a hole is also formed at the center line position 41, the amount of the overlapping portion 40 popping out is increased even if the major axis is increased. Get smaller.

  The elliptical binding hole as described above is used when the cross section of the binding tool for binding paper is elliptical or rectangular, and different holes can be formed with one punching means as in this apparatus. Therefore, not only the difference in the number of holes but also various types of binding tools having different hole shapes can be used, which is very convenient for the user.

  In step S17, the stepping motor 13a rotates by one step angle, and the recording medium S moves by the dot pitch length K (= 0.0635). In step S18, the number of times of movement of the K length is counted. When P−N2 (= 4) is reached, the movement length from step S14 becomes L4 where batch recording is possible.

  If the number of elliptical holes drilled in the next step S19 has not reached the specified number, the process goes to step S20, where X + 1 is instructed to step S9, and in step S9 the distance L3 (2) of the next hole position is calculated. I do.

  In step S10, the head 18 performs recording on the surface of the recording medium S while the carriage 17 moves along the length L4 moved in steps S17 and S18.

  Subsequently, the movement of the recording medium S, the recording operation, and the punching operation are repeated in steps S11 to S13 and steps S21 to S28. When the number of holes reaches the designated number in step S19 after step S28, the process goes to step S3, where the carriage 17 performs main scanning movement at the length L4 moved in steps S21 to S28, and at the same time, the head 18 is moved. Records.

  When the recording operation in step S3 is completed, in step S4, the stepping motor 13a is rotated by a W (= 100) step angle to convey the recording medium S by L4 (= 6.35) length. If the sensor 12 has not detected the trailing edge of the recording medium S, the operation returns to step S3 where the carriage 17 moves and the head 18 performs recording. In step S5, the photosensor 12 Is repeated until the trailing edge of the recording medium S is detected.

  When the trailing edge is detected in step S5, a discharge operation is performed in step S6, and the recording medium S is discharged outside the apparatus in step S7.
