Description

  The present invention relates to a recording apparatus that records images on a plurality of types of recording media.

In a recording apparatus such as a dot impact printer, an apparatus that performs an alignment operation for correcting a skew of a recording medium is known. This alignment operation is usually adjusted by conveying the recording medium and pressing it against an alignment member. However, when paper with low stiffness is used as the recording medium, if the conveying force when pressed against the alignment member is too strong, the paper may be bent and a paper jam may occur. Therefore, conventionally, the operator determines whether the recording medium is a stiff and stiff sheet or a stiff sheet, and changes the position of the alignment member in accordance with the characteristics of the recording medium. As a result, a recording apparatus has been proposed in which skew correction is not performed on paper with low stiffness (see, for example, Patent Document 1).
JP 7-329377 A

  In the recording apparatus, it is desired that the recording position (printing position) is accurate regardless of whether the paper is stiff. Therefore, it has been demanded that skew correction can be performed even on a sheet with low stiffness. In addition, the recording apparatus disclosed in Patent Document 1 requires an operator to accurately determine a difference in paper characteristics and perform a special operation according to the characteristics of the paper, which places a heavy burden on the operator. It was. Therefore, there has been a demand for a recording apparatus that can perform an operation corresponding to the type of paper and can be easily operated.

  Therefore, the present invention provides a recording apparatus that records images on a plurality of types of recording media, and can perform an alignment operation with a simple operation without damaging the recording media regardless of the type of the recording media. Objective.

  In order to solve the above problems, the present invention provides a recording apparatus for recording an image by projecting a recording wire from a recording head to a plurality of types of recording media, and communicates with an insertion port for inserting the recording medium. A transport path through which the recording medium is transported, an alignment member for aligning the recording medium, and transport means for performing an aligning operation for aligning the recording medium by the aligning member by transporting the recording medium; In the insertion port, a guide display unit for guiding and displaying an insertion position for each type of the recording medium, and a position corresponding to the insertion position for each recording medium in the insertion port on the conveyance path, A plurality of sensors for detecting a recording medium and a type of the recording medium are determined based on detection states of the plurality of sensors, and according to the determination result, Characterized in that it comprises a control means for controlling the operation of said conveying means during the aligning operation.

  According to the present invention, in a recording apparatus that records an image by causing a recording wire to protrude from a recording head with respect to a plurality of types of recording media, the recording medium is conveyed in communication with the insertion port into which the recording medium is inserted. A path, an alignment member for aligning the recording medium, and conveying means for aligning the recording medium by the alignment member by conveying the recording medium. In addition to guiding and displaying the insertion position for each type of recording medium, a plurality of sensors for detecting the recording medium are arranged at positions corresponding to the insertion positions of the recording medium in the insertion port on the conveyance path. The type of the recording medium is determined based on the detection states of the plurality of sensors, and the operation of the conveying unit during the alignment operation is controlled according to the determination result. Because performs accurate operations in accordance with the type of the recording medium, thereby improving the reliability of operation can be reliably prevented a problem of contamination of the recording medium. In addition, the operator who operates the recording apparatus only has to insert the recording medium at the insertion position where guidance is displayed for each type of recording medium, and the work load is remarkably reduced. Furthermore, since the type of the recording medium is determined by detecting the recording medium by a plurality of sensors arranged on the conveyance path corresponding to the insertion position for each recording medium, the type of the recording medium can be quickly determined with an extremely simple configuration. In addition, it has an advantage that it can be accurately determined and can be easily realized at low cost.

  In the present invention, the control unit may set at least one of a conveyance amount or a conveyance speed by the conveyance unit during the alignment according to a determination result of determining the type of the recording medium.

  In this case, the control unit sets at least one of the conveyance amount or the conveyance speed by the conveyance unit at the time of alignment according to the determination result of determining the type of the recording medium. As a result, for example, when the recording medium is rich in strength and elasticity, it is possible to improve the throughput by increasing the conveyance speed during the alignment operation, or to reliably align by increasing the conveyance amount. When the recording medium is poor in strength and elasticity, the recording medium can be prevented from being damaged by reducing the conveying amount during the alignment operation and reducing the conveying speed. In this way, it is possible to improve the reliability of the alignment operation while accurately preventing problems such as contamination of the recording medium in an appropriate manner corresponding to the type of the recording medium.

  Furthermore, in the present invention, the control means may control an impact force when the recording wire protrudes from the recording head according to a determination result of determining the type of the recording medium.

  In this case, since the control means controls the impact force when the recording wire is protruded from the recording head according to the determination result of determining the type of the recording medium, for example, when the recording medium is a copying type recording sheet In addition, the impact force of the recording wire can be strengthened to realize reliable copying. Thus, the certainty of the recording operation can be improved in an appropriate manner corresponding to the type of the recording medium.

  Further, in the present invention, a passbook and a cut sheet can be used as the recording medium, and the guide display unit inserts the passbook toward one side in the width direction of the insertion slot, and the cut sheet Are inserted into the other side of the insertion slot for guidance and display, wherein the plurality of sensors are each a bankbook side sensor disposed corresponding to the insertion position of the bankbook, and the single sheet. A sheet paper side sensor disposed corresponding to the paper insertion position, and the control means detects the recording medium when the recording medium is detected only by the passbook side sensor among the plurality of sensors. When the medium is determined to be the passbook and the recording medium is detected by the cut sheet side sensor among the plurality of sensors, the recording medium may be determined to be the cut sheet. .

  Here, the passbook refers to one having a form in which a plurality of sheets are bound, and the cut sheet is a generic name for one sheet or a plurality of sheets that are overlapped. This sheet includes paper and synthetic resin, and includes specially processed paper such as plain paper and coated paper, and copy paper.

  In this case, a passbook and cut sheet paper can be used as the recording medium, and the guidance display unit inserts the passbook toward one side in the width direction of the insertion slot and brings the cut sheet toward the other side of the insertion slot. The plurality of sensors are respectively disposed corresponding to the passbook side sensor disposed corresponding to the passbook insertion position and the cut sheet insertion position. When the recording medium is detected only by the passbook side sensor among the plurality of sensors, the control means determines that the recording medium is a passbook, and the single sheet of the plurality of sensors When the recording medium is detected by the paper side sensor, it is determined that the recording medium is a cut sheet. Therefore, it is possible to accurately determine whether the recording medium is a passbook or a cut sheet with a very simple configuration. .

  Furthermore, in the present invention, the control means can set the transport amount by the transport means during the alignment operation in two stages, large and small, and can control the transport speed by the transport means during the alignment operation. When the recording medium is determined to be the passbook, the conveyance speed by the conveyance means during the alignment operation is set to a high speed, and can be set in two stages of low speed and high speed. When the amount is set to be large and it is determined that the recording medium is the cut sheet, the transport speed by the transport means during the alignment operation is set to a low speed, and the transport amount is set to be small. Also good.

  In this case, the control means can set the conveyance amount by the conveyance means during the alignment operation in two stages, large and small, and the conveyance speed by the conveyance means during the alignment operation in two stages, low speed and high speed. If it is determined that the recording medium is a passbook, the conveyance speed of the conveyance means during the alignment operation is set to a high speed, the conveyance amount is set to a large value, and the recording medium is a cut sheet Is determined, the transport speed by the transport means during the alignment operation is set to a low speed, and the transport amount is set to a small value. As a result, when a passbook is used as a recording medium, it is possible to improve throughput by transporting at a high speed during the alignment operation, and it is possible to increase the transport amount and to ensure the orientation of the passbook. When cut paper is used as the medium, the cut paper can be transported at a low speed during the alignment operation, and the transport amount can be reduced to align the cut paper without damaging the cut paper.

  In the present invention, when the control unit detects the recording medium in both the passbook side sensor and the cut sheet side sensor, the control unit determines that the recording medium is a wide cut sheet, It is good also as what sets the conveyance speed by the said conveyance means at the time of the said alignment operation to high speed, and sets the conveyance amount large.

  In this case, when the recording medium is detected by both the passbook side sensor and the cut sheet side sensor, the control unit determines that the recording medium is a wide cut sheet, and is conveyed by the conveying unit during the alignment operation. Since the speed is set to a high speed and the carry amount is set to a large value, it is accurate even when using wide cut paper that spans between the passbook insertion position and the cut paper insertion position at the insertion slot. Can respond. The wide cut sheet paper can be reliably oriented by increasing the conveyance amount while improving the throughput by conveying the wide cut sheet toward the alignment member at a high speed.

  Further, in the present invention, the control means can set the impact force when the recording wire is projected by the recording head in two stages, large and small, and determines that the recording medium is the bankbook. In this case, the impact force may be set to a small value, and when it is determined that the recording medium is the cut sheet, the impact force may be set to a large value.

  In this case, the control means can set the impact force when the recording wire is projected by the recording head in two stages, large and small, and if it is determined that the recording medium is a passbook, the impact force is set. If it is set to small and the recording medium is determined to be a cut sheet, the impact force is set to a large value, so for a passbook, recording is not performed without leaving a recording wire dent on the back side of the recording surface. In addition, reliable copying can be realized with copy-type cut paper.

  According to the present invention, a plurality of sensors are arranged on the conveyance path of the recording medium corresponding to the insertion positions for each recording medium that are guided and displayed for each type of recording medium, and according to the detection states of the plurality of sensors. Since the operation of the conveying means during the alignment operation is controlled, an accurate operation is performed according to the type of the recording medium by a simple operation of inserting the recording medium at the guide displayed position, regardless of the type of the recording medium. Thus, the reliability of the operation can be improved while reliably preventing the recording medium from being damaged.

This space is defined as a detection region 714. In addition, there is a space between the upper surface of the light detection unit 712 and the end surface of the light guide tube 713, and this space is a detection region 715. In the state where nothing exists in the detection regions 714 and 715, the light emitted from the light emitting unit 711 reaches the light guide tube 713 through the detection region 714, passes through the light guide tube 713, and is detected from the light guide tube 713. Since the light detection unit 712 is reached via 715, the light detection unit 712 detects light. On the other hand, when there is something that blocks light in at least one of the detection region 714 and the detection region 715, light emitted from the light emitting unit 711 is blocked and does not reach the light detection unit 712. The unit 712 does not detect light. Therefore, the presence / absence of an object in the detection areas 714 and 715 can be detected based on the detection state of the bankbook side sensor 71.

Is. The light guide tube 723 is disposed such that one end surface thereof is located above the light emitting portion 721 and faces the light emitting portion 721, and the other end surface is located above the light detecting portion 722 and faces the light detecting portion 722. The
In the bankbook side sensor 72, a space is generated between the upper surface of the light emitting unit 721 and the end surface of the light guide tube 723. This space is defined as a detection region 724. In addition, there is a space between the upper surface of the light detection unit 722 and the end surface of the light guide tube 723, and this space is a detection region 725. In the state where nothing exists in the detection areas 724 and 725, the light emitted from the light emitting unit 721 reaches the light guide tube 723 through the detection area 724, passes through the light guide pipe 723, and passes through the detection area 725 to detect light. Since the light reaches the unit 722, the light detection unit 722 detects light. On the other hand, when at least one of the detection regions 724 and 725 is such that light is blocked, the light emitted from the light emitting unit 721 is blocked and does not reach the light detection unit 722. Therefore, the light detection unit 722 Does not detect light. Therefore, the presence / absence of an object in the detection areas 724 and 725 can be detected based on the detection state of the bankbook side sensor 72.

  Then, the passbook side sensor 71 and the cut sheet side sensor 72 output signals indicating the detection states in the light detection units 712 and 722 to the control board unit 60 described later.

FIG. 8 is a block diagram illustrating a functional configuration of the control board unit 60 that controls the operation of each unit of the printer body 20. As shown in FIG. 8, the control unit 60 includes a controller 61, and includes functional units such as an interface 62 connected to the controller 61, a recording head drive unit 63, a motor drive unit 64, and a sensor output acquisition unit 66. .
The controller 61 includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., reads a control program stored in the ROM, develops it on the RAM, and executes it by the CPU. To do. The controller 61 controls the operation of the printer 10 by driving and controlling each function unit of the control unit 60.
The interface 62 is connected to an external device (such as a computer) via a communication cable, and transmits / receives various data to / from the external device according to the control of the controller 61. The recording head drive unit 63 is connected to the recording head 31 and controls the recording wire protruding operation by the recording head 31.
The motor drive unit 64 is connected to motors such as the carriage drive motor 65 and the transport motor 36. The motor drive unit 64 controls the operation of the stepping motor such as the transport motor 36 by turning on / off the power supply or outputting a pulse, and supplying power to the other motors. The operation is controlled by switching ON / OFF.
The sensor output acquisition unit 66 acquires signals output from each of the passbook side sensor 71 and the cut sheet side sensor 72 included in the sensor unit 70, determines a detection state in each sensor, and outputs a signal indicating the detection state. Output to the controller 61.

When instructed to start the recording operation, the controller 61 controls the interface 62 to acquire various data such as print data. Then, the controller 61 advances the alignment plate 37 into the conveyance path C and controls the motor driving unit 64 to operate the conveyance motor 36, whereby the recording paper 100 inserted from the medium inlet / outlet 13 is moved to the first conveyance unit 40. Then, an alignment operation for adjusting the orientation of the recording paper 100 by abutting the leading edge of the recording paper 100 against the alignment plate 37 is executed. In this alignment operation, the controller 61 can set the operation speed of the conveyance motor 36 (conveyance speed of the recording paper 100) to at least two stages of high speed and low speed, and further, the operation amount of the conveyance motor 36. It is possible to set the (conveyance amount of the recording paper 100) to at least two levels of large and small.
Subsequently, the controller 61 moves the alignment plate 37 out of the conveyance path C and executes a recording operation. In this recording operation, the controller 61 controls the motor driving unit 64 based on the data acquired from the interface 62 and moves the carriage 30 (FIG. 3) while operating the carriage driving motor 65 to move the carriage 30. The recording paper 100 is conveyed by operating the motor 36, and the recording head driving unit 63 is further controlled to cause the recording wire to protrude from the recording head 31. In this recording operation, the controller 61 can set the impact force when the recording wire protrudes from the recording head 31 in at least two stages of large and small.
Further, the controller 61 executes a paper handling process (FIG. 9) before executing the alignment operation, and based on the detection state of the sensor unit 70 input from the sensor output acquisition unit 66, the transport motor at the time of the alignment operation The setting regarding the operation speed and the operation amount 36 and the impact force of the recording wire from the recording head 31 during the recording operation is changed, and the alignment operation and the recording operation are executed based on the changed setting state.

FIG. 9 is a flowchart showing the paper handling process executed by the controller 61. At the time of executing the paper handling process shown in FIG. 9, the controller 61 functions as the control means of the present invention.
In the paper handling process of FIG. 9, the controller 61 first records the recording paper in either the passbook side sensor 71 or the cut sheet side sensor 72 included in the sensor unit 70 based on the signal input from the sensor output acquisition unit 66. Wait until the presence of 100 is detected (step S1). When the sensor unit 70 detects the presence of the recording paper 100 (step S1; Yes), the controller 61 specifies the sensor that has detected the recording paper 100 (step S2).

If the sensor that detects the recording sheet 100 is only the bankbook side sensor 71 in step S2, the controller 61 determines that the recording sheet 100 is the bankbook 110 (step S3), and performs an alignment operation corresponding to the bankbook 110. And the setting regarding the recording operation is performed (step S4), and the process returns to step S1.
In step S4, the controller 61 reduces the impact force of the recording head 31, increases the transport speed during the alignment operation, and increases the transport amount.
The bankbook 110 is formed by binding a plurality of sheets, and recording is performed on both sides while turning the page. However, if the impact force on the bankbook 110 is too strong, a recording wire dent appears on the back side of the recording surface. There is. In this case, the recording surface is concave and convex on the back side, and the visibility of the image is impaired at the dent portion. In addition, since the copy form is rarely used for the bankbook 110, the impact force may be weak. For this reason, in step S4, the impact force of the recording head 31 is made small corresponding to the bankbook 110.
Further, thick paper is used for the passbook 110 to ensure the strength of the binding portion, and the strength and elasticity of the passbook 110 as a whole are high. For this reason, in the alignment operation in which the bankbook 110 is abutted against the alignment plate 37 (FIG. 7) and the orientation is adjusted, it is preferable to increase the conveyance amount so that the orientation of the bankbook 110 can be adjusted with certainty. Furthermore, since the passbook 110 is excellent in strength, there is no risk of damage even if it is transported at a high speed during the alignment operation, and an improvement in throughput can be expected by transporting at a high speed. For this reason, in step S4, the conveyance speed at the time of the alignment operation is increased corresponding to the bankbook 110, and the conveyance amount is increased.

If the recording paper 100 is detected by both the passbook side sensor 71 and the cut sheet side sensor 72 in step S2, the controller 61 determines that the recording sheet 100 is the wide cut sheet 130 (step S5). ), Setting for the alignment operation and the recording operation is performed corresponding to the wide cut sheet 130 (step S6), and the process returns to step S1.
In step S6, the controller 61 increases the impact force of the recording head 31, increases the transport speed during the alignment operation, and increases the transport amount.
The wide cut sheet 130 may be a copying form, and it is preferable that the recording wire strongly strikes the recording surface of the wide cut sheet 130 in order to perform copy recording with certainty. For this reason, in step S 6, the impact force of the recording head 31 is increased corresponding to the wide cut sheet 130.
Further, since the wide cut sheet 130 is large in size, the deviation when skewed tends to increase. For this reason, in the alignment operation in which the wide cut sheet 130 is abutted against the alignment plate 37 (FIG. 7) and the orientation is adjusted, it is preferable to increase the conveyance amount so that the orientation can be reliably adjusted. In order to prevent a decrease in throughput, it is preferable to carry at high speed. For this reason, in step S6, the conveyance speed during the alignment operation is increased and the conveyance amount is increased corresponding to the wide cut sheet 130.

Furthermore, when the recording sheet 100 is detected only by the cut sheet side sensor 72 in step S2, the controller 61 determines that the recording sheet 100 is the cut sheet 120 (step S7). Correspondingly, settings relating to the alignment operation and the recording operation are performed (step S8), and the process returns to step S1.
In step S8, the controller 61 increases the impact force of the recording head 31, decreases the transport speed during the alignment operation, and decreases the transport amount.
The cut sheet 120 may be a copy form, and it is preferable that the recording wire strongly strikes the recording surface of the cut sheet 120 in order to reliably perform copy recording. For this reason, in step S 8, the impact force of the recording head 31 is increased corresponding to the cut sheet 120.
Further, since the size of the cut sheet 120 is small, the amount of conveyance may be small in the alignment operation in which the cut sheet 120 is abutted against the alignment plate 37 (FIG. 7) and the orientation is adjusted. Further, since the cut sheet 120 is often poor in strength and elasticity, it is preferable that the cut sheet 120 be conveyed at a low speed in the alignment operation so as not to damage the cut sheet 120. In this case, since the conveyance amount at the time of the alignment operation is small, a decrease in throughput due to conveyance at a low speed can be suppressed to the extent that does not cause a problem. Accordingly, in step S8, the conveyance speed during the alignment operation is set to a low speed and the conveyance amount is made small corresponding to the cut sheet 120.

  9, the impact force during the recording operation and the conveyance speed and conveyance amount during the alignment operation are the properties of the passbook 110, the cut sheet 120, and the wide cut sheet 130, respectively. It is set optimally according to. Thereby, the recording paper 100 can be reliably aligned without being damaged.

As described above, according to the present embodiment, in the printer 10 that can use the passbook 110, the cut sheet 120, and the wide cut sheet 130 as the recording sheet 100, the medium entrance / exit 13 for each type of the recording sheet 100. The guide display units 16 and 17 for guiding and displaying the insertion position are arranged, and the passbook side sensor 71 and the single sensor are arranged on the conveyance path C of the recording paper 100 in accordance with the position displayed by the guide display units 16 and 17. An impact when a recording wire is projected from the recording head 31 based on a detection state in the sensor unit 70 by providing a sensor unit 70 including a slip sheet side sensor 72 and executing a paper handling process by the controller 61 of the control board unit 60. The conveyance speed and conveyance amount when the recording sheet 100 is abutted against the alignment plate 37 by the first conveyance unit 40 are set. As a result, in the alignment operation in which the recording paper 100 is abutted against the alignment plate 37 and the orientation is adjusted, and in the recording operation in which an image is recorded by the recording head 31, each of the passbook 110, the cut paper 120, and the wide cut paper 130 is used. It is possible to execute an operation that accurately corresponds to. Accordingly, the passbook 110 having excellent strength and elasticity, the cut paper 120 having poor strength and elasticity, and the wide cut paper 130 having a wide size can be optimally operated according to the characteristics thereof. Thus, the recording paper 100 can be surely aligned and recorded without damaging it.
Further, the operator who operates the printer 10 only has to insert the recording paper 100 into the medium entrance 13 according to the simple guidance display of the guidance display units 16 and 17, and the operation is very simple, and the burden on the operator is reduced. Extremely light. Further, since the type of the recording paper 100 is determined based on the detection state of the passbook side sensor 71 and the cut sheet side sensor 72, it is possible to make a quick and accurate determination with an extremely simple configuration, and at low cost and easily. Is feasible.

  Further, in the paper handling process, when the recording paper 100 is the bankbook 110, the controller 61 sets the transport speed of the first transport unit 40 during the alignment operation to a high speed, sets the transport amount to a large value, and sets the recording wire. Since the impact force is set to be small, throughput can be improved by performing high-speed conveyance, and the direction of the bankbook 110 can be reliably adjusted by increasing the conveyance amount. Can be prevented from remaining on the recording surface. Further, when the recording paper 100 is the cut paper 120, the cut paper 120 is damaged by setting the transport speed of the first transport unit 40 during the alignment operation to a low speed and setting the transport amount to be small. Alignment operation can be performed, and the impact force of the recording wire can be set to be large, so that reliable copying can be realized when the cut sheet 120 is a copy-type sheet. Further, when the recording paper 100 is a wide cut sheet 130, the direction of the first conveyance unit 40 during the alignment operation is set to a high speed and the conveyance amount is set to a large value, so that the direction can be surely adjusted at a high speed. In addition to making it possible to arrange, the impact force of the recording wire can be set to a large value, and reliable copying can be realized when the cut paper 120 is a copying paper.

In the above embodiment, in the paper handling process, the impact force of the recording wire by the recording head 31 and the transport speed and transport amount of the first transport unit 40 during the alignment operation are set. For example, only the impact force of the recording wire by the recording head 31 may be set, or only one of the transport speed and the transport amount of the first transport unit 40 may be set. It is good also as a structure.
Moreover, in the said embodiment, although the light guide tubes 713 and 723 with which the sensor part 70 is provided were made into the shape bent in U shape as shown in FIG. 5, this is using the bankbook side sensor 71 as the 1st conveyance part.
