Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of an increase of the number of parts, enlargement and cost increase brought about due to the fact that detection of an opening and closing state of a printing head that constitutes a printing part, and detection of a state of a movable blade that constitutes a cutter are carried out conventionally by separate sensors. <P>SOLUTION: The printer comprises a printing/cutting unit 3 which sequentially carries out each processing of printing and cutting to a paper let out from a rolled sheet. The printing part 20 is equipped with a platen 21 and the printing head 22 which is constituted to be approachable and separable to the platen and prints to the paper passed through between the platen and the printing head when the printing head approaches the platen. The cutter 30 is equipped with a fixed blade 31 and the movable blade 32 which cuts the paper in cooperation with the fixed blade in a process when reciprocated by a motor. One photo sensor S6 is set which can simultaneously detect both that the movable blade is present at an initial position where an interval enabling passing of the paper is held between the movable blade and the fixed blade, and that the printing head is present at a closure position where printing is possible. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a printing apparatus using roll paper as printing paper, and in particular, after printing on paper fed from roll paper at a printing unit, the paper is cut to a required length with a cutter located on the downstream side, and removed from the machine. The present invention relates to an improvement of a printing apparatus that controls discharge.

For devices that are configured to print the required items on the paper drawn from the roll paper in the printing section, and then issue the ticket after cutting it to the required length, such as a printing device installed in an automatic ticket vending machine A cutting cutter is disposed downstream of the printing unit. When the required length from the front end of the paper that has been printed at the printing section is cut with a cutter and issued outside the machine, the unprinted paper front remaining in the device reaches the cutter, The printing section located upstream from the cutter is located a predetermined distance behind (upstream) from the leading edge of the paper. When a ticket is issued after being cut out by a cutter after a long delivery, an unnecessary blank portion is formed over a wide area at the front part of the printed area of the issued ticket, and it is not easy to see the layout. This raises the problem of increasing the area as necessary.
Further, by keeping two or more roll papers in the printing apparatus, when one roll paper is consumed, the ticketing operation is not interrupted and the other roll paper is switched to the other roll paper. There has also been proposed a printing apparatus that can continuously issue a ticket using a roll paper (Japanese Patent Laid-Open No. 2005-088305).
FIG. 7 is a schematic configuration diagram of a conventional ticket vending machine equipped with two roll papers, and a paper feed unit 100 including roll paper support means 100a that rotatably supports the two roll papers P1 and P2. A printing / cutting unit 101 that receives the paper p1 or p2 fed downward from the roll papers P1 and P2 and sequentially performs printing, cutting, and discharging. The printing / cutting unit 101 includes dedicated paths 102a and 102b for conveying the respective sheets p1 and p2 exclusively, and a common path 104 extending downward from the merge position 103 where the dedicated paths 102a and 102b merge. Yes. On each dedicated path 102a, 102b of the printing / cutting unit 101, a pair of conveying rollers 111 (111a, 111b) are arranged. On the common path 104, a printing unit 112 that prints on the paper p1 and p2, a cutter 113 that cuts the leading end of the paper that has been printed downstream by the printing unit 112 to a predetermined length, and a cutter 113 Discharge roller pairs 114 for discharging (issuing) the cut portions p1-1 and p2-1 to the outside of the machine are sequentially arranged. The printing unit 112, the cutter 113, and the discharge roller pair 114 are merely provided for the two roll papers P1 and P2, and are used in common for both roll papers. When the paper from any one of the roll papers has entered the common path 104 after the printing unit 112, the paper from the other roll paper is sandwiched by the pull-in roller pair 111 and the leading edge thereof. Are in a state of being retracted in the dedicated paths 102a and 102b.
The printing unit 112 includes a platen (roller) 112a and a print head 112b. The print head 112b is configured to be able to approach and separate from the platen 112a.

In this ticket vending machine, since the cutter 113 is located downstream of the printing unit 112, printing is performed within the required length from the leading edge of the paper p1 or p2, and the upstream side of the printed range is cut off at an appropriate position. After the ticket is issued, it is necessary to perform an operation for returning the remaining paper front end to a proper position in the printing unit 112. By performing such reverse feeding of the leading edge of the paper, unnecessary blank portions are not formed over a wide range in the front portion of the printed area of the issued ticket.
As described above, the print head 112b is configured so as to be able to contact with and separate from the platen 112a, so that when the jam occurs, the print head 112b can be moved to a position away from the platen for cleaning the head to perform jam processing and cleaning. Therefore, the bracket that supports the print head is configured to be openable and closable.
In addition, since it is necessary to configure so that paper cannot be transported and printed when the print head is in an open position away from the platen, a part of the bracket is detected by a photo sensor fixedly arranged on the apparatus body side. Thus, it is determined that the bracket, that is, the print head is in the printable position, and if a part of the bracket cannot be detected, it is determined that the bracket is in the unprintable position.
On the other hand, the cutter includes a fixed blade and a movable blade that cuts a sheet passing therethrough by swinging with respect to the fixed blade, and the movable blade is swung by a motor. When the movable blade is in a standby state separated from the fixed blade by a predetermined distance, it is possible to pass the paper through the gap between the two, and the movable blade approaches the fixed paper by moving the movable blade closer to the passing paper. Paper can be cut in between. For this reason, it is necessary for the movable blade to be at the initial position in order for the leading edge of the paper printed by the printing unit to enter between the fixed blade and the movable blade, and it is detected that the movable blade is at the initial position. A dedicated photo sensor is provided.
However, in the conventional printing apparatus, since the open / closed state detection of the print head constituting the printing unit and the state detection of the movable blade constituting the cutter are performed by separate sensors, the number of parts increases, and the large size There was a problem of cost and cost increase.
JP 2005-088305 A

In the present invention, since the sensor provided on the printing unit side or the cutter side is commonly used for the state detection of the printing unit and the state detection of the cutter, the above-described problems can be solved.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a schematic configuration diagram of a printing apparatus according to an embodiment of the present invention, and FIG. 2 is a main configuration diagram thereof.
This printing apparatus 2 is applied to, for example, a ticket vending machine 1, and when a user operates a menu switch on the front face of the ticket vending machine and selects a transaction with a predetermined amount and a predetermined content, an amount and an item corresponding to the selected transaction content are displayed. After printing on the paper surface, the paper is cut to the required dimensions and issued outside the machine.
A ticket vending machine 1 shown in FIG. The printing apparatus 2 feeds the paper p1 from the paper feed unit 5 having a roll paper support means (support shaft) 5a that rotatably supports two roll papers P1 and P2 and the first roll paper P1. A transport mechanism 10 that transports downward, a printing unit 20 that performs printing within a predetermined range (printing range) from the leading ends of the papers p1 and p2 that are fed from the roll paper P1 and P2 by the transport mechanism 10, and printing by the printing unit 20 A cutter 30 disposed downstream of the printing unit 20 to cut a predetermined length position (cutting position) from the front end of the paper later, and a paper piece (ticket) cut by the cutter 30 are discharged out of the machine (ticketing) The discharge roller pair 40 is provided, and a control means 50 for controlling them. The transport mechanism 10, the printing unit 20, and the cutter 30 constitute a printing / cutting unit 3.
In the paper supply unit 5, the center (or outer periphery) of each roll paper P1, P2 is rotatably supported by each roll paper support means 5a. Each of the roll papers P1 and P2 is obtained by winding the papers p1 and p2 for the ticket to be issued in a roll shape. In the factory-shipped state, the front end of the paper is attached to the surface of the roll paper main body with an adhesive tape or the like. When the roll paper is mounted on the printing apparatus because it is fixed, the adhesive tape is manually peeled off from the front end of the paper and the roll paper main body in advance, and then the front end of the paper is manually entered into each entrance of the printing / cutting unit 3. Plug in 3a, 3b.
The roll paper P may be thermal paper or plain paper. In the case of thermal paper, the printing unit 20 uses printing means comprising a thermal head, and in the case of plain paper, printing means for plain paper such as an inkjet head is used.

The printing / cutting unit 3 includes a casing C that accommodates each component, dedicated paths 4a and 4b that communicate with the inlets 3a and 3b and that transport the sheets p1 and p2, respectively, and the dedicated paths 4a, 4a, And a common path 6 extending downward from the joining position A where 4b joins. On each dedicated path 4a, 4b of the printing / cutting unit 3, a pair of transport rollers 11 (11a, 11b) constituting the transport mechanism 10 are arranged. On the common path 6, the printing unit 20 that prints on the paper p <b> 1 and p <b> 2, the cutter 30 that cuts the leading end of the paper that has been printed downstream by the printing unit 20 to a predetermined length, and the cutter 30 cuts it. The discharge roller pairs 40 for discharging (issuing) the cut parts p1-1 and p2-1 to the outside of the machine are sequentially arranged.
The printing unit 20, the cutter 30, and the discharge roller pair 40 arranged in the common path 6 are only provided for the two roll papers P1 and P2, and are common to both roll papers. Therefore, when the paper from either one of the two roll papers enters the common path 6 after the printing unit 20, the paper from the other roll paper is transported to the transport roller pair 11a, or In a state of being nipped by 11b, the front end is retracted into each dedicated path 4a or 4b and waits.
Further, immediately after the entrances 3a and 3b, sensors S1 and S2 for starting the motor and detecting the absence of paper are arranged, respectively. The sensors S1 and S2 are used to detect the entry or discharge of the paper from the respective inlets 3a and 3b, and the detection signals from these sensors S1 and S2 are used to start the motors M1 and M2. Is done. Further, the sensors S1 and S2 use the final portion of the paper fed out from the roll paper with the paper end close to the final printing, cutting, and ticketing, and then the remaining paper portion is transferred to each inlet 3a, It is also used to control the amount of protrusion of the final edge of the paper when it is fed back to 3b and protruded by a predetermined length so that it can be picked and removed by a finger.

Sensors S3 and S4 for detecting standby positions are arranged in dedicated paths 4a and 4b immediately after the pair of transport rollers 11a and 11b, respectively. The standby position detection sensors S3 and S4 detect the leading edge of the paper in order to position (standby) the leading edges of the papers p1 and p2 in the dedicated paths. That is, the sheet enters the unit through the inlets 3a and 3b, passes through the printing unit 20, is subjected to the leading edge aligning process by the cutter 30, and is then fed back to the standby position immediately upstream of the sensors S3 and S4. This is means for detecting the passage of the leading edge of the paper when stopping at. Alternatively, the sensors S3 and S4 are also used for detecting the passage timing of the leading edge of the sheet conveyed by the conveying roller pair 11a and 11b to the downstream side, and detecting whether or not a jam has occurred.
The conveyance roller pairs 11a and 11b are composed of driving rollers 11a ′ and 11b ′ and pinch rollers 11a ″ and 11b ″ that are driven by the driving rollers and that are in contact with and separated from the driving rollers. The drive rollers 11a ′ and 11b ′ are driven by motors M1 and M2, and the pinch rollers 11a ″ and 11b ″ are brought into and out of contact with the drive rollers by solenoids SOL1 and SOL2, respectively. In this example, since the solenoids SOL1 and SOL2 are always OFF, the pinch roller is in contact with the circumferential surface of the drive roller, and the sheet can be conveyed by rotating the drive roller in this state. However, when the solenoid is turned on, each pinch roller is separated from the driving roller, so that the sheet cannot be conveyed.
The printing unit 20 includes, for example, a platen 21 and a head 22 that opens and closes (contacts and separates) from the platen 21, and immediately after a position where the printing unit of the head 22 faces the peripheral surface of the platen 12 (printing position). The print standby position is set. The head 22 advances and retreats between a closed position (printing position) indicated by a solid line and an open position (retracted position) indicated by a broken line, and with respect to a sheet passing between the platen 12 when in the closed position. Print. Further, a sensor S5 for detecting the platen paper position is disposed downstream of the print standby position. The sensor S5 is used for the control means to set the print start position on the paper surface by detecting the paper leading edge position.
A photosensor sensor S6 for detecting the positional relationship with the cutter 30 and head opening / closing is disposed immediately upstream of the printing unit 20. The sensor S6 moves integrally with the head 22 that moves back and forth between the solid line position and the broken line position, and is in the initial position when the head 22 is in the closed position (close position) indicated by the solid line. On the other hand, the sensor S6 is in a retracted state when the head 22 is in an open position (separated position) indicated by a broken line.

The cutter 30 includes a fixed blade 31, a movable blade 2 that cuts a sheet that passes between both blades by moving forward and backward (oscillating) with respect to the fixed blade 31, and a drive source (motor, solenoid) that drives the movable blade. And a transmission member 33 for transmitting the driving force from the driving source to the movable blade. Further, the transmission member 33 includes a detected piece 34 that is detected by the sensor S6 in the initial position only when the movable blade 32 is in the initial position and the print head 22 is in the closed position where printing is possible.
One of the papers p1 and p2 fed out from the respective roll papers P1 and P2 and having the leading end inserted into the printing / cutting unit 3 is used with priority (one that has been inserted first). When the consumption of the paper is finished, conveyance of the paper from the other roll paper is started and used for printing and cutting.
When the leading ends of the papers p1 and p2 fed out from the respective roll papers P1 and P2 are inserted into the inlets 3a and 3b of the printing / cutting unit 3, the sensors S1 and S2 detect the entrance of the leading end of the paper, and based on this detection signal. Then, the control means 50 drives the motors M1 and M2 to rotate the drive rollers 11a ′ and 11b ′, and conveys the paper in the forward direction. In the present embodiment, the paper that has been inserted into the entrance first is used for ticketing, and the paper that is inserted later is automatically switched and used after the previous paper is consumed.
When any one of the papers p1 and p2 is advanced from the dedicated paths 4a and 4b into the common path 6, the forward conveying roller pair 11a or 11b is driven to a position immediately downstream of the printing position. Control is performed to stop the leading edge of the sheet at a certain print standby position. When the leading end of the sheet is at the print standby position, the head 22 is operated to print the required items on the sheet surface, and the sheet is conveyed downstream at a predetermined speed.

At the time when printing of one ticket is completed from the leading edge of the sheet to the predetermined printing range, the cutting portion (corresponding to the length in the conveyance direction of the ticket) from the leading edge of the sheet still reaches the cutter 30. Therefore, the sheet is further advanced while counting the feeding distance of the leading edge of the sheet based on the timing when the sensor S5 detects the leading edge of the sheet. Then, the movable blade 2 is operated to cut the paper at the timing when the position where the front end of the paper is cut reaches the position of the cutter 30. The leading end portion of the sheet separated from the sheet main body by cutting is issued by the discharge roller pair 40 to the outside of the machine. At this time, the paper remaining on the upstream side of the cutter blade 31 is started to be fed back in preparation for the next printing, and is stopped at the print standby position at a predetermined timing after the leading edge of the paper passes the sensor S5. . In this way, every time a ticket is issued, an operation is performed to return the remaining paper tip to the print standby position. Therefore, there is an unnecessary blank in front of the print range of the ticket issued after printing and cutting. It will not be formed.
The characteristic configuration of the present invention is that the sensor S6 is fixed to the movable print head 22 itself and operated together with the print head as described above, and the movable blade 32 constituting the cutter 31 is in the standby position (through-pass). By providing a detected piece 34 on the movable blade side (transmission member 33) for detecting that the sensor S6 at the initial position is in the paper possible position), the head 22 is in the closed position and the movable blade 32. Is that the sensor is simultaneously detected by one sensor S6.

This point will be further described in detail with reference to FIGS. First, FIG. 3 is a diagram showing a configuration example of a driving source of a movable blade, a platen roller, and a discharge roller pair. FIGS. 4A, 4B, and 4C show the print head in the closed position (printable position). FIG. 5 is a diagram illustrating a process of cutting a movable blade by operating a transmission member at a certain time, and FIGS. 5A, 5B, and 5C are views of the cutter as viewed from the sheet conveyance direction, a left side view thereof, FIG. 6A and FIG. 6B are diagrams showing a cutting operation by the fixed blade and the movable blade.
First, as shown in FIG. 3, the platen roller 21 and the discharge roller pair 40 are rotationally driven by a belt 61 wound around an output pulley of a step motor 60.
In addition, the motor 65 fixes one end of the operating piece 66 to the output shaft 65a, and a pin 67 provided at the other end of the operating piece 66 is loosely fitted in a linear elongated hole 33a provided in the transmission member 33. ing. The transmission member 33 includes a base 33A provided with a long hole 33a and a protrusion 33B bent at a predetermined angle from the tip of the base. The projecting portion 33 is provided with a shaft portion 33b engaged with the apparatus main body, and the transmission member 33 is configured to rotate about the shaft portion 33b.
The movable blade 32 is fixedly supported on the protrusion 33B provided at the other end of the transmission member 33, and the motor output shaft 65a is rotated counterclockwise in FIG. 4 from the initial position in FIG. 4A. When the operating piece 66 rotates in the same direction around the output shaft 65a by rotating once in the direction, the state immediately before the cutting in (b) changes to the state immediately after the cutting in (c), and finally the state in (a). Return to. 6A shows a state immediately before cutting, and FIG. 6B shows a state after cutting.
Thus, the movable blade 32 is held at a predetermined angle by the projection 33B of the transmission member 33, and the positional relationship with respect to the fixed blade 31 is changed with the rotation of the transmission member 33, so that FIG. a) In the initial position shown in FIG. 5 (a), a gap S for allowing the paper to pass is formed between the two blades, and in the state immediately before the cutting shown in FIG. In the state immediately after the cutting shown in FIG. 4C, the two blades are crossed.
A detected piece 34 protrudes from a part of the transmission member 33, that is, the tip of the protrusion 33B in this embodiment.

On the other hand, the print head 22 constituting the printing unit 20 is supported by a bracket 25. The bracket 25 is rotatably supported at its upstream end by a shaft 25a, and is provided with a photosensor S6 (photo interrupter) at its downstream end. The bracket 25 rotates between the printable closed position shown in FIG. 4 and the open position rotated clockwise about the shaft 25a. In the closed position of the bracket 25 (print head 22) shown in FIG. 4, the sensor S6 is in the initial position, and the detected piece 34 provided on the movable blade 32 side, that is, on the transmission member 33 side is in a state that can be detected. . When the bracket 25 (print head 22) is not in the closed position, that is, in the open state, the detected piece 34 cannot be detected regardless of the position, so that the bracket 25, that is, the print head 22 can be printed. The control means 50 can determine that there is no error.
On the other hand, when the bracket 25 is in the closed position, that is, when the sensor S6 is in the initial position, the sensor S6 detects the detected piece 34 at the initial position shown in FIG. Only at certain times. Then, when entering the printing operation, the control unit 50 prohibits the printing and cutting operations when the sensor S6 does not detect that the movable blade 32 is in the initial position. That is, printing and cutting are possible only when the print head 22 is in the closed position where printing is possible and the movable blade 32 is in the initial position.
Thus, it becomes possible to detect two items such as whether or not the print head is in a printable position and whether or not the cutter is in a severable state by the single sensor S6. The configuration can be simplified and the cost can be reduced.
In the above embodiment, the sensor is arranged on the printing unit 20 side and the detected piece on the cutter side is provided. On the contrary, the sensor is provided on the cutter side and the detected piece is provided on the printing unit 20 side. May be.
The printing apparatus of the present invention can be applied not only to an automatic ticket vending machine but also to a general apparatus that prints on paper from roll paper and then issues it.
