Description
BACKGROUND OF THE INVENTION

1. Field of the Invention


The present invention relates to a printer apparatus and a method of controlling the printer apparatus.


2. Description of the Related Art


A printer apparatus that issues a sales slip or the like is widely used at a cash register in a shop, an Automated Teller Machine (ATM) or a cash dispenser of a bank or the like. In such a printer apparatus that issues the sales slip or the like, a thermal paper, which is a recording paper, is provided in a rolled state, an image or the like is printed on the recording paper by a thermal head or the like while transferring the recording paper, and the printed recording paper is transferred to a predetermined position where the recording paper is cut with a predetermined length.


In such a printer apparatus, a presenter unit that manages a recording medium after being printed (which will be referred to as a “printed recording medium” or a “printed recording paper”) is provided. With the function of the presenter unit, the recording paper is kept so as not be pulled out while being printed or being cut by a cutter. By providing such a presenter unit, the printed recording paper is introduced into the presenter unit and is ejected from the presenter unit after being cut.


Further, for the presenter unit, a retractor function may be provided by which the ejected printed recording paper, in other words the sales slip or the like, is recovered when the ejected printed recording paper is not taken by a proper user for a predetermined period. With this function, the ejected printed recording paper is not taken by others.


Here, there are various kinds of devices having the presenter function and the retractor function. For example, there is a type in which the printed recording paper is wound around a rolled member or the like and then cut by a cutter to be ejected. However, with such a conventional method, the mechanism of the rolled member may be complicated and the size of the device may be large.


Further, for example, there is a type in which a timing belt or the like is used in a unit having the presenter function or the retractor function as a transfer belt. However, the timing belt or the like is made of a rubber or the like. Thus, the timing belt or the like may extend while using it for a long time causing a reduction in power for transferring the recording paper. In such a case, it is impossible to transfer the recording paper to a desired position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention will be described herein with reference to illustrative embodiments. Those skilled in the art will recognize that many alternative embodiments can be accomplished using the teachings of the present invention and that the invention is not limited to the embodiments illustrated for explanatory purposes.


It is to be noted that, in the explanation of the drawings, the same components are given the same reference numerals, and explanations are not repeated.


First Embodiment
Structure of Printer Apparatus


FIG. 1 is a schematic view showing an example of a printer apparatus 1 of the first embodiment. The structure of the printer apparatus 1 of the embodiment is explained with reference to FIG. 1.


The printer apparatus 1 includes a recording paper damper 11, a control substrate 12, a motor 13, a thermal head 20, a platen roller 21, a cutter unit 30, and a presenter unit 40.


The thermal head 20 prints an image or the like on a recording paper 10, which is in a rolled form. The cutter unit 30 cuts the recording paper 10 on which the image or the like is printed (which will be referred to as a “printed recording paper”) with a predetermined length. The recording paper 10 is a thermal paper or the like. The recording paper 10 is inserted between the thermal head 20 and the platen roller 21 via the recording paper damper 11. Then, while being interposed between the thermal head 20 and the platen roller 21, the image or the like is printed on the recording paper 10 by the thermal head 20.


The cutter unit 30 includes a fixed blade 31 and a movable blade 32. The recording paper 10 on which the characters or the like are printed is cut with the predetermined length when the movable blade 32 is moved with respect to the fixed blade 31.


The control substrate 12 controls printing, ejecting, recovering of the recording paper 10 or the like. The motor 13 is provided for transferring the recording paper 10.


The presenter unit 40 is provided outside of the cutter unit 30 for ejecting the printed recording paper 10 or the like. The presenter unit 40 has a presenter function and a retractor (recovering) function. Specifically, the presenter unit 40 includes a presenter function unit 40a and a retractor function unit 40b.


In this embodiment, the presenter unit 40 is configured to include a drive roller 41 (an example of a first roller), a pinch roller 42 (an example of a second roller), and a connection arm 61. These components function as both the presenter function unit 40a and the retractor function unit 40b.


The drive roller 41 is rotated in a first direction for ejecting the printed recording paper 10 after being cut by the cutter unit 30 (which will be referred to as a “cut printed recording paper”) and a second direction opposite to the first direction for recovering the cut printed recording paper 10. The pinch roller 42 is capable of being rotated in accordance with the rotation of the drive roller 41. The connection arm 61 connects the centers of the drive roller 41 and the pinch roller 42 while pushing the pinch roller 42 toward the drive roller 41 to have the pinch roller 42 move along an outer periphery of the drive roller 41 in accordance with the rotation of the drive roller 41.


The presenter unit 40 is configured such that the movement of the pinch roller 42 along the outer periphery of the drive roller 41 is stopped at a first rotating position when the drive roller 41 is rotated in the first direction at which point the pinch roller 42 interposes and transfers the cut printed recording paper 10 with the drive roller 41 in an ejecting direction E in accordance with the rotation of the drive roller 41. The presenter unit 40 is configured such that the movement of the pinch roller 42 along the outer periphery of the drive roller 41 is stopped at a second rotating position when the drive roller 41 is rotated in the second direction at which point the pinch roller 42 interposes and transfers the cut printed recording paper with the drive roller 41 in a recovering direction R in accordance with the rotation of the drive roller 41.


The presenter unit 40 includes a first stopper member and a second stopper member to stop the movement of the pinch roller 42 at the first rotating position and the second rotating position, respectively.


The presenter function unit 40a includes the drive roller 41, the pinch roller 42, a first transfer belt 51, a fourth roller 44, a fifth roller 45, and a first pinch roller 47. The first transfer belt 51 is hung around the drive roller 41, the fourth roller 44, and the fifth roller 45. The first transfer belt 51 is interposed between the first pinch roller 47 and the fifth roller 45.


In this embodiment, the fourth roller 44 functions as the first stopper member. FIG. 1 shows a state when the movement of the pinch roller 42 along the outer periphery of the drive roller 41 is stopped at the first rotating position. At this time, the first transfer belt 51 is interposed between the pinch roller 42 and the drive roller 42 and between the pinch roller 42 and the fourth roller 44.


The retractor function unit 40b includes the drive roller 41, the pinch roller 42, a second transfer belt 52, a third roller 43, a sixth roller 46, and a second pinch roller 48. The second transfer belt 52 is hung round the drive roller 41, the third roller 43, and the sixth roller 46. These components compose a retractor function unit 40b. The second transfer belt 52 is interposed between the second pinch roller 48 and the sixth roller 46.


In this embodiment, the third roller 43 functions as the second stopper member. As will be explained later, FIG. 5A and FIG. 5B show a state when the movement of the pinch roller 42 along the outer periphery of the drive roller 41 is stopped at the second rotating position. At this time, the second transfer belt 52 is interposed between the pinch roller 42 and the drive roller 41 and between the pinch roller 42 and the third roller 43.


The first transfer belt 51 and the second transfer belt 52 may be timing belts or the like. Alternatively, as long as the first transfer belt 51 and the second transfer belt 52 can transfer the recording paper 10, any other transfer belts or the like may be used.



FIG. 2 is a side view showing an example of the drive roller 41 and the pinch roller 42.


The connection arm 61 is configured to push the pinch roller 42 toward the drive roller 41. For example, the connection arm 61 may be made of an elastic member such as a spring or the like so that a force having the drive roller 41 and the pinch roller 42 be closer to each other is applied. In this embodiment, as shown in FIG. 2, the connection arm 61 includes a torque limiter 62 (an example of an energizing member) to push the pinch roller 42 toward the drive roller 41. The presenter unit 40 further includes a drive gear 63.


The connection arm 61 is connected to the drive roller 41 via the torque limiter 62. By connecting the connection arm 61 via the torque limiter 62, the connection arm 61 synchronously moves with the rotation of the drive roller 41 in the rotation direction, and when a force more than or equal to a predetermined value is applied to the pinch roller 42, only the rotation shaft 41a slips while maintaining the status in which the force is applied to the pinch roller 42.


Further, as shown in FIG. 2, the drive roller 41 may include plural rollers provided in a width direction of the recording paper 10 and configured to be rotated with a rotation shaft 41a. Similarly, the pinch roller 42 may include plural rollers provided in the width direction of the recording paper 10 to correspond to the rollers of the drive roller 41, respectively. Here, the first transfer belt 51 and the second transfer belt 52 are not shown in FIG. 2.


The drive gear 63 is connected to the rotation shaft 41a of the first roller 41. The rotation of the rotation force from the motor is transmitted to the first roller 41 via the drive gear 63 and other gears not shown in the drawings under a control of the control substrate 12 or the like. The transferring speed of the recording paper 10 by the first roller 41 is set to be slower than or equal to that by the platen roller 21. With this structure, the recording paper 10 is not drawn between the first roller 41 and the platen roller 21, so that misprinting is avoided. Thus, the recording paper 10 may be loosened as shown by a dotted line in FIG. 1 between the platen roller 21 and the drive roller 41. In this embodiment, the torque limiter 62 may be configured to be capable of rotating the pinch roller 42 in accordance with the rotation of the drive roller 41 and being applied with a force by the pinch roller 42 which is moved in accordance with the rotation of the drive roller 41.


As shown in FIG. 1, the pinch roller 42 is provided at the outer periphery of the drive roller 41 through the first transfer belt 51 or the second transfer belt 52. With this structure, the pinch roller 42 is capable of rotating around the drive roller 41 within a predetermined range through the first transfer belt 51 or the second transfer belt 52.


The printer apparatus 1 further includes sensors, a first sensor 71 (S1), a second sensor (S2), a third sensor 73 (S3), a fourth sensor 74 (S4), and a fifth sensor 75 (S5), for detecting an existence of the recording paper 10.


Specifically, as shown in FIG. 1, the first sensor 71 (S1) is provided in the vicinity of the drive roller 41. The second sensor 72 (S2) is provided between the drive roller 41 and the third roller 43. The third sensor 73 (S3) is provided between the drive roller 41 and the fourth roller 44. The fourth sensor 74 (S4) is provided in the vicinity of the fifth roller 45. The fifth sensor 75 (S5) is provided in the vicinity of the third roller 43.


(Operation of Printer Apparatus)

An operation of the printer apparatus 1 is explained.


With reference to FIG. 1, in the printer apparatus 1 of the embodiment, after the image or the like is printed on the recording paper 10 by the thermal head 20, the printed recording paper 10 is cut by the cutter unit 30 with a desired width.



FIG. 3A and FIG. 3B are views for explaining an example of the operation of the presenter unit 40. FIG. 3A is a side view and FIG. 3B is a top view. In this embodiment, although an counter-clockwise direction is exemplified as the first direction and a clockwise direction is exemplified as the second direction, the directions may be opposite.


The cut recording paper 10 is first transferred in the ejecting direction E by the presenter function unit 40a of the presenter unit 40. Specifically, as shown in FIG. 3A, the drive roller 41 is rotated in the counter-clockwise direction as shown by an arrow A1.


With this operation, the pinch roller 42 connected to the drive roller 41 via the connection arm 61 moves along the outer periphery of the drive roller 41 in the counter-clockwise direction to the first rotating position at which the movement of the pinch roller 42 is stopped by the fourth roller 44. At the first rotating position, the pinch roller 42 is pushed toward the drive roller 41 with the predetermined force while interposing the first transfer belt 51 therebetween. Thus, the pinch roller 42 is rotated in the clockwise direction in accordance with the rotation of the drive roller 41 as shown by an arrow B2.


The predetermined force applied by the pinch roller 42 to the first transfer belt 51 is determined by the torque limiter 62. By providing the torque limiter 62, the pinch roller 42 is moved along the outer periphery of the drive roller 41 to the first rotating position and then is rotated at the first rotating position while pushing the first transfer belt 51 with the predetermined force. Thus, as the first transfer belt 51 is pushed by the pinch roller 42 and the drive roller 41 with the predetermined force, lowering of a transferring power caused by the looseness of the first transfer belt 51 can be prevented.


In the presenter function unit 40a, as the drive roller 41 is rotated in the counter-clockwise direction as shown by the arrow A1, the first transfer belt 51 is moved in a direction as shown by an arrow C1. Therefore, the fourth roller 44 and the fifth roller 45 are also rotated in the counter-clockwise direction as shown by arrows A4 and A5, respectively, via the first transfer belt 51.


In the retractor function unit 40b, as the drive roller 41 is rotated in the counter-clockwise direction as shown by the arrow A1, the second transfer belt 52 is also moved in a direction as shown by an arrow C2. Therefore, the third roller 43 and the sixth roller 46 are also rotated in the counter-clockwise direction as shown by arrows A3 and A6, respectively, via the second transfer belt 52.


With this operation, the printed recording paper 10 is transferred in the ejecting direction E in the presenter function unit 40a by the first transfer belt 51 and the pinch roller 42. Subsequently, the printed recording paper 10 is further transferred to a position from which a user can pull out the printed recording paper 10 when the rotation of the drive roller 41 is terminated. At this state, a part of the printed recording paper 10 is still inserted between the first transfer belt 51 and the pinch roller 42.


The printing operation of the printer apparatus 1 of the embodiment is terminated when the printed recording paper 10 is pulled by the user at this state. However, if the printed recording paper 10 is not pulled out by the user after a predetermined period, an operation of recovering the printed recording paper 10 is performed after the predetermined period.


Specifically, in this case, as shown in FIG. 4A and FIG. 4B, the drive roller 41 is rotated in the clockwise direction as shown by an arrow B1. With this operation, the pinch roller 42 which is connected to the drive roller 41 via the connection arm 61 moves along the outer periphery of the drive roller 41 in the clockwise direction. FIG. 4A is a side view showing this state, and FIG. 4B is a top view showing this state.


At this time, in the presenter function unit 40a, as the drive roller 41 is rotated in the clockwise direction as shown by the arrow B1, the first transfer belt 51 is moved in a direction shown by an arrow C3. Therefore, the fourth roller 44 and the fifth roller 45 are also rotated in the clockwise direction as shown by arrows B4 and B5, respectively, via the first transfer belt 51.


Further, in the retractor function unit 40b, as the drive roller 41 is rotated in the clockwise direction as shown by the arrow B1, the second transfer belt 52 is moved in a direction as shown by an arrow C4. Therefore, the third roller 43 and the sixth roller 46 are rotated in the clockwise direction as shown by arrows B3 and B6, respectively, via the second transfer belt 52.


In this state, the printed recording paper 10 is moved with the pinch roller 42 while being interposed between the pinch roller 42 and the first transfer belt 51, or between the pinch roller 42 and the second transfer belt 52.


Subsequently, when the drive roller 41 is further rotated in the clockwise direction as shown by the arrow B1, the printed recording paper 10 is transferred in a recovering direction R in the retractor function unit 40b.



FIG. 5A and FIG. 5B are views for explaining an example of the operation of the presenter unit 40. FIG. 5A is a side view showing this state, and FIG. 5B is a top view showing this state. As described above, FIG. 5A and FIG. 5B show a state when the movement of the pinch roller 42 along the outer periphery of the drive roller 41 is stopped at the second rotating position.


With this operation, the pinch roller 42 connected to the drive roller 41 via the connection arm 61 moves along the outer periphery of the drive roller 41 to the second rotating position at which the movement of the pinch roller 42 is stopped by the third roller 43. At the second rotating position, the pinch roller 42 is pushed toward the drive roller 41 with the predetermined force while interposing the second transfer belt 52 therebetween. Thus, the pinch roller is rotated in the counter-clockwise direction in accordance with the rotation of the drive roller 41 as shown by an arrow A2.


The predetermined force applied by the pinch roller 42 to the second transfer belt 52 is determined by the torque limiter 62. By providing the torque limiter 62, the pinch roller 42 is moved along the outer periphery of the drive roller 41 to the second rotating position and then is rotated at the second rotating position while pushing the second transfer belt 52 with the predetermined force. Thus, as the second transfer belt 52 is pushed by the pinch roller 42 and the drive roller 41 with the predetermined force, lowering of a transferring power caused by the looseness of the second transfer belt 52 can be prevented.


In the presenter function unit 40a, as the drive roller 41 is rotated in the clockwise direction as shown by the arrow B1, the first transfer belt 51 is moved in the direction shown by the arrow C3. Therefore, the fourth roller 44 and the fifth roller 45 are also rotated in the clockwise direction as shown by the arrows B4 and B, respectively, via the first transfer belt 51.


In the retractor function unit 40b, as the drive roller 41 is rotated in the clockwise direction as shown by the arrow B1, the second transfer belt 52 is moved in the direction shown by the arrow C4. Therefore, the third roller 43 and the sixth roller 46 are rotated in the clockwise direction as shown by the arrows B3 and B6, respectively, via the second transfer belt 52.


With this operation, the printed recording paper 10 is transferred in the recovering direction R in the retractor function unit 40b by the second transfer belt 52 and the pinch roller 42 to be recovered.


(Method of Controlling Printer Apparatus)

A transferring method of the printed recording paper 10 in the printer apparatus 1 of the embodiment is explained with reference to FIG. 6 to FIG. 10. This transferring method is controlled by the control substrate 12.


First, in step S102, whether the presenter unit 40 is attached to the printer apparatus 1 is determined. When the presenter unit 40 is determined to be attached to the printer apparatus 1 (YES in step S102), the process moves to step S104. On the other hand, when the presenter unit 40 is determined not to be attached, the printed recording paper 10 is ejected and the process is finished as the presenter operation cannot be performed.


In step S104, an operation of receiving the recording paper 10 is performed. This operation is explained in detail with reference to FIG. 7 later.


In step S106, whether the operation of receiving the recording paper 10 is normally completed is determined. When it is determined that the operation of receiving the recording paper 10 is normally completed (YES in step S106), the process moves to step S108. On the other hand, when it is determined that the operation of receiving the recording paper 10 is not normally performed (NO in step S106), the process is finished after an error message or the like is displayed.


In step S108, an operation of pre-ejection of the recording paper 10 is performed. This operation is explained in detail with reference to FIG. 8 later.


In step S110, whether the operation of pre-ejection of the recording paper 10 is normally completed is determined. When it is determined that the operation of pre-ejection of the recording paper 10 is normally completed (YES in step S110), the process moves to step S112. On the other hand, when it is determined that the operation of pre-ejection of the recording paper 10 is not normally completed (NO in step S110), an error or the like is displayed and the process is finished.


In step S112, whether a flag to eject the recording paper 10 is on is determined. Specifically, when the flag to eject the recording paper 10 is previously set to be on at setting of the printer apparatus 1 (YES in step S112), the process moves to step S114. On the other hand, when the flag to eject the recording paper 10 is not on (NO in step S112), the process moves to step S118.


In step S114, an ejection operation of ejection of the recording paper 10 is performed.


This operation is explained in detail with reference to FIG. 9 later.


In step S116, whether the ejection of the recording paper 10 is normally completed is determined. When it is determined that the ejection of the recording paper 10 is normally completed (YES in step S116), the printing operation of the printer apparatus 1 of the embodiment is finished. On the other hand, when it is determined that the ejection of the recording paper 10 is not normally completed (NO in step S116), an error or the like is displayed and the process is finished.


In step S118, whether a flag to recover the recording paper 10 is on is determined. Specifically, when the flag to recover the recording paper 10 is previously set to be on at setting of the printer apparatus 1 (YES in step S118), the process moves to step S120. On the other hand, when the flag to recover the recording paper 10 is not on (NO in step S118), an error or the like is displayed and the process is finished.


In step S120, a recovering operation of recovering the recording paper 10 is performed. This operation is explained in detail with reference to FIG. 10 later.


In step S122, whether the recovering operation of the recording paper 10 is normally completed is determined. When it is determined that the recovering operation of the recording paper 10 is normally completed (YES in step S122), the printing operation of the printer apparatus 1 of the embodiment is finished. On the other hand, when it is determined that the recovering operation of the recording paper 10 is not normally completed (NO in step S122), an error or the like is displayed and the process is finished.


The operation of receiving the recording paper 10 of step S104 is explained in detail with reference to FIG. 7.


First, in step S202, the first sensor 71 (S1) determines whether an existence of the recording paper 10 is detected. When it is determined that the existence of the recording paper 10 is detected by the first sensor 71 (S1) (YES in step S202), the process moves to step S206. On the other hand, when it is determined that the existence of the recording paper 10 is not detected by the first sensor 71 (S1) (NO in step S202), the process moves to step S204.


In step S204, it is determined whether a predetermined period has passed. After the predetermined periods has passed (YES in S204), it is determined that a recording paper jam occurs at an exit of the cutter unit 30. At this time, it is determined that the operation of receiving the recording paper 10 is not normally completed in step S106 shown in FIG. 6. On the other hand, if before the predetermined period has passed (NO in step S204), the process moves back to step S202.


In step S206, the third sensor 73 (S3) determines whether an existence of the recording paper 10 is detected. When it is determined that the existence of the recording paper 10 is detected by the third sensor 73 (S3), the operation of receiving the recording paper 10 is normally completed. At this time, it is determined that the operation of receiving the recording paper 10 is normally completed in step S106 shown in FIG. 6. On the other hand, when it is determined that the existence of the recording paper 10 is not detected by the third sensor 73 (S3), the process moves to step S208.


In step S208, it is determined whether a predetermined period has passed. After the predetermined period has passed in step S208 (YES in step S208), it is determined that a recording paper jam occurs at an entrance of the presenter unit 40. At this time, it is determined that the operation of receiving the recording paper 10 is not normally completed in step S106 shown in FIG. 6. On the other hand, when it is determined that the predetermined period has not passed (NO in step S208), the process moves back to step S206.


As described above, the operation of receiving the recording paper 10 of step S104 shown in FIG. 7 is finished and the process moves to step S106 shown in FIG. 6.


The operation of pre-ejection of the recording paper 10 of step S108 is explained in detail with reference to FIG. 8.


First, in step S302, the fourth sensor 74 (S4) determines whether an existence of the recording paper 10 is detected. When it is determined that the existence of the recording paper 10 is detected by the fourth sensor 74 (S4) (YES in step S302), the process moves to step S306.
