Description

  The present invention relates to a recorder that uses continuous paper.

  Conventionally, for example, in an electrocardiograph, there is one in which a recorder is integrally provided so that a measurement result can be recorded on a recording sheet (see, for example, Patent Document 1). An electrocardiograph recorder (hereinafter simply referred to as a recorder) usually uses continuous paper such as folding paper or roll paper as recording paper.

  When roll paper is used, the entire roll paper is stored and set at a predetermined position in the recorder. On the other hand, when folding paper is used, the entire folding paper is placed outside the recorder, and one end of the folding paper is pulled into the recorder from the paper feed port on the bottom or side of the recorder and set.

  By the way, the setting operation for drawing the folded paper into a predetermined position of the recorder is performed manually by the user prior to printing. In this setting operation, first, the user inserts the folded paper into the recorder from the paper feed port provided on the lower surface of the recorder, and then the user holds one end of the folded paper by hand and places the folded paper at the printing position. Finally, the folding paper is sandwiched between the platen roller and the thermal head at the printing position. In order to prevent jamming during printing, it is necessary to perform this setting operation so that the folded paper is not greatly bent or deviated from the conveyance path in the conveyance path.

  In general, printers and copiers dedicated to printing are equipped with a large number of rollers, and these rollers automatically set the paper up to the printing position, and the paper tension is also suitably maintained. .

  However, unlike a dedicated machine as described above, a recorder that is provided integrally with a medical device such as an electrocardiograph is required to be carried close to the subject and is used near the subject. Therefore, it is required to have a small, lightweight device configuration and excellent quietness.

  The present invention has been made in consideration of the above points, and provides a recorder that can easily and satisfactorily set continuous paper such as folded paper without complicating the apparatus configuration.

One aspect of the recorder of the present invention is:
A printing section for printing on recording paper;
A paper feed port provided below the printing unit;
A first guide portion that guides the recording paper in contact with a first surface of the recording paper in a conveyance path of the recording paper from the paper feed port to the printing section;
A second guide portion provided below the first guide portion and in the vicinity of the paper feed port, and guides the recording paper in contact with a second surface of the recording paper in the transport path;
Have
The first and second guide portions project the recording sheet to the first surface side by contact with the second guide portion and project to the second surface side by contact with the first guide portion. So that it is arranged.

  According to the present invention, tension can be applied to the recording paper without using an attached roller such as a tension roller, and the recording paper can stand on its own without dropping down during the recording paper setting operation. it can. As a result, continuous paper such as folded paper can be set easily and satisfactorily without complicating the apparatus configuration.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a top view showing an external configuration of an electrocardiograph according to an embodiment of the present invention. FIG. 2 is an A-A ′ cross section of the recorder unit of the electrocardiograph of FIG. 1. 2 indicate the conveyance path of the recording paper at the time of printing.

  As shown in FIG. 1, the electrocardiograph 10 includes a touch panel 20, an operation button group 30, and a recorder 40. The electrocardiograph 10 includes an interface unit (not shown) for connecting electrocardiographic electrodes and the like, a control unit (not shown) for performing calculation and operation control, and the like. On the touch panel 20, an electrocardiogram waveform as a measurement result is displayed. In addition, various setting screens and operation menu screens are displayed on the touch panel 20, and the user can perform various settings and operation instructions using the touch panel 20. The operation button group 30 includes a power switch, a start / stop switch, and the like.

  The recorder 40 is integrally provided in an electrocardiograph body including the touch panel 20, the operation button group 30, a control unit (not shown), and the like. The recorder 40 prints an electrocardiogram waveform on a predetermined recording sheet when a user performs a printing operation using a touch panel or a group of operation buttons.

  As shown in FIG. 1, a discharge port 41 through which recording paper after printing is discharged, a case 42, and an open button 43 are provided on the upper surface of the recorder 40. When the open button 43 is operated by the user, the case 42 is in an open state with one end on the discharge port 41 side of the case 42 having an L-shaped cross section jumping upward as shown in FIG. In addition, a platen roller 45 and a paper restricting member 46 are attached to the case 42. When the case 42 is opened, the platen roller 45 and the paper restricting member 46 are moved together with the case 42 in a direction away from the recording paper. To do.

  Further, the recorder 40 is provided with a roll paper attachment portion 47, and the roll paper can be rotatably attached to the roll paper attachment portion 47. Furthermore, paper feed ports 44 and 49 for introducing recording paper into the recorder 40 are formed on the lower surface and side surface of the recorder 40.

  A thermal head 60 is provided at a position facing the platen roller 45. During printing, a recording sheet is sandwiched between the platen roller 45 and the thermal head 60. In this state, the platen roller 45 rotates and the thermal head 60 is rotated. As a result of the operation, an electrocardiographic waveform or the like is printed on the recording paper.

  A first guide part 48 is provided at a position below the printing part composed of the platen roller 45 and the thermal head 60. The first guide portion 48 is a member extending in the width direction of the recording paper (which may be referred to as the axial direction of the platen roller 45), and guides the recording paper conveyed in the direction of the printing portion. The first guide portion 48 is disposed at a position where the contact surface with the recording paper is opposite to the nip portion N1 of the printing portion with the platen roller 45 interposed therebetween. In the case of the example of FIG. 2, since the nip portion N1 is on the right side of the platen roller 45, the first guide portion 48 is disposed at a position where the contact surface with the recording paper is on the left side of the platen roller 45. Has been.

  A second guide portion 50 is provided below the first guide portion 48 and in the vicinity of the paper feed port 44. The second guide portion 50 is a member extending in the width direction of the recording paper (which may be referred to as the axial direction of the platen roller 45), and guides the recording paper conveyed in the direction of the first guide portion 48.

  4 and 5 are perspective views showing the second guide portion 50. FIG. FIG. 4 is a perspective view of the second guide portion 50 as viewed obliquely from above, and FIG. 5 is a perspective view of the second guide portion 50 as viewed from obliquely downward.

  On the lower surface of the second guide portion 50, a paper feed port 51 that is substantially the same size as the paper feed port 44 of the recorder 40 and communicates with the paper feed port 49 is formed. Further, a curved surface 52 with which the recording paper abuts is formed at the rising portion of the second guide portion 50. Further, guide ribs 53 are formed at both end positions of the rising portion of the second guide portion 50.

  When the second guide portion 50 is viewed in FIG. 2, the contact surface with the recording paper (that is, the contact surface of the curved surface 52 with the recording paper) is more than the contact surface of the first guide portion 48 with the recording paper. Is also located on the right side. Thus, as can be seen from the one-dot chain line arrow in FIG. 2, the recording paper introduced into the recorder 40 from the paper feed port 44 is first urged to the right by the second guide portion 50 and then second. After being urged to the left by the one guide portion 48, the nip portion N1 between the platen roller 45 and the thermal head 60 is reached.

  As described above, in the present embodiment, the first guide portion 48 that guides the recording paper by contacting the first surface of the recording paper in the conveyance path from the paper feed port 44 to the printing portion, and the first guide portion 48. And a second guide portion 50 that is provided near the paper feed port 44 and guides the recording paper in contact with the second surface of the recording paper in the transport path. Then, the first and second guide portions 48 so that the recording paper projects to the first surface side by contact with the second guide portion 50 and projects to the second surface side by contact with the first guide portion 48. , 50. Thus, a zigzag (or almost S-shaped) conveyance path is formed by the first and second guide portions 48 and 50. By doing in this way, the recording paper pulled by the platen roller 45 can obtain tension in the entire conveyance path, and the bending of the recording paper in the conveyance path can be reduced.

  Further, the recording paper abuts on the inner side of the guide rib 53 formed in the second guide portion 50, thereby preventing meandering in the width direction. In particular, in the present embodiment, the recording paper abuts on the guide rib 53 in a tensioned state, so that the meandering suppression effect by the guide rib 53 can be enhanced.

  Next, setting of recording paper on the recorder 40 will be described. There are three cases of recording paper sets.

  The first case is a case in which continuous paper such as folded paper is introduced and set from the paper supply port 44 on the lower surface of the recorder 40. In this case, generally, a dedicated cart 100 as shown in FIG. 6 is used. Such a case using the dedicated cart 100 is often performed at the time of an examination at a specialized facility such as a hospital, and the examination is performed by moving the electrocardiograph 10 placed on the dedicated cart 100 to the bedside of the patient. be able to.

  The second case is a case in which continuous paper such as folded paper or A4 size paper is introduced and set from the paper supply port 49 on the side surface of the recorder 40. In this case, the electrocardiograph is directly placed on the table without using the dedicated cart 100 as shown in FIG. 6, and the recording paper is placed beside the electrocardiograph. This case is often performed for health examinations other than dedicated facilities such as hospitals.

  The third case is a case where roll paper is set and used in the roll paper attachment portion 47.

  The configuration of the recorder 40 according to the present embodiment is particularly effective when used in the first case, that is, the case in which continuous paper such as folded paper is introduced and set from the paper feed port 44 on the lower surface of the recorder 40. The first case will be described in detail below.

  The electrocardiograph is mounted on a mounting table 101 of a dedicated cart 100 as shown in FIG. A storage shelf 102 that stores the folded paper 103 is provided below the mounting table 101. A paper passing port 104 that is slightly larger than the width of the recording paper is formed in the mounting table 101, and the folded paper 103 accommodated in the storage shelf 102 passes through the paper feeding port 104 to the paper feeding port 44 of the recorder 40. be introduced.

  When the recording paper is set, the user inserts one end of the folded paper from the paper feed port 44 with the case 42 opened as shown in FIG. 3, and the position where one end of the folded paper exceeds the first guide portion 48. The folded paper is pushed in from the lower side of the paper feed port 44 until it reaches. Next, in this state, the hand is once released, the folded paper is picked up again from the upper side of the apparatus, and one end of the folded paper is set at the printing position. Then, by closing the case 42 in this state, the folded paper is sandwiched between the platen roller 45 and the thermal head 60, and the setting operation is completed.

  Here, in the present embodiment, the first and second guide portions 48 and 50 form a zigzag (or almost S-shaped) conveyance path so that the folded paper is the first. Even if the hand is released from the folded paper in order to hold the folded paper in a state where it has been inserted beyond the guide portion 48, the folded paper does not fall downward and becomes independent at that position. Incidentally, if the folded paper falls below the transport path, a complicated redo work for placing the folded paper on the transport path again becomes necessary. According to the configuration of the present embodiment, even if the user removes his / her hand from the folded paper, it is not necessary to perform such a redo operation. Therefore, even a user who is not familiar with folding paper can easily perform the setting work. Can do.

  Moreover, the 2nd guide part 50 of this Embodiment is formed with the transparent member. Thus, during the setting operation, the user can grasp the positions of the recording paper and the respective members on the other side of the second guide portion 50 via the second guide portion 50, so that the setting operation is facilitated.

  As described above, according to the present embodiment, the recording paper projects to the first surface side of the recording paper by the contact with the second guide portion 50 and the recording paper of the recording paper by the contact with the first guide portion 48. By arranging the first and second guide portions 48 and 50 so as to project to the second surface side, only the platen roller 45 and the guide portions 48 and 50, that is, the attached roller such as a tension roller is not used. However, tension can be applied to the recording paper, and the recording paper can be made to stand by the two guide portions 48 and 50 without dropping downward even during the recording paper setting operation. As a result, it is possible to realize the recorder 40 capable of easily and satisfactorily setting continuous paper such as folded paper without complicating the apparatus configuration.

  Further, since the guide ribs 53 are provided in the second guide portion 50, it is possible to prevent meandering of the recording paper in the transport path, and thus it is possible to prevent printing jams. In particular, when continuous paper is used as the recording paper as in the embodiment, when the paper starts to meander once in the conveyance path, compared to the case where the paper is conveyed one by one, such as A4 size paper, The influence becomes large, and there is a drawback that the amount of meandering is amplified on the downstream side. The recorder 40 of the present embodiment can overcome the disadvantages of using such continuous paper by the guide ribs 53 and prevent printing jams.

  Further, in the recorder 40, the first and second guide portions 48 and 50 are provided at positions avoiding a space for storing the roll paper. Thereby, it is possible to perform printing by introducing the recording paper from the paper supply port 44 on the lower surface while containing the roll paper.

  In the above-described embodiment, the case where the recorder of the present invention is applied to a recorder provided integrally with an electrocardiograph has been described. However, the present invention is not limited to this, and continuous paper is fed from a paper feed port at the bottom of the apparatus. Can be widely applied when used in a recorder that introduces, and the same effects as those of the above-described embodiment can be obtained. In particular, since recording at a medical site often requires recording of an arbitrary length, continuous paper is often used.

  The above-described embodiments are merely examples of implementation in carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereto. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.

  The present invention can be widely applied to a recorder that introduces continuous paper from a paper feed port at the bottom of the apparatus.
