DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-roll in which a plurality of roll-shaped papers having different widths, colors, types, etc. are set, and the papers can be automatically selected and supplied as needed. The present invention relates to a sheet feeding device.

[0002]

2. Description of the Related Art For example, in a hospital, when a medical record is printed, continuous printing is performed on a continuous roll of paper having a predetermined width by the amount of necessary information, and this is cut at an arbitrary position. I have to. When printing sample information such as patient information and test items for a blood test or the like, prepare a sheet in which predetermined sample labels are attached at predetermined intervals on a continuous roll-shaped mount (peeling paper), After printing the sample information on the sample label, the sample label is peeled off and attached to a blood collection tube. Further, these sheets may be color-coded for each operation such as risk management or for each blood.

However, in the conventional printing method, a large number of printers are prepared for each purpose, and the same type of paper is set in each printer and used for a single purpose. Replace and set the same size paper with different colors etc. for one printer,
It is used for multiple purposes. In other words, in the conventional printing method, it is necessary to prepare a printer for each purpose, or to exchange and use sheets each time according to the purpose. Moreover, when replacing the paper according to the purpose, the types of paper that can be replaced are limited in terms of paper width and the like. Therefore, when preparing a large number of printers for each purpose, the initial cost is high, and when replacing and using paper, replacement is troublesome, and there are restrictions on the types of paper that can be replaced. Work required proficiency.

SUMMARY OF THE INVENTION The present invention has been improved and eliminated in view of the above-mentioned problems, and is intended to selectively use a plurality of types of roll-shaped paper sheets mounted thereon. The purpose of the present invention is to provide a multi-roll paper feeding device capable of performing such operations.

[0005] In order to solve the above-mentioned problems, the present invention employs a plurality of roll-shaped sheets each of which is independently and rotatably mounted on one spindle. A drive gear and a feed roll provided corresponding to each sheet, and a clutch gear for transmitting the driving force of the drive gear to the feed roll in conjunction with the drive gear and the feed roll as necessary. This is a multi-roll paper feeding device. According to the present invention, it is possible to feed a roll-shaped sheet by applying a driving force by linking the clutch gear with the drive gear and the feed roll.

According to a second aspect of the present invention, there is provided the multi-roll paper feeding apparatus according to the first aspect, wherein each clutch gear is individually controlled. According to the present invention, by controlling each clutch gear individually, it is possible to select and feed any roll-shaped paper, and to selectively use a plurality of types of roll-shaped paper. Is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below with reference to the embodiments of the invention shown in the drawings. 1 and 2 relate to an embodiment of the present invention. FIG. 1 is a longitudinal sectional side view of the sheet feeding device 1, and FIG. 2 is a longitudinal sectional front view of the sheet feeding device 1. As shown in FIG. 1, in this embodiment, a support shaft 3 for rotatably supporting a plurality of types of roll-shaped papers A to D is attached to the upper center of a housing 2. As the papers A to D, for example, those having a roll diameter of 150 mm at the maximum and a width of 20 to 100 mm can be used. In the case of a label, the length is 3 to 2
Those having a size of 97 mm or more can be used. And the housing 2
A drive gear 4 connected to a drive motor (not shown) corresponding to each of the sheets A to D, a feed roll (rubber roll) 5 and its gear 5a, a clutch gear 6, The rollers 7 are provided as one roll unit.

The drive gear 4 and the gear 5a of the feed roll 5 are separated from each other in a normal state, and are not interlocked. As shown in FIG. 2, the clutch gear 6 meshes with the drive gear 4 and the gear 5 a of the feed roll 5 as necessary, and transmits the driving force of the drive gear 4 to the feed roll 5. . Each of the rolls of paper A to D is guided by a guide roll 8, and is led out from between the feed roll 5 and the paper pressing roller 7 toward the front side. Further, a printer head (not shown) of a thermal transfer type or a thermal type is disposed at a position immediately after the sheets A to D drawn out from between the feed roll 5 and the pressing roller 7. Further, an automatic cutter is provided downstream of the printer head as needed.

From such a state, the roll-shaped papers A to D to be fed are selected, and the clutch gear 6 of the corresponding roll unit is meshed with the drive gear 4 and the gear 5a of the feed roll 5 corresponding thereto. Then, the driving force of the driving gear 4 connected to a driving motor (not shown) is transmitted to the feed roll 5 via the clutch gear 6. Therefore, the feed roll 5
Gives feed to the selected sheet. When one of the papers A to D is selected, the printer head moves to the position of the selected paper in response to this selection, and enters a standby state. When a print command is issued, the printer head reciprocates according to the width of the selected sheet, and prints necessary information such as viewer information or sample information on the sheet. At this time, if the selected paper is a label type paper, the exposed part of the backing paper is detected by the transmission type sensor,
For other types of paper, the timing mark may be detected by a reflective sensor to detect the reference of the paper position. The printed paper is cut and discharged according to the length of the label by an automatic cutter when it is a label type paper, and is cut and discharged to a required length when it is a continuous paper.

As described above, in the present embodiment, an arbitrary one is selected from a plurality of rolled sheets A to D having different sheet widths and types, and necessary items are printed and discharged. Therefore, there is no need to replace the rolled paper as in the related art, and there is no need to prepare a dedicated printer.

By the way, the present invention is not limited to the above-described embodiment. For example, the number of roll-shaped sheets, their type, and sheet width can be appropriately changed.
In this case, it is necessary to make the movement of the printer head correspond to the movement. To do this, the movement of the printer head may be learned in advance or a software measure may be taken. Further, when the printer head is a thermal transfer head, the printer head, the ink ribbon supply roll and take-up roll, and the auto cutter are formed as one unit, and the roll-shaped paper selected by the unit is used as a unit. The patient information may be moved to the position and the patient information or the like may be printed.

[0012]

As described above, in the present invention,
A plurality of roll-shaped papers, each of which is independently rotatably mounted on one support shaft, a drive gear and a feed roll disposed corresponding to each paper, and, if necessary, the drive gear and the feed Since the paper feeder is composed of a clutch gear that transmits the driving force of the drive gear to the feed roll in conjunction with the roll, the clutch gear corresponding to the selected roll-shaped paper meshes with the drive gear and the gear of the feed roll. It is possible to apply a driving force to any roll-shaped sheet and feed the sheet just by causing the sheet to roll.

According to the present invention, by controlling each clutch gear individually, it is possible to select and feed any roll-shaped paper, and to select a plurality of types of roll-shaped paper. It is possible to use it.
