The present invention relates to a paper take-up device that can be easily fixed and started to take up, and a printing apparatus having the same.
[0002]
[Prior art]
Conventionally, printing apparatuses (printers) that perform printing on roll paper have been proposed. FIG. 6 is an explanatory diagram showing an example of such a printing apparatus.
[0003]
The printing apparatus 601 takes the following procedure when loading roll paper to be printed.
[0004]
First, the lid 602 is opened. Next, the take-up spindle 603 is removed from the take-up bearing (not shown) by moving upwardly the arm 604 on which the take-up spindle 603 for winding the paper is rotatably fixed. As a result, the sheet retainer 606 of the take-up spindle 603 is opened by the action of a gear mechanism (not shown). FIG. 6 shows the state of the printing apparatus at this time.
[0005]
Next, the roll paper is loaded into the paper stock unit 607, and the end of the roll paper is sandwiched between the paper holder 606 and the main body of the take-up spindle 603.
[0006]
Finally, when the lid 602 is closed, the arm 604 is also moved downward together with this, and the sheet press 606 is closed by the action of a gear mechanism (not shown) to fix the end of the sheet to the take-up spindle 603, and the take-up spindle The roll sheet 603 can be rotated to start winding the roll paper.
[0007]
The platen and the print head are provided in the printing mechanism unit 609, and the roll paper is moved into the printing mechanism unit 609 by the take-up roller 608 to perform printing. In accordance with the movement of the take-up roller 608, the take-up spindle 603 takes up the printed roll paper. When this printing apparatus is used as a store register, a two-layer copy type roll paper is used. The copy-side paper is taken up by the take-up spindle 603 as a store copy, and the customer-side paper is discharged from the printing mechanism 609 as a receipt.
[0008]
When the roll paper loaded in the paper stock unit 607 is finished, the lid 602 is opened, the arm 604 is moved upward, and the wound printed paper is removed from the take-up spindle 603. Thereafter, a new roll paper is loaded into the printing apparatus by the same operation as described above to prepare for printing.
[0009]
On the other hand, there is also a method in which the take-up spindle 603 can be detached from the arm 604 without providing a mechanism such as the paper restraint 606 and the printed paper is stored together with the take-up spindle 603. In this method, the end of the sheet is inserted into a slit of the winding main shaft 603 and fixed.
[0010]
[Problems to be solved by the invention]
However, the paper winding device in the conventional printing apparatus has the following problems.
[0011]
That is, in the former method, the paper is wound so as to be in close contact with the take-up spindle 603, and the paper holder 606 sandwiches the end of the paper between the main body of the take-up spindle 603. The used paper is fixed to the take-up spindle 603. For this reason, it becomes extremely difficult to remove the printed paper from the take-up spindle 603, and if it is forcibly removed, the inside of the paper remains on the take-up spindle 603, and the take-up of the paper is shifted, causing turbulence, There arises a problem that the winding is unwound and entangled or the paper is torn.
[0012]
In the latter method, the printed paper is stored together with the take-up spindle 603, so that there is no turbulence when removing the paper, but a large number of take-up spindles 603 are required, which increases the operation cost. The problem arises. In addition, since the end of the sheet must be inserted into the slit, the preparation labor for enabling printing becomes extremely large, and there is a problem that the time required for preparation becomes long.
[0013]
The present invention has been made to solve these problems. The wound paper can be easily detached from the take-up spindle, and the end of the take-up paper can be easily fixed to the take-up spindle.
