Abstract

PROBLEM TO BE SOLVED: To provide a printer that prevents cut chips of a sheet from overflowing from a storage box for storing the cut chips of the sheet.SOLUTION: The printer comprises: a cutter 30 for cutting a print sheet 2a; a storage box 40 that stores cut chips 30a cut off from the print sheet 2a by cutting off of a margin part of the print sheet 2a with the cutter 30; and a door to be opened and closed when exchanging the print sheet 2a or refilling sheets, where the door is integrated with the storage box 40.

Description

  The present invention relates to a printer, and more particularly to a printer having a storage box for storing cut waste of cut printing paper.

  A conventional printer provided with a cutter for cutting printing paper cuts the blank portion of the printed paper after printing with the cutter and then discharges it. As a result, a printed matter having a blank portion and printed on the entire surface is obtained. In the process of producing a printed matter, cut waste is generated when the margin of the printing paper is cut with a cutter. The cut waste is accumulated in a storage box provided in the printer. The user needs to periodically discard the cut waste accumulated in the storage box. The cut waste is preferably discarded every time the printing paper is replaced.

  However, if sufficient capacity cannot be secured in the storage box due to restrictions on the structure of the printer, or if the number of prints relative to the capacity of the printing paper exceeds the storage capacity of the storage box, the user can remove cut waste from the storage box. Cut waste must be discarded before it overflows. However, in operation, the user may forget to discard the cut waste. When paper cut waste overflows from the storage box, there is a problem in that the overflowed cut waste is caught in the cutter or the printing paper transport path, causing problems such as clogging of the printing paper.

  In order to solve the above-described problem, Patent Document 1 proposes a structure in which a cover of a media slot and a storage box are integrated in a printer including a media slot in a printer body. Here, the media slot is a slot into which a recording medium such as a memory card is inserted. By integrating the cover of the media slot and the storage box, the user can be sure to check the state of cut waste accumulation in the storage box when inserting the media into the media slot and when removing the media from the media slot. .

JP 2005-14242 A

  However, when image data is input to the printer from the outside, for example, when image data is transmitted by connecting the printer and a host PC with a digital interface, the frequency of using the media slot is relatively low. Therefore, the opportunity to open the storage box and dispose of the paper cutting waste is reduced. If the number of machines that dispose of the paper cutting waste is reduced, the paper cutting waste overflows from the storage box, and the above-described problems occur.

  SUMMARY An advantage of some aspects of the invention is that it provides a printer that prevents paper cutting waste from overflowing from a storage box that stores paper cutting waste.

  A printer according to the present invention includes a cutter that cuts printing paper, a storage box that stores cut waste cut from the printing paper by cutting with the cutter, and a door that opens and closes when the printing paper is replaced or replenished. The storage box is integrated with the door.

  According to the printer of the present invention, the user always checks the contents of the storage box when replacing or replenishing the printing paper. That is, it is possible to prompt the user to discard the cut waste every time the printing paper is replaced or replenished. Therefore, it is possible to prevent cutter malfunction and paper jam due to the accumulation of cut waste exceeding the capacity of the storage box. Thereby, a highly reliable printer can be obtained.

Further, dust removing rollers 13a and 13b are provided to remove dust and the like adhering to the printing paper 2a. The printer according to the present embodiment further includes printing paper detection sensors 50a and 50b that detect the printing paper 2a.

  FIG. 3 is a cross-sectional view of the printer according to the first embodiment with the door opened. FIG. 4 is a perspective view of the printer according to the first embodiment with the door opened. As shown in FIGS. 3 and 4, the storage box 40 has a structure that rotates with the bottom serving as a rotation fulcrum 40 a. The storage box 40 is integrated with a door that opens and closes when the roll paper 2 is replaced. That is, the door falls over and opens with the bottom of the storage box 40 as a rotation fulcrum.

<Operation>
First, attachment of the roll paper 2 will be described. The user rotates the storage box 40 in the direction of the arrow in FIG. Then, the door of the printer main body falls over and opens (that is, the state shown in FIGS. 3 and 4), and the roll paper 2 can be replaced. At this time, the user takes out the cut waste accumulated in the storage box 40. When the old roll paper 2 remains, the user takes out the old roll paper 2 and then installs the new roll paper 2. Then, the user pulls out the printing paper 2a from the roll paper 2, and inserts the leading end of the printing paper 2a up to the printing paper detection sensor 50a. When the printing paper detection sensor 50a detects the printing paper 2a, an LED 51 is turned on to indicate that the paper has been sufficiently inserted. By turning on the LED 51, the user can confirm that the printing paper 2a is correctly loaded. After confirming that the LED 51 is turned on, the user closes the door. That is, the storage box 40 is rotated with respect to the rotation fulcrum 40a to return to the original state (that is, the state of FIGS. 1 and 2). At this time, the printing paper 2a comes into contact with the dust removing rollers 13a and 13b.

  Next, the printing operation will be described. When the image data is input to the printer and the printing operation is started, the paper feed roller 9 and the paper feed pinch roller 10 are brought into a pressure-bonded state from a separated state. As the paper feed roller 9 rotates, the printing paper 2a is conveyed to the printing paper detection sensor 50b.

  Next, when the grip roller 7 and the pinch roller 8 are pressure-bonded and the grip roller 7 rotates, the printing paper 2 a is further conveyed toward the discharge port 21 by a predetermined length. Thereafter, the platen roller 6 is pressure-bonded to the thermal head 1, and the ink sheet 5 is heated by the thermal head 1 while the printing paper 2 a is conveyed in the printing direction (direction of winding on the roll paper 2) to print an image.

  The image is transferred in the order of Y (yellow), M (magenta), C (cyan), and OP (overcoat). In accordance with the transfer of each color, the printing paper 2a is also reciprocated and conveyed. With the above operation, an image in which each color is combined is printed in the same area of the printing paper 2a.

  After the printing of the image is completed, the printing paper 2 a is conveyed to the paper discharge roller 14 and the paper discharge pinch roller 15, and is discharged between the paper discharge roller 14 and the paper discharge pinch roller 15 in order to discharge it while applying tension to the paper. After the printing paper 2a is pressure-bonded between the two, the conveyance is continued and the leading edge of the printing paper 2a passes through the cutter 30.

  Then, a blank portion that is not printed is cut by the cutter 30. The cut waste 30 a generated by cutting the blank portion passes through the gap between the discharge guide 20 and the cutter 30 and falls toward the storage box 40. The cut waste 30 a that has dropped toward the storage box 40 enters the storage box 40 from the top of the storage box 40 and accumulates on the bottom of the storage box 40.

  Thereafter, the printing paper 2 a is further conveyed toward the discharge port 21 through the discharge guide 20. Then, the paper is cut again by the cutter 30 at a position that becomes the rear end of the printing paper 2a. The printing paper 2a separated from the roll paper 2 is discharged from the discharge port 21 as a printed matter.

  In the printer of the first embodiment, since the roll paper 2 and the ink sheet 5 are consumables, they must be used up and replaced with new ones.

  From the viewpoint of safety, sensors and the like are attached around the storage box 40, and the printer performs a printing operation unless the storage box 40 is properly closed (that is, the door is not closed). There is nothing.

  In the printer of the first embodiment, since the storage box 40 also serves as a door of the printer body, as shown in FIGS. 3 and 4, the door is used to replace or replenish the printing paper 2a (roll paper 2). When opening the user, the user always confirms the contents of the storage box 40. That is, it is possible to prompt the user to remove the cut waste 30a accumulated in the storage box 40 every time the roll paper 2 is replaced.

  Further, in the first embodiment, it is not necessary to open the printer main body, and the roll paper 2 can be replaced simply by opening the door integrated with the storage box 40.

  In the first embodiment, the case where the printing paper 2a is in the form of a roll has been described. However, a printer 30 that prints on printing paper that has been cut to a predetermined size in advance also includes a cutter 30 for cutting margins and If it is the structure provided with the storage box 40, this invention is applicable.
