A print head 500 which is disposed opposite to the outer peripheral surface of the platen roller 300 and prints on the printer paper 100 conveyed by the platen roller 300, a discharge port 110 for discharging the printed printer paper 100, and the discharge port 110. The printer device includes a flexible cover member 320 that prevents foreign matter such as water droplets such as rain and dust from entering the inside of the printer device, and a cutter 310 that cuts the discharged printer paper after printing.
[0005]
The cover member 320 has one end of a sheet-like elastic body fixed to one side of the discharge port 110 in the printer device, and the other end abutted on the other side of the discharge port 110 from the outside of the printer device. Further, on one side of the discharge port 110, the cutter 310 is overlapped and fixed to the cover member 320 from the inside of the printer device so that the cutting edge protrudes from the discharge port 110.
[0006]
In such a printer device, when the printer paper 100 is not discharged, as shown in FIG. 9, the cover member 320 blocks the discharge port 110, and foreign matter or the like enters the printer device from the discharge port 110. To prevent drip and dust.
[0007]
Further, when the printer paper 100 is discharged, the other side of the discharge port 110 and the cover member 320 are brought into contact with the front and back surfaces of the printer paper 100 to prevent the discharge port 110 from being opened, thereby preventing the water and dust. Gaining function.
[0008]
However, in the sheet discharge device provided in the above-described conventional printer device, it is difficult to bring the tip of the cover member 320 into close contact with the discharge port 110, and there is a possibility that water droplets or dust may enter the printer device through the gap. .
[0009]
When the printer paper 100 discharged from the discharge port 110 is cut, the printer paper 100 is turned up together with the cover member 320 and cut against the cutting edge of the cutter 310 as shown in FIG. To do. For this reason, when the printer paper 100 is cut, a gap is formed in the discharge port 110, and there arises a problem that foreign matters such as rainwater and dust enter the apparatus from there.
[0010]
Therefore, in order to solve such a problem, a cutter is provided on one side of the discharge port so as to protrude horizontally from one side of the discharge port to the other side, and is discharged from the discharge port to the other side of the discharge port. A first shielding plate for pressing the printer paper against the blade edge of the cutter, and a second shielding plate on the upper surface of the cutter so as to slightly protrude from the blade edge of the cutter and cover at least the blade edge of the cutter Has been proposed (see Patent Document 1, for example).
[0011]
In such a printer apparatus provided with a dustproof device at the printer paper outlet, when the printer paper 1 is not discharged, the blade edge of the cutter contacts the first shielding plate, and when the printer paper 1 is discharged, the blade edge of the cutter And the first shielding plate sandwich the printer paper to prevent foreign matter from entering the apparatus. Further, the second shielding plate closes a gap generated between the cutter blade edge and the printer paper, or between the cutter blade edge and the first shielding plate, regardless of the shape of the cutter edge, Foreign matter such as rainwater and dust is prevented from entering the printer apparatus from the discharge port.
[0012]
[Patent Document 1]
Japanese Patent No. 2697971
[0013]
[Problems to be solved by the invention]
However, the dust-proof device at the printer paper outlet disclosed in Patent Document 1 prevents the intrusion of foreign matter into the device by bringing the blade edge of the cutter into contact with the first shielding plate or the printer paper. Therefore, considering the unexpected cutting of the printer paper or the breakage of the first shielding plate, it is difficult to bring the blade edge of the cutter into close contact with the first shielding plate or the printer paper. There is a problem of water droplets and dust getting into the water.
[0014]
Further, in addition to the above problems, the conventional printer apparatus shown in FIG. 9 allows the cover member 320 to be pulled by the printer paper when the printer paper is conveyed in the direction of returning to the printer apparatus (during back feed). As a result, there is a problem of being caught in the printer apparatus from the discharge port 110. If the cover member 320 is caught in the discharge port 110, not only can the drip-proof / dust-proof function not be obtained, but it cannot be restored to the normal position only by the elastic force of the cover member 320, and the apparatus is disassembled. Thus, a process such as returning the cover member 320 to the original position is required.
[0015]
