  As such a drip-proof structure in such an electronic device, for example, a structure having a drive mechanism that opens and closes a drip-proof shutter that opens and closes the recording paper discharge port by a drive source such as a motor, or a drive source such as a motor There is a structure that uses a water repellent film and a hydrophilic film to prevent water droplets from entering from the recording paper discharge port.

  In such a drip-proof structure in an electronic apparatus, a structure having a drive source and a drive mechanism has a problem that the structure is complicated and the cost is increased. On the other hand, a structure using a water-repellent film and a hydrophilic film does not require a driving source such as a motor and a driving mechanism for opening and closing the drip-proof shutter, so that the cost can be reduced.

  In this case, the drip-proof structure using the water repellent film and the hydrophilic film is provided with an inclined portion protruding in a chevron shape above the device body located at one edge of the recording paper discharge port, and this inclined portion A water-repellent film is provided, and a hydrophilic film that covers the recording paper discharge port is provided on the apparatus main body located at the other edge of the recording paper discharge port, and the tip of the hydrophilic film is not in contact with the water-repellent film. The structure is made to approach with a slight gap.

  In such a drip-proof structure for electronic devices, when water droplets adhere to the inclined water-repellent film located above the hydrophilic film, the water droplets flow from top to bottom along the water-repellent film. When the ink comes into contact with the front end of the hydrophilic film, it flows along the hydrophilic film, thereby preventing water droplets from entering the apparatus main body from the recording paper discharge port.

  However, in such a drip-proof structure of an electronic device, a water-repellent film is provided on an inclined portion that protrudes from the device body located at one edge of the recording paper discharge port, and the recording paper discharge port Since the hydrophilic film that covers the recording paper discharge port is provided on the apparatus body located on the other edge, the recording paper on which the printing information is printed by the printer unit pushes up the hydrophilic film and In order to pass between the water-repellent films, the end of the hydrophilic film must be placed close to the water-repellent film without contact with the water-repellent film.

  For this reason, in such a drip-proof structure for an electronic device, it is necessary not only to attach a hydrophilic film to the device body and to adjust a slight gap between the hydrophilic film and the water-repellent film at the time of attachment. There is a problem that the adjustment work is complicated and troublesome. In addition, in this drip-proof structure, the water-repellent film and the hydrophilic film are exposed to the outside of the device main body, so that not only the appearance of the device main body is impaired, but also the water-repellent film and the hydrophilic film are likely to collide, Since it is easily damaged, there is a problem in impact resistance and durability.

  The problem to be solved by the present invention is to provide an electronic device having a simple structure and excellent drip-proof property.

  The present invention relates to a device main body, a printer unit provided in the device main body for printing print information on a recording paper, and a recording paper discharge unit for discharging the recording paper printed by the printer unit to the outside of the device main body. The recording paper discharge portion is rotatably provided, and the recording paper discharge portion is opened and closed so as to receive water droplets that have entered the recording paper discharge portion and printed by the printer portion. A drip-proof shutter unit that rotates by the discharge force of the recording paper and sends the recording paper to the recording paper discharge unit, and the recording paper printed by the printer unit is guided to the drip-proof shutter unit, and the guided A recording paper guiding unit for rotating the drip-proof shutter unit by the recording paper discharge force, and avoiding water droplets entering the drip-proof shutter unit from the recording paper discharge unit from the printer unit It was an electronic device, characterized in that it comprises a water droplet discharge unit leading to the outside of the apparatus main body.

  According to the present invention, when water droplets enter the apparatus main body from the recording paper discharge section, the water drops are received by the drip-proof shutter section, and the water droplets received by the drip-proof shutter section are discharged outside the apparatus main body by the water droplet discharge section. In this case, water droplets can be discharged from the printer unit by the water droplet discharge unit.

In this case, the recording paper 15 is a roll paper, and is rotatably stored in a recording paper storage unit 16 provided in the apparatus main body 1 located in the vicinity of the printer unit 14.

  As shown in FIG. 8, when the recording paper 15 is sent from the inside of the recording paper storage unit 16 to the printer unit 14 and printing information is printed, the recording paper discharge port 17 provided in the printer cover 13 is connected to the device main body. 1 is configured to be discharged to the outside. As shown in FIGS. 1 to 4, the recording paper discharge port 17 is an opening formed elongated in a direction orthogonal to the front-rear direction of the printer cover 13.

  That is, as shown in FIGS. 7 and 8, the recording paper 15 is placed at a position of the printer cover 13 located almost directly above the printer unit 14, that is, between the printing unit 14a and the platen unit 14b of the printer unit 14. A corresponding printer cover 13 is provided. In this case, each edge located in the front-rear direction (left-right direction in FIG. 9) of the recording paper discharge port 17 is an inclined surface in which the upper surface side of the printer cover 13 is wide and the lower surface side is narrow, as shown in FIGS. 17a is formed. The printer cover 13 and the recording paper discharge port 17 constitute a recording paper discharge unit.

  By the way, as shown in FIGS. 7 and 8, the printer unit 3 has print information printed by the drip-proof shutter unit 18 that receives water droplets that have entered from the recording paper discharge port 17 of the printer cover 13 and the printer unit 14. A recording paper guiding unit 19 that guides the recording paper 15 to the drip-proof shutter unit 18, and a water droplet discharging unit 20 that guides water droplets that have entered the drip-proof shutter unit 18 from the recording paper discharge port 17 of the printer cover 13 to the outside of the apparatus main body 1. And.

  As shown in FIGS. 7 to 10, the drip-proof shutter unit 18 is rotatably provided below the recording paper discharge port 17 in the apparatus main body 1 and closes the recording paper discharge port 17 so that it can be opened and closed. The recording paper 15 is rotated by the discharge force of the recording paper 15 printed by the printer unit 14 and is sent to the recording paper discharge port 17.

  That is, as shown in FIGS. 7 to 10, the drip-proof shutter unit 18 includes a drip-proof shutter plate 21 for closing the recording paper discharge port 17 so as to be freely opened and closed, and the drip-proof shutter plate 21 in the vicinity of the center of gravity. The drip-proof shutter plate 21 has a so-called seesaw structure that swings in the vertical direction about the support shaft 22.

  As shown in FIGS. 7 to 10, the drip-proof shutter plate 21 is formed by bending a rectangular flat plate slightly larger than the recording paper discharge port 17, and includes a flat plate portion 21a, an inclined portion 21b, and side plate portions 21c on both sides. And have. That is, the drip-proof shutter plate 21 has a configuration in which the inclined portion 21b is inclined upward at one end portion (left end portion in FIG. 9) of the flat plate portion 21a.

  In this case, as shown in FIGS. 7 and 9, the inclined portion 21b is disposed corresponding to the lower side of the recording paper discharge port 17, receives water droplets that have entered from the recording paper discharge port 17, and flows to the flat plate portion 21a. It is configured to temporarily accumulate. Further, as shown in FIGS. 9 and 10, the side plate portions 21c on both sides are respectively provided on both sides of the flat plate portion 21a and the inclined portion 21b (both sides located in the front and back direction of the paper surface in FIG. 9). Yes.

  Accordingly, as shown in FIGS. 7 and 9, the drip-proof shutter plate 21 surrounds the water droplets that have entered from the recording paper discharge port 17 of the printer cover 13 with the flat plate portion 21a, the inclined portion 21b, and the side plate portions 21c on both sides. The water droplets are temporarily accumulated in the broken area, and the accumulated water droplets overflow from the front portion (right side in FIG. 9) of the flat plate portion 21a so as to avoid the printer portion 14.

  As shown in FIGS. 7 to 10, the support shaft 22 that supports the drip-proof shutter plate 21 has a direction orthogonal to the front-rear direction of the flat plate portion 21 a of the drip-proof shutter plate 21 (in FIG. The protruding portions are rotatably attached to a pair of mounting ribs 23 provided on the lower surface of the printer cover 13. In this case, the support shaft 22 has a seesaw structure in which the drip-proof shutter plate 21 swings in the vertical direction by supporting the drip-proof shutter plate 21 so as to be rotatable in the vicinity of the center of gravity.

  That is, as shown in FIGS. 7 to 10, the support shaft 22 is provided at a position slightly away from the center of gravity of the drip-proof shutter plate 21 on the opposite side (right side in FIG. 9) from the inclined portion 21b. Thus, the drip-proof shutter plate 21 has a delicate weight balance, that is, a slight weight of the drip-proof shutter plate 21 so that the inclined portion 21b of the drip-proof shutter plate 21 is always positioned below the recording paper discharge port 17. Due to the difference, the recording paper discharge port 17 is configured to rotate in the closing direction (counterclockwise in FIG. 9).

  On the other hand, the recording paper guide unit 19 guides the recording paper 15 on which the printing information is printed by the printer unit 14 to the lower side of the drip-proof shutter plate 21 of the drip-proof shutter unit 18 as shown in FIGS. In addition, a plurality of guide ribs 24 are provided for rotating the drip-proof shutter plate 21 by the induced discharge force of the recording paper 15.

  As shown in FIGS. 7 to 10, the plurality of guide ribs 24 have a substantially triangular vertical plate shape, and the lower surface of the edge located on one side (left side in FIG. 9) of the recording paper discharge port 17 in the printer cover 13. When the drip-proof shutter plate 21 closes the recording paper discharge port 17, the tip end portion (the right end portion in FIG. 9) of the inclined portion 21b of the drip-proof shutter plate 21 is provided. It is configured to come into contact with each other.

  In this case, as shown in FIGS. 9 to 11, each of the plurality of guide ribs 24 has a front end face 24 a (a left end face in FIG. 11) which is one side of a substantially triangular vertical plate shape as a rear portion at the recording paper discharge port 17. It is configured to hang down at a substantially right angle with respect to the lower surface of the printer cover 13 in a state of being located at the edge of the side (left side in FIG. 11).

  That is, the front end surface 24a of the guide rib 24 has an angle (θ1) with respect to the lower surface of the printer cover 13 at the edge of the recording paper discharge port 17 of the printer cover 13 as shown in FIG. The angle (θ1) is slightly smaller than the angle (θ2) with the straight line (S) in the direction (vertical direction) (θ1 <θ2), and the angle (θ1) with respect to the lower surface of the printer cover 13 is slightly larger than 90 degrees (θ1> 90). Degree) is formed.

  For this reason, as shown in FIG. 11, the plurality of guide ribs 24 are configured such that the front end portion 24 a of each guide rib 24 is discharged from the recording paper of the printer cover 13 because the printer cover 13 is inclined forward and downward on the apparatus main body 1. It is located outside the area (E) corresponding to the vertical direction of the outlet 17 (on the left side in FIG. 11), and is configured such that water droplets dropped from the recording paper discharge port 17 in the vertical direction can be received by the drip-proof shutter plate 21. ing.

  As a result, the drip-proof shutter unit 18 closes the recording paper discharge port 17 when the drip-proof shutter plate 21 rotates about the support shaft 22 due to its delicate weight balance, as shown in FIGS. Further, the tip end portion of the inclined portion 21b of the drip-proof shutter plate 21 comes into contact with and separates from the front end surfaces 24a of the plurality of guide ribs 24, whereby the position of the drip-proof shutter plate 21 in the counterclockwise direction is regulated. It is configured as follows.

  Further, as shown in FIGS. 7 to 10, the plurality of guide ribs 24 are such that the recording paper 15 printed by the printer unit 14 comes into contact with the front end surface 24 a of each guide rib 24, and the recording paper 15 that has come into contact with each front end 24 a. It is configured to be guided upward by the surface 24a. Thus, the plurality of guide ribs 24 guide the recording paper 15 to the tip of the inclined portion 21 b of the drip-proof shutter plate 21, and push up and rotate the drip-proof shutter plate 21 by the discharge force of the guided recording paper 15. Thus, the recording paper 15 is fed between the front end surface 24 a of the guide rib 24 and the tip end portion of the inclined portion 21 b of the drip-proof shutter plate 21.

  Further, as shown in FIGS. 7 to 10, the recording paper guiding portion 19 is provided on the lower surface of the printer cover 13, and a plurality of guide ribs 24 that come into contact with the inclined portion 21 b of the drip-proof shutter plate 21 so as to be able to contact and separate. The inclined portion 21b of the drip-proof shutter plate 21 is in contact with the plurality of guide ribs 24 so as to be able to contact and separate.

  As a result, the recording paper guiding section 19 prevents the recording paper 15 printed by the printer section 14 from being guided to the drip-proof shutter plate 21 of the drip-proof shutter section 18 as shown in FIGS. The recording paper 15 is also guided by the inclined portion 21b of the droplet shutter plate 21 toward the tip end portion of the inclined portion 21b, so that the recording paper 15 is formed between the front end surface 24a of the guide rib 24 and the inclined portion 21b of the drip-proof shutter plate 21. It is comprised so that it may send in between a front-end | tip part.

  Further, as shown in FIGS. 7 and 8, the water droplet discharge unit 20 includes a cover case 25 that covers the printer unit 14 and an inner wall of the device main body 1 except between the printing unit 14 a and the platen unit 14 b of the printer unit 14. Is a discharge path provided between the two. The water droplet discharge unit 20 avoids water droplets from the printer unit 14 when water droplets that have entered the drip-proof shutter plate 21 of the drip-proof shutter unit 18 from the recording paper discharge port 17 flow down from the drip-proof shutter plate 21. Then, it is configured to be guided to the outside from the lower part of the device body 1 and discharged.

  By the way, the case where the printer cover 13 which is a recording paper discharge part of such an electronic register is manufactured will be described. The printer cover 13 is formed by a molding die 26 as shown in FIG. The molding die 26 includes an upper die 27 and a lower die 28. The upper mold 27 and the lower mold 28 have a parting line PL set along the lower surface of the printer cover 13.

  In this case, as shown in FIG. 11, the plurality of guide ribs 24 formed on the printer cover 13 are formed such that the angle (θ1) of the front end surface 24a with respect to the lower surface of the printer cover 13 is slightly larger than 90 degrees. For this reason, as shown in FIG. 12, the upper mold 27 is provided with a first forming protrusion 27a that forms the recording paper discharge port 17 so as to protrude downward. The second formation projection 27 b for forming the front end surface 24 a of the guide rib 24 is provided to protrude below the recording paper discharge port 17.

  Thereby, as shown in FIG. 12, when the upper mold 27 and the lower mold 28 overlap each other in the molding mold 26, a cavity 29 corresponding to the printer cover 13 is formed inside both of them. And a cavity 30 corresponding to the plurality of guide ribs 24 is formed. Then, after the resin is injected into these cavities 29 and 30, the upper mold 27 and the lower mold 28 are released.

  At this time, as shown in FIG. 12, the second forming projection 27 b of the upper mold 27 for forming the front end surface 24 a of the guide rib 24 passes through the portion corresponding to the recording paper discharge port 17, thereby The mold 27 and the lower mold 28 are easily released. Thereby, the printer cover 13 having the plurality of guide ribs 24 can be taken out from the molding die 26.

Next, the operation of such an electronic register will be described.
In this electronic register, when the operator operates the touch input unit 6 of the input display unit 2 and inputs information such as the price and product name of a product purchased by the customer, the input information is displayed on the touch input unit 6 and the rotation. It is displayed on the display unit 11 of the display 4. As a result, the operator can confirm the input information by looking at the information displayed on the touch input unit 6 of the input display unit 2, and the customer can see the information displayed on the display unit 11 of the rotary display 4. The input information can be confirmed.

  In this way, when the operator operates the touch input unit 6 to print the displayed information on the recording paper 15 and issue it as a receipt, the information is stored in the recording paper storage unit 16 of the printer unit 3 in the apparatus main body 1. The roll-shaped recording paper 15 is sequentially fed between the printing unit 14a and the platen unit 14b of the printer unit 14, and printing information is sequentially printed on the fed recording paper 15 by the printer unit 14. The recording paper 15 printed at 14 is sequentially sent out above the printer unit 14.

  The recording paper 15 on which the information is printed by the printer unit 14 is guided to the lower side of the drip-proof shutter unit 18 by the recording paper guiding unit 19. That is, the recording paper 15 sent out from the printer unit 14 is sent between the plurality of guide ribs 24 of the recording paper guiding unit 19 and the inclined portion 21 b of the drip-proof shutter plate 21. At this time, the recording paper 15 is guided in contact with either the front end surface 24 a of the guide rib 24 or the inclined portion 21 b of the drip-proof shutter plate 21, and the front end surface 24 a of the guide rib 24 and the inclined portion of the drip-proof shutter plate 21 are guided. It is sent toward the tip of 21b.

  As described above, when the recording paper 15 is fed between the front end surface 24 a of the guide rib 24 and the tip end portion of the inclined portion 21 b of the drip-proof shutter plate 21, the drip-proof shutter plate is discharged by the discharge force of the fed recording paper 15. 21 is pushed up, the drip-proof shutter plate 21 rotates clockwise around the support shaft 22, and the tip of the inclined portion 21 b is separated from the front end surface 24 a of the guide rib 24.

  That is, the drip-proof shutter plate 21 is rotatably supported by the support shaft 22 at a position slightly deviated from the center of gravity position to the opposite side (right side in FIG. 6) to the inclined portion 21b. Due to the delicate weight balance of the plate 21, that is, the slight difference in weight of the drip-proof shutter plate 21, the recording paper discharge port 17 is rotated in the closing direction. Is in contact with the front end face 24a. For this reason, the recording paper 15 sent out from the printer unit 14 pushes up the inclined portion 21b of the drip-proof shutter plate 21 from the front end surface 24a of the guide rib 24 by its discharge force.

  As a result, the drip-proof shutter plate 21 rotates clockwise around the support shaft 22, and the tip of the inclined portion 21 b is separated from the front end surface 24 a of the guide rib 24, so that the tip of the inclined portion 21 b and the front end of the guide rib 24 A gap is formed between the recording paper 15 and the surface 24 a, and the recording paper 15 passes through the gap. The recording paper 15 that has passed through the gap is discharged from the recording paper discharge port 17 of the printer cover 13 to above the printer cover 13. The discharged recording paper 15 is issued as a receipt.

  On the other hand, in this electronic register, when a water droplet drips on the printer cover 13, the water droplet may enter the recording paper discharge port 17 of the printer cover 13. That is, since the printer cover 13 is disposed on the apparatus main body 1 so as to be inclined forward and downward, water droplets dripping on the upper surface of the printer cover 13 flow from the upper surface of the printer cover 13 toward the lower side, and are recorded. In some cases, the paper discharge port 17 may enter the inside of the printer cover 13.

  When water droplets enter the inside of the printer cover 13 from the recording paper discharge port 17 in this way, the water droplets that have entered the water are received by the drip-proof shutter plate 21 of the drip-proof shutter unit 18. That is, the drip-proof shutter unit 18 is rotatably supported by the support shaft 22 at a position slightly deviated from the center of gravity position to the opposite side (right side in FIG. 9) from the inclined portion 21b. The recording paper discharge port 17 is rotated in the closing direction by a delicate weight balance of the plate 21, and the tip end portion of the inclined portion 21 b of the drip-proof shutter plate 21 is in contact with the front end surface 24 a of the guide rib 24.

  For this reason, water droplets that have entered the inside of the printer cover 13 from the recording paper discharge port 17 drop on the inclined portion 21b of the drip-proof shutter plate 21, flow from the inclined portion 21b to the flat plate portion 21a, and enter the flat plate portion 21a. The flowing water droplets accumulate in the portion surrounded by the inclined portion 21b and the side plate portions 21c on both sides. The water drops are discharged to the outside of the device main body 1 by the water droplet discharge unit 20.

  In this case, the water droplet discharge unit 20 is a drainage channel provided between the cover case 25 covering the printer unit 14 and the inner wall of the device main body 1 except between the printing unit 14 a and the platen unit 14 b of the printer unit 14. It is. As a result, when the water droplets dropped on the drip-proof shutter plate 21 from the recording paper discharge port 17 flow down from the drip-proof shutter plate 21, they flow into the water droplet discharge unit 20 while avoiding the printer unit 14, and the water droplets that have flowed in. Is guided to the lower part of the device main body 1 by the water droplet discharge unit 20 and discharged from the lower part of the device main body 1 to the outside.

  As described above, according to this electronic register, the printer cover 13 provided in the apparatus main body 1 and printed out by the printer unit 14 that prints print information on the recording paper 15 is discharged to the outside of the apparatus main body 1. The recording paper discharge port 17 and a lower side of the recording paper discharge port 17 are rotatably provided, and the recording paper discharge port 17 is opened and closed so as to receive water droplets that have entered from the recording paper discharge port 17 and a printer.
