  The present invention relates to an image recording and erasing apparatus, and more particularly, to recording an image on electronic paper in which an image is recorded by changing a display color in a portion to which the electric field is applied when an electric field is applied with a display surface as a boundary. The present invention also relates to an image recording / erasing apparatus that performs erasing.

  In recent years, various recording / display media that can record images electronically and hold recorded images for a certain period have been developed. These recording / display media are thin like paper. It is called “electronic paper”. Various techniques are known for displaying an image on electronic paper, such as rotation of colored particles, electrophoresis, thermal rewritable, liquid crystal, electrochromy, etc. The mainstream is that in which an image is recorded by changing the display color of the applied portion of the electric field by applying.

  By the way, conventionally, recording of an image on electronic paper is generally performed via a computer connected to the electronic paper, and the image can be recorded by a direct writing operation on the display surface of the electronic paper. There wasn't.

In order to solve this problem, Patent Document 1 discloses a technique for recording characters, designs, or impressions on an electronic paper provided with an electronic ink layer whose color changes according to an electric field using a pen-type instrument. ing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Here, a case will be described in which the present invention is applied to an image recording and erasing apparatus for recording and erasing images for electronic paper that displays images by rotating colored particles.

  FIG. 1A shows an example of a state in which a handwritten image is recorded on electronic paper 30 using image recording / erasing apparatus 10 according to the present embodiment, and FIG. An example of a state where a handwritten image recorded on the electronic paper 30 is erased using the recording / erasing apparatus 10 is shown.

  As shown in the figure, in the image recording and erasing apparatus 10 according to the present embodiment, as an electronic paper capable of recording and erasing an image, an electric field is applied with a display surface as a boundary, thereby applying an electric field application portion. An electronic paper 30 including an electronic ink layer 32 on which an image is recorded by changing the display color is applied. Here, the electronic ink layer 32 is a layer made of electronic ink in which two-color particles 34 colored in white and black for each hemisphere are dispersed in a resin binder. The two-color particles 34 are subjected to an electric field when an electric field is applied. It has the property of changing the direction according to the direction.

  As shown in the figure, the image recording / erasing apparatus 10 is configured to be movable in a state in which the placement portion side electrode 12 on which the electronic paper 30 is placed and the end portion face the display surface of the electronic paper 30. And a recording / erasing main body 14 that is moved when recording and erasing an image on the electronic paper 30, and a power source 20 that supplies electric power to generate an electric field applied to the electronic paper 30. A main body side electrode 16 is provided at the tip of the recording / erasing main body 14, and a voltage is applied between the main body side electrode 16 and the mounting portion side electrode 12 by a power source 20.

  Here, the power supply 20 and the mounting portion side electrode 12 are electrically connected by a voltage application line 40, and the power supply 20 determines the mounting portion side electrode 12 in advance via the voltage application line 40. The voltage having the first voltage value is applied. The power supply 20 and the recording / erasing body 14 are electrically connected by two voltage application lines 42 </ b> A and a voltage application line 42 </ b> B, and the movement of the recording / erasure body 14 with respect to the display surface of the electronic paper 30. When the image recording function for recording an image is executed, a voltage having a predetermined second voltage value is applied from the power supply 20 to the recording / erasing main body 14 via the voltage application line 42A. When an image erasing function for erasing an image recorded on the display surface of the paper 30 by moving the recording / erasing main body 14 is executed, a predetermined third voltage value is applied from the power source 20 to the recording / erasing main body 14 via the voltage application line 42B. A voltage is applied.

  On the other hand, in the electronic paper 30 according to the present embodiment, the two-color particles 34 in the electronic ink layer 32 are charged so that the white side surface is negative and the black side surface is positive.

  For this reason, in the image recording / erasing apparatus 10 according to the present embodiment, the first voltage value, the second voltage value, and the third voltage value have the relationship of the third voltage value> the first voltage value> the second voltage value. Each voltage value is determined in advance. As a result, when the image recording function is executed, an electric field in the direction from the mounting portion side electrode 12 to the main body side electrode 16 is applied between the mounting portion side electrode 12 and the main body side electrode 16. Thus, an image is recorded with the black side of the two-color particles 34 within a predetermined distance range adjacent to the position of the main body side electrode 16 in 32 facing the surface side of the display surface of the electronic paper 30. Further, when the image erasing function is executed, an electric field in the direction from the main body side electrode 16 toward the mounting portion side electrode 12 is applied between the mounting portion side electrode 12 and the main body side electrode 16. Thus, the black side of the two-color particles 34 within a predetermined distance range adjacent to the position of the main body side electrode 16 faces the back side of the display surface of the electronic paper 30 and the image is erased. In the image recording / erasing apparatus 10 according to the present embodiment, as an example, 50V is applied as the first voltage value, 0V is applied as the second voltage value, and 100V is applied as the third voltage value.

  In the case where the white side surface of the two-color particles 34 is positively charged and the black side surface is negatively charged, the first voltage value, the second voltage value, and the third voltage value are set such that the second voltage value> the first voltage value. Needless to say, the voltage values are determined in advance so that the relationship of voltage value> third voltage value is satisfied.

  As described above, the placement portion side electrode 12 is connected to the main body side electrode 16 through the power source 20, thereby applying an electric field between the main body side electrode 16 and the display surface of the electronic paper 30 as a boundary. It is supposed to be.

And a cylindrical function switching unit 14B. The function switching unit 14B has approximately two-thirds of the axial length of the cylindrical central axis extending from one end (upper end in FIG. 2) of the gripping body 14A toward the inside, and the respective central axes coincide with each other. It is inserted so that it can rotate in the direction of arrow A in FIG.

  On the other hand, to the other end portion (the lower end portion in FIG. 2) of the gripping body 14A, the main body side electrode 16 is attached to the distal end portion, and an electrode support body 14C made of a conductor is fixed.

  Then, as shown in FIG. 3A, a plate-like shape electrically connected to the voltage application line 42A is provided at a predetermined position on the outer peripheral surface of the function switching unit 14B and in contact with the inner peripheral surface of the gripping body 14A. The terminal 13A and the plate-like terminal 13B electrically connected to the voltage application line 42B are attached to the inner peripheral surface of the gripping body 14A as shown in FIG. A plate-like terminal 15 electrically connected to the main body side electrode 16 is attached to a predetermined position that contacts the outer peripheral surface of the function switching unit 14B. Here, as shown in FIG. 3C, the terminal 15 is held in a position and a state in which the terminal 15 selectively contacts either the terminal 13A or the terminal 13B by rotating the function switching unit 14B. Is attached. Therefore, by rotating the function switching unit 14B in the direction of arrow A in FIG. 2, a state in which either the second voltage value or the third voltage value is selectively applied to the main body side electrode 16; As a result, the image recording function is set by setting the voltage of the second voltage value, and the image erasing function is set by setting the voltage of the third voltage value. Become.

  On the other hand, as shown in FIG. 2, the fitting side end of the function switching unit 14B in the gripping body 14A and the exposed portion of the outer peripheral surface of the function switching unit 14B can be executed by switching by the function switching unit 14B. A mark group M for clearly indicating which function is an image recording function or an image erasing function is printed.

  In the recording / erasing main body 14 according to the present embodiment, a mark having a predetermined shape (here, a triangular shape) is printed as the mark group M at the end of the gripper 14A on the insertion side of the function switching portion 14B. In addition, the printing position of the mark printed on the gripping body 14A when the voltage of the second voltage value is applied to the main body side electrode 16 with respect to the exposed portion of the outer peripheral surface of the function switching unit 14B. A mark that clearly indicates that the image recording function is executable (here, a mark indicated by an arrow and a kanji 'book') and a third voltage value with respect to the main body side electrode 16 A mark (in this case, an arrow that clearly indicates that the image erasing function is executable at a position corresponding to the printing position of the mark printed on the gripping body 14A when the voltage is applied. And Mark) and indicated by the kanji 'consumption' is printed.

  Next, a procedure for recording an image on the electronic paper 30 using the recording / erasing main body 14 will be described with reference to FIG.

  The user first places the electronic paper 30 on the placement portion side electrode 12, and then clearly states that the function switching portion 14B can execute the image recording function by the mark group M (FIG. 2). Rotate so that the state shown in FIG.

  Then, the user moves the recording / erasing main body 14 on the electronic paper 30 in a state where the arrangement side end of the main body side electrode 16 faces the display surface of the electronic paper 30 with the power source 20 activated. A line is recorded on the display surface of the electronic paper 30. That is, the electronic ink layer of the electronic paper 30 is obtained by bringing the main body side electrode 16, which has a lower potential than the placement portion side electrode 12, closer to the display surface of the electronic paper 30 placed on the placement portion side electrode 12. As a result, the black side of the two-color particle 34 in 32 faces the main body side electrode 16 side, so that a black line corresponding to the locus of the end of the main body side electrode 16 in the recording / erasing main body 14 is recorded on the display surface of the electronic paper 30. Is done.

  The images of lines, characters, marks, etc. recorded in this way are retained even when the power supply 20 is stopped.

  Next, a procedure for erasing an image from the electronic paper 30 using the recording / erasing main body 14 will be described with reference to FIG. Here, a case where the electronic paper 30 on which some image is recorded is placed on the placement portion side electrode 12 will be described.

  First, the user rotates the function switching unit 14B so that the mark group M clearly indicates that the image erasing function can be executed.

  Then, the user sets the recording / erasing main body 14 in the state where the power source 20 is operated and the erasing target on the display surface of the electronic paper 30 in a state where the arrangement side end of the main body side electrode 16 faces the display surface of the electronic paper 30. The image to be erased is erased by moving the image to be erased. In other words, the electronic ink layer of the electronic paper 30 is brought closer to the display surface of the electronic paper 30 placed on the placement unit side electrode 12 by bringing the main body side electrode 16 having a higher potential than the placement unit side electrode 12. As a result, the white side of the two-color particles 34 in 32 faces the main body side electrode 16 side, so that a white image corresponding to the locus of the end of the main body side electrode 16 in the recording / erasing main body 14 is recorded on the display surface of the electronic paper 30. As a result, the black image is erased.

  As described above in detail, in the present embodiment, the image recording function of recording an image by moving the recording / erasing main body in a state where the end portion faces the display surface of the electronic paper with respect to the display surface of the electronic paper. When executing the image erasing function for erasing the image recorded on the display surface of the electronic paper by executing the image recording function by moving the recording / erasing main body with the end facing the display surface of the electronic paper And applying to the electronic paper so that the direction of the electric field generated between the main body side electrode provided at the end of the recording / erasing main body and the placement side electrode on which the electronic paper is placed is reversed. Since the voltage application path between the power source for supplying electric power for generating an electric field, the main body side electrode, and the mounting portion side electrode is switched, an image electronically recorded on electronic paper by hand To record Which it had can be erased by (recording and erasing body).

  In the present embodiment, the voltage value of the voltage applied from the power source to the mounting portion side electrode is set as a first voltage value determined in advance, and the voltage value of the voltage applied from the power source to the body side electrode is The direction of the electric field is reversed by switching the voltage application path so that either the third voltage value higher than the first voltage value or the second voltage value lower than the first voltage value is obtained. The direction of the electric field can be reversed with a simple configuration.

  Furthermore, in the present embodiment, since the function that can be executed by the switching is clearly indicated as the image recording function or the image erasing function, misuse can be prevented.

  Note that the recording / erasing main body according to the present invention is not limited to the one described in the present embodiment (see FIG. 2), and for example, the form shown in FIG. 4A and the form shown in FIG. You can also 4A and 4B, parts having the same roles as those shown in FIG. 2 are denoted by the same reference numerals as those in FIG.

  The recording / erasing main body 50a shown in FIG. 4 (A) relates to the present embodiment only in that the diameter of the outer peripheral surface of the exposed portion in the function switching portion 14B is the same as the diameter of the outer peripheral surface of the gripping body 14A. This is different from the recording / erasing main body 14.

  On the other hand, in the recording / erasing main body 50b shown in FIG. 4 (B), the function switching unit 14B is inserted into the gripping body 14A (in the direction of arrow B in FIG. 4 (B)) according to the pressing operation on the top. According to the present embodiment, it is configured to be reciprocally movable, and is configured by two switch portions 52A and 52B in which one is most exposed when it is most inserted into the gripping body 14A. This is different from the recording / erasing main body 14.

  In the recording / erasing main body 50b, the voltage of the second voltage value can be applied to the main body side electrode 16 in a state where the switch portion 52A is pushed most, and conversely, the switch portion 52B is pushed most. In this state, a voltage having a third voltage value can be applied to the main body side electrode 16. In this case, since it can be determined that the pressed switch portion indicates a function that can be executed, the gripper 14A can be executed by switching by the function switching portion 14B. It is not necessary to print a mark for clearly indicating which function is the image recording function or the image erasing function.

  In these cases, the same effects as in the present embodiment can be obtained.

  In the present embodiment, the case where the recording / erasing main body 14 is always operated when the power source 20 is operated has been described. However, the present invention is not limited to this. For example, the recording / erasing main body 14 may be activated only when an operation for image erasing or an operation for erasing an image is performed.

  FIG. 5 shows a configuration example of a recording / erasing main body 50c according to this embodiment.

  The recording / erasing main body 50c shown in the figure is connected to the terminal 13A to which the voltage application line 42A is connected and the voltage application line 42B by rotating the function switching unit 14B about the central axis of the cylindrical shape. The point that the terminal 13B is selectively electrically connected to the terminal 15 is the same as that of the recording / erasing main body 14 according to the present embodiment.

  On the other hand, in the recording / erasing main body 50c, the terminal 15 is not directly connected to the main body side electrode 16, but is electrically connected to the conductor 14D fixedly arranged at a predetermined position inside the gripping body 14A. In the recording / erasing main body 50c, the electrode support 14C is provided integrally with the main body side electrode 16 so as to be movable in the axial direction of the central axis of the gripping body 14A (the direction of arrow C in FIG. 5). A cylindrical conductor 14E is erected on the opposite end portion (the inner end portion of the gripping body 14A) of the main body side electrode 16.

  In the vicinity of the end of the surface on which the conductor 14E of the electrode support 14C is erected, the other end of the expansion / contraction body 14F having one end attached to the expansion / contraction support 14G fixed inside the gripping body 14A. The parts are in contact. The stretchable body 14F biases the electrode support 14C outward in the axial direction of the gripping body 14A with a biasing force that is less than a predetermined level and near the predetermined level. On the other hand, the conductor 14E is not in contact with the conductor 14D when no force is applied from the outside to the arrangement site of the body side electrode 16 of the electrode support 14C. It is provided in a state in which it is in contact with the conductor 14D when a pressing force of the predetermined level or more is applied to a portion where the main body side electrode 16 of the support 14C is disposed.

  Therefore, in the recording / erasing main body 50c, as shown in FIG. 5B, the portion where the main body side electrode 16 of the electrode support 14C is disposed is pressed to a pressure higher than the predetermined level with respect to the display surface of the electronic paper 30. The main body side electrode 16 and the terminal 15 are electrically connected only when an operation for image recording or an image erasing operation is performed in the pressed state, and recording is performed only at this time. The erasing body 50c can be operated. Here, a spiral spring is applied as the expansion and contraction body 14F. However, the present invention is not limited to this, and it is possible to apply a biasing force to the electrode support 14C, such as a leaf spring, shape memory resin, and rubber. Any member can be applied.

  Thus, in this embodiment, the main body side electrode 16 is connected so that the main body side electrode 16 is connected to the voltage application point from the power source 20 only when a pressing force of a predetermined level or higher is applied to the end portion of the recording / erasing main body 50c. Since the expansion / contraction body 14F for urging 16 is provided, only when the end of the recording / erasing main body 50c is in contact with the display surface of the electronic paper 30 with a pressing force of a predetermined level or higher, Recording and erasing can be performed, so that erroneous recording and erasing can be prevented, and bleeding of the recorded image and erased image can be prevented.

  As a modification, the voltage application point is attached so that the main body side electrode 16 is connected to the voltage application point from the power source 20 only when a pressing force of a predetermined level or higher is applied to the end of the recording / erasing main body. Needless to say, it is also possible to provide a configuration in which a stretchable body is provided in such a manner. In this case, the same effect can be obtained.

  In the present embodiment, a common body side electrode 16 for image recording and image erasing is provided at one end of the recording / erasing body 14, and an image recording function and an image erasing function are performed by a switching operation by the function switching section 14B. However, the present invention is not limited to this. For example, a main body side electrode for image recording is provided at one end of the recording / erasing main body 14, and It can also be set as the form which provides the main body side electrode for image deletion at an edge part.

  FIG. 6 shows a configuration example of a recording / erasing main body 50d according to this embodiment.

  In the recording / erasing main body 50d shown in the figure, the electrode support 14H having the main body side electrode 16A attached to the tip end is fixed to one end of the gripping body 14A, and the main body side electrode 16B is attached to the tip end. An electrode support 14I is fixed to the other end of the gripping body 14A. The electrode support 14H and the electrode support 14I are also made of a conductor, like the electrode support 14C.

  Further, in the recording / erasing main body 50d, a columnar conductor 14J is erected on the end opposite to the portion where the main body side electrode 16A of the electrode support 14H is disposed (the inner side end of the gripping body 14A). A columnar conductor 14K is erected on the end of the electrode support 14I opposite to the position where the main body side electrode 16B is disposed (the inner side end of the gripping body 14A). Further, a cylindrical terminal 13A that is electrically connected to the voltage application line 42A and a voltage application line 42B that are electrically connected to the voltage application line 42A are located within the recording / erasing main body 50d and spaced apart from each other in the axial direction. And a cylindrical terminal 13B connected to the. Here, the terminals 13A and the conductors 14J and the terminals 13B and the conductors 14K are positioned at a predetermined distance from each other.

  Then, in the gripping body 14A, the electrical connection between the conductor 14J and the terminal 13A and the conductor 14K and the terminal are moved by gravity in the direction of arrow D in FIG. 6 according to the posture of the recording / erasing main body 50d. A moving body 14L configured by a conductor that switches electrical connection between 13B is provided.

  Therefore, in the recording / erasing main body 50d, as shown in FIG. 7 as an example, the moving body 14L is moved downward only by moving the recording / erasing main body 50d upside down. The convenience can be improved. In this case as well, as shown in FIG. 7B as an example, whether the function that can be executed by the switching is an image recording function or an image erasing function is clearly indicated (in the example shown in FIG. 7B). It is needless to say that misuse can be prevented by clearly indicating by printing the letters “letter” and “erase”.

  As a modification of this embodiment, the recording / erasing main body can be activated only when an operation for image recording or an operation for image erasure is performed by the user.

  FIG. 8 shows a configuration example of a recording / erasing main body 50e according to this embodiment. In the figure, the same components as those of the recording / erasing main body 50d shown in FIG. 6 are denoted by the same reference numerals as those in FIG.

  As shown in the figure, in the recording / erasing main body 50e, the electrode support 14H and the electrode support 14I are movable in the axial direction of the gripping body 14A (arrow E direction in FIG. 8) as compared with the recording / erasing main body 50d. Different points are provided.

  Here, in the vicinity of the end of the surface on which the conductor 14J of the electrode support 14H is erected, there is an extension body 14M in which one end is attached to the extension body support 14N fixed inside the gripping body 14A. The end is abutted. The stretchable body 14M biases the electrode support 14H outward in the axial direction of the gripping body 14A with a biasing force that is less than a predetermined level and near the predetermined level. On the other hand, the conductor 14J is not in contact with the terminal 13A in a state in which no force is applied from the outside to the arrangement site of the body side electrode 16A of the electrode support 14H. When the pressing force of the predetermined level or more is applied to the arrangement site of the main body side electrode 16A of the support 14H, it is provided in contact with the terminal 13A.

  On the other hand, in the vicinity of the end of the surface on which the conductor 14K of the electrode support 14I is erected, the other end of the elastic body 14O having one end attached to the elastic body support 14P fixed inside the gripping body 14A. The parts are in contact. This stretchable body 14O biases the electrode support 14I outward in the axial direction of the gripping body 14A with a biasing force below a predetermined level and in the vicinity of the predetermined level. On the other hand, the conductor 14K is not in contact with the terminal 13B when the force is not applied from the outside to the arrangement site of the body side electrode 16B of the electrode support 14I. It is provided in a state in which the terminal 13B is brought into contact with when the pressing force of the predetermined level or more acts on the arrangement site of the body side electrode 16B of the support 14I.

  Therefore, in this recording / erasing main body 50e, as shown in FIG. 8B as an example, the portion where the main body side electrode 16A of the electrode support 14H is disposed is pressed against the display surface of the electronic paper 30 at a predetermined level or higher. The main body side electrode 16A and the terminal 13A are in an electrically connected state only when an operation for image recording is performed while being pressed by pressure, and only at this time, the recording / erasing main body 50e is image-recorded. In the meantime, the image erasing is performed in a state where the arrangement portion of the main body side electrode 16B of the electrode support 14I is pressed against the display surface of the electronic paper 30 with a pressing force equal to or higher than the predetermined level. The main body side electrode 16B and the terminal 13B are in an electrically connected state only when the operation for the recording is performed, and the image erasing main body 50e is erased only at this time. It can be operated Te.

  Here, a spiral spring is applied as the expansion and contraction bodies 14M and 14O. However, the present invention is not limited to this, and a biasing force may be applied to the electrode supports 14H and 14I such as a leaf spring, shape memory resin, and rubber. Any member can be applied as long as it is possible.

  Thus, in this embodiment, the main body side electrode 16A is biased so that the main body side electrode 16A is connected to the terminal 13A only when a pressing force of a predetermined level or higher is applied to one end of the recording / erasing main body 50e. The elastic body 14M is provided, and the main body side electrode 16B is biased so that the main body side electrode 16B is connected to the terminal 13B only when a pressing force of a predetermined level or higher is applied to the other end of the recording / erasing main body 50e. Since the elastic body 14O is provided, image recording is performed only when one end or the other end of the recording / erasing main body 50e is in contact with the display surface of the electronic paper 30 with a pressing force of a predetermined level or higher. In addition, it is possible to perform erasing, and it is possible to prevent erroneous recording and erasing, and to prevent occurrence of bleeding on the recorded image and the erased image.

  As a modification of this, the expansion and contraction is performed so as to bias the terminal 13A so that the main body side electrode 16A is connected to the terminal 13A only when a pressing force of a predetermined level or higher is applied to one end of the recording / erasing main body 50e. A body is provided, and expansion and contraction is performed so as to bias the terminal 13B so that the main body side electrode 16B is connected to the terminal 13B only when a pressing force of a predetermined level or higher is applied to the other end of the recording / erasing main body 50e. Needless to say, the body may be provided. In this case, the same effect can be obtained.

  In the present embodiment, the voltage value of the voltage applied from the power supply 20 to the placement portion side electrode 12 is set to a predetermined first voltage value, and the voltage value of the voltage applied from the power supply 20 to the main body side electrode 16 is In the above description, the direction of the electric field is reversed by switching the voltage application path so that either the third voltage value higher than the first voltage value or the second voltage value lower than the first voltage value is set. The present invention is not limited to this. For example, the voltage value of the voltage applied to the main body side electrode 16 is fixed at a predetermined voltage value, and the voltage value of the voltage applied to the mounting portion side electrode 12 is Two types of voltage values, a voltage value higher than a predetermined voltage value and a voltage value lower than the predetermined voltage value, may be switched for each function of the image recording function and the image erasing function. Also in this case, the same effects as in the present embodiment can be obtained.

  In the present embodiment, the case where the white surface of the two-color particles 34 is negative and the black surface is charged so as to be positive has been described. However, the present invention is not limited to this. Alternatively, the two-color particles 34 may be charged so that the white side surface is positive and the black side surface is negative. In this case, the direction of each electric field at the time of executing the image recording function and the time of executing the image erasing function may be reversed from the present embodiment. Also in this case, the same effects as in the present embodiment can be obtained.

  In the present embodiment, the case where the second voltage value is set to 0 V and the first voltage value and the third voltage value are set to positive voltage values has been described. However, the present invention is not limited to this, For example, such that the first voltage value is 0 V, one of the second voltage value and the third voltage value is a positive voltage value, and the other is a negative voltage value, so that the first voltage value is an intermediate value. Any form may be used as long as it determines the first to third voltage values. Also in this case, the same effects as in the present embodiment can be obtained.

  In addition, the configuration of the image recording / deleting apparatus 10 according to the present embodiment (see FIGS. 1 to 3) is merely an example, and it is needless to say that the configuration can be appropriately changed without departing from the gist of the present invention.

  Further, the configuration of the above-described modification of the recording / erasing main body (FIGS. 4 to 8) is also an example, and it goes without saying that it can be changed as appropriate without departing from the gist of the present invention.
