Description

  The present invention relates to a printer that performs printing using roll paper configured by winding paper around a core member.

  The thermal transfer printer generates heat by causing the thermal head to generate heat, melts ink on the ink ribbon with this heat, and transfers the ink to paper to perform printing. The thermal head is composed of a heating element. There are multiple types of ink ribbons and papers to be used depending on the print size, glossy / matte finish, sensitivity, etc. If the ink ribbon and paper are not of a predetermined combination, a preferable printing result cannot be obtained.

  However, the ink ribbon and paper are loaded into the printer separately. Therefore, there is a possibility that the ink ribbon and the paper are mounted on the printer with an incorrect combination. Using ink ribbons and paper in the wrong combination will not give the desired print results and may cause printer failure in some cases.

  Therefore, Patent Document 1 discloses a technique (hereinafter referred to as a conventional technique A) in which information on the type of ink ribbon is stored in an IC tag attached to the ink ribbon and a plurality of types of ink ribbons can be used based on the information. (Also called).

  Specifically, in the prior art A, information on the type of ink ribbon is stored in an IC tag attached to the ink ribbon used in the thermal transfer printer. When the ink ribbon is mounted on the printer, information on the type of ink ribbon is read from the IC tag. Based on the read information, a plurality of types of ink ribbons can be used. In this case, only the type of ink ribbon can be obtained.

  Therefore, in the prior art A, an IC tag having the type of paper (printing paper) as information is further provided on the paper. When the paper is loaded into the printer, information on the paper type is read from an IC tag attached to the paper. Based on this information, the ink ribbon and paper are prevented from being used in the wrong combination.

Japanese Patent No. 4273427 (FIG. 4)

  However, the prior art A has the following problems. In other words, since the printer of the conventional technique A can read out information on the paper type from the IC tag, it can be prevented from being used in an incorrect combination. However, the IC tag needs to be attached to each of a plurality of types of paper. For this reason, there is a problem that the price of each paper used by the printer is increased.

  The present invention has been made to solve such a problem, and an object of the present invention is to provide a printer capable of determining the type of paper without increasing the cost of the paper to be used. .

In order to achieve the above object, a printer according to one embodiment of the present invention performs printing using a roll paper configured by winding a paper around a cylindrical core member.

<Embodiment 1>
FIG. 1 is a diagram showing a configuration of a paper flange 1 for holding a roll paper 4 described later. FIG. 2 is a diagram illustrating a state when the pair of paper flanges 1 are mounted on the roll paper 4. Hereinafter, a state in which the pair of paper flanges 1 are mounted on the roll paper 4 is also referred to as a mounted state.

  First, the paper flange 1 will be described with reference to FIG. FIG. 1A is a side view of the paper flange 1. The paper flange 1 includes a disk 1a, a cylinder 1b, and a pair of paper crimping portions 2.

  FIG.1 (b) is a figure which shows the structure of the paper flange 1 seen from the disc 1a side. FIG. 1C is a cross-sectional view of the paper flange 1.

  Referring to FIGS. 1A, 1B, and 1C, the disc 1a is vertically coupled to the cylinder 1b. The disk 1a is provided with a hole 1d. The inside of the cylinder 1b is hollow. A hole 1e is provided on the side surface of the cylinder 1b. A hole 1d is provided at the end of the cylinder 1b.

  The pair of paper crimping portions 2 are coupled to each other by a spring 3 so that each paper crimping portion 2 can move along a predetermined direction. The predetermined direction is a diameter direction of a cylinder 1b (a core member 5 described later). A force is applied to each paper crimping portion 2 by a spring 3 in a direction away from each other (a direction spreading outward).

  The paper crimping part 2 includes a lever 2a and a crimping part 2b. That is, the pair of paper crimping parts 2 includes a pair of levers 2a and a pair of crimping parts 2b.

  The lever 2 a is for adjusting the position of the paper flange 1 when the pair of paper flanges 1 are mounted on the roll paper 4. The lever 2a protrudes from the hole 1d to the outside of the disc 1a.

  When the paper flange 1 is mounted on the roll paper 4, the crimping part 2 b applies pressure to (presses) the roll paper 4 (core member 5). That is, the crimping part 2b contacts the roll paper 4 (core member 5) in the mounted state. The crimping part 2b protrudes from the hole 1e to the outside of the cylinder 1b.

  Next, an operation when the pair of paper flanges 1 are mounted on the roll paper 4 will be described.

  FIG. 2A is a diagram illustrating a state before the paper flange 1 is attached to the roll paper 4. FIG. 2B is a diagram illustrating a state in which the paper flange 1 is mounted on the roll paper 4. FIG. 3 is a cross-sectional view of each part when the paper flange 1 is mounted on the roll paper 4. Hereinafter, a description will be given with reference to FIGS. 2 and 3.

  As shown in FIGS. 2A and 2B, the pair of paper flanges 1 are attached to the roll paper 4 so as to sandwich both ends of the roll paper 4. That is, the pair of paper flanges 1 are attached to the roll paper 4 and hold the roll paper 4.

  When the user releases the lever 2 a and tries to attach the paper flange 1 to the roll paper 4, the end of the crimping portion 2 b contacts the end surface of the roll paper 4. In this case, the paper flange 1 cannot be securely attached to the roll paper 4.

  When the user presses the pair of levers 2a so that the pair of levers 2a of the pair of paper crimping portions 2 are close to each other, the pair of crimping portions 2b is also moved so as to be close to each other.

  That is, as shown in FIG. 3A, each paper flange 1 is placed on the roll paper 4 until the end surface of the roll paper 4 comes into contact with the disk 1 a of the paper flange 1 with the pair of crimping portions 2 b close to each other. Attach to.

  It should be noted that when the user releases the pair of levers 2 a, pressure is applied to the pair of paper crimping portions 2 so that the pair of paper crimping portions 2 are separated from each other by the restoring force of the spring 3. Therefore, the pair of paper crimping portions 2 moves away from each other. Thereby, the paper flange 1 is attached to the roll paper 4 as shown in FIG. That is, the paper pressure bonding part 2 moves the paper pressure bonding part 2 and applies pressure to the core member 5 (roll paper 4).

  Hereinafter, the direction in which each of the pair of paper crimping portions 2 is separated from each other is also referred to as a separation direction.

  FIG. 3B is a cross-sectional view when the paper flange 1 is mounted on the roll paper 4. As shown in FIGS. 2A and 3A, the roll paper 4 is configured by winding a paper around a cylindrical core member 5. The roll paper 4 includes a core member 5. Specifically, the roll paper 4 is obtained by stacking a plurality of layers of paper wound in a roll shape on a cylindrical core member 5. The core member 5 is a paper core member for winding paper around the core member 5. The core member 5 has a long shape. In the present embodiment, the inner diameter of the core member 5 varies depending on the type of paper (for example, paper quality and thickness) wound around the core member 5.

  When the pair of paper crimping portions 2 move in the separating direction by the restoring force of the spring 3, each paper crimping portion 2 applies pressure to (presses) the core member 5 (roll paper 4). That is, the paper crimping part 2 applies pressure to the core member 5 from the inside of the core member 5 along the diameter direction of the core member 5.

  Thereby, the pair of paper crimping portions 2 holds (supports) the roll paper 4. At this time, the position of each paper crimping portion 2 is uniquely determined by the inner diameter of the core member 5.

  FIG. 4 is a diagram illustrating an example of the configuration of the printer 1000 according to the first embodiment of the present invention. The printer 1000 performs printing using the roll paper 4. The printer 1000 is, for example, a thermal transfer printer. The printer 1000 is not limited to a thermal transfer printer. The printer 1000 may be another type of printer that performs printing using the roll paper 4.

  FIG. 4 shows a state in which the roll paper 4 with the paper flange 1 attached is attached to the printer 1000. In FIG. 4, the disk 1a and the cylinder 1b are not shown in order to make the drawing easier to see.

  As shown in FIG. 4, the printer 1000 includes a pair of paper flanges 1, a sensor 60, a paper type determination unit 7, and a CPU (Central Processing Unit) 8 in FIG.

  The sensor 60 detects the position of the paper crimping unit 2 as will be described in detail later. The sensor 60 is provided inside the printer 1000.

  The sensor 60 includes sensors 6A, 6B, and 6C. Hereinafter, each of the sensors 6A, 6B, and 6C is also simply referred to as a sensor 6.

  The sensor 6 is, for example, a reflective optical sensor. The sensor 6 has a function of emitting infrared rays and a function of receiving infrared rays. When the sensor 6 emits infrared rays, if there is a reflection object in the emission direction of the infrared rays, the sensor 6 receives the infrared light reflected by the reflection object. Thereby, the sensor 6 detects that the reflecting object is nearby.

  On the other hand, if there is no reflecting object, the sensor 6 does not receive the emitted infrared light. Therefore, the sensor 6 detects that there is no reflecting object in the vicinity of the sensor 6. Thus, the sensor 6 can detect whether or not there is a reflector in the vicinity of the sensor 6.

  In the present embodiment, it is detected whether or not the paper crimping portion 2 exists in the vicinity of each sensor 6. The number of sensors 6 required is the same as the number of types of roll paper 4. In the present embodiment, as an example, three sensors 6A, 6B, and 6C are used as shown in FIG. 4 so that three types of paper constituting the roll paper 4 can be detected.

  Each of the sensors 6A, 6B, and 6C transmits an output signal to the paper type determination unit 7. The output signal is a signal indicating whether or not there is a reflector (paper crimping portion 2) in the vicinity of each sensor 6.

  The paper type discriminating unit 7 refers to the output signal received from each of the sensors 6A, 6B, 6C and detects where the paper crimping unit 2 is located. The paper type determination unit 7 transmits the detected position information indicating the position of the paper crimping unit 2 to the CPU 8.

  In addition, the position of the paper crimping | compression-bonding part 2 and the kind of paper are matched with the table etc. previously. Hereinafter, a table indicating the position of the paper crimping unit 2 and the paper type in association with each other is also referred to as a paper discrimination table.

  CPU8 discriminate | determines the kind of paper which comprises the roll paper 4 based on the position of the paper crimping | compression-bonding part 2 which the received positional information shows, and a paper discrimination | determination table.

  Note that the sensor 60 may have the function of the paper type determination unit 7. In this case, the printer 1000 does not include the paper type determination unit 7, and the sensor 60 detects the position of the paper crimping unit 2. And the sensor 60 discriminate | determines the kind of paper which comprises the roll paper 4 based on the position of the paper crimping | compression-bonding part 2, and a paper discrimination | determination table.

  Here, as an example, it is assumed that the core member 5 is thin and the core member 5 has a large inner diameter. For example, as shown in FIG. 4, it is assumed that the position of the inner end of the core member 5 is at the position L11. Further, it is assumed that the position of the paper crimping part 2 is such that the position of the end of the crimping part 2b is the position L11. In this case, among the sensors 6A to 6C, the sensor 6B detects that the paper crimping portion 2 exists in the vicinity of the sensor 6B.

  As another example, it is assumed that the core member 5 is thick and the core member 5 has a small inner diameter. For example, as shown in FIG. 4, it is assumed that the position of the inner end of the core member 5 is at the position L12. Further, it is assumed that the position of the paper crimping part 2 is such that the position of the end of the crimping part 2b is the position L12. In this case, among the sensors 6A to 6C, the sensor 6A detects that the paper crimping portion 2 exists in the vicinity of the sensor 6A.

  As described above, the sensor 60 according to the present embodiment detects the position of the paper crimping portion 2 that changes as the paper crimping portion 2 moves. Thus, since the position of the paper crimping part 2 changes due to the difference in the inner diameter of the core member 5 of the roll paper 4, the sensor 60 can detect the position of the paper crimping part 2. Further, the sensor 60 determines the type of paper constituting the roll paper 4 based on the position of the paper crimping portion 2 and the paper determination table.

  When the printer 1000 uses roll paper 4 composed of different types of paper, the roll paper 4 having different inner diameters is used according to the type of the paper. Thereby, it becomes possible to discriminate (detect) the type of paper constituting the roll paper 4 by the sensor 60 detecting the difference in the position of the paper crimping portion 2.

  According to the present embodiment, the IC tag or the like is not provided on the paper as in the prior art. Therefore, the printer 1000 according to the present embodiment can determine the type of paper without increasing the cost of the paper to be used. That is, the type of paper can be determined at a low cost. In other words, the type of paper can be determined at low cost.

  Conventionally, since the IC tag is provided on the paper, it is necessary to provide a circuit for receiving the IC tag on the printer side, which causes a problem that the price of the printer increases.

  On the other hand, according to the present embodiment, unlike the prior art, no IC tag or the like is provided on the paper, so that it is not necessary to provide an IC tag receiving circuit in the printer 1000. As a result, the cost of the printer can be reduced.

  According to the present embodiment, at least one paper flange 1 having the configuration of FIG. 1 for detecting the type of paper is sufficient for one printer. That is, of the pair of paper flanges 1, one paper flange 1 may be configured without the paper crimping portion 2. Therefore, it is possible to detect the type of paper at a low cost.

  Furthermore, according to the present embodiment, the user does not need to perform a special operation for each paper type, and only by attaching the paper flange 1 to the roll paper 4, the position of the paper crimping portion 2 is automatically set. Changes.

  The sensor 6 is not limited to a reflective optical sensor. The sensor 6 may be, for example, a transmissive sensor, a mechanical SW (switch), a magnetic sensor, or the like.

<Embodiment 2>
Hereinafter, a printer according to Embodiment 2 of the present invention will be specifically described with reference to the drawings.

  FIG. 5 is a diagram showing a configuration of the paper flange 9 according to the present embodiment.

  FIG. 6 is a view showing a state when the pair of paper flanges 9 are attached to the roll paper 4.

  First, the paper flange 9 will be described with reference to FIG. FIG. 5A is a side view of the paper flange 9. The paper flange 9 includes a disk 9a, a cylinder 9b, and a paper crimping portion 10.

  FIG. 5B is a diagram illustrating the configuration of the paper flange 9 viewed from the cylinder 9b side. FIG. 5C and FIG. 5D are cross-sectional views of the paper flange 9.

  Referring to FIGS. 5A, 5B, and 5C, the disk 9a is vertically coupled to the cylinder 9b. The inside of each of the disk 9a and the cylinder 9b is hollow. A spring 11 is connected to the bottom surface of the cylinder 9b.

  The shape of the paper crimping part 10 is a cylindrical shape. The paper crimping portion 10 is inserted into the hollow portion of the paper flange 9. The paper crimping part 10 is connected to a spring 11 so as to be movable along a predetermined direction. The predetermined direction is the longitudinal direction of the core member 5. A force is applied to the paper crimping portion 10 by a spring 11 in the direction of pushing the paper crimping portion 10 outward from the inside of the cylinder 9b.

  When pressure is applied to the paper crimping portion 10 from the outside of the cylinder 9b toward the inside of the cylinder 9b, the paper crimping portion 10 moves to the inside of the cylinder 9b as shown in FIG. If the pressure applied to the paper crimping portion 10 is eliminated in the state of FIG. 5D, the paper crimping portion 10 moves to the outside of the cylinder 9b by the restoring force of the spring 11 as shown in FIG. 5C.

  Next, an operation when the pair of paper flanges 9 are mounted on the roll paper 4 will be described.

  As described above, FIG. 6 is a diagram illustrating a state when the pair of paper flanges 9 are attached to the roll paper 4. FIG. 6A is a diagram illustrating a state before the paper flange 9 is attached to the roll paper 4. FIG. 6B is a diagram illustrating a state in which the paper flange 9 is mounted on the roll paper 4.

  FIG. 7 is a cross-sectional view of each part when the paper flange 9 is mounted on the roll paper 4. Hereinafter, a description will be given with reference to FIGS. 6 and 7.

  As shown in FIGS. 6A and 6B, the pair of paper flanges 9 are attached to the roll paper 4 so as to sandwich both ends of the roll paper 4. That is, the pair of paper flanges 9 are attached to the roll paper 4 and hold the roll paper 4.

  As described above, the roll paper 4 is configured by winding a paper around a cylindrical core member 5. Specifically, the roll paper 4 is obtained by stacking a plurality of layers of paper wound in a roll shape on a cylindrical core member 5. In the present embodiment, the length of the core member 5 in the longitudinal direction varies depending on the type of paper (for example, paper quality and thickness) wound around the core member 5.

  When the paper flange 9 is attached to the roll paper 4, the user presses the paper flange 9 until the end surface of the roll paper 4 contacts the disk 9 a of the paper flange 9. Here, the diameter of the core member 5 is slightly larger than the diameter of the paper crimping part 10.

  When the paper flange 9 is attached to the roll paper 4, the paper crimping portion 10 contacts the core member 5. In this state, when the user further presses the paper flange 9 toward the roll paper 4, the core member 5 presses the paper crimping portion 10 to the inside of the cylinder 9b as shown in FIG. 7B.

  When the paper flange 9 moves until the disk 9a of the paper flange 9 contacts the end face of the roll paper 4, the position of the paper crimping portion 10 is determined. In the paper pressure bonding part 10, the paper flange 9 (paper pressure bonding part 2) moves to apply pressure to the core member 5 (roll paper 4). That is, the paper crimping portion 10 applies pressure to the end portion of the core member 5 by moving along the longitudinal direction of the core member 5.

  At this time, the position of the paper crimping portion 10 is uniquely determined by the length of the core member 5. In the present embodiment, the length of the core member 5 is the length of the core member 5 in the longitudinal direction.

  FIG. 8 is a diagram illustrating an example of the configuration of the printer 1000A according to the second embodiment of the present invention. The printer 1000A is, for example, a thermal transfer printer. The printer 1000A is not limited to a thermal transfer printer. The printer 1000A may be another type of printer that performs printing using roll paper.

  FIG. 8 shows a state in which the roll paper 4 with the paper flange 9 attached is attached to the printer 1000A.

  As shown in FIG. 8, the printer 1000 </ b> A is different from the printer 1000 in FIG. 4 in that the printer 1000 </ b> A includes a pair of paper flanges 9 in FIG. 6A instead of the pair of paper flanges 1. Since the other configuration of printer 1000A is the same as that of printer 1000, detailed description will not be repeated.

  FIG. 8 shows that the position of the paper crimping portion 10 changes according to the length of the core member 5 in the longitudinal direction.

  In the present embodiment, the sensor 60 is provided in the vicinity of the paper flange 9 attached to the printer 1000A. In the present embodiment, the sensor 60 detects whether or not the paper crimping portion 10 exists in the vicinity of each sensor 6.

  The number of sensors 6 required is the same as the number of types of roll paper 4. In the present embodiment, as an example, as shown in FIG. 8, three sensors 6A, 6B, and 6C are used so that three types of paper constituting the roll paper 4 can be detected.

  Each of the sensors 6A, 6B, and 6C transmits an output signal to the paper type determination unit 7 as in the first embodiment. The output signal is a signal indicating whether or not there is a reflector (paper crimping portion 10) in the vicinity of each sensor 6.

  The paper type discriminating unit 7 refers to the output signal received from each of the sensors 6A, 6B, 6C and detects where the paper crimping unit 10 is located. The paper type determination unit 7 transmits the detected position information indicating the position of the paper crimping unit 10 to the CPU 8.

  In addition, the position of the paper crimping | compression-bonding part 10 and the kind of paper are matched with the table etc. previously. Hereinafter, a table indicating the position of the paper crimping portion 10 and the paper type in association with each other is also referred to as a paper discrimination table A.

  CPU8 discriminate | determines the kind of paper which comprises the roll paper 4 based on the position of the paper crimping | compression-bonding part 10 which the received positional information shows, and the paper discrimination | determination table A. FIG.

  Note that the sensor 60 may have the function of the paper type determination unit 7. In this case, the printer 1000A does not include the paper type determination unit 7, and the sensor 60 detects the position of the paper crimping unit 10. The sensor 60 discriminates the type of paper constituting the roll paper 4 based on the position of the paper crimping portion 10 and the paper discrimination table A.

  Here, as an example, it is assumed that the length of the core member 5 is short. For example, as shown in FIG. 8, it is assumed that the position of the end of the core member 5 in the longitudinal direction is at a position L21. Further, it is assumed that the position of the end portion on the spring 11 side of the paper crimping portion 10 is at a position L31. In this case, among the sensors 6A to 6C, the sensor 6A detects that the paper crimping portion 10 exists in the vicinity of the sensor 6A.

  As another example, it is assumed that the length of the core member 5 is long. For example, as shown in FIG. 8, it is assumed that the position of the end of the core member 5 in the longitudinal direction is at a position L22. Further, it is assumed that the position of the end portion on the spring 11 side of the paper crimping portion 10 is at a position L32. In this case, among the sensors 6A to 6C, the sensors 6A and 6B detect that the paper crimping portion 10 exists in the vicinity of the sensors 6A and 6B.

  As described above, the sensor 60 according to the present embodiment detects the position of the paper crimping portion 10 that changes as the paper crimping portion 10 moves. Thus, the position of the paper crimping part 10 changes due to the difference in the length of the core member 5 of the roll paper 4, and the combination of the sensors 6 that detect the presence of the paper crimping part 10 changes. Thereby, the sensor 60 can detect the position of the paper crimping part 10. Further, the sensor 60 determines the type of paper constituting the roll paper 4 based on the position of the paper crimping portion 10 and the paper determination table A.

  When the printer 1000 </ b> A uses the roll paper 4 composed of different types of paper, the roll paper 4 having a different length of the core member 5 is used according to the type of the paper. Thereby, it becomes possible to discriminate (detect) the type of paper constituting the roll paper 4 by the sensor 60 detecting the difference in the position of the paper crimping portion 10.

  According to the present embodiment, at least one paper flange 9 having the configuration of FIG. 5 for detecting the type of paper is sufficient for one printer. That is, of the pair of paper flanges 9, one paper flange 9 may have a configuration in which the paper crimping portion 10 is fixed to the cylinder 9 b without using the spring 11. Therefore, it is possible to detect the type of paper at a low cost.

  Furthermore, according to the present embodiment, the user does not need to perform a special operation for each paper type, and only by attaching the paper flange 9 to the roll paper 4, the position of the paper crimping unit 10 is automatically set. Changes.

  The sensor 6 is not limited to a reflective optical sensor. The sensor 6 may be, for example, a transmissive sensor, a mechanical SW (switch), a magnetic sensor, or the like.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.

  The present invention can be used as a printer that can determine the type of paper without increasing the cost of the paper to be used.
