Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the scope of the present invention is not limited to the illustrated examples.

[0010] First, with reference to FIGS. 1 to 4, the apparatus configuration of the present embodiment will be described. As shown in FIG. 1, the cutting device 10 is a device that cuts (cuts) a planar medium such as a rectangle as a cutting object into a planar shape intended by the user. When the thickness of the medium is thick or the hardness of the medium is hard, there is a possibility that the cutter blade cannot sufficiently pierce the medium. For pre-check, the cutting device 10 tries to pierce (penetrate) the medium with the cutter blade and determines whether it can be sufficiently pierced. When it can be sufficiently pierced, the cutting device 10 cuts the medium into the planar shape intended by the user to generate a cut product. This prevents the cutter blade from performing the cutting operation to the end even though it cannot sufficiently pierce the medium, thereby consuming wasted time. In the present embodiment, an example in which paper 60 (FIG. 3) such as A4 paper is used as the medium will be described, but it is not limited thereto. As the medium, other media that can be cut with a cutter blade, such as a sheet such as resin, a seal, or leather, may be used.

[0011] The cutting device 10 is used by being communicatively connected to a PC (Personal Computer) 50 as an information processing device via wireless communication. The PC 50 is a desktop PC. The PC 50 includes a control unit, an operation unit, a display unit, a wireless communication unit, etc. (all not shown). Based on an operation input from the user via the operation unit, the control unit of the PC 50 performs processes of generating and editing cut data indicating the planar shape, position, etc. of the cut product intended by the user by the cutting device 10. The PC 50 also receives input of operation information regarding the cutting device 10 and displays display information regarding the cutting device 10.

[0012] The information processing device communicatively connected to the cutting device 10 is not limited to the PC 50. The information processing device communicatively connected to the cutting device 10 may be other information processing devices such as a smartphone or a tablet PC. Also, assume that the communication method of the wireless communication between the cutting device 10 and the PC 50 is Bluetooth (registered trademark). However, the communication method of the wireless communication is not limited to Bluetooth, and other communication methods such as Wi-Fi (registered trademark) may be used. Also, the communication connection between the cutting device 10 and the PC 50 is not limited to wireless communication, and may be wired communication. The wired communication is, for example, USB (Universal Serial Bus) wired communication via a communication cable.

[0013] Next, with reference to FIG. 2, the internal functional configuration of the cutting device 10 will be described. The cutting device 10 includes an MPU (Micro Processor Unit) 11 as a control unit, an operation unit 12, a storage unit 13, an indicator unit 14, a wired communication unit 15, a wireless communication unit 16, a cutting unit 17, a home position detection unit 18, a paper feeding unit 19, a paper feeding detection unit 20, a power supply unit 21, a voltage detection unit 22, a mounting table (base unit) 31, and a sheet 32.

[0014] The cutting unit 17 includes an X-axis motor 171, a Z-axis motor 172, a carriage 173, a cutter blade 174, and a blade rotation motor 175. The paper feeding unit 19 includes a Y-axis motor 191. The power supply unit 21 includes a resistor 211. The mounting table 31 includes a conductive portion 312 as a main body conductive portion. The sheet 32 includes a conductive portion 322 as a sheet conductive portion.

[0015] The MPU 11 controls each part of the cutting device 10. The MPU 11 has a CPU (Central Processing Unit) and a RAM (Random Access Memory). The CPU reads out a specified program among various programs stored in the storage unit 13, expands it in the RAM, and executes various processes in cooperation with the expanded program. The RAM is a volatile semiconductor memory, and a work area for temporarily storing various data and programs is formed. The operation unit 12 has various buttons, accepts the pressing input to each button from the user, and outputs the operation information to the MPU 11. The various buttons of the operation unit 12 are a position key for moving the position of the paper 60, a temporary stop button for cutting, a set button for the paper 60, a take-out button for the paper 60, and the like.

[0016] The storage unit 13 is a storage unit capable of reading and writing information such as a flash memory. The storage unit 13 stores various data such as cutting data and various programs. In particular, the storage unit 13 stores a cutting program P1 for executing a cutting process described later. The indicator unit 14 has a light-emitting unit such as an LED (Light Emitting Diode), and indicates various states of the cutting device 10 by lighting / extinguishing. The indicator unit 14 has, for example, a power lamp indicating power on / off. The indicator unit 14 turns on / off the light emission of the light-emitting unit according to the instruction of the MPU 11.

[0017] The wired communication unit 15 is an interface for wired communication of a communication standard such as USB. The MPU 11 transmits and receives information to and from an external device such as a PC 50 via the wired communication unit 15 and a communication cable. The wireless communication unit 16 has an antenna, a modulation / demodulation circuit, a signal processing circuit, etc., and is an interface for wireless communication of Bluetooth with an external device such as a PC 50. The MPU 11 transmits and receives information to and from an external device such as a PC 50 via the wireless communication unit 16.

[0018] The cutting unit 17 moves the cutter blade 174 mounted on the carriage 173 in the X-axis direction and the Z-axis direction in accordance with the instruction from the MPU 11 by driving the X-axis motor 171 and the Z-axis motor 172. The cutting unit 17 cuts (penetrates) the paper 60 attached to the sheet 32 placed (set) on the mounting table 31 or cuts it into a planar shape intended by the user by moving the cutter blade 174. Here, referring to FIG. 3, the paper 60 attached to the sheet 32 placed on the mounting table 31 and the X-axis, Y-axis, and Z-axis will be described.

[0019] The sheet 32 is used for the purpose of not damaging the mounting table 31 with the cutter blade 174 and placing the paper 60 in a normal position. The mounting table 31 is where the sheet 32 with the paper 60 attached is placed. The X-axis is taken as the main scanning direction when transporting the mounting table 31 (sheet 32, paper 60). The Y-axis is orthogonal to the X-axis and is taken as the transport direction (paper feed direction, sub-scanning direction) of the mounting table 31 (sheet 32, paper 60). The Z-axis is orthogonal to the XY plane and is taken as the direction in which the cutter blade 174 moves up and down with respect to the paper 60.

[0020] The X-axis motor 171 is a motor that drives the carriage 173 in the X-axis direction in accordance with the instruction from the MPU 11. The Z-axis motor 172 is a motor that drives the cutter blade 174 in the Z-axis direction in accordance with the instruction from the MPU 11. The carriage 173 is a movable part in the X-axis direction that mounts the cutter blade 174. The cutter blade 174 is a cutting tool made of a conductor such as metal for cutting the paper 60 having, for example, an oblique cutting edge at the tip. The blade rotation motor 175 is a motor that rotationally drives the cutter blade 174 around the axial direction of the cutter blade 174.

[0021] The origin position detection unit 18 is a position detection unit such as an optical sensor that detects whether the cutter blade 174 is at the origin position in the X-axis direction in accordance with the instruction from the MPU 11. The origin position detection unit 18 outputs the detection result of whether the cutter blade 174 is at the origin position to the MPU 11. The MPU 11 controls the position of the cutter blade 174 of the cutting unit 17 in the X-axis direction using the detection result of whether the cutter blade 174 is at the origin position.

[0022] The paper feeding unit 19 is a conveying unit that conveys the mounting table 31 on which the sheet 32 with the paper 60 attached is placed in the Y-axis direction by driving the Y-axis motor 191 according to the instruction of the MPU 11. The paper feeding detection unit 20 is a detection unit such as an optical sensor that detects whether or not the mounting table 31 on which the sheet 32 with the paper 60 attached is placed is fed (set) to the paper feeding port of the paper feeding unit 19 according to the instruction of the MPU 11. The paper feeding detection unit 20 outputs the detection result of the setting of the paper 60 to the MPU 11.

[0023] The power supply unit 21 adjusts the power supplied from an external power supply and supplies it to each part of the cutting device 10. The power supply unit 21 has an output terminal of GND (ground potential, 0 [V]) electrically connected to the cutter blade 174. Also, as shown in FIG. 4, the power supply unit 21 has an output terminal of a predetermined power supply voltage electrically connected to the conductive part 312 and the input terminal of the voltage detection unit 22 via a pull-up resistor 211. The voltage detection unit 22 is a voltage sensor that detects the voltage of the conductive part 312 of the mounting table 31 according to the instruction of the MPU 11. The voltage detection unit 22 outputs the detection result of the voltage to the MPU 11. As shown in FIG. 4, the mounting table 31 has a mounting table body 311 and a conductive part 312.

[0024] As shown in FIG. 3, the paper 60 has, on a plane, a cut area 61 and a determination area 62. The cut area 61 is an area for generating a cut product by cutting. The determination area 62 is a cut area for determining whether or not it is possible to cut the cut area 61 before cutting the cut area 61, and is an area unnecessary for the cut product. As shown in FIG. 4, the mounting table body 311 is the main body part of the mounting table 31, and for example, has a rectangular shape in plan view and is made of an insulating material. The conductive part 312 is a conductor disposed at the upper surface position corresponding to the determination area 62 on the mounting table body 311. That is, the determination area 62 is set as a position that overlaps the conductive part 312 when the paper 60 is disposed at the correct position with respect to the mounting table 31. Note that the conductive part 312 is provided, for example, at a position biased toward one of both ends in the longitudinal direction of the mounting table 31. Also, the area of the conductive part 312 is smaller than the area of the mounting table body 311.

[0025] The sheet 32 includes a sheet main body 321 and a conductive portion 322. The sheet main body 321 is the main body portion of the sheet 32 and has, for example, a planar rectangular shape. Since the sheet main body 321 is placed on the mounting table 31, it has a shape that fits within the planar shape of the mounting table main body 311. The sheet main body 321 is made of a soft insulating material so that the cutter blade 174 is not damaged when the paper 60 is cut, and an adhesive for attaching the paper 60 is applied to the upper surface.

[0026] The conductive portion 322 is arranged at a position overlapping (opposing) the conductive portion 312 and is a conductor penetrating in the Z-axis direction. The conductive portion 322 is electrically connected to the conductive portion 312 when the sheet 32 is placed at a normal position on the mounting table 31. The conductive portion 322 is made of a conductive material such as soft conductive rubber so that the cutter blade 174 is not damaged when the paper 60 is cut. That is, the determination area 62 is set as a position overlapping the conductive portion 312 via the conductive portion 322 when the paper 60 is placed at the correct position with respect to the mounting table 31 and the sheet 32. Note that the conductive portion 322 is provided, for example, at a position biased toward one end of both ends in the longitudinal direction of the sheet 32. Also, the area of the conductive portion 322 is smaller than the area of the sheet main body 321.

[0027] Here, when the cutter blade 174 is brought into contact with the conductive portion 322 in a state where the sheet 32 is placed at a normal position on the mounting table 31, the voltage detection unit 22 detects the GND of the conductive portion 312. In a similar state, when the cutter blade 174 is not brought into contact with the conductive portion 322, the voltage detection unit 22 detects the power supply voltage of the conductive portion 312.

[0028] Next, with reference to FIG. 5, the cutting process executed by the cutting device 10 will be described. In advance, the cutting device 10 and the PC 50 are communicatively connected by wireless communication. The PC 50 generates cutting data for cutting the paper 60 into the planar shape and position intended by the user, such as the planar shape (cutting shape) and position to be cut, and transmits it to the cutting device 10 in response to the operation input by the user. The MPU 11 of the cutting device 10 receives the cutting data including the planar shape and position to be cut from the PC 50 via the wireless communication unit 16, and stores the received cutting data in the storage unit 13.

[0029] Also, the user attaches the paper 60 to be cut to a predetermined position on the sheet 32. When the paper 60 is in the normal position on the sheet 32, the determination area 62 is arranged at a position overlapping (opposing) the conductive portion 322. Then, the user places the sheet 32 with the paper 60 attached thereon at a predetermined position on the mounting table 31. When the sheet 32 is in the normal position on the mounting table 31, the determination area 62 is arranged at a position overlapping (opposing) the conductive portion 312.

[0030] Then, the user sets the mounting table 31 on which the sheet 32 with the paper 60 attached is placed in the paper feed port of the paper feed unit 19. The user inputs a cut start instruction via the operation unit of the PC 50. The PC 50 transmits the input cut start instruction to the cutting device 10. In the cutting device 10, triggered by receiving the information of the execution instruction from the PC 50 via the wireless communication unit 16, the MPU 11 executes the cutting process according to the cutting program P1 stored in the storage unit 13.

[0031] First, the MPU 11 receives and completes (inputs) a cutting start instruction from the PC 50 (step S11). Then, the MPU 11 determines whether at least a part of the cut shape as cut data protrudes from the cut area 61 and is within the determination area 62 (step S12). That is, in the determination area 62, as will be described later, since the cut for pre-check in step S13 is executed regardless of the cut shape intended by the user, the MPU 11 determines whether there is a possibility that the cut product will not be in the shape intended by the user due to damaging the paper 60 with the cut for pre-check. If the cut product is damaged by the cut for pre-check, there is a high possibility that the cut will be in a shape different from the shape intended by the user, and as a result, there is a high possibility of wasting the paper 60.

[0032] When at least a part of the cut shape as cut data is within the determination area 62 (step S12; YES), the MPU 11 generates message data indicating that at least a part of the cut shape is within the determination area 62 and transmits it to the PC 50 (step S13). The message data indicating that at least a part of the cut shape is within the determination area 62 means that there is a possibility that the cutter blade 174 will cut the paper 60 into a shape different from the shape intended by the user, and as a result, there is a possibility of wasting the paper 60. Then, the cutting process ends. Corresponding to step S13, the control unit of the PC 50 receives the message data and displays it on the display unit.

[0033] When the cut shape as cut data is not within the determination area 62 (step S12; NO), the MPU 11 drives the cutting unit 17, the paper feeding unit 19, etc., conveys the paper 60, moves the cutter blade 174 to a position corresponding to the determination area 62 (i.e., a position overlapping the conductive part 312), and performs a cutting operation. That is, a cut for pre-check is executed (step S14). In step S14, further, the MPU 11 detects the voltage of the conductive part 312 by the voltage detection unit 22.

[0034] Then, the MPU 11 determines whether the voltage detected in step S14 is low (GND) (step S15). If the voltage is low (step S15; YES), it means that the determination area 62 of the paper 60 has been penetrated by the cutter blade 174 and has been cut normally. Therefore, the MPU 11 sets it to the cuttable state (step S16).

[0035] Then, the MPU 11 drives the cutting unit 17, the paper feeding unit 19, etc., conveys the paper 60, moves the cutter blade 174 to the position corresponding to the cutting area 61, and cuts the paper 60 based on the cutting data in the storage unit 13 (step S17). By step S17, a cut product is generated. Then, the cutting process ends.

[0036] If the voltage detected in step S14 is high (power supply voltage) (step S15; NO), the determination area 62 of the paper 60 has not been cut normally by the cutter blade 174. Therefore, the MPU 11 sets it to the uncuttable state (step S18). The MPU 11 generates message data indicating that it is in the uncuttable state, and transmits the message data to the PC 50 via the wireless communication unit 16 (step S19). Then, the cutting process ends. Corresponding to step S13, the control unit of the PC 50 receives the message data and displays it on the display unit.

[0037] As described above, according to the present embodiment, the cutting device 10 includes the sheet 32, the cutter blade 174, the mounting table 31, the voltage detection unit 22, and the MPU 11. The sheet 32 mounts the paper 60 and has the conductive portion 322. The cutter blade 174 cuts the paper 60. The mounting table 31 has the conductive portion 312 that can be electrically connected to the conductive portion 322, and the sheet 32 is mounted thereon. The voltage detection unit 22 detects the voltage generated in the conductive portion 312. The MPU 11 causes the cutter blade 174 to perform a cutting operation at a position (determination area 62) overlapping the conductive portion 312, and determines whether the cutter blade 174 can cut the paper 60 based on the voltage detected by the voltage detection unit 22 during the cutting operation.

[0038] Therefore, before performing a cut according to the cut data, it is possible to determine whether the cutter blade 174 can cut while fully piercing the paper 60. This can prevent the situation where, even though the cutter blade 174 has not fully pierced the paper 60, the cutting operation according to the cut data is executed until the end, consuming useless time. Furthermore, it is possible to prevent the occurrence of wasted paper 60 that is cut while the cutter blade 174 has not been fully pierced.

[0039] Also, the cutter blade 174 is grounded. The conductive part 312 has a power supply voltage applied thereto. The MPU 11 determines that the cutter blade 174 can cut the paper 60 when the detected voltage is GND. The MPU 11 determines that the cutter blade 174 cannot cut the paper 60 when the detected voltage is the power supply voltage. Therefore, the user can easily and accurately determine whether the cutter blade 174 can cut the paper 60 and whether the cutter blade 174 cannot cut the paper 60. Note that the configuration may be such that a power supply voltage is applied to the cutter blade 174 and the conductive part 312 is grounded. For example, one end of the resistor 211 in FIG. 4 may be electrically connected to the voltage detection part 22 and the conductive part 312, and the other end may be electrically connected to the GND output terminal of the power supply part 21. In this configuration, the cutter blade 174 is electrically connected to the power supply voltage output terminal of the power supply part 21. However, in this configuration, the cutter blade 174 to which the power supply voltage is applied is exposed. Therefore, when an external object (such as a user's finger) comes into contact with the cutter blade 174, there is a risk that an electric current will flow through the object. Thus, the configuration in which the cutter blade 174 is grounded and a power supply voltage is applied to the conductive part 312 is preferable.

[0040] Also, when at least a part of the cut shape is in the determination area 62 corresponding to the position of the conductive part 322 on the paper 60 as cut data, the MPU 11 notifies, by message display on the PC 50, that there is a possibility that the cutter blade 174 cuts the paper 60 into a shape different from the shape intended by the user, and as a result, the paper 60 may be wasted, and then ends the cutting process. For this reason, by the cutting operation in the determination area 62, it is possible to prevent waste of the paper 60 in advance and guide the user to take necessary measures. The measures here are, for example, changing the cut data.

[0041] Also, when the MPU 11 determines that the cutter blade 174 cannot cut the paper 60, the MPU 11 notifies, by message display on the PC 50, that the cutter blade 174 cannot cut the paper 60. For this reason, the user can recognize that the cutter blade 174 cannot cut the paper 60, and it is possible to guide the user to take necessary measures to make the cutter blade 174 able to cut the paper 60. The measures here are, for example, changing the paper 60 to a cutting object with a thickness that allows the cutter blade 174 to penetrate, replacing the cutter blade 174, and adjusting the mounting state of the sheet 32 or the paper 60 on the mounting table 31.

[0042] In the above description, an example in which the storage unit 13 such as a flash memory is used as the computer-readable medium of the program according to the present invention is disclosed, but the present invention is not limited to this example. As other computer-readable media, it is possible to apply a portable recording medium such as a ROM (Read Only Memory) or a CD-ROM. Also, a carrier wave is also applied to the present invention as a medium for providing the data of the program according to the present invention via a communication line.

[0043] Note that the description in the above embodiment is an example of the cutting device, the cutting determination method, and the program according to the present invention, and the present invention is not limited thereto.

[0044] For example, in the above-described embodiment, the MPU 11 of the cutting device 10 generates message data and transmits it to the PC 50 for display, but the present invention is not limited to this. For example, the cutting device 10 may be configured to include a display unit such as an LCD (Liquid Crystal Display) capable of displaying messages. In this configuration, the MPU 11 generates message data and displays it on the display unit of its own device.

[0045] Also, the determination area may be configured such that the user cannot set cutting data. For example, the control unit of the PC 50 executes a cutting data generation process for generating cutting data based on an operation input via an operation unit from the user. In the cutting data generation process, the control unit determines whether at least a part of the cutting shape enters the determination area as the cutting data based on the operation input. When at least a part of the cutting shape enters the determination area, the control unit displays a warning message on the display unit. The warning message is, for example, a message warning that at least a part of the cutting shape enters the determination area, and there is a possibility that the cut product will be cut into a shape different from the intended shape by the user, resulting in waste of paper. At this time, the control unit receives, for example, an operation input for creating corrected cutting data from the user via the operation unit. Alternatively, the control unit may be configured to end the process without setting the cutting data when at least a part of the cutting shape enters the determination area as the cutting data based on the operation input. That is, this configuration prohibits the creation of cutting data in which at least a part of the cutting shape enters the determination area.

[0046] Although the embodiments of the present invention have been described, the scope of the present invention is not limited to the above-described embodiments, but includes the scope of the invention described in the claims and the equivalent scope thereof.
