Description

  The present invention relates to writing in which a straight line can be drawn in the transport direction of a transportable writing sheet.

  Conventionally, on an electronic blackboard or drawing board that is configured to be transportable using a writing sheet that can be written and erased as many times as possible with handwritten characters and pictures, the user is required to draw a straight line in the transport direction. It was necessary to accurately align the tip position, end position, and length of a straight line drawn by operating the writing sheet.

  For example, in Patent Document 1, since it is necessary to separately prepare a ruler, a rail for fixing the ruler is provided on the display frame of the electronic blackboard.

  Also, in Patent Document 2, a separate crease device is prepared, and it is not necessary to provide a rail or the like on the display frame of the electronic blackboard as in the above-mentioned Patent Document 1, but it is dropped from the electronic blackboard while using the crease device itself. The electronic blackboard has a structure for holding the pen holder itself, making the pen holder movable in the left-right direction, making the pen holder movable in the vertical direction of the electronic blackboard, and holding the pen holder itself.

  Embodiments of a writing apparatus according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is an overall external view of an electronic blackboard apparatus as an embodiment of the writing apparatus of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. FIG. 4 is a control block diagram for explaining a schematic configuration of the electronic blackboard apparatus of FIG. 1, and FIG. 5 is a drawing pen attached to the pen holding unit of the positioning unit of FIG. FIG. 6A is a state diagram before the pen holding portion is retracted to the retracting portion provided at the upper end of the rail portion of the positioning portion in FIG. FIG. 7 is a state diagram after the pen holding part is retracted to the retracting part provided at the upper end of the rail part of FIG. 1, and FIG. 7 is an electronic blackboard implemented by putting 5 cm squares on the writing sheet of FIG. 1. It is a whole external view of an apparatus.

  First, the electronic blackboard apparatus 1 shown in FIG. 1 has a writing sheet 4 in which characters and pictures can be freely written and erased using a writing pen (not shown) inside a writing window 3 constituted by a display frame 2. Are arranged to be transportable. Here, as shown in FIG. 2, a four-screen working sheet (a sheet connected in an endless track shape) is adopted as the writing sheet 4.

  Further, a writing pen (not shown) is fixed to the vertical display frame 2 orthogonal to the traveling direction of the writing sheet of FIG. 1 (left-right direction toward FIG. 1), and a positioning unit for positioning the pen tip 5 is arranged. The positioning portion 5 includes a rail portion 5a using the display frame 2, a slide portion 5b movable along the rail portion 5a to an arbitrary position in a direction perpendicular to the traveling direction of the writing sheet 4, and the slide portion 5b. A pen holding portion 5c for holding a writing pen that can be moved integrally, a retracting portion 5d of a slide portion 5b for retracting the pen holding portion 5c outside the writing sheet 4, and the display frame 2 side closest to the rail portion 5a And a scale part 5e for the slide sheet moving distance, which serves as a guide for alignment of the slide part 5b, and a scale part for the moving distance of the writing sheet, which is provided in the display frame 2 in the seat travel direction. 5f etc. are provided.

  Furthermore, an electrical box 6 having an operation unit 6a for operating the electronic blackboard device 1 is provided below the display frame 2, and a printer 7 for recording the contents written on the writing sheet, the printer 7 Are provided with an arm 8 for fixing the electronic blackboard apparatus main body, a stand section 9 for supporting the electronic blackboard apparatus main body, a caster 10 for movably supporting the electronic blackboard apparatus main body, and the like.

  As shown in FIG. 2, the electronic blackboard apparatus main body shown in FIG. 1 uses a four-sided endless sheet for the writing sheet 4, and the writing sheet 4 in the display frame 2 is written behind the writing sheet 4 at the time of writing. A seat board 11 serving as an underlay for supporting the seat is disposed. The writing sheet 4 can be conveyed in the feed direction and the return direction by rotating four endless sheets over four rollers and rotating them. Of the four rollers, the moving roller 12 is electrically driven by a sheet motor 16 which is a stepping motor capable of accurate rotation control here, and transmits power using a driving belt, pulley, gear, etc. (not shown). doing. The other three driven rollers 13, 14, and 15 are driven to rotate as the writing sheet 4 is moved by the moving roller 12. Although not shown in FIG. 2, the driven roller 13 is provided with a sheet tension mechanism, and is urged so that a constant tension is always applied to the writing sheet 4.

  A reading line for reading image information written on the writing sheet 4 is provided on the rear side of the seat board 11. In this reading line, an optical reading unit 20 including a light source 17, a mirror 18, a lens 19, and a CCD (solid-state imaging device) that performs photoelectric conversion is disposed. That is, the light emitted from the light source 17 is reflected by the writing sheet 4, the written image is reflected by the mirror 18, and an image is formed on the CCD imaging surface of the optical reading unit 20 using the lens 19. Thus, the image written on the writing sheet 4 can be converted into an electric signal.

  As keys of the operation unit 6a shown in FIG. 3, a power key 21 for turning on / off the power of the electronic blackboard device 1, a feed / stop key 22 for starting movement in the feeding direction of the writing sheet, and inputting a stop during movement, A return / stop key 23 for starting movement of the writing sheet in the return direction and a stop input during movement, a cleaning key 24 for cleaning the head of the printer 7, a density key 25 for adjusting the read density of the read image, and a copy mode A copy mode key 26 for selecting the item, a copy stop key 27 for stopping the copy operation in the middle, a mode switching key 28 for switching the display content mode of the 7seg LED, and a numerical value for switching the display value of the 7seg LED at the 10th place × 10 Key 29, numeric value for switching the display value of 7seg LED at the first place × 1 key 30, and for starting copy operation A copy start key 31 is provided.

  Further, as the display LED of the operation unit 6a shown in FIG. 3, the power LED 32 that is turned on when the power is turned on, the error LED 33 that is turned on when a paper jam occurs, and the cleaning key 24 are pressed, and the printer head is being cleaned. When the cleaning LED 34 and the density key 25 that are lit are pressed and the dark LED 35 is lit, the image written on the writing sheet 4 is read at a high density, and when the thin LED 36 is lit, it is written on the writing sheet 4. This indicates that the read image is read at a low density. When both LEDs are turned off, it indicates that the reading is performed with normal mixing. When the copy mode key 26 is pressed and the additional mode LED 37 is turned on, it indicates that the previously copied one is copied. When the two-page aggregation mode LED 38 is turned on, the writing sheet 2 screens are A4 size 1 When the 4-page aggregation mode LED 39 is turned on, four screens are copied to one A4 size, and when the four-page continuous mode LED 40 is turned on, one screen is A4. It shows that copying is made to one size and a total of four copies are made on four consecutive screens.

  Further, in this embodiment, the mode switching key 28 described above is provided so that it can serve as both the moving distance setting means and the copy number setting means. A two-digit numerical value display is performed according to the lighting state of the copy number LED 41, the sheet movement distance LED 42, and the movement number LED 43 in FIG. That is, the display meaning of the 7seg LED 44 varies depending on the mode. For example, when the copy number LED 41 is lit, the copy number setting mode is set, and the 7seg LED 44 displays the copy number value. Further, when the sheet movement distance LED 42 is lit, it is a sheet movement distance setting mode. For example, the unit of the length of the movement distance is converted into squares this time. When the movement number LED 43 is lit, the sheet movement number is displayed in the sheet movement number setting mode which is a part of the sheet movement distance setting mode.

  As described above, the reason for setting the movement distance as the number of squares is to reduce the number of digits of the value to be set. In this way, by reducing the number of digits of the set value, it is possible to reduce the number of digits of the 7seg LED for display and prevent the operation unit 6a and the like from becoming large, and it is possible to prevent an increase in cost. In particular, in the case of the electronic blackboard device 1, as shown in FIG. 1, since the width is wide and the normal size is 100 cm or more, if the unit to be set is cm, a display of about three digits is required. Even if it is a size that fits in about two digits, if a writing sheet of a multi-surface type (here, four-surface type) is used, it exceeds 100 cm (here, the length of the four-surface writing sheet is 500 cm). However, it is necessary to display about 3 digits.

  Thus, in the present embodiment, as shown in FIG. 7 described later, it is also possible to use a writing sheet 4 in which squares are described. In addition to the above, the grid effect has an advantage for making it easier for a normal user of the electronic blackboard device to write characters and the like. In the case of FIG. 7, a 5 × 5 cm square is used. In this case, by setting the moving distance of the writing sheet by the number of squares, the set value can be reduced to 1/5 of the case of setting in cm. In other words, the moving distance of 495 cm that is actually necessary can be set with only two digits using two 7seg LEDs, and the entire area of the four writing sheets used in the electronic blackboard device 1 of this embodiment can be covered. The number can be reduced by one digit.

  3 is switched by pressing the mode switching key 28. The machine initial setting is a copy number setting mode in which the copy number LED 41 is lit, and when the mode switching key 28 is pressed, the sheet moving distance LED 42 and the moving number LED 43 are sequentially switched to light. Along with this, the mode and the 7seg LED 44 are also switched to values corresponding thereto.

  When changing the value of the 7 seg LED 44, a numerical value for switching the display value of the 7 seg LED at the 10th place × 10 key 29, a numerical value for switching the display value of the 7 seg LED at the 1st place × 1 key 30, respectively, is pressed to Can be changed.

  In the copy number setting mode, the machine initial setting value is 1, and each time the numerical value × 1 key 30 is pressed, the display value is incremented by 1 and the value after 9 returns to 1. When the number of copies can be set to 10 or more, the next to 9 is set to 0 and the next is switched to 1.

  Further, in the sheet heel movement distance setting mode, the initial machine value of the sheet movement distance setting value is 25 squares (25 × 5 cm = 125 cm) corresponding to squares for approximately one screen, and the numerical value × 1 key 30 is set. The display value of the number of digits of 7seg LED corresponding to each press is incremented by 1 and the next value after 9 is 0, and the next value is switched to 1. Further, there is no 0 display at the place of 10 by the numerical value × 10 key 29, the light is turned off next to 9, and then it is switched to 1.

  Further, in the movement number setting mode, the machine initial value of the sheet movement number setting value is 1, and each time the numerical value × 1 key 30 is pressed, the display value is incremented by 1 and the value after 9 returns to 1. However, 0 display is possible only when a number is input at the 10's place of 7segLED.

  As described above, in this embodiment, since the copy number setting means, the sheet movement distance setting means, and the sheet movement number setting means are used in common, it is possible to use the 7-segment LED 44 for displaying numerical values and display them individually. Compared with the case where the part is provided, the installation area and the parts cost can be greatly reduced.

  In this embodiment, the length of the movement distance is set in squares. However, the present invention is not necessarily limited to this, and may be set in general cm. Of course, it is also possible to configure such that the length is set differently from the grid, such as a fraction of a minute.

  In the above embodiment, the display means (7 seg LED) for displaying the sheet moving distance and the number of copies is also used for mode switching. However, the display means (for example, a liquid crystal display) capable of displaying numerical values is mounted. If it is done, it can be combined with this.

  Next, the configuration of the main control unit 45 that controls the electronic blackboard device 1 will be described with reference to FIG. The main control unit 45 shown in FIG. 4 is disposed inside the electrical box 6 shown in FIG. 1, and includes an optical reading unit 20, an operation unit 6a, a printer 7, a sheet motor 16, and the like, a light source (not shown), A light source lighting device or a power supply unit for supplying power to them is connected.

  The main control unit 45 includes a central processing unit CPU 46, a ROM 47 that stores a control program, a RAM 48 that stores image data and other setting values (parameters) temporarily or until rewriting, an image A gate array 49 for processing data and the like, and a buzzer 50 and the like are mounted as notification means for notifying the user by sound. Of course, the notification means is not limited to this, and a configuration may be adopted in which the user is notified of a certain state by lighting and displaying an LED or the like on the operation unit 6a. However, the notification by the buzzer sound has an advantage that it can be noticed even when looking away or not always looking at the display. For this reason, more preferably, a more reliable notification means can be obtained by adopting a combination of means such as a buzzer and an LED that appeals to both visual and auditory senses.

  Moreover, the pen holding part 5c in the slide part 5b of the positioning part 5 attaches the writing pen 51 to the curved part, positions the pen point at the position where the pen point contacts the writing sheet 4, and the user writes by hand. The pen 51 is used while being held. If the writing sheet 4 is moved by a predetermined distance in this state, a straight line 52 parallel to the sheet moving direction and having a length corresponding to the moving distance can be drawn accurately and easily.

  Further, as shown in FIG. 6A, a retracting portion 5d is provided at the uppermost end portion of the rail portion 5a of the positioning portion, and a slide portion 5b that can slide the rail portion 5a in the vertical direction and a pen at the tip thereof. When the holding portion 5c is retracted to the position as shown in FIG. 6-2, the pen holding portion 5c at the tip of the slide portion 5b protruding from the vertical writing window 3a (the protruding portion 5g) is eliminated, and the vertical It is possible to secure a straight portion of the direction writing window 3a. If the straight portion of the writing window 3a is used as a ruler for drawing a vertical line, it is possible to draw a beautiful vertical line.

  In addition, if the writing sheet 4 on which squares are printed in advance at predetermined intervals is used, an electronic blackboard apparatus 1 as shown in FIG. 7 can be configured, and the user can use the squares to make characters. In addition, when the moving distance of the writing sheet 4 that is a feature of the present invention is set and a straight line having a predetermined length is drawn, the sheet moving distance is not set in centimeters. By using this number, it is possible to also use a 2-digit 7seg LED setting display section used for setting the number of copies and the number of movements (see FIG. 3).

  The writing device (electronic blackboard device) according to the present invention is configured as described above, and after explaining the general operation based on FIGS. 1 to 7, further using the flowcharts of FIGS. 8 to 27. Detailed operation will be described.

  First, when the user selects the copy number setting mode with the mode switching key 28 of the operation unit 6a in FIG. 3, when the copy start key 31 is pressed, writing is performed along the mode displayed on the operation unit 6a. Copying of the image described on the sheet 4 is started. When the copy start key 31 is pressed, the CPU 46 of the main control unit 45 in FIG. 4 notifies the gate array 49 of the start of copying. At the same time, the CPU 46 moves the writing sheet 4 in the feeding direction by driving the sheet motor 16.

  When the feeding position of the writing sheet 4 reaches a predetermined reading start position, the image information read by the optical reading unit 20 starts to be sent to the gate array 49, and the printing operation of the printer 7 is started.

  As the seat motor 16, a stepping motor is used. Since this stepping motor rotates by a given pulse as is well known, the sheet moving distance is determined from the number of pulses applied to the sheet motor 16 depending on the ratio of pulleys and gears between the sheet motor 16 and the moving roller of the writing sheet 4. Can be easily obtained.

  The number of pulses applied to the sheet motor 16 varies depending on the selected copy mode. For example, in the case of a normal copy for one screen, a pulse for moving the writing sheet 4 by one screen is given to the sheet motor 16. In the two-page aggregation mode and the four-page aggregation mode, a pulse for moving two screens or four screens is given to the sheet motor 16.

  In the copy number setting mode, the writing sheet 4 can be moved by one screen in each direction by pressing the feed / stop key 22 and the return / stop key 23 once.

  In the movement distance setting mode, after the movement distance and the number of movements are set, the movement of the writing sheet 4 is started by pressing the feed / stop key 22 or the return / stop key 23. After the writing sheet basket 4 is moved in the feed direction or the return direction by the set moving distance set value, the end of the movement is notified, and the writing sheet 4 is stopped for a preset time. Then, before the end of the preset stop time (for example, one second in this case), the buzzer 50 notifies the start of movement of the seat motor 16, and after the stop time ends, the writing sheet 4 is sent / The writing sheet 4 is stopped by moving to the position before the stop key 22 or the return / stop key 23 is pressed, and the end of the movement is notified.

  Here, when the set number of times of movement is 1, the series of operations ends. When the set number of movements is two or more, since the stop time is also set in advance, the machine side notifies the start of movement of the seat motor 16 before the end of the stop time (for example, one second before). Is performed, and the movement of the writing sheet 4 is started in the same manner as the first time.

  The actual shooting method is as follows. The length and number of straight lines to be written are determined, and the mode switching key 28 is pressed to switch to the sheet movement distance setting mode, and the sheet movement distance and the number of movements are set. The length of the straight line to be written can be easily recognized because the writing sheet moving distance scale portion 5f is provided in the display frame 2 parallel to the traveling direction of the writing sheet 4.

  Therefore, the slide portion 5b is moved on the rail portion 5a, and the pen holding portion 5c at the tip thereof is set at an arbitrary position where a straight line is desired to be drawn. As shown in FIG. 5, the writing pen is placed on the curved portion of the pen holding portion 5c. 51, the pen tip is positioned at a position where the pen tip contacts the bookkeeping sheet 4, and the writing pen 51 is held by hand. When the return / stop key 23 is pressed once in this state, the writing sheet 4 moves by the set distance, so that a straight line having a desired length corresponding to the moving distance can be drawn firmly.

  After the writing sheet 4 is moved, the end of the movement is notified, and after stopping for a certain period of time, the movement starts again and returns to the original position. At this time, prior to the start of movement (for example, one second before), a notice of movement start of the writing sheet 4 is notified. Also, the end of movement is notified when returning to the original position. Therefore, the user stops holding the writing pen 51 and moves the pen away from the writing sheet 4 during the two notifications after moving by the moving distance and before starting moving again. To.

  If the pen is held, the line is continuously written, and it may be written twice or an extra line may be drawn. Therefore, in order to prevent this, after moving the set distance and before moving again, the user is clearly informed of the end of holding the pen, and the writing of the line is ended. To do.

  When the number of movements is set to 2 times or more, after drawing one line and separating the pen from the writing sheet 4, the pen holding part 5c is moved to a position where the second line is desired to be drawn. Prepare for the movement of the second writing sheet 4. Since the first drawing is completed and the movement is returned to the original position, the end of the movement is notified and also notified before the second movement is started (for example, one second before). Similarly, the writing pen 51 can be set on the pen holding portion 5c to perform drawing. The operations described above can be performed for a set number of times.

  When drawing is performed with the writing pen 51 set on the pen holding portion 5c, a straight line can be drawn by moving the writing sheet in either the feeding direction or the returning direction. As shown in FIG. 7, when the pen holder 5c that holds the writing pen 51 is on the left side of the writing window 3, the return / stop key 23 is always pressed to move the writing sheet 4 in the returning direction. However, it is desirable to draw a line. The reason is that it is possible to operate while looking at the written line and that the force to move the writing sheet 4 is not directly applied to the pen tip of the writing pen 51, thereby extending the life of the pen tip. Because it is possible.

  Further, when drawing a vertical line when creating a table or the like, as shown in FIGS. 6A and 6B, the slide portion 5b is retracted to the retracting portion 5d provided at the upper end portion of the rail portion 5a. Like that. As shown in FIG. 6A, since the pen holding portion 5c at the tip of the slide portion 5b protrudes from the writing window 3a (protruding portion 5g), it is an obstacle when drawing a line in the vertical direction. However, by retracting the pen holding portion 5c to the retracting portion 5d, it becomes possible to draw a beautiful vertical line by using the writing window 3a as a ruler in the vertical direction.

  First, in FIG. 8, when the operation of the writing device is started, various initialization processes are performed in step S1. As a specific example of the initialization process, the copy number setting mode is set as the initial mode, and the initial value of the copy number value is set to “1”. Thus, normally, the 7seg LED 44 of the operation unit 6a in FIG. 3 is in the copy number setting mode, and the number of copies 1 is displayed. Accordingly, it is not necessary to perform a special operation, and a writing device that is easy for the user to use can be provided.

  Furthermore, in step S1, an initial value of the movement distance is set. The initial value of the moving distance is set to the length of approximately one screen in the traveling direction of the writing sheet 4. As a result, it is possible to save the trouble of inputting the set value when creating a table or the like for one screen. In addition, since the length of one screen is known, an approximate register can be obtained when other values are set. For example, in this embodiment, 25 squares are set as shown in step S1. Thereby, the movement distance setting work is reduced, the movement distance setting value for one screen can be easily recognized, and the length of the straight line that the user himself wants to draw can be easily recognized.

  In step S1, an initial value for the number of movements is set. The initial value of the number of times of movement is set to one time on the basis of drawing one straight line.

  As described above, the initial value set in step S1 is initially set even after the power is turned off if a nonvolatile RAM is mounted in the main control unit 45 shown in FIG. Since the initial value is held, the same value can be used repeatedly unless the initial value is rewritten. In addition, when the user changes or the initial value set initially is not appropriate, the initial value can be changed according to the user. Step S1 in FIG. 8 merely illustrates an example of the initialization process, and various initial setting values other than the above can be set as necessary.

  In step S2 following the various initialization processes in step S1, the input switching control process is performed. In step S3, the sheet drive (movement) control process is performed. In step S4, the copy control process is performed. Other control processes after S4 are also called as subroutines.

  The input switching control process in step S2 of FIG. 8 is a subroutine for controlling input switching between the movement distance number setting mode and the copy number setting mode as shown in FIG. First, in step S20, it is determined whether or not it is the movement distance number setting mode. If it is not the movement distance number setting mode, it is determined that the copy number setting mode is set (step S201).

  In the copy number setting mode in step S201, the display in the copy number setting mode (copy number LED is ON, movement distance LED is OFF, movement number LED is OFF, the value is read from RAM and the copy number value is read with 7seg LED) is displayed. Then, the process proceeds to step S202. In step S202, it is confirmed whether or not the numerical value × 10 key 29 and the numerical value × 1 key 30 have been pressed. If they have been pressed, the display value of 7segLED is changed in step S203. Skip S203 and go to step S204. In step S204, it is determined whether or not the mode switching key has been pressed. If the key has been pressed, the process proceeds to step S205, and processing for shifting to the movement distance count setting mode is performed. That is, the copy number value currently displayed is stored in the RAM 48, and the mode is set to the movement distance count setting mode.

  Returning to step S20, in the case of the movement distance number setting mode, the process proceeds to step S21, and after entering the movement distance number setting mode, a key input relating to the movement distance number setting and a key for moving the writing sheet are performed. It is determined whether or not there is an input. If there is no input, the process proceeds to step S211 to perform processing for shifting to the copy number setting mode. In other words, the current values of ON / OFF of various LEDs enumerated in step S211, buzzer ON for notifying mode change, moving distance setting value, moving number setting value are stored in the RAM and stored in the RAM. The copy number setting value that has been copied is called and displayed on the 7seg LED 44, and the mode is set to the copy number setting mode. As described above, by performing the processing of step S21 and step S211, it is possible to prevent a user's erroneous operation, and it is possible to eliminate wasted time due to the erroneous operation. Moreover, the trouble of checking the mode every time it is used is eliminated.

  Returning to step S21, if there is an input, the process proceeds to step S22 to determine whether or not the copy start key 31 has been pressed. When the copy start key 31 is pressed, the process proceeds to step S211 described above, and a process for shifting to the copy number setting mode is performed. As described above, in step S22, step S211, and step S42 in FIG. 27, which will be described later, the user's erroneous operation is prevented, and unnecessary copy work is prevented, or the copy start key 31 is pressed to copy. By automatically shifting to the number setting mode, it is not necessary for the user to perform the mode changing operation, and the copying operation can be reduced.

  Returning to step S22, if the copy start key 31 has not been pressed, the process proceeds to step S23, where it is determined whether the moving distance setting is selected. If the movement distance setting is selected, the process proceeds to step S231, and the display at the time of the movement distance setting (the copy number LED is OFF, the movement distance LED is ON, the movement number LED is OFF, the value is read from the RAM, and 7segLED Is displayed, and the process proceeds to step S232. In step S232, it is confirmed whether or not the numerical value × 10 key 29 and the numerical value × 1 key 30 are pressed. If they are pressed, the display value of the 7seg LED 44 is changed in step S233. Skip S233 and proceed to step S234. In step S234, it is determined whether or not the mode switching key 28 has been pressed. If it has been pressed, the process proceeds to step S235, and processing for shifting to the movement number setting mode is performed. That is, the currently displayed moving distance setting value is stored in the RAM, and the mode is set to the moving number setting mode.

  If it is not the movement distance setting mode but the movement number setting mode in step S23, the process proceeds to step S24, and the display at the time of setting the movement number (copy number LED is OFF, movement distance LED is OFF, movement number LED is ON. Then, the value is read from the RAM, the number of movements is displayed with 7segLED, and the process proceeds to step S25. In step S25, it is confirmed whether or not the numerical value × 10 key 29 and the numerical value × 1 key 30 have been pressed. If they are pressed, the display value of the 7seg LED 44 is changed in step S26. Step S26 is skipped and the process proceeds to step S27. In step S27, it is determined whether or not the mode switching key 28 has been pressed. If the mode switching key 28 has been pressed, the process proceeds to step S28, and processing for shifting to the copy number setting mode is performed. The currently displayed movement number setting value is stored in the RAM, and the mode is set to the copy number setting mode.

  As described above, by performing the input switching control process in step S2, it is possible to reduce the number of parts used, reduce the size of the operation unit, and reduce the cost. In addition, the process of displaying the 7segLED value in step S201, step S205, step S211, step S231, step S235, step S24, and step S28 of the input switching control process in step S2, and the storing and calling process in the RAM are performed. This eliminates the hassle of setting a new copy number and adding a straight line to a table or writing a similar table on another page. , Work efficiency can be improved.

  Subsequently, as shown in FIG. 10, the subroutine for the sheet drive control process in step S3 in FIG. 8 performs movement control of the writing sheet 4, and the copy number setting mode and the movement distance count setting mode or the movement distance count. Even in the setting mode, the control is changed depending on the sheet feeding or sheet returning. That is, the sheet feed control or the sheet return control is basically the same control, but the sheet moving direction is different.

  When the sheet drive control is called in step S3 of the main routine of FIG. 8, the process jumps to the sheet drive control process of step S3, which is a subroutine of FIG. 10, and proceeds to step S30. In step S30, the sheet movement flag is checked to confirm whether or not the sheet is currently being moved. When the sheet movement flag is “0”, no sheet movement is performed. Further, when the sheet movement flag is “1”, the sheet is being moved. If the sheet basket movement has not been performed, the process proceeds to step S31 to check whether the feed / stop key 22 or the return / stop key 23 has been pressed. If any key is pressed, the process proceeds to step S32, the sheet movement flag is set to “1”, and the process proceeds to step S33. If any key is not pressed in step S31, the routine is exited. In step S30, the process also proceeds to step S33 when the sheet is moving.

  In step S33, it is determined whether the moving distance number setting mode or the copy number setting mode is selected. If the copy number setting mode is selected, the process proceeds to the normal sheet control process in step S38. This step S38 is a subroutine for controlling the movement of the writing sheet 4 in the copy number setting mode, but since it is not directly related to the contents of the present invention, only the outline will be described. That is, when the feed / stop key 22 or the return / stop key 23 is pressed once, the writing sheet is moved in each direction by one screen. And if it is pressed again during movement, it stops, and if it is further pressed, control is performed to resume movement.

  In the movement distance count setting mode, in step S34 and step S35, the return / stop key 23 or the feed / stop key 22 is already pressed to check whether the sheet moving operation is being performed. As a confirmation method, the value of the sheet return job counter or the sheet feed job counter is checked. If the sheet return job counter is not 0, the process proceeds to the sheet return control process of step S39, which is a subroutine.

  If the sheet feed job counter is not 0, the process proceeds to the sheet feed control process in step S40, which is a subroutine.

  If the values of both the sheet return job counter and the sheet feed job counter are 0, the process proceeds to step S36 and step S37, and it is determined whether the return / stop key 23 and the feed / stop key 22 have been pressed. If the stop key 23 has been pressed, the process proceeds to a subroutine for sheet return control in step S39. When the feed / stop key 22 is pressed, the process proceeds to a sheet feed control subroutine in step S40. If the key is not pressed, confirmation is repeated until it is pressed.

  Next, the subroutine for sheet return control in step S39 in FIG. 10 will be described. FIG. 11 is a subroutine for sheet return control. The sheet return control in step S39 is entered when the sheet return key is pressed in the movement distance count setting mode, and the sheet motor is driven to move the writing sheet by a set distance. Then, a stop time is provided, and further, a control for driving the sheet motor to return the writing sheet to the original position and a control for repeating the control a set number of times are performed. Further, the user is notified of the stop and movement of the seat motor 16 by a notification means such as a buzzer 50.

  When the sheet return control in step S39 in FIG. 11 is called, the process proceeds to step S391, where the sheet return job counter value is confirmed, and the process proceeds to the job indicated by the counter value. For example, if the sheet return job counter value is “0”, the process proceeds to the sheet return job 0 in step S392 in FIG.

  The sheet return job 0 in step S392 is a job that is performed immediately after the sheet return key is pressed, and processes step S3921. In this step S3921, the sheet motor 16 is turned ON in the return direction by the set value of the moving distance, the writing sheet is started to move in the return direction, and 1 is set in the sheet return job counter. Here, since 1 is set in the sheet return job counter, the process proceeds to the sheet return job 1 in step S393 next time.

  Subsequently, in step S393 of the sheet return job 1 shown in FIG. 13, it is determined in step S3931 whether or not the writing sheet has moved a set distance, and if it has not moved, repeated confirmation is performed. If the set distance has been moved, the process proceeds to step S3932, where 2 is set in the sheet return job counter, and the buzzer 50 is turned on to notify that the set distance has been moved. Here, since 2 is set in the sheet return job counter, the process proceeds to the sheet return job 2 in step S394 next time. Thus, by performing the sheet return job processing, it is possible to make the user recognize the timing at which the writing pen is separated from the pen positioning unit, and it is possible to describe a straight line for a set distance.

  As shown in FIG. 14, the sheet return job 2 in step S <b> 394 checks whether or not a fixed time (time from the stop to the advance notice of re-movement), e.g., 4 seconds has elapsed after stopping the sheet motor in step S <b> 3941. Continue until the second has elapsed. If this fixed time has elapsed, the process proceeds to step S3942. In this step S3942, 3 is set in the sheet return job counter, the buzzer 50 is turned on to notify the user of the start of moving the writing sheet again, and the user is notified. Here, since 3 is set in the sheet return job counter, the process proceeds to the sheet return job 3 in step S395 next time.

  As shown in FIG. 15, the sheet return job 3 in step S395 checks in step S3951 whether or not a predetermined time has passed since the re-movement start notice. Here, the fixed time is set to, for example, 1 second, and if 1 second has not elapsed, it continues until it elapses. If one second has elapsed, the process proceeds to step S3952, and it is determined whether the time required to return the writing sheet 4 to the original position is shorter when the sheet is returned or shorter when the sheet is sent. doing. As this determination method, it is confirmed whether or not the moving distance (set value) of the sheet exceeds half of the total length of the sheet. If the movement distance exceeds half of the total sheet length, the process proceeds to step S3953, and the sheet motor is turned on in the return direction (the total sheet length minus the distance corresponding to the movement distance setting value) to return to the original position. 4 is set in the return job counter. If it is determined in step S3952 that the movement distance is less than half of the total sheet length, the process advances to step S3954 to turn on the sheet in the feeding direction (in the direction opposite to the movement direction) by the movement distance setting value, and the sheet is returned to the original position. Return to the position and set 4 to the sheet return job counter. Since 4 is set in the sheet return job counter, the process proceeds to the sheet return job 4 in step S396 next time.

  In this way, by performing the processing of the sheet return jobs 0, 1, 2, and 3 (FIGS. 12 to 15), claims 2 and 3 can be realized. In addition, by performing step S3952 of the sheet return job 3, when performing the control to return the writing sheet to the original position, it is possible to automatically select the direction in which the distance can be shortened, and to return to the original position. Since the time can be shortened and the workability is improved, Claim 4 can be realized.

  As shown in FIG. 16, the sheet return job 4 in step S396 checks whether or not the writing sheet 4 has been moved to the original position in step S3961, and if not finished, repeatedly checks. When the movement is finished, the buzzer 50 is turned on to notify that the movement is finished in step S3962, and the process proceeds to step S3963. In step S3963, it is confirmed whether or not the movement for the set number of movements has been completed. If the movement has been completed, the process proceeds to step S3964, where the sheet return job counter and the sheet movement flag are set to 0, and the process ends. If the movement for the set number of movements has not been completed, the process advances to step S3965 to set the sheet return job counter 5. Since 5 is set in the sheet return job counter, the process proceeds to the sheet return job 5 in step S397 next time.

  As shown in FIG. 17, the sheet return job 5 in step S <b> 397 confirms whether or not a fixed time (time from the stop to the advance notice of re-movement), for example, 4 seconds has elapsed after the sheet motor is stopped in step S <b> 3971. Continue until 4 seconds have passed. If the certain time has elapsed, the process proceeds to step S 3972. In this step S 3972, 6 is set in the sheet return job counter, and the buzzer 50 is turned on and notified for the advance notice of the re-movement of the writing sheet. Here, since 6 is set in the sheet return job counter, the process proceeds to the sheet return job 6 in step S398 next time.

  As shown in FIG. 18, the sheet return job 6 in step S <b> 398 confirms whether or not a certain time has passed since the re-movement start notice in step S <b> 3981. For example, the fixed time is set to 1 second, and when 1 second has not elapsed, the operation is continued until it has elapsed. If 1 second has elapsed, the process proceeds to step S3982, and, similarly to step S3921 of sheet return job 0, the sheet motor is turned ON in the return direction by the set distance of the moving distance, the writing sheet is started to move in the return direction, and the sheet is returned. Set 1 to the job counter. Thereafter, the above-described sheet return job is repeatedly performed. When the determination in step S3963 of the sheet return job 4 is completed, the number of movements is set, the process of step S3964 is performed, and the process is completed.

  Thus, by performing the processing of the sheet return stubs 4, 5, and 6, Claim 6 can be realized. Further, by performing the processing of step S3932, step S3942, step S3962, and step S3972 of the sheet return control, the timing at which the user releases and holds the writing pen with respect to the pen positioning unit becomes clearer. Operability is improved. In particular, if multiple sheet movements are set, the user will be confused when starting to move the set distance for the second and subsequent sheets. The user can make preparations for sheet movement.

  Next, the subroutine for sheet feeding control in step S40 in FIG. 10 will be described. FIG. 19 is a subroutine for sheet feeding control. The sheet feeding control in step S40 is entered when the sheet feeding key is pressed in the movement distance number setting mode, the sheet motor is driven, and the writing sheet is moved by a set distance. Then, a stop time is provided, and further, a control for driving the sheet motor to return the writing sheet to the original position and a control for repeating the control a set number of times are performed. Further, the user is notified of the stop and movement of the seat motor 16 by a notification means such as a buzzer 50.

  When the sheet feeding control in step S40 in FIG. 19 is called, the process proceeds to step S401, where the sheet feeding job counter value is confirmed, and the process proceeds to the job indicated by the counter value. For example, when the sheet feeding job counter value is “0”, the process proceeds to the sheet feeding job 0 in step S402 in FIG.

  The sheet feeding job 0 in step S402 is a job performed immediately after the sheet feeding key is pressed, and processing in step S4021 is performed. In this step S4021, the sheet motor 16 is turned ON in the feeding direction by the moving distance setting value, the writing sheet is started to move in the feeding direction, and 1 is set in the sheet feeding job counter. Here, since 1 is set in the sheet feeding job counter, the process proceeds to the sheet feeding job 1 in step S403 next time.

  Subsequently, in step S403 of the sheet feeding job 1 shown in FIG. 21, it is determined whether or not the writing sheet has moved a set distance in step S4031, and if it has not moved, repeated confirmation is performed. If the set distance has been moved, the process proceeds to step S4032, where 2 is set in the sheet feed job counter, and the buzzer 50 is turned on to notify that the set distance has been moved. Here, since 2 is set in the sheet feeding job counter, the process proceeds to the sheet feeding job 2 in step S404 next time. Thus, by performing the sheet feeding job processing, it is possible to make the user recognize the timing at which the writing pen is separated from the pen positioning unit, and it is possible to describe a straight line for a set distance.

  As shown in FIG. 22, the sheet feed job 2 in step S404 confirms whether or not a fixed time (time from stop to notice of re-movement), for example, 4 seconds has elapsed after the sheet motor is stopped in step S4041. Continue until the second has elapsed. If this fixed time has elapsed, the process proceeds to step S4042. In this step S4042, 3 is set in the sheet feeding job counter, the buzzer 50 is turned on to notify the user of the start of moving the writing sheet again, and the user is notified. Here, since 3 is set in the sheet feeding job counter, the process proceeds to the sheet feeding job 3 in step S405 next time.

  As shown in FIG. 23, the sheet feed job 3 in step S405 confirms whether or not a predetermined time has elapsed since the re-movement start notice in step S4051. Here, the fixed time is set to, for example, 1 second, and if 1 second has not elapsed, it continues until it elapses. If 1 second has elapsed, the process proceeds to step S4052 to determine whether the time required to send the sheet to the original position is shorter or the time required to return the sheet is shorter. doing. As this determination method, it is confirmed whether or not the moving distance (set value) of the sheet exceeds half of the total length of the sheet. If the movement distance exceeds half of the total sheet length, the process proceeds to step S4053, and the sheet motor is turned on in the feed direction (the total sheet length minus the distance corresponding to the movement distance setting value) to return to the original position. Set 4 to the feed job counter. If it is determined in step S4052 that the movement distance is equal to or less than half of the total sheet length, the process proceeds to step S4054, and the sheet is turned on by the movement distance setting value in the return direction (the direction opposite to the movement direction). Return to the position and set 4 to the sheet feed job counter. Since 4 is set in the sheet feed job counter, the process proceeds to the sheet feed job 4 in step S406 next time.

  In this way, by performing the processing of the sheet feeding jobs 0, 1, 2, and 3 (FIGS. 20 to 23), claims 2 and 3 can be realized. Further, by performing step S4052 of the sheet feeding job 3, when performing the control to return the writing sheet to the original position, it is possible to automatically select the direction in which the distance becomes as short as possible until the original sheet is returned to the original position. Time can be shortened and workability is improved. Thus, claim 4 can be realized.

  As shown in FIG. 24, the sheet feeding job 4 in step S406 confirms whether or not the writing sheet 4 has finished moving to the original position in step S4061, and if not finished, repeatedly confirms. When the movement is finished, the buzzer 50 is turned on to notify that the movement is finished in step S4062, and the process proceeds to step S4063. In step S4063, it is confirmed whether or not the movement for the set number of movements has been completed. If the movement has been completed, the process proceeds to step S4064, where the sheet feed job counter and the sheet movement flag are set to 0, and the process ends. If the movement for the set number of movements has not been completed, the process advances to step S4065 to set the sheet feed job counter 5. Since 5 is set in the sheet feeding job counter, the process proceeds to the sheet feeding job 5 in step S407 next time.

  As shown in FIG. 25, the sheet feeding job 5 in step S407 confirms whether or not a certain time (time from the stop to the advance notice of re-movement), for example, 4 seconds has elapsed after the sheet motor is stopped in step S4071. Continue until 4 seconds have passed. If the predetermined time has elapsed, the process proceeds to step S4072. In this step S4072, 6 is set in the sheet feed job counter, and the buzzer 50 is turned on and notified for the advance notice of the re-movement of the writing sheet. Here, since 6 is set in the sheet feed job counter, the process proceeds to the sheet feed job 6 in step S408 next time.

  As shown in FIG. 26, the sheet feeding job 6 in step S408 confirms whether or not a certain time has passed since the re-movement start notice in step S4081. For example, the fixed time is set to 1 second, and when 1 second has not elapsed, the operation is continued until it has elapsed. If one second has elapsed, the process proceeds to step S4082, and, similarly to step S4021 of sheet feeding job 0, the sheet motor is turned on in the feeding direction by the set distance of the moving distance, the writing sheet is started to move in the feeding direction, and sheet feeding is performed. Set 1 to the job counter. Thereafter, the above-described sheet feeding job is repeated, and the determination is made at step S4063 of the sheet feeding job 4 to end the set number of movement times, and the processing at step S4064 is performed until the processing is completed.

  In this way, by performing the processing of the sheet feeding stubs 4, 5, and 6, Claim 6 can be realized. Further, by performing the processing of step S4032, step S4042, step S4062, and step S4072 of sheet feeding control, the timing at which the user releases and holds the writing pen from the pen positioning unit becomes clearer. Operability is improved. In particular, at the start of moving the set distance for the second and subsequent sheets when multiple sheet movements are set, the user is confused when the writing sheet starts moving. The person can prepare for the sheet movement.

  The copy control processing subroutine in step S4 in FIG. 8 will be described with reference to FIG. The copy control in step S4 in FIG. 27 determines whether or not the copy start key 31 has been pressed in step S41, and if not, repeatedly confirms until it is pressed. If the copy start key 31 is pressed, it is determined in step S42 whether or not it is a movement distance number setting mode, and if it is not in the movement distance number setting mode, a copy start control subroutine is performed in step S43. The copy start control in step S43 is a control for starting the actual copy process, but since it is not directly related to the contents of the present invention, a detailed description of the control operation is omitted. In step S42, in the case of the movement distance count setting mode, the copy start control in step S43 is skipped so that the copy operation is not performed.
