In such a case, for example, the reading unit of the handy copying machine using roll thermal paper is moved to a desired position while being brought into contact with the portion (reading target) to be copied shown in FIG. , You can copy the song title, etc.

[0005]

[Problems to be solved by the device]

 However, the above-mentioned device has the following problems. Since the operator copies the copy machine while manually moving it, it is difficult to move at a constant speed in a straight line, and the output character string may be wavy or cut off. Therefore, there is a demand for a self-propelled scan type small copying machine, but the self-propelled method requires a large number of motors and the like, which makes it difficult to reduce the size.

Therefore, the present invention has been made in order to solve the above-mentioned problems, and for example, provides an inexpensive small-sized copying apparatus that can easily copy one character string of a CD jacket without breaking the columns. With the goal.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned object, the present invention has a reading unit having a visual recognition unit configured to visually recognize an object to be read such as a character string and a reading unit extending in a direction intersecting the longitudinal direction of the window. A driving unit that drives the reading unit to move in the longitudinal direction of the window, a printing unit that prints the information that the reading target has read by the reading unit, and a path that passes through the printing unit. A transport device for transporting the print medium is provided, and the drive means and the transport device are driven by the same drive source.

[0008]

[Action]

 According to the present invention, a small copy device is placed on an object to be read (eg, a lyrics card), and the window is brought into contact with a desired line for copying on the object to be read while visually recognizing it through the visual recognition section. .. In this state, the reading means is driven by the driving means to read the object to be read. The read information of the read object is printed on the print medium (for example, tape) by the printing unit, and the print medium after printing is discharged to the outside of the copying apparatus. Since the reading means and the print medium conveying device are driven by the same drive source (motor), if there is a rotation fluctuation (for example, rotation delay) in the drive source, the delay is conveyed to the reading means. Since it is transmitted to the apparatus at the same time, the reading means is delayed, and at the same time, the conveying apparatus is also delayed. Therefore, the delay of print output is canceled and normal printing is performed.

【Example】

Hereinafter, the present invention will be described with reference to the illustrated embodiments. First Embodiment FIG. 1 (A) is an external perspective view of a compact copying machine HC according to an embodiment of the present invention, FIG. 1 (B) is a block diagram of a control system used in the compact copying machine, and FIG. A) and (B) show driving diagrams of a sensor or the like as a reading unit.

First, the external configuration of the small copying machine HC will be described with reference to FIG. As shown in FIG. 1 (A), a long window 2 which is an “elongated window portion” is formed on the lower surface of a housing 1 having an L-shaped side surface, and “long window 2” is formed along the upper portion of the long window 2. The sensor 3 which is the "reading section" of the "reading means" is moved left and right in the directions of arrows A ₁ and A ₂ . A shelf-shaped visible portion 4 made of a transparent member is formed in front of the housing 1, and when viewed from above, a printed character string R of a printed material 5 that is a "reading object" that is in contact with the lower surface of the housing. However, it is visible through the long window 2. When pressed down on the top surface of the housing 1, the sensor 3 is moved in the direction of arrow A ₁ to read the character string R, etc. When released, the sensor 3 is moved in the direction of arrow A ₂ and returned to the home position, and a predetermined time has elapsed. After that, a start button 6 is arranged to stop the rotation of the drive motor. On the right front side of the housing 1, there are provided an inversion button 7 for inverting the black and white of printed characters, and shade setting buttons 8a, 8b for setting a monochrome inversion reference according to the shade degree of the object to be read. There is. Below the buttons 7, 8a, 8b, a reading width setting knob 9 for setting the height range of characters to be read is arranged.

Next, the control block of the small copying apparatus HC will be described with reference to FIG. As shown in FIG. 1 (B), a sensor 3 composed of a CIS (Contact Image Sensor) in which 64 reading elements are arranged in a line in a row orthogonal to the longitudinal direction of the long window 2 has an analog signal of 0 to 0. It is connected to a CPU 61, which is a "control unit", via an A / D converter 62 for converting it into a 255 digital signal. The CPU 61 has a RAM 63 for temporarily storing the data read by the sensor 3, a ROM 64 for storing a program for controlling the entire apparatus, a driver 66 for driving a print head 65 as a "printing section", and a "printer". An interface 68 is connected for controlling the drive of the motor M, which is a "driving source", and for converting input signals from the switch 14 interlocking with the start button 6, the reversing button 7, the light and shade setting buttons 8a and 8b, and the reading width setting knob 9. Has been done.

Next, based on FIGS. 2A and 2B, the lateral movement of the sensor 3 and the feeding operation of the printing tape T will be described. 2A shows the switching when the sensor (not shown) is moved left and right, and FIG. 2B mainly shows the switching of the gear when printing the reduced / enlarged characters on the tape T. In both cases of FIGS. 2A and 2B, the sensor 3 and the tape T are driven by the motor M, which is the same drive source.

As shown in FIG. 2 (A), a switching gear 12 is meshed with the output gear 11 of the motor M. The switching gear 12 is attached to the other end of a lever 13 having a start button 6 attached to one end, and the lever 13 is biased by a spring S in the direction of arrow B. Therefore, the switching gear 12 is normally meshed with the relay gear 15, and when the start button 6 is pushed, the switching gear 12 is moved to the position indicated by reference numeral 12a, and the wire W is wound around the pulley 16a. Switched to 16 side. The wire W is hung between the two pulleys 17a and 17b, and the sensor 3 is attached thereto.

A large-diameter relay gear 19 is meshed with the output gear 11 via a small-diameter relay gear 18, and the relay gear 19 is meshed with a gear 20 a fixed to a tape feed roller 20. An auxiliary roller 21 for pressing is arranged above the tape feed roller 20. The tape feed roller 20 is meshed with a gear 23a fixed to a winding shaft 23 that winds the ink ribbon IR through a relay gear 22. The ink ribbon IR is supplied from an ink ribbon supply unit (not shown). A print head 65 and a platen roller 24 are arranged above the winding shaft 23. The ink ribbon IR is superposed on the tape T and passes between the print head 65 and the platen roller 24.

Next, the operation will be described. When the start button 6 is pressed, the switch 14 is turned on, the motor M is rotated, and the output gear 11 is rotated clockwise. On the other hand, when the start button 6 is pressed, the switching gear 12 is switched to the position shown by the reference numeral 12a, the wire drive gear 16 is rotated clockwise, and the wire W and the sensor 3 are driven in the arrow A ₁ direction.

On the other hand, if the start button 6 is released when the reading of a predetermined length is visually completed through the visual recognition unit (see FIG. 1), the switch 14 is turned off, but the motor is not operated for a certain period of time. The rotation of M is programmed to continue. When the start button 6 is released, the switching gear 12 is disengaged from the wire driving gear 16 and switched to the relay gear 15, and the wire driving gear 16 is driven by the relay gear 15 and rotates counterclockwise. By this counterclockwise rotation, the wire W and the sensor 3 are driven in the arrow A ₂ direction. By driving in the A ₂ direction, the sensor 3 returns to the home position.

The clockwise rotation of the output gear 11 causes the gear 20a to rotate counterclockwise via the relay gears 18 and 19 regardless of the state of the start button 6 and simultaneously feeds the tape T to the left. Then, the gear 23a is rotated counterclockwise via the relay gear 22, and the ink ribbon IR is wound around the winding shaft 23. Due to the gear ratio of these gears 20a, 22 and 23a, the tape T and the feeding speed of the ink ribbon IR are synchronized. Further, the feed speed of the sensor 3 in the A1 direction and the feed speed of the tape T are constant.

Next, the case of printing the “reduced character” or the “enlarged character” will be described with reference to FIG. Of the parts described in FIG. 1A, those not involved in the above operation are omitted to simplify the drawing.

As shown in FIG. 2B, a switching gear 25 is meshed with the output gear 11, and this gear 25 is normally meshed with the relay gear 19. The switching gear 25 is rotatably attached to one end of a lever 26, and when the lever 26 is pushed in, the switching gear 25 is moved to a position indicated by reference numeral 25a and is meshed with the first gear 27a. The second gear 27b, which is coaxially fixed to the gear 27a and has a slightly different number of teeth, is meshed with the gear 20a. That is, compared with a gear train [gear 11-25-19-20a-22-23a] when the lever 26 is not pressed, a gear train [gear 11-25-27a-27b-20a] when the lever 26 is pressed. 22-23a], the individual gear ratios are set so that the gears 20a and 23 rotate less.

With such a configuration, when the lever 26 is pushed in, the rotation of the gears 20 and 23 becomes slow, and the characters printed on the tape T are reduced characters which are horizontally reduced. If the gear ratio of the gears 19 and 27 is changed, the enlarged character can be printed in the same manner.

As described above, as shown in FIGS. 2A and 2B, the feeding of the sensor 3 and the feeding of the tape T are synchronized based on the rotation of one motor. A relatively inexpensive motor can be used without requiring precision in the rotation speed of the motor.

Second Embodiment The device shown in the second embodiment has the same external appearance as that of the first embodiment shown in FIG. 1A, and the electrical configuration shown in FIG. equal.

As shown in FIG. 3, the output gear 11 is meshed with a large-diameter gear 31a coaxially fixed with the small-diameter gear 31b, and the small-diameter gear 31b is large-diameter gear 32a coaxially fixed with the small-diameter gear 32b. Is meshed with. The small diameter gear 32b is meshed with the large diameter gear 33. The large-diameter gear 33 is meshed with the tape feed roller 20 and a gear 23a fixed to a winding shaft 23 that winds the ink ribbon. The gear 23a is meshed with the large diameter gear 12b side of the switching gear 12 formed by coaxially molding the large diameter gear 12b and the small diameter gear 12c. The relay gear 15 is formed by coaxially molding a small diameter gear 15a and a large diameter gear 15b. The large diameter gear 12b side of the switching gear is meshed with the small diameter gear 15a.

The upper end of the lever 13 is in contact with the slope 6 a of the push-down member formed on the start button 6. Further, the tape T is sent from the tape supply unit TS to the print head 45 and the tape feed roller 20 via the guide shafts G ₁ and G ₂ . The ink ribbon IR is sent from the ink ribbon supply unit IS to the take-up shaft 23 via the print head 45.

Next, the operation of the small copying apparatus HC of the first embodiment and the second embodiment will be described based on FIGS. 1A and 1B and FIGS. 3 and 4A and 4B. To do. First, as shown in FIG. 1A, the long window 2 of the small copying apparatus HC is brought into contact with the character string R (for example, ABC ...), which is desired to be copied on the printed matter 5. When the start button 6 is pressed in this state, the motor M rotates and the feeding of the sensor 3 and the tape T is started (step S1). The small diameter gear 12c of the switching gear is meshed with the gear 16b. In the sensor 3, the reading element 3a, which is a component of the sensor 3, reads the lower 1 dot shown in FIG. 4B (step S2). Here, the reading element group of the sensor 3 is composed of 64 elements in a vertical line, and the reading width L shown in FIG. 4B can be adjusted by sliding the reading width setting knob 9. The signal for one dot output from the sensor 3 is binarized into 0 to 255 by the A / D converter 62 and read.

Next, in step S3, the threshold value (dot width set by the reading width setting knob 9) is compared, and its magnitude is discriminated (step S3). If it is larger than the threshold value, "D = 0" (reversing switch off) or "D = 255" (reversing switch on) is input to the RAM 63 (steps S4 and S6), and if it is smaller than the threshold value, it is captured. The data is directly input to the RAM 63 (steps S5 and S6). In step S7, it is determined whether the dot input in step S2 is the 64th dot from the top. Here, for example, as shown in FIG. 4 (B), if the reading width is set to "L", the portion of the width 1 above it becomes D (data) = 0, so that it cannot be read. Is programmed to. The operations of steps S2 to S7 are repeated until the 64th dot is reached.

When the reading of 64 dots is completed in step S7, it is determined in step S8 whether or not the reverse button 7 is turned on. If it is inverted, the data stored in the RAM 63 is inverted (step S9), and, for example, as shown in FIG. 7A, "white characters on black background" is converted to "black characters on white background" and printed. .. At this time, the multivalued data read in step S6 is output to the driver 66 of the print head 65, which is binarized by comparison with a predetermined threshold value in the driver circuit, and the binarized data is printed. It is output from the head 65 (step S10). If the reverse button 7 is not turned on in step S8, printing is performed as it is (step S10). In the above steps S2 to S10, only the vertical line immediately after the reading start of the character string R is read and printed. By doing so, the capacity of the RAM 63 for storing the read dots can be reduced, which contributes to cost reduction.

Next, in step S11, it is determined whether or not the start button 6 is on (that is, being pressed). If it is on, the process returns to step S2, and the same operation as described above is repeated. If the start button 6 is not turned on, the rotation of the motor M is continued for a fixed time (step S12). That is, when the start button 6 is released, the reading of the desired character string R in FIG. 1 (A) is completed, but when the start button 6 is released, the lever 13 moves the spring S. The switch gear 12 is meshed with the relay gear 15a, and the wire drive gear 16 is rotated clockwise. This rotation causes the sensor 3 to move in the direction of arrow A2 and return to the home position.

With this configuration, the sensor can be operated in both “feed” and “return” directions even if the motor is rotating in one direction. Further, when the sensor 3 returns, the tape T is fed, and the printed portion of the tape T is fed to the tip of the cutter C (see FIG. 3) which is separated from the printed portion. At this time, the return speed of the sensor 3 is increased to reduce the time required for the return, and the ratio of the gears 12 to 15a and 15b and the rotation amount of the motor M are adjusted so that the feed amount of the tape T is appropriate. Is set.

Further, as shown in FIG. 7B, it is possible to set the margins l ₁ and l ₂ before and after the printed characters on the printed tape T ₁ to be equal. A flowchart of the modified example is shown in FIG. In this case, the sensor 3 reads "all" of the character string R of one line and stores all the read data in the RAM 63. However, in this case, it is necessary to increase the RAM capacity.

As shown in FIG. 5, when the start button 6 is pressed and the motor M is rotated, the sensor 3 is moved at the same time, a desired one line is completely read and stored in the RAM 63 (step S21). At this time, the tape T is prevented from being fed by a known clutch or the like. When the reading / storing of one line is completed, if the inversion button 7 is on, the data is inverted and one line is printed (steps S22, S23, S24). If the inversion button 7 is not on, 1 is left as it is. The lines are printed (step S24).

Further, the flow chart shown in FIG. 6 may be used. This flowchart is for the case where the black background is automatically detected and black and white are automatically inverted in the case of a black background.

As shown in FIG. 6, when the start button 6 is pressed, the motor M starts rotating (step S31), and the sensor 3 reads the character string R for one line (step S32). Here, as shown in FIG. 7C, one line corresponds to the leftmost first line to be read first when the printed matter 5 is printed on a black background with a white outline. It is determined whether or not both the uppermost and lowermost pixels in the first line are "black" (step S33). If both are "black", it is highly likely that the original is a black background, and therefore the original is set in the black-and-white reversal mode (step S34). If one of the uppermost part and the lowermost part is “black” or both are “white”, it is determined that the document is a white background. Next, in step S35, it is determined whether or not the black / white inversion mode is set (step S35). In the case of the black / white inversion mode, the data read in step S32 is inverted (step S36) and printed (step S36). S37). If the reverse mode is not set in step S35, the printing is performed as it is. Next, in step S38, it is confirmed whether or not the start button 6 is on. If not, the motor is stopped for a certain period of time (step S39), and then the motor M is stopped (step S40). If the start button 6 is turned on in step S38, the sensor 1 reads the next one-line original, and steps S35 to 38 are repeated (step S41).

Third Embodiment In this embodiment, the width of a character to be printed is narrowed (reduced character). First, the structure of the gear will be described with reference to FIG. Note that, in FIG. 8, the tape supply unit and the ink ribbon supply unit are not shown.

As shown in FIG. 8, the output gear 11 of the motor M is meshed with the relay gear 52 via the switching gear 51. The switching gear 51 is rotatably attached to one end of a lever 59, and the other end of the lever 59 is in contact with the lower slope of the pushing member 58a of the reduction button 58. The lever 59 is biased to the upper left by a spring S2. The intermediate gear 52 is meshed with a gear 20 that is integrally formed with a tape feed roller (not shown). The gear 20 is meshed with a gear 23 a that is integrally formed with the winding shaft 23 via a relay gear 54. The output gear 11 is meshed with the switching gear 12 via relay gears 55, 56 and 57.

Next, the operation will be described. The feed speed of the sensor 3 is a constant speed due to the gear train [11-55-56-57-12-16b].

The case where the reduction button 58 is not pressed is a normal font (see FIG. 9 (A ₁ )), and the gear train is [11-51-52-20-20-54-23a]. On the other hand, when the reduction button 58 is pressed, it is a reduction font (see FIG. 9 (A2)), and the gear train is [11-51-53-20-54-23a]. That is, as is apparent from these gear trains, the font is reduced according to the gear ratio of the gears 52 and 53.

[0038]

As described above, according to the present invention, the object to be read is visually recognized through the window portion to specify the copy desired position, and the reading unit reads and reads while the reading unit is self-propelled. Since the information is printed and output, only the desired line to be copied can be printed as it is on the object to be read without breaking the linear shape, for example. Further, since the reading means and the conveying device are driven by the same drive source, fluctuations in the rotation speed of the driving source (for example, rotation delay) change simultaneously in the reading means and the conveying device (movement speed and conveyance speed delay). ) Because of the limitation, normal characters and numbers are output on the printout.
