[Prior Art]

 Conventionally, for example, some songs may be selected from a CD (compact disc) in which a plurality of songs are recorded and recorded on a cassette tape. In this case, it is convenient to record the recorded song name (memo) in the case of a pre-recorded cassette tape for later playback. The lyrics card, jacket, manual, etc., of the CD are generally printed with the recording number, song title, lyricist name, composer name, etc. recorded on the CD. In such a case, for example, the reading section of a handy copying machine using roll thermal paper may be moved to a desired position while being in contact with the portion of the lyrics card or the like to be copied, and the song title or the like may be copied. ..

Another method is to use a character tape creator that prints desired characters on a sticking tape and outputs it. For example, "Song title ○ × ○ × Lyrics △△ Composition □ ○" Characters and numbers such as "" may be input from an input device such as a keyboard, and the tape may be output.

As still another method, a character string on the surface of an object to be read is read by an image reader, the read data is taken into a personal computer, and a desired read portion of the object to be read is printed and output to a printer device. It may be cut into a tape.

[0005]

[Problems to be solved by the device]

 However, each of the above devices has the following problems. First, when using a handy copy machine, the operator manually moves the copy machine to make copies, so it is difficult to move at a constant speed in a straight line, and the output character string is wavy or distorted. There was something that happened.

Further, when a character tape maker is used, the operator needs to input hiragana from the keyboard, convert it into kanji, read the font data stored in the memory, and print it, which makes the input complicated. Since many electronic parts are used, the character tape making machine was expensive. In addition, when using a personal computer, the operator needed to perform an inconvenient operation such as using an image reader and cutting and making a thin tape.

Therefore, the present invention has been made to solve the above problems, and provides an inexpensive small-sized copying apparatus that can easily copy a character string of an object to be read such as a CD jacket without distorting it. The purpose is to do.

Another object of the present invention is to simplify the operation of the switch by starting the reading of the character string of the object to be read by the reading sensor in synchronization with the pulling out of the tape as the printing medium. I also made it possible to copy by operation.

[0009]

[Means for Solving the Problems]

 In order to achieve this object, a small copying apparatus of the present invention detects a movement of a pair of nipping rollers that nips a printing medium and is movable in a pulling direction of the printing medium. A detection switch, a reading unit for reading the character string of the object surface to be read based on the detection signal from the detection switch, and character string information of the object surface read by the reading unit is output to the surface of the printing medium. Printing means, and a connection means for driving the rotation of the sandwiching roller and the movement of the reading means at the same time as the detection signal of the detection switch.

[0010]

[Action]

 According to the small-sized copying apparatus of the present invention having the above-mentioned configuration, the reading unit such as an optical sensor, which is a reading unit, is placed on a character string of an object to be read (for example, a lyrics card), and the reading moving unit is used to The reading means is moved along the character string on the surface of the object to be read, and the character string information of the object surface to be read read by the reading means is output and printed on the surface of the print medium by the printing means. When the print medium is pulled out in a fixed direction, a pair of sandwiching rollers that sandwich it are pulled in the pulling direction. Then, the detection switch detects the movement of the sandwiching roller, and based on the detection signal, the reading means starts reading the character string on the surface of the object to be read, and the read character string information is printed by the printing means. The output is printed on the surface of the printing medium by the printing medium. At that time, the rotation of the sandwiching roller and the movement of the reading unit are synchronized by the linking unit at the same time as the detection signal of the detection switch.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external view of a compact copying apparatus 10 according to an embodiment of the present invention, and FIGS. 2 and 3 are schematic configuration diagrams of its internal structure. Further, FIG. 4 is a sectional view of a main part.

As shown in FIG. 1, the external appearance of the compact copying apparatus 10 is such that an elongated reading window 14 is provided on the lower surface of the front side of the main body 12 having an L-shaped side surface, and the reading window 14 is provided. An optical reading sensor 16 as a reading means is reciprocally movable along the window 14 and is anchored to a wire 20 stretched between pulleys 18a and 18b at both ends. The wire 20 is wound around a pulley 24 provided coaxially with a wire drive gear 22 on the way. The wire drive gear 22 and the pulley 24 are formed by inserting the wire drive gear 22 and the pulley 24 into a shaft 38 projecting from the rear wall of the main body 12, and between the wire drive gear 22 and the pulley 24. The interpositioned spring clutch 40 is configured to rotate idly when the reading sensor 16 moves to the end. As the reading sensor 16, a CIS (Contact Image Sensor) in which 64 reading elements are arranged in a line in a row perpendicular to the longitudinal direction of the reading window 14 is used.

On the other hand, the tape T, which is the medium to be printed, passes between the platen roller 26 and the print head 28, is sandwiched by a pair of tape feed rollers 30a and 30b, and is fed in a fixed direction. To explain this structure in detail, the mounting plate 81 of the pair of tape feed rollers 30a and 30b is attached to the rear wall of the main body 12 so as to be movable back and forth in the tape feeding direction along the rail 82, and The guide pin 83 protruding from the rear wall is loosely inserted into the long groove 84 of the mounting plate 81 extending in the tape feeding direction. One end of the mounting plate 81 is normally in a retracted state by a tension spring 85 attached to the rear wall, while the switch 54 that is turned on when the mounting plate 81 moves forward has a front end of the mounting plate 81. Located on the rear wall surface.

On the other hand, one roller 30b of the pair of tape feeding rollers 30a, 30b is attached along the arc-shaped guide groove 86 formed in the mounting plate 81 so as to be capable of separating and abutting with respect to the other roller 30a. The roller shaft 87 is pivotally attached to the other end of a link plate 88 whose one end is pivotally attached to the mounting plate 81. The other end of the tension spring 89 whose one end is locked to the roller shaft is anchored to the mounting plate 81, and the roller 30b is pressed against the other roller 30a by the urging force of the tension spring 89. It is configured to maintain the separated state. In the figure, 90 is a stopper when the roller 30b is in a separated state from the other roller 30a. A tape interlocking gear 32 is coaxially provided on one of the tape feed rollers 30a, and the interlocking gear 32 passes through the relay gears 34 and 36 when the tape feed roller advances due to the advancement of the mounting plate 81. It meshes with the wire drive gear 22.

An ink ribbon tape IR is inserted between the platen roller 26 and the print head 28 in a state of being overlapped with the print medium tape T, and the ink ribbon tape IR is on the output side of the ribbon take-up spool. It is supposed to be wound up on 42. The ribbon winding spool 42 is also coaxially provided with a ribbon winding gear 44, and the gear 44 is connected to the relay gear 36 via a relay gear 46.

A visible portion 56 made of a transparent member such as glass is formed on the upper surface of the front side of the main body 12 and is a "reading object" placed on the lower surface of the main body when viewed from above. The printed character string R of the printed matter P is visually recognized through the reading window 14. Further, an inversion button 58 for reversing the black and white of the printed characters and gray level setting buttons 60a, 60b for setting the black and white reversal reference according to the gray level of the object to be read are arranged on the upper front surface of the main body 12. Further, below the buttons 58, 60a, 60b, a reading width setting knob 62 for setting the height range of characters to be read is arranged.

Next, the control block of the compact copying apparatus 10 will be described with reference to FIG. As shown in FIG. 5, the reading sensor 16 is connected to a CPU 72 that is a “control unit” via an A / D converter 70 that converts an analog signal into a digital signal of 0 to 255. The CPU 72 includes a RAM 74 for temporarily storing the data read by the reading sensor 16, a ROM 76 for storing a program for controlling the entire apparatus, a driver 78 for driving the print head 28 as a "printing section", and a start button. A switch 54 interlocked with 50, an inversion button 58, gray scale setting buttons 60a and 60b, and an interface 80 for converting an input signal from the reading width setting knob 62 and the like are connected.

Next, the operation of the compact copying apparatus 10 configured as described above will be described. First, the apparatus main body 12 is placed so that the reading window 14 is located on a character string to be copied such as a printed matter. When the tape T is pulled, the mounting plate 81 is pulled together to move to the position shown by the solid line in FIG. 2, and the switch 54 is turned on, and at the same time, the tape interlocking gear 32 of the tape feed roller 30a meshes with the relay gear 34. To do. When the tape T is pulled in this state, the tape feed roller 30a rotates counterclockwise and the wire drive gear 22 rotates clockwise via the relay gears 34 and 36, so that the wire 20 and the reading sensor 16 are connected to each other as shown in FIG. Move in the direction of the middle arrow A. During that time, since the switch 54 is turned on, the character string information read by the reading sensor 16 is output and printed on the tape T surface via the print head 28. Then, during that time, the reading state of the character string may be visually confirmed through the visual recognition unit 56.

At that time, the feeding speed of the reading sensor 16 in the A direction matches the drawing speed of the tape T. Further, the rotation of the tape feed roller 30 a causes the ribbon winding gear 44 to rotate counterclockwise via the relay gear 46, and the ink ribbon IR is wound around the ribbon winding spool 42. Due to the gear ratio of these gears 32, 34, 36, 46, 44, the feeding speed of the ink ribbon IR is synchronized with the drawing speed of the tape T.

On the other hand, when the reading is completed and the tape T is pulled out and the hand is released, the mounting plate 81 returns to the original position by the urging force of the tension spring 85, the switch 54 is turned off, and the interlock gear The meshed state between 32 and the relay gear 34 is released. In this state, the reading sensor 16 can be freely moved to the left and right with a fingertip, so that the reading sensor 16 moved in the A direction can be returned to the home position.
