The emitted light from the light source 42 is emitted. The image on the surface of the document A illuminated by the reading slit 41 passes through a condenser lens 43 provided above it and is optically read by a CCD temporary image sensor 44.

On the other hand, a circuit board 45 is arranged on the side surface of the reading / printing section 21, and the key and switch group shown in FIGS. 2 and 3 is also provided, the thermal head 27, the encoder 39, and the light source.
42, the image sensor 44, etc. are connected.

FIG. 1 shows the structure of an electronic circuit formed on the circuit board 45. In FIG. 1, reference numeral 51 denotes a control unit, which controls the ON / OFF signal from the power switch 11. As various key input operation signals from the key input unit 12,
A pulse signal corresponding to the amount of movement of the device body 10 from the encoder 39, that is, a movement amount detection signal is input. Then, the control unit 51 controls the gates G1 to G5 according to various key operation signals from the key input unit 12. A kana / kanji exchange unit 52 is connected to the gate G1. When the delimiter signal is output from the control unit 51 in response to the operation of the delimiter key 17 of the key input unit 12, the Kana / Kanji conversion unit 52 outputs the "Kana" of the key input character data stored in the key input buffer 12a.
A kanji character search corresponding to a character is performed. At this time, kanji characters are searched in the order of fixed phrase → idiom → single kanji, and the searched kanji is formed into a character pattern through a kanji pattern memory 53. On the other hand, among the key input data, the “kana” character data that does not require kanji conversion is transferred to the kana pattern memory 54 through the gate G2 by the operation of the non-conversion key 16 and converted into a character pattern. That is, the document information created by operating the key input unit 12 is patterned as document character data consisting of kana / kanji converted kanji and unconverted kana, and the document data is sequentially
It is displayed on the display unit 13 via the display buffer 55, and is transferred and stored in the print buffer 56 via the gate G4 every time the conversion key 15 and the non-conversion key 16 are operated.

On the other hand, the encoder pulse received by the photosensors 38a and 38b of the encoder 39 is supplied to the rotation direction detection unit 57. This rotation direction detector 57 is an encoder disc.
Individual photosensors 3 via 36 and fixed disc 36c
8a, 38b detects the rotation direction of the encoder disk 36, that is, the moving direction of the device body 10, from the encoder pulse received in a state where a time difference has occurred,
The detection signal is output to the control unit 51 as a normal rotation or reverse rotation signal of the encoder disk 36.

Here, FIGS. 5A and 5B show the encoder disk 36 and the fixed disk in the encoder 39, respectively.
In the figure, when the encoder disk 36 rotates in the normal direction (F), the slit 36a first overlaps the slit a of the fixed disk 36c, and then the slit 36b overlaps the slit b. Further, for example, when the encoder disk 36 is reversely rotated (R), its slit 36b first overlaps with the slit b of the fixed disk 36c,
Next, the slit 36a will overlap the slit a.

That is, when the apparatus body 10 moves in the X direction for reading, each encoder pulse is received in the order of the photosensors 38a → 38b, and when it moves in the Y direction for printing, the order of the photosensors 38b → 38a. Is received by.

FIG. 6 shows the circuit configuration of the rotation direction detecting section 57. When the encoder pulse is received in the order of photosensors 38a → 38b by the normal rotation of the encoder disk 36, the flip-flop FF1 is passed through the amplifier P1. When the encoder pulse is set and the encoder pulse is received in the order of photosensors 38b → 38a due to the reverse rotation of the encoder disk 36, the amplifier
Flip-flop FF2 is set via P2.

FIG. 7 shows the operation waveform of each part in the rotation direction detecting section 57. When the signal c becomes high level, the normal rotation detection, that is, the movement detection of the apparatus body 10 in the X direction is detected by the signal d.
When it becomes high level, reverse rotation detection, that is, the device main body 10
Is detected in the Y direction.

On the other hand, in FIG. 1, the encoder pulse received by one of the photosensors 38a of the encoder 39 is supplied to the controller 51 and output to the timing signal generator 58. The timing signal generator 58 receives an operation command based on the encoder pulse from the controller 51,
Generate CCD exposure timing signal of constant cycle,
Various timing signals such as a predetermined number of read timing signals, serial / parallel conversion signals, and clock pulses are generated in synchronization with the movement amount detection signal of the apparatus body 10 from the encoder 39. The CCD exposure timing signal output from the timing signal generator 58 is sent to the one-dimensional image sensor 44, the read timing signal is sent to the A / D converter 59, and the serial / parallel converted signal is sent to the serial / parallel converter 60.
Then, the clock pulse is sent to the address counter 61, respectively. The one-dimensional image sensor 44 reads the reflected light from the document A in synchronization with the CCD exposure timing signal,
Output to the / D converter 59. The A / D converter 59 converts the input signal into a monochrome binary signal according to the read timing signal and outputs it to the serial / parallel converter 60. The serial / parallel conversion unit 60 converts the input signal into a parallel signal in units of, for example, 8 bits by the serial / parallel conversion signal, and outputs the parallel signal to the memory unit 62. The write and read addresses of the memory section 62 are designated by the address counter 61.

Then, the image data read by the image sensor 44 and stored in the memory unit 62 outputs an operation signal corresponding to an encoder pulse from the control unit 51 after the image print key 18 of the key input unit 12 is operated. Then, the control unit 51 is sequentially operated.
Read through gate G5 by gate G3 and gate
It is output to the print buffer 56 via G4. When the normal rotation signal is not output from the control unit 51 to the print buffer 56, that is, when it is not in the reading state, the AND gate AND
The clock pulse synchronized with the encoder pulse from the timing signal generator 58 is input via the gate line, and the created document data or the read image data input via the gate G4 in synchronization with this encoder pulse is input to the thermal head 27 line by line. Forward.

Next, the operation of the compact copying machine having the above structure will be described with reference to the flowchart of FIG.

First, to create a desired document, the power switch 11 is operated to turn on the power. Then, the control unit 51 is
In ten unscanned states, that is, when the encoder pulse is not output, the document creation mode is automatically set.
Here, the user operates the key input unit 12 of the apparatus body 10 to sequentially input desired characters (step S1).

First, by operating the character input keys 14 to key in the document information to be created, the input document data is sequentially transferred to the key input buffer 12a. At the same time, the input document data is displayed on the display unit 13 via the display buffer 55 (step S2). Then, after inputting the desired document kana, when the delimiter key 17 is operated (step S3), kana /
In the Kanji conversion unit 52, from the beginning of the input character, the fixed phrase → the phrase →
Kana / Kanji conversion processing is performed in the order of single Kanji (step S4). Here, when the conversion key 15 is operated (step
S5), the converted kanji pattern is the kanji pattern memory 53
It is read out and transferred to the print buffer 56 via the gate G4 (step S6). On the other hand, when the non-conversion key 16 is operated without the delimiter key 17 being operated after key input of the above kana characters (steps S3 → S7), the key input data is stored in the kana pattern memory 54 via the gate G2. Given and converted to the corresponding hiragana character pattern, and
The data is transferred to the print buffer 56 via the gate G4 (step S8). By repeating the character input processing, kana / kanji conversion processing, and non-conversion processing in steps S1 to S8, a desired document is created and sequentially stored in the print buffer 56.

Next, the operation of printing the document data created by key input as described above will be described. When printing document data, first print the recording surface B on the printing surface HA2 of the device body 10.
Touch the top and move in the Y direction. Then the encoder
An encoder pulse is output from 39 to the control unit 51 (steps S1 → S9). Then, the control unit 51 inputs the reverse rotation detection signal d (see FIG. 7) corresponding to the movement of the apparatus body 10 in the Y direction from the rotation direction detection unit 57 (step S10),
The print mode is set, and the created document data written in the print buffer 56 at the time of creating the document is sequentially transferred to the thermal head 27 through the non-operation judgment of the image print key 18 (step S11), and the recording paper is recorded. It is printed on B (step S12). In this case, the print timing of the document data is the timing generator that synchronizes with the encoder pulse.
Controlled by clock pulses from 58.

On the other hand, in order to read the image data recorded on the document A, the read head surface HA1 of the apparatus body 10 is brought into contact with the document A surface and moved on the desired image data in the X direction.
Then, the encoder 39 outputs an encoder pulse to the control unit 51, and the rotation direction detection unit 57 causes the device body to
The normal rotation detection signal c (see FIG. 7) corresponding to the movement direction X of 10 is output (steps S1 → S9, S10). Here, the control unit 51 is set to the reading mode by inputting the normal rotation signal c. Then, the image data optically read by the image sensor 44 via the reading slit 41 and the condenser lens 43 in FIG. 4 is sent to the address counter via the A / D converter 59 and the serial / parallel converter 60. 61
Is written to the memory address in the memory unit 62 specified by the step S13, the read image data sequentially written in the memory unit 62 is turned on when the scanning signal is output from the control unit 51. Are transferred to the display buffer 55 via the gates G5 and G3, which are displayed on the display unit 13 (step S14).

After that, when printing the image data stored in the memory section 62, the printing surface HA2 of the apparatus main body 10 is brought into contact with the recording paper B and moved in the Y direction, as in the case of the document printing. Then, an encoder pulse is output from the encoder 39 to the control unit 51, and a reverse rotation detection signal d (see FIG. 7) corresponding to the movement of the apparatus body 10 in the Y direction is output from the rotation direction detection unit 57. The control unit 51 is set to the print mode again (steps S9 and S10). Here, when the image print key 18 is operated (step S11), the read image data stored in the memory unit 62 is transferred to the print buffer 56 via the gates G5, G3, and G4, and is transferred to the thermal head 27. It is output and printed on the recording paper B.

That is, the document creation mode, the image reading mode, and the printing mode of the compact copying machine are automatically set in accordance with the moving state of the apparatus body 10.

Here, an actual printing operation in the reading / printing unit 21 of FIG. 4 when printing the created document data and the image data will be described.

That is, when the printing surface HA2 of the device body 10 is moved in the direction of the arrow Y while contacting the recording paper B, the rubber rollers 19, 20b are reversely rotated (R) with the movement of the device body 10, and the rotation is in one direction. It is transmitted to the ribbon winding shaft 34 through the clutch 32 and the gears 32a and 33b, and further, the ink ribbon cassette.
It is transmitted to the take-up spool 23b in 22. This allows
The ribbon take-up spool 23b rotates to take up the thermal transfer ink ribbon 24 guided from the ribbon pay-out spool 23a through the ribbon loading opening 26. In this case, the ribbon take-up shaft 36 rotates in accordance with the movement amount of the apparatus body 10 so as not to cause a slip between the recording paper B and the ink ribbon 24 as the apparatus body 10 moves, and The ink ribbon 24 is lightly pressed against the recording paper B by the thermal head 27 which always has downward printing pressure by the compression spring 28b. In this case, the unused portion of the ink ribbon 24 is sent out from the feeding spool 23a of the ink ribbon cassette 22 as the apparatus body 10 moves, and the thermal head 27
The used portion after being thermally transferred is sequentially wound onto the winding spool 23b in the same cassette 22. By moving the apparatus main body 10 in the Y direction as described above, the created document data or the read image data transferred and stored in the print buffer 56 is sequentially printed on the recording paper B.

Therefore, according to the small-sized copying machine having the above structure, if the apparatus body 10 is moved in the X or Y direction on the document A or the recording paper B, and the rubber roller 19 is normally rotated (F) or reversely rotated (R), Since the moving direction is detected by the rotation direction detecting unit 57 via the encoder 39, the control unit 51 is automatically set to the image reading mode or the printing mode. There is no need for manual operation. In this case, when the rubber roller 19 does not rotate at all, that is, when the apparatus body 10 is completely stopped, no encoder pulse is output from the encoder 39, so the control unit 51 is set to the document creation mode which is neither the reading mode nor the printing mode. Like

[Advantages of the Invention] As described above, according to the present invention, the rotation direction of the roller, which is provided on one side surface of the apparatus body and rotates in response to manual scanning for reading or printing, is detected, and this rotation direction detecting means Since the operation mode is switched according to the moving direction of the apparatus body detected by the manual scanning, it is possible to automatically switch between the reading mode and the print mode without the need to perform the switching operation with the manual switch. Type electronic device can be provided.
