As shown in detail in FIGS. 2 to 6, the base 20 and the exterior
A side plate 22 is provided in the housing 10 of the recording apparatus constituted by 21.
23 are provided, and main rollers 24 and 25 are rotatably disposed on the side plates 22 and 23 of the side plates 22 and 23 in a substantially horizontal state and at positions slightly apart from each other. The platen roller 26 is arranged in pressure contact with the main rollers 24 and 25 from above.
The shape connecting the central points of the rollers 24 to 26 is in a triangular state, and the two sides of the triangle passing through the contact points between the platen roller 26 and the lower main rollers 24, 25 are inclined surfaces. The normal line at this contact point is the conveying direction of the recording paper 14 when each roller is rotated. As is apparent from FIGS. 6 (A) and 6 (B), the three rollers 24, 26, 27 are drivingly connected by a sub-scanning moat (pulse motor) 30 via gears 24a, 26a, 27a, and the peripheral speed is It is possible to perform synchronous drive in which Further, the roller outer peripheral surface below the platen roller 26 is disposed slightly above the lower outer circumferences of the other two main rollers 24 and 25.

A guide member for the recording paper 14 is provided at the rear of the platen roller 26.
35 is arranged along the inclined surface as shown in FIGS. 2 and 3, and is fixed to both side plates 22 and 23. The recording paper 14 is inserted from above in the direction of the arrow, and is smoothly carried in in the tangential direction between the platen roller 26 and the main roller 25. The recording paper 14 is curved in a U shape along the platen roller 26 and the transport guide 26a, and the rollers 24, 26 are provided. It is carried upwards at. At this time, the recording paper passes along the surface of the elastic member 29a on the flat platen 29, passes through the gap with the recording head 52, is stopped at the position shown in the figure, and recording is performed as described later.

Further, the driven rollers 27 and 28 are arranged below the main rollers 24 and 25 while maintaining a pressure contact state necessary for conveying the paper in a state where the driven rollers 27 and 28 are maintained in a parallel relationship, and the document 13 is shown in FIG. As described above, the main rollers 24 and 25 and the driven rollers 27 and 28, which are the transporting means, are sandwiched and transported substantially horizontally. All the roller axes described so far have a parallel relationship and are rotated by the sub-scanning motor 30. A flat platen parallel to the platen roller is provided near the platen roller 26.
29 and the elastic rubber member 29a having a flat surface are integrally formed on both side plates 22, 2
Backed by 3.

Further, the driven rollers 27, 28 that are in contact with the main rollers 24, 25
A document upper guide plate 37 and a document lower guide plate 36 that form a sheet medium conveying path for guiding the document 13 along the vicinity of the contact surface of the document are installed in a substantially horizontal state, and the document 13 is placed between these guide plates 36, 37. The recording paper 14 is guided in the opposite direction. Recording paper guide member
Since the lower part of 35 forms a notched bent part 35a partially, the document 13 guided by the upper and lower guide plates 36, 37 is
It is nipped by rollers 24, 27 and 25, 28 and guided along this bent portion 35a, and is stocked on a tray 38 as shown by a dotted line in FIG.

In this manner, the original document horizontally conveyed for reading is given a spring restoring action in combination with the inclined discharge passage to achieve reliable discharge with a simple structure. In this case, the document 13 can be guided to the rear side instead of being discharged to the upper part.

The upper guide plate 37 is further provided with a weak spring agent 37a that does not obstruct the entrance of the document in order to guide the document to the reading unit and the tangents of the rollers 24 and 27 without floating.

Also, the document 13 should be placed between the tip of the lower guide 36 and the rollers 24, 27.
The sensor 60 for detecting the presence or absence of the recording paper guide member 35
A sensor 61 for detecting the presence or absence of the recording paper 14 is provided in the lower part of the. These sensors are realized, for example, by mechanical sensors such as microswitches or optical sensors such as photointerrupters.

The document 13 is inserted into the passage formed by the upper guide plate 37 and the lower guide plate 36 until it hits between the main roller 24 and the driven roller 27. Since the document presence / absence sensor 60 is arranged immediately in front of the rollers 24, 27, the insertion of the correct document can be detected. Further, as will be described later, the correct insertion of the recording paper 14 is detected by the sensor 61 inserted from the recording paper insertion port 15 so as to be in the direction opposite to the conveying direction of the original 12 in order to record the original in the normal position. In this case, it can be understood that the main roller 24 serves not only for positioning the front end of the document when inserting the document but also for feeding the document and the recording paper. In addition, FIG.
Reference numeral 14a in FIG. 3 denotes a battery, which can be supplied with electric power by operating the power supply 11c.

Description of Reading Unit and Recording Unit Next, the reading unit and the recording unit will be described.

As shown in FIGS. 4 and 5, rails 40 and 41 are attached between the side plates 22 and 23.
A carriage 42 is guided in parallel with the platen roller 26 by a main scanning motor 65 via a belt 65a so as to be capable of reciprocating in the main scanning direction. In this carriage 42,
A reading unit 43, which is a head member that reads information on the original 13, and a recording unit 44 that has a recording head 52, which is a head member that records information on the recording paper 14, are arranged adjacent to each other.

The reading unit 43 includes a document illumination light source 44 ', a focusing optical lens 45, a reading line sensor 46, and a photoelectric conversion circuit 47.
A of the original 13 having information upward,
The area a '(FIG. 3) can be scanned by main scanning and read at a constant density, and photoelectric conversion can be performed to send image information to the recording section. The reading line sensor 46 includes a focusing light guiding lens 45.
Although it is composed of (commonly called SELFOC) and the same-time contact sensor 46, it may be composed of a CCD 71 or the like which detects a reduced image formed by using a cylindrical lens as shown in FIG.

In the example shown in FIG. 7, the signal read by the CCD 71 is driven by the driver 72, read sequentially, amplified by the amplifier circuit 73, amplified by the A / D converter circuit 74, and read as a digital signal. An automatic adjustment circuit 75 is connected to the amplifier circuit to automatically adjust the gain.

Further, the recording unit 44 has a recording head 52 mounted on a holding member 51 that can swing on a carriage 42 at a fulcrum 50.
The recording head 52 has a plurality of heating elements arranged in a line in the sub-scanning direction. Reference numeral 53 is a cassette containing a thermal transfer ribbon 54, and the ribbon 54 having an ink layer passes over the element surface of the recording head 52 and its end is wound around another winding bobbin in the same cassette.

The signal read by the reading unit 43 is the fifth signal.
RA via signal cable 70 as shown in FIG. 6 and FIG.
The data is input to an M (random access memory) 80 and processed under the control of a CPU (central processing unit) 81. Similarly, a signal from the document presence / absence sensor 60 is input to the CPU via a signal cable 82, and the main and sub-scanning motors (both step motors) 30 and 65 are controlled via the cable. Similarly, the CPU 81 is connected to the keyboard 11, the character generator 84, the ROM (read only memory) 85, and the display unit 16 via the signal cable 83. The recording unit 44 is connected to the character generator 84 and the CPU 81 via signal cables 83 and 86. These electronic circuits are arranged on a circuit board 90 provided in the lower part of the device.

In the case of this embodiment, the reading unit 43 and the recording unit 44 are arranged so as to be offset from each other on the carriage.
As shown in FIGS. 6 and 6, the recording head 52 is located on the right side, and the reading surface of the reading unit is located on the left side. Therefore, as shown in FIG. The amount S is shifted in the main scanning direction. This makes it possible to read and record at the same time.

Description of Typewriter Function Next, the operation of the typewriter function of the recording apparatus of the present invention configured as described above will be described.

First, as shown in FIG. 3, the recording paper 14 is inserted between the platen roller 26 and the main roller 25, which are the first transport body, from the recording paper insertion opening 15 at the upper rear portion of the apparatus, and the rotary knob (not shown) is used. When the roller is rotated in the direction of the arrow, the recording paper advances in a U-turn shape in the path space formed by the platen roller 26 and the conveyance guide 26a, and moves forward between the platen roller 26 and the main roller 24 to extend forward. The sheet is guided by the member, passes through the space between the recording head 52 and the flat platen 29, and is discharged to the outside of the apparatus.

In order to make it easy to set the leading edge of the paper slightly above the recording head 52, an index (not shown) is provided on the apparatus upper cover or the like for alignment. If it goes too far, you can correct it by turning the rotary knob back. This operation is exactly the same as the work normally performed by the user with an electronic typewriter or the like. In this case all rollers 24-28
Are contacted, pressed or geared, respectively, and all are rotated at the same time and without slipping.

In this way, by rotating the knob, the leading edge of the recording paper 14 is moved according to the rotation angle of the platen roller 26 and stopped at a desired position. At the time of this operation, since the original paper has not been inserted yet, the rollers 27, 28 for the purpose of carrying in and ejecting the original are simply idling during the forward and reverse rotations. A sensor 61 provided below the guide member 35 for detecting the presence / absence of a recording sheet prevents the recording operation when the sheet is not inserted and prevents the print stain on the elastic member 29a.

When the typewriter function is enabled, the operation mode is as shown in FIG. 8, and the character keys 11a on the keyboard 11 are used.
The user can perform the input work in accordance with the sentence structure by operating in a desired order by finger-picking selection, and call up and display it on the liquid crystal display unit 16 as a confirmation before recording to confirm whether or not there is an operation error during the input work. In addition, the input characters are correspondingly generated from the character generator 84, and are respectively recorded in the recording unit 44 or
Sent to RAM80.

The text composition corresponds to the recording density of the recording head 52 and is determined by the apparatus specifications, and differs depending on the recording character quality such as vertical and horizontal 16 dots × 16, 24 × 24, or 32 × 32 dots composition. A plurality of recording heads 52 are vertically arranged in a row at a constant pitch so that the recording can be performed by the sub-scanning motor 30 in the sub-scanning direction (the traveling direction of the recording paper) at a predetermined resolution. Recording head
The number of elements of 52 is set to be equal to or more than the number corresponding to the quality of recorded characters described above.

After correction is made after confirming the above-mentioned work mistake, the display character is recorded on the recording paper 14 by the recording head 52 by the operation of the print input key. In this case, it goes without saying that the data can be directly recorded on the recording paper 14 in response to a key input without performing an editing operation.

At the time of recording, it is necessary to scan the recording head 52 parallel to the recording paper surface in the row direction, and the recording unit 44 having the recording head 52 mounted on the rails 40 and 41 satisfying the condition of being parallel to the platen roller 26 surface. Make a round trip.

This scanning is performed by using a step motor as the main scanning motor 65 operated by the CPU 81 which operates in synchronization with the clock signal. The carriage 42 equipped with the recording unit 44 decelerates the gear as needed according to the rotation angle of the step motor, and the timing belt is wound around the pulley.
It is reciprocally scanned via 65a or the like.

The reciprocal scanning of the recording unit 44 is set to a speed commensurate with the recording speed of the apparatus.For example, when thermal transfer printing recording is performed under the structure of 24 × 24 dots per character, 20 to 40 characters can be scanned per second. , The characters are stepwise moved from left to right in the line in word order with the home position near the left edge of the normal recording paper. For example, when recording 24 x 24 constituent characters, a recording head with a number of 24 dots or more in a vertical line
52 records one character through 24 step movements.

When there are more characters in one line, recording is performed up to the right end, and then the recording head 52 is returned to its original home position by the reversing movement of the main scanning motor 65.
By utilizing this return operation time, a pulse is applied to the sub-scanning motor 30 as a preparation for recording the next row.
The motor 30 has a specified number of steps P ₁ corresponding to this number of pulses.
The recording paper 14 is rotated forward (see FIG. 9 (A)), and the recording paper 14 is stopped forward by the rollers 24 to 26 to which the drive is transmitted. The distance to move forward is the amount of pitch between lines and is defined by the size of the character.

Character generator with a matrix structure
From 84, the on-row recording signals corresponding to the serial recording described so far are sequentially sent to the recording head 52, the selected characters and the like are recorded on the recording paper 14, and the above operation is repeated to complete the type recording. After that, the recording paper is discharged to the outside of the apparatus and the series of operations is completed.

The typewriter function described above is not limited to the electronic typewriter and can be applied to a keyboard type word processor. The recording by the recording head 52 is the same as that described in the embodiment of the electronic typewriter, and the selection of characters by the control of the CPU 81, the editing, the drive control of the recording head 52, the transmission of the signal to the recording head 52, the main, the sub By controlling the scanning motors 30, 65, etc., a recording operation similar to that of an electronic typewriter is performed. This state is shown in FIG. 11 as a power-on step S1 and an electronic typewriter operation step S2.

Description of Copy Function Next, the copy function, that is, the document reading / recording operation will be described.

First, just as in the case of the typewriter function, the leading end of the recording paper 14 is set to the designated position where the recording head 52 has passed by the rotary knob, and the document 13 is set as shown in step S4. In this case, the document 13 is read from the document insertion port 12 below the keyboard 11 along the guide plates 36 and 37 with the character information surface facing upward, and the readable area of the reading optical system (the carriage 42 of the carriage 42 of the document 13 is conveyed). The scanning unit manually advances the scanning unit to a processing unit where the reading process is performed by the reading unit 43), and the insertion is stopped until the main roller 24 and the driven roller 27 come into contact with each other. This position is detected by the document presence / absence detection sensor 60. The distance from the one end a '(FIG. 3) of the optical reading lengths a to a'to be read when the document is inserted to the leading edge of the inserted document 13 is set from the leading edge of the recording paper 14 to the recording head. It is preferable that the distance to the dot start point of 52 is approximately equal.

In this way, when the sensor 60 detects the insertion of the document 13, the circuit with the document is switched to, the reading can be started, and the recording unit 44 is automatically switched to the copy mode as shown in FIG. The state is as shown.

Then, as shown in step S3 of FIG. 11, the copy key 11b (FIG. 10) of the keyboard is operated to enter the copy mode. When the operation is started, the light source for document illumination 44 'is turned on, and the CP
The reading operation is started under the control of U81, and the reading optical system of the reading unit 43 is started to move stepwise in the main scanning direction by driving the main scanning motor 65 (step S
Five). The document 13 is illuminated by the light source 44, the reflected light is imaged on the line sensor 46 through the lens 45, and the reading operation is started (step S6). Accumulated line sensor 46
The analog information from is read out pixel by pixel in synchronism with the step feed, and as shown in FIG.
The signal is amplified by the amplifier circuit 73 via the, and converted into a digital signal by the A / D converter circuit 74 to photoelectrically convert the image information of the subject. At this time, if necessary, a memory such as a line buffer may be prepared and stored for image processing.

The operation control by the CPU 81 is performed by the program input to the fixed memory (ROM) 85, the read signal is sent to the recording unit 44, and the recording is performed at the same resolution as in the typewriter function in synchronization with the step feed ( Step S7). In this case, the illumination light source 44 includes a plurality of light intensity LEDs,
It can be read at a relatively high speed if it is installed in a row near the two-dimensional reading document and configured with a wide-angle lens with a F number of 2 or more, a short-focus lens, or a bright multi-lens lens with a small Tc value of SELFOC. it can. In order to output by the recording head 52 almost simultaneously after reading, it is necessary to perform reading and recording synchronously, and it is preferable to improve the recording speed. Further, the number of pixels of the reading line sensor 46 is at least equal to or more than the number of recording heads of the recording head 52. This is because the image signal from the subject read by a large number of sensor bits has a higher reading resolution, and it is finer and less missing to reduce the number of dots in the recording head by ANDing or ORing this signal. This is because a high quality copy can be obtained.

The original feed amount 13 and the recording paper 14 which are intermittently fed in the sub-scanning direction when operating in the copy function mode P ₂
Is determined by the total length (1) of the number of elements of the recording head 52 as shown in FIG. 9 (B), and cannot exceed it. This is because the image information on the subject is not limited to the characters in the line direction, and when considering a continuous image such as a figure, it is necessary that there be no overwriting and no recording omission, and the paper feed amount in the sub-scanning direction is as shown in FIG. This is because the line pitch P ₁ in the typewriter function mode is different as shown in FIG.
Therefore, when the copy key 11b is pressed to switch to the copy function mode, the CPU 81 automatically converts the pulse number of the sub-scanning motor 30 from P ₁ to P ₂ . As described above, in the copy function mode, the signal read by reciprocal scanning (main scanning) is immediately sent to the recording head 52, recording is performed almost at the same time, and the original 13 and the recording paper 14 are intermittently fed at the pitch of P ₂ and again. Reading and recording are performed by the above-described main scanning, and this operation is sequentially repeated in the longitudinal traveling direction of the document 13 to perform recording (steps S7 and S8). It should be noted that the originals and the recording paper are conveyed in the copying function in opposite directions in the sub-scanning direction because the originals are read and recorded at the same time.

When the trailing edge of the document sheet is detected by the sensor 60 (step S9), the main scanning of the document is completed, and the optical system and the recording head 52
Returns to the home position and the original 13 and recording paper
Sub scanning motor 30 until 14 is free from the last roller
Is driven to discharge the document 13 and complete the entire operation (step S10).

Thus, the sensor 60 is used to obtain signals for starting and ending the copying operation.

As described above, after the document is ejected in step S10,
The process automatically returns to step S2 to return to the control of the typewriter function. This means a return to the typewriter function which is normally used frequently.

In the present embodiment, the main roller 24 has a function of conveying the document 13 and a function of conveying the recording paper 14, and the platen roller 26, the driven roller 27, the main roller 25 and the driven roller which cooperate with the main roller 24. 28 rotates integrally.
In this case, the rollers 24, 26, 27 are not merely in the pressure contact structure, but as shown in FIG. 6 (B), the gears 24a, 26a,
If they are connected to each other via 27a, no slip occurs and the feed accuracy in the sub-scanning direction can be significantly improved. Therefore, there is almost no error in the amount of advance P ₂ between the original and the recording paper (FIG. 9 (B)), and the quality of the recorded image can be improved. That is, as shown in FIG. 6 (B), the drive system is such that the original and the recording paper are fed integrally by the outer periphery of the common roller 24 without slipping, and the separated roller pairs are synchronized. There is no backlash or the like that occurs in gear coupling, etc., compared with the one that is sent by sending, and high-accuracy synchronous feed is possible. Further, it is possible to perform high-quality image recording without causing skew in the process of conveying the document and the recording paper and causing skew.

Further, the driven roller 28 may not only be brought into pressure contact with the main roller 25, but may be connected via a gear or the like to further ensure the integral rotation.

Further, in the present invention, since the pair of the main roller and the driven roller are provided on both sides of the platen roller 26, the document can be conveyed smoothly, and the platen roller can be arranged between the pair of rollers. The device can be made thin. In this case, both rollers 24 and 27 on the side of inserting the original are arranged to hit or position the original at the time of inserting the original, as described above, and the function of the conveying roller is improved.

Further, as shown in FIG. 12, the notch 36 is formed in the lower guide plate 36.
Alternatively, weak elastic members 36b, 36b may be attached to the lower guide plate 36 so as to face them, so that the driven rollers 27, 28 function. In this case, the entire device can be made thinner.

Other Embodiment of Document Insertion Section FIGS. 13 to 18 show another embodiment relating to the keyboard 11 and the document insertion structure. Typewriters with a long history have been studied ergonomically, and they are tilted toward the front side so that they can be easily used, and are easy to operate on the table, and the front end side is made ultra-thin. There are many.
In addition, the electronic typewriter, word processor, etc., can be used for the display unit 16 in order to confirm, arrange, and edit the characters after key operation.
Is placed behind the keyboard 11 at a position where it is easy to see.

As described above, in the present invention, the document inserting section is the keyboard.
An original guide passage composed of an upper guide plate 37 and a lower guide plate 36 is formed immediately below the substrate unit 92 of 11.

When inserting the manuscript paper, as shown in Figs. 13 and 14,
The operability is further improved if the guide base 91 is taken out forward to serve as an auxiliary base only during the reading operation of the document folded on the lower part of the base. As shown in FIG. 14, the guide base 91 rotates around a shaft 91b when it is unfolded to serve as an auxiliary base for inserting a document. When not in use, the guide base 91 is as shown in FIG. The projection 91a is fitted into the recess 20a of the base 20 and folded.

Further, as shown in FIG. 15, guide walls 91c are integrally formed on both sides of the guide base 91 to prevent the document 13 from skewing. The lower guide plate 36 is connected to the guide wall 91c.
If guide walls 36a are formed on both sides of the
It is possible to improve the accuracy of entry in the sub-scanning direction.

Further, the document insertion opening 12 does not necessarily have to be provided at the front end portion, but may be provided at the bottom portion as shown in FIG. In this case, the base 20 of the apparatus terminates below the center of the keyboard 11 and serves as the document insertion opening 12 '. The document is inserted by guiding the front end from the front, side or bottom of the keyboard 11 and inserting it into the document insertion port 12 '.

Also, in order to make it easier to insert the document 13,
As shown in FIGS. 18A and 18B, a hinge portion may be formed between the main body exterior 21 and the keyboard 11 with the fulcrum 11d of the keyboard 11 as a center so that the hinge portion can be opened upward by manual operation. By arbitrarily setting the opening angle, the operator can view the keyboard lower region over a wide range. Below the keyboard, a document guide member 95 that constitutes a document (sheet medium) placing section corresponding to the document size of the size to be read is installed to meet the condition perpendicular to the movement of the reading optical system in the main scanning direction. A guide wall 95a forming a guide side surface for guiding the side edge of the document is formed so as to substantially coincide with both edges of the document. Further, in order to correctly guide the document to the reading unit (the information processing unit for reading the image information of the document as described above) in the rear of the apparatus, the tip of the upper guide member 37 is folded back upward and installed. With this, it is possible to easily guide over the long dimension at both ends in the longitudinal direction of the document, and then it becomes easy to pass through the reading area and insert the leading end of the document into the carry-in roller portion that is the document (sheet medium) conveying means. In addition to facilitating the attachment of the original document by such a configuration, even a small-sized original document can be reliably conveyed and can be read. It should be noted that the keyboard 11 is closed and locked by the locking means 96 realized by a magnet or a hook when the document insertion is completed or when the keyboard is used.
