Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention is a Japanese text printing device, particularly a Japanese text printing device, which has at least twice as many types of type as a conventional Japanese typewriter in a ready-to-use state, and which is also fast. Concerning things that can be printed.

(b) Prior art A conventional Japanese typewriter/koi, for example, has 1,850 regular kanji, 2 hiragana, 2 jirugana, 351 numbers, codes, etc.
There is a dial with a total of 2,201 characters, with the most frequently used 1st class characters (271 characters) in the center, and 2nd and 3rd class characters in left and right exposed letters. A case containing 858 1 ko 1 spare characters and 2297 stored characters is prepared. When typing, the operator guides the dial from side to side and the type keys from front to back, left and right, and in the case of a type direct view type, looks directly at the desired type, aims at it, and presses the key. Through this bushing operation, the desired type gripped within the square frame at the tip of the type bar is pulled up together with the tights; rotated about 90 degrees, and printed on the paper wrapped around the platen.
After printing, the type bar returns and returns the type to its original location.

In this way, it took time to pick up the desired type while moving the dial 6 and the type keys, and although there is a record that the typing speed was 735 characters in 10 minutes, the standard printing speed was 1st grade. In case, 100
As can be seen from the fairly low regulation of 500 characters per minute, it was considered extremely difficult to increase the printing speed.

Recently, word processors have been able to print Japanese text mixed with kanji at several times the print speed of Japanese text, but because the print is formed using the dot method, the size of two characters is commonly used in official documents. When it comes to size 4, there is a noticeable difference in the finish compared to conventional type printing, which makes it look inferior.
The printing on some products may fade due to aging.
Furthermore, because it is not possible to print the unique kanji characters used in people's names and place names in family registers, for example, the traditional Japanese type is still often used when creating official documents.

Under these circumstances, the Japanese typesetting industry is trying to increase the number of characters it possesses by using the same typeface as before, making it possible to easily pick up the desired type without any skill, and improving the printing speed at least as much as the conventional type. There is a need for the development of a Japanese printing device that is about 10 times more powerful, equipped with a large number of typewriters, and eliminates the inconveniences faced by those who had to deal with it exclusively during sea entry operations.

(C) Purpose This invention was made in response to the above-mentioned demands of the Japanese typing industry. By simply specifying the desired character with a stylus pen, etc., the conventional type pickup operation can be performed, and all other operations are performed automatically.

(E) Embodiments Three embodiments of the apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing the configuration of the main parts of this individual packaging device;
FIG. 2 is a partial plan view thereof.

This device includes a type feeding device (2) that transports and positions desired type to a printing position opposite to the platen, and a paper feeding device (2) that transports and positions a roll of type paper to the printing position.

The type striking device 0 and 9 are connected to an input device not shown in the figure. It consists of a control device.

The type supply device (2) is constructed as shown in FIG. That is, as shown in FIG. 4, on the surface of an endless belt (1) made of plastic material.

In the example of a certain pinch t, it is about June, accurate) This is 2π1
m), a certain number of printed characters (2), for example 200, are formed integrally with the belt (1).

This endless belt (11 is the flat case shown in Figure 3 (the front side plate has been removed) The driving pulley (5) and the guide pulley +61.1703 are rotatably engaged with each other, and the driving pulley (5) is connected to the support leg (9) on the base plate (8) of the housing (4).
The belt is driven by a flange-type pulse motor αa+, which has a fixed flange-type pulse motor αa+. And printing position [F]
It is necessary to transport and position the desired type (2) without clouding.

Endless belt (11 has a typeface (11) with tooth-like protrusions I with a triangular cross-section on the back surface extending over the entire width as shown in Figure 1.
2) Match the center wire numbers in the width direction.

This belt (
1) The hook is passed to the driving boo +7151. The guide pulleys (61, (71) both have tooth grooves carved at the same pitch t on their respective outer peripheries into which the protrusion αJ fits,
The belt (1) runs without slipping and moves by a length proportional to the rotation angle of the drive pulley (5), thereby making it possible to accurately move the type (2). This is also required for the belt drive by the pulse motor (to) of the drive pulley (5), so a miniature timing belt is used for this belt, and the output shaft of the pulse motor α The driving pulley (2) and the driven pulley (2) to be attached are the pulleys for the timing belt, respectively.

It goes without saying that the guide boos 7 (6) and 171 are all supported on shafts so that they can rotate freely, but the drive boob 5) and the driven boob 9 (134) are equipped with miniature ball bearings. It is.

The housing (4) is designed to rotate smoothly on a fixed spindle. The belt 111, which is made to be moderately hard because it is integrated with the type (2), has grooves (3) between the type (2).
) to supplement flexibility. A casing (4) in which one such endless belt (1) is housed,
As shown in FIG. 2, multiple rows are arranged at a pitch T on the base plate (8).

In this embodiment, for example, 19 columns each are designated as printing areas (Pt).
Treated as one group with G position.

As shown in the schematic plan view number in FIG. 5, three groups are provided from the left side to the right side: an L group, a 2M group, and an R group.

Therefore, the total number of endless belts (1) is 57.
Since the book is made up of 200 types (21) per belt (1) and is formed as described above, this type feeder is equipped with 11,400 types (2). In conventional Japanese typewriters, 1.
For example, 1850 kanji for regular use, 9 hiragana, 9 igana, numbers,
351 characters such as codes, 2201 characters in total, 858 spare characters stored in the case below the surface of the board, 229 characters
Even if you add 7 characters, the total number of printed characters you have is.

The unique feature of this device is that it has more than twice the number of printed characters (2), which is significantly more than 5356 characters, and is ready for immediate use.

In this way, for example, 19 rows of endless belts (1) are arranged in each group, so that each belt (1) is driven by a flange-type pulse motor (1 (I is a motor as shown in FIG. 2). To avoid mutual interference, support legs (
The fixing positions on the base plate (8) via 9) are shifted in units of 5 rows or 4 rows, respectively. In order to avoid interference with the pulse motor αG disposed close to each other, the rectangular opening 9 is connected to the stage loading device 0.
In addition to the opening side provided to avoid interference with the printing position 0, the printing position 0 side is completely wide open.

As mentioned above, since it is necessary to position only one of the M and R groups in the printing area (pt), the base plate (8) on which the 57 casings (4) are arranged is 5. Figures 6 and 6: As shown, the traverse must be made to the left by the width W of the first group, or to the right (not shown).

For this purpose, one board (8) is placed in the left and right direction relative to the base Oh.

That is, it is slidably engaged in a direction perpendicular to the main running direction of the endless belt (1).

As part of this mechanism, one plate (8) has a guide bracket ■
are fixed to the lower surfaces of the ends in the radial direction, and these guide brackets are parallel to each other, and both ends are fixed to the brackets (181I) fixed to the base (171).
These are slidably and snugly fitted into a pair of horizontal guide shafts α bags, which are each supported. Furthermore, in order to retraverse the base plate (8) as described above, a double-acting air cylinder @ having an operating rod with an effective stroke of 2W on each side is located at an intermediate position between the pair of guide shafts a9.
When the piston (to) is in the neutral position, the descendants are fixed to the base (171, and left and right) so that the center cross section of the piston matches the center line of group M in FIG. A folded auxiliary rod (2) having a length equal to 1 of the width W of each group is connected to each of the protruding operating rods (2), and the end of this auxiliary rod (2) is connected to the auxiliary rod (2).

The base plate (8) is connected at a position corresponding to the left end in the L group and the right end in the R group. Therefore, if pressurized air is supplied to the air cylinder (2) in FIG. 5 via an electromagnetic directional control valve (not shown) so that the piston (2) moves, for example, to the left.

As shown in Figure 6, each group of L, M, and R is 1
The group is shifted to the left by the width W of the group.

The arrangement is such that the R group is positioned at the center position, that is, the above-mentioned printing area (pt). Although it is located on the right side of Figure 2, it has been included for convenience of illustration.

〉 If air is supplied to the descendant air cylinder @1 so that the piston moves to the right in the opposite direction to the above, then L, M
, R groups as a whole are shifted to the right by the amount W described above, and the L group is positioned in the print area (Pt). In order to maintain the base plate (8) in the position shown in FIG. 5, the piston (2) must be stopped at the neutral position. Although not shown as a means for this, a coil spring may be attached to the guide shaft a (g) and rubbed so as to apply a suppressing force to the two plates (8).

Next, the configuration of the paper supply device (2) will be explained. The paper supply device ■ is installed close to the front of the type striking device, and is connected to the platen ■ which is fixed to the carriage (c) with the printing position [F] and center height aligned with the carriage (c). A paper winding reel and a paper feeding reel (2) are provided on the upper and outer sides of (2) and (2), respectively, and the paper fed out from this feeding reel (2) is attached to the reel shaft. A guideless take-out mechanism (2) that guides the rolled paper through the platen ■ and onto the take-up reel ■.

(to), clll, (to), and a screw feed mechanism (C161) that moves the carriage (c) laterally. Paper (S) fed out from the feeding reel (support)
The carriage aSS Knead [frame body attached via a hinge with a recoil spring] is a guide roll (
The sheet is guided upward through the platen (A), and is passed through a delivery roller consisting of a drive roll 31J and a presser roll (A).

It is adapted to be taken up on a take-up reel @. And for driving the take-up reel (5).

A slip joint is interposed between it and the gear motor that drives it, and the paper (S) is sent out from the drive roll (3υ), which is intermittently driven by the pulse motor, and the presser roll @, which is friction-driven via the paper (■). Therefore, regardless of the winding diameter of the winding fin, the paper (2) is rolled from the feed roller in accordance with the rotation angle of the drive pulse motor accurately. An electromagnetic clutch is interposed between the pulse motor and the drive roll (9).
If you want to pass the paper through the vQ3, rotate the frame described above counterclockwise at the hinge part, pull the small roll 4 away from its contact surface, and move the end of the paper (2) onto the guide roll ( ), the frame body may be elastically returned to its original position after being passed through the platen (2).

The carriage □□□ is the type feeding device Wt explained earlier.
Place the paper (■
A feeding nut portion (toward) is slidably engaged in a direction orthogonal to the main feeding direction of the carriage (2) and is fixed to the center of the lower surface of the carriage (2).

A feed screw shaft 3H, which is rotatably supported by bearings (2) to which both ends of the base plate (2) are fixed, is screwed together. A feed screw shaft C1 [ilp extension shaft portion extending outward from one of the bearings (2) is connected to an output shaft of a pulse motor for carriage traverse via a shaft coupling.

The base plate is attached to the base so that it can slide a certain amount in a direction perpendicular to the feeding direction of the carriage (2), that is, in the same direction forward and backward.

As mentioned above, when transferring the paper ■ from the feed reel (2) to the take-up reel ■ and the hook.

It can be pushed forward if necessary.

In the type striking device 0, the printing hammer (to) is at the printing position [F
] The hammer head (
), and the rear end of this printing hammer (to) is
It is connected to the front end of the operating rod of the direct-acting solenoid built into the casing (A) via a link that is pivotally supported by the casing (G) at a position above the middle.
When the solenoid coil is energized, the actuating rod is suddenly retracted against the elastic force of the coil spring attached to it, and its movement is amplified by the printing hammer through the link. The printing hammer (to) is suddenly pushed out from the hammer (from 391).
The pushed-out printing hammer hits the desired type (2), which is positioned at the printing position [F], from the back side of the endless belt (1), and the ink ribbon (
A sheet of paper (S) is twisted against a platen (A) with a paper (not shown) in between. Although the figure number is not shown, a recess is formed at the tip of the S mark of the printing hammer in a shape that is almost conjugate with the protrusion αV' on the back side of the endless belt (1) shown in Fig. 4. There is.

The casing (40) is attached to the base plate (41J) attached to the base a71 of the type feeder, and the endless belt (1)
The guide rails are slidably engaged with guide rods arranged parallel to each other and perpendicular to the main running direction of the motor. A feed nut portion (c) is fixed to the lower surface of the countersunk casing +401 &ko, and this feed nut portion (c) is screwed onto the feed screw shaft portion. The feed screw shaft was then fixed to the base. It is supported by a pair of bearings for simultaneous rotation.

As shown in Fig. 2, the shaft section extending outward from the left side of the bearing is connected to an M group of endless belts (1) connected to a pulse motor (individually) through gears that mesh with each other. It is designed to traverse within the printing area (pt).

Regarding input devices and control devices.

This will be explained as appropriate in the explanation of the operation of this device, which will be explained next.

It is assumed that group M of the type feeding device (2) shown in FIG. This M group has a total of 380 printed characters (2)
It is 0 characters. As mentioned above, in a conventional Japanese style writer, there are 3059 characters that can be used at all times, including the spare stored in the case below the dial, so in this device, the printing area (pt) This means that the M group alone has a greater number of characters than the conventional one.

By the way, among the 19 endless belts (1) in Group M, the 200 printed characters on the belt (1) in the middle position (the second one shows the most frequently used characters and codes).

The traversal of the printing area (pt) + 7 of the active 7 devices 0 of each belt (1) sequentially arranged on the left and right of the belt (1) is minimized so that the types can be uniformly printed.

Furthermore, each belt (1) is equipped with 200 printed characters, and these printed characters are divided into printed characters located at printing position 0. The printed characters (2) are located at 9 from positive 1 to calm 100, and the endless belt (1) is run in the counterclockwise direction indicated by the arrow. The controller is driven by a pulse motor QQ as shown in FIG. This pulse motor αα is driven by this. Therefore, the type (2) of Arashi 1 is now placed at the printing position [F], and the type (2) of the pole 5 is placed at the printing position [F].
] When positioning, use the pulse motor α1.
Move the endless belt (1) counterclockwise by 4 pinches. If you want to position the 1h150 letters (2) in the same way, you need to move the pulse motor (11f endless belt (1)) clockwise by 51 pifts.Since it is done like this,
The traveling distance of the endless belt (1) required for positioning the printed characters is minimized, and the time required for positioning the desired printed characters (2) is shortened. When printing is completed, the printed characters (2) are returned to their original positions each time.

be thrown away.

Also, the arrangement of the typeface (2) and the border t in this example are about 6 mm because it depends on the size of the typeface (2).
For example, the reason why it is set to 2π pitch is to increase the number of operating pulses of the pulse motor a corresponding to this one pitch movement by an integer number.

Feed out the paper from the feeding reel (support), pass through the small roll ■, guide roll ■, and scrape the edges ■.
Set it by winding it around the take-up reel ■ between the drive roll 3υ and the presser roll (to). In this case, as mentioned above, by pushing the carriage (2) forward by a slight amount,
When passing the small roll device, it is easier to set it by rotating the holding frame counterclockwise. In the case of manual rapid forwarding, the electromagnetic clutch on the driving roll surface is released and the knob at the left end is turned by hand.

In the case of horizontal typing, the line feed, that is, the vertical feed, is done by the drive roll C11l.The pulse motor can be operated by a predetermined number of pulses, and the so-called shift, such as 9-character spacing, is required. For this purpose, the pulse motors of the feed screw shafts of the carriages may be actuated by a predetermined number of pulses.

Until now, we have used the term "printing position" without providing a strict definition, but 1. The printing position [F] that moves through this device is not fixed. That is, the printing position [F] is the constant coordinate value of this device, the height direction, that is, the z-axis, and the horizontal direction that changes within the printing area (Pt), that is, the
This is because it is defined by the variable coordinate values of the axes.

However, the characters (2
) when printing is done.

No need to do anything.

However, the belt (1) row of the M group mentioned above is named M1 to Mml from left to right, and the desired type (2)
is not in the middle position bell)fi+, that is, M, and for example, if there is a belt Myt on the left side of it, then in this bell)My, the printing position (P)f is the desired character (2) as described above. When you position the
It is necessary to drive the feed screw shaft (43) by a pulse motor (
The number of operating pulses is determined by the thread pitch of the feed screw shaft (c),
The ratio of the teeth of the gears that interlock with each other, the number of pulses per revolution of the output shaft of the trowel, and the unit and edge T.
Since the corresponding number is indexed in advance, the printing position (P') that moves in pulses is tripled, and by shifting the number, the desired type (2) is printed. However, prior to that, the predetermined printing position on the paper 2 must be aligned with the printing position (p') t mentioned above.

Therefore, shift the paper supply device■.
The number of actuation pulses for shifting is input in an amount equivalent to one traverse that is an integral multiple of the arrangement pitch T of the endless belt (Pt).

Immediately after the printing operation is completed, the type striking device 0 returns to the original printing position 0. On the other hand, the paper supply device (2) is designed to automatically shift the carriage (251) by a predetermined distance between characters each time one print is completed by the type striking device Ot. In order to perform foggy printing of the type (2) positioned at the printing position (P') on the belt M described above at the predetermined 1 character position t on the paper ■, the carriage (to) continues to advance the characters by ?3T. A shift is performed in the same direction as , and a shift to cancel the above-mentioned residual shift is automatically performed immediately after printing is completed.

By the way, if the desired type character (2) is not in the M group, traverse of the entire type character feeding device (4) by the width W is performed by operating the air cylinder @. For example, when the desired type (2) is in the R group, the center position of the 8th group is shifted by this as shown in FIG. The subsequent operations are as described above.

The operations performed by the type feeding device (the paper feeding device) and the type striking device 0 of this device in a signature manner have been explained above, taking up the case of horizontal writing.

Each of the above-mentioned operations includes the drive pulse motor aα for each of the endless belts (1) (57 rows in the example with multiple rows), the endless belt (1) glue, and which of the M and R groups prints one group. Carriage area (electromagnetic directional control valve of air cylinder, paper feeding device) to position Pt □
A pulse motor that shifts □□, a package smoke for feeding paper ■, a pulse motor that moves the type striking device C) to traverse the printing area (Pt), a solenoid that operates the printing hammer (to), etc. A predetermined number of actuation pulse signals or ON-OFF signals, including directionality, are output from a control device equipped with a microcomputer in accordance with a predetermined sequence via an inter 71 ace connected thereto. If the computer is programmed in advance, the operator can input the letters, numbers, and symbols required for the text to be typed.
An input device consisting of a tablet and a stylus pen in which these human elements are arranged according to the frequency of use, for example, to print the number of characters, the number of characters per line, the number of characters per line, and the number of characters per line. This can be easily done by simply inputting the information to the control device via the .

In addition, the signals input to the input device described above are temporarily recorded on a floppy disk, and the floppy disk is later read by the control device and operated in the same manner as described above. It is also possible to have the FIG. 7 is a block diagram showing a schematic configuration of the input device and control device described above. The figure in the figure is an input device with two characters, codes, etc.

), a microcomputer (CPU) (55), and an interface (56).

Note that (57) is a floppy disk. (2) is the pulse motor 011 and electromagnetic directional control valve of the type feeding device (4), (2) is the pulse motor for shifting the carriage (2) of the paper supply (device), and the pulse motor for sending out the paper (2).

(2) corresponds to the shift pulse motor of the type striking device 0 and the solenoid G for operating the print hammer (to), respectively.

In this Japanese character printing device, a plurality of input devices (A) are prepared, and the auxiliary device operates independently from the printing device as described above, and records each input signal on a respective floppy disk (57). By adding this, it is possible to increase the operating rate of this Japanese character printing device and at the same time further improve the apparent printing speed.

In the above explanation, we took the case of horizontal writing, that is, horizontal writing, as an example, but in the case of vertical writing, the printed characters (2) are formed on the surface of the endless belt (1). In this case, by simply turning the typeface by 90° counterclockwise when viewed from above in FIG. 4 to form the typeface (21), the same operation as in the case of horizontal writing can be typed.

→Effects The Japanese character printing device using this invention has the following effects.

(+) Simply use the stylus to select the desired one from the tablet, which has kanji, non-kanji, symbols, etc. arranged according to the degree of use.

There is no need for the conventional troublesome operation of picking up type, and most of the other operations are performed automatically, so even without much skill, the printing speed can be significantly improved compared to conventional devices. The high-speed printing mentioned above can be easily performed.

(II) By having multiple rows of endless belts with a large number of type characters arranged at a constant pitch, it is possible to compactly accommodate at least twice as many types as conventional devices while being ready for immediate use at all times. 2. Therefore, it is possible to quickly type various documents in Japanese, including official documents such as family registers where unique characters such as names of people and places cannot be omitted, without any trouble.
