Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a tab nQ tty system in word processors, typewriters, telex printers, etc.

PRIOR ART □ Figures 1 to 6 show an example of an apparatus to which the present invention is applied.
In order to explain the printer as WIJ, Fig. 1 shows the flat curved l
1-■ Enlarged cross-sectional view cut at Y1], No. 3
The figure shows the printer in Figure 1 connected to the line 111-11.1 in Figure 2.
FIG. 4 is an enlarged cross-sectional view of the printer in FIG. 1 cut along m IV-IV in FIG. 1 is an enlarged cross-sectional view of the printer shown in FIG. 2, cut along the lines shown in FIG. 2, and FIG. 6 is a block diagram of the control circuit used in the printer shown in FIG. .

Referring to FIG. 1, a static speed printer is shown in its entirety, with a platen 11 mounted on a frame 10, and platen 11 having knobs 12 and 18 for rotating it and the paper wound thereon. It stands out. Carriage 1
4 is arranged to move m,' hp h over rondes 16 and 17 attached to the frame 10. The carriage 14 has a rotating wheel 18 on which a number of type characters are attached.
and a hammer assembly 19, shown in FIG. 2, for striking selected letters of a plurality of letters on a rotating wheel. As shown in most detail in FIG. 5, there is a ribbon carriage 21 having an ink ribbon 22 sandwiched between type 24 and the paper to be printed.

The ink ribbon 22 is advanced by a stamp motor 26 as shown in FIG.

Further referring to FIGS. 1 and 2, the carriage 1 further carries a motor 27 having a shaft 28. As shown in FIGS. A rotary wheel 18 is attached to one end 29- of the shaft 28.

The rotating wheel 18 is made of rubber and includes a central hub part 1Ail with a reinforcing ring 82. The hub part 3 reinforced by the reinforcing ring 32 makes it possible to easily remove the rotary wheel 18 from the end 29 of the shaft 28 and replace it with another rotary wheel, for example with a different type set.

Attached to the other end 83 of the shaft 28 is a transducer 34 which provides a position relative to the rotational position of the shaft 28 and therefore of the rotating wheel 18. converter 3
4 includes a constant disk adjacent to a disk 86 provided for rotation with shaft 28. The electrical interaction between these two disks 35 and 36 generates a positional signal which is used in the servo actuation to control the rotary wheel J8 as described below. Passage, Disc 85
and 36 contain a number of parallel conductors on their surfaces, and one disk is supplied with a high frequency M 4m from an optical beam. This signal is coupled to the other disk in such a way that the position and velocity of the OJ1 shaft 28 and its rotating wheel 18 are detected.

The rotating wheel ■8 shown in Fig. 3 includes spokes 37 of the same shape, and each spoke 3
7 extend from a central hub 88, each spoke carrying a type 24. A typical cross section of the spoke 37 is shown in FIG. The typical thickness in the direction L to the plane of the paper 28 is about 0.076 crfL (0.03 inches), and the width in the direction of rotation of the rotating wheel 18 is about 0.1 Ocrn (0.040 inches). It is. As is clear from the figure, such a cross section provides greater flexibility in the direction of the axis of rotation, that is, perpendicular to the surface to be printed, and relatively greater rigidity in the direction of rotation of the rotating wheel itself. give. This pruning improves the dynamic alignment of printed characters and provides high quality printing. The valley spokes 37 are made of a nylon phase material containing 83% glass. This glass content is believed to maximize the life of wheel J8 and reduce fatigue failure. Additionally, the width and thickness dimensions described above are considered ideal. For example, if the width is about 0.10 cm (0,040 inch) or more, the rigidity will increase, but the weight of the rotating wheel 18 will increase, so the rotating wheel 18 will be It will be more difficult to link quickly.On the other hand, about 0.076C
As for the thickness of TL ('o, o 3o inches), if the thickness were to be greatly reduced from this one side, the tendency of the forces acting on the type to break the spokes would increase. . On the other hand, reduce the thickness to approximately 0.076 cm (0,03
0 inch) or more, fatigue damage will occur for a short period of time.

In any case, in order to obtain good print alignment, the width dimension (j) must not be large enough to obtain excessive stiffness; of course such a cross-sectional shape cannot be obtained by the teachings of the prior art. Since the rotary wheel rotates continuously, it must be flexible in the direction of rotation, that is, in the width direction.However, the rotary wheel 18 controlled by this device is Because it is driven by such a 1g1 transformation, the challenge of the manager is not a problem.

Referring again to FIG. 1, movement of the carriage 14 is provided by a carriage motor 38 mounted on the frame JO. This carriage motor 88 has a shaft 89. A pulley 41 is attached to one end of the shaft 89 and has a plurality of shafts and moves a cable 42 connected to the carriage 14. This connection is formed via pulleys 48, 44, 45 and 46.

A rotating disk 47 is additionally mounted on the other end of the shaft 89 of the carriage motor 88. The rotating disk 47 electrically interacts with the stationary disk 48 to indicate the position of the shaft 29 and the position of the carriage 14. converter 4
7.48 is almost in the opposite direction to the rotating wheel's niyuki 8↓.

To automatically feed paper, a paper merging motor 51 is defined in the frame 10 and drives the platen 11 via a gear train 52. Paper supply motor 5

FIG. 7 shows both the carriage servo device 54 and the rotating wheel servo device 57 of the j1100. Therefore, the motor 6o shown in FIG. 7 serves both the carriage motor 38 and the wheel motor 27.

Referring to FIG. 7 in detail, the motor 6o is shown as driving a printing circuit 61 connected to either a printing circuit wheel or a carriage. The shaft 61 is also coupled to a transducer 62, which may be the stationary disk or rotating disk described above. Typically, each disk contains a number of parallel evaporated gold filaments, each conductor carrying a current in the opposite direction to that of the respective Idib conductor, one disk being connected to an oscillator 63. There is. The relative interlocking of one disk with respect to the other results in an electrical interaction that generates two position signals A/ and G. These position signals A/and blur,
These are modulated waves obtained by modulating a high frequency carrier wave generated by an oscillator 68 with alternating current signals having variable frequencies proportional to the relative interlocking speeds of both disks and constant amplitudes whose phases differ from each other. and 66 for demodulation, and position signals A and B are generated which have the same wave height amplitude and frequency, but whose phases differ from each other. These signals are fed to a velocity output unit 67 to generate a velocity signal 1E", which is obtained from positions 1d A and B which are inverted, differentiated and rectified by a logic unit 67. .The speed signal E is directly supplied to the adder circuit 468.The speed reference signal 1F" is also connected to the adder network 68 via the level control unit 71 by means of a rectifier unit 69, which converts the position signal A and B is generated and supplied to adder circuit #'168.

The level control unit 71 controls the level of the speed reference signal 1F" supplied to the summing network 68 and thus the motor 60.
It consists of a plurality of parallel connected field effect transistors which are adjusted by an external control input to control the speed of the A deviation signal is generated on the line 72 due to the difference between the speed reference signal 1F" and the speed signal
It is clear that the mokro 0 is driven in response. Controlled inverter 74 rotates motor 60 clockwise or counterclockwise in response to the supplied directional input. In order to stop the motor 60 at a predetermined position in order to stop the carriage or printing rotary wheel driven by the motor 60, a control is provided with a position signal i which is inverted from the position signals A and B1. A ring unit 76 is provided. An output line 77 of the control bias unit 76 is connected to an adder circuit #68.

The differential number applied to control logic unit 76 is
Because of this difference, this motor is stopped when it has moved by the corresponding number of units. Therefore, referring to FIG. 6, the carriage-ring unit 56 instructs the carriage to move a certain distance depending on the position where the next character is to be printed, and this distance is determined by inputting the difference number. Ru. As mentioned above, the direction of the interlock is also commanded via the data line, more specifically via the highest order command bit, which is provided to the inverter 74 as the direction input.

Of course, it is obvious that there are other modes in which the direction input is obtained, for example, by inverting the speed reference signal 1F" from the rectifier unit 69. Note that although an example of a printer to which the present invention is applied has been described above, The above printer is described in detail in Japanese Patent Publication No. 56-8888, so please refer to the above publication if necessary.

(For printers such as 7U, there are two methods for displaying tabs: conventionally (well, there is a method of storing tab codes as tab codes, and a method of converting tab-hoods to space codes). There is a method that I remember, but the former is
When outputting to a printer or display, convert the tab code to a space code, or use the printer c
It is necessary to provide a tab cent register and a tab function to two displays, etc., and the latter has the disadvantage that operations such as cursor shift and character delete can only be processed in units of one space.

Purpose The present invention has been made in order to eliminate the drawbacks of the prior art such as "double string", and in particular, to store data in space code to eliminate conversion at the time of output,
The cursor operation after data input is facilitated by providing a composite code character so that the movement of the cursor can be treated as the same as one character.

■, set the composite code attribute 5a=1, increment the horizontal cursor pointer 109, and press the encoder 101 until the output from the tab set position register 108° becomes l.
The side transfer of writing the output (space code) to the data memory 108 is repeated. Data memory 10 at this time
The state of No. 3 is shown in FIG.

one delete input ■, % + rotation for the mouth is activated by the incoming cup dope.

(2) Since the output from the decoder 102 is a de-IJ data, it is set to 56-1, and after decrementing the first half address pointer 104, data is read from the data memory 103 by the read strobe S5.

(2) Set s'y=1 and decrement the horizontal cursor pointer 109.

(2) If the composite code attribute of the output from the data memory 10B is O, the process is terminated, and if the composite code attribute is 1, the processes in (2) and (2) are repeated until it becomes 0.

Effects As is clear from the above explanation, since the data is stored in the space code according to the present invention, there is no need to convert the code at the time of output, and since it has a composite code attribute, the movement of the cursor is It can be treated in the same way as a character, so it is possible to improve operability, and
Since it is easy to interface with an output device that does not have a tab function, there are advantages such as cost reduction.
