Abstract

PURPOSE:To prevent the occurrence of noise with the softening of a ribbon and also the lowering of printing speeds by controlling the holding time of a solenoid according to the ability of operators. CONSTITUTION:The holding time of a solenoid 9 is controlled by manually operating a selector dial D, and the softening action of a ribbon is effectuated according to the ability of operators. The dial D is connected to a volume 11 which is operated by the dial D. Output current is changed by operating the volume 11 and digitally converted through an A/D converter 12. The data are put in a controller 13 which controls a driver 15 backed up by a power source 14. The holding time of the solenoid 9 can thus be freely selected by operators for selection of recording mediums according to the ability of the operators.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a recording apparatus, and particularly to movement of a recording section.

[Prior art]

For example, recording devices such as thermal printers, wire dot printers, word processors, and typewriters are becoming more and more multi-functional and high-performance, and the burden on the operator is becoming lighter, especially with typewriters that are capable of &Iit'J5, etc. , it is now possible to create advanced documents even without specially trained operators.

However, many of the functions are intended only for relatively experienced operators, and some functions are not intended for beginners, making them difficult for beginners to use.

For example, a ribbon lift operation during recording is one of them.

In particular, a typewriter, which is a conventional recording device of this type, will be explained with reference to FIGS. 1 to 3.

Figure 1 explains the external appearance of the typewriter, and a keyboard 1 is located on the upper surface of the typewriter on the front side. Recording is performed on a recording paper 4 wound around a platen 3 by a type wheel 6 provided on a carriage 2 that reciprocates in the horizontal direction.

A type wheel 6 is provided on the platen 3 side of the carriage 2 and is rotationally driven by a motor (not shown).

FIG. 2 is a perspective view of the recording section, and FIG. 3 is a side view. On the front side of the type wheel 6 is the /X mark unit 7.
A hammer 7a is attached to the tip of the hammer unit 7.

Also, a printing ribbon cassette 8 is placed on the carriage 2.
l can be installed.

The printing ribbon cassette 8 covers the left and right arms 8a and 8b, and the printing ribbon pulled out from one arm 8b side is attached to the other arm 8.
The printing ribbon is drawn into the a side and wound into the printing ribbon force set 8. The print ribbon passes between type wheel 6 and platen 3, as shown at 8C in FIG.

On the other hand, the printing ribbon cassette 8 is rotatably supported on the carriage 2 side via a lever 8d, and is locked by a hook 5 in a reloaded state so as not to come off.

Further, a torsion coil spring lO is provided on the lower side of the printing ribbon cassette 8, one end of which is locked to the shaft side, and the other end is in contact with the lower surface of the printing ribbon cassette 8.

Further, a solenoid 9 is provided on the lower surface of the leading end side of the printing ribbon cassette 8, and its rod 9a is in contact with the lower surface of the printing ribbon cassette 8. The rod 9a is lowered when no current is supplied to the solenoid 9, and in this state, the printing ribbon cassette 8
is rotated clockwise in FIG. 3 by the torsion coil spring 10, and the printing ribbon 8C is in a state of being lowered from the printing position.

During printing, when there is an input from the keyboard, the solenoid 9 is energized and the rod 9a projects upward. As a result, the printing ribbon cassette 8 is rotated counterclockwise in FIG. 3, and the printing ribbon 8c is rotated. The print position is reached.

In this way, each time the keyboard is operated to print, the printing ribbon is lifted to the printing position, and after printing, the printing ribbon is quickly released from the printing position so that the printing can be confirmed.

However, this ribbon lifting operation requires driving the trenoid 9, which causes the rod 9a and the printing ribbon cassette 8 to
If you also add in contact with other people, it has the disadvantage of producing extremely loud noise.

Therefore, recently, electronic control has been used to maintain the lifted state and perform printing without performing a ribbon lift operation for each character when printing is performed continuously.

In other words, after printing, if the next printing key is pressed within a certain time period, the lift state is maintained and the ribbon lift noise and the time required for lifting are eliminated, resulting in quiet operation. We are planning to speed it up. This flowchart is shown in FIG. 4. If there is key human power in step 1, ribbon shift operation is performed in step 2, and step 3
Then, the type wheel 6 or the like selects the type that matches the key force, and in step 4, the printing hammer 7a is driven, and if it is not determined in step 5 whether or not the primary key force is available, the step is repeated. Return to 2 0 Next, in step 6 wait time T
It is determined whether n (for example, 200 m5) has elapsed, and if it has not elapsed, the process returns to step 5; if it has elapsed, the ribbon down operation is performed in step 7.

However, in W/W mode (written in word #i),
In L/L (line unit recording) mode, etc., if you want to record and print 70 characters that have been manually recorded in the memory using the key, all at once, control the ribbon lift and lift or lower the ribbon for each character printed.

However, in a typewriter that does not have such a mode and is only in the normal C/C (recording at about 1 character type) mode, the waiting time tn in Figure 4 is They are determined based on experienced operators; if a novice who is slow at printing operates these typewriters, the ribbon will move up and down every time it prints, which will not only cause noise but also cause problems with the ribbon lift. This has the disadvantage that the typing speed becomes even slower because the time it takes to print also adds to the overall printing speed.

[1:1 target] The present invention has been made in view of the above points, and its object is to eliminate the above drawbacks.

An object of the present invention is to provide a recording trace j4 whose recording operation can be controlled to suit the user.

〔Example〕

The present invention will be described in detail below with reference to one drawing.

5 and 6 are for explaining one embodiment of the present invention. FIG. 4 is an external view of a typewriter which is an example of the recording device δ, and FIG. 6 is a control block diagram of the recording device. It is. Components in the figure that are the same as those in FIGS. 1 to 3 are designated by the same reference numerals, and their explanations will be omitted.

In this embodiment, a selector dial D is provided near the keyboard 1, as shown in FIG. By operating this selector dial D with a finger, the holding time of the solenoid 9 can be controlled, and the lipophone, depending on the operator's ability, can be
The structure is such that a lift movement can be performed.

Incidentally, D may be a button or a numerical value input key, and is not limited to this.

That is, the selector dial D is connected to the volume 11 as shown in FIG.
is operated by the selector dial D, the output current is changed, this is digitally converted via the A/D converter 12, and this data is sent to the control device 1.
3, the control device 13 controls the drive device 15 backed up by the power source 14, and the solenoid 9 (
The holding time of the pulse motor 18 (which will be described later) may be controlled (
The controller is configured to be able to control the pulse motor 18 (which will be described later).

If such a structure is adopted, the operator can freely select the recording material for the holding time of the solenoid 9 according to the operator's ability, so that the ribbon lift operation can be performed according to the operator's ability. be able to.

Therefore, the generation of noise that accompanies ribbon lifting as in the prior art is prevented, and furthermore, it is possible to suppress a decrease in the overall printing speed caused by the ribbon lifting operation.

Since the configuration allows the operator to freely set the ribbon lift and down times, it is possible to perform the print ribbon lift operation according to the operator's ability. The accompanying noise can be prevented from occurring, and the time required for lifting the print ribbon can be eliminated from the overall printing time, thereby shortening the overall printing time.

Figure 7 is a perspective view of the recording section when lifting and lowering the ribbon is performed using a pulse motor and a cam.
FIG. 7 is a side view of the recording section similar to FIG. 7. In FIG. 7, a cam lever 1 is attached to the lower surface of the arm 8b of the printing ribbon cassette 8.
6 can freely rotate around a shaft 17 on the carriage body 2, and this lever 16 has an arm portion 16b, which is attached to the lower surface of the cassette arm 8b, and the cassette 8 The eccentric cam 19 and the other arm 16a are fixed to the output shaft of the hullless motor 18 due to their own weight.
are in contact with each other.

Therefore, by controlling the pulse motor 18 as shown in FIG. 8, ribbon lifting and ribbon down can be performed.

In addition, although the above explanation was about controlling the lift and down of the ribbon, it may be configured to control the amount of movement of the lift and down. In other words, the data to be recorded is rA] "J case and r" For example, in the case of data existing above the single-character recording area, such as "°", the user can simply change the amount of down movement, without having to lower the ribbon completely. can be visually observed, the next recording operation will be faster, and the recording speed will be significantly improved. or,
The same applies to left and right movement. Also, the above data is
It goes without saying that this movement, Fl, and amount can be easily determined using the input code, and furthermore, this movement, Fl, and amount can be similarly performed in the case of movement control using the above-mentioned solenoid and in the case of movement control using a cam.

In addition, the control of the time involved in the ribbon movement described above is not only variable through manual input, but also the smoothness of previous keystrokes can be measured by measuring the time between keystrokes and calculating the average. The time required for the movement of the ribbon, for example, the duration of the lift state, the duration of the down state m1. It may also be possible to control travel time, etc.
Further, the standard time may be stored using a back amplifier power supply so that the standard time is restored after a predetermined time has elapsed. Note that the above description can be similarly applied to other printers such as impact printers with hammers, wire dot printers, and 8-transfer type printers.

Next, in order to explain in more detail the control of the lift and down times of the ribbon, the control device 1 in FIG.
3 will be explained in more detail.

That is, as shown in FIG. 9, the data obtained by the volume 11 and the A/D converter 12, for example,
If the dial is 2 as shown in the table, the data corresponding to 100m5 (for example "00001010") is the control device 1.
3 is output. In the control device 13, as shown in FIG. 9, the above data is taken into the down counter 20, and the drive device 15 performs driving according to the data.
A control signal is output from the down counter 20 to the drive device 15. Also, a ROM like the one shown in Table 1 that corresponds to the dial
It can be configured in the same way even if it has a table.

Table 1 Next, determine the smoothness of the input stroke of the key 21 (the time between the key force and the next key force), which is a parameter related to the movement of the moving means that moves the member with the recording material,
A case will be described in which the time related to the recording operation is changed. A more detailed control block diagram of FIG. 6 is shown in FIG. 1O. In FIG. 1O, when the key 21 is input, the data is input to the key / From the key buffer 22, a recording control device 2 such as a text memory etc.
Data is sent to 6. On the other hand, a counter 23 counts how many characters of data have been input into the key buffer 22 within a predetermined time, and the count data
Based on a ROM table similar to Table 1 in the OM 24, data corresponding to a predetermined time is output to the drive device 15 via the latch circuit 25 at a predetermined timing. Note that it may be configured to use a timer instead of a key buffer and a counter to determine the time between key inputs, or to measure the time of multiple key inputs and calculate the average time between key inputs. It's okay.
