Abstract

PURPOSE:To enable to enhance printing efficiency and printing speed, by a method wherein an operation for performing the subsequent printing immediately after a printing action or an operation for providing a predetermined stand-by period is selected in accordance with the kind of a printing means, in a printer comprising a plurality of printing means. CONSTITUTION:Where a mode signal M is a high-level signal and a non-impact printing mode is designated, a change-over circuit 17 outputs a spacing executing signal BUSY1 as a space busy signal BUSY0, and a master controlling part transfers the subsequent printing data P immediately after the outputting of step pulse signals phi1-phi4 from a step-controlling circuit 13 in response to data P is completed. On the other hand, where the mode signal M is a low-level signal and a printing mode other than the non-impact printing mode is designated, the circuit 17 outputs a signal BUSY2, and a delay circuit 16 so functions that the subsequent printing data P are transferred after a predetermined delay time has elapsed from the moment the outputting of the step pulse signals is completed. Accordingly, the stand-by period between printing actions can be omitted under control depending on the printing mode, and printing efficiency can be enhanced.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a printer, and more particularly to an impact printer equipped with a non-impact printing device.

Conventional daisy printers are suitable for high-speed printing of characters and symbols, but recently, daisy printers have been equipped with non-invacuum printing devices that use ballpoint pens, etc., and printers that can output graphical information such as graphs at high speed have become available. is being developed. Normally, in an impact printer such as a daisy printer, each ljl! By transferring the next print data C after a predetermined waiting time until the control vibration of the structure disappears, the print operation is stabilized and the print quality is improved. On the other hand, in a non-incubation printing device that uses a ballpoint pen or the like, the head is always on during the printing operation, so no control vibration occurs and there is no need to provide a waiting time. Therefore, in a printer equipped with a non-invacuum 1 printing device,
During the printing operation by the printing device, it is necessary to omit the waiting time provided between printings. If a waiting time is provided even during printing by a non-invacuum printing device, a problem arises in that the printing speed becomes slow. for example,
When a line segment as shown in Fig. 2 is printed using a non-increase printing device, the line segment of 1/1 (45°) has a
The 5P (space) and ILF (line feed) operations are repeated alternately, and the 2SP and ILF operations are alternately repeated for the 1/2 (2'2.5°) line segment. Since a busy signal is output for each SP (space) and LF (line feed) operation and a predetermined waiting time is required, the printing speed is more than twice as slow as when there is no waiting time.

Purpose The present invention has been made to solve the above-mentioned problems.
The purpose is to improve printing efficiency and printing speed by omitting waiting time during printing operation by a character device.

Configuration The configuration of the present invention will be described below based on specific examples. FIG. 3 is a block diagram showing one example of the configuration of the printer of the present invention. A master control section 1 receives a data signal 1 from the outside, determines the content of the data, and sends a selection control section 2, a space control section 3. Line feed control section 4. Hammer control section5. Data is transferred to the non-impact head control section 6. Each of the control units 2 to 6 selects a type according to the transferred data.

Controls the operation of i'e 11.

Each of the control units 2 to 6 outputs to the master control unit 1 a busy signal indicating whether or not the next data can be received. When each busy signal is “O”, master control I group 1 can output the next data to each control unit 2 to 6, and when the busy signal is 1”, master control unit 1 outputs the next data. In addition, under the control !U of the master control unit 1, the mode setting unit 12 is set to “1” while the non-print 1-print mode has been instructed, and “1” for other poems.

A 11-step motor is used to drive the J
5, the space f specified by the external data signal ② is converted into the number of pulses given to the step motor by the master system pO section 1 as J:, and is given to the space system 611 section 3. According to this data, the space control unit 3
Then, a step pulse signal φ; to φ4 having a predetermined pulse width and phase shift is created. In addition, a space busy signal B informs the master control unit 1 of the space system 1711 Hiiragi Ryo.
USY○ is created.

Shown in Figure 4! III < , the space control unit 3 includes a step control circuit 13 that creates a step pulse signal using data P from the mask fDIJ sin Gf+1;
a timer 14 that determines the pulse width of the step pulse;
Subtractor 1 for counting the number of step pulses
5, a delay circuit 16 for delaying the space execution signal BUSY1 output from the step control circuit 13 even after the space control ends, and a delay circuit 16 for delaying the space execution signal BUSY1 outputted from the step control circuit 13 even after the space control ends; It consists of a switching circuit 17 for switching the delay signal BUSY2 and outputting the space busy signal BUSYO. FIG. 5 shows step pulse signals φ1 to φ4° and space execution signals BUSY1. The relationship between the space execution signal and the delay signal BUSY2 is shown, and timing t-1- is shown. At the same time as the step pulse signals φ1 to φ4 end, the space execution signal BUSY1 becomes 0'', but the delay signal BUSY
SY2 then remains at 1111+ for a delay [, y, d.

Next, the operation of the space control section 3 in FIG. 4 will be explained. First, data P from the master system O11 section 1 is
is set in a counter in the step control circuit 13.

When the data is set to 1 to 1, the step control circuit 13 outputs the initial state of the step pulse signals φ1 to φ4 shown in FIG. ~ to create a pulse with a predetermined pulse width. When the timer 14 times up, the subtractor 15 subtracts 1 from the counter in the step control circuit 13, and the step control circuit 13 causes the timer 14 to start at 1 again. In this way, the operation is performed one step at a time, and is repeated until the counter in the step control circuit 13 reaches O. When the counter reaches O, the sending of step pulse signals φ1 to φ4 ends. Further, the space execution signal B output from the step control circuit 13
USY1 becomes "1" when sending out the step pulse signals φ1 to ψ4 starts, and becomes "0" when sending ends.

When the mode signal M is 1'' and the non-impact printing mode is specified, the switching circuit 17 outputs the space execution signal BLISY1 as the space busy signal BIJSYO.
Therefore, the master control section 1 can immediately transfer and overwrite the next print data after the step pulse signal has been sent. On the other hand, when the mode signal M is '0'' and the printing mode is other than the non-in or pact printing mode, the switching circuit 17 outputs the space busy signal 5usyo as the delay signal B.
Since LISY2 is output, is it master control? 11 part 1
It becomes possible to transfer the next print data after a predetermined delay interval d after the end of sending the step pulse signal. Line feed i (J III section 4 can also be configured using the same block diagram. In short, the non-interactive 1-print mode is spaced 1' and the waiting time in line feed operation. 2, the printing speed when printing a line segment as shown in FIG. 2 becomes extremely fast.

-Effects As described above, the present invention allows for simple addition of circuits.
It is possible to control the waiting time between prints to be omitted by changing the print mode. As a result, there is an effect of increasing printing efficiency and printing speed. It should be noted that the present invention is not limited to the above-described embodiments, but can be modified and applied in various ways without departing from the technical scope of the present invention. For example, it is not limited to a combination of a daisy printer and a printing device using a ballpoint pen, but also a combination of a printing device that requires waiting time to generate controlled vibrations and a printing device that does not require waiting time. It is possible to apply it to a combined sliding type printing device. In addition, in the embodiment, control of waiting time associated with space operation and line feed operation was explained, but it is also possible to apply it to other types of control. The waiting time after the selection operation and the hammer operation may be omitted.
