Abstract

PURPOSE:To save consumption of ink ribbon, when making a correcting operation with a correction ribbon being placed between a recording medium and the ink ribbon, by controlling the feeding quantity of ink ribbon variably based on specific conditions. CONSTITUTION:Upon provision of a correction command, CPU16 reads out a feeding quantity data N corresponding to the width of type of a character to be corrected from a correcting time ink ribbon feeding quantity data memory 18 in ROM17, and sotres said data N in a correcting time ink ribbon feed counter 20. Upon finish of correction of character, a step motor 24 for feeding an ink ribbon is rotated. The ink ribbon feeding quantity data N stored in said counter 20 is employed for said rotation control, and the content of counter is subtracted one by one every time when the step motor rotates by single step, and the rotation is stopped when the content goes to 0, thus finishing correction. When correction is made, the ink ribbon is fed by a predetermined width corresponding to the width of type, thereby it can be utilized effectively within minimum feeding quantity range without causing breaking nor cutting.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a recording device, and more particularly to a recording device having an ink ribbon for recording and a correction ribbon for erasing already printed characters and symbols. It is.

[Prior Art] Conventionally, in a recording device having a type impact recording head such as an electronic typewriter, already printed characters,
Devices with correction ribbons for erasing symbols are known.

The correction ribbon of this type of device is constructed by coating a base material with a material that removes or covers the ink of the already printed characters, and by embossing the same type on the already printed characters through this correction ribbon. Erase already printed characters.

In addition, in a device having an ink ribbon and the correction ribbon described above, recording or correction is performed by positioning either the ink ribbon or the correction ribbon in front of the recording head. Furthermore, an apparatus has been considered in which the correction ribbon is shifted and the printed characters are printed through the ink ribbon to correct the characters.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional example, the amount of feed of the used ink ribbon wound for each correction is always a constant length for each correction operation, regardless of the type of type being corrected. It was decided that For example, regardless of the width of the printed characters to be corrected, it was specified that an appropriate amount of ink ribbon should be sent for each correction so as to match the maximum width of the printed characters to prevent damage or breakage of the ink ribbon.

Therefore, there is a problem in that the usage efficiency per area of the ink ribbon decreases, and the frequency of ribbon replacement increases accordingly.

[Means for Solving Problems 1] In order to solve the above problems, the present invention includes an ink ribbon for recording and a correction ribbon for erasing recorded characters or symbols, and the recording medium and ink are connected during correction operation. In a recording apparatus that interposes a correction ribbon between ribbons and performs a correction operation through the ink ribbon, a configuration is adopted in which the feed amount of the ink ribbon is variably controlled based on predetermined conditions during the correction operation.

[Function] According to the above configuration, the ink ribbon consumption amount can be saved by variably controlling the ink ribbon feeding amount during correction based on predetermined conditions.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIGS. 1 and 2 are perspective views of the main parts of a type impact type recording device. A carriage 1 is slidably attached to a guide shaft (not shown) and moves back and forth along a platen 2. FIG. Daisy wheel 4 is on the carriage l.
A recording head 3 for striking printed characters is provided and faces a daisy wheel 4. Further, an ink ribbon cassette 5 is detachably mounted on the carriage 1, and the ink ribbon 6 pulled out from one arm 5a is wound onto the side arm 5b by a ribbon feed motor (not shown). The ribbon is picked up, but along the way it is supported by a ribbon guide 7 and conveyed through between the daisy wheel 4 and the recording paper.

As shown in FIG. 2, a supply reel 9 is rotatably attached to the left side of the carriage 1, and a correction tape 8 can be detachably attached to the supply reel 9. Further, rollers 12 and 13 are rotatably attached to the printing side of the carriage 1. On the other hand, on the right side of the carriage 1, there is a rotating arm 11 that is rotatable, and a roller 14 is rotatably attached to the tip of this rotating arm, and a winding roller 14 for winding up the correction ribbon is located in the middle. A reel IO is rotatably attached. This rotating arm 11 is vertically swung about a fulcrum 15' by a cam 15 rotated by a drive motor (not shown). With this vertical movement, the take-up reel 10 rotates and winds up the correction ribbon 8.

The correction ribbon 8 pulled out from the supply reel 9 is attached to the roller 1
2.13, the ink ribbon 6 is kept passing through the re-platen 2 side, and is wound onto the take-up reel 10 via the roller 14 attached to the rotating arm 11.

Next, the mechanical operation of the recording and correction mechanism described above will be explained.

To perform normal recording, the rotating arm 11 is in a horizontal state as shown in FIG. 3, and the correction ribbon 8 is positioned below the ink ribbon 6 as shown in FIG. When the recording head 3 is operated, the characters on the daisy wheel 4 are struck by the recording head 3 onto the recording medium on the platen 2 via the ink ribbon 6, and normal character recording can be performed. On the other hand, when a correction operation is desired, the cam 15 is rotated as shown in FIG. 5, and the tip of the rotating arm 11 is raised. In this state, as shown in FIG. 6, the correction ribbon 8 crosses the ink ribbon 6 at the recording position and on the platen 2 side. When the recording head 3 is operated in this state, the correction ribbon 8 is struck via the ink ribbon 6, and a correction operation is performed.

When the rotating arm 11 moves up and down once, the correction ribbon 8 is wound up by one character on the take-up reel 10.

Here, when the rotating arm 11 moves up and down once every time one character is corrected, the correction ribbon is fed by one character, but the ink ribbon 6 is also hit, so in order to prevent the ink ribbon from being damaged or cut, correction is necessary. Each time the operation is performed, the ink ribbon 6 is also transported by a transport mechanism (not shown).

In this embodiment, the feed amount of the ink ribbon for each correction is controlled by the feed amount specification code corresponding to the print width when correcting characters with different print widths (for example, uppercase M and lowercase letter i). It has become. This is to reduce the amount of ink ribbon consumed during correction.

The configuration for controlling the ink ribbon feed amount when correcting characters is shown below.

FIG. 7 shows a control system of a recording apparatus having the recording mechanism shown in FIGS. 1 and 2. In FIG.

In the figure, the reference numeral 16 is a CPU consisting of a microprocessor element, etc., which controls the entire device according to a program to be described later stored in the ROM 17, and 17 is a ROM.
An ink ribbon feed amount data memory 18 for correction is included. The correction ink ribbon feed amount data 18 is composed of, for example, an 8-bit binary number, and 16 states from O to 15 can be output, and one state of this data drives the ribbon feeding mechanism. 1 of step motor 24
It is designed to correspond to the steps.

This is determined corresponding to each corrected character, and the setting and feeding amount of the ink ribbon at the time of correction can be freely set. Further, the amount of feeding of the ink ribbon may be less than the character width, that is, the ink ribbon may be fed in an overlapping manner, as long as the ink ribbon is not damaged or cut.

19 is a RAM, and this RAM 19 includes an ink ribbon feed counter 20 during correction.

Reference numeral 21 denotes a printer mechanism section, which includes a printing mechanism 22 having the configuration described above, a correction mechanism 23, and a step motor 24 for feeding the ribbon. Note that 25 is a keyboard for inputting various commands to the apparatus.

Next, refer to the flowchart in Figure 8 to determine whether the CPU
The control of the ink ribbon feeding amount carried out by 16 will be explained below. The procedure shown in FIG. 8 is stored in the ROM 17 as a program.

First, in step S1, the CPU 16 determines whether or not there is a modification command input, and if so, in step S2, the CPU 16 determines and specifies the character to be modified.

Next, corresponding to the character to be corrected specified in step S3, the correction ink ribbon feed amount data in the ROM 17 - the feed amount data N corresponding to the print width of the corrected character from the memory 18
is read from the ROM and stored in the correction ink ribbon feed counter 20 in step S4.

In step S5, the above-mentioned mechanism performs a character correction operation, and when the correction is completed, the ink ribbon feeding step motor 24 is rotated in step S6. For this rotation control, the ink ribbon feed amount data N stored in the ink ribbon feed counter 20 at the time of correction in step S4 is used, and the contents of the counter are subtracted one by one as the step motor rotates one step (step S7). )
, when the content becomes 0 (step S8), the rotation of the step motor 24 is stopped and all corrections are completed.

According to the above configuration, when making corrections, the ink ribbon is fed in increments of a predetermined width corresponding to the type width of the characters to be printed, so that the ink ribbon can be fed within the minimum feed amount range without damaging or cutting the ink ribbon. The ink ribbon can be used efficiently. Further, in this embodiment, since the correction operation can be performed by shifting only the correction ribbon, the structure of the apparatus is simple and inexpensive.

In the above, when making corrections, the ribbon is wound up after the recording head is driven, but the previous correction characters are memorized and
The same effect as described above can also be obtained in a configuration in which the ink ribbon is wound up prior to driving the recording head during correction in accordance with the previously corrected character width.

[Effects of the Invention] As is clear from the above description, the present invention includes an ink ribbon for recording and a correction ribbon for erasing recorded characters or symbols, and the gap between the recording medium and the ink ribbon during the correction operation. In a recording apparatus that performs a correction operation through the ink ribbon by interposing a correction ribbon in the ink ribbon, a configuration is adopted in which the feeding amount of the ink ribbon is variably controlled based on predetermined conditions during the correction operation, so the configuration is simple and inexpensive. This has the excellent effect of reducing ribbon consumption when modifying recorded characters.
