2 is a keyboard showing a conventional standard keyboard (uniform keyboard) arrangement.

Figure 3 is an overall perspective view showing the installation and use of the subject innovation.

4 is a block diagram of a conventional typewriter segment.

6 is a state in which the segment and the bracket is lowered in the state of FIG. 5 and the locking hook of the operating plate is locked.

7 is a state in which the segment yuba pushes the release piece of the operation plate in the state of FIG.

The present invention relates to an automatic release device of SAIFT KEY of the revised standard typewriter.

The revision standard keyboard type is the same format as the layout of the Korean computer keyboard. It is a revised format to correct the inconsistency between the Korean standard keyboard and the computer keyboard.

Currently, the Hangul standard keyboard and Hangul computer keyboard type is different from each other because of the different types of letter layout.

Therefore, the typewriter user cannot operate the computer, the computer user can not handle the typewriter, each can only handle the corresponding device.

Therefore, the typewriter keyboard is the same as the computer keyboard layout so that one person can handle both devices, so that they do not need to acquire skills separately, which is called the revised standard keyboard.

The key board of the revised standard keyboard is shown in FIG. 1, and the key board of the existing standard keyboard (unification board) shown in FIG.

In other words, the revised standard keyboard is used for consonants and support holes on the left side and is always dongle.

The group B on the right is used for both vowels without braces and vowels with braces.

The upper double consonants of group C locks are bases, and the lower vowels are used when there are no bases, and all of them are round.

The lower "TT" and "ㅗ" of group D are used to type middle vowels (ㅘ, ㅙ, ㅚ, ㅝ, ㅞ, ㅟ) that are not on the keyboard and are always floating.

Numbers and signs except for group D are always round, and the head type of group D is floating.

Here are some examples of typing using the revised standard keyboard.

If you want to type the first letter "a", you can type "oh" first and then type "ㅏ" to make it easier to type "a".

However, if you want to type the strong letter "strong", type "a" first, then press and release the SHIFTKEY (this should not raise the SEGMENT even if you press and release the shift key). And hit the support "o" in that state (segment should be raised to the normal position automatically) and you can type "strong".

In other words, the revised standard edition has a carriage that is floated at the time of the 2nd shift, which is the type of letters that need support, and the segment is automatically lowered and fixed at the time of printing the short vowel (ㅏㅑ ㅡ ㅡ ㅣ). Segment should not be solved at all, and the next character (support, ㄱ, ㅡ ㅡ ㅡ) and the carriage at the same time, the carriage turns into the east and the descending fixed segment is automatically released and raised to return to the position at the first shift. .

The present invention devised a device for automatically fixing the segment when the shift gear is pressed in the revised standard keyboard and pressing the support key or the space bar and simultaneously allowing the segment to rise and return to the attached drawing. If described in detail as follows.

First, the conventional configuration shown in FIG. 4 will be described.

Connected to the shift key of the keyboard, the segment man racket (2) is integrally fixed to the rear of the elevating segment (1) to be lifted and operated together, and the lever (3) adhered to the rear of the segment (1) Affix the operation plate 4 and place the side plate 5 on the front side of the operation plate 4 inside the segment 1 so as to be hit by the key bar 6, and on the back of the operation plate 4 the segment man bar. The rear end of the child (7) is fixed so that it can be advanced together. The front end of the segment man yuba (7) is connected to the front end of the bracket (2) by the connecting piece (8) and the bottom plate of the segment man yuba (7) (9). ) Is configured to touch the escapement one by one.

In this known configuration, the automatic lock and release device of the present invention is installed in front of the segment man racket 2, which will be described with reference to FIGS. 3 and 5.

The device of the present invention is to install the horizontal axis 11 in the position immediately below the front end of the segment man racket (2) by fixing the operating plate 12 to the horizontal axis 11 to be retracted before and after the operation of the operating plate 12 At the top of one side, an L-shaped locking hook (13) is formed so as to be positioned in line with the segment man racket (2), and the release part (14) is integrally formed at the front end so that the bottom plate of the segment man yuba (7) (9) to be located in front of the inner wall surface of the operating plate 12 to form a protruding piece 15 so as to be located in front of the needle bar 17 connected to the space bar 16, the operating plate 12 is a spring (18) It is configured to be pulled toward the segment 1 by).

Since the operating plate 12 is pulled by the spring 1, the present invention has the locking hook 13 of the operating plate 12 in the state in which the segment 1 is raised. ) Is connected to the end, as shown in FIG.

In this case, the segment 1 may be positioned in the first shift, the carriage may be moved, and consonants and long vowels (uncollected vowels ㅡ ㅡ ㅣ) may be continuously typed.

In this state, press the shift key to type the supporting letters, and the segment (1) descends, and the combined segment bracket (2) also descends, and the lock ring (13) leaning against the front end springs. By the pulling force of (18), it is caught in the state of FIG. 6 while being leaned to the upper part of the lowered racket 2 instantaneously, so that the racket 2 is fixed in the lowered state.

Therefore, the segment (1) is automatically locked without a separate shift lock key, and the segment (1) is never released because the carriage is floating even when typing a short vowel (ㅏㅑ ㅡ ㅡ).

In this state, when the supporting type is typed, the supporting type is typed, and the carriage changes to the east, and the key bar 6 strikes the side plate 5 of the operation plate 4 as shown by the arrow in FIG. As the base plate 9 in the middle pushes the release piece 14 of the operating plate 12 in a moment as it moves forward, the entire operating plate 12 is pulled out as shown in FIG. The segment 1 is lifted upward and returned to the position at the time of the first stage shift as shown in FIG.

Also, since the protruding piece 15 of the operating plate 12 is located in front of the depilating piece 17 connected to the space bar 16, the depressing piece 17 is also provided with the protruding piece 15 even when the space bar 16 is pressed. By pushing the lock state of the segment 1 can be automatically released.

The present invention has the effect of being able to immediately type without having to operate the shift lock key separately because the Segment (1) is automatically lowered when the Segment (1) is lowered and the Segment (1) is automatically released. In particular, when the standard type of existing typewriter is transformed into the revised standard type, it can be used only when the automatic lock and release device is applied, so it is easy to install the typewriter without changing the type without changing the type. It is designed to utilize existing typewriters usefully.
