The present invention relates to an automatic release mechanism of the upper lock which is configured to automatically release the operated SHIFT KEY in the mechanical type standard keyboard Hangul typewriter.

The revised standard keyboard is divided into four groups of 14 consonants and 12 vowels. A: group is used as consonant and support hole, which is a donkey where CARRIAGE ASS'Y is always moved. Used as a common vowel (long vowel) and a vowel with a stand (short vowel), a vowel without a stand becomes a donkey (a bundle bundle is moved), and a vowel with a stand supports a floating key The bundle is not moved), C: the upper double consonant of the group is the base and all donkey, and D: the lower "ㅗ" and "TT" are the middle vowels (ㅘ, ㅚ, ㅙ, ㅝ, It is always a floating key, used when typing ㅟ, 키).

Therefore, the numbers and various symbols except the D group are always the same key, and all the keys except the "," and "?" At the top of the D group are the same keys.

Therefore, in the related art, the typing method is complicated and the typing speed is low due to many group motions that are inevitably made due to the basic driving of Hangeul formation.

For example, when you type "not", 1) type "ㅇ", 2) press the upper left key, 3) type "4", and 4) press the right upper key, 5) press the "b" support. Type

As mentioned above, the "not" Chinese characters must be typed in five movements, that is, a complicated and difficult defect must be pressed to press the upper left and right letters that form one letter.

In order to solve the above-mentioned drawbacks, the present invention uses a typewriter keyboard composed of 14 consonants and 12 vowels. On the ulder, the operation lever with the release piece is formed at the latching jaw, the projection and the bending end, and the coal spring is installed and the trip bell crank moving forward and backward during the donkey type is pushed and operated by the lever of the operation lever. It is designed to make typing simpler and faster by not having to press the left and right upper wheels when typing a long letter by configuring the home holder to be automatically lifted and lifted. Referring to the drawings in detail as follows.

The bending support piece 3 is installed on the bottom part rail 2 of the typewriter main body 1 to build up the catch shaft bar 4, and is caught by the support piece 5 'installed on the letterpress holder 5. A coil spring (7) is formed between the jaw (6) and the engaging projection (6 ') and the operating lever (7) formed with the release piece (6 ") at the bent end with the support shaft (7'). 8) is to be configured to be associated with the trip bell crank (9).

In the figure, reference numeral 10 denotes an offset connecting link, and 11 denotes a printing distance adjusting screw.

When the effect of the present invention is described in detail, the constitution of the present invention is generally used by attaching a constitution of 14 consonants and 12 vowels to a mechanical typewriter (two inputs and four outputs) of Korean typewriter. As shown in the figure, the operating lever 7 is released from the locking shaft 4, and when typing a letter with a donkey support such as the letter “in” or “both”, type “ㅇ” and the left upper key When pressed, the actuating lever 7 installed in the letterpress holder 5 is lowered along with the actuation force of the coil spring 8, and when the actuating lever 7 is pulled momentarily, the actuating lever 7 is raised to the point 7 '. The concave inlet portion 6 "between the locking jaw 6 and the locking projection 6 'is attached to the locking shaft 4 mounted on the bending support piece 3 mounted on the cart rail 2, and fixed. You can type “ㅏ” in the 1st opponent as it is in the lowered state as in 2nd If you type the donkey support "b" or "ㅇ" in succession, the speech between tripbell crank 9, which is inevitably activated when the donkey is typed, pushes the release piece 6 formed at the bent end of the actuating lever 7. As the operation lever 7 is moved in the circular direction with the support shaft 7 'as a point, the coil spring 8 is released from the locking shaft bar 4 formed on the bending support piece 3 of the cart rail 2. The upper key is automatically released by returning from the second degree state to the first degree state due to the resilience force of 4, so that the user does not have to press the left and right upper locks alternately as in the prior art, so the four movements are It can be reduced by the movement, so it is easy to learn typing, faster typing, simple structure, easy to manufacture, and can be installed on existing typewriters. It has such a practical effect.

Claims (1)

As shown in the drawing, a bottom supporter (2) on the bottom of the batter basic body (1) is installed on the curved support piece (3) to build up the catch shaft (4), and a support piece (5) installed on the letter holder (5). ') Has a concave inlet 6 "formed between the engaging jaw 6 and the engaging projection 6', and an operating lever 7 having a release piece 6" formed at the bent end with the support shaft 7 '. The automatic release device of the upper lock, which is configured to be cooperatively operated by the trip bell crank (9) by coaling with the coil spring (8).
