DETAILED DESCRIPTION OF THE INVENTION The present invention is a training machine for learning the operating skills of foreign language typewriters, language word processors, computer keyboards, etc. It is related to.

Traditionally, in order to learn how to operate keys on a keyboard, you had to use a typewriter directly and practice while watching your own progress or with a teacher. There was no training aircraft itself.

Light j is LL round 几 1 reciprocal length, plate light is removed, use for needs such as C type writers and use for 1 111 j are the same 11. 'lL'can't be done and always requires '1', so if it's used, there's no chance to practice.

Additionally, Japanese word processors or computers are expensive, large and inconvenient to carry, and there are restrictions on where you can practice.

Furthermore, it is difficult to judge the level of proficiency and it is not easy to select practice content, and inappropriate practice content may delay the acquisition of technical skills.

The present invention has been developed in view of the above, and its purpose is to provide a simple key operation training device that allows users to practice at any time and place, depending on their level of proficiency.

The structure of the present invention and the method for performing IJ will be explained based on FIG.

C is a key IE operation detection means for detecting that the 4-1A stomach operation has been performed correctly for each 4-operation.

D controls the movement of the sheet B to move it forward based on the detection signal from the detection means C. There is a forward movement means for moving B forward little by little intermittently.

[ is a clock means for counting a predetermined time from the start of the operation.

Reference numeral G denotes a key operation speed determination means for determining whether a certain key operation has been performed within a predetermined time by the timer F.

Reference numeral 11 denotes a backward movement means which does not return the seat B to the original starting position again if the key operation is judged to be slow by the judgment means G-.

The present invention has the above configuration, and the sheet Bi,
Ls The practice content differs for each lesson depending on the level of proficiency, and each key operation is il: L. Sheet B moves forward intermittently every time the lesson is performed, and the lesson is not completed within the specified time. When this occurs, Seas 1 to B are moved back to their original starting positions, and the same lesson can be repeated again, allowing the user to practice key operations according to his/her level of proficiency.

Embodiments of the present invention illustrated in FIG. 2 and subsequent figures will now be described.

FIG. 2 does not show the appearance of one embodiment. On the upper surface of the casing 1, which is shaped like a horizontally long rectangular parallelepiped, there is a keyboard 2 in which a plurality of keys 9 are arranged according to JIS standards, and on the other side there is a display window 3, which is horizontally long on the left and right, on which key operation instructions are displayed. ``Enter this letter'' on the casing of window 3.

Alternatively, an arrow pointing to the letter to be typed is printed along with the text "TYPE OLD S LETTER."

Further, a timer display lamp 4 is provided to the right of the text and the arrow to indicate the passage of time.

The wooden casing 1 has a rectangular box shape with an upper M1a consisting of a top surface, front, rear, left and right sides, and a back cover 1b on the lower surface, and a cylindrical storage CIS 7a is located on the right side of the interior. A sheet end roll 6a in which five rolled sheets 5 are wound in a spiral manner is rotatably pivoted on the front and rear sides.
On the left side, a cylindrical storage section 7b having a central axis in the front-rear direction and a sheet end roll 6b are provided to store the rolled sheet 5.

The rolled sheet 5 wound around the end roll 6a of the sheet 1 advances to the left through the gap between the plate 8 and the key 9, and its tip is passed through the slit-shaped opening 7C of the circle 'fJ-shaped storage section 7b. The sheet enters and is stored in the cylindrical storage portion 7b by the sheet end roll 6b which is rotatably pivoted.

On the right side of the cylindrical storage portion 7b, a ratchet step-up coil 10 is fixed with a screw 13 to a square-shaped fixing member 12 whose side surface is fixed to the substrate 8. A fixed iron core 11 is fitted inside 1o in the direction of the left and right central axis.

A relay mechanism suction shield 14 is located on the right side facing the 171 constant core 11, and a spring 1 is perpendicular to the U-shaped fixing member 12.
5, the ratchet step-up coil 10 attracts the suction plate 14 when current flows through it, and returns to its original position when the current is turned off.

In the groove provided in the upper center of the suction plate 14, a support shaft is installed in the front-rear direction, and a ratchet pawl 16 is pivotably attached to the support shaft. Due to the spring 17, the force at A5 in FIG. 5 is always applied in the counterclockwise direction.

Further, below the ratchet pawl 16, a fixed iron core 18 and a ratchet pawl release coil 19 are fixed to the U-shaped fixing member 12 by winding the fixed iron core 18 with the central axis in the vertical direction.

The ratchet wheel 2 engages with the ratchet pawl 16.
0 is provided integrally with the rotating shaft 21, and the rotating shaft 21
are rotatably pivoted by support members 22 and 23 arranged at the front and rear ends and fixed to the base plate 8.

A pair of sprockets 24, 25 are further attached to the rotating shaft 21 near both ends, and a gear 26 is integrally attached to the center, and the sprockets 24, 25 are provided near both ends of the roll sheet 5 at equal intervals. Engage with the hole and chant 1: J-
Move sheet 5.

In addition, a motor 27 is attached to the hand 0ζ■ of the loveet mechanism at the J'' handle 8, and its drive shaft is integrally provided with a giflet 28 at the tip, and a current flows through the motor 27. , the gear 28 protrudes together with the drive shaft and meshes with the gear 26 that is integrally attached to the rotating shaft 21, and the sprockets 24 and 25 are rotated as shown in FIG.
The roll sheet 5 can be moved backward by rotating in the l and 'iH1 directions, and when the current to the motor 27 is cut off, the gear 28 is moved away from the gear 26 with a pull /υ.

This machine has the sheet moving mechanism 8 as described above, and when moving the rolled sheet 5 forward, when a current is applied to the ratchet step-up coil 10, the suction plate 14 is attracted to the left. (see Fig. 5), the ratchet pawl 16 passes one position south of the tooth wheel 20, and when the current is cut off, the spring 15 returns to its original position, causing the ratchet pawl 16 to push the teeth toward the ratchet wheel 20. By rotating one pitch counterclockwise, the roll sheet 5 is moved a certain distance to the left by the sprockets 24 and 25, which rotate together with the ratchet wheel 20 (71-).

Therefore, by intermittently passing current through the ratchet step-up coil 10, the roll sheet 5 is gradually moved forward.

When the roll sheet 5 is moved backward, current is continuously applied to the ratchet pawl release coil 19 and the motor 27, and as the ratchet pawl release coil 19 operates, the ratchet pawl 16 is sucked downward, and the ratchet pawl 16 and the ratchet wheel are The gear 2 at the tip of the drive shaft is disengaged from the gear 20, and the motor 27 is driven at the same time.
8 and the gear 26 of the rotating shaft 21 mesh with each other and rotate, so that the roll sheet 5 can be continuously moved backward by the sprockets 24 and 25.

Eight blade switches 29a to 29h are arranged in parallel to the rotating shaft 21 and on the right side of the sheet moving mechanism described above.
Each blade switch 2 is fixed to the board 8 and
Contact pieces 30a to 30h protrude to the left from 9a to 29h, and the contact pieces 30a to 30h are bent into a dogleg shape so that the contact portions emerge upward from slit-like grooves 31 provided in the substrate 8. (See Figure 4).

state.

A dry cell battery 32 is installed inside the bookshelf between the sheet moving mechanism and the feed roll 6.

Next, the switching mechanism using the gear 9 will be explained with reference to j and t in FIG.

The gear 9 consists of a bushing button 33, a support member 34, and a compression spring 35 interposed therebetween.
A34 is fixed to a fixing member 36 provided above the substrate 8 with a gap therebetween.

! ;t +N 8] and print group (fzPcB3
7 is glued (13), and a circuit is printed on its surface.

The roll sheet 5 moves just above the PCB 37, and a mylar sheet 38 is further laid on top of the roll sheet 5.

On the lower surface of the mylar sheet 38, wiring for a hot side (high potential side) circuit is printed.

Therefore, when the rolled sheet 5 moves and comes under a key with a hole provided at a predetermined position in the rolled sheet 5 and the button 33 of the key is pressed, the tip of the button 33 is pressed. pushes the mylar sheet 38 down into contact with the PCB 37.

Then, the wiring of the hot side circuit of Mylar sheet 38 and the PC
The switch contact on B 37 becomes conductive, and the switch of the key is turned on.

When there is no hole in the roll sheet 5 below the bush button 33, even if the bush button 33 is pressed, the roll sheet 5 blocks the contact between the mylar sheet 38 and the PCB 37, and the switch remains in the OFF state. .

The reason why the mylar sheet 38 is interposed to perform the switching operation is that the hole in the roll sheet 5 gets caught on the tip of the button 33, preventing the opening from interfering with the movement of the sheet 5. to ensure smooth movement.

Next, the positions of the holes provided in the sheet 5 will be explained.

The key layout on the keyboard 2 is based on the JIS current standard, and there are 5 lines including the space key ("1" line, "Q"
11 lines, A 11 lines, it Z 11 lines, space key line).

The roll sheet 5 is intermittently moved forward to the left.

A hole is set at a predetermined position on each key switch line of NE.
(See Figure 7).

In addition, the keys 9 on the keyboard 2 are classified into 6 groups (J5).The standard for this classification is that keys with a short press interval (3u), that is, keys that are far apart, are grouped together into one group.Group 1 The key belonging to is 1.7,
E, O, G, Z, M, keys belonging to group 2 are 2.8

,to,V,/,The keys belonging to group 5 are 5,Q,U,
The keys belonging to DlL, B1 group 6 are 6, W, I, F
, :, N, and the space key does not belong to these groups.

When a certain key is to be pressed, a group for that key is automatically specified in advance, and keys for which no group is specified are aligned with the holes provided in the roll sheet 5. Even if the key is pressed, it can be determined that the key operation was not performed correctly.

In other words, the positions of the keys on the keyboard have widths from left to right, and the roll sheet 5 moves little by little to the left. Since there are many cases in which the keys (holes to be created) match, a group is specified in order to select the correct key from among the matching keys.

However, there is still a possibility that the keys in the same group coincide with the holes provided in the roll sheet 5, so even in that case, the keys in the same group are at position 77. Since the press time between the keys is extremely rare, the probability that a key operation error is determined to be incorrect can be made extremely small.

This group designation is for the blade switches 29a to 29.
J to the six blade switches 29a to 29f behind h.
The switching of this blade switch is performed by a hole on the group switch line provided in the roll sheet 5, and 1) GrD, 15WLIN[, Grp

There are six group switch lines: W LINE, Grp, and 6SW LINE, and holes are provided at predetermined positions on the lines.

In addition, the roll sheet 5 has holes for detecting the start position and end position of each lesson.

Upper side of LINE and 5PACE KEY LINE
They are listed at a constant pitch below.

The distance between adjacent keys on the left and right is 19.05m,
This interval is divided into 6 equal parts, 3.175 m, which corresponds to 1 step of movement m, that is, 8 unit movements of the roll sheet 5 by the sprockets 24 and 25.

One part of the roll sheet 5 has the letter and L of the key to be pressed.
The ESSON number etc. are printed and displayed on the display window 3 on the top surface of the casing.

The example shown in the roll sheet 5 shown in FIG.
The keys are operated in the order of IIY, JIIIG, and RTUY.

The substrate 8 is now located at the position indicated by the vertical broken line in FIG.
It is assumed that there is a slit-shaped 1fi31 installed in J, and the contact portions of the IBF+IR pieces 30a to 301) protruding from the route switches 29a to 29h are located.

At this point, the GRP of roll sheet 5 is 33W1.
There is a hole 1 at the intersection of 1N1: and the broken line, so with the blade switch 29c in the ON state and group 3 specified, the [1

-0) A hole is also made at the position marked J, and when the J key is pressed, a control circuit (to be described later) determines that the key has been pressed correctly.

In this case, even if another key is pressed, in most cases there is either no hole above the key, or even if there is, it does not yield to group 3.

is ONL, and detects that the roll sheet 5 is at the start position.

Here, when the J key is pressed correctly, the rolled sheet 5 moves one pitch to the left, and when an incorrect key is pressed, the rolled sheet 5 does not move and remains in the same state.

When the J key is pressed and the roll sheet 5 moves forward, this is the same as moving the broken line one pitch to the right in FIG.
A hole is drilled at the position marked with the symbol H where it intersects with the LINE, and group 2 is specified. When the hole is drilled and the H key is pressed, it is determined that a correct key operation has been performed.

In this way, two holes are made at predetermined positions on the roll sheet for each character shown in the example.

Note that space key ~ is controlled by one hole J,
It's becoming a sea urchin.

Also, in Figure 7, the characters marked with “’” in jJ3 are
This shows the position of the holes in the 12 and a half repeating parts.

Next, the switching circuit and the drive circuit for the coil 10, 19, motor 32, etc., which are operated by the above key operations, will be explained based on FIG. 8.

The circuit in the upper part of the figure is for key operation and blade switch 28.
This shows a switching circuit from 0 to 2811.
Blade switches 29 are activated by eight switches that are turned ON when the holes provided in the roll sheet 5 match the key operations, and the holes provided at predetermined positions in the roll sheets 1 to 5.
A to 29h indicate switches that are turned ON when a manual operation is performed.

The F side wiring of each key switch is connected to the high potential side (hot side) of the power supply 40, and the F side wiring (also connected to one contact of the blade switch in each group, and the other side of the blade switch All contacts are connected to the radiator 1 to the step-up coil 10.

Therefore, only when the blade switch is ONL and any key switch in the group is 0NLk, current flows to the ratchet step-up coil 10 and the sheet can be moved one step.

The space key switch is special, and if you turn it on, you can avoid operating the ratchet step-up coil regardless of the blade switch.

The circuit for controlling the movement of the roll sheet 5 can be roughly divided into three parts: a timer control circuit, a sheet high-speed jW circuit, and a sheet retraction circuit.

The timer control circuit consists of a timer circuit 41 and changeover relay switches 42 and 43.The timer circuit 41 is activated when a timer start button 44 (same as the start button on the keyboard) is pressed, and measures a predetermined time, and the changeover relay switch is activated. 42, and the changeover relay switch 43 is connected to the power source, and the operation of the switch activates the illumination side ill d'i of the indicator lamp 4 and the ;1115 pressure stop control of the timer circuit 41.

1.1, the speed forward circuit is pulse circuit 45, relay switch -46 to <2, pulse circuit 45 sends a pulse to relay switch i4G by switching +if notation switching relay switch 42, ratchet 1 - step up A current is passed intermittently through the coil 1 () to create a rolled sheet 5.
Before i11. Then, the pulse transmission is stopped by operating the lesson start switch of the blade switch 290, and the movement of the roll sheet 5 is stopped.

The seat retraction circuit is a relay circuit 47 and a relay switch 48.
From this point on, the relay circuit 47 turns on the relay switch 48 by switching the changeover relay switch 42, and the ratchet claw release coil 19a and the motor 2 are turned on.
7, the roll sheet 5 is retracted, the zeblade switch 29Q turns ON, and then the relay switch 48 turns 0.
1 “Zaze, stop the movement of roll sheet 5.

The actual operation based on the above circuit configuration will be explained.

In the circuit shown in FIG. 8, the relay switches 42 and 43 in the lower stage are respectively 42a and 43a1, and the lower relay switches are 42b and 43b, respectively.

First, when the previous lesson is over and the seat is moved forward or backward at high speed and the lesson start switch, i.e. the blade switch 29g, is turned on, an OFF signal is sent to the pulse circuit 45 and relay circuit 47, and when the seat is moving forward at high speed. Then, the pulse transmission to the relay switch 46 is stopped, and the movement of the roll sheet 5 is stopped. Also, when the roll sheet 5 was moving backward, the race switch 48 is turned OFF, and the movement of the roll sheet 5 is also stopped.

When the timer start button 44 is pressed in this state, the next lesson starts.

That is, the timer circuit 41 operates and starts timing, and at the same time, the changeover relay switches 42 and 43 are operated to turn on the relay switch 42b143b. The display lamp 4 lights up when the relay switch 43b is turned on.

Then, the C operator reads TYP behind the characters displayed on display window 3.
Press the key corresponding to the letter indicated by the arrow as ERlls LIE ding ER.

11 When the 4th knee is pressed, the ratchet step-up coil 10 works and rolls the seat 1 by one step.
~5 is moved but the wrong key is pressed [,
L1 call sheet 5 does not move.

When the roll sheet 5 moves one step, the character of the next key to be pressed is indicated on the display window 3.

When the time set in the timer circuit 41 has elapsed by pressing the designated characters one after another in this way and before the lesson ends, the relay switch 42b is set to 01'.
F, 4? a is turned on, and the relay switch /
13b is turned off, the indicator lamp 4 disappears, and the relay switch 42a is turned on, thereby stopping the time counting operation of the timer circuit 41.

Even after the predetermined time has elapsed, the remaining key operations are continued, and when all key operations are completed, the blade switch 29h, which is the lesson end switch, is turned ON.]1
Since the relay switch 42a is in the ON state, an ON signal is transmitted to the relay circuit 41, which turns on the relay switch 48, and the ratchet pawl release coil 19 operates to remove the ratchet pawl 16 from the ratchet wheel 20. A current is roughly applied to the motor 27 to move the gear 28 attached to the drive shaft of the motor 27 to the sprocket 2.
4.25 is engaged with a gear 26 attached to a rotating shaft 21 and rotated, thereby retracting the roll sheet 5 to the right.

When the blade switch 29q detects the start position of the lesson you just practiced, it turns the relay switch 47 OFF.
When the signal is input, the relay switch 48 is turned off to stop the motor 27, the power to the ratchet pawl release coil 19 is cut off, the ratchet pawl 16 is engaged with the ratchet wheel 20 again, and the process ends.

Also, when all key operations in the lesson are completed within the time set in the timer circuit 41, the blade switch 29h, which is the lesson end switch, is turned on.
, since the relay switch 42b is still in the ON state,
5 ON signals are input to the pulse circuit 45 manually.

Therefore, a pulse is output from the pulse circuit 45 to the relay switch 46, causing the step-up coil 10 to be operated intermittently. [1-Rusheet 5woQ
A l'l'l JIL: 'a' t! Le.

Then, when the blade switch 29g detects the start position of the next lesson, the pulse circuit 45 changes to 0.
It will be done.

When the set time of the timer circuit 41 has elapsed, the changeover relay switches 42 and 43 switch the relay switches 42a,
43a is turned on, the display lamp 4 is turned on, and the timekeeping operation is stopped to complete the routine.

As mentioned above, if you do not finish the lesson within the timer setting time, the seat will be automatically returned to the original starting position and you will have to repeat the same lesson again to practice. Setting ++: If all the keys of Lusun can be operated to 1 [[, roll sheet 5]
will automatically advance to the start position of the next lesson, and
You can start practicing step by step.

There are various practice contents on the roll sheet 5, such as those that limit the fingers used for each lesson and those that change the number of key operations, so that the training can be practiced in stages according to the operator's skill level.
