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

FIG. 2 shows 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 in accordance with JIS standards, and above the keyboard 2, there is a display window 3 that is horizontally long on the left and right sides and displays key operation instructions. There is a message on the casing of Alumni 3 that says, ``Type this character.''
Or, the text "TYPE THIS LETTER" is printed with an arrow pointing to the letter to be typed.

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

The casing 1 of this machine is shaped like a rectangular parallelepiped, with a top cover 1a consisting of the top surface, front, rear, left and right sides, and a back cover 1b on the bottom. A sheet end roll 6a on which the sheet 5 is spirally wound is rotatably attached to the front and rear sides, and the rolled sheet 5 is on the left side.
A cylindrical storage portion 7b having a central axis in the front-rear direction and a sheet end roll 6b are provided to store the sheet.

The rolled sheet 5 wound around the sheet end roll 6a advances to the left through the gap between the substrate 8 and the key 9, and its tip enters through the slit-shaped opening 7c of the cylindrical storage section 7b, allowing it to rotate freely. The sheet is stored in the cylindrical storage portion 7b by the pivotally mounted sheet end roll 6b.

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

A relay mechanism suction plate 14 is installed on a right side facing the fixed iron core 11 on a hinge via a spring 15 perpendicular to the U-shaped fixing member 12, and when a current flows through the ratchet step-up coil 10, the suction plate 14 and turns off the current again, it returns to its original state.

A support shaft is installed in the groove provided in the upper central part of the suction plate 14 in the front-rear direction, and a ratchet pawl 16 is pivotably pivoted to the support shaft, and the ratchet pawl 16 is supported by a leaf spring 17. Therefore, in FIG. 5, the force is always applied in the counterclockwise direction. Also, ratchet claw 1
A fixed iron core 18 and a ratchet claw release coil 19 are fixed to the U-shaped fixing member 12 below the U-shaped fixing member 12 by winding the fixed iron core 18 around the center axis in the vertical direction.

A ratchet wheel 20 meshing with the ratchet pawl 16 is integrally provided on a rotating shaft 21, and the rotating shaft 21 is supported by supporting members 22 and 23 arranged at the front and rear ends and fixed to the base plate 8. It is pivoted so that it can rotate freely.

Further, a pair of sprockets 24 and 25 are integrally attached to the rotating shaft 21 near both ends, and a gear 26 is integrally attached to the center part, and the sprockets 24 and 25 are provided near both ends of the roll sheet 5 at equal intervals. The roll sheet 5 is moved by engaging with the hole.

Also, in front of the ratchet mechanism is a motor 27.
is attached to the substrate 8, and a gear 28 is integrally provided at the tip of the drive shaft. When current flows through the motor 27, the gear 28 pops out together with the drive shaft and connects with the rotation shaft 21. It meshes with the integrally attached gear 26, and the sprockets 24, 2
5 can be rotated clockwise in FIG. 4 to retract the rolled sheet 5, and when the current to the motor 27 is cut off, the gear 28 is retracted and separated from the gear 26.

This machine has the sheet moving mechanism as described above, and when moving the roll sheet 5 forward,
When 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 tooth of the ratchet wheel 20, and when the current is turned off, the suction plate 14 is attracted to the left (see Figure 5). When the spring 15 returns to its original position, the ratchet pawl 16
pushes the teeth to the right and rotates the ratchet wheel 20 one pitch counterclockwise, causing the sprockets 24 and 2 to rotate together with the ratchet wheel 20.
5, the roll sheet 5 is moved a certain distance to the left.

Therefore, the ratchet step-up coil 1
By intermittently passing a current through the roll sheet 5, the roll sheet 5 is gradually moved forward.

When the roll sheet 5 is moved backward, current is continuously applied to the ratchet claw release coil 19 and the motor 27.
When the motor 27 operates, the ratchet pawl 16 is sucked downward, and the ratchet pawl 16 and the ratchet wheel 20 are disengaged from each other, and almost at the same time, the motor 27
As a result, the gear 28 at the tip of the drive shaft and the gear 26 of the rotary shaft 21 mesh and rotate, and the sprockets 24 and 25 can continuously move the roll sheet 5 backward.

Eight blade switches 29a to 29h are arranged in parallel to the right side of the rotating shaft 21 in the sheet moving mechanism, and are fixed to the substrate 8, and from each blade switch 29a to 29h are contact pieces 30a to 29h. 30h protrudes to the left, and the contact pieces 30a to 30h are bent in a dogleg shape so that the contact portions protrude upward from slit-shaped grooves 31 provided in the substrate 8 (Fig. 4). reference).

When the groove 31 is closed by the roll sheet 5 and the contact portion of the contact piece is pressed down from above, the blade switch is in the OFF state,
When the hole provided in the roll sheet 5 fits into the groove 31 and the contact portion protrudes above the hole and contacts the printed portion of the mylar sheet above, the blade switch is turned on.

Inside the machine, a dry battery 32 is installed between the sheet moving mechanism and the delivery roll 6.

Next, the switching mechanism using the key 9 will be explained based on FIG. 6.

The key 9 consists of a push button 33, a support member 34, and a compression spring 35 interposed therebetween, and the support member 34 is fixed to a fixing member 36 provided above the base plate 8 with a gap therebetween.

A printed circuit board PCB 37 is bonded to the upper surface of the board 8, and a circuit is printed on the surface thereof.

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

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

Therefore, when the roll sheet 5 moves and comes under a key with a hole provided at a predetermined position in the roll sheet 5, and the push button 33 of the key is pressed, the tip of the push button 33 will be pressed. Push down the sheet 38 and bring it into contact with the PCB 37. Then, the wiring of the hot side circuit of the Mylar sheet 38 and the switch contact on the PCB 37 are electrically connected, and the switch of the key is turned on.

If there is no hole in the roll sheet 5 below the push button 33, the roll sheet 5 will block the Mylar sheet 38 even if the push button 33 is pressed.
There is no contact between the switch 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 to prevent the tip of the push button 33 from getting caught in the hole in the roll sheet 5, thereby preventing the movement of the roll sheet 5 from being obstructed. This is to ensure smooth movement.

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

The keyboard layout on the keyboard 2 is based on the JIS standard, and there are 5 lines (“1”) including the space key.
line, “Q” line, “A” line, “Z” line, “Space”
row).

Since the roll sheet 5 is intermittently moved forward to the left, "1" corresponding to the key arrangement of the 5 rows is pressed.
ROW LINE, “Q”ROW LINE, “A”ROW
LINE, “Z”ROW LINE, SPEACE KEY
A hole is provided at a predetermined position on each key switch line of LINE (see Figure 7).

In addition, the keys 9 on the keyboard 2 are classified into 6 groups, and the standard for this classification is that keys that are rarely pressed incorrectly, that is, keys that are located far apart, are grouped together.Group 1
The keys belonging to group 2 are 1, 7, E, 0, G, Z, M, and the keys belonging to group 2 are 2, 8, R, P, H,
X,, the keys belonging to group 3 are 3, 9, T,
A, J, C,. , the keys belonging to group 4 are 4,
0, Y, S, K, V, /, keys belonging to group 5 are 5, Q, U, D, L, B, keys belonging to group 6 are 6, W, I, F, :, N, space Keys shall not belong to these groups.

When a certain key is to be pressed, a group for that key is automatically specified in advance, and for keys for which no group is specified, no matter how many holes are provided in the roll sheet 5. Even if that 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, even within the same group, 2
There is a possibility that the above keys coincide with the holes provided in the roll sheet 5, and even in that case, the keys in the same group are located far apart from each other, so it is extremely rare for the keys to be pressed incorrectly. This makes it possible to extremely reduce the probability that an incorrect key operation will be judged as correct.

This group designation is made using the blade switch 29.
The switching is performed by six blade switches 29a to 29f among a to 29h, and the switching of these blade switches is performed by holes on the group switch line provided in the roll sheet 5. between the key switch lines
Grp.1SW LINE, Grp.2SW LINE, Grp.3SW
LINE, Grp.4SW LINE, Grp.5SW LINE,
There are six group switch lines of Grp.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.
The blade switches 29g and 29h are provided on the LESSON START POSITION SW LINE and the LESSON END POSITION SW LINE, and the switches for their detection are the blade switches 29g and 29h.

Note that the hole that engages with the teeth of the sprockets 24 and 25 for moving the seat 5 is the hole "1".
Above ROW LINE and SPACE KEY LINE
They are listed at a certain pitch below the .

The distance between adjacent left and right keys is 19.05 mm, and 3.175 mm, which is obtained by dividing this distance into six equal parts, is defined as the amount of movement of one step, that is, the amount of unit movement of the roll sheet 5 by the sprockets 24 and 25.

The characters of the key to be pressed, the lesson number, etc. are printed on the upper part of the roll sheet 5, and are displayed on the display window 3 on the upper surface of the casing.

The example shown in the roll sheet 5 shown in FIG. 7 is an example in which the keys used for practicing the left and right index fingers are all concentrated in the center of the keyboard.
JHFG RTUY The keys are operated in the order of JHFG RTUY.

There is a slit-shaped groove 31 provided in the substrate 8 at the position indicated by the vertical broken line in FIG. 7, and the contact portions of the contact pieces 30a to 30h protruding from the blade switches 29a to 29h are located therein. shall be.

Then, at this point, GRP.3SW of roll sheet 5
There is a hole at the intersection of LINE and the broken line, so when the blade switch 29c is in the ON state and group 3 is specified, at this time the roll sheet position below the J key ("A" ROW LINE
There is also a hole (at the position marked J above), 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 below the key, or even if there is a hole, it does not belong to group 3.

Note that this “J” is the first letter of LESSON1, so it is connected to the broken line and the LESSON on the sheet.
START POSITION SW There is also a hole where it intersects with LINE, and the switch weighs 28g.
is ON, and it is detected that the roll sheet 5 is at the start position.

Here, when the J key is pressed correctly, the rolled sheet 5 advances one pitch to the left, and when the wrong 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,
In Figure 7, it is the same as moving the broken line one pitch to the right, so this time, the broken line after the movement is
A hole is drilled at the position marked H where it intersects with Grp.2SW LINE, and group 2 is designated.
Roll sheet position below H key (“A” ROW
There is also a hole in the position marked with the symbol H on LINE, so pressing the H key indicates that the key has been pressed correctly.

In this way, for each character shown in the example, 2
This means that two holes are drilled at predetermined positions on the roll sheet.

Note that the space key is controlled by one hole.

Furthermore, in FIG. 7, the characters marked with "'" indicate the positions of the holes in the repeated portion, which is the latter half of the example problem.

Next, the switching circuit and the driving circuit for the coils 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 shows a switching circuit using key operations and blade switches 28a to 28h, and includes a group of switches that are turned on when a hole provided in the roll sheet 5 matches a key operation, and a predetermined switch on the roll sheet 5. It shows the switches that are turned on when the blade switches 29a to 29h are operated by holes provided at the positions.

The upper wire of each key switch is connected to the high potential side (hot side) of the power supply 40, the lower wire is connected to one contact of the blade switch of each group, and the other contact of the same blade switch is all connected. It is connected to the ratchet step-up coil 10.

Therefore, only when one of the key switches in the group in which the boolean switch is turned on, current flows through the ratchet step-up coil 10 and the sheet can be moved one step.

The space key switch is special, and if it is turned on, the ratchet step-up coil can be operated regardless of the blade switch.

Other circuits that control the movement of the rolled sheet 5 can be roughly divided into three types: a timer control circuit, a high-speed sheet advance circuit, and a sheet retract 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 also switches the changeover relay switch. 42 and 43, one contact of the changeover relay switch 42 is connected to a blade switch 29h which is a lesson end switch, and the changeover relay switch 43 is connected to the power supply, and the switch operation controls the lighting of the indicator lamp 4 and the timer circuit. 4
1 timing stop control is performed.

The high-speed sheet advance circuit consists of a pulse circuit 45 and a relay switch 46, and the pulse circuit 45 sends a pulse to the relay switch 46 by switching the changeover relay switch 42, and intermittently causes current to flow through the latching step-up coil 10. Advance the roll sheet 5 and press the blade switch 29g.
The pulse transmission is stopped by the operation of the lesson start switch, and the movement of the roll sheet 5 is stopped.

The sheet retraction circuit consists of a relay circuit 47 and a relay switch 48, and the relay circuit 47 turns on the relay switch 48 by switching the changeover relay switch 42, causing current to flow through the ratchet pawl release coil 19 and the motor 27 to release the roll sheet 5. When the roll sheet 5 is moved backward and the blade switch 29g is turned on, the relay switch 48 is turned off to stop the movement of the roll sheet 5.

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

Here, changeover relay switch 4 is connected using the circuit shown in Figure 8.
At 2 and 43, set the upper relay switch to 4 each.
2a, 43a, lower relay switch 42 each
b, 43b.

First, when the previous lesson is finished and the seat is moved forward or backward at high speed and the lesson start switch, that is, the blade switch 29g is turned on, an OFF signal is sent to the pulse circuit 45 and the relay circuit 47, and if the seat was moving forward at high speed, the relay switch is turned on. 4
6 is stopped, and the movement of the roll sheet 5 is stopped. Also, if it was moving backward, the relay 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 4 are activated.
3 to operate relay switches 42b and 43b.
Turn it on. When the relay switch 43b is turned on, the indicator lamp 4 lights up.

The operator then presses the key corresponding to the character displayed on the display window 3, which is indicated by an arrow as TYPE THIS LETTER.

When the correct key is pressed, the ratchet step-up coil 10 operates and the roll sheet 5 is moved by one step, but when the wrong key is pressed, the roll sheet 5 is not moved.

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 designated characters are pressed in sequence in this manner and the time set in the timer circuit 41 elapses before one lesson is completed, the relay switch 42b is turned OFF and the relay switch 42a is turned ON.
Further, the relay switch 43b is turned off, the indicator lamp 4 is turned off, and the relay switch 42 is turned off.
When a is turned ON, the time counting operation of the timer circuit 41 is stopped.

The operator continues to operate the remaining keys even after the predetermined time has elapsed, and when all key operations are completed, the blade switch 29h, which is the lesson end switch, is activated.
is ON, and since the relay switch 42a is in the ON state, an ON signal is transmitted to the relay circuit 47, and the relay switch 48 is turned ON by the same circuit 47.
Then, the ratchet claw release coil 19 operates to remove the ratchet claw 16 from the ratchet wheel 20, and current is applied to the motor 27 to release the motor 2.
By meshing and rotating the gear 28 attached to the drive shaft 7 with the gear 26 attached to the rotating shaft 21 integral with the sprockets 24 and 25, the roll sheet 5 is retreated to the right.

When the blade switch 29g detects the start position of the lesson you just practiced, an OFF signal is input to the relay switch 47, which turns off the relay switch 48 to stop the motor 27 and cut off the power to the ratchet claw release coil 19, thereby starting the ratchet. The pawl 16 is engaged with the ratchet wheel 20 again to complete the process.

Furthermore, when all key operations for one 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, and since the relay switch 42b is still in the ON state, the pulse circuit 45 is turned on. ON
A signal is input.

Therefore, a pulse signal is outputted from the pulse circuit 45 to the relay switch 46, which intermittently operates the ratchet step-up coil 10 to advance the roll sheet 5 at high speed.

When the blade switch 29g detects the start position of the next lesson, the pulse circuit 45
When the OFF signal is input, pulse transmission is stopped and the roll sheet 5 is stopped.

When the set time in the timer circuit 41 has elapsed, the switching relay switches 42 and 43 switch the relay switches 42a and 43a to the ON state.
The display lamp 4 is turned off and the timing operation is stopped to complete one lesson.

If you do not finish one lesson within the timer setting time as above, the sheet will be automatically returned to the original starting position and you will have to practice the same lesson again and again to become familiar with the lesson. When all the keys for one lesson can be operated correctly within the set time, the roll sheet 5 automatically advances to the start position of the next lesson, and the next level of training can begin.

The training contents on the roll sheet 5 include various exercises 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.

The size of the keyboard of the training machine in this embodiment is a standard size, and as a whole it is slightly wider than the keyboard in front, back, left and right, and the thickness is not so large, so it can be designed compactly.

In addition, a large number of example problems are recorded in stages according to the level of proficiency on one roll sheet 5, but if one sheet is not enough, it is possible to prepare another sheet and replace it. be. Roll sheet 5
is previously wound around the sheet end roll 6a and stored in the cylindrical storage section 7a, and the back cover 1b can be removed to replace the entire cylindrical storage section 7a.

The content recorded on the roll sheet 5 is not only for key operation practice, but also for learning purposes such as memorizing correct spelling and grammar of foreign languages such as English, so this device can be used as a teaching material. You can also do that.

In this embodiment, the rolled sheet 5 wound around the sheet terminal roll 6a is used, but it is also possible to use a card insertion method and make the keyboard smaller than the standard size to make it even more compact and convenient to carry. are shown in FIGS. 9 and 10.

Instead of the rolled sheet in the previous embodiment, in this embodiment, one card 52 is prepared for each lesson as shown in FIG.
It is designed to be used by inserting it into the device.

In FIG. 9, the main body 50 of this training machine is the upper part, and the lower part is a card storage box 51 in which a plurality of the cards 52 can be stored.

The card 52 is used by inserting the card 52 through a slit-shaped groove 53 provided on the right side of the main body 50.

The function as a training aircraft is almost the same as that of the previous embodiment.

Since the keyboard is designed to be smaller than the standard size, the individual keys themselves are also small, and various shapes of keys have been considered as shown in FIG.

In addition to printing or engraving the name of the key on the surface of each key, the name may be attached to the casing as shown in FIG. 11.

Another possibility is to attach another sheet with the name of the key printed on it to the surface of the key or to the casing near the key.By doing this, you can easily change the name of the key, for example in Japanese. It can also be used as a training machine for word processors, etc.

Further, in the above embodiment, the setting time of the timer is fixed, but it may be possible to make the setting time more convenient by allowing the user to set it freely. It can also be seen as a competition machine that competes with others.

It is also conceivable to use one stepping motor and drive and control the motor so that the rolled sheet or card can be moved both forward and backward.

Furthermore, in the above embodiments, holes were provided in the roll sheet or card as electrically conductive parts, but
A contact point may simply be made of a conductive substance.

Effects of the Invention The present invention is a small typewriting practice machine that is convenient to carry and can be practiced anytime and anywhere, allowing for early improvement.

Also, by setting a fixed time, you can objectively gauge your own key operation proficiency, and you can always practice at an appropriate difficulty level, allowing you to master techniques step by step.

In addition to typing in English, you can also practice key operations on Japanese word processors, computers, etc.

Furthermore, by simply replacing the sheet for recording practice content, it can be used as a learning material for foreign languages, and it can also be used as a game machine in which operators compete in terms of key operation speed, etc.
