<Embodiment> Next, an embodiment of the present invention in which the above means is applied to an electronic typewriter will be described.

[First example]

In this embodiment, a ribbon adapter, a ribbon cassette in which the ribbon adapter is loaded, and a recording device in which the ribbon cassette is loaded will be explained in this order.

Figure 1 shows ribbon adapter A and ribbon skein.

FIG. 2(a) is a perspective explanatory view of ribbon adapter A.
FIG. 2(b) is an exploded explanatory view of the ribbon supplying section of FIG.

(ribbon adapter) First, the configuration of the ribbon adapter A will be explained.

(General description) In this ribbon adapter A, as shown in FIGS. 1 and 2, the correction ribbon 1 is wound from the supply means 2 to the winding means 3, and both means 2 and 3 are rotatable around the support frame 4. is attached to. Further, this ribbon adapter A is formed with a ribbon feeding means 5, and is configured such that by operating this feeding means 5, the corrected ribbon I is pulled out from the supplying means 2 and wound onto the winding means 3.

Further, the support frame 4 is formed with adapter locking means 6 for loading the ribbon adapter 8 into a ribbon cassette B to be described later.

Next, the configuration of each part of the ribbon adapter A will be specifically explained.

(Feeding Means) The feeding means 2 is for feeding out the wound correction ribbon 1, and as shown in FIG. 2(a), a spool support member 2a is rotatably attached to a spool shaft 4a of a support frame 4. A supply spool 2b with the correction ribbon 1 wound thereon is attached to the spool support member 2a.

The spool support member 2a has a base portion 2a on one side of a collar portion 2a+, and a spool locking portion 2a3 is formed protrudingly on the other side. A locking protrusion 2a< is provided in a protruding manner on the spool locking portion 2as, and when the supply spool 2b is fitted into the spool locking portion 2as, the locking protrusion 2b+ formed on the spool 2b engages with the locking protrusion 2aa. The spool support member 2a and the supply spool 2b are configured to rotate integrally. In addition, the spool locking portion 2a
3 is formed with a locking protrusion 2as to prevent the fitted supply spool 2b from falling off from the spool locking portion 2a3.

The spool support member 2a is rotatably attached to the spool shaft 4a, and a stop ring 2C is attached to the tip of the shaft 4a to prevent it from falling off the shaft 4a.

Further, a torsion coil 2d similar to a one-way clutch is attached to the base 2az of the spool support member 2a, and a tension spring 2e is attached to one end 2d of the coil 2d.
One end of the spring 2e is locked, and the other end of the spring 2e is locked to a locking protrusion 4b of the support frame 4.

The spool support member 2a of the family coil 2d is arranged in the direction of arrow a in FIG.
When the base 2az is rotated in the direction in which the base 2az is fed out, the base 2az is tightened, and when the base 2az is rotated in the opposite direction, the tightening is released. Therefore, when the spool support member 2a rotates in the direction of arrow a when drawing out the ribbon, the coil 2d rotates integrally with the spool support member 2a, and the tension spring 2e tensions it along the circumferential surface of the base 2az.

When the spool support member 2a further rotates, the free end 2d2 of the coil 2d comes into contact with the locking protrusion 4b, and the rotation of the coil 2d is restricted. Therefore, when the correction ribbon 1 is paid out from the supply spool 2b, a predetermined tension is applied to the correction ribbon 1 by the tension of the tension spring 2c.

In addition, in FIG. 2(a), when the spring support member 2a rotates in the opposite direction to the arrow a, the coil end 2d comes into contact with the regulating protrusion 4C protruding from the support frame 4. This restricts the rotation of the coil 2d.

The correction ribbon 1 wound around the supply spool 2b has an adhesive layer formed on a long base film.
From the flanged guide roller 4dl attached to the support frame 4 shown in FIG. be guided by.

(Winding means and ribbon feeding means) The winding means is for winding up the corrected ribbon 1 pulled out from the supply means 2, and in this embodiment, the winding spool 3 is attached to the support frame 4. It is rotatably attached and configured so that the ribbon 1 is wound onto this take-up spool 3.

As shown in FIG. 2(b), the take-up spool 3 has flanges 3b and 3c formed on both sides of a ribbon winding portion 3a, and a take-up portion 3d formed on the outside of the flanges 3c. There is. Moreover, a sawtooth part 3e is formed inside the flange part 3b and engages with a sawtooth part 5a formed on the side surface of the wind turbine 5a. The take-up spool 3 is rotatably attached to a spool shaft 4e projecting from the support frame 4 with the windmill 5a and the feed lever 5b interposed therebetween.

The windmill 5a is also rotatably attached to the spool shaft 4e. A claw portion 5az is formed on the circumference of the windmill 5a, and a feed claw portion 5b of a feed lever 5b meshes with the claw portion 5az to form a so-called ratchet mechanism. This ratchet mechanism is such that when the feed lever 5b rotatably attached to the spool shaft 4e is rotated in the direction indicated by the arrow in FIG.
z and rotates the windmill 5a in the direction of arrow C. At this time, the take-up spool 3 with which the sawtooth portions 3e and 5a are engaged also rotates integrally. When the feed lever 5b rotates in the direction of the arrow d as shown in FIG. 3(a), the feed claw portion 5b does not engage with the claw portion 5bz, and the windmill 5b is configured not to rotate.

A locking protrusion 5b is provided protrudingly on the feed lever 5b,
A tension spring 5C is attached between this protrusion 5t++ and a hook portion 5g+ of a lock lever 5g to be described later, and the feed lever 5b is constantly pulled in the direction of arrow d in FIG. 3(a) by this spring 5c. .

Further, as shown in FIGS. 3(a) and 3(b), a reverse rotation prevention claw 5d is attached to the side surface of the support frame 4, and the reverse rotation prevention claw 5d is configured to mesh with the claw portion 5az of the wind turbine 5a. It is configured. When the windmill 5a rotates in the direction of arrow C in FIG.
However, when the wind turbine 5a tries to rotate in the opposite direction to the arrow C, it engages with the claw portion 5az and restricts the rotation of the wind turbine 5a.

Therefore, the feed lever 5b shown in FIGS. 3(a) and (bl)
By moving the lever part 5b2 up and down, the wind turbine 5a
is rotated in the direction of arrow C, the correction ribbon 1 can be pulled out from the supply spool 2b and taken up onto the take-up spool 3. In this embodiment, the correction cam 5e serving as the contact member is slid in the direction of the arrow e to bring the inclined cam surface 5e+ or flat portion 5e5 into contact with the lever part 5bz and push it up. In this state, by shifting the ribbon cassette B loaded with the ribbon adapter A in the direction of the arrow f in FIGS.
It is configured to move up and down.

(Drive structure of correction cam) Here, a drive structure for sliding the correction cam 5e will be explained.

This correction cam 5e is slidably mounted on a carriage to be described later, and as shown in 31st ffl(a), w), a rack 5e2 is formed in the side wall of the correction cam 5e. The rack 5ez is shown in FIG. 4(a).
As shown in (C), a cam gear 5e rotatable about a shaft 5ez meshes with the cam gear 5e, and the correction cam 5e is configured to be slidable on the carriage by rotation of the cam gear 5ea.

The driving force transmission to the cam gear 5e< is shown in Fig. 4 fa) to (
This is performed by a driving means 5f as shown in C). In this drive means 5f, an idler gear 5f4 that rotates around a shaft 5r3 provided on the carriage meshes with a pinion gear 5ft attached to the motor shaft of the ribbon motor 5L. An arm 5f is attached to the shaft 5k and is rotatably supported around the shaft 5f3. An idle gear 5ft rotating around a shaft 5fb is supported at the tip of the arm 5f5, and the idle gear 5rq meshes with the idler gear 5fa. The idle gear 5ft is attached to the arm 5f5 by a wave washer (not shown) so that some load is applied to the rotation thereof.

Therefore, when the idler gear 5f rotates, the idle gear 5f7 is configured to rotate around the idler gear 5r4 as the arm 5rs rotates while remaining in mesh with the idler gear 5fn. The idle gear 5ft is configured to mesh with the cam gear 5ea when the arm 5f rotates in the direction of arrow g, as shown in FIG. 4 (al).

Therefore, as shown in FIG. 4(a), with the idle gear 5f7 meshing with the cam gear 5ea, the ribbon motor 5r,
When the is driven in reverse (rotated in the direction of the arrow in FIG. 4(a)), the correction cam 5e moves in the direction of the arrow e, and as shown in FIG. 5b
2 is pushed up in the direction indicated by the arrow, and the correction ribbon 1 is wound onto the take-up spool 3. Further, when the ribbon adapter A is shifted up and down with the inclined cam surface 5e+ or the flat portion 5es in contact with the lever portion 5b2, the correction ribbon 1 is further wound onto the take-up spool 3. More specifically, by shifting the adapter A downward, the lever portion 5b2 is pushed up and the correction ribbon 1 is wound up. Furthermore, when shifting the adapter A upward, the lever part 5b is moved by a reversal prevention pawl 5d, etc., which will be described later.
Even if , returns, the correction ribbon 1 will not return.

In addition, as shown in No. 41m(a) to (C), the correction cam 5e
A tension spring 5fe is attached to. Therefore, as shown in FIG. 4(b), when the ribbon motor 5f1 is driven to rotate normally (rotated in the direction of arrow 1 in 411ffl(b)), the arm 5fs rotates in the direction of arrow j, and the idle gear 5
The meshing between r7 and cam gear 5ea is released, and the correction cam 5
e slides in the direction of the arrow and retreats by the tension spring 5fsO. At this time, the feed lever 5b is
As shown in Figure (a), the wind turbine 5a rotates in the direction of arrow d by the tension spring 5C, but the rotation of the wind turbine 5a is restricted by the anti-reverse claw 5d and does not rotate.

Further, as described above, when the arm 5r rotates in the direction of the arrow j, it is configured to mesh with the idler gear 5f and the lever gear 12, as shown in FIG. 4(C). This ribbon gear 12 is attached to a carriage and connected to a winding shaft for winding up an ink ribbon, which will be described later.

Therefore, by driving the ribbon motor 5r in normal rotation, the take-up shaft can be rotated and the ink ribbon can be taken up. This makes it possible to operate the correction cam 5e and wind up the ink ribbon with one motor.

(Locking means of ribbon adapter) Next, the lock lever 5g will be explained. This lock lever 5g is attached to the take-up spool 3 attached to the spool shaft 4e.
The lever shaft 41 is rotatably mounted on a lever shaft 41 protruding from the side surface of the support frame 4 shown in FIG. 41 so that it does not fall off.

This lock lever 5g includes a first lock portion 5gz and a second lock portion 5gi, as shown in FIGS. 2(b) and 5.

The first locking portion 5gz presses the side surface of the serrated portion 3e of the take-up spool 3 attached to the spool shaft 4e, and the second lock portion 5g3 presses the side surface of the flange portion 3b, and also holds the side surface of the serrated portion 3e of the take-up spool 3 attached to the spool shaft 4e. This is to hold down the correction ribbon 1. This restricts the movement of the take-up spool 3 attached to the spool shaft 4e in the thrust direction and locks the take-up spool 3 from falling off the spool shaft 4e.

When attaching the take-up spool 3 to the spool shaft 4e,
As shown in FIG. 6, hold the lever part 5gm and rotate it in the direction of arrow e to retract the locking parts 5gz, 5g3 from the take-up spool 3 and release the lock. At this time, the unlocked state is maintained in which the locking projection 5gs of the locking member 5g shown in FIG. 2(b) engages with the locking recess 5ba formed in the projection 5b3 of the feed lever 5b.

Then, after attaching the take-up spool 3 to the spool shaft 4e, rotate it in the direction opposite to the arrow 1 to release the engagement,
This locks the take-up spool 3 so that it does not fall off.

(Automatic locking structure) In this embodiment, when the ribbon adapter 8 is used with the locking member 5g in the unlocked state, the four hook members 5g are automatically locked.

The configuration for this purpose is to form a cut slope 5g6 at the corner of the lever part 5ga of the locking member 5g, as shown in the 7th article,
This slope 5g6 is configured to abut against the frame of the recording device in the unlocked state.

That is, as shown in FIG. 8(a), the ribbon adapter A is loaded into the ribbon cassette B with the locking member 5g unlocked, and this ribbon cassette B is loaded into the carriage 12b of the recording device C to make corrections. When the operation is performed, it is carried by the initial operation after the power is turned on.

When the gear 12b moves to the left end of the movement range, the slope 5g6
comes into contact with the sloped part 13a1 of the frame 13a and rides on the sloped part 13a, and the lock lever
5g receives a rotating force in the direction of arrow m in FIG. 8(a).

Due to the force in the direction of the arrow m, the locking protrusion 5gs and the locking recess 5b4 (Fig. 2
) is forcibly disengaged, and as shown in FIG. 8(b), the opening 5g automatically closes under the bias of the tension spring 5C.

Therefore, even if the opening/closing lever 5g is in the unlocked state, it will be automatically locked by initial operation of the carriage I2b.

(Support Frame and Adapter Locking Means) As shown in FIG. 1, the support frame 4 has spool supports 4g and 4h integrally formed at both ends of a connecting portion 4f, and a supply spool 2b on one support 4g. is attached, and the take-up spool 3 is attached to the other support 4h. and from the supply spool 2b to the take-up spool 3.
The correction ribbon 1 pulled out by the guide roller 462. 4
A cent is drawn as if it were stretched between d3.

is provided. This adapter locking means 6 has locking hooks 6a protruding from the supports 4g and 4h, and is configured such that the hooks 6a lock into locking recesses of a ribbon cassette B, which will be described later.

Further, a holding plate 6b is formed on the upper part of the holder a when the ribbon adapter A is loaded into the ribbon cassette B. Furthermore, an insertion plate 6c is formed at the upper front surface of the supports 4g and 4h.

(ribbon cassette) Next, the ribbon cassette B will be explained.

(Cassette Main Body) As shown in FIG. 1, this ribbon cassette B stores an ink ribbon 7, and has arm portions 8a and 8b protruding from both sides of a cassette case 8. A supply core 8C and a take-up core 8d are rotatably housed in this case 8,
An ink ribbon 7 is wound around both cores 8c and 8d.

The ink ribbon 7 is a long support film coated with ink, and the ink ribbon 7 pulled out from the supply core 8C is exposed through the opening 8e at the tip of the arm 8a and attached to the tip of the arm. The winding core is guided by the guide surface 8f attached to the cassette case 8, and further guided by the guide surface 8g attached to the tip of the arm portion 8b on the other side, and returns to the cassette case 8 through the tip opening 8h of the arm portion 8b. It is housed so as to wrap around 8d.

(Adapter Loading Means) A locking recess 81 serving as an adapter loading means is formed on the outer surface of the tip of the arm portions 8a, 8b. When the aforementioned ribbon adapter A is loaded into the ribbon cassette B, the locking hook 6a for the ribbon adapter is locked into this locking recess 8, as shown in FIG.

When the ribbon adapter A is loaded into the ribbon cassette B by locking the locking hook 6a into the locking recess 81 as described above, the holding plate 6b and the connecting portion 4f of the ribbon adapter A clamp the upper and lower surfaces of the cassette case 8. Vertical rattling is prevented, and horizontal rattling is also prevented by inserting the insertion plate 6c into the openings 8e and 8h at the ends of the arms 8a and 8b and pressing the outer walls of the openings. Therefore, the ribbon adapter A can be loaded into the ribbon cassette B without wobbling.

Here, in the ribbon cassette B, since the ink ribbon 7 is stretched and exposed between the guide surfaces 8f and 8g, the ink ribbon 7 in this part is easily damaged, and the ink ribbon 7 in this part is easily damaged. may come into contact with other objects and cause ink stains.

Therefore, in this embodiment, as shown in FIG. 10, a protective cover 9 is configured to be attached to the tip of the arm portion of the ribbon cassette B. When the cover 9 is attached to the tip of the arm, the protrusion 9a fits and locks into the locking recess 81 of the ribbon cassette B. Therefore, when the ribbon cassette B is not used, the protective cover 9
By attaching it to the tip of the arm to cover the exposed ink ribbon 7, the ink ribbon 7 will not be damaged and ink stains can be prevented.

As mentioned above, in the ribbon cassette B in this embodiment, the locking recesses 8 formed at the tips of the arm portions 8a and 8b are
1, the ribbon adapter A can be loaded and the protective cover 9 can also be attached.

(Engagement Means) The ribbon cassette B can be loaded into a recording device C to be described later, and for this purpose, locking protrusions 8j, which serve as engagement means, are protrudingly provided on both sides of the cassette case 8 substantially in the center.

(Recording Apparatus) Next, the configuration of a recording apparatus that performs recording by loading the ribbon force set B will be described.

During recording, the recording means 12 moves the carriage 12b to the recording position, rotates the type wheel 12g, and brings desired type to face the hammer 12i.
21 is driven to strike the back surface of the type, thereby transferring ink from the ink ribbon 7 onto the recording sheet 11 to perform printing. When the minus character is printed in this way, the carriage 12b moves to the next printing position and performs the next printing. When the negative line printing is completed, the recording sheet 1 is conveyed by one line by the sheet conveying means 10, and the next line is printed in the same manner.

(Sheet Conveying Means) The sheet conveying means 10 feeds the recording sheet 11 to a recording position and also discharges the sheet 11 after recording.

Next, the control procedure when loading the ribbon adapter A into the ribbon cassette B and loading this ribbon force set B into the recording bag WC for printing and correction is shown in FIG. 16(a).
) to (C) will be explained with reference to the flowcharts.

FIG. 16(a) is a flowchart showing the initial operation of the recording apparatus C. First, when the power is turned on in step S1, the process moves to steps 32 to S4, where the carriage motor 12e is driven until the carriage sensor 18 is turned on, and the carriage 12b is moved to the left end in FIG. 11. With this, the lock lever 5g of ribbon adapter A
Even if it is in the unlocked state, it will be automatically locked as described above.

Next, in step S5, the soft motor 14g is driven by a certain amount to move the cassette table 14a downward, and in step S6, the ribbon motor 5fl is rotated forward by a certain amount to wind up the ink ribbon 7 by a certain amount. Further, the process moves to steps 57 to S9, and the wheel motor 12f is driven until the wheel sensor 19 is turned on, so that the home position of the type wheel 12g is opposed to the hammer 12i. Then, in step S10, the carriage motor 12e is driven by a certain amount, and the carriage 12b is moved from the left end to the right by a certain amount to the recording reference position.

This results in a recording standby state.

Next, the printing operation and the operation procedure for correcting incorrect printing are shown in Figure 16 (b).
This will be explained with reference to the flowchart. It should be noted that the printing procedure shown in this flowchart is for one character printing.

When a print or correction signal or other processing signal is input in the recording standby state as described above, the signal is determined in step Sll, and if printing is to be performed, the process moves to step 512 and correction is performed. If so, the process moves to step S20, and if other processing is to be performed, the process moves to step S37.

If the printing signal is input in step Sll, the process moves to step 512, and the wheel motor 12f is driven to drive the desired type on the type wheel 12g with the hammer 12i.
to face. Next, step S13. Proceeding to S14, the shift motor 14g is driven to shift the cassette table 14a upward and shift the ink ribbon 7 to a position facing the selected type.

Next, the process moves to step 515, where the ribbon motor 5f1 is driven in normal rotation to wind up a predetermined amount of the ink ribbon 7, and in step 316, the hammer solenoid 12h is driven to hit the selected type with the hammer 124, thereby inking the ink. The ink on the ribbon 7 is transferred to the recording sheet 11 and printed. After printing, the process moves to steps 317 to S19, where the cassette table 14a is shifted down, and
Move the carriage 12b to the next printing position and proceed to step S.
Return to ll and wait for the next print command.

Further, if a correction signal has been input in step Sll, the process moves to step S20 and the wheel motor 12f
is driven so that the printed character to be corrected faces the hammer 121, and in step S21, the carriage motor 12e is driven so that the carriage 12b moves to the corrected character position. Then, the process moves to step 522S23, and the shift motor 14g is driven so that the correction ribbon 1 faces the selected type (■ in FIG. 13(a) is the hammer 1).

Next, step S24. Proceeding to S25, the ribbon motor 5f1 is reversely driven to project the correction cam 5e in the direction of the arrow e as shown in FIG. , sends out a fixed amount of modified ribbon.

Next, proceeding to step S26, the hammer solenoid 12
i is driven to hit the correction ribbon 1 with the selected character to perform a correction impact action. As a result, the erroneous printing ink sticks to the correction ribbon 1 and is peeled off from the recording sheet 11. In this embodiment, after hitting the erroneously printed area with the correction ribbon 1 as described above, the shift motor 14g is driven forward and backward as shown in steps 327 to S32 to move the cassette 7) to the table 1.
4a is moved up and down to feed out a fixed amount of the correction ribbon 1, the carriage motor 12e is driven to slightly move the carriage 12b, and the correction impact operation of hitting with the hammer 12i is repeated two more times. As a result, the recording sheet 11
The erroneous printing ink printed on the sheet 11 is completely peeled off from the sheet 11.

After stripping the erroneously printed ink from the recording sheet 11 as described above, in step S33, the ribbon motor 5
The correction cam 5e is returned to the standby position by normal rotation of the cassette table 14a in steps S34 to S36.
At the same time, the carriage 12b is returned to the standby position where printing can be performed at the corrected character position.

Further, in step Sll, if a processing signal other than the above-described print signal or correction signal, such as a sheet conveyance signal, is input, the process moves to step 337 and the processing corresponding to the processing signal is performed. Note that the note transport procedure and the like are well known and will not be described here.

Next, the printing procedure when the printing signal is continuous printing will be explained with reference to the flowchart shown in FIG. 16(C).

When the print signal is input as described above in step S42, it is determined in step S43 which position on the ink ribbon 7 the printing position is. Then, among the printing positions of ■ to ■ in FIG. 13(b), when the print positions are ■ and ■, the process jumps to step 558, when the print positions are ■ and ■, the process jumps to step S52, and when the print positions are ■ and ■, the process jumps to step S44. Move to.

For example, if the printing position is the position marked ■ shown in FIG. 13(b), the shift motor 14g is driven in step S44 to shift the cassette table 14a to the position marked ■ so that printing is possible. Amplify. As a result, the position where the hammer 121 faces in FIG.

Next, step S45. Proceeding to S46, the type wheel 12g is rotated to make the desired type face the hammer 12i, and the type is struck by the hammer 12i to print.

After the printing is completed, it is determined in step S47 whether there is any next printing, and if there is no next printing, the process returns to step S41 and the cassette table 14a is shifted down to the standby position. On the other hand, if there is next printing, step 348. S
49, the cassette table 14a is shifted by one character. As a result, the position where the hammer 12i opposes in FIG. Shift down by one character with 34B so that the position of ■ faces the hammer 12i).

Carriage 1 in step S50 to S53

The printed characters are faced to each other and are struck with the hammer 12i to print.

Next, in step S54, it is determined whether or not there is next printing, and if recording has ended, the process returns to step S41, and if there is next printing, step S55. The process moves to S56 and the carriage 12b is moved to the next printing position. and step S5
At step 7, the ribbon motor 5f+ is driven in normal rotation to wind up the ink ribbon 7 for one character. As a result, hammer 12
The position of the ink ribbon 7 facing i is the position marked ■ in FIG. 13(b) (the position printed in step S53 is the first
When it is in the position of ■ in Figure 3 (b), it is in the position of ■.)

And step S58. The process moves to S59, where desired characters are selected and printed.

Furthermore, if there is a next print in step S60, step S61. Moving to S62, the cassette table 14a
Shift up one character. This results in Figure 13 (a
), the position facing the hammer 12i becomes the position marked ■ on the ink ribbon 7 (if the position printed in step S46 is the position marked ■ in FIG. 13(b), it is shifted by one character in step S48). Down and hammer 1 at ■ position
2i).

Next, in steps S63 and S64, the carriage 12b is moved to the next printing position, and the process returns to step S45.

Shift the cassette table 14a as described above and
As shown in Figure (b), three characters are printed in each width direction of the ink ribbon 7.

Printing is performed on the recording sheet 11 as described above, and the printing can be corrected by loading the ribbon adapter A into the ribbon cassette B and erasing the printing as described above.

The ribbon adapter A can be easily loaded into the ribbon cassette B. Even if the ribbon adapter A is loaded into the ribbon cassette B in the unlocked state, it can be automatically lengthened by initial operation of the carriage 12b, and the ribbon motor 5f+ for winding up the ink ribbon 7 can automatically lengthen the ribbon. It is possible to operate the correction cam 5e that sends out 1.
