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

Figure 1 is a perspective explanatory view of ribbon adapter A and ribbon cassette B, Figure 2 (a) is an exploded explanatory view of the ribbon supply section to the ribbon adapter, and Figure 25 (b) is the ribbon winding section to the ribbon adapter. and FIG. 7 is an exploded explanatory view of parts of the ribbon feeding mechanism.

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

(Overall description) As shown in FIGS. 1 and 2, the second ribbon adapter A has a modified ribbon 1 wound around a winding means 3 from a supply means 2, and both means 2 and 3 are rotated around a support frame 4. Possibly installed. Further, this ribbon adapter A is formed with a ribbon feeding means 5, and is configured such that the corrected ribbon 1 is pulled out from the supplying means 2 and wound onto the winding means 3 by operating this feeding means 5.

Further, the support frame 4 is formed with an adapter locking means 6 for loading the ribbon adapter A into a ribbon cassette B, which will 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 2az on one side of the flange portion 2a+, and a spool locking portion 2a3 is formed protrudingly on the other side. A locking protrusion 2aa is provided in a protruding manner on the spool locking part 2ay, and when the supply spool 2b is fitted into the spool locking part 2a3, the locking protrusion 2b formed on the spool 2b engages 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
A locking protrusion 2as is formed on y so that the fitted supply spool 2b does not fall off from the spool locking portion 2az.

The spool support member 2a is rotatably attached to the spool shaft 4a, and a stomp 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 side 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 torsion coil 2d has a spool support member 2a in the direction of arrow a in FIG.
When the base 2a2 is rotated in the direction in which the base 2a2 is fed out, the base 2a2 is tightened, and when the base 2a2 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 2dz 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 2e.

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, and the coil This restricts the rotation of 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 4d1 attached to the support frame 4 shown in (b), via the guide roller 4dz, and further from the guide roller 4ds to the flanged guide roller dcL, to the take-up spool 3, which serves as the winding means. be guided as follows.

(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. Further, a sawtooth portion 3e is formed inside the flange portion 3b and engages with a sawtooth portion 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. In this ratchet mechanism, when the feed lever 5b rotatably attached to the spool shaft 4e is rotated in the direction indicated by the arrow in FIG.
2 to rotate 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 5bs is provided protrudingly on the feed lever 5b,
A tension spring 5c is attached between this protrusion 5b3 and a hook portion 5g+ of a lock lever 5g, which will 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. .

Furthermore, 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 second reverse rotation prevention claw 5d engages with the claw portion 5az of the model wheel 5a. It is configured as follows. When the mold wheel 5a rotates in the direction of arrow C in FIG.
However, when the mold wheel 5a attempts to rotate in the opposite direction to the arrow C, it engages with the pawl portion 5az and restricts the rotation of the mold wheel 5a.

Therefore, the feed lever 5b shown in FIGS. 3(a) and 3(b)
By moving the lever part 5bz up and down, the model car 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, as shown in FIG. 3(b), the correction cam 5e serving as the abutting member is slid in the direction of the arrow e, and the inclined cam surface 5e+ or the flat portion 5e5 is attached to the lever portion 5b,
In this state, the ribbon cassette B loaded with the ribbon adapter A is shifted in the direction of the arrow f in FIG. It consists of

(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 FIGS. 3(a) and 3(b), racks 5t and 5z are formed on the sides of the correction cam 5e. And the above U, Ri 5ex is shown in Fig. 4(a)~
As shown in (C), it meshes with a cam gear 5e4 that is rotatable around a shaft 5ei, and the correction cam 5e is configured to be slidable on the carriage by rotation of the cam gear 5ea.

The driving force is transmitted to the cam gear 5ea as shown in FIGS. 4(a) to 4(a).
This is performed by a driving means 5f as shown in C). In this drive means 5f, an idler gear 5fa that rotates around a shaft 5fs provided on the carriage meshes with a pinion gear 5h attached to the motor shaft of the ribbon motor 5fl. An arm 5f is attached to the shaft 5rz and is rotatably supported around the shaft 5f3. An idle gear 5ft rotating around a shaft 5rb is supported at the tip of this arm 5fs, and this idle gear 5f
7 meshes with the idler gear 5f4. The idle gear 5ft is attached to the arm 5fs by a wave washer (not shown) so that some load is applied to the rotation.

Therefore, when the idler gear 5f rotates, the idle gear 5f is configured to rotate around the idler gear 5f as the arm 5fsO rotates while remaining in mesh with the idler gear 5f. The idle gear 5f is configured to mesh with the cam gear 5ea when the arm sf5 rotates in the direction of arrow g, as shown in FIG. 4(a).

Therefore, as shown in FIG. 4(al), with the idle gear 5r meshing with the cam gear 5ea, the ribbon motor 5f
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
The correction ribbon 1 is pushed up in the direction indicated by the arrow z, and the correction ribbon 1 is wound onto the take-up spool 3. Furthermore, 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 5bz, the corrected ribbon 1 is further wound onto the take-up spool 3. More specifically, by shifting the adapter A downward, the lever portion 5bz is pushed up and the correction ribbon 1 is wound up. In addition, when shifting the adapter A upward, the lever part 5b is moved by using a reversal prevention pawl 5d, etc., which will be described later.
Even if z returns, the correction ribbon 1 will not return.

Incidentally, as shown in FIGS. 4(a) to 4(C), a tension spring 5f is attached to the correction cam 5e. Therefore,
As shown in FIG. 4(b), when the ribbon motor 5r+ is driven forward (rotated in the direction of the arrow i of the fourth rotation), the arm 5rs rotates in the direction of the arrow j, and the idle gear 5f is rotated.

The meshing between the cam gear 5ea and the cam gear 5ea is released, and the correction cam 5e slides in the direction of the arrow by the tension spring 5fsO and retreats. At this time, the feed lever 5b is moved as shown in Fig. 3 (
As shown in a), the tension spring 5C rotates in the direction of arrow d, but the rotation of the mold wheel 5a is restricted by the anti-reverse claw 5d and does not rotate.

Further, as described above, when the arm 5fs rotates in the direction of the arrow j, the idle gear 5f7 is configured to mesh with the bong 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 5f1 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.
It constitutes a locking means to prevent the frame from falling off, and is rotatable 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 has a first lock portion 5gz and a second lock portion 5g+, as shown in FIGS. 2(b) and 5.

The first locking portion 5gg 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 collar portion 3b, and the winding spool 3 is wound up on the take-up spool 3. 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 Figure 6, hold the lever part 5ga and press the arrow! direction, the locking portions 5gz, 5g3 are retracted from the take-up spool 3 and unlocked. At this time, the unlocked state is maintained in which the locking protrusion 5gs of the locking member 5g engages with the locking recess 5b formed in the projection 5b of the feed lever 5b as shown in FIG. 2(b).

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 A is used with the locking member 5g in the unlocked state, the locking member 5g is automatically locked.

The configuration for this purpose is to form a cut slope 5gh at the corner of the lever part 5gm of the locking member 5g, as shown in FIG.
This slope 5gb is configured to abut against the frame of the recording device in the unlocked state.

That is, as shown in No. 81ffl(a), the locking member 5g
With the ribbon adapter A unlocked, load the ribbon adapter A into the ribbon cassette B, and insert this ribbon cassette B into the recording device C.
When the carriage 12b is loaded into the carriage 12b and a correction operation is performed, when the carriage 12b moves to the left end of the movement range due to the initial operation after the power is turned on, the slope 5g comes into contact with the slope 13a1 of the frame 13a, and the slope 13a1 touches the slope 13a1. The lock lever 5g will move as shown in Figure 8 (a).
It receives a rotational force in the direction of arrow m.

Due to the force in the direction of the arrow m, the engagement between the locking protrusion 5gs and the locking recess 5b4 (see Figure 2 °C), which maintains the unlocked state, is forcibly released, as shown in Figure 8 et al. The lock lever 5g is automatically locked by the bias of the tension spring 5c.

Therefore, even if the lock lever 5g is in the unlocked state, the carriage 12b is automatically locked by initial operation.

(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 is guided by guide rollers 46z,
It is set so that it is stretched between 4 and d*.

Adapter locking means 6 is provided on the upper portions of both supports 4g and 4h.
is provided. The 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 hook 6a when the ribbon adapter A is loaded into the ribbon cassette B. Further, 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) This ribbon cassette B accommodates an ink ribbon 7 as shown in FIG. A supply core 8c and a take-up core 8d are rotatably accommodated 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 81 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 filter 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 can be attached to the tip of the arm portion of the ribbon cassette B. The protective cover 9 is formed with protrusions 9a that protrude from the inner surfaces of both sides, and when the cover 9 is attached to the tip of the arm, the protrusions 9a fit into and lock in the locking recesses 81 of the ribbon force set (B). has been done. 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 H3 can be loaded into a recording device C, which will be described later, and for this purpose, locking protrusions 8j, which serve as retention means, are protrudingly provided on both side surfaces of the cassette case 8.

(Recording Apparatus) Next, the configuration of a recording apparatus that loads the ribbon cassette B and performs recording will be described.

As shown in FIG. 11, this recording apparatus C uses a recording means 12 to record on the first recording sheet conveyed by a sheet conveying means 10, and the recording means 12 in this embodiment is of a daisy-wheel type. It is configured to record by rotating the elements.

Next, the control procedure for loading the ribbon adapter A into the ribbon force center B and loading this ribbon center B into the recording device C 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 shift motor 14g is driven by a certain amount to move the cassette table 14a downward, and in step S6, the ribbon motor 5f1 is rotated forward by a certain amount to wind up the ink ribbon 7 by a certain amount. Further, the process moves to steps 87 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 121. Then, the process proceeds to step SIO, where 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 erroneous printing correcting operation procedure will be explained with reference to the flowchart of FIG. 16 et al. 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 312 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 S12, 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, thereby shifting the ink ribbon 7 to a position facing the selected type.

Next, in step S15, the ribbon motor 5f is driven in normal rotation to wind up a predetermined amount of the ink ribbon 7, and in step S16, the hammer solenoid 12h is driven to hit the selected type with the hammer 12i. The ink from the ink ribbon 7 is transferred to the recording sheet 11 for printing. 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.

Furthermore, if a correction signal has been input in step 311, the process moves to step 320 and the wheel motor 12f
is driven so that the type to be corrected faces the hammer 121, and in step 321 the carriage motor 12e is driven so that the carriage 12b moves to the position of the corrected character. Then, in step 522S23, the soft motor 14-g is driven, and the cassette table 14a is moved so that the correction ribbon 1 faces the selected type (the position where ■ in FIG. 13(a) faces the hammer 12i). Shift up.

Next, step S24. Proceeding to S25, the ribbon motor 5L is reversely driven to project the correction cam 5e in the direction of arrow e, as shown in FIG. 3(b), and bring the cam surface 5e into contact with the lever part 5bz of the feed lever 5b , push up, and send out a fixed amount of correction ribbon l.

Next, proceeding to step 326, 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 portion with the correction ribbon l as described above, the shift motor 14g is driven forward and backward as shown in steps 327 to S32 to move the cassette 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 day 1 as described above, in step S33, the ribbon motor 5f is
I is rotated in the normal direction to return the correction cam 5e to the standby position, and in steps S34 to S36, the cassette table 14a is shifted down, and the carriage 12b is returned to the standby position where printing can be performed at the corrected character position.

Further, if a processing signal other than the above-described print signal or correction signal, such as a sheet conveyance signal, is input in step Sll, the process moves to step S37 and the processing corresponding to the processing signal is performed. It should be noted that the sheet conveyance procedure and the like are well known, so a description thereof will be omitted.

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, in FIG. 13 (out of the printing positions of ■ to ■ in BL, when the print positions are ■ and ■, the process jumps to step 35B, when the print positions are ■ and ■, the process jumps to step S52, and when the print positions are ■ and ■, the process goes to step S44). Transition.

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 345. 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 7-124 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 S48. S
49, the cassette table 14a is shifted by one character. As a result, the position where the hammer 12i faces in FIG. 13 (al) becomes the position marked ■ on the ink ribbon 7. Shift down by one character at 348 so that the ■ position faces the hammer 12+).

Then, in steps S50 to S53, the cow YARIDGE 12
b is moved to the next printing position, the desired type is made to face the hammer 12i, and the type is struck by the hammer 12i to print.

Next, in step 354, 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 355. 356, the carriage 12b is moved to the next printing position. And step S57
At this point, the ribbon motor 5fI is driven in normal rotation to wind up the ink ribbon 7 for one character. With this, Hammer 12i
The position of the ink ribbon 7 facing the ink ribbon 7 is the position (■) in FIG. 13 (■) (if the position printed in step S53 is the position (■) in FIG. 13(b)). 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 and cassette chiffle 1
Shift up 4a by one character. As a result, the position where the hammer 12i faces in FIG. 13(a) becomes the position ▪ of the ink ribbon 7 (the position printed in step S46 is 0 in FIG. 13)). In step 34B, shift down by one character so that the position of ■ faces the hammer 12i).

Next, in steps S63 and 64, the cow ridge 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 an unlocked state, it can be automatically locked by initial operation of the carriage 12b, and the ribbon mode P-5f for winding the ink ribbon 7 can be used to adjust the ribbon. It is possible to operate the correction cam 5e that sends out 1.

[Second example]

In the first embodiment described above, the ribbon adapter A is loaded into the ribbon cassette B, and this ribbon cassette B is inserted into the recording device C.
