Therefore, if the carriage is moved to the end of the movement range by the initial operation of the recording apparatus, the locking means will automatically lock prior to creating or correcting the recording operation.

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

[First embodiment]

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.

Fig. 1 is a perspective explanatory view of ribbon adapter A and ribbon cassette B, Fig. 2 (a) is an exploded explanatory view of the ribbon supply part of ribbon adapter A, and Fig. 2 (b) is a ribbon winding diagram of ribbon adapter A. FIG. 4 is an exploded explanatory view of the parts and the ribbon feeding mechanism.

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

(Overall Description) In this ribbon adapter A, as shown in FIGS. 1 and 2, a correction ribbon 1 is wound around a supply means 2 and a winding means 3, and both means 2 and 3 are rotatable around a support frame 4. is attached to. 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 2ag on one side of the flange portion 2a, and a spool locking portion 2as is formed protrudingly on the other side. A locking protrusion 2aa is protrudingly provided on the spool locking part 2as, and when the supply spool 2b is fitted into the spool locking part 2a's, 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 be engaged with the protrusion 2aa and rotate integrally.
A locking protrusion 2a5 is formed on az to prevent the fitted supply spool 2b from falling off from the spool locking portion 2az.

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 torsion coil 2d tightens the base 2az when the spool support member 2a rotates in the direction of arrow a of the barrel (the direction in which the supply spool 2b pays out the correction ribbon 1) in FIG.
It is wound so that the tightening is released when it is rotated in the opposite direction. 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 2a of the coil 2d comes into contact with the locking protrusion 4b, and the coil 2d comes into contact with the locking protrusion 4b.
The rotation of d 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 2d1 comes into contact with the regulating protrusion 4c protruding from the support frame 4, and the coil 2d is for regulating the rotation of the supply spool 2b.
The correction ribbon 1 wound around the base film forms an adhesive layer on a long base film, and this ribbon 1 is passed from the supply spool 2b to the support frame 4 shown in FIGS. It is guided from the flanged guide roller 4dl attached to the guide roller r: 14dz, and further from the guide roller 4d3 to the flanged guide roller 4d4 to the take-up spool 3 serving as the winding means.

(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. Furthermore, a sawtooth portion 3e is formed inside the collar portion 3b to engage with a sawtooth portion 5a1 formed on the side surface of the mold wheel 5a. This take-up spool 3 is rotatably attached to a spool shaft 4e projecting from the support frame 4 with the model wheel 5a and the feed lever 5b interposed therebetween.

The mold wheel 5a is also rotatably attached to the spool shaft 4e. A pawl portion 5a is formed on the circumference of the mold wheel 5a, and a feed pawl portion 5b+ of a feed lever 5b engages with this pawl portion 5ax, forming a so-called ratchet mechanism. In this ratent mechanism, when the feed lever 5b rotatably attached to the spool shaft 4e is rotated in the direction indicated by the arrow of
The mold wheel 5a is rotated 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. Then, the feed lever 5b is moved as shown in FIG.
As shown in a), when rotating in the direction of the arrow d, the feed claws 5h and 5b do not engage with the claws 5bz, and the mold wheel 5b is configured not to rotate.

A locking protrusion 5bs is provided on the feed lever 5b.
A tension spring 5c is attached between this protrusion 5b and a hook portion 5g+ of a long 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. There is.

Furthermore, as shown in FIGS. 3(a) and 3(b), a reversal prevention claw 5d is attached to the side surface of the support frame 4, and the reversal prevention claw 5d is engaged with the claw portion 5a2 of the mold wheel 5a. It is composed of 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, the correction cam 5e is slid in the direction of the arrow e as shown in FIG.
Alternatively, the flat part 5es is brought into contact with the lever part 5bz and pushed up, and in this state, the ribbon cartridge B loaded with the ribbon adapter A is shifted in the direction of the arrow f in FIG. The portion 5b2 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 FIGS. 3(a) and 3(b), a rack 5et is formed on the side surface of the correction cam 5e. The rank Set is shown in FIG. 4(a) to (
As shown in C), it meshes with a cam gear 5e4 that is rotatable around a shaft 5e+, and the correction cam 5e is configured to be slidable on the carriage by rotation of the cam gear 5e4.

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 driving means 5f, an idler gear 5f4 that rotates around a shaft 5f provided on the carriage meshes with a pinion gear 5h attached to the motor shaft of the ribbon motor 5f+. An arm 5f is attached to the shaft 5f3 and is rotatably supported around the shaft 5f. An idle gear 5f that rotates around a shaft 5fb is supported at the tip of this arm 5f5, and this idle gear 5r
, is meshed with the idler gear 5f. The idle gear 5rr is attached to the arm 5f by a wave washer that does not rotate so that some load is applied to the rotation.

Therefore, when the idler gear 5f4 rotates, the idle gear 5ft is configured to rotate around the idler gear 5fa as the arm 5f5 rotates while remaining in mesh with the idler gear 51a. The idle gear 5r is configured to mesh with the cam gear 5e when the arm 5f rotates in the direction of arrow g, as shown in FIG. 4(a).

Therefore, when the ribbon motor 5fI is driven in reverse (rotated in the direction of the arrow in FIG. 4(a)) with the idle gear 5ft meshing with the cam gear 5e4 as shown in FIG. As shown in FIG.
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 part 5es in contact with the lever part 5bz, the ribbon 1 is further modified.
is 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. In addition, when shifting the adapter A upward, the lever part 5bz is moved by a reversal prevention pawl 5d, etc., which will be described later.
Even if the correction ribbon 1 returns, the correction ribbon 1 will not go back.

Incidentally, as shown in FIGS. 4(a) to 4(C), a tension spring 5fe is attached to the correction cam 5e. Therefore,
As shown in FIG. 4(b), when the ribbon motor 5L is driven in normal rotation (rotated in the direction of arrow i in FIG. 4(b)), the arm 5fS rotates in the direction of arrow j, causing the idle gear 5r to rotate.

The meshing between the cam gear 5ea and the cam gear 5ea is examined, and the correction cam 5e slides in the direction of the arrow and retreats by the bias of the tension spring 5rs. 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 the arrow d, but the rotation of the mold wheel 5a is restricted by the anti-reverse claw 5d and does not rotate.Also, as mentioned above, when the arm 5r rotates in the direction of the arrow j, As shown in FIG. 4 fc), an idle gear 5f is configured to mesh with the ribbon gear 12. 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 long lever 5g is the take-up spool 3 attached to the spool shaft 4e.
The stop ring 5h is rotatably attached to a lever shaft 41 protruding from the side surface of the support frame 4 shown in FIG.
The shaft 41 is attached so that it does not fall off. This lock lever 5g has a first lock part 5gz and a second lock part 5gz, as shown in FIGS. 2 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 spool shaft 4e from falling off.

When attaching the take-up spool 3 to the spool shaft 4e,
As shown in FIG. 6, hold the lever part 5g and rotate it in the direction of arrow E to retract the locking parts 5gz, 5gs 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 engages with the locking recess 5b formed in the projection 5b of the feed lever 5b, as shown in FIGS.

Then, after attaching the take-up spool 3 to the spool shaft 4e, rotate it in the direction opposite to the arrow i 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 configured to automatically lock.

As shown in Fig. 7, the configuration for this purpose is as shown in Fig. 7, where a cut-out slope 5g is attached to the corner of the lever part 5gm of the locking member 5g.

In this state, when the locking protrusion 8j of the ribbon cassette B is pushed into the notch 14b by the hook 14d as shown in FIG. 14(b), the connecting portion 4f is pushed forward along the slope 15b, and the connecting portion 4r The front end is the stopper protrusion 15
It comes into contact with a. This positions the ribbon adapter A in the front-rear direction. At this time, the upper and lower surfaces of the connecting portion 4f are sandwiched between the lower surface of the ribbon cassette B and the upper surface of the cassette table 14a, and vertical positioning is also performed.

Therefore, since the ribbon adapter A is reliably positioned and fixed on the carriage 12b, when the correction cam 5e is driven, the cam 5e reliably operates the feed lever 5b of the ribbon adapter A. For this reason, both members 5b,
The positional relationship of 5e is not affected by the attachment and detachment of ribbon adapter A and ribbon cassette B.

(Control Means) Next, a control system for controlling the drive of each of the members will be described.

In FIG. 15, 16 is a control unit, and the MPU 16a

Next, the control procedure for loading the ribbon adapter A into the ribbon cassette B and loading this ribbon cassette 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 carry 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 is automatically made long 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 5f is rotated forward by a certain amount to wind up the ink ribbon 7 by a certain amount. Further, the process moves to steps S7 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 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 S12 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 and shift the ink ribbon 7 to a position facing the selected type.

Next, in step S15, the ribbon motor 5f1 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 hammer the selected type! By striking with 2+, the ink on the ink 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, proceeding to steps S22 and S23, the shift motor 14g 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 amp.

Next, step S24. Proceeding to S25, the ribbon motor 5f+ is reversely driven to project the correction cam 5e in the direction of arrow e as shown in FIG. 3(b), and the cam surface 5e+ contacts the lever part 5b of the feed lever 5b let it, push it up,
A fixed amount of correction ribbon 1 is sent out.

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 S27 to S32 to move the cassette table 1.
4a is moved up and down, the correction ribbon 1 is sent out by a certain amount, and the correction impact operation of driving the carriage motor 12e to slightly move the carriage 12b and hitting it with the hammer 12j 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
ft is rotated in the forward direction to return the correction cam 5e to the standby position, and in steps 334 to S36, the cassette table 14a is rotated.
At the same time, 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 343 which position on the ink ribbon 7 the printing position is. Then, in the case of ■ and ■ in the printing positions of ■ to ■ in Figure 13 (℃), step 3
The process jumps to step 58, and when the result is ■ or ■, the process jumps to step 352, and when the result is ■ or ■, the process moves to step S44.

For example, if the printing position is at the position (■) shown in FIG. do. As a result, the position where the hammer 124 faces in FIG.

Next, step S45. Proceeding to S46, the type wheel 12g is rotated so that the desired type faces the hammer 12i, and the type is struck with the hammer 121 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 34B, S
49, the cassette table 14a is shifted up by one character. As a result, the position where the hammer 12+ faces in FIG. 13(a) becomes the position of ■ on the ink ribbon 7 (if the position printed in step S46 is the position of ■ in FIG. 13, etc.), step 348 Shift down by one character and place ■ to face hammer 12i).

Then, in step 7, 550-S53, carriage 1
2b to the next printing position and place the desired type on the non-marker 12.
i and hit the printed characters with a hammer 12i to print.

Next, in step S54, it is determined whether or not there is next printing. If the recording is completed, 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 5f1 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 indicated by ■ in Fig. 13 Φ).
(The position printed in step S53 is the 13th
When it is in the position of ■ in figure (b), it is in the position of ■.) Then, the process moves to step 35B and S59, and 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. Shift down by one character at 548 so that the position of ■ faces the hammer 12i).

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 an unlocked state, it can be automatically locked by initial operation of the carriage 12b, and the ribbon motor 5f+ for winding up the ink ribbon 7 can automatically lock the ribbon cassette B. It is possible to operate the sending correction cam 5e.
