Next, each operation in the embodiment configured as described above will be described.

In the printing operation, the motor 4 is driven in the state shown in FIG. 1B, and the type wheel 2 rotates accordingly, so that the predetermined type 3 is opposed to the predetermined position of the recording sheet 29. When the type 3 reaches a predetermined position, the rotation of the type wheel 2 is stopped, that is, the driving of the motor 4 is stopped. Then, the solenoid 10 is energized so that the shaft 11 of the solenoid 10 moves in the direction of the arrow 82 of FIG. 1b, and the hammer is centered on the shaft 9 via the hammer lever 8. Rotate in the direction of the arrow 4 in FIG. 1B, and hit the collector ribbon 31 several times with the hammer 7, for example, while rotating the recording paper 29, as shown in FIG. 6A. It is also possible to keep the platen 1, i.e., the recording sheet 29 stationary, and move the carriage ribbon 31 by the hammer 7, for example, several times while the carriage is moved slightly along the platen 1. It may be done.

7A, B, C, and D are explanatory views illustrating the process of factor correction in the factor correction operation described above. In these drawings, reference numeral 85 denotes an ink for forming a print on the recording sheet 29.

In the printing correction operation, before correction, as shown in FIG. 7A, the corrector ribbon 31 is kept separated from the recording paper 29. As shown in FIG. As a result of the rotation of the hammer 7, the corrector ribbon 31 is pressed against the recording paper 29 as shown in FIG. 7B. Then, as shown in FIG. 7C, the ink 85 that forms the print on the recording paper 29 in accordance with the retreat of the hammer 7 hits the type 3 of the type wheel 2 by the hammer 7. The typeface 3 is pressed onto the recording paper 29 wound around the ink ribbon 30 on the platen 1. Then, a desirable factor is formed on the recording paper 29.

In the printing correction operation, in the state shown in FIG. 1B as described above, the motor 4 is driven, whereby the type wheel 2 rotates, so that the character character 25 causes the recording paper 29 to be prescribed. It is controlled so as to oppose the printing modification position of the corrector, so that the corrector drive 25 is driven, i.e., the driving stop of the cutter 4 is performed. Subsequently, the solenoid 10 is energized, whereby the shaft 11 of the solenoid 10 moves in the direction of the arrow 82 in FIG. 1b, and the hammer 7 moves the shaft 9 through the hammer lever 8. The center rotates in the direction of the arrow 83 in FIG. 1B, and as shown in FIG. 6B, the hammer 7 presses the collector ribbon 31 against the collector characters 25 of the type wheel 2.

In this case, for example, the carriage is held by the hammer 7 while the carriage is held still and the platen 1 is micro-rotated as shown by the arrow 84 in FIG. 6B, that is, the recording paper 29 is moved. For example, the selector ribbon 31 may be struck several times, and the hammer 7 may be moved while keeping the platen 1, that is, the recording paper 29 stationary, and moving the carriage slightly along the platen 1. For example, the corrector ribbon 31 may be hit several times.

7A, B, C, and D are explanatory diagrams illustrating the factor correction process in the above-described factor correction operation. In these drawings, reference numeral 85 denotes an ink for forming a print on the recording sheet 29.

In the printing correction operation, before correction, as shown in FIG. 7A, the corrector ribbon 31 is kept separated from the recording paper 29. As shown in FIG. As a result of the rotation of the hammer 7, the corrector ribbon 31 is pressed against the recording paper 29 as shown in FIG. 7q. As the hammer 7 retreats, as shown in FIG. 7C, ink 85 forming a print on the recording paper 29 is attached to the collector ribbon 31, and the print on the recording paper 29 is removed. In addition, the ink adhering to the collector ribbon 31 is absorbed and dispersed in the collector ribbon 31 with time as shown in FIG. 7D. Therefore, printing correction was performed in the same location of the said corrector ribbon 31 in this corrector ribbon 31, for example. Even if it is, it is possible to modify several times.

Thus, as shown in FIG. 2A during the rotation of the hammer 7 in the printing operation and the printing operation, the curved portions 18 and 19 are provided in the standing portion 20 of the hammer lever 8. The curved portions 18, 19 are in contact with the flat end face 15, 16 of the shaft 11 of the solenoid 10 and the two clinical portions of the hammer lever 8 The narrow sections 14 of the shaft 11 of the solenoid 10 are sandwiched by the 20 and 21 so that the curved portion is moved in accordance with the movement of the shaft 11 of the solenoid 10. No vibration occurs between (18), (19) and end face 15, (16), and lower vibration between granular portion 20, 21 and narrow neck portion 14 is achieved. It does not occur, and the hammer lever 8, that is, the hammer 7, can be rotated smoothly.

Further, at the time of rotation of the hammer 7 in the printing operation and the printing operation, the recessed part 24 having the inclined surface 23 is formed on the front surface of the head of the hammer 7 as shown in FIG. 2B. On the other hand, a projection 27 having an inclined surface that can be engaged with the recessed portion 24 as shown in FIG. 3A on the back of the typeface 3 of the type wheel 2 and the back of the collector character 25. Since the type 28 is formed, each of the typeface 3 and the projecting portions 27 and 28 of the corrector character 25 when the typeface 3 and the corrector character 25 are hit by the hammer 7 is a hammer. The position can be set smoothly at a position suitable for the position in (7).

In addition, the drive means shown in FIG. 5 performs the operation | movement shown in FIGS. 8A-F according to rotation of the hammer 7. As shown in FIG.

FIG. 8A is a plan view showing the standby state of the typeface 3 before it is hit by the hammer 7, for example, FIG. 8B is a side cross-sectional view corresponding to FIG. 8A, and FIG. 8C is the typeface 3 by the hammer 7. 8d is a side cross-sectional view corresponding to FIG. 8c, FIG. 8e is a plan view showing a state when the hammer 7 returns to the standby state, and FIG. 8f is a view in FIG. 8e. Corresponding side cross section.

When the hammer 7 is in the standby state, that is, the state shown in FIG. 1B, the end portion 81 of the lever 75 is rotated by the force of the coil bar 80 as shown in FIGS. 8A and 8B. The leg portion 77 of the lever 75 is engaged with the shaft 11 of the solenoid 10 by engaging with the cut-out portion 86 of the cam 72. Therefore, in this state, even if the gear portion 74a of the DC motor 74 is to be rotated in the direction of the arrow 87 in FIG. 8A, the cut portion 86 of the cam 72 remains at the end portion of the lever 75. 81, the rotation is restricted in the direction of the arrow 88 of the cam 72, and the cam 72, i.e., the rotor 70, is locked in a non-rotational state.

When the type 3 is hit by the hammer 7, that is, at the time of rotation of the hammer 7, the shaft 11 of the solenoid 10 moves in the direction of the arrow 87a. The lever 75 moves in the direction of the arrow 88a in response to the force of the spring 80, and the lever 75 rotates in the direction of the arrow 72 in response to the force of the spring 81; Engagement of the end portion 81 of the lever 75 with the runaway portion 86 of the cam 72 is released. As a result, the lock of the cam 72, that is, the rotor 70, is released, and the gear portion 73 of the rotor 70 is rotated in the direction of the arrow 87 of the gear portion 74a of the DC motor 74. Rotates in the direction of the arrow 88, and the cam 72 and the gear portion 71 rotate in the direction of the arrow 88 integrally. Further, the gear portion 67 of the manual feed gear 61 moves in the direction of the arrow 89 of FIG. 8C, that is, the arrow of FIG. 5 in accordance with the rotation of the arrow 88 in the gear portion 71 of the rotating body 70. The ink ribbon 30 can be moved by rotating in the (90) direction as described later.

When the hammer 7 finishes hitting the typeface 3, and the hammer 7 returns to the standby state shown in Fig. 1b, the shaft 11 of the solenoid 10 as shown in 8e, f is shown. The lever 75 is rotated in the direction of the arrow 92 by the force of the coil spring 80, and the portion 86 of the cam 72 is moved to the end of the lever 75 by moving in the direction of the arrow 91. The rotating body 70 including the cam 72, that is, the gear portions 71 and 73, rotates in the direction of the arrow 87 of the gear portion 74a of the DC motor 74 until it engages with 81. In accordance with this, the direction of the arrow 88 is rotated, the manual transfer gear 61 is rotated in the direction of the arrow 89, and the ink ribbon 30 is moved.

In addition, when the escaped portion 86 of the cam 72 is engaged with the end portion 81 of the lever 75, the cam 72, i.e., the rotor 70, becomes locked as shown in FIG. 8A. .

Then, the cam 72, that is, the rotor 70, rotates 60 degrees, for example, during one reciprocating movement of the shaft 11 of the solenoid 10, that is, one hitting operation of the hammer 7. As described later, the ink ribbon 30 moves only a distance corresponding to one letter type through the ink ribbon transfer protrusion 59.

As described above, when the manual feed gear 61 rotates in the direction of the arrow 90 of FIG. 5, that is, the arrow 93 of FIG. 4B, in accordance with the rotation of the rotating body 70, that is, the gear portion 71, the manual feed is rotated. The rubber roller 60 and the ink ribbon conveyance projection 59 shown in FIG. 4 rotate in the direction of the arrow 93 in FIG. 4B integrally with the gear 61. As shown in FIG.

Then, the spool in which the protrusion 62 of the ink ribbon transfer protrusion 59 is biased by the coil spring 50 at the time of rotation of the ink ribbon transfer protrusion 59 in the direction of the arrow 3 in FIG. The ink ribbon 30 is rolled up to the side of the ink ribbon 30 wound on the 33) side, and is rotated in the direction of the arrow 94 in FIG. 4B of the portion of the ink ribbon 30 wound on the spool 33 side. Moves in the direction of the arrow 34 and is wound on the spool 33. In addition, the pivot 45 shown in FIGS. 4A and 4B is resistant to the force of the coil spring 50 in accordance with an increase in the amount of the ink ribbon 30 wound on the spool 33 in the direction of the arrow 95 in FIG. 4B. Is rotated.

In addition, as the rubber roller 60 rotates in the direction of the arrow 93 in FIG. 4B, the collector ribbon 31 moves in the direction of the arrow 34 in FIG. 4B. That is, the movement of the ink ribbon 30 and the movement of the corrector ribbon 31 are performed in synchronization. In addition, the ink ribbon 30 and the corrector ribbon 31 are guided along the tip portions 37 and 38 of the cassette lower lid 36 during the above-described movement.

In addition, by manually rotating the above-described manual transfer gear 61, for example, with the cassette containing the ink ribbon 30 mounted on the carriage, the looseness of the ink ribbon 30 can be easily eliminated. have.

In one embodiment configured in this way, as shown in FIG. 1B, the size of the height of the printer main body can be suppressed by arranging the type wheel 2 inclined with respect to the horizontal plane.
