Abstract

PURPOSE:To obtain a serial type printer capable of performing printing operation by a set of hammer and having a smaller thickness by a method in which the hammer can be driven only when types to be printed are present in the type wheel when the supporter leg of the type wheel reaches the projection of the hammer. CONSTITUTION:When a shaft 7 turns in the direction of arrow A, a type wheel 1 is turned in the arrow direction, and when desired types reach a set position, a clutch 34 is coupled and a hammer 30 is raised by a cam 33. Then, the supporter leg 4a of the type wheel 1 is struck by the projection 30a for printing. The cam 33 turns one round, the clutch 34 is disconnected, a clutch 27 is connected, a drum 26 is turned, and a carriage 13 is moved by half pitch of the comb teeth in the direction of arrow E by a wire 24. The supporter leg 4a of the type wheel 1 is faced a concaved part 30b, and the supporter leg 5a of the type wheel 2 is faced the projection 30a. When no desired types are present in the type wheel 2, printing operation is stopped, and only when the type wheel 1 reaches the digit, printing is made.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a/real type gamma 2' printer having a type wheel.

There is a real-type type printer in which a type wheel is supported on one private axis and the type wheel is sequentially pressed against paper while moving in the row direction (vrc) to print. By the way, there is a relationship between the size of the type wheel and the size of the type, and there is a limit to how small the type wheel can be made for the selected type.

Therefore, there is a restriction that II; I: cannot be expanded below the thickness that is determined by the type wheel. Therefore, the thickness of the printer can be made thinner by dividing the necessary 16 characters into two or more 2-piece wheels, rearranging them, and selecting a type foil for printing. .

SUMMARY OF THE INVENTION The present invention seeks to provide a printer with a plurality of type wheels having a simple construction.

The printer according to the present invention includes a plurality of two wheels in which the parts necessary for printing are arranged in a distributed manner, a support that rotatably supports each of the parts, and a printing wheel that connects the part of the valley support to the printing ring. means for supporting the carriage so that it can be moved in the straight direction; a gear ridge A' that is secured to the support and moves the carriage in the straight direction; and a device for transporting the carriage; At one end of the tube support there is a gear mechanism that rotates each type wheel.
・It consists of a hammer unit and a device that drives the hammer unit, and the projection engages with the support body by the operation of the hammer unit, and the support body and type wheel are separated. q-+ hy to drive and print.
That is.

To explain with reference to the figure below, in the illustrated example, the typefaces that must be printed consist of only numbers, the numbers from 0 to 9 are divided into two, and the typefaces in the minority area are divided into two. In the Chinese translation 1,
The remaining printed words are included in the second printed ring. 1111 type wheel 1. A gear 6 (not shown in the figure) is fixed to the 1111IiTl], and a gear 6 (not shown in the figure) is fixed to the support 4 having a 1dV shape in the 11th divination wheel. 11'' 116V Rotation ``T'' The second rod ring is rotated from the qlllll 6)l VC which is solidly attached to the support body 4 and the concave shaped support body. It is placed in the wide-mouthed f-mouth, and the graphic character wheels are arranged in a nu+j4#l\-like manner.

On the other hand, the carriage 16 slides astride the shaft 12 provided parallel to the drive shaft I7 and the shaft.
The leg 1 of the support body 4.b is

The carriage and the I-shape (1δ1, 2 and Tagawa d) are moved as one body to the shafts 7 and 12. On the sides of the supports 4 and 5, Bin 16・1/
One end of the springs 21 and 22 wound around the bottles 18 and 19 of the carriage is hung on this.
The bottles 16 and 17 of the supports 4 and 5 are brought into contact with the spears 2 to soak the supports, that is, the type wheels 1 and 2.

A wire 24 is connected to one end of the gear ridge 16, and the wire is wound around a drum 26P. The drum is connected to a pulse motor (not shown) via an electromagnetic clutch 27 and an O-nanton 28.

On the other hand, at the lower ends of the legs 4a-ba of the support beams 4 and 5, an integral piece 60 is swingably supported by a lilil 61. The cam 66 is in contact with the cam follower 62, and the cam 66 is connected to a pulse motor (not shown) via an electromagnetic clutch 64 and a southeast 65. C and C are designed to swing downward in the same manner. 1 hammer 60r presses the tooth-shaped protrusion 60a and the recess 3[Jb], and when the force leg 4a is facing the protrusion 6[1a], the other The leg of the sled is opposed to the fourth part 30b which is shifted by one and a half pitches from the soil sled. That is, the leg portions 4a and 4b are in relative positions shifted by a half-pinch of a pitch of 1 quadrangle. Add 1 to the divination wheels 1 and 2. (They are arranged at intervals of half a pinch of heating. The intervals between the legs i'11i may be one and a half pitches or more apart.

A perforated disk 67 for conveniently placing the type in one position is fixed to the drive 07, and a nine-ton device 66 is provided opposite to this. Further, on the shaft 6B of the drum 26, a disc 40 with a hole for transporting the sheath and a photoelectric device 41 are provided. In addition, the same Atu 46 is interposed between the type wheel and the platen 4.
2 is provided.

Next, we will read about the effect. Before printing,
The electromagnetic clutches 27 and 64 are disengaged, and the electromagnetic clutch 10 is engaged. In the illustrated state, the printing power button 1 by the first character wheel 1 is at its lowest level. As the shaft 7 rotates in the direction of arrow A, the type wheel 1 rotates in the direction of arrow B via gear δ・6, and 19T
When the main character reaches the set position, the clutch 64 is engaged, and the cam 66 causes the numeral unit 60 to move in two rows against the spring 45, and the projection 6t]u or the 11th divination wheel 1 The support legs 4 are swung around the shaft. At this point, the letters 7b and 1 are exposed in the direction of arrow C, and the letters 19 and 19 press the claw 46 against the platen 42, and the letters are printed. Germany!~Also, I'm supplying 1 Inkke.When printing, even 1"s inserted by Kufunochi 1U has no problem in printing.

When the printing is completed 17, the hammer unit 60 is tilted by the force 1.66, and the support body 4, that is, the active ring 1 is tilted backwards by the force of the spring 21. When the cam 66 rotates once, the clutch 64 is disengaged. The 11 clutches 27, which were replaced by the clutches 64, are engaged to make the tram 26 turn once.
The wire 24 allows the carriage 16 to be moved half a pitch in the direction of the arrow (4)E.
