Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette printing ribbon arrangement of a printing device, of the type for printing onto a record carrier by means of a single printing redon.

BACKGROUND OF THE INVENTION Currently, for convenience of operation, printing materials are most often housed in cassettes. In that case, the print ribbon is typically placed in a "lying" position on a print cradle or print carriage. If the printing ribbon is wound on a reel, the axis of the reel is located vertically and the endless printing ribbon is placed in a so-called closed cassette (5topfkas).
sette), the printing ribbon itself is positioned vertically during its travel. For printing presses that are used many times, the use of a refill ink roller significantly improves the printing life compared to the capacity of the cassette.

Problems to be Solved by the Present Invention However, the so-called one-time printing presses, in short, carbon printing presses for one-time use, magnet case printing presses, and multicolor printing presses, are used only once. ), the cassette must be significantly larger to store sufficient print reparation. Therefore, with a "lying" cassette, the space for placing the printing device on the table or for keeping the printing device on hand is significantly larger.

Therefore, an object of the present invention is to store a sufficient amount of printing liquid and to save the labor of frequently replacing the printing liquid, thereby making it possible to improve printing apparatuses, especially those equipped with one-time printing IJ and d-ton. The purpose is to make it easier to operate. The premise behind this is that it is possible to install a relatively large printing resin roll, which would require a significant increase in space if the printing IJ and d-con cassettes were placed ``laying down'' on a public road. It is to do so.

Means of the Invention Solving the Problems The present invention solves the above problems by providing a cassette-type printing device for printing on a record carrier from a one-time printing resensor. can be inserted into the printing device in an "upright" state, the cassette can be locked in the upright position by a guide/locking member in its insertion position, and Via the freely guided printing ring, printing is carried out by the printing head from top to bottom in such a way that, depending on the size of its reel, the cassette projects slightly upwards from the printing device casing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As can be seen in FIG. 1, the entire printing device is housed in a housing 1, which surrounds the printing device on all sides. The casing 1 is provided at its front end with an opening 2 through which a guide table 3 passes through which is the reservoir of the record carrier 36 to be transported. A supply n4 is provided on the upper side of the casing 1, and a cassette 5 with a printing lithium 20 (FIG. 2) is placed in this supply port.
is inserted. The width a of the supply n4 is approximately twice the height and thickness h of the cassette 5. The cassette 5 is arranged "upright", so that the axes of its reels 77, 78 (see Figure 5) lie approximately horizontally (in contrast to the vertical axes of conventional cassettes). ).

As shown in FIG. 2, the guide table 3 has two lateral guide edges 6.7. The upper guide plate 8 is its front edge 9
The guide cylinder 10 is bent at the 78th position of the recording medium 36 to be printed. Pressing rollers 13, 14 are visible through the cutouts 11, 12 provided in the upper guide plate 8, and the pressing rollers 13, 14

The gear 19 drives a shaft 19' to which drive rollers 15 and 16 are fixed. The motor 17 can be driven in reverse, so that the record carrier 36 is moved in the retraction and ejection directions.

As can be seen in FIG. 2, the print +7 +% 20 comprises three ribbon bands 21, 22, 23.

The colors of +J Sen bands 21, 22, and 23 are yellow, magenta, and cyan, respectively. Print ribbon 20 is drawn from storage reel 77 by a drive acting on roller 79 and wound onto reel 78 . The middle ↑ is printing ribbon 2
0 passes through the printing area 2 located outside the cassette 5. This printing area 2 is located at the bottom in FIG. 1 when the cassette 5 is inserted. The printing spatula 124 has support parts 25 and 26.
and a thermo head 27 (FIGS. 3 and 4), and a 4-mo printing member is supported by this thermo spatula l'27. The support 25 of the printing spatula 24 is guided movably in the row direction on a shaft 28 and at the same time via a projection 29 along a stationary strip 30. As a result, the support part 25 is capable of translational movement but not pivotable.

In contrast, the support 26 is guided only on the shaft 28 and can be pivoted clockwise (as seen in FIG. 1) by means of springs 31 hooked on both sides, so that
The thermospatula 127 is mounted on the printing beam 32 as it moves from left to right in the printing direction.

Support part 25 of print head 24. ．． Between 26 and 26, a spring-elastic squib 33 is fixed, the multi-folded spring-elastic projection 34 of which rests with its front end 35 on the guide plate δ, which also in particular As can be seen, it rests between the printing ribbon 20 and the record carrier 36. This screen ξ33 is formed as a spring curved member, and the print head 24 is located at its printing position (Fig. 1).
It is arranged so that it always rests elastically on the upper paper guide, irrespective of whether it is in the raised position or in the raised position (FIG. 3). As is clear from a comparison between FIG. 3 and FIG. 3a, in the printing device (FIG. 3), the thermostylus R27 is pressed against the print resensor 20 and the record carrier 36, and the screener ξ is located right next to the thermohead. Printed at the rear IJ, d
The main body 20 and the record carrier 36 are separated.

In FIG. 3a, when the printing spatula 124 swivels backwards, it moves away from the printing IJ , , = 1720, so that the printing ribbon 20 in the cassette 5 can easily touch the printing spatula P24 in the printing area 2, and the elastic It is inserted between the printing beam 32 and the protrusion 34 and front end 35 of the scraper 833 mounted on the guide plate 8.

A swivel is provided on the back side of the support 25 so that the print head 24, in particular its support 26, and thus the thermospatula F'' 27 fixed thereto can swivel relative to the support 25 against the force of the spring 31. A lever 37 is mounted, which swivel 37 cooperates with a stop pin 38 in its right end position so that the swivel 37 pivots, so that the support 26 also pivots. It is pivoted relative to the support part 25, and thus the support part 26 and the thermospatula F'27 are also lifted.In its left end position, the pivot part 37 cooperates with a release claw (not shown). This release pawl causes the pivot 37 to pivot to its other end position, thereby bringing the print head into the printing position shown in FIGS. 1, 3 and 4.

A second motor 39 is used for driving the print head 24 in the row direction, for driving the print ribbon 20 and for moving the cassette 5.
is used, and the motor 39 has two gears 40
．． 41 drives the row 242, and the drive belt 43 is tensioned via the roller 42. The drive belt 43 is wound around a roller 44 on the other side. Both ends of the drive belt are elastically hooked onto the printing spatula 124. A detection plate 46 is connected to the motor shaft 45, and the position of the print head 2 is transmitted to the electronic control device by this detection plate. The detection plate 46 cooperates with a photoelectric device (not shown). The reciprocating movement of the printing spatula r24 is performed by a motor 39 consisting of a DC motor.

A drive member 48 is driven via a reduction transmission 47 that includes a freewheel. This driving member 48 is inserted into the recessed portion 75 of the roller 79 of the cassette 5 and drives the printing sensor 20 (FIG. 5). By means of a freewheel provided in the reduction gear 47, the print +J sensor is driven only during the return movement of the print head 24, when the support 26 and the thermospatial plate 27 are in the raised inactive position shown in FIG. 3a. Ru.

Then the cassette is inserted into the supply n4 of the casing 1,
The manner in which it is connected to the drive member 48 and engaged by the guide and locking member will now be described.

The cassette 5 is provided with a recess 49 (FIG. 5) on its right-hand edge, into which a guide strip 50 provided on a printing device stand 51 engages.

Furthermore, cutouts 76 are provided on both sides of the cassette, into which the projections 53 of the spring-elastic locks 52 engage. To simplify the drawing, the locking on the left side
Only 52 is shown in FIG.

A spring-elastic locking lever 5-52 is mounted on an axle 54 (FIG. 1). A tabbin 55 is installed on this locking rail 5-52.
is cooperating with the cam track 56. cam track 56
has three locking recesses 5 spaced apart by 120 degrees.
8 and a plate 57 with one cam groove 59. Board 5
7 is supported on a shaft 60. When the plate 57 is rotated by the shaft 60, the pin 55 moves within the cam groove 59,
The locking reno-52 is printed, +7 n's ridge band 21,
22. It is pivoted into three different positions corresponding to 23. In the position shown in FIG. 1, the projection 62 of the locking spring 61 engages in the locking recess 58 of the plate 57. In this position, the cassette 5 occupies the most retracted position downward.

When the plate 57 is rotated 120 degrees clockwise, the next locking recess 58 engages the protrusion 62 of the locking spring 61. At that time, the locking lever 52 pivots clockwise in FIG. 1 via the cam groove 59 and pin 55, thereby causing the printing ribbon 2
The next bond zone 22 is brought into active position.

When the plate 57 is further rotated by 120 degrees, the third locking recess 58 of the plate 57 cooperates with the protrusion 6'2 of the locking spring 61, and the locking rail 5-52 is further rotated clockwise to the right. The third IJ, d-band 23 of the printing IJ sensor 20 is brought into active position. A subsequent rotational movement of the plate 57 returns the locking Lennonie 52 via the cam groove 59 to the starting position.

The plate 57 is connected via a shaft 60 to a belt roller 63, via which a drive belt 64 is guided. This drive belt 64 is elastically fastened to a drive lever 65, which is pivotably supported by two bent ends 66 on a support pin 67. Drive rail: -65 is printing, spatula 1:'2
It is operated by a pin 68 fixed to the support part 26 of 4. The drive rails 65 have bent edges 6 for this purpose.
9, and by this edge 69, the drive levers 6
5 is supported by a pin 68. When the printing spatula r24 moves from right to left, the drive ray z-65 pivots and transmits its drive movement via the drive belt 64 to the belt roller 63 and thus to the plate 57. When the pin 68 passes the end 70 of the edge 69, the drive movement ends and therefore no more drive movement is transmitted. When the printing spatula r24 moves from left to right, since the printing spatula r24 is lowered during this movement,
-768 does not engage edge 69.

Operation of the present invention Next, the operation of the present device will be explained. First, the cassette 5 is inserted into the supply port Φ and held in contact with the front wall of the supply n4. When cassette 5 is attached to Kakka-8,
When it is pushed downwards, the recess 49 and the guide strip 50 cooperate, and the protrusion 53 of the locking lever 52 is pushed downwards into the recess 7.
6, and the reduction transmission 47 and the drive member 8 are engaged. At that time, the support 26 of the printing spatula 124 and the thermo-head 27 enter into the printing area Z between the wall of the cassette 5 and the printing ribbon 20, and the screen 34.35 enters between the printing ribbon 20 and the record carrier 36. (Fig. 3,
(See Figure 3a).

The record carrier, preferably made of ordinary paper, is placed on a guide table 3'' and pushed through a guide tube 10 and pressed against a pressure roller 13. ．． 14 and drive rollers 15, 16. These rollers are rotated so that the record carrier 36
The record carrier 36 passes between the printing blade +y 24 (see FIG. 3), which in this state is swiveled upwards, and the printing beam 32. The record carrier 36 then impinges on the paper guide plate 71, as can be seen in particular from FIG. In its neutral position, this paper guide plate occupies the position shown in broken lines in FIG. 4 by means of a weight 72, so that the record carrier is pushed into a guide channel 73 at the rear of the printing device. Paper guide board 7
2 is then pivoted by the record carrier into the position shown in solid lines. The role of this paper guide plate 71 is to allow the record carrier 36 to be easily pushed down during the printing process.

When the record carrier 36 reaches its first row position, the printing device is driven by the electronic control unit and the motor 39 is started to cause the printing spatula r24 to reciprocate. Printing spatula P24
During the left-to-right movement of the printing ribbon 20 , the ribbon band of the printing ribbon 20 is brought into contact with the record carrier 36 . When the print spatula r24 moves from right to left, the print head 24 rotates...-3
7 and the print head 38 so that the print head does not come into contact with the print ribbon and the record carrier.

During this movement, as already mentioned, the drive...65
The movement of the cam track 56 causes the print lean 20 to cooperate with another lean band of the next print run of the print head. When the print head prints the third print from left to right, one line is printed in color. The record carrier is advanced by one line via the motor 17 and the gear wheels 18, 19, and then a new line is printed by three new printing passes of the print head.

Advantages of the Invention According to the present invention, the cassette can protrude upwardly beyond the volume of the printing device by an arbitrary amount, the printing device can be loaded with a cassette of any size, and therefore the printing volume can be increased with respect to the printing ribbon. Advantageously, it is possible to choose between small cassettes with a small storage capacity and large cassettes with a large printing ribbon storage capacity.

The disadvantage of an upright cassette is that the impression is not visible at the time it occurs. However, considering that the high speed f of modern data printing devices makes it impossible to keep track of the data being printed and does not brake in a timely manner even when an undesirable r-time appears, the above-mentioned Another advantage of the invention is that the cassette can be easily inserted, without having to "thread" the print IJ H,'n into the printing device during insertion, or wrap it around the guide member. The reason is that there is no need to hang it at all. Moreover, there is no need to open the flap of the casing before inserting the print risen. This means not only ease of operation, but also simplicity of the casing construction, since no removable or pivotable flaps are required.
