[0002]

2. Description of the Related Art Generally, in a recorder, various recording data such as various measurement data and accompanying data are recorded on a recording medium such as a belt-like recording paper called a chart. In this type of recorder, the above-mentioned band-shaped recording paper is stored in an unused portion and a recorded portion separately in respective storage portions at the lower portion of the instrument main body, and provided in the middle of paper feeding between these storage portions. The data recording on the recording paper is performed by allowing the ink ribbon and the wire hammer that strikes the ink ribbon toward the outer peripheral portion of the platen roller to face the abutted portion as recording means. There is known a configuration in which printing is performed as a dot recording.

In the recorder described above, the storage sections for the recording paper are arranged side by side below the main body of the instrument, and the recording paper is made to travel while being attached to a platen roller disposed above the instrument. In addition, an ink ribbon cassette is arranged on the upper end side of the platen roller, and stored in this cassette.
In general, a wire hammer is arranged so that the running portion of the stored ink ribbon is exposed and the ink ribbon can be hit from the back side.

FIG. 4 shows a schematic configuration of a portion near a printing mechanism on the recording paper 1 in such a conventional recorder.
Here, reference numeral 2 in the figure denotes a platen roller to which the recording paper 1 which is fed from an unused recording paper storage unit arranged below to a used recording paper storage unit (both not shown) is attached. This is an ink ribbon cassette that is disposed with the running portion of the ink ribbon 4 provided on the rotation end side facing the upper end side of the platen roller 2.

[0005] Reference numeral 5 denotes the ink ribbon cassette 3 .
A wire hammer that is arranged facing the back side of the ink ribbon 4 in the ink ribbon traveling section provided on the rotating end side (lower end side) and is operated to strike the outer periphery of the platen roller 2. The ink on the ribbon 4 is printed on recording paper. In the drawing, reference numeral 6 denotes a carriage for holding the wire hammer 5 and moving it in the width direction of the recording paper 1 to perform dot recording at a predetermined location. Reference numeral 7 denotes an armature for causing the wire hammer 5 to perform a dot driving operation in a vertical direction. is there.

In the drawing, reference numeral 8 denotes a shaft supporting portion for rotatably supporting the ink ribbon cassette 3. When the ink ribbon 4 is of a multicolor type, its position relative to the wire hammer 5 is displaced. It is also used to rotate to the retracted position when checking the printing state on the recording paper 1 on the platen roller 2. Further, reference numeral 9 in the figure denotes a display for displaying various information, which is arranged at the upper end of the front part of the instrument main body in the recorder.

In the recorder having such a configuration, the wire hammer 5 is opposed to the recording paper 1 at a predetermined position by the carriage 6 at the printing position at the upper end of the platen roller 2, and the shaft support 8 is provided on the upper end side of the instrument body. Support
The ink ribbon cassette 3 is rotated was in this Inkuribo
Increment provided on the rotation end side (lower end side) of the cassette 3
Ink printing is performed by causing the ink ribbon 4 in the bon travel portion to face between the wire hammer 5 and the recording paper 1 attached to the platen roller 2 and causing the wire hammer 5 to perform a spotting operation .

[0008]

In the conventional structure as described above , the ink ribbon cassette 3 is rotatably supported between the side plates of the instrument main body so as to face the printing position on the upper end of the platen roller 2. Since it is necessary to provide a platen roller 2 and a recording paper storage unit (not shown) below the platen roller 2 below, the shaft support portion 8 of the ink ribbon cassette 3 is arranged as shown in FIG. The upper end of the instrument body where it is installed
It was common to provide them in parts .

However, in such a configuration, the radius of rotation from the shaft support portion 8 of the ink ribbon cassette 3 to the running portion of the ink ribbon 4 facing the outer peripheral portion of the platen roller 2 cannot be made large. There was a problem. That is, in the recorder described above,
As the ink ribbon 4, a multicolor type in which a plurality of color bands are arranged in the width direction thereof is generally used. In particular, the minimum width of each color band in such a multicolor ink ribbon 4 is 2 mm. For example, in the case of the ink ribbon 4 of six colors, the ribbon width is 12 mm. In the multicolor ink ribbon 4 having such a wide ribbon width, the rotation angle of the ink ribbon cassette 3 at the time of performing color switching becomes considerably large in inverse proportion to the rotation radius a.

Therefore, in order to switch the color of the multicolor ink ribbon 4, the ink ribbon cassette 3 having a small turning radius a as shown in FIG.
When turned, the relative angle is large,
The cassette 3 swings greatly from the state shown by the broken line in the drawing, whereby the ink ribbon 4 on the side of the cassette 3 changes from a state perpendicular to the direction of the hitting operation of the wire hammer 5 to an inclined state. Since the wire hammer 5 hits the ink ribbon 4 inclined as described above, it is inevitable that the ink ribbon 4 is damaged.

Similarly, the running portion of the ink ribbon 4 on the rotating end side of the ink ribbon cassette 3 and
The required gap between the platen rollers 2 to which the recording paper 1 is engaged also increases as the turning radius a of the ink ribbon cassette 3 decreases . This corresponds to the lower end of the ink ribbon cassette 3 indicated by a two-dot chain line in FIG.
It can be easily understood from the fact that a position shift as shown by x in the figure occurs due to the rotation locus at the moving end) .

On the other hand, the gap of the wire hammer 5 with respect to the outer peripheral portion of the platen roller 2 cannot be made so large from the viewpoint of printing characteristics.
The printing position is set to the upper end side of the platen roller 2, and the platen roller 2, the wire hammer 5, and the ink ribbon 4 are arranged so that the relative positions thereof are substantially vertical. However, even with such a configuration, the rotation angle of the cassette 3 is large depending on the size of the turning radius a of the cassette 3 from the shaft support portion 8 and the ribbon width of the multicolor ink ribbon 4,
Due to this , the rotation locus of the ink ribbon
The required gap becomes large, and the printing characteristics cannot be maintained properly. further,
If the rotation angle of the cassette 3 is large as described above, it is necessary to secure a space for disposing the cassette 3, and there is a problem that the entire instrument is enlarged.

Further , in such a conventional structure, in response to the desire to see the state immediately after printing at the printing location on the recording paper 1 on the platen roller 2 described above, for example, Japanese Utility Model Publication No. 4-16909, As shown in Japanese Utility Model Publication No. 4-16910 and the like, the ink ribbon cassette 3 is
As shown by a solid line in FIG. 4, there is known a structure in which the printing position is further retracted to the back side than the above-described color switching operation so that the printing location can be confirmed from the outside.

However, in the conventional recorder described above,
Swing the crib cassette above the platen roller 2
It is necessary to secure the required turning radius when supporting
Requires space in the height direction of the instrument body,
There was a problem that the size of the main body was increased in the height direction.
Further, in the above-described conventional recorder, the above-described ink ribbon
Ink ribbon running
Move the line section and the platen roller 2 close to each other and
It is difficult to narrow down to the minimum. In particular, the conventional
In the recorder, the ink ribbon running part is close to the platen roller 2.
If the ink ribbon cassette is
When replacing the ribbon or when the recording paper 1 on the platen roller 2
Large swing operation to check the printing status
When the side edge of the ink ribbon 4 is
There was a problem that it was damaged by contact with the surface.

Further , in the recorder, as shown by the imaginary line in FIG. 4, various information is displayed on the recorder near the upper end of the platen roller 2 and in front of the ink ribbon cassette 4. A display 9 and a front door (not shown) are provided. As shown by a solid line in FIG.
In reality, the print position P at the upper end cannot be viewed obliquely from above, so that it is necessary to take some countermeasure against such a point.

In particular, on the outer peripheral surface of the platen roller 2 as described above, the printing position that is most visible when viewed from the front side of the instrument main body is more than the upper end position P of the platen roller 2 in FIG.
The position Q is closer to the front and is inclined to the middle left side by an angle θ. Therefore, the wire hammer 5 is disposed at an angle θ,
If the printing is performed from that position, the state immediately after printing is easy to see. Note that this angle θ is 15 to 20
It is sufficient if it is ゜ or more.

However, in order to achieve such a configuration, the cassette 3 having the ink ribbon 4 as well as the wire hammer 5 is required.
It is necessary to change the arrangement position and the rotational operation range of the printer. However, as described above, in the recorder, the display 9 and the like are present on the front side, and it is difficult to secure the arrangement space for the ink ribbon cassette 3. However, this is a practical problem, and such a point must be considered.

The present invention has been made in view of such circumstances, and when performing multi-color dot recording on recording paper using recording means comprising a multi-color ink ribbon and a wire hammer for striking the ribbon, a platen is used. B.
Downsizing of the ribbon ribbon cassette in the height direction
In addition, it is possible to prevent the problem of damage to the ink ribbon, which has been a problem in the past, to make it easier to check the printing position from the outside, etc., and to reduce the size of the entire recorder without changing the number of recording colors. The purpose is to obtain a recorder that can be planned.

As shown in FIG. 2, the portion of the ink ribbon 40 extending between the projecting portions 43 and 44 of the cassette 41 (ink ribbon running portion) corresponds to the recording paper on the platen roller 30. Ink printing is performed on recording paper by facing between the wire hammer 20 and the wire hammer 20 being hit at a predetermined position. The structure of each part constituting the recorder 10 described above is conventionally well-known, and a detailed description thereof will be omitted.

According to the present invention , in the recorder 10 configured as described above, as shown in FIGS.
The ink ribbon cassette 41 that movably accommodates the ink ribbon 40 in a stretched state is attached to and detached from the rotating end portion 50a with the stretched portion positioned between the wire hammer 20 and the recording paper on the platen roller 30.

Further, in the above-described configuration, the multicolor ink ribbon 4 that is rotated relative to the wire hammer 20 is used.
The rotation radius c from the shaft support 51 to the portion (ink ribbon running portion) facing the platen roller 30 in the ink ribbon cassette 41 having 0 is determined by using the shaft support 51 on the front end side of the instrument body in the instrument body chassis. Plate
And the rotation angle of the multicolor ink ribbon 40 when the cassette 41 is rotated for color switching is reduced, and the distance between the wire hammer 20 and the platen roller 30 is reduced. Can be maintained in a minimum necessary amount, so that the ink ribbon 4 can be moved with respect to the hitting operation direction of the wire hammer 20 as in the prior art.
Since the ink ribbons 40 are opposed to each other in the oblique posture, the ink ribbon 40 may be damaged, or the gap may be increased to deteriorate the printing characteristics. And in such a configuration,
Since the rotation angle of the cassette 41 can be reduced as compared with the conventional case, the space for disposing the cassette 41 may be small, and the entire instrument can be downsized.

Further, the printing position on the outer periphery of the platen roller 30 may be shifted from the upper end to a portion near the front end of the roller 30, or the gap between the wire hammer 20 and the platen roller 30 may be small. Due to the small size, the printing can be performed relatively easily, thereby making it easy to see the printing position, and the state immediately after printing can be easily and reliably checked. This is because the ink ribbon cassette 41 is moved from the pivot end portion 50 of the cassette holder 50 away from the shaft support 51.
a, the color of the multi-color ink ribbon 40 can be switched even if the rotation angle is small, and the gap between the wire hammer 20 and the ink ribbon traveling portion and the platen roller 30 can be reduced, so that the ink ribbon 40 can be easily changed. Understood
You. Further, if the printing position is shifted toward the front end of the roller 30 as described above, the entire recorder 10 can be reduced in size. This is easily understood because the rotation angle of the ink ribbon cassette 41 is small and the inclination angle of the cassette 41 may be small, so that the arrangement space is reduced.
Is done.

Here, in order to adopt such a configuration and exert its effects, the carriage 21 for holding the wire hammer 20 should be disposed so as to be inclined obliquely forward as is apparent from FIG. . In particular, with this configuration, the rotational operation angle of the ink ribbon cassette 41 becomes small, and the platen roller 30, the wire hammer 20, and the ink
The gap between the wire hammer 20 and the ribbon running portion can be reduced to a disadvantage which is disadvantageous by disposing the wire hammer 20 at the forward inclined position.
It is possible to change the print position from 0 to a position that is easy to see on the platen roller 30. However, the present invention is not limited to such a structure. Needless to say, even when the printing position by the wire hammer 20 exists on the upper end side of the platen roller 30, the required operation and effect can be obtained.

The present invention is not limited to the structure of the embodiment described above, and it is easily understood that various modifications and changes can be made to the shape and structure of each part constituting the recorder .
For example, in the recorder 10 in the above-described embodiment, in the ink ribbon cassette 41 held by the cassette holder 50, the ink ribbon 40 is provided at the guide rollers 43a, The cassette 41 is provided with the guide rollers 43a, 44a inclined with respect to both the running surface inside the projections 43, 44 and the external running surface between the projections 43, 44. The outer running surface of the ink ribbon 40 is inclined with respect to the surface of the case.

This makes it possible to further shift the printing position on the outer peripheral portion of the platen roller 30 from the upper end to a portion closer to the front end of the roller 30, making it easier to see the printing position and to improve the state immediately after printing. Can be easily and reliably confirmed, and the size of the entire recorder 10 can be reduced as described above.

Also, according to the present invention, the ink ribbon 40
As an example, a multicolor type is described, and the operation and effect in the case of using the multicolor type are described.However, the present invention is not limited to this. There are advantages such as keeping it properly . In particular, such an advantage is significant in that it is not necessary to increase the size of the entire instrument main body when retracting the cassette in order to confirm the printing position.

[0042]
