[Prior Art] In a conventional recorder, a guide groove is provided in the depth direction of a main body in which a chart mount is housed, and rails are provided on both sides of the chart mount, and the rails of the chart mount are guided by the guide grooves. The chart frame is housed within the main body.

[Problems to be solved by the invention] There is a slight amount of play between the chart pedestal and the storage unit, which are pulled out and stored in such a storage unit, so that the sliding operation can be easily performed. clearance is required. However, this gap causes the chart mount to wobble in the vertical and horizontal directions, making it impossible to accurately set the distance between the recording device's dot tip and the recording paper fed to the chart mount, resulting in a stable recording condition. The problem is that it doesn't.

Furthermore, since the guide groove provided in the main body is formed longitudinally, there is a problem in that it is not easy to accurately provide the entire guide groove in the depth direction of the recorder.

This idea was made in view of the above circumstances, and it is possible to process a support member that replaces the rail by positioning it accurately on the main body without using the conventional rail. It is an object of the present invention to provide a recorder in which the chart mount can be stored in the main body with high precision, and the chart can be positioned optimally with respect to the recording device.

[Means for Solving the Problems] In order to achieve this invention, the recorder according to the present invention is provided with a recording device for recording input values at the top of the recorder body, and a recorder that can be freely drawn out and stored at the bottom of the recording device. The recorder is equipped with a chart mount, which has a plurality of cylindrical positioning tools positioned from the recording device installed in the depth direction on the recorder body, and the chart mount has a depth A guide groove is formed in the direction, and the guide groove is slidably held by a positioning tool, and the recording paper and the dot of the recording device can be positioned when the recorder main body is stored in the chart mount. .

[Function] According to the recorder described above, since the main body is provided with a positioning tool and the chart mount is provided with a groove, this cylindrical positioning tool can accurately position the chart mount. The recording state can be stabilized.

Furthermore, when the positioning tool is provided on the main body, processing is easy and costs can be reduced.

[Example] Hereinafter, an example of the recorder according to this invention will be described with reference to the drawings.

As shown in the perspective view of FIG. 1, the recorder 1 is provided with a display panel 2 at the upper part of the front surface, and a guide shaft 3 and a sliding shaft 4 are arranged at the back of the display panel 2 according to input signals. A recording device 5 is provided that can be moved and operated along the extending direction. This recording device 5 is composed of a print head 6 and an ink ribbon 7, and a plurality of dots 8 for recording protrude from the lower surface of the print head 6. Further, a chart pedestal 10 serving as a feeding device for the recording paper 9 is provided at a lower portion of the recording device 5 . Further, side plates 12a and 12b are erected from a main body frame 11 serving as a chassis to constitute a main body 13. The above-mentioned chart frame 1 is placed in the storage section 13a surrounded by these three members.
0 is installed so that it can be taken in and out. Note that the main body 13 can be moved in and out of the housing 14.

On the other hand, the recording device 5 is operated to move in the lateral direction according to an input signal value by a mechanism section (not shown).

Here, to explain the chart mount 10, a platen 1 that feeds out the recording paper 9 and runs it.
5, a gantry main body 16 integrally formed to rotatably support the platen 15, a storage section 17 in which the recording paper 9 is stored, and a gantry main body 16 extending from both lower end surfaces of the gantry main body 16 in the direction of the main body 13. It is roughly constituted by guide grooves 18, 18 on the left and right sides of the shape.

The guide groove 18 is provided with a step 18a in which the bottom surface of the guide groove 18 is formed one step higher at the frontmost part, and a side wall surface inside the guide groove 18 is provided slightly behind the step 18a and toward the rear of the groove 18. Deep grooves 18b and 18c are provided which are further recessed inward.

A chart drive unit (not shown) is housed in the gantry main body 16, and the chart drive unit rotates the platen 15 and feeds out the recording paper 9.

As shown in the side views of FIGS. 1 and 2, the side plates 12a, 12b of the main body 13 are
A disc-shaped positioning tool 19 is provided that projects inward of 12b. This positioning tool 19
are provided at two locations each in the depth direction of the side plates 12a and 12b, and their axes are positioned in advance with respect to the axes of the guide shaft 3 and sliding shaft 4 of the recording device 5 described above. When machining to provide 19, it is only necessary to drill around this axis, which allows for highly accurate machining.

Further, this positioning tool 19 is slightly smaller than the diameter in the height direction of the guide groove 18 of the chart mount 10 described above, and substantially matches the diameter in the height direction of the step 18a.

A window hole 20 is formed in the depth direction near the positioning tool 19 of the side plates 12a, 12b.
0, the leaf spring 21 protrudes inward. This leaf spring 21 has a perspective surface at the front and is bent at a right angle at the rear to allow the movement of the chart frame 10 when it moves in the storing direction, and to act as a lock for the chart frame 10 when it moves in the pull-out direction. This is what we do.

Next, the operation of the above-mentioned configuration will be explained.

In order to store the chart mount 10 in the storage section 13a of the main body 13 of the recorder, first, the rear end of the guide groove 18a of the chart mount 10 is inserted into the positioning tool 19 of the main body 13. The plate spring 21 passes through the deep groove 18c while pushing the chart frame 10, but the plate spring 21 allows movement due to the above-mentioned shape at the time of insertion, so the chart frame 10 is further stored. At this time, the guide groove 18 has a slightly smaller diameter than the positioning tool 19, making it easier to store. (Fig. 3a) Next, the step 18a of the guide groove 18 of the chart frame 10 comes into contact with the front positioning tool 19, and the storage is completed. At this time, the chart pedestal 10 is housed with a slight upward deviation due to the step 18a, and is positioned using the height of the platen 15 at this time as a reference. At this time, the leaf spring 21 is locked in the deep groove 18b, and the chart frame 10 is prohibited from moving forward, and is locked in this state. (Fig. 3b) However, in this stored state, the platen 15
The upper recording paper 9 is always properly positioned with respect to the dot 8 of the recording device 5.

In addition, when removing the chart frame 10, the leaf spring 2
When the part 1 passes through the deep grooves 18a and 18c, the plate spring 21 can be pushed outward to release the lock and be taken out.

Further, the conventionally used rails are not used, and the cylindrical positioning tools 19 are only provided at two positions on each side, which reduces costs and reduces friction during sliding.

Furthermore, if the positioning tool 19 is made rotatable, the operation of pulling out and storing the chart frame becomes smooth.

In the above configuration, the left and right leaf springs 21, 2
1 or by changing the recess depth of the left and right guide grooves 18, 18 into which the bent portions of the plate springs 21, 21 are inserted, the chart mount 10 can be adjusted to the actual state when the chart mount 10 is inserted. 13 is pressed against one side plate 12b (or 12a). Thereby, the inner surface of the pressed side plate 12b (or 12a) can be set as the 0 point of the input information signal.

[Effects] As explained above, in the recorder according to the present invention, grooves are provided in the depth direction of the chart mount, and positioning tools are provided at multiple locations in the depth direction of the recorder body.
When the main body of the chart stand is stored, it can be precisely positioned and stored, and the printing of the recording device can be stabilized.
