Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recorder for recording a measurement signal on recording paper according to various input signals supplied from the outside, and more particularly to a recorder characterized by its recording paper feeding mechanism.

[0002]

[Prior art]

 Generally, a recorder includes a recording paper feeding mechanism that moves the recording paper at a constant speed. FIG. 4 shows a sectional view of a main part of a recording paper feeding mechanism according to a conventional example. This mechanism is arranged close to the sprocket wheel 20 that engages with the hole of the recording paper (not shown) and the recording paper supply side of this sprocket wheel 20, and when recording with the recording pen 23, the recording paper is The recording paper support base 21 that supports the recording paper is disposed near the recording paper discharge side of the sprocket wheel 20, and a guide that guides the recording paper sent by the sprocket wheel 20 so as to be stored in the recording paper storage unit 24. And 22. Further, a recording paper retainer 25 is provided opposite to the sprocket wheel 20 and the guide 22 so as to prevent the recording paper from floating above the sprocket wheel 20.

As shown in FIG. 5, in the sprocket wheel 20, a pair of sprocket wheels 20 a and 20 b rotate integrally with the platen 26, and the sprocket wheels 20 a and 20 b engage with holes in the recording paper. However, the recording paper is wound around one part of the platen 26 and sent.

[0004]

[Problems to be solved by the device]

 However, in the recording paper feeding mechanism as described above, since there is a gap a between the sprocket wheel 20 and the guide 22, the recording paper fed by the sprocket wheel 20 may be caught in the gap a. In order to eliminate this, it is necessary to make the clearance a as small as possible, but in consideration of the effects of eccentricity of the shaft and bearing of the sprocket wheel 20, the platen 26, etc., during the assembly of the recorder. Since the clearance management must be performed, the work efficiency of assembly is poor.

Therefore, an object of the present invention is to provide a recorder which does not require a high degree of clearance management and in which the recording paper is not caught in the clearance.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the recorder of the present invention is provided with a sprocket wheel that engages with a hole in the recording paper, and is arranged close to the upstream side of the recording paper of the sprocket wheel to support the recording paper during recording. And a guide for guiding the recording paper so that the recording paper sent by the sprocket wheel is stored in the recording paper storage section. In a recorder equipped with a recording paper feeding mechanism, guide the recording paper continuously from the recording paper support base to the guide, except for the portion facing the sprocket wheel. It is characterized by being connected together.

[0007]

[Action]

 In the recording paper feeding mechanism of the recorder of the present invention, the recording paper support base and the guide are integrally connected except at the portion facing the sprocket wheel. That is, the recording paper support base and the guide are continuous, and the continuous portion connecting the recording paper support base and the guide acts as a platen.

Therefore, there is no gap between the sprocket wheel and the guide, and the recording paper sent by the sprocket wheel is reliably accommodated in the recording paper accommodation section by the guide. This eliminates the problem of recording paper getting caught in the gap, and eliminates the need for gap management, which requires high precision during assembly, and improves assembly work efficiency.

【Example】

 Hereinafter, the recorder of the present invention will be described based on embodiments. However, the recorder of the present invention is characterized by the recording paper feed mechanism, and the other configurations are the same as those of the conventional recorder, so the description will focus on the recording paper feed mechanism. FIG. 1 shows an external perspective view of the main part of a recording meter equipped with a recording paper feed mechanism according to this embodiment, and FIG. 2 shows a cross-sectional view of the main part of the recording paper feed mechanism. This mechanism includes a sprocket wheel 10 that engages with a hole in a recording paper (not shown), a recording paper support base 11 that supports the recording paper when recording with the recording pen 13, and a recording paper sent by the sprocket wheel 10. Is similar to the conventional mechanism in that it is provided with a guide 12 for guiding the recording paper so that it is stored in the recording paper storage portion 14. Similarly, a recording paper presser 15 for pressing the recording paper so as not to lift the recording paper from the sprocket wheel 10 is provided opposite to the sprocket wheel 10 and the guide 12.

The feature of this mechanism is that the recording paper support 11 and the guide 12 are integrally connected. The recording paper support base 11 and the guide 12 are connected by an arcuate portion 19, and here, the recording paper support base 11, the guide 12 and the arcuate portion 19 are integrally molded. The arcuate portion 19 is curved with a curvature similar to the curvature of the sprocket wheel 10, and as shown in FIG. 3, the portions facing the pair of sprocket wheels 10a, 10b are notches 19a, 19b. The rotation of the sprocket wheels 10a and 10b is not obstructed by the arcuate portion 19.

As shown in FIG. 3, in this embodiment, in the sprocket wheel 10, a pair of sprocket wheels 10 a and 10 b are integrally rotated by a shaft 18 instead of a platen. That is, the shaft 18 merely rotates inside the arcuate portion 19, does not have a platen function, and the arcuate portion 19 functions as a platen.

In the recording paper feeding mechanism configured as described above, since the recording paper support 11 and the guide 12 are continuous by the arcuate portion 19, there is no gap between the sprocket wheel 10 and the guide 12. The recording paper sent by the sprocket wheel 10 is not caught in the gap, and the recording paper is surely stored in the recording paper storage portion 14 by the guide 12. Moreover, it is not necessary to perform sophisticated clearance management at the time of assembly, which facilitates the assembly work and does not need to consider the influence of eccentricity in the processing of the sprocket wheel 10, the shaft 18, the bearing, and the like.

In the above embodiment, the recording paper support 10, the guide 12 and the arcuate portion 19 are integrally formed. However, these parts are individually manufactured and connected together at the time of assembly. You may use.

[0014]

[Effect of device]

 As described above, in the recorder of the present invention, the recording paper support base and the guide are continuously guided from the recording paper support base to the guide except for the portion facing the sprocket wheel. Since there is no gap between the sprocket wheel and the guide, the recording paper sent by the sprocket wheel will not be caught in the gap. Further, since there is no gap, it is not necessary to manage the gap highly at the time of assembling, and the assembling work efficiency is improved.
