Abstract

(57) [Summary] [Purpose] To be able to cut the roll recording paper and start winding it according to the desired recording period. [Structure] A cutting knife having a gentle chevron shape with a cutting edge is used for cutting recording paper, and a winding reel with a groove that rotates at a constant torque is provided for winding.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a recording paper feeding device used for a vertical self-recording meteorometer such as a self-recording thermometer, a self-recording hygrometer, and a self-recording barometer.

[0002]

[Prior art]

 In the past, recording paper of a fixed length was wrapped around a cylindrical drum and fixed, and this cylindrical drum was rotated at a constant speed for recording. Therefore, when the recordable period is fixed and continuous recording beyond that period is required, it is necessary to remember to replace the recording paper at some point, and the recording result is divided into multiple sheets. It also caused the mistake. In addition, there are also those for continuous recording only for long-term recording, using only a roll recording paper feeding mechanism and a winding mechanism. In this case, it was not suitable for short-term recording, and it could not be used when the recording was to be divided for each period.

[0003]

[Problems to be solved by the device]

 This invention is an improvement that enables the recording paper to be cut and rolled up at an arbitrary position by using a roll recording paper, so that continuous recording for an arbitrary recording period can be obtained.

[0004]

[Means for Solving the Problems]

 A cutting knife (1) with a gentle chevron shape and a cutting edge (5) is provided parallel to the sprockets (2) and (2), and the tip of the roll recording paper cut with the cutting knife (1) is used. A take-up reel (4) with a groove (3) to be inserted is provided parallel to the cut knife (1). This proposal has the above configuration.

[0005]

First, the roll recording paper is cut using the cutting knife (1). The cutting line of the cut recording paper is a gentle mountain shape that mirrors the shape of the cutting knife. By inserting this tip into the groove (3) of the take-up reel (4), the take-up starts again.

[0006]

[Examples]

 The present invention will be described with reference to the drawings. (A) Sprocket (2) and (2) are fixed to a rotary shaft to feed a recording paper. (B) Supports (6) are installed near the sprockets (2) and (2) in parallel with each other. The support (6) prevents the recording paper from being lifted from the sprockets (2) and (2). . (C) The cutting knife (1) is fixed to the support (6), and the cutting edge (5) is formed in a bulged shape. (D) The guide (7) is close to the sprockets (2) and (2), and the recording paper that has passed through the gap between the sprockets (2) and (2) and the support (6) is sprockets (2) and (2). It is pulled away from 2) and sent forward. (E) The take-up reel (4) is provided in parallel with the sprockets (2) and (2), and rotates at a constant torque in synchronization with the sprockets (2) and (2), and further torque works. It is supposed to idle. (F) A thin groove (3) is cut in the take-up reel (4) in the axial direction. With the above-mentioned configuration, the following is performed in use. First, pull out the V-shaped roll recording paper from the recording paper compartment, insert the pointed tip inside the support (6), and then insert the sprocket holes (2) above and below the recording paper. ), By turning the sprockets (2), (2) according to the pins of (2), the recording paper is fed along the guide (7) through the inside of the support (6). If the leading edge of this recording paper is placed in the groove (3) of the take-up reel (4), it will be wound on the take-up reel (4) with a constant torque as the sprockets (2) and (2) rotate. Will be taken. When the recording result is required after a certain period of time, turn the take-up reel (4) in the reverse winding direction to return the wound recording paper, and hold the lower end of the recording paper below the cutting knife (1). Cut so that it bends upward from. At this time, the cutting knife (1) has the cutting edge (5) in the shape of a bulge in a chevron shape, so that the cutting portion has the shape of the cutting edge. When recording next time, pull out the leading edge of the recording paper until it touches the take-up reel (4), then rotate the take-up reel (4) and insert the leading edge of the recording paper into the groove (3). For example, after that, the recording paper is wound around the take-up reel (4) with a constant torque as the sprockets (2) and (2) rotate. The leading edge of the recording paper is formed by swelling the cutting edge (1) of the cutting knife (1) into a chevron shape, so that it can be easily slid into the groove (3) of the take-up reel (4).

[0007]

[Effect of device]

 In this way, the recording paper can be cut at any time when necessary and the recording result can be obtained at hand, so that the recording result for an arbitrary period can be obtained. In addition, since the cutting edge of the cutting knife (1) is moved and the central part of the cut recording paper swells into a chevron, this swelled central part can be easily applied to the groove (3) of the take-up reel (4). It can be slid in and the next recording and rewinding will occur. Further, since the gap between the guide (7) and the blade edge (5) of the cutting knife (1) is close enough to allow the recording paper to pass, it is safe because a fingertip or the like does not directly touch the blade edge (5).
