【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 chart loading mechanism, and the other configurations are the same as those of the conventional recorder, so the chart loading mechanism will be mainly described. FIG. 1 shows a plan view (top view) of a main part of the recorder according to the embodiment. In this embodiment, the folded chart W is housed in the chart box 1, and projects the starting W _a chart W from the chart outlet 1a of Chatobo box 1. A guide portion 1b for guiding the chart W is provided adjacent to the chart outlet 1a, and the guide portion 1b is formed by extending a wall forming the chart outlet 1a. In the vicinity of the chart delivery port 1a, the pressure contact roller 2 is rotatably supported while being displaced, and the guide roller 3 is rotatably supported.

In this embodiment, the pressure contact roller 2 is made of, for example, rubber in order to surely grip the chart W, and is present at a position where it comes into contact with a substantially central portion of the chart W in the width direction. The reference roller 3 is connected to a pulse motor (not shown) for delivering the chart W via a suitable number of gears. The pressure roller 2 is connected to the guide roller 3 by the belt 4 and rotates in the same direction as the guide roller 3. Therefore, during the operation of the recorder, the pressure roller 2 also rotates with the rotation of the guide roller 3 due to the rotation of the motor.

A pressing spring plate 5 for pressing the chart W against the guide roller 3 is attached to the guide portion 1b of the chart box 1 with a screw. The pressing spring plate 5 has a restoring force in a direction away from the guide roller 3. Further, the spring plate pressing arm 6 is arranged so as to be swingable in the vicinity of the guide roller 3, and the pressing plate 5 is always attached to the guide roller 3 side against the restoring force by the spring plate pressing arm 6. It is energized. On the front side of the guide roller 3, a chart base 7 that is interlocked with a chart loading push button switch (not shown) is displaceably arranged. That is, by pushing the local portion 7a of the chart base 7 in the direction of the arrow, the switch is turned on along with the displacement of the chart base 7, so that the motor rotates at a higher speed than the normal rotation.

Then, due to the gap between the guide portion 1 b, the guide roller 3 and the spring plate pressing arm 6 (and the spring plate 5), and the gap between the chart base 7 and the pen tip 8, the chart box 1 to the chart base 7 are reached. A delivery path for the chart W is formed. The nib 8 is lightly brought into contact with the chart base 7, and data is recorded on the chart W by the nib 8 on the chart base 7.

Further, the recorded chart W is pressed against the sprocket wheel 12 by the chart pressing member 13 via the chart support plate 11 by the sprocket wheel 12 engaged with the feed hole thereof, and the chart storage box 14 Is configured to be sent to. The diameter of the sprocket wheel 12 is slightly larger than the diameter of the guide roller 3 so that the chart W does not loosen.

Further, as shown in FIG. 2, the pressure contact roller 2, the spring plate pressing arm 6 and the chart base 7 are respectively mounted on a plate 20 swingably attached to a support shaft 10 of the guide roller 3 and screwed. It is fixed at. Therefore, as shown in FIG. 1, if the local portion 7a of the chart base 7 is pushed in the direction of the arrow, the pressure contact roller 2, the spring plate holding arm 6 and the chart base 7 are integrated by the plate 20 around the spindle 10. Move. That is, when the local portion 7a of the chart base 7 moves in the arrow direction, the pressure contact roller 2 pushes against the guide portion 1b of the chart box 1, and the spring plate pressing arm 6 moves in the direction away from the spring plate 5.

The driving force of the sprocket wheel 12 and the guide roller 3 for pulling out the chart W is obtained by a pulse motor, but in this embodiment, the pulse motor rotates at a low speed during the normal time recorded in the chart W and a new chart is loaded. Sometimes it rotates at high speed. That is, as described above, when the chart loading push button switch interlocking with the chart base 7 is turned on, the pulse motor rotates at high speed, and the pressure contact roller 2 and the guide roller 3 both rotate at high speed. As shown in FIG. 3, the chart loading push button switch and the pulse motor have a circuit configuration in which the button switch 30 is connected to the pulse motor 32 via the CPU 31, and the pulse motor 32 is connected only when the button switch 30 is turned on. A pulse signal suitable for high speed driving is generated by the CPU 31.

[0014] On the other hand, the chart W accommodated in the chart box 1, as shown in FIG. 4, starting W _a of that are somewhat longer in than fold chart W, charts W chart box 1 This starting end W _a is positioned at the guide portion 1b of the chart box 1 when the sheet is inserted into the box (see FIG. 1). For this reason, it is important to form a starting end W _a the new chart W. For reference, a normal chart W'is shown in FIG.

In order to load a new chart with the recorder configured as described above, first, the chart W as shown in FIG. 4 is put in the chart box 1. At this time, previously set to a state where start W _a chart W is positioned at the guide portion 1b chart box 1. Then, when the local portion 7a of the chart base 7 is pushed in the direction of the arrow, the chart loading push button switch 30 is turned on, the pulse motor 32 rotates at high speed, and both the guide roller 3 and the pressure contact roller 2 rotate at high speed. Further, when the chart base 7 is pushed, the pressing roller 2 is brought into contact with the guide portion 1b by the plate 20. At the same time, the spring plate pressing arm 6 separates from the spring plate 5, the biasing force of the spring plate 5 is released, and the spring plate 5 separates from the guide roller 3 by its own restoring force. As a result, a gap is formed between the guide roller 3 and the spring plate 5.

Here, when the pressure contact roller 2 is pressed against the guide portion 1b, the start end W of the chart W sandwiched between the pressure contact roller 2 and the guide portion 1b as the pressure contact roller 2 rotates. _a Passes through the gap between the guide roller 3, the spring plate 5 and the spring plate pressing arm 6 and reaches the gap between the chart base 7 and the pen tip 8. At this point, if the pushing of the local portion 7a of the chart base 7 is stopped, the rotation of the motor is returned to the normal speed by the return of the chart base 7, and at the same time, the pressure contact roller 2 and the spring plate pressing arm 6 are returned to their original positions. Returning to the state, the pressure contact roller 2 is separated from the guide portion 1b, and the delivery of the chart W is stopped. At the same time, the chart W is pressed against the guide roller 3 by the spring plate 5 biased toward the guide roller 3 by the spring plate pressing arm 6. After that, the starting point W of the chart W_aIs appropriately pulled out, and after passing through the chart support plate 11, the feed hole of the chart W is hooked on the sprocket wheel 12, whereby the loading of a new chart W is completed.

[0017]

[Effect of device]

 Since the recorder of the present invention is configured as described above, simply by pushing the chart base after putting a new chart in the chart box, the start edge of the new chart is automatically sent to the chart base, which is better than before. The chart can be loaded easily and quickly.
