Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recorder used in an underwater object detection device such as a fish finder. In these recorders, a feeding woodwind and a winding woodwind are arranged on the back side of a plane determined by a paper hanging member, for example, a paper hanging roller and a paper feeding roller, and a record is drawn at an appropriate place on the paper hanging roller side as it is fed out from the feeding woodwind. The recording paper is stretched and held between a paper hanging roller and a paper feeding roller, and the paper feeding roller is rotated to sequentially move the recording paper and wind it up on a winding woodwind. This invention is
In particular, the unwinding woodwind or the winding woodwind can be taken out or inserted from the recording observation side, and therefore it is easy to insert or set the recording paper into the unwinding woodwind or the winding woodwind, or to remove the recording paper from the winding woodwind. The present invention relates to a recording device that can hold a recording plate located below a recording sheet without making slight movements.

Many underwater object detection devices use a method that receives reflected ultrasonic waves and records continuous underwater cross-sectional images on recording paper, but the recording paper is automatically re-rolled after recording. Many have mechanisms. Generally, in this type of recorder, the recording paper is stretched over almost the entire surface of the recorder, as shown in Figure 1, in order to make it possible to observe the underwater cross-sectional image drawn on the paper over as wide a range as possible. However, it is customary to store the wound woodwind on the back side. Therefore, both unused recording paper and recorded recording paper are stored on the back side of the recorder, so when replacing the recorder, raise the recorder and fold the edges of the paper into the back, front, and rear sides. It had to be rotated around the ship, which was troublesome and required some skill, especially when replacing it on a shaky ship.

This invention provides a recorder that can eliminate the above-mentioned drawbacks by moving only the recording plate so that the unwinding woodwind or the winding woodwind can be taken out or inserted and installed from the recording observation side. It is.

FIG. 1 shows a perspective view of a conventional apparatus, and FIG. 2 shows an explanatory view of a cross section of the recorder shown in FIG. 1, viewed from the direction of arrow A.

In FIG. 1 or 2, an unused recording paper 1 is fed out to the back side of a recording plate 2 and rotatably supported by a woodwind 10, and the leading edge of the recording paper 3 is fed through the surface of the recording plate 2 as shown in the figure. The woodwind 11 is fed out at a constant speed by the roller 4 and wound up again on the back side of the recording plate 2.
It is wound up.

In this case, as described above, the recorded underwater image is designed to be displayed as widely as possible, so both the unused recording paper 1 and the winding woodwind 11 are stored on the back side of the recording plate 2 and cannot be seen from the direction of arrow B. It is normal not to have one. Therefore, when replacing the recording paper, raise the entire recording device 6 and insert the new recording paper 1 from the back side.
Attach the end of the paper to the paper hanging roller 7 and belt 8.
It is necessary to take the paper through a complicated path such as bringing it out to the surface through the gap between the sheets, pulling it out onto the recording board 2, guiding it to the back side again through the gap between the paper feed roller 4 and presser roller 9, and winding it around the winding woodwind 11. Not only was this not an easy task to do on a ship, but it also caused meandering paper feed and poor winding.

FIG. 3 shows an explanatory diagram of one embodiment of the present invention, and FIG. 4 shows an explanatory diagram showing the state of the embodiment shown in FIG. 3 when the recording paper is replaced.

In FIG. 3 or 4, the recording plate is composed of 41 and 42 made of approximately equal length, and one end of the recording plate 41 has a paper hanging roller 7, and one end of the recording plate 42 has a paper feeding roller 7. A roller 4 is rotatably attached. A gear 43 is fixed to the other end of the recording plate 41, and a holding fitting 40 that rotatably holds the payout woodwind 10 on which the recording paper 3 is attached is attached to the recording plate 41 so as to be positioned at a proper position on the back side. . Further, a handle 19 is attached to a suitable position on the recording plate 41, and the other end of the recording plate 41 is formed into a U-shape 45 having an appropriate dimensional ratio. Recording board 4
A gear 44 is fixed to the other end of the recording plate 2, and a holding fitting 40 for rotatably holding a winding woodwind 11 for winding up the recording paper 3 is attached to the back surface of the recording plate. Further, the other end of the recording plate 42 forms an extension portion 46 that comes into contact with the U-shape 45 of the recording plate 41 as shown. The gears 43 and 44 are rotatably supported inside one of the two side plates 12, 12 forming both sides of the frame of the recorder, and are arranged so as to mesh with each other. The paper feed roller 4 is rotated at a constant speed by a drive source (not shown), and the winding woodwind 11 is simultaneously driven in the direction of the arrow. The presser roller 9 is rotatably supported at both ends by arms 26, 26,
By the action of a spring 27 having an appropriate tension, the paper is brought into contact with the paper feeding roller 4 while maintaining an appropriate contact pressure at all times during the paper feeding state. A belt 8 to which a recording pen is fixed is stretched between two pulleys and rotated. The recording paper 3 is fed out from the feeding woodwind 10, passed through the paper hanging roller 7, the surface of the recording board, and the paper feeding roller 4, and then sent to the winding woodwind 11.
is wound up.

In Figure 3, when this recorder is operated,
After the underwater situation is drawn by a recording pen on the recording paper 3 fed out from the feeding woodwind 10, the paper is sequentially fed by the action of the paper feed roller 4 and the presser roller 9, and is wound onto the winding woodwind 11.

When you finish using the unused recording paper 1 after a long period of use and want to replace the recording paper, hold the handle 19 provided on the recording plate 41 and pull it up, and the gear 43,
44 is rotated in the direction of the arrow as shown in FIG. 4, and the recording plate 42 is also raised at the same time. Therefore, as shown in the figure, the recording paper can be replaced very easily by simply operating the user's hand in the directions of arrows H and H'. When the record plate 41 is pushed down using the handle 19 after the record exchange operation is completed, the gears 43 and 44 rotate in conjunction with this operation, and the record plate 42 is also pushed down at the same time, preparing for operation as shown in FIG. set to state. In this case, if the driven side recording plate 42 is held in the state shown in FIG. 3 only by the rotation of the gears 43 and 44, it will move slightly by the backlash of the gears 43 and 44. Therefore, the present invention has an effect that at the end of rotation of the gear 43, the end of the U-shape 45 provided on the recording plate 41 comes into contact with the back surface of the extension part 46 of the recording plate 42, thereby constantly pressing the recording plate 42 downward. This is to reliably eliminate slight movement of the recording plate 42 due to vibration or the like.

As described above, according to the present invention, the recording paper 3 wound around the winding woodwind 11 located below the recording board and the feeding woodwind 10 are exposed by the action of simply pulling up the handle 19 when replacing the recording paper. This makes it extremely easy to perform a series of recording paper replacement operations, such as removing used recording paper and inserting unused recording paper into both wood pipes, and eliminates the micro-tremor phenomenon that tends to occur in interlocking opening/closing mechanisms. can be definitely excluded.

In the above description, the recording plates 41 and 42 have been described as plate-shaped structures, but they are not limited to plate-shaped structures, and the same effect can be obtained with other shapes such as frame bodies or U-shaped structures. Can be done. Further, although the case has been described in which the handle 19 is attached to the recording plate 41, the handle 19 may be attached to the recording plate 42 depending on restrictions on the arrangement of surrounding structures. In that case, the U-shape 45 may be provided at the end of the recording plate 42 and the extension portion 46 may be provided at the end of the recording plate 41.

Note that instead of the paper roller used in the above embodiment, it is also possible to use a flat plate suitably bent to have a curved surface.
