Description

[Detailed description of the invention] This invention relates to a recording paper support structure for fish finders and the like.

Conventionally, recording paper for displaying records in fish finders, acoustic sounders, course recorders, etc. has been produced by supporting a recording paper supply roll on a shaft provided inside the case body, and feeding the pulled recording paper. Mounting was carried out by winding it between predetermined rolls and then hooking it onto a take-up roll.

However, with the above devices, as the device becomes smaller, the recording paper winding path becomes extremely narrow, and it is troublesome to manually wind the recording paper onto each roll one by one. The drawback was that it was very troublesome and difficult to carry out the above work on board the ship.

In order to eliminate these drawbacks, as shown in Figure 1, on the back side of the front transparent cover A of the fish finder, etc.
After the recording paper support plates B are arranged side by side and the recording paper C is inserted between the support plates B and the transparent lid A, the supply roll C and the winding roll C ₂ can be mounted on the back side of the support plate B. The following measures have been proposed and implemented. When changing the recording paper, the mounting part was pulled out of the case by opening the entire front cover, so it was not easy to change the recording paper.
When loading the recording paper, the recording paper C must first be inserted into the narrow gap between the front transparent cover A and the support plate B, which makes it difficult to carry out the work when it is dark, such as at night. There was a problem.

In view of the above, this invention was devised for the purpose of providing a recording paper support structure for fish finders, etc., which allows the recording paper to be replaced quickly and easily. and a substrate that removably supports the supply roll and take-up roll of the recording paper on the back side is supported at the back side of the transparent lid of the case body, and separately from the transparent lid so that it can fall to the front side. This is a characteristic feature.

Next, this invention will be explained using examples.

FIG. 2 is a perspective view showing the developed state of the embodiment of this invention, FIG. 3 is a side sectional view of the embodiment, and FIG. 4 is an explanatory diagram showing the mounted state of the embodiment.

The recording paper support structure of this invention for fish finders, etc.
A substrate 1 having shaft supports 1C, 1C for removably supporting the recording paper 2 along the front surface 1A and the supply roll 2A and take-up roll 2B of the recording paper 2 on the back surface 1B is opened and closed by the front lid 3A of the case body 3. Separately from the transparent lid 4, it is supported so as to be able to fall toward the front side (arrow P) at the rear position of the transparent lid 4 that is attached to the transparent lid 4.

As shown in FIG. 5, the shaft support 1C of the substrate 1 has the cores 2A' of the recording paper rolls 2A and 2B on the side surface of the plate 6 which is biased in the upright direction by the elastic body 5.
2B', and by tilting the plate body 6 in the direction of the arrow Q, the rolls 2A, 2
B can be attached and detached. In addition, substrate 1
The transparent lid 4 is equipped with a hinge or the like so that it can be tipped over vertically when it opens sideways as shown in the figure, and it can be tipped over sideways when the transparent lid 4 is opened vertically (not shown). Supported.

It should be noted that the transmission device (not shown) for feeding out the recording paper 2 is designed so that it can directly engage or fit with the take-up roll or the surface of the recording paper by appropriate means when the substrate 1 is set in a predetermined position. is being used.

When replacing the recording paper 2 using the recording paper support structure according to this invention, first, the recording paper 2 is rewound from the recording paper take-up roll 2A, and after being wound once or twice around the take-up roll 2B, the fourth recording paper 2 is replaced. As shown in the figure, place the recording paper 2 on the front side 1A of the substrate 1, and wrap the substrate 1 in the direction of the arrow R.
Each roll 2A, 2B is pivotally supported at a predetermined position, and then the substrate 1 is raised up and the transparent lid 4 on the front is closed.

In the above embodiment, the board 1 is made to be able to fall down using a hinge, but it may be made to be able to be pulled out using a link mechanism 8 as shown in FIG.

This idea is structured as above, so
When replacing the recording paper, the recording paper can be set by applying the recording paper 2 to the board 1 that has been pulled out to the outside, so the operation is very simple and the replacement work can be done quickly. . Furthermore, when replacing the device, only the transparent cover provided on the front cover of the case needs to be opened, which has various practical effects such as miniaturization of the device.
