In such a conventional recorder, the recording paper feeding mechanism, in which the feeding stock 21, the recording drum 22, the storage stock 23, etc. are integrated, is rotated to be attached to and detached from the main body. When downsizing the
It is necessary to construct the recording paper feeding mechanism so that these members are housed within a predetermined radius of rotation, that is, a distance a between the rotational fulcrum 41 shown in FIG. 3 and the outermost edge of the recording paper feeding mechanism. When a folded recording paper with a folding width is used as the recording paper 31, for example, both the feeding stock 21 and the storage stock 23 must have a width of at least b. In view of this and to ensure smooth conveyance of the recording paper 31, the actual configuration of this type of device is a third
As shown in the figure, the feeding stock 21 is placed on the recording drum 2.
2, and the storage stock 23 is formed at a position angularly shifted by about 90 degrees from the feeding stock 21 with the recording drum 22 as the center.

Therefore, in such an apparatus, the recording pen 51 that slides on the recording drum 22 to perform recording, its sliding mechanism, etc. must be provided above the recording paper feeding mechanism.

When a recorder is used by being incorporated into a measurement system device, for example, it may be necessary to keep its height within a predetermined dimension, but in such conventional configurations, it is difficult to make the height compact. had extremely difficult drawbacks due to its structure.

This invention was developed in view of this point, and it is possible to make the device more compact in the height direction by effectively utilizing the empty space in the lower left part of the main body shown in FIG. The purpose is to provide a recorder that can.

[Means for solving problems]

Therefore, in the present invention, the feeding stock is rotatably attached to the recording paper feeding mechanism so that it can be accommodated within a predetermined turning radius of the recording paper feeding mechanism, and a main body support for the feeding stock is provided at a predetermined position on the main body. A member for guiding the position is provided.

[Effect]

With this configuration, for example, when the recording paper is inserted into the main body by a predetermined angle, the feeding stock is latched to a guide member provided at a predetermined position of the main body, and in subsequent operations, this feeding stock is stopped. The stock is regulated by this guide member and positioned at a predetermined position on the main body. Therefore, unlike conventional devices, there is no need to position the feed stock near the recording drum, and an empty space can be created near the recording drum. It is possible to arrange a sliding part of a recording mechanism such as a recording pen in this empty space, and it is possible to make the size in the height direction compact.
