Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a typewriter having a paper guide that uses a leaf spring to provide a click feeling while ensuring reliable positioning.

Conventional Structure and Problems When inserting type paper, it is important to position a paper guide for guiding the edge of the type paper depending on the size of the type paper to be inserted.

Conventional paper guides are positioned by surface-to-surface contact and friction. As a result, the dimensions may vary, burrs may appear, making it stiff and difficult to move, and as you use it, it may become less slippery and may move accidentally and the insertion position may shift without you knowing. .

Purpose of the invention The present invention solves these problems and aims to provide a typewriter that can be easily positioned with a click feeling and that can secure the position once it is positioned.

Structure of the invention The present invention includes a paper support in which comb teeth are continuously arranged in the longitudinal direction of the back surface, and
By providing a leaf spring having a protrusion at the apex of an angular shape on a leg of a paper guide that is slidable in the same direction as the arrangement direction of the comb teeth and protrudes through a notch provided in the paper support. To provide an excellent typewriter which allows reliable positioning when sliding the paper guide in the longitudinal direction and provides a pleasant click feeling when sliding.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a typewriter in one embodiment of the present invention.

In FIG. 1, 1 is a cabinet of the typewriter body, 2 is a platen knob for feeding paper 3, and 4 is a keyboard. 5 is a paper guide as shown in FIG. 2, which has a guide portion 5a;
It has legs 5b and 5c. Reference numeral 6 denotes a paper support for supporting the paper 3, which has a notch 6a in the longitudinal direction, and continuous comb teeth 6b as shown in FIG. 3 are provided on the back surface by narrowing the notch 6a. As shown in FIG. 4, the legs 5b and 5c of the paper guide 5 are inserted into the notches 6b, and the chevron-shaped plate springs 7 are engaged with the legs 5b and 5c. That is, as shown in FIG. 5, the leaf spring 7 has notches 7a and 7b that engage with the legs 5b and 5c of the paper guide 5, and also has bent portions 7c and 7d. The leaf spring 7 is provided with a protrusion 7e that comes into contact with the comb teeth 6b.

In the above configuration, the paper guide 5
When the paper is slid according to the size of the type paper 3, the protrusion 7e of the leaf spring 7 feels a click and elastically moves over the comb teeth 6b of the paper support 6 between the teeth at the desired position. Securely lock at the (valley). In addition, the notches 7a and 7b of the leaf spring 7 and the bent portions 7c and 7d are
Since the respective positions are different from each other in the direction of the arrow A and the direction of the arrow B, the plate springs 7 are reliably engaged with the legs 5b and 5c.

Effects of the invention As described above, the invention allows the plate spring to be easily attached to the paper guide without using screws, etc., and allows the round protrusions of the plate spring to ride over the comb teeth carved into the paper support. Since it fits in the valley, it allows for reliable positioning with a pleasant click feeling when moving, and its practical effects are great.
