Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape guide device that allows the angle of the tape guide surface to be easily adjusted.

Tape guide devices used in tape recorders and the like are generally cut from metal materials, cut from synthetic leather resin, or molded pole-shaped products.

Incidentally, in order to ensure that the tape runs correctly, the verticality of the tape guide device is often finely adjusted when installed, and for this reason, some tape guide devices are equipped with a complicated adjustment mechanism.

The present invention provides a simple tape guiding device in which the tape guiding surface and the adjusting means are constructed of a single plate-shaped body.One embodiment of the present invention will be described below with reference to the drawings.

First, in FIGS. 1 and 2, reference numeral 1 denotes a tape guide made of a plate-shaped body with spring properties, such as a stainless steel plate or a phosphor bronze plate, and the central part of the guide 1 has an arbitrary radius. It is bent into a U-shape, and the bent portion serves as a guide surface 3 for the tape 2, and mounting portions 4 and 5 are integrally formed at both ends.

The mounting portion 5 of the tape guide 1 is floated upwardly relative to the mounting portion 4 and is shaped differently, so that the mounting portion 4 is mounted in contact with the mounting board 7 with screws 6, while the mounting portion 5 is raised from the mounting board 7, and then screw in the screw 8.
It is installed by

With this configuration, one piece 1a of the tape guide 1 and the other piece 1b are inclined at an angle θ with respect to the mounting board 7, as shown in FIG. If so, the guide surface 3 is inclined by θ/2 with respect to the vertical line of the mounting board 7.

Therefore, by turning the screw 8 and changing θ, the angle of the guide surface 3 changes.In other words, if the screw 8 is turned to the right, the guide surface 3 will be tilted upward, and if the screw 8 is turned to the left, the guide surface 3 will be tilted downward. 3 can be adjusted to obtain the optimum angle of the guide surface 3 for tape running.

Note that the same effect can be obtained even if θ is set to a minus value. Figures 4 and 5
The figure shows another embodiment, which is provided with a guide body 9 into which two pieces 1a and lb of the tape guide body 1 are fitted.

That is, the guide body 9 is formed with two slits 9a, 9b, and the tape guide body 1 is inserted into the slits 9a, 9b.
The two pieces 1a and lb are fitted together, and the guide body 9 is positioned and held by fitting a protrusion 9c provided on the lower end surface into a hole in the mounting board 7.

With this configuration, displacement and deformation of the guide surface 3 of the tape guide body 1 can be prevented, and highly accurate tape guidance can be performed.

As described above, in the present invention, the tape guide surface and the angle adjustment mechanism of the tape guide surface are constructed using a single springy sheet metal, so that the optimum angle for the tape guide surface can be easily obtained. Moreover, since the amount of angular change of the tape guide surface is half of the amount of adjustment, fine adjustment can be easily performed, and the structure is simple, making it inexpensive, and its practicality is excellent.
