Abstract

PURPOSE:To reduce the number of parts and to make it enough to compose the parts in a reduced space as well by moving a head cleaning roller in making use of the movement of a tape guide. CONSTITUTION:When the tape guide 2 is moved, a rotary drum 1 is commenced to rotate, and when the tape guide 2 is further moved up into a certain position, the tape guide 2 is brought into contact with one end 24 of a supporting arm 21, and this end 24 is pushed out of a locus of the tape guide. By this motion, the cleaning roller 3 at the other end of the arm 21 is brought into contact with the rotary drum 1. Furthermore, when the tape guide is moved to come into a loading completion position, the arm 21 is restored to its original state by a spring 22, and hence the cleaning roller 3 is separated from the rotary drum 1. By this method, since an arm 21 to be operated by the movement of the tape guide 2 is utilized for an operation mechanism of the head cleaning roller 3, the number of parts can be reduced, while the space can also be reduced.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operating mechanism of a head cleaning roller in a magnetic recording/reproducing device. [Prior Art] Fig. 2 shows the operating mechanism of a conventional head cleaning roller. In the figure, (1) is a rotating drum, (2 is a
) is the tape guide, (3) is the cleaning roller, (4
) is a support arm for the cleaning roller (hereinafter referred to as arm), (5) is a spring for pressing the cleaning roller against the rotating drum, (6) is a cam for moving arm (4), and (7) is a tape guide. (2) stopper, (8)
is a pin press-fitted into the cam (6) to move the arm (4), and (9) is the pivot portion of the arm (4).

Next, the operation will be explained. The rotating drum (1) starts rotating when the tape guide (2) starts moving. Further, the cam (6) rotates in synchronization with the movement of the tape guide (2) (see FIG. 2(a)!).

Thus, while the tape guide (2) is moving (see Figure 2(b)), the roller (3) is moved by the spring (5) to the rotating drum (1).
) is pressed. The mechanism was such that when the tape guide (2) came to the position where loading was completed (see FIG. 2(C)), the roller (3) could be removed from the rotating drum (1) again.

[Problems to be Solved by the Invention] The conventional head cleaning roller operating mechanism uses a dedicated cam (6) to operate as described above, which increases the number of parts and takes up space. There were problems such as restrictions on the arrangement and configuration of the system.

This invention was made in order to solve the above-mentioned problems, and it is possible to reduce the number of parts and create a head cleaning roller operating mechanism that can minimize the space required by using the movement of the tape guide. The purpose is to obtain.

[Means for Solving the Problems] The operating mechanism of the head cleaning roller according to the present invention utilizes the movement of the tape guide, and moves the roller so that the rotating drum and the cleaning roller come into contact with each other at a certain position during the movement of the tape guide. It is equipped with a support arm.

[Function] The operating mechanism of the head cleaning roller according to the present invention utilizes an arm that is operated by the movement of the tape guide, so the number of parts can be reduced and space can be reduced.

[Example] An example of the present invention is shown in FIG. 1 below. In Fig. 1, (1), (2), (3), and (7) are the same as the conventional one, (21) is the cleaning roller support arm, and (22) is the support arm (21) that is pulled out. (23) is a stopper that regulates the position of the support arm (21), (24) is one end of the support arm (21), (23) is a stopper that regulates the position of the support arm (21);
5) is a pivot portion of the support arm (21).

Next, the operation will be explained. When the tape guide (2) moves, the rotating drum (1) starts rotating. Figure 1 (a)
), when the tape guide (2) moves to a certain position, the tape guide (2) contacts one end (24) of the roller support arm (21), and this end (24) is out of the track of the tape guide. pushed out. This action causes the cleaning roller (3) at the other end of the arm (21) to come into contact with the rotating drum (1) (see FIG. 1(b)). When the tape guide (2) moves further and reaches the loading completion position, the arm (21) returns to its original state due to the spring (22), and the cleaning roller (3) is removed from the rotating drum (1). (See Figure 1(c)).

[Effects of the Invention] As described above, according to the present invention, since the head cleaning roller is configured to operate by utilizing the movement of the tape guide, the number of parts can be reduced, and the parts configuration can also take up less space. There is.

FIG. 1 is a diagram showing the operating mechanism of a head cleaning roller according to an embodiment of the present invention, and FIG. 2 is a diagram showing the operating mechanism of a conventional head cleaning roller. In the figure, (1) is a rotating drum, (2) is a tape guide, (3) is a head cleaning roller, (4) is an arm, (5) is a spring, (6) is a cam, (7) is a stopper,
(8) is a bottle, (21) is an arm, (22) is a spring, (
23) is a stopper, and (24) is one end. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Claims] (1) A rotating drum having a plurality of magnetic heads is provided, a tape running system is provided in which a magnetic tape is wound around the drum at a certain wrapping angle, and the magnetic tape is wound around the rotating drum.
