Abstract

PURPOSE:To reduce the vibrations of a cassette tape recorder by reducing the vibrations generated by a motor by means of the first and second damping members and, at the same time, bringing the second damping member into contact with a printed board in the vicinity of the part where the vibrations are enlarged. CONSTITUTION:This cassette tape recorder is provided with a motor angle member 2 which holds a motor 1, printed board 4 mounted on a cassette tape mechanism main body 3 provided with the motor angle member 2, and the first damping member 5 which is put between the motor 1 and member 2. In addition, the second damping member 6 which is put between the motor 1 and member 2 at a position farther than the first member 5 from the main body 3 and, at the same time, brought into contact with the board 4 is also provided. Thus the vibrations produced by a small-sized thin-thickness motor are reduced by means of the second damping member and printed board after the vibrations are once damped by means of the first and second damping members. Therefore, the vibrations of the small-sized thin-thickness motor can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cassette tape recorder.

BACKGROUND OF THE INVENTION As shown in FIG. 6, the conventional structure was to simply provide a damping member interposed between the motor and the motor angle member to reduce the vibrations of the motor. That is, a motor 9 for driving the cassette tape mechanism main body 3 on the motor angle member 2 held by the cassette tape mechanism main body 3 was attached to the first vibration damping member 6 by a screw 8.

Problems to be Solved by the Invention However, in the conventional configuration, as the cassette tape recorder becomes smaller and thinner, it is necessary to install a smaller and thinner motor, and as a result of the thinner structure, vibrations from the motor increase. There were drawbacks. An object of the present invention is to reduce vibrations from the motor when a small and thin motor is used, and to suppress vibrations of the entire cassette tape recorder.

Means for Solving the Problems The present invention provides a method for holding a small and thin motor in order to prevent vibrations from the motor from being transmitted as vibrations to the entire device when a small and thin motor is used. A cassette tape mechanism body including a motor ampoule member and the motor angle member, a printed circuit board attached to the cassette tape mechanism body, the small and thin motor and the motor angle member, and a first vibration damping member interposed between the small and thin motor and the motor angle member at a position distant from the cassette tape mechanism main body, and at least the position of the first vibration damping member is also a distance from the cassette tape mechanism body; It consists of a second damping member that comes into contact with the damping member.

Effect: The vibration generated from the small and thin motor is absorbed by the first and second motors.
The second vibration damping member reduces the vibration and further expands the vibration.
The vibration damping member and the printed circuit board reduce the vibration of the small and thin motor.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

1 to 3 are diagrams showing one embodiment of the present invention.

As shown in FIGS. 1 to 3, a small and thin motor 1, a motor angle member 2 that holds the small and thin motor 1, and a cassette tape mechanism main body 3 equipped with this motor angle member 2. Printed circuit board 4 to be mounted
and the small and thin motor 1 and motor angle member 2.
and a first vibration damping member 6 interposed between the small and thin motor 1 and the motor angle member 2 at a position further away from the cassette tape mechanism main body 3 than the position of the first vibration damping member 6. intervening and said printed circuit board 4
The small and thin motor 1 is held by a pinwheel 8. FIG. 4 shows the entire cassette tape recorder according to an embodiment of the present invention, and 3a is the cassette tape mechanism main body 3.
10 is a belt interposed between a flywheel 3b provided in the cassette tape mechanism main body 3 and a motor pulley 1a provided in the small and thin motor 1.
It is a cassette tape attached to.

A casing member 11 encloses the entire cassette tape recorder.

Effects of the Invention According to the present invention, the vibration generated by the small f) T5 motor 1 is reduced by the first vibration damping member 6 and the second vibration damping member 6, and the vibration is amplified in the vicinity. Since the 20th vibration damping member 6 further comes into contact with the printed circuit board 4 at the position of the second vibration damping member 6, the vibration is reduced and the cassette tape recorder can be made thinner, which is a great effect. It is something.
