Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to a motor mounting and power supply device used in a drive mechanism of a tape recorder and the like.

2. Description of the Related Art Conventionally, there is a motor shown in FIG. 1 that is used to rotate, for example, a reel stand, a capstan, etc. of a tape recorder. That is, the brush portion 1a' is provided above and the governor rotor 1b' is provided below to constitute a motor body 1', and the motor body 1' is attached to the chassis 2' by screwing a screw 6' from the bottom surface of the chassis 2'. At the same time, the motor shaft 1c' is rotatably protruded from the bottom surface of the chassis 2,
Moreover, the lead wire 7 for power supply is connected to
As shown in B and C, it was attached to the brush part 1a' side. In this case, since the lead wires 7 were soldered to the motor body 1', the soldering work was time-consuming, and the narrow space made it difficult to handle the lead wires 7 after soldering. Ta. Moreover, since the lead wire 7 is relatively long, electrical noise from the motor body 1' is easily induced into the lead wire 7, which is a drawback.

The present invention was made in view of the above points, and its purpose is to reverse the brush part and governor rotor part from the conventional product, provide the brush part on the side facing the printed circuit board, and By connecting the conductive part protruding from the brush part to the conductive part of the board, the number of lead wires can be reduced, eliminating the need for soldering and handling of the lead wires, and making it less susceptible to electrical noise from the motor. The purpose of this invention is to provide a motor mounting and power supply device that is rarely used.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

Reference numeral 1 designates a motor main body, and within this motor main body 1, a brush portion 1a is provided on the opposite side of a printed circuit board 3 (described later), that is, on the lower side in the drawing, and a governor rotor portion 1b is provided above the brush portion 1a.

2 is a chassis, and 3 is a printed circuit board superposed on the chassis 2. 1c is a motor shaft that rotatably protrudes from the insertion hole 4 between the chassis 2 and the printed circuit board 3; 1d is several terminal parts for power supply protruding from the side of the brush part 1a;
d protrudes from several terminal portions 5 provided on the chassis 2 and the printed circuit board 3 and is connected to the conductive portion 3a of the printed circuit board 3, a so-called wiring pattern, by bending or the like. In this case, the conductive part 3 of the printed circuit board 3
Solder the terminal part a and the terminal part 1d to strengthen the connection. 6 is a screw for mounting the motor,
The attachment of the motor body 1 to the chassis 2 is not limited to screwing.

Since one embodiment of the present invention has the above-described configuration, the motor body 1 is attached to the chassis 2 by screwing using screws 6, as in the conventional product. However, a brush portion 1a is provided on the side facing the chassis 2, and a terminal portion 1d for power supply protruding from the brush portion 1a is provided on the chassis 2 and the printed circuit board 3 superimposed on the chassis 2. After protruding from the insertion hole 5, it is bent and connected to the conductive portion 3a of the printed circuit board 3 by soldering. Then, electricity may be supplied to the motor body 1 via the conductive portion 3a of the printed circuit board 3. In this case, an insulating material 8 is interposed in the insertion hole 5 to prevent a short circuit between the terminal portion 1d and the chassis 2.

As mentioned above, in the present invention, the brush part and the governor rotor part of the motor are reversed from the conventional products, and the brush part is provided on the side facing the chassis, and the brush part protrudes from the conductive part of the printed circuit board superimposed on the chassis. Connect the provided terminals to supply power to the motor body.

Therefore, it is possible to reduce the time and effort involved in soldering the power supply lead wires to the motor body and the time and effort required to process the lead wires after soldering. Furthermore, since the conductive portion of the printed circuit board and the terminal portion of the motor are directly connected over a short distance, the influence of electrical noise is reduced.
