Description

[Detailed description of the invention] The present invention relates to a mechanism fixing device that prevents parts from becoming defective due to shocks such as dropping during transportation of a tape recorder, that is, a car stereo, which is installed in a car. be.

This type of car stereo is equipped with a movable cassette holder, and when the cassette is inserted into the cassette holder, the cassette holder moves with the cassette to the playing position, and at the same time the pinch roller comes into pressure contact with the capstan. The pinch roller is separated from the capstan by pressing the tape high speed operation lever.

Therefore, when transporting such a car stereo, the cassette holder should be in the non-playing position and the pinch roller should be separated from the capstan. If the pinch roller is accidentally transferred from the non-performance position to the performance position, the pinch roller will be in pressure contact with the capstan, and if the pinch roller is transported while being in pressure contact with the capstan, the pinch roller will be deformed and the packaging will be damaged. When I play the tape after opening it and installing it in my car, I get a wow sound.
This is not desirable because it causes flutter.

The present invention has been proposed in view of these points, and embodiments shown in the drawings will be described below.

Reference numeral 1 designates a cassette holder that is movable up and down between a non-performance position and a performance position using a horizontal support shaft 3 on a chassis 2 as a fulcrum, and allows a cassette (not shown) to be inserted from the direction of the arrow in the non-performance position. do. Reference numeral 4 denotes a suction lever having a claw piece 4a for locking the reel hub of a cassette inserted into the cassette holder 1. In order to move along the horizontal support shaft 3, an arm portion 4b is inserted through the support shaft 3. There is. The suction lever 4
A rack parallel to the support shaft 3 is formed on the arm portion 4b, and the rack meshes with the pinion gear 5. A suction spring 6 is connected to the pinion gear 5, and after the cassette is manually inserted for a certain stroke, the suction lever 4 is sucked by the force of the suction spring 6 to suck the cassette for the remaining stroke. It is composed of

The cassette holder 1 moves from the non-playing position to the playing position after the cassette is sucked, and since its construction is well known, a detailed explanation will be omitted.

Reference numerals 7 and 8 denote a capstan and a pinch roller disposed on the chassis 2, and the pinch roller 8 moves forward or backward together with a magnetic head (not shown).

That is, the pinch roller 8 moves forward so as to come into pressure contact with the capstan 7 in response to the movement of the cassette holder 1 to the performance position, and its structure is well known and is therefore omitted from the drawing. Reference numeral 9 denotes a tape high speed (fast feed) operation lever supported by a supporting protrusion 2' fixed to the chassis 2 and movable in the cassette insertion direction. Always in the non-operating position (protruding position) by the spring 10 suspended in the
is assisted by.

The tape high speed operation lever 9 is connected so as to separate the pinch roller 8 which is in pressure contact with the capstan 7 during the pressing operation from the capstan 7, and the connection mechanism is well known and is therefore omitted from the drawing.

The mechanism of the car stereo, which is the premise of the device of the present invention, is constructed as described above, and this mechanism is housed in the case 11.

Therefore, in the present invention, a through hole 12 is formed in the case 11, and a locking hole 13 is formed in the tape high speed operation lever 9, the vertical positions of which substantially match when the tape high speed operation lever 9 is pressed, and the tape high speed operation lever 9 is formed during transportation. is in a pressed state so that the through hole 12 and the locking hole 13 are substantially aligned, and in this state, the stopper piece 14 is inserted into these holes 12 and 13 from above to maintain the pressed state of the tape high speed operation lever 9. It is something.

Therefore, the pinch roller 8 can be forcibly held apart from the capstan 7 by the pressed state of the tape high speed operation lever 9.

The stopper piece 14 has a seat plate portion 14' that is joined to the surface of the case 11, as shown in FIG.
Fixation can be achieved by screwing the mounting screw 16 into the screw hole 15 formed in the case 11 through the through hole 14'' formed in the seat plate portion 14'. The caution sheet 17 is pasted.

Incidentally, if the caution sheet 17 is attached to the upper surface of the seat plate portion 14' of the stopper piece 14 as shown in FIG. 3, the mounting screw 16 can be made unnecessary.

As mentioned above, the device of the present invention is configured such that the tape high speed operation lever in the mechanism housed in the case is fixedly held in the pressed operation state by the stopper piece. The pinch roller can be forcibly held apart from the capstan by the pressing operation, and even if the cassette holder is accidentally moved to the playing position due to shock during transportation, the pinch roller will be pressed against the capstan. This eliminates the concern that the pinch roller may be deformed during transportation, which is useful in practice.

Claims (1)

[Scope of utility model registration request] It is equipped with a movable cassette holder, and when a cassette is inserted into the cassette holder, the cassette holder moves to the playing position with the cassette, and at the same time the pinch roller comes into pressure contact with the capstan, and in this state, the tape high speed control lever is pressed. In a tape recorder in which a mechanism of the type that separates the pinch roller from the capstan by pressing the capstan is housed in the case, a through hole is formed in the case and the mechanism for separating the pinch roller from the capstan by the pressing operation is provided in the tape high speed operation lever. Locking holes are formed whose vertical positions approximately match, and when the through-hole and the locking hole are approximately aligned during transportation, stopper pieces are inserted into these holes and the tape high-speed operation lever is pressed. A mechanism fixing device for a tape recorder that holds the pinch roller in a state separated from the capstan.
