Abstract

PURPOSE:To simplify a constitution, to ensure cassette loading operation and to improve the reliability for a cassette loading mechanism, by moving a cassette holder by opening/closing a front door to operate a double speed mechanism. CONSTITUTION:A cassette is put into a cassette holder 7, and a front door 14 is turned counterclockwise while stretching a spring 16. Thus a rotary arm 11 is also turned by a driving pin 15 loose fitted into a slit 13, and a cassette holder 7 is guided by pins 9 and 10 loose fitted into guide holes 3 and 4 of a chassis 1 and shifted to the left by a pin 8. Then the pin 8 is put into a guide hole 2. In this case, the holder 7 is accelerated double and moved faster than the door 14. Furthermore the holder 7 goes down along the holes 3 and 4 after moving to the left. A hook member 5 is turned clockwise by a pin 10 while stretching a spring 6. When the pin 10 passes through a hook part, the pin 10 is locked to hold the holder 7 at the cassette loading position. At the same time, the door 14 is closed.

Currently, the front insertion type is the mainstream due to its superiority in operability, functionality, and design. However, with the front-insertion type, mechanical reasons make it impossible to manually pull in and push down the cassette, so this operation was performed using power from a built-in motor. Therefore, a motor for cassette loading and a sensor for control.

1 and 2 are side views showing one embodiment of the cassette p-ding mechanism of the present invention. FIG. 1 shows the relationship among the chassis, cassette holder, and rotating arm, and FIG. 2 shows the chassis, The relationship between the rotating arm and the front door is shown. Note that the same diagrams are used on the opposite side, with 1 being the chassis, 2, 3, and so on. and 4 (an L-shaped guide hole provided in the main chassis 1; 5 is a locking member that is pivotally supported on the chassis 1, and is connected to the chassis 1 so that the retaining part faces the guide hole 4; It is biased by a tensioned spring 6. 7 is a cassette holder, 8, 9. and 1o are pins provided in the cassette holder 7, which are loosely fitted into the guide holes 1, 3° and 4.
A cassette holder 1 is supported on a chassis 1. 11 is a rotating arm 4 whose one end is pivotally supported at a point P on the chassis 1, and the other end is a long hole 12 into which the bottle 8 is loosely fitted.
A long hole 13 is provided in the central part. Reference numeral 14 denotes a front door of the chassis IVc whose side surface is pivotally supported at a point Q. A drive pin 15 is provided which loosely fits into the elongated hole 13, and a spring 16 tensioned between the chassis 1 and the front door opens the door in the opening direction. energized. Therefore, the rotating arm 11 is pivotally supported at a point P on the outside of the chassis 1, and the side surface of the front door 14 is at a point on the outside. K means that it is pivoted at K. Since the cassette boulder 7I1glji [#7-4111 and the front door 14 are connected by the pin 81 drive bin 15,
The rotating arm 11 rotates beyond the rotation angle of the front door 14, thereby forming a double speed mechanism for moving the cassette holder 1. How many times the rotation angle of the rotation member 11 should be compared to the rotation angle of the front door 14 is determined by the point Q at the rotation center of the front door 14.
It can be determined by the length from P to the drive bin 15 and the ratio of the length from the rotation center point P of the rotation 7-m 11 to the drive bin 15 to the length to the bin 8.

In order to perform cassette loading, the cassette is inserted into the cassette holder 7 shown in FIG. 1, and when the front door 14 shown in FIG. Since the pin 15 also rotates, the rotating arm 11 also rotates. At this time, since the bin 8 is loosely fitted into the elongated hole 12, the cassette holder 7 is guided by the pin 9.10 loosely fitted into the guide hole 3.4 of the chassis 1, and is moved to the left by the rotating arm 11. Move. Then, the bottle 8 enters the guide hole 2 as shown in FIG. 3 (IL). At this time, the cassette holder 1 moves faster than the front door 14 due to the aforementioned double speed mechanism. Further, when the front door 14 is rotated, the cassette holder T moves to the left and then descends along the guide hole 3.4, and the bin 10 is moved to the locking member 5.
The locking member 5 presses the engaging portion of the spring 6.
Rotate clockwise while extending. And bottle 1
0 passes through the engaging portion 3m-f', the locking member 5 rotates counterclockwise by the biasing force of the spring 6, locking the bottle 10 and holding the cassette holder T at the cassette mounting position. , the front door 14 is closed as shown in FIG. 3(b),
Cassette loading is complete.
