The first switch lever 20 abuts on the projection 40p of the drive rack rail 40 while being urged clockwise by a switch lever spring (not shown).
Rotate to the position shown in FIG.
2 is open. The right down rail 44 is urged leftward by a down rail lock 48 and a down rail spring (not shown), and is at a position shown in FIG. 15. The shaft 35 b of the right holder guide 35 is connected to the cam 44 d of the right down rail 44. Since it is inserted at the top, the right holder guide 35 is held at the top. The start sensor 24 is on because it receives the light of the LED 56.

The loading operation of the cassette is started by pushing the right driving rack rail 40 or pushing the cassette 30 downward, and the position shown in FIGS. 16 and 21 is reached. 16 and 21, the up rail 47 is in a free state due to the movement of the right drive rack rail 40, and the right holder 32 is rotated counterclockwise by the holder return spring 29, so that the cassette 30 held by the up rail 47 as well. It rotates, and the stopper (not shown) of the right holder guide 35 hits the right holder 32 and is held at the horizontal position.

When the right holder 32 rotates, the lock release lever 34 is urged so that the tip 34a faces inward and is rotatably attached to the right holder 32.
When 2 rises, it is in contact with a cam portion (not shown) of the right holder guide 35, so that the distal end 34a does not protrude inside the right holder 32.

When the right holder 32 rotates and becomes horizontal, the lock release lever 34 does not come into contact with a cam portion (not shown) of the right holder guide 35, so that the tip 34a comes out of the right holder 32. Thus, a lever (not shown) for locking the lid 30a provided on the cassette 30 is pressed, and the lock of the lid 30a is released.

The lid opening holder 39 is used for the holder guide 3
The protrusions 39c and 3c of the lid opening holder 39 are formed by the cam groove 35a of No. 5 and the cam groove (not shown) of the left holder guide 36.
Since 9d is pushed up, the lid opening holder 39 rotates slightly counterclockwise, and the lid 30a of the cassette 30 is also slightly opened by the claw 39e of the lid opening holder 39.

FIGS. 29 to 32 are views for explaining the operations of the lock release lever 34 and the lid opening holder 39 in further detail. FIGS. 29 and 30 are FIGS.
31 and FIG. 32 are plan and side views corresponding to the state of FIG. 21. 30 and 32 also show partial cross-sectional views.

Referring to these figures, when the right holder 32 is inclined, the lid opening holder 39 rotatably engaged with the holder 32 swings together with the right holder 32. The convex portion 39c of the lid opening holder 39 is rotated clockwise in the drawing by the cam portion 35g of the right holder guide 35 (closed state). Lock release lever 34
Of the right holder guide 35
29 and is rotated clockwise in FIG. 29 against the winding spring 63, and the tip 34 a of the lock release lever 34 is pulled into the right holder 32. Thus, the cassette can be smoothly inserted and removed without being caught on the lock release lever 34 when the cassette is inserted or removed.

On the other hand, when the right holder 32 is in the horizontal state, the lid opening holder 39 swings counterclockwise together with the right holder 32. When the lid-opening holder 39 swings, the convex portion 39c of the lid-opening holder 39 is rotated by the cam portion 35f of the right-side holder guide 35 with the right-side holder 32 as a fulcrum. The lid 30a of the cassette 30 is slightly opened.

As described above, when the cassette is loaded, the cassette 30 is horizontally moved to a predetermined position with the cover 30a slightly opened, so that the cassette 30 does not come into contact with each component such as a draw-out roller inside the apparatus. The height required for the movement is lower than that required for horizontal movement with the lid 30a kept closed, thereby making it possible to reduce the height of the device.

The lock release lever 34 also swings with the right holder 32, and the cam portion 35 of the right holder guide 35
e, the other end 34b of the lock release lever 34
Is released, and is urged by the winding spring 63 to rotate in the counterclockwise direction in FIG. 31 so that the tip 34a projects.

Referring again to FIGS. 16 and 21, in this state, the start sensor 24 is on because the start sensor 24 receives the light of the LED 26, but when the right driving rack rail 40 further moves, the LED 56 Light is blocked and the start sensor 24 is turned off. The first switch lever 20 is rotated clockwise by a switch lever spring (not shown) to rotate the first cassette switch 22.
Is closed.

The closed state of the first cassette switch 22 is detected, and the motor 18 is started at a low voltage. The rotation of the motor 18 is transmitted to the pulley 19, the worm gear 16, the worm wheel 12, and the right cam gear 10, and the rotation of the right cam gear 10 is transmitted to the left cam gear 11 through the sync gears 14a and 14b and the main shaft. As a result, the right driving rack rail 40 and the left driving rack rail 41 are moved in the horizontal direction, and moved to the positions shown in FIGS. On the way, the start sensor 24
Is turned off as described above (point A in FIG. 25). The voltage of the motor 18 is switched from low to high by detecting the off point A of the start sensor 24.

17 and 22, when the right driving rack rail 40 moves as shown in FIG.
6 passes through the hole 40q of the driving rack rail 40,
The start sensor 24 is turned on (point B in FIG. 25). A short brake is applied to the motor 18 for a certain period of time when the point B is detected, and then the motor 18 is driven with a low voltage.
The rack 40c of the right drive rack rail 40 is formed to the position shown in FIG. 14, and meshes with the large-diameter gear 10a of the right cam gear 10. The large-diameter gear 10a of the right cam gear 10 also meshes with the rack 44e of the right down rail 44. The guide rail drive shaft 51 implanted on the right guide rail 49 is in contact with the cam 10c of the right cam gear 10.

The cam 10c is shaped so that the horizontal movement amount of the right side drive rack rail 40 by the large diameter gear 10a and the amount of movement of the guide rail drive shaft 51 by the cam 10c are the same. The rotation of the right cam gear 10 causes the large-diameter gear 10a of the right cam gear 10 to move the guide rail drive shaft 51 by the cam 10c while meshing with the rack 44e of the right down rail 44, so that the right drive rack rail 40 moves. The relative position between the down rail 44 and the right driving rack rail 40 remains unchanged in FIG.
8 and the position shown in FIG.

18 and 23, the protrusion 40n of the drive rack rail 40 and the bending 1c of the right frame 1 are shown.
7 (see FIG. 7), and the cam 10c of the right cam gear 10 and the guide rail drive shaft 51 are in contact, so that the position of the right drive rack rail 40 is maintained. When the right cam gear 10 further rotates, the right drive rack rail 40 remains as it is and the right down rail 4
Only 4 moves, and the cam 44c of the right down rail 44 presses the convex portion 37a of the right cassette holding lever 37 attached to the right holder guide 35.

The right cassette holding lever 37 rotates counterclockwise to hold the cassette 30 from above.
When the right down rail 44 further moves, the right holder guide 35 descends because the shaft 35b of the right holder guide 35 is inserted into the cam 44d, and the convex portion 37a of the right cassette holding lever 37 is moved by the cam of the right down rail 44. It moves from 44c to the concave portion 40k of the right driving rack rail 40, and comes down to come in contact with the cassette spring 53. By making the concave portion 37a of the right cassette holding lever 37 contact the cassette spring 53, a double-acting mechanism of the right cassette holding lever 37 is made using the force of the cassette spring 53. Cassette 30
Is lowered by being held by the right cassette holding lever 37, the slider 31, the right holder 32, and the left holder L33.

As described above, the cassette holding lever 37 for pressing the cassette is provided on the cassette holding means, and operates by the movement of the right down rail 44 so that the cassette spring 5
3, the number of parts can be reduced and the configuration can be simplified as compared with a conventional cassette holding lever which is swingably provided between a pair of frames.

The right skate board lock 26, which is rotatably mounted on the right frame 1 and urged clockwise by a skate board lock spring (not shown), contacts the convex portion 26a with the right holder guide 35. Therefore, it is held at the position shown in FIG. When the right holder 35 is lowered, the right skateboard lock 26 rotates clockwise, the leading end enters the recess 40r (see FIG. 14) of the right drive rack rail 40, and the right drive rack rail 40 moves in the ejecting direction. Is locked. Further, when the right holder guide 35 descends, the open lever 60 attached to the mechanical chassis performs an operation of opening the lid opening holder 39 and the lid 30a of the cassette 30.

19 and 24, when the right down rail 44 moves to the position shown in FIG.
d, the right holder guide 35 is further pushed down, and the cassette 30 is positioned by the positioning pins 55a and 55b implanted in the mechanical chassis 55.
The cassette 30 is loaded by being loaded on the end faces of 5a and 55b and the cassette stays 55c and 55d, and the right pressure spring 57 pressing the shaft 35b of the right holder guide 35 downward. At this time, the down rail lock 48 is
As shown in FIG. 5, the tip 48a is pressed against the inclined surface of the concave portion 44g of the right down rail 44 by being urged clockwise by the down rail lock spring (not shown). Rail 44
Will be biased rightward.

As described above, the right down rail 44 is provided with the down rail lock 48 at both ends of the sliding range.
Thus, for example, as shown in FIG. 15 or FIG. 19, the cassette holder is urged leftward or rightward, thereby holding the cassette holder at a predetermined position. This right down rail 44
Is performed by, for example, a down rail spring 58 as shown in FIG. 27 (eject state) and FIG. 28 (cassette loaded state), in the cassette loaded state shown in FIG. The cassette is urged in the direction of raising the cassette (left direction), and the right down rail 44 is moved by vibration or impact, or the right down rail 44 is moved in FIG.
There is a drawback that the load of the down rail spring 58 becomes a load on the motor when moving from 7 to the state of FIG. 28, but according to this embodiment, there is no such drawback.

The down switch lever 52 rotatably attached to the right down rail 44 moves the shaft 52a of the down switch lever 52 into the groove 40h provided in the right drive rack rail 40 by the movement of the right down rail 44.
Rotate along, push the second switch lever 21 and rotate it counterclockwise, the second cassette switch 23 changes from the open state to the closed state (point c in FIG. 25), and a certain period of time when the point C is detected Then, the drive of the motor 18 is stopped, and the loading of the cassette 30 is completed.

The ejection operation is performed in the reverse operation to the above-described loading operation.
, But start with a high voltage. The movement is started from the positions shown in FIGS.
The start sensor 24 is turned on at the position shown in FIG. 21 (point D in FIG. 25), and when this point is detected, the voltage of the motor 18 is dropped from high to low. Thereafter, the cassette 30 comes to the position shown in FIGS. 15 and 20, the cassette 30 is rotated so as to be easily taken out, and the first cassette switch 22 is changed from the closed state to the open state (point E in FIG. 25). After detecting the point E, a voltage is applied to the motor 18 in the ejecting direction at a low voltage for a certain period of time, and the ejecting operation is completed.

Since the left side portion on the opposite side is also driven synchronously by the synchro gears 14a, 14b and the main shaft 13, it is possible to eliminate the up lever 46, the up rail 47 and the down switch lever 52 and the respective switches. Except for this, the operation is the same.
