Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic cassette loading device for a video tape recorder (hereinafter referred to as VTR).

In recent years, there has been a demand for V'r1 and other devices to make effective use of the space above the device body, so a cassette type cassette in which the cassette is inserted from the side, for example from the front, rather than from the top of the device has been introduced. An automatic loading device, a so-called slosh-in type automatic cassette loading device, has been developed.

In such a device, the cassette is provided in the front of the device and is housed in a cassette holder through an insertion slot. When the cassettes are stored, the holder is first conveyed horizontally into the device, then vertically downward, and placed at a predetermined position on the cassette reel stand.

- When taking out 10,000, 10,000 cassettes, and 2 cassettes, the cassette holder is transported directly above the KM, which is the opposite of the above-mentioned loading operation, and then transported horizontally toward the cassette insertion slot.
Transport the cassette to the cassette insertion slot.

By the way, in the above device, it is detected that the cassette is housed in the force+Lg holder to obtain the timing to drive the conveyance means of the cassette holder, and the cassette holder moves from the cassette loading position to the cassette insertion position ( It is necessary to have a means for determining the timing to stop the conveying means of the cassette holder when the cassette holder is conveyed at the cassette removal position) t, and a means for determining the timing to stop the operation of the conveying means when the cassette holder is conveyed to the cassette loading position. It is.

Conventional devices had a configuration in which a detection switch and an operation means for the detection switch were provided for each of the above-mentioned means, which caused problems such as an increase in the manufacturing cost of the device and a complicated configuration.
It was. .

Nine, the cassette slot is generally covered with a door that can be opened and closed to prevent dirt from entering the device. In the conventional device, the door is opened and closed by providing a solenoid to drive Jj+ and a push button to control the on/off pipe of this solenoid, and by pressing this push button, the solenoid is turned on and off. It was done under control.

However, such a configuration requires a solenoid and an electric circuit for driving the solenoid, resulting in problems such as increase in number of devices, increase in device manufacturing costs, and complication of the configuration. Moreover, with this configuration, when inserting a cassette,
The device requires two operations: first, pushing a push button to open the door, and then inserting the cassette into the cassette slot, making the device extremely difficult for the user to use.

Furthermore, in the above-mentioned apparatus, when a cassette is stored in the cassette holder through the cassette insertion port, the cassette holder is generally configured to be automatically transported to the cassette loading position by the transport means. It is. In this case, if the conveyance means is operated immediately after the cassettes and cassettes are stored in the cassette holder, there is a drawback that the user feels as if his or her hand is being sucked into the device.

This invention was made in consideration of the above circumstances, and by simplifying the configuration of the detection switch and its operating part to obtain the timing to control the on/off of the motor O,
The object of the present invention is to provide an automatic cassette loading device which can reduce the manufacturing cost of the device, simplify the configuration, and provide accurate timing output.

Insert the skein through the slot (not shown).

When it is stored in the holder 43, it will be in the state shown in FIG. Figure 8 shows relay lever 1, the details of which will be described later, compared to Figure 4.
The difference is that 43 etc. started the operation. When the cassette 14 is stored in the cassette holder 43, the motor
(see figure) starts rotating. This motor llo rotational torque is belt C1a warm ear 111f! It is transmitted to the output gears IaL and 71tlt via the drive gear 69' which rotates in conjunction with the ohm wheel #9. As a result, the first output gear FOR rotates in the direction of arrow a1 in the figure, and the ninth output gear FIL rotates in the direction of arrow a in the figure. (depending on the rotation of the engine) Crank 12L.

411 rotates to move the cassette holder 4J vertically downward. In this way, the cassette 14 is finally placed at a predetermined position fcl! on the reel stand (not shown)! FIG. 8 shows the state 11 in which the cassette holder 41 is placed in the car kv) loading position in this way. The motor 6# stops rotating when the cassette 14 is placed in a predetermined position on the reel stand. .

In addition to tTh, a-ra ##L, and j#R, there is a roller 51L.

Since JIIl is also moved along the groove, the posture of the cassette holder 4J is maintained in the horizontal position 11 even when the cassette holder 4J is moved vertically.

With the above explanation, there are nine skeins, and there are 9 skeins to complete the installation.

As mentioned above, the stroke length of the holder 43 is obtained by rotating the output gears ``roL'' and ``rono''. ・When the cassette holder 4J is at the cassette insertion position of 10 cassettes and the 7 loading position, Pin FJL on both ends.

7JL (or vxn, vsR) is set so that the shaft 15L (or 15R) of the output gear 10L (To or FOR) does not exist directly above. for example,

Here, the means for obtaining the timing to control the on/off tW of the motor 6e, which is a feature of this invention, will be mainly explained in Fig. 6.
This will be explained with reference to FIG. 9 and FIG. 1O.

A switch lever IJ is rotatably supported on the top plate 5# via a shaft 81 in the direction of the arrow (ay→as) shown in the figure. This switch lever 82 has a cam driving part IJ driven by a cam, which will be described later, and a switch operating part 84, which operates a detection switch, which will be described later. The cam drive unit IS is located on the upper surface side of the output gear ton, and a downwardly protruding #5 is provided at the tip of the cam drive unit IS.
A concave cam 8C is formed on the upper surface Ka of the output gear yoRo. The cam surface 11 of this cam 86 is connected to the output gear 'l0RO.
It has a nine-arc shape centered on the axis vimYt, and a cassette insertion detecting section #1 and a cassette loading detecting section 89 are formed in a part thereof with a distance of approximately 180' from the circumference of the output gear l0RO axis. Each detection portion a'j, J# is formed to protrude toward the center of the output gear FOR;
The protruding tip portion is formed in an arc shape centered on the output ear FARO axis viR.

In switch operation group 14, a detection switch 90 is provided which is controlled to be turned on or off by being operated by the O switch operation section 84. Further, the switch lever 82 is always urged in the direction of the arrow (al) shown in the figure by a return spring 91, so that the pin 85 comes into contact with the cam surface of the cam 86.

The operation tube in the above configuration will be explained. Cassette holder 4
3 is in the cassette insertion detection position, the pin 15 of the switch lever 8j is engaged with the cassette insertion detection part 18 of the cam 86, and the switch 90 is operated by the switch operation part 84 and is in the on state. When the switch 9- is in the ON state, the motor 66 does not rotate. From this state, the cassette holder JJK cassette y) y4t- is inserted, and the cassette 14 moves to the protrusions is, si (fifth
When the skein ) 74 is further pushed in even if it comes into contact with the holder (see figure), the output gear 101 is slightly rotated in the direction of the arrow (a) due to this pushing force.
is removed from the cassette insertion detection section 1# of the cam #-, and the tele A-11 is rotated in the direction of the arrow (a?) shown in the figure by the return spring 91. Therefore, when the switch #O is turned off, the motor 66 rotates and the car 41! v) Holder 43
At the cassette loading position, the first cassette 14 is placed at a predetermined position on the reel stand. At this time, the 1st output gear Fo
R rotates by JIF and the pin 85 of the Switch Reno 4-82 rides on the cassette loading detection section 89 of the life*a cam att, so the switch 9o is turned on and the switch motor 6#
rotation stops.

From this state, when the cassette eject button is pressed to remove the cassette, the motor is driven by the motor drive circuit and rotates tIII even though the switch tO is on. start As a result, Sui,
Zen 15 of Chire Δ-82 comes off from cassette loading detection part 8#, switch #O goes to OFF state, and MO! #-The cassette holder 41 continues to rotate, and when the cassette holder 41 reaches the cassette insertion position, the pin 1j is inserted into the cassette insertion detection section 1a.
Since the motor 66 is raised to K'11F), the switch #O is turned on and the motor 66 stops rotating.

According to the above configuration, one cassette is stored in one cassette holder 43.
4 is stored, and the motor 511 is rotated, and when the cassette holder "-43" containing the 1 cassette 14 is conveyed from the cassette insertion position to the cassette insertion position, the rotation of the mormelo 6 is stopped. A detection switch and its operating means for obtaining the timing t, and a detection switch and its operation for detecting that the cassette r4 is stored and the cassette holder 43 has been conveyed to the cassette insertion position and stopping the rotation of the motor 66. Since the detection switch 90 and the operation means can be used in common, the manufacturing cost of the device can be reduced.

Since the configuration controls whether the detection switch #0 is turned on or off depending on the rotational position of the motor #6, it is necessary to ensure that the motor ## is turned on or off when the cassette 14 is positioned at a predetermined position. #Io The mechanism for transmitting the rotational torque tube output gear FoRK is mainly shown in Fig. 11(a).

111 will be explained with reference to Figures 1111 and 13.
As shown in 11 gll(a), 载), the worm wheel #- that meshes with the worm ear #1 and the drive gear #9' that meshes with the output ear r# blade are connected by a toe and a panel 102. .

That is, as shown in line 1211, the lower end NK of the drive ear ##' that meshes with the output ear FoR has a protrusion 1#J formed thereon and meshes with the worm gear #1. Protrusion 1a4 and strike v/# 1 # on the upper end surface of ohm wheel #-
J is so cute. In this way, the two ears #m and ##' are placed on the axis, and Δne 1e.
Since they are combined coaxially with aYt interposed, one end is the protrusion of the gear 1111, and the other end is the worm wheel g#05If! A1a4FCm fixed@re,
W and ip' are urged to rotate in opposite directions, but this rotation is restricted by the contact between protrusions J#J and J414. In addition, fix the worm wheel #6 and set the gear
When the projection lOJ is rotated against the elastic force of 1 in the arrow direction (aρ direction, the protrusion lOJ rotates until it reaches the wΔ101 position and 1 step) Drop/# When it reaches the 10ir position, the protrusion @101 strikes. The rotation is regulated by coming into contact with. The operation in the above configuration will be explained. Before inserting the cassette 74 into the cassette holder 41fIC, 1 worm wheel σ-9! @1114 and drive gear 6#' protrusion 1tl

Even if IYC comes in contact with the car, F 4F is pushed in. Due to the force of this push, the crank FIL is in a raw state.

The output ear 10 rotates in the direction of the arrow (al) shown in the diagram through the FIR pipe, and the gear 10 is engaged with the output ear RAM.
1 is a toshi, which resists the elastic force of the panel 101 and moves as shown by the arrow (
a$) direction and the protrusion 1ex-pg@ki1114
move away from The cassette insertion detection s#1 of the cam 8- of the output gear FIR (see Figure 9) indicates that the protrusion 1o3 is at the stroke 1.
The setting is such that the pin 85 is removed from the cassette insertion detection sag immediately before contacting the f-10J, and the detection switch #0 is turned off. While pushing in the cassette 14, the motor #C starts g@tN. The rotation of this motor CC is immediately transmitted to the worm wheel #-, and the tone becomes worm wheel 1#.

If you release this insertion during the 4O insertion and it is round, unless the detection switch #O is turned off,
If the worm wheel C# does not rotate in the direction of the arrow (a-) shown in the figure, if the cassette 14 is released, the gear 1111 is pushed back to the position where the loz still contacts the protrusion 104 by the elastic force of the instrument panel 1020. 9. If the detection switch IIa does not close for some reason even though the cassette 14 is inserted, the gear 101 should rotate only to the position where the protrusion xox is still in contact with the stodino e-J#J. Since the cassette 74 is pushed inside the device and cannot be taken out, it is important to eliminate the problem. In addition, the
The dC does not rotate immediately after the detection switch and switch are turned off, but rotates after a certain period of time has elapsed. To explain this using FIGS. 14 and 15, the cassette r4 is stored in the cassette holder 4J,
When the detection switch -0 that obtains the output of the motor C6 is turned off, the first switch is turned off. fFJ(a)
The pace potential of %ψ′7 transistor Q1 is resistor R1,
It gradually decreases according to the time constant of condenser CI (first
1 (b4a, female) - Transistor QB is turned off, and the power output voltage of Jinuta QsaQm becomes high level as shown in Fig. 1F (d)], motor #- starts. - Sea detection switch S-W is set to 1 For example, from the time when ``OR'' to the time when 鵠-y-l turns on, it is set to about 100 ugly I. According to the above configuration, the insertion force of the cassette 14 is determined only by the insertion force of the cassette 14 and the elastic force of the panel 101. Ru. The elastic force of this torsion Δ$JOJ should be enough force to insert seven cassettes into the cassette holder 4a when it is desired to stop the insertion of the cassette r4 in the middle of insertion. However, it is not necessary to use such a large amount of force, and with this configuration, the cassette can be inserted with a small force.

(9) After the cassette 14 is stored in the cassette holder 43, the cassette holder 4J is not transported immediately, but after a certain period of time has passed after the actual company switch #0 is turned off (-6C is rotated). 1 The rotational torque is transmitted to the output gear FOL.F#R by the action of the worm gear 9 and drive gear 6#' with a delay in time, and the cassette holder 41 is transported. The first reason is to prevent the feeling of hands being sucked into the device.

Next, we will mainly explain the drive mechanism of the opening/closing door that is installed in the cassette insertion slot so that it can be opened and closed freely. Figure 9.

It! This will be explained with reference to FIG.

A concave cam 110 is formed on the upper surface of the output ear FOLD. This cam J J old is formed so that its outer peripheral surface is curved toward the center of the output gear reLO and faces each other.

The door drive unit 111.111 and the open state holding unit 111 whose outer circumferential surface is formed in an arc shape centered on the axis F#Lt of the output gear rOL and are opposed to each other J J * J
It consists of 14 parts. ixi#i This is a swinging cam lever driven by this cam 11#.In other words, this swinging force A-111 is freely movable in the direction of the arrow (a y 44g,) shown in the figure through the shaft 1111 @. The shaft is supported by a shaft, and one end thereof is extended to the upper surface side of the output shaft 10L.
Its tip IIK is provided and the bin 11F simulates the cam wtcm of the cam 1oo.This allows the swinging cam lever z

It is rotated in the direction. This swing cam lever J J I
(t) A cam slider 111 is connected to the other end. The cam slider Ill is attached to the top plate 111c so as to be slidable in the front-rear direction (in the direction of the arrow (AT axis & arrow) in the drawing). It was provided standing up at the rear end.

The protrusion xxttlli moving cam lever 111Kflj is formed and connected to the swinging cam lever 111 so as to be sandwiched from both sides by two protrusions III and 111.

At both front ends 11 of the top plate 5J, supports [JJJL, JJJl] are provided vertically downward to support the opening/closing door 122. The opening/closing door 122 is provided on the upper part of the support plates 111L and 111B, and the support plate JJJ is attached from the 6tt good shafts 114L and 114RK

It is set so that it extends to the center of the support plate JjJX4DF#3 side through l1llt. The door lever 115 is connected to the cam slider 118 by a protrusion 121 that is notched upwardly from the lower end of the cam slider 111 and engaged by a notch 130. In front of the door lever 111, its protrusion 1ja is the opening/closing door 1.
22 and is connected to the opening/closing door 121). In addition,
A projection 114 is provided in the hole 132 provided above the elongated hole JJ1.
L is inserted.Also, the door Δ-125 is always urged in the direction of the arrow (ate) shown in the figure by the animal 14 NEJJJK.

The operation in the above configuration will be explained. Before inserting the cassette and when the cassette is installed in a predetermined position, the door i+-1zl is centered on the axis 116t and is moved by the spring 111 to ) direction K11m1+11, the opening/closing door 111 is rotated in the direction of the arrow (a) shown in the figure, and the cassette and tray insertion holes are closed. When the cassette 14 is inserted from the ζO state, the opening/closing door 122 opens.
The cassette 14 is pushed to the front of the cassette F4 and rotates in the direction of the arrow (ml) shown in the figure, so the cassette insertion slot opens and the cassette 14
is stored in the cassette holder 4J. When the door is closed, the slider 111 moves backward in the direction of the arrow shown (illustrated). Also, this is K> Swing cam lever 115
moves in the direction of the arrow (-ma) shown in the figure, and the bin JJF leaves the cam surface of the cam l1tj.The cassette 14 is stored in the cassette holder 4J, the 1 motor C- starts rotating, and the output gear 1oL moves in the direction of the arrow (as) shown in the figure. ) direction Kll - the bottle 111 rides on the open state holding part 111 of the cam 11 - ) raises 0 In the case of the device shown - as mentioned above, the force my) F4
When the output gear "FaLIFaR" rotates slightly once, the motor d6 rotates when the output gear FIL is pushed in. When driven, the cam J J at
) Maintain open state @11 j is located near the female ring 111. Therefore, the output gear FoL is set to 8i by the motor 5-.
When driven, the bin 111 immediately raises the Kji state holding unit JJJK, and the opening/closing door 111 company cam J J OK
The bullet hits the circular lI. ζO This means that before the entire six-layer set is completely inserted into the 1m interior, the KM opening/closing door 1
Since this means that the cassette 14 can be completely cleaned, it is possible to prevent the generation of unpleasant frictional noises and damage to the cassette due to the friction generated between the cassette 14 and the opening/closing door.

When the motor 1g rotates and the output gear flOL rotates in the trench near the cow rotation, the door drive 112 J
! You will be guided at As a result, the swing cam lever 115
gradually moves Kg in the direction of the arrow (a-) shown in the figure, and the opening/closing door 122
is the direction to close the cassette insertion slot,
) direction. Then, when the output gear FOL rotates half a turn, the bin 111 rotates around the shaft FI of the output ear FIL.
When the cassette insertion slot (V) is removed from the ζO state closest to L and the cassette insertion slot is completely closed, the bin JJF is guided by the half slope of the remaining half of the door drive unit 112 and opens and closes. The door 122 gradually opens, and -1
While the cassette 11 is being guided to the open state holding @J J 4, the rear surface of the cassette 14 is sent out to the outside of the device. After this, the bin 11F passes through the door drive unit 111 of the cam 110, but as mentioned above, the rear side of the cassette 14 has already come out of the device, so the opening/closing door 111 does not close, and the output gear F6L - If the motor # stops after completing half a rotation, the cam J will be in the state shown in Figure 9. By pulling out the cassette),
The opening/closing door 122 will close naturally.

According to the above configuration, since the opening/closing operation of the opening/closing door 112 is performed simultaneously with the loading and unloading operations of the cassette 14, there is no need to open/close the opening/closing operation of the opening/closing door 122, and the cassette y4
Item o*: The removal operation becomes easier. In addition, there is no need to provide a solenoid or the like to open and close the door 122, so sI!
This will result in a reduction of one point.

Next, Fig. W44, Fig. 5, and Figs.
This will be explained with reference to FIGS. 7, 8, and 17. At the outer upper end of the left side plate j4L of the cassette holder 4J,
One end of the cassette detection lever 141 is rotatably supported via a shaft 142t in the direction of the arrow (a4+a1) shown in the figure.

A relay lever 143 is provided at the outer lower end of the support plate 44L and is rotatably supported on the shaft 4# in the direction of the arrow (as"ate) in the figure.
At the end of the cassette insertion port, there is a protruding piece 14 that protrudes downward.
A connecting spring 141 is tensioned between this cassette insertion port side end and the cassette insertion port side end of the cassette detection lever 141. The relay lever 14M is biased in the direction of the arrow (ale) shown in the figure by a relay lever spring 14gK whose one end is fixed to the support plate 44L. In this case, the elastic force of the connection Δ spring 1450 is set to be greater than the elastic force of the relay lever spring 14g.
, When the cassette holder JJ in which the cassette or cassette is not stored correctly or the cassette holder 4J in which the cassette is not stored tries to move backwards, the relay/
4-J 4 It has a function of preventing this movement by engaging with the protruding piece 144 of 4J. 141 will be described in detail later, but when the cassette is in the predetermined position tVca, it comes into contact with the relay lever 14s and forcibly rotates it in the direction of the arrow (ax) in the figure, thereby causing the multi-connection spring 145 to By generating a force to rotate the cassette detection lever 141t in the direction of the arrow (-so) shown in the figure, the cassette 14' can be reliably loaded onto the reel stand (not shown). .

(v) The free end portion C of the detection lever 141 is integrally formed with a cassette presser 14# as shown in Fig. 5 and Fig. 1. This skein.

The presser foot 149 has a notch 111at formed in a substantially arc shape downward from the upper end of the side plate 5dL of the cassette holder 43.
It is positioned in the interior 11 of the cassette holder 43 through the cassette holder 43. If the detection lever 1411d, the cassette, and the holder are not inserted into such a car that presses the cassette 141f@, the relay lever spring 14- causes the arrow shown (-*-
) direction and is locked at the lower end of the notch 150. In the above configuration, when the cassette 14 is inserted in the correct posture into the cassette holder 43 at the working cassette insertion position described in the operating tube. , the cassette presser 14g is lifted by the diagonal force at the upper part of the front surface of the cassette), so the cassette detection lever 141 moves around the shaft 142 in the direction shown by the arrow (a).
Rotate in the direction. This causes the relay lever 143 to move to the shaft d#.
Kit is moved in the direction of arrow (a-) with Ll as the center. This state mt is shown in FIG.

In this state, the protrusion 144 of the relay lever 141 is stopped.
When the motor 66 rotates, the cassette holder 41 is transported to the cassette loading position, and the cassette is loaded at a predetermined position on the reel stand. At this time, the relay lever 148 comes into close contact with the pedestal 14# and is rotated about the shaft 49L in the direction of the arrow (11.) shown in the figure. When the cassette is detected, the cassette 1110 is rotated in the direction of the arrow (11.) via the connecting spring 145t. Therefore, the cassette 1 pusher 149 presses the cassette 7/4f against the reel stand side], and it is possible to prevent the cassette placed at a predetermined position on the reel stand from wobbling. 14 is not inserted into the cassette holder 47 in the correct posture - Since the cassette detection lever 141 does not rotate, the relay d-143 also does not rotate. Therefore, the protrusion 144 of the relay lever 141 is struck
Since the cassette holder 4J is caught in the 4-141, the cassette holder 4J cannot be conveyed, so the switch/chiller 84 does not rotate and the motor 66 does not start.

According to the above configuration, the relay lever 143 for inserting the cassette holder 74 is driven by the cassette detection lever 141 for detecting that the cassette 14 is inserted into the cassette holder 41 in an accurate posture. , it is possible to reliably prevent movement of the cassette holder 43 in which no cassette 14 is housed.

In addition to the cassette detection function, the cassette detection lever 141 also has the function of driving the relay lever 143 as described above, and the relay lever x4i has the function of opening the cassette holder 41 and driving the cassette presser 149. Since it has a functional configuration, it is possible to reduce the number of parts in the device.

In addition, what are the racks 61L and 61B shown in Figure @6?
It is also possible to form it integrally with L and JJR. good,
The present invention can be implemented in cassette automatic loading devices other than the straight-in type automatic cassette loading device.
