Abstract

PURPOSE:To maintain simply the balancing by providing a slant face in downward and outward direction from a tip of a fixed receiving part of a housing so as to prevent a twist or the like when an EP record disk at the lowest position is fallen by its tare weight from the fixed receiving part while being kicked by a push plate. CONSTITUTION:The slant face 14 in downward and outward direction is provided at the lower side of an end part 13 of the fixed receiving part 2 of the housing 1' and a slant face 17 in downward and inward direction is provided to a part with which a center hole ridge 16 of an EP record disk is pressed into contact when the EP record disk 12a is shifted in parallel by the push plate 3 and fallen by its tare weight at the lower side of a keeper 4. After the EP record disk 12a is shifted in parallel by the push plate 3 and a center hole ridge 15 of an EP record disk exceeds an end part 13 of the fixed receiving part 2, the EP record disk is subjected to free fall descent so that the center hole ridge 15 of the EP record disk moves along the slant face 14. In this case, the center hole ridge 16 of the EP record disk in opposite side is pressed into contact with the slant face 17 while being regulated onto the slant face 14 together with EP record disks 12b, 12c whose balancing is maintained by external balancing maintaining devices 5, 5'. Thus, the EP record disk 12a during free fall descent is prevented from being twisted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a record changer that records a plurality of EPs.
The record discs are loaded and the EP records are automatically dropped onto the turntable one by one (this is related to the IP record adapter device).

Conventional configuration and its problems An example of a conventional adapter device is shown in FIG.

In Figure 1, 1 is a housing that can be divided into two parts, and is inserted into the center hole of an HP record.

Reference numeral 2 denotes a fixed receiving part for receiving a record, which is provided on a part of the side surface of the housing 1. The push plate 3 moves under the force of the movement of the upper end 11 of the record feeder 6, moves the lowest record 12.1 among the stacked records 12 in the direction of the arrow mark, and moves it onto the turntable (Fig. (not shown) Fall upwards 3 Stir. Record feeder 6 moves in the direction of arrow B around a fulcrum 1Q provided on N spindle 7, and serves to transmit external horizontal driving force received at lower end 9 from upper end 11 to push plate 3.

b, 12c to prevent lateral slippage. The record presser 6 and the record receiver 6' are external balance maintaining devices for keeping the record 12 in balance.

In such a conventional HP record adapter device, the instant the area around the center hole of the record at the bottom 'l' comes off the fixed receiver 2, the VC of the right side of the record in Figure 1 drops sharply. The periphery of the center hole on that side hits the side surface of the housing 1, causing it to tilt. For this reason, there is a drawback that the equilibrium state cannot be maintained sufficiently during the falling operation.

In addition, a generally used adapter device that does not require an external balance maintenance device has a receiving part that receives the area around the center hole of the record at two or more places from below, and one that holds the record.
There are some that have a mechanism that has a feeding device that drops records one by one, but in those, all of the receivers are movable receivers, and all the movable receivers are housed in the housing at the same time. This is a method of dropping. For this reason, this type of adapter device has a complicated mechanism.In particular, it has a movable receiving part that receives one record at the lowest position, so it is possible to store multiple receiving parts at the same time) and store the record disc in the housing. If the hold is not released, the record will tilt and fall onto the turntable, and in order to time this, advanced assembly processing technology is required to ensure dimensional accuracy of each part. It was.

-1 In any conventional adapter device,
It is difficult to maintain the balance of an EP record during operation, and in order to avoid this, the mechanism has to be large and complicated, and high dimensional accuracy is required.

Purpose of the Invention The present invention eliminates these conventional drawbacks, and provides an excellent EP 6-page record adapter that has a simple structure and can maintain the balance of an EP record while falling under its own weight. It provides equipment.

Structure of the Invention The EP record adapter device of the present invention is provided with an inclined surface downward and outward from the tip of the fixed receiving part of the housing. This prevents twisting when it falls under its own weight from the fixed receiving part, and makes it easy to maintain balance.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. Note that in FIGS. 2 and 3, parts that are substantially the same as those in the prior art are designated by the same reference numerals as in FIG. 1, and explanations thereof will be omitted.

As is clear from FIG. 2, in this embodiment, a downwardly outwardly inclined surface 14 is provided on the lower side of the end 13 of the fixed receiving part 2 of the housing 1'. A downwardly inwardly inclined surface 17 is provided at a portion where the center hole 16 of the EP record comes into contact when the record 12& is moved in parallel by the push plate 3 and falls under its own weight.

If you do this on page 6, the push plate 3 will release the EP record 12.
& moves in parallel, and when the EP record center hole edge 16 crosses the end 13 of the fixed receiving part 2, the EP record center hole edge 16 falls along the slope 14 under its own weight. At this time, the center hole edge 16 of the EP record disk on the opposite side hits the inclined surface 17 while being regulated by the EP record disks 12b, 12c and the inclined surface 14 whose balance is maintained by the external balance maintaining device 5.5'. come into contact with The state of the EP lading board 12a at that time is 12a' (indicated by a broken line in the figure). In this way, since the periphery of the center hole of the EP record disc 12a falls under its own weight while being guided by the inclined surfaces 14 and 17, it is possible to prevent the EP record disc 12& from twisting while falling under its own weight. Therefore, with a simple structure, EP record 1
2a can be caused to fall under its own weight in an equilibrium state.

Furthermore, as shown in FIG.
Underneath, in addition to the fixed receiving part 2, an auxiliary plate 1 is loosely fixed to the push plate 3 with a shaft 20, and rotates around the shaft 21.
A movable receiver 18 that is loosely fixed by a VC shaft 22 and moves in parallel in conjunction with the movement of the page 7 push plate 3 is provided, and the EP record 12 is balanced on both the fixed receiver 2 and the movable receiver 18. It may also be held at In this case, when the push plate 3 moves the EP record disc 12a in parallel in the direction of the arrow in FIG.
& falls along the slope 14 under its own weight. Then, before and after that, the movable receiving part 1 is linked to the movement of the push plate 3.
8 and the EP record center hole edge 16 move in parallel,
Eventually, the EP record center hole edge 16 comes into contact with the inclined surface 17 provided between the keeper 4 and the movable receiving part 18, and the upward movement of the record center hole edge 16 is stopped by the lower end of the keeper 4. It will be done. Then, when the movable receiving part 18 continues to move in parallel and is almost completely accommodated in the housing 1, E
The center hole edge 16 of the P-record disc is disengaged from the movable receiving part 18 and falls under its own weight. When the state at that time is shown in FIG. 3, the movable receiving part 1B becomes like 18' (indicated by a broken line), and the FP
The record 12a is - like 12&' (shown with a broken line).
&ru. At this time, the EP records 12b and 12c are kept in equilibrium by the push plate 3 and the keeper 4, and
The P record disc 12& can maintain an equilibrium state by being restricted by the inclined surfaces 14 and 17, thereby preventing it from twisting while falling under its own weight. Further, when the movable receiving portion 18 is provided as in this embodiment, the external balance maintaining device that has been used in the past becomes unnecessary, and the entire device can be downsized.

At the same time, when the push plate 3 causes the EP record center hole edge 15 to exceed the end 13 of the fixed receiver 2 and start falling under its own weight along the inclined surface 14, the movable receiver 18 moves inside the housing 1. The timing at which the center hole edge 16 of the EP record moves away from the movable receiving part 18 and starts to fall under its own weight along the slope 17 is determined so that the guiding effect of the slope 14. It is desirable that the timing at which the center hole edge 16 starts falling under its own weight is made slightly earlier than the timing at which the EP record center hole edge 16 starts falling under its own weight. In addition, in the case of the above-mentioned actual 9 page flow side, the cross-sectional shape of the sloped surfaces 14.17 is made straight, but the cross-sectional shape of the sloped surfaces 14.17 provided on both sides of the housing 1 is made into a wavy or arched shape other than a straight line. It goes without saying that the timing of the fall may be regulated.

In addition, we can adjust the timing between the push plate 3 and the movable receiver 18, adjust the holding difference of the EP record in the relationship between the fixed receiver 2 and the movable receiver 18, and select the inclination angle and cross-sectional shape of the inclined surface 14. If etc. are carried out appropriately, substantially the same effect can be obtained even without providing the inclined surface 17.

Effects of the Invention As described above, according to the IP record adapter device of the present invention, when a KP record is dropped under its own weight and mounted on a turntable, the housing is formed with an inclined surface, thereby preventing the KP record from falling under its own weight. It is possible to maintain the equilibrium state of the IP record disc, and it also greatly reduces the difficulties of conventional HP record adapter devices, such as the large scale and complexity of the mechanism, and the high precision of the parts. 10 pages.
