JPS59151302A - Adaptor for ep record disk - Google Patents

Abstract

PURPOSE:To maintain the 2nd and succeeding EP record disk from the lowest position to be balanced by providing a keeper which has a slant face guiding center holes of the EP record disk and is provided to a side face opposite to a fixed receiving part of a housing while being energized so as to be projected always from the housing. CONSTITUTION:The keeper 4' is designed that a center hold ridge part 14 of the 2nd record disk 12b from the lowest position is caught by a tip part 15 of the keeper 4' without fail when the record disk 12b is positioned as shown in a figure and the center hole ridge part 14 of the record disk is not released from the tip part 15 of the keeper until the record disk 12b goes to the position state of a record disk 12a, that is, until the record disk 12b is shifted left by a dimension D. The relation of dimensions is set as A dimension > max. E and B dimension <min. E, where max. E is the maximum dimension of the center holes of EP record disks and min. E is the minimum dimension of center holes of said EP records. Thus, the effect for maintaining balancing is provided to the slant face of the keeper 4' when the 2nd record disk is positioned as the state of the record disk 12b.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a record changer for use with HP records, which has a structure in which a plurality of HP record discs are mounted and the records are automatically dropped and fed one by one onto a turntable. It concerns an adapter device.

Configuration of a conventional example and its problems A conventional adapter device is shown in FIG. In FIG. 1, 1 is a housing that can be divided into two parts, and is inserted into the center hole of an EP record. Reference numeral 2 denotes a fixed receiving portion for receiving a record, and is provided on a part of the side surface of the housing 1. The push plate 3 moves in response to the force υ caused by the movement of the upper end 11 of the record feeder 6, moves the lowest record 121L among the stacked records 12 in the direction of the arrow mark, and presses the turntable (not shown). z) drop it upwards.

The record feeder 6 moves in the direction of arrow B around a fulcrum 10 provided on the spindle 7, and serves to transmit the horizontal driving force received at the lower end 9 from the upper end 11 to the push plate 3. . ...Gipper 4, which is constantly urged to the left by Nee 8, picks up two of the dropped records during loading

12c side slip prevention city. The record presser 5 and the record receiver 5' are external balance maintaining devices for maintaining the balance of the record.

111 of the conventional HP record adapter device;
The type of device that horizontally moves and drops the record discs, such as the one shown in Fig. 1, has only one fixed receiving part 2 on the housing. There is a drawback that an external balance maintaining device is required, such as one set in which the upper part is held down by an arm, or a system in which the peripheral part of the outermost row of the record is supported by -1 as in the record holder 5'. In particular, with regard to maintaining the balance between the two records 1 and 1 from the bottom A☆ record, which is a problem in comparison with the present invention, the keeper 4 plays a role in preventing lateral slippage +4'i-. The parts that make up the other adapter devices only perform the same role as Keeper 4.
However, the only way to maintain equilibrium was to rely on an external balance maintainer. For this reason, the mechanism is dependent on the mechanism, and the mounting angle of the record holder 5, the mounting of the record holder 6' and the adapter device described above must be assembled while paying close attention to the positions, etc., resulting in various difficulties in manufacturing. was there.

However, there are other types of conventional adapters that do not require an external balancing device as described above, but instead maintain the balance of the record within the adapter itself.

The adapter device is equipped with two or more receivers that receive the area around the center hole of the record from below and a feeder that drops the records one by one, but all of these receivers are movable receivers. At the same time, the receiver is housed in the housing and the lowest record is dropped.
For the second or more record discs, the plurality of receivers may be protruded from the housing at the same time to receive the lower surface, or the center hole of the second or more record discs should be moved toward the outer periphery. Structure that holds by pressing and 5 pages
Since the mechanism is complex and high dimensional accuracy is required for each part, the adapter drive direction of the record changer is also complicated, as the drive direction of the adapter device is in the 10-to direction. There are some notable drawbacks.

OBJECTS OF THE INVENTION The present invention obviates these conventional drawbacks,
To provide an adapter device for EP records that can maintain the balance of two or more EP records on the lowest beam with a simple configuration that does not use an external balance maintenance device.

Structure of the invention The non-inventive feature is that by appropriately setting the = value of the key bar 2 fixed receiver, the two EP records from the bottom of the stack can be
As long as the first record moves in parallel in the C direction along the inclination direction of the giver, the lowest record will fall down from the adapter device. This is an adapter device for EP records that can hold records stably and in equilibrium.

Explanation of Example 6 Par:! FIG. 2 shows an embodiment of the present invention. Also in Figure 2,
As in the conventional case, the stacked records 12 are lowered by their own weight along the slope of the keeper 4' which is always biased toward the protruding side, but the second record 12b from the bottom is shown in FIG. The center hole edge 14 of the record is set so that it always catches the tip 15 of the keeper 4' when the record is in the state, and furthermore, the record 12b is set so that it catches the tip 15 of the keeper 4'. When the record center hole edge 1 reaches the state of
4 is set to be released from the keeper tip 16. In other words, the dimensional relationship of each part is determined as follows. E
If the innermost dimension of the center hole diameter of a P record is maxE, and the smallest diameter of the same center hole is winE, then the relationship is set as follows: A dimension'>maxE8 dimension<m, 1-nE. In this way, when the second record is in the state 12b, the keeper 4' In addition to the conventional record disc slippage prevention function, the slope of the 7-page slope can also have an effect of maintaining balance.

In this embodiment, the movable receiving part 1 is located below the keeper 4'.
7 is provided, and the movable receiving portion 17 together with the fixed receiving portion 2 receives the area around the center hole of the lowest record 12a. When a driving force is applied to the record feeder (6 in FIG. 1), this movable receiving portion 17 moves into the housing 1 in conjunction with the push plate 3 shown in FIG. Effect of the invention for dropping the record 121L According to the present invention, compared to the conventional IP record adapter device, there is no need for an external balance maintaining device to keep the second or more records in equilibrium. , all those parts can be discontinued. Moreover, since there is no need for multiple moving parts that move in and out of the housing at the same time, the structure of the adapter itself becomes extremely simple. Furthermore, since the driving direction is horizontal rather than vertical, the mechanism of the record changer itself can be simplified, resulting in many advantages such as miniaturization and improved operability.
