Abstract

PURPOSE:To miniaturize the titled selector by providing an extracting device which shifts a recording medium to a reproducing device and this reproducing device in one body with a shift device and shifting these devices up to the storing part of the recording medium. CONSTITUTION:When a cassette case 1e is selected by an operator, a motor 13 is driven to move up a lifter 2. In this case, a controller calculates the position of the case 1e and stops the drive of the motor 13. Then a revolution command is outputted to a motor 41 from the controller to start the revolution of a composite cam 39. Then a drive plate 51 moves left to put holder bars 22 and 25 into a housing 1. At the same time, a bell crank 42 is revolved counterclockwise to pull an action cord 46. Thus an upper member 19 is revolved and the case 1e is held between bars 22 and 25. Then the plate 51 is moved right and a loading arm 49 is turned to lead a cassette case extracting device 3 into the lifter 2. Then a lift arm 57 moves up in response to a cam 39c, and a tape mechanism 4 is pulled out and loaded to the case 1e to operate reproduction.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention stores a plurality of recording media, each of which is an independent entity, such as a cassette tape or a compact disc, in advance, and stores the required number of recording media from the storage section according to an operator's instruction. This invention relates to an automatic recording medium selection device that takes out a recording medium, automatically puts it into a playback device, and then returns the recording medium to an optical storage position after the playback is finished.

[Background of the invention]

It! s-Media automatic selection technology has been widely used in jukebox record selection, computer data processing systems, etc., but in recent years, the large capacity of the recording media storage section in this type of device has increased. As the technology advances, there is a demand for faster operation, smaller size, and greater efficiency.

A conventional automatic selection device of this kind has a structure in which a playback device is fixed and a recording medium ejecting device is reciprocated between the playback device and a recording medium storage section to convey a desired recording medium to the playback device. Because of this, it takes a long time to transport the recording medium to the playback device, and this disadvantage becomes especially noticeable when taking out a recording medium stored far away from the playback device, making it impossible to meet the recent demands for speeding up. “There is a drawback.

In addition, this type of device generally has complicated operations, but in conventional devices, the power transmission mechanism itself to perform this complicated operation is complicated and expensive, and it is said that it cannot meet the recent demands for miniaturization and efficiency. There are drawbacks.

[Purpose of the invention]

The present invention solves the drawbacks of the above-mentioned conventional automatic selection devices of this type, and provides an automatic recording medium selection device that is small in size, can accommodate a large amount of recording media, can quickly reproduce recorded contents, and can be manufactured at low cost. This is what we are trying to provide.

Next, the operation of the automatic cassette tape selection device according to the present invention constructed as above will be explained.

First, before the operator issues a command, the cassette case ejecting device 3 has not been retracted into the H lowering body 2, and the tape mechanism 4 has been released from the force press 1. When the operator operates an indicating device (not shown) to select the -cassette 1-case, for example 1e, the motor 13 rotates and the elevating body 2 moves upward. At this time, a control device (not shown) calculates the count number of the sensor 14 and the position before the accompaniment starts, determines the positions of the sword set 1 to case 1'e, and when the elevating body 2 reaches the required position, the motor is activated. Stop and wet. Subsequently, the control device issues a rotation command to the motor 41, and the composite cam 39 starts rotating via the required power transmission mechanism 40. When the composite cam 39 starts rotating, the drive plate 51 first moves to the upper left in FIG. The pieces 22 and 25 are pushed into the storage body 1. At the same time as this state is reached, the cassette case ejecting device 3
The opening/closing cam 39a engages the small diameter portion, and the bell crank 42 rotates to the left in FIG. 2 about the fulcrum 43.
The operating water 46 of the release 45 is pulled.

When the operation s46 of the release 45 is pulled, the upper member J9 of the cassette case ejecting device 3 moves to the second position about the fulcrum 17.
It rotates to the left in the figure and clamps the cassette case 1e between the clamping piece 25 of the upper member 19 and the clamping piece 22 of the lower member 18.

Subsequently, the drive plate 51 moves to the right in FIG. 1 according to the cam 3'9b, and the four loading arms rotate to the right around the fulcrum to take out the cassette case connected to the loading arms! [3 is drawn into the elevating body 2. In this case, the spring 56 stretched between the anchor 29 of the cassette case ejector @3 and the elevating body 2 acts to press the anchor 29 to the left when it is on the left, and vice versa. When the anchor 29 is on the right side, it acts to suppress it, so the cassette case ejecting device 3 is always fixed at a fixed position currently held at both ends of the elongated hole 31 formed in the elevating body 2. Be able to do it. Subsequently, the lifting arm 57 of the tape mechanism is raised by the cam 39C, and the tape mechanism 4 is attached to the cassette 1-case 1e pulled out as described above to perform a playback operation. As the cuff rotates, each part of the device returns to its original position through a process that is the reverse of the above process.

In the above embodiment, a system in which the recording media are stacked vertically has been described, but the gist of the present invention is not limited to this, and can be implemented in exactly the same way even when the recording media are arranged side by side on the left and right.

In addition, in the above embodiment, only the case where a cassette tape is used as the recording body is explained7, but the gist of the present invention is not limited to fins. Of course, the present invention can also be applied to other recording media in exactly the same way.

〔Effect of the invention〕

The recording medium automatic selection device according to the present invention takes out the recording medium from the storage section and fixes the reproducing device to the reproducing device. How do I transfer the recording medium to storage money 5?
With this structure, compared to the conventional playback device fixed method, the time required to transport the removed recording medium to the playback device can be omitted, and the speed of the ghost processing can be sped up. The present invention is particularly excellent in that the effect becomes more pronounced as the number of recording media to be stored increases. Further, as a result of integrating the recording medium automatic selection device number retrieval device and the playback device according to the present invention, these drive mechanisms can be integrated, and the device can be made into a /JX type. In particular, since the drive shaft number: a large number of cams of a predetermined shape are set together at a predetermined timing, the structure of this part is significantly miniaturized, and together with the effect of the front part, the device can be miniaturized. b11 It is possible to improve the storage capacity of self-recording media.

Furthermore, since the driving shaft is integrated using a composite cam, the number of motors can be kept to a minimum, and an efficient and inexpensive device can be manufactured.
