[Problems to be solved by the device]

FIG. 9 is a schematic partially enlarged sectional view shown for explaining the positional relationship between the opening 13 and the accommodating portion 15 in the conventional auto changer 10. Like FIG. 8, 11 is a case, Reference numeral 12 is an insertion / ejection portion, 13 is an opening portion, 14 is a magazine, 15 a _{1 to} 15 a ₃ are respective stages of the accommodating portion 15, and 14 c and 14 d are insertion / ejection ports. The height A of the DIN standard size case 11 is specified to be approximately 46 mm, while the space B in the steps 15a ₁ , 15a ₂ , ... Is required to be approximately 5 mm due to the MD thickness. The plate thickness C needs to be about 1 mm, and the minimum gap D between the magazine 14 and the case 11 needs to be about 1 mm. Further, below the magazine 14, the above-mentioned amplifier, tuner, or board mounting space is required.

Therefore, in order to satisfy the above constraint conditions, in the case of the autochanger 10 having the _three stages 15a _{1 to} 15a ₃ , the height E of the magazine 14 is approximately 19 mm, and the lower edge of the opening 13 and the lower part of the case 11 are equal to each other. The distance F is set to about 27 mm. When the MD 18 is inserted into and ejected from the opening 13 to the lowermost stage 15a ₃ , the magazine driving device 16 (FIG. 8) moves the magazine 14 to a predetermined position above the case 11, and the magazine 14 and the lower part of the case 11 at this time. And the distance G between them is about 26 mm. Further, as shown by the alternate long and short dash line, when the MD 18 is inserted into and ejected from the uppermost stage (15a ₁ ), the magazine 14 is moved to a predetermined position below the case 11, and the distance H at this time becomes approximately 14 mm, and therefore, A mounting space for a board or the like is secured.

Will be set to approximately 21 mm, respectively. When the MD 18 is inserted into and ejected from the opening 13 to the lowermost stage 15a ₄ , the distance G between the magazine and the lower part of the case 11 is about 20 mm. Further, when the MD 18 is inserted into and ejected from the uppermost stage 15a ₁ , the distance H becomes approximately 2 mm, and therefore, the mounting space for the substrate and the like is eliminated.

In the conventional auto changer 10 described above, four stages 15a are provided.₁ ~ 15a _Four However, if a magazine is formed, the mounting space H for boards, amplifiers, tuners, etc. cannot be secured, and therefore there are at most three stages 15a.₁ ~ 15a₃ However, there is a problem that only the magazine 14 in which the MD is formed can be arranged, and the storage amount of the MD 18 is insufficient. Further, in order to reduce the size of the autochanger 10, it is necessary to further reduce the storage amount of the MD 18, which makes it difficult to meet the demand for downsizing.

Further, since the driving rollers are arranged in the respective stages 15a ₁ , 15a ₂ , ... Of the accommodating portion 15, there is a problem that the cost is high and the opening 13 and the respective stages 15a ₁ , 15a ₂ , If the relative position with respect to the drive roller is not surely matched, there is a problem that it is difficult to insert the MD 18 to a predetermined position in the inner part of each of the steps 15a ₁ , 15a ₂ , ... due to the relationship with the drive roller.

The present invention has been made in view of the above problems, and it is possible to secure a mounting space for substrates and the like, and increase the number of stages of the accommodating portion to increase the MD storage amount, or The size of the MD can be reduced while maintaining the MD storage capacity, and the opening and the housing can be accurately positioned, so that the MD can be inserted and removed smoothly and reliably, and the cost can be reduced.
