置に摺動変位し、これでハブ３を自由回転状態にする。There, when not in use, the front lid 13 is closed to cover the outside of the tape 2 led out to the front of the main case 1.
When the hub lock member 21 is in the rear lock position, the hub 3
To prevent rotation. When the tape cartridge is loaded onto the deck, the front cover 13 rotates upward around the pivot 15, and in conjunction with this, the hub lock member 21 slides forward to the unlocked position, which causes the hub 3 to rotate freely. Make it.
前蓋１３とハブロック部材２１との連係手段としては１
本体ケース１の左右横側壁の前端部にハブロック部材２
１から延びる連係部３ｏを導出し。The means for connecting the front cover 13 and the hub lock member 21 is 1.
A hub lock member 2 is attached to the front end of the left and right side walls of the main body case 1.
A connecting portion 3o extending from 1 is derived.
前蓋１３の左右の連結片１４が該連係部３０に接当係合
してハブロック部材２１を前方に引き寄せる形態を採っ
ている。The left and right connecting pieces 14 of the front lid 13 abut and engage with the connecting portion 30 to draw the hub lock member 21 forward.
前蓋９とハブロック部材２１との連係手段に注目すると
、従来では第６図に示すごとく下ケース１ｂの横側壁の
外面に摺動光は面３２を形成し。Focusing on the linking means between the front cover 9 and the hub lock member 21, conventionally the sliding light forms a surface 32 on the outer surface of the lateral wall of the lower case 1b as shown in FIG.
この摺動光は面３２にハブロック部材２１から前方に長

っていた。This sliding light receives on the surface 32 a linking portion 30 that extends long forward from the hub lock member 21. In this way, the sliding light is directed toward the surface 32 when the connecting portion 30 is bent and deformed toward the center of the case.
, and the connecting piece 14 of the front cover 13 is connected to the connecting part 3.
It was designed to abut and engage with a passive protrusion 31 provided at the front end of 0.
しかるに、この種のテープカートリッジの組付けに際し

ングねしなどで結合する仕様を採ることがあるが、この
場合に従来形態では問題があった。However, when assembling this type of tape cartridge, the front cover 13 and the hub lock member 21 are assembled in the upper case 1a in advance, and the hub 3 and the hub lock member 21 on which the tape 2 is wound are assembled in advance.
In some cases, a specification is adopted in which the above-mentioned ``2'' case 1a is placed over the lower case lb in which necessary parts such as 3 are assembled, and the upper and lower cases 1a and 1b are connected using tapping screws. There was a problem.
すなわち、下ケース１ｂに」二ケース１ａを被せ付ける
際に、先組みした前蓋１３を上開き回動した状態にして
おく必要がある。それは前蓋１３が下ケース１ｂにつか

合爪２５がハブ３の上端に乗り掛がって組付は不良状態
になるからである。That is, when placing the second case 1a on the lower case 1b, it is necessary to keep the previously assembled front cover 13 in an upwardly rotated state. This is partly to prevent the front cover 13 from getting stuck in the lower case 1b, but most importantly, the hub lock member 21 must be slid forward to the unlocked position. For example, as shown in FIG. 9, the hub lock member 21 is provided with an engaging pawl 25,
5 abuts and engages with the outer circumferential portion of the upper end of the hub 3 from the front, and when the hub lock member 21 is in the rear lock position, the engaging pawl 25 rests on the upper end of the hub 3, preventing assembly. This is because it will be in a bad state.
ところが、前出の従来例では摺動光は面３２が下ケース

結片１４と連係部３０が確実に係合せず、ハブロック部
材２１がロック解除位置に摺動変位しないまま組付けら
れて作動不能状態を招きがちであった。However, in the conventional example mentioned above, the surface 32 of the sliding light is formed on the center side of the lower case, and is not on the side of the upper case la. Therefore, as shown in FIG. 7, the front end of the linking part 30 of the hub lock member 21 is deformed toward the center of the case, and the linking piece 14 of the front lid 13 and the linking part 30 do not engage reliably, and the hub lock member 21 This tends to result in an inoperable state if the device is assembled without being slid into the unlocked position.

ことである。Here, although it is said that the front cover 13 is pre-assembled to the upper case 1a, it does not mean that the pivot 15 of the front cover 13 is completely pivoted to the upper case la side, but also includes a temporarily attached state. For example, as shown in the conventional example in FIG.
- The pivot 15 may be completely pivotally connected to the shaft hole formed between the lid mating surfaces of the two lids only after the two lids are connected. This concept can be similarly applied to the hub lock member 21.

る。According to the present invention as described above, the hub lock member 21
Even if the linking part 30 extends forward for a long time, the sliding light on the center side of the upper case is received by the surface 32 of the linking part 30, and is prevented from deforming toward the center of the case and escaping. Therefore, after assembling the front cover 13 and the hub lock member 21 on the upper case 1a, the upper and lower cases 1a and 1b are assembled together.
When the front lid 13 is rotated upward to connect the lids together, a part of the front lid 13 (the connecting piece 14 in the illustrated example) connects with the linking part 3.
0, the hub lock member 21 can be moved to the forward unlocked position. the result,
The lids of the upper and lower cases 1a and 1b can be joined together smoothly, and in particular, the hub lock member 21 is not assembled in a malfunctioning state, and one assembly can be expected to dramatically improve work efficiency.
