Abstract

PURPOSE:To regulate surely a forward progress limit of a shutter by providing a stopper restricting the forward progress of the shutter in abutting on a part of the shutter to left/right side walls of a lower case. CONSTITUTION:The shutter 18 opening/closing a pocket 10 for tape loading is fitted slidably along the bottom wall 4 and the left/right side walls of the lower case 1b and energized to the forward of case by a spring member 25. A stopper 53 capable of abutting on a lock piece 40 of the shutter 18 is formed to the left/right side wall of the lower case 1b. Thus, even when the shutter 18 is energized forward by the spring member 25, the shutter 18 abuts on the stopper 53 and the forward progress limit is regulated surely. Thus, the amount of left/right progress of the shutter 18 has no difference and approaches to the front cover 12 with a correct gap.

に突き当たり謄平になることは前Ｍ１２の閉じ姿勢の維
持その他から好ましくない。In this type of tape cartridge, one problem of the present invention is how to limit the forward movement limit of the shutter 18. That is, when this type of shutter 18 is not in use, dust may enter from the bottom surface of the opening of the pocket 10 and cause the tape 2 to leak.
The main objective is to prevent the polish from adhering to the surface, and the front end of the gloss 18 should be opposed to the lower end of the inner surface of the front i12 as closely as possible when not in use. However, the shutter 18 that is biased to slide forward
It is undesirable for the front M12 to run into a closed position and become flattened.

しておき。However, as a conventional technique for regulating the limit of forward movement of the shutter 18, the use of a locking means for the shutter 18 was attempted in the previous Japanese Patent Application No. 110274/1983. As shown in FIG.
(A lock piece 38 that selectively engages with the cough lock holes 36 and 37 is integrally formed on the Ill so as to be elastically deformable in the vertical direction.

イヤ側の部材で上方に押して摺動ロンゲを解除する。When the shutter 18 is in the forward sliding position that closes the lower surface of the pocket 10, the lock piece 38 engages in the lock hole 37 on the rear side with its own elastic force and locks the sliding movement of the shutter 18. Even when the pocket 10 is in the rear sliding position where the lower surface of the pocket 10 is opened, the four pieces 38 engage the front lock holes 37 to lock the sliding movement of the gloss 18. The lock pieces 38 that are engaged in the respective lock holes 36 and 37 are pushed upward by a member on the player's side to release the sliding longue.

Since it is necessary to fit and engage smoothly with 7, it is unavoidable that some looseness will occur during the fitting, and it is unreasonable to strictly define the front 1 movement field of the no. In other words, a gap must be provided with considerable flexibility between the front teeth of the gloss 18 and the lower end of the inner surface of the front lid 12, and this gap tends to become large. In addition, the four hook means are biased toward one side, the left and the right, due to the opening shape of the pocket 10, etc. It is set on two sides. In the illustrated example, it is located off to the left.

い。On the other hand, in the state in which the upper and lower cases 1a and 1b constituting the main body case 1 are stacked, the upper case 1a (III or the mating surfaces of the upper and lower cases la and 1.b)
A form that restricts the forward advance limit number contact of 8 was also considered. However, with this, the front sliding position of the gloss 18 will be out of order due to poor stacking or poor assembly (positional deviation) of the upper and lower cases 131b, and the lower case 1b' will be incorrectly installed/The relationship between the Yanota 18 and the upper case 1a Sushi is an area that is influenced by this. In addition, it is not possible to assemble the 7-piece 1B into the lower case 1b first, and the upper case 1a must be attached to the lower case 1b in relation to the shutter 18, which results in poor workability for one assembly.
