Abstract

PURPOSE:To improve the rigidity of a half case and also to improve the reliability by providing ribs for reinforcement near opening parts and at outer circumferences of reels on the internal surface of the half case. CONSTITUTION:The ribs 14a and 14b for reinforcement are stood integrally near tape lead-out parts 13a and 13b at both sides of the opening part 2 on the internal surface of the half case 1 and at the outer circumferences of the reels. Consequently, the rigidity of the half case is improved to prevent the half case from deforming during use, thereby improving the convenience of use and the reliability greatly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to raw recording devices such as video tape recorders.
The present invention relates to tape cassettes that are most suitable for application to <() and other various information processing devices.

Conventional Structures and Problems Generally, tape cassettes of this type have structures as shown in FIGS. 1 and 2. In the figure, 1 is a half case, 2 is an opening provided on the front surface of this bar hook 71, and 3 is a magnetic tape with a running path formed so as to be exposed to the outside in this opening 1. The reels 4 and 5 are rotatably supported and housed in the half cane 1 described in OII.
A front cover is provided to open and close the self-opening part 2 of the ii-work iM'+, and the shafts 7 at both ends of this front cover 60 are rotatably supported by the front iM+ part of the half case 1. There is.

Reference numeral 8 denotes a rear lid rotatably supported by a bearing portion 9 provided on the inner surface of the front cover 6;
1 opens and closes in conjunction with the opening and closing of the lid 6, and the magnetic tape 3 exposed at the opening 2 is sandwiched between the front bath 6 and sealed.

1o is nIJ record! Brake part A, A, 11 is a locking member for locking the front cover 6 in the closed state, and 12 is an erroneous erasure prevention part. 3 In the tape cassette described above, a standing wall is formed on the outer periphery of the half case 1, but the opening of the bar case 71 is
Tape drawer portions 13a on both sides of part 1 20.

13b does not have a vertical wall, so its rigidity is weak, and deformation during use causes problems in terms of usability and reliability.

OBJECTS OF THE INVENTION The present invention aims to solve these conventional drawbacks and to provide a chive cassette with a structure that does not undergo deformation during use.

Structure of the Invention In order to achieve this object, the present invention provides a half case in which a reel wound with a magnetic tape is rotatably supported and housed and has an opening in the front surface through which the magnetic tape is exposed; The half case is provided with a lid provided to open and close the opening at the front of the half case, and a reinforcing lip is provided near the opening on the outer periphery of the IJ on the inner surface of the half case. . According to this configuration, the rigidity of the half case can be improved and deformation during use can be eliminated.

DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to FIG. 3, with the same numbers assigned to the same parts as described above.

As shown in FIG. 3, in the present invention, the inner surface of the half case 1 is marked with 1'4iJ in the vicinity of the tape pull-out parts 13a and 13b on both sides of the opening 2. A reinforcing lip 14a is provided on the outer periphery of the
14b is installed vertically at -(((().

Effects of the Invention As described above, in the present invention, by providing a reinforcing lip near the opening on the outer periphery of the reel on the inner surface of the half case, the rigidity of the half case can be improved. No deformation occurs, and usability and reliability can be significantly improved.
