## CPC

- G11B 23/08735: {Covers}
- G11B: INFORMATION STORAGE BASED ON RELATIVE MOVEMENT BETWEEN RECORD CARRIER AND TRANSDUCER (recording measured values in a way that does not require playback through a transducer G01D9/00; recording or playback apparatus using mechanically marked tape, e.g. punched paper tape, or using unit records, e.g. punched or magnetically marked cards G06K; transferring data from one type of record carrier to another G06K1/18; circuits for coupling output of reproducer to radio receiver H04B1/20; gramophone pick-ups or like acoustic electromechanical transducers or circuits therefor H04R)

## Abstract

There is provided a cassette case for containing a magnetic tape therein, including (a) a pair of cassette halves, the cassette halves being formed with a front opening through which a magnetic tape is to be exposed, (b) a pair of reels disposed in the cassette halves for rotation, (c) a magnetic tape wound around the reels, and (d) a guard panel including a front panel and a pair of side panels integral with the front panel at opposite ends thereof. The side panels is carried at the cassette halves so that the guard panel can rotate relative to the cassette halves and thereby the front panel opens and closes the opening. The front panel is formed with thicker-walled portions at each of which a groove is formed for locking the guard panel to the cassette halves. The front panel is formed with recesses closer to a proximal end of the front panel than the grooves, the recesses extending in a widthwise direction of the front panel.

## Claims

### Claim 1

A cassette case for containing a magnetic tape therein, comprising:
a pair of cassette halves, said cassette halves being formed with a front opening through which a magnetic tape is to be exposed;
a pair of reels disposed n said cassette halves for rotation;
a magnetic tape wound around said reels; and
a guard panel including a front panel and a pair of side panels integral with said front panel at opposite ends thereof, said side panels being carried at said cassette halves so that said guard panel can rotate relative to said cassette halves and thereby said front panel opens and closes said opening, said front panel being formed with thicker-walled portions at each of which a groove is formed for locking said guard panel to said cassette halves, said front panel being formed with recesses closer to a proximal end of said front panel than said grooves, said recesses extending in a widthwise direction of said front panel.

### Claim 2 (depends on 1)

The cassette case as set forth in claim 1, wherein said widthwise direction is the same as a direction in which said guard panel is pulled out of a die after said guard panel has been molded.

### Claim 3 (depends on 2)

The cassette case as set forth in claim 2, wherein said thicker-walled portions are formed by two.

### Claim 4 (depends on 3)

The cassette case as set forth in claim 3, wherein said thicker-walled portions are disposed at longitudinal ends of said front panel.

### Claim 5 (depends on 4)

The cassette case as set forth in claim 4, wherein said thicker-walled portions are symmetrically disposed.

### Claim 6 (depends on 1)

The cassette case as set forth in claim 1, wherein said thicker-walled portions are formed by two.

### Claim 7 (depends on 6)

The cassette case as set forth in claim 6, wherein said thicker-walled portions are disposed at longitudinal ends of said front panel.

### Claim 8 (depends on 7)

The cassette case as set forth in claims 7, wherein said thicker-walled portions are symmetrically disposed.
