- G11B 15/67555: {the second movement only being made by the cassette holder}
- 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

A new tape player capable of playing a normal magnetic tape and a chrome tape. A selector lever is pivotally provided in the chassis. The lever has, at its one end, a bent probe portion. This bent probe portion is urged to come into engagement with a chrome tape indicating aperture to ensure that an electric circuit for a chrome tape is turned on.

## Claims

### Claim 1

A cassette tape player comprising:
a chassis;
a head base adapted to take a retracted position and an advanced position relative to a loaded cassette;
probe means for detecting a chrome tape indicating aperture formed in said loaded cassette, said probe means being normally urged into engagement with said aperture;
control means coupling said head base and said probe means for holding said probe means out of engagement with said aperture while said head base takes the retracted position; and
switch means for turning on an electric circuit for a chrome tape by the probe means being urged into engagement with the chrome tape indicating aperture.

### Claim 2 (depends on 1)

A cassette tape player according to claim 1, wherein said probe means includes a selector lever pivotally provided within the chassis and having at its one end a bent probe portion; and a tension spring provided between the chassis and the lever to urge the bent probe portion into said engagement with the aperture.

### Claim 3 (depends on 1)

A cassette tape player according to claim 1, wherein said head base is moved by an actuating plate between the retracted position and the advanced position.

### Claim 4 (depends on 3)

A cassette tape player according to claim 3, wherein said control means includes an interlocking bar normally urged toward and abutted against said actuating plate at its one end and having a bent portion at its other end to engage the selector lever.
