The present invention relates to a tape recognition device for analog and digital compact cassettes, and more particularly, a lever springably installed on a deck to be rotatably installed, and the lever is installed to be in contact with a tape recognition switch of a circuit board. The analog and digital compact cassettes allow for the selective recognition of analog and digital compact cassette tapes without affecting the overall thickness and space of the deck mechanism, as well as the ease and ease of application to automotive cassette decks. A tape recognition device.

Generally, cassette tapes are classified into analog compact cassettes and digital compact cassettes. The digital compact cassette tapes have a digital compact cassette tape 10 at one corner as shown in FIG. Sensing hole 12 for determining whether or not) is formed, and a square hole 14 is formed on the other side, the analog compact cassette tape 16 is as shown in (b) of FIG. The projections 18 are formed on both sides of the analog compact cassette 16.

In the tape recognition apparatus of the conventional analog and digital compact cassette as described above, as shown in FIG. 2, the tape recognition switch 22 is used for sensing the cassette tape at the seating position of the cassette tapes 10 and 16 on the deck. By being inserted into the hole 12 so that it can be inserted, the tape recognition switch 22 operates according to the presence or absence of the sensing hole 12 when the cassette tape is used, and the tape recognition switch 22 is operated. According to the on / off operation of the analog and digital compact cassette, respectively, the operation of the tape recognition switch 22 determines whether it is the analog compact cassette tape 16 or the digital compact cassette tape 10. It will be recognized.

However, in the tape recognition apparatus of the conventional analog and digital compact cassettes as described above, the thickness of the entire deck mechanism of the cassette deck itself is increased, and the tape recognition switch protrudes upward to recognize whether the digital or analog compact cassette is used. As a result, a large amount of space in the deck is required, whereas a cassette deck implemented in a vehicle has a narrow installation area, which makes it difficult to install the tape recognition switch.

The present invention is to solve the conventional problems as described above, an object of the present invention, the lever is installed on the cassette deck spring-loaded resiliently rotatable, the lever is in contact with the switch for the tape recognition of the circuit board The installation makes it easy to selectively recognize analog and digital compact cassette tapes without affecting the overall thickness and space of the deck mechanism, thus enabling analog and digital applications to be easily applied to cassette decks for vehicles. It is an object of the present invention to provide a tape recognition device for a compact cassette.

A feature of the present invention for achieving the above object is that the tray is installed so that the cassette tape is inserted into the cassette deck, the cassette tape to be seated on the tray at one end of the deck to recognize the switch for the tape recognition of the circuit board In the tape recognition device of the analog and digital compact cassettes installed, a lever is installed on one side of the deck to be resiliently installed through a spring to be rotatable, and the lever is installed so that one end is in contact with the tape recognition switch. By providing a tape recognition device.

Hereinafter, the tape recognition apparatus of the analog and digital compact cassette according to the present invention will be described in detail by the accompanying drawings of a preferred embodiment.

As shown in FIGS. 3A and 3B, a tray 24 into which the cassette tapes 10 and 16 are inserted and seated in the deck 20 is installed, and the tray 24 is a tape. The bracket 30 having the pressing plate 28 is elastically installed by the spring 32.

The tray 24 is installed on the deck 20 to move up and down, and a cassette tape 16 having a lever 26 elastically installed on the deck 20 as a spring 36 is inserted into the tray 24. It is installed to be in contact with the protruding portion 18 while being lowered, and the lever 26 rotates backward while the lever 26 is in contact with the protruding portion 18, and the tape recognition switch 22 mounted on the circuit board 34. It is configured to be in contact with the configuration.

The spring 36 may be any one as long as the lever 26 can be returned to its original position. A tension coil spring or a torsion spring is preferable.

Referring to the operation and effects of the present invention configured as described above are as follows.

As shown in FIG. 3, when the analog compact cassette tape 16 is inserted into the tray 24 on the deck 20 and lowered, the analog compact cassette tape 16 has a projection 26 formed on the side surface thereof. By rotating the end portion of the), one side of the tape recognition switch 22 of the circuit board 34 by pushing the tape recognition switch 22 in accordance with the rotation of the lever 26 (On) It can be recognized that the analog compact cassette tape 16.

On the contrary, when the digital compact cassette tape 10 is seated and lowered when the deck 20 is inserted into the tray 24 on the deck 20, the digital compact cassette tape 10 is lever 26 in the square hole 14 formed on the side. The tape recognition switch 22 of the circuit board 34 is turned off because one side of the lever 26 does not push the tape recognition switch 22 so as not to contact the end of By doing so it can be recognized that the digital compact cassette tape (10).

Therefore, the present invention rotatably installs the lever 26 elastically installed on the deck 20 via the spring 36 and the lever 26 is in contact with the tape recognition switch 22 of the circuit board 34. By being installed as such, it is possible to recognize analog and digital compact cassette tapes without affecting the overall thickness and space of the deck mechanism, thus making it easy to apply them to cassette decks for vehicles.

In addition, the deck 20 uses a lever 26 elastically installed by a spring 36 and a square hole 14 and a projection 18 of the cassette tape 10 and 16 to provide a tape recognition switch 22. In operation, the device for recognizing whether the digital compact cassette tape 10 or the analog compact cassette tape 16 is relatively simple and thus, the production is easy.

As described above, according to the tape recognition device of the analog and digital compact cassette according to the present invention, the lever is installed in the cassette deck spring-loaded resiliently rotatably, so that the lever is in contact with the tape recognition switch of the circuit board Due to the installation, it is possible to easily recognize analog and digital compact cassette tapes selectively without affecting the overall thickness and space of the deck mechanism, and thus there is an effect that can be easily applied to cassette decks for vehicles.
