Description

Structure of connecting main slider to main chassis of magnetic tape recorder}

The present invention relates to a tape recorder, and more particularly, to a coupling structure of a main chassis of a deck provided with a tape loading device and a main slide member of the tape loading device.

In general, a tape recorder having a deck mechanism, such as a video (VTR), a camcorder (CAMCORDER), a digital audio tape (DAT), or the like, uses a recording medium, that is, a magnetic tape, that is transferred along a predetermined driving path. It is a device for recording / reproducing video information. The recording / reproducing of such information is performed by the contact between the magnetic tape and the head drum.

1 and 2 illustrate the structure of a camcorder in the tape recorder 100 as an example. The tape recorder 100 includes a head drum 15, a tape driving unit for driving a magnetic tape, and a tape loading / unloading unit. And a tape loading device which contacts or spaces the tape in the head drum 15 in the loading mode.

As shown in the drawing, the tape loading apparatus includes a tape loading unit including a tension pole 31, a plurality of base poles 33, a pinch roller 34, and the like, and the tape loading unit in place during tape loading / unloading. And a loading driving part 40 including a loading motor 41, a loading gear 43, and a main slide member 20 to provide a driving force to move.

In the tape loading device configured as described above, the loading gear 43 is rotated when the loading motor 41 is driven during tape loading / unloading, and the main slide member 20 is loaded with the loading gear 43 in cooperation with the loading gear 43. The link member 37 having the projection 37a inserted into the guide hole 25 of the main slide member 20 is converted into a linear reciprocating motion by the movement of the main slide member 20. By reciprocating, the tape loading portion is placed in a predetermined position in each mode.

Here, the main slide member 20 is installed on the bottom surface of the main chassis 10 so as to be capable of linear reciprocating in one direction, and by having a cam protrusion 29 inserted into the cam hole 43a of the loading gear 43. As the loading gear 43 rotates, the main slide member 20 is linearly reciprocated.

In the conventional tape recorder 100, a separate coupling member 50 inserted into a plurality of slide holes 21 and 22 formed in the main slide member 20 should be coupled to the bottom surface of the main chassis 10.

The coupling member 50 is typically provided with a gap maintaining protrusion 50a for maintaining a gap between the main slide member 20 and the loading gear 43 and between the loading gear 43 and the main chassis 10. A stud boss or the like having a guide groove 50b is used, which is coupled to the main chassis 10 by a predetermined process during assembly. Accordingly, in assembling the product, the number of parts is increased by using the coupling member 50, and a predetermined assembly process for coupling the coupling member 50 to the main chassis 10 is added.

Accordingly, in the production of the product through an automated process, as a separate process is added, productivity is lowered, and a separate coupling member has to be installed, thereby increasing the production cost of the product by adding parts.

Disclosure of Invention The present invention has been made to solve the above-described problems, and an object thereof is to provide a tape recorder having an improved coupling structure between a main slide member and a main chassis in order to improve product productivity and reduce manufacturing cost.
