Abstract

The utility model relates to a coaxial cassette tape. A box body is composed of a left box cover, a right box cover and an intermediate baffle plate seat. The axial leads of two wheel discs are coaxially installed respectively in the two spaces formed by the left and the right box covers and the intermediate baffle plate seat, and supported and positioned by an inward bulge loop of the box cover and a baffle plate. Two directive wheels are respectively installed on the outside edging above the two wheel discs, and the axial leads of four reverse wheels are installed slantways, wherein, two middle reverse wheels are respectively installed on the upper position near the directive wheel of each wheel disc, the other two upper reverse wheels are installed above the middle reverse wheels, and the middle branching of the two upper reverse wheels is right towards the middle branching of the baffle plate. When the utility model keeps the magnetic tape transporting smoothly, the length of the box body is reduced. The utility model occupies smaller space, and is convenient in using and storing.

Description

The coaxial-type magnetic tape cassette

The utility model relates to cassette audio tape, and concrete is a kind of coaxial-type magnetic tape cassette.

Cassette tape is to use cultural goods the most widely, the wheel disc of two wound tapes of existing magnetic tape cassette is that parallel axes is put, by angle sheave tape is sent to second wheel disc from first wheel disc, tape in the middle of two angle sheaves is recorded or playback during by magnetic head, though the magnetic tape cassette of this structure transmits steadily, but its box body is longer, does not effectively utilize thickness space, and its volume takes up space bigger.

The purpose of this utility model provides a kind of coaxial-type magnetic tape cassette, and two thickness aspects are not effectively utilized the space, and the wheel disc axial line axis of abide bing the contract is installed, keeping magnetic tape transport simultaneously stably, reduce the length of box body, minimizing takes up space, easy to use and preservation.

The purpose of this utility model is achieved in that

A kind of coaxial-type magnetic tape cassette comprises box body, wheel disc, and deflecting roller is wound with tape on the wheel disc, the corresponding record of tape, puts machine magnetic head place and is lined with cushion, and there is the convex moving tooth in wheel disk center, it is characterized in that:

Box body is made up of left and right lid and central dividing plate seat, and its dividing plate connects the cassette holder of four sides, and four jiaos of left and right lids become being connected of removable portion with screw and cassette holder;

Two wheel discs, axial line are contained in respectively in two spaces that left and right lid and central baffle seat formed coaxially, are positioned to be rotatably assorted to the internal projecting ring supporting by lid and dividing plate;

Two angle sheaves are contained in the outer side edges edge of two wheel discs top respectively;

Four reverse wheels, axial line tilts to install, wherein reverse wheel is contained in the top of both sides angle sheave respectively in the middle of two, put on two other reverse wheel be contained in the middle of reverse wheel the top and wherein separated time align separated time in the dividing plate, this last wheel face of putting reverse wheel on two is horizontally disposed with and makes tape flatly by above the cushion that aligns magnetic head;

Described each reverse wheel axis tilt suitably makes level and smooth rotation of tape be sent to second wheel disc that staggers in the position from first wheel disc.

Described four reverse wheels also can be conical wheels, and its last wheel face of putting the circular cone reverse wheel on two is horizontally disposed with and makes tape flatly by aligning the cushion top of magnetic head

Described each conical wheel tapering suitably makes level and smooth rotation of tape be sent to second wheel disc that staggers in the position from first wheel disc.

The utility model has following actively useful effect:

The coaxial-type magnetic tape cassette compared with the prior art, it is about 40% that its length reduces, its thickness increases few, thereby cumulative volume reduces, it is less to take up space, easy to use, stores and transportation.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is a structural representation of the present utility model, is front elevation;
