Abstract

PURPOSE:To enable miniaturization and thin information without giving harmful influence upon its design by inclining a cabinet against a mechanism substrate, moving an upper dead space to the lower side of the substrate and disposing a required constitutive element in this space. CONSTITUTION:One part of a cassette lid 15 and a bottom cabinet 16 are inclined against the mechanism substrate 11 provided with a head and a pinch roller, etc., on its upper side, and the dead space between a cassette tape 12 and the lid 15 is moved to the lower side of the substrate 11. Then, when a print circuit board 18 mounted with a rectangular Ni-Cd battery 17 and a switch 19, etc., and so forth are disposed in the space on the lower side, an inside space is effectively used keeping the thicknesses H1 and H2 of both sides almost the same. As a result, the cassette tape recorder can be miniaturized and reduced in thickness without giving harmful influence upon its design.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a cassette tape recorder.

BACKGROUND OF THE INVENTION In recent years, cassette tape recorders have become significantly smaller and thinner.

Such miniaturization and thinning are greatly influenced by the shape and configuration of the external cabinet, the arrangement of internal parts, etc. Figure 3,
Fig. 4 shows a conventional general cassette tape recorder. In Figs. 3 and 4, 1 is a mechanism board for driving the cassette tape 2, 3 is on the upper surface side of the mechanism board, and the cassette tape is 2 is a top side cabinet serving as a cassette lid body for storing the mechanism board 1, a bottom side cabinet 4 is located on the bottom side of the mechanism board 1 and houses the mechanism board 1, and 6 is a magnetic head and a pinch roller provided on the mechanism board.

Problem to be Solved by the Invention However, in the cabinet shape and configuration of the conventional cassette tape recorder as described above, as is clear from FIG. 3, a space ▲ exists between the cassette tape 2 and the cassette lid body 3. , this space ▲ becomes wasted space for ultra-compact and thin design.

On the other hand, if the shape of the cassette lid body 3 is made to follow the shape of the cassette tape 2 in order to eliminate the space ▲ as shown in FIG. The shape is also determined by the surface. There was a problem that the product was not well organized.

Therefore, in view of these conventional problems, the present invention aims to provide a cassette tape recorder that can be made ultra-compact and thin, without wasting space, and with a high degree of freedom in design. be.

Means for Solving the Problems In order to achieve the above object, the cassette tape recorder of the present invention is capable of housing a mechanism board on one edge of which is provided with a head, pinch rollers, etc. The upper side cabinet is provided with a top side cabinet for storing a cassette tape of the mechanism board, and a bottom side cabinet of the mechanism board, with the side opposite thereto as a first side surface and the side opposite thereto as a second side surface. The second side surface is made relatively thinner than the side surface. The lower side cabinet is formed by forming the first side surface thinner than the second side surface.
The present invention is characterized in that the sum of the thickness dimensions of the cabinets on the upper surface side and the lower surface side of the mechanism board on the side surface and the second side surface is substantially the same.

Further, in the cassette tape recorder of the present invention, a prismatic battery for driving a mechanism that determines the thickness of the second side surface is provided in the lower cabinet of the mechanism board near the second side surface, and the second side surface of the lower cabinet The present invention is characterized in that the outer shape of the vicinity of the cassette tape approximately follows the shape of the rectangular battery, and the outer shape of the upper cabinet approximately follows the convex portion of the head opening of the cassette tape.

Effects The present invention has the following effects due to the above-described configuration.

According to the cassette tape recorder of the present invention, wasted space in the vicinity of the second side surface between the flat surface part other than the convex part where the cassette tape head and the pinch roller are inserted and the inside of the cabinet is eliminated, and the space in the vicinity of the second side surface on the lower surface side of the mechanism board is eliminated. This has the advantage that the space has been moved in the same way as in the previous example, and that the set thickness can be made thinner.

Further, according to the cassette tape recorder of the present invention, a prismatic battery is configured in a space near the second side surface on the lower surface side of the mechanism board, the lower cabinet runs along the prismatic battery, and the upper cabinet runs along the cassette tape. By not following the shape, there is no strange feeling in the external shape of the set.
It also contributes greatly to the design.

EXAMPLES Hereinafter, examples of the present invention will be described in detail based on the drawings.

FIG. 1 is a sectional view showing an outline of an embodiment of the cassette tape recorder of the present invention, and FIG. 2 is a perspective view showing the overall structure of FIG. 1. In FIG. 1, 11 is a flywheel 111 for driving the cassette tape 12.
It is a mechanism board with L etc. 13 is a magnetic head, and 14 is a head block having pinch rollers and the like. 16 is a cassette lid shaped like the cassette tag 12 and housing the cassette tape 12; 16 is shaped like a square nickel-cadmium battery (hereinafter referred to as a square battery) for driving the mechanism. This is a bottom cabinet that stores the lower surface side of the mechanism board 11. 18
is provided in parallel with the mechanism board 11, and the switch 19
This is a printed circuit board on which electrical components such as the following are mounted. The thickness H1 of the first side surface having the head block 13 and the thickness H2 of the second side surface opposing thereto are substantially the same.

With the above configuration, the space between the cassette tape 12 and the cassette lid 16, which was conventionally a dead space, is brought to the bottom side of the mechanism board 11, thereby saving space for the square battery 17 and mounting space for the printed circuit board. This results in effective use of space. Also, place the bottom cabinet 16 along the rectangular battery 17 and cover the cassette lid 1.
6 along the cassette tape 12, it does not have a negative impact on the design even when it is becoming smaller and thinner.
The effect is great.

Effects of the Invention The present invention is achieved by tilting the cabinet, which was conventionally parallel to the mechanism board. The space between the cassette tape and the cassette lid, which used to be a lot of dead space, has been moved to the bottom of the mechanism board, making it possible to effectively use it as space for a square battery or mounting space for a printed circuit board, making it smaller and thinner. , or greatly contributes to multifunctionalization. Further, according to the component configuration of the present invention, it is possible to provide an ultra-compact and thin set that does not look out of place in terms of design even if the cabinet shape conforms to the internal components.
