Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video deck, and more particularly, to a video deck having a cassette storage portion for storing a cassette and a cylinder disposed adjacent to and behind the cassette storage portion.

[0002]

2. Description of the Related Art Generally, a video deck is a real climbing 25764.
As in the technique disclosed in Japanese Patent Application Publication No. 80-80, a circuit on which a predetermined circuit is printed and various electric components are mounted is disposed inside a chassis. In addition, the video deck usually has a chassis in which a cassette storage portion for storing a cassette and a cylinder holding portion for holding a cylinder are formed. The cylinder is for recording and reproducing signals on and from the tape of the cassette, and is disposed adjacent to the rear of the cassette housing section.

[0003] Such a video deck tends to be manufactured in a smaller size in order to reduce the manufacturing cost. For example, since the space where the cassette storage section and the cylinder holding section are arranged requires the most space in the front-rear direction, the front-rear dimension (depth) of the VCR is automatically determined when the front-rear dimension of the deck on which these are formed is determined. Decided. On the other hand, the minimum lateral dimension of the VCR (width)
Because the deck is located above the center of the board,
Tall components such as power transformers, tuners, input / output jacks, etc. are located at the lateral edges of the board, thereby constraining the lateral dimensions of the board. Since such an arrangement is considered to be the most ideal in reducing the size of the video deck, it is difficult to further reduce the size.

In order to further reduce the manufacturing cost, it is conceivable to reduce the size of the substrate. The substrate is usually obtained by cutting a fixed-size substrate having a length of 1000 mm and a width of 1000 mm. Therefore, it is possible to cut costs by cutting as many substrates as possible from this substrate. For example, from this fixed size board,
Five substrates of 200 mm in length (front-back direction) can be taken, and six substrates of 166 mm in length can be taken. For this reason, even if the vertical dimension of the substrate can be made smaller than 200 mm, if it is longer than 166 mm, only the same number as in the conventional case can be obtained, so that cost reduction cannot be achieved. That is, in the case of a substrate having a length of 200 mm, it is necessary to reduce the length of the substrate to 166 mm or less in order to reduce costs.

However, it is necessary to mount components such as an input jack, a key switch, and a display device to be disposed at the front end of the chassis at the front end of the board, so that the position of the front end of the board is moved backward. I can't let that happen. On the other hand, it is necessary to mount components such as input / output jacks and tuner terminals to be placed at the rear end of the chassis at the rear end of the board, so move the position of the rear end of the board forward. Can not.

[0006] As described above, it is difficult to reduce the size of the board in a situation where the layout of the electric components mounted on the board is substantially determined.

[0007]

Incidentally, the video deck further includes a power cord extending outward from a lower portion of a rear end portion of the chassis. This power cord is packed
Usually, it is folded and placed behind the rear end of the chassis. For this reason, the carton for packing the VCR needs to be formed to secure a space for the power cord to be placed between the carton and the rear end of the chassis. Become.

[0008] However, in such a carton, the number of cartons that can be loaded in a predetermined space is reduced, so that the transportation cost is increased. Further, in such a configuration, the power cord is unstable between the VCR and the carton, so that the power cord may move around in the carton due to external vibration, impact, or the like during transportation. As a result, defects such as scratches on the product surface occur.

Here, a part of the rear end of the chassis is cut out to form a space in which the power cord can be arranged, thereby eliminating the need for a space between the VCR and the carton and reducing the size of the carton. It is possible to do.
However, such a method is not easy because a substrate is disposed below the rear end of the chassis and miniaturization of the substrate is difficult as described above.

An object of the present invention is to reduce the transportation cost while reducing the production cost of a video deck. Another object of the present invention is to provide a video deck in which the substrate is miniaturized due to cost reduction and which has improved strength.

[0011]

According to a first aspect of the present invention, there is provided a video deck, comprising: a cassette accommodating portion accommodating a cassette; and a cylinder disposed adjacent to and behind the cassette accommodating portion. A housing section, a deck section, a board,
It has a component part and a power cord.

[0012] The deck portion is arranged in the housing portion, has a cassette accommodating portion and a cylinder holding portion for holding the cylinder, and extends to a position adjacent to an inner wall facing the front and rear direction of the housing portion. The board is disposed below the deck in the housing, extends to a position adjacent to the inner wall at the front end of the housing, and has a length in the front-rear direction of 166 mm or less. The component part is mounted on the rear end of the board and arranged at the rear end of the housing. The power cord extends from a rear end of the housing.

[0013] The deck section is disposed in the housing section so as to secure a space above the component section. The part of the housing where the component part is arranged is located forward of the part where the deck at the rear end of the housing is adjacent.

Further, a lower portion of a rear end portion of the housing portion adjacent to the deck portion is chamfered. The chamfered portion of the housing has a plurality of supports having a boss extending upward from the inner wall of the chamfered portion to the deck, and a pin extending upward from the boss through the deck. The parts are formed side by side.

In the conventional video deck, since the rear end of the substrate is disposed below the rear end of the deck, a space for arranging the power cord is formed at the rear end of the housing. It was difficult.

However, in the video deck of the present invention, a part of the rear end of the housing (a part where components such as a tuner and an input / output jack are arranged) is replaced with another part (a part where the rear end of the deck is adjacent). ), A substrate having a shorter vertical length can be used. As a result, the position of the rear portion of the substrate, which was located below the rear end portion of the deck portion, has moved forward, and the lower portion of the rear end portion of the housing portion can be chamfered.

In this video deck, the lower portion of the rear end of the casing is chamfered, so that a predetermined space is formed below the chamfered portion and the carton. When the power cord is arranged in this space, there is no need to provide a gap for arranging the power cord between the rear end of the casing and the carton as in the conventional case, and the size in the carton front-rear direction is reduced. can do. As a result, the number of cartons that can be arranged in a predetermined space (for example, a shipping container) can be increased, and as a result, shipping costs can be reduced.

Therefore, here, it is possible to reduce the transportation cost while reducing the size of the substrate and the manufacturing cost. In addition, in this video deck, the rear end of the board moves forward due to the miniaturization of the board,
The rear end of the deck is separated from the housing.
However, the rear end of the deck portion is supported by the plurality of support portions, and as a result, the strength of the video deck is improved.

According to a second aspect of the present invention, there is provided a video deck including a cassette housing section for housing a cassette, and a cylinder disposed adjacent to and behind the cassette housing section. Unit, a substrate, a component unit, and a power cord. The deck portion is arranged in the housing portion, has a cassette housing portion and a cylinder holding portion for holding the cylinder, and extends to a position adjacent to an inner wall facing the front and rear direction of the housing portion. The substrate is disposed below the deck in the housing. The component part is mounted on the rear end of the board and arranged at the rear end of the housing. The power cord extends from the rear end of the housing. Further, the deck portion is disposed in the housing portion so as to secure a space above the component portion, and the portion where the component portion of the housing portion is disposed is a portion where the deck portion at the rear end of the housing portion is adjacent. It is located more forward. The lower portion of the rear end portion of the housing portion adjacent to the deck portion is chamfered.

In this video deck, the part in which the parts of the housing are arranged is located forward of the part adjacent to the deck at the rear end of the housing, so that the parts are mounted. The position of the rear end of the substrate has moved forward as compared with the conventional case. For this reason, in this video deck, a substrate smaller than the conventional one can be used. As a result, the rear end of the substrate, which was located below the rear end of the deck portion, is now located forward as compared with the conventional case, so that the lower portion of the rear end of the deck portion can be chamfered.

In this video deck, a predetermined space is formed below the chamfered portion, so that a power cord extending from the rear end of the housing can be arranged in this space. As a result, there is no need to provide a space between the carton and the rear end of the housing, unlike the conventional case,
Carton size can be reduced. As a result,
The number of cartons that can be loaded in a given space can be increased, thereby reducing transportation costs.

According to a third aspect of the present invention, the length of the board in the front-rear direction is 166 mm or less. In a conventional video deck, a substrate having a vertical length of about 200 mm is mainly used as a substrate.

However, in the video deck of the present invention, the position of the rear end of the substrate is located more forward than in the prior art,
For example, it has become possible to use a substrate having a vertical length of 166 mm or less. And if it is a substrate of this size,
You can take a larger number of substrates from a fixed size than before,
The cost of the substrate can be reduced.

Accordingly, the transportation cost can be reduced while the manufacturing cost of the video deck is reduced. A video deck according to a fourth aspect is the video deck according to the second or third aspect, wherein the substrate has a front end disposed in the housing portion adjacent to an inner wall of the front end portion of the housing portion.

As described above, since components such as a cassette insertion hole, a key switch, and a display device are arranged at the front end of the video deck, the front ends of the deck and the substrate are both at the front end of the housing. It extends to a position adjacent to the inner wall. Therefore, conventionally, it has been difficult to move the position of the front end of the substrate backward.

However, in the video deck of the present invention, since the position of the rear end of the substrate can be positioned forward, the size of the substrate can be reduced without moving the position of the front end of the substrate backward. became.

[0027] Therefore, in this case, in particular, the case where the front end of the substrate is located near the inner wall of the housing portion, and in such a video deck, the production cost is suppressed while the transportation cost is suppressed.

According to a fifth aspect of the present invention, in the video deck of any of the second to fourth aspects, the chamfered portion of the housing portion extends upward from the inner wall of the chamfered portion to the deck portion. A plurality of support portions each having a boss portion and a pin portion extending upward from the boss portion through the deck portion are formed side by side.

In this video deck, the size of the substrate is reduced, so that the rear end of the substrate moves forward, and the rear end of the deck is separated from the housing. However, the rear end of the deck portion is supported by the plurality of support portions, and as a result, the strength of the video deck is improved.

The second rear portion 17 is a portion formed on both sides of the first rear portion 15 in the lateral direction (left-right direction in FIG. 1), and is located forward (downward in FIG. 1) of the first rear portion 15, respectively. Is formed. Each of the second rear portions 17
It is formed to be separated from the front portion 13 by a length slightly larger than the vertical (front-back) length of the substrate 31.

The side portion 19 is a side portion between the front portion 13 and the second rear portion 17, and has two side portions 19.
Are formed at an appropriate distance from each other with respect to the lateral (lateral) length of the substrate 31.

The deck 21 is a metal member disposed in the chassis 11, and has a cassette storage section 23 and a cylinder holding section 25 formed therein. Cassette storage unit 23
Is a portion where the cassette inserted from the cassette insertion hole is stored. The cylinder holding section 25 is a section for holding a cylinder 26 that records and reproduces signals on and from a tape, and is formed adjacent to the rear of the cassette housing section 23.

In this embodiment, the length of the deck 21 in the front-rear direction is slightly smaller than the sum of the vertical length of the cassette stored in the cassette storage portion 23, the diameter of the cylinder, and the front-rear length of the tape path portion. It is getting bigger. This allows
Both ends in the front-rear direction of the deck 21 are arranged in the chassis 11 so as to extend to positions adjacent to the inner walls of the front portion 13 and the first rear portion 15.

At the rear end of the deck 21, a through hole 21a through which the pin 15d of the support 15b
Are formed side by side in a plurality. The substrate 31 is an insulating member made of a resin disposed below the deck 21 in the chassis 11. The substrate used in this embodiment has a length of 1
It has a size of 166 mm in length and 300 mm in width (side direction) cut out from a fixed-size substrate of 000 mm and 1000 mm in width. As a result, when the substrate 31 is disposed in the chassis 11, it extends to a position adjacent to the inner wall facing the chassis 11 in the lateral direction and to a position adjacent to the inner wall of the front portion 13 of the chassis 11.

The electric component 41 is a plurality of components mounted on the board 31, and includes a tuner 43, a plurality of input / output jacks 45, and a power transformer 47.
