Description
【０００１】[0001]
本考案はチューナ、ＩＦアンプ及びＲＦコンバータを一つのシャーシ容器に収 容し、しかもＮＴＳＣ方式とＰＡＬ方式に共通形状のシャーシにすることのでき るチューナ、ＩＦアンプ及びＲＦコンバータ回路一体型ＶＴＲ装置に関する。 The present invention relates to a VTR device integrated with a tuner, an IF amplifier and an RF converter circuit, which is capable of accommodating the tuner, the IF amplifier and the RF converter in a single chassis container, and further forming a chassis having a common shape for the NTSC system and the PAL system. .
【０００２】[0002]
従来のＶＴＲ装置のチューナ、ＩＦアンプ及びＲＦコンバータ回路を一個のシ ャーシ容器に収容した一体型構造を図３〜５に示す。 図３は扁平な長方体状の前記シャーシ容器の正面図，図４は図３のＸ−Ｘ線断 面図，図５は側面図である。 FIGS. 3 to 5 show an integrated structure in which a tuner, an IF amplifier and an RF converter circuit of a conventional VTR device are housed in one chassis container. 3 is a front view of the flat rectangular parallelepiped chassis container, FIG. 4 is a sectional view taken along line XX of FIG. 3, and FIG. 5 is a side view.
【０００３】 図中で１はシャーシ容器の板，１ａはシャーシ容器の側面板，２はＰＣＢ基板 ，３はＰＣＢ基板に実装されている前記回路の電子部品，４はアンテナ入力と出 力の２個のＦ接栓，５は前記回路からの信号端子群である。 図３〜５に示されるように２個Ｆ接栓４は長方体状シャーシ容器の最も面積の 少ない側面板１ａに取付けられている。 このようなＦ接栓横出しタイプの構造により、コンパクトな一体型構造のシャ ーシ容器が可能となっていた。In the figure, 1 is a plate of a chassis container, 1a is a side plate of the chassis container, 2 is a PCB substrate, 3 is an electronic component of the circuit mounted on the PCB substrate, 4 is an antenna input and 2 outputs. Each F plug, 5 is a group of signal terminals from the circuit. As shown in FIGS. 3 to 5, the two F plugs 4 are attached to the side surface plate 1a having the smallest area of the rectangular chassis container. With such a structure of the F-connector horizontal projection type, it has become possible to provide a compact chassis container having an integrated structure.
【０００４】[0004]
しかしながら、ＰＡＬ方式ではアンテナ入力と出力の２個のＦ接栓も含めて、 ＲＦコンバータ出力周波数可変のバリコンやトリマーに接続する軸回転ネジと、 Ｉ／Ｋ，Ｇ／Ｋ方式切換スイッチ、および同調テスト信号発生器のＯＮ／ＯＦＦ 切換スイッチの取り付けが必要となる。 従来のＦ接栓横出しタイプのシールド容器では図 の側面図１ａの残りスペー スに前記スイッチやネジ類を取付けることはできない。取付けられるように側面 板を広げれば、シールド容器の容積は必要以上に増加し、コンパクト化に逆行す る。 However, in the PAL system, including the two F plugs of the antenna input and output, the shaft rotation screw connected to the variable converter and trimmer of the RF converter output frequency variable, I / K, G / K system changeover switch, and tuning It is necessary to install the ON / OFF switch of the test signal generator. In the conventional F-plug side-opening type shield container, the switches and screws cannot be attached to the remaining space in the side view 1a in the figure. If you expand the side plate so that it can be attached, the volume of the shield container will increase more than necessary, and it will go against compactness.
【０００５】 またＮＴＳＣ方式でもＲＦコンバータ出力周波数のチャンネル切換スイッチを 取付けコンパクトにしたいが、Ｆ接栓横出しタイプの一体型構造では取付けられ ない。In addition, even in the NTSC system, it is desired to mount a channel changeover switch for the RF converter output frequency to make it compact, but it cannot be mounted in the integrated structure of the F-connector sideways type.
【０００６】 本考案の目的は上述した事情に鑑みてなされたもので、上記Ｆ接栓横出しタイ プのシールド容器の欠点をなくし、しかもＰＡＬ方式とＮＴＳＣ方式に共通形状 のシールド容器にしてコストダウンを計ることを目的としたチューナ、ＩＦアン プ及びＲＦコンバータ回路一体型ＶＴＲ装置を得ることを目的とする。The object of the present invention was made in view of the above-mentioned circumstances, and eliminates the drawbacks of the above-mentioned shield container of the F-connector sideways type, and further, makes the shield container of a common shape for the PAL system and the NTSC system costly. An object of the present invention is to obtain a VTR device integrated with a tuner, an IF amplifier and an RF converter circuit for the purpose of measuring down.
【０００７】[0007]
上記課題を解決するための手段として、本考案は、テレビ電波のチューナと、 その映像信号のＩＦアンプと、ビデオ信号をテレビ信号に変換するＲＦコンバー タ各回路を収容した一個の長方体状の電磁遮蔽シャーシ容器を具備し、前記シャ ーシ容器は高さ及び横巾に比較して奥行きの短い扁平な形状であり、そのシャー シ容器の広い前面は、アンテナ入力及び出力のＦ接栓と、信号の切換やＯＮ／Ｏ ＦＦに使うスイッチと、バリコンに接続する軸回転ネジが取付けられ、シャーシ 容器の底面は前記回路からの信号端子群が取付けられていることを特徴とする。 As a means for solving the above problems, the present invention is directed to a rectangular parallelepiped housing that accommodates a tuner for TV radio waves, an IF amplifier for the video signals, and RF converter circuits for converting video signals to TV signals. The chassis container has a flat shape with a shorter depth than the height and width, and the wide front surface of the chassis container has an F input plug for antenna input and output. And a switch used for signal switching and ON / OFF, and a shaft rotating screw connected to the variable capacitor, and a group of signal terminals from the circuit is mounted on the bottom surface of the chassis container.
【０００８】[0008]
チューナとＩＦアンプ及びＲＦコンバータの各回路電子部品を実装したＰＣＢ 基板を１個の扁平長方体シャーシ容器内に収容し、その最も広い前面にはアンテ ナ入力と出力のＦ接栓を取付けてＦ接栓前出しタイプにする。この２個のＦ接栓 からそれぞれテレビ電波の入力とＲＦコンバータからテレビ信号の出力を行う。 The PCB board on which each circuit electronic component of the tuner, IF amplifier, and RF converter is mounted is housed in one flat rectangular chassis container, and the F input plug of the antenna input and output is attached to the widest front surface. F plug type is the first type. Television signals are input from these two F plugs and television signals are output from the RF converter.
【０００９】 上記のようなＦ接栓前出しタイプにしたので、以下に示すようにシャーシ容器 の奥行を増加することなくスイッチやネジ類を同一前面に取付けできる。 すなわち、ＰＡＬ方式の場合には、Ｆ接栓と同一前面に次のように作動する軸 回転ネジとスイッチ類を取付ける。それらはＲＦコンバータ出力周波数可変用の バリコンやトリマーに接続する軸回転ネジと、Ｉ／Ｋ，Ｇ／Ｋ方式切換スイッチ と同調テスト信号発生器のＯＮ／ＯＦＦスイッチである。Since the F plug front advance type is used as described above, the switches and screws can be mounted on the same front surface without increasing the depth of the chassis container as shown below. That is, in the case of the PAL system, the shaft rotating screw and switches that operate as follows are installed on the same front surface as the F plug. They are a shaft rotation screw connected to a variable condenser or trimmer for changing the output frequency of the RF converter, an I / K, G / K system changeover switch, and an ON / OFF switch of the tuning test signal generator.
【００１０】 一方ＮＴＳＣ方式の場合には、Ｆ接栓と同一前方に切換スイッチを取付け、Ｒ Ｆコンバータ出力周波数のチャンネル切換を行えるようになる。On the other hand, in the case of the NTSC system, a changeover switch can be attached to the same front side as the F plug to switch the channel of the RF converter output frequency.
【００１１】 Ｆ接栓前出しタイプとしたため、ＰＡＬ方式、ＮＴＳＣ方式いづれの場合も、 両方式に使用できる同一寸法構造のシャーシ容器でよく、また、スイッチやネジ 類の取付けのため一体型構造のシャーシ容器の奥行寸法は増加させなくて良い。Since the F plug front type is used, a chassis container of the same size structure that can be used for both the PAL system and the NTSC system can be used for both systems, and an integrated structure for mounting switches and screws. The depth dimension of the chassis container need not be increased.
【００１２】[0012]
図１，２はそれぞれＰＡＬ方式の場合の本考案の一実施例を示す。 図１はＦ接栓前出しタイプのシャーシ容器の正面図、図２はＹ−Ｙ線断面図を 示す。 図中１１は電磁遮蔽シャーシ容器の板、１１ｂはシャーシ容器前面の板、１２ はＰＣＢ基板、１３は回路の電子部品、１４はアンテナ入力、出力のＦ接栓，１ ５は回路からの信号端子群である。 １６はバリコントリマーの軸回転ネジ，１７はＩ／Ｋ，Ｇ／Ｋ方式の切換スイ ッチ，１８は同調用テスト信号発生器ＯＮ／ＯＦＦ切換スイッチである。 1 and 2 show an embodiment of the present invention in the case of the PAL system. FIG. 1 is a front view of a chassis container of the F plug insertion type, and FIG. 2 is a sectional view taken along line YY. In the figure, 11 is a plate of an electromagnetic shielding chassis container, 11b is a plate on the front face of the chassis container, 12 is a PCB substrate, 13 is electronic parts of a circuit, 14 is an antenna input / output F plug, and 15 is a signal terminal from the circuit. It is a group. 16 is a rotary screw of a variable condenser trimmer, 17 is an I / K, G / K type changeover switch, and 18 is a tuning test signal generator ON / OFF changeover switch.
【００１３】 以上のようにＦ接栓前出しタイプは、従来のＦ接栓横出しタイプの構造寸法を 大きくすることなしにスイッチ，ネジ類をＦ接栓と同一面に取付けられる。As described above, the F-plug front extension type allows the switches and screws to be mounted on the same surface as the F-plug, without increasing the structural dimensions of the conventional F-plug horizontal extension type.
【００１４】 上記シャーシ容器１１は、ＮＴＳＣ方式のシャーシ容器にも使用することがで きる。その場合は例えば図１の方式切換スイッチ１７をＲＦコンバータ周波数チ ャンネル切換スイッチとして配線すればよい。 すなわち、シャーシ容器１１はＰＡＬ方式とＮＴＳＣ方式共通の構造で製造し ておくことができる。The chassis container 11 can also be used as an NTSC system chassis container. In that case, for example, the method changeover switch 17 of FIG. 1 may be wired as an RF converter frequency channel changeover switch. That is, the chassis container 11 can be manufactured with a structure common to the PAL system and the NTSC system.
【００１５】[0015]
以上延べた本考案のようにＦ接栓前出しタイプとすることにより、チューナ、 ＩＦアンプ及びＲＦコンバータ回路を収容したシャーシ容器の奥行を増やすこと なく、コンパクトのままスイッチやネジ類を同一面に取付けることができる。 By adopting the F plug front extension type as in the present invention as described above, the switches and screws can be kept on the same surface without increasing the depth of the chassis container housing the tuner, IF amplifier and RF converter circuit. Can be installed.
【００１６】 また、ＰＡＬ方式とＮＴＳＣ方式とに共通な同一寸法構造のシャーシ容器とす ることが可能となり、機構部品の共通化，設備や治具等の共通化によるコストダ ウンと、一体型構造の設計標準化が計れて総合的コストダウンとなる。Further, it becomes possible to make a chassis container of the same size structure common to the PAL system and the NTSC system, and the cost down due to the common use of the mechanical parts, the equipment and the jig, and the integrated structure. Design standardization can be achieved, resulting in total cost reduction.
