제 3 도는 본 고안 레코드 플레이어의 외관 사시도.3 is an external perspective view of the record player of the present invention.
본 고안은 픽업의 위치에 따라 레코드판의 음구(音溝)와 무음대(無音帶)를 구별하여 검출하고, 이것을 표시하도록 한 레코드 플레이어에 관한 것이다.The present invention relates to a record player which distinguishes and detects the sound sphere and the silent band of a record board according to the position of a pickup.
음악등이 여러곡 녹음되어 있는 LP 레코드판의 도중의 곡부터 연주를 개시하는 경우, 종래는 픽업을 그곡의 서두(序頭)의 무음대 상방에 짐작으로 갖다올려 놓아 곡의 시작을 행하여 왔기 때문에, 시작이 불확실해지고, 또 레코드판을 상할 염려도 있고, 또 시작된 때에는 상당한 주의력을 요하는 것이었다.In the case of starting performance from the middle of the LP record version where music is recorded several times, conventionally, since the pickup has been picked up above the silent band of the song, the beginning of the song has been performed. The beginning was uncertain, there was a risk of breaking the record, and when it was started it required considerable attention.
본 고안은 상기와 같은 문제를 해결하기 위한 것으로, 레코드판의 음구와 무음대의 빛의 반사율이 다른 것을 이용하여, 픽업의 카아트리지에 발광소자와 수광소자(受光素子)를 취부하여, 빛의 반사량이 다른 것에 의해 음구와 무음대를 구별하는 검출신호를 취출하고, 이 검출신호에 의해 픽업이 음구상방에 있는가 무음대 상방에 있는 가를 픽업 셀의 설치한 표시용 발광소자에 의해 표시하도록 한 것이다.The present invention is to solve the above problems, by using the light reflectance of the record plate and the silent band is different, attaching the light emitting element and the light receiving element to the cartridge of the pickup, the amount of light reflection According to this difference, a detection signal for distinguishing between the sound sphere and the silent zone is taken out, and the detection signal is used to indicate whether the pickup is above the sound sphere or above the silent zone by the display light emitting element provided in the pickup cell. .
이하 본 고안의 실시예를 도면에 의해 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the drawings.
제 1 도는 본 고안의 원리를 나타낸 것으로, (1)은 픽업 카아트리지이고 하면에 램프, 발광 다이오드등의 발광소자(2)와 포토트랜지스터 등의 수광소자(3)이 취부되어 있다. (4)는 레코드판으로, 음구(5)와 무음대(6)를 가지고 있다. (7)은 후술하는 표시용 발광소자이다.1 shows the principle of the present invention, (1) is a pickup cartridge, and a light emitting element 2 such as a lamp and a light emitting diode and a light receiving element 3 such as a phototransistor are mounted on the bottom surface thereof. (4) is a record board, and has a musical instrument (5) and a silent band (6). (7) is a display light emitting element described later.
동도에서, 발광소자(2)의 빛은 무음대(6)에서는 정반사되어 반사광 L1으로 되어 수광소자(3)에 도달하나, 음구(5)에서는 산란하기 때문에 그 일부의 반사광 L2만이 수광소자(3)에 도달한다. 이때 L1의 광량은 L2의 2~3배로 된다. 따라서 수광소자(3)은 반사광 L1에 대하여서만 동작할 수 있는 것이다.In the same figure, the light of the light emitting element 2 is specularly reflected at the silent band 6 to become the reflected light L 1 and reaches the light receiving element 3, but since the light sphere 5 scatters, only part of the reflected light L 2 is received. To reach (3). At this time, the light amount of L 1 is 2-3 times of L 2. Therefore, the light receiving element 3 can operate only with respect to the reflected light L 1 .
제 2 도는 상기 제 1 도의 원리를 이용하여 검출신호를 얻기 위한 회로로서, (2')는 램프, (3')는 포토트랜지스터, (7')는 표시용 발광 다이오드, T1,T2는 차동증폭기를 구성하는 트랜지스터, T3는 스위칭트랜지스터, R1,R2…R8은 저항, C는 콘덴서, (8)(8')는 전원단자이다. 램프(2')를 발광시키고, 픽업을 아암리스트에서 집어올려, 수동 또는 공지의 이동수단으로, 레코드판(4) 상방에 이동시키면, 램프(2')로부터의 빛은 레코드판(4)에서 반사되나, 전술한 바와같이 음구(5)와 무음대(6)의 반사량이 다르기 때문에, 도면의 경우는 카아트리지(1)이 무음대(6)의 상방에 온때, 이 무음대(6)에서의 반사광 L1에 의해 포토트랜지스터(3')가 온으로 된다. 이 때문에 트랜지스터 T1이 온으로 되고 트랜지스터 T3을 온으로 한다. 따라서 트랜지스터 T3의 콜렉터에 전류가 흘러 발광다이오드(7')가 발광한다. 카아트리지(1)이 음구 상방에 온때는 포토트랜지스터(3'), 트랜지스터 T1,T3는 각각 오프로 되어 발광다이오드(7)의 발광이 꺼진다. 따라서 픽업의 이동에 따라, 카아트리지(1)이 음구(5) 및 무음대(6)의 상방을 통과할때 발광 다이오드(7')가 점멸(點滅)하게되어, 발광하고 있는 때에 픽업을 레코드판(4)상에 하강시키면 희망의 곡의 시작을 확실히 행할 수 있다. 또 저항 R6을 변경하여 트랜지스터 T2를 개재하여 트랜지스터 T1의 에미터의 레벨을 변경시켜, 레코드판(4)의 종류(예로서 적색의 것)에 따라 반사광 레벨이 다르게 반응동작시킬 수 있다.2 is a circuit for obtaining a detection signal using the principle of FIG. 1, wherein 2 'is a lamp, 3' is a phototransistor, 7 'is a display light emitting diode, and T 1 , T 2 are A transistor constituting the differential amplifier, T 3 is a switching transistor, R 1 , R 2 . R 8 is a resistor, C is a capacitor, and (8) and (8 ') are power supply terminals. When the lamp 2 'is made to emit light, the pick-up is picked up from the arm list, and moved by the manual or known moving means above the record plate 4, the light from the lamp 2' is transferred to the record plate 4; Although the reflection amount of the sound sphere 5 and the silent band 6 is different as described above, in the case of the drawing, when the caratridge 1 comes above the silent band 6, of the reflected light is in the photo transistor (3 ') by L 1-one. Because of this, the transistor T 1 is turned on and the transistor T 3 is turned on. Therefore, a current flows through the collector of the transistor T 3 and the light emitting diode 7 'emits light. When the cartridge 1 comes above the sound sphere, the phototransistor 3 'and the transistors T 1 and T 3 are turned off, respectively, so that light emission of the light emitting diode 7 is turned off. As the pickup moves, therefore, the light emitting diode 7 'flashes when the cartridgeage 1 passes above the sound sphere 5 and the silent zone 6, and the pickup is performed when light is emitted. When descending on the record board 4, the start of the desired song can be surely performed. In addition, the level of the emitter of the transistor T 1 is changed through the transistor T 2 by changing the resistor R 6 , and the reflected light level can be reacted differently depending on the type of the record plate 4 (for example, red color). .
제 3 도는 발광다이오드(7')를 설치한 레코드 플레이어의 실시예를 나타낸 외관 사시도로서, (10)은 플레이어본체, (11)은 뚜껑, (12)는 픽업아암, (13)은 아암 리프터, (14)는 속도변환스위치, (15)는 픽업복귀를 위한 자동, 수동절환스위치, (16)는 턴테이블이다. (17)은 픽업셀로서, 본 고안에서는 이 픽업셀(17)에 상기 표시용 발광소자(7)를 취부하고 있는 것으로, 도면에서는 픽업셀(17)의 상면에 취부하고 있다. 또 본도에서는 발광소자(2) 및 수광소자(3) 등을 포함하는 반사광 검출부(18)도 이 픽업셀(17)에 취부되어 있으나, 상기 픽업아암(12)등에 취부하는 것도 가능하다. 또, 전술한 검출 신호를 얻는 회로는 제 2 도의 것에 한하지 않고 몇몇의 회로로 변경하는 것도 가능한 것은 물론이며, 또 본 고안은 비데오 디스크에도 적용할 수 있는 것이다.3 is an external perspective view showing an embodiment of a record player provided with a light emitting diode 7 ', where 10 is a player body, 11 is a lid, 12 is a pickup arm, 13 is an arm lifter; 14 is a speed change switch, 15 is an automatic and manual switching switch for pickup return, and 16 is a turntable. Reference numeral 17 denotes a pickup cell. In the present invention, the display light emitting element 7 is attached to the pickup cell 17. In the drawing, the display cell 7 is mounted on the upper surface of the pickup cell 17. As shown in FIG. In addition, although the reflected light detection part 18 including the light emitting element 2, the light receiving element 3, etc. is attached to this pick-up cell 17 in this figure, it is also possible to attach it to the pick-up arm 12 etc. The circuit for obtaining the above-described detection signal is not limited to that of FIG. 2, but can be changed to several circuits. The present invention can also be applied to a video disk.
본 고안에 의하면, 픽업의 카아트리지에 발광소자와 수광소자를 취부하여, 레코드판의 음구 등의 신호구와 무음체 등의 무신호대에서의 상기 발광소자로부터의 빛의 반사량이 다른 것을 상기 수광소자로 검출하고, 이 검출신호에 의해 표시용 발광소자를 발광시켜, 상기 카아트리지가 상기 음구 상방에 있는가 상기 무음대 상방에 있는가를 표시하도록한 레코드 플레이어에 있어서, 상기 표시용 발광소자를 플레이어 픽업셀에 설치하여, 레코드판의 시작을 할 경우, 픽업을 간단히 레코드판 상방에 이동시키는 것만으로, 픽업 셀에 설치된 발광소자의 점멸을 보면 카아트리지의 위치를 확실히 판정할 수 있기 때문에, 시동조작을 간단히 또 안전하게 행할 수 있고, 또 발광소자는 점멸하면서 픽업셀과 함께 이동되기 때문에 극히 그 조작이 용이하다는 등의 효과를 얻을 수 있는 것이다.According to the present invention, the light-emitting element and the light-receiving element are attached to the cartridge of the pickup, and the light-receiving element is different in the amount of reflection of the light from the light-emitting element at a signal sphere such as a sounding plate of a record plate and a non-signaling zone. A record player which detects and emits a light emitting element for display according to the detection signal so as to indicate whether the cartridge is above the sound sphere or above the silent zone, wherein the display light emitting element is provided in a player pickup cell. When the recorder starts, simply picking up the pickup above the recorder plate makes it possible to reliably determine the position of the cartridge when the flashing of the light emitting element installed in the pick-up cell makes it possible to start the operation easily and safely. And the light emitting element is moved together with the pick-up cell while blinking, making it extremely easy to operate. The effect of which would be obtained.
