Title: Pickup device for optical information signal reproducer
Inventor: TAJIMA OSAMU
IPC: G11B7/12
Filed: 1984-05-21
Abstract: PURPOSE:To reproduce the information without reducing the quantity of the reflected luminous flux by dividing the reflected light sent from a recording medium into two parts in the extending direction of the record track orthogonal to the optical axis and providing a cylindrical lens having its action axis tilted by 45 deg. to the light dividing surface together with six photodetecting elements to receive the divided beams. CONSTITUTION:The beams sent from a light source 1 are condensed on the signal surface of a recording medium 7 in the form of a light spot 6 having a minute diameter and then reflected. The inverted circular polarized light is reflected on a reflecting surface 3a of a polarizing prism 3. The reflected light is transmitted through a condenser lens 8, a cross wedge type prism 9 and a cylindrical lens 10 and then divided into two parts by a straight line parallel in the extending direction of the record track of the medium 7 orthogonal to the optical axis. These two divided beams are also tilted by about 45 deg. to each dividing surface and received by a photodetecting part PAD containing photodetecting elements PD1-PD6 arranged as desired to said divided beams. The outputs of elements PD1-PD6 are calculated. Thus it is possible to obtain the focus error signal, the tracking error signal, the reproduction information signal, etc. with no loss of the light quantity at all to the total reflected luminous flux.

Accordingly, in spite of a shortage of engine output due to a drop in atmospheric pressure, the required driving force comes to be secured. With this constitution, favorable accelerability comes to be securable even at time of highland travel.

An output of the heater 5, therefore, becomes high as convectional radiation of the radiation fin 8 is done together with radiation and convectional radiation of the heater 5. The heat pipe 6 does not become fuctional normally and the convectional radiation of the radiation fin 8 either reduces or becomes zero by making the heat pipe 6 horizontal or into a handstand state. The radiation and convectional radiation, therefore, become main and the output is reduced. The output can be switched to either low or high.
