Provided is a tuner device including: a box-shaped metal tuner case; a plurality of connectors which are attached to one surface of the tuner case; a plurality of connection pins for signal transmission, the pins being provided on the other surface of the tuner case; and at least one foot electrode which is provided in the vicinity of the connection pins and is grounded.

Tuner device

Disclosed is a tuner device including an input terminal, a separator, a first amplifier, a second amplifier, and a tuner. The input terminal receives an input of a reception signal of satellite digital broadcasts. The separator is connected to the input terminal and adapted to frequency-separate a first signal and a second signal. The first signal is in a low-frequency domain of the reception signal, and the second signal is in a high-frequency domain of the reception signal. The first and second amplifiers respectively amplify the first and second signals. The tuner receives an input of output signals from the first and second amplifiers.

A coaxial connector includes a cylindrical external conductor including a metal material, a first insulating member arranged in the external conductor, a second insulating member including a front surface plate in which a wire insertion hole is formed and a plurality of elastic pieces which extends from the front surface plate toward a rear surface and of which an end overlaps with a side of a front surface of the first insulating member and is movable in a direction from a front surface toward a rear surface, and a center electrode arranged in a hollow portion in the first and second insulating members and including a terminal led out from a rear surface of the first insulating member to outside and clamping pieces for clamping the wire connected to the terminal.

Coaxial connector, high frequency unit, and receiver

An information recording medium cartridge is provided with a disc, a cartridge casing having the disc accommodated therein, first and second shutters movably mounted to the cartridge casing for opening and closing recording and/or reproducing openings arranged in right and reverse sides thereof. First and second slide members having the first and second shutters are mounted on the shutters. First and second shutter plates are provided with a shutter main body that overlaps the right side or the reverse side of the cartridge casing to open and close the opening and a slide-member mounting portion for mounting the first and second slide portions to the shutter main body at an end. The slide-member mounting portion is provided with an engaging claw, wherein when mounting the first and second slide portions, the engaging claw is engaged with a claw engagement provided to the slide portion.

Information recording medium cartridge

An information recording medium cartridge with a disc, a cartridge casing having the disc accommodated therein, and a shutter slidably mounted to the cartridge casing. The shutter has a first shutter plate for opening and closing a recording and/or reproducing opening of the cartridge casing and a second shutter plate for opening and closing the recording and/or reproducing opening on another side. The first and second shutter plates are independently movable between first and second positions for closing and opening the recording and/or reproducing openings.
