A TV conference system, which enables a conference to be conducted between remotely located points, includes a plurality of terminal equipment disposed in the remotely located points for enabling information, such as image information and sound information, to be communicated from one of the remotely located points to another in real time, a controlling circuit for enabling the terminal equipment disposed in one of the remotely located points to be controlled from another, and an operation restricting circuit for restricting execution of a predetermined operation of the terminal equipment which can be operated under remote control. Accordingly, there is provided a TV conference system including an improvement which can provide good operability to a conference participant. In addition, the operability of the system is improved to a further extent by improving an image input apparatus.

A recording and/or reproducing apparatus having a cassette loading device. The loading device includes a first holding member for holding a cassette and a second holding member which is located behind the first holding member relative to a cassette inserting direction and is arranged separately from the first holding member to hold the cassette in conjunction with the first holding member. The arrangement facilitates assembly and adjustment work on the loading device and particularly on cassette holding devices.

A video conference system includes a detecting circuit for detecting an amount corresponding to a movement delay, if the movement delay occurs in a terminal device prepared at a second point when the terminal device is made to perform the movement, in accordance with an instruction sent from the first point, and a memory circuit for storing the amount corresponding to the movement delay detected by the detecting circuit. The device is made to move in a direction opposite to the direction in which the device has been made to move, on the basis of the amount stored in the memory circuit.

Disclosed is a head shifting apparatus for shifting a head relative to a recording medium, which comprises a shifting mechanism for shifting the head stepwise, detecting means for detecting when the head reaches a predetermined reference position and control means for controlling the shifting mechanism in such a manner that the head is shifted in a first shifting mode where the head is shifted on the basis of a predetermined first unit increment of shifting step until the head reaches the reference position, and after that when to perform normal recording or reproducing, the head is shifted in a second shifting mode where the basis is shifted on the basis of a predetermined second unit increment of shifting step larger than the first unit increment of shifting step.
摘要:
A recording and/or reproducing apparatus using a record bearing medium contained in a cassette which is provided with at least one positioning hole formed therein. The apparatus is provided with an engaging member which is engageable with the positioning hole for loading the cassette at a predetermined position within the apparatus; an urging member for urging the engaging member to engage with the hole; and a disengaging member for selectively disengaging the engaging member from the hole. These parts are arranged to ensure smooth loading and unloading operations on the cassette.
摘要:
A recording and/or reproducing apparatus using a disc-shaped flexible record bearing medium, including a holder for receiving the medium and movable for placing the received medium at a predetermined position for signal recording and/or reproduction, and a pair of sliding members slidable for moving the holder. One of the sliding members has a first cam for operating a pressing member which presses a portion of the medium to mount the same on a rotating spindle, while the other of the sliding members has a second cam for moving a stabilizing member to an operative position at which the stabilizing member stabilizes a portion of the medium near a recording and/or reproducing head when the medium is rotated by the spindle.
摘要:
A recording and/or reproducing apparatus of the kind using a disc-shaped record bearing medium is provided with a stabilizer plate for stabilizing the rotation of the medium; a center core pressing device for pressing a center core which is secured to the medium against a rotatory drive part; and common support member for supporting both the stabilizer plate and the center core pressing device in common with each other, so that the stabilizer plate and the center core pressing device can be arranged in one unit.

In an optical element (B1) prepared by integrally forming, on surfaces of a transparent member, a refracting surface (R2) for receiving a light beam, a plurality of reflecting surfaces (R3, R4, R5) with curvatures, and a refracting surface (R6) for outputting the light beam reflected by the plurality of reflecting surfaces, a reference portion (7) for defining the position of the optical element in a predetermined direction with respect to a Y′-Z′ plane including an incident reference axis (5) and an exit reference axis (5) of at least one reflecting surface of the optical element (B1) is formed on the optical element.
摘要:
A recording or reproducing apparatus for recording or reproducing information by relatively moving a head and a sheet recording medium is disclosed. The recording or reproducing apparatus includes a stabilizing member disposed around the head and arranged to generate pressure which brings the recording medium into contact with the head in accordance with the rotation of the recording medium. The stabilizing member includes a first projection portion having a projection surface projecting toward the recording medium, a second projection portion disposed outside of the first projection portion via a groove portion formed outside the first projection portion, the second projection portion having a projection surface projecting toward the recording medium, and a cut portion formed in a portion of the second projection portion downstream from the head in a direction of rotation of the recording medium, the cut portion being formed by cutting the second projection portion from its surface which confronts the recording medium, and the depth of the groove portion with respect to the recording medium being reduced from the outer portion of the stabilizing member to the inner portion of the same.
