Abstract: A deck mechanism of a headphone stereo which is capable of minimizing a tension working on a belt and of controlling a rotation torque transmitted to a reel in an FF or REW mode by transmitting a driving force of a driving motor by a power transmission gear unit, includes a power transmission gear unit for transmitting a driving force of the driving motor, a mode selector for transmitting the driving force transmitted by the power transmission gear unit according to a selected mode, a reel driver for driving a reel according to the selection of the mode selector, a power transmission idler unit moving according to the play direction of the reel driver, and a capstan driver for driving a capstan through a belt transmission by a selective engagement of the power transmission idler unit.

Abstract: A tiltable, rotatable and detachable LCD view finder for a camcorder that enables a user to easily take pictures while viewing the LCD viewfinder. The viewfinder can be rotated 360.degree. and tilted 180.degree. relative to the upper surface of the camcorder body. The viewfinder system includes: an LCD (Liquid Crystal Display) viewfinder; a downwardly opened recess formed on a predetermined edge portion of said LCD viewfinder and having a first side wall, a second side wall, a back wall and a semicircular end; and a tiltable, rotatable and detachable compound joint assembly member fitted into said recess for tiltably, rotatably and detachably connecting the LCD viewfinder, whereby the LCD viewfinder can be tilted, rotated, and detached relative to the camcorder body.

Abstract: A reel disk for a small cassette is simplified in cap reel structure therein so that number of parts thereof are reduced and assembly work becomes easy. The simplified cap reel is of elastic body and has elastic locking pieces that are united as one body with said cap reel and is jointed with a hub of a cassette tape for delivery of rotation force.
