Abstract: An optical image is formed in a radiation-sensitive layer (5), by a number of sub-illuminations, in each of which an array of light valves (21-25) and a corresponding array (40) of converging elements (43) are used to form a pattern of spots in the resist layer (5) in accordance with a sub-image pattern. Between the sub-illuminations, the resist layer (5) is displaced relative to the arrays (21-25, 40). The lens array (40) may be tilted with respect to the scan area, such that each resist layer area is scanned by a number of spots. In addition, some spot overlap also occurs in a direction perpendicular to the scan direction. This spot redundancy is utilised by selectively reducing the intensity, or switching off, one or more of the redundant spots so as to alter the position of an edge of a device feature, i.e. “fine tune” it.

Abstract: A casing of a sound record playing apparatus includes of an upper body (1B) and a lower body (1A), and a vibration plate (16) is formed by reducing a thickness of a part of the upper body. An inner surface of the vibration plate is in abutment with a pickup (13) to amplify the vibrations of the pickup. Thus, a conical speaker which has been used conventionary can be eliminated, and the thickness of the recording disk reproducing apparatus is reduced. Expansion member (6) includes cam surfaces (71b, 72b) which force the grooved recording disk (2) away from the pickup (13) when the expansion member (6) is rotated conversely.

Abstract: A turn table having a sound recording disk or record mounted thereon is normally urged upwardly by a spring disposed between a lower surface of the turn table and a chassis of a casing to apply a stylus force to a pickup. A weight member is rotatably and eccentrically supported on an inside mounting plate, and an operating claw having a slant surface formed on a lower surface is fixed to the weight member. When a shock is applied to the weight member externally, the weight member rotates by an inertia force in a plane perpendicular to a rotary shaft of the turn table. As a result, the operating claw on the weight member moves toward an upper end of the rotary shaft. The slant surface of the operating claw rides over the upper end of the rotary shaft to downwardly press the rotary shaft together with the turn table. Thus, the stylus force of the pickup is released.

Until the record is positioned on the record holding portion of the player, the reproducing stylus is disposed in a recessed portion or an opening so as to be shielded from the outside. When the record is positioned and fixed to the record holding portion, a projecting rod attached to the center of the record pushes a pusher placed about the center pin of the player such that the pusher advances along the center pin. By a wedge action given by an inclined face of the head of the pusher, a tone arm carrying the reproduction stylus is pushed outward so that the reproduction stylus can be positioned to confront the recorded face of the record. By virtue of this construction, the design defect of injuries to an operator's body by an exposed stylus can be entirely prevented.

Abstract: A continuous repeating type simplified sound reproducing device including on its casing, a fixed locking lever having a locking face parallel to the plane of rotation of a record disc and a rotating locking lever on the record disc which rotates together with the record disc and is able to enter under the locking face of the fixed locking lever only when the record disc is placed at its retracted position. At least one of the locking faces of the two locking members are arranged to have a face length corresponding to the angle of rotation sufficient to maintain the record disc at its retracted position until the record disc has completely returned to the starting point of sound reproduction. By virtue of this construction, satisfactory returning motion of this continuous repeating type sound reproduction device can be assured by a comparatively simplified construction.

Abstract: The sound-reproducing device for playing the record disc has a number of selection poles corresponding to the member of recorded grooves and a stylus force releasing wheel normally urged to a specific direction but which rotated by one of the selection poles to release stylus force on a pickup. The stylus force releasing wheel includes a locking arm confronting the back face of the selection pole in an advanced position for pushing the inclined face of the releasing wheel. Each of the selection poles has a jaw which catches the locking arm and prevents the selection pole when in an advanced position from retraction.

A record disc unit includes a turn table and a record face member disposed in a stacked but axially separable arrangement. A stopper pin is disposed on the record face member.

Abstract: A winding knob and a winding wheel are supported around a center shaft and are rotatable together in the direction of winding and are also axially movable together without causing axial movement of the center shaft by pushing ahead the winding knob. Between a record disc being urged toward a pickup and movable along the center shaft and the winding wheel, there is provided a slippage preventing post which is placed into engagement with a retaining piece provided on the reverse face of the record by operator's winding motion while depressing the knob but is released from such engagement by the operator's subsequent depression of a starting post and the movement of the record disc away from the pickup. When the record disc returns to its initial position by the operator's releasing of depression, the slippage preventing post moves out of engagement with the locking piece.

Abstract: A one-way clutch is provided between a constant torque spring motor and a turn table. A locking projection in the one-way clutch acts to engage, through a rotatable locking piece, a locking face facing to the opposite direction of rotation of the record disc for reproducing sounds.By virtue of this locking driving force of the constant torque spring motor is transmitted to the turn table, while in the winding operation, applied force can be released by the slant face inclined toward the direction of rotation of the record disc and thereby can be disconnected with the turn table. Due to this simple construction, a one-way clutch applicable to this kind of constant torque spring motor for use in a sound reproducing device can be easily fabricated and assembled. In order to prevent any harmful frictional slippage of the pickup on the face of record disc by reverse turning of an indexing disc, another one-way clutch of similar construction is disposed between the indexing disc and the face plate.

A reverse slippage restraining post or plunger is disposed between the winding wheel and a record disc axially movable along the center shaft. The record disc is resiliently urged toward a pickup.The reverse slippage restraining post or plunger engages a locking piece provided on the record disc when it is pushed forward by the winding wheel when the winding knob is pushed forward in its first winding, while it is pushed back when the record disc is moved away from the record disc by the depression of a starting post, and is released from the engagement with the locking piece to permit rotation of the record disc when the record disc reverts back to its undepressed position when the depression on the start post is released.

Abstract: A winding string, when stretched tight, will lift a speaker unit which applies a stylus pressure to a pickup so that the pickup is allowed to reverted back to the starting point of sound reproduction. The stretched string will also lift a plunger carrying a stopper block to axially advance so as to be in engagement with a retainer piece disposed on the record disc.The plunger is normally urged by a first spring toward a direction in that the stopper block may retract away from the engagement with the retainer piece disposed on the record disc.The advanced position of the plunger, at which the stopper block engages the retainer piece is sustained by a lever movable in a see-saw like swing motion.The lever is actuated by the movement of an intermediate starter member initiated by the depression of any one of the selective starter rods provided in number corresponding to that of recorded grooves and thereby releases the record disc from its temporarily stopped condition.

The center shaft as a center of rotation of the record disc is normally biased by a spring toward retracted direction and engages the locking bars through a manipulating member.
