摘要:
A color thermosensitive recording sheet is formed by sequentially laying a cyan thermosensitive coloring layer, a magenta thermosensitive coloring layer, and a yellow thermosensitive coloring layer on a base. On this color thermosensitive recording sheet, a color image is printed with a thermal head by a three-color image sequential printing method. Each thermosensitive coloring layer develops color by a bias heating and an image heating. A bias heat energy slightly short of the coloring of a thermosensitive coloring layer to be colored and an image heat energy corresponding to the coloring density are used. A blank area is formed in the background of a binary image such as characters and line drawings. A blank frame is formed surrounding a half tone image area, Rearing elements facing such a blank area and a blank frame make a bias heating at a heat energy approximate to the magenta bias heat energy, for printing to the lowermost cyan thermosensitive coloring layer. The heating elements for printing the binary image or the half tone image make the bias heating at the cyan bias heat energy. For a postcard having a half tone image area and a binary image area juxtaposed with the half tone image area, the first several lines of the binary image area are inhibited from being printed for yellow and magenta, and the cyan image is dummy-printed at the magenta bias heat energy, so as to avoid a color registration shift of the binary image.

A contactless digital key switch is provided which comprises a plurality of printed circuit substrates each having a predetermined number of magnetic sensor chips longitudinally arranged thereon in spaced relation, the printed circuit substrates disposed in the form of polygon prism with the magnetic sensor chips facing inwardly, an actuating key member having one or more permanent magnets longitudinally arranged therein in spaced relation and in coded form, a rotary member adapted to receive the actuating key member and rotate with the same within the polygon prism defined by the printed circuit substrates, and means drivingly connected to the rotary member for permitting rotation of the rotary member with a snap action and holding the rotary member in a position where the permanent magnets face to the corresponding magnetic sensor chips on one of the printed circuit substrates every time the rotary member is rotated by a predetermined angle, whereby a coded signal corresponding to the permanent magnets arranged in coded form can be provided every time the actuating key member is rotated by the predetermined angle.
摘要:
A miniature slide switch assembly in which a fixed base member, has a pair of opposite longitudinal side surface, molded out of any suitable insulating material. Each of the side surface is provided with a pair of recesses. At least two adjacent molded fixed contacts are disposed in the longitudinal direction of the base member. A movable casing member slidably rides on the base member in such a manner that it can slide in the direction of the array of the fixed contacts, each of opposite side surfaces of the movable casing member having a resilient detent bar. The resilient detent bar is provided with, at the top end thereof, a finger capable of being alternately snap fitted into the recesses, and an electrically conductive inversed U-shaped strip is accommodated in the cavity of the movable casing member. This strip can slide over the adjacent fixed contacts in accordance with the movement of the movable casing member, whereby, when the conductive strip is in the first position, it bridges two adjacent fixed contacts, and when the conductive strip is in the second position, the bridging of the conductive strips between two adjacent fixed contacts is broken.
摘要:
A miniature switch assembly comprising a base member having a plurality of parallel finned projections, a pair of contact members each having a plurality of contact terminals being fixed on both sides of the base member, respectively, a plurality of lever wheels being disposed between the adjacent finned projections, and a housing having a plurality of partition walls for accommodating the base member with the contact members and the lever wheels, wherein the lever wheels each having conductive plate perform the switching action in a manner that the conductive plate slides over the contact terminals. A locking member is also provided for locking the lever wheels. Preferably, a dust cover is provided for protecting the switch assembly from dust or mechanical injuries.
