Abstract: An information terminal device includes a first housing and a second housing slidably connected to each other with a connecting mechanism and that is changeable in state between a closed state in which the two housings overlap each other and an open state in which the two housings overlap each other by an area smaller than in the closed state. The information terminal device includes an elastic sheet component attached to a surface of the second housing that faces the first housing and having a protrusion protruding towards the first housing, and a biasing component that biases the protrusion towards the first housing so as to cause the biased protrusion to be elastically in contact with the first housing when the information terminal device is in the closed state.

Abstract: An ultrasonic printing method by which recording of a high resolution can be achieved. In the ultrasonic printing method, some or all of a plurality of ultrasonic oscillators are selectively driven in such phases that a difference in phase at a predetermined point between a reference ultrasonic wave from one of the selected ultrasonic oscillators and another ultrasonic wave from any other one of the selected ultrasonic oscillators is equal to or less than one-fourth a wavelength of the ultrasonic waves in a transmission medium for the ultrasonic waves from the selected ultrasonic waves to the predetermined point. The ultrasonic printing method can be applied to various printing apparatus for which recording of a high resolution is required.

Abstract: A divisional step dot printing device for a wire dot printer in which a plurality of dot pins of the dot printing head is divided into a plurality of groups of a sequence of dot pins and is driven in a sequence of divisional dot printing steps. Each of the divisional dot printing steps is carried out by a combination of groups of dot pins which substantially cover the center line of the platen.

Abstract: An impact wire-dot printing head comprising a frame (4, 15, 32); impact dot printing mechanisms, each comprising an armature (1) having an outer end pivotably supported by the frame means, an electric magnet for attracting the armature (1) an impact dot-wire (3) being driven in an axial direction thereof by the armature (1). The armatures (1) are radially arranged on an arrangement face perpendicular to the direction in which the dot-wires are driven, and the outer end of each armature (1) is provided with a projection (5) protruded perpendicularly to the arrangement face and in a direction opposite to the direction in which the dot-wire (3) is driven. The frame is provided with slots (6) for loosely accommodating the projections (5) of the respective armature (1), so that a movement of the armature (1) in the arrangement face is restricted.
