Abstract: To prevent a printing head not placed on a cleaning placing unit from being cleaned and prevent contamination of an ambient environment by cleaning liquid. An ink jet recording system includes a placement detecting unit configured to detect that a printing head 1 is placed on a cleaning placing unit 200. The placement detecting unit is configured to, when detecting that the printing head 1 is placed, transmit a signal based on placement confirmation for the printing head 1 to a controller connected to the printing head 1 placed on the cleaning placing unit 200.

Abstract: In an optical information reader, an entire size is reduced while a space for accommodating an imaging unit, a space for accommodating a cable of an external interface, and a space for accommodating plural boards in which circuits of a signal processing unit are accommodated are secured. An entire size of a housing is determined based on sizes of a main board and an imaging unit to realize an optical information reader having a minimum shape. The main board has the largest area as a board, and a CPU and a memory are mounted thereon. The imaging unit includes a camera module, a lighting LED unit, and a marker. The main board is disposed near an internal wall of a housing. Other functions are functionally divided into sub-boards and disposed around a frame body, and a connection portion to the cable is accommodated in the frame body to achieve miniaturization.

Abstract: In the sliding portable telephone of the present invention, on the surface of the base housing, a photoconductive member is placed along a boundary line between a first surface region which is exposed when the slide housing is placed at the open position and a second surface region which is covered by the slide housing, a light emitting element for emitting light toward an end part of the photoconductive member on the second surface region side is arranged inside the base housing. The slide housing is provided with a reflecting plate reflecting light which has passed through the photoconductive member toward an end part of the photoconductive member on the first surface region side at a position opposed to a surface of the photoconductive member when the slide housing is placed at the open position.

Abstract: The invention provides a portable terminal device of the foldable type wherein a manipulation-side cabinet and a display-side cabinet each comprises a front cabinet segment and a rear cabinet segment joined thereto. The manipulation-side cabinet has its front cabinet segment connected at an end portion thereof to a hinge mechanism and has its rear cabinet segment engaged with the front cabinet segment thereof. The display-side cabinet has its rear cabinet segment connected at an end portion thereof to the hinge mechanism and has its front cabinet segment engaged with the rear cabinet segment thereof.
