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 headis placed on a cleaning placing unit. The placement detecting unit is configured to, when detecting that the printing headis placed, transmit a signal based on placement confirmation for the printing headto a controller connected to the printing headplaced on the cleaning placing unit

Ink jet recording system

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.
