A printer 5 is provided. A customer-side display 6 is provided on the back of the POS terminal 1 on the customer side.

  Such a POS terminal 1 includes a control unit 7 (see FIG. 3) for processing input information and the like. FIG. 3 is a cross-sectional view schematically showing the configuration of the control unit 7. As shown in FIG. 3, the control unit 7 includes an engine board 8 that is a printed wiring board, a power source 9, an HDD (Hard Disk Drive) 10 that records an OS (Operating System) / application / sales information, and external devices. An I / F board 11 that transmits and receives information, a riser board 12 that relays between the engine board 8 and the I / F board 11, and the like. The riser board 12 is arranged upright in the vertical direction, and the engine board 8 and the I / F board 11 are connected to the riser board 12 so as to be horizontally removable. Further, in the present embodiment, all the HDDs, power switches, and the like wired to the engine board are wired to the riser board 12, so that the engine board 8 can be handled alone.

  On the surface of the engine board 8, electronic components such as a CPU 8 a that centrally controls each part are mounted, and the CPU 8 a is operated to operate equipment via a bus line by a wiring pattern (not shown). A memory 8b or the like that temporarily records an OS (Operating System) or the like is connected and mounted. In addition, a connector 8 c corresponding to the connector 12 a provided on the riser board 12 is provided at the end of the engine board 8.

  FIG. 4 is an exploded perspective view showing the POS terminal 1. As shown in FIG. 4, the main body housing 2 of the POS terminal 1 has a five-part structure including upper and lower panels 2a and 2b, left and right side panels 2c and 2d, and a rear panel 2e. In the portion covered with the left side panel 2c, an opening 13 is formed which is exposed to the outside by removing the left side panel 2c and communicates the outside with the inside of the control unit 7. The engine board 8 is attached to the riser board 12 of the control unit 7 located inside the main body housing 2 so that it can be pulled out from the opening 13.

  The engine board 8 of the present embodiment is detachably attached to the riser board 12 in order to cope with maintenance work such as memory expansion and CPU upgrade. Here, attachment / detachment of the engine board 8 will be described with reference to FIG. As shown in FIG. 5A, in a state where the engine board 8 is inserted into the main body housing 2, the connector 8 c of the engine board 8 is connected to the connector 12 a provided on the riser board 12 of the control unit 7. Yes. As described above, since the connector 8c of the engine board 8 is detachable from the connector 12a of the riser board 12, no cable wiring is required, so the engine board 8 can be connected to the engine board 8 during maintenance work such as CPU upgrade. It becomes possible to improve the handleability. A guide rail (not shown) for guiding the engine board 8 so that it can be pulled out is provided inside the main body housing 2. These guide rails hold the engine board 8 slidably.

  When performing maintenance work such as memory expansion or CPU upgrade, as shown in FIG. 5 (b), the engine is moved from the state shown in FIG. The board 8 is slid along the guide rail.
