  And when taking a customer's order, after taking out from a pocket etc., for example, the main body 41 is hold | maintained with a left hand, and the panel part 43 is rotated to an open position (it is set as a spread state). At this time, the panel unit 43 is opened so that the upper surface 43a of the panel unit 43 and the upper surface 41a of the main body 41 are substantially flush with each other. It is easy to press the cover 63, that is, the membrane switch 42, and the liquid crystal panel 51 of the main body 41 is easy to visually recognize. Thus, it is easy to use because it is easy to see and has good operability.

In addition, the panel unit 43 is opened only when an order is received from a customer, and the panel unit 43 is closed and stored in a pocket or the like except for taking an order. Therefore, the panel unit 43 is frequently opened and closed.
Therefore, when performing a long-time opening / closing operation, mechanical fatigue may accumulate on the pins 44 and 45 and the opening / closing operation may not be performed smoothly.

  In this case, the order input device 40 of this embodiment can separate the main body 41 and the operation panel 47 as separate components, so that only one of them can be repaired or replaced as necessary. Also, in the manufacturing stage, assembly or the like can be performed in a completely independent state. Therefore, unlike the conventional case, it is possible to reduce the cost and labor required for repair and replacement as much as possible.

  Further, since the cable 67 of the operation panel 47 passes through the inside of one pin 45, even if the panel portion 43 is opened / closed, only a simple twisting force acts on the cable 67. Therefore, it is possible to eliminate as much as possible bending with a small radius in a narrow space as in the prior art. As a result, it is possible to reduce the burden on the cable 67 and to suppress the occurrence of defects such as disconnection as much as possible. Accordingly, it is possible to reduce the cost and labor required for the repair and replacement of the cable 67.

  In particular, since an annular ring 70 is provided at the end of one pin 45, it is possible to suppress the friction of the cable 67 as much as possible. Therefore, the burden on the cable 67 is reduced, and the durability of the cable 67 is improved. Can be improved.

  Further, when the main body 41 and the operation panel 47 are integrally fixed, the screw member 65 can be easily fixed only by screwing the female member 53 to the female screw 53, and can be easily unlocked by unscrewing. be able to. Thus, the fixing means 48 can be realized with a simple configuration, and the configuration can be simplified and the cost can be reduced.

  In particular, at the position where the screw member 65 and the female screw 53 are opposed to each other between the protrusion 75 and the notch 76 on the main body 41 side and the notch 77 and the protrusion 78 on the hinge base 46 side, the main body 41 and the hinge 41 are hinged. Since the base 46 can be temporarily fixed, the screw can be reliably engaged, and the usability and ease are improved.

  In addition, since the first wireless communication unit 54 and the second wireless communication unit 66 are respectively provided on the side surface of the main body 41 and the hinge base 46, the control substrate and the membrane are attached by the fixing means 48 along with the detachment operation. Electrical connection or disconnection with the switch 42 can be reliably performed.

  Furthermore, since the pot core sheets 55 and 68 are attached to the side surface of the main body 41 and the outer surface of the hinge base 46 so as to cover the first wireless communication unit 54 and the second wireless communication unit 66, The wireless communication units 54 and 66 are not affected by dust or dust, and a reliable electrical connection can be made. For example, when ordering with the panel unit 43 opened, or when the panel unit 43 is closed and stored in a pocket or the like, the order input device 40 has been exposed to water for some reason. However, the first wireless communication unit 54 and the second wireless communication unit 66 are not affected by water droplets or the like. Thus, the environmental resistance can be improved.

  Similarly, since the cable 67 is embedded in the groove 69 by the filler 71 in the vicinity of both ends of the one pin 45, even if moisture enters from the gap between the panel portion 43 and the hinge base 46, the moisture Does not enter the circuit board 64 or the second wireless communication unit 66 through the groove 69.

  Further, since the embossed sheet 62 is attached to the peripheral edge 61 so as to cover the membrane switch 42 and seal the opening of the cover 60, the cover 60 of the panel 43 is temporarily covered with water or the like. Even if it is applied, moisture does not enter the inside of the cover 60 and the membrane switch 42 is not affected. In particular, when the embossed sheet 62 is pasted, it becomes substantially the same plane as the upper surface 43 a of the panel portion 43, so that moisture does not accumulate on the upper surface 43 a in the panel portion 43. Therefore, the environmental resistance can be improved also from these things.

  In addition, since the cable 67 is laid in the state accommodated in the groove 69, the cable 67 can be made inconspicuous, and the design is excellent.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the second embodiment, the female screw and the screw member are employed as the fixing means. However, the present invention is not limited to this, and it is only necessary that the main body and the operation panel can be detachably fixed.

  In addition, the first wireless communication unit and the second wireless communication unit are employed as the electrical connection means, but the present invention is not limited thereto, and the control board and the membrane switch are electrically connected or removed according to the attaching / detaching operation of the fixing means. It does not matter if it can be disconnected. For example, as in the first embodiment, a concave portion is formed on the side surface of the main body, a first connector portion provided in the concave portion, a protruding portion is formed on the hinge base, and a first portion provided on the protruding portion is provided. You may comprise with two connector parts. In this case, since the first connector portion and the second connector portion are fitted, the connection becomes stronger and a reliable electrical connection can be obtained. At this time, it is preferable to provide a waterproof packing on the outer peripheral surface of the projecting portion so as to contact the inner peripheral surface of the concave portion and seal the inside of the concave portion. By doing so, since water droplets, dust, and the like do not enter the recess from the outside, the environmental resistance is improved.

  Furthermore, in the second embodiment, the order input device is taken as an example of the portable information processing device. However, the present invention is not limited to this, and it is sufficient if it has a panel unit that can be opened and closed with respect to the main body. No (for example, PDA).

  In addition, although only the membrane switch is provided on the operation panel, for example, an information display unit capable of displaying various types of information may be provided.
