Description of the Related Art Conventionally, as a small electronic device, there has been known a hard case type calculator in which a main body case is openably and closably covered with a lid case. With this calculator, when the lid case is opened and held by hand, the lid case swings up and down during use when the lid case is opened at about 180 °. And use it. In such a hard case type calculator,
As shown in FIGS. 7 and 8, the main body case 1 and the lid case 2 are connected. That is, the main body case 1 is provided with a liquid crystal display section 3 and a key input section 4, and a cutout recess 5 is formed at an intermediate portion at one end of the main body case 1. The lid case 2 is for opening and closing the upper surface of the main body case 1 to protect the liquid crystal display unit 3 and the key input unit 4, and is made of a hard synthetic resin. A rib 6 is formed in a frame shape around the inner surface of the lid case 2 (that is, the surface facing the main body case 1). The rib 6 is for preventing the inner surface of the lid case 2 from contacting the key input section 4 when the lid case 2 is closed. At the end of the lid case 2, a notch recess 7 is formed corresponding to the notch recess 5 of the main body case 1. Then, as shown in FIG. 7, in a state where the main body case 1 and the lid case 2 are opened at almost 180 °, each of the notched recesses 5 and 7 of the main body case 1 and the lid case 2 has A plurality of flat connecting pieces 8 are arranged. The connecting piece 8 and the main body case 1 are provided with connecting pins 9, 9 at both ends of the notch recess 5 and opposite end faces of the connecting piece 8.
Are connected so as to be rotatable. The connecting piece 8 and the lid case 1 are rotatably connected by connecting pins 10 and 10 at both ends of the notch recess 7 and opposite end faces of the connecting piece 8 opposed thereto. As a result, the main body case 1 and the lid case 2 are connected to be openable and closable by the connecting piece 8 and the connecting pins 9 and 10.
