Reference numeral 8 denotes a protrusion provided on the back side of the lid 5 in a position corresponding to the power off key 4;
When the lid 5 is closed, the power off key 4 is pressed to open the power circuit of the microcomputer main body 1. Reference numeral 9 denotes a main body side connector provided on the left side of the microcomputer main body 1 for transmitting and receiving signals. 10 is an external device for the microcombi coater main body 1 configured as described above, and a printer device 11 is located on the left side of this device.
and an external storage device 12 are attached. Reference numeral 13 denotes a microcomputer main body 1 provided on the right side of the external device 10.
There are four storage parts 13 for storage, and at the rear of the four storage parts 13 there is an inclined surface part 13a for receiving the lid 5 of the microcomputer main body 1.
An insertion opening 13b for inserting the microcomputer main body 1 is formed at the right end. Reference numeral 14 denotes a device-side connector provided at the left end of the storage recess 13 in a position corresponding to the main body-side connector 9 of the microcomputer main body 1, and this device-side connector 14 is connected to the main body-side connector 9. 15 is an inclined surface portion of the storage recess 13, 13a
This regulating portion 15 is provided at the right end portion of the regulating portion 15, and the regulating portion 15 has a projecting piece portion 15a extending integrally to the upper end portion of the front edge.

Therefore, when the microcomputer main body 1 is connected to the external device 10 (see FIG. 1), when the lid 5 of the microcomputer main body 1 is opened, the right end of the M5 comes to the inner surface of the regulating part 75. The rightward movement of the microcomputer main body 1 is regulated as they face each other, and when the -10,000 N5 is closed, the lid 5 is in a state not facing the regulating part 15, and the upper surface of the indigo 5 is below the protrusion part 15a. Since the microcomputer main body 1 is located at the position (see second N: dotted chain line), rightward movement of the microcomputer main body 1 is permitted. Therefore, the microcomputer main body 1 and the outer F! To disconnect from the AM device 10,
First, the lid 5 is closed. Then, as N5 is closed, the power off key 4 is pressed by the tip of the protrusion 8 on the back side of each 5, and the power circuit of the microcomputer main body 1 is opened. After that, when a force is applied to the microcomputer main body 1 to pull it out to the right along the storage recess 13,
The connection between the main body side connector 9 and the device side connector 14 is disconnected, and the microcomputer main body 1 passes under the protruding piece 15a of the regulating portion 15 and is pulled out to the right side of the external device 10.

On the other hand, when connecting the microcomputer main body 1 and the external device 10, first close M5, and then insert the microcomputer main body 1 by sliding it into the storage recess 13, contrary to the above. to connect the main body side connector 9 to the device side connector 14 of the external device 10. After connecting in this way, open M5 and power on key 3.
When is pressed to close the power supply circuit, signals can be exchanged between the microcomputer main body 1 and the external device 10. In this way, the microcomputer main body 1 and the external device 1
0, if the lid 5 is in an open state, the left end of the lid 5 will come into contact with the regulating part 15, preventing the microcomputer main body 1 from being inserted into the housing part 13. Ru.

According to the above configuration, when the power of the microcomputer main body 1 is on, the lid 5. is in an open state. Therefore, even if an attempt is made to connect or disconnect the microcomputer main body 1 from the external device 10 while the power is on, since the external device 10 is provided with the restricting portion 15, the opened lid 5 will not hit the restricting portion 15. Disconnection of connected components that are in contact with each other is clearly prohibited. As a result, when the microcomputer body 1 is connected to or disconnected from the external device 10, M5 must be closed. Therefore, when M5 is closed, the power off key 4 is automatically pressed by the protrusion 8. Since the power supply circuit of the microcomputer main body 1 is opened, the connection configuration is changed when the microcomputer main body 1 is disconnected.
It is possible to reliably prevent the user from forgetting to turn off the power, and it is also possible to reliably prevent a program from erroneously creating or running out of control due to forgetting to turn off the power, and from causing damage to the built-in IC.

In particular, in this embodiment, the M5 can be held at any rotation angle, and a liquid crystal display section 7 that can display multiple lines of characters or figures is installed on the back side of the M5, so even if it is a doll display. Regardless, the whole can be made compact, and by adjusting the rotation angle of the A6 lid 5, the direction of the liquid crystal display section 7 can be set to an angle that is easy to see, and it is possible to prevent indoor lighting etc. from being reflected on the surface of the liquid crystal display section 7. Furthermore, since M5 is blocked when carrying,
The liquid crystal display section 7 can protect the power supply device 2, and also prevent battery consumption due to forgetting to turn off the power or pressing the power on key 3 by mistake.

In this embodiment, the regulating section 15 is provided on the external device 10 side, but the present invention is not limited to this. The regulating section is provided on the lid 5, and the regulating section is locked to the external device 10 when the lid 5 is opened. It is also possible to do so.
