2, and a circuit board 43 is disposed inside such a casing 34. Above placement part 3
6 upper cabinet 41 and lower cabinet 4
2 has a through hole 44 having a substantially cylindrical inner wall surface,
45 are provided to communicate with each other, and these through holes 44 and 45 constitute the above-mentioned through hole 37. Note that in the vicinity of the through hole 37 of the circuit board 43, an insertion hole 46 is formed with a diameter slightly larger than the outer diameter of the inner walls 44 and 45.

The through hole 37 having such a configuration is formed so as to communicate with the operation hole 22 of the computer 13 when the computer 13 is attached. As a result, the operation hole 22 is connected to the through hole 37.
You will be able to see the outside through the . Therefore, when the computer 13 is attached to the printing device 19, the operator can insert the operating rod into the operating hole 22 through the through hole 37 to reset the computer 13 as described above. It becomes possible.

By providing the through hole 37 in the printing device 19 in this manner, the computer 13 can be brought into the reset state. Therefore, as described in the section of the prior art, the printing device 19 is equipped with a reset switch and an accompanying device. There is no need to provide any configuration, and furthermore, the electrical configuration such as circuit wiring is simplified.

The electronic device 13 has a flat, generally rectangular parallelepiped outer shape. An operating portion 28 of the reset switch 24 to be pressed is provided facing the bottom of the operation hole 22. The external electronic device 19 also has a flat, generally rectangular parallelepiped outer shape. The fitting recess 35 is formed from one end 51 in the longitudinal direction of the external electronic device 19 to a midway position 53 of the one side 52 along the longitudinal direction. The stepped portion 38 is
It is formed at an intermediate position 53 of the one side portion 52 of the fitting recess 35, and the connector 39 is provided at this stepped portion 38 as described above. The through hole 37 is formed in the mounting portion 36 of the fitting recess 35, and the through hole 37 is formed near the one longitudinal end portion 51 of the external electronic device 19 and closer to the one side portion 52. Ru. The inner diameter of this through hole 37 is equal to the maximum outer diameter of the operation hole 22.

In this embodiment, the printing device 19 has been described as being connected to the computer 13, but any external electronic device that can be attached to the computer 13 may be used, such as a magnetic cassette tape recording device.

Effects As described above, in the switch structure according to the present invention, a through hole is formed in the casing of the external electronic device, so the actuating part of the electronic device can be operated from the outside while the electronic device is connected. , This makes it possible to change the switching mode of the electronic device. By forming only the through-hole in the external electronic device in this manner, the above-described operations can be realized, so that the mechanical and electrical configuration of the external electronic device is simplified.

In particular, according to the present invention, the electronic device 13 having a flat, generally rectangular parallelepiped outer shape is mounted on the mounting portion 36 of the fitting recess 35 of the external electronic device 19, which has a flat, roughly rectangular parallelepiped outer shape. By placing and mounting the connector 20 of the electronic device 13, the connector 39 provided in the stepped portion 38 of the fitting recess 35
Furthermore, in this mounted state, the through hole 37 of the external electronic device 19 overlaps the operation hole 22 of the electronic device 13, and the inner diameter of the through hole 37 is the same as that of the operation hole 22. Since the diameter is equal to the maximum outer diameter, it is easy to insert the operating rod from the through hole 37 into the operating hole 22 .

The operation hole 22 has a truncated conical inner wall surface,
Since the operating portion 28 to be operated by pressing the reset switch 24 is provided facing the bottom, the operating rod is guided along the inner wall surface of the truncated cone, and it is possible to reliably press the operating portion 28. It is possible. This allows the electronic device 13 to be reliably reset.

Moreover, according to the present invention, the electronic device 13 can be attached to the external electronic device 19 while the electronic device 13 is attached to the external electronic device 19.
The key input section 16 formed on one surface of the electronic device 13 can be operated and the display section 17 can be viewed. It becomes possible to make it happen.

Furthermore, what is important in this invention is that the through hole 3
7 is formed in the mounting portion 36 of the fitting recess 35 of the external electronic device 19 near one end 51 in the longitudinal direction of the external electronic device 19 and closer to the one side portion 52;
Corresponding to this through hole 37, the operation hole 22 of the electronic device 13 is arranged at a corner near the other end in the longitudinal direction, so that the electronic device 13 is attached to the external electronic device 19 in this way. In this state, the electronic device 13 can be easily operated using the operating rod. If the through hole 37 and the operation hole 22 are not provided at the corners of the external electronic device 19, but are provided closer to the center, for example, in order to reset the electronic device 13, The operating rod must be inserted into the through hole 37 and the operating hole 22 at a large angle while the external electronic device 19 and the electronic device 13 remain integrated, resulting in poor operability. The present invention solves these problems.

Furthermore, in the present invention, the connector 2 of the electronic device 13
0 is provided on the side surface 21 at one end in the longitudinal direction, and the external electronic device 1 corresponds to this connector 20.
Another connector 39 is provided on the stepped portion 38 of the fitting recess 35 of No. 9, so that when operating the actuating part 28 by pressing it from the through hole 37 through the operating hole 22 using an operating rod or the like, two connectors 2
The direction in which the connectors 20 and 39 are removed is perpendicular, so there is no fear that the connectors 20 and 39 will come off when the actuating portion 28 is pressed. Therefore, the electronic device 13 and the external electronic device 19 are maintained in an operational state in which they are electrically connected through the connectors 20 and 39.
