[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the entire printer 1. The printer 1 has an internal control board 3 inside a printer case 2, and the internal control board 3 is provided with a standard interface connector 4 of a parallel system as a standard specification. The printer 1 is normally connected to a computer via a standard interface connector 4 provided to be exposed from the inside of the printer case 2, and functions as an output terminal.

The printer case 2 forms the external appearance of the printer 1, has a paper supply port (not shown in the drawing) and a take-out port 5, and has a concave portion 6 formed at an upper portion of a rear portion. Is formed.

FIG. 2 is a perspective view showing a main part of the printer 1. The standard interface connector 4 is disposed in a recess 9 formed on the side surface of the printer case 2 so as to be exposed from the inside of the printer case 2.

As shown in FIG. 1, the recess 6 is formed integrally with the printer case 2 and has a back wall, a side wall, and a bottom wall, and is opened only at an upper side and a side. The components inside the printer case (for example, the internal control board 3) are shielded from the outside by the back wall, the left and right walls, and the bottom wall.

The recess 6 is provided with a cover 7 which can be easily attached and detached by hand. FIG. 4 is a perspective view of the cover 7. A notch 8 is formed on the lower side of the cover 7 so that the notch can be easily cut out to form a notch.

As shown in FIG. 2, a socket 10 provided on an internal control board 3 for setting an IC card 11, a dip switch 12, and a necessary additional interface unit are provided on a bottom wall of the recess 6. A connection connector 13 (the female connector side for connection) for the printer 14 protrudes or is exposed from the inside to the outside of the printer case 2. The connection connector 13 is arranged so that the tangential direction is orthogonal to the tangent direction of the standard interface connector 4.

The necessary additional interface unit 14 is added to connect the printer 1 that uses the parallel system as a standard to a serial computer, and the connection connector 13 connects the additional interface unit 14. This is for connecting to the internal control board 3.

FIG. 3 is a perspective view showing a main part of the printer 1 with the additional interface unit 14 mounted. The extension interface unit 14 has a connector 15 (connector male side) for connecting to the control board 3 and a mounting leg 16 on the lower surface, and a connector 17 for the extension interface unit used for connection to a computer on one side. Have.

In FIG. 2, reference numeral 18 denotes a leg insertion hole. The leg insertion holes 18, 18 are arranged on the left and right sides near the side edge of the bottom wall of the concave portion 6 and communicate with the lower concave portion 9. ing .

Therefore, the cover 7 of the concave portion 6 is now opened, and as shown in FIG. 1, a serial interface unit 14 is inserted into the leg insertion hole 18, and the extension interface unit 14 is inserted into the leg insertion hole 18. Is connected to the female connector 13 on the internal control board 3 and the mounting legs 16 are fixed with screws.

The extension interface unit 14 is attached so that the connection direction of the extension interface connector 17 is the same as the connection direction of the standard interface connector 4 in the recess 6.

Next, when the cover 7 is mounted after cutting the lower side along the cut 8, the printer 1 is provided with a serial connector (a connector 17 for an additional interface unit) on the side of the printer case 2. It can be connected to a host computer whose signal transmission / reception method is serial.

That is, the additional interface unit 14 is easily mounted on the printer 1 without removing the printer case 2 and connected to the internal control board 3.

At this time, even if the cover 7 is removed, the concave portion 6 is formed by blocking the inside of the printer case 2 from the outside, so that the components inside the printer case 2 are not exposed to the outside. In the meantime, the extension interface unit 14 does not contact and damage the components inside the case 2.

Although the embodiment has been described above, in the present invention, the shape and location of the concave portion 6 are not particularly limited as long as the concave portion 6 can accommodate the additional interface unit 14.

The extension interface unit 14 is not limited to the one that adapts the printer 1 to the serial system, and some computers use a unique interface for the interface. By using the interface unit, the types of computers to which the printer can be applied can be expanded.

Further, a cover is not always necessary, and in some cases, a part of the additional interface unit 14 or the function expansion unit mounted in the concave portion 6 functions as the cover and forms a part of the outer shape of the printer case. You may do it.

The additional interface unit 14 may be provided in the form of a board not covered by a case.

The IC card can be replaced with a ROM or a RAM cartridge. Furthermore, in the present embodiment, an example in which the main body has a built-in standard interface and the extension interface unit 14 is mounted in the recess 6 has been described. It can also be configured to attach an interface unit that does not have it.

The form of the connector and whether the male or female side is attached to the additional interface unit are arbitrarily selected.

[Effect of the invention]

 According to the present invention, a concave portion having an inner wall, both side walls, and a bottom wall, which is open only upward and laterally, is formed in parallel with the case above, and is formed on the bottom wall of the concave portion. Since the connector means for connecting the IC card electrically connected to the internal control board is provided so as to be exposed, the IC card is connected to the connector means from above the recess, so that the connection can be easily performed and the internal control board of the printer can be easily connected. An IC card can be connected to it.

According to the configuration of the second aspect, for example, switch means used for switching or the like can be arranged on the bottom wall of the recess together with the connector means for connecting the IC card.
