It is characterized in that it is arranged near the front end of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a case opening / closing mechanism in a POS machine, and more particularly to a mechanism for opening / closing a part of the case when the ink inside the case is replaced due to wear. In this specification, a POS machine includes a printer with an ink ribbon and a keyboard section in equipment used for a POS system, such as a POS store controller, a satellite machine of a POS terminal, and a master machine. We shall refer to those who

[0002]

[Prior art]

 As shown in FIG. 3, for example, a case opening / closing mechanism in a conventional POS terminal has a printer 2 arranged in the upper half of the inside of a case main part 1 and a hinge part 3 on the back side as an axis center for a printer cover. 4 has a structure in which the ink ribbon 5 is replaced by unfolding the ink ribbon 5 behind as shown by the chain line, and as shown in FIG. It is provided so as to be located below the portion 6, and the ink ribbon 5 is exchanged with the hinge portion 3 at the front end as an axis and the keyboard portion 6 standing up as shown by a chain line. There is something.

[0003]

[Problems to be solved by the device]

 The former of the above-mentioned conventional structures, i.e., the structure of deploying the cover behind, not only makes the terminal itself large, but also needs to secure a space behind the machine body. There is a disadvantage of being restricted. In the latter case, that is, the structure in which the keyboard part is erected, the terminal itself can be made small, but as shown in the figure, the keyboard part is erected at the front end of the main part of the housing. Since the ink ribbon must be replaced in this condition, the workability is extremely poor.

Therefore, an object of the present invention is to provide, at a low cost, a casing opening / closing mechanism that can downsize the body of a POS machine equipped with a printer with an ink ribbon and can easily replace the ink ribbon. Especially.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a printer in a main body of a housing so that an ink ribbon portion of the printer is located below a rear end of a board-shaped keyboard portion. The ink ribbon can be exchanged by exposing the ink ribbon part by opening and closing, and as a mechanism for opening and closing the key board part, at least a pair of left and right comparison board parts The chassis can be opened and closed while being connected to the main part of the chassis by an extremely short link, and the key board part can be moved upwards and backwards while moving upward and downward along an arcuate trajectory. It is characterized in that it is arranged near the front end of the main part.

[0006]

[Action]

 From the normal use state in which the keyboard part covers the ink ribbon part of the printer, the keyboard part is pulled upward while pulling the keyboard part up, so that the keyboard part is left and right in a pair. Under the condition that it is supported by the link of the printer, part of it is transferred to the front so that it protrudes from the front end of the main part of the housing, and as a result, the ink ribbon part of the printer is exposed and you can replace the ink ribbon. The hit keyboard part does not get in the way.

【Example】

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

As a POS machine to which the case opening / closing mechanism of the present invention is applied, for example, as shown in FIGS. 1 and 2, a disc-shaped keyboard for operation is provided on the upper front half of the case main body 11. In addition to installing the printer section 12 in a diagonally upward direction, the display section 13 is provided in a diagonally forward direction in the upper half of the second half, and the printer 14 has an ink ribbon 15 in the inside of the main casing section 11 of the keyboard section 12. Adopt a type that is provided so as to correspond to the lower part of the rear end and that has the necessary electrical components (not shown).

As a special construction of the present invention for the above-mentioned type of POS machine, as shown in detail in FIGS. 1 and 2, for example, two pairs of the key board portion 12 are provided near the left and right ends thereof. The short links 16, 16 and 17, 17 are connected to the main part 11 of the housing, whereby the keyboard part 12 is moved upward in the arc-shaped locus while facing upward and the ink in the printer 14 is transferred. An opening near the center of the main casing 11 corresponding to the upper portion of the ribbon 15 can be opened over a distance of about twice the length of the links 16 and 17, and the ink ribbon 15 of the printer 14 can be opened from this opening. Make sure to remove and replace.

As for the link connecting the housing main portion 11 and the keyboard portion 12, only one pair of the front links 16, 16 or the rear links 17, 17 may be used. However, it is desirable to provide two pairs of front and rear as in the illustrated embodiment.

[0011]

[Effect of device]

 As described above, according to the present invention, the printer is provided in the main body of the housing so that the ink ribbon portion of the printer is located below the rear end of the keyboard portion, and the printer of the keyboard portion is provided. In a POS machine in which the ink ribbon portion can be exposed by opening and closing and the ink ribbon can be replaced, the key board portion is connected to the main body portion of the housing by at least a pair of left and right links. In addition, since the key board part is configured to open and close while moving upward and backward in an arcuate locus while facing upward, this makes it possible to open the keyboard part with a simple structure. The ink ribbon can be stably opened and closed without hindering the replacement work, so that the ink ribbon can be easily replaced when necessary.
