Abstract

(57) [Problem] To mount a circuit board so that work such as replacement can be easily performed without increasing the occupied area. An area occupied by a printer is provided by using a lower part of a paper discharge tray or a paper supply / discharge tray 8 attached so as to be connected to a paper transport path 2 of a flat bed type printer as an arrangement portion of a circuit board 15. That can be mounted without substantial enlargement and that allows easy replacement of circuit boards and the like.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a printer, and more particularly, to a printer having a feature in a place where a circuit board is provided.

[0002]

2. Description of the Related Art A so-called flatbed type printer in which a paper feed roller, a platen, or a paper discharge roller is disposed so as to face a horizontal paper conveyance path before and after a recording / writing section, and to improve printing accuracy. On the other hand, this type of printer, on the other hand, requires that the circuit board be disposed below the paper transport path, so when replacing the ROM or the circuit board, the outer case must be used each time. Since it is necessary to remove each member on the paper transport path such as the paper transport mechanism and the print transport mechanism, there is a great problem in assemblability and maintainability. The arrangement has a problem in that the area occupied by the printer is increased.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem.
An object of the present invention is to provide a new printer capable of easily replacing a circuit board without increasing the size of the apparatus.

[0004]

That is, in order to achieve the above object, the present invention relates to a printer in which a paper transport path before and after a recording / writing section is substantially horizontal.
By configuring the lower part of the paper board detachably mounted on the printer body to be connected to the paper transport path as a circuit board mounting part, the dead space created below the paper board can be used as the circuit board mounting part. Thus, the replacement of the circuit board and the like is facilitated without increasing the occupied area.

[0005]

Embodiments of the present invention will be described below. The drawings show an embodiment of the present invention.

The printer main body denoted by reference numeral 1 has a paper feed roller 3 and a platen roller 4 along the paper transport path 2 which is horizontal from one end on the operation side, that is, the left end in the figure.
And a paper discharge roller 5 are arranged in order. Above the platen roller 4, a recording head 6 running along a carriage guide 7 arranged in a direction parallel to the axis is arranged. At one end on the operation side of the printer body 1, a paper table, that is, a paper discharge tray or a paper supply / discharge tray 8 is detachably attached along the paper transport path 2.

On the other hand, reference numeral 10 in the figure denotes a shield case formed so as to house two circuit boards 15 therein. The shield case 10 is located immediately below the mounting position of the sheet supply / discharge tray 8. The space provided on the operation side of the printer main body 1 without substantially increasing the occupied area of the printer main body 1 by utilizing the dead space of the printer main body 1 and the upper open space formed by removing the paper supply / discharge tray 8 is utilized. Thus, the circuit board 15 accommodated in the shield case 10 can be replaced or the ROM can be replaced.

[0008] In the figure, reference numeral 11 denotes a shield case 1.
0 is a shield cover rotatably provided with a fulcrum pin 12 as a fulcrum so as to cover an upper open surface of the paper feed tray 8.
Legs standing on the shield case 10 to support the
6 denotes a flexible cable connected to the circuit board 15, and 9 denotes a printer main body.
2 shows a cover for covering the operation-side open end of FIG.

In the printer constructed as described above, the shield case 10 accommodating the circuit board 15 is connected to the sheet supply / discharge tray 8.
, The shield case 10 can be arranged without substantially changing the occupied area thereof, and at the same time, the upper open space formed by removing the paper supply / discharge tray 8 can be used. As a result, the replacement work of the circuit board 15 and the like can be easily performed.

In this embodiment, the shield case 1
0 can be stored below the operation side of the printer main body 1,
In other words, in a printer in which a paper discharge tray is provided on the right end side of the drawing, a dead space formed below the paper discharge tray may be used as a space for disposing the shield case 10 according to a preferred embodiment of the present invention. One.

[0011]

As described above, according to the present invention, the circuit board and the like are provided below the paper supply / discharge tray provided for connection to the paper transport path in the horizontal direction. Utilizing this dead space makes it possible to arrange a circuit board of this kind having a relatively large area without substantially increasing the dead space, while simply removing the paper supply / discharge tray and opening the upper side. By,
Workability such as the attachment and detachment of the circuit board and the replacement of the ROM can be greatly improved, and the cable can be designed so that it can pass under the printer main body with the circuit board. Further, the degree of freedom for the user in the system layout can be increased.
