Description

[0001]
[Industrial applications]
The present invention relates to a small multi-pose printer that can be placed vertically and horizontally.
[0002]
[Prior art]
In order to configure a printer that occupies as little space as possible, taking into account the storage space for recording paper to be supplied and the placement space for ejected recording paper, the storage space for recording paper is provided on the bottom of the printer, It is preferable from an operational point of view that the recording paper pulled in from the upper side of the printer is discharged to the rear of the upper surface of the printer, and that the printer can be used vertically or horizontally depending on the arrangement. Is desirable.
[0003]
However, when the printer is configured in such a manner, the recording paper discharged upward is scattered back and forth due to its own weight when the printer is placed in a horizontal position, which causes a problem of disposing the recording paper. For this reason, it is necessary to use an appropriate paper output tray and support legs, and as a result, these parts become obstructive at the time of transfer, or one of them becomes unnecessary depending on the vertical or horizontal arrangement, so that these parts are not required. Another problem arises: it will be lost soon.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of such a problem, and an object of the present invention is to stably maintain the printer body and the discharged recording paper by a single member that can be stored regardless of whether the printer is installed vertically or horizontally. It is an object of the present invention to provide a new small printer capable of supporting.
[0005]
[Means for Solving the Problems]
That is, since the present invention to solve the above problems, in the form of small printer for discharging the recording sheet fed from the lower than the upper rear surface, while providing the holding portion on the rear end surface center of the printer main body, making a printer A plate-shaped stand / stacker member having a function of holding the recording paper in a displaced position and a function of receiving the discharged recording paper is provided with a long hole extending from one end in the longitudinal direction to the center, and the stand / stacker member has two functions. in order to retain the three positions of the storage position, in which to attach freely rotatably and slidably in the holder the stand-cum-stacker member through the long hole.
[0006]
【Example】
Therefore, embodiments of the present invention will be described below.
The drawings all show one embodiment of the present invention.
In the figure, reference numeral 10 denotes a casing of the printer main body 1. Inside the casing 10, a paper transport path 2 extending in the thickness direction is formed in the inner part with the operation side facing the front. The paper feed roller 3, the paper feed roller 5, and the platen 6 are disposed in this order from below, and a carriage 8 running on a carriage guide 7 and a ribbon cartridge 9 are disposed on the platen 6 so as to face each other. Have been.
[0007]
The casing 10 is formed, for example, in a thin box shape having a width slightly larger than the width of the A4 size. A shallow concave portion provided on the lower surface and extending in the longitudinal direction as a whole is formed as a concave portion 11, and is formed as a tray storing concave portion 16 for storing a sheet feed tray 25 described later.
[0008]
The above-mentioned stand / stacker board 20 is vertically extended so as to be able to receive the recording paper discharged from the paper discharge port 18 by protruding at right angles to the upper surface side when the printer main body 1 is placed horizontally. When the printer 20 is placed on the lower side, it protrudes at a right angle to the lower surface side to suppress the printer body 1 from falling down. The board 20 is provided with an elongated hole 21 extending from the base end to the center in the longitudinal direction. The casing is pivotally slidably and rotatably connected to the support stud 12 provided at the center of the rear end face of the casing via the elongated hole 21.
[0009]
On the other hand, the support stud 12 described above is erected at the center of the board storage recess 11 at the rear end face of the casing for housing the board 20, and the support stud 12 is gradually lowered toward the lower surface in the vicinity of the lower surface side. An inclined recessed portion 13 having a triangular cross section is provided so as to be deep, and a base end portion is inserted into this portion so that the board 20 can be erected and supported in a state inclined backward. Have been.
[0010]
On the other hand, the storage recess 16 provided on the lower surface of the casing 10 has its leading end reaching the recording paper lateral insertion slit 17 which is fully opened in the width direction of the casing 10, where the recording paper is stored. The paper feed tray 25 is mounted so that it can be opened and closed in a semi-open manner with the shaft 4 of the paper feed roller 3 as a fulcrum, and the leading end faces the slit 17.
[0011]
A sub-tray 27 is attached to the paper feed tray 25 along two guides 26 provided on the lower surface thereof so that the sub-tray 27 can be pulled out to the near side. The end is hung and supported by a key-shaped bent portion 28 provided at the front end.
[0012]
In the drawing, reference numeral 14 denotes a locking hole for engaging with the locking dowel 22 provided on the stand / stacker board 20 to lock the board 20 in the storage position. Reference numeral 19 denotes a stopper for determining the position of the printer body, and reference numeral 19 denotes a lid that covers the upper surface of the printer main body 1.
[0013]
The printer main body 1 configured as described above accommodates the paper feed tray 25 in the tray accommodating recess 16 and sets the stand / stacker board 20 parallel to the board accommodating recess 11 when not in use or when transporting. So that it is positioned and accommodated in the recess 11 by the locking hole 14 and the stopper 15.
[0014]
In this state, when the printer body 1 is to be used sideways, the stand / stacker board 20 is rotated upward by 90 ° from the housing state shown by the two-dot chain line in FIG. 1 and pulled up.
As a result, the base end of the board 20 enters the board slanting recess 13 having a triangular cross-section, and tilts rearward as shown in FIGS. 1 and 2. The recording paper discharged upward from 18 is placed on the stand / stacker board 20 as it is.
[0015]
When the printer body 1 is used vertically, the stand / stacker board 20 is pulled out to the lower side in advance, and the printer body 1 is placed upright. As a result, as shown in FIG. 3, the printer main body 1 is prevented from falling down to the lower surface side. In this state, the paper feed tray 25 is opened halfway as necessary, and the required number of recording paper Is loaded and the recording is performed, the recording paper is drawn into the paper transport path 2 at a shallow angle by the opening of the paper feed tray 25, and the paper is fed more smoothly. Further, when writing on thick paper such as a postcard, as shown by an arrow in FIG. 2 can be fed straight to the platen 6. Similarly, when the A3 recording paper is used horizontally, for example, the slit 17 extending over the entire width of the casing 10 is used. The recording paper may be inserted sideways here.
[0016]
According to the present invention as described above, the stand-cum-stacker member provided with elongated holes, two positions and the storage position resulting in the function of receiving the recording sheet discharged the function of holding in a posture standing printer body in order to retain the three positions, since the attaching freely rotatably and slidably in the holder, upon the aft houses the printer body rear face, transversely printer when not in use and receiving Ru member discharged recording sheet, also readily made to correspond to the various use forms a single member without the need for special member collapse as proof tool member when made a printer, small The printer can be made more functional and simpler.
