Unit mounting part 44b formed in a character shape
And is substantially L-shaped when viewed from the side. On the upper surface on the rear side of the roll paper mounting portion 44a,
A holding member 5 for sandwiching and supporting the shaft portion of the roll paper 50
1, 51 are attached. Unit mounting part 44b
On the front side, a print control unit 45 is attached, and on the rear side thereof, an insertion slot 52 is formed to receive the leading end of the paper pulled out from the roll paper 50, and the leading end of the roll paper 50 inserted from the insertion opening 52 is formed. Is drawn out from an outlet 53 provided on the front of the print control unit 45. Further, on the side of the print control unit 45, the roll paper 5 inserted at the beginning is inserted.
A zero feeding mechanism 46 and a paper fixing lever 47 for fixing the roll paper 50 are provided, and a switch 49 for automatic paper feeding and cutting is provided on a side surface of the unit mounting portion 44b. An end portion of the unit attaching portion 44b (an upper portion of the print control unit 45) is formed with a grip portion 44c in which a plate material is bent and stacked, and the grip portion 44c is held by hand as will be described in detail later. The main body 41 can be rotated.

The support bracket 42 is made of, for example, a metal plate, is formed in a substantially U-shape with an upper opening, and is mounted on the upper surface of the display case 14 via a mounting bracket 43 made of a similar metal plate. . The main body bracket 44 has its roll paper mounting portion 44a fitted into the opening of the support bracket 42 from above and is rotatably mounted on the distal end side by a rotary shaft 48. At the distal end of the support bracket 42, when the main body bracket 44 is rotated at a substantially right angle, the main bracket 44 is bent substantially horizontally so as to abut on the lower surface of the unit mounting portion 44b to support the weight of the printer main body 44. The contact portion 42a is formed. Also, the support shaft 4 of the support bracket 42
8, two small holes 42b, 42b are formed on the side surface of the roll paper mounting portion 44a.
4d is engaged with one of the holes 24b to maintain the position of the printing state, and when the roll paper 50 is at the exchange position of the rotated roll paper 50, the convex portion 44d is engaged with the other hole 42b to perform the exchange. The position is maintained. A projection 54 made of a material such as plastic is attached to the lower end of the roll paper attachment 44a.
A receiving portion 55 made of a material such as plastic, which has a concave portion for holding the projection when the printing portion is in the position of the printing state, is attached to the upper end of the second portion.

The printer structure 4 of the lubricating device 10 having the above configuration.
0, when the roll paper 50 is to be replaced, first, the display panel 20 is opened, and the grip portion 44c of the main body bracket 44 is opened.
Is held between the protrusion 54 and the receiving portion 55 and the hole 42.
By pulling the printer body 41 forward against the holding force generated between the protrusion b and the projection 44d, the unit mounting portion 44b contacts the contact portion 42a around the rotation shaft 48 provided on the support bracket 42. Rotate about 90 degrees until they touch. As a result, the convex portion 44d enters the other hole 42b, and the rotated replacement position is maintained. In this exchange position, the holding members 51 of the roll paper 50 are located at the upper front, and the insertion opening 52 of the roll paper 50 is located at the lower front. Next, the used roll paper 50 is held by the holding member 5.
Then, a new roll paper 50 is attached, and the leading end of the roll paper 50 is pulled out and inserted into the insertion slot 52.
Next, holding the grip portion 44c by hand, the hole 42b and the convex portion 44d
Are rotated in the original direction against the holding force generated between them, and the projection 54 enters the receiving portion 55 so as to be held at the printing position. Next, by operating the feed mechanism 46, the discharge port 53 is operated.
Then, the leading end of the roll paper 50 is extended to an appropriate length, and then the paper fixing lever 47 is operated to fix the paper. Printing is possible by closing the display panel 20 to its original state,
The printed slip can be taken out from the sheet take-out port 28 provided at a position facing the discharge port 53. The printer structure 40 is configured such that the printer main body 41 includes the support bracket 4.
2 about the rotation shaft 48 provided on the
Since the holding members 51 and 51 of the roll paper 50 are located at the upper front and the insertion opening 52 of the roll paper 50 is located at the lower front, even if the display case 14 is at a relatively high position, the roll paper 50 can be replaced. The positions of the holding members 51 and 51 and the insertion opening 52 necessary for the printing can be visually confirmed, and the leading end of the paper can be reliably inserted into the insertion opening 52 by exchanging the roll paper 50. Further, since the main body bracket 44 and the support bracket 42 are provided with the protruding portions 54 and the receiving portions 55, respectively, the printing state can be maintained, and the convex portions 44d and the holes 42b are formed respectively. Therefore, the printing state and the rotated exchange state can be maintained. Further, since the plate member is folded and stacked, the grip portion 44c of the main body bracket 44 is easy to operate when rotating, and the hand is not damaged.

In the above embodiment, in the printer main body 41, at least in the printing state, the print control unit 45 is arranged on the front side of the main body bracket 44, and the holding member 51 for attaching the roll paper 50 is arranged on the back side. In addition, it is rotatably attached to the support bracket 42 on the front side of the main body bracket 44, and at the rotated exchange position, the holding member 51 for attaching the roll paper 50 and the paper insertion opening 52 for the print control unit 45 are on the front side. It is only necessary to be located on the near side that can be visually confirmed, and the shapes of the main body bracket 44 and the support bracket 42 can be arbitrarily formed,
It is not limited to the embodiment. In the embodiment, the printing state is maintained by the protrusion 54 and the receiving part 55 attached to the main body bracket 44 and the support bracket 42.
Another catch member may be used, for example, a magnet or the like.
