If the cover is in the second position with a surface that aligns with the sheet feeding direction, the second cover becomes a cut sheet guide when using cut sheets, and neither the tractor cover nor the cut sheet guide can be moved. There is no need to remove them either, so there is no need for a place to store them.

<Embodiments> Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 and 3 are perspective views showing the housing device according to the invention when using continuous paper, that is, when using a tractor feeder. A paper feeder 34 is housed inside the housing body 30, and an opening on the rear upper surface of the housing body is covered by a printer cover 31. printer cover 31
consists of two parts, the first part 31a is pivotably supported at its front end by the housing main body 30 via a pivot shaft 32 facing in the lateral direction, and the second part 31a of the printer cover 31 The portion 31b is rotatably supported at its intermediate portion by the first portion 31a of the printer cover 31 via a pivot shaft 33 that faces laterally.

In the state shown in FIGS. 1 and 3, both sections 31a and 31b of the printer cover 31 form a single cover that covers the rear upper surface of the housing body 30 and is in the continuous paper use state. A certain paper feeding device 34 will be protected.

7 and 9 show the paper feeding device 34 in detail. A cylindrical platen 3 and a pair of transverse shafts 4.5 are installed between frames 2.2' provided on the left and right sides of the upper part of the printer. A pair of tractor feeders 7 are fitted onto the transverse shaft 4.5 so as to be movable in the axial direction.

The frames 2.2' are each divided into upper and lower parts, and the upper frame 2a can be tilted upward by a pivot 11 supported by a support plate 6 erected at the rear of the lower frame 2b. Supported. The transverse axes 4.5 are received in substantially horizontal slots 8 and rearwardly upwardly inclined slots 9 cut into the side plates of the upper frame, respectively.

The end of the transverse shaft 4 projecting into one of the frames 2 is fixed to one end of a connecting plate 12 , the other end of which is attached to the other end of the connecting plate 12 , which extends into each frame 2 . The plunge part is rotatably supported. Furthermore, the same end of the transverse shaft 5 is pivotally supported by the intermediate part of a link 13, a gear 14 is rotatably supported at one end of the link 13, and a torsion coil is mounted at the other end of the link 13. One end of the spring 19 is locked, urging the link 13 in the counterclockwise direction in FIG.

The gear 14 is a gear 1 fixed to the protruding end of the transverse shaft 5.
5 and a gear 3a fixed to the platen 3. Therefore, when the platen 3 is rotationally driven by a drive means (not shown), the torque is applied to the gears 14 and 15.
The transverse shaft 5 is rotated through the shaft 5, and a tractor pin belt suspended from a pulley (not shown) fixed to the desk shaft 5 is driven, and the pin engages with the paper feed hole of the printer paper. The required paper feeding can be performed. Note that this tractor feeder 7 is of a type in which pins of a pin belt protrude from its upper and lower surfaces.

A link 16 is pivotally supported at the protruding end of the other transverse shaft 4, and the other end of the link is pivotally connected by a pin 18 to an intermediate portion of an arm 17 that is pivotally supported by the pivot shaft 11.

A lever 22 is pivotally attached to the rear part of the lower frame 2b by a pivot pin 21, and an engaging portion 22a provided at one end of the lever 22 engages with a locking pin 20 provided on the printer main body side. The entire frame 2 can be attached and detached by connecting and detaching.

Furthermore, a roller 26 that is rotatable around an axis parallel to the platen is in contact with the lower outer peripheral surface of the platen 3.
A paper guide 25 made of a curved plate is provided adjacently.

In the other frame 2', the transverse shaft 4.5 is simply received in a slot similar to that described above and is likewise connected by a connecting plate similar to the connecting plate 12.

Therefore, in this state, the continuous paper is introduced from an opening (not shown) at the back of the second portion 31b of the printer cover 31, and is fed toward the platen 3 by, for example, the lower surface of the tractor feeder 7. After passing through the platen 3, it is sent out from the opening toward the rear of the printer device.
