Abstract

PURPOSE:To keep off any drop in printing quality due to the setting of thermosensitive recording paper, by installing a guide, which is situated in both sides of a sheet and guides the sheet to an inlet leading to a recording device, in a housing case of the sheet, and forming an opening part in a position proximate to the guide. CONSTITUTION:When thermosensitive recording paper 1 is set to a housing case 2, first this housing case 2 is attached to a housing case receiver 4a in the state that a shaft 2a and a bearing 4b are joined together. Next, the thermosensitive recording paper 1 is rotated from an opening part 2d, extruding this paper 1 out. At this time, since a slit 2c of the housing case 2 and another slit 4c of a body 4 are already situated in the opposed position, the extruded paper 1 is guide by both guides 2c and 2e, passing through these slits 2c and 4c, and it is reached to a heat sensitizing head by way of a guide 4d. In a process of this extrusion, the thermosensitive recording paper 1 is not contacted but one surface, so that when the recording surface is turned to the backside, any drop in printing quality due to the setting of the paper 1 is prevented from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is used in small copying machines etc. that perform thermal recording.
This invention relates to a storage case for sheets such as recording materials.

2. Description of the Related Art Conventionally, compact copying machines that perform thermal recording have generally been constructed to hold thermal recording paper in a rolled state.

FIG. 4 is an exploded perspective view of a conventional small-sized copying machine, in which numeral 6 indicates the copying machine main body, and the main body 6 has a storage case holder 6a%.
The bearing has a groove 6b and a slit 6C. 7 is a storage case having a slit 7a and a shaft 7b; 8 is thermal recording paper that is held in a rolled state inside the storage case 7 and is taken out from the slit 7a; and 9 is a lid of the storage case 7. .

The attachment of the thermal recording paper 8 to the conventional small-sized copying machine configured as described above will be described below.

First, as shown in FIG. 4, the thermal recording paper 8 is taken out from the slit 7a, passed through the slit 6C which is the entrance to the recording means (not shown in the figure) in the main body 6, and held in that state. While holding the storage case 7, place the storage case holder 6.
Attach to a.

Problems to be Solved by the Invention However, in the above-mentioned conventional configuration, when the thermal recording paper 8 is passed through the slit 6C, the storage case 7 is placed in the storage case receiver 6a to prevent the thermal recording paper 8 from coming off the slit 6C. The problem is that it is very difficult to attach the thermal recording paper 8, and that both sides of the thermal recording paper 8 are touched when the thermal recording paper 8 is pulled out, and that the thermal recording paper 8 is not removed from the slit 6c. Equivalent to Fl,
55. Since it is necessary to pull out the thermal recording paper 8, there is a problem in that the print quality of the first part of the thermal recording paper 8 deteriorates.

Means for Solving the Problems The present invention comprises guides located on both sides of the sheet that guide the sheet to the entrance to the recording means outside the casing, and an opening formed in the casing at a position close to the guide. be.

Effect With the above configuration, by feeding the thermal recording paper through the opening after attaching the storage case, the thermal recording paper can be easily set in the copying machine, and only one side of the thermal recording paper is touched. Therefore, by locating the surface on which recording is performed on the back side, it is possible to prevent the print quality from deteriorating due to setting the thermal recording paper.

Embodiment FIG. 1 is an exploded perspective view of a storage case in an embodiment of the present invention, in which 1 is a roll of thermal recording paper, and 2 is a cylindrical storage case that holds the thermal recording paper 1 inside. The storage case 2 includes a fixed shaft 2a, a slit 2b through which the thermal recording paper 1 passes, and a guide 2 on the upper side of the thermal recording paper 1.
c, an opening 2d provided in the guide 2c, and a guide 2e below the thermal recording paper 1. 3 is storage case 2
It is the lid of

FIG. 2 is an exploded perspective view of a small copying machine to which the storage case 2 of this embodiment is attached, and 4 indicates the main body of the copying machine, and the main body 4 has a storage case holder 4a, an N bearing 4b, and a slit 4c. ing. Further, as shown in more detail in FIG. 3, a guide 4d for the thermal recording paper 1 to a thermal head (not shown in the figure) for performing thermal recording is formed in the main body 4.

Regarding this embodiment configured as described above, attachment of the thermal recording paper 1 will be explained below.

First, with the shaft 2a and bearing 4b aligned, the storage cassette 2 is attached to the storage case receiver 4a as shown in FIG. Next, the thermal recording paper 1 is rotated through the opening 2d, and the thermal recording paper 1 is pushed out. At this time, the slit 2C of the storage case 2 and the slit 4c of the main body 4 are already in opposing positions, so the extruded thermal recording paper 1 is guided by the guides 2c and 2e, passes through the slits 2c and 4C, and then passes through the guide 4d. It then reaches the heat-sensitive head. During this extrusion process, only one side of the thermal recording paper 1 is contacted, so by setting the recording surface on the back side, it is possible to prevent the print quality from deteriorating due to the setting of the thermal recording paper 1.

Effects of the Invention The present invention includes guides located on both sides of the sheet to guide the sheet to the entrance of the recording means outside the casing, and an opening is formed in the casing at a position close to the guide.
After attaching the storage cassette, the thermal recording paper can be easily loaded into the copying machine by feeding it out from the opening, and since only one side of the thermal recording paper is touched, the recording process is easier. By locating the exposed surface on the back side, it is possible to prevent the print quality from deteriorating due to setting the thermal recording paper.
