In addition to losing the integrity of the appearance, there is a risk of scratches etc. on the upper surface of the upper case 1a.Also, when using the holder, the downward direction is restricted by the stopper 8, but there is no upward restriction. , it becomes difficult to hold the holder 6, for example when carrying the main body when loading roll paper, or when the main body 1
When using the roll paper by hand, there is a problem in that it is difficult to smoothly feed the roll paper.

Therefore, the present invention has been made to solve these problems, and provides a recording medium holding device that can be stored so as to maintain the integrity of the appearance when not in use, and can securely hold the recording medium when in use. The purpose is to

[Means for Solving the Problems] In order to solve these problems, the present invention provides a holding member that holds a roll-shaped recording medium so as to be rotatable with respect to the recording device housing, so that it can be held when not in use. We adopted a structure in which the components are stored at the bottom of the casing and are held and fixed to the casing during use.

[Example] The wooden invention will be described in detail below based on the example shown in the drawings.

One embodiment of the present invention is illustrated in FIGS. 1 to 4, and in these figures, the same parts as in FIG. 5 are given the same reference numerals, and the explanation thereof will be omitted.

FIG. 1 shows the external appearance of a calculator with a printer in which the device of the present invention is used. A keyboard section 2 for inputting numerical values and calculation contents is provided on the upper surface of the front half of the upper case 1a, and a keyboard section 2 is provided on the upper surface of the central portion. is the display section 3 that displays input data and calculation results.
However, in the second half, input data and calculation results are stored on roll paper 4.
A recording section 5 is provided for recording. Furthermore, a battery is built into the main body 1 and serves as a power source for driving an arithmetic circuit and a printer.
